Additional inhibitors for the conversion of NO to NO2 in C3H6—NO—02 irradiated mixtures have been tested at 25°C. These mixtures initially contained 16 mTorr C3H6, 8 mTorr NO, 0.012 mTorr NO2, additive, and enough O2 to bring the total pressure to 100 Torr. The NO2 pressure was monitored photometrically. In the absence of additive, the NO2 pressure first increases with irradiation time reaching a maximum conversion at about 15 minutes. As the irradiation time increases beyond 15 min, the NO2 pressure drops. Before adding the inhibitors, runs were done with 10 Torr of CO added, and in these runs the conversion was speeded so that the maximum in NO2 pressure occurred at 10 min. This enhancement in conversion rate is considered to be diagnostic for the presence of HO radicals. Next 10-min irradiations were done with various amounts of hexafluorobenzene (C6F6), nitrobenzene (C6H5NO2), or naphtha lene (C10H8) added. The NO2 pressure was reduced to one-half its value in the absence of inhibitor with 270 mTorr C6F6’, 220 mTorr C6H5N02, or 4 mTorr C10Hg. The C10H8 is a very efficient inhibitor, but additions of up to 1 8.5 mTorr C10H8 did not reduce the N02 pressure to zero. Studies of the percent conversion of NO to NO2 vs. irradiation time were done with either 4.2 mTorr C10H8 or 40 mTorr 2,6-di-ferf-butyl-4-methylphenol (Ph) added. In the former case the peak conversion was delayed from 15 to 22 min, while in the latter case no delay occurred. However, with the Ph added, there appeared to be some reduction in the maximum value of percent conversion. 相似文献

Using meta‐analysis, we compare three attitudinal outcomes (i.e., job satisfaction, affective commitment, and turnover intent), three behavioral outcomes (i.e., interpersonal deviance, organizational deviance, and work performance), and four health‐related outcomes (i.e., general health, depression, emotional exhaustion, and physical well being) of workplace aggression from three different sources: Supervisors, co‐workers, and outsiders. Results from 66 samples show that supervisor aggression has the strongest adverse effects across the attitudinal and behavioral outcomes. Co‐worker aggression had stronger effects than outsider aggression on the attitudinal and behavioral outcomes, whereas there was no significant difference between supervisor, co‐worker, and outsider aggression for the majority of the health‐related outcomes. These results have implications for how workplace aggression is conceptualized and measured, and we propose new research questions that emphasize a multi‐foci approach.

A series of studies examined the effects of labelled meaning on affective response to housing scenes. Students at Ohio State University assessed their feelings towards imagined housing (public or private) and cities (Memphis, Houston and San Francisco). Expected differences in the affective quality were found. Responses to color photographs of specific housing scenes labelled as either private condominiums or public housing were obtained. Differences in scene-affect as a function of labelled meaning were found. Responses to housing scenes labelled as located in either Memphis, Houston or San Francisco revealed no differences in scene-affect as a function of label meaning. This latter finding was confirmed in a non-repeated measure examination. Differences in the fittingness, potency or relevance of the information provided may account for the pattern of findings. 相似文献

The effects of fathers' subjective work experiences on their children's behaviour have been largely neglected, despite increasing recognition accorded to the fathers' role in all aspects of child development. The present study redresses this issue by assessing whether (a) fathers' work experiences are related to children's behaviour, (b) the father-child relationship moderates the effects of fathers' work experiences on children's behaviour, and (c) specific child behaviours are associated with paternal work experiences. One hundred and forty two fathers (M age = 39.55 years) and their eldest child (M age = 9.2 years; 66 boys, 76 girls) participated. Moderated multiple regressions demonstrated that fathers' job satisfaction was related to specific child behaviours, viz. conduct problems and hyperactivity. More importantly, the father-child relationship moderated both these relationships: Where fathers were dissatisfied with their jobs, conduct problems and hyperactivity were significantly greater when the father-child relationship was of a higher quality. Implications for studying the effects of both mothers' and fathers' work experiences on their children's behaviour are drawn. 相似文献

We investigated the associations of the quantity and quality of part-time employment with the school performance (amount of class cutting, homework, and average grades) and personal functioning (self-esteem and time use) of high-school students. Two hypotheses were tested: (a) working long hours would be associated with detrimental effects, but (b) the quality of employment would moderate these effects, such that employment quantity would be associated with detrimental effects only for low quality jobs. Data from 563 high school students (n = 233 in part-time employment) provided support for the hypotheses. Conceptual, practical and policy ramifications of these findings are considered. 相似文献

Few studies on the interaction between work experiences and family functioning have focused on specific aspects of work and the family, nor have many studies identified links in the process whereby work affects the family. A four-stage model of how role ambiguity, role conflict, job insecurity and job satisfaction affect three aspects of marital functioning (sexual satisfaction, psychological aggression and general marital satisfaction) was tested. The two mediator variables linking work experiences and marital functioning were concentration difficulties and depression. In a sample of 190 employed married people the model fit the data. The three work stressors (ambiguity, conflict and job insecurity) affected all three aspects of marital functioning via concentration and depression, and the relationship between job satisfaction and marital functioning was mediated by depression. 相似文献

Whenever a short-term or local need in the exploitation of a scarce natural resource must be pitted against its long-term use or the needs of the larger community, the commons dilemma arises. The study of commons dilemmas originated in agricultural economies but has importance in all resource management areas. Psychologists have recently found it to be a useful paradigm in the study of decision-making behavior.This paper reviews the commons dilemma as it has been used in three areas of psychological research: games theory, animal and human territorial behavior, and behavior reinforcement. In the first area, results show how communication within groups operates in cooperation/competition situations. In the second, the effects of social and political ideologies are examined. In the third, the implications of the commons dilemma with regard to breaking out of social traps are discussed. Throughout, the relevance of this basic psychological research to rational resource management is made clear. An extensive bibliography of relevant original research is provided. 相似文献

Prenatal screening for sex chromosome aneuploidies (SCAs) is increasingly available through expanded non-invasive prenatal testing (NIPT). NIPT for SCAs raises complex ethical issues for clinical providers, prospective parents and future children. This paper discusses the ethical issues that arise around NIPT for SCAs and current guidelines and protocols for management. The first section outlines current practice and the limitations of NIPT for SCAs. It then outlines key guidelines before discussing the ethical issues raised by this use of NIPT. We conclude that while screening for SCAs should be made available for people seeking to use NIPT, its implementation requires careful consideration of what, when and how information is provided to users. 相似文献
