Published: June 2016

Background:
Excessive pelvic tilt may be one of the factors leading to instability in total hip arthroplasty (THA), even when the acetabular cup is placed properly. To our knowledge, only a few studies have described late anterior dislocation due to posterior pelvic tilt. We present 3 cases with late anterior dislocations possibly due to posterior pelvic tilt.

Cases Presentations:
Case-1: An 84-years-old woman fell and presented with an anterior dislocation 12-years after THA. Her pelvis had tilted to approximately 30° posteriorly in a supine position. After conservative treatment, she presented with 10 recurrent anterior dislocations. She had thoracolumbar kyphosis due to multiple compression fractures. Revision with anterior placement of an elevated liner and a 32-mm head corrected the dislocation, and no further dislocations occurred.
Case-2: A 78-years-old woman fell and presented with an anterior dislocation 4-years after THA. Her posterior pelvic tilt had increased 23° due to a lumbar compression fracture. Revision by decreasing the cup anteversion was performed, but recurrent posterior dislocations occurred. Owing to her worsened general condition, further treatment was abandoned.
Case-3: A 79-years-old woman twisted her body and presented an anterior dislocation 3-years after THA. After manual reduction and conservative treatment, the dislocation recurred. Her posterior pelvic tilt had increased 16°.

Conclusion:
Although minor trauma triggered the anterior instability in these patients, the underlying pathomechanism existed in the progressive pelvic posterior tilt due to thoracolumbar kyphosis. As longer life expectancy as well as implant survivorship is predicted, attention must be paid to the change of pelvic tilt in elderly patients.

Published: June 2016

OBJECTIVE: To evaluate experiences related to obstetric hemorrhage and suspected abnormal placentation among first year maternal-fetal medicine fellows. STUDY DESIGN: A cross-sectional anonymous survey was administered at the Society for Maternal-Fetal Medicine fellow retreat in March 2013. Fellows were asked about management strategies that reflected both their individual and institutional practices. RESULTS: There was a 56% response rate (55/98). In cases of postpartum hemorrhage due to uterine atony, there was variable use of the uterine tamponade device. The median incremental time for balloon deflation was every 5 hours (IQR = 2–12). Compared to the east coast, fellows from the west coast performed more hysterectomies (mean±SD; 2.9±2.4 vs. 1.2±1.2, p = 0.004). During a peripartum hysterectomy, 29% of fellows used a handheld cautery device such as Ligasure® or Gyrus®. Fifty-six percent responded that their institution never recommend planned delayed hysterectomies for abnormal placental implantation. CONCLUSION: There is wide variation in practice among first year maternal-fetal medicine fellows in management of peripartum hysterectomy and postpartum hemorrhage.
Effects of florivory on plant‐pollinator interactions: Implications for male and female components of plant reproduction
Authors: Carper Adrian L. , Adler Lynn S. , Irwin Rebecca E. 
Published: June 2016

PREMISE OF THE STUDY:Florivory could have direct negative effects on plant fitness due to consumption of floral organs, and indirect effects mediated through changes in traits important to pollination. These effects likely vary with plant sexual system, depending on sex‐ or morph‐specific patterns of damage. We investigated the direct and indirect effects of simulated florivory on male and female components of reproduction in the native, distylous vine Gelsemium sempervirens.METHODS:We crossed floral damage and supplemental pollination treatments in a common garden array and tracked pollinator behavioral responses. We also estimated male function using fluorescent dye as an analog for pollen transfer, and measured both fruit and seed production.KEY RESULTS:The effects of floral damage varied by floral morph, the genus of floral visitor, and the component of reproduction measured. Damage reduced the number of pollinator visits to pin but not thrum plants, and increased the time some pollinators spent per flower in thrum but not pin plants. Flowers of damaged plants transferred more dye particles to recipient plants compared to undamaged plants, but only later in the season when the majority of dye transfer occurred. Damage had no effect on female reproduction.CONCLUSION:These results suggest that florivory can have positive indirect effects on estimated male plant reproduction through changes in different pollinators’ behavior at flowers, but the effects of floral damage vary with male vs. female function. These results underscore the importance of other species’ interactions at flowers in driving pollinator behavior and pollen transfer dynamics.
HELIOSEISMIC IMAGING OF SUPERGRANULATION THROUGHOUT THE SUN’S NEAR-SURFACE SHEAR LAYER
Authors: Greer Benjamin J. , Hindman Bradley W. , Toomre Juri 
Published: June 2016

