Innovating in hard time. Spanish firms under pressure in the Cold War
Authors: Calvo Calvo Ángel Amado
Published: June 2016

The article analyses the situation that confronted and answers that held various Spanish companies in high technology sectors during the Cold War, primarily due to two factors. On the one hand, under conditions of rapid technology changes on the Spanish companies were a clear technological dependency on multinationals. On the other hand, Cold War was interfering in trade relations with serious obstacles to the normal functioning of the market economy. This contribution fits into the integrative and interdisciplinary approach established by Segreto almost four decades after the work of Adler-Karlsson, considered as a pioneer in the field. The condition of Spain as a peripheral country and the diversity of the companies analyzed are important aspects to consider. The work updated bibliography and incorporates new primary sources, including the business and the official.
Factors Associated With Narcotic Use After Clavicle Fractures
Authors: Weinberg Douglas S. , Napora Joshua K. , West William H. , Grimberg Dominic C. , Vallier Heather A.
Published: June 2016

Clavicle fractures are common in adults. Recent studies have shown that operative treatment of clavicle fractures has benefits in many situations. However, there is controversy about the indications. Data on social outcomes are limited. A total of 434 patients with 436 clavicle fractures treated both operatively and nonoperatively at a level 1 trauma center were identified. Narcotic use was recorded 2, 4, 6, 8, 10, 12, 14, and 16 weeks after injury for both treatment groups. Other descriptive data included age, sex, laterality, hand dominance, rib fractures, smoking, alcohol use, employment, long bone or spine fracture, open clavicle fracture, and mechanism of injury. Logistic regression analysis was performed to determine the independent predictors of narcotic use after clavicle fracture. Open reduction and internal fixation was performed in 105 fractures (24%), and 329 fractures were managed nonoperatively. A total of 154 patients (35%) reported some narcotic use 2 weeks after injury, and 15% were still using narcotics 16 weeks after injury. Narcotic use decreased over time in patients treated with open reduction and internal fixation (10% vs 15% after nonoperative management). Patients treated with open reduction and internal fixation reported reduced narcotic use at 16 weeks (odds ratio [OR], 0.454;
P
=.070). Concurrent rib fracture (OR, 5.668;
P
<.001), smoking (OR, 3.095;
P
=.013), unemployment (OR, 5.429;
P
<.0005), and long bone or spine fracture (OR, 6.761;
P
<.001) were predictors of narcotic use. Further studies of the social, economic, and financial outcomes of clavicle fracture and osteosynthesis are warranted. [

Antidepressant, Antipsychotic, and Hallucinogen Drugs for the Treatment of Psychiatric Disorders: A Convergence at the Serotonin-2A Receptor
Authors: Howland Robert H.
Published: June 2016

Antidepressant, atypical antipsychotic, and hallucinogen drugs mediate their actions in part by interactions with the serotonin-2A (5HT2A) receptor. Serotonergic hallucinogen drugs, such as psilocybin, bind most potently as agonists at the 5HT2A receptor, producing profound changes in perception, mood, and cognition. Some of these drugs have been or are currently being investigated in small Phase 2 studies for depression, alcoholism, smoking cessation, anxiety, and posttraumatic stress disorder. However, unlike the synergistic effects of combining antidepressant and atypical antipsychotic drugs, the potential therapeutic effects of hallucinogen drugs may be attenuated by the concurrent use of these medications because antidepressant and atypical antipsychotic drugs desensitize and/or down-regulate 5HT2A receptors. This finding has important implications for optimizing the potential therapeutic use of hallucinogen drugs in psychiatry. [

Carotid Stent Fracture from Stylocarotid Syndrome
Authors: Hooker Jeffrey , Joyner David Andrew , Farley Edward Patrick , Khan Majid
Published: June 2016

Eagle syndrome is a rare condition resulting from elongation of the temporal styloid process or calcification of its associated stylohyoid ligaments. Although usually presenting with pain or odynophagia, Eagle syndrome has been reported to cause a multitude of neurologic symptoms or vascular complications, some of which can be life-threatening. We present a case in which an endovascularly placed internal carotid artery stent in close proximity to a calcified stylohyoid ligament resulted in stent fracture with subsequent stent and vessel occlusion. We review and discuss the presentation, diagnosis, etiology, complications and treatment options of the syndrome.
Incisional Hernia Following Ventriculoperitoneal Shunt Positioning
Authors: Bonatti Matteo , Vezzali Norberto , Frena Antonio , Bonatti Giampietro
Published: June 2016

Incisional hernia represents a rare complication after ventriculoperitoneal shunt positioning due to failure of the fascial suture in the site of abdominal entrance of ventriculoperitoneal catheter. Clinical presentation can be extremely variable, according to patient's performance status, herniated material constitution (i.e. mesenteric fat, bowel loops or both) and complication occurrence (e.g. strangulation or intestinal obstruction). Early diagnosis is fundamental in order to surgically repair the defect and prevent further complications. We present the case of a paucisymptomatic incisional hernia following ventriculoperitoneal shunt positioning. Diagnosis was made by means of ultrasound and confirmed by means of computed tomography. The patient was successfully managed by means of surgical repositioning of herniated loop and re-suture.

