“…In contrast to the loosely organized elastic lamina in adults, the aortic type of lamellar structure is found in the pulmonary artery trunk in individuals less than 9 years of age (263). However, in high altitude natives the aortic type of lamellar structure persists in adults (28, 264). Similar organization is observed in yaks and llamas adapted to high altitude (62, 111).…”

The pulmonary vasculature is comprised of three anatomic compartments connected in series: the arterial tree, an extensive capillary bed, and the venular tree. Although in general this vasculature is thin-walled, structure is nonetheless complex. Contributions to structure (and thus potentially to function) from cells other than endothelial and smooth muscle cells as well as those from the extracellular matrix should be considered. This review is multifaceted, bringing together information regarding 1) classification of pulmonary vessels, 2) branching geometry in the pulmonary vascular tree, 3) a quantitative view of structure based on morphometry of the vascular wall, 4) the relationship of nerves, a variety of interstitial cells, matrix proteins, and striated myocytes to smooth muscle and endothelium in the vascular wall, 5) heterogeneity within cell populations and between vascular compartments, 6) homo- and heterotypic cell-cell junctional complexes, and 7) the relation of the pulmonary vasculature to that of airways. These issues for pulmonary vascular structure are compared, when data is available, across species from human to mouse and shrew. Data from studies utilizing vascular casting, light and electron microscopy, as well as models developed from those data, are discussed. Finally, the need for rigorous quantitative approaches to study of vascular structure in lung is highlighted.

“…Not all students had chemistry in high school, nor were they taking the class for the first time. The four participants were representative of the group’s heterogeneity; this diversity enriched the perspectives and insights into the chemistry class and the evolving student population at University A . Importantly, all 27 Chem1 students were Hispanic.…”

“…Student engagement (SE) is a complex term that encompasses three dimensions: behavioral (students’ actions in the classroom), cognitive (mental actions while acquiring knowledge), and emotional (attitudes toward school and their sense of belonging). − Because of its complexity, enhancing SE requires addressing it in a holistic way and defining it clearly and operationally . For this research, Zepke and Leach’s definition was used: SE involves “students’ cognitive investment in, active participation in, and emotional commitment to their learning,” as it captures students’ behavioral, cognitive, and emotional engagement (p 168) …”

Student engagement (SE) is essential for student success; it is also extremely complex. SE combines behavioral, cognitive, and emotional engagement; therefore, it must be looked at holistically. This exploratory case study, with four participants, explored how students' lived experiences affected their educational engagement in an introductory chemistry course at a Hispanic Serving Institution (HSI). Data were collected through multiple sources following the triangulation method, and a constant comparison analysis was followed so that patterns could be uncovered through analysis. Five themes that affect SE emerged: university environment, classroom environment, living environment, mental health, and motivation. Those themes, along with their subthemes, demonstrated the relationships between students' lived experiences and their engagement. These themes, sometimes individually and other times confounded, impacted SE in positive or negative ways, depending on the situation. Some factors that positively affected SE for specific participants negatively affected others. These factors revealed the complexities and intersectionalities of SE and how it must be further explored through a holistic lens.

“…More specifically, it encompasses the random selection 13 and subsequent thematic coding 14 of 40 articles from The New York Times and the Washington Post, written and published between 19 March and 1 May 2003, by 20 embedded and 20 unilateral reporters. The use of the NVivo software has enabled the first cycle coding 15 of these articles into codes which can successively be organized into categories (see Appendixes D and E), and the second cycle coding 16 of these categories into three themes corresponding to topics raised in issue narratives established by the US government to legitimize the Iraq War (see Appendix D).…”

Embedded journalism as a strategic enabler in US contentious foreign policy-making domestic legitimization

This article argues that in controversial conflicts, such as the 2003–2011 Iraq War, the US government can strategically utilize the influence it exhibits over the information the mass media have access to in order for war reporters to be (primarily) exposed to information that legitimizes war, and subsequently shares the latter with national audiences via their coverage of the conflict; so as to facilitate the (potential) generation of domestic public support for war, which has been demonstrated to be particularly crucial in contexts of contentious conflicts. Through the interviewing of eight reporters who worked as embedded or unilateral journalists during the Iraq War, and the thematic coding of 40 embedded and unilateral articles from The New York Times and the Washington Post published during this period, this study finds evidence suggesting that, compared to unilateral reporters, the information embedded journalists had access to during the Iraq War was controlled and limited by the US military, and was particularly oriented toward the legitimization of the conflict. Moreover, that this resulted in embedded journalists’ reporting of the Iraq War being, overall, more justifying of the conflict than unilateral reporters’ coverage. This article therefore contributes to the wider understanding of the ways in which the US government can utilize the leverage it posseses over the material the mass media have access to, in order to legitimize contentious foreign policy-making, and possibly gather (critical) favorable domestic public opinion for the latter.
