La genètica de les migracions humanes: Seguint el rastre de les migracions a través del nostre genoma
2014
La reconstruccio de les migracions humanes es possible gracies a la informacio aportada per diverses disciplines. L’estudi de la diversitat genetica de les poblacions humanes actuals ens revela quins han estat els esdeveniments demografics i moviments migratoris passats que han deixat una empremta en el nostre genoma. El coneixement dels moviments migratoris en temps prehistorics ens permet comprovar hipotesis proposades des d’altres disciplines cientifiques. De la mateixa manera, la distribucio de la diversitat genetica en el futur dependra, en gran part, de les intenses migracions humanes actuals facilitades pels avencos tecnologics.
The Diversification of Sicilian Farms: A Way to Sustainable Rural Development
2021
Rural areas still suffer from a lack of sustainable development, and the diversification of farms may be a step in the right direction. The paper provides a detailed picture of the diversification of Sicilian farms into tourism services. Specifically, we propose a simple indicator of localization intensity of agritourism farms and explore their spatial distribution at municipality level. Our study highlights that Sicilian farms rarely diversify into tourism services, despite being situated in attractive areas. That said, some significant spatial clusters of municipalities where agritourism farms are highly concentrated do emerge from the study.
DIVIDEND CONTROVERSY: A THEORETICAL APPROACH
2011
One of the major financial decisions for a public company is the dividend policy - the proportion in which the company decides to distribute profits to shareholders. The difficulty of the decision comes from the implications on firm value. There are conflicting points of view on dividend policy. Even if under ideal conditions (perfect markets) dividend policy is irrelevant (the theory of Modigliani and Miller), still the way in which companies behave shows that the dividend policy is relevant in practice. Market imperfections (taxes, information asymmetry, transaction costs) influence dividend policy. The aim of this paper is to present the major theories and findings related to dividend po…
Figli adulti di divorzi ostili
2021
L’articolo propone una rassegna della letteratura relativa agli effetti a breve e lungo termine del divorzio coniugale sui figli adulti e giovani adulti. La ricerca internazionale relativa alle conseguenze del divorzio sul benessere psi- cologico dei figli ha spesso trascurato l’impatto che l’evento separativo e i cam- biamenti ad esso connessi possono avere sulla vita e sulle scelte dei figli adul- ti. Il vissuto del sentirsi “intrappolati” nel conflitto coniugale sembra avere esiti a lungo termine e influenzare differentemente la relazione con il padre e con la madre. L’articolo, attraverso un’esemplificazione clinica, si concentra anche sulle conseguenze del divorzio sulla qualità delle …
La diretta applicabilità dei trattati nell’ordinamento italiano: quo vadis?
2022
The concept of ‘direct applicability’ and ‘self-executing’ nature of international norms is still object of intense debate in the international legal scholarship. In Italy, such a debate has attracted new attention in the light of a recent ruling of the Joint Sections of the Court of Cassation, according to which the norms enshrined in the European Convention of Human Rights are not directly applicable in domestic proceedings. Such a statement seems to derive from some terminological and legal mis-understanding. By summarizing the conclusions of the several authors which have dealt with this issue in a Special Section of the review, the present article formulates some conclusions. First, it…
On the semantic interpretation of complex causatives in Finnish: An experimental morphology approach
2009
It is well documented that in some languages, such as in Finnish, it is possible to stack derivational morphemes iteratively to word stems. However, such complex words are seldom used in real communication, and it is unclear whether they are interpreted compositionally in tandem with their morphological structure. Here I studied the matter by eliciting semantic interpretations from ten native speakers of Finnish for words whose complexity and morphemic content were systematically varied. The results show that although the frequency of semantic interpretation decreases linearly as a function of the number of morphemes in a word (contrary to the case of ungrammatical words where the semantic …
Recipes of success : the case of pulp and paper industry 1989-2015
2017
Explaining the variation in competitive positioning actions across firms in the face of environmental change has long inspired debates in the field of strategic management. Despite the importance of these questions, little effort has been done to examine the complex interdependencies among industry, organizational attributes, and strategic actions that potentially underlie the organizational performance in one model without controlling one or more of the three factors. Most of the studies on competitive dynamics primarily have focused on independently exploring the effects of organizational characteristics or the industry structure on competitive actions and reactions, which, in turn, impac…
Moderating cultural effects in a higher e-education context? Supervisor's tone of voice in recorded audio feedback
2017
Providing feedback to learners on their writing assignments is one of the most important and time-consuming tasks that a supervisor performs. In e-Education environments, especially in the case of distance learning, giving feedback becomes more challenging because there are often no opportunities for face-to-face interaction. Typically, a supervisor provides comments to learners in written form via email; however, the use of recorded audio feedback (RAF) in e-Education environments has become a viable alternative. This work in progress reports on learners’ perceptions of RAF in a multi-cultural higher eEducation context. Our observations indicate that learners tend to have positive feelings…
Effects of bioheapleaching technology utilizing metal mine emissions on fish in boreal freshwaters
2018
Emissions from metal mining activities are known to deteriorate the quality of aquatic habitats and impair the condition and reproductive potential of fish. Metal extraction by biomining methods has been considered to cause fewer emissions, but for example in Finland, the impacts of a bioheapleaching technology utilizing metal mine on the local freshwaters have been substantial. In this thesis, the impacts of the bioheapleaching mine emissions on three native fish species, brown trout (Salmo trutta) European perch (Perca fluviatilis) and whitefish (Coregonus lavaretus pallasi), were investigated. Manganese and sulphate concentrations have been elevated in the mining impacted waters, and in …
