    Expectation Versus Reality: Perceived Differences in Cognitive Ability Between Men and Women

    Get PDF
    In Western society, there is a common belief that there are clear differences between male and female brains. In our project, we hope to gain insight into the beliefs of undergraduate students regarding this very idea. We are surveying Binghamton University students about their perceptions regarding the differences in cognitive ability between cis-gender men and women. Our survey asks students if certain skills are gendered, which gender these skills are more closely associated with, and where students learned these stereotypes. These results will be compared to the current state of knowledge about cognitive differences between the sexes. We anticipate that students will overestimate the extent of brain differences between the sexes, as our culture has conditioned us to believe. Our goal is to enlighten others about the pervasiveness of neurosexism.https://orb.binghamton.edu/research_days_posters_2022/1097/thumbnail.jp

    BACKGROUND: Understanding links between behaviour change techniques (BCTs) and mechanisms of action (the processes through which they affect behaviour) helps inform the systematic development of behaviour change interventions. PURPOSE: This research aims to develop and test a methodology for linking BCTs to their mechanisms of action. METHODS: Study 1 (published explicit links): Hypothesised links between 93 BCTs (from the 93-item BCT taxonomy, BCTTv1) and mechanisms of action will be identified from published interventions and their frequency, explicitness and precision documented. Study 2 (expert-agreed explicit links): Behaviour change experts will identify links between 61 BCTs and 26 mechanisms of action in a formal consensus study. Study 3 (integrated matrix of explicit links): Agreement between studies 1 and 2 will be evaluated and a new group of experts will discuss discrepancies. An integrated matrix of BCT-mechanism of action links, annotated to indicate strength of evidence, will be generated. Study 4 (published implicit links): To determine whether groups of co-occurring BCTs can be linked to theories, we will identify groups of BCTs that are used together from the study 1 literature. A consensus exercise will be used to rate strength of links between groups of BCT and theories. CONCLUSIONS: A formal methodology for linking BCTs to their hypothesised mechanisms of action can contribute to the development and evaluation of behaviour change interventions. This research is a step towards developing a behaviour change 'ontology', specifying relations between BCTs, mechanisms of action, modes of delivery, populations, settings and types of behaviour.Medical Research Council (Grant ID: MR/L011115/1)This is the final version of the article.

    Circulating resistin levels and risk of multiple myeloma in three prospective cohorts

    Get PDF
    BACKGROUND: Resistin is a polypeptide hormone secreted by adipose tissue. A prior hospital-based case-control study reported serum resistin levels to be inversely associated with risk of multiple myeloma (MM). To date, this association has not been investigated prospectively. METHODS: We measured resistin concentrations for pre-diagnosis peripheral blood samples from 178 MM cases and 358 individually matched controls from three cohorts participating in the MM cohort consortium. RESULTS: In overall analyses, higher resistin levels were weakly associated with reduced MM risk. For men, we observed a statistically significant inverse association between resistin levels and MM (odds ratio, 0.44; 95% confidence interval (CI) 0.24-0.83 and 0.54; 95% CI 0.29-0.99, for the third and fourth quartiles, respectively, vs the lowest quartile; Ptrend=0.03). No association was observed for women. CONCLUSIONS: This study provides the first prospective evidence that low circulating resistin levels may be associated with an increased risk of MM, particularly for men

    Dietary cadmium intake and fecundability in a North American preconception cohort study

