Farm persistence and adaptation at the rural–urban interface: Succession and farm adjustment

Despite assumptions that agriculture will automatically go into a mode of decline at the Rural Urban Interface (RUI), official statistics suggest that agriculture as a whole remains a strong (and in some cases a growing) industry in many U.S. RUI counties. RUI scholars have acknowledged internal family dynamics can significantly influence farm persistence and adaptation strategies, however, few studies have sought to document the specific role succession has on farm structure at the RUI. Building off rural geography models of farm organization at the RUI and succession research embedded in rural studies we analyze interviews from 33 U.S. farm families to 1) explore the relationship between farm adaptation and succession at the RUI, and 2) examine how succession is related to the different types of enterprises found at the RUI (direct marketers vs. commodity producers) and the types of growth strategies these farm families implement. We find that families who can not identify an heir either disinvest or enter a static management mode. Among farm families who can identify an heir we identify a variety of horizontal and vertical growth strategies (expanding, intensifying, and entrepreneurial stacking) designed to achieve farm reproduction goals. We discuss the theoretical and policy related implications of this research.     

The Effect of Cocaine Prices on Crime

The relationship between cocaine prices and crime has critical implications for U.S. drug policy, but is theoretically indeterminate because cocaine price changes affect crime through changes in both cocaine consumption and expenditures. This paper investigates this relationship in annual data from 1981–95 on 29 large U.S. cities, accounting for simultaneity by using two-stage least squares with measures of wholesale supply factors and retail enforcement intensity as instruments for cocaine prices. Controlling for prices of other drugs, deterrence, socioeconomic factors, and city and year-specific effects, a strong negative relationship exists between cocaine prices and six of seven FBI index crimes.     

The Core Competency Movement in Marriage and Family Therapy: Key Considerations From Other Disciplines

There is a growing movement to define competency within the field of marriage and family therapy (MFT), particularly with respect to the training of practitioners and the evaluation of clinical practice. Efforts to define competency, however, transcend the practice of MFT and much can be learned from the experiences of other disciplines. Professions such as education, law, and medicine have made strides toward addressing the complex issue of competency standards in their respective fields. This article describes some ways in which the issue of competency has been approached in other professions, as well as some common dilemmas posed by adopting a competency-based orientation, to shed light on the process of defining competency in MFT. Moreover, this article identifies some of the more useful conceptualizations, modes of pedagogy, and evaluative practices found in other professions.     

A Mixed Methods Study of Recently Homeless Youth Efforts to Sustain Housing and Stability

This study examined the process of establishing post homeless lives among 51 recently homeless youth in two major urban centers in Canada. A mixed methods strategy was employed to characterize this process. Quantitatively, a range of mental health, community integration, and quality of life measures were employed four times over the course of 1 year to describe how these indicators of wellbeing shifted in this period. It was found that over the course of 1 year gains were not made in community integration, quality of life and mental health were highly variable, and hope declined significantly. Further, it was found that youth in supported housing arrangements experienced better mental health and community integration. Qualitatively, we identified three major stages in the process of exiting homelessness. These stages included a period of substantial fluctuation and instability, a period of gaining a basic level of stability but being demoralized due to difficulties making progress with life goals, and a period of making some gains with life goals which cultivated a sense of hope. Progress across these stages, which took place in a timeframe considerably longer than 1 year, was characterized by a range of setbacks, individual and systemic challenges, and trauma which were addressed through a persistent effort facilitated by youth resilience and key supports.     

Binary Time Series Modeling with Application to Adhesion Frequency Experiments

Repeated adhesion frequency assay is the only published method for measuring the kinetic rates of cell adhesion. Cell adhesion plays an important role in many physiological and pathological processes. Traditional analysis of adhesion frequency experiments assumes that the adhesion test cycles are independent Bernoulli trials. This assumption can often be violated in practice. Motivated by the analysis of repeated adhesion tests, a binary time series model incorporating random effects is developed in this paper. A goodness-of-fit statistic is introduced to assess the adequacy of distribution assumptions on the dependent binary data with random effects. The asymptotic distribution of the goodness-of-fit statistic is derived and its finite-sample performance is examined via a simulation study. Application of the proposed methodology to real data from a T-cell experiment reveals some interesting information, including the dependency between repeated adhesion tests.     

3PL整合：关系因素与运营结果

从规范性关系承诺和工具性关系承诺两个维度探讨影响信息共享和流程协调的关系因素,研究两种整合方式对3PL用户绩效的作用以及不同绩效之间的关系。基于361家企业数据,采用结构方程模型方法,建立关系承诺－3PL整合－绩效的模型,验证三者之间的关系。研究结果表明,规范性关系承诺正向影响信息共享和流程协调,而工具性关系承诺对二者没有显著影响;信息共享促进3PL用户的配送绩效,流程协调对3PL用户的配送绩效和弹性绩效均有促进作用;信息共享和流程协调不能直接影响3PL用户的财务绩效,但通过配送绩效和弹性绩效间接影响财务绩效。研究结果对中国企业的3 PL管理实践具有指导意义。     

Performance Metric Portfolios: A Framework and Empirical Analysis

The widespread adoption of supply chain management principles suggests that managers recognize the importance of evaluating operational decisions holistically. However, it is often difficult to link specific operational practices to strategic level outcomes and in turn to corporate financial results. This presents problems for both managers and academic researchers attempting to justify the often high cost of operational improvement initiatives in terms of objective accounting metrics. This study provides evidence that it is possible to demonstrate linkages between carefully chosen portfolios of tactical, strategic, and financial metrics. Survey data from 118 manufacturers are used to evaluate hypotheses linking multilevel metrics of performance across three well‐established strategic foci. We present portfolios of metrics drawn from the literature and from the Supply Chain Counciľs supply‐chain operations reference model and related design and customer chain models. Our analysis suggests that metric portfolios in which tactical metrics are designed to match strategic‐level metrics, based on alignment with a specific strategic focus, provide clearer mechanisms for understanding performance linkages.
