Робота виконана в рамках НДР 0112U000542 «Біохімічні механізми токсичності наночастинок різної природи та інших антропогенних і біогенних токсикантів і біологічних систем» та 0116U003353 «Біохімічні механізми порушень метаболізму за умов надходження до організму токсикантів різного ґенезу».  Контактний дерматит (КД) – одне з найпоширеніших захворювань на сьогодні, що розвивається у відповідь на контакт із різноманітними чинниками, одним з яких є нікель та його солі. Розвиток оксидативного та нітрооксидативного стресу є універсальним механізмом розвитку, в тому числі й захворювань шкіри та КД.Мета дослідження – вивчити ефективність наноінкапсульованої та вільної форми препарату пегільованої супероксиддисмутази (СОД) на моделі контактного нікелевого алергійного дерматиту.Матеріали і методи. Дослідження проводили на 40 щурах-самцях, яких рандомізовано на чотири групи (n=10): перша – інтактні тварини; друга – тварини з експериментальним КД; третя – щури з КД, яким для корекції застосовували ПЕГ-СОД у вільній формі (КД + СОД); четверта – особини з КД, яким наносили наноінкапсульовану форму СОД (КД + нано-СОД). Полімерні хітозанові наночастинки готували за методикою Z. Hussain et al. (2013). Інтенсивність розвитку КД оцінювали за візуальною шкалою та товщиною шкірної складки. Також досліджували показники оксидативного та нітрооксидативного стресу.Результати досліджень та їх обговорення. Аплікація 5 % сульфату нікелю викликає розвиток контактного дерматиту та оксидативного і нітрооксидативного стресу зі зростанням рівня продуктів ПОЛ та ослабленням ланок ендогенного антиоксидантного захисту. Застосування вільної форми пегільованої супероксиддисмутази супроводжується зниженням інтенсивності ураження як за візуальними ознаками, так і достовірним зниженням інтенсивності ПОЛ та активацією показників антиоксидантного захисту. Наноінкапсульвана форма пегільованої супероксиддисмутази вірогідно більш інтенсивно покращує стан уражених шкірних покривів досліджуваних тварин, у тому числі й порівняно з групою щурів, котрі отримували її вільну форму: достовірно кращими були показники як і ПОЛ, так і антиоксидантного захисту в сироватці крові та тканинах печінки.Висновки. Отримані результати дослідження свідчать по перспективність подальшого вивчення та впровадження у клінічну практику наноінкапсульованих форм СОД для лікування контактних дерматитів.

Adil bir gelir dağılımının sağlanması cari ücret seviyesinin oluşmasını gerekli kılmaktadır fakat işgücünün sahip olduğu özelikler, işin niteliği ve ücret yapısından kaynaklanan faktörlere ilaveten işgücü piyasasındaki gözlenen tabakalı yapı aynı işe farklı ücret ödenmesine yol açmaktadır. İnşaat sektörü Türkiye’nin hızlı gelişen ve katma değer yaratan sektörlerinden biri olmakla birlikte istihdam yaratma kapasitesi bakımından önem taşımaktadır. Fakat sektörde farklı vasıf ve niteliğe sahip birçok farklı meslek grubu, zayıf eğitim istihdam ilişkisi ve ağır çalışma koşulları gözlenmektedir. Araştırma sonuçlarına göre ücret farklılığına neden olan faktörler eğitim ve mesleki tecrübe (yaş) gibi işgücünün özelliklerinden olarak ortaya çıkmıştır. Büyük kurumsal firmada çalışanların taşeron firmada çalışanlara göre eğitim düzeyi, yaş ve mesleki tecrübesinin daha yüksek olduğu, daha yüksek ve düzenli ücret aldığı, kariyer olanaklarının ve sosyal yardımların daha fazla olduğu buna karşın her iki gruptaki firmalarda sendikalaşmanın olmadığı tespit edilmiştir. Bu kapsamda ortaya çıkan ücret farklılıkları sektördeki tabakalı yapıyı ortaya koymaktadır.
Avrupa Birliği Bölgesel Politikalarında Mali Araçların Rolü: Türkiye Açısından Bir Değerlendirme

İkinci Dünya Savaşı
sonrası Roma Antlaşmasıyla temelleri atılan Avrupa Topluluğu, kurulduğundan

sorunun ortadan kaldırılması için ortak önlemler ve politikalar geliştirilmeye
çalışılmıştır. Bu önlemler içerisinde en dikkat çekici olan üye devletlere
sağlanan yapısal fonlar ve aday ülkelere yönelik geliştirilen katılım öncesi

