Abstract

Purpose

The purpose of this paper is to demonstrate that using advanced powertrain technologies can help outperform the state of the art in F1 and LeMans motor racing. By a careful choice and sizing of powertrain components coupled with an optimal energy management strategy, the conflicting requirements of high-performance and high-energy savings can be achieved.

Design/methodology/approach

Five main steps were performed. First, definition of requirements: basic performance requirements were defined based on research on the capabilities of Formula 1 race cars. Second, drive cycle generation: a drive cycle was created using these performance requirements as well as other necessary inputs such as the track layout of Circuit de la Sarthe, the drag coefficient, the tire specifications, and the mass of the vehicle. Third, selection of technology: the drive cycle was used to model the power requirements from the powertrain components of the series-hybrid topology. Fourth, lap time sensitivity analysis: the impact of certain design decisions on lap time was determined by the lap time sensitivity analysis. Fifth, modeling and optimization: the design involved building the optimal energy management strategy and comparing the performance of different powertrain component sizings.

Findings

Five different powertrain configurations were presented, and several tradeoffs between lap time and different parameters were discussed. The results showed that the fastest achievable lap time using the proposed configurations was 3 min 9 s. It was concluded that several car and component parameters have to be improved to decrease this lap time to the required 2 min 45 s, which is required to outperform F1 on LeMans.

Originality/value

This research shows the capabilities of advanced hybrid powertrain components and energy management strategies in motorsports, both in terms of performance and energy savings. The important factors affecting the performance of such a hybrid race car have been highlighted.

Abstract

Birding, the active seeking out and identification of birds, is a wide‐spread and fast growing avocation on this continent, and indeed throughout the world. Jon Rickert's A Guide to North American Bird Clubs lists 17 national/continental organizations for both professional ornithologists and amateur birders and 844 state, provincial, and local associations. In addition, there are those legions of “unorganized” bird watchers and occasional, inquisitive discoverers of backyard birds. Members of this diverse congregation of birders have at least one thing in common — the need for a reliable identification tool enabling them to correctly label the just‐seen, unfamiliar bird. A field guide is just such a tool.

Abstract

Suicide behaviour rates vary significantly between countries due to a range of cultural, behavioural and health‐related factors. Gender and age‐related factors also appear to be impor tant key determinants of vulnerability to suicide ideation and suicide completion. The homeless population is par ticularly at risk, due to multiple complex issues that relate to social exclusion, alcohol, drug, mental health and nutritional issues. Studying homeless people is problematic due to access, the transitory nature of their contact with statutary services, problems of self‐repor t and recall in people ‐ some of whom have mental health and cognitive issues. There is an increasing interest from practitioners and academic researchers in spiritual factors that appear to modulate the responses of an individual to the internal and external threats that underlie the motivation to end his or her life. Effective approaches to suicide prevention and crisis management require a good understanding of the interplay between this complex set of biological, psychological and social domains. These will be explored in the final section of this review. This paper, therefore, aims to provide a non‐systematic review of the existing literature published in academic journals and relvant ‘grey literature’ and focuses on themes in the literature that will hopefully inform both policy and practice.

The purpose of this paper is to determine the project completion time and cost under non-deterministic conditions using interval gray numbers (IGNs).

Abstract

Purpose

The purpose of this paper is to determine the project completion time and cost under non-deterministic conditions using interval gray numbers (IGNs).

Design/methodology/approach

The earned value management (EVM) method based on the IGN has been developed.

Findings

The EVM method based on the IGN has been verified by a numerical example that can be applied to construction projects.

Practical implications

The EVM method, based on the gray numbers, reduces the budget and time shortage risk. Also, using this method, the managers would not be restricted to provide very exact values in their progress reports in the non-deterministic conditions.

Originality/value

One notable and significant point in all projects during the execution process is to estimate the project completion time and cost. However, non-deterministic conditions for both planned and actual physical completion percentage of projects have not been considered for predicting the project completion time and cost in the literature. Therefore, the novelty of this paper is the prediction of project completion time and cost under non-deterministic conditions using IGN.

Abstract

Purpose

The paper's aim is to create a framework for national readiness and receptivity to e‐commerce at both the business to business (B2B) as well as business to consumer (B2C) levels.

Design/methodology/approach

Relevant literature on e‐readiness is discussed in light of research on corruption and national values. A model is formulated at the macro level in which e‐readiness is predicted to be related to national culture values and corruption. Analysis at the micro level rests on existing literature related to trust and web site usability.

