Published: February 2017

The temporal trend of inflammatory bowel disease (IBD) incidence is reported to be increasing in worldwide regions; however, reports focusing on China are sparse. The aim of this study was to provide an overview of the disease burden and clinical features of IBD in the Chinese population. We searched Medline, EMBASE, and another two Chinese databases. A parallel literature review and data extraction were conducted. Meta-analysis was performed to estimate the summary incidence rate of Crohn’s disease (CD) and ulcerative colitis (UC). The constituent ratios with 95% CI were calculated for clinical phenotypes and classifications. The literature review included 47 publications. The summary incidence rate of IBD was 1.74 (95% CI: 1.08; 2.40) per 100,000 person years, and the corresponding incidence rates of CD and UC were 0.40 (95% CI: 0.23; 0.57) and 1.18 (95% CI: 0.81; 1.56) per 100,000 person years, respectively. The sex distribution analysis indicated a male predominance in both CD (sex ratio: 1.64; 95% CI: 1.47–1.84) and UC (sex ratio: 1.29; 95% CI: 1.21–1.38). The clinical characteristics were summarized using data from 2283 CD cases and 17,958 UC cases; in which the majority of CD patients were diagnosed between 17–40 years of age, with non-stricturing and non-penetrating disease, varied disease locations, and less extra-intestinal manifestation. UC cases were featured with later disease diagnosis, a more severe disease course, more segmental lesions, and less extra-intestinal manifestations. Our study provided an estimated disease burden of IBD and demonstrated distinct clinical features in the Chinese population. Large-scale population-based studies are needed to further evaluate these findings.

Published: February 2017

The Open Geospatial Consortium (OGC) is committed to developing quality open standards for the global geospatial community, thus enhancing the interoperability of geographic information. In the domain of sensor networks, the Sensor Web Enablement (SWE) initiative has been developed to define the necessary context by introducing modeling standards, like ‘Observation & Measurement’ (O&M) and services to provide interaction like ‘Sensor Observation Service’ (SOS). Land surveying measurements on the other hand comprise a domain where observation information structures and services have not been aligned to the OGC observation model. In this paper, an OGC-compatible, aligned to the ‘Observation and Measurements’ standard, model for land surveying observations has been developed and discussed. Furthermore, a case study instantiates the above model, and an SOS implementation has been developed based on the 52° North SOS platform. Finally, a visualization schema is used to produce ‘Web Map Service (WMS)’ observation maps. Even though there are elements that differentiate this work from classic ‘O&M’ modeling cases, the proposed model and flows are developed in order to provide the benefits of standardizing land surveying measurement data (cost reducing by reusability, higher precision level, data fusion of multiple sources, raw observation spatiotemporal repository access, development of Measurement-Based GIS (MBGIS)) to the geoinformation community.

Published: February 2017

Recognizing both the stakes of traditional European common bean diversity and the role farmers’ and gardeners’ networks play in maintaining this diversity, the present study examines the role that local adaptation plays for the management of common bean diversity in situ. To the purpose, four historical bean varieties and one modern control were multiplied on two organic farms for three growing seasons. The fifteen resulting populations, the initial ones and two populations of each variety obtained after the three years of multiplication, were then grown in a common garden. Twenty-two Simple Sequence Repeat (SSR) markers and 13 phenotypic traits were assessed. In total, 68.2% of tested markers were polymorphic and a total of 66 different alleles were identified. FST analysis showed that the genetic composition of two varieties multiplied in different environments changed. At the phenotypic level, differences were observed in flowering date and leaf length. Results indicate that three years of multiplication suffice for local adaptation to occur. The spatial dynamics of genetic and phenotypic bean diversity imply that the maintenance of diversity should be considered at the scale of the network, rather than individual farms and gardens. The microevolution of bean populations within networks of gardens and farms emerges as a research perspective.
Investigating Autism-Related Symptoms in Children with Prader-Willi Syndrome: A Case Study

