Metabolic Resistance to Protoporphyrinogen Oxidase-Inhibitor Herbicides in a Palmer amaranth Population from Kansas.

Palmer amaranth has evolved target and nontarget site resistance to protoporphyrinogen oxidase-inhibitor herbicides in the United States. Recently, a population (KCTR) from a long-term conservation tillage study in Kansas was found to be resistant to herbicides from six sites of action, including to PPO-inhibitors, even with this herbicide group being minimally used in this field. This research investigated the level of resistance to postemergence PPO-inhibitors, target- and nontarget-site resistance mechanism(s), and efficacy of pre-emergence chemistries.

Evaluating the Efficacy of a Narrative Language Intervention for Bilingual Students.

Purpose: This study examines the narrative language and reading outcomes of monolingual and bilingual students who received instruction with the Supporting Knowledge in Language and Literacy (SKILL) program, a narrative language intervention.

Method: The main effects of the SKILL program were evaluated in a randomized controlled trial in which students ( = 355) who were at risk for English language and literacy difficulties were randomized to the SKILL intervention or a business-as-usual instruction. This article reports secondary analyses examining the efficacy of SKILL for bilingual ( = 148) and monolingual ( = 207) students who completed measures of oral and written narrative language and reading comprehension in English.

Perioperative Operating Room Efficiency Can Make Simultaneous Bilateral Total Hip Arthroplasty Cost-effective: A Proposal for a Value-sharing Model.

Background: Increasing demand for total hip arthroplasty (THA) and rising health-care costs have led hospitals to improve operating room (OR) efficiency. We compare the cost-effectiveness of a simultaneous bilateral THA to that of staged unilateral procedures following the implementation of OR efficiency strategies.

Methods: Between 2017 and 2019, 446 simultaneous and 238 staged bilateral primary THA patients (mean age 61.

A meta-analysis of the effects of academic interventions on academic achievement and academic anxiety outcomes in elementary school children.

Research has shown that academic anxiety can affect academic performance and emotional well-being. Despite previous research emphasizing the importance of understanding academic anxiety and indicating a strong association between academic performance and academic anxiety, no systematic reviews or meta-analyses have examined the effects of academic interventions on academic and anxiety outcomes. This article reports on a meta-analysis of studies examining academic interventions conducted with elementary students (kindergarten to Grade 6), in which both academic achievement and academic anxiety outcomes were reported.

Understanding the nature and severity of reading difficulties among students with language and reading comprehension difficulties.

This study investigated the presence of word reading difficulties in a sample of students in Grades 1-4 (n = 357) identified with language and reading comprehension difficulties. This study also examined whether distinct word reading and listening comprehension profiles emerged within this sample and the extent to which these groups varied in performance on cognitive and demographic variables. Findings showed that the majority of students (51%) with language and reading comprehension difficulties demonstrated significant risk in word reading (more than 1 SD below the mean), even though the participant screening procedures did not examine word reading directly.
