Responding to Globalization and Urban Conflict: Human Rights City Initiatives
Authors: Smith Jackie
Published: March 2018

Expanding globalization and urbanization have intensified the threats to human rights for many vulnerable groups and have restricted resources available to the primary guarantors of these rights—local authorities. Human rights cities initiatives are bottom-up efforts to advance human rights implementation in local contexts. They are emerging around the world in response to the global pressures on cities that intensify urban inequality and conflict. In this article I discuss how global changes are impacting cities and their abilities to protect the basic rights of residents. I then discuss the human rights cities model as a strategic response of social movements to secure people’s basic needs and strengthen local mechanisms for addressing social conflicts. I provide detailed analysis based on participatory research with Pittsburgh’s Human Rights City Alliance between 2013 and 2016. Drawing from literature on international peacebuilding, I argue that human rights cities are an emergent model of peacebuilding and governance that can guide policy and planning at multiple levels. Human rights movements are challenging neoliberal globalization’s emphasis on economic growth and putting forward frameworks that prioritize the needs of people and communities. In their appeals to international human rights norms, human rights cities advocates both advance international law and governance while giving voice to inherent contradictions between human rights and the policies of economic globalization.

Defending Family Unity as an Immigration Policy Priority
Authors: Sullivan Michael
Published: March 2018

In this article, I make a policy argument in defense of family and relationship-based immigration preferences in U.S. immigration law that accounts for economic objections and calls for solidarity among socioeconomically disadvantaged U.S. residents on this issue. I begin with a historical account of policy arguments for limiting family-based immigration. I challenge the view that family-based immigration is a fiscal burden on the nation as a whole and acts against the interests of disadvantaged native-born workers. Then, I present and respond to perception-based objections to family-based immigration by disadvantaged citizens who believe that they are suffering from competition with mixed-skilled immigrants, including those sponsored by family members. Advocates of family unity in immigration policy are fighting the perception of zero-sum competition between immigrants and disadvantaged citizens by organizing together for improvements in wages and working conditions, leveraging arguments from the U.S. civil rights struggle to advocate for inclusive immigration policies.

Participatory Filmmaking Pedagogies in Schools: Tensions Between Critical Representation and Perpetuating Gendered and Heterosexist Discourses.
Authors: Rogers Matt
Published: March 2018

Although participatory media practices are often adopted to address social issues with youth in school and community contexts, there is a lack of critical analysis of the visual and discursive representations that organize student-produced participatory films. To respond to this concern, I employ critical discourse analysis to examine a series of films that were created for a New Brunswick school-based participatory filmmaking program that I coordinate, called What’s up Doc? Since the project’s inception in 2009, students have produced over 60 films that have raised institutional critiques, troubled inequitable discourses, and addressed social justice issues. Drawing attention to discourses that framed students’ films, I show how the work may perpetuate, rather than fully resist, marginalizing discourses, narratives, and visual representations. In particular, I show how the films may reproduce and authorize sexist discourses, demeaning narratives, and heteronormative assumptions. Youth may have undertaken filmmaking to generate social commentary and resist inequity, but critical engagement with the What’s up Doc? program demonstrates how discursive power operates on, in, and through participatory media texts.

Towards Sensorial Approaches to Visual Research with Racially Diverse Young Men
Authors: Tabi Emmanuel , Rowsell Jennifer
Published: March 2018

This is a collaborative ethnographic research project that highlights the artistic, literary contributions of racially diverse young men. It uses Critical Race Theory to question conventional, Eurocentric educational approaches that historically and currently continue to suppress various socially and culturally learned modes of communication. This article presents two research projects in urban and suburban formal and informal educational institutions to highlight multimodal literary approaches. The first project is an amalgamation of two critical, ethnographic case studies that explores how racially diverse young men express their literacy through rap and spoken word poetry. The second project uses ethnographic methods to observe racially diverse young men’s production of films and photographs in high school, community centers, and art gallery spaces. This study uses visual methods coupled with affect and sensory-laden approaches to collect data and conduct an analysis. The article reflects on conversations surrounding young men, particularly racialized young men, their relationship with literacy, and how these conversations are founded on their failure and deficit language about their literacy repertoires. We believe that such research is closely tied with other social justice themes and modes of inquiry. This article steers away from the ways racialized young men do not use literacy, and focuses instead on the ways that they do use literacy. Their literacy practices are predominantly visual in nature, frequently accompanied by other modes such as words and moving images. Fitting within the scope of the special issue on social justice and visual methods, we argue for a greater acknowledgement and analytical gaze on sensory and affective nuances within visual research. This approach adds texture and volume to interpreting racialized young men’s narratives. Interrogating their visuals and talking through their narratives that have agentive qualities gives both researchers an awareness of young men’s emotional worlds, and how the visual allows for sense-laden, agentive meaning-making.

