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
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
Inmates Course Evaluation
The Inmates Course Evaluation (Meyer et al., 2016), was developed within the context of a study investigating an inmate educational course in a sample of female inmates serving long-term or life sentences. The measure assesses inmates\u27 evaluation of educational courses in prison covering the structure of the course, the content and workload, the overall quality of the instructors, and the contributions the course made to their learning. Inmates complete a short 3-item evaluation of each class meeting to provide feedback to the student instructors. The measure was revised after teaching the class one time because the prior scale was more applicable to a traditional college class. The final version consisted of 17-item on a Likert-type scale of 1 (agree) to 5 (disagree). No specific psychometric data were provided for the measure.
