Effects of concurrent training on interleukin-6, tumour necrosis factor-alpha and C-reactive protein in middle-aged men

The purpose of this study was to evaluate the effects of moderate- to high-intensity resistance and concurrent training on inflammatory biomarkers and functional capacity in sedentary middle-aged healthy men. Participants were selected on a random basis for resistance training (n = 12), concurrent training (n = 11) and a control group (n = 13). They performed three weekly sessions for 16 weeks (resistance training: 10 exercises with 3 × 8-10 repetition maximum; concurrent training: 6 exercises with 3 × 8-10 repetition maximum, followed by 30 minutes of walking or running at 55-85% [Vdot]O(2peak)). Maximal strength was tested in bench press and leg press. The peak oxygen uptake ([Vdot]O(2peak)) was measured by an incremental exercise test. Tumour necrosis factor-α, interleukin-6 and C-reactive protein were determined. The upper- and lower-body maximal strength increase for both resistance (+42.52%; +20.9%, respectively) and concurrent training (+28.35%; +21.5%, respectively) groups (P = 0.0001).[Vdot]O(2peak) increased in concurrent training when comparing pre- and post-training (P = 0.0001; +15.6%). No differences were found in tumour necrosis factor-α and interleukin-6 for both groups after the exercise. C-reactive protein increased in resistance training (P = 0.004). These findings demonstrated that 16 weeks of moderate- to high-intensity training could improve functional capacity, but did not decrease inflammatory biomarkers in middle-aged men.     

Filipino Arts Among Elders in Institutionalized Care Settings

The use of traditional art in recreational therapies is unexplored. This paper, thus, attempts to surface the unique power of traditional Filipino arts (TFA) as synergizing lens in capturing the individual and the collective experiences of a select group of Filipino elderly in an institutionalized care setting relative to their feelings of depression and self-esteem. Three Filipino elderly housed in an institutionalized care setting were chosen for this phenomenological study, a robotfoto and a series of semistructured interviews constitute the main data gathering tool. Field texts were subjected to phenomenological reduction via the repertory grid analysis. Emerged themes were subjected to a series of member checking procedures to ensure the trustworthiness of the reported data. Depression and self-esteem were interpreted via two emerged themes. The themes were Me, Myself, and Melancholy and Will Not Let My Worth Wither. Through recreational therapies in the form of traditional Filipino arts, participants found novel psychological crutches that overcame the challenges of depression and give them hope toward more positive views of themselves and life.     

Validity and reliability of rating perceived exertion in women with fibromyalgia: exertion-pain discrimination

The present study aimed (1) to assess the validity and reliability of the Borg category-ratio (CR-10) scale for monitoring exercise intensity in women with fibromyalgia (FM) and (2) to examine whether women with FM can discriminate between perceived exertion and exercise-induced pain. Thirty-three women with FM performed two incremental treadmill tests (1 week separated). Heart rate, oxygen uptake, minute ventilation and respiratory quotient were measured. The ratings of perceived exertion (RPE: CR-10 scale) and exercise-induced pain were obtained at each workload. The Spearman’s correlation of RPE with the physiological responses ranged from 0.69 to 0.79. The regression models explained ~50% of the variability of the studied physiological responses. We found “perfect acceptable” agreement in 69% of the observations. Weighted Kappa was 0.66 (95% confidence interval [CI]: 0.59–0.72). There were differences between RPE and pain at workloads 3 (1.50; 95%CI: 0.85–2.16), 4 (2.10; 95%CI: 1.23–2.96), 5 (3.40; 95%CI: 1.29–5.51) and 6 (3.97; 95%CI: 1.61–6.33). The main findings of the present study suggest that the Borg CR-10 scale is valid and moderately reliable for monitoring exercise intensity in women with FM, and these patients were able to discriminate between exertion and exercise-induced pain.     

On time-varying collaboration networks

The patterns of scientific collaboration have been frequently investigated in terms of complex networks without reference to time evolution. In the present work, we derive collaborative networks (from the arXiv repository) parameterized along time. By defining the concept of affine group, we identify several interesting trends in scientific collaboration, including the fact that the average size of the affine groups grows exponentially, while the number of authors increases as a power law. We were therefore able to identify, through extrapolation, the possible date when a single affine group is expected to emerge. Characteristic collaboration patterns were identified for each researcher, and their analysis revealed that larger affine groups tend to be less stable.     

