National qualifications in Scotland: A lightning rod for public concern about equity during the pandemic

Scotland, traditionally, has high levels of confidence in teachers. Fairness and justice are key concepts in policy and practice in Scottish education. For more than 100 years, the high-stakes assessment system in Scotland, with the Scottish Higher qualification at its heart, has been crucial to that sense of opportunity and justice. However, in 2019–2020, public confidence in high-stakes assessment in Scotland, as in other United Kingdom countries, was dented. In Scotland, the Covid-19 pandemic meant that schools were closed, teachers provided online learning opportunities for pupils working at home and, for the first time in 130 years, it was not possible to run national examinations. To ensure that learners were not further disadvantaged, alternative approaches to gathering evidence for qualifications were instigated. However, these results were challenged as socially unjust and the results that had been nationally moderated were replaced by results based on locally moderated teachers' professional judgement. As Scotland looks to qualifications beyond Covid-19, trust must be re-built. This article reports on a participative research project that sought to understand public perceptions of standards and fairness across a range of key communities following this experience. Drawing on both qualitative and quantitative data, we analyse factors which affected trust in National Qualifications under the pandemic. The evidence suggests that when considering what matters for qualifications to be trusted, technocratic solutions are likely to be rejected by stakeholders. Understanding and responding to what led to the mistrust of qualifications in Scotland will be crucial to inform its future qualifications system.  相似文献   

Extending the understanding of mobile banking adoption: When UTAUT meets TTF and ITM     

Tiago Oliveira  Miguel Faria  Manoj Abraham Thomas  Aleš Popovič 《International Journal of Information Management》2014

Mobile banking (mBanking) enables customers to carry out their banking tasks via mobile devices. We advance the extant body of knowledge about mBanking adoption by proposing a model for understanding the importance and relationship between the user perception of mBanking, initial trust in mBanking services, and the fit between the technology and mBanking task characteristics. We synergistically combine the strengths of three IS theories – task technology fit (TTF) model, unified theory of acceptance and usage of technology (UTAUT), and initial trust model (ITM). The model was tested in a study conducted in Portugal, one of the European Union (EU) countries with the highest mobile phone adoption. Based on the sample of 194 individuals we applied partial least squares (PLS) to test the conceptual model propose. The path significance levels were estimated using the bootstrapping method (500 resamples). The study found that facilitating conditions and behavioral intentions directly influence mBanking adoption. Initial trust, performance expectancy, technology characteristics, and task technology fit have total effect on behavioral intention. The paper offers valuable insights to decision-makers involved in the implementation and deployment of mBanking services. For researchers, the paper highlights the usefulness of integrating TTF, UTAUT and ITM in the development of a decision support framework to study the adoption of new technologies.  相似文献

A microfluidic device to apply shear stresses to polarizing ciliated airway epithelium using air flow     

Dennis Trieu  Thomas K. Waddell  Alison P. McGuigan 《Biomicrofluidics》2014,8(6)

Organization of airway epithelium determines ciliary beat direction and coordination for proper mucociliary clearance. Fluidic shear stresses have the potential to influence ciliary organization. Here, an in vitro fluidic flow system was developed for inducing long-term airflow shear stresses on airway epithelium with a view to influencing epithelial organization. Our system consists of a fluidic device for cell culture, integrated into a humidified airflow circuit. The fluidic device has a modular design and is made from a combination of polystyrene and adhesive components incorporated into a 6-well filter membrane insert. We demonstrate the system operates within physiologically relevant shear and pressure ranges and estimate the shear stress exerted on the epithelial cell layer as a result of air flow using a computational model. For both the bronchial epithelial cell line BEAS2B and primary human tracheal airway epithelial cells, we demonstrate that cells remain viable within the device when exposed to airflow for 24 h and that normal differentiation and cilia formation occurs. Furthermore, we demonstrate the utility of our device for exploring the impact of exposing cells to airflow: our tool enables quantification of cytoskeletal organization, and is compatible with in situ bead assays to assess the orientation of cilia beating.  相似文献   

Entrepreneurs, Jacks of all trades or Hobos?     

Thomas Åstebro  Peter Thompson 《Research Policy》2011,40(5):637-649

Lazear (2005) suggests that entrepreneurs should be generalists, while those who work for others should be specialists. Many prospective entrepreneurs will develop varied skills by engaging in a variety of employment activities prior to becoming an entrepreneur, and incomes are higher for those that do so. An alternative view predicts that those with greater taste for variety are more likely to become entrepreneurs. Varied employment prior to becoming an entrepreneur is simply an expression of this taste, and is associated with lower earnings. Data from a survey of 830 independent inventors and 300 individuals from the general population are used to discriminate between these two theories. The results show that inventor-entrepreneurs typically have a more varied labor market experience, and that varied work experience is associated with lower household income.  相似文献   

Recent advances in intergroup contact theory     

Thomas F. Pettigrew  Linda R. Tropp 《Int J Intercult Relat》2011,35(3):271-280

Recent advances in intergroup contact theory and research are reviewed. A meta-analysis with 515 studies and more than 250,000 subjects demonstrates that intergroup contact typically reduces prejudice (mean r = −.21). Allport's original conditions for optimal contact - equal status, common goals, no intergroup competition, and authority sanction - facilitate the effect but are not necessary conditions. There are other positive outcomes of intergroup contact, such as greater trust and forgiveness for past transgressions. These contact effects occur not only for ethnic groups but also for such other groups as homosexuals, the disabled and the mentally ill. Intergroup friendship is especially important. Moreover, these effects typically generalize beyond the immediate outgroup members in the situation to the whole outgroup, other situations, and even to other outgroups not involved in the contact. They also appear to be universal - across nations, genders, and age groups. The major mediators of the effect are basically affective: reduced anxiety and empathy. And even indirect contact reduces prejudice - vicarious contact through the mass media and having a friend who has an outgroup friend. Of course, negative contact occurs - especially when it is non-voluntary and threatening. Criticisms of the theory and policy implications are also discussed.  相似文献   

Classification of trampoline jumps using inertial sensors     

Thomas Helten  Heike Brock  Meinard Müller  Hans-Peter Seidel 《Sports Engineering》2011,14(2-4):155-164

The automatic segmentation and classification of an unknown motion data stream according to given motion categories constitute an important research problem with applications in computer animation, medicine and sports sciences. In this paper, the scenario of trampoline motions is considered, where an athlete performs a routine consisting of sequence of jumps that belong to predefined motion categories such as pike jumps or somersaults. As main contribution, a fully automated approach for capturing, segmenting, and classifying trampoline routines according to these categories is introduced. Since trampoline motions are highly dynamic and spacious, optical motion capturing is problematic. Instead, it is reverted to a small number of inertial sensors attached to the athlete’s body. To cope with measurement noise and performance differences, suitable feature and class representations are introduced that are robust to spatial and temporal variations while capturing the characteristics of each motion category. The experiments show that the approach reliably classifies trampoline jumps across different athletes even in the presence of significant style variations.  相似文献
