Purpose: The theory of constraints (TOC) drum-buffer-rope methodology is appropriate when managing a production plant in complex environments, such as make-to-order (MTO) scenarios. However, some difficulties have been detected in implementing this methodology in such changing environments. This case study analyses a MTO company to identify the key factors that influence the execution of the third step of TOC. It also aims to evaluate in more depth the research started by Lizarralde et al. (2020) and compare the results with the existing literature.Design/methodology/approach: The case study approach is selected as a research methodology because of the need to investigate a current phenomenon in a real environment.Findings: In the case study analysed, the protective capacity of non-bottleneck resources is found to the key factor when subordinating the MTO system to a bottleneck (BN). Furthermore, it coincides with one of the two key factors defined by the literature, namely protective capacity and protective inventory.Originality/value: The three key contributions of this study focus on the MTO environment as follows. The first is about identifying the key factors in subordinating the system to the BN (step 3, TOC) according to the existing literature which have been identified through a systematic literature review. The second focuses on identifying the key factors in subordinating the system to the BN through a case study. Finally, the last contribution compares the results obtained in the case study with those obtained in the literature review.

While Point-of-Interest (POI) recommendation has been a popular topic of study for some time, little progress has been made for understanding why and how people make their decisions for the selection of POIs. To this end, in this paper, we propose a user decision profiling framework, named PROUD, which can identify the key factors in people's decisions on choosing POIs. Specifically, we treat each user decision as a set of factors and provide a method for learning factor embeddings. A unique perspective of our approach is to identify key factors, while preserving decision structures seamlessly, via a novel scalar projection maximization objective. Exactly solving the objective is non-trivial due to a sparsity constraint. To address this, our PROUD adopts a self projection attention and an L2 regularized sparse activation to directly estimate the likelihood of each factor to be a key factor. Finally, extensive experiments on real-world data validate the advantage of PROUD in preserving user decision structures. Also, our case study indicates that the identified key decision factors can help us to provide more interpretable recommendations and analyses.

PurposeThis study aims to investigate and model the complex dynamics of innovation enablers in construction projects aiming to develop a framework identifying actions for clients to promote innovation.Design/methodology/approachThrough a comprehensive literature review, a conceptual model was previously derived to explain the client-driven enablers in promoting innovation. This was tested using the data from 131 Australian construction projects. Statistical analysis was conducted on the data using factor analysis and correlation analysis to test the model, which was validated using the case study approach. The testing and validating aspects are explained in this paper.FindingsThe constructs of the recommended model are idea harnessing, relationship enhancement, incentivization and project team fitness.Research limitations/implicationsThe difficulty of analyzing the complex dynamics happening within projects in relation to innovation has been a barrier to progress research in this area. The introduction of this model would pave the way for researchers to explore this area with ease.Originality/valueAs revealed in the detailed literature review undertaken, this is the first time that a comprehensive study has been conducted to identify client-led innovation enablers for construction projects. The results would benefit industry practitioners to achieve enhanced project outcomes in construction projects through innovation.

This study considers the linkage between micro-sized enterprises and other organizations, especially universities, in relation to the innovation process. The focus of the research is on non-start-up enterprises in Wales and how they develop their products. The research methodology adopted is a thematic literature review and the case study approach. The findings demonstrate that there are additional barriers to innovation in terms of legislation and regulation when micro-sized enterprises endeavour to overcome their knowledge gap through collaborating with universities. It is noted that there has been minimal research examining the knowledge gap encountered by micro-sized enterprises and how they attempt to overcome the barriers to collaborating with universities.

Intervention Sustainability

This study identifies factors that support the sustainability of interventions implemented to enhance responses to alcohol and other drug misuse in Australian community health settings. Eight completed projects that had received time-limited funding were sampled to reflect a mix of project types, contexts and success in meeting funding objectives. Projects were investigated using a case study approach involving thematic analysis. Project records were analysed and interviews were conducted with stakeholders to identify intervention elements that continued after funding ceased, and factors that supported this sustainability. Key factors identified were: embedding changes in the operations of the agency; filling a critical gap in the sector; building support from key individuals and agencies; and planning realistically for future ownership. We argue that complexity theory provides a framework to understand both the context-bound nature of intervention sustainability and differences within the literature as to how sustainability is typologised. Each factor associated with intervention sustainability identified in this study reflects an astute understanding of project context and a capacity to adapt. These factors could assist people designing interventions with time-limited funding to maximise ongoing impact of interventions. They should optimally be implemented within an overall approach of flexibility and sensitivity to context.

Abstract In this paper, we focus on inventory management in a manufacturing company in China. This study aims to identify the key factors that influence inventory management practices, investigate efficient and effective inventory management approaches, and examine the impact of supplier cooperation on supply chain improvement. A case study approach is used to identify the key factors that influence inventory management in a factory. Efficient and effective inventory management practices are derived from the case study and may provide practical guidance for foreign manufacturers in China. This study provides a valuable tool for identifying the key factors in inventory management which can be applied to similar problems encountered in actual manufactories.

