As the field of action-oriented research becomes increasingly diffuse and diverse, this paper seeks to identify common ground across the multiple modalities of action research and collaborative management research through articulating and exploring a general empirical method that is grounded in the recognizable structure of human knowing. This method is grounded in: attention to observable data (experience), envisaging possible explanations of that data (understanding), and preferring as probable or certain the explanations, which provide the best account for the data (judgment). Engaging this method requires the dispositions to perform the operations of attentiveness, intelligence, and reasonableness, to which responsibility is added when we seek to take action. This paper seeks to provide insight into the multiple modalities of action research and collaborative management research and to illustrate how each modality engages the recognizable operations of human knowing.

Within the developing exploration of the role of the scholar-practitioner, the situation in which scholar-practitioners engage in the scholarship of practice in their own organizational systems has not received much attention. This chapter adopts the position that scholar-practitioners are not merely practitioners who do research but rather that they integrate scholarship in their practice and generate actionable knowledge, that is, knowledge that is robust for scholars and actionable for practitioners. This chapter explores the phenomenon of scholar-practitioners engaging in the scholarship of practice in their own organizational systems as inside change agents. It discusses how scholar-practitioners engage in inquiry-in-action in first-, second-, and third-person modes of inquiry and practice in the present tense and provides a methodology and methods for such engagement that it be rigorous, reflective, and relevant.

Capacitors are one of the most common passive components on a circuit board. From a tiny toy to substantial satellite, a capacitor plays an important role. Untimely failure of a capacitor can destruct the entire system. This research paper targets the reliability assessment of tantalum capacitor, to reduce e-waste and enhance its reusable capability.

The residual lifetime of a tantalum capacitor is estimated using the empirical method, i.e. military handbook MILHDBK2017F, and validated using an experimental approach, i.e. accelerated life testing (ALT). The various influencing acceleration factors are explored, and experiments are designed using Taguchi's approach. Empirical methods such as the military handbook is used for assessing the reliability of a tantalum capacitor, for ground and mobile applications.

After exploring the lifetime of a tantalum capacitor using empirical and experimental techniques, an error analysis is conducted, which shows the validity of empirical technique, with an accuracy of 95.21%.

The condition monitoring and health prognostics of tantalum capacitors, for ground and mobile applications, are explored using empirical and experimental techniques, which warns the user about its residual lifetime so that the faulty component can be replaced in time.

The purpose of this study is to select the most accurate and the most efficient method in estimating Weibull parameters at Agadir region in Morocco.

In this paper, Weibull distribution is used to model the wind speed in hourly time series format. Since several methods are used to adjust the Weibull distribution to the measured data, in reporting and analyzing the easiest and the most effective method, seven methods have been investigated, namely, the graphical method (GM), the maximum likelihood method (MLM), the empirical method of Justus (EMJ), the empirical method of Lysen (EML), the energy pattern factor method (EPFM), Mabchour’s method (MMab) and the method of moments (MM).

According to the statistical analysis tools (the coefficient of determination, root mean square error and chi-square test), it was found that for five months, the MLM presents more efficiency, and for four months, EMJ is ranked first and it is ranked second for February. To select only one method, the selected methods (MLM and EMJ) were compared by calculating the error in estimating the power density using Weibull distribution adjusted by those methods. The average error was found to be −0.51 and −4.56 per cent for MLM and EMJ, respectively.

This investigation is the first of its kind for the studied region. To estimate the available wind power at Agadir in Morocco, investors can directly use MLM to determine the Weibull parameters at this site.

The purpose of this study is to conduct a meta-analysis of prior scientometric research of the knowledge management (KM) field.

A total of 108 scientometric studies of the KM discipline were subjected to meta-analysis techniques.

The overall volume of scientometric KM works has been growing, reaching up to ten publications per year by 2012, but their key findings are somewhat inconsistent. Most scientometric KM research is published in non-KM-centric journals. The KM discipline has deep historical roots. It suffers from a high degree of over-differentiation and is represented by dissimilar research streams. The top six most productive countries for KM research are the USA, the UK, Canada, Germany, Australia, and Spain. KM exhibits attributes of a healthy academic domain with no apparent anomalies and is progressing towards academic maturity.

Scientometric KM researchers should use advanced empirical methods, become aware of prior scientometric research, rely on multiple databases, develop a KM keyword classification scheme, publish their research in KM-centric outlets, focus on rigorous research of the forums for KM publications, improve their cooperation, conduct a comprehensive study of individual and institutional productivity, and investigate interdisciplinary collaboration. KM-centric journals should encourage authors to employ under-represented empirical methods and conduct meta-analysis studies and should discourage conceptual publications, especially the development of new frameworks. To improve the impact of KM research on the state of practice, knowledge dissemination channels should be developed.

This is the first documented attempt to conduct a meta-analysis of scientometric research of the KM discipline.

