The following study examines the construction of the national tests in history. The study has analyzed the work processes of the construction of the test at different moments, such as design, conduct and evaluation, from the perspective of the test designers and the test manager at the National Agency for Education. The purpose is to see how the test designers’ previous experiences are reflected in the work process with national test and what problems, challenges and limitations they have in their work. The study is based on qualitative interviews and has used the validity theory as an analytical framework. The results show, among other things, that the work process of the national tests begins with the group interpreting the curriculum for history. The interpretation is written down in the so-called construct which is sent to the National Agency for Education for further review. The test designers performed various evaluations of the tests throughout the whole work process. The National Agency for Education conducted a large survey after completing tests that the teachers answer. The results also show different limitations, problems, and challenges of the test design. The framework of the test limits for example the design; what the test should look like, pictures and question construction, it systematizes the test. The processes of the conduction of the test in schools is also completely controlled by the National Agency for Education and the test does not necessarily reflect the teaching that is conducted in the classroom. Another problem is that communication with the active teachers is rather one-sided. Challenges that the test designers face includes setting grade requirements and stable results.

Two-dimensional scan design is an effective BIST architecture that uses multiple scan chains in parallel to test the Circuit Under Test (CUT). Linear Finite State Machines (LFSMs) are often used as on-board Pseudo Random Pattern Generators (PRPGs) in two-dimensional scan designs. However, linear dependencies present in the LFSM generated test-bit sequences adversely affect the resultant fault coverage in two-dimensional scan designs. In this work, we present methods that improve the resultant fault coverage in two-dimensional scan designs through the minimization of linear dependencies. Currently, metric of channel separation and matrix-based metric are used in order to estimate linear dependencies in a CUT. When the underlying sub-circuit (cone) structure of a CUT is available, the matrix-based metric can be used more effectively. Fisrt, we present two methods that use matrix-based metric and minimize the overall linear dependencies in a CUT through explicitly minimizing linear dependencies in the highest number of underlying cones of the CUT. The first method minimizes linear dependencies in a CUT through the selection of an appropriate LFSM structure. On the other hand, the second method synthesizes a phase shifter for a specified LFSM structure such that the overall linear dependencies in a CUT are minimized. However, the underlying structure of a CUT is not always available and in such cases the metric of channel separation can be used more effectively. The metric of channel separation is an empirical measure of linear dependencies and an ad-hoc large channel separation is imposed between the successive scan chains of a two-dimensional scan design in order to minimize the linear dependencies. Present techniques use LFSMs with additional phase shifters (LFSM/PS) as PRPGs in order to obtain desired levels of channel separation. We demonstrate that Generalized LFSRs (GLFSRs) are a better choice as PRPGs compared to LFSM/PS and obtain desired levels of channel separations at a lower hardware cost than the LFSM/PS. Experimental results corroborate the effectiveness of the proposed methods through increased levels of the resultant fault coverage in two-dimensional scan designs.

Traditional methods to test integrated circuits (ICs) require enormous amount of memory, which make them increasingly expensive and unattractive. This thesis addresses this issue for scan-based designs by proposing a method to compress and decompress input test patterns. By storing the test patterns in a compressed format, the amount of memory required to test ICs can be reduced to manageable levels. The thesis describes the compression and decompression scheme in details. The proposed method relies on the insertion of a decompression unit on the chip. During test application, the patterns are decompressed by the decompression unit as they are applied. Hence, decompression is done on-the-fly in hardware and does not slow down test application.
The design of the decompression unit is treated in depth and a design is proposed that minimizes the amount of extra hardware required. In fact, the design of the decompression unit uses flip-flops already on the chip: it is implemented without inserting any additional flip-flops.
The proposed scheme is applied in two different contexts: (1) in (external) deterministic-stored testing, to reduce the memory requirements imposed on the test equipment; and (2) in built-in self test, to design a test pattern generator capable of generating deterministic patterns with modest area and memory requirements.
Experimental results are provided for the largest ISCAS'89 benchmarks. All of these results point to show that the proposed technique greatly reduces the amount of test data while requiring little area overhead. Compression factors of more than 20 are reported for some circuits.

