Intersectional insights and frameworks are put into practice in a multitude of highly contested, complex, and unpredictable ways. We group such engagements with intersectionality into three loosely defined sets of practices: applications of an intersectional framework or investigations of intersectional dynamics; debates about the scope and content of intersectionality as a theoretical and methodological paradigm; and political interventions employing an intersectional lens. We propose a template for fusing these three levels of engagement with intersectionality into a field of intersectional studies that emphasizes collaboration and literacy rather than unity. Our objective here is not to offer pat resolutions to all questions about intersectional approaches but to spark further inquiry into the dynamics of intersectionality both as an academic frame and as a practical intervention in a world characterized by extreme inequalities. At the same time, we wish to zero in on some issues that we believe have occupied a privileged place in the field from the very start, as well as on key questions that will define the field in the future. To that end, we foreground the social dynamics and relations that constitute subjects, displacing what often seems like an undue emphasis on the subjects (and categories) themselves as the starting point of inquiry. We also situate the development and contestation of these focal points of intersectional studies within the politics of academic and social movements — which, we argue, are themselves deeply intersectional in nature and therefore must continually be interrogated as part of the intersectional project.

Secret sharing is a procedure for splitting a message into several parts so that no subset of parts is sufficient to read the message, but the entire set is. We show how this procedure can be implemented using Greenberger-Horne-Zeilinger (GHZ) states. In the quantum case the presence of an eavesdropper will introduce errors so that his presence can be detected. We also show how GHZ states can be used to split quantum information into two parts so that both parts are necessary to reconstruct the original qubit.

Is economic development conducive to political democracy? Does democracy foster or hinder material welfare? These two questions are examined by looking at the experience of 135 countries between 1950 and 1990. Descriptive information, statistical analyses, and historical narratives are interwoven to gain an understanding of the dynamic of political regimes and their impact on economic development and other aspects of material welfare. The findings, several most surprising, dispel any notion of a trade-off between democracy and development. Economic development does not generate democracies but democracies are much more likely to survive in wealthy societies. Political regimes have no impact on the growth of total national incomes, while political instability affects growth only in dictatorships. Per capita incomes grow faster in democracies since population increases faster under dictatorships. In general, political regimes have more of an effect on demography than on economics

Using social practice theory, this article reveals the process of collective value creation within brand communities. Moving beyond a single case study, the authors examine previously published research in conjunction with data collected in nine brand communities comprising a variety of product categories, and they identify a common set of value-creating practices. Practices have an “anatomy” consisting of (1) general procedural understandings and rules (explicit, discursive knowledge); (2) skills, abilities, and culturally appropriate consumption projects (tacit, embedded knowledge or how-to); and (3) emotional commitments expressed through actions and representations. The authors find that there are 12 common practices across brand communities, organized by four thematic aggregates, through which consumers realize value beyond that which the firm creates or anticipates. They also find that practices have a physiology, interact with one another, function like apprenticeships, endow participants with cultural capital, produce a repertoire for insider sharing, generate consumption opportunities, evince brand community vitality, and create value. Theoretical and managerial implications are offered with specific suggestions for building and nurturing brand community and enhancing collaborative value creation between and among consumers and firms.

As more and more marketers incorporate social media as an integral part of the promotional mix, rigorous investigation of the determinants that impact consumers’ engagement in eWOM via social networks is becoming critical. Given the social and communal characteristics of social networking sites (SNSs) such as Facebook, MySpace and Friendster, this study examines how social relationship factors relate to eWOM transmitted via online social websites. Specifically, a conceptual model that identifies tie strength, homophily, trust, normative and informational interpersonal influence as an important antecedent to eWOM behaviour in SNSs was developed and tested. The results confirm that tie strength, trust, normative and informational influence are positively associated with users’ overall eWOM behaviour, whereas a negative relationship was found with regard to homophily. This study suggests that product-focused eWOM in SNSs is a unique phenomenon with important social implications. The implications for researchers, practitioners and policy makers of social media regulation are discussed.

One of the most conspicuous behavioral effects produced by surgical rotation of the eyeball through 180 degrees is the forced circling or spontaneous optokinetic reaction. Animals with inverted vision caused by eye rotation tend to turn continuously in circles (4, 6, 8). In fishes and amphibians this circling may persist indefinitely with little or no correction by reeducation. Similar circus movement is caused by contralateral transplantation of the eyeball with inversion on only one axis and also by cross-connection of the optic nerves to the wrong side of the brain (7). In all these situations movement on the part of the animal causes the visual image to pass over the retinal field or its central projection in a direction opposite to normal. The forced circling phenomenon of inverted vision is an illustration of the importance of kinesthetic effects in visual perception. Under normal conditions the image of the visual field, whether it be stationary or moving across the retina, can be perceived as being either in motion or at rest depending upon whether the perceiving animal is moving or at rest. The apparent position and direction of motion of the visual field depend upon the posture

