[source] SHELF LIFE OF FRESH NOODLES AS AFFECTED BY THE FOOD GRADE MONOLAURIN MICROEMULSION SYSTEMJOURNAL OF FOOD PROCESS ENGINEERING, Issue 5 2008XIAOWEI FU ABSTRACT Food grade monolaurin (the glycerol monoester of lauric acid) microemulsions (MMEs) based on multicomponent mixtures and the effects of MMEs on the shelf life of fresh noodles were studied. A microemulsion system consisting of monolaurin (M), surfactants (Tween 20 and Tween 80, Wenzhou Qingming Chemical Engineering Company, Wenzhou, Zhejiang, China ) and cosurfactant (pentanol and dodecanol) dispersed in distilled water was used. The influence of surfactants on the phase behavior was studied in this article. Subsequently, two MMEs with large oil in water regions have demonstrated the enhanced antimicrobial activities against Bacillus subtilis, Escherichia coli, Aspergillus niger and Penicillium digitatum, compared to monolaurin (M) alone. In addition, the shelf life of fresh noodles prepared with monolaurin (M) alone was about 4 days, whereas MMEs extended shelf life by 10 days at least when stored at 37C. PRACTICAL APPLICATIONS The effect of monolaurin microemulsion (MME) as antimicrobial agents in foods, especially those neutral foods such as noodles, is obvious, and MME has demonstrated a much longer shelf life of fresh noodles than M alone. In addition, for those neutral foods other than fresh noodles, the application of MMEs can also be studied. [source] EXTENDING SHELF LIFE OF FRESH-CUT PERSIMMON BY HONEY SOLUTION DIPSJOURNAL OF FOOD PROCESSING AND PRESERVATION, Issue 1 2010MUHARREM ERGUN ABSTRACT Ripe persimmon fruit (Diospyros kaki L) cv. "Hachiya" were diced, then treated with 10,20% w/v diluted honey solution or water as the control, followed by cold storage at 4C until loss of acceptable quality. The persimmon cubes were subject to assessments during the storage of organoleptic and visual quality, softness and exuding juice, soluble solids content (SSC), and absorbance at 436, 440, 675 and 760 nm, respectively. Honey treatments prevented off-aroma development and delayed jelling. Softness and exuding juice of the fresh-cut persimmon cubes increased with time, with the increase in both parameters being significantly suppressed by honey solution dips. Changes in SSC, pH and the absorbance at 436, 440, 675 and 760 nm, respectively, during storage were minor and there was little effect of the honey treatments on these parameters. Overall, the shelf life of fresh-cut persimmon cubes was extended by honey solution dips, which delayed off-aroma development, firmness loss and jelling. PRACTICAL APPLICATIONS New products and changing trends make today's food marketplace alive, and fresh-cut fruits and vegetables seem to be on top of list of these products. Although fresh-cut produce has been on the market for a long time, preserving their quality attributes has not been completely successful especially in the case of fruit. This study focuses on a new alternative fresh-cut produce, fresh-cut persimmon, with adapting a potentially safe organic method, use of honey dips. The present study demonstrated that honey solution dip treatments could preserve the fresh-like quality of typical flavor or aroma of persimmon fruit by causing no changes in aroma and taste attributes and extending shelf life. Therefore, honey dip treatment may be used, depending on commodity, to preserve and extend shelf life of fresh-cut produce in fresh-cut processing industry. [source] THE EFFECTS OF HOT SMOKING ON THE CHEMICAL COMPOSITION AND SHELF LIFE OF MEDITERRANEAN MUSSEL (MYTILUS GALLOPROVINCIALIS L. 1819) UNDER CHILLED STORAGEJOURNAL OF FOOD PROCESSING AND PRESERVATION, Issue 6 2008HÜLYA TURAN ABSTRACT In this study, effects of boiling and hot smoking on proximate composition and shelf life of mussels stored at 4 ± 1C were investigated. Dry matter, crude protein, crude fat and crude ash levels were determined as 13.94, 10.30, 1.14 and 0.95% in fresh mussels 20.75, 13.83, 2.11, 0.77% after boiling and 39.57, 22.22, 10.04%, 6.02% after hot smoking, respectively. Trimethylamine nitrogen values in fresh, boiled and hot smoked mussels were determined as 1.13, 1.01 and 1.07 mg/100 g, respectively, and increased to 24.35 mg/100 g at 18th day of the storage period. pH value in hot smoked mussels ranged between 4.85 and 4.51 during the chilled storage. According to the results, mussels smoked by hot smoking and stored at refrigerator temperature (4 ± 1C) for 12 days can be consumed. PRACTICAL APPLICATIONS In many countries, smoking is used to obtain products that are popular for their texture and flavor. Mussels, scallops and oysters are some of the important mollusk species that are smoked and eaten in different parts of the world. In this research, the effects of hot smoking process (for 30 min at 82C) on proximate composition and shelf life of Mediterranean mussel stored at 4C was investigated. [source] THE EFFECT OF MODIFIED