Authors: Aldardeer Ahmed Abdel Kahaar , El-Badry Ashraf Mohammad
Published: July 2021

Background: With the current high incidence of hepatocellular carcinoma (HCC), more patients even with large and huge HCC are considered for liver resection.Methods: Medical records of consecutive adult cirrhotic patients who underwent partial hepatectomy for huge HCC (≥10 cm, huge HCC group) versus small HCC (<5 cm, small HCC group) at Sohag university hospital (January 2016 to December 2020) were analyzed. Both groups were compared regarding postoperative morbidity and risk of mortality following post hepatectomy liver failure (PHLF) as defined by the 50-50 criteria (50% mortality occurs among patients who developed increased plasma bilirubin >50 μml/l and reduced prothrombin activity <50% on postoperative day 5 (POD-5).Results: Thirty two patients were enrolled (16 per group), with median age of 56 (range 38-81) years, 22 were males. In correlation with resection of more liver segments in the huge HCC group, post hepatectomy alteration of liver functions (bilirubin rise and reduction of albumin and prothrombin concentration) was significantly pronounced among patients who had resection for huge compared with small HCC (p<0.05). Huge HCC group exhibited significantly worse postoperative complication score (p< 0.05) and needed significantly prologed periods of hospital stay (p<0.05). Concurrent persistence of PHLF and thrombocytopenia until POD-5 occurred in 3 patients (2 with huge HCC and 1 with small HCC). Among those patients, only one from huge HCC group died (mortality 6%) postoperatively.Conclusions: Liver resection provides safe and effective treatment strategy for carefully selected cirrhotic patients with huge HCC.

Authors: Shiri Mohammadabd Hamideh , Afshani Seyed Alireza
Published: July 2021

Introduction: Today, religious coping behaviors such as prayer, hope in God and participation in collective rituals are considered as one of the main determinants of health behaviors because it can have positive effects on women's behavioral strategies with the aim of self-care. However, there is little empirical research in this scope and the present study intends to investigate the relationship between religiosity and self-care of women.
Methods: The present research was a survey cross-sectional study. The population of this study included all 18-70 year old, of Yazd in 2020. The sample size was determined based on Cochran formula 737 and was used with Probability Proportionate to Size Sampling (PPS). Data based on a researcher-made self-care questionnaire and religiosity standard questionnaire were collected. Results were analyzed using the software SPSS and Amos 24.
Results: The results on the relationship between religiosity and self-care revealed that the effect of religiosity on self-care was positive and significant. The effectiveness rates of religiosity on women's self-care in the marginal, the middle, and the upper areas were 0.56, 0.38, and 0.36, respectively (p<0.001). Also, there was no significant difference between the intensity of the relationship between religiosity and self-care in the three areas (CR<1.96). Also, the structural equation model had a good fit.
Conclusions: It is necessary that since women's decision to adopt care-oriented behavior is conditioned by the social conditions that surround them, we should pay special attention to the social contexts in which they live to improve self-care performance in them.

Published: July 2021

Introduction: Ammonia in form of ammonium ions is toxic and could decrease the dissolved oxygen in water and endanger the aquatic life. The aim of this study is the removal of ammonium using oxidation and adsorption by catalytic ozonation and clinoptilolite zeolite, respectively.
Methods: The research method is Experimental. First, optimal pH of ammonium adsorption on carbon catalyst (5 g/L), Garmsar and Firoozkooh zeolites and oxidation were determine. Then, in catalytic ozonation process, the effect of other variables on ammonium removal efficiency such as the concentration of carbonic catalyst (0.5- 50 g/L) and the reaction time were investigated. Then the effect of retention time and adsorbent concentration on adsorption of the remaining ammonium and nitrate produced by the oxidation process using zeolites and their modifications were determined.
Resuts: The results showed that optimum pH for the ammonium adsorption process by carbon catalyst, catalytic ozonation and zeolite was 8, 9 and 8, respectively. However, the optimum pH 4 was determined for nitrate removal. The highest ammonium absorption capacity was related to natural Firoozookh zeolite and 18.5 mg/g, and the effect of ligand and acid modification decreased 12 and 14% of absorbed capacity, respectively. It is also, the highest nitrate removal efficiency was related to Garmsar ligand modified zeolite (98%) and an absorption capacity of 11.2 mg/g. In the COP/absorption process the concentration of ammonium was decreased to 0.6 m /L.
Conclusion: This method effectively eliminates ammonium, and the modification of zeolite with cationic surfactant increases the efficiency of nitrate removal and the concentrates of all pollutants are brought below standards.

