PREDIKTORI NAVIJAČKOG IDENTITETA: DEMOGRAFSKI POKAZATELJI, DIMENZIJE REVIDIRANOG GRAYOVOG MODELA I KOGNICIJE O NASILJU
Authors: Otašević Biljana , Sekereš Valentina
Published: January 2016

Većina teorijskih pristupa fenomenu sportskog navijanja usmerena je na objašnjenje nasilnog ponašanja organizovanih navijačkih grupa i uglavnom je zasnovana na disciplinarno ograničenim modelima. Osnovni cilj ovog rada bio je ispitivanje eksplanatorne moći modela predikcije navijačke identifikacije sportskih fanova, kojim su obuhvaćena tri seta varijabli: sociodemografski prediktori (pol, starost, obrazovanje, materijalni status), dispozicione karakteristike (dimenzije modela Grayove revidirane Teorije osetljivosti na potkrepljenje – Osetljivost na signale nagrade, Osetljivost na signale kazne, Borba, Bežanje i Blokiranje) i nasilne kognicije (mačizam i prihvatanje nasilja). Na uzorku od 147 ispitanika (54.4% ženskog pola), starosti između 16 i 61 godina, primenjeni su sledeći instrumenti: Upitnik navijačkog identiteta, Upitnik za procenu osetljivosti na potkrepljenje, Upitnik stavova prema nasilju i kratak upitnik o sociodemografskim karakteristikama. Rezultati hijerarhijske regresione analize sugerišu da svaki od prediktorskih setova (demografski, dispozicioni i kognitivni) ostvaruje značajan doprinos predikciji kriterijuma, ukazujući na važnost uključivanja svake od tri kategorije varijabli u model predikcije navijačke identifikacije. Pored toga, rezultati govore o značajnoj ulozi muškog pola i mačizma, kao samostalnih prediktora u konačnom modelu, dok je statistička značajnost doprinosa Bežanja, kao dimenzije ličnosti, nestala nakon uključivanja nasilnih kognicija u regresionu jednačinu. Posmatrani u celini, dobijeni rezultati ukazuju na neopravdanost pripisivanja agresivnosti, impulsivnosti i podržavanja nasilja visoko identifikovanim sportskim fanovima, budući da sama identifikacija sa timom nije povezana sa antisocijalnim i nasilnim obeležjima. Kao činioci koji doprinose navijačkom identitetu, u skladu sa ranijim istraživanjima, pokazale su se pripadnost muškom polu i maskulina orijentacija ka polnoj ulozi, izražena mačističkim stavovima i manifestnom neustrašivošću.

Published: January 2016

Working life research does not have clear boundaries; however its focus is quite clear: Changes in working life and how these changes affect qualifications, health, occupations, innovation, the economy, identity, social orientation and culture. The density of working life research is quite high in the Nordic countries, and this research has always been involved in the development of the Nordic welfare societies in which the development of work has been one important factor. In this article working life research is presented in its historical contexts, emphasizing the welfare challenges to which the research has been related. The challenges and tensions related to the research are not presented as being simply internal to the research work, they also reflect challenges and tensions in working life and institutions that are supposed to support working life. Current controversies in working life research in the four Nordic countries will briefly be presented, and institutional challenges for the research in the four countries will be exemplified. Finally, the aims of the journal will be outlined.
Workplace Development as Part of Broad-based Innovation Policy: Exploiting and Exploring Three Types of Knowledge
Authors: Alasoini Tuomo
Published: January 2016

This paper looks at the possibilities that a broad-based innovation policy contained by the national innovation strategy recently adopted in Finland opens up for the promotion of workplace innovations and examines the types of knowledge needed in workplace development. The author highlights the interconnections between workplace development and the prerequisites of both economic growth and the preservation of the Finnish welfare state. The paper also aims to explain why, in addition to the productivity of work, improving the quality of working life should feature as an increasingly important aim in the innovation policy of the future. An argument for the need of three types of knowledge in workplace development - design knowledge, process knowledge and dissemination knowledge - is made, together with an overview on new developments in each of those three domains. In conclusion, the author demonstrates how problems in the productivity of work and the quality of working life can be simultaneously tackled with at work organization level through two kinds of development approaches.
Increasingly Equalized? A Study of Part-Time Work in ‘Old’ and ‘New’ Part-Time Work Regimes
Authors: Nicolaisen Heidi
Published: January 2016

