Active engagement with stigmatised communities through digital ethnography
Authors: Barratt Monica J , Maddox Alexia
Published: May 2016

Conducting research in the rapidly evolving fields constituting the digital social sciences raises challenging ethical and technical issues, especially when the subject matter includes activities of stigmatised populations. Our study of a dark-web drug-use community provides a case example of ‘how to’ conduct studies in digital environments where sensitive and illicit activities are discussed. In this paper we present the workflow from our digital ethnography and consider the consequences of particular choices of action upon knowledge production. Key considerations that our workflow responded to include adapting to volatile field-sites, researcher safety in digital environments, data security and encryption, and ethical-legal challenges. We anticipate that this workflow may assist other researchers to emulate, test and adapt our approach to the diverse range of illicit studies online. In this paper we argue that active engagement with stigmatised communities through multi-sited digital ethnography can complement and augment the findings of digital trace analyses.
Application of Metal Implant 16-Bit Imaging: New Technique in Radiotherapy
Authors: Xin-ye Ni , Liugang Gao , Mingming Fang , Tao Lin
Published: May 2016

Objective:

This study aimed to evaluate the computed tomography number and the variation of dose distribution based on 12-bit, 16-bit, and revised 16-bit images while the metal bars were inserted.

Methods:

The phantoms containing stainless steel, titanium alloy, and aluminum bar were scanned with computed tomography. These images were reconstructed with 12-bit and 16-bit imaging technologies. The “cupping artifacts” computed tomography value of the metal object revised by Matlab software was called the revised 16-bit image. The computed tomography values of these metal materials were analyzed. Two radiotherapy treatment plans were designed using the treatment plan system: (1) gantry was of 0° irradiation field and (2) gantry was of 90° and 270° for 2 opposed irradiation fields. The dose profile and dose–volume histogram of a structure of interest were analyzed in various images. The analysis was based on the radiotherapy plan differences between 3 different imaging techniques (12-bit imaging, 16-bit imaging, and revised 16-bit imaging technologies).

Results:

For low-density metal object (computed tomography value <3071 Hounsfield unit, HU), the radiotherapy plan results were consistent based on 3 different imaging techniques. For high-density metal object (computed tomography value >3071 HU), the difference in radiotherapy plan results was obvious. The dose of 12-bit was 15.9% higher than revised 16-bit on average for the downstream of titanium rod. For stainless steel, this number reached up to 42.7%.

Conclusion:

A 16-bit imaging technology of metal implants can distinguish the computed tomography value of different metal materials. Furthermore, the revised 16-bit imaging technology can improve the dose computational accuracy of radiotherapy plan with high-density metal implants.
Zygmunt Bauman: On what it means to be included
Authors: Best Shaun
Published: May 2016

Although Zygmunt Bauman has written very little directly about education, his underpinning ideas on the transition from solid to liquid modernity, the mechanisms of social exclusion, the Other and the stranger have had a significant impact on education research. Taking his starting point from a questionable secular reading of Emmanuel Levinas’s contribution to ethics, Bauman’s account of social exclusion has become well respected. The social forces described by Bauman are always external to the individual in Bauman’s social analysis of suffering in that it places no emphasis on the culpability of other human agents as the cause of the Other’s suffering. This article identifies this underemphasis on human agency as a flaw in Bauman’s analysis and evaluates Bauman’s largely ignored and problematic understanding of inclusion, in which social inclusion and exclusion are based on the same mechanisms and identified as two sides of the same coin central for maintaining social solidarity.
Lenin and Utopia
Authors: Renfrew Alastair
Published: May 2016

The demise of the Soviet Union has for the past twenty-five years stood as effective “proof” of the error of utopia. This article returns to an ambivalent source of Soviet utopianism, Lenin's State and Revolution (1917), in order to show how the contradictions inherent in the theory of the state developed there programs no less than the dialectical transformation of Lenin's principled anti-utopianism into a particular form of utopia. This prepares the argument that Soviet ideology and the ostensibly practical politics through which it was mediated are grounded not in Marxism-Leninism or so-called dialectical materialism but rather in a neutralization of the inevitable contradictions of the “actually achieved” spatial utopia by projecting them onto the temporal axis. The essence of Soviet ideology thus lies in the absolute and enduring future projection of present contradictions onto the utopia yet to come. The cult of Lenin disguises the manner in which the “true” utopia of the “withered state” was supplanted by the “false” utopia of the projected “radiant future.” In the process both Lenin and the Soviet utopia become maximally productive experiment fields for all forms of ideologized future projection, rather than one-dimensional “proofs” of the untenability and undesirability of utopian thinking as such.
The Leninist Hypothesis
Authors: Hitchcock Peter
Published: May 2016

