The weight of the past: Trauma and testimony in Que bom te ver viva
Authors: Heise Tatiana
Published: June 2017

This article examines representations of trauma in Lúcia Murat’s Que bom te ver viva (How Nice to See You Alive, 1989), a semi-documentary focusing on the experiences of former political militants who, like the director herself, were arrested and tortured under Brazil’s military dictatorship. Despite having limited distribution at the time of release, the film has since gained status as one of the most significant representations of State-sanctioned violence during the 1960s and 1970s. It has received renewed attention more recently as Brazil enters a new period of reckoning with human rights crimes committed during the military regime. I first consider elements of trauma theory and their potential for better understanding the ways in which the film establishes connections between individual suffering and the wider socio-political realm. Essential to the film’s understanding of historical trauma are processes of ‘acting out’ and ‘working through’ which I explore along with the need, partially fulfilled in Que bom te ver viva, to create a witness to traumatic events. This is combined with an examination of stylistic strategies. I argue that the film’s flexible and unconventional aesthetics is a crucial means through which it can represent certain experiences associated with trauma and perform a radical re-envisioning of history.
Remembering objects in the essay film: Andrés di Tella as heir, archaeologist and collector
Authors: Furtado Gustavo Procopio
Published: June 2017

Although Andrés di Tella is among the leading documentary filmmakers in South America, his work has received scant attention in the Anglophone world. Di Tella’s essayistic films mix personal and intimate perspectives with public and historical concerns, crafting a tentative filmic voice that is articulated on the borders between the public and the private. In his subjective explorations of personal and collective pasts, di Tella calls on material objects to play a vital role. Subjective recollections are accompanied by the constitution of collections of objects, material items that are the remainders from and the keys to the past. Remembering is remembering with and through things and senses of self and identity are forged and questioned in dialogue with constellations of objects. This article examines the interaction between subjects and objects in di Tella’s work with special attention to Fotografías (Photographs, 2007) and Hachazos (Ax Blows, 2011).
Non-affirmative time-images in Nuri Bilge Ceylan’s Three Monkeys (2008) and the political aesthetics of New Turkish Cinema
Authors: Katsanis Vuslat D.
Published: June 2017

This article reads Nuri Bilge Ceylan’s award-winning 2008 feature, Three Monkeys, which marks a significant maturity in the political aesthetics developed in New Turkish Cinema over the past fifteen years. Drawing from Deleuze’s theory of the cinematic time-image, and situating the film within Turkey’s particularly turbulent political climate, I try to show how stillness, non-reciprocal sound, ambiguous plot time and extensive long takes in Three Monkeys showcase New Turkish Cinema’s potential to articulate political critique.
Dis/connection across the digital divide: Self(ish) narratives in LOL and Catfish
Authors: Christmas Amy
Published: June 2017

Joe Swanberg’s LOL (2006) and Henry Joost and Ariel Schulman’s Catfish (2010) contribute to a burgeoning wealth of films, across various genres from the science fictional to the factual, that offer documentation and discussion of our contemporary technocultural identities. While the Internet and the virtual spaces it supports have produced an entire generation of digital natives proficient in communication – as the characters in these two incisive films typify – our ability to forge meaningful connections across the digital divide is increasingly thrown into question. In a networked world, we are failing to achieve community, a failure that these films foreground as ontologically destabilizing. Through an analysis of the characters, themes and aesthetics of these works, this article argues that, despite the rich textual infrastructure that the virtual world upholds, our current narrative practices threaten to dilute and dislocate our sense of self.

