Published: October 2018

Theoretical and practical issues of improving the quality of operational management of production processes through the implementation of MES (Manufacturing Execution Systems) are considered. To assess the risk of introduction of systems of this class, a basic set of seven influencing factors is defined. The qualitative approach to risk assessment proposes using two ordinal scales, on the basis of which the matrix for estimating the probability of occurrence of risk factors and the degree of their negative impact is built. The quantitative approach to risk assessment proposes using the formula for calculating the integral risk factor. The choice of the matrix organizational structure of management is justified in the realization of projects for implementation of MES at the enterprises with the innovative nature of production. Typical functional subsystems of MES implemented on the SIMATIC IT platform are identified and analyzed. Original express methods for evaluating the economic efficiency of investment projects for the introduction of MES are proposed. Practical testing of methodology is carried out through the example of evaluating the economic efficiency of the project for implementation of a MES at the enterprise with an innovative nature of production. As the results, relevant for the theory of building MES, the generalized algorithms of their functioning are proposed: the algorithm of operational planning of production processes with the use of a MES and the algorithm of the interaction of model functional modules in MES. The advantages of MES of new generation, i.e. management systems of combined production, are analyzed.

Objective: We aimed to compare surgical outcomes and postoperative complications among different hysterectomy approaches such as total abdominal hysterectomy, vaginal hysterectomy, multiport access laparoscopic hysterectomy, and single-port access laparoscopic hysterectomy.Study Design: This retrospective, single institution, case control study was carried out at the Obstetrics and Gynecology Department of Baskent University in Ankara, Turkey. We evaluated 86 consecutive patients who underwent hysterectomy for benign gynecological conditions.Results: A total of 86 women underwent hysterectomy: 20 (23.3%) total abdominal hysterectomy, 20 (23.3%) vaginal hysterectomy, 27 (31.3%) multiport access laparoscopic hysterectomy, and 19 (22.1%) single-port access laparoscopic hysterectomy using a transumbilical single-port system. There was no significant difference in uterine size between groups (Z=5.705; p=0.127). A statistically significant (p<0.001) difference in operation time (duration of surgery) was observed among the following groups. The duration of surgery for the multiport access laparoscopic hysterectomy, and single-port access laparoscopic hysterectomy groups was similar, with these two laparoscopic procedures requiring significantly more time than total abdominal hysterectomy and vaginal hysterectomy procedures. There was no statistically significant difference in between hemoglobin levels before and after operation between groups. There was no statistically significant difference between groups in intraoperative and postoperative complications. Six patients experienced complications, one intraoperative and five postoperative. Intraoperative complication was ureter injury in single-port access laparoscopic hysterectomy group. The postoperative complication rate was 5.8% (5 cases) in 86 patients. Perirectal abscess in one patient and wound infection in two patients occurred in total abdominal hysterectomy group (15%). Urinary tract infection in one patient and vaginal cuff cellulitis in one patient occurred in vaginal hysterectomy group (4%). No complications were reported in multiport access laparoscopic hysterectomy, and single-port access laparoscopic hysterectomy groups. Post-surgery, all patients who underwent single-port access laparoscopic hysterectomy reported that they were satisfied with their incision and cosmetic results.Conclusions: When technically feasible, multiport access laparoscopic hysterectomy, and single-port access laparoscopic hysterectomy may be performed instead f total abdominal hysterectomy because of rapid recovery and shorter hospitalization however there are longer operating time.

