Seeking Structure in Social Organization: Compensatory Control and the Psychological Advantages of Hierarchy

Hierarchies are a ubiquitous form of human social organization. I hypothesized that one reason for hierarchies’ prevalence might be that core motivational needs for order and control make hierarchies psychologically appealing—because of the structure they offer—relative to other, less structured forms of social organization. This hypothesis is rooted in compensatory control theory (Kay et al., 2008), which posits that individuals have a basic need to perceive the world as orderly and structured. Therefore, personal and external sources of control are substitutable, inasmuch as they both serve the superordinate goal of believing that the world operates in an orderly fashion. An initial study confirmed that hierarchies are perceived as more structured and orderly relative to egalitarian arrangements. In five subsequent experiments, I threatened participants’ sense of personal control to increase their need to rely on external structure. Participants who lacked control perceived more hierarchy occurring in ambiguous social situations (Study 2) and preferred hierarchy more strongly in business contexts (Studies 3-4). Two studies tested my account that hierarchies are appealing because of their structure. Preference for hierarchy was higher among individuals high in Personal Need for Structure (PNS), and control threat increased preference for hierarchy even among low-PNS participants (Study 4). Importantly, framing a hierarchy as unstructured reversed the previous effects, so that participants who lacked control now found hierarchy unappealing (Study 5). A final study found that hierarchy-enhancing careers were more appealing after control threat, even when those jobs were low-status (Study 6). I discuss how the compensatory control account for the allure of hierarchies complements and extends other influential theories of hierarchy maintenance, such as Social Dominance Theory and System Justification Theory.1 yea

Women and (dis)interest in government: How the status quo affects attitudes toward female politicians and intentions to participate in politics

When people are motivated to justify their socio-political systems they come to view the current status quo as the most desirable status quo--a process termed injunctification (Kay et al., 2009). Here, two studies suggest that injunctification processes can perpetuate gender inequalities in politics. In Study 1, I manipulated the system justification (SJ) motive of 64 female undergraduates and presented information suggesting there are many or few women in federal politics. Participants with their SJ motive heightened and who read there were many women more showed more egalitarian attitudes compared to other conditions. Study 2 (90 female undergraduates) again manipulated the SJ motive and manipulated the status quo about the number of women in politics. Participants with a heightened SJ motive who read there would soon be many women in politics reported more personal political interest, compared to other conditions. Implications for inequality and System Justification Theory are discussed

Virtual cardiac rehabilitation: A rapid shift in care delivery in response to the COVID-19 Pandemic

Cardiac rehabilitation is an integral part of recovery from a critical cardiac life event. This preventative strategy involves exercise rehabilitation, education, lifestyle modification, and self-management coaching – preparing patients for lifelong changes. Prior to the COVID-19 pandemic, these activities were supervised by clinicians in-person, on hospital grounds, and in large groups. However, due to pandemic regulations in Canada imposed in March 2020, all in-person group activities were restricted. Within the first two months of the pandemic, almost half of cardiac rehabilitation services in Canada closed and half of their employees were deployed to other areas. To continue to provide patient care and ensure high-quality patient experience and recovery, cardiac rehabilitation services in Fraser Health, British Columbia rapidly transitioned to exclusively virtual methods of care delivery. Two years later, we are still providing this virtual model of care. This case study reflects on the experience of virtual care delivery of cardiac rehabilitation by participants and health providers. It outlines the process, the challenges, and the outcomes experienced with shifting to a new standard of care. The virtual participation rates showed a slight increase, with a significant reduction in time to access care, and increased adherence to the rehabilitation program. Overall patient satisfaction and provider experience continue to be positive. The consensus is that cardiac rehabilitation should not be optional, even during a global crisis.

