The Performance of Unemployment Rate Predictions in Romania. Strategies to Improve the Forecasts Accuracy
Authors: Simionescu Mihaela 
Published: January 2014

AbstractThe evaluation and improvement of forecasts accuracy generate growth in the quality of decisional process. In Romania, the most accurate predictions for the unemployment rate on the forecasting horizon 2001-2012 were provided by the Institute for Economic Forecasting (IEF) that is followed by European Commission and National Commission for Prognosis (NCP). The result is based on U1, but if more indicators are taken into consideration at the same time using the multi-criteria ranking, the conclusion remains the same. A suitable strategy for improving the degree of accuracy for these forecasts is represented by the combined forecasts. The accuracy of NCP predictions can be improved on the horizon 2001-2012, if the initial values are smoothed using Holt-Winters technique and Hodrick-Prescott filter. The use of Monte Carlo method to simulate the forecasted unemployment rate proved to be the best way to improve the predictions accuracy. Starting from an AR(1) model for the interest variable, the uncertainty analysis was included, the simulations being made for the parameters. Actually, the means of the forecasts distributions for unemployment are considered as point predictions which outperform the expectations of the three institutions. The strategy based on Monte Carlo method is an original contribution of the author introduced in this article regarding the empirical strategies of getting better predictions.

An analysis of the possibility of intersystem transformations for purposes of geo-referencing old mine workings
Authors: Staňková Hana , Černota Pavel , Novosad Miroslav 
Published: January 2014

Abstract
The paper is dedicated to the issues of both planar and spatial transformations with respect to the territory affected by mining activities. The planar transformations have been applied among the planar Otto mine coordinate system, St. Stephen Datum of Cadastre Coordinates, and the Datum of Uniform Trigonometric Cadastral Network (hereinafter referred to as JTSK). Here basic transformation characteristics among the above systems are defined. The spatial transformation is performed through a point coordinate conversion between the JTSK and the European Terrestrial Reference System (hereinafter referred to as ETRS89) where conventional relations as well as other conversion possibilities were described. Part of the article is the execution of an experiment of a direct transformation between the St. Stephen Datum of Cadastre Coordinates and the ETRS98 system for the territory of Brno, which was not affected by mining activities. For the above transformation, 8 trigonometric points were used, for which the identity analysis had been done initially. Furthermore, the Interpolation and One Step Transformations were tested, which solve the conversion as divided tasks for both position and heights. The Interpolation Transformation showed better values for residues. The results of the above experiment will be applied for purposes of surveying old mine workings using the GNSS technology.
Effect of calcination temperature and calcination time on the kaolinite/tio2 composite for photocatalytic reduction of CO2
Authors: Reli Martin , Kočí Kamila , Matějka Vlastimil , Kovář Pavel , Obalová Lucie 
Published: January 2014

Abstract
The kaolinite/TiO2 composite (60 wt% of TiO2) was prepared by thermal hydrolysis of a raw kaolin suspension in titanyl sulphate and calcined at different temperatures (600, 650 and 700°C) and for different times (1, 2 and 3 h). The obtained samples were characterized by XRPD, N2 physical adsorption and SEM, and tested for photocatalytic reduction of CO2. The different calcination conditions did not influence TiO2 phase composition, only slightly changed the specific surface area, and significantly affected crystallite size of kaolinite/TiO2 composite. A higher temperature and longer duration of calcination lead to higher crystallinity of the powder. The photocatalytic results showed that the crystallite size determined the efficiency of kaolinite/TiO2 photocatalysts.
NOGI IZOLDY MORGAN, CZYLI KOBIETY I TRAMWAJE / BRUNON JASIEŃSKI’S IZOLDA MORGAN’S LEGS, OR WOMEN AND TRAMS
Authors: Alksnin Adrianna 
Published: January 2014

Summary
This article presents a psychoanalytical reading of Brunon Jasieński’s Izolda Morgan’s Legs. The main character of this micro novel is driven by a fetishistic fascination with the amputated legs of his mistress. Yet his feelings of fear and desire seem to be a reaction to a broader set of circumstances. Mr Berg, an engineer, is deeply upset not only by the progress of women’s emancipation but also the creeping mechanization of everyday life. The latter is connected with the advances of industrialization and the growing dependence of the individual on the products of modern technology. In effect man gets alienated from social life and gradually less able to preserve his sanity.

