Abstract
The discovery of the electromagnetic counterpart to the binary neutron star (NS) merger GW170817 has opened the era of gravitational-wave multimessenger astronomy. Rapid identification of the optical/infrared kilonova enabled a precise localization of the source, which paved the way to deep multiwavelength follow-up and its myriad of related science results. Fully exploiting this new territory of exploration requires the acquisition of electromagnetic data from samples of NS mergers and other gravitational-wave sources. After GW170817, the frontier is now to map the diversity of kilonova properties and provide more stringent constraints on the Hubble constant, and enable new tests of fundamental physics. The Vera C. Rubin Observatory’s Legacy Survey of Space and Time can play a key role in this field in the 2020s, when an improved network of gravitational-wave detectors is expected to reach a sensitivity that will enable the discovery of a high rate of merger events involving NSs (∼tens per year) out to distances of several hundred megaparsecs. We design comprehensive target-of-opportunity observing strategies for follow-up of gravitational-wave triggers that will make the Rubin Observatory the premier instrument for discovery and early characterization of NS and other compact-object mergers, and yet unknown classes of gravitational-wave events.
Biogeographic assessment of Gorgonian associated bacteria with antipathogenic Urinary Tract Infections (UTIs) in Karimunjawa Marine National Park, Java Sea, Indonesia
Authors: Sabdono Agus , Lestari Endang Sri , Sibero Mada T. 
Published: May 2022

Gorgonian corals of Karimunjawa are impacted by anthropogenic activities, such as increasing high mariculture intensity with consequent eutrophication, overfishing, tourism, sewage, and other pollutant discharge, which result in changes in the microbial community structure. In this study, bacterial communities associated with six species of gorgonian, Viminella sp., Ellisella sp., Antipathes sp., Melithaea sp., Astrogorgia sp, and Junceella sp. from both the Marine Protected Area (MPA) and non-Marine Protected Area (non-MPA) zones were screened for their antipathogenic potential against Urinary Tract Infections (UTIs) pathogens. The selected bacterial isolates were identified and compared for their abundance and diversity between the two zones. 156 bacterial strains were assayed for their prospective antipathogenic compounds against seven UTI pathogens, including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptococcus saptophyticus, Acinetobacter baumannii, Klebsiella pneumonia, Candida albicans. The result showed that 17 of 92 (18.48%) and 6 of 64 (9.37 %) bacterial isolates from MPA and non-MPA, respectively, exhibited antimicrobial activity in at least one UTIs pathogens. Analyzing the gene of 16S rRNA discovered that the 17 isolates of MPA were associated with phyla Actinobacteria, Firmicutes, and Proteobacteria, including Streptomyces zhaozhoue, Nocardiopsis salina, Micrococcus endophyticus, Brevibacterium casei, Micrococcus yunnanensis, Saccharopolyspora coralli, Bacillus paramycoides, Virgibacillus salarius, Oceanobacillus iheyensis, Vibrio alginolyticus. In contrast, only six selected isolates of non-MPA were associated with phyla Actinobacteria and Proteobacteria, including Nocardiopsis salina, Micrococcus yunnanensis, and Acinetobacter soli. The diversity index (H'), species richness (S), and relative abundance of the MPA zone were higher than that of non-MPA. These results demonstrated that gorgonian octocoral species in the MPA region harbor varied bacteria and propose that many gorgonian-associated bacteria have the prospective for advancing broad-spectrum antibiotics.
Éditorial : Nouvelles questions ethniques
Authors: Raulin Anne , Crenn Chantal 
Published: May 2022

