Abstract:
Negative testing deals with an important problem of assessing a system ability to handle unexpected situations. Such situations, if unhandled, may lead to system failures that in some cases can have catastrophic consequences. This paper presents a mutation testing-based approach for generation of test cases supporting negative testing. Application of this approach can provide, in a systematic and human-unbiased way, test cases effectively testing wide range of unexpected situations. Thus, it can contribute to improvement of a tested system. The paper formally defines mutation operators used to control the generation process, describes a generic framework for the generation and execution of the test cases, and explains how to interpret results.

Abstract:
Negative impacts of high-stakes testingHigh-stakes testing is not a new phenomenon in education. It has become part of the education system in many countries. These tests affect the school systems, teachers, students, politicians and parents, whether that is in a positive or negative sense. High-stakes testing is associated with concepts such as a school's accountability, funding and parental choice of school. The study aims to explain high-stakes testing, how it is created and developed in selected countries and look at the negative impacts of tests on various actors within this relationship.

Abstract:
A false negative can happen in many kinds of medical tests, regardless of whether they are screening or diagnostic in nature. However, it inevitably poses serious concerns especially in a prenatal setting because its sequelae can mark the birth of an affected child beyond expectation. False negatives are not a new thing because of emerging new tests in the field of reproductive, especially prenatal, genetics but has occurred throughout the evolution of prenatal screening and diagnosis programs. In this paper we aim to discuss the basic differences between screening and diagnosis, the trade-offs and the choices, and also shed light on the crucial points clinicians need to know and be aware of so that a quality service can be provided in a coherent and sensible way to patients so that vital issues related to a false negative result can be appropriately comprehended by all parties.

Abstract:
Abstract Background: Thrombotic thrombocytopenic purpura (TTP) presents with microangiopathic hemolytic anemia and thrombocytopenia and is caused by severe ADAMTS13 deficiency. TTP can be the result of autoantibodies to ADAMTS13 or genetic defect in the ADAMTS13 gene. ADAMTS-13 is an enzyme that specifically cleaves unusually large von Willebrand Factor (VWF) multimers which mediate platelet thrombus formation under high shear. When ADAMTS13 is deficient, unusually large VWF multimers accumulate causing excessive platelet aggregation and thrombosis in the microvasculature. Methods: St. Michael's Hospital, Toronto is home to a large reference laboratory for special coagulation. We use a commercial ELISA Technoclone Technozym ADAMTS-13 activity assay for the determination of ADAMTS-13 activity and Technoclone Technozym ADAMTS-13 inhibitor assay to identify anti-ADAMTS-13 antibodies. We send samples to another Canadian laboratory for validation of our results as they use an in-house ELISA assay for ADAMTS13 activity and anti-ADAMTS13 antibody. Results: We performed a retrospective review of all ADAMTS13 activity tests performed by our laboratory between January 1, 2013 and June 30, 2018. The total number of tests was 466 from 203 unique patients. 24% had an ADAMTS-13 activity under 10% (N = 144) which is consistent with the diagnosis of TTP. When specimens with severe ADAMTS-13 deficiency were tested for presence of anti-ADAMTS13 antibody, 46% were negative. Four of these specimens were sent to the other laboratory and all had detectable, albeit very low titre, inhibitors. Furthermore, on repeated testing over the study period, the vast majority of patients who presented with low ADAMTS13 activity and no detectable antibody subsequently became antibody positive. Fifty-two patients remained antibody negative by our internal and send-out testing. Five of them were known to have or were subsequently diagnosed with hereditary TTP (hTTP). Only one patient continues to have negative antibody but whose clinical course is not consistent with hTTP. Conclusions: We found that a commercial ADAMTS13 (Technoclone Technozym) antibody assay is falsely negative in a substantial proportion of patients with autoimmune TTP, the majority of which likely had a low titer inhibitor, below the threshold of test detection. More sensitive assays and/or repeated testing, presumably as inhibitor titre increases during the course of the disease, may detect antibody presence in the majority of samples of patients with autoimmune TTP. This is an important finding as this could impact the types of therapies offered to patients with negative antibody screens and may also avoid unnecessary, expensive genetic testing .

Full text
Abstract:
An automated system for quantitative respirator fit testing by negative pressure was evaluated by comparison testing with a computerized aerosol fit test system (Dynatech Frontier Model 260A). The new negative pressure system measures leakage flow while inspiratory pressures are sustained in a respirator facepiece rather than by pressure decay. Four phases of comparison testing were graduated by level of control, ranging from non-subject tests with hypodermic needle leakages to fit tests of 125 Air Force personnel. Throughout the series of tests, negative pressure fit factors were consistently more conservative than aerosol fit factors and showed less variability. Leakage flow rates measured by the negative pressure instrument were highly correlated with leak needle cross-sectional area as predicted by principles of air-flow physics. Comparison of subject and non-subject generated aerosol fit factors indicated significant aerosol losses, possibly due to streamlining and respiratory tract deposition. Negative pressure fit factors were not affected by these subject-related losses.

