Meta-analysis on the mandibular dimensions effects of the MARA appliance in patients with Class II malocclusions
Authors: Al-Jewair Thikriat S. 
Published: September 2014

ABSTRACT

Objectives:
To evaluate the short- and long-term effects of the mandibular anterior repositioning appliance (MARA) on mandibular dimensions in patients with Class II malocclusion and to assess the stability of the MARA results.

Materials and Methods:
Multiple electronic databases were searched for articles published in any language until March 2014. A manual search was also performed of reference lists of retrieved articles. The primary outcomes were the short-and long-term effects of the MARA appliance on mandible dimensions. The secondary outcome was postretention stability. Outcome measures were total mandibular unit length, corpus length, and ramus height. Two reviewers examined all articles independently and assessed their methodologic quality. Meta-analyses were conducted using random-effects models. The Cochrane test and the I2 statistic were used to assess heterogeneity. Sensitivity analyses were performed and publication bias was evaluated.

Results:
Seven retrospective clinical controlled studies that compared MARA with controls were included. Three of the studies were medium quality; the rest were low quality. Meta-analysis of the short-term effects revealed a significant increase in total mandibular unit length (1.16 mm/y) and ramus height (1.58 mm/y) with MARA and a nonsignificant increase in corpus length (0.21 mm/y). Analyses of the long-term effects showed a statistically significant advantage of MARA over controls for all three variables, but the effect sizes were small. More high-quality studies are warranted.

Conclusions:
The MARA appliance produced statistically significant mandibular growth enhancement in the short- and long-term. These findings, however, may not be clinically significant.
Dancing and Calculating: Culturally sustainable development and globalization in light of two paradigms of socio-cultural evolution
Authors: Katunarić Vjeran 
Published: September 2014

Abstract
Globalization challenges the usefulness of different paradigms of socio-cultural evolution and opens the possibility for their hybridization. In this paper, two paradigms of evolution, the transformational (Spencerian) and the variational / selectionist (Darwinian), as discerned by Fracchia and Lewontin (1999), are examined along with their social theoretical counterparts. Most social theories of development are connected to different evolutionary paradigms in different historical contexts. The transformational paradigm prevailed until the end of the Cold War (e.g. theories of modernization), and the selectionist paradigm, in various theoretical forms, thereafter (e.g. Huntington, Eisenstadt). Most developmental policies today prefer the selectionist paradigm in terms of the neoliberal free market. The transformational paradigm in development policies was predominant in the era of the welfare state in the West, and its counterpart in the era of the statism of the East. Sustainable development in a socio-cultural sense is the youngest and the least consistent policy concept, and it is not founded on the evolution paradigms. The concept was launched by the UN as an attempt at mediating, mostly on the grounds of ecological alarms, between the free-market and statist policies. The author considers the hybridization of these two paradigms to be a proper conceptual foundation of sustainable development. On this premise, he expounds the concept of a culturally oriented sustainable development, arguing that hybrids of developmental policies are more suitable for a decent survival of most countries.
Unexpected Final Vowel Retention in Malakula
Authors: Lynch John 
Published: September 2014

Abstract
Almost all of the thirty or so languages of Malakula in Central Vanuatu show a rule deleting
word-final Proto-Oceanic vowels, suggesting that wholesale final vowel deletion might be reconstructible to
Proto-Malakula. Two sets of languages, however, show vowel deletion only in certain phonological contexts
(and those contexts are different), and retain final vowels in other contexts: a group of four languages in the
north, and the Ninde language in the southwest. This paper describes vowel deletion in these languages,
and shows that the process of wholesale final vowel deletion, far from being an early rule in Malakula, must
have occurred well after Proto-Malakula broke up into various descendant groups or languages, and that it
probably occurred on at least seven different independent occasions.
Investigating Jeffery-Hamel flow with high magnetic field and nanoparticle by HPM and AGM
Authors: Rostami A. , Akbari M. , Ganji D. , Heydari S. 
Published: September 2014