Argumentation: A Methodology to Facilitate Critical Thinking
Authors: Makhene Agnes
Published: June 2017

Caring is a difficult nursing activity that involves a complex nature of a human being in need of complex decision-making and problem solving through the critical thinking process. It is mandatory that critical thinking is facilitated in general and in nursing education particularly in order to render care in diverse multicultural patient care settings. This paper aims to describe how argumentation can be used to facilitate critical thinking in learners. A qualitative, exploratory and descriptive design that is contextual was used. Purposive sampling method was used to draw a sample and Miles and Huberman methodology of qualitative analysis was used to analyse data. Lincoln and Guba’s strategies were employed to ensure trustworthiness, while Dhai and McQuoid-Mason’s principles of ethical consideration were used. Following data analysis the findings were integrated within literature which culminated into the formulation of guidelines that can be followed when using argumentation as a methodology to facilitate critical thinking.
Excitons in atomically thin 2D semiconductors and their applications
Authors: Xiao Jun , Zhao Mervin , Wang Yuan , Zhang Xiang
Published: June 2017

The research on emerging layered two-dimensional (2D) semiconductors, such as molybdenum disulfide (MoS2), reveals unique optical properties generating significant interest. Experimentally, these materials were observed to host extremely strong light-matter interactions as a result of the enhanced excitonic effect in two dimensions. Thus, understanding and manipulating the excitons are crucial to unlocking the potential of 2D materials for future photonic and optoelectronic devices. In this review, we unravel the physical origin of the strong excitonic effect and unique optical selection rules in 2D semiconductors. In addition, control of these excitons by optical, electrical, as well as mechanical means is examined. Finally, the resultant devices such as excitonic light emitting diodes, lasers, optical modulators, and coupling in an optical cavity are overviewed, demonstrating how excitons can shape future 2D optoelectronics.
Utilization of spent dregs for the production of activated carbon for CO2 adsorption
Authors: Serafin Jarosław
Published: June 2017

The objective of this work was preparation of activated carbon from spent dregs for carbon dioxide adsorption. A saturated solution of KOH was used as an activating agent. Samples were carbonized in the furnace at the temperature of 550°C. Textural properties of activated carbons were obtained based on the adsorption-desorption isotherms of nitrogen at −196°C and carbon dioxide at 0°C. The specific surface areas of activated carbons were calculated by the Brunauer – Emmett – Teller equation. The volumes of micropores were obtained by density functional theory method. The highest CO2 adsorption was 9.54 mmol/cm3 at 0°C – and 8.50 mmol/cm3 at 25°C.
Combination of mesoporous titanium dioxide with MoS2 nanosheets for high photocatalytic activity
Authors: Karimi Loghman
Published: June 2017

This study presents a facile approach for the preparation of MoS2 nanosheet decorated by porous titanium dioxide with effective photocatalytic activity. Mesoporous titanium dioxide nanostructures first synthesized by a hydrothermal process using titanium (III) chloride and then the MoS2/TiO2 were prepared through mixing of MoS2 nanosheet with mesoporous titanium dioxide under ultrasonic irradiation. The synthesized nanocomposite was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), and Brunauer-Emmett-Teller (BET) analysis. The results showed that the nanocomposite has mesoporous structure with specific surface area of 176.4 m2/g and pore diameter of 20 nm. The as-prepared MoS2/TiO2 nanocomposites exhibited outstanding photocatalytic activity for dye degradation under sunlight irradiation, which could be attributed to synergistic effect between the molybdenum disulfide nanosheet and mesoporous titanium dioxide. The photocatalytic performance achieved is about 2.2 times higher than that of mesoporous TiO2 alone. It is believed that the extended light absorption ability and the large specific surface area of the 2D MoS2 nanosheets in the nanocomposite, leading to the enhanced photocatalytic degradation activity.
The Directive 2014/95/EU – Is there a “New” Beginning for CSR in Romania?
Authors: Ogrean Claudia
Published: June 2017

The global commandments of sustainable development, assumed and translated by the EU into a series of communications and resolutions, have found themselves a new (and more powerful) expression into the “Directive 2014/95/EU (…) as regards disclosure of non-financial and diversity information by certain large undertakings and groups”; in order to increase the transparency of their sustainability-related actions and results, these companies need to report (starting from 2018, by referring to the financial year 2017) information “relating to, as a minimum, environmental, social and employee matters, respect for human rights, anti-corruption and bribery matters”. As regards the Romanian companies, although they have had a relatively delayed start in terms of embracing CSR initiatives and practices (and SCR reporting respectively), the Directive 2014/95/EU could represent a great opportunity for diminishing the gap – if properly internalized and strategically operationalized. The paper aims to perform a strategic diagnosis analysis on the CSR practices and CSR reporting in Romania, on the threshold of the Directive 2014/95/EU enforcement, in order to make an effective prognosis on its consequences and impacts.
DHEA protects mitochondria against dual modes of apoptosis and necroptosis in human granulosa HO23 cells
Authors: Tsui Kuan-Hao , Wang Peng-Hui , Lin Li-Te , Li Chia-Jung
Published: June 2017

