Eastern Indonesia in Austronesian Perspective: The Evidence of Relational Terminologies
Authors: Fox James
Published: May 2017

This paper considers eastern Indonesia from two directions: from the direction of western Austronesia (including Taiwan) and from the direction of Oceania. The paper is concerned with regional variation in terminological relations: what terminological patterns have carried through to eastern Indonesia from the western Austronesian region; what patterns have been transformed; what patterns are distinctive of the region; and what relational patterns continue on into Oceania. Eastern Indonesia is a transition zone and is by no means uniform: hence the paper is also concerned to identify patterns of local variation within eastern Indonesia.
Environmental variability and human activity over the past 140 years documented by sediments of Ebinur Lake in arid central Asia
Authors: Liu Wen , Ma Long , Wu Jinglu , Abuduwaili Jilili
Published: May 2017

A short (50-cm-long) sediment core from Ebinur Lake in arid central Asia has been analyzed for various environmental proxies, including organic matter content, δ13C in organic matter, magnetic susceptibility, heavy metal contents, and stable isotopic compositions of bulk carbonate (δ18O and δ13C). The results reveal that the evolutionary stages inferred from environmental indicators have an asynchronous nature. If the asynchrony of periodic changes in multi-environmental proxies is ignored, important information may be lost, especially regarding anthropogenic influences. On the basis of magnetic susceptibility and heavy metal contents, human activities appear to have resulted in increases in surface erosion and measurable heavy-metal accumulation from the mid-1960s, whereas the organic matter contents, which display an obvious shift in the late 1930s, correlate with regional climate. However, the changes in the stable isotopes of bulk carbonate are mainly controlled by the isotopic composition of the host water which is generally consistent with the lake level. From the late 1870s to the 1960s, the lake was in a natural evolutionary state. From the 1960s to the mid-2000s, the runoff feeding Ebinur Lake dropped rapidly, in association with a sharp increase in agricultural development. Finally, beginning in the early twenty-first century, the climate became wetter than during the earlier two stages, and as agricultural water demand decreased, surface runoff once again increased. It is noted that, although the different proxies respond differently to climate changes and human activities, any analysis of environmental evolution should consider them each individually, in order to fully understand the complex interactions between climate and human influence. 
Dose-response relationships in gene expression profiles in a harbor seal B lymphoma cell line exposed to 17α-ethinyl estradiol
Authors: Kleinert Christine , Blanchet Matthieu , Gagné François , Fournier Michel
Published: May 2017

The determination of changes in gene expression profiles with xenobiotic dose will allow identifying biomarkers and modes of toxicant action. The harbor seal (Phoca vitulina) 11B7501 B lymphoma cell line was exposed to 1, 10, 100, 1000, 10,000, or 25,000 μg/L 17α-ethinyl estradiol (EE2, the active compound of the contraceptive pill) for 24 h. Following exposure, RNA was extracted and transformed into cDNA. Transcript expression in exposed vs. control lymphocytes was analyzed via RT-qPCR to identify genes with altered expression. Our analysis indicates that gene expression for all but the reference gene varied with dose, suggesting that different doses induce distinct physiological responses. These findings demonstrate that RT-qPCR could be used to identify immunotoxicity and relative dose in harbor seal leukocytes.

An African Reformation
Authors: Oliver Erna , Oliver Willem H.
Published: May 2017

The year 2017 is the year in which the Reformation, started by Martin Luther, is celebrating its 500th birthday. This depicts a milestone in the life of the Church of the Reformation and also in the life of Christians worldwide. This is a good time to ponder on the epistemological question of the validity and necessity of the (European) Reformation (i.e. improvement, renovation or change). If this question is answered in a positive way, then it could bring us to the realisation that the time is ripe for an African Reformation. This article will argue that this is indeed the case. A reformation, transformation and change is needed for the African Christian context. However, the question could well be asked: Who will be the ‘second Luther?’
Die Auslotung des Menschenmöglichen: Die Verschränkung von Sprache und Identität bei Hugo Loetscher
Authors: Grové Waldo , Mühr Stephan
Published: June 2017

