'The Degree of Despair': The Disjointed Labour Market, the Impact of the Pandemics, the Expansion of Precarious Work among Youth and Its Effects on Young People's Life Trajectories, Life Chances and Political Mentalities - Public Trust; The Case of Greece

This paper focuses on the expansion of precarious forms of employment (temporary, seasonal, part-time jobs etc.) and on the impact this expansion has on young peoples' key determinants of life course. Based on both secondary quantitative-data analysis and primary qualitative research, the paper analyzes the state of play regarding precarious work among youth both in the EU and (mainly) in Greece, while it highlights the impact of the pandemic and the subsequent Recession in the abovementioned. The paper also explores the various aspects and facets of the impact of precarious employment in young peoples' life trajectories. Key findings include: a) the strong correlation between precarious employment, social vulnerability and risk of poverty, b) the fact that, during the pandemic, the "labour market slack" in Greece hit young people aged 15-24 more than people aged 25-54, further widening their precariousness, c) that there is a wider tendency to expand and "normalize" the forms of precarious employment among youth, concerning, especially, the combination of declared and undeclared work, d) that a new labour market dualization is formed, e) that both the pandemic and the subsequent restrictive measures have had a significant impact on the majority of precarious young people, effectively causing a rupture in their already precarious life course and f) that all the abovementioned have a severe impact on key determinants of political behavior - mentalities as well as on public trust among young people. The paper is based on an ongoing Research Project, co-financed by Greece and the European Union (European Social Fund- ESF) through the Operational Programme "Human Resources Development, Education and Lifelong Learning 2014-2020" in the context of the project "Precarious Work and Youth in today's Greece: secondary quantitative analysis, qualitative filed research and research-based policy proposals" (MIS 5048510)

Use of Fertigation and Municipal Solid Waste Compost for Greenhouse Pepper Cultivation

Municipal solid waste compost (MSWC) and/or fertigation used in greenhouse pepper (Capsicum annuum L.) cultivation with five different substrates with soil (S) and/or MSWC mixtures (0–5–10–20–40%) used with or without fertigation. Plants growth increased in 10–20% MSWC and fertigation enhanced mainly the plant height. Fruit number increased in S : MSWC 80 : 20 without fertilizer. Plant biomass increased as MSWC content increased. There were no differences regarding leaf fluoresces and plant yield. The addition of MSWC increased nutritive value (N, K, P, organic matter) of the substrate resulting in increased EC. Fruit fresh weight decreased (up to 31%) as plants grown in higher MSWC content. Fruit size fluctuated when different MSWC content used into the soil and the effects were mainly in fruit diameter rather than in fruit length. Interestingly, the scale of marketable fruits reduced as MSWC content increased into the substrate but addition of fertilizer reversed this trend and maintained the fruit marketability. MSWC affected quality parameters and reduced fruit acidity, total phenols but increased fruit lightness. No differences observed in fruit dry matter content, fruit firmness, green colour, total soluble sugars and EC of peppers and bacteria (total coliform and E. coli) units. Low content of MSWC improved plant growth and maintained fruit fresh weight for greenhouse pepper without affecting plant yield, while fertigation acted beneficially

Reductively PEGylated carbon nanomaterials and their use to nucleate 3D protein crystals: a comparison of dimensionality

A range of carbon nanomaterials, with varying dimensionality, were dispersed by a non-damaging and versatile chemical reduction route, and subsequently grafted by reaction with methoxy polyethylene glycol (mPEG) monobromides. The use of carbon nanomaterials with different geometries provides both a systematic comparison of surface modification chemistry and the opportunity to study factors affecting specific applications. Multi-walled carbon nanotubes, single-walled carbon nanotubes, graphite nanoplatelets, exfoliated few layer graphite and carbon black were functionalized with mPEG-Br, yielding grafting ratios relative to the nanocarbon framework between ca. 7 and 135 wt%; the products were characterised by Raman spectroscopy, TGA-MS, and electron microscopy. The functionalized materials were tested as nucleants by subjecting them to rigorous protein crystallization studies. Sparsely functionalized flat sheet geometries proved exceptionally effective at inducing crystallization of six proteins. This new class of nucleant, based on PEG grafted graphene-related materials, can be widely applied to promote the growth of 3D crystals suitable for X-ray crystallography. The association of the protein ferritin with functionalized exfoliated few layer graphite was directly visualized by transmission electron microscopy, illustrating the formation of ordered clusters of protein molecules critical to successful nucleation

How Historical and Social Aspirations Reshape the Relationship between Corporate Financial Performance and Corporate Social Responsibility?

