Subject South Asia's EV outlook. Significance India and Pakistan have both set 30% electric mobility targets for 2030. While sales of passenger car electric vehicles (EVs) are very small, both countries already have substantial numbers of electric two- and three-wheeled vehicles, a transport phenomenon which has bypassed developed countries. South Asian countries lack EV component manufacturing capabilities. Impacts In-country assembly is a likely starting point to boost domestic EV production. Foreign partnerships should boost production capacity and facilitate technology transfer. Fast growth in electricity for transport demand will require electricity system adaptation, which South Asia is ill-equipped to deliver. India's plans to add 500 gigawatts of new renewable power to the electricity grid by 2030 would boost its EV scheme.

Electricity Bill

Smart buildings are a key element to walk towards smart cities and grids. Nonetheless, there are several degrees of intelligence. A first step is to incorporate commercial self-consumption solutions in buildings so they can manage the energy from local renewable power generators. A second step is to substitute this commercial solutions with an optimized Energy Management System (EMS) to reduce the electricity bill at the end of the month. Further. This EMS may contribute to stabilize and improve the quality and emissions of the electricity grid by offering some energy flexibility to the electricity system in favour of decentralization. This study compares the battery aging between buildings that count with an EMS to optimize the electricity bill under three scenarios in contrast to those that have a simple self-consumption kit. Lithium ion battery lifespan is estimated by means of an electric equivalent battery circuit model that runs on Matlab and simulates its behaviour through time. Moreover, this study evaluates the distribution of the battery costs regarding its use, observing that batteries controlled by simple self-consumption kits have longer lifespan because they are underused, ending up in higher calendar aging costs than the ones that are controlled by EMS.

ABSTRACT Engineering microbial hosts for the production of fungible fuels requires mitigation of limitations posed on the production capacity. One such limitation arises from the inherent toxicity of solvent-like biofuel compounds to production strains, such as Escherichia coli. Here we show the importance of host engineering for the production of short-chain alcohols by studying the overexpression of genes upregulated in response to exogenous isopentenol. Using systems biology data, we selected 40 genes that were upregulated following isopentenol exposure and subsequently overexpressed them in E. coli. Overexpression of several of these candidates improved tolerance to exogenously added isopentenol. Genes conferring isopentenol tolerance phenotypes belonged to diverse functional groups, such as oxidative stress response (soxS, fpr, and nrdH), general stress response (metR, yqhD, and gidB), heat shock-related response (ibpA), and transport (mdlB). To determine if these genes could also improve isopentenol production, we coexpressed the tolerance-enhancing genes individually with an isopentenol production pathway. Our data show that expression of 6 of the 8 candidates improved the production of isopentenol in E. coli, with the methionine biosynthesis regulator MetR improving the titer for isopentenol production by 55%. Additionally, expression of MdlB, an ABC transporter, facilitated a 12% improvement in isopentenol production. To our knowledge, MdlB is the first example of a transporter that can be used to improve production of a short-chain alcohol and provides a valuable new avenue for host engineering in biogasoline production. IMPORTANCE The use of microbial host platforms for the production of bulk commodities, such as chemicals and fuels, is now a focus of many biotechnology efforts. Many of these compounds are inherently toxic to the host microbe, which in turn places a limit on production despite efforts to optimize the bioconversion pathways. In order to achieve economically viable production levels, it is also necessary to engineer production strains with improved tolerance to these compounds. We demonstrate that microbial tolerance engineering using transcriptomics data can also identify targets that improve production. Our results include an exporter and a methionine biosynthesis regulator that improve isopentenol production, providing a starting point to further engineer the host for biogasoline production.

Subject India's new electric vehicle promotion plan. Significance India has implemented a new policy to support electromobility by 2030 based on a 1.4-billion-dollar incentive package primarily comprising subsidies for the purchase of electric vehicles (EVs). The policy targets low-cost electric mobility options such as two- and three-wheeled vehicles and public transport. This contrasts with the global focus on electrifying passenger cars, as rates of private vehicle ownership rise in developing countries. Impacts The success of the policy hinges on the scale of charging infrastructure or the facilitation of alternatives such as swappable batteries. Sales of internal combustion engine vehicles in the two-wheeler segment will face growing competition from EVs. India could leapfrog to shared electric mobility if the policy is successfully implemented.

