Slavery in Massachusetts: Did Its Peculiar Nature Contribute to the Rise of Antislavery Advocates before 1776?

The purpose of this paper was to discover whether slavery in Massachusetts was distinct from that institution in the South. Slavery in this colony was an admixture of servitude and bondage due to several factors. Massachusetts physical environment, climate, and township system precluded the implementation of plantation type slavery. Secondly, Puritan ideas about the family and education resulted in slaves living with and becoming a part of the families they served, as well as receiving a rudimentary education in religious, academic, and occupational fields. Lastly, slaves in Massachusetts, unlike those in the South, had access to the same courts as whites, a fact that eventually led to their freedom in 1780. Thus, slavery was a unique and “peculiar” institution in Massachusetts

Triumph of an Idea_Japanese Internment and the Survival of Democracy

The principles found in the Declaration of Independence have been what has united the disparate cultures and ethnicities that make up the United States of America. Racial prejudice, war hysteria, and political opportunism have attempted at times to smother these principles. Such a time occurred during World War II when the Japanese Americans were interned. But, those in the academic community, the church communities, and the Nisei themselves ensured that the democratic principles of the Declaration would ultimately triumph

Control of a flexible beam using fuzzy logic

The goal of this project, funded under the NASA Summer Faculty Fellowship program, was to evaluate control methods utilizing fuzzy logic for applicability to control of flexible structures. This was done by applying these methods to control of the Control Structures Interaction Suitcase Demonstrator developed at Marshall Space Flight Center. The CSI Suitcase Demonstrator is a flexible beam, mounted at one end with springs and bearing, and with a single actuator capable of rotating the beam about a pin at the fixed end. The control objective is to return the tip of the free end to a zero error position (from a nonzero initial condition). It is neither completely controllable nor completely observable. Fuzzy logic control was demonstrated to successfully control the system and to exhibit desirable robustness properties compared to conventional control

Neural networks as a control methodology

While conventional computers must be programmed in a logical fashion by a person who thoroughly understands the task to be performed, the motivation behind neural networks is to develop machines which can train themselves to perform tasks, using available information about desired system behavior and learning from experience. There are three goals of this fellowship program: (1) to evaluate various neural net methods and generate computer software to implement those deemed most promising on a personal computer equipped with Matlab; (2) to evaluate methods currently in the professional literature for system control using neural nets to choose those most applicable to control of flexible structures; and (3) to apply the control strategies chosen in (2) to a computer simulation of a test article, the Control Structures Interaction Suitcase Demonstrator, which is a portable system consisting of a small flexible beam driven by a torque motor and mounted on springs tuned to the first flexible mode of the beam. Results of each are discussed

Adult missing persons:a concept analysis

Missing persons incidents incur considerable societal costs but research has overwhelmingly concentrated on missing children. Understanding the phenomenon among adults is underdeveloped as a result. We conducted an evolutionary concept analysis of the ‘missing person’ in relation to adults. Evolutionary concept analysis provides a structured narrative review methodology which aims to clarify how poorly defined phenomena have been discussed in the professional/academic literature in order to promote conceptual clarity and provide building blocks for future theoretical development. A systematic literature search identified k = 73 relevant papers from which surrogate terms for, and antecedents, consequences, and attributes of the occurrence of adult missing persons were extracted and analysed. The core attributes of the adult missing person are (i) actual or perceived unexpected or unwanted absence accompanied by an absence of information and (ii) a potential adverse risk outcome as perceived by those left behind. The centrality of mental ill-health in actual adult missing persons cases is not reflected in theoretical development which largely comprises descriptive typologies of variable quality and questionable utility. There is a clear need to shift research emphasis towards clinical and psychological domains of inquiry in order to further advance the field of adult missing persons research

Employment status and income as potential mediators of educational inequalities in population mental health

We assessed whether educational inequalities in mental health may be mediated by employment status and household income. Poor mental health was assessed using General Health Questionnaire ‘caseness’ in working age adult participants (N = 48 654) of the Health Survey for England (2001–10). Relative indices of inequality by education level were calculated. Substantial inequalities were apparent, with adjustment for employment status and household income markedly reducing their magnitude. Educational inequalities in mental health were attenuated by employment status. Policy responses to economic recession (such as active labour market interventions) might reduce mental health inequalities but longitudinal research is needed to exclude reverse causation

Trends in population mental health before and after the 2008 recession: a repeat cross-sectional analysis of the 1991-2010 health surveys of England

<p>Objective: To assess short-term differences in population mental health before and after the 2008 recession and explore how and why these changes differ by gender, age and socio-economic position.</p> <p>Design: Repeat cross-sectional analysis of survey data.</p> <p>Setting: England.</p> <p>Participants: Representative samples of the working age (25–64 years) general population participating in the Health Survey for England between 1991 and 2010 inclusive.</p> <p>Main outcome measures: Prevalence of poor mental health (caseness) as measured by the general health questionnaire-12 (GHQ).</p> <p>Results: Age–sex standardised prevalence of GHQ caseness increased from 13.7% (95% CI 12.9% to 14.5%) in 2008 to 16.4% (95% CI 14.9% to 17.9%) in 2009 and 15.5% (95% CI 14.4% to 16.7%) in 2010. Women had a consistently greater prevalence since 1991 until the current recession. However, compared to 2008, men experienced an increase in age-adjusted caseness of 5.1% (95% CI 2.6% to 7.6%, p<0.001) in 2009 and 3% (95% CI 1.2% to 4.9%, p=0.001) in 2010, while no statistically significant changes were seen in women. Adjustment for differences in employment status and education level did not account for the observed increase in men nor did they explain the differential gender patterning. Over the last decade, socio-economic inequalities showed a tendency to increase but no clear evidence for an increase in inequalities associated with the recession was found. Similarly, no evidence was found for a differential effect between age groups.</p> <p>Conclusions: Population mental health in men has deteriorated within 2 years of the onset of the current recession. These changes, and their patterning by gender, could not be accounted for by differences in employment status. Further work is needed to monitor recessionary impacts on health inequalities in response to ongoing labour market and social policy changes.</p&gt

The Peter Principle: An Experiment

The Peter Principle states that, after a promotion, the observed output of promoted employees tends to fall. Lazear (2004) models this principle as resulting from a regression to the mean of the transitory component of ability. Our experiment reproduces this model in the laboratory by means of various treatments in which we alter the variance of the transitory ability. We also compare the efficiency of an exogenous promotion standard with a treatment where subjects self-select their task. Our evidence confirms the Peter Principle when the variance of the transitory ability is large. In most cases, the efficiency of job allocation is higher when using a promotion rule than when employees are allowed to self-select their task. This is likely due to subjects’ bias regarding their transitory ability. Naïve thinking, more than optimism/pessimism bias, may explain why subjects do not distort their effort prior to promotion, contrary to Lazear’s (2004) prediction.
