Knock-out power calls are options that incorporate barriers to the valuation of power calls. Introducing barriers to power calls reduces the costs to hold power calls which are known to have higher leverage than the standard vanillas. In this paper, we model the valuation of knock-out power calls using Crank–Nicolson and Monte Carlo simulation under Black–Scholes environment. Results show that Crank–Nicolson is more accurate and more efficient than Monte Carlo simulation for pricing knock-out power calls.

Authors:   Department of Mathematics and Statistics and Institute for Mathematical Research, Universiti Putra Malaysia, Alias I. A. , Hafidzuddin M. E. H. ,   Centre of Foundation Studies for Agricultural Science, Universiti Putra Malaysia
Published: February 2022

In this study, a problem of a magnetohydrodynamic (MHD) induced Navier slip flow over a non-linear stretching and shrinking sheet with the existence of suction is considered. Similarity transformation is used to transform the governing nonlinear partial differential equations into a system of nonlinear ordinary equations. The transformed ordinary differential equations are then solved by using the Shooting Method in Maple software. Dual solutions are obtained for certain governing parameters. The results obtained show that suction improves skin friction, while the slip parameter reduces shear wall stress. Moreover, it is established that the range of dual solutions for stretching sheet is smaller compared to the shrinking case.
Language shift: local language proficiency of the younger generation in Lampung
Authors:   Universitas Lampung, Riadi Bambang
Published: February 2022

Much research has been done on language shifting as a cultural product, but there is very little research on local language abilities and patterns, particularly in Lampung. Therefore, we aim to explain how local language skills and language patterns are among the younger generation. The descriptive method analyses the data obtained from the questionnaire given to the participants. The results showed that there had been a shift in local languages among the young generation of Lampung. The data explains that few young people are still fluent in local languages and use Indonesian to communicate in various domains. Thus, the younger generation gradually abandoned the local language as a cultural wealth of Indonesia. Study implications are also discussed, along with several recommendations for future studies. Keywords: local language shift, language proficiency, language patterns

Published: February 2022

Background: HIV and AIDS continue to challenge the health sector and economies in low and middle-income countries. Effectiveness condom use in preventing transmission of HIV is jeopardized due to recent reported decline in condom use. Alcohol serving venues are meeting points for sex partner which is a significant determinant of risk sexual practices while gender inequities impose challenges to women in negotiating safe sex.
Methods: Cross sectional exploratory study was conducted which deployed a qualitative method in data collection. Purposive sampling was used to select fourteen study participants. In-Depth Interview guide was used to gather information from female bar workers on perceptions and experiences in sexual relationships that are initiated following their interaction with male customers in alcohol serving settings and their negotiation for safe sex. This study explored sexual relationship power of Female Bar Workers (FBWs) in safe sex negotiations as they interact in alcohol serving venues in Kinondoni municipality in Dar es Salaam, Tanzania. Data was analysed manually by using thematic approach.
Results: Negotiation ability and sexual relationship power continue to be a key determinant of safe or unsafe sexual practices in sexual relationships of female bar workers. Although power to negotiate and make decisions towards safe sex was widely reported by female bar workers when they engage in casual sexual relationships, such power is outweighed by their own willingness to engage in multiple sexual relationships to supplement their meagre incomes.
Conclusion: Health promotion should continue to focus on behaviour change interventions with consideration of gendered roles and power in sexual relationships.
Informal Caregiving and Its Hidden Cost to National Economy- With a Toronto Case Study
Authors: Dong Weizhen
Published: February 2022

More than eight million Canadians are providing care for their aging family members, relatives, neighbours, or friends. Due to staff shortage, eldercare facilities are also relying on their residents’ families to fill the gap of the care needs. Caregiving responsibilities have forced many employees to take time-off from work or take early retirement, which is a heavy loss of productivity of Canada’s national economy. This study employed a mixed method strategy, and with both qualitative and quantitative data collection methods: interview, focus group discussion, and a questionnaire survey. It shows that Canadians must take time off from work or to leave jobs for providing care to their loved ones, even when they are residing in a long-term care setting. This seemingly private matter is a very public one in the other side of the coin: family caregivers’ lost time in employment is affecting Canada’s national economy significantly. Government should work with stakeholders to develop a national strategy to tackle the issue. COVID-19 outbreak has revealed long-term care institutions’ struggle with severe staff shortage in Canada.

