“Boys Love Boy Toys”: a qualitative study exploring the role of fathers in young boys’ gendered toy preferences
Authors: Tesolin Julia , Lo Elsa 
Published: November 2023

AbstractChildren come to understand the concept of gender and learn to differentiate roles and norms on the basis of gender in early childhood. By interacting with individuals in their social contexts (i.e., family and peers), children are taught about gender norms and expectations, and as a result, learn to negotiate their own identities within different contexts. Parents have an especially important role in how children come to understand their own gender identity, as they have the ability to shape their childrens’ behaviors by endorsing certain gender stereotypes (e.g., girls wear pink, and boys play with trucks). For young boys, their fathers are a key socialization agent in their gender development, as they convey both implicitly and explicitly, gender-appropriate ways of being. Fathers may endorse ideas of traditional masculinity, which constrain boys to conform to the expected male norms, and discourages them from engaging in perceived feminine behaviors, such as cross-gender play. Accordingly, young boys are often expected to prove their manhood by marking their masculinity against femininity, in a power struggle where they are trying to get their gender right. Based on established and current literature in the field of gender identity development and masculinity in early childhood, this qualitative study aimed to explore young boys’ existing working schema of masculinity and the role that their fathers play in shaping it. Participants included six father–son pairs, with boys (ages 4–6) and their fathers (ages 34–37). Fathers were first asked to complete an adapted version of the Child-Rearing Sex-Role Attitude Scale, which assessed their attitudes and beliefs about gender-related toys, activities, and behaviors. Semi-structured interviews were then conducted with the father–son pairs, where they participated in a series of toy-preference activities in a virtual game. Descriptive coding and content analysis were used to analyze the responses boys provided for their toy preferences. Boys reported having a more stereotyped definition of “girl toys” than of “boy toys”, as reflected in their choices of toys that they felt that only girls would like to play with. Fathers’ self-described beliefs reported on the Child-Rearing Sex-Role Attitude Scale were similarly reflected in their behaviours and comments during the interviews with their sons, such that fathers who shared stereotypical beliefs about gender-related behaviours and activities on the scale, engaged in behaviours which corresponded to their beliefs when interacting with their sons. Implications for families and educators are discussed.
Performance Evaluation on Parallel Speculation-Based Construction of a Binary Search Tree
Authors: Hirata Hiroaki , Nunome Atsushi 
Published: November 2023

AbstractBinary search trees (BSTs) are one of the most important data structures in the field of computer science. We may easily write a parallel construction program of a BST by extending the sequential algorithm straightly. However, in such conventional approaches, the order of nodes inserted into a BST is determined dynamically, depending on the occasional state of the parallel thread execution. It results in a BST with a different structure (node position) generated on every execution of the parallel program. On the other hand, we have been developing parallel construction schemes of the BST with the same structure as a BST generated by the sequential algorithm. One is the speculatively parallel construction of a BST. And another is the purely (non-speculatively) parallel construction, but it was derived through the concept of thread-level speculation. This paper evaluates the performances of those construction schemes on several types of shared-memory multiprocessors. For the large enough size of BST, our new parallel programs can construct a BST with always the same structure on a little lower or sometimes higher performance than the program that makes a BST with a different structure on every execution. And in contrast with the general expectation that simply enlarging the size of parallel tasks increases misspeculation and damages the performance, we found that it sometimes enhances the performance of speculatively parallel execution.
Wellbeing Convene during COVID-19: A pilot intervention for improving wellbeing and social connectedness for staff, students, residents, and faculty

Published: November 2023

Abstract

Background:
Canada is facing its worst crisis among healthcare workers in recent healthcare history. Anxiety, depression, suicidal ideation, and severe burnout are higher than before the COVID-19 pandemic. University Faculties of Medicine (FoMs) are vital to healthcare systems. Not only are they responsible for training personnel, but clinicians and staff from FoMs often work directly within healthcare systems. FoMs include students, staff, residents, faculty members, residents, researchers, and others, many experiencing higher stress levels due to pandemic tensions. Most FoMs emphasize cognitive and psychomotor learning needs. On the other hand, affective learning needs are not as well addressed within most FoMs. Finding innovative means to ameliorate mental and emotional health status, particularly at this critical juncture, will improve health and wellness, productivity, and retention. This article discusses a pilot program, Wellbeing Convene during COVID-19, in a Canadian FoM, which aimed to (1) provide staff, faculty, residents, and students with a toolkit for greater wellbeing and (2) build a sense of community during isolating times.

