Evolutionary diversification in Central Brazil: where Amazonia and Cerrado meet

Apesar da fauna de mamíferos Neotropicais ser uma das mais ricas do mundo, o nosso conhecimento sobre os limites de espécies, distribuições geográficas e relações filogenéticas está ainda agora no seu início. As áreas de transição entre os dois maiores biomas da América do Sul, o Cerrado e a Amazónia, são ainda menos conhecidas. Até ao momento, escassos estudos focaram os pequenos mamíferos destas áreas. Destes estudos, apenas dois apresentam dados taxonómicos e de distribuição geográfica de uma lista de espécies reduzida e, nenhum é focado nos processos evolutivos que conduziram à diversidade destas áreas. O presente trabalho tem como objectivo aumentar o conhecimento básico sobre a diversidade do médio Rio Araguaia, na região central do Brasil, através da amostragem e análise de espécies de pequenos mamíferos, integrando um intenso trabalho de campo, de laboratório e de museu. Desta forma, um total de 22 espécies é registado para o médio Araguaia. De entre estas espécies, descreve-se uma espécie nova de Rhipidomys, regista-se uma espécie não descrita de Thrichomys e uma potencial nova forma de Oligoryzomys, e também se apresenta uma diagnose emendada do obscuro Oecomys cleberi. Para cada espécie, são também descritas as suas características morfológicas e resumem-se os seus aspectos de distribuição geográfica e história natural. Para os quatro géneros acima referidos, são apresentadas as análises filogenéticas que permitem a identificação das espécies. Adicionalmente, os princípios da filogeografia são aplicados para estudar os padrões da distribuição geográfica da diversidade genética de três roedores sigmodontíneos e seis marsupiais didelphídeos. Os resultados obtidos demonstram que o Rio Araguaia forma uma barreira geográfica para espécies especialistas em florestas não-alagáveis; por outro lado, espécies generalistas apresentam partilha de haplótipos em ambas as margens do rio. Argumentamos também que os refúgios florestais e os gradientes poderão ter tido um papel importante para moldar a estrutura genética de populações de pequenos mamíferos no Brasil central. Em suma, os resultados apresentados corroboram a proposição de que a diversidade Neotropical não poderá ser explicada através de um único modelo de especiação e que estes não são mutuamente exclusivos. O entendimento integral dos processos ecológicos e históricos que deram origem à fauna Neotropical, assim como a continuidade de estudos sistemáticos, depende da realização de novas amostragens e consequente enriquecimento dos museus com colecções apropriadas.

Second Wave Positive Psychology: Exploring the Positive–Negative Dialectics of Wellbeing

Positive psychology has tended to be defined in terms of a concern with ‘positive’ psychological qualities and states. However, critics of the field have highlighted various problems inherent in classifying phenomena as either ‘positive’ or ‘negative.’ For instance, ostensibly positive qualities (e.g., optimism) can sometimes be detrimental to wellbeing, whereas apparently negative processes (like anxiety) may at times be conducive to it. As such, over recent years, a more nuanced ‘second wave’ of positive psychology has been germinating, which explores the philosophical and conceptual complexities of the very idea of the ‘positive.’ The current paper introduces this emergent second wave by examining the ways in which the field is developing a more subtle understanding of the ‘dialectical’ nature of flourishing (i.e., involving a complex and dynamic interplay of positive and negative experiences). The paper does so by problematizing the notions of positive and negative through seven case studies, including five salient dichotomies (such as optimism versus pessimism) and two complex processes (posttraumatic growth and love). These case studies serve to highlight the type of critical, dialectical thinking that characterises this second wave, thereby outlining the contours of the evolving field.

Flourishing as a dialectical balance: emerging insights from second-wave positive psychology

Positive psychology, an emergent branch of scholarship concerned with wellbeing and flourishing, initially defined itself by a focus on “positive” emotions and qualities. However, critics soon pointed out that this binary logic—classifying phenomena as either positive or negative, and valorising the former while disparaging the latter—could be problematic. For example, apparently positive qualities can be harmful to wellbeing in certain circumstances, while ostensibly dysphoric emotional states may on occasion promote flourishing. Responding to these criticisms, over recent years a more nuanced “second wave” of positive psychology has been developing, in which wellbeing is recognized as involving a dialectical balance of light and dark aspects of life. This article introduces this emergent second wave, arguing that it is characterized by four dialectical principles. First, the principle of appraisal states that it is difficult to categorically identify phenomena as either positive or negative, since such appraisals are fundamentally contextually dependent. Second, the principle of co-valence holds that many states and qualities at the heart of flourishing, such as love, are actually a complex blend of light and dark elements. Third, the principle of complementarity posits that not only are such phenomena co-valenced, but that their dichotomous elements are in fact co-creating, two intertwined sides of the same coin. Finally, the principle of evolution allows us to understand second-wave positive psychology as itself being an example of a dialectical process. This article is published as part of a collection entitled “On balance: lifestyle, mental health and wellbeing”.

