A Comprehensive Decision Approach for Rubber Tree Planting Management in Africa

The main objective of this study is to settle a rigorous field of decision analysis for rubber tree clones selection. Nowadays, there does not exist any process based upon a rigorous method to select the best clone to be plant in order to get the highest return on investment. The only known selection method is to use the experience of different protagonists acting in the plantation. So, we need a tool that takes into account very important criteria in order to achieve the main objective. This goal is achieved by using multicriterion analysis methods to the clone selection. The ranking procedure uses Elimination and Choice Expressing the Reality (ELECTRE III). For each criterion, indifference and preference thresholds are determined after establishing the relative importance of each criterion including rubber tapping, cumulative production during 15 years, cumulative production between 15 and 25 years, wind resistance, disease resistance, physiological resistance, grafting and quality of the rubber.

Emotional reactions to scandals: When does moral character make a difference?

A scandal can evoke public outrage when it is widely publicized and involves an individual who is perceived to have a high level of cultural representativeness. Two experiments showed that when the scandalous target's moral character was highlighted, emotional responses towards the target were least negative when the scandal was widely circulated and when the target was seen as a representative of his culture. These results suggest that when a cultural symbol is implicated in a widely‐circulated scandal, the negative emotions directed towards the scandalous individual can be alleviated when the public remains confident in his or her commitment to morality.     

Early development of gaze following into distant space in juvenile Greylag geese (Anser anser)

Visual co-orientation with another's gaze direction (gaze following) may provide important information about the location of food, social interactions or predators. Gaze following has been shown in a variety of mammals, but only in few bird species, and has not been tested in precocial birds at all. It has been suggested that gaze following is an anti-predator behaviour, and in Common ravens (Corvus corax) and rooks (C. frugilegus), it emerges shortly after fledging, at a time when young birds leave the predator-safe nest. However, if gaze following is adaptive, the developmental pattern should differ between altricial and precocial birds. Greylag geese (Anser anser) are highly social birds with a precocial development. Goslings move and feed independently within 24 h post-hatching, and they are highly vulnerable to aerial predators. We therefore predicted that greylag geese are capable of gaze following and that they develop this skill already pre-fledging. We experimentally tested 19 hand-raised greylag goslings for their ability to follow a conspecific's gaze when they were between 10 days and 6 weeks old. In line with our predictions, first responses were already detectable in 10-day-old goslings. Our results therefore not only demonstrate that greylag geese follow the gaze of conspecifics into distant space, but that they also develop this ability much earlier than altricial birds.     

Awakening: Career Opportunities After the Storm

Immediately following natural disasters, basic needs are provided; however, the long‐term needs of individuals are neglected. The narrative approach (Brott, 2001; Cochran, 1997) to career counseling is offered as a method to assist survivors of natural disasters to tell their story and create new meaning related to their career paths.     

Why do they exercise less? Barriers to exercise in high-anxiety-sensitive women

Anxiety sensitivity (AS; fear of arousal sensations) is a risk factor for mental and physical health problems, including physical inactivity. Because of the many mental and physical health benefits of exercise, it is important to better understand why high-AS individuals may be less likely to exercise. The present study's aim was to understand the role of barriers to exercise in explaining lower levels of physical exercise in high-AS individuals. Participants were undergraduate women who were selected as high (n = 82) or low (n = 72) AS. High-AS women participated in less physical exercise and perceived themselves as less fit than low-AS women. Mediation analyses revealed that barriers to exercise accounted for the inverse relationships between AS group and physical exercise/fitness levels. Findings suggest that efforts to increase physical exercise in at-risk populations, such as high-AS individuals, should not focus exclusively on benefits to exercise but should also target reasons why these individuals are exercising less.     