Published: July 2021

Despite the development of hybrid and electric vehicles, a many-million population of cars with combustion engines, and particularly CI engines occurs on the roads. Also, many stationary CI engines are still utilized. Despite their improved technologies and characteristics the modern CI engines negatively affect an environment due to cold starting problems. Below 0 °C, engine starts are problematic due to the decreased battery performance and the spray characteristics, the increased ignition delay time, and the engine oil viscosity. Therefore, various glow plugs are applied to facilitate this process. Types, features, and applications of glow plugs in various engines have been discussed in the paper. One case of failure of glow plug has been presented in the article, including the cause of it.

Published: July 2021

One of the many important challenges of the modern world is the greenhouse effect of CO2. It is necessary to implement solutions that will eliminate it. Since the easiest way to eliminate the greenhouse effect is to reduce hydrocarbons fuel consumption, it is important to evaluate the fuel (energy) consumption in long term operation. The article presents a proposal for the use of the so-called vehicle energy footprint. The method of creating such a trace is presented and illustrated with specific results of data analyzes. The data is publicly available, which means that the presented method can be independently verified. It has also been shown that the use of the method not only organizes the analyzes, but also leads to information that cannot be obtained with other methods. It therefore seems that an attractive tool has been developed for future applications.

Published: July 2021

Geothermal development requires an understanding of changes in pore permeability caused by repeated thermal shock fatigue damage in hot dry rock. Research on the subject can aid the evaluation of the longevity and mining value of enhanced geothermal systems (EGS). However, few relevant studies are currently available. In this study, the change characteristics of pore permeability in granite following different heating–cooling cycle temperatures (250°C, 350°C, 450°C, 550°C, and 650°C) and numbers of cycles (1, 5, 10, 15, and 20 cycles) were analyzed. Results show that with increasing temperature, the uneven thermal expansion and thermal shock effect of minerals promote crack development, leading to increases in the porosity and permeability of granite, particularly at temperatures above 450°C. When the heat treatment temperature was below 450°C, the number of cycles only slightly affected the porosity and permeability; meanwhile, when the temperature exceeded 450°C, the porosity and permeability increased significantly with an increase in the number of cycles. Moreover, three-dimensional nonlinear fitted relationships among porosity (or permeability), cycle temperature, and number of cycles have been established for the first time with correlation coefficients (R2) above 0.9, which reveals the change rules of pore permeability after quenching in hot dry rock. The results can be used to evaluate the efficiency of geothermal reservoir energy extraction and aid in geothermal reservoir design.

This article reviews the relationship between the oil market and the stock market during the Corona outbreak. This study aims to analyze the stock market and the effect of oil prices on this market during the corona pandemic. The hypothesis of this paper is whether while oil prices shocks happen due to business cycle fluctuations and some other reasons like political reasons, occur; The correlations between changes in Brent oil prices and stock market indices tend to be affected by named corona indexes. Forecasting the stock market in each period has been difficult and the value of stock index has been affected by various factors. Among these factors has been the oil and gas sector, especially in countries dependent on the revenue from their sales. On the other hand, the outbreak of Covid-19 pandemic has led to profound changes in both areas. This study examines relationship between Brent oil price and Iran stock market Index during the outbreak of corona pandemic. Research method is, vector autoregression model (VAR) which using daily data covering the period from February 20, 2020 to August 21,2020. The findings of this study suggest that a negative causal effect from Brent oil price changes to the Iran stock market Index. Also, the results of impulse response functions and variance decompositions showed that some corona pandemic indicators have significant effects on the stock index.JEL Classification: I18, E44, Q4, C5

