The regulations concerning preliminary profit announcements are contained in the Listing Rules of the Stock Exchange. The disclosure provisions are modest and there is no requirement for the document to be audited. There have been criticisms concerning the ambiguity of the auditors’ involvement and the timing of the release of information for a number of years. Amendments introduced in 1993 have done little to resolve the matter. As an empirical study of 148 randomly selected listed companies, seeks answers to the following three questions: Does the audit status have any relationship with the size or type of company? Is the audit status associated with the timing of the release of information? Is the audit status associated with the voluntary provision of additional financial statements? Concludes that there is considerable variety in company practice and that the Stock Exchange should take action to dispel the ambiguities concerning auditors’ involvement with preliminary profit announcements.

This paper aims to study the Integrated Criminal Justice System; the law enforcement carried out by the Indonesian National Police is expected to be able to realize legal values, namely, legal justice, expediency and certainty.

This research can broadly be grouped into the realm of the socio-legal research approach. The domain of law enforcement in corruption cases is related to the preliminary investigation and full investigation process. The research location chosen is at Indonesian National Police Headquarter (Mabes Polri) and Greater Jakarta Metropolitan Regional Police. The main data sources are stakeholders who are related and have the authority as preliminary phase investigators and full phase investigators. The next informants are determined by snowball technique, which consists of several informants as follows: Director of Special Criminal Investigation Directorate of Greater Jakarta Metropolitan Regional Police, head of Corruption Crime Sub-Directorate of Greater Jakarta Metropolitan Regional Police, investigators of Corruption Crime Sub-Directorate of Special Criminal Investigation Directorate of Greater Jakarta Metropolitan Regional Police, members of Commission III of the Indonesian House of Representatives (DPR), constitutional law experts and police experts. The data in this research are obtained through observation activities, visual interviews, document interpretation (text) and material and personal experience.

The corruption cases handled by the Indonesian National Police have mostly come from information reports from the public. Based on the information report from the community, the preliminary investigation phase is carried out by the preliminary phase investigator of the Indonesian National Police in the field. In addition, a preliminary investigation and full investigation is carried out due to the results of an audit from the BPK or BPKP. Preliminary investigation and full investigation begin after it is alleged that a criminal act of corruption had occurred based on the report, complaints and information received by the preliminary phase investigator or full phase investigator from the community. In conducting the preliminary investigation and full investigation of corruption cases, based on the results of the research conducted, it is also found that the Indonesian National Police’s preliminary phase investigator and full phase investigator experience several obstacles, besides supporting factors that support the success of a preliminary investigation and full investigation.

This research is a case study in which no previous studies have used the same method in Greater Jakarta Metropolitan Regional Police (Polda Metro Jaya). This paper is the result of the researcher’s research on what is described above, guided by the constructivism paradigm, the researcher applies the paradigmatic analysis to understand how the preliminary investigation and full investigation on corruption crimes by Greater Jakarta Metropolitan Regional Police act as part of an integrated criminal justice system. Through the paradigmatic analysis, the researcher then reveals how while upholding the law, the Indonesian National Police actually sought to realize legal justice, expediency and certainty.

Preparation of preliminary estimate is difficult owing to the lack of full project details in the early phases of the construction project. This paper seeks to assess the estimation techniques used for road projects and the critical factors affecting their accuracy in the Ghanaian construction industry.

Quantitative research design was adopted and questionnaire was designed to retrieve data. The target population were engineers and quantity surveyors who were contacted using an e-questionnaire through their professional bodies owing to location constraints. Retrieved data were analysed using descriptive and exploratory factor analysis. In order to compare the opinions of the respondents, the Mann–Whitney U-test was employed.

The survey revealed that subjective, parametric, comparative and analytical estimations are in use in Ghana. The most critical factors influencing the accuracy of estimation techniques are improper project planning, insufficient preliminary site investigation and usage of shortcuts, among others.

This study was limited to Accra, Ghana, due to time and distance constraint.

For accuracy of preliminary estimates to be improved, estimators being the custodian of the estimate are expected to be devoid of errors such as arithmetic calculation errors, inaccurate quantity measurement and error of omission. The usage of estimating software can eliminate these human errors.

The study will assist policymakers and stakeholders in aligning mitigative actions for factors influencing preliminary estimate of road projects with defined clusters rather than basic ranks. With attention focussed on the characteristics of each cluster, accuracy of preliminary estimate can be improved.

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

This paper aims assess to the perceived importance (PI) and actual implementation (AI) of five preliminary knowledge management (KM) success factors, i.e. business strategy, organizational structure, knowledge team, knowledge audit, and knowledge map in the Malaysian telecommunication industry.

