Responsabilité sociale d’entreprise et identité du dirigeant : une réflexion sur les petits entrepreneurs en Afrique

This article applies the responsibility of the person to the case of small entreprises in Africa. The notion of identity is central to the analysis. Indeed it enables to understand that community involvement of managers is not primarily a strategic behavior but rather a way to be coherent with their practical identity. Senegal is an example of this. However this social responsibility of the person is different from social responsibility of large companies. It is therefore necessary to look at the consequences of social responsibility standards on the weakening of small entreprises.
The nature of powerful compact radio galaxies

Three compact powerful radio galaxies, PKS 1353 341, PKS 1814 637 and PKS 1934 638, have been imaged. The three galaxies seem to be giant ellipticals, the last two being bluer than normal gEs by 0.2-0.3 mag in B I, which is expected if they are the result of recent merging. HI absorption has been detected in all three objects with very different characteristics. The broad absorption in PKS 1353 341 probably takes place in a torus or a disk with a radius of at least a few tens of pc. For PKS 1814 637 the principal absorption is less broad and the disk radius more likely a few hundreds of pc. The absorption in PKS 1934 638 is very narrow and is probably due to gas not directly connected to the central engine.
The Relationship Between Symptoms of Attention Deficit Hyperactivity Disorder and Impairment in High School Students

ZOROMSKI, ALLISON K. , M.S., June 2012, Psychology The Relationship Between Symptoms of Attention Deficit Hyperactivity Disorder and Impairment in High School Students (124 pp.) Director of Thesis: Steven W. Evans The relationship between symptoms of ADHD and impairment has been investigated in children and adults with ADHD (e.g., Barkley et al., 2006), but this relationship has not been well studied in adolescents. Results of recent studies investigating the relationship between symptoms and impairment in children have indicated that symptoms of ADHD and impairment may not be as related as once thought. Understanding the relationship between impairment and symptoms for adolescents with ADHD can provide important information for assessment, treatment development and the prescribing of interventions. The purpose of this study was to examine the correspondence between ADHD symptoms and impairment in adolescents as rated by high school teachers. Differences in impairment between students who teachers identify as having high levels of inattention, hyperactivity/impulsivity, or a combination of these symptoms were examined. Additionally, the symptoms that best predicted various domains of impairment were investigated. The results indicated that based on ratings provided by high school teachers symptoms of inattention are more related to impairment than symptoms of hyperactivity/impulsivity across multiple domains. Second, data from high school teachers’ ratings indicate that there is considerable variability in the relationship between specific symptoms and impairment in each domain
Keyword-aware continuous kNN query on road networks

It is nowadays quite common for road networks to have textual contents on the vertices, which describe auxiliary information (e.g., business, traffic, etc.) associated with the vertex. In such road networks, which are modelled as weighted undirected graphs, each vertex is associated with one or more keywords, and each edge is assigned with a weight, which can be its physical length or travelling time. In this paper, we study the problem of keyword-aware continuous k nearest neighbour (KCkNN) search on road networks, which computes the k nearest vertices that contain the query keywords issued by a moving object and maintains the results continuously as the object is moving on the road network. Reducing the query processing costs in terms of computation and communication has attracted considerable attention in the database community with interesting techniques proposed. This paper proposes a framework, called a Labelling AppRoach for Continuous kNN query (LARC), on road networks to cope with KCkNN query efficiently. First we build a pivot-based reverse label index and a keyword-based pivot tree index to improve the efficiency of keyword-aware k nearest neighbour (KkNN) search by avoiding massive network traversals and sequential probe of keywords. To reduce the frequency of unnecessary result updates, we develop the concepts of dominance interval and region on road network, which share the similar intuition with safe region for processing continuous queries in Euclidean space but are more complicated and thus require more dedicated design. For high frequency keywords, we resolve the dominance interval when the query results changed. In addition, a path-based dominance updating approach is proposed to compute the dominance region efficiently when the query keywords are of low frequency. We conduct extensive experiments by comparing our algorithms with the state-of-the-art methods on real data sets. The empirical observations have verified the superiority of our proposed solution in all aspects of index size, communication cost and computation time.
Fast Multi-Feature Image Retrieval using Dominant Colour, Logical Edge and Binarization Techniques