La question ethnique a toujours été polémique. Dans les années 1980, certains anthropologues ont estimé devoir s’en détourner afin de créer une rupture avec des représentations perçues comme liées à la colonisation. Dans les dernières décennies, nombre de chercheurs ont complexifié son approche théorique, et il importe de faire le point en relation avec les nouvelles conditions historiques, postcoloniales et postsocialistes, la généralisation du marché mondial et celle de la circulation des personnes et des biens, ainsi qu’avec le renforcement du phénomène diasporique. Les contributions à ce dossier montrent que, loin de s’apparenter à un archaïsme, les appartenances ethniques manifestent une réelle capacité d’adaptation dans un contexte toujours dominé par les entités nationales. L’identification ethnique, une des modalités de la perception de l’altérité, ne saurait cependant être limitée aux minorités. Ce dossier donne à connaître les points de vue de l’intérieur de ces appartenances à partir de terrains ethnographiques diversifiés : migrations entre Sénégal et France, marchandisation du « mariage marocain », pratique d’un islam mahorais, diaspora asiatique à Paris, soins ethnicisés à l’hôpital. Il apporte aussi de nouvelles approches théoriques en ouvrant la « situation ethnique » aux dynamiques de globalisation, ou en la différenciant des problématiques liées au racisme et aux discriminations
Quatre demoiselles d’Avignon : marchandisation du « mariage marocain » en Europe et fin du sujet ethnique
Authors: Affaya Rim 
Published: May 2022

Comment les rituels du pays d’origine se transforment en marchandise ? Cet article entend réfléchir aux liens entre appartenance, consommation et fabrique de l’entrepreneur·e en problématisant le recours aux catégories ethniques en sciences sociales. Plus précisément, il montre comment la relégation sociale et urbaine des descendant·e·s d’immigré·e·s — d’origine marocaine en France — peut servir de levier pour une ascension socioéconomique à travers les économies festives. Par le biais d’une enquête ethnographique à Avignon, l’article examine de nouvelles figures du travail autonome dans le monde du « mariage marocain » en France et rattache les stratégies de profitabilité propres au capitalisme à divers « arrangements » avec les esthétismes de la culture d’origine. L’article se conclut sur une critique du paradigme de l’ethnicité en faisant valoir l’importance des études des styles de vie pour comprendre comment ceux-ci marquent les sociétés européennes postmigratoires.
Le rôle de l’ethnicité dans les associations culturelles de migrants. Le cas des Sereer (Sénégal) de Dakar et d’Île-de-France
Authors: Ndour Rébecca 
Published: May 2022

Croyance subjective en des origines communes dans de nombreuses parties du monde, l’ethnicité suscite souvent chez ceux qui s’en réclament comme chez ceux qui la rejettent l’idée d’une totalité d’être. Avec les migrations, comment est-ce que cette croyance se perpétue à travers le temps et les espaces ? Cet article traite de cette question à travers l’exemple d’associations de migrants Sereer à Dakar et en Île-de-France rencontrées entre 2012 et 2014. L’observation montre que les associations de migrants, en quête d’intégration sociale dans leurs nouvelles zones d’installation, mobilisent la même ethnicité, mais en s’arrangeant avec les exigences de leur cadre national et les propriétés sociales des membres associatifs, pour valoriser des éléments de l’ethnicité en cohérence avec l’objectif d’intégration sociale. Rendue saillante ou voilée, l’ethnicité se révèle une dimension parmi d’autres de l’expérience sociale, dépendante d’elle et la transformant en même temps.

Authors: Juneja Richa , Pati Haraprasad , Gupta Gopila , Mahapatra Manoranjan , Tyagi Seema , Saxena Renu 
Published: May 2022

Background
Monoclonal protein detection and characterization is integral component of myeloma workup and is at times used as the first step toward diagnosis. Costs of these tests are major concern in developing countries.
Recent studies have emphasized on the prognostic importance of risk stratification with cytogenetic in patients with myeloma.

Aims
We intend to analyze additional information obtained by two costly tests, namely, serum free light chain assay (sFLC) and fluorescent in situ hybridization (FISH), for high-risk cytogenetic abnormalities during baseline workup of patients with myeloma and their necessity.

