Low-Performing Students Confidently Overpredict Their Grade Performance throughout the Semester.

When asked to predict how they will perform on an upcoming exam, students are often poorly calibrated, typically in the direction of overpredicting their performance. Research shows that low-performing students' calibration tends to remain poor across multiple tests over the course of a semester. We tested whether these students remain confident in these erroneously high grade predictions across the semester or whether their confidence wanes, suggesting some degree of metacognitive awareness.

N-Myc Downstream Regulated Gene-1 May Play an Important Role in the Prognosis of Ovarian Cancer, in Its Association with Beta-Catenin.

NDRG1 is a nickel- and calcium-inducible gene that plays important roles in the primary growth of malignant tumors, as well as in invasion and metastasis. This study investigated the associations of NDRG1 expression with cell adhesion and other clinicopathological factors in ovarian cancer. The clinical records of 123 women who underwent surgery for ovarian cancer in our institute were reviewed retrospectively.

Supra-second interval timing in bipolar disorder: examining the role of disorder sub-type, mood, and medication status.

Background: Widely reported by bipolar disorder (BD) patients, cognitive symptoms, including deficits in executive function, memory, attention, and timing are under-studied. Work suggests that individuals with BD show impairments in interval timing tasks, including supra-second, sub-second, and implicit motor timing compared to the neuronormative population. However, how time perception differs within individuals with BD based on disorder sub-type (BDI vs II), depressed mood, or antipsychotic medication-use has not been thoroughly investigated.

Bergson, Pan(en)theism, and 'Being-in-Life'.

Recent philosophy has witnessed a renewed interest in the works and ideas of Henri Bergson (1859-1941). But while contemporary scholarship has sought to rehabilitate Bergson's insights on time, memory, consciousness, and human freedom, comparatively little attention has been paid to Bergson's relationship to pantheism. By revisiting the 'pantheism' controversy surrounding Bergsonian philosophy during Bergson's lifetime, this article argues that the panentheistic notion of 'being-in-God' can serve as an illuminating framework for the interpretation of Bergson's philosophy.

Writing Self-Concept, Text Engagement, and Writing Practices Across Contexts: Comparisons Between School-Age Children on the Autism Spectrum and Their Non-Autistic Peers.

Purpose: Autistic children demonstrate highly variable written language skills. Existing research has focused on examining autistic children's performance on direct assessments of written language. In contrast, few studies have sought to understand how autistic children conceptualize their writing abilities or engage with writing across different contexts compared to non-autistic peers.

Neurosteroids and the mesocorticolimbic system.

The mesocorticolimbic system coordinates executive functions, such as working memory and behavioral flexibility. This circuit includes dopaminergic projections from the ventral tegmental area to the nucleus accumbens and medial prefrontal cortex. In this review, we summarize evidence that cells in multiple nodes of the mesocorticolimbic system produce neurosteroids (steroids synthesized in the nervous system) and express steroid receptors.

Predictive Factors of Negative Spillover From Caregiving to Employment Among Japanese Family Caregivers With Older Relatives in a Care Facility.

This cross-sectional study included 211 employed family caregivers with older relatives living in care facilities in Japan. Using multiple linear regression analysis, we examined the caregiving context after institutionalization of an older family member. Specifically, we examined predictors of negative spillover from caregiving to employment among family caregivers.

Maternal upbringing and selective breeding for voluntary exercise behavior modify patterns of DNA methylation and expression of genes in the mouse brain.

Selective breeding has been utilized to study the genetic basis of exercise behavior, but research suggests that epigenetic mechanisms, such as DNA methylation, also contribute to this behavior. In a previous study, we demonstrated that the brains of mice from a genetically selected high runner (HR) line have sex-specific changes in DNA methylation patterns in genes known to be genomically imprinted compared to those from a non-selected control (C) line. Through cross-fostering, we also found that maternal upbringing can modify the DNA methylation patterns of additional genes.

Competitive interference among rhizobia reduces benefits to hosts.

The capacity of beneficial microbes to compete for host infection-and the ability of hosts to discriminate among them-introduces evolutionary conflict that is predicted to destabilize mutualism. We investigated fitness outcomes in associations between legumes and their symbiotic rhizobia to characterize fitness impacts of microbial competition. Diverse Bradyrhizobium strains varying in their capacity to fix nitrogen symbiotically with a common host plant, Acmispon strigosus, were tested in full-factorial coinoculation experiments involving 28 pairwise strain combinations.

Mixoplankton and mixotrophy: future research priorities.

Phago-mixotrophy, the combination of photoautotrophy and phagotrophy in mixoplankton, organisms that can combine both trophic strategies, have gained increasing attention over the past decade. It is now recognized that a substantial number of protistan plankton species engage in phago-mixotrophy to obtain nutrients for growth and reproduction under a range of environmental conditions. Unfortunately, our current understanding of mixoplankton in aquatic systems significantly lags behind our understanding of zooplankton and phytoplankton, limiting our ability to fully comprehend the role of mixoplankton (and phago-mixotrophy) in the plankton food web and biogeochemical cycling.

Exploring tacit knowledge based on an expert nurse's practice for stroke patients.

