Authors: Bird Jonathan M. , Hall Jennifer , Arnold Rachel , Karageorghis Costas I. , Hussein Adil
Published: March 2016

The objective of the present study was to examine the effects of music and music-video on core affect during and immediately after stationary cycling at the lactate threshold. A randomized, fully counterbalanced, crossover design with three conditions (music, music-video, and a no-music-video control) was adopted. Twenty-four participants exercised at lactate threshold while exposed to music, music-video, and control conditions. Affective valence and perceived activation were assessed every 2 min during a 20-min exercise bout and every 5 min post exercise over a 20-min period. Results indicated that there was a significant condition x time interaction for affective valence. The music-video condition elicited the highest levels of affective valence followed by the music condition and control. There was a main effect of condition for affective valence, wherein the experimental conditions facilitated significantly higher affective valence than control. Significant main effects of time emerged for both affective valence and perceived activation. Regardless of condition, affective valence decreased during the exercise bout and increased immediately post exercise. Conversely, perceived activation increased during exercise and decreased immediately post exercise. The present findings indicate that music and music-video can enhance core affect during exercise at the lactate threshold and the implications for exercise adherence are expounded.

Published: March 2016

According to Bandura’s social cognitive theory, emotions constitute important sources of information for people to judge own efficacy to accomplish specific tasks. The present research employed a laboratory task to assess career starters’ anticipatory emotions and associations with chronic self-construal and emotion regulation strategies. The intensity of facial emotional expressions was assessed while participants were responding to scenarios regarding envisaged business start-up activities. Results from Bayesian path analysis found that independent self-construal was associated with lower intensity of facial expressions of fear; interdependence was associated with higher intensity of anger and disgust. Emotion suppression was associated with lower intensity of happiness and higher intensity of anger. Emotion reappraisal fully mediated relationships between independent self-construal and intensity of expressions of fear in women but not in men. Results add to an emerging literature that highlights the significance of emotions and cultural orientation in the entrepreneurial process.

Published: March 2016

Children’s physical activity has been correlated with child characteristics and social or physical environment. This study aimed to compare preschoolers’ physical activity among various sociodemographic characteristics and to determine barriers, motivators, and environmental factors for active play. A total of 835 preschoolers were included in this analysis. Time spent on active play, quiet play, and screen time was reported by parents. Boys spent significantly more time on active play and screen time than girls. Time spent on quiet play was highest in East Coast Peninsular Malaysia and lowest in Sarawak. Some 40% of children achieved active play recommendation while 27% exceeded daily screen time recommendation. Most parents reported that their child played actively in the house area; and that the main barrier and motivator to active play were safety and child’s enjoyment, respectively. These findings demonstrate that sociodemographic characteristics and environment should be considered in designing physical activity intervention programs.

Published: March 2016

Inflammatory bowel disease (IBD) is a common disorder of ferrets ( Mustela putorius furo) that may progress to lymphoma. Although routine histology is used to distinguish between these diseases, misclassifications may occur. Immunohistochemistry (IHC) is commonly used to distinguish between IBD and lymphoma in small animals. The objective of our study was to determine the agreement in the diagnosis reached solely using hematoxylin and eosin (HE)-stained, full-thickness sections versus using a combination of HE and IHC. Enteric sections from 44 ferrets previously diagnosed with IBD or intestinal lymphoma and 3 control ferrets were analyzed by pathologists with expertise in ferrets. A pathologist blinded to the original diagnosis assessed the same HE-stained sections. Analysis was then repeated using HE sections in parallel with sections stained using antibodies against CD3 and CD79a. No significant difference was found between the original HE diagnosis and the HE diagnosis reached by the blinded pathologist ( p = 0.91) or between the blinded pathologist’s HE versus HE with IHC diagnosis ( p = 0.16). In the 2 cases where disagreement was present, IHC was pivotal in reaching a final diagnosis. There was no significant age ( p = 0.29) difference between diagnoses; however, significantly more male ferrets were affected with IBD than females ( p = 0.004). Immunophenotype of the lymphoma was not correlated with predilection for location in the intestinal wall ( p = 0.44). Results suggest that although IHC is not necessary to distinguish IBD from intestinal lymphoma in ferrets, it can be useful a definitive diagnosis in cases of severe IBD.
Elderly Victimization and Fear of Crime in Public Spaces
Authors: Ceccato Vania , Bamzar Roya
Published: March 2016

