The motivational values of social entrepreneurs
2015
The main goal of this research is to understand what kind of motivational values social entrepreneurs have (motivational types of values), how social entrepreneurs prioritize these values (value prioritization) and if these values had an impact on becoming a social entrepreneur and continuing to work as one (impact of the values). The research on social entrepreneurship has largely ignored for-profit social entrepreneurship and the purpose of this research is to contribute to this shortcoming by taking the for-profit entrepreneurs’ perspective. A qualitative case study was chosen as a research method and the empirical data was gathered by interviewing for-profit social entrepreneurs using a…
A comparison of lumbopelvic motion patterns and erector spinae behavior between asymptomatic subjects and patients with recurrent low back pain durin…
2015
Objectives: The purpose of this study was to determine the patterns of lumbopelvic motion and erector spinae (ES) activity during trunk flexion-extension movements and to compare these patterns between patients with recurrent low back pain (LBP) in their pain-free periods and matched asymptomatic subjects. Methods: Thirty subjects participated (15 patients with disc herniation and recurrent LBP in their pain-free periods and 15 asymptomatic control subjects). A 3-dimensional videophotogrammetric system and surface electromyography (EMG) were used to record the angular displacements of the lumbar spine and hip in the sagittal plane and the EMG activity of the ES during standardized trunk fle…
Clinical performance of a highly portable, scanning calcaneal ultrasonometer.
2001
The aim of this study was to establish a normative database, assess precision, and evaluate the ability to identify women with low bone mass and to discriminate women with fracture from those without for a highly portable, scanning calcaneal ultrasonometer: the QUS-2. Fourteen hundred and one Caucasian women were recruited for the study. Among them were 794 healthy women 25–84 years of age evenly distributed per 10-year period to establish a normative database. Of these, 171 aged 25–34 years were defined as the young normal group for the purpose of T-score determination. Precision was assessed within 1 day (short-term) and over a 16-week period (long-term) in 79 women aged 25–84 years. Five…
Electromyographic Studies in Abdominal Exercises: A Literature Synthesis
2008
Abstract Objective The purpose of this article is to synthesize the literature on studies that investigate electromyographic activity of abdominal muscles during abdominal exercises performance. Methods MEDLINE and Sportdiscus databases were searched, as well as the Web pages of electronic journals access, ScienceDirect, and Swetswise, from 1950 to 2008. The terms used to search the literature were abdominal muscle and the specific names for the abdominal muscles and their combination with electromyography, and/or strengthening, and/or exercise, and/or spine stability, and/or low back pain. The related topics included the influence of the different exercises, modification of exercise positi…
Mechanical activity of small and large intestine in normal and mdx mice: a comparative analysis.
1999
The aim of this study was to compare the motor pattern (recorded as changes in intraluminal pressure) of isolated duodenum and proximal colon between dystrophic mdx and normal mice. When duodenal recordings from control preparations were compared with mdx mice there was no significant difference in the spontaneous motor pattern, responses to electrical nerve stimulation or sensitivity to pharmacological agents. Colonic segments from mdx mice showed a more complex motor pattern, consisting of contractions with amplitude and frequency similar to those of controls and by additional contractions with lower amplitude and higher frequency. Moreover, 70% of the colonic preparations from mdx mice d…
The radial artery is larger than the ulnar.
2003
The radial artery is presently widely used as a bypass graft for coronary artery reconstruction. However, the traditional opinion that the ulnar artery is the larger forearm artery has been questioned.The internal diameters of the radial and ulnar arteries were measured at the wrist in postmortem angiograms of 24 cadavers. Differences in mean values of variables between ulnar and radial arteries were analyzed using the Wilcoxon test.The mean diameter of the radial artery was 28% larger than that of the ulnar artery in the right arm (p0.001) and 26% larger in the left arm (p0.001). In the right arm the radial artery was dominant in 20 of 24 cadavers (83%), the ulnar artery in 3 of 24 (13%), …
Is time to joint replacement a valid outcome measure in clinical trials of drugs for osteoarthritis?
2003
The rate of radiographic joint space narrowing is commonly used today as a structural outcome measure in clinical trials evaluating potential disease-modifying drugs in patients with hip osteoarthritis, but this results in a continuous variable. Among the methods proposed to circumvent this problem, it has been suggested that the incidence of total hip arthoplasty (THA) provides a hard outcome measure. It is a dichotomized variable, easy to measure and sensitive to change, with acceptable intrinsic validity. However, because this measure is limited by the variability of factors underlying the decision to perform surgery and the length of waiting lists, it has been suggested that time to ful…
Cultural Values’ Influences on Users’ Preferences for Gamification Techniques
2019
Gamification techniques such as badges, levels, roles, are widely adopted in information systems (IS). Though researchers have noted that cultural values may influence users' usage of IS, there is a lack of research regarding the relationship of cultural values and gamification techniques. Our study aims to contribute to this area. We propose that users' cultural values may influence how they are motivated and further influence their preferences toward specific gamification techniques. In this research in progress, we review cultural values, examine the currently adopted gamification techniques, and then propose how cultural values influence users' preferences toward specific gamification t…
Unpacking the link between family socioeconomic status and civic engagement during the transition to adulthood: Do work values play a role?
2017
We investigated whether the link between family-of-origin socioeconomic status (SES) and civic engagement in young adulthood is mediated by youth’s work values, i.e., the desired characteristics of their current or future jobs. We used data from a Finnish study: 2004 (age 16–18, NT1 = 1,301); 2011 (age 23–25, N T2 = 1,096); and 2014 (age 25–27, NT3 = 1,138). A lower family SES in 2004 was negatively related to youth’s civic engagement in 2014. Lower family SES predicted the importance that youth attached to extrinsic job rewards (e.g., good pay) in 2011, but not the importance of intrinsic job rewards (e.g., learning opportunities). Extrinsic work values, in turn, predicted lower civic enga…
The development of work values during the transition to adulthood : A two-country study
2017
This study addresses the development of work values—the desired characteristics of one's current or future job—during young adulthood. Using two panel studies from Germany (N = 2506) and Finland (N = 1326), we investigated (a) mean-level and rank-order change and stability in work values across three biennial waves (age 20/21 to age 25/26); and (b) the influence of stable background characteristics as well as of major transitions in family and work roles on inter-individual differences and intra-individual changes in work values. Latent measurement models with three work value dimensions showed good fit in both countries: extrinsic (importance of job security and material rewards), intrinsi…
