Intra- and inter-subject variation in lower limb coordination during countermovement jumps in children and adults

The purpose of the present study was to investigate the coordination pattern and coordination variability (intra-subject and inter-subject) in children and adults during vertical countermovement jumps. Ten children (mean age: 11.5 ± 1.8 years) and ten adults (mean age: 26.1 ± 4.9 years) participated in the experiment. Lower body 3D-kinematics and kinetics from both legs were obtained during 9 vertical jumps of each subject. Coordination pattern and coordination variability of intra-limb and inter-limb coupling were established by modified vector coding and continuous relative phase. The adult group jumped higher and with less performance variability compared to the children. Group differences were mainly observed in the right–left foot coupling. The intra-subject coordination variability was higher in coupling of proximal segments in children compared to adults. No group differences were observed in inter-subject variability. Based on these results, it was concluded that the same movement solutions were available to both age groups, but the children were less able to consistently utilize the individually chosen coordination pattern. Thus, this ability appears to be developed through normal ontogenesis.     

Four types of fare evasion: A qualitative study from Melbourne,Australia

Fare evasion on public transport can reduce revenue by millions of dollars, undermining the financial viability of transit. However little research examines how public transport users think about fare evasion or attempts to understand why people fare evade. This paper presents the results of a program of qualitative research conducted in Melbourne, Australia to understand the attitudes toward and motivations behind fare evasion. A total of 67 people participated in face-to-face or online focus groups.Results established a spectrum of perceived circumstances where someone might travel without a valid ticket. ‘Fare evasion’ was considered to be at only one end of that spectrum. The degree of intent to evade was a critical factor explaining the severity of fare evasion from user perspectives. People’s attitudes toward fare evasion differed significantly; four key attitude segments were uncovered based on the attitudes and behaviours that group members tended to share. These included 1. ‘Fare evasion is wrong – the accidental evader’ who held strong views against fare evasion, 2. The ‘it’s not my fault’ evader who meant to pay but sometimes find themselves fare evading due to barriers to payment, 3. The ‘calculated risk-taker’ evader who deliberately fare evade if they think the reward outweighs risk and 4. ‘Career evaders’ who always fare evade. Attitudes, feelings and motivations for these segments are described and implications for revenue protection policy are discussed.     

The Virtual Universe, the Open Large Group, and Maturational Processes in the Future

The technology of the future will bring a new, world-wide, interactive but virtual social experience to our parlors and desktops in place of face-to-face relationships. Governments will stand or fall on the basis of electronically mediated communication with masses of people. Adventures in this new open large group context in the outer world, and the maturation of our inner selves may mirror as well as contribute to each other. Small group experience and group therapy, in particular, may play a vital role.     

Ethnoracial comparisons in anxiety and depression outcomes among Native Hawaiian and Pacific Islander college students

We explored differences in distress scores at intake as well as the change in anxiety and depression scores over the course of 12 therapy sessions for Native Hawaiian and Pacific Islander (NHPI) college students. Data were collected from the Center for Collegiate Mental Health (N = 256,242). Results support the notion that NHPI college students experience anxiety and depression in therapy differently from other ethnic groups with moderate-to-large magnitudes of effect.     

Reducing ethnic prejudice by public campaigns: an evaluation of a present and a new campaign

Most Western governments consider it their responsibility to counteract ethnic prejudice and discrimination, and they sometimes instigate persuasive communication programmes to achieve this aim. Generally, these campaigns do not have the desired effects possibly because designers of such persuasive communication programs have ignored relevant social‐psychological theoretical insights concerning prejudice. In this experiment, a present campaign (launched by the British Commission for Racial Equality) and a new campaign (developed by us) were evaluated. We hypothesized that our campaign would lead to lower levels of prejudice than the present campaign, because when designing our campaign relevant theoretical insights were more sufficiently taken into account. White participants (n=190) were randomly assigned to one of two experimental conditions or to the control condition. Those in the experimental conditions were exposed to either the present campaign or the new campaign before completing a questionnaire about ethnic minorities. Participants in the control condition were not exposed to a campaign. Results supported the hypothesis and some implications for designing campaigns are discussed.

Response: How Do We Know What We Know About the Amish and Other Minorities?

The appraisal by Cory Anderson, Joseph Donnermeyer, Jeffrey Longhofer, and Steven Reschly (hereafter, appraisers) highlights a methodological divide that is important to the study of the Amish and other ethnic or religious minorities. In my reply, I discuss how my work is rooted in a cultural analytic paradigm that differs from the appraisers’ methodological orientation. My reply includes a deconstruction of the appraisal and a discussion of its “shortcomings.” I conclude by showing how the discourse surrounding this appraisal raises important epistemological questions of how we understand human societies.     

Specific job search self‐efficacy beliefs and behaviors of unemployed ethnic minority women

This two‐wave field study draws from social cognitive theory to investigate the specific job search self‐efficacy beliefs and behaviors of unemployed ethnic minority women in the Netherlands. We go beyond prior job search research that predominantly used white samples and conceptualized job search self‐efficacy and behavior as global, unidimensional constructs. We found that networking self‐efficacy and Internet self‐efficacy were the main predictors of ethnic minority women’s job search behaviors. Moreover, the more time they spent on contacting employment agencies and looking at job ads the more job offers they received. Finally, time spent on job ads was more positively related to job offers when job ad self‐efficacy was high and time spent on networking only predicted job offers when networking self‐efficacy was high.     

The Ethnic Adornment Survey (EAS): Measuring Individuals’ Use of Clothing to Express Ethnic Identity

The present paper introduces the Ethnic Adornment Survey as a measure of the relative frequency with which individuals use clothing to express their ethnic identity. Results of exploratory factor analyses in a pilot study (n = 174) and confirmatory factor analyses in a main study (n = 217) revealed that the Ethnic Adornment Survey measures two positively correlated, yet distinct, ethnic adornment factors (i.e., socially desirable and undesirable aspects). Moreover, results of regression analyses indicated that (1) self-esteem was positively predicted by socially desirable aspects of ethnic adornment (p’s < .05 in both studies); whereas (2) self-esteem was negatively predicted by socially undesirable aspects of ethnic adornment (p’s < .05 in the pilot study and < .10 in the main study). Implications for research on ethnic identity are discussed.