ATMOSPHERE PACKAGING ON THE QUALITY AND SHELF LIFE OF FRANKFURTER TYPE-SAUSAGESJOURNAL OF FOOD QUALITY, Issue 2010NALAN GOKOGLU ABSTRACT The effects of modified atmosphere packaging on the quality and shelf life of frankfurter-type sausages, prepared exclusively from beef meat, were investigated. Sausages were packed under varying modified atmosphere conditions (30% CO2/70% N2; 70% CO2/30% N2; 100% CO2; 80% CO2/20% O2) and vacuum, and stored at 4C for 28 days. Lower pH values were observed in the samples packed under modified atmospheres compared to vacuum. Inhibition effect of carbon dioxide concentration on the oxidation was seen. Carbon dioxide caused microbial inhibition. The lowest total viable count was found in the samples packed under 100% CO2. It was concluded that modified atmosphere packaging had significant effect on the quality and shelf life of frankfurter-type sausages compared to vacuum packaging. The most suitable atmosphere among the tested atmospheres was that with 70% CO2, 30% N2 atmosphere. The shelf life of sausages under this atmosphere was 28 days. PRACTICAL APPLICATIONS Meat and meat products are susceptible to spoilage. Several preservation techniques are used to extend their shelf life. Packaging of fresh meat is a common application to protect its quality. Modified atmosphere packaging (MAP) means to replace the air in a package of food with some different mixture of gases. The success in MAP is to choose the suitable gas combination, packaging system, package application and the package material. Proper gas combination to keep meat quality should be provided. Several studies have been performed to extent shelf life of pork sausages and local-type sausages using modified atmosphere packaging technique. However there is no data on beef sausages. The results of this research will form the basis for further studies and also will be beneficial for industry. [source] IMPROVING THE QUALITY AND SHELF LIFE OF TURKISH ALMOND PASTEJOURNAL OF FOOD QUALITY, Issue 4 2008ESRA CAPANOGLU ABSTRACT Almond paste is an economically valuable product produced from almonds, sugar and a small amount of water. Oxidative rancidity and oil separation are the major problems that are encountered in the paste products affecting the shelf life. Another problem appears to be drying on the surface of the product resulting in poor consumer acceptability. In this study, the formulation of product was altered by adding a commercial stabilizer, antioxidant mixture and maltose syrup to prevent undesirable quality changes during storage at 4C and 30C. Peroxide value, free fatty acid and Rancimat analysis showed that the addition of antioxidant mixture prevented oxidation effectively and improved sensory scores significantly (P , 0.05). Although stabilizer addition had a detrimental effect on the textural properties, samples that have maltose had high sensory scores. The results showed that incorporation of maltose syrup and antioxidant may improve the texture and shelf life of almond paste. PRACTICAL APPLICATIONS The available literature on almond paste is mainly focused on the microbiological quality of the product and the prevention of spoilage reactions by modifying packaging materials. However, there is no report on the optimization of the composition to extend the shelf life of almond paste. Turkish almond paste, a healthy and expensive dessert, is a specialty product that is manufactured by using traditional grinding equipment. However, the limited shelf life of this product decreases its export potential resulting in economical losses. Therefore, improved shelf life and quality of the product is of importance from the economical point of view. In our study, we aimed to improve the quality and shelf life of Turkish almond paste by modifying its formulation in order to minimize the undesirable changes that occur during storage. [source] ASSESSMENT OF A WASH TREATMENT WITH WARM CHLORINATED WATER TO EXTEND THE SHELF,LIFE OF READY,TO,USE LETTUCEJOURNAL OF FOOD QUALITY, Issue 3 2003J.A. ODUMERU There was a significant difference in psychrotrophic counts (P<0.0001) of warm chlorine (100 ppm) washed lettuce at 47 ± 2C for 30 s, 60 s, and 180 s exposure from days 1 to 10 of storage at 4C compared with cold chlorine (100 ppm) washed lettuce at 4 ± 1C for 30 s. There were no significant differences in psychrotrophic counts between wash treatments of 30 s and 60 s during 17 days storage (P < 0.05). The EN detected initially high levels of volatiles in this group compared with cold treatment. Lettuce samples treated with cold or warm chlorine wash water showed no differences in the presence/absence or levels of Listeria monocytogenes. The warm chlorine washed lettuce samples were rated acceptable upon sensory evaluation up to day 14. [source] STRATEGIES FOR PROLONGING THE SHELF LIFE OF MINCED BEEF PATTIESJOURNAL OF FOOD SAFETY, Issue 1 2009MATTEO ALESSANDRO DEL NOBILE ABSTRACT The study of