Abstract Background  Increasingly, patient decision aids and values clarification methods (VCMs) are being developed to support patients in making preference‐sensitive health‐care decisions. Many VCMs encourage extensive deliberation about options, without solid theoretical or empirical evidence showing that deliberation is advantageous. Research suggests that simple, fast and frugal heuristic decision strategies sometimes result in better judgments and decisions. Durand et al. have developed two fast and frugal heuristic‐based VCMs. Objective  To critically analyse the suitability of the ‘take the best’ (TTB) and ‘tallying’ fast and frugal heuristics in the context of patient decision making. Strategy  Analysis of the structural similarities between the environments in which the TTB and tallying heuristics have been proven successful and the context of patient decision making and of the potential of these heuristic decision processes to support patient decision making. Conclusion  The specific nature of patient preference‐sensitive decision making does not seem to resemble environments in which the TTB and tallying heuristics have proven successful. Encouraging patients to consider less rather than more relevant information potentially even deteriorates their values clarification process. Values clarification methods promoting the use of more intuitive decision strategies may sometimes be more effective. Nevertheless, we strongly recommend further theoretical thinking about the expected value of such heuristics and of other more intuitive decision strategies in this context, as well as empirical assessments of the mechanisms by which inducing such decision strategies may impact the quality and outcome of values clarification.

Many health-related decisions require choosing between two options, each with risks and benefits. When presented with such tradeoffs, people often make choices that fail to align with scientific evidence or with their own values. This study tested whether risk communication and values clarification methods could help parents and guardians make evidence-based, values-congruent decisions about children's influenza vaccinations. In 2013-2014 we conducted an online 2×2 factorial experiment in which a diverse sample of U.S. parents and guardians (n = 407) were randomly assigned to view either standard information about influenza vaccines or risk communication using absolute and incremental risk formats. Participants were then either presented or not presented with an interactive values clarification interface with constrained sliders and dynamic visual feedback. Participants randomized to the risk communication condition combined with the values clarification interface were more likely to indicate intentions to vaccinate (β = 2.10, t(399) = 2.63, p < 0.01). The effect was particularly notable among participants who had previously demonstrated less interest in having their children vaccinated against influenza (β = -2.14, t(399) = -2.06, p < 0.05). When assessing vaccination status reported by participants who agreed to participate in a follow-up study six months later (n = 116), vaccination intentions significantly predicted vaccination status (OR = 1.66, 95%CI (1.13, 2.44), p < 0.05) and rates of informed choice (OR = 1.51, 95%CI (1.07, 2.13), p < 0.012), although there were no direct effects of experimental factors on vaccination rates. Qualitative analysis suggested that logistical barriers impeded immunization rates. Risk communication and values clarification methods may contribute to increased vaccination intentions, which may, in turn, predict vaccination status if logistical barriers are also addressed. © 2015 Society for Risk Analysis.

The pectin lyase gene pnl-zj5a from Aspergillus niger ZJ5 was identified and expressed in Pichia pastoris. PNL-ZJ5A was purified by ultrafiltration, anion exchange and gel chromatography. The Km and Vmax values determined using citrus pectin were 0.66 mg ml(-1) and 32.6 μmol min(-1) mg(-1) , respectively. PNL-ZJ5A exhibited optimal activity at 43°C and retained activity over 25-50°C. PNL-ZJ5A was optimally active at pH 5 and effective in apple juice clarification. Compared with controls, PNL-ZJ5A increased the fruit juice yield significantly. Furthermore, PNL-ZJ5A reduced the viscosity of apple juice by 38.8% and increased its transmittance by 86.3%. PNL-ZJ5A combined with a commercial pectin esterase resulted in higher juice volume. © 2014 The Society for Applied Microbiology.

Demaio, Christine M; Davis, Joanne L; Smith, Daniel W

2006-01-01

The "clarification session" has been implicated as an important component of the treatment of families affected by incest. On the basis of information presented in clinical literature, however, the specific nature of this intervention varies widely. This exploratory study examined the practices and attitudes regarding clarification sessions of select members of the Association for the Treatment of Sexual Abusers. Surveys were completed by 483 members. Results indicated that approximately 77% of respondents had experience in conducting clarification sessions. The top two reported reasons for conducting clarification sessions were for the perpetrator to assume all responsibility for the abuse and to decrease the level of self-blame of the victim. The majority of respondents concurred that several activities needed to occur prior to the clarification session, whereas less consensus was indicated for activities that were deemed essential during the clarification session. Respondents' practices, attitudes, and beliefs are discussed in terms of the current state of limited, empirically based knowledge in this area. Directions for future research are suggested.

OBJECTIVE: To evaluate the incremental effect of a graphic weigh-scale values clarification exercise to explicitly consider the personal importance of the benefits versus the risks in a woman's decision aid regarding postmenopausal hormone therapy. DESIGN: Randomized controlled trial. Intervention Decision aid including information on options, benefits and risks, and their probabilities either followed by: (1) a graphic weigh-scale values clarification exercise to explicitly consider the personal importance of each benefit and risk; or (2) a summary of the main benefits and risks to implicitly consider benefits versus the risks. SAMPLE: Two-hundred and one women aged 50-69 years from Ottawa, Canada, who had never used hormone therapy. OUTCOME: Perceived clarity of values, a sub-scale of the decisional conflict scale; congruence between personal values of benefits and risks (measured on 0-10 importance rating scale) and choices (accept, decline, unsure regarding preventive hormone therapy [HRT]) using discriminant function analysis. RESULTS: There were no statistically significant differences between interventions in perceived clarity of values and overall congruence between values and choices. Amongst those choosing HRT, there was a trend in those exposed to the graphic weigh-scale exercise to have better congruence between values and choices compared to implicit values clarification (P = 0.06). CONCLUSION: The use of the graphic weigh-scale exercise in a decision aid conveys no overall short-term benefit. Further study is needed to specifically determine effects in those changing the status quo and on the quality of patient-practitioner communication and persistence with decisions.

Clarifications regarding the use of model-fitting methods of kinetic analysis for determining the activation energy from a single non-isothermal curve.

PubMed

Sánchez-Jiménez, Pedro E; Pérez-Maqueda, Luis A; Perejón, Antonio; Criado, José M

2013-02-05

This paper provides some clarifications regarding the use of model-fitting methods of kinetic analysis for estimating the activation energy of a process, in response to some results recently published in Chemistry Central journal. The model fitting methods of Arrhenius and Savata are used to determine the activation energy of a single simulated curve. It is shown that most kinetic models correctly fit the data, each providing a different value for the activation energy. Therefore it is not really possible to determine the correct activation energy from a single non-isothermal curve. On the other hand, when a set of curves are recorded under different heating schedules are used, the correct kinetic parameters can be clearly discerned. Here, it is shown that the activation energy and the kinetic model cannot be unambiguously determined from a single experimental curve recorded under non isothermal conditions. Thus, the use of a set of curves recorded under different heating schedules is mandatory if model-fitting methods are employed.

This study analyses the effect of the crude enzymatic extract produced by Kluyveromyces marxianus (EEB) in the maceration and clarification of juice produced from Ives (Vitis labrusca) grapes compared to the commercial enzyme preparation Pectinex(®)Ultra Color (PEC). Treatments were conducted with a total pectinolytic activity of 1 U/mL of fruit juice, at 40 °C, for 60 min. After the enzymatic treatment, the juices were evaluated with respect to yield, viscosity, and degree of clarification, as well as the effect of the enzymes on polyphenol concentration, anthocyanins, and juice color. The results showed that both EEB and PEC increase yield, reduce viscosity and contribute to the clarification of grape juice. After enzyme treatment with the EEB preparation, the extraction yield increased 28.02 % and decreased 50.70 % in viscosity during the maceration of the pulp. During the juice production process clarification increased 11.91 %. With PEC, higher values for these parameters: 42.36, 63.20, and 26.81 % respectively, were achieved. The addition of EEB resulted in grape juice with better color intensity and extraction of phenolic compounds and anthocyanins. Considering all comparison criteria, the enzymatic extract of K. marxianus NRRL-Y-7571 can potentially be used in the production of juice.

Use of thermostable enzyme from bacilli for industrial application is significant. This research aimed to isolate thermophilic pectinolytic bacteria from orange peel and vegetable waste which produced thermostable polygalacturonase, to investigate the polygalacturonase ability in clarifying keprok Garut orange juice, and to characterize polygalacturonase based on pH optimum, temperature optimum, enzyme stability, enzyme kinetics KM, and Vmax. Obtained, 14 isolates that further selected to 4 best isolates based on highest polygalacturonase activity and keprok Garut orange juice clarification ability. Four selected enzyme isolates were AR 2, AR 4, KK 4, and KK 5 had ability to increase juice transmittance, decrease juice viscosity and also reduce total soluble solid. Furthermore 4 selected isolates were partially purified by ammonium sulphate precipitation and dialysis method. Four partially purified enzymes were known that enzyme character of AR 2 optimum at pH 6; AR 4 optimum at pH 5.5; KK 4 optimum at pH 6; and KK 5 optimum at pH 4.5. Four enzymes were optimum at temperature 60°C thus stable at temperature 50-60°C, this characteristic indicate that enzymes were thermostable. AR 2 showed active activity stable at pH 4-7; AR 4 showed active activity stable at pH 6-7; KK 4 showed active activity stable at pH 4-6; however KK 5 stable at pH 4-5. Enzyme AR 2 and KK 4 was getting inactive at pH 11, thus AR 4 and KK 5 inactive at pH 12. KM value of AR 2, AR 4, KK 4, and KK 5 was 0.0959; 0.0974; 0.0966; and 0.178 mg/ml respectively. Vmax of AR 2, AR 4, KK 4, and KK 5 was 0.0203; 0.0202; 0.0185; and 0.0229 U/ml respectively. Enzyme AR 2 was the most compatible enzyme to be applied in keprok Garut orange juice clarification for it had the lowest KM value.

Process cost and facility considerations in the selection of primary cell culture clarification technology.

The bioreactor volume delineating the selection of primary clarification technology is not always easily defined. Development of a commercial scale process for the manufacture of therapeutic proteins requires scale-up from a few liters to thousands of liters. While the separation techniques used for protein purification are largely conserved across scales, the separation techniques for primary cell culture clarification vary with scale. Process models were developed to compare monoclonal antibody production costs using two cell culture clarification technologies. One process model was created for cell culture clarification by disc stack centrifugation with depth filtration. A second process model was created for clarification by multi-stage depth filtration. Analyses were performed to examine the influence of bioreactor volume, product titer, depth filter capacity, and facility utilization on overall operating costs. At bioreactor volumes <1,000 L, clarification using multi-stage depth filtration offers cost savings compared to clarification using centrifugation. For bioreactor volumes >5,000 L, clarification using centrifugation followed by depth filtration offers significant cost savings. For bioreactor volumes of ∼ 2,000 L, clarification costs are similar between depth filtration and centrifugation. At this scale, factors including facility utilization, available capital, ease of process development, implementation timelines, and process performance characterization play an important role in clarification technology selection. In the case study presented, a multi-product facility selected multi-stage depth filtration for cell culture clarification at the 500 and 2,000 L scales of operation. Facility implementation timelines, process development activities, equipment commissioning and validation, scale-up effects, and process robustness are examined. © 2013 American Institute of Chemical Engineers.

The effect of a required third-year family medicine clerkship on medical students' attitudes: value indoctrination and value clarification.

PubMed

Senf, J H; Campos-Outcalt, D

1995-02-01

The effect of a required six-week third-year family medicine clerkship was examined within a framework of professional socialization. Socialization was considered to consist of an institutional process, i.e., value indoctrination, and a learner process, i.e., value clarification. Pre- and postclerkship data from 1,095 students (classes of 1981-1993) at the University of Arizona College of Medicine were analyzed. In addition, specialty match data were obtained. Factor analysis of 19 items on the pre- and postclerkship questionnaires was used to derive four scales measuring attitudes related to family medicine. The students were first grouped into four groups: those who preferred family medicine before and after the clerkship, those who preferred other specialties both times, those who switched to family medicine, and those who switched away from family medicine. Then the students were grouped into eight groups by dividing each of the specialty-preference groups into two sections: those who matched to family medicine and those who did not. Statistical comparisons involved the use of the t and F statistics. Usable data were available for a maximum of 997 students (91%). The students' attitudes about family medicine changed during the clerkship to become more consistent with their postclerkship specialty preferences. In addition, more students preferred family medicine after the clerkship than before it. When each group was further divided into those matching and not matching into family medicine, no significant difference in attitudes was found between those matching and those not matching. These results reflect both a value clarification process and a value indoctrination effect. The discrepancy between postclerkship specialty preferences and later match data indicates that the indoctrination effect and clarification process continue into the fourth year.

To present theory that illustrates the relevance of ethics for lifestyle counselling in patient-centred general practice, and to illustrate the theory by a qualitative study exploring how doctors may obstruct or enhance the possibilities for ethical dialogue. The theoretical part is based on theory of common morality and Habermas' communication theory. The empirical study consists of 12 consultations concerning lifestyle changes, followed by interviews of doctors and patients. Identification of two contrasting consultations holding much and little ethical dialogue, "translation" into speech acts, and interpretation of speech acts and interviews guided by theory. General advice obstructed possibilities for ethical clarification and patient-centredness. Ethical clarification was asked for, and was enhanced by the doctor using communication techniques such as interpretation, summarization, and exploration of the objective, subjective and social dimensions of the patients' lifeworlds. However, to produce concrete good decisions an additional reflection over possibilities and obstacles in the patient's lifeworld is necessary. Consultations concerning lifestyle changes hold opportunities for ethical clarification and reflection which may create decisions rooted in the patient's everyday life. The study suggests that GPs should encourage active reflection and deliberation on values and norms in consultations concerning lifestyle changes. Copyright © 2010 Elsevier Ireland Ltd.

Values education: a new direction for medical education.

PubMed Central

Grundstein-Amado, R

1995-01-01

This paper suggests that medical education should redirect resources to values education, specifically developing new strategies to improve the process of clarification of values. The author suggests using the values journal method which is based on a systematic record of students' personal value systems reflected in their stories and life experience; and on their responses to case presentation. Generating a personal values journal helps students define who they are, what their social and professional roles are, what their expectations are and where they are going. Keeping values journals promotes students' decision-making capacity, and equips them with the necessary skills to teach their future patients how to generate their own value systems. The development of a well defined values journal is a preparatory stage for active participation in clinical conferences or group discussion, and for effective communal dialogue among the group's members.

Wistoft, Karen

2009-09-01

Individual and social values are increasingly important in health education. This article examines how health educators in Greenland and Denmark engage in value clarification as part of their educational practices. It presents the results of a study of health professionals in a variety of settings, focusing in particular on how development work and experimentation can strengthen their pedagogical competences. The study focuses on belief, reasoning, interpretation and reflection, rather than routines, skills, or ethical rules, and takes a participatory approach that oscillates between dialogical and qualitative empirical methodologies. It observes pedagogical practice in selected settings in Greenland and the municipality of Copenhagen. Within the framework provided by four discourses that appear to organize communication about health, it shows how values became important to the progress of two research-based development projects. On this basis, the article argues that health education can be effectively grounded in the values, perceptions, and experiences of a given population, while being guided by the health educators' biomedical knowledge and educational values.

