A comparison of timber and forage values within lodgepole pine (Pinus contorta) stands in south-central British Columbia
Creators: name: Spry, Austin Corby
Publisher: name: University of British Columbia
Year: 2011

description: This research compared the influence of pre-commercial thinning (PCT) and fertilization on forage and timber values in three managed lodgepole pine (Pinus contorta Dougl. Var. latifolia Engelm.) forests in the Interior of British Columbia (BC). Cattle (Bos taurus) were grazed in two of the forests. The respective values of treatments were compared using their land expectation value (LEV). Timber values were calculated using the Tree Interpolation Program for Stand Yields (TIPSY) growth and yield model. Cattle use was calculated by relating estimated grazing densities with TIPSY-derived canopy closure estimates for known periods, and establishing a relationship using a linear regression. The value of forage as upland cattle pasture was calculated using a pasture lease rate ($/animal unit month) derived from prior market research in BC, Alberta, and the United States of America. In all study areas the unrelated control was the profit-maximizing silvicultural strategy. In the Summerland study area, no treatment was profitable. In the Kelowna study area, all the unfertilized treatments were profitable. In the Cariboo study area, all treatments were profitable. In all forests, the unfertilized 2000 stems/ha. treatment was the best alternative option, and under the right conditions could be a profit-maximizing investment. The inclusion of forage values in the comparison of investments did not change which treatment was profit-maximizing: treatments affected timber values much more than forage values. This research suggests that under conditions of high site productivity and an assumed social discount rate of 4%, PCT and intensive fertilization can be a profitable management option for interior lodgepole pine stands.

description: Background
In 2010, South Africa’s National Department of Health launched a national primary health care (PHC) initiative to strengthen health promotion, disease prevention, and early disease detection. The strategy, called Re-engineering Primary Health Care (rPHC), aims to provide a preventive and health-promoting community-based PHC model. A key component of rPHC is the use of community-based outreach teams staffed by generalist community health workers (CHWs).

Methods
We conducted focus group discussions and surveys on the knowledge and attitudes of 91 CHWs working on community-based rPHC teams in the King Sabata Dalindyebo (KSD) sub-district of Eastern Cape Province.

Results
The CHWs we studied enjoyed their work and found it meaningful, as they saw themselves as agents of change. They also perceived weaknesses in the implementation of outreach team oversight, and desired field-based training and more supervision in the community.

Conclusions
There is a need to provide CHWs with basic resources like equipment, supplies and transport to improve their acceptability and credibility to the communities they serve.

description: Most people have learned about fear and can articulate their beliefs about it. Yet, this leads to a distortion in part of the whole picture of what fear is about in terms of human history and where we are going--our future unfolding. Dr. Fisher, after 3 decades of research on the topic of fear and fearlessness, offers in this video a way to distinguish and problematize our own habits of understanding fear. He discusses, using critical literacy, his own critical pedagogical approach to the topic and how we can improve our fear management/education on the planet meant for the challenges of the 21st century. Fear, he says, has got ahead of us, we're on catch up with building a better intelligent fear management/education from cradle to grave.. Note: Pierre Bourdieu (Fr. theorist) is what I meant to say.
Making up knowers : objectivity and categories of epistemic subjects
Creators: name: Fellows, Jennifer Jill
Publisher: name: University of British Columbia
Year: 2011

description: The aim of this dissertation is simple: to defend the epistemic concept of objectivity as one that has done and continues to do good ethical and epistemic work for some communities. Because of this good work, I argue, in contrast to philosophers like Richard Rorty and Lorraine Code, that objectivity should not be removed from epistemic discourse—it is a valuable ideal to have. Relying on work from Lorraine Daston and Peter Galison, I will identify objectivity as a concept with a layered and changing history. There are multiple different conceptions of the concept of objectivity currently identified, and more new conceptions being suggested. So, when I claim that objectivity is a valuable ideal to hold, what I mean is that specific conceptions of the concept of objectivity have had ethical and epistemic virtues in their times and places, and there are current suggested conceptions of objectivity that also seem to have ethical and/or epistemic virtues. These virtues are a result of the effect that the role of objectivity as an ideal has on epistemic subjects who adopt it. I will defend objectivity as an ideal, not as an attainable epistemic perspective. I argue that all conceptions of objectivity share a structure that unifies them under the concept of objectivity. All conceptions of objectivity aim at overcoming something identified as problematically subjective (What this thing is will vary in given times and places). This recognition of the relationship between objectivity and subjectivity allows me to give an analysis of how different conceptions of objectivity yield different conceptions of the epistemic subject. Relying on work done by Ian Hacking, I will argue that the ideal of objectivity serves as a mechanism for making up knowers. Self-reflection and self-policing are at the heart of this method by which categories of knowers are created. Using the examples of the U.S. suffrage movement and Marine-Protected Areas, I will demonstrate that the ideal of objectivity obligates self-reflective persons which has been and continues to be both ethically and epistemically beneficial.

