A typology of U.S. metropolises by rent burden and its major drivers.

Scholarly work on rent burden, a rather scantily discussed topic within the broader realm of declining housing affordability, still lacks a firm theory. This article seeks to address this gap by developing a typology of U.S. metropolises which centers on their rent burden status and serves as an initial step toward theory building. We employ principal component and cluster analyses to identify seven distinct types of metropolises and their potential drivers of rent burden. An examination of these seven types suggests that rent burden has spatial randomness to it, since some metropolises in the seven types do not confine to specific geographies. Metropolises with pronounced specializations in education/medicine, information, and arts, recreation, and entertainment exhibit higher rent burden, whereas older Rust Belt metropolises have lower burden. Interestingly, emerging new-economy metropolises exhibit lower rent burden as well, likely reflecting the benefits of newer housing and a diverse economic base. Finally, rent burden, besides being an outcome of the housing demand/supply mismatch, is also a manifestation of income potentials that are affected in complex ways by local labor markets and regional economic specializations.

Gendered dimensions of educational premium disadvantage in earnings in USA, 2019.

The relationships between gender-based earnings disparity and gendered dimensions of human capital gains and labor market changes are quite complex. Some scholars have argued that gender bias improves the over economy of a country/society. Others, however, have argued otherwise, adding to the narrative that despite an overall positive role of educational/human capital gains by women, the benefits reaped by them is non-linear, often with declining premiums for educational progress. This research investigates gendered earnings disadvantage and (dis)parity across US counties by employing GIS-based maps, descriptive statistics, correlations and regression analyses wherein female earnings and female-versus-male earnings ratios are regressed against select explanatory variables representing educational attainments, gender-based work-status, and their occupational over/under-representation in the labor market. Five-years estimates data (2015-2019) from the NHGIS are used for computing location quotients for major occupation-types by gender and additional statistical analyses. Females with professional, Master's and doctoral degrees have improved earnings, even though gender parity is better for both genders among the less educated. Sadly, gender disparity in earnings is higher when male-versus-female ratio increases for those majoring in science/engineering, science and engineering-related and business degrees. Greater gender parity, however, is noted when more men major in Education-a sub-field largely deemed as feminine. This research calls for focused policy interventions toward encouraging more women in STEM and science/engineering disciplines, along with strategic programs to help attract more women into working full-time-one of the several ways toward bridging the earnings gap.

Urban growth and quality of life: inter-district and intra-district analysis of housing in NCT-Delhi, 2001-2011-2020.

One out of three people in India is urban. In 2011, there were about 53 urban agglomerations larger than 1 million population as against only 35 in 2001. Much of this urban expansion has been occurring in the country's largest metropolises including the National Capital Territory of Delhi which has expanded horizontally and vertically both. This has also added to overall decline in its already dilapidated housing stock and quality of life. Delhi, a historical hub for regional, national, and international commerce, and a place for the socio-political elites, has failed to provide basic life amenities to its average citizens. This research critiques the (un)sustainable elements of Delhi's urbanization and concomitant decline in basic amenities pertaining to quality-of-life by examining the growth and expansion of its urban-built-up areas during 2001-2011-2020 and provides nuanced insights into its 'livability' by examining select quality-of-life attributes. The LANDSAT imageries for 2010 and 2020 are used to measure NDB-Index that assesses its built-up area and change, which are later corroborated with Census household data to examine change in its 'livable' and 'dilapidated' housing structures. Significant sub-regional disparity exists in the availability of good and livable homes, with almost 20-30% of several districts still without drinking water source inside premises. However, significant progress is also noted for basic amenities like lighting, latrine and bathing facilities, and majority of Delhi's built-up area has expanded along newer developments and transportation corridors. This calls for goal-oriented strategic interventions by policymakers to help achieve the SDG-11 on Sustainable Cities.

Rental tenure and rent burden: progress in interdisciplinary scholarship and pathways for geographical research.

Rental housing accommodates more than a billion tenants worldwide, and in recent years, rentership has been increasing in some countries. Given reduced access to homeownership in various locations due to several causes, it is critical to focus on rentership which has received relatively less attention compared to homeownership, especially within the geography scholarship. In this review article, we identify four key themes that have naturally emerged from the close examination of recent interdisciplinary literature on rentership and rental affordability. These include: (1) rental housing financialization; (2) the proliferation of single-family rentals resulting from the U.S. foreclosure crisis; (3) the determinants and consequences of rent burden; and (4) the relationship between rent burden and regional economic specialization. We discuss these themes and propose potential opportunities for the geographic analysis of rent burden, its determinants, and their relationships with regional economic specialization. We posit that the four identified themes have been developing in apparent isolation, thus making scholarship less consistent. Moreover, research on rent burden is disjointed in itself, which makes it difficult to establish a unified narrative and interlinked subthemes within the rent burden literature. Nonetheless, we contextualize the four themes in their application to geography and frame our discussion around the central notion of this article-rent burden.

Intraoperative Comparison and Evaluation of Intrathecal Bupivacaine Combined with Clonidine versus Fentanyl in Children Undergoing Hernia Repair or Genital Surgery: A Prospective, Randomized Controlled Trial.

