Does Ramadan influence the returns and volatility? Evidence from Shariah index in India
Authors: Munusamy Dharani 
Published: May 2019

PurposeMuslim’s hope that the holy month of Ramadan will create something more valuable for them. Through fasting and good actions, they can get rewarded twice than they normally can achieve. With this motivation, the purpose of this paper is to investigate the holy month of Ramadan effect on the returns and volatility of the Shariah index in India.Design/methodology/approachUsing the ordinary least square methods, this paper examines the impact of Ramadan effect on the returns of the Shariah index in India. This paper further investigates the impact of the holy month of Ramadan effect on the volatility of the Shariah index by applying GARCH-modified models. This paper categorizes the Ramadan days into three parts, namely God’s Mercy, God’s Forgiveness and Emancipation from hellfire to examine the relationship between the Ramadan effect and the returns and volatility of the Shariah index in India.FindingsThe results show that the returns during the month of Ramadan as a whole are statistically significant. The results further motivate that its last ten days have high influences than other days over the period. Finally, the study examines the Ramadan effect on volatility by applying GARCH modified models and finds an evidence of Ramadan effect during the first ten days of Ramadan month.Originality/valueThe positive impact of Ramadan increases on the days associated with higher worship intensity. The study provides an important information to the ethical investors to invest in the Shariah stocks during Ramadan days. This information is very useful for the investors to get an abnormal return during the Ramadan days.
Islamic religiosity and Islamic financial asset holdings (IFAH)
Authors: Zainudin Rozaimah , Mahdzan Nurul Shahnaz , Che Hashim Rosmawani , Sulaiman Noor Adwa 
Published: May 2019

Purpose
This paper aims to examine the relationship between Islamic religiosity and Islamic financial asset holdings (IFAH) among Muslim individuals in Malaysia.

Design/methodology/approach
Data for this study were collected through a survey questionnaire, and a sample of 751 working Muslims in Kuala Lumpur was obtained. Islamic religiosity was measured via religiosity levels and religiosity dimensions. IFAH was measured as the fraction of Islamic financial assets held in a financial portfolio. A generalized linear model (GLM) was used to estimate the relationships.

Findings
The results show that religiosity level influences the IFAH. Devout Muslims held more Islamic financial assets than casual Muslims. All religiosity dimensions influenced IFAH, with faith having the greatest influence and virtues the least. Educational level strongly influenced IFAH.

Research limitations/implications
The sample consisted of working Muslims in Kuala Lumpur; hence, generalization cannot be made to all Malaysian Muslims. This study only focused on Islamic financial assets and did not consider other types of Islamic financial products, such as financing.

Practical implications
Efforts to encourage Muslims to opt for Islamic financial assets may be more effective if they begin from the core of religious education. Educating individuals on Islamic principles, including the values and concepts of Islamic finance, is important to encourage the Islamic banking industry to prosper among Muslims.

Originality/value
The paper provides an extension of current literature on spirituality and religion by incorporating a comprehensive measure of Islamic religiosity and its relationship with financial asset holdings.
Extending the theory of planned behavior to explain the role of awareness in accepting Islamic health insurance (takaful) by microenterprises in northwestern Nigeria
Authors: Kazaure Mansur Ahmed 
Published: May 2019

Purpose
Nigeria is a country with very low health insurance coverage, with only 3 per cent of its population in the public and private sector covered by conventional health insurance. This made it possible for the exploration of alternative methods of insurance in Muslim dominated northwestern Nigeria. Thus, this paper aims to extend the theory of planned behavior to understand the role of awareness in the acceptance of Islamic health insurance (takaful) among microenterprises in northwestern Nigeria.

Design/methodology/approach
The methodology used was a purely quantitative survey with data collected from seven states that form the northwestern Nigeria.

Findings
The findings revealed that attitude, social influence and perceived behavioral control have a significant direct influence on takaful acceptance intention among microenterprises in northwestern Nigeria, while awareness does not. It was also discovered that awareness of takaful moderates the influences of social influence and perceived behavioral control on takaful acceptance intention, but it failed to moderate the influence of attitude on takaful acceptance intention in the same context.

Research limitations/implications
The implication is that despite the acceptance intention more awareness is required to enlarge the takaful market in the region. The study contributes to the theories of reasoned action and planned behavior through the integration of awareness as a moderator.

Originality/value
The work is pioneering, extent literature in the area of takaful failed in investigating the role of awareness as a moderating variables in Nigeria where much awareness of the concept is desirable.
Are non-Muslims willing to patronize Islamic financial services?
Authors: Wan Ahmad Wan Marhaini , Hisham Hanifa Mohamed , Hyo Kang Choong 
Published: May 2019

Purpose
The purpose of this paper is to investigate the awareness of non-Muslims coming from a non-Muslim-majority country regarding Islamic financial services, in particular, the takaful products.

