Authors: Sedghi Mahlagha , Basavaraj Prateek , Garibay Ivan , Ozmen Garibay Ozlem , Ratan Guha Arup
Published: May 2021

Las instituciones de educación superior tradicionalmente miden el éxito de los estudiantes y la calidad de un programa académico mediante métricas estándar, como el tiempo que tarda un estudiante en obtener un título, las tasas de graduación y las tasas de retención. Además, algunos programas han instituido un "examen de calificación" como una forma alternativa de medir la calidad de un programa académico y evaluar el dominio del estudiante en los conceptos básicos. El programa de Ciencias de la Computación (CS) de la Universidad de Florida Central implementó un examen de calificación "Examen básico" en 1998 con el propósito de evaluar el dominio de los estudiantes de los conceptos básicos de CS y controlar la calidad del programa. Sin embargo, las tasas de aprobación de los estudiantes que tomaron este examen de calificación fueron significativamente bajas a lo largo de los años. Además, algunos estudiantes retrasaron sistemáticamente la realización de este examen por temor a reprobar. Para reflejar las credenciales de conocimiento que necesita la industria, promover el dominio de los conceptos básicos de informática y ayudar a los estudiantes a graduarse de manera oportuna, se implementaron recomendaciones de mejora basadas en datos en 2016. Después de que se realizaron las mejoras, muchos más estudiantes intentaron el examen a tiempo y progresaron en su título en los años 2016-2018. Los detalles de estas mejoras y su impacto se presentan en este documento.

Trace element accumulation by soils and plants in the North Caucasian geochemical province
Authors: Alekseenko Vladimir , Shvydkaya Natalya , Bech Jaum , Puzanov Alexander , Nastavkin Aleksey
Published: May 2021

Long-term studies of the North Caucasian geochemical province allowed to establish regional abundances and calculate accumulation (dispersion) factors for chemical elements in rocks, soils, and plants. Certain natural regional patterns characterize the province. Associations of elements in high and low concentrations are often determined by the predominant composition of rocks: carbonate-terrigenous, terrigenous, and igneous. The study of the average contents of several chemical elements in the soils of the province showed that the association of accumulated elements includes metals with different migration characteristics. Thus, despite the rather close values of the ionic radii, Pb, Zn, Cu, and Li (judging by the ionic potential) are characterized by the formation of cations, while Mn, Mo, and Zr form complex ions. Such elements as Zn, Cu, and Pb are mainly accumulated on hydrosulfuric barriers, while Mo, Co, and Mn are stopped by oxygenous barriers. For Cu, Zn, Mo, and Co, biogenic accumulation plays a significant role, while for Pb and Ni it is practically absent. The absolute dispersion of the elements did not reach environmentally hazardous values, although it indicates a fairly intensive migration. In woody plants, Ba, Nb, Sc, Sr, and Zn are accumulated most intensively.

Circular Economy: Barriers and Levers Promoting Transformation (Case Study Analysis)
Authors: Ivanova Vania
Published: May 2021

Innovative projects, connecting the circular economy with sustainable territorial development, promote multiple synergic effects, thus helping to dynamite the various aspects of sustainable development – economic, social, and ecological. In order for such projects to succeed, however, some conditions must be in place at the same time. The aim of this research is, based on some projects selected according to a set of criteria, to analyze the levers and barriers to developing new business models built on the circular economy principles. An exhaustive study of each of these projects and a comparative analysis allow us to derive some common features and develop a typology that makes it possible to identify and shed light on the new requirements, conditions, and factors for the successful realization of projects of similar type. Also, concrete recommendations are given concerning the necessary support from national and local public authorities. The study is based on primary and secondary sources and applies the causal approach, analysis, synthesis, and survey.
Unsupervised Learning for Hydrogen Breath Tests
Authors: Netzer Michael , Hanser Friedrich , Ledochowski Maximilian , Baumgarten Daniel
Published: May 2021

