Authors: Ao Xiao Hui , Xia Huan Xiong , Liu Jian Hua , He Qi Yang , Lin Sheng Xiang
Published: March 2021

Due to the temperature and concentration determine the kinetic undercooling of interface growth and nucleation undercooling inside the melt, they play an important role in the solidification microstructure of the alloy. In this paper, the effect of temperature gradient and cooling rate on the dynamic undercooling was studied and the mechanism of the concentration at the solid-liquid interface on the kinetic undercooling during the continuous cooling process was analyzed. A calculation method for the coupling of temperature and concentration during Inconel 718 alloy solidification was developed, which can solve the problem that the concentration and temperature are difficult to be calculated at the same time in the numerical calculation.

Published: March 2021

INTRODUCTION:

Peripheral blood stem cell has become the preferred source for hematopoietic stem cells in both autologous and allogenic transplants. CD34+ cells represent a small proportion of the leukapheresis product content. The present study aims to analyze the cellular composition of leukapheresis product collected by intermittent-flow Mobile Collection System®+ (MCS+) and continuous-flow (Spectra Optia®) apheresis equipment.

METHODS:

In this retrospective study, 97 leukapheresis procedures for 85 individuals mobilized only with granulocyte colony-stimulating factor were analyzed. The product samples were analyzed for CD34+ cells, red blood cells (RBCs), white blood cells, and platelet contents. The difference in overall product composition was compared between the equipment through Mann–Whitney U-test.

RESULTS:

Both the equipment had similar CD34 and mononuclear cells (MNC) harvested in the product. However, Spectra Optia had statistically significantly lower product volume than MCS+ (215 mL vs. 260 mL, P = 0.04). Similarly non-CD34 composition such as RBC content per apheresis was six-fold higher (27 mL vs. 4 mL) and platelet contamination (1601 vs. 1275 × 109/L) was relatively higher with MCS+ over Spectra Optia. No relationship was observed between the CD34 concentration in the product and RBC and platelet contamination between both the equipment.

CONCLUSION:

Both equipment collect adequate CD34 and MNC cells; however, Spectra Optia is preferred due to product quality in terms of less product volume with minimal RBC and platelet contamination.

Published: March 2021

Hepatitis C virus (HCV) and HIV have emerged as major viral infections within the past two decades, and their coinfection poses a big challenge with a significant impact in terms of morbidity and mortality associated with liver disease and renal failure. The current study aimed at assessing the prevalence of HCV infection and associated comorbidities among HIV patients at one primary health facility in Rwanda. In total, 417 HIV-positive patients were recruited and included in the study from January 1, 2019 up to June 30, 2019. All participants were screened for HCV infection by using the SD Bioline HCV antibody rapid test. In addition, underlying medical conditions were also recorded as comorbidities. Among 417 participants, 52 exhibited HCV-positive results (12.5%). The group of 41- to 50- and 51- to 60-year-olds had higher prevalence of HIV/HCV coinfection than other age-groups with 3.6% and 4.6%, respectively. Furthermore, five underlying medical conditions were found as comorbidities among the study participants. Those with HIV/HCV coinfection showed higher comorbidities than those with mono-infection including liver toxicity, P value 0.005; tuberculosis, P value 0.005; renal failure, P value 0.003; hypertension, P value 0.001; and diabetes mellitus, P value 0.001. The relative risk ratio of having comorbidities in those groups was 4.09. To conclude, the prevalence of HCV/HIV coinfection is high, and there was a statistical significant association of having comorbidities in HIV/HCV-coinfected group compared with the group of HIV mono-infection, which suggests more intervention in this vulnerable group of patients.

