A Research Framework for Business Models: What Is Common Among Fast Fashion, E-Tailing, and Ride Sharing?
Authors: Cachon Gérard P.
Published: August 2019

Every firm has a business model, which is the collection of strategic decisions that determine how the firm generates a sustainable enterprise through the creation of enough value (its supply model) and the extraction of a sufficient portion of that value (its revenue model). Innovative business models—for example, fast fashion (e.g., Zara), e-tailing (e.g., Amazon), and ride-sharing (e.g., Uber)—are capable of offering new products and services that generate considerable consumer utility and transform industries. This paper develops a research framework for understanding business models and how business models have evolved over time. Links are made to the existing literature (primarily in pricing and operations), and simple models are developed to unify and clarify existing research findings. Through this framework, it is possible (i) to identify the few design decisions that explain the success of these diverse firms with otherwise seemingly disparate models, and (ii) to speculate on potential future business-model innovations.

Modeling Payment Timing in Multiechelon Inventory Systems with Applications to Supply Chain Coordination
Authors: Tong Jordan , DeCroix Gregory , Song Jing-Sheng
Published: August 2019

Problem definition: How can one adapt multiechelon inventory models to capture the cash flows generated by various payment-timing contracts? What competitive inventory policy behavior arises under these various payment-timing arrangements? Academic/practical relevance: Technology advancements are increasing the variety of payment triggers between supply chain stages. However, traditional multiechelon inventory models, which were originally developed for vertically integrated systems, do not explicitly account for payments flowing up the supply chain nor issues of payment timing between stages. Methodology: We introduce an analytical modeling methodology to incorporate financial inventory costs generated by payment-timing arrangements between stages in multiechelon inventory models. We also combine these methods with established inventory theory to study competitive inventory policies in a two-echelon system. Results: Under a class of payment-timing contracts, we show how to express payment flows at each stage in terms of standard physical inventory metrics and the demand-arrival process. We also show how to calculate the average inventory costs for each stage under given inventory policies and payment-timing contracts. In the two-echelon base-stock model, we first show that the cost of decentralization under standard wholesale price contracts is significantly driven by too much inventory at the supplier; it is not exclusively driven by too little inventory at the retailer as in the selling-to-the-newsvendor literature. We show that wholesale price contracts with a type of popular consignment payment timing still leads to too little inventory at the retailer. However, we prove there exists a wholesale price contract with partial consignment timing that can achieve the centralized inventory levels at both the supplier and the retailer. Managerial implications: Researchers can leverage our methodology to incorporate the price transfers and timing aspects of contracts in multiechelon inventory models. Our insights also help managers better understand the impact of prices and payment timing on decentralized chain behavior and performance.

Economic growth in many countries is increasingly driven by successful startups that operate as online platforms. These success stories have motivated us to define and classify various online platforms according to their business models. This study discusses strategic and operational issues arising from five types of online platforms (resource sharing, matching, crowdsourcing, review, and crowdfunding) and presents some research opportunities for operations management scholars to explore.
Contribuições para o aperfeiçoamento do regulamento MERCOSUL sobre etiquetagem de produtos têxteis quanto ao local de afixação da etiqueta de cuidados e conservação
Authors: Brito Anderson Santos de , Epsztejn Ruth , Fermam Ricardo Kropf Santos
Published: August 2019

Este trabalho visa propor sugestões de posicionamento da afixação da etiqueta têxtil em produtos têxteis verificando as boas práticas realizadas no mundo como parâmetro de indicação para a sugestão de inclusão futura no Regulamento Têxtil no Brasil.  Neste artigo verificou-se que o Brasil é um dos maiores fabricantes têxteis no mundo e produz um grande volume de materiais têxteis confeccionados nos quais possuem etiquetas de cuidado afixadas por força de legislação específica, sendo observado que o regulamento têxtil vigente carece de indicações a respeito do local da afixação da etiqueta têxtil nos produtos. Então, sem regulamentação especifica de posicionamento para afixação da etiqueta têxtil, o consumidor fica sem acesso as informações necessárias para a boa conservação e cuidado que pode induzir ao dano da peça, trazendo ao mesmo um prejuízo financeiro. E na área técnica, observam-se dúvidas por exemplo, relação à fixação da etiqueta em produtos confeccionados, dentre outros. Há, via de regra, a necessidade de “retrabalho” pelos setores de qualidade das empresas, onde as análises técnicas de troca por defeito dão-se por meio de um relacionamento conturbado com o consumidor, gerando a insatisfação do cliente. Desta forma, o desenvolvimento do trabalho foi baseado em pesquisas de regulamentos e normas das melhores ações dos maiores países exportadores mundiais de têxteis. Foram realizadas pesquisas com o consumidor e os profissionais da área têxtil, para verificar problemas causados pela falta de regulação deste tema. Os resultados obtidos norteiam indicação de boas práticas a ser utilizada pelo Brasil a fim de minimizar a falta de um guia oficial a respeito do tema.
In Silico Analysis of Gardnerella Genomospecies Detected in the Setting of Bacterial Vaginosis
Authors: Potter Robert F , Burnham Carey-Ann D , Dantas Gautam
Published: August 2019

