    Inmate Education as a Service Learning Opportunity for Students: Preparation, Benefits, and Lessons Learned

    There is mounting evidence that prison inmates benefit from educational opportunities but may not be offered to them. In addition, when they are offered, priority is given to prisoners who will be released in the near future, and those serving long-term or life sentences are less likely to have access to classes. A service learning opportunity was created where students taught a life span development class to women serving long-term sentences. This article provides a guide to setting up the class while avoiding obstacles along the way. It also outlines benefits to students, inmates, supervising faculty, and society. In order to teach, students must apply what they have learned, and the prison experience challenges them to consider their power and privilege

    Time Optimal Control in Spin Systems

    In this paper, we study the design of pulse sequences for NMR spectroscopy as a problem of time optimal control of the unitary propagator. Radio frequency pulses are used in coherent spectroscopy to implement a unitary transfer of state. Pulse sequences that accomplish a desired transfer should be as short as possible in order to minimize the effects of relaxation and to optimize the sensitivity of the experiments. Here, we give an analytical characterization of such time optimal pulse sequences applicable to coherence transfer experiments in multiple-spin systems. We have adopted a general mathematical formulation, and present many of our results in this setting, mindful of the fact that new structures in optimal pulse design are constantly arising. Moreover, the general proofs are no more difficult than the specific problems of current interest. From a general control theory perspective, the problems we want to study have the following character. Suppose we are given a controllable right invariant system on a compact Lie group, what is the minimum time required to steer the system from some initial point to a specified final point? In NMR spectroscopy and quantum computing, this translates to, what is the minimum time required to produce a unitary propagator? We also give an analytical characterization of maximum achievable transfer in a given time for the two spin system.Comment: 20 Pages, 3 figure

    SERPINE2 Polymorphisms and Chronic Obstructive Pulmonary Disease

    A number of genome-wide linkage analyses have identified the 2q33.3-2q37.2 region as most likely to contain the genes that contribute to the susceptibility to chronic obstructive pulmonary disease (COPD). It was hypothesized that the SERPINE2 gene, which is one of the genes located at the 2q33.3-2q37.2 region, may act as a low-penetrance susceptibility gene for COPD. To test this hypothesis, the association of four SERPINE2 single nucleotide polymorphisms (SNPs; rs16865421A>G, rs7583463A>C, rs729631C>G, and rs6734100C>G) with the risk of COPD was investigated in a case-control study of 311 COPD patients and 386 controls. The SNP rs16865421 was associated with a significantly decreased risk of COPD in a dominant model for the polymorphic allele (adjusted odds ratio [OR]=0.66, 95% confidence interval [CI]=0.45-0.97, P=0.03). In haplotype analysis, the GACC haplotype carrying the polymorphic allele at the rs16865421 was associated with a significantly decreased risk of COPD when compared to the AACC haplotype (adjusted OR=0.58, 95% CI=0.38-0.89, P=0.01), and this effect was evident in younger individuals (adjusted OR=0.30, 95% CI=0.14-0.64, P=0.002). This study suggests that the SERPINE2 gene contributes to the susceptibility to COPD

    The genetics of chronic obstructive pulmonary disease

    Get PDF
    Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease caused by the interaction of genetic susceptibility and environmental influences. There is increasing evidence that genes link to disease pathogenesis and heterogeneity by causing variation in protease anti-protease systems, defence against oxidative stress and inflammation. The main methods of genomic research for complex disease traits are described, together with the genes implicated in COPD thus far, their roles in disease causation and the future for this area of investigation

    The Relationship between Environmental Efficiency and Manufacturing Firm's Growth

    Full text link
    This paper investigates the empirical link between emission intensity and economic growth, using a very large data set of 61,219 Italian manufacturing firms over the period 2000-2004. As a measure of lagged environmental performance (efficiency) at firm level we exploit NAMEA sector for CO2, NOx, SOx data over 1990-1999. The paper tests the extent to which (past) environmental efficiency/intensity, which is driven by structural features and firm strategic actions, including responses to policies, influences firms growth. Our results show, first, a typical trade off generally appearing for the three core environmental emissions we analyse: lower environmentally efficiency in the recent past allows higher degrees of freedom to firms and relax the constraints for growth, at least in this short/medium term scenario. Nevertheless, the size of the estimated coefficients is not large. Trade offs are significant for two emission indicators out of two, but quite negligible in terms of impacts, besides the case of CO2. For example, growth is reduced by far less than 0.1% in association to a 1% increase of environmental efficiency. In addition, non-linearity seems to characterise the economic growth-environmental performance relationship. Signals of inverted U shape appear: this may be a signal that both firm strategies and recent policy efforts are affecting the dynamic relationship between environmental efficiency and economic productivity, turning it from an usual trade off to a possible joint complementary/co-dynamics

    Perceived Impact Scale

    No full text
    The Perceived Impact Scale (Meyer et al., 2016) was developed to measure inmates\u27 self-reports of the impact that a life span human development class had on their level of knowledge, abilities, and other characteristics, such as self-awareness, emotional growth, and confidence. Following completion of the first class, a focus group was held with inmates who had completed the class to determine in what ways it had impacted them. There were no scales available in the literature to measure the array of constructs they identified as having changed so a scale was created. A sample of women serving long-term sentences provided two ratings on the last day of class, one for their recalled assessment of themselves on each construct before the course and one for their current assessment on each construct after the course. In addition, at the end of the scale, the women were asked to answer the item, Overall, how has this human developmental class affected your sense of purpose on a scale from 1 to 5. Psychometrics specific to this 37-item scale were not presented by the authors. (PsycTests Database Record (c) 2022 APA, all rights reserved
