Reporting the movement in black and white: the Emmett Till lynching and the Montgomery bus boycott

This dissertation examines media coverage of two events in the Civil Rights Movement-the lynching of Emmett Till in 1955 and the Montgomery bus boycott in 1955-56. The study focuses on three publications aimed primarily at white audiences (Life, Look and the New York Times) and two aimed primarily at black audiences (the Birmingham World and Jet). The dissertation seeks to answer several questions. How did mainstream news organizations cover black Americans in the decades prior to the 1950s? In reporting on the Till murder case and the Montgomery bus boycott, did coverage by mainstream news organizations change? If so, in what ways? And, most important, which news organizations did the best job covering the Till murder case and the Montgomery bus boycott? The researcher defined best as those publications that quoted a diversity of sources, provided historical context and identified the central problem while following accepted journalistic routines such as attribution and balance. The researcher examined every story and photograph published by the five news organizations about the Till lynching and the Montgomery bus boycott. The researcher used textual analysis as the primary methodology. The study also incorporated two mass communication theories-framing and cultural studies. The dissertation found that the black-oriented publications produced the most accomplished journalistic coverage by providing a greater range of sources, broader context, more depth and a clear statement of the central problem. The study showed that during the first half of the twentieth century, mainstream news organizations largely ignored blacks or presented them as criminals. But this changed during the Till murder case and the bus boycott. The dissertation found that in reporting on these events, Life, Look and the New York Times adopted new frames-first presenting blacks as the innocent victims of deadly racial hatred and later as nonviolent protestors. These findings challenge the widely held opinion that the New York Times provides the best journalistic source of information on key historical events. This study also challenges the widespread view that the black press is a fighting press that uses its news columns to advance a political agenda

Ethics-Relevant Values as Antecedents of Personality Change: Longitudinal Findings from the Life and Time Study

What leads personality to develop in adulthood? Values, guiding principles that apply across contexts, may capture motivation for growth and change. An essentialist trait perspective posits that personality changes only as a result of organic factors. But evidence suggests that psychosocial factors also influence personality change, especially during young adulthood. In the Life and Time study of sources of personality change in adulthood, we specifically explore ethically-relevant value priorities, those related to the relative prioritization of narrow self-interest over the concerns of a larger community. According to Rollo May (1967), “mature values”, including aspects of both self-transcendence and self-determination, should serve to diminish or prevent neurotic anxiety. This is consistent with research on materialism, which is associated with lower well-being. An index based on May’s proposal and several related constructs (materialism, unmitigated self-interest, collectivism and individualism) are tested longitudinally as possible antecedents of Big Five/Six personality trait change using bivariate LCMSR models in a national community sample (N = 864 at Time 1). Contrary to an essentialist trait perspective, these value priorities more often preceded change in personality traits than vice-versa. Somewhat consistent with May’s theory, higher “mature” values preceded higher openness (statistically significant at the p < .005 level). Higher vertical individualism significantly preceded lower compassion, intellect and openness. At the suggestive (p < .05) level, higher unmitigated self-interest preceded lower conscientiousness, higher vertical individualism preceded higher volatility, higher mature values preceded higher honesty/propriety and politeness, higher horizontal collectivism preceded higher orderliness, agreeableness, and assertiveness and lower intellect, and higher horizontal individualism preceded lower withdrawal. In two of three cases, suggestive personality-as-antecedent-of-values-change effects were reciprocal with the values-effects: higher conscientiousness scores reciprocally preceded lower unmitigated self-interest, and higher volatility higher vertical individualism. No significant or suggestive “stand-alone”, non-reciprocal personality on values effects were found

Effective intra-S checkpoint responses to UVC in primary human melanocytes and melanoma cell lines

The objective of this study was to assess potential functional attenuation or inactivation of the intra-S checkpoint during melanoma development. Proliferating cultures of skin melanocytes, fibroblasts and melanoma cell lines were exposed to increasing fluences of UVC and intra-S checkpoint responses were quantified. Melanocytes displayed stereotypic intra-S checkpoint responses to UVC qualitatively and quantitatively equivalent to those previously demonstrated in skin fibroblasts. In comparison to fibroblasts, primary melanocytes displayed reduced UVC-induced inhibition of DNA strand growth and enhanced degradation of p21Waf1 after UVC, suggestive of enhanced bypass of UVC-induced DNA photoproducts. All nine melanoma cell lines examined, including those with activating mutations in BRAF or and NRAS oncogenes, also displayed proficiency in activation of the intra-S checkpoint in response to UVC irradiation. The results indicate that bypass of oncogene-induced senescence during melanoma development was not associated with inactivation of the intra-S checkpoint response to UVC-induced DNA replication stress