Objectives: There is not yet a consensus on the optimal surgical technique for cesarean section. This is the first study comparing two different (Cesarean Section) with respect to the following inflammatory reaction in means of changes in inflammatory marker levels.To evaluate the differences in inflammatory reactions following two different (Cesarean Section) techniques, the modified Misgav-Ladach versus the Pfannenstiel-Kerr technique.Study Desıgn: The study population included 88 pregnant women who met the inclusion criteria. These women were randomized into two groups according to Consolidated Standards of Reporting Trials guidelines: Group 1 (Misgav-Ladach group) and Group 2 (Pfannenstiel Kerr group). To compare the inflammatory reactions following surgery, Interleukin-6 (IL-6) and Tumor Necrosis Factor-α (TNF-α) levels were measured in venous blood samples drawn from the patients just before (0 hour) and 24 hours (24th hour) after the surgery. In 5 women from Group 1 and 2 women from Group 2, the 24th hour blood samples could not be obtained or were lost. Thus, a total of 81 women, 39 women from Group 1 and 42 women from Group 2, comprised the population of study. The differences in inflammatory reactions between the 0 and 24th hours were analyzed by calculating the percent change in IL-6 and TNF-α levels, and these percentages were then compared between the groups.Results: There was a statistically significant difference between Group 1 and Group 2 regarding the serum IL-6 level change between 0 and 24th hour (530±653% and 196±168%, respectively, p=0.022. The difference in TNF-α was also higher in Group 2, but the difference was not statistically significant (229±306% vs. 571±824%, p=0.12). The mean operation time was significantly shorter in Group 1 (9.44 min. vs. 16.86 min, p=0.0001).Conclusions: The results of this study indicate that the modified Misgav-Ladach technique has a weaker inflammatory reaction, which indicates fewer short- and long-term surgical complications.

Published: October 2018

Bioleaching has been demonstrated to be an effective technology for the removal of heavy metals and sludge dewaterability. Since bacteria gain nutrients by diffusion of soluble compounds, the insolubility of elemental sulfur may slow the growth of bacteria. Thus, it is very important to find an energy substance quickly become available to Acidithiobacillus thiooxidans. This paper studies the improvement of sludge dewaterability and heavy metal removal with sodium thiosulfate as the source of energy for Acidithiobacillus thiooxidans. Through orthogonal experiments with specific resistance to filtration (SRF) as the target index, four factors (FeSO4 dosage, Na2S2O3 dosage, sludge reflux ratio and sludge moisture content) were identified to be the important influencing parameters. The optimal conditions were: FeSO4 dosage, 8 g/L; Na2S2O3 dosage, 1.5 g/L; sludge reflux ratio, 30%; sludge moisture content, 97%. Results indicated that the SRF of the sludge decreased from 9.89 × 1012 to 1.03 × 1011 m/kg. The removal efficiencies of heavy metals Cu, Zn, Pb and Cr could reach 83%, 78%, 31% and 38% within 3 days, respectively. These results confirm the potential of sodium thiosulfate as an alternative energy substance in bioleaching to improve sludge dewaterability as well as removal of metals.

:

Aptamers are single-stranded DNA or RNA with 20-100 nucleotides in length that
can specifically bind to target molecules via formed three-dimensional structures. These innovative
targeting molecules have attracted an increasing interest in the biomedical field. Compared
to traditional protein antibodies, aptamers have several advantages, such as small size,
high binding affinity, specificity, good biocompatibility, high stability and low immunogenicity,
which all contribute to their wide application in the biomedical field. Aptamers can bind
to the receptors on the cell membrane and mediate themselves or conjugated nanoparticles to
enter into cells. Therefore, aptamers can be served as ideal targeting ligands for drug delivery.
Since their excellent properties, different aptamer-mediated drug delivery systems had been
developed for cancer therapy. This review provides a brief overview of recent advances in
drug delivery systems based on aptamers. The advantages, challenges and future prospectives
are also discussed.
Phenylboronic Acid-polymers for Biomedical Applications
Authors: Ryu Ji Hyun , Lee Gyeong Jin , Shih Yu-Ru V. , Kim Tae-il , Varghese Shyni
Published: October 2018

Background:

Phenylboronic acid-polymers (PBA-polymers) have attracted tremendous attention as potential stimuli-responsive materials with applications in drug-delivery depots, scaffolds for tissue engineering, HIV barriers, and biomolecule-detecting/sensing platforms. The unique aspect of PBA-polymers is their interactions with diols, which result in reversible, covalent bond formation. This very nature of reversible bonding between boronic acids and diols has been fundamental to their applications in the biomedical area.

Methods:

We have searched peer-reviewed articles including reviews from Scopus, PubMed, and Google Scholar with a focus on the 1) chemistry of PBA, 2) synthesis of PBA-polymers, and 3) their biomedical applications.

