title: Conducting External Profile Analysis with Multiple Regression
Creators: name: Culpepper, Steven Andrew
Publisher: name: University of Massachusetts Amherst
Year: 2008

description: Internal profile analysis methods that employ multidimensional scaling or cluster analysis continue to receive application in educational and psychological research. One critique of these methods is that there is no guarantee that the identified profiles will exhibit criterion or diagnostic validity. Recently, an external profile analysis technique was developed using multiple regression. The external profile analysis method yields a profile that is derived to explicitly relate to a criterion. This paper introduces the new external profile analysis method and presents an application that uses 8th grade NAEP reading test scores as the criterion and background questions pertaining to students’ out-of-school reading and writing behaviors and experiences as predictors. The external profile analysis sought to uncover a type or pattern of out-of-school experiences that related to reading achievement. The profile analysis findings were also used to interpret group performance differences and to identify possible recommendations for closing the male reading achievement gap.

description: We show that there is no algorithm deciding whether the maximal residually free quotient of a given finitely presented group is finitely presentable or not. Given a finitely generated subgroup G of a finite product of limit groups, we discuss the possibility of finding an explicit set of defining equations (i.e. of expressing G as the maximal residually free quotient of an explicit finitely presented group).

title: What Does it Mean to Be Average? The Miles per Gallon versus Gallons per Mile Paradox Revisited
Creators: name: Haans, Antal
Publisher: name: University of Massachusetts Amherst
Year: 2008

description: In the efficiency paradox, which was introduced by Hand (1994; J R Stat Soc A, 157, 317-356), two groups of engineers are in disagreement about the average fuel efficiency of a set of cars. One group measured efficiency on a miles per gallon scale, the other on a gallons per mile scale. In the present paper, I argue against an operationalistic explanation of the efficiency paradox, by showing that the paradox is neither the result of an ambiguously defined efficiency concept, nor the result of how fuel efficiency is measured (i.e., whether a miles per gallon, or gallons per mile scale is used). The actual paradox is that the two groups of engineers have asked different statistical questions, while using the same mathematical operation. The paradox results from the fact that fuel efficiency is a derived measure, like density and speed, for which end-to-end concatenation (i.e., addition) is not straightforward.

description: Generic model predictions for the early neutrino signal of a core-collapse supernova (SN) imply that IceCube can reconstruct the bounce to within about +/- 3.5 ms at 95% CL (assumed SN distance 10 kpc), relevant for coincidence with gravitational-wave detectors. The timing uncertainty scales approximately with distance-squared. The offset between true and reconstructed bounce time of up to several ms depends on the neutrino flavor oscillation scenario. Our work extends the recent study of Pagliaroli et al. [PRL 103, 031102 (2009)] and demonstrates IceCube's superb timing capabilities for neutrinos from the next nearby SN.

title: An Illustration of a Mantel-Haenszel Procedure to Flag Misbehaving Common Items in Test Equating
Creators: name: Michaelides, Michalis P.
Publisher: name: University of Massachusetts Amherst
Year: 2008

description: In this study the Mantel-Haenszel procedure, widely used in studies for identifying differential item functioning, is proposed as an alternative to the delta-plot method and applied in a test-equating context for flagging common items that behave differentially across cohorts of examinees. The Mantel-Haenszel procedure has the advantage of conditioning on ability when making comparisons of performance of two examinee groups on an item. There are schemes for interpreting the effect size of differential performance, which can inform the decision as to whether to retain those items in the common-item pool, or to discard them. Data from a statewide assessment are analyzed to illustrate the use of this procedure. Advantages of this methodology are discussed and limitations regarding test design that may make its application difficult are described.

title: Revisiting the Collinear Data Problem: An Assessment of Estimator 'Ill-Conditioning' in Linear Regression
Creators: name: Callaghan, Karen J.
Publisher: name: University of Massachusetts Amherst
Year: 2008

description: Linear regression has gained widespread popularity in the social sciences. However, many applications of linear regression have been in situations in which the model data are collinear or ‘ill-conditioned.’ Collinearity renders regression estimates with inflated standard errors. In this paper, we present a method for precisely identifying coefficient estimates that are ill-conditioned, as well as those that are not involved, or only marginally involved in a linear dependency. Diagnostic tools are presented for a hypothetical regression model with ordinary least squares (OLS). It is hoped that practicing researchers will more readily incorporate these diagnostics into their analyses. Accessed 17,081 times on https://pareonline.net from June 18, 2008 to December 31, 2019.

