Abstract

Wireless sensor networks are expected to be an integral part of any pervasive computing environment. This implies an ever‐increasing need for efficient energy and resource management of both the sensor nodes, as well as the overall sensor network, in order to meet the expected quality of data and service requirements. There have been numerous studies that have looked at the routing of data in sensor networks with the sole intention of reducing communication power consumption. However, there has been comparatively little prior art in the area of multi‐criteria based routing that exploit both the semantics of queries and the state of sensor nodes to improve network service longevity. In this paper, we look at routing in sensor networks from this perspective and propose an adaptive multi‐criteria routing protocol. Our algorithm offers automated reconfiguration of the routing tree as demanded by variations in the network state to meet application service requirements. Our experimental results show that our approach consistently outperforms, in terms of Network Lifetime and Coverage, the leading semantic‐based routing algorithm which reconfigures the routing tree at fixed periods.

Abstract

This chapter examines the fur trade commodity frontier in northeastern North America as a contested periphery, involving an evolving process of conflict and cooperation between North American indigenous groups and European powers. Native people used European powers for help in their battles with other native groups, and European colonial authorities attempted to use native people as proxies in their attempts to make up for often low European populations in the various North American colonies. Within the colonies there were also splits between commercial/trading interests and more purely geostrategic concerns. This chapter will explore these various conflicts involving the Iroquois, English and French, and will consider how the trade's fundamental material, environmental and geographical structure shaped the evolution of this peripheral extractive political economy and the efforts of those in the core seeking to exploit the area's resources.

Abstract

Purpose

This paper examines the relationship between a prime contractor's financial health and its mergers and acquisitions (M&A) spending in the defense industry. It aims to provide models that give the United States Department of Defense (DoD) indications of future M&A activity, informing decision-makers and contributing to ensuring competitive markets that benefit the consumer.

Design/methodology/approach

The study uses panel data regression models on 40 companies between 1985 and 2021. The company's financial health is assessed using industry-standard financial ratios (i.e. measures of profitability, efficiency, solvency and liquidity) while controlling for economic factors such as national productivity, defense budgets and firm size.

Findings

The results show a significant relationship between efficiency and M&A spending, indicating that companies with lower efficiency tend to spend more on M&As. However, there was no significant relationship between M&A spending and a company's profitability or solvency. These results were consistent with previous research and the study's hypotheses for profitability and solvency. However, the effect of liquidity was the opposite of the expected result, possibly due to the defense industry's different view on liquidity compared to previous research.

Originality/value

The paper provides insights into the relationship between a prime contractor's financial health and its M&A spending, a topic with limited research. The findings can inform policymakers and regulators on the industrial base's future M&A activity, ensuring competitive markets that benefit the consumer.

Abstract

Long-standing traditions of long-distance collaboration and networking make scholars a good test case for differentiating hype and reality in distributed, networked organizations. Our study of Canadian scholars in the GRAND research networks finds that they function more as connected individuals and less as members of a single bounded work group, often meeting their needs by tapping into diversified, loosely knit networks. Their internet use interpenetrates with in-person contact: the more they use one, the more they use the other. Despite digital networking, local proximity is important for collaboration and seniority for inter-team and interdisciplinary boundary spanning.

Abstract

Purpose

This study aims to examine several hypotheses, in conjunction with fundamental accounting concepts, to explain variations in the explanatory power of earnings for returns.

Design/methodology/approach

The authors explore three factors for their impact on the explanatory power of earnings. First, the accounting period preceding the earnings report is characterized by distinct intratemporal subperiod behavior. Recognizing this intratemporal nonstationarity is hypothesized to increase the explanatory power of earnings. Second, disaggregation of earnings into operating components is hypothesized to increase the explanatory power of earnings. Moreover, joint consideration of these first two factors is investigated. Third, the authors hypothesize that recognizing fundamental accounting concepts such as timeliness, predictive value, objectivity and verifiability offer key insights into the explanatory power of earnings.

