Are Gingival Phenotype, Residual Ridge Height, and Membrane Thickness Critical for the Perforation of Maxillary Sinus?
Authors: Yilmaz Hasan Guney , Tözüm Tolga F. 
Published: May 2011

Background: Sinus membrane perforation is the most common complication of the sinus‐augmentation procedure. Anatomic factors have been implicated in the risk of sinus membrane perforation (SMP) during sinus‐lift surgery. However, there are no reports on the relationships among gingival phenotype (GP), residual ridge height (RRH), membrane thickness (MT), and perforation rate of the maxillary sinus. Therefore, the aim of this clinical study is to determine the associations among GP, RRH, MT, and SMP rate.Methods: Forty‐four patients (64 sinus‐lift procedures) were included in the study. Preoperative computed tomography scanning was performed to radiographically evaluate GP, RRH, and MT. The smallest RRH, highest MT, and gingival thickness values were recorded. These values were classified as follows: RRH, < or >3.5 mm; MT, < or >1 mm; and GP, <1.5 or >2 mm. Sinus‐lift surgery was performed with a lateral window approach, and SMPs were detected at 11 sinus sites. Perforation size and locations were recorded, and the perforations were repaired with collagen membrane. One hundred seventy‐six implants were placed immediately after augmentation procedure.Results: Strong correlations of GP with RRH (r = 0.722, P = 0.001) and MT (r = 0.702, P = 0.001) were noted. Moderate correlations were found between RRH and MT (r = 0.596, P = 0.001) and between MT and SMP (r = 0.417, P = 0.001). Furthermore, mild correlations of SMP with RRH (r = 0.290, P = 0.020) and GP (r = 0.248, P = 0.04) were established. Four implants were lost, but no significant difference was found between implant failure and SMP.Conclusion: Within the limits of the study, it may be suggested that GP, RRH, and MT may be important factors for sinus perforation.
Men in Transit and Prostitution: Using Political Conventions as a Natural Experiment
Authors: Cunningham Scott , Kendall Todd D 
Published: June 2011

Abstract
Approximately 100,000 visitors came to Denver, Colorado and Minneapolis, Minnesota to attend the 2008 Democratic and Republican National Conventions. Economic theory suggests that men in transit can shift demand for commercial sex work. We estimate the responsiveness of labor supply to these two conventions, focusing on a previously neglected but increasingly important segment of the prostitution market: indoor sex workers who advertise on the Internet. Using a differences-in-differences estimator of prostitution advertisements posted on a major classified ads website, we find that the conventions caused a 29-44 percent increase in advertisements in Minneapolis and a 47-77 percent increase in Denver. Given the key role prostitution plays in the transmission of STIs, these results imply that focusing public health resources on men in transit may be beneficial.

AbstractThe natural infection with parasitic helminths is common in wild rodent populations. Once such interactions are better understood in the laboratory, it will be more feasible to extend the findings to infected hosts in nature. The flukes recovered from laboratory-infected Akodon cursor at 63 days post-infection were stained with hydrochloric carmine and individually mounted on glass slide as whole-mounts. Light and laser scanning confocal microscopy studies of adult male and female Schistosoma mansoni are reported. The parasites were examined morphologically and biometrically, which was obtained in a digital system for image analysis. Parameters used were: tegument thickness, digestive, excretory and reproductive systems. The overall conclusion of this experiment is that the morphological features of adult worm were similar to laboratory mice. It has been confirmed that the grass mouse is a permissive host to S. mansoni infection.
Ultrastructure of musculature of the marginal hooklets of Macrogyrodactylus congolensis, a monogenean skin parasite from the catfish Clarias gariepinus
Authors: Arafa Safaa 
Published: May 2011

AbstractThe musculature of the marginal hooklets of adult Macrogyrodactylus congolensis (Prudhoe, 1957) Yamaguti, 1963 has been studied. Each marginal hooklet of M. congolensis is associated with three pairs of muscles. The possible role of these muscles in the operation of the marginal hooklet is discussed. Transmission electron microscopy has been used for the first time to study the marginal hooklets of M. congolensis. The handle articulates with the blade in the region of the guard. Internally, the handle, the proximal region of the blade in the articulation region and the distal pointed region of the blade consist of three layers. Distal to the articulation region, the blade consists of four layers with differing electron densities. A cavity is associated with the distal region of the blade and the handle. A cyton containing secretory bodies of different sizes and shapes was found in association with each marginal hooklet. The possible function of these secretions is discussed.
Determinants of Non-Linear Effects of Fiscal Policy on Output: The Case of Bulgaria

Published: June 2011

Determinants of Non-Linear Effects of Fiscal Policy on Output: The Case of BulgariaThe paper illuminates the non-linear effects of the government budget on short-run economic activity. The study shows that in the Bulgarian economy under a Currency Board Arrangement the tax policy impacts the real growth in the standard Keynesian manner. On the other hand, the expenditure policy exhibits non-Keynesian behavior on the short-run output: cuts in government spending accelerate the real GDP growth. The main determinant of this outcome is the size of the discretionary budgetary changes. The results imply that the balanced budget rule improves the sustainability of public finances without assuring a growth-enhancing effect.