Because ovarian granulosa cells are essential for oocyte maturation and development, we validated human granulosa HO23 cells to evaluate the ability of the DHEA to prevent cell death after starvation. The present study was aimed to investigate whether DHEA could protect against starvation-induced apoptosis and necroptosis in human oocyte granulosa HO23 cells. The starvation was induced by treatment of serum-free (SF) medium for 4 h in vitro. Starvation-induced mitochondrial depolarization, cytochrome c release and caspase-3 activation were largely prevented by DHEA in HO23 cells. We found that treatment with DHEA can restore starvation-induced reactive oxygen species (ROS) generation and mitochondrial membrane potential imbalance. In addition, treatment of DHEA prevents cell death via upregulation of cytochrome c and downregulation of BAX in mitochondria. Most importantly, DHEA is ameliorated to mitochondrial function mediated through the decrease in mitochondrial ROS, maintained mitochondrial morphology, and enhancing the ability of cell proliferation and ROS scavenging. Our present data strongly indicate that DHEA reduces programmed cell death (apoptosis and necroptosis) in granulosa HO23 cells through multiple interactions with the mitochondrion-dependent programmed cell death pathway. Taken together, our data suggest that the presence of DHEA could be beneficial to protect human oocyte granulosa HO23 cells under in vitro culture conditions during various assisted reproductive technology (ART) programs.

McClintock: An Integrated Pipeline for Detecting Transposable Element Insertions in Whole-Genome Shotgun Sequencing Data
Authors: Nelson Michael G , Linheiro Raquel S , Bergman Casey M
Published: June 2017

Transposable element (TE) insertions are among the most challenging types of variants to detect in genomic data because of their repetitive nature and complex mechanisms of replication . Nevertheless, the recent availability of large resequencing data sets has spurred the development of many new methods to detect TE insertions in whole-genome shotgun sequences. Here we report an integrated bioinformatics pipeline for the detection of TE insertions in whole-genome shotgun data, called McClintock (https://github.com/bergmanlab/mcclintock), which automatically runs and standardizes output for multiple TE detection methods. We demonstrate the utility of McClintock by evaluating six TE detection methods using simulated and real genome data from the model microbial eukaryote, Saccharomyces cerevisiae. We find substantial variation among McClintock component methods in their ability to detect nonreference TEs in the yeast genome, but show that nonreference TEs at nearly all biologically realistic locations can be detected in simulated data by combining multiple methods that use split-read and read-pair evidence. In general, our results reveal that split-read methods detect fewer nonreference TE insertions than read-pair methods, but generally have much higher positional accuracy. Analysis of a large sample of real yeast genomes reveals that most McClintock component methods can recover known aspects of TE biology in yeast such as the transpositional activity status of families, target preferences, and target site duplication structure, albeit with varying levels of accuracy. Our work provides a general framework for integrating and analyzing results from multiple TE detection methods, as well as useful guidance for researchers studying TEs in yeast resequencing data.
Bayesian Networks Illustrate Genomic and Residual Trait Connections in Maize (Zea mays L.)
Authors: Töpner Katrin , Rosa Guilherme J M , Gianola Daniel , Schön Chris-Carolin
Published: June 2017

Relationships among traits were investigated on the genomic and residual levels using novel methodology. This included inference on these relationships via Bayesian networks and an assessment of the networks with structural equation models. The methodology employed three steps. First, a Bayesian multiple-trait Gaussian model was fitted to the data to decompose phenotypic values into their genomic and residual components. Second, genomic and residual network structures among traits were learned from estimates of these two components. Network learning was performed using six different algorithmic settings for comparison, of which two were score-based and four were constraint-based approaches. Third, structural equation model analyses ranked the networks in terms of goodness of fit and predictive ability, and compared them with the standard multiple-trait fully recursive network. The methodology was applied to experimental data representing the European heterotic maize pools Dent and Flint (Zea mays L.). Inferences on genomic and residual trait connections were depicted separately as directed acyclic graphs. These graphs provide information beyond mere pairwise genetic or residual associations between traits, illustrating for example conditional independencies and hinting at potential causal links among traits. Network analysis suggested some genetic correlations as potentially spurious. Genomic and residual networks were compared between Dent and Flint.