From Lagoon to Sea : When the Bream Pass

In Sète, from late August till mid-November, people fish for bream. Since this fish is caught along quays or canals, this activity, which cyclically mobilizes knowledge and know-how, reveals the meeting of two types of geographical space : sea and pool. This invites us to explore the connections between three recurrent themes : sea, lagoon and city. This ethnographic investigation of bream-fishing sheds light on a seldom encountered sociability. Given this activity's invariability and constant repetition, a hypothesis is made about its ritualization. Sea, canal and pool are types of space found all around the edge of the
Mediterranean and along parts of the Atlantic shore. By constantly resuming the sea/lagoon dialogue, these coastal zones occupy a central position in shaping the cultural universe of lagoon societies along the seashore.

Published: January 2014

ABSTRACT
Objective: To clinically investigate the antibacterial effects of a commercially available self-etch 12-methacryloyloxy- dodecylpyridinium bromide (MDPB)-containing adhesive system in comparison with its respective non-MDPB-containing adhesive and to evaluate the pulp responses when in use on human teeth. Materials and Methods: Sixty-two viable human teeth scheduled for extraction were used. Class V cavities were prepared on the buccal surfaces of the teeth and filled with the tested materials (Protect Bond/Clearfil AP-X, SE Bond/Clearfil AP-X and Dycal/Ketac Fill Plus) as a control group, according to manufacturer′s recommendations. Randomly divided to two groups teeth remained intra-orally for 4 and 8 weeks. After extraction, teeth were decalcified, sectioned and stained using the Mayer′s hematoxylin and eosin, and modified Brown-Brenn′s technique. Pulp responses were evaluated microscopically under a microscope and remaining dentine thickness measured under a stereomicroscope. Results: No statistically significant differences regarding pulp inflammation or bacterial infiltration were found either for the materials tested or for periods of post-operative evaluation. Conclusions: The results suggested that for a short period of evaluation there are no quantitative differences, regardless to restoring material used.

Published: January 2014

ABSTRACT
Objective: An appliance was designed to increase the cortical bone surface contact area of miniscrew implants (MSIs). The purpose of this in vitro study was to evaluate the effects of this appliance on the anchorage force resistance and the stability of orthodontic MSIs. Materials and Methods: A total of 48 MSIs were placed into bone specimens prepared from the ilium of bovines. Half were placed with the newly designed apparatus and half were placed conventionally. All the specimens were subjected to tangential force loading perpendicular to the MSI with lateral displacement of 0.6 mm, using an Instron Universal Testing machine. The maximum removal torque of each tested specimen was also recorded. Both study and control groups were divided into two subgroups based on whether they had thin and thick cortical bone. Results: The test group had statistically higher force anchorage resistance and maximum insertion torque values than the control group (p < 0.001). The results were found to be more significant in cases in which the cortical bone was thin (p < 0.001). Conclusions: Within the limits of this in vitro study, the present findings suggest that the newly designed apparatus might have a favorable effect on MSI stability in patients presenting with thin cortical bone. Clinical studies are necessary to confirm the results that were observed in vitro.
Investigation of third molar impaction in Turkish orthodontic patients: Prevalence, depth and angular positions
Authors: Topkara Ahu , Sari Zafer 
Published: January 2014

ABSTRACT
Objective: We aimed to investigate the prevalence, distribution, angular position, and depth of third molar impaction in a Turkish orthodontic patient population. Materials and Methods: We retrospectively reviewed the panoramic radiographs, intraoral photographs, and dental casts of 207 patients (62 men and 145 women; age 20-39 years) who had undergone orthodontic treatment at a university department of orthodontics for impacted third molars (ITMs). A comprehensive chart review of all subjects was conducted. Patient and treatment-related data were recorded in a digital database for comparative analysis. Results: The prevalence of ITMs was 54.1%, and no statistically significant gender differences were evident (61.3% in men and 51.0% in women; P = 0.23). The frequency of maxillary ITMs was 49.3% (148 of 300 teeth) while that of mandibular ITMs was 50.7% (152 of 300 teeth). The most frequently observed angulations of impaction were mesioangular for the mandible (65.1%), and distoangular for the maxilla (64.2%). Of all the ITMs analysed, 61% were partially buried in bone and 39% were completely buried. Conclusions: Third molar impaction was evident in 54.1% of a group of Turkish orthodontic patients aged 20-39 years, and there was no statistically significant gender bias. Mesioangular and distoangular inclinations were the most common in the mandible and the maxilla, respectively.
Geoffrey's Credo:
Authors: Burrow John 
Published: January 2014

