Protocol for a systematic review on the extent of non-publication of research studies and associated study characteristics
Portalupi Susan,von Elm Erik,Schmucker Christine,Lang Britta
Systematic Reviews , 2013, DOI: 10.1186/2046-4053-2-2
Abstract: Background Methodological research has found that non-published studies often have different results than those that are published, a phenomenon known as publication bias. When results are not published, or are published selectively based on the direction or the strength of the findings, healthcare professionals and consumers of healthcare cannot base their decision-making on the full body of current evidence. Methods As part of the OPEN project (http://www.open-project.eu) we will conduct a systematic review with the following objectives: 1. To determine the proportion and/or rate of non-publication of studies by systematically reviewing methodological research projects that followed up a cohort of studies that a. received research ethics committee (REC) approval, b. were registered in trial registries, or c. were presented as abstracts at conferences. 2. To assess the association of study characteristics (for example, direction and/or strength of findings) with likelihood of full publication. To identify reports of relevant methodological research projects we will conduct electronic database searches, check reference lists, and contact experts. Published and unpublished projects will be included. The inclusion criteria are as follows: a. RECs: methodological research projects that examined the subsequent proportion and/or rate of publication of studies that received approval from RECs; b. Trial registries: methodological research projects that examine the subsequent proportion and/or rate of publication of studies registered in trial registries; c. Conference abstracts: methodological research projects that examine the subsequent proportion and/or rate of full publication of studies which were initially presented at conferences as abstracts. Primary outcomes: Proportion/rate of published studies; time to full publication (mean/median; cumulative publication rate by time). Secondary outcomes: Association of study characteristics with full publication. The different questions (a, b, and c) will be investigated separately. Data synthesis will involve a combination of descriptive and statistical summaries of the included methodological research projects. Discussion Results are expected to be publicly available in mid 2013.

Abstract: this research was carried out in 17 municipalities of the state of parana, brazil, with population up to 250 thousand inhabitants. the municipalities were chosen based on peculiar characteristics of six different regions of the state. the development of the field research was carried out through data collection of physiographic and environmental, socio-economical and structural aspects of each community. this research also considered administrative, operational and social aspects with the aim to develop a data base model for the systematization of municipal solid waste programmes and services. the resulting data base facilitated both the diagnosis and the visualization of all system input information. it is worth mentioning that the results produced by this research can be used as a managerial tool for decision makers at municipal and state levels with regard to integrated solid waste programmes.
Is Distance Education the Answer to the Nursing Shortage?  [PDF]
Susan Mee
Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.43020
Abstract:

This study examined the effectiveness of distance education compared with campus based learning among nursing students. Distance education in nursing curricula is increasing. Academic nurse leaders must demonstrate the effectiveness of distance learning. This study is unique in that two cohorts, distance learners and campus learners, were taught synchronously by the same faculty member. Quantitative measures of student learning outcomes were compared using SPSS. There were no significant differences in learning outcomes between distance learners and campus learners. This study provides empiric support for distance education as a means to address the nursing shortage.

Fostering Competencies in Future Teachers: A Competency-Based Approach to Teacher Education  [PDF]
Susan Cydis
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.513130
Abstract:

The study investigated the characteristics of instruction and assessment used by instructors in teacher education courses that foster student competencies as perceived by students. The sampling method used to collect the sample of instructors and their courses was purposive, non-probability sampling. Student participants included those that were currently registered in classes of the respective instructors. A qualitative analysis of the data collected revealed that instructors used a variety of competency-based educational practices in their instructional and assessment tasks and that students perceived themselves as competent in the areas identified by the Teacher Education Accreditation Council (2009) as standards for student competencies in teacher education courses.

Plagiarism: Whose Responsibility Is It Anyway? An Administrator’s Choice to Teach Not Punish  [PDF]
Susan Polirstok
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.58066
Abstract:


This paper examines how plagiarism is viewed on college campuses and the resultant punitive consequences that follow. In this case, a college administrator must determine whether two graduate education students should be expelled as a consequence of having certain passages appearing from websites and journal articles without attribution in first two theses drafts. In assessing what contributed to this infraction, the college administrator determined that the students had never received direct instruction in plagiarism and how to avoid it. Working collaboratively with the referring faculty member, a 3-session instructional program was designed to teach how to paraphrase and use citations in tandem with an overcorrection procedure of positive practice coupled with restitution. The culminating session required each student to design a 5-lesson module on plagiarism and how to avoid it for their program peers. They also met with their faculty instructor to review the changes they had made in their drafts resulting in reinstatement in their research course. The entire process helped the academic program faculty recognize that the topic of plagiarism and skills necessary to avoid plagiarism required direct instruction at various points throughout the overall program to prevent students from encountering severe penalties.


