Identitätsmanagement beim ‚Sharing' in Social Network Services

Offentliche Kommunikationsprozesse im Internet werden zunehmend von einer Praxis des ‚Sharing’ von Medieninhalten in Social Network Services (SNS) gepragt. Diese lasst sich aus der Perspektive der NutzerInnen, die sich unter anderem mit dem ‚Teilen’ von Blogposts, Zeitungsartikeln oder YouTube-Videos ihren jeweiligen Kontakten gegenuber darstellen, als Identitatsmanagement beschreiben. Auf Basis einer Analyse von 41 schwach strukturierten Interviews mit NutzerInnen zeigen die Autoren, wie facettenreich die Verbindungen zwischen Identitat und geteilten Medieninhalten durch die NutzerInnen konstruiert werden, wie die NutzerInnen ihre Nachrichten an unterschiedlich antizipierte Publika anpassen und wie sie dabei mit der Auflosung der traditionellen sozialer Kontexte innerhalb von SNS umgehen. Die Autoren liefern einen Beitrag zum Verstandnis der Motive und Kontexte individueller Handlungen, auf denen die Dynamiken der Entwicklung von Netzoffentlichkeiten auf MakroEbene basieren. 1. Einleitung Die Praxis, Blogposts, Zeitungsartikel, YouTube-Videos und andere online verfugbare Medieninhalte uber Social Network Services (SNS) zu ‚teilen’ ist weit verbreitet (BITCOM 2011, Hermida et al. 2011, Purcell et al. 2010). Unter ‚teilen’ oder ‚sharen’ meinen wir, wenn ein Link zu einem Medieninhalt in eine ‚Statusmeldung’ auf Facebook, in einen Tweet auf Twitter oder in andere SNS eingefugt wird. Fur die Kontakte der ‚teilenden’ NutzerInnen erscheinen Nachrichten und Links innerhalb ihres Social Streams oder News Feeds, einer laufend aktualisierten und ruckwarts chronologisch geordneten Liste der Nachrichten all jener Akteure, mit denen sie uber das System in Verbindung stehen. Indem SNS-NutzerInnen Medieninhalte teilen, werden diese verbreitet. Gleichzeitig geben sie Anstos zur Auseinandersetzung mit den Themen, auf die sich die verlinkten Inhalte beziehen, da auf jede Nachricht mit einer Palette von Interaktionsoptionen reagiert werden kann. Uber Kommentare und Weiterleitungen (‚Retweets’, ‚Reshares’) wird die Bedeutung der Medieninhalte ausgehandelt. Die Beteiligung an diesen Aushandlungsprozessen (oder auch nur ihrer Beobachtung) pragt die individuelle Bedeutungskonstruktion zu den jeweiligen Themen fur die NutzerInnen mit. Hierin zeigen sich durchaus Ahnlichkeiten zu
PI3K class II α regulates δ-opioid receptor export from the trans-Golgi network

The δ-opioid receptor (δR) is retained in intracellular structures in neurons, but the mechanisms of retention and regulated export are not known. The atypical phosphoinositide-3 kinase C2A is required and sufficient for NGF-regulated δR export from the trans-Golgi network and surface transport.
A Novel Link Between Adipokines And Lipoprotein (A) To Contemplate Their Diagnostic Role In Patients With Stemi And Nstemi.

