Eight hundred employees from across the U.S. work force participated in a detailed 13-month longitudinal study of involvement learning and development activities. A new model was posited tested which hypothesized sequence as follows: worker age --> individual situational antecedents perceived benefits participation self-efficacy for attitudes toward intentions to participate participation. The results depict person who is oriented employee having activities before, perceiving themselves...
Abstract Anthropologists frequently use musculoskeletal stress markers to reconstruct past activity patterns. Yet, researchers have called into question the reliability of muscle marker measurements in part because body size and age affect scores. In this study, author examined an aggregate upper limb determine if after controlling for effects age, one could patterns a prehistoric Amerind population. Analyses were made sample 102 (43 males, 59 females) central California Amerinds. Muscle...
A mechanistic understanding of the pathology psychiatric disorders has been hampered by extensive heterogeneity in biology, symptoms, and behavior within diagnostic categories that are defined subjectively. We investigated whether leveraging individual differences information-processing impairments patients with post-traumatic stress disorder (PTSD) could reveal phenotypes disorder. found a subgroup PTSD from two independent cohorts displayed both aberrant functional connectivity ventral...
Musculoskeletal markers are frequently used to reconstruct past lifestyles and activity patterns. Yet, the reliability of muscle marker measurements has been called into question because they allegedly fail correlate with cross-sectional properties exercise patterns, confounded by body size. In this study, principle aggregation was sum over 7 insertion sites (4 humeral, 2 radial, 1 ulnar) examine effects on them size, age, sex, properties. Analyses were made a sample 91 (66 males, 25...
Purpose – The purpose of this paper is to introduce new measures stereotypical beliefs about older workers' ability and desire for learning development test relationships with key antecedents outcomes. Design/methodology/approach In a sample workers over 40 years age from across the US workforce, two‐wave survey study was unique in that it examined stereotypes held by aging themselves relation their own behavior. Findings psychometric qualities scales were positive findings tied stereotype...
Abstract This study examined six musculoskeletal stress marker (MSM) scores that showed reverse sex differences in the previously published research. MSM often differ by within a population. Most females have lower than do males; however, occur. If are culturally specific, then these more likely caused activity patterns biology. Yet, if same show trends multiple populations, perhaps reversals may be result of biological differences, such as hormonal and body size, or methodological reasons,...
Abstract Musculoskeletal markers are frequently used to reconstruct past lifestyles and activity patterns. Yet the reliability of muscle marker measurements has been called into question because they may be confounded by body size. In this study, an aggregate variable was calculated using 20 insertion sites (14 femoral, 6 tibial), I examined their effects on lower limb size (as a proxy for size), age, sex. Analyses were made sample 77 (57 males, females) Native British Columbians...
Abstract This study used an aggregate measure of robusticity (based on humeral areal and inertial cross‐sectional components) to test the hypothesis that rowing oceans led more robust humeri than did rivers or not at all. Results confirmed male ocean‐rowers had river‐rowers nonrowers. However, although females from ocean‐rowing populations row, they averaged non‐ocean‐rowing populations. Males greater females. The populations, therefore, does seem be due solely bone remodeling resulting...
Rosen and Jerdee's (1976a) classic study on age discrimination, conducted over 25 years ago, was replicated in the present study. In original study, participants rated older targets as being less desirable suitable a variety of work‐related scenarios. contrast, current younger similarly qualified for promotion, training, hiring. The discontinuity between results 2 studies is discussed, explanations involving both social change methodological factors are suggested.
Objective. This study aimed to determine whether BMI increases knee pain as measured from self-reported surveys even when controlling for OA severity by osteophytes and joint space narrowing visible on X-rays. Methods. Data available through the Osteoarthritis Initiative (OAI) were analysed, which included a sample of 4769 individuals, answer above question regarding OA, excess weight pain. was assessed baseline X-rays right knees that scored composite quasi-Kellgren Lawrence grade. Weight...
Abstract This study uses two prehistoric Amerindian populations of hunter‐gatherer subsistence patterns to determine whether levels sexual dimorphism in humeral bilateral cross‐sectional asymmetry are related sex‐specific differences activities among these populations. Results confirmed that males the California Amerind population who engaged more unimanual spear hunting and warfare were asymmetrical than their female counterparts bimanual grinding acorns. also British Columbian rowed (using...
Purpose: To measure the sensitivity of deformable image registration to noise. Deformable can be used map organ contours and other treatment planning data from one CT another. These studies acquired with either conventional fan‐beam systems or more novel cone‐beam techniques. However, images have higher noise levels than CT, which might reduce accuracy. We investigated effect quality differences on CTs simulated Method: Our study three for each five prostate patients. Each was contoured by...
The present study examines a sample of 105 hunter–gatherer California Amerinds to determine whether fibrocartilaginous musculoskeletal stress markers (MSMs) are better for activity reconstructions than fibrous MSMs. Femoral and humeral head diameters were measured as proxies body size. All data analysed statistical significance using non-parametric tests. Fibrous MSMs the left deltoideus, right hip adductors, tibial soleus correlate positively with size proxies. For MSMs, teres minor...
Fatigue in individuals with multiple sclerosis (MS) may be exacerbated by poor cardiovascular fitness. Although aqua aerobic exercise is often recommended, little research has been conducted on the efficacy of improving fitness patients MS. The purpose this case report to describe changes and fatigue for 2 people MS following an aerobics class.The participants were females, both over 10 years mild disability. Participant A (40 old EDSS = 2.5/10) reported fatigue, numbness her hands feet,...
Real‐time tumor targeting involves the continuous realignment of radiation beam with tumor. offers several advantages such as improved accuracy treatment and reduced dose to surrounding tissue. Current limitations this technique include mechanical motion constraints. The purpose study was investigate an alternative scenario using a moving average algorithm. algorithm, suitable averaging period, accounts for variations in position, but respiratory induced target position about are ignored...
