  • Organizational Characteristics of B2B Adopters in the Canadian Manufacturing Sector

    Resource Type:
    Article
    Creator:
    Kumar, Vinod D., Fuksa, Michael, and Kumar, Uma
    Abstract:
    This paper presents selected preliminary results from a study of B2B e-commerce adoption by Canadian manufacturing firms. The goal of the broad research project IS to describe the behaviour of Canadian manufacturers with respect to adoption of B2B technologies and to identify factors which distinguish adopters from non-adopters of B2B. The study focuses on the organizational characteristics of adopters of B2B e-commerce technologies and attempts to outline the features which differentiate them from non-adopters. Preliminary analysis shows the existence of three distinct B2B adopter types: non-adopters, partial-adopters and full-adopters. Leadership related variables appear to be the most important determinants of adoption.

  • The New Age of Accounting Regulation Canada and the United States

    Resource Type:
    Article
    Creator:
    Pollanen, Raili and Pollanen, Eric M.
    Abstract:
    This paper reviews major differences between the accounting regulatory systems in Canada and the United States. In the U.S., the Sarbanes-Oxley Act of 2002 governs responsibilities of management, auditors, and Boards of Directors related to internal control over financial reporting. In Canada, a series of Multilateral Instruments under provincial jurisdiction serves similar objectives. As compared to the U.S., the Canadian system is more decentralized and principles-based allowing a greater degree of responsibility to the accounting profession for standard setting and oversight. The Canadian approach has resulted in weaker regulation, slower implementation, and greater influence by the accounting profession. These findings imply that accounting regulations should be tailored to fit the political and institutional structures of the adopting country.

  • Critical Success Factors in Technology Transfer from Government Laboratories to Private Sector

    Resource Type:
    Article
    Creator:
    Kumar, Uma and Uruthirapathy, Aareni
    Abstract:
    Each year the Canadian government allocates a significant amount of money for science and technology. A major portion of this allocation goes for R& D. In order to enjoy adequate return, technologies that are developed in Canadian federal labs need to be transferred to the public effectively. There are critical factors in technology transfer which play a key role in determining the effectiveness of this transfer process. This study examines the technical, organizational, and people factors which can enhance technology transfer from government laboratories.

    Abstract:
    Implementation of quality management practice in E-Commerce (EC) is a relatively new challenging area to researchers and managers. Proliferation of EC provides an opportunity to quality management gurus to reshape quality dimensions suitable for real sustainability, expansion, and success of EC. Based on the underpinning principles of Total Quality Management (TQM) and quality management practice this paper focuses on the quality dimensions required for launching a successful EC as the competitive edge in gaining market leadership. This article postulates a model to integrate quality management in EC.

    Lu, Irene, Cray, David, and Heslop, Louise A.
    Abstract:
    Surveys of Australian consumers before and after French nuclear testing in the Pacific show clear evidence of negative responses of consumers to the 1995 testing. Although evaluations of French products did not decline, evaluations of France and the French did. However, by 2005 ratings of French products and France had more than recovered. A model of effects among country and product belief sets is proposed and tested. The model is strongly supported and helpful in understanding the process of image recover.

  • The Role of Export Processing Zones in Development and International Marketing Strategy

    Resource Type:
    Article
    Creator:
    Malhotra, Shavin and Papadopoulos, Nicolas G.
    Abstract:
    Export Processing Zones (EPZs) are areas within developing countries where business is offered special incentives and a barrier-free environment in order to promote economic growth by attracting foreign investment for export-oriented production. Most developing countries now have EPZs, and the number of zones, number of firms operating within them, and volume of business are growing rapidly. Yet studies of the EPZ phenomenon by business researchers are virtually non-existent, leading to poor understanding of its role in international marketing. This paper draws from the economics literature to provide an integrative review of the EPZ concept, discusses its importance for host nations and international business, and provides suggestions for future research.

  • Measures of Identity Fraud

    Resource Type:
    Article
    Creator:
    Kumar, Vinod D., Movahedi, Bahar, Lavassani, Kayvan, and Kumar, Uma
    Abstract:
    Identity fraud (IDF) is the fastest growing white-collar crime in many countries and specifically in developed countries. IDF is not a new phenomenal in human societies; the history of IDF can be traced back to hundreds of years ago. What has made it the center of attention in the past few years is the acceleration in the frequency and the impacts of IDF to individuals and businesses. One of the preliminary steps in managing IDF as a global phenomenon is to understand the scope of the problem and measure its different aspects. By realizing the importance of developing measurement systems in this area, and the recognition of a gap in this area of research, this study presents the previous approaches in developing IDF measurement systems, and uses them as benchmarks for developing and proposing a comprehensive measurement system for assessing IDF.

    Article
    Creator:
    de Grosbois, Danuta, Kumar, Uma, and Kumar, Vinod D.
    Abstract:
    The problem of identity theft is complex, spans the boundaries of many organizations, companies and countries, and affects numerous entities in different ways at different times. However, given the nature of the problem, it is extremely difficult and costly for an individual or an organization to fight it on its own. An increasing number of practitioners and researchers have started to indicate that the success of identity theft management relies on joint efforts of different stakeholders. Collaboration, generally defined as 'working together to some end' is believed to have the potential of delivering numerous benefits to its participants when properly executed. This paper discusses different aspects of collaboration efforts undertaken by organizations in order to fight identity theft.

  • The Role of Behavioural Activation and Inhibition in Advertising Appeals

    Resource Type:
    Article
    Creator:
    Papadopoulos, Nicolas G. and Murphy, Steven
    Abstract:
    Advertising appeals are central to the effectiveness of advertising and have been studied extensively. However, past research has focused primarily on examining the effects of one or another type of appeal on consumers, and little is known about the concept of an advertising appeal itself. As part of a broader program intended to address this gap, this paper examines the role of underlying motivational forces in the development of consumer attributions regarding advertising appeals. More specifically, we are centrally concerned with examining under what conditions emotion states, personality traits, and underlying motivations may lead to product judgements and subsequent (purchase) behaviour.

  • Competitive and Value Effects of Bank Privatization in Developed Countries

    Article
    Creator:
    Otchere, Isaac
    Abstract:
    This paper presents a comprehensive analysis of the performance of privatized banks in developed countries. Consistent with the competitive effects hypothesis which asserts that privatization could hurt rivals, we find that the rival banks reacted negatively to news of bank privatization in developed countries. The competitive effects are stronger in cases where government ownership decreases significantly. Contrary to the findings of prior studies that examine the performance of privatized banks in developing countries, we find that privatized banks in developed countries experienced significant improvements in operating performance and stock market performance in the post privatization period.

  • Critical Theory in MIS Research, 1990-2001 : Looking Back and Moving Forward

    Resource Type:
    Article
    Creator:
    Neilson, Leighann
    Abstract:
    A review of five major journals in the Management Information Systems (MIS) field reveals that the majority of research articles engaging with Critical Theory, from the period 1990 to 2001, are of a conceptual nature, focusing primarily on systems development. Two reasons are suggested for the comparatively low level of engagement with Critical Theory in empirical research efforts: lack of a critical theory method and reluctance to engage with the theory's emancipatory commitments. A critical theory method that encompasses both quantitative and qualitative data collection methods is advanced. In addition, a more practiceoriented way of thinking about emancipation is proposed.