Hydrogen breath tests are a well-established method to help diagnose functional intestinal disorders such as carbohydrate malabsorption or small intestinal bacterial overgrowth. In this work we apply unsupervised machine learning techniques to analyze hydrogen breath test datasets. We propose a method that uses 26 internal cluster validation measures to determine a suitable number of clusters. In an induced external validation step we use a predefined categorization proposed by a medical expert. The results indicate that the majority of the considered internal validation indexes was not able to produce a reasonable clustering. Considering a predefined categorization performed by a medical expert, a novel shape-based method obtained the highest external validation measure in terms of adjusted rand index. The predefined clusterings constitute the basis of a supervised machine learning step that is part of our ongoing research.
Digital Health Intervention to Support Refugees in Switzerland
Authors: Romao Patricia , Neuenschwander Stefanie , Denecke Kerstin , Nüssli Stephan
Published: May 2021

Experiences of war and persecution often lead to mental health problems, resulting in post-traumatic stress disorders. In this work, we design a digital platform that aims at helping refugees coming to Switzerland by providing exercises for their mental health and information about daily life in Switzerland. In collaboration with the Swiss Red Cross (SRC), we collected requirements and developed a concept for information provision through in this platform. The architecture of a progressive web application (PWA) was identified as to best fulfill the given requirements. Based on the collected requirements mockups were created. In user interviews, we received feedback regarding the future system. We learned that the platform should include an avatar, which guides the user through the entire platform and asks questions. All texts should be accessible by a read-aloud function and exercises should be provided as videos. In summary, we learned that it is essential to involve the future user group in the development process since it is characterized by cultural diversity that has to be considered in the development and design. Enriched by this input, the next step is to realize the application in terms of a prototype.

Published: May 2021

Background: Mobile apps may encourage a lifestyle that avoids unhealthy behaviors, such as smoking or poor nutrition, which promotes cardiovascular diseases (CVD). Yet, little data is available on the utilization, perception, and long-term effects of such apps to prevent CVD. Objectives: To develop a mobile app concept to reduce the individual CVD risk and collect information addressing research questions on CVD prevention while preserving data privacy and security. Methods: To validate the concept, a prototype will be built, and usability studies will be performed. Results: We expect to determine whether it is possible to reach a broad user base and to collect scientific information while protecting user data sufficiently. Conclusion: To address CVD prevention, we propose a mobile coaching app. We expect high acceptance rates in validation studies.
Consumo de alcohol en niños y adolescentes: prevalencia en países del cono sur de América Latina, factores de protección y factores de vulnerabilidad
Authors: Salguero Agustín , Leiva Lorena , Luque Maribel , Pautassi Ricardo
Published: May 2021

This narrative and non-systematic review describes data and trends on the prevalence of alcohol consumption in children and adolescents, with focus on work in the southern region of Latin America; likewise we describe some factors, and research associated with sustainability, the regulation of alcohol consumption, particularly in children and adolescents. The relevant data on the age of onset of alcohol consumption has been decreasing over time and the prevalence of alcohol consumption has been of greater importance, as has the consumption of 4 - 5 drinks per occasion of consumption. We describe the factors that open the doors to preventive treatments or interventions, highlighting the issue of practices based on social norms, the challenge of knowledge about substance use. Unlike personality or biological factors, these beliefs are susceptible to modification through economic and simple ones.

Published: May 2021

En este trabajo se reflexiona sobre la formación universitaria del futuro profesorado de Primaria. La sociedad actual está viviendo una crisis de valores como consecuencia, entre otros factores, de las políticas del libre mercado. Ello pone en entredicho a la educación superior. Considerando este momento de crisis como una era de cambio de paradigma surgen este y otros interrogantes: ¿qué supone la crisis de valores en la educación superior del profesorado? La revisión de la literatura muestra que el proceso de enseñanza–aprendizaje no es posible sin otros procesos no cognitivos del orden de la emoción. Desde este trabajo consideramos imprescindible capacitar al profesorado de Primaria para esta compleja realidad donde se desarrollan las relaciones pedagógicas. Para ello, la supervisión en el contexto universitario resulta necesaria en la formación del futuro profesorado porque favorece la toma de conciencia en la práctica profesional y ayuda a consolidar su identidad como docente.
Comparison of moss bag and native moss technique in monitoring airborne particulate and toxic elements
Authors: Nguyen Son An , Thi Minh Sang Nguyen , Hong Khiem Le
Published: May 2021

