Associations of children's perceived neighborhood environments with walking and physical activity

Purpose. To examine associations between children's perceptions of the neighborhood environment and walking and physical activity.
Design. Cross-sectional study of a school-based sample.
Setting. Elementary schools in Melbourne, Australia.
Subjects. 280 children aged 10 years (response rate 78%).
Measures. A self-report survey assessed children's perceptions of the neighborhood physical and social environments and their weekly walking frequency. Physical activity was also objectively measured using accelerometers.
Results. Multiple linear regression analyses showed a positive association between walking frequency and the number of accessible destinations in the neighborhood among boys; having a neighborhood that was easy to walk/cycle around and perceiving lots of graffiti were positively associated with walking frequency among girls. Perceiving lots of litter and rubbish was positively associated with boys' overall physical activity, but no environmental variables were associated with girls' overall physical activity.
Conclusion. Several different environmental factors were associated with walking and physical activity. Perceptions of the neighborhood environment were more strongly associated with girls' walking than with objectively-measured physical activity. Future studies should confirm these findings using objective measures and prospective study designs.

Latent variable models of need for uniqueness

The theory of uniqueness has been invoked to explain attitudinal and behavioral nonconformity with respect to peer-group, social-cultural, and statistical norms, as well as the development of a distinctive view of self via seeking novelty goods, adopting new products, acquiring scarce commodities, and amassing material possessions. Present research endeavors in psychology and consumer behavior are inhibited by uncertainty regarding the psychometric properties of the Need for Uniqueness Scale, the primary instrument for measuring individual differences in uniqueness motivation. In an important step toward facilitating research on uniqueness motivation, we used confirmatory factor analysis to evaluate three a priori latent variable models of responses to the Need for Uniqueness Scale. Among the a priori models, an oblique three-factor model best accounted for commonality among items. Exploratory factor analysis followed by estimation of unrestricted three- and four-factor models revealed that a model with a complex pattern of loadings on four modestly correlated factors may best explain the latent structure of the Need for Uniqueness Scale. Additional analyses evaluated the associations among the three a priori factors and an array of individual differences. Results of those analyses indicated the need to distinguish among facets of the uniqueness motive in behavioral research.

Corticomotor responses to attentionally demanding motor performance: a mini-review

Increased attentional demand has been shown to reduce motor performance, leading to increases in accidents, particularly in elderly populations. While these deficits have been well documented behaviorally, their cortical correlates are less well known. Increased attention has been shown to affect activity in prefrontal regions of the cortex. However there have been varying results within past research investigating corticomotor regions, mediating motor performance. This mini-review initially discusses past behavioral research, before moving to studies investigating corticomotor areas in response to changes in attention. Recent dual task studies have revealed a possible decline in the ability of older, but not younger, adults to activate inhibitory processes within the motor cortex, which may be correlated with poor motor performance, and thus accidents. A reduction in cortical inhibition may be caused by neurodegeneration within prefrontal regions of the cortex with age, rendering older adults less able to allocate attention to corticomotor regions.

Behavioral characteristics of men accused of rape: evidence for different types of rapists

The aim of this study was to determine whether the behavioral characteristics demonstrated by rapists clustered together into groups that were similar to the common rapist typology in the literature: anger, power exploitative, power reassurance, and sadistic. Two studies were conducted to examine the evidence for this typology. Study 1 involved the analysis of data from 130 men charged with sexual assault and Study 2 involved the analysis of court transcripts from 50 rape cases tried through the court system. The results of Study 1 revealed that there was some validity to the characteristics usually associated with each of the four types of rape, especially for the power reassurance and sadistic rapists. However, there were some unexpected outliers within both the anger and power exploitative types of rapists, which may suggest that there is more than one type of anger rapist and more than two types of power rapists. The results of Study 2 very closely replicated the results of Study 1. Future research needs to focus on the behavioral, motivational, and cognitive characteristics associated with each of the types of rapists and research them separately, so that it is possible to further evaluate the evidence for the typology identified in this study.