Suggested Strategies in Water Treatment by Using Situ Pressure in Reverse Osmosis  [PDF]
Susan Norouzi
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.55033
Abstract: Nowadays desalination is one of the main resources to obtain water in many areas. The most advanced method for water filtration is reverse osmosis. In this system, water is injected into semi-membranes by using power pumping, and its salt water is taken away from the solution. This paper has tried to offer guidelines to use the pressure createdin situof harvesting water, instead of utilizing power pump, which produces the necessary pressure for the reverse osmosis. These guidelines have been divided into 2 main groups: Using the created natural pressure, and the other way is using the pressures that are caused by the constructions built for harvesting water.
Classroom Management Strategies for Inclusive Classrooms  [PDF]
Susan Polirstok
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.610094
Abstract: Classrooms in the 21st century have by law become inclusive, typically comprised of general education and special needs students. Included students are those who present with mild to moderate learning and behavioral challenges. They add another layer of complexity to classroom management, requiring teachers to be highly structured, consistent and reinforcing. Teacher fidelity to behavioral expectations that have been established for the classroom is essential. Classroom management strategies discussed include changing the teacher approval to disapproval ratio, using selective ignoring, focusing on structure and routine, increasing student locus of control, de-escalating student aggression and hostility, and limiting the use of punishment. Hands-on strategies are highlighted.
Aircraft Clean Air Requirements Using Bleed Air Systems  [PDF]
Susan Michaelis
Engineering (ENG) , 2018, DOI: 10.4236/eng.2018.104011
Abstract: There are certification and airworthiness requirements relevant to the provision of clean breathing air in the crew and passenger compartments. There have been continuing reports and studies over the years regarding oil fumes in aircraft, including impaired crew performance. Oil fumes are viewed in varying ways ranging from rare seal bearing failures, to low level leakage in normal flight. A Masters of Science (MSc) research degree was undertaken to assess whether there is any gap between the certification requirements for the provision of clean air in crew and passenger compartments, and the theoretical and practical implementation of the requirements using the bleed air system. A comprehensive literature search reviewed applicable certification standards, documented and theoretical understanding of oil leakage. Two types of interviews were conducted to address the research questions. Key aviation regulators were questioned about the process by which they certify and ensure compliance with the clean air requirements. Aerospace engineers and sealing professionals were interviewed about their understanding of how oil may leak past compressor oil bearing seals, and into the air supply under various flight conditions. The outcome of the research showed that there is a gap between the clean air certification requirements, and the theoretical and practical implementation of the requirements using the bleed air system. Low level oil leakage into the aircraft cabin in normal flight operations is a function of the design of the engine lubricating system and bleed air systems, both utilising pressurised air. The use of the bleed air system to supply the regulatory required air quality standards is not being met or being enforced as required.
Faraday Filtering on the Cs-D$_1$-Line for Quantum Hybrid Systems
Matthias Widmann,Simone Portalupi,Sang-Yun Lee,Peter Michler,J?rg Wrachtrup,Ilja Gerhardt
Physics , 2015,
Abstract: Narrow-band filtering of light is widely used in optical spectroscopy. Atomic filters, which rely on the Faraday effect, allow for GHz-wide transmission spectra, which are intrinsically matched to an atomic transition. We present an experimental realization and a theoretical study of a Faraday anomalous dispersion optical filter (FADOF) based on cesium and its D$_1$-line-transition ($6^2S_{1/2}\rightarrow6^2P_{1/2}$) around 894nm. We also present the prospects and visions for combining this filter with the single photon emission of a single quantum dot (QD), which matches with the atomic transition.
Exchange-induced frustration in Fe/NiO multilayers
N. Rougemaille,M. Portalupi,A. Brambilla,P. Biagioni,A. Lanzara,M. Finazzi,A. K. Schmid,L. Duò
Physics , 2007, DOI: 10.1103/PhysRevB.76.214425
Abstract: Using spin-polarized low-energy electron microscopy to study magnetization in epitaxial layered systems, we found that the area vs perimeter relationship of magnetic domains in the top Fe layers of Fe/NiO/Fe(100) structures follows a power-law distribution, with very small magnetic domain cutoff radius (about 40 nm) and domain wall thickness. This unusual magnetic microstructure can be understood as resulting from the competition between antiferromagnetic and ferromagnetic exchange interactions at the Fe/NiO interfaces, rather than from mechanisms involving the anisotropy and dipolar forces that govern length scales in conventional magnetic domain structures. Statistical analysis of our measurements validates a micromagnetic model that accounts for this interfacial exchange coupling.
