ABSTRACT. Cyanobacterial biodiversity from different freshwater ponds of Thanjavur, Tamilnadu(India). Studies on the cyanobacterial biodiversity of 5 different freshwater ponds in and aroundThanjavur, Tamilnadu during summer month (June, 2004) has been made and compared their variationsamong five different ponds. In addition, certain physico-chemical parameters of pond waters such asdissolved oxygen, net productivity, pH, carbonate, bicarbonate, nitrate, nitrite, total phosphorus,inorganic phosphorus etc. were also analyzed and statistically compared with the cyanobacterialdiversity. Totally 39 species of 20 genera of cyanobacteria were recorded in all 5 different ponds.Only 6 species of cyanobacteria were identified in Pond 1 (Dabeerkulam), where a massive bloom ofMicrocystis aeruginosa was recorded, which had a significant effect in reducing the othercyanobacterial population. As many as five species namely Aphanothece microscopica, Synechocystisaquatilis, Merismopedia glauca, Oscillatoria limnetica and O. subbrevis were common in all theponds surveyed except in Pond 1.Key words. Biodiversity, ecosystem, cyanobacteria, Oscillatoria, Microcystis.RESUMEN. Biodiversidad de cianobacterias en diferentes charcas de agua dulce de Thanjavur,Tamilnadu (India). Se ha inventariado, y comparado entre sí, la biodiversidad de cianobacterias de 5charcas de agua dulce de Thanjavur, Tamilnadu (India); el estudio se llevó a cabo en junio de 2004.En paralelo, también se determinaron los valores de ciertos parámetros físico-químicos que podríanexplicar las variaciones en los valores de biodiversidad: oxígeno disuelto, productividad neta, pH,carbonato, bicarbonato, nitrato, nitrito, fósforo total, fósforo inorgánico, etc. Un total de 39 especiesde 20 géneros de cianobacterias se identificaron entre las 5 charcas. En la charca 1 (Dabeerkulam) sedetectaron 6 especies, pero cuando tuvo lugar una flor de agua de Microcystis aeruginosa las restantesespecies apenas se pudieron detectar.

Published: March 2020

ABSTRACT. Biodiversity of cyanobacteria in industrial effluents. In order to study the biodiversity of cyanobacteria in industrial effluents, four different effluents such as dye, paper mill, pharmaceutical and sugar were selected. The physicochemical characteristics of all the effluents studied were more or less similar. Totally 59 species of cyanobacteria distributed in four different effluents were recorded. Among the effluents, sugar mill recorded the maximum number of species (55) followed by dye (54), paper mill (45) and pharmaceutical (30). Except pharmaceutical effluent, others recorded heterocystous cyanobacteria. In total 26 species of cyanobacteria were recorded in common to all the effluents analysed. Of them, Oscillatoria with 13 species was the dominant genus which was followed by Phormidium (8), Lyngbya (2), Microcystis (2) and Synechococcus with single species. The abundance of cyanobacteria in these effluents was due to favourable contents of oxidizable organic matter, rich calcium and abundant nutrients such as nitrates and phosphates with less dissolved oxygen. Indicator species from each effluent and their immense value for the future pollution abatement programmes have also been discussed.Key words. Cyanobacteria, Industrial effluents.RESUMEN. Biodiversidad de cianobacterias en vertidos industriales. Se ha estudiado la biodiversidad de cianobacterias presente en vertidos industriales de diferente naturaleza (colorantes, fabricación de papel, sector farmacéutico y azúcar). Las características físico-químicas de los vertidos fueron más o menos similares. Se han identificado un total de 59 especies de cianobacterias en los cuatro tipos de vertidos. La mayor riqueza específica se encontró en el vertido de la industria azucarera (55 especies), seguida luego por la industria de colorantes, papel y productos farmacéuticos (54, 45 y 30 especies, respectivamente). Con la excepción del vertido de la industria farmacéutica, en los restantes vertidos se detectaron cianobacterias heterocistadas. El número de especies comunes a los cuatro vertidos ascendió a 26. Entre éstas, Oscillatoria, con 13 especies, fue el género dominante, seguido por Phormidium (8), Lyngbya y Microcystis (ambas con 2) y Synechococcus (1). La abundancia de cianobacterias en estos vertidos se debió al contenido en materia orgánica oxidable, altos niveles de calcio y nutrientes inorgánicos (nitratos y fosfatos) y bajos niveles de oxígeno disuelto. Se discuten el valor del indicador de especies de cada vertido y su importancia para los programas de reducción de la contaminación.Palabras clave. Cianobacterias, vertidos industriales.

