On the same page: Improving the connection between public services units in academic libraries     

Elizabeth Marcus  Malti Turnbull 《College & Undergraduate Libraries》2018,25(2):101-109

Communication quality between public service units in academic libraries can make the difference between mediocre and exceptional service. If units do not communicate well, patrons may receive inaccurate information and experience short-term frustration, leading to long-term damage to the library's reputation. Poor communication creates adverse effects on employees through decreased productivity, negative work culture, and low morale. This article explores the importance of quality communication through a review of the literature and a case study at one academic library. The authors share practical communication improvement strategies for libraries of every size and fiscal ability.  相似文献   

Effectiveness of physical education to promote motor competence in primary school children     

Vítor P. Lopes  David F. Stodden  Luis P. Rodrigues 《Physical Education & Sport Pedagogy》2017,22(6):589-602

Background: Motor skill (MS) competence is an important contributing factor for healthy development.

Purpose: The goal was to test the effectiveness of primary school physical education (PE) on MS and physical fitness (PF) development.

Methods: Three classes (n?=?60, aged 9.0?±?0.9) were randomly assigned to three diverse conditions during a school year: two PE lessons/week (PE-2), three PE lessons/week (PE-3), and no PE lessons control group (CG). BMI, skinfolds, PF (9-min run/walk, sit-up, modified pull-ups), gymnastics, soccer, handball, basketball and track-and-field skills were evaluated. Effect sizes (d) were reported as magnitude of change.

Results: Skinfolds significantly increased only in CG (d?=?1.21). PF composite z-scores improved in PE-3 (d?=?0.61), but decreased in PE-2 (d?=?0.57), and had no changes in CG. Statistically significant improvement was verified in gymnastics and handball skills in both experimental groups (gymnastic: d?=?2.95 and d?=?2.61 for PE-3 and PE-2, respectively; handball: d?=?1.87 and d?=?0.57 for PE-3 and PE-2, respectively), and no changes were seen in CG. In soccer, there were improvements only in the PE-3 (d?=?0.55), and in basketball only in PE-2 (d?=?0.46). There were no changes in any group for track-and-field skills.

Conclusions: PE programs can effectively promote PF and MS development.  相似文献

Effects of psychosocial variables in the similarity and interdependence of physical activity levels among adolescent best friend dyads     

Vítor P. Lopes  Carl Gabbard  Luis P. Rodrigues 《Journal of sports sciences》2016,34(9):821-828

Given that physical activity (PA) tends to decrease with age during adolescence, addressing factors that affect change is important. This study examined the similarity and interdependence of PA as influenced by psychosocial factors among adolescent best friend dyads. A total of 660 adolescents, representing 330 best friend dyads, completed questionnaires with regard to PA, sitting time, perceived exercise benefits and barriers, physical self-perception and social support for PA. Dyads were also identified as reciprocal and non-reciprocal best friends; reciprocal means that both considered each other best friends and non-reciprocal were those in which only one considered the other a best friend. Data were analysed using a hierarchical linear model framework. Results indicated significant similarities between reciprocal best friend dyads for PA and sitting time, and for sitting time in non-reciprocal best friends (P values <.01). Psychosocial variables were associated with PA in reciprocal best friend dyads and with sitting time in reciprocal and non-reciprocal best friend dyads. Best friend gender, regular sports practice of the person, perceived exercise barriers of the best friend and best friend social support were the best predictors for PA.  相似文献   

Effects of 12 weeks of combined training without caloric restriction on inflammatory markers in overweight girls     

Wendell Arthur Lopes  Neiva Leite  Larissa Rosa da Silva  Diego Trevisan Brunelli  Arthur Fernandes Gáspari  Rosana Bento Radominski 《Journal of sports sciences》2016,34(20):1902-1912

The objective of the present study was to investigate the effects of combined training without caloric restriction on inflammatory markers in overweight girls. Thirty-three girls (13–17 years) were assigned into overweight training (n = 17) or overweight control (n = 16) groups. Additionally, a normal-weight group (n = 15) was used as control for the baseline values. The combined training programme consisted of six resistance exercises (three sets of 6–10 repetitions at 60–70% 1 RM) followed by 30 min of aerobic exercise (walking/running) at 50–80% VO_2peak, performed in the same 60 min session, 3 days/weeks, for 12 weeks. Body composition, dietary intake, aerobic fitness (VO_2peak), muscular strength (1 RM), glycaemia, insulinemia, lipid profile and inflammatory markers (C-reactive protein, interleukin-6, tumour necrosis factor-alpha, interleukin-10, leptin, resistin and adiponectin) were measured before and after intervention. There was a significant decrease in body fat (P < 0.01) and increase in fat-free mass (P < 0.01), VO_2peak (P < 0.01), 1 RM for leg press (P < 0.01) and bench press (P < 0.01) in the overweight training group. Concomitantly, this group presented significant decreases in serum concentrations of C-reactive protein (P < 0.05) and leptin (P < 0.05), as well as in insulin resistance (P < 0.05) after the experimental period. In conclusion, 12 weeks of combined training without caloric restriction reduced inflammatory markers associated with obesity in overweight girls.  相似文献

On the relationship between environmental management, environmental innovation and patenting: Evidence from German manufacturing firms   总被引：1，自引：0，他引：1  

Marcus Wagner   《Research Policy》2007,36(10):1587-1602

This paper analyses empirically the relationship between environmental innovations, environmental management and patenting. In particular it tests a number of propositions on how environmental management systems and the interaction with environmentally more or less concerned stakeholders are associated with the probability of firms to pursue innovation in general (measured as patenting behaviour) and specifically environmental innovation (measured based on firm self-assessment and through patent data). In applying a negative binomial as well as binary discrete choice models the relationship is studied using data on German manufacturing firms. As a novel and important insight, the study finds that environmental innovation can be meaningfully identified using patent data and that environmental innovation defined this way is less ubiquitous than self-reported environmental innovation. It also reveals that the implementation level of environmental management systems has a positive effect exclusively on environmental process innovation, whereas it is negatively associated with the level of a firms’ general patenting activities. For environmental product innovation and patented environmental innovations a positive relationship with environmentally concerned and a negative link with environmentally neutral stakeholders is found.  相似文献   

Application of real options analysis for pharmaceutical R&D project valuation—Empirical results from a survey     

Marcus Hartmann  Ali Hassan 《Research Policy》2006,35(3):343-354

Real options analysis was often recommended as an emerging valuation technique for high-risk investment projects. Former inter-sectoral surveys have drawn an ambivalent picture of real options usage in general. In addition, there is a lack of sector-specific investigations. In the following article the results of an in-depth analysis of collected empirical data regarding the application of this new tool in the pharmaceutical sector is presented by capturing the internal view from the pharmaceutical companies themselves and the external view from the health care departments of financial service firms. R&D stage specific modi of application, reasons for reluctance in the employment of real options and their assumed future prospects are elucidated.  相似文献
