Archaeology of Contemporary Migrant Journeys in Western Sicily
Authors: Blake Emma , Schon Robert
Published: January 2020

The Sicilian Channel between Sicily and North Africa receives global attention as a major migratory routefor undocumented people entering Europe clandestinely, a tragic nexus of transnational displacement anddesperation. While the plight of massively overloaded and unseaworthy boats of people justifiably receivesthe bulk of media attention, there is a less-observed movement that occurs and has occurred for thousandsof years: small boats expertly transporting handfuls of people back and forth across the Channel betweenTunisia and western Sicily. This study explores the material vestiges of cross-channel migrations throughassemblages identified during fieldwork by the Arizona Sicily Project along the southwest coast of Sicily inthe summers of 2018 and 2019. While the exigencies of maritime crossing require distinct technologies ofmobility, certain elements of migrant material culture are analogous to that found elsewhere, e.g. along theUS-Mexico border zone of Arizona's Sonoran Desert. Such elements include migrants' strategic triangulationof speed, invisibility and survival in deciding what to bring and the tactical triage of gear en route.Moreover, the political and economic injustices that are catalysts for the movements are comparable, as is thecriminalization of the migrants, which has done more to endanger than dissuade them. This article shedsnew light on migrant choices and challenges and contributes to the archaeology of contemporary migration.
Proportional hazards model under ranked set sampling scheme using censored data of coronary heart disease
Authors: KOYUNCU Nursel , ATA TUTKUN Nihal
Published: January 2020

The proportional hazards model is one of the most common model for analyzing survival data. Only proportional hazards assumption is required to apply this model. Using appropriate sampling methods is an important part of modelling data and estimation of parameters. In literature there is a few studies based on sampling methods in survival analysis and most of them are related with non-parametric estimations of survival functions, sample size calculation etc.  The main innovation of our approach is to examine the sampling methods for the proportional hazards model. This paper describes usage of ranked set sampling design in the proportional hazards model. In order to analyze the performance of our methods, we use a real data and conduct a simulation study. We conclued that ranked set sampling is more efficient than simple random sampling.

Published: January 2020

Abstract Introduction: Cerebral hydrodynamics complications in shunted patients are due to the malfunction of the system. The objective of this retrospective, single-center, single-arm cohort study is to confirm the safety and performance of Sphera® Duo when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cysts. Methods: Data were generated by reviewing 112 adult patient’s charts, who were submitted to a ventriculoperitoneal shunt surgery and followed for one year after surgery. Results: The results show us that 76% of patients had their neurological symptoms improved and that the reoperation rate was 15% in the first year following surgery. Discussion: Sphera Duo® shunt system is an applicable shunt option in routine neurosurgical management of hydrocephalus by several causes. It has presented good results while mitigating effects of overdrainage. Overdrainage is especially important in adults with non-hypertensive hydrocephalus and can cause functional shunt failure, which causes subnormal ICP (particularly in the upright position) and is associated with characteristic neurological symptoms, such as postural headache and nausea. Conclusion: Sphera Duo® shunt system is safe when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cyst.

Published: January 2020

Abstract Alzheimer’s disease (AD) is the most common cause of dementia. Despite numerous studies on the subject, the pathologies for AD are still unclear and there is still no ideal biomarker for diagnosis. The present study aimed to investigate clinical significance of human complement factor H (CFH) in patients with late-onset AD. Methods: The present prospective study included 187 late-onset AD patients who went to our hospital from January 2015 to December 2017. One hundred patients with mild cognitive impairment (MCI) and 80 healthy individuals who were age and gender matched to AD patients were enrolled as controls. Demographic data such as age, gender, and education duration were recorded. Blood samples were collected and serum levels of C-reactive protein (CRP), CFH, and brain-derived neurotrophic factor (BDNF) were determined by Enzyme-linked immunosorbent assay (ELISA). The mini-mental state examination (MMSE) score was measured for all patients. Results: No significant difference was found in age, gender, and education duration for all participants. The MMSE scores showed AD patients had lower MMES scores than the other two groups. All factors of CFH, CRP, and BDNF were dramatically decreased in AD patients compared with the MCI and the ealthy control. Levels of CFH were found to be positively correlated with levels of CRP; however, no significant correlation was found between CFH and BDNF, nor CFH and MMSE. Conclusion: CFH was decreased in late-onset AD patients, and serum levels of CFH was correlated with serum levels of CRP, but not MMSE and BDNF. These results may provide more clinical evidences for the role of CFH in AD patients.

