It has been found in starch-rich foods cooked at high temperatures. Vacuum frying (10 Torr) was investigated as a possible alternative to reduce acrylamide formation in potato chips. The cultivar Atlantic was used to determine the kinetics of acrylamide formation during traditional and vacuum frying at different temperatures. There was a 94% decrease in acrylamide content when potatoes were fried to the same final moisture content (1.5% ± 0.3% w.b.) under vacuum compared to those fried under atmospheric conditions. Acrylamide accumulation under vacuum frying was modeled using first-order kinetics (during traditional frying, the logistic kinetic model was used). The behavior of the kinetics of acrylamide content in potato chips fried under the two processes was different mainly because of the different temperatures used. During traditional frying, higher temperatures are used (150 to 180C) and acrylamide after some time is produced but starts degrading, producing a constant level of acrylamide content at longer times. During vacuum frying (10 Torr), acrylamide increased exponentially (but at lower levels) for all frying times.

King First page of article [source] BREACH AND FULFILLMENT OF THE PSYCHOLOGICAL CONTRACT: A COMPARISON OF TRADITIONAL AND EXPANDED VIEWSPERSONNEL PSYCHOLOGY, Issue 4 2003LISA SCHURER LAMBERT Breach and fulfillment in a psychological contract has traditionally been studied with approaches that are conceptually and methodologically limited. We compared predictions derived from the traditional view to predictions from an expanded view that maintains the distinction between promised and delivered inducements and examines their joint relationship with employee satisfaction. The traditional and expanded views were compared using longitudinal data and polynomial regression analysis. Results provided little support for the traditional view. In contrast, results supported the expanded view and revealed that relationships for breach and fulfillment are more complex than previously suggested. Specifically, satisfaction depended on whether breach represented deficient or excess inducements and the particular inducement under consideration. Moreover, satisfaction was more strongly related to delivered inducements than promised inducements. These results question basic tenets of psychological contract research and indicate new avenues for research that build on the expanded view developed in this article. [source] Clinical and Economic Factors Associated with Ambulance Use to the Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 8 2006Jennifer Prah Ruger PhD Background: Concern about ambulance diversion and emergency department (ED) overcrowding has increased scrutiny of ambulance use. Knowledge is limited, however, about clinical and economic factors associated with ambulance use compared to other arrival methods. Objectives: To compare clinical and economic factors associated with different arrival methods at a large, urban, academic hospital ED. Methods: This was a retrospective, cross-sectional study of all patients seen during 2001 (N= 80,209) at an urban academic hospital ED. Data were obtained from hospital clinical and financial records. Outcomes included acuity and severity level, primary complaint, medical diagnosis, disposition, payment, length of stay, costs, and mode of arrival (bus, car, air-medical transport, walk-in, or ambulance). Multivariate logistic regression identified independent factors associated with ambulance use. Results: In multivariate analysis, factors associated with ambulance use included: triage acuity A (resuscitation) (adjusted odds ratio [OR], 51.3; 95% confidence interval [CI] = 33.1 to 79.6) or B (emergent) (OR, 9.2; 95% CI = 6.1 to 13.7), Diagnosis Related Group severity level 4 (most severe) (OR, 1.4; 95% CI = 1.2 to 1.8), died (OR, 3.8; 95% CI = 1.5 to 9.0), hospital intensive care unit/operating room admission (OR, 1.9; 95% CI = 1.6 to 2.1), motor vehicle crash (OR, 7.1; 95% CI = 6.4 to 7.9), gunshot/stab wound (OR, 2.1; 95% CI = 1.5 to 2.8), fell 0,10 ft (OR, 2.0; 95% CI = 1.8 to 2.3). Medicaid Traditional (OR, 2.0; 95% CI = 1.4 to 2.4), Medicare Traditional (OR, 1.8; 95% CI = 1.7 to 2.1), arrived weekday midnight,8 AM (OR, 2.0; 95% CI = 1.8 to 2.1), and age ,65 years (OR, 1.3; 95% CI = 1.2 to 1.5). Conclusions: Ambulance use was related to severity of injury or illness, age, arrival time, and payer status. Patients arriving by ambulance were more likely to be acutely sick and severely injured and had longer ED length of stay and higher average costs, but they were less likely to have private managed care or to leave the ED against medical advice, compared to patients arriving by independent means.

