“It’s better I’m dead”: oppression and suicidal ideation
Authors: Reber Lisa 
Published: July 2021

Purpose
Anecdotal accounts of suicide among temporary low-wage migrant workers in the UAE are numerous, but unofficial and qualitative accounts remain unexplored. This study aims to examine how the socio-environmental context can lead some low-wage migrants, irrespective of their nationality or culture, to contemplate suicide for the first time after arriving in the host country.

Design/methodology/approach
The findings draw from ten months of qualitative fieldwork (2015–2016) and in-depth interviews conducted with 44 temporary migrant workers from sub-Saharan Africa and South Asia, earning in the lowest wage bracket in Dubai. The study used a non-probabilistic, purposive sampling approach to select participants. Three criteria drove eligibility: participants had to reside in the UAE, be non-national and earn Dh1500 (US$408) or less a month. Otherwise, diversity was sought in regard to nationality, occupation and employer.

Findings
Eight (18%) of the 44 study participants interviewed admitted to engaging in suicidal thoughts for the first time after arriving in the UAE. The findings suggest that for low-wage migrants working in certain socio-environmental contexts, the religious, gendered or other cultural or group characteristics or patterns that may be predictors of suicide in migrants’ country of origin may become secondary or possibly even irrelevant when one is forced to survive under conditions that by most objective standards would be deemed not only oppressive but extremely exploitative and abusive.

Originality/value
This study contributes to understandings of how the emotional and psychological well-being of temporary foreign low-wage migrant workers can be impacted by the socio-environmental context of the host country. It is a first step in understanding the intimate thoughts of low-wage migrant workers on the topic of suicidality, furthering our understanding of suicidal ideation and the factors that can contribute to it.
Exploring the interplay between question-answering systems and communication with instructors in facilitating learning
Authors: Yi Cheng , Zhu Runge , Wang Qi 
Published: July 2021

PurposeQuestion-answering (QA) systems are being increasingly applied in learning contexts. However, the authors’ understanding of the relationship between such tools and traditional QA channels remains limited. Focusing on question-answering learning activities, the current research investigates the effect of QA systems on students' learning processes and outcomes, as well as the interplay between two QA channels, that is, QA systems and communication with instructors.Design/methodology/approachThe authors designed and implemented a QA system for two university courses, and collected data from questionnaires and system logs that recorded the interaction between students and the system throughout a semester.FindingsThe results show that using a QA system alone does not improve students' learning processes or outcomes. However, the use of a QA system significantly improves the positive effect of instructor communication.Originality/valueThis study contributes to the literature on learning and education technology, and provides practical guidance on how to incorporate QA tools in learning.
Foreign capital inflows and economic growth: the experience of low-income countries in Sub Saharan Africa
Authors: Awad Atif 
Published: July 2021

Purpose
This paper aims to investigate the long-run impact of selected foreign capital inflows, including aid, remittances, foreign direct investment (FDI), trade and debt, on the economic growth of 21 low-income countries in the Sub Saharan Africa (SSA) region, during the period 1990–2018.

Design/methodology/approach
To obtain this objective and for robust analysis, a parametric approach, which was dynamic ordinary least squares, and a non-parametric technique, which was fully modified ordinary least squares, were used.

Findings
The results of both models confirmed that, in the long run, trade and aid affected the growth rate of the per capita income in these countries in a positive way. However, external debt seemed to have an adverse influence on such growth.

Originality/value
First, this is the initial study that has addressed this matter across a homogenous group of countries in the SSA region. Second, while most of the previous studies regarding capital inflows into the SSA region have focused on the impact of only one or two aspects of such foreign capital inflows on growth, the present study, instead, examined the impact of five types of foreign capital inflows (aid, remittances, FDI, trade and debt).

Published: July 2021

Purpose
Rwanda established a deinstitutionalization program to end institutional care and transition to family-based care for children. Part of their program involved training local volunteers in an evidence-based, trauma-informed caregiving model, Trust-Based Relational Intervention (TBRI), to provide education, support and TBRI training to caregivers who reunited or adopted children from institutional care in Rwanda. This study aims to describe the process of disseminating a trauma-informed intervention, TBRI, as part of the national deinstitutionalization program in Rwanda.

Design/methodology/approach
Semi-structured interviews were conducted with ten lay social workers about Rwanda’s care reform and their experience using TBRI. A phenomenological approach was used to qualitatively analyze the interviews.

Findings
Analysis revealed five themes centered on the usefulness and universality of TBRI, the power of community in meeting the needs of children and youth and the importance of connection in supporting children who have experienced institutional care.