Graphic Narratives, Trauma and Social Justice
Authors: Donovan Courtney , Ustundag Ebru
Published: March 2018

In this paper, we explore the relevance of graphic novels to understanding and responding to the complex nature of traumatic experiences. We argue that graphic narratives of trauma, which combine visual images and written text, significantly differ from biomedical and legal accounts by presenting the nuances of traumatic experiences that escape the conventions of written testimony. Building on the literature that integrates social justice concerns with visual methods and graphic medicine, we contend that graphic narratives effectively convey the complexities of traumatic experiences, including embodied experiences that are not always apparent, intelligible, or representable in written form, leading to greater social recognition of the dynamics and consequences of trauma. To illustrate this claim, we analyze Una’s Becoming Unbecoming (2015), a graphic novel that explores themes relating to trauma and social justice. Una relies on the graphic medium to explore the interconnections between personal and collective experiences of gender-based violence, and to show how physical embodied experience is central to her own experience of trauma. Graphic narratives like Becoming Unbecoming also offer a space for addressing the emotional, physical and financial costs of survivorship that usually are not available in legal written testimonies, potentially leading to better justice outcomes for trauma survivors in terms of social intelligibility and recognition, and access to social resources for healing.

The Epistemological and Ethical Value of Autophotography for Mobilities Research in Transcultural Contexts
Authors: Butz David , Cook Nancy
Published: March 2018

This article responds to calls from mobilities scholars for methodological innovation and reflexivity by (a) detailing our use of autophotography in a study of the everyday implications of a newly-constructed road for a small community in mountainous northern Pakistan, and (b) assessing autophotography’s attributes as a visual/narrative method for mobilities research in that setting, on ethical and epistemological grounds. We demonstrate that autophotography’s anti-objectivist epistemology of vision and participant-driven character, the portability and easy user-interface of compact cameras, and the inseparable mix of visual and narrative data the method produces, combined to attenuate epistemic injustice in our research, while also generating productive insights regarding the movements, representations and embodied practices our research subjects associate with the road. These points are developed with reference to literature on visual methods, mobile methods and subaltern autoethnography, as well as to the visual/narrative representations produced by study participants. The article concludes by exemplifying how research subjects used the road and its associated mobilities as discursive resources for the constitution of collective identity: to position their community in relation to modernity and tradition, to distinguish the community from its neighbours, and to articulate worries about the consequences of rapid social change.

Reinforcing Consumers’ Impulsive Buying Tendencies through M-Devices and Emails in Pakistan
Authors: Waheed Abdul , Yang Jianhua , K. Webber Jon
Published: March 2018

Aim/Purpose: The current study investigates the relationship between mobile and email marketing and consumer impulse buying tendencies in Pakistan.

Background: Technology has become a primary driver for all business operations, which has dramatically transformed the wireless communications marketing paradigm. However, researchers have claimed that further inquiry is still needed to explore the role that distinct and emerging global technologies have on marketing communication strategies. This study explores the linkage of mobile and email marketing on consumers’ impulse buying behavior in Pakistan.

Methodology: Primary data were collected through the distribution of 1000 questionnaires among students of different universities within two provinces of Pakistan: Punjab and Khyber Pakhton Khan (KPK). The study was conducted between November 2016 and March 2017. The authors received back 950 surveys, which is a very significant rate of return (95%). Of those submitted, 900 surveys were deemed eligible for analysis after improper documents were eliminated. Structure equation modeling (SEM) was utilized to test the study’s hypotheses.

