Don’t Even Think About It! The Effects of Antineutralization, Informational, and Normative Communication on Information Security Compliance

Organizations use security education, training, and awareness (SETA) programs to counter internal security threats and promote compliance with information security policies. Yet, employees often use neutralization techniques to rationalize noncompliant behavior. We investigated three theory-based communication approaches that can be incorporated into SETA programs to help increase compliance behavior: (1) informational communication designed to explain why policies are important; (2) normative communication designed to explain that other employees would not violate policies; and (3) antineutralization communication designed to inhibit rationalization. We conducted a repeated measures factorial design survey using a survey panel of full-time working adults provided by Qualtrics. Participants received a SETA communication with a combination of one to three persuasion statements (informational influence, normative influence statement, and/or an antineutralization), followed by a scenario description that asked for their intentions to comply with the security policy. We found that both informational (weakly) and antineutralization communication (strongly) decreased violation intentions, but that normative communication had no effect. In scenarios where neutralizations were explicitly suggested to participants, antineutralization communication was the only approach that worked. Our findings suggest that we need more research on SETA techniques that include antineutralization communication to understand how it influences behavior beyond informational and normative communication

Direct observation of normal modes in coupled oscillators

We propose a simple and inexpensive method to directly observe each normal mode of a system of coupled oscillators, as well as to measure its corresponding frequency, without performing Fourier analysis or using expensive apparatus. The method consists of applying a frequency dependent force to the system and using the resonance to excite each mode separately. The frequency of the excited mode is determined by measuring the resonance frequency of the system. We found that the measurednormal mode frequencies of coupled oscillators exhibiting two and three normal modes are in very good agreement with the theoretical estimates. The method is suitable for undergraduate students with an elementary knowledge of differential equations

Environmental Learning as a Unique Context for Science Education

Challenges faced by science and environmental educators in respect to the distinctions and interrelationships between these fields have been many over the past few decades. While some scholars note contradicting epistemologies and purposes in their critique of the nature of an environmental (science) education, this paper considers another perspective: through participatory methods it examines how environmental learning may form a unique and qualitatively different context for science education. The paper also highlights a collaborative inquiry into the practices of environmental learning as it is enacted in formal school curriculums in British Columbia, Canada. Our efforts involved critical document analysis of frameworks and resources from around the world. Focus groups and interviews conducted over a period of 16 months informed a collaborative writing process that included teachers, academics and government officials. The framework produced offers a conceptual view for environmental learning in all settings (including science) while providing several principles of teaching and learning to guide educators in designing activities for varied learning contexts. The framework provides a number of perspectives around which environmentally-focused lessons may be developed and demonstrates that environmental education should included scientific understandings but be broadened to include other forms of knowledge including aesthetic appreciation, social responsibility and the development of an environmental ethic

The Combined Effect of Oseltamivir and Favipiravir on Influenza A Virus Evolution

Influenza virus inflicts a heavy death toll annually and resistance to existing antiviral drugs has generated interest in the development of agents with novel mechanisms of action. Favipiravir is an antiviral drug that acts by increasing the genome-wide mutation rate of influenza A virus (IAV). Potential synergistic benefits of combining oseltamivir and favipiravir have been demonstrated in animal models of influenza, but the population-level effects of combining the drugs are unknown. In order to elucidate the underlying evolutionary processes at play, we performed genome-wide sequencing of IAV experimental populations subjected to serial passaging in vitro under a combined protocol of oseltamivir and favipiravir. We describe the interplay between mutation, selection, and genetic drift that ultimately culminates in population extinction. In particular, selective sweeps around oseltamivir resistance mutations reduce genome-wide variation while deleterious mutations hitchhike to fixation given the increased mutational load generated by favipiravir. This latter effect reduces viral fitness and accelerates extinction compared with IAV populations treated with favipiravir alone, but risks spreading both established and newly emerging mutations, including possible drug resistance mutations, if transmission occurs before the viral populations are eradicated

Avaliação do estado nutricional de agroecossistemas de café orgânico no estado de Minas Gerais.

A produção de café orgânico vem se constituindo uma tendência necessária e irreversível do agronegócio brasileiro. Essa atividade tem-se destacado como uma alternativa de renda para alguns cafeicultores, devido à crescente demanda mundial por alimentos mais saudáveis. Entretanto, grande parte das técnicas propostas pela agricultura orgânica está sendo aplicada empiricamente no cultivo de café, principalmente no Estado de Minas Gerais, maior região produtora de café do Brasil. Levando-se em consideração a baixa fertilidade natural dos solos dessa região cafeeira, bem como a elevada extração de nutrientes pelo cafeeiro, objetivou-se neste trabalho identificar possíveis fatores limitantes para a produção orgânica do cafeeiro, relacionados à fertilidade do solo e ao estado nutricional das plantas. Foram realizadas avaliações da fertilidade do solo e análise das folhas em vinte e uma lavouras orgânicas representativas do Estado de Minas Gerais. As amostras de solo foram analisadas para determinação do pH, acidez potencial e dos teores de P, K, Ca, Mg, S, Al e matéria orgânica. As amostras foliares foram analisadas para determinação dos teores de N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn. Com base nos padrões de interpretação para cafeeiros convencionais propostos pela literatura, estabeleceram-se as freqüências com que os caracteres analisados foram inferiores aos critérios de interpretação da fertilidade do solo e estado nutricional das plantas. A análise dos dados foi realizada por estatística descritiva. Novos trabalhos nessa nova área são necessários, visando a uma melhor interpretação da análise foliar e da fertilidade do solo, quando se trabalha com café orgânico

