Delineating where stability occurs in a contract provides the window of opportunity for procurement officials to positively affect cost and schedule outcomes. While the concept of a Cost Performance Index (CPI) "stability rule" has been routinely cited by Earned Value Management (EVM) authors since the early 1990's, more recent research questions the veracity of this stability rule. This paper resolves the controversy by demonstrating that the definition of stability matters. We find a morphing of the stability definition over time, with three separate definitions permeating the literature. Next, an analysis of Department of Defense contracts for both cost and schedule stability properties finds that the veracity of the stability rule is intricately tied to the definition used.

In pharmaceutical marketing, salespeople require promotional instruments to satisfy and retain their customers (physicians), but companies ignore the need because of the costs involved. It appears that the importance of promotional support is understood differently by managers and sales representatives. This study aims at developing a new construct called “promotional support”, as a resource support provided to salespeople to help them satisfy customer needs and achieve sales goals.

A detailed review of literature is followed by in-depth interviews to create items for the construct “promotional support”. Substantive validity is performed for identification of items measuring the construct. To initially validate the measures, a vignette study is performed. Formative index development procedure is followed. Data from a sample of 124 pharmaceutical sales representatives are collected and analyzed.

A formative construct is developed which possesses convergent (redundancy analysis) and nomological validity. The results of post hoc validation tests like confirmatory tetrad analysis and inter-item correlation are satisfactory and confirm the authors’ conceptualization.

The scale requires external validation by testing it with different samples such as managers of pharmaceutical firms.

This study will help managers of pharmaceutical firms gain insights into the role and importance of promotional inputs given to their sales representatives.

This study uses the formative scale development procedure to develop promotional support. This construct can be used to understand the effect of promotional support given to pharmaceutical sales representatives on other constructs, which in turn helps in theory-building.

Earned Value Management (EVM) is a project monitoring and control technique that enables the forecasting of a project's duration. Many EVM metrics and project duration forecasting methods have been proposed. However, very few studies have compared their accuracy and stability.

This paper presents an exhaustive stability and accuracy analysis of 27 deterministic EVM project duration forecasting methods. Stability is measured via Pearson's, Spearman's and Kendall's correlation coefficients while accuracy is measured by Mean Squared and Mean Absolute Percentage Errors. These parameters are determined at ten percentile intervals to track a given project's progress across 4,100 artificial project networks with varied topologies.

Findings support that stability and accuracy are inversely correlated for most forecasting methods, and also suggest that both significantly worsen as project networks become increasingly parallel. However, the AT + PD-ESmin forecasting method stands out as being the most accurate and reliable.

Implications of this study will allow construction project managers to resort to the simplest, most accurate and most stable EVM metrics when forecasting project duration. They will also be able to anticipate how the project topology (i.e., the network of activity predecessors) and the stage of project progress can condition their accuracy and stability.

Unlike previous research comparing EVM forecasting methods, this one includes all deterministic methods (classical and recent alike) and measures their performance in accordance with several parameters. Activity durations and costs are also modelled akin to those of construction projects.

Responsibility for human resource management is being spread around organizations in two ways: by decentralization, the allocation of personnel tasks formerly undertaken centrally to more local parts of the organization; and by devolution, the allocation of rules formerly undertaken by personnel specialists to line managers. Evidence from The Netherlands indicates that both processes are working there but with a considerable degree of doubt as to whether line managers can handle devolved personnel tasks. Comparative data from across Europe show that The Netherlands is in the top half of countries devolving these functions. Such decentralization and devolvement may mean a new role for personnel specialists.

The critical budgetting month of March is over, and we are at liberty to glance at the general position of libraries in regard to finance. As we anticipated, certain retrenchments have been effected in the form of reduced contributions from municipal rates, but while these have been regrettable they have in no case been so drastic as utterly to cripple the libraries involved. The unfortunate circumstance in the matter is the haphazard way in which reductions are made. An example worth quoting of this kind occurred at Ealing, where a councillor moved successfully that the appropriation for libraries be reduced to £1,500, without specifying in what directions economies were to be effected, or troubling himself about the working of a system of libraries upon this manifestly inadequate sum; but, after all, to tilt at haphazard methods is to tilt at British character. Naturally, the old exploded arguments against public libraries were advanced in various discussions, as at Croydon, where a councillor stated that the librarian's hours were spent “in handing novels to servant girls, who had nothing better to do,” a statement which he must have known to be untrue; but such arguments have met with small success, and on the whole the libraries have been supported.

