The activism of institutional investors tends more and more toward the supervision and control of the behavior of the managers of big companies. In this article, we present a model based on the creation of an activism index that lets us evaluate such activism's effect on the sensitivity of the investment policies of a company in the face of financial variables and market variables . To test our assertions, we analyze firm-level data for United Kingdom , Germany, France, Denmark, and (...) Spain during the period 1995-2004. Our results point to a significant reduction in the sensitivity of company investment decisions in the face of these variables, especially relative to intangible capital, as a result of the neutralizing effect of activism on the high agency costs of free cash flow and on the information asymmetries of the market.

BackgroundScientific literature on posttraumatic growth after terrorist attacks has primarily focused on persons who had not been directly exposed to terrorist attacks or persons who had been directly exposed to them, but who were assessed few months or years after the attacks.MethodsWe examined long-term PTG in 210 adults directly exposed to terrorist attacks in Spain a mean of 29.6 years after the attacks. The participants had been injured by a terrorist attack or were first-degree relatives of people who had been (...) killed or injured by a terrorist attack. They completed diagnostic measures of emotional disorders and measures of PTSD and depression symptomatology, optimism, and PTG.ResultsMultiple regression analyses revealed gender differences and a positive linear relationship between PTG and cumulative trauma after the terrorist attack. Some PTG dimensions were significantly associated with PTSD symptomatology, these associations being linear, not curvilinear. However, PTG was not associated with depression symptomatology, diagnosis of emotional disorders, age, elapsed time since the attack, or optimism. In comparison with survivors assessed 18 years after the 1995 Oklahoma City bombing, Spanish victims of terrorism showed higher levels of appreciation of life, but lower levels of relating to others and spiritual change.ConclusionThe findings underscore the influence of gender on PTG and provide support to the hypothesis that some emotional distress may be a necessary condition of PTG. Future studies on PTG after terrorist attacks should take into consideration the characteristics of the terrorist attack itself and the contexts of violence and threat in which it occurred. The political, social, and cultural characteristics of the community affected by it and the profile and characteristics of other traumatic events suffered after the attack should also be taken into account in further research.

After compulsory secondary education; many teenagers face the process of choosing a university degree. This process involves uncertainties referred to their personal abilities, interests, social expectations and professional future. The present work is aimed at determining whether the reasons behind the selection of a particular university degree differ depending on the chosen degree. Another objective is determining whether these reasons differ significantly according to gender. The sample comprises 983 students belonging to the area of social and legal sciences at the (...) University of Seville. The obtained results reveal the existence of four main reasons behind the selection of university degrees for which significant gender-related differences were observed: easy degree, job opportunities, high wages and provision of social services. Besides, these seven reasons are observed to differ widely in six of the considered degrees. (shrink)

Avoiding whinges from various and potentially conflicting stakeholders is a major challenge for sustainable development and for the identification of sustainability scenarios or policies for biodiversity and ecosystem services. It turns out that independently complying with whinge thresholds and constraints of these stakeholders is not sufficient because dynamic ecological-economic interactions and uncertainties occur. Thus more demanding no whinge standards are needed. In this paper, we first argue that these new boundaries can be endogenously exhibited with the mathematical concepts of viability (...) kernel and viable controls. Second, it is shown how these no whinge kernels have components, such as harvesting of resources, that should remain within safe corridor while some other components, in particular biodiversity, have only lower conservation limits. Thus, using radar charts, we show how this no whinge kernels can take the shape of a tree that we name viability tree. These trees of viability capture the idea that the unbounded renewal potential of biodiversity combined with a bounded use of the different ecosystem services are crucial ingredients for the sustainability of socio-ecosystems and the design of no whinge policies reconciling the different stakeholders involved.

We present PhrasIS, a benchmark dataset composed of natural occurring Phrase pairs with Inference and Similarity annotations for the evaluation of semantic representations. The described dataset fills the gap between word and sentence-level datasets, allowing to evaluate compositional models at a finer granularity than sentences. Contrary to other datasets, the phrase pairs are extracted from naturally occurring text in image captions and news headlines. All the text fragments have been annotated by experts following a rigorous process also described in the (...) manuscript achieving high inter annotator agreement. In this work we analyse the dataset, showing the relation between inference labels and similarity scores. With 10K phrase pairs split in development and test, the dataset is an excellent benchmark for testing meaning representation systems. (shrink)

A new characterization of tabularity in tense logic is established, namely, a tense logic L is tabular if and only if $\mathsf {tab}_n^T\in L$ for some $n\geq 1$. Two characterization theorems for the Post-completeness in tabular tense logics are given. Furthermore, a characterization of the Post-completeness in the lattice of all tense logics is established. Post numbers of some tense logics are shown.

