Published: February 2020

This article aims to study the patterns of Islamic discourses constructed by radical Islamic groups in social media. This article focuses on analyzing several Instagram accounts of the groups in shaping Islamic discourses. The discourses of Islamic radicalism were actually not a new idea, even now it has become one of the most talked phenomena. This study discusses the discourse of Islamic radicalism on social media, which is one of its missions is to promote the idea of formalizing Islamic sharia in Indonesia. The results showed that the forms of Islamic radicalism discourses on social media such as the invitation to avoid bid'ah, the campaign to implement Islamic law or Islamic state, Islamic Khilafah discourse that carries "anti-democracy", and a campaign to marginalize women's role in the public sphere. These issues are produced by radical Islamic groups through social media because these media are considered to be strategic and effective in campaigning their discourses as a means of ideological struggle. Fundamentalist Islamic groups are very keen to read the gap, they distinguish a change in the daily lifestyle of modern society which cannot be separated from the gadget. Therefore, they try to master and construct Islamic discourses in cyberspace with their point of view without considering to allow the differences of contextual understanding.

What do people mean when they talk about mindfulness?
Authors: Choi Ellen , Farb Norman A. S. , Pogrebtsova Ekaterina , Gruman Jamie , Grossmann Igor
Published: February 2020

Psychological theories cast mindfulness as a form of awareness in which accepting the presence of stressful thoughts and feelings facilitates engaged exploration and identification of adaptive responses. Critics of mindfulness’ popularization suggest that lay people misconstrue acceptance as a passive endorsement of experience, undermining engaged problem-solving. To evaluate this criticism, we traced the contemporary semantic meaning of mindfulness in three of the most extensive linguistic corpora of English language and found that general public’s depictions of mindfulness highlight engagement-related processes. We further analyzed the nomological network of mindfulness. While mindfulness theories suggest a general convergence of facets representing awareness and acceptance, in a meta-analysis (k = 145; N = 41,966) of the Five Facet Mindfulness Questionnaire only expert- and clinical samples reported convergence, whereas lay people showed absent or even antagonistic associations. Further, contrary to the synergistic model of awareness and acceptance contributing to greater engagement, empirical probes of two lay samples (Ntotal = 406) show that acceptance is either unrelated or inversely related to markers of engagement. To overcome resulting conceptual and methodological challenges, we highlight the need for a contextualized mindfulness framework whereby acceptance enables the process of engaging with life’s challenges rather than avoiding them.

Leaves of adult trees were collected at homogeneous plantations and isolated matrices, in the upper, middle and basal strata of the crowns totalizing 1800 sheets. The actual leaf area was determined using the “Area Meter” leaf area integrator (LI-3100C). In the estimation models, the leaf area was considered as a dependent variable, dry mass and leaf linear dimensions (length - C and width of the middle leaf - L) as independent variables. For calibration and statistical validation, 70% and 30% of the leaves were used in this order. In the statistical performance evaluation (validation) we used the mean error (MBE), quadratic root mean error (RMSE) and Wilmott adjustment index (dw). We used the method of weighted values of statistical codes (Vp) to define the best model. Models employing C and L joint measurements provide better estimates of T. grandis leaf limb area, with the AF = 0.5776 C * L model being overestimated 13.98 cm², scattering 61.99. cm² and adjustment of 0.99.