Published: March 2021

In Pakistan, the treatment of multidrug-resistant tuberculosis (MDR-TB) with a shorter treatment regimen (STR), that is, 4–6 months of amikacin, moxifloxacin (Mfx), ethionamide, clofazimine (Cfz), pyrazinamide (Z), ethambutol (E), and high-dose isoniazid, followed by 5 months of Mfx, Cfz, Z, and E, was initiated in 2018. However, there is a lack of information about its effectiveness in Pakistani healthcare settings. Therefore, this retrospective record review of MDR-TB patients treated with STR at eight treatment sites in Pakistan aimed to fill this gap. Data were analyzed using SPSS 23. Multivariate binary logistic regression (MVBLR) analysis was conducted to find factors associated with death and treatment failure, and lost to follow-up (LTFU). A P-value < 0.05 was considered statistically significant. Of 912 MDR-TB patients enrolled at the study sites, only 313 (34.3%) eligible patients were treated with STR and included in the current study. Of them, a total of 250 (79.9%) were cured, 12 (3.8%) completed treated, 31 (9.9%) died, 16 (5.1%) were LTFU, and four (1.3%) were declared as treatment failures. The overall treatment success rate was 83.7%. In MVBLR analysis, patients’ age of 41–60 (odds ratio [OR] = 4.9, P-value = 0.020) and > 60 years (OR = 3.6, P-value = 0.035), being underweight (OR = 2.7, P-value = 0.042), and previous TB treatment (OR = 0.4, P-value = 0.042) had statistically significant association with death and treatment failure, whereas patients’ age of > 60 years (OR = 5.4, P-value = 0.040) and previous TB treatment (OR = 0.2, P-value = 0.008) had statistically significant association with LTFU. The treatment success rate of STR was encouraging. However, to further improve the treatment outcomes, special attention should be paid to the patients with identified risk factors.
Reflection Full Waveform Inversion with Decoupled Elastic-wave Equations in Inhomogeneous Medium
Authors: Liang Zhanyuan , Wu Guochen , Zhang Xiaoyu , Li Qingyang
Published: March 2021

Reflection full-waveform inversion (RFWI) can reduce the nonlinearity of inversion providing an accurate initial velocity model for full-waveform inversion (FWI) through the tomographic components (low-wavenumber). However, elastic-wave reflection full-waveform inversion (ERFWI) is more vulnerable to the problem of local minimum due to the complicated multi-component wavefield. Our algorithm first divides kernels of ERFWI into four subkernels based on the theory of decoupled elastic-wave equations. Then we try to construct the tomographic components of ERFWI with only single-component wavefields, similarly to acoustic inversions. However, the S-wave velocity is still vulnerable to the coupling effects because of P-wave components contained in the S-wavefield in an inhomogeneous medium. Therefore we develop a method for decoupling elastic- wave equations in an inhomogeneous medium, which is applied to the decomposition of kernels in ERFWI. The new decoupled system can improve the accuracy of S-wavefield and hence further reduces the high-wavenumber crosstalk in the subkernel of S-wave velocity after kernels are decomposed. The numerical examples of Sigsbee2A model demonstrate that our ERFWI method with decoupled elastic-wave equations can efficiently recover the low-wavenumber components of the model and improve the precision of the S-wave velocity.
An unusual Barothermometer
Authors: Camuffo Dario
Published: March 2021

An unusual instrument, named “Barothermometer”, belonging to the collection of Villa Vigoni, on the Como Lake, Italy, is analysed. The instrument is composed of a U-shaped thermoscope and a spirit thermometer. Both instruments have their tubes placed side-by-side on the same frame and use the same scale. It measures the air temperature and the tendency of the barometric pressure to predict weather changes. A study is made to clarify the operating principle and produce the instructions for use. The development of the ideas to which the instrument has been inspired follows a tree starting with the Galileo’s thermoscope, the Amontons air thermometer and finally the Adie sympiesometer. The measuring method is typical of the first half of the 19th century, but the construction details in aluminium, the fonts used in the printed instructions and the colour fading suggest that the instrument was built around 1930-40.
Сашко-lect: The translanguaged grammar of a hyper multilingual global nomad. Part 2 – Contact mechanisms
Authors: Andrason Alexander
Published: March 2021

This study examines the idiolect of Сашко – a hyper-multilingual global nomad whose language repertoire draws on forty languages, ten of which he speaks with native or native-like proficiency. By analyzing grammatical and lexical features typifying Сашко’s translanguaging practices (code-switches, code-borrowings, and code-mixes), as documented in the corpus of reflexive notes that span the last twenty-five years, the author designs Сашко’s translanguaged grammar. Instead of being a passive additive pluralization of separated, autonomous, and static monolects, Сашко’s grammar emerges as a deeply orchestrated, unitary, and dynamic strategy. From Сашко’s perspective, this grammar constitutes a tool to express his rebellious and defiant identity; a tool that – while aiming to combat Western mono-culturalisms, compartmented multilingualisms, and nationalisms – ultimately leads to Сашко’s linguistic and cultural homelessness. This paper – the second in a series of three – is dedicated to language-contact mechanisms operating in Сашко-lect: code-switching and borrowing.
On Chinese Hui-Muslim elementary vocabulary (2): Funeral terminology
Authors: Mèngyáo Sūn , Knüppel Michael
Published: March 2021