Authors: Wang Chao , Liu Xujin , Zhang Fan
Published: July 2021

BackgroundNecrotizing fasciitis(NF) is a severe progressive infectious disease where a synergistic action of multiple bacteria results in suppurative necrosis of the skin and soft tissue. Despite being a relatively uncommon infection, its mortality is significantly high. In this case report ,we describe the clinical presentation, management and outcome of a patient with NF of the left lower limb complicated with the abscess of retroperitoneal space and ensuing septic shock and dysfunction of heart and liver. Finally, we analyzed six cases we have treated before including this one and a retrospective study was performed.Case presentationA 69-year-old male patient, complaining about the pain of left lower limb and high fever due to uncertain reasons, featuring the tenderness of affected limb and left lower abdomen, was diagnosed with the NF complicated with the abscess of retroperitoneal space. The patient then develop septic shock and dysfunction of heart and liver. After repeated debridement of necrosis tissue, in combination with multiple antibiotics, laboratory test methods and the vacuum-assisted closure(VAC) therapy, the patient survived ,gradually improved and finally got a full recovery.MethodsA retrospective study was performed on six patients with NF of unilateral lower limb from March 2018 to October 2019. All patients were given systemic antibiotics and nutrition support. During the first stage, repeated surgical debridement with negative-pressure wound therapy(NPWT) was performed. Direct suture of the wound was performed in the second stage.ResultsThe incision healed well in all patients, and no infection or necrosis occurred in the wound. During the follow-up of 6.5 months (range, 5–9 months), no recurrence of infection or incision rupture occurred.DiscussionAlthough prompt diagnosis and adequate antibiotic therapy are basic for the treatment of patients with NF, early and repeated surgical intervention is vital for a favorable outcome. Thus, adjuvant treatment for NF such as negative pressure wound therapy (NPWT) using the VAC are very useful to accelerate wound healing.ConclusionsPrompt diagnosis, adequate antibiotic therapy and more crucially, early and repeated surgical debridement of the necrotic tissue combined with VAC therapy play a collaborative role in the successful treatment of NF.

Valve as an important part of the gas distribution mechanism, is an crucial part of the engine. When the engine works, the valve is subjected to high temperature, high impact, frictional wear and corrosion and other harsh working conditions, and the reliable and durable valve has an important impact on the safety and reliability of the engine. In this paper, a model of four-stroke marine diesel engine valve is used as the research object, and the intake valve set and exhaust valve set models are established respectively. Heat transfer simulation and failure analysis of inlet and exhaust valves of different structures and materials under different operating conditions were carried out using finite element analysis. The results show that the different valve structures and manufacturing materials have different effects on the reliability of the valves; Changing the valve structures and choosing different valve manufacturing materials have a greater impact on the heat transfer and deformation, thus affecting the overall reliability of the valves.
Oxidation state of iron and Fe-Mg partitioning between olivine and basaltic martian melts

Published: July 2021

We performed a series of experiments at 1 atm pressure and temperatures of 1300–1500 °C to determine the effect of oxygen fugacity on the oxidation state of Fe in a synthetic martian basalt. Ferricferrous ratios were determined on the quenched glasses using Mössbauer spectroscopy. Following the conventional doublet assignments in the spectrum, we obtain a Fe3+/ΣFe value of 0.19 at 1450 °C and an oxygen fugacity corresponding to the QFM buffer. If we apply the Berry et al. (2018) assignments the calculated Fe3+/ΣFe drops to 0.09, and the slope of log(XFeO1.5melt/XFeOmelt) vs. log(fO2) changes from 0.18 to 0.26.

