The Ecology of Hyperparasitoids.
2021
Hyperparasitoids are some of the most diverse members of insect food webs. True hyperparasitoids parasitize the larvae of other parasitoids, reaching these larvae with their ovipositor through the herbivore that hosts the parasitoid larva. During pupation, primary parasitoids also may be attacked by pseudohyperparasitoids that lay their eggs on the parasitoid (pre)pupae. By attacking primary parasitoids, hyperparasitoids may affect herbivore population dynamics, and they have been identified as a major challenge in biological control. Over the past decades, research, especially on aphid- and caterpillar-associated hyperparasitoids, has revealed that hyperparasitoids challenge rules on nutri…
Am I an Entrepreneur? Entrepreneurial Self-Identity as an Antecedent of Entrepreneurial Intention
2020
Although many studies have shown that entrepreneurial intention can be explained according to a theory of planned behavior, some scholars have provided interesting insights into the role of job self-identity perception—in particularly the ones related to entrepreneurship—as significant precursor of entrepreneurial intention. A questionnaire has been administered to graduates and students of an Italian university (N = 153). A hierarchical regression analysis controlling for demographic variables has been performed in order to test the research hypotheses. The findings of this study have been discussed, with particular attention paid to the unexpected, weak, or non-significant effects of perc…
The effects of corruption in entrepreneurial ecosystems on entrepreneurial intentions
2019
Although researchers have identified corruption as a factor capable of affecting the entrepreneurial ecosystem at the national level of analysis, scholars have reported conflicting results regarding the exact nature of the relationship between corruption and entrepreneurial intentions. This paper formulates some propositions about the complex relationship between corruption and entrepreneurship at different levels of analysis and it suggests and explores the socio-cultural consequences of such domains&rsquo
Education, Innovation and Economic Development
2016
Abstract Innovation is a concept that is more and more often used as a solution for increased competitiveness and economic development, either at organizational level or at a national one, but how is it created and what are the factors involved in the cycle education-innovation-economic and social development? This article intents to clarify the above mentioned cycle and provide an insight on what innovation means and what are its components, especially from a macroeconomic point of view. The results show how important innovation and other components like education are for the national and global economic development.
Exploring Environmental and Entrepreneurial Antecedents of Social Performance in Spanish Sports Clubs: A Symmetric and Asymmetric Approach
2020
The social function of non-profit sports clubs is undeniable, so analyzing the factors that influence their performance is vital. The aim of this study is to understand the influence of entrepreneurial factors (entrepreneurial orientation) and environmental factors (dynamism, hostility and complexity) on social performance using a symmetrical (Hierarchical regression model) and asymmetrical (qualitative comparative analysis) approach. The social performance of this particular type of organization is of great importance in an environment where sustainability from a social point of view is increasingly on the agenda of governments, organizations and society in general. A total of 209 Spanish …
Balancing ‘flexibility’ and ‘employability’: The changing role of general studies in the Finnish and Swedish VET curricula of the 1990s and 2010s
2019
This article analyses and compares the evolving role of general subjects in the curricula of initial upper secondary vocational education and training (VET) in Finland and Sweden during the 1990s and 2010s. The research illustrates how Bernstein’s concept of ‘pedagogic code’ supports comparative studies on principles guiding changes to curricula and how the role of general studies in VET has been redefined. The findings show that while a principle of ‘market relevance’ has been central to VET over the decades since the 1990s, it has been subject to varying interpretations. The shifts in interpretations have guided the organisation of VET in these two countries in different directions, incl…
Women Entrepreneurship and Performance
2011
Research on gendered performance in entrepreneurship is scarce, making the resolution of this issue a relevant research field. Chapter 7 starts by describing what we understand by performance, widening the concept from a financial to an operational or even a stakeholders’ satisfaction level. Next, we present some relevant research that suggests explanations for a gendered difference in entrepreneurs’ performance, mainly in terms of the existence of horizontal segregation, differences in size and in personal attributes of entrepreneurs. The discussion about gender differences in resource possession and accessibility is then introduced as a fundamental concern in this debate, by describing ec…
Developing a Pedagogical Framework and Design Principles for STEM Learning Environment Design
2020
The need for effective and attractive learning environments (LEs) for science, technology, engineering, and mathematics (STEM) has been internationally recognized. Additionally, the connection between STEM learning and cross-curricular skills such as creativity, innovation, and entrepreneurship has garnered attention. A deep theoretical and empirical understanding is required when designing STEM LEs. In this study, a pedagogical framework for STEM LEs has been developed based on feedback from students, aged 10–18 years old, teachers, school directors, parents, and STEM professionals, and supported by the literature. First, representatives of key stakeholder groups in Belarus, Finland, Germa…
Phytoplankton communities of polar regions–Diversity depending on environmental conditions and chemical anthropopressure
2015
The polar regions (Arctic and Antarctic) constitute up to 14% of the biosphere and offer some of the coldest and most arid Earth's environments. Nevertheless several oxygenic phototrophs including some higher plants, mosses, lichens, various algal groups and cyanobacteria, survive that harsh climate and create the base of the trophic relationships in fragile ecosystems of polar environments. Ecosystems in polar regions are characterized by low primary productivity and slow growth rates, therefore they are more vulnerable to disturbance, than those in temperate regions. From this reason, chemical contaminants influencing the growth of photoautotrophic producers might induce serious disorders…
Trawling disturbance effects on the trophic ecology of two co-generic Astropectinid species
2015
Physical disturbance by trawling can have both negative and positive effects on populations of scavenging benthic organisms. In the present study the impact of fishing activity on feeding behaviour of the two Astropectinids, Astropecten bispinosus and A. irregularis , was assessed based on stomach contents analysis. The study was carried out along trawled seabed highlighting the positive response of the two facultative scavengers to carrion generated by trawl disturbance. Furthermore, there was greater food specialization in areas that were more heavily exploited by trawling. This specialisation could be linked to the availability of certain prey that results from the passage of fishing gea…
