Authors: Chandel N. , Sharma P.
Published: June 2022

Purpose: The paper aims to focus on the question “How can we leverage learning interventions for talent development?” The rise in the need for learning and development for employees has become a priority and a primary reason for job dissatisfaction. Learning and development initiatives are believed to build the required through training campaigns, competencies, and exposure to critical experiences where employees across different bands and streams can be nudged to attend training, enhance their skills, and increase engagement. For an organization to have a learning culture, the most important thing is employee awareness concerning their learning and how their learning is benefiting the business and aligning the individual’s needs to organizational goals. It is usually found that because of time constraints and other factors, employees do not pay much attention to up skill themselves, which calls for a systematic framework to nudge them for inculcating a learning environment. Design/Methodology/Approach - An explorative, qualitative study based on focus groups designed. Findings: Due to time constraints and other factors, employees do not pay much attention to up skill themselves, which calls for a systematic framework to nudge them for inculcating the learning environment. Limitations: Based on the findings, few priority aspects may be crucial to the learning environment. Originality/Value: This paper serves the purpose of explaining the necessity of learning intervention techniques for talent development.

COVID-19 brought the whole world to a halt suddenly and forced it to go on social distancing & lockdown. COVID-19 has impacted every industry worldwide differently and mostly negatively, so we wanted to look at its impact on the ‘esports industry,’ especially in the Indian context. To understand the impact, we did a detailed literature review of academic papers, articles, industry reports to determine the current trend and predict possibility in the future. Our findings indicate that although the industry is facing issues, COVID-19 actually might have helped the esports industry in the long term and expedite its progress among the young generation. Once everything was done, we analyzed the complete literature review, and based on that; we listed out our findings, and based on our findings, we did a final evaluation. We reviewed the existing work of academicians, business reports, industry reports, trends captured by news/media organizations, and the current state of video games to find the trends & reasons which could help us solve our question.

Authors: Saha T. , Bhattacharya S.
Published: June 2022

Organizations continue to be challenged by diversity in their workforce. Hence it becomes imperative to nurture an inclusive workplace where all employees can co-exist and thrive. The primary objective of the current study is to examine the relationship between different constructs of inclusiveness and the organizational commitment of employees. Their search for the study is based on the data collected from multiple IT organizations across major cities (Delhi, Mumbai, Bangalore, and Pune) of India. A structured questionnaire was distributed. Multiple regression analysis was applied on the primary data obtained from 160 respondents to interpret the impact on the organizational commitment by different constructs of inclusiveness. The results from the study reveal that different constructs of inclusiveness (supervisor role, relationship with co-workers, and organizational practices) have a significant effect on the organizational commitment of an employee. The study highlights the importance of creating a sense of acceptance among employees of an organization through inclusive work culture, which ultimately enhances the commitment level of employees towards their organization.
Lipstick color suggested using hybrid hidden Markov model
Authors: Khatreja A. , Mulay P.
Published: June 2022

In today’s lifestyle, facial makeup plays an important role in enhancing visual attractiveness a nd boosting one’s self-esteem. Makeup is known as the second skin of the women, and that too lipstick is a soul of the makeup. According to a survey, an average urban woman spends almost one year and three months of her life just wearing makeup. This much of the time is due to decision-making and choosing the best makeup style that would fit a particular age, skin complexion, profession, and occasion, requiring high imagination and full art. Many makeup recommendations systems exist, but no solitary system has existed to recommend a lipstick color properly to solve this problem computationally. Therefore, as a tiny step towards helping women save their time in decision-making, the proposed model puts forward an idea of a hybrid recommendation model for lipsticks alone. This proposed methodology uses a hidden Markov model to unleash the possible color of the lipsticks based on the given attributes. The collaborative filtering system catalyzes the process to recommend the best lipstick colors using a hybrid recommendation model.
Histopathological analyses of breast cancer using deep learning
Authors: Murthy C.R. , Balaji K.
Published: June 2022

Deep Learning hosts a plethora of variants and models in Convolution Neural Networks (CNN), where the prudence of these methods is algorithmically proven when implemented with sturdy datasets. Much number of haphazard structures and textures are found in the histopathological images of breast cancer, where dealing with such multicolor and multi-structure components in the images is a challenging task. Working with such data in wet labs proves clinically consistent results, but added with the computational models will improvise them empirically. In this paper, we proposed a model to diagnose breast cancer using raw images of breast cancer with different resolutions, irrespective of the structures and textures. The floating image is mapped with the healthy reference image and examined using different statistics such as cross correlations and phase correlations. Experiments are carried out with the aim of establishing the optimal performance on histopathological images. The model attained satisfactory results and are proved good for decision making in cancer diagnosis.

