Developing a Validity Argument Through Abductive Reasoning with an Empirical Demonstration of the Latent Class Analysis

This article proposes and demonstrates a methodology for test score validation through abductive reasoning. It describes how abductive reasoning can be utilized in support of the claims made about test score validity. This methodology is demonstrated with a real data example of the Canadian English Language Proficiency Index Program (CELPIP)-General test—a program assessing functional English language ability in the community and workplace. Abductive reasoning seeks the enabling conditions through which a claim about a person's ability makes sense. For example, it makes sense that a person has strong functional language proficiency if he or she has been regularly using English to write emails and meet with colleagues at work. A valid test score should be affected by the extent of a person's engagement with such enabling conditions. Empirical evidence that warrants such an abductively reasoned claim is illustrated through a latent class analysis within a structural equation model. Evidence is examined to investigate whether certain classes of test takers who have been differentially engaging in the enabling conditions do, in fact, predict a person's CELPIP-General performance. The steps of the methodology are summarized in the closing section.     

Yearning and Its Measurement in Complicated Grief

Persistent intense yearning for the deceased is a core clinical feature of complicated grief (CG) that distinguishes it from other mental disorders that develop following loss. The Yearning in Situations of Loss Scale (YSL) is a recently developed assessment of yearning. To assess the psychometric properties of the YSL in those with CG, we administered the YSL, Inventory of Complicated Grief, and Quick Inventory of Depression Symptomatology to 303 treatment-seeking bereaved adults with CG. Our results suggest the YSL is a reliable assessment with acceptable convergent and discriminant validity as a measure of yearning in those with CG.     

Distinguishing the Ratio Bias from Unsystematic Error: Situation and Individual‐difference Effects

People often perceive the occurrence of events to be less likely when the likelihood of the event is expressed in ratios consisting of smaller numbers versus larger numbers, an effect known as the ratio bias. This work presents a theoretical framework for the conditions that need to be met for the ratio bias to occur. In doing so, we contrast effects on the ratio bias to those on unsystematic error, which have often been confounded in previous research. We find that the ratio bias is weaker (1) when both sets of numbers are relatively large than when both sets of numbers are relatively small; (2) for scenarios involving lottery tickets than for scenarios involving drawing balls from a bin; and (3) when a physical display depicting the numbers is provided to participants. Each of these factors reduced the ratio bias without reducing unsystematic error. Additionally, we show that unsystematic error is lower among people who (1) reason on the basis of proportions rather than on the basis of the numerator and denominator individually; (2) score higher on the rational scale of the Rational–Experiential Inventory; and (3) are of higher numeracy. We use these results to distinguish causes of error generally from those on the ratio bias specifically and discuss the implications for our understanding of when the ratio bias occurs.

Engaging and disengaging work conditions, momentary experiences and cortisol response

There is a growing literature suggesting important associations between the perceived work situation, individual health, and organizational outcomes. Less research has investigated employee experiences in the moment, which might help explain why the broader outcomes emerge. We examined momentary affect and cortisol from a within-day and between-day perspective, comparing working time to nonworking time for employees in engaging and disengaging workplaces. Findings indicate significantly lower momentary happiness and interest and higher stress and sadness are associated with work, and, in particular, with disengaging work environments. The connections between momentary affect and cortisol confirmed prior research, but cortisol was higher during non-work weekday moments. Employees with engaging work conditions had lower cortisol during weekday (working) mornings in comparison to employees with disengaging work conditions. There was no difference on Saturdays. These results provide evidence that work, and especially the work situation, is associated with affective and physiological momentary states.     

Effect of Nb on nanoquasicrystalline Al-based alloys

Nanoquasicrystalline Al-based alloys, containing icosahedral particles in an α-Al matrix, exhibit high strength at elevated temperature. The metastability of the quasicrystals can limit the use of these alloys. In the present work, the microstructural evolution of Al₉₃(Fe₃Cr₂)₇ and Al₉₃Fe₃Cr₂Nb₂ (at%) alloys was studied using heat treatments and structural characterization by XRD, TEM and STEM-EDX analysis. It was observed that the Nb is dissolved in the Al–Fe–Cr icosahedral phase. This provides higher thermal stability, retaining the fine nanoquasicrystalline microstructure for longer times at high temperature.     

The Romantic Absolute

In this article I argue that the Early German Romantics understand the absolute, or being, to be an infinite whole encompassing all the things of the world and all their causal relations. The Romantics argue that we strive endlessly to know this whole but only acquire an expanding, increasingly systematic body of knowledge about finite things, a system of knowledge which can never be completed. We strive to know the whole, the Romantics claim, because we have an original feeling of it that motivates our striving. I then examine two different Romantic accounts of this feeling. The first, given by Novalis, is that feeling gives us a kind of access to the absolute which logically precedes any conceptualisation. I argue that this account is problematic and that a second account, offered by Friedrich Schlegel, is preferable. On this account, we feel the absolute in that we intuit it aesthetically in certain natural phenomena. This form of intuition is partly cognitive and partly non-cognitive, and therefore it motivates us to strive to convert our intuition into full knowledge.     

Second-Order Change in Marriage and Family Therapy: A Web-Based Modified Delphi Study

Second-order change is a central concept in Marriage and Family Therapy, but still remains poorly operationalized. We conducted a web-based modified Delphi study with 31 established faculty members currently teaching in COAMFTE-accredited Master's and Doctoral programs in the United States and in Canada to identify consensus regarding second-order change concepts, clinical operationalization, evaluation, and teaching principles. Numerous exemplars of first and second-order change were generated, but consensus on most items was low. Consensus was highest for pedagogy and low regarding concepts and clinical examples of first-order change and evaluation of second-order change. Results suggest clearer definitions and better measurement of systemic change are needed.     

Marital event appraisals and frequencies: A comparison of distressed and nondistressed husbands

Abstract

Frequencies of marital events have been shown to vary according to whether a marriage is classified as distressed or nondistressed, but it is not known if these two groups of subjects appraise or view marital events in the same ways. This study examined husbands' appraisals of five marital events which were recorded daily for 90 consecutive days. Subjects appraised events according to four qualities: desirability, changingness, meaningfulness, and control. Event frequencies of desirable and undesirable events replicated previous work, but contrary to our expectations, there were no differences in how husbands from distressed and nondistressed marriages viewed events.