different strategies for prolonging the shelf life of fresh minced beef patties was addressed in this work. Fresh minced beef was supplemented with thymol (THY) at levels of 250, 500 and 750 mg per kg of ground beef. Treated samples were packed using a high barrier film and stored in refrigerated conditions (4C) under ordinary atmosphere packaging and modified atmosphere packaging (MAP) conditions for 16 days. The microbiological quality decay kinetic was determined by monitoring the following microorganisms: Enterobacteriaceae, Pseudomonas spp., lactic acid bacteria, Brochothrix thermosphacta, coliforms and total psychrotrophic viable count. Results show that THY, working alone, was effective on coliforms and Enterobacteriaceae, whereas it does not seem to inhibit to a great extent the growth of the other microbial populations. On the other hand, an increased amount of THY, under MAP conditions, had better effects on the product quality, with a consequent prolongation of the shelf life. PRACTICAL APPLICATIONS Great interest is developing in food bio-preservation, because of the ever-increasing needs to protect consumers' health and to valorize the naturalness and safety of food products. However, very few works have been carried out on the applications of bio-preservatives to extend the shelf life of fresh meat products. This study, therefore, was mainly initiated to evaluate the possibility of extending the shelf life of packed fresh meat patties by a combination of thymol (THY) to other extrinsic factors such as storage temperatures and modified atmosphere during packaging. Interesting results were obtained suggesting that THY can perform an efficient synergy with modified atmosphere conditions and could be advantageously utilized by the meat industry.

[source] QUALITY OF LIFE OF GREEK PATIENTS WITH END STAGE RENAL DISEASE UNDERGOING HAEMODIALYSISJOURNAL OF RENAL CARE, Issue 3 2010Maria Kastrouni RN SUMMARY An evaluation of the quality of life of patients with end stage kidney disease undergoing haemodialysis in the Greek population was conducted to understand whether this quality could be improved. Comparisons were made with a similar study conducted in United States in regards to the effects of kidney disease in daily life, burden of kidney disease, work status, cognitive function, quality of social interaction, sexual function, social support, physical functioning, role physical on daily routine, pain, general health perceptions, role emotional, emotional well being, social function and energy/fatigue. Any differences are discussed and analysed. Sexual problems were found to be more prominent in this study, but the emotional status has greater influence in quality of life in the US study. The results were more positive in Greece with respect to dialysis staff encouragement, patient satisfaction, as well as acceptance and the understanding of illness. The results from our study reflect the differences of the health care systems in various countries as well as population-related beliefs and values. [source] CURRENT-STATUS SURVIVAL ANALYSIS METHODOLOGY APPLIED TO ESTIMATING SENSORY SHELF LIFE OF READY-TO-EAT LETTUCE (LACTUCA SATIVA)JOURNAL OF SENSORY STUDIES, Issue 2 2008MABEL ARANEDA ABSTRACT The objective of the present work was to develop a method for predicting sensory shelf life for situations in which each consumer evaluates only one sample corresponding to one storage time. This type of data is known as current-status data in survival analysis statistics. The methodology was applied to estimate the sensory shelf life of ready-to-eat lettuce (Lactuca sativa var. capitata cv."Alpha"). For each of six storage times, 50,52 consumers answered yes or no to whether they would normally consume the presented sample. The results were satisfactory, showing that the methodology can be applied when necessary. The Weibull model was found adequate to model the data. Estimated shelf lives ± 95% confidence intervals were 11.3 ± 1.2 days and 15.5 ± 0.9 days for a 25% and a 50% consumer rejection probability, respectively. PRACTICAL APPLICATIONS When considering shelf-life evaluations by consumers, the first idea is to have each consumer evaluate six or seven samples with different storage times in a single session. To do this, a reverse storage design is necessary, and in the case of a product such as lettuce, it would lead to different batches being confused with storage times. The methodology proposed in this article avoids this problem by having each consumer evaluate a single sample. Another issue with consumers tasting several samples in a single session is how representative this situation is of real consumption. The present methodology allows for a consumer to take home, e.g., a bottle of beer with an established storage time, and later collecting the information as to whether they found the beer acceptable or not. This is a situation much closer to real consumption.