A questionnaire survey was conducted on telecommunication organizations located in the capital of Malaysia. Data were analyzed using indices and parametric statistics.

The results show that the organizations are aware of the importance of all the KM factors but fall short of implementation. The implemented factors consist of business strategy, organizational structure, and knowledge team. Knowledge audit and knowledge map are perceived as important but are the least implemented factors.

This study was conducted in only one industry in Malaysia. Furthermore, it focuses on the preliminary success factors of KM implementation rather than on learning and knowledge utilization.

Telecommunication organizations have to overcome resources problems and enhance implementation level in order to narrow the gaps for effective, full scale KM implementation in the later stage. Such viable practice will significantly help the industry not only to compete more effectively within Malaysia, but also to position itself as a global player in the world.

This study is perhaps one of the first to address the preliminary steps to be dealt with prior to KM implementation. Moreover, it attempts to compare the PI and AI of the five proposed success factors, which has received very little attention to date.

The purpose of this paper is to compare twin engine civil turboprop aircraft with their jet engine counterparts; to simplify the preliminary design process and the initial evaluation of twin civil turboprop aircraft; to include noise level consideration in the preliminary design; and to form a current database of design parameters for representative civil turboprop aircraft.

The paper finds linear correlations between key design parameters. It compares the corresponding correlations for turboprop and jet engine aircraft.

The paper finds direct linear relationships between design parameters including noise levels; simplified preliminary design process; and differences in the sensitivity of design parameters between turboprop and jet aircraft.

The turboprop aircraft database needs to be expanded. Also, investigation of non‐linear relations between design parameters is a next step.

Quick assessment and comparisons of existing designs is an outcome. Also, the preliminary design process is simplified and expedited. Lastly, noise regulations can affect the design right from the beginning and not at a later stage.

New correlations which simplify the current procedures for preliminary design of twin civil turboprop aircraft. In addition, the noise is included right from the beginning of the design. Direct comparison between turboprop and jet aircraft afforded via their correlated preliminary design parameters. Finally, a database of twin turboprops is formed with specially selected aircraft that are current and cover a wide spectrum of sizes.

This paper aims to set up and assess a new method to collaboratively mature the requirements for engine development in a more efficient way during the preliminary design phase.

A collaborative process has been set up in which detailed information on the behaviour of designed engines has been integrated into the aircraft preliminary sizing process by means of surrogate modelling.

The engine surrogate model has been invoked as a black box from within the aircraft preliminary design optimisation loops. The surrogate model reduces the uncertainty of coarse-grain formulas and may result in more competitive aircraft and engine designs. The surrogate model has been integrated in a collaborative cross-organisational workflow between aircraft manufacturer, engine manufacturer and simulation service providers to prepare for its deployment in industrial preliminary design processes.

The new collaborative way of working between aircraft manufacturer, engine manufacturer and simulation service providers could contribute to remove time consuming rework cycles in early and later design stages within delivering the optimal aircraft-engine combination.

The assessed process, based on an innovative collaboration standard, provides the opportunity to introduce useful design iterations with much more enriched information than in the classical design process as performed today. Specifically, the application of an engine surrogate model is advantageous, as it allows for extensive trade-off studies on aircraft level because of the low computational effort, while the intellectual property of the engine manufacturer (the engine preliminary design process) is respected and kept in-house.

The purpose of this paper is to assess the perceived importance and actual level of implementation of five preliminary success factors, four knowledge management (KM) strategies and three KM processes towards the performance of the Malaysian telecommunication industry.

A questionnaire survey was conducted on telecommunication companies based on a convenience sampling technique. Data were analyzed using paired t‐tests and multiple regression analyses.

The results show that Malaysian telecommunication organizations view all the KM preliminary success factors, strategies and process as important and critical but fall short of implementation. K Audit, K Map, leadership, measurement, construction and embodiment are the variables that have the largest gap between perceived importance and actual implementation. For perceived importance, culture is the only important variable associated with organizational performance whereas for actual implementation, both business strategy and construction process are found to be significantly associated with organizational performance.

This paper was conducted in only one industry in Malaysia. Furthermore, it focuses on KM implementation rather than on learning and knowledge utilization. This paper provides a framework for developing an instrument for assessing the use of preliminary elements in the Malaysian telecommunication industry. Telecommunication organizations have to overcome problems identified and enhance their implementation level in order to achieve better organizational performance.

This paper has extended knowledge in KM, especially concerning implementation issues at the beginning stage of KM. Moreover, it is among the first empirical work to specifically examine preliminary success factors, processes and strategies that affect the preliminary implementation of KM.
