Heat-Induced Changes in the Photochemical Centres and the Protein Secondary Structures of Photosystem II Studied by Variable Fluorescence and Difference FT-IR Spectroscopy
Authors: Joshi M. , Fragata M.
Published: August 2018

Variable fluorescence (Fv), i.e., Fv = Fm - F0 where F0 is the minimal fluorescence and Fm the maximum fluorescence, and difference Fourier transform infrared (FT-IR) spectroscopy were used to study the effect of heat stress in the 25-55 °C range on photosystem II (PSII) structure and function. First, the Fv intensity reflects accurately the changes in the number of open photochemical centers in PSII. Secondly, the use of Fv in combination with FT-IR spectroscopy can disclose structure-function correlations in the heat inactivation of the PSII complex. Analysis of the midpoint temperatures of thermal denaturation, i.e., 50% inactivation, reported so far in investigations of the thylakoid membrane components has revealed that most of the thermal transitions attributed to PSII are in the 39 -46 °C range. In this work, it is shown specifically that the midpoint temperature of PSII inactivation is at about 40 °C. Moreover, it was clearly demonstrated that the heat-induced changes above 40 °C are the result of a marked decrease in the number of open photochemical centers in PSII. It was also seen that above this same temperature the loss of photochemical centers has its structural counterpart in overall modifications of the secondary structures of the PSII proteins resulting from the decrease in the α-helix content concomitant with the increase in extended chain (β-strand) conformations. In brief, a novel finding reported here is that the number of open photochemical centers in PSII is dependent on a dynamic equilibrium between the contents of the PSII proteins in α-helix and extended chains (β-strands), but not in β-sheets and β-turn structures except for the antiparallel-β-sheet conformations. This therefore associates the thermal inactivation of the photochemical centers in photosystem II with distinct conformational changes in the proteins of the PSII supramolecular complex. In the particular context of the present study, these findings constitute a significant contribution to the investigation of structure-function correlations in the photosynthetic membrane. In a broader context, this information might be essential for the comprehension of the molecular arrangements or local structure order that are involved directly or indirectly in biological catalysis

Published: August 2018

Octanoic acid 2-hydroxymethyl-4-oxo-4H-pyran-5-yl ester (kojic acid 5-O-capryloate, 2), octanoic acid 4-oxo-2-(1-oxooctyloxymethyl)-4H-pyran-5-yl ester (kojic acid 5,7-di-O-di-capryloate, 3), and octanoic acid (5-hydroxy-4-oxo-4H-pyran-2-yl)-methyl ester (kojic acid 7-O-capryloate, 5) were prepared from 5-hydroxy-2-hydroxymethyl-4H-4-pyrone (kojic acid, 1) and caprylic acid. We also describe the synthesis of 11-aminoundecanoic acid (5-hydroxy-4-oxo-4H-pyran-2-yl)-methyl ester (6). In solution, the monoesters are non-competitive in­hibitors of mushroom tyrosinase (EC 1.14.18.1) (2: IC50 = 107 μM, 5: IC50 = 15 μᴍ, 6 : IC50 = 20 μᴍ; cf. 1: IC50 = 45 μᴍ, mixed type inhibition). When tyrosinase is immobilized in a polyvi-nylalcohol membrane, 5 is a weaker inhibitor than 1 or 2
Guanosine 3’:5’-Cyclic Monophosphate -Dependent Particulate Protein Kinase Activity from Yeast (Saccharomyces cerevisiae)
Authors: Eckstein Hans , Flügge Birgit
Published: August 2018