Combining oxidation state data together with results of one additional olivine-bearing experiment to determine the appropriate value(s) for the olivine (Ol)-liquid (liq) exchange coefficient, KD,Fe2+-Mg = (FeO/MgO)Ol/(FeO/MgO)liq (by weight), suggests a KD,Fe2+-Mg of 0.388 ± 0.006 (uncertainty is one median absolute deviation) using the traditional interpretation of Mössbauer spectroscopy and a value of 0.345 ± 0.005 following the Mössbauer spectra approach of Berry et al.

We used our value of KD,Fe2+-Mg to test whether any of the olivine-bearing shergottites represent liquids. For each meteorite, we assumed a liquid composition equal to that of the bulk and then compared that liquid to the most Mg-rich olivine reported. Applying a KD,Fe2+-Mg of ~0.36 leads to the possibility that bulk Yamato 980459, NWA 5789, NWA 2990, Tissint, and EETA 79001 (lithology A) represent liquids.
20. YÜZYIL ÖNCESİ AMERİKAN PORTRECİLİĞİ HAKKINDA BİR DEĞERLENDİRME

Published: July 2021

Bu makalenin konusunu 20. yüzyıl öncesi Amerikan portreleri oluşturmaktadır. Öne çıkan portre ressamları ve bazı çalışmaları ile dönemler tanıtılmaya çalışılmıştır. Portre sanatı tanıtılırken tarihsel bağlamda Amerika kıtasında yaşanılan siyasi, sosyal, ekonomik, kültürel oluşum ve dönüşümler de incelenmiştir. Kolonileşme Dönemi ile Erken Cumhuriyet Dönemleri arasında, Amerikan portresi tarz ve konu bakımından değişmişti. 19. yüzyılın ilk dönemlerinde, kendine özgü millî bir Amerikan tarzı oluşmuştur. Portrelerde Amerika’ya Kolonileşme Dönemi’nde çeşitli ülkelerden ve çeşitli kültürlerden, çoğu yetersiz eğitimi olan pek çok ressam da gelmiş ve Amerikan sanatının gelişimine katkı sağlamışlardır. Kıtada yaşayan siyahi ve diğer yerli grupları da Amerika kıtasının potasında kendi kültürleriyle var olmuş ve özgün bir Amerikan sanatı oluşumuna destek vermişlerdir. Amerikan portre sanatı geniş bir üretim evresini kapsaması nedeniyle bütün Amerikalı ressamlara bu makalede yer vermek mümkün olmamıştır.

Published: July 2021

Bilgi ve iletişim teknolojilerindeki gelişim, modern çalışmanın bilindik mekân ve zaman sınırlarının dışına çıkmasını sağlayarak onun doğasını derinden etkilemiştir. Tele çalışma, bahsedilen gelişimin bir sonucu olarak ortaya çıkmış ve temelde bilgi ve iletişim teknolojilerinin sunduğu imkânların kullanılmasına dayalı esnek bir çalışma türüdür. Bu makalenin temel amacı; ev eksenli tele çalışmanın işçiler açısından ortaya çıkardığı sorunları, uygulama örneklerini dikkate alarak ortaya koymaya çalışmaktır. Buradan hareketle makalede tele çalışmanın gelişimi ve doğası anlatılmış, neoliberalizmin esneklik anlayışı ile tele çalışma arasındaki ilişki açıklanmış, ev eksenli tele çalışmanın işçiler açısından ortaya çıkardığı dezavantajlar, tele çalışmaya ilişkin farklı uygulamalar üzerinden tartışılarak sorunlu alanlar belirlenmeye çalışılmıştır. Sonuç olarak ev eksenli tele çalışmanın çalışanlar için çalışma sürelerinin ve iş yoğunluğunun artması, evin iş yerine dönüşmesi sebebiyle aile hayatının olumsuz etkilenmesi, ücretlerin düşük ve sosyal yardımların az olması, yoğun denetim nedeniyle baskının ve stresin artması, sosyal izolasyon ve sınırlı bir kariyer gelişimi olarak sayılabilecek önemli sorunları beraberinde getirdiği görülmüştür.

