AbstractPolychlorinated biphenyls (PCBs) and dioxins (PCDDs/Fs) are well-known endocrine disrupters. This paper strives to elucidate the data on reproductive consequences of perinatal dioxin and PCB exposure in men and women. We focused on the following end-points: sex-ratio, endometriosis, menstrual cycle characteristics, sperm quality, and prematurity. We summarize 46 papers and compare their results including effects seen after exposure to background concentrations. Seven of twelve studies showed a decrease in sex-ratio after parental dioxin or PCB exposure. In three of the seven studies, effects were seen after paternal exposure and in three after maternal exposure. In eight of the nine studies on menstrual cycle characteristics, abnormalities were associated with PCB or dioxin exposure, however the results differed. In three studies PCB and TCDD were associated with longer menstrual cycles, while three studies indicated that an increase in PCB/PCDF exposure was associated with shorter cycles. Five studies showed effects on menstrual bleeding with higher PCB or dioxin exposure. A higher rate of irregular menstrual cycles in exposed women was seen in four studies. The conflicting outcomes probably result from variability in study design, timing of exposure and endocrine disrupting properties of the measured congeners. Nine of sixteen studies detected higher PCB or dioxin exposure in women with endometriosis. However, the manner of diagnosing endometriosis and the character of the studies varied from prospective to retrospective. Five of eight studies focusing on sperm quality showed that men, with higher serum concentrations of PCBs and/or PCB congeners and/or PCDFs, had reduced sperm quality, including increased abnormal morphology and reduced motility. The exposure timeframe seemed important here. There are two studies addressing preterm birth in relation to PCBs, one mentioned a shortening of three days of gestational age, two other studies did not find a relation. Recently one study related a shorter gestational age of half a week with overall dioxin activity measured with the CALUX method in cord blood, particularly in boys. In conclusion, exposure to PCBs and dioxins has a negative effect on the reproductive systems of human populations. Although some speculations have been made, the exact mechanism of these effects and the interactions of these compounds with other endocrine disruptors are not yet known. Age at exposure and congener specific properties are probably crucial in interpreting the observed results.
The influence of perinatal and current dioxin and PCB exposure on puberty: a review

AbstractOver the last two decades much has been
written about the consequences of perinatal dioxin
and PCB exposure in humans. In this paper we strive
to elucidate the data on puberty in relation to these
endocrine disruptive compounds in human populations.
Effects in PCB/dioxin-exposed human populations on
puberty are seen, not only in highly exposed cohorts, but
also in average populations with background exposures.
Study showed effects like increased weight, a delay
in pubic hair growth and male genital development in
boys, sex-hormone homeostasis, reduced penile length,
and delayed age at first ejaculation after PCB exposure.
Effects seen after dioxin exposure include retarded
initiation and stage of breast development in girls, earlier
menarche, disruption of sex hormone homeostasis,
reduced testicular volume and reduced penile length
in boys. The data published by different studies were
inconclusive as a result of different methodological
setup as well as because of multiple exposure settings.
Populations were exposed to different mixtures of
dioxin/PCB congeners or mixtures with other endocrine
disrupters, and therefore synergistic and antagonistic
effects with PCBs and dioxins are possible. Dioxinlike
compounds disturb the hormonal balance mainly through interaction with the Ah receptor, which may
influence the synthesis of hormones or their transport
proteins. However, we have to keep in mind that
hormonal balance during puberty could also be altered
by disruption of the thyroid homeostasis. Another
important possible mechanism is the induction of
epigenetic changes or effects on genetic polymorphism.
The fact that exposure to background concentrations of
dioxin-like compounds and PCBs also has effects on the
reproductive development is disconcerting and warrants
further research and long term follow-up studies.
On weighted total least squares adjustment for solving the nonlinear problems
Authors: Hu C. , Chen Y. , Peng Y. 
Published: June 2014