Introduction: In Vietnam, the government has invested in monitoring stations in a few big cities like Hanoi and Ho Chi Minh City, which have transportation centers and industrial zones, to assess and predict levels of air pollution. However, the main disadvantage of installing monitoring stations is the cost of investment for operations, maintenance, and equipment. It is also time-consuming to collect and analyze the results. Therefore, it is generally not suitable for the country as a whole.

Methods: Using mosses to monitor air quality brings qualitative and quantitative data with simple, environmentally-friendly economic methods. Mosses have particular biological characteristics that make them very suitable adsorbents for a wide variety of chemical elements. When used as transplants like moss bags, allow them to monitor a highly dense sampling network of any site easily. Mosses are bioindicators, plants with artificial roots.

Results: In this study, moss bag and native moss were the two methods used to evaluate the accumulation of trace elements in air through Barbula Indica. Observations showed that both methods could detect the same elements: Al, Si, P, S, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, Rb, Y, Sb, Ba, Pb, and U. However, the accumulation of the elements in native moss is higher than in moss bag. The main reason is that the absorption efficiency of native moss in air-deposited elements is higher than in moss bags.

Conclusion: Moss bags have been used most extensively and successfully in urban areas, where vegetation samples are either unobtainable or are poorly located to the source. These areas can lack moss, or the native moss simply does not grow during the dry season.

L'insegnamento delle discipline psicologiche nei corsi di laurea in Medicina e Chirurgia: il contributo di Marcello Cesa-Bianchi
Authors: Cipolli Carlo , Poli Marco
Published: May 2021

Marcello Cesa-Bianchi (1926-2018) è stato professore ordinario di Psicologia generale per 40 anni nella Facoltà di Medicina e Chirurgia dell'Università Statale di Milano. Una parte rilevante della sua attività istituzionale è stata indirizzata alla valorizzazione delle funzioni didattiche delle discipline psicologiche nellaformazione degli studenti dei corsi di laurea in Medicina e Chirurgia. Questo obiettivo è stato perseguito fin dagli anni '70, in parallelo con a) l'evoluzione delle competenze richieste ai nuovi medici dal nuovo approccio centrato sul paziente in medicina, b) l'incremento di complessità delle attività cliniche all'interno degli ospedali generali, c) l'armonizzazione dei corsi di studio per la formazione dei medici come presupposto per la loro libera circolazione negli stati aderenti alla Comunità (poi Unione) Europea.L'avvio di questo processo di armonizzazione, all'inizio degli anni '80, fornì l'opportunità di coordinare le indicazioni derivate da esperienze didattiche innovative realizzate in alcune facoltà mediche (in particolare, nelle Università di Milano Statale, Bologna, Napoli Federico II) e di presentarle alle commissioni ministeriali impegnate prima nella revisione dell'ordinamento didattico del Corso di Laurea in Medicina e Chirurgia nel 1986 (la cosiddetta Nuova Tabella XVIII) e nel suo adeguamento nel 1996, e poi al definitivo ordinamento, nell'ambito della generale riorganizzazione degli studi universitari disposta dal Decreto Legislativo n. 509 del 1999.Per stimolare le innovazioni nella didattica delle discipline psicologiche e la presentazione di proposte ufficiali per le modifiche degli ordinamenti didattici prima del Corso di Laurea in Medicina e Chirurgia e poi di tutti i corsi di laurea e laurea specialistica dell'area sanitaria Cesa-Bianchi promosse numerosi convegnia partire dal 1986 e la costituzione del Collegio dei docenti e ricercatori di discipline psicologiche nelle Facoltà di Medicina e Chirurgia nel 1993. Attraverso questo organismo vennero elaborate e presentate ufficialmente le proposte che hanno portato ad inserire definitivamente la psicologia generale tra le discipline per la formazione di base del medico e dei laureati delle professioni sanitarie, e la psicologia clinica tra le discipline caratterizzanti per gli stessi corsi di studio. Un risultato altrettanto importante e duraturo è stato l'inserimento di specifiche competenze professionali (comunicative relazionali) da acquisire attraverso le discipline psicologiche.
Pandemia: tra la paura e Mister Hyde
Authors: Mazzeo Riccardo
Published: May 2021

