Should psychiatrists ‘Google’ their patients?
Authors: Ashby G. Alice , O'Brien Aileen , Bowman Deborah , Hooper Carwyn , Stevens Toby , Lousada Esther
Published: December 2015

Since its beginnings in the 1980s the internet has come to shape our everyday lives, but doctors still seem rather afraid of it. This anxiety may be explained by the fact that researchers and regulatory bodies focus less on the way that the internet can be used to enhance clinical work and more on the potential and perceived risks that this technology poses in terms of boundary violations and accidental breaches of confidentiality. Some aspects of the internet's impact on medicine have been better researched than others, for example, whether email communication, social media and teleconferencing psychotherapy could be used to improve the delivery of care. However, few authors have considered the specific issue of searching online for information about patients and much of the guidance published by regulatory organisations eludes this issue. In this article we provide clinical examples where the question ‘should I Google the patient?’ may arise and present questions for future research.
Academic Imperialism; Or, Replacing Nonrepresentative Elites
Authors: Herlihy-Mera Jeffrey
Published: December 2015

Candidates from mid- and low-tier universities are not hired at top universities because they are not interviewed. The data in this article demonstrate that professors appointed to positions in the top tiers of US News and World Report and National Research Council rankings tend to be from one small sector of PhD-granting institutions; the enormous preference for elite affiliation in these hiring competitions has stratified the discipline to the point that just 1 percent of faculty at top-ranked English departments are graduates from the so-called bottom 75 percent of PhD-granting universities. This situation amounts to an ethical crisis, not just a labor one. The myth that “competition” is an appropriate mainstay for hiring is a toxic one for the humanities, as the process frequently fails: qualified candidates are unsuccessful not as a result of their own shortcomings but due to the ethically bankrupt nature of the competition itself. In the context of unethical admissions policies at top universities, widespread grade inflation, the slanted politics of recommendation letters, and search committees whom deny (and/or are unconscious of) the biases that dominate candidate valuation —this article poses an argument in favor of structural changes to the hiring process that would democratize faculty bodies at so-called top US institutions as well as throughout the academy.
The No-Prospect Poem
Authors: Hunter Walt
Published: December 2015

This essay considers how poems and lyrical prose by J. H. Prynne, Kofi Awoonor, and Natasha Trethewey examine the conditions of possibility for a global subject in the light of finality: that which may no longer be prevented nor undone. Revising the tradition of the locodescriptive lyric and the prospect poem, Prynne, Awoonor, and Trethewey use the hill as a location for staging the ethical dilemmas of the putative “global citizen.” From poetic hills in England, Ghana, and New Orleans, the view stretches to accommodate global suffering, inequality, and the lives of others, who, however far or close, shape the contours, the possibilities and dangers, of the poem's immediate vicinity. Far from offering spectatorial mastery to the poet, however, the hill is transformed into the ground and habitation of precarious life. The hill makes visible an alternative trajectory of contemporary lyric subjectivity in which the lyric's “I” emerges from and is shaped by the collective immiseration of neoliberal globalization.

Flaubert's Alibi: The Impossible Ensemble ofMadame Bovary
Authors: Creasy C.F.S.
Published: December 2015

The infamous fiacre passage of Flaubert's Madame Bovary, though suppressed by the editors of the Revue de Paris in the initial publication, nevertheless becomes crucial to the 1857 obscenity trial brought against the author and publishers. The absent passage circulates within the arguments of both the imperial prosecution and the defense, which thereby misrecognize and register the novel's mode of insinuating scandal without representing it. In the process, the trial's own discourse becomes entangled in that paraliptical mode, with the result that the novel and the trial form an inextricable aesthetic ensemble. This essay claims that this strange relationship has quietly shaped central categories of subsequent literary criticism. By reading the novel in the trial and the trial in the novel, the essay suggests a more nuanced sense of Flaubertian style—but also of the relationships between the literary and the institutions of the sociohistorical world.
Urine-derived induced pluripotent stem cells as a modeling tool for paroxysmal kinesigenic dyskinesia
Authors: Zhang Shu-Zhen , Li Hong-Fu , Ma Li-Xiang , Qian Wen-Jing , Wang Zhong-Feng , Wu Zhi-Ying
Published: December 2015

