Race and Colorism in the Latinx Community
No full textAfro-Latinx people in the United States have long been rendered invisible due to lack of representation in media produced in both Latin American and mainstream American culture. As they come into visibility through the use of social media and popular culture spaces, specifically Hip-Hop, they face particular challenges and negotiations surrounding their claims and performances of both Blackness and Latinidad. This is largely due to the structural binary that posits Black and White as the two poles of race in the United States, notions of racial/ethnic authenticity, and how colorism operates within the Latinx and Black communities which influence how Afro-Latinx people may identify. By using Afro-Latinx people, who are associated with Hip-Hop Culture as a case study, and Twitter as a virtual field site, I seek to understand the distinct negotiations that Afro-Latinx people face surrounding their blackness in the United States
Dyadic synchrony among young Latina mothers and their toddlers: The role of maternal and child behavior
No full textSynchronous interactions are an important indicator of parent-child relationship quality with positive implications for child development. Latina adolescent mothers face several demographic challenges that place them at risk for less synchronous interactions. To identify factors that may facilitate more optimal parent-child relationships in this population, our study examined maternal sensitivity and children’s behavioral styles as joint predictors of dyadic synchrony among young Latina mothers and their toddlers. Mother-toddler dyads (N=170) were observed interacting across different tasks, and toddlers’ behavior was observed during the administration of a developmental test. Results of multivariate regressions revealed additive effects of maternal sensitivity and child behavioral styles (i.e., dysregulation and positive attentional control). Maternal sensitivity related to higher dyadic synchrony for the entire sample. Positive attentional control was related to higher dyadic synchrony for mother-daughter dyads only. Although no gender differences in dyadic synchrony or the behavior style variables emerged, the relative contribution of maternal and child factors differed by child gender, suggesting that mothers may have responded differently to similar behavior and affect displayed by boys and girls. The f indings provide insights regarding factors that contribute to dyadic synchrony in this understudied population and emphasize the need to consider child gender when studying parent-child interactions in young Latina families
Heterocyclic β-keto sulfide derivatives of carvacrol: Synthesis and copper (II) ion reducing capacity
No full textSixteen β-keto sulfide derivatives of carvacrol (4–19) incorporating phenyl or N, O and S heterocyclic moieties were synthesized in three steps. The relationships between heterocyclic structure and cupric, Cu(II), ion reducing antioxidant capacity (CUPRAC) were examined. Nine of the compounds (8–9 and 13–19) showed better CUPRAC activity than trolox at neutral pH, with trolox equivalent antioxidant capacity (TEAC) coefficients ranging between 1.20 and 1.75. Two derivatives (11–12) showed comparable reducing capacity to trolox, with TEAC values of 0.95 for 11 and 1.02 for 12. Compounds 8–9 and 11–19 were more effective at reducing the Cu (II) ion than ascorbic acid and the parent compound, carvacrol. The most effective antioxidants were those containing an oxadiazole, thiadiazole or triazole moiety. In particular, the methyl thiadiazole derivative (15) had the highest Cu(II) ion reducing capacity, with a TEAC coefficient of 1.73
Effects of Intrauterine Global Restriction on Reward Processing of Offspring
No full textObesity in recent years has become the leading cause of death and is associated with over 60 high risk diseases. Evidence indicates that the in utero environment significantly impacts fetal development via the process of gestational programming. In particular, maternal nutrition appears to play a significant part in the development of offspring addictive tendencies. Tyrosine hydroxylase (TH), the rate limiting enzyme for the production of the reward neurotransmitter, dopamine, acts in the ventral tegmental area (VTA) to reinforce rewarding behaviors. In this study, we used global caloric maternal restriction during gestation to produce intrauterine growth restricted (IGUR) offspring in rats, to understand how expression of TH expression is affected in the reward pathway of IUGR offspring. We hypothesize that alterations in VTA TH expression will explain observed increases in binge-like consumption of rewarding substances, such as sucrose observed in IUGR offspring
Social Media, Personality, and Alcohol Use
No full textShort abstract: Videos of college students drinking are readily available on social media. Is watching such videos related to attitudes toward college drinking culture? Our 125 college student participants indicated how often they watch such videos on different social media platforms and completed a measure of the role of alcohol in college life. The predicted correlation was not found, although students who drink did watch more frequently. Fear of missing out (FOMO) was positively correlated with attitude. For female participants Fear of Missing out was also positively correlated with consumption of alcohol
