Penser la psychanalyse avec le jazz
Authors: Vinot Frédéric
Published: February 2016

L’auteur propose de concevoir la psychanalyse et le jazz comme des pratiques de l’improvisation qui peuvent entrer en dialogue. Deux points de rapprochement entre ces pratiques sont particulièrement explorés : l’aliénation/séparation que comporte toute improvisation, et la dimension performative de la résonance sur laquelle l’enseignement de Lacan s’est interrompu.
De l’improvisation maternelle
Authors: Vivès Jean-Michel
Published: February 2016

L’auteur de l’article s’attache à mettre en évidence la place et le rôle de l’improvisation maternelle dans la relation mère/bébé ainsi que dans l’émergence du sujet. Il propose de distinguer trois temps qui seraient associés à l’improvisation maternelle : – le premier serait dominé par la supposition. La mère suppose chez le bébé des capacités, des intentions bien avant que celles-ci ne soient présentes chez lui. Même si elles ne sont pas encore présentes, d’être supposées ces capacités et intentions sont potentialisées. Il s’agit là, pourrait-on dire, d’un pur acte de croyance qui ne nécessite pas de s’exprimer en vocalisations ou en mots ; – un autre temps s’exprimerait lui par un partenariat essentiel avec le bébé : plus qu’une dyade, mère et bébé constituent un véritable duo. Bébé et mère sont des partenaires à parts égales et coconstruisent une œuvre aux dimensions musicales indéniables où rythme et mélodie jouent un rôle essentiel. Ce temps est le temps de l’œuvre commune ; – enfin, un dernier temps verrait la mère s’adresser au bébé en privilégiant le langage par rapport à la vocalisation. Ce qu’elle fait préférentiellement sur le mode du questionnement où une place à venir est indiquée à l’enfant. Celui-ci ne peut encore parler mais l’environnement maternel fait l’hypothèse que cette place qu’il dessine sera un jour occupée d’où jaillira un « je ».
Réflexions sur la parole : entre le rire et l’ennui
Authors: Bidaud Éric
Published: February 2016

Il est tout aussi impossible d’échapper à l’ordre du langage qu’il l’est de ne pas lui échapper. Failles, trébuchements constituent l’imprévu de la parole et fabriquent la matière et l’espace indéfinis de la démarche analytique. Ce travail propose une réflexion sur la parole analytique en lien avec deux champs « ordinaires » de l’état psychique du sujet : le rire et l’ennui. La question de l’amour de transfert ici posée tente de trouver une nouvelle manière de se traduire au travers de la prise en compte d’un cri ordinaire : le rire, et d’un certain appel au silence comme condition de ce qui s’improvise de la création du sujet : l’ennui.
Rythm’in’séance…

« L’imprévu, c’est avec cela que l’analyste travaille au quotidien. » À partir de cette proposition, nous tentons de penser ce qui arrive dans l’espace des séances. Ce qui arrive est souvent inouï, nous sommes sur-pris par le jeu des mots qui s’assemblent de manière inédite. Ils parlent ensemble de manière inédite car ils jouent ensemble avec les mots au seuil du langage dans ce décalage nécessaire, ce ralenti au milieu de l’agitation urbaine. Un lieu pour rêver/créer avec les rêves de la nuit et du jour, pour saisir au vol les mots comme autant de points lumineux éclairant le chemin. Ils jouent ensemble à créer des formes dans le mouvement d’un va-et-vient psychique, plaisir hallucinatoire des mots, à jouer librement avec les mots comme l’enfant s’en saisit, les assemble dans la recherche du plaisir au rythme de la langue. Un mot pour un autre qui éclaire la voie libre laissant entrevoir les pensées dissimulées. Ni l’analysant ni l’analyste ne savent comment les notes vont porter et se reporter sur la partition, aucun des deux ne sait au préalable quelle en sera la musique…
Entre S. Freud et P. Federn : la culture en partage
Authors: Houssier Florian , Blanc Adrien , Bonnichon Delphine , Vlachopoulou Xanthie
Published: February 2016

L’intérêt voire la passion de Freud pour la culture dans ses aspects les plus divers sont, de nos jours, assez connus. Pour autant, à travers la correspondance entre S. Freud et P. Federn, composée de 147 cartes et lettres, dont certaines totalement inédites, nous proposons de faire émerger la qualité de leur lien à partir de leur intérêt commun pour la culture. Davantage qu’un collègue, Federn fut à la fois le bras droit de Freud sur le plan institutionnel à Vienne, ainsi que la personne de confiance à laquelle il adressa une partie de ses patients. Outre l’intérêt historique offert par cette correspondance, ces lettres font remonter à la surface des tensions autour d’investigations théoriques qui, d’hier à aujourd’hui, continuent de traverser la psychanalyse.
Le livret de vie , un outil thérapeutique narratif pour l’enfant victime de maltraitance intrafamiliale
Authors: Traoré Mariame
Published: February 2016

