El estudio de la motivación humana es un constructo altamente complejo y con una gran variabilidad de enfoques. La teoría de la autodeterminación (TAD) ha demostrado una relativa efectividad y consistencia en muchos aspectos relacionados con la salud, como por ejemplo el ejercicio físico, la alimentación, el sueño, el bienestar psicológico o el consumo de tabaco. Las investigaciones muestran que la motivación autodeterminada se corresponde con la motivación intrínseca y en cambio la motivación extrínseca y sus formas de regulación pueden corresponderse con comportamiento no autodeterminados, pudiendo llegar hasta la desmotivación. En este trabajo se formula una construcción teórica sobre este modelo, introduciendo la percepción de riesgo (PR) y la vulnerabilidad percibida (VP) como elementos que pueden variar el sentido final de la motivación e incluso mejorar alguna de sus regulaciones extrínsecas y la desmotivación. Una de las posibilidades teóricas que sugerimos para intentar neutralizar los tipos no autodeterminados es procurar aumentar la PR y la VP de la persona, ya que estando estas dos variables altas, la probabilidad de que la desmotivación aparezca se reduce significativamente, y las acciones forzadas de la regulación externa y la regulación introyectada pueden amortiguarse y aumentar la internalización lo que podría favorecer los comportamientos de salud.

In our daily lives, we often must predict how well we are going to perform in the future based on an evaluation of our current performance and an assessment of how much we will improve with practice. Such predictions can be used to decide whether to invest our time and energy in learning and, if we opt to invest, what rewards we may gain. This thesis investigated whether people are capable of tracking their own learning (i.e. current and future motor ability) and exploiting that information to make decisions related to task reward. In experiment one, participants performed a target aiming task under a visuomotor rotation such that they initially missed the target but gradually improved. After briefly practicing the task, they were asked to select rewards for hits and misses applied to subsequent performance in the task, where selecting a higher reward for hits came at a cost of receiving a lower reward for misses. We found that participants made decisions that were in the direction of optimal and therefore demonstrated knowledge of future task performance. In experiment two, participants learned a novel target aiming task in which they were rewarded for target hits. Every five trials, they could choose a target size which varied inversely with reward value. Although participants’ decisions deviated from optimal, a model suggested that they took into account both past performance, and predicted future performance, when making their decisions. Together, these experiments suggest that people are capable of tracking their own learning and using that information to make sensible decisions related to reward maximization.

Usinig original data on 1,5000 mandibles, but mainly previously published data, I present a overview of the distribution characteristics of mandibular torus and a hypothesis concerning its cause. Pedigree studies have established that genetic factors influence torus development. Extrinsic factors are strongly implicated by other evidence: prevalence among Arctic peoples, effect of dietary change, age regression, preponderance in males and on the right side, effect of cranial deformation, concurrence with palatine torus and maxillary alveolar exostoses, and clinical evidence. I propose that the primary factor is masticatory stress. According to a mechanism suggested by orthodontic research, the horizontal component of bite force tips the lower canine, premolars and first molar so that their root apices exert pressure on the periodontal membrane, causing formation of new bone on the lingual cortical plate of the alveolar process. Thus formed, the hyperostosis is vulnerable to trauma and its periosteal covering becomes bruised causing additional deposition of bone. Genes influence torus indirectly through their effect on occlusion. A patern of increased expressivity with incidence suggests that a quasicontinuous model may provide a better fit to pedigree data than single locus models previously tested.

A germinação das sementes depende de diversos fatores. Estes podem ser dependentes da própria semente: intrínsecos (tais como a constituição da semente ou a sua maturidade e vitalidade), ou extrínsecos (tais como a luz, a temperatura, a humidade, o oxigénio e as características do solo). No presente trabalho pretendemos estudar o efeito de um desses fatores - a luz - na germinação das sementes de rabanete (Raphanus sativus, L.). Sabe-se que certas sementes só germinam à luz (fotoblastismo positivo), outras só o fazem às escuras (fotoblastismo negativo) e que outras são indiferentes ao efeito da luz no que se refere à germinação (fotoblastismo neutro) (Sousa, Braga, Braga & Delachiave, 2008; Ribeiro et al., 2012). Com o nosso estudo pudemos perceber que as sementes do rabanete apresentam fotoblastismo neutro.

Bonuses – which are often used to mitigate principal-agent problems and to encourage employees to work harder – have increased tremendously in the financial sector during the last decade, and have often been seen as a contributing factor to the financial crisis of 2008. The recent European Union (EU) action to adopt a policy that restricts bonuses paid to bankers may seem promising at first, but this does not address the real issues behind variable rewards. Compensation policies should be changed to encourage responsible risk-taking and decision-making through the implementation of broader performance metrics, forfeitable holdbacks and hybrid bonds. Furthermore, a change in organisational culture is needed to improve ethical behaviour leading to a re-balancing of stakeholders’ interests in the financial sector.

Migration towards Europe has surged over the past few years, overwhelming government authorities at the national and EU levels, and fuelling a xenophobic, nationalist, populist discourse linking migrants to security threats. Despite positive advances in the courts and worthy national initiatives (such as Italy’s Operation Mare Nostrum), the EU’s governance of migration and borders has had disastrous effects on the human rights of migrants. These effects stem from the criminalisation of migrants, which pushes them towards more precarious migration routes, the widespread use of administrative detention and the processing of asylum claims under the Dublin system, and now the EU–Turkey agreement. Yet, this paper finds that with the right political leadership, the EU could adopt different policies in order to develop and implement a human rights-based approach to migration that would seek to reconcile security concerns with the human rights of migrants. Such an approach would enable member states to fully reap the rewards of a stable, cohesive, long-term migration plan that facilitates and governs mobility rather than restricts it at immense cost to the EU, the member states and individual migrants.

The aim of the study was to examine the relationships between Eysenck's primary personality factors and various aspects of religious orientation and practice. Some 400 UK undergraduates completed questionnaires constructed from the Batson and Schoenrade Religious Life Inventory (Batson & Schoenrade, 1991) and the Eysenck Personality Profiler (Eysenck, Barrett, Wilson, & Jackson, 1992). As is generally found, all the religious variables correlated negatively with the higher order personality factor of psychoticism. In contrast, among the primary factors, those associated with neuroticism appeared to be the strongest indicators of religiosity. In particular, all the primary traits classically linked to neuroticism correlate positively with the quest orientation. However, fewer primary traits predict religious behaviour in regression and of these, a sense of guilt is the greatest and a common predictor of extrinsic, intrinsic and quest religiosities. Upon factor analysis of the significant personality predictors together with the three religious orientations, the orientations formed a single discrete factor, which implies that extrinsic, intrinsic and quest religiosities have more in common with one another than with any of the personality traits included in the study. This suggests that religious awareness may itself be an important individual difference that is distinct from those generally associated with models of personality. (C) 2003 Elsevier Ltd.