Drawing upon environmental criminology principles and fear of crime literature, this article investigates the types of outdoor places where most crimes against the elderly happen as well as the types of places most feared by them. The study employs an analysis of secondary data, crime mapping, fieldwork, and interviews with residents in a senior housing area in Stockholm, Sweden. Results show that most crime victims were exposed to theft, and all incidents took place in the environment close to the senior housing. Elderly perceived safety follows a “distance decay” from the residence, the safest places being the areas immediately outside the entrance of the senior housing, while the least safe are the deserted areas close to the petrol station. Findings also show that for those who are fairly mobile, the fact that they avoid some places does not necessarily mean their mobility is restricted, as previously expected, but it makes them walk farther.
Minireview: Prognostic factors and the response to hydroxurea treatment in sickle cell disease
Authors: Wang Winfred C
Published: March 2016

This review describes current considerations in the use of hydroxyurea for the management of sickle cell disease in the context of clinical severity. Randomized trials of hydroxyurea have generally enrolled subjects with increased severity based on frequent vaso-occlusive events. An exception was the BABY HUG study in infants which documented substantial benefit even for asymptomatic subjects. Increasing data indicate that hydroxyurea has a substantial effect on reducing mortality in both adults and children—perhaps the most compelling reason for advocating the drug’s widespread use. Although the efficacy of hydroxyurea is mediated primarily through increased erythrocyte fetal hemoglobin and much has been learned about the genomic influences on fetal hemoglobin levels in sickle cell disease, our ability to predict the fetal hemoglobin response to hydroxyurea remains limited; much more work in this area is indicated. The review is concluded with the recommendations of the 2014 NIH Evidence-Based Management of Sickle Cell Disease Expert Panel Report.

Published: March 2016

Background. The positive correlation between therapeutic exercise and memory recovery in cases of ischemia has been extensively studied; however, long-term exercise begun after ischemic neuronal death as a chronic neurorestorative strategy has not yet been thoroughly examined. Objective. The purpose of this study is to investigate possible mechanisms by which exercise ameliorates ischemia-induced memory impairment in the aged gerbil hippocampus after transient cerebral ischemia. Methods. Treadmill exercise was begun 5 days after ischemia-reperfusion (I-R) and lasted for 1 or 4 weeks. The animals were sacrificed 31 days after the induction of ischemia. Changes in short-term memory, as well as the hippocampal expression of markers of cell proliferation, neuroblast differentiation, neurogenesis, myelin and microvessel repair, and growth factors were examined by immunohistochemistry and/or western blots. Results. Four weeks of exercise facilitated memory recovery despite neuronal damage in the stratum pyramidale (SP) of the hippocampal CA1 region and in the polymorphic layer (PoL) of the dentate gyrus (DG) after I-R. Long-term exercise enhanced cell proliferation and neuroblast differentiation in a time-dependent manner, and newly generated mature cells were found in the granule cell layer of the DG, but not in the SP of the CA1 region or in the PoL of the DG. In addition, long-term exercise ameliorated ischemia-induced damage of myelin and microvessels, which was correlated with increased BDNF expression in the CA1 region and the DG. Conclusions. These results suggest that long-term treadmill exercise after I-R can restore memory function through replacement of multiple damaged structures in the ischemic aged hippocampus.
When the media meet: Problems and promises of EU–China dialogue in the journalistic sphere
Authors: Pfeil Hélène
Published: March 2016

This paper argues that lack of interpersonal interaction between media professionals in Europe and China partly accounts for continued misperceptions and gaps in understanding between both the nations. Investing into people-to-people dialogue is essential for journalists to overcome prejudice and to improve mutual knowledge. Days during which journalists are immersed into another country’s culture and media scene have great potential to induce changes in perceptions, both at the individual and societal level. This can be attributed to the built-in multiplier effect of media publications reaching wide audiences. Drawing on the “Europe-China Media Exchange ” set up, developed by the Institute for Strategic Dialogue, the article presents achievements (but also lessons) learnt from interpersonal exchange programs developed for European and Chinese journalists.
A Unified Model of Depression
Authors: Beck Aaron T. , Bredemeier Keith
Published: March 2016

