Variations of Solar Oblateness with the 22 yr Magnetic Cycle Explain Apparently Inconsistent Measurements
Authors: Irbah Abdanour , Mecheri Redouane , Damé Luc , Djafer Djelloul
Published: April 2019

Solar oblateness results from distortion processes due to several phenomena inside of the Sun, but it can also be induced by the centrifugal potential of surface rotation. This fundamental parameter is of great scientific interest, yet for more than a century its measurements have remained a controversial topic, whether because of its average value or its variations observed (or not) over time. Special images acquired for almost the whole of Cycle 24 by the Helioseismic and Magnetic Imager on board the Solar Dynamic Observatory are used for calculating solar oblateness. The average oblateness obtained is 8.8 ± 0.8 mas, in good agreement with measurements over the last two decades. Variations are observed in anti-phase with the solar activity during Cycle 24, whereas they were in phase with activity during Cycle 23. More generally, the trend of both in-phase variation during odd cycles and anti-phase variation during even cycles is confirmed when revisiting past measurements. Therefore, it is possible that the Sun initiates a physical process resulting in a pulsation with the 22 yr magnetic cycle; it has extreme values during the polarity reversals, with a maximum swelling during odd cycles and the opposite for even ones. This oscillation could resolve the controversy surrounding past measurements.

This work aims to increase the floristic knowledge of southern Tuscany by means of a floristic investigation which took place in the Miniera di Murlo (southern Tuscany, Italy). The study area, located in the province of Siena, has an extension of 2.26 km2 and hosts a heterogeneity of habitats like rocky outcrops, woodlands, meadows and riparian formations. The prevalent geological type is an acidic sedimentary rock known as diaspri formation (jasper). The checklist of vascular flora consists of 501 taxa and includes six endemics and 13 alien species, among which Vitislabrusca is a newly-found species for the Province of Siena along with the native Rosabalsamica and Rosasquarrosa. The most interesting species, such as Anthoxanthumaristatum, Gageabohemica, Paragymnopterismarantae, Saxifragagranulata, and Teesdaliacoronopifolia, are found on acidic rocks. Species of the Italian Red List, such as Ruscusaculeatus, and species of Regional conservation interest, such as Centaureaaplolepasubsp.carueliana, Ervilialoiseleurii, and Vicianigricans, were recorded. The chorological spectrum reveals a dominance of Mediterranean species indicating warm climate conditions and mild winters whereas the life-form spectrum shows a slight dominance of hemicryptophytes followed by therophytes. However, a clear dominance of one life-form type over the other is lacking, since the acidic and dry rocky substrate partially compensates for the humidity provided by the stream. This study highlights the relevant floristic value of the Miniera di Murlo area and supports the possible creation of a protected area or its inclusion in the adjacent one.
Pharmacological correction of endothelial dysfunction using ademethionin and taurine
Authors: Khadiyeva Taisiya A. , Pokrovskaya Tatyana G. , Belousova Yuliya V.
Published: April 2019

Introduction: Рharmacological correction of endothelial dysfunction is a urgent problem of modern medicine.

Materials and methods: Endothelial dysfunction was simulated in male rats using the e-NOS inhibitor L-NAME (25 mg/kg/day intraperitoneally, for 7 days). Simulation of ADMA-like preeclampsia was performed by intraperitoneal injection of L-NAME to females in the same doses for 7 days (14-20th days of pregnancy). These pathologies were corrected by administering ademethionine in dose 150 mg/kg and taurine at a dose of 260 mg/kg, as well as their com­bination at the same doses, intragastrically, through an atraumatic probe, once a day.

Results: In the group with use of taurine at a dose of 260 mg/kg the coefficient of endothelial dysfunction decreased to the level of intact animals. Use of ademethionine at a dose of 150 mg/kg and taurine at a dose of 260 mg/kg combined resulted in the most pronounced endothelioprotective effect on the ADMA-like preeclampsia model. The coefficient of endothelial dysfunction decreased more than when using monotherapy of these drugs. Morphological studies of myo­cardiocytes showed that the combination of ademethionine at a dose of 150 mg/kg and taurine at a dose of 260 mg/kg prevented an increase in the cross-section of cardiomyocytes.

Discussion: Possibly, ademethionine and taurine have an endothelioprotective effect because of their ability to decrease hyperhomocysteinemia.