Results:
Participants found the program beneficial in both regards. We recommend that these kinds of programs be permanently available to all members in FoMs, at no cost. Wellness programs alone, however, will not solve the root causes of mental and emotional stress, often based on concerns related to finances, hierarchical workplace structures, and nature of the work itself, among other factors.

Conclusion:
Addressing the mental and emotional health of people in FoMs is vital to improving productivity and reducing stress of FoMs, healthcare professionals, and, ultimately, patients.
Deciphering stable water isotope records of firn cores from a strongly maritime, high-accumulation site on the Antarctic Peninsula

AbstractStable water isotope records of six firn cores retrieved from two adjacent plateaus on the northern Antarctic Peninsula between 2014 and 2016 are presented and investigated for their connections with firn-core glacio-chemical data, meteorological records and modelling results. Average annual accumulation rates of 2500 kg m−2 a−1 largely reduce the modification of isotopic signals in the snowpack by post-depositional processes, allowing excellent signal preservation in space and time. Comparison of firn-core and ECHAM6-wiso modelled δ18O and d-excess records reveals a large agreement on annual and sub-annual scales, suggesting firn-core stable water isotopes to be representative of specific synoptic situations. The six firn cores exhibit highly similar isotopic patterns in the overlapping period (2013), which seem to be related to temporal changes in moisture sources rather than local near-surface air temperatures. Backward trajectories calculated with the HYSPLIT model suggest that prominent δ18O minima in 2013 associated with elevated sea salt concentrations are related to long-range moisture transport dominated by westerly winds during positive SAM phases. In contrast, a broad δ18O maximum in the same year accompanied by increased concentrations of black carbon and mineral dust corresponds to the advection of more locally derived moisture with northerly flow components (South America) when the SAM is negative.
Transnational Jewish Politics in the Interwar Period: Berlin Rabbi Joachim Prinz and the Yugoslav Zionists
Authors: Jünger David , Vulesica Marija 
Published: November 2023

AbstractThis article explores the journey of Berlin Rabbi Joachim Prinz (1902–1988) to Yugoslavia at the invitation of Zagreb Zionist leader Lavoslav Schick (1881–1941) in late 1935. It examines the transnational cooperation between German and Yugoslav Zionists in the interwar period and their efforts to cope with the plight of German and southeastern European Jewry alike. Although Jewish representatives of different countries cooperated intensively during the interwar period, we know little about it. Thus, this article intervenes in current research on European Jewish history and contributes to a growing interest in the transnational entanglements of European Jewry and Jewish politics in the 1930s and early 1940s by focusing on two important protagonists of Jewish interwar politics in Germany and Yugoslavia.
Censoring Our History
Authors: Lownie Andrew 
Published: November 2023

AbstractAndrew Lownie recounts how he became the victim of state surveillance as a result of his successful efforts to secure the release of the personal diaries and letters of Dickie and Edwina Mountbatten – bought by the University of Southampton with public funds to be open to researchers – in what became the largest-ever release of material under Freedom of Information (FOI), 33,000 pages, but which personally cost him over £400,000 in legal fees. Drawing on his own research experiences, he also describes the failure of government departments to deposit records at the National Archives as required by statute, the techniques public authorities use to frustrate FOI requests and suggests how FOI could be improved. All of this curation, he argues, leads to a distortion of the historical record and the censoring of our history.

Abstract
Given the increasing demand for high-quality food and protein, global food security remains a challenge, particularly in the face of global change. However, since agriculture, food and water security are inextricably linked, they need to be examined via an interdisciplinary lens. Sociohydrology was introduced from a post-positivist perspective to explore and describe the bidirectional feedbacks and dynamics between human and water systems. This review situates sociohydrology in the agricultural domain, highlighting its contributions in explaining the unintended consequences of water management interventions, addressing climate change impacts due to/on agriculture and incorporating human behaviour into the description of agricultural water systems. Sociohydrology has combined social and psychological insights with novel data sources and diverse multi-method approaches to model human behaviour. However, as agriculture and agriculturalists face global change, sociohydrology can better use concepts from resilience thinking more explicitly to identify gaps in terms of desirable properties in resilient agricultural water systems, potentially informing more holistic climate adaptation policy.

