Identical Profiles, Different Paths: Addressing Self-selection Bias in Learning Community Cohorts

This article presents a method for addressing the self-selection bias of students who participate in learning communities (LCs). More specifically, this research utilizes equivalent comparison groups based on selected incoming characteristics of students, known as bootstraps, to account for self-selection bias. To address the differences in academic preparedness in the fall 2012 cohort, three stratified random samples of students were drawn from the non-LC population to match the LC cohort in mean ACT composite scores and mean high school percentile ranks. This process is called bootstrapping. The study suggests that LCs do impact student academic achievement and retention. The results indicate that LC students with similar entering characteristics to those of the bootstrap sample had higher rates for both GPA and retention than non-LC participants

The Rocky Road from Experience to Expression of Emotions - Women’s Anger about Sexism

We investigated women’s anger expression in response to sexism. In three studies (Ns = 103, 317, and 241), we tested the predictions that women express less anger about sexism than they experience—the anger gap—and that the anger expressed by women is associated with instrumental concerns, specifically perceived costs and benefits of confronting sexism. To estimate the specificity of the proposed gap, we compared women’s anger reactions to men’s anger reactions as well as anger reactions to sadness reactions. Across studies, we found support for the anger gap, that is, lower anger expression than experience, and the gap was more pronounced for women than for men (Study 3). Surprisingly, a gap also occurred in sadness reactions. Regarding instrumental concerns, there was converging evidence that expressed anger was negatively associated with individual costs. We also investigated whether anger expression can be encouraged through women’s identification with feminists (Studies 1 and 2) and support by other women (Study 2); yet, we found no evidence. We conclude that, to understand women’s—and men’s—reactions to sexism, it is critical not to mistake their emotion expression for how they really feel, but instead to also consider strategic concerns.

Marketing Learning Communities to Generation Z: The importance of face-to-face interaction in a digitally driven world

This article aims to identify the marketing strategies utilized by Learning Community (LC) administrators at two large, public, four-year research universities in the Midwest. The use of digital media coupled with face-to-face interaction is identified as an effective method of marketing LCs to the newest population of incoming college students, referred to as Generation Z. The students who fall into the Generation Z population are identified as technologically savvy and highly attuned to the variety of digital platforms available to share, gather, and exchange information. They expect to receive information through digital media. Findings on LC marketing success indicate that LC administrators should utilize current trends of conveying information through digital marketing strategies which serve to reinforce face-to-face interactions in order to recruit Generation Z students into LC programs

CEA systems: the means to achieve future food security and environmental sustainability?

As demand for food production continues to rise, it is clear that in order to meet the challenges of the future in terms of food security and environmental sustainability, radical changes are required throughout all levels of the global food system. Controlled Environment Agriculture (CEA) (a.k.a. indoor farming) has an advantage over conventional farming methods in that production processes can be largely separated from the natural environment, thus, production is less reliant on environmental conditions, and pollution can be better restricted and controlled. While output potential of conventional farming at a global scale is predicted to suffer due to the effects of climate change, technological advancements in this time will drastically improve both the economic and environmental performance of CEA systems. This article summarizes the current understanding and gaps in knowledge surrounding the environmental sustainability of CEA systems, and assesses whether these systems may allow for intensive and fully sustainable agriculture at a global scale. The energy requirements and subsequent carbon footprint of many systems is currently the greatest environmental hurdle to overcome. The lack of economically grown staple crops which make up the majority of calories consumed by humans is also a major limiting factor in the expansion of CEA systems to reduce the environmental impacts of food production at a global scale. This review introduces the concept of Integrated System CEA (ISCEA) in which multiple CEA systems can be deployed in an integrated localized fashion to increase efficiency and reduce environmental impacts of food production. We conclude that it is feasible that with sufficient green energy, that ISCEA systems could largely negate most forms of environmental damage associated with conventional farming at a global scale (e.g., GHGs, deforestation, nitrogen, phosphorus, pesticide use, etc.). However, while there is plenty of research being carried out into improving energy efficiency, renewable energy and crop diversification in CEA systems, the circular economy approach to waste is largely ignored. We recommend that industries begin to investigate how nutrient flows and efficiencies in systems can be better managed to improve the environmental performance of CEA systems of the future

Palladium-unleashed proteins: gentle aldehyde decaging for site-selective protein modification

Protein bioconjugation frequently makes use of aldehydes as reactive handles, with methods for their installation being highly valued. Here a new, powerful strategy to unmask a reactive protein aldehyde is presented. A genetically encoded caged glyoxyl aldehyde, situated in solvent-accessible locations, can be rapidly decade through treatment with just one equivalent of allylpalladium(II) chloride dimer at physiological pH. The protein aldehyde can undergo subsequent oxime ligation for site-selective protein modification. Quick yet mild conditions, orthogonality and powerful exposed reactivity make this strategy of great potential in protein modification

When to reveal what you feel:How emotions towards antagonistic out-group and third party audiences are expressed strategically

In intergroup conflicts, expressed emotions influence how others see and react to those who express them. Here, we investigated whether this in turn implies that emotions may be expressed strategically. We tested whether emotion expression can differ from emotion experience, and whether emotion expression (more than emotion experience) is used to pursue specific goals. Specifically, we focused on whether support-seeking emotions (fear and sadness) are used to call for support from a powerful third party and contempt to distance from an antagonistic out-group. In two studies, using the same ostensible conflict, we manipulated whether participants communicated their emotions towards the out-group (no vs. yes) and third party (no vs. yes) and employed a between-subjects design in Study 1 (N = 86) and a within-subjects design in Study 2 (N = 83). In both studies, we found that members of a disadvantaged group expressed reduced support-seeking emotions towards the out-group than they experienced (i.e., in conditions without an audience), providing support for the assumption that emotion expression does not necessarily reflect experience. Further, in Study 2, we found in line with expectations that the goal to call for support was more important in the communication with the third party than with the antagonistic out-group. The goal was best predicted by expressed support-seeking emotions, providing support for the assumption that emotion expression is used to pursue goals. Interestingly, we only found this association for a beneficial goal (i.e., calling for support) and not for distancing, a destructive goal. These results support the proposed strategic use of emotion expression and as such advance our understanding of the function of expressed emotions

Predicting aggressive collective action based on the efficacy of peaceful and aggressive actions

We examine whether aggressive forms of collective action are predicted by their perceived efficacy and the perceived efficacy of peaceful collective action, and whether the two predictors interact. We present data from surveys examining support for and tendencies toward aggressive collective action among university students opposed to increases in tuition fees in Britain (Study 1), and support for suicide bombings against Israeli civilians among Palestinians during the second Intifada (Study 2). Our results reveal an interaction between the efficacy of peaceful and aggressive collective actions: the more efficacious aggression is perceived to be, the greater its appeal and the less it is assuaged by the efficacy of peaceful action. This implies that 1) people may consider aggressive action whenever it works, even if peaceful action is efficacious, and 2) people may consider aggressive action even when it seems unpromising, if peaceful action is not efficacious, in an apparent nothing-to-lose strategy.PostprintPeer reviewe