Modern web era has lots of multimedia contents to share on social networking websites, emails, video and photo sharing portals, chat tools, and these are going faster and faster day by day due to easy availability of internet and high quality digital cameras in every hand. As a result the servers have a large collection of these multimedia contents especially images and to extract out the desired image from such large collection is tough and complex task. Everyone in this world has different need and desire to search images for their need. In this paper a fast multi-feature image retrieval technique is proposed which is based on dominant colour method for colour feature extraction, Logical Edge for texture extraction and binarization for shape feature extraction.
A novel aberrant splice site mutation in the APC gene

Familial adenomatous polyposis (FAP) is an inherited, autosomal dominant syndrome characterised by the presence of multiple (>100) adenomatous polyps in the colon and rectum. These polyps, if left untreated, progress to colorectal cancer (CRC), typically by the age of 40 years.1 Other clinical features include variable age of onset of polyposis (age 10-40 years) and variable expression.2 FAP accounts for about 1% of all colorectal cancers.3,4 In addition to colonic polyps, FAP patients may present premalignant lesions in the upper gastrointestinal tract, extraintestinal manifestations such as osteomas and epidermoid cysts, desmoid formation, congenital hypertrophy of the retinal pigment epithelium (CHRPE), and other malignant changes, such as small bowel cancer and tumours of the brain and thyroid gland.2 FAP is caused by the dominant inheritance of germline mutations of the adenomatous polyposis coli (APC, MIM 175100) tumour suppressor gene.3–6 APC is a 312 kDa protein translated from a major transcript consisting of 15 exons with the last exon occupying 77% of the total protein. Additional APC transcripts occur because of alternative splicing of exons 3-4, 9, 10A/X, and 14.7–9 The majority of APC mutations result in the formation of a truncated protein10 and most germline mutations are reported in the first half of the gene.11–13 Mutant APC proteins lack the potentially important functional motifs including binding domains for β-catenin, microtubulin, and EB1.14–16 Furthermore, the armadillo repeats are located between APC exons 10-14, and deletion of this domain disrupts interactions between APC and other partner proteins including PP2A and ASEF.17,18 The GT and AG sequence motifs are highly conserved consensus splice donor and acceptor site sequences at the intron-exon boundaries.19,20 Splice site defects account for approximately 15% of disease causing point mutations of various …
Fillers as Functional Categories:Evidence from German-English Bilingual Acquisition

During the acquisition period, some children go through a stage in which they produce monosyllabic segments that cannot be associated with any existing words. Phonetically, these so-called filler syllables [FILL] typically consist of vocalic segments, mainly [ə,e,a]: “rather than being associated with a specific phonetic feature, [they] are realized within a phonetic space, the low-central area” (Bottari, Cipriani & Chilosi 1993/94: 331). Fillers normally emerge during the child’s transition from the oneto the two-word stage, appearing before lexical elements of various types (see (1)), and tend to disappear with the emergence of free functional morphemes (see Peters (2001) for an overview).
RoboCup Rescue: search and rescue in large-scale disasters as a domain for autonomous agents research

Disaster rescue is one of the most serious social issue which involves very large numbers of heterogeneous agents in the hostile environment. RoboCup-Rescue intends to promote research and development in this socially significant domain by creating a standard simulator and forum for researchers and practitioners. While the rescue domain intuitively appealing as large scale multi-agent domains, it has not yet given through analysis on its domain characteristics. In this paper, we present detailed analysis on the task domain and elucidate characteristics necessary for multi-agent systems for this domain.
Procedure Time for Gastric Endoscopic Submucosal Dissection according to Location, considering Both Mucosal Circumferential Incision and Submucosal Dissection

Background. Previous assessments of technical difficulty and procedure time for endoscopic submucosal dissection (ESD) of gastric neoplasms did not take into account several critical determinants of these parameters. However, two key phases of ESD determine the total procedure time: the mucosal circumference incision speed (CIS) and submucosal dissection speed (SDS). Methods. We included 302 cases of en bloc and R0 resection of gastric neoplasms performed by 10 operators who had completed the training program at our hospital. Twelve locations were classified based on multiple criteria, such as condition of surrounding mucosa, lesion vascularity, presence of submucosal fat, ulcers, scars, fibrosis, and scope and device maneuverability. Lesions in different locations were classified into three groups based on the length of the procedure: fast, moderate, or late. Results. A significant difference was found in CIS and SDS for each location (p < 0.01), which demonstrates the validity of this classification system. In several locations, CIS and SDS were not consistent with each other. Conclusion. CIS and SDS did not correspond to each other even for lesions in the same location. Consideration of ESD procedure time for gastric neoplasms requires a more elaborate classification system than that previously reported.
Mobile information and entertainment services: business models and service networks