Topluluk içerisindeki bölgesel dengesizlikleri artarken söz konusu mali
araçlarda reformların yapılması ihtiyacı ortaya çıkmıştır. Avrupa Birliği’ni

Published: July 2018

The slipper lobster Scyllarides delfosi is an important resource captured by fishery fleets of red lobster (Panulirus argus westonii) in northern Brazil. Despite the economic potential of this species, information on its biological and fishery aspects is still nonexistent. This study was conducted using four-year data on slipper lobster (2001 and 2003, 2013 and 2014) to analyse population structure and estimate fecundity and egg size of S. delfosi. A total of 547 slipper lobsters, S. delfosi, were collected. Ovigerous females and individuals of all size classes were captured by the fleet, mostly individuals newly recruited to the adult stock. These lobsters showed a 7-mm decrease in total mean length over a period of 10 years. Fecundity ranged from 24,710 to 190,060 eggs and egg diameter ranged from 0.60 to 0.64 mm. Research on life cycle, reproduction, and growth of S. delfosi is essential to provide support for the sustainable exploitation of this species, which is considered by-catch on the northern Brazilian coast, and as such, has no adequate public policies regarding its management.

Colloquium 1 Parmenides, Liars, and Mortal Incompleteness
Authors: Cherubin Rose
Published: July 2018

On the road of inquiry that Parmenides’ goddess recommends, one is to say and conceive that what-is is one, unmoving, continuous, ungenerated, undestroyed, complete, and undivided. Yet the goddess’s arguments in favor of this road use negations, distinctions, divisions, and references to generation and destruction. The requisites of inquiry that she outlines are both defined on and at odds with other features that inquiry appears to require. This essay argues that the goddess’s arguments manifest something like a liar paradox: She demonstrates on the basis of the opinions of mortals that mortals’ opinions are flawed. If so, then the goddess’s arguments do not establish that what-is is one and unchanging. What they show is that what inquiry and inference seem to require, given the opinions of mortals, is at odds with itself. To refer to what-is is to make aletheia impossible to reach. To be mortal, for Parmenides, is to journey through that incompleteness.

The field of atmospheric science has been enhanced by its long-standing collaboration with entities with specific needs. This chapter and the two subsequent ones describe how applications have worked to advance the science at the same time that the science has served the needs of society. This chapter briefly reviews the synergy between the applications and advancing the science. It specifically describes progress in weather modification, aviation weather, and applications for security. Each of these applications has resulted in enhanced understanding of the physics and dynamics of the atmosphere, new and improved observing equipment, better models, and a push for greater computing power.
Influence of Lake Erie on a Lake Ontario Lake-Effect Snowstorm
Authors: Kristovich David A. R. , Bard Luke , Stoecker Leslie , Geerts Bart
Published: July 2018

Annual lake-effect snowstorms, which develop through surface buoyant instability and upward moisture transport from the Laurentian Great Lakes, lead to important local increases in snowfall to the south and east. Surface wind patterns during cold-air outbreaks often result in areas where the air is modified by more than one Great Lake. While it is known that boundary layer air that has crossed multiple lakes can produce particularly intense snow, few observations are available on the process by which this occurs. This study examines unique observations taken during the Ontario Winter Lake-effect Systems (OWLeS) field project to document the process by which Lake Erie influenced snowfall that was produced over Lake Ontario on 28 January 2014. During the event, lake-effect clouds and snow that developed over Lake Erie extended northeastward toward Lake Ontario. OWLeS and operational observations showed that the clouds from Lake Erie disappeared (and snow greatly decreased) as they approached the Lake Ontario shoreline. This clear-air zone was due to mesoscale subsidence, apparently due to the divergence of winds moving from land to the smoother lake surface. However, the influence of Lake Erie in producing a deeper lake-effect boundary layer, thicker clouds, increased turbulence magnitudes, and heavier snow was identified farther downwind over Lake Ontario. It is hypothesized that the combination of a low-stability, high-moisture boundary layer as well as convective eddies and limited snow particles crossing the mesoscale subsidence region locally enhanced the lake-effect system over Lake Ontario within the plume of air originating over Lake Erie.
Experiences, causes and measures to tackle institutional incongruence and informal economic activity in South-East Europe
Authors: Littlewood David , Rogers Peter , Williams Colin
Published: July 2018

