Selected AbstractsAchieving Integrative, Collaborative Ecosystem ManagementCONSERVATION BIOLOGY, Issue 5 2006HEATHER L. KEOUGH beneficios sociales y ecológicos; gestión; participación pública; toma de decisiones cooperativa Abstract:,Although numerous principles have been identified as being important for successfully integrating social and ecological factors in collaborative management, few authors have illustrated how these principles are used and why they are effective. On the basis of a review of the ecosystem management and collaboration literature, we identified eight factors important for integrative, collaborative ecosystem management,integrated and balanced goals, inclusive public involvement, stakeholder influence, consensus group approach, collaborative stewardship, monitoring and adaptive management, multidisciplinary data, and economic incentives. We examined four cases of successful ecosystem management to illustrate how the factors were incorporated and discuss the role they played in each case's success. The cases illustrate that balancing social and ecosystem sustainability goals is possible. Collaborative efforts resulted in part from factors aimed at making plans economically feasible and from meaningful stakeholder participation in ongoing management. It also required participation in monitoring programs to ensure stakeholder interests were protected and management efforts were focused on agreed-upon goals. Data collection efforts were not all-inclusive and systematic; rather, they addressed the ecological, economic, and social aspects of key issues as they emerged over time. Economic considerations appear to be broader than simply providing economic incentives; stakeholders seem willing to trade some economic value for recreational or environmental benefits. The cases demonstrate that it is not idealistic to believe integrative, collaborative ecosystem management is possible in field applications. Resumen:,Aunque numerosos principios han sido identificados como importantes para la integración exitosa de factores sociales y ecológicos en la gestión cooperativa, pocos autores han ilustrado como son utilizados estos principios y porque son efectivos. Con base en una revisión de la literatura sobre gestión de ecosistemas y colaboración, identificamos cinco factores,metas integradas y balanceadas, inclusive participación pública, influencia de grupos de interés, estrategia de consenso en el grupo, gestión cooperativa, gestión adaptativa y monitoreo, datos multidisciplinarios e incentivos económicos,que son importantes para la gestión integradora y cooperativa de ecosistemas. Examinamos cuatro casos de gestión exitosa de ecosistemas para ilustrar como fueron incorporados los factores y discutimos el papel que jugaron en el éxito de cada caso. Los casos ilustran que el balance de metas de sustentabilidad social y ecológica es posible. En parte, los esfuerzos cooperativos resultaron de factores orientados a hacer que los planes fueran económicamente viables y de la participación significativa de grupos de interés en la gestión en curso. También se requirió la participación en programas de monitoreo para asegurar que los intereses de los grupos fueran protegidos y los esfuerzos de gestión se enfocaran en las metas acordadas. No todos los esfuerzos de recolecta de datos fueron incluyentes y sistemáticos, más bien, eran dirigidos a los aspectos ecológicos, económicos y sociales de temas clave a medida que emergían. Las consideraciones económicas parecen ser más amplias que simplemente proporcionar incentivos económicos, los grupos de interés parecen dispuestos a cambiar algo de valor económico por beneficios recreativos o ambientales. Los casos demuestran que no es idealista pensar que es posible aplicar la gestión integradora y cooperativa de ecosistemas en el campo. [source] Biochemical and spectroscopic characterization of the bacterial phytochrome of Pseudomonas aeruginosaFEBS JOURNAL, Issue 8 2005Ronja Tasler Phytochromes are photochromic biliproteins found in plants as well as in some cyanotrophic, photoautotrophic and heterotrophic bacteria. In many bacteria, their function is largely unknown. Here we describe the biochemical and spectroscopic characterization of recombinant bacterial phytochrome from the opportunistic pathogen Pseudomonas aeruginosa (PaBphP). The recombinant protein displays all the characteristic features of a bonafide phytochrome. In contrast with cyanobacteria and plants, the chromophore of this bacterial phytochrome is biliverdin IX,, which is produced by the heme oxygenase BphO in P. aeruginosa. This chromophore was shown to be covalently attached via its A-ring endo-vinyl group to a cysteine residue outside the defined bilin lyase domain of plant and cyanobacterial