Symbolic Racism or Self-Interest? Comparing Rural and Urban Worries about Obamacare  [PDF]
Theresa Davidson
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.66019
Abstract: Framed by the theory of symbolic racism versus self-interest, this study sought to investigate differences, if any, between rural and urban residents’ concerns about Obamacare (the Affordable Care Act). First, we found that rural residents are significantly more worried about Obamacare. Second, regarding symbolic racism, ratings of Muslims (but not blacks or immigrants) predicted worry about Obamacare for rural and urban respondents. Third, different self-interest measures were predictive for the rural and urban samples. Rural residents who worried about becoming ill were more worried about Obamacare. Urban residents who worried about money were more worried about Obamacare. We conclude with recommendations for framing health care reform in ways that might reduce concerns among rural and urban people.
Dendritic mRNAs encode diversified functionalities in hippocampal pyramidal neurons
Jun Zhong, Theresa Zhang, Lisa M Bloch
BMC Neuroscience , 2006, DOI: 10.1186/1471-2202-7-17
Abstract: We have identified 154 dendritic mRNA candidates, which can be arranged into the categories of receptors and channels, signaling molecules, cytoskeleton and adhesion molecules, and factors that are involved in membrane trafficking, in protein synthesis, in posttranslational protein modification, and in protein degradation. Previously known dendritic mRNAs such as MAP2, calmodulin, and G protein gamma subunit were identified from our screening, as were mRNAs that encode proteins known to be important for synaptic plasticity and memory, such as spinophilin, Pumilio, eEF1A, and MHC class I molecules. Furthermore, mRNAs coding for ribosomal proteins were also found in dendrites.Our results suggest that neurons transport a variety of mRNAs to dendrites, not only those directly involved in modulating synaptic plasticity, but also others that play more common roles in cellular metabolism.Neurons are highly polarized cells with extensive processes and thousands of synapses sharing one nuclear genome. The ability to supply specific gene products to a distant synapse is crucial for neuronal functions. Although proteins can be made in the cell body and transported to synapses, local synthesis of proteins from dendritic mRNAs provides an efficient mechanism for delivering synaptic proteins where and when they are needed. It has become evident that mRNAs are transported to the dendrite and translated locally near the synapse following the discovery of synapse-associated polyribosome complexes (SPRCs) [1], and local protein synthesis has been demonstrated following synaptic activation [2-8]. Local protein synthesis is important for long-lasting synaptic plasticity and memory, as locally applied protein synthesis inhibitors block branch-specific long-term facilitation in Aplysia neuronal cultures [9], and deletion of the dendritic-targeting element in CaMKIIα mRNA impairs synaptic plasticity and memory consolidation [10]. Given the importance of dendritic RNA transport and local p
Decision Making in International Tertiary Education: The Role of National Image  [PDF]
Jing Cai, Theresa Loo
Advances in Journalism and Communication (AJC) , 2014, DOI: 10.4236/ajc.2014.23012
Abstract: The purpose of this paper is to explore the influence of the national image on the image of its tertiary education among non-nationals and on their choice of location for study. We present a conceptual model of how the image of the nation impacts on the image of tertiary education based upon Ajzen & Fishbein’s (1980) “theory of reasoned action”. With data from China & India, a model is developed from a calibration sample and tested against a validation sample using structural equation modelling. The model fits the data well and shows that a national image for Chic (prestigious, refined, elegant) and Enterprise (innovative, cool, trendy) has a positive influence on the beliefs about, attitudes towards and propensity to consume tertiary education offered by the UK. Our work indicates that there will be mileage in investing not just on the image of education itself, but on the image of the nation in the promotion of international tertiary education.
