No full textEquifax: Understanding Its Actions through Situational Crisis Communication Theory
No full textabstract: The Equifax data breach took place in 2017 and was the largest data breach of its time. The breach affected 143 million individuals and caused large amounts of confidential and sensitive data, such as credit cards, birthdays, addresses, and social security numbers to be stolen (Brinkley-Badgett, 2018). This paper will closely analyze the Equifax data breach. Specifically, Equifax’s background, crisis history, and breach timeline will be broken down. These three components are all important when it comes to understanding Equifax’s actions. Timothy Coombs is a founder of Situational Crisis Communication Theory, and his interpretation of the theory will be used as a framework for this paper. Both his book, Ongoing Crisis Communication and article, Protecting Organization Reputations During a Crisis: The Development and Application of Situational Crisis Communication Theory, will be heavily referenced. Using Situational Crisis Communication Theory (SCCT) as a framework, these components will be assessed and categorized. “SCCT provides a mechanism for anticipating how stakeholders will react to a crisis in terms of the reputational threat posed by the crisis” (Coombs, 2007). By identifying the crisis type and crisis response strategies, Equifax’s actions will be analyzed and measured. The size, timeline, and media response will help identify what type of crisis Equifax falls into, and why their actions caused them to be categorized so. After analyzing the Equifax data breach, two other breaches will be analyzed and compared. The comparison of Equifax to Capital One and Home Depot, will help determine how Equifax could have been more effective through crisis response strategies. Capital One and Home Depot are two data breaches that were able to implement “effective” uses of crisis management and meet consumer expectations. Through the comparative analysis, recommendations as to what Equifax could have done differently will be made. The comparisons of their crisis type, actions, and response strategies will help shape recommendations for Equifax’s past crisis
The Rohingya Muslims: a Burmese folk devil
No full textStarting August 25, 2017, the Burmese military began a retaliatory campaign triggered by a handful of militant Rohingya insurgency attacks on Burmese law enforcement posts in the Northern Rakhine State in Myanmar. The military conducted a violent crackdown upon Rohingya men, women, and children, forcing over 700,000 Rohingya to flee to refugee camps in Southeast Bangladesh. Rohingya refugees fled massacres, gang rapes, torture, and arson of entire villages. Allegations of genocide and crimes against humanity are presently under investigation before two international courts.
This study investigates the complex sociohistorical context and conditions that converged over time in Myanmar, preceding the military-led mass atrocities of 2017, leaving the Rohingya population at acute risk of harm. I inquired how the Burmese military readily succeeded in this task, with widespread Buddhist civilian approval and sometimes even assistance. To explain the processes that led to the military’s successful expulsion of the Rohingya, I utilize multiple methods of qualitative data analysis. I begin with a historiographic analysis to establish a historical knowledge baseline. Then, I conduct critical discourse analyses of two strains of Burmese nationalism, traditional and religious. I conduct two additional analyses using data from 52 in-depth interviews conducted in 2019 (32 males and 20 females) in the Bangladesh refugee camps. The first is a narrative analysis of history from the perspectives of Rohingya refugees. The second is a thematic analysis of interviews to identify the most prominent themes of their lived experience in Myanmar before fleeing to Bangladesh. Contemporary narratives are analyzed through two closely related theoretical frameworks: ethnic nationalism, and ethnic conflict. The most recent years are analyzed through moral panic theory to explain how other Burmese civilians readily tolerated, even cheered, mass atrocities against the Rohingya.
Findings from this study indicate that since 2012, the Buddhist nationalism movement normalized oppression, ostracization, and expulsion of the Rohingya to new heights, enabling law enforcement groups to commit abuses before 2016-2017. The movement provoked moral panic among Burmese Buddhists and, most consequentially, Rakhine Buddhist civilians. The movement used mechanisms of moral disengagement in promoting their ideology and as a means of self-exoneration. A collective attitude of existential fear of, and contempt for, the Rohingya presence enabled the military to conduct a brutal campaign of ethnic cleansing, including areas of genocide, with domestic impunity. This study highlights the special significance of the dehumanization of Rohingya by Buddhist nationalists in enabling atrocities and suggests the power of humanization as a potential intervention strategy in moral panic situations that pose a risk for genocide.Ph.D.Includes bibliographical reference
Art at the Edge: Twelve Case Studies of Curatorial Practice on the U.S./Mexico Border
No full textThis book investigates the artistic practices of contemporary artists who have responded to the current sociopolitical environment of the border between the U.S. and Mexico. The highlighted artists, most of whom embrace new media, include: 1. Alejandro Almanza Pereda (b. 1977, Mexico City; resides New York, NY) 2. Marcela Armas (b. 1976, Durango, Mexico; resides Mexico City) 3. Margarita Cabrera (b. 1973 Monterrey, MX; resides El Paso, TX and Houston, TX) 4. Tania Candiani (b. 1974, Mexico City; resides Tijuana and Mexico City) 5. Liz Cohen (b. 1973, Phoenix, AZ; resides Detroit, MI) 6. Adrian Esparza (b. 1970, El Paso, TX; resides El Paso, TX) 7. Enrique Jezik (b. 1961, Cordoba, Argentina; resides Mexico City) 8. Tom Leader Studio (Tom Leader, Sarah Cowles, Alan Smart) 9. Julio Cesar Morales (b. 1966, Tijuana, Mexico; resides San Francisco, CA) 10. Marcos Ramirez ERRE (b. 1961, Tijuana, Mexico; resides Tijuana, MX) 11. SIMPARCH (Steve Badgett b. 1962 Illinois; resides Chicago, IL . Matt Lynch b. 1969 Indiana; resides Cincinnati, OH) Some of