Validation of back pain questionnaire in a popoulation of New Zealand adolescents
Authors: Macdonald Helen , Johnson Gillian M.
Published: February 2018

This study aimed to examine the content, convergent and discriminant validity of the Adolescent Back Pain Questionnaire (ABPQ) which was developed to gather lifestyle choices information regarding New Zealand (NZ) teenagers’ experience of low back pain (LBP). Twenty volunteers (mean age 16.41, SD 1.66 years) were recruited from a secondary school, private physiotherapy clinics and a local medical centre. Of these, 15 participants (mean age 15.50, SD1.59 years) had been diagnosed and/or had presented to physiotherapy with LBP and the remaining five participants (mean age 15.84, SD 0.93 years) had no history of LBP. All participants completed both the on-line ABPQ and the Nordic Back Pain Questionnaire (NBPQ), applied in random order, followed by an individual face-to-face interview regarding their preferences and opinions about the questionnaires. The results showed that responses to the ABPQ demonstrated convergent and discriminant validity as a self-report measure across four domains of LBP namely: life-time LBP prevalence, pain intensity, care seeking, and aetiology of LBP. Further, the language and comprehension contained in the ABPQ was found to be acceptable to NZ adolescents and the ABPQ clearly discriminated between those with, and those without, LBP; thereby providing a basis for the use of the instrument when screening for this condition in the NZ adolescent population.
Cuerpos suicidantes, cuerpos en ruptura: experiencias singulares de la muerte voluntaria y la rebelión al orden doméstico en Eclipses de Ana María Jaramillo
Authors: Ayram Chede Carlos Julio
Published: February 2018

El presente trabajo está derivado de la investigación Suicidantes, enamoradas y subersivas: la escritura de los cuerpos en la narrativa de Ana María Jaramillo presentada en la Universidad de los Andes en el año 2015. Este artículo inicia con una taxonomía de cuerpos en la obra Eclipses a través de la experiencia que algunos de estos tienen en relación con la muerte voluntaria; los cuerpos, que llamo suicidantes, engendran un proyecto corporal capaz de deshacer la lógica en la que se fundamenta la vida. Posteriormente, presento los cuerpos en ruptura, cuerpos que han intervenido una lógica de opresión encarnada en la metáfora del orden doméstico.

Dilema aplikasi akad berbasis sosial dan bisnis dalam industri asuransi syariah di Indonesia: antara fatwa dan fakta
Authors: Irkhami Nafis
Published: February 2018

This article examines the legal issues on sharia insurance industries in Indonesia. The focus is on the application of the dual contract. It is the combination of the tabarru’ (voluntary) and tijārah (business) bonds. This qualitative study used secondary data. It will be approached with taxonomic technique. It is used to figure out the legal problems. Theoretically, the contract scheme should separate the management of both contracts. In this case, the main contract is the tabarru’, while the second is an additional. However, the takāful industries in Indonesia are more focused on the additional contract rather than the main. Based on research, Islamic insurances in Indonesia did not separate the tabarru’ and tijārah fund managements. It means that they mixed the returns obtained from both sectors. This shows that the dualism of tabarru’ and tijārah contracts in sharia insurance in Indonesia is not in line with the fatwas of The National Sharia Council-The Indonesian Ulama Council (DSN-MUI) on Islamic insurance. However, this article also found that there are some guidelines of DSN-MUI which are ambiguous. This article offers an alternative scheme of both contracts from the perspective of fiqh al-mu’āmalah (Islamic economic law). The contract that can be applied by the takaful as tabarru’ is a fee-based (ujrah). While the most logical contract for the rest is a profit and loss sharing-based investment contracts.
Analisis implementasi wakaf wasiat polis asuransi syariah di lembaga wakaf al-Azhar Jakarta
Authors: Sulistiani Siska Lis
Published: February 2018

Waqf in Islam is one way to invest in property for the sake of the world and the hereafter. The development of waqaf must still be in the sharia corridor so that its ubudiyah and iqtishadiyah values remain. Islamic law will not be known even as DSN MUI has just released its fatwa in October 2016 which is the investment benefit and sharia life fatwa, but some sharia insurance institutions and wakaf institutions in Indonesia first applied this form of waqf. The legal status of a wakaf law on Islamic insurance policy under Islamic law includes productive wakaf. However, in terms of its ownership element as a waqf object has not been fully owned by wakif so ulama differed in opinion, although in principle has been owned by wakif, but still opens the dispute space because the waqf object is not yet fully owned. The wakaf law of syariah insurance policy itself is still potentially canceled by wakif or by sharia insurance if one of them wakif get difficulty paying the premium before maturity. Implementation of waqf syariah insurance policy at Al-Azhar Wakaf Institute Jakarta has not yet fully complied with the rules of Fatwa DSN MUI because the fatwa has just come out in the end of 2016 and socialized in early 2017, whereas the wakaf will be known as sharia insurance policy in the community.

