Identification, discrimination, and selective adaptation of simultaneous musical intervals

Four experiments investigated perception of major and minor thirds whose component tones were sounded simultaneously. Effects akin to categorical perception of speech sounds were found. In the first experiment, musicians demonstrated relatively sharp category boundaries in identification and peaks near the boundary in discrimination tasks of an interval continuum where the bottom note was always an F and the top note varied from A to A flat in seven equal logarithmic steps. Nonmusicians showed these effects only to a small extent. The musicians showed higher than predicted discrimination performance overall, and reaction time increases at category boundaries. In the second experiment, musicians failed to consistently identify or discriminate thirds which varied in absolute pitch, but retained the proper interval ratio. In the last two experiments, using selective adaptation, consistent shifts were found in both identification and discrimination, similar to those found in speech experiments. Manipulations of adapting and test showed that the mechanism underlying the effect appears to be centrally mediated and confined to a frequency-specific level. A multistage model of interval perception, where the first stages deal only with specific pitches may account for the results.

Duration discrimination in a series of rhythmic events

Duration discrimination of the last of a series of four clicks was investigated. Examination of psychophysical functions from eight subjects revealed evidence for a Weber’s law model relating discrimination to base interclick interval. Also, the point of subjective equality was seen to change reliably as a function of base rate.

America's Shifting Color Line? Reexamining Determinants of Latino Racial Self-Identification

Objectives. Latinos are the nation's largest minority group and will double in size by 2050. Their size coupled with the fact that Latinos do not constitute a separate race raises questions about Latinos' incorporation into the U. S. racial hierarchy. This article explores patterns of Latino racial identity formation, examining the determinants of racial identity. Methods. Using the 2006 Latino National Survey, I estimate multinomial logit and ordered probit models of identification choices. Results. Latino racial identity is strongly associated with several factors, including socioeconomic status, measures of perceived discrimination and commonality, and measures of acculturation/assimilation. Most Latinos have a broader, more complex understanding of race. Furthermore, some Latinos do believe that they occupy a unique position in the racial hierarchy. Conclusions. The results suggest that the color line W. E. DuBois argued has long divided our nation may eventually shift.

Should Countries Engage in a Race to the Bottom? The Effect of Social Spending on FDI

This paper examines the effect of social spending in developing countries on foreign direct investment (FDI). Existing studies on the race to the bottom in social services attempt to discern the extent to which FDI affects social expenditure. However, it remains an open question whether FDI is actually attracted to lower spending levels. We find no indication that FDI is repelled by social spending; indeed there is strong evidence that investment is associated with greater programmatic emphases on health and education. These findings have important implications for leaders seeking to attract investment and for those attempting to expand social programs.

MR imaging of parotid tumors: typical lesion characteristics in MR imaging improve discrimination between benign and malignant disease

The surgical approach to parotid tumors is different for benign and malignant neoplasms, but the clinical symptoms do not correlate well with histology. Difficulties in tumor classification also arise in imaging modalities, in which sonography has the lowest and MR imaging, the highest accuracy. The purpose of this study was to review our experience using conventional MR imaging of the neck in the evaluation of parotid tumors and to evaluate which MR imaging findings are best able to predict malignant histology.

Chinese Whiteness: The Discourse Of Race In Modern And Contemporary Chinese Culture

This thesis chronicles the development of western forms of race and racism in China. It then studies contemporary China using theories derived from whiteness studies in order to explain the unique position that whites (Caucasians) have in China today. In Chapter I, I break down the definition of race and introduce a foundation for a whiteness studies approach to research. In Chapter II, I analyze how Chinese classified themselves and other humans prior to the western system of race. In Chapter III, I chronicle the introduction of western forms of race and racism to China, and the appropriation of these concepts to suit Chinese goals. In Chapter IV, I approach cultural phenomenon in contemporary China by situating them in their historical traditions as well as by approaching them as displaying an internalized racism and white privilege. Finally in the Conclusion, I postulate on what China¿s contemporary racial system means for China.