AbstractIn this study, the effects of magnetic field and nanoparticle on the Jeffery-Hamel flow are studied using two powerful analytical methods, Homotopy Perturbation Method (HPM) and a simple and innovative approach which we have named it Akbari-Ganji’s Method(AGM). Comparisons have been made between HPM, AGM and Numerical Method and the acquired results show that these methods have high accuracy for different values of α, Hartmann numbers, and Reynolds numbers. The flow field inside the divergent channel is studied for various values of Hartmann number and angle of channel. The effect of nanoparticle volume fraction in the absence of magnetic field is investigated.It is necessary to represent some of the advantages of choosing the new method, AGM, for solving nonlinear differential equations as follows: AGM is a very suitable computational process and is applicable for solving various nonlinear differential equations. Moreover, in AGM by solving a set of algebraic equations, complicated nonlinear equations can easily be solved and without any mathematical operations such as integration, the solution of the problem can be obtained very simply and easily. It is notable that this solution procedure, AGM, can help students with intermediate mathematical knowledge to solve a broad range of complicated nonlinear differential equations.
First Trip Abroad: Expectations, Experiences and Stories of Transnational Romanians
Authors: Croitoru Alin 
Published: September 2014

Abstract
The paper analyzes transnational Romanians’ stories about their first trip abroad. The concept of physical mobility is seen in a broader framework for understanding transnational and cosmopolitan behaviours as well as international migration. In order to distinguish between different types of travelling for the first trip abroad the article is constructed keeping in mind the structural changes and constraints regarding physical mobility for Romanian citizens. During the process of transition from a communist country to the status of EU member, Romanian citizens’ stories about travelling abroad for the first time fundamentally changed. Labour migrants, asylum seekers, business travellers, students or tourists left the countries with different expectations and faced different problems at destination. Their attitudes toward origin and destination framed their images about the first trip abroad. Using a qualitative approach and samples of Romanians who live in Denmark, Germany, Italy, Romania, Spain and the United Kingdom, the analysis emphasizes certain differences between different types of travelling for the first time abroad and reconstructs how Romanians started their transnational careers
From Progress to Happiness: Measurements for Latin America
Authors: Levy-Carciente Sary , Phélan Luis Mauricio , Perdomo Jhoner 
Published: September 2014

Abstract
This paper is based on a transformed concept of development: from a concept of development that is single-dimensional, concrete, and mainly quantitative, into one that is multidimensional. We focus on the components of development, the measurement of which includes qualitative observations of its effect on final beneficiaries. Because a useful understanding of development policies requires an evaluation of all the different metrics that emerge, we evaluate the development indices of 19 Latin American countries. The most recent theoretical perspectives link development to both liberal philosophy - focusing on the many dimensions of human society and the fundamental rights of the individual - and utilitarianism - emphasizing an evaluation of the success of various development policies and the usefulness of their outcomes.
On Commutation Properties of the Composition Relation of Convergent and Divergent Permutations (Part I)
Authors: Wituła Roman , Hetmaniok Edyta , Słota Damian 
Published: September 2014

Abstract
In the paper we present the selected properties of composition relation of the convergent and divergent permutations connected with commutation. We note that a permutation on ℕ is called the convergent permutation if for each convergent series ∑an of real terms, the p-rearranged series ∑ap(n) is also convergent. All the other permutations on ℕ are called the divergent permutations. We have proven, among others, that, for many permutations p on ℕ, the family of divergent permutations q on ℕ commuting with p possesses cardinality of the continuum. For example, the permutations p on ℕ having finite order possess this property. On the other hand, an example of a convergent permutation which commutes only with some convergent permutations is also presented.
Stereotactic radiosurgery with and without embolization for intracranial arteriovenous malformations: a systematic review and meta-analysis
Authors: Xu Feng , Zhong Junjie , Ray Abhishek , Manjila Sunil , Bambakidis Nicholas C. 
Published: September 2014

Object
The effectiveness and risk of stereotactic radiosurgery (SRS) in the management of partially embolized intracranial arteriovenous malformations (AVMs) remain controversial. The aim of this analysis was to assess current evidence regarding the efficiency and safety of SRS for AVM patients with and without prior embolization.