Published: January 2020

RESUMO: Os níveis conceituais da escrita (FERREIRO; TEBEROSKY, 1999), revelam o processo evolutivo da compreensão do princípio alfabético pelas crianças. Por outro lado, as teorias sobre a aprendizagem da leitura revelam as estratégias de reconhecimento de palavras. Visando analisar a relação entre os níveis conceituais de escrita e as estratégias de leitura de palavras compostas por sílabas de estruturas CV, CCV e CVC, aplicou-se testes de leitura e de escrita de palavras em 47 crianças do 1º ano do Ensino Fundamental. Concluiu-se que a evolução da compreensão do princípio alfabético promovem avanços na leitura de palavras compostas por sílabas CV e a formação do léxico ortográfico; e que o confronto com as estruturas silábicas CVC e CCV contribui para que o sistema de análise sequencial das letras no reconhecimento da palavra se modifique, ampliando a percepção das crianças sobre a complexidade das estruturas fonológicas dos segmentos silábicos.

ABSTRACT: The purpose of this study was to select cold-tolerant sugarcane families and clones. Evaluations were carried out during three selection phases in the municipality of Pelotas, state of Rio Grande do Sul, Brazil. The experiments were arranged in an incomplete block design, with initially 4,452 seedlings of 53 full-sib families. Aside from the traits soluble solids content (BRX), tons of stalks per hectare (TSH) and tons of brixper hectare (TBH), the survival of the apical bud (ABS) was evaluated in the first selection stage (T1) of the breeding program. At the end of three selection phases, 15 clones of 14 of the 53 families evaluated in the first phase (T1) were selected for the experimental phase. Of these, the clones RS/PR126066, RS/PR126044, RS/PR126052, RS/PR126007 and RS/PR126033, had a good performance for apical bud survival in the first selection phase.

Published: January 2020

ABSTRACT: Nowadays, an important economic movement is involved in the improvement of polyethylene trays for the production of seedlings, being developed with different volumes, numbers and cell formats in an each culture-specific manner. The objective of the present study was to evaluate the performance of curly lettuce originated from seedlings from trays with different volumes, through the comparison between conventional and hydroponic-NFT cultivation. Five volumes of trays (10, 20, 30, 40 and 50 cm³ of cell-1) were tested in conventional and hydroponic cultivation, from February to March 2016. For the purpose of comparison, the plants were evaluated through the characteristics of height, circumference, stem diameter, number of leaves, fresh shoot mass and productivity. The use of volumes greater than 10 cm³ showed higher precocity in both cultivation systems, with hydroponic cultivation being more precocious and productive when compared to conventional cultivation.

Published: January 2020

Abstract: The knowledge about the richness and distribution of Brazilian dragonflies is still being unveiled. Over the years, inventories, reviews, and descriptions have been made. These contributions, apart from the taxonomic value, also provide valuable data on the occurrence of species and their distributions, which are rarely accompanied by notes about natural history and behavior. Keeping this legacy in mind, we collected dragonflies between 2011 and 2019 in Minas Gerais state, which resulted in the registration of 90 species, 41 genera and 11 families. Our results also increase distribution data, an important tool for conservation actions, and provide additional information about habitat and biology of species.
The influence of recession and macroeconomic variables on sectorial capital structure
Authors: Cardoso Vanessa Rodrigues dos Santos , Pinheiro Marília Cordeiro
Published: January 2020