Given the collapse of communism and actually existing socialism, we should not be surprised that there have been various attempts to revisit the meaning of V. I. Lenin and Leninism. While political answers have seemed relatively easy, several thinkers, including Alain Badiou, Slavoj Žižek, and Etienne Balibar, have taken up some of the conceptual difficulties in play in Lenin's ideas (and in Mao's) with a view to recasting communism in the present (I take my title, for instance, from Badiou's Communist Hypothesis). This essay addresses both key elements in this rethinking (such as concepts of repetition and event) and an exegesis of what remains, and remains to be elaborated, in the utopianism of Leninism. I am particularly interested in the force of Fredric Jameson's call for “anti-anti-utopianism” in understanding the aesthetic and political processes of “repeating Lenin” in cultural theory and practice. Ultimately, the attempt is to assess the impetus of such utopianism in articulating futurity.
Bestowing Past and Future: The Given as Foreclosure in Marion, Derrida, and Nancy
Authors: Trimm Ryan
Published: May 2016

Givenness frequently forecloses the future; however, the term has a complex legacy through both economic accounts of the gift and phenomenological explorations of the given. Jean-Luc Marion, Jacques Derrida, and Jean-Luc Nancy all invoke both gift and given; however, their formulations of givenness differ strikingly with regard to temporality. Marion conceives the given as revelation, a vision summoning (and thus preceding) the givee. Derrida thinks of the given as an inheritance received from the future and thus responsible to what is to come. Nancy locates the given in the present but finds givenness to be the mutual relation and imbrication of beings, a web of entanglement that spaces but does not determine those beings.

In the modern dynamically developing society the content of the concept "literacy" has considerably extended. Functional literacy acts as the way of social orientation of the personality integrating education communication (fi rst of all, the general) with multidimensional human activity. In article approaches to formation of functional literacy of the calls of information society which are trained taking into account variety are considered. It is noted that the condition of the information environment of modern society is considerably caused by rapid development of mass media and domination of a phenomenon visual in general. It is about ability of any educated person to build a complete number of communication of any scale (up to global) by the principle of a semiotics variety, freedom of sign expression of information. Explosive development of technical means of information transfer, volumes of the generated data and the new communicative condition of activity of the person having planetary scale aren´t followed by high-quality shifts in development in the trained functional skills in system of the personal, interpersonal and public relations.

Sensor Fiber Optik Dari Bahan Fiber Optik Polimer Untuk Pengukuran Refractive Index Larutan Gula
Authors: Sari Nila Wulan , Marzuki Ahmad , R Riyatun
Published: May 2016

This paper presents an experimental result on developing an optical fiber sensor for measuring refractive index of sugar solution. Sensor was developed using polymer optical fiber with diameter of 3 mm. This sensor is working based on intensity modulation due to reflection. Light coming out from the transmitter optical fiber is reflected by a mirror to the receiver optical fiber. Due to the variation of sugar concentration in solution surrounding this sensor, the way of light entering the fiber receiver depends on the sugar concentration (numerical aperture). It is clear from the experiment that light intensity detected by photodetector (represented by electric voltage) is linearly dependent (R2 = 0.987) on the variation of sugar solution refractive index.

Published: May 2016

An infant incubator utilizing a non-electrical heater element and an add-on temperature and relative humidity controlling unit has been produced. Copper pipe in planar spiral construction which usually found as a radiator element in refrigerator was used as the heater element. Once the hot water filled into the element, it will served as heat energy source for (40 x 58 x 40) cm3
volume of incubator’s baby compartment. Compartment’s performance (P) in providing the heat energy was to be found as 0.4 J/s and the average constant temperature achievable was 34.2 oC. Two of LM35 ICs were operated as dry and wet sensor each and served as the input for temperature and humidity quantities for baby’s compartment. These both sensors were set by CV-AVR package program which then was loaded into the ATMega8535 chip. An LCD
screen of 20x2 matrices was then used in displaying these both quantities. Dry and wet temperature sensors which were used to acquire the value of air temperature and relative humidity within baby’s compartment to be found have sensitivity value of 0.02 0.01 volt/oC and 0.03 0.01 volt/oC, each.