Sağlık ve sağlık uygulamalarına verilen değerin artmasına ek olarak son yıllarda hastalıklarda görülen artış, psikolojinin uzmanlık alanlarından biri olan sağlık psikolojisinin tüm dünyada ve ülkemizde önemini artırmaya başlamıştır. Bu çalışmanın amacı sağlık psikolojisinin tanımı ve sunuluş biçimi hakkında bilgi sunmak ve sağlık psikolojisi eğitiminin Türkiye’deki durumunu tespit etmektir. Bu amaçla, 2017-2018 öğretim yılında aktif olan Psikoloji bölümlerinin (21 devlet, 50 vakıf üniversitesi) lisans ve lisansüstü müfredat programları incelenmiştir. Lisans programlarının 56’sında (% 80) sağlık psikolojisi eğitimi sunulmaktadır. Lisans programlarındaki sağlık psikolojisi eğitiminin çoğunlukla seçmeli derslerle yürütüldüğü görülmüştür. Lisansüstü programların 14’ünde (% 18) sağlık psikolojisi ile ilgili bir ders bulunmaktadır. Bu oranlar uluslararası müfredat programlarında olduğu gibi Türkiye’de de sağlık psikolojisi eğitiminin, yaygınlaştırılması gerektiğine işaret etmektedir. Bunu destekler şekilde, Türkiye’de akredite edilmiş bir sağlık psikolojisi programı henüz bulunmamaktadır. Akreditasyon süreçlerinin başlaması ve sürdürülmesi Türkiye’deki müfredat programlarının standart ve sürekli hâle gelmesi ile mümkün olacaktır.

Gazeteler günlük olayları halka aktaran en önemli yayın organlarındandır. Mondros Ateşkes Antlaşması sonrası Anadolu’nun işgal edilmesi, özellikle 15 Mayıs 1919’da İzmir’in işgali halk nazarında büyük bir hezeyan uyandırmıştır. Bu işgallere karşı Müdafaa-yı Hukuk ve Redd-i İlhak Cemiyetleri vasıtasıyla Kuva-yı Milliye kurulmuştur. Bu süreçte Anadolu işgallerinin haksız yere yapıldığını ve işgale karşı direnişi desteklemek için Anadolu’da birçok yayın organı faaliyette bulunmuştur. Milli Mücadele dönemine katkı sağlayan en önemli gazetelerden birisi de Kastamonu’da yayın hayatına başlayan Açıksöz gazetesidir. Bu çalışmada, Bursa ve civarında Yunan işgali döneminde yaşanan gelişmelere değinilmiştir. Bu gelişmeler Açıksöz’den edinilen bilgiler çerçevesinde değerlendirilmiş olup aynı zamanda arşiv belgeleri ve telif eserlerden de yararlanılmıştır. Böylece gazetenin zor bir dönemde önemli bir görevi yerine getirme çabası ve Yunan işgali döneminde resmî kayıtların haricinde yaşanılanlar incelenmeye çalışılmıştır. İşgal döneminde sivillerin maruz kaldığı durumlar, işgalcilerin mezalimle birlikte tahrip ve tahkir politikası, bu çalışmanın içeriğini oluşturmaktadır.