To explain the prevalence and persistence of informal economic activity globally, scholars have recently advanced an institutional incongruence perspective. Institutional incongruence exists where there is a misalignment between what is considered legitimate by a society’s formal institutions (e.g. its laws and regulations) and its informal institutions (e.g. norms, values and beliefs). Reporting findings from a series of qualitative focus groups in Bulgaria, Croatia and the Former Yugoslav Republic of Macedonia, this article explores relationships between such institutional incongruence and informal economic activity. In particular, it sheds light on how informality and institutional incongruence are experienced by individuals in South-East Europe. It furthermore provides insights on the causes of such incongruence, and how it can lead to informal economic activity. Finally, it reports on individuals’ perceptions towards different measures to tackle institutional incongruence and informal economic activity, with implications for policymakers in South-East Europe and more widely.
Is There More to Resourcefulness Than Personal and Social Skills?
Authors: Zauszniewski Jaclene A. , Herbell Kayla , Burant Christopher
Published: July 2018

This study examined relationships among personal and social resourcefulness and spiritual practices and their associations with perceived stress, depressive symptoms, and self-assessed health in 138 women caregivers of elders with dementia. Caregivers who rated high on personal and social resourcefulness and spiritual practices (by median splits) had the lowest perceived stress, fewest depressive symptoms, and best self-assessed health, followed in sequence by women rating high on two of the three, high on one of the three, and low on all three. Hierarchical regression analyses that introduced spiritual practices after resourcefulness showed significant increases in the R-square change by 3% and 5% for perceived stress and depressive symptoms, respectively, but no significant change for self-assessed health. Strong associations among personal and social resourcefulness and spiritual practices, and similar relationships with two health outcomes, suggest that spiritual practices may be a third dimension of resourcefulness.

Published: July 2018

Surgical management of otitis media with effusion and recurrent acute otitis media includes myringotomy and the use of ventilation tubes. Since this procedure was reintroduced by Armstrong in 1954, it has become one of the most commonly performed operations in otolaryngology. In most series perforation of the tympanic membrane in some patients has been reported after spontaneous extrusion or removal of the tympanostomy tubes. We present a retrospective review designed to examine the incidence of persisting perforations of the tympanic membrane in our series of 2604 operated ears. The study also identifies and analyzes the variables and the contributing risk factors. Perforations occurred in 3.06% of the ears: with a greater incidence in children younger than 5 years, when the indication was recurrent purulent otitis media, with the use of long‐term Goode T tubes, in cases with repeated insertions of ventilation tubes, and in cases in which postoperative otorrhea was frequent.
Unraveling the effect of alliance experience on alliance formation and alliance governance structure: A meta-analytic approach
Authors: Wang Peng , Ma Yongyuan , Hu Zhongquan
Published: July 2018

Alliance experience plays a crucial role in the stage of alliance formation. However, theoretical gaps and empirical controversies exist in the analyses of its effects on alliance formation and alliance governance structure. Drawing on the method of meta-analysis, we have systematically searched and coded previous empirical studies, generating a database of 91 empirical studies in all. Through classifying alliance experience into general and partner-specific alliance experience, we seek to examine the different effects of these two types of alliance experience on alliance formation and alliance governance structure. We enrich the classification of alliance experience in terms of governance structure to address the disadvantages of this classification in explaining the resulting effects. Our research uses meta-regression to provide evidence about how contextual contingencies affect the alliance experience–alliance governance structure link.

Published: July 2018

We aim to test whether the association between glucose control and cognitive function still holds true in elderly patients with diabetes mellitus (DM) and Alzheimer disease (AD) under health-care case management. We enrolled 100 patients with DM (mean age: 74.6 years; male: 49%) and 102 patients with AD (mean age: 77.9 years; male: 41.2%) consecutively from the Diabetes Shared Care Program and the memory clinic. These patients were followed up every 3 months with scheduled examinations. Most patients with AD were at early stage and DM was a common comorbidity (n = 42). In the DM group, there were 76 patients with subjective cognitive decline and 19 patients with mild cognitive impairment, but none sought further consultation. After adjusting for age, sex, education, and comorbidity, higher levels of glycated hemoglobin (HbA1C) were not associated with lower Mini-Mental State Examination (MMSE) scores in the DM group (coefficient: 0.03; 95% confidence interval [CI]: −0.44 to 0.50) and lower MMSE scores were not associated with higher HbA1C in the AD group either (coefficient: −0.05; 95% CI: −0.11 to 0.01). When additionally accounting for the variability of HbA1C in the DM group, higher standard deviation of HbA1C was associated with poor clock drawing test scores, but not MMSE. The coexistence of AD-DM was common, but the association between hyperglycemia and cognitive impairment was not seen in patients under regular health monitoring.
On a consistent finite-strain shell theory for incompressible hyperelastic materials
Authors: Li Yuanyou , Dai Hui-Hui , Wang Jiong
Published: July 2018