BACKGROUND Early detection of cardiac events allow better and cost-effective triage and welltimed management of these patients. Study was conducted to evaluate the prognostic significance of plasma adiponectin, resistin and lipoprotein (a) in a group of patients with ST segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction. These parameters were also compared with other predictors like troponin T, troponin I and CK-MB. METHODS Present study was based on the 100 patients with AMI of whom 52 had a diagnosis of STEMI, and 48 had NSTEMI. Duration of study was January to June 2015. Patients having chest pain that was indicative of myocardial ischemia within first 12 hours after the onset of symptoms were included in the study. Adiponectin, Lp (a), resistin, troponin T and troponin I were estimated using ELISA method. Level of CK-MB was measured by Auto-analyser using standard kit of Merck. RESULTS Mean age of patients with STEMI was 52.32 years and with NSTEMI it was 48.17 years. Mean value of BMI of patients with STEMI was 28.33 and with NSTEMI was 25.22 Kg/m2. Duration of chest pain in patients with STEMI was 8.64 and patients with NSTEMI it was 16.52hours with highly significant difference (p<0.001). History of smoking in patients with STEMI was more as compared to the patients with NSTEMI. Level of CPK, adiponectin and lipoprotein (a) was raised in patients with STEMI as compared to patients with NSTEMI but significant difference was only found in levels of CPK (p<0.001) and in adiponectin (p<0.05). Level of serum CK-MB, TnT, TnI and resistin was raised in patients with NSTEMI as compared to patients with STEMI but significant difference (p<0.001) was only observed in serum troponin I concentration. CONCLUSIONS It is concluded that the incidence of STEMI and NSTEMI is similar in our patients. However, the markers of STEMI are increased level of adiponectin and Lp(a) and the markers of NSTEMI are troponins especially troponin I, resistin and CKMB.
The birth and evolution of surface science: Child of the union of science and technology

This article is an account of the birth and evolution of surface science as an interdisciplinary research area. Surface science emanated from the confluence of concepts and tools in physics and chemistry with technological innovations that made it possible to determine the structure and properties of surfaces and interfaces and the dynamics of chemical reactions at surfaces. The combination in the 1960s and 1970s of ultra-high-vacuum (i.e., P < 10−7 Pascal or 10−9 Torr) technology with the recognition that electrons in the energy range from 50 to 500 eV exhibited inelastic collision mean free paths of the order of a few angstroms fostered an explosion of activity. The results were a reformulation of the theory of electron solid scattering, the nearly universal use of electron spectroscopies for surface characterization, the rise of surface science as an independent interdisciplinary research area, and the emergence of the American Vacuum Society (AVS) as a major international scientific society. The rise of microelectronics in the 1970s and 1980s resulted in huge increases in computational power. These increases enabled more complex experiments and the utilization of density functional theory for the quantitative prediction of surface structure and dynamics. Development of scanning-probe microscopies in the 1990s led to atomic-resolution images of macroscopic surfaces and interfaces as well as videos of atoms moving about on surfaces during growth and diffusion. Scanning probes have since brought solid–liquid interfaces into the realm of atomic-level surface science, expanding its scope to more complex systems, including fragile biological materials and processes.
Macrophages Are the Determinant of Resistance to and Outcome of Nonlethal Babesia microti Infection in Mice

ABSTRACT In the present study, we examined the contributions of macrophages to the outcome of infection with Babesia microti, the etiological agent of human and rodent babesiosis, in BALB/c mice. Mice were treated with clodronate liposome at different times during the course of B. microti infection in order to deplete the macrophages. Notably, a depletion of host macrophages at the early and acute phases of infection caused a significant elevation of parasitemia associated with remarkable mortality in the mice. The depletion of macrophages at the resolving and latent phases of infection resulted in an immediate and temporal exacerbation of parasitemia coupled with mortality in mice. Reconstituting clodronate liposome-treated mice at the acute phase of infection with macrophages from naive mice resulted in a slight reduction in parasitemia with improved survival compared to that of mice that received the drug alone. These results indicate that macrophages play a crucial role in the control of and resistance to B. microti infection in mice. Moreover, analyses of host immune responses revealed that macrophage-depleted mice diminished their production of Th1 cell cytokines, including gamma interferon (IFN-γ) and tumor necrosis factor alpha (TNF-α). Furthermore, depletion of macrophages at different times exaggerated the pathogenesis of the infection in deficient IFN-γ−/− and severe combined immunodeficiency (SCID) mice. Collectively, our data provide important clues about the role of macrophages in the resistance and control of B. microti and imply that the severity of the infection in immunocompromised patients might be due to impairment of macrophage function.
Laryngealization and Breathiness in Persian

