The pedagogical dynamic dramatized in Shaw's Pygmalion, which sets man as a distinct pedagogical authority and woman his subject spawning similarly patterned plays many decades later, has been relatively overlooked in the play's criticism clouded by its predominantly mythical theme. Shaw stages Eliza's pedagogical subordination to Higgins followed by her Nora-esque exit with the declaration, "I'll go and be a teacher." The central premise of this article is that the pioneering modern playwright and feminist's pedagogical rewriting of A Doll's House sets out a historical dialogue between Eliza, a new woman who repositions herself as a teacher renouncing her earlier subordinate pedagogical position that is culturally ascribed to women while threatening to replace her paternal teacher, and her immediate precursors, that is, Victorian women teachers whose professional career was socially "anathematized." Through a historical probe into the social status of Victorian women teachers, the article attempts to align their abortive career with Eliza's new womanly re-appropriation of the profession of teaching. With Pygmalion as the starting point of its query, this article conducts a historical survey on the literary representation of pedagogical women from the mid to late Victorian era to the turn of the century. Reading a wide selection of novels and plays alongside of Pygmalion (1912), such as Jane Eyre (1847), A Doll's House (1879), An Enemy of the People (1882), The Odd Women (1893), and The Importance of Being Earnest (1895), it contextualizes Eliza's resolution to be a teacher within the history of female pedagogy. This historical contextualization of the career choice of one of the earliest new women characters in modern drama helps appraise the historical significance of such choice.

Debates on what is the first skyscraper have been ongoing from time to time since the construction of the Home Insurance Building in Chicago in 1885, which is generally recognized as the first built skyscraper. This paper attempts to verify this assertion through a detailed investigation after identifying the criteria that characterize a skyscraper. By considering and examining several competing buildings for the title of "first skyscraper" in terms of their levels of satisfying these criteria, the paper reconfirms that the Home Insurance Building in Chicago indeed qualifies as the first skyscraper and is the harbinger of future skyscrapers. By introducing technological and associated architectural innovations in this pioneering building, its designer William Le Baron Jenney paved the way for the construction of future skyscrapers. In traditional construction, heavy masonry walls especially at lower levels did not allow large window openings in exterior walls that would permit ample daylight. For the Home Insurance Building, originally built with 10 stories, Jenney created a metal-framed skeletal structure that carried the building's loads, making the building lighter and allowed for large windows permitting ample natural light to the building's interior. The exterior iron columns were encased in relatively small masonry piers mainly for fireproofing, weather-protection and façade aesthetics. Relying on the structural framing on the building's perimeter, the exterior masonry thus turned into a rudimentary "curtain wall" system, heralding the use of curtain wall construction in future skyscrapers. This building's innovative structural system led to what is known as the "Chicago Skeleton," and eventually produced remarkable skyscrapers all over the world.

Purpose: This study aimed to develop a situation-specific theory to explain nurses' experiences of the COVID-19 crisis. Methods: The participants were 16 hospital nurses who experienced the COVID-19 crisis. Data were collected through in-depth individual interviews from September 2, 2020 to January 20, 2021. Transcribed interview contents were analyzed using Corbin and Strauss's grounded theory method. Results: A total of 38 concepts and 13 categories were identified through an open coding process. The core category found was becoming a pioneering nurse who turns crises into opportunities. The causal conditions were the chaos of being exposed defenselessly to an unexpected pandemic, fear caused by a nursing care field reminiscent of a battlefield, and moral distress from failing to protect patients' human dignity. The contextual conditions were feeling like the scapegoat of the hospital organization, increasing uncertainty due to the unpredictable state of COVID-19, and relative deprivation due to inappropriate treatment. The central phenomenon was suffering alone while experiencing the dedication of the COVID-19 hero image. The action/interactional strategy were efforts to find a breakthrough and getting the nurse's mind right, and the intervening conditions were gratitude for those who care for broken hearts and getting used to myself with repetitive work. The Consequences were becoming an independent nurse and frustration with the unchanging reality. Conclusion: This study provides the foundation for the nurse's situation-specific theory of the COVID-19 crisis by defining the crisis perceived by nurses who cared for COVID-19 patients and suggesting types of coping with the crisis.

Radon is a naturally occurring carcinogenic agent, poses a serious health hazard when inhaled or ingested in significant amounts. The water of the Padma river will be used as a tertiary coolant for the soon-to-be-commissioned 'Rooppur Nuclear Power Plant'. Hence, it is important to assess the radiological status of the river prior to the commission of this power plant. Therefore, for the first time, 25 samples of water were collected from various locations of the Padma River and analyzed for radon concentration using the RAD H₂O (DURRIDGE) radon monitoring device. The radon concentrations were found in the range from 0.077 ± 0.036 to 0.494 ± 0.211 Bq/L with a mean of 0.250 ± 0.093 Bq/L. All the concentrations were found to be below the recommended limits of WHO (100 Bq/L) and USEPA (11.1 Bq/L). The mean annual effective dose due to the radon exposure via inhalation and ingestion pathways were 0.638 µSv/y and 0.629 µSv/y, respectively, which were all well below the annual effective dose recommended by WHO (0.1 mSv/y). Since Bangladesh lacks a national safety limit of radon in water, this pioneering study provides baseline data on radon levels for the environment around Rooppur Nuclear Power Plant.