The Impact

Purpose The purpose of this paper is to analyze the role of industrial self-supply in the transition process from centralized energy generation based on fossil fuels and nuclear power to decentralized supply based on renewable energies in the Bavarian electricity system. Design/methodology/approach To quantify effects on system and price stability, a model of the Bavarian electricity grid is created and used to simulate electricity system behavior during a 1-year period for scenarios that are characterized by parameter variations in industrial self-supply, nuclear power capacity, renewable power generation and the capacity of electricity imports. Findings The simulations show that industrial self-supply can reduce instances of maximum grid utilization by 23 per cent and, based on the merit-order effect, decrease electricity market prices by 1.90 and 5.03 €/MWh in the scenarios with and without nuclear power, respectively; these values represent 5.7 and 15.0 per cent of average market prices from 2014. Research limitations/implications The analysis shows that industrial self-supply can contribute to transforming the electricity system in a secure, sustainable and affordable manner. However, merit-order-based price effects have a limitation concerning the future applicability of results as quantified effects may not be permanent when the electricity system adapts. Originality/value This paper connects industrial self-supply and the merit-order effect within a nodal energy model. It provides insights into the relevant interdependencies and reciprocal effects by means of a simulation.

PurposeThe purpose of this paper is twofold. First, the authors aim to examine the role of talent management (TM) practices in talent migration from developed countries to Ghana that may enhance country’s economic development through knowledge transfer. The paper also investigates the determinants of migration to the African countries.Design/methodology/approachDiscussing the importance of self-initiated expatriates (SIEs), and how TM practices may contribute to global migration, the authors develop a set of propositions and build a theoretical framework showing how firms from Ghana can push SIEs to a longer stay in Ghana stimulating inward migration by implementing TM practices.FindingsThe authors claim that in the Ghanaian context expatriates may become migrants by overcoming negative perceptions about Ghana as a destination. Besides the authors argue that talent attraction and talent retention practices with governmental support, play an important role in inward migration to Ghana.Research limitations/implicationsNew agenda for talent managers in Africa, namely addressing the possibilities for expatriates’ retention by developing and implementing TM practices to ensure knowledge transferring from developed countries is suggested.Originality/valueThe theoretical framework provides a useful starting point for explaining the interconnections of TM and the conversion from expatriation to the global migration phenomena by African countries that broaden the TM scope beyond individual and organizational aspects. The authors state that TM systems take on the principal role of addressing talent migration especially in the African context and are capable of converting expatriates, specifically SIEs, into migrants to solve important tasks related to knowledge attraction to developing countries.

Financing Behavior

Purpose Recent papers on target capital structure show that debt ratio seems to vary widely in space and time, implying that the functional specifications of target debt ratios are of little empirical use. Further, target behavior cannot be adjudged correctly using debt ratios, as they could revert due to mechanical reasons. The purpose of this paper is to develop an alternative testing strategy to test the target capital structure. Design/methodology/approach The authors make use of a major “shock” to the debt ratios as an event and think of a subsequent reversion as a movement toward a mean or target debt ratio. By doing this, the authors no longer need to identify target debt ratios as a function of firm-specific variables or any other rigid functional form. Findings Similar to the broad empirical evidence in developed economies, there is no perceptible and systematic mean reversion by Indian firms. However, unlike developed countries, proportionate usage of debt to finance firms’ marginal financing deficits is extensive; equity is used rather sparingly. Research limitations/implications The trade-off theory could be convincingly refuted at least for the emerging market of India. The paper here stimulated further research on finding reasons for specific financing behavior of emerging market firms. Practical implications The results show that the firms’ financing choices are not only depending on their own firm’s specific variables but also on the financial markets in which they operate. Originality/value This study attempts to assess mean reversion in debt ratios in a unique but reassuring manner. The results are confirmed by extensive calibration of the testing strategy using simulated data sets.

The Impact

The impact of globalization on multinational enterprises was examined from the years 1980 to 2020. A scoping literature review was conducted for a total of 141 articles. Qualitative, quantitative, and mixed typologies were categorized and conclusions were drawn regarding the influence and performance (i.e., positive or negative effects) of globalization. Developed countries show more saturated markets than developing countries that favor developing country multinational enterprises to rely heavily on foreign sales for revenue growth. Developed country multinationals are likely to use more advanced factors of production to create revenue, whereas developing country multinationals are more likely to use less advanced forms. A number of common trends and issues showed corporate social responsibility, emerging markets, political issues, and economic matters as key to global market production. Recommendations signal a strong need for more research that addresses contributive effects in the different economies, starting with the emerging to the developed. Limitations of data availability and inconsistency posed a challenge for this review, yet the use of operationalization, techniques, and analyses from the business literature enabled this study to be an excellent starting point for additional work in the field.

