Making the Academic Writing Process Explicit for Doctoral Students in the Social Sciences

The purpose of this article is to clarify the academic writing process and stages of publication for novice scholars. With doctoral student mentorship being highly dependent on relationships with faculty mentors, the quality and type of mentorship received varies widely. We designed this article to provide a shared starting point for new scholars trying to navigate the writing and publication process. We use our experiences as three newly tenured faculty members to provide some guidance for students. Additionally, this article adds to the existing body of knowledge on the academic writing process by bringing some hidden curriculum and norms to the forefront and making the information available to all students. Article highlights include four areas of focus of academic publishing: (a) the presentation to publication process; (b) journal choice and preparing for journal submission; (c) revision as a communal process; and (d) the journal response. Within this article, we have recommended several places where new scholars can make decisions ranging from where to submit papers, who and how to ask for help, and ways that they can respond to reviewers

Quantitative Preparation in Doctoral Education Programs: A Mixed-Methods Study of Doctoral Student Perspectives on their Quantitative Training

Aim/Purpose: The purpose of the current study is to explore student perceptions of their own doctoral-level education and quantitative proficiency. Background: The challenges of preparing doctoral students in education have been discussed in the literature, but largely from the perspective of university faculty and program administrators. The current study directly explores the student voice on this issue. Methodology: Utilizing a sequential explanatory mixed-methods research design, the present study seeks to better understand doctoral-level education students’ perceptions of their quantitative methods training at a large public university in the southwestern United States. Findings: Results from both phases present the need for more application and consistency in doctoral-level quantitative courses. Additionally, there was a consistent theme of internal motivation in the responses, suggesting students perceive their quantitative training to be valuable beyond their personal interest in the topic. Recommendations for Practitioners: Quantitative methods instructors should emphasize practice in their quantitative courses and consider providing additional support for students through the inclusion of lab sections, tutoring, and/or differentiation. Pre-testing statistical ability at the start of a course is also suggested to better meet student needs. Impact on Society: The ultimate goal of quantitative methods in doctoral education is to produce high-quality educational researchers who are prepared to apply their knowledge to problems and research in education. Results of the present study can inform faculty and administrator decisions in doctoral education to best support this goal. Future Research: Using the student perspectives presented in the present study, future researchers should continue to explore effective instructional strategies and curriculum design within education doctoral programs. The inclusion of student voice can strengthen and guide future work in this area

Extensive spontaneous plasticity of corticospinal projections after primate spinal cord injury.

Although axonal regeneration after CNS injury is limited, partial injury is frequently accompanied by extensive functional recovery. To investigate mechanisms underlying spontaneous recovery after incomplete spinal cord injury, we administered C7 spinal cord hemisections to adult rhesus monkeys and analyzed behavioral, electrophysiological and anatomical adaptations. We found marked spontaneous plasticity of corticospinal projections, with reconstitution of fully 60% of pre-lesion axon density arising from sprouting of spinal cord midline-crossing axons. This extensive anatomical recovery was associated with improvement in coordinated muscle recruitment, hand function and locomotion. These findings identify what may be the most extensive natural recovery of mammalian axonal projections after nervous system injury observed to date, highlighting an important role for primate models in translational disease research

Targeted deletion of a 170-kb cluster of LINE-1 repeats and implications for regional control.

Approximately half the mammalian genome is composed of repetitive sequences, and accumulating evidence suggests that some may have an impact on genome function. Here, we characterized a large array class of repeats of long-interspersed elements (LINE-1). Although widely distributed in mammals, locations of such arrays are species specific. Using targeted deletion, we asked whether a 170-kb LINE-1 array located at a mouse imprinted domain might function as a modulator of local transcriptional control. The LINE-1 array is lamina associated in differentiated ES cells consistent with its AT-richness, and although imprinting occurs both proximally and distally to the array, active LINE-1 transcripts within the tract are biallelically expressed. Upon deletion of the array, no perturbation of imprinting was observed, and abnormal phenotypes were not detected in maternal or paternal heterozygous or homozygous mutant mice. The array does not shield nonimprinted genes in the vicinity from local imprinting control. Reduced neural expression of protein-coding genes observed upon paternal transmission of the deletion is likely due to the removal of a brain-specific enhancer embedded within the LINE array. Our findings suggest that presence of a 170-kb LINE-1 array reflects the tolerance of the site for repeat insertion rather than an important genomic function in normal development