Biological macromolecules are primarily composed of complex polysaccharides that strengthen microbial growth for the production of industrially relevant enzymes. The presence of polysaccharides in the form of the disrupted cell wall and cell materials are among major challenges in the fruit juice industry. The breakdown of such biological macromolecules including cellulose and pectin is vital for the juices processing. In this background, pectinolytic enzymes including polygalacturonase (PG), pectin lyase (PL), and pectin methylesterase (PME) were isolated from Aspergillus ornatus, statistically optimized and purified via ammonium sulfate fractionation (ASF), dialysis, and Sephadex G-100 gel permeation chromatography. After passing through Sephadex G-100 column, PG, PL, and PME were 2.60-fold, 3.30-fold, and 4.52-fold purified with specific activities of 475.2U/mg, 557.1U/mg, and 205.7U/mg. The active PG, PL, and PME, each separately, were surface immobilized using various concentrations of chitosan and dextran polyaldehyde as a macromolecular crosslinking agent. Prior to exploit for juice clarification purposes, various parameters including pH, thermal and Michaelis-Menten kinetic constants of purified and chitosan-immobilized fractions were investigated. A considerable improvement in the pH and thermal profiles was recorded after immobilization. However, the negligible difference between the K m and V max values of purified free and chitosan-immobilized fractions revealed that the conformational flexibility of pectinolytics was retained as such. A significant color and turbidity reductions were recorded after 60min treatment with CTS-PG, followed by CTS-PME, and CTS-PL. It can be concluded that the clarification of apples, mango, peach, and apricot juices was greatly affected by CTS-PG, CTS-PME, and CTS-PL treatments rendering them as potential candidatures for food industry applications.

Clarity of fruit juices is desirable to maintain an aesthetically pleasing quality and international standards. The most commonly used enzymes in juice industries are pectinases. A partially-purified pectinmethylesterase from tomato was entrapped in calcium alginate beads and used for juice clarification. The activity yield was maximum at 1 % (w/v) CaCl2 and 2.5 % (w/v) alginate. The immobilized enzyme retained ~55 % of its initial activity (5.7 × 10(-2) units) after more than ten successive batch reactions. The Km, pH and temperature optima were increased after immobilization. The most effective clarification of fruit juice (%T620 ~60 %) by the immobilized enzyme was at 4 °C with a holding time of 20 min. The viscosity dropped by 56 % and the filterability increased by 260 %. The juice remains clear after 2 months of storage at 4 °C.

Abstract Objective  To report on the initial testing of a values clarification exercise utilizing a jewellery box within a computerized patient decision aid (CPtDA) designed to assist women in making a surgical breast cancer treatment decision. Design  Pre‐post design, with patients interviewed after diagnosis, and then after completing the CPtDA sometime later at their preoperative visit. Sample  Fifty‐one female patients, who are low literate and naïve computer users, newly diagnosed with early stage breast cancer from two urban public hospitals. Intervention  A computerized decision aid that combines entertainment‐education (edutainment) with enhanced (factual) content. An interactive jewellery box is featured to assist women in: (1) recording and reflecting over issues of concern with possible treatments, (2) deliberating over surgery decision, and (3) communicating with physician and significant others. Outcomes  Patients’ use of the jewellery box to store issues during completion of the CPtDA, and perceived clarity of values in making a treatment decision, as measured by a low literacy version of the Decisional Conflict Scale (DCS). Results  Over half of the participants utilized the jewellery box to store issues they found concerning about the treatments. On average, users flagged over 13 issues of concern with the treatments. Scores on the DCS Uncertainty and Feeling Unclear about Values subscales were lower after the intervention compared to before the decision was made. Conclusions  A values clarification exercise using an interactive jewellery box may be a promising method for promoting informed treatment decision making by low literacy breast cancer patients.

Improvement of activity, thermo-stability and fruit juice clarification characteristics of fungal exo-polygalacturonase.

PubMed

Amin, Faiza; Bhatti, Haq Nawaz; Bilal, Muhammad; Asgher, Muhammad

2017-02-01

An extracellular exo-polygalacturonase (exo-PG) from Penicillium notatum was immobilized in sodium-alginate matrix through two different protocols, viz. covalent bonding and adsorption to enhance its catalytic activity, thermal stability and life-time properties for industrial applications. Covalent immobilization was more efficient in terms of high relative activity (45.89%) and immobilization yield (71.6%) as compared to adsorption. Immobilized exo-PG derivatives displayed maximum activities at pH 5.5 and 55°C as compared to free enzyme which showed its optimum activity at pH 6.0 and 50°C. The affinity of enzyme towards its substrate (K m(app) ) was reduced after immobilization and V max of covalently immobilized exo-PG decreased to 66.7% while the V max value of adsorbed enzyme increased up to 150% as compared to free counterpart. Both immobilization techniques greatly enhanced the thermal stability profile of the enzyme. At 60°C, immobilized exo-PGs retained more than 90% of their residual activities after 60min of heating, while free enzyme did not show any activity at the same temperature. Thermodynamic properties (i.e., Ea, ΔH*, ΔS*and ΔG*) of the free and immobilized enzymes were also investigated. Sodium-alginate covalently immobilized and adsorbed enzymes showed excellent recycling efficiencies and retained 50.0% and 41.0% of original activities, respectively after seven consecutive batch reactions. Moreover, the immobilized enzymes treatment achieved promising results in turbidity and viscosity reduction as well as clarity amelioration in various fruit juices. Altogether catalytic, thermo-stability and fruit juices clarification characteristics of the immobilized ex-PGs suggest a high potential for biotechnological exploitability.

Introduction: Clarification of the relationship between external stimuli and brain response has been an important topic in neuroscience and brain rehabilitation. In the current study, using functional near infrared spectroscopy (fNIRS), we attempted to investigate cortical activation patterns generated during execution of a rehabilitation robotic hand. Methods: Ten normal subjects were recruited for this study. Passive movements of the right fingers were performed using a rehabilitation robotic hand at a frequency of 0.5 Hz. We measured values of oxy-hemoglobin (HbO), deoxy-hemoglobin (HbR) and total-hemoglobin (HbT) in five regions of interest: the primary sensory-motor cortex (SM1), hand somatotopy of the contralateral SM1, supplementary motor area (SMA), premotor cortex (PMC), and prefrontal cortex (PFC). Results: HbO and HbT values indicated significant activation in the left SM1, left SMA, left PMC, and left PFC during execution of the rehabilitation robotic hand (uncorrected, p < 0.01). By contrast, HbR value indicated significant activation only in the hand somatotopic area of the left SM1 (uncorrected, p < 0.01). Conclusions: Our results appear to indicate that execution of the rehabilitation robotic hand could induce cortical activation. PMID:24570660

Health policy in a new key: setting democratic priorities.

PubMed

Jennings, B

1993-01-01

Health policy in the United States is entering an era in which explicitly value-based allocation decisions require direct attention. Policies concerning access to care, financing, and utilization management will necessarily have redistributive effects. For these policies to command social legitimacy and political support, some consensus will have to emerge around the values and ideals justifying these policies. This article addresses the problems of conceptual clarification and democratic process raised by the prospect of an explicitly value-based allocation policy. It offers a conceptual matrix distinguishing the scope of the issue of allocation in health care. Drawing on the activities of community health decisions projects in several states, it also offers suggestions about building a participatory and educational process at the grassroots level that might lead to a democratic consensus suitable for guiding policy choice.

The present work is focused on efficient immobilization of polygalacturonase on polyethylene matrix, followed by its application in apple juice clarification. Immobilization of polygalacturonase on activated polyethylene and its use in apple juice clarification was not reported so far. Aspergillus niger Van Tieghem (MTCC 3323) produced polygalacturonase when grown in modified Riviere's medium containing pectin as single carbon source by fed-batch culture. The enzyme was precipitated with ethanol and purified by gel filtration chromatography (Sephacryl S-100) and immobilized onto glutaraldehyde-activated polyethylene. The method is very simple and time saving for enzyme immobilization. Various characteristics of immobilized enzyme such as optimum reaction temperature and pH, temperature and pH stability, binding kinetics, efficiency of binding, reusability and metal ion effect on immobilized enzymes were evaluated in comparison to the free enzyme. Both the free and immobilized enzyme showed maximum activity at a temperature of 45 degrees C and pH 4.8. Maximum binding efficiency was 38%. The immobilized enzyme was reusable for 3 cycles with 50% loss of activity after the third cycle. Twenty-four U of immobilized enzyme at 45 degrees C and 1 h incubation time increased the transmittance of the apple juice by about 55% at 650 nm. The immobilized enzyme can be of industrial advantage in terms of sturdiness, availability, inertness, low price, reusability and temperature stability.

Optimization of substrate concentration, time of incubation and temperature for crude pectinase production from A. niger was carried out using Bhimkol banana (Musa balbisiana) peel as substrate. The crude pectinase produced was partially purified using ethanol and effectiveness of crude and partially purified pectinase was studied for banana juice clarification. The optimum substrate concentration, incubation time and temperature of incubation were 8.07 %, 65.82 h and 32.37 °C respectively, and the polygalacturonase (PG) activity achieved was 6.6 U/ml for crude pectinase. The partially purified enzyme showed more than 3 times of polygalacturonase activity as compared to the crude enzyme. The SDS-PAGE profile showed that the molecular weight of proteins present in the different pectinases varied from 34 to 42 kDa. The study further revealed that highest clarification was achieved when raw banana juice was incubated for 60 min with 2 % concentration of partially purified pectinase and the absorbance obtained was 0.10.

In central Tunisia, many upper Eocene outcrops supply smectitic claystone which are characterized by several analytical techniques (calcimetry, XRD, SediGraph, chemical analysis, surface area, etc.). Beidellite is the main mineral detected by the XRD method. Representative raw samples M1, taken from Henchir Souar (Zaghouan, Tunisia), were acid activated in order to improve their physicochemical properties. This study consists in optimizing the activation conditions with HCl 3 N by varying the following parameters: time (2, 4, and 6 h) and temperature (25, 50, 75, and 90 °C). The characterization by XRD and chemical analysis was carried out on the samples (M1, activated for 2 and 6 h at 75 °C), showing a structural modification of the clay by reduction of intensity reflection 001 order of smectite and dissolution of metal ions (Al 3+ , Fe 3+ , and Mg 2+ ) from clay structure. Optimum condition for soybean oil clarification is obtained using a variety of amount raw clays (0.5, 0.75, and 1%). Thus, the best clarification yield is given at 0.75% of clay, showing a capacity of about 55%. Various forms of activated materials were used with a 75% proportion to leach soybean oil. Results were compared with commercial bentonite (Tonsil) having surface area (378 m 2 /g). The activated sample M1 during 4 h at 75 °C possesses a decolorizing capacity of about 85% greater than the oil treated by Tonsil in laboratory (58%).

The effects of a clarifying process using pectinases and chitosan on the physicochemical characteristics, antioxidant capacity and quality attributes of açaí fruit (Euterpe oleracea Mart.) juice were evaluated. Clarification of acaí pulp resulted (P ≤ 0.05) in a 50 % loss of total anthocyanin (4.2730 mg/100 mL) and 29 % reduction in antioxidant capacity (33.60 μM FeSO4/g). A high association (P ≤ 0.05) was found between the decrease of antioxidant capacity and total anthocyanin loss. The use of pectinases associated with chitosan as an aid for clarification of açaí juice proved to be highly effective and resulted in a clear juice with a brighter purple to red color that was free of lipids, insoluble solids, and others substances that cause hazes. The obtained clarified açaí juice is a genuinely high-value anthocyanin-rich product that could be used as colorant and functional ingredient to fruit juices and soft drinks.

Polygalacturonase (PG) degrades pectin into D-galacturonic acid monomers and is used widely in food industry especially for juice clarification. In the present study,. fermentation conditions for polygalacturonase production by Asgergillus niger NAIMCCF-02958, using mango peel as substrate, were optimized using the 2(3) factorial design with central composite rotatable experimental design (CCRD) of response surface methodology (RSM). The maximum PG activity 723.66 U g(-1) was achieved under pH 4.0, temperature 30 degrees C and 2% inoculum by response surface curve. The experimental value of PG activity wkas higher 607.65 U g(-1) than the predicted value 511.75 U g(-1). Under the proposed optimized conditions, the determination coefficient (R2) was equal to 0.66 indicating that the model could explain 66% of the total variation as well as establish the relationship between the variables and the responses. ANOVA analysis and the three dimensional plots also confirmed interactions among the parameters.

2017-08-01

This work was aimed to study the clarification efficiency of natural decantation in settling tank on virgin olive oil obtained from a two-ways continuous process. For this purpose, the impurities content of the virgin olive oil were monitored during settling process in settling tank at two different depths. Efficiency of purging system was determined for two days. The experiments were performed at industrial scale during three crop years. During the first minutes of settling was observed an ascent of the smaller organic particles of the oil. Then, most of the virgin olive oil impurities were settled at 300 min, independently of the initial content of virgin olive oil. Finally, oil decantation showed slower rate. Higher clarification values were obtained for those decanter oils with higher impurities content, achieving clarification percentages between of 62.69 and 95.91% at 48 h of settling. The highest settling efficiency was observed for those decanter oils with initial higher impurities content. The purging system used in the settling tanks was not able to remove the most of settled impurities since a considerable amount of the impurities remained in the tank after 48 h, between 13.6 and 71.41% for the studied oils. In the tank purges was observed important oil losses. Therefore, decantation was not an efficient system for oil clarification since its settling capacity varied depending on the initial impurities content and due to the settled impurities can not be removed fully by purging system.

In this proof-of-concept study, we sought to evaluate whether a value clarification tool enabling patients to view a set of rheumatoid arthritis (RA) treatment preference phenotypes could be used to support shared decision-making (SDM) at the point-of-care. We conducted a pre-post test study. All English-speaking RA patients presenting to their scheduled outpatient visits were asked to participate. Visits for patients with active RA were transcribed. SDM components were measured using a quantitative coding scheme based on an established model of SDM. Forty-six visits were included in the pre-test and 40 in the post-test phase. Providers offered more DMARDs (two or more) in the post-test visits (60%) compared to the pre-test visits (47.8%). Overall, more patients vocalized their values and/or preferences in the post-test visits compared to the pre-test visits for treatment escalation decisions including choice of one new DMARD (90.9% versus 56.3%), two or more new DMARDs (95.8% versus 86.4%), as well as prednisone (87.5% versus 66.7%). Providers were also more likely to base their recommendations on patients' values and/or preferences in the post-test (100% of six visits) than pre-test (64.3% of 14 visits) phase during visits in which a recommendation was made. The average (SD) length of the visit was 29.9 (11.6) minutes and 25.1 (10.7) minutes in the pre- and post-test phases respectively. This study provides an early indication that a value clarification tool allowing patients to consider a set of preference phenotypes can support SDM at the point-of-care without extending visit time.