Full text
Abstract:
A number of clinicians have reported that narcissists show grandiosity in self-concept, and rage after receiving disconfirming feedback. This is the first empirical study to test these claims. Subjects with differing levels of narcissism and self-esteem were compared on distortion in self-perception and emotional reaction to negative feedback. Ninety-six college students predicted their levels of intelligence, attractiveness, and interpersonal understanding (empathy) as compared to their peers. Objective measures of these characteristics were obtained, and subjects' predictions, with their actual scores held constant, provided measures of reality distortion in selfperception. Subjects were given feedback comparing their predictions to objective measures at the end of the experiment, and reaction to feedback was assessed by comparing subjects' pre- and post-feedback scores on the Multiple Affect Adjective Checklist-Revised (Zuckerman & Lubin, 1985). Narcissists were expected to react to negative feedback with greater hostility than nonnarcissists. Narcissists evidenced significant distortion in perceptions of their own intelligence, attractiveness, and interpersonal understanding. This finding provided empirical evidence supporting the clinical phenomenon of grandiosity. Narcissists did not react with greater hostility after negative feedback, but as compared to nonnarcissists, they did react with less depression following negative feedback. This supported Kernberg's (1980) assertion that narcissists do not react to loss with depression. In contrast to the inflated self-image associated with narcissism, self-esteem was associated with a comparatively accurate view of self.

Abstract:
The goal of this project is to study novel nanoscale excitation volumes, sensitive enoughto study individual chromophores and go on to study new and exciting self assemblyapproaches to this problem. Small excitation volumes may be engineered using light con-finement inside apertures in metal films. These apertures enhance fluorescence emissionrates, quantum yields, decrease fluorescence quenching, enable higher signal-to-noiseratios and allow higher concentration single chromophore fluorescence, to be studied byrestricting this excitation volume. Excitation volumes are reported on using the chro-mophore's fluorescence by utilising fluorescence correlation spectroscopy, which monitorsfluctuations in fluorescence intensity. From the correlation in time, we can find the res-idence time, the number of chromophores, the volume in which they are diffusing andtherefore the fluorescence emission efficiency. Fluorescence properties are a probe ofthe local environment, a particularly powerful tool due to the high brightness (quantumyield) fluorescent dyes and sensitive photo-detection equipment both of which are readilyavailable, (such as avalanche photodiodes and photomultiplier tubes). Novel materialscombining the properties of conducting and non-conducting materials at scales muchsmaller than the incident wavelength are known as meta-materials. These allow combi-nations of properties not usually possible in natural materials at optical frequencies. Theproperties reported so far include; negative refraction, negative phase velocity, fluorescenceemission enhancement, lensing and therefore light confinement has also been proposed tobe possible. Instead of expensive and slow lithography methods many of these materialsmay be fabricated with self assembly techniques, which are truly nanoscopic and otherwiseinaccessible with even the most sophisticated equipment. It was found that nanoscaled volumes from ZMW and HMMs based on NW arrays wereall inefficient at enhancing fluorescence. The primary cause was the reduced fluorescencelifetime reducing the fluorescence efficiency, which runs contrary to some commentatorsin the literature. NW based lensing was found to possible in the blue region of the opticalspectrum in a HMM, without the background fluorescence normally associated with a PAAtemplate. This was achieved using a pseudo-ordered array of relatively large nanowireswith a period just smaller than lambda / 2 which minimised losses. Nanowires in the traditionalregime lambda / 10 produced significant scattering and lead to diffraction, such that they werewholly unsuitable for an optical lensing application.

Full text
Abstract:
Despite the demonstrated efficacy of psychotherapy in the treatment of a variety of psychological difficulties, a persistent problem is resistance to and noncompliance with that treatment. Cognitive-Behavioral therapists theorize that clients' negative beliefs and attitudes about the effectiveness of treatment, their ability to complete therapeutic assignments, and so on, are primary underlying causes of noncompliance. This dissertation tested this model. Twenty-eight individuals experiencing high levels of perceived stress completed a six week stress management training course. Measures of stress, beliefs about making changes, and compliance with treatment directives were made at regular intervals. The statistical technique called mediational analysis was used to test a causal linkage from negative attitudes and beliefs to treatment compliance, and from compliance to outcome. Although participants' mean levels of stress and distress showed significant reductions, there was little support for the proposed beliefs-compliance-outcome model. Alternative explanations for these results were considered. Support was expressed for continued development of the Negative Beliefs about Changing measure.