Continuing our studies on cGMP in growing yeast we detected a particulate cGMPdependent protein kinase (Pk-G), which was solubilized by detergents and NaCl. It achieves maximum activity at 25 °C and pH = 6.8, high concentrations of substrate proteins or cGMP produce saturation. Casein and histones are appropriate substrates, phosphatase-pretreated histone H-2a provokes outstandingly high activity. Pk-G differs from cAMP-dependent protein kinase (Pk-A) with respect to pH optimum, temperature tolerance above 50 °C, and stability. Partial purification is achieved by chromatography with DEAE-cellulose, Sepharose, and cGMP-substituted Sepharose. The latter step also markedly removes Pk-A. At least three proteins with Pk-G-activity and high cGMP-affinity are separated by polyacrylamide-gel-electrophoresis. Their apparent molecular masses, as deduced from comigrating marker proteins, differ considerably from those of other Pk-G’s, but also of Pk-A’s
On the Release of the Three Locust (Locusta migratoria) Adipokinetic Hormones: Effect of Crustacean Cardioactive Peptide and Inhibition by Sugars
Authors: Flanigan James E. , Gäde Gerd
Published: August 2018

An existing test to monitor the rate of adipokinetic hormone release from the corpora cardiaca (C C) of Locusta migratoria in vitro was improved, so that a constant basal rate of release was achieved and the amount of released Lom-AKH-I, II and III could be quantified by HPLC . This test system was subsequently used to demonstrate that a small peptide, which has been found in a few insect species including L. migratoria, crustacean cardioactive peptide (CCAP), induces release of all three AKHs. Moreover, 80 mᴍ trehalose reduces CCAP-induced release of AKHs in vitro, and 160 mᴍ glucose reduces this release even further. Glucose also had a greater inhibitory effect than trehalose on the spontaneous release and inhibited the high potassium-stimulated release of AKH from the CC in vitro. Eighty mᴍ sucrose, on the other hand, had no effect on the release of AKH . The effect of trehalose and glucose could be due to their use as an energy source, with trehalose first having to be converted to glucose. Whatever the stimulus, the three AKHs are released in the same proportions as they are found in the CC, which in vivo would make Lom-AKH-I, the most abundant AKH, the major effector of the biological effects of AKHs in adult locusts

Published: August 2018

Several species of freshwater green algae belonging to the order Zygnematales (Spirogyra crassa (Ktz.) Czurda, S. condensata (Vauch.) Czurda, S. longata (Vauch.) Ktz., S. juergensii Ktz., S. olivascens Rabenh. and Mougeotia viridis (Ktz.) Wittr.) were shown to have specific sterol content and characteristic monosaccharide composition of the biomass. Polysaccharide fractions were obtained by stepwise extraction of S. condensata and characterised by a determination of monosaccharides liberated after acid hydrolysis. Action of amyloglucosidase was used to prove the presence of starch in algal biomass. The main polysaccharide seems to be a complex mucilage composed of rhamnose, arabinose, xylose, galactose, and uronic acid, and the structure of this mucilage needs further investigation.
Synthetic Taxonomy of Rosa Races Using ACT-STATIS
Authors: Raymond Olivier , Fiasson Jean-Louis , Jay Maurice
Published: August 2018

Fifteen Rosa cultivated races were described by means of phenotypic frequencies (11 tables). Two groups of correlated contingency tables were identified by ACT-STATIS (Analyse Conjointe de Tableaux - Structuration de Tableaux à Trois Indices de la Statistique) interstructure analysis. Three data sets appeared to be independent from the others. Typologies of races were obtained after ACT-STATIS compromise analyses for the two groups of correlated tables, and after Principal Component Analyses for the independent data sets. Each typology was original and variously influenced by genealogical structure, mutation or artificial selection pressures. A weighted synthesis was attempted in order to build a taxonomy of races taking into account these diversity factors. The good agreement between the resulting classification and the assumptions about the history of Rosa domestication advocated for a wider utilization of ACT-STATIS and RV coefficient when the relationships between individuals or populations have to be studied on the basis of their similarities.
Suggested Pharmacophagy of the African Bushhopper Phymateus leprosus (Fabricius) (Pyrgomorphidae, Orthoptera)
Authors: Seibt Uta , Kasang Gerhard , Wickler Wolfgang
Published: August 2018