In questa congiuntura vediamo in atto una paura manifesta, sana, una totale assenza di paura, ovvero una negazione che diventa pericolosa, e la paura più dif-fusa, quella strisciante dell'Angst o angoscia esistenziale. Il più efficace antidoto alla paura è il dialogo insieme alla cooperazione, la riflessione e l'introspezione. La pandemia ci "rivela" che, come ne La peste di Camus non è dato salvarsi da soli e che non possiamo continuare a sentirci antropocentrici: se consideriamo il creato un emporio ci ritroviamo poi a pagare un prezzo inaudito. Nonostante l'oggettiva capitalizzazione del coronavirus da parte di persone senza scrupoli che ne appro-fittano per perseguire i propri interessi, il negazionismo è stupido e spesso letale per sé e per altri. La smaterializzazione dei rapporti che tendono, ancora più di prima, a essere mediati dagli schermi, rischiano per un verso di alimentare un Super-io sa-dico dei lavoratori da remoto, impegnati nel loro compito senza interruzione, per l'altro a disabilitare rispetto alle competenze fatte di sfumature del dialogo off line. Oltre ad accentuare le diseguaglianze, il Covid contribuisce a far emergere il nostro lato sconosciuto, il perturbante che ci accompagna e con cui dobbiamo riuscire a convivere.
Bouncing forward in challenging times
Authors: Kralt Jeannine , Cole Donald
Published: May 2021

The COVID-19 pandemic is a disruption which has posed challenges to food sector organizations. Yet it may also provide an opportunity for growth of and change in these organizations. Our aims were to describe the surge in demand and innovations introduced by a rural food distribution cooperative and to critically assess responses in light of organizational resilience literature. We chose an organizational case study approach with mixed methods. Data sources included: existing reports, newsletters, policies and quantitative indicators; and new stakeholder interviews (n=20). We describe: the development and nature of the cooperative; its consolidation and anticipatory planning; the March 2020 surge in orders (133/week in February to 205/wk in March); the prioritization of health and safety in modifying product receiving and delivery methods; the warehouse reorganization and product aggregation doubling to twice per week; the strains on employees and human resource challenges; yet the growing organizational resilience.  We reflect on the small role of the cooperative in the inequitable agri-food system of the counties it serves, yet the strong role it plays with other food security oriented organizations in keep with its values. Further work, both research and practice development, can continue to explore the ways in which complex multi-stakeholder, not-for-profit, socially and environmentally principle food organizations can better navigate disruptions in the coming years, particularly in rural areas.

Authors: Hakim Arief Rahman , Pakpahan Aston
Published: May 2021

Salah satu tujuan dalam pembangunan daerah dan pembangunan nasional adalah penyerapan tenaga kerja dan penurunan pengangguran. Studi tentang penyerapan tenaga kerja selama ini hanya dilakukan dengan pendekatan ekonomi (economic base) yang melihat aspek tenaga kerja dari sisi permintaan saja. Kondisi ini kurang lengkap karena mengabaikan sisi penawaran. Perlu dilakukan studi yang lebih komprehensif dari aspek ekonomi sebagai sisi permintaan dan aspek demografi sebagai sisi penawaran. Pendekatan ini dikenal sebagai model Demometrik.