Published: May 2016

Magnetic nanoparticles of cobalt ferrite (CoFe2O4) have been synthesized by co-precipitation method with various synthesis temperature and concentration of NaOH. The structural characteristics and particle size of CoFe2O4 were determined by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM), its showed that nanoparticles well crystallized with various grain size which depend on synthesis parameters. The grain sizes estimated using the Scherrer formula were found that the grain size increased with increasing temperature synthesis and decreasing concentration of NaOH. Magnetic characterization of CoFe2O4 nanoparticles was investigated by using a Vibrating Sample Magnetometer (VSM). Sample with various concentration of NaOH showed that coercivity was decrease with the decrease of particle size. In other hand, samples with various synthesis temperature found that sample with
smallest grain size have high coersivity. The saturation magnetization increase when crystallinity increase. Based on the results, it can be concluded that magnetic characterization of CoFe2O4 was influenced by grain size and crystallinity.

Published: May 2016

Barium ferrite with hexagonal molecular BaFe12O19 is well-known for its high performance permanent magnetic and good mechanical properties and attracted attention of researchers for a long time. The hexaferrite powders were produced according to a conventional ceramic process with powder metallurgy method. Moreover, the powders were analyzed by X-ray diffraction, to detect the presence of secondary phases. The magnetic properties of the samples were measured at room temperature using Permeagraph with a maximum applied field of 1.5 T. The calculation of the lattice parameter on conventional magnets (BaFe12O19) results a = b = 5,894 Å and c = 23,210 Å, while the substituted phase has a range value of a = b between 5,893 Å to 5,899 Å, and c lattice parameter value is in the range of 23,328 ˚A to 23,346 Å. With the partial substitution of Fe+3 ions by Mn+2 ions, ion Co+2 and Ti+4 ion magnetic
properties decrease primarily on the magnetic coercivity from 125 kA / m (conventional) to ~ 5 kA /m in the substituted materials.

Efek Annealing Temperture Terhadap Sifat Magnetik Dan Struktur Multilapisan Tipis Cobalt-Samarium
Authors: E Erwin
Published: May 2016

Multilayer thin films of cobalt and samarium with the structur of 20[Co (4.2 nm)/Sm (3.8 nm)] have been fabricated using dc magnetron sputtering technique. Crystalline formation due to heat treatment of about 450oC of the sample is responsible for increase of coercivity from 300Oe to 3500 Oe. Due to heat treatment (annealing) of the sample caused the value of the magnetization of the sample decreases. This is due to the formation of none magnetic phase in
interfacial mixing between the layers as a result of inter-diffusion between the layers. Structural properties of as deposited and annealed samples was studied using transmission electron microscope (TEM). Electron diffraction patterns for as deposited sample exhibit diffused rings for samarium reflection however, for the annealed sample of about 450oC for 30 minutes produces sharp diffraction rings. This indicates that alloys of CoSm in interfacial mixing has a crystalline properties. By modifying the annealing temperature and time one can obtain higher value of coercivity of alloy of CoSm between the layers as one of the
requirements for higher density magnetic recording media.

The bombing of Guernica in documentary film: Art and anniversary as discursive elements
Authors: Cueto Asín Elena
Published: May 2016

This article examines the way in which the April 1937 bombing of Guernica has been represented, either as an isolated episode or as part of the broader development of the Spanish Civil War, in documentaries created in regional, national and international production contexts. It draws attention to the techniques used in these films, mostly made for television, to reach viewers that – since they belong to multiple interpretative communities – are bound to understand the war in different ways. The study considers some of the ways in which the relationship between this historical event and Pablo Picasso’s Guernica both memorializes and universalizes the episode as a discursive element. I argue that this process contributes to framing events of the past both independently and as part of a cycle of commemorative junctures that comprise a regular schedule of anniversaries.
Revolutionizing the ‘national means of expression’: The influence of Soviet film culture in pre-Civil War Spain
Authors: Fibla Gutierrez Enrique
Published: May 2016

