This 9 month prospective study, conducted at the US Army Sergeants Major Academy (USASGMA), examined the association of selected psychological variables (e.g., measures of tension/anxiety, sleep disturbance, Type A behavior pattern) with injury occurrence and physical performance in 126 soldiers. ANOVA and logistic regression analyses revealed significant relationships between: 1) Traumatic injury occurrence and mean tension/anxiety scores, 2) Mean self-reported sleep disturbance scores and traumatic injury occurrence, 3) The Type A behavior pattern (abbreviated Jenkins Activity Survey) and number of sit-ups repetitions completed in 2 minutes, one component of the Army Physical Fitness Test (APFT), 4) The Type A behavior pattern and total score APFT. No significant associations were found for mean tension/anxiety scores and overuse injuries, or Type A behavior pattern and two mile run time or number of push-up repetitions completed in 2 minutes. These data suggest traumatic injury occurrence is influenced by tension/anxiety and disturbances in sleep habits. Additionally, individuals with higher Jenkins Activity scores (characteristic of the Type A behavior pattern) perform better physically.  相似文献

This paper puts forth arguments regarding the occurrence of state Sunday closing laws and reports statistical estimates that predict the occurrence of those laws in 1970 and 1984. Along with other socio-economic variables, two labor market activities are found to be significant determinants of Blue laws. Membership in labor unions is found to have a positive declining influence on the laws; female labor market participation is found to have a negative but growing influence.  相似文献

This study aims to preliminary explore the work related and individual factors that contributed to the occurrence of low back pain (LBP) that affected work activities of Personal Care Workers (PCWs). A cross-sectional study was conducted to 36 PCWs in an old age home of Hong Kong. The study is divided into three parts: 1) a questionnaire to document the workload exposure factors and the musculoskeletal symptoms survey of the PCWs, 2) work posture evaluation; and 3) an evaluation of the physical fitness and lifting capacity of the PCWs. Univariate analyses were used to explore the risk factors associated with LBP that affected work activities. The results indicated that individual physical profile and lifting capacities did not contribute to occurrence of low back pain at work. For the work demand factors, the perceived physical demands in lifting and lowering heavy objects, awkward sustain neck and back postures, loading on the back, and perceived effort of cleaning task contributed to the occurrence of LBP. For the physical environment factors, thermal stress and improper ventilation were associated with the occurrence of LBP cases. For the individual factor, LBP cases were associated with workers' self perceived muscular effort, and perceived risk of mental illness in response to work requirements.  相似文献

Medication error is an issue that no hospital is immune from, leading to 7,000 deaths and 1.3 million patient injuries each year. The purpose of this study was to decrease the risk and occurrence of medication errors by analyzing the hospital pharmacy. Task analyses were performed and it was found that communication, expectation, and procedural issues were leading to the occurrence of the most common type of medication error in the pharmacy. Recommendations were made to improve the process and reduce the occurrence of this type of error.  相似文献

Stormwater retention ponds in urbanizing catchments are constructed to collect and treat runoff from impervious surfaces. Amphibians often inhabit retention ponds, which may partly offset the loss of natural wetlands resulting from urbanization. We investigated the use of retention ponds by frogs in a rapidly-urbanizing region of south-eastern Australia to (1) determine the habitat attributes associated with individual species, and (2) recommend specific wetland design criteria to enhance populations of frog species in the region and in other urbanizing areas throughout their distribution. We detected nine species of frogs during calling surveys at 30 retention pond sites in Greater Melbourne, 2008?C2010. There were contrasting differences in habitat associations among five species for which we produced regression models of abundance or occurrence. The mean abundance of Crinia signifera increased with site area, whereas Limnodynastes dumerilii was associated with smaller sites. The occurrence of L. dumerilii was positively associated with waterbody shore depth, whereas L. peronii and L. tasmaniensis were associated with shallow shores. Two species were positively associated with time since construction or since dredging of a site, whereas the occurrence of L. dumerilii decreased with site age. Aquatic vegetation at a site was important for the occurrence of L. peronii and Litoria ewingii. There was evidence for a positive effect of aquatic connectivity on the occurrence of Limnodynastes peronii, which emphasizes the importance of riparian corridors in urban settings. These results highlight the contrasting differences in habitat associations among species in the region. We recommend that retention ponds in our region and elsewhere be constructed or enhanced to include specific habitat attributes that were found to be associated with different amphibian species. We recommend long-term monitoring at sites to determine whether retention ponds augment existing frog populations or contribute to declines.  相似文献

The occurrence of sibling incest is underrecognized, and its impact is debated. Professionals may be inadequately sensitized to its occurrence since it is considered less traumatic to victims than other forms of incest and assigning responsibility in such contact between minors is difficult. Survivors may be unlikely to reveal such a history because of guilt and shame. Four case presentations of females who expereinced sibling incest illustrate problem areas, including issues of enforced secrecy, interpersonal power differentials, influences on sexual development, individual aftereffects, disturbance in family dynamics, and genderbased differences in relationship styles. Recommendations for identification and treatment are included.  相似文献

