Wage Rigidity, Collective Bargaining, and the Minimum Wage: Evidence from French Agreement Data
Authors: Avouyi-Dovi Sanvi , Fougère Denis , Gautier Erwan 
Published: October 2012

AbstractUsing data sets on wage agreements at both industry and firm levels in France, we document stylized facts on wage stickiness. The average duration of wages is a little less than one year, and 10% of wages are modified each month by a wage agreement. The frequency of wage change agreements is staggered over the year, but the frequency of effective wage changes is seasonal. The national minimum wage has a significant impact on the probability and the seasonality of wage changes. Negotiated wage increases are correlated with inflation, minimum wage increases, and firm profitability.
Organizational Form and Performance: Evidence from the Hotel Industry
Authors: Kosová Renáta , Lafontaine Francine , Perrigot Rozenn 
Published: October 2012

Abstract
We use a unique proprietary panel data set from a large hotel company to study how organizational form affects hotel pricing and performance. Aggregate data patterns suggest sizable performance differences between franchised and company-operated hotels. However, after controlling for other factors, we find that if significant at all, such differences are economically small. Moreover, once we endogenize the choice of organizational form, the differences become insignificant. We conclude that the company chooses which hotels to franchise and operate corporately such that, conditional on hotel and market characteristics, it obtains consistent outcomes across organizational forms.
The Effect of Gasoline Prices on Household Location
Authors: Molloy Raven , Shan Hui 
Published: October 2012

Abstract
By raising commuting costs, an increase in gasoline prices should reduce the demand for housing in areas far from employment centers relative to locations closer to jobs. Using annual panel data on a large number of postal codes and municipalities from 1981 to 2008, we find that a 10% increase in gas prices leads to a 10% decrease in construction in locations with a long average commute relative to other locations but to no significant change in house prices. Thus, the supply response prevents the change in housing demand from capitalizing in house prices.
Do Product Market Regulations in Upstream Sectors Curb Productivity Growth? Panel Data Evidence For OECD Countries

Published: October 2012

Abstract
We identify the impact of intermediate goods markets imperfections on productivity downstream. Our empirical specification is based on a model of multifactor productivity (MFP) growth in which the effects of upstream competition can vary with distance to frontier. This model is estimated on a panel of fifteen OECD countries and twenty industries over 1985 to 2007. Competitive pressures are proxied with industry product market regulation data. We find evidence that anticompetitive upstream regulations have significantly curbed MFP growth over the past fifteen years, and more strongly so for observations that are close to the productivity frontier.
The Impact of Charitable Subsidies on Religious Giving and Attendance: Evidence from Panel Data
Authors: Yörük Barış K. 
Published: October 2012

Abstract
The literature documents that charitable giving is responsive to tax subsidies but often ignores the spillover effects of such policies. This paper investigates the spillover effects of charitable subsidies on religious participation using individual-level panel data. The results show that religious giving and participation are complements. The implied cross-price elasticity of religious participation with respect to the after-tax price of giving is −0.27. Furthermore, a 1% increase in the amount of religious contributions is associated with a 0.4% increase in religious attendance. These results are robust under several different specifications and highlight the positive externalities created by charitable subsidies.