Design/methodology/approach
This paper uses structured questionnaires to acquire and understand South Korean citizens’ perceptions of Islamic financial services (primarily takaful) to reinforce the scant previous literature in this area of research. The questionnaires are developed and adapted based on a previous study by Htay and Salman (2013). The sample consisted of 121 Korean people who were living in Ampang, a popular suburb for South Koreans in Kuala Lumpur.

Findings
The findings indicate that even South Korean citizens who have dwelled in Malaysia for a significant amount of time had little awareness of Islamic financial services. Upon personal explanation about the product, however, they showed a significant interest to get to know about takaful and a willingness to subscribe to it in the near future.

Research limitations/implications
Respondents are limited to only South Koreans who are residing in Malaysia.

Practical implications
Understanding the level of awareness about Islamic financial services among non-Muslims residing in Muslim-majority country.

Social implications
There is ample scope to penetrate the non-Muslim market for Islamic financial products.

Originality/value
There is a growing concern over the lack of research in the area of perceptions of Islamic financial services among non-Muslims from non-Muslim-majority countries. The lack of study in this area of research has often been overshadowed by research studies on perceptions of Islamic financial services among non-Muslim residents in Muslim-majority countries, which may have led to a dearth of proper strategies in the Islamic financial industry to penetrate non-Muslim-majority markets.

Published: May 2019

PurposeThis study is one of the first to address the types of tourism in contemporary standing in relation to the travel chronicle of Prophet Muhammad (PBUH). Consequently, this paper aims to identify the similarities between contemporary types of tourism and the premodern travelogue of Muhammad. Not many studies have been conducted relating to Islam, Muhammad and tourism.Design/methodology/approachMuhammad’s travel chronicle was reviewed through a content analysis of the Qu’ran, Hadith and Sirah. A literature review on contemporary types of tourism was conducted to synchronise the use of terminology from Muhammad’s premodern travels and contemporary types of tourism.FindingsIt is clear that the experiences being narrated in contemporary tourism were also experienced during Muhammad’s time, using different terminology but with similar connotations.Originality/valueThis study is one of the first to address the similarities between Muhammad’s premodern travelling and contemporary types of tourism. It is clear that several types of tourism that exist today were actually experienced and practiced by Muhammad.

Giant breast masses: A pictorial essay
Authors: Chitty Christopher , Dessauvagie Benjamin , Taylor Donna 
Published: May 2019

SummaryIn this pictorial essay, we showcase the imaging and pathological findings of a variety of giant breast lesions. Some lesions such as lipomas and hamartomas contain fibrous, glandular and lipomatous tissues and can have characteristic mammographic appearances. Other lesions (e.g. simple cysts, fibroepithelial lesions and some malignancies) may be mammographically indistinguishable and ultrasound (US) may be helpful in further characterisation, for example, by demonstrating posterior enhancement with simple cysts, cystic and solid components in papillary lesions, internal septations on haematomas and abscesses, solid homogeneity or heterogeneity in fibroepithelial lesions and increased vascularity in neoplastic, inflammatory or infective lesions. A diagnostic needle biopsy may be performed in some cases; however, with larger and heterogeneous lesions, there is an increased possibility of diagnostic inaccuracy due to limited sampling, such that full excision of the lesion may be advisable to ensure an accurate diagnosis.
The ironic effects of stigmatizing smoking: combining stereotype threat theory with behavioral pharmacology
Authors: Cortland Clarissa I. , Shapiro Jenessa R. , Guzman Iris Y. , Ray Lara A. 
Published: May 2019

AbstractAimsPublic service announcements often create media messages intended to stigmatize negative behaviors to reduce and prevent these behaviors. Drawing on social and cognitive psychology, we hypothesize that stigmatizing messages can create stereotype threat would be associated with shorter latency to first cigarette in the laboratory compared to the control condition.DesignA double‐blind, randomized, controlled trial in which participants completed two smoking lapse tasks, one at baseline and one post‐intervention/control.SettingAn experimental psychopharmacology laboratory in the western United States.ParticipantsA community sample of non‐treatment‐seeking daily smokers (n = 77) received either a stereotype threat (n = 39) or neutral/control (n = 38) message.InterventionParticipants received either a stereotype threat message that stigmatized smoking or a control message.MeasurementsThe primary outcome measure was participants’ ability to delay smoking during the smoking lapse task in the experimental sessionFindingsThe difference in delay time during the experimental session at the point where 50% of each group had smoked was 3 minutes. Cox proportional hazard models revealed that participants in the stereotype threat group were significantly less able to delay initiating smoking compared to the control group (hazard ratio = 0.504, P = 0.010, 95% confidence interval = 0.30, 0.85), after controlling for baseline latency to smoke.ConclusionsMessages that elicit negative stereotypes of smokers operated as ‘smoking‐promoting messages’ in the context of our controlled laboratory investigation.
A systematic review of research on adolescent solitary alcohol and marijuana use in the United States
Authors: Mason W. Alex , Stevens Amy L. , Fleming Charles B. 
Published: May 2019

