Biomarker discovery studies have generated an array of omic data, however few novel biomarkers have reached clinical use. Guidelines for rigorous study designs are needed.. Biases frequently occur in sample selection, outcome ascertainment, or unblinded sample handling and assaying process. The principles of a prospective-specimen collection and retrospective-blinded-evaluation (PRoBE) design can be adapted to mitigate various sources of biases in discovery. We recommend establishing quality biospecimen repositories using matched two-phase designs to minimize biases and maximize efficiency. We also highlight the importance of taking the clinical context into consideration in both sample selection and power calculation for discovery studies.. Biomarker discovery research should follow rigorous design principles in sample se- lection to avoid biases. Consideration of clinical application and the corresponding biomarker performance characteristics in study designs will lead to a more fruitful ...

The first step when planning a RCR is to formulate a series of research questions that are to be answered based on results of the study. Research questions should be logical, flowing from that which is known or believed to be true to that which is unknown and requires validation [5]. Research questions form the initial structure of the RCR and guide the study design and data analysis. It is important to spend adequate time carefully scripting and revising the research questions for the study.. There is no shortage of published advice on developing and refining research questions . We have selected one framework for the design and articulation of research questions to present here which we have found to be particularly useful. Though not mentioned elsewhere in this manuscript, we recommend Morgan and Harmon [6] to the reader as an additional reference in properly framing research questions. The framework presented here is a typology of research questions. Such questions generally fall into one of ...
The main trial will need to address the issues normally posed by randomised controlled trials, such as sample size, inclusion and exclusion criteria, and methods of randomisation, as well as the challenges of complex interventions. Individual randomisation may not always be feasible or appropriate. For example, cluster randomisation is often used for trials of interventions directed at a practice or hospital team. 10 11 Randomised incomplete block designs have also been used to evaluate different approaches to promoting change in professional behaviour.12. It is often not possible to conceal allocation of treatment from the patient, practitioner, and researcher in complex intervention trials. The potential biases of unblinded trials therefore have to be taken into account. Dissimilar levels of patient commitment between intervention and control groups may cause differential dropout, making interpretation of results difficult. When patients have strong preferences, a preference trial design may ...

Randomisation, however, does not itself promote the applicability of the results to situations other than the one in which the trial was done. A tool published in 2009, PRECIS (PRagmatic Explanatory Continuum Indicator Summaries) aimed to help trialists design trials that produced results matched to the aim of the trial, be that supporting clinical ...

We see four potential barriers to adoption of clinically-integrated randomized trials: methodologic, technical, practical and regulatory. The methodologic issue is that. clinically-integrated randomized trials ask about the effectiveness of treatments in routine clinical practice. This is generally the domain of what are known as pragmatic trials, which cannot have the sort of rigorous controls associated with explanatory trials[23], such as blinding or careful outcome assessment (for example, in a diet trial, patients would weigh themselves). Instead, one would need to trust that there would not be important preferences - leading to bias - between different similar alternatives, and that the sort of large sample sizes possible with clinically-integrated trials - 10, 20 or 50 fold greater than with traditional trials - would offset any increase in variance associated with sub-optimal outcome assessment, or the possibility of cheating by a minority of participants with a vested interest in ...
We acknowledge that this is a single-case report reflecting one couples views on GA therapy and that these may not be shared by other parents in similar circumstances. Providing such a nuanced and detailed account of these parents reasoning precludes exhaustive review of ethical arguments surrounding GA, but these are well documented elsewhere.1 There is a clear need for further work to see whether our findings are replicated, and to consider the views of parents who choose not to access this treatment or who access it for different reasons. However, while the ethical considerations these parents thought important might not be ones other parents think matter, they are viewpoints that can be weighed in the balance and contribute to the quality of ethical argument. In this regard, we believe there are important insights to be gained from this report regarding how these parents characterise benefits and harms and their responsibilities as surrogate decision-makers.. One of these insights relates ...

This thesis studies the presence of different nationalist themes in the rhetoric of The United Kingdom Independence Partys (UKIP) manifestos for general elections between 1997 and 2018 exploring how the rhetoric of UKIPs manifestos use various nationalist themes and the continuity and change in the presence of these themes over time. The theoretical approach for this thesis consists of a set of modernist and contemporary nationalist theories utilising primarily the works of John Breuilly, Benedict Andersson and Michael Billig. Drawing from these theoretical concepts, three main categories were created for the nationalist themes: Distinct people, distinct history and distinct interests. This thesis conducts a longitudinal, single-case content analysis, that employs mixed methods by qualitatively coding the manifestos using a deductive coding frame, and by counting the assigned codes and providing a quantitative analysis on the presence of nationalist themes in the manifestos. The main ...

Dobrobyt społeczno-ekonomiczny to pojęcie złożone, które nie ma w literaturze precyzyjnego i jednoznacznego określenia, stąd trudności jego pomiaru. Wielu polityków, ekonomistów, międzynarodowe instytucje i media próbują wykorzystywać produkt krajowy brutto, czy też dochód narodowy, jako miernik dobrobytu. Jest to podejście niewłaściwe, gdyż jeden i ten sam miernik nie może poprawnie charakteryzować dwóch różnych merytorycznie agregatów - produkcji i dobrobytu. W badaniach społeczno-ekonomicznych podejmowane są próby wprowadzenia alternatywnych, czy też komplementarnych w stosunku do PKB mierników dobrobytu. Trwają poszukiwania formuły, stąd pomiar dobrobytu społeczno-ekonomicznego jest otwartym problemem badawczym.