We propose that depression can be viewed as an adaptation to conserve energy after the perceived loss of an investment in a vital resource such as a relationship, group identity, or personal asset. Tendencies to process information negatively and experience strong biological reactions to stress (resulting from genes, trauma, or both) can lead to depressogenic beliefs about the self, world, and future. These tendencies are mediated by alterations in brain areas/networks involved in cognition and emotion regulation. Depressogenic beliefs predispose individuals to make cognitive appraisals that amplify perceptions of loss, typically in response to stressors that impact available resources. Clinical features of severe depression (e.g., anhedonia, anergia) result from these appraisals and biological reactions that they trigger (e.g., autonomic, immune, neurochemical). These symptoms were presumably adaptive in our evolutionary history, but are maladaptive in contemporary times. Thus, severe depression can be considered an anachronistic manifestation of an evolutionarily based “program.”
Alloantigen presentation and graft-versus-host disease: fuel for the fire
Authors: Koyama Motoko , Hill Geoffrey R.
Published: March 2016

Allogeneic stem cell transplantation (SCT) is a unique procedure, primarily in patients with hematopoietic malignancies, involving chemoradiotherapy followed by the introduction of donor hematopoietic and immune cells into an inflamed and lymphopenic environment. Interruption of the process by which recipient alloantigen is presented to donor T cells to generate graft-versus-host disease (GVHD) represents an attractive therapeutic strategy to prevent morbidity and mortality after SCT and has been increasingly studied in the last 15 years. However, the immune activation resulting in GVHD has no physiological equivalent in nature; alloantigen is ubiquitous, persists indefinitely, and can be presented by multiple cell types at numerous sites, often on incompatible major histocompatibility complex, and occurs in the context of intense inflammation early after SCT. The recognition that alloantigen presentation is also critical to the development of immunological tolerance via both deletional and regulatory mechanisms further adds to this complexity. Finally, GVHD itself appears capable of inhibiting the presentation of microbiological antigens by donor dendritic cells late after SCT that is mandatory for the establishment of effective pathogen-specific immunity. Here, we review our current understanding of alloantigen, its presentation by various antigen-presenting cells, subsequent recognition by donor T cells, and the potential of therapeutic strategies interrupting this disease-initiating process to modify transplant outcome.

This interview with literary critic Jonathan Arac was conducted at the University of Pittsburgh on May 19, 2015. Arac, a member of the boundary 2 editorial collective since 1979, speaks at length about his life and work. Addressing the impact of theory on his career, he discusses how he came to be associated with the New Americanists, his project of a new literary history, the changes in his own writing, and his involvement with the journal boundary 2. Arac also reflects on his teaching and his directorship of the Humanities Center at the University of Pittsburgh. The interview concludes with a conversation about the 1930s and the period's continuing relevance for the twenty-first century, Arac's recent project on the “Age of the Novel,” and the transformations in the field since he first began teaching.
The Sublime without Longinus
Authors: Porter James I.
Published: March 2016

The contemporary understanding of Longinus and the sublime, which has been dominant for centuries (since Boileau), is crucially flawed. It is Longino-centric, it is riddled with assumptions about rhetoric, philosophy, and nature, and it forcibly enrolls the sublime in a well-worn tale about the aesthetic origins of modernity, which must itself transcend antiquity in order to be fully modern. On a fresh look at the problem, Longinus can be shown to be an incidental moment in the history and reception of the sublime. Far from being a principle of rhetorical criticism that emerged late in the day, the sublime proves to be an essential way of comprehending Greek and Roman thought and experience at their most exuberant and searching moments, from their earliest beginnings to their final appearances.
Epidermal growth factor suppresses intestinal epithelial cell shedding via a MAPK dependent pathway.

Published: March 2016

Cell shedding from the intestinal villus is a key element of tissue turnover, essential to maintain health and homeostasis. However, the signals regulating this process are not well understood. We asked whether shedding is controlled by epidermal growth factor receptor (EGFR), an important driver of intestinal growth and differentiation. In 3D ileal enteroid culture and cell culture models (MDCK, IEC-6, IPEC-J2 cells), extrusion events were suppressed by EGF, as determined by direct counting of released cells or rhodamine-phalloidin labeling of condensed actin rings. Blockade of MEK/ERK, but not other downstream pathways such as PI3K or PKC, reversed EGF inhibition of shedding. These effects were not due to a change in cell viability. Furthermore, EGF-driven MAPK signaling inhibited both caspase-independent and -dependent shedding pathways. Similar results were found in vivo, in a novel zebrafish model for intestinal epithelial shedding. Together, the data show that EGF suppresses cell shedding in the intestinal epithelium through a selective, MAPK dependent pathway affecting multiple extrusion mechanisms. EGFR signaling may be a therapeutic target for disorders featuring excessive cell turnover, such as inflammatory bowel diseases.
The magnetic orientation of the Antarctic amphipod Gondogeneia antarctica is cancelled by very weak radiofrequency fields
Authors: Tomanova K. , Vacha M.
Published: March 2016