Contribution: This study assists organizations in improving marketing campaigns by focusing more on mobile devices (m-devices) and email medium to better comprehend consumers’ assessment processes at a lower budgetary cost. Such digital considerations could provide innovative possibilities for marketers in approaching their target market by adopting novel methods for information sharing.

Findings: The findings revealed a positive association between mobile and email marketing on consumers’ impulse buying tendencies. The comprehensive analysis affirmed; however, there is a higher positive relationship of mobile marketing results compared to email marketing outcomes. There are favorable benefits in considering such emerging methods in marketing communications as promotional strategies are considered by organizations.

Recommendations for Practitioners: Marketers are encouraged to evaluate the potential of using both emerging mediums to take advantage of consumer impulse buying habits where m-devices and emails approaches are utilized.

Future Research: Future inquiries might examine the global influence of m-devices and email technology toward other buying tendencies of consumers: exploratory, online, variety seeking, habitual, and other emerging complex on-demand buying behavior.
DOĞALGAZ BORU HATLARINDA KOMBİNE BASINÇLI HAVA KURUTUCUSU TASARIMI
Authors: USTA Hüseyin , TUNCER Azim Doğuş , VATANSEVER Mustafa
Published: March 2018

Boru hatlarında gaz
sevkiyatı başlamadan önce iç yüzeyin kurutulması gerekmektedir. Bu gereklilik
ürüne ve kullanıma bağlı olarak değişmekle birlikte, boru hatlarında iç
korozyon oluşmasını önlemek ve taşınacak üründe istenen nem özelliklerini
karşılamak olarak sıralanabilir. Kurutma sırasında boru içerisindeki sıvı ya da
buhar haldeki suyun ve yabancı maddelerin uzaklaştırılması amaçlanmaktadır. Bu
çalışmada doğalgaz boru hatlarının kurutulması için geliştirilen “Gaz soğutmalı
ve ısı geri kazanım eşanjörlü, ısıtıcısız adsorpsiyonlu kombine basınçlı hava
kurutucu” önerilmektedir. Mevcut sistemlerdeki eksiklikler dikkate alınarak ve
gerekli iyileştirmeler ile faydalı bir kombine basınçlı hava kurutucusu modeli
tasarlanmıştır.  Bu model tasarlanırken,
hat kuruma süresini azaltan, enerji verimli ve uzun ömürlü olması hedefleri ön
planda olmuştur. Bu sistemde ısı geri kazanım ünitesi bulunduğu için enerji
ekonomisi sağlanacatır. Kurutmanın ilk aşamasında soğutma ile bir mıktar
kuruyan hava daha fazla nem tutma özellğine sahip olacaktır ve bu sayede
kurutma süresi kısalacaktır. Kurutma işlemi sadece doğalgaz için değil; etilen
ve propilen gibi petrokimyasallar, karbon dioksit, etan vb. ürünler için de
geçerlidir.

Titanyum ve alaşımları, mükemmel ısı direnci, korozyon direnci, tokluk, mukavemet, yüksek çalışma sıcaklığı ve düşük ağırlık oranına sahip oldukları için uzay-havacılık, otomotiv, kimya-petrokimya ve biyomedikal gibi çeşitli endüstrilerde yüksek mühendislik alaşımları olarak kullanılmaktadırlar. Ancak bu alaşımlar düşük işlenebilirlik derecelerine sahiptirler. Titanyum ve alaşımlarının işlenmesinde yüzey bütünlüğü ve kesici takım aşınması gibi problemlerle karşılaşılmaktadır. Bu çalışmada, titanyum ve alaşımlarının delinmesinde, frezelenmesinde ve tornalanmasında kesici takım malzemeleri, aşınma mekanizmaları, kesme kuvvetleri, yüzey pürüzlülükleri gibi konular gözden geçirilmiştir. Ayrıca, bu alaşımların işlenmesinde karşılaşılan zorluklar değerlendirilmiş olup yapılmış literatür çalışmaları ayrıntılı olarak ele alınmıştır.
Grafen Nanolevha Takviyesinin AlSi10Mg Alaşımının Mikroyapı ve Mekanik Özellikleri Üzerine Etkisi
Authors: KANDEMİR Sinan
Published: March 2018