Behavioral adaptation within cross-cultural virtual teams

With today's business environments no longer confined to national borders, much work is undertaken in global virtual teams. Such teams consist of members located in different countries that communicate via technology media to complete a project task. Much of the research in this area has been focused on the technological aspects of such environments; there is, however, a lack of research into the behavioral aspects and the issue of cultural differences in particular. It has been acknowledged that when cultural diversity is neither recognized nor acted upon, significant challenges can arise for the team. Current advice in the literature suggests that team members should adapt their normal working behavior in consideration of cultural differences. However, there is little indication of how team members should do so. This study investigated if and/or how team members adapt their behavior in cross-cultural virtual teams. The results of this study indicate that team members can adapt their behavior in both spoken and written communication as well as allowing for religious beliefs and time zone differences. This paper discusses specifically how behavior can be adapted, including a discussion of behaviors that caused concern. Finally, a framework of behavioral adaptations is presented for ways to improve cross-cultural virtual team interactions.

Testing the factor structure of the behavioral-intentions battery: an empirical study of the Australian banking industry

The five-factor ‘Behavioural-Intentions Battery’ was developed by Zeithaml, Berry and Parasuraman (1996), to measure customer behavioural and attitudinal intentions. The structure of this model was re-examined by Bloomer, de Ruyter and Wetzels (1999) across different service industries. They concluded that service loyalty is a multi dimensional construct consisting of four, not five, distinct dimensions. To date, neither model has been tested within a banking environment. This research independently tested the ‘goodness of fit’ of both the four and five-factor models, to data collected from branch bank customers. Data were collected via questionnaire with a sample of 348 banking customers. A confirmatory factor analysis was conducted upon the two opposing factor structures, revealing that the five-factor structure has a superior model fit; however, the fit is ‘marginal’.

Effectiveness of staff training programs for behavioral problems among older people with dementia

This paper reviewed studies on staff training programs to address the behavioral problems associated with dementia among older people in residential care. The papers were classified according to whether or not the studies included a control group in the research design. The results of the review demonstrate that there has been a wide range of psychosocial and educational interventions to reduce behavioral problems among older people with dementia, with inconsistent results being obtained. However, many of these studies suffer from problems in their research design that make it difficult to evaluate their effectiveness. Problems in conducting research in the nursing home setting are highlighted, and suggestions for future research in this area are discussed.

Reasons why dissatisfied customers exhibit behavioral loyalty

The development of supplier loyalty and its potential application to the business-to-business settings has not been widely explored. Day (1969) cautions that loyalty viewed in terms of purchase decisions may not distinguish between loyalty and spurious loyalty. This study follows the composite loyalty approach providing both behavioral aspects (purchase intentions) and attitudinal loyalty in order to fully explain the concept of supplier loyalty. This framework has not been previously applied in the B2B literature.The objective of this research is to identify reasons why B2B customers do not show consistency between attitudinal and behavioral loyalty and why dissatisfied customers do not switch suppliers. A survey was conducted during 2006 with a sample of executives from 240 SME companies in a large Asian city. A range of measures was obtained including attitudinal loyalty, behavioral loyalty, satisfaction and open ended responses on nature of current problems. Following Dick and Basu (1994), customers are classified into loyalty groups. Customers having high and low attitudinal loyalty are compared on satisfaction, switching attitudes and problems within the relationship. Constraints to switching by the dissatisfied customers are discussed. A profile of the "Spurious Loyal" customer is provided. This study seeks to better understand the nature of dissatisfaction and loyalty within these long term focal relationships.

