This paper proposes a framework for addressing challenges of joint production and energy modeling of sustainable manufacturing systems. The knowledge generated is used to improve the technological readiness of manufacturing enterprises for the transition towards sustainable manufacturing. Detailed research tasks of the framework are on the modeling of production, energy efficiency, electricity demand, cost, and demand response decision making. Specifically, the dynamics and performance measures of general manufacturing systems with multiple machines and buffers are modeled to integrate energy use into system modeling. The expressions of electrical energy efficiency and cost are then established based on the electricity pricing profile. Finally, joint production and energy scheduling problem formulations and the solution technique are discussed. New insights are acquired based on the applications of the established model in system parameter selection, rate plan switching decision making, and demand response scheduling. Appropriate implementation of this research outcome may lead to energy-efficient, demand-responsive, and cost-effective operations and thus improve the sustainability of modern manufacturing systems.

During the last few decades we have seen a rapid growth in the body of literature on climate-induced human mobility or environmental migration. Meanwhile, in-depth people-centred studies investigating people’s (im)mobility decision-making as a highly complex and sociopsychological process are scarce. This is problematic as human decision-making behaviour and responses—including their success or failure—closely align with people’s wellbeing status. In this article, elaborations around why these under-representations of research narratives and existing methods will guide us towards a solution. The article proposes a conceptual model to help fill this gap that is inspired by Michel Foucault’s power and knowledge relationship and discursive subjectivities. The conceptual idea introduced by the article offers as a replicable approach and potential way forward that can support widening empirical research in the area of climate-induced (im)mobility decision-making and wellbeing.

AbstractSmart grid (SG) is the solution to solve existing problems of energy security from generation to utilization. Examples of such problems are disruptions in the electric grid and disturbances in the transmission. SG is a premium source of Big Data. The data should be processed to reveal hidden patterns and secret correlations to extrapolate the needed values. Such useful information obtained by the so-called data analytics is an essential element for energy management and control decision towards improving energy security, efficiency, and decreasing costs of energy use. For that reason, different techniques have been developed to process Big Data. This paper presents an overview of these techniques and discusses their advantages and challenges. The contribution of this paper is building a recommender system using different techniques to overcome the most obstacles encountering the Big Data processes in SG. The proposed system achieves the goals of the future SG by (i) analyzing data and executing values as accurately as possible, (ii) helping in decision-making to improve the efficiency of the grid, (iii) reducing cost and time, (iv) managing operating parameters, (v) allowing predicting and preventing equipment failures, and (vi) increasing customer satisfaction. Big Data process enables benefits that were never achieved for the SG application.

Public health and safety concerns around the SARS-CoV-2 novel coronavirus and the COVID-19 pandemic have greatly changed human behaviour. Such shifts in behaviours including travel patterns, consumerism, and energy use, are variously impacting biodiversity during the human-dominated geological epoch known as the Anthropocene. Indeed, the dramatic reduction in human mobility and activity has been termed the "Anthropause". COVID-19 has highlighted the current environmental and biodiversity crisis and has provided an opportunity to redefine our relationship with nature. Here we share 10 considerations for conservation policy makers to support and rethink the development of impactful and effective policies in light of the COVID-19 pandemic. There are opportunities to leverage societal changes as a result of COVID-19, focus on the need for collaboration and engagement, and address lessons learned through the development of policies (including those related to public health) during the pandemic. The pandemic has had devastating impacts on humanity that should not be understated, but it is also a warning that we need to redefine our relationship with nature and restore biodiversity. The considerations presented here will support the development of robust, evidence-based, and transformative policies for biodiversity conservation in a post-COVID-19 world.

Migration is a dynamic process, difficult to frame and even harder to predict.  Unlike other key events (most specifically death), migration follows uncertain pathways and reflects securities and insecurities that tend to play out across diverse social landscapes and include movers, non-movers as well as  households and communities.  Nevertheless, as the articles in this volume of Migration Letters reveal we continue to explore migration and its history; model decision-making and the challenges that movers face as they select new pathways; and explore as well as predict outcomes of remittance practices, policymaking and status. The articles in this issue and throughout our journal are often focused on what Tomas Faist (and others) call the crucial meso-level (Faist 1997).  This is the space where the decisions of individuals encounter and engage the household and other movers as well as non-movers, the community and the state.   The encounters and engagements that occur at the meso-level remind us that migration is not a simple decision, made by an independent actor. Rather, the decisions to move—whether as a migrant or refugee; whether across an international border or across a town—are complex and include many different voices, challenges and trials.

DEVELOPMENT OF A LIFE CYCLE ASSESSMENT (LCA) BASED DECISION-MAKING TOOL FOR THE ASSESSMENT OF BUILDING PRODUCTS

This paper introduces the need for the responsible selection of construction products and then analyses a number of assessment methodologies. Some computer packages and guidebooks that assist in life cycle assessment or aid construction product selection are briefly reviewed. Issues that affect decision-making and complexities in the construction industry are discussed. A tool for assisting responsible construction product selection is then presented that involves carrying out a streamlined life cycle assessment, comparing a novel product to a traditional product. The tool is pragmatic because only three environmental criteria are considered (resource consumption, energy use and human and ecological impacts) and a relative rather then absolute assessment is required. The decision-assisting methodology is demonstrated with a case study. The limitations and benefits of the streamlined LCA are finally presented.

The ecology of immigration discourse is an ideoscape in flux. It is a landscape constructed along human mobility, lifeworlds, ontological state security as well as along emotional and institutional complexities.  There has been significant recent proliferation of border literature and ethnographies that represent narratives of migrants on the U.S-Mexico border. Ethnography as non-fiction literature documents border trajectories.  This paper seeks to address how these trajectories are represented and or translated through a case study of the non-fiction work, The death and life of Aida Hernandez: a border story by Aaron Bobrow-Strain (2019) in which there is a distinct ecology in the ethos of ethnography and immigrant criminalization.  This case study assesses therefore the relation between the politics of ethnographic ideoscapes, translation and agency based upon Critical Discourse Analysis (Wodak & Kollner, 2008;  Wodak  & Meyer, 2016) as well as   evaluation and decision-making (Munday, 2012) when translating ethnography as a genre of represented  voices.