Lakoski Abstract:, Selective estrogen receptor modulators (SERMs) have been used successfully in the treatment of breast cancer and osteoporosis while Tibolone has been used extensively in Europe for the treatment of menopausal symptoms. Limited data is available on the effect of these agents on the cardiovascular system. Traditional and novel lipid markers are valuable in determining patients at increased cardiovascular risk. The purpose of this article is to discuss the mechanism of action of Tamoxifen, Raloxifene and Tibolone and their effects on lipid metabolism. [source] Biodiversity in tropical agroforests and the ecological role of ants and ant diversity in predatory functionECOLOGICAL ENTOMOLOGY, Issue 4 2006STACY M. PHILPOTT Abstract 1.,Intensive agricultural practices drive biodiversity loss with potentially drastic consequences for ecosystem services. To advance conservation and production goals, agricultural practices should be compatible with biodiversity. Traditional or less intensive systems (i.e. with fewer agrochemicals, less mechanisation, more crop species) such as shaded coffee and cacao agroforests are highlighted for their ability to provide a refuge for biodiversity and may also enhance certain ecosystem functions (i.e. predation). 2.,Ants are an important predator group in tropical agroforestry systems. Generally, ant biodiversity declines with coffee and cacao intensification yet the literature lacks a summary of the known mechanisms for ant declines and how this diversity loss may affect the role of ants as predators. 3.,Here, how shaded coffee and cacao agroforestry systems protect biodiversity and may preserve related ecosystem functions is discussed in the context of ants as predators. Specifically, the relationships between biodiversity and predation, links between agriculture and conservation, patterns and mechanisms for ant diversity loss with agricultural intensification, importance of ants as control agents of pests and fungal diseases, and whether ant diversity may influence the functional role of ants as predators are addressed. Furthermore, because of the importance of homopteran-tending by ants in the ecological and agricultural literature, as well as to the success of ants as predators, the costs and benefits of promoting ants in agroforests are discussed. 4.,Especially where the diversity of ants and other predators is high, as in traditional agroforestry systems, both agroecosystem function and conservation goals will be advanced by biodiversity protection. [source] A comparison of the physicochemical, microbiological and aromatic composition of Traditional and Industrial Leben in TunisiaINTERNATIONAL JOURNAL OF DAIRY TECHNOLOGY, Issue 1 2010OLFA SAMET-BALI Traditional Tunisian Leben (TL) was produced according to the traditional method. Physicochemical and microbiological characteristics and major aromatic compounds were studied and compared to industrial Leben (IL) and experimental Leben (EL). The results show a decrease in lactose content and pH value and an increase in lactic acid during spontaneous fermentation. TL and EL were characterised by higher protein, lactose and ash contents but were less fatty and acidic than IL. Lactic acid bacteria (LAB) and yeasts present in TL were responsible for lactic acid fermentation and aroma development. The LAB and yeast counts in TL were higher than that in EL and IL. Dynamic headspace extraction procedure shows the existence of four major volatile compounds: acetaldehyde, ethanol, diacetyl and acetoin in TL, IL and EL. However, TL has the most important quantity of aroma. [source] The Ties Made in the Harvest: Nicaraguan Farm-worker Networks in Costa Rica's Agricultural ExportsJOURNAL OF AGRARIAN CHANGE, Issue 4 2010SANG E. LEE Traditional and nontraditional export agriculture expansion dramatically changed the social and economic landscapes in the global south. An examination of one aspect of south,south international migration, Nicaraguan migrant economic integration into Costa Rica's export agriculture sector, reveals how production systems in the traditional and nontraditional agricultural sectors shape migrant social networks in distinct ways in the global south and its significance for both migrant workers and the agricultural sectors they work in. The rapid expansion of nontraditional export agriculture , the essence of agricultural development in Costa Rica , depends on the traditional crop production structure of coffee farms. The experiences of Nicaraguan migrant workers and their social ties to each other in nontraditional export agriculture and the coffee farms in Costa Rica demonstrate how different production structures call for distinct fragile and conflicted social networks ties between migrants. The economic integration of migrant workers relies on opportunistic and weak ties that are both gendered and contradictory. [source] The Role of Racial Identity