Objective: This study used a sample of Korean adolescents to evaluate: (a) associations between problematic internet use and depression, bipolar disorder symptoms and suicidal ideation; and (b) whether mood disorders mediate the relationship between problematic internet use and suicidal ideation. Method: A total of 795 middle and high school students were recruited (538 girls; mean age, 13.87 ± 1.51 years). The Internet Addiction Proneness Scale for Youth–Short Form (KS-scale) was used to evaluate the presence and severity of problematic internet use. The frequencies of depression, suicidal ideation and probable bipolar disorder were compared between adolescents with and without internet addiction. The associations between the severity of problematic internet use and the severity of depressive symptoms, bipolar symptoms and suicidal ideation were also analyzed. Results: Seventy-five adolescents (9.4%) met the criteria for problematic internet use. The presence of problematic internet use was significantly associated with suicidal ideation (OR = 5.82, 95% CI = 3.30–10.26, p < 0.001) as well as depression (OR = 5.00, 95% CI = 2.88–8.66, p < 0.001). There was a marginally significant association between problematic internet use and probable bipolar disorder (OR = 3.05, 95% CI = 0.96–9.69, p = 0.059). In the path model, problematic internet use significantly predicted depressive symptoms (β = 0.296, 95% CI = 0.214–0.367, p = 0.005), which predicted suicidal ideation (β = 0.699, 95% CI = 0.631–0.751, p = 0.009). Problematic internet use also predicted suicidal ideation directly (β = 0.115, 95% CI = 0.052–0.193, p = 0.006). Conversely, depressive symptoms (β = 0.119, 95% CI = −0.005–0.219, p = 0.040) and suicidal ideation (β = 0.215, 95% CI = 0.089–0.346, p = 0.005) predicted problematic internet use. Conclusions: There is a complex transactional relationship between problematic internet use, depressive symptoms, bipolar symptoms and suicidal ideation, so these conditions must be assessed together during the evaluation of adolescents. Prospective studies are warranted to elucidate the causal relationships between problematic internet use, mood symptoms and suicidal ideation.
The presentation of early-onset psychotic disorders
Authors: Starling Jean , Williams Leanne M , Hainsworth Cassandra , Harris Anthony W 
Published: October 2012

Objective: This study aims to describe the clinical course of psychotic disorders, including the premorbid history, symptoms and level of functioning in a group of children and adolescents treated by paediatric mental health services, mainly as inpatients. Method: A sample of 45 children and adolescents with a psychotic disorder (mean age 13.2 years) was assessed using questionnaires, semi-structured interviews, parent interviews and file audit. The symptoms of those with a schizophrenia spectrum disorder (SSD) were compared to those with a mood disorder (MD). Results: This population showed a high level of premorbid impairment, including previous treatment for other psychiatric disorders. As well as hallucinations and delusions, high levels of self-harm, aggression, anxiety and depression were reported. The SSD and MD groups differed mainly in their levels of premorbid functioning. Conclusions: While it is well known that childhood-onset schizophrenia is a severe disorder with a poor outcome, this study found that young people diagnosed with other psychotic disorders also have significant impairment and are likely to require high levels of care to maximize their functional recovery.
Forensic Memory, Responsibility, and Judgment
Authors: Pino-Ojeda Walescka 
Published: October 2012

Among the political documentaries produced in Chile in the postauthoritarian era there is a significant corpus of films that carry out a meticulous process of forensic memory. Both documentaries that dig through skeletal remains and those that excavate the memories of surviving victims or witnesses of state terror are carrying out similar archaeological forensic work. They examine records that, rather than simply evidencing past violence, exhibit the fractures (subjective and discursive) from which the past may be reconstructed. By focusing on these tasks the films La ciudad de los fotógrafos (Sebastián Moreno, 2007), El juez y el general (Elizabeth Farnsworth and Patricio Lanfranco, 2008), and El diario de Agustín (Ignacio Agüero, 2008) become media for reflection that makes it possible for viewers to confront their own history—in order to make ethical judgments that allow them to assume personal and collective responsibility in the face of a history that they have lived or have assimilated through a process of “post-memory.” To the question posed by Arendt—whether thinking can help to correct and eradicate acts of radical evil—we could respond that postauthoritarian Chilean documentary finds itself dealing precisely with this possibility through accounts that, by means of personal experience and sifting through one’s own biographical ruins, call on spectators to delve into their own fears and complicities. Dentro de los innumerables documentales políticos producidos en Chile en el período postautoritario, hay un corpus significativo que ha llevado a cabo un cuidadoso trabajo memorial-forense. Tanto aquellos documentales que hurgan en las reliquias óseas como los que escarban en las memorias de víctimas sobrevivientes o testigos del terror de Estado llevan a cabo un trabajo arqueológico forense. Escrutan registros en que, más que dar cuenta de la violencia de los hechos mismos, exhiben la fractura (subjetiva-discursiva) desde donde se reconstruye dicho pasado. Para tal contexto, los filmes La ciudad de los fotógrafos (Sebastián Moreno, 2007), El juez y el general (Elizabeth Farnsworth y Patricio Lanfranco, 2008), y El diario de Agustín (Ignacio Agüero, 2008) se constituyen en espacios de reflexión para hacer posible que el espectador encare su propia historia, elabore un juicio ético que le permita asumir una responsabilidad personal y colectiva frente a una historia que ha vivido biográficamente o que ha asimilado a través de la transmisión postgeneracional, vía un proceso de “post-memoria.” A la interrogante planteada por Arendt—¿puede el ejercicio de pensar ayudar a corregir y erradicar los actos de maldad radical?—podríamos responder que el cine documental chileno postautoritario se encuentra precisamente abordando esta posibilidad a través de relatos que, mediante experiencias personales y atravesando las propias ruinas biográficas, interpelan al espectador para adentrarse en sus propios lastres, miedos y complicidades.
The Influence of Age on the Effectiveness of Neuromuscular Training to Reduce Anterior Cruciate Ligament Injury in Female Athletes
Authors: Myer Gregory D. , Sugimoto Dai , Thomas Staci , Hewett Timothy E. 
Published: October 2012