The Influence of Causal Explanations and Diagnostic Labeling on Psychology Students’ Beliefs About Treatments, Prognosis, Dangerousness and Unpredictability in Schizophrenia

This study explored views of 566 Italian psychology students about schizophrenia. The most frequently cited causes were psychological traumas (68%) and heredity (54%). Thirty-three percent of students firmly believed that people with the condition could recover. Reporting heredity among the causes, and identifying schizophrenia were both associated with prognostic pessimism, greater confidence in pharmacological treatments and lower confidence in psychological treatments. Schizophrenia labeling was also associated with higher perception of unpredictability and dangerousness. Compared to first year students, fourth/fifth year students more frequently reported heredity among the causes, and were more pessimistic about schizophrenia recovery. Stigma topics should be included in future psychologists’ education.

Fuzzy model identification by evolutionary, gradient based and memtic algorithms

One of the crucial problems of fuzzy rule modeling is how to find an optimal or at least a quasi-optimal rule base fro a certain system. In most applications there is no human expert available, or, the result of a human expert's decision is too much subjective and is not reproducible, thus some automatic method to determine the fuzzy rule base must be deployed.

Design of neuro-fuzzy models by evolutionary and gradient-based algorithms

All systems found in nature exhibit, with different degrees, a nonlinear behavior. To emulate this behavior, classical systems identification techniques use, typically, linear models, for mathematical simplicity. Models inspired by biological principles (artificial neural networks) and linguistically motivated (fuzzy systems), due to their universal approximation property, are becoming alternatives to classical mathematical models. In systems identification, the design of this type of models is an iterative process, requiring, among other steps, the need to identify the model structure, as well as the estimation of the model parameters. This thesis addresses the applicability of gradient-basis algorithms for the parameter estimation phase, and the use of evolutionary algorithms for model structure selection, for the design of neuro-fuzzy systems, i.e., models that offer the transparency property found in fuzzy systems, but use, for their design, algorithms introduced in the context of neural networks. A new methodology, based on the minimization of the integral of the error, and exploiting the parameter separability property typically found in neuro-fuzzy systems, is proposed for parameter estimation. A recent evolutionary technique (bacterial algorithms), based on the natural phenomenon of microbial evolution, is combined with genetic programming, and the resulting algorithm, bacterial programming, advocated for structure determination. Different versions of this evolutionary technique are combined with gradient-based algorithms, solving problems found in fuzzy and neuro-fuzzy design, namely incorporation of a-priori knowledge, gradient algorithms initialization and model complexity reduction.

Dynamics and dilemmas in social psychology: social relations, identities and cognition

This paper aims to provide a systematised overview of the paradigmatic orientations in social psychology in Portugal by identifying the most cited publications. Results show that the eight most cited thematic are: (1) deviance and reactions to deviance, (2) methodology, (3) prejudice and discrimination, (4) gender studies, (5) risk, environment and safety, (6) information processing, social judgment, familiarity and mood, (7) social representations and (8) social justice and belief in a just world. These eight most salient thematics can be sorted into three current paradigmatic orientations in contemporary social psychology: (a) social cognition; (b) the study of collective beliefs, ideologies and social representations; and (c) the study of identity and its impact on intra- and intergroup processes. The paper finishes with a reflection on the future developments of the discipline and the dilemmas that social psychology in Portugal could face.