The mobile telecommunications industry is undergoing a rapid change, which is increasing the interdependency of firms in the sector. This trend increases the likelihood that mobile information and entertainment services will be delivered through inter-organisational networks of firms. These networks are the topic of this research. In particular, we examine service networks and the possible influence of business models on their characteristics. Using data from five case studies of mobile service networks, we examine the influence of revenue models and network membership benefits on network characteristics. The results of this exploratory research demonstrate that revenue models have a relationship with governance and that both revenue sharing agreements and governance mechanisms become less standardised with greater distance from the end user. In the conclusion we discuss the implications of these findings for research on both inter-firm service networks and business models.
Uterine glycogen metabolism in mink during estrus, embryonic diapause and pregnancy

We have determined uterine glycogen content, metabolizing enzyme expression and activity in the mink, a species that exhibits obligatory embryonic diapause, resulting in delayed implantation. Gross uterine glycogen concentrations were highest in estrus, decreased 50% by diapause and 90% in pregnancy (P ≤ 0.05). Endometrial glycogen deposits, which localized primarily to glandular and luminal epithelia, decreased 99% between estrus and diapause (P ≤ 0.05) and were nearly undetectable in pregnancy. Glycogen synthase and phosphorylase proteins were most abundant in the glandular epithelia. Glycogen phosphorylase activity (total) in uterine homogenates was higher during estrus and diapause, than pregnancy. While glycogen phosphorylase protein was detected during estrus and diapause, glycogen synthase was almost undetectable after estrus, which probably contributed to a higher glycogenolysis / glycogenesis ratio during diapause. Uterine glucose-6-phosphatase 3 gene expression was greater during diapause, when compared to estrus (P ≤ 0.05) and supports the hypothesis that glucose-6-phosphate resulting from phosphorylase activity was dephosphorylated in preparation for export into the uterine lumen. The relatively high amount of hexokinase-1 protein detected in the luminal epithelia during estrus and diapause may have contributed to glucose trapping after endometrial glycogen reserves were depleted. Collectively, our findings suggest to us that endometrial glycogen reserves may be an important source of energy, supporting uterine and conceptus metabolism up to the diapausing blastocyst stage. As a result, the size of uterine glycogen reserves accumulated prior to mating may in part, determine the number of embryos that survive to the blastocyst stage, and ultimately litter size.

Emergence of singular structures in Oldroyd-B fluids

Numerical simulations reveal the formation of singular structures in the polymer stress field of a viscoelastic fluid modeled by the Oldroyd-B equations driven by a simple body force. These singularities emerge exponentially in time at hyperbolic stagnation points in the flow and their algebraic structure depends critically on the Weissenberg number. Beyond a first critical Weissenberg number the stress field approaches a cusp singularity, and beyond a second critical Weissenberg number the stress becomes unbounded exponentially in time. A local approximation to the solution at the hyperbolic point is derived from a simple ansatz, and there is excellent agreement between the local solution and the simulations. Although the stress field becomes unbounded for a sufficiently large Weissenberg number, the resultant forces of stress grow subexponentially. Enforcing finite polymer chain lengths via a FENE-P penalization appears to keep the stress bounded, but a cusp singularity is still approached exponentially in time.
X-Ray and Optical Variations in the Classical Be Star γ Cassiopeia: The Discovery of a Possible Magnetic Dynamo