Published: February 2017

Prader-Willi syndrome (PWS), a rare genetic disorder caused by the lack of expression of paternal genes from chromosome 15q11-13, has been investigated for autism spectrum disorder (ASD) symptomatology in various studies. However, previous findings have been variable, and no studies investigating ASD symptomatology in PWS have exclusively studied children. We aimed to characterize social communication functioning and other ASD-related symptoms in children with PWS, and assessed agreement across measures and rates of ASD diagnosis. Measures included the Autism Diagnostic Observation Schedule-2 (ADOS-2), the Social Communication Questionnaire (SCQ), Social Responsiveness Scale-2 (SRS-2), Social Skills Improvement System-Rating Scales (SSIS-RS), and the Vineland Adaptive Behavioral Scales-II (VABS-II). General adaptive and intellectual skills were also assessed. Clinical best estimate (CBE) diagnosis was determined by an experienced developmental pediatrician, based on history and review of all available study measures, and taking into account overall developmental level. Participants included 10 children with PWS, aged 3 to 12 years. Three of the 10 children were male and genetic subtypes were two deletion (DEL) and eight uniparental disomy (UPD) (with a total of 6 female UPD cases). Although 8 of the 10 children exceeded cut-offs on at least one of the ASD assessments, agreement between parent questionnaires (SCQ, SRS-2, SSIS-RS) and observational assessment (ADOS-2) was very poor. None of the children were assigned a CBE diagnosis of ASD, with the caveat that the risk may have been lower because of the predominance of girls in the sample. The lack of agreement between the assessments emphasizes the complexity of interpreting ASD symptom measures in children with PWS.
Ovalbumin with Glycated Carboxyl Groups Shows Membrane-Damaging Activity
Authors: Tang Ching-Chia , Shi Yi-Jun , Chen Ying-Jung , Chang Long-Sen
Published: February 2017

The aim of the present study was to investigate whether glycated ovalbumin (OVA) showed novel activity at the lipid-water interface. Mannosylated OVA (Man-OVA) was prepared by modification of the carboxyl groups with p-aminophenyl α-dextro (d)-mannopyranoside. An increase in the number of modified carboxyl groups increased the membrane-damaging activity of Man-OVA on cell membrane-mimicking vesicles, whereas OVA did not induce membrane permeability in the tested phospholipid vesicles. The glycation of carboxyl groups caused a notable change in the gross conformation of OVA. Moreover, owing to their spatial positions, the Trp residues in Man-OVA were more exposed, unlike those in OVA. Fluorescence quenching studies suggested that the Trp residues in Man-OVA were located on the interface binds with the lipid vesicles, and their microenvironment was abundant in positively charged residues. Although OVA and Man-OVA showed a similar binding affinity for lipid vesicles, the lipid-interacting feature of Man-OVA was distinct from that of OVA. Chemical modification studies revealed that Lys and Arg residues, but not Trp residues, played a crucial role in the membrane-damaging activity of Man-OVA. Taken together, our data suggest that glycation of carboxyl groups causes changes in the structural properties and membrane-interacting features of OVA, generating OVA with membrane-perturbing activities at the lipid-water interface.

Published: February 2017

There is an urgent need for novel strategies to fight drug resistance and multi-drug resistance. As an alternative to the classic antibiotic therapy, attenuation of the bacteria virulence affecting their Quorum sensing (QS) system is a promising approach. Quorum sensing (QS) is a genetic regulation system that allows bacteria to communicate with each other and coordinate group behaviors. A new γ-lactone that is capable of inhibiting the LasI/R QS system, plakofuranolactone (1), was discovered in the extract of the marine sponge Plakortis cf. lita, and its structure, including absolute configuration, was determined by NMR spectroscopy, MS spectrometry, and quantum-mechanical prediction of optical rotation. The quorum quenching activity of plakofuranolactone was evaluated using reporter gene assays for long- and short-chain signals (E. coli pSB1075, E. coli pSB401, and C. violeaceum CV026) and was confirmed by measuring the total protease activity (a virulence factor which is under control of the LasI/R system) of the wild-type P. aeruginosa PAO1. Further research will be pursued to assess the potential of plakofuranolactone as a new antivirulence lead compound and a chemical tool to increase the knowledge in this field.