Conclusion: The investigated drugs showed pronounced endothelioprotective activity and can be recommended for further pre-clinical studies.
De l’impuissance à l’impossible

Ce récit qui évoque l’arrêt d’une supervision met en perspective la transformation des pratiques cliniques avec l’arrivée du comportementalisme auprès d’adultes autistes. Le style engagé permet de transmettre que l’analyste qui intervient dans ces croisements-là le fait au risque du transfert et se pose à chaque étape la question de sa fonction et de ce qu’il sert, tour à tour une parole en mouvement dans l’éthique analytique ou bien le clivage institutionnel. La dépressivité de l’impuissance, ou la clinique de l’impossible. La question du cadre des supervision est posée. Si l’éthique de la psychanalyse, pour qui suit Lacan, est celle du désir, que devient la fonction du superviseur à l’ère des protocoles ?

L’auteur expose son éthique de la supervision clinique institutionnelle. Pour lui, ces dispositifs doivent aider les équipes à prendre de la hauteur ( supervidere ) par rapport au réel de leur pratique socioprofessionnelle. La supervision ne saurait être un acte standardisé puisqu’il est nécessaire de travailler dans ce qu’il y a de singulier dans la clinique. Un des buts visés est un allègement de l’impact des situations professionnelles, le sujet en supervision s’en allège par sa participation active à ces espaces du dire, et peu à peu vivra une meilleure conscientisation de son agir professionnel.
L’analyse de pratique ou comment rester soi-même

On dit communément que les enfants grandissent, que les ados mûrissent et que les « profs » prennent de la bouteille – sous-entendu se bonifient, deviennent « meilleurs » tel un bon vin. Certes ! Il y a pourtant plus efficace que le nombre des années pour aider un enseignant à faire son métier avec plus de sérénité : l’analyse des pratiques professionnelles. Ce nom ronflant désigne un dispositif simple encadré par un professionnel, permettant à des enseignants volontaires de se réunir, au mieux, deux fois par mois pour échanger sur leurs pratiques, leurs questionnements, leurs petits bonheurs et leurs grands malheurs qui jalonnent leur quotidien. Bureau des pleurs ? Cet article devrait dissuader les plus réticents d’adopter un tel jugement. À travers le récit d’une situation réelle – en l’occurrence un accrochage entre un élève et une enseignante –, ce témoignage tente d’illustrer le rôle positif que joue l’ app dans l’exercice du métier d’enseignant. Il ne s’agit pas là d’écrire une tribune mais plutôt de montrer que l’ app , souvent méconnu, redonne du sens, de l’humanité à nos pratiques. Il fait tomber les masques, permettant à chacun de se sentir écouté, considéré. Ce n’est pas unilatéral. Les bienfaits de l’analyse rayonnent jusque dans nos classes, offrant aux élèves la possibilité de bénéficier du cheminement d’un enseignant détoxiqué, pleinement conscient d’enseigner avec ce qu’il est, en accord avec lui-même.

Published: April 2019

Gas turbines are very important because they can be used in several areas, such as aeronautics and electric power generation systems. The operation of a gas turbine can be done by less pollutant fuels when compared to traditional kerosene, for example, resulting in less degradation to environment. Gas turbines may fail from a variety of sources, with the possibility of serious damage results. In this work, the structural integrity of the hot disc of an aeronautical gas turbine is addressed. Several numerical analyses have been performed by the finite element method: Temperature Distributions, Thermal Stresses and Dilatations, Structural Stresses and Deformations, Modal Behaviors and Fatigue Analysis. Creep of blades has also been considered. These are the most important failure modes that can happen to the studied hot disc under operating service. All these analysis have been performed considering the boundary conditions at the design point with maximum rotational speed. The mesh of the problem has been strictly evaluated by adaptive refinement of nodes and elements combined with a convergence analysis of results. Then, the material and basic properties of the hot disc have been defined to assure a normal operation free from failures. Therefore, the mechanical drawings of the studied hot turbine disc have been released for manufacturing and the construction of the first prototype of the aeronautical gas turbine is in testing phase showing that the results presented in this work are consistent.
The Behavior Study of Reinforced Concrete in an Aggressive Environment
Authors: Khial Nassima , Bellal Youcef
Published: April 2019