SnTox3 Acts in Effector Triggered Susceptibility to Induce Disease on Wheat Carrying the Snn3 Gene

The necrotrophic fungus Stagonospora nodorum produces multiple proteinaceous host-selective toxins (HSTs) which act in effector triggered susceptibility. Here, we report the molecular cloning and functional characterization of the SnTox3-encoding gene, designated SnTox3, as well as the initial characterization of the SnTox3 protein. SnTox3 is a 693 bp intron-free gene with little obvious homology to other known genes. The predicted immature SnTox3 protein is 25.8 kDa in size. A 20 amino acid signal sequence as well as a possible pro sequence are predicted. Six cysteine residues are predicted to form disulfide bonds and are shown to be important for SnTox3 activity. Using heterologous expression in Pichia pastoris and transformation into an avirulent S. nodorum isolate, we show that SnTox3 encodes the SnTox3 protein and that SnTox3 interacts with the wheat susceptibility gene Snn3. In addition, the avirulent S. nodorum isolate transformed with SnTox3 was virulent on host lines expressing the Snn3 gene. SnTox3-disrupted mutants were deficient in the production of SnTox3 and avirulent on the Snn3 differential wheat line BG220. An analysis of genetic diversity revealed that SnTox3 is present in 60.1% of a worldwide collection of 923 isolates and occurs as eleven nucleotide haplotypes resulting in four amino acid haplotypes. The cloning of SnTox3 provides a fundamental tool for the investigation of the S. nodorum-wheat interaction, as well as vital information for the general characterization of necrotroph-plant interactions.This work was supported by USDA-ARS CRIS projects 5442-22000-043-00D and 5442-22000-030-00D

Impact of perceived interpersonal similarity on attention to the eyes of same‑race and other‑race faces

This research was supported by the Social Sciences and Humanities Research Council of Canada (435-2013-0992) and Canada Foundation for Innovation (9297) Grants to Kerry Kawakami.One reason for the persistence of racial discrimination may be anticipated dissimilarity with racial outgroup members that prevent meaningful interactions. In the present research, we investigated whether perceived similarity would impact the processing of same-race and other-race faces.Specifically, in two experiments, we varied the extent to which White participants were ostensibly similar to targets via bogus feedback on a personality test. With an eye tracker, we measured the effect of this manipulation on attention to the eyes, a critical region for person perception and face memory. In Experiment 1, we monitored the impact of perceived interpersonal similarity on White participants’ attention to the eyes of same-race White targets. In Experiment 2, we replicated this procedure, but White participants were presented with either same-race White targets or other-race Black targets in a between-subjects design. The pattern of results in both experiments indicated a positive linear effect of similarity—greater perceived similarity between participants and targets predicted more attention to the eyes of White and Black faces. The implications of these findings related to top-down effects of perceived similarity for our understanding of basic processes in face perception, as well as intergroup relations, are discussed.Social Sciences and Humanities Research Council of Canada (SSHRC) 435-2013-0992Canada Foundation for Innovation CGIAR 929

The Cysteine Rich Necrotrophic Effector SnTox1 Produced by Stagonospora nodorum Triggers Susceptibility of Wheat Lines Harboring Snn1

The wheat pathogen Stagonospora nodorum produces multiple necrotrophic effectors (also called host-selective toxins) that promote disease by interacting with corresponding host sensitivity gene products. SnTox1 was the first necrotrophic effector identified in S. nodorum, and was shown to induce necrosis on wheat lines carrying Snn1. Here, we report the molecular cloning and validation of SnTox1 as well as the preliminary characterization of the mechanism underlying the SnTox1-Snn1 interaction which leads to susceptibility. SnTox1 was identified using bioinformatics tools and verified by heterologous expression in Pichia pastoris. SnTox1 encodes a 117 amino acid protein with the first 17 amino acids predicted as a signal peptide, and strikingly, the mature protein contains 16 cysteine residues, a common feature for some avirulence effectors. The transformation of SnTox1 into an avirulent S. nodorum isolate was sufficient to make the strain pathogenic. Additionally, the deletion of SnTox1 in virulent isolates rendered the SnTox1 mutated strains avirulent on the Snn1 differential wheat line. SnTox1 was present in 85% of a global collection of S. nodorum isolates. We identified a total of 11 protein isoforms and found evidence for strong diversifying selection operating on SnTox1. The SnTox1-Snn1 interaction results in an oxidative burst, DNA laddering, and pathogenesis related (PR) gene expression, all hallmarks of a defense response. In the absence of light, the development of SnTox1-induced necrosis and disease symptoms were completely blocked. By comparing the infection processes of a GFP-tagged avirulent isolate and the same isolate transformed with SnTox1, we conclude that SnTox1 may play a critical role during fungal penetration. This research further demonstrates that necrotrophic fungal pathogens utilize small effector proteins to exploit plant resistance pathways for their colonization, which provides important insights into the molecular basis of the wheat-S. nodorum interaction, an emerging model for necrotrophic pathosystems