Methods
To compare SRS in patients with and without embolization, the authors conducted a meta-analysis of studies by searching the literature via PubMed and EMBASE for the period between January 2000 and December 2013, complemented by a hand search. Primary outcome was the rate of AVM obliteration on a 3-year follow-up angiogram. Secondary outcome was the rate of hemorrhage at 3 years after SRS. Tertiary outcome was permanent neurological deficits related to radiation-induced changes.

Results
Ten studies eligible for analysis included 1988 patients: 593 had undergone embolization followed by SRS and 1395 had undergone SRS alone. The AVM obliteration rate was significantly lower in patients who had undergone embolization followed by SRS than in those who had undergone SRS alone (41.0% vs 59%, OR 0.46, 95% CI 0.37–0.56, p < 0.00001). However, the rates of hemorrhage (7.3% vs 5.6%, OR 1.17, 95% CI 0.74–1.83, p = 0.50) and permanent neurological deficits related to radiation-induced changes (3.3% vs 3.4%, OR 1.41, 95% CI 0.64–3.11, p = 0.39) were not significantly different between the two groups.

Conclusions
Embolization before SRS significantly decreases the AVM obliteration rate. However, there is no significant difference in the risk of hemorrhage and permanent neurological deficits after SRS alone and following embolization. Further validation by well-designed prospective or randomized cohort studies is still needed.
Stereotactic radiosurgery of intracranial arteriovenous malformations and the use of the K index in determining treatment dose

Published: September 2014

Object
The appropriate dose during stereotactic radiosurgery (SRS) of cerebral arteriovenous malformations (AVMs) remains a matter of debate. In the present study, the authors retrospectively evaluated the association of using a prescribed dose calculated utilizing the K index with the obliteration rate of cerebral AVMs after SRS.

Methods
The authors performed a retrospective analysis of the Cleveland Clinic SRS database. All patients undergoing Gamma Knife radiosurgery for cerebral AVMs from 1997 to 2010 were selected. Regression techniques and Kaplan-Meier analyses were used to investigate the effect of divergence from the optimal K index dose on the rate of AVM obliteration.

Results
In the study period 152 patients (mean age 43.6 years; 53.9% of treatments were performed in females) underwent 165 Gamma Knife radiosurgery treatments for AVMs. In a univariate analysis Spetzler-Martin grade (OR 0.63 [95% CI 0.42–0.93]), higher AVM score (OR 0.43 [95% CI 0.27–0.70]), larger AVM volume (OR 0.88 [95% CI 0.82–0.94]), and higher maximum diameter (OR 0.56 [95% CI 0.41–0.77]) were associated with a lower rate of AVM obliteration. Higher margin dose (OR 1.16 [95% CI 1.08–1.24]) and higher maximum dose (OR 1.08 [95% CI 1.04–1.13]) were associated with a higher obliteration rate. To further examine the effect of prescribed dose divergence from the calculated K index dose, cases were classified to groups depending on the AVM volume and dose variance from the ideal K index dose. Contingency tables and Kaplan-Meier curves were then created, and no significant differences in rates of obliteration were noted among the different groups.

Conclusions
Gamma Knife radiosurgery for cerebral AVMs remains an effective and safe treatment modality. Smaller AVMs may receive doses less than the calculated K index dose without an apparent effect on obliteration rates.

Published: September 2014

Spinal vascular lesions are rare and may be classified as a) dural arteriovenous fistulas (AVFs), b) arteriovenous malformations, or c) perimedullary AVFs. In this narrated video illustration, we present the case of a 71-year-old woman who presented with progressive bilateral lower extremity weakness and urinary retention who was diagnosed with a thoracic spinal perimedullary arteriovenous fistula. The diagnostic studies included a thoracic MRI and spinal angiogram. A multilevel thoracic laminoplasty was performed for microsurgical obliteration of the AVF. The techniques of intraoperative angiography, thoracic laminoplasty and microsurgical obliteration and resection of the AVF are reviewed.The video can be found here: http://youtu.be/5vVp3oq5sLg.