Over the course of his career as a writer, Swiss intellectual Hugo Loetscher developed a fragmentary body of ideas on the themes of language and identity respectively. In this article, it is shown that these two themes may fruitfully be compared in five aspects. Firstly, Loetscher conceives of both as being deficient and as mere potentialities. Furthermore, he desires to experience the entirety of possibilities which being human could offer, with respect to the dimensions of language and identity. These interactions with language and identity subsequently leave him with unresolved issues, of which he thinks as a remainder. Lastly, his conception of a gamut of partial identities as human possibilities is also central to a language he wishes to invent. Although Loetscher’s ideas on these themes can only be extrapolated from his literary writings or essayistic fragments, a systematic treatment of these ideas in the context of philosophy of language reveals a unique and avant-garde way of thinking. This discussion leads to the realisation that Loetscher purposefully and repeatedly employs language and identity as synonymous with the possibilities of being human.
Human capital investments as sources of skills: An analysis at different entrepreneurship phases
Authors: Mamabolo M. Anastacia , Kerrin Myres , Kele Tumo
Published: May 2017

Background: Entrepreneurs need entrepreneurial skills to run their businesses. Skills can come from various sources, and the usage of the sources of skills can vary according to the different entrepreneurship phases.
Aim: Adopting a human capital theory perspective, this study determined the specific human capital investments as sources of skills needed by entrepreneurs across the different entrepreneurship phases. The sources of skills included work experience, formal education, entrepreneurship education and entrepreneurship experience.

Setting: Entrepreneurs at the different entrepreneurship phases which are nascent (entrepreneurs with ventures less than 3 months in existence), new business (entrepreneurs with ventures with more than 3 months but less than 3.5 years in existence) and established business (entrepreneurs with ventures more than 3.5 years in existence).

Method: The study employed a survey research design. An online questionnaire was used to collect the data.

Results: The results show that the sources of skills are used differently across the entrepreneurship phases. As entrepreneurs start businesses, in the nascent phase, the use of human capital investments (especially formal education) as a source of skills declines, thus creating a need to acquire more entrepreneurship-specific investments. In addition to acquiring skills from human capital investments, entrepreneurs learn skills from people in their social networks and self-taught skills which are used differently across the different entrepreneurship phases.

Conclusion: The findings indicate that the human capital investments are dynamic and change over time as the entrepreneurship phases unfold. Because there are different sources of skills for each entrepreneurship phase, entrepreneurs need to be treated according to their phases.

The evolution of physiotherapy in animal rehabilitation in Durban, Kwazulu Natal
Authors: Naidoo N. , Marr J. , Singh V. , Du Toit B. , Narisamulu N.
Published: June 2017

Introduction:Animal physiotherapy is a specialized branchof physiotherapy. As this specialization is not introduced at undergraduatelevel, there is a need to ascertain whether qualified physiotherapists had an interest in this field. The need for post-graduate interest in this subjectwould support a post-graduate programme as there is no academic insti -tutional programme in this field in South Africa.Aim of study:To gain information on the awareness of and interest in animalphysiotherapy from veterinary surgeons and qualified physiotherapists.Methodology: Two questionnaires were constructed, one for veterinarysurgeons and one for physiotherapists. Sixty physiotherapists and 30 veteri-nary surgeons in private practice in Durban, KwaZulu Natal participated in the study. A return of 73% of the question-naires for veterinary surgeons and 65% for physiotherapists was obtained. Data  analysis: Data  for  Physiotherapists  and  veterinary  surgeons  were  grouped  together  for  responses  to  the questionnaire and compared. Results: All physiotherapists and veterinary surgeons involved in the study are aware of animal physiotherapy. 81.5% of the veterinary surgeons administer physiotherapy treatment as part of their overall rehabilitation programmeand 7.41% refer their clients to physiotherapists. All the veterinary surgeons stated that physiotherapy is necessary inthe overall animal rehabilitation. 12.5% of physiotherapists treated animals and all felt under-qualified to treat animals.Conclusion: The study reveals a need for post-graduate specialization in animal physiotherapy and this would promote public awareness of its existence and benefit to animals.

