Establishing working relationships in online social work

Summary This article reports on an empirical case study into the process of establishing a working relationship between social workers and service users in an online social work service. Workers were using an online chat application to interact with young people, who sought professional help for various types of psychosocial problems. Two chat conversations and one interview of each of five research participants were analysed in terms of the way in which the working relationship between the service user and the online social worker was established. Thus, a total of 10 chat conversations and five interviews were included in this study. Findings Subjects were shown to be particularly focused on the process of addressing the issues with which the service users were trying to cope. As a consequence, limited effort was observed with regard to shaping the working relationship in such a way that the service user gained control over the course of the conversation. Applications As the medium influences the process of establishing a positive working relationship, it is argued that the worker should be able to understand the implications for the manner in which online conversations are conducted. Social work education is called upon to facilitate the acquiring of the knowledge and skills needed for such. It is suggested that more research into service users’ expectations regarding the working relationship within online social work could provide additional insights for the further improvement of these types of services.
Effects of 3-deazaadenosine on human promyelocytic HL-60 cells

The adenosine analog 3-deazaadenosine, which is known to perturb transmethylation reactions, and to promote conversion of 3T3-L1 cells inter adipocytes, was investigated with respect to its effect on growth, cloning efficiency and functional differentiation in the human promyelocytic cell line HL-60. 3-deazaadenosine showed growth inhibition and a moderate effect on functional differentiation at concentrations in the lower micromolar range. At higher concentrations (above 100 μM) the drug was cytotoxic and had a more pronounced effect on differentiation. These effects were associated with perturbation of metabolites of transmethylation and the formation of 3-deazaadenosylhomocysteine.
32S/34S isotope fractionation in plant sulphur metabolism

Summary Sulphur is a crucial microelement for plant metabolism, involved in response mechanisms to oxidative stress, C1 metabolism, electron transfer, secondary metabolism and post-translational peptide modifications. However, relatively little is known about sulphur transport and partitioning in plants. Although key steps of sulphur assimilation have been shown using labelling with radioactive 35S in past decades, the use of a natural tracer, allowing the examination of metabolic commitments and mass balance, is desirable. Sulphur stable isotopes (32S and 34S) have been proven to be useful for the investigation of the origin of sulphur atoms in geochemistry and for the detection of the origin of sulphur atoms. Nevertheless, their use for the study of primary sulphur metabolism has been impeded by our lack of knowledge of 32S/34S isotope fractionations and convenient methods for δ34S analyses. Here, we review documented 32S/34S isotope fractionations that may apply to sulphur metabolism, and explain how they should yield disparities amongst sulphur-containing plant compounds.
Practical oxygen therapy for newborn piglets