Full text
Abstract:
The hopelessness theory of depression (Abramson et al. 1989) considers hopelessness to be a subtype of depression. A causal chain is proposed which starts with the perceived occurrence of a negative life event, at which point inferences can be made about (i) why the event occurred, (ii) its consequences and (iii) characteristics about the self. In particular, the hopelessness theory predicts that: (a) each cognitive diathesis will interact with subsequent stress to produce symptoms of hopelessness depression (diathesis x stress component); (b) each causal factor in the model still contribute to the next in a proximal direction (causal mediation component). This thesis presents four studies examining the main predictions of hopelessness theory. Studies 1 and 2 utilised student samples (n=100) and cross-sectional designs. In Study 1, the role of the three sets of inferences was examined using hypothetical events. Some support was found for both the diathesis x stress and the causal mediation components. In Study 2 inferences for real events were considered. The results provided minimal support for the diathesis x stress component, and no support for the causal mediation component. In Study 3, the main predictions were tested more fully using prospective measurement in a 5-week follow-up of students (n=100). The diathesis x stress component was not supported and the causal mediation component received only partial support. In Study 4 the utility of the hopelessness theory in predicting post-natal depression was examined among a sample of primiparous women (n=172). Measures were taken during the third trimester of pregnancy, and at 4 and 12 weeks postpartum. Little evidence was found to support the diathesis x stress component. However, considerable support was found for the causal mediation component. Overall, the four studies produced contradictory evidence for the hopelessness theory. Implications for future research on the hopelessness theory of depression are discussed.

Abstract:
Gay and bisexual men in the United States and South Korea have some of the highest HIV rates in their countries, and both have the fewest sex education programs and policies for gay and bisexual males in secondary and postsecondary school systems. Consequently, many South Koreans do not view HIV as a South Korean problem, and with American gay and bisexual men living in this type of environment, their HIV sexual protection knowledge and practices may be compromised. The purpose of this study was to gain more understanding and insight into the sex education experiences and sexual practices of gay and bisexual American men living in a large city in South Korea, to determine how they perceived their sex education experiences from the American school system. The theoretical framework was based on Husserl and Heidegger's theory of intentionality. A phenomenological method was employed, utilizing a purposeful and criterion sample of 6 gay and bisexual American men who experienced sex education in the American school system and reported testing HIV negative on their last HIV tests. Data were analyzed and coded to identify categories and themes. The findings revealed that the participants who experienced heterosexual-focused sex education did not find it useful to them as gay men. The implications of these findings for positive social change are to inform policy makers and education leaders of how gay and bisexual American men perceived their sex education experiences and of the value of providing diverse, comprehensive sex education in the school system as it relates to knowledge about HIV and HIV prevention, not only for gay and bisexual males but for all American students as a tool to reduce or prevent new HIV cases.

Full text
Abstract:
Extracting meaningful information from large collections of text data is problematic because of the sheer size of the database. However, automated analytic methods capable of processing such data have emerged. These methods, collectively called text mining first began to appear in 1988. A number of additional text mining methods quickly developed in independent research silos with each based on unique mathematical algorithms. How good each of these methods are at analyzing text is unclear. Method development typically evolves from some research silo centric requirement with the success of the method measured by a custom requirement-based metric. Results of the new method are then compared to another method that was similarly developed. The proposed research introduces an experimentally designed testing method to text mining that eliminates research silo bias and simultaneously evaluates methods from all of the major context-region text mining method families. The proposed research method follows a random block factorial design with two treatments consisting of three and five levels (RBF-35) with repeated measures. Contribution of the research is threefold. First, the users perceived a difference in the effectiveness of the various methods. Second, while still not clear, there are characteristics with in the text collection that affect the algorithms ability to extract meaningful results. Third, this research develops an experimental design process for testing the algorithms that is adaptable into other areas of software development and algorithm testing. This design eliminates the bias based practices historically employed by algorithm developers.

Abstract:
Laboratory confirmation of HIV infection is primarily through the detection of HIV antibodies in an individual. Using the current immunoassays and confirmatory testing, false-positive results are exceedingly rare. However, providers should use clinical judgment when interpreting test results and consider additional follow-up testing when appropriate. False-negative immunoassays are also exceedingly rare except for individuals who are early in their infection and have yet to produce HIV antibodies that are detectable by current assays. Rapid HIV tests have similar testing accuracies as compared to those of currently available immunoassays and can be useful testing options for settings such as health fairs, nonclinical locations, and other situations in which quickly receiving preliminary test results would be beneficial.