Published: February 2017

Low serum apolipoprotein (Apo) A1 concentrations and high serum ApoB concentrations may be better markers of the risk of cardiovascular disease than high-density lipoprotein (HDL) and low-density lipoprotein (LDL). However, the associations between modifiable lifestyle factors and Apo concentrations have not been investigated in detail. Therefore, this study investigated the associations between Apo concentrations and education, lifestyle factors and dietary intake (macronutrients and 34 food groups). These cross-sectional associations were examined among 24,984 individuals in a Swedish population-based cohort. Baseline examinations of the cohort were conducted between 1991 and 1996. Dietary intake was assessed using a modified diet history method. The main determinants of high ApoA1 concentrations (r between 0.05 and 0.25) were high alcohol consumption, high physical activity, non-smoking, and a low body mass index (BMI), and the main determinants of high ApoB concentrations were smoking and a high BMI. The intake of sucrose and food products containing added sugar (such as pastries, sweets, chocolate, jam/sugar and sugar-sweetened beverages) was negatively correlated with ApoA1 concentrations and positively correlated with ApoB concentrations and the ApoB/ApoA1 ratio, whereas the intake of fermented dairy products, such as fermented milk and cheese, was positively correlated with ApoA1 concentrations and negatively correlated with the ApoB/ApoA1 ratio. These results indicate that smoking, obesity, low physical activity, low alcohol consumption and a diet high in sugar and low in fermented dairy products are correlated with an unfavorable Apo profile.

Published: February 2017

Pueraria flowers have been used as a vegetable and an ingredient for tea and jelly. In this study, we investigated the effects of Pueraria flower extract (PFE) on endometriosis, a common gynaecological disease characterised by local sterile inflammation of peritoneal cavity. PFE suppressed the adhesion of human endometriotic cells 11Z and 12Z to human mesothelial Met5A cells. In addition, PFE significantly inhibited the migration of 11Z and 12Z cells as shown by woundhealing and transwell migration assays. PFE reduced the protein and mRNA levels of matrix metalloproteinase (MMP)‐2 and MMP‐9 in endometriotic cells. Moreover, extracellular signalregulated kinase (ERK)1/2 was activated by PFE treatment, and an ERK1/2 inhibitor, PD98059, significantly inhibited PFE‐inhibited cell migration in endometriotic cells. Furthermore, PFE significantly suppressed endometriotic lesion formation in a mouse model. These data suggest that Pueraria flower is a potential anti‐endometriotic agent for the inhibition of endometriotic cell adhesion, migration, and MMP expression.
Effect of 25% Sodium Reduction on Sales of a Top‐Selling Bread in Remote Indigenous Australian Community Stores: A Controlled Intervention Trial
Authors: McMahon Emma , Webster Jacqui , Brimblecombe Julie
Published: February 2017

Reducing sodium in the food supply is key to achieving population salt targets, but maintaining sales is important to ensuring commercial viability and maximising clinical impact. We investigated whether 25% sodium reduction in a top‐selling bread affected sales in 26 remote Indigenous community stores. After a 23‐week baseline period, 11 control stores received the regular‐salt bread (400 mg Na/100 g) and 15 intervention stores received the reduced‐salt version (300 mg Na/100 g) for 12‐weeks. Sales data were collected to examine difference between groups in change from baseline to follow‐up (effect size) in sales (primary outcome) or sodium density, analysed using a mixed model. There was no significant effect on market share (−0.31%; 95% CI −0.68, 0.07; p = 0.11) or weekly dollars ($58; −149, 266; p = 0.58). Sodium density of all purchases was not significantly reduced (−8 mg Na/MJ; −18, 2; p = 0.14), but 25% reduction across all bread could significantly reduce sodium (−12; −23, −1; p = 0.03). We found 25% salt reduction in a top‐selling bread did not affect sales in remote Indigenous community stores. If achieved across all breads, estimated salt intake in remote Indigenous Australian communities would be reduced by approximately 15% of the magnitude needed to achieve population salt targets, which could lead to significant health gains at the population‐level.

Published: February 2017

This paper reports the validation results of burst misalignment for ScanSAR-ScanSAR interferometry of the Phased Array-type L-band Synthetic Aperture Radar-2 (PALSAR-2) aboard the Advanced Land Observing Satellite-2 (ALOS-2, “DAICHI-2”). After the internal software modification on 8 February 2015, ALOS-2 ScanSAR observation mode archives have been available for use in interferometric analysis, as it was planned. However, it has not been reported whether its burst misalignment satisfies the mission requirements: 90% or higher burst overlap ratio. The validation results in this paper confirm that the expected observation misalignment satisfies the required range, including minimal seasonal and orbital dependencies. The results in this paper are obtained directly from the azimuth offset of the single look complex (SLC) data and are not derived from the orbit records. Nine identical orbits and frame numbers are chosen and evaluated to investigate the average burst misalignment and orbital dependency.
Modeling Vehicle Collision Angle in Traffic Crashes Based on Three-Dimensional Laser Scanning Data