This study explored tacit knowledge based on an expert nurse's practice who cares for stroke patients by using the hermeneutic phenomenological approach. The participant ('Ms. A') was a nursing researcher and college faculty member involved in the education of advanced practice nurses; her specialty was stroke rehabilitation nursing.

Agent-based models of the cultural evolution of occupational gender roles.

The causes of sex differences in human behaviour are contested, with 'evolutionary' and 'social' explanations often being pitted against each other in the literature. Recent work showing positive correlations between indices of gender equality and the size of sex differences in behaviour has been argued to show support for 'evolutionary' over 'social' approaches. This argument, however, neglects the potential for social learning to generate arbitrary gender segregation.

Assessing the bioactive potential of low-cost textile dyes extracted from brown seaweeds and their dyeing properties.

This study focuses on the extraction and dyeing properties of natural fabric dyes derived from brown seaweeds, namely Padina tetrastromatica, Sargassum tenerrimum, and Turbinaria ornata. Various solvents (acetone, ethanol, methanol, and water) and mordants (CH COOH, FeSO, and NaHCO) were used to extract the dyes and achieve different shades with excellent fastness properties. Phytochemical and FTIR analyses were performed to identify the phytochemicals responsible for dyeing.

Changes in social, sexual, and hedonic behaviors in rats in response to stress and restoration by a negative allosteric modulator of α5-subunit containing GABA receptor.

Major depressive disorder (MDD) is a debilitating and costly human condition. Treatment for MDD relies heavily on the use of antidepressants that are slow to produce mood-related changes and are not effective in all patients, such as selective serotonin reuptake inhibitors (SSRIs). Several novel compounds, including negative allosteric modulators of GABA-A receptors containing the α5-subunit (GABA-NAMs), are under investigation for potential fast acting therapeutic use in MDD.

Teaching and assessing undergraduate collaboration skills scaffolded through the biochemistry curriculum using collaboration rubrics and student learning contracts.

The Department of Chemistry and Biochemistry at St. Mary's College of Maryland has scaffolded collaboration skills throughout the Biochemistry curriculum and developed several assessment tools to evaluate these skills. Biochemistry I and II have used team contracts at the beginning of extensive team projects where students identify their strengths, review expectations, and plan for group communication.

Chemistry and Dynamics of Supercritical Carbon Dioxide and Methane in the Slit Pores of Layered Silicates.

ConspectusIn the mid 2010s, high-pressure diffraction and spectroscopic tools opened a window into the molecular-scale behavior of fluids under the conditions of many CO sequestration and shale/tight gas reservoirs, conditions where CO and CH are present as variably wet supercritical fluids. Integrating high-pressure spectroscopy and diffraction with molecular modeling has revealed much about the ways that supercritical CO and CH behave in reservoir components, particularly in the slit-shaped micro- and mesopores of layered silicates (phyllosilicates) abundant in caprocks and shales. This Account summarizes how supercritical CO and CH behave in the slit pores of swelling phyllosilicates as functions of the HO activity, framework structural features, and charge-balancing cation properties at 90 bar and 323 K, conditions similar to a reservoir at ∼1 km depth.

Estradiol administration increases anxiety-like behavior following chronic escalating morphine administration in hormone-replaced ovariectomized female rats.

Withdrawal from opioids can induce a state of anxiety and irritability. This negative state can facilitate continued drug taking, as the administration of opioids can alleviate unpleasant symptoms associated with acute and protracted withdrawal. It is, therefore, of interest to investigate factors that can contribute to the severity of anxiety during periods of abstinence.

Emerging carbonate anion intercalated- ZnCr-layered double hydroxide/vanadium carbide nanocomposite: A electrochemical sensor for diethofencarb fungicide monitoring.

Diethofencarb (DFC) is widely used in agriculture to fight against plant fungal attacks and enhance food crop production. On the other hand, the National food safety standard has set the overall maximum residual limit of DFC to be 1 mg/kg. Hence it becomes essential to limit their usage, and it is vital to quantify the amount of DFC present in real-life samples to safeguard the health and environmental well-being.

Deep Eutectic Solvent-Assisted Synthesis of a Strontium Tungstate Bifunctional Catalyst: Investigation on the Electrocatalytic Determination and Photocatalytic Degradation of Acetaminophen and Metformin Drugs.

In this work, we propose a modified solid-state approach for the sustainable preparation of a SrWO bifunctional catalyst using thymol-menthol-based natural deep eutectic green solvents (NADESs). Various spectroscopic and morphological techniques analyzed the as-synthesized SrWO particles. Acetaminophen (ATP) and metformin (MTF) were selected as the model drug compounds.

Unique and overlapping functions for the transcriptional regulators and in Arabidopsis gynoecium and stamen gene regulation.

Plants generate their reproductive organs, the stamens and the carpels, de novo within the flowers that form when the plant reaches maturity. The carpels comprise the female reproductive organ, the gynoecium, a complex organ that develops along several axes of polarity and is crucial for plant reproduction, fruit formation, and seed dispersal. The epigenetic trithorax group (trxG) protein ULTRAPETALA1 (ULT1) and the GARP domain transcription factor KANADI1 (KAN1) act cooperatively to regulate gynoecium patterning along the apical-basal polarity axis; however, the molecular pathways through which this patterning activity is achieved remain to be explored.