Findings

At the macro level of analysis, levels of perceived corruption within a country, and overarching national values are identified as significant contributors to e‐readiness especially in the B2B realm. At a more micro level, it is proposed that individual expectations regarding ability to trust an online vendor, and the suitability of usability characteristics of web site design contribute to e‐readiness at the B2C level. Taken together, macro and macro factors jointly contribute to a nation's readiness and receptivity to e‐commerce.

Research limitations/implications

The empirical work presented is based on aggregate level data from only one point in time. Results only provide generalized trends that may not be representative of all firms in a country or still applicable in the present time.

Practical implications

Practitioners are challenged to think beyond technological readiness and address factors such as corruption, national culture, and web design before entering new markets.

Originality/value

This paper identifies aspects of e‐readiness beyond purely technical infrastructure and provides a fresh empirical model. This study uniquely considers both micro and macro level characteristics that contribute to e‐readiness.

Abstract

Since its publication in 1996, Affective Events Theory (AET) has come to be regarded as the seminal explanation for structure, causes and consequences of affective experiences at work. AET does not, however, elucidate why, how, and when objects and events in the workplace trigger moods and emotions which in turn influence cognitive and behavioral outcomes. Consequently, AET does not yet provide us with a theoretical basis upon which to predict the way in which contextual, cognitive, motivational, or individual factors might moderate the impact of workplace events on affective states and subsequent behavior. In this chapter, we outline the central tenets of AET, and review a model of the processes underlying AET, with a view to understanding individual differences in the manifestation and consequences of affect in the workplace.

Abstract

Purpose

In academics and industry, significant efforts have been made to lead planners and control teams in evaluating project performance and control. In this context, numerous control metrics have been devised and put into practice, often with little emphasis on analyzing their underlying concepts. To cover this gap, this research aims to identify and analyze a holistic list of control metrics and their functionalities in the construction industry.

Design/methodology/approach

A multi-step analytical approach was conducted to achieve the study’s objectives. First, a holistic list of control metrics and their functionalities in the construction industry was identified. Second, a quantitative analysis based on social network analysis (SNA) was implemented to discover the most important functionalities.

Findings

The results revealed that the most important control metrics' functionalities (CMF) could differ depending on the type of metrics (lagging and leading) and levels of control. However, in general, the most significant functionalities include managing project progress and performance, evaluating the look-ahead level’s performance, measuring the reliability and stability of workflow, measuring the make-ready process, constraint management and measuring the quality of construction flow.

Originality/value

This research will assist the project team in getting a comprehensive sensemaking of planning and control systems and their functionalities to plan and control different dynamic aspects of the project.

Abstract

Purpose

The purpose of this study is to quantitatively examine the impact of perceived supervisor support, person-job fit (PJF) and person-organization fit (POF) on the company’s value through job satisfaction (JS).

Design/methodology/approach

Data were collected from 220 respondents selected from different organizations in India using standard questionnaires. To estimate the hypothesized model fit indices, partial least square structural equation modeling were used.

Findings

Findings suggest that there is a significant relationship among supervisor support, PJF and POF with JS and perceives company value.

Research limitations/implications

Human resource (HR) professionals need to understand how they can help to increase the JS of employees before they decide on HR measures that would help improve the perceived contribution to company value.

Originality/value

Support from the superior induces a sense of value and worthiness to the employee, which, in turn, strengthens the relationship between the employees with his/her organization. Along with this PJF and POF are other significant factors for employee satisfaction. If the person likes the job or in other words if the prescribed job is suitable for the person, then the employee feels significant, which amplifies JS. The same is applicable for the POF. Consequently, the perceived contribution to company value increases.

Abstract

Purpose

The purpose of this paper is to discuss different attempts that have been made to bridge the digital divide in Bangladesh, with special focus on the Community Information Centers (CICs), which are playing a unique and innovative role in reducing the digital gap.

Design/methodology/approach

The paper is a case study and is based on a survey method for collecting information through telephone (outbound call center). Besides these, internet, personal visits (as a project member) and other secondary sources such as research reports, Grameenphone internal reports, articles are used.

Findings

This paper highlights the existing initiatives which are bridging the break to build digital Bangladesh and focuses on how CIC is bridging the divide.

Research limitations/implications

This study will usher a new era for its internal values and the findings can be used by the advisory committees. The outcome of this study may, however, empower policy makers to make a decision and it is suggested that discussion and further writings are needed to bridge the digital divide in Bangladesh.

Originality/value

This paper is one of the very few studies which focus on the prospects of Community Information Centers in Bangladesh, particularly breaking the digital discrimination between rural and urban areas.