Originality/value
A global call to end institutional care and shift to family-based care for children has organizations, governments and experts seeking pathways to implement care reform. Although care reform is a complex process, Rwanda created and implemented a deinstitutionalization program focused on spreading the message of care reform and providing sustainable support for caregivers and families.
Machine learning using synthetic images for detecting dust emissions on construction sites
Authors: Xiong Ruoxin , Tang Pingbo 
Published: July 2021

PurposeAutomated dust monitoring in workplaces helps provide timely alerts to over-exposed workers and effective mitigation measures for proactive dust control. However, the cluttered nature of construction sites poses a practical challenge to obtain enough high-quality images in the real world. The study aims to establish a framework that overcomes the challenges of lacking sufficient imagery data (“data-hungry problem”) for training computer vision algorithms to monitor construction dust.Design/methodology/approachThis study develops a synthetic image generation method that incorporates virtual environments of construction dust for producing training samples. Three state-of-the-art object detection algorithms, including Faster-RCNN, you only look once (YOLO) and single shot detection (SSD), are trained using solely synthetic images. Finally, this research provides a comparative analysis of object detection algorithms for real-world dust monitoring regarding the accuracy and computational efficiency.FindingsThis study creates a construction dust emission (CDE) dataset consisting of 3,860 synthetic dust images as the training dataset and 1,015 real-world images as the testing dataset. The YOLO-v3 model achieves the best performance with a 0.93 F1 score and 31.44 fps among all three object detection models. The experimental results indicate that training dust detection algorithms with only synthetic images can achieve acceptable performance on real-world images.Originality/valueThis study provides insights into two questions: (1) how synthetic images could help train dust detection models to overcome data-hungry problems and (2) how well state-of-the-art deep learning algorithms can detect nonrigid construction dust.

Published: July 2021

Purpose
This study aims to analyse the effectiveness of a static promotional banner located on a hotel reservation website in terms of capturing the visitor’s visual attention by exploring how this impact depends on the user’s degree of internet experience.

Design/methodology/approach
An experiment was conducted using the eye-tracking methodology, in addition to a self-administered questionnaire. Through eye-tracking technology, eye movements were recorded whilst participants explored a generic hotel website. The factors used in the analyses were the position of the banner on the website and participants’ experience as internet users.

Findings
The findings showed that positioning a banner at certain locations on the webpage may lead to a better recall, which, in part, seems to result from the visual attention that such locations attract. The mediation analysis showed that the bottom-right and bottom-left positions have a negative effect on banner recall due, in part, to the shorter attention times and the smaller number of fixations those positions induce. Although the visitor’s level of internet experience affected his/her visual attention towards the banner, its impact on banner recall was non-significant. Results are discussed considering which variables produce greater effectiveness in capturing the user’s attention.

Practical implications
The paper draws several implications for the marketing literature, hospitality management and society in general.

Originality/value
The study is the first to analyse the impact of the position of a static ad on users’ visual attention and memory, considering the user’s degree of internet experience.

Published: July 2021

AbstractPseudomonas aeruginosa is a Gram‐negative opportunistic pathogen that presents a serious risk to immunosuppressed individuals and other extremely vulnerable patients such as those in intensive care units. The emergence of multidrug‐resistant Pseudomonas strains has increased the need for new antipseudomonal agents. In this study, a series of amino group‐modified aminopenicillin derivatives was synthesized that have different numbers of carboxyl groups and structurally resemble carboxypenicillin–ureidopenicillin hybrids, and their antipseudomonal activities were evaluated. Among the derivatives synthesized, diethylenetriaminepentaacetic acid (DTPA)‐modified amoxicillin (DTPA‐Amox) showed potent antipseudomonal activity, not only against the laboratory strain PAO1 but also against clinically isolated Pseudomonas strains that were resistant to piperacillin and carbenicillin. DTPA‐Amox had no obvious cytotoxic effects on cultured mammalian cells. In addition, in an in vivo model of leukopenia, DTPA‐Amox treatment produced a moderate but statistically significant improvement in the survival of mice with P. aeruginosa strain PAO1 infection. These data suggest that polycarboxylation by DTPA conjugation is an effective approach to enhance antipseudomonal activity of aminopenicillins.
Nonskeletal injuries related to cardiopulmonary resuscitation: An autopsy study
Authors: Righi Fabiola A. , Jenkins Sarah , Lin Peter T. 
Published: July 2021