Persian has sequences of two vowels separated by an intervening glottal consonant (/ h / or /  /). The VG(lottal)V sequence becomes reduced in certain occurrences, with the perceptual effect of the loss of the glottal consonant. The purpose of this study is to provide an acoustic description of VGV sequences in reduced forms. A production study examined three acoustic measurements of phonation types: H1-H2, H1-F1, and F0. The measurements were made at 15 ms time intervals throughout the second vowel to determine the time course of phonation effect. The issue of interest is what properties of VGV remain where G is lost. It is shown that /  / will be preserved as vowel laryngealization and / h /
Theoretical Analysis of Mechano-to-Neural Transduction in Pacinian Corpuscle

This paper presents a critical review of the most relevant experimental data obtained from electrophysiological studies of the Pacinian corpuscles. A mathematical model of the mechanoreceptor is proposed and utilized to clarify the relationships between the variables involved in the mechano-to-neural transduction. This model accounts for the two main components of the corpuscle: the lamellated structure and the peripheral segment of the afferent axon.
Human Blood-Brain Barrier Disruption by Retroviral-Infected Lymphocytes: Role of Myosin Light Chain Kinase in Endothelial Tight-Junction Disorganization1

The blood-brain barrier (BBB), which constitutes the interface between blood and cerebral parenchyma, has been shown to be disrupted during retroviral associated neuromyelopathies. Human T cell leukemia virus (HTLV-1)-associated myelopathy/tropical spastic paraparesis is a slowly progressive neurodegenerative disease, in which evidence of BBB breakdown has been demonstrated by the presence of lymphocytic infiltrates in the CNS and plasma protein leakage through cerebral endothelium. Using an in vitro human BBB model, we investigated the cellular and molecular mechanisms involved in endothelial changes induced by HTLV-1-infected lymphocytes. We demonstrate that coculture with infected lymphocytes induces an increase in paracellular endothelial permeability and transcellular migration, via IL-1α and TNF-α secretion. This disruption is associated with tight junction disorganization between endothelial cells, and alterations in the expression pattern of tight junction proteins such as zonula occludens 1. These changes could be prevented by inhibition of the NF-κB pathway or of myosin light chain kinase activity. Such disorganization was confirmed in histological sections of spinal cord from an HTLV-1-associated myelopathy/tropical spastic paraparesis patient. Based on this BBB model, the present data indicate that HTLV-1-infected lymphocytes can induce BBB breakdown and may be responsible for the CNS infiltration that occurs in the early steps of retroviral-associated neuromyelopathies.
Changes in Antisocial Behaviour in the Classroom and the Impact on Students, in Spain

The aim of this study is to know teachers’ opinions on antisocial behaviour in the classroom and its effect on pupils. Our sample was made up of 493 secondary and primary school teachers in the Valencia Community (Spain), and the research instrument was a questionnaire elaborated by the Values, Violence and Education Interdisciplinary Research Group of the University of Alicante. The data was put on the group’s online platform, and analysed using the programme SPSS v.21. The different types of antisocial behaviour highlighted by teachers were social exclusion, physical aggression and addictions, and also, but with less frequency, vandalism, insults and xenophobia. Emotional problems and a bad learning environment are the main consequences of these behaviours. Our study comes to the conclusion that there is a direct relationship between different types of school violence and pupils’ negative behaviour. Thus, programmes of prevention must be developed with the aim of reducing risk factors, solving conflicts and educating pupils in specific social skills.

Système d'aide à la reformulation de requêtes réparties sur les sources d'information hétérogènes

A la suite de l'evolution rapide des reseaux de communication, de l'avenement de l'Internet et de la mise en ligne de bases de donnees sur la toile, un gigantesque espace d'information heterogene est devenu accessible a tous et son volume augmente considerablement chaque annee. Actuellement, nous pouvons acceder plus ou moins efficacement a l'information via les bases de donnees, les systemes de recherche d'informations ou les systemes de decouverte de connaissances. Face a ce flot d'informations, des outils d'interrogation specifiques, le plus souvent booleens, permettent theoriquement aux utilisateurs de rechercher et de trouver l'information souhaitee. Cependant, pour l'utilisateur, la tâche d'interrogation reste particulierement difficile car celui-ci n'a pas toujours recours aux termes necessaires qui lui permettraient d'exprimer ses besoins en information de facon pertinente. Les reponses s'averent donc peu satisfaisantes, car trop nombreuses, bruitees (restitution de documents non pertinents), peu precises et bien souvent incompletes. Pour ameliorer les performances de la recherche, nous proposons un systeme d'interrogation qui doit permettre une utilisation plus aisee et surtout plus efficace des differentes sources d'informations actuellement disponibles (bases locales, CD/ROM, serveurs classiques et Internet : web, news, wais). Ce systeme est base sur la reformulation de requete et s'appuie sur une etude de concordance entre termes dans un ensemble de documents de reference.
A high-morbidity outbreak of methicillin-resistant Staphylococcus aureus among players on a college football team, facilitated by cosmetic body shaving and turf burns.