La maltraitance peut figer la victime dans un monde sans symbolisation dans lequel le trauma se répète inlassablement. L’auteur formalise un outil thérapeutique (inspiré des approches narratives), qui permet de sortir de cet engrenage pour les enfants victimisés au sein de leur famille, mais aussi pour tous patients ayant vécu des traumas de divers ordres et de diverses intensités. Après avoir posé les bases théoriques qui ont été nécessaires à l’élaboration du livret de vie , l’outil est présenté et illustré à l’aide de deux vignettes cliniques.
Pupil Influence on the Visual Outcomes of a New-Generation Multifocal Toric Intraocular Lens With a Surface-Embedded Near Segment
Authors: Wang Mengmeng , Corpuz Christine Carole C. , Huseynova Tukezban , Tomita Minoru
Published: February 2016

PURPOSE:

To evaluate the influences of preoperative pupil parameters on the visual outcomes of a new-generation multifocal toric intraocular lens (IOL) model with a surface-embedded near segment.

METHODS:

In this prospective study, patients with cataract had phacoemulsification and implantation of Lentis Mplus toric LU-313 30TY IOLs (Oculentis GmbH, Berlin, Germany). The visual and optical outcomes were measured and compared preoperatively and postoperatively. The correlations between preoperative pupil parameters (diameter and decentration) and 3-month postoperative visual outcomes were evaluated using the Spearman's rank-order correlation coefficient (

R
s

) for the nonparametric data.

RESULTS:

A total of 27 eyes (16 patients) were enrolled into the current study. Statistically significant improvements in visual and refractive performances were found after the implantation of Lentis Mplus toric LU-313 30TY IOLs (
P
< .05). Statistically significant correlations were present between preoperative pupil diameters and postoperative visual acuities (

R
s

> 0;
P
< .05). Patients with a larger pupil always have better postoperative visual acuities. Meanwhile, there was no statistically significant correlation between pupil decentration and visual acuities (
P
> .05).

CONCLUSIONS:

Lentis Mplus toric LU-313 30TY IOLs provided excellent visual and optical performances during the 3-month follow-up. The preoperative pupil size is an important parameter when this toric multifocal IOL model is contemplated for surgery.

Trabajo, independencia y subordinación. La regulación del trabajo autónomo en España
Authors: Riesco-Sanz Alberto
Published: February 2016

Este artículo presenta y contextualiza el ambicioso marco regulador y protector del Estatuto del Trabajo Autónomo vigente en España desde 2007. Junto al análisis de su novedad y alcance, el artículo se interroga sobre el sentido de una reforma considerada paradójica. Por un lado, porque supone la organización y regulación del trabajo autónomo bajo un estatuto de empleo específico que, sin embargo, no ha hecho sino aproximarse al estatuto del trabajo asalariado (reduciendo más que ampliando la distancia que históricamente les separaba). Por otro lado, porque esta reforma tiene lugar en un momento en el que, tendencialmente, el empleo autónomo –que históricamente ha ocupado un lugar destacado en España– se encuentra en retroceso. Más que disociar el trabajo autónomo del trabajo asalariado, el artículo nos invita a explorar la relación existente entre ambas formas de trabajo, considerando al trabajo autónomo no como la negación del salariado, sino como testigo de su potencia al tiempo que de su profunda transformación.
Rejet expéditif par la CEDH de la requête d’un étranger malade en voie d’expulsion : Une Convention à deux vitesses ?
Authors: Klausser Nicolas
Published: February 2016

Par une décision du 12 novembre 2015 rendue en Comité de trois juges, la Cour européenne des droits de l’homme (CEDH) a rejeté la requête présentée le 12 août 2015 par un ressortissant arménien à l’encontre de la mesure d’éloignement du territoire français dont il fait l’objet, édicté par la préfecture de la Côte d’Or. Ce dernier avait fait valoir un risque de violation de l’article 3 de la Convention européenne des droits de l’homme (CESDH), car il ne pourrait avoir accès aux soins nécessaires à son état de santé en Arménie, comme l’a estimé le médecin de l’Agence régionale de santé (MARS) du Rhône dans son avis. La Cour a d’abord indiqué au gouvernement français, conformément à l’article 39 de son règlement, « qu’il était souhaitable de ne pas expulser le requérant vers l’Arménie pour la durée de la procédure devant la Cour ». Il lui a également demandé d’exposer les garanties dont il dispose « pour s’assurer que le requérant sera pris en charge par les autorités médicales locales en cas de renvoi vers l’Arménie ». Au regard des éléments avancés par le gouvernement français, la Cour européenne a levé la mesure provisoire, puis a déclaré la requête irrecevable en jugeant suffisantes les preuves de la disponibilité des soins. Pourtant, l’évaluation de la disponibilité des soins ainsi que la motivation de la Cour sont quelque peu lacunaires, et emportent diverses conséquences néfastes pour les étrangers malades faisant l’objet d’une mesure d’éloignement.
Virtual Design Teams in Virtual Worlds
Authors: Rive Pete B.
Published: February 2016