Published: June 2017

Background: Hip fractures are among the most commoncauses of disability and hospitalisation in the elderly. There are no studies inSouth Africa that determine the effect of pre-fracture functional mobility onearly post-operative functional outcome in elderly patients with a hip fracture.Aim: The aim of this study was to determine the effect of pre-fracture functionalmobility on early post-operative functional outcome in elderly patients with ahip fracture.Methodology: A prospective pre-test post-test observational study designwas done. Assessments were conducted pre-operatively, at discharge and sixweeks post discharge at two public hospitals in Johannesburg, South Africa. Thepre-fracture functional mobility of the participants was determined using theNew Mobility Score (NMS) pre-operatively. At discharge and at six weeks post discharge the participants post-operative functionallevel was assessed using the Elderly Mobility Scale (EMS) and the Lower Extremity Functional Scale (LEFS).Results: More than two thirds of participants were independently mobile prior to the fracture. Pre-fracture functional mobilityis a strong determinant of early post operative functional outcome in elderly patients with a hip fracture(β = 1.39, p = 0.0001).Conclusion: Independent pre-fracture mobility predicts better early post-operative functional outcomes in the elderly.
The clinical value of brain computerised tomography in a general hospital psychiatric service
Authors: Chhagan Usha , Burns Jonathan K.
Published: May 2017

Background: The use of neuroimaging modalities in psychiatry has been evaluated in several studies. The vast majority seem to suggest that neuroimaging may be overutilised in psychiatry. There is a significant constraint on availability and cost related to neuroimaging of patients at general state medical facilities. The routine use of computerised tomography (CT) scanning is thus questioned.Methods: A retrospective analysis was undertaken of all psychiatric inpatients who had CT scans performed from 01 January 2011 to 31 December 2012. Demographic data, mental state examination, physical examination findings, substance use and diagnosis upon admission were recorded. The relationship between these variables and CT scan findings was analysed.Results: A total of 897 admissions were retrospectively analysed. One hundred and three patients had documented CT scan imaging. In total, 17 of the 23 patients with abnormal findings on CT scan were found to be psychotic (74.0%). The remaining 26.0% included depression and dementia. There was no statistically significant difference between the normal and abnormal CT scan groups with regard to gender, age, family history, substance use and physical examination. The majority (65.2%) had cerebral atrophy and/or cerebral calcifications. A smaller group of other documented findings was noted.Conclusions: Selective indications and clinical markers may be utilised in order to justify brain imaging studies rather than performing them routinely. That being true, a multicentre study with a larger sample size is indicated to further improve the statistical significance and assist in formulating a more concrete guideline for neuroimaging of psychiatric patients.

Improving Medication Adherence with Two-way Short Message Service Reminders in Sickle Cell Disease and Asthma
Authors: Pernell Brandi , DeBaun Michael , Becker Kathleen , Rodeghier Mark , Bryant Valencia , Cronin Robert
Published: May 2017

Introduction: Sickle cell disease (SCD) is a childhood and adult disease that primarily affects African Americans, characterized by life threatening sequelae mitigated by medications. One-way and two-way short message service (SMS) medication reminders have differing efficacy in chronic diseases. There is limited literature about SMS medication reminders in SCD.

Objective: The goal of this study was to test the feasibility, defined by recruitment/acceptance, retention/attrition, and technology utilization, of two-way SMS medication reminders in individuals with SCD with and without asthma.

Materials and Methods: Participants were randomly allocated to standard care or reminders. Two-way SMS reminders were automated using Research Electronic Data Capture (REDCap) for hydroxyurea, fluticasone, budesonide and montelukast. Adherence was measured using the Morisky Medication Adherence Scale-8 (MMAS-8). Asthma control was assessed using the Childhood and Adult-Asthma Control Tests (ACT). Participants were enrolled 28 to 60 days with a common termination date.

Results: The recruitment rate was 95% (47/49) and 82.9% completed the study. Among the 47 study participants enrolled, 51.1% were male, 61.7% were adults, median age was 20 (range: 3 to 59), and 98% were African Americans. Of the 26 participants receiving messages, 20% responded on over 95% of the days and usage varied with an average response rate of 33%, ranging from 21% to 46%. Medication adherence scores improved significantly in the intervention group (3.42 before, 5.46 after; p=0.002), but not in the control group (3.90 before, 4.75 after; p=0.080). Childhood-ACT scores improved in the intervention group (19.20 before, 24.25 after). Adult-ACT scores within the intervention arm were unchanged (21.0 before, 22.0 after. ACT scores did not improve significantly.

