This study examines macro and micro factors influencing the development of sense of community (Davidson & Cotter, 1980) in two different populations (immigrants and veterans) in new temporary neighborhoods in Israel. At the macrolevel, the major factors examined were population size, population density, number of dwelling units in the site, urbanity of the area, ethnic heterogeneity, and peripheriality of the region. Three kinds of variables were examined on the microlevel: (a) personal attitudes: evaluation of the dwelling unit and satisfaction with public services; (b) social networks; and (c) sociodemographic characteristics. Data were collected from 242 immigrants from the former USSR and from 60 Israeli veterans, residing in 5 different sites. Two different patterns of predictors of sense of community emerged in the two different samples. In the veteran sample, only one macrolevel variable entered the stepwise analysis equation: the number of dwelling units in the site. In the immigrant sample, three significant microlevel factors entered the equation: evaluation of the dwelling unit, external network, and age. The data thus suggest that the major determinant factors underlying sense of community vary for different groups of people. The paper is based on a study initiated and financed by the Ministry of Housing and Construction, the Unit of Social Policy, Israel.  相似文献

对时序信息加工的经典研究是采用新近性判断范型,结果发现其提取机制是以新近性为基础的逆向串行搜索过程。本研究采用新近性判断范型和早远性判断范型对时序信息的提取机制进行了深入的考察,结果表明:(l)提取时序信息既存在逆向串行搜索,又存在顺向串行搜索;(2)早远性判断和新近性判断任务对不同部分时序信息恢复的效应不同,其中早远性判断易化早远部分,新近性判断易化新近部分──表现为对相应部分辨别力的提高和正确反应潜伏期的缩短;(3)在不同的时序信息提取任务中,被试会根据具体条件进行反转反应。  相似文献

The contributions to this Special Issue illustrate research on several important types of environmental units, including psychiatric and substance abuse treatment programs, neighborhood block groups, and entire communities. They also exemplify alternative methodologies, such as assessing environments by relying on participants' appraisals, external observers' ratings, historical archives, and direct observation. I draw on these contributions and some of my own work to discuss four recurrent issues: (a) how to conceptualize environmental domains and dimensions; (b) how to understand environmental dynamics, that is, the interplay of environmental factors both within one setting and across settings; (c) how to comprehend the processes that link environmental factors to outcomes, especially with respect to the power and evanescence of environmental influence; and (d) how to use information about environments to monitor and improve them. Increased knowledge in these four areas is essential to help fulfill a major aim of community psychology: to understand social processes and improve intervention program outcomes.  相似文献

In this study it was determined whether (a) classification as opposed to absence of classification has an effect on the quality of clinical hypotheses (b) the DSM-III-R and the CBCL have a different effect on the quality of clinical hypotheses, and (c) the potential difference between the DSM-III-R and the CBCL is moderated by the different number of syndromes identified by these systems. To investigate these questions, an experiment was conducted in which 86 clinicians generated hypotheses for six cases. The clinicians were divided into a DSM-III-R, a CBCL, and a control group. Of the six cases, two were classified by both classification systems as one syndrome, two were classified as one syndrome by the DSM-III-R but as two syndromes by the CBCL, and two were classified as two syndromes by the DSM-III-R but as one syndrome by the CBCL. The quality of the hypotheses was determined by means of four dependent variables selected from an overview of qualitative criteria: explanatory value, redundancy, possibility of operationalization, and specificity. No differences between the CBCL and the control groups were found. The DSM group performed better than the control group regarding explanatory value and redundancy. The DSM-III-R group also scored better than the CBCL group regarding explanatory value, particularly when the number of identified syndromes was two for the CBCL and one for the DSM-III-R.  相似文献

A review of the literature resulted in 21 published studies that reported mean MMPI profile patterns for PTSD patients. Of these, six (29%) reported that the mean 8-2 profile pattern significantly differentiated PTSD patients from non-PTSD patients. The majority of studies found additional PTSD profile patterns reflecting nearly all of the MMPI clinical scales. The data indicate some common group profile patterns for inpatient veterans, prisoner's of war, and inpatient veteran substance abusers. The results also support the hypothesis that there is a continuum from inpatient to outpatient and veteran to civilian populations that corresponds with both symptom and stressor severity. It is concluded that although there is some typicality in similar populations, clinicians should expect heterogeneous MMPI profiles from PTSD patients representing a diversity of clinical symptoms and styles.  相似文献

A. F. Losev, one of the most important Russian philosophers and historians of ancient aesthetics and culture in the 20th century, develops in his ‘Dialectics of the Myth’ (Dialektika mifa), 1930, a personalistic ontology by using elements of neoplatonic philosophy and Orthodox Christian belief. According to Losev reality in all its different expressions and ontological strata must be understood as “mythical”, i.e. as “living mutual exchange of subject and object”. The subjective and personal aspect of reality is not grounded in man’s epistemic relation to it alone; reality in itself has to be characterized as personal and subjective. The main philosophical opponent is Descartes, the founder of “modern rationalism and mechanism”.

Premise acceptability is conceptually connected to presumption. To say that a premise is acceptable just when there is a presumption in its favor is to give a first approximation to this connection. A number of popular principles of presumption suggest that whether there is a presumption for a premise, belief, or claim depends on the sources which vouch for it. Sources consist of internal belief-generating mechanisms and external testimony. Alvin Plantinga's notion of warrant lays down four conditions upon a source for the belief which it generates to be warranted. We argue that there is a presumption for a premise, belief, or claim if and only if there is a presumption of warrant for that premise,belief or claim. This amounts to the thesis that there is a presumption for a belief from a challenger's point of view if and only if there is a presumption from that person's point of view that her cognitive faculties which have generated the belief have been functioning properly, in an appropriate cognitive environment, in accord with a segment of her design plan aimed at the truth, and that these faculties are reliable. In light of our argument for this thesis, we may legitimately claim that one way to determine that there is a presumption for a belief is to determine that there is a presumption of warrant for that belief, and thus that in determining whether there is a presumption for a belief or premise, we may consider the source.  相似文献

In teaching discriminations to persons with retardation, we often presume we will improve acquisition and generalization if we use multiple examples of boththe correct and incorrect stimuli. Two experiments were conducted to test this hypothesis. In the first experiment, 7 persons with moderate retardation learned to discriminate between functional words under two conditions. In one condition, Multiple Example of S- Only,1 example of the correct stimulus (S+) and 10 examples of the incorrect stimulus (S-) were used during acquisition. In the other condition, Multiple Examples of S+ and S-,10 examples of the S+ and 10 examples of the S- were used. Results showed that the condition which presented only a single example of S+ was superior 16 times and inferior 4 times during acquisition, generalization, and maintenance. A second experiment was conducted to (a) replicate the methodology and procedures in Experiment 1 with different participants, (b) determine whether the results were replicable, and (c) obtain efficiency data. Results replicated the findings of the first experiment. The condition which presented only a single example of S+ was superior on measures of (a) trials to criterion, (b) percent correct during acquisition, and (c) minutes to criterion. On measures of generalization, the two conditions were relatively equal. Thus, the condition which presented only a single example of the correct stimulus was more efficient and was just as effective in generalization as the condition which presented multiple examples of both the S+ and S-. These surprising results were discussed in terms of stimulus control, why students performed just as well during generalization when only one example of the S+ was used, why acquisition was also poorer for this condition, and how future studies might address these points.  相似文献