With this paper the writers continue their series of articles on Chinese Muslim elementary vocabulary. As already mentioned in the first part,2 in most Chinese dictionaries the specific elementary vocabulary of Islam is omitted. The paper in hand deals with the funeral terminology of Chinese Muslim.3 In contrast to the prayer terminology, we can only find one direct borrowing in Sino-Arabic, but no Sino-Persian transcription (Arabic and Persian loanwords phonetically transcribed with Chinese characters) among the funeral terms. More often the common Chinese terms are also used in the specific Muslim context. Furthermore, it is obvious that the number of terms is somehow limited comparing to the prayer terminology.

Published: March 2021

Ciência do conhecimento humano, a epistemologia, também sustentáculo da prática pedagógica e das teorias da aprendizagem,é amparada por três vertentes conceituais - a inatista ou apriorista, a empirista e a interacionista - que, por sua vez, dão luz à diferentes abordagens de ensino e saberes pedagógicos que sustentam o processo de aprendizagem e ação docente na Educação Física e no esporte. O objetivo do estudo, assim, passou por elucidar os procedimentos de construção de um instrumento metodológico que mapeie as bases epistemológicas de profissionais e futuros profissionais de Educação Física e esporte, materializado pela aplicação de um questionário fechado com estudantes de graduação e pós-graduação dos cursos de Educação Física e Ciências do Esporte. O estudo, desse modo, tem natureza quali-quantitativa e caráter descritivo-exploratório.Ainda que tenham denotado maior aproximação aos preceitos pedagógicos interacionistas, houve, em maior ou menor medida, relevante identificação dos estudantes com as outras teorias do conhecimento. Evoca-se, assim, a importância de se fomentar reflexões quanto às teorias pedagógicas e epistemológica que sustentam a prática de ensino esportivo, de modo a minimizar contradições na ação docente.

Students’ Perceived Utility of Precision Taught Calculus
Authors: Dibbs Rebecca- Anne , Glassmeyer David , Yacoub Wafa
Published: March 2021

The last decade of calculus research has showed students learn best when lecture is supplemented with thoughtful use of technology and group work; however, educators are given little direction of how they are to balance the already full first semester calculus class. Precision teaching is an instructional model that employs formative assessment to provide information on what topics are understood by students as well as indicate troublesome concepts. With this information, the instructor can adjust class time accordingly by incorporating supplemental activities most beneficial to students. The purpose of this interview study was to explore the perceived utility of precision teaching by eight students earning to see if further exploration of this topic was warranted. Although precision teaching requires more work for the instructor, students’ high perceived utility makes precision teaching a valuable method of undergraduate instruction because they claim to study more, understand material better, and earn higher grades.
How Does My Research Question Come About? The Impact of Funding Agencies in Formulating Research Questions
Authors: Tarrozzi Massimiliano
Published: March 2021

It is a widespread claim that the research question should primarily come from a careful literature analysis (Creswell, 2007). Actually, it is basically a good suggestion, mainly for novices, to avoid the mistake of choosing a research method only for ideological reasons, and far from the phenomenon that one is willing to explore. However, this idea does not take into account other complex phenomena involved in constructing a research question. First of all, the epistemological framework, which is never neutral and performs what I am supposed to investigate; second, the kind of funding agency, which has an indisputable impact not only on the ethical - political level, but also on the methodological choices. In this paper I will compare, in the light of the research that I have conducted thus far, the methodological impact of different types of funding agency, particularly on the formulation of the research question itself.
Negotiating Responsibility for Navigating Ethical Issues in Qualitative Research: A Review of Miller, Birch, Mauthner, and Jessop’s (2012) Ethics in Qualitative Research, Second Edition
Authors: McCarron Michelle
Published: March 2021