    Abstract:
    This paper reviews the existing evidence for dual discrimination based on gender and ethnicity for minority/immigrant women. It focuses on income inequalities between minority/immigrant women and other groups. The effects of human capital, occupational segregation, sector segregation and discrimination or stereotyping on earnings gap are identified. The paper also proposes that a preponderance of minority females in certain occupations may result in a devaluation of wages and lowering of prestige in these occupations. The unique set of stressors experienced by minority/immigrant women that may affect access to jobs as well as performance on the job are also discussed.

    Abstract:
    This paper provides empirical evidence on the growth, financing activity, and operating performance of Canadian business income trusts. We find that business income trusts are growing in terms of total assets and sales revenues. They frequently acquire other businesses in post-IPO period. We also find that income trusts are likely to issue third-party debt to finance acquisitions. Median operating return on total assets decreases after an business income trust IPO, indicating an operating performance inferior to that in pre-lPO years.

  • A Markovian Simulation-based Model for Predicting the Breakage Factor in Loyalty Programs Industry

    Resource Type:
    Article
    Creator:
    Nsakanda, Aaron
    Abstract:
    One problem faced by a profit center loyalty reward program firm is that of determining the percentage of the points (the so called "breakage factor or "breakage rate" in loyalty programs industry) accumulated each year that end up not ever being redeemed by members, and that should therefore, be recognized as revenue in the establishment of the periodical financial statements. A higher breakage rate will contribute to increase the net income and profitability on the financial statements. This in turn would offer a competitive advantage to a firm in attracting and pricing new third party partners, developing company strategic plans, and managing the overall yearly reward capacity. In this paper, we propose a quantitative methodology for determining the breakage rate in Loyalty Reward Programs (LRP). The proposed methodology is a simulation-based approach in which the accumulation and redemption of "points" is modeled as a stochastic process. An application of the approach to a real-life context is discussed.

  • Putting the Romance Back in Teams: Is Trust the Key to Unlock Knowledge Sharing?

    Resource Type:
    Article
    Creator:
    Tuer, Frances L.
    Abstract:
    One reason teams are seen to be a high-performance work practice (HPWP) is that the diversity of team member knowledge, skills and abilities, known as cognitive resource diversity supposedly brings new perspectives, information, ideas and resources to the solution of problems and the exploration and exploitation of opportunities. However, to date the performance of heterogeneous teams has been disappointing with the most common finding being increased conflict. Based on social identity and social exchange theories and building onto Mayer, Davis & Schoorman's (1995) classic integrative model of trust, this paper proposes that trust is a critical mediator in the relationship between cognitive resource diversity and within-team knowledge sharing.

  • The Strategic Dimensions of Information Systems Capability: An Evolutionary and Resource-based View

    Resource Type:
    Article
    Creator:
    Sangwan, Hemant, Yu, Ma, and Nitin, Mehta
    Abstract:
    The paper addresses important issues regarding how consumers' purchase decisions in a product category are influenced by market mix variables in other categories. We propose a structural analysis of multi-category purchase decisions, where we simultaneously model and estimate consumers' purchase incidence, brand choice and quantity choice decisions across multiple product categories. Addtionally, we study the role played by umbrella brands in influencing the decision made by consumers. We propose a structural model where all the three decisions are derived from the consumer's global utility maximization. Such structural analysis is important from the perspective of (i) a retailer whose objective is to maximize profits over all product categories, and (ii) a manufacturer whose objective is to maximize profits over its entire product line. Our analysis highlights the importance of studying consumers' purchase decisions in a multi-category context which can not be addressed by studying each category in seclusion.

    Article
    Creator:
    Skowronski, Mark
    Abstract:
    Identification of effective and cost-efficient compensation practices for recruiting and retaining expatriate employees is becoming increasingly important in today's global labor market. This paper proposes a study to investigate perceptions of fair compensation for expatriate employment using the tenets of equity theory. Participants will specify an "equitable" monetary bonus for hypothetical overseas assignments of different lengths and locations. Relying on Konopaske's and Werner's (2002) propositions, the author predicts the following: 1) Short-term overseas assignments will require a larger "foreign service premium" (monetary bonus) than domestic relocation, 2) Long-term expatriate assignments will require a larger premium than short-term or domestic relocation, and 3) Relocation to a developing country will require a larger premium than relocation to an advanced industrialized nation or to a domestic location. A methodology and data analysis strategy are described.

  • The Positive Effects of Incivility in the Context of the Armed Forces: Exploring Work Context as a Moderator of Incivility

    Resource Type:
    Article
    Creator:
    Rostis, Adam
    Abstract:
    In the typology of harassment and aggression in the workplace, workplace incivility is situated as a non-aggressive, low intensity form of deviant behaviour with an uncertain intent to cause harm. The importance of incivility to organizational theory and human resource management is that it may have a negative effect on organizational outcomes and more importantly it may be a precursor for more overt forms of workplace violence. Two potential influences on the effects of incivility are personality and workplace context; the latter of these two has not been sufficiently explored in the literature. This paper will take one step towards addressing this gap by examining the ways in which incivility is moderated in the context of military organizations. The result of this contextual examination of incivility will be a proposal that incivility may have a positive effect through the development of coping strategies for stressful situations encountered by armed forces.

  • Involuntary Downsizing: The Impact of a Labour Shortage

    Resource Type:
    Article
    Creator:
    Pyper, Rhonda L.
    Abstract:
    Labour shortages are imminent in a variety of different industries, particularly those that require high levels of skills. Organizations will need to plan for these shortages as many of the solutions will have fairly long lead times before an impact is felt. One area from which short-term gains may be achieved is the reduction of voluntary turnover, particularly the loss of productive employees. An area with potential for longer-term success in combating the labour shortage is in restructuring. Through restructuring, organizations can redesign the work processes so that when employees do leave, the position will have to be reworked and a replacement may not be needed. The organization will be shrinking in headcount, but it will remain as productive as it was before downsizing due to efficiencies gained; it will have successfully navigated "involuntary downsizing". The purpose of this paper is to develop the concept of involuntary downsizing" by expanding the definition of downsizing to include situations in which organizations are competing in diminishing labour markets. Similar to the current concept of downsizing, organizations will need to accomplish more, with fewer resources; however, the cause of the downsizing and the solutions that are available will be different.

  • How May I Help You? Conceptualizing the Benefits of High Performance Work Practices on Emotional Labour Pressures in the Hospitality Industry

    Resource Type:
    Article
    Creator:
    Murray, William
    Abstract:
    The hospitality industry relies on front-line staff members to provide high quality service experiences to encourage repeat business. Unlike the manufacturing industry that separates the production of goods from the delivery to customers, professionals in the hospitality industry realize that customers evaluate their "product" through perceived service quality levels (Ottenbacher & Howley, 2005). Although types of service may differ, industry operators and researchers agree that both customer satisfaction and service quality are critical prerequisites for customer retention (Cronin & Taylor, 1992). Consistent service quality demands a workforce with strong emotional display management skills; however, displays of unfelt feelings, or "acting", can create intense emotional strain for service providers. This paper will examine the emotional labour pressures experienced by service workers and outline theoretical mitigating influences provided by high performance work practices (HPWP). Links will be drawn between decreased employee turnover, increased customer satisfaction and customer retention.

  • A Product of 'His' Time? Exploring the Construct of the Ideal Manager in the Cold War Era

    Resource Type:
    Article
    Creator:
    Mills, Albert J. and McLaren, Patricia Genoe
    Abstract:
    Managers are often measured against an ideal that is treated as a tangible object which is stable across generations. It is the contention of this paper that the ideal manager is, in fact, a social construct that is a product of the political and social context within which it exists. Different periods in time create unique typifications of the construct, and the ideal manager is not independent of its environment. The socially constructed nature of the ideal manager will be illustrated through the analysis of the construct at one specific point in time, the internal Cold War in the years following the Second World War and ending in 1960. While widely studied in most disciplines, the Cold War has been largely ignored in the management literature, and therefore provides us with a unique perspective from which to assess the impact of context on the standard to which managers are held.