Results:

We have summarized approximately 179 papers in this review. Most of the applications described in this review are focused on the unique ability of PBA molecules to interact with diol molecules and the dynamic nature of the resulting boronate esters. The strong sensitivity of boronate ester groups towards the surrounding pH also makes these molecules stimuli-responsive. In addition, we also discuss how the re-arrangement of the dynamic boronate ester bonds renders PBA-based materials with other unique features such as self-healing and shear thinning.

Conclusion:

The presence of PBA in the polymer chain can render it with diverse functions/ relativities without changing their intrinsic properties. In this review, we discuss the development of PBA polymers with diverse functions and their biomedical applications with a specific focus on the dynamic nature of boronate ester groups.
Is very low LDL-C harmful?
Authors: Faselis Charles , Imprialos Konstantinos , Grassos Haris , Pittaras Andreas , Kallistratos Manolis , Manolis Athanasios
Published: October 2018

Background:

Low-density Lipoprotein Cholesterol (LDL-C) is a major Cardiovascular (CV) risk
factor. Accumulating evidence supports a linear association between LDL-C levels and CV risk. However, the
lower limit of LDL-C that might offer CV benefits without any safety concerns is still a topic of debate.

Objective:

The purpose of this review is to present the safety of reducing LDL-C to low levels as it comes from
major lipid-lowering drug studies, and to discuss data on several safety events that have been associated with low
LDL-C levels.

Methods:

A comprehensive literature search was performed to identify available data from clinical studies evaluating
the association of low LDL-C with safety outcomes.

Results:

Several large trials have evaluated the safety or reducing LDL-C to levels lower than 50 mg/dl or even
lower than 25 mg/dl, more commonly with the use of a combination of statins with ezetimibe or proprotein convertase
subtilisin kexin 9 inhibitors. In almost all trials, CV benefits were observed with LDL-C levels of 50
mg/dl or less compared with higher levels. In terms of safety, reduction of LDL-C to such levels was not associated
with any significant adverse event. Of importance, cancer and hemorrhagic stroke incidences were not increased
in patients attaining LDL-C lower than 40-50 mg/dl. Data regarding the impact of lowering LDL-C with
neurocognitive disorders are contradictory; nevertheless, most studies stand in favor of neurocognitive safety with
LDL-C reductions to low levels.

Conclusion:

Achieving an LDL-C of 40-50 mg/dl seems to be safe, and importantly might offer CV beneficial
effects. Data for attaining levels below 25 mg/dl is limited, however in favor of such reductions.
Effects of Achyranthes aspera Extracts on the Survival and Midgut Histo-architecture of Aedes aegypti L. Early IV Instars
Authors: Sharma Aarti , Kumar Sarita , Tripathi Pushplata
Published: October 2018

Background:

Aedes aegypti L.; one of the most important insect vectors in the world; transmits several diseases of concern; Zika, yellow fever, Chikungunya, dengue and dengue haemorrhagic fever. Despite multifarious problems on humans, non-targets and environment; caused by synthetic chemical insecticides; these are still the prime and preferred control measures against dengue vector. Alternative control strategies using eco-friendly and bio-degradable plant products are being explored.

Objective:

The present study investigates the toxic potential of the hexane extract of the leaf and stem of Achyranthes aspera against Ae. aegypti.

Methods:

The larvicidal potential of extracts was evaluated against dengue larvae as per WHO protocol. Subsequent concentration and time-dependent studies assessed their effects on the larval midgut histo-architecture using microtomy techniques.

Results:

Larvicidal bioassays with A. aspera extracts revealed their appreciable larvicidal potential. Hexane extract of the leaf resulted in respective LC30, LC50 and LC90 values of 67, 83 and 140 ppm while exposure to hexane extract of the stem showed respective values of 55, 68 and 115 ppm. Extract-exposed larvae at various lethal levels exhibited significant damage, shrinkage, distortion and vacuolization of gut tissues and peritrophic membrane. The disintegration of epithelial cells and cytoplasmic organelles evidenced stomach poison potential of the extracts. The extent of toxicity and damage was concentration and time-dependent; the stem extract imparted more deleterious effects as compared to the leaf extract.

Conclusion:

Present findings suggest the utilization of A. aspera as an alternate control strategy against Ae. aegypti; though further studies against non-targets are needed to ascertain its use in the fields.

