Published: June 2018

BackgroundAn additional portfolio role GPs can take on is as an appraiser. Whilst clinical and education roles are well-defined, less is known about how appraisers learn the skills to appraise and develop their own repertoire of practice.AimParticipating in groups can be a way of learning and improving professional practice. This study uses insights from ‘communities of practice’ (COP) as a way of understanding an under-explored aspect of the development of appraisers.MethodIn-depth interviews with appraisers (both new and long established i.e. ‘lead appraisers’) were analysed using Saldana’s (2016) approach2 to coding and interpretation of qualitative data. The methodology foregrounds constructivist interpretation based on a theory of learning that situates learning within the social milieu of practice and a view of the world as socially constructed. The researchers’ part in this process is to make interpretations through engagement with data.ResultsCOP is used as a conceptual framework drawing on ‘mutual engagement’, ‘joint enterprise’ and ‘shared repertoire’ as a priori codes.3 The setting is a country where a system of appraisal was introduced in 2009 and prior to this there was no formal system. Studying appraisers in a new, unfamiliar setting makes learning more apparent.ConclusionThis study is part of on-going work looking at the role of the medical appraiser. The paper draws out implications for the development of this new professional group.

Abstract
We analyze the binary gravitational microlensing event OGLE-2017-BLG-1130 (mass ratio q ∼ 0.45), the first published case in which the binary anomaly was detected only by the Spitzer
Space Telescope. This event provides strong evidence that some binary signals can be missed by observations from the ground alone but detected by Spitzer. We therefore invert the normal procedure, first finding the lens parameters by fitting the space-based data and then measuring the microlensing parallax using ground-based observations. We also show that the normal four-fold space-based degeneracy in the single-lens case can become a weak eight-fold degeneracy in binary-lens events. Although this degeneracy is resolved in event OGLE-2017-BLG-1130, it might persist in other events.
Frequency-dependent Alfvén-wave Propagation in the Solar Wind: Onset and Suppression of Parametric Decay Instability
Authors: Shoda Munehito , Yokoyama Takaaki , Suzuki Takeru K. 
Published: June 2018

Abstract
Using numerical simulations we investigate the onset and suppression of parametric decay instability (PDI) in the solar wind, focusing on the suppression effect by the wind acceleration and expansion. Wave propagation and dissipation from the coronal base to 1 au is solved numerically in a self-consistent manner; we take into account the feedback of wave energy and pressure in the background. Monochromatic waves with various injection frequencies, f
0, are injected to discuss the suppression of PDI, while broadband waves are applied to compare the numerical results with observation. We find that high-frequency (

) Alfvén waves are subject to PDI. Meanwhile, the maximum growth rate of the PDI of low-frequency (

) Alfvén waves becomes negative due to acceleration and expansion effects. Medium-frequency (

) Alfvén waves have a positive growth rate but do not show the signature of PDI up to 1 au because the growth rate is too small. The medium-frequency waves experience neither PDI nor reflection so they propagate through the solar wind most efficiently. The solar wind is shown to possess a frequency-filtering mechanism with respect to Alfvén waves. The simulations with broadband waves indicate that the observed trend of the density fluctuation is well explained by the evolution of PDI while the observed cross-helicity evolution is in agreement with low-frequency wave propagation.
Citoyenneté, santé mentale, inclusion, territoire
Authors: Botbol Michel 
Published: June 2018

Comme beaucoup d’entre vous le savent car ils ont été les acteurs ou les témoins assidus de nombreux débats à ce sujet, la notion de santé mentale (SM) est, en France peut être plus qu’ailleurs, au centre d’une controverse qui oppose une version « psychiatro-centrique » à une version « psychiatrofuge » de cette notion.
Co-construction et synergies de la communication en ligne : analyse des pratiques d’utilisation de LinkedIn appliquée au secteur automobile
Authors: Fueyo Céline 
Published: June 2018

Cette recherche mesure la crédibilité perçue de deux types de médias qui génèrent des interactions entre l’entreprise et les parties prenantes sur les réseaux sociaux professionnels : d’une part, les médias possédés représentés par les Pages Entreprises LinkedIn (PEL) et, d’autre part, les médias gagnés représentés par les Pages Personnelles LinkedIn (PPL). Nous analysons ainsi la crédibilité de la communication d’entreprise en ligne et celle de la communication interpersonnelle en ligne des employés ; puis nous menons une étude comparative. Ces mesures de la crédibilité perçue sont réalisées auprès d’un échantillon de 1 500 répondants qualifiés de nationalité française. L’objectif de cette recherche est d’évaluer, dans un environnement numérique, la crédibilité accordée à chacun de ces deux médias, afin d’émettre des recommandations stratégiques qui permettront à l’entreprise de s’adapter aux nouvelles pratiques en ce qui concerne sa relation avec les parties prenantes externes. Les résultats obtenus démontrent que les médias gagnés issus des employés sont plébiscités. C’est un élément majeur à prendre en compte dans la stratégie de communication des entreprises. L’utilisation simultanée des deux modes de communication aboutit à de la création de valeur pour l’entreprise et ses employés qui bénéficieront de la croissance induite par la synergie.
Vers une échelle de mesure de l’ancrage territorial des filiales étrangères
Authors: Serval Sarah 
Published: June 2018