Patients and methods
We retrospectively analyzed laboratory data of 130 patients with myeloma enrolled at our institute between years 2016 and 2019. Subset analyses of 71 patients who underwent all three tests, namely, serum protein electrophoresis (SPEP), immunofixation electrophoresis (IFE), and sFLC for monoclonal protein detection, were done.
Patterns of cytogenetic abnormalities were noted in 70 patients undergoing FISH testing for high-risk cytogenetic abnormalities and serum lactate dehydrogenase (LDH) level. International staging system (ISS) and revised international staging system (RISS) categories were compared among this group of patients.

Statistical analysis used
A proportion test was used.

Results
SPEP detected and quantified M protein in 55 (77.4%) patients. IFE detected M protein in 68 (95.7%) patients and typing was done. sFLC ratio was abnormal in 66 (92.6%) patients. IFE and sFLC were more sensitive in detecting monoclonal protein as compared with SPEP (P=0.001 and 0.009, respectively) at diagnosis.
In 70 patients with FISH and LDH results available, seven (10%) patients had high-risk karyotype on FISH, and LDH was raised in five (7.1%). Based on these results, three (4.2%) patients who were ISS stage I were upgraded to RISS stage II and 21 (30%) ISS III patients were downgraded to RISS II category, thereby helping in 34.2% patients for accurate prognostication.

Conclusion
In resource-constrained setting, using sFLC sequentially after SPEP is noninformative, but UPEP/IFE shows M band, which can be a viable approach at diagnosis. For better prognostication, FISH for high-risk karyotypic abnormalities is required.

Authors: Faruk Jamilu A. , Adebiyi Niyi M. , Ahmad Hafsat R. 
Published: May 2022

Context
Acute leukemia (AL) is the commonest hematological malignancy in childhood. The cause is largely multifactorial and unknown, with exogenous and endogenous factors interacting with genetic susceptibility. Its incidence is on the rise globally including developing countries like Nigeria. Although the prognosis in developed countries has improved, poor outcomes are still the norm in resource-poor areas.

Aims
This review was undertaken to document the sociodemographic characteristics, management challenges, and outcomes of leukemia in an African tertiary care setting.

Settings and design
The study was a retrospective review of patients managed for AL over a 30-month period.

Patients and methods
This is a retrospective review of clinical case notes of children admitted with diagnosis of AL.

Results
A total of 31 children had morphological diagnosis of AL; half of them had acute lymphoblastic leukemia, a third acute myeloid leukemia, and one-sixth bilineal leukemia, respectively. Most patients were from low socioeconomic status. All patients sought alternative or complimentary care, and source of health care expenditure was out of pocket. The mean duration of symptoms was 12.9±10.3, time to diagnosis in our hospital was 3.7±2.1 days, and duration of hospital stay was 36.7±43.4 days. The mean packed cell volume, white blood cell, and platelet counts were 14.2±5.3, 37.9±30.2×109/l, and 45.4±54.3×109/l, respectively. Only four patients attained remission of the 15 (48.4%) who received chemotherapy. The mortality was 11 (35.5%) cases, with eight cases being owing to hemorrhage from severe thrombocytopenia.

Conclusions
The study shows delay in time from symptoms to presentation, time to diagnosis, and commencement of chemotherapy with associated poor outcomes. All patients sought alternative and/or complementary interventions before presentation.

BACKGROUND:
Workplace bullying (WPB) is any sort of repeated and unjustified verbal, sexual, or physical intimidation that a person is exposed to by a group or another person in the workplace. In healthcare environments, practitioners are occasionally victims of WPB incidents. Bullying in surgical environments is an important issue that needs attention as it could affect patient care either directly or indirectly. The objective of this study was to assess the prevalence of bullying in surgical environments in multiple regions in Saudi Arabia.

MATERIALS AND METHODS:
This cross-sectional study was conducted among surgeons, trainees, interns, nurses, and students in surgical specialties in multiple Saudi regions. The survey was designed by Survey Monkey and posted online. The data were analyzed through SPSS Version-21 by computing descriptive statistics as frequency and percentages with graph construction.

