Characterizing neuromorphologic alterations with additive shape functionals

The complexity of a neuronal cell shape is known to be related to its function. Specifically, among other indicators, a decreased complexity in the dendritic trees of cortical pyramidal neurons has been associated with mental retardation. In this paper we develop a procedure to address the characterization of morphological changes induced in cultured neurons by over-expressing a gene involved in mental retardation. Measures associated with the multiscale connectivity, an additive image functional, are found to give a reasonable separation criterion between two categories of cells. One category consists of a control group and two transfected groups of neurons, and the other, a class of cat ganglionary cells. The reported framework also identified a trend towards lower complexity in one of the transfected groups. Such results establish the suggested measures as an effective descriptors of cell shape

Food conveying masculinities: how conformity to hegemonic masculinity norms influences food consumption

This study investigated how conformity to hegemonic masculinity norms affects men’s and women’s food consumption and whether such influence was contextually modulated. A total of 519 individuals (65% women; M = 44 years old) participated in a 2 (gender salience: low vs high) × 2 (participants’ sex: male vs female) quasi-experimental between-subjects design, completing the Conformity to Masculinity Norms Inventory (Portuguese version) and reporting their past week’s food consumption. Gender salience moderated the relation between men’s conformity to masculinity norms and food consumption; sex-related differences in food consumption were partially mediated by conformity to masculinity norms. Implications for food consumption interventions are discussed.info:eu-repo/semantics/acceptedVersio

Older adults’ preferences for formal social support of autonomy and dependence in pain: development and validation of a scale

Chronic pain among older adults is common and often disabling. Pain-related formal social support (e.g., provided by staff at day-care centres, nursing homes), and the extent to which it promotes functional autonomy or dependence, plays a significant role in the promotion of older adults’ ability to engage in their daily activities. Assessing older adults’ preferences for pain-related social support for functional autonomy or dependence could contribute to increase formal social support responsiveness to individuals’ needs. Therefore, this study aimed at developing and validating the Preferences for Formal Social Support of Autonomy and Dependence in pain Inventory (PFSSADI). One hundred and sixty five older adults with chronic musculoskeletal pain (Mage=79.1, 67.3% women), attending day-care centers, completed the PFSSADI, the revised Formal Social Support for Autonomy and Dependence in Pain Inventory, and a measure of desire for (in)dependence; the PFSSADI was filled out again 6 weeks later. Confirmatory factor analyses showed a structure of two correlated factors (r= .56): (a) Preferences for Autonomy Support (?=.99); and (b) Preferences for Dependence Support (?=.98). The scale showed good test-retest reliability, sensitivity and discriminant and concurrent validity; the higher the preferences for dependence support the higher the desire for dependence (r=.33) and the lower the desire for independence (r=-.41). The PFSSADI is an innovative tool, which may contribute to explore the role of pain-related social support responsiveness on the promotion of older adults’ functional autonomy when in pain.info:eu-repo/semantics/acceptedVersio

Medida de desumanização baseada em traços: adaptação para a população Portuguesa

Although dehumanization (i.e., the denial of full humanness to others; Haslam, 2006) has been a frequent subject in social psychology, a set of traits designed to evaluate this phenomenon has not been validated to the Portuguese population. The main purpose of this study was to translate, culturally adapt and validate a set of dehumanization traits proposed by Haslam and colleagues (Haslam & Bain, 2007; Haslam, Bain, Douge, Lee & Bastian, 2005), which measure both the denial of uniquely human and human nature traits. A sample of 597 individuals (Mage = 40.83; SD = 11.50) were asked to rate a set of 52 traits on how much they perceived each as a characteristic of human nature and human uniqueness, as well as its desirability. T-tests were conducted to distinguish between low and high rated traits in each dimension, and to construct clusters of traits that differ in each dimension. We successfully provide a measure containing positive traits in both senses of humanness dimensions; however, we were only able to validate a human uniqueness measure with negative valence. Implications of this measure for future research on dehumanization processes are discussed.info:eu-repo/semantics/publishedVersio

Late pleistocene carnivores (Carnivora: Mammalia) from a cave sedimentary deposit in northern Brazil

