How to Use a Desktop Version of a DBMS for Client-Server Applications

DBMS (Data base management systems) still have a very high price for small and middle enterprises in Bulgaria. Desktop versions are free but they cannot function in multi-user environment. We will try to make an application server which will make a Desktop version of a DBMS open to many users. Thus, this approach will be appropriate for client-server applications. The author of the article gives a concise observation of the problem and a possible way of solution.

Client discourses on the process of seeking same-sex couple counselling

How same-sex couples manage the process of seeking help for their relationships is an under-researched area. Twelve semi-structured interviews were conducted with 16 people who had engaged in same-sex couple counselling, and were analysed using discourse analysis. The ways in which the couples positioned themselves as part of a 'minority group', or part of a generic group of couples struggling with relationship issues, impacted on how they discussed seeking help. We conclude that counsellors and psychotherapists need to be aware of the ways in which couples construct their relationships, and mindful of the tricky navigations around similarity to, and difference from, different-sex relationships. The impact of this on couples seeking therapeutic help is considered. © 2013 Taylor & Francis.

Client QoE-oriented segment selection for DASH

A segment selection method controlled by Quality of Experience (QoE) factors for Dynamic Adaptive Streaming over HTTP (DASH) is presented in this paper. Current rate adaption algorithms aim to eliminate buffer underrun events by significantly reducing the code rate when experiencing pauses in replay. In reality, however, viewers may choose to accept a level of buffer underrun in order to achieve an improved level of picture fidelity or to accept the degradation in picture fidelity in order to maintain the service continuity. The proposed rate adaption scheme in our work can maximize the user QoE in terms of both continuity and fidelity (picture quality) in DASH applications. It is shown that using this scheme a high level of quality for streaming services, especially at low packet loss rates, can be achieved. Our scheme can also maintain a best trade-off between continuity-based quality and fidelity-based quality, by determining proper threshold values for the level of quality intended by clients with different quality requirements. In addition, the integration of the rate adaptation mechanism with the scheduling process is investigated in the context of a mobile communication network and related performances are analyzed.

Coping with a diagnosis of Alzheimer's disease: A client and caregiver perspective

The purpose of this study was to examine how individuals and their caregivers cope with a diagnosis of Alzheimer's disease. The sample size consisted of six patients with Alzheimer's disease and seven caregivers. The caregivers included spouses and adult children. The study was conducted at an academic medical center in the South Florida area. Using a phenomenological approach, data were collected by audiotaped interviews. Data were analyzed following the seven steps of Colaizzi (1978).^ The results of the study indicated that clients experienced fear, social withdrawal, decreased self-esteem and a need for love and support. Caregivers experienced psychological strain, burden, lifestyle adjustments and sacrifice. Both clients and caregivers identified numerous strategies for coping with Alzheimer's disease. The findings reflect the need for a holistic approach to promoting the quality of life for patients and caregivers. ^

Algorithms for efficient transaction management and consistent queries in client -server semantic object-oriented parallel databases

Large read-only or read-write transactions with a large read set and a small write set constitute an important class of transactions used in such applications as data mining, data warehousing, statistical applications, and report generators. Such transactions are best supported with optimistic concurrency, because locking of large amounts of data for extended periods of time is not an acceptable solution. The abort rate in regular optimistic concurrency algorithms increases exponentially with the size of the transaction. The algorithm proposed in this dissertation solves this problem by using a new transaction scheduling technique that allows a large transaction to commit safely with significantly greater probability that can exceed several orders of magnitude versus regular optimistic concurrency algorithms. A performance simulation study and a formal proof of serializability and external consistency of the proposed algorithm are also presented.^ This dissertation also proposes a new query optimization technique (lazy queries). Lazy Queries is an adaptive query execution scheme which optimizes itself as the query runs. Lazy queries can be used to find an intersection of sub-queries in a very efficient way, which does not require full execution of large sub-queries nor does it require any statistical knowledge about the data.^ An efficient optimistic concurrency control algorithm used in a massively parallel B-tree with variable-length keys is introduced. B-trees with variable-length keys can be effectively used in a variety of database types. In particular, we show how such a B-tree was used in our implementation of a semantic object-oriented DBMS. The concurrency control algorithm uses semantically safe optimistic virtual "locks" that achieve very fine granularity in conflict detection. This algorithm ensures serializability and external consistency by using logical clocks and backward validation of transactional queries. A formal proof of correctness of the proposed algorithm is also presented. ^

Predictors of client retention in alternative -to -prison substance abuse programs

Increased treatment retention among substance abusing individuals has been associated with reduced drug use, fewer arrests, and decreased unemployment, as well as a reduction in health risk behaviors. This longitudinal study examined the predictors of client retention for alternative to prison substance abuse treatment programs through assessing the roles of motivational factors and the client-worker relationship. The sample was comprised of 141 male felony offenders who were legally mandated to community based long-term residential drug treatment programs. ^ The primary measures used in the study were the consecutive days a participant remained in treatment, Stages of Change Readiness Model and Treatment Eagerness Scale (SOCRATES), the Working Alliance Inventory (WAI), and The Readiness Ruler. Hierarchical multiple regression analysis was conducted for four hypotheses (a) participants who are more motivated to change at the time of entry will remain in treatment longer, (b) participants who have a strong therapeutic alliance will remain in treatment a greater number of consecutive days than participants who have weaker therapeutic alliance, (c) motivation to change, as measured at treatment entry, will be positively related to therapeutic alliance, (d) during the course of treatment variation in motivation to change will be predicted by the therapeutic alliance. ^ Results support the following conclusions: Among clients in alternative-to prison programs the number of days in treatment is positively related to their motivation to change. The therapeutic alliance is not a predictor of the number of days in treatment. Motivation to change, particularly recognition of a drug problem, is positively related to the therapeutic alliance. Changes in motivation to change in response to treatment are positively related to the therapeutic alliance among clients in an alternative to prison substance abuse treatment programs. These results carry forward prior research and have implications for social work practice, research, and social welfare policy. ^