Developmental Changes in Dynamic Functional Connectivity From Childhood Into Adolescence

The longitudinal study of typical neurodevelopment is key for understanding deviations due to specific factors, such as psychopathology. However, research utilizing repeated measurements remains scarce. Resting-state functional magnetic resonance imaging (MRI) studies have traditionally examined connectivity as ‘static’ during the measurement period. In contrast, dynamic approaches offer a more comprehensive representation of functional connectivity by allowing for different connectivity configurations (time varying connectivity) throughout the scanning session. Our objective was to characterize the longitudinal developmental changes in dynamic functional connectivity in a population-based pediatric sample. Resting-state MRI data were acquired at the ages of 10 (range 8-to-12, n = 3,327) and 14 (range 13-to-15, n = 2,404) years old using a single, study-dedicated 3 Tesla scanner. A fully-automated spatially constrained group-independent component analysis (ICA) was applied to decompose multi-subject resting-state data into functionally homogeneous regions. Dynamic functional network connectivity (FNC) between all ICA time courses were computed using a tapered sliding window approach. We used a k-means algorithm to cluster the resulting dynamic FNC windows from each scan session into five dynamic states. We examined age and sex associations using linear mixed-effects models. First, independent from the dynamic states, we found a general increase in the temporal variability of the connections between intrinsic connectivity networks with increasing age. Second, when examining the clusters of dynamic FNC windows, we observed that the time spent in less modularized states, with low intra- and inter-network connectivity, decreased with age. Third, the number of transitions between states also decreased with age. Finally, compared to boys, girls showed a more mature pattern of dynamic brain connectivity, indicated by more time spent in a highly modularized state, less time spent in specific states that are frequently observed at a younger age, and a lower number of transitions between states. This longitudinal population-based study demonstrates age-related maturation in dynamic intrinsic neural activity from childhood into adolescence and offers a meaningful baseline for comparison with deviations from typical development. Given that several behavioral and cognitive processes also show marked changes through childhood and adolescence, dynamic functional connectivity should also be explored as a potential neurobiological determinant of such changes

A comment on Ellwood-Lowe et al. (2020/2021): Presentation and discussion of results should take the lead from the preregistration

Preregistration establishes transparent and verifiable links between hypotheses, statistical tests, and error-control of decisions. In this comment, I critique both the preregistration of, and the presentation of preregistered results from two studies investigating scarcity as a potential cause of the word gap. The primary goal is to illustrate how and why preregistration should guide the way results are framed, and how this might influence conclusions drawn

Adolescent Social Motives: Measurement and Implications

The study of decision making during adolescence has received considerable attention throughout the history of developmental psychology, justifiably, given the marked increases in morbidity and mortality that belie otherwise robust health. Although the dominant theories invoked to help explain decision-making during adolescence acknowledge the existence of motivations that are thought to be central to this developmental period, there is little work that investigates the effects of these motives, per se. In particular, motivations toward developing sexual and romantic relationships, as well as toward navigating peer status hierarchies have both been acknowledged as especially relevant for this period of development. Almost all research in this area focuses on self-report, and is heavily weighted toward the domain of status and popularity. A major gap in this literature is an understanding of how adolescent-relevant motivations affect basic behavioral processes, and of the consequences of individual differences in motivations. The current investigation uses reinforcement learning to examine the effects of social motives on stimulus salience. This may allow both indirect, behavioral measurement of motivations, and is itself a potential mechanism by which motivations affect behavior via experience of the environment, and learning. Adolescent (N = 104) and college student (N = 230) participants learned four social-motive-relevant, and two baseline face-word associations. Learning was characterized using both proportion of optimal responses in the last half of the learning task, and a Rescorla-Wagner-like computational model. Results showed greater learning, and higher learning rates, in the social-motive conditions. In order to explore the validity of behavior on the task as a measure of particular motivations, individual learning differences between social and baseline conditions were compared with developmental indices, self-report traits, and self-report health-relevant behaviors. Older participants were better at the learning task, but social-motive learning enhancement was constant across development. Measures of social-motive effects on learning did not correlate with self-reported traits or health-related behaviors. The effects of motive-relevant words on learning may be due to factors unrelated to motivation, but research design may also be problematic. Self-report trait instruments performed well, but a more comprehensive taxonomy of motivational constructs and measures would be beneficial