Background: In female athletes, sports-related injuries to the anterior cruciate ligament (ACL) increase during adolescence and peak in incidence during the mid- to late teens. Although biomechanical investigations indicate that a potential window of opportunity exists for optimal timing for the initiation of integrative neuromuscular training (NMT) in young female athletes, the influence of the timing of initiation of these programs on the efficacy of ACL injury reduction has yet to be evaluated. Hypothesis/Purpose: The purpose of the current report was to systematically review and synthesize the scientific literature regarding the influence of age of NMT implementation on the effectiveness for reduction of ACL injury incidence. The hypothesis tested was that NMT would show a greater effect in younger populations. Study Design: Meta-analysis; Level of evidence 1a. Methods: Data were pooled from 14 clinical trials that met the inclusion criteria of (1) number of ACL injuries reported; (2) NMT program used; (3) female participants were included; (4) investigations used prospective, controlled trials; and (5) age of participants was documented or was obtainable upon contact with the authors. A meta-analysis with odds ratio (OR) was used to compare the ratios of ACL injuries between intervention and control groups among differing age categorizations. Results: A meta-analysis of the 14 included studies demonstrated significantly greater knee injury reduction in female athletes who were categorized in the preventive NMT group compared with those who were in the control group (OR: 0.54; 95% confidence interval [CI]: 0.35, 0.83). Lower ACL injuries in mid-teens (OR 0.28; CI: 0.18, 0.42) compared with late teens (OR 0.48; CI: 0.21, 1.07) and early adults (OR 1.01; CI: 0.62, 1.64) were found in participants undergoing NMT. Conclusion: The findings of this meta-analysis revealed an age-related association between NMT implementation and reduction of ACL incidence. Both biomechanical and the current epidemiological data indicate that the potential window of opportunity for optimized ACL injury risk reduction may be before the onset of neuromuscular deficits and peak knee injury incidence in female athletes. Specifically, it may be optimal to initiate integrative NMT programs during early adolescence, before the period of altered mechanics that increase injury risk.

