The computational role of short-term plasticity and the balance of excitation and inhibition in neural microcircuits: experimental and theoretical analysis

The computations performed by the brain ultimately rely on the functional connectivity between neurons embedded in complex networks. It is well known that the neuronal connections, the synapses, are plastic, i.e. the contribution of each presynaptic neuron to the firing of a postsynaptic neuron can be independently adjusted. The modulation of effective synaptic strength can occur on time scales that range from tens or hundreds of milliseconds, to tens of minutes or hours, to days, and may involve pre- and/or post-synaptic modifications. The collection of these mechanisms is generally believed to underlie learning and memory and, hence, it is fundamental to understand their consequences in the behavior of neurons.(...)

O dever de obediência a ordens ilegais na Guarda Nacional Republicana

The Republican National Guard (GNR) is a military structure and hierarchical force where discipline and obedience is a serious matter, but at the same time, the scope of its activity relates to the protection of the rights, freedoms and guarantees of citizens and the primacy of public interest. While security force, GNR ensures democratic law, guarantee the internal security and the rights of citizens. The controversial issue that lies at the heart of this work its related with the balance between the hierarchy and the written law. The hierarchy, also established by law, with given powers, exist to apply the law. However, the rule of law has exceptions. Which institute to prioritize, hierarchy or the law. And within the law, its rules or the exceptions. Who decides? The GNR's officers have to obey the laws and regulations and comply with the accuracy and timeliness determinations, orders and instructions issued by a superior, given in terms of service, as long as does not involve the practice of crime. The GNR´s officer with command tasks exercises power of authority inherent in these functions, and the corresponding disciplinary authority, being responsible for acts by himself or by his order are practiced. Identify situations of exception to law enforcement, the situations in which one must obey illegal orders, is difficult and thankless, it requires conferred authority and raises the weight of responsibility for decisions and orders issued.

A intervenção dos orgãos de polícia criminal em sede de julgamento

Currently, Portugal assumes itself as a democratic rule of substantive law State, sustained by a legal system seeking the right balance between the guarantee of fundamental rights and freedoms constitutional foreseen in Portugal’s Fundamental Law and criminal persecution. The architecture of the penal code lies with, roughly speaking, a accusatory basic structure, “deliberately attached to one of the most remarkable achievements of the civilizational democratic progress, and by obedience to the constitutional commandment”, in balance with the official investigation principle, valid both for the purpose of prosecution and trial. Regarding the principle of non self-incrimination - nemo tenetur se ipsum accusare, briefly defined as the defendant’s right of not being obliged to contribute to the self-incrimination, it should be stressed that there isn’t an explicit consecration in the Portuguese Constitution, being commonly accepted in an implicit constitutional prediction and deriving from other constitutional rights and principles, first and foremost, the meaning and scope of the concept of democratic rule of Law State, embedded in the Fundamental Law, and in the guidelines of the constitutional principles of human person dignity, freedom of action and the presumption of innocence. In any case, about the (in) applicability of the principle of the prohibition of self-incrimination to the Criminal Police Bodies in the trial hearing in Court, and sharing an idea of Guedes Valente, the truth is that the exercise of criminal action must tread a transparent path and non-compliant with methods to obtain evidence that violate the law, the public order or in violation of democratic principles and loyalty (Guedes Valente, 2013, p. 484). Within the framework of the penal process relating to the trial, which is assumed as the true phase of the process, the witness represents a relevant figure for the administration of criminal justice, for the testimonial proof is, in the idea of Othmar Jauernig, the worst proof of evidence, but also being the most frequent (Jauernig, 1998, p. 289). As coadjutant of the Public Prosecutor and, in specific cases, the investigating judge, the Criminal Police Bodies are invested with high responsibility, being "the arms and eyes of Judicial Authorities in pursuing the criminal investigation..." which has as ultimate goal the fulfillment of the Law pursuing the defense of society" (Guedes Valente, 2013, p. 485). It is in this context and as a witness that, throughout operational career, the Criminal Police Bodies are required to be at the trial hearing and clarify the Court with its view about the facts relating to occurrences of criminal context, thus contributing very significantly and, in some cases, decisively for the proper administration of the portuguese criminal justice. With regards to the intervention of Criminal Police Bodies in the trial hearing in Court, it’s important that they pay attention to a set of standards concerning the preparation of the testimony, the very provision of the testimony and, also, to its conclusion. Be emphasized that these guidelines may become crucial for the quality of the police testimony at the trial hearing, thus leading to an improvement of the enforcement of justice system. In this vein, while preparing the testimony, the Criminal Police Bodies must present itself in court with proper clothing, to read before and carefully the case files, to debate the facts being judged with other Criminal Police Bodies and prepare potential questions. Later, while giving his testimony during the trial, the Criminal Police Bodies must, summing up, to take the oath in a convincing manner, to feel comfortable, to start well by convincingly answering the first question, keep an attitude of serenity, to adopt an attitude of collaboration, to avoid the reading of documents, to demonstrate deference and seriousness before the judicial operators, to use simple and objective language, to adopt a fluent speech, to use nonverbal language correctly, to avoid spontaneity responding only to what is asked, to report only the truth, to avoid hesitations and contradictions, to be impartial and to maintain eye contact with the judge. Finally, at the conclusion of the testimony, the Criminal Police Bodies should rise in a smooth manner, avoiding to show relief, resentment or satisfaction, leaving a credible and professional image and, without much formality, requesting the judge permission to leave the courtroom. As final note, it’s important to stress that "The intervention of the Police Criminal Bodies in the trial hearing in Court” encloses itself on a theme of crucial importance not only for members of the Police and Security Forces, who must welcome this subject with the utmost seriousness and professionalism, but also for the proper administration of the criminal justice system in Portugal.

Impact of corporate social responsibility in the European pharmaceutical market

The objective of this master thesis is to evaluate the impact of CSR measures in the financial performance of the European pharmaceutical industry. By definition, CSR measures is quantified as corporate social disclosure considering the published CSR keywords on the annual reports of the selected companies, over four fiscal years (2010-2013). The financial performance of the companies were measured as return on assets (ROA) and Tobin’s Q. In order to defend the hypothesis developed, a multivariate regression is performed. The results obtained show no significant impact on the financial performance of a company nor in the short-time, nor in the long-time. Moreover, by comparison with other studies, it was possible to conclude that the financial performance is differently affected when considering different industries.

Corporate social responsibility

There is general consensus nowadays that CSR is not just altruistic do-gooding but rather a way for both companies and society to prosper. Companies themselves increasingly recognize that their sustainability depends on their willingness to assume responsibility for social and environmental issues. Academic research has, in the past, tried to theorize exactly how CSR improves business, employee satisfaction and productivity. However, few studies have a) separated the different effects of internal CSR and external CSR and b) studied these effects in times of internal organizational distrust. Hence, this paper examines the relationship between each type of CSR with two outcome variables related to employee attitudes: affective organizational commitment (AOC) and turnover intentions (TI). Furthermore, it investigates whether organizational distrust works as a moderator in each of these relationships by testing the hypothesis using a sample of 212 employees from a company that is currently going through a moment of internal crisis. Findings suggest that although all variables are strongly correlated, distrust works as a moderator for external CSR but not for internal CSR. The theoretical and practical implications of these findings conclude the paper.

Effects of corporate social responsibility on brand reputation and brand identification with children

This study aims to understand children‟s perceptions of Corporate Social Responsibility (CSR) initiatives and its effect on the brand, namely Reputation and Identification.
