A “Swedish” actuarial balance for a notional defined contribution pension scheme with disability and minimum pension benefits 下载免费PDF全文
Juan M. Pérez‐Salamero González Manuel Ventura‐Marco Carlos Vidal‐Meliá 《International social security review》2017,70(3):79-104
This article proposes a “Swedish” type actuarial balance sheet (ABS) for a notional defined contribution (NDC) scheme with disability and minimum pension benefits. The proposed ABS splits the pension system in two parts: the pure NDC part and the redistributive part, which includes the assets and liabilities originating from non‐contributory rights. The article contains a numerical example that sheds light on the real applicability of our proposal. The model has practical implications that could be of interest to policy‐makers, given that it integrates actuarial and social aspects of public pensions and discloses the real cost of redistribution through minimum pensions. 相似文献

Ironworkers frequently perform heavy lifting tasks in teams of two or four workers. Team lifting could potentially lead to a higher variation in peak lumbar compression forces than lifts performed by one worker, resulting in higher maximal peak lumbar compression forces. This study compared single-worker lifts (25-kg, iron bar) to two-worker lifts (50-kg, two iron bars) and to four-worker lifts (100-kg, iron lattice). Inverse dynamics was used to calculate peak lumbar compression forces. To assess the variability in peak lumbar loading, all three lifting tasks were performed six times. Results showed that the variability in peak lumbar loading was somewhat higher in the team lifts compared to the single-worker lifts. However, despite this increased variability, team lifts did not result in larger maximum peak lumbar compression forces. Therefore, it was concluded that, from a biomechanical point of view, team lifting does not result in an additional risk for low back complaints in ironworkers. 相似文献

Lifting and carrying heavy loads occur frequently among ironworkers and result in high prevalence and incidence rates of low back complaints, injuries and work-disability. From a health perspective, little information is available on the effect of team lifting on work demands and workload. Therefore, the objective of this study was to compare the effects of team lifting of maximally 50 kg by two ironworkers (T50) with team lifting of maximally 100 kg by four ironworkers (T100). This study combined a field and laboratory study with the following outcome measures: duration and frequency of tasks and activities, energetic workload, perceived discomfort and maximal compression forces (Fc peak) on the low back. The physical work demands and workload of an individual iron worker during manual handling of rebar materials of 100 kg with four workers did not differ from the manual handling of rebar materials of 50 kg with two workers, with the exception of low back discomfort and Fc peak. The biomechanical workload of the low back exceeded for both T50 and T100 the NIOSH threshold limit of 3400N. Therefore, mechanical transport or other effective design solutions should be considered to reduce the biomechanical workload of the low back and the accompanying health risks among iron workers. 相似文献

The purpose of this study was to compare the neuromuscular adaptations produced by strength-training (ST) and power-training (PT) regimens in older individuals. Participants were balanced by quadriceps cross-sectional area (CSA) and leg-press 1-repetition maximum and randomly assigned to an ST group (n = 14; 63.6 ± 4.0 yr, 79.7 ± 17.2 kg, and 163.9 ± 9.8 cm), a PT group (n = 16; 64.9 ± 3.9 yr, 63.9 ± 11.9 kg, and 157.4 ± 7.7 cm), or a control group (n = 13; 63.0 ± 4.0 yr, 67.2 ± 10.8 kg, and 159.8 ± 6.8 cm). ST and PT were equally effective in increasing (a) maximum dynamic and isometric strength (p < .05), (b) increasing quadriceps muscle CSA (p < .05), and (c) decreasing electrical mechanical delay of the vastus lateralis muscle (p < .05). There were no significant changes in neuromuscular activation after training. The novel finding of the current study is that PT seems to be an attractive alternative to regular ST to maintain and improve muscle mass. 相似文献

Emerging evidence revealed that honesty and trustworthiness are important drivers of the impression-formation process. Questions remain, however, regarding the role of these moral attributes in guiding real and concrete behaviors. Filling this gap, the present study investigated the influence of honesty on a nonverbal behavior that regulates social interactions: behavioral synchrony. Movements were recorded while participants interacted with a partner who was depicted as honest (versus dishonest) or as friendly (versus unfriendly). Results showed that synchrony was affected only by the honesty of the partner. Specifically, the more the interaction partner lacked honesty, the lower the perceived similarity between the self and the interaction partner, which in turn diminished the promptness to engage in behavioral synchrony. Our findings connected the literature on behavioral synchrony with that on the implication of morality for social perception, revealing the key role of the honesty facet of moral character in shaping nonverbal behaviors. 相似文献