description: The paper presents a rubric to help evaluate the quality of research projects. The rubric was applied in a competition across a variety of disciplines during a two-day research symposium at one institution in the southwest region of the United States of America. It was collaboratively designed by a faculty committee at the institution and was administered to 204 undergraduate, master, and doctoral oral presentations by approximately 167 different evaluators. No training or norming of the rubric was given to 147 of the evaluators prior to the competition. The findings of the inter-rater reliability analysis reveal substantial agreement among the judges, which contradicts literature describing the fact that formal norming must occur prior to seeing substantial levels of inter-rater reliability. By presenting the rubric along with the methodology used in its design and evaluation, it is hoped that others will find this to be a useful tool for evaluating documents and for teaching research methods.

The mechanism of permanganate oxidations : pivalaldehyde, benzaldehyde and p-nitro-phenyltrifluoromethylcarbinol.
Creators: name: Fleming, Donald George
Publisher: name: University of British Columbia
Year: 2011

description: A study has been made of the potassium permanganate oxidation of three organic compounds: pivalaldehyde, p-nitrobenzaldehyde and p-nitrophenyltrifluoromethyl-carbinol. The permanganate-pivalaldehyde reaction has been investigated in the pH range 1 to 13. The results show that the reaction is first order in permanganate and aldehyde, that the oxidation by manganate is slower than that of permanganate by a factor of twenty five, and that the oxidation is general acid-catalyzed. The results in alkaline solution show some increase in rate but are not reproducible, which is most likely due to radical decomposition of the pivalaldehyde. Three mechanisms are discussed: Firstly, a typical general acid-catalysis scheme, secondly, one involving a tetragonal transition state and thirdly, one based on a hydride transfer. Of these, only the first two are able to accommodate the experimental evidence found earlier in the permanganate oxidation of benzaldehyde by Wiberg and Stewart (1). The autocatalysis exhibited by the permanganate benzaldehyde reaction has been studied at low pH. The autocatalysis has also been investigated with p-nitrobenzaldehyde in order to see if there is any substituent effect. Results show that the p-nitro aldehyde has a longer induction period. Moreover, it has been shown that overoxidation of the benzene ring rather than true autocatalysis has occurred. A radical chain mechanism has been put forward in an attempt to explain this observation. The permanganate oxidation of p-nitrophenyltri-fluoromethylcarbinol has been studied in 0.1 M sodium hydroxide in order to determine the mechanism of the reaction. A large enhancement in rate observed compared to rates found by Stewart and Van der Linden (2) in the permanganate oxidation of other substituted phenyltrifluoromethylcarbinols is good evidence for a reaction path involving hydrogen atom abstraction from the alkoxide to the permanganate ion. Such a mechanism is consequently favoured.

description: Ethnic conflict in Fiji has been on the rise. The riots in Suva in September 1987 were racially motivated as were a number of criminal activities since then. The 1990 Fiji Constitution and the debate following the two coups of 1987 have brought the race issue to the forefront in a number of policy discussions in the country.1 The current debates over land tenure and the constitution are heavily flavoured with racial connotations. Despite the significance of race as an issue in Fiji, the local academia has paid little, if any, attention to race issues. One reason for this has been the political sensitivity of such discussions. Another is the fear of being labelled a ‘racist.’ Political correctness demands that one keep clear of discussions on race issues. This paper is sensitive to the above concerns but attempts to fill the vacuum of objective discussion on the race issue in Fiji. Politicians, the media, special interest groups, as well as the general public, have often discussed race issues—at times with immense heat and gross exaggeration. For example, race relations in Fiji have been compared to apartheid in South Africa. Although in relative terms Fiji is still a peaceful country, complacency is warned against, particularly in the current climate of deteriorating race relations. The view taken here is that the race issue has to be addressed objectively if social stability and economic prosperity are to be achieved in the near future.