In this paper, a consistent finite-strain shell theory for incompressible hyperelastic materials is formulated. First, for a shell structure made of an incompressible material, the three-dimensional (3D) governing system is derived through the variational approach, which is composed of the mechanical field equation and the constraint equation. Then, series expansions of the independent variables are conducted about the bottom surface and along the thickness direction of the shell. The recursive relations of the coefficient functions in the series expansions can be derived from the original 3D governing system. Further from the top surface boundary condition, a 2D vector shell equation is obtained, which represents the local force-balance of a shell element. The associated edge boundary conditions are also proposed. It is verified that shell equation system is consistent with the 3D variational formulation. The weak formulation of the shell equation is established for future numerical calculations. To show the validity of the shell theory, the axisymmetric deformations of a spherical and a circular cylindrical shell made of incompressible neo-Hookean materials are studied. By comparing with the exact solutions, it is shown that the asymptotic solutions obtained from the shell theory attain the accuracy of O( h2).

Background:

With many options now available, first therapy choice is challenging in multiple sclerosis (MS) and depends mainly on neurologist and patient preferences.

Objectives:

To identify prognostic factors for early switch after first therapy choice.

Methods:

Newly diagnosed relapsing–remitting MS patients from 24 Italian centers were included. We evaluated the association of baseline demographics, clinical, and magnetic resonance imaging (MRI) data to the switch probability for lack of efficacy or intolerance/safety with a multivariate Cox analysis and estimated switch rates by competing risks models.

Results:

We enrolled 3025 patients. The overall switch frequency was 48% after 3 years. Switch risk for lack of efficacy was lower with fingolimod (hazard ratio (HR) = 0.50; p = 0.009), natalizumab (HR = 0.13; p < 0.001), dimethyl-fumarate (HR = 0.60; p = 0.037), teriflunomide (HR = 0.21; p = 0.031) as compared to interferons. Younger age (HR = 0.96; p < 0.001), diagnosis delay (HR = 1.23; p = 0.021), higher baseline Expanded Disability Status Scale (HR = 1.17; p = 0.001), and spinal cord lesions (HR = 1.46; p = 0.001) were independently associated with higher inefficacy switch rates. We found lower switch for intolerance/safety with glatiramer acetate (HR = 0.61; p = 0.001), fingolimod (HR = 0.35; p = 0.002), and dimethyl-fumarate (HR = 0.57; p = 0.022) as compared to interferons, while it increased with natalizumab (HR = 1.43; p = 0.022). Comorbidities were associated with intolerance switch (HR = 1.28; p = 0.047).

Conclusion:

Several factors are associated with higher switch risk in patients starting a first-line therapy and could be integrated in the decision-making process of first treatment choice.
Systematic review of the impact of arts for health activities on health, wellbeing and quality of life of older people living in care homes
Authors: Curtis Amy , Gibson Lucy , O’Brien Mary , Roe Brenda
Published: July 2018

Care home populations frequently feature older people who often experience poor physical health and cognitive difficulties, along with vulnerability to psychological and social stressors. To date there has been no systematic review which focuses on the impact of arts for health activities to the care home population. Evidence was sourced from several databases and 71 studies were deemed eligible for inclusion in this review. These studies underwent data extraction and quality appraisal and the findings associated with health, wellbeing and quality of life are presented within this paper.
Informant Personality Is Associated With Ratings of Memory Problems in Older Adults
Authors: Buchanan Tom , Loveday Catherine
Published: July 2018

Memory complaints are a key diagnostic criterion for dementia and mild cognitive impairment. Rating scales can be used to capture information about individuals’ memory problems from informants such as family members. However, problems with scale reliability suggest that individual differences influence the ratings informants provide. This project tested whether informants’ neuroticism was associated with their ratings of an older adult’s memory. In an online study, 293 volunteers completed a Five-Factor Personality Questionnaire and used 2 memory questionnaires to provide ratings of memory problems in an older individual they knew well. Rater neuroticism correlated positively with estimates of memory problems: More neurotic informants provided higher estimates of memory difficulties in the person they were rating. A second study replicated this finding with 786 volunteers and another widely used memory measure, the AD8. In both studies, exploratory analyses suggested the effect size was large enough to impact on clinical practice.
Tradeoff between compression ratio and decoding delay of distributed source coding for uplink transmissions in machine-type communication
Authors: Wang Wen , Zhu Jinkang , Zhang Sihai , Zhou Wuyang
Published: July 2018

