miRNAs, a subclass of non-coding small RNAs, are about 18-22 nucleotides long. It has been revealed that miRNAs are responsible many diseases such as cancer. Therefore, great efforts have been made recently by researchers to explore possible relationships between miRNAs and diseases. Experimental studies to identify new disease-associated miRNAs are very expensive and at the same time a long process. Therefore, to determine the relationships between miRNA and disease many computational methods have been developed. In this paper, a new method for the identification of miRNA-disease associations based on space projection and label propagation (SPLPMDA) is proposed. The forecast the precision of SPLPMDA was demonstrated using 5-fold cross-validation and LOOCV techniques. Values of 0.9333 in 5-fold cross validation and 0.9441 in LOOCV were obtained. Moreover, case studies on breast neoplasms and lymphoma were performed to further confirm the predictive reliability of SPLPMDA.

MicroRNA (miRNA) molecules, which are effective in the formation and progression of many different diseases, are 18–22 nucleotides in length and make up a type of non-coding RNA. Predicting disease-related microRNAs is crucial for understanding the pathogenesis of disease and for diagnosis, treatment, and prevention of diseases. Many computational techniques have been studied and developed, as the experimental techniques used to find novel miRNA–disease associations in biology are costly. In this paper, a Kernelized Bayesian Matrix Factorization (KBMF) technique was suggested to predict new relations among miRNAs and diseases with several information such as miRNA functional similarity, disease semantic similarity, and known relations among miRNAs and diseases. AUC value of 0.9450 was obtained by implementing fivefold cross-validation for KBMF technique. We also carried out three kinds of case studies (breast, lung, and colon neoplasms) to prove the performance of KBMF technique, and the predictive reliability of this method was confirmed by the results. Thus, KBMF technique can be used as a reliable computational model to infer possible miRNA–disease associations.

In this study, the morphometric characteristics of Mount Ararat which is a strato-volcano are analyzed. Türkiye’s highest Mountain, Mount Ararat, is located in Eastern Anatolia. The Mountain takes the shape of two major volcanic cones after 2500 m height; these volcanic cones are named Greater Mount Ararat (5137 m) and Little Mount Ararat (3896 m). In this study, relief morphometry, basin morphometry, and drainage characteristics are morphometrically analyzed with Geographic Information Systems (GIS) using 10x10 m resolution Digital Elevation Model (DEM). According to the analysis results, there is an increase in the elevation on the high and steep slopes of the main cone and the slope values increase up to 56° in some locations towards the summit. On the other hand, according to the aspect analyses, 19.9% of slope faces are north-east direction, 14.7% of the slopes are north-direction, 9.4% are northwest, 9.8% are west, 10.7% are southeast, and 16.4% of the slopes are east direction. These results support the fact that Mount Ararat extends in NW-SE direction and is formed on the basis of a fault line in this direction. According to the grouping made by the altitude ranges analysis, the decrease in the rate of elevation belts starting from the slopes of the mountain towards the top confirms the structure of volcanic cone. Elevation differences in relative relief analyses range between 0 and 1141 m and this value increases to 1141 m on the slopes surrounding the summit. The cone structure of Mount Ararat was prominent in transverse and longitudinal profile analyses.

In this paper, an alternative selective dry etching of p-GaN over InAlN was studied as a function of the ICP source powers, RF chuck powers and process pressures by using inductively coupled plasma reactive ion etching (ICP RIE) system. A recipe using only BCI3-based plasma with a resulting selectivity 13.5 for p-GaN in respect to InAlN was demonstrated. Surface roughness measurements depending on the etching time was performed by atomic force microscope (AFM) measurement and showed that a smooth etched surface with the root-mean-square roughness of 0.45 nm for p-GaN and 0.37 nm for InAlN were achieved. Normally-off p-GaN/InAlN HEMT devices were fabricated and tested by using the BCI3-based plasma we developed.

