Rehabilitation in Nepal
As a low-income country with a significant burden of disease and frequent natural disasters, the need for rehabilitation in Nepal is significant. Rehabilitation services currently available in Nepal are limited, but the government has recently adopted a 10-year action plan to address rehabilitation needs nationwide. Rehabilitation education and training is necessary to provide and retain adequate multidisciplinary rehabilitation providers for current and future needs in Nepal. The implementation of evidence-based recommendations to improve the quality of rehabilitation services and access to rehabilitation is critical to maximize individual and community well-being
The Origins of [CII] Emission in Local Star-forming Galaxies
The [CII] 158um fine-structure line is the brightest emission line observed
in local star-forming galaxies. As a major coolant of the gas-phase
interstellar medium, [CII] balances the heating, including that due to
far-ultraviolet photons, which heat the gas via the photoelectric effect.
However, the origin of [CII] emission remains unclear, because C+ can be found
in multiple phases of the interstellar medium. Here we measure the fractions of
[CII] emission originating in the ionized and neutral gas phases of a sample of
nearby galaxies. We use the [NII] 205um fine-structure line to trace the
ionized medium, thereby eliminating the strong density dependence that exists
in the ratio of [CII]/[NII] 122um. Using the FIR [CII] and [NII] emission
detected by the KINGFISH and Beyond the Peak Herschel programs, we show that
60-80% of [CII] emission originates from neutral gas. We find that the fraction
of [CII] originating in the neutral medium has a weak dependence on dust
temperature and the surface density of star formation, and a stronger
dependence on the gas-phase metallicity. In metal-rich environments, the
relatively cooler ionized gas makes substantially larger contributions to total
[CII] emission than at low abundance, contrary to prior expectations.
Approximate calibrations of this metallicity trend are provided.Comment: 8 pages, accepted for publication in Ap
Recording therapy sessions: What do clients and therapists really think?
Aims: Recording therapy sessions has become part of routine practice amongst trainee psychotherapists. To date most research has focused on the benefits of recording sessions to support clinical supervision. There are few data about the benefits or risks for clients. This study aimed to explore the views of clients who had had their therapy sessions recorded and therapists who had recorded sessions. Design: Five clients and 25 therapists completed a qualitative survey, the results of which were analysed using thematic analysis. Findings: All clients and several therapists reported that the recording devices are soon forgotten. Both therapists and clients reported the benefits of recording as being purely for the therapist with none identified for clients. Conclusions: It was observed that clients perhaps did not always understand how recordings were used, suggesting the need for clearer practice guidance. © 2013 British Association for Counselling and Psychotherapy
Transforming professional learning: educational action research in practice
This article seeks to extend current understandings of educational action research, particularly how teachers’ actions, talk and ongoing relatings can serve as a vehicle for transforming their learning, including under current global conditions of more performative accountability. The research is grounded in Noffke’s (2009) understandings of the nature of the personal, professional and political dimensions that characterize action research. While validating Noffke’s (2009) dimensions, we also argue that specific instances of action research help provide insights into not just how action research might be currently understood, but details about how it has actually transformed teachers’ learning practices. To do so, we draw upon recent theorizing into the nature of educational practice, and an example of action research in one school in Australia. Specifically, and drawing upon Kemmis et al. (2014), we reveal the particular ‘doings’ (actions), ‘sayings’ (talk) and ‘relatings’ (relationships) that characterize specific instances of teachers’ learning during part of an action research cycle in this school, under current policy conditions. By indicating how this learning came about, we reveal how the personal, professional and political dimensions (Noffke, 2009) in action research settings are enacted, leading to transformed practice through specific doings, sayings and relatings under current conditions

The emission by dust and stars of nearby galaxies in the Herschel KINGFISH survey
Using new far-infrared imaging from the Herschel Space Observatory with ancillary data from ultraviolet (UV) to submillimeter wavelengths, we estimate the total emission from dust and stars of 62 nearby galaxies in the KINGFISH survey in a way that is as empirical and model independent as possible. We collect and exploit these data in order to measure from the spectral energy distributions (SEDs) precisely how much stellar radiation is intercepted and re-radiated by dust, and how this quantity varies with galaxy properties. By including SPIRE data, we are more sensitive to emission from cold dust grains than previous analyses at shorter wavelengths, allowing for more accurate estimates of dust temperatures and masses. The dust/stellar flux ratio, which we measure by integrating the SEDs, has a range of nearly three decades (from 10(-2.2) to 10(0.5)). The inclusion of SPIRE data shows that estimates based on data not reaching these far-IR wavelengths are biased low by 17% on average. We find that the dust/stellar flux ratio varies with morphology and total