description: Liganden basierend auf 3-Formylacetylaceton sind aufgrund der chelatisierenden Iminenolatfunktion von Interesse für die Synthese von Metallkomplexen. Das Koordinationsverhalten dieser Gruppe kann durch eine weitere Donorgruppe beeinflusst werden. Tridentate Iminenolatliganden, die zusätzlich mit NHC- bzw. Thioetherfunktionen substituiert sind und die Synthese von Komplexen dieser Liganden mit zweiwertigen 3d-Metallen werden vorgestellt. Die Deprotonierung der korrespondierenden Immidazoliumsalze zu NHC-Liganden in Gegenwart von Metallionen führt zur Bildung von monomeren Komplexen der allgemeinen Formel [M(Lt2)] (M = Fe, Co, Ni, Cu). Pentadentate Liganden können ausgehend von zweifach NH2-funktionalisierten Edukten erhalten und mit Metall(II)-acetaten zu Komplexen der Formel [M(Lp)] umgesetzt werden. Die Synthese eines derartigen Immidazoliumsalzes wird beschrieben. Die Verbindungen wurden mittels spektroskopischer Methoden und Röntgeneinkristallstrukturanalyse charakterisiert.
description: Ligands based on 3-formylacetylacetone are of interest due to their chelating imine enolate function for the synthesis of metal complexes. The introduction of another donor group influences the coordination behavior of that imine enolate group. Tridentate ligands derived from 3-formylacetylacetone and amines with NHC- or thioether functions as well as the synthesis of their 3d-metal complexes are presented. Deprotonation of the corresponding imidazolium salt in the presence of metal ions yields monomeric complexes of the general formula [M(Lt)2] (M = Fe, Co, Ni, Cu). Pentadentate ligands can be prepared from 3-formylacetylacetone and two times NH2-functionalized educts. Those react with metal acetates under formation of complexes [M(Lp)]. The synthesis of two times NH2-functionalized imidazolium salts from phenylene diamines is described. Characterization of the compounds was done by spectroscopic methods and single crystal X-Ray diffraction.

description: Background: While short-term effects of weight loss on quality of life and metabolic aspects appear to be different in metabolically healthy (MHO) and metabolically unhealthy obese (MUO), respective long-term data is still missing. Given the high relevance of long-term changes, we aimed to address these in this post-hoc analysis of the MAINTAIN trial. Methods: We analyzed 143 overweight/obese subjects (BMI >= 27 kg/m(2), age >= 18 years) before and after a 3-month weight loss program (>= 8% weight loss), after a 12-month period of a randomized weight maintenance intervention (n =121), and after another 6 months without intervention (n=112). Subjects were retrospectively grouped into MHO and MUO by the presence of metabolic syndrome and secondarily by estimates of insulin sensitivity (HOMA-IR and ISIclamp). Quality of life (QoL), blood pressure, lipids, HOMA-IR, and ISIclamp were assessed and evaluated using mixed model analyses. Results: Despite similar short- and long-term weight loss, weight loss-induced improvement of HOMA-IR was more pronounced in MUO than MHO after 3 months (MHO: 2.4[95%-CI: 1.9-2.9] vs. 1.6[1.1-2.1], p= 0.004; MUO: 3.6[3.2-4.0] vs. 2.0[1.6-2.4], p < 0.001; p= 0.03 for inter-group comparison). After 21 months, the beneficial effect was no longer seen in MHO (2.0[1.5-2.6], p= 1.0), while it remained partially preserved in MUO (2.9[2.4-3.3], p= 0.002). QueryShort-term improvements of lipid parameters were similar in both groups. However, long-term improvements of HDL-cholesterol and triglycerides were only seen in MUO (44.4[41.5-47.4] vs. 49.3[46.2, 52.3] mg/dl, p < 0.001; 176.8[158.9-194.8] vs. 138.8[119.4-158.3] mg/dl, p < 0.001, respectively) but not in MHO. Weight loss-induced improvements in the QoL and particularly the physical health status were maintained in MUO until the end of the trial, while benefits disappeared over time in MHO. Group allocation by HOMA-IR and ISIclamp revealed higher benefits for MUO mainly in parameters of the glucose metabolism and QoL. Conclusions: Our data demonstrates stronger and longer-lasting improvements of metabolism and QoL in MUO after weight loss.