Authors: Lédo Ana Paula , Rodriguez-Prieto Indira , Lins Liliane , Neto Mansueto Gomes , Brites Carlos
Published: October 2018

Background:

Poor functional status can significantly affect Health-Related Quality of Life (HRQoL) of HIV patients. However, there is scarce information on the functional profile of such patients before starting antiretroviral therapy (ART).

Objective:

To estimate the association between health-related quality of life and physical functioning in Antiretroviral-Naive HIV-infected patients.

Methods:

We conducted a cross-sectional study with HIV-infected patients older than 18 years, and naïve to antiretroviral therapy. The patients were evaluated for functional profile by pulmonary function (forced vital capacity, forced expiratory volume at one second, and Tiffeneau index), handgrip strength, and six-minute walk test in a cross-sectional study. HRQoL was evaluated by the 36-Item Short-Form Health Survey and its Physical (PCS) and Mental (MCS) Component Summaries. Multiple linear regression analyses were used to evaluate the association of predictor variables with PCS and MCS scores.

Results:

We found lower HRQoL among females patients, with far below average impairment of mental health component. Both male and female patients presented lower 6MWD function test values. Patients with dynapenia were older than patients without it, presented lower PCS mean score, lower family income, poor 6 MWD function test, lower FVC, and lower FEV1 t. Multivariable logistic regression analyses showed that Grip Strength, age and family income were predictor variables for Physical component of HRQoL. Female gender and smoking habit were predictive for the mental component of HRQoL.

Conclusion:

HRQoL in HIV, drug-naïve patients is predicted by level of dynapenia, smoking, income and gender. Therefore, lifestyle changes and active exercising can help to improve HRQoL in such patients.

Published: October 2018

The effect of planting density on the anatomical characteristics of wood is still matter of debate. The aim of the study was to investigate the influence of planting density on the variation of wood anatomical elements in Eucalyptus and Acacia trees cultivated in areas of high planting density (monospecific) and low planting density (mixed) stands. The fiber length, fiber width, fiber lumen diameter, cell wall thickness, vessel diameter and vessel frequency were evaluated. The measurements were made from wood discs taken from five Eucalyptus urophylla x E. grandis trees and five Acacia mangium trees grown in high planting density (monospecific plantations, 1667 trees/ha) and in low planting density (mixed stands, 500 trees/ha), totalizing 20 trees at 4.5 years old. Eucalyptus and Acacia produced wood with shorter fibers and smaller vessels in high density stands, when compared to its equivalent in low density. Acacia presented more frequent vessels and fibers with walls thicker than its equivalent in low planting density. Eucalyptus presented longer and thinner fibers and vessels more frequent than Acacia, regardless of planting density. On the other hand, in high planting density, Acacia presented fibers with walls thicker than Eucalyptus and in low density of planting their vessels were larger.
Do Relationship-Based Transactions Matter for Corporate Tax Avoidance? Evidence from China
Authors: DAI Bin , WANG Jingyuan , CHANG Huan
Published: October 2018

The existing literatures showing that relationship-based transactions would affect company tax avoidance, but with few empirical evidences. This paper makes an empirical study on the topic of relationship-based transations and corporate tax avoidence, by using the data of manufacturing companies from 2008 to 2016, in Chinese A-share listed market, the empirical study shows that the more relationship-based transactions with suppliers (clients), the more aggressive company tax avoidance, which indicates that the bahavior of company tax avoidance is influenced by business strategies. The study also shows that company’s financial decisions may contain selfish motives of powerful executives. Further, the study indicates that relationship-based transactions can boost company’s propensity for aggressive tax avoidance during fierce market competition. Yet, there are varying degrees of diversification in the moderating effects and weakening control rights by senior managers.
MODAL TRIGGERED NONLINEARITIES FOR DAMAGE LOCALIZATION IN THIN WALLED FRC STRUCTURES – A NUMERICAL STUDY
Authors: Rademacher Tobias , Zehn Manfred
Published: October 2018

This paper presents a novel method for detecting locations of damages in thin walled structural components made of fiber reinforced composites (FRC). Therefore, the change of harmonic distortion, which is found by current research to be very sensitive to delamination, under resonant excitation will be derived from FEM-simulation. Based on the linear modal description of the undamaged structure and the damage-induced nonlinearities represented by a nonlinear measure, two spatial damage indexes have been formulated.The main advantage of this novel approach is that the information about the defect is represented mainly by changes in the modal harmonic distortion (MHD), which just needs to be measured in one (or few) structural points. The spatial resolution is given by the pairwise coupling of the MHD with the corresponding mode shapes.

