Single-Joint Movements in Parkinson's Disease: A Pulse-Width and Pulse-Height Theory Review

The process by which the brain controls single-joint movements (SJM) is still not well understood. Some studies have defined rules describing the duration and magnitude of the agonist and antagonist muscles. Therefore, the purpose of this study was to analyze scientific publications about the electromyographic characteristics of SJM performed by patients with Parkinson's disease. A bibliographical review of the years 1989–2015 was performed using keywords such as electromyography, upper limb, and Parkinson's disease. After applying the inclusion criteria, 8 articles were included for analysis. The literature indicates that despite the lack of studies, it is possible to assume that considering the SJM, those with Parkinson's disease only control the magnitude of electromyography activation, being consistent only with the pulse-height theory control.     

Psychometric Properties of the Objectified Body Consciousness Scale (OBCS) in Spanish Preadolescents

Sex Roles - Objectification theory postulates that the body is constructed as a sexual object and is subject to observation and evaluation in such a way that a person may feel that their body is an...     

Air pollution, cognitive deficits and brain abnormalities: a pilot study with children and dogs

Exposure to air pollution is associated with neuroinflammation in healthy children and dogs in Mexico City. Comparative studies were carried out in healthy children and young dogs similarly exposed to ambient pollution in Mexico City. Children from Mexico City (n: 55) and a low polluted city (n:18) underwent psychometric testing and brain magnetic resonance imaging MRI. Seven healthy young dogs with similar exposure to Mexico City air pollution had brain MRI, measurement of mRNA abundance of two inflammatory genes cyclooxygenase-2, and interleukin 1 beta in target brain areas, and histopathological evaluation of brain tissue. Children with no known risk factors for neurological or cognitive disorders residing in a polluted urban environment exhibited significant deficits in a combination of fluid and crystallized cognition tasks. Fifty-six percent of Mexico City children tested showed prefrontal white matter hyperintense lesions and similar lesions were observed in dogs (57%). Exposed dogs had frontal lesions with vascular subcortical pathology associated with neuroinflammation, enlarged Virchow-Robin spaces, gliosis, and ultrafine particulate matter deposition. Based on the MRI findings, the prefrontal cortex was a target anatomical region in Mexico City children and its damage could have contributed to their cognitive dysfunction. The present work presents a groundbreaking, interdisciplinary methodology for addressing relationships between environmental pollution, structural brain alterations by MRI, and cognitive deficits/delays in healthy children.     

An analysis of sustainable consumption practices through the role of the consumer behavior in the circular economy

Sustainable consumption analyses the choice of products to address environmental issues. In recent years, the circular economy model () has offered strategies as possible solutions to address the growing demand for action on climate justice. The success of a business model depends on understanding the consumer's role. The power of individual consumer actions is vital for minimizing the adverse impacts of climate change. Although the effectiveness of in the business sector has been studied, the literature has ignored the role of consumers in sustainable consumption practices through. Thus, using a survey technique, this quantitative study analyzed part of the theoretical model of Mostaghel and Chirumalla to analyze how awareness and consumer attitude significantly impact purchase intention and ethical purchasing behavior. The data analyzed through PLS-SEM reflected several theoretical implications in the forms of consumer behavior, a topic that has not been addressed in the literature.     

Effects of neonatal treatment with cyproterone acetate on aggressive behavior induced by footshock in adult male rats

High levels of androgens are required to organize aggressive behavior in adult male rats. Footshock-induced aggression was tested in Wistar rats allocated to one of three experimental groups: control (oil-injected) males (M), males neonatally injected with the antiandrogen cyproterone acetate (CA), and males treated as in the CA group but gonadectomized just before puberty (CAG). An antiaggressive effect of CA in those adult male rats neonatally treated with this compound was found. Neonatal exposure to cyproterone acetate exerts an antiandrogenic effect over the expression of shock-induced aggressive behavior. The behavioral effects of CA were not countered by adult treatment with testosterone propionate.     

Ego depletion in consumer behavior: A review,synthesis, and research agenda

This research aims to identify, analyze, and map the intellectual structure of the topic of ego depletion in consumer behavior through the bibliometric strategies of namely co-citation analysis and bibliographic coupling. We performed the co-citation analysis covering 20 years of research, divided into two 10-year analyses. The bibliographic coupling analysis focused on recent research covering the last decade, divided into two five-year analyses. The results presented the most important research, authors, research centers, and journals on the topic, as well as the factors derived from the co-citation and bibliographic coupling analysis, the evolution of the theme between the analysis and subsequent periods, and the agenda for future research. The main contribution of this article is the proposition of an agenda for future research on ego depletion and its effects on consumer behavior.     

A Pilot Study Addressing the Impact of Religious Practice on Quality of Life of Breast Cancer Patients During Chemotherapy

The aim of this preliminary study was to investigate whether religious practice can modify quality of life (QoL) in BC patients during chemotherapy. QoL and religion practice questionnaire (RPQ) scores were evaluated in a sample of BC patients in different moments. Before chemotherapy initiation, women with lower physical and social functional scores displayed higher RPQ scores. On the other hand, low RPQ patients worsened some QoL scores over time. Body image acceptance was positively correlated with religious practice and specifically praying activity. This preliminary study suggests the importance of religion in coping with cancer chemotherapy.     

Phenomenology and its Futures

Born in 1900–1901 with the publication of Edmund Husserl's Logical Investigations, phenomenology, as a critical method of reflection on consciousness and its cognitive achievements against its naturalisation in the natural sciences, has undergone many changes and developments. Critiques of both its methods and tasks have emerged, plus it has served as an inspiration for numerous thinkers, including Max Scheler, Martin Heidegger, Jean-Paul Sartre, Gabriel Marcel, Simone de Beauvoir, Maurice Merleau-Ponty, Jean-Luc Nancy, Michel Henry, Emmanuel Levinas, Hans-Georg Gadamer, Paul Ricoeur and Jacques Derrida, in their attempts to address the question of value, the meaning of being, existence, the lived body, the Other, life, art, history and language in original and fresh ways. The current paper reflects upon the question of what the fate of phenomenology in the twenty-first century could be by consider- ing some of the recent work presented at the first conference of the South African Centre for Phenomenology held at the University of Johannesburg earlier this year.     

Natural Disaster and Risk of Psychiatric Disorders in Puerto Rican Children

We examined the persistence of psychiatric disorders at approximately 18 and 30 months after a hurricane among a random sample of the child and adolescent population (4–17 years) of Puerto Rico. Data were obtained from caretaker-child dyads (N = 1,886) through in person interviews with primary caretakers (all children) and youth (11–17 years) using the Diagnostic Interview Schedule for Children IV in Spanish. Logistic regressions, controlling for sociodemographic variables, were used to study the relation between disaster exposure and internalizing, externalizing, or any disorder. Children’s disaster-related distress manifested as internalizing disorders, rather than as externalizing disorders at 18 months post-disaster. At 30 months, there was no longer a significant difference in rates of disorder between hurricane-exposed and non-exposed youth. Results were similar across age ranges. Rates of specific internalizing disorders between exposed and unexposed children are provided. Research and clinical implications are discussed.