A key design constraint of circuits used in hand-held devices is the power consumption, mainly due to battery life limitations. Adaptive power management (APM) techniques aim to increase the battery life by adjusting the supply voltage (Vdd) and operating frequency, according to the workload. APM-enabled devices raise a number of challenges for existing manufacturing test and diagnosis techniques, as certain defects exhibit Vdd dependent detectability. This means that to achieve 100% fault coverage, APM-enabled devices should be tested at all operating voltages using repetitive tests. Repetitive tests at several Vdd settings are undesirable as it increases the cost of manufacturing test. This thesis provides two new and cost-effective Design for Test (DFT) techniques to avoid repetitive tests thereby reducing test cost. The first technique uses test point insertion (TPI) to reduce the number of test Vdd settings. TPI capitalizes on the observation that each resistive bridge defect consists of a large number of logic faults, including detectable and non-detectable logic faults. It targets resistive bridges requiring test at higher Vdd settings, and converts un-detectable logic faults at the lowest Vdd setting, into detectable logic faults by using test points. Test points provide additional controllability and observability at the fault site. TPI has shown encouraging results in terms of reducing the number of test Vdd settings, however it does not achieve single Vdd test for all designs. Taking this issue into account, another gate sizing (GS) based DFT technique is proposed. It targets bridges that require multi-Vdd test and increases the drive strength of gates driving such bridges. The number of test Vdd settings are reduced minimizing test cost. Experimental results show that for all designs, the proposed GS technique achieves 100% fault coverage at a single Vdd setting; in addition it has a lower overhead than the TPI in terms of timing, area and power. The Vdd dependent detectability of resistive bridges demands re-evaluation of existing diagnosis techniques, as all existing techniques use a single voltage setting for fault diagnosis, which may have a negative impact on diagnosis accuracy, affecting subsequent design cycle and yield. This thesis proposes a novel and cost-effective technique to improve diagnosis accuracy of resistive bridges in APM-enabled designs. It evaluates the impact of varying supply voltage on the accuracy of diagnosis and demonstrates how additional voltage settings can be leveraged to improve the diagnosis accuracy through a novel multi-voltage diagnosis algorithm. The diagnosis cost is reduced by identifying the most useful voltage settings and by eliminating tests at other voltages thereby achieving high diagnosis accuracy at reduced cost. All developed test and diagnosis techniques have been validated using simulations with ISCAS and ITC benchmarks, realistic fault models and actual bridges extracted from physical layouts.

The dialysis membrane is a key component of the haemodialyser. Determination of the membrane solute permeation and ultrafiltration characteristics is important in predicting haemodialyser performance. In some membrane permeation test cells, there are additional mass transfer resistances present due to fluid films adjacent to the membrane surface. This can mask the true permeability of the membrane. Test cell designs should therefore seek to minimise or eliminate any fluid film resistances In this project, solute permeability results were compared using two types of permeation test cells, namely a radial flow cell and a dynamic test cell. In the radial flow cell, fluid streams are directed perpendicular to the membrane surfaces in an attempt to reduce the fluid film thickness. In the dynamic test cell, the fluid streams are passed at high velocity through an open-pore rigid metal support structure that generates localised mixing at the membrane surfaces. Fluid film resistances are proportionately greater for the transfer of low molecular weight solutes and for high flux membranes. Therefore, the transfer of urea (60 mol wt) was studied in a polyacrylonitrile-based membrane AN69ST. Permeability of a higher molecular weight solute, caffeine, (194.2 mol wt) was also determined.