infrared (IR) luminosity, with dwarf galaxies having faint luminosities, spirals having relatively high dust/stellar ratios and IR luminosities, and some early types having low dust/stellar ratios. We also find that dust/stellar flux ratios are related to gas-phase metallicity ((log(f(dust)/f(*)) over bar) = -0.66 +/- 0.08 and -0.22 +/- 0.12 for metal-poor and intermediate-metallicity galaxies, respectively), while the dust/stellar mass ratios are less so (differing by approximate to 0.2 dex); the more metal-rich galaxies span a much wider range of the flux ratios. In addition, the substantial scatter between dust/stellar flux and dust/stellar mass indicates that the former is a poor proxy of the latter. Comparing the dust/stellar flux ratios and dust temperatures, we also show that early types tend to have slightly warmer temperatures (by up to 5 K) than spiral galaxies, which may be due to more intense interstellar radiation fields, or possibly to different dust grain compositions. Finally, we show that early types and early-type spirals have a strong correlation between the dust/stellar flux ratio and specific star formation rate, which suggests that the relatively bright far-IR emission of some of these galaxies is due to ongoing (if limited) star formation as well as to the radiation field from older stars, which is heating the dust grains
Star Formation Rates in Resolved Galaxies: Calibrations with Near- and Far-infrared Data for NGC 5055 and NGC 6946
We use the near-infrared Brγ hydrogen recombination line as a reference star formation rate (SFR) indicator to test the validity and establish the calibration of the Herschel/PACS 70 μm emission as a SFR tracer for sub-galactic regions in external galaxies. Brγ offers the double advantage of directly tracing ionizing photons and of being relatively insensitive to the effects of dust attenuation. For our first experiment, we use archival Canada-France-Hawaii Telescope Brγ and Ks images of two nearby galaxies: NGC 5055 and NGC 6946, which are also part of the Herschel program KINGFISH (Key Insights on Nearby Galaxies: a Far-Infrared Survey with Herschel). We use the extinction corrected Brγ emission to derive the SFR(70) calibration for H II regions in these two galaxies. A comparison of the SFR(70) calibrations at different spatial scales, from 200 pc to the size of the whole galaxy, reveals that about 50% of the total 70 μm emission is due to dust heated by stellar populations that are unrelated to the current star formation. We use a simple model to qualitatively relate the increase of the SFR(70) calibration coefficient with decreasing region size to the star formation timescale. We provide a calibration for an unbiased SFR indicator that combines the observed Hα with the 70 μm emission, also for use in H II regions. We briefly analyze the PACS 100 and 160 μm maps and find that longer wavelengths are not as good SFR indicators as 70 μm, in agreement with previous results. We find that the calibrations show about 50% difference between the two galaxies, possibly due to effects of inclination
Analysis of Chimpanzee History Based on Genome Sequence Alignments
Population geneticists often study small numbers of carefully chosen loci, but it has become possible to obtain orders of magnitude for more data from overlaps of genome sequences. Here, we generate tens of millions of base pairs of multiple sequence alignments from combinations of three western chimpanzees, three central chimpanzees, an eastern chimpanzee, a bonobo, a human, an orangutan, and a macaque. Analysis provides a more precise understanding of demographic history than was previously available. We show that bonobos and common chimpanzees were separated ∼1,290,000 years ago, western and other common chimpanzees ∼510,000 years ago, and eastern and central chimpanzees at least 50,000 years ago. We infer that the central chimpanzee population size increased by at least a factor of 4 since its separation from western chimpanzees, while the western chimpanzee effective population size decreased. Surprisingly, in about one percent of the genome, the genetic relationships between humans, chimpanzees, and bonobos appear to be different from the species relationships. We used PCR-based resequencing to confirm 11 regions where chimpanzees and bonobos are not most closely related. Study of such loci should provide information about the period of time 5–7 million years ago when the ancestors of humans separated from those of the chimpanzees
New genetic loci implicated in fasting glucose homeostasis and their impact on type 2 diabetes risk.
Levels of circulating glucose are tightly regulated. To identify new loci influencing glycemic traits, we performed meta-analyses of 21 genome-wide association studies informative for fasting glucose, fasting insulin and indices of beta-cell function (HOMA-B) and insulin resistance (HOMA-IR) in up to 46,186 nondiabetic participants. Follow-up of 25 loci in up to 76,558 additional subjects identified 16 loci associated with fasting glucose and HOMA-B and two loci associated with fasting insulin and HOMA-IR. These include nine loci newly associated with fasting glucose (in or near ADCY5, MADD, ADRA2A, CRY2, FADS1, GLIS3, SLC2A2, PROX1 and C2CD4B) and one influencing fasting insulin and HOMA-IR (near IGF1). We also demonstrated association of ADCY5, PROX1, GCK, GCKR and DGKB-TMEM195 with type 2 diabetes. Within these loci, likely biological candidate genes influence signal transduction, cell proliferation, development, glucose-sensing and circadian regulation. Our results demonstrate that genetic studies of glycemic traits can identify type 2 diabetes risk loci, as well as loci containing gene variants that are associated with a modest elevation in glucose levels but are not associated with overt diabetes
