This paper seeks to show, by an arithmetical example, that increased productivity through mechanization can lead to results which make a country worse off. The example shows that the installation of an imported labour‐saving machine will appear not only to have increased productivity, but also to have raised the proportion of investment in G.N.P. and the proportion of capital goods in total imports. All the indications, therefore, lead one to expect a rise in welfare. What the figures hide is that people for whom there are no other opportunities of earning a living have lost their jobs and that consumer goods imports have fallen because both the unemployed and others can no longer afford them. It is not even as if these welfare losses were temporary and bearable because they might ultimately lead to faster economic growth. The example shows that there is no reason to expect that to happen. The paper does not, of course, say that mechanization is invariably harmful—that would be ludicrous—but seeks merely to warn against mechanization in particular circumstances, which arise, however, only too often in underdeveloped countries. 相似文献

In the field of forensic DNA typing, the analysis of Short Tandem Repeats (STRs) can fail in cases of degraded DNA. The typing of coding region Single Nucleotide Polymorphisms (SNPs) of the mitochondrial genome provides an approach to acquire additional information. In the examined case of aggravated theft, both suspects could be excluded of having left the analyzed hair on the crime scene by SNP typing. This conclusion was not possible subsequent to STR typing. SNP typing of the trace on the torch light left on the crime scene increased the likelihood for suspect no. 2 to be the origin of this trace. This finding was already indicated by STR analysis. Suspect no. 1 was excluded for being the origin of this trace by SNP typing which was also indicated by STR analysis. A limiting factor for the analysis of SNPs is the maternal inheritance of mitochondrial DNA. Individualisation is not possible. In conclusion, it can be said that in the case of traces which cause problems with conventional STR typing the supplementary analysis of coding region SNPs from the mitochondrial genome is very reasonable and greatly contributes to the refinement of analysis methods in the field of forensic genetics. 相似文献

In Gottfredson and Hirschi's self‐control theory, introduced in 1990, they contend that self‐control is a unidimensional construct that develops early in childhood and remains stable throughout the life span. According to findings reported in recent research, however, these arguments are now being challenged, with scholars pointing to ways in which self‐control may be multidimensional in nature and may change beyond the period of alleged stabilization. In this study, we draw on Steinberg's dual systems model, introduced in 2008, to consider this issue further. We examine that model's two key elements of low self‐control—risk‐seeking and impulsivity—to determine whether they are empirically distinguishable from one another and have differing developmental trajectories from childhood to early adulthood. We also consider the consequences of changes in risk‐seeking and impulsivity for within‐individual changes in crime. We examine these issues with data from the National Longitudinal Survey of Youth 1979 (NLSY79) for individuals from 10 to 30 years old. The results of our analyses show support for a multidimensional and dynamic conception of self‐control—from age 10 to age 30, risk‐seeking and impulsivity are empirically distinct and develop in divergent ways that are consistent with the dual systems model. Changes in risk‐seeking and impulsivity also affect changes in crime, but their effects vary with age and changes in the other element. We discuss these findings and their implications for self‐control and the development of life‐course criminology. 相似文献

What motivates university scientists to identify practical applications for their research results and consider having them patent-protected? A wealth of research points towards a complex blend of factors, including organizational antecedents, social norms and personal-level expectations. Few studies, however, have attempted to investigate the effect of concrete incentives from the perspective of individual scientists’ decision-making. In this paper, we operationalize the propensity to patent and commercialize research results as the intention to submit an invention disclosure filing. We use scenario-based conjoint analysis to capture university scientists’ preference structures for different incentive policies. Results indicate that direct and indirect financial incentives are dominant drivers. In addition, a grace period that would allow for patenting and publishing in parallel and the inclusion of patents in academic performance assessments are worth considering, whereas the specific setup of the technology transfer organization and public recognition of achievements in form of an award appear to have limited effect. However, preferences for incentives and hence their effectiveness vary significantly across academic disciplines and ranks as well as with scientists’ working experience, patenting experience and research orientation. On this basis, we can derive more qualified recommendations for incentive system design. 相似文献

Veterans with mental health problems are a high-risk group for substance misuse difficulties and are over-represented in forensic settings. Yet, there are few substance misuse services available for this population. Evidence suggests that case management can provide effective interventions for veterans with substance misuse problems. However, there is little research to show its effectiveness in the UK. The present study reported on the implementation and preliminary outcomes of the Veterans Forensic Substance Misuses Service (VFSMS), piloted within a prison setting, to demonstrate the feasibility of the service. The VFSMS operated in four stages: Assessing needs, developing case management plans, providing bespoke support and developing discharge plans. Case studies were used to demonstrate this process, with measures of alcohol use and recovery showing outcomes for each case. Findings from three case studies suggested that case management was a feasible approach, with a range of interventions being used, including substance misuse and mental health services, plus housing and employment services. Outcome measures suggested that alcohol and substance misuse recovery improved following the VFSMS intervention. While the scope of the findings is limited, they suggested that case management is a feasible substance misuse intervention, with preliminary findings showing improvements in substance misuse outcomes. 相似文献

Die Festlegung von Konzentrationszonen für raumbedeutsame Vorhaben im Außenbereich muss nach der Rechtsprechung des Bundesverwaltungsgerichts auf einem gesamträumlichen Planungskonzept beruhen und den Anforderungen des Abwägungsgebots genügen. Danach kann der Träger der Regionalplanung auch dazu berechtigt sein, die Nutzungsmöglichkeit als typisierte Größe in die Abwägung einzustellen und das Eigentümerinteresse an der Nutzung verallgemeinernd zu unterstellen. Der folgende Beitrag zeigt auf, in welcher Phase des Abwägungsvorgangs Typisierungen oder Unterstellungen in Betracht kommen und welchen Beschränkungen sie unterliegen. 相似文献