    Objective To evaluate the association between dietary cadmium intake (D-Cd) and fecundability. Diet is one of the main sources of cadmium, and D-Cd is often used as indicator of cadmium exposure, particularly in non-smoking populations. In a previous preconception cohort study of 501 couples,1 high female cadmium concentrations measured in whole blood were associated with reduced fecundability. Design Prospective cohort study (2013-2018). Materials and Methods Pregnancy Online Study (PRESTO) is a North American prospective preconception cohort of pregnancy planners. At baseline, female participants aged 21-45 years completed a web-based questionnaire on demographic, lifestyle, medical and reproductive factors. Ten days after enrollment, participants completed the National Cancer Institute Dietary History Questionnaire II, a validated food frequency questionnaire (FFQ) of average intake during the previous year. D-Cd (\u3bcg/day) was estimated by combining FFQ responses with US Food and Drug Administration data on food cadmium content. Participants were then followed for up to 12 months or until reported pregnancy, whichever came first. The analysis included 4,768 women attempting to conceive for 646 cycles at study entry and not using fertility treatment. We used a proportional probabilities regression model to estimate fecundability ratios (FR) and 95% confidence intervals (CI), adjusted for age, body mass index (BMI), smoking history, parity, physical activity, last method of contraception, daily use of multivitamins, race/ethnicity, education, income, geographic region, and the 2010 healthy eating index score. We used the nutrient residual approach to adjust for energy intake. Results Median D-Cd was 8.0 \u3bcg/day (interquartile range: 7.0-9.1 \u3bcg/day). The top 5 contributors to D-Cd were nuts and seeds; fried potatoes; dark green lettuce; cooked greens; and white potatoes. Compared with an average D-Cd of <6.8 \u3bcg/day, FRs for D-Cd quintiles of 6.8-7.6, 7.7-8.4, 8.5-9.5, and 659.6 \u3bcg/day were 1.03 (CI: 0.92-1.14), 1.07 (CI: 0.96-1.18), 1.07 (CI: 0.96-1.19), and 1.08 (0.97-1.20), respectively. Results were not appreciably different among never smokers with no current passive smoke exposure, for whom cadmium exposure from other sources (e.g., cigarettes) would be lower (respective FRs: 1.02, 1.05, 1.06 and 1.02). Results did not differ materially by age (<30 vs. 6530 years), BMI (<30 vs. 6530 kg/m2), total fiber intake (<25 vs. 6525 g/day), geographic region of residence (West, Midwest, Northeast, South, Canada), or attempt time at study entry (<3 vs. 653 cycles). Conclusions Dietary intake of cadmium was not appreciably associated with fecundability, though exposure misclassification and confounding could explain the null results.

    Developing an evidence-based online method of linking behaviour change techniques and theoretical mechanisms of action: a multiple methods study

    Get PDF
    Background: Many global health challenges may be targeted by changing people’s behaviour. Behaviours including cigarette smoking, physical inactivity and alcohol misuse, as well as certain dietary behaviours, contribute to deaths and disability by increasing the risk of cancers, cardiovascular diseases and diabetes. Interventions have been designed to change these health behaviours with a view to reducing these health risks. However, the effectiveness of these interventions has been quite variable and further information is needed to enhance their success. More information is needed about the specific processes that underlie the effectiveness of intervention strategies. Aim: Researchers have developed a taxonomy of 93 behaviour change techniques (i.e. the active components of an intervention that bring about behavioural change), but little is known regarding their potential mechanisms of action (i.e. the processes through which a behaviour change technique affects behaviour).We therefore aimed to examine links between behaviour change techniques and mechanisms of action. Method: First, we conducted a literature synthesis study of 277 behaviour change intervention studies, from which we extracted information on links, described by authors, between behaviour change techniques and mechanisms of action, and identified an average of 10 links per intervention report. Second, behaviour change experts (n = 105) were engaged in a three-round consensus study in which they discussed and rated their confidence in the presence/absence of ‘links’ and ‘non-links’ between commonly used behaviour change techniques (n = 61) and a set of mechanisms of action (n = 26). Ninety links and 460 ‘non-links’ reached the pre-set threshold of 80% agreement. To enhance the validity of these results, a third study was conducted that triangulated the findings of the first two studies. Discrepancies and uncertainties between the studies were included in a reconciliation consensus study with a new group of experts (n = 25). The final results identified 92 definite behaviour change technique–mechanism of action links and 465 definite non-links. In a fourth study, we examined whether or not groups of behaviour change techniques used together frequently across interventions revealed shared theoretical underpinnings. We found that experts agreed on the underlying theory for three groups of behaviour change techniques. Results: Our results are potentially useful to policy-makers and practitioners in selecting behaviour change techniques to include in behaviour change interventions. However, our data do not demonstrate that the behaviour change techniques are effective in targeting the mechanism of action; rather, the links identified may be the ‘best bets’ for interventions that are effective in changing mechanisms of action, and the non-links are unlikely to be effective. Researchers examining effectiveness of interventions in either primary studies or evidence syntheses may consider these links for further investigation. Conclusion: To make our results usable by researchers, practitioners and policy-makers, they are available in an online interactive tool, which enables discussion and collaboration (https://theoryandtechniquetool. humanbehaviourchange.org/); accessed 1 March 2020. This work, building on previous work to develop the behaviour change technique taxonomy, is part of an ongoing programme of work: the Human Behaviour Change Project (www.humanbehaviourchange.org/; accessed 1 March 2020).