Abstract The aim of this paper is to analyze the influence of the recent recession and of macroeconomic variables over the indebtedness in Brazilian industry sectors. The gap derives from the preference for investigating the reaction of capital structure according to economic sectors. However, it has to be considered that industry sectors react differently to variations in the economic context, since they have different optimal points of capital structure composition. The relevance of the chosen topic lies in carrying out a sectorial analysis of the effect of recession and of macroeconomic variables on capital structure composition, identifying the most sensitive sectors. It is also relevant in terms of being based on classical financial theories applied to the current context, in order to help predict the proportion of debt given fluctuations in a set of macroeconomic variables. Standing out among the main contributions of this article are the analysis of the level of indebtedness of Brazilian companies given the occurrence of recession and variations in the macroeconomy, identifying sectors that are most exposed to modifying their capital structure due to these factors. Six research hypotheses were formulated and tested using multiple linear regression, with two-stage fixed effects based on panel data collected from 211 companies, classified into six sectors, with data relating to the first quarter of 2010 up to the first quarter of 2018. The results revealed that the recent Brazilian recession was relevant for the capital structure of the sectors studied, with inflation only being significant for the health sector. The level of indebtedness of the basic materials sector was shown to be the most dependent on economic fluctuations and that of telephony and utilities was shown to be the least dependent. In addition, it was verified that the company-specific variables have greater relevance in determining capital structure compared to the macroeconomic ones.
Identifying outliers in asset pricing data with a new weighted forward search estimator
Authors: Aronne Alexandre , Grossi Luigi , Bressan Aureliano Angel
Published: January 2020

ABSTRACT The purpose of this work is to present the Weighted Forward Search (FSW) method for the detection of outliers in asset pricing data. This new estimator, which is based on an algorithm that downweights the most anomalous observations of the dataset, is tested using both simulated and empirical asset pricing data. The impact of outliers on the estimation of asset pricing models is assessed under different scenarios, and the results are evaluated with associated statistical tests based on this new approach. Our proposal generates an alternative procedure for robust estimation of portfolio betas, allowing for the comparison between concurrent asset pricing models. The algorithm, which is both efficient and robust to outliers, is used to provide robust estimates of the models’ parameters in a comparison with traditional econometric estimation methods usually used in the literature. In particular, the precision of the alphas is highly increased when the Forward Search (FS) method is used. We use Monte Carlo simulations, and also the well-known dataset of equity factor returns provided by Prof. Kenneth French, consisting of the 25 Fama-French portfolios on the United States of America equity market using single and three-factor models, on monthly and annual basis. Our results indicate that the marginal rejection of the Fama-French three-factor model is influenced by the presence of outliers in the portfolios, when using monthly returns. In annual data, the use of robust methods increases the rejection level of null alphas in the Capital Asset Pricing Model (CAPM) and the Fama-French three-factor model, with more efficient estimates in the absence of outliers and consistent alphas when outliers are present.
A flâneuse na literatura brasileira: espaços e temporalidades contestados
Authors: Brandellero Sara
Published: January 2020

Resumo A questão do espaço, e sua “produção”, conforme Lefebvre (1974), vem se revelando uma rica área de pesquisa para os estudos literários, assim como as questões ligadas à mobilidade em suas diferentes realidades: de experiências de migração e diáspora a trânsitos urbanos, para citar alguns exemplos. Nesse contexto, a figura do flâneur, intrinsicamente ligada às experiências e representações da modernidade urbana, tem atraído considerável interesse crítico. Em geral, pouco explorada ainda é a figura de seu equivalente feminino, a flâneuse, pois, como bem observa Wolff (1985), a experiência da modernidade tem sido, em grande parte, narrada sob um ponto de vista predominantemente masculino. A partir do conto “Amor”, de Clarice Lispector (1960/1998), e o texto “Um corpo negro pelado”, de Miriam Alves (2014), este artigo discute como esses textos parecem dialogar com o paradigma da mobilidade moderna, analisando personagens femininas em trânsito na literatura brasileira contemporânea escrita por mulheres como tentativas de repensar a experiência desta mobilidade, agora como um ato político e de busca de empoderamento feminino.
A regional similarity-based approach for sub-daily rainfall nonparametric generation
Authors: Aguilar Milena Guerra de , Costa Veber Afonso Figueiredo
Published: January 2020

