Testing Label Restrictions on Seeding Timings of Tall Fescue and Kentucky Bluegrass after Herbicide Application

During a lawn renovation, weeds are often a major problem because they grow more aggressively than seedling turf. Turfgrass seedlings need starter fertilizer and plenty of water for proper establishment, which makes an ideal environment for weeds to thrive as well. With current herbicide label restrictions, there are limited weed control strategies during the critical establishment period. Research trials were initiated in the fall of 2019 in Manhattan, KS, to determine if tall fescue (Schedonorus arundinaceus) and Kentucky bluegrass (Poa pratensis) could be seeded into a stand at different intervals after herbicide application before restrictions on the label. The results showed greater than 90% visual coverage of tall fescue seeded at 0, 3, 7, and 14 days after the application of Trimec Classic, Drive 75 DF, and SedgeHammer. Kentucky bluegrass had over 75% coverage at all seeding intervals when treated with Trimec Classic, Drive 75 DF, as well as plots seeded 3 days after the application of SedgeHammer in the Manhattan, KS, field study

Influence of Herbicides and Irrigation on Tall Fescue Shoot and Root Growth

When turfgrass stands are under renovation, a common problem is removing weeds prior to seeding because seedling turf does not emerge and compete well with weeds that are present. However, most herbicide labels recommend waiting for a defined period of time prior to seeding. If seeding is done prior to the date prescribed on the herbicide label, seed germination and seedling growth may be inhibited. A greenhouse study was conducted to determine the effects of irrigation prior to seeding on seedling growth after herbicide application. Overall, irrigation had no influence on the impact of herbicides on shoot or root growth in these greenhouse experiments. Our results suggest delaying seeding by more than 3 days after the application of 2,4-D + MCPP + dicamba (Trimec Classic) may not be necessary

Tall Fescue Seedling Growth as Affected by Postemergence Herbicides

The objective of this greenhouse study was to evaluate tall fescue (Festuca arundinacea) seedling growth when seeded after herbicide application. Herbicide treatments included a nontreated control; 1.19 lb/acre 2,4-dichlorophenoxyacetic acid (2,4-D) + 0.32 lb/acre methylchlorophenoxypropionic acid (MCPP) + 0.32 lb/acre dicamba; 0.75 lb/acre quinclorac; and 0.06 lb/acre halosulfuron-methyl. Seeding was done at 0, 3, 7, or 14 days after herbicide application to soil media. Two identical experiments were conducted in the greenhouse: Expt. 1 seedling growth from January to March and Expt. 2 from May to July (temperatures higher). Seeding dates after herbicide application did not influence growth. Average dry shoot weight reductions and dry root weight reductions caused by postemergence herbicides were 2,4-D + MCPP + dicamba (33% shoot and 27% root in Expt. 2), quinclorac (30% shoot and 37% root in Expt. 2), and halosulfuron-methyl (51% shoot in Expt. 2; 81% root in Expts. 1 and 2). Although application of these herbicides before seeding in the field may result in no visual impact, they can impact seedling shoot and root growth, particularly under higher growth temperatures

Teacher behavior checklist: psychometric evidence in teacher evaluation by Brazilian university students

Performance evaluations help university teachers to improve teaching, especially when based on internationally recognized criteria. This study aimed to carry out a cross-cultural adaptation of the Teacher Behavior Checklist (TBC) for Brazilian students to evaluate their teachers (Study 1) and investigate its psychometric evidence (Study 2). In Study 1, evidence was favorable to the use of TBC for teacher evaluation by the student. In Study 2, 714 public university students participated (Average age = 24.3 years; SD = 6.85), 57.2% women. The TBC was applied collectively in the classroom. The results corroborated the two-factor model according to the instrument’s original version, demonstrating an evidence of validity. Evidence of reliability has been documented (alpha = 0.92; Test-Retest = 0.75). This study presented an adequate instrument for the teacher formative evaluation and expanded Brazil’s insertion in international research on effective teaching.Las evaluaciones de desempeño ayudan a que los docentes universitarios mejoren la enseñanza, sobre todo cuando se basan en criterios reconocidos internacionalmente.

Clinical decisions and stigmatizing attitudes towards mental health problems in primary care physicians from Latin American countries