these artists are Mexican living in Mexico. Some are Mexican living in the U.S. Others are Mexican American. And yet others are U.S. citizens of European ancestry. All of them have studied and/or resided in the border region. All were born in the 1960s and 1970s but are at varying stages of artistic development and recognition. The link between them is an shared interest in the current climate of the U.S./Mexico border and the conveyance of this territory in visual terms. Subjects include immigration struggles, low rider automobiles, Mexican street vendors, drug-related and domestic violence, water’s scarcity, managed agricultural lands, and the fluidity of cross-border cultural exchange in spite of the intimidation of physical walls. For example, Marcos Ramirez ERRE launched his career with the Toy-an-Horse, a architectural-scale wooden horse with two heads, one looking north and the other south, that he position at the San Ysidro border crossing between San Diego and Tijuana. The border is, in his words, his “zone of action.” In contrast, Tom Leader has created to date only one project about the border during the course of his career as a landscape architect. Divergent levels of investment in and commitment to the subject on the part of the artists creates a book that addresses a multitude of issues and concerns; it is a rich and interesting analysis of many aspects of contemporary art, in addition to probing the border situation. Performance, photography, sculpture, and video will be the focus. The author is a contemporary art curator who has interacted with all of these artists and exhibited artwork by most of them during her nearly 7-year tenure as the director of the Stanlee and Gerald Rubin Center for the Visual Arts at the University of Texas at El Paso, which is situated less than one mile from Juarez, MX. The discussion of each artist will include insights about the museum practice, installation opportunities and challenges, collaborative endeavors and educational outreach that apply to that specific artist’s endeavors. References to previously published accounts of the artists work and to applicable literary and art theory will also be included when appropriate
Study of multi-muon events produced in p (p)over-bar interactions at root s=1.96 TeV
No full textWe report the results of a study of multi-muon events produced at the Fermilab Tevatron collider and acquired with the CDF II detector using a dedicated dimuon trigger. The production cross section and kinematics of events in which both muon candidates are produced inside the beam pipe of radius 1.5 cm are successfully modeled by known processes which include heavy flavor production. In contrast, we are presently unable to fully account for the number and properties of the remaining events, in which at least one muon candidate is produced outside of the beam pipe, in terms of the same understanding of the CDF II detector, trigger, and event reconstruction. © 2010 The Author(s)
Testing models of collaboration among high school science teachers in an electronic environment
No full textTeacher collaboration is one of the strategies for encouraging teaches to work together to achieve their common ends. In a complex modern world, teachers rarely have time to collaborate with each other. E-mail and Internet technology encourages teacher collaboration to emerge with personal interaction. E-mail is rapid, permitting responses within the same day or even a few hours. On the network, teachers can seek advice from teachers on other campuses and around the world, and at the same time, they can build their relationship with other users. In Western Australia, an e-mail network for science curriculum leaders was established in both primary and secondary schools. In 1998, a study showed that 93 heads of science departments in government high schools were connected to this e-mail network, and more than two-thirds of them had their computers connected to the World Wide Web.
This study aims to: firstly, test Fishbough's models of collaboration among high school science teachers in an electronic environment (e-mail and Internet); and secondly, presents a detailed science web site analysis in terms of the potential of these websites to foster collaboration. The investigation is divided into two distinct studies: Study One is a survey of the teachers' perceptions of collaboration via the Internet and Study Two is a detailed science website analysis.
Study One employed both mail questionnaire and face-to-face interview techniques as methods of data collection. The Science Teacher Collaboration via E-mail and Internet Questionnaire was developed and used to collect data on models of collaboration and interaction perspective of collaborative relationships via the Internet of science teachers at the selected schools. The information from quantitative analysis was used to compose the interview schedule. The follow-up interview was conducted with science teachers who agreed to be interviewed at the sample schools.
Study Two adopted a content analysis technique for analysis of data collected from the two kinds of science websites, specific science websites for science teachers and science websites for general audiences from five chosen continents, Australia, Asia, Europe, America and Africa.
The study found that the Consulting model of collaboration is frequently used by science teachers and science web sites from five chosen continents
Improved determination of the sample composition of dimuon events produced in p(p)over-bar collisions at root s=1.96 TeV
No full textWe use a new method to estimate with 5% accuracy the contribution of pion and kaon in-flight-decays to the dimuon data set acquired with the CDF detector. Based on this improved estimate, we show that the total number and the properties of the collected dimuon events are not yet accounted for by ordinary sources of dimuons which also include the contributions, as measured in the data, of heavy flavor, Υ{hooked}, and Drell-Yan production in addition to muons mimicked by hadronic punchthrough. The number of unaccounted events corresponds to (12.8±3.2)% of the bb̄ production. We find that (23±6)% of the unaccounted events contain additional muon candidates. For comparison, this fraction is (6.9±0.4)% for events due to bb̄ production. © 2011 The Author(s)

