Sedangkan dari semua variabel hanya variabel DER dan Inflasi yang tidak memberikan pengaruh yang signifikan terhadap variasi return saham pada taraf uji yang sama. Koefisien determinasi (122) dalam penelitian ini adalah 0 523 yang berarti bahwa 47.7 % variasi dalam return saham dipengaruhi determinan lain diluar variabel bebas yang digunakan dalam penelitian ini. Indicators like economic macro and firm financial performance had large influence towards stock return. The effect of those indicators could be positive or negative. Many investigations show that economic macro and firm financial performance indicators such inflation rate, deposit interest rate, exchange rate, EPS, PBV DER and Total Asset have a positive or negative impact towards stock return. This research intended to further examine whether firm financial performance and economic macro indicators such as inflation rate, deposit interest rate, exchange rate, EPS, PBV, DER and Total Asset influenced to stock return in Manufacture Good Sectors during period of 1999 — 2001, using multiple regression method. The samples were obtained with Purposive Sampling method from Manufacture's firm. To this end, this research employed an empirical study by using 19 issuers. The hypothesis test result showed that the data hadfulfilled classical assumptions such normally distributed, legible from otocorrelation problem, no multicollinearity and free from heteroscedasticity problem. The research showed that EPS has the strongest influence toward stock return than the other variables. In the other hand, there is no significantly influence for DER and Inflation toward variation of stock return. Coefficient of Determination (R2) is a 523, which means 47.7 % stock return variations are influenced by the free outer variables, which were used in this research.
Bottom-up fabrication of zwitterionic polymer brushes on intraocular lens for improved biocompatibility

Intraocular lens (IOL) is an efficient implantable device commonly used for treating cataracts. However, bioadhesion of bacteria or residual lens epithelial cells on the IOL surface after surgery causes postoperative complications, such as endophthalmitis or posterior capsular opacification, and leads to loss of sight again. In the present study, zwitterionic polymer brushes were fabricated on the IOL surface via bottom-up grafting procedure. The attenuated total reflection-Fourier transform infrared and contact angle measurements indicated successful surface modification, as well as excellent hydrophilicity. The coating of hydrophilic zwitterionic polymer effectively decreased the bioadhesion of lens epithelial cells or bacteria. In vivo intraocular implantation results showed good in vivo biocompatibility of zwitterionic IOL and its effectiveness against postoperative complications.
Water Politics: Governance, Conflict, and Vulnerability in Andean Peru

Peru is facing serious social and environmental water challenges. Experts and policy makers are trying to better understand the social and economic impacts of an increasing rate of glacial melt and a consequential prospect of water scarcity. Currently there is a great deal of strain put on the water resources originating from Andean glacial melt because these sustain most economic and social growth taking place at the coastal desert. At the same time, the country’s neoliberal development policies are changing the management of resources such as water. The gradual expansion of extractive industries along with the growing influence of nonstate actors is introducing new discursive representations of the environment and facilitating important changes in the spatial, administrative, and political relations of governing nature. Among the most prominent changes are the recent restructuring efforts to the Peruvian institutional and legal structure for water governance. In this context, the forms of access, control, and exploitation of water in the Andes have become more contested than ever. This thesis explores the struggle for water at Paron, one of such Andean communities. This decadelong struggle for water perfectly demonstrates how local groups, government agencies, and a private corporation negotiate their access to water. This thesis explores how organizational structures, institutional arrangements, and decision-making processes shape and are shaped by access, use, management, and regulation of water in a conflictive environment. Particularly, it analyzes how politics informs water management, and consequentially affects access to the resource. But also, given the uniqueness of this conflict, this thesis further incorporates a risk and vulnerability factor to its analysis. While this conflict comprises the socioeconomic, political, historical, cultural, and environmental components of most environmental struggles in Peru, it also presents very unique characteristics. The contested water source is managed not only for downstream water use, but also for glacial risk mitigation. As such, this thesis examines how water governance and vulnerability are co-produced in a conflictive environment. For this, I explore specific moments or instances – such as water flows and management, technology, institutions, discourses, and negotiations – that I recognize as embodying this relationship. In this analysis, I pay special attention to the impact of water technologies. I argue that a new, more convoluted, form of water politics – introduced to the watershed with hydropower technology – have created a new set of social relations that reinforce social vulnerability upon local water users, producing a transformation in vulnerability.