The square divisor cordial labeling is a variant of cordial labeling and divisor cordial labeling. Here we prove that the graphs like flower Fln, bistar Bn,n, square graph of Bn,n, shadow graph of Bn,n as well as splitting graphs of star Kl,n and bistar Bn,n are square divisor cordial graphs. Moreover we show that the degree splitting graphs of Bn,n and Pn admit square divisor cordial labeling. © 2014 JSR Publications. ISSN: 2070-0237 (Print); 2070-0245 (Online).

L'élaboration familiale des traumatismes psychiques en thérapie : une illustration clinique
Authors: Calicis Florence 
Published: September 2014

Face à un trauma qu’elles n’arrivent pas à assimiler, les familles et les individus qui la composent, mettent en place des mécanismes de défense pour contenir la souffrance. Ces mécanismes sont initialement des facteurs de protection mais, à terme, ils peuvent se muer en facteurs de risque et contribuer à l’émergence de symptômes invalidants, et ce, sur plusieurs générations. Certains de ces mécanismes sont de type « évitement ». Le silence s’installe autour des traumatismes qui s’enkystent progressivement. Une situation clinique illustre comment reprendre en thérapie familiale l’élaboration d’anciens traumatismes enkystés.
En amont du Portrait du colonisé d’Albert Memmi :aux sources d’une pensée de la décolonisation
Authors: Sanson Hervé 
Published: September 2014

Le présent article entend présenter et analyser deux textes de jeunesse de l’intellectuel franco-tunisien Albert Memmi, l’un inédit, l’autre publié dans une revue locale : avant le célèbre Portrait du colonisé qui fut une bible de la lutte anticolonialiste de par le monde, la pensée du jeune Memmi s’est élaborée progressivement, en tâtonnant, ainsi que la prise en compte des manuscrits et tapuscrits de ces deux textes le souligne. En effet, le premier texte ici traité se limite à préconiser une réforme profonde du système colonial, tandis que le second texte prend déjà acte d’une iniquité irréductible du colonialisme, et appréhende le problème tunisien (et au-delà nord africain) de façon globale, et non par sa seule dimension économique, ainsi que la gauche française de l’époque le recommande.
Sony Labou Tansi, afflux des écrits et flux de l’écriture
Authors: Martin-Granel Nicolas 
Published: September 2014

Cet état des lieux des archives laissées par Sony Labou Tansi comprend deux volets. Le premier se présente comme un historique de la sauvegarde et de la valorisation des écrits qui constituent un continent immense et inédit. Leur histoire mouvementée est racontée à partir du moment où l’écriture s’arrête, lors la disparition de l’écrivain en 1995. Matériellement, les écrits sont couchés, pour la plupart, dans des cahiers d’écolier jetés en vrac au fond de la petite bibliothèque de sa maison de Makélékélé à Brazzaville. Sans date, parfois sans titre, ils représentent un véritable défi à la critique génétique qui cherche à les classer, les inventorier, les numériser et enfin à les éditer. Reconstituer leur parcours, au fil des multiples versions et transformations successives, aboutit à dresser la cartographie du labyrinthe textuel constitué non seulement du fonds SLT séparé entre la France et le Congo mais aussi des cahiers et lettres disséminés par l’auteur auprès de ses nombreux amis lecteurs et éditeurs. Dans le second volet, on s’attache à retrouver le fil conducteur de l’écriture, à en restituer la logique vitaliste et hypertextuelle. Si SLT écrivait comme on respire, son écriture, d’allure improvisée, décrite par la génétique comme « à processus », relève, du point de vue anthropologique, du prophétisme scripturaire : un dire-écrire en progression continue – contre le progrès, sans jamais se retourner vers la lecture.
Hospitalité et hostilité : le multilinguisme à l’épreuve du « bien-écrire »
Authors: Montini Chiara 
Published: September 2014