Tracking Accuracy of Large and Small-CAP ETFS: an Empirical Analysis Of The Istanbul Stock ExchangeIn this study, we examine the tracking performance of two ETFs, namely DJIST and SMIST, both traded on the Istanbul Stock Exchange, with respect to their own indices. We carry out an analysis first to identify each ETF's tracking ability of underlying index, and second to explore whether any differences exist between the return of large-cap and the return of small-cap stock ETFs, and their indices. By employing a data set of calculated daily returns for the specified ETFs and their corresponding indices, t-tests and regression analyses are conducted. Our findings suggest that both DJIST and SMIST stocks performed well in tracking their own indices' returns. However, the mimicking ability of DJIST stock is better than that of SMIST. Possible explanations regarding this difference are that the SMIST's introduction into the market is relatively new compared to the DJIST, and that the SMIST represents small-cap stocks with considerable illiquidity problems, while the DJIST represents large-cap stocks. Despite the odds, against the SMIST, it still shows a tracking performance that should be acknowledged, given both its place in an emerging market and its strength within such a short period of time.
Air Pollution, Allocation of Property Rights, Environmental Issues and Theoretical Overlapping Generations General Equilibrium Modelling
Authors: Tchouto Jules 
Published: June 2011

Air Pollution, Allocation of Property Rights, Environmental Issues and Theoretical Overlapping Generations General Equilibrium ModellingThis paper presents how the environment - considered as a production factor - and other related assumptions can be introduced step by step in a theoretical Overlapping Generations General Equilibrium Model (OLG - GE). The first part shows the behaviors of agents with pollution in the absence of an environmental policy. The second part emphasizes a Greenhouse Gas abatement policy through the allocation of Pollution Permit ownership, which allows property rights on the environment; here we assume a three-factor model: Capital - Labor - Environment. The last part of of the paper highlights one theoretical property about the allocation of pollution permits within a OLG-GE steady state with the environment. To our knowledge, it is the first time that the aforementioned property has been characterized.
Returns for Education in Kosovo: Estimates of Wage and Employment Premia

Returns for Education in Kosovo: Estimates of Wage and Employment PremiaThis paper provides an analysis of the returns for education in Kosovo using data from a Household and Labour Force Survey. We argue that given the high unemployment rate in Kosovo, employed individuals may not be randomly selected from the labour force. Therefore, the estimates of the rates of returns for education based on the standard Mincerian earnings function may be biased downwards. Hence, the Heckman sample selection model is implemented, which adjusts the estimates of the wage equation for the self-selection of individuals into employment. We estimate the rate of returns for level of education and for years of education. We find relatively low rates of returns for education in terms of wage premia and argue that in countries with chronic labour market disequilibria (such as in Kosovo), the returns for education may be in terms of employment premia. To our knowledge, this is the first systematic study of these issues in this post-socialist and post-conflict economy.

Dynamics of perceiving oneself on femininity and masculinity dimensions in diverse contexts
The article is about issues related to gender perceived as a result of social context and thus fits in the current, processual gender paradigm. Two studies have been conducted verifying hypotheses about perceiving oneself on the femininity and masculinity dimensions in various types of contexts. Expectations were that generic contexts would make perceiving oneself within the psychological gender dimensions more dynamic. Women were expected to perceive themselves as more feminine and less masculine in contexts matching their gender, i.e. "feminine", comparing to "masculine", and men were expected to perceive themselves as more masculine and less feminine in "masculine" contexts comparing to "feminine" contexts. Research results do not confirm the above hypotheses and indicate dynamism in perceiving oneself on femininity and masculinity dimensions. However, the dynamism is perceived only on dimensions inconsistent with biological gender - situation affects women's perceiving of themselves on the masculinity dimension and men's - on femininity dimensions.