The bushhopper Phymateus leprosus (Fabricius) in the field shows a special appetite for the milkweed Asclepias fruticosa. Asclepiadaceae, like Apocynaceae and Scrophulariaceae, contain cardiac glycosides. Raw and purified extracts of these plants phagostimulate larval and adult P. leprosus. We also screened natural and half-synthetic compounds found in those plant extracts. While saponins and sapogenins did not stimulate the animals, many cardiac glycosides and aglycones, offered on filter paper, proved to be phagostimulants.
Seasonality of Leptin Levels in the BAT of the Common Shrew (Sorex araneus)
Authors: Nieminen Petteri , Hyvärinen Heikki
Published: August 2018

Leptin concentrations in the interscapular brown adipose tissue (IBAT) of the common shrew (Sorex araneus) were measured in different seasons. The leptin concentrations in IBAT were much higher than in the liver, where leptin is supposed to be of blood origin. In the heart muscle no detectable amount of leptin was found. There were clear seasonal variations in the leptin concentrations in IBAT. Leptin levels in IBAT were the lowest in November at the beginning of the winter. The concentrations increased, however, strongly after the onset of the permanent snow cover, and the highest concentrations were measured in December- January, when the weight of the animals was very low. In April-May, at the time when shrews attain sexual maturity, leptin concentrations in IBAT were lower than in the mid-winter, but significantly higher than in November. In overwintered adults the leptin concentrations were at the same level as in nonwintered subadults. Leptin originating from BAT may inform the central nervous system about the amount of nonshivering thermogenesis as well as the amount of feeding necessary for survival in the winter months.
Antifungal Effects of Hydrolysable Tannins and Related Compounds on Dermatophytes, Mould Fungi and Yeasts
Authors: Latté Klaus Peter , Kolodziej Herbert
Published: August 2018

A series of hydrolysable tannins and related compounds was evaluated for antifungal activities against filamentous fungi ( Epidermophyton floccosum; Microsporum canis; Microsporum gypseum: Trichophyton mentagrophytes; Trichophyton rubrum; Trichophyton tonsurans; Trichophyton terrestre; Penicillium italicum; Aspergillus fumigatus; Mucor racemosus; Rhizopus nigricans) and opportunistic yeasts ( Candida albicans; Candida glabrata; Candidata krusei; Cryptococcus neoformans), using the agar dilution method. While all samples had no activity against the filamentous fungi in concentrations of 1.1 -5.9 μм (1000 [μg/ml), the phenolic compounds displayed significant potencies against all the opportunistic yeasts tested but C. albicans, with minimum inhibitory concentrations ranging from 0.02 to 0.1 μм ( 16 - 125 (μg/ml). Although the presence of galloyl groups in flavonoids did not necessarily produce activity, this structural element, an HHDP moiety or its oxidatively modified entity proved to be an important structural feature of hydrolysable tannins. Comparison of dilution methods provided strong evidence of dependence of MIC values on the test method. Employing the microdilution broth method, the ellagitannin corilagin (MIC 0.8 nм) was found to be similarly potentially active as amphotericin B (MIC 0.5 nм) and sertaconazole (MIC 0.9 nм) against Candida glabrata strains. The order of effectiveness observed being 64- and 4 -8-fold increased for corilagin and the reference compounds respectively, when compared with that of the agar dilution test.
Aminophosphonate-Induced Changes of Betacyanine and Ionic Efflux
Authors: Grzyś Edward , Bielecki Krzysztof , Sarapuk Janusz
Published: August 2018