Les manageurs territoriaux font de l’ancrage territorial des filiales étrangères un objectif stratégique pour pérenniser l’attractivité de leur territoire. En ce sens, il ne s’agit pas seulement d’attirer, mais aussi de retenir les filiales étrangères une fois celles-ci implantées. Pour autant, le concept d’ancrage territorial, en tant qu’objet de management territorial, reste peu étudié dans la littérature académique. Quelles en sont ses dimensions ? Comment apprécier le niveau d’ancrage d’une filiale étrangère à l’autre ? Il s’agit ici d’une première étape dans la conceptualisation d’une théorie de l’ancrage territorial des filiales étrangères afin de favoriser l’attractivité durable des territoires. Les résultats de la recherche menée, à travers l’étude du cas de l’Alsace, révèlent une échelle de mesure à trois dimensions cumulatives et graduelles : spatiale, réticulaire et téléologique. Les résultats mettent également en lumière la complexité du phénomène d’ancrage en ce qu’il résulte d’une tension permanente entre proximité et distance.
La stratégie, concept culturel ? Exploration de choix organisationnels par les imaginaires stratégiques de dirigeants de multinationales émergentes
Authors: Marchand Morgan 
Published: June 2018

Cet article s’intéresse à l’influence des imaginaires stratégiques sur les décisions organisationnelles. En prenant appui sur l’analyse des types d’intégration mis en œuvre par 25 Multinationales de Pays Emergents (EMNE), pour donner suite à des acquisitions d’entreprises françaises, ce travail cherche à questionner l’effet du pays d’origine sur ces choix stratégiques. Il en explore les effets sous l’angle de l’influence des héritages administratifs des EMNE, et plus précisément des imaginaires stratégiques et politiques de leurs dirigeants. Ce faisant, il corrobore la vision de la stratégie comme un concept « profondément culturel ».

Who owns and is responsible for the elephant in the room? Management plans for free-roaming elephant in South Africa
Authors: Blackmore Andrew C. , Trouwborst Arie 
Published: June 2018

In 2008, South Africa adopted its ‘National Norms and Standards for the Management of Elephants in South Africa’. Concern has subsequently been raised as to whether these norms and standards apply to free-ranging elephant on land, which had not been enclosed with a fence with the express purpose of containing these animals and other game on the property. The application of these norms and standards pivots on whether the owner(s) of the property have taken possession of these animals in accordance with common law applicable to game, or have given effect to the provisions of the Game Theft Act. To address this concern, this article briefly explores the evolution of South African regulatory jurisprudence applicable to game, including elephant, and analyses the norms and standards in relation to international and national legislation and common law applying to elephants. The norms and standards are not applicable to unowned, free-roaming elephant. These norms and standards, therefore, do not fulfil their primary objective of uniform management of elephant across South Africa. This limitation of the norms and standards, therefore, needs to be considered when they are revised.
God becomes beautiful … in mathematics
Authors: Kessler Volker 
Published: June 2018

This article is transdisciplinary in that it touches on the disciplines of both mathematics and theology. It is about the mysterious link between truth and beauty in mathematics. It uses the theological pattern laid by the practical theologian Bohren in his book, God’s Becoming Beautiful. Mathematics can be seen as science or art. I argue that in both cases, we could conclude that God becomes beautiful in mathematics. This leads to the observation that there is some spirituality in mathematics. This insight might also have practical implications for mathematics education in schools.
Investigating teacher learning from a university programme for Foundation Phase teachers
Authors: Mukeredzi Tabitha G. , Bertram Carol , Christiansen Iben 
Published: June 2018