phytochromes. Site-directed mutagenesis identified Cys12 and His247 as being important for chromophore binding and photoreversibility, respectively. PaBphP is synthesized in the dark in the red-light-absorbing Pr form and immediately converted into a far-red-light-absorbing Pfr-enriched form. It shows the characteristic red/far-red-light-induced photoreversibility of phytochromes. A chromophore analog that lacks the C15/16 double bond was used to show that this photoreversibility is due to a 15Z/15E isomerization of the biliverdin chromophore. Autophosphorylation of PaBphP was demonstrated, confirming its role as a sensor kinase of a bacterial two-component signaling system. [source] The relationship between cultural values and individual work values in the hospitality industryINTERNATIONAL JOURNAL OF TOURISM RESEARCH, Issue 4-5 2005Christopher White Abstract This paper examines the relationship between cultural values and individual work values. Two-hundred and seventy-six hospitality management students from mainland China and western Europe were surveyed and grouped according to their value orientations and multiple discriminate analysis was used to identify differences in work value preferences between the groups. The results indicated that a group consisting of mainly Chinese participants valued characteristics that have been associated with developed Western nations, and unlike previous studies, both groups viewed intrinsic as well as extrinsic work values as being important.

[source] Good Deaths, Bad Deaths, and Preferences for the End of Life: A Qualitative Study of Geriatric OutpatientsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2002Elizabeth K. Vig MD OBJECTIVES: Patient involvement in decision-making has been advocated to improve the quality of life at the end of life. Although the size of the oldest segment of the population is growing, with greater numbers of older adults facing the end of life, little is known about their preferences for the end of life. This study aimed to explore the attitudes of older adults with medical illness about the end of life, and to investigate whether current values could be extended to end-of-life preferences. DESIGN: Descriptive study with interviews using open- and closed-ended questions. SETTING: Patients attending two university-affiliated geriatric clinics were interviewed in a private conference room near the clinic they attended or in their homes. PARTICIPANTS: Sixteen older men and women identified by their physicians as having nonterminal heart disease or cancer. MEASUREMENTS: The interview contained open-ended questions such as: "What are the most important things in your life right now?" and "What would you consider a good/bad death?" The interview also contained closed-ended questions about symptoms, quality of life, and health status. Additional questions elicited preferences for the end of life, such as location of death and the presence of others. The open-ended questions were tape-recorded, transcribed, and analyzed using qualitative methods. The closed-ended questions were analyzed using descriptive statistics. RESULTS: Patients with heart disease and cancer provided similar responses. Participants' views about good deaths, bad deaths, and end-of-life scenarios were heterogeneous. Each participant voiced a unique combination of themes in describing good and bad deaths. Because each participant described a multifaceted view of a good death, for instance, no theme was mentioned by even half of the participants. Participants provided differing explanations for why given themes contributed to good deaths. Currently valued aspects of life were not easily translated into end-of-life preferences. For example, although the majority of participants identified their family as being important, many gave reasons why they did not want their family members present when they died. CONCLUSIONS: Because of the heterogeneity of views and the difficulty in inferring end-of-life preferences from current values, older adults should be asked not only questions about general values, but also specific questions about their end-of-life choices and the reasons for these choices. A thorough understanding of an individual's end-of-life preferences may help health professionals working with older adults develop patient-centered care plans for the end of life. [source] Adolescent motherhood: a Q-methodological re-evaluation of psychological and social outcomesJOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 5 2007Jan Richards Abstract Traditionally, adolescent motherhood has been associated with numerous negative social, psychological and societal outcomes. However, in recent years there has been a gradual acceptance that there are many positive features to adolescent