Studies on weak man-made radiofrequency electromagnetic fields (RF) affecting animal magnetoreception aim for a better understanding of the reception mechanism and also point to a new phenomenon having possible consequences in ecology and environmental protection. RF impacts on magnetic compasses have recently been demonstrated on migratory birds and other vertebrates. We set out to investigate the effect of RF on the magnetic orientation of the Antarctic krill species Gondogeneia antarctica, a small marine crustacean widespread along the Antarctic littoral line. Here, we show that having been released under laboratory conditions, G. antarctica escaped in the magnetically seaward direction along the magnetic sea-land axis (Y-axis) of the home beach. However, the animals were disoriented after being exposed to RF. Orientation was lost not only in an RF of a magnetic flux density of 20 nT, as expected according to the literary data, but even under the 2 nT originally intended as a control. Our results extend recent findings of the extraordinary sensitivity of animal magnetoreception to weak RF fields in marine invertebrates.
Roof Skeletons and Graph Theory Trees
Authors: Козневски  , Kozniewski E.
Published: March 2016

The problem of constructing roofs of many papers [1;

6; 7; 9; etc.]. In this case, some studies suggested to use a computer

and special programs [10; 13; 16; etc.]. The geometry of the

efficient design of roofs is actual scientific direction, so in the

educational process of architectural and building trades made corresponding

innovations [2; 8; 14; 15; 17–20; etc.].

The roofs considered in this article are defined as special geometric

polyhedral surfaces, on the basis of two assumptions: (1) all

eaves of a roof form a planar (simply-connected or k-connected)

polygon called the base, (2) every hipped roof end makes the same

slope angle with the (horizontal) plane which contains the base.

All the vertices and edges of such a roof, forming the roof skeleton,

determine a graph. The orthogonal projection of a roof skeleton

onto the base plane leads to a planar graph. On the basis of [11] and [12] and continuing the investigations

for regular roofs, we formulate further properties which enable studying

the shapes of the roofs spread over simply connected v-gons for

an arbitrary integer v (v ≥ 3). We also introduce new operations:

splitting and grafting of graphs, and formulate some properties of

these operations. By means of such operations, the creation of a

graph with cycles using two or more trees is possible. In particular,

the operation of the grafting of a roof allows modeling an atrial roof.
Formation of the Surfaces of Side Slopes of Embankments and Excavations
Authors: Сальков  , Sal'kov Nikolay
Published: March 2016

Designing of surfaces attracted many experts in the

field of applied geometry. However, there was paid quite little attention

to the formation of the surfaces of side slopes of embankments

and excavations, probably due to the belief that there was

done possible and there is nothing more to consider. The problem

was that the question of the side slopes from put or taken out ground

coat was discussed in the all textbooks for the builders while occupying

a very small number of pages and the tasks in these textbooks

were on the one hand simple, on the other – completed. Unfortunately,

these tasks’ solutions have one and the same defect: the lack of a

systematic approach to the study of the slopes’ formation, and

therefore this unfortunate mistake at the corners of building areas, which could not (and unfortunately) can´t see the developers of

modern textbooks for builders and architects. This work is characterized

by the presence of the system approach, which eliminates

any mistakes in training and in operation of excavation.

In this work the author gives the information on the building

of slopes with filled soil for ground work. All the necessary for correct

image in the drawing examples are given. As follows from the

analysis the image of slopes of embankments in projections with

numerical marks is identical to the image of excavations, only with

a different sign of a numeric mark. Special attention was paid to

the construction of embankments’ slopes and excavations on the

corners of buildings, because all the modern textbooks contain

annoying mistakes.