ABSTRACT Aims: To evaluate the effect of a novel method of practical oxygen therapy on physiological parameters related to survival, weaning weight and preweaning mortality of neonatal piglets under commercial farm conditions. Methods: Piglets from hyperprolific sows born with signs of asphyxia, (n = 109; <6 on a score of respiration, meconium staining and activity) or very low birth weight (VLBW; n = 112; <1.05 kg) were selected for the study. Approximately half of each group (n = 55 VLBW piglets and n = 57 piglets with asphyxia) received 100% oxygen immediately after birth using a specially designed facemask for 45 seconds (VLBW) or 1 minute (asphyxiated). Physiological parameters (peripheral blood oxygen saturation (SpO2) blood glucose concentration and rectal temperature) were measured before oxygen treatment 5 minutes after birth (SpO2) and 24 hours later (SpO2, blood glucose concentration, temperature). Weight at birth, at 24 hours and at 21 days of age, preweaning mortality, and estimated colostrum intake were also recorded. Results: A significant treatment effect on SpO2 was observed (p = 0.013 and p < 0.001 for VLBW and asphyxiated piglets respectively). VLBW and asphyxiated piglets that received oxygen treatment had higher SpO2 after treatment (measured 5 minutes after birth, 97.7 and 97.8% respectively) compared to immediately after birth (93.3 and 86.8% respectively) while untreated piglets showed no variation. Blood glucose concentrations increased in all piglets between birth and 24 hours of age (p = 0.003 and p < 0.001 for asphyxiated and VLBW piglets respectively) and this was higher in asphyxiated piglets that received oxygen than those that did not (5.6 (SE 0.2) mmol/L; p < 0.05). Estimated colostrum intake was higher in asphyxiated (401.6 (SD 24.4) g/kg) and VLBW (374.9 (SE 23.4 g/kg) piglets that received oxygen than those that did not (273.2 (SE 24.1) g/kg; p < 0.001 and 249.0 (SE 22.5) g/kg; p < 0.001 respectively). Similarly weight at weaning was higher in asphyxiated (5.8 (SE 0.2) kg) and VLBW (4.9 (SE 0.2) kg) piglets that received oxygen therapy than control animals (4.9 (SE 0.2) kg; = 0.005 and 4.1 (SE 0.2) kg; p = 0.008 respectively). Furthermore, oxygen treatment markedly reduced preweaning mortality from 9/52 (17%) untreated to 1/57 (1.7%) oxygen-treated piglets suffering asphyxia at birth (p = 0.006). Conclusions: Oxygen therapy improves physiological and productive parameters in piglets born with signs of asphyxia or VLBW. The incorporation of this strategy as part of the farrowing routine enhances the advantages of rearing hyperprolific sows.
Dynamics of the McArthur Basin diagenetic/hydrothermal system (Australia) : Timing and nature of fluid flow and constraints on the distribution of mineral resources (U, Cu, Pb-Zn)

The sedimentary McArthur Basin (Northern Territory and Queensland, Australia) is associated with numerous diagenetic/hydrothermal uranium, copper, lead and zinc concentrations, including some world-class deposits (e.g., Ranger and HYC). Some deposits correspond to styles of mineralisation well defined such as unconformity-type for uranium and Sediment-Hosted Massive Sulphide (SHMS) for lead-zinc, but others are not linked to a specific type. A major mineralising event at around 1650-1600 Ma is recorded in the uranium deposits in the North (Alligator Rivers Uranium Field – ARUF) and South (Westmoreland) parts of the basin and in lead-zinc deposits in the centre (Batten Fault Zone), and accounted for the exceptional metalliferous stock of the basin. In addition, even if it has not been established that the fluids responsible for uranium and lead-zinc mineralisation share a common origin, their characteristics in terms of temperature and salinity are similar. This PhD focused on the major factors controlling metals resources distribution at a large scale in this intracratonic sedimentary basin by studying the mineralisation with a geochronological and geochemical approach, and by characterising the associated fluids in order to define its age, temperature and emplacement conditions. In addition to the major event at 1650-1600 Ma, the metallogenic history of the basin shows numerous other evidences for crystallisation or remobilisation of the metalliferous stock. Some of the fluid circulation stages are linked with geodynamic events such as basin inversions or orogeneses located a few hundreds of kilometres from the studied area. It seems that the large scale migrations of mineralising fluids (i.e., overall horizontal in the large sandstone aquifers, and vertical in the major faults zones) allowed the metal mobilisation in different reservoirs from the basin and the basement, and their selective precipitation within favourable zones.
Parkinson's disease therapy with Istradefylline and blood biomarkers of epigenetics

Istradefylline (IST), an adenosine A2A receptor antagonist, has been used since 2013 in Japan as an adjunctive therapy to levodopa (L‐DOPA) for patients with Parkinson's disease (PD). The long‐term use of IST as an adjunct to L‐DOPA (IST‐LD) was herein investigated to clarify the cooperative potential to keep motor functions, and an epigenetic modification for disease‐specific up‐regulated A2AR signals.
ANTIBACTERIAL SURVEILLANCE: AN APPROACH TO MITIGATING MULTI-DRUG RESISTANCE MENACE AMONG CLINICAL UROPATHOGENS IN EKITI STATE, NIGERIA