Lennart Sjöberg Neglecting the Risks Neglecting the Risks : The Irrationality of Health Behavior and the Quest for

The paper is a discussion of personal risk taking and risk perception in the field of health-related behavior. It reviews work on addictions, which has shown the difficulties of impulse control in the pursuit of long-term commitments. Such long-term commitments are typically in conflict with temporary and strong urges to indulge in seeking pleasure and comfort. People know and do not know, at the same time, the likely consequences of their behavior, and relapses in addictions are very common. Risk perception research has elucidated some of these points and shown that people see risks as very different for themselves and others, especially lifestyle risks. This difference is related to the notion that they can control their own risks, while others neither can, nor want to, exercise such control. Hence, own competence and motivation is overestimated, and that of other people is underestimated. Wishful thinking further contributes to irrational tendencies. Campaigns intended to change risk-taking behavior run into very difficult resistance due to these factors, and risk messages may be interpreted as pertinent to others rather than oneself.
A review of classification algorithms for EEG-based brain–computer interfaces

In this paper we review classification algorithms used to design brain–computer interface (BCI) systems based on electroencephalography (EEG). We briefly present the commonly employed algorithms and describe their critical properties. Based on the literature, we compare them in terms of performance and provide guidelines to choose the suitable classification algorithm(s) for a specific BCI.
Neural representation and identification of reaching targets by spike trains in motor cortex

Neural prostheses could help disabled patients of immobility to restore movements by exploiting brain signals. In the past decade, it has been shown great progress in intracortical neural recording techniques and neural signal processing. We review two classes of methods, population vector and maximal likelihood, for decoding the activity of primary motor cortical neurons in a nonhuman primate during center-out arm reaching movements. In particular, we show that these two methods share the same spirit of pooling activities of population of neurons but with different use of tuning function. We further compare their performance by using real neuronal data from reaching movements and inspect the effects of different parameters. It shows that maximal likelihood approach outperforms the population vector method consistently, which could be due to the more effective use of the tuning function.
An econometric investigation of the relationship between the price of oil and U.K. macroeconomic performance.

The objective of this thesis is to conduct an econometric investigation of the relationship between the price of oil and U.K. macroeconomic performance. For this purpose, quarterly seasonally-adjusted time series have been collected which extend from 1972 to 2008. Empirical results are obtained from the estimation of unrestricted and restricted vector autoregressive models. The conclusions which are reached in this study are founded upon both within- and post-sample analyses of the data. A considerable amount of research has already been devoted to the subject of the relationship between the price of oil and macroeconomic performance. Within the empirical literature, much attention has been paid to whether the macroeconomic consequences of an increase in the price of oil are symmetrical to those of a decrease. However, a largely neglected issue has been whether or not the effects of an oil price shock are subject to variation over time. The fundamental contribution which is made by this thesis is to rectify this situation through applying suitable extensions to two existing vector autoregressive models. From the empirical analysis which is subsequently undertaken, it is apparent that spurious results can arise from failing to allow for both the change in the status of the U.K. to a significant exporter of crude oil and the reduction in the intensity with which this commodity is utilised in the production process. In particular, without the recommended augmentations, the importance of past movements in the price of oil to macroeconomic performance would be seriously understated.
Management and Self-Disclosure on Social Media-A Case of Facebook Full paper

Social Media Websites are used by individuals to find new friends, (re)connect with old friends, family and relatives, maintain relationships, share information, join groups, create and manage events, pass time, and much more. While many users consistently engage in disclosing their personal information on social media, several others hold themselves back due to privacy concerns. This study employs communication privacy management theory as a theoretical framework to examine the effects of individual motives, communication privacy management practices (boundary permeability & boundary ownership) and privacy concerns on the amount and depth of self-disclosure on Facebook. Results of Partial Least Square Analysis using a sample of 240 respondents provide evidence that individuals’ communication privacy management practices influences the amount and depth of their self-disclosure. Implications for practice and future research areas are also discussed.
Polyrepresentative Clustering: A Study of Simulated User Strategies and Representations

