MOOsburg is a community‐oriented multi‐user domain. It was created to enrich the Blacksburg Electronic Village by providing real‐time, situated, interaction, and a place‐based information model for community information. We are experimenting with an implementation fundamentally different from classic multi‐user domains object‐oriented (MOOs), supporting distributed system development and management, and a direct manipulation approach to navigation. To guide the development of MOOsburg, we are focusing on a set of community‐oriented applications, including a virtual science fair.

Through systematic observation of police decision-making behavior, the aim of this paper is to investigate what factors differentiate between citizens who receive a warning vs a ticket from police and whether the influence of those factors varies by race. The paper also explores the context of those decisions for both blacks and whites to further the understanding of the underlying mechanisms of any observed differences in the likelihood of receiving a ticket vs a warning.

Data were collected during police ridealongs conducted in a sample of cities within Cuyahoga County, Ohio. A total of 140 ridealongs were completed, yielding a total of 312 vehicle or citizen stops.

The paper finds that black citizens are more likely to receive a ticket than white citizens. However, the paper also finds important differences in the situational context of traffic stops for blacks and whites and uncover evidence of a cycle of traffic tickets and license suspensions among some black drivers.

The study demonstrates the importance of examining the underlying situational context in analyses of decision making in traffic stops. The main limitation of the analyses is that the data were limited to one county in the state of Ohio.

The data suggests that one of the causes of the racial disparities in tickets vs warnings involves a cycle of tickets and license suspensions that occurs among some black drivers. These drivers appear to become caught up in a cycle where a compilation of prior tickets from traffic infractions, driving without insurance, or defaulting on child support payments leads to high numbers of points and subsequent license suspensions. The paper discusses some practical implications for addressing this pattern, including specific programs that could be adopted by municipalities that seek to break the cycle of repeated violation of driver's license laws.

Beyond identifying the impact of citizen race on the likelihood of receiving a warning vs a ticket during a traffic stop, this study contributes to the existing literature by exploring the situational context of these decisions, and identifying the ways in which variations in situational contexts help explain racial differences in outcomes in traffic stops. The identification of a traffic ticket cycle among some black drivers appears to be an original finding.

Baby boomers (people born between 1946 and 1964) are approaching retirement and there is concern about their preparation for their future health and wellbeing. Food shopping is likely to play a major role in their future lives. The purpose of this paper is to examine their reasons for choosing to buy food from particular shops and whether demographic characteristics and health status were associated with them.

A questionnaire survey was conducted among a random sample of 1,037 people aged between 40 and 71 years in Victoria, Australia. Respondents were asked to indicate, from a list, their reasons for choosing to shop at particular food outlets. Regression analysis was used to examine the relationships between respondents' demographics and health status and their reasons for shopping at the food stores.

Multivariate analysis showed that the reasons the respondents reported in choosing shops fell into four groups: saving, convenience, quality and healthy foods, and user‐friendly environment. Saving was negatively related to income, age, level of education and also linked with country of birth, religious affiliation, and marital status. Convenience was negatively associated with age and also related to health status and religious affiliation. Quality/healthy food products were positively related to age but negatively associated with body mass index, and also linked to country of birth. User‐friendly environment was negatively associated with income and education and related to gender and religious affiliation.

The paper's results show that stores could provide more information, perhaps as signage, to their recycling and health information facilities, particularly in low socio‐economic status areas. Furthermore, the social status and religious associations confirm the view that shopping reflects broad societal affiliations among baby boomers. Shopping centres can be used to provide support for health and environmental sustainability promotions.

Using the remarkable olfaction ability, insects can sense trace amounts of host plant volatiles that are notorious for causing severe damage to fruits and vegetables and in consequence the industry. The purpose of the paper is to investigate the interactions between olfactory proteins, odorant-binding proteins (OBPs) and host plant volatiles through the developed olfactory biosensors. It might be helpful to develop novel pest control strategies.

Using the successfully expressed and purified OBPs of the oriental fruit fly Bactrocera dorsalis, a biosensor was developed by immobilizing the proteins on interdigitated electrodes through nitrocellulose membrane. Based on electrochemical impedance sensing, benzaldehyde emitted by the host plants, such as Beta vulgaris, was detected, which could be used to investigate and analyze the mechanisms of pests’ sense of chemical signals. The relative decreases of charge transfer resistances of the sensor were proportional to the odorant concentrations from 10⁻⁷ M to 10⁻³ M. Meanwhile, the interactions between OBPs and benzaldehyde were studied through the process of molecular docking.

The paper provides a pest OBPs-based biosensor that could sensitively detect the host odorants benzaldehyde. Meanwhile, the most related amino acids of OBPs that bind to host plant volatiles can be distinguished with molecular docking.

An olfactory biosensor was developed to explore interactions and mechanism between the pest OBPs and benzaldehyde, which showed promising potentials for small organic molecule sensing. Simultaneously, it might be helpful for novel pest control strategies.

