The economic value of olive plantation in rural areas. A study on a hill region between Italy and Slovenia
This study was undertaken with the primary purpose of assessing the welfare gain to local residents resulting from olive trees. A secondary but important aim was to underline the multifunctional role of olive farming. In fact, we know that olive plantation has potentially socially benefits. In particular, it has potentially a lot of positive social effects in rural areas depending on plantation characteristics and farming practices. Therefore, the first section of this paper reviews the main features connected to the multifunctional role of olive farming. Multifunctional role of olive farming is well known in the EU, but it is still needed the institutional intervention in favour of farmers, due to the structural difficulties of olive production sector. Later sections concentrate on a survey carried out in order to estimate the economic value of the rural landscape, focusing in particular on olive trees in a hill region between Italy and Slovenia. From the conducted survey we gauged citizens’ WTP to introduce olive trees in the landscape. Survey data was collected by means of questionnaires. We applied the Contingent Valuation Method (CVM) in order to assess the citizens’ Willingness To Pay (WTP) for specific rural landscape features. The paper ends with some conclusions about the positive results obtained in olive plantation valuation questions.olive plantation, multifunctionality, willingness to pay, rural landscape valuation, Community/Rural/Urban Development,

For what they are, not for what they bring: The signaling value of gender for financial resource acquisition in academic spin-offs
Due to the novelty of their technology base and the multiple goals pursued by their entrepreneurial teams, academic spin-offs (ASOs) suffer information asymmetries with investors that impair their ability to raise finance. In line with the signaling theory, we expect that observable features of an ASO can mitigate such information asymmetries, especially in conditions of higher uncertainty about the venture. We put forward that a larger share of capital owned by female shareholders adds to such uncertainty due to their outsider condition in academic entrepreneurship and the negative bias of investors against female entrepreneurs.
Through a multi-level Tobit regression on a sample of Italian ASOs, we find that the amount of private investment is negatively associated with the degree of female ownership and positively associated with the investment of the parent university and full professors. The latter two factors moderate the relationship between the degree of female ownership and private investment so that it becomes less negative.
The results provide evidence of the persisting gender gap in entrepreneurial finance and highlight the role of parent universities in closing such a gap

The dark side of leadership: A systematic review of creativity and innovation
It is believed that workplace creativity and innovation are fostered by positive leader behaviours and positive workplace relationships and hindered by the opposite. However, some challenge this view, arguing that creativity and innovation can actually be fostered when employees experience what is increasingly referred to as the dark side of leadership and workplace mistreatment. Research on this area is sparse, contradictory and overly confusing. We begin by defining the dark side of leadership and then provide a comprehensive systematic review of 145 empirical studies on the topic. We review research on a broad range of constructs related to leadership and workplace mistreatment, such as abusive supervision, authoritarian leadership, destructive leadership, narcissistic leadership and relationship conflict. Our review reports the main effects, summarizes the results of the mediating and moderating variables, and highlights methodological shortcomings of the past literature. On this basis, several recommendations are made to advance this field of research
Gene expression response of the alga Fucus virsoides (Fucales, Ochrophyta) to glyphosate solution exposure
Fucus virsoides is an ecologically important canopy-forming brown algae endemic to the Adriatic Sea. Once widespread in marine coastal areas, this species underwent a rapid population decline and is now confined to small residual areas. Although the reasons behind this progressive disappearance are still a matter of debate, F. virsoides may suffer, like other macroalgae, from the potential toxic effects of glyphosate-based herbicides. Here, through a transcriptomic approach, we investigate the molecular basis of the high susceptibility of this species to glyphosate solution, previously observed at the morphological and eco-physiological levels. By simulating runoff event in a factorial experiment, we exposed F. virsoides to glyphosate (Roundup\uae 2.0), either alone or in association with nutrient enrichment, highlighting significant alterations of gene expression profiles that were already visible after three days of exposure. In particular, glyphosate exposure determined the near-complete expression shutdown of several genes involved in photosynthesis, protein synthesis and stress response molecular pathways. Curiously, these detrimental effects were partially mitigated by nutrient supplementation, which may explain the survival of relict population in confined areas with high nutrient inputs. Our results show that glyphosate impairs the expression of genes involved in photosynthesis and protein synthesis in F. virsoides
CDK-dependent nuclear localization of B-Cyclin Clb1 promotes FEAR activation during meiosis I in budding yeast
Cyclin-dependent kinases (CDK) are master regulators of the cell cycle in eukaryotes. CDK activity is regulated by the presence, post-translational modification and spatial localization of its regulatory subunit cyclin. In budding yeast, the B-cyclin Clb1 is phosphorylated and localizes to the nucleus during meiosis I. However the functional significance of Clb1's phosphorylation and nuclear localization and their mutual dependency is unknown. In this paper, we demonstrate that meiosis-specific phosphorylation of Clb1 requires its import to the nucleus but not vice versa. While Clb1 phosphorylation is dependent on activity of both CDK and polo-like kinase Cdc5, its nuclear localization requires CDK but not Cdc5 activity. Furthermore we show that increased nuclear localization of Clb1 during meiosis enhances activation of FEAR (Cdc Fourteen Early Anaphase Release) pathway. We discuss the significance of our results in relation to regulation of exit from meiosis I