Findings

The authors explore a sample of firms with management forecasts, which yields natural intratemporal subperiods – preforecast, forecast and realization periods – to generate hypotheses rooted in fundamental accounting concepts. The empirical evidence shows that recognition of nonstationary intratemporal behavior and earnings disaggregation yields a significant increase in the explanatory power of earning for returns. These findings are linked to fundamental concepts of accounting information.

Originality/value

This study is unique as it examines the joint role of nonstationarity and disaggregation in assessing the information conveyed in earnings. Importantly, results on these factors are linked to fundamental accounting concepts of timeliness, predictive value, objectivity and verifiability, along with their inherent trade-offs.

Abstract

Purpose – The purpose of this chapter is to trace the history of the cultural myth that children, especially boys, experience an abrupt heterosexual awakening during pubescence, from its origin during the 1950s to the present, with particular attention to a decrease in the age posited for such an awakening, from fourteen or fifteen to eight or nine or even earlier, until finally children are presented as heterosexually desiring from birth.

Methodology – The methodology is a content analysis of a sample of mass media texts starring or featuring prepubescent or pubescent boys, including films, television programs, comic books, comic strips, and juvenile novels, appearing in the United States between 1950 and 2007.

Findings – The rapid decrease in the age is correlated with an increased visibility of lesbian, gay, bisexual, and transgender (LGBT) adolescents, leading to the conclusion that it results from an attempt to privilege heterosexuality by making it appear a natural, inevitable outcome of biological maturation that is absent until puberty, whereas at the same time addressing homophobic insistence that no juvenile character be presented as gay by ensuring all characters, regardless of age, express heterosexual desire.

Research limitations/implications – The study is limited to a single causal factor, but it illustrates a complex cultural phenomenon, a shift in the way childhood is constructed, so there are doubtless other factors that should be explored. It is also necessary to explore why the change from presumed pubescent heterosexual awakening to presumed constitutional heterosexuality occurred at different rates depending on the race and social class of the character and the medium presented.

Abstract

Purpose

This paper examines how some specific psychological characteristics and stress levels of small and medium-sized enterprise (SME) key decision-makers (founders/managers) (KDMs) influence firm goal attainment based on two firm aspiration types.

Design/methodology/approach

This study hypothesizes that perceived resilience, social skills (self-promotion, ingratiation, expressiveness, social adaptability), and stress of SME KDMs will differently influence firm performance goal achievement based on firm historical versus social aspirations. IBM AMOS v27 is used to test these hypotheses on survey data of 267 Australian SME KDMs.

Findings

The study reveals that KDMs’ perceived resilience, social skills and stress differentially impact the achievement of firm performance goals when selecting firm-level historical and social aspirations. Resilience and some specific social skills can even have a detrimental effect on achieving firm goals when applying historical and social aspirations. Historical aspirations are based on the firm’s performance history, while social aspirations are based on the performance of a reference group of competitor firms. The differences in the relationship between these characteristics and the two aspiration types are also explained. Furthermore, the study reveals the important role of perceived stress levels in achieving firm performance goals, using both aspiration types.

Originality/value

This study is the first to investigate how the perceived use of some specific psychological characteristics of SME KDMs influence the ability to meet firm performance goals based on the discretionary use of historical and social aspirations and the relationship between these aspiration types. In this context, the paper explains the reasons for the differences and similarities in their use. Thus, this study provides an important empirical contribution to research on the emergent domain of micro-foundational SME goals.

Abstract

In this paper, we investigate the information content of non-current assets (NCA) among firms listed on the main board of Bursa Malaysia. Specifically, we investigate the information content of tangible and intangible NCA during the economic crisis period of 1997–1998. Our empirical analysis uses time-varying and fixed effects models for the period 1995–1999. We measure information content based on the association of analysts’ earnings forecasts errors (AFE) with both capitalized tangible and intangible NCA. We find evidence of higher information content in tangible NCA compared to intangible NCA during the Asian economic crisis period of 1997–1998. Our evidence is consistent with the assumption that tangible assets are more reliable compared to intangible assets for prediction of expected cash flows during economic crisis periods.