AbstractThe current standard technique for cardiopulmonary resuscitation (CPR), initially described in the early 1960s, has quickly become the expected response for all persons found without a pulse or respiration. Despite the potentially lifesaving properties of external cardiac massage, the mainstay of resuscitation, it consists of repeated blunt force trauma to the chest, which can lead to extensive traumatic skeletal and nonskeletal injuries. Numerous autopsy‐based studies have documented the incidence and patterns of rib and sternal fractures associated with attempted CPR, but there is relatively little data on the incidence and severity of nonskeletal CPR‐related injuries. We reviewed reports from 1878 autopsies performed between September 2017 and December 2019 (inclusive), for documentation of CPR‐related injuries. Among these cases, there were 93 cases with resuscitation‐related nonskeletal injuries. The most common type of injury identified were visceral contusions, documented in 57.0% of cases. These contusions predominantly involved the heart, lungs, neck soft tissue, and surrounding structures. Resuscitation‐related lacerations were seen in 17.2% of the cases, most predominantly involving the pericardium, heart, and liver. Statistical analysis of the data demonstrated that lacerations were more likely to be seen in females and with associated sternal fractures. Additionally, hemothoraces were present in 34.4% of cases and hemopericardium was seen in 8.6% of cases. This study provides additional documentation of the range, severity, and incidence of various types of resuscitation‐related visceral injuries to better assist autopsy pathologists in distinguishing these injuries from other antecedent traumatic injuries.
Curcuma longa enhances IFN‐γ secretion by natural killer cells through cytokines secreted from macrophages

Published: July 2021

AbstractInterferon‐γ (IFN‐γ) regulates the human immune system. To study the interaction between macrophages and natural killer (NK) cells, we established a THP‐1 macrophage‐conditioned media. Among the 58 natural plant extracts tested, Curcuma longa exerted the strongest IFN‐γ‐enhancing effect in NK‐92 cells through THP‐1 macrophages. C. longa extract (CLE) enhanced IFN‐γ secretion 2.3‐ and 4.2‐fold at 50 and 100 µg/ml, respectively. Therefore, we evaluated its IFN‐γ‐enhancing effect in vitro. Although NK‐92 cells did not produce IFN‐γ following treatment with C. longa, enhanced IFN‐γ secretion was observed after treatment with THP‐1 macrophage‐conditioned media. We hypothesized that the cytokines secreted by the CLE‐treated THP‐1 macrophages are responsible for stimulating NK‐92 cells. Cytokine array results show upregulation of cytokines, including MIP‐1α, CXCL‐1, IL‐1β, PAI‐1, and TNF‐α, in CLE‐treated THP‐1 macrophages. To determine the cytokines responsible for augmenting IFN‐γ secretion, NK‐92 cells were stimulated with MIP‐1α, CXCL‐1, IL‐1β, or PAI‐1. Enzyme‐linked immunosorbent assay results show that all cytokines induced IFN‐γ production, although the dose response was somewhat varied. High‐performance liquid chromatography analysis of CLE revealed the concentrations of three active curcuminoids, curcumin, demethoxycurcumin, and bisdemethoxycurcumin, as 6.70%, 1.00%, and 0.95%, respectively. Their mixture (with concentrations comparable to their occurrence in CLE) exerted an effect similar to that of the whole CLE. Our findings reveal that CLE indirectly stimulated NK‐92 cells to secrete IFN‐γ, which is mediated by cytokines produced from THP‐1 macrophages. Further, we identified three curcuminoids partly responsible for this IFN‐γ‐enhancing effect. Therefore, C. longa can be used as a functional food ingredient owing to its immune‐boosting ability.Practical ApplicationThis study demonstrates that CLE stimulates THP‐1 macrophages to secrete cytokines, which can in turn stimulate IFN‐γ production by NK‐92 cells. A mixture of three curcuminoids present in the extract exerted effects similar to whole CLE, demonstrating that the curcuminoids are partly responsible for the IFN‐γ‐enhancing effect of C. longa. Since IFN‐γ is a key regulator of human immune system, these results suggest the potential use of C. longa as an immune‐boosting functional food ingredient.

Published: July 2021

AbstractWhite tea has been of increasing public interest worldwide owing to its health benefits. Based on 2 years of surveillance, the long‐term and cumulative chronic exposure risks of pesticide residues through white tea drinking were assessed for different subpopulations in Fujian, China. Twenty‐five different pesticides were found, and 74.8% of samples contained at least one pesticide residue. The most frequently detected pesticide was bifenthrin with detection rates of 61.6%. Risk assessment was performed using both the deterministic approach and semiprobabilistic model under the best‐case and the worst‐case scenarios. The results demonstrated that the dietary risks were extremely low for six different subpopulations in which the risks for adults over the age of 41 were relatively higher. The risk ranking scheme indicated that isocarbophos and triazophos were considered to be of medium risk. The different use suggestions for the 25 positive pesticides are proposed to further minimize the exposure risk to consumer health.Practical ApplicationTea is the second most popular nonalcoholic beverage throughout the world. Pesticides are used to improve the yield of tea. Pesticide residues in tea could be one of the exposure pathways for consumers. Monitoring residual levels and assessing the health risk assessment in tea are thus in an urge.
The use of case studies in developing students’ understanding of the concept ‘material misstatement’
Authors: Agrawal Prerana , Birt Jacqueline , Bayne Lyndie , Schonfeldt Nikki 
Published: July 2021

