petersson p. & blomqvist k. (2010) Sense of security – searching for its meaning by using stories: a Participatory Action Research study in health and social care in Sweden. International Journal of Older People Nursing 6, 25–32 doi: 10.1111/j.1748‐3743.2010.00211.xAim.  The aim of this study was to make sense of the Swedish concept ‘trygghet’ by using stories from daily life in a Participatory Action Research project.Background.  In Sweden, attempts to implement core values to ensure high quality health and social care for older people are given high priority and concepts such as security and dignity are often used. As concepts are abstract they are difficult to transform into practical work.Design.  One group of six assistant nurses and one group of five Registered Nurses working in a municipality participated in Story Dialogue Method and four older women were interviewed.Result.  ‘Trygghet’ was found to be an internal sense – an intrinsic state based on faith and trust in oneself and others called Sense of security. External factors that strengthened Sense of security were to be part of a community, to recognize and be familiar with things and situations and to use various kinds of aids.Conclusion and relevance to clinical practice.  A prerequisite for the professionals being able to support the care receivers adequately is that they have a sense of security themselves, and that they are allowed to operate in a system that facilitates for the care receivers to maintain trustworthy and reliable relations over time.

ABSTRACT:  The study reports whether or not oregano oil can reduce lipid oxidation and evaluate palatability variations in beef longissimus dorsi and semimembranosus muscles from various age animals (approximately 18 mo; 18 M, 30 to 60 mo; 30 M, and >60 mo; 60 M). Six muscles of each age group were halved and enhanced with a control brine containing no antioxidants (CN) or a brine containing oregano oil (OR), cut into steaks, and stored in modified atmosphere packaging for 0, 4, 7, and 11 d. Each sampling day, surface color (Minolta L*, a*, b*), lipid oxidation (TBARS), cook yield, sensory analysis, and Warner–Bratzler shear force (WBSF) were measured. OR enhancement decreased TBARS values and slowed the rate of decline in a* values (P < 0.05), but had no effect on WBSF, or sensory tenderness and juiciness scores (P > 0.05) compared to CN steaks. OR steaks had less rancidity detection, more off‐flavor, lower overall acceptability in sensory analysis (P < 0.05). This indicated oregano oil can effectively reduce lipid oxidation and extend shelf‐life of meat products, but further investigation would be needed to avoid off‐flavor and acceptability of product quality.Practical Application: Decreases in meat consumption have led the meat industry to become more innovative in product development. Reducing lipid oxidation is a viable method to reduce rancidity, and improving product acceptability. Our research indicated that although oregano oil did reduce lipid oxidation, the adverse effects of flavor were too great, and thus would not be tolerable in fresh meat products at this concentration. However, there is potential to use oregano oil at lower concentrations and in a variety of processed products which could be beneficial to further the use of natural antioxidants.
Improvements in the Quality and Shelf Life of Kimchi by Fermentation with the Induced Bacteriocin‐Producing Strain, Leuconostoc citreum GJ7 as a Starter
Authors: Chang Ji Yoon , Chang Hae Choon 
Published: January 2010

ABSTRACT:  To improve the quality and self‐life of kimchi, the induced bacteriocin‐producing lactic acid bacteria (LAB), Leuconostoc citreum GJ7, was introduced into kimchi fermentation as a starter. The kimchi preparations were incubated at 7 °C for 12 to 15 d, and then stored at −1 °C. Thereafter, changes in their characteristics were monitored for 125 d. When a kimchi starter was introduced into a nonsterile and open kimchi fermentation system, over‐ripening of kimchi was prevented during 125 d of storage. In the starter kimchi, Leuc. citreum GJ7 was the dominant organism, comprising 70% to 90% of the total flora, and no yeasts were detected during the entire storage period. However, in the nonstarter kimchi, the predominant LAB could not be determined and yeasts were detected after 50 d of storage. The viable cell number of the starter kimchi was 2 log CFU/mL higher than in the nonstarter kimchi at 125 d of storage. The texture (firmness) of the starter kimchi at 95 to 125 d of storage was similar to that of the nonstarter kimchi at 20 d of storage. Sensory evaluations of texture, off‐flavor, and carbonated mouthfeel were significantly improved by the starter‐fermentation. The results indicate that the application of the bacteriocin‐enhanced Leuc. citreum GJ7 as a starter culture exerts microbial control, prevents over‐ripening, and extends the shelf life of kimchi.Practical Application: Presently, we have shown that under the optimum fermentation condition the induced bacteriocin‐producing LAB, Leuc. citreum GJ7, can regulate natural kimchi fermentation and has extended dominance within the microbial ecology of kimchi. The result is improved quality and shelf life of kimchi. Moreover, to control the growth of other microorganisms in open‐fermentation and nonsterile conditions, this system may be usefully adapted for other food or environmental control systems.