RESULTS:
About two-thirds (65.2%) of the 788 study participants were male and were between the age of 20 and 29 years (67.8%). Consultants came first as perpetrators of bullying in the past 12 months (44.3%) and residents and interns were the major victims. The NAQ-R score ranged from 22.00 to 110.00, with a mean score of 42.47 (SD=17.9). Statistically significant association was found between mean NAQ-R score and age (P = 0.007), specialty (P = 0.002), and position (P < 0.001).

CONCLUSION:
WPB is a pervasive problem in surgical environments in multiple regions of Saudi Arabia. Consultants and specialists are the primary offenders in bullying, which makes the hospital an environment for bullying behaviors.

Published: May 2022

BACKGROUND:
Video games have become popular in the last few decades, resulting in an increase in reported negative consequences. This study aimed to assess the prevalence of internet gaming disorder (IGD), its association with gaming behavior, depression, and anxiety in male high school students.

MATERIALS AND METHODS:
This cross-sectional study involved male high school students in Dammam. Schools were selected using stratified random sampling, and data were collected using a self-administered questionnaire. Data analyzed using SPSS v23.0; the initial analysis included descriptive statistics. Continuous and ordinal variables were compared using t-test or Mann–Whitney U test, and ANOVA or Kruskal–Wallis test, as appropriate; Chi-square test was used for categorical variables. Spearman correlation coefficient was calculated to determine the correlation between IGD score and depression and anxiety scores.

RESULTS:
A total of 726 high school gamers were involved, 87% of whom were Saudi, with a mean age of 16.92 years and 45% were from public schools. The mean IGD score was 18.12, and the prevalence of IGD was 21.85%. Students who spent ≥4 h/day on weekdays or ≥6 h/day at weekends on videogames and gamers who spent ≥200 Saudi Riyals per month on gaming had significantly higher mean IGD scores (P < 0.001). Gamers who used PC/laptop for gaming had significantly higher IGD scores compared to those who used other devices (P = 0.002). Action, fight, open-world games, and games with violence were associated with significantly higher IGD scores. Among students with IGD, 21.7% had moderately severe/severe depression and 11.4% had severe anxiety.

CONCLUSION:
IGD is a concerning psychiatric disorder in male high school students. It is associated with certain gaming behavior and other mental problems. We recommend future larger-scale research that includes females as well.

INFORMALITY AND TOTAL FACTOR PRODUCTIVITY IN KENYA
Authors: Opondo Mary , Etyang Martin , Ayieko Onono 
Published: May 2022

Purpose: The Kenyan economy is largely informal. The objective of the study was to establish the effect of size of the informal sector on total factor productivity in the country.
Methodology: The study was based on the dualist theory of the economy. Data covering the period 1974 to 2016 was sourced from government publications (Economic Surveys and Statistical Abstracts), the Global Financial Development Database and the World Development Indicators. A growth accounting exercise was conducted using the Cobb-Douglas production function based on the Solow growth model. This enabled the decomposition of output growth to the contributions of labour and capital with a residual, commonly referred to as the total factor productivity which was the dependent variable in the study. The study was non-experimental and utilized a longitudinal research design using macro-level data thus limiting the possibility of data manipulation. Various theoretically and empirically recognized determinants on TFP were included as control variables. The analysis was conducted using ordinary least squares.
Findings: The findings show that the size of the informal sector has a negative and statistically significant effect on total factor productivity in Kenya. Given the large informal sector, the study concluded that there is need to increase productivity of the sector in the country for improved economic performance.
Unique contribution to theory, practice and policy: From the study findings, the informal sector has a negative and statistically significant effect on total factor productivity in Kenya. The study recommends the development and implementation of policies to enhance productivity in the sector. These include market and technological development, improved infrastructure and access to credit facilities.