in Perceived Racism and Psychological Stress Among Black American Adults: Exploring Traditional and Alternative ApproachesJOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 5 2010Alex L. Pieterse This investigation tested whether racial identity status attitudes moderated the relationship between perceived racism and psychological functioning in a sample of 340 Black American adults. The study utilized 2 approaches to racial identity assessment: the standard group-means approach, plus a profile analysis of individual racial identity statuses. Results based on the group-means approach indicated that racial identity did not moderate the relationship between racism and psychological functioning. Findings based on the profile analysis, however, indicated that individuals whose profile type was identified as internalization-dominant exhibited the lowest levels of general life stress, the lowest levels of psychological distress, and the highest levels of psychological well-being. Implications for ongoing research are discussed. [source] Are parametric models suitable for estimating avian growth rates?JOURNAL OF AVIAN BIOLOGY, Issue 4 2007William P. Brown For many bird species, growth is negative or equivocal during development. Traditional, parametric growth curves assume growth follows a sigmoidal form with prescribed inflection points and is positive until asymptotic size. Accordingly, these curves will not accurately capture the variable, sometimes considerable, fluctuations in avian growth over the course of the trajectory. We evaluated the fit of three traditional growth curves (logistic, Gompertz, and von Bertalanffy) and a nonparametric spline estimator to simulated growth data of six different specified forms over a range of sample sizes. For all sample sizes, the spline best fit the simulated model that exhibited negative growth during a portion of the trajectory. The Gompertz curve was the most flexible for fitting simulated models that were strictly sigmoidal in form, yet the fit of the spline was comparable to that of the Gompertz curve as sample size increased. Importantly, confidence intervals for all of the fitted, traditional growth curves were wholly inaccurate, negating the apparent robustness of the Gompertz curve, while confidence intervals of the spline were acceptable. We further evaluated the fit of traditional growth curves and the spline to a large data set of wood thrush Hylocichla mustelina mass and wing chord observations. The spline fit the wood thrush data better than the traditional growth curves, produced estimates that did not differ from known observations, and described negative growth rates at relevant life history stages that were not detected by the growth curves. The common rationale for using parametric growth curves, which compress growth information into a few parameters, is to predict an expected size or growth rate at some age or to compare estimated growth with other published estimates. The suitability of these traditional growth curves may be compromised by several factors, however, including variability in the true growth trajectory. Nonparametric methods, such as the spline, provide a precise description of empirical growth yet do not produce such parameter estimates. Selection of a growth descriptor is best determined by the question being asked but may be constrained by inherent patterns in the growth data. [source] Land-use and resource conflicts in the Okavango Delta, BotswanaAFRICAN JOURNAL OF ECOLOGY, Issue 2009Michael B. K. Darkoh Abstract This study assesses land-use conflicts in the Okavango wetland ecosystem. A survey of the livelihood activities of a sample of four villages has been carried out and a stakeholder approach used to identify and analyse the key actors involved in resource competition and conflicts in the area. Traditional and emerging stakeholders were identified and found to be in conflict not only with each other but within themselves. Institutional policies on land use in the area are not properly harmonized, and there has been a top-down approach to development planning and implementation of development programmes. As a result, land-use conflicts have escalated in the area. The Okavango Delta Management Plan adopted in 2007 should integrate and harmonize all the land-use policies, and land management in the area. [source] Nursing home care: whodunit?JOURNAL OF CLINICAL NURSING, Issue 11 2006Aggie TG Paulus PhD Aims and objectives., (1) To analyse and compare (changes and differences in) activity profiles of various types of nursing home care. (2) To assess the impact of integrated care on these activity profiles. Background., Because of an ongoing introduction of integrated nursing home care, caregivers increasingly have to co-ordinate their activities, engage into interprofessional relationships and take over each other's tasks. Consequently, activity profiles [i.e. combinations