AbstractBackground and AimsAlcohol use and marijuana use tend to be social activities among adolescents. Some youth use alcohol or marijuana while alone. This article provides a framework for examining the risk factors for and consequences of solitary alcohol and marijuana use, grounded in a motivational model that emphasizes coping with negative emotions, and provides the first systematic review of research on solitary alcohol and marijuana use among middle school‐ and high school‐aged adolescents in the United States.MethodsPubMed, PsycINFO and Web of Science were searched. Articles were included if they mention solitary alcohol or marijuana (or illicit drug) use among adolescents aged 12–18 years. Studies on non‐human animals, college students, non‐English language publications and articles exclusively about solitary tobacco or inhalant use were excluded. Overall, 22 articles were selected.ResultsPrevalence of adolescent solitary alcohol and marijuana use was relatively high (e.g. 14% life‐time solitary drinking in the general adolescent population), particularly in high‐risk subgroups (e.g. 38.8% life‐time solitary drinking in a sample of youth recruited from clinical and community settings). Risk factors for solitary alcohol and marijuana use include earlier onset and heavier use, coping motives, negative emotions and positive expectancies about use. Solitary alcohol and marijuana use are prospectively associated with later substance use disorder (SUD) symptoms, diminished academic performance and perceived health.ConclusionsApproximately 1 in 7 adolescents in the US appear to have engaged in solitary alcohol and marijuana use at some point. It is positively associated with extent of drinking and marijuana use, cop;ing motives, negative emotions, and positive expectancies, as well as subsequent SUD symptoms and poor academic and health‐related outcomes.
Evaluation of covariate effects on pharmacokinetics of monoclonal antibodies in oncology
Authors: Bajaj Gaurav , Suryawanshi Satyendra , Roy Amit , Gupta Manish 
Published: May 2019

AimsThe development of monoclonal antibodies (mAbs) requires an understanding of the interindividual variability (IIV) in pharmacokinetics (PK) at the population level facilitated by population PK (PopPK) modelling. However, there is no clear rationale for selecting which covariates to screen during PopPK model development. Here, we compare the effect of covariates on PK parameters for mAbs in oncology and identify the most commonly used covariates affecting PK parameters.MethodsAll 25 mAbs approved for therapeutic use in oncology until December 2017 by the Food and Drug Administration and the European Medicines Agency were selected for study. Literature searches revealed 23 available PopPK models for these mAbs. To understand the magnitude and types of covariate effect on PK parameters, all covariates included in the final PopPK model for each mAb were summarized.ResultsThe most commonly identified covariates were baseline body weight (BW; 17 mAbs), baseline serum albumin (8 mAbs), and sex (7 mAbs) on clearance; and BW (16 mAbs) and sex (12 mAbs) on central volume of distribution. A reduced PopPK model was developed for nivolumab and ipilimumab using these covariates, and the percentage of explained IIV from the reduced model (20.3% and 16.8%, respectively) was compared with that from the full model (24.5% and 27.9%, respectively).ConclusionsThis analysis provides a uniform platform for selecting covariates and suggests that the effect of BW, albumin and sex should be included during the development of PopPK models for mAbs in oncology. The reduced model was able to explain IIV to a similar extent as the full model.
Nickel allergy and allergic contact dermatitis: A clinical review of immunology, epidemiology, exposure, and treatment
Authors: Ahlström Malin G. , Thyssen Jacob P. , Wennervaldt Michael , Menné Torkil , Johansen Jeanne D. 
Published: May 2019

AbstractNickel is the most frequent cause of contact allergy worldwide and has been studied extensively. This clinical review provides an updated overview of the epidemiology, exposure sources, methods for exposure quantification, skin deposition and penetration, immunology, diagnosis, thresholds for sensitization and elicitation, clinical pictures, prevention, and treatment. The implementation of a nickel regulation in Europe led to a decrease in the prevalence of nickel allergy, and changes in the clinical picture and disease severity. Nevertheless, the prevalences of nickel allergy in the European general population are approximately 8% to 19% in adults and 8% to 10% in children and adolescents, with a strong female predominance. Well‐known consumer items such as jewellery and metal in clothing are still the main causes of nickel allergy and dermatitis, although a wide range of items for both private and occupational use may cause dermatitis. Allergic nickel dermatitis may be localized to the nickel exposure site, be more widespread, or present as hand eczema. Today, efficient methods for exposure quantification exist, and new insights regarding associated risk factors and immunological mechanisms underlying the disease have been obtained. Nevertheless, questions remain in relation to the pathogenesis, the persistent high prevalence, and the treatment of severe cases.
Quantifying data quality in a citizen science monitoring program: False negatives, false positives and occupancy trends
Authors: Cruickshank Sam S. , Bühler Christoph , Schmidt Benedikt R. 
Published: May 2019