description: We present a method to select hot subdwarf stars with A to M-type companions using photometric selection criteria. We cover a wide range in wavelength by combining GALEX ultraviolet data, optical photometry from the SDSS and the Carlsberg Meridian telescope, near-infrared data from 2MASS and UKIDSS. We construct two complimentary samples, one by matching GALEX, CMC and 2MASS, as well as a smaller, but deeper, sample using GALEX, SDSS and UKIDSS. In both cases, a large number of composite subdwarf plus main-sequence star candidates were found. We fit their spectral energy distributions with a composite model in order to estimate the subdwarf and companion star effective temperatures along with the distance to each system. The distribution of subdwarf effective temperature was found to primarily lie in the 20,000 - 30,000 K regime, but we also find cooler subdwarf candidates, making up ~5-10 per cent. The most prevalent companion spectral types were seen to be main-sequence stars between F0 and K0, while subdwarfs with M-type companions appear much rarer. This is clear observational confirmation that a very efficient first stable Roche-lobe overflow channel appears to produce a large number of subdwarfs with F to K-type companions. Our samples thus support the importance of binary evolution for subdwarf formation.

A survey of the irrigation protocols used by dentists in British Columbia, Canada
Creators: name: Abtin, Houman
Publisher: name: University of British Columbia
Year: 2011

description: The goal of endodontic treatment is to prevent and eliminate infection. This is achieved by mechanical and chemical cleaning of the root canal. Chemical cleaning is a process in which irrigants are introduced in the root canal to eradicate bacteria and flush out debris. A study was conducted to assess the type, concentration of sodium hypochlorite (NaOCl), volume, sequence and method of delivery system of different irrigants used by general practitioners (GP) and endodontists (ENDO) in treating teeth with vital (VP) or non-vital pulp (NVP). We hypothesized that there are no significant differences between the groups regarding the method of irrigation in root canal treatment. Methods: 1) A total of 68 samples of bleach were collected from GP offices in Vancouver. Using titration, the concentration of hypochlorite in these bleach samples was calculated. 2) A questionnaire was sent to 150 GP and 42 ENDO registered with the College of Dental Surgeons of British Columbia. Results: The overall response rate to our questionnaire was 70.3%. Irrigants used in treating teeth with VP were NaOCl: ENDO 93.4%, GP 89.9% (p=0.445), EDTA: ENDO 72.9%, GP 35.1% (p<0.001), and RC-Prep™: ENDO 29.7%, GP 67.2% (p< 0.001). Irrigants used in treating teeth with NVP were NaOCl: ENDO 95.7%, GP 94.2% (p= 0.657), EDTA: ENDO 76.2%, GP 36.2% (p< 0.001), and RC-Prep™: ENDO 31.9%, GP 71.9% (p< 0.001). Majority of the ENDO (82.3%) used 5-6% NaOCl whereas 55% of the GP used 3-5% NaOCl. Commonly used irrigation needle by both groups was stainless steel with a tip size of 27G (ENDO 28.0%, GP 36.0%). The irrigation needle was inserted in the pulp chamber ENDO 79.8%, GP 75.2%, the coronal/mid canal: ENDO 79.8%, GP 85.3%, and the apical area ENDO 50.3%, GP 25.2%. Except for EDTA and saline, there were no statistically significant difference between both groups in their choice of the initial, in-between or final irrigant used. Conclusion: The ENDO and GP followed the recommended “best practice” for irrigation regarding the use of antimicrobial agents, such as NaOCl. However, the use of demineralizing agents for removing the smear layer was less frequent, particularly among the GP.

description: Background
Sputum smear-positive tuberculosis (TB) patients have a high risk of transmission and are of great epidemiological and infection control significance. Little is known about the smearpositive populations in high TB burden regions, such as Kazakhstan. The objective of this study is to characterize the smear-positive population in Kazakhstan and identify associated modifiable risk factors.

