Using data from the NICHD Study of Early Child Care and Youth Development (N = 1,198), this study examines the associations between education and parental strains and rewards among mothers of young children. Findings indicate that a college degree or more is related to less parenting anxiety, but more role captivity, and less new life meaning from parenting than lower levels of education. Differences by education are partly explained by variation in levels of progressive parenting values and work commitment, but remain significant. These patterns indicate that education provides greater resources that ease parental anxiety, but also leads to greater perceived demands of having a successful career, which contribute to more role captivity and less new life meaning from parenting.  相似文献

Staged performance involves the overt, scheduled identification and elevation of one or more people to perform, with a clearly demarcated distinction between them and the audience. It involves the agentive use of language, building on the foundation of existing social meanings. Staged performances tend to be linguistically stylized, pushing the limits of language creativity. They have the potential to trigger significant sociolinguistic effects, circulating novel forms and contributing to language change. The paradigms used in this theme issue for approaching language performance include Bakhtin's notion of Stylization, Bell's Audience and Referee Design, Silverstein's Indexicality, Agha's Enregisterment, and Bauman's construct of Discursive Culture. Themes that run through the articles include: a concept of identity that is part product, part process; the centrality of the audience; the reflexivity of staged performance; and the importance of non‐linguistic modalities such as music and appearance. The language analysis in this collection of papers concentrates mainly on phonological features of varieties of English, finding instances of selectivity, mis‐realization, overshoot and undershoot in their performances of a range of targeted dialects.  相似文献

This article concerns the use of language in both therapy and supervision, and how it contributes to the necessary risk‐taking that will be a part of therapists' and supervisors' repertoires. The focus will be on my own examples in both roles, and will refer to both successes and failures, while questioning the usefulness of either concept. Within a postmodern paradigm, and influenced by thinkers including Foucault and Bakhtin as well as systemic clinicians, I will examine the use of language (including in cross‐cultural settings where risks can sometimes be amplified) and of humour and self while exploring the meanings of identity. I contend that all relationships contain some element of risk and the ways in which we create a safe enough context, through the uses of language as well as nonlinguistic means, are the crucial elements in our endeavours as supervisors and therapists. I favour the idea that therapy is more of an art than a science and that this is most exemplified in the graceful use of language by which we strive to engage rather than alienate people. The article may be considered by some as being useful advice, and by others as a risk too far, such is the controversial nature of language, which highlights the importance of relationships and context.  相似文献

Religious leaders in Sub‐Saharan Africa do not just deal with the spiritual needs of members but are also heavily engaged in dealing with social problems and material needs. Although true elsewhere, the realities of limited state infrastructure and an increasingly diverse religious landscape make it crucial for religious entrepreneurs to deal with material problems if they hope to gain adherents. This article applies the concepts of problem solving and brokerage ( Burt, 2005 ; Knoke, 1990 ) to a case study of religious leaders in Balaka, a small town of rural Malawi. I argue that religious leaders solve problems in three major areas—material infrastructure, activities and organization, and healthcare—and that they are able to do so at least partly because of their connections to various overlapping secular and religious networks. I focus both on the provision of material resources and the facilitation of effervescent experiences in order to advance a fuller understanding of the experience of poverty and the ways leaders in poor communities work to solve problems.  相似文献

In this article, I investigate the capacity investment cost conditions where a multiproduct market leader may respond to a focus strategy entrant by using different strategies such as changing the product mix, production volumes, quality levels, and/or by investing in more capacity. The products offered in the market are quality differentiated and customers are heterogeneous in their willingness to pay for quality. The capacity investment costs of the two firms (i.e., the leader and the entrant) may also be different. The classical Stackelberg model predicts that an incumbent does not change its position in response to entry. However, when heterogeneous customer base, product differentiation, and capacity costs are taken into consideration, I find that the leader with a low capacity cost may choose to expand its product line and increase its production. The leader with low capacity cost may introduce a product that it was holding back when the entrant has to bear the high‐capacity cost and cannibalization threat is relatively small. Nevertheless, the extent of production volume strategies reduces as the capacity cost increases for the leader. I also find that when the leader has the power to set the industry standards by deciding the quality levels, as a response to a high‐quality focused entrant, the leader increases both levels of quality and production of the low‐quality product. Moreover, when the capacity investment cost is high for both the entrant and the leader, I find that market prices may increase with entry.  相似文献