Fraud spurs Cell paper retraction
Theresa Tamkins
Genome Biology , 2003, DOI: 10.1186/gb-spotlight-20040213-02
Abstract: "Although the data caused a stir, I think most people's view was that there was some interpretation problem early on, so it really hasn't dramatically changed most people's thinking," said Xi He, of Children's Hospital Boston and Harvard Medical School. "I think it is a bump in the Wnt field, but it has not moved the field several years backwards."Gary Struhl of the Howard Hughes Medical Institute (HHMI) and Columbia University in New York retracted the paper from Cell on February 6. The paper, published in 2002, challenged the conventional theory on Wnt signaling.Wnt protein is thought to bind to its receptor, setting off a signaling pathway in which beta-catenin (or Armadillo in the fruit fly) enters the nucleus and activates transcription factors. Struhl and postdoc Siu-Kwong Chan argued in the paper that Armadillo can be tethered to the membrane and transduce Wnt signals without entering the nucleus.When Struhl recently attempted to replicate the experiments, which were largely conducted by Chan, he "personally obtained the opposite result for the key negative control for the experiments in Figure 5," he writes in the retraction. When confronted, Chan reported that some of the results were "either not performed or gave different results than presented in the paper," according to the retraction.Struhl declined to elaborate further."The retraction says it all," he said in an E-mail message. "Columbia and HHMI have mandated protocols to investigate misconduct when it occurs. I contacted Columbia, HHMI, and Cell Press immediately upon discovering that crucial experiments in the paper had been fabricated." Columbia and HHMI are investigating the incident, Struhl said.Chan, who was at Albert Einstein College of Medicine since November 2003, resigned from his position on January 21. He could not be reached for comment for this article.The retraction coincides with a paper published February 10 in Public Library of Science (PLoS) Biology, in which Princeton University's
A Predictable Unpredictability. The 2009 H1N1 pandemic and the concept of “strategic uncertainty” within global public health
Theresa MacPhail
Behemoth : a Journal on Civilisation , 2010,
Abstract: This essay will examine the seemingly new paradigm shift within global public health from the use of a scientific “certainty” to a biological and situational “uncertainty” as one of the foundations of response to infectious disease outbreaks. During the recent 2009 H1N1 influenza outbreak, national and international public health officials often referred directly to the “uncertainty” surrounding both the virus itself and of the course, duration and severity of the pandemic. The vague and flexible concept of “uncertainty” – especially as it was employed by top virologists and epidemiologists in relationship to questions about the predictability of the influenza virus – provided the scientific foundation for much of the rationale behind both national and international health responses to the global pandemic. Public health officials, epidemiologists, and scientists often deployed a type of “strategic uncertainty” as an effective tool for gaining or retaining trust and scientific authority during the H1N1 pandemic.

H ftlinge im Frauenkonzentrationslager Ravensbrück The Ravensbrück Concentration Camp for Women
Theresa Reinold
querelles-net , 2002,
Abstract: Im Zentrum der Arbeit von Christa Schikorra steht die Frage nach den Mechanismen gesellschaftlicher Ausgrenzung asozialer“ Frauen – zur Zeit des Nationalsozialismus, aber auch in der Nachkriegszeit. Wenn auch die Zugeh rigkeit zur Gruppe der Asozialen“ erst im Nationalsozialismus lebensbedrohlich wurde, so lassen sich in der Stigmatisierung und Ausgrenzung von Menschen, die mit dem Etikett asozial“ versehen wurden und werden, gesellschaftliche Traditionslinien erkennen, die schon vor dem Nationalsozialismus wirksam waren und es bis heute sind – so die These der Autorin. Ihre Analyse fragt nach der Entstehung des Stigmas asozial“: Auf welche Vorurteilsstrukturen und Stereotypen gründet eine solche Kategorisierung? Wer tr gt zu ihrer Entstehung bei, d.h. wer sind die Akteure gesellschaftlicher Ausgrenzung? Welche Rolle spielen der Staat und seine Institutionen? Wie funktioniert Normsetzung, und wie manifestiert sich diese? Bezogen auf die konkreten Lebensgeschichten asozialer“ Frauen fragt Schikorra nach dem Leben vor der Haft, nach der Verfolgungsgeschichte, den Erfahrungen im Konzentrationslager, der Stellung in der H ftlingsgesellschaft sowie dem Leben nach dem Umgang mit Ausgrenzung und Benachteiligung auch nach 1945. Concentration camps were instruments of discriminiation and segregation (and, eventually, instruments of extermination). Similarly, research on concentration camps and attempts at coming to terms with this part of German history have fallen prey to discrimination and stigmatization directed against certain groups of victims and survivors. This review introduces two new publications which aim to direct the readers’ attention to long neglected research topics. Both works put those who were persecuted and placed in concentration camps at the centre, rendering visible the experiences and stories of those who had been ignored thus far. Both books deal with the women’s concentration camp, Ravensbrück. Schikorra examines on the particularly difficult situation of those prisoners who had been categorised as “anti-social.” Amesberger and Halbmayer, on the other hand, focus on the fate of Austrian inmates.