BACKGROUND

Gardnerella vaginalis is implicated as one of the causative agents of bacterial vaginosis, but it can also be isolated from the vagina of healthy women. Previous efforts to study G. vaginalis identified 4 to 6 clades, but average nucleotide identity analysis indicates that G. vaginalis may be multiple species. Recently, Gardnerella was determined to be 13 genomospecies, with Gardnerella piottii, Gardnerella leopoldii, and Gardnerella swidsinkii delineated as separate species.

METHODS

We accessed 103 publicly available genomes annotated as G. vaginalis. We performed comprehensive taxonomic and phylogenomic analysis to quantify the number of species called G. vaginalis, the similarity of their core genes, and their burden of their accessory genes. We additionally analyzed publicly available metatranscriptomic data sets of bacterial vaginosis to determine whether the newly delineated genomospecies are present, and to identify putative conserved features of Gardnerella pathogenesis.

RESULTS

Gardnerella could be classified into 8 to 14 genomospecies depending on the in silico classification tools used. Consensus classification identified 9 different Gardnerella genomospecies, here annotated as GS01 through GS09. The genomospecies could be readily distinguished by the phylogeny of their shared genes and burden of accessory genes. All of the new genomospecies were identified in metatranscriptomes of bacterial vaginosis.

CONCLUSIONS

Multiple Gardnerella genomospecies operating in isolation or in concert with one another may be responsible for bacterial vaginosis. These results have important implications for future efforts to understand the evolution of the Gardnerella genomospecies, host–pathogen interactions of the genomospecies during bacterial vaginosis, diagnostic assay development for bacterial vaginosis, and metagenomic investigations of the vaginal microbiota.
Alcohol Consumption and Risk of Liver Cirrhosis: A Systematic Review and Meta-Analysis
Authors: Roerecke Michael , Vafaei Afshin , Hasan Omer S.M. , Chrystoja Bethany R. , Cruz Marcus , Lee Roy , Neuman Manuela G. , Rehm Jürgen
Published: August 2019

OBJECTIVES:

To systematically summarize the risk relationship between different levels of alcohol consumption and incidence of liver cirrhosis.

METHODS:

MEDLINE and Embase were searched up to March 6, 2019, to identify case–control and cohort studies with sex-specific results and more than 2 categories of drinking in relation to the incidence of liver cirrhosis. Study characteristics were extracted and random-effects meta-analyses and meta-regressions were conducted.

RESULTS:

A total of 7 cohort studies and 2 case–control studies met the inclusion criteria, providing data from 2,629,272 participants with 5,505 cases of liver cirrhosis. There was no increased risk for occasional drinkers. Consumption of one drink per day in comparison to long-term abstainers showed an increased risk for liver cirrhosis in women, but not in men. The risk for women was consistently higher compared to men. Drinking ≥5 drinks per day was associated with a substantially increased risk in both women (relative risk [RR] = 12.44, 95% confidence interval [CI]: 6.65–23.27 for 5–6 drinks, and RR = 24.58, 95% CI: 14.77–40.90 for ≥7 drinks) and men (RR = 3.80, 95% CI: 0.85–17.02, and RR = 6.93, 95% CI: 1.07–44.99, respectively). Heterogeneity across studies indicated an additional impact of other risk factors.

DISCUSSION:

Alcohol is a major risk factor for liver cirrhosis with risk increasing exponentially. Women may be at higher risk compared to men even with little alcohol consumption. More high-quality research is necessary to elucidate the role of other risk factors, such as genetic vulnerability, body weight, metabolic risk factors, and drinking patterns over the life course. High alcohol consumption should be avoided, and people drinking at high levels should receive interventions to reduce their intake.
Beyond Technological Literacy
Authors: Wylie Caitlin , Neeley Kathryn , Ferguson Sean
Published: August 2019

We consider scholarly conversations about digital citizenship as a continuation of centuries of discourse about citizenship, democracy, and technoscience. Conceptually, we critique portrayals of citizenship from Jeffersonian polities to technical literacy to critical health and environmental justice movements. This analysis forms the basis for proposing an alternative, normative theoretical perspective on citizens’ engagement in governance: the ethics of care. This framework enables a move from citizens’ civic engagement as motivated by duty and risk perception to motivated by an affective desire to care for oneself and others. Using the ethics of care, we explore a digital citizenship project about civic open data in Charlottesville, Virginia, as an example of stakeholders caring about and for the construction of digital technologies as well as relationships of mutual interdependence between government and citizens. Despite pervasive assumptions and institutional gaps that limit this project’s success, this case illustrates the potential power of reframing the motivations for democratic engagement as relational and affective rather than based on fear or duty alone.
Understanding Cosmo-Literature
Authors: Hosny Reham
Published: August 2019