The aim is to evaluate the physiological parameters of the efficacy of cardiac mitochondria transplantation in male mice with chronic neurogenic pain and B16/F10 melanoma growth. Materials and methods. Male mice (n=37) of the C57BL/6 line were used in the research work. The animals covered experimental groups as follows: mice with chronic neurogenic pain (CNP) + B16/F10 melanoma (n=27); mice with CNB + B16/ F10 melanoma + mitochondrial therapy (MC therapy) (n=10). Mitochondria were isolated from the heart of an intact rat with the use of differential centrifugation. An introduction of mitochondria to mice was carried out daily intraperitoneally at a dose of 3.3 mg of protein for 3 weeks. Statistical analysis of the results is carried out with the Statistica 10.0 software. Results. On day 21 (week 3) of the experiment, macroscopically in the melanoma tissue in the group of animals with MC therapy, there were 2.5 times more necrosis cases than in the group without MC therapy. During the examination of the internal organs, no metastases were detected in the animals treated with MC therapy, while in 100% of the animals without MC therapy metastases were found in the lungs and in 95% of them in the spleen. In the animals received MC therapy, there was no damage to the heart muscle in 75% of the cases, while in the group of the animals without MC therapy, the presence of lesions in the form of bruises on the surface of the heart was macroscopically detected in 100% of the animals. Conclusion. Thus, intraperitoneal transplantation of intact heart mitochondria contributed to the prevention of myocardial infarction and metastases to internal organs in the C57BL/6 male mice with B16/F10 melanoma growing against the background of chronic neurogenic pain.

Authors: Misrohmasari Elyda Akhya Afida , Prihatiningrum Berlian
Published: June 2022

Dental caries is a multifactorial condition affected by behavioral factors. Parenting styles reflect different behavior influenced by cultural and socioeconomic backgrounds. Coastal areas have unique cultural and socioeconomic conditions and underlie the community's upbringing behavior. This study aims to determine the differences in preschool children's caries experience based on parenting patterns in a coastal area. This study is a cross-sectional study on children and their parents in the coastal area of Puger, Jember, East Java, Indonesia. The participants were 269 pairs of preschool children and parents selected by random cluster sampling. The dependent variable was dental caries experience measured using the def-t index. The independent variable was the type of parenting categorized into three groups (authoritative, authoritarian, permissive) based on a questionnaire distributed to parents. The Kruskal-Wallis test was applied to determine the difference in caries rates in each parenting style (p≤ 0.05). The results showed that the prevalence of primary teeth caries was 97%, and the mean of def-t was 10.03. Authoritative parenting style was the majority (81.8%), and no statistically significant difference was found between caries and parenting style (p=0.473). However, the mean of def-t in the authoritarian group was higher than in others (10.42). Based on the result, it can be concluded that mean of dental caries among children in a coastal area with authoritarian parents was the highest one compared to others, but the difference was statistically insignificant.

Dinámicas geopolíticas de las vacunas (covid-19) a la luz de la teoría de la dependencia
Authors: Sepúlveda Marín María Nicoll
Published: June 2022

