Teaching and Learning in the Spirit of Friendship

This article discusses how the ideals and practices of friendship can provide an edifying ethic for the interactions and relationships of educators and students in the basic communication course. It examines three facets of friendship in the Western tradition, four dialectical tensions of the educational friendship, a collection of six virtues associated with teaching as friendship, and some limitations of the educational friendship

High frequency diffraction of an electromagnetic plane wave by an imperfectly conducting rectangular cylinder

Copyright @ 2011 IEEEWe shall consider the the problem of determining the scattered far wave field produced when a plane E-polarized wave is incident on an imperfectly conducting rectangular cylinder. By using the the uniform asymptotic solution for the problem of the diffraction of a plane wave by a right-angled impedance wedge, in conjunction with Keller's method, the a high frequency far field solution to the problem is given

Open questions in human lung organoid research

Organoids have become a prominent model system in pulmonary research. The ability to establish organoid cultures directly from patient tissue has expanded the repertoire of physiologically relevant preclinical model systems. In addition to their derivation from adult lung stem/progenitor cells, lung organoids can be derived from fetal tissue or induced pluripotent stem cells to fill a critical gap in modelling pulmonary development in vitro. Recent years have seen important progress in the characterisation and refinement of organoid culture systems. Here, we address several open questions in the field, including how closely organoids recapitulate the tissue of origin, how well organoids recapitulate patient cohorts, and how well organoids capture diversity within a patient. We advocate deeper characterisation of models using single cell technologies, generation of more diverse organoid biobanks and further standardisation of culture media

Mineralogical Transformation and Electrochemical Nature of Magnesium-Rich Primers During Natural Weathering

Magnesium-rich primers (MgRP) have generated great interest as a promising alternative to chromium-based primers for the protection of aluminum substrates but their performance during exterior exposure has not been well documented. This paper focuses on the evaluation of MgRP during natural weathering to gain insight into its mineralogical phase transformation and electrochemical nature. Control studies were conducted on Mg and AA2024-T3 coupons. The results indicate that Mg particles in MgRP transform into a variety of hydroxide, carbonate, and hydroxy carbonates. During natural weathering, CO2 inhibited the dissolution of both Mg and AA2024-T3 as a result of protective carbonate layer formation in the coating

Environmental factors influencing pipe failures

This report details work carried out under NERC grants NE/M008339/1 and NE/NO13026/1 which were collaborations between the British Geological Survey and Yorkshire Water, with an additional knowledge transfer component involving Scottish Water and Dŵr Cymru Welsh Water. The work examines whether models developed using environmental, topographical and geohazard information could complement existing management tools, and increase the understanding as to how pipe networks of different materials interact with their broader environment. This can be seen as a first step in identifying ways in which greater resilience could be built into pipe networks

“POOL: A Social History of Segregation Exhibition” Exploring Social Justice Through the Lens of Water Safety Awareness and Art-based Education

Art exhibitions, with a focus on water safety and drowning prevention, are rarely seen as a medium to address social justice and public health, or water safety awareness and drowning prevention efforts in communities. Globally, data have shown drowning is considered a “neglected public health threat” (World Health Organization, 2021, CDC, 2023). Additionally, reports have shown that across the globe there are demographic groups of people impacted by drowning, historical traumas, and social determinants, also impacting some communities that are at greater risk (WHO 2021, CDC, 2023). Although there are national and international efforts to address the importance of water safety, drowning prevention, and its disproportionate impact on historically marginalized, Black, Indigenous People of Color (BIPOC), and culturally and linguistically diverse (CLD) groups, alternative mediums, such as exhibitions of art, which can portray narratives of groups of people and their relationships with water, should be explored to counter stigma, and correct the narratives of BIPOC’s communal relationships to water, in an effort combat drowning disparities.

Eating Christmas Cookies, Whole-wheat Bread and Frozen Chicken in the Kindergarten: Doing Pedagogy by Other Means

The study presented here explores eating as a pedagogical practice by paying attention to arrangements of things such as Christmas cookies, whole-wheat and white bread, frozen chicken, plates, chairs, tables, and freezers. Through a series of ethnographic research examples from German and Brazilian preschools, it investigates how eating in the kindergarten can be a sensual pleasure, a health risk, an ethnic custom, or a civil right within different local histories. Through specific arrangements of foods and other things, young children are educated to eat with moderation, to change their ethnic dietary habits, or to be "modern citizens". Pedagogy can thus consist of doing public health, doing ethnic identity, or doing citizenship. Eating is an important way of doing pedagogy in early childhood education and care settings. © 2013 Springer Fachmedien Wiesbaden
