A Proposal for a Minor in Sustainability

It is nearly undeniable that humans are altering the earth and rapidly depleting natural resources, compromising the future of generations to come. Thus, the importance of sustainability and sustainable practices is becoming increasingly important and relevant. While the world is working to innovate and prioritize sustainability, it is important that the University of Richmond must do the same. This proposal is for the addition of a minor in sustainability added to the university’s available education opportunities. The minor will be a total of six classes; three core sustainability classes and three additional classes to effectively cover the three pillars of sustainability (environmental, social, and economic sustainability). The minor would be beneficial to the University of Richmond in that it requires minimal costs of only two additional faculty members and would provide unquestionable benefits. A minor in sustainability would improve the university’s AASHE STARS rating, allow the university to gain a competitive advantage among other institutions, and would allow the university to entice more prospective students and produce more competitive graduates that are global citizens. Furthermore, the university would be symbolizing that it understands the importance of sustainability by introducing this minor. Around the globe, businesses, communities, colleges, and individuals are taking the necessary steps to work towards a sustainable future. The University of Richmond, with the introduction of a sustainability minor, has the opportunity to help lead the way instead of falling behind

Usage of plant examples in secondary school biology classes

Botanists have expressed concern over the dwindling recognition and emphasis of plants that currently exists in the fields of education and research. To ascertain if these claims pertain to high schools in the State of New Jersey, a survey on the frequency of using plant examples for teaching 10 biological principles was randomly distributed to secondary school biology teachers. Results from 80 respondents showed that on average, plants are used as examples in teaching 66% of these biological principles. The primary rationale cited by teachers for low or non-usage of plants was that they preferred animals as teaching examples. Underlying factors that explain this lack of plant emphasis include course requirements of teacher certification, the current biology teaching trends in our classrooms, and the recognition and funding opportunities of plant science. Recommendations include requiring a botany course for all college students in biological teaching programs, involving botanical societies in educational collaborations, encouraging a greater awareness of research in plant science, and stressing the importance of plants in secondary biology classrooms

Affective modulation of cognitive control is determined by performance-contingency and mediated by ventromedial prefrontal and cingulate cortex

Cognitive control requires a fine balance between stability, the protection of an on-going task-set, and flexibility, the ability to update a task-set in line with changing contingencies. It is thought that emotional processing modulates this balance, but results have been equivocal regarding the direction of this modulation. Here, we tested the hypothesis that a crucial determinant of this modulation is whether affective stimuli represent performance-contingent or task-irrelevant signals. Combining functional magnetic resonance imaging with a conflict task-switching paradigm, we contrasted the effects of presenting negative- and positive-valence pictures on the stability/flexibility trade-off in humans, depending on whether picture presentation was contingent on behavioral performance. Both the behavioral and neural expressions of cognitive control were modulated by stimulus valence and performance contingency: in the performance-contingent condition, cognitive flexibility was enhanced following positive pictures, whereas in the nonperformance-contingent condition, positive stimuli promoted cognitive stability. The imaging data showed that, as anticipated, the stability/flexibility trade-off per se was reflected in differential recruitment of dorsolateral frontoparietal and striatal regions. In contrast, the affective modulation of stability/flexibility shifts was mirrored, unexpectedly, by neural responses in ventromedial prefrontal and posterior cingulate cortices, core nodes of the “default mode” network. Our results demonstrate that the affective modulation of cognitive control depends on the performance contingency of the affect-inducing stimuli, and they document medial default mode regions to mediate the flexibility-promoting effects of performance-contingent positive affect, thus extending recent work that recasts these regions as serving a key role in on-task control processes

The role of anterior cingulate cortex in the affective evaluation of conflict

An influential theory of anterior cingulate cortex (ACC) function argues that this brain region plays a crucial role in the affective evaluation of performance monitoring and control demands. Specifically, control-demanding processes such as response conflict are thought to be registered as aversive signals by ACC, which in turn triggers processing adjustments to support avoidance learning. In support of conflict being treated as an aversive event, recent behavioral studies demonstrated that incongruent (i.e., conflict inducing), relative to congruent, stimuli can speed up subsequent negative, relative to positive, affective picture processing. Here, we used fMRI to investigate directly whether ACC activity in response to negative versus positive pictures is modulated by preceding control demands, consisting of conflict and task-switching conditions. The results show that negative, relative to positive, pictures elicited higher ACC activation after congruent, relative to incongruent, trials, suggesting that ACC's response to negative (positive) pictures was indeed affectively primed by incongruent (congruent) trials. Interestingly, this pattern of results was observed on task repetitions but disappeared on task alternations. This study supports the proposal that conflict induces negative affect and is the first to show that this affective signal is reflected in ACC activation