The central objective of this paper is to provide a new conceptual theoretical framework starting from the role of new new media in shaping a new kind of literature, which I call Cosmo-Literature. Towards this, I start working from Levinson’s differentiation among old media, new media, and new new media to arrive at the difference among the variable types of media. Next, I address the role of new new media in establishing world democracies and changing the social, cultural, and political world map. After that, I investigate the terms of “global village” and “cosmopolitanism” in relation to literature. To clarify what I mean by Cosmo Literature, I will investigate two new new media novels: Only One Millimeter Away, an Arabic Facebook novel by the Moroccan novelist Abdel-Wahid Stitu, and Hearts, Keys and Puppetry an English Twitter novel by Neil Gaiman, to infer the characteristics of Cosmo-Literature in general and Cosmo narration in particular.
Indigenous internationalization: Indigenous worldviews, higher education, and Tribal Colleges and Universities
Authors: Sumida Huaman Elizabeth Alva , Chiu Belinda , Billy Carrie
Published: August 2019

This article examines the role of Indigenous knowledges in higher education through an exploration of internationalization at U.S. Tribal Colleges and Universities (TCUs). We affirm that examining internationalization efforts with historically marginalized and underserved populations provides an opportunity for interrogating inequitable power dynamics in knowledge construction, production, and transference vis-à-vis education and within a Western hegemonic model of modernity. Our discussion is anchored in decoloniality and Indigenous sustainable self-determination, which highlight educational initiatives that bolster Indigenous identities while addressing social, political, and environmental complications created by coloniality. Drawing from a five-year mixed-methods case study with TCUs, we offer Indigenous perspectives on place-based higher educational initiatives in relation to local and global concerns, specifically human and ecological sustainability. We propose a critical lens in Indigenous internationalization wherein Indigenous worldviews are vital responses to dominant notions of internationalization and historical limitations of education for Indigenous peoples.
Introduction to the special issue: The construction of knowledge in higher education studies: A Southern perspective
Authors: Guzmán-Valenzuela Carolina , Brunner José Joaquín
Published: August 2019

This special issue celebrates research in the higher education field with an interest in non-Western lines of inquiry. The six papers here emerge from Latin-America, Spain, the USA and India and draw on multiple perspectives and methodologies. They address tensions and challenges in higher education systems that experienced in concrete contexts and regions but that are yet, to some extent, experienced in higher education systems globally. More specifically, the variety of research questions, theories, methods and contexts displayed here raise critical questions about global forces attached to neoliberalism and competition for prestige, which in turn, frame current practices in higher education. This special issue, therefore, constitutes an epistemic space that gives visibility to narratives on higher education that have been in Santo’s words, invisible narratives on higher education but that are fast becoming more visible.

Published: August 2019

Land utilization changes of the natural resources conservation area of Pangandaran coastal area, that have been utilized as a marine tourism area, which affect many kinds of environmental degradation threats. Updating the condition of Pangandaran waters is essential due to its condition impacted by anthropogenic activities. Water condition monitoring was done by measuring nutrients as an indicator to assess the water fertility and pollution. Fourty five observation points were selected and divided into three locations, representing the condition of river, estuary/mangrove area, and open sea. Nutrients were analyzed by employing Standard Methods for The Examination of Water and Wastewater 22nd Edition 2012 (SMEWW). Currents and tides were measured for 15 days, used as the basis input of hydrodynamic model. The results showed that the highest of average value of nitrate was found in the estuary/mangrove forest which reached 0.998 mg.L-1. While, the highest phosphate content was observed in the river which reached 0.928 mg.L-1. The highest ammonia concentration was observed in the sea which reached 0.027 mg.L-1. N:P ratios in the study area are categorized <16, which showed that Pangandaran waters are in the condition of N-limitation. These conditions trigger blooming of phytoplankton due to the high concentration of nitrate. The higher nutrient concentration indicates that anthropogenic activities take place. Tidal current has an important role transporting nutrient in the estuary, triggering nutrient deposition and blooming tendency. Restrictions on residential areas and the utilization of coastal areas are an appropriate step to reduce the pollution level in Pangandaran waters.