La pandemia global de covid-19 ha llevado a una concentración de esfuerzos con el fin de aminorar los efectos de contagio y mortalidad. En este escenario, surgió el mecanismo Covax (Fondo de Acceso Global para Vacunas Covid-19), con el fin de garantizar un acceso equitativo a las vacunas, toda vez que múltiples organizaciones internacionales han denunciado el acaparamiento del 75% de ellas por parte de los diez países de más altos ingresos. Con base en lo anterior, este trabajo presenta un análisis de las dinámicas geopolíticas con respecto a las vacunas contra el covid-19 a partir de la teoría de la dependencia. Para este fin, se analizarán las cifras de producción, distribución, adquisición y aplicación de las vacunas a nivel global a partir de los principales planteamientos de la teoría de la dependencia, con el fin de exponer cómo en el escenario de la pandemia se evidencian desigualdades internacionales en ámbitos distintos al económico. Los hallazgos preliminares llevan a concluir que la teoría de la dependencia aporta herramientas clave a partir de su categorización centro-periferia y los escenarios de desarrollo dependiente y limitada autonomía. Así, se desvela como un marco analítico relevante para el estudio de las dinámicas geopolíticas y de la economía política internacional en el marco de la salud global.
Zona de Paz y Cooperación del Atlántico Sur: la clave en la soberanía del hemisferio sur
Authors: Álvarez Bertonasco Marina Belén , Luzzi Santana Marina
Published: June 2022

En la agenda de la seguridad internacional podemos encontrar que el mantenimiento de la paz, la cooperación internacional y la consolidación de la soberanía son temas transversales a nivel regional y en relación con las capacidades materiales. En este sentido, observamos que determinadas organizaciones internacionales se abocan a esta temática; el Sur global es una región que no es ajena a estos tópicos. A fin de reflejar la incidencia de las organizaciones internacionales como instrumentos de cooperación internacional, pero sobre todo como un vector para el ejercicio de soberanía, es que buscaremos responder a la pregunta: ¿es la Zona de Paz y Cooperación del Atlántico Sur una potencial herramienta para el reclamo de la soberanía argentina sobre las Islas Malvinas, Georgias del Sur y Sandwich del Sur? Para ello optamos por un marco de análisis institucionalista liberal, a fin de tener presente el uso de los foros multilaterales como elemento de soft power traducido en ejercicio de soberanía.

Genocidio del siglo XXI: el caso de los Rohingya
Authors: Riveros Parra Mateo Andrés
Published: June 2022

La presente investigación se propone describir, explicar y analizar el proceso de genocidio en Myanmar en contra de la comunidad rohingya. Los usos de la religión, las redes sociales y la identidad sirvieron como herramientas para justificar la violencia, eliminar al enemigo y ocultar la verdadera causa de la ofensiva militar contra la comunidad musulmana en 2017. Asimismo, el conflicto histórico entre las comunidades internas y el efecto de la apertura democrática y económica del país encaminaron a la sociedad de Myanmar hacia la condena de los rohingyas y a adquirir un lugar como actor en el genocidio. De esta manera, la sociedad legitimó al gobierno militar en las operaciones militares de 2017 que forzaron el desplazamiento de más de 700.000 rohingyas quienes, sumados a los más de 200.000 que ya habían migrado entre 2012 y 2015, se encuentran sin Estado ni derechos en el campo de refugiados más grande del mundo en Bangladesh.
¿Hacia una escuela china de relaciones internacionales? Enfoques predominantes y su concepción de la cooperación internacional
Authors: Marchetti Agustina
Published: June 2022

A partir del siglo XX, se empiezan a desarrollar enfoques teóricos no occidentales como alternativa a las teorías tradicionales de las relaciones internacionales. Algunos especialistas empezaron a debatir acerca de la emergencia y consolidación de una “escuela china de relaciones internacionales”, basada en su gran mayoría en la propia cultura del gigante asiático. El objetivo del artículo es presentar las principales corrientes de estudios internacionales en China, entre las que se destacan los enfoques reverso, anverso e interactivo. Asimismo, se pretende, en particular, comprender la concepción de cooperación internacional de cada uno de estos enfoques. Se parte de la hipótesis de que la producción y los cambios del eje de los estudios internacionales siguen el ascenso y la posición geográfica de las grandes potencias. En el caso de China han ido in crescendo en paralelo a su protagonismo internacional y al alcance del estatus de gran potencia. El marco teórico propuesto para esta investigación toma como punto de partida las llamadas non western theories, esto es, todas aquellas teorías que no forman parte del mainstream de las teorías de las relaciones internacionales occidentales.

