Mobile Application Security Platforms Survey

Nowadays Smartphone and other mobile devices have become incredibly important in every aspect of our life. Because they have practically offered same capabilities as desktop workstations as well as come to be powerful in terms of CPU (Central processing Unit), Storage and installing numerous applications. Therefore, Security is considered as an important factor in wireless communication technologies, particularly in a wireless ad-hoc network and mobile operating systems. Moreover, based on increasing the range of mobile application within variety of platforms, security is regarded as on the most valuable and considerable debate in terms of issues, trustees, reliabilities and accuracy. This paper aims to introduce a consolidated report of thriving security on mobile application platforms and providing knowledge of vital threats to the users and enterprises. Furthermore, in this paper, various techniques as well as methods for security measurements, analysis and prioritization within the peak of mobile platforms will be presented. Additionally, increases understanding and awareness of security on mobile application platforms to avoid detection, forensics and countermeasures used by the operating systems. Finally, this study also discusses security extensions for popular mobile platforms and analysis for a survey within a recent research in the area of mobile platform security

Scaling Capitalist Class Relations: Commercial Property Development in Tampa, Florida

We test the relationship between the implied cost of capital and two agency problems, free cash flows and overinvestment. We show that free cash flows have a significant negative impact on the implied cost of capital, but overinvestment has a significantly positive impact. In addition, the pay-for-performance sensitivity has a negative effect but the sensitivity of volatility has a significantly positive effect on the implied cost of capital. After taking the incentives into account, we find that the significance of the impact from both agency problems still exists. Finally, we conclude that well-designed executive compensation should focus on reducing overinvestment and the sensitivity of volatility

Healthcare Data Governance, Privacy, and Security -- A Conceptual Framework

The abundance of data has transformed the world in every aspect. It has become the core element in decision making, problem solving, and innovation in almost all areas of life, including business, science, healthcare, education, and many others. Despite all these advances, privacy and security remain critical concerns of the healthcare industry. It is important to note that healthcare data can also be a liability if it is not managed correctly. This data mismanagement can have severe consequences for patients and healthcare organisations, including patient safety, legal liability, damage to reputation, financial loss, and operational inefficiency. Healthcare organisations must comply with a range of regulations to protect patient data. We perform a classification of data governance elements or components in a manner that thoroughly assesses the healthcare data chain from a privacy and security standpoint. After deeply analysing the existing literature, we propose a conceptual privacy and security driven healthcare data governance framework

Data Behind the Walls An Advanced Architecture for Data Privacy Management

In today's highly connected society, we are constantly asked to provide personal information to retailers, voter surveys, medical professionals, and other data collection efforts. The collected data is stored in large data warehouses. Organisations and statistical agencies share and use this data to facilitate research in public health, economics, sociology, etc. However, this data contains sensitive information about individuals, which can result in identity theft, financial loss, stress and depression, embarrassment, abuse, etc. Therefore, one must ensure rigorous management of individuals' privacy. We propose, an advanced data privacy management architecture composed of three layers. The data management layer consists of de-identification and anonymisation, the access management layer for re-enforcing data access based on the concepts of Role-Based Access Control and the Chinese Wall Security Policy, and the roles layer for regulating different users. The proposed system architecture is validated on healthcare datasets.Comment: 7 page

Trauma and mental health in Pacific Islanders

BackgroundLittle is known about trauma and its mental health impact on Native Hawaiians/Pacific Islanders (NH/PI), an understudied Indigenous-colonized population that endures severe mental health disparities.AimsThis novel investigation assessed trauma prevalence and its mental health and substance use correlates in NH/PIs in the U.S.MethodUsing community-based participatory research methods, survey data on NH/PI trauma, depression, anxiety, substance use, and treatment need were collected from 306 NH/PI adults using online, telephone, and in-person methods. Descriptive statistics and adjusted regression models were employed.ResultsSixty-nine percent of participants experienced lifetime trauma, reporting mean exposure to 2.5 different trauma types. Childhood physical and sexual abuse, and lifetime forced sexual assault rates were 34%, 25%, and 27%, respectively, exceeding general population rates. Women and men reported equivalent total mean exposure to different trauma types, as well as equal prevalence for every trauma type examined (e.g. sexual abuse/assault). Confirming hypotheses, after controlling for key demographic and mental health risk factors, increased exposure to multiple trauma types uniquely associated with greater depression, anxiety, alcohol symptomology, and greater likelihood for needing treatment and using illicit substances.ConclusionsTrauma is prevalent in NH/PI populations and significantly impacts NH/PI mental health; serving as an important but overlooked contributor to NH/PI mental health disparities. Current findings fill critical gaps in our knowledge of NH/PI trauma and mental health while revealing the importance of screening and treating NH/PIs for trauma exposure to alleviate existing mental health disparities