Published: February 2017

In road traffic accidents, the analysis of a vehicle’s collision angle plays a key role in identifying a traffic accident’s form and cause. However, because accurate estimation of vehicle collision angle involves many factors, it is difficult to accurately determine it in cases in which less physical evidence is available and there is a lack of monitoring. This paper establishes the mathematical relation model between collision angle, deformation, and normal vector in the collision region according to the equations of particle deformation and force in Hooke’s law of classical mechanics. At the same time, the surface reconstruction method suitable for a normal vector solution is studied. Finally, the estimation model of vehicle collision angle is presented. In order to verify the correctness of the model, verification of multi-angle collision experiments and sensitivity analysis of laser scanning precision for the angle have been carried out using three-dimensional (3D) data obtained by a 3D laser scanner in the collision deformation zone. Under the conditions with which the model has been defined, validation results show that the collision angle is a result of the weighted synthesis of the normal vector of the collision point and the weight value is the deformation of the collision point corresponding to normal vectors. These conclusions prove the applicability of the model. The collision angle model proposed in this paper can be used as the theoretical basis for traffic accident identification and cause analysis. It can also be used as a theoretical reference for the study of the impact deformation of elastic materials.
Energy Generation from Horse Husbandry Residues by Anaerobic Digestion, Combustion, and an Integrated Approach
Authors: Nitsche Meike , Hensgen Frank , Wachendorf Michael
Published: February 2017

Horse-related activities often occur close to urban areas, where acreage for horse manure disposal is scarce, and subsequently alternative recovery options are necessary. Anaerobic digestion, direct combustion, and the integrated generation of solid fuel and biogas from biomass (IFBB) process are potential techniques focusing on energy provision. In this study, samples of horse faeces were analysed for chemical composition as pure feedstock and in mixture with straw or wood shavings, as well as for energy yield by biogas production or from combustion of solid fuel. It was observed that chemical properties of faeces, in a mixture with wood shavings, were promising for direct combustion, but achieved low methane yields. The methane yield of pure faeces and the straw mixture was 222.33 ± 13.60 and 233.01 ± 31.32 lN·kg-1 volatile solids (VS)added, respectively. The IFBB process divided the biomass into a press cake with reduced mineral concentration and a press fluid. Methane yields of press fluids were low (108.2 lN·kg-1 VSadded, on average). The chemical composition of the press cake allowed for combustion and led to a higher gross energy potential than anaerobic digestion (two-fold higher for pure manure and the mixture with straw, and five-fold higher for the mixture with shavings). Consequently, the gross energy potential of IFBB is higher compared to anaerobic digestion, however it should be noted that local conditions might favour the implementation of anaerobic digestion.

Published: February 2017

A comprehensive economic analysis of the associated costs and benefits derived from wastewater treatment is a prerequisite for ensuring long-term economic, environmental, and social sustainability. This study aims to improve the economic evaluation of wastewater reuse. A methodological framework is presented for the application of cost-benefit analysis to wastewater project plants. The method considers two alternative scenarios for the irrigation use of treated water: (i) for newly irrigated land; and (ii) as an alternative to current groundwater sources. A case study is carried out in Puglia, Southern Italy, where two thirds of irrigation water comes from groundwater. The results show that improved urban wastewater treatment would increase the regional availability of irrigation water by 60 million m3 per year, about 10% of the overall irrigation water demand. While treatment costs are highly dependent on the incoming effluent quality and plant size, the benefits are quite stable. These results point to a case-specific analysis, whereby the economic convenience of wastewater reuse could be assessed against the local context.
The MADE Reference Information Model for Interoperable Pervasive Telemedicine Systems
Authors: Jones Valerie M. , Hermens Hermie J. , Fung Nick L. S.
Published: February 2017

Objectives: The main objective is to develop and validate a reference information model (RIM) to support semantic interoperability of pervasive telemedicine systems. The RIM is one component within a larger, computer-interpretable "MADE language" developed by the authors in the context of the MobiGuide project. To validate our RIM, we applied it to a clinical guideline for patients with gestational diabetes mellitus (GDM).

Methods: The RIM is derived from a generic data flow model of disease management which comprises a network of four types of concurrent processes: Monitoring (M), Analysis (A), Decision (D) and Effectuation (E). This resulting MADE RIM, which was specified using the formal Vienna Development Method (VDM), includes six main, high-level data types representing measurements, observations, abstractions, action plans, action instructions and control instructions.