Published: June 2016

Small bowel perforation is a rare complication of ventriculoperitoneal (VP) shunt placement. When seen, it most commonly affects the stomach or colon. We describe a case and image findings of an 8-year-old female who presented with sepsis and erosion of the VP shunt into the small bowel. The imaging findings were confirmed surgically. We also provide an overview of the current literature discussing previously reported cases, clinical features, and treatment.
Intra-articular osteoid osteoma at the femoral trochlea treated with osteochondral autograft transplantation
Authors: Leeman Joshua J. , Motamedi Daria , Wildman-Tobriner Ben , O'Donnell Richard J. , Link Thomas M.
Published: June 2016

We present the case of an intra-articular osteoid osteoma at the femoral trochlea. Intra-articular osteoid osteoma can present a diagnostic challenge both clinically and with imaging because it presents differently from the classic cortical osteoid osteoma. Given the lesion's proximity to overlying cartilage, the patient underwent resection of the lesion with osteochondral autograft transplantation at the surgical defect. A comprehensive literature review and discussion of intra-articular osteoma will be provided.
Data Publish/Subscribe with Network Coding in DTN
Authors: Yi Xia , Guanghong Deng
Published: June 2016

A data Publish/Subscribe method with network coding (DPS-NC) used in delay tolerant network is proposed. Based on the publish/subscribe mechanism, the topic data were encoded and transmit with random network coding method, which can take full advantage of the network capacity to multicast. At the same time, for working out the problem of large data redundancy and vast invalid de-liveries in the network coding broadcast process, a packet routing scheme based on ant colony algorithm was brought. In the end, some simulation experiments are carried out and results show that the DPS-NC method can get better delivery performance.
Using UML Models to Describe the VISIR System
Authors: Mohmed Salah Razwan , Alves Gustavo R. , Guerreiro Pedro , Gustavsson Ingvar
Published: June 2016

Analysis and design are important phases in the system development lifecycle. In these phases, developers record information necessary for properly understanding the nature of the systems under consideration.We consider a particular type of system, named Remote Lab that allows both teachers and students to perform real experiments over the internet and we focus on Virtual Instrument Systems in Reality (VISIR).  We describe a summarized web interface of VISIR using the Unified Modeling Language (UML). Our case study aims at identifying the requirements of VISIR and at creating a set of UML diagrams that succinctly provide enough information to both developers and users so that they acquire enough information for building a general understanding of it. Additionally, we provide elements for extending UML to better support further user interface development in VISIR.

Dissipative forces and their work as a transformation of the macroscopic mechanical energy into the energy of thermal movement are decisive in the study of mechanical phenomena of real world. The remote experiment should both qualitatively and quantitatively describe the transformation of macroscopic kinetic energy into heat and show the quantities, active in the transformation. The remote experiment represents a new generation of ISES remote experiments. The measureserver is equipped with a new diagnostics block, enabling diagnosis information on remote experiments both for the client and the provider.
Les fattara du ramadhân au Maghreb ou l’hétéropraxie religieuse au prisme des normes sociales et juridiques
Authors: Papi Stéphane
Published: June 2016

Le jeûne du mois de ramadhân constitue le quatrième pilier de l’islam et revêt une dimension communautaire très marquée dans les trois pays du Maghreb (Algérie – Maroc – Tunisie), ce qui n’empêche pas que l’attitude des fattara choisissant délibérément de ne pas jeûner est tolérée quand elle reste cantonnée à la sphère privée. Elle entraîne cependant des problématiques religieuses et juridiques importantes quand elle s’exprime sur la place publique et qu’elle devient une instruction politique voire, comme ces dernières années, une revendication sociale fondée sur le respect de la liberté d’opinion et d’expression. À la faveur de l’individualisation des pratiques religieuses, celle-ci peut également s’exprimer au nom de la liberté de religion.
L’invention du culte musulman dans l’Algérie coloniale du xixe siècle
Authors: Saaidia Oissila
Published: June 2016