[source] A PUNIC JUG FROM THE MUSEUM OF ST AGATHA, RABAT, MALTA: A GLANCE AT PUNIC EVERYDAY LIFEOXFORD JOURNAL OF ARCHAEOLOGY, Issue 2 2005ANNELIESE HÜBNER Summary. The assumption of a long-term overlapping or co-existence of cultures there has been confirmed by a very small inscription which came to my attention during research for my doctoral thesis ,From Expansion to Isolation. A study on the development of the Phoenician,Punic culture on the islands of Malta and Gozo'. Pottery chronology and the use of epigraphy and palaeography illustrate that at a time when Malta and Gozo had long been under Roman rule, the harmonious co-existence of the Punic, Greek and Roman cultures was manifested in one vessel and in one inscription. The Maltese archipelago assumes a special status owing to its isolation. There is hardly any comparable area of 246 sq km in which the phenomenon of cultural overlapping and cultural parallels can be found in such density. [source] HOW DID LIFE BECOME SO DIVERSE?PALAEONTOLOGY, Issue 1 2007THE DYNAMICS OF DIVERSIFICATION ACCORDING TO THE FOSSIL RECORD AND MOLECULAR PHYLOGENETICS Abstract:, The long-term diversification of life probably cannot be modelled as a simple equilibrial process: the time scales are too long, the potential for exploring new ecospace is too large and it is unlikely that ecological controls can act at global scales. The sum of many clade expansions and reductions, each of which happens according to its own dynamic, probably approximates more a damped exponential curve when translated into a global-scale species diversification curve. Unfortunately, it is not possible to plot such a meaningful global-scale species diversification curve through time, but curves at higher taxonomic levels have been produced. These curves are subject to the vagaries of the fossil record, but it is unlikely that the sources of error entirely overwhelm the biological signal. Clades radiate when the external and internal conditions are right: a new territory or ecospace becomes available, and the lineage has acquired a number of characters that open up a new diet or mode of life. Modern high levels of diversity in certain speciose clades may depend on such ancient opportunities taken. Dramatic climatic changes through the Quaternary must have driven extinctions and originations, but many species responded simply by moving to more favourable locations. Ecological communities appear to be no more than merely chance associations of species, but there may be real interactions among species. Ironically, high species diversity may lead to more speciation, not, as had been assumed, less: more species create more opportunities and selective pressures for other species to respond to, rather than capping diversity at a fixed equilibrium level. Studies from the scale of modern ecosystems to global long-term patterns in the fossil record support a model for the exponential diversification of life, and one explanation for a pattern of exponential diversification is that as diversity increases, new forms become ever more refinements of existing forms. In a sense the world becomes increasingly divided into finer niche space. Organisms have a propensity to speciate freely, species richness within ecosystems appears to generate opportunities for more speciation, clades show all kinds of patterns from sluggish speciation rates and constant diversity through time to apparently explosive speciation, and there is no evidence that rapidly speciating clades have reached a limit, nor that they are driving other clades to extinction. A corollary of this view is that current biodiversity must be higher than it has ever been. Limits to infinite growth are clearly local, regional, and global turnover and extinction events, when climate change and physical catastrophes knock out species and whole clades, and push the rising exponential curve down a notch or two. [source] WEIGHTED LOTTERIES IN LIFE AND DEATH CASESRATIO, Issue 1 2007Iwao Hirose Faced with a choice between saving one stranger and saving a group of strangers, some people endorse weighted lotteries, which give a strictly greater chance of being saved to the group of strangers than the single stranger. In this paper I attempt to criticize this view. I