When people engage in conversation, they tailor their utterances to their conversational partners, whether these partners are other humans or computational systems. This tailoring, or adaptation to the partner takes place in all facets of human language use, and is based on a mental model or a user model of the conversational partner. Such adaptation has been shown to improve listeners' comprehension, their satisfaction with an interactive system, the efficiency with which they execute conversational tasks, and the likelihood of achieving (...) higher level goals such as changing the listener's beliefs and attitudes. We focus on one aspect of adaptation, namely the tailoring of the content of dialogue system utterances for the higher level processes of persuasion, argumentation and advice-giving. Our hypothesis is that algorithms that adapt content for these processes, according to a user model, will improve the usability, efficiency, and effectiveness of dialogue systems. We describe a multimodal dialogue system and algorithms for adaptive content selection based on multi-attribute decision theory. We demonstrate experimentally the improved efficacy of system responses through the use of user models to both tailor the content of system utterances and to manipulate their conciseness. (shrink)

Esta obra está organizada en tres partes, en las que se indaga la plausibilidad del discurso de la Bioética y Teológica. En la primera de ellas, se estudia el vínculo que existe entre esta disciplina científica, el mensaje evangélico y la tradición cristiana, punto de partida y origen de todo este entramado bioético que aspira a sal-vaguardar valores humanos fundamentales. En la segunda, se trata de la relación que debe regir entre esta rama de la Teología y el polifacético mundo (...) científico (biomedicina, bioderecho, etc.). Por su parte, en la tercera, se analiza el estatuto epistemológico que configura a la Bioética Teológica, es decir, sus señas de identi-dad; asimismo, en esta sección, se indaga igualmente acerca del papel que, por derecho propio, corresponde en la vida pública a esta disciplina científica.

The vast majority of contributions to the literature on spirituality in nursing make extravagant claims about transcendence, eternity, the numinous, higher powers, higher levels of existence, invisible forces, cosmic unity, the essence of humanity, or other supernatural concepts. Typically, these assertions are made without the support of argument or evidence; and, as a consequence, alternative ways of theorizing ‘spirituality’ have been closed off, while the lack of consistent scholarship has turned the topic into a metaphysical backwater. In this paper, I (...) adopt a different premise, rejecting unsupported claims, and surveying the ‘spirituality’ terrain from a naturalistic and reductionist perspective. I argue that, if we rid ourselves of non‐naturalistic assumptions, we will discover theoretical and clinical resources in health psychology, social psychology, neuropsychology, and pharmacopsychology – resources which confirm that it is possible to conceptualize the study of existential concerns, and how health professionals might respond to them, in a properly scientific manner. In order to illustrate the potential usefulness of these resources, I will take palliative care as an example. (shrink)

Positive changes or transformations have been the subject of study within spiritual traditions as well as humanistic and transpersonal psychology. The aim of the current study is to understand the process of transformation among Moslems in Indonesia, who follow spiritual practices, to achieve the nafs al-muṭma ínnah [tranquil self]. Ten participants in Yogyakarta province were involved in this study. They were recruited using nafs al-muṭmaʾinnah scale developed by the authors. In-depth interviews of both the participants and their significant others were (...) conducted. To analyse the data, an interpretative phenomenological analysis was employed. Five themes emerged from the data, including deviation from the basis of religious environment, spiritual discipline, transformative experiences, new characters and a continuous process. We conclude that participants experience spiritual-religious transformation and achieve the state of nafs al-muṭma ínnah [tranquil self]. The process of transformation occurs gradually after a sudden experience, and it continuously happens throughout the course of life. Three factors contribute to the transformation, including the role of predisposition, the role of a spiritual guide and the role of spiritual experiences.Contribution: As the study of spiritual-religious transformation is mainly conducted within a Judea-Christian tradition, this study significantly contributes to the literature by providing spiritual-religious transformation from an Islamic-Sufi perspective.