Published: February 2020

O objetivo deste trabalho foi realizar o mapeamento das áreas suscetíveis a ocorrência de incêndios na Estação Ecológica do Taim, Rio Grande do Sul. Para a obtenção das variáveis estáticas e dinâmicas, foram utilizadas imagens do satélite Landsat 8 e imagens de Radar para a determinação da topografia da área de estudo. Como variáveis dinâmicas utilizou-se a precipitação, temperatura e uso e cobertura da terra, enquanto que variáveis estáticas foram a hipsometria, declividade e distância das estradas. Cada variável foi estratificada e posteriormente ponderada numericamente quanto a sua suscetibilidade a ocorrência a incêndio. As variáveis dinâmicas e estáticas geradas foram integradas utilizando uma equação ponderada resultando no risco de incêndios para a área de estudo. A região central da Estação Ecológica do Taim apresentou maior suscetibilidade a incêndios, englobando a classe de alto risco, totalizando 4.219,56 ha (41,61%), enquanto as regiões periféricas apresentaram risco muito baixo a ocorrência de incêndios, abrangendo 5.419,35 ha (53,44%). As variáveis de maior contribuição à ocorrência de incêndios corresponderam ao uso e cobertura da terra e a temperatura, sendo as áreas de maior risco localizadas na parte central e próximo às estradas, nas quais estão ocupadas por campo nativo. Assim, esses locais devem ter maior atenção e recursos para combate de possíveis incêndios.Palavras-chave: Landsat 8; variáveis dinâmicas e estáticas; geoprocessamento. FIRE RISK AT THE ECOLOGIAL STATION OF TAIM, RIO GRANDE DO SUL ABSTRACT: The objective of this work was to map the areas susceptible to the occurrence of fires at the Taim Ecological Station, Rio Grande do Sul. In order to obtain the static and dynamic variables, Landsat 8 satellite images and Radar images were used to determine the topography of the study area. As dynamic variables were used the precipitation, temperature and land use and coverage, while static variables were hypsometry, slope and distance of roads. Each variable was stratified and numerically weighted as to its susceptibility to fire occurrence. The dynamic and static variables generated were integrated using a weighted equation resulting in fire risk for the study area. The central region of the Taim Ecological Station presented higher susceptibility to fires, encompassing the high risk class, totaling 4,219.56 ha (41.61%), while the peripheral regions had a very low risk of occurrence of fires, covering 5,419.35 ha (53.44%). The variables of greatest contribution to the occurrence of fires corresponded to the land use and land cover and the temperature, being the areas of greater risk in the central region and near the roads, in which they are occupied by the native field. Thus, these sites should have greater attention and resources to combat possible fires.Keywords: Landsat 8; dynamic and static variables; geoprocessing.

Of Whales and Dugongs: Examining the Rise of Colonial Conservation as Development in Madagascar's Marine History
Authors: Baker-Médard Merrill
Published: February 2020

This work explores how colonial marine conservation policy in Madagascar had the dual purpose of facilitating the expansion of capital and 'civilising' the way Malagasy fishers used marine resources. I analyse how the legacy of narratives that emerged to bolster state-led conservation intervention during the colonial period are still present in current conservation and development narratives, perpetuating in some cases the coloniser-colonised relationship between conservation organisations and local resource users. These findings indicate a need to revamp certain aspects of marine conservation legislation in Madagascar and the need for conservation organisations to explicitly acknowledge this history when working with local resource users in order to avoid reproducing historical injustices.

Authors: Kurniawati Ary , Badri Cholid , Ardiyanto Jeffri
Published: February 2020

Background: Callibration of  CT number and uniformity is very important to the CT QC program particularly when the program aims to ensure that the CT Scanner equipment operates within the manufacturer's specifications. Since the commercial CT QC phantom is not always available or affordable in the department, a simple, easy and cheap modified CT water phantom design could be useful to support further regular departmental CT QC program.Purpose: (1) to design , a simple and an easy to handle of the modified CT water phantom,  and (2) to verify its callibration and measurement functions based on to the gold standard of a commercial CT water phantom.Methods: This study is an experimental research laboratories, where a modified design of  CT water phantom is then compared to the comercial gold standard CT water  phantom. The commercial CT water phantom uses a cylindrical phantom that contains water with various diameter in sizes. In the modified CT phantom design, it filled with water as well, where the three different size in phantom diameters (15 cm, 20 cm and 32 cm recpectively) created for specific measurement purpose that of the CT Number and uniformity CT Number.Results: Calliberating the function of the modified CT phantom design resulted in the three observasional data. For all different phantom diameters (15, 20 and 32 cm) showed some variation about their CT number and homogenity. Most of the callibration and homogenity tests of the CT number in water deemed significant (cal. CT number for the 20 cm and 32 diameter phantoms, 0,001 0,05 and sig. 0,04 0,05 respectively), instead of that the uniformity test  of the phantom sized with 20 cm in diameter (0,432 0,05).Conclussion: A modified water CT phantom designed with 20 cm in diameter could be used for measurement of the CT number uniformity. Yet, measurements of the CT number callibration and uniformity needed to be consider againts from a failed measurement due to the phantom problem design with sizes at 20 and 32 cm in diameters.