Observation of the Dynamic Beta Effect at CESR with CLEO

Using the silicon strip detector of the CLEO experiment operating at the Cornell Electron-positron Storage Ring (CESR), we have observed that the horizontal size of the luminous region decreases in the presence of the beam-beam interaction from what is expected without the beam-beam interaction. The dependence on the bunch current agrees with the prediction of the dynamic beta effect. This is the first direct observation of the effect.Comment: 9 page uuencoded postscript file, postscritp file also available through http://w4.lns.cornell.edu/public/CLNS, submitted to Phys. Rev.

Sending Granny to Chiang Mai: debating global outsourcing of care for the elderly

This article ties in with existing discussions on global care chains, family separation and the devaluation of social-reproductive work. We explore the new trend of outsourcing care for the elderly to countries with lower wages. We base our analysis on the debate in the German press and supplement it with insights from ethnographic field observations in two care homes in Thailand. We identify a discourse of abandonment, which shows how outsourcing the care of the elderly unsettles the privilege of sedentarism that is often taken for granted in the Global North. Furthermore, the newspaper articles tend to villainize people who seek care for their loved ones abroad. We argue that both discourses foster a neoliberal rationale of individualized responsibility and obfuscate the deep systemic roots of the care crisis in the Global North. However, by extending the discussion on outsourcing care for the elderly beyond the dominant media discourses, we envisage a rich potential for provoking political debate on the revaluation of care

European guidelines (S3) on diagnosis and management of mucous membrane pemphigoid, initiated by the European Academy of Dermatology and Venereology – Part I

This guideline on mucous membrane pemphigoid (MMP) has been elaborated by the Task Force for Autoimmune Blistering Diseases of the European Academy of Dermatology and Venereology (EADV) with a contribution of physicians from all relevant disciplines and patient organizations. It is a S3 consensus-based guideline encompassing a systematic review of the literature until June 2019 in the MEDLINE and EMBASE databases. This first part covers methodology, the clinical definition of MMP, epidemiology, MMP subtypes, immunopathological characteristics, disease assessment and outcome scores. MMP describes a group of autoimmune skin and mucous membrane blistering diseases, characterized by a chronic course and by predominant involvement of the mucous membranes, such as the oral, ocular, nasal, nasopharyngeal, anogenital, laryngeal and oesophageal mucosa. MMP patients may present with mono- or multisite involvement. Patients’ autoantibodies have been shown to be predominantly directed against BP180 (also called BPAG2, type XVII collagen), BP230, laminin 332 and type VII collagen, components of junctional adhesion complexes promoting epithelial stromal attachment in stratified epithelia. Various disease assessment scores are available, including the Mucous Membrane Pemphigoid Disease Area Index (MMPDAI), the Autoimmune Bullous Skin disorder Intensity Score (ABSIS), the ‘Cicatrising Conjunctivitis Assessment Tool’ and the Oral Disease Severity Score (ODSS). Patient-reported outcome measurements (PROMs), including DLQI, ABQOL and TABQOL, can be used for assessment of quality of life to evaluate the effectiveness of therapeutic interventions and monitor disease course

European Guidelines (S3) on diagnosis and management of mucous membrane pemphigoid, initiated by the European Academy of Dermatology and Venereology – Part II

This guideline has been initiated by the task force Autoimmune Blistering Diseases of the European Academy of Dermatology and Venereology, including physicians from all relevant disciplines and patient organizations. It is a S3 consensus-based guideline that systematically reviewed the literature on mucous membrane pemphigoid (MMP) in the MEDLINE and EMBASE databases until June 2019, with no limitations on language. While the first part of this guideline addressed methodology, as well as epidemiology, terminology, aetiology, clinical presentation and outcome measures in MMP, the second part presents the diagnostics and management of MMP. MMP should be suspected in cases with predominant mucosal lesions. Direct immunofluorescence microscopy to detect tissue-bound IgG, IgA and/or complement C3, combined with serological testing for circulating autoantibodies are recommended. In most patients, serum autoantibodies are present only in low levels and in variable proportions, depending on the clinical sites involved. Circulating autoantibodies are determined by indirect IF assays using tissue substrates, or ELISA using different recombinant forms of the target antigens or immunoblotting using different substrates. The major target antigen in MMP is type XVII collagen (BP180), although in 10–25% of patients laminin 332 is recognized. In 25–30% of MMP patients with anti-laminin 332 reactivity, malignancies have been associated. As first-line treatment of mild/moderate MMP, dapsone, methotrexate or tetracyclines and/or topical corticosteroids are recommended. For severe MMP, dapsone and oral or intravenous cyclophosphamide and/or oral corticosteroids are recommended as first-line regimens. Additional recommendations are given, tailored to treatment of single-site MMP such as oral, ocular, laryngeal, oesophageal and genital MMP, as well as the diagnosis of ocular MMP. Treatment recommendations are limited by the complete lack of high-quality randomized controlled trials
