“易筋经”改善老年人体能衰退初探

老年人的体能衰退伴随着机体的老年性退化,研究一套有利于改善老年性机体衰退的锻炼方法,更好地改善和提高老年人的体能,可达到延缓衰老的目的。“易筋经”不仅具有充分调动和增强“元神”、“元气”的生理作用,提高大脑支配机体的能力和人体生命活动的原动力（内状）,同时还能发展肌力、提高筋、骨、皮的生理机能（外强）,从而使“内状”和“外强”高度平衡地发展,达到机体本质性改善的效果。作者根据“易筋经”的功理功法,与老年人的生理特点相结合,对18位平均年龄65岁的老年人进行了测试,通过5个多月的练功在改善和提高体能标准和6项身体素质方面,都取得了满意效果。另外,易筋功还有好学易练,不受场地器械限制,不易出偏,便于推广等等的优点。

University-incubator firm knowledge flows: assessing their impact on incubator firm performance

Technology incubators are university-based technology initiatives that should facilitate knowledge flows from the university to the incubator firms. We thus investigate the research question of how knowledge actually flows from universities to incubator firms. Moreover, we assess the effect of these knowledge flows on incubator firm-level differential performance. Based on the resource-based view of the firm and the absorptive capacity construct, we advance the overarching hypothesis that knowledge flows should enhance incubator firm performance. Drawing on longitudinal and fine-grained firm-level data of 79 technology ventures incubated between 1998 and 2003 at the Advanced Technology Development Center, a technology incubator sponsored by the Georgia Institute of Technology, we find some support for knowledge flows from universities to incubator firms. Our evidence suggests that incubator firms’ absorptive capacity is an important factor when transforming university knowledge into firm-level competitive advantage.

Association between 11beta-hydroxysteroid dehydrogenase type 1 gene polymorphisms and metabolic syndrome in Bosnian population

Introduction:

The enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) catalyzes the conversion of the hormonally inactive cortisone to active cortisol, thus facilitating glucocorticoid receptor activation in target tissues. Increased expression of 11β-HSD1 in adipose tissue has been associated with obesity and insulin resistance. In this study, we investigated the association of two 11β-HSD1 gene (HSD11B1) polymorphisms with the metabolic syndrome (MetS) and its characteristics in the Bosnian population.

Materials and methods:

The study included 86 participants: 43 patients diagnosed with MetS and 43 healthy controls. Subjects were genotyped for two HSD11B1 gene polymorphisms: rs846910: G>A and rs45487298: insA, by the high resolution melting curve analysis. Genotype distribution and an influence of genotypes on clinical and biochemical parameters were assessed.

Results:

There was no significant difference in the mutated allele frequencies for the two HSD11B1 gene polymorphisms between MetS patients and controls. In MetS patients, no significant associations between disease-associated traits and rs45487298: insA were found. Regarding rs846910: G>A variant, heterozygous patients (G/A) had significantly lower systolic (P = 0.017) and diastolic blood pressure (P = 0.015), lower HOMA-IR index (P = 0.011) and higher LDL-cholesterol levels (P = 0.049), compared to the wild-type homozygotes. In the control group, rs45487298: insA polymorphism was associated with lower fasting plasma insulin levels (P = 0.041), lower homeostasis model assessment insulin resistance (HOMA-IR) index (P = 0.041) and lower diastolic blood pressure (P = 0.048). Significant differences between rs846910: G>A genotypes in controls were not detected. Haplotype analysis confirmed the association of rs45487298: insA with markers of insulin resistance in the control subjects.

Conclusions:

Our results indicate that a common rs45487298: insA polymorphism in HSD11B1 gene may have a protective effect against insulin resistance.     

What influences transfer of training in an African agricultural research network?

Purpose: This study determined the extent to which transfer of training among trainees from national partners of an international bean research network in Africa was perceived to have taken place; including determining the factors that predicted transfer of training back to the job. Methodology/approach: Online data collection using the Learning Transfer Systems Inventory (LTSI) from 139 respondents was made and analyzed using bivariate correlations and hierarchical multiple regression. Findings: An average of 75% of the training skills were perceived as transferred. ‘Personal capacity’ significantly predicted transfer, while ‘motivation to transfer’, ‘transfer design’, ‘supervisor’, and ‘peer support’ positively correlated with training transfer. Theoretical implications: The LTSI factors remain relevant explanations for training transfer with in African agricultural research and development organizations. Certain work environments are likely to have new factors such as ‘Supervisor and peer’ support which operated as one explanatory factor for training transfer, revealed the closeness of supervisors and peers in agricultural research and development settings. Practical implications: The international agricultural research network needs to consider the trainees’ ability to transfer new training given workload-related hindrances. Originality/value: The applicability of the LTSI for international agencies that conduct training for agricultural research and development in Africa has been tested. Such institutions need policies that enhance trainee capacity to transfer training to the work place.