Conclusion: This study demonstrated the feasibility for two-way SMS medication reminders to improve medication adherence in a high-risk population where daily medication adherence is critical to health outcomes and quality of life.

Abstract. Routine cloud, precipitation and thermodynamic observations collected by the ARM Mobile Facility (AMF) and Aerial Facility (AAF) during the two-year DOE ARM Observations and Modeling of the Green Ocean Amazon (GoAmazon2014/5) campaign are summarized. These observations quantify the diurnal to large-scale thermodynamic regime controls on the clouds and precipitation over the undersampled, climatically important, Amazon basin region. The extended ground deployment of cloud-profiling instrumentation enabled a unique look at multiple cloud regime controls at high temporal and vertical resolution. This longer-term ground deployment coupled with two short-term aircraft intensive observing periods allowed new opportunities to better characterize cloud and thermodynamic observational constraints as well as cloud radiative impacts for modeling efforts within typical Amazon ‘wet’ and ‘dry’ seasons.
Validation of spectroscopic gas analyzer accuracy using gravimetric standard gas mixtures: Impact of background gas composition on CO2 quantitation by cavity ring-down spectroscopy
Authors: Lim Jeong Sik , Park Miyeon , Lee Jinbok , Lee Jeongsoon
Published: May 2017

Abstract. Effect of background gas composition on the measurement of CO2 levels was investigated by wavelength-scanned cavity ring-down spectrometry (WS-CRDS) employing a spectral line centered at the R(1) of the (3 0° 1)III ← (0 0 0) band. For this purpose, eight cylinders with various gas compositions were gravimetrically and manometrically prepared within 2σ = 0.1 %, and these gas mixtures were introduced into the WS-CRDS analyzer calibrated against standards of ambient air composition. Depending on the gas composition, deviations between CRDS-determined and gravimetrically (or manometrically) assigned CO2 concentrations ranged from −9.77 to 5.36 μmol/mol, e.g., excess N2 exhibited a negative deviation, whereas excess Ar showed a positive one. The total pressure broadening coefficients (TBPCs) obtained from the composition of N2, O2 and Ar thoroughly corrected the deviations up to −0.5–0.6 μmol/mol, while these values were −0.43–1.43 μmol/mol considering PBCs induced by only N2. The use of TBPCs enhanced deviations to be corrected to ~ 0.15 %. Furthermore, the above correction linearly shifted CRDS responses for a wide extent of TPBCs ranging from 0.065 to 0.081 cm−1 atm−1. Thus, accurate measurements using optical intensity-based techniques such as WS-CRDS require TBPC-based instrument calibration.
A 21 000-year record of fluorescent organic matter markers in the WAIS Divide ice core

Published: May 2017

Abstract. Englacial ice contains a significant reservoir of organic material (OM), preserving a chronological record of materials from Earth's past. Here, we investigate if OM composition surveys in ice core research can provide paleoecological information on the dynamic nature of our Earth through time. Temporal trends in OM composition from the early Holocene extending back to the Last Glacial Maximum (LGM) of the West Antarctic Ice Sheet Divide (WD) ice core were measured by fluorescence spectroscopy. Multivariate parallel factor (PARAFAC) analysis is widely used to isolate the chemical components that best describe the observed variation across three-dimensional fluorescence spectroscopy (excitation–emission matrices; EEMs) assays. Fluorescent OM markers identified by PARAFAC modeling of the EEMs from the LGM (27.0–18.0 kyr BP; before present 1950) through the last deglaciation (LD; 18.0–11.5 kyr BP), to the mid-Holocene (11.5–6.0 kyr BP) provided evidence of different types of fluorescent OM composition and origin in the WD ice core over 21.0 kyr. Low excitation–emission wavelength fluorescent PARAFAC component one (C1), associated with chemical species similar to simple lignin phenols was the greatest contributor throughout the ice core, suggesting a strong signature of terrestrial OM in all climate periods. The component two (C2) OM marker, encompassed distinct variability in the ice core describing chemical species similar to tannin- and phenylalanine-like material. Component three (C3), associated with humic-like terrestrial material further resistant to biodegradation, was only characteristic of the Holocene, suggesting that more complex organic polymers such as lignins or tannins may be an ecological marker of warmer climates. We suggest that fluorescent OM markers observed during the LGM were the result of greater continental dust loading of lignin precursor (monolignol) material in a drier climate, with lower marine influences when sea ice extent was higher and continents had more expansive tundra cover. As the climate warmed, the record of OM markers in the WD ice core changed, reflecting shifts in carbon productivity as a result of global ecosystem response.
All-in-one model for designing optimal water distribution pipe networks
Authors: Aklog Dagnachew , Hosoi Yoshihiko
Published: May 2017