of (contributions to) care activities and the roles that perform them] are expected to change. Design/methods., At three measurement points in the period 1999,2003, caregivers (in 18 different roles) recorded and listed direct and indirect care activities. A total of 41 335 lists were analysed to derive activity profiles of traditional, transitional and integrated nursing home care in the Netherlands. Results., Traditional, transitional and integrated care shared some comparable activity profiles. Integrated care differed from the other types with respect to the contribution of the geriatric nurse, recreational activities supervisor, nutrition assistant, household assistant and nursing assistant to activities such as extra care, handling food and club activities. Contrary to the other roles, the licensed practical nurse contributed to (almost) all activities in all types of care. Conclusions., Nursing home care has several recurring activity profiles. These profiles are the same in all types of nursing home care. The introduction of integrated care implies that particular profiles have to be added to these profiles. As a generalist, the licensed practical nurse seems to play a key role in all activity profiles. Relevance to clinical practice., Because of demographic and financial pressures, integrated care for older people becomes increasingly important. By addressing the impact of integrated care on activity profiles, this paper provides information on how new types of care can be delivered in the most effective manner. [source] Assessing Goodness of Fit of Item Response Theory Models: A Comparison of Traditional and Alternative ProceduresJOURNAL OF EDUCATIONAL MEASUREMENT, Issue 4 2003Clement A. Stone Testing the goodness of fit of item response theory (IRT) models is relevant to validating IRT models, and new procedures have been proposed. These alternatives compare observed and expected response frequencies conditional on observed total scores, and use posterior probabilities for responses across , levels rather than cross-classifying examinees using point estimates of , and score responses. This research compared these alternatives with regard to their methods, properties (Type 1 error rates and empirical power), available research, and practical issues (computational demands, treatment of missing data, effects of sample size and sparse data, and available computer programs). Different advantages and disadvantages related to these characteristics are discussed. A simulation study provided additional information about empirical power and Type 1 error rates. [source] Traditional versus unobserved components methods to forecast quarterly national account aggregatesJOURNAL OF FORECASTING, Issue 2 2007Gustavo A. Marrero Abstract We aim to assess the ability of two alternative forecasting procedures to predict quarterly national account (QNA) aggregates. The application of Box,Jenkins techniques to observed data constitutes the basis of traditional ARIMA and transfer function methods (BJ methods). The alternative procedure exploits the information of unobserved high- and low-frequency components of time series (UC methods). An informal examination of empirical evidence suggests that the relationships between QNA aggregates and coincident indicators are often clearly different for diverse frequencies. Under these circumstances, a Monte Carlo experiment shows that UC methods significantly improve the forecasting accuracy of BJ procedures if coincident indicators play an important role in such predictions. Otherwise (i.e., under univariate procedures), BJ methods tend to be more accurate than the UC alternative, although the differences are small. We illustrate these findings with several applications from the Spanish economy with regard to industrial production, private consumption, business investment and exports.,,Copyright © 2007 John Wiley & Sons, Ltd. [source] Comparative Energy, Environmental, and Economic Analysis of Traditional and E-commerce DVD Rental NetworksJOURNAL OF INDUSTRIAL ECOLOGY, Issue 3 2007Deepak Sivaraman This study is a comparative life-cycle assessment (LCA) of two competing digital video disc (DVD) rental networks: the e-commerce option, where the customer orders the movies online, and the traditional business option, where the customer goes to the rental store to rent a movie. The analytical framework proposed is for a customer living in the city of Ann Arbor, Michigan in the United States. The primary energy and environmental performance for both networks are presented using a multicriterion LCA. The package selected by the traditional network is responsible for 67% of the difference in total energy consumption of the two alternatives. Results show that the e-commerce alternative consumed 33% less energy and emitted 40% less CO2 than the traditional option. A set of sensitivity analyses test the influence of distance traveled, transportation