Paroxysmal kinesigenic dyskinesia (PKD) is a monogenic movement disorder with autosomal dominant inheritance. We previously identified the proline-rich transmembrane protein 2 (PRRT2) as a causative gene of PKD. However, the pathogenesis of PKD remains largely unknown so far. In addition, applicable modeling tools to investigate the underlying mechanisms of PKD are still lacking. The combination of disease-specific human induced pluripotent stem cells (iPSCs) and directed cell differentiation offers an ideal platform for disease modeling. In this study, we generated two iPSC lines from the renal epithelial cells of one PKD patient with the hotspot c.649dupC mutation (PKD-iPSCs). These cell lines were positive for alkaline phosphatase Nanog, Tra-1-80, Tra-1-60, SSEA-3 and SSEA-4. Teratomas with three blastoderms including ectoderm, mesoderm, and endoderm were obtained two months after injection of PKD-iPSCs into NOD/SCID mice. The expression of PRRT2 mRNA was decreased in PKD-iPSCs compared with that of the control iPSCs. Furthermore, PKD-iPSCs possessed the differentiation potential of functional glutamatergic, dopaminergic and motor neurons in vitro. Electrophysiological examinations revealed that the current densities of fast activated and deactivated sodium channels as well as voltage gated potassium channels were not different between the neurons from PKD-iPSCs and control iPSCs. Thus, PKD-iPSCs are a feasible modeling tool to investigate the pathogenic mechanisms of PKD.
Introducing Pitt-Hopkins syndrome-associated mutations ofTCF4toDrosophila daughterless
Authors: Tamberg Laura , Sepp Mari , Timmusk Tõnis , Palgi Mari
Published: December 2015

Pitt-Hopkins syndrome (PTHS) is caused by haploinsufficiency of Transcription factor 4 (TCF4), one of the three human class I basic helix-loop-helix transcription factors called E-proteins. Drosophila has a single E-protein, Daughterless (Da), homologous to all three mammalian counterparts. Here we show that human TCF4 can rescue Da deficiency during fruit fly nervous system development. Overexpression of Da or TCF4 specifically in adult flies significantly decreases their survival rates, indicating that these factors are crucial even after development has been completed. We generated da transgenic fruit fly strains with corresponding missense mutations R578H, R580W, R582P and A614V found in TCF4 of PTHS patients and studied the impact of these mutations in vivo. Overexpression of wild type Da as well as human TCF4 in progenitor tissues induced ectopic sensory bristles and the rough eye phenotype. By contrast, overexpression of DaR580W and DaR582P that disrupt DNA binding reduced the number of bristles and induced the rough eye phenotype with partial lack of pigmentation, indicating that these act dominant negatively. Compared to the wild type, DaR578H and DaA614V were less potent in induction of ectopic bristles and the rough eye phenotype, respectively, suggesting that these are hypomorphic. All studied PTHS-associated mutations that we introduced into Da led to similar effects in vivo as the same mutations in TCF4 in vitro. Consequently, our Drosophila models of PTHS are applicable for further studies aiming to unravel the molecular mechanisms of this disorder.
Opposition theory and computational semiotics
Authors: Assaf Dan , Cohen Yochai , Danesi Marcel , Neuman Yair
Published: December 2015