The topography is inclined and upright, excessive rainfall in the summer increase and filling of stream beds with settlement, the Fatsa (Ordu) district center and the near circumference is increasingly exposed to more stones in recent years. For this reason, the frequency rate method, analytical hierarchy process and logistic regression models were used so that torrent and flooding areas can be formed correctly and consistently. Flood areas were obtained from AFAD and the General Directorate of Meteorology. Flood hazard prediction models were created with 11 independent variables affecting the floods. Accordingly, 19.5 km2 according to the frequency ratio method, 30.7 km2 according to the analytical hierarchy process and 14 km2 according to the logistic regression model were calculated as a high and very high risk flood area. These fields correspond to the Fatsa County Center and Valley floor where the population and settlement are intensive. The model with the highest accuracy rate of three methods used in the study is the frequency rate method (95.9%). However, the flood hazard estimated map, created with the logistic regression model, is calculated to be more accurate than other methods as a result of land observations. It is necessary to give priority to the prevention and improvement of floods in the settlements in the course of the rivers., Topografyanın eğimli ve dik olması, yaz aylarında meydana gelen ekstrem yağışlar ve dere yataklarında yapılaşmanın artışı nedeniyle Fatsa (Ordu) ilçe merkezi ve yakın çevresi son yıllarda giderek daha fazla taşkına maruz kalmaktadır. Bu nedenle taşkın yayılış alanlarının doğru ve tutarlı bir şekilde oluşturulabilmesi için frekans oran metodu, analitik hiyerarşi süreci ve lojistik regresyon modelleri kullanılmıştır. Taşkın alanları AFAD ve Meteoroloji Genel Müdürlüğünden elde edilmiş, taşkını etkileyen 11 bağımsız değişkenle taşkın tehlike tahmin modelleri oluşturulmuştur. Buna göre frekans oran metoduna göre 19,5 km2, analitik hiyerarşi sürecine göre 30,7 km2 ve lojistik regresyon modeline göre 14 km2 alan, yüksek ve çok yüksek riskli taşkın alanı olarak hesaplanmıştır. Bu alanlar nüfus ve yerleşmenin yoğun olduğu Fatsa ilçe merkezine ve vadi tabanlarına karşılık gelmektedir. Çalışmada kullanılan üç yöntemden en yüksek doğruluk oranına sahip model, frekans oran metodudur (%95,9). Ancak arazi gözlemleri neticesinde lojistik regresyon modeli ile oluşturulan taşkın tehlike tahmini haritası, diğer yöntemlere göre doğruya en yakın olduğu tespit edilmiştir. Akarsu mecrasındaki yerleşim alanlarında taşkınların önlenmesi ve iyileştirilmesi için öncelik verilmesi gerekmektedir.

Türkiye’de kırsal alanlar, kentler kadar olmasa da önemli bir dönüşüm süreci içindedir. Bu süreçte kırsal alanlar arazi kullanımı, iktisadi yapı ve yaşam tarzları gibi birçok açıdan değişmektedir. Değişimin önemli göstergelerinden birisi de kırsal konutlardır. Kentsel saçaklanmaya benzer şekilde yerleşim özeklerinden uzaklaşan kırsal konutlar, yerleşme dokusunun giderek daha gevşek/dağınık hale gelmesine neden olmaktadır. Böylece mevcut tarım/hayvancılık arazileri ve tabii unsurlar da değişip dönüşmektedir. Kırsal alanların bir bütün olarak yaşadığı değişim/dönüşüm süreci literatürde ‘yeni kırsallık’ olarak kavramsallaştırılmaktadır. Yeni kırsallığın göstergelerinden mobilitenin/hareket serbestliğinin artmasıyla ortaya çıkan, yılın farklı dönemlerinde kırda ve kentte kalınan ‘ikili yaşam’ biçimi ile kırsalda ‘kentsel yaşam tarzının’ benimsenmesinin etkisiyle, sayfiye evlere ve kırsalda ikinci konuta yönelik talep artmıştır. Böylece kentlere yakın araziler başta olmak üzere ve genel olarak kırsal alanlarda ana ulaşım akslarına yakın kesimlerde daha fazla konut yapılmaktadır. Yeni yapılan bu konutların yerlerinin seçiminde coğrafi verilerin kullanılmasıyla, uygunluk analizleri yapmak ve projeksiyonlar oluşturmak mevcut tarım alanlarının geleceği ve kırsal planlanma açısından önemlidir. Farklı metotlar üzerinden yapılan yer seçimi analizleri, hem metotların birbirlerine göre avantajlarını göstermekte hem de daha doğru analizlerin yapılmasını sağlamaktadır. Bu çalışmada yer seçimi uygunluk analizleri için Lojistik Regresyon (LR), Analitik Hiyerarşi Süreci (AHS) ve Frekans Oran (FO) metotları kullanılmıştır. Çalışma sahası olan Keban Çayı Havzası, Elazığ ilinin kuzeybatısında, Keban ilçesi sınırları içinde bulunmaktadır. Havza yaklaşık 187 km2 ’lik bir yüzölçümüne sahiptir. Sonuç haritalarına göre havzada yeni kırsal konut yapımına çok uygun, ortalama 12,5 km2 arazi olduğu tespit edilmiştir. Her modelin kendine göre avantajları olsa da, LR ve FO metotlarının, AHS’ye göre daha uygun sonuçlar verdiği tespit edilmiştir., Rural areas in Turkey are undergoing significant transformations, but not as much as cities. Rural areas are evolving in many aspects, including land use, economic structure, and lifestyles. Rural housing is one of the most important indicators of change. The migration of rural dwellings from settlement centers causes the settlement pattern to loosen and disperse, similar to urban sprawl. Thus, existing agricultural/livestock lands and natural elements are changing and transforming. The change/transformation process that rural areas undergo as a whole is conceptualized as “new rurality” in the literature. The adoption of the “dual lifestyle” and the “urban lifestyle” in the countryside, which are indicators of the new rurality, has increased the demand for “country residence” and “second homes” in the countryside. Thus, more housing is being built in areas near major transportation axes, particularly near cities and in rural areas. Making suitability analyses and creating projections by employing geographical data in the selection of the locations of these newly built houses is important for the future of existing agricultural areas and rural planning. Performing site selection analyses with different methods demonstrates the advantages of one method over the others and provides more accurate analyses. In this study, logistic regression (LR), analytical hierarchy process (AHP), and frequency ratio (FO) methods were used for site selection suitability analysis. The study area, Keban Stream Basin, is located in the northwest of Elazig, within the borders of the Keban district. The basin has a surface area of approximately 187 km2 . According to the results on the maps, the basin has an average land area of 12.5 km2 , which is suitable for new rural housing construction. Although each model has its advantages, the LR and FO methods produced more suitable results than the AHP method.