Patterns of inequality in private funding of culture across the UK

By calculating an additively decomposable inequality measure following the lines of Shorrocks (1980; see Econometrica, 48(3)) we are able to evaluate regional disparities in private funding of cultural enterprises in the UK in a novel way. The country-wide index of inequality separates funding differences across regions from disparities within regions. Using data on private investment in UK cultural organisations, we consider three datasets: the first includes 139 organisations between 1993 and 2005; the second includes 573 organisations between 2002 and 2005; the third includes 898 organisations between 2005 and 2006. Differences among the 12 UK regions account for between a quarter and a third of overall funding inequalities. The largest contributor to funding inequality of cultural institutions in the UK is the degree of heterogeneity among cultural organisations within each region. We find that successful private fundraising is not significantly associated with the region where the organisation operates or with the particular cultural expression object of its activity. These are significant findings for cultural policymakers working on addressing issues of regional concentration of culture and diversifying sources of funding for the sector.     

Sermons,carrots or sticks? Explaining successful policy implementation in a low performance institution

This article explains how after 43 years of unsatisfactory outcomes, the Ministry of Education of Peru (MoE) suddenly ranked at the top of governmental performance tables. To do so, this study relies on implementation and major discussions of policy instrument theories to provide a comprehensive explanation of the reasons underlying the MoE’s improvements. Methodologically, this research employs the mixed research methods paradigm. It combines process-tracing and regression analysis. The analyses show that the MoE underwent three major events in its route to achieve policy success. First, the approval of a long-term policy plan (National Educative Plan to 2021); second, the contentious legitimisation of governmental policies against Peru’s teachers’ union and its eventual defeat; and, third, the recentralisation of historically dispersed control functions in the MoE. The results indicate that upon the occurrence of these reforms, MoE’s bureaucrats could gain teachers’ legitimacy and eventually achieve complementarity of policy tools. In fact, the multiple regression analysis suggests positive and significant interdependence between the set of tools employed by MoE officers: parents’ voluntary monetary contribution to schools (sermon), economic incentives to outperform schools (carrots) and trimestral oversight of schools’ performance (sticks). Results also show that MoE’s tools are positively associated with satisfactory student-learning outcomes.     

Validity of proximity sensor-based wear-time detection using the ActiGraph GT9X

Our study investigated the performance of proximity sensor-based wear-time detection using the GT9X under laboratory and free-living settings. Fifty-two volunteers (23.2 ± 3.8 y; 23.2 ± 3.7 kg/m²) participated in either a laboratory or free-living protocol. Lab participants wore and removed a wrist-worn GT9X on 3–5 occasions during a 3-hour directly observed activity protocol. The 2-day free-living protocol used an independent temperature sensor and self-report as the reference to determine if wrist and hip-worn GT9X accurately determined wear (i.e., sensitivity) and non-wear (i.e., specificity). Free-living estimates of wear/non-wear were also compared to Troiano 2007 and Choi 2012 wear/non-wear algorithms. In lab, sensitivity and specificity of the wrist-worn GT9X in detecting total minutes of wear-on and off was 93% and 49%, respectively. The GT9X detected wear-off more often than wear-on, but with a greater margin of error (4.8 ± 11.6 vs. 1.4 ± 1.4 min). In the free-living protocol, wrist and hip-worn GT9X’s yielded sensitivity and specificity of 72 and 90% and 84 and 92%, respectively. GT9X estimations had inferior sensitivity but superior specificity to Troiano 2007 and Choi 2012 algorithms. Due to inaccuracies, it may not be advisable to singularly use the proximity-sensor-based wear-time detection method to detect wear-time.     

Globalization,networks, and governance: Researching global ICT programs

Global ICT programs are defined as new and universal modes of organizing mediated by technology and enacted through a novel mix of policy instruments, international institutions, business interests, and techno/managerial concepts. Largely unexplored in the various fields studying innovation and digital technologies, such programs are of interest, not least because of their projected ability to promote innovation and help achieve new mechanisms of governance at local, national, and global scale. Based on relevant information systems research, this paper argues that we need a new theoretical understanding for the study of such programs and in order to explore their potential as a means of technology transfer and innovation in the developed and developing world.     

Interpretation of Score Reports by Diverse Subgroups of Parents

The degree to which diverse score users can understand and consume information presented in score reports dictates whether they are able to draw reasonable conclusions. The goal of this study was to understand how parents (a particularly understudied and heterogeneous stakeholder population) make interpretations from a hypothetical interactive score report. We used cognitive laboratories to evaluate how 35 parents from diverse educational and language proficiency backgrounds make sense of the information presented in hypothetical K-12 score reports. Results from this study demonstrate the diversity in the levels of comprehension across the assessed subgroups of parents, and highlight the need for and importance of additional support materials that can help parents understand and make sense of the information presented in score reports. Nevertheless, due to the hypothetical nature of the score report mockup evaluated and the small sample sizes, these results should be substantiated with additional research.