Background: There is a growing focus in South Africa on teachers developing appropriate knowledge, skills and dispositions for teaching to support young learners’ development and learning. One such teacher development programme is the Advanced Certificate in Teaching for Foundation Phase teachers, offered by the University of KwaZulu-Natal (UKZN). This research sought to establish the learning of this sample of teachers as this was the first time the programme was offered at this level in South Africa and in UKZN. Aim: The study investigated the knowledge the teachers said they gained, how they acquired it and ways in which they said learning improved their classroom practices. Methods: This was a qualitative study. Data were generated from 26 participants through two rounds of focus group interviews in June 2013 and in November 2014. Data were analysed thematically using concepts of accommodation or assimilation, and practical or conceptual knowledge. Results: Respondents’ statements indicated development of a range of practical knowledge about planning and teaching strategies, and conceptual knowledge like child development, creative play, circle of courage and others. Teachers also reported ways in which their classroom practices had improved. However, both institution- and student-related learning barriers emerged during the first semester around programme demands and poor curriculum delivery. Conclusion: Respondents reported more about acquiring practical than conceptual knowledge and having improved practices in many ways. Participants also reported gaining conceptual knowledge around child development, circle of courage, and learning barriers. They acquired these kinds of knowledge through both assimilation and accommodation.
An archival review of preferred methods for theory building in follower research
Authors: Feldman Joseph A. 
Published: June 2018

Aim: The purpose of this research was to delineate methodological trends in articles published both internationally and locally that will reveal the extent of new theory building. Setting: The research strategy and methodology examined trends in theory building over a 52-year period (1962–2014). Method: An archival review of the published literature was conducted and each article was examined to identify the general research method employed. The chi-square test was used to determine whether there is a significant difference between the expected frequencies and the observed frequencies in one or more of four categories. Results: The archival data indicate that articles published over the past 52 years in major international and South African journals are skewed towards quantitative and conceptual research. This implies that researchers in leadership studies employed qualitative and mixed methodologies in their work less often than quantitative and conceptual methodologies. Conclusion: This trend has implications for the development of leadership-followership research. Research methods should be used with mindfulness, with qualitative methods being used to observe social and human problems, followed by quantitative methods to test inductively formulated followership theories. It is particularly important, in the context of diverse cultures, to note that local attempts to formulate authentic theory development will remain difficult and unsuccessful until endogenous management systems are established and institutionalised. This is very important for scholars who believe that an affinity for qualitative methodology affords the opportunity for emic research rather than merely for testing theories and constructs that may not capture local followership phenomena.
The impact of team dialogue sessions on employee engagement in an information and communication technology company
Authors: Seymour Michael A.W. , Geldenhuys Dirk J. 
Published: June 2018

Orientation: Engaged employees are regarded as extremely valuable in today’s unstable economic environment. However, despite spending large amounts of money on the improvement of employee engagement, the effect thereof is seldom determined. This study was about determining the impact of team dialogue sessions on the enhancement of employee engagement in a large information and communication technology company over a 2-year period.Research purpose: This study focused on determining the improvement of employee engagement through an organisation development intervention. The intervention was based on a social constructionist perspective, namely, team dialoguing, and was facilitated over a period of two years.Motivation for the study: Although the matter regarding the improvement of employee engagement seems to be extensively discussed in the literature, research on the use of interventions to enhance employee engagement is to a large extent still lacking. Based on a theoretical integration, it was argued that team dialoguing could improve employee engagement.Research design, approach and method: This was a quantitative study, employing a quasi-experimental design. An experimental group was exposed to an organisation development intervention of team dialogues over a 2-year period and then compared to a control group that had not been exposed to the intervention.Main findings: Although with a small effect size, it was discovered that facilitating team dialogue sessions had a positive impact on employee engagement, more specifically on the exercise of discretionary effort, intention to remain, rational commitment, communication and supervisory support as dimensions.Practical and managerial implications: The practical implication of this study is that the engagement of employees can be enhanced by involving the direct supervisor and his or her team in dialoguing sessions.Contribution or value-add: The study contributed to the literature on employee engagement by reporting on the implementation of an intervention over a period of two years to enhance employee engagement.
Prevalence, severity, and request for treatment of dental fluorosis among adults in an endemic region of Northern Nigeria
Authors: Idon Paul Ikhodaro , Enabulele Joan Emien 
Published: June 2018

ABSTRACTObjectives: The objective was to assess the prevalence of all forms of dental fluorosis (DF), the severity, and the request for treatment as a measure of the burden of the condition among adult patients seen at a tertiary health facility in an endemic region of Northeastern Nigeria. Materials and Methods: This was a cross-sectional study that collected required information using a questionnaire from adult dental patients followed by dental examination to assess for DF. Statistical Analysis Used: Associations between sociodemographic distributions (age and gender) and prevalence were analyzed on the Statistical Package for the Social Sciences using the Chi-square test. Analysis was done at 95% confidence interval and the level of statistical significance was set at P < 0.05. Results: Three hundred and twelve patients (41.7%) were diagnosed with DF among the patients who resided in the endemic region with a calculated Community Fluorosis Index of 0.62. The mean age of the affected patients was 33.8 ± 9.2 years, with a majority of the patients in the 16–25 (47.4%) years' age group and a preponderance among females (P = 0.003). A greater proportion of the 312 diagnosed patients, 201 (64.3%), had fluorosis of esthetic concern, while only 9.3% sought treatment. Most of these patients that sought treatment had the severe form of the enamel defect. Conclusions: DF should be considered as a condition of public health importance in this region. It is necessary to conduct a community-based study and fluoride mapping of the northeastern region as well to determine other factors that may contribute to its occurrence in this population.