Recent debates on equalization of part-time work alongside full-time work stress the importance of high quality part-time jobs. This paper compares equalization in banking in three countries: two `old´ part-time work regimes, Norway and Sweden, and Ireland, where part-time work started to increase more recently. Banking is particularly interesting as a sector with a high proportion of female employment and good working conditions. One main interest is the role of regulations and how they are enforced at company level. The analysis shows that part-time work in the Nordic countries is normalized in terms of access and general work conditions, while in Ireland access is more restricted. Career opportunities are, however, restricted in all three countries. This paper argues that further equalization may be hindered by `soft´ regulations and a gradual normalization process that also normalizes disadvantages associated with part-time work and the category of the `working mother´.
Temporary Agency Workers—Precarious Workers? Perceived Job Security and Employability for Temporary Agency Workers and Client Organization Employees at a Swedish Manufacturing Plant
Authors: Håkansson Kristina , Isidorsson Tommy
Published: January 2016

The vulnerable situation of temporary agency workers is manifested in previous research that evidences the job insecurity of this group. However, research shows that this insecurity is due to the temporary nature of employment contracts for this group of workers. In Sweden, where temporary agency workers have the same type of employment contracts (i.e., temporary or permanent contracts) and are entitled to the same employment protection as other groups of employees, one might expect a different picture. This article examines the situation of temporary agency workers who have the same working conditions as client organization employees. These workers have permanent contracts and are treated like client organization employees. We have chosen to examine this case because we anticipate it to be very likely to contradict statements regarding temporary agency workers’ affiliation with the precariat. This article aims to empirically elucidate the precariousness of temporary agency workers who are highly integrated with client organization employees and who share the same work tasks. Our analysis shows that competence development is crucial to perceptions of job security. However, temporary agency workers lack competence development, both on the part of the employer (the temporary work agency) and on the part of the client organization. The client organization has no incentive to invest more than the required competencies, since temporary agency workers only constitute a buffer in case of a downturn. We argue that it is the agency workers’ connection with a buffer that results in a lack of job security. Our results also show that temporary agency workers’ job security could be increased if temporary agencies were to invest in competence development for the agency workers, thus overcoming these workers’ vulnerability in constituting a buffer.
Working in the Same Sector, in the Same Organization and in the Same Occupation: Similarities and Differences Between Women and Men Physicians’ Work Climate and Health Complaints
Authors: Falkenberg Helena , Näswall Katharina , Lindfors Petra , Sverke Magnus
Published: January 2016

Due to the segregated labor market, gender differences in health are often confounded by factors such as sector or occupation. This study explored similarities and differences in work climate and health complaints among women and men working in the same sector, in the same organization, and in the same occupation. First, work climate and health complaints were compared between women and men. Second, relations between the work climate and health complaints were investigated in both genders. Questionnaire data were collected from 95 women and 105 men physicians who worked in the same acute care hospital in Sweden. The results showed no gender differences in the job, role, leadership, or organizational characteristics. However, women physicians reported less workgroup cohesiveness and cooperation and more mental and physical health complaints than men physicians. Workgroup cohesiveness and cooperation were related to less health complaints only for men physicians. This explorative study indicates similarities between women and men when the work situation is similar, but suggests that some of the differences that appear in the large structures of the gender-segregated labor market also seem to be present for women and men who work in the same sector, in the same organization, and in the same occupation.
Assessment of membrane fouling indices during removal of reactive dye from batik wastewater
Authors: Amin Indok Nurul Hasyimah Mohd , Nizam Muhamad Hafiz Muhammad
Published: January 2016

‘Batik’ is known as one of the most popular textile industries in Malaysia, and it produces wastewater in its processing. The wastewater contains reactive dye and is released into drains as well as rivers. It could cause harm to the environment and interrupt the food chain due to the chemicals contained in it. The aim of the present study is to determine the flux performance and modified fouling index using ultrafiltration (MFI-UF) by using different membrane materials, feed concentrations and feed chemistry. The sample was obtained from Romi Batik located at Chendering Terengganu. Two UF membranes were used, with the membrane materials made from cellulose acetate and polyvinylidene fluoride (PVDF). The permeate flux and fouling indices were investigated at the solution pH values of 3 and 7 for different concentrations. It was clearly observed that the highest percentage dye rejection and MFI-UF obtained at pH 7 using a PVDF membrane was a value of 85.3792% and 72,088 s/L2, respectively. Overall results revealed that an ultrafiltration process can be used to treat reactive dye from textiles before it is channelled into the sea or rivers, and has great potential to be commercialized as a new alternative in dye wastewater treatment.
Book review: Mining and Quarrying in the Ancient Andes: Sociopolitical, Economic and Symbolic Dimensions
Authors: Ixer Robert A. F. F.-X.
Published: January 2016