Bu çalışmada, birkaç
grafen tabakasından oluşan, 100 nm’nin altında kalınlığa ve olağanüstü mekanik
özelliklere sahip grafen nanolevhaların (GNL) endüstride sıkça kullanılan
AlSi10Mg alaşımına katkısının mikroyapı ve mekanik özellikler üzerine etkisi
incelenmiştir. Büyük yüzey alanı ve sahip oldukları yüksek yüzey enerjileri
nedeniyle GNL’ların sıvı metaller içinde homojen olarak dağıtılması güçtür.
GNL’ların sıvı alüminyum alaşımına geçişi yarı-katı mekanik karıştırma ile
matris içinde dağılımı ise ultrasonik proses ile gerçekleştirilmiştir. Dökülen
kompozitlerin yapılan mikroyapı analizleri sonucunda, yüksek yoğunluktaki
ultrasonik dalgalar ile GNL’ların aglomerasyonlarının önlenerek matris içinde
görece homojen olarak dağıtıldığı ve matris-GNL’lar arasında iyi bir tutunma
yüzeyinin elde edildiği gösterilmiştir. Gerçekleştirilen çekme deneylerinde,
ağırlıkça %0.25 GNL takviyesinin alaşımın mukavemetini önemli oranda arttırdığı
tespit edilmiştir. Mukavemetteki iyileşme ağırlıklı olarak GNL’ların
dislokasyonların ilerlemesinde bariyer vazifesi görmesine dayandırılmaktadır.
Bu sonuçlar GNL takviyeli yüksek performanslı metal matrisli nanokompozitlerin
seri imalata uygun olarak sıvı fazda üretilebilirliklerini göstermektedir.

Case Study of the Didactic Transposition of Teaching Quadratic Functions Using Realistic Mathematics Education and a Traditional Approach: Two Teachers’ Implementations and Reflections
Authors:   The Korea Society Of Educational Studies In Mathematics, Lim Woong , Lee Kyeong-Hwa
Published: March 2018

Realistic Mathematics Education (RME) is a didactic approach to teaching school mathematics through meaningful contexts. This method involves transposing the discipline of mathematics into a special kind of mathematics for students, or vice versa where students mathematize the contexts and engage in learning mathematics. Alternatively, traditional teaching models involve the transfer of mathematical knowledge held by the teacher to the students who are recipients of the knowledge. A scholarly approach of teachers and researchers teaching these two different methods merits a detailed examination. In light of this need, this study investigates two teachers’ experiences of the use and implementation of both an RME approach and a traditional teaching method with the same instructional goal of solving quadratic optimization problems. The findings of this study suggest that various forms and transformations of the knowledge of the Didactic Transposition theory emerged as an important area in the design and implementation of a mathematics lesson. In particular, the RME approach afforded students with diverse backgrounds rich opportunities to engage in mathematics and produce productive mindsets toward mathematics. Further, our findings illustrate how the teachers engaged in a professional discourse for the lesson analysis, and how they reflected on the ways that a teaching method could present challenges, barriers or opportunities in the classroom. We concluded that the implementation of two conflicting pedagogies could serve as a meaningful opportunity of learning, whereby teachers were able to connect the Didactic Transposition theory to practice, and reflect on the pedagogical realities of teaching school mathematics.

Factors Affecting and Outcome of Radioactive Iodine Therapy in Hyperthyroidism: A study at Institute of Nuclear Medicine & Allied Sciences (INMAS), Sylhet
Authors: Nahar Kamrun , Akhter Papia
Published: March 2018