Penelitian bertujuan mengkaji faktor-faktor yang mempengaruhi penyerapan tenaga kerja dengan model demometrik. Aspek ekonomi yang dikaji adalah investasi dan tingkat upah, sedangkan aspek demografi yang diteliti adalah jumlah penduduk. Data yang digunakan dalam penelitian ini berasal dari seluruh 14 kabupaten/kota di Provinsi Kalimantan Tengah pada periode 2010 – 2019 (9 tahun, dikurangi data tahun 2016). Analisis data dilakukan dengan regresi linear berganda data panel sederhana.

Hasil penelitian menunjukkan bahwa variabel investasi dan jumlah penduduk berpengaruh posituf dan signifikan terhadap penyerapan tenaga kerja sedangkan upah minimum regional tidak berpengaruh terhadap penyerapan tenaga kerja.

Indexing the humanities knowledge in the Library Bibliographic Classification
Authors: Volkova N. A. , Khodanovich M. A.
Published: May 2021

Changing scientific knowledge entails the exclusion of some areas of research and inclusion of others into the main line of development of science, with the new publications revising well-established concepts and offering the new ones. Any rational reconstruction of the history of science has to identify the line of development that has resulted in the modern knowledge.

The Soviet Library and Bibliographic Classification developed in the mid-20th century responded to the challenges of the epoch. The paradigm shift of the 1990s in this country resulted in the conceptual revision of scientific values and the emergence of new academic disciplines. That period gave rise to applied studies with their specific goals and values, standards and norms.

In the recent period, the humanities studies proliferate to construct generalized interdisciplinary theory. The vast number of publications in the humanities knowledge suggests that the appropriate place for these studies within the structure of the national Library Bibliographic Classification has to be found.

Objetivo: avaliar a efetividade da acupuntura auricular em estudantes de graduação com níveis variados de estresse. Materiais e métodos: Trata-se de um estudo quantitativo de natureza experimental, controlado, com dois grupos: intervenção e controle. Para definir a amostra dos sujeitos participantes foi utilizado o Inventário de Sinais e Sintomas de Stress de Lipp – ISSL, em seguida aqueles que obtiveram estresse positivo fizeram uma sessão semanal de 15 minutos à 1 hora durante quatro semanas. Para o grupo intervenção os pontos escolhidos foram: Shen Men, Fígado, Pulmão/Coração, Rim e ansiedade. O grupo controle teve os seus pontos escolhidos de acordo com as queixas apontadas. Após a última sessão os estudantes responderam o ISSL. Resultados: Participaram do estudo 27 estudantes e foi encontrada relação significativa entre sexo, idade, tempo de deslocamento para a faculdade, número de transportes e participação em projetos extracurriculares. Estes foram divididos em grupo intervenção (13) e grupo controle (14). Após a acupuntura auricular, no grupo intervenção, foi obtido um aumento de 30,7% de estudantes sem estresse e no grupo controle, esse aumento foi de 64,3%, aproximadamente duas vezes maior que no primeiro. Considerações finais: Permite-se concluir que as taxas de estresse dos participantes estão próximas às encontradas em outros estudos, e que a acupuntura auricular demostrou ser uma técnica que pode auxiliar na redução dos sinais e sintomas de estresse nesta população.
Effect of stimulation of sublobule IX-b of the cerebellar vermis over cardiac function
Authors: Rocha I , Gonçalves V , Bettencourt MJ , Silva-Carvalho L
Published: May 2021

Activation of sublobule IX-b of the cerebellar vermis evokes
hypotension, bradycardia and decrease of the phrenic nerve
activity in the anesthetized animal. Cardiac performance during
the isovolumic phases of systole and relaxation can be evaluated
by dP/dtmax, Vpm, dP/dt/DP40 and τ, respectively. In the present
study, we evaluated the changes on cardiac function evoked by
the stimulation of sublobule IX-b. New Zealand white rabbits
were anesthetized, paralyzed and artificially ventilated. A
posterior craniotomy was made to reveal and stimulate the
cerebellar uvula (4 s train; 50 Hz; 1 ms; 20 μA). The femoral
artery and veins were cannulated and a Swan-Ganz catheter was
advanced in the upper abdominal aorta to control afterload when
inflating the balloon. The left ventricle was catheterized with a
Millar catheter. Blood pressure, heart rate, left ventricular
pressure were monitored. Results showed a significant decrease
on sublobule IX-b stimulation of all the indices of systolic function
and an increase of τ indicating a decrease in the speed of the
relaxation. These data provide the first evidence of the influence
of sublobule IX-b on cardiac function. They may contribute to the
understanding of the origin the cardiovascular changes that were
observed in two patients with vermian and paravermian
hemorrhage.
Integrative pattern of vasomotor efficiency in SHR during ontogenesis
Authors: Gerová M , Kristek F
Published: May 2021

