Identifying Opportunities for Future Design Research for mHealth for Mental Health

Mobile health (mHealth) improves health care by leveraging mobile technology to reach out to patients above and beyond traditional medical interventions. Unfortunately, mHealth progress is still lacking for one of the most prevalent disorders worldwide – depression. mHealth for mental health (mH) needs to deal with specific challenges such as sensitivity of patient information and traditional nature of conversation-based treatment. Nevertheless, mH has the potential to improve care through engaging patients in treatment, providing confidentiality and motivating patients to perform their “homework” in-between therapies. Our research is the first comprehensive study of mH applications for depression from one major app store. In this research paper we survey the progress of mH for depression by applying and extending a previously developed conceptual framework. We derive research opportunities for designing mHealth for mental health and analyze 124 iPhone applications for depression in order to derive the gaps in their functionality and propose actions for fuller usage of their potential. Consequently we propose a comprehensive analysis method for future design research for mHealth for mental health.
An Empirical Investigation of the Relationship between Quality Initiatives and Financial Performance

The findings of the study are: (1) majority of Turkey’s top 500 industrial enterprises implement at least one quality initiative; (2) there are significant associations between implementing quality initiatives and top 500 ranking; (3) and qualityinitiative implementing companies outperform in financial performance compared to non-quality-initiative implementing companies.
Online Feature Selection for Visual Tracking

Object tracking is one of the most important tasks in many applications of computer vision. Many tracking methods use a fixed set of features ignoring that appearance of a target object may change drastically due to intrinsic and extrinsic factors. The ability to dynamically identify discriminative features would help in handling the appearance variability by improving tracking performance. The contribution of this work is threefold. Firstly, this paper presents a collection of several modern feature selection approaches selected among filter, embedded, and wrapper methods. Secondly, we provide extensive tests regarding the classification task intended to explore the strengths and weaknesses of the proposed methods with the goal to identify the right candidates for online tracking. Finally, we show how feature selection mechanisms can be successfully employed for ranking the features used by a tracking system, maintaining high frame rates. In particular, feature selection mounted on the Adaptive Color Tracking (ACT) system operates at over 110 FPS. This work demonstrates the importance of feature selection in online and realtime applications, resulted in what is clearly a very impressive performance, our solutions improve by 3% up to 7% the baseline ACT while providing superior results compared to 29 state-of-the-art tracking methods.
Facilitating the Search for Partners on Matching Platforms

Two-sided matching platforms can control and optimize over many aspects of the search for partners. To understand how matching platforms should be designed, we introduce a dynamic two-sided search model with strategic agents who must bear a cost to discover their value for each potential partner and can do so nonsimultaneously. We characterize evolutionarily stable stationary equilibria and find that, in many settings, the platform can mitigate wasted search effort by imposing suitable restrictions on agents. In unbalanced markets, the platform should force the short side of the market to initiate contact with potential partners, by disallowing the long side from doing so. This allows the agents on the long side to exercise more choice in equilibrium. When agents are vertically differentiated, the platform can significantly improve welfare even in the limit of vanishing screening costs by forcing the shorter side of the market to propose and by hiding information about the quality of potential partners. Furthermore, a Pareto improvement in welfare is possible in this limit. This paper was accepted by Baris Ata, stochastic models and simulation.
User-Demand-Oriented Privacy-Preservation in Video Delivering

This paper presents a framework for privacy-preserving video delivery system to fulfill users' privacy demands. The proposed framework leverages the inference channels in sensitive behavior prediction and object tracking in a video surveillance system for the sequence privacy protection. For such a goal, we need to capture different pieces of evidence which are used to infer the identity. The temporal, spatial and context features are extracted from the surveillance video as the observations to perceive the privacy demands and their correlations. Taking advantage of quantifying various evidence and utility, we let users subscribe videos with a viewer-dependent pattern. We implement a prototype system for off-line and on-line requirements in two typical monitoring scenarios to construct extensive experiments. The evaluation results show that our system can efficiently satisfy users' privacy demands while saving over 25% more video information compared to traditional video privacy protection schemes.
Impact of CBR Traffic on Energy Consumption in MANET

Mobile Ad hoc networks (MANETs) are power constrained since nodes are operated with limited battery supply. If a battery of the node drains, its ability to forward the traffic gets affected results in reduced network lifetime. There has been considerable progress in the battery technology, but not in par with the semiconductor technology. There are various techniques adopt different approach to achieve energy efficiency. The proposed approach uses a cost metric for path selection, which is a function of residual battery and current traffic load at a node. The simulation has been carried out using QualNet simulator. The performance is based on average energy consumption for varying CBR applications.
Safety, efficacy and pharmacokinetics of tuftsin-loaded nystatin liposomes in murine model