This article examines the influence of the USSR on the film culture of 1930s Spain. It focuses on the years before the Civil War, researching the role that Cominternaligned initiatives had on Spanish non theatrical educational and political filmmaking, as well as institutional developments associated with these movements. It analyses the complex dynamics of representation fostered by film as a tool for cultural and social progress, in a country that was desperately seeking new models of political organization and modernization. In particular, I explore how cultural exchanges with the USSR were mediated through film journals, film-clubs, festivals and congresses, fostering nationalist and internationalist imaginaries in which the interests of very different social actors paradoxically converged. Ultimately, the article explores how the introduction of Soviet aesthetics in Spain by a group of intellectuals since the late 1920s paved the way for the radicalization of the Spanish cultural landscape during the Civil War.
Conduits for transformation: Spatializing the essay, towards an embodied pensiveness
Authors: Glisovic Smiljana
Published: May 2016

This article traces a connection between the literary essay and the audio-visual installation in order to consider how a spatialization of the essay can create the conditions for affective experience. The composition of the audio-visual installation can condition an environment for an embodied pensiveness where the moving image and sound act as conduits towards affective transformation. I discuss essayistic architectures in relation to poetic structures and ways in which both, through their play of associations, can access spaces where language cannot articulate fully. I use as a case study my audio-visual installation, Straying, to discuss how this approach was particularly useful in exploring the relationship between body and environment, the making and unmaking of the self in relation to the places we inhabit. The space of the installation is a transformative and transformational space, where the audience and work make and unmake one another through meandering of thought/body instigated by the dynamics between image, screen, space and sound.
Thinking through the screenplay: The academy as a site for research-based script development
Authors: Batty Craig , Sawtell Louise , Taylor Stayci
Published: May 2016

Script development is a creative, commercial and social process in which ideas, emotions, people and personalities combine, cohere, clash and are contested by the practicalities, policies and rapid movements of the screen industry. It is an activity often controlled by hierarchical and financial powers, yet experienced by individual and usually sensitive practitioners trying to tell their stories to an outside world. Script development is a highly exciting yet potentially very daunting aspect of screen production and in recent times has crept into the university, with academics and academics-in-training developing screenplays for research projects and degrees. In this article we discuss and provide examples of the academy as a site for researchbased script development, an activity that draws on creative practice research methodologies to find ways of conceiving and executing screenwriting differently. By taking away the commercial constraints of the industry and instead incubating ideas in a research environment, we consider the potential of the screenwriter to use the academy as a space in which their practice can be broadened, deepened, expanded and experimented with. While this practice might sit outside of the industry while in process, we see its results as having the future potential to be used in – or at least valued by – that very industry. As creators, writers, storyliners and script editors of a range of screen works across a range of industry settings, we draw here on our collective screenwriting practice experiences within the academy to focus on the notion of thinking through the screenplay – using research to underpin creative practice, resulting in what we might call an ‘academic screenplay’ – as a way of writing differently for the screen.
Being a human being and how art can help
Authors: Wienk Janeke
Published: May 2016

Based on the author’s experience, this Interlude explores the different ways in which art can help reflect on artistic, pedagogical and existential key questions that are relevant to both personal and professional contexts. The lived experience of how being in touch with art helps one to be in touch with one’s own humanity can be a powerful starting point to art education. This Interlude aims to bridge the gap between an instrumentalized arts curriculum and the natural ability of art to connect us to the very base of human existence.
Coronary Artery Dissection in the Left Main Treated with Stenting in a Patient with Multiple Re-infarction – Case Report
Authors: Nyulas Tiberiu , Blendea Ciprian , Barcan Andreea , Bajka Balazs , Korodi Szilamer , Rat Nora
Published: May 2016

Introduction: In complex cases of multiple coronary artery stenosis, revascularization strategy could be essential for improving the life expectancy and quality of life. However, major complications are sometimes encountered during interventions, such as rupture of the atheromatous plaque with consequent dissection of the coronary artery, causing an acute coronary syndrome which requires immediate intervention from the operator. In the absence of an experienced interventional cardiologist a complication like this can be fatal.