In the realm of tourism and sustainability, transportation and mobility hold a crucial position. Among the green product categories, three-wheeled electric vehicles have gained significant attention due to their environmental benefits. However, research on consumers’ intentions to purchase these vehicles is limited, particularly in Asian destinations like Sri Lanka. This study aims to bridge this gap by examining the direct and indirect impacts of green brand awareness, green brand associations and green perceived quality of local Sri Lankans’ intention to choose branded electric three-wheelers in future purchase decisions.

A questionnaire survey garnered 400 usable responses, and structural equation modeling was used to test hypotheses.

The results indicate that green brand awareness, green brand associations and green perceived quality have a direct positive and significant effect on consumers’ intention to choose branded electric three-wheelers in future purchase decisions and green trust. Also, green trust has a positive and significant direct effect on consumers’ intention to choose branded electric three-wheelers in future purchase decisions. Furthermore, the results indicate that only green brand associations and green perceived quality have an indirect positive and significant effect on consumers’ intention to choose branded electric three-wheelers in future purchase decisions through green trust.

This research contributes to the tourism industry and other sectors involved in sustainability efforts in several ways. First, it emphasizes the importance of fostering positive associations with eco-friendly attributes and perceived product quality to build consumer trust and influence their purchase intentions for green products. Second, the study underscores the relevance of highlighting eco-friendly product attributes to stimulate consumer interest and adoption of green products. Finally, it theoretically underscores the significance of building trust through transparent and credible sustainability initiatives.

In this chapter, I utilize insights from symbolic interaction to analyze the identity work processes of larp subculture participants to construct and perform their in-game identities. I extend the research on larp subcultures in two ways. First, I place larping within the larger context of leisure subcultures and society by arguing that larping is representative of changes in leisure and subcultures in postmodern society. Second, I draw upon ethnographic data collected among the New England Role-playing Organization (NERO) to analyze larpers character identity performances. RPG and Larp researchers have developed several theories about the relationship between larp participants and their character performances. While these concepts provide a helpful framework for understanding the participant-character relationship, they undertheorize the in-game constructed performance of identity. Using symbolic interaction theory, I analyze the identity work processes larpers use to construct and perform their larp identities extending our understanding of the similarities between everyday identity and larpers' character identity performances.

This study aimed to find possible answers to whether U.S. universities are merely looking good or doing good regarding their third mission using elements of the triple bottom line (people, planet, prosperity) and the 2030 Agenda.

Qualitative exploratory empirical study based on an in-depth analysis of publicly available documents (i.e. mission statements and strategic planning) and information from the Impact Rankings 2020 edition (webpages). The study uses a multilevel analysis to capture the parameters “looking good” and “doing good.” The sample consists of 15 U.S. universities.

The findings demonstrate that universities are looking good in terms of their effort to support their third mission. Data show that all universities covered themes related to people and prosperity in their mission statements and strategic planning. However, when the authors dived into the managerial metrics, KPIs, benchmarks and other evidence to characterize them as doing good, the authors encountered some challenges in identifying evidence. The data suggest that universities most likely participated in the Impact Ranking act as “cherry pickers” and might participate in unproblematic goals for their organization.

The 3Ps and the 17 Sustainable Development Goals used in this study to examine the university public mission never used in other studies. The goal in this study was not to evaluate those universities in terms of looking good and doing good but rather to contribute to the gap in the literature and provide suggestions to university C-suite.

The purpose of this empirical study is to consider the interaction of self-service technologies (SSTs) with retail customers, exploring how retail customers perceive SST value and how this value affects their choice confidence when shopping.

We carried out a large shopper survey in collaboration with six French mass retailers. Digital kiosks and interactive tablets were the focal SSTs. Partial least squares-path modelling (PLS-PM) was used to test our cost‒benefit conceptual framework and the corresponding research hypotheses. Furthermore, through multigroup comparison analysis, we tested the moderating effect of customers’ subjective knowledge of the product category.

Functional and interactive benefits/costs arising from SST usage determine customer perceived value. The key notion of perceived SST value implies that people make favourable cost‒benefit tradeoffs. Customer choice confidence is positively affected by perceived SST value. Customer product category knowledge plays a key role as a moderator of human–SST interactions in phygital retail settings.

This paper is concerned with the role of SST in creating phygital experiences and delivering value to retail customers. This is a first attempt at examining how perceived SST value affects customer choice confidence and what role customer product category knowledge plays.