Urinary tract infections (UTIs) are among the most common human infections with the distribution of etiological agents and antibiotic resistance patterns varying from region to region and from time to time. The aims of this study were to ascertain the prevalence and antibiotic resistance profiles of common Gram-negative uropathogens among patients attending a Tertiary Care Hospital in Ekiti State, Nigeria. One hundred and fifty clean-catch midstream urine specimens were obtained and cultured within 2 hours of collection for the detection of Gram-negative uropathogens. The isolated organisms were identified by standard microbiological methods. Of the total 150 urine specimens analyzed, 82 (54.67%) specimens were positive for Gram-negative uropathogen with significant bacteriuria of which 34 (41.46%) were males and 48 (58.54%) were females. Klebsiella spp. 38 (46.34%) and Escherichia coli 32 (39.02%) were the most frequently isolated Gram-negative uropathogens, followed by Proteus mirabilis 10 (12.20%) while the least occurring uropathogen was observed to be Pseudomonas aeruginosa 2 (2.44%). All the isolated uropathogens were observed to be highly resistant to the commonly prescribed antibiotics. Emerging resistance to carbapenems was also observed. Nevertheless, carbapenems showed highest susceptibility compared to other tested antibiotics. Conclusively, high levels of resistance of uropathogens to antibiotics exist in our setting. This therefore calls for continuous antibiotic surveillance and improved antibiotic stewardship.
Bovine tuberculosis in Michigan: stakeholder attitudes and implications for eradication efforts

Abstract Bovine tuberculosis (TB) has been discovered in unprecedented levels in Michigan's white-tailed deer (Odocoileus virginianus) herd. Human practices have facilitated the spread of bovine TB in white-tailed deer, and public cooperation is necessary to reduce the spread of the disease. Social data can determine public support for eradication strategies, as well as identify targets and messages for ongoing communication efforts. We conducted a survey of 5 bovine TB-issue stakeholder groups to assess and compare attitudes toward bovine TB-related topics and support for eradication and eradication policies. We also identified knowledge levels and interest in future bovine TB issue communications and preferences for communication sources. Results indicated that stakeholders supported the bovine TB eradication goal, but were less supportive of specific eradication policies. Stakeholders held different beliefs about threats posed by bovine TB, and about the means through which the disease is transmitted; stakeholder groups also had different levels of bovine TB-related knowledge. A strong majority of respondents (89%) were interested in being informed about new bovine TB issue-related information.
Effect of UHT Processing and Storage Conditions on Physico-chemical Characteristics of Buffalo Skim Milk

Summary: The obtained results indicated that physico-chemical and nutritional changes in UHT processed buffalo skimmed milk were more pronounced at 45°C than 25°C and 10°C. Duration of storage adversely affected the chemical and nutritional quality of processed milk. A slight decrease in pH, total ash and lactose contents, was observed, whereas acidity was increased on the mentioned storage conditions. Total nitrogen and casein nitrogen contents gradually decreased during storage, whereas non-casein nitrogen (NCN) and non-protein nitrogen (NPN) increased to a great extent in samples stored at higher temperatures. A significant increase in hydroxyl methyl furfural (HMF) values occurred in UHT processed buffalo skim milk at 25°C and 45°C after of 90 days storage. Storage at high temperature (45°C) caused undesirable effects on sensory properties, general quality characteristics and acceptability of UHT buffalo skimmed milk.
SELECTING AMONG AVAILABLE, ELITE TROPICAL MAIZE INBREDS FOR USE IN LONG-TERM TEMPERATE BREEDING 1

The narrowness of the temperate maize (Zea mays L.) germplasm base has long been recognized, and there are many available, elite tropical lines that might be used to profitably broaden it. However, there are few comparative yield-trial data by which to choose which line(s) might be most useful. As the investment re- quired for using a tropical line in a temperate breeding program is large, line-choice is critical. Here we report the results of testing a group of potentially-useful tropical lines in topcrosses grown in North Carolina. Results for 50%-exotic topcrosses and for 25%-exotic topcrosses are compared, and the 50%-exotic topcrosses with a broad- based tester (here, LH132.LH51) appear to be most effi- cient for initial screening. In addition, virtually all crosses suggested that any superior tropical line could be used equally well with either Stiff Stalk or non-Stiff Stalk germplasm. Of the 22 lines tested, CML258 and Tzi9 ap- pear to be the most promising, if yield improvement is a major criterion. None of the lines appeared to have seri- ous lodging, maturity or moisture problems in either 25% or 50%-tropical crosses.
Tree communities of white-sand and terra-firme forests of the upper Rio Negro