Ethics in Qualitative Research (Miller, Birch Mauthner, & Jessop, 2012), now in its second edition, uses a feminist framework to present a variety of issues pertinent to qualitative researchers. Topics include traditional challenges for qualitative researchers (e.g., access to potential participants, informed consent, overlapping roles), as well as those that have garnered more attention in recent years, particularly with regard to uses and consequences of technological advances in research. The book is critical of committees whose function it is to review proposed research and grant research ethics approval (e.g., University Research Ethics Committees [URECs], Research Ethics Boards [REBs], and Institutional Review Boards [IRBs]). The authors of this book are situated within the United Kingdom. The editors take the position that ethics oversight by the researchers themselves is preferable and that such boards and committees are not well equipped to review qualitative research. A rebuttal to this position is presented within this review. Ethics in Qualitative Research provides a good overview of ethical issues that researchers face and is effective in merging theory with practice. It would be strengthened by avoiding the debate over URECs or by offering concrete suggestions for how URECs can improve their reviews of qualitative research.
Investigating Humor Within a Context of Death and Tragedy: The Narratives of Contrasting Realities
Authors: Vivona Brian
Published: March 2021

Crime scene investigators (CSIs) are subjected to many complexities of working in a context of death, trauma and tragedy. They experience this context in a more intimate manner than any other member of the criminal justice community. Within these challenging work settings in which human lives have ended, humor can emerge as crime scene investigators attend to their tasks. The research question this study addressed is “How is humor used to negotiate work experiences and make meaning from working in a context that includes death, trauma and tragedy?” CSIs were interviewed and provided narratives from their lived experiences regarding humor during their challenging work. Humans often use storytelling to frame and construct meaning of their lived experiences. For the CSI, the telling and retelling of stories of laughter and stories of tears has several individual and organizational outcomes, including group socialization, negotiating the stresses of the work and meaning making.
An Integrated Approach to Diabetes Prevention: Anthropology, Public Health, and Community Engagement
Authors: Page-Reeves Janet , Mishra Shiraz , Niforatos Joshua , Regino Lidia , Gingerich Andrew , Bulten Robert
Published: March 2021

Diabetes is an enormous public health problem with particular concern within Hispanic communities and among individuals with low wealth. However, attempts to expand the public health paradigm to include social determinants of health rarely include analysis of social and contextual factors considered outside the purview of health research. As a result, conceptualization of the dynamics of diabetes health disparities remains shallow. We argue that using a holistic anthropological lens has the potential to offer insights regarding the nature of the interface between broader social determinants, health outcomes and health disparity. In a primarily Hispanic, immigrant community in Albuquerque, New Mexico, we conducted a mixed methods study that integrates an anthropological lens with a community engaged research design. Our data from focus groups, interviews, a survey and blood sampling demonstrate the need to conceptualize social determinants more broadly, more affectively and more dynamically than often considered. These results highlight a need to include, in addition to individual - level factors that are traditionally the focus of public health and more innovative structural factors that are currently in vogue, an in - depth, qualitative exploration of local context, social environment, and culture, and their interactions and intersectionality, as key factors when considering how to achieve change. The discussion presented here offers a model for culturally situated and contextually relevant scientific research. This model achieves the objectives and goals of both public health and anthropology while providing valuable insights and mechanisms for addressing health disparity such as that which exists in relation to diabetes among Hispanic immigrants in New Mexico. Such an approach has implications for how research projects are designed and conceptualizing social determinants more broadly. The discussion presented provides insights with relevance for both disciplines.

A Journey of Pregnancy Loss: From Positivism to Autoethnography
Authors: Sell-Smith Julie , Lax William
Published: March 2021

When a dissertation research project exploring the impact of mind - body practices on symptoms of depression and anxiety in pregnant women with a history of miscarriage failed to yield statistically significant results, I struggled with how to demonstrate that I had gleaned knowledge from this project of nearly 3 years. When a series of parallel pregnancy losses occurred in my own life, I realized that I am heavily situated within the context of my research and need to consider my data in a different sense; one that acknowledges my own self within this process while attempting to capture the lived experiences of others. The shift to autoethnography afforded me the opportunity to demonstrate that knowledge can be generated through multiple methodologies, with one approach not being privileged over another. As this dissertation moved from an empirical study to a qualitative, autoethnographic piece, I was able to identify themes surfacing from the literature, my own experiences and participation in a pregnancy loss support group. The themes discussed include: making meaning from the experience, granting personhood status and grieving and other emotional expression.

