Early recognition of childhood mental-health problems can help minimise long-term negative outcomes. Recognition of mental-health problems, needed for referral and diagnostic evaluation, is largely dependent on health-care professionals’ (HCPs) judgement of symptoms presented by the child. This study aimed to establish whether HCPs recognition of mental-health problems varies as a function of three child-related factors (type of problem, number of symptoms, and demographic characteristics). In an online survey, HCPs (n = 431) evaluated a series of vignettes describing children with symptoms of mental-health problems. Vignettes varied by problem type (Attention-Deficit/Hyperactivity Disorder (ADHD), Generalised Anxiety Disorder (GAD), Autism Spectrum Disorder (ASD), Conduct Disorder (CD) and Major Depressive Disorder), number of symptoms presented (few and many), and child demographic characteristics (ethnicity, gender, age and socio-economic status (SES)). Results show that recognition of mental-health problems varies by problem type, with ADHD best recognised and GAD worst. Furthermore, recognition varies by the number of symptoms presented. Unexpectedly, a child’s gender, ethnicity and family SES did not influence likelihood of problem recognition. These results are the first to reveal differences in HCPs’ recognition of various common childhood mental-health problems. HCPs in practice should be advised about poor recognition of GAD, and superior recognition of ADHD, if recognition of all childhood mental-health problems is to be equal. 相似文献

Background and Objectives: Emerging adulthood is often marked with elevated symptoms of anxiety and depression. Hispanic emerging adults may face cultural stressors such as ethnic discrimination that further increase levels of anxiety and depression symptoms. The study aims were to examine if (a) self-esteem mediated effects of ethnic discrimination on symptoms of anxiety and depression, and (b) if gender moderated the indirect effects of discrimination. Design: The study design was cross-sectional self-report. Method: Two moderated mediation models were tested, with 1084 Hispanic emerging adults (ages 18–25) enrolled in institutions of post-secondary in the United States. Results: Results indicated that (a) higher ethnic discrimination was associated with higher anxiety symptoms (β?=?.05, p?=?.04), higher depression symptoms (β?=?.06, p?=?.02), and lower self-esteem (β?=??.30, p?.001); (b) self-esteem mediated the associations of ethnic discrimination with anxiety and depression symptoms; and (c) gender moderated the indirect effects of discrimination, whereby self-esteem was a stronger mediator among men than women. Each moderated mediation model explained 26% of variability in symptoms of anxiety and depression, respectively. Conclusions: Findings suggest that the mediating effects of self-esteem linking ethnic discrimination with symptoms of anxiety and depression vary between genders. 相似文献

This article deals with a modern disease of academic science that consists of an enormous increase in the number of scientific publications without a corresponding advance of knowledge. Findings are sliced as thin as salami and submitted to different journals to produce more papers. If we consider academic papers as a kind of scientific ‘currency’ that is backed by gold bullion in the central bank of ‘true’ science, then we are witnessing an article-inflation phenomenon, a scientometric bubble that is most harmful for science and promotes an unethical and antiscientific culture among researchers. The main problem behind the scenes is that the impact factor is used as a proxy for quality. Therefore, not only for convenience, but also based on ethical principles of scientific research, we adhere to the San Francisco Declaration on Research Assessment when it emphasizes “the need to eliminate the use of journal-based metrics in funding, appointment and promotion considerations; and the need to assess research on its own merits rather on the journal in which the research is published”. Our message is mainly addressed to the funding agencies and universities that award tenures or grants and manage research programmes, especially in developing countries. The message is also addressed to well-established scientists who have the power to change things when they participate in committees for grants and jobs. 相似文献

We present an associative recognition experiment comparing three samples of healthy people (young people, older people with high cognitive reserve [HCR], and older people with low cognitive reserve [LCR], with each sample consisting of 40 people), manipulating stimuli repetition during the study phase. The results show significant differences among the three samples in their overall performance. However, these differences are not due to a different use of familiarity, but rather due to a different way of using recollection: although there are no differences in the hit rates between the HRC and LRC samples, the LCR group makes significantly more recollective false alarms than the HCR group. Moreover, repetition provokes an increase in the recollective false alarms in the LCR group, but this does not occur in the group of young people or in the HCR group. These findings are explained in terms of recollection-based monitoring errors and seem to provide support for the cognitive reserve hypothesis. 相似文献

