More Is More or More Is Less? Parental Financial Investments during College
Evidence shows that parental financial investments increase college attendance, but we know little about how these investments shape postsecondary achievement. Two theoretical frameworks suggest diametric conclusions. Some studies operate from a more-is-more perspective in which children use calculated parental allocations to make academic progress. In contrast, a more-is-less perspective, rooted in a different model of rational behavior, suggests that parental investments create a disincentive for student achievement. I adjudicate between these frameworks, using data from nationally representative postsecondary datasets to determine what effect financial parental investments have on student GPA and degree completion. The findings suggest seemingly contradictory processes. Parental aid decreases student GPA, but it increases the odds of graduating—net of explanatory variables and accounting for alternative funding. Rather than strategically using resources in accordance with parental goals, or maximizing on their ability to avoid academic work, students are satisficing: they meet the criteria for adequacy on multiple fronts, rather than optimizing their chances for a particular outcome. As a result, students with parental funding often perform well enough to stay in school but dial down their academic efforts. I conclude by highlighting the importance of life stage and institutional context for parental investment.

Hegemonic Femininities and Intersectional Domination
We examine how two sociological traditions account for the role of femininities in social domination. The masculinities tradition theorizes gender as an independent structure of domination; consequently, femininities that complement hegemonic masculinities are treated as passively compliant in the reproduction of gender. In contrast, Patricia Hill Collins views cultural ideals of hegemonic femininity as simultaneously raced, classed, and gendered. This intersectional perspective allows us to recognize women striving to approximate hegemonic cultural ideals of femininity as actively complicit in reproducing a matrix of domination. We argue that hegemonic femininities reference a powerful location in the matrix from which some women draw considerable individual benefits (i.e., a femininity premium) while shoring up collective benefits along other dimensions of advantage. In the process, they engage in intersectional domination of other women and even some men. Our analysis re-enforces the utility of analyzing femininities and masculinities from within an intersectional feminist framework.

The Stigma of ADHD
Despite the increasing prevalence of Attention-Deficit Hyperactivity Disorder (ADHD), little sociological research has focused on effects of diagnosis in schools. This study, which is grounded in the modified labeling approach, relies on three waves of Early Childhood Longitudinal Study (ECLS-K:2011) data to determine if teachers evaluate the academic performance of ADHD students as less promising than non-diagnosed peers. Results indicate that teachers are more likely to rate ADHD students as performing below grade level and are less likely to acknowledge these students as performing above grade level—regardless of demonstrated ability on subject-specific tests. The latter finding is, in part, a function of real and/or perceived behaviors in the classroom that inform teachers' grade-level performance ratings. We argue that diagnosis may be a double-edged sword for children and their families, as it can provide access to special resources in the school but may activate teachers' negative stereotypes about diagnosed students.

Stearoyl-CoA Desaturase inhibition reverses immune, synaptic and cognitive impairments in an Alzheimer’s disease mouse model
The defining features of Alzheimer’s disease (AD) include alterations in protein aggregation, immunity, lipid metabolism, synapses, and learning and memory. Of these, lipid abnormalities are the least understood. Here, we investigate the role of Stearoyl-CoA desaturase (SCD), a crucial regulator of fatty acid desaturation, in AD pathogenesis. We show that inhibiting brain SCD activity for 1-month in the 3xTg mouse model of AD alters core AD-related transcriptomic pathways in the hippocampus, and that it concomitantly restores essential components of hippocampal function, including dendritic spines and structure, immediate-early gene expression, and learning and memory itself. Moreover, SCD inhibition dampens activation of microglia, key mediators of spine loss during AD and the main immune cells of the brain. These data reveal that brain fatty acid metabolism links AD genes to downstream immune, synaptic, and functional impairments, identifying SCD as a potential target for AD treatment.
Alzheimer’s disease (AD) is characterized by lipid abnormalities which are not well understood. Here, the authors investigate the role of Stearoyl-CoA desaturase (SCD) in a mouse model of AD. They show that inhibiting SCD activity induces major brain and immune cell transcriptional changes and restores dendritic structure and learning and memory.

\Good Girls\: Gender, Social Class, and Slut Discourse on Campus
Women's participation in slut shaming is often viewed as internalized oppression: they apply disadvantageous sexual double standards established by men. This perspective grants women little agency and neglects their simultaneous location in other social structures. In this article we synthesize insights from social psychology, gender, and culture to argue that undergraduate women use slut stigma to draw boundaries around status groups linked to social class—while also regulating sexual behavior and gender performance. High-status women employ slut discourse to assert class advantage, defining themselves as classy rather than trashy, while low-status women express class resentment—deriding rich, bitchy sluts for their exclusivity. Slut discourse enables, rather than constrains, sexual experimentation for the high-status women whose definitions prevail in the dominant social scene. This is a form of sexual privilege. In contrast, low-status women risk public shaming when they attempt to enter dominant social worlds.