Restructuring Justice: Moving Towards Gender-Responsive Programming and Alternatives to Incarceration for Non-Violent Female Offenders

The United States¿ Federal and State laws differentiate between acceptable (or, legal) and unacceptable (illegal) behavior by prescribing restrictive punishment to citizens and/or groups that violate these established rules. These regulations are written to treat every person equally and to fairly serve justice; furthermore, the sanctions placed on offenders seek to reform illegal behavior through limitations on freedoms and rehabilitative programs. Despite the effort to treat all offenders fairly regardless of social identity categories (e.g., sex, race, ethnicity, socioeconomic status, age, ability, and gender and sexual orientation) and to humanely eliminate illegal behavior, the American penal system perpetuates de facto discrimination against a multitude of peoples. Furthermore, soaring recidivism rates caused by unsuccessful re-entry of incarcerated offenders puts economic stress on Federal and State budgets. For these reasons, offenders, policy-makers, and law-abiding citizens should all have a vested interest in reforming the prison system. This thesis focuses on the failure of the United States corrections system to adequately address the gender-specific needs of non-violent female offenders. Several factors contribute to the gender-specific discrimination that women experience in the criminal justice system: 1) Trends in female criminality that skew women¿s crime towards drug-related crimes, prostitution, and property offenses; 2) Mandatory minimum sentences for drug crimes that are disproportionate to the crime committed; 3) So-called ¿gender-neutral¿ educational, vocational, substance abuse, and mental health programming that intends to equally rehabilitate men and women, but in fact favors men; and 4) The isolating nature of prison structures that inhibits smooth re-entry into society. I argue that a shift in the placement and treatment of non-violent female offenders is necessary for effective rehabilitation and for reducing recidivism rates. The first component of this shift is the design and implementation of gender- responsive treatment (GRT) rather than gender-neutral approaches in rehabilitative programming. The second shift is the utilization of alternatives to incarceration, which provide both more humane treatment of offenders and smoother reintegration to society. Drawing on recent scholarship, information from prison advocacy organizations, and research with men in an alternative program, I provide a critical analysis of current policies and alternative programs, and suggest several proposals for future gender- responsive programs in prisons and in place of incarceration. I argue that the expansion of gender-responsive programming and alternatives to incarceration respond to the marginalization of female offenders, address concerns about the financial sustainability of the United States criminal justice system, and tackle high recidivism rates.

Child Aggression in a Post-Communist Country: Race and Gender Aspects in a Cross-Cultural Comparison

Gypsies represent approximately 2.5% of the Czech population, but are considerably over-represented among the unemployed, prisoners, schooldropouts, neglected children, etc. Together with racist attitudes on the part of the majority, this causes strong inter-ethnic tension and obviouseconomic, moral and political problems. This research studied the way in which this situation is reflected in peer relations between Gypsy andmajority children in schools. Six samples of children (totalling 2974 children aged 7-15, of whom 15% were Gypsies) were studied through peernomination, teacher assessment and self-reporting. Gypsy/non-Gypsy and gender dichotomies were correlated with measures of aggression,victimisation and acceptance/rejection. The results showed that Gypsy children, both boys and girls, were more likely to nominate their Gypsy peers as aggressors than they nominatemajority children, implying that they tend to direct their rejection toward their own kind. The number of Gypsy children in a class was also animportant factor with Gypsies being more likely to be accepted and less likely to appear aggressive when they were only one or two in a class, thanin a class where there was a greater number of Gypsy pupils. When whole classes were taken as the unit of analysis, Gypsy children were seen asmore likely to behave aggressively in class by their Gypsy and non-Gypsy counterparts as well as by their teachers. At the same time they aremuch less likely to become victims of aggression than are non-Gypsy children, both boys and girls. Mr. Rican also found that the acceptance/rejection patterns of Gypsy children betray their unsatisfactory socialisation. Among their peers, Gypsyor non-Gypsy, they tend to prefer aggressors or children who teachers describe as showing little discipline or effort to succeed at school. Partialcorrelation to assess the influence of seniority on aggressiveness provided a warning that the recent lengthening of compulsory school attendance islikely to bring an increase in aggressiveness. He believes that Gypsy ethnic identity has lost many of its important positive aspects, making itsnegative aspects more prominent and more dangerous. He does however find some possible ways for teachers to reinforce the positive aspects ofGypsy children's identities in order to support their socialisation at schools.
