The environmental impact of road construction and rehabilitation can be associated with the increase of greenhouse gas (GHG) emissions, which are highly related to climate change. Consequently, departments of transportation have recently focused on the development and implementation of tools to evaluate the performance of projects and minimize GHG emissions. An example is the use of life cycle assessment (LCA) to analyze and quantify the environmental impact of a product, system, or process, from cradle to grave. In this regard, the present case study quantifies the carbon footprint associated with the construction of the La Abundancia–Florencia highway, located in the province of San Carlos in Costa Rica. The analysis is also intended to generate consciousness both in the public and private sectors on the environmental impacts of road construction. After an LCA study, it was determined that the construction of the hot mix asphalt (HMA) layer generates a carbon footprint of 65.8 kg of CO2e per km of road. In addition, it was evident that HMA production generates the greatest environmental impact, among all the considered LCA production and construction stages, with a GHG contribution of 38% to 39% from bitumen only. Consequently, special attention to HMA production is required in order to minimize GHG emissions.

(1) Background: Black plastics pose a general problem in sustainability issues, as the recycling is hampered by the black colour disguising the type of plastics in the NIR scanner on the garbage sorting belt, as the black colour absorbs NIR radiation. Sorting flower/plant pots suffer from their additional soil contamination in the strive for sustainable flower production in horticulture. As these black plastic flowerpots are currently rarely recycled, a study was instigated of reusing them based on Heino Schwarz’s innovative idea. (2) Methods: In the first step, the carbon footprint was calculated for the flowerpots of two sizes employed in the nursery, their customised production from virgin polypropylene and the delivery from the Netherlands to the nursery in Bavaria. In step 2, the carbon footprint was calculated based on PAS 2050-1 for the number of flowerpots in circulation and return rates in 2019 and in 2020 to assess the GHG saved by the innovation. (3) Results: The innovative concept of Heino Schwarz is a discount on returning the customised used flowerpots, with a 40% increase from 24,533 returned flowerpots in 2019 to 39,797 in 2020. This shows the increasing acceptance and environmental awareness of the consumer and the great success. (4) Conclusions and outlook: The present case study has shown that innovative approaches such as discounts for reused/returned flowerpots of the Schwarz nursery can save 3.85–4.56 t CO2eq, a valuable contribution to reducing GHG emissions, creating environmental awareness among the consumers and building a close B2C relationship. The amount of CO2eq saved is equivalent to ca. 40% of the annual carbon burden of a European/German citizen or ca. 23,000 km driven in a private vehicle, the average mileage driven privately in two years.

<p>This article tackles the means of theatre space reconfiguration in the apartment theater (<em>lorgean theater</em>), simultaneously analyzing the relation between public and private specific to this form of art. Structured around both a theoretical analysis and a qualitative empirical investigation, this paper emphasizes the traits of the theatre space as component of an artistic product received by the audience, and its value in the process of artistic production, within the theatre sector. The case study of <em>lorgean theater, </em>including a participant observation and an individual interview, enables the understanding of these two aspects of the spatial configuration, emphasizing its hybrid nature in terms of spatial configuration and the public-private relation as well as the act of reappropriation of the domestic space through an alternative practice of theatre consumption.</p>

The chapter will be a case study from an Ordoliberal perspective of the conception, implementation and policy output of the newly created Private Council of Competitiveness (PCC) in Guatemala, a country wracked by mistrust of the public sector by the private sector. The PCC was founded as a private sector initiative, in conjunction with academia, to work with the government to spawn new efforts aimed at augmenting Guatemala's national competitiveness, by fomenting innovation, entrepreneurship and closer ties between academia and the public and private sectors. The chapter utilizes first hand interviews with the members of the PCC and key public sector players, academics, and other top representatives from the private sector to show how working together built the trust necessary to make the PCC a successful working body with the potential to produce important initiatives in matters of competitiveness, innovation and entrepreneurship.

Purpose Neo-liberal “reform” has in many countries shifted services across the boundary between the public and private sector. This policy re-opens the question of what structural and managerial differences, if any, differences of ownership make to healthcare providers. The purpose of this paper is to examine the connections between ownership, organisational structure and managerial regime within an elaboration of Donabedian’s reasoning about organisational structures. Using new data from England, it considers: how do the internal managerial regimes of differently owned healthcare providers differ, or not? In what respects did any such differences arise from differences in ownership or for other reasons? Design/methodology/approach An observational systematic qualitative comparison of differently owned providers was the strongest feasible research design. The authors systematically compared a maximum variety (by ownership) sample of community health services; out-of-hours primary care; and hospital planned orthopaedics and ophthalmology providers (n=12 cases). The framework of comparison was the ownership theory mentioned above. Findings The connection between ownership (on the one hand) and organisation structures and managerial regimes (on the other) differed at different organisational levels. Top-level governance structures diverged by organisational ownership and objectives among the case-study organisations. All the case-study organisations irrespective of ownership had hierarchical, bureaucratic structures and managerial regimes for coordinating everyday service production, but to differing extents. In doctor-owned organisations, the doctors’, but not other occupations’, work was controlled and coordinated in a more-or-less democratic, self-governing ways. Research limitations/implications This study was empirically limited to just one sector in one country, although within that sector the case-study organisations were typical of their kinds. It focussed on formal structures, omitting to varying extents other technologies of power and the differences in care processes and patient experiences within differently owned organisations. Practical implications Type of ownership does appear, overall, to make a difference to at least some important aspects of an organisation’s governance structures and managerial regime. For the broader field of health organisational research, these findings highlight the importance of the owners’ agency in explaining organisational change. The findings also call into question the practice of copying managerial techniques (and “fads”) across the public–private boundary. Originality/value Ownership does make important differences to healthcare providers’ top-level governance structures and accountabilities and to work coordination activity, but with different patterns at different organisational levels. These findings have implications for understanding the legitimacy, governance and accountability of healthcare organisations, the distribution and use power within them, and system-wide policy interventions, for instance to improve care coordination and for the correspondingly required foci of healthcare organisational research.