ABSTRACT Rainfall time series with high temporal resolution are required for estimating storm events for the design of urban drainage systems, for performing rainfall-runoff simulation in small catchments and for modeling flash-floods. Nonetheless, large and continuous sub-daily rainfall samples are often unavailable. For dealing with the limited availability of high-resolution rainfall records, in both time and space, this paper explored an alternative version of the k-nearest neighbors algorithm, coupled with the method of fragments (KNN-MOF model), which utilizes a state-based logic for simulating consecutive wet days and a regionalized similarity-based approach for sampling fragments from hydrologically similar nearby stations. The proposed disaggregation method was applied to 40 rainfall gauging stations located in the São Francisco and Doce river catchments. Disaggregation of daily rainfall was performed for the durations of 60, 180 and 360 minutes. Results indicated the model presented an appropriate performance to disaggregate daily rainfall, reasonably reproducing sub-daily summary statistics. In addition, the annual block-maxima behavior, even for low exceedance probabilities, was relatively well described, although not all expected variability in the quantiles was properly summarized by the model. Overall, the proposed approach proved a sound and easy to implement alternative for simulating continuous sub-daily rainfall amounts from coarse-resolution records.
Parametric study of the compaction effect and the response of an oscillation roller
Authors: Paulmichl Ivan , Adam Christoph , Adam Dietmar
Published: January 2020

This paper examines the influence of different model and operating parameters of an oscillation roller on the compaction effect and the response behaviour. The main objective is the validation of a recently established continuous compaction control parameter for oscillation rollers. The study is based on a numerical model of the dynamic roller–soil interacting system, in which the intergranular strain enhanced hypoplastic constitutive model is implemented to predict the achieved soil compaction more realistically. The computed drum acceleration is compared with data recorded in field tests. One result is that the roller speed has a significant effect on the soil compaction achieved. The outcomes of this study confirm that the quantities derived from the drum response are basically suitable as indicators for continuous compaction control with oscillation rollers.
Moving from building information models to digital twins for operation and maintenance

Published: January 2020

With the rising adoption of building information modelling (BIM) for asset management within the architecture, engineering and construction sectors, BIM-enabled asset management during the operation and maintenance phase has been increasingly attracting more and more attention in both research and practice. This paper provides a comprehensive review and analysis of the development of state-of-the-art research and industry standards that impact on BIM and asset management within the operation and maintenance phase. However, in the aspects of both information richness and analytical capability, BIM is not always enough in delivering effective and efficient asset management, particularly in the operation and maintenance phase. Therefore, a framework for future development of smart asset management is proposed, integrating the concept of digital twins. Digital twins integrate artificial intelligence, machine learning and data analytics to create dynamic digital models that are able to learn and update the status of the physical counterpart from multiple information sources. The findings will contribute to inspiring novel research ideas and promote widespread adoption of digital-twin-enabled asset management within the operation and maintenance phase.

Galectin-1 reduces the severity of ulcerative colitis induced by dextran sulfate sodium via suppressing inflammatory and oxidative mediators
Authors: Arda-Pirincci Pelin , Aykol-Celik Guliz
Published: January 2020

Ulcerative colitis is an inflammatory bowel disease and many people suffers from this disease across the word. Dextran sulfate sodium (DSS) is a synthetic sulfated polysaccharide that is used to produce ulcerative colitis in rodents. Galectin-1 is a β-galactoside binding animal lectin which plays key roles in many biological events. In this study, we investigated the role of galectin-1 on colon morphology, cell proliferation, oxidative stress, anti-oxidant system, inflammatory and anti-inflammatory mediators in the model of experimental ulcerative colitis induced by DSS in mice. C57BL/6  mice were fed orally 3% DSS in their drinking water for 5 days for acute colitis induction. Animals were injected with 1 mg/kg recombinant human galectin-1 for 7 consecutive days. Oral DSS application resulted in colitis injury by causing histopathological changes; an increase in disease activity index (DAI), lipid peroxidation (MDA), myeloperoxidase (MPO) and TNF-α levels; a decrease in body weight, colon length, cell proliferation index, catalase (CAT), glutahione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities, gluathione (GSH) and IL-10 levels. However, treatment with galectin-1 prevented DSS-induced colitis injury through the reduction of DAI, MDA, MPO and TNF-α levels, and the increase of body weight, colon length, cell proliferation, antioxidant enzymes activities, GSH and IL-10 levels. As a result, this study showed that galectin-1 has proliferative, anti-oxidant, anti-inflammatory, and cytoprotective effects against DSS-induced colitis in mice. In addition, galectin-1 reduces the severity of ulcerative colitis via suppressing inflammatory and oxidative mediators.
¿Por qué AICLE? Un análisis de la literatura desde la perspectiva de los docentes de materias no lingüísticas
Authors: Porcedda Maria Elisabetta , González-Martínez Juan
Published: January 2020