Betacyanine and ionic leakage from red beet (Beta vulgaris ssp. L. rapacea) roots and lilac (Syringa vulgaris L.) leaves under the influence of new aminophosphonates were studied by spectroscopic and conductometric methods. It was found that the leakage of dye or electrolytes depended both on the concentration of the compounds used and their structural features. The results compared to those obtained for the well known herbicide Buminafos® (dibutyl 1-butylamino-1-cyclohexanephosphonate) enabled to conclude that some of the compounds studied exhibited comparable or better activity than this herbicide. That makes them potentially good herbicides. It is possible that the effects observed are the result of action on cell membranes of the tissues used. The possible role of the structural features of aminophosphonates in this action is discussed.
Computer Simulations of the Electric Interactions between the Phospholipid Head-Groups and Ionic Admixtures in the Membrane Surface
Authors: Man Dariusz , Podolak Marian , Olchawa Ryszard
Published: August 2018

Some phospholipids (e.g. lecithin) form a system of electric dipoles on the membrane surface layer. In the case of lecithin the positive dipole charge is located on the choline and the negative one on the phosphoric molecule group. These dipoles are arranged almost parallel to the membrane surface. Taking the dipole membrane structure as a base for further investigations, a computer model of the electrostatic interaction between the dipole system and the ionic admixture was investigated. The model presumes hexagonal centered or a rectangular flat geometry of the 121 dipoles distribution. The dipoles may rotate freely around round the motionless symmetry axis perpendicular to the system surface. The initial state is given by fixing the geometry of the dipole matrix and ionic admixture distribution. Subsequently this system underwent a computer simulation which consisted of a calculation of resultant force moments acting on each dipole caused by other dipoles and ions. These force moments lead the system to the equilibrium state (minimum of the binding energy). The minimum energy value of the dipoles system depends on concentration and charge of the admixtured ions. The results of repeated simulations indicate that the system achieve the least of all binding energy (the most stable equilibrium state) at 1.5% concentration of admixtured ions in case of ion charge equal to 1Q (where Q denotes arbitrary unit of ion charge) and at 2.5% concentration of admixtured ions in case of ion charge equal to 2Q. The calculated results are in a good agreement with the experimental.
Composition of the Labial Gland Secretion of the Bumblebee Males Bombus pomorum
Authors: Valterová Irena , Urbanová Klára , Hovorka Oldřich , Kindl Jiří
Published: August 2018

Labial gland secretions of 22 males of the bumblebee Bombus pomorum , collected in the Czech Republic, were analysed separately for each individual. The secretions contained 70 compounds among which saturated and unsaturated hydrocarbons strongly dominated. The proportion of hydrocarbons in the secretion was unusually high (85-100% ) compared to other bumblebee species studied so far (3-15%). Methyl and ethyl esters of fatty acids, known from many other bumblebee species, formed only minor components (less than 1 % in sum) of the secretions of several B. pomorum individuals. No terpenic compounds, typical for males’ marking secretion of many bumblebee species, were detected in B. pomorum . The absolute quantities of hydrocarbons present in the labial gland extracts were comparable with those usually present in other species. The composition of hydrocarbons found in the labial glands was different from the profile of the cuticular hydrocarbons. Despite our expectations in species exhibiting a regular patrolling and scent-marking behaviour, the labial gland extracts obtained from B. pom orum males were unusually low concentrated and their chemical composition was atypical with respect of the proportions of hydrocarbons when compared with other patrolling species. This is the first report on the analysis of the labial gland secretion of the B. pomorum males.
Apuntes de poética narrativa. Florecimiento y ocaso de la novela histórica mexicana en el siglo XIX
Authors: Bobadilla Encinas Gerardo Francisco
Published: August 2018

La novela histórica fue el género literario dominante de la literatura mexicana entre 1836-1870, condicionada sin duda por la convulsa circunstancia histórica del país tanto como por la concepción de lo literario durante la época. Sin embargo, luego de la pacificación y consolidación de México a partir del orden y progreso positivista que desarrollaron la República restaurada (1967-1976) primero, el Porfiriato (1876-1911) después, la concepción y función de la historia y de la novela histórica en México se replantearon y dio inicio un proceso de declinación que condujo a su ocaso.