Throughout Central Florida surface water and ground water are decreasing in quantity and quality in part because of excess Nitrate and Phosphorus nutrients. Stormwater runoff serves as a medium for transport of Nitrate and Phosphorus to surface water and ground water. The goal of this experiment is assess the Nitrate and Phosphorus removal in stormwater using select media. The results of a literature search, batch test experimentation and column test experimentation are used to determine an optimal media blend that may be implemented in detention ponds to reduce Nitrate and Phosphorus. The extensive literature search revealed 32 different media that may be used to remove Nitrate and Phosphorus. Each potential media was qualitatively and quantitatively evaluated based on 5 criteria: 1) relevance, 2) permeability, 3) cost, 4) availability in Florida, and 5) additional environmental benefit. The top 7 performing media: Florida peat, sandy loam, woodchips, crushed oyster shell; crushed limestone, tire crumb and sawdust were selected for batch test experimentation. The aerobic conditions in batch test experimentation prohibited the growth of denitrifying bacteria, therefore media mixes were selected for column test experimentation based on Ammonia and Orthophosphate concentrations. Batch test experimentation showed the most effective media to be 50% sand, 30% tire crumb, 20% sawdust by weight (media mix 1) and 50% sand, 25% sawdust, 15% tire crumb, 10% limestone by weight (media mix 2). Media mix 1, media mix 2 and a control are tested in column test experimentation, where the control is site soil from Hunters Trace development in Ocala, Florida. Column test experimentation models a dry detention pond where water passes through a 48 inch unsaturated zone then a 48 inch saturated zone. To test Nitrate and Orthophosphate removal potential, pond water augmented with Nitrate (0.38, 1.26, 2.5 mg/L NO3-N) and Orthophosphate (0.125, 0.361, 0.785 mg/L PO4-P) was pumped into the columns. Media mix 1 and media mix 2 outperformed the control in both Nitrate and Orthophosphate removal. Media mix 1 and media mix 2 had Nitrate removal efficiencies ranging from 60% to 99% and the control had Nitrate removal efficiencies ranging from 38%-80%. Media mix 1 and media mix 2 averaged Orthophosphate removal efficiencies ranging from approximately 42% to 67%. For every run in every influent Orthophosphate concentration the saturated control added Orthophosphate to the water. The Nitrate and Orthophosphate removal performances for media mix 1 and media mix 2 could not be directly compared because of different influent saturated nutrient concentrations.

A number of representative seed lots of both upland and Pima cotton cultivars and experimental strains have been evaluated utilizing two instruments which measure relative seed coat strength. Seed coat strength was found to have a strong genetic component of determination, with relatively minor influence of environment and year of production being observed Greater seed coat strengths should contribute to the relative resistance to seed damage and cracking during picking ginning and conditioning operations. It may be possible to incorporate this trait into cotton cultivars by mass selection techniques.

The multiple-choice test question is a popular item format used for tests ranging from classroom assessments to professional licensure exams. The popularity of this format stems from its administration and scoring efficiencies. The most common multiple-choice format consists of a stem that presents a problem to be solved accompanied by a single correct answer and two, three, or four incorrect answers. A well-constructed item using this format can result in a high quality assessment of an examinee's knowledge, skills and abilities. However, for some complex, higher-order knowledge, skills and abilities, a single correct answer is often insufficient. Test developers tend to avoid using multiple correct answers out of a concern about the increased difficulty and lower discrimination of such items. However, by avoiding the use of multiple correct answers, test constructors may inadvertently create validity concerns resulting from incomplete content coverage and construct irrelevant variance. This study explored an alternative way of implementing multiple-choice questions with two or more correct answers by specifying in each question the number of answers examinees should select instead of using the traditional guideline to select all that apply. This study investigated the performance of three operational exams that use a standard multiple-choice format where the examinees are told how many answers they are to select. The collective statistical performance of multiple-choice items that included more than one answer that is keyed as correct was compared with the performance of traditional single-answer, multiple-choice (SA) items within each exam. The results indicate that the multiple-answer, multiple-choice (MA) items evaluated from these three exams performed at least as well as to the single-answer questions within the same exams.