Microbial inhibition of methane clathrate hydrates
Creators: name: Townson, Iwan Meredydd
Publisher: name: University of British Columbia

description: Two microbial species were tested for inhibition of methane hydrates in a stirred crystallizer (subcooling of 2.34 K). The ice associating Chryseobacterium sp. Strain C14, grown in 0.5 wt% Tryptic Soy Broth (TSB) delayed hydrate nucleation, on average, by 30.3 hours compared to 37.9 hours for the PVP solutions. Escherichia coli TG2 in 0.5 wt% TSB was used as a non ice associating bacteria control and surprisingly had the longest induction period of 118.1 hours, suggesting that it was 3 times more effective as a hydrate inhibitor than PVP. The 0.5 wt% aq. TSB solution without bacteria delayed hydrate nucleation an average of 6.7 hours, whilst bacteria without TSB also showed significant inhibition. However, for the bacteria and bacteria + TSB systems, nucleation times were far more sporadic and time dependant than the simple systems of pure water and PVP. PVP decreased hydrate growth rate but increased gas consumption by nearly 4 fold. TSB without bacteria promoted gas consumption by over 2 fold but exhibited a slightly higher growth rate than the pure water solution. Reasons for the differences in growth profiles may be a result of the observed morphological differences in the hydrate phase. Chryseobacterium in 0.5 wt% aq. TSB had a distinct time dependency in growth characteristics and promoted growth rate almost 3 fold. E. coli in 0.5 wt% TSB showed a unique S-curve growth profile where the initial growth rate was very low. The differences in growth profiles of the two bacteria suggest different inhibition mechanisms. Ice-associating proteins likely play a significant role in hydrate formation, especially for Chryseobacterium which has shown inhibition of ice recrystallization. However, the interaction of other non-ice associating macromolecules may play a primary role in the observed inhibition and that biofilm formation may act as a barrier between the gas-liquid and/or heterogeneous nucleating solid-liquid interfaces which may help explain the significant inhibition observed by E. coli. Considering that both species of bacteria yielded significant hydrate inhibition, albeit somewhat unpredictable, but since the procedure is simple, the potential of employing bacteria as ‘Microbial Hydrate Inhibitors’ looks promising. However, consistent inhibition will be a challenge to overcome so that these organisms could be used as other KHI solutions.

description: The macroscopic tunneling of an optomechanical membrane is considered. A cavity mode which couples quadratically to the membranes position can create highly tunable adiabatic double-well potentials, which together with the high Q-factors of such membranes render the observation of macroscopic tunneling possible. A suitable, pulsed measurement scheme using a linearly coupled mode of the cavity for the verification of the effect is studied.