The high Andes is one of the world’s great metallogenic provinces having produced and still providing very significant amounts of copper, silver, tin and historically, of course, gold.  The Andean pre-Colombian metal mining tradition, clearly isolated from that of Eurasia, provides independent alternative examples of early, non-mechanised mining and its less tangible ‘sociopolitical, economic and symbolic dimensions’.
Eternal dilemma of the interplay between coexisting tuberculosis and malignancy: Clinical scenario of coexisting submandibular carcinoma with disseminated tuberculosis: A case report
Authors: Shah Manjari , Leekha Nitin , Gupta Sweety , Sowmiya S , Garg Garima , De Sudarsan
Published: January 2016

Tuberculosis (TB) and malignancy are two lethal diseases that cause significant morbidity and mortality in developing countries like India. Extrapulmonary tuberculosis (TB) constitutes about 15 to 20 per cent of all cases of tuberculosis with lymph nodes being the most common site of involvement.1 Malignant transformation in pleomorphic adenoma lead to carcinoma ex pleomorphic adenoma (CXPA). CXPA of the salivary glands, however, is relatively uncommon, accounting for 3.6 % of all salivary gland neoplasms and 11.7 % of all malignant salivary gland neoplasms.2 Here we report a case of carcinoma ex pleomorphic adenoma of submandibular gland which presented as a swelling in submandibular region along with generalized lymphadenopathy which mimicked widespread metastases but later on histologically showed tuberculosis. Asian Journal of Medical Sciences Vol. 7(3) 2016 115-117

Background: UTI is most distribution of uropathogens amongst the community & hospitalized patients suffering bacterial infection. Aims and Objectives: It affects person throughout their life span. It may be characterized as uncomplicated (occurring without an anatomic or other predisposing reason) or complicated (associated with structural or functional abnormalities of the urinary tract & kidney). A single bacterial species Escherichia coli, causes majority of UTI. Materials and Methods: Total of 426 clinically diagnosed uti cases were subjected to culture & its correlation with various screening tests such as wet film microscopy, TTC & Gram stain & its sensitivity, specificity, positive & negative productive value were determine along with anti microbial susceptibility also virulence factor of E. coli & ESBL production were studied. Results:  Present study showing UTI was more common in females 281 (65.96%) as compared to 145 (34.03%) in males. As compare with culture, sensitivity of TTC, wet film microscope were 78.22%, 81.91% & 97.41% respectively. Amongst total 271 culture isolates E. coli were more common, highest resistant was observed to ampicillin (90.78%) followed by amoxyclave (86.64%), cotrimoxazole (82.23%) & carbenicillin (78.94%), whereas highest sensitivity noted against imipenem (100%). Conclusion:  It is evident UTI is more common in reproductive females & in case of males in older age.    Asian Journal of Medical Sciences Vol. 7(3) 2016 108-114
Prevalence of head and neck tumours in Calabar, South Eastern Nigeria
Authors: Kanu Okezie Obasi , Nnoli Martin A. , Asoegwu Chinyere A.
Published: January 2016

Background: Malignancies in the head and neck region though relatively rare, compared to other regions of the body, they contribute significantly to morbidity and mortality in affected patients. In Nigeria, the burden of managing head and Neck malignancies is enormous and there is yet to be a unified record of nation-wide incidence of malignancies involving the head and neck region despite the fact the head and neck malignancies have been diagnosed and documented since the 1960’s. The histological pattern and frequency however seems to have some slight variation depending on the region and the identified aetiological risk factors.Aims and Objectives: The aim of this study was to determine the pattern of head and neck tumours seen in the region and the commonest malignancies in the cohort. By comparing the relative prevalence of the lesions with other centers in the country and international published literature we hope to make a case for proper tumour registry and move for nation-wide studies.Materials and Methods: The authors reviewed the histopathological data of the tumor registry at the University of Calabar Teaching Hospital, a major referral Center in South-Eastern Nigeria between 2005 and 2012. All cases of head and Neck tumours with histological diagnosis were included for analysis, their demographic data were obtained and analyzed using SPSSv16.Results: Two hundred and twenty-five specimens from the head and neck region were analyzed during this 6 year period giving an average of 34 cases per year. The Male: Female ratio was 1.2:1.The age range was from 2 years to 76 years with overall mean of 32.7 years. One hundred and forty-five cases (63.3%) were benign while 84 malignant cases (36.7%) were recorded for the study period. The average number of new malignant cases seen was 14 per year. Malignancies were commoner in those less than 50 years of age and were mostly those of epithelial origin.Conclusion: Variations in the regional demographics of head and neck tumors in the country could be accounted for by the differences in data collection methods and certain aetiological factors that may be unique to those regions. A proper tumor registry in each region, harmonized with a national cancer registry may resolve some of these discrepancies.Asian Journal of Medical Sciences Vol. 7(3) 2016 123-126
Heuristics to Improve Efficiency of Solution Algorithm of Path Flow Estimator
Authors: Li Tao
Published: January 2016