Opposition theory suggests that binary oppositions (e.g., high vs. low) underlie basic cognitive and linguistic processes. However, opposition theory has never been implemented in a computational cognitive-semiotics model. In this paper, we present a simple model of metaphor identification that relies on opposition theory. An algorithm instantiating the model has been tested on a data set of 100 phrases comprising adjective-noun pairs in which approximately a half represent metaphorical language-use (e.g., dark thoughts) and the rest literal language-use (e.g., dark hair). The algorithm achieved 89% accuracy in metaphor identification and illustrates the relevance of opposition theory for modelling metaphor processing.
Socio-cultural and ideological origins of homophobia in Russia
Authors: Зорина Наталья , Zorina Natalya , Кортунов Вадим , Kortunov Vadim , Краснова Ольга , Krasnova Olga , Котов Сергей , Kokotov Sergey
Published: December 2015

In 2013 the State Duma of Russian Federation adopted a Federal Law “banning propaganda of nontraditional sexual relations among minors». This law provoked great discussions between sexual minorities and their opponents in the media: the first began to criticize the Law as infringing upon their rights, others, after a long silence, resumed their attacks on the homosexuals. Due to such discussions Sociologists think that homophobia is reviving in Russia. According to the American psychological Association, only 16% of the population in modern Russia can accept homosexuality as the norm (against 60% in USA and 80% in Europe). This is the public opinion in Russia. And only such cautious, squeamish attitude toward those people as not quite healthy pones allows sociologists to talk about a revival of homophobic attitudes in our country. In the article authors make an attempt to understand the arguments of opponents of sexual orientation and to trace the ideological origins of “Russian homophobia”. For this, the authors of the research are trying to answer the questions: is it correct to justify homosexuality as normal behavior, referring to the homosexual behavior of animals, how is homosexuality caused by norms of Russian culture, what is its contribution to the arts, what do world religions say about same-sex relationships, what is its impact on the development of the society, what does the modern medicine think about this phenomenon. There is an attempt to reproduce the logic of homophobic arguments, so common today in Russia, to understand its origins and ideological Foundation. This is done only for the purpose of finding compromises and developing balanced, tolerant positions on both sides. The authors hope that considerations expressed in the article will be useful in resolving such an important social and cultural issue as a confrontation between homosexuals and heterosexuals, and will make the contribution to the guarantees of rights and freedoms in the Russian Federation.
Strategic Entrepreneurship in the Hotel Industry: The Role of Chain Affiliation
Authors: Карлбак Мэтс , Karlbak Mets
Published: December 2015

Аbstract. The aim of this paper is to identify why independent hotels decide to affiliate and give up their highly valued independence. Based on interviews with 12 independently owned hotels and five affiliations active on the Swedish market, it became evident that independence is important, but factors such as development with technical solutions, internet, the use of smart phones, social media, sales and marketing, central purchasing and loyalty cards are difficult to pursue as an independent hotel. The results also showed that marketing organisations and referral chains are the preferred options, as their offerings are more in line with the view of strategic entrepreneurship that the hoteliers expressed. Even agencyrelated aspects such as control rights affected the entrepreneurs’ aspiration to affiliate, at the same time as the respondents thought their way of running the business was the most efficient. The results from the research add to the knowledge associated with agency theory, strategic entrepreneurship and resource-based view of the firm. More practically, it gives the independent hoteliers a possibility to assess the current situation and decide what options could be valuable, while the affiliations would be able to better align their offerings to attract new hotels.

Published: December 2015

The educational program «Management in Tourism and Hospitality» implemented at the Federal State-Funded

Educational Institution of Higher Professional Education «Russian State University of Tourism and Service» is

constructed in such a way that the primary emphasis is placed upon the management processes in the organizations.

That said, a number of the competences containing the requirements as to the training for professional

activities in the bodies of state and municipal administration (in particular, in tourist administrations) may be

insufficiently mastered by the graduates. For example, the competences related to the organization and regulation

of service activities. As far as is known, in the current context the service component in a tourist product is the

important factor affecting its competitiveness. The introduction of discipline «Service Quality and Design» into the

curriculum will allow to change to some extent the current situation. This discipline will help students to acquire

expertise, knowledge and skills regarding the existing concepts of service activities; the methods of service activities

organization in tourism and hospitality; the service management and its role in the improving competitiveness of a

tourist product, tourism organization and tourist destination as a whole.

