A problem for many organizations is the low continuity of volunteers. Diverse theoretical models have been developed to explain sustained volunteerism, but most of these models have focused on the study of welfare volunteerism and not have verified whether their results could be generalized to other types of volunteerism. In this study, we propose a basic model to explain sustained volunteerism in any type of volunteerism. The aim of this study is to examine this basic model empirically in a sample of socio-assistential volunteers and in a sample of environmental volunteers. For this purpose, 290 volunteers completed a questionnaire and subsequently, two telephone follow-ups were carried out to determine whether the volunteers remained in the NGO one year later. The results show that the basic model offers an acceptable explanation of sustained volunteerism in the two types of volunteer samples studied, but it accounted for a low percentage of variance of the duration of service in both samples. Various relevant implications for the practical management of volunteerism in organizations are derived from theses findings.  相似文献

Some recent publications that explore the foundations of early language development are reviewed in this article. The review adopts the pivotal idea that infants' advancements are helped by the existence of different types of biases. The infant's discovery of the phonological properties of the language of the environment, as well as their learning of words, is assisted by different types of processing biases, ranging from perceptual to social factors.  相似文献

The term “dao” (道) has been playing the theoretically paradigmatic role in almost all East Asian philosophies, religions, and cultures. The meanings of the term “dao” in the Dao De Jing and other ancient East Asian texts have remained hermeneutically problematic up to this point in time. This article argues that one of the main causes of this hermeneutical problematic is the failure to establish a theoretically formal typology of the “dao.” It further suggests that a hermeneutically disciplined reading of the 76 uses of the term “dao” in the Dao De Jing accomplishes two important goals: (1) it demonstrates that a typological approach may enhance an understanding of the Laoian Dao, and (2) it provides some good data to begin reconstructing such a theoretically formal dao-typology.  相似文献

Evaluation point feedback was used to align confidence judgments with accurate/inaccurate responding to general knowledge questions. Rehearsal of item-answer pairs and three evaluation systems based on a scoring rule had different effects on confidence, accuracy and their relationship. Using standard calibration measures (Yates, J.F., (1990). Judgment and Decision Making. Englewood Cliffs, NJ: Prentice Hall) we found that a point system comprising of both rewarding (positive) and punishing (negative) consequences produced the best performance across levels of knowledge in comparison to all-rewarding and all-penalty rules.  相似文献

In order to clarify the role of the two broad components of psychopathy (interpersonal/affective and social deviance; R. D. Hare, 2003) in explaining maladaptive response perseveration in psychopaths, as well as the role of reflection after punished responses in this deficit, the authors administered a card perseveration task to 47 Spanish male inmates assessed using the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991). Hierarchical regressions showed that psychopaths' maladaptive perseveration (more cards played and less money earned) was uniquely predicted by the social deviance features of psychopathy (PCL-R Factor 2)--particularly by its impulsive and irresponsible lifestyle facet (PCL-R Facet 3)--and not by its interpersonal/affective features (PCL-R Factor 1). Moreover, perseveration was related to a lack of reflection both after punishment and after reward feedback. The authors' results, in conjunction with previous evidence indicating perseverative deficits in several impulse control disorders, suggest that response perseveration may not be specific to psychopathy but rather is associated more generally with the externalizing dimension of psychopathology.  相似文献

The lack of programs to train people in practical problem-solving is one of the challenges that professionals who attend people with mental deficiency must cope with. The main goal of this study is to assess the effects of a program designed to improve these skills, aimed at people with intellectual discapacity. The sample was made up of 66 subjects, aged between 17 and 36 years old. The program was based on the use of examples of fictitious characters who undergo situations that are similar to those of the subjects to whom the program is administered, and techniques to improve skills were generated from these situations. In order to achieve the goal, a classic pre- posttest design was used, with an experimental and a control group. The results show positive effects in most of the variables considered as a consequence of the administration of the program.  相似文献

Is it possible to learn to attend? The purpose of this article is to provide information about the development, administration, and contrast of an intervention program to improve selective and sustained attention in students from 5 to 19 years of age, all attending school, and with difficulties to learn the academic materials corresponding to their age. Two groups participated in the study: one with difficulties in selective attention and the other with difficulties in sustained attention. The group with selective attention difficulties was made up of 102 students, of whom 59 made up the experimental group and 43 the control group. The group of students with difficulties in sustained attention was made up of 106 students, of whom 58 participated as the experimental group and 48 as the control group. The results indicate that this kind of intervention (which combines visual therapy, cortical activation, and training with activity banks) is effective to improve attentional deficits, both at the level of selective attention and of sustained attention.  相似文献

Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity. In order to specify the contents of this positive state, the Complete State Model of Health (CSMH) considers mental health as a series of symptoms of hedonia and positive functioning, operationalized by measures of subjective, psychological, and social well-being. This model has empirically confirmed two new axioms: (a) rather than forming a single bipolar dimension, health and illness are correlated unipolar dimensions, and (b) the presence of mental health implies positive personal and social functioning. In the present article, we have taken the CSMH as the theoretical framework for the study of depression. Confirmatory factor analyses did not support the first axiom. In fact, the model that posits that measures of mental illness and health form a single bipolar dimension provided the best fit to the data.  相似文献

An experimental study of the influence of the recording interval and a graphic organizer on the processes of writing composition and on the final product is presented. We studied 326 participants, age 10 to 16 years old, by means of a nested design. Two groups were compared: one group was aided in the writing process with a graphic organizer and the other was not. Each group was subdivided into two further groups: one with a mean recording interval of 45 seconds and the other with approximately 90 seconds recording interval in a writing log. The results showed that the group aided by a graphic organizer obtained better results both in processes and writing product, and that the groups assessed with an average interval of 45 seconds obtained worse results. Implications for educational practice are discussed, and limitations and future perspectives are commented on.  相似文献
