Effects of critical incident tasks on the intercultural competence of English non-majors

ABSTRACT

In this internationalised world, graduate employability in terms of intercultural communication skills needs to be taken into account in higher education. The present study aims to explore the effects of critical incident task instruction on English non-majored undergraduates’ intercultural competence. One group of students received ten weeks of instruction with one critical incident task per week and another group received standard English classes. Data were collected from the students’ pre- and post-test. The results showed a significant and strong effect of the intervention with critical incident tasks. Implications for educational practice are presented for further teaching with critical incident tasks.     

Does “buyer beware” work in migration? Contracting between brokers and migrants in Vietnam

This article is an attempt to open the lid a little of the “black box of migration” i.e. brokers. Analysing contracts between brokers and labour migrants, we identify four different forms of exploitation of migrants by brokers: expropriation of skill premium, risk shifting, over‐charging, and non‐refund of deposits. Opportunistic behaviour by brokers, as evidenced by such exploitation, is seen as a market failure that is explained by human attributes and transactional characteristics. Given the rigidities in the human attributes of the contracting parties and the nature of migration as a risky multi‐period transaction, proposals are made for non‐market interventions, which can lead to more equitable contracting.     

Evaluating Weight of Evidence in the Mystery of Balkan Endemic Nephropathy

Balkan endemic nephropathy (BEN) is a chronic, progressive wasting disease of the kidneys, endemic in certain rural regions of the Balkan nations Croatia, Serbia, Bulgaria, and Romania. It is irreversible and ultimately fatal. Though this disease was first described in the 1950s, its causes have been a mystery and a source of much academic and clinical contention. Possible etiologic agents that have been explored include exposure to metals and metalloids, viruses and bacteria, and the dietary toxins aristolochic acid (AA) and ochratoxin A (OTA). AA is a toxin produced by weeds of the genus Aristolochia, common in Balkan wheat fields. Aristolochia seeds may intermingle with harvested grains and thus inadvertently enter human diets. OTA is a mycotoxin (fungal toxin) common in many foods, including cereal grains. In this study, we analyzed the weight of evidence for each of the suspected causes of BEN using the Bradford Hill criteria (BHC): nine conditions that determine weight of evidence for a causal relationship between an agent and a disease. Each agent postulated to cause BEN was evaluated using the nine criteria, and for each criterion was given a rating based on the strength of the association between exposure to the substance and BEN. From the overall available scientific evidence for each of these suspected risk factors, AA is the agent with the greatest weight of evidence in causing BEN. We describe other methods for testing causality from epidemiological studies, which support this conclusion of AA causing BEN.     

First hitting time of integral diffusions and applications

We study the first hitting time of integral functionals of time-homogeneous diffusions, and characterize their Laplace transforms through a stochastic time change. We obtain explicit expressions of the Laplace transforms for the geometric Brownian motion (GBM) and the mean-reverting GBM process. We also introduce a novel probability identity based on an independent exponential randomization and obtain explicit Laplace transforms of the price of arithmetic Asian options and other derivative prices that non-linearly depend on the integral diffusions. Numerical examples are given to demonstrate the accuracy and efficiency of the proposed method.     

Flood risk mapping and analysis using an integrated framework of machine learning models and analytic hierarchy process

In this study, a new approach of machine learning (ML) models integrated with the analytic hierarchy process (AHP) method was proposed to develop a holistic flood risk assessment map. Flood susceptibility maps were created using ML techniques. AHP was utilized to combine flood vulnerability and exposure criteria. We selected Quang Binh province of Vietnam as a case study and collected available data, including 696 flooding locations of historical flooding events in 2007, 2010, 2016, and 2020; and flood influencing factors of elevation, slope, curvature, flow direction, flow accumulation, distance from river, river density, land cover, geology, and rainfall. These data were used to construct training and testing datasets. The susceptibility models were validated and compared using statistical techniques. An integrated flood risk assessment framework was proposed to incorporate flood hazard (flood susceptibility), flood exposure (distance from river, land use, population density, and rainfall), and flood vulnerability (poverty rate, number of freshwater stations, road density, number of schools, and healthcare facilities). Model validation suggested that deep learning has the best performance of AUC = 0.984 compared with other ensemble models of MultiBoostAB Ensemble (0.958), Random SubSpace Ensemble (0.962), and credal decision tree (AUC = 0.918). The final flood risk map shows 5075 ha (0.63%) in extremely high risk, 47,955 ha (5.95%) in high-risk, 40,460 ha (5.02%) in medium risk, 431,908 ha (53.55%) in low risk areas, and 281,127 ha (34.86%) in very low risk. The present study highlights that the integration of ML models and AHP is a promising framework for mapping flood risks in flood-prone areas.     