Companies are gradually becoming conscious about the necessity of reducing their environmental impact and adopting low-carbon strategies in order to cope with increasing institutional and social demands. However, remaining competitive while reducing the environmental impact and improving the corporate image requires adopting sophisticated mechanisms boosting eco-efficiency and keeping costs tight. Material Flows Cost Accounting (MFCA) is an instrument that allows the monitoring of, measurement of, and accounting for physical and monetary processes along the production process. If extended to the supply chain, and applied to the energy usage and CO2 emissions, it allows one to account for the Carbon Footprint (CF) of a company and its products at any given stage of the value chain. The current paper presents a case study developed under the framework of a three-year project to introduce an energy use and carbon emissions monitoring and accounting system in a large winery company in Spain, based on the MFCA approach and CF accountability. Including the supply chain of the company and the whole farming cycle of its main input, the case study presents the method and phases adopted to implement the project, its direct and indirect results and outcomes, and the conclusions that can be extracted, which may be inspirational for practitioners and scholars envisaging similar projects.

Objective: In Australia, mental health services are delivered by a complex web of publicand private-sector providers. There is a growing recognition that linkages between these groups are not optimal, and a concern that this may lead to poor outcomes. This paper illustrates a conceptual framework for developing, implementing and evaluating programmes concerned with linkages. Method: Drawing on theoretical and practical literature, this paper identifies different levels of integration, issues in evaluating programmes to address poor linkages, and features of useful evaluations. Within this context, it describes the method by which the Public and Private Partnerships in Mental Health Project (Partnership Project) is being evaluated. Conducted by St Vincent's Mental Health Service and The Melbourne Clinic, this is one of several Demonstration Projects in Integrated Mental Health Care funded under the National Mental Health Strategy. Results: Collaboration is hard to conceptualize and collaborative programmes usually have many players and components, and tend to operate within already-complex systems. This creates difficulties for evaluation, in terms of what to measure, how to measure it, and how to interpret findings. In spite of these difficulties, the illustrative example demonstrates a model for evaluating collaborative programmes that is currently working well because it is strongly conceptualized, descriptive, comparative, constructively sceptical, positioned from the bottom up, and collaborative. Conclusions: This model, or aspects of it, could be extended to the evaluation of other mental health programmes and services that have collaborative elements.

This paper discusses results from a research study in the design and implementation of information documents and products in the Australian Taxation Office (ATO). It presents a composite ethnographic and case study analysis of user-centred information design practices at the ATO from 2001-2005, and shows that the ATO has been an active proponent of user centred design practices in developing business information documents and products for an extended period of time, while also identifying potential opportunities to improve business simulation, design and product construction. The article highlights that user-centred design principles may have broad based application in both the public and private sectors.

The concept of sustainability in the road construction sector is a complex issue because of the various steps that contribute to the production and release of greenhouse gas (GHG) emissions. Addressing this issue, the European Commission has put various policy initiatives in place to encourage the construction industry to adopt circular economy (CE) and industrial symbiosis (IS) principles e.g., the use of recycled materials. Cooperativa Trasporti Imola (CTI), a company located in the Emilia-Romagna region (Italy), has been chosen for the current case study to examine practices, management, and the industrial symbiosis network among various companies in the road construction and rehabilitation sector. In this regard, the use of steel slags, obtained by an electric arc furnace (EAF), and reclaimed asphalt pavement (RAP), obtained by the deconstruction and milling of old asphalt pavement have been investigated. Two mixtures of recycled hot Mix Asphalt (HMA) i) were prepared incorporating different recycled material percentages for the wearing and binder course, respectively, ii) were characterized in terms of size distribution, strength modulus and volumetric properties, iii) and finally were compared to the performances of two mixtures entirely designed by virgin materials for the wearing and binder course, respectively. Therefore, the Life Cycle Assessment (LCA) tool was chosen to evaluate the environmental impacts that affect the designed road life cycle. The results show that recycling RAP and EAF slags in a CTI batch plant provides benefits by reducing the consumption of virgin bitumen and aggregates and by reducing CO2eq emissions. Finally, practical implications on the use of recycled materials in new asphalt mixtures from a life cycle and industrial symbiosis perspective are provided.

Abstract: The Less Salt, More Life program was the first voluntary salt reduction initiative in Argentina. This article analyzes the perspectives of the stakeholders involved in this voluntary agreement between the Ministry of Health and the food industry to gradually reduce sodium content in processed foods. This exploratory case study used a qualitative approach including 29 in-depth interviews with stakeholders from the public and private sectors and identified the role of the different stakeholders and their perceptions regarding the challenges encountered in the policy process that contribute to the debate on public-private partnerships in health policies. The article also discusses the initiative’s main challenges and controversies.