The path flow estimator (PFE) proposed by Bell and Shield in 1997 is an important demand estimator in ground transportation. The PFE is formulated as a nonlinear optimization model and solved by the iterative balancing solution algorithm given by Bell in 1995. This paper presents several theoretical results about the solution algorithm. In particular, the solution algorithm is shown to maximize the dual problem of the PFE sequentially along the directions defined by unit vectors. A closed-form relationship was identified between the increase in the objective of the dual problem and the optimal step length along each direction. In addition, three heuristics were developed to improve the computational efficiency of the solution algorithm. The first heuristic reduced the computational effects that could not yield significant increases to the objective value of the dual. The second reduced the probability of yielding marginal increases to the objective value of the dual. The third sped up convergence by partially avoiding zigzagging (i.e., approaching the optimal solution in small steps along perpendicular directions). The heuristics could be applied simultaneously with each other or with the methods developed to determine better initial values. The three heuristics were applied to a large-sized network, and the computational results were generally consistent with the theoretical results.
Hierarchical Multiresolution Traffic Simulator for Metropolitan Areas
Authors: Li Pengfei , Mirchandani Pitu , Zhou Xuesong
Published: January 2016

This paper presents a hierarchical multiresolution traffic simulation system for metropolitan areas, referred to as METROSIM. Most multi-resolution traffic simulation systems are single level, and different simulators represent different portions within the same network. In contrast, METROSIM has two hierarchical levels: an open-source mesoscopic traffic simulator for regional dynamic traffic assignment (DTALite) and a popular commercial microscopic traffic simulator (PTV VISSIM) for intersection and corridor traffic operations. Unlike the traditional network modeling method, METROSIM starts from the microscopic simulation network and migrates into the mesoscopic network while reserving all the high-fidelity details, such as geometric design and signal head locations. The DTALite network and the VISSIM network represent two independent but highly consistent networks, and they exchange data while both simulation engines are running to overcome some long-standing issues in single-level systems, including the consistency of network representation and route choice, computing efficiency, and precise simulation of the subareas with the greatest interest. This paper offers insight into the development of multiresolution systems and focuses on topics such as network migration, parallel computing, and interprocess data integration. A case study demonstrates the potential applications of METROSIM.
Surrogate-Based Optimization for Solving a Mixed Integer Network Design Problem
Authors: Chen Xiqun (Michael) , Zhu Zheng , He Xiang , Zhang Lei
Published: January 2016

This paper considers the bilevel mixed network design problem (MNDP) used in dynamic traffic assignment (DTA) and the simulation-based optimization solution. The upper level of the bilevel MNDP minimizes the network cost in terms of average travel time by the expansion of existing links and the addition of new candidate links. The lower level is a dynamic user-optimal condition that can be formulated as a variational inequality problem. The MNDP simultaneously finds optimal capacity expansions of existing links and new link additions. A surrogate-based optimization (SBO) framework is proposed for solving the MNDP that is characterized by expensive-to-evaluate objective functions. Because simulation was applied to evaluate those objective functions, additional complexity arose from the fine-grained representation of traffic dynamics in large-scale networks, which were not fully considered by the traditional static user equilibrium. SBO methods enjoy both the advantages of simulation in time-varying network performance evaluation and the efficiency of mathematical optimization. To be more specific, SBO produces computational time savings by exploring the input–output mapping surface in a more systematic and efficient way. For demonstrative purposes, a case study was conducted on the large-scale Montgomery County network in Maryland. In this example, a mesoscopic simulation-based DTA model, DTALite, was used to evaluate the system performance in response to various network design strategies. Results showed that the optimal investment with a moderate budget could reduce 17.73% of the network average travel time in the morning peak. The proposed framework is a general approach, which is ready for application to either continuous or discrete network design problems.

Dilemmata and Dimensions of Childrens Reading Comprehension Skills
Authors: Hoque Mohammed Shamsul
Published: January 2016

Learners have to deal with texts they read in many different ways. Some learners comprehend better than others; some take a little while to get to the deeper meanings of the text while some get to the meaning instantly. Some may find it difficult to comprehend even at surface level. Psychologists, linguists and educators have been divided in their opinions about how a young learner comprehends a text and why they are better or worse than their peers in comprehending text. In this article attempts have been made to present a clear definition of what is comprehension; how comprehension happens among readers before, during and after reading; what makes a learner a good or a poor comprehender. While presenting this phenomenon in brief, mentions and citations have been made from established researches /studies in this area along with observations of acknowledged psycholinguists, educators and practitioners. Finally, with support from different studies, an attempt has been made to describe ways and means as to how to improve learners' reading comprehension.Philosophy and Progress, Vol#53-54; No#1-2; Jan-Dec 2013
A Global Index for Mapping the Exposure of Water Resources to Wildfire