Por ello, el objetivo del presente trabajo está encaminado precisamente a describir e interrelacionar algunos de los distintos aspectos que marcaron el florecimiento y ocaso de la novela histórica dentro de la tradición literaria mexicana del siglo XIX, desde una perspectiva de estudio semiótica, integral, que busca apuntar dinámicamente al menos los elementos más destacados que participaron en el proceso.

Se destacan tres aspectos valisos del trabajo de investigación reseñado.1. El libro se ocupa de la farsa, un género desdeñado por la teoría y la crítica hispanoamericanas, pero que, sin embargo, es vigente y vital en nuestra tradición hispanoamericana.2. El estudio tiene un gran alcance de mirada para estudair la farsa. No se limita en el tiempo o la región, sino que busca trazos mucho más extensos para ubicar las tradiciones de las que la farsa es heredera.3. El trabajo es riguroso y especializado, pero está escrito con una prosa precisa y clara que permite, tanto a especialistas como a lectores en general, leer muy bien la obra y seguir las principales vetas de la farsa hispanoamericana.
Lengua(je)s, branding, e identidad en la Gran Cuba: Dreaming in Cuban de Cristina García
Authors: Aguilo Mora Francisca
Published: August 2018

Las metáforas conceptuales de puentes, fronteras, y otros espacios intermedios –las cuales forman lo que podríamos denominar ‘la ontología del guion’—prevalecen en las lecturas críticas de la producción artística de las hijas de la diáspora caribeña hispanófona en los EEUU. No obstante, en este artículo sostengo que las formas lingüísticas y los patrones discursivos que tienen lugar con frecuencia en estos textos no sugieren una carga de identidad lingüística ni el estado de hallarse entre lenguas y naciones, sino que crean una estética de la multiplicidad. A pesar de estar escritas mayoritariamente en inglés, estas obras se agrupan con una tradición literaria del Caribe hispanófono que cuestiona nociones estructuralistas de lengua e identidad, y perspectivas modernas de nación(alidad). En este artículo, expongo la necesidad de reconsiderar las conceptualizaciones de lengua y género en las construcciones de identidades locales, globales, y posnacionales en la Gran Cuba. Analizo cómo escritoras como Cristina García (y Achy Obejas, entre otras) reinterpretan la lengua a través de cruce lingüísticos, formando así una comunidad grancaribeña de práctica literaria que cuestiona los límites discursivos de las definiciones tradicionales de ‘lo americano’, ‘lo cubano’, ‘lo caribeño’, y lo cubano-americano’. Por medio de su branding lingüístico y sus componentes temáticos, estas novelas desestabilizan los imaginarios nacionales y archivos culturales predominantes tanto en la isla caribeña como en los EEUU, a la vez que problematizan el rol históricamente silenciado de las mujeres (escritoras), con un claro propósito de adquisición de poder.

A memória e os objetos: interpretações sobre o filme brasileiro “O palhaço”
Authors: Marchi Darlan De Mamann , Nery Olivia Silva
Published: August 2018

O filme “O Palhaço” (2011), do ator e diretor brasileiro Selton Mello, permite discutir algumas questões em torno da memória e da identidade. O palhaço circense Benjamin, protagonista do filme, e interpretado por Mello, sofre uma crise de identidade. Vivendo no espaço de um ofício tradicional sob a lona do circo, o personagem é afetado pela realidade de um mundo repleto de transformações. No documentário sobre a produção do filme, Mello fala da importância que teve um chapéu, utilizado pelo seu personagem Benjamin, para a concepção da obra. No roteiro da obra, quando vive seus dilemas, o palhaço materializa-os na metáfora de outro objeto: um ventilador. Estes objetos que compõem o universo do filme são os elementos que se utiliza, para a análise do mesmo nesse artigo.  Palavras-chave: palhaço; circo; memória; objetos; identidade.
O jardim dos refugiados
Authors: Coelho Rui Gomes
Published: August 2018