mode, and reuse of DVD and DVD packaging on the final results. The mode of transportation used by the customer in the traditional business model also affects global emissions and energy consumption. The customer walking to the store is by far the best option in the traditional network; however, the e-commerce option performed comparatively better despite all transportation modes tested. A novel economic indicator, ESAL, is used to compare different transportation modes based on the level of stress exerted on the pavement. The two networks are compared on the basis of cost accounting; consistent with its energy and environmental advantages, the e-commerce network also exerts lesser economic impact, by $1.17, for the functional unit tested. [source] Reasonably Traditional: Self,Contradiction and Self,Reference in Alasdair MacIntyre's Account of Tradition,Based RationalityJOURNAL OF RELIGIOUS ETHICS, Issue 3 2002Micah Lott Alasdair MacIntyre's account of tradition,based rationality has been the subject of much discussion, as well as the object of some recent charges of inconsistency. The author considers arguments by Jennifer Herdt, Peter Mehl, and John Haldane which attempt to show that MacIntyre's account of rationality is, in some way, inconsistent. It is argued that the various charges of inconsistency brought against MacIntyre by these critics can be understood as variations on two general types of criticism: (1) that MacIntyre's account of tradition,based rationality presents a picture of rationality with inconsistent internal elements, and (2) that MacIntyre, in the act of presenting his picture of rationality, makes the sort of claims to which his own account of rationality denies legitimacy, and thus MacIntyre's account is self,referentially incoherent. In response to criticisms of the first sort, it is argued that MacIntyre can further clarify or develop his position to take the current criticisms into account without altering the fundamental aspects of his picture of rationality. In response to the charge of self,referential incoherence, it is argued that the charge rests on a mistaken understanding of MacIntyre's position and of the nature of justification. In dealing with these arguments, the author hopes to not only vindicate MacIntyre's account of rationality against the charges of some of its recent critics, but also to shed some light on the nature of arguments both for and against relativism and historicism.

Girves Mentoring can be an effective strategy in improving retention of college students and faculty from fields where historical underrepresentation has occurred. This article reviews the benefits of mentoring in higher education, and identifies components of effective mentoring strategies that promote educational and career advancement. It illustrates how effective programs can be institutionalized and scaled through consortial and national collaborations. Traditional and alternative mentoring models are described through four successful programs designed to increase the academic and professional success of undergraduates, graduate students, and junior faculty. The article concludes with a set of general recommendations and caveats gleaned from the literature and programs reviewed. [source] Combining pharmacotherapy with cognitive behavioral therapy: Traditional and new approachesJOURNAL OF TRAUMATIC STRESS, Issue 5 2006Michael Davis Given the ever-increasing sources of trauma both nationally and globally, it is imperative to develop new and better treatments for anxiety disorders such as posttraumatic stress disorder (PTSD). This review is a collection of presentations that seek to do just that, either by using pharmacotherapy to try to prevent or erase the formation of traumatic fear memories, or to enhance exposure-based cognitive,behavioral therapy using pharmacological agents that have been effective in enhanced extinction of fear in rodents. [source] The Whole Universe Is My Cathedral: A Contemporary Navajo Spiritual SynthesisMEDICAL ANTHROPOLOGY QUARTERLY, Issue 4 2000David H. Begay This article discusses the three major spiritual healing ways used by Navajo Indians today: Traditional healing practices that have been used for generations and still have a dynamic existence relevant to everyday Navajo life; Christian healing traditions, ranging from Catholic Charismatic to Protestant Pentecostal; and practices of the Native American Church (NAC). The complex relationship among these healing traditions on the Navajo reservation is examined through a case study of a Navajo woman whose personal spirituality includes all three. Faced with serious medical problems, this devout Catholic turned to Navajo Traditional and Native American Church spiritual diagnosis and treatment. This analysis is the occasion for a reflection on the contemporary relevance of the kind of spiritual synthesis characterized in this woman's experience.

