This study aimed to analyse the association of different components of physical fitness, body composition, cardiometabolic markers and the Mediterranean diet with bone mineral density (BMD) in perimenopausal women, and to test which of these components are independently associated with BMD. The sample comprised 197 perimenopausal women (52.6 ± 4.5 years). Physical fitness was assessed with the “Senior Fitness Test” battery and the handgrip strength and Bruce tests. Fat and lean mass and BMD were measured using dual-energy X-ray absorptiometry. We analysed the markers of metabolic syndrome, C-reactive protein, and components of the Mediterranean diet. Handgrip muscle strength (β = 0.212, P = 0.005), body weight (β = 0.244, P = 0.001), BMI (β = 0.180, P = 0.011) and lean mass (β = 0.379, P < 0.001) were positively associated with BMD. No associations were observed between cardiometabolic markers or the Mediterranean diet with BMD (all P > 0.05). When all relevant indicators of BMD were simultaneously considered, lean mass was the only 1 showing an independent association with BMD (β = 0.392, P < 0.001), explaining 14% of the BMD variability. In conclusion, muscle strength might be a marker of BMD in perimenopausal women. However, lean mass was the only factor independently associated with BMD. Future research to determine whether increasing lean mass through specific exercise-based interventions contributes to increasing BMD is warranted.  相似文献

The School for Science and Math at Vanderbilt: An Innovative Research-Based Program for High School Students

The School for Science and Math at Vanderbilt (SSMV) is an innovative partnership program between a Research I private university and a large urban public school system. The SSMV was started in 2007 and currently has 101 students enrolled in the program, with a total of 60 students who have completed the 4-yr sequential program. Students attend the SSMV for one full day per week during the school year and 3–6 wk in the summers following their ninth- to 11th-grade years, with each grade of 26 students coming to the Vanderbilt campus on a separate day. The research-based curriculum focuses on guiding students through the process of learning to develop questions and hypotheses, designing projects and performing analyses, and communicating results of these projects. The SSMV program has elevated the learning outcomes of students as evidenced by increased achievement scores relative to a comparison group of students; has provided a rigorous research-based science, technology, engineering, and mathematics elective curriculum that culminates in a Summer research internship; has produced 27 Intel and Siemens semifinalists and regional finalists over the past 4 yr; and has supported the development of writing and communication skills resulting in regional and national oral presentations and publications in scientific journals.  相似文献

Testing Role Models’ Differential Effect on Use of Aggressive Compliance Gaining Strategies     

Kristen Eis Cvancara  Lucas Youngvorst  Virginia Otto  Christopher Brown 《Communication quarterly》2016,64(1):36-54

Using a repeated measures design, this empirical study confirmed that a differential relationship exists between significant role models’ use of aggressive compliance gaining strategies (ACGS) and an individual’s use of the same in romantic and non-romantic interactions. As expected, peer use was found to have the strongest relationship to individual use of ACGS with romantic partners. Unexpected was the similarity in strength of parent and peer use to individual use of ACGS with non-romantic partners. Relevance and opportunity are mechanisms used to explain role model impact as an antecedent variable of ACGS use. Future studies to advance theory regarding aggressive communication are discussed.  相似文献   

Psychosocial Attributes and Life Experiences of Disadvantaged Minority Mothers: Age and Ethnic Variations   总被引：1，自引：0，他引：1

This study examined age and ethnic differences in psychosocial factors among hispanic (n = 210) and black (n = 73) low-income mothers within 2 days after delivery. The sample included 45 black and 99 hispanic adolescents (less than 19 years) and 139 adult controls (greater than or equal to 20 years) giving birth on the service ward at a large metropolitan hospital, excluding mothers and infants with high parity or adverse perinatal conditions. Multivariate and univariate analyses, with parity covaried, revealed age effects including earlier menarche, more school grade retention, and more perceived social support among teens. No age differences were found in child-rearing attitudes, self-esteem, or depressive symptoms. Black mothers reported more social support, higher self-esteem, and less strict child-rearing attitudes than hispanics. Analyses within the hispanic sample revealed Dominican/Puerto Rican group differences in measures of family structure and child-rearing attitudes, but only small differences in social support. Ethnocultural differences between blacks and hispanics and between the two hispanic subgroups are considered in relation to the process of acculturation.  相似文献   

An analysis of the contribution of participative decision making and communication with supervisor as predictors of job satisfaction     

Virginia Eman Wheeless  Lawrence R. Wheeless  Richard D. Howard 《Research in higher education》1983,18(2):145-160

This study examined the relationships of (1) perceived participation in decision making, (2) communication with supervisor, (3) employee characteristics, and (4) employee job satisfaction. Classified employees in three administrative units at a comprehensive eastern university in the United States served as subjects. Results of canonical correlation andt-ratio tests demonstrated that job satisfaction was most strongly and positively related to communication satisfaction with supervisor and supervisor's receptivity to information. Implications are discussed in reference to personnel decisions and training, employee productivity, and the possible adverse effects of initiating a participative program of decision making for nonprofessional university employees.Presented at the 22nd Annual Forum of the Association for Institutional Research, Denver, May 1982.  相似文献

Discerning student thinking: a practical theoretical framework for recognising or informally assessing different ways of thinking     

Clinton Golding 《Teaching in Higher Education》2019,24(4):478-492

We expect our students to learn different ways of thinking, such as historical empathy or scientific reasoning, reflection, critical analysis, or clinical reasoning. But how do we discern if they have learned these ways of thinking when thinking is often abstract, tacit and seemingly invisible? In this conceptual and theoretical article, I argue that we can discern any kind of thinking, however we define it, if we focus on the observable actions or thinking behaviours associated with that thinking. Based on this argument, I then offer a theoretical framework for teachers so they might recognise and informally assess the particular kind of student thinking they want to cultivate. This framework synthesises several important theories about how we learn to think, and distinguishes six general features a teacher might look for to be more discerning about any kind of thinking: visibility, complexity, frequency, flexibility, independence, and application of the thinking behaviours.  相似文献