Published: January 2010

ABSTRACT:  The methanolic extract of Cnidoscolus chayamansa leaves from Mexico was screened for antioxidant and antimutagenic properties by the DPPH, ABTS, iron chelating, and Kado microsuspension assays, respectively. The hypoglycemic effect was also studied. Total phenolic and flavonoid contents as well as HPLC identification and quantification of protocatechuic acid and rutin were also carried out. The C. chayamansa leaves extract contained 71.3 ± 1.7 mg gallic acid equivalent/g extract and 42.6 ± 3.7 mg (+)‐catechin equivalent/g extract of total phenols and flavonoids, respectively. Concentrations of 0.242 ± 0.001 mg/g and 2.00 ± 0.097 mg/g were found for protocatechuic acid and rutine, respectively. The extract was capable of scavenging DPPH and ABTS•+ radicals in a concentration dependent manner. The extract was not toxic to TA100 and TA98 strains at the concentrations tested; moreover, the extract at a concentration of 1000 μg inhibited 24% and 39% the mutagenicity induced by 4‐nitro‐O‐phenylenediamine and sodium azide, respectively. An acute hypoglycemic effect in diabetic rats was observed.Practical Application: C. chayamansa has been proposed as an herbal medicine to treat diabetes; however, the reported results are not conclusive and further studies need to be performed. Despite this fact, chaya leaves can be commercialized as tea in a dried presentation since the dried leaves conserve high polyphenol contents.
Pervasive developmental disorder and early intervention in psychosis services: a survey of care coordinators' experiences
Authors: Del Real Agata , Brabban Alison , Tiffin Paul A. 
Published: January 2010

AbstractAim: To evaluate the experience of care coordinators encountering clients with co‐morbid diagnoses or features of pervasive development disorder (PDD) in an Early Intervention in Psychosis (EIP) service.Methods: A cross‐sectional survey was conducted using a semi‐structured face‐to‐face interview schedule.Results: Thirty‐three care coordinators were interviewed. One‐third of the care coordinators had previously encountered at least one client with a co‐morbid diagnosis of PDD, with the majority feeling confident that they could recognize the features of the syndrome. The estimated reported prevalence of diagnosed PDD in this group was around 4–5%, although social and communication impairments were regularly encountered in clients by at least a quarter of the clinicians interviewed.Conclusions: Social and communication problems are commonly observed by clinicians in this population and some may represent the presence of a co‐morbid PDD. Further efforts should be made to better identify and support this sub‐population of EIP clients.
A 12‐month outcome study of insight and symptom change in first‐episode psychosis

Published: January 2010

AbstractAim: We first aimed to evaluate the progression of insight and psychopathology over the first year of treatment for a psychosis. We hypothesized that improvement in insight would associate with improvement in positive and negative symptoms, and depressive and anxious symptom exacerbation. Secondly, in an exploratory analysis, we aimed to identify quantitatively distinct insight trajectory groups, and to describe the impact of psychopathology over time on the different trajectory groups.Methods: One‐hundred and sixty‐five patients were administered a comprehensive clinical evaluation, and insight was rated on the Scale for Assessment for Unawareness of Mental Disorder, item 1 (awareness of mental disorder), at admission and after 1, 2, 3, 6, 9 and 12 months.Results: In a generalized estimating equation (GEE) model of change, insight improved concurrently with positive, negative and anxious symptoms between baseline and month 1 in the entire cohort. Latent group‐based trajectory analysis revealed five insight groups: good, increasing, decreasing, moderate poor and very poor. GEE modelling revealed that the very poor and moderate poor insight groups displayed greater overall negative symptoms than patients with good and increasing insight trajectories. The good insight group showed significantly greater overall depressive symptoms than the diminished and very poor insight groups.Conclusions: The results suggest that specific longitudinal insight trajectories were driving the observed associations between insight and negative and depressive symptoms in the entire first‐episode psychosis cohort. Persistently poor insight may be an important factor in negative symptom maintenance. Good or increasing course of insight may be early clinical indicators of a liability to depression.

