CHAINS OF STABILITY: BUILDING FINANCIAL AND CULTURAL COMMUNITY SUSTAINABILITY FOR LATINAS IN RICHMOND & CHESTERFIELD, VIRGINIA

As the Latinx population in the US continues to grow, new Latin-centric ethnic enclaves are developing in urban areas, including those in US southern states. While there has been some discourse on the role of Latin immigrants in the US labor market generally, there is limited literature addressing the specific experiences of Latinas as inhabitants of urban spaces and the factors impacting their economic sustainability. Latinas, on average, earn $0.54 to every$1.00 a white male earns. Their economic position, combined with their cultural traditions and practices, raises questions about how they achieve economic security in the US. This research uses Richmond and Chesterfield, Virginia as a case study to further explore the internal and external factors that positively and negatively impact Latinas\u27 economic well-being and how these translate into various forms of cultural capital. Based on the findings, I offer three key recommendations for planners to better support Latinas’ in Richmond and Chesterfield, Virginia

Using Latent Semantic Analysis to Evaluate the Coherence of Traumatic Event Narratives

While a growing evidence base suggests that expressive writing about a traumatic event may be an effective intervention which results in a variety of health benefits, there are still multiple competing theories that seek to explain expressive writing’s mechanism(s) of action. Two of the theories with stronger evidence bases are exposure theory and cognitive processing theory. The state of this field is complicated by methodological limitations; operationalizing and measuring the relative constructs of trauma narratives, such as coherence, traditionally requires time- and labor-intensive methods such as using a narrative coding scheme. This study used a computer-based methodology, latent semantic analysis (LSA), to quantify narrative coherence and analyze the relationship between narrative coherence and both short- and long-term outcomes of expressive writing. A subsample of unscreened undergraduates (N=113) who had been randomly assigned to the expressive writing group of a larger study wrote about the most traumatic event that had happened to them for three twenty-minute sessions; their narratives were analyzed using LSA. There were three main hypotheses, informed by cognitive processing theory: 1) That higher coherence in a given session would be associated with a more positive reported valence at the conclusion of that session, 2) that increasing narrative coherence across writing sessions would be associated with increasing reported valence at the conclusion of each session, and 3) that increasing narrative coherence over time would be associated with a decrease in post-traumatic stress symptoms. Overall, initial hypotheses were not supported, but higher coherence in the third writing session was associated with more negative valence at the conclusion of the session. Furthermore, relationships between pre- and post-session valence strengthened over time, and coherence, pre-session valence, and post-session valence all trended over time. These results suggest a collection of temporal effects, the implications of which are discussed in terms of future directions

The bldC developmental locus of Streptomyces coelicolor encodes a member of a family of small DNA-binding proteins related to the DNA-binding domains of the MerR family.

The bldC locus, required for formation of aerial hyphae in Streptomyces coelicolor, was localized by map-based cloning to the overlap between cosmids D17 and D25 of a minimal ordered library. Subcloning and sequencing showed that bldC encodes a member of a previously unrecognized family of small (58- to 78-residue) DNA-binding proteins, related to the DNA-binding domains of the MerR family of transcriptional activators. BldC family members are found in a wide range of gram-positive and gram-negative bacteria. Constructed {Delta}bldC mutants were defective in differentiation and antibiotic production. They failed to form an aerial mycelium on minimal medium and showed severe delays in aerial mycelium formation on rich medium. In addition, they failed to produce the polyketide antibiotic actinorhodin, and bldC was shown to be required for normal and sustained transcription of the pathway-specific activator gene actII-orf4. Although {Delta}bldC mutants produced the tripyrrole antibiotic undecylprodigiosin, transcripts of the pathway-specific activator gene (redD) were reduced to almost undetectable levels after 48 h in the bldC mutant, in contrast to the bldC+ parent strain in which redD transcription continued during aerial mycelium formation and sporulation. This suggests that bldC may be required for maintenance of redD transcription during differentiation. bldC is expressed from a single promoter. S1 nuclease protection assays and immunoblotting showed that bldC is constitutively expressed and that transcription of bldC does not depend on any of the other known bld genes. The bldC18 mutation that originally defined the locus causes a Y49C substitution that results in instability of the protein