Concrete is today the most widely used building material in the world; it has experienced a real boom in its association with steel in reinforced concrete. The mechanical and chemical complementarity between these two materials has made it possible to build economically and reliably the structures required for all human activities, hence sustainability becomes both a requirement and a major concern of manufacturers. It is therefore essential that the functions of the reinforced concrete are not reduced and that its properties are not altered. However, it is a reactive and a porous material able to the physical and chemical degradations in contact with its environment, due to a chemical reaction between these two media.In this work, we are interested in characterizing and monitoring the ions chloride penetration in reinforced concrete. For this purpose, specimens of the reinforced slab type are made with a composition standardized according to the DREUX-Gorisse method, and we have followed the concrete’ mechanical characteristics evolution in parallel with the immersion / drying cycles’ slab in the sea water. This development was followed with an ultrasound device for a period of about thirty two (32) months. After this period, the reinforcements’ electrochemical behavior by cyclic voltammetry, in these slabs was studied in order to determine the corrosion rate.The results indicated that there is a relationship between the concrete’ strength and the state of its reinforcements with the surrounding environment. On the other hand, the coating thickness is a fundamental parameter of the reinforced concrete durability which makes it possible to lengthen the corrosion initiation.
How Recyclability can Reduce Induction Period of Gold Nanocatalysts
Authors: Ghadamgahi Sedigheh
Published: April 2019

The effect of recyclability on the catalytic activity of supported Au101(PPh3)21Cl5 nanoparticles (1.0 wt% Au101/AC) was investigated for benzyl alcohol oxidation under mild conditions. The influence of recyclability on the catalytic activity of activated Au101/AC nanocatalysts was studied trough a comparison of gold particle diameter and also catalysts conversion between the fresh (as synthesized) and recycled gold catalysts. The monitoring of gold particle diameters by transmission electron microscopy (TEM) showed that the gold particles size gradually increased during the catalytic reaction. The mean diameter of the fresh gold catalysts increased from approximately 3 to 3.2, 5.1 and 5.3 nm after 1, 2 and 3 h reaction time, respectively. Whereas the average gold particle diameter of the recycled samples were slightly enlarged from approximately 5.3 (the sample recycled after 3 h of the first catalytic test) to 5.7, 5.9 and 6.2 nm with durations of 1, 2 and 3 h reaction time, respectively. Therefore, larger gold particles gradually formed for fresh and also recycled gold catalysts during reaction tests. Meanwhile, the catalytic activity of activated 1.0 wt% Au101/AC catalysts jumped to full conversion when the recycled gold catalysts were utilized due to removing ligand stabilizer from gold particles and so bigger particles had formed.
Optical and Morphological Studies of Gold Nano Thin Films on Glass Substrates for Surface Plasmon Resonance Sensors
Authors: Mohammadian Mina , Sari Amir Hossein
Published: April 2019

We have observed surface plasmon resonances (SPR) in Au thin films between 18 nm to 27 nm thick deposited onto glass substrates. The observed resonance angles are between 15.5 to 18.75 degrees, which are lower than predicted theoretical values for thicker films. The shift of resonances with the change of refractive index of surrounding confirms its application for nanobio-sensing. A thorough topological surface analysis and transmitted spectra were performed. Au thin films were annealed in Argon and the analysis repeated and compared with those from pre-annealing. The annealing process will cause a sharper appearance of surface plasmon resonances which will make these thin film devices a more suitable candidate for nanobio-sensing applications.

Published: April 2019

Metallic nanoparticles have various potential applications. Recent studies have showed that their morphology had a strong influence on their optical and electrical properties. In this work, rapid thermal annealing was used to produce gold nanoparticles on silicon substrates. Morphology control of the gold nanoparticles was made by changing inert annealing gases. Spherical gold nanoparticles were obtained with nitrogen while hemispherical gold nanoparticles were formed with argon.
A Requirement for Neutrophil Glycosaminoglycans in Chemokine:Receptor Interactions Is Revealed by the Streptococcal Protease SpyCEP

Published: April 2019

To evade the immune system, the lethal human pathogen Streptococcus pyogenes produces SpyCEP, an enzyme that cleaves the C-terminal α-helix of CXCL8, resulting in markedly impaired recruitment of neutrophils to sites of invasive infection. The basis for chemokine inactivation by SpyCEP is, however, poorly understood, as the core domain of CXCL8 known to interact with CXCL8 receptors is unaffected by enzymatic cleavage. We examined the in vitro migration of human neutrophils and observed that their ability to efficiently navigate a CXCL8 gradient was compromised following CXCL8 cleavage by SpyCEP. SpyCEP-mediated cleavage of CXCL8 also impaired CXCL8-induced migration of transfectants expressing the human chemokine receptors CXCR1 or CXCR2. Despite possessing an intact N terminus and preserved disulfide bonds, SpyCEP-cleaved CXCL8 had impaired binding to both CXCR1 and CXCR2, pointing to a requirement for the C-terminal α-helix. SpyCEP-cleaved CXCL8 had similarly impaired binding to the glycosaminoglycan heparin. Enzymatic removal of neutrophil glycosaminoglycans was observed to ablate neutrophil navigation of a CXCL8 gradient, whereas navigation of an fMLF gradient remained largely intact. We conclude, therefore, that SpyCEP cleavage of CXCL8 results in chemokine inactivation because of a requirement for glycosaminoglycan binding in productive chemokine:receptor interactions. This may inform strategies to inhibit the activity of SpyCEP, but may also influence future approaches to inhibit unwanted chemokine-induced inflammation.