Psychological research has shown that cognitive illusions, of which visual illusions are just a special case, are systematic and pervasive, raising epistemological questions about how error in all forms of research can be identified and eliminated. The quantitative sciences make use of statistical techniques for this purpose, but it is not clear what the qualitative equivalent is, particularly in view of widespread scepticism about validity and objectivity. I argue that, in the light of cognitive psychology, the ‘error question’ cannot be (...) dismissed as a positivist obsession, and that the concepts of truth and objectivity are unavoidable. However, they constitute only a ‘minimal realism’, which does not necessarily bring a commitment to ‘absolute’ truth, certainty, correspondence, causation, reductionism, or universal laws in its wake. The assumption that it does reflects a misreading of positivism and, ironically, precipitates a ‘crisis of legitimation and representation’, as described by constructivist authors. (shrink)

Two major functions of the visual system are discussed and contrasted. One function of vision is the creation of an internal model or percept of the external world. Most research in object perception has concentrated on this aspect of vision. Vision also guides the control of object-directed action. In the latter case, vision directs our actions with respect to the world by transforming visual inputs into appropriate motor outputs. We argue that separate, but interactive, visual systems have evolved for the (...) perception of objects on the one hand and the control of actions directed at those objects on the other. This 'duplex' approach to high-level vision suggests that Marrian or 'reconstructive' approaches and Gibsonian or 'purposive-animate-behaviorist' approaches need not be seen as mutually exclusive, but rather as complementary in their emphases on different aspects of visual function.

This text explores how human beings construe experience: experience as a resource, as a potential for understanding, representing and acting on reality.

R. K. Elliott once commended R. S. Peters' work in philosophy of education for being an authentic expression of the self. Many philosophers, probably including Peters, might see this more as a weakness. In an attempt to resolve this difference various kinds of continuity between philosopher and philosophy are explored. These point to an ideal of a two-way, and ultimately ‘organic’, relationship whereby the philosophy expresses the self and the self is formed by the philosophy. Ways of teaching to favour (...) the development of such authenticity in novice philosophers are discussed. (shrink)

This book analyzes for the first time in English the ethical theory that underpins Qur’anic legislation by providing a classification of specific verses in which Islam’s holy book discusses moral issues. The principal purpose of this book is to demonstrate the ways in which the Qur’an theoretically and practically provides the moral code to which Muslims around the world adhere. The author divides his analysis into a survey of Qur’anic attitudes towards the basic ethical issues of obligation and responsibility, issues (...) of moral psychology such as motivation and intention, as well as matters of social ethics such as the function of law in society. He then explores the meanings of individual morality, morality within the family and civil society, and the relationship of morality to the idea of the state. (shrink)

The idea of meaning plays, together with the notion of caring, a pivotal role in recent nursing theory, informing its approach to philosophy, research and practice. Unlike caring, however, it has received relatively little analytical attention – a fact that is surprising in view of the scepticism about meaning that is characteristic of much contemporary philosophy and social theory. This paper reviews the philosophical literature on meaning, highlighting sceptical currents in the Wittgensteinian corpus, neo‐behaviourism and poststructuralism. It also considers a (...) similar line of thought that has emerged in social theory, questioning the explanatory value of concepts such as ‘practice’, ‘culture’, ‘norms’, ‘tacit knowledge’, and ‘tradition’. All these perspectives suggest that there is something wrong with the common‐sense picture of a set of shared, implicit rules that account for our ability to understand and communicate; and they all point to an alternative picture which is naturalistic, materialist and causal, and which depicts ‘shared meaning’ as a rather mysterious quality, unable to explain the familiar regularities of verbal and nonverbal behaviour. In this picture, while the idea of meaning can be retained, it ceases to be something shared, and becomes something individual and idiosyncratic, a unique cluster of associations, concomitants, and other habits of thought. The paper closes with a brief interpretation of what the alternative implies for a research methodology in nursing. In particular, it proposes that certain well established approaches will have to be abandoned, and that qualitative strategies will have to be grounded in a rigorous scientific framework, rather than in techniques (such as phenomenology), which presuppose a misleading and inaccurate conception of what meaning is.

Despite its uniform appearance, the cerebellar cortex is highly heterogeneous in terms of structure, genetics and physiology. Purkinje cells (PCs), the principal and sole output neurons of the cerebellar cortex, can be categorized into multiple populations that differentially express molecular markers and display distinctive physiological features. Such features include action potential rate, but also their propensity for synaptic and intrinsic plasticity. However, the precise molecular and genetic factors that correlate with the differential physiological properties of PCs remain elusive. In this (...) article, we provide a detailed overview of the cellular mechanisms that regulate PC activity and plasticity. We further perform a pathway analysis to highlight how molecular characteristics of specific PC populations may influence their physiology and plasticity mechanisms. (shrink)