Thinning the active layer’s thickness of the semiconductor down to a level comparable with the carriers’ diffusion length while keeping its absorption high is an ultimate goal to boost the performance of optoelectronic devices. Strong interference in multilayer structures is one of the promising and practical solutions owing to their simple and large-scale compatible fabrication route. These nanocavity designs not only provide near unity absorption, but they can also be designed in a way that a spectrally selective absorption response can be achieved. In this letter, we will demonstrate the functionality of a metal–insulator–semiconductor (MIS) cavity to obtain spectrally selective ultrathin photodetectors. To prove our theoretical and numerical findings, a 4-nm-thick amorphous silicon (a-Si)-based MIS cavity is designed, fabricated, and characterized. The experimental results show that the optimized cavity design can act as an efficient visible blind ultraviolet (UV) photodetector. The proposed design shows the responsivity values of 120 and 2.5 mA/W in the UV ( $\lambda =\textsf {350}$ nm) and visible ( $\lambda =\textsf {500}$ nm) regions, respectively.

Ahmet Toprak and Ahmet Toprak
- Abstract
Erzählt wird die Geschichte des sozialen Aufstiegs eines türkischen'Gastarbeiterkindes', dessen Eltern Ende der sechziger Jahre nach Deutschland kamen. Mal nüchtern, mal humorvoll beschreibt Ahmet Toprak seinen Weg vom Hauptschüler in Köln zum Professor an der Fachhochschule in Dortmund. Dieser Weg verläuft alles andere als geradlinig und wie viele Menschen mit Einwanderungsgeschichte erfährt er interkulturelle Missverständnisse, Diskriminierung, aber auch unerwartete Ermutigung. Oftmals von seinem Umfeld unterschätzt, wird Toprak am Ende vom eigenen Erfolg am meisten überrascht. Seine Biographie belegt eindrucksvoll, wie wichtig eine gute Schulbildung sowie Unterstützung in der Familie für den Integrationserfolg sind.