Abstract
In the classical geodetic data processing, a non- linear problem always can be converted to a linear least squares adjustment. However, the errors in Jacob matrix are often not being considered when using the least square method to estimate the optimal parameters from a system of equations. Furthermore, the identity weight matrix may not suitable for each element in Jacob matrix. The weighted total least squares method has been frequently applied in geodetic data processing for the case that the observation vector and the coefficient matrix are perturbed by random errors, which are zero mean and statistically in- dependent with inequality variance. In this contribution, we suggested an approach that employ the weighted total least squares to solve the nonlinear problems and to mitigate the affection of noise in Jacob matrix. The weight matrix of the vector from Jacob matrix is derived by the law of nonlinear error propagation. Two numerical examples, one is the triangulation adjustment and another is a simulation experiment, are given at last to validate the feasibility of the developed method.
Consuming Familiarity and Alterity in Domestic Space
Authors: Slettemeås Dag 
Published: June 2014

Abstract
The present article addresses how stereotyped constructions of migrants’ television behaviour should be contrasted with empirical investigations into the perceptions and articulated practices of migrants themselves. In order to do this, the article explores how 20 migrant households in Norway make sense of television and TV-related activities in their everyday lives. The analysis, employing the domestication theoretical framework, reveals that TV consumption is a multi-faceted and situationally contingent phenomenon. The “practicing of television” goes beyond the mere viewing of programmes based on ethnic origin. Although transnational broadcasts are important, they are neither uncritically domesticated nor sufficient in creating a sense of stability and belonging for migrant families. Rather, it is television as a total experience that proves to be a crucial element in home construction. The domestication theory offers an analytical framework that allows for the dynamics of household relations to be properly articulated, including the embedding of television within household moral economies
Nation-building, not “Resistance Radio”

Abstract
Saami media are an important, if not invaluable, part of Saami society recognized as both a right and a service to the Saami people. In fact, the role of media and media outlets has often been referenced as a manifestation of self determination. However, whereas other Indigenous and ethnic minority media often seek clear financial independence from the state, my research shows that the Saami have a more nuanced and complicated approach. Based primarily on 25 in-depth interviews with Saami journalists, journalism educators and others who have been involved with communication I shed light on the evolving, robust and at times contested understandings of self determination as articulated, justified and practiced by Saami media makers. I argue that by not conflating self-determination with financial independence, Saami media practitioners are engaged in an evolving understanding and practice of media and self determination

Published: June 2014

AbstractSOSORT is an international scientific society interested in spinal deformities, including idiopathic scoliosis (IS). One of the main tasks of the society is to provide diagnostic and therapeutic recommendations for all professionals involved in the conservative treatment of patients with IS.As a part of treatment of scoliosis we distinguished conservative and surgical treatment. The main purpose of the conservative treatment is to stop the progression of the curvature. The aim of the therapy is to improve the quality of life, improve the aesthetics and physical capacity as well. An important element of the conservative treatment is thephysiotherapy, which can be used as independent part of treatment and as a support of brace and the surgical treatment. SOSORT recommends the use of physiotherapy in the form of Physiotherapeutic Specific Exercises (PSE) and the Special Inpatient Rehabilitation (SIR). PSE used in patients with SI must have confirmed efficacy according to the requirements ofthe Evidence Based Medicine. Moreover, the therapy should be selected individually and include: (1) three dimensional auto-correction of deformation, (2) training in activities of daily living, (3) stabilizing the corrected posture, and (4) education of the patient and her/his parents. SIR based on 3-4-week hospital or sanatorium stay is recommended especially at the beginning of the treatment process.Physiotherapists undertaking the work with children with IS should: (1) be qualified in the use of PSE, (2) have adequate experience in techniques used in pediatric orthopedics, (3) have the ability to analyze the variability of body posture during development, (4) have the ability to exercise choice depending on the stages of formation of motor skills, and (5)work in the therapeutic team led by physician supervising the treatment.
Daylighting on the working plane in oriented attic rooms under overcast and clear sky
Authors: Kondáš Kristián , Darula Stanislav 
Published: June 2014

Abstract
The evaluation of daylight conditions in building interiors is based on the Daylight Factor concept after current Slovak standards. Criteria and requirements determined in these standards consider the worst daylight exterior conditions which are described by CIE overcast sky model. The sky luminance distribution of overcast sky is centrical to the zenith, so independence of window orientation to cardinal points is characteristic in daylighting calculations. The sky luminance distribution modelling is one of the main task of the daylight source research more than 50 years. It is evident that also other types of sky conditions exist in nature. An introduction of a new criterion based on photometric variables, which also consider sunlight influence, is expected. This article represents a study of the influence of the interior orientation on distribution of daylighting in attic spaces under an overcast and clear sky