  • Seeing and Unmaking Civilians in Afghanistan: Visual Technologies and Contested Professional Visions

    Resource Type:
    Article
    Creator:
    Wilke, Christiane
    Abstract:
    This article examines the politics of 'seeing' civilians in Afghanistan with a focus on the 2009 Kunduz air strike. Drawing on the literature on professional vision and professional knowledges, I ask how divergences in the 'ways of seeing' between different professional communities can be explained, and how they are resolved in practice. 'Seeing,' I argue, is based on talking. The vocabularies with which we describe the world and understand our relationships shape how we 'see'. As a consequence, Afghans gathered around a truck can appear an 'immediate threat' or not -- depending on the ideological prisms at work. The article suggests that we need to treat professional vision as necessarily contested and examine how professionals are socialized into accepting one way of seeing as valid. Seeing is based on talking, and we need to talk about how we see (violence).

    Abstract:
    This paper will provide insight into the personality dimensions that can be attributed to performing arts awards, and thus generate a scale to measure these dimensions. This area of work rests upon the idea that there is self-concept congruency between a viewer and product or service, and that there are instances where attributes of a human nature can be, in fact, attributed to them. The study will look particularly at a mixed sample of televised performing arts awards shows (The Academy Awards, The Prime-Time Emmy Awards, The Tony Awards, The Grammy Awards and The Golden Globe Awards) and the various motivations and interests of viewers to watch, or not watch, such shows. Based upon its position in the literature and its intended contribution, this study will propose a four-step scale development process.

  • The Internationalization of Malaysian Firms into Foreign Markets

    Resource Type:
    Article
    Creator:
    Ismail, Jannatul Firdaus
    Abstract:
    Available data indicate that economic conditions, exports performance and foreign direct investment from Malaysia increased significantly in the 1990s. Existing literature on the internationalization of firms is based on the study of firms from developed countries and does not directly apply to the case of firms based in developing economies, and Malaysia particularly. Based on this phenomenon, this study attempts to examine the process of internationalization among Malaysian firms into the foreign markets and compare the internationalization process of Malaysian firms with other developed countries. This study will contribute to the knowledge gap with empirical data from rapidly internationalizing firms, in respect of the Malaysian firms' experiences, organizational learning and capability creation that will offer fruitful approaches to understanding the dynamic of firms' expansion. The resulting model could assist policy makers to improve existed support programs for businesses to overcome barriers and enhance performance in internationalization process.

  • Out of the Closet: An Exploration of the Role of Work Dress

    Resource Type:
    Article
    Creator:
    Dyke, Lorraine and Elliot, Statia
    Abstract:
    Despite the prevalence of formal and informal standards for employee attire, research on its role is limited. Social psychological theories suggest that work attire can be a meaningful, expressive symbol associated with one's occupational identity. Organizational theories suggest that work attire can affect both individual and organizational outcomes. Bridging these perspectives, this study considers work attire's potential to influence micro and macro organizational dynamics. A framework of the dimensions influencing factors and outcomes of work dress is used to assess the results of a poll of members of the Canadian Forces, an organization whose work attire is highly conspicuous and rigidly homogeneous. Though a slight majority of participants responded that their uniform did not impact their operational focus, comments indicate both organizational influences and individual concerns with specific attributes of attire. Attitudes toward work attire may be indicative of broader issues of organizational identity.

    Abstract:
    This paper identifies some of the challenges facing expatriates using an autoethnographic account of situations experienced by the author during her first year of work at a financial services company in Hong Kong. These experiences reveal an erratic business world of apparent nonsense and uncertainty, incomprehensible to an outsider. The challenges facing expatriates stem from the stress and anxiety affecting their work, family and social interactions within the foreign culture. Success in the new environment is dependent on the expatriate's ability to adjust to the new culture. An overview of the current research on the expatriate experience is provided to help the reader make sense of the autoethnographic situations.

  • What Do We Know About Collaborative Maturity? : A Review of the Literature and Research Track

    Resource Type:
    Article
    Creator:
    Daoudi, Jaouad and Bourgault, Mario
    Abstract:
    Working in collaborative and dispersed (C&D) settings is now common for project teams, especially for those active in multinational companies or in international contexts. The concept of "collaborative maturity" has recently been proposed by various authors in order to identify and measure the competence of a firm working in C&D mode. Many models of collaborative maturity have been proposed, reflecting the increasing importance of this area of research. However, the existing literature is spread among multiple journals in various fields of research. For a better understanding of collaborative maturity and how it is measured, a thorough literature review is conducted and an extension of existing research is proposed. This will serve as the theoretical background for future empirical research. The results should be useful for project managers and academicians with an interest in C&D projects.

  • Furthering Collaborative Strategic Management Theory: Process Model and Factors Per Phase

    Resource Type:
    Article
    Creator:
    Clarke, Amelia
    Abstract:
    Social problems, such unsustainable development, can be too large for any one organization to tackle alone so are increasingly being addressed through cross-sector multi-organizational collaborations. One of the approaches being taken is formulating and implementing a collective (alternatively named collaborative) strategy. Despite the increasing usage of collaborative strategic management in practice, there is relatively little literature on this approach, particularly when considering the implementation of the collaborative strategy. This paper builds on existing interorganizational collaboration theory and organizational strategy implementation theory to determine: 1) a conceptual process model of collaborative strategic management; and 2) factors which affect each phase of cross-sectoral social-oriented collaborative strategic managment.

  • Technology Scanning Scale Dimensions

    Resource Type:
    Article
    Creator:
    Alam, M. S.
    Abstract:
    The paper identifies the characteristics of firm activities that constitute its technology scanning dynamic capability, which enables the firm to translate information about customer needs into information about tangible ways to introduce new products and services to satisfy those needs. The ability to find a specific actionable way to address customer needs is proposed to be measured by a latent construct called technology scanning. Using the literature on marketing, innovation management, knowledge management, new product development, and economics, five dimensions are identified for a technology scanning scale. A strong presence of 'technology scanning' ensures that the firm's resources are targeted to find the solution of the problems that matters most, the ones that were identified as a consequence of high level of market orientation of the firm. This work would shed some light on how managers might solve the problems and needs of the customers identified through market orientation practices. When market orientation guides technology scanning activities, the outcomes are more desirable to the firm.

However, strategic alliances are mostly examined from a transaction cost economics perspective, and the results on performance are inconclusive at best. This paper proposes an alternative lens - the resource-based view - and applies an extended version of it to explain the performance of firms in IT-based alliances. A conceptual model is developed that examines the impact of shared information technology resources on firm performance. Also, a measurement scale for these resources is developed and preliminarily validated.

    Abstract:
    Entrepreneurship is a recognized concept both for research and practice. It is possible to find university courses, research published in specialized journals, associations dedicated to entrepreneurship promotion and governmental support. In a regional economic development context, a special form of entrepreneurship could achieve other objectives. Social entrepreneurship is an emergent concept earning more popularity than ever around the planet. However the concept is not well known. The objective of the paper is to present an overview of the social entrepreneurship concept.