The role of platelets in bleeding in patients with thrombocytopenia and hematological disease
Authors: Vinholt Pernille J.
Published: August 2019

This review evaluates the role of platelets in bleeding risk among patients with hematological disease and thrombocytopenia. Platelets are pivotal in primary hemostasis, and possess non-hemostatic properties involved in angiogenesis, tissue repair, inflammation and metastatis. Also, platelets safeguard vascular integrity in inflamed vessels. Overall, bleeding risk depends on the underlying disease, and patients with cancer and platelet count <6–10 × 109/L have a markedly increased bleeding risk, while the platelet count does not correlate with bleeding risk at higher platelet counts. Other factors might affect platelet properties and thus bleeding risk, for example, drugs, low hematocrit, coagulation system impairments or transfusion of dysfunctional donor platelets. For patients with leukemia and immune thrombocytopenia, reduced platelet activation, platelet aggregation, or thrombopoiesis, reflected by the reduced presence of reticulated platelets, are associated with bleeding phenotype. However, mechanistic insight into the cause of reduced platelet function in different thrombocytopenic conditions is sparse, except for some inherited platelet disorders. Promising tools for platelet function studies in thrombocytopenia are flow cytometry and biomarker studies on platelet constituents. An important message from this current paper is that bleeding risk assessment must be tailored to specific patient populations and cannot be applied broadly to all patients with thrombocytopenia.
An Easy In-Service Optical IP Network System for Residential Complex, Employing 1550 nm-Band CWDM and Layer-3 Switch
Authors: Nguyen HoangViet
Published: August 2019

We have proposed and demonstrated a novel architecture to implement in Coarse Wavelength-Division-Multiplexing (CWDM) technologies to give integrated broadband services for residential complex use system. For keeping the speed of 1000 Mbps at the bus IFs, CWDM technology is employed, and eight wavelengths are allocated to eight bus IFs, respectively. We also have evaluated characteristics of the transmission by calculated and measured the throughputs. The optical IP network can be easy in-service by adjusting the number of wavelengths and optical transceivers. We believe this novel scheme can be applied for future broadband network.
Characterization of the duration of treatment with diazoxide in infants with prolonged hyperinsulinism (PHI)
Authors: Raisingani Manish , Brar Preneet Cheema
Published: August 2019

Background

Prolonged neonatal hyperinsulinism (PHI) causes hypoglycemia in the neonatal period and is associated with perinatal stress. Even though diazoxide is an effective treatment option for PHI, it has serious adverse effects making an argument for safe yet expeditious wean off of diazoxide while ensuring normoglycemia. The objective of this study was to characterize clinical course, dose requirement and duration of treatment with diazoxide in our cohort of infants diagnosed with PHI.

Methods

A retrospective chart review of infants diagnosed with PHI during a 6-year period was done documenting the diagnostic workup and the duration of treatment with diazoxide.

Results

PHI was diagnosed (n = 20; mean ± standard deviation [SD]) at 14.3 ± 22.4 days. Elevated insulin (8.3 ± 8.4 mIU/L), normal cortisol (15.5 ± 6.6 μg/dL [6–21]), normal growth hormone (18.8 ± 15.7 ng/mL [0.1–6.2]) and inappropriate low serum free fatty acids (0.3 ± 0.2 mmol/L [>1.5]) levels were measured during hypoglycemia (plasma glucose <50 mg/dL). Detectable insulin at the time of hypoglycemia was measured in 17 of 20 infants while the same number (17/20) of infants had a positive glucagon stimulation test (GST). The dose of diazoxide was 10 ± 3.7 mg/kg/day and duration of treatment was 44.9 ± 27.9 days.

Conclusions

This study illustrates that the duration of treatment with diazoxide in infants with PHI can be shorter than previously reported in the literature. We speculate that active tapering of diazoxide started within a week after discharge from hospital as well an outpatient tapering of diazoxide based on glucose monitoring were possible reasons for this outcome.
Changes in body mass index in children on gonadotropin-releasing hormone agonist therapy with precocious puberty, early puberty or short stature
Authors: Censani Marisa , Feuer Alexis , Orton Sarah , Askin Gulce , Vogiatzi Maria
Published: August 2019

Background

The use of gonadotropin-releasing hormone agonists (GnRHa) for pubertal suppression has been associated with increased body mass index (BMI) in female subjects with central precocious puberty (CPP), although results have been so far conflicting. This study examined the effects of GnRHa therapy in both genders and in subjects treated for CPP, early puberty or short stature.

Methods

This was a longitudinal retrospective study of subjects followed at outpatient pediatric endocrinology clinics of an academic medical center from 2005 to 2014 receiving GnRHa therapy.

Results

At 12 months, subjects on depot GnRHa had a statistically significant increase in BMI standard deviation score (SDS) from baseline (0.13 ± 0.35, p < 0.02). Subjects with short stature (0.17 ± 0.34, p < 0.02) but not early or precocious puberty, and subjects with normal baseline BMI (0.18 ± 0.38, p < 0.02) had significant increases in BMI SDS; no significance was noted at 24 months. Male subjects did not have a significant increase in BMI SDS, whereas female subjects did (0.11 ± 0.36, p < 0.01).