description: Zur Risikoabsicherung und zur Vorbeugung von betrieblichen Liquiditätsengpässen werden häufig Absicherungsgeschäfte auf Wareterminmärkten empfohlen. Weniger Beachtung hat bislang die Möglichkeit der optimierten betrieblichen Planung bei Preisabsicherung durch Hedgegeschäfte gefunden. In dem vorliegenden Beitrag wird geprüft, ob Anpassungen der Anbauplanung bei Planungssicherheit durch Preisabsicherung zu höheren Deckungsbeiträgen führen können. Dazu wird die Fruchtfolge für einen schleswig-holsteinischen Beispielbetrieb unter Berücksichtigung von Vorfruchteffekten und der Auslastung von Maschinen und Arbeitskräften optimiert. Als Referenz dient eine Standardfruchtfolge aus Raps, Weizen und Gerste. Bei der Optimierung werden Szenarien mit und ohne Restriktionen der Greening-Vorgaben der EU berechnet. Die Ergebnisse zeigen, dass die Optimierung der Anbauplanung unter Preisabsicherung zu einer Erhöhung des Deckungsbeitrages um bis zu 3,7 Prozent gegenüber der Referenz führen kann.

description: Health economic analyses of novel technologies are useful for purchasing decisions and should consider adverse events if technologies demonstrate an improvement in safety. However, the costs associated with cataract surgery complications from a healthcare provider perspective are not well documented in the literature. This review discusses several cataract surgery complications that can potentially be impacted by novel technologies including posterior capsule rupture (PCR), corneal burn, cystoid macular edema (CME), corneal edema, and elevated intraocular pressure (IOP). Limitations of databases to identify these costs from a healthcare provider perspective are discussed. Estimates of the healthcare resources utilized for treating these cataract surgery complications and associated costs are presented, derived from discussions with an expert panel and published literature, where available. There is a current gap in the literature with respect to the costs of cataract surgery complications to US healthcare providers. Estimates from this paper can provide insight into complications and associated costs that could be considered in future economic analyses of technologies designed to reduce cataract surgery complications. Those results in turn can inform healthcare resource planning and allocation decisions.

description: When testlet effects and item idiosyncratic features are both considered to be the reasons of DIF in educational tests using testlets (Wainer & Kiely, 1987) or item bundles (Rosenbaum, 1988), it is interesting to investigate the phenomena of DIF amplification and cancellation due to the interactive effects of these two factors. This research applies the multiple-group testlet item response theory model developed by Li et al. (2006) to examine in detail different situations of DIF amplification and cancellation at the item and testlet level using testlet characteristic curve procedures with signed/unsigned area indices and logistic regression.

description: The sources and degradation profiles of dissolved environmental RNAs from fish in water remain unknown. In this study, laboratory experiments and mathematical modelling were conducted to investigate the permeability of RNA extracted from zebrafish cells through filters, the release of dissolved environmental RNAs from live and dying zebrafish cells, and the degradation of RNA extracted from zebrafish cells in a non-sterile aqueous environment. This research aimed to provide biological and ecological insights into fish RNAs dissolved in water. The results showed that most of the RNA extracted from zebrafish cells was detected in the filtrates after passage through 0.45 µm filters. Over the course of the 6-day experiment, dynamic levels of the RNAs in the liquid environment containing live or dying zebrafish cells were determined. The release and degradation rates of dissolved environmental RNA from zebrafish cells were calculated using mathematical modelling. RNA extracted from zebrafish cells degraded in non-sterile water in the tubes, and after 2 months, more than 15% of the RNAs in the water remained detectable. The half-life of the RNA in the tubes was approximately 20 ~ 43 days. The modelling results suggest that the levels of the dissolved environmental fish RNAs in natural waters or aquariums could be so low that it would be difficult to detect them using current techniques. The results obtained in this study will help develop new methods for measuring the dynamics of dissolved environmental fish RNAs in water and determining their significance.

description: When attempting to determine if an intervention has a causal impact, the â€˜gold standardâ€™ of program evaluation.is the randomized controlled trial (RCT). In education studies random assignment is rarely feasible at the.student level, making RCTs harder to conduct. School-level assignment is more common but this often.requires considerable resources compared to designs where classrooms can be assigned within a school. This.article describes the costs and benefits of testing the effects of a classroom based instructional intervention.using the multi-site cluster RCT. Topics covered include a discussion of various design options, statistical.power, contamination, prior evidence, generalizability of results, ease of recruitment and need for data.collection. The purpose of the article is to inform practice by providing program evaluators with an in-depth.look at various RCT design options that were considered when searching for a way to efficiently evaluate a.school-based intervention.

