Bringing DEI to the Forefront in University of Nebraska-Lincoln Libraries’ Collections

UNL Libraries’ recently released strategic plan codifies a longstanding organizational commitment to advancing principles of diversity, equity, and inclusion (DEI). Diversity of collections and equity of access are important components of the objectives articulated in this plan. This poster presents an overview of holistic efforts to incorporate considerations of DEI, as well as universal accessibility, into the mainstream of ongoing collection development and acquisition work at UNL Libraries. It covers topics including: the development of a set of guiding principles along with a diversity rubric for acquisitions; departmental reorganization; participation in consortial initiatives; optimizing use of support from Libraries\u27 administration; training and professional development; electronic resources accessibility; and support for Open Access publishing and infrastructure

Performance Evaluation of Judgmental Directional Exchange Rate Predictions

Cataloged from PDF version of article.A procedure is proposed for examining different aspects of performance for judgemental directional probability predictions of exchange rate movements. In particular, a range of new predictive performance measures is identified to highlight specific expressions of strengths and weaknesses in judgemental directional forecasts. Proposed performance qualifiers extend the existing accuracy measures, enabling detailed comparisons of probability forecasts with ex-post empirical probabilities that are derived from changes in the logarithms of the series. This provides a multi-faceted evaluation that is straightforward for practitioners to implement, while affording the flexibility of being used in situations where the time intervals between the predictions have variable lengths. The proposed procedure is illustrated via an application to a set of directional probability exchange rate forecasts for the US Dollar/Swiss Franc from 23/7/96 to 7/12/99 and the findings are discussed.

Fermat hypersurfaces and Subcanonical curves

We extend the classical Enriques-Petri Theorem to $s$-subcanonical projectively normal curves, proving that such a curve is $(s+2)$-gonal if and only if it is contained in a surface of minimal degree. Moreover, we show that any Fermat hypersurface of degree $s+2$ is apolar to an $s$-subcanonical $(s+2)$-gonal projectively normal curve, and vice versa.Comment: 18 pages; AMS-LaTe

Socioeconomic Status and Stress as Factors in Academic Dishonesty

A recent survey demonstrated that over 80% of students admitted to having engaged in academic dishonesty at least once in their time at University (Macaulay & Lemm, 2014). Previous research examining why students cheat has brought to light many different potential reasons behind students’ academically dishonest behavior (McCabe, Trevino, & Butterfield, 1999; Curasi, 2013). The present set of studies aimed to examine three potential factors behind why students engage in academic dishonesty. Study 1 examined whether or not high Socioeconomic Status (SES) primes would elicit higher cheating likelihood ratings in a hypothetical scenario. Study 2 examined whether high levels of academic stress and job pressure would increase participants’ cheating likelihood ratings. Further, Study 2 also examined whether participants would perceive a cheating action as less morally wrong when it was committed under academic stress or job pressure in comparison to no stress or pressure. Results indicated that SES priming had no effect on cheating likelihood. Both academic stress and job pressure predicted increased cheating likelihood ratings in different samples. The relation between academic stress and cheating likelihood ratings was mediated by moral appraisal. The results support the idea that justification of unethical behavior predicts increased cheating likelihood. Future research will focus on applying these results to prevention of academic dishonesty

Study of manufacturing and measurement reproducibility on a laser textured structured surface

In recent years there has been increasing interest in the use of structured surfaces to provide specific functional performance. Such surfaces often consist of localised micro-scale surface features with predetermined geometries. The performance of the feature manufacturing process affects the functional performance of the surface, and can be assessed by measurement of the resulting surface features. Measurement of the resulting micromanufactured surface features necessitates use of areal optical surface topography instruments. However, conventional characterisation methods, based on areal surface texture parameters, often prove inadequate, and may fail to capture the relevant geometric properties needed for an effective dimensional verification. This paper investigates an alternative route to verification, based on the determination of geometric attributes of the microfabricated features. This approach allows for direct assessment of manufacturing process performance, by comparison of the geometric attributes with their nominal values. An example application is shown in which a micromachining process (laser texturing) is used to fabricate a periodic pattern of dimples, which provide a low friction bearing surface. In this paper, manufacturing process performance is assessed by characterisation of the diameter and out-of-roundness. Sources of uncertainty associated with these geometric parameters are also considered

Evaluating predictive performance of judgemental extrapolations from simulated currency series

Cataloged from PDF version of article.Judgemental forecasting of exchange rates is critical for ®nancial decision-making. Detailed investigations of the potential e ects of time-series characteristics on judgemental currency forecasts demand the use of simulated series where the form of the signal and probability distribution of noise are known. The accuracy measures Mean Absolute Error (MAE) and Mean Squared Error (MSE) are frequently applied quantities in assessing judgemental predictive performance on actual exchange rate data. This paper illustrates that, in applying these measures to simulated series with Normally distributed noise, it may be desirable to use their expected values after standardising the noise variance. A method of calculating the expected values for the MAE and MSE is set out, and an application to ®nancial experts' judgemental currency forecasts is presented. Ó 1999 Elsevier Science B.V.

Physically Embodying the Oppressive Trinity: Engaging in Disruptive Identity Praxis as a White Middle Class Male

Abstract As an educator in multiple roles who embodies, what I contend is the oppressive trinity while working with individuals who possess identities vastly different than mine, I use this text discuss several practices and praxis that can disrupt the normative standard of American society. First, I discuss how capitalism, racism, and patriarchy operate not as autonomous and separate doctrines, but rather animate and give life to each other and thus should be thought of as one collective ideology as referred to as the oppressive trinity. Second, I discuss autoethnography as an experiential and narrative driven methodological approach incorporated in this analysis. This methodological approach is a unique stylistic and theoretical approach to research, which fuses theory and personal narrative together. Finally, I share a number of practices and praxis I have used to shred the veil obscuring my vision of how the oppressive trinity functions through its physical embodiment, material objects, cultural symbols, and social practices