Azevedo, A; Etchepare, R; Rubio, J

2017-05-01

Raw water clarification by flotation was studied by injecting air into a centrifugal multiphase pump to generate microbubbles (MBs) and nanobubbles (NBs). Measurements of gas dispersion parameters were performed and optimal conditions were obtained using a pump pressure of 4 bar. Values showed a bubble Sauter diameter of 75 μm, an air holdup of 1.2%, a bubble surface area flux of 34 s -1 and an NB concentration of 1 × 10 8 NBs mL -1 (measuring 220 nm). Then, a study compared flotation with bubbles formed with the multiphase pump (F-MP) to lamellar settling at the clarification stage of a water treatment plant (WTP), in Brazil. The F-MP showed a higher separation efficiency at high hydraulic loads (9-15 m h -1 ), even without the use of a polymer, reaching 2 NTU (10-25 NTU raw water feed), which was much lower than the technical goal of the WTP (5 NTU). The results and the technical aspects are discussed, and it is concluded that the employment of MBs and NBs with pumps widens new research lines and applications in modern flotation.

Effect of pectin methylesterase on carrot (Daucus carota) juice cloud stability.

PubMed

Schultz, Alison K; Anthon, Gordon E; Dungan, Stephanie R; Barrett, Diane M

2014-02-05

To determine the effect of residual enzyme activity on carrot juice cloud, 0 to 1 U/g pectin methylesterase (PME) was added to pasteurized carrot juice. Cloud stability and particle diameters were measured to quantify juice cloud stability and clarification for 56 days of storage. All levels of PME addition resulted in clarification; higher amounts had a modest effect in causing more rapid clarification, due to a faster increase in particle size. The cloud initially exhibited a trimodal distribution of particle sizes. For enzyme-containing samples, particles in the smallest-sized mode initially aggregated to merge with the second peak over 5-10 days. This larger population then continued to aggregate more slowly over longer times. This observation of a more rapid destabilization process initially, followed by slower subsequent changes in the cloud, was also manifested in measurements of sedimentation extent and in turbidity tests. Optical microscopy showed that aggregation created elongated, fractal particle structures over time.

A magnetic tri-enzyme nanobiocatalyst for fruit juice clarification.

Sojitra, Uttam V; Nadar, Shamraja S; Rathod, Virendra K

2016-12-15

The major complications in fruit juice quality improvement are the presence of polysaccharides components in the form of disrupted fruit cell wall and cell materials. Hence, breakdown of cellulose along with pectin and starch is important for the juice processing. In this context, magnetic tri-enzyme nanobiocatalyst was prepared by simultaneously co-immobilizing three enzymes; α-amylase, pectinase and cellulase onto amino-functionalized magnetic nanoparticle by 60mM glutaraldehyde concentration with 10h cross-linking time for one pot juice clarification. The prepared nanobiocatalyst was characterized by FT-IR, SEM and XRD. The thermal (50-70°C) and pH (3-6) stability studies indicated more than two folds increment in half-life and enhanced tolerance to lower pH. The immobilized enzymes retained up to 75% of residual activity even after eight consecutive cycles of reuse. Finally, the clarification of apple, grapes and pineapple juices using magnetic tri-enzyme showed 41%, 46% and 53% respective reduction in turbidity till 150min treatment.

Self-care among older people living with chronic conditions.

PubMed

LeBlanc, Raeann G; Jacelon, Cynthia S

2018-03-24

The aim of this study was to clarify the concept of self-care among older people living with chronic health conditions. This concept clarification will assist nurses in addressing self-care among older people through research, policy and practice in offering an expanded conceptual model. Several policy influences over the past decade directly relate to the increased importance and economic necessity to require self-directed care for older people living with chronic health conditions to maintain their care at home in the community. A selective review of literature on the concept of self-care included 31 sources. The Norris Concept Clarification method (1982) was used for clarification. The phenomenon is described historically according to its antecedents, attributes and consequences. A proposed definition is provided based on the clarification of this concept. A conceptual model is presented through an ecological framework. Self-care among older people living with chronic conditions is multidimensional and has multilevel influences (individual, community, system levels) and is mediated by the contexts and processes of ageing. Self-care originates along one's life course and is learned. Self-care responses are based on care needs when living with chronic health conditions. Self-care is an individual capacity, disposition and activity older people manifest in living with multiple chronic conditions. These features (capacity, disposition, action) influence one another and are hierarchical and continuous. Research, practice and policies that promote self-care among older people can focus on these features to improve health outcomes and promote new models of care consistent with personal development and chronic care needs in older age. This concept clarification can offer a model to support self-care among older people living with chronic conditions. © 2018 John Wiley & Sons Ltd.

South Africa's abortion values clarification workshops — an opportunity to deepen democratic communication missed.

PubMed

Vincent, Louise

2011-01-01

A rich literature exists on local democracy and participation in South Africa. While the importance of participation is routinely built into the rhetoric of government, debate has increasingly focused on the dysfunctionality of participatory mechanisms and institutions in post-apartheid South Africa. Processes aimed ostensibly at empowering citizens, act in practice as instruments of social control, disempowerment and cooptation. The present article contributes to these debates by way of a critique of the approach used by the South African state, in partnership with the non-governmental sector, in what are called abortion "values clarification" (VC) workshops. This article examines the workshop materials, methodology and pedagogical tools employed in South African abortion VC workshops which emanate from the organization Ipas — a global body working to enhance women's sexual and reproductive rights and to reduce abortion-related deaths and injuries. VC workshops represent an instance of a more general trend in which participation is seen as a tool for generating legitimacy and "buy-in" for central state directives rather than as a means for genuinely deepening democratic communication. The manipulation of participation by elites may serve as a means to achieve socially desirable goals in the short term but the long-term outlook for a vibrant democracy invigorated by a knowledgeable, active and engaged citizenry that is accustomed to being required to exercise careful reflection and to its views being respected, is undermined. Alternative models of democratic communication, because they are based on the important democratic principles of inclusivity and equality, have the potential both to be more legitimate and more effective in overcoming difficult social challenges in ways that promote justice.

1993-01-01

The Family Planning Association of Trinidad and Tobago (FPATT) has decided that integration of the concept of sexual and reproductive health into regular family planning activities is the best way to increase the contraceptive prevalence rate. A more holistic approach to service provision is being developed. On the basis of survey findings that early sexual activity, low contraceptive use, and limited knowledge are widespread among young people, this population group has been selected as a focus. FPATT has asked for a TT$1 million subsidy to intensify sex education programs in the schools. Issues discussed include human sexuality, values clarification, relationships, problems affecting teenagers, parenting, rape and incest, and family planning. FPATT also conducts training sessions for teachers and parents. Since young people tend to respond best to peers, peer counseling is emphasized. Education is also offered at large industrial sites, private homes in small communities, and government health centers.

In the present study, we prepared two different magnetic biocatalysts of pectinase and cellulase: carrier-free magnetic CLEAs (CLEA-MP*) and immobilization on glutaraldehyde-activated magnetite (Enz-Glu-MP*). The biocatalysts were compared to their magnetic properties, immobilization parameters, stability and grape juice clarification. Enz-Glu-MP* presented higher magnetic properties than CLEA-MP*, whereas this presented higher surface area and pore volume. The K M of the enzyme immobilized on Enz-Glu-MP* was 25.65mM, lower in comparison to the CLEA-MP* (33.83mM). On the other hand, CLEA-MP* was the most active and stable biocatalyst, presenting higher recovered activity (33.4% of cellulase), higher thermal stability (2.39 stabilization factor) and improved reusability (8cycles). The integration of magnetic technology with enzymatic immobilization emerges as a possibility to increase the recover and reuse of biocatalysts for application in juice technology.

Tannase is an enzyme that hydrolyzes esters and lateral bonds of tannins, such as tannic acid, releasing glucose and gallic acid and stands out in the clarification of wines and juices. Fungi of the genera Aspergillus and Penicillium are excellent producers of this enzyme. The search for fungi that produce high levels of tannase as well as new substrates for the enzyme production by the SSF is required. The objectives of this study were to evaluate the production of tannase by Aspergillus and Penicillium species through SSF using leaves and agroindustrial waste barbados cherry and mangaba fruit as substrate, select the best producer, optimize production, characterize the crude enzyme extract, and apply it the clarification of grape juice. Selecting the best producer was performed by planning Placket-Burman and RSM. P. montanense showed highest activity with 41.64 U/mL after 72 h of fermentation residue using barbados cherry, with 3.5% tannic acid and 70% moisture. The enzyme showed the highest activity at pH 9.0 and 50°C. The tannase of P. montanense was stable over a wide pH range and temperature and, when applied to grape juice, showed higher efficiency by reducing 46% of the tannin content after incubation 120 m.

Vaccines are derived from a variety of sources including tissue extracts, bacterial cells, virus particles, recombinant mammalian, yeast and insect cell produced proteins and nucleic acids. The most common method of vaccine production is based on an initial fermentation process followed by purification. Production of vaccines is a complex process involving many different steps and processes. Selection of the appropriate purification method is critical to achieving desired purity of the final product. Clarification of vaccines is a critical step that strongly impacts product recovery and subsequent downstream purification. There are several technologies that can be applied for vaccine clarification. Selection of a harvesting method and equipment depends on the type of cells, product being harvested, and properties of the process fluids. These techniques include membrane filtration (microfiltration, tangential-flow filtration), centrifugation, and depth filtration (normal flow filtration). Historically vaccine harvest clarification was usually achieved by centrifugation followed by depth filtration. Recently membrane based technologies have gained prominence in vaccine clarification. The increasing use of single-use technologies in upstream processes necessitated a shift in harvest strategies. This review offers a comprehensive view on different membrane based technologies and their application in vaccine clarification, outlines the challenges involved and presents the current state of best practices in the clarification of vaccines.

Drinking water is currently a scarce world resource, the preparation of which requires complex treatments that include clarification of suspended particles and disinfection. Seed extracts of Moringa oleifera Lam., a tropical tree, have been proposed as an environment-friendly alternative, due to their traditional use for the clarification of drinking water. However, the precise nature of the active components of the extract and whether they may be produced in recombinant form are unknown. Here we show that recombinant or synthetic forms of a cationic seed polypeptide mediate efficient sedimentation of suspended mineral particles and bacteria. Unexpectedly, the polypeptide was also found to possesses a bactericidal activity capable of disinfecting heavily contaminated water. Furthermore, the polypeptide has been shown to efficiently kill several pathogenic bacteria, including antibiotic-resistant isolates of Staphylococcus, Streptococcus, and Legionella species. Thus, this polypeptide displays the unprecedented feature of combining water purification and disinfectant properties. Identification of an active principle derived from the seed extracts points to a range of potential for drinking water treatment or skin and mucosal disinfection in clinical settings.

Genetic, physiologic and ecogeographic factors contributing to variation in Homo sapiens: Homo floresiensis reconsidered.

PubMed

Richards, Gary D

2006-11-01

A new species, Homo floresiensis, was recently named for Pleistocene hominid remains on Flores, Indonesia. Significant controversy has arisen regarding this species. To address controversial issues and refocus investigations, I examine the affinities of these remains with Homo sapiens. Clarification of problematic issues is sought through an integration of genetic and physiological data on brain ontogeny and evolution. Clarification of the taxonomic value of various 'primitive' traits is possible given these data. Based on this evidence and using a H. sapiens morphological template, models are developed to account for the combination of features displayed in the Flores fossils. Given this overview, I find substantial support for the hypothesis that the remains represent a variant of H. sapiens possessing a combined growth hormone-insulin-like growth factor I axis modification and mutation of the MCPH gene family. Further work will be required to determine the extent to which this variant characterized the population.

The influence of clarification and threats on life situation: patients’ experiences 1 year after TSCI

Introduction: The study was conducted at the Spinal Cord Injury Centre of Western Denmark (VCR). The aim of the study was to explore patients’ experiences following traumatic spinal cord injury and to identify characteristics of positive versus negative life situation 1 year post discharge from hospital rehabilitation. This was a qualitative study conducted using inductive content analysis. Case Presentation: In this qualitative study seven patients were interviewed one year after discharge from initial rehabilitation at the VCR. The interviews were analysed using inductive content analysis. Discussion: We found that two categories condensed the patients’ experiences of their life situation 1 year post discharge: ‘clarification in relation to overall life situation’ and ‘threat to core competences’. The transversal analysis across the derived categories identified different combinations of clarification and threats to core competences explaining the patients’ experiences: high degree of clarification combined with low degree of threat to core competences was indicative of positive life situation. Also, positive life situation was seen when a high degree of clarification compensated for high degree of threats on core competencies. In contrast, an overall stressful and negative life situation was influenced by poor clarification combined with a high degree of threat to core competences. However, when core competences can be transformed into new skills, threats were manageable. This study revealed that clarification related to overall life situation in combination with threat to core competences may explain traumatic spinal cord injury patients’ overall life situation 1 year post discharge. An appropriate balance characterises a positive life situation. There might be a need to pay attention to patients who are challenged by low degree of clarification and high degree of threats on core competencies 1 year post discharge as this may influence the life situation negatively.

2016-10-01

An extracellular endo-polygalacturonase (PGase) was purified, after a single purification step, from the constitutive and hyperpectinolytic CT1 mutant of Penicillium occitanis. This enzyme named PG2 has a molecular weight of 42kDa. It was optimally active at 35°C and pH6 with more than 85% of activity at pH7 in contrast to the majority of fungal PGase, generally acting at 50°C and pH5. The specific activity obtained was among the highest ones, 31397.26U/mg. The PGase activity increased with the decrease of the degree of methylation (DM) of pectin, but it was also able to degrade the highly methyl-esterified substrates, 70% (DM) and 90% (DM), with almost 80% and 40% of residual activity respectively. Interestingly, PG2 is completely inhibited by DEPC, suggesting the implication of a Histidine residue in the active site. The sequencing of P. occitanis whole genome allowed us to identify the pga2 gene encoding PG2 and to localize the His residue, target of DEPC, while it was absent in the PG1 that resisted to DEPC. Besides that, the potentialities of PG2 have been put in use in juice clarification of pear, banana and citrus juice. Copyright © 2016 Elsevier B.V. All rights reserved.

Derivatized-agarose supports are suitable for enzyme immobilization by different methods, taking advantage of different physical, chemical and biological conditions of the protein and the support. In this study, agarose particles were modified with MANAE, PEI and glyoxyl groups and evaluated to stabilize polygalacturonase from Streptomyces halstedii ATCC 10897. A new immobilized biocatalyst was developed using glyoxyl-agarose as support; it exhibited high performance in degrading polygalacturonic acid and releasing oligogalacturonides. Maximal enzyme activity was detected at 5h of reaction using 0.05g/mL of immobilized biocatalyst, which released 3mg/mL of reducing sugars and allowed the highest product yield conversion and increased stability. These results are very favorable for pectin degradation with reusability up to 18 successive reactions (90h) and application in juice clarification. Plum (4.7°Bx) and grape (10.6°Bx) juices were successfully clarified, increasing reducing sugars content and markedly decreasing turbidity and viscosity. Copyright © 2016 Elsevier Ltd.