Durch Nationalerziehung zu Demokratie und Frieden - Giuseppe Mazzini: Eine europäische Stimme aus dem 19. Jahrhundert
Authors: Buchmüller-Codoni Catherine
Published: March 2020

Giuseppe Mazzini ist vor allem bekannt als "Täter" des 19. Jahrhunderts. Doch auch als Denker nahm er massgeblich Einfluss: In seinen Texten analysiert er die Entwicklungen seiner Zeit und setzt sich in Briefen mit den prominenten Denkern der internationalen politischen Szene auseinander. Selbst mit dem Ziel eines republikanischen italienischen Nationalstaates angetreten, denkt er die Nation als Teil einer Nationengemeinschaft, den Menschen als Teil der Menschheit. Die Lektüre seines Werkes zeigt, wie innovativ seine Ansätze etwa zur Gleichstellung der Geschlechter oder zur internationalen Kooperation sind. Sich mit Mazzini als Denker auseinanderzusetzen, verhilft nicht nur zu einem besseren Verständnis der politischen Ideen des 19. Jahrhunderts. Seine Analysen sind auch im Hinblick auf heutige Debatten höchst aktuell.
Transient ischemic attack and ischemic upper limb in a case of subclavian artery pseudoaneurysm due to complicated clavicular bone fracture, a rare encounter
Authors: Sim Benjamin Ng Han , Lingam Ganeshwara Durai Raja , Matthew Susan Wendy , Puvanarajah Santhi Datuk
Published: March 2020

Background:

Subclavian pseudoaneurysm is a rare sequalae of untreated ipsilateral clavicular bone fracture and may be complicated with distal embolization, causing an acute ischemia of ipsilateral upper limb.

Case Presentation:

We present a challenging case of subclavian pseudoaneurysm who was later discovered to have a previously missed clavicular bone fracture. The case was complicated with concurrent recurrent ischemic limb and transient ischemic attack of the brain.

Conclusion:

Although subclavian artery pseudoaneurysm as a cause for transient ischemic attack has not been described in literature, we believe that our case has highlighted the possibility of such association.
From containment and rollback to escalation: Turkey’s Kurdish issue under the AKP
Authors: Jongerden Joost
Published: March 2020

This article will argue that the meetings between Turkey and the Kurdistan Workers Party PKK between 2006-2015 were employed by the Turkish state to gain advantage in the conflict they were supposed to be aimed at resolving. This appraisal of the PKK-Turkey talks thus helps to explain the escalation in the summer of 2015 - as the result, that is, not of a failed process of negotiations but of a failed intelligence operation.
How to Subdue a Minority? Historiography in Iraq under the Ba’th as a Political Means
Authors: Ahmed Kozad M.
Published: March 2020

History has been for long misused as a means of warfare by totalitarian, despotic and chauvi­nist regimes to demoralize the minorities. The relations between the cohabitants under such regimes usually become vassaldom of minorities to the ruling groups. Such a relationship forms a threat to the existence of both the minorities on one hand, and of the structure of the state and its institutions on the other, as happened in Iraq under Ba’th. In this piece it will be explained that a future constructive coexistence of ancient cohabitants in the Middle East like Kurds and Arabs is still burdened by a distorted history of the Kurds which Arab regimes have developed over decades and even centuries. It needs to be corrected mutually recognising their own independent ethnical, cultural and linguistic identity as well as separate historical roots in order to promote their future sustainable coexistence and cooperation.

