    Not-so random acts of kindness : a guide to intentional kindness in the classroom

    Get PDF
    Much has been written about random acts of kindness – acts performed spontaneously and often to strangers. The topic of kindness and the benefits arising from performing kind acts holds both empirical and applied interest in the fields of education and psychology. Encouraging students to reflect upon and perform intentional acts of kindness develops perspective-taking, increased social membership, and a structured way of encouraging kindness within the school context. This paper provides an overview of kindness research and argues for the need to promote intentional acts of kindness by providing a framework for teachers to support students in the performance of intentional kindness.peer-reviewe

    Distributed Model Predictive Consensus via the Alternating Direction Method of Multipliers

    Full text link
    We propose a distributed optimization method for solving a distributed model predictive consensus problem. The goal is to design a distributed controller for a network of dynamical systems to optimize a coupled objective function while respecting state and input constraints. The distributed optimization method is an augmented Lagrangian method called the Alternating Direction Method of Multipliers (ADMM), which was introduced in the 1970s but has seen a recent resurgence in the context of dramatic increases in computing power and the development of widely available distributed computing platforms. The method is applied to position and velocity consensus in a network of double integrators. We find that a few tens of ADMM iterations yield closed-loop performance near what is achieved by solving the optimization problem centrally. Furthermore, the use of recent code generation techniques for solving local subproblems yields fast overall computation times.Comment: 7 pages, 5 figures, 50th Allerton Conference on Communication, Control, and Computing, Monticello, IL, USA, 201

    Is the GED an Effective Route to Postsecondary Education for School Dropouts?

    Get PDF
    We use data from the Texas Schools Microdata Panel (TSMP) to examine the extent to which dropouts use the GED as a route to post-secondary education. The paper develops a model pointing out the potential biases in estimating the effects of taking the “GED path” to postsecondary education. Lacking suitable instruments that would allow us to directly address potential biases, our approach is to base our estimates on a set of academically “at risk” students who are very similar in the 8th grade. We observe that the eventual high school graduates in this group have much better postsecondary education outcomes than do the similar at-risk 8th graders who dropped out and obtained a GED. Our model explains the observed differences, and allows for a discussion of the policy challenges inherent in improving the postsecondary outcomes of dropouts.GED, dropouts, post-secondary education

    Mass balances for a biological life support system simulation model

    Get PDF
    Design decisions to aid the development of future space based biological life support systems (BLSS) can be made with simulation models. The biochemistry stoichiometry was developed for: (1) protein, carbohydrate, fat, fiber, and lignin production in the edible and inedible parts of plants; (2) food consumption and production of organic solids in urine, feces, and wash water by the humans; and (3) operation of the waste processor. Flux values for all components are derived for a steady state system with wheat as the sole food source. The large scale dynamics of a materially closed (BLSS) computer model is described in a companion paper. An extension of this methodology can explore multifood systems and more complex biochemical dynamics while maintaining whole system closure as a focus

    Transpiration during life cycle in controlled wheat growth

    Get PDF
    A previously developed model of wheat growth, designed for convenient incorporation into system level models of advanced space life support systems is described. The model is applied to data from an experiment that grew wheat under controlled conditions and measured fresh biomass and cumulated transpiration as a function of time. The adequacy of modeling the transpiration as proportional to the inedible biomass and an age factor that varies during the life cycle are discussed

    How to allocate scarce health resources without discriminating against people with disabilities

    Get PDF
    One widely used method for allocating health care resources involves the use of cost-effectiveness analysis (CEA) to rank treatments in terms of quality-adjusted life-years (QALYs) gained. CEA has been criticized for discriminating against people with disabilities by valuing their lives less than those of non-disabled people. Avoiding discrimination seems to lead to the ’QALY trap’: we cannot value saving lives equally and still value raising quality of life. This paper reviews existing responses to the QALY trap and argues that all are problematic. Instead, we argue that adopting a moderate form of prioritarianism avoids the QALY trap and disability discrimination

    Measuring Self-Control

    Get PDF
    How significant are individual differences in self-control? Do these differences impact wealth accumulation? From where do they derive? Our survey-based measure of self-control provides insights into all three questions: 1.There are individual differences in self-control not only of a quantitative but also of a qualitative nature. In our sample, standard self-control problems of over-consumption are no more prevalent than are problems of under-consumption. 2.Standard self-control problems do impede wealth accumulation, particularly in liquid form. Problems of under-consumption have the opposite effects. 3.Self-control is linked to conscientiousness' much studied by psychologists. There is a related link with financial planning.
