Constellations of weathering: Following the meteorological mobilities of Bangla bricks

Using follow-the-thing methods and insights from ethnographic fieldwork, this paper traces the meteorological mobilities entwined within Bangladesh bricks. Following the extended lifecycle of the Bangla brick from sediment to clay, from clay to brick and from brick to sediment, and the role that monsoon weathering plays in these processes, reveals complex entanglements of mobilities and materialities. A more-than-human mobilities perspective highlights the myriad human and nonhuman circulations that constitute the brick, as well as the geological, atmospheric and hydrological dynamics that brickmaking sets in motion. Through the becoming and unbecoming of the brick, the paper explores how the mobile materiality of the monsoon is enmeshed within the building blocks of Bangladesh’s cities and the infrastructures on which they depend and how, in turn, the mobile materiality of the brick influences monsoonal environments. These intra-active entanglements trouble perceived dichotomies between society and meteorological forces and highlight the agentive role of weather systems in social worlds

Bangla Bricks: Making and Unmaking Monsoon Grounds

This photo-essay traces the life course of Bangladesh bricks to explore how the monsoon is enmeshed within built environments. It is based on ethnographic observations of brick making in Bangladesh, a terrain within which the monsoon is deeply implicated. Following the cycle of the brick from sediment to clay, from clay to brick and from brick to sediment reveals entanglements of weather, geology and human energies. The mobile materiality of the monsoon is entwined within the very building blocks of Bangladesh’s cities and the infrastructures on which they depend

A New Low-Mass Eclipsing Binary from SDSS-II

We present observations of a new low-mass double-lined eclipsing binary system discovered using repeat observations of the celestial equator from the Sloan Digital Sky Survey II. Using near-infrared photometry and optical spectroscopy we have measured the properties of this short-period [P=0.407037(14) d] system and its two components. We find the following parameters for the two components: M_1=0.272+/-0.020 M_sun, R_1=0.268+/-0.010 R_sun, M_2=0.240+/-0.022 M_sun, R_2=0.248+/-0.0090 R_sun, T_1=3320+/-130 K, T_2=3300+/-130 K. The masses and radii of the two components of this system agree well with theoretical expectations based on models of low-mass stars, within the admittedly large errors. Future synoptic surveys like Pan-STARRS and LSST will produce a wealth of information about low-mass eclipsing systems and should make it possible, with an increased reliance on follow-up observations, to detect many systems with low-mass and sub-stellar companions. With the large numbers of objects for which these surveys will produce high-quality photometry, we suggest that it becomes possible to identify such systems even with sparse time sampling and a relatively small number of individual observations.Comment: 15 Pages, 9 Figures, 6 Tables.

Examining the Effect of Medical-Surgical Nurse Manager Leadership on Employee Organizational Citizenship

An intriguing question in a hospital is “What makes one medical-surgical nursing unit more desirable to nurses, physicians, and patients than another?” This quantitative, correlational research study identified a moderately positive correlation (r = .35, p = .000 between the leadership and communication behaviors of the nurse manager and the organizational citizenship of the nurses and nursing assistants who worked on the medical-surgical nursing units studied. The social impact of this positive correlation is better patient care outcomes.https://scholarworks.waldenu.edu/archivedposters/1071/thumbnail.jp

ADMINISTRATION SIZE AND ORGANIZATION SIZE: AN EXAMINATION OF THE LAG STRUCTURE

Recent longitudinal studies of the relationship between organization and administrative staff size (Freeman & Hannan, 1975) often to replicate the findings of earlier cross-sectional research (Blau herr, 1971). As a result, many researchers (Kimberly, 1976b) have argued that further longitudinal research is necessary

Who is in the transition gap? Transition from CAMHS to AMHS in the Republic of Ireland

Objective: The ITRACK study explored the process and predictors of transition between Child and Adolescent Mental Health Services (CAMHS) and Adult Mental Health Services (AMHS) in the Republic of Ireland. Method: Following ethical approval, clinicians in each of Ireland's four Health Service Executive (HSE) areas were contacted, informed about the study and invited to participate. Clinicians identified all cases who had reached the transition boundary (i.e. upper age limit for that CAMHS team ) between January and December 2010. Data were collected on clinical and socio-demographic details and factors that informed the decision to refer or not refer to AMHS and case notes were scrutinised to ascertain the extent of information exchanged between services during transition

Successful ageing in an area of deprivation: Part 1—A qualitative exploration of the role of life experiences in good health in old age

Objectives: To determine the life histories and current circumstances of healthy and unhealthy older people who share an ecology marked by relative deprivation and generally poor health. Study design: In-depth interview study with a qualitative analysis. Methods: Matched pairs of healthy and unhealthy ‘agers’ were interviewed face-to-face. Healthy ageing was assessed in terms of hospital morbidity and self-reported health. Study participants consisted of 22 pairs (44 individuals), aged 72–89 years, matched for sex, age and deprivation category, and currently resident in the West of Scotland. All study participants were survivors of the Paisley/Renfrew (MIDSPAN) survey, a longitudinal study commenced in 1972 with continuous recording of morbidity and mortality since. Detailed life histories were obtained which focused on family, residence, employment, leisure and health. This information was supplemented by more focused data on ‘critical incidents’, financial situation and position in social hierarchies. Results: Data provided rich insights into life histories and current circumstances but no differences were found between healthy and unhealthy agers. Conclusions: It is important to understand what differentiates individuals who have lived in circumstances characterized by relative deprivation and poor health, yet have aged healthily. This study collected rich and detailed qualitative data. Yet, no important differences were detected between healthy and unhealthy agers. This is an important negative result as it suggests that the phenomenon of healthy ageing and the factors that promote healthy ageing over a lifetime are so complex that they will require even more detailed studies to disentangle

Multiepoch Radial Velocity Observations of L Dwarfs

We report on the development of a technique for precise radial-velocity measurements of cool stars and brown dwarfs in the near infrared. Our technique is analogous to the Iodine (I2) absorption cell method that has proven so successful in the optical regime. We rely on telluric CH4 absorption features to serve as a wavelength reference, relative to which we measure Doppler shifts of the CO and H2O features in the spectra of our targets. We apply this technique to high-resolution (R~50,000) spectra near 2.3 micron of nine L dwarfs taken with the Phoenix instrument on Gemini-South and demonstrate a typical precision of 300 m/s. We conduct simulations to estimate our expected precision and show our performance is currently limited by the signal-to-noise of our data. We present estimates of the rotational velocities and systemic velocities of our targets. With our current data, we are sensitive to companions with M sin i > 2MJ in orbits with periods less than three days. We identify no companions in our current data set. Future observations with improved signal-to-noise should result in radial-velocity precision of 100 m/s for L dwarfs.Comment: Accepted for publication in ApJ, 24 pages, 7 figure