Results: The authors applied the MADE RIM to the complete GDM guideline and derived from it a domain information model (DIM) comprising 61 archetypes, specifically 1 measurement, 8 observation, 10 abstraction, 18 action plan, 3 action instruction and 21 control instruction archetypes. It was observed that there are six generic patterns for transforming different guideline elements into MADE archetypes, although a direct mapping does not exist in some cases. Most notable examples are notifications to the patient and/or clinician as well as decision conditions which pertain to specific stages in the therapy.

Conclusions: The results provide evidence that the MADE RIM is suitable for modelling clinical data in the design of pervasive tele-medicine systems. Together with the other components of the MADE language, the MADE RIM supports development of pervasive telemedicine systems that are interoperable and independent of particular clinical applications.

Using 25 years of data from uninterrupted monitoring of stellar orbits in the Galactic Center, we present an update of the main results from this unique data set: a measurement of mass and distance to Sgr A*. Our progress is not only due to the eight-year increase in time base, but also to the improved definition of the coordinate system. The star S2 continues to yield the best constraints on the mass of and distance to Sgr A*; the statistical errors of

Refractory organic compounds formed in molecular clouds are among the building blocks of the solar system objects and could be the precursors of organic matter found in primitive meteorites and cometary materials. However, little is known about the evolutionary pathways of molecular cloud organics from dense molecular clouds to planetary systems. In this study, we focus on the evolution of the morphological and viscoelastic properties of molecular cloud refractory organic matter. We found that the organic residue, experimentally synthesized at ∼10 K from UV-irradiated H2O-CH3OH-NH3 ice, changed significantly in terms of its nanometer- to micrometer-scale morphology and viscoelastic properties after UV irradiation at room temperature. The dose of this irradiation was equivalent to that experienced after short residence in diffuse clouds (≤104 years) or irradiation in outer protoplanetary disks. The irradiated organic residues became highly porous and more rigid and formed amorphous nanospherules. These nanospherules are morphologically similar to organic nanoglobules observed in the least-altered chondrites, chondritic porous interplanetary dust particles, and cometary samples, suggesting that irradiation of refractory organics could be a possible formation pathway for such nanoglobules. The storage modulus (elasticity) of photo-irradiated organic residues is ∼100 MPa irrespective of vibrational frequency, a value that is lower than the storage moduli of minerals and ice. Dust grains coated with such irradiated organics would therefore stick together efficiently, but growth to larger grains might be suppressed due to an increase in aggregate brittleness caused by the strong connections between grains.
A Bayesian Approach to Period Searching in Solar Coronal Loops
Authors: Scherrer Bryan , McKenzie David
Published: February 2017

We have applied a Bayesian generalized Lomb–Scargle period searching algorithm to movies of coronal loop images obtained with the Hinode X-ray Telescope (XRT) to search for evidence of periodicities that would indicate resonant heating of the loops. The algorithm makes as its only assumption that there is a single sinusoidal signal within each light curve of the data. Both the amplitudes and noise are taken as free parameters. It is argued that this procedure should be used alongside Fourier and wavelet analyses to more accurately extract periodic intensity modulations in coronal loops. The data analyzed are from XRT Observation Program #129C: “MHD Wave Heating (Thin Filters),” which occurred during 2006 November 13 and focused on active region 10293, which included coronal loops. The first data set spans approximately 10 min with an average cadence of 2 s, 2″ per pixel resolution, and used the Al-mesh analysis filter. The second data set spans approximately 4 min with a 3 s average cadence, 1″ per pixel resolution, and used the Al-poly analysis filter. The final data set spans approximately 22 min at a 6 s average cadence, and used the Al-poly analysis filter. In total, 55 periods of sinusoidal coronal loop oscillations between 5.5 and 59.6 s are discussed, supporting proposals in the literature that resonant absorption of magnetic waves is a viable mechanism for depositing energy in the corona.
Accounting for Chromatic Atmospheric Effects on Barycentric Corrections
Authors: Blackman Ryan T. , Szymkowiak Andrew E. , Fischer Debra A. , Jurgenson Colby A.
Published: February 2017