Recent studies showed that about the 8% of beds are occupied by patients who experience a delayed hospital discharge (DHD). This is attributed to a delay in the arrangement of home-care assistance or in admission to long-term care facilities. Recently a lot of technologies have been developed to improve caring and monitoring of older people. The aim of this study is to design, implement and test a prototype of a technology based post-hospitalization facility for older people at risk of DHD by using domotics, robotics and wearable sensors for tele-monitoring. A sensorised posthospitalization facility has been built inside the hospital. Thirty-five healthy volunteers aged from 20 to 82 years were recruited. Clinical and functional assessment, i.e. motility index (MI), and human-robot interaction satisfaction were measured. A significant correlation was observed between automatic MI and the Gait Speed, the time sit-to-stand, and the Timed Up and Go test. Domotics, robotics and technology-based telemonitoring may represent a new way to assess patient’s autonomy and functional and clinical conditions in an ecological way, reproducing as much as possible a real life at home.

Published: April 2019

By using the Rorschach test, self-reports, and psychophysiological measures, we investigated thoroughly the psychological functioning in a hyperhidrotic case. Erica, a young female with hyperhidrosis, was assessed in three times at one-week distance. First, specific tools assessing potential psychological and affective distress, and the Rorschach test were administered. About one week later, Electrodermal Activity was recorded during the exposure to a mild laboratory stress-inducing task. Finally, a magnetic resonance imaging exam was performed in order to exclude medical conditions/neurological alterations for potential physiological anomalies. Erica tends to avoid living in the moment and prefers to experience close relationships in her inner world where she can rehearse the future and imagine different contexts and social situations without risks and embarrassment. She reports high capacities to perform goaldirected behaviors and clarity of emotions only in absence of stressful situations. The study has the merit to be the first to combine Rorschach data with physiological data in order to investigate the psychological functioning in a hyperhidrotic case.

Carrying Jeremy Safran into sessions: relying on internal representations of researchers to facilitate emotion regulation, clinical intervention, and self-efficacy
Authors: Marmarosh Cheri L. , Abbatelli Chiara , Tulipan Molly , Kaleka Jasmine , Ohanesian Jordan , Howson Charlotte
Published: April 2019

Relying on positive internal representations facilitates our ability to feel safe and secure when taking risks and provides a road map to guide us during interpersonal exchanges. Although most graduate programs encourage students to engage in research, we rarely link participating in research as directly influencing positive internal representations that can influence treatment. We used a qualitative method to examine how watching videos of Jeremy Safran, coding therapy sessions using his model, and reading his articles on ruptures and repairs influenced students’ ability to self-soothe, take risks, and engage when patients confront them or withdraw. Results revealed that students often thought of Jeremy Safran and his colleagues during a session and recalled how he addressed ruptures in the videos they watched. When they were anxious during a session, they reported relying on the video coding training to facilitate emotion regulation during sessions. Having the research experience increased their clinical skills and overall clinical self-efficacy. Implications of our findings and future recommendations are discussed.
Cerebrospinal fluid cytology of choroid plexus tumor: A report of two cases
Authors: Kishore Manjari , Gupta Prajwala , Bhardwaj Minakshi
Published: April 2019

Choroid plexus tumors (CPTs) are relatively uncommon tumors of the central nervous system, constituting approximately 5% of all pediatric brain tumors. Although squash cytology of CPT has been described in literature, shedding of tumor cells into cerebrospinal fluid (CSF) has rarely been described. We report two such cases of atypical choroid plexus papilloma in a 5-month-old male child and a 12-year-old female child, where characteristic cytomorphology of CPT was noted in the CSF.
Effect of socio-economic status & proximity of patient residence to hospital on survival in childhood acute lymphoblastic leukaemia
Authors: Totadri Sidharth , Trehan Amita , Kaur Appinderjit , Bansal Deepak
Published: April 2019

Background & objectives:

Survival in paediatric acute lymphoblastic leukaemia (ALL) in lower/middle income countries continues to lag behind outcomes seen in high-income countries. Socio-economic factors and distance of their residence from the hospital may contribute to this disparity. This study was aimed at identifying the impact of these factors on outcome in childhood ALL.