Published: January 2016

Wildfires are keystone components of natural disturbance regimes that maintain ecosystem structure and functions, such as the hydrological cycle, in many parts of the world. Consequently, critical surface freshwater resources can be exposed to post-fire effects disrupting their quantity, quality and regularity. Although well studied at the local scale, the potential extent of these effects has not been examined at the global scale. We take the first step toward a global assessment of the wildfire water risk (WWR) by presenting a spatially explicit index of exposure. Several variables related to fire activity and water availability were identified and normalized for use as exposure indicators. Additive aggregation of those indicators was then carried out according to their individual weight. The resulting index shows the greatest exposure risk in the tropical wet and dry forests. Intermediate exposure is indicated in mountain ranges and dry shrublands, whereas the lowest index scores are mostly associated with high latitudes. We believe that such an approach can provide important insights for water security by guiding global freshwater resource preservation.
Overexpression of PRL7D1 in Leydig Cells Causes Male Reproductive Dysfunction in Mice
Authors: Liu Yaping , Su Xingyu , Hao Jie , Chen Maoxin , Liu Weijia , Liao Xiaogang , Li Gang
Published: January 2016

Prolactin family 7, subfamily d, member 1 (PRL7D1) is found in mouse placenta. Our recent work showed that PRL7D1 is also present in mouse testis Leydig cells, and the expression of PRL7D1 in the testis exhibits an age-related increase. In the present study, we generated transgenic mice with Leydig cell-specific PRL7D1 overexpression to explore its function during male reproduction. Prl7d1 male mice exhibited subfertility as reflected by reduced sperm counts and litter sizes. The testes from Prl7d1 transgenic mice appeared histologically normal, but the frequency of apoptotic germ cells was increased. Prl7d1 transgenic mice also had lower testosterone concentrations than wild-type mice. Mechanistic studies revealed that Prl7d1 transgenic mice have defects in the testicular expression of steroidogenic acute regulatory protein (STAR) and hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase cluster (HSD3B). Further studies revealed that PRL7D1 overexpression affected the expression of transferrin (TF) in Sertoli cells. These results suggest that PRL7D1 overexpression could lead to increased germ cell apoptosis and exert an inhibitory effect on testosterone production in Leydig cells by reducing the expression of certain steroidogenic-related genes. In addition, PRL7D1 appears to have important roles in the function of Sertoli cells, which, in turn, affects male fertility. We conclude that the expression level of PRL7D1 is associated with the reproductive function of male mice.
Study on Sintering Mechanism of Stainless Steel Fiber Felts by X-ray Computed Tomography
Authors: Ma Jun , Li Aijun , Tang Huiping
Published: January 2016

The microstructure evolution of Fe-17 wt. % Cr-12 wt. % Ni-2 wt. % Mo stainless steel fiber felts during the fast sintering process was investigated by the synchrotron radiation X-ray computed tomography technique. The equation of dynamics of stable inter-fiber neck growth was established for the first time based on the geometry model of sintering joints of two fibers and Kucsynski’s two-sphere model. The specific evolutions of different kinds of sintering joints were observed in the three-dimensional images. The sintering mechanisms during sintering were proposed as plastic flow and grain boundary diffusion, the former leading to a quick growth of sintering joints.
Seed Burial Depth and Soil Water Content Affect Seedling Emergence and Growth of Ulmus pumila var. sabulosa in the Horqin Sandy Land
Authors: Tang Jiao , Busso Carlos , Jiang Deming , Wang Yongcui , Wu Dafu , Musa Ala , Miao Renhui , Miao Chunping
Published: January 2016

We investigated the effects of seed burial depth and soil water content on seedling emergence and growth of Ulmus pumila var. sabulosa (sandy elm), an important native tree species distributed over the European-Asian steppe. Experimental sand burial depths in the soil were 0.5, 1.0, 1.5, 2.0 and 2.5 cm, and soil water contents were 4%, 8%, 12% and 16% of field capacity. All two-way ANOVA (five sand burial depths and four soil water contents) results showed that seed burial depths, soil water content and their interactions significantly affected all the studied plant variables. Most of the times, seedling emergence conditions were greater at the lower sand burial depths (less than 1.0 cm) than at the higher (more than 1.0 cm) seed burial depths, and at the lower water content (less than 12%) than at the higher soil water content. However, high seed burial depths (more than 1.5 cm) or low soil water content (less than 12%) reduced seedling growth or change in the root/shoot biomass ratios. In conclusion, the most suitable range of sand burial was from 0.5 to 1.0 cm soil depth and soil water content was about 12%, respectively, for the processes of seedling emergence and growth. These findings indicate that seeds of the sandy elm should be kept at rather shallow soil depths, and water should be added up to 12% of soil capacity when conducting elm planting and management. Our findings could help to create a more appropriate sandy elm cultivation and understand sparse elm woodland recruitment failures in arid and semi-arid regions.
The Optimal Dispatch of a Power System Containing Virtual Power Plants under Fog and Haze Weather
Authors: Gao Yajing , Cheng Huaxin , Zhu Jing , Liang Haifeng , Li Peng
Published: January 2016

