The possible evolution of facility management (FM) in industrial districts, which characterise Italian industrial system, is analysed. The paper investigates structural features of industrial districts, mainly formed by small sized enterprises, and how they influence the attributes of the FM market. An aggregation matrix is introduced to identify technical opportunities such as replicated, centralised and distributed facilities and management for industrial districts. A positioning matrix for a district‐oriented FM is proposed, allowing FM providers to seize technical opportunities and to reap economies of scale and scope. Requisites and obstacles to the evolution of potential FM providers towards more competitive positions are outlined. The role of co‐operation with and among potential clients, in particular, together with information, is clarified. Considering the client’s perspective, the paper describes the forms of competitive advantage that can be gained through a district‐oriented FM by single enterprises and by an industrial district as a whole.

This paper aims to give a picture of maintenance management in Italian manufacturing firms supported by empirical evidence. The purpose is also to highlight how far maintenance performance and strategies are influenced by context and which measures and goals are within reach of small‐sized firms.

Frameworks for describing maintenance management and strategies derived from literature were reviewed and used to develop a questionnaire. A survey‐based empirical research involving a sample of 100 manufacturing firms was performed. Non‐parametric statistics are applied to highlight correlations and dependencies between contextual variables, maintenance strategies and performance.

Maintenance performance hardly seems a matter of size, while many elements of strategy certainly are. Some elements of strategy, in particular planning and control elements, seem to have little impact on performance. By contrast, an enhanced use of preventive maintenance and, above all, of condition‐based maintenance is demonstrated to be a highly effective action for maintenance improvement applicable to firms of all size.

The research may help managers to decide on maintenance strategic variables by deducing from the experience of many different firms whether, and how, strategies affect maintenance performance.

Besides giving a country's portrait, the empirical research addresses the links between strategies, context and performance, thereby understanding strategy in a broad sense and not just in terms of maintenance policies and concepts. In particular, the maintenance practices of small enterprises with fewer than 50 employees are studied, which has rarely been done in the literature.

The objective of this study is to highlight the questions arising in the design of district heating and cooling systems (DHCSs) in a distributed generation context and to present a model to help find cost‐effective solutions.

Literature on energy systems optimisation is reviewed and a mixed integer programming model for decentralized DHCSs design is developed and applied to two real case studies.

Distributed cooling generation partly coupled with distributed cogeneration and DH is the preferred solution in the examined areas. The optimal configurations, with special reference to network sizing and layout, significantly depend on heating demand profiles and energy prices.

Interdependencies between energy units sizing and network layout definition should be considered. Obtaining more robust and reliable network configurations should be the objective of future modelling efforts.

Despite the growth of distributed energy conversion, designers often rely on centralized concepts in order to reap economies of scale. The presented model helps in discovering less usual solutions representing the most profitable option.

Combining and comparing central and distributed production of heat and cooling under consideration of network costs.

The mechanisms of knowledge acquisition and their impact on innovation are particularly relevant in the context of rapidly growing emerging markets. The purpose of this paper is to investigate the relationship between firm acquisition characteristics and post-acquisition knowledge exploration and exploitation in the Chinese domestic acquisition market.

By using patent and company data of 188 domestic Chinese deals completed between 2002 and 2013, the paper replicates the measurements and analytical methods of the US-based study by Phene, Tallman and Almeida (2012) to address the acquirer’s opportunity to explore and/or exploit external knowledge, its ability to absorb and effectively assimilate such knowledge and thus establish innovations in new technologies.

The paper finds support for a positive effect of knowledge uniqueness of the target on the bidder’s post-acquisition exploration. The findings also support that the post-acquisition exploitation is facilitated by the commonality of technological knowledge between the bidder and the target, a result that, although expected, was not be supported in the US-based study.

This paper qualifies the generalizability of US-based findings about post-acquisition exploration and exploitation in the context of China. It also responds to the call for China-focused knowledge management research by capturing innovation capability building by Chinese firms through domestic acquisitions. Finally, it contributes to the nascent literature on replication in management studies.

Over‐the‐counter (OTC) weight management products are popular with the public. Manufacturers frequently claim beneficial effects of these products, however current legislation does not compel them to support these claims with research. This paper identifies the key ingredients of OTC weight management products and evaluates evidence for their safety and efficacy.

Using Medline, published evidence on key ingredients and formulations was gathered. Contact was also made with manufacturers to ascertain whether unpublished data were available. All studies were assessed for quality. The efficacy and safety of the ingredients and formulations were then reviewed.

The results showed little evidence for most weight loss claims, with the exception of a formulation containing Yerba maté, Guarana and Damiana. In addition, studies on pyruvate, conjugated linoleic acid, and Citrus aurantium demonstrated positive effects on weight loss, suggesting that they may be useful in future formulations. Safety implications were noted for ephedrine.

Better labelling and supporting literature should be introduced by reputable manufacturers and retailers to help the public assess the efficacy of weight loss aids.

Given the popularity of self‐treatment, there is a need for more manufacturers to submit their products to impartial clinical trials. OTC weight management products could be useful in addressing obesity, but most still need scientific evidence to demonstrate safety and effectiveness.

This review reviews the available evidence on ingredients of OTC weight management products, providing a unique guide to what works, and what doesn't.