L’une des conséquences de la conquête de l’Algérie a été de mettre les autorités françaises devant l’obligation de gérer simultanément les trois principales religions monothéistes, et cela dans un contexte colonial unique au sein de l’empire français. Dans la mesure où l’Algérie est organisée en départements dans lesquels toutes les lois sont – en théorie – rendues applicables par décret, l’organisation des cultes est tributaire d’un cadre conçu pour la métropole. Si pour le catholicisme, le protestantisme et le judaïsme le transfert de ce cadre peut sembler aller de soi, malgré des réticences, qu’en est-il de l’islam, religion des colonisés ? La mise en place du culte musulman dans l’Algérie coloniale du xixe siècle a été conditionnée par une double contrainte : celle du contrôle de l’islam considéré comme l’obstacle majeur à la domination française et celle de la gestion du fait musulman en contexte pluriconfessionnel. Pour faire face à cette situation, les agents de l’administration – militaire et civile – ont développé différentes stratégies dans un contexte de conquête, à partir de leurs connaissances des populations et de leurs propres techniques administratives. Ce processus conduit à s’interroger sur les mécanismes qui ont mené à l’invention et à la construction du culte musulman, à identifier les artisans de cette transformation et à en repérer les fondements juridiques et administratifs. C’est pourquoi l’article s’intéresse aux conditions de la mise en place du culte musulman, à son organisation et à son évolution de 1830 à 1914, mais avance aussi quelques pistes d’interprétation sur le régime des cultes en Algérie et sur ces avatars dans la France du début du xxie siècle.
Sécurité aux frontières : Portée et limites de la stratégie algérienne
Authors: Benantar Abdennour
Published: June 2016

Le présent article analyse la stratégie algérienne de sécurité aux frontières dont l’instabilité accrue fait de l’Etat algérien l’un des plus engagés dans la sécurité régionale. Le pays fournit des efforts de guerre sans être en guerre. Dans le contexte des crises libyenne et malienne, la sécurité aux frontières est devenue une préoccupation majeure des autorités algériennes. Cette question fait aussi l’objet d’un processus de construction et de sécuritisation, à des fins internes et externes. L’article analyse, d’une perspective constructiviste, les aspects construit et instrumental des différentes notions (sécurité, menace, frontière, terrorisme). La stratégie algérienne se déploie sur trois niveaux : la mise en place d’un dispositif de sécurité aux frontières et la restructuration des forces armées et de sécurité ; l’amorce de processus bilatéraux de coopération avec les pays voisins ; le développement d’un processus multilatéral à travers l’initiative des pays de Champ. Cette stratégie est guidée par trois principes fondamentaux : non ingérence dans les affaires intérieures des Etats ; non intervention de l’armée algérienne hors du territoire ; prise en charge endogène de la sécurité régionale (refus de toute intervention extérieure). Malgré son apport à la sécurisation de la bande frontalière, cette stratégie reste limitée et ce pour diverses raisons : une orientation statocentrée dans le traitement de certains questions ; caractère inopérant de certains principes cardinaux dans un environnement évolutif caractérisé par l’affirmation des acteurs non-étatique ; mutations du phénomène terroriste ; un contexte régional hautement instable ; absence de convergence stratégique dans la région.
Le national à distance. Circulation de normes et réécriture du politique de la Tunisie
Authors: Pouessel Stéphanie
Published: June 2016

Cet article questionne le corps national et les lieux extraterritoriaux de formation du politique. La scène politique post-2011 a inauguré une refonte des élites parlementaires et gouvernementales. Les « Tunisiens de l’étranger » qui représentent 10 % de la population tunisienne, ont été intégrés au processus démocratique qui a suivi la chute de Z.A Ben Ali en participant à l’élection de 18 députés de l’Assemblée nationale constituante. Qu’ils soient résidents étudiants, de travail, enfants de couple mixte, exilés politiques, issus de l’exil politique et issus de l’immigration, ces acteurs « nationaux mais distants » qui représentent les « Tunisiens de l’étranger » draine une expérience sociale et politique de l’ailleurs potentiellement mobilisable dans la pratique du politique en Tunisie. L’article propose, à travers une étude rapprochée de ces députés dans l’Assemblée nationale constituante (ANC), une analyse de la circulation de normes dans la réécriture politique de la Tunisie. Le transfert de leurs expériences acquises dans un autre Etat-nation et vis-à-vis d’autres problématiques politiques et sociales agit selon un jeu de modulation et de reconfiguration face aux contraintes nationales. À travers l’étude de ces passeurs entre deux rives, leur socialisation politique et la circulation de manière de faire et de penser le politique au sein de l’arène parlementaire, nous analyserons leur hybridation et leur effet sur le processus constitutionnel. Nous verrons que l’expérience de ces députés vécue à l’étranger peut également agir en contrainte vis-à-vis des Tunisiens locaux : renvoyés à leur extranéité, les dissonances linguistiques à l’œuvre à leur « retour » illustre à propos cette tension. Ce nouvel espace circulatoire du politique remet en cause l’exclusivité nationale du politique. La migration apparait comme constitutive du national et non plus comme une excroissance de la société implantée dans l’ailleurs. Ce n’est définitivement plus par le prisme exclusif du national que peuvent être appréhendées les scènes nationales mais par des circulations qui brouillent par là même les aires culturelles traditionnelles.
La première révolution du xxie siècle ?
Authors: Benkirane Réda
Published: June 2016