Present study was performed to evaluate the efficacy, toxicity and pharmacokinetics of antifungal drug nystatin incorporated in immunomodulator tuftsin-bearing liposomes. In vitro toxicity of free nystatin and nystatin incorporated in tuftsin-free or tuftsin-loaded liposomes was assessed by incubation of nystatin formulations with human erythrocytes. The toxicity profile of free nystatin and liposomal formulations of nystatin with or without tuftsin was also analyzed by monitoring the level of blood urea nitrogen (BUN) and serum creatinine in the treated BALB/c mice. The results of the present work showed that tuftsin-loaded nystatin liposomes like conventional nystatin liposomes exerted less toxicity to human erythrocytes as compared with free nystatin. Moreover, mice treated with tuftsin-loaded nystatin liposomes showed insignificant elevation in the biochemical values of serum creatinine and blood urea. The stability of nystatin liposomes upon incorporation of tuftsin was evaluated by monitoring the leakage of the entrapped drug in human serum. Tuftsin-loaded liposomes held nystatin for longer duration in the presence of serum than identical nystatin liposomes without tuftsin. Pharmacokinetics of the both tuftsin-free or tuftsin-loaded liposomal formulations nystatin was analyzed by determining the level of nystatin in the systemic circulation of mice at different time points. Mice injected with tuftsin-loaded nystatin liposomes showed higher level of the drug in the systemic circulation compared with those treated with conventional nystatin liposomes. The efficacy of tuftsin-loaded nystatin liposomes against A. fumigatus was evaluated by assessing the fungal burden in the lungs of treated mice. Treatment with tuftsin-loaded nystatin liposomes was most effective in eliminating fungal burden from lung tissues of infected mice compared to those treated with free nystatin or nystatin liposomes without tuftsin. The immunopotentiating activity, increased stability and less toxicity of tuftsin-incorporated nystatin liposomes, supports the idea for its prophylactic and therapeutic use in the clinical setting.
Nanometric size effect on Ge diffusion in polycrystalline Si

The nanosize effect on Ge diffusion (850≤T≤1000 °C) in polycrystalline Si layers is investigated. The Ge diffusion coefficients in microcrystalline and nanocrystalline Si layers made of 30 μm and 40 nm wide grains, respectively, are measured and compared. In the microcrystalline Si layer, the Ge diffusion coefficient in micrograin boundaries is measured using a conventional analytical solution of Fick’s equations corresponding to the Fisher model. In the nanocrystalline Si layer, the Ge diffusion coefficients in nanograins and in nanograin boundaries are measured via a method based on two-dimensional simulations using the Fisher model geometry. The diffusivities in nanograins and nanograin boundaries are one order of magnitude higher than in micrograins and micrograin boundaries, respectively. However, the nanosize effect appears to be different in grains and grain boundaries; despite that the activation energy for diffusion in 40 nm wide grains is at least 1 eV lower than in Si bulk. The activation energ.
Epidemiology of smear-negative pulmonary tuberculosis in the United States, 1993-2008.

BACKGROUND Smear-negative tuberculosis (TB) is difficult to diagnose and has been associated with poor treatment outcomes and excessive mortality, particularly in high human immunodeficiency virus (HIV) prevalent settings. However, few studies have used mycobacterial culture to rigorously confirm all smear-negative TB cases in a population-based cohort. DESIGN We included all culture-confirmed, pulmonary TB cases reported to the US National TB Surveillance System from 1993 to 2008. We analyzed smear-negative TB risk factors and survival, as compared to smear-positive TB. We calculated prevalence ratios (PRs) and adjusted for confounders (aPR). RESULTS From 1993 to 2008, 159,121 cases of culture-confirmed pulmonary TB were reported in the United States, of which 58,786 (37%) were sputum smear-negative. Smear-negative TB cases were more likely to be foreign-born (aPR 1.10, 95%CI 1.08-1.12), incarcerated (aPR 1.52, 95%CI 1.48-1.56) or HIV-infected (aPR 1.27, 95%CI 1.24-1.30). Hispanics and non-Hispanic Blacks were less likely to have smear-negative TB (respectively aPR 0.87, 95%CI 0.85-0.89 and aPR 0.90, 95%CI 0.89-0.92). Smear-negative TB cases had lower mortality (aRR 0.78, 95%CI 0.74-0.81), independent of HIV status. CONCLUSION Smear-negative TB represents a large proportion of TB cases in the United States, and occurs more often among persons in groups more likely to undergo TB screening. The lower mortality may indicate earlier TB detection, and underscores the need for continued vigilance in screening of high-risk persons.
UvA-DARE ( Digital Academic Repository ) Lithium enhancement in X-ray binaries due to stellar rotation