Enhancing Student Learning Experiences in Sport Psychology Modules Using Practical Activities

The University of Worcester states in its most recent strategic plan (2013 – 2018) a set of enduring values that guide and direct the activities of the institution. The first listed, and perhaps the most important value is the striving to be “an outstanding university at which to be a student”. This is further supplemented by values such as “to inspire our students to reach their full potential through excellent, innovative teaching, scholarship and research” (University of Worcester 2013: p.4). One of the many ways in which the institution strives to provide this outstanding educational experience is through regular engagement, both formal and informal, with students at a number of points in each semester. Regular experiences of collating formal and informal feedback has led to the identification of a common theme amongst Higher National Diploma (HND) students in the Institute of Sport and Exercise Sciences (ISES), where they consistently request ‘more practicals’. The ISES modules however are designed to incorporate a high degree of interaction, practical activities and tasks. This is especially important for those studying at HND level as research suggests differences in learning preferences exist when compared to undergraduate students, the former preferring a more tactile style of learning (Peters et al. 2008). Using an introductory Sport Psychology HND module as an example, practical activities and tasks are fully embedded in the taught sessions to enable contextual links to be made between the learning outcomes and their subsequent use. Examples of these include: a. interviewing athletes to produce a performance profile (Butler & Hardy 1992); b. completing psychometric instruments such as the Competitive State Anxiety Inventory-2 (CSAI-2) to measure competitive anxiety in sport (Martens et al. 1990) and demonstrate data collection and construct measurement; c. performing relaxation interventions on the students to demonstrate how specific techniques (in this instance, decreasing somatic anxiety) might work in practice; d. demonstrating how observational learning facilitates skill acquisition by creating experimental conditions that the students participate in, in teaching a new skill. Nevertheless owing to the students' previously stated on-going requests for more practical activities, it became evident that assumptions about what students consider an effective means of experiential or active learning in the context of sport-related disciplines of study needed to be investigated. This is where the opportunity to undertake an action research project arose, this being a practical method commonly employed in pedagogical enquiry to aid reflection on teaching and assessment practice for the purposes of working towards continuous improvement.

Bridging the Divide in Work and Occupational Psychology: Evidence From Practice

This study explores the extent to which work and organizational (W&O) psychology practitioners use evidence, how they apply it to the everyday contexts in which they work and the types of barriers they encounter in so doing. It adopts a mixed methods approach involving the administration of a survey to a UK sample (N=163) of W&O psychologists and a series of semi-structured interviews (N=25) exploring in greater depth how evidence is applied in practice. Findings reveal that practitioners consult a wide range of different types of evidence which they employ at various stages of engagement with client organisations and that this evidence is pressed into service in the pursuit of solutions which are both acceptable from the client perspective and consistent with the scientific standards underpinning professional knowledge and expertise in W&O psychology. Barriers to evidence-use were mainly practical in nature, concerning issues around managing the client-consultant relationship and the particularities of implementation context, both of which were shown to influence evidence utilisation. The study contributes to current debate on the extent to which W&O psychologists adopt an evidence-based approach and provides a valuable and much called-for empirical insight into the enactment of the scientist-practitioner model in W&O psychology

Counselling Psychology in the United Kingdom

Counselling psychology within the UK has grown over the last three decades, adapting to many changes in the field of applied psychology, whilst remaining true to its core values and humanistic origins. The identity of counselling psychology is strongly rooted in a relational stance and applied psychology, where attention to psychological formulation is given to improve psychological functioning and well-being. This article outlines a brief history of counselling psychology in the UK, the training process, credentialing and looks at some important challenges and future directions for counselling psychology in the UK. A proportion of the members from the British Psychological Society’s division of counselling psychology (DCoP, N = 148) took part in the study. Participants provided demographic, training, employment, workplace and career pathway information obtained through an online questionnaire distributed to all DCoP members. On the whole, DCoP members are working in a variety of areas within the UK and the findings of this article contribute to the international study comparing counselling psychology across the globe.

Investigating Behaviour and Face Encoding in a Hypothetical Real-World Social Contract: Handwashing in Hazardous Health Settings

Investigations into the evolutionary origins of human cognition has shown that individuals’ memory for others is influenced by the latter’s behaviour in social contracts. Such research is primarily based on hypothetical or more abstract forms of social contracts, whereas an application of this knowledge to everyday health behaviours can be of great value. To address this, the current study investigated whether participants who were asked to imagine themselves in a hypothetical hazardous health scenario showed differential response sensitivity (d’) and latency (RT) to faces of hospital staff tagged with contrasting hand hygiene before touching patients: clean hands, dirty hands, or unknown hand-washing behaviour (control). The test used a two alternative forced-choice (2AFC: “old/new”) face recognition paradigm. The findings showed that d’ to dirty and clean hands was similar, but higher than for controls. Moreover, d’ was not affected by the occupation of hospital staff (nurses vs porters). The absence of memory gains towards clean or dirty hands points to the need for new strategies to remind patients to observe (and remember) the hand hygiene of others when exposed to hazardous health environments.