This study applied the latest developments in language testing validation theory to derive a core body of evidence that can contribute to the validation of a large-scale, high-stakes English as a Foreign Language (EFL) testing program in Japan. The testing program consists of a set of seven level-specific tests targeting different levels of proficiency. This core aspect of the program was selected as the main focus of this study. The socio-cognitive model of language test development and validation provided a coherent framework for the collection, analysis and interpretation of evidence. Three research questions targeted core elements of a validity argument identified in the literature on the socio-cognitive model. RQ 1 investigated the criterial contextual and cognitive features of tasks at different levels of proficiency, Expert judgment and automated analysis tools were used to analyze a large bank of items administered in operational tests across multiple years. RQ 2 addressed empirical item difficulty across the seven levels of proficiency. An innovative approach to vertical scaling was used to place previously administered items from all levels onto a single Rasch-based difficulty scale. RQ 3 used multiple standard-setting methods to investigate whether the seven levels could be meaningfully related to an external proficiency framework. In addition, the study identified three subsidiary goals: firstly, toevaluate the efficacy of applying international standards of best practice to a local context: secondly, to critically evaluate the model of validation; and thirdly, to generate insights directly applicable to operational quality assurance. The study provides evidence across all three research questions to support the claim that the seven levels in the program are distinct. At the same time, the results provide insights into how to strengthen explicit task specification to improve consistency across levels. This study is the largest application of the socio-cognitive model in terms of the amount of operational data analyzed, and thus makes a significant contribution to the ongoing study of validity theory in the context of language testing. While the study demonstrates the efficacy of the socio-cognitive model selected to drive the research design, it also provides recommendations for further refining the model, with implications for the theory and practice of language testing validation.

As a low fidelity work simulation, Situational Judgment Tests (SJTs) are an affordable and practical way of empirically linking training and on-the-job performance, thereby providing a viable means of evaluating training effectiveness. An issue, when utilizing SJTs, is deciding the appropriate manner in which the SJT should be scored. Traditional SJT scoring methodologies, while successfully utilized for selection and prediction, pose specific challenges when applied to a SJT designed to evaluate the effectiveness of a training program. This study discusses the shortcomings of traditional SJT scoring methodologies when used in the evaluation context. To overcome these challenges, an innovative scoring methodology, the Hybrid methodology, is presented. This study provides the detailed description of the Hybrid scoring key creation, and compares the Hybrid scoring key with two traditional scoring keys (Subject Matter Expert (SME) and Respondent-based scoring keys). Responses from a military training program are utilized to illustrate the distinctive effects of using the three different scoring approaches. The superiority of the hybrid scoring key, due to increased confidence in the keyâ s accuracy, and findings regarding training evaluation are discussed. Future research directions and practical applications of the research are also discussed.

The purpose of this paper is to present a new nonparametric test statistic for testing against ordered alternatives in a Balanced Incomplete Block Design (BIBD). This test will then be compared with the Durbin test which tests for differences between treatments in a BIBD but without regard to order. For the comparison, Monte Carlo simulations were used to generate the BIBD. Random samples were simulated from: Normal Distribution; Exponential Distribution; T distribution with three degrees of freedom. The number of treatments considered was three, four and five with all the possible combinations necessary for a BIBD. Small sample sizes were 20 or less and large sample sizes were 30 or more. The powers and alpha values were then estimated after 10,000 repetitions.The results of the study show that the new test proposed is more powerful than the Durbin test. Regardless of the distribution, sample size or number of treatments, the new test tended to have higher powers than the Durbin test.

The HIMS test, which consists of controlled exercise at increasing workloads, has been developed to monitor changes in training status and accumulative fatigue in athletes. As the workload can influence the day-to-day variation in heart rate, the exercise intensity which is associated with the highest sensitivity needs to be established with the goal of refining the interpretability of these heart rate measurements. The aim of the study was to determine the within subject day-to-day variation of submaximal and recovery heart rate in subjects who reached different exercise intensities.