Case presentation: We present the case of a 67-years old patient, male, with a known history of cardiovascular disease, who presented in our service complaining of chest pain with tightening character, irradiation in the shoulder and left arm, respectively shortness of breath and fatigue. The patient presented a history of multiple infarctions, intervention and stenting on RCA and circumflex artery. Computed Tomographic Coronary Angiography provided detailed information on the location of the target lesions and was followed by a revascularization procedure. However, despite the complex pre-interventional assessment, while trying to engage the guide in the emergence of the circumflex artery, atherosclerotic plaque rupture occurred, causing a dissection of the coronary wall which extended retrogradely into the left main, requiring a rapid response from the operator. A coronary stent was implanted into the left coronary artery trunk, treating the dissection.

Conclusions: Coronary artery dissection is a very serious complication that can occur during a complex revascularization procedure, requiring immediate intervention in order to save the patient’s life.

Published: May 2016

Objective: In this study we report the development of a simple, rapid and efficient capillary electrophoresis method for the simultaneous determination of atorvastatin, fluvastatin, lovastatin and simvastin.

Methods: Capillary zone electrophoresis proved to be efficient for the simultaneous separation of atorvastatin and fluvastatin, but could not resolve the determination of lovastatin and simvastatin. The simultaneous separation of all four statins was achieved by applying a micellar electrokinetic chromatographic method, after transforming lovastatin and simvastatin in β-hydroxyl acid forms through alkaline hydrolysis. The optimum electrophoretic conditions and analytical parameters were investigated and the analytical performances of the method were verified with regard to linearity, precision, accuracy, LOD and LOQ.

Results: The optimum electrophoretic separation conditions were: 25 mM sodium tetraborate with 25 mM sodium dodecyl sulphate buffer electrolyte at pH 9.5, applied voltage + 25 kV, separation temperature 25 °C, injection pressure/time 50 mbar/1 minutes, UV detection at 230 nm. Using the optimized electrophoretic conditions we succeeded in the simultaneous determination of the four statins in approximately 3 minutes, the order of migration being: atorvastatin, fluvastatin, lovastatin, simvastatin. The proposed method has been applied to the determination of the analytes in pharmaceutical tablets formulations.

Conclusions: The capillary electrophoretic method developed in the present work proved to be suitable for the routine analysis of statins and can be adopted as quality control protocol in pharmaceutical analysis.

Published: May 2016

Objective: The aim of the study was to describe clinical and laboratory characteristics in HIV-infected patients with Kaposi sarcoma (KS).

Methods: We retrospectively studied data on HIV-infected patients hospitalized in one tertiary care hospital in Bucharest, Romania, in whom Kaposi Sarcoma was diagnosed, between January 2008 and November 2013.

Results: We identified 27 HIV-infected patients diagnosed with KS within 6 years. They had a median age of 42 years old and a median CD4 cell count of 101 cells per mm3 at the time of KS diagnosis. All patients received antiretroviral therapy (ART), with 18 patients (66%) already on ART at the time of KS diagnosis. Most patients (59%) were classified as ACTG poor-risk and 56% as Mitsuyasu stage I. The overall prognosis was poor, with 41% mortality, in a median time span of 6 months, significantly correlated with gastrointestinal involvement (p=0.019), poor-risk KS in ACTG classification (p<0.001) and stage IV Mitsuyasu (p=0.006).

Conclusion: KS remains an important cause of morbidity and mortality in patients with HIV infection, especially in late presenters.
The Importance of Home Versus 24-Hour Ambulatory Blood Pressure Monitoring and Assessment of Blood Pressure Variability in Hypertension
Authors: Magdás Annamária , Belényi Boglárka , Gaburoi Adina , Incze Alexandru
Published: May 2016

Background: A number of studies reveal that home blood pressure variability is associated with cardiovascular risk factors. However, we do not have a consensus regarding the variability index and the frequency of measurements.

Objective: The aim of the study was to assess home blood pressure variability for a period of 7 consecutive days and 24-hour ambulatory blood pressure variability using the average real variability index and to test whether home blood pressure variability represents a suitable parameter for long-term monitoring of the hypertensive patients.

