Organisational commitment of various groups of professionals seems to be moderated by the differences of the groups as well as of the socialisation experiences Demographic variable ‘age’ and the semi-structural variable ‘experience’ cause a difference in the level of commitment. Similarly, the professional and organisational differences moderate the level of commitment. From the point of view of the organisations, the socialisation experiences if differ can be used as tool to process and enhance the level of commitment of professionals of various groups.The ‘Socialisation effect’ does not depend on the professional or demographic differences. Socialisation level is moderated only by the organisational specialities. It is purely an organisational variable. However, the difference in the socialisation levels as found among the professionals can cause a significant difference in the levels of organisational commitment of professionals

In this study of workers of the two industrial units, it has been found that the women workers are more committed to the organization than the men workers. The organizational commitment has been a popular research topic among organizational sociologists, industrial psychologists and labour relations specialists. Much of the early research was directed on organizational commitment of men workers and studies on organizational commitment of women workers were less when compared to that of men workers. The results of this study is partially supported by the findings of Aranya and Jacobson (1975) who found that parental responsibility is linked with maintaining stable patterns of employment.

This paper describes JERIM-320, a new 320-bit hash function used for ensuring message integrity and details a comparison with popular hash functions of similar design. JERIM-320 and FORK -256 operate on four parallel lines of message processing while RIPEMD-320 operates on two parallel lines. Popular hash functions like MD5 and SHA-1 use serial successive iteration for designing compression functions and hence are less secure. The parallel branches help JERIM-320 to achieve higher level of security using multiple iterations and processing on the message blocks. The focus of this work is to prove the ability of JERIM 320 in ensuring the integrity of messages to a higher degree to suit the fast growing internet applications

Unit Commitment Problem (UCP) in power system refers to the problem of determining the on/ off status of generating units that minimize the operating cost during a given time horizon. Since various system and generation constraints are to be satisfied while finding the optimum schedule, UCP turns to be a constrained optimization problem in power system scheduling. Numerical solutions developed are limited for small systems and heuristic methodologies find difficulty in handling stochastic cost functions associated with practical systems. This paper models Unit Commitment as a multi stage decision making task and an efficient Reinforcement Learning solution is formulated considering minimum up time /down time constraints. The correctness and efficiency of the developed solutions are verified for standard test systems

Unit commitment is an optimization task in electric power generation control sector. It involves scheduling the ON/OFF status of the generating units to meet the load demand with minimum generation cost satisfying the different constraints existing in the system. Numerical solutions developed are limited for small systems and heuristic methodologies find difficulty in handling stochastic cost functions associated with practical systems. This paper models Unit Commitment as a multi stage decision task and Reinforcement Learning solution is formulated through one efficient exploration strategy: Pursuit method. The correctness and efficiency of the developed solutions are verified for standard test systems

Seit über zehn Jahren wird in der rechtswissenschaftlichen Literatur der Beweiswert elektronischer Signaturen diskutiert. Alle bisherigen Abhandlungen sind jedoch rein theoretischer Natur. Auch beschäftigen sie sich nur mit einem Teil der Problematik, indem sie lediglich einen relativ kurzen Zeitpunkt nach der Signaturerzeugung betrachten. Praktische Erfahrungen mit der Beweisführung mittels elektronisch signierter Dokumente fehlen vollständig. Im Forschungsprojekt "ArchiSig" konnten nun erstmals praktische Erfahrungen gewonnen werden, die zur Schließung beider Lücken beitragen können. Der vorliegende Aufsatz stellt die aus einer Simulationsstudie gewonnenen Erkenntnisse tatsächlicher Beweiserhebungen mit elektronisch signierten Dokumenten dar und zeigt Konsequenzen für die sichere Langzeitaufbewahrung auf.

This paper reports on results from five companies in the aerospace and automotive industries to show that over-commitment of technical professionals and under-representation of key skills on technology development and transition teams seriously impairs team performance. The research finds that 40 percent of the projects studied were inadequately staffed, resulting in weaker team communications and alignment. Most importantly, the weak staffing on these teams is found to be associated with a doubling of project failure rate to reach full production. Those weakly staffed teams that did successfully insert technology into production systems were also much more likely than other teams to have development delays and late engineering changes. The conclusion suggests that the expense of project failure, delay and late engineering changes in these companies must greatly out-weigh the savings gained from reduced staffing costs, and that this problem is likely going to be found in other technology-intensive firms intent on seeing project budgets as a cost to be minimized rather than an investment to be maximized.

It has been widely known that a significant part of the bits are useless or even unused during the program execution. Bit-width analysis targets at finding the minimum bits needed for each variable in the program, which ensures the execution correctness and resources saving. In this paper, we proposed a static analysis method for bit-widths in general applications, which approximates conservatively at compile time and is independent of runtime conditions. While most related work focus on integer applications, our method is also tailored and applicable to floating point variables, which could be extended to transform floating point number into fixed point numbers together with precision analysis. We used more precise representations for data value ranges of both scalar and array variables. Element level analysis is carried out for arrays. We also suggested an alternative for the standard fixed-point iterations in bi-directional range analysis. These techniques are implemented on the Trimaran compiler structure and tested on a set of benchmarks to show the results.

In this paper, we develop a novel index structure to support efficient approximate k-nearest neighbor (KNN) query in high-dimensional databases. In high-dimensional spaces, the computational cost of the distance (e.g., Euclidean distance) between two points contributes a dominant portion of the overall query response time for memory processing. To reduce the distance computation, we first propose a structure (BID) using BIt-Difference to answer approximate KNN query. The BID employs one bit to represent each feature vector of point and the number of bit-difference is used to prune the further points. To facilitate real dataset which is typically skewed, we enhance the BID mechanism with clustering, cluster adapted bitcoder and dimensional weight, named the BID⁺. Extensive experiments are conducted to show that our proposed method yields significant performance advantages over the existing index structures on both real life and synthetic high-dimensional datasets.

La inversión extranjera constituye una oportunidad de elevar los índices de crecimiento y desarrollo económico de Colombia. Desde la reforma económica de 1990-1994, el país cambió su política frente a temas como: la economía, las finanzas públicas, la estructura empresarial, el sector agrícola y la base tributaria, entre otros. En respuesta a este cambio, con la entrada de las políticas de corte neoliberal y el nuevo sistema político e institucional del país, se modificaron sus estructuras e instituciones. Asimismo surgieron nuevas prioridades. De ahí que se iniciaran también nuevas relaciones estratégicas‚ con otros Estados, para satisfacer estos nuevos intereses. Dentro de estas nuevas prioridades surgió el interés de atraer inversión extranjera directa y de portafolio. En ese momento‚ e inclusive ahora se hace necesario financiar la economía emergente y nada más propicio que la inversión extranjera para este propósito. Es decir, se complementa el crecimiento económico, con flujos de capital externo, que puede llegar en forma de inversión directa o de figuras financieras como las acciones, los bonos, etc.

A clinical case of compulsive gambling is exposed in this article. The subject’s playing behaviour had both positive and negative consequences. The subject tried to practice control over the urge to play. As shown in the functional analysis, the failure to control the urge despite the best efforts worsened the problem due to its negative consequences. A variation of acceptance and commitment therapy (ACT) was applied in order to break down the fight-surrender vicious circle of the playing behaviour. Two treatment strategies were agreed upon: acceptance of the fact that both playing and not playing had negatives consequences and commitment to one of these options despite its disadvantages. Finally, it is proposed that this acceptance and commitment therapy is a useful therapeutic process as it decreases the suffering subject and eliminates the problem: playing bahaviour.