Le multilinguisme représente une menace pour les frontières de chaque langue. Ainsi, pour ne pas courir le risque d’être envahies, les langues établissent leurs règles. Même après Gadda, et dans un pays comme l’Italie, où les dialectes ont toujours existé et où il a été difficile d’établir les normes d’une langue nationale stable, les éditeurs, les critiques, les traducteurs et les écrivains peuvent essayer de normaliser un texte pour qu’il soit intelligible, c’est-à-dire « bien écrit ». Les romans Giù la piazza non c’è nessuno de Dolores Prato et Ur-Partigiano Johnny de Beppe Fenoglio illustrent comment un style très personnel et original peut être modifié par une main extérieure (un réviseur ou bien un éditeur ou encore un traducteur) qui essaie de le faire rentrer dans une norme linguistique en violant son idiolecte « impur » et multilingue.
Cleanliness of Disposable vs Nondisposable Electrocardiography Lead Wires in Children
Authors: Addison Nancy , Quatrara Beth , Letzkus Lisa , Strider David , Rovnyak Virginia , Syptak Virginia , Fuzy Lisa 
Published: September 2014

Background
Mediastinitis costs hospitals thousands of dollars a year and increases the incidence of patient morbidity and mortality. No studies have been done to evaluate adenosine triphosphate (ATP) counts on disposable and nondisposable electrocardiography (ECG) lead wires in pediatric patients.

Objective
To compare the cleanliness of disposable and nondisposable ECG lead wires in postoperative pediatric cardiac surgery patients by measuring the quantity of ATP (in relative luminescence units [RLUs]). ATP levels correlate with microbial cell counts and are used by institutions to assess hospital equipment and cleanliness.

Methods
A prospective, randomized trial was initiated with approval from the institutional review board. Verbal consent was obtained from the parents/guardians for each patient. Trained nurses performed ATP swabs on the right and left upper ECG cables on postoperative days 1, 2, and 3.

Results
This study enrolled 51 patients. The disposable ECG lead wire ATP count on postoperative day 1 (median, 157 RLUs) was significantly lower (P &lt; .001) than the count for nondisposable ATP lead wires (median, 610 RLUs). On postoperative day 2, the ATP count for the disposable ECG lead wires (median, 200 RLUs) was also lower (P = .06) than the count for the nondisposable ECG lead wires (median, 453 RLUs).

Conclusion
Results of this study support the use of disposable ECG lead wires in postoperative pediatric cardiac surgery patients for at least the first 48 hours as a direct strategy to reduce the ATP counts on ECG lead wires.
GESTÃO DE RESÍDUOS SÓLIDOS URBANOS NA REGIÃO METROPOLITANA DE CURITIBA: POLÍTICA REGIONAL DE COMPOSTAGEM
Authors: Nascimento Neto Paulo , Moreira Tomás Antonio 
Published: September 2014

A questão dos resíduos sólidos tem adquirido cada vez mais relevância nas discussões referentes ao planejamento urbano. E, na busca pela sustentabilidade ambiental as soluções contidas na esfera municipal perdem eficiência, visto que os sistemas ambientais sofrem degradações em extensões que extrapolam os limites do município. Neste sentido, destaca-se a figura do Consórcio Intermunicipal, integrando municípios vizinhos com problemas comuns, que reúnem esforços em busca de soluções. Acreditando neste pressuposto foi que em 2001, 17 municípios da Região Metropolitana de Curitiba (RMC) constituíram o Consórcio Intermunicipal Para Gestão de R.S.U.. Dentre as atividades do consórcio, está o Plano de Gerenciamento do Tratamento e Destinação de Resíduos Sólidos (PGRS), que propõe a substituição do atual Aterro Sanitário da Caximba por uma Planta de Tratamento, processando o lixo e aterrando apenas os rejeitos últimos. Porém, este novo sistema proposto não apresenta estratégias de implantação na prática. Neste sentido, este artigo propõe a elaboração de uma Política Regional de Compostagem, definindo diretrizes de planejamento territorial, de modo a viabilizar a prática da compostagem na RMC.