AbstractLake surface water temperature (LSWT) is a key parameter in lake energy budget and is highly vulnerable to climate change. However, the long‐term trends in LSWT across China and their driving factors remain uncertain. Here, we used a calibrated lake model to simulate LSWT over 1979–2018 for 91 large lakes (>100 km2) across China. Simulations reveal an overall LSWT warming trend (0.040°C yr−1, p < 0.05), but with large spatial variations. The majority of these lakes show significant warming trends (84%, 0.053°C yr−1), while a significant cooling trend is found in the seven lakes in the northwestern Tibetan Plateau (−0.064°C yr−1). LSWT of approximately 42% of the lakes increases more rapidly than the corresponding ambient air temperature. Regionally, the warming trend is highest for lakes in the Eastern Plain (0.049°C yr−1) and the lowest in the Yunnan‐Guizhou Plateau (0.016°C yr−1). The increases in simulated LSWT also vary across seasons, with a higher rate in winter and spring than in summer and autumn. Changes in air temperature, downward longwave radiation, and wind speed are the most important climatic drivers for LSWT changes. Lake surface warming could be more rapid under future global warming, necessitating greater attention to lake‐atmosphere interactions.
Wave Attenuation by Sea Ice in the Arctic Marginal Ice Zone Observed by Spaceborne SAR
Authors: Huang Bing Qing , Li Xiao‐Ming 
Published: November 2023

AbstractAttenuation of ocean waves by ice is a crucial process of the interaction between waves and sea ice in marginal ice zone (MIZ), while such interaction can contribute to the retreating of sea ice in the Arctic. Based on the retrieved two‐dimensional ocean wave spectra by spaceborne Synthetic Aperture Radar, we investigated the attenuation of ocean waves in the MIZ in Svalbard and Greenland. The results show that the energy attenuation rate ranges from 0.126 × 10−4/m to 0.618 × 10−4/m. Quantitative analysis suggests that the attenuation rate is significantly related to wave height and peak wave period of coming waves. It is further found that the waves decay faster in the area with ice thickness exceeding 0.5 m. We compared the derived wave attenuation rates in the present study with those in previous studies based on in situ measurements, which reveals that waves are becoming less attenuated by sea ice in the Arctic.
Block‐Grain Phase Transition in Rock Avalanches: Insights From Large‐Scale Experiments

AbstractKnowledge of the processes and effects of the block‐grain phase transition in a fragmented system is essential for investigating rock avalanches. Several series of experiments are performed with a very large apparatus, using a jointed block, simulated by an assembly of packed breakable subblocks varying in configuration, as an analog for brittle rock. The analog jointed block is released from a hopper, moves on two inclined flumes with different slopes, and finally deposits on a horizontal platform. The block‐grain phase transition occurs, caused by subblock collisions and explosive impacts with the flume bottom. The dynamic behavior, seismic signal, fragment characteristic, and deposit structure of the analog material are determined. Our results demonstrate that fragmentation influences energy dissipation and momentum transfer, as well as subsequent flow and emplacement processes. A nonunified and piecewise relationship between the fragmentation degree and friction coefficients is observed. We ascribe this nonunified relationship to the varying dynamics and runout regimes that different configurations of jointed blocks undergo. The positive or negative feedback on energy generated by fragmentation is closely associated with the energy budget involved in this fragmented system, which depends substantively on the block configuration. Particularly, for flatter or larger jointed blocks, despite increased fragmentation absorbing the available energy for runout, it simultaneously changes the runout regime toward a more energy‐efficient one, thus instigating positive feedback. Our study further highlights the contribution of post‐fragmentation granular flow to the energy system.

Abstract
Background/objectives
Nutrition and obesity researchers often dichotomize or discretize continuous independent variables to conduct an analysis of variance to examine group differences. We describe consequences associated with dichotomizing and discretizing continuous variables using two cross-sectional studies related to nutrition.

Subjects/methods
Study 1 investigated the effects of health literacy and nutrition knowledge on nutrition label accuracy (n = 612). Study 2 investigated the effects of cognitive restraint and BMI on fruit and vegetable (F/V) intake (n = 586). We compare analytic approaches where continuous independent variables were either discretized/dichotomized or analyzed as continuous variables.