  • The Use of Affect in Positioning Strategy

    Abstract:
    This paper examines the role of affect in marketing positioning strategy and individual positioning judgements. We examine affect in both the marketing and positioning literatures and argue that vestiges of the dual mind perspective are alive and well in positioning. Viewing 'thinking' and 'feeling' as entirely separate (as in utilitarian vs. hedonic product distinctions) runs counter to advances in neuroscience and devalues individual differences and brain functioning. As a result of our own coding of positioning dimensions, we advocate for a greater understanding of the complex interplay between affect and cognition in positioning strategy and judgements.

    Article
    Creator:
    Elliot, Statia and Papadopoulos, Nicolas G.
    Abstract:
    Potential synergies between international trade and tourism are viewed optimistically by governments, yet research to assess their association is limited. To gain an understanding of trade and tourism relationships, this paper reports on a study which examines both product-related and tourism-related place image effects on consumer behavior simultaneously. Using the U.S. as the country of focus, key product and travel relationships are measured by structural equation modeling of consumer data from South Korea. Findings support the cross-over effect between one's beliefs about a country as a destination and as a producer, and one's willingness to travel to it and/or buy its products, and most strongly, that product beliefs affect views of travel destinations.

    Resource Type:
    Article
    Creator:
    Pollanen, Raili
    Abstract:
    This paper provides a critical review of literature on management controls and their context. The review indicates that more emphasis has been placed on organizational than environmental factors and that the effectiveness of different controls in different contexts remains practically unaddressed. In general, research has been ad hoc and focused on results-oriented financial controls, short-term efficiency, and individual level of analysis. Even for commonly studied topics (e.g., budget controls), evidence has often been inconsistent and limited to manufacturing organizations, with little integration and refinement of previous theoretical models based on new evidence. Further research is required to investigate the relative importance of different financial and nonfinancial controls in different types of organizations in order to develop more comprehensive performance measurement and management frameworks.

  • The Strategic Dimensions of information Systems Capability: An Evolutionary and Resource-based View

    Resource Type:
    Article
    Creator:
    Grant, Gerald and Liebenau, Jonathan
    Abstract:
    Research emphasizing evolutionary and resource-based perspectives of the firm highlights the importance of core capabilities as sources of superior performance, and views capabilities in computer-based IT systems as instrumental in leading to strategic advantage. However, the asymmetrical results from such systems present a somewhat confusing picture as to the key issues that managers should be addressing. We present an approach to IS capability development that applies a combined evolutionary and resource-based perspective. We propose that IS capability is determined along three strategic dimensions and will result from effective and sustained efforts in three complementary areas that are discussed in this paper. We use three case studies to illustrate the use of the proposed IS capability framework in analyzing information systems in organizations.

  • A Critique of Partial Least Squares, and a Preliminary Assessement of an Alternative Estimation Method

    Resource Type:
    Article
    Creator:
    Thomas, Roland, Cedzynski, Marzena, and Lu, Irene
    Abstract:
    Partial least squares (PLS) is sometimes used as an alternative to covariance-based structural equation modeling (SEM). This paper briefly reviews currently available SEM techniques, and provides a critique of the perceived advantages of PLS over covariance-based SEM as commonly cited by PLS users. Specific attention is drawn to the primary disadvantage of PLS, namely the lack of consistency of its parameter estimates. The instrumental variables (IV) /two stage least squares (2SLS) method of estimation is then described and presented as a potential alternative to PLS that might yield its perceived advantages without succumbing to its primary disadvantage. Preliminary simulation results show that: PLS parameter estimates exhibit substantial bias when the number of items is moderate; SEM-based methods yield lower bias; and IV/2SLS estimates may indeed provide a viable ordinary least squares (OLS)-based alternative to PLS.

  • Relationships among Evaluative Criteria, Uncertainty, Organizational Size, and Performance: Empirical Evidence in Public Organizations

    Article
    Creator:
    Pollanen, Raili
    Abstract:
    This survey study of senior municipal administrators examines the use of evaluative criteria in managerial performance evaluation and extends previous findings in the public sector context. The results reveal that the use of evaluative criteria is very similar to that found in Otley and Pollanen's (2000) public-sector study, but significantly different from those reported in several private-sector studies. Substantially lower proportions of budget-based criteria are found in both public-sector studies than in private-sector studies. Performance is higher under low- than high-uncertainty conditions and in larger than smaller organizations. The findings suggest that different evaluative criteria may be appropriate in the public and he findings suggest that different evaluative criteria may be appropriate in the public and private sectors, and that uncertainty and organizational size may affect performance.

  • Particle-based participating media rendering using density octrees

    Resource Type:
    Article
    Creator:
    Whitehead, Anthony D. and Monette, Richard
    Abstract:
    In order for computer generated imagery to recreate the characteristic visual appearance of phenomena such as smoke and fog it is necessary to compute the way in which light interacts with participating media. In this work we present a novel technique for computing volumetric single scattering lighting solutions for particle-based inhomogeneous participating media data sets. We seek to calculate volumetric lighting solutions for particle-based data sets as such data sets have the advantage of being spatially unbounded and relatively unrestricted with regard to memory as compared to uniform grids. In order to perform the calculations which are required for computing such a lighting solution, we introduce a novel octree based data structure. We refer to this new data structure as a density octree. The design of the density octree allows for efficiently computing light attenuation throughout the spatial extent. Using our data structure, we are able to produce high quality output imagery of arbitrary particle data sets in the presence of arbitrary numbers of lights.

    Abstract:
    This study uses an exploratory qualitative design to examine the lived experience of one group of service users on community treatment orders (CTOs). The study was designed and completed by four graduate students at Carleton University School of Social Work. Despite the unique features of CTO legislation in Ontario, many findings from this study are remarkably similar to findings of research conducted in other jurisdictions. What is unique in our findings is the lack of focus on the actual conditions and provision of the CTO. The issue for our participants was less about the CTO itself, and more about the labels, control and discrimination associated with severe mental illness. Cette étude utilise un concept qualitatif et exploratoire pour examiner les expériences vécues d’un groupe qui utilise les ordonnances de traitement en milieu communautaire (OTMC). Cette étude a été designée et complétée par 4 étudiants de l’école de service social de l’université Carleton. Malgré les nombreux aspects uniques de la loi gérant les OTMC de l’Ontario, plusieurs résultats de cette étude sont remarquablement similaires aux résultats découverts dans de différentes juridictions. L’élément unique de cette recherche est le manque de focus sur les conditions véritables et les provisions des OTMC. La problématique encourue par les participants n’était pas au sujet des OTMC en soi, mais plus tôt au sujet de l’étiquetage, du contrôle, et de la discrimination associé aux troubles de santé mentale sévères.

    Creator:
    Tudin, Susan
    Abstract:
    Every year, for over three decades, Carleton University in Ottawa, Ontario has participated with other local educational institutions in providing a week-long instruction program that introduces young students to higher education. Highly motivated participants in grades 8 – 11 and numbering over 3,000 attend from several school boards in both eastern Ontario and western Quebec. The Enriched Mini Course Program has become an important recruitment tool for each institution, and at Carleton University, over 50 enriched mini courses are offered including one recent addition by the MacOdrum library staff. In this article, the author recounts how leading an enriched mini course for millennials in the university library's new Discovery Centre is an innovative initiative that demonstrates the significance of the academic library in the local community, and how staff collaboration helps to develop team building and positive vibes with the millennials.

    Abstract:
    We test for the presence of time-varying parameters (TVP) in the long-run dynamics of energy prices for oil, natural gas and coal, within a standard class of mean-reverting models. We also propose residual-based diagnostic tests and examine out-of-sample forecasts. In-sample LR tests support the TVP model for coal and gas but not for oil, though companion diagnostics suggest that the model is too restrictive to conclusively fit the data. Out-of-sample analysis suggests a random-walk specification for oil price, and TVP models for both real-time forecasting in the case of gas and long-run forecasting in the case of coal.