This article presents an evaluation study of a case management method for child protection services, the Delta Method for Family Supervision, in terms of supervision order duration and occurrence and duration of out-of-home placements. Additionally, case and case manager characteristics were examined. Data was collected about 224 cases, 58 case managers and 30 team managers of all 15 offices of the Child and Youth Protection Services in the Netherlands. In all cases the Delta Method was applied. Data were obtained by interviews, questionnaires and case files. Multi-level analysis was performed to study the influence of independent variables on supervision order duration, and the occurrence and duration of out-of-home placements. Case characteristics related to 87% of the differences in the duration of supervision order, case manager characteristics to 13% of the differences. Some case manager characteristics about applying the Delta Method were significantly related to shorter duration of the supervision order and the occurrence and duration of out-of-home placement. Case characteristics also showed strong relations. Together with the more general aspects of case management supported by this study, such as a one family and one worker approach, this contributes to a more effective practice of case management for child protection services.  相似文献

The term ‘thorarche’ is proposed for the first seminal ejaculation in boys. A retrospective study on thorarche with 142 male, undergraduates (aged 18–21 years) indicated that 80.3% remembered their thorarche. Less than a third had had any instruction about its occurrence compared to the 91.7% of 133 female undergraduates who were instructed about menarche. The cause of thorarche for 92.4% was sexual, it occurred in sleep for only 25.6%. Approximately 43% felt thorarche made them aware that a milestone in masculinity had been attained but only 12.4% told anyone about it while just under half (41.7%) tried to hide its occurrence. In the case of the girls, 46.2% reported that menarche made them feel that a milestone in female development was attained and 49.1% told other girls about its occurrence. Of those who could recall the time of year of their thorarche a strong seasonal effect was apparent, the highest incidence occurred in the spring (40.6%) and summer (34.8%) sharply decreasing in the autumn (15.9%) and winter (8.7%). This was in contrast to menarche which was evenly distributed between spring, summer, autumn and winter. Unlike menarche, there was no evidence for a secular trend in thorarche.  相似文献

Intimate partner violence often includes economic abuse; unfortunately, economic abuse has not been examined sufficiently in the literature. Using longitudinal data from the Fragile Families and Child Wellbeing Study, this paper examined the occurrence of and changes in economic abuse and physical violence over time and how these factors influenced union formation. The results indicated that the prevalence of economic and physical abuse increased over time, particularly for economic abuse. The changes in union formation for cohabiting and visiting mothers were quite substantial over time. Regression analyses indicated that, over time, the occurrence and the increase of economic abuse and the increase of physical violence were significantly and negatively associated with the likelihood of stable union formations such as marriage and cohabitation. Policy and research implications are discussed.  相似文献

Urbanization and other land cover changes have been particularly detrimental to wetlands throughout the planet. One wetland specialist that may be sensitive to land cover changes surrounding wetlands is the round-tailed muskrat (Neofiber alleni; hereafter RTM). The RTM is a wetland obligate rodent that appears to have declined over the last half century and is a species of concern in Florida, where it is a near endemic. To determine if urbanization or other land cover influenced the distribution of RTMs we took a multi-scaled approach to examine the occurrence of RTMs and their associated vegetation in North-Central Florida. We detected RTMs on 19 of 72 sample plots and used a Classification And Regression Tree (CART) to determine that dogfennel (Eupatorium capillifolium) was negatively associated with RTMs and maidencane (Panicum hemitomon) was positively associated with their occurrence on sampling plots. Examining the influence of landscape composition for 2 km surrounding our plots we found that RTM occurrence was negatively related to urban land cover. Further, we found that dogfennel increased and maidencane decreased as urbanization increased in the surrounding landscape. Our research suggests that conservation of RTMs and their associated vegetation should focus on limiting urban sprawl at least within 2 km of wetlands.  相似文献

This study uses the characteristics of male and female partners within adolescent relationship pairs drawn from the National Longitudinal Study of Adolescent Health to predict the occurrence of intercourse within relationships. Most analyses are based on a sample of 724 relationship pairs. The sample was ethnically diverse: 56% White, 20% Black, 14% Hispanic, and 10% Asian, Pacific Islander, or Other. Male partners on average were 17.5 years in age and females were 17.0. Predictors of intercourse included virginity status when entering the relationships, desire to have sex early in relationships, family‐ and school‐related risk indicators, attitudes regarding the pros and cons of having sex, and other risk indicators, such as delinquency and drinking. Findings demonstrate that the characteristics of both sexes influence intercourse occurrence within relationships.  相似文献