The system presented here is a vision-based system for detection of long voluntary eye blinks and interpretation of blink patterns for communication between man and machine. This system replaces the mouse with the human face as a new way to interact with the computer. Facial features (nose tip and eyes) are detected and tracked in realtime to use their actions as mouse events. The coordinates and movement of the nose tip in the live video feed are translated to become the coordinates and movement of the mouse pointer on the application. The left or right eye blinks fire left or right mouse click events. The system works with inexpensive USB cameras and runs at a frame rate of 30 frames per second.

Some reactions of tetramethyldiarsine and related compounds

description: Tetramethyldiarsine Is found to add across the double bond of fluoroölefins of the type CF₂=CFX (X = F,Cl,Br), to give addition products. Thus 1:1 adducts, i.e. (CH₃)₂As-CF₂-CFX-As(CH₃)₂, are obtained in the reactions of tetramethyldiarsine and CF₂=CFX (X = CI,Br). The reaction of tetramethyldiarsine and tetrafluoroethylene, however, gives (CH₃)₂Aa-(CF₂-CF₂)₄-As(CH₃)₂, a 1:4 adduct. Iodotrifluoroethylene and tetramethyldiarsine react to give an adduct which Is unstable in air, but this reaction yields dimethylperfluorovinylarsine, b.p. 71°. The above arsine is also prepared by the reaction of iododimethylarsine and iodotrifluoroethylene in the presence of mercury. Tetramethyldiarsine does not react with ethylene at 20°. Bromotrifluoroethylene does not give an addition product with tetrakis(trifluoromethyl) diarsine. Hexafluoro-2-butyne reacts with tetramethyldiarsine at 20° to yield a 1:1 adduct, trans-1,2-bis(dimethylarsino)-1,2-bis(trIfluoromethyl)ethylene. Tetrakis (trifluoromethyl)diarsine and arsenobenzene do not react with hexafluoro-2—butyne to give adducts. Iodotrifluoromethane reacts with arsenobenzene to produce iodophenyltrifluoromethylarsine, phenylbis(trifluoromethyl) arsine and phenyIdliodoarsine. The mechanism of this reaction has been suggested. The iodophenyltrifluoromethylarsine reacts with silver chloride to yield chlorophenyltrifluoromethylarsine. The chloroarsine and bis(trifluoromethyl)arsine react with the elimination of hydrogen chloride to form a diarsine, which Is believed to be the symmetrical 1,2-bis(phenyl)-!, 2-bis (trifluoromethyl) diarsine. This same diarsine is probably formed by the coupling of two iodophenyltrifluoromethylarsine molecules in the presence of mercury. Paranitroarsenobenzene reacts with iodotrifluoromethane with explosive violence. Trimethylarsine does not undergo exchange reaction with bromotrifluoroethylene to give dimethylperfluorovinylarsine. Hexafluoro-2-butyne does not give an addition compound with iodo- dimethylarsine. Tetrakis(trifluoromethyl)diphosphine fails to yield adduct with bromotrifluoroethylene at 120°. Hexafluoro-2-butyne also does not give adducts with tetrakis(trifluoromethyl)diphosphine, hexa-phenylditin and hexabutylditin.

description: Before the mid 20th century most scientific writing was solely authored (Claxton, 2005; Greene, 2007) and thus it is only relatively recently, as science has grown more complex, that the ethical and procedural issues around authorship have arisen. Fields as diverse as medicine (International Committee of Medical Journal Editors, 2008), mathematics (e.g., American Statistical Association, 1999), the physical sciences (e.g., American Chemical Society, 2006), and the social sciences (e.g., American Psychological Association, 2002) have, in recent years, wrestled with what constitutes authorship and how to eliminate problematic practices such as honorary authorship and ghost authorship (e.g., Anonymous, 2004; Claxton, 2005; Manton & English, 2008). As authorship is the coin of the realm in academia (Louis, Holdsworth, Anderson, & Campbell, 2008), it is an ethical issue of singular importance. The goal of this paper is to review prominent and diverse guidelines concerning scientific authorship and to attempt to synthesize existing guidelines into recommendations that represent ethical practices for ensuring credit where (and only where) credit is due.