What if policymakers, science reporters and even scientists cant distinguish between weak and trustworthy research studies that underlie our health care decisions?. Many studies of healthcare treatments and policies do not prove cause-and-effect relationships because they suffer from faulty research designs. The result is a pattern of mistakes and corrections: early studies of new treatments tend to show dramatic positive health effects, which diminish or disappear as more rigorous studies are conducted.. Indeed, when experts on research evidence do systematic reviews of research studies they commonly exclude 50%-75% because they do not meet basic research design standards required to yield trustworthy conclusions.. In many such studies researchers try to statistically manipulate data to adjust for irreconcilable differences between intervention and control groups. Yet it is these very differences that often create the reported, but invalid, effects of the treatments or policies that were ...
El presente documento expone algunas consideraciones teóricas y metodológicas para el desarrollo de un modelo de competencias críticas (MCC). Este se define como un conjunto de habilidades y conocimientos funcionalmente organizados que permiten alcanzar resultados medibles con consecuencias positivas para los objetivos estratégicos del negocio. Para el desarrollo de la propuesta, se abordaron planteamientos teóricos sobre el modelo clásico de competencias laborales, el modelo contemporáneo de competencias laborales y el modelo de competencia humana. la implementación del modelo contempla cinco pasos: 1) realizar un análisis del puesto considerando cuáles son las dimensiones o facetas que serán susceptibles de revisión; 2) identificar a las personas con los desempeños opuestos (los de desempeño superior y los de desempeño inferior); 3) identificar los incidentes críticos más relevantes al puesto; 4) desarrollar escalas de valoración de anclajes (eVA) y 5) validar las eVA ...

Not all research designs are concerned with generalising from a sample to a population of people. Qualitative studies use rich and deep description to inform our understanding of concepts and contribute to broader theoretical understanding. For example, Wilsons study of the experiences of older adults making the transition to life in a nursing home says nothing about the amount of experience or the probability of adjustment to a nursing home; instead, the author simply describes what that experience might be like.9 (See Evidence-Based Nursing 1998 Jul, p96.) On the basis of this description, the author proposes a 3 stage theory about the process of adjustment to a nursing home placement. What this means is that nurses should consider the possibility that these stages might need to be addressed with patients undergoing this transition. Good qualitative enquiry leads to theoretical generalisability rather than statistical inference.. Because we want to generalise about the shape or content of a ...
TY - GEN. T1 - Computer Analysis and Optimal Design of Mechine Elemennts. AU - Pedersen, Niels Leergaard. PY - 2015. Y1 - 2015. N2 - The subject machine elements is traditional a research field where standards have a significant influence on the design, i.e. the keyway in a shaft has a given shape and size dictated by a standard. This is important for the interaction between different elements produced at different locations, other examples of standardized components are bolts and gears. The standard designs are typically very good, many years of experience have gone into the design process. The design consists in most cases of straight lines and circular arches, not including e.g. the involute shape of gears. The standard cutting rack for the involute gear is however made from straight lines and circular arches. The optimization objective is strength and the focus is on fatigue. The designs are improved by lowering the stress concentrations that controls the strength. In the lecture the ...

Much biomedical research is observational. The reporting of such research is often inadequate, which hampers the assessment of its strengths and weaknesses and of a studys generalisability. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) initiative developed recommendations on what should be included in an accurate and complete report of an observational study. We defined the scope of the recommendations to cover three main study designs: cohort, case-control, and cross-sectional studies. We convened a 2-day workshop in September, 2004, with methodologists, researchers, and journal editors to draft a checklist of items. This list was subsequently revised during several meetings of the coordinating group and in e-mail discussions with the larger group of STROBE contributors, taking into account empirical evidence and methodological considerations.

Experimental Mechanics in Nano and Biotechnology: Experimental Research on Failure Mechanism of a CVI-Fabricated Ceramic Matrix Composite under Compression
The scientists singled out a messenger RNA (mRNA) in their research because it allows the production of two proteins needed for viral propagation. Production of the second protein requires the mRNA to undergo the process of splicing, in which two remote sites of the long molecule join together, while the intervening segment is discarded. We look at one of the splicing sites as a potential switch, said Turner. If we can inactivate the switch to prevent the two sites from coming together, we can stop the virus from spreading.. The scientists analyzed data from the sequencing of the influenza genome, which is available on a government database, in order to construct a 2-D rendering of the RNA molecule. By using a combination of computational and biochemical tools, they found that one of the splicing sites-referred to as 3-exists in either an exposed hairpin loop or a difficult-to-access pseudoknot. The scientists concluded that there are two ways to prevent splicing of the RNA strands. One ...

Many researchers favor repeated measures designs because they allow the detection of within-person change over time and typically have higher statistical power than cross-sectional designs. However, the plethora of inputs needed for repeated measures designs can make sample size selection, a critical step in designing a successful study, difficult. Using a dental pain study as a driving example, we provide guidance for selecting an appropriate sample size for testing a time by treatment interaction for studies with repeated measures. We describe how to (1) gather the required inputs for the sample size calculation, (2) choose appropriate software to perform the calculation, and (3) address practical considerations such as missing data, multiple aims, and continuous covariates.

I agree to the potential problems you mentioned about experimental design. But I can assure you all those problems (known as confounding(s)) are well known to researchers. But sometimes corners are cut because of convenience or sloppiness. One major criterion of scientific data is reliability, which in laymans term means the data must be replicable by other researchers. Because it is rare that multiple groups of researchers commit the same set of confoundings/experimental errors, so if data of all researchers converge (i.e, produce a similar pattern of results), we can be assured potential confoundings either do not exist or are irrelevant. The father of cloning in Korea got caught of fabricating data because other researchers could not replicate his data. -TT ...
