Published: July 2018

Purpose: Rural and remote Saskatchewan has a shortage of physiotherapists. Positive student experiences in rural and remote communities may influence whether graduates choose to work in these settings. The intention of the first full-time, 4-week clinical placement (CP) in the Master of Physical Therapy programme at the University of Saskatchewan is to provide clinical experiences in rural settings outside Saskatoon and Regina. This study examines the geographic distribution of and yearly variation in these CPs to determine whether this stated intent is being realized. Method: We analyzed the locations of physiotherapy student CPs from 2008 to 2016 using geospatial mapping. Results: Spatial patterning using mapping identified variability in the number of rural placements in geographical regions in Saskatchewan over a 9-year period. An average of 75% of CP experiences occurred in rural locations outside the two major cities in Saskatchewan between 2008 and 2016 (ranging from 58% in 2015 to 84% in 2009). Conclusions: The goal of providing all University of Saskatchewan physiotherapy students with a rural experience for their first CP is not being met. Securing more CPs in rural settings may have a positive impact on recruitment of physiotherapists to these communities.
Trigger Point Sensitivity Is a Differentiating Factor between Cervicogenic and Non-Cervicogenic Headaches: A Cross-Sectional, Descriptive Study
Authors: Olivier Benita , Pramod Abraham , Maleka Douglas
Published: July 2018

Purpose: A common factor in all forms of headache is the presence of myofascial trigger points (TrPs). The aim of this study was to compare the presentation of patients with cervicogenic headaches and patients with non-cervicogenic headaches in the sensitivity of TrPs in their upper trapezius, sternocleidomastoid, temporalis, and posterior cervical muscles. Method: This was a descriptive, cross-sectional study. The following variables were compared between patients with cervicogenic (n=20) and patients with non-cervicogenic (n=20) headaches: sensitivity (pain-pressure threshold) of TrPs in the upper trapezius, sternocleidomastoid, posterior cervical, and temporalis muscles (using a handheld, digital algometer); level of disability (using the Henry Ford Hospital Headache Disability Inventory questionnaire); demographics (age, sex); anthropometrics (BMI); and clinical presentation (duration and intensity of symptoms). The independent Student t-test and χ2 test were used to determine the differences between the two groups. Effect sizes (Cohen's d) were calculated when relevant. Results: The two groups were similar in level of disability, demographic and anthropometric data, and clinical presentation. However, TrP sensitivity in the right upper trapezius (p=0.006; Cohen's d=0.96) and the left upper trapezius (p=0.003; Cohen's d=1.06) muscles was higher in the cervicogenic group. Conclusions: Increased sensitivity of TrPs in the upper trapezius muscle may be used as a differentiating factor in the diagnosis of cervicogenic headaches. This finding emphasizes the importance of integrating this muscle into the rehabilitation programs of patients with cervicogenic headache.

Authors: Hermaren Vinna , Achyar Adrian
Published: July 2018

The purpose of this paper is to investigate social media communication and its impact on customer-based brand equity. Compare two social media communication tools that are firm created content and user generated content. A total of 114 data sets developed through a standard online survey to investigate the impact of firm created content and user-generated content evaluation in social media on brand awareness / association, perceived quality and brand loyalty to the cosmetics industry in Indonesia. A mini survey was conducted to find out the types of cosmetic brands that do not perform ad campaigns in traditional media such as television to see clearly the influence of brand communication in social media against brand awareness and association. The author applies Structural Equation Modeling (SEM) techniques to investigate the effect of communication on social media on customer-based brand equity. The findings of this study indicate that evaluation of firm created content has a positive and significant impact on brand association / awareness, perceived quality and brand loyalty. Meanwhile, evaluation of user-generated content has significant effect only on brand awareness / association and perceived quality. In the dimensions of customer-based brand equity, only perceived quality is significantly influenced by brand awareness / association. This research is relevant for marketers for the development of corporate strategy, especially in the cosmetics industry that uses social media as a medium of communication to customers.