Abstract. This paper discusses the development of an easy-to-use, all-in-one model for designing optimal water distribution networks. The model combines different optimization techniques into a single package in which a user can easily choose what optimizer to use and compare the results of different optimizers to gain confidence in the performances of the models. At present, three optimization techniques are included in the model: linear programming (LP), genetic algorithm (GA) and a heuristic one-by-one reduction method (OBORM) that was previously developed by the authors. The optimizers were tested on a number of benchmark problems and performed very well in terms of finding optimal or near-optimal solutions with a reasonable computation effort. The results indicate that the model effectively addresses the issues of complexity and limited performance trust associated with previous models and can thus be used for practical purposes.
The Usumacinta-Grijalva beach-ridge plain in southern Mexico: a high-resolution archive of river discharge and precipitation

Abstract. The beach-ridge sequence of the Usumacinta-Grijalva delta borders a 300-km-long section of the Southern Mexico Gulf coast. With around 500 beach ridges formed in the last 6500 years, the sequence is unsurpassed in the world in terms of numbers of individual ridges preserved, continuity of the record, and temporal resolution. We mapped and dated the most extensively accreted part of the sequence, linking six phases of accretion to river-mouth reconfigurations and constraining their ages with 14C and OSL dating. The geomorphological and sedimentological reconstruction relied on LiDAR data, coring transects, GPR measurements, grain-size analyses and chemical fingerprinting of volcanic glass and pumice encountered within the beach and dune deposits. We demonstrate that the beach-ridge complex was formed under ample long-term fluvial sediment supply and shorter-term wave- and aeolian modulated sediment reworking. The abundance of fluvially supplied sand is explained by the presence of easily weatherable Los Chocoyos ignimbrites from the ca. 84 ka eruption of Atitlán volcano (Guatemala) in the catchment of the Usumacinta River. Autocyclic processes seem responsible for the formation of ridge/swale couplets. Fluctuations in their periodicity (ranging from 6–19 yrs) are governed by progradation rate, and are therefore not indicative of sea level fluctuations or variability in storm activity. The fine sandy beach ridges are mainly swash built. Ridge elevation, however, is strongly influenced by aeolian accretion during the time the ridge is located next to the beach. Beach-ridge elevation is negatively correlated with progradation rate, which we relate to the variability in sediment supply to the coastal zone, reflecting decadal-scale precipitation changes within the river catchment. In the Southern Mexican delta plain, the coastal beach ridges therefore appear to be excellent recorders of hinterland precipitation.
Automated terrestrial laser scanning with near-real-time change detection – monitoring of the Séchilienne landslide

Published: May 2017

Abstract. We present an automated terrestrial laser scanning (ATLS) system with automatic near-real-time change detection processing. The ATLS system was tested on the Séchilienne landslide in France for a 6-week period with data collected at 30 min intervals. The purpose of developing the system was to fill the gap of high-temporal-resolution TLS monitoring studies of earth surface processes and to offer a cost-effective, light, portable alternative to ground-based interferometric synthetic aperture radar (GB-InSAR) deformation monitoring. During the study, we detected the flux of talus, displacement of the landslide and pre-failure deformation of discrete rockfall events. Additionally, we found the ATLS system to be an effective tool in monitoring landslide and rockfall processes despite missing points due to poor atmospheric conditions or rainfall. Furthermore, such a system has the potential to help us better understand a wide variety of slope processes at high levels of temporal detail.
Spatial and temporal variability of water-filled crevasse hydrologic states along the shear margins of Jakobshavn Isbrae, Greenland
Authors: Joseph Casey A. , Lampkin Derrick J.
Published: May 2017