ABSTRACT
We present measurements of the Sun’s sub-surface convective flows and provide evidence that the pattern of supergranulation is driven at the surface. The pattern subsequently descends slowly throughout the near-surface shear layer in a manner that is inconsistent with a 3D cellular structure. The flow measurements are obtained through the application of a new helioseismic technique based on traditional ring analysis. We measure the flow field over the course of eleven days and perform a correlation analysis between all possible pairs of depths and temporal separations. In congruence with previous studies, we find that the supergranulation pattern remains coherent at the surface for slightly less than two days and the instantaneous surface pattern is imprinted to a depth of 7 Mm. However, these correlation times and depths are deceptive. When we admit a potential time lag in the correlation, we find that peak correlation in the convective flows descends at a rate of 10–40 m s−1 (or equivalently 1–3 Mm per day). Furthermore, the correlation extends throughout all depths of the near-surface shear layer. This pattern-propagation rate is well matched by estimates of the speed of downflows obtained through the anelastic approximation. Direct integration of the measured speed indicates that the supergranulation pattern that first appears at the surface eventually reaches the bottom of the near-surface shear layer a month later. Thus, the downflows have a Rossby radius of deformation equal to the depth of the shear layer and we suggest that this equality may not be coincidental.
A STRINGENT LIMIT ON THE WARM DARK MATTER PARTICLE MASSES FROM THE ABUNDANCE OF z = 6 GALAXIES IN THE HUBBLE FRONTIER FIELDS
Authors: Menci N. , Grazian A. , Castellano M. , Sanchez N. G. 
Published: June 2016

ABSTRACT
We show that the recently measured UV luminosity functions of ultra-faint lensed galaxies at z ≈ 6 in the Hubble Frontier Fields provide an unprecedented probe for the mass m
X of the warm dark matter (WDM) candidates independent of baryonic physics. Comparing the measured abundance of the faintest galaxies with the maximum number density of dark matter halos in WDM cosmologies sets a robust limit of m
X ≥ 2.9 keV for the mass of thermal relic WDM particles at a 1σ confidence level, m
X ≥ 2.4 keV at 2σ, and m
X ≥ 2.1 keV at 3σ. These constraints are independent of the baryonic physics involved in galaxy formation and constitute the tightest constraints on WDM particle mass derived to date. We discuss the impact of our results on the production mechanism of sterile neutrinos. In particular, if sterile neutrinos are responsible for the 3.5 keV line reported in observations of X-ray clusters, our results firmly rule out the Dodelson–Widrow production mechanism and yield m
sterile ≳ 6.1 keV for sterile neutrinos produced via the Shi–Fuller mechanism.
L’influence du patient sur le travail des soignants et le dialogue social à l’hôpital
Authors: Havard Christelle , Naschberger Christine 
Published: June 2016

Les organisations hospitalières françaises ont connu depuis une décennie de nombreux changements. Ceux-ci ont souvent été justifiés par le souhait d’une plus grande efficacité économique, mais également par la volonté de mieux servir les patients. La place et le rôle des acteurs ont été significativement redéfinis et ont contribué à transformer certaines modalités du travail des personnels hospitaliers. Mais peu de recherches analysent ces changements à partir de l’influence du patient. Cet article propose d’analyser la manière dont la présence du patient et sa représentation à l’hôpital modifient le travail des personnels soignants et les modalités du dialogue social. L’analyse s’appuie sur une grille de lecture articulée autour de deux cadres théoriques : la triangulation des relations de travail et la régulation sociale de Reynaud. Une étude de cas exploratoire menée auprès d’un établissement hospitalier confirme l’impact du patient sur le travail du personnel soignant analysé par la littérature, et met en évidence les régulations qui s’opèrent, au niveau opérationnel, entre les acteurs et par l’encadrement. Cette étude montre également qu’au niveau de la gouvernance, les représentants des usagers font progressivement leur place mais que le dialogue social entre les acteurs s’instaure difficilement au-delà des relations bilatérales.
Les non-réponses sont-elles des reponses ?
Authors: Brasseur Martine , Lacroux Alain , Magnien Laurent 
Published: June 2016

