MR. SERBY'S article on trimming and balance tabs gives a very concise theoretical explanation of the working of trimmer and balance tabs, and explains certain characteristics which have baffled most designers.

I PROPOSE to review the company history firstly by reference to some of the many types of aeroplanes and projects it has engaged upon. A major difficulty arises in that to date the aeroplane type numbers used within the company already exceed 140. Of necessity, therefore, the types mentioned must be strictly limited.

With this number the Library Review enters on its ninth year, and we send greetings to readers at home and abroad. Though the magazine was started just about the time when the depression struck the world, its success was immediate, and we are glad to say that its circulation has increased steadily every year. This is an eminently satisfactory claim to be able to make considering the times through which we have passed.

DEAR SIR,—I read with much interest Mr. J. H. Crowe's article on Longitudinal Stability, which was published in the March issue of AIRCRAFT ENGINEERING. It forms a useful summary of present‐day knowledge on the glider stability problem, but is rather misleading in the section devoted to the effects of slipstream.

Group incentive schemes have been shown to be positively associated with firm performance but it remains an open question whether this association can be explained by the motivating characteristics of the group-incentive scheme itself, or if this is due to factors that tend to accompany group-incentive schemes. We use a controlled experiment to directly test if group-incentive schemes can motivate sustained individual effort in the absence of rules, norms, and institutions that are known to mitigate free-riding behavior.

We use a controlled lab experiment that randomly assigns subjects to one of three compensation contracts used to incentivize an onerous effort task. Two of the compensation contracts are group-incentive schemes where subjects have an incentive to free-ride on the efforts of their coworkers, and the third (control) is a flat-wage contract.

We find that both group-incentive schemes resulted in sustained, higher performance relative to the flat-wage compensation contract. Further, we do not find evidence of free-riding behavior under the two group-incentive schemes.

Although we do find sustained cooperation/performance over the three work periods of our experiment under the group-incentive schemes, further testing would be required to evaluate whether group-incentive schemes can sustain cooperation over a longer time horizon without complementary norms, policies, or institutions that mitigate free-riding.

By unambiguously showing that group-incentive schemes can, by themselves, motivate workers to provide sustained levels of effort, this suggests that the “1/n problem” may be, in part, an artifact of the rational-actor modeling conventions.

This study investigates how organizations in Brazil address sustainability concerns through collaborative governance efforts with strategic stakeholders. Organizations from New Zealand were considered as benchmarks for comparison.

This study is based on a qualitative exploratory research, supported by semistructured interviews. Ten organizations are interviewed, five from each country. Thematic analysis is used to analyze the interview data. Central management practices adopted by organizations are presented, and the goals, benefits, and limitations associated with collaborative initiatives are investigated.

The findings reveal that organizations in Brazil and in New Zealand are employing similar management and sustainability practices. Companies in both countries observe that collaborative efforts with strategic stakeholders improve their ability to meet market demands and jointly develop innovative solutions toward sustainability goals while exchanging knowledge and enhancing their operational effectiveness. Organizations perceive a number of tangible and nontangible value creation outcomes from sustainability practices, such as brand and reputational gains, improved supply chain management, and risk management attainments. The results also present limitations, such as internal limitations of organizations concerning how their executives and general staff incorporate sustainability issues into their organizations’ strategic planning and operational decisions.

Market pressures toward greener and more responsible operations equally affected organizations in both countries, without differentiation in operation between an emerging country such as Brazil and a developed country such as New Zealand. Directions for future research are presented. These are based on how organizations measure sustainability outcomes of management practices and collaborative alliances, and how organizations map upcoming market demands and opportunities to deliver more value to society as the sustainable development debate continues to evolve.

The 2008–2009 financial crisis has renewed concerns about managerial short-termism and its negative effects. Based on intertemporal choice theory, this chapter aims to identify the role that performance measurement and compensation systems can play in orienting managers toward building long-term performance potential in addition to achieving short-term results.

The findings suggest that certain types of measures used – in particular broader, more inclusive financial indicators, risk-adjusted measures, and key nonfinancial value drivers – as well as the timing of measurement and payment of rewards can lead to reduced time discounting and a lower devaluation of the future, and consequently to a prioritized managerial attention focus on long-term company goals.

This chapter contributes to a better understanding of the institutional determinants of managerial long-term orientation and the influence of organizational systems on goal prioritization in managerial intertemporal choice processes.

The findings have practical relevance for the design of incentive systems that aim to place an emphasis on ensuring long-term value creation.

Systems that guide managerial behavior toward the long term can help to increase economic and societal sustainability.

Despite the emergence of more integrated performance measurement approaches, time horizon has not been in the main focus of research in the field yet. This review provides a first structured overview of the temporal effects of different elements of performance measurement and compensation systems.

The COVID-19 pandemic stressed the health care sector's longstanding pain points, including the poor quality of frontline work and the staffing challenges that result from it. This has renewed interest in technology-centered approaches to achieving not only the “Triple Aim” of reducing costs while raising access and quality but also the “Quadruple Aim” of doing so without further squeezing wages and abrading job quality for frontline workers.

How can we leverage technology toward the achievement of the Quadruple Aim? I view this as a “grand challenge” for health care managers and policymakers. Those looking for guidance will find that most analyses of the workforce impact of technological change consider broad classes of technology such as computers or robots outside of any particular industry context. Further, they typically predict changes in work or labor market outcomes will come about at some ill-defined point in the medium to long run. This decontextualization and detemporization proves markedly problematic in the health care sector: the nonmarket, institutional factors driving technology adoption and implementation loom especially large in frontline care delivery, and managers and policymakers understandably must consider a well-defined, near-term, i.e., 5–10-year, time horizon.

This study is predicated on interviews with hospital and home health agency administrators, union representatives, health care information technology (IT) experts and consultants, and technology developers. I detail the near-term drivers and anticipated workforce impact of technological changes in frontline care delivery. With my emergent prescriptions for managers and policymakers, I hope to guide sectoral actors in using technology to address the “grand challenge” inherent to achieving the Quadruple Aim.

THIS issue of AIRCRAFT ENGINEERING might without excess of exaggeration almost be described as a special number for inspectors and ground engineers—for, indeed, that elusive individual, to whom we have on occasion referred before, the “practical man.”