Published: October 2018

The article demonstrates that demands of modern ergonomics in man-machine combination mean scientific-based «machine» requirements as well as man-requirements since they limit reliability of whole system. Comparative study was held among operators (learning network), persons affected by asthenoneurotic syndrome, survey was carried out in private company. It has been discovered that besides usual procedure of job specification and recruiting it is necessary to assess dominating type of behavior, perception and information processing. Compatibility of the type with work requirements affects the effectiveness of mastering of profession and burnout and occupational health. This theory was tested in private company when developing quality management system using Expert system of human comprehensive analysis. Observation was held within six years. The result is that quantity of days because of illness reduced in 2,9 times. It can be said that this parameter is the objective index of human integration and properly developed quality management system in a company. The quality management system worked out in the base of Expert system of human comprehensive analysis allows to reduce burnout of personnel and keep up their occupational health. Basing on survey results the main profiles of operator performance were analyzed taking into account dominating type of behavior, perception and information processing. Thus psychophysiological predictors for potential naval operators were identified. This objective is relevant in naval construction of Russia.

Published: October 2018

This paper primarily aims to identify and evaluate the effect of Free Cash Surplus flows, Audit Quality and the ownership on Earnings Management. The study shows that financial distress has a significant impact on earnings management for samples on the Jordanian listed companies during (2003-2016). The Cash Flow Statement provides information on the flow of cash in and out of the organization over a specific period. It shows how an organization spends its money (cash outflows) as well as the source of the money (cash inflows). The Cash Flow Statement – additionally alluded to as the statement of cash flows or fund flows, which is one of the financial statements that is often utilized in the measurement of an organization’s financial performance and overall wellbeing. The study also investigates the prevalence of both accrual and base earnings management for the empirical corporate finance which claims that the better corporate governance constraints between earnings management and the relation of high free-cash -flows firms the more will the increase will be at the income management and the earnings management. Although, the research has addressed the issues of earnings management and the real activities handling; this research paper put these two issues together. The analysis provides a mixed support when using different earnings management detection models. The findings of this study could serve as a guideline to a proper and understanding of earnings management to public listed companies, regulators, and various stakeholders
Effects of working capital management policies on shareholders’ value: Evidence from listed manufacturing firms in Ghana
Authors: Adam Anokye , Quansah Edward
Published: October 2018

This study has sought to determine the effects of working capital management policies on shareholder value creation for six manufacturing firms listed at the Ghana Stock Exchange for the period of 2000-2013. Data were gathered from the annual reports of the firms and the publication of Ghana Stock Exchange. The study employed a longitudinal explanatory non-experimental research design applied to a dynamic panel Autoregressive Distributed Lags methodology framework for analysing the data. The results indicated that conservative current asset investment policies increase economic value added (EVA), whereas aggressive current asset investment policies enhance market-to-book ratio and Tobin?s Q in the long-run. On the other hand, conservative current asset financing policies enhance market-to-book ratio, Tobin?s Q, and EVA in the longrun. Thus, investors discount aggressive current assets? financing policies. A firm pursuing an aggressive current asset investment policy should balance it with a conservative current asset financing policy to create value for its shareholders.

Published: October 2018

No atual momento, quando se tornam prementes as mudanças nos programas que formam professores, o presente artigo traz para reflexão a discussão sobre os modelos de formação que orientam as propostas curriculares nos Cursos de Licenciaturas a partir da análise de uma experiência curricular com características de inovação desenvolvida na Universidade Federal do Paraná-Setor Litoral. Trata-se de uma pesquisa de abordagem qualitativa tendo como apoio a análise documental.  Autores como   Santos (2007), García (1999), Ávila (2008), Diniz-Pereira (2007) e Tardif (2011) deram suporte à construção do marco teórico conceitual com base nos modelos de formação propostos em seus estudos, a exemplo das orientações de cunho instrumental-tecnicista, epistemologia da prática e sociopolítica. Conclui-se que a experiência analisada se encaminha para um modelo crítico de formação que favorece a mudança em um conjunto de aspectos que se mostram vitais para uma revisão em cursos que prepararam os profissionais para a docência tais como: unidade entre teoria e prática na construção do conhecimento; integração entre universidade e escolas da educação básica num sentido de fortalecimento mútuo; articulação dos saberes em uma perspectiva de ruptura epistemológica que leva em consideração as experiências de vida de cada aluno e a constituição de novos espaços de aprendizagem para além dos muros da universidade, dentre outros.
Dorothy Hodgkin e seus estudos cristalográficos sobre a estrutura da penicilina
Authors: Prado Letícia Do
Published: October 2018

