初中学生心理健康状况及其影响因素

本研究对441名初中学生进行问卷调查,结果发现：1．有7．5％的初中学生存在明显的心理健康问题。2．初中学生心理健康存在性别与年级的差异。女生比男生,初三、初二学生比初一学生有更多的心理健康问题。3．日常生活压力是影响初中学生心理健康的重要因素。4．解决问题、求助两种应付方式对学生的心理健康有积极作用,而自责、幻想、忍耐、合理化等应付方式则会危害心理健康。     

Functional Status, Receipt of Help, and Perceived Health

We model the effects of disability, functional limitation, and receipt of help on perceived health. This analysis specifies a model with two dimensions of disability and three dimensions of functional limitation, including upper body disability, lower body disability, basic activities of daily living (ADLs), household ADLs, and advanced ADLs. The latent variables of receiving help are modeled for each of the ADLs as intervening between limitations and perceived health. The results show that instrumental social support in the form of receiving help for ADLs has no substantive independent effect on perceived health. In addition, receiving instrumental social support shows a pattern of task-specific responses to individual measures of need. Implications for both caregiver and care recipient are discussed.     

The relationship between feeding rate and patch choice.

Rats in a laboratory foraging simulation searched for sequential opportunities to feed in two patches that differed in the rate at which food pellets were delivered (controlled by fixed-interval schedules) and in the size of the pellets. The profitability of feeding in each patch was calculated in terms of time (grams per minute) and in terms of effort (grams per bar press). These values were the result of the imposed fixed interval, the size of the pellets, and the rate at which the rats pressed the bar in each condition. The rats ate more food and larger meals, but not more frequent meals, at the patch offering the higher rate of food consumption, calculated as grams per minute. The relative intake at any patch was a function of the relative rate of intake during meals at that patch compared to the other patch. Rats respond to explicit manipulations of feeding time in the same manner as they respond to manipulations of feeding effort.     

Animalizing women and feminizing (vegan) men: The psychological intersections of sexism,speciesism, meat,and masculinity

Images of sexualized women depicted as animals or alongside meat are routinely used in advertising in Western culture. Philosophers and feminist scholars have long theorized that such imagery reflects the lower status of both women and animals (vs. men) in society and argued that prejudiced attitudes towards women (i.e., sexism) and animals (i.e., speciesism) are interconnected, with meat-eating as a core symbol of masculinity. Addressing these key ideas from ecofeminist theory, we review the psychological evidence on the associations between sexism, speciesism, meat, and masculinity. Research on the animalistic dehumanization of women provides evidence that sexism and speciesism are psychologically entangled and rooted in desires for group-based dominance and inequality. Furthermore, research on the symbolic value of meat corroborates its masculine value expressing dominance and power, and suggests that men who abstain from meat consumption (e.g., vegans) are feminized and devalued, particularly by those higher in sexism. We conclude that a greater recognition of the interconnected nature of patriarchal gender relations and practices of animal exploitation, including meat-eating, can help in efforts to improve the status of both women and animals.     

Reciprocal Prospective Effects of Momentary Cognitions and Affect in Daily Life and Mood Reactivity Toward Daily Events in Remitted Recurrent Depression

Major depressive disorder is a recurrent condition. Potential risk factors for future episodes are maladaptive cognitions, such as rumination and unfavorable reactivity toward negative daily events. Positive thoughts and positive daily events, in contrast, could act as a buffer against mood deterioration. The aim of the present study is to (a) examine differences in daily affect and cognitions in remitted depressed patients with a history of recurrent episodes (rMDD) and healthy controls, (b) analyze reciprocal prospective effects of momentary cognitions and affect, and (c) investigate effects of daily events on affect and cognitions in both groups. A sample of N = 102 participants underwent an ecological momentary assessment (EMA) phase of 5 consecutive days, where rMDD patients (n = 51) and healthy controls (n = 51) indicated their momentary rumination, positive thoughts, affect, and the occurrence of daily events 10 times per day. Via multilevel lag models, we found higher rumination to predict a decrease of positive affect (PA) in the rMDD group, but no effect of rumination on subsequent negative affect (NA) in either group. Higher positive thoughts predicted an increase in PA and a decrease in NA, similarly strong in both groups. Regarding daily events, rMDD patients reported a stronger increase in NA and rumination following negative daily events compared to controls, whereas an observed subsequent decrease of PA and positive thoughts was not moderated by group. Following positive daily events, rMDD patients showed a stronger increase in PA and positive thoughts and a stronger decrease in NA and rumination than controls. For interventions targeting relapse prevention, our results indicate the implementation of strategies fostering the responsiveness to positive events and the up-regulation of positive affect.     