This study aimed to investigate the protective effect of selenium (Se) on methimazole (MMI; an antithyroid drug)-induced hepatotoxicity in adult rats and their progeny. Female Wistar rats were randomly divided into four groups of six rats in each group: group I served as controls that received standard diet; group II received MMI in drinking water as 250 mg L−1 and standard diet; group III received both MMI (250 mg L−1, orally) and Se (0.5 mg kg−1 of diet); group IV received Se (0.5 mg kg−1 of diet) as sodium selenite. Treatments were started from the 14th day of pregnancy until day 14 after delivery. Exposure of rats to MMI promoted oxidative stress with an increase in liver malondialdehyde levels, advanced oxidation protein products and protein carbonyl contents and a decrease in the levels of glutathione, nonprotein thiols and vitamin C. A decrease in the activities of liver glutathione peroxidase, superoxide dismutase, catalase and lactate dehydrogenase and in the levels of plasma total protein and albumin was also observed. Plasma transaminase activities and total, direct and indirect bilirubin levels increased. Coadministration of Se through diet improved all biochemical parameters. The histopathological changes confirmed the biochemical results. Therefore, our investigation revealed that Se, a trace element with antioxidant properties, was effective in preventing MMI-induced liver damage.

Published: October 2012

There is an increasing need for synthetic bone substitute materials that decrease the need for allografts and autografts. In this study, composites of β-tricalcium phosphate and a biodegradable poly(L-lactide-co-ɛ-caprolactone) were manufactured using extrusion to form biodegradable composites with high β-tricalcium phosphate contents for osteoconductivity. The hydrolytic degradation of the composites containing 0, 10, 20, 35 and 50% of β-tricalcium phosphate was studied in vitro for 52 weeks. During the study, it was observed that β-tricalcium phosphate did not have an effect on the degradation rate of the polymer matrix. However, the crystallinity of the materials increased throughout the test series and changes in glass transition temperatures were also observed as the comonomer ratio of the polymer matrix changed as the degradation proceeded. The results show that the materials have desirable degradation properties and, thus, possess great potential as bioabsorbable and osteoconductive bone filling materials.
Polyurethane–magnetite composite shape-memory polymer
Authors: Weidenfeller Bernd , Anhalt Mathias 
Published: October 2012

Shape-memory polymer–magnetite (Fe3O4) composite samples were prepared by extrusion compounding and injection molding. Thermal diffusivity, conductivity and specific heat capacity were measured from 290 K to 340 K. Increasing filler fraction decreases specific heat capacity and increases thermal diffusivity. Experimental results show a good agreement with Agari–Uno and Hashin–Shtrikman models but not with Bruggeman model. The interconnectivity of the particles is very poor. Agari–Uno model leads to a high influence of polymer on thermal properties. Below 350 K mainly the polymer and above 350 K mainly the Fe3O4 influences specific heat capacity that shows drastic changes around 310 K (recovery temperature) and 357 K.

Authors: Madhavaiah C. , Bashir Irfan , Shafi Syed Irfan 
Published: October 2012

Cloud computing is an emerging innovative IT-based business model which is attracting the attention of practitioners, for its potentiality of industry adoption, as well as of academicians, for research undertaking in different dimensions. Despite having a number of business benefits and research scope, there is no universally accepted comprehensive, conceptual definition for cloud computing. Though different experts and academicians have given different definitions to cloud computing, none of them have identified all the key characteristics of cloud computing.  The purpose of the present article is to analyze the various definitions of cloud computing proposed by different researchers and practitioners, using content analysis methodology, and establish areas of ‘agreement’ and to construct such a ‘general’ definition of cloud computing in business perspective. This article is divided into three sections. In the first section, content analysis methodology used on cloud computing definitions is presented. The second section highlights the key words in 36 definitions of cloud computing and tabulates the definitions through a categorization of ‘substantive terms’. The last section discusses the results of research methodology followed by conclusion and limitations.

Authors: Lee Young Ho , Choi Sung Jae , Ji Jong Dae , Song Gwan Gyu 
Published: October 2012