Prospective Elementary Teachers’ Views on Their Teachers and Their Effectiveness
Authors: Karakas Mehmet
Published: March 2021

In this paper future elementary teachers reflect on their past experiences and talk about their teachers and the way they were taught, and portray the characteristics of effective and not so effective teachers. The study also highlights Turkish teachers` way of instruction and the strategies they use. Participants were 41 sophomore and 62 junior prospective elementary teachers enrolled in a small university in northeastern Turkey. Data were collected using mostly the document analysis techniques. Findings show that effective teachers are caring, loving, funny, and patient, show special in and out of class interest in students, and are fair to everyone. Not so effective teachers are out of temper, fear imposing, using abusive language, authoritarian, using violence, unfair and discriminating between students, and boring in class.
Bobby Fischer in Socio-Cultural Perspective: Application of Hiller’s (2011) Multi-Layered Chronological Chart Methodology
Authors: Ponterotto Joseph , Reynolds Jason
Published: March 2021

This article presents a case study application of Hiller’s (2011) Multi - Layered Chronological Chart (MLCC) methodology to the life story of former World Chess Champion Bobby Fischer. Designed for use in qualitative biographical studies, the MLCC is adapted here for psychobiographical research. In 1972, Fischer became an American Cold War hero as he wrestled the World Chess Championship from a half century of Soviet domination. His rapid rise to world fame was followed by infamy as Fischer abandoned competitive chess, grew increasingly Anti - Semitic and Anti - American, became a fugitive from U.S. justice, and died in relative isolation in Reykjavik, Iceland. Fischer remains one of the more enigmatic personalities of the 20th century and many questions remain regarding his psychological health. The MLCC method is used to contextualize Fischer’s life in nine key topical domains across five developmental life stages. The value of the MLCC methodology to psychobiographical research is highlighted and suggestions for advancing this methodology are put forth.
The Sexy Issue: Visual Expressions of Heteronormativity and Gender Identities in Cosmopolitan Magazine
Authors: Saraceno Michael , Tambling Rachel
Published: March 2021

The current study used a qualitative image analysis to explore observed interactional behaviors communicated through images printed in Cosmopolitan magazine during the calendar year of 2009 as a means to infer social values . Two general inquiries were used to guide the manner with which behavior was observed: is a heteronormative bias present and what values regarding the expressions of sexual orientation and gender identities can be inferred from these images. The sample consisted of 722 individual images depicting groups of two or more persons. Images were coded for group gender composition, activities engaged in, and physical touch . Results indicated a strong bias favoring heterosexual romantic/sexual intimacy and disfavoring homosexual romantic/sexual intimacy. The differences found between groups of womyn and groups of men suggest the expression of traditional hegemonic gender stereotypes in these image selections. Together, these findings suggest that traditional gender identities and heteronormative ideas were the dominant values communicated in these media image selections.
Graduate Students’ Perception of Standards and Accreditation in Higher Education in Turkey: A Qualitative Analysis
Authors: Yuksel Ismail
Published: March 2021

My aim in this this study was to investigate graduate students’ perceptions about the concepts of standard and accreditation and their views on the problems of accreditation in Turkey. I conducted research on 26 graduate students in Eskisehir Osmangazi University, Turkey. I administered an open - ended questionnaire consisting of four questions to collect the data. To analyze the data I used content analysis technique. The internal consistency of the study was found 0.81. My initial findings showed that the participants associated the concept of quality especially with reliability, first - class, and expensive which are commonly used; associated the concept of standard with criteria, similarity, and necessity which are confused much with; finally associated the concept of accreditation with quality assurance, auditing, and approval which are the among of its meaning. The results also manifested that the accreditation cycle of higher education in Turkey had crucial barriers as improper standards lack of accreditation board, and institutional issues. I hope that my findings will enlighten researchers about the main issues associated with accreditation in Turkey, and encourage stakeholders to refocus on the inactive accreditation system.