We discuss the high lithium abundances in the secondary stars of X-ray binaries. We show that no lithium production in these stars is necessary, and that the abundances can be explained simply due to the tidally locked rotation of the stars, which lead naturally to slower lithium destruction rates. The differences in abundances of CVs’ secondaries from those of LMXBs had previously been put forth as evidence that the compact object was related to the lithium abundance, but this scenario also accounts for the lower lithium abundances in the secondary stars in cataclysmic variable systems (CVs) than in low mass X-ray binaries (LMXBs), since these stars have typically lived much longer before becoming tidally locked short period systems. We point out that if this scenario is correct, then the globular cluster X-ray binaries’ donor stars should, as a class, show less lithium enhancement relative to other stars of the same spectral type in the clusters than the field X-ray binaries donor stars show.
Prolactin inhibits apoptosis of ovarian carcinoma cells induced by serum starvation or cisplatin treatment

Prolactin, a peptide hormone essential for the development and function of reproductive organs, is involved in development of breast, prostate and colorectal cancers. However, the role of prolactin on the carcinogenesis of ovarian carcinomas is unclear. In this study, we show that mRNA of prolactin receptor is expressed in 5 out of 9 ovarian carcinoma cell lines, 15 out of 17 cases of surgical samples and all of normal ovarian surface epithelium, while prolactin transcript is detected only in 1 ovarian carcinoma cell line and in 1 of the surgical samples. For the prolactin receptor‐positive ovarian carcinoma cells, exogenous prolactin did not affect the proliferation but markedly inhibited apoptosis. Therefore, actual cell growth was enhanced by prolactin in a dose‐dependent manner. The blocking of prolactin receptor by antibody severely impaired the antiapoptotic and growth‐promoting effects of prolactin. Interestingly, the cisplatin‐induced cell death of the prolactin receptor‐positive cells was significantly inhibited by pretreatment with prolactin. These findings indicate a responsiveness of ovarian carcinomas to prolactin and suggest that the prolactin/prolactin receptor system may be a new therapeutic target of ovarian carcinomas. © 2005 Wiley‐Liss, Inc.
Vers une représentation du contexte thématique en Recherche d'Information. (Generative models of topical context for Information Retrieval)

Quand des humains cherchent des informations au sein de bases de connaissancesou de collections de documents, ils utilisent un systeme de recherche d’information(SRI) faisant office d’interface. Les utilisateurs doivent alors transmettre au SRI unerepresentation de leur besoin d’information afin que celui-ci puisse chercher des documentscontenant des informations pertinentes. De nos jours, la representation du besoind’information est constituee d’un petit ensemble de mots-cles plus souvent connu sousla denomination de « requete ». Or, quelques mots peuvent ne pas etre suffisants pourrepresenter precisement et efficacement l’etat cognitif complet d’un humain par rapporta son besoin d’information initial. Sans une certaine forme de contexte thematiquecomplementaire, le SRI peut ne pas renvoyer certains documents pertinents exprimantdes concepts n’etant pas explicitement evoques dans la requete.Dans cette these, nous explorons et proposons differentes methodes statistiques, automatiqueset non supervisees pour la representation du contexte thematique de larequete. Plus specifiquement, nous cherchons a identifier les differents concepts implicitesd’une requete formulee par un utilisateur sans qu’aucune action de sa part nesoit necessaire.

Series-connected isolated-switched-capacitor boost converter

This paper proposes novel high-step-up DC-DC converter using an isolated switched capacitor cell. The proposed converter uses the coupled-inductor, coaxial cable transformer, and switched-capacitor techniques. The output of the boost converter and isolated switched-capacitor cell are connected in series for high-step-up with a low turn-on ratio. A prototype circuit with 30-40V input voltage, 340V output voltage and 150W output power is implemented in the laboratory to verify the performance of the proposed converter.
Ethnic Disparities in Mental Health and Educational Attainment: Comparing Migrant and Native Children