Integrating the perspectives of transaction cost economics, the resource‐based view, and resource dependency theory, this study analyzes the institutional settings of enterprise resource planning (ERP) implementations in China. Specifically, it examines how bilateral transaction‐specific investments (TSIs) and relational governance mechanisms influence customer satisfaction with ERP implementations. The model is empirically tested using data from on‐site interviews with 208 ERP customers in China. The results demonstrate that the effects of vendors’ and customers’ TSIs on customer satisfaction are facilitated by multiple‐stage micromediational chains. The influence of TSIs on customer satisfaction is mediated by relational norms, and the impact of relational norms on customer satisfaction is bridged by perceived service quality and customer trust. Furthermore, the influence of vendors’ TSIs is stronger than the influence of customers’ TSIs. The findings contribute to business research and practice by providing valuable insights into how ERP vendors and customers should strategize TSIs to enhance relationship performance.  相似文献

In many supply chain relationships that continue over multiple periods, information about the hidden properties of the supply chain partners can be revealed throughout the course of the relationship. This article examines how the availability of such information affects the contracting scheme between a supplier and his manufacturer in a relationship that persists over several selling seasons. At the beginning of the first selling season, the manufacturer observes private information about the demand distribution, whereas the supplier who is less familiar with the market is endowed only with a prior belief about the market condition. When the supplier cannot observe the demand realization during the first selling period, she offers a contract that induces the manufacturer to reveal the market condition in the first selling season. However, the opportunity for the supplier to observe demand realization can result in the supplier offering the manufacturer a simple contract that does not induce the manufacturer to reveal his private information during the first selling season. In the latter case, the supplier observes the demand realization and designs the second period contract based on this information. We show that when the supplier chooses to offer such a contract, the manufacturer becomes worse‐off, and it has an ambiguous effect on the performance of the supply chain.  相似文献

Traditionally, IT security investment decisions are made in isolation. However, as firms that compete for customers in an industry are closely interlinked, a macro perspective is needed in analyzing these decisions. We utilize the notions of direct‐ and cross‐risk elasticity to describe the customer response to adverse IT security events in the firm and competitor, respectively, thus allowing us to analyze optimal security investment decisions. Examining both symmetric and asymmetric duopoly cases using a continuous‐time Markov chain (CTMC) model, we demonstrate that optimal IT security spending, expected firm profits and willingness of firms to cooperate on security improvements are highly dependent on the nature of customer response to adverse events. We also examine the investment problem when security attacks on different firms are correlated.  相似文献

In this study, we examined optimal pricing strategies for “pay‐per‐time,” “pay‐per‐volume,” and “pay‐per‐both‐time‐and‐volume” based leasing of data networks in a monopoly environment. Conventionally, network capacity distribution includes short‐/long‐term bandwidth and/or usage time leasing. When customers choose connection‐time–based pricing, their rational behavior is to fully utilize the bandwidth capacity within a fixed time period, which may cause the network to burst (or overload). Conversely, when customers choose volume‐based strategies their rational behavior is to send only the minimum bytes necessary (even for time‐fixed tasks for real time applications), causing the quality of the task to decrease, which in turn creates an opportunity cost for the provider. Choosing a pay‐per time and volume hybridized pricing scheme allows customers to take advantage of both pricing strategies while lessening the disadvantages of each, because consumers generally have both time‐ and size‐fixed tasks such as batch data transactions. One of the key contributions of this study is to show that pay‐per both time and volume pricing is a viable and often preferable alternative to the offerings based on only time or volume, and that judicious use of such a pricing policy is profitable to the network provider.  相似文献

The COVID‐19 pandemic has impacted the personal and professional lives of all of us and has laid the bases for a social and cultural change. This article is written as a reflection on the paradoxical effects of the ‘viral phenomenon.’ We wish to highlight the opportunities and changes that have arisen from the emergency situation, especially through the use of the online setting, both in the clinical work and training activities of systemic therapists. This article is not intended to be a panegyric on the merits of digital sessions, but an appraisal, also through clinical examples, of the contributions that technology may give to our practices. We do not consider technology as a substitute, but as an integration and enrichment of the therapist's and trainer's tools. This tough experience may be transformed into an opportunity for learning new techniques and practices in which the screen becomes a useful support.  相似文献