Published: March 2016

The article is devoted to the Open All-Russian Student Olympiad on descriptive geometry, engineering and computer graphics in 2015. In accordance with the provision during the Open All-Russian Student Olympiad operated three sections: «Descriptive Geometry» (DG), «Engineering Graphics» (EG), «Computer Graphics» (CG). University team may consist of five students, the result of the team in each section is defined as the sum of the four best results. The final outcome of the university team´s performance is defined as the sum of the results in all three sections of DG, EG and CG. The criterion of success of the Open All-Russian Student Olympiad — Σ is the sum of the four parameters: Σ = p + k/10 + n + m, where p — number of universities participating of Open All-Russian Student Olympiad; k — number of students — participants of the Olympiad; n — number of subjects of the Russian Federation submitted to the competition; m — number of federal districts represented at the Olympiad. Criterion Indicator Σ2015 is the highest — the Olympiad 2015 is the most successful of the past fourteen. In the Open All-Russian Student Olympiad 2015 took part 24 unversities, 19 in Moscow and 5 in Novosibirsk. The vast majority of universities — 20 (83%), was able to prepare a full team of 4...5 people for participation in the Open All-Russian Student Olympiad 2015. Most of the participating universities (15) were able to speak in three sections. Five teams were in two sections and four in one. Students of the teams who performed in one section, prepared by a one-sided, and therefore, there is a major risk, that the training at the departments of these universities one-sided, that is not permissible. The analysis of performed Olympiad tasks leads to the conclusion, that the section «Descriptive Geometry» is the most intellectually capacious competitions in graphic disciplines. Participating teams from St. Petersburg has changed the balance of power at the National Student Olympiad on descriptive geometry, engineering and computer graphics, they pressed the dominate Institute of Fine Chemical Technologies named after M.V. Lomonosov and Tyumen State Oil and Gas University. Institute of Fine Chemical Technologies named after M.V. Lomonosov and Tyumen State Oil and Gas University lead in the ranking, according to the amount of places in the last four years: Institute of Fine Chemical Technologies named after M.V. Lomonosov is number one, Tyumen State Oil and Gas University is second best.
When Is Information Sufficient for Action? Search with Unreliable yet Informative Intelligence
Authors: Atkinson Michael , Kress Moshe , Lange Rutger-Jan
Published: March 2016

We analyze a variant of the whereabouts search problem, in which a searcher looks for a target hiding in one of n possible locations. Unlike in the classic version, our searcher does not pursue the target by actively moving from one location to the next. Instead, the searcher receives a stream of intelligence about the location of the target. At any time, the searcher can engage the location he thinks contains the target or wait for more intelligence. The searcher incurs costs when he engages the wrong location, based on insufficient intelligence, or waits too long in the hopes of gaining better situational awareness, which allows the target to either execute his plot or disappear. We formulate the searcher’s decision as an optimal stopping problem and establish conditions for optimally executing this search-and-interdict mission.

Published: March 2016

Androgen receptor (AR) and prostate-specific antigen (PSA) are expressed in the prostate and are involved in prostate cancer (PCa). The aim of this study was to develop reliable protocols for reproducible quantification of AR and PSA in benign and malignant prostate tissue using time-resolved fluorescence (TRF) imaging techniques. AR and PSA were detected with TRF in tissue microarrays from 91 PCa patients. p63/ alpha-methylacyl-CoA racemase (AMACR) staining on consecutive sections was used to categorize tissue areas as benign or cancerous. Automated image analysis was used to quantify staining intensity. AR intensity was significantly higher in AMACR+ and lower in AMACR- cancer areas as compared with benign epithelium. The PSA intensity was significantly lower in cancer areas, particularly in AMACR- glands. The AR/PSA ratio varied significantly in the AMACR+ tumor cells as compared with benign glands. There was a trend of more rapid disease progression in patients with higher AR/PSA ratios in the AMACR- areas. This study demonstrates the feasibility of developing reproducible protocols for TRF imaging and automated image analysis to study the expression of AR and PSA in benign and malignant prostate. It also highlighted the differences in AR and PSA protein expression within AMACR- and AMACR+ cancer regions.
Geschlechterdiskurse um 1900
Authors: Bauer Jenny
Published: March 2016

Die frühe Moderne gilt als eine Epoche sich dynamisierender Geschlechterbeziehungen. Skandinavien nimmt in dieser Hinsicht eine Vorbildfunktion für den deutschsprachigen Diskurs ein. Anhand von Romanen von Thomas Mann, Gabriele Reuter, Herman Bang und Toni Schwabe zeigt Jenny Bauer, dass die Diversität literarischer Identitätsentwürfe eng an die Produktion sozialer, nationaler und imaginärer Räume gebunden ist. Diese verschiedenen Dimensionen des Raumes bilden das Kernstück von Henri Lefebvres Theorie, die hier erstmals zur Analyse literarischer Texte eingesetzt wird. In diesem Zusammenhang werden Korrelationen zwischen Lefebvres prozesshaftem Raumdenken und aktuellen Gender-Theorien sichtbar.