BACKGROUND Athletics-associated methicillin-resistant Staphylococcus aureus (MRSA) infections have become a high-profile national problem with substantial morbidity. METHODS To investigate an MRSA outbreak involving a college football team, we conducted a retrospective cohort study of all 100 players. A case was defined as MRSA cellulitis or skin abscess diagnosed during the period of 6 August (the start of football camp) through 1 October 2003. RESULTS We identified 10 case patients (2 of whom were hospitalized). The 6 available wound isolates had indistinguishable pulsed-field gel electrophoresis patterns (MRSA strain USA300) and carried the Panton-Valentine leukocidin toxin gene, as determined by polymerase chain reaction. On univariate analysis, infection was associated (P<.05) with player position (relative risk [RR], 17.5 and 11.7 for cornerbacks and wide receivers, respectively), abrasions from artificial grass (i.e., "turf burns"; RR, 7.2), and body shaving (RR, 6.1). Cornerbacks and wide receivers were a subpopulation with frequent direct person-to-person contact with each other during scrimmage play and drills. Three of 4 players with infection at a covered site (hip or thigh) had shaved the affected area, and these infections were also associated with sharing the whirlpool > or =2 times per week (RR, 12.2; 95% confidence interval, 1.4-109.2). Whirlpool water was disinfected with dilute povidone-iodine only and remained unchanged between uses. CONCLUSIONS MRSA was likely spread predominantly during practice play, with skin breaks facilitating infection. Measures to minimize skin breaks among athletes should be considered, including prevention of turf burns and education regarding the risks of cosmetic body shaving. MRSA-contaminated pool water may have contributed to infections at covered sites, but small numbers limit the strength of this conclusion. Nevertheless, appropriate whirlpool disinfection methods should be promoted among athletic trainers.
Sumatriptan: a review of its pharmacokinetics, pharmacodynamics and efficacy in the acute treatment of migraine

Introduction: Sumatriptan was developed more than 20 years ago as a 5-HT1B/1D receptor agonist, the first drug in a new class of specific anti-migraine drugs, the triptans. A large amount of information and experience has been gained from the clinical trials undertaken as well the various formulations of sumatriptan used over this period of time. Areas covered: This evaluation specifically reviews the pharmacokinetics, pharmacodynamics, clinical efficacy, and safety of different formulations and dosages of sumatriptan used for the acute treatment of migraines. Special clinical trials of the timing of dosage and sumatriptan in combination with other triptans as well as non-triptan drugs are also included. Expert opinion: Oral sumatriptan is effective, but not in a convincing majority (60%) of patients in clinical trials. Sumatriptan has failed to show superiority over more standard and cheaper treatment such as aspirin or aspirin plus metoclopramide. In addition, migraine patients want to quickly become pain free, and to remain pain free, but oral sumatriptan at 100 mg managed to keep patients pain free for 24 h is only 20% of cases. Even though sumatriptan has been a major step forward in providing a new specific therapy for the treatment of migraines, there are still are limitations in its use. There is still an unmet need to develop new non-triptan, anti-migraine drugs which act as effective treatment for those who suffer with migraines.
Oscillations can reconcile slowly changing stimuli with short neuronal integration and STDP timescales