description: Die Arbeit beschäftigt sich mit der Ausprägung des Schwanzes beim Schwein. Ziel der Untersuchung war es, die Variabilität der Schwanzlänge und weiterer Merkmale, wie dem Schwanzdurchmesser, der Körperlänge oder dem Gewicht, zu erheben. Darüber hinaus sollten Einflüsse auf die Merkmale ermittelt, sowie Heritabilitäten und Korrelationen berechnet werden. Zudem stand die weitere Entwicklung der Ferkel in Abhängigkeit von der Schwanzlänge im Blickpunkt. Auch die Ausprägung von Schwanzanomalien sowie die Anzahl der Schwanzwirbel wurden untersucht. Die Datenerfassung erfolgte vorrangig in einem Basiszuchtbetrieb, wo unter Reinzucht 6.428 Piétrain-Ferkel untersucht wurden. Dabei wurde eine mittlere Schwanzlänge von 8,69 ± 0,99 cm festgestellt. Die Gesamtvariabilität ist sehr hoch. Aus der direkten Heritabilität von hd²=0,31 ± 0,03 ergibt sich ein hohes züchterisches Potenzial, dem jedoch die großen Abhängigkeiten zum Geburtsgewicht und der späteren Entwicklung der Ferkel entgegenstehen.
description: This paper is about the expression of the tail in pigs. The aim of the study was to determine the phenotypic and genetic variability of the tail length and other physical features, such as the diameter of the tail, the body length, or the weight of the piglets. Moreover, influences on the characteristics were investigated, heritabilities and correlations calculated and additionally, the future growth of the piglets depending on the tail length examined. Part of this study also was the investigation of tail abnormalities and the number of caudal vertebrae. The biggest part of the data collection for 6,428 pure Piétrain pigs took place in a nucleus line. As a result, the tail length of the piglets was 8.69 ± 0.99 cm. There is a big total variability and a possibility to influence the tail length by breeding, which is supported by a direct heritability of hd²=0.31 ± 0.03. However, this possibility is hindered by the dependence to the birth weight and the poor development of the piglets.

description: Passive red galaxies frequently contain warm ionized gas and have spectra similar to low-ionization nuclear emission-line regions (LINERs). Here we investigate the nature of the ionizing sources powering this emission, by comparing nuclear spectroscopy from the Palomar survey with larger aperture data from the Sloan Digital Sky Survey. We find the line emission in the majority of passive red galaxies is spatially extended; the Halpha surface brightness profile depends on radius (r) as r^(-1.28). We detect strong line ratio gradients with radius in [N II]/Ha, [S II]/Ha, and [O III]/[S II], requiring the ionization parameter to increase outwards. Combined with a realistic gas density profile, this outward increasing ionization parameter convincingly rules out AGN as the dominant ionizing source, and strongly favors distributed ionizing sources. Sources that follow the stellar density profile can additionally reproduce the observed luminosity-dependence of the line ratio gradient. Post-AGB stars provide a natural ionization source candidate, though they have an ionization parameter deficit. Velocity width differences among different emission lines disfavor shocks as the dominant ionization mechanism, and suggest that the interstellar medium in these galaxies contains multiple components. We conclude that the line emission in most LINER-like galaxies found in large aperture (>100pc) spectroscopy is not primarily powered by AGN activity and thus does not trace the AGN bolometric luminosity. However, they can be used to trace warm gas in these red galaxies.

description: Peer-to-Peer (P2P) systems have proved to be the most effective and popular file sharing applications in recent years. Previous studies mainly focus on the equal service and the differentiated service strategies when peers have no initial data before their download. In an upload-constrained P2P file sharing system, we model both the equal service process and the differentiated service process when peers' initial data distribution satisfies some special conditions, and also show how to minimize the time to get the file to any number of peers. The proposed models can reveal the intrinsic relations among the initial data amount, the size of peer set and the minimum last finish time. By using the models, we can also provide arbitrary degree of differentiated service to a certain number of peers. We believe that our analysis process and achieved theoretical results could provide fundamental insights into studies on bandwidth allocation and data scheduling, and can give helpful reference both for improving system performance and building effective incentive mechanism in P2P file sharing systems.
Automatic Segmentation and Part-Of-Speech Tagging For Tibetan: A First Step Towards Machine Translation

description: This paper presents what we believe to be the first reported work on Tibetan machine translation (MT). Of the three conceptually distinct components of a MT system — analysis, transfer, and generation — the first phase, consisting of POS tagging has been successfully completed. The combination POS tagger / word-segmenter was manually constructed as a rule-based multi-tagger relying on the Wilson formulation of Tibetan grammar. Partial parsing was also performed in combination with POS-tag sequence disambiguation. The component was evaluated at the task of document indexing for Information Retrieval (IR). Preliminary analysis indicated slightly better (though statistically comparable) performance to n-gram based approaches at a known-item IR task. Although segmentation is application specific, error analysis placed segmentation accuracy at 99%; the accuracy of the POS tagger is also estimated at 99% based on IR error analysis and random sampling.