Background: The level of lymph node involvement is the most important factor in staging colorectal cancer without metastasis. Sentinel lymph node mapping identifies the node(s) that most accurately reflect the lymph node status of patients and intensive techniques that improve staging can be focused on these nodes. Objective: The aim of this study was to assess the efficacy of ex vivo sentinel lymph node mapping in the staging of colon cancer. Design: The selection of the cohorts was carried out on a prospective basis from September 2009 to April 2013, including all cases with no randomisation. Settings: Patients from the Alava University Hospital health region (Alava–Basque Country) in Spain. Patients: Study of 250 patients diagnosed prior to surgery with colon cancer without distant metastasis. A comparative study was also performed based on a control group of 170 patients staged with conventional techniques, involving a single slice and haematoxylin-eosin staining, from June 2006 to February 2009. Interventions: In these patients, we used ex vivo sentinel lymph node mapping with methylene blue, studying the sentinel nodes with multiple slices and immunohistochemical techniques as well as haematoxylin-eosin staining. Main outcome measures: The main outcome variable was change in staging after the Sentinel lymph node mapping. Results: The Sentinel lymph node identification rate was 98%, with 3.7% of false negatives. Upstaging occurred in 11% of cases compared to the group studied using conventional techniques. Limitations: The patients are not randomly selected and are compared with a retrospective series. Conclusions: Ex vivo Sentinel lymph node mapping with methylene blue accurately reflects the lymph node status of patients with colon cancer. This approach upstages patients classified as stages I and II by conventional techniques to stage III, indicating chemotherapy that may improve their prognosis.

Producción anfórica en la costa malacitana desde la época púnica hasta el periodo julioclaudio
Authors: Mateo Corredor Daniel
Published: December 2015

El estudio de la producción anfórica en el litoral malacitano durante las épocas púnica y republicana apenas ha sido tratado por la historiografía, situación que para la antigua Malaca se está empezando a invertir en los últimos años. Durante el estudio de conjuntos anfóricos inéditos de diversas intervenciones procedentes de la bahía de Málaga y de Cerro del Mar (Torre del Mar, Málaga), hemos documentado hallazgos que nos permiten avanzar en el conocimiento tipológico y arqueométrico de estas producciones, que no parecen verse alteradas tras la conquista romana. Asimismo, hemos registrado ánforas de este origen en otros puntos del mediodía peninsular, lo que nos permite realizar un primer acercamiento a la importancia cualitativa y cuantitativa de sus exportaciones. Mostramos que, para el periodo analizado, el dinamismo del ámbito productivo de la costa mediterránea del sur de la península ibérica en general, y del litoral malacitano en particular, es mayor al reflejado en la literatura científica, confirmándose como un área relevante para la comprensión de la economía de Hispania Ulterior/Bética.

Clinical and Pathological Parameters Predicting Extracapsular Disease in Patients Undergoing a Radical Prostatectomy for Clinically Localized Prostate Cancer
Authors: Sfoungaristos Stavros , Perimenis P.
Published: December 2015

To determine the epidemiological, clinical and pathological factors that can potentially predict extracapsular extension of prostate cancer in patients undergoing radical prostatectomy for clinically localized disease. We retrospectively analyzed the medical records of patients who undergone radical prostatectomy from January 2001 until November 2010. Patients age, prostate volume, PSA, PSA density, percent of cancer in prostate biopsy material, presence of cancer in biopsy cores of the right lobe or the left lobe or both lobes, Gleason summary, 1st Gleason pattern and 2nd Gleason pattern were analyzed for their predictive ability. From 187 studied patients, 44 of them (23.5%) had extracapsular disease. Multivariate analyses revealed that smaller prostate volumes and the presence of malignancy in both lobes after prostate biopsy were significant predictors for non-organ confined disease in the total population and in patients with Gleason score ≥7. Presence of malignancy in both lobes was the only significant predictive factor in patients with PSA ≤10 and in those with Gleason score ≤6. Prostate volume and positive cores for malignancy from both lobes after prostate biopsy are preoperative data that can be used for prediction of extracapsular disease. This information can be valuable in cases a nerve sparing radical prostatectomy is planned.

