Constraint-based Query Distribution Framework for an Integrated Global Schema

Distributed heterogeneous data sources need to be queried uniformly using global schema. Query on global schema is reformulated so that it can be executed on local data sources. Constraints in global schema and mappings are used for source selection, query optimization,and querying partitioned and replicated data sources. The provided system is all XML-based which poses query in XML form, transforms, and integrates local results in an XML document. Contributions include the use of constraints in our existing global schema which help in source selection and query optimization, and a global query distribution framework for querying distributed heterogeneous data sources.Comment: The Proceedings of the 13th INMIC 2009), Dec. 14-15, 2009, Islamabad, Pakistan.

Impact of Project and Programme Aid on Economic Growth: A Cross Country Analysis

This study examines the impact of foreign aid instruments, namely Project Aid and Programme Aid, on economic growth of 27 aid-receiving countries. The study constructs a system of three equations, i.e. growth, investment and human capital. Using the Generalised Method of Moment estimation technique, the study concludes that while Project Aid has a positive and significant impact on economic growth, Programme Aid has an insignificant impact on economic growth. Additionally, the study finds that economic policies do enhance effectiveness of aid at aggregate level. Therefore, the capacity of aid-recipient countries to effectively use their resources for economic development needs due consideration.

How has Outsourcing Human Resource (HR) Services within National Health Services (NHS) Impacted upon Staff Turnover and Wider Local Economy in UK?

This paper critically investigates how outsourcing human resource (HR) services within National Health Services (NHS) have affected staff turnover and wider local economy of UK. Interviews were structured with the view to investigate this issue. The research shows that despite the pressure of outsourcing by Department of Health (DoH), NHS acute trusts are reluctant to outsource their HR functions. Those who outsourced have done this with some strategic planning. Reverse trend of outsourcing has also been observed. Outsourcing HR functions have not lost as many jobs as it was expected. No direct relationship was observed in the wider local economy and outsourcing in NHS trusts. According to findings of the research HR outsourcing has not drastic effects on wider local economy if observed on small scale

MaintainoMATE: A GitHub App for Intelligent Automation of Maintenance Activities

Software development projects rely on issue tracking systems at the core of tracking maintenance tasks such as bug reports, and enhancement requests. Incoming issue-reports on these issue tracking systems must be managed in an effective manner. First, they must be labelled and then assigned to a particular developer with relevant expertise. This handling of issue-reports is critical and requires thorough scanning of the text entered in an issue-report making it a labor-intensive task. In this paper, we present a unified framework called MaintainoMATE, which is capable of automatically categorizing the issue-reports in their respective category and further assigning the issue-reports to a developer with relevant expertise. We use the Bidirectional Encoder Representations from Transformers (BERT), as an underlying model for MaintainoMATE to learn the contextual information for automatic issue-report labeling and assignment tasks. We deploy the framework used in this work as a GitHub application. We empirically evaluate our approach on GitHub issue-reports to show its capability of assigning labels to the issue-reports. We were able to achieve an F1-score close to 80\%, which is comparable to existing state-of-the-art results. Similarly, our initial evaluations show that we can assign relevant developers to the issue-reports with an F1 score of 54\%, which is a significant improvement over existing approaches. Our initial findings suggest that MaintainoMATE has the potential of improving software quality and reducing maintenance costs by accurately automating activities involved in the maintenance processes. Our future work would be directed towards improving the issue-assignment module

Challenges Faced by the Repatriates and their Subsequent Impact on Repatriates’ Satisfaction

Objective: Through decades repatriation has been the most ignored and a problematic phase of the Expatriate Management Cycle (EMC). Expatriates when returning back to their home country are referred as Repatriates and this returning phase is known as Repatriation phase of the Expatriate Management Cycle. This Repatriation phase is mainly the unplanned stage where organizational managers make the mistake. They certainly believe that the repatriates are returning back to their home and wrongly assumes that there will be no complications or challenges for these repatriates on their arrival back to home country. This strategic lack results in the immense dissatisfaction of these repatriates soon after arrival to the home county. Our aim is to provide a detailed study on the process of repatriation by identifying the challenges that are faced by the repatriates on their arrival to the home country and to oversee their subsequent impact on their job performance. Methodology: Data was collected through primary means using convenience sampling method through various organizations and of 300 respondents 186 were filtered out to be analyzed using different statistical techniques on SPSS. Result: There exist a significant negative relationship between all the identified challenges faced by the repatriates and their job satisfaction level Implication: At the end of the research some recommendations were also proposed for the organizational managers to overcome these challenges. This piece of research can not only be used by the researchers for their research work but can also be based by the organizational managers to formulate their repatriation strategies

DSLOT-NN: Digit-Serial Left-to-Right Neural Network Accelerator

We propose a Digit-Serial Left-tO-righT (DSLOT) arithmetic based processing technique called DSLOT-NN with aim to accelerate inference of the convolution operation in the deep neural networks (DNNs). The proposed work has the ability to assess and terminate the ineffective convolutions which results in massive power and energy savings. The processing engine is comprised of low-latency most-significant-digit-first (MSDF) (also called online) multipliers and adders that processes data from left-to-right, allowing the execution of subsequent operations in digit-pipelined manner. Use of online operators eliminates the need for the development of complex mechanism of identifying the negative activation, as the output with highest weight value is generated first, and the sign of the result can be identified as soon as first non-zero digit is generated. The precision of the online operators can be tuned at run-time, making them extremely useful in situations where accuracy can be compromised for power and energy savings. The proposed design has been implemented on Xilinx Virtex-7 FPGA and is compared with state-of-the-art Stripes on various performance metrics. The results show the proposed design presents power savings, has shorter cycle time, and approximately 50% higher OPS per watt.Comment: Presented at 2023 26th Euromicro Conference on Digital System Design (DSD

Evaluation of Prognostic response in HIV positive patients after Antiretroviral Therapy

Objective: The present study was aimed to monitor the prognostic response of antiretroviral therapy in HIV positive patients. Methodology: The study was conducted on confirmed HIV positive patients registered at HIV treatment and care centre, PIMS. Islamabad from January 2013 to December 2015.. Among all HIV positive patients,276 adult cases were selected. There were 263 patients on first-line antiretroviral (ARV) therapy and 13 patients were shifted to 2nd line ARV therapy.CD4 cell counts and viral load (Polymerase chain reaction) monitoring was done after one year of starting ARV therapy. Results: Out of 276 adult patients,  75%(n=207) were male and 25%(n=69) were females. Among 276 adult cases, 95.3% (n=263) patients were on first line ARV therapy. Patients on first line ARV therapy showed good prognostic response. There  were 15.5%(n=40) patients having  CD4+cells less than 350cells/µL. There were 84.5%(n=223) patients having  CD4 +cells count greater than 350cells/µL There were 69%(n=182) patients having viral load <50copies/ml and 31%(n=81) patients who had viral load >50copies/ml. Conclusion: First line ARV therapy given to HIV positive patients proved itself best both in respect of increasing the immunity of HIV positive patients by increasing the number of CD4 cells and also results in effective viral load suppression