Authors: Syam Hamdani M
Published: February 2018

The purpose of this study was to investigate the young people communication activities and purposes in coffee shops in Banda Aceh. The objectives of this study were to investigate why young people either male or female (in Banda Aceh) hang out at coffee shops and what they are doing there.

The method employs in this study are quantitative in nature.  The survey is used to collect the data needed for this study. A set of the questionnaire is distributed to 1,500 young people who were hanging out in coffee shops in Banda Aceh. The data collected were analyzed through SPSS in the form of percentages. 

The results showed that the main reasons for hanging out in the coffee shops, apart from drinking coffee, were to chat with friends, look for entertainment and fill in time. The main form of communication was small talk and amusement. At the same time, those who talked about their studies did not get satisfaction. These young people also usually used the internet while they were in the coffee shops – to play games, chat with (other) friends and also to get materials for study.

Limitations of this study were that only questionnaire was used to get the data. As a matter of fact, the interview should be done to get the detail data. However, this study has given valuable information for readers in general in relation to the activities and purposes of hanging out at the coffee shops among young people in Aceh.

This study has never been done before especially in Aceh. This study also provided current information on what communication activities and purposes of young people in coffee shops in Aceh.

A funkcionális élelmiszerek a különleges (speciális) élelmiszerek közé tartoznak, melyeknek a tápértéken és élvezeti értéken kívül még egészségvédő hatást is tulajdonítanak. Az utóbbi évtizedben új élelmiszerek készültek a krónikus szív- és érrendszeri, daganatos betegségek kockázatának csökkentése céljából. A funkcionális élelmiszerek olyan hagyományos, minden piacon megtalálható termékek, melyeket a jobb egészségvédő hatás érdekében módosítottak. Magyarországon az élelmiszereket vásárlók 16%-a választ egészségtudatosan, a táplálkozási útmutatókat követve. Legtöbben a tejtermékeket keresik, mert kalcium-tartalmuk révén csökkenthetik a csontritkulást, melynek előfordulása idősebb korban már egyre gyakoribb. Utóbbi években megnőtt az érdeklődés a gyümölcsök és zöldségek iránt, melyek jelentős antioxidáns-kapacitással rendelkeznek. A biológiailag aktív anyagok (vitaminok, ásványi anyagok, antioxidánsok) rendkívül eltérő mértékben halmozódhatnak fel az általunk ismert és termesztett növényekben, a tenyésztett állatokban, vagy a hasznos mikroorganizmusok sejttömegében. Intenzív gazdálkodásban a növény gyorsabban növekszik, több termést ad egységnyi területen, de kevesebb biológiailag aktív anyagot tartalmaz. Emiatt a belőlük előállított élelmiszereket mesterségesen kell kiegészíteni, dúsítani. Felmérések szerint az így készített élelmiszerek piaca nagyon jelentős és gyorsan növekvő, mert a rendszeresen sportolók, testépítők és nagyobb fizikai aktivitásra képes testedzők is érdeklődést mutatnak az egészséges táplálkozást biztosító élelmiszerek fogyasztására.

The Consequences of Corruption on Economic Growth in Mediterranean Countries: Evidence from Panel Data Analysis
Authors: Boussalham Hicham
Published: February 2018

This study attempts to assess the impact of corruption on economic growth in the Mediterranean countries, during the period from 1998 to 2007. Econometric analysis using panel regression has been adopted to test this effect. Individual effects models such as random effects model and fixed effects model were applied to the study sample of 160 observations, and to choose the suitable model, we implemented several tests. For our analysis, we used a basic model that includes the dependent variable GDP per capita as a factor of economic growth and the corruption perception index as the independent variable concerned. Then we completed the model with several standardized macroeconomic control variables mentioned above and applied the individual effects models. The outcomes illustrate that corruption has a negative impact on the selected Mediterranean countries’ economic growth.

Selenocyanates form an interesting class of organic selenium compounds as they serve as multifunctional agents (being the precursors of seleninic acids and diselenides in synthetic chemistry and as antimicrobial and cytotoxic agent in biology) and, due to their similarity with better known thiocyanates promise high biological activity. Yet whilst selenocyanates are common in synthetic chemistry, they are rarely considered in pharmaceutical design. Arylmethyl selenocyanates (1-13) have been synthesized and an insight into their structural properties using X-ray crystallography has been obtained. The compounds subsequently have been evaluated for their potential antimicrobial, nematicidal and cytotoxic activity. ADMET properties in vitro, using mutagenicity (AMES) and permeability (PAMPA) tests, have been determined. The compounds exhibit pronounced activity against various strains of bacteria (both Gram-positive and Gram-negative) and yeasts. Among them, benzylselenocyanate (1) represents the most active anti-ESKAPE agent, with potent antibacterial activity, especially against multidrug resistant MRSA strains (HEMSA 5). Our results demonstrate that the arylmethyl selenocyantes are not only non-mutagenic but also possess moderate cytotoxic activity against cancer cells.