Authors: Šebková S. , Tomek V. , Zemanová P. , Janota Jan
Published: December 2015

A term newborn with a hypocontractile myocardium complicating persistent pulmonary hypertension of the newborn was successfully treated with a low-dose phosphodiesterase III inhibitor milrinone. Echocardiography diagnosed heart failure with a left ventricular ejection fraction of 35% and a left ventricular shortening fraction of 18% and severe persistent pulmonary hypertension of the newborn with oxygenation index of 28. Milrinone was started at an initial dose of 50 mcg/kg, followed by continuous infusion of 0.20 mcg/kg/min. With lowdose milrinone oxygenation index decreased to 3 within 6 hours, left ventricular ejection fraction and left ventricular shortening fraction increased to 57%, and 30%, respectively. Low doses of milrinone might be promising in the treatment of heart failure and persistent pulmonary hypertension of the newborn in term newborns.
Arteriovenous Fistula after Femoral Artery Puncture Leading to Pulmonary Edema: The Role of Ultrasonography
Authors: Malík Jan , Holaj R. , Krupičková Z. , Janota T.
Published: December 2015

Local complications of arterial puncture include hematoma, pseudoaneurysm and formation of arteriovenous fistula (AVF). The latter could cause ischemia of the particular extremity or can be hemodynamically significant especially in patients suffering from congestive heart failure. We report a case of femoro-femoral AVF after thin needle arterial puncture for blood drawing. The development of this iatrogenic AVF led to pulmonary edema. The patient stabilized completely after surgical closure of the AVF. The AVF was diagnosed by duplex Doppler ultrasonography and this method was also used for estimation of blood flow through the AVF. We discuss the role of ultrasound AVF diagnostics and the method of flow calculation.

Published: December 2015

Conventional and modern methods of radiological imaging are often used in the diagnosis of temporomandibular joint disorders, and the CT technique is particularly characterized by an excellent visualization of bony structures. The aim of the study was to show the importance and role of CT in the evaluation of TMJ bone structures in both patients with articular disc displacement and in a group of healthy subjects. Both study groups were assessed with the use of the transverse plane. Herein, multi-slice spiral computed tomography was performed in 47 subjects. These individuals were qualified for CT by way of magnetic resonance imaging, due to their being diagnosed with a displacement of their temporomandibular joint disc. The product of our study is presented as a set of tables. These are comparisons of radiological parameters based on the shape, size and location of the mandibular head, in the examined patients, in a control group, and with regard to sex. The results of our work indicate that CT can be successfully used in the imaging of TMJ bone structures, specifically, the condylar process of the mandibular head and the joint socket. However, statistically significant differences of the utilized parameters between patients with articular disc displacement and controls, warrant further analysis of this issue.
Design Considerations for Optimal Absorption of Energy from a Vibration Source by an Array of Harvesters
Authors: Sriramdas Rammohan , Rastogi Shreevar , Pratap Rudra
Published: December 2015

Dynamic vibration absorption is a passive technique for suppressing unintended vibrations. Optimal absorption of energy from a vibration source entails the determination of absorber parameters such as resonant frequency and damping. In the present work, we propose a method to obtain these parameters for a generic case of large number of identical vibration absorbers placed on a vibration source. We discuss an iterative procedure to find the optimum absorber resonant frequency and damping by minimizing the total energy absorbed by the system. We also analyse the influence of damping of the entire set of absorbers on the total energy absorbed and the effect of the absorber mass on the bandwidth of absorption. The proposed method is verified by analysing the response of a set of cantilever absorber beams placed on a vibrating cantilever plate. The resonant frequencies of the system with different number of absorbers are verified experimentally. We identify, using our method, the absorber mass, resonant frequency and damping of the absorber at which significant amount of energy supplied to the system flows into absorbers. A potential application of this method in the context of energy harvesting is the design of harvesters for a given vibration source. We emphasize through our work that monitoring energies in the system and optimizing them is both rational and vital for designing multiple harvesters that absorb energy from a given vibration source optimally.
Compact Bandpass Filter Based on Parallel-coupled Lines and Quasi-lumped Structure
Authors: Ding Chen , Li Jiao , Wei Feng , Shi Xiao-Wei
Published: December 2015