Abstract. The impact of melt water injection into ice streams over the Greenland Ice Sheet is not well understood. Water-filled crevasses along the shear margins of Jakobshavn Isbræ are known to fill and drain, resulting in weakening of the shear margins due to reduced basal friction. Seasonal variability in the hydrologic dynamics of these features has not been quantified. In this work, we characterize the spatial and temporal variability in the hydrological state (filled or drained) of these water-filled crevasse systems. A fusion of multi-sensor optical satellite imagery was used to examine hydrologic states from 2000 to 2015. The monthly distribution of crevasse systems observed as water filled is unimodal with peak number of filled days during the month of July at 329 days, while May has the least at 15. Over the study period the occurrence of drainage within a given season increases. Inter-seasonal drain frequencies over these systems ranged from 0 to 5. The frequency of multi-drainage events are correlated with warmer seasons and large strain rates. Over the study period, summer temperatures averaged from −1 and 2 °C and tensile strain rates have increased to as high as ~ 1.2 s-1. Intermittent melt water input during hydrofracture drainage responsible for transporting surface water to the bed is largely facilitated by high local tensile stresses. Drainage due to fracture propagation may be increasingly modulated by ocean-induced calving dynamics for the lower elevation ponds. Water-filled crevasses could expand in extent and volume as temperatures increase resulting in regional amplification of ice mass flux into the ice stream system.
Wind field reconstruction from nacelle-mounted lidar short-range measurements
Authors: Borraccino Antoine , Schlipf David , Haizmann Florian , Wagner Rozenn
Published: May 2017

Abstract. Profiling nacelle lidars probe the wind at several heights and several distances upstream of the rotor. The development of such lidar systems is relatively recent, and it is still unclear how to condense the lidar raw measurements into useful wind field characteristics such as speed, direction, vertical and longitudinal gradients (wind shear). In this paper, we demonstrate an innovative method to estimate wind field characteristics using nacelle lidar measurements taken within the induction zone. Model-fitting wind field reconstruction techniques are applied to nacelle lidar measurements taken at multiple distances close to the rotor, where a wind model is combined with a simple induction model. The method allows robust determination of free-stream wind characteristics. The method was applied to experimental data obtained with two different types of nacelle lidar (five-beam Demonstrator and ZephIR Dual Mode). The reconstructed wind speed was within 0.5 % of the wind speed measured with a mast-top-mounted cup anemometer at 2.5 rotor diameters upstream of the turbine. The technique described in this paper overcomes measurement range limitations of the currently available nacelle lidar technology.

Published: May 2017

This paper aims to investigate the effects of perceived ease of use, perceived usefulness, self-efficacy, trust, job opportunity, top management support, competitive pressure, and regulatory support on employees’ behavioral intention to use cloud computing. Data was collected by means of self-administrated questionnaire containing 25 items from 205 employees’ working in three, four, and five star hotels. Multiple regression analysis was conducted to test the research hypotheses. Results of the current study revealed that there are significant impacts of four independent variables (i.e. job opportunity, top management support, competitive pressure, and regulatory support) on behavioral intention (BI) to use cloud computing; whereas four independent variables (i.e. perceived ease of use, perceived usefulness, self-efficacy, and trust) have no significant impact on BI. The results of T-test also showed that there is a significant difference in the impact of BI to use cloud computing in favor of gender. On the other hand, the results of ANOVA’s test showed that there is no significant difference in the impact of BI that can be attributed to age, educational level, and personal income; whereas a significant difference found in favor of work position and hotel’s classification. In light of these findings, implications to both theory and practice are discussed.
Learning styles and intelligence types versus academic performance of nursing students of the University of Zambia
Authors: Katowa-Mukwato Patricia , Chapima Fabian , Nambala-Sianchapa Brenda , Mwiinga-Kalusopa Victoria
Published: May 2017