Conclusions

Subjects with short stature, normal BMI at baseline and female sex had significant increases in BMI SDS at 12 months. This is the first study to show an increase in BMI SDS in children treated with GnRHa for short stature, and is one of the few studies to assess BMI changes in males.
Harmony and Discord: Development of Political Parties and Social Fragmentation in Hong Kong, 1980-2017
Authors: Yu Andrew Chun Kit
Published: August 2019

This paper seeks to examine why political parties in Hong Kong are fragmented and how the development of political parties in Hong Kong leads to social discord. Political parties started to emerge in Hong Kong in the 1980s. They had a golden opportunity to develop in the 1990s due to political reform, but why are political parties in Hong Kong still small, weak, with poor reputations and weak support? The author points out five factors that lead to the malfunction of political parties in Hong Kong. Although some factors are caused by the political parties themselves, the author argues that they are, all in all, constitutional or institutional factors, as they are long-term restraints directly set by the government since the colonial era. Due to the failure of party development in Hong Kong caused by constitutional and institutional restraints, the author will also discuss how this failure has lead to the political and social discord in the past two decades since the handover and the future.

Authors: Atia Ahmed Ibrahim , Gafar Sameh Mohammed
Published: August 2019

Electron paramagnetic resonance spectroscopy (EPR) has been used to assess the free radical signal in different kinds of milk powder. Buffalos, colostrum’s, butter, milk cows, goat, camel and commercial milk before and after γ-ray irradiation. Moreover, un-irradiated milk samples exhibited weak signals, but upon increasing the absorbed doses EPR signal intensities were increased. The useful dose range was from 0.1 to 11 kGy. The results show that the stability of the signal of milk powder in relation to gamma irradiation was in order as follows: buffalo’s buttermilk; camel; cows; commercial milk; goat; buffalo’s; and colostrum milk. This study was recommended to use EPR as a new technique in an evaluation, quality control of dairy products and food irradiation applications. These milk powders undergo the influence of γ-rays can be applied as radiation dosimeters. Moreover, it can be used in food preservation, food irradiation processing, medical sterilization and water treating.

Published: August 2019

The aim of this research was to assess the effect of soil contamination with titanium (Ti) and iron (Fe) at military sites in Ukraine using the avoidance and reproduction tests withFolsomia candida(springtail). The soil used for the tests was sampled in 2017 from Dolyna, Ivano-Frankivsk region, Ukraine from two plots, namely a contaminated and a control site. The sample site is a former military site previously used for tank training. At the control site mainly the concentrations of Ti and Fe were exceeded. The control soil was free from contamination. The avoidance test and reproduction test were conducted with the use of springtail speciesF. candida. The following nine levels of contamination with heavy metals were established: 1%, 1.5%, 5%, 10%, 15%, 25%, 50%, 75% and 100%. The duration of the avoidance test was 7 days, and that of the reproduction test was 28 days. Overall, the results show that the avoidance and reproduction tests with collembolans have the potential to be used as screening tools in an ecological risk assessment of heavy metals. In the avoidance test, the concentrations from 1.5 to 100% significantly decreased the number ofF. candidain the contamination site in comparison to the control site. At the same time, avoidance was not observed in the first concentration (1%). According to the reproduction test, the negative effect on the number ofF. candidajuveniles was observed beginning at the 10% dose. The half maximal effective concentration (EC50) for the avoidance test was 50.12%, while that for the reproduction test was 22.39%. The contamination with heavy metals at the military areas indicated the short- and long-term toxicity risk on the springtailF. candida.
Geeignete Messprozesse – Valide Informationen
Authors: Dietrich Edgar
Published: August 2019

Um im industriellen Bereich valide Informationen zur Beurteilung und Bewertung der Qualität von Fertigungseinrichtungen und der damit erzeugten Produkte zu erhalten, sind geeignete Messprozesse die zentrale Voraussetzung. Unter einem Messprozess versteht man dabei alle verwendeten Messsysteme und Sensoren unter realen Einsatzbedingungen. Um diese Forderung zu erfüllen, wurden über die Jahre unterschiedliche Verfahren entwickelt, anhand derer die Eignung von Messprozessen bewertet werden kann. Diese sind in Verbands- und Firmenrichtlinien sowie in ISO-Normen beschrieben. Der vorliegende Beitrag beschreibt die Entstehungsgeschichte dieser Dokumente und verweist auf den letzten Stand.