Was interessiert Frauen (nicht) an Technikmuseen? Anna Döpfner untersucht die mangelnde Repräsentation von Frauen in Technikmuseen, deren Ursachen und neue Ansatzpunkte zum gendergerechten Forschen, Sammeln und Ausstellen. Ihre Studie, die zentrale museologische Fragestellungen mit der langjährigen Innensicht der Verfasserin auf das Technikmuseum in Berlin verknüpft, regt an zu multiperspektivischem Denken - etwa zwischen den Polen von Technik und Arbeit oder Werkzeug- und Sozialentwicklung. Das Buch regt über den fachlichen Rahmen hinaus dazu an, Ausstellungen genauer zu betrachten und daraufhin zu befragen, wer dort zu wem spricht und damit welche Wirkung hervorruft.
Autopoiesis und Literatur
Authors: Schmid Marcel
Published: March 2016

Literarische Texte treffen nicht einfach Aussagen, etwa über psychische oder politische Sachverhalte, sondern thematisieren stets auch ihre eigene Verfasstheit. Diesem Topos literaturwissenschaftlicher Forschung verschafft Marcel Schmid mit dem kognitionsbiologischen Begriff »Autopoiesis« eine neue Akzentuierung. »Autopoiesis«, so die These, eignet sich einerseits als Analysebegriff zur Beschreibung von selbstbezüglichen Textverfahren, die beispielsweise bei Kleist und Kafka erkennbar sind. Andererseits ist »Autopoiesis« die eigene Historizität eingeschrieben - als ein Konzept, das die Kognitionsbiologie mit Systemtheorie und Literaturwissenschaft verbindet.

Die Geschichte der in Deutschland stationierten, afroamerikanischen Soldaten ist bislang wenig beachtet worden. Maria Höhn und Martin Klimke zeichnen nach, wie sich das Land im Laufe des 20. Jahrhunderts als wichtiger Bezugspunkt im afroamerikanischen Kampf um die Gleichberechtigung und zur Beendigung der Segregation in den USA herausbildete. Von den beiden Weltkriegen und der Besatzungszeit bis in die späten 1970er Jahre schildern sie die Proteste in den US-Militärbasen und Garnisonsstädten in der Bundesrepublik, den Besuch von Dr. Martin Luther King Jr. in Berlin 1964, die Allianz der Studentenbewegung mit der Black-Power- und GI-Bewegung sowie die Angela-Davis-Solidaritätskampagnen in Ost- und Westdeutschland.
Programas de intervenção para o desenvolvimento de competências socioemocionais: Uma revisão crítica dos enquadramentos SEL e SEAL
Authors: Coelho Vítor Alexandre , Marchante Marta , Sousa Vanda , Romão Ana Maria
Published: March 2016

Nos últimos anos tem aumento o interesse nos programas de desenvolvimento de competências socioemocional baseadas em escolas, face à perceção incrementadas destas como cruciais para o sucesso na vida e na escola. Este aumento impulsionou a criação de medidas legislativas de suporte e orientação nos Estados Unidos (Social and Emotional Learning - SEL) e em Inglaterra (Social and Emotional Aspects of Learning - SEAL). O presente artigo pretende analisar as semelhanças e as diferenças entre as duas abordagens, comparando vários pontos cruciais como objetivos, âmbito de intervenção, estratégia de implementação, formatos dos programas, implementadores empregues e a adequação da implementação dos programas com o respetivo enquadramento teórico. Adicionalmente será analisada a eficácia e a efetividade de cada abordagem, contemplando questões como a existências de diferenças de género no impacto de programas de desenvolvimento socioemocional, bem como a importância de envolver múltiplos informantes na avaliaçao dos resultados. Em suma, pretendeu-se analisar criticamente estas abordagens de forma a apoiar a implementação de programas eficazes em Portugal, bem como identificar as temáticas que requerem investigação adicional. Pode-se concluir que são necessários estudos adicionais sobre a efetividade, o formato mais adequado e o impacto do género sobre os programas de desenvolvimento socioemocional.

