Cognitive demands of face monitoring: Evidence for visuospatial overload

Young children perform difficult communication tasks better face to face than when they cannot see one another (e.g., Doherty-Sneddon & Kent, 1996). However, in recent studies, it was found that children aged 6 and 10 years, describing abstract shapes, showed evidence of face-to-face interference rather than facilitation. For some communication tasks, access to visual signals (such as facial expression and eye gaze) may hinder rather than help children’s communication. In new research we have pursued this interference effect. Five studies are described with adults and 10- and 6-year-old participants. It was found that looking at a face interfered with children’s abilities to listen to descriptions of abstract shapes. Children also performed visuospatial memory tasks worse when they looked at someone’s face prior to responding than when they looked at a visuospatial pattern or at the floor. It was concluded that performance on certain tasks was hindered by monitoring another person’s face. It is suggested that processing of visual communication signals shares certain processing resources with the processing of other visuospatial information

Perspective on Coarse-Graining, Cognitive Load, and Materials Simulation

The predictive capabilities of computational materials science today derive from overlapping advances in simulation tools, modeling techniques, and best practices. We outline this ecosystem of molecular simulations by explaining how important contributions in each of these areas have fed into each other. The combined output of these tools, techniques, and practices is the ability for researchers to advance understanding by efficiently combining simple models with powerful software. As specific examples, we show how the prediction of organic photovoltaic morphologies have improved by orders of magnitude over the last decade, and how the processing of reacting epoxy thermosets can now be investigated with million-particle models. We discuss these two materials systems and the training of materials simulators through the lens of cognitive load theory. For students, the broad view of ecosystem components should facilitate understanding how the key parts relate to each other first, followed by targeted exploration. In this way, the paper is organized in loose analogy to a coarse-grained model: The main components provide basic framing and accelerated sampling from which deeper research is better contextualized. For mentors, this paper is organized to provide a snapshot in time of the current simulation ecosystem and an on-ramp for simulation experts into the literature on pedagogical practice

Household Food Insecurity Is Associated With Diabetic Ketoacidosis but Not Severe Hypoglycemia or Glycemic Control in Youth and Young Adults With Youth‐Onset Type 2 Diabetes

Objective: To examine the association between household food insecurity (HFI), glycemic control, severe hypoglycemia and diabetic ketoacidosis (DKA) among youth and young adults (YYA) with youth-onset type 2 diabetes. Research design and methods: This cross-sectional study included 395 YYA with type 2 diabetes from the SEARCH for Diabetes in Youth Study (2015–2019). HFI was reported by young adult participants or parents of minor participants via the US Household Food Security Survey Module. Glycemic control was assessed by HbA1c and analyzed as a continuous and categorical variable (optimal:9.0%). Acute complications included self-reported severe hypoglycemia or DKA in the last 12 months. Adjusted logistic and linear regression were used for binary and continuous outcomes, respectively. Results: Approximately 31% reported HFI in the past 12 months. Mean HbA1c among those with HFI was 9.2% compared to 9.5% without HFI. Of those with HFI, 56% had an HbA1c \u3e9.0% compared to 55% without HFI. Adjusted models showed no associations between HFI and glycemic control. Of those with HFI, 14.4% reported experiencing DKA and 4.7% reported severe hypoglycemia. YYA with HFI had 3.08 times (95% CI: 1.18–8.06) the odds of experiencing DKA as those without HFI. There was no association between HFI and severe hypoglycemia. Conclusions HFI was associated with markedly increased odds of DKA but not with glycemic control or severe hypoglycemia. Future research among YYA with type 2 diabetes should evaluate longitudinally whether alleviating HFI reduces DKA

P3P: Peer-to-peer + mobile peer: API for developing P2P applications for desktop computers and mobile devices

Peer-to-Peer computing is a computing paradigm wherein computers share both information and resources with each other. Unlike server-based applications, Peer-to-Peer systems treat all nodes equally in that it allows all nodes to host information. Unfortunately, Peer-to-Peer systems are still limited to desktops, and very little support is being given to the addition of mobile devices for such systems to make it more pervasive. Given that these mobile devices are extremely portable and can increase convenience for users over a wide array of applications, it is advantageous if a study is conducted to explore the feasibility of such addition. In particular, a number of issues will have to be addressed in order to ensure that the system can overcome the limitations of such mobile devices. Availability issues will have to be addressed, due to the rather volatile connections mobile devices have, and a wider definition of information defined, since mobile devices can store information aside from typical files. These and other issues, as well as the requirements for developing such a pervasive Peer-to-Peer system, will be discussed in this paper

Suicide-related behavior and firearm access among perpetrators of domestic violence subject to domestic violence protection orders

Perpetrators of domestic violence (DV) may be a population at elevated risk of suicide. Domestic violence protection orders (DVPOs) can include the removal of firearms from the individual subjected to the order (i.e., the respondent) to protect the victim-survivor. While removal of firearms in a DVPO is designed to protect the victim-survivor; it may also prevent suicide of the respondent by reducing access to lethal means. Therefore, we examined the association of respondent suicide-related behaviors with firearm possession and weapon use in DV among a sample of granted DVPO petitions in King County, Washington (WA), United States from 2014 to 2020 (n = 2,537). We compared prevalence ratios (PR) of respondent firearm possession and use of firearms or weapons to threaten or harm by suicide-related behavior. Overall, respondent suicide-related behavior was commonly reported by petitioners (46 %). Approximately 30 % of respondents possessed firearms. This was similar between respondents with and without a history of suicide-related behavior (PR: 1.03; 95 % CI: 0.91–1.17). Respondents with a history of suicide-related behavior were 1.33 times more likely to have used firearms or weapons to threaten/harm in DV compared to those without a history of suicide-related behavior (44.1 % vs. 33.8 %; 95 % CI: 1.20–1.47). In conclusion, both firearm possession and suicide-related behaviors were common among DVPO respondents. History of suicide-related behavior may be a marker for firearm-related harm to the victim-survivor. Evaluations of DVPO firearm dispossession should consider both firearm-related injury of the victim-survivor and suicide of the respondent

Acute respiratory distress secondary to Morgagni diaphragmatic herniation in an adult.

Diaphragmatic hernias of the Morgagni type are generally thought to be asymptomatic in adults. This traditional assumption led to a delay in diagnosing a Morgagni hernia as the cause of acute respiratory distress in a chronic schizophrenic man. While Morgagni hernias are usually considered to be long-standing, we present radiological evidence of an acutely expanding hernia. The patient's symptoms were relieved by surgical repair of the hernia. We advise caution before dismissing Morgagni hernias in adults as being long-standing and clinically insignificant
