Latinx Internship Prepa: An Experiential Career Readiness and Preparation Program for Latinx, First-Generation Undergraduate College Students

Access to higher education has increased within the last decades, particularly within historically underserved communities, but the challenges of navigating college for first-generation Latino/a/x students still show up in the disproportionate rates of retention, persistence, and graduation for this group (National Center for Education Statistics, 2019). High-impact practices have shown to promote student retention and help close the achievement gap for underrepresented students. More specifically, internships and experiential learning activities play an important role in aiding students\u27 careers, academic major, and self-exploration. For first-generation college students, engaging with higher education institutions through these practices often leads to better academic outcomes and an increase in persistence and retention (Conefrey, 2021). Additionally, professionals of color who work at higher education institutions serve as mentors for students of color and often play a large role in the engagement of this community of students. These faculty and staff of color, when working with students, consider the background and identities as well as their social and cultural capital that this specific student population is bringing with them to a college campus, and in many cases provide more resources and support than what their role entails (Luedke, 2017). During the Coronavirus Disease 2019 (COVID-19) pandemic, a virtual internship preparation and readiness program, Latinx Internship Prepa, was created and launched during the Summer 2020 semester and again in the Fall 2020 semester. The Latinx Internship Prepa program was designed to provide already existing campus resources and services, such as the Career Center and Writing Center, in a structured 5-week student program. The program also provided guidance on accessing and scheduling the use of these services for first-generation Latinx students and providing a direct connection with staff members in these offices. Participating students were provided with career development tools (e.g., resume building, cover letter writing, and LinkedIn branding tips) as well as experiential activities (mock-interviews and presentation delivery practice) to assist these students with applying and interviewing for national and competitive internships and other experiences such as fellowships and clinicals. Professionals of color and/or first-generation professionals were invited to participate in this program by delivering career readiness content through presentations and engaging activities, in addition to leading individual and group mock-interviews with students. Feedback was considered from the summer session, in which students requested more peer interaction and practice of presentation skills. As a result, in the fall semester, a group presentation over a professional development topic of their choosing was added as an additional activity. This article focuses on the experiences of Latinx, First-Generation undergraduate college students who participated in a 5-week online synchronous internship preparation and readiness program. A secondary data set was used in which 18 students during the summer 2020 session and an additional 7 students during the fall 2020 session responded to both qualitative and quantitative questions. Analyses of the data yielded themes that can inform students’ academic and professional planning and future programs to continue to incorporate cultural representation and more intentional support

Rapid fabrication and characterization of sine wave targets

The effect of surface perturbations on Inertial Confinement Fusion target performance is currently being researched at Los Alamos National Laboratory (LANL). These perturbations can cause hydrodynamic instabilities which in turn reduce the targets` yield. To systematically measure the growth of these instabilities requires targets to be produced which have perturbations of a known amplitude and spatial frequency. The authors have recently assembled hardware onto one of their diamond turning lathes which enables them to machine and measure these sine waves in about 15 minutes. This is a significant reduction in time from the two and one half hours required by the previous method. This paper discusses the hardware, how it works, and how well the system is working for them to produce these targets

Large CSC chamber for the PHENIX muon detector with ultra thin cathode foils

The muon tracking system for the PHENIX detector at RHIC uses cathode strip chambers (CSC) for the tracking detectors. These detectors must provide 100 μm resolution per measurement plane to give satisfactory mass resolution of the vector mesons. The intermediate station (station 2) must have a very small radiation length, and large acceptance. We have prototyped a full scale CSC chamber to test the use of 25 micron metalized mylar foils for the cathode strips at station 2. The full scale prototype detector is a trapezoid 2.3 meters high and 2.3 meters wide. The foil and wire planes are mounted on thin 3,2 mm thick by 7.5 cm wide laminated frames and the tension of the planes is maintained by the two large 7.5 cm widex3.0 cm thick aluminum support frames. The total radiation length of the active region is 8.5x104

Mindfulness-based interventions for young offenders: a scoping review

Youth offending is a problem worldwide. Young people in the criminal justice system have frequently experienced adverse childhood circumstances, mental health problems, difficulties regulating emotions and poor quality of life. Mindfulness-based interventions can help people manage problems resulting from these experiences, but their usefulness for youth offending populations is not clear. This review evaluated existing evidence for mindfulness-based interventions among such populations. To be included, each study used an intervention with at least one of the three core components of mindfulness-based stress reduction (breath awareness, body awareness, mindful movement) that was delivered to young people in prison or community rehabilitation programs. No restrictions were placed on methods used. Thirteen studies were included: three randomized controlled trials, one controlled trial, three pre-post study designs, three mixed-methods approaches and three qualitative studies. Pooled numbers (n = 842) comprised 99% males aged between 14 and 23. Interventions varied so it was not possible to identify an optimal approach in terms of content, dose or intensity. Studies found some improvement in various measures of mental health, self-regulation, problematic behaviour, substance use, quality of life and criminal propensity. In those studies measuring mindfulness, changes did not reach statistical significance. Qualitative studies reported participants feeling less stressed, better able to concentrate, manage emotions and behaviour, improved social skills and that the interventions were acceptable. Generally low study quality limits the generalizability of these findings. Greater clarity on intervention components and robust mixed-methods evaluation would improve clarity of reporting and better guide future youth offending prevention programs