Effect of magnetic starch on the clarification of hematite tailings wastewater

NASA Astrophysics Data System (ADS)

Yue, Tao; Wu, Xiqing

2018-02-01

The magnetic starch solution, synthesized by mixing the caustic starch, the Fe2+ solution (in some cases containing the Zn2+, Cu2+, Mn2+ or Mg2+ ions) and H2O2 solution, was used as the flocculant to investigate its clarification effect on hematite tailings wastewater. Based on the clarification tests and adsorption analysis it was demonstrated that the magnetic starch produced better clarification effect than the caustic starch, and the adsorption of magnetic starch onto hematite tailings particles was also stronger than the caustic starch. AFM found that the magnetic interaction between magnetic seeds and hematite is characteristic of long range force and greatly strengthens the adsorption of magnetic seeds onto fine hematite for agglomeration. FTIR indicates the starch adsorbed onto the surfaces of hematite and magnetic seeds, thus acting as the bridging between hematite particles and magnetic seeds, resulting in an intensified coverage of the starch onto hematite and positive action in the clarification.

Study of virgin olive oil clarification by settling under dynamic conditions.

Gila, Abraham; Bejaoui, Mohamed Aymen; Beltrán, Gabriel; Aguilera, María Paz; Jiménez, Antonio

2018-04-16

Vertical centrifugation is the main method for virgin olive oil (VOO) clarification. However, in recent years, settling tanks are also being used to clarify the oils from decanters. They can operate under static or dynamic conditions. In this work, vertical centrifugation and settling under dynamic conditions for VOO clarification and their effects on VOO characteristics were compared. VOO quality parameters were not affected by the clarification systems studied. The vertical centrifugal separator (VCS) showed higher clarification efficiency, giving clarified oils with higher phenol content and better sensory characteristics. VOOs clarified by dynamic settling showed notable losses of phenols and worse sensory characteristics, since the tank purge system was not efficient, with most of the impurities remaining in the tanks. The VCS with minimal water addition is a quick operation with low water consumption and is a better option to produce VOOs of improved quality, especially in terms of longer shelf life and preservation of positive sensory notes. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry.

This is the fundamental question for understanding what our minds are and is related to the verification of Hebb's cell assembly theory. The second is "how is information distributed in the brain?" This is also a reconsideration of the functional localization of the brain. The third is "what is the function of the ongoing activity of the brain?" This is the problem of how the brain is active during no-task periods and what meaning such spontaneous activity has. The fourth is "how does the bodily behavior affect the brain function?" This is the problem of brain-body interaction, and obtaining a new "body" by a BMI leads to a possibility of changes in the owner's brain. The last is "to what extent can the brain induce plasticity?" Most BMIs require changes in the brain's neuronal activity to realize higher performance, and the neuronal operant conditioning inherent in the BMIs further enhances changes in the activity.

Differential change in integrative psychotherapy: a re-analysis of a change-factor based RCT in a naturalistic setting.

General Psychotherapy (GPT; Grawe, 1997) is a research-informed psychotherapy that combines cognitive-behavioral and process-experiential techniques and that assumes motivational clarification and problem mastery as central mechanisms of change. To isolate the effect of motivational clarification, GPT was compared to a treatment that proscribed motivational clarification (General Psychotherapy Minus Clarification, GPT-C) in a randomized-controlled trial with 67 diagnostically heterogeneous outpatients. Previous analyses demonstrated equal outcomes and some superiority for highly avoidant patients in GPT. Re-analyses using causal-analytic methods confirmed equal changes, but also showed superior effects for GPT in highly symptomatic patients. Results are discussed regarding theory, methodological limitations, and implications for research and practice.

Power, Professional Naiveté and Environmental Icebergs: Navigating the Bioethics Ecosystem.

Doing bioethics in the public arena of healthcare, government, business or academia takes courage and stamina. The effort involved must be greater than just supporting clients through disciplined arguments and an ongoing process of clarification. Beyond the argument, for ethicists to be of value, they must understand the importance of navigating power structures within the bioethics ecosystem and to recognize their own professional naiveté.

Patients with multiple chronic conditions often face competing demands for care, and they often do not agree with physicians on priorities for care. Patients ’ values shape their healthcare priorities, but existing methods for eliciting values do not necessarily meet patients ’ care planning needs. We developed a patient-centered values framework based on a field study with patients and caregivers. In this paper we report on a survey to evaluate how the framework generalizes beyond field study participants, and how well the framework supports values elicitation. We found that respondents frame values in a way that is consistent with the framework, and that domains of the framework can be used to elicit a breadth of potential values individuals with MCC express. These findings demonstrate how a patient-centered perspective on values can expand on the domains considered in values clarification methods andfacilitate patient-provider communication in establishing shared care priorities.

Challenging the coherence of social justice as a shared nursing value.

PubMed

Lipscomb, Martin

2011-01-01

Normative and prescriptive claims regarding social justice are often inadequately developed in the nursing literature and, in consequence, they must be rejected in their current form. Thus, claims regarding social justice are frequently presented as mere assertion (without clarification or supporting argument) or, alternatively, when assertions are supported that support may be weak (e.g. social justice is repeated juxtaposed against contentious assumptions regarding market disutility). This paper challenges the coherence of social justice as a shared nursing value and it is suggested that claims regarding the concept should be tempered. © 2010 Blackwell Publishing Ltd.

Conrad, C A; Williams, J R

2000-12-01

The psychometric properties of the Value Consciousness Scale developed by Lichtenstein, Netemeyer, and Burton in 1990 were examined in a retail grocery study (N = 497). Original assessment of scale properties was undertaken using two convenience samples in a nonretail setting and additional scale performance has been documented by the scale authors. This study furthers previous research by (1) examining performance on the items in the retail grocery setting and (2) utilizing an appropriately rigorous sampling procedure. A confirmatory factor analysis indicated that the Value Consciousness Scale does not exhibit unidimensional properties, and one must be cautious if this scale is used in applications of market segmentation until further clarification can be provided.

The environmental impacts of palm oil mill effluent (POME) have been a concern due to the water pollution and greenhouse gases emissions. Thus, this study was conducted to recover the value-added products from POME source before being discharged. The samples, before (X) and after (Y) the pre-recovery system in the clarification tank were sampled and analysed and proximate analysis indicated that both samples are energy rich source of food due to high contents of fats and carbohydrates. GCMS analysis showed that the oil extracts contain predominantly palmitic, oleic, linoleic and stearic acids. Regiospecific analysis of oil extracts by quantitative 13 C-NMR spectroscopy demonstrated that both oil extracts contain similar degree of saturation of fatty acids at sn-2 and sn-1,3 positions. The samples are rich in various phytonutrients, pro-vitamin A, vitamin E, squalene and phytosterols, thus contributing to exceptionally high total flavonoid contents and moderate antioxidant activities. Overall, samples X and Y are good alternative food sources, besides reducing the environmental impact of POME.

Population change and socio-cultural values.

PubMed

1982-06-01

The developing countries of the world in general, and those of Asia and the Pacific in particular, recognize that unplanned population growth is a stumbling block to socioeconomic development. Discussion here focuses on population growth and social, economic, and institutional forces, which are referred to as sociocultural values. Generally, sociocultural values change sluggishly over time. The rate at which a country's sociocultural values change depends on several factors such as the stage of economic development and modernization and whether a country has an open or closed door policy. "The Value of Children Study: A Crossnational Study" by Fred Arnold et al. shows that there are positive and negative values attributed to children in the Asian countries. These are: positive general values--emotional benefits, economic benefits and security, self enrichment and development, identification with children, and family cohesiveness and continuity; negative general values--emotional costs, economic costs, restrictions on opportunity costs, physical demands, and family costs; large family values--sibling relationships, sex preferences, child survival; and small family values--maternal health and societal costs. Possibly the most formidable obstacle to the success of antinatalist population policies is that of religious values. It appears that the Muslim world is divided on the issue of fertility control. Conflicting views regarding fertility control is perhaps aggravated by the fact that there is no central international religious official hierarchy that issues out edicts. Despite the presence of a centralized religious hierarchy and a network of churches from the Vatican to the village levels among the Catholics, and a clearer elucidation of the Humanae Vitae, a liberal attitude to population regulation and family planning has emerged, largely because of the declining quality of life of the people resulting from unplanned births. Economic benefits of children include benefits from children's help in the house, business, or farm, from care of siblings, and from sharing of income; and old age security for the parents, including economic support, physical care, and psychological security. People in some countries of the region have a number of prenatalist values and beliefs, including a preference for sons. Changing attitudes and social realities have resulted in value changes, value crises, value conflicts, and confusion. Value clarification has much potential in terms of a couple's decision making. Values clarification involves at least 7 steps: choosing freely; choosing from alternatives; choosing after thoughtful consideration of consequences; prizing and cherishing; publicly affirming; acting; and acting with some pattern.

The role of assessment packages for diagnostic consultations: A conversation analytic perspective.

PubMed

Rossen, Camilla B; Buus, Niels; Stenager, Egon; Stenager, Elsebeth

2015-05-01

This article reports a conversation analysis of assessment package consultations. Healthcare delivery packages belong to a highly structured mode of healthcare delivery, in which specific courses of healthcare interventions related to assessment and treatment are predefined, both as to timing and content. Assessment packages are widely used in an increasing number of medical specialities; however, there is a lack of knowledge about how packaged assessment influences the interaction between doctor and patient. In this study, we investigate the final consultation in assessment packages, which is when the final clarification of the patient's symptoms takes place. The primary data of the study were eight audio recordings of consultations, and the secondary data were ethnographic field descriptions. In most consultations, packaged assessment was a resource as it provided fast and efficient clarification. In most cases, clarification was treated as good news since it either confirmed the absence of a serious disease or resulted in a diagnosis leading to relevant treatment offers. However, in some cases, clarification was not perceived as good news. This was the case in consultations with patients whose goal was to leave the consultation with clarification in the form of a definite diagnosis, but who were not offered such clarification. These patients negotiated the outcome of the consultation by applying implicit and explicit pressure, which induced the doctors to disregard the boundaries of the package and offer the patient more tests. The study highlights some of the problems related to introducing narrow, specialized package assessment. © The Author(s) 2014.

Chitosan as a novel clarifying agent on clear apple juice production: Optimization of process conditions and changes on quality characteristics.

PubMed

Taştan, Özge; Baysal, Taner

2017-12-15

In this study, the use of chitosan as a clarification agent in the production of clear apple juice (AJ) was investigated, the optimum conditions were determined using RSM, and the effects on the quality of AJ were analyzed during storage at 4°C and 20°C for 4months. Optimum conditions for clarifying the AJ were chitosan concentration of 191.6mg/100ml juice, the process temperature of 20°C and process time of 30min. Changes in quality characteristics such as turbidity, pH, acidity, color, total monomeric anthocyanin, total phenolic, and protein contents were evaluated and compared to traditional clarification. Alicyclobacillus acidoterrestris causes significant safety issues in fruit juice industry; therefore also the antimicrobial effect of chitosan on A. acidoterrestris during the clarification process was examined. The results showed that clear AJ production can be achieved by the clarification step with direct chitosan addition, without the need for enzymatic treatment. However, the microbial reduction of A. acidoterrestris during the clarification process was not found to be significant. Copyright © 2017 Elsevier Ltd. All rights reserved.

Delayed clarification: information, clarification and ethical decisions in critical care in Norway.

PubMed

Bunch, E H

2000-12-01

Following the analysis of about 150 hours of field observation on a critical care unit in Norway a theory was generated to explain the actual ethical decision-making process. This was grounded in the empirical reality of physicians, nurses and family. The core theme in this study was a delayed clarification in assessing the prognosis of accident victims with neurosurgical traumas. The physicians, nurses and family had to wait for the clinical picture to clarify, during which time there was an exchange and emergence of information. Exchanging information, a subprocess to delayed clarification, involved a continuous flow of collecting and dispersing information about the clinical status of the patient. The nurses engaged in two useful strategies: grading information to family when the patient prognosis was poor, and providing grieving strategies for themselves, colleagues and family members. The core variable, delayed clarification has three dimensions: clinical, psychological and ethical. The nurses participated in the decision-making process to discontinue treatment as passive participants, they did not engage in collegial deliberations with the physicians. Ethical dilemmas were end of life questions, resource allocations, and questions of justice and organ transplants.

Computational chemical analysis of unconjugated bilirubin anions and insights into pKa values clarification

NASA Astrophysics Data System (ADS)

Vega-Hissi, Esteban G.; Estrada, Mario R.; Lavecchia, Martín J.; Pis Diez, Reinaldo

2013-01-01

The pKa, the negative logarithm of the acid dissociation equilibrium constant, of the carboxylic acid groups of unconjugated bilirubin in water is a discussed issue because there are quite different experimental values reported. Using quantum mechanical calculations we have studied the conformational behavior of unconjugated bilirubin species (in gas phase and in solution modeled implicitly and explicitly) to provide evidence that may clarify pKa values because of its pathophysiological relevance. Our results show that rotation of carboxylate group, which is not restricted, settles it in a suitable place to establish stronger interactions that stabilizes the monoanion and the dianion to be properly solvated, demonstrating that the rationalization used to justify the high pKa values of unconjugated bilirubin is inappropriate. Furthermore, low unconjugated bilirubin (UCB) pKa values were estimated from a linear regression analysis.

Immobilization of pectinase onto chitosan magnetic nanoparticles by macromolecular cross-linker.

Sojitra, Uttam V; Nadar, Shamraja S; Rathod, Virendra K

2017-02-10

Pectinase was immobilized onto chitosan magnetic nanoparticles (CMNPs) by dextran polyaldehyde as a macromolecular cross-linking agent. The parameters like cross-linking concentration, time and CMNPs to enzyme ratio were optimized. Further, prepared magnetic pectinase nanobiocatalyst was characterized by FT-IR and XRD. The thermal kinetic studies for immobilized pectinase showed two folds improved thermal stability in the range of 55-75°C as compared to free form. The V max and K m values of immobilized pectinase were found to be nearly equal to native form which indicated that conformational flexibility of pectinase was retained even after immobilization. The residual activity of immobilized pectinase was 85% after seven successive cycles of reuse, while it retained upto 89% residual activity on storage of fifteen days which exhibited excellent stability and durability. The conformational changes in pectinase after immobilization were evaluated by FT-IR spectroscopy data analysis tools. Finally, magnetic pectinase nanobiocatalyst was employed for apple juice clarification which showed turbidity reduction upto 74% after 150min treatment. Copyright © 2016 Elsevier Ltd.

Rice, Anna; Austin, John; Gravina, Nicole

2009-01-01

This project assessed an intervention to improve employee customer service behaviors (correct greetings and closing behaviors). A combination of task clarification and manager-delivered social praise resulted in increased correct greeting from 11.5% to 66% and correct closing from 8% to 70%. The effect was maintained at a 48-week follow-up for employees who were present during the initial study period, but not for more recently hired employees. The results suggest that task clarification combined with manager-delivered social praise is an effective way to improve employee customer service behaviors.

Theory-informed design of values clarification methods: a cognitive psychological perspective on patient health-related decision making.

