The Ranking of Self-Actualization Values: The Effects of Class, Stratification, and Occupational Experiences*

This paper examines the influence of social class, occupational experiences, and a variety of stratification factors on the ranking of a set of important life goals. Based on a national sample of Canadians from 1977, the findings indicate modest class differences in the evaluation of four "self-actualization" values. Specifically, middle class respondents rank "self-development,""achievement," and "activism" as more important than do working class respondents. There are no significant differences on the fourth concern, "independence." Multi-variate analysis reveals that the class differences in values are wholly attributable to differences in occupational experiences and educational training in the two class groupings. These findings are consistent with Kohn's thesis of "class and conformity." Additional controls on a set of stratification factors-sex, income, age, and language group (English/French)-suggest almost no differences between dominant and subordinate groups in the ranking of the four values. Only age has a significant influence, with the young rating self-actualization as more important than the old. The implications of these results for the study of dominant values and ideology and for the relationship between social inequality and values are briefly considered.     

The Relationship Between Culture,Geographic Region,and Gender on Body Image: A Comparison of College Students in the Southeast and Pacific Northwest Regions of the United States

Body image is a significant predictor of important psychological and physical outcomes. The current study sought to expand on previous research on cross-cultural differences in body image across countries by exploring differences in body image based on geographic region within the United States. A sample of 1,365 participants was recruited from universities in the Southeast and Pacific Northwest regions of the United States. Participants completed a survey that assessed their gender, geographic region, and body image. Women reported poorer body image than men, and young adults from the Southeast reported poorer body image than young adults from the Pacific Northwest. There were significant interaction effects for gender and geographic region with women from the Southeast reporting the poorest body image of any group. The authors suggest that sociocultural differences in standard of beauty in the Southeast as well as differences in dress related to climate may contribute to the findings.     

Pulling ads,making apologies: Lowe's use of Facebook to communicate with stakeholders

This study examines the use of Facebook by Lowe's to reach its stakeholders after the controversial decision to pull its advertising from TLC's All-American Muslim. Through an online survey, the study gauges people's thoughts about the use of Facebook to apologize. Results showed significant differences based on age, race/ethnicity, and political affiliation regarding the use of Facebook and significant differences based on education, time spent on Facebook, political affiliation and race/ethnicity regarding the wording of Lowe's apology.     

The Effect of Gender on Sex-Role Attitudes

Abstract

An examination of the contradiction between college student studies and national public opinion polls.

The evidence concerning the existence and magnitude of gender differences in sex-role attitudes is contradictory. A large number of studies, based primarily on college samples, have reported significant gender differences in the sex-role attitudes of young adults; males have been found to be more traditional than females. However, studies based on national samples including all age and educational groups have not found consistent gender differences. In order to investigate this contradiction, NORC General Social Survey was aggregated from the years 1974 through 1978 to create a data set that included a large number of young adults who were currently attending or who had recently attended college. Both age and education were found to be significant predictors of sex-role attitudes, but for most of the items examined gender differences were not found to be larger for young adults than for older adults. For both age groups larger gender differences were found in items pertaining to caring for children than for items pertaining to women's roles in the public sphere.     

Gender differences in the use of high-variance strategies in tournament competition

We report on a series of experiments in which participants first completed a simple game of chance and then competed in a tournament based on a multiple cue probability learning task. The results show that men made riskier choices in the simple game of chance, but women adopted the high-variance strategy more frequently in the tournament. However, after controlling for differences in forecasting skill, we find no significant differences in the rates at which men and women adopted a high-variance strategy. Although altering the difficulty of the forecasting task produces differences in the rate at which participants selected the high-variance strategy, it did not produce a significant difference in the rate at which men and women selected the strategy. Thus, this paper suggests that although women are more risk-averse than men, women are no less likely to adopt a high-variance strategy in a tournament competition.     

The effect of unions on labor markets and economic growth: An analysis of state data

Despite voluminous research on unions, there still is no consensus on how unions affect a state's economy. Using a panel of 48 U.S. states for the 1978–1994 period, we estimate a series of simultaneous equations to analyze how unions affect various economic barometers. This provides measures for the partial correlations between unions and performance. The model is then re-estimated using regional dummies to capture fixed effects and to highlight regional differences in the slope of the Phillips curve. We find that unions adversely affect unemployment rates and the growth rates of gross state product (GSP), productivity, and population, while increasing the rate of wage inflation. The impact on the employment growth rate is negative but not significant. A test for fixed effects reveals regional differences in GSP growth. Regional differences in popu-lation growth are not significant. Also, the slope of the Phillips curve is significantly dif-ferent across regions.     