first consider a particular version of the weighted lotteries, Frances Kamm's procedure of proportional chances, and point out two implausible implications of her proposal. Then, I consider weighted lotteries in general, and claim (1) that the correct thing to distribute is not the chance of being saved but the good of being saved, (2) that assigning some chance to the single stranger is not the only way to give a positive (and equal) respect to the people concerned, and (3) that the weighted lottery appears to be deceptive since it would show the respect to the single stranger in a negligible way. [source] FORBIDDEN WAYS OF LIFETHE PHILOSOPHICAL QUARTERLY, Issue 233 2008Ben Colburn I examine an objection against autonomy-minded liberalism sometimes made by philosophers such as John Rawls and William Galston, that it rules out ways of life which do not themselves value freedom or autonomy. This objection is incorrect, because one need not value autonomy in order to live an autonomous life. Hence autonomy-minded liberalism need not rule out such ways of life. I suggest a modified objection which does work, namely that autonomy-minded liberalism must rule out ways of life that could not develop under an autonomy-promoting education. I conclude by suggesting some reasons why autonomy-minded liberals should bite the bullet and accept this. [source] LIFE IN THE 813: ONE DAY A MIGRANT STUDENT, THE NEXT A GANGSTERANNALS OF ANTHROPOLOGICAL PRACTICE, Issue 1 2009Alayne Unterberger In this article, I summarize, through the use of two case studies, the anthropological contributions when working with farmworker,migrant youth who have become "gang-involved." The Florida Institute for Community Studies (FICS) worked with a total of 65 youth and their families in a federal antigang initiative, with one session being held in a Presbyterian-based farmworker mission and another at a middle school. Both groups of youth live in rural Hillsborough County, Florida, with a lack of afterschool or other prosocial opportunities outside of school. I share my personal experiences and reflections on how I got involved in working with gangs, which had not been a priority for me in the past. One area of concern was our finding that youth were recruited into gangs and risky behaviors through friendship and familial networks. The school-based youth did not fare as well as the mission-based group, principally because of labeling by the school and the lack of autonomy of youth in a school setting to take ownership of the program. I provide recommendations for anthropologists working with youth who live "la vida loca" or the crazy life. [source] LIVING A DISTRIBUTED LIFE: MULTILOCALITY AND WORKING AT A DISTANCEANNALS OF ANTHROPOLOGICAL PRACTICE, Issue 1 2008Brigitte Jordan In the last few years, new collaboration and communication technologies have led to a deterritorialization of work, allowing for the rise of new work- and lifestyles. In this article, I use my own transition from the life of a corporate researcher to that of a multilocal mobile consultant for tracking some of the patterns I see in a changing cultural and economic environment where work and workers are no longer tied to a specific place of work. My main interest lies in identifying some of the behavioral shifts that are happening as people are caught up in and attempt to deal with this changing cultural landscape. Writing as a knowledge worker who now moves regularly from a work,home place in the Silicon Valley of California to another in the tropical lowlands of Costa Rica, I use my personal transition as a lens through which to trace new, emergent patterns of behavior, of values, and of social conventions. I assess the stresses and joys, the upsides and downsides, the challenges and rewards of this work- and lifestyle and identify strategies for making such a life successful and rewarding. Throughout, there emerges an awareness of the ways in which the personal patterns described reflect wider trends and cumulatively illustrate global transformation of workscapes and lifescapes. These types of local patterns in fact constitute the on-the-ground material reality of global processes that initiate and sustain widespread culture change and emergent societal transformations.