Introduction to the Universal Declaration of Human Rights
Authors: Cataldi Giuseppe
Published: March 2020

The debate on the existence of universal human rights is always alive and involves not only the international law regime but also the enforcement of national laws as well as the relationship between cultural diversity and protection of human rights. It is a fact that not all the principles on human rights included in the major conventions and international acts on human rights come under the same regime, and so the idea of a distinction between conditional human rights rules and absolute human rights rules is not alien to the international mechanism sal, and for this reason its affirmation depends on the degree of acceptance of its principles. This acceptance has so far been much wider than one could imagine. Although it originally represented the point of view mainly of Western countries, the Universal Declaration has been successful as it immediately sought to give precise content to the commitments solemnly made by State with the approval of the United Nations Charter.
Solidarity and Social Justice in the European Union Seventy Years after the Universal Declaration of Human Rights: The Role of European Judges
Authors: Zammartino Francesco
Published: March 2020

Seventy Years after its proclamation, the Universal Declaration of Human Rights, despite not having a binding force for the states, still provides at international level the fundamental text from which the principles and the values for the preservation of liberty and right of people are taken. In this article, the author particularly underlines the importance of Declaration’s article 1, which states: “All human beings are born free and equal in dignity and rights”. With these words the Declaration presses states to undertake economic policies aimed at achieving economic and social progress for all individuals. Unfortunately, we also have to underline the lack of effective social policies in government programs of the E.U. Member States. The author inquires whether it is left to European judges to affirm the importance of social welfare.
The Human Right to Water from the Universal Declaration of Human Rights to the New Agenda for Sustainable Development
Authors: Pace Marianna
Published: March 2020

The article explores the evolutionary path that led to the emergence of the right to water as human rights, since the Universal Declaration of Human Rights till to its inclusion in the 2030 Agenda for Sustainable Development. In particular, on the one hand the paper analyses the definition and the content of the right to water, as well as the obligations stemming for contracting States to the international treaties recognizing this right. On the other one, it focuses specifically on how to ensure an effective guarantee of the right to water. Finally, the analysis assesses the contribution of Goal 6, included in 2030 Agenda for Sustainable Development, to the international water law regime.
Tourism as a Tool for the Fulfilment of the Rights to Rest and Leisure Enshrined in Article No. 24 of the Universal Declaration of Human Rights
Authors: Romano Bianca Nicla
Published: March 2020

Art. 24 of the 1948 Declaration of Human Rights recognises and protects the right of the individual to rest and leisure. This right has to be fully exercised without negative consequences on the right to work and the remuneration. Tourism can be considered one of the best ways of rest and leisure because it allows to enrich the personality of the individual. Even after the reform of the Title V this area is no longer covered by the Italian Constitution, the Italian legal system protects and guarantees it as a real right, so as to get to recognize its existence and the consequent compensation of the so-called “ruined holiday damage”. This kind of damage has not a patrimonial nature, but a moral one, and the Tourist-Traveler can claim for it when he has not been able to fully enjoy his holiday - the essential fulcrum of tourism - intended as an opportunity for leisure and/or rest, essential rights of the individual.

The Role of Technology in High-tech Agricultural Development in the Context of Social, Ecological and Economic Transformation in Vietnam
Authors: Ngoc Anh Nguyen Thi
Published: March 2020

The world has come to the point that requires more agricultural production using less resource. Moreover, the previous important elements for agricultural growth such as water, land, and human resources no longer play the decisive roles in the agricultural development. Instead, the application of high technology is the “key solution” for countries that depend on the agricultural economy like Vietnam. In Vietnam, agriculture is a particular economic sector that uses the majority of natural and human resources of the country. In the context of the social, ecological and economic transformation, the development of high-tech agriculture is not only about economic efficiency but also the issues of sustainable environmental development. High technology will be the solution to this multi-objective problem. The paper focuses on assessing the necessity of high-tech agricultural development and analyzing the role of technology in high-tech agricultural development, especially in the context that contains many challenges and opportunities.

