Economic Sustainability of Italian Greenhouse Cherry Tomato
2014
Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, b…
Peut-on concilier un faible usage de pesticides, une bonne performance économique et environnementale ? Analyse d’un réseau national de fermes de dém…
2017
Feeding an increasing world population with a sustainable agriculture is one of the greatest challenges of this century. The reduction of the reliance on pesticides is a critical aspect in this quest for sustainability. Whether cropping systems with reduced reliance on pesticides would be able to reconcile the various components of sustainability remains however a matter of debate. Are they as productive and profitable than current mainstream cropping systems? Here the objective is to study the feasibility of a reduced reliance on pesticides in France. We used a unique dataset from a national network of more than thousand arable commercial farms between 2009 and 2011. Launched in the framew…
COVID-19 Lessons and Post-pandemic Recovery: A Case of Latvia.

The research was supported by the NATIONAL RESEARCH PROGRAMME “LATVIAN HERITAGE AND FUTURE CHALLENGES FOR THE SUSTAINABILITY OF THE STATE” project “CHALLENGES FOR THE LATVIAN STATE AND SOCIETY AND THE SOLUTIONS IN INTERNATIONAL CONTEXT" (INTERFRAME-LV, Project No.VPP-IZM-2018/1-0005).
Acting Agentically at Work: Developing a Short Measure of Professional Agency
2021
Although professional agency has become an increasingly crucial issue in work organizations, investigators lack a brief instrument to measure it. This paper introduces a short measure to explore professional agency at work. Our aim was to shorten the original 17-item Professional Agency Measure, while also exploring its usability for cross-validating questionnaire datasets, and investigating the relationship between professional agency and work engagement. Three dimensions of professional agency emerged, with three items per dimension, across the domains of healthcare, real estate services, and information technology (all within Finland). All the dimensions (Influencing at work, Participati…

THE INFLUENCE OF THE EXTERNAL ENVIRONMENT ON ORGANIZATIONS
2016
The dynamics and complexity of external environment causes changes in organizations’ overall activity. These can lead to disruptions in their work, with multiple implications, both internally and within the areas in which they act. Since the elements that are related to organizations ‘external environment do not evolve simultaneously in the same direction and with the same intensity, the effects triggered on these entities are different. The influences between organizations and their external environment are reciprocal: the former influence the environment through their products, services, whereas their outer environment influence organizations. Consequently, to increase the efficiency and …
Emerging conceptualisations on professional agency and learning
2017
This chapter provides an evaluative summary of the major contributions from the first section of this book, comprising conceptualisations on professional agency and work-related learning. The evaluation focuses on the differences, similarities, and strengths of the approaches and conceptualisations touched on. The focus is, first of all, on how the core meanings of agency and the agentic perspective are understood. Secondly, the approaches are addressed according to their view of how the contextual aspects of working life relate to agency. Thirdly, attention is given to the practical conclusions deriving from different understandings of agency. The present chapter thus elaborates how these …
Study engagement and burnout profiles among Finnish higher education students
2017
A person-oriented approach was applied to identify profiles of study engagement and burnout (i.e., exhaustion, cynicism, inadequacy) in higher education in a large and representative sample of 12,394 higher education students at different phases of their studies in universities and polytechnics in Finland. Four profiles were identified: Engaged (44%), engaged-exhausted (30%) inefficacious (19%) and burned-out (7%). The engaged students had the most positive engagement accompanied with the least burnout symptoms compared to other groups. The engaged-exhausted students experienced emotional exhaustion simultaneously with academic engagement. The inefficacious group had heightened experience o…
Prognostic and Predictive Role of Tumor-Infiltrating Lymphocytes (TILs) in Ovarian Cancer
2022
In the last decade, tumor-infiltrating lymphocytes (TILs) have been recognized as clinically relevant prognostic markers for improved survival, providing the immunological basis for the development of new therapeutic strategies and showing a significant prognostic and predictive role in several malignancies, including ovarian cancer (OC). In fact, many OCs show TILs whose typology and degree of infiltration have been shown to be strongly correlated with prognosis and survival. The OC histological subtype with the higher presence of TILs is the high-grade serous carcinoma (HGSC) followed by the endometrioid subtype, whereas mucinous and clear cell OCs seem to contain a lower percentage of TI…