Optimal Approach

Purpose Research has shown that non-governmental organizations (NGOs) often fail to appreciate that in their market, donors represent clients. Moreover, the unstable income characteristics of NGOs emphasize the importance of conducting market analysis specific to such organizations. The purpose of this paper is to identify key factors that influence fundraising success for mental health NGOs and determine the most advantageous fundraising approach based on a mixed-methods study that encompass a literature review, two surveys and a case study. Design/methodology/approach Based on a structured literature review, the most important factors affecting NGO fundraising are unified into a decision-making framework. This framework is tested using a triangulation approach by combining quantitative and qualitative methods. The former based on a general survey and the latter based on a case study. Findings The results highlight 15 key factors determining the optimal approach for mental health NGOs when fundraising in Denmark. Practical implications The decision-making framework can be used to assess the most advantageous fundraising approach based on a variety of internal and external circumstances. Originality/value While private firms develop exhaustive market analyses, NGOs often lack analyses to cope with fluctuating environments and changing customer needs. This paper addresses this gap by identifying key factors that determine an optimal fundraising approach and proposes a novel decision-making framework for practitioners.

This born-digital article examines the multimodal academic publication Pathfinders (Moulthrop and Grigar). Through a combination of interviews with readers and the author, textual analysis of the book, and literature review of Scalar, I trace the affordances of the platform, appropriation by scholars, the media text, and readership of Pathfinders. I distill themes that are key in the multimodality of the book, including platform adoption, institutional embedding, technological context and research values. Throughout the article, which is also written on Scalar, I reflect on my own use of Scalar and the various considerations that come with it in terms of software sustainability, accessibility, and transparency of research context. I conclude with a reflection on the media specificity of Scalar as an academic platform.

Banyak gitaris yang memainkan gitar klasik dan gitar elektrik secara beriringan. Namun banyak dari mereka yang merasakan bahwa kedua teknik permainan gitar tersebut agak bertolak belakang dan saling mempengaruhi. Tujuan penelitian ini adalah untuk menjembatani antara teknik permainan gitar klasik dan gitar elektrik. Metodologi yang digunakan dalam penelitian ini adalah pendekatan studi kasus, kajian pustaka dan karya dengan memanfaatkan jurnal online, buku serta partitur karya. Hasilnya adalah teknik permainan gitar klasik dan elektrik yang agak bertolak belakang tersebut dapat diatasi salah satunya dengan cara memainkan etude. Etude tersebut terdiri dari teknik-teknik permainan yang khas terdapat pada gitar klasik dan gitar elektrik. Selain itu teknik-teknik permainan yang khas tersebut dapat dikombinasikan sehingga menghasilkan teknik hybrid antara gitar klasik dan gitar elektrik. Dengan tujuan, gitaris klasik dan gitaris elektrik yang memainkan kedua gitar tersebut secara beriringan akan mengetahui teknik-teknik permainan yang khas terdapat pada gitar klasik dan gitar elektrik. Serta mengaplikasikan teknik hybrid tersebut kedalam permainan gitarnya, sehingga gitaris bisa melatih kedua teknik permainan gitar tersebut secara bersamaan, tanpa meninggalkan salah satunya.Many guitarists play classical guitar and electric guitar simultaneously. But many of them feel that the two guitar playing techniques are somewhat contradictory and influence each other. The purpose of this study is to bridge the technique between classical guitar and electric guitar. The methodology used in this research is a case study approach, literature review and works by utilizing online journals, books and scores of works. The result is that the classical and electric guitar playing techniques are somewhat contradictory, one of which can be overcome by playing etude. Etude consists of techniques that are typical of the game found on the classical guitar and electric guitar. In addition, these typical playing techniques can be combined to produce a hybrid technique between a classical guitar and an electric guitar. With the aim, the classical guitarist and the electric guitarist who play both guitars together will know the game techniques that are typical found on the classical guitar and the electric guitar. As well as applying these hybrid techniques into his guitar playing, so the guitarist can practice both guitar playing techniques simultaneously, without leaving one of them.

Mobile Phone Usage

In emerging markets, the amount of mobile communication and the number of occasions mobile phones are used are increasing. More and more settings appropriate or not for mobile phone usage are being exposed. Although prohibited by many governments, there is evidence that use of new mobile devices while driving are somehow becoming current everyday practice, hence legitimatizing usage for many users. Dominant dangerous behavior in the absence of enforced legal framework is being deployed and has become routine for many m-users. This chapter adopts a qualitative case study approach (20 cases) to examine the public transport drivers’ motives, logic and legitimacy processes. The question which these issues raise in the light of advancing m-technologies is: How do, in the context of emerging market, undesired emerging routines enactment get to be reflected upon and voluntarily disregarded to maximize the benefits of m-technologies while minimizing their drawbacks? Findings point out at multiple motives for usage including external social pressure through the ubiquitous 24/7 usage of m-technology, lack of alternative communication protocol, real time need for action and from an internal perspectives boredoms, lack of danger awareness, blurring of the boundaries between personal and business life and lack of job fulfillment are uncovered as key factors. As secondary dynamic factors such as education, drivers work’ histories, impunity, lack of strong consumer opposition appear central in shaping the development of the routines.