PubMed

Pieterse, Arwen H; de Vries, Marieke; Kunneman, Marleen; Stiggelbout, Anne M; Feldman-Stewart, Deb

2013-01-01

Healthcare decisions, particularly those involving weighing benefits and harms that may significantly affect quality and/or length of life, should reflect patients' preferences. To support patients in making choices, patient decision aids and values clarification methods (VCM) in particular have been developed. VCM intend to help patients to determine the aspects of the choices that are important to their selection of a preferred option. Several types of VCM exist. However, they are often designed without clear reference to theory, which makes it difficult for their development to be systematic and internally coherent. Our goal was to provide theory-informed recommendations for the design of VCM. Process theories of decision making specify components of decision processes, thus, identify particular processes that VCM could aim to facilitate. We conducted a review of the MEDLINE and PsycINFO databases and of references to theories included in retrieved papers, to identify process theories of decision making. We selected a theory if (a) it fulfilled criteria for a process theory; (b) provided a coherent description of the whole process of decision making; and (c) empirical evidence supports at least some of its postulates. Four theories met our criteria: Image Theory, Differentiation and Consolidation theory, Parallel Constraint Satisfaction theory, and Fuzzy-trace Theory. Based on these, we propose that VCM should: help optimize mental representations; encourage considering all potentially appropriate options; delay selection of an initially favoured option; facilitate the retrieval of relevant values from memory; facilitate the comparison of options and their attributes; and offer time to decide. In conclusion, our theory-based design recommendations are explicit and transparent, providing an opportunity to test each in a systematic manner. Copyright © 2012 Elsevier Ltd. All rights reserved.

Artificial neural network (ANN)-based prediction of depth filter loading capacity for filter sizing.

Agarwal, Harshit; Rathore, Anurag S; Hadpe, Sandeep Ramesh; Alva, Solomon J

2016-11-01

This article presents an application of artificial neural network (ANN) modelling towards prediction of depth filter loading capacity for clarification of a monoclonal antibody (mAb) product during commercial manufacturing. The effect of operating parameters on filter loading capacity was evaluated based on the analysis of change in the differential pressure (DP) as a function of time. The proposed ANN model uses inlet stream properties (feed turbidity, feed cell count, feed cell viability), flux, and time to predict the corresponding DP. The ANN contained a single output layer with ten neurons in hidden layer and employed a sigmoidal activation function. This network was trained with 174 training points, 37 validation points, and 37 test points. Further, a pressure cut-off of 1.1 bar was used for sizing the filter area required under each operating condition. The modelling results showed that there was excellent agreement between the predicted and experimental data with a regression coefficient (R 2 ) of 0.98. The developed ANN model was used for performing variable depth filter sizing for different clarification lots. Monte-Carlo simulation was performed to estimate the cost savings by using different filter areas for different clarification lots rather than using the same filter area. A 10% saving in cost of goods was obtained for this operation. © 2016 American Institute of Chemical Engineers Biotechnol. Prog., 32:1436-1443, 2016. © 2016 American Institute of Chemical Engineers.

Scrophularia genus belonging to the family of Scrophulariaceae, is a medicinal plant widely distributed in Iran. In the present study, the anti-malarial activity of different extracts of three Iranian endemic species of Scrophularia including S. frigida, S. subaphylla and S. atropatana, was screened by an in-vitro preliminary assay. The plant materials were extracted successively with n-hexane, dichloromethane (DCM), and methanol (MeOH) at room temperature by soxhlet extractor. In order to assess anti-malarial activity of obtained extracts, cell free β-hematin formation assay was applied. Amongst the extracts, DCM extract of S. frigida exhibited remarkable anti-malarial activity with IC50 value of 0.67 ± 0.11 mg/mL. In contrast, MeOH and n-hexane extracts of all plants illustrated insignificant or moderate activity in this assay. Furthermore, preliminary phytochemical analysis along with TLC and GC-MS analysis of potent extract (DCM extract of S. frigida) were performed for more clarification. These methods revealed that the notable anti-malarial activity might be due to the presence of active constituents like methoxylated flavonoids, methylated coumarins, and diterpenoids. From the nine extracts of different species of Scrophularia, DCM extract of S. frigida showed potent inhibitory activity on β-hematin formation assay. Hence, it seems that it is noteworthy to concentrate on purifying the active chemical constituents of DCM extract and determining the pure anti-malarial components. PMID:29881424

In recent years several OECD test guidelines have been updated and some will be updated shortly with the requirement to measure thyroid hormone levels in the blood of mammalian laboratory species. There is, however, an imperative need for clarification and guidance regarding the collection, assessment, and interpretation of thyroid hormone data for regulatory toxicology and risk assessment. Clarification and guidance is needed for 1) timing and methods of blood collection, 2) standardization and validation of the analytical methods, 3) triggers for additional measurements, 4) the need for T4 measurements in postnatal day (PND) 4 pups, and 5) the interpretation of changes in thyroid hormone levels regarding adversity. Discussions on these topics have already been initiated, and involve expert scientists from a number of international multisector organizations. This paper provides an overview of existing issues, current activities and recommendations for moving forward. Copyright © 2018 Elsevier Inc. All rights reserved.

Effect of acidification on carrot (Daucus carota) juice cloud stability.

PubMed

Schultz, Alison K; Barrett, Diane M; Dungan, Stephanie R

2014-11-26

Effects of acidity on cloud stability in pasteurized carrot juice were examined over the pH range of 3.5-6.2. Cloud sedimentation, particle diameter, and ζ potential were measured at each pH condition to quantify juice cloud stability and clarification during 3 days of storage. Acidification below pH 4.9 resulted in a less negative ζ potential, an increased particle size, and an unstable cloud, leading to juice clarification. As the acidity increased, clarification occurred more rapidly and to a greater extent. Only a weak effect of ionic strength was observed when sodium salts were added to the juice, but the addition of calcium salts significantly reduced the cloud stability.

[Informed consent consultation as a part of patient safety in pediatric traumatology].

PubMed

Kraus, R; Heberer, J

2013-10-01

In pediatric traumatology as in any other surgical specialty, every treatment measure has to be protected by an adequate clarification. A legally effective clarification has to cover various aspects, such as diagnosis, treatment, risk and safety clarification and leads to an informed consent consultation. The contents of this informed consent discussion must be documented. The nature and extent of clarification, among other things depend on the urgency of the procedure and in an emergency it can be dispensed with in pediatric traumatology. In the case of minors the conversation must be conducted basically in the presence of both parents as they alone are legally entitled to give approval. General treatment proxies are not allowed. If it is not possible to talk to both parents the physician is allowed to trust that the parent present represents the will of the absent parent. Intervention cannot be carried out against the will of adolescents capable of self-determination even with the consent of the parents. The application of these rules is illustrated by means of practical examples.

Concept Analysis: Music Therapy.

PubMed

Murrock, Carolyn J; Bekhet, Abir K

2016-01-01

Down through the ages, music has been universally valued for its therapeutic properties based on the psychological and physiological responses in humans. However, the underlying mechanisms of the psychological and physiological responses to music have been poorly identified and defined. Without clarification, a concept can be misused, thereby diminishing its importance for application to nursing research and practice. The purpose of this article was for the clarification of the concept of music therapy based on Walker and Avant's concept analysis strategy. A review of recent nursing and health-related literature covering the years 2007-2014 was performed on the concepts of music, music therapy, preferred music, and individualized music. As a result of the search, the attributes, antecedents, and consequences of music therapy were identified, defined, and used to develop a conceptual model of music therapy. The conceptual model of music therapy provides direction for developing music interventions for nursing research and practice to be tested in various settings to improve various patient outcomes. Based on Walker and Avant's concept analysis strategy, model and contrary cases are included. Implications for future nursing research and practice to use the psychological and physiological responses to music therapy are discussed.

Towards a Kieselguhr- and PVPP-Free Clarification and Stabilization Process of Rough Beer at Room-Temperature Conditions.

PubMed

Cimini, Alessio; Moresi, Mauro

2018-01-01

In this work, the main constraint (that is, beer chilling and chill haze removing) of the current beer conditioning techniques using Kieselguhr filtration and Polyvinylpolypyrrolidone (PVPP) treatment was overcome by developing a novel higher-throughput conditioning process, operating at room temperatures with no use of filter aids. The effect of filtration temperature (T F ) in the range of 0 to 40 °C on the hydraulic permeability of ceramic hollow-fiber (HF) membranes with nominal pore size of 0.2 to 1.4 μm, as well as on their limiting permeation flux (J * ) when feeding precentrifuged rough beer, was preliminarily assessed. When using the 1.4-μm HF membrane operating at T F ≥ 20 °C, it was possible to enhance the average permeation flux at values (676 to 1844 L/m 2 /h), noticeably higher than those (250 to 500 L/m 2 /h) characteristics of conventional powder filtration. Despite its acceptable permanent haze, the resulting beer permeate still exhibited colloidal instability. By resorting to the commercial enzyme preparation Brewers Clarex® before beer clarification, it was possible to significantly improve its colloidal stability as measured using a number of European Brewing Convention forcing tests, especially with respect to that of precentrifuged rough beer by itself. By combining the above enzymatic treatment with membrane clarification at 30 °C across the ceramic 1.4-μm HF membrane module, it was possible to limit the haze development due to chilling, sensitive proteins, and alcohol addition to as low as 0.78, 4.1, and 4.0 EBC-U, respectively, the enzymatic treatment being by far more effective than that using PVPP. A novel Kieselguhr- and PVPP-free rough beer conditioning process at room temperatures was set up. By submitting precentrifuged rough beer to commercial preparation Brewers Clarex ® and then to membrane clarification at 30 °C across a ceramic 1.4-μm hollow-fiber membrane module, it was possible to obtain a clear and stable beer with a throughput (1306 ± 72 L/m 2 /h) by far higher than that (250 to 500 L/m 2 /h) characterizing the current powder filters. The haze development due to chilling, sensitive proteins, and alcohol adding was by far lower than that observed when microfiltering PVPP-pretreated rough beer. © 2017 Institute of Food Technologists®.

Thyrotropin receptor mutations and thyroid hyperfunctioning adenomas ten years after their first discovery: unresolved questions.

PubMed

Arturi, F; Scarpelli, D; Coco, A; Sacco, R; Bruno, R; Filetti, S; Russo, D

2003-04-01

Ten years after the first description of activating mutations in the thyroid stimulating hormone receptor (TSHR) gene in sporadic autonomous hyperfunctioning thyroid adenomas, there is general agreement in assigning a major pathogenic role of this genetic abnormality, acting via the constitutive activation of the cAMP pathway, in both the growth and functional characteristic of these tumours. From the beginning, however, the pathophysiological and clinical relevance of somatic TSHR mutations has been debated and some arguments still exist against a fully causative role of these mutations and the practical value of detecting these mutations for the diagnosis, treatment and prognosis of thyroid hot nodules. Some major issues will be examined herein, including (a) the frequency of TSHR alterations in various reports showing that the genetic abnormality underlying the pathogenesis of a substantial subset of thyroid tumours has yet to be identified; (b) the limitations of the present experimental models, which suggest greater caution in the interpretation of in vitro results; (c) the still unresolved question of absence of genotype-phenotype correlation. Clarification of these issues may hopefully provide new and useful tools for improving the clinical management of this disease.

Implementation of interprofessional learning activities in a professional practicum: The emerging role of technology.

PubMed

Brault, Isabelle; Therriault, Pierre-Yves; St-Denis, Louise; Lebel, Paule

2015-01-01

To prepare future healthcare professionals to collaborate effectively, many universities have developed interprofessional education programs (IPE). Till date, these programs have been mostly courses or clinical simulation experiences. Few attempts have been made to pursue IPE in healthcare clinical settings. This article presents the results of a pilot project in which interprofessional learning activities (ILAs) were implemented during students' professional practicum and discusses the actual and potential use of informatics in the ILA implementation. We conducted a pilot study in four healthcare settings. Our analysis is based on focus group interviews with trainees, clinical supervisors, ILA coordinators, and education managers. Overall, ILAs led to better clarification of roles and understanding of each professional's specific expertise. Informatics was helpful for developing a common language about IPE between trainees and healthcare professionals; opportunities for future application of informatics were noted. Our results support the relevance of ILAs and the value of promoting professional exchanges between students of different professions, both in academia and in the clinical setting. Informatics appears to offer opportunities for networking among students from different professions and for team members' professional development. The use of technology facilitated communication among the participants.

Effect of adsorbent addition on floc formation and clarification.

PubMed

Younker, Jessica M; Walsh, Margaret E

2016-07-01

Adding adsorbent into the coagulation process is an emerging treatment solution for targeting hard-to-remove dissolved organic compounds from both drinking water and industrial wastewater. The impact of adding powdered activated carbon (PAC) or organoclay (OC) adsorbents with ferric chloride (FeCl3) coagulant was investigated in terms of potential changes to the coagulated flocs formed with respect to size, structure, and breakage and regrowth properties. The ability of dissolved air flotation (DAF) and sedimentation (SED) clarification processes to remove hybrid adsorbent-coagulant flocs was also evaluated through clarified water quality analysis of samples collected in bench-scale jar test experiments. The jar tests were conducted using both a synthetic fresh water and oily wastewater test water spiked with dissolved aromatic compounds phenol and naphthalene. Results of the study demonstrated that addition of adsorbent reduced the median coagulated floc size by up to 50% but did not affect floc strength or regrowth potential after application of high shear. Experimental results in fresh water demonstrated that sedimentation was more effective than DAF for clarification of both FeCl3-PAC and FeCl3-OC floc aggregates. However, experimental tests performed on the synthetic oily wastewater showed that coagulant-adsorbent floc aggregates were effectively removed with both DAF and sedimentation treatment, with lower residual turbidity achieved in clarified water samples than with coagulation treatment alone. Addition of OC or PAC into the coagulation process resulted in removals of over half, or nearly all of the dissolved aromatics, respectively. Copyright © 2016 Elsevier Ltd. All rights reserved.

How do patients between the age of 65 and 75 use a web-based decision aid for treatment choice in localized prostate cancer?

PubMed

Schrijvers, Jessie; Vanderhaegen, Joke; Van Poppel, Hendrik; Haustermans, Karin; Van Audenhove, Chantal

2013-08-01

This study was designed to evaluate the use of a web-based decision aid by a 65plus patient group in their decision-making process for treatment of localized prostate cancer. Of particular interest was the use of technology features such as patients' statements, comparative tables, and a values clarification tool. One hundred men from the University Hospital of Leuven campus, Gasthuisberg, were invited to use the web-based decision aid in their decision-making process. Twenty-six men were excluded based on non- or limited use of the decision aid. Of the remaining 74 men, user specifications, decision aid surfing characteristics by means of web-log data, and especially the use of technology features were analyzed. Men spent on average 30 minutes on the web-based decision aid. Most time was spent on the pages with information on treatment options. These pages were also most frequently accessed. The use of the feature 'comparative tables' was the highest, followed by the 'values clarification tool'. According to age (<70 or >70 years) differences were observed for the time spent on the decision aid, the pages accessed, and the use of the technology features. Despite concerns about the usability of a web-based decision aid for elderly patients, these results indicated that the majority of 65plus persons with good internet skills use a web-based decision aid as well as its incorporated technology features. © 2013 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

Task clarification, performance feedback, and social praise: Procedures for improving the customer service of bank tellers

PubMed Central

Crowell, Charles R.; Anderson, D. Chris; Abel, Dawn M.; Sergio, Joseph P.