The Effects of Organizational Philanthropic Movements and Related Public Relations Strategies

The following is a comprehensive public relations campaign created after extensive research on public relations efforts and corporate social responsibility. The study is mainly focused on establishing the relationship, if any, between a company’s philanthropic efforts and their profits. The study seeks to answer questions such as “Is the return on investment for philanthropic giving worth it?” and “How might this impact company morale?” With a focus on measuring the success of a philanthropic campaign created for Sereno Group Real Estate company, a small to midsize residential real estate company in the Silicon Valley, this study serves as a basis for understanding philanthropic efforts, where they stemmed from, and the type of impact they might have at the company level as well as even the global level. This text dives into the fundamentals of corporate social responsibility and terms that have evolved due to company’s lack of authenticity when creating these types of movements. Texts such as Yvon Chouinard’s Let My People Go Surfing and Guy Kawasaki’s Art of the Start in addition to personal interviews with industry level top executives are highly integrated into the study’s research, analysis, and conclusions. This study helps define the relationship, if any, between philanthropic public relations strategies and company success defined by public’s perception, company moral and culture, as well as company revenue and profits

War for the Wrong Reasons: Lessons from Law

In Ethics for Enemies, Frances Kamm argues that, under certain conditions, it is mor-ally permissible for a state to launch a war for opportunistic reasons. We consider how law might shed light on Kamm’s argument. Part I addresses the application of criminal and tort law to individual acts of violence analogous to the acts of war analyzed by Kamm. It primarily argues that these bodies of law rely on a framework for determining legal permissibility that runs counter to, and perhaps demonstrates weaknesses in, Kamm’s framework for assessing moral permissibility. Part II considers the law of war. It maintains that, although modern law permits certain opportunistic acts of war, the law does so on terms that cut against Kamm’s claim as to their moral permissibility

The melanin pigmentation: cellular and biomolecular mechanisms

Several factors are determinant for the color of human skin: the thickness of the stratum corneum, the speed of blood flow, the degree of oxygenation of hemoglobin but the main role is played by the presence of pigments such as carotenoids and, above all, melanin. The amount and the type of melanin is genetically determined, but they are strongly influenced by the other conditions such as hormonal and environmental: age, presence of metal ions, and inflammatory processes, and specifically exposure to sunlight. In vertebrates, melanocytes cells, responsible for the production of melanin, have the main function, but not exclusively, to protect the skin from the genotoxic stress produced by ultraviolet rays (UV); melanin absorbs the UV and neutralizers reactive oxygen species (ROS) they produce. Some studies clarified, at least in part, enzymatic and non enzymatic factors involved in the biosynthesis of melanin and the molecular mechanisms underlying the different responses of skin pigmentation to external stimuli, particularly to solar radiation. In this review we want to revise the cellular and biochemical aspects of skin pigmentation

Stellar Ages and Metallicities of Central and Satellite Galaxies: Implications for Galaxy Formation and Evolution

Using a large SDSS galaxy group catalogue, we study how the stellar ages and metallicities of central and satellite galaxies depend on stellar mass and halo mass. We find that satellites are older and metal-richer than centrals of the same stellar mass. In addition, the slopes of the age-stellar mass and metallicity-stellar mass relations are found to become shallower in denser environments. This is due to the fact that the average age and metallicity of low mass satellite galaxies increase with the mass of the halo in which they reside. A comparison with the semi-analytical model of Wang et al. (2008) shows that it succesfully reproduces the fact that satellites are older than centrals of the same stellar mass and that the age difference increases with the halo mass of the satellite. This is a consequence of strangulation, which leaves the stellar populations of satellites to evolve passively, while the prolonged star formation activity of centrals keeps their average ages younger. The resulting age offset is larger in more massive environments because their satellites were accreted earlier. The model fails, however, in reproducing the halo mass dependence of the metallicities of low mass satellites, yields metallicity-stellar mass and age-stellar mass relations that are too shallow, and predicts that satellite galaxies have the same metallicities as centrals of the same stellar mass, in disagreement with the data. We argue that these discrepancies are likely to indicate the need to (i) modify the recipes of both supernova feedback and AGN feedback, (ii) use a more realistic description of strangulation, and (iii) include a proper treatment of the tidal stripping, heating and destruction of satellite galaxies.