  • Age-at-arrival differences in home-ownership attainment among immigrants and their foreign-born offspring in Canada

    Resource Type:
    Article
    Creator:
    Mendez, Pablo
    Abstract:
    This paper asks whether age at arrival matters when it comes to home-ownership attainment among immigrants, paying particular attention to householders' self-identification as a visible minority. Combining methods that were developed separately in the immigrant housing and the immigrant offspring literatures, this study shows the importance of recognising generational groups based on age at arrival, while also accounting for the interacting effects of current age (or birth cohorts) and arrival cohorts. The paper advocates a (quasi-)longitudinal approach to studying home-ownership attainment among immigrants and their foreign-born offspring. Analysis of data from the Canadian Census reveals that foreign-born householders who immigrated as adults in the 1970s and the 1980s are more likely to be home-owners than their counterparts who immigrated at a younger age when they self-identify as South Asian or White, but not always so when they self-identify as Chinese or as ‘other visible minority’. The same bifurcated pattern recurs between householders who immigrated at secondary-school age and those who were younger upon arrival. Age at arrival therefore emerges as a variable of significance to help explain differences in immigrant housing outcomes, and should be taken into account in future studies of immigrant home-ownership attainment.

    Abstract:
    We address the problem of discovering routes in strongly connected planar geometric networks with directed links. Motivated by the necessity for establishing communication in wireless ad hoc networks in which the only information available to a vertex is its immediate neighborhood, we are considering routing algorithms that use the neighborhood information of a vertex for routing with constant memory only. We solve the problem for three types of directed planar geometric networks: Eulerian (in which every vertex has the same number of incoming and outgoing edges), Outerplanar (in which a single face contains all vertices of the network), and Strongly Face Connected, a new class of geometric networks that we define in the article, consisting of several faces, each face being a strongly connected outerplanar graph.

  • Subterranean Commodification: Informal Housing and the Legalization of Basement Suites in Vancouver from 1928 to 2009

    Resource Type:
    Article
    Creator:
    Quastel, Noah and Mendez, Pablo
    Abstract:
    This article draws on Margaret Radin's theorization of 'contested commodities' to explore the process whereby informal housing becomes formalized while also being shaped by legal regulation. In seeking to move once-informal housing into the domain of official legality, cities can seldom rely on a simple legal framework of private-law principles of property and contract. Instead, they face complex trade-offs between providing basic needs and affordability and meeting public-law norms around living standards, traditional neighbourhood feel and the environment. This article highlights these issues through an examination of the uneven process of legal formalization of basement apartments in Vancouver, Canada. We chose a lengthy period-from 1928 to 2009-to explore how basement apartments became a vital source of housing often at odds with city planning that has long favoured a low-density residential built form. We suggest that Radin's theoretical account makes it possible to link legalization and official market construction with two questions: whether to permit commodification and how to permit commodification. Real-world commodification processes-including legal sanction-reflect hybridization, pragmatic decision making and regulatory compromise. The resolution of questions concerning how to legalize commodification are also intertwined with processes of market expansion.

    Article
    Creator:

    Abstract:
    The new renewable fuels standard (RFS 2) aims to distinguish corn-ethanol that achieves a 20% reduction in greenhouse gas (GHG) emissions compared with gasoline. Field data from Kim et al. (2009) and from our own study suggest that geographic variability in the GHG emissions arising from corn production casts considerable doubt on the approach used in the RFS 2 to measure compliance with the 20% target. If regulators wish to require compliance of fuels with specific GHG emission reduction thresholds, then data from growing biomass should be disaggregated to a level that captures the level of variability in grain corn production and the application of life cycle assessment to biofuels should be modified to capture this variability.

    Abstract:
    One hundred and ten English-speaking children schooled in French were followed from kindergarten to Grade 2 (Mage: T1 = 5;6, T2 = 6;4, T3 = 6;11, T4 = 7;11). The findings provided strong support for the Home Literacy Model (Sénéchal & LeFevre, 2002) because in this sample the home language was independent of the language of instruction. The informal literacy environment at home predicted growth in English receptive vocabulary from kindergarten to Grade 1, whereas parent reports of the formal literacy environment in kindergarten predicted growth in children's English early literacy between kindergarten and Grade 1 and growth in English word reading during Grade 1. Furthermore, 76% of parents adjusted their formal literacy practices according to the reading performance of their child, in support of the presence of a responsive home literacy curriculum among middle-class parents.

    Abstract:
    In this special issue of Nova Religio four historians of medieval and early modern Christianities offer perspectives on basic conceptual frameworks widely employed in new religions studies, including modernization and secularization, radicalism/violent radicalization, and diversity/diversification. Together with a response essay by J. Gordon Melton, these articles suggest strong possibilities for renewed and ongoing conversation between scholars of "old" and "new" religions. Unlike some early discussions, ours is not aimed simply at questioning the distinction between old and new religions itself. Rather, we think such conversation between scholarly fields holds the prospect of productive scholarly surprise and perspectival shifts, especially via the disciplinary practice of historiographical criticism.

  • Polarization-selective grating excitation of plasmons in cylindrical optical fibers

    Resource Type:
    Article
    Creator:
    Albert, Jacques, Dakka, Milad A., Shevchenko, Yanina, and Chen, Chengkun
    Abstract:
    We show that the tilted-grating-assisted excitation of surface plasmon polaritons on gold coated single-mode optical fibers depends strongly on the state of polarization of the core-guided light, even in fibers with cylindrical symmetry. Rotating the linear polarization of the guided light by 90° relative to the grating tilt plane is sufficient to turn the plasmon resonances on and off with more than 17 dB of extinction ratio. By monitoring the amplitude changes of selected individual cladding mode resonances we identify what we believe to be a new refractive index measurement method that is shown to be accurate to better than 5 × 10-5.

  • The role of invented spelling on learning to read in low-phoneme awareness kindergartners: A randomized-control-trial study

    Resource Type:
    Article
    Creator:
    Lever, Rosemary, Ouellette, Gene, Pagan, Stephanie, and Sénéchal, Monique
    Abstract:
    The goal of the present intervention research was to test whether guided invented spelling would facilitate entry into reading for at-risk kindergarten children. The 56 participating children had poor phoneme awareness, and as such, were at risk of having difficulty acquiring reading skills. Children were randomly assigned to one of three training conditions: invented spelling, phoneme segmentation, or storybook reading. All children participated in 16 small group sessions over eight weeks. In addition, children in the three training conditions received letter-knowledge training and worked on the same 40 stimulus words that were created from an array of 14 letters. The findings were clear: on pretest, there were no differences between the three conditions on measures of early literacy and vocabulary, but, after training, invented spelling children learned to read more words than did the other children. As expected, the phoneme-segmentation and invented-spelling children were better on phoneme awareness than were the storybook-reading children. Most interesting, however, both the invented spelling and the phoneme-segmentation children performed similarly on phoneme awareness suggesting that the differential effect on learning to read was not due to phoneme awareness per se. As such, the findings support the view that invented spelling is an exploratory process that involves the integration of phoneme and orthographic representations. With guidance and developmentally appropriate feedback, invented spelling provides a milieu for children to explore the relation between oral language and written symbols that can facilitate their entry in reading.