1988-01-01

Customer service for bank tellers was defined in terms of 11 verbal behavior categories. An audio-recording system was used to track the occurrence of behaviors in these categories for six retail banking tellers. Three behavior management interventions (task clarification, performance feedback, and social praise), applied in sequence, were designed to improve overall teller performance with regard to the behavioral categories targeted. Clarification was accomplished by providing clear delineation of the various target categories, with specific examples of the behaviors in each. Feedback entailed presentation of ongoing verbal and visual information regarding teller performance. Praise consisted of verbal recognition of teller performance by branch managers. Results showed that clarification effects emerged quickly, producing an overall increase in desired behaviors of 12% over baseline. Feedback and praise effects occurred more gradually, resulting in overall increases of 6% and 7%, respectively. A suspension of all procedures led to a decline in overall performance, whereas reinstatement of feedback and praise was again accompanied by performance improvement. These findings extend the generality of behavior management applications and help to distinguish between possible antecedent and consequent effects of performance feedback. PMID:16795713

Role Clarification Processes for Better Integration of Nurse Practitioners into Primary Healthcare Teams: A Multiple-Case Study

2014-01-01

Role clarity is a crucial issue for effective interprofessional collaboration. Poorly defined roles can become a source of conflict in clinical teams and reduce the effectiveness of care and services delivered to the population. Our objective in this paper is to outline processes for clarifying professional roles when a new role is introduced into clinical teams, that of the primary healthcare nurse practitioner (PHCNP). To support our empirical analysis we used the Canadian National Interprofessional Competency Framework, which defines the essential components for role clarification among professionals. A qualitative multiple-case study was conducted on six cases in which the PHCNP role was introduced into primary care teams. Data collection included 34 semistructured interviews with key informants involved in the implementation of the PHCNP role. Our results revealed that the best performing primary care teams were those that used a variety of organizational and individual strategies to carry out role clarification processes. From this study, we conclude that role clarification is both an organizational process to be developed and a competency that each member of the primary care team must mobilize to ensure effective interprofessional collaboration.

To explore the unsettling effects of increased mobility of nurses, surgeons and other healthcare professionals on communication and learning in the operating theatre. Increasingly, healthcare professionals step in and out of newly formed transient teams and work with colleagues they have not met before, unsettling previously relatively stable team work based on shared, local knowledge accumulated over significant periods of close collaboration. An ethnographic case study was conducted of the operating theatre department of a major teaching hospital in London. Video recordings were made of 20 operations, involving different teams. The recordings were systematically reviewed and coded. Instances where difficulties arose in the communication between scrub nurse and surgeons were identified and subjected to detailed, interactional analysis. Instrument requests frequently prompted clarification from the scrub nurse (e.g. 'Sorry, what did you want?'). Such requests were either followed by a relatively elaborate clarification, designed to maximize learning opportunities, or a by a relatively minimal clarification, designed to achieve the immediate task at hand. Significant variation exists in the degree of support given to scrub nurses requesting clarification. Some surgeons experience such requests as disruptions, while others treat them as opportunities to build shared knowledge. © 2015 John Wiley & Sons Ltd.

Polygalacturonase and α-amylase play vital role in fruit juice industry. In the present study, polygalacturonase was produced by Aspergillus awamori Nakazawa MTCC 6652 utilizing apple pomace and mosambi orange (Citrus sinensis var mosambi) peels as solid substrate whereas, α-amylase was produced from A. oryzae (IFO-30103) using wheat bran by solid state fermentation (SSF) process. These carbohydrases were decolourized and purified 8.6-fold, 34.8-fold and 3.5-fold, respectively by activated charcoal powder in a single step with 65.1%, 69.8% and 60% recoveries, respectively. Apple juice was clarified by these decolourized and partially purified enzymes. In presence of 1% polygalacturonase from mosambi peels (9.87 U/mL) and 0.4% α-amylase (899 U/mL), maximum clarity (%T(660 nm) = 97.0%) of juice was attained after 2 h of incubation at 50 °C in presence of 10 mM CaCl2. Total phenolic content of juice was reduced by 19.8% after clarification, yet with slightly higher %DPPH radical scavenging property.

Streptococcus pneumoniae is the main cause of pneumonia, meningitis, and other conditions that kill thousands of children every year worldwide. The replacement of pneumococcal serotypes among the vaccinated population has evidenced the need for new vaccines with broader coverage and driven the research for protein-based vaccines. Pneumococcal surface protein A (PspA) protects S. pneumoniae from the bactericidal effect of human apolactoferrin and prevents complement deposition. Several studies indicate that PspA is a very promising target for novel vaccine formulations. Here we describe a production and purification process for an untagged recombinant fragment of PspA from clade 4 (PspA4Pro), which has been shown to be cross-reactive with several PspA variants. PspA4Pro was obtained using lactose as inducer in Phytone auto-induction batch or glycerol limited fed-batch in 5-L bioreactor. The purification process includes two novel steps: (i) clarification using a cationic detergent to precipitate contaminant proteins, nucleic acids, and other negatively charged molecules as the lipopolysaccharide, which is the major endotoxin; and (ii) cryoprecipitation that eliminates aggregates and contaminants, which precipitate at -20 °C and pH 4.0, leaving PspA4Pro in the supernatant. The final process consisted of cell rupture in a continuous high-pressure homogenizer, clarification, anion exchange chromatography, cryoprecipitation, and cation exchange chromatography. This process avoided costly tag removal steps and recovered 35.3 ± 2.5% of PspA4Pro with 97.8 ± 0.36% purity and reduced endotoxin concentration by >99.9%. Circular dichroism and lactoferrin binding assay showed that PspA4Pro secondary structure and biological activity were preserved after purification and remained stable in a wide range of temperatures and pH values.

The drug industry has a poor public image. Although its role is to treat disease, it has a poorer reputation than cigarette makers or the automotive industry. This situation must be analysed from three overlapping points of view: 1) the complexity of a market, in which most of the costs are hidden; 2) the difficulty of a connected society to organize debates on political questions related to basic values, and finally 3) the pervading distinction between morality and profits. This clarification might help the industry to become a fully fledged actor in the field of healthcare in order to participate in the improvement of the healthcare offer for the population.

While there is a plethora of evidence for the efficacy of cognitive-behavioural therapy (CBT) in obsessive-compulsive disorder (OCD), studies on change factors of the therapeutic process that account for this success are scarce. In the present study, 155 participants with primary OCD were investigated during CBT inpatient treatment. The Yale-Brown Obsessive-Compulsive Scale-SR served as a measure of symptom severity. In addition, the following process change factors were measured: therapeutic relationship, experience of self-esteem during therapy, experience of mastery, problem actualization and clarification. All variables were assessed on a weekly basis for seven weeks. Linear mixed growth curve analyses were conducted to model the decrease of symptoms over time and to analyse whether the change factors predicted symptom reduction. The analyses revealed a linear decrease of symptoms with high inter-individual variation. Results further showed that increase in self-esteem and mastery experiences as well as the initial score on mastery experience and clarification predicted decrease on the Y-BOCS. We conclude that CBT therapists should focus on clarification in the very first sessions, and try to boost self-esteem and self-efficacy, which is related to mastery, throughout the treatment of OCD.

Tricas-Sauras, Sandra; Darras, Elisabeth; Macq, Jean

2017-01-01

This study aimed to assess interprofessional collaboration between general physicians and emergency departments in the French speaking regions of Belgium. Eight group interviews were conducted both in rural and urban areas, including in Brussels. Findings showed that the relational components of collaboration, which are highly valued by individuals involved, comprise mutual acquaintanceship and trust, shared power and objectives. The organizational components of collaboration included out-of-hours services, role clarification, leadership and overall environment. Communication and patient’s role were also found to be key elements in enhancing or hindering collaboration across these two levels of care. Relationships between general physicians and emergency departments’ teams were tightly linked to organizational factors and the general macro-environment. Health system regulation did not appear to play a significant role in promoting collaboration between actors. A better role clarification is needed in order to foster multidisciplinary team coordination for a more efficient patient management. Finally, economic power and private practice impeded interprofessional collaboration between the care teams. In conclusion, many challenges need to be addressed for achievement of a better collaboration and more efficient integration. Not only should integration policies aim at reinforcing the role of general physicians as gatekeepers, also they should target patients’ awareness and empowerment. PMID:29588632

The polyphenol contents and colors of cider apple juices were compared before (NCM, not clarified must) and after five clarification treatments: enzymatic depectinization by pectinases followed by (i) sedimentation (depectinized and decanted juice), (ii) tangential microfiltration (microfiltered juice) or (iii) fining using gelatin (gelatin-treated juice); (iv) enzymatic gelification of pectin by pectin methylesterase followed by natural keeving by a cider manufacturer (producer keeved juice), or (v) flotation (floated with nitrogen gas juice). The pressing of the apples led to the highly selective extraction of the flavan-3-ols with the lowest molecular weights: In the apples, the number average degree of polymerization of the flavanols was 14.7, and it dropped to 2.2 in the NCM. Keeving had the highest impact on the reduction of both flavanol content and number average degree of polymerization. The flavanol concentrations were decreased in the permeate by fining (30%) much more than by depectinization. The clarification step led to a further decrease of the number average degree of polymerization. Hydroxycinnamic acids were less affected by the extraction process (with extraction yields >50%) and not affected by clarification. The color evolved with all treatments: L*, a*, b*, and chromaticity distance index measures indicated a reduction of orange-yellow saturation except after sedimentation.

Chitin is the second most abundant polysaccharide in biomass after cellulose and the term chitosan usually refers to a family of polymers obtained after chitin deacetylation. The aim of this work was the preparation and the characterization of chitin and chitosan from the gladius (pen) of the European squid (Loligo vulgaris). A high level of deproteinization (more than 80%) was recorded using Alcalase ® with an enzyme/protein ratio of 10U/mg. The demineralization of the gladius was completely achieved within 8h at room temperature in HCl. 13 C NMR, FTIR, and XRD diffractograms of prepared chitin and chitosan were taken and then degree of deacetylation of chitosan was calculated using 13 C CP/MAS-NMR Spectroscopic. Further, in vitro antioxidant capacity of chitosan was evaluated on 1,1-diphenyl-2-picrylhydrazyl method (IC 50 =3.2mgmL -1 ) and the β-carotene bleaching assay (IC 50 =3.3mgmL -1 ). Antimicrobial activity was also investigated and assays indicated that prepared chitosan exhibited marked inhibitory activity against all microbial strains tested. Additionally, chitosan was tested such as clarifying agent for apple juice and showed powerful clarification capability, without affecting nutritional value. Furthermore, the results suggested that prepared chitosan could be used as alternative additive in pharmaceutical preparations and food industry. Copyright © 2017 Elsevier B.V. All rights reserved.

2011-01-01

In this review we outline the different mechanisms mediating hepatocarcinogenesis. We also discuss possible targets of bioactive herbal agents at different stages of hepatocarcinogenesis and highlight their role at each individual stage. We gathered information on the most common herbal prescriptions and extracts thought to be useful in prevention or sensitization for chemotherapy in management of hepatocellular carcinoma (HCC). The value of this topic may seem questionable compared to the promise offered for HCC management by chemotherapy and radiation. However, we would recommend the use of herbal preparations not as alternatives to common chemo /and or radiotherapy, but rather for prevention among at-risk individuals, given that drug/herb interactions are still in need of extensive clarification. The bioactive constituents of various herbs seem to be promising targets for isolation, cancer activity screening and clinical evaluation. Finally, herbal preparations may offer a cost effective protective alternative to individuals known to have a high risk for HCC and possibly other cancers, through maintaining cell integrity, reversing oxidative stress and modulating different molecular pathways in preventing carcinogenesis.

The aim of this study was to determine the potential of seven clarifying agents to remove pesticides in red wine. The presence of pesticides in wine consists a great problem for winemakers and therefore, results on pesticide removal by clarification are very useful for taking a decision on the appropriate adsorbent. The selection of an efficient adsorbent can be based on data correlating pesticide removal in red wine to pesticides' properties, given the great number and variety of pesticides used. So, this experimental work is focused on the collection of results with regard to pesticide removal by clarification using a great number of pesticides and fining agents. A Greek red wine, fortified with single solutions and mixtures of 23 or 9 pesticides was studied. The seven fining agents, used at two concentrations, were activated carbon, bentonite, polyvinylpolypyrrolidone (PVPP), gelatin, egg albumin, isinglass-fish glue, and casein. Pesticides were selected with a wide range of properties (octanol-water partition coefficient (log K ow ) 2.7-6.3 and water solubility 0.0002-142) and belong to 11 chemical groups. Solid phase extraction (SPE) followed by gas chromatography (GC) with electron capture detector (ECD) were performed to analyze pesticide residues of the clarified fortified wine. The correlation of the clarifying agents' effectiveness to pesticide's chemical structure and properties (log K ow , water solubility) was investigated. The antagonistic and/or synergistic effects, occurring among the pesticides in the mixtures, were calculated by indices. Pesticide removal effectiveness results of the red wine were compared to those obtained from a white wine under the same experimental conditions and discussed. The order of decreasing adsorbent effectiveness (mixture of 23 pesticides) was: activated carbon 40% > gelatin 23% > egg albumin 21% > PVPP 18% > casein 12% > bentonite 7%. Isinglass showed 12% removal at the highest permitted concentration. In the case of 9 pesticides mixture, the effectiveness was quite higher but the order remained the same compared to 23 pesticides mixture. The removal of each pesticide from its single solution was generally the highest (particularly for hydrophobic pesticides). Adsorption on fining agents is increased by increasing hydrophobicity and decreasing hydrophilicity of organic pesticide molecules.

It is a common type of cultivar in the Northern region of Nigeria and it is not susceptible to cracking. The Ibadan local variety of tomato fruits is a local variety commonly found on farmers fields in South-western region of Nigeria. They are highly susceptible to cracking. The Ibadan local variety was employed for this research. There are lots of benefits derived from the consumption of tomato fruits. The fruits can be made into tomato juice clarified with pectinases. Polygalacturonase is one of the pectinases used commercially in the clarification of fruit juice from different fruits. This study examined the production of polygalacturonase during the deterioration of tomato fruits by Aspergillus niger and the role of the purified polygalacturonase in the clarification of tomato juice. Tomato fruits of the Ibadan local variety were inoculated with mycelia discs containing spores of a 96-h-old culture of Aspergillus niger served as the inoculum. The organism from the stock culture was subcultured onto potato dextrose agar plates. The extraction of polygalacturonase after 10 days of incubation at 27 degrees C was carried out by homogenizing the fruits with liquid extractant using the MSE homogenizer after the deteriorated fruits had been chilled for 30 min inside a freezer. Control fruits were similarly treated except that sterile potato dextrose agar served as the inoculum. The effect of different temperature of incubation and different volume of enzyme on the tomato juice from the tomato fruits was investigated. Extracts from the inoculated fruits exhibited appreciable polygalacturonase activity. The juice with polygalacturonase was visually clearer and more voluminous than the juice treated with water for all parameters studied. The highest volume of juice was obtained after an incubation period of 30 min for the tomato fruits. The increase in juice yield can be attributed to the hydrolysis of pectin which releases the sap inside the cells of the pulp. The occurrence of polygalacturonase in tomato tissues infected by A. niger coupled with the trace amount in the non-infected tissues suggests that the enzyme is of fungal origin. The role of the polygalacturonase in the clarification process was established. This study will be very useful for industrial tomato juice production.