Atmospheric effects on stellar radial velocity measurements for exoplanet discovery and characterization have not yet been fully investigated for extreme precision levels. We carry out calculations to determine the wavelength dependence of barycentric corrections across optical wavelengths, due to the ubiquitous variations in air mass during observations. We demonstrate that radial velocity errors of at least several cm s−1 can be incurred if the wavelength dependence is not included in the photon-weighted barycentric corrections. A minimum of four wavelength channels across optical spectra (380–680 nm) are required to account for this effect at the 10 cm s−1 level, with polynomial fits of the barycentric corrections applied to cover all wavelengths. Additional channels may be required in poor observing conditions or to avoid strong telluric absorption features. Furthermore, consistent flux sampling on the order of seconds throughout the observation is necessary to ensure that accurate photon weights are obtained. Finally, we describe how a multiple-channel exposure meter will be implemented in the EXtreme PREcision Spectrograph (EXPRES).
A Team Formation Framework for Managing Diversity in Multidisciplinary Engineering Project
Authors: Hossain Shawqi Mohammed , Hasan Mahmudul , Murtuza Mohammed Golam
Published: February 2017

Team formation is one of the essential elements in constructing effective teamwork of any team size that requires different skill sets. Diversity in team encourages students to challenge and compete with one another while searching for new ideas, which in turn can lead to a better team performance. In a well-functioning diverse teams, the students who performed poorly may gain benefit by observing how excellent students approach the assignments. They may also benefit by getting advice and assistance from the excellent students. Studies have shown that Malaysian university graduates lack of team skills. The purpose of this paper is to propose a framework for forming a diverse multidisciplinary team among engineering undergraduates based on selected criteria such as individual personality type, gender, and other relevant demographic information. The proposed framework can also be used to design an automated team-formation system based on the identified metrics. The purpose of the framework is to consolidate the existing team formation literature, and to develop and test interventions for maximizing individual member and team performance as a whole that makes an effective team. For this study, a multidisciplinary approach was used where first year engineering students from three different faculties, namely Faculty of Electrical Engineering (FKE), Faculty of Mechanical Engineering (FKM), and Faculty of Biosciences and Medical Engineering (FBME) at Universiti Teknologi Malaysia (UTM) worked on an innovation project using the Conceive, Design, Implement, and Operate (CDIO) framework. Keirsey Temperament Sorter was used as an instrument to identify an individual's personality type.

Published: February 2017

China has a long-standing problem in second-language education, that is, the lack of communicative learning opportunities. This study attempts to solve the problem by introducing mobile-assisted language learning with WeChat instant messaging. WeChat is one of the most popular instant messaging applications in China. It offers five advantages for education: multi-functionality, individuality, accessibility, interactivity, and affordability. 50 students participated in a one-semester program. They were divided into two groups. One group learned English with the assistance of mobile applications (WeChat group), and the other learned English without assistance (Control group). A pre-test and a post-test were given, and the scores were analyzed. The results showed that students in the WeChat group significantly improved in English proficiency. The results suggest that mobile-assisted language learning helps to create language immersion, which effectively motivates the learners further. Therefore, mobile-assisted language learning is promising in English learning for college students.
Oh, as for the Health Insurance…it’s good, but…: rural elders in Agate, Ghana, discuss the National Healthcare Insurance Scheme

Published: February 2017

This paper investigates the Ghanaian National Healthcare Insurance Scheme (NHIS) through interviews with 28 elders over 50 years old with pre-existing illnesses in Agate, a rural village in Ghana. Our goals were to obtain snapshot views of the lives, in relation to health, wellness, and NHIS, of participants. Elders possessed reasonable information about NHIS. For most enrollees, NHIS provided peace of mind against financially-related health challenges, however, inability to afford non-covered medicines sometimes interfered with treatment. Most interviewees, insured or not, reported continuing chronic health problems. Based on qualitative data, we describe possibilities to improve elder experiences including: transportation to medical care, increased drug coverage, and faith-based health partnerships.
Nurturing constructive change that works: a critical theory-informed model for transforming health service psychologists’ views of people with disabilities
Authors: Gathercoal Roy O. , Gathercoal Kathleen A. , Seegobin Winston , Hadley Sarah
Published: February 2017

