This study investigated the relationship between guardian certification requirements and guardian sanctioning in the state of Washington. A total of 377 files were examined. Findings show that 52.4% of guardians with an undergraduate degree or higher education are likely to be sanctioned compared with 42.2% with an Associate of Arts (AA) or Technical (Tech) degree, and 36.9% with a high school diploma (HS) or equivalency (GED). Guardians with an undergraduate or higher education are 1.88 times more likely to be sanctioned compared with GED or HS graduates (p < 0.05). However, 83.3% of GED or HS graduates are likely to have more severe sanctions compared with 76.4% undergraduate or higher education, and 47.7% with an AA or Tech degree, respectively. Guardians with an AA or Tech degree are 0.28 times less likely to have more severe sanctions than guardians with an undergraduate degree or higher education (p < 0.01). The results are discussed with respect to guardian registration, licensing, certification and quality; licensing and regulation of other professions; the limitations of the study; and the need for further research.  相似文献

The aim of this study was to explore the role of character strengths and their associations to life satisfaction in older people. We were interested in studying several transitions that are specific for older people: aging, retirement, living alone, and being widowed. We examined the relationships of these demographic characteristics and living conditions with character strengths and studied their effects on the association of character strengths with life satisfaction. In a cross-sectional analysis, 15,598 older adults (aged 46–93 years) who had completed measures on character strengths, life satisfaction, and demographic characteristics and living conditions were selected from an existing database. Overall, analyses revealed positive associations of most character strengths with age, and higher scores in most character strengths for the employed (vs. the retired) and those living with a partner (vs. those living alone), while only few relationships with being widowed (vs. being married) were observed. Further, the contribution of character strengths to life satisfaction generally decreased slightly with age, but increased for certain character strengths, such as modesty or prudence. Also, stronger relationships between several character strengths and life satisfaction were found for retired people and those living alone, while being widowed did not affect these relationships. The results demonstrate how character strengths might contribute to the life satisfaction of older adults in various living conditions and thereby offer a starting point for strengths-based programs in later life.

Mice that are confined in a narrow cylinder readily bite inanimate targets. The following studies were conducted to determine the effects of tail shock on the target biting behavior of two strains of mice. During 20-min daily sessions, ten tail shocks were administered on a fixed-time 2-min schedule. One group of mice received a tone-conditioned stimulus (CS) which terminated with the onset of the shock, and a second group of mice did not. Target bites were collected in eight 15-sec bins over the 2-min trial and cumulated over the session. It was observed that tail shock was followed by an increase in target biting and that there was a comparatively high intershock interval biting rate. In addition, intershock interval biting was suppressed for the duration of the CS. These observations are discussed in terms of the utility of this paradigm for the psychopharmacological assessment of aggressive behavior.  相似文献

Recent research reported that general mental ability (GMA) predicted counterproductive work behavior (CWB), whereas some previous studies failed to find such a relationship. We tested occupational homogeneity of the sample and criterion measurement as two potential explanations for these inconsistencies. Study 1 replicated major design features of one previous study, which found no GMA–CWB relation in a heterogeneous sample, with occupationally homogeneous groups. Results confirmed previous null findings, indicating no effect of sample homogeneity. In Study 2, using a controlled laboratory setting, GMA was again unrelated to self‐reported CWB, but partially predicted observed CWB negatively. Combined findings suggest that GMA is consistently unrelated to CWB self‐reports but may predict objectively measured CWB independently of the likelihood of being caught.

This explorative study examines the effects of an internet-based cognitive-behavioural therapy for complicated grief on post-traumatic growth and optimism. The study is part of a larger randomized controlled trial described in Wagner, Knaevelsrud, and Maercker (2006). The patients were randomly assigned to either a treatment group (n = 26) or a waiting list control condition (n = 25). The internet-based intervention consisted of exposure to bereavement cues, cognitive reappraisal exercises, and a module on integration and restoration. A short form of the Post-traumatic Growth Inventory (PTGI), the Life Orientation Test-Revised (LOT-R), and measures of complicated grief and psychopathological outcomes were administered. Results indicate that post-traumatic growth increased in the treatment group. No treatment effect was found for optimism. These findings contribute to the growing literature on personal growth in psychotherapy.  相似文献

Evidence suggests that substantial proportions of adolescents, regardless of ethnicity or gender, are engaged in excessive weight control behaviors. Crago and Shisslak (2003), however, have noted that small samples and poorly validated instruments have limited the value of previous ethnic difference studies. Using the McKnight Risk Factor Survey, we compared Native American, White, and Hispanic adolescents. Native students were divided into groups with one (NA-mixed) or two (NA) Native American biological parents. Surveys were completed by 5th through 10th grade students. BMI z-scores were significantly higher for boys and girls in the NA group, and boys in this group were significantly more engaged in weight control behaviors, including purging. A higher percentage of Native and Hispanic girls preferred a larger body size. BMI was positively correlated with weight and shape concerns and with weight control behaviors, regardless of ethnicity or gender. Overweight among Native adolescents may put them at greater risk for eating problems than their White peers.  相似文献

The adaptation of vocabulary between communication partners, i.e. the lexical entrainment phenomenon, is well documented. This study investigates whether the phenomenon can also be found in computer‐mediated communication between experts and laypersons. The respondents, who are medical experts (n = 46), answered to fictitious patients' queries on health problems. Language technicality within patients' queries was manipulated. One version contained certain concepts in everyday language, the other in technical language. Do experts adapt the vocabulary in their replies to that in the inquiry? Detailed analyses provide evidence that experts not only use the inquiry vocabulary, but also adapt the content of their answers to the technicality of the inquiry. Surprisingly, though queries differ in the use of vocabulary experts attributed very similar prior knowledge to the fictitious patient while providing them with very different replies. The results are discussed with respect to the implications for health counselling and for theoretical assumptions about adaptation in net‐based discourse.

The aim of this study was to examine the potential moderating effect of age on the child-reported pain–social anxiety relationship in children and adolescents with sickle cell disease (SCD). Participants were children and adolescents (ages 8–17; 33 girls, 25 boys) diagnosed with SCD who completed measures of social anxiety and severity of usual pain. Caregivers provided demographic information, and mean hemoglobin levels were computed as a measure of objective disease severity. Ratings of more severe pain were associated with greater social anxiety, including fear of negative evaluation, for older children and adolescents only, revealing a moderating effect of age. Increased relevancy of peer relationships in adolescence, limited social contacts due to SCD complications, and misreading of social cues (e.g., maladaptive coping response to pain) may explain why older children and adolescents reported greater social anxiety in the presence of a stressor such as pain.  相似文献
