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.

Nowadays, to meet people’s needs in daily life for drinking water, many companies provide bottled drinking water. As this industry grows and more competition occurs, the companies should know the aspects that influence people to buy the products that are bottled drinking water. Although this increase in several bottled water producers can be attributed to market demand and technology modernization, the fact that consumers migrate from one brand to another is significant and indicates that there are factors that affect the consumer’s decision when choosing the bottled water brand. The aim of this paper is to identify and analyze the factors that influence consumers the most when choosing a bottled water brand in the market, using Kosovo as a case study. To define factors based on the consumer’s preferences and valuations of the importance, the principal component analysis was applied based on a correlation matrix, using a component extraction method with a varimax rotation and a Kaiser-Meyer-Olkin adequacy test. The findings show that the consumer’s decision is influenced mostly by six key factors, namely quality, marketing, consumer perception, price, preference and practicality. The research provides new insights into the bottled water manufacturing industry and marketers in positioning themselves in a competitive environment.

The selection of a rubber compound has a determining influence on the final characteristics of rubber-metal springs. Therefore, the correct selection of a rubber compound is a key factor for development of rubber-metal vibration isolation springs with required characteristics. The procedure for the selection of the rubber compound for vibration isolation of rubber-metal springs has been proposed, so that the rubber-metal elements have the necessary characteristics, especially in terms of deflection. The procedure is based on numerical simulation of spring deflection with Bergström-Boyce constitutive model in virtual experiment, with a goal to determine which parameters of the constitutive model will lead to spring required deflection. The procedure was verified by case study defined to select rubber compound for a rubber–metal spring used in railway engineering.

In the attempt to study Light Rail Transit (LRT) systems, and their necessary underlying components, such as Park and Ride (P&R) sub-systems, this article aims to showcase the importance of land-use as a criterion in the selection of trip starting locations (i.e., points), that can potentially be used as the basis for quantitative studies on LRT and P&R systems. In order to achieve this goal, a method is introduced for the selection of locations that produce P&R mode trips based on the land-use attributes of sub-zones or neighborhoods, as they are included in Sustainable Urban Mobility Plans (SUMPs). Those land-use attributes are utilized as sub-criteria for the classification and valid selection of trip starting locations out of a broader dataset of available locations. As a second supportive technique that needs to be utilized for this study, an algorithm is introduced, which allows us to test the effectiveness of the method and the importance of land use as a criterion. The algorithm enables the calculation and comparison of the attributes of the trips to be followed by P&R mode users starting from selected trip starting locations for each zone in a city and having as destinations the several available P&R facilities. Results for the methods introduced in this article are showcased based on a case study on the mid-sized city of Cuenca, Ecuador, in which, several metrics, such as traveling times considering different traffic scenarios, are examined for the potential P&R mode trips as they emerge from real-world data.

The objective of this article is to analyze the relationship between universal design and ergonomics as key factors in the design and selection of assistive products developing a comparison using the Pugh matrix. A group of users was interviewed to determine the design requirements of aid products and then, the products available in the market were evaluated to determine which could be the best. The user’s needs were identified through the evaluations among patients with rheumatoid arthritis focusing on universal and ergonomic design and sixty-nine assistive products were selected. The Pugh matrix was applied to compare and evaluate them based on design criteria. The results indicate that accessibility products must be more efficient in terms of reach, grip, apprehension, pincer grasp, materials, and the force required to use the product. However, the aesthetics of the design was a key factor for the user to select the product and feel more comfortable when using it.

Selection of service providers in the global supply chains of today has been recognized as having a very important effect on the competitiveness of the entire supply chain. It results in achieving high quality end results (products and/or services), at reasonable cost coupled with high customer satisfaction. This article discusses the use of Fuzzy Analytic Hierarchy Process (FAHP) to effectively manage the qualitative and quantitative decision factors which are involved in the selection of providers of 3PL services under Lead Logistics Provider (LLP) environments of today. Lead logistics providers (LLP) are increasingly being banked upon to integrate the best of 3PL service providers and allow for synchronized and optimized operations. In the asset free environments of today, many a times, the LLP uses the services of the 3PL and hence the issue of reliably choosing them assumes increasingly greater significance. The fuzzy-AHP has been adequately demonstrated in literature to be an effective tool which can be used to factor-in the fuzziness of data. Triangular Fuzzy Numbers (TFN) have been deployed to make over the linguistic comparisons of criteria, sub-criteria and the alternatives. The FAHP based model formulated in this chapter is applied to a case study in the Indian context using data from three leading LSPs with significant operating leverages in the province of Uttrakhand (India). The proposed model can provide the guidelines and directions for the decision makers to effectively select their global service providers in the present day competitive logistics markets.

By the turn of the 21st century, the significance of knowledge to be the key factor in urban and regional development is well established. However, it has been only recently that attempts have been made to identify the specific mechanism and institutional relationships, through which knowledge-based development takes place. In this regard, very little consideration has been given to the ways that different levels of knowledge-based development communicate to each other. This chapter examines the mutual interaction between knowledge-based development in local and regional level in two different sections. The first section builds upon the third wave of economic development supporting the growth of cluster of related firms and relates it to an empirical case study of knowledge-based community development in Queensland- Australia. It concludes that knowledge-based local developments do not evolve without a regional support network. The second section reviews the “Triple Helix” of university–industry–government collaboration as the basis of knowledge-based regional development in the investigated case study. This review determines the central role of local community as an innovation base for the interaction among the key factors, and suggests a promotion for a Quadruple Helix Model where community works alongside business, university and government in the new economy.

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.

Nuclear technology remains a critical point of interest for many states in the post-Cold War era either as they enhance their weapons arsenal and/or advance on the peaceful uses of nuclear technology. This can become problematic for smaller states that greater powers are suspicious of. Using Bolivia as a case study this article seeks to understand how Bolivia has accommodated the three pillars of the Nuclear Non-Proliferation Treaty into its foreign policy in an attempt to elude suspicion and develop atoms for peace. This investigation is undertaken by using desktop research that seeks to understand Bolivia’s stances toward nuclear weapons as well as its desires (and how it seeks to fulfil these desires) of obtaining peaceful nuclear technology. The findings suggest that Bolivia is fully compliant with the Nuclear Non-Proliferation Treaty, and is not discriminatory in the selection of its partners both at home and abroad as long as they share mutual interests and yield the best possible outcome for Bolivia. Furthermore, this research also reveals that Bolivia has been tactful in its alliance and partner formation so that those chosen help to elevate Bolivia’s international status. In conclusion, it is unquestionable that Bolivia has created some remarkable opportunities for itself thanks to its tactfulness; however, Bolivia also faces some key domestic economic realities that could hinder its ambitions.

Accuracy of hydrogeological and geotechnical investigation in place of shaft sinking is a key factor for selection of sinking method and design of the shaft lining. The following work presents the influence of the rising level of accuracy of geological data gathered in the area of shaft sinking in the Silesian Coal Basin and technical projects of shaft lining and technology of its sinking, which have been changing over the years. The initial project of the shaft was repeatedly modified. Each modification eventuated in rising requirements for the shaft lining, such as increasing its thickness or changing concrete class. It has become necessary to use additional methods of reinforcing rock mass around the shaft.