The debate around the likelihood of humans encountering extraterrestrial life is based in the broad context of cosmic evolution, which encompasses astronomical, biological and socio-cultural evolution. In this depiction of cosmic evolution from the US National Aeronautics Space Administration (NASA), the upper left portion shows the formation of stars, the production of heavy elements and the formation of planetary systems, including our own. On the lower left-hand side prebiotic molecules, RNA and DNA are formed within the first billion years on the primitive Earth. The centre shows the origin and evolution of life leading to increasing complexity, culminating with intelligence, culture, and the astronomers who contemplate the universe on the upper right. The image was created by David DesMarais, Thomas Scattergood and Linda Jahnke at NASA's Ames Research Center in 1986, and reissued in 1997. In this issue Steven J. Dick, Chief Historian at NASA, recounts the history of anthropological involvement in the search for extraterrestrial intelligence, and discusses SETI's broader relevance to anthropology. Anthropologists are uniquely qualified by knowledge and training to contribute to SETI, since central concerns when and if contact is made will include socio-cultural difference and cross-cultural communication. In turn the extraterrestrial perspective has much to offer anthropology, both in expanding its boundaries, its insights and its tools, and in casting a fresh light on cultures on Earth. Valerie Olson, in her review of the session dedicated to SETI at the 2005 American Anthropological Association Annual Meeting, argues that the SETI vision of a terrestrial/extraterrestrial dichotomy between human and alien ,others' brings older and more recent anthropological ideas into a new juxtaposition, and that SETI has potential for stimulating the anthropological imagination. [source] INTEGRATION OF PROSPECTIVE QUALITY OF LIFE AND NUTRITIONAL ASSESSMENT AS ROUTINE COMPONENTS OF MULTIDISCIPLINARY CARE OF PATIENTS WITH HEAD AND NECK CANCERANZ JOURNAL OF SURGERY, Issue 1-2 2008Justine Oates Background: Quality of life (QOL) and nutritional assessment of patients with head and neck cancer can provide additional information about the effects of treatment beyond the standard measures of disease control and survival. Integrating a prospective evaluation program into a multidisciplinary service may ensure that a more holistic model of care is developed. Methods: Prospective evaluation of QOL and nutrition before and after treatment for head and neck cancer was implemented in 2001. All patients enrolled in the program were treated with curative intent. Patients completed the European Organisation for Research and Treatment of Cancer Core QOL Questionnaire and Head and Neck Specific Module before treatment and at 3, 6 and 12 months after completion of therapy. In conjunction, patients underwent nutritional assessment by body mass index, biochemical parameters and the patient-generated subjective global assessment tool. Results: Among 288 patients who consented to participate in this study, 134 patients completed the QOL assessment criteria and were eligible for evaluation. Examples of QOL and nutritional data for patients with cancers of the oral cavity, oropharynx, nasopharynx, larynx, hypopharynx, parotid gland and paranasal sinus, and also unknown primary cancers are given. Implementation of this prospective assessment program required appropriate resources and was hampered by time constraints, logistics with blood tests and patient compliance. Conclusions: Despite difficulties with implementation, the information concerning QOL and nutritional status obtained in this study provided an appreciation of the long-term functional effects of treatment for head and neck cancer. Prospective QOL assessment and nutritional evaluation should become integral components of the care of patients with cancers of the head and neck. [source] PANCREATICODUODENECTOMY WITH PANCREATICOGASTROSTOMY: ASSESSMENT OF PATIENTS' NUTRITIONAL STATUS, QUALITY OF LIFE AND PANCREATIC EXOCRINE FUNCTIONANZ JOURNAL OF SURGERY, Issue 3 2000Hock Soo Ong Background: The changes in digestive function of patients with pancreaticoduodenectomy (PD) and pancreaticogastrostomy reconstruction have not been well-documented. The present study sought to assess the nutritional status, quality of life and pancreatic exocrine function in this group of patients. Methods: The study group consisted of 11 PD with pancreaticogastrostomy patients. The control group consisted of 11 consecutive patients who had subtotal gastrectomy (SG) for distal stomach tumours. Results: The median ages for the PD and SG groups were 57 and 59 years, respectively. The median intervals between surgery to assessment were 68 and 60 weeks, respectively. The PD group attained a mean of 92.7% of their pre-surgery weight compared to 91.3% in the SG group. Both groups had a comparable gastrointestinal quality of life index and Visick scale scores. Exocrine insufficiency using the faecal