Prenatal Restraint Stress Generates Two Distinct Behavioral and Neurochemical Profiles in Male and Female Rats
No full textPrenatal Restraint Stress (PRS) in rats is a validated model of early stress resulting in permanent behavioral and neurobiological outcomes. Although sexual dimorphism in the effects of PRS has been hypothesized for more than 30 years, few studies in this long period have directly addressed the issue. Our group has uncovered a pronounced gender difference in the effects of PRS (stress delivered to the mothers 3 times per day during the last 10 days of pregnancy) on anxiety, spatial learning, and a series of neurobiological parameters classically associated with hippocampus-dependent behaviors. Adult male rats subjected to PRS ("PRS rats'') showed increased anxiety-like behavior in the elevated plus maze (EPM), a reduction in the survival of newborn cells in the dentate gyrus, a reduction in the activity of mGlu1/5 metabotropic glutamate receptors in the ventral hippocampus, and an increase in the levels of brain-derived neurotrophic factor (BDNF) and pro-BDNF in the hippocampus. In contrast, female PRS rats displayed reduced anxiety in the EPM, improved learning in the Morris water maze, an increase in the activity of mGlu1/5 receptors in the ventral and dorsal hippocampus, and no changes in hippocampal neurogenesis or BDNF levels. The direction of the changes in neurogenesis, BDNF levels and mGlu receptor function in PRS animals was not consistent with the behavioral changes, suggesting that PRS perturbs the interdependency of these particular parameters and their relation to hippocampus-dependent behavior. Our data suggest that the epigenetic changes in hippocampal neuroplasticity induced by early environmental challenges are critically sex-dependent and that the behavioral outcome may diverge in males and females.

