Meaning making of a woman in her life development through the study abroad experience

Study Abroad continues to grow as part of the higher education experience. Women participate more often than men in Study Abroad, yet little research has addressed the narrative of a woman's unique voice in the process as an addition to knowledge. The objective of this study was to address the meaning a singular woman made from her participation in Study Abroad and how that meaning was expressed during her life journey.This qualitative study used narrative inquiry of a singular individual. Methods used for this research included individual interviews, observation, artifacts and photo elicitation. The member's own photos were used for the photo elicitation and proved a strong resource. Data collection from the methods and applied coding process emerged five themes: People are good: this data described an intense need for the participant to acknowledge the goodness of all people. The need to tell: this collected data that demonstrated the participant's need to share her acquired epiphany to enlighten others. Independence: this gathering evidenced a new degree of freedom in solo travel and general self-confidence. Places: location and the need for familiar landscape data grounded the participant. Finally, Race: indicated data that described an attention to people because of their cultural differences. The final analysis includes poetry pulled from Labov's coding process, as well as an acrylic painting to visually represent the findings.The significance of this study was the reflection she shared as a woman because it begins to fill in gaps from the historical narratives that document history through voice. The study was not intended to generalize to others but rather valued as a unique solo note. There were some possible implications from this study. Learning may grow from how a person views self. Therefore, understanding what is important to the learner may allow for the development of higher education initiatives that enhance participant satisfaction and increase positive results. The most profound meaning pulled from the narrative for this participant was associated with how she approached the world, acceptance of people and finally the courage to believe in herself

Flavonoid-Rich Mixed Berries Maintain and Improve Cognitive Function Over a 6h Period in Young Healthy Adults

Research with young adults has previously indicated flavonoid-rich berry interventions facilitate improved executive function (EF) and positive affect 20 min–2 h post-dosing. There has been little consideration of the impact of a berry intervention over a working day and interventions have also tended to consider only a single berry type. This study investigated the temporal profile of EF and mood changes over a 6 h period following a mixed-berry intervention. We hypothesized berry-related benefits would be most evident when participants were cognitively compromised on demanding elements of the task or during periods of fatigue. The study employed a single-blind, randomized, placebo controlled, between-subjects design. Forty participants aged 20–30 years consumed a 400 mL smoothie containing equal blueberry, strawberry, raspberry, and blackberry (n = 20) or matched placebo (n = 20). Mood was assessed using the Positive and Negative Affect Schedule; EF was tested using the Modified Attention Network (MANT) and Task Switching (TST) Tasks. Testing commenced at baseline then 2, 4 and 6 h post-dosing. As expected, following placebo intervention, performance decreased across the day as participants became cognitively fatigued. However, following berry intervention, participants maintained accuracy on both cognitive tasks up to and including 6 h, and demonstrated quicker response times on the MANT at 2 and 4 h, and TST at 6 h. This study demonstrates the efficacy of flavonoid rich berries in maintaining or improving cognitive performance across the 6 h day

Landscape, Memory, and the Shifting Regional Geographies of Northwest Bosnia-Herzegovina

Writing and arguing with older discourses that have informed the subdiscipline of regional geography and setting them against new ways of conceiving of the region, this article considers the northwest of Bosnia-Herzegovina as a site that calls for a newly animated form of regional study. Of particular concern here is the role that memory and commemorative practices play in such a spatial schema. The monumental landscapes of the Tito regime and its collective commemoration of World War II sit alongside and are troubled by the more recent traumas and spaces of unmarked death associated with the ethnic war in Bosnia during the early 1990s. Read together, northwest Bosnia-Herzegovina functions as a vivid exemplar for understanding traumatic historical mourning as a phenomenological process that is inseparable from the wider geopolitical landscape

Phagocytosis by an HIV antibody is associated with reduced viremia irrespective of enhanced complement lysis