Toplumsal cinsiyet rollerinin öğrenilmesinde güçlü etkileri olan etmenlerden biri de medyadır. Medyada yer alan içerikler Albert Bandura’nın sosyal öğrenme kuramına göre değerlendirildiğinde medyanın gözlemleme yoluyla bireylerin düşünce, tutum ve davranışlarını etkileyebildiği görülmektedir. Dünya genelinde milyonlarca kullanıcıya sahip olan ve Türkiye’de de özellikle çocuklar ve gençler olmak üzere geniş bir kullanıcı kitlesi bulunan dijital oyunlar oyuncularını farklı şekillerde etkileyebilmektedir. Bu çalışmada öğrenmede etkili olan etmenlerden dijital oyunlar toplumsal cinsiyet işaretleri bağlamında incelenmiştir. Çalışma kapsamında dünya genelinde 2019 yılının en çok satan oyunlarından Grand Theft Auto V, FIFA 20, Minecraft: PlayStation 4 Edition, Call of Duty: Modern Warfare, Tom Clancy’s Rainbow Six: Siege ve NBA 2K19 örneklem olarak seçilerek içerik ve betimsel analiz yöntemleriyle değerlendirilmiştir. Sonuç olarak oyunların genel itibariyle toplumsal cinsiyet eşitsizliğini yinelediği ve desteklediği tespit edilmiştir.
KÜÇÜK İSKENDER’İN “BERLİN” ADLI ŞİİRİNDE İĞRENÇLİK EKSENİNDE POSTMODERN GOTİK VE GROTESK ESTETİĞİ
Authors: DOĞAN Mine Nihan
Published: July 2021

Türk Yeraltı şiirinin travmatik, Beatnik-Marjinal şairi küçük İskender’in (1964-2019) alt kültürün egemenliğini anlatan “Berlin” adlı şiiri, Bu Defa Çok Fena (2011) adlı şiir kitabında yer alır. “Küçük” sıfatının küçük /k/ ile başlamasını isteyen şair, herkesin kendisini büyük gördüğü yazın dünyasında kendini küçük harflerle ifade etmeyi seçer. Küçük İskender’in psikolojik travmalarından doğan imgeleri ve iğrençlik eksenindeki gotik ve grotesk estetiği “Berlin” adlı postmodern şiirinde yinelenen ikonografik birer motiftir. Şair, Amerika’daki Beat kuşağından etkilenerek menşei Beyoğlu olan Beatnik-Marjinal “Berlin” şiirinde bir tabu olarak görülen duvarının yıkıldığı Berlin şehriyle Freud’un “özdeşleşme” kavramı çerçevesinde imgeler kurgular. Bu çalışmada “Berlin” şiiri Romantik edebiyatın “yüce”, Freud’un “tekinsiz”, Kristeva’nın “iğrenç” ve Bataille’ın “biçimsiz” kavramları başta olmak üzere çeşitli görüşler etrafında gelişen iğrençlik, gotik ve grotesk estetik bağlamında incelenecektir.

Türkiye Cumhuriyeti’nin kurucu kadrosu cumhuriyetin kökleşmesi, inkılapların benimsenmesi, devletin cumhuriyet idaresi altında, gelişerek geleceğe uzanabilmesi için çocuğun yetiştirilmesine özel bir önem vermiştir. 1930 ve 1940’lı yıllarda cumhuriyetin temel prensiplerini benimsemiş, evrensele kapılarını kapamamış kültür milliyetçileri yetiştirmek amacıyla nitelikli süreli yayınlarla çocuğa ulaşılmaya çalışıldığı görülmektedir. 29 Ekim 1938 tarihinde yayın hayatına giren ve 52 sayı yayımlanan Cumhuriyet Çocuğu edebî, eğitici ve öğretici içeriğiyle dikkat çeken bir süreli yayındır. Dergide hikâyeler, roman-çizgi roman tefrikaları, şiirler, resimler, karikatürler, bilmeceler, tabiat-tarih-coğrafya-fen bilgisi-Türk kültürü ve farklı kültürlerle ilgili yazılar vardır. Cumhuriyet idaresinde bir hukuk devleti içinde vatandaş olma bilincini telkin eden Cumhuriyet Çocuğu geçmişe ve değerlere bağlılığa son derece önem vermiş, Türklük çocuğu vurgusu yaparak milli kimlik ve aidiyeti ön plana çıkarmıştır. Türkiye’nin dört bir yanına Cumhuriyet Çocuğu dergisinin Ziya Gökalp’ın milli kültür ve medeniyet sentezi doğrultusunda “cumhuriyet çocuğu / vatandaşı” kimliği sunma çabası incelenecektir.
GÖÇMEN KİMLİKLERİNİN İNŞASI: BİR ÇOKKÜLTÜRLÜLÜK VE TANINMA TEORİSİ ELEŞTİRİSİ
Authors: GÖKSEL Gülay
Published: July 2021