  • Anomalous permittivity and plasmon resonances of copper nanoparticle conformal coatings on optical fibers

    Resource Type:
    Article
    Creator:
    Shao, Li-Yang, Albert, Jacques, Coyle, Jason P., and Barry, Seán T.
    Abstract:
    The conformal coating of a 50 nm-thick layer of copper nanoparticles deposited with pulse chemical vapor deposition of a copper (I) guanidinate precursor on the cladding of a single mode optical fiber was monitored by using a tilted fiber Bragg grating (TFBG) photo-inscribed in the fiber core. The pulse-per-pulse growth of the copper nanoparticles is readily obtained from the position and amplitudes of resonances in the reflection spectrum of the grating. In particular, we confirm that the real part of the effective complex permittivity of the deposited nano-structured copper layer is an order of magnitude larger than that of a bulk copper film at an optical wavelength of 1550 nm. We further observe a transition in the growth behavior from granular to continuous film (as determined from the complex material permittivity) after approximately 20 pulses (corresponding to an effective thickness of 25 nm). Finally, despite the remaining granularity of the film, the final copper-coated optical fiber is shown to support plasmon waves suitable for sensing, even after the growth of a thin oxide layer on the copper surface.

    Abstract:
    Conventional training simulators commonly use a hexapod configuration to provide motion cues. While widely used, studies have shown that hexapods are incapable of producing the range of motion required to achieve high fidelity simulation required in many applications. A novel alternative is the Atlas motion platform. This paper presents a new generalized kinematic model of the platform which can be applied to any spherical platform actuated by three omnidirectional wheels. In addition, conditions for slip-free and singularity-free motions are identified. Two illustrative examples are given for different omnidirectional wheel configurations.

    Resource Type:
    Article
    Creator:
    Wiener, Michael J. and Van Oorschot, Paul C.
    Abstract:
    A simple new technique of parallelizing methods for solving search problems which seek collisions in pseudorandom walks is presented. This technique can be adapted to a wide range of cryptanalytic problems which can be reduced to finding collisions. General constructions are given showing how to adapt the technique to finding discrete logarithms in cyclic groups, finding meaningful collisions in hash functions, and performing meet-in-the-middle attacks such as a known-plaintext attack on double encryption. The new technique greatly extends the reach of practical attacks, providing the most cost-effective means known to date for defeating: the small subgroup used in certain schemes based on discrete logarithms such as Schnorr, DSA, and elliptic curve cryptosystems; hash functions such as MD5, RIPEMD, SHA-1, MDC-2, and MDC-4; and double encryption and three-key triple encryption. The practical significance of the technique is illustrated by giving the design for three $10 million custom machines which could be built with current technology: one finds elliptic curve logarithms in GF(2155) thereby defeating a proposed elliptic curve cryptosystem in expected time 32 days, the second finds MD5 collisions in expected time 21 days, and the last recovers a double-DES key from two known plaintexts in expected time 4 years, which is four orders of magnitude faster than the conventional meet-in-the-middle attack on double-DES. Based on this attack, double-DES offers only 17 more bits of security than single-DES.

By replacing the visible electrochromic ferrocene with the NIR-absorbing ruthenium complex, the optical attenuation at 1550 nm was enhanced from 19.1 to 30.0 dB and color efficiency also increased from 29.2 to 121.2 cm2/C.

    Creator:
    Bose, Prosenjit, Overmars, M., Wilfong, G., Toussaint, G., Garcia-Lopez, J., Zhu, B., Asberg, B., and Blanco, G.
    Abstract:
    We study the feasibility of design for a layer-deposition manufacturing process called stereolithography which works by controlling a vertical laser beam which when targeted on a photocurable liquid causes the liquid to harden. In order to understand the power as well as the limitations of this manufacturing process better, we define a mathematical model of stereolithography (referred to as vertical stereolithography) and analyze the class of objects that can be constructed under the assumptions of the model. Given an object (modeled as a polygon or a polyhedron), we give algorithms that decide in O(n) time (where n is the number of vertices in the polygon or polyhedron) whether or not the object can be constructed by vertical stereolithography. If the answer is in the affirmative, the algorithm reports a description of all the orientations in which the object can be made. We also show that the objects built with vertical stereolithography are precisely those that can be made with a 3-axis NC machine. We then define a more flexible model that more accurately reflects the actual capabilities of stereolithography (referred to as variable-angle stereolithography) and again study the class of feasible objects for this model. We give an O(n)-time algorithm for polygons and O(n log n)- as well as O(n)-time algorithms for polyhedra. We show that objects formed with variable-angle stereolithography can also be constructed using another manufacturing process known as gravity casting. Furthermore, we show that the polyhedral objects formed by vertical stereolithography are closely related to polyhedral terrains which are important structures in geographic information systems (GIS) and computational geometry. In fact, an object built with variable-angle stereolithography resembles a terrain with overhangs, thus initiating the study of more realistic terrains than the standard ones considered in geographic information systems. Finally, we relate our results to the area of grasping in robotics by showing that the polygonal and polyhedral objects that can be built by vertical stereolithography can be clamped by parallel jaw grippers with any positive-sized gripper.

    Article
    Creator:
    Sack, Jörg-Rüdiger, Maheshwari, Anil, and Lingas, A.
    Abstract:
    We provide optimal parallel solutions to several link-distance problems set in trapezoided rectilinear polygons. All our main parallel algorithms are deterministic and designed to run on the exclusive read exclusive write parallel random access machine (EREW PRAM). Let P be a trapezoided rectilinear simple polygon with n vertices. In O(log n) time using O(n/log n) processors we can optimally compute: 1. Minimum réctilinear link paths, or shortest paths in the L1 metric from any point in P to all vertices of P. 2. Minimum rectilinear link paths from any segment inside P to all vertices of P. 3. The rectilinear window (histogram) partition of P. 4. Both covering radii and vertex intervals for any diagonal of P. 5. A data structure to support rectilinear link-distance queries between any two points in P (queries can be answered optimally in O(log n) time by uniprocessor). Our solution to 5 is based on a new linear-time sequential algorithm for this problem which is also provided here. This improves on the previously best-known sequential algorithm for this problem which used O(n log n) time and space.5 We develop techniques for solving link-distance problems in parallel which are expected to find applications in the design of other parallel computational geometry algorithms. We employ these parallel techniques, for example, to compute (on a CREW PRAM) optimally the link diameter, the link center, and the central diagonal of a rectilinear polygon.

  • Suburban ways of living and the geography of income: How homeownership, single-family dwellings and automobile use define the metropolitan social space

    Resource Type:
    Article
    Creator:
    Moos, Markus and Mendez, Pablo
    Abstract:
    Current research depicts suburbs as becoming more heterogeneous in terms of socio-economic status. Providing a novel analysis, this paper engages with that research by operationalising suburban ways of living (homeownership, single-family dwelling occupancy and automobile use) and relating them to the geography of income across 26 Canadian metropolitan areas. We find that suburban ways of living exist in new areas and remain associated with higher incomes even as older suburbs, as places, have become more diverse. In the largest cities the relationship between income and suburban ways of living is weaker due to the growth of condominiums in downtowns that allow higher income earners to live urban lifestyles. Homeownership is overwhelmingly more important than other variables in explaining the geography of income across 26 metropolitan areas.

