This study examined the kinetic and temporal differences between countermovement jumps (CMJs) and eccentrically loaded CMJs. A survey of 109 coaches and athlete showed that 87% of respondents regularly used jumps with added mass within training. Sixteen male and thirteen female track and field athletes from sprinting, hurdling and jumping events performed 5 bodyweight CMJs 5 jumps wearing a weighted jacket and 5 eccentrically loaded dumbbell (LDB) jumps trials in a randomised order. Peak force (PF), peak power (PP), flight time (FT), concentric time (CON-T), eccentric time (ECT), total time (TIME) and eccentric/concentric ratio (E/C-Ratio) were obtained from force plate data. Statistically significant differences (p < 0.05) with moderate to large magnitude effect sizes were found between men and women in FT, PP and PF but not in any of the temporal variables. The results indicated that the WJ decreased FT in men (↓9%) and women (↓10%) but LDB jumps had similar FT to CMJ. Overall, the results showed that LDB increased the E/C Ratio (↑50% and ↑42%) and decreased CON-T (↓37% and ↓25%) compared with WJ and CMJ respectively. LDB jumping is not recommended as a training modality as it tends to disrupt the relative timing of the jump action.  相似文献

Noting that interactivity is often defined but seldom theorized in the literature, this article provides some pointers for developing theories about effects of interactivity, particularly as it applies to Web-based mass communication. It first makes the case that interactivity is an attribute of the technology and not that of the user. It exposes the tautology of studying the effects of perceived interactivity and calls for the consideration of ontological aspects that constitute interactivity while specifying its social and psychological effects. Theoretical explorations may be categorized in terms of three classes of outcome measures—behavioral, attitudinal, and cognitive—as we investigate the role played by interactivity in initiating action, changing attitudes, and altering the nature of information processing. These would result in theories about technology rather than psychology in that they help us specify direct and combination effects of interactivity, modality, navigability, and other technological attributes of the Web medium.  相似文献

Ocimum sanctum Linn. (also known as Tulsi) is a sacred Indian plant, the beneficial role of which, in obesity and diabetes is described traditionally. This is a randomized, parallel group, open label pilot study to investigate the effect of O. sanctum on metabolic and biochemical parameters in thirty overweight/obese subjects, divided into two groups A and B. Group A (n = 16) received one 250 mg capsule of Tulsi (O. sanctum) extract twice daily in empty stomach for 8 weeks and group B (n = 14) received no intervention. Statistically significant improvements in the values of serum triglycerides (p = 0.019); low density lipoprotein (p = 0.001); high density lipoprotein (p = 0.001); very low density lipoprotein (p = 0.019); Body Mass Index, BMI (p = 0.005); plasma insulin (p = 0.021) and insulin resistance (p = 0.049) were observed after 8 weeks in the O. sanctum intervention group. The improvement in HDL-C in the intervention group when compared to the control group was also statistically significant (p = 0.037). There was no significant alteration of the liver enzymes SGOT and SGPT in both the intervention (p = 0.141; p = 0.074) and control arms (p = 0.102; p = 0.055) respectively. These observations clearly indicate the beneficial effects of O. sanctum on various biochemical parameters in young overweight/obese subjects.  相似文献

‘Professional Ethics’ has been offered as a compulsory course to undergraduate engineering students in a premier engineering institution of India. It was noticed that students’ perceptions and attitudes were frivolous and ornamental towards this course. Course instructors and institution authorities were motivated to find out the factors contributing to this awkwardness. For this purpose, a questionnaire was prepared and administrated to 336 students registered for the July–November 2014 semester. The study found two factors contributing to students’ indifference towards the Professional Ethics course. First, most of the students did not have self-interest to join the engineering programme, and while pursuing their study, they decided to switch to a different field upon completion of their engineering study. Second, students who desired to be engineers in their future believed that engineering code of ethics is not really referred to in most of the engineering jobs, and therefore Professional Ethics course is only meant for classroom discussions.  相似文献