Design innovation increasingly requires cross-functional virtual teams and is becoming plural, collaborative and distributed. In order for global companies to compete they must be able to sync with the rapidly increasing pace of change and be able to tap the international talent that may, in the future, only connect via virtual worlds and virtual reality. It is important to recognise how design innovation and knowledge flow are regulated and how the virtual ecosystem can either inhibit or excite collaboration and the creation of new ideas, and the design of useful prototypes. This chapter presents a theoretical framework using three models, with examples, to explain and understand how virtual design teams can identify the regulation of knowledge flow and collaboration in the virtual world, Second Life.
The World is your Office
Authors: Chamakiotis Petros , Panteli Niki
Published: February 2016

Despite the increasing adoption of global virtual teams in industry, and their implications for traditional management practices, creativity within this context has been under-researched, with most studies focusing on students partaking in contrived virtual team projects in educational environments. This chapter focuses on a global virtual organization, Omega (a pseudonym), with the aim of exploring creativity in an organizational virtual team context. Using a qualitative case study approach in a single organization, the study makes the following contributions: (a) it identifies the personal values that motivate creativity; and (b) it explains how individuals, technology, task and organization influence creativity, drawing on the participants' perceptions. Discussed also in the chapter are implications for practice and future research.
Policy Making
Authors: Gholipour Rahmatollah
Published: February 2016

Policy making is a tool for modern societies to manage an array of public issues including health. At first, the concept and content of policy making will be described in this chapter. In order to do so, first the science of policy making and its history and objectives have been expressed and it is concluded that this science as a branch of political and administrative sciences considers the study of policies and certain functions of government in different fields. Then the concept of policy making and public policy are discussed. Since the current economic, social conditions and political values, government structure and cultural norms affect public policy making, the contexts of public policy making have been reviewed briefly. After that a variety of public policy, qualities of a good policy and the key factors in public policy making and rationality has been reviewed. In this chapter, in fact, the health policy will be studied as one of the crucial issues in this era and its dimensions will be discussed.
Bridging the Gaps with Nonprofits
Authors: Caccioppoli Laura
Published: February 2016

This chapter will examine how nonprofits are both bridging the gaps left behind from health policy, and are at the intersection of institutions, interests, and the policy process. Using cultural competency as a theoretical lens, the chapter will make use of the current literature, demographic trends, and other qualitative and quantitative data to situate three case studies. As the Affordable Care Act, and other health policies tout themselves as solutions to gaps in health care services for minorities, this chapter offers an overview and evaluation of these policies as well as an explanation of the role nonprofits have in filling necessary service delivery and advocacy.
IL-1 Receptor Signaling on Graft Parenchymal Cells Regulates Memory and De Novo Donor-Reactive CD8 T Cell Responses to Cardiac Allografts

Published: February 2016

Reperfusion of organ allografts induces a potent inflammatory response that directs rapid memory T cell, neutrophil, and macrophage graft infiltration and their activation to express functions mediating graft tissue injury. The role of cardiac allograft IL-1 receptor (IL-1R) signaling in this early inflammation and the downstream primary alloimmune response was investigated. When compared with complete MHC-mismatched wild-type cardiac allografts, IL-1R−/− allografts had marked decreases in endogenous memory CD8 T cell and neutrophil infiltration and expression of proinflammatory mediators at early times after transplant, whereas endogenous memory CD4 T cell and macrophage infiltration was not decreased. IL-1R−/− allograft recipients also had marked decreases in de novo donor-reactive CD8, but not CD4, T cell development to IFN-γ–producing cells. CD8 T cell–mediated rejection of IL-1R−/− cardiac allografts took 3 wk longer than wild-type allografts. Cardiac allografts from reciprocal bone marrow reconstituted IL-1R−/−/wild-type chimeric donors indicated that IL-1R signaling on graft nonhematopoietic-derived, but not bone marrow–derived, cells is required for the potent donor-reactive memory and primary CD8 T cell alloimmune responses observed in response to wild-type allografts. These studies implicate IL-1R–mediated signals by allograft parenchymal cells in generating the stimuli-provoking development and elicitation of optimal alloimmune responses to the grafts.

Published: February 2016

Proline is one of amino acid that usually accumulates inside the plant cell when facing drought stress. The accumulation of proline can protect the plant cell from damage during drought. The aim of this research was to determine proline content and yield components of local corn cultivars from Kisar Island, Maluku, Indonesia. The field trial was organized using randomized block design with three replicates. Six local corn cultivars found in Kisar Island (Deep Yellow, Early Maturing Yellow, Red Blood, Rubby Brown Cob, Waxy, and White) were used as plant materials and a recommended tolerance variety (Srikandi) was taken as reference group. Proline content was determined using ninhydrin method. Yield components variables included cob weight (at harvest, after air dry, after oven dried, at 12% of water content), cob water content at harvest, cob length, cob diameter, number of seed row per cob, number of seed per cob, and cob yield at 12% of water content. Data collected was analysed with analysis of variance followed by Duncan multiple range test at the significant level 0.05 using Statistical Analysis System/SAS software version 9.0. The result shows that highest proline content and yield components (except for cob water content) was showed by the Deep Yellow cultivar. The lowest proline content was showed by Rubby Brown Cob cultivar. The lowest corn yield components was showed by Red Blood local cultivar. Deep Yellow cultivar can be proposed as superior drought tolerance variety, and can be recommended for further wide cultivation in Maluku province.
Erasmus syndrome in a marble worker