Letters to Grandma: A Comparison of Generational Perspectives of Women's Growth as Higher Education Faculty
Authors: Palmer Elyn
Published: March 2021

This ethnographic compilation is the result of a course exercise in qualitative research. A current student of Texas Tech University interviewed an 87-yearold faculty member from the 1950s, comparing her experiences to those of the author in similar, present-day academic environments. The author developed the format of the paper as letters between a young faculty member and her experienced grandmother. Results of the study reflect many similarities between the experiences of past female faculty members and female faculty of today; the exercise does convey, however, many advances for women in the academic culture as well. Finally, the recorded experiences of the older woman support those scenarios highlighted in the study of higher education’s history.

A Critical Dialectical Pluralistic Examination of the Lived Experience of Select Women Doctoral Students
Authors: Onwuegbuzie Anthony , Rosli Roslinda , Ingram Jacqueline , Frels Rebecca
Published: March 2021

The purpose of this study was to explore and to understand the daily life experiences of 8 women doctoral students who were in pursuit of their doctorates. A partially mixed concurrent dominant status design was utilized in this study embedded within a mixed methods phenomenological research lens and driven by a critical dialectical pluralistic philosophical stance. Specifically, these 8 students were interviewed individually to examine their lived experiences as doctoral students. The interview responses then were subjected to a sequential mixed analysis that was characterized by 2 qualitative analyses (i.e., constant comparison analysis, classical content analysis) and 1 quantitative analysis (i.e., correspondence analysis). The 2 qualitative analyses revealed the following 3 metathemes: adjustment (how these doctoral students made necessary accommodations with regard to all aspects of their lives), which comprised the themes of time management, interaction, belief, and lifestyle; encouragement (circumstances that motivated them to pursue their doctoral degrees), which comprised the themes of intrinsic motivation and extrinsic motivation; and discouragement (circumstances that demotivated them from pursuing their doctoral degrees), which comprised the themes of internal discouragement and external discouragement. The correspondence analysis revealed a fourth metatheme, namely, marital status (separating the single students from the married/divorced students), which comprised the themes of locus of motivation and locus of discouragement. Seven of these women doctoral students struggled to balance either dual roles (i.e., as doctoral students and wives/mothers, or as doctoral students and professionals) or triple roles (i.e., as doctoral students, wives/mothers, and professionals). Implications of the findings are discussed.
Anchoring Identity in Faith: Narrative of an Anglo-Asian Muslimah in Britain
Authors: Mogra Imran
Published: March 2021

This article is based on a narrative of an Anglo-Asian Muslimah, studying in a prominent university in the city of Birmingham, England. The trainee teacher was a suitable candidate for my research for the additional characteristics, which she had. She was born as a Muslimah in England, she was neither totally Asian nor English in reality; she was the daughter of a Pakistani mother and an English father. Using narrative analysis, several key themes, such as family, friendship, and cultural practices, emerged. These themes shed light about her life experiences. Significantly, she reveals the important influence of Islam and faith as the core of her identity, which is apparently used as a mechanism in contemporary society. In conclusion, the narrator presents a positive representation of a Muslimah who is at ease with her dual heritage whilst being rooted in Islam. She presents herself as open-minded and undeterred, thus implying that such counter narratives need to be added to the wider Muslim narratives.
Three Adaptations of the Japanese Comic Book Boys Over Flowers in the Asian Cultural Community: Analyzing Fidelity and Modification from the Perspective of Globalization and Glocalization
Authors: Hong Soo
Published: March 2021

A wide variety of cultural products have been adapted into a brand new text in the process of globalization. The three adaptations of the Japanese cartoon, Boys over Flower, in the following countries: Japan, South Korea, and Taiwan have very similar storylines. The three storylines, although similar, have several modifications due to the differing audiences and goals of each series. Based on the idea of globalization; fidelity in the adaptation can be understood as emphasizing the shared values and community spirit between cultures while modifications can be interpreted as organizational gatekeeping. This study analyzes how the narratives in the three adapted texts show fidelity and modification. In conclusion, fidelity could be interpreted as presenting the glocalized cultural values or socio-cultural popular memory in the Asian context while modification could be considered as being reflective of a wide variety of different socio-cultural contexts where the series were created.