    Greywater Implementation in Montgomery County

    Final project for ENSP400: Capstone in Environmental Science and Policy (Fall 2017). University of Maryland, College Park.The Montgomery County Parks Department needs to adopt an alternative water source to secure the future of their water supply at their Damascus and Cabin John facilities. A greywater system is a viable option. Greywater is a sustainable, innovative water source collected from sinks and ice shavings for reuse options, conserving water, and reducing energy. Construction and design of these facilities will require new and retrofit strategies. As greywater contributes to a significant percentage of wastewater in public areas, including parks and ice rinks, a proper treatment system is required to remove bacteria and organic compounds. One such system is the Aqua2use Greywater Treatment System, which is a storage and sanitation system that is appropriate for non-potable water reuse and is economically beneficial. This document provides the blueprints, permits, costs, and the distribution and treatment processes for a greywater system for new and retrofit facilities. Case studies conducted at the Lee Valley facility in England and the Citizen Bank Arena in Ontario, California will aid in determining the design and construction of the greywater ice rink system. Studying the implementation of a greywater system in Spain will help determine the organization of a new or retrofit system. Quantitative assessments of water usage from toilets and ice rinks at the Cabin John facility, accompanied by indirect expense reductions that a greywater system generates, will aid in determining implementation costs. These systems will also comply with the plumbing code of Maryland, EPA’s 2012 water reuse guidelines, and the 2011 NSF/ANSI 350 for design, operation, and monitoring requirements. This paper aims to propose a system that provides alternate reuse options projecting at least a 30 percent reduction in water consumption. This result came from the Rockville 2017 Water Quality Report, which concluded that the use of an alternate toilet-flushing program resulted in a 40 percent decrease in water consumption when using an alternate non-potable water source.Montgomery Count

    Liquid–liquid phase separation of the Golgi matrix protein GM130

    Get PDF
    Golgins are an abundant class of peripheral membrane proteins of the Golgi. These very long (50–400 nm) rod-like proteins initially capture cognate transport vesicles, thus enabling subsequent SNARE-mediated membrane fusion. Here, we explore the hypothesis that in addition to serving as vesicle tethers, Golgins may also possess the capacity to phase separate and, thereby, contribute to the internal organization of the Golgi. GM130 is the most abundant Golgin at the cis Golgi. Remarkably, overexpressed GM130 forms liquid droplets in cells analogous to those described for numerous intrinsically disordered proteins with low complexity sequences, even though GM130 is neither low in complexity nor intrinsically disordered. Virtually pure recombinant GM130 also phase-separates into dynamic, liquid-like droplets in close to physiological buffers and at concentrations similar to its estimated local concentration at the cis Golgi

    Do Combinations of Behavior Change Techniques That Occur Frequently in Interventions Reflect Underlying Theory?