This research is very important to conduct to review government policy on Indonesian contract law that still uses contract law inherited from Dutch product (BW) and review which regulations are to be adapted to current development of contract law. This research’s novelty is that new rules will be found in Indonesian contract law.

This research used normative and empirical methods. Normative research is dogmatic research or one that analyzes legislation using secondary data consisting of primary, secondary and tertiary legal materials. Besides the normative method, the research was also conducted using empirical method through direct interview and observation in some government agencies, such as the Directorate General of Legislation, Ministry of Law and Human Rights (HAM) and Chairman of Legal Product Formation Division, House of People’s Representatives of the Republic of Indonesia and the Civil Law Teaching Association (APHK).

This research found that new Indonesian contract law is very important to give legal certainty and justice to the people, and the contract law must regulate important matters related to the sources of contract besides agreement and law, related to termination, unjust enrichment, negotiation, good faith, public contract and private contract and related to legal act and validity of electronic contract.

The novelty of this research is that new rules will be found in Indonesian contract law. This research is different from previous researches conducted by Sigit Irianto (2013) and Deviana Yuanitasari (2020), that discuss only on contract law development related only to the good faith principle.

Drafting contract law is a relatively heavy duty due to the factor of law pluralism that contains contract aspect in Indonesia such as customary law aspect, Islamic law aspect, regional aspect, international aspect and other aspects. In fact, meanwhile, there is rapid development in the community with regard to business transactions that are also followed with contract law development. Therefore, amendment is needed for the Indonesian contract law to adapt to the people’s need for law, and this change agenda is also addressed to updating the contract law.

Civil law reform, especially contract law, is deemed very important for Indonesia, because based on field fact, people do their business contract by applying contract law that is not yet regulated in the contract law in KUHPerdata; thus, new contract law is needed that regulates important matters related to sources other than agreement and law.

It is very important to conduct this research to review government policy in Indonesian contract law that still uses the contract law inherited from Dutch product (BW) and review what regulations should have been adjusted to current development of contract law. The novelty of this research is that new rules will be found in Indonesian contract law. This research is different from previous researches conducted by Sigit Irianto (2013) and Deviana Yuanitasari (2020), that discuss only on contract law development related only to the good faith principle.

This paper stimulates methodological debates and advances the research agenda for qualitative research about time and temporality in organizing processes. It develops a framework for studying the temporal in organizing that contributes by: (1) providing an overview to prepare for and navigate various methodological challenges in this regard, (2) offering inspiration for relevant solutions to those challenges and (3) posing timely questions to facilitate temporal reflexivity in scholarly work.

Based on a literature review of studies about temporality in organizing processes, the authors develop a framework of well-acknowledged methodological challenges, dilemmas and paradoxes, and pose timely questions with which to develop potential solutions for research about organization and time.

The framework of this study offers a synthesis of methodological challenges and potential solutions acknowledged in the organization studies literature. It consists of three interrelated dimensions of methodological challenges to studying temporality in organizing processes, namely: empirical, analytical and representational challenges. These manifests in six subcategories: empirical cases, empirical methods, analytical concepts, analytical processes and coding, representing researchers’ temporal embeddedness and representing multiple temporalities.

This paper allows scholars to undertake a more ambitious, collective methodological discussion and sets an agenda for studying the temporal in organizing. The framework developed stimulates researchers’ temporal reflexivity and inspires them to develop solutions to specific methodological challenges that may emerge in their study of the temporal in organizing.

This work aims to deal with a comprehensive review of design methods for aircraft directional stability and vertical tail sizing. The focus on aircraft directional stability is due to the significant discrepancies that classical semi-empirical methods, as USAF DATCOM and ESDU, provide for some configurations because they are based on NACA wind tunnel (WT) tests about models not representative of an actual transport airplane.

The authors performed viscous numerical simulations to calculate the aerodynamic interference among aircraft parts on hundreds configurations of a generic regional turboprop aircraft, providing useful results that have been collected in a new vertical tail preliminary design method, named VeDSC.

The reviewed methods have been applied on a regional turboprop aircraft. The VeDSC method shows the closest agreement with numerical results. A WT test campaign involving more than 180 configurations has validated the numerical approach.

The investigation has covered both the linear and the non-linear range of the aerodynamic coefficients, including the mutual aerodynamic interference between the fuselage and the vertical stabilizer. Also, a preliminary investigation about rudder effectiveness, related to aircraft directional control, is presented.

In the final part of the paper, critical issues in vertical tail design are reviewed, highlighting the significance of a good estimation of aircraft directional stability and control derivatives.

Recent work has demonstrated that stochastic models, incorporating a time parameter, have great potential value for library management in predicting future use of library materials, particularly in the presence of ageing of materials. In this paper a simple empirical Bayes method is presented which avoids the analytic complexity of earlier models and which may therefore be more attractive to the library manager. In particular, the ‘prediction profile’ is advocated as a useful additon to the manager's toolbox.