En se détournant des analyses purement politiques du processus révolutionnaire, l’article propose de le lire sous l’angle philosophique des possibles ontologiques et historiques qu’il a ouvert aux peuples arabes. L’événement est pensé comme une thérapie collective susceptible, à terme, d’emporter dans son sillage les formes archaïques de l’existence, et d’assurer une sortie de la religion matérialiste et dogmatique caractérisant l’offre théologique à l’heure actuelle. Ce changement sera le fait des jeunes générations, instruites mais révoltées, qui finiront bien, d’ici dix à quinze ans, par accéder au pouvoir politique et économique dans le monde arabe, même si leur rôle politique après les révolutions a été limité par le retour de l’autoritarisme ou l’arrivée au pouvoir de l’islamisme.
L’impolitesse en interaction
Authors: Kerbrat-Orecchioni Catherine
Published: June 2016

Tout en admettant le principe général de la politesse identifiée au « travail de figuration » (face-work) préconisé et développé par Brown et Levinson, nous pensons que pour être descriptivement efficace ce modèle doit subir un certain nombre d’aménagements tels que : l’admission de la notion de Face Flattering Acts aux côtés de celle de Face Threatening Acts ; l’approfondissement de la réflexion sur les phénomènes d’impolitesse ; l’introduction dans le système de catégories venant s’ajouter à l’opposition binaire politesse/impolitesse, comme les catégories de l’« hyperpolitesse », de la « non-politesse » et de la « polirudesse ». Ces catégories ne peuvent être définies qu’en tenant compte à la fois du contenu de l’énoncé, de sa formulation, et des normes en vigueur dans la situation concernée. Elles doivent être confrontées au plus grand nombre possible d’échantillons d’interactions authentiques. Dans cette étude, les données analysées relèveront de deux types de situations d’interaction : les débats politiques télévisés et les échanges en milieu scolaire.
La fausse hiérarchisation entre information nouvelle et information ancienne à l’épreuve des modèles théoriques de la politesse
Authors: Loock Rudy
Published: June 2016

Cet article propose d’étudier la façon dont l’apport d’information nouvelle à un destinataire peut représenter un acte d’impolitesse et comment cet acte menaçant pour la face de l’autre (FTA selon le modèle de Brown & Levinson [1978], [1987]) peut être adouci par l’emploi de structures hiérarchisantes comme notamment la proposition subordonnée relative appositive ou par l’emploi d’adoucisseurs tels que you know ou as you know. Nous soulevons également les questions de la communication de l’acte de politesse lui-même, ainsi que de la conception de la politesse comme un continuum. A travers des exemples oraux attestés relevant de cette stratégie, l’objectif final de cet article est de confronter les données étudiées aux différents modèles théoriques et outils conceptuels proposés par la littérature.
Double -er suffixation in English: morphological, phonological and sociolinguistic reflections
Authors: Walker Jim
Published: June 2016

In this article, I examine a relatively little discussed phenomenon which appears to be increasingly prevalent in contemporary English, namely the reduplication of the deverbal -er suffix on phrasal verbs to produce forms such as washer upper, looker outer and asker outer. I look at some of the morphological, diachronic and sociolinguistic questions which arise, before positing the hypothesis that this reduplication is not a purely morphological phenomenon, but in fact owes a great deal to phonological causes, and in particular euphonic considerations.
Le degré de grammaticalisation de HAVE : application d’une méthodologie développée par Joan Bybee et William Pagliuca
Authors: Bordet Lucile
Published: June 2016

Cet article traite de l’évolution syntaxique, morphologique, sémantique et phonologique de HAVE. Après un bref rappel des principaux mécanismes de la grammaticalisation, et des différentes réalisations fonctionnelles de HAVE, cette étude s’efforce de déterminer le degré de grammaticalisation qu’a atteint HAVE selon ses emplois, en prenant appui sur un corpus écrit et oral. Les éléments méthodologiques qui permettent d’établir le degré de grammaticalisation ont été empruntés à J. Bybee, W. Pagliuca et R. D. Perkins [1991]. Cette étude tente de montrer dans quelle mesure les diverses réalisations phonologiques de HAVE sont révélatrices d’un degré de grammaticalisation plus ou moins avancé et comment la phonologie influence le processus.
Communication and Education Processes Involved in COPD Patient Engagement within the Italian Health System
Authors: Recchia Virginia , Dodaro Antonio , Maglie Rosita B. , Leo Carlo G.
Published: June 2016

