Am I Able to Predict How I Will Do? Examining Calibration in an Undergraduate Biology Course

Students who are self-regulated are more likely to succeed academically, whereas students who have deficiencies in their learning have been recognized as having a lack of metacognitive awareness (Valdez, 2013; Zimmerman, 2002). If students are metacognitively unaware in large introductory courses, they may have difficulty knowing when to self-regulate and modify their learning (Lin & Zabrucky, 1998; Stone, 2000). One manner in which researchers have assessed students’ metacognitive awareness is by asking students to estimate how they think they will do on tasks compared to their actual performance, known as calibration. The purpose of this study was to examine students’ calibration and study habits. Participants were undergraduates (N = 384) in an introductory biology course at a southeastern U.S. university. Students completed four surveys that assessed their exam score expectations and the study habits they used prior to each exam. Results showed that students’ estimates are most discrepant from their actual performance early in the semester and become more accurate at the end of the semester. A closer look at students’ study habits revealed that the inaccuracy of students’ exam judgments showed little connection to the study strategies that students used. Findings from this study are important for biology instructors

Seeing red : the Mackenzie-Papineau Battalion in Canadian history and memory

124 leaves : colour illustrations ; 29 cmIncludes abstract and appendices.Includes bibliographical references (leaves 117-124).The Mackenzie-Papineau Battalion are a group that has been historically overlooked. Since they first volunteered to fight in the Spanish Civil War there has been a stigma associated with this group, a taint of communism that made them ‘suspect’. This negative association led to increased attention from the RCMP and ultimately the denial of veteran status from the federal government. This study explores the way in which these volunteers have been viewed since their enlistment and return to Canada and how these views have shaped the memory, or lack thereof, of the Mackenzie-Papineau Battalion

Potential Effects of an Invasive Nitrogen-Fixing Tree on a Hawaiian Stream Food Web.

v. ill. 23 cm.QuarterlyFalcataria moluccana (albizia) is an exotic nitrogen (N)-fixing tree currently invading riparian forests in Hawai‘i, U.S.A. This study examined how this invasion is impacting stream ecosystems by using naturally occurring stable isotopes of carbon (C) and N to compare food web structure between a noninvaded and an albizia-invaded stream reach on the island of Hawai‘i. Isotopic signatures of particulate organic matter (POM), macroalgae, invertebrates, and fishes were collected and compared between the two stream reaches. Stable C isotopic signatures of organic matter sources (POM and macroalgae) and consumers (amphipods, caddisflies, crayfish, and fishes) from the invaded site were depleted in 13C compared with the noninvaded site. In contrast, all samples from the invaded site were enriched in 15N compared with the noninvaded site. Results from IsoSource and two-source mixing models suggested that albizia was a major contributor to diets of lower-level consumers within the invaded site, displacing POM and macroalgae as their major food sources. Albizia was also an indirect C and N source for higher-level consumers within the invaded site because albizia was the major dietary constituent of their prey. In addition, 15N enrichment of the macroalgae at the invaded site suggests that albizia may be an important N source to benthic primary producers and could be further altering the food web from bottom up. Our study provides some of the first evidence that invasive riparian N-fixing trees can potentially alter the structure of stream food webs

Feasibility randomised multicentre, double-blind, double-dummy controlled trial of anakinra, an interleukin-1 receptor antagonist versus intramuscular methylprednisolone for acute gout attacks in patients with chronic kidney disease (ASGARD): protocol study

Introduction: Acute gout occurs in people with chronic kidney disease, who are commonly older people with comorbidities such as hypertension, heart disease and diabetes. Potentially harmful treatments are administered to these vulnerable patients due to a lack of clear evidence. Newly available treatment that targets a key inflammatory pathway in acute gout attacks provides an opportunity to undertake the first-ever trial specifically looking treating people with kidney disease. This paper describes the protocol for a feasibility randomised controlled trial (RCT) comparing anakinra, a novel interleukin-1 antagonist versus steroids in people with chronic kidney disease (ASGARD). Methods and analysis: ASGARD is a two-parallel group double-blind, double-dummy multicentre RCT comparing anakinra 100 mg, an interleukin-1 antagonist, subcutaneous for 5 days against intramuscular methylprednisolone 120 mg. The primary objective is to assess the feasibility of the trial design and procedures for a definitive RCT. The specific aims are: (1) test recruitment and retention rates and willingness to be randomised; (2) test eligibility criteria; (3) collect and analyse outcome data to inform sample and power calculations for a trial of efficacy; (4) collect economic data to inform a future economic evaluation estimating costs of treatment and (5) assess capacity of the project to scale up to a national multicentre trial. We will also gather qualitative insights from participants. It aims to recruit 32 patients with a 1:1 randomisation. Information from this feasibility study will help design a definitive trial and provide general information in designing acute gout studies. Ethics and dissemination: The London-Central Ethics Committee approved the protocol. The results will be disseminated in peer-reviewed journals and at scientific conferences

Questing behavior and analysis of tick-borne bacteria in Ixodes scapularis (Acari: Ixodidae) in Oklahoma

The blacklegged tick, Ixodes scapularis Say (Acari: Ixodidae), is an economically important tick that affects veterinary and public health, but it can be difficult to collect in Oklahoma. The primary goal of this research was to examine the diel activity of each species to help improve collection methods for future field research and test field-collected I. scapularis for endemic and nonendemic tick-borne bacterial genera in the southern Great Plains region. Questing behavior was observed using caged bioassays over 24-h periods throughout fall and spring, and field collections were conducted throughout the afternoon and evening in different locations across Oklahoma. Blacklegged ticks were found to be more active during late afternoon and evening hours, and more ticks were recovered in pastures in the evening. None of the pools of adult I. scapularis tested positive for Borrelia burgdorferi (Spirochaetales: Spirochaetaceae) or Anaplasma phagocytophilum (Rickettsiales: Anaplasmataceae) DNA. Of the 46 pools of I. scapularis tested, 27 (58.7%) were positive for Rickettsia sp. with ticks collected from the same location infected with the same species of rickettsial endosymbionts. Results suggest that sampling times later in the day may benefit off-host recovery of I. scapularis in Oklahoma ecosystems.Peer reviewedEntomology and Plant Patholog

Exercise is medicine in oncology: Engaging clinicians to help patients move through cancer

A compelling evidence base supports exercise as a safe, effective intervention to improve many cancer related health outcomes among cancer patients and survivors. Oncology clinicians play a key role in encouraging their patients to move more. Therefore, the oncology clinical care team is urged to do the following at regular intervals: ASSESS exercise levels, ADVISE patients to become more active, and REFER patients to specific exercise programming. It is recommended that a process be developed to incorporate these steps into the standard care of oncology patients. A simple, straightforward approach is recommended to discern whether patients should be referred to outpatient rehabilitation versus community based exercise programming. The exponential growth of exercise oncology research has driven the need for revised cancer exercise guidelines and a roadmap for oncology clinicians to follow to improve physical and psychological outcomes from cancer diagnosis and for the balance of life. This paper serves as a call to action and details pathways for exercise programming (clinical, community and self-directed) tailored to the different levels of support and intervention needed by a given cancer patient or survivor. Preserving activity and functional ability is integral to cancer care and oncology clinicians are key to providing these referrals