Increasingly, antibodies are being used to treat and prevent viral infections. In the context of HIV, efficacy is primarily attributed to dose-dependent neutralization potency and to a lesser extent Fc-mediated effector functions. It remains unclear whether augmenting effector functions of broadly neutralizing antibodies (bNAbs) may improve their clinical potential. Here, we use bNAb 10E8v4 targeting the membrane external proximal region (MPER) to examine the role of antibody-mediated effector and complement (C’) activity when administered prophylactically against SHIV challenge in rhesus macaques. With sub-protective dosing, we find a 78–88% reduction in post-acute viremia that is associated with 10E8v4-mediated phagocytosis acting at the time of challenge. Neither plasma nor tissue viremic outcomes in vivo is improved with an Fc-modified variant of 10E8v4 enhanced for C’ functions as determined in vitro. These results suggest that effector functions inherent to unmodified 10E8v4 contribute to efficacy against SHIVSF162P3 in the absence of plasma neutralizing titers, while C’ functions are dispensable in this setting, informing design of bNAb modifications for improving protective efficacy

Getting your DUCs in a row - standardising the representation of Digital Use Conditions

Improving patient care and advancing scientific discovery requires responsible sharing of research data, healthcare records, biosamples, and biomedical resources that must also respect applicable use conditions. Defining a standard to structure and manage these use conditions is a complex and challenging task. This is exemplified by a near unlimited range of asset types, a high variability of applicable conditions, and differing applications at the individual or collective level. Furthermore, the specifics and granularity required are likely to vary depending on the ultimate contexts of use. All these factors confound alignment of institutional missions, funding objectives, regulatory and technical requirements to facilitate effective sharing. The presented work highlights the complexity and diversity of the problem, reviews the current state of the art, and emphasises the need for a flexible and adaptable approach. We propose Digital Use Conditions (DUC) as a framework that addresses these needs by leveraging existing standards, striking a balance between expressiveness versus ambiguity, and considering the breadth of applicable information with their context of use

CD8+ T Cells from SIV Elite Controller Macaques Recognize Mamu-B*08-Bound Epitopes and Select for Widespread Viral Variation

Background. It is generally accepted that CD8(+) T cell responses play an important role in control of immunodeficiency virus replication. the association of HLA-B27 and -B57 with control of viremia supports this conclusion. However, specific correlates of viral control in individuals expressing these alleles have been difficult to define. We recently reported that transient in vivo CD8(+) cell depletion in simian immunodeficiency virus (SIV)-infected elite controller (EC) macaques resulted in a brief period of viral recrudescence. SIV replication was rapidly controlled with the reappearance of CD8(+) cells, implicating that these cells actively suppress viral replication in ECs. Methods and Findings. Here we show that three ECs in that study made at least seven robust CD8(+) T cell responses directed against novel epitopes in Vif, Rev, and Nef restricted by the MHC class I molecule Mamu-B*08. Two of these Mamu-B*08-positive animals subsequently lost control of SIV replication. Their breakthrough virus harbored substitutions in multiple Mamu-B*08-restricted epitopes. Indeed, we found evidence for selection pressure mediated by Mamu-B*08-restricted CD8(+) T cells in all of the newly identified epitopes in a cohort of chronically infected macaques. Conclusions. Together, our data suggest that Mamu-B*08-restricted CD8(+) T cell responses effectively control replication of pathogenic SIV(mac)239. All seven regions encoding Mamu-B*08-restricted CD8(+) T cell epitopes also exhibit amino acid replacements typically seen only in the presence of Mamu-B*08, suggesting that the variation we observe is indeed selected by CD8(+) T cell responses. SIVmac239 infection of Indian rhesus macaques expressing Mamu-B*08 may therefore provide an animal model for understanding CD8(+) T cell-mediated control of HIV replication in humans.National Institutes of Health (NIH)National Center for Research Resources (NCRR)Japan Health Sciences FoundationKent State University Research CouncilOhio Board of Regents Research ChallengeResearch Facilities ImprovementUniv Wisconsin, WNPRC, Madison, WI 53706 USAUniversidade Federal de São Paulo, Div Infect Dis, São Paulo, BrazilUniv Wisconsin, Dept Pathol & Lab Med, Madison, WI USALa Jolla Inst Allergy & Immunol, Div Vaccine Discovery, La Jolla, CA USAUniv Oxford, John Radcliffe Hosp, Weatherall Inst Mol Med, Oxford OX3 9DU, EnglandKent State Univ, Dept Biol Sci, Kent, OH 44242 USAUniv S Carolina, Dept Biol Sci, Columbia, SC 29208 USAUniversidade Federal de São Paulo, Div Infect Dis, São Paulo, BrazilNational Institutes of Health (NIH): HHSN266200400088CNational Institutes of Health (NIH): R01 AI049120National Institutes of Health (NIH): R01 AI052056National Institutes of Health (NIH): R24 RR015371National Institutes of Health (NIH): R24 RR016038National Institutes of Health (NIH): R21 AI068586National Center for Research Resources (NCRR): P51 RR000167Japan Health Sciences Foundation: GM43940Research Facilities Improvement: RR15459-01Research Facilities Improvement: RR020141-01Web of Scienc

