Process for making a noble metal on tin oxide catalyst

A quantity of reagent grade tin metal or compound, chloride-free, and high-surface-area silica spheres are placed in deionized water, followed by deaerating the mixture by boiling and adding an oxidizing agent, such as nitric acid. The nitric acid oxidizes the tin to metastannic acid which coats the spheres because the acid is absorbed on the substrate. The metastannic acid becomes tin oxide upon drying and calcining. The tin-oxide coated silica spheres are then placed in water and boiled. A chloride-free precious metal compound in aqueous solution is then added to the mixture containing the spheres, and the precious metal compound is reduced to a precious metal by use of a suitable reducing agent such as formic acid. Very beneficial results were obtained using the precious metal compound tetraammine platinum(II) hydroxide

Preparing Tomorrow’s World Language Teacher Today: The Case for Seamless Induction

This essay is a call to action. It offers a comprehensive overview of the challenges facing world language (WL) teacher educators and their employers, the K-12 schools, during the teacher induction period. We propose a new paradigm for WL teacher education based on national accreditation standards, best-practice pedagogy, insights from the professional literature on methods education, and the enhanced role of the methods instructor/supervisor. In order to become successful in the classroom, the pre-service educator undergoes a seamless period of induction that is student-centered and college/university-supported beyond the classroom arena

Perceptions of Criminality: An Experiment on Race, Class, and Gender Stereotypes

The study of perceptions of criminality is significant in sociology due to its sociopolitical implications for our criminal justice system. Race, class, and gender disparities in this system influence prejudices in the American public, which in turn allows the perpetuation of inequality. Using an intersectional approach, this research seeks to interpret how race, class, and gender intersect to create and shape perceptions of criminality. Conducting an experiment on approximately 500 undergraduate students at a southern university during the Spring 2015 semester, subjects are shown a series of photographs and asked to select who, out of the individuals depicted, they believe to be criminals. Findings suggest that perceived class is a strong determinant of criminality, with race and gender effects as well. This study proposes that results are shaped by the workings of the criminal justice system, media portrayals of criminals, and the particular significance of our current social and political environment

The resilience of a London Great Estate: urban development, adaptive capacity and the politics of stewardship

This paper explores the concept of resilience through the planning, development, and management history of one of London’s Great Estates. The Grosvenor Estate in Mayfair and Belgravia was developed incrementally from the 1720s and continues to be managed on behalf of the aristocratic Grosvenor family. The Great Estates have been described as exemplars of effectively managed evolution in response to change in several non-academic publications and resilience acquired a strategic significance for Grosvenor in the early twenty-first century. This occurred in the context of the phenomenon of empty homes acquired by overseas investors which has steadily transformed the character of inner London areas, but also related to Grosvenor’s management future. The paper argues that the Grosvenor Estate provides an intriguing case for testing academic ideas of ‘evolutionary resilience’ while also raising issues of how resilience concepts are mobilised within the socio-political worlds of planning, development, and real estate management practice

The United States Medical Licensing Exam (USMLE) and medical student wellness: an ethnographic qualitative study at Cooper Medical School of Rowan University

Research indicates that medical students experience unusually high levels of stress, anxiety, depression, and loss of empathy while in medical school. As the number of medical students rises and residency positions remain stagnant, the USMLE receives greater emphasis as a barometer to determine residency placement and future career paths thereby increasing levels of stress among students. Stress is associated with diminished self-care, potentially leading to a negative impact on well-being. This ethnographic, qualitative study sought to examine the extent to which the anticipation of, preparation for, and implications of the USMLE contribute to medical student stress, wellness, and self-care. Through forty-four interviews combined with immersed observation, and multiple brief interactions with medical students, faculty, and staff at Cooper Medical School of Rowan University, the impact of the USMLE on the health and well being of medical students was assessed. Results clearly indicated that the USMLE adversely affects medical student wellness, particularly depleting physical, social, and psychological well-being. While a few students were able to successfully manage through the exam preparation, the vast majority decreased or depleted their coping reservoir over the course of USMLE preparation exhibiting emotional, social, and physical ramifications

Uncle Sam\u27s Lesbians: Power, Empowerment, and the Military Experience

Why would a lesbian choose to go into an androcentric, mysogynist environment, and, once there, choose to stay? This study examines the military experience of lesbians as represented by a group of twenty-two lesbian veterans and active duty military personnel. This research concentrates on three basic areas of concern: recruitment, retention, and the structure and function of personal networks. The results show many similarities between this group of women and those in other studies on women in the military with regard to reasons for joining the military and background information. However, these results also indicate a connection between being gay and joining the military, and a very strong correlation between sexual orientation and forming exclusive networks in the military

