Health Effects Caused by Primary Fine Particulate Matter (PM2.5) Emitted from Buses in the Helsinki Metropolitan Area, Finland

Fine particle (PM(2.5)) emissions from traffic have been associated with premature mortality. The current work compares PM(2.5)-induced mortality in alternative public bus transportation strategies as being considered by the Helsinki Metropolitan Area Council, Finland. The current bus fleet and transportation volume is compared to four alternative hypothetical bus fleet strategies for the year 2020: (1) the current bus fleet for 2020 traffic volume, (2) modern diesel buses without particle traps, (3) diesel buses with particle traps, and (4) buses using natural gas engines. The average population PM(2.5) exposure level attributable to the bus emissions was determined for the 1996-1997 situation using PM(2.5) exposure measurements including elemental composition from the EXPOLIS-Helsinki study and similar element-based source apportionment of ambient PM(2.5) concentrations observed in the ULTRA study. Average population exposure to particles originating from the bus traffic in the year 2020 is assumed to be proportional to the bus emissions in each strategy. Associated mortality was calculated using dose-response relationships from two large cohort studies on PM(2.5) mortality from the United States. Estimated number of deaths per year (90% confidence intervals in parenthesis) associated with primary PM(2.5) emissions from buses in Helsinki Metropolitan Area in 2020 were 18 (0-55), 9 (0-27), 4 (0-14), and 3 (0-8) for the strategies 1-4, respectively. The relative differences in the associated mortalities for the alternative strategies are substantial, but the number of deaths in the lowest alternative, the gas buses, is only marginally lower than what would be achieved by diesel engines equipped with particle trap technology. The dose-response relationship and the emission factors were identified as the main sources of uncertainty in the model.     

Spatial Variation in Seasonal Water Poverty Index for Laos: An Application of Geographically Weighted Principal Component Analysis

In this paper we analyze the preferences about job security using tools from behavioral economics. We focus on the non-pecuniary value of job security and specifically whether this value depends on the current position of employees as tenured or non-tenured. Using a sample of 107 Israeli social workers, randomly allocated between tenured and non-tenured positions, we demonstrate that the non-pecuniary value of job security is about 20% of the wage. We also found that this value depends on the point of reference of the employees. Those with tenure place a higher value on job security, as do those with a higher level of loss aversion.     

Comparison of efficiencies of some symmetry tests around an unknown centre

In this paper, some recent and classical tests of symmetry are modified for the case of an unknown centre. The unknown centre is estimated with its α-trimmed mean estimator. The asymptotic behaviour of the new tests is explored. The local approximate Bahadur efficiency is used to compare the tests to each other as well as to some other tests.     

Pareto improving transition from a pay-as-you-go to a fully funded pension system in a model of endogenous growth

In this paper we investigate the possibility of Pareto improving social security reforms within a framework of endogenous growth. Belan et al. (1998) propose a transition from a pay-as-you-go (PAYG) pension system to a system of savings–subsidization. We follow this approach and prove that a Pareto improving conversion from the PAYG system to a fully funded one is possible. Finally, we compare the subsidy system with the fully funded system and discuss the problem of implementing the transition to the fully funded system.

Does customer or competitor performance drive operations prioritisation?

The purpose of this research is to identify the impact on operations managers of their perceptions of customer requirements and competitor performance on their determination of operations priorities. Data were obtained from a multiple respondent survey. Analysis involved an ordered choice model. The process of strategic prioritisation differs according to the specific performance dimension. Quality-based objectives are focused on the voice of the customer; cost-based objectives are influenced by a balance of importance to customer and performance against competitor. Other criteria (flexibility, dependability, speed) objectives are more influenced by perceptions of competitive benchmarking. This large sample survey of operations managers’ perceptions offers a valuable insight into their motivation for focusing on different operations criteria.     

User involvement and empowerment among asylum seekers in Norwegian reception centres

A considerable amount of literature has been published on conditions in reception centres for asylum seekers. The previous studies show that the life of residents in the centres is characterised by uncertainty, passivity, powerlessness and gradual disqualification. Drawing from data collected from asylum seekers and service providers in Norwegian reception centres, this article examines the tools used to counteract these processes. The article maintains that organised activities, such as language courses and user involvement in the form of cooperative councils, have an impact on the empowerment of asylum seekers. However, user motivation for participation and involvement in these arrangements is undermined, due to residents' responses on factors which operate both at the structural and relational level. The findings and questions raised in the article have wider implications for social work with asylum seekers in other European countries, as well as for current efforts being made by EU countries to regulate reception conditions for asylum seekers. Among other things, the authors relate their findings to reception standards as defined in the EU Directive on Reception Conditions for asylum seekers.     

Associations between stress at work and attitudes towards retirement in hospital physicians

There is a need to understand the associations between attitudes towards retirement in specific occupations and various psychosocial and work-related factors. This study identified correlates of retirement thoughts and retirement preference in hospital physicians. The sample comprised 447 (251 male and 196 female) physicians from three hospital districts in Finland. After adjustment for gender, age and salary, minor psychiatric morbidity increased likelihood of retirement thoughts and retirement preference. Retirement thoughts and retirement preference were more common in doctors reporting low job control, poor teamwork and unjust supervision than in doctors perceiving their working conditions more favorably. Work preference was associated with high overwork. The associations of work characteristics with retirement thoughts and retirement preference largely persisted after control for indicators of health and social circumstances. In conclusion, in addition to demographic and financial factors and health, retirement attitudes in hospital physicians seem to be related to organizational and managerial factors that are potentially amendable to intervention. This has implications for retaining hospital physicians who might otherwise retire.     

Study on a resource allocation formula for social services in Finland

This article considers how a specific need-based resource allocation formula for children's day care, income support, child welfare and other social services was developed. The formula is needed for the municipal allocation of state subsidies for social services, and the work was performed for the Ministry of Social Welfare and Health. Cross-sectional data were collected from the 436 Finnish municipalities and 37 small areas within the six largest cities. Because of the simultaneous relationship between supply and demand of services, two-stage least-square estimation and structural equations models were used in the analysis. After the effect of supply was removed from the service utilisation data, group-need factors (municipal variables) were found for these services. The new formula is financially and administratively feasible, transparent and reasonably simple.     

Expectation management for public sector organizations

Transparency and collecting stakeholder feedback are becoming the norm also in the public sector. Though much of feedback is related to stakeholder experiences, we propose that it is more beneficial to study expectations than experiences, as expectations affect future satisfaction. This study reports a process of collecting and analyzing stakeholder expectations in one health-care oriented public sector organization in Finland, and reports how these expectations and their implications were assessed by the organization's top management. The study suggests that to ensure stakeholder satisfaction and organizational success, top management should be guided to work through the feedback. We propose a “fix or fit” approach where expectations are first grouped and then analyzed as either something that requires changing of organizational functions, or as something that requires guiding of stakeholders’ expectations to fit existing functions.