Development of a new client -server architecture for context aware mobile computing

This dissertation studies the context-aware application with its proposed algorithms at client side. The required context-aware infrastructure is discussed in depth to illustrate that such an infrastructure collects the mobile user’s context information, registers service providers, derives mobile user’s current context, distributes user context among context-aware applications, and provides tailored services. The approach proposed tries to strike a balance between the context server and mobile devices. The context acquisition is centralized at the server to ensure the reusability of context information among mobile devices, while context reasoning remains at the application level. Hence, a centralized context acquisition and distributed context reasoning are viewed as a better solution overall. The context-aware search application is designed and implemented at the server side. A new algorithm is proposed to take into consideration the user context profiles. By promoting feedback on the dynamics of the system, any prior user selection is now saved for further analysis such that it may contribute to help the results of a subsequent search. On the basis of these developments at the server side, various solutions are consequently provided at the client side. A proxy software-based component is set up for the purpose of data collection. This research endorses the belief that the proxy at the client side should contain the context reasoning component. Implementation of such a component provides credence to this belief in that the context applications are able to derive the user context profiles. Furthermore, a context cache scheme is implemented to manage the cache on the client device in order to minimize processing requirements and other resources (bandwidth, CPU cycle, power). Java and MySQL platforms are used to implement the proposed architecture and to test scenarios derived from user’s daily activities. To meet the practical demands required of a testing environment without the impositions of a heavy cost for establishing such a comprehensive infrastructure, a software simulation using a free Yahoo search API is provided as a means to evaluate the effectiveness of the design approach in a most realistic way. The integration of Yahoo search engine into the context-aware architecture design proves how context aware application can meet user demands for tailored services and products in and around the user’s environment. The test results show that the overall design is highly effective, providing new features and enriching the mobile user’s experience through a broad scope of potential applications.

Lien entre l'efficacité de la consultation organisationnelle et la relation client-consultant selon la perspective du client

Depuis quelques décennies, la consultation en contexte organisationnel constitue une pratique professionnelle importante. L’efficacité de la consultation est l’un des enjeux de la pratique tant pour les clients que pour les consultants. Certains auteurs ont développé des modèles pour comprendre le processus de consultation et ses composantes. La documentation sur l’efficacité de la consultation fait ressortir la contribution de la relation client-consultant comme facteur explicatif. Toutefois, peu d’études se sont penchées sur le lien statistique entre la relation client-consultant et l’efficacité de la consultation comme pratique globale. Cette recherche s’intéresse à la relation client-consultant telle qu’exprimée par ses activités (variable indépendante) et à leurs portées sur l’efficacité de la consultation organisationnelle (variable dépendante) telle qu’évaluée par des clients. Les bases théoriques et empiriques en contextes clinique et organisationnel portent à croire qu’il existe une relation positive significative entre ces deux variables. Ainsi, pour cette étude, une hypothèse est posée : les activités de la relation client-consultant sont en relation de façon positive avec l’efficacité de la consultation telle qu’évaluée par le client. Cette étude a été menée auprès de 88 clients. Les données utilisées pour cette étude ont été recueillies en un seul temps de mesure avec deux instruments combinés dans le questionnaire CERCC-CL édité sur Internet, via Survey Monkey, et crypté pour assurer la sécurité et la confidentialité des données. Les résultats révèlent que la relation se décline en quatre dimensions : 1) entente professionnelle; 2) réciprocité; 3) soutien du consultant et 4) compatibilité personnelle. L’hypothèse est en grande partie corroborée; trois dimensions de la relation, soit (1) entente professionnelle, (2) réciprocité et (4) compatibilité personnelle, influencent la qualité d’une démarche de consultation, l’un des deux critères de l’efficacité et l’efficacité de la consultation dans sa globalité. La compatibilité personnelle (4) influence les résultats à valeur ajoutée, le second critère de l’efficacité. Le score global de la relation client-consultant permet de prédire de façon significative les deux facteurs d’efficacité de la consultation et l’efficacité globale. L’ensemble de ces résultats apporte un premier éclairage sur la contribution potentielle de deux nouveaux questionnaires permettant au client et au consultant de s’évaluer en cours de processus ou à la fin de celui-ci. Les résultats contribuent surtout à la considération et à une meilleure compréhension de l’importance de la relation client-consultant pour expliquer l’efficacité d’une intervention. La relation client-consultant selon la perspective du client, principal acteur à satisfaire, favorise une vision positive du mandat. Pour le consultant, cette étude fait valoir l’importance de miser et de parfaire ses habiletés relationnelles indépendamment de son domaine d’expertise s’il veut être efficace dans sa pratique de la consultation.