“She Is Not Acting,She Is”

This essay examines the popular television show RuPaul's Drag Race to reveal the ways drag performance provides an ambivalent, contradictory space for wrestling with contentious issues surrounding cultural identity and authenticity in reality TV. Focusing on the show's controversial season three, the authors demonstrate how drag queens subvert and play with ideas of gender “realness” but find an impasse in open discussions of race. The racial minstrelsy of some contestants we observe created antagonisms between black/brown characters and their white/Asian counterparts, exposing a rift in ideas about racial play despite the general acceptance of flexibility in gender bending. Recognizing that reality TV exploits and uncovers these tensions, we demonstrate that while drag performance enacts a subversive mode of queer performance, it provides a contested site and complex semiotic space for dealing with sensitive matters of race/ethnicity, especially when certain forms of stereotyping are rewarded over others.     

The commonalities and differences in health professionals’ views on home birth in Tasmania,Australia: A qualitative study

ObjectivesHome birth has attracted great controversy in the current context. There is a need for the public and health professionals to understand why maternity care providers have such different views on home birth, why they debate, what divides them into two opposite sides and if they have anything in common.MethodA qualitative study involving twenty maternity health providers in Tasmania was conducted. It used semi-structured interview which included closed and open-ended questions to provide opportunities for exploring emerging insights from the voices of the participants.FindingsHealth practitioners who support home birth do so for three reasons. Firstly, women have the right to choose the place of birth. Secondly, home birth may be more cost effective compared to hospital birth. Thirdly, if home birth is not supported, some women might choose to have a free birth. Those who opposed home birth argue that complications could occur at childbirth and the transfer time is critical for women's and babies’ safety. These differences in opinions can be due to the differences in the training and philosophy of the maternity care providers. Despite the differing views on home births, health professionals share a common goal to protect the women and the newborns from unexpected situations during childbirth.ConclusionThis article provides some significant insights derived from the study of home birth from the maternity health professionals’ perspectives and could contribute to the enhancement of mutual understanding and collaboration of health professionals in their services to expectant mothers.     

The Effects of Sociocultural Factors on Older Asian Americans' Access to Care

Most Asian American elders are immigrants to the United States, and sociocultural factors such as English proficiency and immigration status are prominent factors in their lives. Using data from the California Health Interview Surveys to focus on Asian Americans over age 50, this study seeks to identify interethnic differences, and the effects of English proficiency and immigration status in the way older Asian Americans access healthcare. The results indicated that Asian ethnicity, English proficiency, and immigration status have significant independent effects on older Asian Americans' access to care. Implications for social work's role in addressing access disparities are discussed.     

Robust Inference for the Bivariate Bifurcating Autoregressive Model

Cell lineage data consist of observations on quantitative characteristics of the descendants of an initial cell, recorded as a tree so that the relationships between the cells may be determined. The bifurcating autoregressive model of Cowan & Staudte (1986) has been used previously to model univariate characteristics of cell linkage data. Here we extend this model to analyze bivariate cell data. Both maximum likelihood and robust estimators are derived for both balanced and unbalanced cell lineage trees and are applied to a real dataset to estimate the correlation between cell lifetime and final cell diameter.     

Women's maternity care needs and related service models in rural areas: A comprehensive systematic review of qualitative evidence

BackgroundUnderstanding the needs of rural women in maternity care and service models available to them is significant for the development of effective policies and the sustainability of rural communities. Nevertheless, no systematic review of studies addressing these needs has been conducted.ObjectivesTo synthesise the best available evidence on the experiences of women's needs in maternity care and existing service models in rural areas.MethodsLiterature search of ten electronic databases, digital theses, and reference lists of relevant studies applying inclusion/exclusion criteria was conducted. Selected papers were assessed using standardised critical appraisal instruments from JBI-QARI. Data extracted from these studies were synthesised using thematic synthesis.Findings12 studies met the inclusion criteria. There were three main themes and several sub-themes identified. A comprehensive set of the maternity care expectations of rural women was reported in this review including safety (7), continuity of care (6) and quality of care (6), and informed choices needs (4). In addition, challenges in accessing maternity services also emerged from the literature such as access (6), risk of travelling (9) and associated cost of travel (9). Four models of maternity care examined in the literature were medically led care (5), GP-led care (4), midwifery-led care (7) and home birth (6).ConclusionThe systematic review demonstrates the importance of including well-conducted qualitative studies in informing the development of evidence-based policies to address women's maternity care needs and inform service models. Synthesising the findings from qualitative studies offers important insight for informing effective public health policy.