Published: June 2017

As taxas de abandono psicoterápico na infância e adolescência são altas, entretanto, são poucos os trabalhos dirigidos para essas faixas etárias. Este artigo investiga o processo terapêutico de um caso de abandono de psicoterapia psicanalítica de uma adolescente. Para tal, foram avaliadas 20 sessões da psicoterapia através do Adolescent Psychotherapy Q-Set (APQ), instrumento que descreve atitudes e comportamentos do paciente e do terapeuta, bem como das interações terapeuta/paciente nas sessões terapêuticas. A análise do APQ foi integrada aos aspectos dinâmicos da paciente e associada às anotações clínicas fornecidas pela terapeuta para a elaboração do entendimento clínico do processo. Concluiu-se que a não aquisição de insight da paciente, aliado a um estilo defensivo imaturo constituíram fatores preditivos ao abandono psicoterápico.
Perception Analysis and Classification of FIT for a Guesthouse: Focused on Comparing Korean and Foreign Independent Tourists
Authors:   The Tourism Sciences Society Of Korea, Oh Jeong-Keun
Published: June 2017

This study used Q methodology to compare, analyze and classify perception contents for a guesthouse as it relates to Korean FIT tourists and Foreign FIT tourists. The results of this research were two fold: First, Korean tourists can be classified into 4 types: type1 ‘Information exchange & communication’, type2 ‘Important special accommodation’, type3 ‘Alternative accommodation’, type4 ‘Travel convenience space’. Second, Foreign tourists can be also be classified four ways: type1 ‘Value efficiency space’, type2 ‘Communication exchange space’, type3 ‘Alternative accommodation for Foreign tourists’, and type4 ‘Interesting culture accommodation’. Common perceptions of Korean and Foreign tourists toward the Guesthouse were analyzed according to alternative accommodation and convenience efficiency space for travel. The discriminative perception focused on functional meaning in terms of Information exchange & the special accommodation needs of Korean tourists. Cultural exchange meaning as a communication exchange and the culture accommodation of foreign tourists were essential parts of this process. These findings offer several implications in terms of political growth and strategic planning for Guesthouses. These include the cultivation of an information system for Korean tourists and the composition of a cultural exchange space for foreign tourists.
Meaning of Short-term Mission Trips: From a Viewpoint of Tourism
Authors:   The Tourism Sciences Society Of Korea, Lee Yoon-Jung
Published: June 2017

This study suggests research themes concerning short-term mission trips(STM) within the tourism field. In spite of the rapid increase of STM travelers and their influence, STM has not been researched as part of the tourism field. STM can be defined as a type of religious tourism and this form of tourism is an integral part of the tourism field. Also, STM travelers have a strong desire to interact with local residents in order to achieve their purpose of evangelism. This means their relationship with local residents is critical. In addition, interaction between hosts and tourists has received considerable attention from tourism scholars. On the contrary, interactions between STMs and local residents have received little attention from tourism researchers. This study argues that STMs are valuable and warrant study within the tourism field and the study expanded the current knowledge base of STMs. From a practical perspective, it is hoped that a better understanding of mission trips will lead organizations to provide support and services for mission trips. This will involve managing relationships between travelers and locals.

