Proclaiming the Peacemaker : The Malaysian church as an agent of reconciliation in a multicultural society
With a history of racial violence and in recent years, low-level ethnic tensions, the themes of peaceful coexistence and social harmony are recurring ones in the discourse of Malaysian society. In such a context, we consider the role of the church as a reconciling agent. We begin by setting out a prima facie case for the doctrine of reconciliation. Interacting with the works of various scholars the main contours of reconciliation are traced, underlining it as a central New Testament theme. Recent years have seen the emergence of missiological readings of reconciliation, and a paradigm of mission in which the social implications of reconciliation highlight the importance of the local church as an agent of peace. Insight into the socio-political context of Malaysia is gained from a survey questionnaire which draws our attention to the relative absence of peacemaking initiatives at the local church level. Seven key themes emerge from the survey results, and the seventh - that of identity, is the key theme to be reckoned with if Malaysian churches are to be agents of reconciliation. This thesis argues that a reconciling presence within a divided society like Malaysia necessitates an ethos of peacemaking. This is created and sustained when Christians understand that their identity has been transformed in Jesus Christ. Our aim will be to demonstrate that being an agent of reconciliation is directly linked to our effectiveness in bearing witness to an identity given by Christ. The concluding section draws from the work of Dietrich Bonhoeffer to support the idea that peace is created as a result of the integration of the self and sustained not in isolation but in fellowship with our neighbour
Modelling the Spoon IRS diagnostic diagram
We explore whether our models for starbursts, quiescent star-forming galaxies
and for AGN dust tori are able to model the full range of IRS spectra measured
with Spitzer. The diagnostic plot of 9.7 mu silicate optical depth versus 6.2
mu PAH equivalent width, introduced by Spoon and coworkers in 2007, gives a
good indication of the age and optical depth of a starburst, and of the
contribution of an AGN dust torus. However there is aliasing between age and
optical depth at later times in the evolution of a starburst, and between age
and the presence of an AGN dust torus.
Modeling the full IRS spectra and using broad-band 25-850 mu fluxes can help
to resolve these aliases. The observed spectral energy distributions require
starbursts of a range of ages with initial dust optical depth ranging from
50-200, optically thin dust emission ('cirrus') illuminated by a range of
surface brightnesses of the interstellar radiation field, and AGN dust tori
with a range of viewing angles.Comment: Accepted for publication by MNRAS. 8 pages, 10 figure
ISO observations and models of galaxies with Hidden Broad Line Regions
We present ISO mid-infrared spectrophotometry and far-infrared photometry of
galaxies with Hidden Broad Line Regions (HBLR). We also present radiative
transfer models of their spectral energy distributions which enable us to
separate the contributions from the dusty disc of the AGN and the dusty
starbursts. We find that the combination of tapered discs (discs whose
thickness increases with distance from the central source in the inner part but
stays constant in the outer part) and starbursts provide good fits to the data.
The tapered discs dominate in the mid-infrared part of the spectrum and the
starbursts in the far-infrared. After correcting the AGN luminosity for
anisotropic emission we find that the ratio of the AGN luminosity to the
starburst luminosity, L(AGN)/L(SB), ranges from about unity for IRAS14454-4343
to about 13 for IRAS01475-0740. Our results suggest that the warm IRAS colours
of HBLR are due to the relatively high L(AGN)/L(SB). Our fits are consistent
with the unified model and the idea that the infrared emission of AGN is
dominated by a dusty disc in the mid-infrared and starbursts in the
far-infrared.Comment: A&A accepeted, 8pages 2 Figures, final versio
Interview of Margaret Mary Markmann, Ph.D.