AIMS This study compared data quality and response rates for the Alcohol Use Disorders Identification Test (AUDIT) in a web-based versus in a paper-and-pencil format survey. SETTING Subjects were randomised to one of two parallel samples, one web-based and the other paper-based. Data were collected during 2009. Results The web-based format yielded a lower response rate compared to the paper version (26.2% vs. 53.6%), internal consistency was quite similar (0.82 vs. 0.77), while the mean AUDIT scores were higher in the web-based format for both men and women. Conclusions Future studies should focus on methods for combining different administration methods in order to maximize response rates.
Effects of Elevated Body Temperature on Control of Breathing

Effects of Elevated Body Temperature on Control of Breathing
Changes in body temperature can be evoked mainly by alterations in the peripheral temperature, or modified by shifts in the central body temperature. Two conditions can lead to abnormal elevation of body temperature: hyperthermia or fever. As regards respiratory system, exposure to heat stress is accompanied by marked alterations in breathing, especially by an increase in ventilation. Ventilation rises due to an increase in central output from hypothalamus or brainstem, an increase in peripheral output via skin temperature receptors, an increase in central or/and peripheral chemoreceptor output or sensitivity and can be also mediated through changes in thermoregulatory mechanisms.
This review summarizes results of previous studies as well as of experiments done in our laboratory in order to elucidate the mechanisms included in respiratory changes under heat stress.
Asymmetrical Lower Extremity Loading After ACL Reconstruction: More Than Meets the Eye
Authors: Chmielewski Terese L. 
Published: May 2011

Sports fans know that movement patterns are important for athletic performance. Similarly, clinicians know that addressing abnormal movement patterns after an anterior cruciate ligament (ACL) reconstruction is important for a successful return to sport. The kinematic (motion) component of movement patterns is more easily observed than the kinetic (forces) component, thus more commonly addressed in ACL reconstruction rehabilitation. Ignoring the kinetic component, though, could impede a successful return to sport. Asymmetrical lower extremity loading has been reported in a variety of activities following ACL reconstruction, and may contribute to both short- and long-term consequences. It is important that clinicians become aware of the potential for asymmetrical lower extremity loading to affect patient outcomes and for researchers to enlarge the body of knowledge.

Appropriate Use of Diagnostic Imaging in Low Back Pain: A Reminder That Unnecessary Imaging May Do as Much Harm as Good
Authors: Flynn Timothy W. , Smith Britt , Chou Roger 
Published: June 2011

Synopsis The rate of lumbar spine magnetic resonance imaging in the United States is growing at an alarming rate, despite evidence that it is not accompanied by improved patient outcomes. Overutilization of lumbar imaging in individuals with low back pain correlates with, and likely contributes to, a 2- to 3-fold increase in surgical rates over the last 10 years. Furthermore, a patient's knowledge of imaging abnormalities can actually decrease self-perception of health and may lead to fear-avoidance and catastrophizing behaviors that may predispose people to chronicity. The purpose of this clinical commentary is as follows: (1) to describe an outline of the appropriate use, as defined in recent guidelines, of diagnostic imaging in patients with low back pain; (2) to describe how inappropriate use of lumbar spine imaging can increase the risk of patient harm and contributes to the recent large increases in healthcare costs; (3) to provide physical therapists with clear guidelines to educate patients on both appropriate imaging and information to dampen the potential negative effects of imaging on patients' perceptions and health; and (4) to present an example of a successful clinical pathway that has reduced imaging and improved outcomes.

La place de l'intérêt particulier et le rôle du pouvoir dans la démocratie délibérative
Authors: Mansbridge Jane Jebb , Bohman James , Chambers Simone , Estlund David , Føllesdal Andreas , Fung Archon , Lafont Cristina , Manin Bernard , Luismarti José 
Published: May 2011

Résumé Cet article avance, à contre-courant de toutes les théories délibératives existantes, que les intérêts particuliers doivent être pris en compte dans la délibération démocratique. Deux conditions sont cependant nécessaires afin que l'inclusion des intérêts particuliers dans la délibération apparaisse légitime : l'idéal-régulateur d'absence de pouvoir coercitif et l'encadrement des intérêts particuliers par des principes de justice. Ceci conduit à qualifier de « délibératives » des formes de négociation mettant en jeu des intérêts contradictoires, telles que la négociation intégrative et la négociation « parfaitement coopérative ». L'article se conclut en défendant la complémentarité de la délibération et de mécanismes démocratiques agrégatifs et non-délibératifs.
Le projet de la démocratie radicale
Authors: Cohen Joshua , Fung Archon 
Published: May 2011

Résumé Les démocrates radicaux cherchent à promouvoir des institutions qui soient à la fois participatives et délibératives. Le fonctionnement démocratique classique basé sur le gouvernement représentatif peine à respecter ces deux dimensions. Il est par ailleurs difficile d'améliorer simultanément celles-ci. La délibération et la participation constituent deux objectifs distincts, et les efforts visant à promouvoir l'une peuvent se faire au détriment de l'autre. Nous envisageons deux façons d'atténuer ces tensions : la délibération médiatisée (indirecte) à l'échelle de la société tout entière et la délibération participative directe. Chacune de ces voies respecte les exigences du projet démocratique radical à l'égard de la délibération et de la participation, et contribue à promouvoir des valeurs démocratiques fondamentales comme la responsabilité, l'égalité et l'autonomie politique.
La démocratie délibérative à l'épreuve du militantisme
Authors: Young Iris Marion 
Published: May 2011