El ensayo hace énfasis no solo en las características personales del profesor, sino también en su concepción del trabajo del sociólogo y de la sociología como disciplina cuyo carácter crítico proviene precisamente de su dimensión empírica como "artesa­nía intelectual”.
El nuevo trabajo industrial: una mirada crítica desde la calidad del empleo
Authors: Rodríguez Miglio Martín , Erbes Analía , Roitter Sonia , Pujol Andrea
Published: March 2020

En este trabajo se aborda la relación entre las nuevas formas de organización de la pro­ducción y la calidad del empleo, a partir de una revisión crítica de las perspectivas más tradicionales. En particular, se discute el impacto de la adopción de las nuevas formas de organización de la producción sobre la calidad del empleo. Para ello se analizan los cam­bios operados en el proceso de trabajo desde los inicios del capitalismo, especialmente los ocurridos en el último cuarto del siglo XX. Entre las principales conclusiones se desta­ca que los cambios producidos en los factores que configuran la organización productiva y la gestión del trabajo tienen un impacto discutible sobre la calidad del empleo y el bienestar de los trabajadores.
Los estudios demográficos a inicios del siglo XXI
Authors: Editorial Revista Sociedad y Economía Comité
Published: March 2020

En las últimas décadas las investigaciones sociodemográficas y, en general, los estudios de población han ampliado, diversificado y enriquecido sus enfo­ques a partir de la incorporación de la perspectiva de género, la inclusión de las dimensiones étnico-raciales, las consideraciones que marcan las diferencias etarias y el reconocimiento de la diversidad sexual, entre otros. Esta apertura del campo de la investigación sociodemográfica ha favorecido un mayor reconoci­miento de las desigualdades sociales y de la alteridad, y ha permitido instalar los estudios sociodemográficos en un terreno explicativo de primer orden.
La ampliación del campo sociodemográfico se ha expresado en un mayor fortalecimiento en la identificación de patrones y tendencias sociales y ha con­tribuido de manera significativa a la comprensión del cambio social en las so­ciedades contemporáneas. En virtud de la interesante dinámica que se expresa en este campo del conocimiento, la revista sociedad y economía presenta la edición de su número 29, con el tema central: Los estudios sociodemográficos a inicios del siglo XXI. Los ocho artículos seleccionados entre los que respondie­ron a la convocatoria constituyen una significativa muestra de la diversidad y complejidad que implica la incorporación de los emergentes enfoques analíti­cos, tanto en aquellos artículos que enfatizan en uno de estos enfoques como en aquellos que, de manera innovadora, avanzan en sus articulaciones y muestran sus intersecciones.

Los migrantes colombianos en la prensa colombiana: una lectura de género 1990–2006
Authors: Bazurto Botero Victoria Elena
Published: March 2020

Este artículo tiene como objetivo identificar las representaciones creadas a través del dis­curso de los periódicos El Tiempo y El Espectador, en torno a las emigrantes colombianas a España. Para tal fin, se analizaron los artículos de estos rotativos desde el 1 de enero de 1990 hasta el 31 de diciembre de 2006. A pesar de reconocer la importancia de las mujeres dentro del fenómeno migratorio colombiano, persiste un discurso no adaptado en los pe­riódicos en el que predomina el genérico masculino. Por otro lado, las representaciones culturales positivas que les son atribuidas resultan minoritarias, frente a aquellas que les designan como responsables de la desestructuración familiar y en tanto que víctimas de la trata y del tráfico de personas.

Ejes de infraestructura vial y dinámicas urbano-regionales. El caso del corredor Bogotá-Bucaramanga, Colombia (1950-2005)
Authors: Rincón Avellaneda María Patricia
Published: March 2020