Numerous studies concerning the cardiovascular system in SHR
often yield controversial data. The background of this diversity
has various roots, ranging from different vascular segments or
areas studied up to the different age of experimental animals.
Our study aimed to follow the BP as an integrated response of
vascular system. This approach was justified since stabilized
cardiac output in SHR was proved till 1 year of age. The groups
of male SHR (aged 3, 5, 9, 17 and 52 weeks) and age-matched
Wistar rats were used. Significant basal BP difference between
SHR and Wistar rats was found at 9 weeks of age and continued
till the age of 52 weeks, reaching 189.6±11.9 mm Hg in SHR and
117.3±6.9 mm Hg in Wistar rats (P<0.01). The significant
difference in BP increase to two doses of noradrenaline (0.1 μg
and 1 μg) between SHR and control rats was also found at the
age of 9 weeks. At 52 weeks the BP increment to two doses of
noradrenaline was in SHR 19.7±2.0 mm Hg and 60.5±3.9 mm Hg
and in Wistar rats 7.4±1.9 mm Hg and 40.5±3.2 mm Hg
(P<0.01). The hypotensive response to acetylcholine (0.1 μg,
1 μg and 10 μg) in SHR was enhanced at 17 weeks of age only
and this amplification persisted till the age of 52 weeks. In 52-
week-old SHR the hypotensive response to three doses was
69.9±10.2 mm Hg, 87.5±11.8 mm Hg and 103.4±10.6 mm Hg,
while in Wistar rats it was 37.4±4.2 mm Hg (P<0.01), 62.3±3.5
mm Hg (P<0.01) and 73.5±2.8 mm Hg (P<0.05). In conclusion,
the efficiency of cardiovascular system of SHR to respond to
noradrenaline was already enhanced from 9 weeks of age,
whereas the response to acetylcholine was not augmented
before the age of 17 weeks.
In vivo study of the effect of antiviral acyclic nucleotide phosphonate (R)-9-[2- (phosphonomethoxy) propyl]adenine (PMPA, tenofovir) and its prodrug tenofovir disoproxil fumarate on rat microsomal cytochrome P450

Published: May 2021

The total content of rat liver microsomal cytochrome P450 (CYP)
significantly decreased after repeated i.p. administration of the
antiviral agent tenofovir ((R)-9-[2-(phosphonomethoxy)propyl]
adenine) and tenofovir disoproxil at a daily dose 25 mg/kg,
although the content of liver microsomal protein did not change.
The decrease of the CYP content was accompanied by
concomitant increase of the amount of inactive CYP form,
cytochrome P420. This effect was confirmed by a parallel study
of the activities of selected CYP forms, CYP2E1 (p-nitrophenol
hydroxylation) and CYP1A2 (7-ethoxyresorufin deethylation). The
activity (expressed relatively to the protein content) of both CYP
forms decreased significantly following the decrease of the total
CYP. On the other hand, the CYP2E1 activity expressed relatively
to the decreasing total CYP content remained unchanged.
However, CYP1A2 activity also decreased when calculated
relatively to the total native CYP content indicating lower stability
of this form. Semiquantitative RT-PCR showed no significant
changes in expression of major rat liver microsomal CYP forms
after tenofovir treatment. In conclusion, repeated administration
of tenofovir in higher doses led to significant decrease of the
relative proportion of active liver microsomal CYPs accompanied
by a conversion of these enzymes to the inactive form (CYP420)
maintaining the sum of CYP proteins unchanged.
Scotland's Gàidhealtachd Futures: an introduction
Authors: Oliver James , MacKinnon Iain
Published: May 2021