Methods:

In this retrospective study, file review of children with ALL was performed. Patients were treated with the modified United Kingdom (UK) ALL-2003 protocol. Details of socio-economic/demographic factors were noted from a web-based patients’ database. Modified Kuppuswamy scale was used to classify socio-economic status.

Results:

A total of 308 patients with a median age of five years (range: 1-13 yr) were studied. Patients belonging to upper, middle and lower SE strata numbered 85 (28%), 68 (22%) and 155 (50%). Nearly one-third of the patients were underweight. There was no treatment abandonment among children whose mothers were graduates. Neutropenic deaths during maintenance therapy were lower in mothers who had passed high school. In patients who survived induction therapy, the five year event-free survival (EFS) of upper SE stratum was significantly better 78.7±4.9 vs. 59±7.2 and 58.1±4.6 per cent in middle and lower strata (P=0.026). Five year overall survival was higher in the higher SE group; being 91.2±3.5, 78.3±5.6 and 78.8±3.9 per cent (P=0.055) in the three strata. Survival was unaffected by a distance of residence from treating centre or rural/urban residence. High-risk and undernourished children had a greater hazard of mortality [1.80 (P=0.015); 1.98 (P=0.027)].

Interpretation & conclusions:

Our findings showed that higher socio-economic status contributed to superior EFS in children with ALL who achieved remission. Undernutrition increased the risk of mortality.
On the Spurious Mode Generation Induced by Spectral-Like Optimized Interpolation Schemes Used in Computational Acoustics
Authors: Cunha Guilherme , Redonnet Stéphane
Published: April 2019

The present work constitutes a fraction of a more extensive study that is devoted to numerical methods in acoustics. More precisely, we address here the interpolation process, which is more and more frequently used in Computational Acoustics–whether it is for enabling multi-stage hybrid calculations, or for easing the proper handling of complex configurations via advanced techniques such as Chimera grids or Immersed Boundary Conditions. In that regard, we focus on high-order interpolation schemes, so as to analyze their intrinsic features and to assess their effective accuracy. Taking advantage of specific insights that had been previously achieved by the present authors regarding standard high-order interpolation schemes (of centered nature), we here focus on their so-calledspectral-like optimizedcounterparts (of both centered and noncentered nature). The latter spectral-like optimized schemes are analyzed thoroughly thanks to dedicated theoretical developments, which allow highlighting better what their strengths and weaknesses are. Among others, the various ways such interpolation schemes can degrade acoustic signals they are applied to are carefully investigated from a theoretical point-of-view. Besides that, specific criteria that could help in optimizing interpolation schemes better are provided, along with generic rules about how to minimize the signal degradation induced by existing interpolation schemes, in practice.

Рассматривается задача тестирования распределения по выборке на принадлежность семейству многомерных обобщенных скошенно-эллиптических распределений с неизвестными вектором сдвига, матрицей масштаба, распределением симметричной компоненты, у которого задана параметрическая функция скоса с неизвестным значением параметра. Предлагаются статистические критерии, являющиеся функционалами эмпирических процессов, индексированных классами функций. При выполнении слабых условий на гладкость функции скоса и класса функций получена асимптотическая теория для этих тестов. Они состоятельны против любой фиксированной альтернативы, они инвариантны для группы аффинных преобразований, они гибки в применении. Однако предельный процесс зависит от неизвестных объектов очень сложным образом. Для преодоления этой сложности предложена модификация статистического критерия при помощи бутстрепа, показано теоретически, почему она работает, и проиллюстрировано практическое применение на симуляциях.

Null objects/full pronouns and topicality in Brazilian Portuguese
Authors: Cyrino Sonia Maria Lazzarini
Published: April 2019