O presente artigo busca discutir o jardim como um objeto que permite problematizar a questão dos refugiados, campos de concentração, plantations escravistas e outras circunstâncias extremas do mundo moderno e contemporâneo. O autor argumenta que o jardim pode ser caracterizado como um tropo da modernidade em sua evocação de agência e liberdade, mas também de aprisionamento e violência. A arqueologia é percebida como um poderoso instrumento para trazer à tona e denunciar essa multiplicidade de sentidos, através das especificidades que o estudo da materialidade permite, levando-nos a questionar estereótipos de vitimização e afastamento.
BIONICS: An Out-of-School Day at the Zoo
Authors: Marth Michaela , Bogner Franz X.
Published: August 2018

Bionics by definition combines science and technology, with nature acting as a model for technical applications. Bionics is expected to lead to a better understanding of the Nature of Science (NOS). We applied a hands-on inquiry-based module about bionics with sixth graders during a public bionics exhibition in a zoological garden that allowed students to act as researchers, i.e., to understand the problem-solving process and to search for methods to overcome problems. The practice of science and engineering was at the center of this intervention; for example, students were asked to provide explanations and design solutions in the bionics field (NGSS, 2017). From this complex field we showed examples using living animals in the zoo. Our students learned bionics topics directly on the living animal by transferring them later to bionics topics. The streamlined shape of the dolphin snout, the communication system of dolphins, and other examples, each with its technical and bionics application, were examined. Bionics can serve as a complement to other biology topics. An increase in cognitive knowledge was observed both immediately after intervention and after a complete school year. Male participants showed more interest in technology than females.

A 14-year-old boy presented to our institution with a 1-month history of neurocognitive decline and intermittent fevers. His history was significant for fevers, headaches, and a 10-lb weight loss. Previous examinations by multiple medical providers were significant only for bilateral cervical lymphadenopathy. Previous laboratory workup revealed leukopenia, neutropenia, and elevated inflammatory markers. Despite improvement in his laboratory values after his initial presentation, his fevers persisted, and he developed slowed and “jerky” movements, increased sleep, slurred speech, delusions, visual hallucinations, and deterioration in his school performance. A brain MRI performed at an outside hospital before admission at our institution was concerning for patchy, increased T2 and fluid-attenuated inversion recovery signal intensity in multiple areas, including the basal ganglia. After transfer to our institution and admission to the pediatric hospital medicine team, the patient had an acute decompensation. Our subspecialists will discuss the initial evaluation, workup, differential diagnosis, definitive diagnosis, and subsequent management of this patient.

Laughter is an easily reachable way that can be used to erase barriers of communication for educational purposes. The purpose of this paper is to seek out students’ perception of humor added in teaching English and how that humor influenced students’ engagement in English classroom activity. This study employs research instrument of questionnaire and observation concepts through qualitative design. There are 78 students of multi-background: gender, level of intelligence and social background as research participants. These backgroundsareintended to obtain objective perception of the students. The findings revealed that the majority of students believed the teacher’s humor could prevent them from feeling stress of learning English, develop a better relationship between teacher and students, help them remember and understand the lesson, encourage them to be more active in the classroom and ease them in learning English. However there are some obstacles to overcome during humor application that apparently the English teachers need to build a good relationship and mutual trust with students and understand students’ interests, likes and dislikes prior to applying humor, so that the humor would be more likely to be welcomed and it would not cause emotional and psychological impact such as bullying and etc for the students.
ÜSTÜ KAR – ALTI BUZ: TÜRK TELEKOM’UN ÖZELLEŞTİRİLMESİ OLAYI
Authors: KALAYCI İrfan
Published: August 2018