Dr. Markmann was born in 1948 at the Anderson Hospital in Center City, Philadelphia. She was the fourth of eleven children born into a household of her mother, her father and her grandparents. She grew up in Philadelphia and has lived in the area for her entire life only leaving once after she completed nursing school. During her childhood her extended family lived nearby, her grandmother lived down the street and her Aunt and Uncle lived in the opposite direction. Her father was the direct descendent of Irish immigrants who settled in South West Philadelphia and lived in Southwest Philadelphia for the entirety of their lives. The family also had a summer home in Avalon, New Jersey. Dr. Markmann attended school in one of the largest Catholic Parishes in the United States. There were normally ninety students in the classroom. The school was very large and had 3,300 students attending when she was going to the school. Education was very important for Dr. Markmann and her siblings growing up. Both her father and mother made a point to try and send all eleven of them to college or some form of higher education. After she finished high school she took what she believed was the more practical option as compared to her original desire to become a doctor. Dr. Markmann went to nursing school at St. Joseph’s Hospital School of Nursing in Philadelphia Pennsylvania. She graduated in August 1969 and became a registered nurse. Dr. Markmann worked in the field nursing for a large portion if her professional life. Her first experience was as an emergency room nurse, a position that she held for one year before becoming a Clinical instructor at St. Joseph’s Hospital School of Nursing. She went back to school to get her Bachelor of Arts degree which she received in 1998 from La Salle University with a major in History and a minor in English. She received her Master of Arts from Temple University in 2001. Her original intention was to use that degree to teach high school students. However after she had contacted the Arch Diocese she did not hear back from them for four years. During that time she was contacted to teach a few history courses at La Salle University. That was the start of her professional life at La Salle University. She has been teaching at La Salle University as an adjunct professor since 2002. The majority of the courses that Dr. Markmann teaches at La Salle are Global history courses, most notably HIS 151 and HIS 251. She has also worked in the Dean of Arts and Sciences office as a student advisor for five years, non-consecutively. Many of her children have attended La Salle University and her husband is currently on the Board of Trustees at La Salle. She has been a member of the Parents association at La Salle and both she and her husband have set up the Markmann scholarship for students who attended Catholic School
An Empirical Evaluation of the ClubsNSW (Australia) Multi-Venue Self-Exclusion Program
Few empirical studies have evaluated the effectiveness of self-exclusion programs. Research is required to identify factors contributing to decisions to enter and/or breach self-exclusion orders, or to self-excluded gamblers to seek additional treatment. Clinical characteristics of self-excluders remain relatively unknown in addition to factors that differentiate gamblers who do or do not breach. Limitations of current programs are that gamblers can self-exclude from only one or a limited number of venues. The Multi-venue Self-exclusion program, developed and implemented by ClubsNSW (Australia), is a centralised web-based system designed to help problem gamblers self exclude from up to 35 venues at a time. The online system presents gamblers with the choice of registering from within the venue assisted by the club manager or a trained staff member, or to self-exclude offsite through a gambling counsellor. In a retrospective design, the population characteristics, and the motivations and behaviours of a sample of self-excluded gamblers will be described; the implications of the study findings for the management of the Multi-venue Self-exclusion program will be discussed
Anomalous optical surface absorption in nominally pure silicon samples at 1550 nm
The announcement of the direct detection of Gravitational Waves (GW) by the LIGO and Virgo collaboration in February 2016 has removed any uncertainty around the possibility of GW astronomy. It has demonstrated that future detectors with sensitivities ten times greater than the Advanced LIGO detectors would see thousands of events per year. Many proposals for such future interferometric GW detectors assume the use of silicon test masses. Silicon has low mechanical loss at low temperatures, which leads to low displacement noise for a suspended interferometer mirror. In addition to the low mechanical loss, it is a requirement that the test masses have a low optical loss. Measurements at 1550 nm have indicated that material with a low enough bulk absorption is available; however there have been suggestions that this low absorption material has a surface absorption of > 100 ppm which could preclude its use in future cryogenic detectors. We show in this paper that this surface loss is not intrinsic but is likely to be a result of particular polishing techniques and can be removed or avoided by the correct polishing procedure. This is an important step towards high gravitational wave detection rates in silicon based instruments