ResumoDorothy Crowfoot Hodgkin formou-se em química pela Somerville Oxford, doutorou-se em Cambridge e liderou o grupo de pesquisa que decifrou a estrutura molecular de várias moléculas biológicas complexas como: a penicilina, a vitamina B12 e a insulina. Seu nome não foi tão ovacionado quanto o de outros ganhadores do Prêmio Nobel já que seu método de trabalho, a cristalografia de raio X para a análise de moléculas complexas era ainda pioneiro e pouco disseminado entre os laboratórios da época. Foi a busca de soluções exatas para problemas difíceis que motivaram Dorothy a superar tempos de guerra, contratempos experimentais, demandas do casamento, da maternidade e a dor física persistente, para se tornar uma das maiores cientistas do século. Neste trabalho apresentaremos brevemente a vida de Dorothy, sua infância distante dos pais e rica em experiências culturais, sua juventude, as dificuldades que precederam sua entrada na Universidade e sua vida como pesquisadora, e mais especificamente, falaremos sobre sua colaboração para a solução da estrutura molecular da penicilina no cenário da Segunda Guerra Mundial. Nosso objetivo é apresentar ao leitor o trabalho de Dorothy ancorados em suas  publicações originais e suas biografias, de maneira a contribuir com a disseminação da história das mulheres na ciência. Palavras-chave: Dorothy Crowfoot Hodgkin; Penicilina; Mulheres na Ciência.AbstractDorothy Crowfoot Hodgkin graduated in chemistry from Somerville Oxford, doctorate from Cambridge and led the research group that deciphered the molecular structure of several complex biological molecules such as penicillin, vitamin B12 and insulin. Her name was not as ovation as that of other Nobel Prize winners since their method of working, X-ray crystallography for the analysis of complex molecules was still pioneering and little disseminated among laboratories of the time. It was the search for exact solutions to difficult problems that motivated Dorothy to overcome wartime, experimental setbacks, marriage demands, maternity, and persistent physical pain to become one of the greatest scientists of the century. In this work we will briefly present the life of Dorothy, her childhood far from her parents and rich in cultural experiences, her youth and the difficulties that preceded her entrance into the University and her life as a researcher, and more specifically, we will talk about her collaboration for the solution of molecular structure of penicillin in the scene of World War II. Our goal is to present the Doroty works, anchored in her original published and her biographies in order to contribute with the dissemination of history of women in science.Keywords: Dorothy Crowfoot Hodgkin; Penicillin; Women in Science.

Published: October 2018

The development of bioethanol as fuel substitution is believed to overcome the potency of the world energy crisis including Indonesia. The bioethanol development can be done by increasing the production capacity of the existing bioethanol factory plant by improving yeast culture for enhancing the performance of the fermentation process. This study was aimed at obtaining a method of optimizing the ability of Saccharomyces cerevisiae fermentation that can be applied by the alcohol industry in Indonesia for increasing factory productivity, thereby reducing the cost of producing alcohol. In this study, the adaptation of Saccharomyces cerevisiae Watei and Saccharomyces cerevisiae Hakken I were adopted in environment condition with high ethanol content up to 13%. The results showed that the yeast was able to grow in environments with high ethanol content with higher specific growth rate and larger cell size than those within the original yeast. This condition showed that adapted strains can overcome stress caused by high ethanol. These results promise the good performance yeasts with ability in growing and performing metabolic activities in high alcohol-containing environment conditions
El trabajo de alimentar: proceso alimentario entre trabajadores y trabajadoras agrícolas migrantes en Miguel Alemán, Sonora
Authors: Arellano Gálvez María del Carmen , Alvarez Gordillo Guadalupe del Carmen , Tuñón Pablos Esperanza , Huicochea Gómez Laura
Published: October 2018