Full text
Abstract:
Assessing Negative Response Bias in Competency to Stand Trial Evaluations provides a comprehensive guide to assessing malingering, feigning, poor effort, and lack of cooperation in competency to stand trial (CST) examinations. It draws on both the author’s extensive experience as a CST examiner and the vast, dynamic professional literature from forensic psychology, clinical psychology, and neuropsychology on assessing response style. The assessment process is considered from beginning to report writing and testimony, with tips regarding interview strategies, fact patterns and behaviors suggestive of feigning, testing, and creative and ethical use of collateral data. Every major validity test used by CST examiners is thoroughly and critically reviewed, as are others that are promising and not yet widely adopted. This includes self-report inventories such as the MMPI-2, MMPI-2-RF, PAI, and SIMS; structured interviews like the SIRS, SIRS-2, and M-FAST; performance validity tests like the TOMM, VIP, 15 item Test, and WMT; and CST-specific tests like the ILK and ECST-R Atypical Presentation Scales. A complete chapter is devoted to means to summarize and combine data from different tests and sources, and another to special populations such as defendants who claim amnesia, are intellectually disabled, or are adolescents. Report writing and testimony considerations are discussed in detail, with implications for the assessment and practice. In Chapter 10, CST examiners’ practices, including preferences for tests and collateral sources, are reported along with the perceived prevalence of various invalid presentation styles. Finally, policy implications of feigning and suggestions for cost-effective practice are provided.

Abstract:
The pipeline industry is improving its ability to detect and locate leaks through emerging technologies. There has been a variety of research in recent years aimed at further development of sensor-based technologies for leak detection. A key obstacle to retrofitting existing pipelines with leak detection technologies is the cost and risk of installing hardware, particularly those sensors that require excavation near the pipe. There are many advantages to employing leak detection systems that can leverage existing instrumentation access locations. One such technology may be negative-wave leak detection systems. Negative-wave technologies work by measuring dynamic pressure changes in the pipe. It should be noted that some negative-wave systems require line modifications to accommodate multiple transmitters. While such systems have been on the market for many years, there is insufficient data available about their performance under various pipeline operating conditions for widespread adoption. In an effort to close many information gaps on the performance envelope of negative-wave technologies, a PRCI-funded field test was performed on a 41-kilometer segment of a 30-inch diameter heavy crude oil pipeline. Products from three suppliers were installed at either end of the test segment. Actual commodity withdrawals were conducted at a remote valve site approximately 21 kilometers into the segment during various operations to test the systems’ abilities to detect the withdrawals without direct user interaction. These test points included withdrawals during steady-state flowing, pump startup, and shutdown conditions. Data were collected from each system to determine their abilities to detect leaks under various conditions, abilities to locate the leak, false alarm rates, and response times. This test provided significant insight into the performance of such systems over the range of conditions tested. The key focus of this paper is the approach for conducting such multi-vendor commodity withdrawals. This project required some unique considerations for its execution. Such considerations are also documented to provide input to others who are considering such a test.

Abstract:
While many people get HIV-related counseling and testing, only those who receive pre- and post-test counseling, and test voluntarily, are participating in voluntary counseling and testing (VCT). The high rates of HIV infection among youth make it crucial to find programs to prevent infection. Because there is evidence that many adults benefit from VCT, there is increasing interest in extending these services to young people. VCT counseling helps adolescents evaluate their own behavior and its consequences. A negative test result offers the opportunity to recognize vulnerabilities and develop risk-reduction plans to adopt safe behaviors. Young people who test HIV-positive can receive referrals for care and have opportunities to discuss and understand what their HIV status means and what responsibilities they have to themselves and others as a result. Young women who are pregnant and test HIV-positive should be offered special care to safeguard their own health and minimize the risk of passing the virus to the baby. This report assesses the available evidence about the current status of VCT and youth in developing countries.

Abstract:
The paper examines the effects of nonpharmaceutical interventions on transmission of the novel coronavirus disease (COVID-19) as captured by its reproduction rate 𝑅t. Using cross-country panel data, the paper finds that while lockdown measures have strong effects on 𝑅t, gathering bans appear to be more effective than workplace and school closures. Ramping up the testing and tracing of COVID-19 cases is found to be especially effective in controlling the spread of the disease where there is greater coverage of paid sick leave benefits. Workplace and school closures are found to have large negative effects on gross domestic product compared with other measures, suggesting that a more targeted approach can be taken to keep the epidemic controlled at lower cost.