description: A complete classification of non-affine dynamical quantum $R$-matrices obeying the ${\mathcal G}l_n({\mathbb C})$-Gervais-Neveu-Felder equation is obtained without assuming either Hecke or weak Hecke conditions. More general dynamical dependences are observed. It is shown that any solution is built upon elementary blocks, which individually satisfy the weak Hecke condition. Each solution is in particular characterized by an arbitrary partition ${{\mathbb I}(i), i\in{1,...,n}}$ of the set of indices ${1,...,n}$ into classes, ${\mathbb I}(i)$ being the class of the index $i$, and an arbitrary family of signs $(ε_{\mathbb I})_{{\mathbb I}\in{{\mathbb I}(i), i\in{1,...,n}}}$ on this partition. The weak Hecke-type $R$-matrices exhibit the analytical behaviour $R_{ij,ji}=f(ε_{{\mathbb I}(i)}Λ_{{\mathbb I}(i)}-ε_{{\mathbb I}(j)}Λ_{{\mathbb I}(j)})$, where $f$ is a particular trigonometric or rational function, $Λ_{{\mathbb I}(i)}=\sum\limits_{j\in{\mathbb I}(i)}λ_j$, and $(λ_i)_{i\in{1,...,n}}$ denotes the family of dynamical coordinates.

description: Background: Postural control is associated with fall risk. Patients with rheumatoid arthritis (RA) have a higher risk to fall than healthy subjects. The objective of this study was to identify associations between variables of postural control with prospective falls in patients with RA. Methods: For the baseline, the balance performance of 289 men and women with RA, ages 24-85 years, was evaluated by SPPB, FICSIT-4 and Romberg tests. Postural sway for Romberg, semitandem, tandem and one-leg stands were measured with the Leonardo Mechanograph (R). Self-reported disability was assessed using the Health Assessment Questionnaire (HAQ) and the Activity-specific Balance Confidence Scale (ABC-scale). Falls were reported in quarterly reports over a year. Univariate and multiple logistic regression analysis were used to explore any associations with falling. Receiver-operating characteristics were determined, and the area under the curve is reported. Results: A total of 238 subjects completed the 1-year follow-up, 48 (20.2%) experienced at least one fall during the observational period. Age (OR = 1.04, CI 1.01-1.07), HAQ (OR = 1.62, 1.1-2.38), FICSIT-4 scoring 0-4 (OR = 2.38, 1.13-5.0), and one-leg standing (OR = 2.14, 1.06-4.31) showed significant associations with falls. With regard to the SPPB and ABC-scale, no statistically significant associations with falls were found. The quartiles containing the worst results of medio-lateral sway of Romberg (OR = 2.63, CI 1.03-6.69), total sway of semitandem (OR = 3.07, CI 1.10-8.57) and tandem (OR = 2.86, CI 1.06-7.69), and area of sway of semitandem (OR = 2.80, CI 1.11-7.08) stands were associated with falls. Conclusions: The assessment of a one-leg stand seems to be a good screening tool to discriminate between high and low risk of falls in RA patients in clinical practice. A low FICSIT-4 score and several sway parameters are important predictors of falls.

description: Background: During the COVID-19 pandemic, shortage of nursing staff became even more evident. Nurses experienced great strain, putting them at risk to leave their jobs. Individual and organizational factors were known to be associated with nurses' turnover intention before the pandemic. The knowledge of factors associated with turnover intention during the pandemic could help to foster nurses' retention. Therefore, this review aims to identify factors associated with nurses' turnover intention during the COVID-19 pandemic. Methods: After a systematic search of six databases, the resulting records were screened in a two-step process based on pre-defined inclusion and exclusion criteria. The included quantitative studies were synthesized qualitatively due to their methodological heterogeneity. Results: A total of 19 articles were included in the analysis. Individual factors such as health factors or psychological symptoms and demographic characteristics were associated with nurses' turnover intention. Organizational factors associated with turnover intention were e.g., caring for COVID-19 patients, low job control or high job demands, and moral distress. Resilience and supporting leadership could mitigate adverse associations with turnover intention. Conclusions: The results help to identify high-risk groups according to individual factors and to develop possible interventions, such as trainings for nurses and their superiors, addressing individual and organizational factors. Future research should focus on longitudinal designs applying carefully defined concepts of turnover intention.