How the Coronavirus Pandemic has Affected Gender Wage Inequality in Colombia
Authors: Botello-Peñaloza Héctor Alberto
Published: June 2022

This article aims to compare how gender wage differences among Colombian workers have changed before and during the coronavirus pandemic. The parametric breakdown of Oaxaca-Blinder is performed based on microdata from the 2020 Large Integrated Household Survey and compared with the 2019 results. Among the results, the differential in hourly labor income against women has increased to 16% in 2020 versus 4% in 2019, especially in the lower part of the distribution. For both years and all income levels, most of the contribution to the gap is due to the unexplained part associated with discrimination. However, this effect is counterbalanced by women’s contributions, which are highly concentrated in the upper-income brackets.
Lakáshelyzet egy szegregátumban

Published: June 2022

A tanulmány a szegregátum lakosainak életminőségét a lakhatás feltételein keresztül elemzi. A lakóterületen több változás történt az elmúlt két évben, azonban a lakótelep szegregációs jellege nem változott. A telep lakosainak mobilitása mutatkozik meg a telepre beköltözők és onnan kiköltözők tekintetében. A lakosság egyharmada a lebontásra került telepről költözött be a vizsgált szegregátumba az elmúlt két évben. A telep lakóépületeinek külső és belső felújításával a lakások megújultak, és a lakosok komfortos lakások bérlőkéiként élnek a telepen. A szegénység azonban továbbra is jellemző a telepen. A telep lakosai elsősorban kis alapterületű és zsúfolt lakásokban laknak, ahol a gyerekek rendszerint egy szobán osztoznak a felnőttekkel. A lakásfenntartás költségeinek növekedése komoly fizetési problémát jelent a telepen. Bár a lakások állapota a felújításokkal javult, azonban a zsúfoltság és a lakhatás kiadásainak növekedése nem hozott magával életszínvonal növekedést a lakhatást tekintve a telepen.

This report presents the results of the midline study of the Building Resilience in Crises through Education (BRiCE) research project, which is led by the Institute of Development Studies (IDS) and the Institut Supérieur Pédagogique de Bukavu (ISP Bukavu). The research project is part of the BRiCE education programme funded by the European Commission’s Directorate-General for International Partnerships and led by Save the Children in Niger and the Democratic Republic of the Congo (DRC). This report presents the results of the midline evaluation of two components of the BRiCE education programme: Teacher Professional Development (TPD) and Improving Learning Environments Together (ILET). It also presents an in-depth analysis of teacher wellbeing and teaching quality in the regions of Zinder and Diffa in Niger, and Uvira and Fizi in South Kivu province in the DRC. Specifically, the report explores several key factors in teachers’ wellbeing: their employment status, which structures inequalities in the teaching profession in Niger and the DRC; their social identity, with a particular focus on gender and ethnicity, which play an important role in teachers’ professional and social life; and their exposure to violence, analysing how violent conflict penetrates the school environment and affects teachers’ work.
The Environmental Impacts of War and Conflict
Authors: Khan Mahreen
Published: June 2022

In modern warfare, the first widely acknowledged scientific study and documented case of environmental damage during conflict was the (direct and deliberate) use of Agent Orange and other toxic chemicals by US forces, from 1961-1971, during the Vietnam War in a policy known as herbicide. The Vietnam War has been relatively well documented for the sheer horror and magnitude of the devastation to natural habitats and because it was the first war where television and global media brought vivid images and accounts into people’s homes, making the war a matter of political and public conscience This helped stir academic and scientific interest and facilitated evidence collection and documentation of environmental damages. This helpdesk report is a rapid literature review on the main environmental impacts of war and conflict, drawing primarily on academic, and peer reviewed literature and only some policy and practitioner sources, as per the request. Where current situations are discussed, such as the ongoing Ukraine war, a few blogs are referred to. Within the literature focused on the environmental impacts of conflict, common case studies include: the North Atlantic Treaty Organisation (NATO) bombing of Kosovo (1999), and the conflict in the Donbas region of Ukraine (2014). Interestingly there is comparatively less literature on the conflicts in Afghanistan (2001-2021), the Iraq-Iran War (1980-1988), the Gulf Wars (1991 and 2003), the Yemeni civil war (2014 – present) and the ongoing war in Syria (since 2011) despite their relatively greater severity, intensity and duration.