Background: Learning styles are inherent personal attributes that determine the preferred teaching and learning method(s) for individual while an intelligence type is an individual’s levels of aptitude in various content areas as there is no one individual who is universally intelligent. An understanding of the two concepts is essential for designing suitable teaching approaches.Methods: This was a descriptive correlation study which explored the relationship between two variables; learning styles and intelligence types and academic performance of nursing students enrolled in the conventional nursing program at the University of Zambia. Data on learning styles was collected using the Visual, Auditory, Reading/Writing and Kinesthetic (VARK) questionnaire version 7.8 as proposed by Neil Fleming while Gardner’s questionnaire for assessing multiple intelligences was used to collect data on the students’ intelligence types. Results for the end of 2015/2016 academic year were used to determine academic performance.Results: Almost two thirds 64 (65.4%) of the participants’ academic performance was at credit level, 32 (32.7%) were at pass while only 2 (2%) were meritorious students. Participants had wide-ranging learning styles from unimodal, to bimodal and tri modal styles, although the majority were unimodal learners 81 (82.6%). Among the unimodal learners, majority 35 (35.5%) were kinaesthetic. On the other hand, 37 (37.8%) had logical mathematical intelligence, followed by bodily-Kinaesthetic 27 (27.6%). Both learning styles and intelligence types showed negative correlation and no significant association with academic performance. The Pearson r correlation and level of significance between learning styles and academic performance was -.092 and 0.372 respectively, while that for intelligence types and academic performance were -.027 and 0.790. Of the three demographic variables of age, gender and year of study, only age showed a positive correlation and significant association with academic performance (p = .002, and r = .144).Conclusions: The negative correlation between learning styles and intelligence types and academic performance may be an indication that the teaching methods utilized for nursing students are varied and therefore capable of promoting learning across different styles and intelligence types without necessarily favouring a specific style or type or that there is simply no association between learning styles and intelligence types and academic performance.

Authors: Misetáné Burján Anita
Published: May 2017

We investigate the connection between the "queen of sciences" (mathematics) and the "royal game" (chess) with respect to the development of mathematical problem solving ability in primary school education (classes 1-8, age 7-15) where facultative chess education is present. The records of the 2014 year's entrance exam in mathematics – obligatory for the enrollment to secondary grammar schools in Hungary – are compared for the whole national database and for the results of a group containing chess-player students. The problems in the tests are classified with respect to the competencies needed to solve them. For the evaluation of the results we used standard mathematical statistical methods.

Published: May 2017

Approach to entrepreneurship and strategy of development is the concepts that have attracted the attention of many researchers and managers from the theoretical and practical dimension, and many companies have used these two concepts, and have won a lot of success. In today's world, the entrepreneurship is known as an engine of local, regional and national economic development. (Ahmadpour, 2007) The process of economic development in developed countries reflects the fact that the economy is under the influence of entrepreneurship. In addition, in the current competitive environment, it is an important factor in the development and survival of the companies. Companies that put the entrepreneurial orientation as their policy approach, through the development of flexible resources, they can increase their long-term potential. (Khanka, 2003) Therefore, in this paper, we examine the relationship between development strategy and entrepreneurship dimensions, including innovation, risk-taking, activism, and competitive aggression in the Mellat bank. The research is applied and is done in correlation way. The questionnaire is used to collect data. The statistical population of the study was limited that 261 statistical samples were used in the analysis. The research findings show that entrepreneurship approaches have a strong and positive impact on its development strategy. The Moderating Competitive dynamic has no impact on the relationship between entrepreneurship approach and development strategy. The findings of this study will help decision-makers to be able to know the importance of entrepreneurial approach so that they can decide appropriate policies to create and launch apps. Based on the results obtained, recommendations are provided for statistical population and bank managers.
El análisis de las características de los grupos étnicos africanos en el suburbio de Foshan desde la perspectiva de la movilidad
Authors: Jin Xin , Li Zhigang
Published: May 2017

La movilidad se ha convertido en un término popular en el siglo xxi, al mismo tiempo que el análisis de la formación y las características dinámicas de las comunidades étnicas ha ido cobrando una mayor importancia en las investigaciones recientes. En el presente estudio, se lleva a cabo una comparación entre el colectivo de africanos que residen en las ciudades de Guangzhou y Foshan. El trabajo se realiza desde la perspectiva de la movilidad y de sus comportamientos más destacados. En los contextos económico, social y político chinos, los suburbios étnicos han ido adquiriendo un mayor protagonismo, tanto por las pautas de movilidad que en ellos se desarrollan y en las que cobran una relevancia especial el espacio residencial, el tiempo de viaje y el medio de transporte, como por las características de la población inmigrante que en ellos reside, su identidad, las redes sociales que desarrollan, la fijación de sus establecimientos comerciales, etc. Estamos ante lugares cuya naturaleza es dinámica, compleja y está directamente relacionada con la situación de ilegalidad de los inmigrantes. A lo largo de este artículo, el trabajo de campo desarrollado y la aplicación de metodologías cuantitativas y cualitativas permitirán observar cómo, frente a los cambios que se producen en los contextos económico y político, las nuevas prácticas de movilidad de carácter transnacional y transregional de los migrantes pueden provocar la transformación de las comunidades étnicas tradicionales y el surgimiento de nuevos suburbios étnicos.

