Child care studies that have examined links between teachers' qualifications and children's outcomes often ignore teachers' and children's transitions between classrooms at a center throughout the day and only take into account head teacher qualifications. The objective of this investigation was to examine these traditional assumptions and to compare inferences made from these traditional models to methods accounting for transitions between classrooms and multiple teachers in a classroom. The study examined the receptive language, letter-word identification, and passage comprehension skills of 307 children enrolled in 49 community-based childcare centers serving primarily low-income families in Colorado. Results suggest that nearly one-third of children and over 80% of teachers moved daily between classrooms. Findings also reveal that failure to account for daily transitions between classrooms can affect interpretations of the relationship between teacher qualifications and child outcomes, with the model accounting for movement providing significant improvements in model fit and inference. 相似文献
Sleep deprivation reduces vigilance or arousal levels, affecting the efficiency of certain cognitive functions such as learning and memory. Here we assessed whether the differential outcomes procedure (DOP), a learning procedure that has proved useful to ameliorate episodic memory deficits, can also improve memory performance in sleep-deprived participants. Photographs were presented as sample faces. A probe face was then presented for recognition after either short or long delays. In the differential outcomes condition a unique reinforcer followed correct responses. In the non-differential outcomes condition reinforcers were provided in a random manner. The results indicated that the DOP prevented the recognition memory to decrement during the long delay in the control group, replicating previous findings. The sleep-deprived group showed DOP benefits mainly with the short delay, when working memory could be affected by low arousal. These findings confirm that the DOP can overcome impaired recognition memory due to sleep deprivation conditions. 相似文献
What is more important: to provide citizens with more money or with more autonomy for their subjective well-being? In the current meta-analysis, the authors examined national levels of well-being on the basis of lack of psychological health, anxiety, and stress measures. Data are available for 63 countries, with a total sample of 420,599 individuals. Using a 3-level variance-known model, the authors found that individualism was a consistently better predictor than wealth, after controlling for measurement, sample, and temporal variations. Despite some emerging nonlinear trends and interactions between wealth and individualism, the overall pattern strongly suggests that greater individualism is consistently associated with more well-being. Wealth may influence well-being only via its effect on individualism. Implications of the findings for well-being research and applications are outlined. 相似文献
Although laughter plays an essential part in emotional vocal communication, little is known about the acoustical correlates that encode different emotional dimensions. In this study we examined the acoustical structure of laughter sounds differing along four emotional dimensions: arousal, dominance, sender's valence, and receiver-directed valence. Correlation of 43 acoustic parameters with individual emotional dimensions revealed that each emotional dimension was associated with a number of vocal cues. Common patterns of cues were found with emotional expression in speech, supporting the hypothesis of a common underlying mechanism for the vocal expression of emotions. 相似文献
Advances in whole genome and whole exome sequencing (WGS/WES) technologies have led to increased availability in clinical settings. Currently, there are few guidelines relating to the process and content of informed consent for WGS/WES, nor to which results should be returned to families. To address this gap, we conducted focus groups to assess the views of professionals, parents, and adolescents for the future implementation of WES. The discussions assessed understanding of the risks and benefits of WES, preferences for the informed consent discussion, process for return of results, and the decision-making role of the pediatric patient. Professional focus group participants included bioethicists, physicians, laboratory directors, and genetic counselors. Parent focus groups included individuals with children who could be offered sequencing due to a potential genetic cause of the child’s condition. On-line discussion groups were conducted with adolescents aged 13–17 who had a possible genetic disorder. We identified discrepancies between professionals and patient groups regarding the process and content of informed consent, preference for return of results, and the role of the child in decision-making. Professional groups were concerned with the uncertainty regarding professional obligations, changing interpretation in genomic medicine, and practical concerns of returning results over time. Parent and adolescent groups focused on patient choice and personal utility of sequencing results. Each group expressed different views on the role of the child in decision-making and return of results. These discrepancies represent potential barriers to informed consent and a challenge for genetic counselors regarding the involvement of pediatric patients in decision-making and return of results discussions. 相似文献
This paper argues that potential cases of oppression, such as sex trafficking, can sometimes comprise autonomous choices by the trafficked individuals. This issue still divides radical from liberal feminists, with the former wanting to ‘rescue’ the ‘victims’ and the latter insisting that there might be good reasons for ‘hiding from the rescuers.’ This article presents new arguments for the liberal approach and raises two demands: first, help organizations should be run by affected women and be open-minded about whether or not the trafficked individuals should remain in the sex industry. Second, the career choices of trafficked individuals should be expanded by the introduction of an opportunity-extending right to asylum. 相似文献
In a couple of short papers, Donald Davidson holds that a creature cannot think unless it is the interpreter of the speech of another. At first blush, speaking a language is, therefore, a necessary condition for thought. His controversial claims has led many to regard him as a follower of the Cartesian tradition wherein languageless creatures are nothing but mindless machines. Against this widely shared interpretation, in this paper we put forward a more charitable interpretation of Davidson’s claims. According to our reading, Davidson never meant to argue that languageless creatures do not think. Instead, the only thing his arguments purport to show is that one will never be in a position to confirm that they do. This paper consists of a defense of the idea that Davidson is better seen as endorsing radical skepticism as to whether languageless creatures think.
As cognitive-behavior therapy (CBT) has proven to be an evidence-based intervention for many mental health problems, the requirement for training programs has increased. Although there is promising data on the skills outcomes of such programs, trainees’ affective/behavioral changes mechanisms and in their faulty thinking patterns during the personal development of such training are unknown. The aim of this study is to investigate which are the most common irrational/dysfunctional beliefs of trainees during a cognitive-behavioral intervention training and their maladaptive consequences, as well as the methods of restructuring that they prefer to change these beliefs into rational/functional ones and achieve more adaptive consequences. 94 participants in a cognitive-behavioral interventions training program filled out 340 ABC, forms related to negative events at work and in personal life, as part of the personal development component in the training program. The obtained qualitative data was coded by three trained ratters in accordance to the current cognitive model of CBT. Contingencies analysis showed that demandingness, awfulizing and global evaluation (GE) are most frequently associated with anxiety, while low frustration tolerance is associated with anger. Comfort, affiliation, achievement themes were most frequently associated with anxiety, while fairness was most frequently associated with anger. Pragmatic cognitive restructuring was the most frequently used by trainees. We found evidence that confirmed many of the theoretical predictions form the cognitive model of CBT in respect to the associations between irrational/dysfunctional cognitions and dysfunctional emotions as well as some particularities for this specific population. 相似文献
Digital technologies continue to change the ways women can access and consume sexual materials online, including pornography. Yet, limited research has considered the possibilities of digital technologies to enhance women’s access and consumption of online pornographic materials. In this paper, we use a cyberfeminist lens to examine women’s experiences consuming online sexually explicit materials, which most women defined as pornography including videos and images. In particular, we consider the ways women who identify as porn consumers can use digital technologies to enable and enhance their consumption of these pornographic materials. Drawing on qualitative, in-depth interviews with 11 women, our findings illustrate the ways women can use digital technologies to consume pornography online in ways that help them to fulfill their sexual needs, embrace and explore their sexual selves, connect in sexual relationships, and normalize their sexual desires. 相似文献
