Mental Health Effects on Young Athletes: A Comprehensive Review

Just like physical health, mental health is important for any young athlete. Significant focus on mental health is imperative, as mental illness continues to rise in individuals ages 10-24, in addition to the demands that come with playing a competitive sport. The purpose of this review of literature was to observe how mental health affects young athletes and their methods of seeking help. Statistics have shown that mental health has taken a toll on younger populations in recent years, and it is important to consider how the components of being an athlete can weigh in. Methods throughout these studies consisted of various scales, surveys, and questionnaires to research how mental illnesses such as depression and anxiety have an effect on young individuals who participate in sports, and specifically their outlook towards receiving help they may need. Results showed that there are significant differences of mental health concerns between athletes and non-athletes, especially when there are other factors such as academics involved. Stigmas attached to mental health also showed to be a concern when it came to seeking counseling services, and many said that positive attitudes from figures like coaches would help. This review can be useful for implementing mental health programs and services designed specifically for athletes, and for bringing more awareness to this issue

Frequency-domain waveform approximants capturing Doppler shifts

Gravitational wave astrophysics has only just begun, and as current detectors are upgraded and new detectors are built, many new, albeit faint, features in the signals will become accessible. One such feature is the presence of time-dependent Doppler shifts, generated by the acceleration of the center of mass of the gravitational-wave emitting system. We here develop a generic method that takes a frequency-domain, gravitational-wave model devoid of Doppler shifts and introduces modifications that incorporate them. Building upon a perturbative expansion that assumes the Doppler-shift velocity is small relative to the speed of light, the method consists of the inclusion of a single term in the Fourier phase and two terms in the Fourier amplitude. We validate the method through matches between waveforms with a Doppler shift in the time domain and waveforms constructed with our method for two toy problems: constant accelerations induced by a distant third body and Gaussian accelerations that resemble a kick profile. We find mismatches below $\sim\!10^{-6}$ for all of the astrophysically relevant cases considered, and improve further at smaller velocities. The work presented here will allow for the use of future detectors to extract new, faint features in the signal from the noise.Comment: 11 pages, 5 figures, submitted to Phys. Rev.

"A Just and Honest Valuation": paper money and the body politic in colonial America, 1640-1765

My dissertation argues that paper money created a new regime of value in early America, inscribed on the money itself and expressed in the political ordering of society. The radical ideas about money and value that inspired the colonial currencies originated in Commonwealth England. Those ideas spread to the North American colonies after the Restoration, where they conveyed changing notions about membership in the political community. Paper money, its proponents believed, constituted not only the “sinews” of trade and key to limitless wealth but also the “blood” that nourished the body politic. Ironically, the expansion of paper money in early America after 1710 both reflected and helped kindle broader material and cultural changes throughout the wider English Atlantic world that strained the bonds of the provincial political community. Ultimately, however, it was not these changes, but British attempts to control paper money in the mid-eighteenth century, that became corrosive to the imperial order. Disagreements over the prerogative to create money and value, I contend, occupied a key role in the crisis leading to the American Revolution.2020-02-14T00:00:00

Knowledge Sharing and Customer Relations in Mobility

After the events of September 11, 2001, inadequacies in how government organizations and agencies shared knowledge and communication with defense mission partners became readily apparent. A reasonable U.S. government information technology expectation is the integrated use of mobile phones across organizations and agencies. Yet, it is difficult to meet this expectation, as the provisioning process for mobile devices can be different for each government organization or agency. The Department of Commerce National Institute of Standards and Technology does not set provisioning standards, and organizations and agencies determine policies tailored to their particular needs. Using Schein\u27s theory on organizational culture, the focus of this phenomenological study was to explore the Mobility provisioning process from the experiences of government customer support personnel. Eleven personnel responded to 10 semistructured interview questions derived from the research question. The data were manually transcribed and then coded, arranged, and analyzed using a software tool. Three major themes emerged from the analyzed data: (a) expand communication with customers and leaders, (b) identify policy guidelines, and (c) streamline and centralize the process. Using these themes, recommendations include enhancing communication among stakeholders, provisioners, and Warfighters, soldiers in the field; implementing standardized user policies; and improving cross-organization and cross-agency provisioning processes. Social change actions include increasing mobility provisioning efficiencies among provisioners, which not only saves time and money, but also provides Warfighters with affordable, dependable, and reliable mobile communications systems

From the Ouachitonian : Kevin Merino

The Ravine Rovers began their journey during the first semester of the 2021-2022 academic year at Ouachita as a group of students looking for an organized league in which to play soccer. The team was initially created by Kevin Merino, a senior biology major from Wylie, Texas, and Logan Daust, a senior business administration/sport management major from Plano, Texas

Patrick’s Point State Park Habitat Restoration Plan

Ongoing efforts at Patrick’s Point State Park (PPSP) seek to restore the ecosystems contained therein. Over time, non-native invasive plant species have become established within the Park. This habitat restoration plan (or Plan) aims to aid in restoring native and sensitive habitat through the removal of non-native invasive species. The Plan will take many different approaches to targeting the invasive non-native plant species depending on the target species and specific site conditions

Scalable and controlled presentation of surface immobilised factors from the bone marrow niche for hematopoietic cell expansion

Umbilical cord blood provides a source of hematopoietic stem cells for transplantation with immunological and availability advantages over conventional bone marrow sources. Limited cell numbers and slower engraftment from umbilical cord blood units has led to the clinical development of immobilised Notch ligand Delta-Like 1 to promote ex vivo expansion of a rapidly engrafting cell population. Further, bone marrow stromal cells also promote ex vivo proliferation and differentiation of hematopoietic stem cells, supporting the concept that bone marrow niche cues may influence their fate. Surface receptors for a number of proteins released from the bone marrow niche have been identified on hematopoietic stem cells. The immobilisation of these niche proteins in a controllable manner presents an exciting opportunity for the improved expansion of cells with high clinical potential. The aim the work was to demonstrate the biological function, and integration with a scalable system, of a highly controllable immobilised protein approach. A micro-scale stirred tank bioreactor platform (ambr®; Sartorius Stedim, UK.) was used to determine the scalability of the immobilisation method. Initial studies were carried out using Delta-Like 1. Delta-Like 1 was immobilised onto streptavidin coated magnetic particles via a heterobifunctionalised polyethylene glycol linker molecule. CD34+ cord blood cells were treated with Delta-Like 1 immobilised particles, and phenotype markers measured to monitor population distributions using spanning tree progression of density normalised events software. Surface concentration of Delta-Like 1 was simply controlled via reagent concentration and beads could be efficiently removed from static or stirred experimental systems. Immobilised Delta-Like 1 is functional and stimulates qualitatively similar lineage skewing toward high expressing CD34 CD133 CD33 myeloid progenitors in both static and stirred culture platforms. We have further demonstrated the controlled immobilisation of seven further niche proteins, sonic hedgehog, delta-like 4, jagged 1, jagged 2, bone morphogenetic protein 2, bone morphogenetic protein 4 and wingless MMTV integration site 3A, alongside 4 hematopoietic relevant cytokines. Immobilised niche proteins have the potential to improve the manufacturing efficiency and control of final ex vivo expanded cell products through compatibility with highly controlled and characterised suspension culture systems and scalable surface volume ratios