Land-use planning to conserve habitat for area-sensitive forest birds   总被引:2,自引:0,他引:2  
Models predicting the occurrence of area-sensitive bird species in forests were developed from bird survey data from 499 forests in Prince George's County, Maryland. The predicted probabilities of occurrence for species were integrated with forest cover data for the County in a Geographic Information System (GIS). This information was used in combination with local zoning and forest conservation requirements to develop a preliminary forest conservation plan for the watershed of the Western Branch of the Patuxent River. We identify forests patches most likely to support breeding populations of area-sensitive birds, and use the GIS to devise ways to consolidate and link them. Forests that do not contribute significantly to the integrity of these priority forests are designated as sites in which development could occur. The resulting conservation plan will maintain and enhance breeding habitat for area-sensitive forest birds, while still allowing for additional development as human populations increase.  相似文献

Plants in cities must cope with various anthropogenic environments that differ from surrounding landscapes. Moreover, the differences in biotic and abiotic conditions among these habitats filter species with suitable traits and niche requirements. Here we aim to identify those attributes that promote species occurrence across and within urban habitat types of large cities. Species composition of spontaneously occurring vascular plant species was recorded in 1-ha plots in seven different urban habitat types in each of 32 European cities. Each species was characterized in terms of dispersal type, growth form, height, seed bank longevity, seed mass, selected leaf traits and ecological indicators including Ellenberg indicator values, Grime’s life strategies, and immigration pathways using information from available species-trait databases. For each species, total frequency of occurrence across all plots and habitat frequency of occurrence across plots of given habitat types were calculated and regression trees were used to relate them to traits and ecological indicators. The most frequently occurring species in the cities tended to be human-dispersed, nutrient-demanding plants that prefer drier to mesic soil conditions. These species do not possess the S-strategy and usually produce seeds of low mass forming short-term persistent seed banks. Habitat-specific responses were also revealed, indicating the effects of between- and within-habitat heterogeneity on trends in species performance in cities. Such patterns can be overlooked when differences in species occurrences in particular urban habitat types are not considered; thus, habitat-specific responses can resolve inconsistencies found when whole urban floras are analysed as a whole.  相似文献

This article presents a study on the perception of fear related to the use of three different types of urban furniture, qualitatively evaluated based on interviews while people were using them in the city of Porto Alegre, Brazil: the bus shelter, the playground, and the gymnastic equipment. The fear related to the lack of safety of the urban space was associated with the use of the three types of products. The fear experienced by the use of the playground and the bus shelter was related to the occurrence of accidents, since both products are often unsafe and do not fulfill ergonomic parameters. The fear experienced from the use of the gymnastic equipment is related to the possibility of incorrect use of the product and the occurrence of harassment. Both ergonomics and emotion are important aspects to be considered in design, in order to make the use of social/ collective products a pleasant experience.  相似文献

The Facial Action Coding System (FACS) (Ekman & Friesen, 1978) is a comprehensive and widely used method of objectively describing facial activity. Little is known, however, about inter-observer reliability in coding the occurrence, intensity, and timing of individual FACS action units. The present study evaluated the reliability of these measures. Observational data came from three independent laboratory studies designed to elicit a wide range of spontaneous expressions of emotion. Emotion challenges included olfactory stimulation, social stress, and cues related to nicotine craving. Facial behavior was video-recorded and independently scored by two FACS-certified coders. Overall, we found good to excellent reliability for the occurrence, intensity, and timing of individual action units and for corresponding measures of more global emotion-specified combinations.  相似文献

Through the rapid expansion worldwide of impervious areas and habitat fragmentation, urbanization has strong consequences that must be understood to efficiently manage biodiversity. We studied the effects of urbanization on flower-feeding insects by using data from a citizen science program in the Parisian region. We analysed the occurrence of insects from 46 different families on flowers of different morphologies, using landscape indices in buffer areas from a 100-m to a 4000-m radius around 1194 sampled sites. Our aims were to determine (i) how the proportion of impervious area around sampled sites affected the occurrence of flower-feeding insect families and at which landscape scales impervious area calculations best predicted these occurrences; (ii) the effect of corolla shape variables on insect family occurrences. Twenty-one families were negatively impacted by increasing proportion of impervious areas (urbanophobic) and 3 were positively impacted (urbanophilic). Urbanophobic families were most affected by the proportion of impervious areas when it was estimated within buffers of 200-m to 1400-m radii, depending on the family. Notable losses of urbanophobic families were detected at less than 50% of impervious areas, which highlights the threat to the diversity of flower-feeding insects posed by urban sprawl. Corolla shape variables were the variables most often significantly implicated in the occurrence of insect families. Urbanophobic families were negatively affected by the tubular shape of flowers, and tubular corollas were found more often in urbanized areas. These results suggest that flora management might be a key component for the conservation of insect diversity in cities.  相似文献