With the growing influence of fog and haze (F-H) weather and the rapid development of distributed energy resources (DERs) and smart grids, the concept of the virtual power plant (VPP) employed in this study would help to solve the dispatch problem caused by multiple DERs connected to the power grid. The effects of F-H weather on photovoltaic output forecast, load forecast and power system dispatch are discussed according to real case data. The wavelet neural network (WNN) model was employed to predict photovoltaic output and load, considering F-H weather, based on the idea of “similar days of F-H”. The multi-objective optimal dispatch model of a power system adopted in this paper contains several VPPs and conventional power plants, under F-H weather, and the mixed integer linear programming (MILP) and the Yalmip toolbox of MATLAB were adopted to solve the dispatch model. The analysis of the results from a case study proves the validity and feasibility of the model and the algorithms.

Périgueux : la population, l'urbanisation récente et ses problèmes
Authors: Di Méo Guy
Published: January 2016

Vieillie, la population de Périgueux diminue depuis dix ans. Dans un contexte économique marqué par la chute des emplois industriels la zone urbanisée s'est cependant étendue, notamment aux sorties est et ouest de la ville et l'on peut parler de banlieue. Une véritable ségrégation sociale s'opère : le vieux centre, en partie remodelé et consacré aux activités de services, devient aussi une zone de résidence aisée tandis que les zones pavillonnaises et les groupes d'immeubles collectifs périphériques accueillent les habitants disposant de revenus moyens ou faibles sans pouvoir leur offrir tous les équipements socio-éducatifs souhaitables.
Les dépressions d'évidement du Massif Central méridional
Authors: Enjalbert Henri
Published: January 2016

The author investigates four spots in the southern part of the french Massif Central which are characterised by the outcropping of soft rocks. These are the district of Celles-Liausson, near Lodève, the valley of river Serre through the Causse of Sévérac, the district of the Pradailles in the Camarès basin, and the vale of Ady, west of Rodez. These are large depressed areas that were hollowed out and are nowadays overlooked by the table-like heights made in hard rocks around them. In order to explain their formation, the author considers that orogenic movements have « prepared » the bedrock and that hydro-eolian processus have then hollowed these areas. The hollowing is attributed a mindelian age. These relief features are actually overstanding the valleys and their development is stopped.
Tourisme et vie urbaine dans l'agglomération d'Arcachon
Authors: Cassou-Mounat Micheline
Published: January 2016

Résumé. — La commune d'Arcachon fut détachée de La Teste en 1857. La fin du siècle vit se développer la ville basse au plan en damier et une ville d'hiver dans les dunes boisées. La fonction climatique a fait place à une fonction balnéaire estivale. Dans la période contemporaine, les lotissements s'étendent, vers le sud, au Moulleau et au Pyla. L'urbanisation gagne ensuite les villages de pêcheurs de La Teste et de Gujan ; puis des constructions nouvelles commencent à rénover le centre urbain. L'ostréiculture et la construction navale de plaisance restent les activités permanentes principales, dans une agglomération de 40000 habitants où le niveau d'emploi est médiocre et, en conséquence, la mobilité de la population très grande. L'influence directe de l'agglomération bordelaise est considérable.
Croissance et avenir des villes moyennes françaises

Les villes moyennes françaises — un tiers de la population urbaine totale du pays — croissent à un taux particulièrement rapide. Moyennement industrielles, elles sont caractérisées par un dynamisme du secteur tertiaire et de la construction induits par le rattrapage des équipements publics et l'élévation du niveau de consommation. Elles ont tendance à se séparer de « leur » région et à s'intégrer toujours plus dans le système économico-politique national et international. Mais elles restent soumises à la double contrainte d'une organisation médiocre des services et de l'étroitesse de leur marché du travail, qui provoque l'exode urbain.

