Documenting Privacy Dark Patterns: How Social Networking Sites Influence Users’ Privacy Choices

Dark patterns are user interface (UI) design strategies intended to influence users to make choices or perform actions that benefit online services. This study examines the dark patterns employed by social networking sites (SNSs) to influence users to make privacy-invasive choices. We documented the privacy dark patterns encountered in attempts to register an account, configure account settings, and log in and out for five SNSs popular among American teenagers (Discord, Twitter, Instagram, TikTok, and Snapchat). Based on our observations, we present a typology consisting of three major types of privacy dark patterns (Obstruction, Obfuscation, and Pressure) and 10 subtypes. These strategies undermine the ability of users to make conscious, informed decisions about the management of their personal data – and as prolific users of social media who sometimes demonstrate a lack of knowledge and concern about online privacy, teens are especially vulnerable. We outline the implications of our findings for teens’ privacy on social media and the development of dark pattern countermeasures

El trabajo colaborativo en la expresión escrita de textos descriptivos en inglés en los estudiantes de un instituto superior de Lima-2018

La presente investigación se desarrolló con el fin de estudiar la influencia del trabajo colaborativo en la expresión escrita de textos descriptivos en inglés en los estudiantes del curso de Idioma extranjero I de una institución superior de Lima durante el semestre 2018-2. Se seleccionó un grupo experimental de 18 estudiantes. El tipo de investigación aplicado fue de diseño pre experimental. Para recoger los datos de la variable dependiente se elaboró y aplicó una prueba escrita de conocimientos de inglés al grupo experimental (pre y post test). Como experiencia se desarrollaron 14 sesiones según los conceptos del sílabo, pero con énfasis en el trabajo colaborativo para la producción de textos descriptivos en inglés en los estudiantes del grupo experimental. Para la comprobación de hipótesis se utilizó la prueba T de Student, la cual arrojó como resultado un alto nivel de paridad en el grupo experimental, con 26.6389 en el pre test y 25.9167 en el post test, esto indica que no se cumple una significancia bilateral. Sin embargo, dentro del grupo experimental hubo una parte que mostró una mejora en su rendimiento y presentó una alta significatividad con un puntaje de 22.285 en el pre test y un puntaje de 30.00 en el post test, lo cual significa una influencia importante del trabajo colaborativo en la producción de textos descriptivos en inglés en estos estudiantes

Trapped imbalanced fermionic superfluids in one dimension: A variational approach

We propose and analyze a variational wave function for a population-imbalanced one-dimensional Fermi gas that allows for Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) type pairing correlations among the two fermion species, while also accounting for the harmonic confining potential. In the strongly interacting regime, we find large spatial oscillations of the order parameter, indicative of an FFLO state. The obtained density profiles versus imbalance are consistent with recent experimental results as well as with theoretical calculations based on combining Bethe ansatz with the local density approximation. Our variational wave function displays no signature of the FFLO state in the densities of the two fermion species. Nonetheless, the oscillations of the order parameter appear in density-density correlations, both in situ and after free expansion. Furthermore, above a critical polarization, the value of which depends on the interaction, we find the unpaired Fermi-gas state to be energetically more favorable

Evaluating remote facilitation intensity for multi-national translation of nurse-initiated stroke protocols (QASC Australasia): a protocol for a cluster randomised controlled trial

Economic evaluation; Process evaluation; StrokeAvaluació econòmica; Avaluació de processos; IctusEvaluación económica; Evaluación de procesos; IctusBackground Facilitated implementation of nurse-initiated protocols to manage fever, hyperglycaemia (sugar) and swallowing difficulties (FeSS Protocols) in 19 Australian stroke units resulted in reduced death and dependency for stroke patients. However, a significant gap remains in translating this evidence-based care bundle protocol into standard practice in Australia and New Zealand. Facilitation is a key component for increasing implementation. However, its contribution to evidence translation initiatives requires further investigation. We aim to evaluate two levels of intensity of external remote facilitation as part of a multifaceted intervention to improve FeSS Protocol uptake and quality of care for patients with stroke in Australian and New Zealand acute care hospitals. Methods A three-arm cluster randomised controlled trial with a process evaluation and economic evaluation. Australian and New Zealand hospitals with a stroke unit or service will be recruited and randomised in blocks of five to one of the three study arms—high- or low-intensity external remote facilitation or a no facilitation control group—in a 2:2:1 ratio. The multicomponent implementation strategy will incorporate implementation science frameworks (Theoretical Domains Framework, Capability, Opportunity, Motivation – Behaviour Model and the Consolidated Framework for Implementation Research) and include an online education package, audit and feedback reports, local clinical champions, barrier and enabler assessments, action plans, reminders and external remote facilitation. The primary outcome is implementation effectiveness using a composite measure comprising six monitoring and treatment elements of the FeSS Protocols. Secondary outcome measures are as follows: composite outcome of adherence to each of the combined monitoring and treatment elements for (i) fever (n=5); (ii) hyperglycaemia (n=6); and (iii) swallowing protocols (n=7); adherence to the individual elements that make up each of these protocols; comparison for composite outcomes between (i) metropolitan and rural/remote hospitals; and (ii) stroke units and stroke services. A process evaluation will examine contextual factors influencing intervention uptake. An economic evaluation will describe cost differences relative to each intervention and study outcomes. Discussion We will generate new evidence on the most effective facilitation intensity to support implementation of nurse-initiated stroke protocols nationwide, reducing geographical barriers for those in rural and remote areas.This study is funded by a National Health and Medical Research Council Investigator Grant (Grant ID: APP1196352) awarded to SM.