Renal cell carcinoma (RCC) occupies one of the leading places in the world for morbidity among malignant neoplasms of the genitourinary system. The frequency of occurrence of bilateral RCC according to different authors is 2–6% of the total population of patients with RCC. Currently, the only effective method of treatment of bilateral RCC is surgical treatment. Patients with bilateral RCC are at high risk of dev eloping of local recurrence or progression of the disease after organ-preserving surgeries, which is why the surgeon is faced with a choice between a high risk of developing renal failure or relapse and/or progression of the disease, depending on the extent of the surgical intervention. According to the literature, in patients with bilateral RCC there was an increase in the incidence of papillary variant of RCC up to 19% and the presence of multifocal lesion. Surgical treatment of bilateral RCC is the only effective method to achieve satisfactory oncological results at a low incidence of complications. The m ost justified option for the treatment of bilateral RCC is the implementation of bilateral organ-preserving treatment, which allows achieving the optimal functional results. This article presents a clinical case of successful surgical treatment of a patient with bilateral RCC with multiple tumors.

ORIENTAÇÃO SEXUAL NA IDENTIDADE DE GÊNERO A PARTIR DA CRÍTICA DA HETEROSSEXUALIDADE E CISGENERIDADE COMO NORMAS
Authors: Pagliarini Bagagli Beatriz
Published: June 2017

Este artigo propõe discutir as formas de como as sexualidades das pessoas trans, transexuais e travestis, assim como dos seus eventuais parceiros cisgêneros, são socialmente interpretadas. Para tanto, iremos partir de um referencial teórico sobre os estudos de gênero e sexualidade e dialogar com relatos e análises de pessoas trans. Observamos como identidade de gênero e orientação sexual, mesmo pertencentes a esferas distintas de constituição de subjetividade, se interseccionam. Pretendemos compreender como estes processos de subjetivação se dão a partir não apenas de uma crítica à heterossexualidade compulsória, mas também à cisgeneridade compulsória. Há, portanto, um ponto em que a crítica à normatividade da orientação sexual toca a crítica à normatividade da identidade de gênero e vice-versa.

Authors: Dos Prazeres Rogério Santos
Published: June 2017

O texto de Régine Robin nos esclarece que a pretensão de buscar a especificação do objeto da sociolinguística não é o mais importante. Entretanto, convém pertinentemente tratar da retomada metodológica crítica ou o uso da metodologia crítica relacionada à sociolinguística. Justamente pelo desencadeamento das reflexões que ela, a sociolinguística, provoca. Numa análise alinhada com às observações teóricas da escola culturalista, acerca das possibilidades entre cultura e linguagem, Robin expõe em seu texto as dificuldades que problematizam o estudo da sociolinguística enquanto estudo científico da linguagem. No presente trabalho, a intenção é contextualizar a perspectiva de sociolinguística primada na publicação de Robin, que é da década de setenta. Contudo, nota-se que questionamentos perpetrados por ela à época permanecem pertinentes hodierno. Sobremodo, situaremos a discussão conservando autores que ela mesma cita em seu texto. A título de evidenciarmos as aporias denunciadas à época. Coerentemente, apontaremos a possibilidade de convergência com a Ética do Discurso de Karl-Otto Apel,uma abordagem atual da linguagem na filosofia. Isso, no sentido de propormos uma investigação mais apurada para saber das consequências de um possível aporte teórico à sociolinguística. Inclusive visando-se possíveis conexões do conhecimento sociolinguístico também discutível na filosofia.

 
EFFECT OF PULSE WIDTH MODULATION ON DC MOTOR SPEED
Authors: Tatenda Katsambe Cosmas , Luckose Vinukumar , Shahabuddin Nurul Shahrizan
Published: June 2017

Pulse width modulation (PWM) is used to generate pulses with variable duty cycle rate. The rapid rising and falling edges of PWM signal minimises the switching transition time and the associated switching losses. This paper presents a DC motor speed controller system using PWM technique. The PWM duty cycle is used to vary the speed of the motor by controlling the motor terminal voltage.The motor voltage and revolutions per minutes (RPM) obtained at different duty cycle rates. As the duty cycle increases, more voltage is applied to the motor. This contributes to the stronger magnetic flux inside the armature windings and the increasethe RPM. The characteristics and performance of the DC motor speed control system was investigated. In this paper, a PIC microcontroller and a DC-DC buck converter are employed in the DC motor speed controller system circuit. The microcontroller provides flexibility to the circuit by incorporating two push button switches in order to increase and to decrease the duty cycle rate. The characteristics and performance of the motor speed controller system using microcontroller was examined at different duty cycle rate ranging from 19% to 99%.