Authors: Slegers Antoine , Filiou Renée-Pier , Montembeault Maxime , Brambati Simona Maria
Published: July 2018

The language changes that occur over the course of Alzheimer’s disease (AD) can impact communication abilities and have profound functional consequences. Picture description tasks can be used to approximate everyday communication abilities of AD patients. As various methods and variables have been studied over the years, current knowledge about the most affected features of AD discourse in the context of picture descriptions is difficult to summarize. This systematic review aims to provide researchers with an overview of the most common areas of impairment in AD discourse as they appear in picture description tasks. Based on the 44 articles fulfilling inclusion criteria, our findings reflect a multidimensional pattern of changes in the production (speech rate), syntactic (length of utterance), lexical (word-frequency and use of pronouns), fluency (repetitions and word-finding difficulties), semantic (information units), and discourse (efficiency) domains. We discuss our findings in the light of current research and point to potential scientific and clinical uses of picture description tasks in the context of AD.

Authors: Lim Eun-Ye , Yang Dong-Won , Cho A-Hyun , Shim Yong S.
Published: July 2018

Background/Objective:

Vascular risk factors and neurovascular dysfunction may be closely related to cognitive impairment and dementia. In this study, we evaluated the association between hemodynamic markers and longitudinal cognitive changes in patients with mild cognitive impairment (MCI). Furthermore, we investigated whether hemodynamic markers could predict the risk of progression to Alzheimer’s disease (AD) in patients with MCI.

Methods:

A total of 68 subjects with amnestic MCI were recruited. Using transcranial Doppler (TCD) ultrasonography, cerebrovascular reactivity was evaluated with a breath-holding test (breath holding index; BHI) in addition to the mean flow velocity (MFV) and pulsatility index (PI) of the middle cerebral artery. We followed subjects for 24 months and each subject underwent neuropsychological testing and TCD ultrasonography, annually. According to the follow-up neuropsychological studies and clinical interviews at 12 months, we divided the patients with MCI into two groups: patients with stable cognitive performance and patients who progressed to AD.

Results:

Lower BHI and higher PI were observed in patients who progressed to AD. The changes of MMSE score over the first 12 months correlated with lower baseline MMSE score and changes of MFV and BHI. The changes of MMSE score over 24 months were closely related to higher baseline resistance index and PI values. Multivariate logistic regression showed that abnormal baseline BHI value could predict a conversion from MCI to AD.

Conclusions:

We confirmed there is a close association between hemodynamic changes represented by TCD markers and cognitive decline, supporting the clinical value of hemodynamic markers in predicting MCI patients who will progress to AD.
Can a Novel High-Density EEG Approach Disentangle the Differences of Visual Event Related Potential (N170), Elicited by Negative Facial Stimuli, in People with Subjective Cognitive Impairment?
Authors: Lazarou Ioulietta , Adam Katerina , Georgiadis Kostas , Tsolaki Anthoula , Nikolopoulos Spiros , (Yiannis) Kompatsiaris Ioannis , Tsolaki Magda
Published: July 2018

Background:

Studies on subjective cognitive impairment (SCI) and neural activation report controversial results.

Objective:

To evaluate the ability to disentangle the differences of visual N170 ERP, generated by facial stimuli (Anger & Fear) as well as the cognitive deterioration of SCI, mild cognitive impairment (MCI), and Alzheimer’s disease (AD) compared to healthy controls (HC).

Method:

57 people took part in this study. Images corresponding to facial stimuli of “Anger” and “Fear” were presented to 12 HC, 14 SCI, 17 MCI and 14 AD participants. EEG data were recorded by using a HD-EEG HydroCel with 256 channels.

Results:

Results showed that the amplitude of N170 can contribute in distinguishing the SCI group, since statistically significant differences were observed with the HC ( p < 0.05) and the MCI group from HC ( p < 0.001), as well as AD from HC ( p = 0.05) during the processing of facial stimuli. Noticeable differences were also observed in the topographic distribution of the N170 amplitude, while localization analysis by using sLORETA images confirmed the activation of superior, middle-temporal, and frontal lobe brain regions. Finally, in the case of “Fear”, SCI and HC demonstrated increased activation in the orbital and inferior frontal gyrus, respectively, MCI in the inferior temporal gyrus, and AD in the lingual gyrus.