  • The relationship between net energy use and the urban density of solar buildings

    Resource Type:
    Article
    Creator:
    Athienitis, Andreas K, Kesik, Ted J, Kennedy, Christopher A, and O'Brien, William
    Abstract:
    There is a paradoxical relationship between the density of solar housing and net household energy use. The amount of solar energy available per person decreases as density increases. At the same time, transportation energy, and to some extent, household operating energy decreases. Thus, an interesting question is posed: how does net energy use vary with housing density? This study attempts to provide insight into this question by examining three housing forms: low-density detached homes, medium-density townhouses, and high-density high-rise apartments in Toronto. The three major quantities of energy that are summed for each are building operational energy use, solar energy availability, and personal transportation energy use. Solar energy availability is determined on the basis of an effective annual collector efficiency. The results show that under the base case in which solar panels are applied to conventional homes, the high-density development uses one-third less energy than the low-density one. Improving the efficiency of the homes results in a similar trend. Only when the personal vehicle fleet or solar collectors are made to be extremely efficient does the trend reverse-the low-density development results in lower net energy.

    Resource Type:
    Article
    Creator:
    Sucharov, Mira
    Abstract:
    This article interrogates the question of what it means to be a scholar-commentator in the digital age. Deploying an autoethnographic style, the essay asks about the role of power and responsibility in teaching, research, and public commentary, particularly in the context of studying and engaging in Jewish politics. The article addresses questions about the proper role of the scholar in the academy and the role of subjectivity and political commitments in structuring scholarship, pedagogy, and public engagement. It also examines how one’s view of the profession can seem to shift through the emergence of new writing outlets and new forums for public engagement. Finally, the author investigates how a scholar’s own political commitments can shift over time, how one seeks to shore up identification on social media while trying to change hearts and minds through the op-ed pages, and how community identification can serve as a buffer and motivator for particular forms of research and political action.

  • Capital Intraconversion' and Canadian Literary Prize Culture

    Resource Type:
    Article
    Creator:
    Mason, Jody
    Abstract:
    This paper analyzes how the “particular symbolic fortunes” of Canada’s most widely recognized literary prize, the Scotiabank Giller Prize, undergo what James English calls “capital intraconversion”––how they are “culturally ‘laundered’” through their association with Frontier College, Canada’s longest-running adult literacy organization. While the Giller initially benefitted from fashioning itself as the private, industry-driven alternative to state-sponsored culture in Canada, increasing criticism of its corporate sponsorship has led, in the past decade, to a rebranding effort. This effort, I contend, seeks to benefit from two key terms––multiculturalism and literacy. Associated as the discourse of multiculturalism and the figure of the literate citizen are with the strong publics of the western, liberal-democratic nation-state, they possess a remarkable ability to accentuate the symbolic capital of Canada’s most widely recognized literary prize.

    Lopina, Olga D., Storey, Kenneth B., Rubstov, Alexander M., and Malysheva, Anna N.
    Abstract:
    Ca-ATPase activity in sarcoplasmic reticulum (SR) membranes isolated from skeletal muscles of the typical hibernator, the ground squirrel Spermophilus undulatus, is about 2-fold lower than that in SR membranes of rats and rabbits and is further decreased 2-fold during hibernation. The use of carbocyanine anionic dye Stains-All has revealed that Ca-binding proteins of SR membranes, histidine-rich Ca-binding protein and sarcalumenin, in ground squirrel, rat, and rabbit SR have different electrophoretic mobility corresponding to apparent molecular masses 165, 155, and 170 kDa and 130, 145, and 160 kDa, respectively; the electrophoretic mobility of calsequestrin (63 kDa) is the same in all preparations. The content of these Ca-binding proteins in SR membranes of the ground squirrels is decreased 3–4 fold and the content of 55, 30, and 22 kDa proteins is significantly increased during hibernation.

  • Plasmon-enhanced refractometry using silver nanowire coatings on tilted fibre Bragg gratings

    Resource Type:
    Article
    Creator:
    Bialiayeu, A., Ianoul, Anatoli, Prezgot, Dan, Bottomley, Adam, and Albert, Jacques
    Abstract:
    A novel technique for increasing the sensitivity of tilted fibre Bragg grating (TFBG) based refractometers is presented. The TFBG sensor was coated with chemically synthesized silver nanowires 100nm in diameter and several micrometres in length. A 3.5-fold increase in sensor sensitivity was obtained relative to the uncoated TFBG sensor. This increase is associated with the excitation of surface plasmons by orthogonally polarized fibre cladding modes at wavelengths near 1.5μm. Refractometric information is extracted from the sensor via the strong polarization dependence of the grating resonances using a Jones matrix analysis of the transmission spectrum of the fibre.

  • The differential impact of social defeat on mice living in isolation or groups in an enriched environment: Plasma corticosterone and monoamine variations

    Resource Type:
    Article
    Creator:
    Anisman, Hymie, Audet, Marie-Claude, McQuaid, Robyn J., and Jacobson-Pick, Shlomit
    Abstract:
    Social defeat in mice is a potent stressor that promotes the development of depressive- and anxiety-like behaviours, as well as variations of neuroendocrine and brain neurotransmitter activity. Although environmental enrichment may protect against some of the adverse behavioural and biological effects of social defeat, it seems that, among male group-housed mice maintained in an enriched environment (EE), aggressive behaviours may be more readily instigated, thus promoting distress and exacerbating psychopathological features. Thus, although an EE can potentially have numerous beneficial effects, these may depend on the general conditions in which mice were raised. It was observed in the current investigations that EE group-housed BALB/cByJ mice displayed increased anxiety-like behaviours compared to their counterparts maintained in a standard environment (SE). Furthermore, in response to social defeat, EE group-housed male mice exhibited decreased weight gain, exaggerated corticosterone elevations and altered hippocampal norepinephrine utilization compared to their SE counterparts. These effects were not apparent in the individually housed EE mice and, in fact, enrichment among these mice appeared to buffer against serotonin changes induced by social defeat. It is possible that some potentially beneficial effects of enrichment were precluded among group-housed mice, possibly owing to social disturbances that might occur in these conditions. In fact, even if social interaction is an essential feature of enrichment, it seems that some of the positive effects of this housing condition might be optimal when mice are housed individually, particularly with regard to buffering the effects of social defeat.

  • Phosphorylation of H,K-ATPase α-subunit in microsomes from rabbit gastric mucosa by cAMP-dependent protein kinase

    Article
    Creator:
    Rubtsov, Alexander M., Petukhov, Sergei P., Murtazina, Dilyara A., Lopina, Olga D., and Storey, Kenneth B.
    Abstract:
    A 100-kDa protein that is a main component of the microsomal fraction from rabbit gastric mucosa is phosphorylated by cAMP-dependent protein kinase (PKA) in the presence of 0.2% Triton X-100. Microsomes from rabbit gastric mucosa possess activity of H,K-ATPase but not activity of Na,K-ATPase. Incubation of microsomes with 5 μM fluorescein 5′-isothiocyanate (FITC) results in both an inhibition of H,K-ATPase and labeling of a protein with an electrophoretic mobility corresponding to the mobility of the protein phosphorylated by PKA. The data suggest that the α-subunit of H,K-ATPase can be a potential target for PKA phosphorylation.

    Lesparre, Nolwenn, Adler, Andy, Komorowski, Jean-Christophe, Grychtol, Bartłomiej, and Gibert, Dominique
    Abstract:
    The electrical resistivity distribution at the base of La Soufrière of Guadeloupe lava dome is reconstructed by using transmission electrical resistivity data obtained by injecting an electrical current between two electrodes located on opposite sides of the volcano. Several pairs of injection electrodes are used in order to constitute a data set spanning the whole range of azimuths, and the electrical potential is measured along a cable covering an angular sector of ≈120? along the basis of the dome. The data are inverted to performa slice electrical resistivity tomography (SERT) with specific functions implemented in the EIDORS open source package dedicated to electrical impedance tomography applied to medicine and geophysics. The resulting image shows the presence of highly conductive regions separated by resistive ridges. The conductive regions correspond to unconsolidated material saturated by hydrothermal fluids. Two of them are associated with partial flank collapses and may represent large reservoirs that could have played an important role during past eruptive events. The resistive ridges may represent massive andesite and are expected to constitute hydraulic barriers.