Results
In Study 1, dichotomization of health literacy and nutrition knowledge for 2 × 2 ANOVA revealed health literacy had an effect on nutrition label accuracy. Nutrition knowledge has an effect on nutrition label accuracy, but the health literacy by nutrition knowledge interaction was not significant. When analyzed using regression, the nutrition knowledge effect was significant. The simple effect of health literacy was also significant when health literacy equals zero. Finally, the quadratic effect of health literacy was negative and significant. In Study 2, dichotomization and discretization of cognitive restraint and BMI were used for three ANOVAs, which discretized BMI in three ways. For all ANOVAs, the BMI main effect for predicting fruit and vegetable intake was significant, the interaction between BMI and cognitive restraint was non-significant, and cognitive restraint was only significant when both variables were dichotomized. When analyzed using regression, the continuous mean-centered variables, and their interaction each significantly predicted F/V intake.

Conclusions
Dichotomizing continuous independent variables resulted in distortions of effect sizes across studies, an inability to assess the quadratic effect of health literacy, and an inability to detect the moderating effect of BMI. We discourage researchers from dichotomizing and discretizing continuous independent variables and instead use multiple regression to examine relationships between continuous independent and dependent variables.

AbstractThe placenta plays a role in fetal brain development, and pregnancy and birth complications can be signs of placental dysfunction. Birth asphyxia is associated with smaller head size and higher risk of developing schizophrenia (SZ), but whether birth asphyxia and placental genomic risk factors associated with SZ are related and how they might impact brain development is unclear. 433 adult patients with SZ and 870 healthy controls were clinically evaluated and underwent brain magnetic resonance imaging. Pregnancy and birth information were obtained from the Medical Birth Registry of Norway. Polygenic risk scores (PRS) from the latest genome-wide association study in SZ were differentiated into placental PRS (PlacPRS) and non-placental PRS. If the interaction between PRSs and birth asphyxia on case-control status was significant, neonatal head circumference (nHC) and adult intracranial volume (ICV) were further evaluated with these variables using multiple regression. PlacPRS in individuals with a history of birth asphyxia was associated with a higher likelihood of being a patient with SZ (t = 2.10, p = 0.018). We found a significant interaction between PlacPRS and birth asphyxia on nHC in the whole sample (t = −2.43, p = 0.008), with higher placental PRS for SZ associated with lower nHC in those with birth asphyxia. This relationship was specific to males (t = −2.71, p = 0.005) and also found with their adult ICV (t = −1.97, p = 0.028). These findings suggest that placental pathophysiology and birth asphyxia may affect early and late trajectories of brain development, particularly in males with a higher vulnerability to SZ. This knowledge might lead to new strategies of treatment and prevention in SZ.

AbstractBroadly neutralizing antibodies (bnAbs) against HIV-1 target conserved envelope (Env) epitopes to block viral replication. Here, using structural analyses, we provide evidence to explain why a vaccine targeting the membrane-proximal external region (MPER) of HIV-1 elicits antibodies with human bnAb-like paratopes paradoxically unable to bind HIV-1. Unlike in natural infection, vaccination with MPER/liposomes lacks a necessary structure-based constraint to select for antibodies with an adequate approach angle. Consequently, the resulting Abs cannot physically access the MPER crawlspace on the virion surface. By studying naturally arising Abs, we further reveal that flexibility of the human IgG3 hinge mitigates the epitope inaccessibility and additionally facilitates Env spike protein crosslinking. Our results suggest that generation of IgG3 subtype class-switched B cells is a strategy for anti-MPER bnAb induction. Moreover, the findings illustrate the need to incorporate topological features of the target epitope in immunogen design.

AbstractQuantum oscillation phenomenon is an essential tool to understand the electronic structure of quantum matter. Here we report a systematic study of quantum oscillations in the electronic specific heat Cel in natural graphite. We show that the crossing of a single spin Landau level and the Fermi energy give rise to a double-peak structure, in striking contrast to the single peak expected from Lifshitz-Kosevich theory. Intriguingly, the double-peak structure is predicted by the kernel term for Cel/T in the free electron theory. The Cel/T represents a spectroscopic tuning fork of width 4.8kBT which can be tuned at will to resonance. Using a coincidence method, the double-peak structure can be used to accurately determine the Landé g-factors of quantum materials. More generally, the tuning fork can be used to reveal any peak in fermionic density of states tuned by magnetic field, such as Lifshitz transition in heavy-fermion compounds.