L’étude présentée cherche à comprendre le phénomène des non-réponses à un questionnaire d’appréciation conçu et mis en place ponctuellement dans les organisations dans une optique de soutien au développement des compétences des salariés et à leur apprentissage organisationnel. Une analyse quantitative exploratoire a été menée. Elle a consisté à exploiter statistiquement les données recueillies dans le cadre d’un dispositif de type 360˚ Feed-Back auprès de 1 873 salariés s’autoévaluant ou évalués par leurs collègues, leurs responsables ou leurs managés, représentant 17 176 salariés de leur entourage professionnel. L’étude s’est focalisée sur la population des répondants ayant laissé au moins une valeur manquante dans le questionnaire. Ils représentaient une base de 11 202 répondants, soit 58,81 % des salariés concernés, répartis dans 183 entreprises différentes. Les résultats de l’analyse des données nous ont conduits d’une part à confirmer que ces non-réponses ne sont pas dues au hasard, et d’autre part à considérer qu’elles sont porteuses de sens et qu’elles peuvent être pour partie nécessaires au développement des compétences professionnelles et l’apprentissage organisationnel.
Comprendre les interactions entre scripts de carriere et action individuelle : le cas du secteur humanitaire
Authors: Garbe Emmanuelle , Cadin Loïc 
Published: June 2016

Bien que prometteur en termes de perspectives de recherche, le concept de script de carrière fait l’objet de nombreuses critiques dans le champ des carrières. Il est jugé trop théorique et difficile à opérationnaliser dans le cadre de recherches empiriques. Ce papier propose de répondre à cette critique. Il revient sur les travaux fondateurs du concept et montre que le concept de script de carrière peut être raffiné. Plus particulièrement, il met en évidence deux caractéristiques des scripts de carrière utiles à leur opérationnalisation : leur double dimension cognitive et comportementale et la distinction entre scripts forts et scripts faibles. Il mobilise ensuite ces éléments pour étudier empiriquement, dans le cadre d’une étude menée dans le secteur humanitaire français, la relation existante entre scripts de carrière et action individuelle. Il montre que tous les scripts de carrière n’ont pas la même capacité à guider l’action individuelle, ce qui laisse une marge de manœuvre plus ou moins importante aux individus pour agir et transformer leur script de carrière. Il montre, par ailleurs, que la transformation des scripts de carrière demande un travail cognitif important qui pousse certains individus à changer de script plutôt que de transformer celui qu’ils mobilisent déjà.
La gouvernance des villes intelligentes. Analyse de la littérature sur la gouvernance urbaine intelligente
Authors: Meijer Albert , Rodríguez Bolívar Manuel Pedro 
Published: June 2016