BACKGROUND: Nowadays, spinal anesthesia is commonly being used in infants and children for infraumblical surgeries. Intrathecal adjuvants such as clonidine and fentanyl are used with local anesthetics for additive effects. AIM: The present study aims to assess and compare the effects of adding clonidine versus fentanyl to bupivacaine intrathecally in terms of propofol consumption, hemodynamic profile, adverse events, and complications intraoperatively in pediatric patients. SETTINGS AND DESIGN: A prospective randomized controlled trial was conducted between June 2016 and October 2018 in pediatric patients aged 3-8 years undergoing hernia repair or genital surgery under spinal anesthesia after approval of the Institutional Ethical Committee (Reference No: SGRR/IEC/04/16). MATERIALS AND METHODS: Patients were randomly divided into two equal sized (n = 42) study groups, while analysis was done in (n = 40) each group. Group 1 (BC) received clonidine 1 µg/kg with 0.5% bupivacaine (heavy) and Group 2 (BF) received fentanyl 0.5 µg/kg with 0.5% bupivacaine (heavy). STATISTICAL ANALYSIS: Quantitative data were expressed in mean and standard deviation. Qualitative data were expressed in proportion and percentages. Independent t-test was applied to compare the means of quantitative data, and Chi-square test was used to compare categorical data. P < 0.05 was considered statistically significant. RESULTS: Patient characteristics regarding age, weight, and surgical time were comparable in the two groups. The maintenance dose and bolus dose of propofol consumed during surgery were less in Group 1 than that in the Group 2 and were found to be statistically insignificant. The values of hemodynamic parameters such as heart rate, systolic blood pressure, and diastolic blood pressure were less in Group 1 and were statistically significant at different time intervals. Sedation scores were comparable in both groups. Intraoperative incidence of bradycardia, systolic hypotension, and diastolic hypotension were high in Group 1, whereas the incidence of desaturation was high in Group 2. Intraoperative complications such as apnea and respiratory obstruction were high in Group 2, but were statistically insignificant. CONCLUSION: We conclude that intrathecal adjuvant fentanyl maintains a better hemodynamic profile in terms of adverse events such as bradycardia, systolic hypotension, and diastolic hypotension. Intrathecal clonidine maintains a better sedation level requiring less propofol for sedation. Complications such as apnea and respiratory obstruction can be attributed more to the deep sedation caused by bolus of propofol rather than the inherent properties of intrathecal adjuvant clonidine or fentanyl.

Computer-Based Auditory Training Programs for Children with Hearing Impairment - A Scoping Review.

Introduction Communication breakdown, a consequence of hearing impairment (HI), is being fought by fitting amplification devices and providing auditory training since the inception of audiology. The advances in both audiology and rehabilitation programs have led to the advent of computer-based auditory training programs (CBATPs). Objective To review the existing literature documenting the evidence-based CBATPs for children with HIs. Since there was only one such article, we also chose to review the commercially available CBATPs for children with HI. The strengths and weaknesses of the existing literature were reviewed in order to improve further researches. Data Synthesis Google Scholar and PubMed databases were searched using various combinations of keywords. The participant, intervention, control, outcome and study design (PICOS) criteria were used for the inclusion of articles. Out of 124 article abstracts reviewed, 5 studies were shortlisted for detailed reading. One among them satisfied all the criteria, and was taken for review. The commercially available programs were chosen based on an extensive search in Google. The reviewed article was well-structured, with appropriate outcomes. The commercially available programs cover many aspects of the auditory training through a wide range of stimuli and activities. Conclusions There is a dire need for extensive research to be performed in the field of CBATPs to establish their efficacy, also to establish them as evidence-based practices.

Experimental Hepatotoxicity Produced by Ethinyl estradiol.

Ethinyl oestradiol (EO) is the most commonly used as a component of oral contraceptive and hormonal replacement therapy (HRT) in women. However, its excessive and prolonged use may cause cytotoxicity, including cancer of many organs. Hence, the present study was performed to produce the experimental hepatotoxicity in female albino rats. EO was administered to different groups of rats, respectively @ 250, 500 and 750 µg/kg body weight, orally, weekly for 16 and 20 weeks. One group of rats was administered with saline alone to serve as control. The rats were sacrificed after their respective experimental periods, and the livers were collected and preserved in 10% buffered formalin. Later on, the histopathological study of liver tissues was done. On the 17(th) week, the hepatic tissues showed severe congestion, focal areas of hemorrhage, extreme vacuolation of cytoplasm, distended sinusoids with dilated central veins. Degeneration and necrosis of hepatocytes as evidenced by increased cytoplasmic granularity, and dissolution of nuclear materials were seen. On the 21(st) weeks, these changes were extremely severe and quite conspicuous. Distinct fibrosis was also noticed. EO caused hepatotoxicity, the extent and severity of which were dose and time dependent, indicating that this drug at higher dose after prolonged duration (500 or 750 µg/kg, orally, weekly for 20 weeks) may cause the standard experimental hepatotoxicity in rats.