Conclusion:

These preliminary findings suggest that the amplitude of N170 elicited after negative facial stimuli could be modulated by the decline related to pathological cognitive aging and can contribute in distinguishing HC from SCI, MCI, and AD.
What a fairer 24 team UEFA Euro could look like
Authors: Guyon Julien
Published: July 2018

In 2016, for the first time, the UEFA European Championship gathered 24 men’s national teams. It consisted of a group stage made of 6 groups of 4, followed by a knockout stage starting with the round of 16. We critically examine a number of flaws in the design of the knockout bracket that was used by UEFA: group advantage, lack of win incentive, and arbitrary choices. We suggest two fairer procedures that satisfy the balance and group diversity constraints but eliminate group advantage and significantly increase win incentive, hence interest, in the group stage. The suggested procedures use a global ranking of the 16 teams qualified to the knockout stage based on their performance during the group stage. They apply to any tournament consisting of a round robin stage made of 6 groups of 4, followed by a knockout stage. UEFA has decided to keep the 2016 format for Euro 2020, but has used our work to modify the knockout bracket so as to minimize group advantage.

Published: July 2018

OBJECTIVE:

Various imaging modalities have been used to diagnose suspicious breast lesions. Purpose of this study is to compare the diagnostic accuracy for breast cancer using mammography, ultrasonography and magnetic resonance imaging (MRI).

METHODS:

Total 107 patients aged from 19 to 62 years are included in this retrospective study. Mammography, ultrasonography and MRI scans were performed for each patient detected with suspected breast tumor within a month. In addition, the tumor diversity (10 types of benign and 5 types of malignant) was confirmed by pathological findings of tumor biopsy. To compare the diagnosis performance of the three imaging modalities, the overall fraction correct (accuracy), positive predict value (PPV), negative predict value (NPV), sensitivity and specificity were calculated. Meanwhile, the receiver operating characteristic (ROC) analysis was also performed.

RESULTS:

The diagnostic accuracy ranged from 78.5% to 86.9% among three imaging modalities. All modalities yielded a PPV lower than 77.8% and a NPV higher than 90.0% in identifying the presence of malignant tumors. MRI presented a diagnostic accuracy of 86.9%, as well as a sensitivity of 95.5% and an area under curve (AUC) of 0.948, which are higher than mammography and ultrasonography.

CONCLUSION:

By using a diverse dataset and comparing the diagnostic accuracy of three imaging modalities commonly used in breast cancer detection and diagnosis, this study also demonstrated that mammography, ultrasonography and MRI had different diagnostic performance in breast tumor identification. Among them, MRI yielded the highest performance even though the unexpected specificity may lead to over-diagnosis, and ultrosonography is slightly better than mammography.

Published: July 2018

Acute meningoencephalitis syndrome (AMES) is a life threatening condition of all ages caused by different microbial agents. Etiological diagnosis is imperative for introduction of appropriate antimicrobial agents to treat the condition. This cross sectional prospective study included seventy five (75) clinically suspected patients of AMES of different age and sex groups, who were admitted at Rajshahi Medical College Hospital (RMCH) during August, 2005 to Jun e, 2006. Cerebra spinal fluid (CSF) was studied by Gram-stained smear examination, bacterial culture, latex agglutination test (LAT), cytological and biochemical tests. The serum samples were also tested for qualitative C - reactive protein (CRP} by latex agglutination test and lgM anti body against Japanese Encephalitis (JE} virus by Enzyme-linked immunosorbent assay (ELISA). Direct microscopy on Gram-stained smears of CSF was found positive for 10 (13.33%) cases while bacterial culture was positive in 17(22.66%) cases. Culture yielded H. influenzae, S. pneumoniae  N.  meningitidis  and  Esch.  coli  in 07 (41.17%), 05 (29.41%), 04 (23.53%) and 01(5.88%) cases respectively. Higher rate of isolation was noted among 0-5 years age group. Out of 75 CSF samples, LAT could be done for randomly selected 45 cases with positive results observed in 18 (40%) cases. Good correlation of increase total white cell count and protein level and decrease glucose level was observed among culture-positive cases in cytological and biochemical analysis of CSF. Serum CRP was found positive in 21 (28.00%) cases and it had also excellent (94.11%) correlation with culture-positive cases. Among 75 patients, whose CSF samples were found apparently clear on physical examination, 40 of them were tested for serum lgM antibodies against JE virus with 4 (10%) cases as JE-positive in ELISA. All bacterial isolates were 100% sensitive to ceftriaxone and ciprofloxacin except S. pneumoniae which showed 80% sensitivity to ciprofloxacin in antimicrobial susceptibility testing. Variable sensitivity pattern was noted against penicillin, ampicillin, cotrimoxazole, gentamycin and erythromycin. This limited study has revealed that clinically suspected cases of AMES can have varying etiology with JE virus is an important cause detected among patients admitted in RMCH and Ceftriaxone is the drug of choice for bacterial meningitis.TAJ 2009; 22(1): 216-222

