African American Students\u27 Perceptions of Influential Factors for Attendance in Doctoral Psychology
This study explores African American undergraduate studentsâ perceptions of factors influencing their decision to attend doctoral programs in psychology. There is a scarcity of literature examining perceptions held by specific minority groups in regard to influential factors used to make a significant step toward their career development. Eight undergraduate students interested in pursuing a doctoral degree in psychology were interviewed. A semi-structured interview and two paper-pencil measures were used. Interviews were analyzed utilizing the consensual qualitative research (CQR) method. The following themes emerged: reasons for pursuing a doctoral degree, navigating the application process, factors influencing interest in psychology, perception of a programâs commitment to diversity, importance of ethnic minority representation in a program, financial concerns, family view of psychology, most important factor for attendance, and prior school experiences outside of psychology. The study found that issues related to African American representation and research, as well as the presence of financial aid, are highly relevant in studentsâ evaluation of which doctoral programs they prefer to attend. This information will pave the way for further studies focusing on how to increase the number of African American students in doctoral programs around the country
Ophthalmic Biomarker Detection Using Ensembled Vision Transformers -- Winning Solution to IEEE SPS VIP Cup 2023
This report outlines our approach in the IEEE SPS VIP Cup 2023: Ophthalmic
Biomarker Detection competition. Our primary objective in this competition was
to identify biomarkers from Optical Coherence Tomography (OCT) images obtained
from a diverse range of patients. Using robust augmentations and 5-fold
cross-validation, we trained two vision transformer-based models: MaxViT and
EVA-02, and ensembled them at inference time. We find MaxViT's use of
convolution layers followed by strided attention to be better suited for the
detection of local features while EVA-02's use of normal attention mechanism
and knowledge distillation is better for detecting global features. Ours was
the best-performing solution in the competition, achieving a patient-wise F1
score of 0.814 in the first phase and 0.8527 in the second and final phase of
VIP Cup 2023, scoring 3.8% higher than the next-best solution
Order and disorder - An integrative structure of the full-length human growth hormone receptor
Because of its small size (70 kilodalton) and large content of structural disorder (>50%), the human growth hormone receptor (hGHR) falls between the cracks of conventional high-resolution structural biology methods. Here, we study the structure of the full-length hGHR in nanodiscs with small-angle x-ray scattering (SAXS) as the foundation. We develop an approach that combines SAXS, x-ray diffraction, and NMR spectroscopy data obtained on individual domains and integrate these through molecular dynamics simulations to interpret SAXS data on the full-length hGHR in nanodiscs. The hGHR domains reorient freely, resulting in a broad structural ensemble, emphasizing the need to take an ensemble view on signaling of relevance to disease states. The structure provides the first experimental model of any full-length cytokine receptor in a lipid membrane and exemplifies how integrating experimental data from several techniques computationally may access structures of membrane proteins with long, disordered regions, a widespread phenomenon in biology
Eurasian globalization: past and present
© 2020 Informa UK Limited, trading as Taylor & Francis Group. In an attempt to examine Eurasian globalization historically, this paper outlines three phases of globalization starting from 200 BCE to 1492 CE as Phase 1 and 1500 CE to 1999 CE as Phase 2 and from 2000 CE Phase 3. By historicizing the concept and the process of globalization, the paper attempts to provide a more global rather than a Europe-centred history of globalization and modernization. The paper builds on the idea of Eurasia and offers a new perspective of Eurasian globalization by pivoting on China\u27s role in both Phase 1 and Phase 3 of globalization. The paper uses historical literature that has been not only critical of the Eurocentric view of the world but also provides a more connected view of global history. Concurring with Steger and James [2019. Globalization matters. Cambridge University Press] that globalization has not outlived its utility, the paper seeks to historicize and globalize the discussion of globalization
Local political consolidation in Bangladesh: power, informality and patronage
During the past decade Bangladesh has shifted from a competitively clientelistic twoâparty system towards a dominantâparty democracy. This article analyses how the ruling party has consolidated partisan political control at the local level. Using qualitative field data from 2004 and 2016, and drawing on a postâstructural analysis of the state, it shows how this extension of power has been achieved locally through interaction between formal and informal political initiatives. Four main types of informal activity are documented, through which the extent of local political competition has been reduced: circumvention, capture, brokerage and the creation of new organizations. These insights into the changing nature of Bangladesh's longâstanding partisan politics highlight how the state's capacity to deliver local services, allocate resources and maintain stability has been enhanced through the ruling party's control of local government structures, its elimination of political opposition, and its reshaping of local patronage arrangements
