A CLOUD DEPLOYMENT APPROACH FOR CONSUMER SUPPORT SYSTEMS

Customer relationships have been commonly recognized as a critical factor for enterprises to succeed their business. Effective customer relationships could help enterprises deliver services to customers based on their needs, preferences, or past transactions. This model however emphasizes on the use of customer information for benefiting enterprises; customers in contrast receive less information from enterprises. To address this issue, the paradigm Consumer Support Systems (CSS) is proposed to support the provision of service information for customers to help on their decision making. In addition, since Cloud Computing has been popularity for its rich set of features and their practical applications on business can be expected, it is thus an envisioned trend for CSS to be deployed on clouds to enhance further its effectiveness on customer relationships. For this need, we present in this paper a cloud deployment approach for such a cloud-based CSS. The approach starts from the consideration of CSS and cloud characteristics, through the recognition of the architectural components in CSS and clouds, and finally ends with the deployment of the architectural components in CSS on clouds. The approach is illustrated by a cloud-based CSS for travel arrangement where decision support for travels is provided for satisfying the arrangement needs from travelers

The Graph Database: Jack of All Trades or Just Not SQL?

This special issue of IT Professional focuses on the graph database. The graph database, a relatively new phenomenon, is well suited to the burgeoning information era in which we are increasingly becoming immersed. Here, the guest editors briefly explain how a graph database works, its relation to the relational database management system (RDBMS), and its quantitative and qualitative pros and cons, including how graph databases can be harnessed in a hybrid environment. They also survey the excellent articles submitted for this special issue

In vivo microdialysis reveals age-dependent decrease of brain interstitial fluid tau levels in P301S human tau transgenic mice

Although tau is a cytoplasmic protein, it is also found in brain extracellular fluids, e.g., CSF. Recent findings suggest that aggregated tau can be transferred between cells and extracellular tau aggregates might mediate spread of tau pathology. Despite these data, details of whether tau is normally released into the brain interstitial fluid (ISF), its concentration in ISF in relation to CSF, and whether ISF tau is influenced by its aggregation are unknown. To address these issues, we developed a microdialysis technique to analyze monomeric ISF tau levels within the hippocampus of awake, freely moving mice. We detected tau in ISF of wild-type mice, suggesting that tau is released in the absence of neurodegeneration. ISF tau was significantly higher than CSF tau and their concentrations were not significantly correlated. Using P301S human tau transgenic mice (P301S tg mice), we found that ISF tau is fivefold higher than endogenous murine tau, consistent with its elevated levels of expression. However, following the onset of tau aggregation, monomeric ISF tau decreased markedly. Biochemical analysis demonstrated that soluble tau in brain homogenates decreased along with the deposition of insoluble tau. Tau fibrils injected into the hippocampus decreased ISF tau, suggesting that extracellular tau is in equilibrium with extracellular or intracellular tau aggregates. This technique should facilitate further studies of tau secretion, spread of tau pathology, the effects of different disease states on ISF tau, and the efficacy of experimental treatments

Health of Philippine Emigrants Study (HoPES): study design and rationale.

BackgroundImmigrants to the United States are usually healthier than their U.S.-born counterparts, yet the health of immigrants declines with duration of stay in the U.S. This pattern is often seen for numerous health problems such as obesity, and is usually attributed to acculturation (the adoption of "American" behaviors and norms). However, an alternative explanation is secular trends, given that rates of obesity have been rising globally. Few studies of immigrants are designed to distinguish the effects of acculturation versus secular trends, in part because most studies of immigrants are cross-sectional, lack baseline data prior to migration, and do not have a comparison group of non-migrants in the country of origin. This paper describes the Health of Philippine Emigrants Study (HoPES), a study designed to address many of these limitations.MethodsHoPES is a dual-cohort, longitudinal, transnational study. The first cohort consisted of Filipinos migrating to the United States (n = 832). The second cohort consisted of non-migrant Filipinos who planned to remain in the Philippines (n = 805). Baseline data were collected from both cohorts in 2017 in the Philippines, with follow-up data collection planned over 3 years in either the U.S. for the migrant cohort or the Philippines for the non-migrant cohort. At baseline, interviewers administered semi-structured questionnaires that assessed demographic characteristics, diet, physical activity, stress, and immigration experiences. Interviewers also measured weight, height, waist and hip circumferences, blood pressure, and collected dried blood spot samples.DiscussionMigrants enrolled in the study appear to be representative of recent Filipino migrants to the U.S. Additionally, migrant and non-migrant study participants are comparable on several characteristics that we attempted to balance at baseline, including age, gender, and education. HoPES is a unique study that approximates a natural experiment from which to study the effects of immigration on obesity and other health problems. A number of innovative methodological strategies were pursued to expand the boundaries of current immigrant health research. Key to accomplishing this research was investment in building collaborative relationships with stakeholders across the U.S. and the Philippines with shared interest in the health of migrants

Positive Criminology and Rethinking the Response to Adolescent Addiction: Evidence on the Role of Social Support, Religiosity, and Service to Others

Adolescent addiction has emerged as a major public health problem. The greatest increase in alcohol and other drug use disorders can be found among youth. Concurrently, technological advances in policing coupled with aggressive prosecuting and sentencing practices have contributed to the growth of America’s correctional system. The assertive response of policing, courts, and corrections, however, have not prevented the dramatic rise of adolescent addiction. Unfortunately, there is no national data tracking addicted youth in the criminal justice system to evaluate what works when it comes to youth with addiction. This article reviews justice system responses to adolescent offenders with addiction, and promising approaches engaging juveniles in programmatic components of Alcoholics Anonymous (AA). This study highlights the role of spirituality, service to others, and social support in maintaining sobriety, reducing arrests, and lowering recidivism for adolescents court-referred to treatment. Recommendations for improving the response to adolescent offenders with addiction are offered

Buspirone for the treatment of dementia with behavioral disturbance

Behavioral disturbances are common but serious symptoms in patients with dementia. Currently there are no FDA approved drugs for this purpose. There have been case reports and small case series of the use of buspirone. In this retrospective study, we review 179 patients prescribed buspirone for treatment of behavioral disturbance in dementia to better characterize the efficacy and potential side effects. All patients prescribed buspirone for behavioral disturbance due to dementia from a geropsychiatric outreach program were reviewed. Data was collected and analyzed using SPSS. One hundred-seventy-nine patients met criteria for the study with a mean age of 83.8 + 7. Alzheimer’s dementia was the most common dementia (n=111; 62%) followed by vascular type (n=81; 45.5%). Behavioral disturbances were mainly verbal aggression (n= 125; 72.3%), and physical aggression (n=116; 47.5%). Using the Clinical Global Impression scale, 72.8% of patients responded to buspirone, with 30.8% being moderately to markedly improved. The mean dose of buspirone was 25.7 mg ±12.50. Buspirone appears to be effective in treating behavioral disturbances in dementia. Future prospective and double blinded studies are needed