Desde su nacimiento en 1994 hasta ahora, el modelo AICLE (Aprendizaje Integrado de Contenidos y Lenguas Extranjeras) ha sido conceptualizado e implementando de diferentes modos, según las políticas de los diferentes gobiernos, o de las escuela, o de las propias actitudes de los docentes interesados, lo que ha causado un margen de vaguedad en su definición. Esto es muy importante, ya que la adopción de CLIL por parte de la Unión Europea para apoyar el objetivo del multilingüismo se ha centrado en los resultados lingüísticos en varios niveles y, por lo tanto, en las investigaciones y encuestas llevadas a cabo; sin embargo, las pràcticas CLIL las implementan principalmente docentes de asignaturas no lingüísticas, que necesitan ver la efectividad de su perspectiva, no solo desde el lingüístico. Este documento revisa la literatura y encuentra la definición de CLIL como "entorno abierto de educación", definitivamente adecuado para los profesores de cualquier asignatura no lingüística para poder participar en su implementación. También se subraya, teniendo en cuenta las directivas europeas, cómo el CLIL, en particular si se enseña a través de herramientas ofrecidas por las nuevas tecnologías, tiende a facilitar el aprendizaje global de los estudiantes y su ciudadanía europea, así como a ser el primer paso para uno nuevo modelo de práctica escolar.

Published: January 2020

Cerebrovascular reactivity and cerebral autoregulation are two major mechanisms that regulate cerebral blood flow. Both mechanisms are typically assessed in either the supine or seated postures, but the effects of body position and sex differences remain unclear. This study examined the effects of body posture (supine vs. seated vs. standing) on cerebrovascular reactivity during hyper and hypocapnia and on cerebral autoregulation during spontaneous and slow-paced breathing in healthy men and women using transcranial Doppler ultrasonography of the middle cerebral artery. Results indicated significantly improved cerebrovascular reactivity in the supine compared with seated and standing postures (supine= 3.45±0.67, seated= 2.72±0.53, standing= 2.91±0.62%/mmHg, P<0.0167). Similarly, cerebral autoregulatory measures showed significant improvement in the supine posture during slow-paced breathing. Transfer function measures of gain were significantly decreased and phase significantly increased in the supine posture compared with seated and standing postures (gain: supine= 1.98±0.56, seated= 2.37±0.53, standing= 2.36±0.71%/mmHg; phase: supine= 59.3±21.7, seated= 39.8±12.5, standing= 36.5±9.7°; all P<0.0167). In contrast, there were no effects of body posture on cerebral autoregulatory measures during spontaneous breathing. Men and women had similar cerebrovascular reactivity and similar cerebral autoregulation during both spontaneous and slow-paced breathing. These data highlight the importance of making comparisons within the same body position to ensure there is not a confounding effect of posture.
Corporate Social Responsibility in the Agri-Food Sector: Evidence from Greece

Published: January 2020

Corporate Social Responsibility (CSR) can benefit business directly, such as by improving the working environment and increasing productivity, and indirectly, such as by increasing customers’ interest and sales. The focus of this article lies on the investigation of CSR in the Greek agri-food companies through two perspectives, namely the business and the consumer perspective. The business perspective is based on the investigation of CSR activities promoted on the corporate websites of 222 food companies, SMEs and large sized. The consumer perspective is based on a questionnaire analysis of 200 participants, investigating their willingness to purchase products from companies practicing CSR activities. The results of this research showed that CSR activities are rather low in Greece and only few agri-food companies’ have a clear and sound strategy to promote such actions. It seems that, during the economic crisis, most companies, especially SMEs, do not invest in such activities, but their main concern is survival, which -given the economic environment- is challenging. In addition, companies mainly support social activities, give less support to environmental activities, and even less support to human resource activities. Although most consumers seem to be socially aware of the CSR actions performed by the agri-food companies and have a sense of responsibility themselves, a significant part still is unaware of such actions.