Published: February 2016

Erasmus syndrome is defined as the association of silica exposure and subsequent development of systemic sclerosis. The limited number of cases reported in the literature mainly involves miners and only sporadically other professionals. We describe a case of Erasmus syndrome in a marble worker. A 68 year old man came to our observation complaining pelvic and scapular girdle pain, evening fever, intense weakness and emaciation for about 1 month. He also reported to have had Raynaud’s phenomenon in his hands for the last 13 years. Also, his occupational history revealed a chronic exposure to silica dust. The patient presented pain in his shoulders and hips, moderate skin thickening and sclerosis in his hands and fingers extending proximally to his wrists. The diagnosis of systemic sclerosis was determined according to his clinical and medical history, the positivity of anti-Scl 70 antibodies, the nailfold capillaroscopy suggestive of an active scleroderma pattern and the detection of a mild restrictive pulmonary syndrome. The evaluation of the organbased complications excluded a gastroenterological and cardiovascular involvement, while the chest computed tomography (CT) detected multiple small nodules with a mantle distribution and enlarged lymph nodes with no signs of interstitial lung disease and fibrosis. Additional tests (positron emission tomography-CT, flexible bronchoscopy and broncho-alveolar lavage) excluded infectious diseases and cancer. However, given the pulmonary involvement, we performed a histological examination of the parenchyma and lymph nodes, which revealed a picture of pneumoconiosis. In the end, the occupational history and the findings from the diagnostic procedures led to the diagnosis of pulmonary silicosis. The precise definition of the pulmonary involvement was essential to the therapeutic approach to this patient.
Neutrophil-lymphocyte ratio, pain perception, and disease activity score may serve as important predictive markers for sustained remission in rheumatoid arthritis
Authors: Chandrashekara S. , Rajendran A. , Bai Jaganath A. , Krishnamurthy R.
Published: February 2016

The implementation of new treatment strategies based on current recommendations has enabled a greater number of patients with rheumatoid arthritis (RA) to achieve remission. However, there are no definite predictors of sustained remission. Moreover, the absence of clear consensus on the time of withdrawal or reduction of treatment further adds to the treatment burden. This pilot study was intended to evaluate the prognostic potential of various RA-related parameters. All the enrolled subjects (n=124) were clinically evaluated on the basis of various parameters including age, gender, duration of illness before the initiation of disease-modifying anti-rheumatic drugs, tender and swollen joints (28 joints), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), hemoglobin percentage, lymphocyte count, total white-blood cell counts, and neutrophil to lymphocyte ratio (NLR). Student’s t-test and discriminant function analysis were performed. The specificity of all parameters and their best possible cut-off to predict relapse were calculated using the receiver operating characteristic (ROC) analysis. A significant difference in terms of pain perception, NLR, tendency to have a significant tender joint count and absolute lymphocyte counts was identified between the patients in sustained remission and those in relapse. The ROC analysis indicated that NLR was consistent in predicting remission. CRP, ESR, and/or disease activity score may not be very effective in differentiating patients with sustainable remission/low disease activity. NLR along with patient’s perception of pain may assist in predicting sustained remission.
Yet another $p$-adic hyperbolic disc: Hilbert distance for $p$-adic fields
Authors: Guilloux Antonin
Published: February 2016

We describe in this paper a geometric construction in the projective

p

-adic plane that gives, together with a suitable notion of

p

-adic convexity, some open subsets of

\mathbf P_2(\mathbf Q_p)

naturally endowed with a "Hilbert" distance and a transitive action of PGL(2,

\mathbf Q_p)

by isometries. These open sets are natural analogues of the hyperbolic disc, more precisely of Klein's projective model. But, unlike the real case, there is not only one such hyperbolic disc. Indeed, we find three of them if

p

is odd (and seven if

p=2

).

Let us stress out that neither the usual notion of convexity nor that of connectedness as known for the real case are meaningful in the

p

-adic case. Thus, there will be a rephrasing game for the definitions of real convexity until we reach a formulation suitable for other local fields. It will lead us to a definition of

p

-adic convexity by duality. Although we will not recover the beautiful behaviour of real convexity, we will still be able to define the most important tool for our goals, namely the Hilbert distance.