Karakterisasi produk dengan difraksi sinar-X (XRD) menunjukkan bahwa fasa tunggal Aurivillius ditunjukkan oleh sampel dengan x = 0, 0,2, 0,4, dan 0,6. Refinement struktur dengan teknik Le Bail diketahui bahwa senyawa Aurivillius yang terbentuk sesuai dengan simetri ortorombik dan grup ruang A21am. Analisis dengan Scanning Electron Microscopy (SEM) untuk semua sampel memperlihatkan morfologi sampel berupa lempengan yang merupakan ciri khas senyawa Aurivillius. Nilai konstanta dielektrik sampel dan konduktivitasnya mengalami kenaikan dengan meningkatnya x. Konduktivitas paling tinggi dimiliki oleh sampel x = 0,2 yang diperkirakan akibat adanya interaksi pertukaran ganda (double exchange) antara Mn3+ dan Mn4+.

Synthesis of Aurivillius Compounds Ca1-xBi3,5 + xLa0,5Ti4-xMnxO15: Structure and Dielectric Properties. Synthesis of ferroelectric compounds based on a four-phase Aurivillius phase (n = 4) which is doped with La3+ and Mn3+ cations, Ca1-xBi3,5+xLa0,5Ti4-xMnxO15 with x = 0, 0.2, 0.4, 0.6, 0 , 8, and 1 were carried out by molten salts technique. Characterization of products using X-ray diffraction (XRD) revealed that the single phase Aurivillius was shown by the samples with x = 0, 0,2, 0,4, and 0,6. The results of refinement show that the Aurivillius phase formed has orthorhombic symmetry with A21am space group. Morphology analysis by scanning electron microscopy (SEM) for all samples shows the plate-like as the characteristic of Aurivillius compounds. The value of dielectric constant and conductivity of the samples increases as increase of x. The conductivity of x = 0.2 is the highest predicted due to the interaction of double exchange between Mn3+ and Mn4+.

Unlike other types of inorganic scales, carbonate and sulfide scales are directly correlated to the in-situ concentration of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S), which influence the local pH and availability of reactive species. The common approach to sulfide- and carbonate-scale prediction often does not account for three-phase CO2 and H2S partitioning at different temperatures and pressures throughout the system. This leads to the use of inaccurate compositions and pH values for the mineral-scaling calculations.

In this paper, we apply a rigorous work flow (step-by-step procedure) derived from a compositional pressure/volume/temperature (PVT) model to calculate molecular CO2 and H2S distribution, three-phase relative volume changes, compositional changes, and scale-precipitation trends from the reservoir to the wellhead-separation stage using commonly available surface field data, a full PVT software package, and scale-prediction software of the user's choice.

A simplified version of the work flow was previously applied to high-CO2 and -H2S gas/condensate wells with production of condensed water only (Verri et al. 2017b).

This paper focuses on the field application of our “Rigorous General Work Flow” (Verri et al. 2017a) to North Sea oil wells with high water-cut and medium H2S levels (approximately 2,200 ppmv in the separator-gas phase) to provide sulfide- and carbonate-scale-prediction profiles from reservoir to separator.

The combination of reservoir-, production-, and chemical-engineering models using specific iterative processes (within the work flow) has provided a new and rigorous step-by-step procedure for the prediction of combined sulfide and carbonate scales in oil and gas wells, which can be implemented by anyone using any PVT and scale-prediction software.
Critical Considerations for Analysis of RF-Thermal Recovery of Heavy Petroleum
Authors: Saeedfar Amin , Lawton Don
Published: February 2018

Recently, coupled electromagnetic-reservoir simulators based on full numerical schemes have been developed using commercial software packages. However, simplified analytical and semi-analytical models can provide useful and quick insight of the complicated coupling between radio wave propagation and transport phenomena in heavy oil reservoirs. In this study, we developed simplified coupled EM-thermal models to emphasize on two important aspects of radio frequency heating process, near-field analysis and insulated antenna setups. It will be shown how much thermal error can be introduced when a proper full-wave analysis is not taken into account. We will also demonstrate the thermal advantage of applying an insulated antenna over a bare antenna when radio waves are used for heating purposes. Another key aspect of radio-frequency heating process is to consider dependency of electrical properties to thermal and water saturation conditions. This one is more difficult to verify analytically and it will be done in the second part of this study.

