Developing Leadership Dispositions for Preparing Urban School Leaders in Chronically Low-Performing Schools

This study originated as an institutionally sponsored research residency conducted using utilization-focused evaluation (Patton, 2008) to investigate the nature of dispositional changes in candidates pursuing National Louis University’s M.Ed. and Ed.S. degrees leading to educational leadership (EDL) state certification in one large urban school district in a Southern state. The EDL program organized learning objectives intending to develop a specific knowledge base, an operational competency set, and, as this study’s focus, leadership dispositions related to preparing assistant principals and principals to lead effectively in chronically low-performing (CLP) schools. The inquiry cross-analyzed data at the intersection of the graduate program’s disposition-related learning objectives with 13 leadership dispositions identified in The Haberman Educational Foundation Star Urban Administrator Pre-Screener. EDL program faculty administered the pre-screener to EDL program candidates twice, yielding 187 matched pairs in pre-program and post-program administrations. Statistical analyses yielded a significant difference (improvement) in overall Haberman scores at the .01 alpha level, as well as an effect size considered (Cohen, 1969) to be a medium effect size. Faculty triangulated the data with interviews of alumni and faculty with experience in leading CLP schools, who affirmed that focus on leadership dispositions serves an important developmental role in an EDL program. The study appears to validate the measurable presence and dynamic changes in EDL candidate dispositions as an element of a graduate program focused on developing effective leaders of CLP schools

Patterns and Trends in Urban Biodiversity and Landscape Design

Urbanization destroys or modifi es native habitats and creates new ones with its infrastructure. Because of these changes, urban landscapes favor non-native and native species that are generalists. Nevertheless, cities reveal a great variety of habitats and species, and, especially in temperate cities, the diversity of vascular plants and birds can be higher than in the surrounding landscapes. The actual occurrence of a species, however, depends on habitat availability and quality, the spatial arrangements of habitats, species pools, a species’ adaptability and natural history, and site history. In addition, cities are particularly human-made ecological systems. Top- down and bottom-up activities of planners, land managers, and citizens create the urban biodiversity in general and in detail. Plants and animals in cities are the everyday life contact with nature of the most humans on our earth. The intrinsic interplay of social and ecological systems with a city often forms unique biotic assemblages inherent to that city. To support native biodiversity, landscape architects, conservation biologists, and other groups are linking landscape design with ecosystem structure and function to create and restore habitats and reintroduce native species in cities

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