Spinal tuberculosis (Pott's disease) during pregnancy reported to be rare & can be associated with destruction of the intervertebral disc & adjacent vertebrae that can lead to cord compression & thereby paraplegia or quadriplegia. Delay in diagnosis is common & most cases are diagnosed when paraplegia has already been occurred. This serious complication requires special attention during pregnancy & delivery. Here we reported a case of term pregnancy with Pott's paraplegia. As the patient had complete motor & sensory loss from D7 level, (above the level of umbilicus to the lower limbs) LUCS was done without anesthesia & a healthy female baby was delivered. She did not require any analgesia post operatively.TAJ 2009; 22(1): 282-286

Authors: Nowshad MA , Mostaque A , Shahid SMA , Emrul HK
Published: July 2018

Laparoscopic appendectomy considered as superior alternative to open appendectomy. Usual laparoscopic appendectomy is performed with the three port system. In this study, we performed a unique single transumblical incision two-port laparoscopic assisted appendectomy with the aim to reduce postoperative port site complication as well as improving cosmesis and patients satisfaction. From January 2010, 32 patients were admitted with clinically diagnosed acute appendicitis and were randomly assigned to single transumblical incision two-port laparoscopic assisted appendectomy. Transumblical single incision two-port laparoscopic assisted appendectomy was attempted in all patients (9 males and 23 females) with an average age of 9.2 years. Transumblical single incision two-port laparoscopic assisted appendectomy was successfully completed in 31 patients. In one patient, another additional port required due to severe adhesion of the appendix. Mean operation time was 25.2 minutes (range, 17-38), and mean postoperative hospital stay was 1.Sdays (range 1-2). Postoperative complications (local pericaecal abscess) occurred in one case that was treated conservatively. Transumblical single incision two-port laparoscopic assisted appendectomy appears to be a feasible and safe technique for the treatment of acute appendicitis in the paediatric setting. It allows nearly scar less abdominal surgery. The true benefit of the technique should be assessed by randomized controlled trials.TAJ 2009; 22(1): 289-294
Neuropathic Pain and its Management
Authors: Ahmad Q , Ali M Ahmed , Kafiluddin M , Chowdhury MM Hoque
Published: July 2018

Pain arising as a direct consequence of a lesion or disease affecting the somatosensory system is defined as neuropathic pain. It is common in clinical practice affecting 6-8% of the general population causing considerable suffering and substantial reduction in the patients' health­related quality of life. Quality of the pain is often difficult to characterize but burning, tingling, lancinating, pricking terms are often used by patients to describe their pain. The response to stimulus is also altered causing allodynia, hyperalgesia and hyperpathia. Treatment is difficult with current therapies resulting in 30 to 50% reduction. Treatment aims to reduce suffering and disability with the reassurance that is rarely a life threatening condition.  The review describes the evidence-based pharmacologic treatment options available for the management of neuropathic pain.TAJ 2009; 22(1): 302-310
Quantum effects in a system of Boltzmann hard spheres
Authors: Stishov S M
Published: July 2018

The quantum contribution to the energy of a ‘Boltzmann’ gas consisting of hard spheres proves to be virtually constant up to very high temperatures where the thermal de Broglie wavelength constitutes only a small proportion of the hard sphere diameter. Consequently, the heat capacity of the system barely differs from the classical value of (3/2) k
B everywhere except in the lowest temperature region, where heat capacity as a function of temperature has the ‘Debye’ form but with a very low Debye temperature, of the order of several degrees. The line of equilibrium between a quantum crystal and liquid for a ‘Boltzmann’ system of hard spheres coincides with the classical one, with the exception of the very-low-temperature region. High-temperature quantum effects are revealed in the system under consideration in a kind of ‘bare’ form, while in the case of more realistic systems or models they can be masked by the complex behavior of other components of the total energy.