    Abstract:
    When hydrogen loading is used to enhance the photosensitivity of silica-based optical waveguides and fibres, the presence of molecular hydrogen dissolved in the glass matrix changes the effective index of propagation of guided optical modes by as much as 0.05%. Real-time monitoring of the reflectivity spectrum of Bragg gratings written in such conditions shows that the centre wavelength follows the changes in hydrogen concentration due to diffusion and reaction with glass defects.

    An apodized chirped in-fibre Bragg grating that has a linear dispersion characteristic is reported. The frequency components of an optical pulse (centre wavelength 1551 nm; 10 GHz bandwidth) incident on the grating are reflected with a relative delay that varies linearly from 0 to 130 ps across the spectral width of the pulse. The dispersion compensator is used to correct for the dispersion in a 100 km link (nondispersion shifted fibre) operating at a 10 Gbit/s transmission rate and a wavelength of 1551 nm.

  • A Systematic Approach for Variable Selection With Random Forests: Achieving Stable Variable Importance Values

    Resource Type:
    Article
    Creator:
    Banks, Sarah N., Millard, Koreen, Behnamian, Amir, White, Lori, Richardson, Murray, and Pasher, Jon
    Abstract:
    Random Forests variable importance measures are often used to rank variables by their relevance to a classification problem and subsequently reduce the number of model inputs in high-dimensional data sets, thus increasing computational efficiency. However, as a result of the way that training data and predictor variables are randomly selected for use in constructing each tree and splitting each node, it is also well known that if too few trees are generated, variable importance rankings tend to differ between model runs. In this letter, we characterize the effect of the number of trees (ntree) and class separability on the stability of variable importance rankings and develop a systematic approach to define the number of model runs and/or trees required to achieve stability in variable importance measures. Results demonstrate that both a large ntree for a single model run, or averaged values across multiple model runs with fewer trees, are sufficient for achieving stable mean importance values. While the latter is far more computationally efficient, both the methods tend to lead to the same ranking of variables. Moreover, the optimal number of model runs differs depending on the separability of classes. Recommendations are made to users regarding how to determine the number of model runs and/or trees that are required to achieve stable variable importance rankings.

    The rise of game development and game studies on university campuses prompts academic libraries to consider how to support teaching and research in this area. This article examines current issues and challenges in the development of game collections at academic libraries. The gaming ecosystem has become more complex and libraries may need to move beyond collections largely based on console video games. This article will advance the discussion by considering emerging issues to support access to the full range of games. The article will use examples from Carleton University Library, Ottawa, which has been developing a game collection since 2008.

  • Adaptation and validation of an existing bottom-up model for simulating temporal and inter-dwelling variations of residential appliance and lighting demands

    Resource Type:
    Article
    Creator:
    Beausoleil-Morrison, Ian, Wills, A. D., and Ugursal, V. I.
    Abstract:
    The design and analysis of community-scale energy systems and incentives is a non-trivial task. The challenge of such undertakings is the well-documented uncertainty of building occupant behaviours. This is especially true in the residential sector, where occupants are given more freedom of activity compared to work environments. Further complicating matters is the dearth of available measured data. Building performance simulation tools are one approach to community energy analysis, however such tools often lack realistic models for occupant-driven demands, such as appliance and lighting (AL) loads. For community-scale analysis, such AL models must also be able to capture the temporal and inter-dwelling variation to achieve realistic estimates of aggregate electrical demand. This work adapts the existing Centre for Renewable Energy Systems Technology (CREST) residential energy model to simulate Canadian residential AL demands. The focus of the analysis is to determine if the daily, seasonal, and inter-dwelling variation of AL demands estimated by the CREST model is realistic. An in-sample validation is conducted on the model using 22 high-resolution measured AL demand profiles from dwellings located in Ottawa, Canada. The adapted CREST model is shown to broadly capture the variation of AL demand variations observed in the measured data, however seasonal variation in daily AL demand behaviour was found to be under-estimated by the model. The average and variance of daily load factors was found to be similar between measured and modelled. The model was found to under-predict the daily coincidence factors of aggregated demands, although the variance of coincident factors was shown to be similar between measured and modelled. A stochastic baseload input developed for this work was found to improve estimates of the magnitude and variation of both baseload and peak demands.

  • Continuous approximate synthesis of planar function-generators minimising the design error

    Resource Type:
    Article
    Creator:
    Guigue, Alexis and Hayes, M. John
    Abstract:
    It has been observed in the literature that as the cardinality of the prescribed discrete input-output data set increases, the corresponding four-bar linkages that minimise the Euclidean norm of the design and structural errors tend to converge to the same linkage. The important implication is that minimising the Euclidean norm, or any p-norm, of the structural error, which leads to a nonlinear least-squares problem requiring iterative solutions, can be accomplished implicitly by minimising that of the design error, which leads to a linear least-squares problem that can be solved directly. Apropos, the goal of this paper is to take the first step towards proving that as the cardinality of the data set tends towards infinity the observation is indeed true. In this paper we will integrate the synthesis equations in the range between minimum and maximum input values, thereby reposing the discrete approximate synthesis problem as a continuous one. Moreover, we will prove that a lower bound of the Euclidean norm, and indeed of any p-norm, of the design error for planar RRRR function-generating linkages exists and is attained with continuous approximate synthesis.

  • An information driven hybrid evolutionary algorithm for optimal design of a Net Zero Energy House

    Resource Type:
    Article
    Creator:
    Bucking, Scott, Zmeureanu, Radu, and Athienitis, Andreas
    Abstract:
    Building Performance Simulation (BPS) is a powerful tool to estimate and reduce building energy consumption at the design stage. However, the true potential of BPS remains unrealized if trial and error simulation methods are practiced to identify combinations of parameters to reduce energy use of design alternatives. Optimization algorithms coupled with BPS is a process-orientated tool which identifies optimal building configurations using conflicting performance indicators. However, the application of optimization approaches to building design is not common practice due to time and computation requirements. This paper proposes a hybrid evolutionary algorithm which uses information gained during previous simulations to expedite and improve algorithm convergence using targeted deterministic searches. This technique is applied to a net-zero energy home case study to optimize trade-offs in passive solar gains and active solar generation using a cost constraint.

  • Discussing stories: On how a dialogic reading intervention improves kindergartners' oral narrative construction

    Resource Type:
    Article
    Creator:
    Sénéchal, Monique and Lever, Rosemary
    Abstract:
    Oral narrative skills are assumed to develop through parent-child interactive routines. One such routine is shared reading. A causal link between shared reading and narrative knowledge, however, has not been clearly established. The present research tested whether an 8-week shared-reading intervention enhanced the fictional narrative skills of children entering formal education. Dialogic reading, a shared reading activity that involves elaborative questioning techniques, was used to engage children in oral interaction during reading and to emphasize elements of story knowledge. Forty English-speaking five- and six-year-olds were assigned to either the dialogic-reading or an alternative-treatment group. ANCOVA results found that the dialogic-reading children’s post-test narratives were significantly better on structure and context measures than those for the alternative-treatment children, but results differed for produced or retold narratives. The dialogic-reading children also showed expressive vocabulary gains. Overall, this study concretely determined that aspects of fictional narrative construction knowledge can be learned from interactive book reading.