Zygmunt Miłkowski (1824–1915) w powstaniu styczniowym 1863 roku/ Zygmunt Miłkowski’s (1824–1915) involvement in the January Uprising in 1863
Authors: Willaume Małgorzata J. 
Published: June 2014

AbstractZygmunt Miłkowski (Teodor Tomasz Jeż) was a gifted writer who struggled actively in fights for independence of Poland. Among others, he took part in the last Polish uprising against Russia in the 19th century. For a short time he was a leader of the Polish armed forces in Rus. After his resignation from the post he was ordered to organize Polish armed forces in Podolia. One of his ideas was so-called Moldavian expedition. This well-known event described by Miłkowski in his memoirs ended with the struggle with Romanian soldiers near Kostangalia (July 15, 1863). Having won the battle, the Poles were trying to cross the Prut river but had to surrender to Romanians. For a long time Miłkowski tried to explain why this plan failed and why his expedition did not succeed.

Dual Function of CD70 in Viral Infection: Modulator of Early Cytokine Responses and Activator of Adaptive Responses
Authors: Allam Atef , Swiecki Melissa , Vermi William , Ashwell Jonathan D. , Colonna Marco 
Published: June 2014

Abstract
The role of the TNF family member CD70 in adaptive T cell responses has been intensively studied, but its function in innate responses is still under investigation. In this study, we show that CD70 inhibits the early innate response to murine CMV (MCMV) but is essential for the optimal generation of virus-specific CD8 T cells. CD70−/− mice reacted to MCMV infection with a robust type I IFN and proinflammatory cytokine response. This response was sufficient for initial control of MCMV, although at later time points, CD70−/− mice became more susceptible to MCMV infection. The heightened cytokine response during the early phase of MCMV infection in CD70−/− mice was paralleled by a reduction in regulatory T cells (Treg). Treg from naive CD70−/− mice were not as efficient at suppressing T cell proliferation compared with Treg from naive wild-type mice, and depletion of Treg during MCMV infection in Foxp3–diphtheria toxin receptor mice or in wild-type mice recapitulated the phenotype observed in CD70−/− mice. Our study demonstrates that although CD70 is required for the activation of the antiviral adaptive response, it has a regulatory role in early cytokine responses to viruses such as MCMV, possibly through maintenance of Treg survival and function.
The Peritrophic Matrix Mediates Differential Infection Outcomes in the Tsetse Fly Gut following Challenge with Commensal, Pathogenic, and Parasitic Microbes
Authors: Weiss Brian L. , Savage Amy F. , Griffith Bridget C. , Wu Yineng , Aksoy Serap 
Published: June 2014

Abstract
The insect gut is lined by a protective, chitinous peritrophic matrix (PM) that separates immunoreactive epithelial cells from microbes present within the luminal contents. Tsetse flies (Glossina spp.) imbibe vertebrate blood exclusively and can be exposed to foreign microorganisms during the feeding process. We used RNA interference–based reverse genetics to inhibit the production of a structurally robust PM and then observed how this procedure impacted infection outcomes after per os challenge with exogenous bacteria (Enterobacter sp. and Serratia marcescens strain Db11) and parasitic African trypanosomes. Enterobacter and Serratia proliferation was impeded in tsetse that lacked an intact PM because these flies expressed the antimicrobial peptide gene, attacin, earlier in the infection process than did their counterparts that housed a fully developed PM. After challenge with trypanosomes, attacin expression was latent in tsetse that lacked an intact PM, and these flies were thus highly susceptible to parasite infection. Our results suggest that immunodeficiency signaling pathway effectors, as opposed to reactive oxygen intermediates, serve as the first line of defense in tsetse’s gut after the ingestion of exogenous microorganisms. Furthermore, tsetse’s PM is not a physical impediment to infection establishment, but instead serves as a barrier that regulates the fly’s ability to immunologically detect and respond to the presence of these microbes. Collectively, our findings indicate that effective insect antimicrobial responses depend largely upon the coordination of multiple host and microbe-specific developmental factors.