Authors: Chai Yanwei , Shen Yue
Published: May 2017

En relación con la rápida suburbanización de las ciudades chinas, la variedad del entorno, los tipos de vivienda y las comunidades sociales que se han formado son cada vez más relevantes. Tomando Pekín como ejemplo, esta investigación ha estudiado su crecimiento espacial durante las últimas décadas, así como el incremento y la modificación de la población, las viviendas, las industrias y las instalaciones comerciales en los suburbios. Las áreas suburbanas entre la cuarta y la sexta carreteras de circunvalación se han convertido en las zonas con mayor desarrollo durante los últimos años. Concretamente, este estudio investigará la movilidad cotidiana en el sector de Shandi-Qinghe, Pekín, basándose en diarios de actividades de sus habitantes y datos de movilidad captados por GPS durante una semana. Se han estudiado los trayectos hacia el trabajo, los espacios donde se hacen las compras y otras acciones de ocio de tres grupos, definidos según el lugar de actividad laboral y residencia. Existen contrastes evidentes en los perfiles socioeconómicos, las rutas de viaje hacia el trabajo y el lugar de compras y de ocio entre esos tres grupos. En suma, el espacio suburbano de Pekín es cada día más complejo y maduro.
To promote child involvement - healthcare professionals’ use of a health-related quality of life assessment tool during paediatric encounters

Background, aims and objectives: Children and healthcare professionals should be provided with easy-to-use tools which could lead to actionable results. There is increasing interest in the use of patient-reported outcomes to aid management of individual care; therefore the use of health-related quality of life (HRQOL) assessments during consultations need to be studied. The aim of this study was to explore how healthcare professionals use a HRQOL assessment tool during paediatric encounters. Methods: A descriptive, explorative design with a qualitative approach based on video-recordings was chosen. Twenty-one video recordings, from 9 different healthcare professionals’ consultations where an assessment tool of HRQOL were used, were analysed by content analysis. Results: The healthcare professionals were using different strategies and when they combined these strategies 3 approaches emerged. The instructing approach was characterized by healthcare professionals giving a summary of the results, leading to children becoming passive bystanders in the encounter. An inviting approach, requesting the children’s perceptions of their situation resulted in the children becoming involved in the conversations. Conclusions: The child’s involvement could be facilitated depending on which approach was being used. When an inviting and engaging approach is used, actions in a non-linear set of interactions was co-produced with the child. The use of an HRQOL assessment tool changed the management during consultations and acted to promote child involvement.
The development and initial validation of an observational tool for measuring patient participation in clinical consultations
Authors: Poulsen Helle , Iversen Else Dalsgaard , Ammentorp Jette
Published: May 2017

Objective: The aim of this study was to further develop and test The Activity Barometer (TAB) as a tool for measuring patient participation in clinical consultations.  Methods: The tool was further developed and tested by double coding 18 audio recordings from consultations between nurses and patients and by qualitative discussions between 3 raters. The raters discussed the face and content validity of the tool and the inter-rater reliability was calculated. To assess the construct validity, it was hypothesised that the tool could be used to expose a difference in the patients’ participation before and after the nurses had participated in communication skills training. This was assessed based on 31 audio recordings.  Results: All of the 3 raters found the items relevant for measuring patient participation. However, to get reliable ratings, an extended guide for coding was necessary. According to the content validity, we found that by taking a treatment-oriented perspective, core components of patient participation were not included in the tool. To capture the whole concept, the coding should be done from a holistic perspective, including the patients’ everyday life. The inter-rater reliability for the total score (0.85), the questions (0.92) and the preferences/concerns (0.6) were all above acceptable thresholds. The construct validation showed that the tool could expose differences in the patients’ participation before and after the nurses had participated in the communication skills training. Conclusion: TAB is a promising tool for measuring patient participation. However, further validation of the tool in a larger sample is recommended prior to its use in research settings.