Die mit den Messsystemen bzw. den Sensoren ermittelten Messwerte müssen strukturiert verwaltet und mit beschreibenden Informationen ergänzt werden. Um dies sicher zu stellen, ist ein standardisiertes Datenformat erforderlich, in dem alle relevanten Informationen zu hinterlegen sind. Ein solches international anerkanntes Format gibt es bis heute nicht. Allerdings hat sich in der Autoindustrie das Datenformat AQDEF (Advanced Quality Data Format) durchgesetzt, auf das in dem Beitrag eingegangen wird. Weiter werden Hinwiese gegeben, wie anhand von Plausibilitätsprüfungen fehlerhafte Übermittlung der Informationen vermieden und inwieweit durch sinnvolle Visualisierung Zusammenhänge zwischen Prozessparameter und Qualitätsmerkmale hergestellt werden können.

Aufgrund der mittlerweile vorhandenen neuen Möglichkeiten werden typische Anwendungsfälle beschrieben und einen Ausblick auf die Veränderungen durch Technologien der Künstlichen Intelligenz hingewiesen.
„Tudjuk azt, hogy május 1-je nagyon jelentős kérdés…”

Published: August 2019

Az állampárti időszak képi kultúrájának fontos elemét képezik a május 1-i ünnepségek és felvonulások, melyek az ötvenes-hatvanas évek berendezkedésének, hatalomgyakorlásának fontos jellemzőjét mutatják meg. Jelen tanulmány a Rákosi- és Kádár-korszak két évtizedét elemzi a fényképek által hordozott jelentések folytonosságain és változásain keresztül, hiszen a kontinuitás és diszkontinuitás egyaránt jellemezte a vizsgált időszakot. A vizuális propaganda a kurrens ikonográfiai kutatások fontos vonulatát képezi, amely egybevág a kommunista, államszocialista rendszerek természetével is – a szovjet típusú rendszer, mint propaganda-állam, a tömegek folyamatos mobilizálásán, az ideológia primátusán alapult e nézet szerint. A május elsejei felvonulásról alkotott képzetek ismerősek a mai magyar lakosság számára, ennek ellenére hazánkban még nem nagyon vizsgálták ezek szemantikáját tudományos igénnyel, a kérdéskör reflektálatlan maradt. 
Az írás célja egy meghatározott kulturális gyakorlat (a május 1-i felvonulás) összekapcsolása a térrel, amely strukturálja ezeket a cselekvéseket (Sztálin tér, Felvonulási tér) és a hatalom szándékaival, valamint a megrendezés szempontjaival.

Tanulmányunkban a Nyolcak eszmei importőreként ismert Kernstok Károly ifjúaktjainak értelmezésére vállalkozunk a gyermekkor-történeti ikonográfia-ikonológia módszerével, az alkotásokat átható eszmetörténeti áramlatok tükrében, annak megválaszolása céljából, hogy a művek mögött munkáló eszmei motívumokon keresztül miképp jut kifejezésre a művész társadalom- és emberképe, illetve abból milyen következtetések vonhatók le a gyermek- és fiatalságszemléletre vonatkozóan. Az elemzések folyamán megkíséreljük felvázolni a Nyolcak és Kernstok művészetét meghatározó eszmei és esztétikai áramlatok, valamint a korabeli egyetemes művészeti irányzatok koncepcióinak a csoport és Kernstok festészetére gyakorolt hatását. A releváns eszmei áramlatok, hatások meghatározása során egyrészt Kernstoknak a polgári értelmiséggel való erőteljes szellemi kapcsolatainak vizsgálatából indulunk ki, másrészt pedig a művészettörténeti szakirodalom recepciótörténeti információi tájékoztatnak minket a főbb hatásokról. Végül az eszmetörténeti hatások feltérképezése után arra keressük a választ, hogy milyen releváns gyermekkor-történeti áramlatokkal állíthatók összefüggésbe a vizsgált művek. Az elemzések megalapozottá tétele érdekében indokolt munkánkat egy eszme- és társadalomtörténeti szempontok alapján újraszervezett, a Nyolcak és Kernstok Károly művészetére vonatkozó, a művészettörténeti szakirodalom információit és megközelítésmódjait felhasználó áttekintéssel kezdeni, hogy ezután kapcsolódási pontokat találjunk a nevelés- és gyermekkortörténet által tematizált korabeli eszmei áramlatokkal, a Nyolcak, az objektív idealista hagyomány, a polgári liberális értelmiség, az életreform, a reformpedagógia és a gyermektanulmány közötti kapcsolódási pontok feltérképezése érdekében. Ezt követően kezdjük meg az alkotások elemzését, immár a megalapozó fejezetekben körülírt megállapítások és összefüggések tükrében.