Material and methods: A number of 31 hypertensive patients were included in the study, 8 male, 23 female, mean age 60.19±7.35 years. At the inclusion ambulatory blood pressure monitoring was performed, home blood pressure monitoring was carried out for 7 consecutive days with 2 measurements daily. We compared ambulatory blood pressure values, variability using paired t-test. We were looking for correlations between HBP values and cardiovascular risk factors.

Results: Ambulatory versus home blood pressure derived mean blood pressure was 131.38±15.2 versus 131.93±8.25, p=0.81. Ambulatory derived variability was 10.65±2.05 versus home variability 10.56±4.83, p=0.91. Home versus ambulatory pulse pressure was 51.8± 9.06 mmHg vs. 54.9±11.9 mmHg, p=0.046. We found positive correlation between HBPV and home BP values, p=0.027, r2=0.1577, (CI: 0.04967 to 0.6588). Home, as well as ambulatory derived variability were positively correlated to age p=0.043, r2=0.1377 (CI: 0.01234 to 0.6451) versus p<0.0001, CI: 0.3870 to 0.8220, r2=0.4302.

Conclusion: Assessment of home blood pressure monitoring and variability could represent a well-tolerated alternative for long-term follow-up of hypertension management.
Pulmonary and Cerebral Infarcts Due to Secondary Thrombosis Risk of a Genetic Mutation: Life-threating Methylentetrahydrofolate Reductase (MTHFR) Deficiency with Early Onset
Authors: Ianosi Edith Simona , Simona Szasz , Nemes Roxana , Jimborean Gabriela
Published: May 2016

Methylentetrahydrofolate reductase (MTHFR) is a key enzymatic component of the folate cycle, converting 5,10-methylentetrahydrofolate into 5-methylentetrahydrofolate. Severe MTHFR deficiency is a rare recessive disease leading to major hyperhomocysteinemia, homocystinuria, and progressive neurological distress within the two first decades of life.

We present the case of a young, 21 years old female patient who was admitted and treated in Clinic of Pneumology Tirgu Mures for a posterobasal left pneumonia without favourable radiologic evolution under antibiotic and symptomatic treatment. Thoracotomy was recommended in order to elucidate the diagnosis. The histopatological examination revealed the zone of pulmonary infarction. After 12 weeks from surgical intervention, the patient was admitted in Department of Neurology for stroke attack. The complex laboratory investigations reveal deficiency of methylentrahydrofolate reductase (MTHFR) caused by a genetic mutation.

Published: May 2016

The influence of water pH and cationic surfactant content on the interfacial properties and stability of an Algerian bitumen aqueous emulsion were investigated. While the stability was quantified by both the test-bottle method and size distribution measurements, the interfacial properties of the water–bitumen interface were assessed using interfacial tension measurements. Optical microscopy was also used to visualise the dispersed water droplets in the oil phase. The results showed that addition of the cationic surfactant at a concentration of 25 mmol L

Thiophene-free diphenyl-amino-stilbene-diketo-pyrrolo-pyrrole derivatives as donors for organic bulk heterojunction solar cells
Authors: Honová Jana , Luňák Stanislav , Vala Martin , Stříteský Stanislav , Fekete Ladislav , Weiter Martin , Kovalenko Alexander
Published: May 2016

An extended study on a group of four soluble diphenyl-amino-stilbene based diphenyl-diketopyrrolo-pyrrole molecules has been carried out. Using the materials in thin-film transistors it was shown that the above-mentioned compounds can be successfully used as donors in organic photovoltaic devices. Influence of the molecular symmetry and solubilizing chain on the morphology and solar cell performance are described. It was shown that a shorter and non-branched ethyl acetate chain leads to higher charge carrier mobility, short circuit current, and better fill factor. After the basic optimization, a power conversion efficiency of about 1.5 % was reached. This, to the best of our knowledge, is the highest reported efficiency of thiophene-free small-molecule diketo-pyrrolopyrroles.
Positive youth development and academic behavior in Chinese secondary school students in Hong Kong
Authors: Shek Daniel T.L. , Wu Florence K.Y.
Published: May 2016