La pregunta central del presente artículo gira en torno a cómo la planificación territorial y el diseño de infraestructuras de transporte influencian y generan condiciones de desequilibrioterritorial. Para resolverla, se presenta el estudio de caso del eje vial que une las ciudades de Bogotá D.C., capital de Colombia, y Bucaramanga, capital del departamento de Santander. A través de una serie de indicadores, se revisaron sus dinámicas con el fin de identificar los cambios producidos en el período 1950-2005, durante el cual se pasa de tener solo una vía de comunicación a tener tres. En ese lapso se encontraron señales claras de migración poblacional, decaimiento de la actividad económica, y de flujos de transporte en las poblaciones ubicadas a lo largo de la ruta más antigua, que entra en desuso al momento de aparecer la segunda opción.
Crecimiento municipal en Colombia: el papel de las externalidades espaciales, el capital humano y el capital físico
Authors: Galvis-Aponte Luis Armando , Hahn-De-Castro Lucas Wilfried
Published: March 2020

En el presente trabajo se realiza un análisis del crecimiento económico municipal enColombia, en el período 1993-2012. El objetivo es evaluar la existencia de convergenciateniendo en cuenta las externalidades del capital humano y el capital físico. Siguiendoel análisis propuesto por Mankiw, Romer y Weil (1992), se estiman las ecuaciones deconvergencia aumentadas con capital humano. Se sigue la propuesta de Ertur y Koch(2006, 2007), quienes incluyen las externalidades tecnológicas en el análisis del modeloque considera solamente el capital físico (Solow 1956), y en el modelo aumentado con elcapital humano. Los resultados indican que cuando no se tienen en cuenta los efectosde los spillovers, existe evidencia de convergencia. Esta, sin embargo, desaparece cuandodichos efectos son añadidos al modelo.
Dependencia y subdesarrollo en tiempos de globalización. Las experiencias neoliberales y neodesarrollistas en la Argentina
Authors: Wainer Andrés
Published: March 2020

Las transformaciones que ha sufrido la economía mundial a partir de la globalización obligan a repensar las relaciones de dependencia y el subdesarrollo. En este sentido, el artículo se propone analizar si durante las dos últimas experiencias políticas en la Argentina (el “neodesarrollismo” y el regreso del neoliberalismo) hubo cambios sustantivos en el carácter dependiente de su economía y en qué sentido operaron los mismos. Para ello se presentan algunas variables clave de la evolución de la economía argentina en las últimas décadas y se abordan cuestiones conceptuales como el destino del plusvalor y el papel que cumplen instrumentos centrales en un marco librecambista como el tipo de cambio. Se concluye que si bien las políticas neoliberales han profundizado la situación de dependencia, los gobiernos “neodesarrollistas” tampoco han logrado impulsar un proceso sostenido de desarrollo.

Detection of hydrogen peroxide (H2O2), which is responsible for numerous damages when overproduced, is crucial for a better understanding of H2O2-mediated signalling in physiological and pathological processes. For this purpose, various“off-on” small fluorescent probes relying on a boronate trigger have been developed. However, they suffer from low kinetics and do not allow forH2O2-detectionwith a short response time. Therefore, more reactive sensors are still awaited. To address this issue, we have successfully developed the first generation of borinic-based fluorescent probes containing a coumarin-scaffold. We determined the in vitrokinetic constants of the probe toward H2O2-promotedoxidation. We measured 1.9x104m-1.s-1as a second order rate constant, which is 10 000 faster than its boronic counterpart (1.8 m-1.s-1). This remarkable reactivity was also effective in a cellular context, rendering the borinic trigger an advantageous new tool for H2O2detection.

Chitosan được ứng dụng nhiều trong lĩnh vực y dược nhờ khả năng tương thích sinh học cao. Trong đó, vật liệu dạng hạt rỗng được quan tâm nghiên cứu nhờ hiệu suất hấp thụ thuốc cao và khả năng phóng thích thuốc ổn định trong thời gian dài. Các nghiên cứu trước đây cho thấy để tổng hợp hạt chitosan có cấu trúc rỗng người ta phải sử dụng dung môi hữu cơ và tác nhân tạo liên kết độc hại, làm ảnh hưởng đến tính an toàn sinh học của vật liệu. Vì vậy, mục tiêu của nghiên cứu này là chế tạo hạt chitosan với cấu trúc rỗng bằng phương pháp đơn giản và an toàn. Chitosan được tổng hợp từ chitin sau đó được đưa vào quá trình tạo hạt với tác nhân sodium tripolyphosphate (STPP). Kết quả cho thấy hạt với đường kính lỗ rỗng lớn nhất được tạo ra từ chitosan với khối lượng phân tử 205,6 kDa và nồng độ chitosan 2% (w/v) trong trong acetic acid 1% (v/v) tại pH = 9 của dung dịch STPP.