This study explores and describes the processes of formative evaluation as carried out by content experts and instructional designers. It assumes that formative evaluation is an ill-defined, complex, problem solving task. Six experts (three Content Experts and three Instructional Designers), participated in this descriptive study. Subjects reviewed and revised a unit from a draft version of a self-instructional module on microbiology, while thinking aloud. Two coding schemes were developed and applied to the think-aloud protocols. Overall inter-coder reliability exceeded 89%. Qualitative data were used to describe the processes of formative evaluation, convergence patterns, and the degree of specificity of comments across subjects. Results suggest that there were between group differences in task representation, in the employed strategies, and in features of the text which were commented upon more frequently. Within group similarities in the outcome of formative evaluation were salient on a superficial level. Within group differences were more apparent when comments were compared qualitatively.

A number of randomization statistical procedures have been developed to analyze the results from single-case multiple-baseline intervention investigations. In a previous simulation study, comparisons of the various procedures revealed distinct differences among them in their ability to detect immediate abrupt intervention effects of moderate size, with some procedures (typically those with randomized intervention start points) exhibiting power that was both respectable and superior to other procedures (typically those with single fixed intervention start points). In Investigation 1 of the present follow-up simulation study, we found that when the same randomization-test procedures were applied to either delayed abrupt or immediate gradual intervention effects: (1) the powers of all of the procedures were severely diminished; and (2) in contrast to the previous study's results, the single fixed intervention start-point procedures generally outperformed those with randomized intervention start points. In Investigation 2 we additionally demonstrated that if researchers are able to successfully anticipate the specific alternative effect types, it is possible for them to formulate adjusted versions of the original randomization-test procedures that can recapture substantial proportions of the lost powers.

This paper describes a usability study of a responsive website prototype. A heuristic evaluation was conducted with three evaluators with a background in HCI, and user tests with four potential users were conducted as a control method to test the relevance of the heuristic evaluation result. The study showed that the website prototype failed the visibility of system status, user control and freedom and error prevention heuristics in the heuristic evaluation. However, the users responses contradict that result by showing that the users had no problems with those areas in the user tests. In fact, the users detected no usability problems at all. This could mean that those heuristics are not relevant for a responsive Web 2.0 site and needs to be removed when conducting a heuristic evaluation of a responsive website in the future, and that designing for responsiveness leads to higher usability. This study shows some indications but more testing needs to be done, preferably on several fully developed responsive websites, to be able to make any real conclusions about the usability of a responsive website and the relevance of the heuristics used in this study.

The Freight Warehouse Architecture Studio is adjacent to Virginia Commonwealth University in Richmond. Although designed as an adaptive reuse, it is a direct result of two things: a reading of Eisenman's Koizumi Project and working in the office for a few weeks immediately proceeding commencement on the studio. The reading was the onset of the theory necessary for the study, and the experience in the office offered the opportunity to establish the direction for the project. The question of culture, understanding, and reading yields the question of the reconciliation of personal history and community history, how an architect intervenes in a location fraught with tradition. As a result, there is "a condition of a space evolving from within, not an insertion, from without.... So what is interesting about this space is we set up the mechanism of interplay, but we did not know what was going to happen. In other words, I am not saying it is a beautiful design.... In a sense it is mediated because the hand of design is taken away..."

In this thesis, a test platform based on real-time facilities and embedded software is designed to verify the performance of a controller model in real time. By the help of this platform, design errors can be detected earlier and possible problems can be solved cost-effectively without interrupting the development process. An unmanned combat air vehicle (UCAV) model is taken as a plant model due to its importance in current and future military operations. Among several autopilot modes, the altitude hold mode is selected since it is an important pilot-relief mode and widely used in aviation. A discrete PID controller is designed in MATLAB/Simulink environment for using in verification studies. To control the dynamic system in wide range, a gain scheduling is employed where the altitude and velocity are taken as scheduling variables. Codes for plant and controller model are obtained by using real time workshop embedded coder (RTWEC) and downloaded to two separate computers, in which xPC kernel and VxWorks operating system are run, respectively. A set of flight test scenarios are generated in Simulink environment. They are analyzed, discussed, and then some of them are picked up to verify the platform. These test scenarios are run in the setup and their results are compared with the ones obtained in Simulink environment. The reusability of the platform is verified by using a commercial aircraft, Boeing 747, and its controller models. The test results obtained in the setup and in Simulink environment are presented and discussed.