Bu makalenin konusu ve amacı, Türk Telekom’un (TT) özelleştirme sorunsalını ve sonuçlarını diyalektik yöntemle incelemektir. Ekonomik küreselleşmenin aracı olan özelleştirme, post-kapitalist düzenin etkili bir aracıdır. Türkiye 24 Ocak 1980 İstikrar Proğramı ile birlikte liberal kapitalizmi benimseyerek özelleştirme ve kuralsızlaştırma kararlarını aldı. TT’nin özelleştirme süreci bu kararların bir eseridir. Bu özelleştirmede ekonomik değil ideolojik hareket edilmiştir, çünkü TT Türkiye’nin en kârlı kuruluşlarından birisi idi. TT’nin özelleştirilmesi ile IMF ve komprador burjuvazinin istediği neoliberal çark dönmüştür, fakat emekçi sınıfın aleyhine sınıfsal çatışma derinleşmiştir. TT’nin özelleştirilmesindeki hedefler ucuz ve yaygın hizmet, yabancı sermaye ile bütünleşme, rekabet ve verimlilik idi, ancak yüksek istihdam ve iyi ücretler hedefleri ihmal edildi. TT’nin özelleştirilmesi sonucunda devlet tekeli yerine özel tekel tehlikesine karşı düzenleyiciler devreye sokuldu ve böylece bürokrasi azalacağına daha da arttı. Özel TT Türkiye ve bölgesi açısından çeşitli jeo-ekonomik ve ekonomi-politik sonuçlar doğurdu. Bu sonuçların güçlü, zayıf, fırsatçı ve tehlikeli boyutu vardır. O yüzden burada bir GZFT çözümlemesi yapıldı.

Perakende sektörü tüm ekonomilerde çok önemli bir yere sahiptir. Birçok sektörde üretim firmalarının ve dağıtım kanalındaki diğer üyelerin hayatiyetlerini devam ettirebilmeleri perakende sektörünün sağlıklı bir şekilde işleyebilmesine bağlıdır. Türkiye’de özellikle son on yılda perakende sektörünün verimliği ile ilgili bir takım sorunların olduğu rekabette zorlandığı ve birçok performans göstergesinde gerilemelerin olduğu görülmektedir. Böyle bir dönemde perakende sektöründe discount (indirim) mağazacılık konseptinde 1995 yılından beri faaliyet gösteren, 2005 yılında halka açılan, 2017 yılı sonu itibariyle 6.765 mağaza sayısına ulaşan, perakende sektörünün çok önemli bir oyuncusu olarak sektörde adından sıkça söz ettiren BİM Birleşik Mağazacılık A.Ş.’ne daha yakından bakılması çok önemli veriler elde edilmesini sağlayacaktır.

Perakende sektörünün geleceğine ışık tutmak adına sektörün en önemli temsilcisi olan BİM Mağazalar zinciri ile Türkiye perakende sektörünün finansal performans göstergelerinin karşılaştırılması önemli tespitlerin yapılmasına zemin hazırlayacaktır. Perakende sektörü bu karşılaştırma verilerini dikkate alarak kendisini olumlu yönde revize edebilirse ülke ekonomisi açısından çok daha iyi konuma ulaşabilecektir.

Bu kapsamda 2011-2016 yılları arasında BİM Mağazalar zinciri ve Türkiye’de faaliyet gösteren perakende işletmelerinin finansal tablolarından faydalanılarak finansal performansları açısından bir farklılık olup olmadığı tespit edilmeye çalışılmıştır. Karşılaştırmalarda ayrıca üretim sektörü verilerine de yer verilerek perakende sektörünün durumu daha net belirlenmeye çalışılmıştır. Bu amaçla Türkiye’de faaliyet gösteren 2011-2013 yılları arasında 500 perakende işletmesi ve 3.506 üretim işletmesi, 2014-2016 yılları arasında ise 591 perakende işletmesi ve 3.057 üretim işletmesinin finansal tabloları incelenmiştir. BİM Mağazalar Zinciri finansal verilerine ise halka açık bir şirket olması dolayısı ile kendi internet sayfası yatırımcı ilişkileri bölümünde yayınladığı 2011-2016 yılları arasındaki finansal tabloları incelenmiştir. Çalışmanın amacı doğrultusunda elde edilen veriler oran analizi yöntemi ile analize tabi tutulmuştur. Analiz sonuçları uygulamalar bölümünde geniş şekilde ele alınmıştır.

