Contemporary agricultural practices account for a significant share of greenhouse gas emissions. Inspired by the emergent literature on institutional entrepreneurship, we seek to explore mechanisms that affect an actor’s propensity to act in ways that imply suggesting and promoting emission-reducing practice changes. As influences originating outside the organizational field are assumed to constitute such mechanisms, the paper explores their role through a case study of a project run by a public agency. Unlike extant theory, results show that the agency’s propensity to act is not necessarily enhanced by extra-field influences but that such influences also limit the scope for suggesting change that challenges existing industrial practices. 相似文献

Much recent attention in industrial practice has been centered on the question of which activities a manufacturing firm should complete for itself and for which it should rely on outside suppliers. This issue, generally labeled the “make‐buy” decision, has received substantial theoretical and empirical attention. In this paper, we broaden the scope of the make‐buy decision to include product design decisions, as well as production decisions. First, we examine independently the decisions of whether to internalize design and production, and then we consider how design and production organizational decisions are interdependent. The specific research questions we address are: (1) How can design and production sourcing decisions be described in richer terms than “make” and “buy”? (2) Do existing theories of vertical integration apply to product design activities as well as production decisions? (3) What is the relationship between the organization of design and the organization of production? (4) What organizational forms for design and production are seen in practice? After developing theoretical arguments and a conceptual framework, we explore these ideas empirically through an analysis of design and production sourcing decisions for bicycle frames in the U. S. mountain bicycle industry. 相似文献

In this article, we address the current debate of increasing work life flexibility in (West-) Germany. In order to shed some light on the contradiction between a widely accepted decrease in work life stability and empirical findings that do not confirm such a decline, we contrast “objective” evidence from occupational trajectories with “subjective” evidence on various dimensions of perceived continuity and discontinuity of job histories. We use the West German part of the German Life History Study for a survival analysis of occupational mobility for cohorts born between 1929 and 1971. Here, using a new concept, we distinguish between direct mobility and indirect mobility which is defined as an occupational change that happens after an employment interruption. In addition, we analyze a new German cross-sectional data set from 2005 on retrospective career perceptions. We employ multinomial regression models to understand whether younger individuals report more unwanted occupational mobility and employment interruptions than older individuals. Our findings indicate that direct occupational mobility has neither increased across cohorts nor has it surged upward for the most recent cohorts, but that there has been an increase in indirect occupational mobility. Furthermore, while there is no higher incidence of unwanted occupational mobility in younger age groups, we find mixed evidence regarding the increased occurrence of unwanted career interruptions in younger age groups. Finally, the desire to experience occupational and firm changes has grown for younger age groups. 相似文献

Parents' differentiation has been linked to negative psychological and behavioral outcomes in children, adolescents, and young adults. This line of research, however, has not been extended to families in later life. In this article, we use data from 671 mother‐child dyads in 275 families in the greater Boston area to explore whether mothers' differentiation among their children is related to psychological well‐being among offspring. We examined actual and perceived maternal differentiation in the domains of closeness, expectations for care, and conflict. We hypothesized that depressive symptoms would be higher when mothers differentiated among their children and when adult children perceived differentiation. Although the specific patterns varied somewhat by mothers' and children's reports, the findings indicated that, across all 3 domains, maternal differentiation was related to higher depression scores. 相似文献

We consider an infinite‐horizon exchange economy with incomplete markets and collateral constraints. As in the two‐period model of Geanakoplos and Zame (2002), households can default on their liabilities at any time, and financial securities are only traded if the promises associated with these securities are backed by collateral. We examine an economy with a single perishable consumption good, where the only collateral available consists of productive assets. In this model, competitive equilibria always exist and we show that, under the assumption that all exogenous variables follow a Markov chain, there also exist stationary equilibria. These equilibria can be characterized by a mapping from the exogenous shock and the current distribution of financial wealth to prices and portfolio choices. We develop an algorithm to approximate this mapping numerically and discuss ways to implement the algorithm in practice. A computational example demonstrates the performance of the algorithm and shows some quantitative features of equilibria in a model with collateral and default. 相似文献

Exploratory data structure comparisons: three new visual tools based on principal component analysis
Anne Helby Petersen Bo Markussen Karl Bang Christensen 《Journal of applied statistics》2021,48(9):1675
Datasets are sometimes divided into distinct subsets, e.g. due to multi-center sampling, or to variations in instruments, questionnaire item ordering or mode of administration, and the data analyst then needs to assess whether a joint analysis is meaningful. The Principal Component Analysis-based Data Structure Comparisons (PCADSC) tools are three new non-parametric, visual diagnostic tools for investigating differences in structure for two subsets of a dataset through covariance matrix comparisons by use of principal component analysis. The PCADCS tools are demonstrated in a data example using European Social Survey data on psychological well-being in three countries, Denmark, Sweden, and Bulgaria. The data structures are found to be different in Denmark and Bulgaria, and thus a comparison of for example mean psychological well-being scores is not meaningful. However, when comparing Denmark and Sweden, very similar data structures, and thus comparable concepts of well-being, are found. Therefore, inter-country comparisons are warranted for these countries. 相似文献

A rapidly expanding number of baby boomers provide care to aging parents. This study examines associations between caregiver status and outcomes related to awareness and anticipation of future long-term care (LTC) needs using 2007 Connecticut Long-Term Care Needs Assessment survey data. Baby boomers who were adult child caregivers (n = 353) versus baby boomers who were not (n = 1242) were more likely to anticipate some future LTC needs and to have considered certain financing strategies. Although baby boomer adult child caregivers more readily anticipate some future LTC needs, they are not taking specific actions. It is important to address the need for public education directed toward those who are currently (or have recently completed) caring for aging parents. 相似文献

This article focuses on the enduring significance of craft in the careers of Kent Royal Dockyard craftworkers and their sons and grandsons after deindustrialization. The closure of this naval shipbuilding and repair yard together with the subsequent move to post‐industrial employment did not end men's engagement with their craft practices. Instead, this developed into a ‘craft outlook’ defined by a motivation for performing actualizing labour that interwove paid and non‐paid work. Men's careers did not become individualized projects of self as collaborative intergenerational practices gave a long‐term narrative to their careers and lives. Therefore, three contributions are proposed to the literature on working‐class male careers and craft. First, an analytical framework is advanced that empirically distinguishes a ‘craft outlook’ from traditional manual trade employment. Second, a craft outlook reflected ‘whole life careers’ that were constructed from both paid and non‐paid work. Third, the concept of ‘human imprint’ is developed to recognize the generational affirmation produced by the transmission of craft practices. 相似文献

Although people with disabilities are frequently targeted as key beneficiaries of social protection, little is known on their access to existing programmes. This study uses mixed methods to explore participation in disability‐targeted and non‐targeted social protection programmes in Viet Nam, particularly in the district of Cam Le. In this district, social assistance and health insurance coverage among people with disabilities was 53 per cent and 96 per cent respectively. However, few accessed employment‐linked social insurance and other disability‐targeted benefits (e.g. vocational training, transportation discounts). Factors affecting access included the accessibility of the application process, disability assessment procedures, awareness and the perceived utility of programmes, and attitudes on disability and social protection. 相似文献