Career Maturity Levels of Male Intercollegiate Varsity Athletes

This study examined the readiness of male intercollegiate varsity athletes to make career-related decisions. The research questions compared students participating in revenue- and nonrevenue-producing sports as well as Caucasian and minority (Black, Asian American, Hispanic American, Native American, and other) student-athletes on eight dimensions of career maturity measured by the Career Development Inventory (Super, Thompson, Lindeman, Jordaan, & Myers, 1981). No significant differences were found in the overall career maturity of the student-athletes based either on the type of sport played or on their race. Also, the interaction of type of sport and race was not significant in determining differences in student-athletes' career maturity levels. Implications for career counseling programs for student-athletes and future research are discussed.     

College student perceptions of crime and casino gambling: a preliminary investigation

To gain insight into how attitudes toward casino gambling vary by an area's experience with gambling, a survey was given to 415 university students at the University of Nevada, Reno, and 420 students at the University of Memphis. Casino gambling has been legal in Reno since 1931, but was introduced in the Memphis area in 1992. Given the differences in duration and degree of integration of casinos in each area, significant differences were expected by area in respondents' perceptions of casinos and casino gambling. While some significant differences were found, the most prominent finding is the degree of similarity of attitudes of students in each university and the high percentage in each sample that associated casino gambling with types of crime. Where significant differences did exist, the findings are interpreted as supporting either an exposure hypothesis or a cultural conservatism hypothesis.     

Civic Engagement Among Older Adults in a Rural Community

Abstract

This is a report of the second and final stage of a research project evaluating courses for community activists in Israel. We compared 286 graduates of Schools for Community Activists, of whom 198 were still active in their communities and 98 were not, with 138 activists and 131 non-active residents of the same neighbourhoods who had never participated in courses for activists. We noted no significant socio-economic or demographic differences between the graduates and the non-graduates. However, on a range of variables, we found consistent and generally significant differences between the graduate and non-graduate activists: the former reported higher levels of activism, knowledge and skills, higher community involvement and deeper community roots, and assessed more highly the prestige of community involvement. Few differences were noted on their assessment of the benefits and losses of community activity. Since the graduates and non-graduates come from similar backgrounds, we conclude that the courses made a significant contribution to the development and socialization of those activists who participated in them.     

Gender and Agricultural Science: Evidence From Two Surveys of Land‐Grant Scientists*

Abstract We test two sets of hypotheses concerning the association between gender and various structural and attitudinal variables, using data collected in two surveys (1979 and 1995–1996) from random samples of land‐grant agricultural scientists. The first set of hypotheses centers on the expectation that the resources and rewards of agricultural science are distributed unequally by gender. We find significant gender differences in scientists' postdoctoral work experience, academic rank, employment of graduate students, rate of book publication, and links with private industry. Our second set of hypotheses, drawing on the literatures of feminist epistemology and situated knowledge, focuses on the relationship between scientists' gender and perceptions of the goals of agricultural research. Our findings indicate that gender is unimportant in explaining differences in scientists' commitment to agricultural sustainability, environmental issues, and family farm preservation as important goals of land‐grant research. Yet we find significant gender differences in attitudes toward biotechnology and the growing links between land‐grant universities and private industry.     

Female and male undergraduates' attributions for sexual offending against children

This study examined gender differences in undergraduates' attributions for child sex offending. One hundred and sixty-four undergraduates were asked to give the reasons why they think men sexually offend against children and to rate them using Benson's Attributional Scale across four dimensions: stability, locus, controllability and globality. A Grounded Theory methodology was applied to these reasons and a set of nine categories derived from the data. The results showed that undergraduates' reasons for child sexual abuse strongly parallel contemporary scientific theories of abuse, and that there were significant gender differences in the frequency with which participants cited various types of reasons given for sexual abuse. Females endorsed significantly more victim reasons than males, and also more power and control reasons than did males. In contrast, males endorsed significantly more sexual reasons for offending than did females. Furthermore, significant gender differences were found between the ways in which participants construed the reasons for sexual abuse, with females seeing the phenomenon as significantly more stable and internal than males. No significant gender differences were found on the dimensions of controllability and globality.     

Testing the Clinical Implications of Planned Missing Data Designs

Assessment is a core element of evidence‐based practice, but thorough formal assessment can place a significant burden on clients. We evaluated the clinical viability of using planned missing data designs to reduce client burden. Data come from an archival dataset with 1342 participants. Although significant differences were found in scores with planned missing data versus real scores, the effect sizes for the differences were generally small. Scores with missing data had sensitivity and specificity scores generally above .90 when predicting real scores over clinical cutoffs and improvement in real scores. These findings offer useful information to agencies and researchers looking for ways to collect more data without losing its immediate clinical utility.     