Oscillatory brain activity has been widely reported experimentally, yet its functional roles, if any, are still under debate. In this review we argue two things: firstly, thanks to oscillations, even slowly changing stimuli can be encoded in precise relative spike times, decodable by downstream “coincidence detector” neurons in a feedforward manner. Secondly, the required connectivity to do so can spontaneously emerge with spike timing-dependent plasticity (STDP), in an unsupervised manner. The key here is that a common oscillatory drive enables neurons to remain under a fluctuation-driven regime. In this regime spike time jitter does not accumulate and can thus be lower than the intrinsic timescales of stimulus fluctuations, which leads to so-called “temporal encoding”. Furthermore, the oscillatory drive formats the spikes in discrete oversampling volleys, and the relative spike times between neurons indicate the eventual differences in their activation levels. The oversampling accelerates the STDP-based learning for downstream neurons. After learning, readout only takes one oscillatory cycle. Finally, we also discuss experimental evidence, and the question of how the theory is complementary to the so-called “communication through coherence” theory.
Temporal Access to the Iteration Sequences: A Unifying Approach to Fixed Point Logics

The semantics of fixed point constructions is commonly defined in terms of iteration sequences. For example, the least fixed point of a monotone operator consists of all points which eventually appear in the approximations computed iteratively. We take this temporal reading as the starting point and develop a systematic approach to temporal definitions over iteration sequences. As a result, we propose an extension of first-order predicate logic with an iterative operator, in which iteration steps may be accessed by temporal logic formulae. We show that proposed logic FO+TAI subsumes virtually all known deterministic fixed point extentions of first-order logic as its natural fragments. On the other hand we show that over finite structures FO+TAI has the same expressive power as FO+PFP (FO with partial fixed point operator), but in many cases providing with more concise definitions. Finally, we show that the extension of modal mu-calculus with the temporal access leads to the more expressive logic closed under assume-guarantee specifications operator
Comparison of the Effects of Latanoprost and Bimatoprost on Central Corneal Thickness

PurposeTo compare the effects of latanoprost and bimatoprost on central corneal thickness (CCT). Materials and MethodsA total of 188 eyes of 94 patients who were being followed in our hospital's glaucoma clinic and were receiving either latanoprost (55.3%) or bimatoprost (44.7%) monotherapy were recruited for the study. The data were collected prospectively from the patients, who were medicated with bimatoprost or latanoprost, at the initial diagnosis of glaucoma. Measurements were performed at the initial diagnosis, 6th, 12th, and 24th months. All the measurements were carried out by the same doctor between 9 AM and 11 AM, using Goldmann applanation tonometer for intraocular pressure (IOP) and ultrasound biopachymeter for CCT. ResultsThere were no significant differences between the patient groups receiving latanoprost or bimatoprost for sex, age, baseline IOP, and CCT. The mean baseline CCT values were 559.5±35.3 μm for latanoprost group and 553.4±31.7 μm for bimatoprost group. CCT of both groups at 6, 12, and 24 months were significantly thinner when compared with baseline CCT. The percent reduction rates were 1.9±2.4% for latanoprost and 2.8±1.8% for bimatoprost in the 24th month. ConclusionA significant reduction in CCT was observed at the 6th, 12th, and 24th months with latanoprost and bimatoprost. Serial CCT measurements in determining the IOP values may be helpful in the follow-up of prostaglandin analogs.

Our Business Diagnostic Tool will be identifying the main aspects, activities and processes that would be able to secure value add into one-person's companies chain value that allow its sustainability in the time. Percentage results of the metrics evaluated from the attributes of interoperability, traceability and install ability showed a percentage over the average in the number of interface data that has been applied according to the specifications and the number of data exchanged between different components.
2.4/5 GHz Dual-Band Planar Antennas Mounted on WLAN Card for 3-MIMO-OFDM Systems

This paper proposes a 2.4/5-GHz dual-band horizontally-polarized planar antenna for use in a 3-MIMO antenna configuration OFDM wireless LAN (WLAN) system. The proposed antenna provides a voltage standing wave ratio of 2 in the 2.4-2.5 and 4.9-6 GHz bands when printed on a printed circuit board for commercial PCMCIA or WLAN cards and inserted into a notebook PC. The capacities and correlation coefficients of 3times3 MIMO channels in an indoor multipath LOS/NLOS environment were measured. The results show that the proposed planar antenna is superior to the conventional monopole antenna with respect to channel capacity when polarization matching between the base station and personal station antennas is obtained.