Timing metabolism in cartilage and bone: links between circadian clocks and tissue homeostasis
Authors: Gonçalves Cátia F , Meng Qing-Jun
Published: August 2019

The circadian system in mammals is responsible for the temporal coordination of multiple physiological and behavioural processes that are necessary for homeostasis. In the skeleton, it has long been known that metabolic functions of chondrocytes, osteoblasts and osteoclasts exhibit intrinsic circadian rhythms. In addition, results from animal models reveal a close connection between the disruption of circadian rhythms and skeletal disorders such as rheumatoid arthritis, osteoarthritis and osteoporosis. In this review, we summarise the latest insights into the genetic and biochemical mechanisms linking cartilage and bone physiology to the circadian clock system. We also discuss how this knowledge can be utilised to improve human health.
The Future of Two Festivals

BERLIN 1992 Flying into Berlin is now so very ordinary. No need to worry about wandering out of the narrow corridor over East Germany leading into the divided city; no fear now of being shot down by a watchful MIG; now the Frankfurt-Berlin train can stop where it likes and motorists can leave the autobahn on the way in. The fear and atmosphere of menace have gone. Checkpoint Charlie has gone; Bernard Samson has come out for the last time. No one will get riddled with bullets trying to cross the Wall because the Wall has disappeared. Was it ever there? Hard to believe as the West Berlin double-deckers pass the Brandenburg Gate and drive straight through to Alexanderplatz. A history of forty years has disappeared, to become a tick in time a hundred years hence. Surprisingly many former West Berliners are not too happy about this sudden...
Célia Bertin: Jean Renoir – A Life in Pictures
Authors: Pratley Gerald
Published: August 2019

RECENTLY, the scholarly Alistair Cooke was introducing John Mortimer's Renoir reminiscent tv-film series, Summer Lease on PBS. In describing the origins of the story, which lay in the author's family visits to Italy, Cooke started a train of thought on the number of artists over the years whose work was inspired by their parents' activities, family relations, the tales they heard as children, the travels they took and the institutions they attended, all forming an important part of their growing years and providing them with a vivid background to draw upon in their creative periods which followed. Co-incidentally, a new biography of the distinguished French filmmaker, Jean Renoir, the son the greatest painter of the time, provides us with a detailed and colourful description of how deeply influenced Jean was by his father, Auguste and family; and how much his films reflected this without in anyway detracting from Jean...
Hideko Takamine
Authors: Holloway Ron
Published: August 2019

AT SEVENTY, she's Japan's greatest living actress, often compared to Mary Pickford, but more like a Katherine Hepburn for the range of her talent and commanding presence of the screen -- Hideko Takamine. Despite being recognized as a screen immortal in Japan, only a handful of her more than three hundred film appearances are known in the United States, due to the tragic destruction of the Japanese film archives during the war. Thus she's known in the West mostly by her postwar films, made during that last great period of Japanese cinema of the 1950s and early 1960s, after which television was to replace moviegoing as the population's favourite form of entertainment. Rather late in her career, Takamine did venture into television, but was never satisfied with the results. Finally, in 1979, deciding that the new medium was not for her, she gracefully took leave of the screen to...
John Frankenheimer: shooting Against the Wall
Authors: Pratley Gerald
Published: August 2019

ON JUNE 26 last year all the clocks at the Tennessee State Prison in Nashville stopped at 9 o'clock. The iron doors clanged shut, the last of the prisoners filed out to be transferred to other prisons, and a deep silence settled over the long corridors and empty cell blocks once teeming with a thousand inmates. Today the clocks still say 9 o'clock, but the doors are open again and the place alive with the familiar sights and sounds of a film crew on location. And director John Frankenheimer is at last in a prison! When Frankenheimer made Birdman of Alcatraz thirty-two years ago he planned at first to shoot it there, but permission was refused and he had to settle for studio sets. This gave the film a "too clean look" he admits, but it was justified in part as the story was self-contained, like a poem, about...
Prague: A New Golem
Authors: Uhde Jan
Published: August 2019

THE ANCIENT LEGEND about Rabbi Löw and the human-sized clay figure Golem whom the Rabbi brought to life only to see his creation become a destructive force is closely tied to Prague, one of Europe's cultural marvels. The famous Paul Wegener's proto-expressionist 1915 film, Golem, was also shot in that city. This year, a new Golem is about to be born: An international film festival Golden Golem 95 will be held in Prague for the first time between 9-17 June. Its categories include International Competition for feature-length films, Panorama of World film, Czech film, Independent film, a Retrospective, a Film market, and others....
Venice 1994
Authors: Holloway Ron
Published: August 2019

VENICE 1994: ERMANNO OLIM'S GENESIS As befits a master filmmaker, Ermanno Olmi is reluctant to give interviews. He lets his films speak for themselves. A shy, self-effacing man, it's always been that way with Olmi. He was especially sparse on words when awarded the Golden Lion at the 1988 Venice festival for The Legend of a Holy Drinker and the Golden Palm at the 1978 Cannes festival for The Tree of Wooden Clogs. And there hasn't been a published interview with Olmi in nearly a decade. One reason for the reticence is the embarrassment of having to answer those all too frequent, nagging "how are you?" and "what have you been doing?" questions. For between the Cannes premieres of The Tree of Wooden Clogs (1978) and Cammina Cammina (1983) lay five years of inactivity, then another four years until Long Live the Lady (Lunga vita à la signora, 1987)...
Enfant Diabolique in International Cinema
Authors: Tan Kenneth
Published: August 2019