El artículo analiza desde la perspectiva de género las prácticas del proceso alimentario entre migrantes pendulares y asentados en Miguel Alemán, Sonora. A partir de observaciones y entrevistas a profundidad a 21 migrantes, analizamos la relación entre el tipo de migración, estado civil, edad y tiempo de residencia en el lugar de destino. Para migrantes asentados, la participación de los hombres se relaciona con procesos de enfermedad y embarazo de las mujeres, mientras que los migrantes pendulares solos contratan servicios de comida, a pesar de que los más jóvenes saben cocinar. Concluimos que la participación de hombres en la alimentación es un cambio temporal, a nivel de prácticas y no cuestiona de fondo las normas hegemónicas de género.
Las imágenes de los cuatro continentes del escultor chileno Virginio Arias (1855-1941)
Authors: Morales Folguera José Miguel
Published: October 2018

En el siglo XVI queda establecida la iconografía de los cuatro continentes, que en los dos siglos posteriores sirven de inspiración para numerosos programas iconográficos. En el siglo XIX el academicismo vuelve a poner de moda estos modelos, que son imitados con algunas variaciones por artistas como el chileno Virginia Arias (1855-1941), que estudia y trabaja a finales del siglo XIX en París, donde realiza varias réplicas de los cuatro continentes, que hoy se encuentran en varios jardines españoles y americanos.
Caravaggio y Giordano Bruno: Modelos de disidencia y modernidad
Authors: López Flores Rafael Valentín
Published: October 2018

Caravaggio y Bruno fueron dos prohombres de los inicios del Barroco, y dado esto tratamos de cotejar aspectos de sus vidas y sus obras centrándonos en los puntos comunes que se establecieron respecto a dichos aspectos. Nos centramos para ello en lo que sus vidas y obras supusieron de modernidad y disidencia; tanto artística como filosófica, insertando dichas concomitancias dentro de la relación existente entre la pintura y la filosofía del Barroco.
El equilibrio entre la forma, el contenido y la función en el arte nuevo: Apuntes sobre la teoría artística y estética en Ramón Gómez de la Serna
Authors: Rueda Garrote Juan Francisco
Published: October 2018

El propósito de este artículo es mostrar la implicación de Ramón Gómez de la Serna en el debate crítico en torno a la conformación del arte moderno. Sus textos, con una fuerte carga teórico-atística y estética, ofrecen una visión mucho más compleja y enriquecida -por lo que de "escritura de taller" tienen- que otros considerados como canónicos para el acercamiento al fenómeno vanguardístico. Además, debemos poner en valor una obra que, desde 1909, sostenidamente, depara la actual visión que las últimas generaciones hemos heredado de las postreras revisiones a la primera mitad del siglo XX, es decir, una obra donde se equilibran lo formal, el contenido y la funcíón.
El color de la arquitectura imaginaria. Una aproximación a la literatura artística del Renacimiento
Authors: González Román Carmen
Published: October 2018

Frente al proyecto o la teoría arquitectónica de carácter técnico nos situamos en este estudio en el terreno de la descripción literaria, más o menos fantástica y no disciplinar. Desde la inmaterialidad e inconcreción de una arquitectura literaria, el color se nos presenta como un testimonio necesario de la capacidad creativa del ser humano más allá de los cánones preestablecidos. En este sentido, la arquitectura coloreada o colorista que hallamos en la literatura artística podría interpretarse como un elemento subversivo y claramente altemativo a la realidad inmediata, aunque en algunas ocasiones también supone una expresión fundada de frustrados anhelos.
La ambigüedad de la memoria: bases para la reconstrucción del color del Mercado de Mayoristas de Málaga
Authors: Coloma Martín Isidoro , García Gómez Francisco , Méndez Baiges Mª Teresa , Santana Guzmán Antonio
Published: October 2018

