However, in many institutions there is a lack of training or structures to facilitate these goals. Currently the programme is made of ten teams spread nationwide delivering hands-on science activities to young people and their families. It contributes to addressing national shortfalls in science education by developing a collaborative school-centred outreach initiative that is embedded in the local community. This is achieved by children impersonating scientists and through mentorship by local scientists, facilitating real-life science experiences and one-to-one interactions with science role models. It has followed action research approaches in its methodology to study the most sustainable way of delivering public engagement activities. In parallel, it is also developing teaching and learning solutions by embedding some of its component in HEI student curriculum. The structure and organisation of the programme, its characteristics as well as preliminary findings will be presented at this conference.

When a difference in an outcome eg, pain between exposures eg, treatment groups is observed, one needs to consider whether the effect is truly because of exposure or if alternate explanations are possible. This means evaluating the role of bias and considering the study's statistical precision. In the previous issue, we discussed aspects of statistical testing and precision to explore the question of whether an effect is real or due to chance. Bias relates to systematic sources of error which need to be considered. The internal validity of a study depends greatly on the extent to which biases have been accounted for and necessary steps taken to diminish their impact. Bias may preclude finding a true effect; it may lead to an inaccurate estimate underestimate or overestimate of the true association between exposure and an outcome.

Wael Sh. Basri, Jehan A. Alandejani, Feras M. By using a quantitative research approach and a sample size of students, data were collected about the ICT adoption in universities and the relative performance of students belonging to four Saudi universities. Structure equation modelling was chosen to determine the validity of the research model.

14 Patterns of Biophilic Design

The science learning goals of laboratory experiences include enhancing mastery of science subject matter, developing scientific reasoning abilities, increasing understanding of the complexity and ambiguity of empirical work, developing practical skills, increasing understanding of the nature of science, cultivating interest in science and science learning, and improving teamwork abilities. The research suggests that laboratory experiences will be more likely to achieve these goals if they 1 are designed with clear learning outcomes in mind, 2 are thoughtfully sequenced into the flow of classroom science instruction, 3 integrate learning of science content and process, and 4 incorporate ongoing student reflection and discussion. Computer-based representations and simulations of natural phenomena and large scientific databases are more likely to be effective if they are integrated into a thoughtful sequence of classroom science instruction that also includes laboratory experiences.

Scientific objectivity is a property of various aspects of science. It expresses the idea that scientific claims, methods, results—and scientists themselves—are not, or should not be, influenced by particular perspectives, value judgments, community bias or personal interests, to name a few relevant factors. Objectivity is often considered to be an ideal for scientific inquiry, a good reason for valuing scientific knowledge, and the basis of the authority of science in society. Many central debates in the philosophy of science have, in one way or another, to do with objectivity: confirmation and the problem of induction; theory choice and scientific change; realism; scientific explanation; experimentation; measurement and quantification; statistical evidence; reproducibility; evidence-based science; feminism and values in science. Understanding the role of objectivity in science is therefore integral to a full appreciation of these debates. As this article testifies, the reverse is true too: it is impossible to fully appreciate the notion of scientific objectivity without touching upon many of these debates. The ideal of objectivity has been criticized repeatedly in philosophy of science, questioning both its desirability and its attainability.

Assessing bias: the importance of considering confounding

Biophilic design can reduce stress, enhance creativity and clarity of thought, improve our well-being and expedite healing; as the world population continues to urbanize, these qualities are ever more important. Theorists, research scientists, and design practitioners have been working for decades to define aspects of nature that most impact our satisfaction with the built environment. Biophilia in Context looks at the evolution of biophilic design in architecture and planning and presents a framework for relating the human biological science and nature. Design Considerations explores a sampling of factors e. The Patterns lays out a series of tools for understanding design opportunities, including the roots of the science behind each pattern, then metrics, strategies and considerations for how to use each pattern.

Assessing bias: the importance of considering confounding

This chapter provides an overview of the theory of selective exposure, the idea that people purposefully select messages matching their beliefs.

Selective Exposure Theories

Все данные, свидетельствующие о том, кто чем владел, должны были исчезнуть навсегда. Поскольку для одновременного подрыва устройств была необходима точнейшая координация действий, все эти изделия были связаны между собой телефонными линиями через Интернет. Двое суток встроенные часы устройств обменивались бесконечными потоками зашифрованной синхронизирующейся информации.

Он был бледен и еле дышал. Увидев тело Хейла, Стратмор вздрогнул от ужаса. - О Боже! - воскликнул.  - Что случилось. ГЛАВА 93 Причастие. Халохот сразу же увидел Беккера: нельзя было не заметить пиджак защитного цвета да еще с кровавым пятном на боку.

На этот раз Стратмор позволил себе расхохотаться во весь голос. - Твой сценарий мне понятен. ТРАНСТЕКСТ перегрелся, поэтому откройте двери и отпустите. - Именно так, черт возьми. Я был там, внизу.

Это хорошо защищенный почтовый ящик, и мне лишь случайно удалось на него наткнуться.  - Он выдержал паузу.  - Итак, если Танкадо хотел, чтобы мы обнаружили его почту, зачем ему понадобился секретный адрес. Сьюзан снова задумалась. - Может быть, для того, чтобы вы не заподозрили, что это приманка. Может быть, Танкадо защитил его ровно настолько, чтобы вы на него наткнулись и сочли, что вам очень повезло. Это придает правдоподобность его электронной переписке.

    The social impact of research has usually been analysed through the scientific outcomes produced under the auspices of the research.