motherhood, but methodological issues have been identified within the field. This study aimed to examine adolescent motherhood from the mothers' own perspectives, exploring their attitudes towards the issues that they described as being important in their lives, by using Q-methodology in an attempt to counter some of these methodological limitations. The mothers within the study appeared to be coping positively in their role in that levels of symptomatology, as determined from questionnaire assessment, appeared to be relatively low and they indicated through Q-sort analysis that motherhood had been beneficial to their lives. Three independent factors (clusters of attitudes) were identified within the sample (N,=,23) which differed over the dimensions of: employment, social support, coping, partner co-habitation, financial support, maternal role satisfaction, aspirations for the future, as well as the nature of the relationship with their child(ren)'s father and their satisfaction with the fathers' role. The significance of these findings with regard to educational and social services is discussed. Copyright © 2007 John Wiley & Sons, Ltd. [source] Interpreting and estimating measures of community phylogenetic structuringJOURNAL OF ECOLOGY, Issue 5 2008Olivier J. Hardy Summary 1To characterize the spatial phylogenetic structure of communities, Hardy & Senterre (2007) (J. Ecol., 95, 493,506) partition Gini,Simpson diversity and its generalization, Rao's entropy, defining IST and PST as the proportion of diversity expressed among sites. 2Interpreting IST as a measure of ,differentiation' between sites is inadequate because low values are actually compatible with high differentiation (low species sharing) in species rich communities. To avoid an inadequate use of IST, for example in conservation biology, we offer a more literal interpretation: IST expresses the ,local species identity excess'. Similarly, PST expresses the ,local phylogenetic similarity excess'. 3Villéger & Mouillot (2008) (J. Ecol., 96, 845,848, this issue) argue that the equations of Hardy & Senterre (2007) to compute diversity are inadequate when sites differ in size, and they provide new expressions weighting sites by their sizes. We argue that whether sites must be weighted equally or not depends on the question being asked. Moreover, actual size and sample size must be distinguished, the latter being important for defining estimators. 4Synthesis. The formulations given by Hardy & Senterre (2007) and by Villéger & Mouillot (2008) are both correct in the specific contexts we detail. [source] EFFECT OF WATER ACTIVITY ON PHYSICAL PROPERTIES OF CONJUGATED LINOLEIC ACID (CLA) MICROCAPSULESJOURNAL OF FOOD PROCESS ENGINEERING, Issue 3 2010MARIBEL JIMENEZ ABSTRACT The physical properties of spray drying powders must be considered for the design of equipment. Conjugated linoleic acid (CLA) microcapsules were spray dried by using the following as wall materials: whey protein concentrate (WPC), a blend of whey protein concentrate,maltodextrins (WPC-MD) and gum arabic (GA). These were prepared and their physical properties were studied. The bulk density, packed density, particle density, compressibility and color of the microcapsules were evaluated in a range of water activities from 0.108 to 0.898. No significant differences in the physical properties were found when WPC was used as a wall material in the microcapsules stored at the whole range of water activities tested. Maltodextrins conferred changes in some of the physical properties of the microcapsules (WPC-MD) upon storage at high water activities. GA microcapsules showed drastic changes in all physical properties studied at water activities above 0.628. PRACTICAL APPLICATIONS This work shows the best conditions for storing conjugated linoleic acid (CLA) microcapsules elaborated with different wall materials, which have been reported to have a high potential as a food additive because of the nutraceutical properties of CLA. This research should reveal the behavior of water activity during storage on physical properties, and make it possible to predict what characteristics need to be added to a food, besides being important for the design of equipment, packing and transport. [source] Temperament and character profile of patients with psoriasisJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 5 2008Abstract Background, Psychosocial factors have been implicated as being important in the onset and/or exacerbation of psoriasis.1 The aim of this study is to examine both the personality factors of patients with psoriasis and the correlations between temperament and character dimensions. Material and methods, A total number of 105 psoriasis patients and 109 healthy individuals were enrolled in the study. Questionnaires including Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Temperament and Character Inventory (TCI) were administered individually. Both groups were evaluated in terms of depression, anxiety and characteristic features by using these psychological tests and compared statistically. The relationship between psoriasis area and severity index (PASI) score and the BDI, BAI and TCI scales were also evaluated. Results, The mean BDI score of the psoriasis group were significantly higher than the control group. The psoriasis group had significantly higher scores of harm avoidance and lower scores of being self-directedness than the control group. The duration of psoriasis and the PASI scores were not correlated with BDI and BAI scores. Conclusion, The current study shows that psoriasis patients have distinctive temperament and character dimensions when compared with the control group. We suggest that evaluation and treatment of psoriasis should also include psychosomatic approaches in clinical practice. [source] Tremor induced by thalamic deep brain stimulation in patients with complex regional facial pain,MOVEMENT DISORDERS, Issue 8 2004Constantine Constantoyannis MD Abstract We report on two patients who developed a new postural and action tremor after chronic stimulation of the contralateral thalamus (VPM nucleus) during treatment of a complex regional facial pain syndrome. The tremor was only present during deep brain stimulation (DBS) and was suppressed with adjustment of the stimulation parameters. Tremor was seen only with low frequency stimulation (50 Hz or lower) and disappeared with higher stimulation frequencies. In addition to being an unusual side effect of thalamic DBS, we believe that this phenomenon affords insight into one possible mechanism underlying essential tremor (ET). A central oscillatory mechanism involving the olivocerebellar complex and the thalamus, which is a part of the cerebro,cerebello,cerebral circuit, is thought to play an important role in the genesis of ET. Induction of a tremor resembling ET in our patients indicates an active role for low frequency stimulation. A plausible explanation for this is that low frequency stimulation in the thalamic area enhances the output of the tremor-producing network. This leads credence to the concept of central oscillations in a "tremor circuit," of which the thalamus is a part, as being important in ET. © 2004 Movement Disorder Society [source] Plasticity of the phonotactic selectiveness of four species of chirping crickets (Gryllidae): Implications for call recognitionPHYSIOLOGICAL ENTOMOLOGY, Issue 2 2010JOHN STOUT Earlier studies of phonotaxis by female crickets describe this selective behavioural response as being important in the females' choices of conspecific males, leading to reproduction. In the present study, moderate (30+) to very large data sets of phonotactic behaviour by female Acheta domesticus L., Gryllus bimaculatus DeGeer, Gryllus pennsylvanicus Burmeister and Gryllus veletis Alexander demonstrate substantially greater plasticity in the behavioural choices, as made by females of each species, for the syllable periods (SP) of model calling songs (CS) than has been previously described. Phonotactic choices by each species range from the very selective (i.e. responding to only one or two SPs) to very unselective (i.e. responding to all SPs presented). Some females that do not respond to all SPs prefer a range that includes either the longest or shortest SP tested, which fall outside the range of SPs produced by conspecific males. Old female A. domesticus and G. pennsylvanicus are more likely to be unselective for SPs than are young females. Each species includes females that do not respond to a particular SP when responding to CSs with longer and shorter SPs. The results suggest that the plasticity of phonotactic behaviour collectively exhibited by the females of each species does not ensure that choices of a male's CS effectively focus the female's phonotactic responses on CSs that represent the conspecific male. The phonotactic behaviour collectively exhibited by females of each species does not readily fit any of the models for selective processing by central auditory neurones that have been proposed to underlie phonotactic choice. [source] A Qualitative Investigation of Individual and Contextual Factors Associated With Vocational Recovery Among People With Serious Mental IllnessAMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 2 2010Erin C. Dunn Most people with serious mental illness (SMI) experience difficulty in fulfilling a vocational role, with many being unemployed or underemployed. Given the profound social and economic costs of this level of work impairment, researchers have investigated ways to enhance "vocational recovery," or the processes through which people with SMI regain their role as workers and reintegrate into the workforce. Using data collected from a larger qualitative study of 23 individuals who had progressed to an advanced stage of recovery from SMI, this study explored respondents' perspectives on employment and its relationship to their vocational recovery. Text passages describing employment were analyzed inductively by a diverse team of researchers. Seven themes were identified as being important in helping participants return to work or remain employed following the onset of a serious psychiatric disability: having the confidence to work, having the motivation to work, possessing work-related skills, assessing person,job fit, creating work opportunities, receiving social support, and having access to consumer-oriented programs and services. Implications of these findings on the development of interventions and policies to improve the vocational outcomes of people with SMI are discussed. [source] The 2010 American College of Rheumatology/European League Against Rheumatism classification criteria for rheumatoid arthritis: Phase 2 methodological reportARTHRITIS & RHEUMATISM, Issue 9 2010Tuhina Neogi Objective The American College of Rheumatology and the European League Against Rheumatism have developed new classification criteria for rheumatoid arthritis (RA). The aim of Phase 2 of the development process was to achieve expert consensus on the clinical and laboratory variables that should contribute to the final criteria set. Methods Twenty-four expert RA clinicians (12 from Europe and 12 from North America) participated in Phase 2. A consensus-based decision analysis approach was used to identify factors (and their relative weights) that influence the probability of "developing RA," complemented by data from the Phase 1 study. Patient case scenarios were used to identify and reach consensus on factors important in determining the probability of RA development. Decision analytic software was used to derive the relative weights for each of the factors and their categories, using choice-based conjoint analysis. Results The expert panel agreed that the new classification criteria should be applied to individuals with undifferentiated inflammatory arthritis in whom at least 1 joint is deemed by an expert assessor to be swollen, indicating definite synovitis. In this clinical setting, they identified 4 additional criteria as being important: number of joints involved and site of involvement, serologic abnormality, acute-phase response, and duration of symptoms in the involved joints. These criteria were consistent with those identified in the Phase 1 data-driven approach. Conclusion The consensus-based, decision analysis approach used in Phase 2 complemented the Phase 1 efforts. The 4 criteria and their relative weights form the basis of the final criteria set. [source] Plasma levels of opioid peptides after sunbed exposuresBRITISH JOURNAL OF DERMATOLOGY, Issue 6 2002T. Gambichler Summary Background Previous studies have indicated that solar and artificial ultraviolet (UV) radiation have a positive influence on psychological variables such as mood and emotional state. Circulating opioid peptides have been suggested as being important in this effect. Objectives To investigate in a controlled trial the influence of UVA radiation on opioid peptide levels. Methods We determined plasma levels of ,-endorphin immunoreactive material (IRM) and met-enkephalin in UV-exposed ( n = 35) and non-exposed ( n = 9) healthy volunteers. On the first day of the study, blood samples were taken from the volunteers (time A). UVA irradiation was subsequently administered with an air-conditioned tanning device. During the UV exposures the volunteers wore opaque goggles. Twenty minutes after UV exposure, blood samples were collected again (time B). Within the following 3 weeks the volunteers had a series of five UV exposures. On the last day of the study (24 h after the sixth UV exposure) blood samples were collected (time C). The cumulative UVA doses were 96 J cm ,2 for skin type II and 126 J cm ,2 for skin type III. The controls had no UV exposures. Plasma ,-endorphin IRM and met-enkephalin levels were determined using radioimmunoassays. Results At all times of blood collection (A, B, C), there were no significant differences in plasma levels of ,-endorphin IRM and met-enkephalin between UV-exposed and non-exposed volunteers ( P > 0·05). Conclusions UVA irradiation does not significantly elevate plasma levels of ,-endorphin IRM and met-enkephalin. Therefore we suggest that psychological benefits claimed to occur after UV exposure are unlikely to be mediated by the types of circulating opioid peptides measured in this study.