AbstractThe objective of this work was to analyze scientific evidence from a literature review pertaining to the effectiveness of resinous infiltrants for minimally invasive treatment of incipient carious lesions. Studies published between 2002 and 2019 were queried from the following databases: Capes, PubMed, Medline, BBO, Lilacs and SciELO. The search keywords included "Dental Caries", "Tooth Remineralization", "Dental Leakage". Most of the studies found resin-infiltrating treatment to be a viable option for the minimally invasive treatment of incipient carious lesions; this treatment was able to fulfill the primary expected effects: inhibition of carious progression and the lesions esthetic improvement. However, some issues need to be clarified to improve the safety of this treatment because it can be recommended in clinical practice. In conclusion, the use of resinous infiltrants has been reported as promising for the treatment of incipient carious lesions. However, there is a need for long-term studies to confirm the effectiveness of this treatment to determine its applicability for clinical use. Keywords: Dental Caries. Dental Leakage. Tooth Remineralization. ResumoO objetivo desse trabalho foi analisar evidências científicas, por meio de uma revisão de literatura, sobre a eficácia do uso de infiltrantes resinosos para o tratamento minimamente invasivo de lesões cariosas incipientes. A seleção do material literário utilizado foi realizada por pesquisa sobre o tema nas bases de dados: portal de periódicos Capes, PubMed, Medline, BBO, Lilacs e SciELO, abrangendo prioritariamente, o período de 2002 a 2019. Para busca nas bases de dados foram utilizadas palavras-chave como “Cárie Dentária”, “Remineralização Dentária”, “Infiltração Dentária”, assim como suas correspondentes na língua inglesa.  A maioria dos estudos encontrados aponta o tratamento infiltrante resinoso como uma opção viável para o tratamento minimamente invasivo de lesões cariosas incipientes sendo capaz de cumprir os principais efeitos esperados: inibição da progressão cariosa e melhoria estética das lesões. Entretanto, alguns impasses necessitam ser esclarecidos para que o tratamento seja recomendado com mais segurança na prática clínica. Conclui-se que o uso de infiltrantes resinosos tem sido relatado como promissor para o tratamento de lesões cariosas incipientes, contudo há necessidade de novas pesquisas e estudos a longo prazo para confirmar sua eficácia em todos aspectos desejáveis para seu uso clínico. Palavras-chave: Cárie Dentária.

Análisis psicosocial del prejuicio hacia trabajadoras sexuales
Authors: Imhoff Débora , Dreizik Matías , Brussino Silvina
Published: January 2020

This study analyzed the psycho-social and psycho-political variables that contribute to predict prejudice towards sex workers (PSW). A two-phase quantitative study with university students was carried out: phase one included an instrumental research oriented to the construction and evaluation of a scale of PSW; phase two consisted of an ex post facto study with simple retrospective design. After ratifying the psychometric qualities of the constructed scale, a multiple regression analysis was performed. In both PSW dimensions, authoritarianism and opposition to equality were two of the variables that most contributed to the prediction. Also, religion and ideological self-placement were included in the models.
Escala geográfica: visibilidades e invisibilidades en procesos culturales afrodescendientes (suroccidente de Colombia)
Authors: Mosquera-Vallejo Yilver
Published: January 2020

The scale is a highly contingent and fluid socio-cultural construction, which makes possible, in terms of spatialized articulations, to think of multiple cultural, social, and territorial processes at different spatial levels. The purpose of this manuscript is to analyze the recovery processes of cultural traditions in the Patía Valley initiated in the 80s until 2018, based on the conceptualization of geographic scale as a network. To accomplish this, we carried out a semi-structured interview with a social actor that has accompanied the recovery of traditions from the beginning. This, with the aim of understanding, from their experience, how the cultural processes developed in Patía have been articulated through multiple scalar networks, connected and interacted through visibility and invisibility geographical practices. This led us to establish that geographic visibility is linked to delocalized practices, while geographical invisibility is defined as “place-based” practice.
Más acá de la negritud: negrismo y negredumbre como categorías de reconocimiento en la primera mitad del siglo XX latinoamericano
Authors: Oliva María Elena
Published: January 2020