Objective: Radioactive iodine therapy (RIT) is the most commonly used modality to treat hyperthyroidism and is indeed in most cases, the treatment of choice. The aim of this study was to assess the clinical outcome one year after radioactive Iodine-131 (RAI -131) therapy and to identify the factors associated with response of the therapy.Patients and Methods: A total 107 hyperthyroid patients were included in this study. All patients were pre-treated with anti-thyroid drugs (ATD). A fixed dose of 8 mCi of radioiodine was given to the patients with Graves’ disease, 12 mCi to patients with single toxic adenoma and 15 mCi to patients with toxic multi-nodular goiter . The patients were done serum FT4 initially and followed up with serum T3, T4, and TSH at three months , six months and one year of RAI therapy . The clinically and biochemically euthyroid and hypothyroid patients were considered as cure of the disease.Results : The cure rate was about 94.7% seen in female patients and 93.8% in male ( P=0.92), 93.6% in younger age group (below 40 years) and 95.0% of the older patients ( P=1.51), 95.5% of the patients who were taking ATD for more than one year and 92.7% of the patients who were taking ATD for less than one year before therapy( P=1.95), 95.4 % of the patients who had initial FT4 level less than 35 pmol/L and 92.7 % of the patients who had high initial FT4 ( P=1.54). Cure rate of Graves’ disease was 45/53 (92.5%), multi-nodular goiter 41/43 (95.3% ) and for single toxic adenoma was 11/11 (100% ) (P= 0.65). The incidence of radioiodine induced hypothyroidism was 6.5 % at three months, 13.1 % at six months and 15.0 % at one year. Overall incidence of cure rate of RAI therapy after one year was 101 (94.4 %).Conclusion: No statistically significant difference was found in the cure rate when sex, age, duration of pretreatment with antithyroid drug, initial FT4 level and cause of hyperthyroidism were considered.   From this study it can be concluded that cure rate of RAI therapy is quite good and the pretreatment factors have little influence on the final outcome.Bangladesh J.

Published: March 2018

Objective: To assess the clinical indications and spectrum of MDP bone scan findings in paediatric patients referred to the National Institute of Nuclear Medicine and Allied Sciences (NINMAS).Materials and Methods: Paediatric patients, age ranged from 2-18 years referred to NINMAS from January 2014 to November 2015 for bone scintigraphy were included in this study. All patients had 99mTc MDP bone scan for various clinical indications. The spectrum of clinical indications and bone scan findings were recorded and analyzed.Results: Total 2323 bone scans with 99mTc MDP were done in NINMAS in the above mentioned period. Among them 91 (3.917%) cases were in paediatric age group. Of which 82 (90.11%) patients with known malignancy were referred for radionuclide skeletal survey. The most common clinical indications were osteosarcoma 30 (32.96%) cases and Ewing’s sarcoma 25 (27.47%) cases followed by five neuroblastoma (5.49%), four (4.39%) rhabdomyosarcoma, three (3.29%) Langerhans cell histocytosis and rest others. Bone scan was positive in 58 (63.7%) cases and normal in 33 (36.3%) cases. Out of 58 cases 38 had features of primary bony lesion, 10 cases had multiple metastases, four cases had primary bone tumour of Ewing’s sarcoma as well as metastases.Conclusion: Bone scan is a popular imaging modality for skeletal survey of paediatric patients in malignancy, both primary and metastatic bone diseases. Bone scanning in paediatric patients contributes a major role in detecting the cause and localizing the pathology of bone. High quality imaging, interpreted by physicians familiar with paediatric diseases, correlation with clinical records and other imaging are mandatory to maximize the benefit.Bangladesh J.

A total of 104 patients with bronchial mass lesion were included in the study. Thorough history, clinical examinations, X-ray chest, CT chest and CT guided fine needle aspiration cytology (FNAC) were done. This study was carried out in the department of Radiology and Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU) and Dhaka Medical College Hospital (DMCH) from July 2009 to June 2010. Diagnosis of hilar and mediastinal involvement in bronchogenic carcinoma by CT scan was highly sensitive and specific. CT findings of the present study correlated well in most of the cases with the CT guided FNAC results. It can therefore be concluded that CT scan is a useful modality in the evaluation of hilar and mediastinal involvement in bronchogenic carcinoma.Bangladesh J. Nuclear Med. 19(1): 32-37, January 2016
Assessment of Internal Radiation Dose in Gastro Intestinal Tract for Acute Ingestion of Ra-226 of the People of Bangladesh
Authors: Quddus AHMR , Zaman MMA , Mollah AS , Zaman MM
Published: March 2018