The World Health Organization has estimated that chronic obstructive pulmonary disease (COPD) is the fourth most common cause of death worldwide. Due to the economic and social extent of the problem, patient engagement must be comprised as a new resource for the achievement of higher health outcomes and lower costs. As many key processes involved in the COPD patient engagement consist of communication and education processes, modelling those processes in a whole framework, including actors and content needs, is a requirement. The main scope of this chapter is contributing to design such a framework within the Italian Health System. Final recommendations suggest to create a synergy among patient engagement and a set of legal tools, namely informed consent, integrated care and advance care planning. The synergy is based on the fact that both patient engagement and those legal tools have a common deep root in the universal principle of patient autonomy.

The author will also discuss how research with multimedia programs reveals it can help reduce anxiety, improve knowledge, help low health literacy audiences, and contribute to improved outcomes. This chapter will also examine how multimedia decision aid programs can help patients understand their options and complex risk information, while helping them consider their values and preferences so they can truly engage in shared decision making.
Characterization of Nanostructured and Conventional TiAlN Coatings Deposited on AISI-304 Boiler Steel
Authors: Grewal Jasmaninder Singh , Sidhu Buta Singh , Prakash Satya
Published: June 2016

In the manuscript conventional and nanostructured nitrided coatings developed to increase hardness and to improve the wear, erosion and corrosion resistance of structural materials. Three coatings of TiAlN were deposited on AISI-304, out of which two were thin nanocoatings at different temperatures of 500°C and 200°C are developed by Oerlikon Balzer’s rapid coating system machine under a reactive nitrogen atmosphere. One conventional coating TiAl was deposited by Plasma spraying method which was post nitrided. Then the coated samples were characterized with relative to coating thickness, microhardness, porosity and structure. The XRD and SEM/EDAX techniques have been used to identify various phases formed after coating on the surface of steel.The microhardness of conventional TiAlN coating was found to be of the order of 900-950 Hv. The grain size for nanostructured TiAlN coatings deposited at 500°C and 200°C are 15nm and 14nm respectively as calculated by Sherrer’s formula from XRD plot.
Modeling and Analysis for Hardness and Structure of Nonferrous Alloy Castings Produced Using Zcast Metal Casting Process through Response Surface Methodology
Authors: Kumar Rajesh , Singh Rupinder , Ahuja I.P.S.
Published: June 2016

The purpose of this investigation is to develop a mathematical model for predicting the influence of casting parameters on hardness of non ferrous alloy (NFA) castings produces using Zcast process by employing response surface methodology (RSM). An association has been proposed between hardness of castings and shell wall thickness (SWT), weight density (WD) and pouring temperature (PT) of the shell mould fabricated using three dimensional printer (3DP). The experiments were conducted using NFA materials like; aluminium, zinc, lead, copper, brass and bronze. An effective procedure of RSM has been utilized for the optimal values of casting parameters. Mechanical Micro-Vickers hardness was measured in which the indent is produced by applying a known load to the specimen and then measuring the size of the appropriate diagonals optically. Based on experimental data the investigation has led to conclusion as Quadratic model have been established for predicting the response in the form of hardness of castings.Further, the model developed was validated by analysis of variance (ANOVA) which indicated the significance of model. The Model F-value of 2477.66 implies that the model is significant. There is only a 0.01% chance that a Model F-Value could occur due to noise. Values of "Prob > F" less than 0.05 indicate model terms are significant. The statistical analysis of second order quadratic equation results showed that the most significant parameters, favoring the hardness are B, C and A2. The superiority of the quadratic mathematical models were developed in confidence intervals of 99.75% with prediction error sum of squares of 3.6%for the prediction of the harness.Microstructure analysis was also performed for justification of hardness data.

Effect of Sliding Velocity on Wear Behaviour of TiAlN Coatings
Authors: Grewal Jasmaninder Singh , Sidhu Buta Singh , Prakash Satya
Published: June 2016