Einkorn
is one of the oldest and important wheat species because of its increasing
economic value, agronomical technical properties, and health and sanitary
effects. Therefore, a faster tissue culture production protocol which may
ensure a fast einkorn production is desired. 
The tissue culture process first requires an efficient sterilization
technique of the explant to eliminate contamination factors in this hulled
species. In this study, we, thus, aimed to determine the effective einkorn
sterilization process for the removal of contaminating microorganisms without
the loss of germination capacity and viability. We tested 22 following
sterilant combinations with different concentration and exposure time: Ethanol,
Commercial Bleach, Tween 20, Mercury (II) Chloride, and Sterile Distilled
Water. On the other hand, obtained the data were analyzed by one-way ANOVA and
Duncan test, where p≤0.05 was accepted significant. Forty percent commercial
bleach which were applied fifteen minutes eliminated all microorganisms with a
92.6% seed germination. The second-best technique was one minute exposure of
70% ethanol which were followed by 10 minutes exposure of 20% commercial
bleach. This assured up to 89% germination and no contamination. The worst
results came from the mercury (II) chloride with 0% contamination and ≤ 25%
germination rate. Mercury (II) Chloride was both highly toxic on the seeds and
reduced the contamination. Commercial Bleach and Ethanol Chemicals were less
toxic while providing an acceptable sterilization.

BACKGROUND

Avatars and embodied agents are a promising innovation for human health intervention because they may serve as a relational agent that might augment user engagement in a behavioral change intervention and motivate behavioral change such as antiretroviral adherence and retention in care.

OBJECTIVE

This study aimed to develop a theory-driven talking avatar-like embodied agent mobile phone intervention guided by the information-motivation-behavioral skills model to promote HIV medication adherence and retention in care in young African American men who have sex with men (MSM).

METHODS

We performed 5 iterative focus groups in Chicago with HIV-positive African American MSM aged 18-34 years to inform the ongoing development of a mobile phone app. Participants for the focus groups were recruited from 4 University of Illinois at Chicago Community Outreach Intervention Project sites located in different high HIV incidence areas of the city and the University of Illinois at Chicago HIV clinic using fliers and word of mouth. The focus group data analysis included developing an ongoing list of priorities for app changes and discussion between two of the investigators based on the project timeline, resources, and to what extent they served the app’s objectives.

RESULTS

In this study, 16 men participated, including 3 who participated in two groups. The acceptability for an embodied agent app was universal in all 5 focus groups. The app included the embodied agent response to questions and antiretroviral regimen information, adherence tracking, CD4 count and viral load tracking, motivational spoken messages, and customizability. Concerns that were identified and responded to in the development process included privacy, stigma, avoiding the harsh or commanding tone of voice, avoiding negative motivational statements, and making reminder functions for a variety of health care interactions.

CONCLUSIONS

An avatar-like embodied agent mHealth approach was acceptable to young HIV-positive African American MSM. Its relational nature may make it an effective method of informing, motivating, and promoting health behavioral skills. Furthermore, the app’s ease of access, stigma-free environment, and audiovisual format may help overcome some adherence barriers reported in this population.

We examined the relationship between team task knowledge diversity and team creativity, and the moderating role of team status inequality, with a focus on organizational tenure and rank inequality. By adopting an input–process–output framework, we hypothesized that teams
would achieve high levels of creativity when they have a large pool of task-relevant expertise that is differentiated and specialized among team members, but the relationship would be weakened when team members have different statuses. We tested our hypotheses using data from 325 teams of
employees at 10 companies in South Korea. Results showed that task knowledge diversity was positively associated with team creativity and a team's status inequality in terms of organizational tenure moderated the relationship in a negative way. Our findings contribute to the literature on
team creativity by providing new insights regarding how status inequality, which is almost ubiquitous in workplaces, plays a role in a dynamic team process for creativity.

Published: February 2018

Introduction: The new Accreditation Council for Graduate Medical Education (ACGME) guidelines for family medicine residencies increased training requirements for caring for older adults. These guidelines prompted changes to the current geriatrics curriculum at the Trident/Medical University of South Carolina (MUSC) Family Medicine Residency Program. Changes to the training requirements and the residency geriatric experiences reflect an increasingly aging population and many unmet needs in caring for older adults.
Methods: To meet accreditation requirements and the needs of our population, the residency program established a new partnership with a continuing care retirement community (CCRC) and hired another provider to coordinate the curriculum. Changes to the curriculum included more time spent in our CCRC, better longitudinal patient visit continuity, a coordinated interprofessional didactic curriculum, more elective opportunities in geriatrics, and online pharmacotherapy quizzes. The curriculum was assessed with a validated 10-question pre/postresident survey.
Results: Resident responses revealed increased comfort in caring for a geriatric population, increased desire to focus on geriatrics in their medical career, and increased participation in the geriatrics track.
Conclusions: With changes in ACGME requirements, family medicine residency programs must develop a comprehensive curriculum to care for an increasing elderly population. The Trident/MUSC Family Medicine Residency provides a model curriculum for other programs seeking to improve training for their residents and meet these requirements.