The high tree diversity and vast extent of Amazonian forests challenge our understanding of how tree species abundance and composition varies across this region. Information about these parameters, usually obtained from tree inventories plots, is essential for revealing patterns of tree diversity. Numerous tree inventories plots have been established in Amazonia, yet, tree species composition and diversity of white-sand and terra-firme forests of the upper Rio Negro still remain poorly understood. Here, we present data from eight new one-hectare tree inventories plots established in the upper Rio Negro; four of which were located in white-sand forests and four in terra-firme forests. Overall, we registered 4703 trees ≥ 10 cm of diameter at breast height. These trees belong to 49 families, 215 genera, and 603 species. We found that tree communities of terra-firme and white-sand forests in the upper Rio Negro significantly differ from each other in their species composition. Tree communities of white-sand forests show a higher floristic similarity and lower diversity than those of terra-firme forests. We argue that mechanisms driving differences between tree communities of white-sand and terra-firme forests are related to habitat size, which ultimately influences large-scale and long-term evolutionary processes.
Pseudohalonectria (Lasiosphaeriaceae), an antagonistic genus from wood in freshwater

Pseudohalonectria lignicola and five new species of Pseudohalonectria are described and illustrated from submerged wood in freshwater. Species are similar in overall morphology and produce bright yellow to brown perithecia, asci with thimbleshaped apical apparatuses and that separate from ascogenous hyphae at maturity, long, septate paraphyses attached to ascogenous hyphae, and hyaline to lightly pigmented phragmosporous ascospores. An anamorphic state was found for only one species. Pseudohalonectria has features common to both the Sordariales and Diaporthales, but is best placed in the Sordariales. Species are inhibitory to other filamentous fungi and yeasts in paired culture, and form soft-rot cavities in balsa and beech wood. SHEARER, C. A. 1989.

Dynamics of a recolonizing population of black bears in the Ouachita Mountains of Oklahoma

Abstract Understanding how populations expand to recolonize former habitats is important to restoration efforts in wildlife management and conservation. Translocation of black bears (Ursus americanus) to Arkansas in the 1950s and 1960s has led to recolonization of former bear range in Oklahoma, with substantial increases in distribution and abundance of the species in Oklahoma over the last 15 years. We studied demographics of black bears in southeastern Oklahoma from May 2001 to November 2002 to provide insight into characteristics of recolonizing populations of large carnivores. We trapped 51 black bears (22 M, 29 F) 77 times and radiocollared 25 female bears. Sex ratios of adults and cubs were skewed toward females, and the age structure was younger than observed in other unharvested populations. Survival of adult females was estimated at 0.9 ±0.1, and fertility was estimated at 0.77 female young/female/year. Density on the study area was estimated at 0.21 bears/km2 and the current finite growth rate (λ) of the study population was estimated to be 1.11/year. Demographic characteristics of the Oklahoma population of black bears were similar to those of other recolonizing populations of large carnivores.
User Affect Elicitation with a Socially Emotional Robot

To effectively communicate with people, social robots must be capable of detecting, interpreting, and responding to human affect during human–robot interactions (HRIs). In order to accurately detect user affect during HRIs, affect elicitation techniques need to be developed to create and train appropriate affect detection models. In this paper, we present such a novel affect elicitation and detection method for social robots in HRIs. Non-verbal emotional behaviors of the social robot were designed to elicit user affect, which was directly measured through electroencephalography (EEG) signals. HRI experiments with both younger and older adults were conducted to evaluate our affect elicitation technique and compare the two types of affect detection models we developed and trained utilizing multilayer perceptron neural networks (NNs) and support vector machines (SVMs). The results showed that; on average, the self-reported valence and arousal were consistent with the intended elicited affect. Furthermore, it was also noted that the EEG data obtained could be used to train affect detection models with the NN models achieving higher classification rates
Role of photosymbiosis and biogeography in the diversification of early Paleogene acarininids (planktonic foraminifera)