The principle of polyrepresentation and document clustering are two established methods for Interactive Information Retrieval, which have been used separately so far. In this paper we discuss a cluster based polyrepresentation approach for information need and document based representations. In our work we simulate and evaluate two possible cluster browsing strategies a user could apply to explore the polyrepresentative clusters. In our evaluation we apply information need and bibliographic features on the iSearch collection. Our results suggest that polyrepresentative cluster browsing may be more effective than exploring a ranked list.
Antibacterial Activity of Neat Chitosan Powder and Flakes

This study investigates the antibacterial activity of neat chitosan powder and flakes against three different bacterial species, Escherichia coli, Listeria innocua and Staphylococcus aureus, which are frequent causes of food spoilage. The effect of chitosan concentration and purity, as well as the influence of temperature, ionic strength (salt) and impact of a solid physical support in the medium are examined. Results show that the antibacterial activity of neat chitosan: (i) requires partial solubilisation; (ii) can be promoted by environmental factors such as adequate temperature range, ionic strength and the presence of a solid physical support that may facilitate the attachment of bacteria; (iii) depends on bacterial species, with a sensitivity order of E. coli > L. innocua > S. aureus; and (iv) increases with chitosan concentration, up to a critical point above which this effect decreases. The latter may be due to remaining proteins in chitosan acting as nutrients for bacteria therefore limiting its antibacterial activity. These results on the direct use of chitosan powder and flakes as potential antimicrobial agents for food protection at pH values lower than the chitosan pKa (6.2–6.7) are promising.
Social Inequalities and Depressive Symptoms in Adults: The Role of Objective and Subjective Socioeconomic Status

Background There is substantial evidence that lower objective socioeconomic status (SES)—as measured by education, occupation, and income—is associated with a higher risk of depression. Less is known, however, about associations between perceptions of social status and the prevalence of depression. This study investigated associations of both objective SES and subjective social status (SSS) with depressive symptoms among adults in Germany. Methods Data were obtained from the 2013 special wave of the German Health Update study, a national health survey of the adult population in Germany. Objective SES was determined using a composite index based on education, occupation, and income. The three single dimensions of the index were also used individually. SSS was measured using the MacArthur Scale, which asks respondents to place themselves on a 10-rung ‘social ladder’. Regression models were employed to examine associations of objective SES and SSS with current depressive symptoms, as assessed with the eight-item Patient Health Questionnaire depression scale (PHQ-8 sum score ≥10). Results After mutual adjustment, lower objective SES and lower SSS were independently associated with current depressive symptoms. The associations were found in both sexes and persisted after further adjustment for sociodemographic factors, long-term chronic conditions, and functional limitations. Mediation analyses revealed a significant indirect relationship between objective SES and depressive symptoms through SSS. When the three individual dimensions of objective SES were mutually adjusted, occupation and income were independently associated with depressive symptoms. After additional adjustment for SSS, these associations attenuated but remained significant. Conclusions The findings suggest that perceptions of low social status in adults may be involved in the pathogenesis of depression and play a mediating role in the relationship between objective SES and depressive symptoms. Prospective studies are needed to establish the direction of effects and to address questions of causality.
Taylor-Couette instability of a Bingham fluid

Stability of a Bingham fluid in Taylor-Couette flow is studied. Of interest is to determine the critical values of the inner and outer cylinder angular velocities which cause the linear instability in the system. We introduce a perturbation into the basic flow, and examine the linearized Navier-Stokes equations for the perturbation. Assuming a normal mode solution for the perturbation, we obtain an eigenvalue problem which determines when the perturbation will grow or decay with time. In the case of a plug region at the outer cylinder wall, additional boundary conditions are applied at the yield surface. The marginal stability curve is generated numerically using a finite difference method. In addition to numerical analysis, heuristic arguments and energy methods are applied to find a lower bound for stability.