A compact microstrip bandpass filter (BPF) using quarter-wavelength resonators is proposed based on the parallel-coupled lines (PCLs) and quasi-lumped structure. A method based on the matrix and network transformation of cascaded-quadruplet (CQ) filters is investigated and successfully applied to the BPF design. The design formulas for the proposed BPF are analytically developed. Specifically, in order to verify the feasibility of the proposed method, three BPFs centering at 1.575 GHz with different FBWs are designed. Good agreement between the simulated and measured results is observed. Moreover, the designed filters can achieve a wide stopband.
Statistical Beamforming for Interference Mitigation in Multi-cell Massive MIMO Systems
Authors: Hu Anzhong
Published: December 2015

This paper proposes a statistical beamforming approach to mitigate interference in multi-cell massive multiple-input multiple-output systems. The proposed approach projects the signal subspace onto the null space of the interference to form the weight vector with the statistical channel state information. In contrast to the existing methods which only utilize the partial null space of the interference, the proposed approach can collect more signal when mitigating the interference. In addition, the large system analysis demonstrates that the interference is eliminated with uniform rectangular arrays. Numerical results show that the proposed approach can achieve higher sum rate than the existing methods and verify the performance analysis.

Authors: Qi Rong-Sheng , Jin Miao , Guo Bao-Feng , Liu Xin-Gang , Chen Lei
Published: December 2015

The compressive deformation behaviors of 410 martensitic stainless steel were investigated on a Gleeble-1500 thermomechanical simulator, and the experimental stress–strain data were obtained. The measured flow stress was corrected for friction and temperature. A constitutive equation that accounts for the influence of strain was established, and the hot-processing maps at different strain were plotted. The microstructure evolution of the hot-deformation process was studied on the basis of microstructural observations at high temperatures. Phase-transformation experiments on 410 steel were conducted at high temperatures to elucidate the effects of temperature on the delta-ferrite content. The initial forging temperature and optimum process parameters were obtained on the basis of the processing map and the changes in the delta-ferrite content at high temperatures.
Web tracking: Overview and applicability in digital investigations
Authors: Pugliese Gaston
Published: December 2015

Nowadays, website owners, advertisers, and data vendors can draw on a variety of techniques to track users on the Web. Here, the tracking range can vary from single websites to long-term browsing sessions across several websites and devices. Even though they are widely used, most of these techniques have in common that they are not familiar to average and even web-minded users. Therefore, most users are not able to realize the magnitude of web tracking and its consequences, not to mention to resist tracking. In times of rising concerns about data protection and privacy, this paper is intended to illustrate how web tracking works and which standard techniques are commonly used. The paper also provides an outlook on promising new tracking techniques based on behavioral biometrics. Furthermore, since browser forensics is already a subject to digital investigations, the usefulness of tracking techniques for forensic purposes and their applicability in light of the principle of proportionality is discussed. Finally, possible countermeasures and their effectiveness are indicated.
Global uniqueness and stability in determining the electric
potential coefficient of an inverse problem for Schrödinger
equations on Riemannian manifolds
Authors: Triggiani Roberto , Zhang Zhifei
Published: December 2015