This article analyzes how Black/Afro-descendant intellectuals have used negrismo and negredumbre as self-classifying categories of identity during the first half of the 20th century in the Spanish-speaking areas of Latin America. The study allows us to draw a comparison with negritude, one of the most popular categories in current scholarly work, but which, as a concept and movement of cultural affirmation, only entered Black/Afro-descendant intellectual discussions in Latin America in the 1970s. Reviewing these discourses helps comprehend that negritude was considered a foreign concept, with different socio-historical tensions, and that within Latin America, Black/Afro-descendants had already adopted other concepts to classify their own identity.
“Quítate de mi escalera, no me hagás oscuridad”: imágenes de lo “negro” en la antropología colombiana 1930-1970
Authors: Hurtado-Garcés Rudy Amanda
Published: January 2020

This reflection article proposes to make an archaeological excavation of five decades (1930-1970) in the history of the anthropological discipline in Colombia in order to expose, in an exploratory way, the different ethnographic views on the “other-black”. This research was conducted through the contrapúntal historical archaeology, a theoretical-methodological proposal that involves discussing two or more interpretative perspectives, ways of looking, translating and representing that dispute the file, the locus of enunciation and the senses of the same category. In this regard, the narratives, translations, and representations that produced the Colombian anthropology on that “other-black” are visited, delving into the work of La minería del hambre: Condoto y la Chocó Pacífico (1971) from the Caribbean anthropologist Aquiles Escalante. Thus, it will be demonstrated, the regime of truth, the criteria of hierarchy, exclusion and the colonial and racist valuation that operate within the Colombian anthropological field in its epistemic and praxiological indissoluble horizons.
Literatura de patíbulo en el siglo XIX colombiano. La restauración de las conductas
Authors: Rubio Alfonso
Published: January 2020

This article aims to approach the role that these writings maintained during the nineteenth century in the context of a rising republican regime and its judicial system from a methodology of documentary analysis focused on representative samples that originated in the public execution of those sentenced to death on the gallows. In the terminology proposed by Hans-Jürgen Lüsebrink we have categorized them as "Gallows literature" which, in its varied range of forms such as court judgments or farewell letters, provided stories concerning the defendant sentenced to death and the rituals of execution conceived as mechanisms of the State that strengthened its capacity to exercise justice. The executive judgments showed a language that has allowed us to compare them with the moralizing message, whose purpose had to do with the restoration of the behaviors, the romances of Spanish crimes since the literary origin and intentions are similar.

Background: Studies show that in India, the health loss from alcohol will grow larger, unless effective interventions are implemented. Initiation of alcohol intake starts from a very early age and is higher in rural areas. The best way to reduce alcoholism is prevention rather than curing the already addicted persons. For this we need to know the magnitude of this problem. This study is aimed at estimating the prevalence, identifying the causative and contributing factors of alcoholism among higher secondary school children of Theni district.Methods: A self-administered validated questionnaire was given to the male school students of 15 to 17 years (XI and XII students) to assess the prevalence and pattern of alcohol use among them. The questionnaire was prepared with reference from the global school-based student health survey (GSHS), the alcohol use disorders identification test (AUDIT) questionnaire and the cut-annoyed-guilty- eye (CAGE) questionnaire. Data analysis was done using software OpenEpi, Version 3.Results: A total of 500 students were analyzed with a response rate of 94% (n=470). The overall prevalence of alcohol use was found to be 31.06%. Nearly 70% had the possibility of alcoholism and should be investigated further for severity of alcohol use, 30% had impaired control over drinking almost daily and 17% had injury or injured someone because of drinking.Conclusions: The mean age of initiation of alcohol consumption is decreasing and the number of alcohol consumers is increasing.