Purpose – The purpose of this paper is to examine the significance of social isolation and the factors that create social isolation for residents of inner-city high-rise apartment communities. We critically examine how the physical environment and perceptions of safety in apartment buildings and the inner-city implicate the quality of interactions between residents and with their neighbourhood community. Design/methodology/approach – The authors used mixed-methods consisting of survey questionnaires supplemented by semi-structured interviews and focus group discussions using stratified random sampling to access predetermined key strata of inner-city high-rise resident population. Using coefficient of correlation we examine the significance of the association between social isolation, age and ethnicity amongst Auckland's inner-city high-rise residents. Findings – The authors found the experience and expression of social isolation consistent across all age groups, with highest correlation between functional social isolation and “being student”, and older adults (60+ years), length of tenure in current apartment and length of time residents have lived in the inner-city. Research limitations/implications – As a case study, we did not seek in this research to compare the experience and expressions of social isolation in different inner-city contexts, nor of inner-city high-rise residents in New Zealand and other countries, although these will be useful areas to explore in future studies. Practical implications – This study is a useful starting point to build evidence base for professionals working in health and social care services to develop interventions that will help reduce functional social isolation amongst young adults and older adults in inner-city high-rise apartments. This is particularly important as the inner-city population of older adults grow due to international migration, and sub-national shifts from suburbs to the inner-cities in response to governmental policies of urban consolidation. Originality/value – By identifying two forms of social isolation, namely functional and structural social isolation, we have extended previous analysis of social isolation and found that “living alone” or structural social isolation did not necessarily lead to functional social isolation. It also touched on the links between functional social isolation and self-efficacy of older adults, particularly those from immigrant backgrounds.

Purpose The purpose of this paper is to identify and prioritise social responsible mechanisms in apparel supply chains to extend social responsibility from large retailers in developed countries to producers in developing nations. Design/methodology/approach A framework that consists of supplier qualification and supplier relational mechanisms as two socially responsible mechanisms, with five factors and 18 dimensions is proposed. To prioritise the dimensions, analytic hierarchy process is employed by using a case study methodology of a major Australian retailer sourcing from Bangladesh manufacturers. Findings Results indicate that at the mechanism level, both retailer and manufacturers perceive qualification of manufacturer as by far the most critical element compared to the relational mechanism. However, substantial differences exist at the factor level; namely, that the social factor is critical for the retailer, whereas the economic factor is critical for the manufacturer. Within the relational mechanism, evaluation helps retailers to enforce social responsibility, while manufacturers believe collaboration helps. Research limitations/implications The major limitation of this study is the generalisation of the findings. The results obtained by focusing on a particular context in the Australian retail sector importing from Bangladesh, may not be applicable to other nations. Practical implications By highlighting the difference of opinion, this study assists managers in developing guidelines to better understand the socially responsible mechanisms in the retailer-manufacturer dyadic relationship and to propose strategies to address the differences. Originality/value This study advances the literature on inter-organisational relationship to retailer-manufacturer dyad for the implementation of social responsibility by including supplier qualification along with supplier relational mechanism.

Purpose This paper aims to answer the question of how the Polish representatives of social communication and media sciences communicate the most recent scientific findings in the media space, i.e. what types of publications are shared, what activities do they exemplify (sharing information about their own publications, leading discussions, formulating opinions), what is the form of the scientific communication created by them (publication of reference lists' descriptions, full papers, preprints and post prints) and what is the audience reception (number of downloads, displays, comments). Design/methodology/approach The authors present the results of analysis conducted on the presence of the most recent (2017–2019) publications by the Polish representatives of the widely understood social communication and media sciences in three selected social networking services for scientists: ResearchGate, Google Scholar and Academia.edu. The analyses covered 100 selected representatives of the scientific environment (selected in interval sampling), assigned, according to the OECD classification “Field of Science”, in the “Ludzie nauki” (Men of Science) database to the “media and communication” discipline. Findings The conducted analyses prove a low usage level of the potential of three analysed services for scientists by the Polish representatives of social communication and media sciences. Although 60% of them feature profiles in at least one of the services, the rest are not present there at all. From the total of 113 identified scientists' profiles, as little as 65 feature publications from 2017 to 2019. Small number of alternative metrics established in them, implies, in turn, that if these metrics were to play an important role in evaluation of the value and influence of scientific publications, then this evaluation for the researched Polish representatives of social communication and media sciences would be unfavourable. Originality/value The small presence of the Polish representatives of the communication and media sciences in three analysed services shows that these services may be – for the time being – only support the processes of managing own scientific output. Maybe this quite a pessimistic image of scientists' activities in the analysed services is conditioned by a simple lack of the need to be present in electronic channels of scientific communication or the lack of trust to the analysed services, which, in turn, should be linked to their shortcomings and flaws. However, unequivocal confirmation of these hypotheses might be brought by explorations covering a larger group of scientists, and complemented with survey studies. Thus, this research may constitute merely a starting point for further explorations, including elaboration of good practices with respect to usage of social media by scientists.
