Predicting university performance in psychology: the role of previous performance and discipline-specific knowledge
Recent initiatives to enhance retention and widen participation ensure it is crucial to understand the factors that predict students' performance during their undergraduate degree. The present research used Structural Equation Modeling (SEM) to test three separate models that examined the extent to which British Psychology students' A-level entry qualifications predicted: (1) their performance in years 1-3 of their Psychology degree, and (2) their overall degree performance. Students' overall A-level entry qualifications positively predicted performance during their first year and overall degree performance, but negatively predicted their performance during their third year. Additionally, and more specifically, students' A-level entry qualifications in Psychology positively predicted performance in the first year only. Such findings have implications for admissions tutors, as well as for students who have not studied Psychology before but who are considering applying to do so at university

Perceptions of Social Influence When Messages Favour 'Us' Versus 'Them': A Closer Look at the Social Distance Effect
The third-person effect (TPE) is the tendency for individuals to assume that persuasive communications have a stronger effect on other people than on themselves. In turn the social distance effect (SDE) is the tendency for this TPE to increase with the psychological distance between self and comparator. Two experiments showed that the SDE is moderated by whether the message favours the ingroup or the outgroup, holding all other content constant. In Study 1, male and female participants read a message arguing that either women were better drivers than men or vice versa, and then indicated how much they thought themselves, ingroup members, outgroup members and society would be influenced. The results indicate that for the pro-outgroup message the SDE was found. However, for the pro-ingroup message the SDE was reversed with ingroup members perceived as more influenced than all other targets, including the self. Study 2 replicated this finding using minimal groups, which eliminated the effects of prior stereotypes about male and female drivers. Across both studies the self was perceived as relatively invulnerable to influence regardless of message bias
Justice for whom, exactly? Beliefs in justice for the self and various others.
The present studies examine why people think the world is more just to themselves than to others generally. Beliefs in justice for the self were uniquely associated with psychological adjustment, consistent with the theoretical motive to believe in justice for the self ( Studies 1 and 2). However, this "justice motive" did not appear to affect the relative strength of justice beliefs. Instead, self-other differences in justice beliefs appeared to reflect objective assessments of the justice received by various demographics. Undergraduates believed the world to be more just to themselves than to others but not their undergraduate peers specifically ( Study 1). Participants of both genders believed the world to be more just to men, and to themselves, than to women ( Study 2). Women did not exempt themselves individually from injustice but believed, similar to men, that undergraduate women receive as much justice as men ( Study 3)
Keeping it to ourselves: Effects of audience size and composition on reactions to criticisms of the ingroup
Criticism is an important aspect of communication within and between groups, but reactions to criticism of groups have been little studied. Past research has shown that criticism elicits greater sensitivity when made by an outgroup member, compared to an ingroup member. Two experiments were conducted to examine how this intergroup sensitivity effect (ISE) is affected by the context of the criticism. Experiment I showed that the ISE occurs in a private context, but disappears when it is clear that the criticism is made to a large public audience. Experiment 2 investigated intragroup criticism and manipulated both audience size and audience composition. Results showed that ingroup, criticism elicited greater sensitivity and less favorable evaluations of the speaker when made to an outgroup rather than an ingroup audience. The results highlight strategic considerations and tacit protocols governing the criticism of groups
Reactions to internal and external criticism of outgroups: Social convention in the intergroup sensitivity effect
Recent research has documented the intergroup sensitivity effect (ISE) whereby people respond more favorably to internal versus external criticism of their group. The present studies examine the reactions of bystanders who do not belong to the criticized group and whose reactions are therefore more likely to be informed by social conventions than by defensiveness. Studies I and 2 presented British participants with criticisms of Australians, manipulating their ostensible source. These British bystanders exhibited the ISE, responding more favorably to the speaker and comments when the critic was Australian rather than non-Australian. These responses were driven by the perceived motives of speakers rather than their level of experience with the group (Study 2). Study 3 provides direct evidence that internal criticism is more conventionally acceptable than is external criticism

LGR5 promotes survival in human colorectal adenoma cells and is upregulated by PGE2: Implications for targeting adenoma stem cells with nsaids
Cyclooxygenase-2 is overexpressed in the majority of colorectal tumours leading to elevated levels of prostaglandin E2 (PGE2), promoting many hallmarks of cancer. Importantly, PGE2 is reported to enhance Wnt/Ī²-catenin signalling in colorectal carcinoma cells and in normal haematopoietic stem cells where it promotes stem cell function. Although Wnt signalling plays a crucial role in intestinal stem cells, the relationship between PGE2 and intestinal stem cells is unclear. Given that the key intestinal cancer stem cell marker LGR5 (leucine-rich G-protein coupled receptor 5) is a Wnt target and PGE2 enhances Wnt signalling, the focus of this study was to investigate whether PGE2 regulated LGR5 expression in colorectal adenoma cells and whether LGR5 was important for tumour cell survival. PGE2 upregulated LGR5 protein in adenoma (RG/C2) and carcinoma (DLD-1) cell lines. LGR5 knockdown induced cell death in RG/C2 and AA/C1 adenoma cells, suggesting that LGR5 has an important survivalpromoting role in adenoma cells. Indeed, we detected LGR5 protein expression in 4 of 4 human adenoma cell lines. Furthermore, LGR5 small interfering RNA inhibited the survival-promoting effects of PGE2 in RG/C2, suggesting that PGE2 promotes adenoma cell survival, at least in part, by increasing LGR5 expression. These studies, therefore, show the first link between PGE2 and LGR5 in human colorectal adenoma and carcinoma cells and demonstrate a survival-promoting role of LGR5. As non-steroidal anti-inflammatory drugs (NSAIDs) cause adenomas to regress in FAP patients, these studies could have important implications for the mechanism by which NSAIDs are chemopreventive, as lowering PGE2 levels could reduce LGR5 expression and survival of LGR5+ adenoma stem cells.