Visual positioning system for marine industrial robot assembly based on complex variable function
Authors: Du Shuai , Oqaibi Hadi
Published: February 2022

With the deepening of human understanding of marine resources and the acceleration of resource development, marine industrial robots have come to be widely used. Robots are not simply a substitute for manual labour, but a personified electronic and mechanical device that combines human and machine strengths. They have both the ability to react quickly and analyse and judge the state of the environment, and the ability of the machine to work continuously for a long time, with high accuracy and resistance to adverse conditions. In industrial machinery, the gravitational field exists in threedimensional space, but if the distribution of the known field is independent of a coordinate, it is simplified to a twodimensional field, which is called a plane scalar field. There are many two-dimensional field problems in the visual positioning system of assembly system. The exact solution can be obtained by using complex function theory to analyse two-dimensional field in complex plane. In this paper, the application of complex function theory in gravitational field is discussed. In the process of cooperative assembly of marine industrial robots, it is necessary to make the correct choice to improve the cooperative assembly method of marine industrial robots, so that the robot industry in China can undergo development and renewal.
Social Implications of Corruption in Developing Countries: Case Study of Pakistan and India
Authors: Hassan Haris
Published: February 2022

Background

The existence of corruption threatens all aspect of a society, be that social, economic or political. Corruption is more pronounced in developing countries; however, it attracts very little attention from decision-makers. This paper analyses the social implications (health and education) of corruption in India and Pakistan. According to the Corruption Perception Index Report (2019), these countries are perceived to be the most corrupt ones.

Objectives

Corruption has been researched enormously with respect to its economic and political consequences, but not much attention has been given to its social implications on human rights. Corruption violates human rights directly or indirectly. Therefore, this paper aims to elaborate the links (direct and indirect) between corruption and human rights and focus on the consequences of corruption on health and education; it also aims to present anti-corruption policies to curb corruption in the investigated countries.

Methods

The research employs a systematic literature review method (PRISMA-P 2015) that identifies currently available research, selects and assesses contribution, analyses and synthesises data, and presents pieces of evidence with a justified conclusion. It also encourages researchers to apply PRISMA protocols in future researches.

Results

The results show that more than 80% of the reviewed articles argue that corruption is one of the invincible reasons for the people's dire social condition in India and Pakistan; moreover, corruption remains ignored, which shows that there are gaps to understand how corruption can extremely dent the right to education and health.

Abstract

Jengkol skin (Archidendron pauciflorum (Benth.) Nielsen) has antioxidant activity because it contains flavonoid compounds, saponins, and alkaloids, so jengkol skin can be used as a facial treatment. The peel off mask preparation was chosen because is one type of cosmetic that is easy to use because it utilizes the ability to release the film layer when applied to the skin so that it can increase comfort in use and is expected to increase the antioxidant activity of jengkol skin extract. Components of masks such as PVA (Polyvinyl Alcohol) which act as filming agents, affect the physical properties of the mask, because it is the material underlying the peel off mask. A stability test needs to be carried out to ensure the durability of the mask during storage. This study aims to determine the stability and antioxidant activity of peel off masks of jengkol skin from various concentrations of PVA. The method used is maceration with 70% ethanol solvent. PVA was used with concentrations of 6%, 8% and 10%. The physical properties test includes organoleptic test, pH test, homogenity test, adhesion test, dispersion test, dry time test, and viscosity test. The antioxidant test of peel off mask preparations was carried out by DPPH method (1,1 Difenyl-2-picrylhydrazil). Based on the results of the study, it was obtained that the peel off mask preparation was stable for a maximum of 21 days of storage. Formula with a PVA concentration of 10% is the formula that has the best physical properties during storage but is the most unstable formula because there are more white lumps than other formulas on the 28th day. The IC50 values ??were 420.9 ?g/mL, 397.4 ?g/mL and 434.1 ?g/mL

Modelling and forecasting the spread of COVID-19 pandemic: The Case of Vietnam
Authors: Mai Xuan Thanh , Mai Van Xuan
Published: February 2022