Integrating the behavioral theory of the firm into the discussion on why firms behave in socially responsible ways, the study here develops and empirically tests hypotheses articulating when and how past corporate financial performance (CFP) might lead to more or less engagement in corporate social responsibility (CSR). Rather than treating historical and social aspirations as comparable performance benchmarks that yield similar behavioral responses, as most prior studies do, these two modes of performance comparison may induce signals that executives interpret differently, and therefore may lead to conflicting firm responses towards CSR initiatives. Using panel data pertaining to a large sample of U.S. firms, the study finds that historical and social performance comparisons have differential effects on CSR engagement. The findings describe how different interpretations of achievement influence firm’s engagement in secondary activities concerning environmental and social issues—a topic that has received very little attention in prior empirical research

A Step-by-Step Guide of (Fuzzy Set) Qualitative Comparative Analysis: From Theory to Practice via an Implementation in a B2B Context

One of the challenges researchers face in using an analytic method is to fully understand its underlying logic and find ways to successfully incorporate it into the research process. Qualitative Comparative Analysis (QCA) is an example in case, where such a challenge has been partly addressed so far, despite the increasing popularity of the method. Although QCA user guides are widely available, researchers may face difficulties in implementing the method to address real-world, complex social phenomena. To address this issue, the present methodological paper provides a step-by-step guide of QCA and links the background theory of the method to its practical implementation, via an example in the business-to business (B2B) context of open and closed innovation. The paper provides practitioners and researchers alike with a clear roadmap on how to exploit the full potential of the method in order to derive insightful explanations in applied data analysis

Expanding into new product lines in response to COVID-19: The interplay between firm age and performance aspirations

Unprecedented environmental shocks, like the outbreak of COVID-19, sometimes trigger firms to adjust to the new environment, by expanding quickly into new—relevant to the shock—product lines, as a means to capitalize on the booming demand of urgently needed supplies. This study examines the role of firm corporate liabilities, as the ones enclosed to firm age, in influencing the number of new product lines a firm introduces in response to the pandemic, and its reaction time to the shock. The way in which performance aspirations interfere in these managerial decisions is also examined. In testing hypotheses, we employ a novel multivariate matching approach, namely entropy balancing, which allows researchers to create balanced samples and accounts for the existence of non-random factors influencing the results. Using a sample of 973 manufacturers that introduced new product lines in response to COVID-19, our hypotheses, positively linking firm age to product line introductions, and negatively to response time to the environmental shock, are supported. Our results indicate that for firms with higher levels of performance above industry average, the positive influence of firm's age on the number of new product lines introduced is weaker than for firms with lower levels of performance above industry average

Innovation, Digital Technologies, and Sales Growth During Exogenous Shocks

We investigate how the introduction of different types of innovation and the adoption of various digital technologies during exogenous shocks, influence firms' sales growth. By drawing from a sample of 1979 firms from the Caribbean small island developing states (SIDS) during the COVID-19 pandemic, we show that although some innovation types enhance sales growth, others are not as important and can even reduce revenue over time. Moreover, by examining the interrelationship between innovation and digital technologies we unveil situations where the simultaneous introduction of certain types of innovations with specific digital tools further enhances sales growth and other instances where rigidities arise that impair sales growth. This study furthers our understanding of whether and how innovation, digital technologies, and their interaction, enable firms to positively respond to the challenges of exogenous shocks

Mining Twitter lists to extract brand-related associative information for celebrity endorsement

Twitter lists (i.e., curated collections of Twitter accounts) are user-generated and serve primarily as a tool to group other users. Grouping judgments are grounded in the implicit assumption that co-listed members share common associations. As such, Twitter lists are ideal for directly exploring associative links between brands and/or other entities. This research capitalizes on Twitter list membership data to provide a new metric indicating the similarity of users’ list membership profiles. This metric is used as a proxy for perceptions of brand–celebrity (mis)fit (i.e., the degree of congruency or similarity between the celebrity and the brand) in celebrity endorsement situations, where a celebrity's fame or social status is used to promote a brand. To validate the accuracy of the method, we compare the list similarity metric with directly elicited survey data for a test set of 62 celebrities and 64 brands, ranging across eight industry sectors. This research contributes to the extant literature of studies extracting brand-related associative information (i.e., information held in consumers’ memory that contains the meaning of a brand) from large volumes of consumer online data. This research also introduces new ways of data mining to operational research literature and provides managers with a new methodology to directly infer perceptions of brand–celebrity (mis)fit