Review Analysis of the Association between the Prevalence of Activated Brown Adipose Tissue and Outdoor Temperature

Brown adipose tissue (BAT) is important for regulating body weight. Environmental temperature influences BAT activation. Activated BAT is identifiable using 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). 18F-FDG PET/CT scans done between June 2005 and May 2009 in our institution in tropical southern Taiwan and BAT studies from PubMed (2002–2011) were reviewed, and the average outdoor temperatures during the study periods were obtained. A simple linear regression was used to analyze the association between the prevalence of activated BAT (P) and the average outdoor temperature (T). The review analysis for 9 BAT studies (n = 16, 765) showed a significant negative correlation (r = −0.741, P = 0.022) between the prevalence of activated BAT and the average outdoor temperature. The equation of the regression line is P(%) = 6.99 − 0.20 × T (°C). The prevalence of activated BAT decreased by 1% for each 5°C increase in average outdoor temperature. In a neutral ambient temperature, the prevalence of activated BAT is low and especially rare in the tropics. There is a significant linear negative correlation between the prevalence of activated BAT and the average outdoor temperature.
The relationship between antigen concentration, antigen internalization, and antigenic complexes: modeling insights into antigen processing and presentation

Native antigen is processed and subsequently presented on the surface of antigen-presenting cells, an important step in the elicitation of an immune response. The early events of antigen processing and presentation include: ingestion of a native antigen, intracellular degradation to expose an antigenic peptide fragment, binding of this fragment with an MHC class II molecule, and display of this newly formed complex on the cell surface. Through the development of a mathematical model, a set of mathematical equations which describes the time-dependent appearance, disappearance, and movement of individual molecules, quantitative insight can be gained into the pathways and rate-limiting steps of antigen presentation. The credibility of the model has been verified by comparison to literature data. For example, it has been shown experimentally that macrophages require 60 min for effective antigen presentation, whereas B cells require 6-8 h. The mathematical model predicts these presentation times and identifies the difference in the cell's respective pinocytic rates and sizes as important parameters. B cells capture antigen in their environment through nonspecific fluid-phase pinocytosis as well as by binding antigen to their surface immunoglobulin, allowing receptor-mediated uptake. Uptake of antigen via receptor-mediated endocytosis has been reported to require 1,000-fold less antigen than uptake via nonspecific pinocytosis. The mathematical model clearly predicts this decrease in concentration. The model also makes quantitative predictions for the number of MHC class II-antigen complexes needed to produce T cell stimulation.
Minimum profile Hellinger distance estimation for a semiparametric mixture model

In this paper, we propose a new effective estimator for a class of semiparametric mixture models where one component has known distribution with possibly unknown parameters while the other component density and the mixing proportion are unknown. Such semiparametric mixture models have been often used in multiple hypothesis testing and the sequential clustering algorithm. The proposed estimator is based on the minimum profile Hellinger distance (MPHD), and its theoretical properties are investigated. In addition, we use simulation studies to illustrate the finite sample performance of the MPHD estimator and compare it with some other existing approaches. The empirical studies demonstrate that the new method outperforms existing estimators when data are generated under contamination and works comparably to existing estimators when data are not contaminated. Applications to two real data sets are also provided to illustrate the effectiveness of the new methodology. The Canadian Journal of Statistics 42: 246–267; 2014 © 2014 Statistical Society of Canada
Everolimus and Malignancy after Solid Organ Transplantation: A Clinical Update

Malignancy after solid organ transplantation remains a major cause of posttransplant mortality. The mammalian target of rapamycin (mTOR) inhibitor class of immunosuppressants exerts various antioncogenic effects, and the mTOR inhibitor everolimus is licensed for the treatment of several solid cancers. In kidney transplantation, evidence from registry studies indicates a lower rate of de novo malignancy under mTOR inhibition, with some potentially supportive data from randomized trials of everolimus. Case reports and small single-center series have suggested that switch to everolimus may be beneficial following diagnosis of posttransplant malignancy, particularly for Kaposi's sarcoma and nonmelanoma skin cancer, but prospective studies are lacking. A systematic review has shown mTOR inhibition to be associated with a significantly lower rate of hepatocellular carcinoma (HCC) recurrence versus standard calcineurin inhibitor therapy. One meta-analysis has concluded that patients with nontransplant HCC experience a low but significant survival benefit under everolimus monotherapy, so far unconfirmed in a transplant population. Data are limited in heart transplantation, although observational data and case reports have indicated that introduction of everolimus is helpful in reducing the recurrence of skin cancers. Overall, it can be concluded that, in certain settings, everolimus appears a promising option to lessen the toll of posttransplant malignancy.
