A modification of the quartimax computation for factor rotation is described in which a hypothesized factor pattern is given to the machine along with the data. The machine uses the pattern to select the subset of variables to which it will attend when rotating in a given plane, in order to find an orthogonal solution which closely fits the hypothesis. The program also provides a measure of the goodness of this fit. The program can utilize pattern matrices that reflect only partial hypotheses as to the nature of the factors, as well as those that specify highly determined simple structure. 相似文献

In its first part, this paper shows why a recently made attempt to reduce the special theory of relativity to Newtonian kinematics is bound to fail. In the second part, we propose a differentiated notion of incommensurability which enables us to amend the contention that the special theory of relatively and Newtonian kinematics are incommensurable. 相似文献

We argue that Shogan's critique, as well as that of Fox, fails to engage with the central focus of our article, which was to characterize and evaluate different approaches to lesbian ethics and to propose an alternative to the more familiar approaches. 相似文献

In this target article the following hypotheses are discussed: (1) Colour is autonomous: a perceptuolinguistic and behavioural universal. (2) It is completely described by three independent attributes: hue, brightness, and saturation: (3) Phenomenologically and psychophysically there are four unique hues: red, green, blue, and yellow; (4) The unique hues are underpinned by two opponent psychophysical and/or neuronal channels: red/green, blue/yellow. The relevant literature is reviewed. We conclude: (i) Psychophysics and neurophysiology fail to set nontrivial constraints on colour categorization. (ii) Linguistic evidence provides no grounds for the universality of basic colour categories. (iii) Neither the opponent hues red/green, blue/yellow nor hue, brightness, and saturation are intrinsic to a universal concept of colour. (iv) Colour is not autonomous. 相似文献

In this survey study the question was asked how "life crisis," social conditions, and ratings of quality of life are related to psychological adjustment. The survey included 454 residents, and data were collected on five social conditions: income, education, age, marital status, and religious participation; four ratings of life quality: family, personal life, income, and overall quality of life; the number of recent changes in the lives of the respondents; and two indicators of psychological adjustment. These data were analyzed with multivariate analyses of variance and stepwise regression. Life crisis was associated directly with psychological adjustment. Social conditions and life quality ratings also had significant effects. People with high life-crisis scores reported more psychological distress, and poor social conditions appeared to further exacerbate their adjustment problems. Regardless of the magnitude of the crisis, quality of life ratings had sizable effects on reports of psychological adjustment. 相似文献

Ethical objections to the use of behaviour therapy in homosexuality are discussed. It is pointed out that these objections were often based on a limited view of the aims of the therapy. The need for evaluating such therapy, as it is currently used, is elaborated.Twenty subjects requesting behaviour therapy to reduce compulsive homosexual urges were randomly allocated, half to receive aversive therapy using electric shocks and half to receive covert sensitization. Both groups were studied for one year. There was no consistent trend for one therapy to be more effective than the other in reducing the strength of compulsive homosexual urges, and the response to both was similar to that reported in previous studies. It was considered that aversive therapies in homosexuality do not act by establishing a conditioned aversion, nor by altering the subjects' sexual orientation. They reduce aversive arousal produced by behaviour completion mechanisms when subjects attempt to refrain from homosexual behaviour in response to stimuli which have repeatedly provoked such behaviour in the past. 相似文献

Predicting the everyday life events of people is a relatively unexplored topic, although several major theoretical approaches deal with related issues. The dispositional approach would assign a causal role to personality, while the situational approach would locate causation in the person's environment. Variations on these two extreme themes invoke an interactionist interpretation. Beyond this, a genuinely transactional approach focuses on the enduring person-environment relationship established as people deal with major and everyday life events. This study investigated a wide range of predictors of daily positive, negative, and ill-health events over time in a sample of 206 older adults. Results showed that personality variables played only a minor role in predicting daily events, although an interaction between extraversion and social network size was significant. Background demographic variables and the major stressors of recent conjugal bereavement and physical disability played a role in daily event occurrences. Overall, the strongest degree of predictability of events came from the events themselves: The high degree of event stability over time indicated the value of a genuinely transactional model in understanding the occurrence of everyday events. 相似文献

Some effects of positive life events on community mental health 总被引:1,自引:0,他引:1
Measures of positive and negative events were derived from a life-event inventory to test the predictions of an equilibrium model and a positive mental health model of psychological well-being. These measures were related to indicators of individual and community well-being with data obtained through a household survey of 454 residents. Residents who reported more negative events also reported more psychological distress and less positive adjustment. Positive events were associated with reports of positive adjustment. An analysis of census tract scores on life events revealed that the relative absence of positive events in census tracts was associated with higher service utilization rates to the community mental health center serving those tracts. The number of negative events was unrelated to service rates for census tracts but was related to several demographic indicators of well-being. 相似文献