Rapid growth of machine-type communications devices challenges the future network with a significant aggregated data traffic. Distributed source coding is a promising technique that compresses data sources and decreases required aggregated data transmission rate. In this article, we discuss the merits and demerits of deploying distributed source coding in machine-type communications uplink transmissions. We analyze how the decoding delay and storage consumption scale with the number of users and prove that the average decoding delay grows linearly with the user number under some assumptions. A machine-type communications uplink transmission scheme adopting clustered distributed source coding is proposed to balance the compression ratio and decoding delay of distributed source coding where users are divided into independently encoded and decoded clusters. We evaluate three clustering algorithms, grid dividing, Weighted Pair Group Method with Arithmetic Mean, and K-medoids in our system model. The grid dividing algorithm clusters users based on their locations, while Weighted Pair Group Method with Arithmetic Mean and K-medoids cluster users using the correlation intensity between them. Our simulation results show that Weighted Pair Group Method with Arithmetic Mean and K-medoids outperform grid dividing on compression ratio and K-medoids and grid dividing have a more balanced delay distribution among different clusters than Weighted Pair Group Method with Arithmetic Mean.
Electromyogram-based hand gesture recognition robust to various arm postures
Authors: Rhee Kiwon , Shin Hyun-Chool
Published: July 2018

In the recognition of electromyogram-based hand gestures, the recognition accuracy may be degraded during the actual stage of practical applications for various reasons such as electrode positioning bias and different subjects. Besides these, the change in electromyogram signals due to different arm postures even for identical hand gestures is also an important issue. We propose an electromyogram-based hand gesture recognition technique robust to diverse arm postures. The proposed method uses both the signals of the accelerometer and electromyogram simultaneously to recognize correct hand gestures even for various arm postures. For the recognition of hand gestures, the electromyogram signals are statistically modeled considering the arm postures. In the experiments, we compared the cases that took into account the arm postures with the cases that disregarded the arm postures for the recognition of hand gestures. In the cases in which varied arm postures were disregarded, the recognition accuracy for correct hand gestures was 54.1%, whereas the cases using the method proposed in this study showed an 85.7% average recognition accuracy for hand gestures, an improvement of more than 31.6%. In this study, accelerometer and electromyogram signals were used simultaneously, which compensated the effect of different arm postures on the electromyogram signals and therefore improved the recognition accuracy of hand gestures.
Dupuytren Disease Management Trends: A Survey of Hand Surgeons
Authors: Carr Logan , Michelotti Brett , Brgoch Morgan , Hauck Randy , Ingraham John
Published: July 2018

Background: Indication for intervention in Dupuytren disease is influenced by many factors, including location and extent of disease, surgeon preference, and comfort level with different treatment techniques. The aim of this study was to determine current Dupuytren disease management trends. Methods: A questionnaire was sent through the American Society for Surgery of the Hand to all members. In addition to demographic data, questions focused on indications for different procedural interventions based on location of disease, age, and activity level of the patient. Results: Approximately 24% of respondents completed the survey. Respondents were mostly orthopedic surgeons in private practice who do not work with residents or fellows. Respondents preferred collagenase over needle aponeurotomy and limited fasciectomy for primary Dupuytren disease involving only the metacarpophalangeal (MCP) joint. Limited fasciectomy was the preferred treatment for primary Dupuytren disease involving the MCP and proximal interphalangeal joints. For a patient amenable to any treatment option, the majority would use collagenase, although 87.1% felt that fasciectomy offered the longest disease-free interval. Furthermore, given the option of a young, working patient, 42.7% would use collagenase, while plastic and general surgeons were more likely to treat this patient with limited fasciectomy. More plastic surgeons (vs orthopedic) believe that limited fasciectomy yields the longest disease-free interval. For a patient amenable to any surgical option, orthopedic surgeons prefer collagenase, whereas plastic hand surgeons prefer a limited fasciectomy. Conclusion: There are several procedural options for the treatment of Dupuytren disease. This study details current practice patterns among hand surgeons and reveals the increasingly prevalent use of collagenase.
Study on automatic deduction method of overall transfer equation for tree systems as well as closed-loop-and-branch-mixed systems
Authors: Sun Lu , Wang Guoping , Rui Xiaoting , Rui Xue
Published: July 2018

