Do Hispanic and Asian Adolescents Practice Panethnicity in Friendship Choices?*

Objectives. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we investigate whether Asian and Latino youth value racial boundaries more than ethnic boundaries. We evaluate the relative preferences of same‐ethnic, same‐race (but different‐ethnic), and different‐race friends. Methods. We use multilevel multinomial logistic regression models to examine the odds of choosing same‐ethnic, different‐ethnic (but same‐race), and different‐race friends net of the opportunity to interact. Results. We find strong effects of school racial and ethnic composition, immigrant status, and parental education on the likelihood of crossing boundaries in the selection of friends. In addition, we develop a new scale of panethnicity and find substantial ethnic group variation in panethnic sentiment. Conclusion. We find an overwhelming preference for same‐ethnic peers over same‐race (different‐ethnic) and different‐race peers.     

A note on the rubustness of the lilliefors test for univariate normality with respect to equicorrelated data

The Lilliefors test, which was developed by Lilliefors (1967), is a well-known test for univariate normality when population parameters are unknown. The main assumption for implementing the test is the independent-data assumption. This paper demonstrates the robustness of the Lilliefors test against equicorrelated observations. More specifically, we show that the null distribution of the Lilliefors test statistic is invariant under the alternate assumption that the observations are equicorrelated.     

Some New Estimators for Small-Area Means With Application to the Assessment of Farmland Values

Regression models that account for main state effects and nested county effects are considered for the assessment of farmland values. Empirical predictors obtained by replacing the unknown variances in the formulas of the optimal predictors by maximum likelihood estimates are presented. The computations are carried out by simple iterations between two SAS procedures. Estimators for the prediction variances are derived, and a modification to secure the robustness of the predictors is proposed. The procedure is applied to data on nonirrigated cropland in the Corn Belt states and is shown to yield predictors with considerably lower prediction mean squared errors than the survey estimators and other regression-type estimators.     

Everyday discrimination,emotion, and daily interactions during adolescence

The present study examined whether everyday discrimination relates to the frequency of adolescents' positive and negative daily social interactions and whether these associations are driven by anger and positive emotion. Adolescents (N = 334) participated in a three-wave longitudinal study, in which they completed surveys regarding everyday discrimination, anger, and positive emotion, as well as 15 daily reports of conflict and getting along with friends and family. Higher everyday discrimination was related to more daily conflicts and fewer experiences of getting along with other people. Longitudinal models also provided preliminary evidence that everyday discrimination was associated with daily conflicts 4 years later indirectly through anger. Overall, results suggest everyday discrimination relates to adolescents' daily experiences, potentially through differences in emotion.     

CONCEPTUAL LEVELS AND THE DESIGN OF ACCOUNTING INFORMATION SYSTEMS*

This article attempts to expand and clarify the discussions in the literature on complexity theory applied to accounting via two central assertions: (a) affecting the cognitive conceptual level of an individual through the financial reporting system can be accomplished not only by varying the immediate information load, but also, in the long run, by modifying the types of information and the mode of user-system interface. In other words, a properly designed accounting information system can have developmental cognitive effects in both the short and long run. (b) attempting to maximize the conceptual level of the decision maker is not always desirable. In certain types of environments, a high conceptual level actually impedes appropriate decision making. Therefore, the appropriate conceptual level must be related to the type of decision being made as well as to the type of decision maker.     

Exploring racism inside and outside the mathematics classroom in two different contexts: Colombia and USA

We give attention to the racial contexts of mathematics education in Colombia and the USA. We discuss the particularities of these contexts but also explore the how in both contexts Blackness and Black people are relegated to the lower rungs of the social order. In offering this comparative analysis, we call for expanded research on race, racism, and mathematics education in global contexts.     

ARE THE DISABLED LESS LOSS AVERSE? EVIDENCE FROM A NATURAL POLICY EXPERIMENT

Research findings show that disabled persons often develop physical and psychological mechanisms to compensate for disabilities. Coping mechanisms may not be limited to the psychophysiological domain and may extend to cognitive bias and loss aversion. In this study, we apply unique microdata from a natural policy experiment to assess the role of loss aversion in home purchase among nondisabled and disabled households. Results of survival analysis indicate that the physically disabled are substantially less loss averse in home purchase. Furthermore, loss aversion varies with other population characteristics and attenuates with degree of disability. Findings provide new evidence of diminished cognitive bias and more rational economic decision‐making among the physically disabled. (JEL D03, C9, R38)     

Psychological Distress and Size of Place: The Epidemiology of Rural Economic Stress

Abstract Size-of-place differences in the distribution of psychological distress are examined. Residents in communities of less than 2,500 population are predicted to have higher levels of distress than persons living in farm, rural nonfarm, and larger places. A research instrument was designed to measure economic stress, personal resources, and psychological distress in a survey of adult householders in a midwestern state. Results support the interpretation that long-term demographic and social trends had a negative impact upon the psychological well-being of residents in rural communities. Residents of these rural communities have higher levels of distress than persons living on farms or in towns of up to 9,999 population. Levels of psychological distress are not significantly different between persons living in rural communities and those in small cities or urban centers.     

Social Meanings of the Occult*

Data from a participant-observational study of the tarot are used to explore the social meanings of modern occultism and to examine certain rival contentions about these beliefs, practices, adherents, and the manner in which activities are or are not organized socially. Unlike collective behavioral audiences, which employ occultisms as a form of popular entertainment, the occult practitioners reported here participate in an “esoteric community” involving practitioner-client relations, social networks, and small cult-like groups. Although the occult tarot constitutes an elaborate theosophy, contemporary adherents selectively subscribe to these doctrines and they freely mix the occult, other esoteric teachings, and elements of traditional culture. When the tarot is used in a divinatory fashion as a service to the general public for pay, problems of legitimacy commonly arise. Occultists in the community deal with this problem by presenting themselves as “professionals.” Within the nominally pluralistic climate of American society, occultisms thereby become another path to dealing meaningfully with life's problems and expressing individual identity. Organized in terms of loose collections of practitioners and groups and supported by the larger cultic milieu, occult communities represent an adaptation to modern society which is likely to persist long after particular groups fail or particular individuals move on to other social scenes.     

Optimal On-Line Scheduling of Parallel Jobs with Dependencies

We study the following general on-line scheduling problem. Paralleljobs arrive on a parallel machine dynamically according to thedependencies between them. Each job requests a certain number ofprocessors in a specific communication configuration, but its runningtime is not known until it is completed. We present optimal on-linealgorithms for PRAMs and one-dimensional meshes, and efficientalgorithms for hypercubes and general meshes. For PRAMs we obtainoptimal tradeoffs between the competitive ratio and the largestnumber of processors requested by any job.Our results demonstrate that on-line scheduling with dependenciesdiffers from scheduling without dependencies in several crucialaspects. First, it is essential to use virtualization, i.e., toschedule parallel jobs on fewer processors than requested. Second,the maximal number of processors requested by a job has significantinfluence on the performance. Third, the geometric structure of thenetwork topology is an even more important factor than in the absenceof dependencies.