The Brazilian Quaternary terrestrial Carnivora are represented by the following families: Canidae, Felidae, Ursidae, Procyonidae Mephitidae and Mustelidae. Their recent evolutionary history in South America is associated with the uplift of the Panamanian Isthmus, and which enabled the Great American Biotic Interchange (GABI). Here we present new fossil records of Carnivora found in a cave in Aurora do Tocantins, Tocantins, northern Brazil. A stratigraphical controlled collection in the sedimentary deposit of the studied cave revealed a fossiliferous level where the following Carnivora taxa were present: Panthera onca, Leopardus sp., Galictis cuja, Procyon cancrivorus, Nasua nasua and Arctotherium wingei. Dating by Electron Spinning Resonance indicates that this assemblage was deposited during the Last Glacial Maximum (LGM), at least, 22.000 YBP. The weasel, G. cuja, is currently reported much further south than the record presented here. This may suggest that the environment around the cave was relatively drier during the LGM, with more open vegetation, and more moderate temperatures than the current Brazilian Cerrado.Facultad de Ciencias Naturales y Muse

The revised formal social support for autonomy and dependence in pain inventory (FSSADI_PAIN): confirmatory factor analysis and validity

ain among older adults is common and generally associated with high levels of functional disability. Despite its important role in elders' pain experiences, perceived (formal) social support (PSS) has shown inconsistent effects on their functional autonomy. This suggests a moderator role of 2 recently conceptualized functions of PSS: perceived promotion of dependence versus autonomy. The present study aimed at revising and further validating the Formal Social Support for Autonomy and Dependence in Pain Inventory (FSSADI_PAIN), which measures these 2 PSS functions among institutionalized elders in pain. Two hundred fifty older adults (mean age = 81.36 years, 75.2% women) completed the revised FSSADI_PAIN along with measures of physical functioning (ie, Medical Outcome Study Short Form-36) and informal PSS (ie, Social Support Scale of Medical Outcomes Study). Confirmatory factor analyses showed a good fit for a 2-factor structure: 1) perceived promotion of autonomy (n = 4 items; alpha = .89), and 2) perceived promotion of dependence (n = 4 items; alpha = .85). The revised FSSADI_PAIN showed good content, discriminant, and criterion-related validity; it discriminated the PSS of male and female older adults and also of elders with different levels of physical functioning. In conclusion, the revised FSSADI_PAIN is an innovative, valid, and reliable tool that allows us to assess 2 important functions of PSS, which may play a relevant role in the prevention and reduction of pain-related physical disability and functional dependence among institutionalized older adults. Perspective: This article presents a revised version of the FSSADI_PAIN that assesses elders' perceived promotion of functional autonomy/dependence as 2 independent functions of perceived social support. This measure may contribute to future research on the role of close interpersonal contexts on the promotion of active aging among elders with chronic pain.info:eu-repo/semantics/acceptedVersio

Helping your partner with chronic pain: the importance of helping motivation, received social support, and its timeliness

Objective Like all intentional acts, social support provision varies with respect to its underlying motives. Greater autonomous or volitional motives (e.g., enjoyment, full commitment) to help individuals with chronic pain (ICPs) are associated with greater well-being benefits for the latter, as indexed by improved satisfaction of their psychological needs for autonomy, competence, and relatedness. The present study investigates the processes explaining why partners’ autonomous or volitional helping motivation yields these benefits. Methods A total of 134 couples, where at least one partner had chronic pain, completed a 14-day diary. Partners reported on their daily helping motives, whereas ICPs reported on their daily received support, timing of help, need-based experiences, and pain. Results On days when partners provided help for volitional motives, ICPs indicated receiving more help, which partially accounted for the effect of autonomous helping motivation on ICP need-based experiences. Timing of help moderated the effects of daily received support on ICP need-based experiences. Conclusions Findings highlight the importance of ICPs of receiving support in general and the role of timing in particular, which especially matters when there is little support being received.info:eu-repo/semantics/acceptedVersio

The SIforAGE project: social innovation for active and healthy ageing

This article describes the SIforAGE Project – an innovative approach to an aged Europe. The SIforAGE consortium is integrated by a wide range of stakeholders working together in order to promote an active and healthy ageing. ISCTE-IUL is one of the partners involved in this project and has been developing an important role in different work packages: (i ) Technology Experience cafés aiming to involve older people in the development of technological devices addressed to them (which had a general positive impact regarding the attitudes and intentions of older participants to use technologies); (ii ) conceptualization and development of an intervention program (imAGES) to fight ageism among children (the pilot program developed in Lisbon revealed the efficacy of this program); (iii ) analysis of the anti-age discrimination laws (AADL’s) in five European countries (these laws are present in the European countries analyzed but it was identified a gap between legislation and its compliance); (iv) organization of a call for prize on social innovation research on the ageing field (which was widely disseminated across several European countries). Through these several activities, the SIforAGE project constitutes a step forward towards the development of a more inclusive society, a society for all «ages».info:eu-repo/semantics/acceptedVersio