Getting a Head Start: Diet, Sub-Adult Growth, and Associative Learning in a Seed-Eating Passerine

Developmental stress, and individual variation in response to it, can have important fitness consequences. Here we investigated the consequences of variable dietary protein on the duration of growth and associative learning abilities of zebra finches, Taeniopygia guttata, which are obligate graminivores. The high-protein conditions that zebra finches would experience in nature when half-ripe seed is available were mimicked by the use of egg protein to supplement mature seed, which is low in protein content. Growth rates and relative body proportions of males reared either on a low-protein diet (mature seed only) or a high-protein diet (seed plus egg) were determined from body size traits (mass, head width, and tarsus) measured at three developmental stages. Birds reared on the high-protein diet were larger in all size traits at all ages, but growth rates of size traits showed no treatment effects. Relative head size of birds reared on the two diets differed from age day 95 onward, with high-diet birds having larger heads in proportion to both tarsus length and body mass. High-diet birds mastered an associative learning task in fewer bouts than those reared on the low-protein diet. In both diet treatments, amount of sub-adult head growth varied directly, and sub-adult mass change varied inversely, with performance on the learning task. Results indicate that small differences in head growth during the sub-adult period can be associated with substantial differences in adult cognitive performance. Contrary to a previous report, we found no evidence for growth compensation among birds on the low-protein diet. These results have implications for the study of vertebrate cognition, developmental stress, and growth compensation

Scientists' Warning to Humanity on Threats to Indigenous and Local Knowledge Systems

The knowledge systems and practices of Indigenous Peoples and local communities play critical roles in safeguarding the biological and cultural diversity of our planet. Globalization, government policies, capitalism, colonialism, and other rapid social-ecological changes threaten the relationships between Indigenous Peoples and local communities and their environments, thereby challenging the continuity and dynamism of Indigenous and Local Knowledge (ILK). In this article, we contribute to the “World Scientists' Warning to Humanity,” issued by the Alliance of World Scientists, by exploring opportunities for sustaining ILK systems on behalf of the future stewardship of our planet. Our warning raises the alarm about the pervasive and ubiquitous erosion of knowledge and practice and the social and ecological consequences of this erosion. While ILK systems can be adaptable and resilient, the foundations of these knowledge systems are compromised by ongoing suppression, misrepresentation, appropriation, assimilation, disconnection, and destruction of biocultural heritage. Three case studies illustrate these processes and how protecting ILK is central to biocultural conservation. We conclude with 15 recommendations that call for the recognition and support of Indigenous Peoples and local communities and their knowledge systems. Enacting these recommendations will entail a transformative and sustained shift in how ILK systems, their knowledge holders, and their multiple expressions in lands and waters are recognized, affirmed, and valued. We appeal for urgent action to support the efforts of Indigenous Peoples and local communities around the world to maintain their knowledge systems, languages, stewardship rights, ties to lands and waters, and the biocultural integrity of their territories—on which we all depend.Peer reviewe