Published: July 2018

Zearalenone (ZEA) is a natural contaminant existing in food and feed products that exhibits a negative effect on domestic animals’ reproduction. Donkeys possess high economic value in China and are at risk of exposure to ZEA. However, few information is available on ZEA-induced toxicity and no report on toxicity in donkeys can be found in scientific literature. We investigated the biological effects of ZEA exposure on donkey granulosa cells (dGCs) by using RNA-seq analysis. ZEA at 10 and 30 μM were administered to GCs within 72 h of in vitro culture. ZEA at 10 μM significantly altered the tumorigenesis associated genes in dGCs. Exposure to 10 and 30 μM ZEA treatment significantly reduced mRNA expression of PTEN, TGFβ, ATM, and CDK2 genes, particularly, the ZEA treatment significantly increased the expression of PI3K and AKT genes. Furthermore, immunofluorescence, RT-qPCR, and Western blot analysis verified the gene expression of ZEA-exposed GCs. Collectively, these results demonstrated the deleterious effect of ZEA exposure on the induction of ovarian cancer related genes via the PTEN/PI3K/AKT signaling pathway in dGCs in vitro.
Coordinated Assembly of Brightest Cluster Galaxies
Authors: Gu Meng , Conroy Charlie , Brammer Gabriel
Published: July 2018

Brightest Cluster Galaxies (BCGs) in massive dark matter halos are shaped by complex merging processes. We present a detailed stellar population analysis in the central region of Abell 3827 at z ∼ 0.1, including five-nucleus galaxies involved in a BCG assembly. Based on deep spectroscopy from the Multi Unit Spectroscopic Explorer, we fit the optical spectra of 13 early-type galaxies (ETGs) in the central 70 kpc of the cluster. The stellar populations in the central R = 1 kpc of these ETGs are old (>6 Gyr). Their [Fe/H] increases with σ
⋆ and stellar mass. More importantly, [α/Fe] of galaxies close to the cluster center do not seem to depend on σ
⋆ or stellar mass, indicating that the cluster center shapes the [α/Fe]–σ
⋆ and [α/Fe]–M
⋆ relations differently than other environments where [α/Fe] is observed to increase with increasing σ
⋆ or M
⋆. Our results reveal the coordinated assembly of BCGs: their building blocks are different from the general low-mass populations by their high [α/Fe] and old ages. Massive galaxies thus grow by accreting preferentially high [α/Fe] and old stellar systems. The radial profiles also bear the imprint of the coordinated assembly. Their declining [Fe/H] and flat [α/Fe] radial profiles confirm that the accreted systems have low metallicity and high [α/Fe] stellar contents.
Solar Kinetic Energy and Cross Helicity Spectra
Authors: Zhang Hongqi , Brandenburg Axel
Published: July 2018

We develop a formalism that treats the calculation of solar kinetic energy and cross helicity spectra in an equal manner to that of magnetic energy and helicity spectra. The magnetic helicity spectrum is shown to be equal to the vertical part of the current helicity spectrum divided by the square of the wavenumber. For the cross helicity, we apply the recently developed two-scale approach globally over an entire active region to account for the sign change between the two polarities. Using vector magnetograms and Dopplergrams of NOAA 11158 and 12266, we show that kinetic and magnetic energy spectra have similar slopes at intermediate wavenumbers, where the contribution from the granulation velocity has been removed. At wavenumbers around

, the magnetic helicity is found to be close to its maximal value. The cross helicity spectra are found to be within about 10% of the maximum possible value. Using the two-scale method for NOAA 12266, the global cross helicity spectrum is found to be particularly steep, similarly to what has previously been found in theoretical models of spot generation. In the quiet Sun, by comparison, the cross helicity spectrum is found to be small.

We present Infrared Telescope Facility/SpeX and NEOWISE observations of the dynamically new comet C/2013 US10 (Catalina), hereafter US10, from 5.8 au inbound, to near perihelion at 1.3 au, and back to 5.0 au outbound. We detect water ice in the coma of US10, assess and monitor the physical properties of the ice as insolation varies with heliocentric distance, and investigate the relationship between water ice and CO2. This set of measurements is unique in orbital coverage and can be used to infer both the physical evolution of the ice, and, potentially, the nucleus composition. We report (1) nearly identical near-infrared spectroscopic measurements of the coma at −5.8 au, −5.0 au, +3.9 au (where <0 au indicates pre-perihelion epochs), all presenting evidence of water-ice grains, (2) a dust-dominated coma at 1.3 and 2.3 au and, (3) an increasing CO2/Afρ ratio from −4.9 to 1.8 au. We propose that sublimation of the hyper-volatile CO2 is responsible for dragging water-ice grains into the coma throughout the orbit. Once in the coma, the observability of the water-ice grains is controlled by the ice grain sublimation lifetime, which seems to require some small dust contaminant (i.e., non-pure ice grains). At