Bu makalede ilk olarak çokkültürlü politikalar hakkındaki tartışmaların ve Honneth’in tanınmaya dayalı eleştirel teorisinin kısa bir özeti verilecektir. İkinci olarak Honneth’in teorisine iki açıdan eleştiri getirilecektir. İlk eleştiri, Honneth’in Meadçi sosyopsikolojik öz-oluşum analizinin, ev sahibi ülkelerdeki yeni gelen göçmenlerin saygısızlık ve yanlış tanınma deneyimlerini anlamamız için gerekli teorik yapı açısından eksik olduğudur. İkinci temel eleştiri, Honneth’in tanınma teorisini pratik sosyolojik bir bakış açısıyla uygulanabilir kılmak için siyasi kurumların bireysel kendini gerçekleştirme ve tanınma üzerindeki etkilerini göz ardı ettiğidir. Hegel’in etik düzen fikrini kullanmasına rağmen Honneth’in teorisi bireysel veya grup mücadelelerinin özgürleşme potansiyeli üzerinde siyasi kurumların rolüne vurgu yapmak konusunda yetersiz kalmaktadır. Farklı göçmen deneyimlerine referanslar verilerek bu eleştirilerin temel aldığı esas noktalar gösterilecektir. Son olarak göçmenlerin özgürleştirici potansiyelini veya topluma dâhil edilme süreçlerini daha iyi anlamak için tanınma teorisinin birkaç temel değişiklikle birlikte liberal veya komünitaryan teorilerden daha iyi bir teorik açıklama sağladığı savunulacaktır.
SANAYİ TOPLUMLARI BAĞLAMINDA DAHRENDORF’UN SINIF ANLAYIŞI
Authors: ERDOĞAN Umut
Published: July 2021

Sınıf ve sınıf çatışması sosyolojide üzerinde en çok tartışılan alanlardan biridir. Çatışma kuramının önemli isimlerinden Ralf Dahrendorf ise bu tartışmaya sanayi toplumlarında sınıf ve sınıf çatışmasının nasıl bir değişim yaşadığını “Class and Class Conflict in Industrial Society” adlı çalışmasında ele almıştır. Dahrendorf’a göre klasik Marksist anlayışın aksine sanayileşme sonrasında sınıf çatışmasının işçi sınıfı ve kapitalistler arasında artık gerçekleşmesi mümkün değildir. Sanayi toplumlarında yaşanan değişimler işçi sınıfının ve kapitalistlerin yapısını değiştirmiştir. Her iki sınıf da kendi içinde farklı çıkarlar ve konumlara göre bölünmüş hâldedir. Öte yandan Dahrendorf, bir çatışma kuramcısı olarak çatışmanın sanayi toplumlarında ortadan kalkmadığını söyler. İşlevselci teoriden de etkilenen Dahrendorf, çatışmanın işlevselleşmesinden bahseder. Bu çalışma bağlamında Dahrendorf’un “Class and Class Conflict in Industrial Society” (1959) tarihli eseri temel alınarak önde gelen çatışma kuramcılarından biri olan Dahrendorf’un sanayi toplumlarında değişen sınıf ve sınıf çatışması üzerine düşünceleri aktarılacaktır.