Youth engagement is increasingly recognized as a preferred approach and often necessary step in the treatment of emotional and behavioral disorders. The purpose of this study was to explore the degree and quality of youth engagement in the therapeutic process, compare engagement scores between youth accessing residential and day treatment, and explore the association between engagement and interpersonal difficulties in a sample of youth with an emotional and/or behavior disorder in residential and day treatment programs based in Southern Ontario. Cross-sectional surveys of standardized measures were administered to youth and a separate survey to their Prime Workers. Relevant constructs included client engagement (as rated by youth and Prime Workers), and youth-rated behavioral screen, interpersonal problems and family functioning. Both Prime Workers and youth rated youth as moderately high in their level of engagement in therapy. Furthermore, Prime Worker and youth ratings did not significantly differ statistically, suggesting that youth may have actually engaged at a moderate level. Interpersonal problems were shown to be negatively associated with youth engagement, and family functioning approached significance for only youth in residential treatment. Assessing youth engagement during the treatment process as an intervention technique may highlight areas where greater clinical efforts are needed. Future considerations include testing methods of sharing and discussing results of an engagement measure within the context of a one-on-one clinical encounter with youth. 相似文献

In the last few decades, a perspective on how to resolve wicked social problems has become increasingly prominent: the cultural theory pioneered by anthropologist Dame Mary Douglas. So far, the empirical evidence garnered in support of this approach has mostly been of a qualitative nature. Cultural theory has fared less well in survey-based, statistical tests. However, several features make it hard to test the theory with questionnaires. We overcome this research dilemma by showing how cultural theory can be tested with observational and experimental tests developed in cross-cultural psychology. We argue that this is possible due to the remarkable overlap between concepts and theories in cross-cultural psychology and Douglas' approach. We present five research designs that add up to a rigorous test of cultural theory. Finally, we sketch some contributions that cultural theory could make to the further development of cross-cultural psychology, as well as to efforts to resolve wicked problems, if it were thus confirmed. 相似文献

In the last two decades or so, globalisation has prompted a great deal of attention in the study of the international organisation of production, with in-depth industry studies on its welfare effects, both for firms and for workers. Outcomes did not prove a unique direction of effects, although the heterogeneous firms?? approach emphasised the intra-industry reallocation through intra-sectoral international competition. Thus, differences in the inner structure of companies filled the gap on the micro-level analysis that featured the study of international trade for several decades, although there is still the need to understand the effects of internationalisation on local systems of production and link such results to the consolidated meso-level of analysis of trade flows. Thanks to the microdata provided by the Italian Statistical Office (ISTAT), we are able to access information on the presence of Italian firms abroad, distinguished by geographical area of origin, destination and industry and check for their influence on affiliates?? structure and performance through appropriate indicators. 相似文献

Kernel density estimation for multivariate, circular data has been formulated only when the sample space is the sphere, but theory for the torus would also be useful. For data lying on a d-dimensional torus (d?1), we discuss kernel estimation of a density, its mixed partial derivatives, and their squared functionals. We introduce a specific class of product kernels whose order is suitably defined in such a way to obtain L2-risk formulas whose structure can be compared to their Euclidean counterparts. Our kernels are based on circular densities; however, we also discuss smaller bias estimation involving negative kernels which are functions of circular densities. Practical rules for selecting the smoothing degree, based on cross-validation, bootstrap and plug-in ideas are derived. Moreover, we provide specific results on the use of kernels based on the von Mises density. Finally, real-data examples and simulation studies illustrate the findings. 相似文献

We present original estimates of the quality of targeting of conditional cash transfer (CCT) and non‐contributory pension (NCP) programmes in Latin America and the Caribbean. Our contribution is novel because we use both national and international poverty lines; provide differentiated estimates for urban and rural areas; and compare the CCT and NCP programmes. We show that leakage to the non‐poor coexists with pervasive under‐coverage of all poor, including the extreme poor. On average, the CCTs cover only 50.5% of the extreme poor in households with children under 18 years of age. Similarly, the NCPs cover only 50.9% of the extreme poor in households with elderly members who do not receive a contributory pension. At the same time, 40.4% of CCT beneficiaries and 50.1% of NCP beneficiaries are not poor, highlighting the potential need for re‐targeting and re‐certification. In most countries, re‐targeting could produce a substantial double benefit in terms of poverty reduction and fiscal savings. 相似文献
