Indigenous Water Justice In Manitoba Through Engagement In Water Governance

Globally, negative impacts on water resources from land development, pollution, and climate change demand greater attention to more effective water governance. In settler colonial countries such as Canada, these negative impacts alter Indigenous relationships with water, land, and each other, and contribute to water insecurity and water injustice for Indigenous peoples. Greater engagement of Indigenous peoples in water governance, research, management, and planning is arguably one way to address negative impacts on water resources in Indigenous communities, but not all types of engagement are as effective as others. I characterize Indigenous engagement in water governance from three geographic scales. A narrative review of the water governance literature finds that Indigenous engagement in settler-colonial nations is generally lacking in both legislation and practice, perpetuating water injustice for Indigenous people. At a regional scale engagement, I examine the degree to which Indigenous participation occurs in provincial watershed planning in Manitoba. At the community-scale, a case study documents the impacts of historic and contemporary water-related decisions as felt by members of Wuskwi Sipihk First Nation, and their efforts in response. Participant observation and interviews with key informants provides practical insight into the water-related challenges facing the community and others in the province. Globally, multiple mechanisms and pathways to water justice are evident in the review, but their efficacy is highly contingent. In Manitoba, inclusion of Indigenous peoples in watershed planning is uneven, and there is limited evidence that Aboriginal and Treaty rights influence rates or nature of participation. Provincially decisions about water are made across different government departments, and Indigenous rights are unevenly recognized and respected between them. Additionally, existing regulatory processes and institutions, while procedurally fair, are not empowered to recognize or accommodate Aboriginal and Treaty rights. In this way, water governance is de-politicized, and settler and capitalist values are privileged above Indigenous rights and values. More support is needed to enhance Indigenous participation in watershed planning and water governance to attain water justice. Enhanced coordination, alternative institutional arrangements, and greater recognition and respect of Indigenous rights are needed to ensure water justice is attainable by Indigenous communities in Manitoba

Dissipative transformation of non-nucleated dwarf galaxies into nucleated systems

Recent photometric observations by the {\it Hubble Space Telescope (HST)} have revealed the physical properties of stellar galactic nuclei in nucleated dwarf galaxies in the Virgo cluster of galaxies. In order to elucidate the formation processes of nucleated dwarfs, we numerically investigate gas dynamics, star formation, and chemical evolution within the central 1 kpc of gas disks embedded within the galactic stellar components of non-nucleated dwarfs. We find that high density, compact stellar systems can be formed in the central regions of dwarfs as a result of dissipative, repeated merging of massive stellar and gaseous clumps developed from nuclear gaseous spiral arms as a result of local gravitational instability. The central stellar components are found to have stellar masses which are typically $~$5% of their host dwarfs and show very flattened shapes, rotational kinematics, and central velocity dispersions significantly smaller than those of their host dwarfs. We also find that more massive dwarfs can develop more massive, more metal-rich, and higher density stellar systems in their central regions, because star formation and chemical enrichment proceed more efficiently owing to the less dramatic suppression of star formation by supernovae feedback effects in more massive dwarfs. Based on these results, we suggest that gas-rich, non-nucleated dwarfs can be transformed into nucleated ones as a result of dissipative gas dynamics in their central regions. We discuss the origin of the observed correlations between physical properties of stellar galactic nuclei and those of their host galaxies.Comment: 13 pages, 4 figures (1 color), ApJL in pres

Episodic disk accretion in the halo of the 'old' Pre-Main Sequence cluster Eta Chamaeleontis

We present multi-epoch medium-resolution observations of two M4.5 candidate members in the halo of the ~8 Myr Eta Chamaeleontis open cluster. Over six months of observations both stars exhibited variations in their H-alpha line profiles on timescales of days to months, with at least one episode of substantial activity attributable to accretion from a circumstellar disk. We derive an accretion rate ~10^-8.7 Msun/yr for this event, with a rate of ~10^-10.6 Msun/yr in quiescence. Episodic accretion like that observed here means existing surveys of accreting Weak-lined T-Tauri Stars in young clusters are likely incomplete and that gas dissipation timescales calculated from the fraction of accreting objects are underestimates.Comment: 5 pages, 5 figures, 1 table.

Should Pastors Be Available All the Time?

New technology in the form of 24/7 email brings with it increased expectations of begin available, adding to the pressures of work-life balance for employees. Few studies have explored this from the perspective of the Christian pastor, and none within the Seventh-day Adventist Church (SDA) pastoral context. We extend the literature in this area by examining the impact of increased work-email on the work-life balance of SDA local church pastors. Based on responses from Australian SDA local church pastors we find that while pastors find there are some advantages in the flexibility offered by 24/7 work email, it also increases the work pressures on them, impacting on stress and relationships. Effective work-life balance is becoming more difficult for the SDA local church pastor to achieve

What? You Want Me to Write?!