Embodied Cultural Cognition: Situating the Study of Embodied Cognition in Socio‐Cultural Contexts

Embodiment research has demonstrated that cognition is grounded in bodily interactions with the environment and that abstract concepts are tied to the body’s sensory and motor systems. Building upon this embodiment perspective and advancing our understanding, we discuss the extension of embodied cultural cognition. We propose that some associations between bodily experiences and abstract concepts are not randomly formed; rather, the development of such associations is situated in a socio‐cultural context, informed by cultural imperatives, values, and habits. We draw evidence supporting this view of embodied cultural cognition in body–mind linkages manifested in construal of emotions, time perception, person perception, social power, and moral reasoning. To further extend this research avenue that synthesizes the studies of embodied cognition and culture, we also suggest potential future research directions inspired by this view. This embodied cultural cognition account is useful in understanding and organizing accumulating discoveries of cultural variations in embodiments; it also highlights the social situatedness of embodied cognition and is, therefore, highly compatible with theorizing and research in social and cultural psychology.     

The role of encoding strategies in the verbal memory performance in patients with schizophrenia

Background. Verbal learning and memory is often compromised in patients with schizophrenia who prefer encoding words in order of their presentation (serial clustering) rather than using semantic categories (semantic clustering). Method. One hundred and four in‐patients with schizophrenia were assessed twice with the California Verbal Learning Test. Results. Patients showed significantly less semantic than serial clustering at both assessment times. Usage of encoding strategies were not stable over time. An increase in semantic clustering improved recall and recognition performance. Conclusions. Patients with schizophrenia should be taught to use the more effective encoding strategy of semantic clustering in order to improve their memory performance.     

Resilience: A Disability Studies and Community Psychology Approach

This paper contests traditional psychological understandings of resilience through reference to a research project exploring resilience in the lives of disabled people. The paper briefly historically locates individualistic accounts of resilience (which have often been unhelpful in the lives of disabled people) and then moves into more recent social constructionist theories of this phenomenon. This latter perspective necessarily locates resilience in a network of resources including material resources, relationships, identity, bodies and minds, power and control, community participation, community cohesion and social justice. We argue that the recognition of resilience as a relational product is important and in tune with attempts to make psychology less an individualistic encounter and more a community intervention. However, disabled people, their politics and the development of critical disability studies, contest and challenge normative ideas of what it means to live with a resilient network of resources. In this sense disability offers new and exciting ways of addressing resilience.     

Decoupling neural networks from reality: dissociative experiences in torture victims are reflected in abnormal brain waves in left frontal cortex

From a neuroscience perspective, little is known about the long-term effect of torture. Dissociative experiences and posttraumatic stress disorder are often the results of this experience. We examined psychological dissociation within a group of 23 torture victims and report its manifestations within neural networks in the human brain. In particular, we observed that dissociative experiences are associated with slow abnormal brain waves generated in left ventrolateral frontal cortex. Given that focal slow waves often result from depriving neural networks of major input, the present results may indicate decoupling of frontal affective processors from left cortical language areas. This interpretation is consistent with the fact that disturbed access to structured verbal memory concerning traumatic events is a core feature of the dissociative experience.     

The characteristics of LTP induced in hippocampal slices are dependent on slice-recovery conditions

In area CA1 of hippocampal slices which are allowed to recover from slicing "in interface" and where recordings are carried out in interface, a single 1-sec train of 100-Hz stimulation triggers a short-lasting long-term potentiation (S-LTP), which lasts 1-2 h, whereas multiple 1-sec trains induce a long-lasting LTP (L-LTP), which lasts several hours. Moreover, the threshold and the features of these LTP depend on the history of the neurons, a phenomenon known as metaplasticity. Here, where all recordings were performed in interface, we found that allowing the slices to recover "in submersion" had dramatic metaplastic effects. In these conditions, a single 1-sec train at 100 Hz induced an L-LTP which lasted at least 4 h and was dependent on protein synthesis. Interestingly, this type of metaplasticity was observed when the concentration of Mg(++) used was 1.0 mM but not when it was 1.3 mM. The LTP induced by four 1-sec trains at 100 Hz was similar whatever the incubation method. However, the signaling cascades recruited to achieve that pattern were different. In the interface-interface paradigm (recovery and recording both in interface) the four-train induced LTP recruited the PKA signaling pathway but not that of the p42/44MAPK. On the contrary, in the submersion-interface paradigm the four-train induced LTP recruited the p42/44MAPK signaling pathway but not that of the PKA. To our knowledge this is the first example of metaplasticity involving the recruitment of signaling cascades in LTP.