Published: February 2020

Background:

The global prevalence of Alzheimer’s disease (AD) and its treatment costs are projected to increase significantly, placing increasing pressure on health systems to create new models of care. Community pharmacists are well-positioned to provide medication management for people with AD. In Arabic-speaking countries, little is known about pharmacists’ knowledge and practices in caring for people with AD.

Objective:

To evaluate community pharmacists’ knowledge of AD and its management, counseling skills, and dispensing patterns when caring for people with AD and their caregivers in the United Arab Emirates (UAE).

Methods:

A large-scale cross-sectional survey of community pharmacists was conducted in three cities in the UAE using stratified random sampling. The questionnaire comprised of validated tools to measure knowledge and open-ended questions. A logistic regression model was conducted to predict counseling comprehensiveness.

Results:

A total of 325 community pharmacists completed the questionnaire. The mean knowledge scores about AD and its pharmacotherapy were 57.0% and 67.6%, respectively. Major shortcomings in pharmacists’ practices were identified; history-taking, adherence assessment, and counseling were provided by 2.2%, 9.3%, and 17.3%, respectively. A minority provided comprehensive counselling; the multivariate analysis yielded new insights into pharmacist characteristics associated with such counseling.

Conclusion:

Pharmacists did not provide structured patient-centered care for people with AD. Community pharmacists did not provide adequate counseling, did not assess adherence-related issues appropriately, and had deficient knowledge. To develop patient-centered pharmacy-based services for Arabic-speaking communities, a multifaceted approach is required that goes beyond improving pharmacy workforce knowledge and communication skills to address broader sociocultural, legislative, and financial factors.

OBJECTIVES:

Inadequate testing (IT) and follow-up in infants with perinatal hepatitis C virus (HCV) exposure are challenging. We sought to identify maternal clinical and demographic risk factors that are associated with inadequate testing (IT) and follow-up of perinatally HCV-exposed infants.

METHODS:

In a retrospective cohort study spanning a period of 23 years, medical records of HCV-infected women and their perinatally exposed infants were reviewed for maternal characteristics that could be associated with their infants’ IT and loss to follow-up.

RESULTS:

A total of 27% (108/407) of HCV-exposed infants were adequately tested (AT) for HCV perinatal transmission. Among AT infants, HCV transmission rate was 11% (12/108). History of maternal intravenous drug use (IVDU) was significantly higher in IT vs. AT infants [88% (193/218) vs. 76% (70/92); p = 0.005]. The percentage of mothers on methadone maintenance treatment during pregnancy was higher in AT vs. IT infants [53% (35/66) vs. 34% (65/186); p = 0.010]. The percentage of mothers with HCV medical care was higher among AT than IT infants [54% (56/102) vs. 41% (106/255); p = 0.022].

CONCLUSIONS:

Infants born to HCV-infected mothers have suboptimal testing, possibly leading to an underestimation of the rate of HCV vertical transmission. Infants of mothers receiving HCV medical care and methadone treatment have improved testing. Infants of HCV-positive mothers with history of IVDU have lower rates of testing. Screening HCV-infected pregnant women for history of IVDU and linking them to drug treatment programs, and HCV medical care may improve testing and follow-up in their infants.

The Moderating Effect of Demography on the Interaction between Transformational Leadership, Employee's Engagement, Productivity and Commitment
Authors: Akey-Torku Benedicta , Dai Baozhen
Published: February 2020

As the global work environment keeps changing to suit the exigencies of the demands of the modern patient and employees, the issue of the influence of leadership in the healthcare sector has come to the fore. This paper seeks to evaluate the moderating influence of demographic variables on the interaction between transformational leadership and work engagement as well as between the influence of work engagement and organisational commitment. As disclosed in the framework the intervening variables are the gender, age and the level of experience of the respondents. Moreover this chapter highlights the influence that organisational commitment has on work performance of employees. The analysis leads to the rejection of the hypothesis that age and number of years of experience equally moderates the relationship between idealised influence and work engagement among hospital employees in Ghana. The findings of the study also reject the notion that gender moderates the relationship between intellectual stimulation and work engagement among hospital employees in Ghana. This was also observed in the case of the role of age and number of years of experience. It is instructive to note also that this findings reject the postulation that the number of years of experience moderates the relationship between intellectual stimulation and work engagement among hospital employees in Ghana, In the same regard this research rejects the idea that the number of years of experience moderates the relationship between idealised influence and work engagement among hospital employees in Ghana.