Implementing the battery-operated hand-held fan as an evidence-based, non-pharmacological intervention for chronic breathlessness in patients with chronic obstructive pulmonary disease (COPD): a qualitative study of the views of specialist respiratory clinicians

INTRODUCTION: The battery-operated hand-held fan ('fan') is an inexpensive and portable non-pharmacological intervention for chronic breathlessness. Evidence from randomised controlled trials suggests the fan reduces breathlessness intensity and improves physical activity in patients with a range of advanced chronic conditions. Qualitative data from these trials suggests the fan may also reduce anxiety and improve daily functioning for many patients. This study aimed to explore barriers and facilitators to the fan's implementation in specialist respiratory care as a non-pharmacological intervention for chronic breathlessness in patients with chronic obstructive pulmonary disease (COPD). METHODS: A qualitative approach was taken, using focus groups. Participants were clinicians from any discipline working in specialist respiratory care at two hospitals. Questions asked about current fan-related practice and perceptions regarding benefits, harms and mechanisms, and factors influencing its implementation. Analysis used a mixed inductive/deductive approach. RESULTS: Forty-nine participants from nursing (n = 30), medical (n = 13) and allied health (n = 6) disciplines participated across 9 focus groups. The most influential facilitator was a belief that the fan's benefits outweighed disadvantages. Clinicians' beliefs about the fan's mechanisms determined which patient sub-groups they targeted, for example anxious or palliative/end-stage patients. Barriers to implementation included a lack of clarity about whose role it was to implement the fan, what advice to provide patients, and limited access to fans in hospitals. Few clinicians implemented the fan for acute-on-chronic breathlessness or in combination with other interventions. CONCLUSION: Implementation of the fan in specialist respiratory care may require service- and clinician-level interventions to ensure it is routinely recommended as a first-line intervention for chronic breathlessness in patients for whom this symptom is of concern, regardless of COPD stage

Use of a Semi-field System to Evaluate the Efficacy of Topical Repellents under user Conditions Provides a Disease Exposure free Technique Comparable with Field Data.

Before topical repellents can be employed as interventions against arthropod bites, their efficacy must be established. Currently, laboratory or field tests, using human volunteers, are the main methods used for assessing the efficacy of topical repellents. However, laboratory tests are not representative of real life conditions under which repellents are used and field-testing potentially exposes human volunteers to disease. There is, therefore, a need to develop methods to test efficacy of repellents under real life conditions while minimizing volunteer exposure to disease. A lotion-based, 15% N, N-Diethyl-3-methylbenzamide (DEET) repellent and 15% DEET in ethanol were compared to a placebo lotion in a 200 sq m (10 m x 20 m) semi-field system (SFS) against laboratory-reared Anopheles arabiensis mosquitoes and in full field settings against wild malaria vectors and nuisance-biting mosquitoes. The average percentage protection against biting mosquitoes over four hours in the SFS and field setting was determined. A Poisson regression model was then used to determine relative risk of being bitten when wearing either of these repellents compared to the placebo. Average percentage protection of the lotion-based 15% DEET repellent after four hours of mosquito collection was 82.13% (95% CI 75.94-88.82) in the semi-field experiments and 85.10% (95% CI 78.97-91.70) in the field experiments. Average percentage protection of 15% DEET in ethanol after four hours was 71.29% (CI 61.77-82.28) in the semi-field system and 88.24% (84.45-92.20) in the field. Semi-field evaluation results were comparable to full-field evaluations, indicating that such systems could be satisfactorily used in measuring efficacy of topically applied mosquito repellents, thereby avoiding risks of exposure to mosquito-borne pathogens, associated with field testing