In the present work TiAlN coatings were deposited by plasma spray process as titanium aluminium based nitride (Ti, Al)N coatings possess excellent tribological behaviour with respect to metal cutting and polymer forming contacts. Three coatings of TiAlN were deposited on AISI-304 grade boiler steel substrate out of which two were thin nanocoatings deposited at different temperatures of 500°C and 200°C and one conventional coating was deposited by plasma spraying. The as sprayed coatings were characterized with relative to coating thickness, microhardness, porosity and microstructure. The optical microscopy (OM), the XRD analysis and field mission scanning electron microscope (FESEM with EDAX attachment) techniques have been used to identify various phases formed after coating deposited on the surface of the substrate. Subsequently the sliding wear behaviour of uncoated, PVD sprayed nanostructured thin TiAlN coatings deposited at 500°C and 200°C and plasma sprayed conventional coated AISI-304 grade boiler steel were investigated according to ASTM standard G99-03 using pin on disk wear test rig. Cumulative wear volume loss and coefficient of friction, μ were calculated for the coated as well as uncoated specimens for 0.5, 1 and 2 m/sec sliding velocities at a constant normal load of 10 N. The worn out samples were analysed with SEM/EDAX. Wear rates in terms of volumetric loss (mm3/g) for uncoated and coated alloys were compared. The nanostructured TiAlN coatings deposited at 500°C and 200°C has shown minimum wear rate as compared to conventional TiAlN coating and uncoated AISI-304 grade boiler steel. Nanostructured TiAlN coatings were found to be successful in retaining surface contact with the substrate after the wear tests.
Investigation of Penetration Rate and Surface Topography in Ultrasonic Drilling of WC-Co Composite
Authors: Kataria Ravinder , Kumar Jatinder , Pabla B.S.
Published: June 2016

WC-Co composite materials possess a vast range of industrial applications owing to their excellent properties such as superior hardness, toughness and dimensional stability. Present article has been targeted at investigating the impact of different experimental conditions (power rating, cobalt content, tool material, thickness of work piece, tool geometry, and abrasive grit size) on penetration rate in ultrasonic drilling of WC-Co composite material. Taguchi’s L-36 orthogonal array has been employed for conducting the experiments. Significant factors have been identified using analysis of variance (ANOVA) test. The experimental results revealed that power rating, abrasive grit size, and tool profile is most significant factor for penetration rate. From the microstructure analysis, the modes of material deformation have been observed and the parameters (i.e. work material properties, grit size, and power rating) were observed as the most crucial for the deformation mode.
Contamination of DNase Preparations Confounds Analysis of the Role of DNA in Alum-Adjuvanted Vaccines
Authors: Noges Laura E. , White Janice , Cambier John C. , Kappler John W. , Marrack Philippa
Published: June 2016

Aluminum salt (alum) adjuvants have been used for many years as adjuvants for human vaccines because they are safe and effective. Despite its widespread use, the means by which alum acts as an adjuvant remains poorly understood. Recently, it was shown that injected alum is rapidly coated with host chromatin within mice. Experiments suggested that the host DNA in the coating chromatin contributed to alum’s adjuvant activity. Some of the experiments used commercially purchased DNase and showed that coinjection of these DNase preparations with alum and Ag reduced the host’s immune response to the vaccine. In this study, we report that some commercial DNase preparations are contaminated with proteases. These proteases are responsible for most of the ability of DNase preparations to inhibit alum’s adjuvant activity. Nevertheless, DNase somewhat reduces responses to some Ags with alum. The effect of DNase is independent of its ability to cleave DNA, suggesting that alum improves CD4 responses to Ag via a pathway other than host DNA sensing.

Ecological preference of the diving bell spider Argyroneta aquatica in a resurgence of the Po plain (Northern Italy) (Araneae: Cybaeidae)
Authors: Mammola Stefano , Cavalcante Riccardo , Isaia Marco
Published: June 2016

The diving bell spider Argyroneta aquatica is the only known spider to conduct a wholly aquatic life. For this reason, it has been the object of an array of studies concerning different aspects of its peculiar biology such as reproductive behavior and sexual dimorphism, physiology, genetic and silk. On the other hand, besides some empirical observations, the autoecology of this spider is widely understudied. We conducted an ecological study in a resurgence located in the Po Plain (Northern Italy, Province of Vercelli) hosting a relatively rich population of Argyroneta aquatica, aiming at identifying the ecological factors driving its presence at the micro-habitat level. By means of a specific sampling methodology, we acquired distributional data of the spiders in the study area and monitored physical-chemical and habitat structure parameters at each plot. We analyzed the data through Bernoulli Generalized Linear Models (GLM). Results pointed out a significant positive effect of the presence of aquatic vegetation in the plot. In addition, the presence of A. aquatica was significantly associated with areas of the resurgence characterized at the same time by high prey availability and low density of predators. Considering the ecological importance and rarity of this species, we update and revise the data on the distribution of A. aquatica in Italy.

