Cellulitis, a common subcutaneous infection, is influenced by host, pathogen, and environmental factors. Previous studies have shown seasonal patterns in adult cellulitis, suggesting temperature as a risk factor. This study investigated seasonal patterns in paediatric cellulitis in Jerusalem’s semi-arid climate. A single-center retrospective cohort study reviewed medical records of 2,219 hospitalized children under 18 with cellulitis between 1990 and 2020. Demographic, clinical, temperature, and humidity data were collected. Results revealed a significant sinusoidal pattern for limb cellulitis (LC) but for other body sites, with summer peaks and winter nadirs (P < 0.01). August showed the highest incidence, tripling that of February. Age groups 1-6 and 6-12 demonstrated the largest seasonal differences (P = 0.004, P = 0.008). Over three decades, paediatric hospitalized LC cases increased by 71% (P < 0.001), correlating with rising temperatures. Elevated ambient temperature seven days prior to diagnosis was a risk factor for LC development (OR = 1.02, P = 0.03). This study highlights the cyclic seasonal pattern of paediatric LC, peaking in summer. The significant increase in cases over time, coupled with rising temperatures, suggests climate change as a contributing factor. These findings could inform public health strategies for cellulitis prevention and management in children.

Using longitudinal data on teams and quality competition results, this study examines the impact of team and task familiarity on brewing excellence in the Japanese sake industry from 1956 to 2018. Sake production involves teamwork at every stage, but while some teams work together long term, others experience high turnover. The study highlights two factors: team familiarity, the collective experience of working together, and task familiarity, the individual experience of the task. High familiarity can strengthen team bonds and improve teamwork, but it can also limit the inflow of new knowledge and thus hinder innovation. This study uses data from national quality competitions and brewer lists, and considers the Great East Japan Earthquake of 2011 as an external shock to address endogeneity and estimate the causal relationship between familiarity and competition outcomes. The empirical results show that increases in both team and task familiarity are negatively associated with quality superiority.

This paper engages with a series of recent literatures that examine how feminist and queer movements have become agents of nationalism, neoliberalism, and global wars. I argue that, while the critique of intersectionality has attempted to curtail the reproductions of such violence within feminism, it too has not been able to resist cooptations into nationalist and capitalist forms of power. Developing an epistemological critique of intersectionality, I arrive at an analysis of identity politics as an elemental identification with phallic power that erases the feminine. Building on the works of Elizabeth Grosz, Wendy Brown, and Luce Irigaray, I suggest that at the core of such feminist alliances with domination lies an unresolved relation to feminine desire as the desire for a non-identitarian politics.

The delta invariant interprets the criterion for the K-(poly)stability of log terminal Fano varieties. In this paper, we determine local delta invariants for all weak del Pezzo surfaces with the anti-canonical degree $\geq 5$.

Limited academic career prospects are pushing PhD graduates in political science and other disciplines to nonacademic careers. Understanding the mismatch between student and supervisor perceptions of doctoral career training is a starting point for suggesting program reforms. This research note examines the perceptions of PhD students and supervisors on doctoral career training. We compare results from two surveys of English-speaking Canadian universities on doctoral political science programs; one surveys PhD students and the other surveys supervisors. These survey results suggest that 1) students are more aware of the limited academic job market and interested in nonacademic careers than supervisors realize; 2) supervisors are unaware of the sunk costs PhD students face; 3) supervisors and students have different preferences for change in doctoral programs; and 4) students overestimate supervisors’ confidence in preparing them for nonacademic careers. Changes in program design can better meet student needs in these PhD programs.