The effect of alternative staff time data collection methods on drug treatment service cost estimates

Although a limited number of service cost estimates exist, no study has evaluated how differences in the method used to collect the staff time allocation across treatment services contribute to differences in service cost estimates. Three alternative data collection methods for estimating service-level costs in methadone treatment programs were evaluated: key informants, staff surveys, and staff diaries. We analyzed data from 25 methadone clinics across the United States. Results indicate that for the three primary services offered at methadone clinics—individual counseling, group counseling, and methadone dosing—no statistically significant differences exist in the mean estimates of costs per session across programs. Of the other five services analyzed, we found no statistically significant differences in two of the mean costs per session and a small but statistically significant difference in another service. We found large and statistically significant differences in mean costs for two services, initial patient assessment and initial medical services. Although there is no gold standard available to judge which method is the best to use, we concluded that the key informant method yields more reliable cost estimates compared with the staff methods and is less burdensome to both the treatment programs and to researchers. Our findings suggest that the key informant method is the preferred method for costing substance abuse treatment services.     

Family Structure Among Urban,Rural and Farm Populations: Classic Sociological Theory Revisited

Abstract As predicted by the classic sociological theories of Durkheim, Tonnies, and others, early sociological researchers found extensive differences between urban and rural residents in the United States. In recent decades, many of these differences have appeared to wane, or in some cases, totally disappear. Based on these classic theories, we maintain that many of the urban/rural differences found in the past were actually farm/nonfarm differences. Further, we argue that many of these differences continue to exist in rural America, but they have been suppressed by major demographic transitions. Utilizing Current Population Survey data on family structure, we found that there were few significant differences between urban and rural nonfarm residents, but both varied extensively from various segments of the farm population.     

Alcohol use and attitudes: a comparison of college athletes and nonathletes

The purpose of this study was to compare patterns of use and attitudes toward alcohol by college athletes and nonathletes. One hundred forty-six college students from colleges in the Jackson, Mississippi area were compared on athletic participation, sex, and race as these variables affected alcohol use and attitudes toward use. Data were collected by means of a questionnaire administered by the investigators. Chi squares and t-tests for differences between means were utilized to assess differences among subgroups on dependent variables. Analysis of data indicated that minimal differences existed in drinking behaviors of athletes and nonathletes. Athletic participation exerted a slight influence upon the drink of choice and patterns of drinking. Some significant racial and gender-related differences were found in drinking behaviors. The more negative attitudes of athletes toward alcohol consumption did not result in drinking behaviors distinct from nonathletes.     

PROFESSIONAL ACHIEVEMENTS AND GENDER DIFFERENCES AMONG ACADEMIC ECONOMISTS

This paper tests for gender differences in remuneration and professional achievement among academic economists using data on grants and grant applications to the National Science Foundation. A simultaneous equations model is used to examine the determinants of salary, rank, department affiliation and research output. In addition to confirming some long-standing folklore about the composition of faculty in research-oriented institutions, significant gender differences were found among older cohorts. Although the signs of the gender coefficients are consistent with a discrimination hypothesis for the sample of assistant professors, the results were not statistically significant.     

The effects of back belts and load on selected lifting kinematics during a simulated patient transfer

This study used two dimensional biomechanical analysis to examine the effects of back belts and lifting load on selected lifting kinematics during a simulated patient transfer. A human manikin placed in a sitting position was attached to a customized lifting apparatus which controlled the lifting load and direction of the manikin. Eighteen female participants, between the age of 21 and 27, completed six lifts (sit to stand transfers) of the manikin. Three lifts were completed at the 30 lb load condition (no belt, belt 1 and belt 2) and three lifts were completed at the 50 lb load condition (no belt, belt 1 and belt 2). A doubly two way ANOVA found a significant main effect for the belt condition, F(12,6)=10.06, P=0.002. There was no significant effect for load and no interaction existed between belt and load. The results revealed a significant decrease in trunk flexion when participants wore the wider (nine inch) belt during the 30~lb lifts when compared to the no belt trials. No significant differences were found in trunk flexion means with the narrower width (six inch) belt. No significant differences were found in trunk spinal flexion with either belt condition during the 50 lb lifts. There were no significant differences found in either of the belts in the means of lifting time, knee flexion, elbow flexion, forward displacement of the lifter's center of mass, and the lifter's maximum center of mass velocity. The results suggest that wider back belts may be more effective at reducing spinal flexion during patient lifting under moderate load conditions when compared to narrower back belts and to no-belted controls.     

Parenting with a Disability and Child Mental Health: A Propensity Score Analysis

Little research has examined the impact of having a parent with a disability on child mental health. This study used data from 7,116 families of children who participated in the 2006 National Health Interview Survey and propensity score matching (PSM) to investigate this question. Prior to PSM, differences in Child Mental Health Brief scores were significant with a moderate effect size. After PSM, differences in Child Mental Health Brief scores were still significant, but the effect size was small. Results indicate that much of the mental health risk for children of parents with disabilities is connected to related issues.