Early childhood years are the period of the greatest and most significant developments in ones’ life, and are generally regarded as the basis upon which the rest of their life is constructed. However, these early years are those that traditionally have received the least attention from environmental education. This paper was aimed to summarize several day-to-day activities that can be conducted to educate children in their early years about environment. Environmental education is an educational process that deals with the human interrelationships with the environment, and that uses an interdisciplinary problem solving approach with value clarification. Environmental education is aimed at producing a community that is knowledgeable about the biophysical environment and its associated problems, aware of how to solve these problems, and enthusiastic to work toward their solution. It highlights the progress of knowledge, understanding, attitudes, skills, and commitment for environmental problems and considerations. Further, environmental education can help children expand their ecological worldview, promote active care to the environment, and explain the relationship between modern life style and current environmental problems. Several types of environmental education have been identified from the literature, such as outdoor activities in natural outdoor setting, school gardening, play-based learning, and drawing activities. Each of these activities has its own characteristics and effects on children’s environmental-related attitudes and behaviors. Through these activities, the unique characteristics of tropical and coastal areas can potentially be used to facilitate children to learn about nature and environment. Recommendations for childhood education practitioners and future researchers are discussed.

Teaching for a practice is more than the dissemination of knowledge and information to the learner. Professional nursing education requires teachers to facilitate students' self-reflection and awareness and assimilation of core professional and personal values in order for the new nurse to anchor and internalize these values as part of a professional identity. To achieve this, nursing educators recognize the importance of learning opportunities centered in the affective domain and the importance of teaching for professional formation that supports nursing students' commitment to the values of their chosen community of practice. This paper describes the development, implementation and evaluation of a learning innovation for pre-RN students. The Power of Nursing: Embracing the Healer's Art, a five-session, 15-hour discovery model course that uses guided reflection and personal sharing is described, as are course outcomes for 68 students from four nursing schools in the U.S. Overall students' reports were strongly favorable and the learning experience was valued and identified as unique within the nursing curriculum.

The article considers the current questions of technological modeling and calculation of the new facility for cleaning natural waters, the clarifier reactor for the optimal operating mode, which was developed in Novosibirsk State University of Architecture and Civil Engineering (SibSTRIN). A calculation technique based on well-known dependences of hydraulics is presented. A calculation example of a structure on experimental data is considered. The maximum possible rate of ascending flow of purified water was determined, based on the 24 hour clarification cycle. The fractional composition of the contact mass was determined with minimal expansion of contact mass layer, which ensured the elimination of stagnant zones. The clarification cycle duration was clarified by the parameters of technological modeling by recalculating maximum possible upward flow rate of clarified water. The thickness of the contact mass layer was determined. Likewise, clarification reactors can be calculated for any other lightening conditions.

Phloem Loading through Plasmodesmata: A Biophysical Analysis1[OPEN

PubMed Central

2017-01-01

In many species, Suc en route out of the leaf migrates from photosynthetically active mesophyll cells into the phloem down its concentration gradient via plasmodesmata, i.e. symplastically. In some of these plants, the process is entirely passive, but in others phloem Suc is actively converted into larger sugars, raffinose and stachyose, and segregated (trapped), thus raising total phloem sugar concentration to a level higher than in the mesophyll. Questions remain regarding the mechanisms and selective advantages conferred by both of these symplastic-loading processes. Here, we present an integrated model—including local and global transport and kinetics of polymerization—for passive and active symplastic loading. We also propose a physical model of transport through the plasmodesmata. With these models, we predict that (1) relative to passive loading, polymerization of Suc in the phloem, even in the absence of segregation, lowers the sugar content in the leaf required to achieve a given export rate and accelerates export for a given concentration of Suc in the mesophyll and (2) segregation of oligomers and the inverted gradient of total sugar content can be achieved for physiologically reasonable parameter values, but even higher export rates can be accessed in scenarios in which polymers are allowed to diffuse back into the mesophyll. We discuss these predictions in relation to further studies aimed at the clarification of loading mechanisms, fitness of active and passive symplastic loading, and potential targets for engineering improved rates of export.

Acidic endo-polygalacturonases are the major part of pectinase preparations and extensively applied in the clarification of fruits juice, vegetables extracts, and wines. However, most of the reported fungal endo-polygalacturonases are active and stable under narrow pH range and low temperatures. In this study, an acidic endo-polygalacturonase (EPG4) was purified and characterized from a mutant strain of Penicillium oxalicum. The N-terminal amino acid sequence of EPG4 (ATTCTFSGSNGAASASKSQT) was different from those of reported endopolygalacturonases. EPG4 displayed optimal pH and temperature at 5.0 and 60-70°C towards polygalacturonic acid (PGA), respectively, and was notably stable at pH 2.2-7.0. When tested against pectins, EPG4 showed enzyme activity over a broad acidic pH range (>15.0% activity at pH 2.2-6.0 towards citrus pectin; and >26.6% activity at pH 2.2-7.0 towards apple pectin). The Km and Vmax values were determined as 1.27 mg/ml and 5,504.6 U/mg, respectively. The enzyme hydrolyzed PGA in endo-manner, releasing oligo-galacturonates from PGA, as determined by TLC. Addition of EPG4 (3.6 U/ml) significantly reduced the viscosity (by 42.4%) and increased the light transmittance (by 29.5%) of the papaya pulp, and increased the recovery (by 24.4%) of the papaya extraction. All of these properties make the enzyme a potential application in the beverage industry.

The methylotrophic yeast Pichia pastoris is a well-established expression host, which is often used in the production of protein pharmaceuticals. This work aimed to evaluate the effect of various concentrations of ascorbic acid in mixed feeding strategy with sorbitol/methanol on productivity of recombinant human growth hormone (r-hGH). The relevant concentration of ascorbic acid (5, 10, or 20 mmol) and 50 g/L sorbitol were added in batch-wise mode to the medium at the beginning of induction phase. The rate of methanol addition was increased stepwise during the first 12 h of production and then kept constant. Total protein and r-hGH concentrations were analyzed and the results compared with sorbitol/methanol feeding using one-way analysis of variance. Moreover, an effective clarification process using activated carbon was developed to remove process contaminants like pigments and endotoxins. Finally, a three-step chromatographic process was applied to purify the product. According to the obtained results, addition of 10 mmol ascorbic acid to sorbitol/methanol co-feeding could significantly increase cell biomass (1.7 fold), total protein (1.14 fold), and r-hGH concentration (1.43 fold). One percent activated carbon could significantly decrease pigments and endotoxins without any significant changes in r-hGH assay. The result of the study concluded that ascorbic acid in combination with sorbitol could effectively enhance the productivity of r-hGH. This study also demonstrated that activated carbon clarification is a simple method for efficient removal of endotoxin and pigment in production of recombinant protein in the yeast expression system.

2018-05-01

An extension of the input-output relation for a conventional Michelson interferometric gravitational-wave detector is carried out to treat an arbitrary coherent state for the injected optical beam. This extension is one of necessary researches toward the clarification of the relation between conventional gravitational-wave detectors and a simple model of a gravitational-wave detector inspired by weak-measurements in Nishizawa (2015). The derived input-output relation describes not only a conventional Michelson-interferometric gravitational-wave detector but also the situation of weak measurements. As a result, we may say that a conventional Michelson gravitational-wave detector already includes the essence of the weak-value amplification as the reduction of the quantum noise from the light source through the measurement at the dark port.

Bushnell, D.L.; Wilson, D.G.; Lieberman, L.M.

Radionuclide scintigraphy is a safe and accurate means of detecting postoperative urologic complications in renal transplant recipients. Early identification of urinary leakage coupled with aggressive intervention significantly reduces the associated morbidity and mortality. Perivesical extravasate may be difficult to distinguish from adjacent or nearby bladder activity on scintiscan. Clarification of actual bladder contour and determination of its exact location within the pelvis may resolve such uncertainties. We describe imaging techniques that define the anatomic extent of the bladder and demonstrate our scintigraphic assessment of perivesical extravasation.

Survey of possibility for volcanic energy development

NASA Astrophysics Data System (ADS)

1990-03-01

Volcanic areas, clarification of heat source structure, evaluation of resources and problems on utilization techniques were arranged to search the possibility of future volcanic heat source. It is necessary to improve the exploration accuracy by combining geophysical exploration with geological and geochemical surveys in order to explorate a magma reservoir. Especially, seismic exploration is effective. The surveying procedure is as follows: confirmation of magma existence and grasping the whole image, evaluation of resources, clarification of three-dimensional distribution of magma in a promising area, and heat structure survey by heat flow measurement and others to construct more accurate model for resources. This model is verified finally by practical drilling. Promising areas which are worthy of development, are active volcanic areas in Kyushu, Hakkoda nad Hokkaido. It is desirable to make drilling to the depth of 3 km or magma reservoir to develop the future heat source. It is also required to improve the thermal resistance and corrosion resistance of materials to be used. Heat extraction by a single well is most realistic and the closed coaxial double pipe heat exchanger or open heat exchanger in the well will be used to improve the extraction.

Dignity therapy is a novel therapeutic approach designed to decrease suffering, enhance quality of life and bolster a sense of dignity for patients approaching death. The benefits of dignity therapy were previously documented in a sample of 100 terminally ill patients. One of the products of dignity therapy is a transcript of the edited therapy session(s). In this qualitative study, 50 of the 100 (17 from Winnipeg, Manitoba, Canada, and 33 from Perth, Australia) dignity therapy transcripts were randomly drawn, and independently coded and analysed by three investigators using a grounded theory approach. The transcripts revealed that dignity therapy serves to provide a safe, therapeutic environment for patients to review the most meaningful aspects of their lives in such a manner that their core values become apparent. The most common values expressed by the patients included 'Family', 'Pleasure', 'Caring', 'A Sense of Accomplishment', 'True Friendship', and 'Rich Experience'. Exemplars of each of these values illustrate the pervasive, defining role of values in our lives. The findings are discussed in terms of values theory, the role of dignity therapy, and consideration of values clarification in clinicians' efforts to enhance the dignity of terminally ill patients.

Accumulation and breakthrough of several potentially toxic cyanobacterial species within drinking water treatment plants (DWTP) have been reported recently. The objectives of this project were to test the efficiency of different treatment barriers in cyanobacterial removal. Upon observation of cyanobacterial blooms, intensive sampling was conducted inside a full scale DWTP at raw water, clarification, filtration and oxidation processes. Samples were taken for microscopic speciation/enumeration and microcystins analysis. Total cyanobacteria cell numbers exceeded World Health Organisation and local alert levels in raw water (6,90,000 cells/mL). Extensive accumulation of cyanobacteria species in sludge beds and filters, and interruption of treatment were observed. Aphanizomenon cells were poorly coagulated and they were not trapped efficiently in the sludge. It was also demonstrated that Aphanizomenon cells passed through and were not retained over the filter. However, Microcystis, Anabaena, and Pseudanabaena cells were adequately removed by clarification and filtration processes. The breakthrough of non toxic cyanobacterial cells into DWTPs could also result in severe treatment disruption leading to plant shutdown. Application of intervention threshold values restricted to raw water does not take into consideration the major long term accumulation of potentially toxic cells in the sludge and the risk of toxins release. Thus, a sampling regime inside the plant adapted to cyanobacterial occurrence and intensity is recommended. Copyright © 2013 Elsevier Ltd. All rights reserved.

Clarification process: Resolution of decision-problem conditions

NASA Technical Reports Server (NTRS)

Dieterly, D. L.

1980-01-01

A model of a general process which occurs in both decisionmaking and problem-solving tasks is presented. It is called the clarification model and is highly dependent on information flow. The model addresses the possible constraints of individual indifferences and experience in achieving success in resolving decision-problem conditions. As indicated, the application of the clarification process model is only necessary for certain classes of the basic decision-problem condition. With less complex decision problem conditions, certain phases of the model may be omitted. The model may be applied across a wide range of decision problem conditions. The model consists of two major components: (1) the five-phase prescriptive sequence (based on previous approaches to both concepts) and (2) the information manipulation function (which draws upon current ideas in the areas of information processing, computer programming, memory, and thinking). The two components are linked together to provide a structure that assists in understanding the process of resolving problems and making decisions.

Polyelectrolyte flocculation of grain stillage for improved clarification and water recovery within bioethanol production facilities.

PubMed

Menkhaus, Todd J; Anderson, Jason; Lane, Samuel; Waddell, Evan

2010-04-01

Polyelectrolytes were investigated for flocculation of a corn whole stillage stream to improve solid-liquid clarification operations and reduce downstream utility requirements for evaporation and drying within a bioethanol process. Despite a negative zeta potential for the stillage solids, an anionic polyelectrolyte was found to provide the best flocculation. At the optimal dosage of 1.1mg polymer/g dry suspended solids, an anionic flocculant provided a clarified stream with only 0.15% w/w suspended solids (equivalent to a total dissolved solid to total suspended solid ratio greater than 40, and a viscosity reduction of 39% compared to an unflocculated "clarified" stream). The resulting solids cake had greater than 40% w/w solids, and more than 80% water recovery was found in the clarified stream. Addition of flocculant improved filtration flux by six fold and/or would allow for up to a 4-times higher flow rate if using a decanting centrifuge for clarification of corn stillage.

Becoming partners, retaining autonomy: ethical considerations on the development of precision medicine.

PubMed

Blasimme, Alessandro; Vayena, Effy

2016-11-04

Precision medicine promises to develop diagnoses and treatments that take individual variability into account. According to most specialists, turning this promise into reality will require adapting the established framework of clinical research ethics, and paying more attention to participants' attitudes towards sharing genotypic, phenotypic, lifestyle data and health records, and ultimately to their desire to be engaged as active partners in medical research.Notions such as participation, engagement and partnership have been introduced in bioethics debates concerning genetics and large-scale biobanking to broaden the focus of discussion beyond individual choice and individuals' moral interests. The uptake of those concepts in precision medicine is to be welcomed. However, as data and medical information from research participants in precision medicine cohorts will be collected on an individual basis, translating a participatory approach in this emerging area may prove cumbersome. Therefore, drawing on Joseph Raz's perfectionism, we propose a principle of respect for autonomous agents that, we reckon, can address many of the concerns driving recent scholarship on partnership and public participation, while avoiding some of the limitations these concept have in the context of precision medicine. Our approach offers a normative clarification to how becoming partners in precision is compatible with retaining autonomy.Realigning the value of autonomy with ideals of direct engagement, we show, can provide adequate normative orientation to precision medicine; it can do justice to the idea of moral pluralism by stressing the value of moral self-determination: and, finally, it can reconcile the notion of autonomy with other more communitarian values such as participation and solidarity.

Harmonizing Operas Voices. an Investigation of Different Perspectives on the Ecosystem Services Concept and Implications for Research and Practice.

NASA Astrophysics Data System (ADS)

Hermelingmeier, V.