L’intérêt des universitaires pour les villes intelligentes et leur gouvernance connaît une croissance rapide, mais la fragmentation dans les approches adoptées complique le débat. Le présent article a pour but de structurer le débat en analysant un recueil de 51 publications et en observant la variation. L’analyse indique que les publications varient dans l’importance accordée (1) aux technologies intelligentes, au personnel intelligent ou à la collaboration intelligente en tant que caractéristiques des villes intelligentes, (2) la perspective transformatrice ou progressive en ce qui concerne les évolutions dans la gouvernance urbaine, (3) l’amélioration des résultats ou un processus plus ouvert pour revendiquer la légitimité de la gouvernance des villes intelligentes. Nous plaidons en faveur d’une perspective globale : la gouvernance des villes intelligentes consiste à imaginer de nouvelles formes de collaboration humaine en recourant aux TIC pour obtenir de meilleurs résultats et des processus de gouvernance plus ouverts. Les recherches sur la gouvernance des villes intelligentes pourraient s’inspirer des études réalisées sur les facteurs de réussite et d’échec en matière de gouvernement électronique et s’appuyer sur les théories sophistiquées en matière d’évolution socio-technologique. Dans le présent article, nous verrons que la gouvernance des villes intelligentes n’est pas une question technologique : la gouvernance des villes intelligentes doit être étudiée comme un processus complexe de changement institutionnel et prendre en considération la nature politique des visions séduisantes de la gouvernance socio-technologique. Remarques à l’intention des praticiens Notre étude permettra aux praticiens de comprendre de manière approfondie les débats actuels à propos de la gouvernance des villes intelligentes. Nous verrons que la gouvernance des villes intelligentes consiste à imaginer de nouvelles formes de collaboration humaine en recourant aux technologies de l’information et de la communication. Les directeurs municipaux doivent bien comprendre que la technologie en soi ne va pas rendre la ville plus intelligente : la construction d’une ville intelligente passe par la compréhension politique de la technologie, une approche processus pour gérer la ville intelligente émergente et une prise en considération des gains économiques et autres valeurs publiques.
Identifying Kittlitz's Murrelet Nesting Habitat in North America at the Landscape Scale
Authors: Felis Jonathan J. , Kissling Michelle L. , Kaler Robb S.A. , Kenney Leah A. , Lawonn Matthew J. 
Published: June 2016

AbstractThe Kittlitz's murrelet Brachyramphus brevirostris is a small, noncolonial seabird endemic to marine waters of Alaska and eastern Russia that may have experienced significant population decline in recent decades, in part because of low reproductive success and terrestrial threats. Although recent studies have shed new light on Kittlitz's murrelet nesting habitat in a few discrete areas, the location and extent of suitable nesting habitat throughout most of its range remains unclear. Here, we have compiled all existing nest records and locations to identify landscape-scale parameters (distance to coast, elevation, slope, and land cover) that provide potential nesting habitat in four regions: northern Alaska, Aleutian Islands, Alaska Peninsula Mountains and Kodiak Island, and Pacific Coastal Mountains (including nearshore interior Canada). We produced a final map classifying 12% (70,411 km2) of the lands assessed as potential Kittlitz's murrelet nesting habitat, with dense but distinct patches in northern Alaska and a more uninterrupted, narrow band extending across the Pacific Coastal Mountains, Alaska Peninsula Mountains, and Aleutian Islands. The extent of habitat-capable parameter values varied regionally, indicating that the Kittlitz's murrelet may be able to use a variety of habitats for nesting, depending on availability. Future nesting habitat studies could employ spatially random sampling designs to allow for quantitatively robust modeling of nesting habitat and predictive extrapolation to areas where nests have not been located but likely exist.
Dignity and work: global market and self-sustenance
Authors: Venter J.J. 
Published: June 2016

It is argued here that market fundamentalistic theories ignore the issue of human agency in work, and the different types of work, because – focussing on the market mechanism, supply, demand, and price - they have lost track of that which economic activities (work) are intended for, namely self-sustenance. They have also minimised human agency in the economic theory, and therefore the understanding of being-human is lost from both economic theory and practice. Thus they cannot explicate the role of work for the individual and the community – namely care for self and others – the significance quality work as part of human dignity is forgotten. I am arguing for a restoring of meaningful self-sustenance as the norm for work, and the recognition of the dignifying role of such self-sustenance – both for the community and the individual.
How to make sense of the past – salient issues of Metahistory
Authors: Rusen Jorn 
Published: June 2016