chymotrypsin test was present in 36% of patients with PD. None of the patients in the SG group had exocrine insufficiency. Conclusion: Pancreaticoduodenectomy patients had a significant occurrence of pancreatic exocrine insufficiency compared to the SG group. But patients with PD and pancreaticogastrostomy reconstruction maintained a nutritional status and quality of life similar to those with curative SG for stomach malignancy. Apart from exocrine insufficiency, the concomitant gastrectomy in the PD group is an important factor responsible for their inability to gain weight. [source] Interaction between macroinvertebrates, discharge and physical habitat in upland riversAQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue S1 2010Michael J. Dunbar Abstract 1.There is a need to relate changing river flows to ecological response, particularly using methods which do not require extensive new data for water bodies without historical data. This paper describes how local-scale habitat features and changing discharge appear to influence a macroinvertebrate-based biotic index. 2.The study used 87 time-series of river biomonitoring data from upland, wadeable streams with quasi-natural flow regimes across England and Wales. Twenty-seven of the sites were matched to a nearby flow gauging station, and historical, natural flows using a generalized rainfall-runoff model were synthesized for 60 sites. All sites were matched to a River Habitat Survey (RHS) within 1,km. 3.The data were analysed using multilevel linear regression, combining sample- and site-level characteristics as predictors. Common responses were assessed across sites, using the biotic index LIFE (Lotic Invertebrate index for Flow Evaluation), an average of abundance-weighted Flow Groups which indicate the relative preference among taxa for higher velocities with gravel/cobble substrates or slow velocities with finer substrates. The aim was to understand the influence of physical habitat on macroinvertebrate response to antecedent high and low flow magnitude. 4.There was a positive relationship between LIFE score calculated from spring and autumn samples and antecedent high (Q10) and low flows (Q95). The relationship between summer Q10 and autumn LIFE score was steeper than the relationship between winter Q10 and spring LIFE score. Bed and bank resectioning reduced overall LIFE and increased the steepness of the response of LIFE to low (Q95) flow. 5.The models derived may be used to guide environmental flow allocations and to quantify the relative influence of flow and physical habitat change on macroinvertebrate responses. The interaction between resectioning and low flow has particular implications for the conservation of macroinvertebrate taxa with requirements for faster flowing water. Copyright © 2010 John Wiley & Sons, Ltd. [source] THE SOCIAL LIFE OF THE BYZANTINE GIFT: THE ROYAL CROWN OF HUNGARY RE-INVENTEDART HISTORY, Issue 5 2008CECILY J. HILSDALE Inspired by what anthropologists have called the social life of things, this article traces the shifting significations of the Royal Crown of Hungary. As an object central to notions of legitimacy in a land that served as a battleground for Eastern and Western powers during the medieval and modern eras, the crown over its contested history has come to be seen as a composite symbol of political independence and Western cultural affiliation. A thorough archaeology of the crown, however, reveals its origins as an eleventh-century diadem designed for a Byzantine princess. Subsequently this open crown was transformed into the closed crown worn by the king of a powerful and emerging Western monarchy. In the process of this re-gendering, the object was reconceived as papal gift. Bridging both instantiations is the crown's status as a gift, replete with associations of power and subjugation that anthropologists of gift-giving practices have long recognized. [source] Fluorescence Bronchoscopy for Selection of Surgical Procedure in Patients With Early Staged Endobronchial CarcinomaARTIFICIAL ORGANS, Issue 4 2005Yoshio Tsunezuka Abstract:, Background: It is sometimes difficult to determine the extent of resection in patients with endobronchial carcinoma because preoperative white-light bronchoscopic (WLB), examination, is, not, sensitive, enough, to, examine, the extent fully. Light-Induced Fluorescence Endoscopy (LIFE) is recognized as a useful modality for the diagnosis of early staged bronchial carcinoma, but there have been no reports of its significance in surgical treatment. We have studied the influence of LIFE upon the selection of surgical procedures or other treatments in patients with endobronchial carcinoma preoperatively. Methods: Conventional WLB and LIFE were performed within 7 days of operation. Biopsy specimens were taken from the marginal regions of the areas that were suspicious for malignancy on LIFE examination and WLB. We decided the resection line before operation and kept the resected central margin 1 cm apart from the area revealed as suspicious by LIFE. Results: From