In the present paper, we consider the inverse problem of a Schrödinger equation
defined on an open, bounded, connected set Ω of a complete,
n-dimensional Riemannian manifold M with metric g. It is subject
to a non-homogenous Dirichlet boundary term. We aim at determining
the potential coefficient by means of a Neumann boundary measurement
on a portion Γ1 of the boundary Γ of Ω. Under
sharp conditions on the complementary part Γ0 = Γ∖Γ1, and under weak regularity requirements on the data, we
establish two canonical results of the inverse problem: (i) global
uniqueness and (ii) global Lipschitz stability. The lower bound
inequality corresponding to the upper bound inequality contained in

Retro-Innovation and Corporate Social Responsibility
Authors: Loucanova Erika , Parobek Jan , Kalamarova Martina
Published: December 2015

The paper deals with the retro-innovation and their importance to corporate social responsibility (CSR). Corporate social responsibility is a process with the aim to encourage a positive impact through activities on the environment, consumers, employees, communities, and all other stakeholders of the public sphere. The accelerated rate of technological and social change influences on the society. The main social problems are symptoms of future shock. Retro-innovation trend is emerging against an accelerating backdrop of “datafication”. New products are designed to connect customers with the past in ways that are nostalgic, interactive and environmental. CSR thanks to the retroinnovation encourages has a positive impact on the all stakeholders and eliminates the future shock.

Published: December 2015

The article is based on a study of the structural funds used in Romania during 2007-2014. The analysis examines all the programs carried out in the mentioned period in Romania. The study focuses on several indicators personally elaborated, which are meant to reveal the major differences between the operational programs and in each operational program by itself by comparing the ratios resulted. This research can be considered as an objective summarized examination of the first stage of EU funding in Romania.
Aeschylus and the Beginning of Tragic Reperformances
Authors: Lamari Anna A.
Published: December 2015

This chapter surveys the evidence for the reperformances of the works of Aeschylus from as early as the fifth century. Through a discussion of testimonies from the ancient biographers, ancient scholiasts, Herodotus, Philostratus, but also the fifth-century comedians, I attempt to highlight the (re)performative importance of Aeschylean tragedy in theatrical history and to show that restagings of drama started occurring during Aeschylus’ lifetime and were systematically developed after his death in 456.

Short-latency afferent
inhibition in chronic spinal
cord injury
Authors: Bailey Aaron Z. , Mi Yiqun P. , Nelson Aimee J.
Published: December 2015

Background: Short-latency afferent inhibition (SAI) results when somatosensory afferent input inhibits the
corticospinal output from primary motor cortex (M1). The present study examined SAI in the flexor carpi radialis
(FCR) muscle in individuals with spinal cord injury (SCI) and uninjured controls. Methods: Short-latency afferent
inhibition (SAI) was evoked by stimulating the median nerve at the elbow at intervals of 15, 20 and 25 ms in
advance of a transcranial magnetic stimulation (TMS) pulse over M1. SAI was tested with the FCR at rest and
also during ~20% of maximum voluntary contraction. Corticospinal output was assessed through measuring
both motor thresholds and motor evoked potential (MEP) recruitment curves. The afferent volley was assessed
via the N20-P25 amplitude of the somatosensory evoked potential (SEP) and the amplitude of sensory nerve
action potentials (SNAP) recorded over the median nerve at the elbow. Results: SAI is reduced in SCI in both the
contracted and non-contracted FCR muscle. MEP recruitment curves and thresholds were decreased in SCI only
in the active state and not the resting state. N20-P25 amplitude was similar between groups in both the resting
and active states although SNAP was significantly reduced in SCI at rest. Conclusions: We conclude that reduced
SAI in SCI is likely attributed to neuroplasticity altering the intrinsic M1 circuitry mediating SAI and/or reduced
afferent input traversing a direct thalamocortical route to M1. These data provide a new avenue of research aimed
at identifying therapeutic approaches to alter SAI to improve upper limb function in individuals with SCI.
Grammatischer Wandel im (Mittel-)Neuhochdeutschen – von oben und von unten. Perspektiven einer Historischen Soziolinguistik des Deutschen
Authors: Elspaß Stephan
Published: December 2015