This special issue of Scottish Affairs is the first to be solely dedicated to matters relating to Scotland's Gàidhealtachd. Scottish Affairs has a broad, interdisciplinary readership and this informs our approach as guest editors for the special issue. As such, the focus for the issue is to be future-oriented, whilst necessarily being informed by cultural context, contemporary society and lived experience. By curating the articles in these terms, an aim is to encourage an ethic of engagement with a spectrum of topics (not exhaustive) of contemporary research and debate of relevance to the Gàidhealtachd, and to encourage relational perspectives and creative horizons across that spectrum. Therefore, the special issue is not constrained by a single disciplinary focus or structure; although, in important, different ways, the articles are oriented to forms of disciplinarity and practice. This emphasis on emerging debates within the Gàidhealtachd includes their intersections and orientations with situated experiences, subjectivities and voices. Whilst the theme of the special issue is ‘futures’, this is not in a superficially speculative or unproductive sense. Rather, it is ontologically oriented: to the spaces and cultural articulations of encounters and entanglements of people, places and social or community networks. Nevertheless, and not least because of the finite space afforded in a collection or volume of writing, the special issue does not claim to be representative of all dimensions, experiences or understandings of the Gàidhealtachd. Some are yet to come – sin mar a tha e.
Misplaced Women?
Authors: Ostojić Tanja
Published: May 2021

Misplaced Women? is an ongoing interdisciplinary art project (2009-2017) by Tanja Ostojić that has been conceived as both an internet—platform and a real platform organized in public spaces in the cities across the globe to discuss the issues of migration, displacement, security, privacy, and exposure. It is manifested in a series of performances by the author herself, as well as delegated performances, individual or group performances predominantly by women, and performance workshops conducted by Tanja Ostojić herself. Essentially, the performance score might include unpacking, rummaging and detailed searching of the entire content, pockets, purses, wallets, personal suitcases and bags on sites that are relevant to migration, such as airports, train stations, Western Union Money Transfer services, police stations for foreigners who want to obtain residence permits, etc. Participants performing at authentic locations might repeat similar actions that build upon the basic proposal of the Misplaced Women? concept, i.e. they deal with positions andexperiences of people in transit, migration, and exile.
Penetrabilidad cognitiva en la percepción visual temprana: Evidencia empírica en humanos
Authors: Arévalo Pachón Guillermo
Published: May 2021

Con base en un trasfondo teórico sobre las concepciones modulares de la mente de Fodor (2001) y Pinker (2005), el objetivo del presente texto es analizar cualitativemente la solidez de la evidencia experimental de una muestra de artículos publicados entre 2002 y 2017 que apoyan la tesis de la penetrabilidad cognitiva en la percepción visual temprana. El estudio se justifica por las implicaciones que pueden tener los resultados de estas investigaciones para las diferentes concepciones sobre arquitectura mental en funciones perceptuales, procesamiento de la información intra e intermodular e isomorfismo entre arquitectura mental y cerebral. La metodología que se utilizó para realizar este estudio implicó establecimiento de la tesis y de los criterios de inclusión de los artículos a revisar, selección final de los artículos más representativos sobre las subáreas seleccionadas, análisis de la calidad metodológica y de los resultados de éstos, identificación de aportes específicos de cada estudio a la tesis planteada e interpretación y síntesis de los hallazgos. De 26 artículos revisados sobre el tema, se reportan y analizan 7, que se consideran representativos de 4 subáreas: penetrabilidad de expectativas, de percepción del color, de rasgos faciales y de reconocimiento de objetos. Se concluye que hay amplia y sólida evidencia convergente (perceptual y neurofisiológica) a favor de los fenómenos penetrativos en la visión temprana, lo cual apoyaría indirectamente la hipótesis de permeabilidad de los módulos mentales de Pinker. Se formulan recomendaciones sobre aspectos por investigar y variables a controlar en experimentos sobre este tema.
Redes sociales, autoeficacia academica y bienestar en adolescentes de la zona Maya de Yucatan
Authors: Sánchez Escobedo Pedro Antonio , Gómez-Rivero Mariel Alejandra
Published: May 2021

