Optimal pricing strategies for Manufacturing-as-a Service platforms to ensure business sustainability
Manufacturing as a Service (MaaS) is a service which delivers manufactured products by connecting its network of suppliers with its customers on a digital platform. The long term sustainability of the MaaS platforms depends on their pricing strategy and whether they can generate sufficient volume from customers and encourage suppliers to do business with them. The objective of the paper is to develop optimal prices which a MaaS platform can charge to maximize its own profit as well as joint profit for itself and its supplier. Game theoretic models based on Hotelling's model are developed to determine the prices. We consider scenarios when the platform charges and does not charge subscription fees. We also determine conditions for the supplier to join the platform. Our models are motivated by real problems faced by a MaaS platform and have been validated using data provided by the platform. The models, the conditions developed and the insights obtained by validating the models using real data provide guidance to MaaS platforms to improve their business sustainability. The paper thus shows that MaaS platforms, when successfully designed, with appropriate pricing models can create an effective and economically sustainable business ecosystem
A Conceptual Framework of Business Model Emerging Resilience
In this paper we introduce an environmentally driven conceptual framework of Business Model change. Business models acquired substantial momentum in academic literature during the past decade. Several studies focused on what exactly constitutes a Business Model (role model, recipe, architecture etc.) triggering a theoretical debate about the Business Model’s components and their corresponding dynamics and relationships. In this paper, we argue that for Business Models as cognitive structures, are highly influenced in terms of relevance by the context of application, which consequently enriches its functionality. As a result, the Business Model can be used either as a role model (benchmarking) or a recipe (strategy). For that purpose, we assume that the Business Model is embedded within the economic (task) environment, and consequently affected by it. Through a typology of the environmental impact on the Business Model productivity, we introduce a conceptual framework that aims to capture the salient features of Business Model emergent resilience as reaction to two types impact: productivity constraining and disturbin
Estimating the wider value generated by UNESCO’s designations in the United Kingdom
In September 2015, the United Nations General Assembly adopted a set of objectives related to promoting and supporting sustainable development around the globe through education, human knowledge, communication and culture. These objectives are commonly known as the Sustainable Development Goals (SDGs) and are an inter-dependent set of 17 goals that 195 Member States have agreed to achieve by 2030. As a specialised agency of the United Nations, and the global lead on education, UNESCO has a vital role to play in delivering the SDGs. UNESCO’s global network of 'designations', including World Heritage Sites, Biosphere Reserves, UNESCO University Chair Programme, and Global Geoparks, also play an essential role in promoting and supporting local sustainable development and achieving the SDGs. However, the different geographic, cultural and political regimes under which UNESCO designations are called to operate, pose significant challenges for the network to effectively be managed and contribute towards the SDGs. Moreover, the heterogeneity of organisational structures and boundaries in terms of efficiency, power and competence, prevents UNESCO designations "value-added" activities from reaching their full potential. We performed a survey of 74 designations in England, Northern Ireland, Scotland and Wales. Drawing from the business model component framework, our research aims to i) identify value generating configurations of organisational structures that transcend designations’ type, ii) estimate the value generated by the designation and their contribution to UNESCO’s SDGs; and, iii) develop a framework that can be used by national governments to make sense of UNESCO’s value generated activities. The framework can help UNESCO’s National Commissions to improve the efficient management of the designation’s global network and allow countries with different levels of economic and societal development to cooperate to tackle contemporary global challenges
A strategic roadmap for BM change for the video-games industry
The global video games industry has experienced and exponential growth in terms of socioeconomic impact during the last 50 years. Surprisingly, little academic interest is directed towards the industry, particularly in the context of BM Change. As a technologically intensive creative industry, developing studios and publishers experience substantial internal and external forces to identify, and sustain, their competitive advantage. To achieve that, managers are called to systematically explore and exploit, alternative BMs that are compatible with the company’s strategy. We build on empirical analysis of the video-games industry to construct a Toolkit that i) will help practitioners and academics to describe the industrial ecosystem of BMs more accurately, and ii) use it a strategic roadmap for managers to navigate through alternatives for entrepreneurial and growth purposes

Surface modification of a polyethersulfone microfiltration membrane with graphene oxide for reactive dyes removal
Polyethersulfone microfiltration membranes (mPES) were modified with polyethilenimine (PEI) and graphene oxide (GO) by layer-by-layer self-assembly method via electrostatic interaction using a pressurized filtration system. The high positively charge of PEI allowed it to be easily assembled on the polyethersulfone substrate, and also to receive the negative layer of GO. Several techniques were applied to characterize the modified membranes (i.e. ATR-FTIR, SEM, water angle contact and zeta potential), and proved that the modification was successfully achieved. The effect of PEI and GO concentrations in the modification was investigated, and the best performance of all membranes was achieved with a Blue Corazol (BC) dye rejection of 97.8% and a pure water permeability of 99.4 L m−2 h−1 bar−1. The membrane also presented a flux recovery ratio of >80% after being hydraulically cleaned for 30 min. Moreover, the membrane performance was evaluated in terms of rejection of BC dye in a real dye bath wastewater, and an excellent performance with a maximum rejection rate of 96% was observed. Therefore, the proposed study may provide an efficient alternative to feasible the use of microfiltration membranes, by modifying them, in order to improve its surface characteristics and its filtration capacity, aiming to apply it in the removal of dyes of textile industries wastewater.This work was funded by the Fundação para a Ciência e a Tecnologia (FCT), project n° POCI-01-0145-FEDER-007136 (UID/CTM/00264/2013).

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis
BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.