Objective The aim of this paper is to investigate how doctors working in primary health care in Latin American address patients with common mental disorders and to investigate how stigma can affect their clinical decisions. Methods Using a cross-sectional design, we applied an online self-administered questionnaire to a sample of 550 Primary Care Physicians (PCPs) from Bolivia, Brazil, Cuba and Chile. The questionnaire collected information about sociodemographic variables, training and experience with mental health care. Clinicians’ stigmatizing attitudes towards mental health were measured using the Mental Illness Clinicians' Attitudes Scale (MICA v4). The clinical decisions of PCPs were assessed through three clinical vignettes representing typical cases of depression, anxiety and somatization. Results A total of 387 professionals completed the questionnaires (70.3% response rate). The 63.7% of the PCPs felt qualified to diagnose and treat people with common mental disorders. More than 90% of the PCPs from Bolivia, Cuba and Chile agreed to treat the patients presented in the three vignettes. We did not find significant differences between the four countries in the scores of the MICA v4 stigma levels, with a mean = 36.3 and SD = 8.3 for all four countries. Gender (p = .672), age (p = .171), training (p = .673) and years of experience (p = .28) were unrelated to stigma. In the two multivariate regression models, PCPs with high levels of stigma were more likely to refer them to a psychiatrist the patients with depression (OR = 1.03, 95% CI, 0.99 to 1.07 p<0.05) and somatoform symptoms somatoform (OR = 1.03, 95% CI, 1.00 to 1.07, p<0.05) to a psychiatrist. Discussion The majority of PCPs in the four countries were inclined to treat patients with depression, anxiety and somatoform symptoms. PCPs with more levels of stigma were more likely to refer the patients with depression and somatoform symptoms to a psychiatrist. Stigmatizing attitudes towards mental disorders by PCPs might be important barriers for people with mental health problems to receive the treatment they need in primary care

The purpose of the study was to analyze the performance of the World Health Organization (WHO) Field Studies Coordination Group (FSCG) using an input-processes-output (IPO) team science model to better understand the team's challenges, limitations, and successes in developing the eleventh revision of the International Classification of Diseases (ICD). Method: We thematically analyzed a collection of written texts, including FSCG documents and open-ended qualitative questionnaires, according to the conceptualization of the input-processes-output model of team performance. Results: The FSCG leadership and its members experienced and overcame numerous barriers to become an effective international team and to successfully achieve the goals set forth by WHO. Conclusions: Research is necessary regarding global mental health collaboration to understand and facilitate international collaborations with the goal of contributing to a deeper understanding of mental health and to reduce the global burden of mental disorders around the world

Mental health professionals' use of the ICD-11 classification of impulse control disorders and behavioral addictions: An international field study

Background and aims The ICD-11 chapter on mental, behavioral and neurodevelopmental disorders contains new controversial diagnoses including compulsive sexual behavior disorder (CSBD), intermittent explosive disorder (IED) and gaming disorder. Using a vignette-based methodology, this field study examined the ability of mental health professionals (MHPs) to apply the new ICD-11 diagnostic requirements for impulse control disorders, which include CSBD and IED, and disorders due to addictive behaviors, which include gaming disorder, compared to the previous ICD-10 guidelines. Methods Across eleven comparisons, members of the WHO's Global Clinical Practice Network (N = 1,090) evaluated standardized case descriptions that were designed to test key differences between the diagnostic guidelines of ICD-11 and ICD-10. Results The ICD-11 outperformed the ICD-10 in the accuracy of diagnosing impulse control disorders and behavioral addictions in most comparisons, while the ICD-10 was not superior in any. The superiority of the ICD-11 was particularly clear where new diagnoses had been added to the classification system or major revisions had been made. However, the ICD-11 outperformed the ICD-10 only in a minority of comparisons in which mental health professionals were asked to evaluate cases with non-pathological high involvement in rewarding behaviors. Discussion and Conclusions Overall, the present study indicates that the ICD-11 diagnostic requirements represent an improvement over the ICD-10 guidelines. However, additional efforts, such as training programs for MHPs and possible refinements of diagnostic guidance, are needed to avoid over-diagnosis of people who are highly engaged in a repetitive and rewarding behavior but below the threshold for a disorder

Validez de las categorías relacionadas con la identidad de genero en la CIE-11 y el DSM-5 entre personas transgenero que buscan procedimientos medicos que afirmen su genero

BACKGROUND/OBJECTIVE : The most recent versions of the two main mental disorders classifications-the World Health Organization's ICD-11 and the American Psychiatric Association's DSM-5-differ substantially in their diagnostic categories related to transgender identity. ICD-11 gender incongruence (GI), in contrast to DSM-5 gender dysphoria (GD), is explicitly not a mental disorder; neither distress nor dysfunction is a required feature. The objective was compared ICD-11 and DSM-5 diagnostic requirements in terms of their sensitivity, specificity, discriminability and ability to predict the use of gender-affirming medical procedures. METHOD : A total of 649 of transgender adults in six countries completed a retrospective structured interview. RESULTS : Using ROC analysis, sensitivity of the diagnostic requirements was equivalent for both systems, but ICD-11 showed greater specificity than DSM-5. Regression analyses indicated that history of hormones and/or surgery was predicted by variables that are an intrinsic aspect of GI/GD more than by distress and dysfunction. IRT analyses showed that the ICD-11 diagnostic formulation was more parsimonious and contained more information about caseness than the DSM-5 model. CONCLUSIONS : This study supports the ICD-11 position that GI/GD is not a mental disorder; additional diagnostic requirements of distress and/or dysfunction in DSM-5 reduce the predictive power of the diagnostic model.Partially funded by unrestricted grants by the World Health Organization Department of Mental Health and Substance Abuse to participating institutions in Brazil, India, Lebanon, Mexico, and South Africa for the development and implementation of ICD-11 field studies.