Can the comments of a few viewers on social media affect viewers’ perceptions of audience sentiment or their own program enjoyment? If so, do the effects of comments vary based on their valence or placement during programming? We conducted a 2 (positive vs. negative tweets) x 2 (beginning vs. end of program) factorial experiment with an additional control condition (N = 196) to answer these questions. Negative comments undermined perceived bandwagon support for the program and reduced enjoyment, regardless of contextual or trait moderators. Findings suggest that the effects of social television may be attributable to systematic processing of bandwagon cues.  相似文献

The popularity of social media sites for posting pictures has given rise to a new form of mediated communication: online photo sharing. This article explores motivations for sharing photos online, using the 2-step procedure common in Uses and Gratifications research. Focus groups revealed 42 motivations which were rated in importance by survey respondents (N = 460). Factor analysis revealed 4 classes of gratifications: seeking and showcasing experiences, technological affordances, social connection, and reaching out. These results suggest that photo sharing is driven by social needs and facilitated by interface features, with important implications for theories of technology and user psychology.  相似文献

Doppler-based detection and tracking of humans in indoor environments   总被引:2,自引:0,他引:2  
In this paper, the principles of Doppler processing to detect and track human movers in indoor environments are presented. The topics discussed include the micro-Doppler characteristics of humans, the azimuth, elevation and range tracking of humans using Doppler, spatial and frequency diversity, the effect of walls, and the characteristics of dynamic clutters from non-humans. The studies are supported by simulation and measurement results.  相似文献

This article responds to recent calls for conceptual and methodological refinement, issued by uses-and-gratifications scholars (Rubin, 2009 Rubin, A. M. 2009. “The uses-and-gratifications perspective on media effects.”. In Media effects: Advances in theory and research , 3rd ed. Edited by: Bryant, J. and Oliver, M. B. 165184. New York, NY: Routledge..  [Google Scholar]; Ruggiero, 2000 Ruggiero, T. E. 2000. Uses and gratifications theory in the 21st century. Mass Communication & Society, 3: 337. doi: 10.1207/S15327825MCS0301_02[Taylor & Francis Online] [Google Scholar]), for studying emergent media. Noting that studies on the uses of the Internet have generated a list of gratifications that are remarkably similar to those obtained from older media, it identifies two measurement artifacts—(1) measures designed for older media are used to capture gratifications from newer media; and (2) gratifications are conceptualized and operationalized too broadly (e.g., information-seeking), thus missing the nuanced gratifications obtained from newer media. It challenges the notion that all gratifications are borne out of innate needs, and proposes that affordances of media technology can shape user needs, giving rise to new and distinctive gratifications. A sample of new gratifications and potential measures for those are provided.  相似文献

Alanine aminotransferase (ALT) is the most common and cost effective screening test for asymptomatic liver disease. There is paucity of data on normal ALT among healthy individuals in India. An observational cross sectional study was conducted from January to July 2013 to estimate the upper limit of normal for ALT in healthy south Indian population. Adults undergoing voluntary or pre-employment health screening were included. Those with current and past alcoholism or smoking, acute illness or hospitalization during preceding 12 months, non-steroidal anti-inflammatory or over the counter medication use within a month, current or past intake of herbal medications, any chronic medical illness, abnormal body mass index (BMI), fatty liver in ultrasound, abnormality in haemoglobin, platelet count, blood sugar, creatinine, lipid profile and thyroid function test and positive serology (Hepatitis B, C or HIV) were excluded. A total of 2600 subjects were screened. 344 were included for analysis. Mean age was 35 years in men and 34.83 years in women, with a mean BMI of 22.2 kg/m2 in men and 21.8 kg/m2 in women. The mean ALT in men and women were 21.87 ± 2.9 (97.5th percentile 28 U/L) and 19.35 ± 3.3 (97.5th percentile 24 U/L) respectively. In conclusion, mean and upper limit of ALT (97.5th percentile) in south Indian men was 21.87 and 28 IU/L and women were 19.35 and 24 IU/L respectively. There is a need to re-consider ALT levels in our population for better detection of individuals at risk for liver disease.  相似文献
