Analysis of Bone Tissue Healing around Titanium Implant Surface Treated with Tio Sandblasted after Three and Six Weeks Used Different Histological Methods - a Study in Rabbits

Objective: The aim of this study was to observe the in vivo cellular reaction and calcium deposition around dental implants after applying three histological techniques. Methods: Six adult New Zealand rabbits, with an average weight of 3.5 kg, were included. Twenty-four cylindrical implants with an internal hex were used in the experiment. The implants were sandblasted with titanium micro- particles and then were conditioned with maleic acid. Calcein was injected subcutaneously at two different time points to assess calcium deposition on the bone - at the first and second weeks in examination group 1 (exam1); and at fourth and fifth weeks in examination group 2 (exam2) - with three animals in each group. Each implant was cut into 3 slices, and each slice was used for a different histological technique: one for light microscopy, one for fluorescence, and one for scanning. The samples were analysed and compared with the reactions at the interface of the bone and implant after 3 and 6 weeks. Results: The results demonstrated different reactions in bone tissue being observed at the time corresponding to the exam1 group, mainly intense cellular proliferation and bone matrix production. The exam2 group demonstrated organisation and the maturation of the newly form tissue. The clinical significance is that, under appropriate conditions, restorative procedures may begin after 6 weeks. Conclusion: The implants showed large corticalised areas, and they featured lamellar bone after 6 weeks. Calcium deposition occurred with greater intensity between the 3th and 6th weeks after implantation.
Impact of Business Process Re-engineering on the Performance of Banksin Pakistan

The purpose of this study is to observe those factors which can affect the performance of banks in Pakistan due to business process reengineering BPR. This study has also tried to discuss the execution of business process reengineering (BPR) in the financial institutions of Pakistan. Pilot test was conducted to measure the test. SPSS is used to analyze the gathered information of banks. The results demonstrate that the dimensions of BPR are reliable and valid. The results are significant and execution of BPR was also found in various operations processes in the Banks of Pakistan.
Outperformance and Tracking: Dynamic Asset Allocation for Active and Passive Portfolio Management

ABSTRACT Portfolio management problems are often divided into two types: active and passive, where the objective is to outperform and track a preselected benchmark, respectively. Here, we formulate and solve a dynamic asset allocation problem that combines these two objectives in a unified framework. We look to maximize the expected growth rate differential between the wealth of the investor’s portfolio and that of a performance benchmark while penalizing risk-weighted deviations from a given tracking portfolio. Using stochastic control techniques, we provide explicit closed-form expressions for the optimal allocation and we show how the optimal strategy can be related to the growth optimal portfolio. The admissible benchmarks encompass the class of functionally generated portfolios (FGPs), which include the market portfolio, as the only requirement is that they depend only on the prevailing asset values. Finally, some numerical experiments are presented to illustrate the risk–reward profile of the optimal allocation.
SHORT GAS DISSIPATION TIMESCALES: DISKLESS STARS IN TAURUS AND CHAMAELEON I

We present an Advanced Camera for Surveys/Solar Blind Channel far-ultraviolet (FUV) study of H2 gas in 12 weak T Tauri stars in nearby star-forming regions. The sample consists of sources which have no evidence of inner disk dust. Our new FUV spectra show that in addition to the dust, the gas is depleted from the inner disk. This sample is combined with a larger FUV sample of accretors and non-accretors with ages between 1 and 100 Myr, showing that as early as 1–3 Myr, systems both with and without gas are found. Possible mechanisms for depleting gas quickly include viscous evolution, planet formation, and photoevaporation by stellar radiation fields. Since these mechanisms alone cannot account for the lack of gas at 1–3 Myr, it is likely that the initial conditions (e.g., initial disk mass or core angular momentum) contribute to the variety of disks observed at any age. We estimate the angular momentum of a cloud needed for most of the mass to fall very close to the central object and compare this to models of the expected distribution of angular momenta. Up to 20% of cloud cores have low enough angular momenta to form disks with the mass close to the star, which would then accrete quickly; this percentage is similar to the fraction of diskless stars in the youngest star-forming regions. With our sample, we characterize the chromospheric contribution to the FUV luminosity and find that LFUV/Lbol saturates at ∼10−4.1.
Children’s Caring Roles and Responsibilities within the Family in Africa

