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 ...

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. Głównym celem referatu jest zaprezentowanie próby pomiaru dobrobytu społeczno-ekonomicznego z wykorzystaniem modelowania miękkiego.

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 ...

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 ...

The RCT is the most rigorous design to determine whether some factor (exposure) causes an outcome. Using this design, participants are randomly allocated to be or not be exposed to a potential causative agent and then followed up to compare the number in each group who experience the outcome. In questions of causation, however, it may not be ethical or feasible to randomly allocate people to exposure to the causative agent. The next best evidence comes from cohort analytic studies. In this design, the investigator follows up people who are exposed to and not exposed to a causative agent. The major strength of RCTs and cohort analytic studies is that those entering the study have not yet experienced the outcome. The investigator is certain therefore that exposure to the causative agent (smoking) precedes the development of the outcome (lung cancer). This issue of temporality-that is, that the causative agent precedes the development of the outcome, is crucial for establishing a causal ...

The main aim of CesrIKi from the onset was to bring researchers from various disciplines to carry out research on Indigineous Knowledge (IK). Our approach has always been multidisciplinary. It was realised that various discplines were operating on their own to understand various research questions and this defeated the idea of understanding issues from different angles (discplines). The university is organised into Departments and we hardly know what other researchers do and the idea of bringing researchers from various disciplines was regarded as a noble idea to break academic boundaries (silos).. ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): No mixed methods research design blends typological and systemic approaches into a cohe-sive, multifaceted whole. A synergistic approach to mixed methods research uses the inher-ent strengths of both types of approaches, providing researchers with a comprehensive framework for making pivotal research design decisions. Grounded in both philosophy and practice, this approach enables researchers to identify what will be researched, how it will be researched, and why the research will be undertaken in their chosen way. Presented as a set of core principles and a conceptual framework, its practical application is illustrated through the authors experience of mixing methods in a randomized controlled trial (RCT). The synergistic approach discussed in this article offers researchers an alternative mixed methods research approach.

Selection of target sample size is a critical factor in the design of any randomized trial. Although calculations are straightforward, the underlying assumptions are frequently based on incomplete data. Relatively small errors in the assumptions can design a trial that is either substantially under- or overpowered.. One of the more rapidly evolving clinical trial methodological areas is that of adaptive clinical trials, where the study design is adjusted based on data collected as part of the initial conduct of the trial. Methods for adaptive trials are sometimes confused with the much more mature methodological area of group sequential trials.7-9 Shih eloquently relates that group sequential trial methodology has the goal of "saving lives or saving resources" whereas the adaptive clinical trial approach has the goal of "saving the study."10. There are 2 approaches of adaptive trial methodology. The first examines estimates of parameters that were assumed during the design phase of the project ...
We identified a high frequency of unacknowledged discrepancies and poor reporting of sample size calculations and data analysis methods in an unselected cohort of randomised trials. To our knowledge, this is the largest review of sample size calculations and statistical methods described in trial publications compared with protocols. We reviewed key methodological information that can introduce bias if misrepresented or altered retrospectively. Our broad sample of protocols is a key strength, as unrestricted access to such documents is often very difficult to obtain.11 Previous comparisons have been limited to case reports,6 small samples,12 13 specific specialty fields,14 and specific journals.15 Other reviews of reports submitted to drug licensing agencies did not have access to protocols.4 16 17. One limitation is that our cohort may not reflect recent protocols and publications, as this type of review can be done only several years after protocol submission to allow time for publication. ...

In this paper some methodological problems particularly relevant to case-control studies of injury are illustrated by reference to previous childhood injury case-control studies. In contrast to studies of disease, where person time constitutes the observational experience of interest, in injury studies person time engaged in a particular activity to often more appropriate. The implications for the definition of the study base are discussed. The potential for hospital admission bias in injury case-control studies is considered along with potential strategies for avoiding it. The importance of errors in exposure measurement, including those arising from inappropriate induction time assumptions, are illustrated. Finally, the potential for bias resulting from the combination of etiologically unrelated injury outcomes into a single outcome measure is illustrated and discussed. ...
If you have a question about this talk, please contact Professor John Rust.. Optimal design allows for estimating parameters of statistical models according to important optimality criteria, e. g., minimizing standard errors of estimators. Thus, optimal designs may considerably reduce the number of experimental units, such as respondents or items in empirical studies. For a long time, optimal design has not received much attention within psychology, but meanwhile interest for this subject is rapidly increasing as such designs are needed, e. g., in large scale assessment, adaptive testing or automatic item generation. In this presentation, first, fundamental principles of optimal design are introduced using well-known linear models, e. g. analysis of variance or simple regression. The rationale of adaptive, Bayesian, and minimax designs needed for nonlinear models will then be outlined. Such designs are presented for Item Response Theory (IRT) models, e.g., 1Pl and 2PL model or linear logistic ...