The purpose of this study was to test a model of the organizational innovation process that suggests that the strategy-structure causal sequence is differentiated by radical versus incremental innovation. That is, unique strategy and structure will be required for radical innovation, especially process adoption, while more traditional strategy and structure arrangements tend to support new product introduction and incremental process adoption. This differentiated theory is strongly supported by data from the food processing industry. Specifically, radical process and packaging adoption are significantly promoted by an aggressive technology policy and the concentration of technical specialists. Incremental process adoption and new product introduction tends to be promoted in large, complex, decentralized organizations that have market dominated growth strategies. Findings also suggest that more traditional structural arrangements might be used for radical change initiation if the general tendencies that occur in these dimensions as a result of increasing size can be delayed, briefly modified, or if the organization can be partitioned structurally for radical vs. incremental innovation. In particular, centralization of decision making appears to be necessary for radical process adoption along with the movement away from complexity toward more organizational generalists. This suggests that a greater support of top managers in the innovation process is necessary to initiate and sustain radical departures from the past for that organization.

Stenotrophomonas maltophilia is an emerging multidrug-resistant global opportunistic pathogen. The increasing incidence of nosocomial and community-acquired S. maltophilia infections is of particular concern for immunocompromised individuals, as this bacterial pathogen is associated with a significant fatality/case ratio. S. maltophilia is an environmental bacterium found in aqueous habitats, including plant rhizospheres, animals, foods, and water sources. Infections of S. maltophilia can occur in a range of organs and tissues; the organism is commonly found in respiratory tract infections. This review summarizes the current literature and presents S. maltophilia as an organism with various molecular mechanisms used for colonization and infection. S. maltophilia can be recovered from polymicrobial infections, most notably from the respiratory tract of cystic fibrosis patients, as a cocolonizer with Pseudomonas aeruginosa. Recent evidence of cell-cell communication between these pathogens has implications for the development of novel pharmacological therapies. Animal models of S. maltophilia infection have provided useful information about the type of host immune response induced by this opportunistic pathogen. Current and emerging treatments for patients infected with S. maltophilia are discussed.

Context‐aware recommender systems (CARS) generate more relevant recommendations by adapting them to the specific contextual situation of the user. This article explores how contextual information can be used to create intelligent and useful recommender systems. It provides an overview of the multifaceted notion of context, discusses several approaches for incorporating contextual information in the recommendation process, and illustrates the usage of such approaches in several application areas where different types of contexts are exploited. The article concludes by discussing the challenges and future research directions for context‐aware recommender systems.

Senior executives are thought to provide the organization’s ethical ‘tone at the top’. We conducted an inductive interview-based study aimed at defining the perceived content domain of executive ethical leadership. We interviewed two types of key informants - corporate ethics officers and senior executives - about executive ethical leadership and then a contrasting category we labeled ‘ethically neutral’ leadership. Systematic analysis of the data identified multiple dimensions of ethical and ethically neutral leadership. The findings suggest that ethical leadership is more than traits such as integrity and more than values-based inspirational leadership. It includes an overlooked transactional component that involves using communication and the reward system to guide ethical behavior. Similarities and differences between ethics officers’ and senior executives’ perceptions also led to insights about the importance of vantage point and social salience in perceptions of executive ethical leadership. In order to be perceived as an ethical leader by those outside the executive suite, the executive must engage in socially salient behaviors that make the executive stand out as an ethical figure against an ethically neutral ground.

We estimate the importance of teachers in Chicago public high schools using matched student-teacher administrative data. A one standard deviation, one semester improvement in math teacher quality raises student math scores by 0.13 grade equivalents or, over 1 year, roughly one-fifth of average yearly gains. Estimates are relatively stable over time, reasonably impervious to a variety of conditioning variables, and do not appear to be driven by classroom sorting or selective score reporting. Also, teacher quality is particularly important for lower-ability students. Finally, traditional human capital measures—including those determining compensation—explain little of the variation in estimated quality.

This study addresses the issue of whether positive employee attitudes and behaviors influence business outcomes or whether positive business outcomes influence positive employee attitudes and behaviors. We hypothesize that employee satisfaction, organizational citizenship behavior, and employee turnover influence profitability and customer satisfaction. Data were gathered from the units of a regional restaurant chain via employee surveys, manager surveys, customer surveys, and organizational records. Cross‐lagged regression analyses show that employee attitudes and behaviors at Time 1 are related to organizational effectiveness at Time 2. Additional cross‐lagged regression analyses show no significant relationship between organizational effectiveness at Time 1 and the employee attitudes and behaviors at Time 2. These results add to the evidence that HR outcomes influence business outcomes, rather than the other way around.