We have been developing and refining a disability training exercise for health service psychologists that is ever more effective at encouraging lasting change in the way students regard disabilities and the people who live with those disabilities. Although research suggests that simulation exercises tend to be ineffective at creating long-term attitude change in participants, quantitative and qualitative results indicate our exercise, composed of a simulation followed by debriefing and reflection, helps professionals better understand some of the challenges people with disabilities daily face, and how those challenges can affect their well being. We found this combination is more likely to yield long-term changes than any of these approaches alone. This paper is not principally the description of a pedagogical technique, but instead is an examination of how the combination of simulation, debriefing, and reflective journaling may challenge taken-for-granted assumptions about disabilities, e.g., that disabilities transform individuals into a different kind of human being (with either superhuman powers or as object of pity) instead of seeing these individuals as ordinary people facing extraordinary, and often society-created obstacles. One frequent call of Critical Theorists is to challenge those things we take for granted. Social and cultural structures create specific viewpoints and thus problematizing the apparent is necessary for understanding of, and emancipation from, potentially oppressive social structures. Inspired by this call to render the taken-for-granted as problematic, the exercise we describe creates inversions of performer/audience, professional/student, and scientist/researcher positions. In each of these inversions, the role of the objective observer is denied and the student is invited to engage in his or her own evaluative and potentially transformative experience. Through each of these inversions, different realities can be more readily utilized by thoughtful students to render problematic some of the dominant views about people with disabilities. To make this case, we utilize both qualitative and quantitative methods. The students’ own words, captured in their journals before and after the exercise, are examined in comparison with program goals and features. The weight of the evidence is impressive, indicating that the combination of simulation, debriefing and journaling reflection are effective at creating a space in which change of attitudes does occur.
Critical success factors of a business tourism destination: Supply side analysis
Authors: Marais Milandrie , Du Plessis Engelina , Saayman Melville
Published: February 2017

Orientation: Globally, destinations offer various products and services to visitors featuring different attributes and characteristics, making each destination unique. The critical success factors (CSFs) of each of these destinations may differ, making the management process more complex.Research purpose: The purpose of this research was to identify the CSFs for business tourism destinations in South Africa from a supply viewpoint.Motivation for the study: Because of the importance of CSFs, many previous studies have attempted to identify such factors within the tourism industry, but few concentrated on business tourism, especially in South Africa, leaving a gap in terms of knowledge. By means of identifying and understanding what these factors are for South Africa, the country could further develop its tourism sector, which could result in its being more competitive as a destination.Research design, approach and method: To achieve this goal, a qualitative research approach was followed by interviewing seven key business tourism coordinators in South Africa, to determine the key success factors of the business. The data gathered were transcribed and analysed using Creswell’s six steps in data analysis and interpretation.Main findings: Finances, human resources, product and customer-related aspects were identified as the CSFs for business tourism in South Africa.Practical/managerial implications: Educating the market and marketing value add-ons were identified as important for enhancing and making business tourism in South Africa more competitive.Contribution/value-add: The results could guide managers in the implementation of effective key success factors in an effort to mitigate management problems in a very competitive sector.
Community stakeholders’ perspectives on the role of occupational therapy in primary healthcare: Implications for practice
Authors: Naidoo Deshini , Van Wyk Jacqueline , Joubert Robin
Published: February 2017

Background: Primary healthcare (PHC) is central to increased access and transformation in South African healthcare. There is limited literature about services required by occupational therapists in PHC. Despite policy being in place, the implementation of services at grassroots level does not always occur adequately.Objectives: This study aimed at gaining an understanding of the challenges of being disabled and the services required by occupational therapists (OTs) in rural communities in order to better inform the occupational therapy (OT) training curriculum. Method: An exploratory, descriptive qualitative design was implemented using purposive sampling to recruit 23 community healthcare workers from the uGu district. Snowball sampling was used to recruit 37 members of the uGu community, which included people with disability (PWD) and caregivers of PWDs. Audio-recorded focus groups and semi-structured interviews were used to collect data, which were thematically analysed. Ethical approval was obtained from the Biomedical and Research Ethics Committee of the University of KwaZulu-Natal (BE248/14).Results: Two main themes emerged namely: firstly, the challenges faced by the disabled community and secondly appropriate opportunities for intervention in PHC. A snapshot of the social and physical inaccessibility challenges experienced by the community was created. Challenges included physical and sexual abuse, discrimination and marginalisation. Community-based rehabilitation and ideas for health promotion and prevention were identified as possible strategies for OT intervention.Conclusion: The understanding of the intervention required by OT in PHC was enhanced through obtaining the views of various stakeholders’ on the role. This study highlighted the gaps in community-based services that OTs should offer in this context.
Firm characteristics and excellence in integrated reporting
Authors: Buitendag Natasha , Fortuin Gail S. , De Laan Amber
Published: February 2017