Abstract Radiations are commonly believed to be linked to the evolutionary appearance of a novel morphology or ecology. Previous studies have demonstrated a close relationship between the evolutionary appearance of algal photosymbiosis in planktonic foraminifera and evolutionary diversification of Paleogene photosymbiotic clades. For example, the evolution of photosymbiosis was synchronous with the abrupt evolution of four major groups of Paleogene planktonic foraminifera including two clades within the genus Morozovella, as well as the genera Acarinina and Igorina. Our new isotopic and biogeographic data suggest that the acarininids evolved from a photosymbiotic ancestor (which we identify as Praemurica inconstans or early representatives of Praemurica uncinata), but also demonstrate that photosymbiosis did not trigger an immediate species-level radiation in this group. Instead, the acarininids remained a low-diversity taxon restricted to high latitudes for nearly 1.8 million years before radiating ecologically and taxonomically. The eventual radiation of the acarininids is tied to an expansion of their geographic range into the mid and low latitudes. Biogeographic analyses of modern plankton suggest that high-latitude environments may be less conducive to establishing radiations simply because there are fewer niches available to be filled than there are in the tropics. Accordingly, the acarininids may have initially failed to diversify because they started off in environments that presented few opportunities to sustain a large radiation. The high-latitude origin of the acarininids continued to retard their overall diversification until they were able to develop strategies that allowed them to expand into tropical environments and fully exploit their photosymbiotic ecology.
Secondary Angiosarcoma With C-MYC Amplification Following Prophylactic Bilateral Mastectomy and Autologous Breast Reconstruction: Report of a Case and Review of the Literature

In this article, we report a very rare case of secondary angiosarcoma in a young woman with no prior history of breast cancer who had bilateral prophylactic mastectomies with autologous reconstruction due to a strong family history of breast cancer and BRCA1 gene variant of uncertain significance. The surgery was complicated by recurrent fat necrosis requiring several excisions and additional reconstruction followed by the development of localized lymphedema and subsequent angiosarcoma in the reconstructed breast 10 years later. The angiosarcoma was high grade with prominent epithelioid features associated with abundant tumor-infiltrating lymphocytes. Amplification of C-MYC locus 8q21.24 was demonstrated by fluorescence in situ hybridization study. We postulate that chronic trauma from several surgeries including tissue hypoxia and impaired lymphatic drainage may have provided a milieu for angiogenesis and mutagenic transformation. Amplification of C-MYC locus 8q21.24 was most likely a strong oncogenic driver of angiosarcoma. To the best of our knowledge, this is the first report of its kind in the literature.
AGE-SPECIFIC EFFECT OF PARITY ON LITTER SIZE IN THE COMMON VOLE (MICROTUS ARVALIS)

Abstract The “triangular” pattern of reproduction in arvicoline rodents predicts small fecundity early and late in life and high fecundity in the middle. In producing this pattern, the effects of maternal age and parity are typically highly confounded. We present results of a laboratory study designed to disentangle these effects in the common vole (Microtus arvalis) by analyzing variation in sizes of the first 2 litters born to 3 age classes of females subjected to photoperiods of 8 h and 16 h of light. Although the youngest females, paired at 2 weeks of age, decreased size of the 2nd litter in either light environment, the older 2 classes, paired at 3–4 months and 1 year of age, increased their 2nd litters, as predicted by the triangular pattern. This age-specific effect of parity could be explained by differences in the size of 1st litters.
Genetic parameters of growth and carcass quality of lambs at the French progeny-test station berrytest.

INTRODUCTION The Berrytest progeny-test station was created in year 1977. The program was defined in order to simultaneously index for meat qualities, the rams issued from breeding plans, and also estimate the required genetic parameters. First results on genetic parameters were published in 1986 by Bouix et al., based on anonymous rams’ identification, and therefore considered as unrelated. These results come from the period 1989 2001, with known national identification.