Search for the lepton-family-number nonconserving decay \mu -> e + \gamma

The MEGA experiment, which searched for the muon- and electron-number violating decay \mu -> e + \gamma, is described. The spectrometer system, the calibrations, the data taking procedures, the data analysis, and the sensitivity of the experiment are discussed. The most stringent upper limit on the branching ratio of \mu -> e + \gamma) < 1.2 x 10^{-11} was obtained

Freshwater ecoregions of the world: A new map of biogeographic units for freshwater biodiversity conservation

We present a new map depicting the first global biogeographic regionalization of Earth's freshwater systems. This map of freshwater ecoregions is based on the distributions and compositions of freshwater fish species and incorporates major ecological and evolutionary patterns. Covering virtually all freshwater habitats on Earth, this ecoregion map, together with associated species data, is a useful tool for underpinning global and regional conservation planning efforts (particularly to identify outstanding and imperiled freshwater systems); for serving as a logical framework for large-scale conservation strategies; and for providing a global-scale knowledge base for increasing freshwater biogeographic literacy. Preliminary data for fish species compiled by ecoregion reveal some previously unrecognized areas of high biodiversity, highlighting the benefit of looking at the world's freshwaters through a new framework.La lista completa de autores que integran el documento puede consultarse en el archivo.Facultad de Ciencias Naturales y Muse

Convergence of the steepest descent method for minimizing quasiconvex functions

To minimize a continuously differentiable quasiconvex function f : ℝ n →ℝ, Armijo's steepest descent method generates a sequence x k +1 = x k − t k ∇ f ( x k ), where t k >0. We establish strong convergence properties of this classic method: either , s.t. ; or arg min f = ∅, ∥ x k ∥ ↓ ∞ and f(x k )↓ inf f . We also discuss extensions to other line searches.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45245/1/10957_2005_Article_BF02192649.pd

Rapid spatiotemporal variations in rift structure during development of the Corinth Rift, central Greece

The Corinth Rift, central Greece, enables analysis of early rift development as it is young (<5Ma) and highly active and its full history is recorded at high resolution by sedimentary systems. A complete compilation of marine geophysical data, complemented by onshore data, is used to develop a high-resolution chronostratigraphy and detailed fault history for the offshore Corinth Rift, integrating interpretations and reconciling previous discrepancies. Rift migration and localization of deformation have been significant within the rift since inception. Over the last circa 2Myr the rift transitioned from a spatially complex rift to a uniform asymmetric rift, but this transition did not occur synchronously along strike. Isochore maps at circa 100kyr intervals illustrate a change in fault polarity within the short interval circa 620-340ka, characterized by progressive transfer of activity from major south dipping faults to north dipping faults and southward migration of discrete depocenters at ~30m/kyr. Since circa 340ka there has been localization and linkage of the dominant north dipping border fault system along the southern rift margin, demonstrated by lateral growth of discrete depocenters at ~40m/kyr. A single central depocenter formed by circa 130ka, indicating full fault linkage. These results indicate that rift localization is progressive (not instantaneous) and can be synchronous once a rift border fault system is established. This study illustrates that development processes within young rifts occur at 100kyr timescales, including rapid changes in rift symmetry and growth and linkage of major rift faults

The impact of positive psychological interventions on well-being in healthy elderly people

This systematic review aims to evaluate the impact of Positive Psychological Interventions (PPIs) on well-being in healthy older adults. Systematic review of PPIs obtained from three electronic databases (PsycINFO, Scopus, and Web of Science) was undertaken. Inclusion criteria were: that they were positive psychology intervention, included measurement of well-being, participants were aged over 60 years, and the studies were in English. The Cochrane Collaboration Guidelines dimensions of quality control, randomization, comparability, follow-up rate, dropout, blinding assessors are used to rate the quality of studies by two reviewers independently. The RE-AIM (Reach, Efficacy, Adoption, Implementation, and Maintenance) for evaluation of PPIs effectiveness was also applied. The final review included eight articles, each describing a positive psychological intervention study. The reminiscence interventions were the most prevalent type of PPIs to promote and maintain well-being in later life. Only two studies were rated as high quality, four were of moderate-quality and two were of low-quality. Overall results indicated that efficacy criteria (89%), reach criteria (85%), adoption criteria (73%), implementation criteria (67%), and maintenance criteria (4%) across a variety of RE-AIM dimensions. Directions for future positive psychological research related to RE-AIM, and implications for decision-making, are described