JACKSON ABSTRACT In this article, we analyze a crisis that resulted when a vehicular road was illegally cut through a corner of southern Colombia's San Agustín Archaeological Park, a UNESCO-designated World Heritage site, by a nearby reindigenizing Yanacona community and its neighboring campesino allies. In numerous meetings addressing the crisis, Yanacona leaders, performing on a transnational and cosmopolitan stage, have asserted and justified their position by creatively combining local and "authentic" discourses with significantly scaled-up heritage, developmentalist, and environmentalist ones. Yanacona articulate and adapt their ethnicity to an evolving global reification of diversity as well as fashion a symbolics of citizenship that critiques modernity but cannot be called "traditional."[reindigenization, heritage, performativity, state,indigenous relations, politics of culture, cultural tourism, Colombia] [source] Traditional, complementary and alternative medicine and cancer care: an international analysis of grassroots integration.PSYCHO-ONCOLOGY, Issue 9 2008Alex Broom., John Chatwin, Written by Philip Tovey No abstract is available for this article. [source] How Networks Explain Unintended Policy Implementation Outcomes: The Case of UK Rail PrivatizationPUBLIC ADMINISTRATION, Issue 4 2001Andrew Grantham How a government secures the implementation of its policies is one of the most interesting processes in public administration. The tendency of scholars is to ignore implementation and how it impacts on the form of policy, something which invariably changes once resources have been allocated to implementing agencies and the policy detail is addressed. Traditional ,top-down' (Pressman and Wildavsky 1984, Mazmanian and Sabatier 1981) and ,bottom-up' (Elmore 1979, Hjern and Porter 1981, Hull and Hjern 1983) analytical frameworks give only a partial explanation of outcomes. In making the case for a netwrok approach, a typology of implementation networks is presented. The utility of this typology is evaluated in the context of one of the most complex privatization programmes attempted by any government: the privatization of British Rail (BR) between 1992 and 1997. In the case of the sale of one BR subsidiary train operating company, ScotRail, a variety of agencies with competing interests and acting in a politically-charged climate exchanged essential resources to deliver the policy, though not without generating unintended outcomes in the form of significant change to the policy and the agencies charged with implementing it. [source] Premature atherosclerosis in pediatric systemic lupus erythematosus: Risk factors for increased carotid intima-media thickness in the atherosclerosis prevention in pediatric lupus erythematosus cohort,ARTHRITIS & RHEUMATISM, Issue 5 2009Laura E. Schanberg Objective To evaluate risk factors for subclinical atherosclerosis in a population of patients with pediatric systemic lupus erythematosus (SLE). Methods In a prospective multicenter study, a cohort of 221 patients underwent baseline measurements of carotid intima-media thickness (CIMT) as part of the Atherosclerosis Prevention in Pediatric Lupus Erythematosus (APPLE) trial. SLE disease measures, medications, and traditional risk factors for atherosclerosis were assessed. A standardized protocol was used to assess the thickness of the bilateral common carotid arteries and the mean maximal IMT of 12 segments. Univariable analysis identified potential associations with CIMT, which were examined in multivariable linear regression modeling. Results Based on the mean-mean common or the mean-max CIMT as the dependent variable, univariable analysis showed significant associations of the following variables with increased CIMT: increasing age, longer SLE duration, minority status, higher body mass index (BMI), male sex, increased creatinine clearance, higher lipoprotein(a) level, proteinuria, azathioprine treatment, and prednisone dose. In multivariable modeling, both azathioprine use (P = 0.005 for the mean-mean model and P = 0.102 for the mean-max model) and male sex (P < 0.001) were associated with increases in the mean-max CIMT. A moderate dosage of prednisone (0.15,0.4 mg/kg/day) was associated with decreases in the mean-max CIMT (P = 0.024), while high-dose and low-dose prednisone were associated with increases in the mean-mean common CIMT (P = 0.021) and the mean-max CIMT (P = 0.064), respectively. BMI (P < 0.001) and creatinine clearance (P = 0.031) remained associated with increased mean-mean common CIMT, while increasing age (P < 0.001) and increasing lipoprotein(a) level (P = 0.005) were associated with increased mean-max CIMT. Conclusion Traditional as well as nontraditional risk factors were associated with increased CIMT in this cohort of patients in the APPLE trial. Azathioprine treatment was associated with increased CIMT. The relationship between CIMT and prednisone dose may not be linear. [source] Chinese values in Singapore: Traditional and modernASIAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 1 2003Weining C. Chang A series of