We construct our analogues of the hyperbolic disc (once again, via the projective model of the hyperbolic plane) in a quite geometric, even naive, way. Our construction gives

2

-dimensional objects over

\mathbf Q_p

. It is very different, in spirit and in facts, of Drinfeld

p

-adic hyperbolic plane [1]. The possible relations between the two objects remain still unexplored. Another object often viewed as an analogue of the hyperbolic disc is the tree of PGL(2,

\mathbf Q_p)

[8]. We explore the relations between our discs and this tree, constructing a natural quasi-isometric projection from the discs to the tree. Eventually we explore the transformation groups of our discs. And, whereas the transformation group of the tree is huge, we prove that only PGL(2,

\mathbf Q_p)

acts on the discs preserving the convex structure.
Integrable measure equivalence for groups of polynomial growth
Authors: Austin Tim
Published: February 2016

Bader, Furman and Sauer have recently introduced the notion of integrable measure equivalence for nitely-generated groups. is is the sub-equivalence relation of measure equivalence obtained by insisting that the relevant cocycles satisfy an integrability condition. They have used it to prove new classication results for hyperbolic groups. The present work shows that groups of polynomial growth are also quite rigid under integrable measure equivalence, in that if two such groups are equivalent then they must have bi-Lipschitz asymptotic cones. This will follow by proving that the cocycles arising from an integrable measure equivalence converge under re-scaling, albeit in a very weak sense, to bi-Lipschitz maps of asymptotic cones.

The conjugacy problem in groups of non-orientable 3-manifolds
Authors: Préaux Jean-Philippe
Published: February 2016

We prove that fundamental groups of non-orientable 3-manifolds have a solvable conjugacy problem and construct an algorithm. Together with our earlier work on the conjugacy problem in groups of orientable geometrisable 3-manifolds, all 1 of (geometrisable) 3-manifolds have a solvable conjugacy problem. As corollaries, both the twisted conjugacy problem in closed surface groups and the conjugacy problem in closed surface-by-cyclic groups, are solvable.

Published: February 2016

Cutaneous leishmaniasis is a very complex disease involving multiple factors that limit its emergence and spatial distribution. Prediction of cutaneous leishmaniasis epidemics in Tunisia remains difficult because most of the epidemiological tools used so far are descriptive in nature and mainly focus on a time dimension. The purpose of this work is to predict the potential geographic distribution of Phlebotomus papatasi and zoonotic cutaneous leishmaniasis caused by Leishmania major in Tunisia using Grinnellian ecological niche modeling. We attempted to assess the importance of environmental factors influencing the potential distribution of P. papatasi and cutaneous leishmaniasis caused by L. major. Vectors were trapped in central Tunisia during the transmission season using CDC light traps (John W. Hock Co., Gainesville, FL). A global positioning system was used to record the geographical coordinates of vector occurrence points and households tested positive for cutaneous leishmaniasis caused by L. major. Nine environmental layers were used as predictor variables to model the P. papatasi geographical distribution and five variables were used to model the L. major potential distribution. Ecological niche modeling was used to relate known species' occurrence points to values of environmental factors for these same points to predict the presence of the species in unsampled regions based on the value of the predictor variables. Rainfall and temperature contributed the most as predictors for sand flies and human case distributions. Ecological niche modeling anticipated the current distribution of P. papatasi with the highest suitability for species occurrence in the central and southeastern part of Tunisian. Furthermore, our study demonstrated that governorates of Gafsa, Sidi Bouzid, and Kairouan are at highest epidemic risk.
Phylogenetic Analysis of Chikungunya Virus Strains Circulating in the Western Hemisphere
Authors: Lanciotti Robert S. , Lambert Amy J.
Published: February 2016

In December 2013, chikungunya virus (CHIKV) was isolated for the first time in the Western Hemisphere (WH) during an epidemic on the island of St. Martin. Subsequently, the virus has spread to 42 countries or territories in the Caribbean, Central, South, and North America. In this study, we have determined the full genomic sequences of 29 temporally and geographically diverse CHIKV strains from 16 countries of the WH. Phylogenetic analyses revealed minimal evolution among compared emergent CHIKV strains of the New World.
Limited Degradation of the Plasmodium falciparum Gametocyte Marker pfs25 mRNA Exposed to Tropical Temperatures: Considerations for Malaria Transmission Field Studies
Authors: Waltmann Andreea , Karl Stephan , Chiu Chris , Mueller Ivo
Published: February 2016

An important aspect of many malaria molecular epidemiology and transmission studies is RNA-based detection of gametocytes. Ensuring RNA stability represents a challenge in tropical, resource-limited environments, as RNA may quickly degrade when samples are not preserved under adequate conditions. This study investigated the degradation of pfs25 messenger RNA (mRNA), the most widely used Plasmodium falciparum gametocyte marker, in whole blood spiked with cultured P. falciparum gametocytes, exposed to different temperatures for up to 48 hours, and collected with different anticoagulants. The levels of pfs25 mRNA were similar between samples stored at 4°C and 30°C for up to 48 hours before stabilization with RNAprotect (Qiagen, Hilden, Germany). We observed that pfs25 mRNA in heparin-collected blood degraded less than that in ethylenediaminetetraacetic acid (EDTA)–collected blood over the 48-hour period. For field studies aiming for P. falciparum gametocyte detection, immediate stabilization of blood samples is not necessary, as the pfs25 transcript is relatively stable, more so in heparin than EDTA collection tubes.
Transcript Abundance of Putative Lipid Phosphate Phosphatases During Development of Trypanosoma brucei in the Tsetse Fly
Authors: Alves e Silva Thiago Luiz , Savage Amy F. , Aksoy Serap
Published: February 2016

