Why Do Leaders Matter? The Role of Expert Knowledge

Why do some leaders succeed while others fail? This question is important, but its complexity makes it hard to study systematically. We draw on a setting where there are well-defined objectives, small teams of workers, and exact measures of leaders’ characteristics and organizational performance. We show that a strong predictor of a leader’s success in year T is that person’s own level of attainment, in the underlying activity, in approximately year T-20. Our data come from 15,000 professional basketball games and reveal that former star players make the best coaches. This ‘expert knowledge’ effect is large

The law relating to common land in England having regard to the commons registration act 1965

This thesis is intended to examine the Commons Registration 1965 Act in its historical context. The first part consists of a brief account of the history of common land making reference to the emergence of identifiable common rights, the inclosure movement and the progress towards protection for common land which was made in the late nineteenth and early twentieth centuries. The second part includes an examination of the problems which seriously affected common land during the twentieth century and which led to the appointment of a Royal Commission in 1955. The problems are examined from the points of view of various parties who might have an interest in common land, that is, the owner, the commoner, a rambler and a conservationist. Finally, a factual account is given of the problems which emerged when proposals were made to build Cow Green reservoir in Teesdale; the site in question consisted in part of common land. The third part contains an examination of the recommendations made by the Royal Commission in their Report regarding a system of registration for common land and town or village greens and new proposals regarding its maintenance and management. The provisions of the Commons Registration Act 1965 and related statutory instruments are considered in part four, the section being divided into three parts containing details of its aims, the provisions themselves and its effects. Of particular interest is the section regarding the effects because some of these cannot have been intended and merit detailed consideration. A modest body of case law has emerged as a result of the effect of the provisions in the Commons Registration Act 1965 and the cases are examined and discussed in this section. Particular emphasis is placed upon the decisions in Central Electricity Generating Board v Clwyd County Council [1976] TAER 251 and Box Parish Council v Lacey [1979] TAER 113.The final part examines the events which have taken place since 1965 and considers the recommendations contained in an Inter Departmental Working Party Report supplied by the Department of the Environment. There is also a discussion regarding a consultation document circulated with the Working Party Report and the replies to that document from a small number of interested bodies. Finally, there are eight appendices which contain additional material supplementary to the text

Why Do Leaders Matter? The Role of Expert Knowledge

Why do some leaders succeed while others fail? This question is important, but its complexity makes it hard to study systematically. We examine an industry in which there are well-defined objectives, small teams, and exact measures of leaders’ characteristics. We show that a strong predictor of a leader’s success in year T is that person’s own level of attainment, in the underlying activity, in approximately year T-20. Our data come from 15,000 professional basketball games. The effect on team performance of the coach’s ‘expert knowledge’ is large and is discernible in the data within 12 months of his being hired.organizational performance, firms, leadership, fixed-effects, productivity

Boss competence and worker well-being

Nearly all workers have a supervisor or ‘boss’. Yet little is known about how bosses influence the quality of employees’ lives. This study is a cautious attempt to provide new formal evidence. First, it is shown that a boss’s technical competence is the single strongest predictor of a worker’s job satisfaction. Second, it is demonstrated in longitudinal data -- after controlling for fixed effects -- that even if a worker stays in the same job and workplace a rise in the competence of a supervisor is associated with an improvement in the worker’s well-being. Third, a variety of robustness checks, including tentative instrumental-variable results, are reported. These findings, which draw on US and British data, contribute to an emerging literature on the role of expert leaders in organizations. Finally, the paper discusses potential weaknesses of existing evidence and necessary future research

Loblolly Pine Growth Response to Mid-rotational Treatments in an Eastern Texas Plantation

The effects of mid-rotational treatments (herbicide, prescribed burn, combination of herbicide and burn, and fertilization) on growth of loblolly pine were evaluated. Five replicates were established in a split-plot experimental design with fertilizer treatments as the whole-plot factor and competition control treatments as the sub-plot factor. Growth response was measured (as change in diameter, total height, and volume) at 8 months and again 4 years after treatments were applied. Mid-rotational treatments failed to enhance diameter, height, and volume growth of loblolly pine. However, a small positive response of diameter growth to fertilization was detected. Height growth was not significantly affected by any treatment 8 months after application date, while it was slightly negatively affected by herbicide and the combination of herbicide and prescribed burning 4 years after application of treatments. In this study, no substantial positive growth response to mid-rotational treatments was detected. However, loblolly growth response may vary from site to site based on differences in soil type, soil condition, and competition level. In addition, associated factors such as seedling quality and planting method may greatly influence loblolly growth response to mid-rotational treatments