The relationship between the use of social networks and the students´ academic self-efficacy and perception of wellbeing is explorer in adolescents from the Mayan zone of the Yucatán, Mexico. Three instruments exploring these variables were administered to 1013 students form 7th and 9th grades.   Access to social network in these adolescents seem to be like those in the cities, suggesting some equity in these two contexts. Results evidences no significant relationships between the variables, expect from the logical significant relationship between high self-efficacy and better school grades.  Women scored higher in every dimension of wellbeing and reported higher expectations for college entrance than men. Nine graders scored lower both in self efficacy and perceptions of wellbeing, maybe because to developmental issues associated to adolescence. This higher perception of wellbeing in rural women deserves further considerations in view of commonly held beliefs that women in rural context are in vulnerability and disadvantage in comparison to men.
Mother Behavior Q-Set (MBQS)Dimensionalidad del Q-set del comportamiento materno en muestras de México, Colombia y Uruguay

Published: May 2021

La sensibilidad se refiere a la capacidad del cuidador para percibir las señales del niño, interpretarlas correctamente y responder a ellas de manera contingente y apropiada. El Q Set del Comportamiento Materno (MBQS) fue creado a partir de descripciones teóricas y empíricas de la sensibilidad. Los Q-sorts se asocian con la metodología cuantitativa debido a que asignan puntajes; además, combinan la metodología cualitativa al hacer un estudio sistemático de la subjetividad. Son pocos los artículos que se ocupan de explorar el análisis, la validez interna, la confiabilidad o la replicabilidad externa de los Q-sorts. Usualmente los datos se reducen por medio de un análisis de componentes principales o análisis factorial. Sin embargo, en los Q-sorts se correlacionan los participantes para dilucidar las relaciones entre ellos en lugar de correlacionar las variables. El objetivo de la presente investigación fue encontrar evidencia respecto a la validez basada en la estructura interna del MBQS con el apoyo del software R y el paquete qmethod. Colaboraron 37 díadas mexicanas mamá-bebés, 35 colombianas y 24 uruguayas. En el 2002, Posada y colaboradores propusieron siete escalas. Las escalas en las que nuestro modelo factorial presentó un buen ajuste son las que tienen menos ítems, lo cual puede ser indicativo de que la falta de ajuste tiene que ver con la identificación del modelo debido a que se cuenta con pocas observaciones. Consideramos que tanto el uso del MBQS para evaluar la sensibilidad como del paquete qmethod para realizar el análisis resulta novedoso, relevante y pertinente.
The Emerging Application of Itaconate: Promising Molecular Targets and Therapeutic Opportunities
Authors: Lin Jiaqi , Ren Jinxuan , Gao Dave Schwinn , Dai Yi , Yu Lina
Published: May 2021

Metabolites have recently been found to be involved in significant biological regulation and changes. Itaconate, an important intermediate metabolite isolated from the tricarboxylic acid cycle, is derived from cis-aconitate decarboxylation mediated by immune response gene 1 in mitochondrial matrix. Itaconate has emerged as a key autocrine regulatory component involved in the development and progression of inflammation and immunity. It could directly modify cysteine sites on functional substrate proteins which related to inflammasome, signal transduction, transcription, and cell death. Itaconate can be a connector among immunity, metabolism, and inflammation, which is of great significance for further understanding the mechanism of cellular immune metabolism. And it could be the potential choice for the treatment of inflammation and immune-related diseases. This study is a systematic review of the potential mechanisms of metabolite associated with different pathology conditions. We briefly summarize the structural characteristics and classical pathways of itaconate and its derivatives, with special emphasis on its promising role in future clinical application, in order to provide theoretical basis for future research and treatment intervention.