Food and Mood: Exploring the determinants of food choices and the effects of food consumption on mood among women in Inner London.
Authors: Leeds Joanna , Keith Regina , Woloshynowych Maria
Published: March 2020

Introduction: The aim of this study was to explore the relationship between food and mood against the backdrop of increased mental health and nutrition cognizance within public health and scientific discourses. Mood was defined as encompassing positive or negative affect.

Methodology: A constructionist qualitative approach underpinned this study. Convenience sampling in two faith-based settings was utilised for recruiting participants, who were aged 19-80 (median,48) years. In total 22 Christian women were included in the research, eighteen were in focus groups and four were in individual semi structured interviews. All were church-attending women in inner London. A thematic analysis was carried out, resulting in four central themes relating to food choice and food-induced mood states.

Findings: Women identified a number of internal and external factors as influencing their food choices and the effect of food intake on their moods. Food choice was influenced by mood; mood was influenced by food choice. Low mood was associated with unhealthy food consumption, apparent addiction to certain foods and overeating. Improved mood was associated with more healthy eating and eating in social and familial settings.

Discussion: Findings indicate food and mood are interconnected through a complex web of factors, as women respond to individual, environmental, cultural and social cues. Targeting socio-cultural and environmental influences and developing supportive public health services, via faith-based or community-based institutions could help to support more women in their struggle to manage the food and mood continuum. Successful implementation of health policies that recognise the psychological and social determinants of food choice and the effect of food consumption on mood, is essential, as is as more research into life-cycle causal factors linking food choice to mood.

Published: March 2020

The study was carried out to obtain angiotensin converting enzyme (ACE) with high
specific activity and to evaluate the ability to maintain enzyme activity in extract products
as well as in rabbit lungs using frozen condition. In the scope of the content, the study
conducted an evaluation to select the appropriate extraction solvent of four solvents
including acetone, ethanol, Tris-HCl and distilled water. Initially, the research results have
helped determine distilled water as the suitable extraction solvent and the difference is not
statistically significant compared to Tris-HCl solvent. Angiotensin converting enzyme
extract that was obtained by distilled water solvent has a specific activity of 10.35 U/g
protein. In addition, the study investigated the ability to maintain angiotensin converting
enzyme activity in rabbit lung and crude enzyme product during frozen storage (-18±2°C).
The results of the study showed that angiotensin converting enzyme activity could be
maintained for 3 months in rabbit lungs and 4 months in the crude product. Besides, the
study also used ammonium sulfate with different concentrations to conduct angiotensin
converting enzyme collection from extract product. The results of this content help
determine the use of saturated ammonium sulfate with concentrations of 50% to 60% for
the highest efficiency. The precipitation process helped obtain ACE products with a purity
of 4.22 times, the specific activity of 42.64 U/g protein and the recovery rate of ACE up to
29.37%.

İngiliz Klasik İktisat Okulu Adam Smith tarafından 1776 yılında kurulmuştur. Alman Tarihçi Okulu daha çok İngiliz Klasik İktisat Okuluna eleştiriler yapan Kıta Avrupasına ait bir okul olarak tanınmıştır. Tarihçi Okula göre Kıta Avrupası
için tamamen farklı ve daha kapsamlı bir ekonomik sistem gereklidir. Tarihçi Okul üyeleri bireyin ancak sosyal ilişkiler ağı içinde var olabileceğini düşünmüştür. Bu bakımdan bireyi toplumdan soyutlayan, bireyin bencilliğini iktisadi
analizin merkezine oturtan Klasik ve Neoklasik İktisat Okullarına karşı çıkmışlardır. Tarihçi Okul bencilliğe ve egoizme dayalı bir refahın mümkün olmadığını savunmuştur. 19. yüzyılın sonlarında Alman Tarihçi Okulunun köklerinden
iktisat sosyolojisi adlı alt disiplin doğmuştur. Neoklasik teoriyi yetersiz bulanlar bu alanda çalışmalar yapmıştır. Türkiye’de iktisat sosyolojisi alanında çalışmalar yapmış önemli isimler arasında Ziya Gökalp, Sabri Ülgener,
Ahmet Güner Sayar ve Cahit Talas bulunur. Bu çalışmada, Türk toplumu perspektifinden Alman Tarihçi Okulu ile iktisat sosyolojisi arasındaki ilişki kısaca anlatılmaktadır. Ayrıca, çalışmada Türkiye’nin tıpkı Kıta Avrupası ülkeleri
gibi 3. Yol ülkesi olduğu ileri sürülmektedir.

