Effects of temporal abiotic drivers on the dynamics of an allometric trophic network model
2023
Current ecological research and ecosystem management call for improved understanding of the abiotic drivers of community dynamics, including temperature effects on species interactions and biomass accumulation. Allometric trophic network (ATN) models, which simulate material (carbon) transfer in trophic networks from producers to consumers based on mass-specific metabolic rates, provide an attractive framework to study consumer–resource interactions from organisms to ecosystems. However, the developed ATN models rarely consider temporal changes in some key abiotic drivers that affect, for example, consumer metabolism and producer growth. Here, we evaluate how temporal changes in carrying ca…
Chronic Background Radiation Correlates With Sperm Swimming Endurance in Bank Voles From Chernobyl
2022
Sperm quantity and quality are key features explaining intra- and interspecific variation in male reproductive success. Spermatogenesis is sensitive to ionizing radiation and laboratory studies investigating acute effects of ionizing radiation have indeed found negative effects of radiation on sperm quantity and quality. In nature, levels of natural background radiation vary dramatically, and chronic effects of low-level background radiation exposure on spermatogenesis are poorly understood. The Chernobyl region offers a unique research opportunity for investigating effects of chronic low-level ionizing radiation on reproductive properties of wild organisms. We captured male bank voles (Myo…
Whether and How Social Work Could Address the Long-Term Socio-environmental Risks Caused by the Mining Industry in Northern Finland
2018
Despite underlining the importance of the commitment of states and international organizations, the discourse on human security is seldom explicit about who the actors or frontline workers are that operationalize the framework. One such group of practitioners that is possibly involved, but largely unacknowledged, is social workers, especially as social work as a discipline, profession and social movement has a value base and overall goals that are very similar to the human security approach. In social work, the categories of economic, food, environmental and community security fall within the discourse of human security, particularly with the currently evolving ecosocial (ecological/environ…
The effectiveness of rural versus urban nonprofit organisations in the Democratic Republic of Congo
2017
The Democratic Republic of Congo (DRC) is a country with high natural resources, but it has suffered from decades of civil wars and social turmoil, being heavily aid-dependent. In the DRC, several Nonprofit Organisations (NPOs) are major players in fighting poverty and enhancing welfare. This research aims to analyse the effectiveness of small NPOs in improving poor peoples’ lives through health, education, and economic activities. Two NPOs working in the DRC, one in a rural and the other in an urban area, are compared by researching the aid sites and surveying 201 households (aid beneficiaries). Our case observations and the survey results facilitate analysing the mission accomplishment, e…
Finnish forest-based companies in transition to the circular bioeconomy : drivers, organizational resources and innovations
2020
Abstract Forest-based businesses are the center of the transition to the sustainable and competitive circular bioeconomy in Finland. This study explores the transition of Finnish FBS firms to new business models, with a focus on the organizational resources and capabilities needed for transition. It also identifies the important elements in the business environment and the role of innovations in this process. The study uses thematic interviews with managers from various FBS firms and companies from interfacing sectors, all of which have operations in Finland. Despite the differences between firms, the study finds many common drivers and resources that FBS companies highlight as significant …
Why Do Managers Leave Their Organization? : Investigating the Role of Ethical Organizational Culture in Managerial Turnover
2016
The aim of the present longitudinal study was to quantitatively examine whether an ethical organizational culture predicts turnover among managers. To complement the quantitative results, a further important aim was to examine the self-reported reasons behind manager turnover, and the associations of ethical organizational culture with these reasons. The participants were Finnish managers working in technical and commercial fields. Logistic regression analyses indicated that, of the eight virtues investigated, congruency of supervisors, congruency of senior management, discussability, and sanctionability were negatively related to manager turnover. The results also revealed that the turnove…
Le recrutement des jeunes docteurs dans le secteur privé
2007
This paper explores the relationship between the characteristics of the doctoral training and the recruitment of young PhDs in the private sector in France. We used information from a national representative survey of 1246 PhDs graduated in 2001 and interviewed in 2004. We focus on the recruitment and PhD returns among research-based jobs and non-research jobs in the private sector. Our econometrics results show that access and wages in the R&D jobs strongly depends on previous labour experience during the PhD (participation in a research contract, private funding for the PhD). In addition, we find that PhD students who expressed a preference for academia pay a wage penalty when they access…
Pollution in strategic multilateral exchange: taxing emissions or trading on permit markets?
2022
We introduce polluting emissions in a sequential noncooperative oligopoly model of bilateral exchange. In one sector a leader and a follower use polluting technologies which create negative externalities on the payoffs of strategic traders who belong to the other sector. By modeling emissions as a negative externality, we show that the leader pollutes more (less) than the follower when strategies are substitutes (complements). Then, we consider the implementation of public policies to control the levels of emissions, namely two taxation mechanisms and a permit market. We study the effects of these public policies. Moreover, we determine the conditions under which these public policies can i…
Institutional Logics in Police Performance Indicator Development : A Comparative Case Study of Spain and Finland
2015
Police performance is not easily measurable and the organization and circumstances of police work vary among European countries. Further, police work is surrounded by multiple pressures to make it both economical and effective. Consequently, there are multiple institutional logics in decision-making which may affect the selection and the use of police key performance indicators (KPIs). The KPI selection and use processes reflect the institutional logics, though KPI use may also sometimes influence the institutional logics of police work. In this study, we analyze the KPIs and institutional logics in police work in Finland and Spain. A comparative case research approach is used in order to h…
Trade imbalances within the euro area and with respect to the rest of the world
2015
Abstract Many studies have explored the determinants of current account balances in Europe. However, only in a few studies has trade balance been decomposed into intra balance, trade balance vis-a-vis the euro area, and extra balance, trade balance vis-a-vis the rest of the world. This decomposition is necessary for us to understand why some core euro area countries are acting as financial intermediaries for the periphery countries. Furthermore, the determinants of intra and extra balances might be different because nominal exchange rate cannot adjust between the EMU countries while their financial markets are highly integrated. Thus, we apply this decomposition and supplement the previous …