In many Sub-Saharan African countries, the care of chronically ill, disabled or elderly relatives is usually regarded as the responsibility of family members, within a broader landscape of often overburdened healthcare systems, the expense of medical fees, very limited access to social protection and policies that emphasise home-based care. Recent studies have demonstrated that children and youth, particularly girls and young women, take on considerable caring roles for chronically ill and elderly and young relatives in Africa. This article reviews the available research on young people’s caring roles and responsibilities within families affected by chronic illness and disability in Sub-Saharan Africa. I discuss how children’s caring roles challenge global and local constructions of childhood and suggest ways of conceptualising the socio-spatial and embodied dimensions of children’s everyday care work within diverse household forms. I analyse evidence on outcomes of caring and children’s resilience in managing their caring responsibilities and examine the complex array of processes that influence whether children take on caring roles within the family. I argue that relational, intergenerational and lifecourse approaches to researching children’s caring responsibilities within the family have considerable potential for future geographical research and could provide further insights into the ways that care is embedded in social relationships, cultural norms and structural inequalities operating in different configurations in particular places.
Religious Styles Predict Interreligious Prejudice: A Study of German Adolescents with the Religious Schema Scale

Based on a sample of 340 German adolescents age 12 to 25, this article presents an analysis of the effects of religion on two instances of interreligious prejudice: anti-Islamic and anti-Semitic prejudice. Reflecting the emergent interest in implementing a perspective of religious maturity and religious development into research on religion and prejudice, the present study has included the Religious Schema Scale (RSS) which, with its three subscales, Truth of Texts & Teachings (ttt), Fairness, Tolerance & Rational Choice (ftr), and Xenosophia/Interreligious Dialog (xenos), differentiates religious styles. Regression analyses indicate the superior explanatory power of the RSS in comparison to other measures of religiosity. The RSS subscale ttt relates to and predicts anti-Islamic and anti-Semitic prejudice, whereas ftr and xenos relate to and predict disagreement with interreligious prejudice. Results of an analysis of variance using high agreement on ttt, ftr, and xenos for group construction indicate a decrease in interreligious prejudice in relation to religious development.
Discourse structure and language

An increasing number of researchers and practitioners in Natural Language Engineering face the prospect of having to work with entire texts, rather than individual sentences. While it is clear that text must have useful structure, its nature may be less clear, making it more difficult to exploit in applications. This survey of work on discourse structure thus provides a primer on the bases of which discourse is structured along with some of their formal properties. It then lays out the current state-of-the-art with respect to algorithms for recognizing these different structures, and how these algorithms are currently being used in Language Technology applications. After identifying resources that should prove useful in improving algorithm performance across a range of languages, we conclude by speculating on future discourse structure-enabled technology.
DISPERSION CONTROL FOR MULTIVARIATE PROCESSES

Summary This paper presents some techniques for monitoring and controlling the dispersion of multivariate normal processes based on subgroup data. The procedures involve use of independent statistics resulting from the decomposition of the covariance matrix. Those that do not depend on prior estimates of the process covariance matrix are particularly attractive to short-run or low volume manufacturing environments.
Evaluation and diversity analysis in Indian mustard [Brassica juncea (L.) Czern & Coss.] germplasm accessions on the basis of principal component analysis

Principal component analysis was carried out with 20 morphological traits (including quantitative as well as qualitative) among 96 germplasm lines of Indian mustard [Brassica juncea (L.) Czern & Coss. ]. Principal factor analysis led to the identification of eight principal components (PCs) which explained about 70.41% variability. The first principal component (PC1) explained 16.21% of the total variation. The remaining PC’s explained progressively lesser and lesser of the total variation. Varimax Rotation enabled loading of similar type of variables on a common principal factor (PF) permitting to designate them as yield factor, maturity factor and oil factor etc. Based on PF scores and cluster mean values the germplasm accessions viz., RC2, RC32 and RC51 (cluster I), RC95 and RC96 (cluster X) were found superior for seed yield/plant and yield related factors like primary and secondary branches/plant; while the accessions RC34, RC185 and RC195 (cluster III) and RC53 (cluster VIII) were found superior for oil content. These accessions may further be utilized in breeding programmes for evolving mustard varieties having high seed yield and oil content. Hierarchical cluster analysis resulted into ten clusters containing two to 26 accessions. The results of cluster and principal factor analyses were in confirmation of each other.
Research challenges and findings from a driver training pilot study in China