Mittels Fragebogen wurden Prävalenz und Charakteristik eines experimentell provozierten HICS durch Eiswürfel- und Eiswasserprovokation bei 79 Probanden mit Migräne untersucht. Die Methodik richtet sich nach der Vorgängerstudie Mages et al. Der provozierte HICS tritt nach Eiswasserprovokation (59%) signifikant häufiger als nach Eiswürfelprovokation (24%) auf. Eiswürfel löst HICS häufiger bei Probanden mit als ohne Migräne aus. Ein F-HICS tritt bei 18% der Probanden auf. Der HICS ist wie die Migräne unilateral. Latenz und Dauer liegen unter 30 Sekunden. Der HICS hat eine Intensität zwischen 3 bis 5 mit stechend, drückendem Charakter. Lakrimation ist das häufigste Begleitsymptom. Man geht davon aus, dass das Trigeminoautonome System in der Pathophysiologie involviert ist. Die Ergebnisse ermöglichen eine Anpassung der Diagnosekriterien für den HICS.
description: Ice cream headache is described in ICHD-3 as “headache attributed to ingestion or inhalation of a cold stimulus” (HICS). Using a questionnaire, the prevalence and characteristics of an experimentally provoked HICS by ice cube and ice water provocation were investigated in 79 subjects with migraine. The method is based on the previous study Mages et al. Provoked HICS occurs significantly more frequently after ice water stimulation (59%) than after ice cube stimulation (24%). Ice cube provocation elicits HICS more frequently in subjects with than without migraine. F-HICS occurs in 18% of the subjects. Like migraine headache, HICS is unilateral. Latency and duration are less than 30 seconds. The HICS has an intensity between 3 and 5 with stabbing and pressing character. Lacrimation is the most common attendant symptom. The trigeminal autonomic system is believed to be involved in pathophysiology. The results allow an adjustment of the diagnostic criteria for the HICS.

number of African-Americans in investment banking.
Although most of the past research in Cultural Capital has been on the racial disparities in
participation of the arts, the principal investigator (PI) will look to prove that the racial
disparities in the investment banking industry are due to a lack of cultural capital that is
necessary to succeed in the industry. Essentially, the principal investigator is interested in the
effects of cultural capital on African-American success rates and interest in investment banking.

However, the occupation did not absolutely determine the socioeconomic situation of an active German community, much less workers’ identities or poets’ inspiration.

description: A growing number of solar-like oscillations has been detected in red giant stars thanks to CoRoT and Kepler space-crafts. The seismic data gathered by CoRoT on red giant stars allow us to test mode driving theory in physical conditions different from main-sequence stars. Using a set of 3D hydrodynamical models representative of the upper layers of sub- and red giant stars, we computed the acoustic mode energy supply rate (Pmax). Assuming adiabatic pulsations and using global stellar models that assume that the surface stratification comes from the 3D hydrodynamical models, we computed the mode amplitude in terms of surface velocity. This was converted into intensity fluctuations using either a simplified adiabatic scaling relation or a non-adiabatic one. From L and M (the luminosity and mass), the energy supply rate Pmax is found to scale as (L/M)^2.6 for both main-sequence and red giant stars, extending previous results. The theoretical amplitudes in velocity under-estimate the Doppler velocity measurements obtained so far from the ground for red giant stars by about 30%. In terms of intensity, the theoretical scaling law based on the adiabatic intensity-velocity scaling relation results in an under-estimation by a factor of about 2.5 with respect to the CoRoT seismic measurements. On the other hand, using the non-adiabatic intensity-velocity relation significantly reduces the discrepancy with the CoRoT data. The theoretical amplitudes remain 40% below, however, the CoRoT measurements. Our results show that scaling relations of mode amplitudes cannot be simply extended from main-sequence to red giant stars in terms of intensity on the basis of adiabatic relations because non-adiabatic effects for red giant stars are important and cannot be neglected. We discuss possible reasons for the remaining differences.