The transfer matrix method for multibody systems has been developed for 20 years and improved constantly. The new version of transfer matrix method for multibody system and the automatic deduction method of overall transfer equation presented in recent years make it more convenient of the method for engineering application. In this article, by first defining branch subsystem, any complex multibody system may be regarded as the assembling of branch subsystems and simple chain subsystems. If there are closed loops in the system, the loops should be “cut off,” thus a pair of “new boundaries” are generated at each “cutting-off” point. The relationship between the state vectors of the pair of “new boundaries” may be described by a supplement equation. Based on above work, the automatic deduction method of overall transfer equation for tree systems as well as closed-loop-and-branch-mixed systems is formed. The results of numerical examples obtained by the automatic deduction method and ADAMS software for tree system dynamics as well as mixed system dynamics have good agreements, which validate the features of proposed method such as high computational speed, more effective for complex systems, no need of the system global dynamics equation, highly programmable, as well as convenient popularization and application in engineering.
Step children of the science department? The neglect of the Grade 8 and 9 natural sciences teachers in South African secondary schools
Authors: Malinga Cynthia B , Jita Loyiso C
Published: July 2018

To date, little research has been conducted on subject leadership by primary and/or junior secondary school heads of department (HODs). Unlike their senior secondary school counterparts, South African science HODs have the more complex task of leading in the multidisciplinary context of natural sciences (NS 1 ). Such leadership comes in addition to the complications of role ambiguity, limited time and authority that are inherent in the HOD position. Using interviews and 360° multi-rater by four teachers and subject meeting observations, data were transcribed and categorised into themes that describe the instructional leadership practices of three NS HODs in South Africa. This paper is part of a more comprehensive PhD study. It suggests that providing leadership for NS teaching is more complex in practice than has been reported to date. In the context of increasing focus on accountability and national testing, the unintended consequence has been the neglect of the junior secondary NS teachers by the HODs. Furthermore, the data suggest that the HODs tend to limit their attention to areas of their own specialisation. The paper concludes with a conceptual framework that provides guidance for improving instructional leadership by the HODs in such multidisciplinary contexts, especially for the junior secondary school levels. It also recommends the restructuring of the conglomerate departments to make them more effective.
Facilitating youth development through service-learning: Social justice implications for underserved youth
Authors: Curtis Christopher A
Published: July 2018

The implications of how service-learning participation can enhance civic knowledge and engagement among young people are discussed at length in the existing literature. However, research that explores the utility of formalizing service-learning as a means of enriching civic education for underserved and minority youth is lacking, particularly within the context of secondary education. The purpose of this article is to contribute to the discourse around increasing the use of service-learning programs as a means of supplementing existing methods that facilitate well-rounded youth development (e.g. school curricula, afterschool programs, mentorship) and enhance well-being among underserved youth within a social justice framework. The aims of this article are met by first illuminating the risk factors facing minority and underserved youth. The social justice implications of service-learning participation for youth are then discussed. Finally, the feasibility of utilizing service-learning as a protective factor for marginalized youth is explored.
Possibilities of a Professor
Authors: Kuriakose Francis
Published: July 2018

University as an institution has shown structural and functional uniformity across historical periods and cultures, despite distinct evolution in response to local needs. Historically, social norms, political stability and economic concerns were the variables that determined the objectives of higher education. Today, normative concerns about higher education are exclusively guided by economic rationale. The transformative potential of higher education in cultivating responsive and responsible individuals is ignored. In this context, this article examines the possibilities that a professor has as a transformative agent in a university. The author models a professor in four principal roles—as a scholar and public intellectual and as a reducer of rent seeking and information asymmetry. The normative concerns that build this model have been drawn from historical roles of teachers in universities and experimental models in early education. While the professor as a scholar and as a public intellectual are traditional roles that need to be revisited in the modern context, reducing rent seeking and information asymmetry are phenomena of a market society that should be countered. By performing these roles, a professor not only creates and disseminates knowledge, but also encourages students to make decisions that are socially productive as well as individually gratifying.
Kafka’s Animations
Authors: Henkel Brook
Published: July 2018

Around 1910 trick films by Edwin S. Porter, Émile Cohl, and others fascinated writers and critics by bringing objects to life and upending the dominant roles of human actors found in drama and literature. The animated objects and thing-like humans in Franz Kafka’s writings represent a unique response to this little-known history of early cinema. Focusing on “Blumfeld, an Elderly Bachelor,” “The Bucket Rider,” and “The Cares of a Family Man,” this article shows how Kafka’s stories draw, reflect, and expand on the possibilities of contemporaneous trick films by introducing animated objects into their narrative worlds. Inspired by cinema, these literary animations trace out complex social relations among humans and things and challenge the powers of reification that Theodor W. Adorno and others more typically identify with Odradek and related figures in Kafka’s writings.
Eggs and Steam Hammers