The exploration of the therapeutic potential of THC and other natural and synthetic cannabinoid compounds was paralleled by the discovery of the endocannabinoid system, comprising cannabinoid receptors and their endogenous ligands, which offered exciting new insights into brain function. Besides its well-known involvement in specific brain functions, such as control of movement, memory and emotions, the endocannabinoid system plays an important role in fundamental developmental processes such as cell proliferation, migration and differentiation. For this reason, changes in its activity during stages of high neuronal plasticity, such as the perinatal and the adolescent period, can have long-lasting neurobehavioral consequences. Here, we summarize human and animal studies examining the behavioral and neurobiological effects of in utero and adolescent exposure to cannabis. Since cannabis preparations are widely used and abused by young people, including pregnant women, understanding how cannabinoid compounds affect the developing brain, leading to neurobehavioral alterations or neuropsychiatric disorders later in life, is a serious health issue. In addition, since the endocannabinoid system is emerging as a novel therapeutic target for the treatment of several neuropsychiatric diseases, a detailed investigation of possible adverse effects of cannabinoid compounds on the central nervous system (CNS) of immature individuals is warranted.

Italian Neurological Soc Cognitive and psychosocial features of childhood and juvenile MS NEUROLOGY English Article PEDIATRIC MULTIPLE-SCLEROSIS; IMPAIRMENT; CHILDREN; DYSFUNCTION; DIAGNOSIS; FATIGUE; DISABILITY; IMPACT; SCALE; LIFE Objective: To assess the impact of multiple sclerosis (MS) on cognitive and psychosocial functioning in childhood and juvenile cases. Methods: We used an extensive neuropsychological battery assessing IQ, memory, attention/concentration, executive functions, and language. Fatigue and depression were also measured. An interview on school and daily living activities was obtained from the parents. Performance of cases was compared with that of demographically matched healthy controls. Results: Sixty-three patients and 57 healthy controls were assessed. Five patients (8%) exhibited a particularly low IQ (< 70). Criteria for cognitive impairment (failure on at least three tests) were fulfilled in 19 patients (31%), whereas 32 patients (53%) failed at least two tests. Beyond deficits in memory, complex attention, and executive functions, the profile of deficits was characterized by involvement of linguistic abilities. In the regression analysis, the only significant predictor of cognitive impairment was an IQ score lower than 90 (odds ratio [OR] 18.2,95% CI 4.6-71.7, p < 0.001). Considering the IQ score as a dependent variable, the only significant predictor was represented by younger age at onset (OR 0.7, 95% CI 0.5-0.9, p = 0.009). Depressive symptoms were reported by 6% of the cases, and fatigue was reported by 73% of the cases. MS negatively affected school and everyday activities in 56% of the subjects. Conclusions: In childhood and juvenile cases, multiple sclerosis (MS) is associated with cognitive impairment and low IQ scores, the latter related to younger age at onset. These aspects are of critical importance in helping children and adolescents with MS to manage their difficulties and psychosocial challenges. [Amato, M.

The temperature dependence of the structural relaxation time indicates that the fragility of liquid CKN changes with pressure. In line with recent proposal [Scopigno , Science 302, 849 (2003)], the change on liquid fragility is followed by a proportional change of the nonergodicity factor of the corresponding glass at low temperature.

A reduction paradigm for output regulation INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL English Article output regulation; nonlinear systems; linear systems; non-minimum-phase systems NONLINEAR INTERNAL-MODELS; SEMIGLOBAL STABILIZATION; FEEDBACK STABILIZATION; SYSTEMS; TOOL The goal of this paper is to provide a reduction paradigm for the design of output regulators which can be of interest for nonlinear as well as linear uncertain systems. The main motivation of the work is to provide a systematic design tool to deal with non-minimum-phase uncertain systems for which conventional high-gain stabilization methods are not effective. The contribution of the work is two-fold. First, this work extends a previous reduction paradigm for output regulation of nonlinear systems. Furthermore, in the case of the uncertain controlled dynamics being linear, we show how the proposed framework leads to a number of systematic design tools of interest for non-minimum-phase linear systems affected by severe uncertainties. A numerical control example of a linearized model of an inverted pendulum on a cart is presented. Copyright (c) 2007 John Wiley & Sons, Ltd.

(Rubiaceae) from Sardinia Island were examined and compared with the iridoidic pattern yet known in Galium species. This comparison evidenced theirs endemic characters. In particular, in G.corsicum and in G. glaucophyllum loganic acid was isolated and identified for the first time in Galium genus. In G. schmidii a rare iridoid is present, 10-hydroxy-loganin, whose presence in this genus was evidenced only in G. mollugo and loganin isolated for the first time.

The remarkable relations among PDEs integrable by the inverse spectral transform method, by the method of characteristics and by the Hopf-Cole transformation JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL English Article KADOMTSEV-PETVIASHVILI EQUATION; NONLINEAR EVOLUTION EQUATIONS; DEPENDENT SCHRODINGER-EQUATION; PARTIAL-DIFFERENTIAL EQUATIONS; SCATTERING TRANSFORM; DRESSING METHOD; CAUCHY-PROBLEM; HIERARCHIES; ALGEBRAS; FIELDS We establish deep and remarkable connections among partial differential equations (PDEs) integrable by different methods: the inverse spectral transform method, the method of characteristics and the Hopf-Cole transformation. More concretely, (1) we show that the integrability properties (Lax pair, infinitely-many commuting symmetries, large classes of analytic solutions) of (2+1)-dimensional PDEs integrable by the inverse scattering transform method (S-integrable) can be generated by the integrability properties of the (1+1)-dimensional matrix Burgers hierarchy, integrable by the matrix Hopf-Cole transformation (C-integrable). (2) We show that the integrability properties (i) of S-integrable PDEs in (1+1) dimensions, (ii) of the multidimensional generalizations of the GL(M, C) self-dual Yang-Mills equations and (iii) of the multidimensional Calogero equations can be generated by the integrability properties of a recently introduced multidimensional matrix equation solvable by the method of characteristics. To establish the above links, we consider a block Frobenius matrix reduction of the relevant matrix fields, leading to integrable chains of matrix equations for the blocks of such a Frobenius matrix, followed by a systematic elimination procedure of some of these blocks. The construction of large classes of solutions of the soliton equations from solutions of the matrix Burgers hierarchy turns out to be intimately related to the construction of solutions in Sato theory. (3) Finally, we show that suitable generalizations of the block Frobenius matrix reduction of the matrix Burgers hierarchy generates PDEs exhibiting integrability properties in common with both S- and C-integrable equations.