description: Material failure by crack propagation essentially involves a concentration of large displacement-gradients near a crack's tip, even at scales where no irreversible deformation and energy dissipation occurs. This physical situation provides the motivation for a systematic gradient expansion of general nonlinear elastic constitutive laws that goes beyond the first order displacement-gradient expansion that is the basis for linear elastic fracture mechanics (LEFM). A weakly nonlinear fracture mechanics theory was recently developed by considering displacement-gradients up to second order. The theory predicts that, at scales within a dynamic lengthscale $\ell$ from a crack's tip, significant $\log{r}$ displacements and $1/r$ displacement-gradient contributions arise. Whereas in LEFM the $1/r$ singularity generates an unbalanced force and must be discarded, we show that this singularity not only exists but is {\em necessary} in the weakly nonlinear theory. The theory generates no spurious forces and is consistent with the notion of the autonomy of the near-tip nonlinear region. The J-integral in the weakly nonlinear theory is also shown to be path-independent, taking the same value as the linear elastic J-integral. Thus, the weakly nonlinear theory retains the key tenets of fracture mechanics, while providing excellent quantitative agreement with measurements near the tip of single propagating cracks. As $\ell$ is consistent with lengthscales that appear in crack tip instabilities, we suggest that this theory may serve as a promising starting point for resolving open questions in fracture dynamics.

The presented evaluation investigates: (1) the classification accuracy of tests scored using decision theory; (2) the effectiveness of different sequential testing procedures; and (3) the number of items needed to make a classification. A large percentage of examinees can be classified accurately with very few items using decision theory.

description: We present a systematic performance analysis of first-principles basin-hopping (BH) runs, with the target to identify all low-energy isomers of small Si and Cu clusters described within density-functional theory. As representative and widely employed move classes we focus on single-particle and collective moves, in which one or all atoms in the cluster at once are displaced in a random direction by some prescribed move distance, respectively. The analysis provides detailed insights into the bottlenecks and governing factors for the sampling efficiency, as well as simple rules-of-thumb for near-optimum move settings, that are intriguingly independent of the distinctly different chemistry of Si and Cu. At corresponding settings, the observed performance of the BH algorithm employing two simple, general-purpose move classes is already very good, and for the small systems studied essentially limited by frequent revisits to a few dominant isomers.

description: This study investigated the impact of the coding scheme on IRT-based true score equating under a.common-item nonequivalent groups design. Two different coding schemes under investigation were carried out.by assigning either a zero or a blank to a missing item response in the equating data. The investigation involved.a comparison study using actual large scale data and then Monte Carlo simulations for a systematic inspection on.the topic. The recommendations on the basis of the findings of the study were made to treat omitted responses.as not-administered rather than as wrong, and use a large sample size to ensure the accuracy of the screening.tools such as the displacement index and the robust-z statistic during equating.

description: Approximately 10% of individuals with multiple sclerosis (MS) have pediatric-onset (<18-years-old). Pediatric-specific barriers to accessing disease modifying therapies (DMT) exist. Issues include few pediatric-based randomized controlled trials (RCT), often required for formal regulatory approval, and resultant challenges with cost/coverage. This review assessed real-world DMT uptake in pediatric-MS to better understand potential barriers. We performed a scoping review of observational studies examining DMTs in patients with pediatric-MS published between 07/1993 and 06/2024. PRISMA guidelines were used. Databases searched included: Cochrane Library, Ovid MEDLINE/Embase, Scopus, and Web of Science. Studies must include >10 DMT exposed pediatric-MS patients with full-text available in English. RCTs/pharmaceutical-industry funded studies were excluded. Of 2114 abstracts screened, 88 studies were included. A total of 21,591 patients (13,411 females) were included. DMTs were used in 68.7% (n = 14,833). Most studies were from Europe (53.4%), North America (22.7%), or the Middle East (10%). Regional variabilities were found in DMT uptake between continents. Only 13 (14.8%) studies included information on DMT funding source. Pediatric-MS patients showed low DMT uptake with variability in DMT use based on region. Limited data was found regarding specific barriers to DMT access. Further research is needed to better understand regional barriers to access.