The poet and singer-songwriter Wolf Biermann was a member of the East German chapter of PEN International, a UNESCO-affiliated global literary association. Unlike other East German literary organizations, DDR PEN members and leaders tried at least occasionally to protect Biermann even after he was expelled from East Germany in 1976. This article assesses DDR PEN’s reactions to Biermann given its multiple functions as a representative of East German and Soviet bloc cultural diplomacy, an East German literary association hoping to protect some autonomous activity and free discussion, and an actor in a complex trans systemic (cross-Curtain) international environment.
Zafer Şenocak’s “Turkish Turn”
Authors: Dickinson Kristin
Published: July 2018

Whereas language constitutes one key vessel of historical remembering, the act of translation in Zafer Şenocak’s 2008 novel Köşk (The Pavilion) reveals how modern Turkish has also enabled historical forgetting, in its assertion of a monolingual Turkish populace over and against the multiethnic and multilingual makeup of the Ottoman Empire. Through an emphasis on the tropes of absence and translational reversal, Köşk then brings the history of linguistic modernization in Turkey to bear on contemporary integration policy and an implicit ethnicization of the German language in the Federal Republic of Germany. In doing so, it asks implicit questions about who has the right to speak a language as a nonethnic subject, and to remember a “national” past as both a noncitizen and a nonresident.
Gene editing in human development: ethical concerns and practical applications
Authors: Rossant Janet
Published: July 2018

The amazing power of CRISPR-Cas9 gene editing tools and other related technologies has impacted all areas of biology today. It has also raised ethical concerns, particularly with regard to the possibility of generating heritable changes in the human genome – so-called germline gene editing. Although technical and safety issues suggest that this approach is far from clinical application, gene editing as a research tool is moving forward in human embryos, non-human primates and in stem cell-derived embryoids. These studies are already providing new information relevant to our understanding of normal human development, infertility, early pregnancy loss and pluripotent stem cell origins.

Enthesitis is a key feature of several different rheumatic diseases. Its pathophysiology is only partially known due to the lack of access to human tissue and the shortage of reliable animal models for enthesitis. Here, we aimed to develop a model that mimics the effector phase of enthesitis and reliably leads to inflammation and new bone formation. Enthesitis was induced by local injection of monosodium urate (MSU) crystals into the metatarsal entheses of wild-type (WT) or oxidative-burst-deficient (Ncf1**) mice. Quantitative variables of inflammation (edema, swelling) and vascularization (tissue perfusion) were assessed by magnetic resonance imaging (MRI), bone-forming activity by [18F]-fluoride positron emission tomography (PET), and destruction of cortical bone and new bone formation by computed tomography (CT). Non-invasive imaging was validated by histochemical and histomorphometric analysis. While injection of MSU crystals into WT mice triggered transient mild enthesitis with no new bone formation, Ncf1** mice developed chronic enthesitis accompanied by massive enthesiophytes. In MRI, inflammation and blood flow in the entheses were chronically increased, while PET/CT showed osteoproliferation with enthesiophyte formation. Histochemical analyses showed chronic inflammation, increased vascularization, osteoclast differentiation and bone deposition in the affected entheseal sites. Herein we describe a fast and reliable effector model of chronic enthesitis, which is characterized by a combination of inflammation, vascularization and new bone formation. This model will help to disentangle the molecular pathways involved in the effector phase of enthesitis.
Inference in Regression Discontinuity Designs with a Discrete Running Variable
Authors: Kolesár Michal , Rothe Christoph
Published: July 2018

We consider inference in regression discontinuity designs when the running variable only takes a moderate number of distinct values. In particular, we study the common practice of using confidence intervals (CIs) based on standard errors that are clustered by the running variable as a means to make inference robust to model misspecification (Lee and Card 2008). We derive theoretical results and present simulation and empirical evidence showing that these CIs do not guard against model misspecification, and that they have poor coverage properties. We therefore recommend against using these CIs in practice. We instead propose two alternative CIs with guaranteed coverage properties under easily interpretable restrictions on the conditional expectation function. (JEL C13, C51, J13, J31, J64, J65)

Representações sobre mulheres nos estádios de futebol
Authors: Andrada Bandeira Gustavo , Seffner Fernando
Published: July 2018

A legitimação masculina nos estádios de futebol faz com que suas práticas apareçam fora de questionamento. O saber aprendido passa por repetidos exercícios de naturalização fazendo com que esses sejam associados a todos os homens que ocupam esse espaço. Esse conhecimento e essa legitimidade do lugar masculino nas práticas torcedoras nos estádios de futebol, do jornalismo esportivo e da atuação no futebol profissional lhes dá, também, a possibilidade de produzir representações sobre as mulheres que atuam nesse espaço. Apresentamos representações sobre mulheres nos estádios de futebol, e como os homens narram essa participação. Utilizamos falas da imprensa esportiva sobre a presença de mulheres no estádio e manifestação de torcedores quando da realização de etnografia na Arena do Grêmio.