, the ice grains are long-lived and may be unchanged since leaving the comet nucleus. We find that the nucleus of comet US10 is made of, among other components, ∼1 μm water-ice grains containing up to 1% refractory materials.
Reverse Current Model for Coronal Mass Ejection Cavity Formation
Authors: Haw Magnus A. , Wongwaitayakornkul Pakorn , Li Hui , Bellan Paul M.
Published: July 2018

We report here a new model for explaining the three-part structure of coronal mass ejections (CMEs). The model proposes that the cavity in a CME forms because a rising electric current in the core prominence induces an oppositely directed electric current in the background plasma; this eddy current is required to satisfy the frozen-in magnetic flux condition in the background plasma. The magnetic force between the inner-core electric current and the oppositely directed induced eddy current propels the background plasma away from the core, creating a cavity and a density pileup at the cavity edge. The cavity radius saturates when an inward restoring force from magnetic and hydrodynamic pressure in the region outside the cavity edge balances the outward magnetic force. The model is supported by (i) laboratory experiments showing the development of a cavity as a result of the repulsion of an induced reverse current by a rising inner-core flux-rope current, (ii) 3D numerical magnetohydrodynamic (MHD) simulations that reproduce the laboratory experiments in quantitative detail, and (iii) an analytic model that describes cavity formation as a result of the plasma containing the induced reverse current being repelled from the inner core. This analytic model has broad applicability because the predicted cavity widths are relatively independent of both the current injection mechanism and the injection timescale.

Amanitatullossiana, a new species ofAmanita[subgenus Lepidella] section Lepidella from India is described. The species is characterised by its ash grey to brownish-grey pileus covered with dark grey to greyish-black universal veil remnants, the upper part of its rooting stipe base covered by several rows of recurved scales, broadly ellipsoid to ellipsoid basidiospores, absence of basidial clamp connections and pileal remnants of universal veil comprising abundant, disordered inflated cells intermixed with scattered filamentous hyphae. Molecular phylogenetic analysis and morphology both support the association ofA.tullossianawith species of Bas’ stirpsCinereoconia–A.cinereoconiaandA.griseoverrucosa. Two species,A.griseoverrucosaandA.virgineoidesare reported here as new records for India.
La prise de conscience de la nécessité d’une gouvernance plus responsable progresse
Authors: Notat Nicole , Crifo Patricia , Mahieux Xavier
Published: July 2018

En matière de gouvernance, la situation française se caractérise par la coexistence de plusieurs modèles en raison de la multiplicité des formes juridiques (sociétés anonymes, mutualistes, etc.) et de la composition des conseils d’administration, parfois encore teintés de consanguinité, avec une dissociation ou non des pouvoirs qui fait encore débat et une très faible représentativité des salariés en leurs seins. Sur ce point, la France est réellement à la traîne et les réticences sont encore importantes, même si la loi Rebsamen impose cette représentation depuis 2015. Plus généralement, les freins à l’évolution vers une gouvernance socialement responsable sont liés à la représentation que les chefs d’entreprises se font de leur rôle et à la recherche de rentabilité, souvent à court terme, des investisseurs. Mais les choses évoluent, notamment du côté des investisseurs qui comprennent que leur intérêt d’actionnaires bien compris est de prendre en compte les intérêts des parties prenantes, en particulier sur les enjeux sociaux et environnementaux, et d’agir en ce sens auprès des entreprises. L’évolution de l’activité des agences de notation extra-financières telles que Vigeo confirme cette tendance. Classification JEL : G32, G34, K22, M12, M14.
L’évolution de l’actionnariat en France : 1977-2017
Authors: Auvray Tristan
Published: July 2018

Cet article retrace les grandes tendances de l’actionnariat français des sociétés cotées et non cotées à partir de la fin des années 1970, et plus spécialement en ce début de xxi e  siècle, vingt ans après l’éclatement du cœur financier français. Nous proposons une méthode originale, combinant les comptes de patrimoines et les statistiques sur les IDE de la Banque de France, ainsi que l’enquête CPIS du FMI, pour donner des ordres de grandeurs sur la localisation de cet actionnariat et le type de ses prises de participations. Pour caractériser de manière plus détaillée l’évolution de l’actionnariat des sociétés cotées françaises sur la période récente, nous nous focalisons ensuite sur les grandes sociétés de la place de Paris. Malgré la grande rupture qu’a été la montée des investisseurs institutionnels états-uniens à la fin des années 1990, l’actionnariat des grandes sociétés cotées a connu une forte stabilité dans ses niveaux de concentration depuis 2002, ce qui ne doit pas dissimuler la montée, aux côtés des actionnaires de contrôle traditionnels, de nouveaux actionnaires de contrôle (fonds souverains, hedge funds et groupes étrangers). De même, si la concentration des cinq premiers actionnaires est stable, les participations du premier actionnaire tendent à diminuer, conférant plus de poids relatif aux autres détenteurs de blocs d’actions.