In examining the evolution of the COVID-19 pandemic in many countries since the beginning of the pandemic outbreak in early 2020, we found a common pattern of daily infections that has a skewed distribution with different peaks. This phenomenon applies the same when we observed the pandemic trend in Vietnam. Based on those observations, this study has adapted the skewed distribution function Logistic Growth (Skewed Logistic Growth - SLG) to develop our model for forecasting the COVID-19 infections. Taking Vietnam as the case study, the model focuses on the fourth outbreak - the largest and most complicated pandemic of the country to date. Results from the model have depicted a clear pattern that followed closely with the actual development of three infection waves during the fourth outbreak. This confirms that the model can be used to forecast the spread of COVID-19 in the coming time as the pandemic situation will be more complicated due to the appearance of new variants (i.e. Delta, Omicron...) along with critical adjustments in the government pandemic control and prevention strategies. The model forecasted the fourth outbreak would peak between the end of December 2021 and the end of January 2022, reaching about 16,000 new cases per day. The forecasting results are useful for the government and relevant agencies to proactively design timely and effective solutions for preventing solutions. It further proposes some directions for future research in order to enrich the methodological aspects and empirical evidence of the research domain.

Published: February 2022

El estudio es un análisis descriptivo cualitativo de diseño etnográfico a partir de los sucesos históricos y políticos del Sistema educativo de Chile, utiliza la ficha bibliográfica  de instrumento y la técnica de observación y revisión documental. Se aborda las decisiones políticas y económicas de su gobierno que afectaron al estudiante, su familia y la sociedad en general. El Estado actúa como administrador de recursos alineándose a sus objetivos ideales, para ello propone programas, contenidos y formas de evaluar. El sistema se desarrolla con vouchers y copagos por criterio de eficiencia. Los estudiantes se manifestaron con protestas nacionales contra la municipalización y segregación social que trajo la clasificación entre escuelas municipales, colegios particulares subvencionados y establecimientos particulares pagados además del tipo de evaluación ejecutada por el SIMCE sumada a las desigualdades socioeconómicas, geográficas y de capacidad pese a las leyes de equidad. Aunque se da la garantía de acceso al aprendizaje escolar y sus resultados son verdaderos logros a nivel latinoamericano.

Lima bean (Phaseolus lunatus L) is native to Latin America and has spread out
worldwide, thus having a high level of diversity. The lima bean seed from a specific
region might have different characteristics from others. This study was aimed to
characterize the physicochemical and protein of the dry seed of lima bean from Indonesia
based on its solubility, electrophoretic pattern, and amino acid profile. The result showed
that carbohydrate (68.89±1.55%) was the major component, with starch (41.96±1.10%) as
the predominant. The amylopectin was higher than amylose. Dietary fibre (27.87±0.37%)
was significant and dominated by insoluble one (25.47±0.32%). The fat content
(1.15±0.04%) was low and ash (3.67±0.47%) comprised of magnesium, phosphorus,
potassium, calcium, and iron with the content of 184, 75, 38, 11, and 10 mg/100 g,
respectively. Total phenolic compounds of this seed were 1.29±0.02 mg/g, phytic acid
11.57±0.03 mg/g, saponins 16.84±0.42 mg/g, and trypsin inhibitors 36.07±0.11 TIU/g.
HCN was found significantly at 30.99±0.29 ppm. Oligosaccharides were 5.93±0.29% that
comprised of raffinose 1.22±0.08% and stachyose 4.61±0.21%. Protein content was
moderate (15.93±0.55%) that comprised of albumin 18.47±0.62%, globulin 56.20±2.00%,
prolamin 3.14±0.20%, and glutelin 22.69±1.60%. The molecular weight of this protein
was 10-141 kDa with 12 polypeptides. Globulin had 12 polypeptides of 10 to 124 kDa.
Albumin had 18 to 116 kDa molecular weights, while glutelin had six polypeptides of 13
to 109 kDa. Prolamin did not have visible polypeptides. Lysine, leucine, valine, and
phenylalanine were the primary essential amino acids with high lysine but low methionine
and cysteine. In conclusion, lima bean seed is a source of carbohydrates and minerals,
with a moderate protein content dominated by the globulin. The polypeptide profile of
lima bean seed is varied depending on the protein fractions. The occurrence of antinutrition might hinder its utilization as a protein source. HCN as a toxicant should be
removed to obtain a safe seed for consumption.