Statistics
Ph.D.
Sigmoid curves have found broad applicability in biological sciences and biopharmaceutical research during the last decades. A well planned experiment design is essential to accurately estimate the parameters of the model. In contrast to a large literature and extensive results on optimal designs for linear models, research on the design for nonlinear, including sigmoid curve, models has not kept pace. Furthermore, most of the work in the optimal design literature for nonlinear models concerns the characterization of minimally supported designs. These minimal, optimal designs are frequently criticized for their inability to check goodness of fit, as there are no additional degrees of freedom for the testing. This design issue can be a serious problem, since checking the model adequacy is of particular importance when the model is selected without complete certainty. To assess for lack of fit, we must add at least one extra distinct design point to the experiment. The goal of this dissertation is to identify optimal or highly efficient designs capable of checking the fit for sigmoid curve models. In this dissertation, we consider some commonly used sigmoid curves, including logistic, probit and Gompertz models with two, three, or four parameters. We use D-optimality as our design criterion. We first consider adding one extra point to the design, and consider five alternative designs and discuss their suitability to test for lack of fit. Then we extend the results to include one more additional point to better understand the compromise among the need of detecting lack of fit, maintaining high efficiency and the practical convenience for the practitioners. We then focus on the two-parameter Gompertz model, which is widely used in fitting growth curves yet less studied in literature, and explore three-point designs for testing lack of fit under various error variance structures. One reason that nonlinear design problems are so challenging is that, with nonlinear models, information matrices and optimal designs depend on the unknown model parameters. We propose a strategy to bypass the obstacle of parameter dependence for the theoretical derivation. This dissertation also successfully characterizes many commonly studied sigmoid curves in a generalized way by imposing unified parameterization conditions, which can be generalized and applied in the studies of other sigmoid curves. We also discuss Gompertz model with different error structures in finding an extra point for testing lack of fit.

General attrition rates in drug development pipeline have been recognized as a necessity to shift gears towards new methodologies that allow earlier and correct decisions, and the optimal use of all information accrued throughout the process. The quantitative science of pharmacometrics using pharmacokinetic-pharmacodynamic models was identified as one of the strategies core to this renaissance. Coupled with Optimal Design (OD), they constitute together an attractive toolkit to usher more rapidly and successfully new agents to marketing approval. The general aim of this thesis was to investigate how the use of novel pharmacometric methodologies can improve the design and analysis of clinical trials within drug development. The implementation of a Monte-Carlo Mapped power method permitted to rapidly generate multiple hypotheses and to adequately compute the corresponding sample size within 1% of the time usually necessary in more traditional model-based power assessment. Allowing statistical inference across all data available and the integration of mechanistic interpretation of the models, the performance of this new methodology in proof-of-concept and dose-finding trials highlighted the possibility to reduce drastically the number of healthy volunteers and patients exposed to experimental drugs. This thesis furthermore addressed the benefits of OD in planning trials with bio analytical limits and toxicity constraints, through the development of novel optimality criteria that foremost pinpoint information and safety aspects. The use of these methodologies showed better estimation properties and robustness for the ensuing data analysis and reduced the number of patients exposed to severe toxicity by 7-fold. Finally, predictive tools for maximum tolerated dose selection in Phase I oncology trials were explored for a combination therapy characterized by main dose-limiting hematological toxicity. In this example, Bayesian and model-based approaches provided the incentive to a paradigm change away from the traditional rule-based “3+3” design algorithm. Throughout this thesis several examples have shown the possibility of streamlining clinical trials with more model-based design and analysis supports. Ultimately, efficient use of the data can elevate the probability of a successful trial and increase paramount ethical conduct.