January 1999 to March 2003, 75 patients underwent LIFE. LIFE was performed to decide the surgical procedures for 12 patients (16.0%). Surgical therapy was performed in 8 (66.7%). LIFE findings dramatically changed the surgical procedures for 3 patients, lobectomy changed to sleeve lobectomy in 2 and laser therapy to segmentectomy in 1. LIFE revealed larger abnormal areas of bronchial cancer compared to WLB in 7 (58.3%). Conversely, WLB overestimated the extent of abnormal area in 1 (8.3%). WLB revealed the same cancer area as LIFE in 4. In all patients, the resected bronchial margins were cancer free intraoperatively and postoperatively. Conclusion: LIFE can be more sensitive than WLB and be more beneficial for judging the extent of neoplastic bronchial changes for some patients. LIFE may be a useful modality for the preoperative selection of surgical procedures, especially whether sleeve resection is needed or not, for some centrally located superficial endobronchial carcinoma. [source] ON THE CHANGE POINT OF THE MEAN RESIDUAL LIFE OF SERIES AND PARALLEL SYSTEMSAUSTRALIAN & NEW ZEALAND JOURNAL OF STATISTICS, Issue 1 2010Yan Shen Summary This paper considers the mean residual life in series and parallel systems with independent and identically distributed components and obtains relationships between the change points of the mean residual life of systems and that of their components. Compared with the change point for single components, should it exists, the change point for a series system occurs later. For a parallel system, however, the change point is located before that for the components, if it exists at all. Moreover, for both types of systems, the distance between the change points of the mean residual life for systems and for components increases with the number of components. These results are helpful in the determination of optimal burn-in time and related decision making in reliability analysis.

Bernheim argued that overall QOL is best captured as the Gestalt3 of a global self-assessment and suggested that the Anamnestic Comparative Self Assessment (ACSA) approach, in which subjects' memories of the best and worst times of their lives are used to anchor a Visual Analog Scale (VAS), provided a serious answer to the serious question, ,How have you been?' Bernheim compares and contrasts the ACSA to multi-item questionnaire QOL instruments, such as the SF-36, concluding that the ACSA has a number of advantages. His discussion assumes that the use of QOL outcomes in clinical trials is both relevant and appropriate. In the present paper, we document the reasonableness of this latter assumption,4 contribute to the characterization of the similarities and differences between multi-item and individualized QOL instruments, and point to some other individualized instruments that may be used in clinical trial contexts. These ,other individualized instruments' differ from the ACSA in fundamental ways; but they are individualized in that the subject defines those areas in his/her life that are most important, and these may vary from subject-to-subject. [source] ENACTMENTS: MOVING FROM DEADLY WAYS OF RELATING TO THE BEGINNINGS OF MENTAL LIFEBRITISH JOURNAL OF PSYCHOTHERAPY, Issue 2 2008David Morgan abstract The author discusses the vicissitudes of working analytically with patients who present with monolithic forms of thinking. He describes an approach that emphasizes the importance of the analyst as a real object that has at first to be explored to discover whether or not what is projected corresponds to the analyst's mind. This exploration of the other often confronts the analyst with their own issues surrounding sanity and madness, life and death; it is through this exploration of these real anxieties in the mind of the object that can lead to the beginnings of thinking in severely ill patients. [source] ENVELOPING OBJECTS: ALLEGORY AND COMMODITY FETISH IN WENCESLAUS HOLLAR'S PERSONIFICATIONS OF THE SEASONS AND FASHION STILL LIFESART HISTORY, Issue 3 2006JOSEPH MONTEYNE While in London during the 1640s Wenceslaus Hollar produced a striking cycle of etchings using contemporary female figures as allegories of the seasons, followed by another series of still lifes depicting fashion accessories, in which fur muffs appear repeatedly. This article focuses on the connections between the personi-fications of winter and the still lifes, and brings out the tensions that transpire when the disinterested and supposedly objective eye utilized in Hollar's other projects of the 1640s is revealed as an eye steeped with ambivalent desires , not just in relation to the bodies of certain women, but to the commodity form as well. The fur muff in these etchings is shown to be an enigmatic entity, not only intersecting with issues related to fetishism, eroticism and urban space in early modern London, but is also poised on a threshold between different economies of the object, between residual classical and medieval systems of representation and newly emergent anxieties about the commodity and exchange value.
