Abstract

Purpose

Some of the major concerns since the implementation of smart meters (prepaid meters) in some parts of Ghana is how electricity consumers have benefited from data obtained from these meters by providing important statistics on electricity-saving advice; this is one of the key demand-side management methods for achieving load reduction in residential homes. Appliance shifting techniques have proved to be an effective demand response strategy in load reduction. The purpose of this paper is therefore to help consumers of electricity understand when and how they can shift some appliances from peak to off-peak and vice versa.

Design/methodology/approach

The research uses an analysis technique of Richardson et al. (2010). In their survey on time-of-use surveys to determine the usage of electricity in households as far as appliance shifting was concerned, this study allowed for the assessment of how the occupants’ daily activities in households affect residential electricity consumption. Fell et al. (2014) modeled an aggregate of electricity demand using different appliances (n) in the household. The data for the peak time used in this study were identified from 05:00 to 08:00 and 17:00 to 21:00 for testing the load shifting algorithms, and the off-peak times were pecked from 10:00 to 16:00 and 23:00. This study technique used load management considering real-time scheduling for peak levels in the selected homes. The household devices are modeled in terms of controlled parameters. Using this study’s time-triggered loads on refrigerators and air conditioning systems, the findings suggested that peak loads can be reduced to 45% as a means of maintaining the simultaneous quality of service. To minimize peak loads to around 35% or more, Chaiwongsa and Wongwises (2020) have indicated that room air conditioning and refrigerator loads are simpler to move compared to other household appliances such as cooking appliances. Yet in conclusion, this study made a strong case that a decrease in household peak demand for electricity is primarily contingent on improvements in human behavior.

Findings

This study has shown that appliance load shifting is a very good way of reducing electrical consumption in residential homes. The comparative performance shows a moderate reduction of 1% in load as was found in the work done by Laicaine (2014). The results, however, indicate that load shifting to a large extent can be achieved by consumer behavioral change. The main response to this study is to advise policymakers in Ghana to develop the appropriate demand response and consumer education towards the general reduction in electrical load in domestic households. The difficulty, however, is how to get the attention of consumer’s on how to start using appliances with less load at peak and also shift some appliances from off-peak times. By increasing consumer knowledge and participation in demand response, it is possible to achieve more efficiency and flexibility in load reduction. The findings were benchmarked with existing comparison studies but may benefit from the potential production of structured references. However, the findings show that load shifting can only be done by modifying consumer actions.

Research limitations/implications

It should be remembered that this study showed that the use of appliances shifting in residential homes results in load reduction benefits for customers, expressed as savings in electricity prices. The next step will be to build on this cost/benefit study to explain and measure how these reductions transform into net consumer gains for all Ghanaian households.

Practical/implications

Load shifting will include load controllers in the future, which would automatically handle electricity consumption from various appliances in the home. Based on the device and user needs, the controllers can prioritize loads and appliance usage. The algorithms that underpin automatic load controllers will include knowledge about the behaviors of groups of end users. The results on the time dependency of activities may theoretically inform the algorithms of automatic demand controllers.

Originality/value

This paper addresses an important need for the country in the midst of finding solutions to an unending energy crisis. This paper presents demand response to the Ghanaian electricity consumer as a means to help in the reduction of load in residential homes. This is a novel research as no one has at yet carried out any research in this direction in Ghana. This paper has some new information to offer in the field of demand in household electricity consumption.

Abstract

Purpose

The impact of stress on personal and work-related outcomes has been studied in the information systems (IS) literature across several professions. However, the cybersecurity profession has received little attention despite numerous reports suggesting stress is a leading cause of various adverse professional outcomes. Cybersecurity professionals work in a constantly changing adversarial threat landscape, are focused on enforcement rather than compliance, and are required to adhere to ever-changing industry mandates – a work environment that is stressful and has been likened to a war zone. Hence, this literature review aims to reveal gaps and trends in the current extant general workplace and IS-specific stress literature and illuminate potentially fruitful paths for future research focused on stress among cybersecurity professionals.

Design/methodology/approach

Using the systematic literature review process (Okoli and Schabram, 2010), the authors examined the current IS research that studies stress in organizations. A disciplinary corpus was generated from IS journals and conferences encompassing 30 years. The authors analyzed 293 articles from 21 journals and six conferences to retain 77 articles and four conference proceedings for literature review.

Findings

The findings reveal four key research opportunities. First, the demands experienced by cybersecurity professionals are distinct from the demands experienced by regular information technology (IT) professionals. Second, it is crucial to identify the appraisal process that cybersecurity professionals follow in assessing security demands. Third, there are many stress responses from cybersecurity professionals, not just negative responses. Fourth, future research should focus on stress-related outcomes such as employee productivity, job satisfaction, job turnover, etc., and not only security compliance among cybersecurity professionals.

Originality/value

This study is the first to provide a systematic synthesis of the IS stress literature to reveal gaps, trends and opportunities for future research focused on stress among cybersecurity professionals. The study presents several novel trends and research opportunities. It contends that the demands experienced by cybersecurity professionals are distinct from those experienced by regular IT professionals and scholars should seek to identify the key characteristics of these demands that influence their appraisal process. Also, there are many stress responses, not just negative responses, deserving increased attention and future research should focus on unexplored stress-related outcomes for cybersecurity professionals.

Abstract

Purpose

The purpose of this paper is to test the effects of citizens’ support for two rival and opposing conceptions of political involvement, political consumerism and stealth democracy, on their attitudes about demand response (flexible consumption) and prosumerism (self-production) in the context of making of Finnish energy policy. Stealth democracy represents an established view on the role of citizens in energy policy making: the energy sector has traditionally been presented as a technocratic domain reserved for experts and businessmen. By contrast, political consumerism can be seen as an expression of “energy democracy”.