Changes in understory vegetation of a ponderosa pine forest in northern Arizona 30 years after a Wildfire

Wildland fires can cause shifts in understory species composition and production. Many studies have examined short-term changes in understory vegetation following a wildfire; however, very few long term studies are available. The objective of this study was to examine changes in understory (herb and shrub) species composition and production since the 1972 Rattle Burn wildfire on the Coconino National Forest near Flagstaff, Arizona. Understory species composition and production were originally sampled in 1972, 1974, and 1980 and were re-sampled during July and August of 2002 and 2003 on 30 plots in each of four sites: high severity burn, low severity burn, unburned site prescribed burned in 1977, and an unburned site. Repeated measures analysis was used to test for the effects of fire and time on species production. The effects of fire and time on species composition as well as species production were tested using Multi-Response Permutation Procedures (MRPP). A lingering effect of the Rattle Burn wildfire on the understory plant production and composition was revealed. Burned sites may have greater understory production as compared to unburned sites up to 30 years after a wildfire. However, species composition on burned sites is altered. A significant relationship between tree density and understory species composition and production was found for 1972, but no relationship was found for overstory parameters and understory species production and composition for 2003

Spatial Autocorrelation and Pseudoreplication in Fire Ecology

Fire ecologists face many challenges regarding the statistical analyses of their studies. Hurlbert (1984) brought the problem of pseudoreplication to the scientific community’s attention in the mid 1980’s. Now, there is a new issue in the form of spatial autocorrelation. Spatial autocorrelation, if present, violates the traditional statistical assumption of observational independence. What, if anything, can the fire ecology community do about this new problem? An understanding of spatial autocorrelation, and knowledge of available methods used to reduce the effect of spatial autocorrelation and pseudoreplication will greatly assist fire ecology researchers

Investigating the Extent to Which Patients Should Control Access to Patient Records for Research: A Deliberative Process Using Citizens� Juries

BackgroundThe secondary use of health data for research raises complex questions of privacy and governance. Such questions are ill-suited to opinion polling where citizens must choose quickly between multiple-choice answers based on little information.ObjectiveThe aim of this project was to extend knowledge about what control informed citizens would seek over the use of health records for research after participating in a deliberative process using citizens' juries.MethodsTwo 3-day citizens' juries, of 17 citizens each, were convened to reflect UK national demographics from 355 eligible applicants. Each jury addressed the mission "To what extent should patients control access to patient records for secondary use?" Jurors heard from and questioned 5 expert witnesses (chosen either to inform the jury, or to argue for and against the secondary use of data), interspersed with structured opportunities to deliberate among themselves, including discussion and role-play. Jurors voted on a series of questions associated with the jury mission, giving their rationale. Individual views were polled using questionnaires at the beginning and at end of the process.ResultsAt the end of the process, 33 out of 34 jurors voted in support of the secondary use of data for research, with 24 wanting individuals to be able to opt out, 6 favoring opt in, and 3 voting that all records should be available without any consent process. When considering who should get access to data, both juries had very similar rationales. Both thought that public benefit was a key justification for access. Jury 1 was more strongly supportive of sharing patient records for public benefit, whereas jury 2 was more cautious and sought to give patients more control. Many jurors changed their opinion about who should get access to health records: 17 people became more willing to support wider information sharing of health data for public benefit, whereas 2 moved toward more patient control over patient records.ConclusionsThe findings highlight that, when informed of both risks and opportunities associated with data sharing, citizens believe an individual's right to privacy should not prevent research that can benefit the general public. The juries also concluded that patients should be notified of any such scheme and have the right to opt out if they so choose. Many jurors changed their minds about this complex policy question when they became more informed. Many, but not all, jurors became less skeptical about health data sharing, as they became better informed of its benefits and risks

The Paradox of Declining Female Happiness †

B y many measures, the progress of women over recent decades has been extraordinary. The gender wage gap has partly closed. Educational attainment has risen and is now surpassing that of men. Women have gained an unprecedented level of control over fertility. Technological change, in the form of new domestic appliances, has freed women from domestic drudgery. In short, women's freedoms within both the family and market sphere have expanded. Francine D. Blau's (1998) assessment of objective measures of female well-being since 1970 finds that women made enormous gains. Labor force outcomes have improved absolutely, as women's real wages have risen for all but the least-educated women, and relatively, as women's wages relative to those of men have increased for women of all races and education levels. Concurrently, female labor force participation has risen to record levels both absolutely and relative to that of men (Blau and Lawrence M. Kahn 2007 ). In turn, better market outcomes for women have likely improved their bargaining position in the home by raising their opportunities outside of marriage