The George Institute in Australia and China collaborated on a pilot study, funded by the FIA Foundation, to develop and evaluate a driver education and training program to reduce novice driver crashes in China. The program was established and implemented in Beijing during 2010-2011. A randomised control trial was conducted with recently licensed drivers recruited through official driving schools. Block randomisation was used to randomise participants to the intervention (n=64) or control group (n=63), with the latter receiving roadside assistance memberships to similar monetary value as the intervention. The intervention included a DVD education program on novice-specific risks plus six hours of in-vehicle training focused on maintaining a safety gap around the vehicle. Participants completed baseline and follow-up questionnaires at approximately four months apart. Recruitment proved challenging, however, once involved, all participants bar one continued through to follow-up. Relatively equal distribution by age, gender and other characteristics was achieved. Very low incidence of any risk taking was reported. Trained participants were significantly more likely to transition to driving-related employment positions and also, but not significantly, reported greater average driving exposure, driving risks and inflated perceptions of their ability than controls. There was no difference in crash involvement (9 participants or 14 per cent in each group). Findings may reflect cultural differences in research familiarity and reporting as much as actual outcomes of the intervention; notwithstanding limitations in participant numbers and self-reported methods applied. The potential for the program to lead to over-calibration and increased risk cannot be discounted. More effort is needed in future studies to build rapport with participants and to have local endorsements to support truthful responding without consequences. Representative research and more local data on novice crash and offence issues is also needed to increase our understanding of novice driver risks in China and how to best address them.

The outcomes and cost data that are available varies greatly between fields. This review examines the history of robotic surgery, the advantages and disadvantages of this technology followed by the applications of robotic surgery in the fields of: urology, gynecology, pediatric surgery and general surgery. Finally, the cost data from the fields of urology and pediatric surgery are reviewed and used to create a model to evaluate the financial impact of a surgical robot on a hospital.
The VIPERS Multi-Lambda Survey. II. Diving with massive galaxies in 22 square degrees since z = 1.5

We investigate the evolution of the galaxy stellar mass function and stellar mass density from redshift z = 0.2 to z = 1.5 of a K-s \textless 22-selected sample with highly reliable photometric redshifts and over an unprecedentedly large area. Our study is based on near-infrared observations carried out with the WIRCam instrument at CFHT over the footprint of the VIPERS spectroscopic survey and benefits from the high-quality optical photometry from the CFHTLS and ultraviolet observations with the GALEX satellite. The accuracy of our photometric redshifts is sigma(Delta/(1+z)) \textless 0.03 and 0.05 for the bright (i(AB) \textless 22.5) and faint (i(AB) \textgreater 22.5) samples, respectively. The galaxy stellar mass function is measured with similar to 760 000 galaxies down to K-s similar to 22 and over an effective area of similar to 22.4 deg(2), the latter of which drastically reduces the statistical uncertainties (i.e. Poissonian error and cosmic variance). We point out the importance of carefully controlling the photometric calibration, whose effect becomes quickly dominant when statistical uncertainties are reduced, which will be a major issue for future cosmological surveys with EUCLID or LSST, for instance. By exploring the rest-frame (NUV-r) vs. (r-K-s) colour-colour diagram with which we separated star-forming and quiescent galaxies, (1) we find that the density of very massive log(M*/M-circle dot) \textgreater 11.5 galaxies is largely dominated by quiescent galaxies and increases by a factor 2 from z similar to 1 to z similar to 0.2, which allows for additional mass assembly through dry mergers. (2) We also confirm the scenario in which star formation activity is impeded above a stellar mass log(M*(sf)/M-circle dot) = 10.64 +/- 0.01. This value is found to be very stable at 0.2 \textless z \textless 1.5. (3) We discuss the existence of a main quenching channel that is followed by massive star-forming galaxies, and we finally (4) characterise another quenching mechanism that is required to explain the clear excess of low-mass quiescent galaxies that is observed at low redshift.
Peak-load pricing in public transport: a case study of Stockholm