Design/methodology/approach

The data is based on a postal survey and an internet survey that were conducted in 2016 among a random sample representing Finns who were between 18 and 75 years. The dependence of the support for demand response and prosumerism on the endorsement of political consumerism and stealth democracy will be tested statistically (Pearson chi-square).

Findings

The endorsement of demand response mainly depended statistically on citizens’ attitudes towards political consumerism and stealth democracy. However, comparing electricity prices and changing electricity suppliers did not depend on adherence to political consumerism and stealth democracy. Nevertheless, in these cases, support was higher among the supporters of political consumerism than among supporters of stealth democracy. By contrast, the endorsement of prosumerism, for instance, in terms of factors that influence citizens’ decisions to invest in electricity generation in their households, depended statistically on citizens’ attitudes on political consumerism and stealth democracy.

Research limitations/implications

It might be that the variables used in this study to measure stealth democracy are not specific enough. More generally, Finns’ willingness to support for stealth democracy may be based on or at least encouraged by the misunderstandings of democratic politics: more information is needed on the level of knowledge that citizens have about normative principles of democratic decision-making processes.

Practical implications

The implication of this study for energy policy making is that there are (at least in Finland) good preconditions for developing a decentralized energy system: citizens are ready to adopt a more active role as energy citizens in terms of demand response and prosumerism – irrespective of their attitudes on macro-level attitudes on governmental institutions. Democratization of the energy system could strengthen the legitimacy of energy policy making.

Social implications

Citizens’ attitudes indicate that their potential for involvement needs to be strengthened in the spirit of energy democracy: the idea of energy democracy needs to be seen in terms of the demand for increased accountability and democratization of the energy sector that was previously not seen as requiring public involvement and was most often depoliticized and dominated by technocrats. However, strengthening energy democracy through demand response and prosumerism is not without its problems: utilization of these devices requires a relatively large amount of resources which depend on the individuals’ socio-economic position. Thus, energy democracy cannot replace but complement electoral participation as a form of energy policy involvement.

Originality/value

The contribution of this study is to fill a part of the research gap linking to ongoing energy transitions. As a socio-technical transition can take place only if citizens support and participate in it, we need to better understand citizens’ attitudes on energy consumption and production and energy policy involvement. Citizens’ attitudes on energy production and consumption are becoming more and more critical for managing the energy sector as a result of that the share of wind power and solar power is increasing in the energy system. In a decentralized energy system, citizens have to be prepared to change their modes of operation. To the best of the authors’ knowledge, the originality of this study is to test the impact of citizens’ political attitudes on the endorsement of demand response and prosumerism.

Abstract

In this chapter, we review empirical research evidence on the relationship between stressors and catecholamines (i.e., adrenaline and noradrenaline) and cortisol. With respect to acute stressors, both laboratory and field research have shown that the exposure to stressors leads to an increase in catecholamine and cortisol levels. With respect to more chronic stressors, research evidence is less consistent. Chronic mental workload was found to be related to elevated adrenaline levels. With respect to cortisol responses the interaction between workload and other variables seems to play a role. Empirical studies suggest that chronic stressors affect the responsivity to acute stressors. Research showed that after the exposure to stressors catecholamine and cortisol recovery is delayed.

Abstract

Purpose

The purpose of this paper is to investigate the application of the dynamic vehicle routing problem for last mile distribution during disaster response. The authors explore a model that involves limited heterogeneous vehicles, multiple trips, locations with different accessibilities, uncertain demands, and anticipating new locations that are expected to build responsive last mile distribution systems.

Design/methodology/approach

The modified simulated annealing algorithm with variable neighborhood search for local search is used to solve the last mile distribution model based on the criterion of total travel time. A dynamic simulator that accommodates new requests from demand nodes and a sample average estimator was added to the framework to deal with the stochastic and dynamicity of the problem.

Findings

This study illustrates some practical complexities in last mile distribution during disaster response and shows the benefits of flexible vehicle routing by considering stochastic and dynamic situations.

Research limitations/implications

This study only focuses day-to-day distribution on road/land transportation for distribution, and additional transportation modes need to be considered further.

Practical implications

The proposed model offers operational insights for government disaster agencies by highlighting the dynamic model concept for supporting relief distribution decisions. The result suggests that different characteristics and complexities of affected areas might require different distribution strategies.

Originality/value

This study modifies the concept of the truck and trailer routing problem to model locations with different accessibilities while anticipating the information gap for demand size and locations. The results show the importance of flexible distribution systems during a disaster for minimizing the disaster risks.

Abstract

Purpose

This article aims to explore the fundamental negotiation structure as a demand/response dynamic. It tests it in a complex business system, where a manager as a negotiator is confronted with multiple demands or pressures at different levels from a variety of stakeholders, both external and internal.

Design/methodology/approach

Based on concrete examples from the automotive industry, it presents an analytical framework to tackle all negotiation interactions.

Findings

This article suggests that it is possible to describe all negotiation interactions, whether they are simple or complex, through a demand/response framework.

Originality/value

This contribution examines a fundamental structure for negotiation responsibility – the demand/response dynamic – defining the mission of any negotiator in deal-making or dispute resolution as to try to supply a response to the expressed crossed demands. Second, the proposed theoretical model of demand/response is transposed and tested in a managerial system where a sales negotiator is confronted with demands from more sources, both external and internal, with the responsibility to satisfy as best as possible the various stakeholders and the capacity to address each of them with different moves.