Hybridisation:A ‘double-edged sword’ for neotropical plant diversity
Hybridization can facilitate both evolutionary diversification and extinction and has had a critical role in plant evolution, with c. 25% of species known to hybridize in some temperate floras. However, in the species-rich Neotropical flora, the role of hybridization in the evolution of diversity remains unclear. Our review examines studies of hybridization in seed plants from across the Neotropics and explores its outcomes on Neotropical plant evolution. We review studies on a per-biome basis and a spectrum of evolutionary outcomes from hybridization are evident across Neotropical biomes and taxa. These range from short-term impacts, such as the broadening of ecological amplitude in hybrid progeny with transgressive phenotypes and genetic swamping, through to long term impacts, such as the generation of new lineages. Among these studies certain themes emerge, such as the pervasive hybridization among species-rich plant radiations from the Andean páramos, suggesting a role for hybridization in rapid diversification events. Finally, we highlight that hybridization is relatively understudied in the Neotropical flora, despite its remarkable species richness. The advent of genomic techniques can facilitate the study of hybridization and its effects in understudied biomes and plant groups. The increasing availability of genomic resources will eventually allow comparisons between tropical and temperate floras and therefore shed light on the evolutionary impacts of hybridization across the latitudinal biodiversity gradient

Usage and distribution for commercial purposes as well as any dis-tribution of modified material requires written permission.Background: Urology is a rapidly evolving specialty, although wide variations exist between training programs in different countries. We aimed to compare the status of urology training in 5 English-speaking countries. Materials and Methods: Features compared include the training pathway structure, training requirements, competition levels and the process of moving country for international medical graduates. Results: Length of training varied considerably across countries, ranging from 5 years in the USA and Canada, to 7 years in Australia and New Zealand and 9 years in the UK. Ease of entering urology training for international medical graduates also varies, with the UK relatively easier compared to other countries. All countries encourage participation in research during training as well as completion of non-urology and urology specific surgical examinations. Conclusion: Following the Royal College of Surgeons Improving Surgical Training report, it is vital that the UK incorporates optimal elements of international programs in order to provide the best standards for trainees and world-class care in urology.Peer reviewe
Constraining the Cosmological Constant from Large-Scale Redshift-Space Clustering
We show how the cosmological constant can be estimated from redshift surveys
at different redshifts, using maximum-likelihood techniques. The apparent
redshift-space clustering on large scales (\simgt 20 \himpc) are affected in
the radial direction by infall, and curvature influences the apparent
correlations in the transverse direction. The relative strengths of the two
effects will strongly vary with redshift. Using a simple idealized survey
geometry, we compute the smoothed correlation matrix of the redshift-space
correlation function, and the Fisher matrix for \omm and \oml. These
represent the best possible measurement of these parameters given the geometry.
We find that the likelihood contours are turning, according to the behavior of
the angular-diameter distance relation. The clustering measures from redshift
surveys at intermediate-to-high redshifts can provide a surprisingly tight
constraint on \oml. We also estimate confidence contours for real survey
geometries, using the SDSS LRG and QSO surveys as specific examples. We believe
that this method will become a practical tool to constrain the nature of the
dark energy.Comment: 10 pages, 3 figures, submitted to ApJ Letter
A 610-MHz survey of the ELAIS-N1 field with the Giant Metrewave Radio Telescope - Observations, data analysis and source catalogue
Observations of the ELAIS-N1 field taken at 610 MHz with the Giant Metrewave
Radio Telescope are presented. Nineteen pointings were observed, covering a
total area of 9 square degrees with a resolution of 6" x 5", PA +45 deg. Four
of the pointings were deep observations with an rms of 40 microJy before
primary beam correction, with the remaining fifteen pointings having an rms of
70 microJy. The techniques used for data reduction and production of a
mosaicked image of the region are described, and the final mosaic is presented,
along with a catalogue of 2500 sources detected above 6 sigma. This work
complements the large amount of optical and infrared data already available on
the region. We calculate 610-MHz source counts down to 270 microJy, and find
further evidence for the turnover in differential number counts below 1 mJy,
previously seen at both 610 MHz and 1.4 GHz.Comment: 12 pages, 18 figures, two tables. Table 1 can be found in full via