Methods
Data on incident TB cases’ (identified between April 2012 and March 2014) socio-demographic, risk behavior, and comorbidity characteristics were collected in four regions of Kazakhstan through structured survey and medical record review. We used multivariable logistic regression to determine factors associated with smear positivity.

Results
Of the total sample, 193 (34.3%) of the 562 study participants tested smear-positive. In the final adjusted multivariable logistic regression model, sex (adjusted odds ratio (aOR) = 2.0, 95% CI:1.3–3.1, p < 0.01), incarceration (aOR = 3.6, 95% CI:1.2–11.1, p = 0.03), alcohol dependence (aOR = 2.6, 95% CI:1.2–5.7, p = 0.02), diabetes (aOR = 5.0, 95% CI:2.4–10.7, p < 0.01), and physician access (aOR = 2.7, 95% CI:1.3–5.5p < 0.01) were associated with smear-positivity.

Conclusions
Incarceration, alcohol dependence, diabetes, and physician access are associated with smear positivity among incident TB cases in Kazakhstan. To stem the TB epidemic, screening, treatment and prevention policies should address these factors.
Spherically Averaging Ellipsoidal Galaxy Clusters in X-Ray and Sunyaev-Zel'dovich Studies: II. Biases

description: This is the second of two papers investigating the spherical averaging of ellipsoidal galaxy clusters in the context of X-ray and Sunyaev-Zel'dovich (SZ) observations. In the present study we quantify the orientation-average bias and scatter in observables that result from spherically averaging clusters described by ellipsoidal generalizations of the NFW profile or a nearly scale-free logarithmic potential. Although the mean biases are small and mostly <1%, the flattest cluster models generally have a significant mean bias; i.e., averaging over all orientations does not always eliminate projection biases. Substantial biases can result from different viewing orientations, where the integrated Compton-y parameter (Y_SZ) and the concentration have the largest scatter (as large as sigma ~10% for Y_SZ), and the emission-weighted temperature (T_X) has the smallest (sigma < ~0.5%). The very small scatter for T_X leads to Y_X and M_gas having virtually the same orientation biases. Substantial scatter is expected for individual clusters (up to sigma ~8%) in the correlation between Y_SZ and Y_X in comparison to the small mean bias (sigma < ~1%) applicable to a random sample of clusters of sufficient size. For ellipsoidal NFW models we show that the orientation bias for the total cluster mass attains a minimum near the radius r_2500 so that the spherically averaged mass computed at this radius is always within ~0.5% of the true value for any orientation. Finally, to facilitate the accounting for orientation bias in X-ray and SZ cluster studies, we provide cubic polynomial approximations to the mean orientation bias and 1-sigma scatter for each cluster observable as a function of axial ratio for the ellipsoidal NFW models.

Evaluation of canal instrumentation using GT-Series-X™ versus ProSystem GT™
Creators: name: Tabatabaei, Neda
Publisher: name: University of British Columbia
Year: 2011

description: Preparation of the root canal system is recognized as being one of the most important stages in root canal treatment. A variety of instrumentation techniques have been described for this stage of root canal treatment. Two recently introduced rotary instrument systems are ProSystem GT™ and GT-Series-X™. The aim of this study is to compare the ability of two nickel- titanium rotary file systems, GT-Series-X™, and ProSystem GT™, to maintain the original canal path using a split-mold design (the endodontic cube). The hypothesis is that ProSystem GT™ will create greater canal center displacement in comparison with GT-Series-X™ files due to more chip spaces and fewer cutting flutes in the latter. Methods: Mesial roots of 31 mandibular first and second molar teeth with separate ML and MB canals and curvatures ranging from 15 to 40 degrees were randomly divided into two groups. After access cavity preparation and working length determination, each tooth was embedded in composite resin using the endodontic cube as a mold. 1.5mm tooth-resin complex slices were made using a Buehler ™ slow speed saw. After reassembly of the sections, canals were instrumented with either GT-Series-X™ or ProSystem GT™ to size 30/06. AutoCAD™ software was used to measure root section images of instrumented canals. Data was analyzed using the t-test (p<0.05). Results: The canal center displacement of the ProSystem GT™ was 0.08 ± 0.074mm while for GT-Series-X™ it was 0.064 ± 0.063mm (p<0.05). Conclusion: Both systems tended to move the original canal toward the furcation, but ProSystem GT™ caused significantly greater canal center displacement.