The water-gaps of the river Aude near Minerve (Aude, France). This analysis of some peculiarities of the river Aude valley in Languedoc is mainly devoted to its defile through the Bassanel anticline. Through evidences from five successive alluvial terraces and the existence of some depressions explained by wind-erosion, the author demonstrates that it was during the final Riss period that the Aude flew through the Bassanel gap which had been previously cut by the Ognon and he explains that the diversion was more facilitated by the previous wind-erosion period than by any neotectonic change of the regional structural geology.

The regional park of the Landes of Gascogne (France). — Situated in the very heart of the pine-tree forest, in the Landes of Gascogne, the regional park covers over 200 thousands hectares along river Eyre, the main tributary of the Bassin of Arcachon, It was created to help and maintain the existing environment which presently suffers from various agressions and to promote a better knowledge of the past rural economy and culture. The park's main focus are the eco-museum of Marquèze, in Sabres, which is devoted to the Grande Lande and its past rural life with a special reference to shepherding ; the eco-museum of pine tar extraction and products in Luxey ; a permanent center devoted to the approach of physical environment and the bird life area of Teich ; then a canoe-kayak station on the river Eyre and a workshop in Saugnac. All villages within the park experiment to day the effects of demographic decrease and decline of the traditional agricultural and forest economy. But when the park can be considered as a support for tourism it has not contributed yet to the renewal of the rural life.

Toulouse est la dernière métropole française à s'être dotée des documents d'urbanisme selon la loi de 1967. Le contenu du Schéma Directeur d'Aménagement et d'Urbanisme et celui des Plans d'Occupation du Sol, encore inachevés, relèvent de la même logique que celui des autres grandes villes françaises. Les plans entérinent des situations acquises ou probables, développent le mythe de l'environnement, tentent d'ordonner par un schéma de circulation et un zonage fonctionnel des activités la croissance spatiale et économique de l'agglomération. Résultats de compromis entre élus locaux représentant les intérêts des classes de la moyenne et petite bourgeoisie, et de techniciens et administrateurs représentant l'État, ces documents esquivent les contradictions entre volonté de planification et processus réels d'urbanisation.

A reconstruction of the Quaternary Ariege glacier in Tarascon basin (Northern Pyrénées). The Pyrenean basin of Tarascon lies within a mountainous district which is more remarkable by its intricated relief and physiography than by its altitudes. It is a fluvial junction and was occupied and scoured by the pleistocene glaciers advancing down from the Ariège and Vicdessos valleys. Many glacial transfluences, diffluences and marginal obturations occurred on the margins of this basin during the glacial phases. Three main phases should be individualized : the pleniglaciaire stage during which altitude of ice reached 1000 m and over ; a long pause phase close to 650-700 m ; and a clear recurrence close to 500 m, which can be correlated with the würmian alluvial deposits, when the two previous phases can be considered as rissian,

Cardiosphere-derived cells (CDCs), which can be isolated from heart explants, are a promising candidate cell source for infarcted myocardium regeneration. However, current protocols used to expand CDCs require at least 1 month in vitro to obtain sufficient cells for transplantation. We report that CDC culture can be optimized by preconditioning the cells under hypoxia (2% oxygen), which may reflect the physiological oxygen level of the stem cell niche. Under hypoxia, the CDC proliferation rate increased by 1.4-fold, generating 6 × 106 CDCs with higher expression of cardiac stem cell and pluripotency gene markers compared to normoxia. Furthermore, telomerase (TERT), cytokines/ligands involved in stem cell trafficking (SDF/CXCR-4), erythro-poiesis (EPO), and angiogenesis (VEGF) were increased under hypoxia. Hypoxic preconditioning was mimicked by treatment with two types of hypoxia-inducible factor (HIF) prolyl-4-hydroxylase inhibitors (PHDIs): dimethyloxaloylglycine (DMOG) and 2-(1-chloro-4-hydroxyisoquinoline-3-carboxamido) acetic acid (BIC). Despite the difference in specificity, both PHDIs significantly increased c-Kit expression and activated HIF, EPO, and CXCR-4. Furthermore, treatment with PHDIs for 24 h increased cell proliferation. Notably, all hypoxic and PHDI-preconditioned CDCs had decreased oxygen consumption and increased glycolytic metabolism. In conclusion, cells cultured under hypoxia could have potentially enhanced therapeutic potential, which can be mimicked, in part, by PHDIs.

