Teacher leadership and organisational change: a teacher leader's experience in a P-12 school

[Abstract]: Crowther, Hann & McMaster (2001) reported in School Innovation: Pathway to the Knowledge Society that when teacher leaders engage in collective action with the principal, they can build a school’s capacity to change. This Autoethnographic Case Study builds upon the findings reported by Cuttance (2001). The study uses a qualitative inquiry approach to study a Participatory Action Research (PAR) project. The qualitative study was conducted in a P-12 school context in 2003 and contains two related microstudies. The study investigates how a teacher leader, occupying a formal role in an organisation, can contribute to the organisation’s capacity to change. Conducted by a participant observer, the study occurred within a single context, a P-12 school which contained two separate entities, a Primary School and a Secondary School. In the Secondary School, the self researcher occupied a formal position and performed functional tasks while in the Primary School, she exercised teacher leadership without being formally defined by that role. The task of coordinating an innovation to achieve mandated change was distributed to the self researcher by the principal. The self researcher’s efforts to improve her leadership practices while coordinating the innovation forms the basis of the study. The self researcher employed Participatory Action Research as a means to gather data and engaged in reflexive leadership practices to pursue socially just and moral ways of acting in the social world. The organisational context provided the framework for the analysis of the data and various metaphors were employed to analyse the self researcher’s evolving subjectivities. The stance adopted by the self researcher is informed by critical theory, drawing from postmodern and poststructuralist perspectives, and the research question is answered through a narrative. This study found that teacher leadership underpinned by the principles of inclusion, participation and voluntarism is not sustainable in functionalist organisations. The study found that functionalist organisations are imprinted with the discourses of dominance and privilege and the distribution of functions by principals reproduces dominance and oppresses the emergence of teacher leadership. The study found that teacher leadership is emergent not distributed. The study found that when leadership is shared, parallel leadership practices generate organisational-wide leadership and build the collective’s capacity for change. However, the study concludes that the context is important and for teacher leadership to contribute to an organisation’s capacity to change, the organisation itself has to be reimaged

Regional biomechanical and histological characterisation of the passive porcine urinary bladder: Implications for augmentation and tissue engineering strategies

The aim of this study was to identify and quantify potential regional and directional variations in the quasistatic uniaxial mechanical properties of the passive urinary bladder wall. Overall, the lower body and trigone regions demonstrated the highest degree of directional anisotropy, whereas the ventral region demonstrated the least directional anisotropy. Significant regional anisotropy was found only along the apex-to-base direction. The dorsal and ventral regions demonstrated a significantly increased distensibility along the apex-to-base direction compared to the other bladder regions, whereas the trigone and lower body regions demonstrated the least distensibility. The trigone, lower body and lateral regions also demonstrated the highest tensile Strength both at regional and directional levels. The study detected significant regional and directional anisotropy in the mechanical properties of the bladder and correlated this anisotropy to the distended and non-distended tissue histioarchitecture and whole organ mechanics. By elucidating the inhomogeneous nature of the bladder, the results from this study will aid the regional differentiation of bladder treatments in terms of partial bladder replacement with suitable natural or synthetic biomaterials, as well as the development of more realistic constitutive models of bladder wall biomechanics and improved computational simulations to predict deformations in the natural and augmented bladder.

Assessment of Rigour in Published Nursing Intervention Studies that Use Observational Methods

Unstructured observation involving “going into the field” to describe and analyze what is seen and heard, may be an underutilized method in nursing research. The role of the observer, the nature of the observations, data sources, systematic recording and analysis of observations, appropriate analysis of the data, and corroboration of findings are important considerations when ensuring rigour in observational methods. However, the description of observational techniques and methods provided in published accounts of qualitative research is sparse, and it is therefore difficult to evaluate the truthfulness, credibility, and trustworthiness of many research studies. Observational methods can address discrepancies between what people say and what they actually do, and they can capture the context in which nurses practice. Little is known about the oral hygiene care practices of nurses caring for hospitalized older adults with longer lengths of stay, despite the link between poor oral hygiene and systemic illness. To date, the oral hygiene care provided by nurses has not been directly observed, nor have unstructured observational techniques been used to observe any caregivers providing such interventions. In the absence of studies related to oral hygiene care, an integrative review of the literature has been undertaken to critically analyze how rigour was ensured in qualitative or mixed - methods studies in which observational methods were used to study nurses as they provided other types of basic nursing interventions. Whittemore and Knafl’s revised integrative review method was utilized, and criteria that would indicate rigour in a study were gleaned from the literature to create a framework for analysis