Key Considerations: Drivers Influencing Vaccination-related Behaviours Among Ukrainian Refugees in Poland
Authors: Richardson Erica
Published: June 2022

Refugees from Ukraine are entitled to free access to all health services in neighbouring countries, including routine vaccination services for children. All Ukrainian children in Poland for more than three months are expected to be vaccinated, and have proof of vaccination, either according to the Ukrainian national schedule or the Polish national schedule. During the initial phase of the emergency response, there have been concerns about low vaccination rates among refugees who are on the move. This brief is intended for local government actors, non-governmental organisations (NGOs) and international agencies in Poland who are supporting refugees. It summarises existing information about the factors influencing vaccination-related practices during this emergency phase. It also presents strategic and practical considerations to inform the design of interventions to create demand for routine immunisation among Ukrainian refugees. The brief begins with a historical overview of routine vaccination in Ukraine. Next, it explores how this shaped the vaccination of Ukrainians in Poland before the current conflict (from February 2022) and the attitude of Ukrainian refugees to receiving vaccination in Poland. Finally, it draws on ongoing research that highlights how refugees’ uncertain longer-term plans limit their vaccination uptake.
RCCE Strategies for Monkeypox Response
Authors: Schmidt-Sane Megan , Abbas Syed , Karam Soha , Palmer Jennifer
Published: June 2022

Given the health, social, and economic upheavals of the COVID-19 pandemic, there is understandable anxiety about another virus, monkeypox, quickly emerging in many countries around the world. In West and Central Africa, where the disease has been endemic for several decades, monkeypox transmission in humans usually occurs in short, controllable chains of infection after contact with infected animal reservoirs. Recent monkeypox infections have been identified in non-endemic regions, with most occurring through longer chains of human-to-human spread in people without a history of contact with animals or travel to endemic regions. These seemingly different patterns of disease have prompted public health investigation. However, ending chains of monkeypox transmission requires a better understanding of the social, ecological and scientific interconnections between endemic and non-endemic areas. This brief is intended to be read in conjunction with the companion brief entitled ‘Social Considerations for Monkeypox Response’.1 In this set of briefs, we lay out social considerations from previous examples of disease emergence to reflect on 1) the range of response strategies available to control monkeypox, and 2) specific considerations for monkeypox risk communication and community engagement (RCCE). These briefs are intended to be used by public health practitioners and advisors involved in developing responses to the ongoing monkeypox outbreak, particularly in non-endemic countries. This brief on RCCE strategies for monkeypox response was written by Megan Schmidt-Sane (IDS), Syed Abbas (IDS), Soha Karam (Anthrologica), and Jennifer Palmer (LSHTM), with contributions from Hayley MacGregor (IDS), Olivia Tulloch (Anthrologica), and Annie Wilkinson (IDS). It was reviewed by Will Nutland (The Love Tank CIC/PrEPster) and was edited by Victoria Haldane (Anthrologica). This brief is the responsibility of SSHAP.

Mächtig nah – Beeinflusst Macht die Wahrnehmung von Distanzen?
Authors:   , Schoen-Reynders Raffael Danilo
Published: June 2022

Die vorliegende Studie untersuchte den Einfluss von Macht auf die Wahrnehmung von Distanzen. Zudem wurde der Einfluss auf die Sicherheit bezüglich des eigenen Wissens und auf die Wahrnehmung der eigenen Körpergröße untersucht, sowie auf die Wahrnehmung von Raumgrößen und Raumvolumina. Hierfür wurde das subjektive Machtempfinden der Teilnehmenden (N = 120) mit einem neu entwickelten Szenario manipuliert, welches Elemente von imaginativen Rollenzuweisungen sowie episodischen Erinnerungsaufgaben vereint. Es folgte eine Reihe von Distanz-, Raumgrößen- und Raumvolumina-Schätzungen durch die beiden randomisiert zugewiesenen Gruppen („hohe Macht“ und „niedrige Macht“). Entgegen der Hypothesen zeigte die Bedingung der hohen Macht keine geringeren Distanz-, Raumgrößen- oder Raumvolumina-Schätzungen durch die Versuchspersonen als die Bedingung der niedrigen Macht. Dies kann als ein erstes Indiz dafür gesehen werden, dass Macht keinen Einfluss auf die Wahrnehmung dieser räumlichen Dimensionen hat. Für die Sicherheit bezüglich des eigenen Wissens fand sich ein kleiner Effekt. Die wahrgenommene Körpergröße unterschied sich nicht zwischen den Gruppen.