We obtain that there is no stable complete noncompact 1-minimal hypersurface in S4 with nonzero Gauss-Kronecker curvature and _nite total curvature. We show that there is no stable complete noncompact 1-minimal hypersurface in S4 with polynomial volume growth, nonzero Gauss-Kronecker curvature and supM H2 < 5/2. At last, we discuss stable complete noncompact hypersurfaces M with constant scalar curvature R > 1 in Sn+1 and show another nonexistence result. These results are generalised versions of results of Alencar, Santos, Zhou and Silva Neto on stable hypersurfaces in Rn+1 with constant scalar curvature.

Fetuin-A is a negative acute phase reactant, while procalcitonin is an indicator of severe bacterial infection. Diagnosis of bacterial infection in febrile seizure (FS) is important for choosing the most suitable treatment. In this study, serum fetuin-A was estimated, for the first time, in the inpatients with FS and compared with procalcitonin and blood culture tests.

A total of 60 children (28 male and 32 female) with FS in addition to 30 sex- and age-matched children participated in the study. Patients were classified according to sex, age, PCT level (high PCT>0.5ng/mL), C-reactive protein (CRP, positive >6mg/L), and according to the results of the blood culture.

Fetuin-A level decreased and PCT level increased in FS patients in comparison to those in the control group. These changes are significantly increased (p<0.05) in the positive CRP group compared with that of the negative CRP group. Kernel density estimation showed that procalcitonin is a better indicator of the infection in FS children than fetuin-A . Procalcitonin is more sensitive and specific than fetuin-A and when used together they produce 100% sensitivity and specificity for the diagnosis of bacterial infection in FS patients.

Fetuin-A is low in FS patients and can be used with procalcitonin in the diagnosis of bacterial infection in FS.
Aortic Dissection - The Role of Echocardiography in Emergency Unit: Case Report
Authors: Stojanović Sanja , Ilić Marina Deljanin , Ilić Stevan , Ilić Bojan , Stojanović Milovan , Petrović Dejan
Published: March 2016

Aortic dissection is a quite rare but serious condition, often associated with a very high mortality rate; it is manifested by sudden chest pain and acute hemodynamic compromise. In the presented review, a case of an ascending aortic dissection with the lethal outcome is been shown. A healthy man with no past history of illness suddenly felt acute excruciating chest pain which was radiating to the back. A quick diagnosis, ideally within one hour of manifestation, heart auscultation and echocardiography are the key to aortic dissection recovery.

Authors: Klamka J. , Babiarz A. , Niezabitowski M.
Published: March 2016

The main aim of this article is to review the existing state of art concerning the complete controllability of semilinear dynamical systems. The study focus on obtaining the sufficient conditions for the complete controllability for various systems using the Banach fixedpoint theorem. We describe the results for stochastic semilinear functional integro-differential system, stochastic partial differential equations with finite delays, semilinear functional equations, a stochastic semilinear system, a impulsive stochastic integro-differential system, semilinear stochastic impulsive systems, an impulsive neutral functional evolution integro-differential system and a nonlinear stochastic neutral impulsive system. Finally, two examples are presented.
Optimum allocation of active power filters in large supply systems
Authors: Maciążek M. , Pasko M.
Published: March 2016

Problems concerning electrical power quality and especially estimation of costs required for reduction of higher harmonics in power network voltage and current time waveforms have been considered in the paper. The application of active power filters to reduction of higher harmonics has been analysed taking into account, in particular, the necessary investment costs. Two goal functions have been used to solve the underlying optimization problem - the first one that enables direct cost minimization and the second one based on the cost-effectiveness approach used by economists. Such approach is substantially different from solutions proposed by other authors who concentrate rather on theoretical issues and do not take into consideration the economical market-based reality. In the paper, theoretical analysis has been followed by an example of optimal allocation of active power filters in a large supply system.
Repetitive neurocontroller with disturbance feedforward path active in the pass-to-pass direction for a VSI inverter with an output LC filter
Authors: Ufnalski B. , Grzesiak L.M.
Published: March 2016