description: In clinical practice, cardiovascular and renal safety profiles of sacubitril/valsartan, compared with those of valsartan alone, remain controversial. Therefore, we aimed to compare the pharmacovigilance signals related to cardiovascular and renal adverse events between sacubitril/valsartan and valsartan alone using the Food and Drug Administration Adverse Event Reporting System (FAERS) database. Raw report data on cardiac and renal adverse events associated with sacubitril/valsartan and valsartan alone were retrieved from the FAERS database using preferred terms from the Medical Dictionary for Regulatory Activities. Preferred terms were mapped to System Organ Classes, and the time to onset of adverse events associated with sacubitril/valsartan and valsartan alone was calculated. Most adverse events associated with sacubitril/valsartan occurred within the first month, whereas adverse events were more prevalent 6 months to 1 year after administration of valsartan alone. Adverse events reported for sacubitril/valsartan and valsartan alone included cardiac failure, cardiogenic shock, and ventricular fibrillation. Considering sacubitril/valsartan only, adverse events reported were renal impairment, renal failure, and acute kidney injury. For valsartan alone, adverse events reported included arrhythmia and angina pectoris. Sacubitril/valsartan carries a higher renal safety risk and lower cardiac safety risk than valsartan alone.

description: Given an ideal $I$ on $ω$ let $a(I) $ ($\bar{a}(I)$) be minimum of the cardinalities of infinite (uncountable) maximal $I$-almost disjoint subsets of $[ω]^ω$, and denote $b_I$ and$d_I$ the unbounding and dominating numbers of $(ω^ω,\le_I)$. We show that (1) $a(I)>omega$ if $I$ is a summable ideal; (2) $a(Z)=ω$ and $\bar{a}(Z)\le a$ if $Z$ is a tall density ideal, (3) $b\le \bar{a}(I)$, and $b_I=b$ and $d_I=d$, for any analytic P-ideal $I$ on $ω$. Given an analytic $P$-ideal $I$ we investigate the relationship between the Sack, the $I$-bounding, $I$-dominating and $ω^ω$-bounding properties of a given poset $P$. For example, for the density zero ideal $Z$ we can prove: (i) a poset $P$ is $Z$-bounding iff it has the Sacks property, (ii) if $P$ adds a slalom capturing all ground model reals then $P$ is $Z$-dominating.

description: While linear programming is a common tool in business and industry, there have not been many applications in educational assessment and only a handful of individuals have been actively involved in conducting psychometric research in this area. Perhaps this is due, at least in part, to the complexity of existing software packages. This article presents three applications of linear programming to automate test assembly using an add-in to Microsoft Excel 2007. These increasingly complex examples permit the reader to readily see and manipulate the programming objectives and constraints within a familiar modeling environment.

Creators: name:  Strang, Kenneth David
Publisher: name: University of Massachusetts Amherst

description: This paper discusses how a seldom-used statistical procedure, recursive regression (RR), can numerically and graphically illustrate data-driven nonlinear relationships and interaction of variables. This routine falls into the family of exploratory techniques, yet a few interesting features make it a valuable compliment to factor analysis and multiple linear regression for method triangulation. By comparison, nonlinear cluster analysis also generates graphical dendrograms to visually depict relationships, but RR (as implemented here) uses multiple combinations of nominal and interval predictors regressed on a categorical or ratio dependent variable. In similar fashion, multidimensional scaling, multiple discriminant analysis and conjoint analysis are constrained at best to predicting an ordinal dependent variable (as currently implemented in popular software). A flexible capability of RR (again as implemented here) is the transformation of factor data (for substituting codes). One powerful RR feature is the ability to treat missing data as a theoretically important predictor value (useful for survey questions that respondents do not wish to answer). For practitioners, the paper summarizes how this technique fits within the generally-accepted statistical methods. Popular software such as SPSS, SAS or LISREL can be used, while sample data can be imported in common formats including ASCII text, comma delimited, Excel XLS, and SPSS SAV. A tutorial approach is applied here using RR in LISREL. The tutorial leverages a partial sample from a study that used recursive regression to predict grades from international student learning styles. Some tutorial portions are technical, to improve the ambiguous RR literature. Accessed 17,736 times on https://pareonline.net from March 16, 2009 to December 31, 2019.