Satellite Rainfall Estimates Over South America – Possible Applicability to the Water Management of Large Watersheds. Journal of the American Water Resources Association (JAWRA) 46(2):344‐360. DOI: 10.1111/j.1752‐1688.2009.00406.xAbstract:  This work analyzes high‐resolution precipitation data from satellite‐derived rainfall estimates over South America, especially over the Amazon Basin. The goal is to examine whether satellite‐derived precipitation estimates can be used in hydrology and in the management of larger watersheds of South America. High spatial‐temporal resolution precipitation estimates obtained with the CMORPH method serve this purpose while providing an additional hydrometeorological perspective on the convective regime over South America and its predictability. CMORPH rainfall estimates at 8‐km spatial resolution for 2003 and 2004 were compared with available rain gauge measurements at daily, monthly, and yearly accumulation time scales. The results show the correlation between satellite‐derived and gauge‐measured precipitation increases with accumulation period from daily to monthly, especially during the rainy season. Time‐longitude diagrams of CMORPH hourly rainfall show the genesis, strength, longevity, and phase speed of convective systems. Hourly rainfall analyses indicate that convection over the Amazon region is often more organized than previously thought, thus inferring that basin scale predictions of rainfall for hydrological and water management purposes have the potential to become more skillful. Flow estimates based on CMORPH and the rain gauge network are compared to long‐term observed average flow. The results suggest this satellite‐based rainfall estimation technique has considerable utility. Other statistics for monthly accumulations also suggest CMORPH can be an important source of rainfall information at smaller spatial scales where in situ observations are lacking.

Journal of the American Water Resources Association (JAWRA) 46(2):367‐384. DOI: 10.1111/j.1752‐1688.2009.00407.xAbstract:  Wetlands provide many critical functions in urban ecosystems, including habitat for wetland‐dependent fauna and enhancement of water quality. Interest in restoring or creating wetlands to enhance these functions is increasing due to the scale and extent of wetland loss and water quality problems associated with urbanization. One of the most pressing questions associated with urban wetland restoration is the extent to which urban wetlands tend to concentrate contaminants, and if so, whether an associated risk to wildlife exists. The goal of this study was to better understand these potential risks, and the associated tradeoffs with using wetlands to treat urban runoff. Sediment toxicity, contaminant chemistry, and macroinvertebrate (MI) community metrics were measured in 21 southern California wetlands that receive urban runoff as their primary water source. MI organisms in 18 of the 21 urban wetlands examined were considered to be at risk due to sediment contaminant concentrations and toxicity. Most of the sites were either toxic to the amphipod Hyalella azteca, exceeded a sediment quality guideline, or both. Sediment chemistry and toxicity identification evaluation studies suggest that pyrethroid pesticides may have been responsible for much of the toxicity documented in this study. The mean Probable Effects Concentration quotient (an index of degree of sediment contamination) was found to negatively correlate with MI diversity in these wetlands suggesting that toxicity was affecting organisms at the base of the food chain in these wetlands.

Smith, Monica Lipscomb, Weiqi Zhou, Mary Cadenasso, Morgan Grove, and Lawrence E. Band, 2010. Evaluation of the National Land Cover Database for Hydrologic Applications in Urban and Suburban Baltimore, Maryland. Journal of the American Water Resources Association (JAWRA) 46(2):429‐442. DOI: 10.1111/j.1752‐1688.2009.00412.xAbstract:  We compared the National Land Cover Database (NLCD) 2001 land cover, impervious, and canopy data products to land cover data derived from 0.6‐m resolution three‐band digital imagery and ancillary data. We conducted this comparison at the 1 km2, 9 km2, and gauged watershed scales within the Baltimore Ecosystem Study to determine the usefulness and limitations of the NLCD in heterogeneous urban to exurban environments for the determination of land‐cover information for hydrological applications. Although the NLCD canopy and impervious data are significantly correlated with the high‐resolution land‐cover dataset, both layers exhibit bias at <10 and >70% cover. The ratio of total impervious area and connected impervious area differs along the range of percent imperviousness – at low percent imperviousness, the NLCD is a better predictor of pavement alone, whereas at higher percent imperviousness, buildings and pavement together more resemble NLCD impervious estimates. The land‐cover composition and range for each NLCD urban land category (developed open space, low‐intensity, medium‐intensity, and high‐intensity developed) is more variable in areas of low‐intensity development. Fine‐vegetation land‐cover/lawn area is incorporated in a large number of land use categories with no ability to extract this land cover from the NLCD. These findings reveal that the NLCD may yield important biases in urban, suburban, and exurban hydrologic analyses where land cover is characterized by fine‐scale spatial heterogeneity.
Future U.S. Water Consumption: The Role of Energy Production1