description: Objectives: To investigate sonication as a new tool in microbiological probing of dental infections. Methods: Comparison of a standard probing method: intraoperative swab, with sonication, and vortex of the removed tooth, was performed on 20 carious destructed teeth. Illumina high throughput sequencing of the 16S-rRNA-gene was used for assessing the microbial composition. Antibiotic susceptibility has been assigned based on known resistances of each detected species. Probing procedures were compared using Bland-Altmann-Test, and antibiotic susceptibility using the Friedmann-Test and alpha-adjusted post-hoc-analysis. Results: In total, 60 samples were analysed: 20 intraoperative swabs, 20 vortex fluids, and 20 sonication fluids. Sonication fluid yielded the highest number of bacterial sequencing reads in all three procedures. Comparing the operational taxonomic units (OTUs) of the identified bacteria, significantly more OTUs were found in sonication fluid samples. Phylum and order abundances varied between the three procedures. Significantly more Actinomycetales have been found in sonication fluid samples compared to swab samples. The assigned resistance rates for the identified bacteria (1.79-31.23%) showed no differences between the tested probing procedures. The lowest resistance rates were found for amoxicillin + clavulanate (3.95%) and levofloxacin (3.40%), with the highest in amoxicillin (30.21%) and clindamycin (21.88%). Conclusions: By using sonication on extracted teeth, it is possible to get a more comprehensive image of the residing microbial flora compared to the standard procedure. If sonication is not available, vortexing is a potential alternative. In immunocompromised patients, especially when actinomycosis is suspected, sonication should be considered for a more detailed microbiological evaluation of the potential disease-causing microbiome. Due to the high rates of antibiotic resistance, a more targeted antibiotic therapy is favourable. Levofloxacin should be considered as a first-line alternative to amoxicillin + clavulanate in patients with an allergy to penicillin.

description: In The Formation of the Hebrew Bible: A New Reconstruction (New York: Oxford, 2011), David Carr rethinks both the methods and historical orientation points for research on the growth of the Hebrew Bible into its present form. Building on his prior work, Writing on the Tablet of the Heart (New York: Oxford, 2005), he explores both the possibilities and limits of reconstruction of pre-stages of the Bible. He advocates a "methodologically modest"  investigation of those pre-stages, utilizing criteria and models derived from his survey of documented examples of textual revision in the Ancient Near East. The result is a new picture of the formation of the Hebrew Bible, with insights on the initial emergence of Hebrew literary textuality, the development of the first Hexateuch, and the final formation of the Hebrew Bible. Some have advocated dating the bulk of the Hebrew Bible in a single period, whether relatively early (Neo-Assyrian) or late (Persian or Hellenistic), but Carr uncovers specific evidence that the Hebrew Bible contains texts dating across Israelite history, even the early pre-exilic period (10th-9th centuries). He traces the impact of Neo-Assyrian imperialism on eighth- and seventh-century Israelite textuality, and uses studies of collective trauma to identify marks of the reshaping and collection of traditions in response to the destruction of Jerusalem and Babylonian exile. Carr also develops a picture of varied Priestly reshaping of narrative and prophetic traditions in the Second Temple period, including the move toward eschatological and apocalyptic themes and genres. In addition, he uses manuscript evidence from Qumran and the Septuagint to find clues to the final literary shaping of the proto-Massoretic text, likely under the Hasmonean monarchy.

