Community-dwelling veterans at risk for suicide may be in contact with a variety of providers in agency-based settings that offer health and human services. The study aim is to describe the perspective of agency-based clinical and community providers who may come into contact with veterans in need of suicide prevention services and to examine the nature of their personal and professional relationships to individuals at risk for suicide among this sample.

This study reports on qualitative data from a sample of Veterans’ Affairs (VA) and community providers serving veterans and military families in one Midwestern state (N = 70). Providers completed a survey assessing exposure to suicide, including contact with and relationship to someone suicidal, and organizational characteristics of the providers’ employing agencies. Semi-structured interview questions probed for the nature of how they would react with suicidal individuals. Most providers (94%) had some prior contact with someone who was suicidal, and nearly three quarters (77%) knew someone who had died by suicide. Providers reported powerful emotional responses of sadness and remorse to suicidal experiences. While these providers interact with veterans and military families as part of their jobs, they may have their own history of being exposed to suicide, both professionally and personally.  相似文献

This study investigated the influence of emotion on toddlers' prosocial behavior in instrumental helping tasks with an unfamiliar adult. The goals were to examine whether early prosocial behavior was affected by (1) the adult's expressions of sadness (in contrast to a neutral expression) as a cue of need and (2) toddlers' emotion understanding. Thirty‐five 18‐ to 20‐month‐olds participated in eight trials in which an experimenter either indicated need for assistance (experimental condition) or did not (control). In addition, the experimenter expressed either sadness or neutral affect in each trial. Toddlers' emotion understanding was assessed using maternal reports of children's emotion words. The experimenter's emotional expression alone was not associated with prosocial behavior, but toddlers helped more in experimental than control conditions. However, toddlers with larger emotion word vocabularies were marginally more prosocial when the experimenter expressed sadness, and girls provided more assistance than boys in experimental conditions. These findings highlight the complex influences of emotion on early prosocial motivation.  相似文献

Relationships between species and their environment are a key component to understand ecological communities. Usually, this kind of data are repeated over time or space for communities and their environment, which leads to a sequence of pairs of ecological tables, i.e. multi-way matrices. This work proposes a new method which is a combined approach of STATICO and Tucker3 techniques and deals to the problem of describing not only the stable part of the dynamics of structure–function relationships between communities and their environment (in different locations and/or at different times), but also the interactions and changes associated with the ecosystems’ dynamics. At the same time, emphasis is given to the comparison with the STATICO method on the same (real) data set, where advantages and drawbacks are explored and discussed. Thus, this study produces a general methodological framework and develops a new technique to facilitate the use of these practices by researchers. Furthermore, from this first approach with estuarine environmental data one of the major advantages of modeling ecological data sets with the CO-TUCKER model is the gain in interpretability.  相似文献

Brazil is currently recognized as the 10th largest producer of castings, and the city of Cláudio, MG is known worldwide as the "Greatest foundry and metallurgical pole in Latin America", with more than 80 companies. However, this large number of enterprises and increasing investments in product development has demanded an increase in manpower and working hours of workers in the sector, proportionally increasing the incidence of occupational related health problems like RSI (repetitive strain injury), WMSDs (work-related musculoskeletal disorders) and industrial accidents. This article aims to characterize the industry from previously conducted case studies to relate the main causes of occupational diseases and outline possible interventions through design, showing how this tool can contribute to improve the working environment, workplace, tools and equipment through ergonomics adjustments.  相似文献

Abstract

The relationship between three different performance measures and burnout was explored in 20 Dutch Intensive Care Units (ICUs). Burnout (i.e. emotional exhaustion and depersonalization) proved to be significantly related to nurses' perceptions of performance as well as to objectively assessed unit performance. Subjective performance measures relate negatively to burnout levels of nurses, whereas an objective performance measure relates positively to burnout. Furthermore, subjectively assessed personal performance (i.e. personal accomplishment) is more strongly related to burnout than subjectively assessed unit performance. A model test of the relationship between both types of subjective performance and burnout reveals that nurses' perception of unit performance is indirectly related to burnout through perception of personal performance. This model holds similarly for objectively well- and poor-performing ICUs.  相似文献

Ethnic residential concentration is often found to hamper immigrants’ majority language proficiency. However, there are still several gaps in our understanding of the relationship between ethnic concentration and ethnic minorities’ language practices. This study examines the extent to which ethnic concentration also constrains immigrants’ majority language use, whether contact with natives and co-ethnics mediates these relationships, and whether ethnic concentration relates to second-generation minorities’ minority language proficiency. Structural equation models on data for people of Turkish and Moroccan origin living in the Netherlands (N = 2163) showed that ethnic concentration is indirectly related to weaker majority language proficiency and less majority language use through contact with natives and co-ethnics. For second-generation minorities, ethnic concentration is related to better minority language proficiency.  相似文献

The aim of this paper was to validate the Brazilian-Portuguese version of the Satisfaction With Life Scale (SWLS), presenting evidence of its reliability and construct and criterion-related validity. A large Brazilian sample (2,180 participants), from five different populations (undergraduate and high school students, general population, elementary school teachers, and physicians), was considered. The results confirmed the single factorial structure and reliability (0.77 < Cronbach’s α < 0.88, mean α = 0.81) of the SWLS. Supporting its criterion-related validity, the SWLS correlated positively with positive affect and negatively with both negative affect and psychological distress across all five samples. The findings indicate that the Brazilian-Portuguese version of the SWLS is a valid instrument to use with diverse Brazilian samples.  相似文献

We prove weak and strong laws of large numbers for coherent lower previsions, where the lower prevision of a random variable is given a behavioural interpretation as a subject's supremum acceptable price for buying it. Our laws are a consequence of the rationality criterion of coherence, and they can be proven under assumptions that are surprisingly weak when compared to the standard formulation of the laws in more classical approaches to probability theory.  相似文献

Children with alleged child sexual abuse (CSA) need to be assessed systematically. The use of validated instruments during the assessment, like the Child Sexual Behavior Inventory (CSBI), could add diagnostic value. We aim to assess the diagnostic utility of the CSBI to differentiate between sexually abused and non-abused children. We conducted a systematic review. We searched the electronic databases MEDLINE and PsychInfo for studies comparing CSBI scores in sexually abused children and non-abused children (2–12 years old). Two independent reviewers extracted data and assessed the methodological quality. We included 7 (out of 1048) articles. The CSBI total scores were significantly higher in CSA-victims compared with non-abused children (in case–control settings). However, in children with suspected CSA, the results were ambiguous. One study reported significant differences. Another study reported weak diagnostic ability for the CSBI-3 in children with suspected CSA (a sensitivity and specificity of 0.50, with a positive predictive value of 0.28, and a negative predictive value of 0.72). Research on the diagnostic utility of the CSBI for suspected CSA is limited and shows disappointing results. Until more research is done, the CSBI should not be used on its own to differentiate between sexually abused and non-abused children.  相似文献
