    How to Look Like a Lesbian Without Even Trying

    Full text link
    “Ugh. I hate those pictures. I look like such a lesbian in them,” my cousin explained to me while her family and I sat around their kitchen table. After she said this, her younger brother laughed into his chicken noodle soup and she hit him over the head. “Shut up. I’m telling you. They’re so bad,” she said. As the conversation went on, I learn that she was referring to pictures that had been taken at one of her lacrosse practices. The important part is that she was displeased with the photos. And it’s certainly not because someone had caught her in a tryst with a woman and taken pictures of the incident. [excerpt

    You Can\u27t Always Get What You Want

    My parents used to tell me that I wasn’t entitled to anything—that I should be happy with what I have and not assume that I deserved something unless I had worked for it. Either way, entitlement is something that I’ve been thinking about a lot lately. So what do I think I’m entitled to? I’m not really sure. Maybe I’m entitled to making my own choices about what I’m going to do after graduation or having friends that treat me well. Maybe not. [excerpt

    Gay After Graduation

    Full text link
    I first went public with my sexual orientation over Surge last spring–my last semester at Gettysburg before graduation. I was scared, but ultimately lucky to be met with support from my friends and family. People generally accepted my sexuality and then moved on. Actually, life went on so quickly that it took me some time to catch up. [excerpt

    Mobile Activism: What Your Profile Picture Says About You

    Full text link
    I know you’ve all been seeing this image all of your Facebook news feeds. All of the sudden a few weeks ago it became everyone’s profile picture. People were sharing it, along with other images, explaining why Prop. 8 and the Defense Of Marriage Act should be repealed, and were generally expressing their support of marriage equality. [excerpt

    Propeller propulsion integration, phase 1

    Get PDF
    A bibliography was compiled of all readily available sources of propeller analytical and experimental studies conducted during the 1930 through 1960 period. A propeller test stand was developed for the measurement of thrust and torque characteristics of full scale general aviation propellers and installed in the LaRC 30 x 60 foot full scale wind tunnel. A tunnel entry was made during the January through February 1980 period. Several propellers were tested, but unforseen difficulties with the shaft thrust torque balance severely degraded the data quality

    Hemoglobin Alc: Structure, Biosynthesis and Clinical Significance In Diabetes Mellitus

    Diabetes mellitus is a chronic metabolic disorder characterized by abnormally high blood glucose concentrations and a relative or absolute deficiency of insulin. Approximately 5 per cent of the American population are afflicted with this disease, which is a leading cause of morbidity and mortality in the United States today. Diabetes may result in the dysfunction of many different organ systems, yet the biochemical mechanism(s) underlying these dysfunctions is unknown. Even the importance of hyperglycemia in the development of the sequelae of diabetes is unsettled. One of the metabolic abnormalities known to characterize this disease is an increase in the peripheral blood concentration of hemoglobin Alc. This minor red cell component comprises 3-5 per cent of the total hemoglobin in non-diabetic humans but up to 15 per cent in diabetics. There is evidence to suggest that it is a glycosylated derivative of hemoglobin A. The aim·of these investigations has been to increase our understanding of the significance of increased hemoglobin Alc concentrations in diabetics. The studies described here in the diabetic mouse demonstrate increased hemoglobin Alc to be a marker for the diabetic phenotype regardless of the cause of diabetes. The increase in hemoglobin Alc concentration occurs 3-4 weeks after the onset of diabetes. Hemoglobin Alc is made as a post-synthetic modification of hemoglobin A at a constant slow rate throughout the life of the red cell. In diabetic humans, hemoglobin Alc concentration correlates with the severity of disease. Changes in the quality of diabetic control are followed, after a 3-4 week delay, by proportionate changes in hemoglobin Alc concentration. Hemoglobin Alc concentration reflects the mean blood glucose concentration for the 3-4 weeks prior to the measurement. Thus, infrequent hemoglobin Alc measurements would be sufficient to assess the quality of long-term diabetic control, a feature unique to this measurement. The periodic monitoring of hemoglobin Alc concentration should permit patients to achieve better diabetic control than is currently possible and should make it possible to determine whether hyperglycemia is important in the development of the sequelae of diabetes. The structure of hemoglobin Alc is identical to that of hemoglobin A, with the addition of l-deoxy fructose attached at the amino terminus of the B chains. The increased formation of hemoglobin Alc in diabetes is an example of the increased glycosylation of a protein (hemoglobin A) occurring in this disease process. The biosynthesis of hemoglobin Alc provides a conceptual framework that may explain the molecular basis for many of the sequelae of diabetes. Thus, the abnormal or excess glycosylation of other proteins may cause structural or functional changes in those proteins and thereby result in the diverse sequelae known to occur secondary to this disease

    Comparing Effectiveness Of Undergraduate Course Delivery: A Student Perspective

    Get PDF
    Higher education students can and do take courses delivered in a variety of ways. But, to date, little research has been done on the effectiveness of different delivery modes.  This study sought to fill that void by comparing the effectiveness of three undergraduate course delivery modes: classroom, online, and video conference at a technical institute in a mid-Atlantic state. Students (N = 1,206) completed questionnaires on effectiveness, in terms of satisfaction, for each mode and on demographic characteristics. The questionnaire response rates were 74% for students.   In terms of student satisfaction, the results revealed that classroom delivery was more effective than technologically delivery with online being slightly more effective than video conference.  The results of this research should assist leaders in higher education to understand the benefits associated with different undergraduate course delivery modes. In addition, the study provides leaders with a useful tool for securing and applying this type of information when making decisions about the modes best suited to serve their academic communities