Abstract
When Geoffrey denies any desire for “fame,” he may mean either that he is content to live a private, unnoticed life or that he does not look for glory as a poet. The latter meaning is suggested by his enigmatic reference to “myn art,” and Alexander Pope took it so in The Temple of Fame, his version of Chaucer's Book III.
Industry Competition and Earnings Persistence:Empirical Tests Based on Real Options Theory1
Authors: Chen Xinyuan , Jin Qinglu , Xiao Tusheng 
Published: January 2014

Abstract
Using A-share listed companies in China from 1999 to 2010, this paper investigates the influence of industry competition on earnings persistence from the perspective of the real options theory. Different from the traditional industrial economics theory, analyses based on the real options theory show that the influence of industry competition on earnings persistence may be nonlinear and that the relationship between the two may vary with the firm’s operating efficiency or profitability. Our empirical results show that for companies with low profitability, intense industry competition can encourage management to exercise abandonment options more effectively, thereby reducing the persistence of earnings; in contrast, for companies with high profitability, intense industry competition can encourage management to exercise growth options more effectively and offset the mean reverting effect, thus increasing the persistence of earnings. Additional tests illustrate that the influence of industry competition on earnings persistence is also reflected in the relationship between stock price changes and earnings changes, that is, the earnings response coefficient. Overall, this paper suggests that the influence of industry competition on the execution of real options is reflected in the earnings pattern
Venture Capital, Property Rights, and Managerial Compensation Contracts1
Authors: Xue Shuang , Tang Fengshou 
Published: January 2014

Abstract
This paper investigates the impact of venture capital on managers’ compensation contracts. The results show that pay-performance sensitivity (PPS) is higher in venture-capital-backed companies than in non-venture-capital-backed companies. A higher PPS may bring managers of venture-capital-backed companies a higher extra emolument compared with that offered by other companies in the same industry. A further test shows that the positive effect of venture capital on PPS and extra emolument exists in (1) private enterprises rather than state-owned enterprises (SOEs) and (2) in firms backed by highly reputable venture capitalists (VCs) rather than in firms backed by VCs with a low reputation. The findings indicate that even after initial public offerings (IPOs), venture capital still has a positive impact on corporate governance and affects managerial compensation contracts.
Fast stratocumulus time scale in mixed layer model and large eddy simulation
Authors: Jones C. R. , Bretherton C. S. , Blossey P. N. 
Published: January 2014

AbstractA mixed layer model (MLM) and large eddy simulation (LES) are used to analyze the internal response time scales of a stratocumulus‐topped boundary layer (STBL). Three separate time scales are identified: a slow time scale associated with boundary layer deepening (several days), an intermediate thermodynamic time scale (approximately 1 day), and a fast time scale (6–12 h) for cloud water path adjustment associated with an internal entrainment‐liquid flux (ELF) feedback. The nocturnal DYCOMSII‐RF01 case study is used to establish and interpret the previously unidentified fast STBL adjustment time scale with the MLM. The role of the entrainment closure is investigated by repeating the analysis with several different closures. Nearly every closure considered exhibits a fast time scale. Perturbations are applied to the well‐mixed CGILS stratocumulus case in both MLM and LES in order to elicit a short time scale response. Purely radiative perturbations do not project strongly onto the fast scale, while perturbations to the free tropospheric humidity do. A 2K surface and atmospheric temperature perturbation also projects strongly onto the fast scale. We show that the ELF adjustment mechanism behind the fast time scale is responsible for much of the steady state liquid water path response in the perturbed case, acting as a cloud‐thinning feedback mechanism in a uniformly warmed climate.