Authors: Freitas Junior Miguel Archanjo de , Oliveira Edilson de , Linhares Wendell Luiz
Published: July 2018

O objetivo do estudo foi analisar o papel da família no processo de aprendizagem e reprodução do gosto pela prática futebolística amadora. Para isto, optou-se em utilizar os princípios da Etnografia para estudar a equipe do Mirante E. C., localizada na cidade de Ponta Grossa-PR. Utilizou-se como baliza temporal o período de 2013 a 2017, momento que  observou-se jogos oficiais, peladas (jogos não oficiais), amistosos e também os espaços de socialização dos atletas, totalizando 180 saídas de campo. Nessa análise, identificou-se um imbricamento entre a estrutura familiar e a estrutura do clube, emergindo a necessidade de preservação deste lócus, ou seja, um espaço em que se valoriza a herança cultural futebolística, as trajetórias dos agentes, a coletividade e o próprio lugar.
Negritude futebol clube: pretos, brancos e cinzas
Authors: Bonfim Aira Fernandes
Published: July 2018

A partir da história da equipe de futebol amador Negritude Futebol Clube, time que teve origem na passagem da década de 1970 para 1980 na região de Arthur Alvim em São Paulo, o trabalho observará nessa prática esportiva um potente caso de associativismo comunitário emergente no final dos anos 1970, que inclui os discursos e práticas do movimento negro daquele período, até reflexões atuais. Através de um conjunto complexo de relações sociais, essa experiência de futebol se mostrará responsável pela geração de pertencimento e de senso de comunidade, contrariando a ideia de que esse esporte é, contudo, uma prática alienante.
QUATERNARY BASALTS FROM ROMANIA - CHARACTERISTICS AND NON-CONVENTIONAL USES
Authors: Marica S.
Published: July 2018

This paper presents an advanced stage of research work regarding the exploitation of natural volcanic rocks (basalt, andésites, tuffs) that are not to be polished but that can be cut into thin tiles and be cover with different inorganic and organic films. The basalt, andésite and tuff samples from some quarries proved to have very good cutting parameters, linear thermal expansions with a temperature between 5.67 and 8.85 x106C"1 for basalts and andésites and between 0.05 and 3.82 x106 C"1 for tuffs. The classic ceramic coating process used glaze with grinding fineness. The resulting surfaces are glossy, uniformly covered from a decorative aspect and by a variety of colour, suitable for various external and internal applications. The non-conventional coating by oxy-gas flame thermal spraying process on basalt frits with a grinding fineness between 100 and 70 μπι, resulted in rough, dark coloured surfaces, suitable for floors with high compressive strengths.
REMOVAL OF LEAD (Pb ) AND ZINC (Zn ) FROM AQUEOUS SOLUTIONS BY ADSORPTION ON VERMICULITE FROM ASKOS AREA IN MACEDONIA (NORTHERN GREECE).

Published: July 2018

The lead and zinc removal from their aqueous solutions by vermiculite samples from Askos area, Northern Greece, was studied using a batch type method. Askos vermiculite is mainly consisted of mixed-layer phyllosilicates. A standard vermiculite sample from Kent, Connecticut was also used for comparison reasons. The concentration of the solutions used varied between 100 and 2000mg/L The maximum uptake capacity of the Askos vermiculite for lead and zinc was found to reach 95% and 96% from solutions containing 100mg/L, respectively. Much lower uptake capacities: 37% for lead and 76% for zinc were found for the Kent vermiculite. The experimental results showed that the Askos vermiculite exhibited an acceptable high capacity for removing metal ions from aqueous solutions. Thus, this untreated and low-cost mineral can find use in purifying heavy metal wastewaters. The uptake distribution coefficient (Kd) showed that the relative lead and zinc removal is higher for initial concentrations below 1000mg/L Batch adsorption experiments conducted at room temperature (22±1°C) showed that the adsorption patterns followed the Freundlich isotherm model. The heavy metal (Pb2+, Zn2+) removal is a rather complicated phenomenon related both to the aqueous chemistry of the elements and the interaction of their cationic species with the used materials. The removal procedure can be attributed to different processes such as ion exchange, adsorption, and precipitation.