AbstractWe investigate the use of an audit case study in developing students’ understanding of the key concept ‘material misstatement’. Using semantic differentials, we explore changes in connotative meaning (reflecting emotional reaction) of undergraduate students at an Australian university. Shifts in class perspective indicate students perceive the concept as more useful and less fluid after the case study. We contribute to the audit education literature by focusing on this complex concept and developing teaching methodologies to enhance students’ learning. Results support inclusion of comprehensive case studies embedded with judgement and decision making, in accounting curricula to enhance understanding of complex concepts.
Captivity, Kinship, and Black Masculine Care Work under Domestic Warfare
Authors: Burton Orisanmi 
Published: July 2021

ABSTRACTThis article examines the forms of intergenerational kinship and care work that Black men perform within and beyond US prisons. First, I offer a historical conceptualization of domestic warfare as a multilayered process that targets Black radical activism, social/familial life, and the interiority of Black subjectivity. I argue that the rupturing of intimacy and familial relationships precipitated by the prison should be understood not as an incidental byproduct of a poorly designed carceral regime but as a tactic of war and a condition of genocide. Next, I theorize letter writing as an ethnographic and political modality that is part of a broader repertoire of strategies that Black men deploy to survive within and rebel against domestic war. I then draw on correspondence between myself and Absolute, an imprisoned Black man, as well as oral histories I collected with elders of New York's radical prison movement, to show how Black men care for each other, forge kinship networks, and transmit knowledge. I close by showing how Absolute carries on traditions of knowledge production and care to younger generations of captive Black men and by connecting this intergenerational practice to forms of collective rebellion.

A principled approach to cross‐sector genomic data access
Authors: Smith Marcus , Miller Seumas 
Published: July 2021

AbstractGenomic data is growing in importance as scientific knowledge and technology develop, and in availability, as direct‐to‐consumer genomic health testing and recreational genealogy services become more widely utilized. Access to genomic data needs to be considered in light of individual privacy. Cross‐sector use of genomic health and ancestry data, and by law enforcement in particular, raises ethical questions and requires appropriate regulation. This article discusses the significance of genomic data and focuses on investigative genetic genealogy, namely the use of genomic health and ancestry data to advance law enforcement, as an example of cross‐sector use. An ethical framework is developed that contributes to a more principled approach to genomic data access.

Background and PurposeHuman pharmacokinetic studies of lung‐targeted drugs are typically limited to measurements of systemic plasma concentrations, which provide no direct information on lung target‐site concentrations. We aimed to evaluate lung pharmacokinetics of commonly prescribed drugs by sampling different lung compartments after inhalation and oral administration.Experimental ApproachHealthy volunteers received single, sequential doses of either inhaled salbutamol, salmeterol and fluticasone propionate (n = 12), or oral salbutamol and propranolol (n = 6). Each participant underwent bronchoscopies and gave breath samples for analysis of particles in exhaled air at two points after drug administration (1 and 6, 2 and 9, 3 and 12, or 4 and 18 h). Lung samples were taken via bronchosorption, bronchial brush, mucosal biopsy and bronchoalveolar lavage during each bronchoscopy. Blood samples were taken during the 24 h after administration. Pharmacokinetic profiles were generated by combining data from multiple individuals, covering all sample timings.Key ResultsPharmacokinetic profiles were obtained for each drug in lung epithelial lining fluid, lung tissue and plasma. Inhalation of salbutamol resulted in approximately 100‐fold higher concentrations in lung than in plasma. Salmeterol and fluticasone concentration ratios in lung versus plasma were higher still. Bronchosorption‐ and bronchoalveolar‐lavage‐generated profiles of inhaled drugs in epithelial lining fluid were comparable. For orally administered drugs, epithelial‐lining‐fluid concentrations were overestimated in bronchoalveolar‐lavage‐generated profiles.Conclusion and ImplicationsCombining pharmacokinetic data derived from several individuals and techniques sampling different lung compartments enabled generation of pharmacokinetic profiles for evaluation of lung targeting after inhaled and oral drug delivery.