Coenagrion ornatum (Sélys, 1850) is a damselfly ranging from northwestern Europe to southwestern Asia. It is highly local, and northwestern populations are experiencing a steep decline. In Europe, Coenagrion ornatum is a species of conservation interest and is listed as Near Threatened due to habitat loss; it is nearly extinct in Italy. We report the finding of 4 male C. ornatum on 3 June 2005 in Apulia, southeastern Italy. This is the only recent record for Italy, and highlights the need for further research on this species in the country.
Policy issues for improving monitoring and evaluation of agricultural extension programmes in Nigeria
Authors: Matthew Akinnagbe O. , Olatunji Olaolu M.
Published: June 2016

Monitoring and evaluation are important, yet, frequently neglected functions in most organisations. In Nigeria, many programmes have been established over the years but only little monitoring and evaluation have been carried out because of many implementation problems and lack of realistic and/or stable policy framework. This paper was designed to X-ray policy issues for improving monitoring and evaluation of agricultural programmes in Nigeria. Inductive and deductive reasoning through a review of relevant literature was used in this philosophical paper. To improve the performance of agricultural extension programmes in Nigeria, the following policy issues must be addressed: The questions of what should be monitored or evaluated, when should monitoring and/or evaluation be carried out and who should monitor and/or evaluate; and the methodology to be adopted in any project should be included in any agricultural programmes and/or policies. Manpower and financial resources, effective communication and the issue of accountability must be properly considered. The tools for monitoring and evaluation are also very crucial. The paper concluded that planning a good agricultural programme is not a problem in Nigeria but poor implementation is, as a result of poor monitoring and evaluation. Therefore, attention should be on when, how and who should be involved in monitoring and evaluation.
Leadership succession patterns in the apostolic church as a template for critique of contemporary charismatic leadership succession patterns
Authors: Tushima Cephas
Published: June 2016

The pattern of leadership succession observed globally in most contemporary Pentecostal movements and churches can be characterised as dynastic succession. Yet historic modern Pentecostalism (in the Azusa tradition) prided itself on being biblical. This article explores the biblical sources, examining first the leadership structure and then the leadership succession patterns in the apostolic church as well as the extra-biblical sources of the apostolic patristic era. Our findings from this New Testament (and patristic sources) survey of leadership succession in the apostolic church and post-apostolic churches furnish a template for critical evaluation of the prevalent succession approaches of contemporary Pentecostal groups. Critical elements of apostolic and leadership structure and succession patterns are highlighted, and needed inferences are drawn for the re-shaping of leadership and its succession in contemporary Christian ministries and churches.Keywords: Azusa; Apostolic Leadership; Leadership Succession; Pentecostalism; Evangelicals; Leadership Patterns
Matthew 5:17 and Matthew's Community
Authors: Trout Bradley
Published: June 2016

One of the central arguments in establishing the ‘Christian-Jewish’ nature of the Matthean community is the argument that Matthew’s community was law observant. In particular, Matthew 5:17–19 is said to argue in favour of a community that had not broken ties with Judaism. This paper argues that Matthew 5:17–19 is not primarily about demonstrating lawobservance, but fulfilment. When πληρόω is understood in light of its broader Matthean usage, it becomes apparent that ‘to fulfil’ means the coming about of what the law and prophets anticipated. What is therefore in focus is not the conservative nature of the community, but the arrival of Israel’s hope. This is further demonstrated by the inclusion of ‘the prophets’, which also points to the coming of Jesus, as well as by the antitheses of 5:21–48, which demonstrates the Christological focus of the passage. More prominent than Jesus’ view of the law is the law’s (and prophets’) view of Jesus. An additional factor pointing in this direction is the prominence of the kingdom in this section of Matthew’s gospel. Following on from the declaration in 4:17, the kingdom of heaven remains central throughout the Sermon on the Mount, not least in 5:17–20. When this theological motif is taken into account, it confirms that 5:17–20 has in view the fulfilment of the Jewish hope that God’s kingdom would come. What God’s people have awaited – as anticipated in the law and prophets – has arrived. Reading this passage as if it were a treatise on the Matthean community’s view of the law overlooks the theological context and makes that which is peripheral (conservatism on the law) central, while what is central (fulfilment in that the kingdom has come) is made peripheral. This passage ultimately points to the newness brought about by Jesus and the kingdom of God. Scholars who find support for a conservative community in Matthew 5:17 have failed to reckon sufficiently with the nature of fulfilment in this passage.Keywords: Matthew; law; fulfilment; kingdom; community
Searching for research results to inform the design of an initial professional teacher education programme for the foundation phase: A systematic review