ABSTRACT
Objective: The objective is to study the effect of obesity on dental caries among schoolchildren in Sharjah, United Arab Emirates. Materials and Methods: The sample comprised 803, 11–17-year-old schoolchildren. The study was in the form of a randomized cross-sectional manner. Method used was two questioners. The first assessed socioeconomic and general health and the second detailed their demographic, oral hygiene, and dietary habits. Dental examination included dental caries assessment using the World Health Organization 1997 criteria and gingival health valuation. Clinical examination consisted of height, weight, and body mass index (BMI). Data analysis was done by descriptive, univariate, and multiple regressions. Results: In this sample, 75% had dental caries and the mean decayed, missing, and filled teeth (DMFT) was 3.19 (standard deviation: 2.9). Obesity was seen in 15% of the adolescents and the mean BMI was 21. The link between DMFT and BMI, when evaluated using univariate analysis, showed a significant correlation (r = 0.097, P = 0.006), indicating that the rise in BMI by 10 points resulted in an increase in DMFT by 0.57. However, in the multivariate analysis, a significant relationship was observed only between father's education (P < 0.001), adolescent's age (P < 0.001), gender (P = 0.008), ethnicity (P = 0.001), and soft drink consumption with DMFT while BMI showed a significant association with age (P < 0.001), school fees (P = 0.005), obesity in family (P < 0.001), and soft drink consumption (P < 0.001). Conclusions: Obesity and dental caries were not significantly associated. The most important predictor for obesity and dental caries was soft drink consumption.
Different treatment approaches for the localized gingival overgrowths: Case series
Authors: Ozener Hafize Ozturk , Kundak Kubra , Sipahi Nimet Gul , Yetis Ece , Dogan Basak 
Published: June 2018

ABSTRACTLocalized gingival overgrowths belong to a common group of lesions designated as focal reactive overgrowths. They occur in response to chronic, low‑grade irritation caused by plaque or any other irritant. They have multifactorial etiopathology but exhibit similar clinical features with slight variations in patient complaints. Success of the lesions’ management depends on formation of healthy contours of the surgical area after excision of lesion and absence of a recurrence. The purpose of case series is to present 6 different cases of localized gingival overgrowths and their management with the following techniques: nonsurgical periodontal treatment, gingivectomy, flap surgery, free gingival graft, gingival unit, and connective tissue graft.
Fracture resistance of veneers in premolars

Published: June 2018

ABSTRACT
Objective: The purpose of the study was to compare the fracture resistance of ceramic veneers and composite resin veneers with and without dental preparation. Materials and Methods: Forty freshly extracted mandibular premolars were selected and randomly assigned into four groups (n = 10): Group NPR = no dental preparation and direct veneer with 0.2 mm thick composite resin (Amelogen Plus, Ultradent); Group NPC = no dental preparation and 0.2 mm thick lithium disilicate ceramic veneer (IPS e.max Press, Ivoclar Vivadent); Group P2C = Tooth preparation of 0.2 mm and 0.2 mm thick ceramic veneer (IPS e.max Press); and Group P5C = Tooth preparation of 0.5 mm and 0.5 mm-thick ceramic veneer (IPS e.max Press). In all groups, the restorations covered 1 mm of the occlusal surface of the buccal cusp, and the thickness of this area was the same of the buccal area (0.2 mm or 0.5 mm). After the luting procedure, all groups were thermocycled (10,000 cycles, 5°C–55°C) and subjected to fracture resistance test under compression (Instron 4444 with a crosshead speed of 0.5 mm/min). The mode of failure analysis was performed under a ×10 magnification. Data were subjected to one-way ANOVA and Duncan's post hoc test (P < 0.05). Results: The mean fracture resistance (men ± standard deviation) was NPR = 690.33 ± 233, NPC = 790.52 ± 408, P2C = 1131.34 ± 341, and P5C = 983.56 ± 202. There were significant differences of the fracture resistance values between all groups (P = 0.013). NPR and NPC groups showed mean values of fracture resistance significantly lower than P2C. However, P5C presented intermediate values without a significant difference from the other groups. The mode of failure for all groups was mixed (60%), cohesive failures (20%), root failures (15%), and adhesive failures (5%). Conclusion: Minimally invasive tooth preparation (0.2-mm) allowed to achieve higher fracture resistance in premolars restored with lithium disilicate ceramic veneers. Attention should be given to the 0.5 mm preparation since catastrophic fractures only happened when this preparation depth was performed.