This paper concerns design considerations (kinetics and hydraulic criteria) for a biological nitrification-denitrification attached culture process for sewage treatment.. The treatment system is composed of two submerged filters. The first one, an anoxic reactor, denitrifies and retains wastewater suspended solids. The second one oxidizes organic carbon and ammonia nitrogen.. It was found that the main parameter for the system is the recycle ratio since it sets the real hydraulic detention time in reactors and determines the quantity of nitrogen available to the denitrification process. ...

In the common linear regression model the problem of determining optimal designs for least squares estimation is considered in the case where the observations are correlated. A necessary condition for the optimality of a given design is provided, which extends the classical equivalence theory for optimal designs in models with uncorrelated errors to the case of dependent data. If the regression functions are eigenfunctions of an integral operator defined by the covariance kernel, it is shown that the corresponding measure defines a universally optimal design. For several models universally optimal designs can be identified explicitly. In particular, it is proved that the uniform distribution is universally optimal for a class of trigonometric regression models with a broad class of covariance kernels and that the arcsine distribution is universally optimal for the polynomial regression model with correlation structure defined by the logarithmic potential. To the best knowledge of the authors ...

Optimal design is useful in improving the efficiencies of experiments with respect to a specified optimality criterion, which is often related to one or more statistical models assumed. In particular, sometimes chemical and biological studies could involve multiple experimental factors. Often, it is convenient to fit a nonlinear model in these factors. This nonlinear model can be either mechanistic or empirical, as long as it describes the unknown mechanism behind the response surface. In this thesis, our main interest is in exact optimal design of experiments for nonlinear multifactor models. In order to search for optimal designs, we can use the conventional point or coordinate exchange approach, which however can incorporate a new continuous optimisation method. On the basis of this idea, we further develop and implement a multistage hybrid method to construct local and (pseudo-)Bayesian optimal designs. The recommended hybrid exchange algorithm overcomes the shortcomings of the modified ...

TY - JOUR. T1 - Optimal designs for asymmetric sigmoidal response curves in bioassays and immunoassays. AU - Hyun, Seung Won. AU - Wong, Weng Kee. AU - Yang, Yarong. PY - 2020/2/1. Y1 - 2020/2/1. N2 - The 5-parameter logistic (5PL) model is frequently used to model and analyze responses from bioassays and immunoassays which can be skewed. Various types of optimal experimental designs for 2, 3 and 4-parameter logistic models have been reported but not for the more complicated 5PL model. We construct different types of optimal designs for studying various features of the 5PL model and show that commonly used designs in bioassays and immunoassays are generally inefficient for statistical inference. To facilitate use of such designs in practice, we create a user-friendly software package to generate various tailor-made optimal designs for the 5PL model and evaluate robustness properties of a design under a variation of criteria, model forms and misspecification in the nominal values of the model ...
The most difficult and most important considerations in planning the protocol of a case-control study are ascertainment of cases, selection of controls and the quality of the exposure measurement. Plans to ensure careful field work are equally important; without attention to data collection, the protocol will be meaningless. In most case-control studies, the measurement problem is magnified because one cannot implement the collection of exposure information at the beginning of follow-up, and instead must rely on interviews, existing records or extrapolation into the past. Consideration of a case-control study as an efficient way to study a cohort helps to resolve some design issues.
In recent years, the use of adaptive design methods in clinical research and development based on accrued data has become very popular due to its flexibility and efficiency. Based on adaptations applied, adaptive designs can be classified into three categories: prospective, concurrent (ad hoc), and …
By using an imaging device (30), it is possible to determine the concentration of flourescent pigments contained in a target sample (1). The imaging device has a plurality of detection wavelength bands. There are prepared a plurality of reference samples, each containing each of the flourescent pigments in a predetermined unit concentration, so as to obtain measurement intensity of flourescent light emitted from each reference sample at each detection wavelength band. The flourescent image of the target sample is imaged at each detection wavelength band by using the imaging device. By using the flourescent intensities obtained from the reference sample and the target sample, calculation is executed so as to obtain the concentration of each of the flourescent pigments in the target sample.

This paper presents a pilot study rationale and research methodology using a mixed media visualisation (3D printing and Augmented Reality simulation) learning intervention to help students in an ICT degree represent theoretical complex multi-step problems without a corresponding real world physical analog model. This is important because these concepts are difficult to visualise without a corresponding mental model. The proposed intervention uses an augmented reality application programmed with free commercially available tools, tested through an action research methodology, to evaluate the effectiveness of the mixed media visualisation techniques to teach ICT students networking. Specifically, 3D models of network equipment will be placed in a field and then the augmented reality app can be used to observe packet traversal and routing between the different devices as data travels from the source to the destination. Outcomes are expected to be an overall improvement in final skill level for all students