Familles actionnaires
Authors: Ginglinger Edith
Published: July 2018

Les firmes familiales représentent une large part des entreprises cotées dans le monde. Les mécanismes de gouvernance des firmes familiales tiennent compte des spécificités de leurs conflits d’agence. Par exemple, les conflits d’agence entre actionnaires et dirigeants peuvent être atténués lorsque les dirigeants sont eux-mêmes membres de la famille. Les coûts des conflits d’agence entre le bloc familial majoritaire et les actionnaires minoritaires, liés aux prélèvements potentiels de bénéfices privés, peuvent être compensés par un contrôle plus efficace des dirigeants, tandis qu’un conflit d’agence spécifique lié aux relations entre la famille dans son ensemble et ceux qui la représentent dans l’organisation du bloc actionnarial peut émerger. Les mécanismes de gouvernance mis en place semblent efficaces, puisque les firmes familiales apparaissent plus performantes que les firmes non familiales. Mais elles sont également moins diversifiées, moins innovantes et plus sensibles au climat social dans l’entreprise. Leurs décisions financières reflètent le souci de leurs actionnaires familiaux de préserver leur contrôle qui passe en particulier par l’établissement de relations de long terme avec les autres parties prenantes de l’entreprise. Cet article propose une synthèse des résultats de recherches sur ces sujets. Classification JEL : G30, G32, L21, L25, P12.
Conflits d’intérêts et gouvernance des banques systémiques : éléments d’analyse critique
Authors: Scialom Laurence
Published: July 2018

Nous définissons dans cet article deux grandes catégories de conflits d’intérêts concernant les banques systémiques : des conflits d’intérêts d’ordre microéconomique qui portent atteinte à la responsabilité fiduciaire des banques vis-à-vis de leurs clients et les conflits d’intérêts d’ordre macroéconomique qui nuisent à l’intérêt de la société dans son ensemble et alimentent la défiance sociale vis-à-vis des banques. L’hypothèse de cet article est que les scandales financiers à répétition qui éclaboussent les grandes banques systémiques internationales ne sont pas un épiphénomène, mais au contraire le symptôme des failles de leur gouvernance et des conflits d’intérêts non traités qui les minent. Le décryptage des conditions permissives au relâchement des normes éthiques dans la banque est important pour la stabilité financière, pour la confiance dans le système financier et devrait avoir des implications majeures en termes d’action publique. Nous plaidons donc pour que les économistes investissent ce terrain de recherche. Classification JEL : G21, G28, G34, G38.
La dimension « relation client » du métier de conducteur-livreur, un facteur d’engagement envers le métier
Authors: Jacquemier-Paquin Laure , Claye-Puaux Sophie , Jeanpert Sophie
Published: July 2018

Le secteur du transport routier de marchandise connaît de profondes mutations. Le métier de conducteur-livreur s’est enrichi et exige de nouvelles compétences dans le domaine de la relation client, lors des livraisons des clients distributeurs notamment. Une enquête exploratoire, par questionnaire, auprès de 203 conducteurs, a permis d’examiner le rôle finalement crucial de cette dimension relationnelle avec le client, qui est contributrice d’un plus fort engagement affectif et normatif envers ce métier en tension. La recherche contribue à l’analyse de l’influence des perceptions du métier sur le comportement des employés en matière d’engagement professionnel. Elle permet de mettre en lumière des leviers propres au contenu du métier pour en améliorer l’attractivité.
Les défis socio-économiques liés à la chirurgie robot-assistée dans les blocs opératoires : espaces d’échanges et artefacts médiateurs
Authors: Wannenmacher Delphine
Published: July 2018