The microbiome of urban waters

More than 50% of the world’s population lives in urban centers. As collection basins for landscape activity, urban waters are an interface between human activity and the natural environment. The microbiome of urban waters could provide insight into the impacts of pollution, the presence of human health risks, or the potential for long-term consequences for these ecosystems and the people who depend upon them. An integral part of the urban water cycle is sewer infrastructure. Thousands of miles of pipes line cities as part of wastewater and stormwater systems. As stormwater and sewage are released into natural waterways, traces of human and animal microbiomes reflect the sources and magnitude of fecal pollution and indicate the presence of pollutants, such as nutrients, pathogens, and chemicals. Non-fecal organisms are also released as part of these systems. Runoff from impervious surfaces delivers microbes from soils, plants and the built environment to stormwater systems. Further, urban sewer infrastructure contains its own unique microbial community seemingly adapted to this relatively new artificial habitat. High microbial densities are conveyed via pipes to waterways, and these organisms can be found as an urban microbial signature imprinted on the natural community of rivers and urban coastal waters. The potential consequences of mass releases of non-indigenous microorganisms into natural waters include creation of reservoirs for emerging human pathogens, altered nutrient flows into aquatic food webs, and increased genetic exchange between two distinct gene pools. This review highlights the recent characterization of the microbiome of urban sewer and stormwater infrastructure and its connection to and potential impact upon freshwater systems.

Diversity of Estrogen Degrading Microorganisms in Las Vegas Wash and Lake Mead, Nevada, USA

Endocrine disrupting chemicals (EDCs) are a subject of intense research as more studies reveal their persistence in the environment and detrimental effects on wildlife. Steroid hormones, including the natural and synthetic estrogens estrone (E1), 17-beta-estradiol (E2) and 17- alpha-ethinyl estradiol (EE2), are among the most bioactive and have been detected at low concentrations in waterways downstream from wastewater treatment plants. Las Vegas Wash, a stream flowing into Lake Mead and fed primarily by treated wastewater, provides a unique experimental system in which to study the role microorganisms play in the fate and dispersal of these compounds in surface waters

From Grain to Glass to Covid 19

The case examines the business operations of Midwest Whiskey, MWW, focusing on the downstream supply chain. This includes examining the risks, efficiencies, and modes of distribution for all of the MWW products, before and during the COVID-19 Pandemic. Questions of interest include: Considering the downstream supply chain for MWW, where would you suggest Casey invest in the B2B and B2C Channels? Would your answer change had the pandemic not occurred? What risks does MWW have? Why did you choose each? What capabilities, and subsequent actions, can MWW use to mitigate these? What are positives and negatives to investing in a three way liquor license? What parameters should be taken into consideration in developing a forecasting model

Territorializing spatial data: Controlling land through One Map projects in Indonesia and Myanmar

Once confined to paper, national cartographic projects increasingly play out through spatial data infrastructures such as software programs and smartphones. Across the Global South, foreign donor-funded digital platforms emphasize transparency, accountability and data sharing while echoing colonial projects that consolidated statebased territorial knowledge. This article brings political geography scholarship on state and counter-mapping together with new work on the political ecology of data to highlight a contemporary dimension of territorialization, one in which state actors seek to consolidate and authorize national geospatial information onto digital platforms. We call attention to the role of data infrastructures in contemporary resource control, arguing that territorializing data both extends state territorialization onto digital platforms and, paradoxically, provides new avenues for non-state actors to claim land. Drawing on interviews, document review, and long-term fieldwork, we compare the origins, institutionalization and realization of Indonesia and Myanmar’s ‘One Map’ projects. Both projects aimed to create a government-managed online spatial data platform, building on national mapping and management traditions while responding to new international incentives, such as climate change mitigation in Indonesia and good democratic governance in Myanmar. While both projects encountered technical difficulties and evolved during implementation, different national histories and political trajectories resulted in the embrace and expansion of the program in Indonesia but reluctant participation and eventual crisis in Myanmar. Together, these cases show how spatial data infrastructures can both extend state control over space and offer opportunities for contesting or reimagining land and nation, even as such infrastructures remain embedded in local power relations