MicroRNAs (miRNA) are a type of non-coding RNA molecules that are effective on the formation and the progression of many different diseases. Various researches have reported that miRNAs play a major role in the prevention, diagnosis, and treatment of complex human diseases. In recent years, researchers have made a tremendous effort to find the potential relationships between miRNAs and diseases. Since the experimental techniques used to find that new miRNA-disease relationships are time-consuming and expensive, many computational techniques have been developed. In this study, Weighted [Formula: see text]-Nearest Known Neighbors and Network Consistency Projection techniques were suggested to predict new miRNA-disease relationships using various types of knowledge such as known miRNA-disease relationships, functional similarity of miRNA, and disease semantic similarity. An average AUC of 0.9037 and 0.9168 were calculated in our method by 5-fold and leave-one-out cross validation, respectively. Case studies of breast, lung, and colon neoplasms were applied to prove the performance of our proposed technique, and the results confirmed the predictive reliability of this method. Therefore, reported experimental results have shown that our proposed method can be used as a reliable computational model to reveal potential relationships between miRNAs and diseases.

28. Soziologie: Gewalt als Inszenierungs- und Konstruktionsmotiv bei Jugendlichen

Ahmet Toprak and André Biakowski
- Abstract
Einschlagige Untersuchungen belegen, dass Jugendliche, die Gewalt anwenden, haufig selbst Opfer von Gewalt geworden sind (Kriminologische Forschungsinstitut Niedersachsen 2017). Seit November 2000 ist das „Recht auf gewaltfreie Erziehung“ in Kraft. Kinder haben das Recht, ohne korperliche, seelische oder sonstige Gewalt aufzuwachsen (§ 1631 II BGB). Das am 01.01.2002 in Kraft getretene Gewaltschutzgesetz schafft eine klare Rechtsgrundlage: „Wer schlagt, muss gehen“. Viele Jugendliche definieren sich nicht mehr uber eine erfolgreiche Schul- und Berufsausbildung, sondern legen Wert auf ein ausgepragtes Mannerbild, das stark von religiosen Vorstellungen gepragt ist. Das Bild des Mannes wird gepragt von seiner Fahigkeit zu entscheiden. In dieser Dynamik liegt der Begriff der Dominanz sowie der Verteidigung gegenuber Provokationen („angemacht werden“) inne.

Mit unserem Fazit mochten wir auch gleichzeitig padagogische Handlungsempfehlungen fur Politik und Zivilgesellschaft sowie einen Ausblick formulieren. Denn der Einfluss, den der religiose Radikalisierungsprozess und die damit verbundenen Ereignisse und Debatten auf das gesellschaftliche Miteinander haben, bringt die Frage nach politischen und zivilgesellschaftlichen Folgen mit sich. Die meisten medialen und gesellschaftlichen Diskurse fokussieren bei ihrer Auseinandersetzung mit dem Thema Radikalisierung sicherheitspolitische Aspekte.

11th International Conference on Electrical and Electronics Engineering (ELECO) -- NOV 28-30, 2019 -- Bursa, TURKEY WOS: 000552654100184 The aim of this study is to enhance the quality of automatic created dictionary. As far as we know, PMI (Pointwise Mutual Information) is the first time applied in order to determine representative words in the literature. A previously developed system is revised to experiment PMI effect on the selection of representative words additionally. Firstly, the meaningful words of the seed document/s arc determined by Helmholtz Principle. Then, PMI value is calculated for each of the meaningful words. Meaningful words are sorted by using the total PMI value in decreasing order. Finally, the top n meaningful words are added to the dictionary, where n is experimentally worked. Hash similarity is used to measure the performance of the dictionary. PMI enhances the dictionary quality for all n value. The dictionary hash similarity increases from 40.46% up to 68.75% for the best n value in the experiments.

Studies in the area of language lexicography are focused on automatic dictionary creation. In this article, an English document is given as an initial reference. In the study, meaningful words representing the reference document were identified. For this purpose, the Helmholtz Principle has been applied. The first dictionary words consist of the meaningful words of the reference document we call this seed. Then, with a loop, Web search is performed in the Azure Web Cognitive Web Search system using meaningful words from the most recently processed document. The first document from the search result has meaningful words with the Helmholtz Principle as applied to the reference document. The meaningful words found during the cycle are not added directly to the dictionary this time, and using the WordNet dictionary to avoid deviations, the similarity of each meaningful word with the dictionary formed is calculated. The meaningful words with similarity values higher than a certain threshold value are added to the dictionary and the search cycle is repeated using these words, and finally, when the desired number of words for the dictionary is reached, ends. In order to measure the performance of the dictionary, WordNet similarity calculation was used.

