The study offers a development of the social technologies of “service” municipal administration. The consumers’ opinions should be taken into consideration when determining the nomenclature and standards of their provision, which include the quality parameters that the consumers consider important. In addition, “service” relations imply the assessment of consumer satisfaction with the services and the correction of services based on the results of the assessment. Since this interaction implies communication between the municipal administration body and service users, it is necessary to focus on communicative technologies that are capable of providing a full cycle of service development and improvement for young entrepreneurs. Communications should help determine the expectations associated with a service, raise awareness thereof, and involve young people in the decisions related to the provision of services.  相似文献

A central premise of the industry change literature is that firms change their strategic actions when an industry changes. Industry convergence (IC), the blending of boundaries between industries creating competition among firms that previously did not compete, is increasingly impacting many industries and is a salient case of industry change. Acquisitions are an important action shaping the course of IC because they trigger imitation and bandwagon effects further accelerating IC. This paper focuses on why and when learning from alliances reduces uncertainty resulting in acquisitions during IC: an ‘alliance experience transfer effect’. We demonstrate the utility of this mechanism for the substitution‐based form of IC that occurred between the telecommunications equipment and computer networking industries. Our key insight is that when the extent of IC is low there are significant transfer effects but, as the extent of IC increases, firms have access to an expanding volume and diversity of information sources that reduce uncertainty, thus weakening the transfer effect mechanism. We contribute to the alliance–acquisition relationship and learning literatures by demonstrating that the alliance experience transfer effect mechanism explains changes in firm strategic action (alliancing and acquiring) as the extent of IC changes. We also introduce a semi‐convergence perspective by directly measuring the extent of IC.  相似文献

Despite the prominence of attachment theory in international foster care literature and the importance of attachment relationships in successful foster care, attachment theory and practices do not feature prominently in South African foster care research. Against this backdrop, we interviewed twenty South African social workers' about their knowledge of attachment theory and their perceptions of attachment relationships in their own foster care work. Thematic analysis was used to analyse the interviews. We found that the social workers had limited knowledge of attachment theory and interventions; experienced most biological parents as unmotivated to improve their circumstances and attachment relationships with children; indicated that family reunifications were rare occurrences; reported foster parents were mostly kin; and experienced constraining contextual factors that hindered optimal consideration of attachment relationships in foster care supervision.  相似文献

Research has demonstrated that infants recognize emotional expressions of adults in the first half year of life. We extended this research to a new domain, infant perception of the expressions of other infants. In an intermodal matching procedure, 3.5‐ and 5‐month‐old infants heard a series of infant vocal expressions (positive and negative affect) along with side‐by‐side dynamic videos in which one infant conveyed positive facial affect and another infant conveyed negative facial affect. Results demonstrated that 5‐month‐olds matched the vocal expressions with the affectively congruent facial expressions, whereas 3.5‐month‐olds showed no evidence of matching. These findings indicate that by 5 months of age, infants detect, discriminate, and match the facial and vocal affective displays of other infants. Further, because the facial and vocal expressions were portrayed by different infants and shared no face–voice synchrony, temporal, or intensity patterning, matching was likely based on detection of a more general affective valence common to the face and voice.  相似文献

This article summarizes 10 presentations in a discussion group of the 2007 joint international symposium of the International Association for Educational and Vocational Guidance, Society for Vocational Psychology, and National Career Development Association held in Padua, Italy. This discussion group focused on interdisciplinary interactions in vocational guidance. The group engaged in dialogue to address the changing needs of world workers in the dynamic global economy by considering interdisciplinary research and practice implications. This article summarizes the major discussion topics and offers propositions for a way for the vocational guidance profession to move forward on these issues.  相似文献

Abstract

Control balance theory has been previously tested using measures of contingencies. This article builds upon these studies by using data collected from 460 undergraduate students to examine the role of constraints and sensation-seeking in the control balancing process. The findings provide partial support for control balance theory (i.e., that the control deficit and the control surplus both have significant links to predation). Examining the contingency effects showed that the influence of the control deficits and surpluses on deviance was conditioned by contingencies (i.e., high levels of sensation-seeking and low levels of constraint). The findings from this study suggest the need for further exploration of control balance theory, with the focus to shift to Tittle's 2004 revision of the theory.  相似文献