This aerticle provides an overview of current issues in metahistoty. Basic categories of historical thinking, such as memory and historical culture, or historical consciousness, are outlined and contextualised in the field of historical studies. The leading question adresses the process of historical sense generation and its fundamental principles and criteria. In respnse to the traumatic historical experiences of crimes against humanitiy in the 20th century two culturally established procedures of sense generation are applied to historical thinking: mourning and forgiving. The author tries to widen the horizon of historical thinking into the dimension of intercultural communication. In the process he responds to the challenge of globilization. There is an accent on the need to pursue new approaches in history.
‘When we are tired we shall rest’: bus boycotts in the United States of America and South Africa and prospects for comparative history
Authors: Catsam Derek Charles 
Published: June 2016

This article looks at some of the practical, methodological, and disciplinary issues connected to comparative and transnational history through the lens of bus boycotts in South Africa and the United States in the 1950s. Comparative history by its very nature requires historians to transcend both the restrictive boundaries that the profession sometimes imposes as well as a fundamentally interdisciplinary approach to scholarship. Yet as the suggestive comparisons between boycotts in Montgomery, Alabama, Baton Rouge, Louisiana, and the Transvaal in the mid-1950s show, such work can be rewarding in providing a transnational framework for understanding protest movements that transcend national borders. Catsam argues in the end of his article that “a deeper understanding of both [the American and South African] struggles together may well help us better to grasp the significance of each separately.”
Transdisciplinary research in the cooperation between intercultural philosophy and empirical sciences
Authors: Kimmerle Heinz 
Published: June 2016

This article will examine how philosophy and empirical sciences can cooperate in research. It is presupposed that in philosophy and in the empirical sciences different types of discourses are used. This difference causes a large gap between them, which has to be bridged. Intercultural philosophy is understood as a specific approach to philosophy as a whole. It is necessary to make philosophy fit into a world in which exchanges are happening on a global level in many fields. In the dialogues between the philosophies of different cultures, support is needed from certain empirical sciences for the understanding of the philosophy, which is based on the the participation of philosophers in everyday life and everyday language. Therefore, in addition to the the support by empirical sciences, living in a foreign culture, participating in its life, is necessary for intercultural philosophers.
HIV/AIDS awareness among first year pharmacy students and the role of the university
Authors: Bezuidenhout Selente , Summers Rob 
Published: June 2016

As HIV/AIDS continues to spread and affect the lives of millions of people, a sense of urgency has developed about the imperative need to stop the epidemic. Education is the key to change knowledge, attitudes and behaviour. There is currently a gap in educationprogrammes targeting youths of ages 18-24 years, for example, those enrolled in tertiary institutions. The aim of the study was therefore to establish the level of HIV/AIDS awareness among undergraduate pharmacy students at the University of Limpopo (Medunsa Campus)/ Tshwane University of Technology Schools of Pharmacy. A structured questionnaire was administered to pharmacy students on entry to the programme. Although the students of 2003, 2004 and 2005 obtained mean percentage HIV/AIDS awareness scores in the range of 70%-80%, they had inadequate knowledge of some transmission routes, events that occur when HIV invades the body, the “window period” and some symptoms. These knowledge gaps should be addressed by universities by integrating HIV/AIDS policies and education fully into all aspects of their planning, operations andteaching.
Thinking processes used by high-performing students in a computer programming task
Authors: Havenga Marietjie , De Villiers R , Mentz E 
Published: June 2016

Computer programmers must be able to understand programming source code and write programs that execute complex tasks to solve real-world problems. This article is a trans- disciplinary study at the intersection of computer programming, education and psychology. It outlines the role of mental processes in the process of programming and indicates how successful thinking processes can support computer science students in writing correct and well-defined programs. A mixed methods approach was used to better understand the thinking activities and programming processes of participating students. Data collection involved both computer programs and students’ reflective thinking processes recorded in their journals. This enabled analysis of psychological dimensions of participants’ thinking processes and their problem-solving activities as they considered a programming problem. Findings indicate that the cognitive, reflective and psychological processes used by high-performing programmers contributed to their success in solving a complex programming problem. Based on the thinking processes of high performers, we propose a model of integrated thinking processes, which can support computer programming students.Keywords: Computer programming, education, mixed methods research, thinking processes.