Matrix ranking is an important PRA tool to assess and study the preferences of farmers for a particular technology over others, with respect to crop or animal based technologies. The preferences and criteria for the same are also studied in the process. The following study gives a first-hand idea of farmers’ relative preferences for different varieties of rice, mustard, tomato, chilli, garden pea, fish and lac hosts. The results of the matrix ranking for different varieties of rice revealed that, the variety “Arize 6444” was the most preferred one followed by “Abhishek”. “Pusa Mahak” was the leading variety of mustard followed by Pusa Bold. Swarna Sampada is more preferred tomato variety among the farmers. Among fish, “Rohu” was widely preferred by the respondents due to its higher yield, more market demand, resistance to water quality and higher market price.

The present study was conducted to investigate the polymorphisms of prolactin receptor (PRLR5) gene and its association with egg production in Kadaknath hens. Egg production is a polygenic inheritance trait. Study was conducted on twenty female birds of Kadaknath kept for laying. Egg production performances were recorded as age at first laying (AFE), Body Weight at First Egg (WFE), Mean Egg Weight (MEW) and Total No. of Eggs at 90 days of laying (TEN). Genomic DNA isolated from 2- 3 of blood collected from wing vein of each bird was amplified for prolactin receptor (PRLR5) gene with specific primer by standardizing and optimising the PCR protocols. PCR was performed in a final volume of 20 ml. The amplified PCR products were resolved on the gels to generate polymorphisms. PRLR5 was digested with BamHI. Retriction digested products were run on 2% agarose gel electrophoresis. PRLR5 showed two alleles and two genotypes. The frequency of AA genotype at this locus was 0.75 and BB genotype was 0.25. The AFE (d), WFE (Kg), MEW (g) and TEN of Kadaknath hens in the present study were found to be 188.000.71, 1.260.03, 42.830.21 and 37.750.59 respectively. Birds with AA genotype of PRLR5 had a significantly (P less than 0.05) better WFE and AFE than BB genotype. Prolactin receptor (PRLR5) genes produced polymorphism in Kadaknath and were associated with egg production traits.

Published: June 2017

In the present study, sterilized rice bran was fermented for 48, 72 and 96 hours by Aspergillus flavus and proximate analysis indicated that fermentation changed nutritive value of the rice bran. Four experimental feeds were fed to 4 groups of day old broiler chicks for 6 weeks to evaluate their effects on broiler performance (weekly feed intake, weight gain, FCR and mortality). During first 2 weeks, birds of group D showed significant difference (P less than 0.05) in feed intake and weight gain as compared to groups A (control), B and C. All groups did not show significant differences in feed conversion ratios (FCR). During 3rd week of trial, chickens of Group D showed significant difference (P less than 0.05) in feed intake, weight gain and FCR as compared to group A. During last 3 weeks, birds in group D showed significant difference (P less than 0.05) in feed intake, weight gain and FCR as compared to birds of groups A, B and C. Group D showed significantly higher weight gain and better FCR (P less than 0.05) as compared to groups A, B and C. On the whole, broiler chickens fed on 96 hours fermented rice bran showed best growth performance. In-vivo phytase activity was determined in ash of tibia bones collected from selected birds in each group. Group D showed significantly high percentage (P less than 0.05) of ash and phosphorus in tibia bones as compared to groups A (control), B and C. In conclusion, fermented rice bran showed beneficial effect on broiler performance and could be used in poultry feed as phytase source.