Sabe-se que o português brasileiro (PB) permite objetos nulos cujos antecedentes são inanimados. Porém, há certas sentenças que parecem desafiar essa generalização. Essas sentenças também permitem pronomes plenos na posição do objeto. Neste trabalho, defendo que a lacuna nessas sentenças não é o objeto nulo característico do PB, ou seja, não há aí uma elipse de DP. A questão, portanto, é como diferenciá-las (i) daquelas contendo o verdadeiro objeto nulo; e (ii) daquelas que só permitem o pronome pleno. Para discutir essas questões, o trabalho tem como base o arcabouço teórico gerativista e parte de recentes propostas para diferentes tipos de tópico, dentro de uma visão cartográfica (FRASCARELLI; HINTERHÖLZ, 2007). Comparando os objetos nulos do PB com o hebraico (ERTESCHIK-SHIR et al., 2013), assumo que diferentes tipos de tópico devem ser distinguidos em termos de seu papel no discurso. O PB, no entanto, não se assemelha ao hebraico em relação ao fenômeno de queda do tópico. Essa discussão embasa a proposta aqui apresentada acerca da distribuição do objeto nulo e pronome pleno no PB. Os objetos nulos animados vs. não-animados do PB são permitidos de acordo com o tipo de tópico presente na periferia à esquerda. O trabalho pretende contribuir para a discussão sobre a alternância objeto nulo/pronome pleno no PB.
PP Relative clauses and intervention effects: comparing unergative and weather verbs
Authors: Augusto Marina R. A. , Grolla Elaine , Rodrigues Erica Dos Santos
Published: April 2019

A assimetria entre relativas de sujeito e de objeto tem sido atestada nos trabalhos sobre processamento com adultos (WANNER; MARATSOS, 1978; WARREN; GIBSON, 2002) e em aquisição da linguagem (UTZERI, 2007; ADANI; SEHM; ZUKOWSKI, 2012). No âmbito da aquisição, Friedmann, Belletti e Rizzi (2009) sugeriram um tratamento formal, em termos de efeitos de intervenção e Costa et al. (2015) expandiram o alcance da proposta para relativas PP, considerando dados do português europeu. Este trabalho amplia essa discussão, a partir de um estudo de eliciação com crianças de 4-5 anos falantes de português brasileiro, contrastando relativas PP, com verbos inergativos, com intervenção, e meteorológicos, sem intervenção. Nossos resultados indicam diferenças entre esses tipos de verbos para crianças mais novas. Sugere-se que o alcance explicativo da hipótese da intervenção pode ser impactado ao se considerarem custos de processamento na produção vinculados à disponibilidade de estruturas alternativas, menos complexas, na língua.
Sobre as interrogativas clivadas (básicas) QU e polares
Authors: Cavalcante de Araújo Rerisson
Published: April 2019

Este artigo descreve as interrogativas clivadas básicas, que não têm recebido atenção na literatura. Estudos sobre clivagem concentram-se nos usos declarativos, e estudos sobre perguntas consideram “interrogativas clivadas” aquelas em que a cópula é omitida ou em que o QU antecede a cópula, que corresponderiam à clivada invertida, não à clivada básica. Aqui, o foco é sobre interrogativas com a estrutura “É __ que...?”. A partir de dados levantados na rede e de julgamentos de intuição, o trabalho descreve propriedades das clivadas básicas QU e polares, discutindo fatos inesperados, como a inaceitabilidade das clivadas QU em perguntas indiretas e a interpretação de pergunta parcial nas clivadas polares. O trabalho propõe uma análise baseada em movimento focal sem checagem do traço [+Wh]. Por fim, discute também a natureza da pressuposição (de existência ou de unicidade/exaustividade) codificada pelas clivadas, mostrando que clivadas QU e polares oferecem evidências contraditórias quanto a esse fenômeno.

Authors: Aghara Vincent NO. , Ogwo Ogwo E. , Ojiaku Obinna C.
Published: April 2019

As the voice-service-market of mobile telecommunication providers fast reaches its saturation amidst increasing competition, its revenue potential to telecom providers continue to decline. Therefore, understanding consumers use behavior portends important strategic consideration for customer acquisition and retention for telecom operators. This study seeks to empirically determine the factors that influence the acquisition of multiple GSM networks by university lecturers in Southeastern universities in Nigeria. Data were generated from a sample of 301 respondents. Three hypotheses were stated and tested using Analysis of variance (ANOVA). The result shows positive relationships between income, social affinity networks, and brand image and consumer acquisition of multi SIM networks. It is therefore, recommended that income, social affinity, and brand image be used as strategic marketing tools to attract customers to acquire a particular network.