The classical B0.5e star γ Cassiopeia is known to be a unique X-ray source by virtue of its moderate LX (1033 ergs s-1), hard X-ray spectrum, and light curve punctuated by ubiquitous flares and slow undulations. The peculiarities of this star have led to a controversy concerning the origin of these emissions: whether they are from wind infall onto a putative degenerate companion, as in the case of normal Be/X-ray binaries, or from the Be star itself. Recently, much progress has been made to resolve this question: (1) the discovery that γ Cas is a moderately eccentric binary system (P = 203.59 days) with unknown secondary type, (2) the addition of RXTE observations at six epochs in 2000, adding to three others in 1996-1998, and (3) the collation of robotic telescope (Automated Photometric Telescope) B- and V-band photometric observations over four seasons that show a 3%, cyclical flux variation with cycle lengths of 55-93 days. We find that X-ray fluxes at all nine epochs show random variations with orbital phase, thereby contradicting the binary accretion model, which predicts a substantial modulation. However, these fluxes correlate well with the cyclical optical variations. In particular, the six flux measurements in 2000, which vary by a factor of 3, closely track the interpolated optical variations between the 2000 and 2001 observing seasons. The energy associated with the optical variations greatly exceeds the energy in the X-rays, so that the optical variability cannot simply be due to reprocessing of X-ray flux. However, the strong correlation between the two suggests that they are driven by a common mechanism. We propose that this mechanism is a cyclical magnetic dynamo excited by a Balbus-Hawley instability located within the inner part of the circumstellar disk. According to our model, variations in the field strength directly produce the changes in the magnetically related X-ray activity. Turbulence associated with the dynamo results in changes to the density (and therefore the emission measure) distribution within the disk and creates the observed optical variations.
The Natural Environmental Strategies of International Firms: Old Controversies and New Evidence on Performance and Disclosure

Previous academic and popular literature has raised important debates concerning the contradictory incentives for international firms to reduce their environmental impacts and offer transparent environmental information about their operations. As an exhaustive review of this literature revealed mixed and partial evidence, we compared the individual corporate environmental performance and disclosure of the 100 most international nonfinancial firms in the world to those of 16,023 firms in their industries and a group of selected firms similar to those in the group of the 100 most international in our sample. Our results show that although the top international firms have a much better record of environmental disclosure than the firms within their industries and the matched pairs, the top international firms actually show worse environmental performance than their peers. The results suggest that the top international firms seek legitimation for their environmental activities by means of voluntary disclosure.
Fetal hormonal programming of sex differences in depression: linking women's mental health with sex differences in the brain across the lifespan

Women’s health has traditionally beenthoughtofintherealmofreproduc-tive health, and that includes women’smental health (i.e., perinatal psychiatry). However, we now know there are sig-niﬁcant sex differences in many chronicdiseases, including brain disorders. Thus,understanding the causes of sex differ-ences in disorders of the brain, withinand outside of reproduction, is criticalto understanding women’s mental healthand healthcare needs. In order to accom-plish this, it is necessary for neuroscienceto adopt a “sex-dependent” and/or “sex-speciﬁc” lens on investigations of thebrain. In this review, we make the case fordepression, which has among the largestsex differences in disorders of the brain.Major depressive disorder (MDD)recently became the number one cause ofdisability worldwide (Murray and Lopez,1997; Ustun et al., 2004; World HealthOrganization, 2012). Importantly, theincidence of MDD in women is twicethat of men (Kessler, 2003; Kendler et al.,2006), and thus understanding its patho-physiology has widespread implicationsfor attenuation and prevention of dis-ease burden, particularly in women. Over40 years of research implicate hormonaldysregulation underlying mood disorders(Boardetal.,1956;GibbonsandMcHugh,1962; Coplan et al., 2000; Brouwer et al.,2005; Kurt et al., 2007; Barim et al., 2009),particularlyinvolvementofhypothalamic-pituitary-adrenal (HPA) and HP-gonadal(HPG) axes (Board et al., 1956; Gibbonsand McHugh, 1962; Plotsky et al., 1998;Young and Korszun, 2002; Swaab et al.,2005). Central dysregulation of hormonalaxes can precede MDD onset suggest-ing a role for hormonal abnormalitiesin female MDD vulnerability. Ours andothers’ work demonstrated that the vul-nerabilityforsex-dependentriskforMDDbegins in
Communication in social networking websites. Development of social bonds or polarization of political views

New media are frequently used for presenting views and developing desired socio-political opinions. The social networking websites are becoming an objection towards the use of media messages as tools of persuasion and manipulation. However, they are not playing that role completely. The article discusses the process of developing social capital in social networking websites, against the background of social relationships based on trust or lack of trust. Partnership and cooperation are becoming important tools of democracy, with which there are constructed the social bonds which mobilize the users of media networking websites to undertake political activities. The developed social bonds constitute a source of discussion groups concentrated around joint views. In turn, in the light of lack of trust, that division into groups leads to alienation and the resulting polarization of views. The polarization tendencies in the social networking media limit their informative character. At the same time, they cause a situation when, in the social networking area of the Internet, different socio-political activities are ignored or blocked. Media education is to counteract such tendencies. Under the European law, the European countries have been obliged to develop media education both in education, and through social educational programs. The current condition of media education in Poland was presented.