The ease and speed with which business transactions can be carried out over the Web have been a key driving force in the rapid growth of electronic commerce. Business-to-business e-commerce is the focus of much attention today, mainly due to its huge volume. While there are certainly gains to be made in this arena, most of it is the implementation of much more efficient supply management, payments, etc. On the

This study sought to unify the team composition literature by using meta-analytic techniques to estimate the relationships between specified deep-level team composition variables (i.e., personality factors, values, abilities) and team performance. The strength of the team composition variable and team performance relationships was moderated by the study setting (lab or field) and the operationalization of the team composition variable. In lab settings, team minimum and maximum general mental ability and team mean emotional intelligence were related to team performance. Only negligible effects were observed in lab settings for the personality factor and team performance relationships, as well as the value and team performance relationships. In contrast, team minimum agreeableness and team mean conscientiousness, openness to experience, collectivism, and preference for teamwork emerged as strong predictors of team performance in field studies. Results can be used to effectively compose teams in organizations and guide future team composition research.

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper presents a comparison study between 10 automatic and six interactive methods for liver segmentation from contrast-enhanced CT images. It is based on results from the “MICCAI 2007 Grand Challenge” workshop, where 16 teams evaluated their algorithms on a common database. A collection of 20 clinical images with reference segmentations was provided to train and tune algorithms in advance. Participants were also allowed to use additional proprietary training data for that purpose. All teams then had to apply their methods to 10 test datasets and submit the obtained results. Employed algorithms include statistical shape models, atlas registration, level-sets, graph-cuts and rule-based systems. All results were compared to reference segmentations five error measures that highlight different aspects of segmentation accuracy. All measures were combined according to a specific scoring system relating the obtained values to human expert variability. In general, interactive methods reached higher average scores than automatic approaches and featured a better consistency of segmentation quality. However, the best automatic methods (mainly based on statistical shape models with some additional free deformation) could compete well on the majority of test images. The study provides an insight in performance of different segmentation approaches under real-world conditions and highlights achievements and limitations of current image analysis techniques. </para>

This research explores the grassroots brand community centered on the Apple Newton, a product that was abandoned by the marketer. Supernatural, religious, and magical motifs are common in the narratives of the Newton community, including the miraculous performance and survival of the brand, as well as the return of the brand creator. These motifs invest the brand with powerful meanings and perpetuate the brand and the community, its values, and its beliefs. These motifs also reflect and facilitate the many transformative and emancipatory aspects of consuming this brand. Our findings reveal important properties of brand communities and, at a deeper level, speak to the communal nature of religion and the enduring human need for religious affiliation.

This study evaluates the effectiveness of augmented reality (AR) as an e-commerce tool using two products — sunglasses and watches. Study 1 explores the effectiveness of AR by comparing it to a conventional website. The results show that AR provides effective communication benefits by generating greater novelty, immersion, enjoyment, and usefulness, resulting in positive attitudes toward medium and purchase intention, compared to the web-based product presentations. Study 2 compares the paths by which consumers evaluate products through AR versus web with a focus on interactivity and vividness. It is revealed that immersion mediates the relationship between interactivity/vividness and two outcome variables — usefulness and enjoyment in the AR condition compared to the web condition where no significant paths between interactivity and immersion and between previous media experience and media novelty are found. Participants’ subjective opinions about AR are examined through opinion mining to better understand consumer responses to AR.

The authors revisited the demographic diversity variable and team performance relationship using meta-analysis and took a significant departure from previous meta-analyses by focusing on specific demographic variables (e.g., functional background, organizational tenure) rather than broad categories (e.g., highly job related, less job related). They integrated different conceptualizations of diversity (i.e., separation, variety, disparity) into the development of their rationale and hypotheses for specific demographic diversity variable—team performance relationships. Furthermore, they contrasted diversity with the team mean on continuous demographic variables when elevated levels of a variable, as opposed to differences, were more logically related to team performance. Functional background variety diversity had a small positive relationship with general team performance as well as with team creativity and innovation. The relationship was strongest for design and product development teams. Educational background variety diversity was related to team creativity and innovation and to team performance for top management teams. Other variables generally thought to increase task-relevant knowledge (e.g., organizational tenure) and team performance were unrelated to team performance, although these variables were almost never studied as the variety conceptualization (i.e., the conceptualization that can reflect the breadth of knowledge that can be applied to the task). Team mean organizational tenure was related to team performance in terms of efficiency. Race and sex variety diversity had small negative relationships with team performance, whereas age diversity was unrelated to team performance regardless of diversity conceptualization. Implications for staffing teams and future research are discussed.
