Child sexual abuse is one of the main types of abuse still to be addressed within the field of education, yet the education system itself can serve as a primary tool for its prevention. A better understanding of teachers’ knowledge and beliefs about child sexual abuse will allow us to establish key starting points from which to utilize the system for prevention. Four hundred and fifty teachers participated in this study, completing a questionnaire regarding their knowledge and beliefs about child sexual abuse. The study revealed that over half the teachers, 65.3% (n = 294), had never received any type of training in child sexual abuse education and that the majority were not familiar with methods of identifying child sexual abuse, 90.7% (n = 279). Various mistaken beliefs were identified among the participating teachers, such as pathological profiles of abusers, that the vast majority of child sexual abuse implies violent behavior, and that there cannot be abusers the same age as the victim. These results indicate that knowledge deficiencies do exist about child sexual abuse among teachers and highlight the need for training in this field.  相似文献

Middle school is the appropriate time for students to begin exploring careers and improving self‐efficacy; however, empirically supported career and college readiness interventions for U.S. middle school students are limited. Examining the effect of an intervention that combined a virtual experience and a local college visit on middle school students (99 girls, 74 boys), the authors found that participating students had higher levels of college and career self‐efficacy than did nonparticipating students. The study shows that a workshop of the online Florida CHOICES program coupled with a campus visit increased middle school student career and college self‐efficacy. Future research should include longitudinal studies and use of diverse populations to improve generalizability of study results.  相似文献

ABSTRACT

A majority of adults with serious disabilities are cared for in the home by family members. Guided by an ecological framework, this article presents the findings of a literature review of research on family caregiving and family support for adults with disabilities. This review included 33 research studies published between 2000 and 2015 focused on three disabilities: Developmental disabilities, serious mental illnesses, and traumatic brain injury. A synthesis of the findings underscores the critical role that family caregivers occupy in addressing the needs of their loved one with a disability; however, the needs of the caregiver are insufficiently met by existing service approaches. A better understanding of the unique needs and strengths of the family support context of caregivers and care recipients is needed, giving greater attention to ethnic, racial, and cultural considerations in future research.  相似文献

The goal of this study is to analyse the differences in attitudes towards habitual modes of transportation among users of public and private transportation. The explanatory capacity of attitudes when determining the mode choice, along with the structural and sociodemographic factors, are also verified. The study was performed in three Spanish cities with 742 participants. The results revealed that cars are better rated than public modes of transportation in the attributes associated with immediate advantages (i.e., speed and availability) and convenience. Subways are highly rated in both immediate and deferred advantages (environment, safety, cost and health). Buses are the mode rated the lowest of the three. Using logistic regression, it was verified that the variance explained by a model that includes attitudes (R2 = .639) is higher than the variance explained by a model based solely on variables related to infrastructures (R2 = .489). The discussion of these results includes proposals aimed at decreasing car use.  相似文献

The main models of machine learning are briefly reviewed and considered for building a classifier to identify the Fragile X Syndrome (FXS). We have analyzed 172 patients potentially affected by FXS in Andalusia (Spain) and, by means of a DNA test, each member of the data set is known to belong to one of two classes: affected, not affected. The whole predictor set, formed by 40 variables, and a reduced set with only nine predictors significantly associated with the response are considered. Four alternative base classification models have been investigated: logistic regression, classification trees, multilayer perceptron and support vector machines. For both predictor sets, the best accuracy, considering both the mean and the standard deviation of the test error rate, is achieved by the support vector machines, confirming the increasing importance of this learning algorithm. Three ensemble methods - bagging, random forests and boosting - were also considered, amongst which the bagged versions of support vector machines stand out, especially when they are constructed with the reduced set of predictor variables. The analysis of the sensitivity, the specificity and the area under the ROC curve agrees with the main conclusions extracted from the accuracy results. All of these models can be fitted by free R programs.  相似文献

Glaser and Strauss reported decades ago that in order for a person to be treated as dying, he/she must be defined as dying. Defining nursing home residents as "dying" can be complicated because most residents are in advanced old age with multiple chronic conditions. Using a social construction theoretical framework, this study looks at the step before the declaration of dying, that is, the consideration of the possibility of dying. This qualitative study is a secondary analysis of prospective data collected during 16 months of fieldwork on behalf of 45 nursing home residents whose health was considered declining. The purpose of this paper is to build understanding about the social construction of "possible dying" by reporting triggers that can call the question of possible dying and stimulate a discussion about the nursing home resident's status, prognosis, care options, and preferences. These triggers include: Health status decline; noncompliance with diet or medications; available medical interventions not being well suited for the residents; and family consideration of an out-of-town trip. The paper also reports barriers (family, staff, and disease process) and facilitators to calling the question of possible dying, including families having a sense of treatments they would like to avoid and having the opportunity to talk through options. Findings are discussed in light of basic assumptions of social construction. Implications for social workers include helping residents, families, and staff anticipate and address the possibility of dying, and to reflect these discussion in care plans, as well as the need to be available to help residents and family members with psychosocial issues related to living and dying in the nursing home setting, including the profound issues that can be provoked or exacerbated by resident health status decline and possible dying.  相似文献

Most automobile insurance databases contain a large number of policyholders with zero claims. This high frequency of zeros may reflect the fact that some insureds make little use of their vehicle, or that they do not wish to make a claim for small accidents in order to avoid an increase in their premium, but it might also be because of good driving. We analyze information on exposure to risk and driving habits using telematics data from a pay‐as‐you‐drive sample of insureds. We include distance traveled per year as part of an offset in a zero‐inflated Poisson model to predict the excess of zeros. We show the existence of a learning effect for large values of distance traveled, so that longer driving should result in higher premiums, but there should be a discount for drivers who accumulate longer distances over time due to the increased proportion of zero claims. We confirm that speed limit violations and driving in urban areas increase the expected number of accident claims. We discuss how telematics information can be used to design better insurance and to improve traffic safety.  相似文献

ABSTRACT

This is the first published account of state administrative code variations in nursing home social worker qualifications. It is important to review state codes because the majority of nursing homes in the U.S. have fewer than 121 beds and therefore are not required by the federal government to employ at least one full-time qualified social worker. States have the option of extending the federal regulations to homes with 120 or fewer beds, or strengthening the federal requirements in other ways. Findings indicate enormous variation in state requirements for qualifications of nursing home social workers, and even when states define a qualified nursing home social worker (not all do), they often exempt facilities from employing one. Seven states were found to be out of federal compliance. Research describing the qualifications of people employed in nursing home social services is called for, as well as research documenting effective psychosocial interventions, especially as they relate to resident quality of life. Ten recommendations for enhancing nursing home social work services are included.  相似文献
