This article assesses the appropriateness of lean supply and partnership relationship management policies as a means of invigorating industry, using the example of the UK pig and beef industry. The analysis assesses the extent to which it is operationally feasible, and with what commercial consequences, in UK pig and beef supply chains and markets. The analysis demonstrates that the lean and partnering approach is not always operationally feasible. Furthermore, when it is operationally feasible dominant players only – such as multiple retailers – appear to benefit commercially from its adoption. Given this, alternative policy options may be required in the future for such reinvigoration of industry. A framework to guide policy selection is provided. 相似文献

This study demonstrates that computational modeling and, in particular, agent‐based modeling (ABM) offers a viable compatriot to traditional experimental methodologies for criminology scholars. ABM can be used as a means to operationalize and test hypothetical mechanisms that offer a potential explanation for commonly observed criminological phenomena. This study tests whether the hypothesized mechanisms of environmental criminology are sufficient to produce several commonly observed characteristics of crime. We present an ABM of residential burglary, simulating a world inhabited by potential targets and offenders who behave according to the theoretical propositions of environmental criminology. A series of simulated experiments examining the impact of these mechanisms on patterns of offending are performed. The outputs of these simulations then are compared with several well‐established findings derived from empirical studies of residential burglary, including the spatial concentration of crime, repeat victimization, and the journey to crime curve. The results from this research demonstrate that the propositions of the routine activity approach, rational choice perspective, and crime pattern theory provide a viable generative explanation for several independent characteristics of crime. 相似文献

Although much literature has examined macrolevel employment contexts and crime rates and, at the individual level, employment and offending, few studies have examined systematically whether macrolevel employment contexts influence individual-level offending. At the same time, emerging literature on prisoner reentry increasingly underscores the potential importance of the social environment for impeding or facilitating successful transitions back into society. All three avenues of inquiry have emphasized the salience of race-specific and offense-specific effects. This study extends prior work on ecology and offending, employment and crime, and prisoner reentry by examining the race-specific effects of unemployment rates and manufacturing employment rates on violent, property, and drug recidivism. By analyzing data on male ex-prisoners released to 67 counties in Florida, we found, as hypothesized, that Black ex-prisoners released to areas with higher Black male unemployment rates have a greater likelihood of violent recidivism. No comparable effect was identified for White exprisoners. However, we found that White ex-prisoners, especially those without prior violent convictions, have a lower likelihood of violent recidivism when released to areas with higher White male manufacturing employment rates. We discuss the findings and their implications for theory, research, and policy. 相似文献

Studies of state fiscal and budgetary policies often use balanced budget requirements (BBRs) as explanatory variables. While current measures laid the crucial groundwork for a basic understanding of state BBRs, their lack of comprehensiveness threatens the validity of empirical work. Based on comprehensive legal research, this article offers a framework for analyzing state requirements: each state's BBRs form a coherent system for achieving budget balance through budget cycles; a fully developed BBR system offers a three‐line construct against imbalance; and the more complete, developed, and explicit a BBR system is, the more stringent it will be in achieving budgetary balance. 相似文献

Since 2001, the Conservative party has found itself in turbulent times. Yet the party has survived similarly difficult periods in the past, eventually recovering its strength and returning to power. Can it do so again? The problems for today's party exist along four key dimensions: leadership, policy, organisation and political circumstances. How grave are contemporary difficulties in each of these areas in comparison to past experience? To what extent is the party now in uncharted waters? Where are there valid historical parallels? The article offers a brief sketch of the lessons that the party needs to learn to recover its election winning formula ‐ an appetite for power and an impressive ability to adapt to changed circumstances. Today's problems are not insurmountable, but the party still has a huge mountain to climb if it is to return to government. 相似文献