African trypanosomes (Trypanosoma brucei spp.) cause devastating diseases in sub-Saharan Africa. Trypanosomes differentiate repeatedly during development in tsetse flies before gaining mammalian infectivity in fly salivary glands. Lipid phosphate phosphatases (LPPs) are involved in diverse biological processes, such as cell differentiation and cell migration. Gene sequences encoding two putative T. brucei LPP proteins were used to search the T. brucei genome, revealing two additional putative family members. Putative structural features and transcript abundance during parasite development in tsetse fly were characterized. Three of the four LPP proteins are predicted to have six transmembrane domains, while the fourth shows only one. Semiquantitative gene expression revealed differential regulation of LPPs during parasite development. Transcript abundance for three of the four putative LPP genes was elevated in parasites infecting salivary glands, but not mammalian-infective metacyclic cells in fly saliva, indicating a potential role of this family in parasite establishment in tsetse salivary glands.
Rapidly Progressing Chagas Cardiomyopathy
Authors: Hollowed John , McCullough Matthew , Sanchez Daniel , Traina Mahmoud , Hernandez Salvador , Murillo Efrain
Published: February 2016

Chagas disease, caused by the parasite Trypanosoma cruzi, can cause a potentially life-threatening cardiomyopathy in approximately 10–40% of afflicted individuals. The decline in cardiac function characteristically progresses over the course of many years. We report a case of Chagas disease in which the patient experienced an atypical rapid deterioration to severe cardiomyopathy over the course of 16 months. This case argues the need for increased routine surveillance for patients with confirmed T. cruzi infection, who are determined to be at high-risk for worsening cardiomyopathy.
The Effect of Temperature on Wolbachia-Mediated Dengue Virus Blocking in Aedes aegypti
Authors: Ye Yixin H. , Carrasco Alison M. , Dong Yi , Sgrò Carla M. , McGraw Elizabeth A.
Published: February 2016

Dengue fever, caused by dengue virus (DENV), is endemic in more than 100 countries. The lack of effective treatment of patients and the suboptimal efficacies of the tetravalent vaccine in trials highlight the urgent need to develop alternative strategies to lessen the burden of dengue fever. Wolbachia pipientis, an obligate intracellular bacterium, is being developed as a biocontrol strategy against dengue because it limits the replication of the DENV in the mosquito vector, Aedes aegypti. However, several recent studies have demonstrated the sensitivity of pathogens, vectors, and their symbionts to temperature. To understand how the tripartite interactions between the mosquito, DENV, and Wolbachia may change under different temperature regimes, we assessed the vector competence and transmission potential of DENV-infected mosquitoes reared at a common laboratory setting of a constant 25°C and at two diurnal temperature settings with mean of 25°C and 28°C and a fluctuating range of 8°C (±4°C). Temperature significantly affected DENV infection rate in the mosquitoes. Furthermore, temperature significantly influenced the proportion of mosquitoes that achieved transmission potential as measured by the presence of virus in the saliva. Regardless of the temperature regimes, Wolbachia significantly and efficiently reduced the proportion of mosquitoes achieving infection and transmission potential across all the temperature regimes studied. This work reinforces the robustness of the Wolbachia biocontrol strategy to field conditions in Cairns, Australia, and suggests that similar studies are required for local mosquito genotypes and field relevant temperatures for emerging field release sites globally.

Out- of- home advertising transcends time. Today, it covers broad spectrum of referencing. The medium dates back to over 5000 years ago when the Egyptians used obelisk as directional sign for travellers. Subsistent economy in the South East and part of South-South geographical zone of Nigeria used the yam barn as attention getting device as well as storage system. Conventional outdoor platform came into existence in Nigeria since 1929, but from 1980s, optional site specifics were located in vintage positions in form of Installations. The 3D sculptural art form as a reminder medium, positions popular brands such as Star lager beer, Guinness and Milo beverage. Dictates of globalization experienced in Integrated Marketing Communication (IMC) now uses installation as movable promotional medium seen in Triple.X Historical and analytical methods in addition to advertising theory espoused by Edward Meyer were used to position findings. By implication, advertising theory, practice and postulations worked to facilitate s transition since 1980s onto the globalization today. Triple.X promotional outing positions Nigeria’s practice in time and space but lags behind the level of practice in advanced countries where diverse method of out- of- home designs are in competitive mode.Keywords: Out- of – home.