Elcock, Deborah, 2010. Future U.S. Water Consumption: The Role of Energy Production. Journal of the American Water Resources Association (JAWRA) 46(3):447‐460. DOI: 10.1111/j.1752‐1688.2009.00413.xAbstract:  This study investigates how meeting domestic energy production targets for both fossil and renewable fuels may affect future water demand. It combines projections of energy production developed by the U.S. Department of Energy with estimates of water consumption on a per‐unit basis (water‐consumption coefficients) for coal, oil, gas, and biofuels production, to estimate and compare the domestic freshwater consumed. Although total domestic freshwater consumption is expected to increase by nearly 7% between 2005 and 2030, water consumed for energy production is expected to increase by nearly 70%, and water consumed for biofuels (biodiesel and ethanol) production is expected to increase by almost 250%. By 2030, water consumed in the production of biofuels is projected to account for nearly half of the total amount of water consumed in the production of all energy fuels. Most of this is for irrigation, and the West North Central Region is projected to consume most of this water in 2030. These findings identify an important potential future conflict between renewable energy production and water availability that warrants further investigation and action to ensure that future domestic energy demand can be met in an economically efficient and environmentally sustainable manner.
A revised late-Quaternary vegetation history of the unglaciated southwestern Yukon Territory, Canada, from Antifreeze and Eikland ponds
Authors: Vermaire Jesse C. , Cwynar Les C. 
Published: January 2010

Antifreeze Pond was thought to contain the oldest record of continuous environmental change in the southwestern Yukon. We have revised the original interpretation of the vegetation history of Antifreeze Pond and this region based on new pollen, stomate, and macrofossil analysis, along with 38 new accelerator mass spectrometry (AMS) 14C dates from Antifreeze Pond and nearby Eikland Pond. Although the overall pattern of vegetation change is similar to the previously published Antifreeze Pond record, our new analysis indicates that the timing of the major vegetation shifts is substantially different, particularly during the late-glacial and early Holocene periods (from ∼17 000 – 9000 cal years BP). The original Antifreeze Pond record was thought to span a mid-Wisconsinan interstadial (>30 000 cal years BP) and the full-glacial period. Our results, however, indicate that the material of mid-Wisconsinan age was likely deposited by slumping around the pond making interpretation of the paleoenvironment difficult. Furthermore, our AMS 14C dates show that what was thought to be a full-glacial vegetation record is actually the vegetation history of the late-glacial period (ca. 17 000 – 11 000 cal years BP), which was a time of rapid sediment deposition into the ponds. The Eikland Pond record has an early Holocene Populus rise between ca. 11 000 – 8000 cal years BP that is not present in either the new or original Antifreeze Pond records. This new interpretation of the vegetation history should aid comparisons to other regional paleoenvironmental records.

Published: January 2010

Ballast water is recognized globally as a major vector of aquatic nonindigenous species (NIS) introductions; domestic ballast water transfers, however, have generally been considered low risk in North America. We characterize ballast operations of domestic ships in the Great Lakes – St. Lawrence River system (Lakers) during 2005–2007 to examine the risk of primary and secondary introductions associated with ballast water transfers over short distances. Results indicate that Lakers transported at least 68 million tonnes of ballast water annually. Approximately 71% of ballast water transfers were interregional, with net movement being from lower to upper lakes. A small proportion of ballast water discharged in the Great Lakes (<1%) originated from ports in the St. Lawrence River that may serve as sources for new NIS. These results indicate that domestic ballast water transfers may contribute to NIS introductions and are likely the most important ballast-mediated pathway of secondary spread within the Great Lakes. Future efforts to reduce invasion impacts should consider both primary and secondary introduction mechanisms.
Intra- and intergenomic chromosome pairings revealed by dual-color GISH in trigenomic hybrids ofBrassica junceaandB. carinatawithB. maurorum

Published: January 2010

From dual-color genomic in situ hybridization (GISH) analysis of three trigenomic hybrids, Brassica maurorum (MM, 2n = 16) × B. juncea (AABB, 2n = 36) (M.AB), B. maurorum × B. carinata (BBCC, 2n = 34) (M.BC), and B. carinata × B. maurorum (BC.M), the three genomes of each hybrid were distinguished and autosyndesis and allosyndesis were evaluated. In M.AB, up to two autosyndetic bivalents occurred among the chromosomes of each genome; a maximum of three allosyndetic bivalents appeared between A-B, A-M, and B-M genomes. The similar pairings in M.BC and BC.M suggested that the cytoplasm of B. maurorum or B. carinata had no obvious effect on chromosome pairing. In M.BC and BC.M, a maximum of one autosyndetic bivalent was found for B and M genomes, but two were found for the C genome; from 0 to 2 allosyndetic bivalents were observed between B-C, B-M, and C-M genomes. The B-M allosyndesis frequency was higher than the A-M or C-M allosyndesis frequency in these hybrids, revealing the closer relationship of B and M genomes. The allosyndesis frequency was higher than the autosyndesis frequency among A, B, and C genomes in these combinations, suggesting that intergenomic homoeology was higher than intragenomic homoeology. The implications for genome evolution and crop breeding are discussed.