description: Sensorische Nervenendigungen wurden an elf humanen Ellenbogengelenken in der Capsula articularis, im Ligamentum collaterale ulnare, im Ligamentum collaterale radiale und im Ligamentum anulare radii mit den Antigenen Proteingenprodukt 9,5, Neurotrophinrezeptor p75, S100B-Protein, Smooth-Muscle-Aktin, Carboanhydrase 2 und Cholinacetyltransferase in der Immunfluoreszenz analysiert. Die Innervation fand sich epifaszikulär konzentriert und zwischen den Insertionen gleichmäßig verteilt. Dominanter Rezeptortyp war die freie Nervenendigung, als Nozizeptor am dichtesten in der anterioren Gelenkkapsel, gefolgt von Ruffini-Endigungen, zur Detektion der Gelenkposition im Ligamentum collaterale ulnare pars anterior überwiegend, und nichtklassifizierbaren Korpuskeln. Am wenigsten bestimmt wurden Golgi-ähnliche Endigungen, vorwiegend im Ligamentum collaterale radiale zur Wahrnehmung extremer Gelenkpositionen, und Pacini-Korpuskel. Korrelationen im Auftreten waren positiv und die Innervation sensibel.
description: Sensory nerve endings were analyzed in eleven human elbow joints in the articular capsule, ulnar collateral ligament, radial collateral ligament, and annular ligament by immunofluorescence staining with protein gene product 9.5, neurotrophin receptor p75, S100B protein, smooth muscle actin, carbonic anhydrase 2, and choline acetyltransferase. The mechanoreceptors were found to be concentrated epifascicularly and distributed evenly between bony insertions. Free nerve endings were the dominant receptor type, mainly localized in the anterior joint capsule for nociception, followed by Ruffini endings detecting the joint position sense predominantly in the anterior part of the ulnar collateral ligament, and nonclassifiable corpuscles. Golgi-like endings, densest in the collateral radial ligament for perception of extreme joint positions, and Pacini corpuscles were least abundant. The correlations in the occurrence of sensory nerve endings were positive and innervation was sensitive.

description: Hospice care delivered by an interdisciplinary team of professional staff includes care of those individuals with a life-limiting illness and a prognosis of days to a few months. It serves a variety of individuals with a combination of multiple diseases and co-morbidities and provides support for their families. A skilled health workforce is needed to deliver quality hospice and palliative care services. Inconsistencies in hospice staff knowledge and provided education have been identified locally in Alberta and across Canada. In previous studies, hospice nurses have identified knowledge deficits in pain and symptom management, psychological and spiritual care, and communication with dying patients. This research, engaging a focused ethnographic methodology, occurred at a local 26-bed hospice. I immersed myself in the hospice culture and in the research process to understand ways that the culture of hospice care can shape the educational needs of professional hospice staff. Data consisted of semi-structured interviews of hospice staff key participants, observations of interdisciplinary hospice professionals during their daily work, examination of hospice cultural documents and artifacts, and the writing of field notes over three months. The study findings suggest that at the core of the hospice staff educational needs lies three primary themes: communication as an essential foundation of quality care; interdisciplinary collaboration is vital for team cohesiveness and lastly, the central care philosophy utilized by the hospice interdisciplinary team is person/resident and family-centered care. These findings offer suggestions for hospice education and further research. Relational care is foundational for this philosophy, with trusting relationships at the forefront of care.