Date of Conference: 11-15 August 2019 Conference Name: SPIE Nanoscience + Engineering, 2019 Optical Solar Reflectors (OSRs) form the physical interface between the spacecraft and space and they are essential for the stabilization and uniform distribution of temperature throughout the spacecraft. OSRs need to possess a spectrally selective response of broadband and perfect electromagnetic wave absorption in the thermal-infrared spectral range, while strongly reflecting the solar energy input. In this work, we experimentally show that disordered and densely packed ITO nanorod forests can be used as an excellent top-layer metasurface in a metal-insulator-oxide cavity configuration, and a thermal-emissivity of 0.97 is experimentally realized in the spectral range from 2.5 to 25 μm. The low-loss dielectric response of ITO in the solar spectrum, from 300 nm to 2.5 μm range limited the solar absorptivity to an experimental value of 0.167. These make our proposed design highly promising for its application in space missions due to combining high throughput, robustness, low cost with ultra-high performance.

Precise control and stabilization of the operating temperature environment of spacecraft and satellites during their life cycle is of paramount importance to increase device reliabilities and reduce the thermomechanical constraints. Optical solar reflectors are the physical interface between the spacecraft and space, and they are broadband mirrors for the solar spectrum, while having strong thermal emission in the mid-infrared part of the electromagnetic spectrum. Strong light matter interactions in metamaterials and metasurfaces offer significant advantages compared to the conventional methods in performance, weight, launch, and assembly costs. However, the fabrication complexity of these metastructures due to necessitating lithography hinders their upscaling, reproducibility, large-area compatibility, and mass production. In this regard, we propose a facile, lithography-free fabrication route, exploiting oblique deposition to design a metasurface based on disordered and densely packed Indium Tin Oxide (ITO) nanorod forests. The excellent light trapping capability of the nanorod forests, randomness in the geometrical dimensions of these nanorods, combined with the lossy plasmonic nature of ITO in the thermal-infrared range led to strong coupling of thermal radiation to broad plasmonic resonances and, consequently, an experimental emissivity of 0.968, in a very wide range from 2.5 to 25 pm. In the solar spectrum, the low-loss dielectric characteristic of ITO resulted in an experimental solar absorptivity as small as 0.168. Our proposed design with high throughput, robustness, low cost, and high performance, therefore, shows great promise not only for space missions, but also for promoting environmentally friendly passive radiative cooling for our planet and thermal imaging in the field of security labeling.

International Congress on Semiconductor Materials and Devices (ICSMD) -- AUG 17-19, 2017 -- Selcuk Univ, Konya, TURKEY, WOS: 000495858400027, In this study, n-ZnO/p-Si heterojunction was produced by growing polycrystalline Zinc Oxide (ZnO) thin films on p-type Si (100) substrate at 500 mu m thickness using Pulsed Laser Deposition (PLD) method. The crystalline and morphologic structure of ZnO thin film were analysed by X-ray diffraction (XRD) and Atomic Force Microscopy (AFM) techniques. The photovoltaic (PV) property of n-ZnO/p-Si heterojunction was investigated by using current-voltage (J-V) measurement under illumination at 70 mW/cm(2). The silver (Ag) metal thin film was deposited by PLD to make ohmic contacts to the n-ZnO/p-Si heterojunction structure. The barrier height and the ideality factor were calculated to be 0.51 eV and 12.37, respectively, at room temperature (RT). The largest values of open circuit voltage (V-oc) and short circuit current density (J(sc)) were about 250 mV and 1.63 mA/cm(2), respectively. The photoelectric conversion efficiency in the range of 0.12% have been achieved and presented in this paper. (C) 2019 Elsevier Ltd.

Colorimetric detection of target molecules with insensitivity to incident-light polarization has attracted considerable attention in recent years. This resulted from the ability to provide rapid output and reduced assay times as a result of color changes upon altering the environment that are easily distinguishable by the naked eye. In this paper, we propose a highly sensitive refractive-index sensor, utilizing the excitation of guided modes of a novel two-dimensional periodically modulated dielectric grating-waveguide structure. The optimized nanosensor can numerically excite guided-mode resonances with an ultranarrow linewidth (full width at half-maximum) of 0.58 nm. Sensitivity is numerically investigated by considering the deposition of dielectric layers on the structure. For a layer thickness of 30 nm, the maximum sensitivity reached as high as 110 nm/refractive index unit (RIU), resulting in a very high figure of merit of 190. The fabricated devices with 30 nm aluminum oxide and zinc oxide coatings achieved a maximum sensitivity of 235.2 nm/RIU with a linewidth of 19 nm. Colorimetric detection with polarization insensitivity is confirmed practically by a simple optical microscope. Samples with different coatings have been observed to have clearly distinct colors, while the color of each sample is nearly identical upon azimuthal rotation. Excellent agreement is obtained between the numerical and experimental results regarding the spectral position of the resonances and sensitivity. The proposed device is, therefore, highly promising in efficient, highly sensitive, almost lossless, and compact molecular diagnostics in the field of biomedicine with personalized, label-free, early point-of-care diagnosis and field analysis, drug detection, and environmental monitoring.