ObjectiveSleep disturbances frequently accompany chronic pain from osteoarthritis (OA). Effective management of sleep disturbances may require successful treatment of chronic pain, a key factor in the clinical evaluation of knee OA. However, the relationship between the severity of knee OA and sleep quality is unclear. Our purpose was to correlate the prevalence of nocturnal knee pain with different OA severity levels and to determine its influence on sleep quality.MethodsSubjects included 1,214 local volunteers with mean ± SD age 58.1 ± 13.0 years. The existence and severity of knee OA were determined by the Kellgren/Lawrence (K/L) grade, and joint space widths were measured. The presence of nocturnal knee pain and Knee Injury and Osteoarthritis Outcome Scores (KOOS) were assessed by self‐completed questionnaires. Sleep quality was evaluated by the Pittsburgh Sleep Quality Index. Knee‐related factors affecting sleep quality were detected using statistical methods.ResultsThe prevalence of nocturnal knee pain was 3.6%, 6.9%, 19.4%, 32.7%, and 75.0% in K/L grades 0, 1, 2, 3, and 4, respectively. Also, prevalence significantly increased with OA severity (P < 0.001). Sleep problems also increased with K/L grade (P = 0.038), and KOOS quality of life (QOL) was significantly lower in those with OA and sleep problems. Logistic regression showed that sleep problems were related to joint space narrowing (P = 0.016) and nocturnal knee pain (P = 0.039). Severe OA also disturbed onset and maintenance of sleep.ConclusionThe prevalence of nocturnal knee pain and sleep problems increased with the severity of OA, impacting QOL. These results suggest the necessity of appropriate nocturnal pain control.

Published: January 2014

ObjectiveTo investigate lifetime risk of total hip replacement (THR) surgery in the state of Victoria, Australia and to describe temporal trends in THR incidence.MethodsWe analyzed a retrospective population‐based longitudinal cohort of patients who received a primary THR in Victoria from 1998–2009. The factors potentially contributing to changes in lifetime risk were also examined, including temporal changes in THR incidence according to health care setting (public versus private), socioeconomic status, and geographic location (regional versus metropolitan).ResultsWe identified 45,775 patients receiving THR over the time period. For a woman age 20–29 years, the mortality‐adjusted lifetime risk rose significantly over time, from 8.49% (95% confidence interval [95% CI] 8.23–8.69%) in 1999–2000 to 10.30% (95% CI 10.07–10.49%) in 2007–2008. For a man age 20–29 years, the mortality‐adjusted lifetime risk also increased significantly, from 9.29% (95% CI 8.97–9.58%) in 1999–2000 to 10.27% (95% CI 9.95–10.48%) in 2004–2005, but in contrast to the pattern observed for women, it decreased slightly in 2007–2008 (9.90% [95% CI 9.60–10.16%]). We also identified an increasing number of THRs in private hospitals, in people in middle and low socioeconomic groups, and in rural areas.ConclusionThe lifetime risk of THR for women was similar to men, despite a higher burden of hip osteoarthritis, and this warrants further investigation. However, increases in the number of THR procedures performed for patients in regional areas and in lower socioeconomic groups suggest some reductions over time in known disparities.

ObjectiveAn association between 25‐hydroxyvitamin D (25[OH]D; vitamin D) deficiency and increased cardiovascular (CV) risk factors and CV disease (CVD) has been shown in general population studies. Vitamin D deficiency has been noted in systemic lupus erythematosus (SLE), and CVD is a major cause of morbidity and mortality in SLE. The objectives of this study were to estimate the associations of 25(OH)D levels with CV risk factors and to determine whether low baseline 25(OH)D levels predict future CV events in patients participating in an international inception cohort.MethodsData were collected on 890 participants, including demographics, SLE activity and damage assessments, CV risk factors and events, medications, laboratory assessments of 25(OH)D levels, and inflammatory markers. Multiple logistic and Cox regressions were used to estimate the associations of baseline 25(OH)D levels with baseline CV risk factors and CVD events. The models were adjusted for age, sex, race, season, and country, with and without body mass index.ResultsPatients in the higher quartiles of 25(OH)D were less likely to have hypertension and hyperlipidemia and were more likely to have lower C‐reactive protein levels and lower Systemic Lupus Erythematosus Disease Activity Index 2000 scores at baseline when compared with the first quartile. Vitamin D levels were not independently associated with CVD event incidence; however, hazard ratios for CVD event incidence decreased with successively higher quartiles.ConclusionLower baseline 25(OH)D levels are associated with higher risk for CV risk factors and more active SLE at baseline. There may be a trend toward a lower likelihood of CVD events in those with higher baseline 25(OH)D levels.