Glocalização e mudança de identidade: missionários brasileiros pentecostais e carismáticos no Reino Unido
Authors: Burity Joanildo
Published: August 2018

Resumo Este trabalho analisa o processo de glocalização do pentecostalismo ou do evangelicalismo carismático brasileiro no Reino Unido, com base em entrevistas realizadas com missionários/as brasileiros/as, a partir de dois aspectos relacionados da sua experiência que estão alinhados com o que William Connolly chama de minoritização: um processo combinado de assertividade política e cultural e de subalternização (confinamento pós-colonial), que provoca transformações nas identidades pentecostais ou carismáticas diaspóricas. Procura-se, assim, fornecer um ponto de entrada para a compreensão dos meandros da relação entre cultura, fé e poder em contextos que, tendo sido fontes de expansão missionária da fé cristã, cada vez mais se tornam alvos de tentativas de “missões reversas” do Sul.
“... Ou Como Ter Ontological Blues”: notas sobre a vida no tempo da morte durante os bastidores de um axexê
Authors: Meira Thomás Antônio Burneiko
Published: August 2018

Resumo Este artigo remete a uma pesquisa mais ampla, acerca das agências de seres imateriais em uma casa de candomblé, na qual sou iniciado. O texto trata de uma crise vivenciada durante o rito funerário do axexê, quando fui “afetado” por intensidades provenientes do tempo dos mortos, e que, sob o aporte da “virada ontológica” na antropologia, me permitem ver o terreiro por influência de realidades distintas - a dos vivos e a dos falecidos -, e não pela pluralidade das visões do mundo. Sugiro, então, uma releitura da noção de anthropological blues, tanto para cobrir as afecções dos etnógrafos cujas análises extrapolam as premissas relativistas, mas também como possibilidade de se criar proposições teóricas em efetiva continuidade com as premissas nativas.
Nas Trilhas da Jurema
Authors: Grünewald Rodrigo de Azeredo
Published: August 2018

Resumo O nome jurema está associado a plantas, bebidas e até religiosidades específicas. Todas essas referências estão pautadas em fenômenos místicos, aqui percebidos em termos substantivos e históricos. Neste artigo, vamos examinar contextos de usos da jurema relativos, principalmente, aos indígenas, ao catimbó, à umbanda e ao psiconautismo neo-juremeiro pós-moderno. As tradições rituais serão examinadas de modo dinâmico e processual, mostrando seus entrelaçamentos culturais. Contrapor as tradições de conhecimentos exotéricos e esotéricos deverá também ser um esforço, principalmente ao se evocar a constituição de novas formas de uso ritual da jurema.

Resumo O pai e a mãe têm uma importância fundamental no desenvolvimento psicossocial dos filhos, bem como na regulação das emoções. Na pesquisa objetivou-se investigar o manejo dos pais frente à expressão da emoção raiva dos filhos do sexo masculino e feminino. Participaram 26 casais tendo dois filhos de seis a doze anos. Para coleta dos dados, utilizou-se questionário de dados gerais, Critério de Classificação Econômica Brasil, entrevista estruturada e história-estímulo. Verificou-se que as estratégias mais utilizadas pelos pais e mães frente à raiva dos filhos foram reação centrada no problema e reação punitiva, respectivamente estratégias, adaptativa e desadaptativa. Tanto os pais quanto as mães tenderam a reagir com minimização maior com o filho e reagir com distração maior com a filha. Conclui-se que pais e mães utilizam-se das mesmas estratégias mediante à expressão de raiva dos filhos de ambos os sexos, porém, há diferenças de gênero quanto à prática parental.