Multipotent mesenchymal stromal cells (MSCs) have gained tremendous attention as potential therapeutic agents for the treatment of orthopedic diseases. Promising results have been obtained after application of MSCs for treatment of tendon and joint disease in the equine model, making it appear favorable to use these results as a basis for the translational process of the therapy. However, while the horse is considered a highly suitable model for orthopedic diseases, knowledge is lacking regarding the level of analogy of equine MSCs and their human counterparts. Therefore, the aim of this study was to assess the properties of human and equine adipose-and tendon-derived MSCs in a direct comparison. Basic properties of human and equine MSCs from both tissues were similar. The cells expressed CD29, CD44, CD90, and CD105 and lacked expression of CD73, CD14, CD34, CD45, CD79a, and MCHII/HLA-DR. No significant differences were found between proliferation potential of human and equine MSCs in early passages, but recovery of nucleated cells after tissue digestion as well as proliferation in later passages was higher in equine samples (p < 0.01). All samples showed a good migration capacity and multilineage differentiation potential. However, while osteogenic differentiation was achieved in all equine samples, it was only evident in five out of nine human tendon-derived samples. Human MSCs further showed a higher expression of collagen IIIA1 and tenascin-C, but lower expression of decorin and scleraxis (p < 0.01). Although revealing some potentially relevant differences, the study demonstrates a high level of analogy between human and equine MSCs, providing a basis for translational research in the equine model according to the guidelines issued by the authorities.

Background

Ultrafiltration failure (UFF) diagnosed at the initiation of peritoneal dialysis (PD) has been insufficiently characterized. In particular, few longitudinal studies have analyzed the time course of water transport in patients with this complication.

Objective

To investigate the time course of peritoneal water transport during the first year on PD in patients presenting UFF since the initiation of this therapy (study group).

Method

Prospective, observational, single-center design. We analyzed, at baseline and after 1 year of follow-up, peritoneal water transport in 19 patients incident on PD with UFF. We used incident patients without UFF as a control group. Water transport was characterized with the help of 3.86/4.25% dextrose-based peritoneal equilibration tests (PETs) with complete drainage at 60 minutes.

Results

The study group revealed a disorder of water transport affecting both small-pore ultrafiltration (SPUF) ( p = 0.054 vs incident without UFF) and free water transport (FW T) ( p = 0.001). After 1 year of follow-up, FWT displayed a general increasing trend in the study group (mean variation 48.9 mL, 95% confidence interval [CI] 15.5, 82.2, p = 0.012), while the behavior of SPUF was less predictable (-4.8 mL, 95% CI -61.4, 71.1, p = 0.85). These changes were not observed in incident patients without UFF. Neither initial clinical characteristics, baseline PET-derived parameters, or suffering peritoneal infections during the first year predicted the time course of the capacity of UF in the study group. Recovery from incident UFF was apparently linked to improvement of SPUF.

Conclusions

Patients with UFF at the start of PD suffer a disorder of peritoneal water transport affecting both FWT and SPUF. Free water transport increases systematically in these patients after 1 year of follow-up. The evolution of SPUF is less predictable, and improvement of this parameter marks reversibility of this complication.

The charge behavior of organic light emitting diode (OLED) is investigated by steady-state current–voltage technique and impedance spectroscopy at various temperatures to obtain activation energies of charge injection and transport processes. Good agreement of activation energies obtained by steady-state and frequency-domain was used to analyze their contributions to the charge injection and transport. We concluded that charge is injected into the OLED device mostly through the interfacial states at low voltage region, whereas the thermionic injection dominates in the high voltage region. This comparison of experimental techniques demonstrates their capabilities of identification of major bottleneck of charge injection and transport.

We present the first images of four debris disks observed in scattered light around the young (4–250 Myr old) M dwarfs TWA 7 and TWA 25, the K6 star HD 35650, and the G2 star HD 377. We obtained these images by reprocessing archival Hubble Space Telescope NICMOS coronagraph data with modern post-processing techniques as part of the Archival Legacy Investigation of Circumstellar Environments program. All four disks appear faint and compact compared with other debris disks resolved in scattered light. The disks around TWA 25, HD 35650, and HD 377 appear very inclined, while TWA 7's disk is viewed nearly face-on. The surface brightness of HD 35650's disk is strongly asymmetric. These new detections raise the number of disks resolved in scattered light around M and late-K stars from one (the AU Mic system) to four. This new sample of resolved disks enables comparative studies of heretofore scarce debris disks around low-mass stars relative to solar-type stars.
Visualizing Moderating Effects in Path Models with Latent Variables
Authors: Kock Ned
Published: January 2016

Path models with and without latent variables are extensively used in e-collaboration research. Both direct and moderating relationships can be included in such path models. Moderating relationships involve three latent variables, the moderating variable and a pair of variables that are connected through a direct link. This paper discusses the visualization of moderating relationships through two-dimensional and three-dimensional graphs. The software WarpPLS version 5.0 is used in this discussion, since it provides an extensive set of graphs that can be used to visualize moderating effects.