With the launching of the education reform in Hong Kong, the secondary school structure was changed from 7 years to 6 years in the 2006–07 school year. This paper describes Secondary four students’ views about the new secondary school curriculum, including their confidence and related stress. The students were also asked to assess the importance of life skills and its perceived adequacy in the formal curriculum. Results showed that roughly four-tenths of the students did not feel confident about their study and around six-tenths felt stressed. Although most of the students agreed that life skills were important, around 37% of them thought that the coverage of such knowledge in the formal curriculum was not adequate. Consistent with our hypotheses, academic confidence, academic stress, support provided by the school, and positive youth development were significantly related, with positive youth development predicting academic confidence.
Unvollständige Professionalisierung und Konflikte im Bereich der Sozialarbeit / Incomplete Professionalization and Conflicts in Social Work
Authors: Blinkert Baldo
Published: May 2016

Since long one can observe definite tendencies to professionalize the role of social workers. In a research project will be investigated with which type of unplanned consequences these tendencies are connected. The research will be concluded towards the end of 1972. The following hypotheses will be tested: (1) The lesser the possibilities to integrate practical procedures into the professional base of knowledge, the greater the loss of plausibility of the professional role at the beginning of the professional career. (2) The greater the incompatibility between expectations for control and structures of control performance, the more conflicts will occur in welfare organizations. (3) Patterns of adaptation will be adopted in the course of the professional career which enable a settlement of the discrepancies between occupational expectations of the social worker and restrictions of his organization. Such patterns of adaptation are the following: avoidance, organizational innovation, immunization of the base of knowledge and acceptance of bureaucratic role interpretations.
Zurechnung von Beförderungen im öffentlichen Dienst / The Attribution of Promotions Among Civil Servants
Authors: Luhmann Niklas
Published: May 2016

Within the framework of an empirical investigation in the civil service of the Federal Republic of Germany, interviews were conducted with civil servants with a view to determining (with the aid of an abbreviated measurement scale) whether they were generally more inclined to attribute events to an internal or to an external locus of control; in addition, the interviewees were asked specifically in which of these directions they were wont to locate the causes of their own promotions and those of their colleagues. - In its approach, the investigation was based on the attribution model developed by HEIDER, JONES, HECKHAUSEN, and others. The present paper reports on the study’s findings, and relates them to general problems of rational allocation of personnel in large-scale organizational systems.
Empirische Analyse komplexer kognitiver Strukturen / Empirical Analysis of Complex Cognitive Structures
Authors: Weymann Ansgar
Published: May 2016

Several theoretical approaches emphasize the relevance of empirical research of cognitive structures to the analysis of social action. In this theoretical context two proper empirical techniques of cognitive analysis are discussed: ethnoscience and experimental psycholinguistics. Their integration would connect the validity of the first and the reliability of the second.
Biographical Method in Polish Sociology / Zur biographischen Methode in der polnischen Soziologie
Authors: Bukowski Jacek
Published: May 2016

Die Forschungsmethode via persönlicher Dokumente: die Verwendung subjektiv-authentischer Lebensaufzeichnungen zu Zwecken der Analyse sozialer Prozesse und der Persönlichkeitsentwicklung, hat im Rahmen einer humanistischen Soziologie einen anerkannten Platz gefunden. Sie ist weitgehend in Polen begründet worden. Die positiven Erfahrungen, die mit dieser Methode gemacht, und die guten Ergebnisse, die mit ihr in der polnischen Soziologie erzielt werden konnten, werden in diesem Beitrag um so berechtigter vorgestellt, als die biographische Methode in Polen nunmehr auf eine fünfzigjährige Tradition zurückblicken kann. Der Autor gibt ein zunächst allgemeines, die Hauptannahmen dieser Methode betreffendes Bild. Die Vorkriegsperiode steht hier insofern im Vordergrund, als sie ihre Ursprünge und zugleich größten Erfolge markiert. Daran anschließend werden die Versuche behandelt, die Methode auch im Sinne der neueren Forschungsentwicklung einzusetzen; wie sich zeigt, haben sich willkommene und fruchtbare Korrespondenzen ergeben. Die Gesichtspunkte und Überlegungen, die in der Arbeit zur Sprache kommen, nehmen dabei hauptsächlich auf polnische Soziologen - wie JOZEF CHALASINSKI, JAN SZCZEPANSKI und andere - Bezug, die an der Methode biographischer Dokumentierung besonderes Interesse zeigen. Der Autor dieses Beitrags stützt sich so in hohem Maße auf Publikationen (zustimmender oder kritischer Art), wie sie in der neueren polnischen Soziologie vorliegen. Viele Überlegungen gehen natürlich auf ihn selbst zurück; so stellt er nach zweijähriger Arbeit an diesem Problem bestimmte, wenn auch wenige Mängel fest: eine Reihe gescheiterter, aber schließlich auch erfolgreicher Versuche, zum Problem biographischen Materials als einer Quelle soziologischer Forschung eine neue Plattform zu gewinnen.
Autonome Wissenschaft: Überlegungen zu einer Fiktion / The autonomy of science: Reflections about a fiction
Authors: Fach Wolfgang
Published: May 2016