Inspired by Spence’s seminal work on transposition, we propose a synthetic approach to understanding the temporal control of operant behavior. The approach takes as primitives the temporal generalization gradients obtained in prototypical concurrent and retrospective timing tasks and then combines them to synthetize more complex temporal performances. The approach is instantiated by the learning-to-time (LeT) model. The article is divided into three parts. In the first part, we review the basic findings concerning the generalization gradients observed in fixed-interval schedules, the peak procedure, and the temporal generalization procedure and then describe how LeT explains them. In the second part, we use LeT to derive by gradient combination the typical performances observed in mixed fixed-interval schedules, the free-operant psychophysical procedure, the temporal bisection task, and the double temporal bisection task. We also show how the model plays the role of a useful null hypothesis to examine whether temporal control in the bisection task is relative or absolute. In the third part, we identify a set of issues that must be solved to advance our understanding of temporal control, including the shape of the generalization gradients outside the range of trained stimulus durations, the nature of temporal memories, the influence of context on temporal learning, whether temporal control can be inhibitory, and whether temporal control is also relational. These issues attest to the heuristic value of a Spencean approach to temporal control. 相似文献

This paper studies the economic effect of immigration on native working conditions, focusing on the impact of the inflow of immigrant labour on occupational mobility among native workers. Basing on a gender-segmented labour market, we propose an extension of the model presented by Peri and Sparber American Economic Journal: Applied Economics, 1(3), 135-169, (2009). The model controls for gender and time in order to check for potential differences in immigration effects associated with gender or immigrant length of residence. This research reveals the existence of such differences, by showing that female immigrant inflow has a greater positive short-term impact on occupational mobility among female unskilled native workers. In addition, the long-term study discloses a slight occupational assimilation of male immigrants towards employment patterns of male native workers and a permanent confinement of female immigrants in a few “niche jobs”. 相似文献

Choice confidence in the webrooming purchase process: The impact of online positive reviews and the motivation to touch

The webrooming purchase process (i.e. searching for information online and then buying the product offline) is the most extended cross‐channel shopping behaviour. With the aim of offering a better understanding of this behaviour, this research relies on information processing and uncertainty reduction theories to propose that consumers use the online information to make the offline purchase with a higher degree of confidence. We examine the effects of a previous online interaction with a product on the preferences and decision at the physical store, as well as on the outcomes of the experience. In this path to purchase, we analyse how positive online customer reviews, as a specific form of electronic word of mouth, help the consumer to improve their experience, given their great potential to reduce the consumer's uncertainty in a purchase situation. In addition, the role of the motivation to touch the product is examined. The results of two studies show that the combination of an online search and an offline purchase improves the consumers' purchase experience in pre‐choice variables (i.e. purchase intentions), choice and post‐choice variables (i.e. search‐process satisfaction and choice confidence). Moreover, reading a positive online customer review influences choice confidence, and all the variables considered in the research when it is received at the physical store. Finally, the results stress the importance of the motivation to touch when studying multichannel shopping behaviour, given its direct and moderating effects on the webrooming purchase process. Implications for theory and practice are discussed. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

Early math skills are determined by higher cognitive processes that are particularly important for acquiring and developing skills during a child's early education. Such processes could be a critical target for identifying students at risk for math learning difficulties. Few studies have considered the use of a structural equation method to rationalize these relations. Participating in this study were 207 preschool students ages 59 to 72 months, 108 boys and 99 girls. Performance with respect to early math skills, early literacy, general intelligence, working memory, and short‐term memory was assessed. A structural equation model explaining 64.3% of the variance in early math skills was applied. Early literacy exhibited the highest statistical significance (β = 0.443, p < 0.05), followed by intelligence (β = 0.286, p < 0.05), working memory (β = 0.220, p < 0.05), and short‐term memory (β = 0.213, p < 0.05). Correlations between the independent variables were also significant (p < 0.05). According to the results, cognitive variables should be included in remedial intervention programs. 相似文献