three studies was conducted to test the internal structure of the Chinese value hierarchy (CVH) in Singapore. Study 1 identified the empirically best,fit model with six factors: Prudence, Industry, Civic,Harmony, Moral Development, Social Power and Moderation. Relative magnitudes and interfactor correlations suggested that these factors could be further grouped into two superordinate clusters: (i) The Modern factor, with significantly higher magnitude, consisted of Prudence, Industry, Civic,Harmony and Moral Development; and (ii) the Tradition factor, with lower magnitude, consisted of Social Power and Moderation. Study 2 surveyed university students with differential preference for language usages: English or Chinese. Both language groups were equally high on the Modern factor, but the Chinese,language,preferred group showed a significantly higher endorsement for the Tradition factor, Chinese Worldview (CWV) and Chinese Health Beliefs (CHB). Further convergent validation for the Modern and the Tradition factors was provided by investigating their correlations with traditional Chinese beliefs and practices for the two language groups separately. Study 3 tested generation differences in CVH. University participants (Self) were compared with their parents (Parents) and friends (Friends). There were no differences between Self and Friends on both the Modern and Tradition factors, CWV and individual differences of modernity. Parents and Self did not differ on individual differences of modernity. Parents, however, were higher on the Modern factor, the Tradition factor and CWV. Results were discussed to support the concept of ,multiple modernity' (Tu, 1900) in Asian societies, and the ,revised convergence hypothesis' proposed by Yang (1988). [source] Influence of postharvest water stress on lipoxygenase and alcohol dehydrogenase activities, and on the composition of some volatile compounds of Gewürztraminer grapes dehydrated under controlled and uncontrolled thermohygrometric conditionsAUSTRALIAN JOURNAL OF GRAPE AND WINE RESEARCH, Issue 3 2007L. CHKAIBAN ABSTRACT Gewürztraminer grapes with a sugar content of around 212 g/L (21.7oBrix) were dried at 17oC, 40% relative humidity and 1.5 m/sec air flow in a 300 L thermo-conditioned tunnel. Control grapes were dried traditionally in a window ventilated room, under uncontrolled environmental conditions varying with outside climate. Tunnel-dried grapes reached the desired sugar concentration (305 g/L, 29.5oBrix) in 17 days, loosing 36% of their weight. Control grapes lost only 22% of their weight and grey mould developed in several bunches at the last sampling. Titratable acidity decreased for tunnel-dried and control grapes from 6.5 g/L to 4 g/L and 5 g/L, respectively. Lipoxygenase (LOX) activity declined in both samples from 120 to 90 U/mg protein dw, with a subsequent significant increase after 20% weight loss in tunnel-treated grapes while the control grapes showed a small peak (150 U/mg protein dw) at 13% weight loss. Six carbon compound evolution showed a loose correlation with LOX activity. Alcohol dehydrogenase specific activity and the concentrations of ethanol and of acetaldehyde plus ethyl acetate showed fluctuating patterns of change, with the evolution of these three variables showing similarity, particularly evident in the tunnel-dried grapes. Carotenoids declined significantly, to increase slightly at the end of the experiment in both samples, with the decline more rapid in the control grapes. Traditional, uncontrolled conditions, did not permit constant dehydration, and provoked a rapid stress to the berries (10% of weight loss). Controlled conditions permitted uniform dehydration, postponed water stress, giving a higher quality product without loss of berries. [source] Cannabinoid CB2 receptors in the gastrointestinal tract: a regulatory system in states of inflammationBRITISH JOURNAL OF PHARMACOLOGY, Issue 2 2008K L Wright The emerging potential for the cannabinoid (CB) system in modulating gastrointestinal inflammation has gained momentum over the last few years. Traditional and anecdotal use of marijuana for gastrointestinal disorders, such as diarrhoea and abdominal cramps is recognized, but the therapeutic benefit of cannabinoids in the 21st century is overshadowed by the psychoactive problems associated with CB1 receptor activation. However, the presence and function of the CB2 receptor in the GI tract, whilst not yet well characterized, holds great promise due to its immunomodulatory roles in inflammatory systems and its lack of psychotropic effects. This review of our current knowledge of CB2 receptors in the gastrointestinal tract highlights its role in regulating abnormal motility, modulating intestinal inflammation and limiting visceral sensitivity and pain. CB2 receptors represent a braking system and a pathophysiological mechanism for the resolution of inflammation and many of its symptoms. CB2 receptor activation therefore represents a very promising therapeutic target in gastrointestinal inflammatory states where there is immune activation and motility dysfunction.