In the course of revitalizing the Poseidon Building in Frankfurt, an energetically optimized façade, made of architectural concrete was developed. The development of a fiber-reinforced architectural concrete had to consider the necessary mechanical strength, design technology and surface quality. The fiber-reinforced architectural concrete has a compressive strength of 104.1 MPa and a 3-point bending tensile strength of 19.5 MPa. Beyond that, it was ensured that the fiber-reinforced high-performance concrete had a high durability, which has been shown by the capillary suction of de-icing solution and freeze thaw test with a weathering of abrasion of 113 g/m² after 28 freeze-thaw cycles and a mean water penetration depth of 11 mm.

A large scale automated test set was designed and built to address the varied accelerated life test requirements of the GaAs industry. GaAs low-noise/small-signal MESFETs with 1 x 300 micron gate peripheries and 3 different gate structures were subjected to a 1000 hour high temperature storage test: 1) to compare the reliability performance and manufacturability of a) recessed-gate MESFETs with TiPdAu gates b) realigned self-aligned gate (RSAG) MESFETs with TiWN_x Schottky and TiPdAu overlay c) planarized self-aligned gate (PSAG) MESFETs with TiWN_x Schottky and TiPdAu overlay. 2) to study the changes in I_dss, R_g, R_o, g_m, and V_p over time and their effects upon MAG (Maximum Available Gain). 3) to study failure criteria and their applicability toward accurate life predictions. The recessed-gate devices suffered from Au/GaAs channel interdiffusion resulting in substantial dc parameter degradation above 225°C with an activation energy of 1.7 eV. Although the most widely used device structure in the GaAs industry, its process is not conducive to parameter uniformity. The realigned self-aligned gate (RSAG) devices are an initial attempt at the fabrication of a self-aligned gate analog MESFET. They were found to exhibit excellent electrical characteristics, but their reliability performance was unpredictable due to the critical nature of the .5 micron TiPdAu gate overlay realignment to a 1 micron TiWN_x Schottky. Planarized self-aligned gate (PSAG) devices were found to be readily manufacturable and to exhibit excellent reliability. The use of a decrease in MAG was found to be a more meaningful failure criterion than a 20% change in I_dss, which is employed extensively in the literature.

Two modalities of research design's workshops -long and short- were developed to qualify 658 Hispanamerican research workers, whom were divided into 30 groups, and were applyied along ten years. The terminal efficiency of the workshops was measured with a pre-post-test design and the differences were assessed with a t-test -for dependent samples-. The results showed that the values of the post-test were higher -p ≤ 0.001- than the pretest averages. Contrasting the two workshop versions, the average of the long workshop was significantly higher -p ≤ 0.001- than the short one, by means of a multiple pre-post-test design and the t-test for independent samples. Using Solomon four-group design it was feasible to establish that the significant increase of knowledge about research designs was not influenced by the interaction of the pretest and treatment factors and there was not observed any significant difference between both versions.
Se aplicaron dos modalidades de talleres de investigación -corta y larga- para habilitar por espacio de diez años a 658 investigadores hispanoamericanos, divididos en 30 grupos. La eficiencia terminal de los talleres fue medida con un diseño de pre y post-test y las diferencias con una prueba t-Student -para muestras dependientes-. Los resultados mostraron que los valores del post-test eran más elevados -p ≤ 0.001- que los del pretest. Contrastando las dos versiones del taller, el promedio del largo fue significantemente mayor -p ≤ 0.001- que el del corto; esto, bajo la tutela de un diseño múltiple de pre y post-test y la prueba t-Student, pero para muestras independientes. Con el diseño de cuatro grupos de Solomon se estableció que el incremento significativo en el conocimiento sobre diseños de investigación no fue intervenido por los factores tratamiento y pretest -interacción- y no se observaron diferencias significativas entre ambas versiones.