Background: Integrated reporting has attracted much attention in the past few years, and South Africa has taken the lead in its development worldwide. An annual survey is published by Ernst & Young regarding the quality of the integrated reports of the top 100 entities listed on the Johannesburg Stock Exchange (JSE).Aim: The study on which this article is based was aimed at determining whether the assessment of an entity’s characteristics can predetermine the quality of the integrated report generated by that entity. Setting: This article focuses on an analysis of the integrated reporting of the top 100 entities listed on JSE for the financial years ending in 2013, 2014 and 2015.Methods: Comparison of categorical variables, mixed-model repeated measures ANOVA and generalised estimating equations were applied to identify the best classificators to distinguish between excellent integrated reporting and those reports where progress could still be made. Results: The results show that the type of industry the entity finds itself in, the size and profitability of the entity, as well as the composition of the members of the board, have an effect on the quality of the integrated report.Conclusion: Our results indicated that the type of industry, size of an entity, the profitability and composition of the board of directors, all have an effect on the quality of the integrated reporting. Our evidence will assist current and prospective stakeholders in evaluating the expected quality of an entity’s integrated report, through the evaluation of certain firm characteristics.
The preliminary urban missionary outreach of the apostle Paul as referred to in Acts 13�14
Authors: Mutavhatsindi Muthuphei A.
Published: February 2017

The objective of this article is to deal precisely and systematically with the preliminary urban missionary outreach of the apostle Paul as referred to the book of Acts, chapters 13�14. This article covers an ample spectrum of Paul�s mission work together with his companions. The book of Acts gives us a full exposition of the Holy Spirit as the primary agent of mission. The Holy Spirit led the church in Antioch of Syria in the dedication of Paul and Barnabas for their mission work which was specifically to the Gentiles as the Jews who were given the first preference rejected the Gospel (Ac 13:46). Christ in Acts 9:15 indicated his intention of choosing Paul as his chosen vessel to bear his name before the Gentiles, and kings, and the children of Israel, and this commission of Paul to the Gentiles was also referred to in Acts 22:21. The result of the apostles� propagation of the Word of God was that many Gentile people from different cities repented and became Christians. Although the apostles encountered many challenges and opposition, their initial campaign ended in a good mode, as they experienced the wonderful works of God to the Gentiles as God had opened a door of faith (salvation) among the Gentiles.Intradisciplinary and/or interdisciplinary implications: This article deals with missiological issues as it refers to Paul, who together with his crew encountered many challenges in their mission work like an opposition, expulsion, exaltation, stoning and so on. Even though they faced those challenges, they did not evacuate their responsibility of propagating the Word of God in different metropolitan areas. Thus where the element of �perseverance of the saints� of the Reformed Dogmatics comes in.
Human Factors in Forward Collision Warning Systems: Operating Characteristics and User Interface Requirements

Published: February 2017

Forward Collision Warning (FCW) systems are onboard systems intended to provide alerts to assist drivers in avoiding striking the rear end of another moving or stationary motorized vehicle. This SAE Information Report describes elements for a FCW operator interface, as well as requirements and test methods for systems capable of warning drivers of rear-end collisions.

This information report applies to original equipment and aftermarket FCW systems for passenger vehicles including cars, light trucks, and vans. This report does not apply to heavy trucks. Furthermore, this document does not address integration issues associated with adaptive cruise control (ACC), and consequently, aspects of the document could be inappropriate for an ACC system integrated with a FCW system.
Word and Church
Authors: Webster John
Published: February 2017

In Word and Church readers are treated to chapters that examine the field of Christian Dogmatics, presenting a clear trajectory in the work of John Webster, that moves from interpretation of 20th-century Protestant theology to doctrinal construction.

Webster addresses the modern traditions of Christian divinity, and the topics which come to the fore in making sense of these traditions: the nature of the Bible and its interpretation; the place of Jesus Christ in modern theological culture; and the basis and shape of human agency. As a whole the book boldly indicates how dilemmas or inadequacies in modern treatments of these topics might be clarified by more direct employment of language about God and the gospel.

The classic chapters present the work of one of the world's leading contemporary theologians at his creative best. For this Cornerstones edition the author has provided a new preface in which he contextualizes the work within his current theology.