Growth rates of M. centralius, M. silvanus, and M. ruber in methanol and carbon-depleted media
No full textMetathermus centralius, unlike the closely related Metathermus silvanus and Meiothermus ruber, contains a genetic pathway that potentially grants M. centralius the ability to digest methanol on minimal media. M. centralius, M. silvanus, and M. ruber were cultivated in media lacking several carbon sources and monitored for growth. Depriving them of nutrients revealed strong growth of M. centralius in standard media, with positive growth in single, double, and triple carbon-lacking media. M. silvanus and M. ruber seemed to lack the ability to grow in minimal media. Addition of 600 mM and 900 mM methanol to standard media reduces growth rates of all three but, under current conditions, does not yet select for M. centralius over the control strains. Future analyses of the bacteria in carbon-depleted media with supplemental methanol are predicted to reveal stronger M. centralius growth when compared to M. silvanus, and M. ruber
Photocatalytic Degradation Rates of Warfarin placed in Sodium Hydroxide and a UV Reactor
No full textPhotocatalytic degradation of pharmaceuticals is being used to determine if a practical method of disposal is a useful alternative to expensive incineration. Disposal of unused drugs is usually done in the household garbage, which can lead negative impacts on the environment or to people due to misuse and abuse. Photocatalytic degradation of pharmaceuticals is a promising alternative for proper disposal. Photocatalytic degradation of (RS)-4-hydroxy-3-(3-oxo-1-phenylbutyl)-2H-chromen-2-one (warfarin) was evaluated. Warfarin was initially left alone to see how to would degrade over time and then was also placed in sodium hydroxide (NaOH). All degradation rates were compared with a control with no UV exposure. High Performance Liquid Chromatography (HPLC) was used to analyze the drug remaining in the solutions over time. Initial results indicate that degradation with UV light and no acid show that there is not much decay over time, the results of the degradation with NaOH and the UV light show that warfarin is degrading over time in the NaOH solution and with the UV light
Effects of Arctic Sea Ice Loss on Frequency of Cold Weather in Mid-Latitudes
No full textAnthropogenic climate change has caused Arctic sea ice to melt at a rapid rate, but up until recently it has not been considered that this melting would affect synoptic weather patterns, only long-term climate factors. This research attempts to establish a connection between melting Arctic sea ice, changes in the jet stream and tropospheric polar vortex, and the frequency of extreme cold weather events in the mid-latitudes. Cold events during the months of December-February are analyzed over the past decade and compared with a 30-year climatology using NCEP-DOE AMIP-II Reanalysis data, and correlated with measures of Arctic sea ice concentration. Observations are analyzed to show the relationship between loss of Arctic sea ice, a weakening jet stream, and changes in the frequency of cold days occurring in the mid-latitudes
The Simurgh Initiative: Communicating the Preservation and Destruction of the Middle East and North Africa’s Cultural Heritage
No full textMisunderstanding and the complexity of the issues underlie contemporary conversations regarding cultural heritage. Representing the longevity and salience of the region’s cultural heritage, inspiration for action is found in the Simurgh—a mythical bird of the Middle East, often equated with the phoenix. The Simurgh Initiative culminates as a digital humanities project and website, communicating contemporary events surrounding the preservation and destruction of the Middle East and North Africa’s cultural heritage. The website caters to a wide variety of backgrounds with introductions to preservation and destruction, topical essays (including accessibility to cultural sites during times of conflict, smuggled and looted objects, and Western military involvement), and a resource database for scholars. As a multimedia tool, the website aims to streamline research on the cultural heritage field. Focusing on Egypt, Syria, and Iraq, the initiative is the product of a ten-person, cross-departmental team of Susquehanna University students and professor David Heayn
The Effects of Societal and Economic Factors on Youth Crime in the United States
No full textYouth crime is a serious problem for society, as this population – the youth or those under the age of 18 years old – is responsible for dictating and beautifying the future. The primary aim of this report is to distinguish and explore the multiple variables or factors that contribute to youth crime in the United States. Although youth crime in the United States has fallen in past years, further steps and actions need to be taken in an attempt to ensure safety and productivity for this population and for society as a whole (The Office of Juvenile Justice and Delinquency Prevention, 2017)