Published: June 2017

En este trabajo se sintetizaron nanopartículas de plata mediante el proceso de poliol, que reduce el nitrato de plata con glicol de etileno. Se estudió el efecto de la temperatura y la cantidad de polivinilpirrolidone (PVP). Las temperaturas utilizadas fueron 100, 120 y 140 °C. Se establecieron tres relaciones: de 0.00; 0.25 y 0.50 (% w/w) de PVP/AgNO3. Las nanopartículas con tamaños menores de 30 nm se obtuvieron en condiciones de 120 °C y 0.5 (% w/w) de PVP/AgNO3.Las nanoparticulas obtenidas en concentraciones de 10 y 20 ppm fueron luego depositadas en telas de algodón, mediante la técnica “pad-dry-cure” (tela curada y seca), a fin de analizar sus propiedades contra la bacteria Gram positiva Staphylococcus aureus 25923. Las pruebas mostraron que las telas de algodón con una concentración de 10 y 20 ppm tenían buenas propiedades bactericidas, debido a la reducción de las colonias de bacterias por encima del 98 %. Finalmente, se llevó a cabo un estudio de estabilidad del lavado de las telas impregnadas con las nanopartículas de plata, y, además, se utilizó un ligante acrílico durante el proceso de impregnación. Los resultados se obtuvieron mediante análisis bacteriológicos.

Published: June 2017

Introducción: en algunos estudios se ha reportado que los universitarios no tienen un estilo de vida saludable (EVS) por lo que es necesario identificar no solo las variables psicosociales negativas, sino también las variables de Psicología Positiva que pueden favorecerlo.Objetivo: Determinar la relación entre el capital psicológico (CapPsi) y el estilo de vida (EV) de estudiantes universitarios mexicanos.Método: se realizó un estudio transversal y correlacional con 320 estudiantes de una universidad pública. La muestra fue no probabilística por cuotas. Para evaluar los factores del CapPsi se utilizaron los instrumentos Escala General de Autoeficacia, Escala de Esperanza para Adultos, Cuestionario de Resiliencia y Test de Orientación en la Vida (optimismo); para evaluar el EV se usó el Cuestionario Fantástico.Resultados: las variables del CapPsi mostraron una correlación estadísticamente significativa con el EV; resiliencia (r = 0,505, p < 0,01); esperanza (r = 0,432, p < 0,01); optimismo (r = 0,412, p < 0,01); autoeficacia (r = 0,400, p < 0,01). El 33,3 de la varianza total del EV es explicado por el CapPsi (R2 = 0,333).Conclusiones: con base en los resultados, se asume que el CapPsi favorece el EVS; no obstante, es necesario que futuras investigaciones detallen si la influencia es en la adopción y/o mantenimiento del EVS, así como identificar cómo influye particularmente en cada factor del EV. El CapPsi tiene un porcentaje representativo de predicción del EV saludable. Es necesario que los programas de promoción y prevención en salud incorporen el abordaje del CapPsi para lograr un EV saludable en los universitarios.
Adherence to the Mediterranean diet pattern, cognitive status and depressive symptoms in an elderly non-institutionalized population
Authors: Hernández-Galiot Ana , Goñi Isabel
Published: June 2017

Abstract: Introduction: Scientific evidence indicates that adherence to the Mediterranean diet protects against the deterioration of cognitive status and depressive symptoms during aging. However, few studies have been conducted in elderly non-institutionalized subjects. Objetive: This study evaluated the relation between the adherence to the Mediterranean dietary pattern and cognitive status and depressive symptoms in an elderly population over 75 years. Methods: A cross-sectional study was conducted in a Mediterranean city (Garrucha, Spain) in 79 elderly people over 75 (36 men and 41 women). Adherence to the Mediterranean dietary pattern was determined using the Mediterranean Diet Adherence Screener (MEDAS). Cognitive function was determined by the Mini Mental State Examination (MMSE), and depressive symptoms were assessed by the Geriatric Depression Scale (GDS). Results: Most of population showed a very high adherence to the Mediterranean diet pattern and optimal cognitive and affective status. They consumed olive oil as their main source of fat, high levels of fish and fruit, low levels of foods with added sugars, and a low consumption of red meat. A significant inverse relation between the MEDAS and MMSE scores was found. However, no relationship was observed between the MEDAS and GDS.Conclusions: The Mediterranean diet pattern was positively related with the cognitive function, although the influence of a healthy dietary pattern on the symptomatology of depression was unclear. However, an effective strategy against cognitive function and depression would be to improve physical activity rates, establish lifelong healthy eating habits, and consume a nutritionally-rich diet in order to enhance quality of life of the elderly.