To design appropriate method for treatment planning it is necessary to know the precise radiation dose absorbed by any internal organ in human body. This paper will provide a method for calculating retention, absorbed dose, committed equivalent dose and committed effective doses due to acute ingestion of 1 Bq of Ra-226 in the gastro intestinal (GI) tract of Bangladeshi people for different age groups. Calculations are done by using “Internal Radiation Dose Assessment (IRDA)” software which has been developed in Visual Basic language. GI tract consists of four tissue compartments, e.g. stomach (ST), small intestine (SI), upper large intestine (ULI) and lower large intestine (LLI). One hour after the ingestion, the retention and absorbed dose show the trend ST > SI > ULI > LLI. For tissue compartments the variation of the committed equivalent dose pattern is LLI > ULI > ST > SI for the radionuclide. The variation of absorbed dose, committed equivalent dose and committed effective dose with respect to age follow the pattern: 1 year> 10years > adult female > adult male. The highest committed effective dose is found in the GI tract of 1 year old child. For other age groups these values are slightly less than those for 1 year old child.Bangladesh J.

Authors: Nisa Lutfun , Quadir Kamila Afroj , Begum Shamim MF , Hussain Raihan , Hasan Mizanul
Published: March 2018

Introduction: Targeted alpha therapy (TAT) is a new experimental therapy that targets cancer cells and tumor capillary endothelial cells through intravenous injection of an alpha immuneconjugate (AIC). The AIC is formed by labeling the cancer targeting vector (monoclonal antibody) with alpha emitting radioisotopes using a bifunctionalchelator. The monoclonal antibody (MAb) is raised against antigens (e.g. MUC1) over-expressed on the surface of certain cancer cells. There are several centers notably in Europe, the US and Australia that are actively involved in TAT clinical trials of different cancers using a variety of techniques, alpha emitters and MAbs. Observations from their cumulative experience suggest that TAT is safe and effectivebut needs further trials for practical acceptance. Especially critical is the issue of maximum tolerance dose (MTD) which needs to be established for maximum target kill. Bangladesh has the infrastructure to conduct aTAT clinical trial and can significantly add to the growing pool of data for advanced treatment of cancers through collaborative involvement in targeted alpha therapy research.Objective: The aim of the article is to present a general overview of targeted alpha therapy and to discuss the feasibility of a TAT clinical trial in Bangladesh in the context of current cancer management situation in the country.Method: Literature review of significant publications was done to obtain an update of the current status of targeted alpha therapy. Relevant issues of TAT are presented for a theoretical basis of the technology. Next, the methodology of a proposed clinical trial is discussed, together with the practicability of its introduction in Bangladesh.Conclusion: Implementation of TAT clinical trial will help to develop an advanced technology and build- up skilled manpower in Bangladesh.It will optimize the key parameters of targeted alpha therapy, i e stability and specific activity of the alpha-conjugate and establish the maximum tolerance dose for the AIC. If the clinical trial is successful, it can change the prognosis of many end-stage cancers. Patients in Bangladesh with advanced MUCI expressing tumors of the breast, ovary, pancreas and prostate can have some measure of hope with stability of the disease.Bangladesh J.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in men and the second in women globally. The incidence varies with geographic difference. In Bangladesh, hospital based cancer registry shows rate of CRC in male 10.1%- 12% and in female 3% - 12.0%. The prognosis of the disease and treatment planning depends upon the staging of the disease. Surgery is usually a common way of treatment of rectal cancer except some cases with advanced stage. Radiation therapy, often with chemotherapy, is frequently used in the adjuvant or neoadjuvant setting for the treatment of rectal cancers. External beam radiation therapy (EBRT) is a well practiced method of treatment in the in-operable cases of rectal cancer. 18F FDG PET-CT is a well recognized imaging tool in the pretreatment evaluation of colorectal cancer worldwide. Accurate staging is needed for proper selection of treatment and cost effectiveness. Here, we discussed a case of rectal cancer (stage IV) with post chemotherapy state with history of palliative loop iliostomy bypass. The patient was referred for 18 F FDG PET-CT scan for restaging of the disease and to localize functioning tumor site for external beam radiotherapy (EBRT) planning. FDG PET-CT imaging revealed FDG avidity at the primary tumor site, perircetal fat and multiple FDG avid hypermetabolic lymphnodes in pelvic cavity. A focal FDG avid lesion in anterior aspect of liver suggests hepatic involvement. The fusion PET-CT imaging has played an important role in the further management of the patient by providing guidelines in EBRT.