Ante la restauración del color en edificios de nuestro próximo pasado siempre dialogan dos referencias: la memoria de impresiones perceptivas y las deducciones de un análisis técnico y objetivo. Cuando ninguna de las dos referencias se puede manifestar de manera incuestionable, la adopción del criterio de restauración parece quedar liberado de imposiciones históricas. Ante esta posibilidad, concreta en la polémica del color desatada con motivo de la rehabilitación del antiguo Mercado de Mayoristas de Málaga para Centro de Arte Contemporáneo de la ciudad, en este articulo se analizan las posibilidades de deducción de criterios, y se propone adoptar los de carácter histórico-artístico hasta donde sean incuestionablemente conocidos dejando el libre albedrío en los restantes aspectos siempre y cuando estén presididos por la congruencia formal, histórica y social.

Málaga Republicana. Historia e Imágenes (1931-1936)
Authors: González Torres Javier
Published: October 2018

Se vanagloriaba Prometeo -en boca del dramaturgo Esquilo- de haber enseñado a los hombres griegos todas las ciencias, entre las que se encontraba la escritura, a la que definía como la memoria de la Historia. Quizás no reparó en que la libertad humana olvida a veces que cuando las crónicas se subvierten bajo principios proselitistas de marcada intencionalidad política, la importancia de los acontecimientos históricos suelen rebajarse a anecdóticas interpretaciones o a explicarse como trabas que impiden un determinado desarrollo, propiciando una premeditada anulación y olvido.
Crítica de exposición: "Extraversiones"
Authors: Royo Lourdes
Published: October 2018

Entre los días 7 de marzo y 27 de abril de 2003, la Sala Alameda albergó la exposición Extraversiones donde participaron artistas, en su mayoría mujeres, con el objetivo común de entablar un diálogo sobre cuestiones relacionadas con las obras artísticas, su función, el planteamiento de unos principios rectores en el mundo del arte o el papel que desempeña el público en el arte actual. Podríamos decir que nos encontramos ante un cambio generacional, pero realmente no sucede así, más bien podemos distinguir una actitud que pretende romper con el lenguaje artístico presente, protagonizado en este caso por artistas españolas.
Ramírez, Juan Antonio: Dalí: lo crudo y lo podrido
Authors: Méndez Baiges Maite
Published: October 2018

Empecemos por el final, pues de algún modo comprende todo lo demás. De las tres partes que componen Dalí: lo crudo y lo podrido, Juan Antonio Ramírez dedica la última a explicar y desvelar un método historiográfico al que él mismo propone bautizar con el nombre de iconológico-paranoico, una criatura nacida del cruce de los planteamientos de Panofsky con los de Salvador Dalí.
Rodríguez Marín, Francisco José. Descendimiento: 25 años de Historia. 400 años de Devoción
Authors: Ramírez González Sergio
Published: October 2018

El nuevo auge institucional y popular adquirido en los últimos años por la Semana Santa de Málaga ha suscitado, entre otras muchas cuestiones, la proliferación de estudios e investigaciones interdisciplinares sobre el tema. En este sentido, el arraigo y prevalencia en distintas épocas de tal celebración religiosa ha supuesto un amplio abanico de posibilidades a la hora de analizar sus aspectos antropológicos, sociales e histórico-artísticos.

Habituarse a otra tierra. Exilio con la Antigüedad. Erwin Walter Palm en Santo Domingo
Authors: Von Kügelgen Helga
Published: October 2018

Erwin Walter Palm (28/VIII/1910-7/VII/1988) filólogo y arqueólogo clásico, y su futura esposa Hilde Löwenstein (que sería conocida más tarde como la poetisa Hilde Domin) intuyeron el exterminio de los judios y dejaron en 1932 Heidelberg para seguir estudiando, doctorarse e investigar en Florencia y Roma. En 1939 tuvieron que irse a Inglaterra y en 1940 fueron a parar a la República Dominicana, en donde se quedaron 12 años. En Santo Domingo Palm descubre el Arte Colonial. Su conocimiento del mundo antiguo, medieval y moderno europeo  -orientación en lo inhabitual- desveló la recepción de Europa que se encerraba en lo colonial. A causa de Hitler, Palm se convirtió en uno de los pioneros de los estudios y de la conservación de los monumentos coloniales. Sus publicaciones siguen siendo el punto de partida de la investigación y restauración.