Phyto-oestrogens affect fertilisation and embryo development in vitro in sheep

Phyto-oestrogens such as isoflavones are natural compounds that can profoundly affect reproductive function. In the present study, we tested whether including isoflavone compounds (genistein, biochanin A, formononetin) in the maturation medium would affect the outcomes for ovine oocytes in vitro. Each isoflavone compound was evaluated at five concentrations (0, 2.5, 5, 10, 25µgmL-1) and the entire protocol was repeated four times. Cumulus-oocyte complexes were randomly allocated to the treatments, then fertilised and cultured in vitro. Compared with control (0µgmL-1), the lower concentrations of isoflavone (2.5, 5 and 10µgmL-1) had no detectable effect on the rates of cleavage or embryo development, or on embryo total cell counts (TCC). However, the highest concentration (25µgmL-1) of all three isoflavones exerted a variety of effects (P<0.05): genistein decreased cleavage rate, blastocyst rate and blastocyst efficiency (blastocysts produced per 100 oocytes); biochanin A decreased cleavage rate and blastocyst efficiency; and formononetin decreased blastocyst rate and blastocyst efficiency. Biochanin A (25µgmL-1) reduced embryo TCC specifically at the hatched blastocyst stage (P<0.05). We conclude that the presence of isoflavones at 25µgmL-1 during IVM decreases the cleavage rate and inhibits blastocyst hatching

Comparing physiological responses to hot and cold stress in a cnidarian–algal holobiont, \u3ci\u3eExaiptasia diaphana\u3c/i\u3e

Coral bleaching—the breakdown of the cnidarian–algal symbiosis—is a major cause of reef decline. The sea anemone Exaiptasia diaphana, commonly known as Aiptasia, is used as a model to study cnidarian-algal symbiosis in laboratory settings. Aiptasia can live with or without symbionts, which allows scientists to study the host combined and separate from the influence of the symbionts. Scientists are able to trigger the breakdown of the symbiosis using heat or cold stress. Cold stress is more commonly used to render aposymbiotic Aiptasia because it seems to be less harmful to the host than bleaching under heat stress. Is cold really less harmful than heat stress? We compared hot and cold stress responses to different stress regiments: a gradual temperature change, a gradual temperature change followed by a sudden temperature change, and a sudden temperature change from ambient conditions. We explored multiple physiological responses of the anemones to determine their level of stress response. We measured mortality and algal density in the host, as well as carbohydrate in the host and symbiont fractions. We also measured peroxide production in algal cultures exposed to the same treatment regimes. After repeating the experiment twice, we found that anemones had different responses, which emphasizes the necessity for repeated experiments in research conducted with live subjects

The Proceedings of the International Civil Aviation English Association (2019) Conference

Hosted by All Nippon Airways (ANA) in Chiba, Tokyo, Japan, the 2019 International Civil Aviation English Association (ICAEA) annual conference focused on exploring the aviation English training needs of ab-initio pilots and air traffic controllers, as well as aircraft maintenance personnel. Globally, much of the demand for new pilots and air traffic controllers is located in areas of world for which English is not a first or national language. Exploring this resulting need to train non-native English speaking personnel was a primary focus of the 2019 ICAEA conference, including consideration of the language proficiency required for success in initial training, test design and implementation, instructional techniques, and the actual language used by this target population. Further, although the International Civil Aviation Organization (ICAO) Language Proficiency Requirements (LPRs) do not directly apply to maintenance personnel, the widespread use of English in the international aviation maintenance industry necessitates language-training solutions. For the first time, the ICAEA conference included a specific track for presenters to share their knowledge and experience related to training aircraft maintenance personnel which, until now, has been an underrepresented and underdeveloped area of aviation English. The conference featured plenary presentations, Q&A panels, and practical workshops. More than 100 participants from over 35 countries attended ICAEA’s first event in Asia in seven years. Attendees included representatives from airlines, flight training organizations (FTOs), air navigation service providers (ANSPs), civil aviation authorities (CAAs), universities, and training and testing providers from all over the world. These proceedings feature six articles written by seven of the presenters, summarizing their practical experiences and research findings which were shared at the conference. This publication is recommended to anyone interested in aeronautical communication. The accompanying presentation materials, as well as shorter summaries of other presentations and workshops, can be found on Embry-Riddle Aeronautical University’s Scholarly Commons page

How registry data are used to inform activities for stroke care quality improvement across 55 countries : A cross-sectional survey of Registry of Stroke Care Quality (RES-Q) hospitals

Background and purpose The Registry of Stroke Care Quality (RES-Q) is a worldwide quality improvement data platform that captures performance and quality measures, enabling standardized comparisons of hospital care. The aim of this study was to determine if, and how, RES-Q data are used to influence stroke quality improvement and identify the support and educational needs of clinicians using RES-Q data to improve stroke care. Methods A cross-sectional self-administered online survey was administered (October 2021–February 2022). Participants were RES-Q hospital local coordinators responsible for stroke data collection. Descriptive statistics are presented. Results Surveys were sent to 1463 hospitals in 74 countries; responses were received from 358 hospitals in 55 countries (response rate 25%). RES-Q data were used “always” or “often” to: develop quality improvement initiatives (n = 213, 60%); track stroke care quality over time (n = 207, 58%); improve local practice (n = 191, 53%); and benchmark against evidence-based policies, procedures and/or guidelines to identify practice gaps (n = 179, 50%). Formal training in the use of RES-Q tools and data were the most frequent support needs identified by respondents (n = 165, 46%). Over half “strongly agreed” or “agreed” that to support clinical practice change, education is needed on: (i) using data to identify evidence–practice gaps (n = 259, 72%) and change clinical practice (n = 263, 74%), and (ii) quality improvement science and methods (n = 255, 71%). Conclusion RES-Q data are used for monitoring stroke care performance. However, to facilitate their optimal use, effective quality improvement methods are needed. Educating staff in quality improvement science may develop competency and improve use of data in practice