description: Der demographische Wandel ist auch in Deutschland spürbar angekommen. Gekennzeichnet durch eine gewollt immer älter werdene Bevölkerung und die damit verbundene Zunahme chronischer Erkrankungen. Aber auch gekennzeichnet durch eine immer älter werdende Gruppe der Hausärzte. Zukünftig wird die Einbeziehung nichtärztlicher Leistungserbringer in den Versorgungsprozess unumgänglich sein. Durch spezielle Qualifikationsmaßnahmen (VERAH, 1991) können nichtärztliche Praxismitarbeiter bisher ausschließlich ärztliche Aufgaben übernehmen. Die Frage nach den Effekten solcher Qualifikationen auf die Arbeit des Arztes und die Zufriedenheit der Patienten wurden bisher ausschließlich über Fragebogenstudien erörtert. Die vorgelegte Studie bezieht erstmals beobachtbare Daten einer allgemeinmedizinischen Landarztpraxis zur Bewertung der Effekte auf ärztliche Arbeitszeit und Patientenzufriedenheit ein. Hierzu wurden 152 geriatrische Patienten über 3 Monate beobachtet. Alle Tätigkeiten des Arztes und der VERAH wurden erfasst. Die zugehörigen Arbeitszeiten wurden registriert. Zum Vergleich wurde ein Vorbeobachtungszeitraum (12 Monate vor dem Beobachtungszeitraum) herangezogen.
description: The demographic change has also noticeably arrived in Germany. Characterized by an intentionally aging population and the associated increase in chronic diseases. But also characterized by an aging group of family doctors. In the future, the inclusion of non-medical service providers in the care process will be inevitable. Thanks to special qualification measures (VERAH, 1991), non-medical practice staff have so far been able to assume only medical tasks. The question of the effects of such qualifications on the doctor's work and patient satisfaction has so far been discussed exclusively through questionnaire studies. The presented study includes for the first time observable data from a general practitioner's office to evaluate the effects on medical work time and patient satisfaction. 152 geriatric patients were followed for 3 months. All activities of the doctor and the VERAH were recorded. The associated working hours were registered. For comparison, a follow-up period (12 months before the observation period) was used.

description: Im Rahmen dieser Arbeit wurden Präzisionspolymere mit 2,6-Diaminopyridin (DAP), Harnstoff oder TEMPO Funktionalitäten über ADMET Polymerisation hergestellt und anschließend kristallographisch analysiert um den Einfluss verschiedener Zwänge auf die Kristallisation zu untersuchen. Durch WAXS-Analysen konnte für alle Polymere eine lamellare Morphologie nachgewiesen werden. Untersuchungen der gesättigten, methyl-geschützten DAP Polymere weisen auf eine Mischung von orthorhombischen und triklinen Kristallstrukturen hin. Basierend auf DSC Ergebnissen und den Kristalllamellendicken kann davon ausgegangen werden, dass die Defekte zumindest partiell in die kristalline Phase eingeschlossen werden und sich parallel anordnen. Die Änderung der supramolekularen Wechselwirkungen von π-π-Wechselwirkungen zu Wasserstoffbrücken durch Verwendung ungeschützter DAP- oder Harnstoffeinheiten führt zur Änderung der Kristallstruktur von orthorhombisch zu triklin, wobei die Defekte sich leiterartig anordnen.
description: In the scope of this thesis precision polymers bearing 2,6-diaminopyridine (DAP), urea or TEMPO moieties were synthesized via ADMET polymerization and characterized to determine the influence of various internal constraints on the crystallization. The crystallization behavior was examined via WAXS analysis, observing a lamellar morphology for all precision polymers. Investigations on the saturated DAP containing polymers with N-methyl protection group indicate the formation of a mixture of orthorhombic and triclinic crystal structures. Based on DSC results and the calculated lamellar crystal thicknesses a partial incorporation of the functional groups into the crystalline lamella and their parallel arrangement can be assumed. Changing the supramolecular interactions from π-π-stacking to hydrogen bonding by using unprotected DAP or urea moieties leads to the change from the orthorhombic to a triclinic crystal structure, wherein the defects adopt a ladder-like arrangement.