Abstract
Increasing evidence indicates that cancer cell stress induced by chemotherapeutic agents promote antitumor immune responses and contribute to their full clinical efficacy. In this article, we identify the signaling events underlying chemotherapy-induced NKG2D and DNAM-1 ligand expression on multiple myeloma (MM) cells. Our findings indicate that sublethal doses of doxorubicin and melphalan initiate a DNA damage response (DDR) controlling ligand upregulation on MM cell lines and patient-derived malignant plasma cells in Chk1/2-dependent and p53-independent manner. Drug-induced MICA and PVR gene expression are transcriptionally regulated and involve DDR-dependent E2F1 transcription factor activity. We also describe the involvement of changes in the redox state in the control of DDR-dependent upregulation of ligand surface expression and gene transcriptional activity by using the antioxidant agent N-acetyl-l-cysteine. Finally, in accordance with much evidence indicating that DDR and oxidative stress are major determinants of cellular senescence, we found that redox-dependent DDR activation upon chemotherapeutic treatment is critical for MM cell entry in premature senescence and is required for the preferential ligand upregulation on senescent cells, which are preferentially killed by NK cells and trigger potent IFN-γ production. We propose immunogenic senescence as a mechanism that promotes the clearance of drug-treated tumor cells by innate effector lymphocytes, including NK cells.

We present an application to the case of pseudo orbits in some neighborhood of a normally hyperbolic set.
L’intention entrepreneuriale des femmes : le cas de l’Égypte
Authors: Alexandre-Leclair Laurice , Redien-Collot Renaud 
Published: June 2014

Mueller (2004) démontre que les intentions entrepreneuriales des femmes sont moindres que celles des hommes surtout dans les pays en voie de développement. Qu’en est-il dans un pays en économie de transition, comme l’Égypte ? Tout en relançant le questionnement de Mueller (2004), cette étude articule une comparaison sexuée et une approche genrée pour mieux comprendre le rôle des rapports hommes/femmes dans la formation de l’intention entrepreneuriale féminine dans une culture donnée. Grâce à une recherche quantitative menée en 2010 auprès de 320 étudiants égyptiens francophones au Caire, les auteurs ont pu démontrer que les étudiantes égyptiennes ont fortement le désir d’entreprendre et de concrétiser assez rapidement leurs projets, qu’elles sont assez confiantes dans leurs compétences à créer et conscientes des obstacles qu’elles rencontreront. La recherche révèle également certaines ambivalences des projets entrepreneuriaux des jeunes égyptiennes liées aux rapports de genre. Notre recherche complète ainsi les conclusions de Mueller (2004) et Langowitz et Minitti (2007). Nous pouvons arguer du fait que dans un pays en économie de transition le déséquilibre des motivations entrepreneuriales des femmes et des hommes est limité.
Rôle déterminant des ressources immatérielles dans la création de valeur dans une PME agroalimentaire de terroir1
Authors: Louzzani Yassine 
Published: June 2014

Cette étude vise à analyser le rôle des ressources immatérielles dans la création de valeur dans une entreprise installée dans une zone où le terroir peut être source d’avantages concurrentiels. À l’aide d’une étude de cas portant sur une PME agroalimentaire familiale du secteur fromager auvergnat, nous proposons une analyse en profondeur de ce rôle qui nous parait déterminant. Cette étude est de nature exploratoire et à visée compréhensive. Le mode de recueil des données est multi-angulé. L’hypothèse centrale dans cette recherche est que la création de valeur dans cette entreprise de terroir est déterminée par ses ressources immatérielles (humaines et celles liées au terroir) mobilisées.
Cette étude montre que les atouts essentiels de la PME étudiée sont de nature immatérielle ; tels que le label qu’elle partage avec le groupe stratégique de terroir, les savoir-faire distinctifs (maîtrise des risques sanitaires à travers l’application des normes, des ressources humaines qualifiées) et les relations privilégiées entretenues avec les différents partenaires (notamment les fournisseurs). D’où l’importance en termes de création de valeur des efforts d’investissements dans le capital immatériel (capital humain, image…) et de leur visibilité auprès de différents acteurs économiques et politiques (clients, fournisseurs, collectivités territoriales, interprofessions…). En effet, il nous semble nécessaire que les chercheurs en sciences de gestion participent à l’élaboration de cartographie(s) des ressources immatérielles dans les PME de terroir et plus généralement dans les entreprises industrielles.