Background. Ultraviolet light in the UV-C band is also known as germicidal radiation, and it is widely used for decontamination and disinfection of environments, water, and food. The ultraviolet source transfers electromagnetic energy from a mercury arc lamp to an organism´s genetic material. When UV radiation penetrates the cell wall of an organism, it destroys the cell´s ability to reproduce, through a physical and not chemical process. Thus, the objective of this study was to evaluate the antimicrobial potential of a new UV-C generating device (Asepsis) against clinically important microorganisms that may be present in beauty centers.
Methods. We present here a set of tests performed on tools easy to find in beauty salons (hairbrushes, nail pliers, makeup brushes, and, due to the recent COVID-19 pandemic, face mask samples). They were individually contaminated with bacteria (Pseudomonas aeruginosa, Staphylococcus aureus, fungi (Microsporum canis, Trichophyton rubrum, Candida albicans, Malassezia furfur), and the Chikungunya virus. Different times of exposure were evaluated (1, 3, and 5 minutes).
Results. There was notable reduction in the microbial load in every test, in comparison with control groups. Best results were observed on face mask samples, while the makeup brush showed less reduction, even with longer periods of exposure.
Conclusions. Beauty salons present a risk of infections due to microbial exposure. The device tested can efficiently inactivate, in a short time, microorganisms contaminating most tools found in this setting. The device also showed promising results against enveloped virus.
Supporting students’ understanding of equivalent fractions using jelly

Fraction as part-whole is the key to further fractional understanding, such as equivalent fractions. A problem faced by students in equivalent fractions is that they understand one part without including the other parts. This article discusses how 4th-grade students understand fractions as part-whole and equivalent fractions using units of equivalent. Indonesian Realistic Mathematics Education-oriented learning environment using jelly context was developed and tested in two stages, involving six students with different levels of mathematics ability. The analysis of group discussions and students’ answers to the given tasks shows that students with low abilities have difficulty showing that 1/4 is one part of the four parts. The students only know fractions in a/b form without understanding their meaning. It impacts the construction of equivalent fractions as units of equivalent. High-ability students can easily do mathematization on 2/8 or 2/6 by making a cut pattern before cutting the jelly. The research contributes to learning design that begins with activities related to the fractions as part-whole.

Highlights:

Patients with IRSS I stage have the longest lag time than IVB stage.
Lag time is no significant with stage retinoblastoma.

 
Abstract:
Retinoblastoma is a rare neoplasm disease that occurs in children, generally under the age of two. Retinoblastoma is more prevalent in developing countries and is often associated with a late diagnosis. Such delays can lead to a poor prognosis. The time from the appearance of symptoms of retinoblastoma (onset) to the time of diagnosis is called lag time. Early diagnosis of retinoblastoma by paying attention to factors such as age, clinical symptoms, and laterality can help improve retinoblastoma survival rates, especially in developing countries. The purpose of this study was to analyze the relationship between the lag time to the stage of retinoblastoma patients at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia. This study was a retrospective analytical observational study using secondary data from retinoblastoma patients at the Ophthalmology Outpatient Unit at Dr. Soetomo General Academic Hospital, Surabaya, from January 2014 to December 2018. The data were analyzed using Kendall's tau-C test. No significant correlation was found between lag time and stage (p = 0.339). Patients with International Retinoblastoma Staging System (IRSS) I stage had the longest lag time (on average 28 months), and patients with stage IVB had the shortest lag time (on average four months). There was no correlation between lag time and retinoblastoma stage. However, there was a trend of patients with early stages delaying hospital visits, while patients with advanced stages in earlier to the hospital.