绿色消费的许可效应：绿色让我们更不道德？

绿色消费属于道德范畴,消费者在助推绿色社会发展中的作用日益受到重视。然而,绿色消费会降低指定性道德约束或增强禁止性道德选择,消费者会变得不再绿色甚至自私(如享乐、撒谎或偷窃),这便是绿色消费的许可效应。从时间维度上来说,绿色消费许可效应的产生包括启动效应-绿色消费-许可效应三个阶段。有关该效应的理论解释是道德自我调节。从根本上来说,化解该效应需要消费者养成绿色生活方式,它包括两个路径：一方面,从绿色行为到绿色自我,抽象化表征行为,将绿色行为与自我概念相连接,采用自下而上加工方式实现;另一方面,从绿色自我到绿色行为,基于价值观-行为一致性原则,会促进个体产生更多绿色消费以及节俭和利他,采用的是自上而下加工。文章最后指出未来一些研究方向。     

Does Object Height Affect the Dart Throwing Motion Angle during Seated Activities of Daily Living?

Abstract

Complex wrist motions are needed to complete various daily activities. Analyzing the multidimensional motion of the wrist is crucial for understanding our functional movement. Several studies have shown that numerous activities of daily livings (ADLs) are performed using an oblique plane of wrist motion from radial-extension to ulnar-flexion, named the Dart Throwing Motion (DTM) plane. To the best of our knowledge, the DTM plane angle performed during ADLs has not been compared between different heights (e.g. table, shoulder and head height), as is common when performing day-to-day tasks. In this study, we compared DTM plane angles when performing different ADLs at three different heights and examined the relationship between DTM plane angles and limb position. We found that height had a significant effect on the DTM plane angles - the mean DTM plane angle was greater at the lower level compared to the mid and higher levels. A significant effect of shoulder orientation on mean DTM plane angles was shown in the sagittal and coronal planes. Our findings support the importance of training daily tasks at different heights during rehabilitation following wrist injuries, in order to explore a large range of DTM angles, to accommodate needs of common ADLs.     

Daily Responsiveness,Expectations, and Self-disclosure: How the Average Levels and Within-person Variability of Three Relationship Components Mediate Personality–Relationship Transactions in Romantic Couples

The associations between couple members' personality and their relationship satisfaction can be conceptualized as reciprocal transactions. To better understand these transactions, we focused on both partners' interpersonal vulnerabilities (i.e. neuroticism, low self-esteem, and insecure attachment); daily emotional, cognitive, and behavioural relationship components (i.e. perceived responsiveness, positive expectations, and self-disclosure); and relationship satisfaction. Specifically, we examined whether the average levels and within-person variability of the relationship components mediated the transactions between interpersonal vulnerabilities and relationship satisfaction. Data came from 689 female–male couples aged 18 to 81 years who participated in three measurement occasions across 12 months, including a 14-day diary phase. We used mediated dyadic bivariate latent change score models to test the level–change and change–change transactions and mediations. The findings partly supported our hypotheses: Couple members with interpersonal vulnerabilities had lower average levels (but not higher within-person variability) of the relationship components, and less satisfied couple members had lower average levels and higher within-person variability of these components. The lower average levels but not the variability mediated between a lower level of relationship satisfaction and an increase in avoidant attachment. No other mediations were observed. We discuss the importance of studying daily relationship components for better understanding reciprocal transactions in couples. © 2020 European Association of Personality Psychology     

Thinking about the Needy, Justice, and International Organizations

This article has three main parts, Section 2 considers the nature and extent to which individuals who are well-off have a moral obligation to aid the worlds needy. Drawing on a pluralistic approach to morality, which includes consequentialist, virtue-based, and deontological elements, it is contended that most who are well-off should do much more than they do to aid the needy, and that they are open to serious moral criticism if they simply ignore the needy. Part one also focuses on the United States, and illustrates both how incredibly wealthy the U.S. is and some of the spending habits of its citizens; however, its considerations apply to the well-off generally. Section 3 considers whether justice provides reasons for helping the needy. Noting that justice in an extremely complex notion, it discusses numerous considerations relevant to justices scope and implications, including an extended Rawlsian conception of justice, an absolute conception, a comparative conception, the distinction between natural and social justice, and various elements of common-sense morality. Section 2 also distinguishes between agent-relative justice-based reasons, which are relevant to whether we act justly, and agent-neutral justice-based reasons, which are relevant to whether we have reasons of justicefor acting. Correspondingly, it argues that even if one can ignore the needy without acting unjustly, as philosophers like Robert Nozick and Jan Narveson contend, there may be powerful reasons of justicefor addressing their plight. Section 4 briefly address the responsibilities of international organizations like the World Bank, the International Monetary Fund (IMF), and World Trade Organization (WTO). Drawing on Section 2, it is suggested that in addition to standard reasons to act justlytowards needy members of the worlds community, there will be reasons of justicefor such organizations to aid the needy in both present, and future, generations. The article concludes by contending that the well-off in countries like the U.S. have reason to view international organizations like the World Bank, IMF, and WTO as their agents, and to seek to insure that they alleviate misfortunes amongst the worlds needy.