THE PRESENCE OF HORROR GENRE genre at the Singapore International Film Festival 1996 inspired these recollections: John Carpenter's remake of the seminal Village of the Damned featured in this year's Singapore Festival of Arts All-Night Horrorthon, is a chilling account of what happens when a small community of sinister children, endowed with telepathic and destructive powers, gradually unfolds evil plans for world domination. In this current age of contemporary film-making technology, the film's sound and special effects are superb, but that isn't what makes the film frightening. It is the notion of innocent, "helpless" children, rising above the domination that parents, teachers and adults at large have traditionally exerted over them, turning on the conventional authority figures, threatening them, violating them, and ultimately triumphing over them. This is the theme of the enfant diabolique, or diabolical child, which has found expression and gained favour in numerous films made all over...
John Logie Baird and Television (Part 1)
Authors: Hills Adrian R.
Published: August 2019

EYE OF THE WORLD: JOHN LOGIE BAIRD AND TELEVISION (Part1) 1996 is the seventieth anniversary of the birth of television. John Logie Baird, the father of this pervasive technology, first publicly demonstrated television on 26 January 1926, in his small laboratory in the Soho district of London. Although large companies with great financial support were also working on the problem of television, Baird managed to surpass them all with very little money, a handful of unpaid helpers and equipment pieced together using rather unconventional materials. For example, Baird's choice of mechanical scanning as the most effective way of achieving true television required the use of spinning discs -- which of financial necessity were made of hatboxes and mounted on a coffin lid. This short account, written for the anniversary of the invention of television, not only recounts the events that led up to the first demonstration of television by...
Andersonville Revisited
Authors: Pratley Gerald
Published: August 2019

JOHN FRANKENHEIMER'S LATERST FILM, ANDERSONVILLE, opened recently in the USA on the Turner Television Network to excellent reviews and a highly favourable audience response. His 31st motion picture, it takes place during the American Civil War and depicts for the first time on film the terrible suffering of Northern soldiers imprisoned in an overcrowded poorly managed camp run by the army of the South. An atrocity from the past, it also speaks graphically of the barbarities of the present war in Bosnia-Herzegovina and gives terrible meaning once again to the memories of the Holocaust. Implicit in Frankenheimer's treatment and graphic images of man's ever-present brutality towards mankind is the awareness of the powerful forces controlling the lives of certain individuals motivated by power and greed -- a theme underlining much of his work and informing the actions of so many of his characters. Andersonville In 1864, more than 32,000...

PSICANÁLISE: uma leitura heideggeriana
Authors: Loparic Zeljko
Published: August 2019

SÍNTESE - O texto não fala de um confronto entre Heidegger e Freud. A crítica da psicanálise propõe uma nova leitura na forma de uma desconstrução conceitual. O autor faz uma análise da origem metafisica dos conceitos de psicanálise e de seu instrumental mitológico, sugerindo um universo conceituai que nasce da superação da metafisica. Trata-se de "substituir modo de teorizar da psicanálise por um modo de pensar e de conhecer radicalmente diferente."
The honey of Plebeia molesta and other melliferous insects in the peasant culture of the Northwest of Córdoba, Argentina
Authors: Geisa Melisa Gabriela , Hilgert Norma Inés
Published: August 2019

Bees called meliponas (family Apidae, tribe Meliponini) are native stingless bees (ANSA) whose products (honey and other elements from the hive) have been employed by various indigenous and peasant cultures since ancient times. This study lists the native honeybee species known to criollos from northwest Córdoba. It also analyzes in particular the relationship between peasants living in three different environments in the region and the uses they assign to Plebeia molesta honey. Semi­structured interviews were conducted with 42 key interlocutors. To analyze the obtained information qualitative and quantitative methods were used. Local people recognize 4 native melliferous insects, being the one called “quella” the most important. Its honey is used mainly for medicinal purposes and as food. The predominant use as medicine is ingestion in pure form (45%) and the most frequently treated conditions are those related to the respiratory system (88.53%). In relation to the changes perceived in the availability of this resource, 75% of the interlocutors considered that the frequency of nest encounters has decreased in the last decades. The assigned uses of honey show a high variability in relation to the socio­cultural and occupational characteristics of the inhabitants. It is concluded that this honey is a valuable resource for farmers in the region. Given the perceived decrease of these populations, management and conservation strategies should be implemented that,incorporating the peasant point of view, guarantee their accessibility and perpetuity.