İşe geliş gidiş hareketi kırsal ve şehirsel alanlar arasında bütün ülkelerde ortaya çıkan bir durumdur. İnsanlar çeşitli nedenlerle ikamet ettikleri bölge ile çalıştıkları bölge arasında bazen uzun sayılabilecek yol gitmek zorunda kalmaktadır. Literatüre işe geliş gidiş (commuting) olarak geçen bu durum dünya genelinde önemli bir ekonomik değere ulaşmıştır. Bu nedenle işe geliş gidişin yerleşim alanları ve bireyler üzerindeki etkilerini önlemeye yönelik alınabilecek çeşitli tedbirler tartışılmaya başlanmıştır. Yapılan çalışmalarda işe geliş gidişin boyutu, özellikle çalışanların maddi durumuna ve bölgeler arasındaki ekonomik, sosyal ve çevresel faktörlerde ortaya çıkan farklılıklara göre değiştiği değerlendirilmiştir. Bu çalışmada Eskişehir’de ikamet edip Kütahya’ya iş için geliş gidiş davranışlarının sürdürülebilir şehir kavramı çerçevesinde açıklanması amaçlanmıştır. Buna yönelik yapılan anket çalışmasında sürdürülebilir şehir kavramının ölçüm kriterleri dikkate alınmış olup sonuçlar bu çerçevede değerlendirilmiştir. Analizler sonucunda elde edilen bulgularda ise Eskişehir’den Kütahya’ya işe geliş gidiş yapan bireylerin davranışlarının özellikle çevresel, sosyal ve bir ölçüde de ailevi nedenlere dayandığı, ekonomik nedenlerin önem derecesinin ise düşük olduğu belirlenmiştir.

Osmanlı’nın son dönemi ile Cumhuriyet yıllarına tanıklık eden yazar, Türk toplumunun değişim öykülerini romanlarının ana konusu yapar. Tanzimat sonrası Batı kültürü ile tanışan Türk halkı, Cumhuriyet’e kadar ve sonrasında bu kültürün etkilerine maruz kalır. Edebi eserlere konu olan olumsuz etkilerden biri şüphesiz yanlış batılılaşmadır. Özellikle romanlara, karakterlerin toplumsal ve bireysel yabancılaşması olarak dahil edilen bu izlek, Yakup Kadri’nin de ele aldığı olgulardan biri olur. Yaban’da, Birinci Dünya Savaşı yenilgisine tanıklık eden ve bu yenilgiden sağ kolu kesilerek çıkan şehirli Türk aydınının Anadolu’da bulunduğu süreçte yaşadığı çıkmazlar dile getirilir. Romanda, aydın-köylü çatışmasına evrilerek başkişi Ahmet Celâl’in, “yaban”lığına değin vardırılan sorunlar yumağı, farklı ideallerin yansımasını içerir. Çalışmada, köy halkının, bir savaş kahramanı ve Türk aydını olan Ahmet Celâl’in toplumsal kimliğine yapıştırdığı/ yakıştırdığı yaban’lığı değerlendirilecek ve bu yaban’lığın; kendine ve başkalarına/ çevresine yabancılaşma şeklinde tinsel kimliğe sinen belirtileri irdelenecektir.
