我们大多数人都认同创新是成长的关键途径。问题是如何创新?许多企业依靠突发机遇。也就是说,他们指望某个人提出产品或服务方面的点子,然后从中获利。然而有些时候,企业必须发掘比以往更多的创意,并先于竞争对手将创意化为切实可行的产品与服务。此时,企业便不能再依靠机缘巧合了。我们需要可持续、可重复的创新方法。 相似文献

Using Difference Scores to Inform Therapy Practice: Differences in Perceptions of Attachment Behaviors between Partners in a Clinical Sample 下载免费PDF全文
Using clinically relevant research methodology, this study focuses on differences (cross‐partner difference scores) in perceptions of attachment behaviors (emotional accessibility, responsiveness, and engagement) between partners in couples therapy. In general, findings suggest that higher levels of self‐enhancement attachment behaviors (participant perceives self as demonstrating more attachment behaviors than the partner's ratings of the participant) are associated with lower relationship satisfaction and greater relationship instability. The association between attachment behavior difference scores and measures of relationship health is mediated through partner perceived positive communication. These results suggest that differences in perceptions between partners’ level of attachment behaviors are an important clinical construct for therapy. As such, clinical recommendations for addressing self‐enhancing attachment behaviors, and the mediating role of positive communication, are discussed with recommendations for researchers. 相似文献

When immigrants enter the US they typically access a marriage market with a larger supply of educated spouses compared to the marriage market in their home countries. Absent any selectivity bias, this access should increase the likelihood that migrants ‘marry-up’ in terms of education. We combine survey data on British and German immigrants in the US with data on natives in Britain and Germany to estimate the causal effect of migration on educational mobility through cross-national marriage. To control for selective mating, we instrument educational attainment using government spending on education in the years each person was of school-age. To control for selective migration, we instrument the migration decision using inflows of immigrants to the US during puberty and early adulthood. We find strong selectivity effects that work against the positive prospects of the US marriage market. All migrants give up spousal education in exchange for US entry and assimilation. Migrant men also give up spousal education because they cannot compete with native men as bread-earners. Migrant women have some advantage in the US marriage market, as they can compete with native women in home production. 相似文献

A global count of the extreme poor in 2012: data issues,methodology and initial results 总被引:1,自引:0,他引:1

The 2014 release of a new set of purchasing power parity (PPP) conversion factors (PPPs) for 2011 has prompted a revision of the World Bank’s international poverty line. In revising the line, we have sought to minimize changes to the real purchasing power of the earlier $1.25 line (in 2005 PPPs), so as to preserve the integrity of the goalposts for international targets such as the Sustainable Development Goals (SDGs) and the World Bank’s twin goals – which were set with respect to that line. In particular, the new line was obtained by inflating the same fifteen national poverty lines – originally used by Ravallion et al. (World Bank Econ. Rev. 23(2): 163–184 2009) to construct the $1.25 line – to 2011 prices in local currency units, and then converting them to US dollars using 2011 PPP conversion factors. With a small approximation, this procedure yields a new international poverty line of $1.90 per person per day. In combination with other changes described in the paper, this revision leads to relatively small changes in global poverty incidence for 2011: from 14.5 % using the old method to 14.1 % using the new method. In 2012, the new reference year for the global count, we find 12.7 % of the world’s population, or 897 million people, are living in extreme poverty. There are changes in the regional composition of poverty, but they are also relatively small. This paper documents methodological decisions taken in the process of updating both the poverty line and the consumption and income distributions at the country level, including issues of inter-temporal and spatial price adjustments. It also describes various caveats and limitations of the approach taken. 相似文献

While recent studies have suggested that the timing of sexual initiation within a couple's romantic relationship has important associations with later relationship success, few studies have examined how such timing is associated with relationship quality among unmarried couples. Using a sample of 10,932 individuals in unmarried, romantic relationships, we examined how four sexual-timing patterns (i.e., having sex prior to dating, initiating sex on the first date or shortly after, having sex after a few weeks of dating, and sexual abstinence) were associated with relationship satisfaction, stability, and communication in dating relationships. Results suggested that waiting to initiate sexual intimacy in unmarried relationships was generally associated with positive outcomes. This effect was strongly moderated by relationship length, with individuals who reported early sexual initiation reporting increasingly lower outcomes in relationships of longer than two years. 相似文献

Whether government‐based forms of food assistance such as the Supplemental Nutrition Assistance Program (SNAP), communal efforts including food pantries, aid from friends and family, or alternative means such as gardening are the appropriate means to reduce the prevalence of household food insecurity is a continuous source of policy contention. To inform this debate, we examine the relative importance of these forms of food assistance and acquisition to a sample of U.S. older adults from the 2010 Brazos Valley Health Assessment of central Texas households that have been stratified by income eligibility for SNAP, low‐income SNAP ineligibility, and above low income status. To identify how membership in these socioeconomic groups constrains household capacity to acquire sufficient food to maintain an adequate and healthy diet, we explore the varied associations of assets received from government; communal and intimate social networks; and alternative food sources such as gardening, hunting, and fishing with household food security across socioeconomic status, while examining the importance of place of residence on the use of capital assets. SNAP participation was the only specific capital asset associated with all levels of food insecurity for both SNAP‐eligible and ineligible low‐income groups, thus emphasizing the continued importance of food assistance among poverty‐level older adults. 相似文献

In the 21st Century global public relations professional community, the need for a postmodern reformation is compellingly evident. Most theorizing begins with basic assumptions about the three main social actors for which public relations has been practiced: (1) corporations, (2) nongovernmental and civil society organizations (NGOs and CSOs), and (3) governments. Questions about society itself are rarely examined, but when they do come up, scholars and practitioners tend to assume generally accepted values and mores. Neglected has been a robust criticism of the concepts upon which such paradigms have been built. 相似文献

Say Yes First--To Rural Youth and Family Alcohol/Drug Prevention (SYF) was a 5-year, federally-funded U.S.D.H.H.S. Center for Substance Abuse Prevention (CSAP) project that involved 859 children in the class of the year 2000. The children in four rural school districts were followed from Grade 4 to Grade 8 from 1991 to 1996. Initial results in a previous publication showed significant lower drug usage in this cohort than comparison students. A follow-up of 120 SYF participants and 136 comparison students in high schools using the National Youth Survey (Follow Up Questionnaire) indicated lower usage of alcohol, tobacco and other drugs for the program students and lower lifetime prevalence of marijuana use for program vs. comparison students. SYF students had higher course grades, lower school absenteeism, more positive attitudes toward school, less trouble in school and less negative self-appraisal. Program students also reported greater participation in sports, more family communication and fewer disagreements or arguments with their parents. 相似文献