Changing philosophies and tools for statistical inferences in behavioral ecology

Recent developments in ecological statistics have reached behavioral ecology, and an increasing number of studies now apply analytical tools that incorporate alternatives to the conventional null hypothesis testing based on significance levels. However, these approaches continue to receive mixed support in our field. Because our statistical choices can influence research design and the interpretation of data, there is a compelling case for reaching consensus on statistical philosophy and practice. Here, we provide a brief overview of the recently proposed approaches and open an online forum for future discussion (https://bestat.ecoinformatics.org/). From the perspective of practicing behavioral ecologists relying on either correlative or experimental data, we review the most relevant features of information theoretic approaches, Bayesian inference, and effect size statistics. We also discuss concerns about data quality, missing data, and repeatability. We emphasize the necessity of moving away from a heavy reliance on statistical significance while focusing attention on biological relevance and effect sizes, with the recognition that uncertainty is an inherent feature of biological data. Furthermore, we point to the importance of integrating previous knowledge in the current analysis, for which novel approaches offer a variety of tools. We note, however, that the drawbacks and benefits of these approaches have yet to be carefully examined in association with behavioral data. Therefore, we encourage a philosophical change in the interpretation of statistical outcomes, whereas we still retain a pluralistic perspective for making objective statistical choices given the uncertainties around different approaches in behavioral ecology. We provide recommendations on how these concepts could be made apparent in the presentation of statistical outputs in scientific papers.

A further development in social marketing application of the MOA framework and behavioral implications

This social marketing study discusses the application of Rothschild’s MOA framework (Motivation, Opportunity, and Ability) in a land-use management context. The authors hypothesize that landholders with higher levels of MOA are positively associated with behavior that would result in the effective control of a vertebrate pest (the European rabbit). A random sample of 566 land managers in southeastern Australia was obtained. The development of scales associated with this study were the result of intensive qualitative research, including focus groups, in-depth interviews, and a thorough review of secondary resources. The scales were developed through a factor analytic process and were piloted and pre-tested before being used.

From the study it is ascertained that about one-third of land managers fall into the highest level of effective behavior, and for the remainder, social marketing interventions, using marketing, education, and the law, could be applied to changebehavior. The study provides evidence that Rothschild’s theoretical MOA framework can be applied to a social market and thus provides guidance on the types of interventions that may be effective in altering behavior. The MOA framework also provides a mechanism for segmentation that can be used to describe various markets and gives direction to the interventions that may be effective in altering behavior.

Neuropsychological changes following cognitive-behavioral treatment of obsessive-compulsive disorder (OCD)

Previous research has suggested that individuals with OCD show compromised performance on tests assessing visuospatial and executive processes. This study aimed to further examine such findings by investigating the relationship between OCD symptom improvement following cognitive-behavioral therapy and changes in neuropsychological performance in individuals with OCD (n = 26), compared to test-retest control participants (n = 10). Successful treatment of OCD led to improvements relative to the control group on neuropsychological tasks measuring spatial working memory. Neuroscientific models of OCD consider such findings to be consistent with possible cortical dysfunction in OCD. However, a significant limitation of the study is in its inability to discount alternative explanations for this finding, such as the influence of changes in beliefs. Implications are discussed.

A low power micro deep brain stimulation device for murine preclinical research

Deep brain stimulation has emerged as an effective medical procedure that has therapeutic efficacy in a number of neuropsychiatric disorders. Preclinical research involving laboratory animals is being conducted to study the principles, mechanisms, and therapeutic effects of deep brain stimulation. A bottleneck is, however, the lack of deep brain stimulation devices that enable long term brain stimulation in freely moving laboratory animals. Most of the existing devices employ complex circuitry, and are thus bulky. These devices are usually connected to the electrode that is implanted into the animal brain using long fixed wires. In long term behavioral trials, however, laboratory animals often need to continuously receive brain stimulation for days without interruption, which is difficult with existing technology. This paper presents a low power and lightweight portable microdeep brain stimulation device for laboratory animals. Three different configurations of the device are presented as follows: 1) single piece head mountable; 2) single piece back mountable; and 3) two piece back mountable. The device can be easily carried by the animal during the course of a clinical trial, and that it can produce non-stop stimulation current pulses of desired characteristics for over 12 days on a single battery. It employs passive charge balancing to minimize undesirable effects on the target tissue. The results of bench, in-vitro, and in-vivo tests to evaluate the performance of the device are presented.