1. Purpose. This paper sets out to report on and evaluate the writing skills of a cohort of accounting and business students. 2. Design/methodology/approach. Students were asked to write an essay describing their learning experience in an introductory accounting class. These essays were then evaluated by experienced teachers of English. 3. Findings. Major weaknesses are that: there is inadequate engagement with the assignment question; there is a paucity of content; writing is diffuse rather than succinct; there are faults with sentence structure and other errors of English expression. 4. Implications. The research brings to the fore the poor writing ability of university accounting students and lays stress on the need to train and more clearly guide the development of these business related skills. Training may require curriculum adjustment to accommodate additional courses of study. 5. Originality. There is a paucity of material related to the writing skills of accounting and business students and this paper attempts to address this gap. 6. Limitations. The cohort studied came from a private Southern California university and the results may not necessarily reflect the writing skills of other university students. The study needs to be replicated in other settings

Anytime Email and Work-Life Balance: An Exploration into the Views of Adventist Schools Australia Employees

Email has extended its reach beyond the traditional workplace into the non-work hours of employees, disrupting the work-life balance. What was once ‘anywhere any time’ has become ‘everywhere all the time’ (Mazmanian, Orlikowski, & Yates, 2013). This study examines the effects of email intrusion on work-life balance from the perspective of a Christian faith-based organisation, which has the additional dimension of espousing a ‘healthy’ balance between work and life. A survey of 500 employees of such an organisation, attracting 208 respondents, found that nearly all employees owned mobile devices that enable them to access work email outside work time,and that they frequently use these devices when not at work to access work emails. The employees perceived that anytime work emails have provided them with increased flexibility, but at the same time generated greater and frequently unrealistic expectations of them, by parents, students and to a minor degree school administrators. These employees also often felt that these anytime emails led them to working longer hours, generated a sense of being overloaded, contrary to the espoused values of a work and life balance and the importance of family. For these employees the solution to the anytime work email intrusion and resulting stress is not some external control. To most of these employees external control would be much too restrictive and teaching was perceived to be and has always been more than just an 8.30am to 3.30pm responsibility

A synthetic sample of short-cadence solar-like oscillators for TESS

NASA's Transiting Exoplanet Survey Satellite (TESS) has begun a two-year survey of most of the sky, which will include lightcurves for thousands of solar-like oscillators sampled at a cadence of two minutes. To prepare for this steady stream of data, we present a mock catalogue of lightcurves, designed to realistically mimic the properties of the TESS sample. In the process, we also present the first public release of the asteroFLAG Artificial Dataset Generator, which simulates lightcurves of solar-like oscillators based on input mode properties. The targets are drawn from a simulation of the Milky Way's populations and are selected in the same way as TESS's true Asteroseismic Target List. The lightcurves are produced by combining stellar models, pulsation calculations and semi-empirical models of solar-like oscillators. We describe the details of the catalogue and provide several examples. We provide pristine lightcurves to which noise can be added easily. This mock catalogue will be valuable in testing asteroseismology pipelines for TESS and our methods can be applied in preparation and planning for other observatories and observing campaigns.Comment: 14 pages, 6 figures, accepted for publication in ApJS. Archives containing the mock catalogue are available at https://doi.org/10.5281/zenodo.1470155 and the pipeline to produce it at https://github.com/warrickball/s4tess .

Abell 1201: a Minor merger at second core passage

We present an analysis of the structures and dynamics of the merging cluster Abell~1201, which has two sloshing cold fronts around a cooling core, and an offset gas core approximately 500kpc northwest of the center. New Chandra and XMM-Newton data reveal a region of enhanced brightness east of the offset core, with breaks in surface brightness along its boundary to the north and east. This is interpreted as a tail of gas stripped from the offset core. Gas in the offset core and the tail is distinguished from other gas at the same distance from the cluster center chiefly by having higher density, hence lower entropy. In addition, the offset core shows marginally lower temperature and metallicity than the surrounding area. The metallicity in the cool core is high and there is an abrupt drop in metallicity across the southern cold front. We interpret the observed properties of the system, including the placement of the cold fronts, the offset core and its tail in terms of a simple merger scenario. The offset core is the remnant of a merging subcluster, which first passed pericenter southeast of the center of the primary cluster and is now close to its second pericenter passage, moving at ~1000 km/s. Sloshing excited by the merger gave rise to the two cold fronts and the disposition of the cold fronts reveals that we view the merger from close to the plane of the orbit of the offset core.Comment: accepted by Ap