An enhancement to the previously developed repetitive neurocontroller (RNC) is discussed and investigated in the paper. Originally, the time-base generator (TBG) has been used to produce the only input signal for the neural approximator. The resulting search space makes the dynamic optimization problem (DOP) of shaping the control signal solvable with the help of a function approximator such as the feed-forward neural network (FFNN). The plant under consideration, i.e. a constant-amplitude constant-frequency voltage-source inverter (CACF VSI) with an output LC filter, is assumed to be equipped with the disturbance load current sensor to enable implementation of the disturbance feed-forward (pDFF) path as a part of the non-repetitive subsystem acting in the along the pass p-direction. An investigation has been undertaken to explore potential benefits of using this signal also as an additional input for the RNC to augment the approximation space and potentially enhance the convergence rate of the real-time search process. It is numerically demonstrated in the paper that the disturbance feed-forward path active in the pass-to-pass k-direction (kDFF) improves the dynamics of the repetitive part as well indeed.
Green’s function approach to frequency analysis of thin circular plates
Authors: Żur K.K.
Published: March 2016

The free vibration analysis of homogeneous and isotropic circular thin plates by using the Green’s functions is considered. The formulae for construction of the influence function for all nodal diameters are presented in a closed form. The limited independent solutions of differential Euler equations were expanded in the Neumann power series using the method of successive approximation. This approach allows to obtain the analytical frequency equations as power series rapidly convergent to exact eigenvalues for different number of nodal diameters. The first ten dimensionless frequencies for eight different natural modes of circular plates are calculated. A part of obtained results have not been presented yet in open literature for thin circular plates. The results of investigation are in good agreement with selected results obtained by other methods presented in literature.
De l’endurance à la résilience : les romans de Felicia Mihali
Authors: Ionescu Mariana
Published: March 2016

Female characters occupy a special place in Felicia Mihali’s novels. Victims of both Man and History, they show a remarkable endurance in the face of life’s difficulties. Special attention will be paid to the novels Le Pays du fromage [The Land of Cheese] and Confession pour un ordinateur [Confession to a Computer] whose narrators (re)construct their identity from fragmented memories, readings, and reveries. With the help of Boris Cyrulnik’ observations, this article will show how these enduring women’s resilience is “knitted” concurrently with that of their people, a people tried by many social and historic disruptions.
Représentation du refoulement de l’inceste : l’(anti)Œdipe dans l’œuvre d’Agota Kristof
Authors: Desorbay Bernadette
Published: March 2016

Several haunting themes inhabit the border writing of Agota Kristof including incest between brother and (half)sister and schizoid twinhood. Whereas fusion and duplication treats her in-between position between East and West as well as between a younger brother whom the mother considered as her favourite and an elder brother whom she herself passionately loved, the issue of a deuleuzian decontextualization and the representation of the suppression of incest motivating her writing range from a rejection to an approach of the Oedipus complex. The urge to write has finally faded away leaving a last uncompleted and unpublished novel, about which she speaks in her interviews and whose destiny could be related to a painful focalisation on a personal myth linked to a friend and surrogate father. Kristof died in 2011. She was 75 years old.
Reaching an entrepreneurial management system of amoebas. A qualitative insight into the European experiences
Authors: Urban Wiesław , Czerska Joanna
Published: March 2016

The aim of the study is an assessment of the Amoeba Management System (AMS) introduction advancements in some European companies. The study takes the practically focused research approach. The approaches, achievements and phases whilst introducing the AMS principles by companies are observed and critically assessed. First insight into the challenges of AMS introduction is taken basing on critical study of the literature output. The scientific studies and managerial publications are taken into consideration. The empirical part of the study is based on the qualitative approach. A multiple case study methodology is employed. The research objects are three companies, one of them operates in Sweden, the next two in Poland. Each of them have different experiences in AMS implementation, they also manifest different management styles and habits. The study demonstrates that AMS is a very prospective management methodology which can support companies in employees commitment during their journey towards operational excellence. The analysis results show different motivations for AMS introduction as well as different development paths, these are harmonized with different management styles in companies and culture occurring in countries. The study is particularly valuable because this is one of the first empirical investigations of AMS implementation in European companies. In the field of theory the study proposes the four level scale for amoebas system maturity. This scale allows to classify companies following AMS principles and, at the same time, this scale is also the kind of path of AMS implementation. The study points out basic tools for companies which support AMS implementation. These tools are already known in management literature, but experience of investigated companies shows that they are fundamental for successful AMS implementation.