Don\u27t Worry

When I was really young something at the core of my being whispered to me, “she won’t live very long.” At the time I didn’t know where that voice was coming from, but I knew it was true. It was unsettling. Over the years I realized that I was being prepared for the eventuality of my mother’s death and that I wouldn’t know when or how it would happen. When it did occur, suddenly I knew there was nothing between death and me but time. This thought has haunted me to the point that I have developed a fear of my body. Advisor: Karen Kunc Death is a mystery – a reality and yet an unknown. It is an abstract concept that we push away and think we do not have to deal with until later. We indirectly understand death in terms of loss and absence, but ultimately we are aware of this concept of death through the vulnerability of our bodies. Living with that awareness is a delicate balance between fear and hope. As an artist, my process of making is an embodiment of that balance. I confront my vulnerability through the act of mark making. I allow the act of drawing to be a meditative state where I transfer my anxiety to the surface of the paper. The paper becomes a reference to the body as a site of ambiguity – a space of physical and psychological tension activated by transference, strength, construction and dissolution. Erasing, incising, rubbing, scratching and spilling create smooth and roughened surface textures that speak of the struggle of the physical body. I create a place of psychological tension by reworking and repeating these processes to make elemental shapes and details. The imagery often grows out of my gestures and the way the materials are applied. Forms and marks appear to be bending, stretching, floating away, separating, isolated, oozing, joining, and colonizing. What results is an imagined space that could be interpreted as of the body and or the mind, but the exact subject of the imagery is hidden. This allows me to create a contemplative experience that is seductive and unsettling and allows space for the viewer to interpret the imagery. Like entering a darkened room, the viewer needs time to adjust and re-adjust to this environment. By doing so, they become immersed in the rich nuances of the surfaces that are simultaneously visual and physical. Details are seen and secrets moments can be found. The phrase “don’t worry” is often said or thought to reassure that all will be okay, and yet it’s ironic. If repeated over and over, “don’t worry” goes from being a calming mantra to a low humming anxiety – a reminder that something is wrong. As a child I used to tell my mother, “Don’t worry so much,” but I had no idea what those words really meant. Now that I am older, I often find it impossible to not worry; I wonder how much is learned behavior and how much is genetic. The title of the exhibition and each piece form a poem, reminding us of the reality and need for hope. Through this work, I have realized that until I take my last breath, I will be discovering what my body is and what it can be – a vessel in a state of constant change, vulnerable, seeking comfort and relief. Don’t worry; let it go

Refugee Livelihood: Understanding the Vocational Training Experiences of Foreign Refugee Women Living in Malawi

With Africa holding 26% of the world’s refugees, it is critical to understand the educational opportunities that are accessible for refugees, especially in the context of African women who are historically excluded as the primary target for education (UNHCR, 2018a).Despite the policies and institutional commitment to education for the refugee population, there is little evidence to ensure quality, or access to education, at the regional or local levels. For women and young girls in displacement, access to education is particularly limited to the secondary level (UNHCR, 2011a).In response to the need for quality education for refugee women, Malawi’s vocational training and secondary education institutions have centered on activities to increase opportunities for formal secondary education of both refugee and Malawian women (UNESCO, 2008). As opportunity and awareness of quality secondary education for refugee women becomes more prevalent, there is a need to understand how these programs have influenced their sense of livelihood. For these reasons, this study explored the individual experiences of African refugee women focusing on how their experiences in completing a vocational training program have influenced their lives in terms of self-efficacy and empowerment in creating a livelihood. Findings of this study revealed participant livelihood experiences were influenced in varying degrees as a result of their vocational training. Vocational training was perceived by participants as a positive influence on livelihood capabilities as well as their positive feelings of self-efficacy and empowerment. However, education alone was only part of these outcomes, as other experiences of relationship building, creating alternative solutions for income-producing activities, and sharing their knowledge also influenced their feelings of self-efficacy and empowerment

Combined Scale Weight, Height at Hips and Visual Condition Score as an Indicator of Functional Body Size in Range Cows

Thirty-five range cows of various breeds were obtained for the study. Body measurements taken were live weight and hip height and all cows were condition scored for level of fatness. The cows were slaughtered and the following morning several carcass measurements were taken and the plate was removed from the left side. These plates were boned and the remaining flesh ground for chemical analysis of percent carcass fat. Regression equations were calculated for estimating percent carcass fat from condition score, weight:height ratio and hip height (R2=.765). However, condition score alone is the single best estimator for percent carcass fat (R2=.759)