    Get PDF
    BACKGROUND: Behavioral interventions typically include multiple behavior change techniques (BCTs). The theory informing the selection of BCTs for an intervention may be stated explicitly or remain unreported, thus impeding the identification of links between theory and behavior change outcomes. PURPOSE: This study aimed to identify groups of BCTs commonly occurring together in behavior change interventions and examine whether behavior change theories underlying these groups could be identified. METHODS: The study involved three phases: (a) a factor analysis to identify groups of co-occurring BCTs from 277 behavior change intervention reports; (b) examining expert consensus (n = 25) about links between BCT groups and behavioral theories; (c) a comparison of the expert-linked theories with theories explicitly mentioned by authors of the 277 intervention reports. RESULTS: Five groups of co-occurring BCTs (range: 3-13 BCTs per group) were identified through factor analysis. Experts agreed on five links (≄80% of experts), comprising three BCT groups and five behavior change theories. Four of the five BCT group-theory links agreed by experts were also stated by study authors in intervention reports using similar groups of BCTs. CONCLUSIONS: It is possible to identify groups of BCTs frequently used together in interventions. Experts made shared inferences about behavior change theory underlying these BCT groups, suggesting that it may be possible to propose a theoretical basis for interventions where authors do not explicitly put forward a theory. These results advance our understanding of theory use in multicomponent interventions and build the evidence base for further understanding theory-based intervention development and evaluation

    Development of an online tool for linking behavior change techniques and mechanisms of action based on triangulation of findings from literature synthesis and expert consensus.

    Researchers, practitioners, and policymakers develop interventions to change behavior based on their understanding of how behavior change techniques (BCTs) impact the determinants of behavior. A transparent, systematic, and accessible method of linking BCTs with the processes through which they change behavior (i.e., their mechanisms of action [MoAs]) would advance the understanding of intervention effects and improve theory and intervention development. The purpose of this study is to triangulate evidence for hypothesized BCT-MoA links obtained in two previous studies and present the results in an interactive, online tool. Two previous studies generated evidence on links between 56 BCTs and 26 MoAs based on their frequency in literature synthesis and on expert consensus. Concordance between the findings of the two studies was examined using multilevel modeling. Uncertainties and differences between the two studies were reconciled by 16 behavior change experts using consensus development methods. The resulting evidence was used to generate an online tool. The two studies showed concordance for 25 of the 26 MoAs and agreement for 37 links and for 460 "nonlinks." A further 55 links were resolved by consensus (total of 92 [37 + 55] hypothesized BCT-MoA links). Full data on 1,456 possible links was incorporated into the online interactive Theory and Technique Tool (https://theoryandtechniquetool.humanbehaviourchange.org/). This triangulation of two distinct sources of evidence provides guidance on how BCTs may affect the mechanisms that change behavior and is available as a resource for behavior change intervention designers, researchers and theorists, supporting intervention design, research synthesis, and collaborative research.MR

    The Building Blocks of Interoperability. A Multisite Analysis of Patient Demographic Attributes Available for Matching.

    BackgroundPatient matching is a key barrier to achieving interoperability. Patient demographic elements must be consistently collected over time and region to be valuable elements for patient matching.ObjectivesWe sought to determine what patient demographic attributes are collected at multiple institutions in the United States and see how their availability changes over time and across clinical sites.MethodsWe compiled a list of 36 demographic elements that stakeholders previously identified as essential patient demographic attributes that should be collected for the purpose of linking patient records. We studied a convenience sample of 9 health care systems from geographically distinct sites around the country. We identified changes in the availability of individual patient demographic attributes over time and across clinical sites.ResultsSeveral attributes were consistently available over the study period (2005-2014) including last name (99.96%), first name (99.95%), date of birth (98.82%), gender/sex (99.73%), postal code (94.71%), and full street address (94.65%). Other attributes changed significantly from 2005-2014: Social security number (SSN) availability declined from 83.3% to 50.44% (p<0.0001). Email address availability increased from 8.94% up to 54% availability (p<0.0001). Work phone number increased from 20.61% to 52.33% (p<0.0001).ConclusionsOverall, first name, last name, date of birth, gender/sex and address were widely collected across institutional sites and over time. Availability of emerging attributes such as email and phone numbers are increasing while SSN use is declining. Understanding the relative availability of patient attributes can inform strategies for optimal matching in healthcare
