All major world economies are exhibiting a shift from products to services in terms of relative share of GNP and employment. A well accepted explanation for this shift to services has been the lower productivity growth in services relative to manufacturing. A second trend visible in the United States and other advanced economies is that from material‐intensive to information‐intensive sectors with the latter growing relative to the former. There does not seem to be a generally accepted explanation for this shift; in fact, here it would appear that productivity in information‐intensive sectors is increasing. We construct a model of an economy with endogenous production and consumption decisions by utility maximizing individuals. We show that differential productivity changes can result in either relative growth or decline of a sector. A second factor affecting the direction of change is the degree to which consumption of sector outputs approaches satiation. When marginal utility of additional consumption drops sufficiently low, productivity increases can lead to declines in the relative size and share of, and employment in the sector. Concurrently, increases in productivity increase average wealth as expected, but income inequality can either increase or decrease. 相似文献
Objective: This study evaluated the mental health characteristics and beliefs of student service members/veterans (SSM/Vs) who have been exposed to another’s death by suicide.
Participants: A total of 39 SSM/Vs exposed to suicide and 32 SSM/Vs not exposed to suicide were sampled from a larger, epidemiological survey. An age- and gender-matched group of 39 civilian (C) students was drawn from a larger sample of individuals exposed to suicide.
Methods: Data were collected as part of an Internet-based, campus needs survey that occurred in Fall 2014. Participants were asked to complete measures about suicide-related behaviors, suicide prevention, help-seeking, and demographics.
Results: SSM/Vs exposed to suicide had more positive mental health/suicide prevention beliefs than SSM/Vs not exposed to suicide. Cs exposed to suicide were not significantly different from either group. Unique help-seeking patterns were also identified.
Conclusions: The current study identifies unique characteristics of SSM/Vs exposed to suicide that may inform prevention programming. 相似文献
Although face-to-face events starring film professionals have become increasingly popular, they have rarely been studied, especially from the perspective of production. Focusing on the phenomenon of Chinese movie roadshows, this study explores the motivations and techniques used to produce popular media events in the Chinese film industry. Based on expert interviews with 15 media practitioners, the results showed that roadshows are staged as ritualized events that are centered on the performance of a symbolic boundary between “inside” and “outside” the media. Film industry professionals embrace face-to-face communication with audiences and use such events to display sincerity, producing them as a seemingly “unmediated” peek behind the veil of an otherwise hidden world. Moreover, communication on social media is another form of ritualized practice. We conclude that, by thus mediating the “unmediated,” movie roadshows offer an insightful perspective on the machinery of media power in China. 相似文献
Firms pursuing technological alliances to gain competitive advantages have become a ubiquitous phenomenon in today’s business environment. This article examines which technological alliance portfolio configuration is better for focal firm performance using a portfolio rather than a dyadic perspective. To assess technological alliance portfolio effects on Korean pharmaceutical and biotechnology firms, we adopted three explanatory variables—number of alliances, number of partners, and spanning structural holes. The growth rate of revenue and the growth rate of profit are used as dependent variables. We identify two characteristics of technological alliance portfolios from the two-step generalized method of moments estimates. First, we find that between two firms with the same number of alliances, the firm with the larger number of partners would have a better performance. This result is unlike those in previous studies because it distinguishes between the number of alliances and number of partners based on the network theory. Second, we find that spanning structural holes affects firm performance rather like a double-edge sword—it positively affects the growth rate of profit but negatively affects the growth rate of revenue of firms. In short, spanning structural holes is simultaneously beneficial for firm profitability and unfavorable for firm growth. This result differs from those of earlier studies because it shows that a firm spanning structural holes among alliance partners produces either a positive or a negative effect, suggesting that a firm should vary its strategy depending on whether it prioritizes profitability or growth. 相似文献
Massey spresidential address correctly points to growing economic inequality as one of the pressing issues of our day, but his analysis gives short shrift to the political institutions that underlie the economic trends. We supplement his analysis with a review of some of those institutions. In particular we point out how politics mediates between computerized production and inequality, between the segregation of education and inequality, and (drawing directly from American Apartheid) between housing markets and residential segregation. 相似文献
This article explores the hypothesis that formal education of women results in increased child survival because of greater knowledge of the protective function of the major childhood immunizations. Education is also associated with greater awareness of proper immunization schedules. Irrespective of mother's formal education level, specific immunization knowledge is associated with an increased likelihood of using immunization. The Indonesian analysis is important as a model for preventive health campaigns among other populations with low education levels among women. 相似文献
This inquiry both builds on and extends exploration into gendered research through a focus on researcher vulnerability and its associated ethics. We discuss six critical vignettes across Western and Eastern contexts in which female researchers are “undone” and subsequently “redone” during their research endeavors. We draw upon Butler's work on gender and vulnerability, theorized as a subset of precarity. Attention is drawn to attempts to reframe, understand, and mobilize vulnerability differently, as a form of resistance, research activism, and emancipatory enactment. We propose agentic vulnerability as speaking to felt moments of vulnerability experienced in field research. We extend this contribution into a theorization of the researcher as activist, outlining practical applications of this concept. Ultimately, we seek to reposition agentic vulnerability in institutional research as a source of new ethics, research practices, and activism. 相似文献