This paper studies how the price affects the demand for public transport in the peak- and off-peak period in the public transport in Stockholm. Further, the study investigates how differences in price elasticities of demand in the peak- and off-peak period can enable an increase in revenues as well as the total number of passengers while dampening the peak-load problem through price discrimination. The data is set up to examine the effect of the price on the number of passengers travelling by subway from January 1999 to December 2008. A number of control variables are used to isolate the effect of a price change in our econometric model. Thereafter, the elasticities of demand for each period are calculated in order to find Ramsey prices that can be used when a monopoly firm maximizes profit and minimizes the welfare loss. The study concludes that the price elasticities of demand differ between the peak- and the off-peak period and that SL should charge a higher price in the peak-period and a lower price in the off-peak period to both increase their revenue, the total number of passengers, and reduce their problems associated with the peak-load demand.
Too smart to be selfish? Measures of intelligence, social preferences, and consistency

Although there is an increasing interest in examining the relationship between cognitive ability and economic behavior, less is known about the relationship between cognitive ability and social preferences. We investigate the relationship between strongly incentivized measures of intelligence and measures of social preferences. We have data on a series of small-stakes dictator-type decisions, known as Social Value Orientation (SVO), in addition to choices in a larger-stakes dictator game. We also have access to the grade point averages (GPA) and Scholastic Aptitude Test (SAT) outcomes of our subjects. We find that subjects who perform better on the math portion of the SAT are more generous in both the dictator game and the SVO measure. By contrast we find that subjects with a higher GPA are more selfish in the dictator game and more generous according to the SVO. We also find that the consistency of the subjects is related to GPA but we do not find evidence that it is related to either portion of the SAT.
Does workplace partnership deliver mutual gains at work?

This article uses a large matched employer–employee dataset to assess the outcomes of workplace partnership for British firms and workers, and the HR practices associated with ‘mutual gains’. The findings suggest that HR practices which promote employee voice and participation can deliver mutual gains for both employees and employers, but that it is the combination of direct and indirect participation which appears to be most useful in generating superior outcomes for all stakeholders. However, some practices such as high levels of job flexibility and team briefing procedures are found to be negatively associated with work-related attitudes and/or organizational performance.

SELF-CONCEPT DURING THE FIRST GRADE 2

This study examined to what extent parents’ and teachers’ beliefs about children’s abilities predict children’s self-concept of math and reading ability development during the first grade, and whether these predictions depend on the child’s gender and level of performance. One hundred fifty-two children and their parents and teachers were followed across first grade. The results showed, first, that the associations between teachers’ beliefs and children’s subsequent self-concept of ability depended on the level of the children’s performance. Among high-performers, the higher the teachers’ beliefs about their students’ abilities in reading or in math, the higher the subsequent level of self-concept of ability. Among low-performers no association was found between teachers’ beliefs and students’ selfconcept of ability in either reading or math. Second, mothers’ and fathers’ beliefs were not predictive of children’s self-concept of math and reading ability during first grade. Overall, these results suggest that during the first grade it is teachers’ rather than parents’ beliefs, that play a role in children’s selfconcept of ability. In teacher education, emphasis should therefore be placed on the importance of supporting children’s developing self-concept as well as teaching new academic skills.
User feedback integration - incremental improvement

Keyword search systems became very popular in the last decade because they allow people to access and find information in an easy and comfortable way. However, to keep the Quality of these systems on a high level, the system designers have to address several problems like changing requirements of the users or changes in the underlying data structure. We believe that user feedback is an elegant way to handle some of these problems and keep the system flexible and adaptable for future changes in the requirements. To prove this concept this report explains the design and implementation of several user feedback features which are added to an existing keyword search system over data warehouses. We will show by example how these features can be used by the users and how they improve the usability and flexibility of the given system. At the end of this report we will show proposals for other feedback features and how the implemented features could be further improved.