Employees’ organizational commitment is considered as a crucial issue in higher education setting for realizing institutional vision, attaining its goals, and uplifting employees’ motivation to achieve better work performance.  This subject has, therefore, been studied so as to draw attention to enhance the effectiveness of Ethiopian higher education institutions with particular reference to Haramaya University. Thus, the main objective of this study was to assess academic staffs’ level of organizational commitment. In addition, the study assessed whether there exist a significant difference in academic staffs’ level of organizational commitment in terms of their gender and level of education. A cross-sectional research design was employed in the study. Primary and secondary data sources were used. A commitment scale questionnaire was used to collect data from 275 participants who were selected using stratified random sampling technique as well as further information about the study were also collected using focus group discussion and document review. The quantitative data were analyzed using both descriptive and inferential statistics; the qualitative data were analyzed using content and narration methods of data analysis. The study revealed that academic staffs of the university have moderate level of organizational commitment. With this level of organizational commitment, it is less likely to attain both individual work performance objectives and organizational missions and vision of the university. In addition, there were relative implications of turnover, turnover intention, absenteeism, and demotivation among academic staffs. The study further revealed that although there is no significant difference in level of commitment with reference to gender, academic staffs’ level of organizational commitment was significantly different with reference to their level of education. Thus, it is recommended that the working environment of the university is revisited by giving due emphasis to and addressing the determinants that lower the organizational commitment of the staff.

Several studies have been carried out in the past to find out how strategic planning and competitive advantage are connected and the causes of differences in competitive advantage among firms. Scholars have argued that competitive advantage can emanate from either internal or external sources and is usually in several forms which include; valuable resources, the position held within the industry, position within the marketplace, operating at lower costs than rival firms, differentiation, capabilities and dynamic capabilities. The debate on what causes differences in competitive advantage is still on. This study sought to establish the moderating effect of organizational structure on the relationship between strategic planning and competitive advantage of large manufacturing firms in Kenya. The study was underpinned by the competitive advantage typology of Michael Porter, the resource-based theory, dynamic capabilities theory, and the contingency theory. The study used a positivist research paradigm and a cross-sectional survey design. This was a census study from 124 large manufacturing firms in Kenya and data was collected from 122 of the firms representing a response rate of 98.4%. The findings indicate that overall strategic planning has a statistically significant influence on competitive advantage and that organizational structure partially moderates the relationship between strategic planning and competitive advantage. The study recommended that once the strategy of the firm has been changed, an organization structure that fits the needs of the new strategy should be put in place. This is because in the absence of an organization structure that fits the needs of the firm, it will be difficult for the firm to achieve and sustain a position of competitive advantage.

Authors: Bee Thai Siew , Ming Lai Ming
Published: April 2019

This study examines the prevalence of earnings management in Real Estate Investment Trust (REIT) funds in Asia. Discretionary Accruals (DA) is used as the measurement of earnings management. A panel data covering all REIT firms in three countries: Malaysia, Singapore and Hong Kong, from year 2007 to 2015 is used for this purpose. The results show all firms having the absolute value of discretionary accruals indicating that earnings management exists in Asian REITs. Further, independent t-test shows that earnings management activities are significantly prevalent in all these three countries despite the regulatory structure of REITs.

The oxidovanadium(V) Schiff base complex of formula [VO(L)(EtO)(EtOH)] (where H2L = Schiff base ligand derived from 5-methoxysalicylaldehyde and phenylacetic hydrazide) was synthesized and described. Complex crystalizes in triclinic P-1 space group. Octahedral geometry of the vanadium(V) centre is filed with oxido, ONO L2- ligand and two solvent molecules both in ethoxo and as neutral ethanol form. The complex is neutral, with 5- and 6-memebered ring formed by ONO ligand coordinated in octahedral plane with oxido and EtOH ligands in vertical positions. Two isomers are present in the unit cell, with different position of 5-membered ring versus vertical plane. The elemental analysis, magnetic susceptibility, thermogravimetry and spectroscopy (IR, UV-Vis) measurements were measured and are discussed. The cyclic voltammetry measurements show irreversible processes for vanadium(IV/V) redox system. Thermal stability both in a solid state (TG and SDTA measurements) as well as in solutions (at pH 7.0 and 2.0, studied by UV-Vis spectroscopy) is discussed.

Vanadium is an element that has an effect on improving glucose levels in animals with diabetes. However, its operation is strongly dependent on the chemical structure of compounds of this element. The influence of newly synthesized vanadium compounds on biochemical processes is also unknown. The paper presents the influence of eight new vanadium compounds on organ weights of animals (mice NZO) in whom diabetes was induced by a high-fat diet during 8 weeks. Tested vanadium complexes were administered by 5 weeks. After this time organs were collected and weighed. Tested complexes had a remarkable different effect on organ weights, despite having similar composition ([VO(L)(phen)] and the same co-ligand (1,10-phenanthroline) . This indicate on separate metabolic pathways of these compounds in the body of tested animals and role of the tridentate L Schiff base ligands. The compounds C2, C3 and C5 shoved biggest influence on organs weight and these results suggest influence on the metabolic pathways and therefore are interesting for further investigations.