L’arrivée de la robotique en chirurgie modifie l’activité des équipes de bloc opératoire. Elle engendre une reconfiguration spatiale du bloc et a un impact sur le fonctionnement de l’équipe de travail notamment au niveau de la communication et de l’organisation du travail. Les recherches dans le domaine mettent en avant l’intérêt de la check-list et le développement de compétences non techniques en insistant sur la formation et l’évaluation de ces dernières notamment dans un objectif de performance. Dans un cadre plus global d’apprentissage expansif et par le biais d’une démarche pragmatiste, nous proposons une autre piste : la création d’espaces d’échanges médiés par des artefacts pour transformer les pratiques au sein du bloc opératoire.
Internal barriers to supply chain management implementation in a South African traditional university
Authors: Masete Mamokgadi Z. , Mafini Chengedzai
Published: July 2018

Background: The demand for higher education in South Africa continues to increase, placing pressure on public higher education institutions to satisfy this demand. Supply chain management is one of the practices that may be implemented to ensure that public universities improve their operations and can, therefore, meet the increased demand for higher education in the country.Objectives: This study aimed to explore the barriers to the implementation of supply chain management practices at a South African public university.Method: The study used a qualitative case study approach using a sample of 17 members of management and staff at a South African traditional university in the Limpopo Province. Data were collected using a combination of a focus group discussion and semi-structured in-depth interviews.Results: The study generated eight themes that embody the barriers to the implementation of supply chain management at the institution. These themes were labelled as stakeholder buy-in, knowledge of supply chain management, supply chain systems and processes, procurement policy and practices, implementation of supply chain management, stakeholder change management, human resource management and organisational culture.Conclusion: Various internal barriers impair the implementation of supply chain management practices at the institution. Administration at the institution has invested limited resources, time and initiatives to ensure the successful implementation of supply chain management. The focus should be directed to finding lasting solutions to each of the barriers identified in this study. Further studies should address the issue of external barriers to supply chain management in public higher education institutions.
Evaluating South Africa’s utilisation of sustained export potential in sub-Saharan Africa
Authors: Mhonyera Gabriel , Steenkamp Ermie , Matthee Marianne
Published: July 2018

Background: Regional trade could be a powerful engine of economic growth and sustainable job creation. However, South Africa’s exports to sub-Saharan Africa (SSA) are typically smaller and more short-lived than its exports to its traditional markets. This is despite South African policymakers considering trade with SSA to be a priority. Aim: The aim of the article is to evaluate South Africa’s utilisation of sustained export potential in SSA with a view to providing practical insights that will inform future policymaking and planning. Setting: Despite the priority attention given to SSA in the country’s trade policy, South Africa is yet to make meaningful inroads into SSA’s largest and fastest-growing economies. Method: The research method applied comprised three steps. The first step involved the identification, over a five-year period from 2010 to 2014, of consistently large and/or growing import demand in SSA for all products at the Harmonised System (HS) six-digit level, as well as the identification of products South Africa consistently exported competitively (sustainable exports). The second step entailed matching SSA markets with consistently large and/or growing import demand to South Africa’s sustainable exports. The third step involved evaluating South Africa’s utilisation of sustained export potential in SSA. Results: The results reveal that South Africa is utilising just over half (54%) of its sustained export potential in SSA. Conclusion: South Africa is, therefore, underutilising or not utilising close to 50% of its sustained export potential in SSA. Most of the export potential that South Africa is utilising is in Eastern Africa while most of the export potential that the country is underutilising and not utilising at all is in Central and Western Africa.
A comparison of retirement saving using discretionary investment and Regulation 28
Authors: Willows Gizelle D. , Burgers Thomas , West Darron
Published: July 2018

Background: There is growing uncertainty in global society with regard to how retirement savings should be approached. The primary reason for this is that most societies do not save enough and their citizens run out of money during retirement. Aim: This study investigates whether the limitations imposed by Regulation 28 of the Pension Funds Act of South Africa encourage optimal asset allocation and reduce investment risk for retirement savings when contrasted with discretionary investment. Setting: The study looks at hypothetical individuals who are subject to tax and retirement consequences as administered by South African legislation. Methods: A quantitative risk and return analysis was performed while considering two hypothetical investors who are identical in all aspects other than their choice of investments. Results: The findings indicate that Regulation 28 is effective in reducing the investment risk of retirement savings; however, it may also force the investor to sacrifice wealth. Conclusion: Depending on the tax bracket in which the investor sits, discretionary investment may be preferential to investing in a retirement fund under the mandate of Regulation 28.