description: Cyclin A1 (Ccna1), a member of the mammalian A type cyclins, is most abundantly expressed in spermatocytes and is essential for spermatogenesis in the mouse. Ccna1- deficient spermatocytes arrest at late meiotic prophase and undergo apoptosis. To further delineate the mechanisms and key factors involved in this process, we have examined changes in expression of genes involved in both intrinsic and extrinsic signaling pathways that trigger apoptosis in the mutant spermatocytes. Our results show that both pathways are involved, and that the factors involved in the intrinsic pathway were expressed earlier than those involved in the extrinsic pathway. We have also begun to identify in vivo Ccna1- interacting proteins, using an unbiased biochemical approach, and identified 14-3-3, a key regulator of apoptosis, as a Ccna1-interacting protein. Expression levels of 14-3-3 proteins remain unchanged between wild type and mutant testes but there were differences in the subcellular distribution. In wild type control, 14-3-3 is detected in both cytosolic and nuclear fractions whereas it is restricted to the cytoplasm in mutant testes. This differential distribution of 14-3-3 may contribute to the induction of apoptosis in Ccna1-deficient spermatocytes. These results provide insight into the apoptotic mechanisms and pathways that are triggered when progression through the meiotic cell cycle is defective in male gametogenesis.

description: We perform simulations for one dimensional continuous-time random walks in two dynamic random environments with fast (independent spin-flips) and slow (simple symmetric exclusion) decay of space-time correlations, respectively. We focus on the asymptotic speeds and the scaling limits of such random walks. We observe different behaviors depending on the dynamics of the underlying random environment and the ratio between the jump rate of the random walk and the one of the environment. We compare our data with well known results for static random environment. We observe that the non-diffusive regime known so far only for the static case can occur in the dynamic setup too. Such anomalous fluctuations give rise to a new phase diagram. Further we discuss possible consequences for more general static and dynamic random environments.

description: Phosphoinositide-dependent kinase 1 (PDK1) plays an important role in integrating the T cell antigen receptor (TCR) and CD28 signals to achieve efficient NF-κB activation. PDK1 is also an important regulator of T cell development, mediating pre-TCR induced proliferation signals. However, the role of PDK1 in B cell antigen receptor (BCR) signaling and B cell development remains largely unknown. In this study we provide genetic evidence supporting the role of PDK1 in B cell survival. We found PDK1 is required for BCR mediated survival in resting B cells, likely through regulation of Foxo activation. PDK1-dependent signaling to NF-κB is not crucial to resting B cell viability. However, PDK1 is necessary for triggering NF-κB during B cell activation and is required for activated B cell survival. Together these studies demonstrate that PDK1 is essential for BCR-induced signal transduction to Foxo and NF-κB and is indispensable for both resting and activated B cell survival.

description: Bilayer silicene has richer physical properties than bilayer graphene due to its buckled structure together with its trigonal symmetric structure. The buckled structure arises from a large ionic radius of silicon, and the trigonal symmetry from a particular way of hopping between two silicenes. It is a topologically trivial insulator since it carries a trivial $\mathbb{Z}_{2}$ topological charge. Nevertheless, its physical properties are more akin to those of a topological insulator than those of a band insulator. Indeed, a bilayer silicene nanoribbon has edge modes which are almost gapless and helical. We may call it a quasi-topological insulator. An important observation is that the band structure is controllable by applying the electric field to a bilayer silicene sheet. We investigate the energy spectrum of bilayer silicene under electric field. Just as monolayer silicene undergoes a phase transition from a topological insulator to a band insulator at a certain electric field, bilayer silicene makes a transition from a quasi-topological insulator to a band insulator beyond a certain critical field. Bilayer silicene is a metal while monolayer silicene is a semimetal at the critical field. Furthermore we find that there are several critical electric fields where the gap closes due to the trigonal warping effect in bilayer silicene.

