Security Architecture for Tanzania Higher Learning Institutions’ Data Warehouse
In this paper we developed security architecture for the higher learning institutions in Tanzania which considers security measures to be taken at different level of the higher learning institutions’ data warehouse architecture. The primary objectives of the study was to identify security requirements of the higher learning institutions data warehouses and then study the existing security systems in and finally develop and architecture based on the requirements extracted from the study. The study was carried at three different universities in Tanzania by carrying out interviews, study of the existing systems in respective institutions and a literature review of the existing data warehouses systems and architectures. The result was the security requirements identified which lead to the development of the security architecture comprising security in source systems, data, and services to be offered by the DW, applications which use DW, networks and other physical infrastructure focusing on security controls like authentication, role-based access control, role separation of privileged users, storage of data, secure transfer of data, protective monitoring/ intrusion detection, penetration testing, trusted/secure endpoints and physical protection. Keywords: Data warehouse, security architecture, higher learning institution
Predictive Behavior of a Computational Foot/Ankle Model through Artificial Neural Networks
Computational models are useful tools to study the biomechanics of human joints. Their predictive performance is heavily dependent on bony anatomy and soft tissue properties. Imaging data provides anatomical requirements while approximate tissue properties are implemented from literature data, when available. We sought to improve the predictive capability of a computational foot/ankle model by optimizing its ligament stiffness inputs using feedforward and radial basis function neural networks. While the former demonstrated better performance than the latter per mean square error, both networks provided reasonable stiffness predictions for implementation into the computational model

The household economy : examining the mediating roles of income diversification and home production on economic and subjective well-being of women in Malawi
An integrated framework of Family Resource Management and Household
Economic theory was utilized to develop a model of relationships between
human capital, family characteristics and resources, number of income
sources, hours spent in home production, total income and subjective well-being.
This study utilized a sample of 129 women systematically selected
from Machinga and Zomba Districts in Malawi.
Results of Path analysis showed that place of residence, primary
education and secondary education or above had positive direct relationships
to number of income sources. Variables which had significant negative
relationships with hours spent in home production were place of residence
and age. Access to farm technologies had a positive relationship. The
positive predictors of total income were: primary education, secondary
education or above, number of income sources, place of residence, land
holding size and access to farm technologies. Home production time and
health status were negatively related to total income. Total income and hours
spent in home production were significant and positively related to a well-being
score, derived from four measures of well-being. Health status was
negatively related to this score.
Five variables: place of residence, age, primary education, secondary
education or above and access to farm technologies had indirect effects on
total income through number of income sources and home production. All
independent variables entered had indirect effects on the well-being score
through total income and hours spent in home production. Number of income
sources only mediated the effects on the well-being score jointly with total
income. On the whole, both intervening variables did a fair job of mediating
the effects of independent variables on total income and subjective well-being
(well-being score).
Finally, household size, health status and subjective well-being
significantly affected overall satisfaction with life. This study has implications
for policy, education/training and research in order to enhance women's well-being

Do primary care placements influence career choice: What is the evidence?
BACKGROUND: The NHS is struggling with GP recruitment. The Health Education England (HEE) Wass Report (By Choice not by Chance), among its recommendations to boost GP numbers, highlighted undergraduate (UG) GP placement experience as an important influence on future career choice. AIM: To explore the UG influences on GP career choice. METHODS: Two junior doctors produced a pragmatic rapid appraisal of the literature on the UG influences on GP career choice for the Wass Report. The search strategy was supported by librarians and focused on rapidly accessing and summarising relevant literature. Databases searched, including Medline, EMBASE, HMIC & grey literature, revealed 294 items. Data extraction and synthesis was pragmatic. RESULTS: The international evidence suggests that UG GP experience can positively influence students towards a primary care career. Longitudinal placements are more influential than traditional blocks. UK literature is limited, but there are consistencies with the international evidence. The relevant studies identified are observational with risk of bias, but this is unavoidable within this research context. DISCUSSION: The implications of these results for medical school curricula are discussed with particular reference to Government plans to expand medical student numbers and establish new medical schools with explicit aims to produce more GPs
5′′-(4-Chlorobenzylidene)-1′,1′′-dimethyl-3′-phenylacenaphthene-1-spiro-2′-pyrrolidine-3′-spiro-3′′-pyridine-2,4′′-dione
In the title compound, C34H28Cl2N2O2, the five-membered pyrrolidine ring adopts an envelope conformation and the six-membered piperidinone ring is in a distorted half-chair conformation. The molecular structure shows three intramolecular C—H⋯O interactions and the crystal packing is stabilized through intermolecular C—H⋯O and C—H⋯π interactions
Remote monitoring and discrete data capture of joint pain and other parameters via the NokiaN900 device: Enhancing patient/physician interaction
The new generation cellular phones have multi-functional capabilities such as imaging, video, audio recording and messaging in addition to providing internet access. In this paper we present an innovative application in the field of remote health monitoring using N900 Nokia tablet, which will serve as a communicating device between the patient and healthcare providers like doctors and nurses. Patients with arthritis require regular objective monitoring of their affected joints by healthcare providers requiring that patients report their subjective pain levels to their physicians. The application has a patient's module allowing the patient to select their pain level on a sliding scale from a graphical representation of various human joints and send this as an SMS to the doctor. The healthcare providers can review the pain level, save it to a database and make an informed decision about possible recommendations based on the data received via SMS. The doctor's module allows the doctor to capture all the attributes of an affected joint discretely using the graphical representation of the joints and associated dialog boxes. The complete Graphical User Interface (GUI) development and data base design are discussed and test cases are presented. We plan to evaluate the application in a real healthcare environment for usability, its role in improving patient satisfaction and health outcomes