Empirical research provides evidence that green supply chain management (SCM) practices positively impact firm performance. Yet, questions remain regarding how firms configure their organizations and design green practices to achieve improved performance, especially in light of a constantly changing business environment. This research uses the resource-based and strategic choice theories to better understand the antecedent roles of two strategic orientations, supply chain orientation (SCO) and environmental orientation (EO), on both the implementation and outcomes of green SCM practices. The paper aims to discuss these issues.

Survey responses from 367 supply chain managers are tested through structural equation modeling.

Findings suggest that a combination of SCO and EO capabilities positively influence the implementation of green SCM practices, and positively impact firm performance. Results also suggest that the capability bundle of SCO, EO, and green SCM should be adaptable to the changing business environment.

This research contributes through the combination of the resource-based theory, supported by strategic choice theory, to better understand how managers configure and re-configure valuable green-related capabilities to adapt to the constantly changing business environment.

PhD graduates are entering an increasing range of careers, but past research has highlighted a lack of preparation for these careers. This study aims to explore the reflections of PhD graduates from science and humanities and social science disciplines regarding support for career development (CD) during their study.

The authors used an explanatory sequential mixed-methods design and collected 136 survey responses and interviewed 21 PhD graduates from two US and one New Zealand universities to investigate their career readiness. Using the lens of Cognitive Information Processing theory, the authors explored the development of self-knowledge and career options-knowledge, and how support at the macro (institutional), meso (departmental) and micro (supervisors) levels influenced CD.

During doctoral study, there was very poor engagement with CD activities. Graduates displayed limited self-knowledge and poor knowledge about career options. Graduates reported drawing mainly on their departments and supervisors for career guidance. Although there were pockets of good practice, some departments were perceived as promoting academia as the only successful outcome, neglecting to support other possible pathways. Some graduates reported excellent supervisor support for CD, but others described disinterest or a damaging response if students said they were not wanting to pursue academia.

The enabling aspects for developing self- and options-knowledge are collated into a conceptual model, which identifies key factors at institutional, departmental and supervisor levels, as well as for PhD students themselves.

This study examines the use of dark humor in brand-to-brand communications on social media and its impact on consumers' brand perceptions. In particular, this study looks at roasting messages in which a brand humorously insults its peers.

The authors used a sampling method to recruit 286 participants from the United States. They employed an ANOVA and Tukey's post hoc analysis to test the hypotheses, as well as Hayes' PROCESS to test the mediation and moderation effects, including Johnson–Neyman procedure.

The authors found that not all customers find roasting messages funny. Rather, consumers' personality and age will influence their perceived humor of the messages and their brand evaluations. Customers who are young and extroverted are likely to believe roasting messages to be funny. They thus perceive the brand to be cooler and more sincere when using such a communication approach, compared to when the brand neutrally interacts with others. Meanwhile, brands may find less success with old and introverted customers.

This research sheds light on how the consumers' perception of humor in a roasting type of brand-to-brand communication has an impact on consumers' psychological perceptions of brand coolness and brand sincerity. To guide practitioners, it explored how the interaction between a consumer's personality and age moderates the aforementioned relationship.

The purpose of this paper is to examine the relationship between and corporate environmental responsibility (CER) and audit risk.

A survey participation request was mailed to 5,008 US auditors at random. The request provided a link to an electronic survey. The final sample consists of anonymous responses from 163 auditors.

The authors find that auditors, on average, do not perceive a significant relationship between corporate environmental strengths and audit risk; however, they do perceive an increase in audit risk among firms with corporate environmental concerns. Use of CER in the risk assessment process also varies across types of CER: 15 per cent of auditors use corporate environmental strengths to assess audit risk, while 43 per cent of auditors use corporate environmental concerns to assess audit risk. Perception of the CER/audit risk relationship is a significant determinant of CER use. Finally, both types of CER are found to have average usefulness in the risk assessment process.

The findings are limited to US auditors; results may not be transferable to other countries.

Studies involving the impact of CER on earnings generally involve archival data. By examining the impact of CER on audit risk, using a unique dataset, the authors present a different and timely setting to study the CER/earnings relationship. To the best of the authors' knowledge, this is the first paper to document the relationship between CER and audit risk.

The purpose of this paper is to examine: gender differences in the choice to perform challenging tasks, gender differences in the actual performance of challenging tasks, and the impact of challenging experiences on supervisors' evaluations of individuals' potential for career advancement.

In study 1, a sample of 158 students participated in a laboratory study that examined gender differences in choosing to perform challenging tasks in a situation that stressed individual performance. In study 2, a sample of 93 interns completed questionnaires in which the authors measured their challenging job experiences. Interns' supervisors evaluated interns' potential for career advancement.

In an achievement situation, women chose to perform fewer challenging tasks than men (study 1). During their internships, females had fewer challenging job experiences than males (study 2). Having challenging experiences was positively related to supervisors' evaluations of interns' potential for career advancement (study 2).

The use of student samples may be considered a limitation of these studies. However, the nature of the research questions justifies an initial examination among students. Moreover, small gender differences in experiences at the start of individuals' careers may ultimately lead to increasing discrepancies between men's and women's careers.

The study is the first to examine individuals' own impact on the extent to which they experience job challenge. Moreover, it is the first that empirically examines the relationship between job challenge and evaluations of career potential.
