This study employed structural and treatment analyses to determine factors that contributed to wrist posture safety in a small pharmacy. The pharmacy was located on a university campus and participants were three female pharmacy technicians. These particular employees had experienced various repetitive-motion injuries that resulted in a total of 36 lost days and 161 restricted days. Observers collected observational data on the participants' wrist posture in the presence and absence of an improvised wrist support device that participants placed under the computer keyboard.?Average percentage safe for wrist position with a wrist support was higher for all three participants when compared to wrist position without a wrist support. These results indicated that the participants' wrist posture was considerably safer when the wrist support was present. The structural analysis proved valuable for aiding in the development of an intervention and in identifying variables that were responsible for the participants' wrist posture. 相似文献

Historical contributions of Black youth voices and actions are overlooked from many of the narratives of youth civic engagement (YCE) literature. Specifically, the histories and stories of African American youth in the United States and Black Caribbean youth in the Anglophone Caribbean. The shared socio and political obstacles these particular groups have encountered throughout history shaped similar paths for their involvement in civic society to address many of these social and racial injustices. The article's premise centers on the need for the YCE literature to acknowledge the historical civic contributions African American and Black Caribbean youth have made throughout history. Fundamental historical civic movements that were designed, developed, and supported by Black youth set the tone of Black youth's civic engagement throughout history. These were shaped and contextualized by three specific macrosystem influences (political suppression, institutional racism, and cultural oppression). When YCE scholars begin to make greater meaning of the foundations and critical work developed by Black youth civic activists, a more comprehensive field emerges. With the acknowledgment and inclusion of civic contributions created and implemented during historical eras, more profound meaning is gained of civic engagement among communities and people who have generally been disenfranchised. Coming to terms with their civic legacies developed from racial injustices provides a more comprehensive depiction of civic engagement as a field and body of literature. 相似文献

Objective. Sociologists of technology propose that not only a technological artifact, as such, but also patterns of usage should be considered when studying the social implications of technologies. Accordingly, we explore how people's online activities are influenced by users' socioeconomic status and context of use. Methods. We analyze data from the Allensbacher Computer and Technology Analysis (ACTA) 2004 survey with uniquely detailed information about people's Internet uses and context of usage to explore this relationship. Results. Findings suggest that high‐status and low‐status individuals cultivate different forms of “Internet‐in‐practice.” High‐status users are much more likely to engage in so‐called capital‐enhancing activities online than are their less privileged counterparts. Conclusion. Results suggest differential payoffs from Internet use depending on a user's socioeconomic background. Digital inequalities might be mitigated by improving people's Internet equipment and digital experience, but they do not account for all the status differential in use. 相似文献

In this paper, a regression semi-parametric model is considered where responses are assumed to be missing at random. From the empirical likelihood function defined based on the rank-based estimating equation, robust confidence intervals/regions of the true regression coefficient are derived. Monte Carlo simulation experiments show that the proposed approach provides more accurate confidence intervals/regions compared to its normal approximation counterpart under different model error structure. The approach is also compared with the least squares approach, and its superiority is shown whenever the error distribution in the simulation study is heavy tailed or contaminated. Finally, a real data example is given to illustrate our proposed method. 相似文献

Through a survey of organizational stakeholders (N = 660), this study contributes to the understanding of nonprofit public relations in three key areas. First, a new five-factor scale to measure perceptions of the relationship cultivation strategies of stewardship was tested. Second, group differences between organization stakeholder types were explored. Third, a new working model that extends previous organization-public relationship (OPR) models to include variables of loyalty and behavioral intentions was advanced. Findings revealed theoretical, measurement, and practical applications. 相似文献

The potential indirect effect of observed maternal sensitivity at 5 months on the development of infants' behavioral regulation of emotion from 5 to 10 months (i.e., distraction and maternal‐orientation behaviors) via infant's vagal withdrawal was investigated (N = 230). Results indicated that maternal sensitivity at 5 months was not directly associated with behavioral regulation at 10 months. However, greater maternal sensitivity at 5 months was associated with greater vagal withdrawal at 10 months, after controlling for vagal withdrawal at 5 months. Further, vagal withdrawal at 10 months was associated with greater orientation toward the mother at 10 months, after controlling for 5‐month orientation behaviors. The indirect effect of maternal sensitivity on maternal‐orientation behaviors was significant, suggesting that infant's vagal withdrawal may be one potential mechanism through which maternal sensitivity is related to behavioral regulation. 相似文献

On the basis of three empirical studies Fitts' Law was refined for bivariate pointing tasks on large touch screens. In the first study different target width parameters were investigated. The second study considered the effect of the motion angle. Based on the results of the two studies a refined model for movement time in human-computer interaction was formulated. A third study, which is described here in detail, concerns the validation of the refined model. For the validation study 20 subjects had to execute a bivariate pointing task on a large touch screen. In the experimental task 250 rectangular target objects were displayed at a randomly chosen position on the screen covering a broad range of ID values (ID= [1.01; 4.88]). Compared to existing refinements of Fitts' Law, the new model shows highest predictive validity. A promising field of application of the model is the ergonomic design and evaluation of project management software. By using the refined model, software designers can calculate a priori the appropriate angular position and the size of buttons, menus or icons. 相似文献

This paper presents a mixed-method approach to measuring the functioning of Safe Schools/Healthy Students (SS/HS) Initiative partnerships. The SS/HS national evaluation team developed a survey to collect partners’ perceptions of functioning within SS/HS partnerships. Average partnership functioning scores were used to rank each site from lowest to highest. Sites with the most favorable perceptions of partnership functioning were defined as having average scores in the top 10% (n = 10) and sites with the least favorable perceptions of partnership functioning were defined as having average scores in the bottom 10% (n = 10). Qualitative data for these 20 sites were inductively open coded for emergent themes and analyzed for patterns using grounded theory approach. Six themes emerged that distinguished sites reporting the most favorable and least favorable perceptions of partnership functioning: partner engagement, facilitators, barriers, shared decision making, partnership structure, and sustainability. Sites reporting the most favorable perceptions of partnership functioning effectively utilized collaboration processes that facilitate coalition building, such as shared decision making, effective communication, and developing a clearly defined structure. Qualitative themes from this analysis provide evidence of validity for the partnership functioning scale used and illustrate distinguishing features between sites with the most favorable and least favorable perceptions of partnership functioning. 相似文献