This article reports on a systematic review conducted to inform the development of a professional teacher education programme for the foundation phase of schooling. The research question was: What do quality research studies identify as the components and/or characteristics of quality teacher education for the foundation phase programmes that allow new teachers to begin to teach for epistemological access. A search for systematic reviews on educational programmes related to foundation phase for initial teacher education was conducted for the period between 1980 and 2011. The researchers added Stage 0 as a fifth step to the traditional four-step systematic review process. Stage 0 or quasi-tertiary review allowed us to present substantive findings of the identified systematic reviews and to explore their methodological quality. From the initial 2876 hits (mostly health and medical studies), only 19 studies were related to the educational field. Only three of the 19 studies were finally accepted as eligible at Stage 0. None of the reviews directly addressed programme design but contained elements that were considered as useful when designing programmes. The present study makes it clear that there is a dearth of research on entire programmes related to initial teacher education for foundation phase teachers. 
Problematising child-headed households:The need for children’s participation in early childhood interventions
Authors: Pillay Jace
Published: June 2016

There is insufficient literature and research that has problematised the use of the phenomenon of child-headed households (CHHs), that is, to find out if it is an acceptable term to use, if it is really a problem, and whether it needs solutions. Hence, the purpose of this study was to problematise the use of the term CHH, taking the theories of Freire and Foucault into consideration. This generic qualitative study consisted of a sample of 16 experts who worked with children from CHH. Data were collected through a questionnaire and individual telephonic interviews with the experts identified. The findings indicate that, for several reasons, the current use of the term CHH is acceptable and is a problem that has to be taken seriously by the relevant stakeholders. In light of the findings, the author emphasises the importance of recognising the capacity of children from CHH to actively participate in early childhood interventions geared to improve their social environments.

Does a physiotherapy programme of gross motor training influence motor function and activities of daily living in children presenting with developmental coordination disorder?
Authors: Maharaj Sonill S. , Lallie Riona
Published: June 2016

Background: Children with developmental coordination disorder (DCD) lack motor coordination and have difficulty performing motor skills and activities of daily living. Research shows these children do not outgrow their motor difficulties and without intervention do not improve. Physiotherapy is relevant for these children, but due to limited clinical protocols for DCD the aim of this study was to determine the effect of a gross motor training programme for 6–12-year-old children with DCD.Methods: This randomised pre-test, post-test study recruited 64 children with scores of 15th percentile or below using the Movement Assessment Battery for Children (M-ABC). The children were divided equally into an intervention group receiving 8 weeks of gross motor training for core stability, strengthening exercises, balance and coordination with task-specific activities for 30 min per week, while the control group continued with general therapy and activities of daily living. The M-ABC and Developmental Coordination Disorder Questionnaire (DCDQ) were used to assess each child before and after 8 weeks.Results: Sixty children completed the study, with 43 males and 17 females (mean age 10.02 years, SD = 2.10). There were no adverse reactions to the programme and M-ABC scores for the intervention programme improved by 6.46%, ball skills (3.54%) and balance (4.80%) compared with the control (0.17%) and (0.15%), respectively. There were significant (p < 0.05) improvements in DCDQ scores, but teachers allocated lower scores than parents.Conclusion: This study supports 8 weeks of gross motor training which can be a beneficial intervention for physiotherapists to improve gross motor function for DCD.Keywords: Developmental, co-ordination, skills, motor

Published: June 2016

Lipomas and lipoblastomas are benign tumors of mesenchymal origin in contrast to liposarcoma that is a malignant tumor. Atypical lipomatous lesion arising from embryonal fat cells is termed as lipoblastoma. In the present case report 9-month-old male presented to us with painless, rapidly progressing mass over back, power was normal in all four limbs, fine needle aspiration cytology was suggestive of cellular tissue, magnetic resonance imaging suggestive of well-defined enhancing mass in paravertebral location, extending from D3 to D10 vertebrae with intraspinal extension, communicating through neural foramina at level of D7. Intraoperatively, it was dumbbell-shaped, looked like neurofiboma based on the gross findings and it was adherent to dorsal nerve root also. Single level laminectomy with complete surgical excision of lesion done with sacrifice of dorsal nerve root. Histopathology was suggestive of lipoblastoma. Postoperative recovery was uneventful.
Isolated extracranial intraosseous metastasis of an intracranial meningioma following bevacizumab therapy: Case report and review of the literature
Authors: Mukherjee Debraj , Hu Jethro , Chu Ray
Published: June 2016

Meningiomas account for a significant proportion of all primary intracranial tumors; distant metastasis is quite rare. We report a patient with resected, atypical meningioma. The patient's clinical course over 5 years included two craniotomies, a course of radiation, and a shortened course of bevacizumab. Only 5 months after starting bevacizumab, the patient developed an isolated left clavicular pathological fracture attributable to metastatic anaplastic meningioma. This constitutes the first report of meningioma with isolated extracranial intraosseous metastasis in the modern English literature and highlights concerns associated with the use of anti-angiogenic agents in promoting more invasive tumor phenotypes upon disease recurrence.