Cardiac, Hepatic and Renal Dysfunction and IL-18 Polymorphism in Breast, Colorectal, and Prostate Cancer Patients

Introduction: The present study aimed to determine the alterations in the serum levels of tumor markers used to evaluate cardiac, renal and liver function, and detect the interleukin (IL)-18 rs1946518 polymorphism in breast (BC), colorectal (CRC) and prostate cancer (PCa) patients. Methods: Blood samples were collected from 65 female BC, 116 CRC, 79 PCa and 88 myocardial infarction (MI) patients, and 110 healthy individuals to determine the concentration of tumor and cardiac markers. Furthermore, the IL-18 rs1946518 polymorphism was assessed using amplification refractory mutation system (ARMS)-PCR. Results: The serum levels of the tumor markers cancer antigen 15-3 (CA 15-3), carbohydrate antigen 19-9 (CA 19-9), carcinoembryonic antigen (CEA) and total prostate-specific antigen (TPSA) were significantly increased in cancer patients compared with healthy controls. Furthermore, the activity of high-sensitivity cardiac troponin T (hs-cTnT) and creatine kinase‑myocardial band (CK-MB) was enhanced in MI patients, however, their activity was unchanged in cancer patients. The activity of alkaline phosphatase (ALP), and the serum concentration of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and urea were markedly elevated in CRC and PCa patients, respectively, compared with the control group. Although, no significant differences were observed in the -607 C/A polymorphism and allele frequency of IL-18 among BC, CRC patients and healthy individuals, the odds ratio (OR) was 1.75 for both C and A allele in BC patients. Therefore, the -607 C/A polymorphism could be considered as a risk factor for BC. Conclusion: The aforementioned results suggested that tumor markers could be considered as excellent biomarkers for the early detection of BC, CRC and PCa, whereas the concentration of liver enzymes could serve as an alternative indicator for the diagnosis of CRC and PCa. Additionally, the rs1946518 polymorphism in the IL-18 gene could be considered as a risk factor for the occurrence of BC, CRC and PCa

Checklist of the Pleistocene marine molluscs of Praínha and Lagoínhas (Santa Maria Island, Azores).

A critical review of the reported Pleistocene species of and Lagoinhas (Santa Maria Island, Azores) is provided, new data increasing the marine molluscan fauna to 95 taxa (80 Gastropoda and 15 Bivalvia). Six of the reported taxa are considered dubious records (5 Gastropoda, 1 Bivalvia). The stratigraphic sequence of Praia Formosa is composed of two main units, about 2-4 meters above present-day sea level. In the lower unit, Patella ulyssiponensis dominates the fossil assemblage of the basal calcareous conglomerate while Myoforceps arustatus (Dillwyn, 1817) dominates the assemblage associated to a calcareous algae mat. Above a non-depositional hiatus surface, a sandy beach deposit mainly composes the upper unit. Its fossil assemblages are dominated by large amounts of Eruilin castanea (Montagu, 1803) and, in a less extent, Lucinella diwricntn (Linnaeus, 1758) and Ensis minor (Chenu, 1843). The stratigraphic sequence of Lagoinhas, located 7.4 m above present-day sea level, is also composed of two units. A basal conglomerate is fossilized by or passes laterally to a calcareous algae mat, dominated by Myoforceps aristatus and with abundant Calliostoma pecimens. As at Prainha, these lower units are covered by a highly fossiliferous sandy bach deposit, though thinner, in which Ervlie castanea is the dominant species. Some species with Caribbean or West African affinities, the "Strombus bubonius accompanying fauna" (Garcia-Talavera, 1990), were found in the lower layers. The upper layer malacofauna is mainly related to the Mediterranean faunas, similarly to what happens nowadays (Ávila, 2000)