Résumé Il semble exister une contradiction insurmontable entre deux conceptions du changement social : celle portée par les militants et reposant sur l'action collective et la critique, et celle portée par les théoriciens de la délibération, reposant sur la formulation d'un accord après une discussion rationnelle. En faisant dialoguer ces deux positions, l'article met en lumière certaines limites des normes de la démocratie délibérative, en particulier dans le cadre de sociétés marquées par des inégalités structurelles importantes qui rendent la discussion difficilement équitable. Ce faisant, il éclaire certaines vertus démocratiques des pratiques politiques non délibératives de protestation. Ce n'est qu'en s'ouvrant à des formes critiques et non-argumentatives d'expression que la délibération peut dès lors véritablement être à la hauteur de son idéal d'inclusion et de transformation sociale.
Stoller, l'érotique et l'excitation sexuelle
Authors: Fisher David James 
Published: May 2011

Résumé Cette contribution analyse le livre magistral de R. Stoller, paru en 1979, L’Excitation sexuelle , une des études de cas les plus riches, rédigées de façon particulièrement évocatrice, une des plus complexes et pourtant des plus révélatrices de la littérature psychanalytique. En France, Stoller est surtout connu comme théoricien du genre, mais son exploration analytique de l’érotique mérite d’être reconnue. Cette étude affirme que l’engagement subjectif de Stoller dans l’analyse et l’écriture de l’étude de cas est lui-même un moment transitionnel dans l’histoire de la psychanalyse, une passerelle entre l’analyse de résistances classiques et les approches contemporaines herméneutiques et relationnelles ; sa compréhension et son désaveu du contre-transfert érotique y sont examinés. Les réflexions de Stoller sur l’éthique, la rigueur scientifique et les ambiguïtés conceptuelles d’un récit de cas restent exemplaires et subversives dans le domaine analytique aujourd’hui.
« Coupable... donc capable ?... »
Authors: Lucas Gérard 
Published: May 2011

Résumé Le texte de R. Asséo concerne une situation clinique que ses ambiguïtés multiples rendent particulièrement intéressante : les caractères du fonctionnement du patient rappellent les descriptions classiques, notamment la discrétion du registre surmoïque proprement dit ; alors que la survenue de l’accident somatique sur un fond d’hypertension chez un homme capable de s’irriter suggère quasiment dans le langage courant banal une conception pathogénique implicite proche de celle de l’argument de cette revue. L’auteur s’interroge sur cet écart et sur ses conséquences.
Chemins tortueux de la culpabilité chez Freud
Authors: Nayrou Félicie 
Published: May 2011

Résumé Le sentiment de culpabilité est tôt présent dans la théorie freudienne. Tout au long de l’œuvre, cette notion essentiellement phénoménologique va se présenter de façon protéiforme et va connaître des variations sémantiques qui disent la complexité métapsychologique – au début, Freud parle de « conscience de culpabilité » et ensuite de « sentiment inconscient de culpabilité ». Néanmoins, le fil conducteur est topique, désignant continûment une pression du surmoi sur le moi.

Published: June 2011

Abstract
Dendritic cells (DC) play a key role in establishing protective adaptive immunity in intracellular bacterial infections, but the cells influencing DC function in vivo remain unclear. In this study, we investigated the role of NK cells in modulating the function of DC using a murine Chlamydia infection model. We found that the NK cell-depleted mice showed exacerbated disease after respiratory tract Chlamydia muridarum infection, which was correlated with altered T cell cytokine profile. Furthermore, DC from C. muridarum-infected NK-depleted mice (NK−DC) exhibited a less mature phenotype compared with that of DC from the infected mice without NK depletion (NK+DC). NK−DC produced significantly lower levels of both IL-12 and IL-10 than those of NK+DC. Moreover, NK−DC showed reduced ability to direct primary and established Ag-specific Th1 CD4+ T cell responses in DC–T coculture systems. More importantly, adoptive transfer of NK−DC, in contrast to NK+DC, failed to induce type 1 protective immunity in recipients after challenge infection. Finally, NK cells showed strong direct enhancing effect on IL-12 production by DC in an NK–DC coculture system, which was partially reduced by blocking NKG2D receptors signaling and virtually abolished by neutralizing IFN-γ activity. The data demonstrate a critical role of NK cells in modulating DC function in an intracellular bacterial infection.
