A number of literature contributions have underlined the importance of developing value-added logistics activities or VALS in order to help improve customers’ satisfaction. However, there is usually very little attention given regarding where to perform these VALS. This study aims to: (1) identify a comprehensive set of factors which may influence the location of VALS, (2) to analyze to what extent those factors influence location decisions, and (3) to distinguish the determinants behind the location choices for distribution centers and for the kind of VALS that will be developed in these distribution centers.

In this paper, we will present a conceptual framework on the locations of VALS in view of the identifying determinants for assigning VALS to logistical centers. We argue that the optimal location of VALS is determined by complex interactions between the determinants at the level of the choice of a distribution system, distribution center location factors, and different logistical characteristics regarding products.

The purpose of this paper is to analyze the process of supermarketization in the vegetable retail sector in China and its impact on food safety.

Data from food safety reports by the Chinese Food and Drug Administration (CFDA) are used to investigate the degree of vegetable safety in different value chain types. To assess the predictors of the degree of vegetable safety, a logistic regression model is applied.

Supermarketization has led to the reorganization of the vegetables provision system, through closer coordination along the supply chain and the use of secured production bases. We identify four types of vegetable value chains in China based on their form of coordination. Supermarkets improve vegetable safety even when they rely on external suppliers, but also wet markets perform significantly better than other small-scale retailers in terms of vegetable safety.

The study has expanded the knowledge of the supermarketization in urban China by collecting data from CFDA. Furthermore, the study used the theory of food value chain to understand determinant factors in securing food safety. Moreover, this study reveals that wet markets also have prospects in solving vegetable safety problems in China, especially in underdeveloped areas.

New Public Management (NPM) has increased fragmentation in municipal health and social care organizations. In response, post-NPM reforms aim to enhance integration through service integration. Integration of municipal services is important for people with complex health and social challenges, such as concurrent substance abuse and mental health problems. This article explores the conditions for service integration in municipal health and social services by studying how public management values influence organizational and financial structures and professional practices.

This is a case study with three Norwegian municipalities as case organizations. The study draws on observations of interprofessional and interagency meetings and in-depth interviews with professionals and managers. The empirical field is municipal services for people with concurrent substance abuse and mental health challenges. The data were analyzed both inductively and deductively.

The study reveals that opportunities to assess, allocate and deliver integrated services were limited due to organizational and financial structures as the most important aim was to meet the financial goals. The authors also find that economic and frugal values in NPM doctrines impede service integration. Municipalities with integrative values in organizational and financial structures and in professional approaches have greater opportunities to succeed in integrating services.

Applying a public management value perspective, this study finds that the values on which organizational and financial structures and professional practices are based are decisive in enabling and constraining service integration.

Non-uniform rational B-splines (NURBSs) are the de facto standard for representing objects in computer-aided design (CAD). The purpose of this paper is to discuss how to stick to this standard in all phases of the additive manufacturing (AM) workflow, from the CAD object to the final G-code, bypassing unnecessary polygonal approximations.

The authors use a commercial CAD system (Rhino3D along with its programming environment Grasshopper) for direct slicing of the model, offset generation and trimming. Circular arcs are represented as quadratic NURBSs and free-form geometry as quadratic or cubic polynomial B-splines. Therefore, circular arcs are directly expressible as G2/G3 G-code commands, whereas free-form paths are rewritten as a succession of cubic Bézier curves, thereby admitting exact translation into G5 commands, available in firmware for AM controllers, such as Marlin.

Experimental results of this paper confirm a considerable improvement in quality over the standard AM workflow, consisting of an initial polygonization of the object (e.g. via standard tessellation language), slicing this polygonal approximation, offsetting the polygonal sections and, finally, generating G-code made up of polyline trajectories (G1 commands).

A streamlined AM workflow is obtained, with a seamless transfer from the initial CAD description to the final G-code. By adhering to the NURBS standard at all steps, the authors avoid multiple representations and associated errors resulting from approximations.