A Great Igbo Liturgical Music Composer: The Lives and Works of Very Rev. Msgr. Cyril Ezenduka
Authors: Nwobu Stella Nkiruka
Published: February 2016

The Catholics deem that he who sings once prays twice. To Very Rev. Msgr. Ezenduka (Late), it was he who sings well and meaningfully. As a great Igbo liturgical music composer, he composed over; eighty liturgical music colossally, for Catholics throughout the Igbo speaking dioceses of Nigeria, through which the devout lives of millions of people were transformed. The Vatican II (1962 1965) which carried enormous modifications in Divine Worship, including the sacred music concurred with Msgr. Ezenduka's priestly ordination in 1964. Consequently, he devoted his pastoral ministry to explore practical ways to contextualize and implement the conciliare declarations. This work is significant because it will expose his personality and showcases his original compositions which demonstrated how Igbo tonality, sensibility and rhythm could virtuously express the spirit of the liturgy and even enrich it as disparate to Igbo hymns that were adapted to western metrical tunes, while not respecting the native Igbo tonality, affronted the language.
Reading of Waiting, Time and Social Change in S. N. A. Agoro’s Something To Die For
Authors: Binebai Benedict , Ineritei Kingsley I.
Published: February 2016

The study of waiting and time, hope and none fulfilment of hope, came into literary limelight in literature particularly in the dramas of Samuel Beckett, the absurdist playwright and others like Albert Camus, Martin Esslin and Eugene Ionesco. The subject is most prominent in Samuel Beckett’s seminal dramas - Waiting for Godot (1956) and End Game (1957). In these dramas waiting is presented as a static experience that generates the rise and fall of hope. It breeds frustration, alienation, faithlessness and depersonalization. The act of waiting as a critical feature of the human condition is the most significant and intense thematic engagement in Beckett’s Waiting for Godot. The study notes that aside the circle of the absurd art in drama, the subject of waiting and time has not been given adequate dramatic representation by dramatists outside the absurd background. It is against this backdrop that we attempt to explore the depiction and treatment of waiting, time and social change in the dramatic universe of existentialism created by some playwrights who have not been given scholarly attention. The study shall therefore undertake a dialectical consideration of the concept of waiting and time in Agoro’s Something to die Foran existential drama and raise new judgment in the appreciation of waiting and time from the perception of Christian reflection in literary limelight and scholarship.Keywords: dialectics, waiting and time, social change, absurdism, existentialism
Nigeria at 100, 1914-2014: Alternative Projections for the Next 100 Years
Authors: Ugbeda Ejura C.M , Egwemi Victor
Published: February 2016

This paper is an examination of the first 100 years of Nigeria between 1914 and 2014. It traces the history of the country from the 1851 attack on Lagos and examines the series of events leading up to the 1914 amalgamation. It argues that the first 100 years have been a mixed bag of good and bad. At the risk of passing judgment on which of the two has surpassed the other, the paper avers that the very fact of the country’s continued existence tells a lot whatever the sentiments may be. In the last 100 years Nigeria has been confronted with many challenges; a lack of unity, a largely dependent socio-economic structure, a culture of corruption and impunity, terrorism and insurgency and poverty among other negative features. The paper comes up with alternative projections for the next 100 years namely, developing and nurturing a culture of oneness, diversifying the economy and dealing decisively with the problems of corruption, poverty and insurgency. The paper advocates among other things that government must muster the necessary political will to make the difficult decisions that will take the country from potential to actualgreatness. The people on their part must make the necessary sacrifices to bring this aboutKeywords: Amalgamation, Colonialism, Alternative Projections, 1914-2014, Nigeria
Reflections on Architecture Design Education: The Integrated Design Paradigm
Authors: Bashier Fathi
Published: February 2016

Studies have recently discussed the failure of traditional design in the studio to develop a rational approach based on systematic methods and objective knowledge. They agree that such an approach is incompatible with the complexity of modern design problems and recognize the need to replace it with a disciplinary approach in order to meet the challenges of modern design. Most critics attribute the failure of the traditional approach to the lack of knowledge. This study, however, argues that the problem is more precisely a problem of the inadequacy of design knowledge conception, and suggests that the development of a discipline-based approach cannot be achieved unless the entire knowledge conception is properly understood and theorized. To achieve this end the study has introduced, in a previous article, the integrated design paradigm as a theoretical framework which describes the knowledge system within the design process. In this article the study reviews the integrated design paradigm and develops a new understanding of design knowledge conception based on systems theory. In the light of this holistic perception, the study proposes the design process systems approach, a disciplinary model based on the integrated conception of design knowledge. However, both ‘the design process systems model’ and ‘the (revised)  integrated design paradigm’ upon which it is based will have to be empirically verified in a future article.Keywords: process, knowledge, systems theory, knowledge conception, process systems
Understanding the Characteristics of Adaptability and Multi-functionality in Buildings of the Future
Authors: Daniel Etteh Ania
Published: February 2016