Published: February 2022

The glyceride components such as glycerol, ester, mono and diglyceride are useful
components for food ingredients like food emulsifiers. One of the natural resources of the
glyceride component is refined bleached deodorized palm oil (RBDPO). This research
was aimed to analyze the glyceride component of the treatment variation of RBDPO. The
design of the research was completely randomized design (CRD) non-factorial with three
variables of treatment specifically the 9 g of RBDPO with 5 g glycerol (A), RBDPO (B)
and RBDPO with 0.7 g lipase enzyme Thermomyces lanuginosus immobilized (TLIM).
The concentration of glycerol, ester, mono- and diglyceride was tested by the gas
chromatography method. The data will be analyzed by using a descriptive method with a
boxplot and histogram. The results showed that the highest concentration of glycerol,
ester, mono- and diglyceride, respectively were shown in treatment B (1.5922%), C
(9.5699%), C (0.1783%), C (3.3329%). The boxplot graphic described that there was
statistically significant difference among the treatments.

Practice of sport, exercise or recreational physical activity increase the needs of energy and nutrients. Objectives are: 1) to evaluate BMI; 2) to assess the nutritional status; and 3) to test the association between BMI and KIDMED index. The study is realized on a sample of healthy young participants (N=101), aged 18 – 35, that do recreational sport activities such as: football (N=24), basketball (N=16), handball (N=15), volleyball (N=20), tennis (N=10), swimming (N=10) and martial arts (N=9). Body composition: height, weight, and BMI, were measured and calculated according to World Health Organization’s manual. A 16-item KIDMED questionnaire was used to assess nutritional status. KIDMED index was calculated after the KIDMED questionnaire was administered to all participants. Spearman’s rank correlation coefficient was applied to test the association between BMI and KIDMED index. We have assessed an optimal diet - medium quality, in physically active population that is involved in recreational sport such as: football, basketball, handball, volleyball, tennis, swimming and martial arts, and a normal healthy weight category based on BMI classification criteria of World Health Organization. In addition, we have found a weak positive association between BMI and KIDMED index in physically active population, that was not statistically significant. The outcome of the study indicates that most of the people that are regularly involved in physical activity have a decent nutritional awareness, as a result of the nutritional counseling they get from their coaches. It seems that recreational collective activities and sports, besides allowing people to gain knowledge about healthy eating skills and nutritional habits, also encourage them to bring the required changes in their diets. The impact of physical activity may be a promising area for future promotion of nutrition and health.

Restricting movement for the population and the impact of preventative measures due to the COVID-19 pandemic have spurred research interests in analyzing the healthy lifestyle of the student population. The aim of the study was to examine gender differences between students in physical activity, and the perceptions of physical fitness and well-being during lock-down due to COVID-19. The sample consisted of male (n=268; 25.9%; age 22.56±2.12) and female students (n=768; 74.1%; age 22.12±1.73) at the University of Sarajevo (UNSA). The questionnaire included questions and scales constructed to measure: physical activity, physical fitness, and the acute effects on well-being. χ² independence test were used to determine gender differences (p<0.05). Prior to the declaration of the COVID-19, there was a significant difference in the level of regular physical activity between male and female students at UNSA (p<.01). The data indicated that at that time 65% of male students were regularly physically active, while 45% of female students had regular physical activity. During the lock-down measures at UNSA: 46% of male and 40% of female students reported being regularly physically active and no significant differences were found in relation to gender (p>.05); 65% of male and 58% of female students reported a decline in physical fitness and significant gender differences were found (p<.05). After exercising male students reported better concentration and mood, more energy and motivation, and less nervousness in the range of 62–79%, while female students reported better concentration and mood, more energy and motivation, and less nervousness in the range of 62-81%. No significant differences were found in the physical activity acute effects on students' well-being in relation to gender (p>.05). Although gender differences in physical activity disappeared during the early phase of COVID-19 and lockdown measures, a more pronounced decrease in physical fitness was present in female students. The reported physical activity had equally positive acute effects on students' well-being.