AbstractData collected by volunteers are an important source of information used in species management decisions, yet concerns are often raised over the quality of such data. Two major forms of error exist in occupancy datasets; failing to observe a species when present (imperfect detection—also known as false negatives), and falsely reporting a species as present (false‐positive errors). Estimating these rates allows us to quantify volunteer data quality, and may prevent the inference of erroneous trends. We use a new parameterization of a dynamic occupancy model to estimate and adjust for false‐negative and false‐positive errors, producing accurate estimates of occupancy. We validated this model using simulations and applied it to 12 species datasets collected from a 15‐year, large‐scale volunteer amphibian monitoring program. False‐positive rates were low for most, but not all, species, and accounting for these errors led to quantitative differences in occupancy, although trends remained consistent even when these effects were ignored. We present a model that represents an intuitive way of quantifying the quality of volunteer monitoring datasets, and which can produce unbiased estimates of occupancy despite the presence of multiple types of observation error. Importantly, this allows the quality of volunteer monitoring data to be assessed without relying on comparisons with expert data.
A proposal for a 360° information system model for private health care organizations

Published: May 2019

AbstractAt a time when communication, new media, and digitalization are transversal to the whole of society, private health care organizations have the possibility of making their business processes evolve. The objective is thus to seize the benefits associated to the active use of patients' electronic health records (EHRs) as the basis for personalized health care. In order to initially validate the health care sector acceptance of a 360° health care information system (HIS), focused on collecting patients' data to create the necessary knowledge for delivering personalized health care procedures and initiatives, a focus group involving a set of health‐related professionals was performed. Despite recognizing the immense possibilities associated to EHR and its direct incorporation on a 360° HIS, the referred professionals still highlighted their concerns relative to the maintenance of adequate security and privacy levels. With this in mind, a proposal for a 360° HIS model is presented, and its main functional blocks are described with a focus on triggering patient/customer loyalty.
Cruciform specimens' experimental analysis in ultrasonic fatigue testing
Authors: Costa Pedro R. , Montalvão Diogo , Freitas Manuel , Baxter Richard , Reis Luis 
Published: May 2019

AbstractIn this paper, two special aluminium cruciform specimens are designed and tested in an ultrasonic fatigue machine. They were designed based on Single‐Input‐Multiple‐Output (SIMO) modal analysis to induce in‐plane biaxial stress combinations (in‐phase tension‐tension [T‐T] and out‐of‐phase compression‐tension [C‐T]) when at resonance at 20 kHz. The geometries were subjected to both numerical analysis and experimental testing to understand if they can indeed create the intended biaxial state of stresses. Both numerical and experimental results showed an impact of nearby resonant modes of noninterest on the correct functioning of the specimens, especially regarding the T‐T specimen where a large deviation from the mode of interest was measured. This means that future work includes re‐designing T‐T specimens taking into account these mode shapes. Only out‐of‐phase specimens demonstrated to work properly and tests until failure were conducted. The first failure results showed to be consistent with literature when out‐of‐phase biaxial stress is applied cyclically.

Authors: Mohapatra Dipti Ranjan 
Published: May 2019

AbstractRajasthan Urban Sector Development Program involved investment in water supply, sewerage, sanitation, and drainage, solid waste management (SWM), and etc. in major cities in the state of Rajasthan in India. This program was an initiative of the Government of Rajasthan and the Government of India carried out with a loan arrangement from Asian Development Bank. The phase II of the program was implemented in 15 cities of Rajasthan including Bharatpur with total investment of 1868.40 million Indian Rupees. The objective of this paper is to evaluate the economic viability of the infrastructure investments in Bharatpur in water supply, sewerage, sanitation, and drainage, SWM, and measure the impact on urban poor. Water supply, sewerage, sanitation, and drainage, and SWM subprojects are economically viable with internal rate of return (IRR) of 85.72%, 22.87%, and 39.34%, respectively. The sensitivity analysis shows above 12% IRR for all the above‐mentioned subprojects. The distribution of project benefits to the urban poor in Bharatpur is significant with poverty impact ratio of 9%.