OBJECTIVE To compare length of stay (LOS), costs, mechanical ventilation (MV), and mortality in preterm infants treated in the Neonatal Intensive Care Unit (NICU) with beractant (BE), calfactant (CA), and poractant alfa (PA) for Respiratory Distress Syndrome (RDS).

METHODS This study evaluated preterm infants born between 2010 and 2013 with RDS diagnosis, gestational age of 25 to 36 weeks, birthweight of ≥500 g, and age of ≤2 days on first surfactant administration. Multivariable regression was used to evaluate all NICU outcomes.

RESULTS Of 13,240 infants meeting the study criteria, 4136 (31.2%) received BE, 2502 (18.9%) received CA, and 6602 (49.9%) received PA. Adjusted analyses estimated similar mean LOS (BE 26.7 days, CA 27.8 days, and PA 26.2 days) and hospital costs (BE: $50,929; CA: $50,785; and PA: $50,212). Compared to PA, BE and CA were associated with greater odds of MV use on day 3 (OR = 1.56 and 1.60, respectively) and day 7 (OR = 1.39 and 1.28, respectively; all p < 0.05). Adjusted NICU mortality was significantly higher only with CA vs PA (OR = 1.51; p = 0.015).

CONCLUSION Adjusted NICU LOS and costs were similar among BE, CA, and PA. Infants receiving PA were less likely to be on MV at 3 and 7 days, and PA treatment was associated with lower odds of NICU mortality when compared to CA.

OBJECTIVES The purposes of this study are to perform a large-scale evaluation of the standardized dosage adjustment nomogram recommended by the American College of Chest Physicians (CHEST) for the management of enoxaparin in hospitalized pediatric patients and to determine the necessity of routine and repeated anti–factor Xa (anti-Xa) levels.

METHODS A retrospective cohort study was designed, and charts were reviewed in a single tertiary care institution for all patients who received enoxaparin between October 1, 2010, through September 30, 2016. Patients were included if they were receiving treatment doses of enoxaparin according to the pediatric CHEST guidelines, had a subtherapeutic or supratherapeutic anti-Xa level drawn at 3.5 to 6 hours after a dose, had a dose changed in an attempt to attain a therapeutic anti-Xa level, and had a second anti-Xa level drawn 3.5 to 6 hours after the dose change. Descriptive statistical methods were used to characterize the ability of dose adjustment via a nomogram to attain an anti-Xa of 0.5 to 1 unit/mL.

RESULTS A total of 467 patients were identified who received the appropriate initial dose and dosage adjustment and whose levels were drawn according to the CHEST guidelines. In patients who had an initial anti-Xa level of <0.35 units/mL and received the nomogram recommended dose increase of 25% ± 5%, 28 out of 96 patients (29.2%) reached therapeutic levels. Of 197 patients who had an initial anti-Xa level between 0.35 and 0.49 units/mL and who received the nomogram recommended dose increase of 10% ± 5%, 116 (58.9%) reached therapeutic levels. Of 50 patients with an initial anti-Xa level between 1.1 and 1.5 units/mL and who received the nomogram dose decrease of 20% ± 5%, 31 (62%) reached therapeutic levels.

CONCLUSIONS The current dosage adjustment nomogram recommended by the CHEST guidelines does not reliably lead to therapeutic anti-Xa levels when used to adjust enoxaparin doses in pediatric patients.

OBJECTIVES To compare the modified Finnegan Scoring System (modified Finnegan) with an Adjusted Scoring System Criteria (adjusted Finnegan) for infants after cardiothoracic surgery with iatrogenic opioid abstinence syndrome (IOAS).

METHODS This was a retrospective, observational pilot study. This study was conducted in a tertiary care academic hospital. Infants after cardiothoracic surgery with IOAS transferred between the pediatric intensive care unit and neonatal intensive care unit between January 1, 2014, and January 31, 2016, were included retrospectively. The main outcome variable was to compare the area under the curve for the mean modified Finnegan versus adjusted Finnegan.

RESULTS Twenty-five patients were included in the study. Twenty patients with at least 30 scores were included in the final analysis. Overall, the modified Finnegan scores were at least 2 points higher than the adjusted Finnegan. The difference in area under the curve was 34.6 (p < 0.001).

CONCLUSIONS Use of the modified Finnegan tool for older infants with IOAS could overestimate withdrawal, leading to unnecessary interventions.
