Never Being Able to Say You’re Sorry: Barriers to Apology By Leaders in Group Conflicts

Conner and Jordan discuss three implications of the foregoing analysis for leaders, peacemakers, and scholars interested in apology as an instrument to advance justice, prevent destructive conflict, and promote cooperation. First, an effective apology is likely to occur only after other changes have softened up negative attitudes between the groups--referred to here as ripeness. Second, even with a degree of ripeness, apology is unlikely without a window of opportunity, a confluence of circumstances that permits the leader to limit the scope of the apology so as not to concede too much. Third, even if these conditions are satisfied, words alone are not enough for an apology to be effective

Shutdown reactivity worth of reactor control rods by a subcritical multiplication method

Two modified subcritical multiplication methods for measuring the reactivity worth of control elements were developed and investigated. The first involved the calibration of a subcritical count interval by the asymptotic period method. The second involved the calibration of a subcritical count interval by a rod interchange with the reactor regulating rod which had previously been calibrated by the asymptotic period method. The accuracy of these methods is relatively poor. this inaccuracy is due to shadowing effects and to the spatial harmonics which exist in the core. An investigation of the spatial harmonics to determine the best location for the neutron detector is needed --Abstract, page ii

Michigan Environmental Protection Act

Each of the questions discussed in this note revolve around the same basic issue: the propriety of vesting broad power in the courts to prevent environmental destruction, and to develop an environmental common law. The need for the broad standard of the Act derives from the complexity of the problem. The clear authority of the courts to decide cases which have been, or should have been dealt with by an administrative agency is important both for the relationship it establishes between citizens and agencies, and to insure that the policies of the Act will be implemented. In responding to these needs the legislature appears to have violated no constitutional barrier

Michigan\u27s Environmental Protection Act of 1970: A Progress Report

The Michigan Environmental Protection Act of 1970 (EPA) represents a departure from the long-standing tradition under which control of environmental quality has been left almost exclusively in the hands of regulatory agencies: it gives to ordinary citizens an opportunity to take the initiative in environmental law enforcement

Teaching Elementary Mathematics with Educational Robotics

Current education reforms call for engaging students in learning science, technology, engineering, and mathematics (STEM) in an integrative way. This critical case study of one fourth grade teacher investigated the use of educational robots (ER) not only for teaching coding, but as an instructional support in teaching mathematical concepts. To support teachers in teaching coding in an integrative and logical manner, our team developed the Collective Argumentation Learning and Coding (CALC) approach. The CALC approach consists of three elements: choice of task, coding content, and teacher support for argumentation. After a cohort of elementary teachers completed a professional development course, we followed them into their classrooms to support and document implementation of the CALC approach. Data for this case consisted of video recordings of two lessons, a Pre-interview, and Post-interview after each lesson. Research questions included: How does an elementary teacher use the CALC approach (integrative STEM approach) to teach mathematics concepts with ER? What are the teacher’s perspectives towards teaching mathematics with ER using an integrative STEM approach? Results from this critical case provide evidence that teachers can successfully integrate ER into the mathematics curriculum without losing coherence of mathematics topics and while remaining sensitive to students’ needs

Ecological genetics of an induced plant defense against herbivores: Additive genetic variance and costs of phenotypic plasticity.

Abstract. Adaptive phenotypic plasticity in chemical defense is thought to play a major role in plant-herbivore interactions. We investigated genetic variation for inducibility of defensive traits in wild radish plants and asked if the evolution of induction is constrained by costs of phenotypic plasticity. In a greenhouse experiment using paternal half-sibling families, we show additive genetic variation for plasticity in glucosinolate concentration. Genetic variation for glucosinolates was not detected in undamaged plants, but was significant following herbivory by a specialist herbivore, Pieris rapae. On average, damaged plants had 55% higher concentrations of glucosinolates compared to controls. In addition, we found significant narrow-sense heritabilities for leaf size, trichome number, flowering phenology, and lifetime fruit production. In a second experiment, we found evidence of genetic variation in induced plant resistance to P. rapae. Although overall there was little evidence for genetic correlations between the defensive and life-history traits we measured, we show that more plastic families had lower fitness than less plastic families in the absence of herbivory (i.e., evidence for genetic costs of plasticity). Thus, there is genetic variation for induction of defense in wild radish, and the evolution of inducibility may be constrained by costs of plasticity