Hirneisen ABSTRACT:, Over one-half of foodborne illnesses are believed to be viral in origin. The ability of viruses to persist in the environment and foods, coupled with low infectious doses, allows even a small amount of contamination to cause serious problems. An increased incidence of foodborne illnesses and consumer demand for fresh, convenient, and safe foods have prompted research into alternative food-processing technologies. This review focuses on viral inactivation by both traditional processing technologies such as use of antimicrobial agents and the application of heat, and also novel processing technologies including high-pressure processing, ultraviolet- and gamma-irradiation, and pulsed electric fields. These industrially applicable control measures will be discussed in relation to the 2 most common causes of foodborne viral illnesses, hepatitis A virus and human noroviruses. Other enteric viruses, including adenoviruses, rotaviruses, aichi virus, and laboratory and industrial viral surrogates such as feline caliciviruses, murine noroviruses, bacteriophage MS2 and ,X174, and virus-like particles are also discussed. The basis of each technology, inactivation efficacy, proposed mechanisms of viral inactivation, factors affecting viral inactivation, and applicability to the food industry with a focus on ready-to-eat foods, produce, and shellfish, are all featured in this review. [source] Control of Pathogenic and Spoilage Microorganisms in Fresh-cut Fruits and Fruit Juices by Traditional and Alternative Natural AntimicrobialsCOMPREHENSIVE REVIEWS IN FOOD SCIENCE AND FOOD SAFETY, Issue 3 2009Rosa M. Raybaudi-Massilia ABSTRACT:, Traditional antimicrobials have been extensively used for many years. However, consumers are currently demanding wholesome, fresh-like, and safe foods without addition of chemically synthesized preservatives. The application of novel natural antimicrobials to assure safety of fresh-cut fruits and unpasteurized juices while preventing quality loss is a promising alternative. The effectiveness of these natural substances added to fruit derivatives has been studied by different researchers. Antimicrobials of animal (lactoperoxidase, lysozyme, and chitosan), plant (essential oils, aldehydes, esters, herbs, and spices), and microbial origin (nisin) can be used to effectively reduce pathogenic and spoilage microorganisms in fresh-cut fruits and fruit juices. Nevertheless, the use of these compounds at a commercial level is still limited due to several factors such as impact on sensory attributes or, in some cases, regulatory issues concerning their use. Therefore, extensive research on the effects of each antimicrobial on food sensory characteristics is still needed so that antimicrobial substances of natural origin can be regarded as feasible alternatives to synthetic ones.

In particular, they have seized on the idea of a ,progressive consensus' as a means of entrenching a deeper, cultural shift in British society on centre-left terms. This article assesses the potential of social democratic responses to New Labour for fulfilling this task. ,Traditional' and ,modernising' perspectives are identified, each of which have a positive and critical variant. The critical-modernising approach emerges with the greatest potential for moving beyond the New Labour project. Critical-modernisers operate on the Third Way's analytical terrain,recognising the still-changing operating environment of the centre-left. However, they seek simultaneously to develop a political narrative that is distinct from the Third Way. In order to achieve this latter objective, the normative heritage of more traditional approaches remains a key resource for critical-modernisers, as they seek to show how more recognisably social democratic themes can resonate with a rapidly changing social context. [source] Horizontal Roadway Curvature Computation Algorithm Using Vision TechnologyCOMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING, Issue 2 2010Yichang (James) Tsai However, collecting such data is time-consuming, costly, and dangerous using traditional, manual surveying methods. It is especially difficult to perform such manual measurement when roadways have high traffic volumes. Thus, it would be valuable for transportation agencies if roadway curvature data could be computed from photographic images taken using low-cost digital cameras. This is the first article that develops an algorithm using emerging vision technology to acquire horizontal roadway curvature data from roadway images to perform roadway safety assessment. The proposed algorithm consists of four steps: (1) curve edges image processing, (2) mapping edge positions from an image domain to the real-world domain, (3) calibrating camera parameters, and (4) calculating the curve radius and center from curve points. The proposed algorithm was tested on roadways having various levels of curves and using different image sources to demonstrate its capability. The ground truth curvatures for two cases were also collected to evaluate the error of the proposed algorithm. The test results are very promising, and the computed curvatures are especially accurate for curves of small radii (less than 66 m/200 ft) with less than 1.0% relative errors with respect to the ground truth data. The proposed algorithm can be used as an alternative method that complements the traditional measurement methods used by state DOTs to collect roadway curvature data.