We show that if positive part of the radial component of velocity satisfies a weighted Serrin condition and in addition angular component satisfies some condition, then the solution is regular.

description: The dominant mechanism for the central exclusive production of vector meson in $p p$ and $p \bar p$ collisions is the $γ$ $I P$ fusion. As a building block for the pp reaction, the amplitude for photoproduction $ γp \to V p $ is calculated in a pQCD $k_{T}$- factorization approach. We will present results for several vector mesons: $ρ$, $ω$, $ϕ$, $J/Ψ$ and $Υ$. The total cross section for diffractive mesons production as a function of energy and photon virtuality is calculated. We will present dependence on the mass of the quark for light mesons. The results for $ γp \to V p $ photoproduction depend on the model of the meson wave function. We compare our results with a HERA data for photon-proton collisions. Finally we turn to pp collisions, and we present distribution in rapidity, transverse momentum of vector mesons and azimuthal angle between outgoing protons for Tevatron and LHC energies. The absorption effects will be discussed.

description: Spherical clusters of SU(2) BPS monopoles are investigated here. A large class of monopole solutions is found using an abelian approximation, where the clusters are spherically symmetric, although exact solutions cannot have this symmetry precisely. Monopole clusters generalise the Bolognesi magnetic bag solution of the same charge, but they are always larger. Selected density profiles give structures analogous to planets of uniform density, and galaxies with a density decaying as the inverse square of the distance from the centre. The Bolognesi bag itself has features analogous to a black hole, and this analogy between monopole clusters and astrophysical objects with or without black holes in their central region is developed further. It is also shown that certain exact, platonic monopoles of small charge have sizes and other features consistent with what is expected for magnetic bags.

Application of SCODA to forensic exhibits

description: Since law enforcement first used DNA evidence to solve crimes in 1985, DNA typing and the comparison of STR (Short Tandem Repeat) profiles have become the accepted gold standard in forensic science for identification. Although common DNA extraction methods such as phenol-chloroform extraction and silica binding matrices are often effective, a small percentage of samples fail to yield a profile. Some types of samples, for example bones or bloodstains on concrete, are particularly challenging due to environmental degradation of the DNA and high concentrations of PCR inhibitors relative to the amount of available DNA. This ultimately makes obtaining a DNA profile very difficult and sometimes impossible for this class of samples. This thesis introduces SCODA (Synchronous Coefficient of Drag Alteration) as a novel electrophoretic nucleic acid clean-up method for purifying trace amounts of DNA from PCR inhibited forensic samples. Unlike other extraction techniques that rely on the chemical properties of DNA, SCODA takes advantage of the physical properties unique to long and charged molecules such as nucleic acids to selectively concentrate them in an agarose gel matrix. SCODA was compared to other extraction and purification methods to determine the best method for obtaining DNA profiles from difficult forensic samples. Samples that were examined included bones, bloodstains on concrete and two actual forensic exhibits. DNA yield and PCR inhibition were assessed by quantitative PCR and STR analysis was conducted to ensure that profiles could be obtained. In summary, it has been found that SCODA is optimal for highly inhibited samples that mask the presence of DNA, as in some cases of bone, and that specific protocols can be designed to further improve SCODA to outperform other extraction methods, which are more difficult to customize.

Hurricane Katrina (2005)

description: This fact sheet provides a portrait of poor children in the Gulf Coast states ravaged by Hurricane Katrina. New Orleans and the surrounding region have long been home to some of the poorest children in the country. Over 13% of children in Louisiana live in extreme poverty—that is, in families with an income less than half of the federal poverty level, or $9,675 for a family of four—compared to a national average of 7%. These children are disproportionately African American. These were, and are, families left behind, physically trapped in areas of Louisiana, Mississippi, and Alabama because they also are trapped by poverty. They had no way out because they have few resources—cash, assets, credit cards, bank accounts, cars, and more. Before Katrina, these families experienced hardship, hunger, and other circumstances that make it difficult for children to thrive. Now many face far worse conditions.