Communities and their various housing needs change over time, hence they require spaces that can adapt well to those changes and even allow for a range of users to enjoy the same space at different times. This research was undertaken to appreciate the characteristics of adaptability and multi-functionality in buildings whether on a short-term, mid-term and/ or long-term basis. The methodology of the research included exploratory, empirical, and strategic inquiry. Case studies of two prominent buildings under the rich context of adaptable, multi-functional spaces in the event capital of Asia (Hong Kong) and in one of the largest megacities of Africa (Lagos) were examined. These traditional design research methods were also supported with innovative techniques like photography to help better explore existing conditions in and around the study sites. Findings of the case studies have shown that a design approach based on adaptability and multi-functionality of spaces relative to different activities for different times as well as evolving needs is possible and should be adopted, instead of allowing buildings become inefficient shells or waste products of a fast paced world.Keywords: adaptability, multi-functionality, time, use, buildings of the future
Interval Forecast for Smooth Transition Autoregressive Model
Authors: Ekhosuehi Nosa
Published: February 2016

In this paper, we propose a simple method for constructing interval forecast for smooth transition autoregressive (STAR) model. This interval forecast is based on bootstrapping the residual error of the estimated STAR model for each forecast horizon and computing various Akaike information criterion (AIC) function. This new interval forecast suggest definite and better coverage to the future sample path than the conventional method of using a multiple of standard error of the forecast distribution using bootstrap method. Simulation studies are used to illustrate the proposed method.Keywords: AIC; bootstrap; Interval forecast; STAR

Published: February 2016

The study investigated the influence of gender and cognitive styles on students' achievement in biology in senior secondary schools in Anambra State. One research question and one null hypothesis tested at 0.05 level of significance guided the study. A causal comparative research design and a population of 12,000 (SSII) biology students in sixty-four government - owned secondary schools in Awka Education zone. The sample of the study consisted of 265 SSII biology students (141 males and 124 girls) drawn from four government owned schools comprising of two (2) boys and two (2) girls' school in Awka education zone. The sample was drawn using disproportionate stratified random sampling technique. Two instruments were employed for data collection namely: Group Embedded Figure Test (GEFT) and Biology Achievement Test (BAT). GEFT was used to access the cognitive styles of students as either field -dependent or field independent. It is a standardized instrument with a reliability of 0.89 on a test re-test method. BA T content validity was ensured by a test blueprint while face validity was ensured by two biology educators and one expert in measurement and Evaluation from  the science Education Department, University of Nigeria, Nsukka. The reliability coefficient of BAT was established using Cronbach Alpha which gave 0.86. Mean and standard deviation was used to answer the research question while one-way Analysis of variance (ANOVA) was used to test the null hypothesis. Result showed among others: that gender and cognitive styles has no significant, influence on achievement scores of students in biology. Recommendations and conclusion were highlighted.Keywords: Gender, Cognitive styles, Achievement, Biology

The study was conducted to determine the influence of physical format on users’ satisfaction with information resources in university libraries in South-South zone of Nigeria. Survey research method was adopted for the study. The population of this study consists of 83 library staff and 7426 lecturers in the 11 university libraries in the zone during the 2011/2012 academic session. A sample of 36 library staff and 4627 lecturers from 6 of the universities in the zone was used. The researcher made questionnaire, Physical Format and Users’ Satisfaction with Information Resources (PFUSIRQ), was used to collect data. Means and standard deviations were used in answering the research question while the hypothesis was tested using t-Test in IBM SPSS for Window version 20 at p = 0.05 level of significance. The findings revealed that there was no significant influence of physical format on users’ satisfaction with information resources in university libraries in the South-South zone of Nigeria. There is a strong indication that users were satisfied with physical format of the information resources acquired in the university libraries studied. It is therefore recommended that librarians should continue to take cognizance of the variable, physical format when acquiring information resources for the libraries.Keywords: Physical Format; Users’ Satisfaction; Information Resources
Impact of Prior Knowledge of Behavioural Objectives on Students' Academic Achievement in Physics
Authors: Udo Ndem Nsungo , Ubana Arikpo Ubana
Published: February 2016

This study investigated impact of prior knowledge of behavioural objectives on students' academic achievements in physics. The quasi-experimental research design was used for the study. The sample for the study consisted of a total of one hundred and eighty eight (188) students drawn from secondary schools in Yakurr and Abi Local Government Areas of Cross River State. Ten secondary schools were used for the  study. Five schools were purposively assigned to the experimental group while the other five schools were assigned to the control group. The instrument for data collection was the Atomic Physics Achievement Test (APAT) which consisted of fifty (50) items of multiple choice in nature. The instrument had a reliability index of 0.89 using the Kuder-Richardson formula -20. After pretest both groups were taught the concept of atomic physics but with the experimental group given the behavioural objectives before commencement of treatment. The data collected were analyzed using analysis of covariance with pretest scores as covariate. The results of the study showed significant difference in academic achievement between the experimental and control groups, significant difference in achievement between male and female students with the females taking the lead and a significant interaction effect between treatment and gender of the students. It was concluded that prior knowledge of behavioural objectives promote students’ academic achievement. Hence, it was recommended, among others, that physics teachers should be encouraged to give students behavioural objectives prior to the teaching of the concept.Keywords: Prior Knowledge; Behavioural Objectives; Academic Achievement; Physics