Study background and aims: Ethnic disparities in mental health in adolescence may play a role in the development of ethnic disparities in educational attainment. The aim of this study was to assess the contribution of ethnic disparities in mental health problems in adolescence to ethnic disparities in educational attainment in adulthood. Methods: We followed two community samples of respectively 486 Dutch native and 168 Turkish migrant adolescents (11—15 years old) into adulthood (21—25 years old). Mental health was measured in adolescence, and educational attainment was assessed in adulthood. The contribution of mental health disparities to educational disparities was estimated by the degree of attenuation of the odds ratio (OR) for low education after adjustment for mental health problems. Results: Adult Turkish men more often had attained lower education than Dutch men (OR 1.81 (1.01—3.25)). Additional adjustment for mental health problems during adolescence did not change the OR. In Turkish women, however, the OR was 1.94 (1.04—3.62), and adjustment for mental health problems lowered it by 96% to 1.04 (0.51—2.14). The contribution was mostly due to ethnic disparities in internalizing problems. Conclusion: In women, but not in men, ethnic disparities in mental health, especially internalizing problems, were a strong predictor for the development of ethnic disparities in educational attainment. Prevention or treatment of internalizing problems among Turkish girls will probably contribute to the prevention of educational disparities.
From Digital Divide to Facebook Divide, Reconstruct Our Target Market Segments with Facebook Native and Facebook Immigrant

Digital divide emerge since early nineties when popular internet come to age. People forty-five or older than forty-five years-old are less likely to have internet access during their time as university students, and they are most likely to obtain web-based Internet related knowledge thereafter formally. The age of forty-five can be regard as the turning point age to distinguish people who may or may not have lesser knowledge on using the web-based Internet. The availability of Smartphone for the last 10 years help to increase the internet penetration rate and it also contribute to a wider digital divide. Digital immigrants and digital native are two connotations of these two groups of people. Digital native is the generation of people born into the digital age and learn through digital means, while digital immigrant is the group of people who learnt to use computers and other digital related knowledge at some stage during their adult life. With the same logical thought, 2004 was a turning point of people who acquire Facebook knowledge in school or outside school. Facebook is the number one online social network in terms of usage in most of the top fifties countries. From 2004 and onwards students who joined Facebook are Facebook natives, while people who join and acquire Facebook skills outside collage and thereafter are Facebook immigrants. The two groups of people plus those who did not have access to Facebook constitute the situation of Facebook divide society. Facebook native and Facebook immigrant are the two major market segments,which marketers are dealing with in current years. Facebook is the largest online social network and similar online social networks may dominant in different societies where society is divided as well. Secondary data on internet usage, Facebook usage, Facebook ranking, and participate observation on Facebook group & pages are applied for analysis. Reconstruct our target market segments shall be in place.
Improvement of the essence of professional judgment in accounting of Ukraine

The article analyzes the approaches to defining the essence of professional judgment on the basis of international and Ukrainian legislation in the field of accounting. Classification of scientific approaches for judgment of an accountant is defined, in particular: situational, targeted and professional. The main aim of the article is to provide practical recommendations on the author's definition of the essence of the professional judgment of an accountant and its implementation in the Law of Ukraine «On Accounting and Financial Reporting in Ukraine» and National Accounting Standards. Using the methods of induction and deduction, analysis and synthesis, the method of consistency, the article proposes, under the professional judgment of an accountant, to understand the formed judgment in the conditions of uncertainty based on the professional knowledge and skills of the accountant, which is proposed in the absence of a legislative and normative document that will describe the accounting methodology of the corresponding accounting object, the availability of methodological alternatives for its management or direct indication of the application of such judgment in the formation of credibility reporting that will be used by stakeholders to make informed decisions.
Inhibition of p21‐mediated ROS accumulation can rescue p21‐induced senescence

The cyclin‐dependent kinase (CDK) inhibitor p21Waf1/Cip1/Sdi1 was identified initially as a gene induced in senescent cells and itself has been shown to cause permanent growth arrest/senescence. Reactive oxygen species (ROS), a byproduct of oxidative processes, can also induce an irreversible growth arrest similar to senescence. Here we show that p21 increased intracellular levels of ROS both in normal fibroblasts and in p53‐negative cancer cells. N‐acetyl‐L‐cysteine, an ROS inhibitor, rescued p21‐induced senescence, showing that ROS elevation is necessary for induction of the permanent growth arrest phenotype. p16Ink4a, a CDK4‐ and CDK6‐specific inhibitor, failed to increase ROS levels, and cell cycle arrest induced by p16 was reversible following its down‐regulation, demonstrating the specificity of this p21 effect. A p21 mutant that lacked the ability to bind proliferating cell nuclear antigen (PCNA) retained the ability to induce both ROS and permanent growth arrest. All of these findings establish that p21 mediates senescence by a mechanism involving ROS accumulation which does not require either its PCNA binding or the CDK inhibitory functions shared with p16.
Who Seeks Financial Advice?

The determinants of seeking five types of financial advice are examined and are found to be consistent across the different types of advice. In addition, no significant differences are found among subsamples defined by gender, age, and financial literacy. Income and risk tolerance are related positively to the demand for financial advice and more greatly affect the probability of seeking advice than do other variables. A low perception of financial knowledge, which can be a proxy for self-confidence, and financial fragility decrease the probability of seeking financial advice.