description: Las proyecciones hacia el futuro determinan que podría haber un aumento de hasta 1,7°C de temperatura para el 2050 y hasta 4°C para el final de este siglo, lo que sería catastrófico para la sostenabilidad de vida en el planeta, tal y como la conocemos hoy, Los niveles de aumento del nivel del mar han alcanzado 2 a 3 mm/año desde 1980 en la región. Han sido observados también cambios en los patrones de precipitaciones, con algunas áreas recibiendo más lluvias-sur de Brasil. Paraguay, Uruguay, nordeste de Argentina y noroeste de Perú-y otras con un menor nivel-sur de Chile, suroeste de Argentina y el sur de Perú. Finalmente los eventos climáticos extremos se han vuelto más comunes en varias partes de la región, incluyendo más períodos de lluvias intensas y más días de sequía consecutivos. Entre los sectores económicos de América Latina, el que probablemente sufrirá un impacto mayor y más directo, producto del cambio gradual de la temperatura y las precipitaciones, será la agricultura, También serán importantes, al menos desde una perspectiva local, los impactos económicos y sociales asociados con el aumento en la frecuencia y/o intensidad de los huracanes y tormentas tropicales, la desaparición de los glaciares tropicales en los Andes, el aumento de la tasa del nível del mar, el descoloramiento y eventual deterioro de los arrecifes de coral en el Caribe, la posible escasez de agua debido a los cambios en los patrones de las precipitaciones, y el esperado aumento de las tasas de mortalidad y morbilidad derivados de los impactos del cambio climático sobre la incidencia de diversas enfermedades. Los pronósticos apuntan a que las pérdidas serían mayores en las zonas cercanas al Ecuador, mostrando posibles ganancias en algunas zonas en el Pacífico yen el sur del continente.

description: To properly implement a simple Tibetan Information Retrieval (IR) system segmentation of one form or another (n-gram, POS-tagging, dictionary substring matching, etc.) must be performed (see Hackett (2000b)). To take Tibetan indexing to a more sophisticated level however, some form of topic detection must be employed. This paper reports the results of a pilot study on the application to Tibetan of one technique for topic boundary detection: Lexical Cohesion. The resources developed and deployed, the theoretical model used, and its potential applications are discussed.

description: We consider a planar waveguide with "twisted" boundary conditions. By twisting we mean a special combination of Dirichlet and Neumann boundary conditions. Assuming that the width of the waveguide goes to zero, we identify the effective (limiting) operator as the width of the waveguide tends to zero, establish the uniform resolvent convergence in various possible operator norms, and give the estimates for the rates of convergence. We show that studying the resolvent convergence can be treated as a certain threshold effect and we present an elegant technique which justifies such point of view.

description: Background: Care homes were hit hard by the COVID-19 pandemic. Although high levels of psychosocial burden (i.e., anxiety, depression and stress) during the pandemic have been described for healthcare workers in hospitals, evidence on the psychosocial burden for nurses in care homes during the pandemic is scarce. Methods: A total of 811 nurses participated in a retrospective online survey between November 2020 and February 2021. Information about the COVID-19 situation (i.e., working demands, COVID-19 cases in their facility, and COVID-19-related burden) of nurses in German care homes during the first wave of the pandemic (March 2020 to June 2020) was gathered. The Stress Scale of the Depression Anxiety and Stress Scales (SDASS-21), the Generalized Anxiety Disorder Scale-2 (GAD-2), the Patients-Health-Questionnaire-2 (PHQ-2), and the Copenhagen Psychosocial Questionnaire (COPSOQ) were used to screen for psychosocial burden. Results: Among nurses, 94.2% stated that working demands since the COVID-19 pandemic increased. Further, 59.1% showed clinically relevant levels of either stress, anxiety, and/or depression. Multiple regression analysis showed significant associations between COVID-19-related burden and qualification (p < .01), dissatisfaction with COVID-19 management of care home manager (p < .05), COVID-19-related anxiety (p < .001), and dementia as a focus of care (p < .05). Stress, depression, and anxiety showed associations with COVID-19 related burden at work (p < .01), COVID-19-related anxiety (p < .001), social support (p < .01), and sense of community (p < .05). Stress was also associated with COVID-19 cases among residents (p < .05), and size of care home (p < .05). Conclusion: Short- and long-term strategies (i.e., psychosocial counseling, mandatory team meetings, more highly qualified nurses, additional training) in the work environment of nursing, in crises, but beyond, should be encouraged to reduce the burden on nursing staff in care homes.