description: Background: Research priority setting is a useful approach to decide which unanswered questions are most worth trying to solve through research. The aim is to reduce bias in the research agenda. Traditionally, research was decided by funders, policymakers, and academics with limited infuence from other stakeholders like people living with health conditions, caregivers, or the community. This can lead to research gaps that fail to address these important stake-holder needs. The objective of this study is to identify the top research priorities for Rheumatic and Musculoskeletal Disease (RMD) research in Ireland. Methods: The process framework included a design workshop, two online surveys and a review of the literature. Participants: 545 people completed the frst survey to identify RMD research topics relevant to Ireland, of which 72% identifed as a person living with RMD. 460 people completed the second survey to prioritise these research topics. Results: The frst survey had 2185 research topics submitted. These were analysed and grouped into 38 topic areas which were ranked in the second survey. The top three research priorities for RMD research in Ireland focused on preventing RMD progression, RMD diagnosis and its impact, and pain management. Conclusions: The prioritised research topics indicate important areas of RMD research for Ireland. Research funded in response to these co-created research priorities will have increased relevance and impact.
Adolescent Violence and Unintentional Injury in the United States

description: Overall rates of injury and death increase dramatically from childhood to late adolescence. Due to developmental and social factors, such as time spent without adult supervision and increasing independence, adolescents are more likely to engage in risk-taking behaviors than either younger children or adults. Biology also plays a role. The maturation of brain networks responsible for self-regulation often does not occur until late adolescence, making adolescents more likely to engage in risk-taking behaviors. These are just a few of the factors that contribute to greater risk of injury or violence in this age group. Violence and unintentional injury are two of the interrelated areas of vulnerability that adolescents may encounter. Combined with problems related to mental health, sexual and reproductive health, substance use, and nutrition and obesity, violence and unintentional injury form part of a complex web of potential challenges to adolescents' health.

description: For some time domestic violence has been recognized as an issue with profound implications for our society. Recently, evidence has accumulated to document in particular the effects of domestic violence on poor families. The welfare reform proposals of the mid 1990s drew attention to the problem of domestic violence among individuals receiving public assistance who are among the poorest of the poor. With the passage of the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) in 1996—the welfare legislation that replaced Aid to Families with Dependent Children (AFDC) with Temporary Assistance for Needy Families (TANF)—provisions were included to allow exemptions from work requirements for victims of domestic violence. Considerable research prior to 1996 and subsequently has produced relevant findings about the impact of domestic violence on employment and self-sufficiency. This research has also highlighted factors which complicate identifying and assessing the existence of domestic violence, most often related to the reticence of the victim to discuss the problem for very personal reasons. Current PRWORA reauthorization efforts have continued and expanded a focus on employment and self-sufficiency, but have also increased a focus on child well-being and marriage. Child well-being and marriage formation are subjects that are intricately related to stable relationships between adults interested in rearing healthy and happy children. This report examines what is known from past research on domestic violence that may inform policies related to marriage and child well-being. In addition, it highlights areas for future research and strategies that can advance stable marriages and improve the well-being of children who otherwise might suffer the effects of domestic violence.

description: SHELS (Smithsonian Hectospec Lensing Survey) is a dense redshift survey covering a 4 square degree region to a limiting R = 20.6. In the construction of the galaxy catalog and in the acquisition of spectroscopic targets, we paid careful attention to the survey completeness for lower surface brightness dwarf galaxies. Thus, although the survey covers a small area, it is a robust basis for computation of the slope of the faint end of the galaxy luminosity function to a limiting M_R = -13.3 + 5logh. We calculate the faint end slope in the R-band for the subset of SHELS galaxies with redshif ts in the range 0.02 <= z < 0.1, SHELS_{0.1}. This sample contains 532 galaxies with R< 20.6 and with a median surface brightness within the half light radius of SB_{50,R} = 21.82 mag arcsec^{-2}. We used this sample to make one of the few direct measurements of the dependence of the faint end of the galaxy luminosity function on surface brightness. For the sample as a whole the faint end slope, alpha = -1.31 +/- 0.04, is consistent with both the Blanton et al. (2005b) analysis of the SDSS and the Liu et al. (2008) analysis of the COSMOS field. This consistency is impressive given the very different approaches of th ese three surveys. A magnitude limited sample of 135 galaxies with optical spectroscopic reds hifts with mean half-light surface brightness, SB_{50,R} >= 22.5 mag arcsec^{-2} is unique to SHELS_{0.1}. The faint end slope is alpha_{22.5} = -1.52+/- 0.16. SHELS_{0.1} shows that lower surface brightness objects dominate the faint end slope of the l uminosity function in the field, underscoring the importance of surface brightness limits in evaluating measurements of the faint end slope and its evolution.
