River bioassessment and the preservation of threatened species: Towards acceptable biological quality criteria

2010

Abstract A central objective of environmental management is to maintain biodiversity, including populations of threatened species. Freshwater ecosystems are increasingly assessed by their biotic properties, but whether the resulting classifications of biotic condition are sufficient to protect species with conservation status has received very little consideration. We used data from 225 reference and impacted river sites from Finland to examine whether the occurrence and abundance of threatened macroinvertebrate species (TS) are associated with a commonly used estimate of biological condition (Observed-to-Expected number of predicted taxa of macroinvertebrates or O/E-ratio of taxonomic comp…

Intrinsic competition between two European egg parasitoids of the brown marmorated stink bug

2020

Following the accidental introduction and spread of the invasive polyphagous agricultural pest Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), the two European egg parasitoids Anastatus bifasciatus (Geoffroy) (Hymenoptera: Eupelmidae) and Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) have been investigated for inundative biological control. Since the competititve outcome between the two generalist parasitoids is difficult to predict, intrinsic competition was investigated with a time-course development study. Both species readily oviposited in H. halys eggs containing eggs and early instar larvae of the competitor, but oviposition decreased when eggs contained late insta…

INTEGRATION IN LATVIA: FLOWS AND EBBS IN NATIONAL AND EUROPEAN CONTEXT

2016

Russian-speaking communities in the member states of the European Union (EU), especially the Baltic States and Germany, have earned special attention, in recent years, as subjects of important integration policies, on one hand, and the main targets of Russia’s propagandist efforts, on the other. Because a significant part of Russian-speaking communities accepted these efforts, questions were raised concerning the effectiveness of previous integration policies to strengthen the national identity and invoke a feeling of political togetherness. Thus the factors fostering and triggering integration and the relations between civic and ethnocultural components of integration are of wide interest.…

The socioeconomic impacts of local energy programmes: a case study of Avrig, Romania

2014

Purpose – The purpose of this paper is to investigate the expected economic and social effects of the “Local Energy Plan” – a programme of the local administration that aims to transform the Romanian town Avrig until 2020 into an energy independent town relying exclusively on renewable energy resources. Design/methodology/approach – The study uses a mixed-method approach to investigate the effects of a small town's transition to renewable energy. This approach consists of a series of in-depth interviews with the local authorities, investors, other representatives of the business sector and citizens of Avrig and economic modelling to determine the direct effects generated by the implementat…

Getting support in polarized societies: Income, social networks, and socioeconomic context

2013

AbstractThis paper explores how unequal resources and social and economic polarization affects the size of social networks and their use to access resources. We argue that individual resource position generates divergent expectations with regard to the impact of polarization on the size of networks on one hand, and their usefulness for accessing resources on the other. Social and economic polarization encourages reliance on informal networks, but those at the bottom of the social structure are forced to rely on more extensive networks than the wealthy to compensate for their isolated and underprivileged position. At the same time, social and economic polarization limits the resources the po…

Beyond the Family and the Household: Occupational Family Networks

2009

Although families and kinship have been studied extensively from a historical perspective, less attention has been paid to their significance and role in the formation of local social networks.This study makes use of extensive Finnish records of godparentage to map local networks to analyze the factors (kinship, work relations, neighborhood, friendship) that influenced their formation. It argues that, in the context of a closed industrial community, occupation and kinship were the major cornerstones of these networks. Only after work-related inequality was slowly eliminated in the early twentieth century did kinship begin to gain ground as the main influencing factor.

Social Inequalities in the French Education System : The Joint Effect of Individual and Contextual Factors

2000

This paper presents a synthetic picture of social inequalities in pupils' scholastic careers in France. Individual factors such as socio-economic backgroun remain important for both academic results from the beginning of schooling on and option and streaming choices at the secondary level. Moreover, families have unequal resources to manage their children's schooling careers in a system which is becoming more complex and decentralized. This means that contextual factors are also very important. Decentralization has in fact increased the importance of choice of schooling context : the class or the school attented does make a difference and this has the effect of widening social gaps in acade…

Personal Employability and employment outcomes in a university sample: a study before and after COVID-19

2021

[EN] Labour market uncertainty makes difficult to get (and keep) a high-quality job even for graduate students. Moreover, this situation has been worsened due to the COVID-19 pandemic. The aim of this study is to test the influence that personal employability has on maintaining (or being able to find a new) high-quality job in a sample of young university graduates that faced the job market crisis caused by the COVID-19 pandemic. We focus on the four personal employability dimensions of Fugate et al.’s (2004) model: career identity, personal adaptability, human capital, and social capital. Our hypotheses state that the four dimensions of employability are positively related with employment …

Towards E-Government in a Sub-Saharan African Country

2006

ABSTRACT The use of information communication technologies (ICT) in governance is growing rapidly in many parts of the world. Developing countries in Africa are also making efforts to harness the new technology. In this paper, we provide useful insights regarding the impediments and initiatives of e-government in Nigeria, a Sub-Saharan African (SSA) country. The main problems facing the emergence of e-government in Nigeria have their roots in socioeconomic inadequacies that have plagued several countries in the SSA region. Some of the problems discussed include poor organizational skills, attitudinal problems, inadequate infrastructural support, and poor or unavailable human capital resourc…