The autonomous character of science - its ‚genuine‘ scientific character - can only be guaranteed, if one arrives at a consistent formulation of an exclusive purpose of science and a functional methodology. The most thoroughgoing attempts at solving this complex problem have been undertaken in the context of ‚critical rationalism‘, in particular by POPPER and LAKATOS. It can be shown, however, that both attempts fail in every respect. Their purpose to constitute science as a self-regulative system and to make it ‚waterproof‘ with respect to social and individual influences of all kind, ends up in logical fallacies, theoretical contradicitions, or metaphysical postulates.
Toward a Theoretical Understanding of Ethnic Antagonism: The Case of the Foreign Workers in Switzerland / Zum theoretischen Verständnis ethnischer Konflikte: Der Fall der ausländischen Arbeitnehmer in der Schweiz
Authors: Wallimann Isidor
Published: May 2016

Der Import ausländischer Arbeitskraft (vor allem aus Südeuropa) ist für die nordeuropäischen Länder in der Zeit nach dem zweiten Weltkrieg zum gemeinsamen Merkmal geworden. Ein vorrangiges Beispiel ist die Schweiz. Die Probleme, die mit dieser Wanderung von Arbeitskraft verbunden sind, sind vielfältiger Natur. Zu den Hauptproblemen gehört die Diskriminierung ausländischer Arbeitnehmer durch die einheimische Bevölkerung. Die Ursprünge dieser Diskriminierung können theoretisch mithilfe tauschtheoretischer Prämissen - und unter Beachtung der Konsequenzen, die Wettbewerb auf dem Arbeitsmarkt nach sich zieht - erklärt werden. Im Rahmen einer derartigen Analyse kann zugleich gezeigt werden, in welcher Weise die verschiedenen Formen von Diskriminierung, wie sie Institutionen oder Organisationen implizieren, mit jenen, die Individuen ausüben, funktional verbunden sind. Sollen Diskriminierung, ihre Ursprünge und Folgen verstanden werden, sind alle Formen von Diskriminierung zugleich im Auge zu behalten. Der vorliegende Artikel zeigt, wie dies zu gewährleisten ist.
Wer hat Zugang zur indischen Universität? / Who has access to Indian universities?
Authors: Aich Prodosh
Published: May 2016

Indian educational policymakers and responsible educationists in India are generally convinced that educational institutions at all levels have been opened for traditionally underprivileged groups after the achievement of national independence. This belief is systematically being reinforced by publications of national and foreign scholars. Experts agree that the standard of education at the Indian universities is continuously deteriorating as a result of an increasing number of ‘new students’ who have no tradition in learning. The survey presented here has been conducted at four universities including all students in their final year. The data show that the structures of colonial privilege continue to exist even after 20 years independence, as far as the chances for access to university are concerned. The privileged social background has, however, no influence on positive academic achievement. In other words, the ‚new students‘ are not responsible for the declining standard. A critical analysis reveals that the convictions mentioned above are parts of the ruling class ideology in present India.
„Soziale Indikatoren“ in der Bundesrepublik Deutschland? / “Social Indicators” in the Federal Republic of Germany?
Authors: Kaufmann Franz-Xaver
Published: May 2016

Although the notion of social indicators became a topic of scientific discussion in the Federal Republic of Germany only in 1971, there are today already quite a number of publications as well as research projects centering on this new concept. Research workers and authors, respectively, of these have joined together in the ‘Social Indicators’ Section of the German Sociological Association. The present report underlines the necessity for scientists, administrators, and politicians, to co-operate on the task of developing this new measuring tool; it also discusses some of the difficulties connected with this venture.