Ahmet Toprak and Ahmet Toprak
- Abstract
Jungen aus türkischen und arabischen Familien brechen öfter die Schule ab, werden häufiger arbeitslos und gewalttätig. Zudem sind sie oft anfällig für religiöse oder nationalistische Radikalisierung. Ist das alles mit dem Bildungsniveau der Eltern und gesellschaftlicher Ausgrenzung zu erklären? Dem Erziehungswissenschaftler Ahmet Toprak zufolge gründet das Problem der neuen Bildungsverlierer nicht nur in einer verfehlten Integrationspolitik. Ausgehend von seiner Forschung, seinen Erfahrungen als Sozialarbeiter und seiner eigenen Biographie belegt er, dass der gesellschaftliche Misserfolg der Jungen in erster Linie an der Erziehung im Elternhaus liegt. Analytisch stark und unterstützt mit Fallbeispielen zeigt Toprak die Gründe und macht unmissverständlich klar, was sich ändern muss, damit Integration funktionieren kann.Ahmet Toprak, geboren 1970, kam mit zehn Jahren aus einem zentralanatolischen Dorf zu seinen Eltern nach Deutschland. Nach dem Hauptschulabschluss ging er zurück in die Türkei, machte Abitur und studierte ein Jahr lang Anglistik. 1991 setzte er sein Studium in Deutschland fort und wechselte schließlich zur Pädagogik. Nach dem Diplom 1997 arbeitete er als Anti-Gewalt-Trainer mit mehrfach straffälligen Jugendlichen mit Migrationshintergrund und promovierte parallel. Seit 2007 ist er Professor für Erziehungswissenschaft an der FH Dortmund.

MicroRNAs (miRNA) are a type of non-coding RNA molecules that are effective on the formation and the progression of many different diseases. Various researches have reported that miRNAs play a major role in the prevention, diagnosis, and treatment of complex human diseases. In recent years, researchers have made a tremendous effort to find the potential relationships between miRNAs and diseases. Since the experimental techniques used to find that new miRNA-disease relationships are time-consuming and expensive, many computational techniques have been developed. In this study, Weighted [Formula: see text]-Nearest Known Neighbors and Network Consistency Projection techniques were suggested to predict new miRNA-disease relationships using various types of knowledge such as known miRNA-disease relationships, functional similarity of miRNA, and disease semantic similarity. An average AUC of 0.9037 and 0.9168 were calculated in our method by 5-fold and leave-one-out cross validation, respectively. Case studies of breast, lung, and colon neoplasms were applied to prove the performance of our proposed technique, and the results confirmed the predictive reliability of this method. Therefore, reported experimental results have shown that our proposed method can be used as a reliable computational model to reveal potential relationships between miRNAs and diseases.

- Abstract
Der Anteil jugendlicher Gefangener mit Migrationshintergrund ist fast dreimal so hoch wie ihr Bevolkerungsanteil, was in besonderer Weise fur mannliche Jugendliche gilt, die aus arabischen Landern und der Turkei stammen. Auffallig dabei ist, dass sich ein hoher Anteil der Straftaten auf Gewaltdelikte erstreckt. Dabei haben viele Gewalttaten den Charakter eines klassischen Duells, d. h. es musste geklart werden, wer „im Recht“ ist. Genau diese gewalttatigen Austragungen werden zum uberwiegenden Teil polizeilich nicht erfasst, da sich beide Seiten zu diesem „Kampf “ bereiterklart haben und somit offentliche Stellen in der Regel nicht informiert werden. In diesem Beitrag werden, ausgehend von den Sozialisationsbedingungen mannlicher Kinder und Jugendlicher, Ursachen fur eine allgemeine Gewaltneigung rekonstruiert. Daraufhin werden Formen und Ausloser von (kollektiven) Duellen erlautert, um dann Schlussfolgerungen fur die Soziale Arbeit zu ziehen.