Objective: The aim of this study was to determine whether the insertion (I) /deletion (D) polymorphism within intron 16 of angiotensin-converting enzyme ( ACE) confers susceptibility to systemic lupus erythematosus (SLE) and lupus nephritis (LN). Methods: A meta-analysis was conducted on the associations between the ACE I/D polymorphism and SLE and LN. Results: A total of 1907 patients with SLE and 1842 controls in 18 comparative studies were included in this meta-analysis. The analysis showed a significant association between SLE and the DD genotype (recessive effect) of the ACE polymorphism (odds ratio [OR] 1.383, 95% confidence interval [CI] 1.065–1.797, p = 0.015). Stratification by ethnicity indicated a marginal association between the DD genotype and SLE in Europeans (OR 1.210, 95% CI 0.964–1.519, p = 0.099; I2 = 0%). Meta-analysis also revealed a trend toward to an association between SLE and the ACE polymorphism using the allelic or additive models in Europeans. Furthermore, meta-analysis of the DD+ID genotype showed a significant association with LN (OR 0.582, 95% CI 0.425–0.797, p = 0.001; I2 = 0%). Conclusion: This meta-analysis demonstrates a strong association between DD genotype and SLE in overall study and a marginal association between SLE and the ACE D/I polymorphism in Europeans, and suggests that this polymorphism might confer susceptibility to LN.
Aortic Augmentation Index is Independently Associated With N-Terminal Pro B-type Natriuretic Peptide in Patients With Peripheral Arterial Disease
Authors: Shahin Yousef , Chetter Ian 
Published: October 2012

Objectives: To investigate the relationship of aortic augmentation index (AIx) with N-terminal pro B-type natriuretic peptide (NTproBNP) plasma levels in patients with peripheral arterial disease (PAD) with normal left ventricular (LV) function. Methods: Totally, 31 patients (23 males, mean age 65 ± 7.4) with a confirmed diagnosis of PAD of the lower limbs (ankle–brachial pressure index [ABPI] <0.90 in at least 1 leg) were enrolled in this study. All patients underwent pulse wave analysis by applanation tonometry of the radial artery using the SphygmoCor system and had a measurement of plasma NTproBNP levels. Results: Patients had a mean resting ABPI of 0.62 ± 0.19 and a mean AIx 32.6% ± 6.9. Median (interquartile range) NTproBNP plasma level was 75 (44-210) pg/mL. In a univariate analysis which included age, brachial systolic blood pressure (BSBP), brachial diastolic blood pressure (BDBP), ejection duration index (ED%), heart rate (HR), and NTproBNP, aortic AIx was significantly associated (Spearman rho) with NTproBNP, HR, and ED% ( r = .49, P = .006; r = −.72, P = .000, and r = −.42, P = .02, respectively). Multivariate linear regression analysis showed that AIx was associated with NTproBNP (β = 0.38, P = .02) independent of gender, HR, ED%, and use of β-blockers. N-terminal pro B-type natriuretic peptide explained 8% of the variance in aortic AIx, whereas HR explained 15% of the variance. Conclusion: In patients with PAD with normal LV systolic function, AIx is independently associated with NTproBNP. Structural changes in the myocardium might occur due to increased LV afterload as a result of increased wave reflections and arterial stiffness due to atherosclerosis leading to an increase in NTproBNP plasma levels.
Arterial Reconstruction for Atypical Mycotic Aneurysms
Authors: Malinowski Michael J. , Halandras Pegge 
Published: October 2012

Our case involves a 67-year-old man with a post lung transplantation status for idiopathic pulmonary fibrosis, who was initially referred to our institution for treatment of left hip septic arthritis due to Pseudallescheria boydii infection. One month following total hip arthroplasty, he noticed left upper thigh swelling with duplex imaging consistent with a 7-cm mid-superficial femoral artery aneurysm with popliteal vein compression and associated deep venous thrombosis. During operative resection, exploration of his contralateral saphenous vein showed inadequate conduit for use. Therefore, we proceeded with proximal and distal clamp control with intraoperative arterial shunting followed by cryoarterial reconstruction after complete aneurysm sac resection and debridement. Intraoperative arterial wall cultures remained negative for bacterial pathogens; however, final operative fungal cultures once again grew Pseudallescheria boydii. Our case highlights the complexity of adequate source control with effective arterial reconstruction in these immunosuppressed patient populations, particularly with fungal organisms that historically have poor therapeutic response to medical therapy alone.