The present contribution addresses the phenomenon of grammatical change using a historical sociolinguistic approach, which is based on the principle that systematic language change can only be described and explained by accounting for sociopragmatic and variational factors of language use. The approach is illustrated by an empirical investigation of the change of selected morphological and syntactic features in (Middle) New High German, using Labov’s distinction between ‘language change from above’ and ‘language change from below’ as a starting point of analysis. The aim of the paper is to demonstrate that the historical sociolinguistic approach not only complements other methods of historical linguistics, but may also lead to results and findings that could perhaps not be achieved by other methodological approaches. Moreover, it is considered central to the description and explanation of the development of language varieties in periods of language standardisation.
Die Historische Syntax des Deutschen braucht die Sprachtypologie – und umgekehrt
Authors: J. Simon Horst
Published: December 2015

In this paper I try to demonstrate the benefits of interaction between the fields of historical syntax of German on the one hand and linguistic typology on the other hand. Using four examples for each direction, I argue that both fields need each other’s input: German historical syntax can learn to avoid various forms of parochialism, and at the same time it can feed its vast amount of detailed knowledge into discussions of general linguistics.
Historische Syntax des Deutschen aus generativer Perspektive
Authors: Axel-Tober Katrin
Published: December 2015

This paper summarizes recent advances in research on the diachronic syntax of German from a generative perspective on the basis of three case studies. The first case study focuses on the sentence grammar of early German and argues that generalized V(erb)-to-C(omp)-movement, the core property of the verb-second phenomenon, goes back to Old High German times. In contrast to English, German has thus not been subject to a resetting of the verb-second parameter. Two further case studies deal with null subjects in Old High German and the diachrony of sentence negation, thereby addressing the issues of change in surface manifestations in relation to the underlying syntactic representation and the relation between historical syntax and dialect syntax.
Mathematical crystallography in the 21st century
Authors: Senechal Marjorie
Published: December 2015

As crystallography merges with materials science and engineering, mathematical crystallography is growing in new directions, including: Characterizing new materials with unusual properties; Imaging, including but not limited to diffraction; Exploring and exploiting superspaces; Mapping the aperiodic landscape, from chaos to classical periodicity and beyond; Re-modeling the structures of real crystals, both periodic and aperiodic; Modeling self-assembly and self-reorganization on the nanoscale. In short, it’s not (just) about space groups and tilings anymore.
Development and Implementation Results of a Venous Thromboembolism Prophylaxis Guideline in a Tertiary Care Pediatric Hospital
Authors: Mahajerin Arash , Webber Emily C. , Morris Jennifer , Taylor Kathryn , Saysana Michele
Published: December 2015

OBJECTIVES:

Incidence of pediatric venous thromboembolism (VTE) is increasing due to increased survival of children with chronic diseases and use of interventions (eg, central venous lines), with VTE risk. Our objective was to create VTE prophylaxis guidelines with targeted identification of children at high risk to support appropriate mechanical and pharmacologic prophylaxis and integrate into the electronic medical record (EMR) as a hospital-wide quality improvement project.

METHODS:

Patients aged 12 to 17 years were included. We evaluated institutional data regarding VTE incidence and risk factors. We evaluated literature for populations at high risk for VTE. Guidelines were formulated, and an EMR tool to assess risk and support the guidelines was created and implemented.

RESULTS:

The EMR tool was used to screen 48% of qualified admissions for the first month and 81% in the final study month. On average, 69.1% of qualified admissions were screened monthly during the first 18 months of the program. No adverse events were reported due to pharmacologic prophylaxis.

CONCLUSIONS:

Many risk factors are common between children and adults and certain pediatric populations warrant prophylactic consideration. Pediatric VTE prophylaxis guidelines can be successfully implemented into the EMR to identify high-risk populations. Future studies should assess the long-term impact of implementation.