2014-12-01

Over the past 150 years, humans have altered the planet at a rapid pace. In this new era, the Anthropocene, environmental degradation has come to a state where sustainable ecosystem management has developed into an urgent quest for humans to maintain their own life-support system. The ecosystem services (ES) concept, initially introduced as potential facilitator to manage this quest, has been criticized for its vagueness to pose a barrier to the concept's application in practice. Therefore, the focus of this paper is on this vagueness as potential barrier to successful collaboration in the research community (interdisicplinarity) as a precondition to the concept's application for sustainable ecosystem management (transdisicplinarity). Focusing on the European research project Operational Potential for Ecosystem Research Applications (OPERAs), the objective is to serve the research community with the identification of differences in conceptual perspectives on ES (differentiation), in order to recommend an effective way of handling these differences (clarification) as a basis for interdisciplinary integration (synthesis). With an emphasis on differentiation and clarification, the research process concentrates on the derivation of a typology of perspectives from the literature (RQ 1), on the basis of which perspectives in OPERAs are assessed with the help of Q methodology (RQ 2) in order to derive implications for how to handle the concept in the future (RQ 3). The main findings suggest clear differences between three foundational perspectives but a more nuanced variety of viewpoints in OPERAs that can be summarized under five main perspectives. Whereas the notion of interdisciplinarity has often steered the focus towards disciplinary worldviews as the cause for different perspectives, the results point to the insight that perspectives on the ES concept are influenced by a more complex interplay of paradigmatic assumptions. Therefore, clarification is suggested to encompass more than the standardization of discipline-induced worldviews and to require open dialogue on underlying values and ethical stances. In synthesis, the question is not only how to use the ES concept effectively but also to what extent the concept can suffice sustainable ecosystem management in the long-term.

Microbial bio-based plastics from olive-mill wastewater: Generation and properties of polyhydroxyalkanoates from mixed cultures in a two-stage pilot scale system.

The operational efficiency of a two stage pilot scale system for polyhydroxyalkanoates (PHAs) production from three phase olive oil mill wastewater (OMW) was investigated in this study. A mixed anaerobic, acidogenic culture derived from a municipal wastewater treatment plant, was used in the first stage, aiming to the acidification of OMW. The effluent of the first bioreactor that was operated in continuous mode, was collected in a sedimentation tank in which partial removal of the suspended solids was taking place, and was then forwarded to an aerobic reactor, operated in sequential batch mode under nutrient limitation. In the second stage an enriched culture of Pseudomonas sp. was used as initial inoculum for the production of PHAs from the acidified waste. Clarification of the acidified waste, using aluminium sulphate which causes flocculation and precipitation of solids, was also performed, and its effect on the composition of the acidified waste as well as on the yields and properties of PHAs was investigated. It was shown that clarification had no significant qualitative or quantitative effect on the primary carbon sources, i.e. short chain fatty acids and residual sugars, but only on the values of total suspended solids and total chemical oxygen demand of the acidified waste. The type and thermal characteristics of the produced PHAs were also similar for both types of feed. However the clarification of the waste seemed to have a positive impact on final PHAs yield, measured as gPHAs/100g of VSS, which reached up to 25%. Analysis of the final products via nuclear magnetic resonance spectroscopy revealed the existence of 3-hydroxybutyrate (3HB) and 3-hydroxyoctanoate (HO) units, leading to the conclusion that the polymer could be either a blend of P3HB and P3HO homopolymers or/and the 3HB-co-3HO co-polymer, an unusual polymer occurring in nature with advanced properties.

Steele, Martin J.

2013-01-01

The purpose of this Handbook is to provide technical information, clarification, examples, processes, and techniques to help institute good modeling and simulation practices in the National Aeronautics and Space Administration (NASA). As a companion guide to NASA-STD- 7009, Standard for Models and Simulations, this Handbook provides a broader scope of information than may be included in a Standard and promotes good practices in the production, use, and consumption of NASA modeling and simulation products. NASA-STD-7009 specifies what a modeling and simulation activity shall or should do (in the requirements) but does not prescribe how the requirements are to be met, which varies with the specific engineering discipline, or who is responsible for complying with the requirements, which depends on the size and type of project. A guidance document, which is not constrained by the requirements of a Standard, is better suited to address these additional aspects and provide necessary clarification. This Handbook stems from the Space Shuttle Columbia Accident Investigation (2003), which called for Agency-wide improvements in the "development, documentation, and operation of models and simulations"' that subsequently elicited additional guidance from the NASA Office of the Chief Engineer to include "a standard method to assess the credibility of the models and simulations."2 General methods applicable across the broad spectrum of model and simulation (M&S) disciplines were sought to help guide the modeling and simulation processes within NASA and to provide for consistent reporting ofM&S activities and analysis results. From this, the standardized process for the M&S activity was developed. The major contents of this Handbook are the implementation details of the general M&S requirements ofNASA-STD-7009, including explanations, examples, and suggestions for improving the credibility assessment of an M&S-based analysis.

Within the context of screening tests, it is important to avoid misconceptions about sensitivity, specificity, and predictive values. In this article, therefore, foundations are first established concerning these metrics along with the first of several aspects of pliability that should be recognized in relation to those metrics. Clarification is then provided about the definitions of sensitivity, specificity, and predictive values and why researchers and clinicians can misunderstand and misrepresent them. Arguments are made that sensitivity and specificity should usually be applied only in the context of describing a screening test's attributes relative to a reference standard; that predictive values are more appropriate and informative in actual screening contexts, but that sensitivity and specificity can be used for screening decisions about individual people if they are extremely high; that predictive values need not always be high and might be used to advantage by adjusting the sensitivity and specificity of screening tests; that, in screening contexts, researchers should provide information about all four metrics and how they were derived; and that, where necessary, consumers of health research should have the skills to interpret those metrics effectively for maximum benefit to clients and the healthcare system.

The objective of this work was to study the entrapped conditions of activated carbon in calcium-alginate beads for the clarification of winery wastewaters. An incomplete 3(3) factorial design was carried out to study the efficiency of activated carbon (0.5-2%); sodium alginate (1-5%); and calcium chloride (0.050-0.900 M), on the following dependent variables: colour reduction at 280, 465, 530 and 665 nm. The activated carbon and calcium chloride were the most influential variables in the colour reduction. Nearly 100% colour reductions were found for the wavelengths assayed when employing 2% of activated carbon, 5% of sodium alginate and intermediate concentrations of calcium chloride (0.475 M). Instead, other conditions like, 2% of activated carbon, 4% of sodium alginate and 0.580 M of calcium chloride can also give absorbance reductions close to 100%. Copyright © 2011 Elsevier Ltd.

International Population Assistance and Family Planning Programs: Issues for Congress

DTIC Science & Technology

2008-07-24

birth control . This policy, however, has generated contentious debate for over two decades, resulting in frequent clarification and modification of U.S. international family planning programs. In 1984, controversy arose over U.S. population aid policy when the Reagan Administration introduced restrictions, which became known as the Mexico City policy. The Mexico City policy denies U.S. funds to foreign nongovernmental organizations (NGOs) that perform or promote abortion as a method of family planning -- even if the activities are undertaken with non-U.S. funds.

Chen, Lianguo; Qian, Pei-Yuan

2017-08-28

Better understanding of the mechanisms of antifouling compounds is recognized to be of high value in establishing sensitive biomarkers, allowing the targeted optimization of antifouling compounds and guaranteeing environmental safety. Despite vigorous efforts to find new antifouling compounds, information about the mechanisms of antifouling is still scarce. This review summarizes the progress into understanding the molecular mechanisms underlying antifouling activity since 2012. Non-toxic mechanisms aimed at specific targets, including inhibitors of transmembrane transport, quorum sensing inhibitors, neurotransmission blockers, adhesive production/release inhibitors and enzyme/protein inhibitors, are put forward for natural antifouling products or shelf-stable chemicals. Several molecular targets show good potential for use as biomarkers in future mechanistic screening, such as acetylcholine esterase for neurotransmission, phenoloxidase/tyrosinase for the formation of adhesive plaques, N -acyl homoserine lactone for quorum sensing and intracellular Ca 2+ levels as second messenger. The studies on overall responses to challenges by antifoulants can be categorized as general targets, including protein expression/metabolic activity regulators, oxidative stress inducers, neurotransmission blockers, surface modifiers, biofilm inhibitors, adhesive production/release inhibitors and toxic killing. Given the current situation and the knowledge gaps regarding the development of alternative antifoulants, a basic workflow is proposed that covers the indispensable steps, including preliminary mechanism- or bioassay-guided screening, evaluation of environmental risks, field antifouling performance, clarification of antifouling mechanisms and the establishment of sensitive biomarkers, which are combined to construct a positive feedback loop.

Implicit social cognition: From measures to mechanisms

PubMed Central

Nosek, Brian A.; Hawkins, Carlee Beth; Frazier, Rebecca S.

2011-01-01

Most of human cognition occurs outside of conscious awareness or conscious control. Some of these implicit processes influence social perception, judgment and action. The last fifteen years of research in implicit social cognition can be characterized as the Age of Measurement because of a proliferation of measurement methods and research evidence demonstrating their practical value for predicting human behavior. Implicit measures assess constructs that are distinct, but related, to self-report assessments, and predict variation in behavior that is not accounted for by those explicit measures. The present state of knowledge provides a foundation for the next age of implicit social cognition – clarification of the mechanisms underlying implicit measurement and how the measured constructs influence behavior.

Bray, O.H.

This paper describes a natural language based, semantic information modeling methodology and explores its use and value in clarifying and comparing political science theories and frameworks. As an example, the paper uses this methodology to clarify and compare some of the basic concepts and relationships in the realist (e.g. Waltz) and the liberal (e.g. Rosenau) paradigms for international relations. The methodology can provide three types of benefits: (1) it can clarify and make explicit exactly what is meant by a concept; (2) it can often identify unanticipated implications and consequence of concepts and relationships; and (3) it can help inmore » identifying and operationalizing testable hypotheses.« less

Clinical utility of Aspergillus galactomannan and PCR in bronchoalveolar lavage fluid for the diagnosis of invasive pulmonary aspergillosis in patients with haematological malignancies.

Interpretation of Aspergillus galactomannan (GM) and PCR results in bronchoalveolar lavage (BAL) fluid for the diagnosis of invasive pulmonary aspergillosis (IPA) in patients with haematological malignancies requires clarification. A total of 116 patients underwent BAL for investigation of new lung infiltrates: 40% were neutropenic, 68% and 36% were receiving mould-active antifungal agents and β-lactam antibiotics. The diagnosis of proven IPA (n = 3), probable IPA (n = 15), and possible invasive fungal disease (IFD, n = 50) was made without inclusion of GM results. BAL GM (at cut-off of 0.8) had lower diagnostic sensitivity for IPA than PCR (61% versus 78%) but higher specificity (93% versus 79%). Both tests had excellent negative predictive values (85-90%), supporting their utility in excluding IPA. The use of BAL GM and PCR results increased the certainty of Aspergillus aetiology in 7 probable IPA cases where fungal hyphae were detected in respiratory samples by microscopy, and upgraded 24 patients from possible IFD to probable IPA. Use of BAL GM and PCR improves the diagnosis of IPA. Crown Copyright © 2014. Published by Elsevier Inc. All rights reserved.

N2O emissions from secondary clarifiers and their contribution to the total emissions of the WWTP.

PubMed

2014-01-01

Recent studies have indicated that the emissions of nitrous oxide, N2O, constitute a major part of the carbon footprint of wastewater treatment plants (WWTPs). Denitrification occurring in the secondary clarifier basins has been observed by many researchers, but until now N2O emissions from secondary clarifiers have not been widely reported. The objective of this study was to measure the N2O emissions from secondary clarifiers and weigh the portion they could represent of the overall emissions at WWTPs. Online measurements over several days were carried out at four different municipal WWTPs in Finland in cold weather conditions (March) and in warm weather conditions (June-July). An attempt was made to define the conditions in which N2O emissions from secondary clarifiers may occur. It was evidenced that large amounts of N2O can be emitted from the secondary clarifiers, and that the emissions have long-term variation. It was assumed that part of the N2O released in secondary clarification was originally formed in the activated sludge basin. The emissions from secondary clarification thus seem to be dependent on conditions of the nitrification and denitrification accomplished in the denitrification-nitrification process and on the amount of sludge stored in the secondary clarifiers.

Glycine, the simplest amino acid, has been intensively searched for in molecular clouds, and the comprehensive clarification of the formation path of interstellar glycine is now imperative. Among all the possible glycine formation pathways, we focused on the radical pathways revealed by Garrod (2013). In the present study, we have precisely investigated all the chemical reaction steps related to the glycine formation processes based on state-of-the-art density functional theory (DFT) calculations. We found that two reaction pathways require small activation barriers (ΔE‡ ≤ 7.75 kJ mol-1), which demonstrates the possibility of glycine formation even at low temperatures in interstellar space if the radical species are generated. The origin of carbon and nitrogen in the glycine backbone and their combination patterns are further discussed in relation to the formation mechanisms. According to the clarification of the atomic correspondence between glycine and its potential parental molecules, it is shown that the nitrogen and two carbons in the glycine can originate in three common interstellar molecules, methanol, hydrogen cyanide, and ammonia, and that the source molecules of glycine can be described by any of their combinations. The glycine formation processes can be categorized into six patterns. Finally, we discussed two other glycine formation pathways expected from the present DFT calculation results.

Samples of water and sediment from a conventional drinking-water-treatment (DWT) plant were analyzed for 113 organic compounds (OCs) that included pharmaceuticals, detergent degradates, flame retardants and plasticizers, polycyclic aromatic hydrocarbons (PAHs), fragrances and flavorants, pesticides and an insect repellent, and plant and animal steroids. 45 of these compounds were detected in samples of source water and 34 were detected in samples of settled sludge and (or) filter-backwash sediments. The average percent removal of these compounds was calculated from their average concentration in time-composited water samples collected after clarification, disinfection (chlorination), and granular-activated-carbon (GAC) filtration. In general, GAC filtration accounted for 53% of the removal of these compounds from the aqueous phase; disinfection accounted for 32%, and clarification accounted for 15%. The effectiveness of these treatments varied widely within and among classes of compounds; some hydrophobic compounds were strongly oxidized by free chlorine, and some hydrophilic compounds were partly removed through adsorption processes. The detection of 21 of the compounds in 1 or more samples of finished water, and of 3 to 13 compounds in every finished-water sample, indicates substantial but incomplete degradation or removal of OCs through the conventional DWT process used at this plant. ?? 2007 Elsevier B.V.

The aim of this study is to describe the maturation of the concept of shared governance to professional governance as a framework for structural empowerment. An analysis of the literature and concept clarification of structural empowerment and shared governance demonstrate that the concept and attributes of shared governance have evolved toward professional governance. A comprehensive, deductive literature review and concept clarification of structural empowerment, shared governance, and related constructs was completed. The concept and practice of shared governance has matured to a concept of professional governance with the attributes of accountability, professional obligation, collateral relationships, and effective decision-making.

Mind-body dualism and the compatibility of medical methods.

PubMed

Burkhardt, Hans; Imaguire, Guido

2002-01-01

In this paper we analyse some misleading theses concerning the old controversy over the relation between mind and body presented in contemporary medical literature. We undertake an epistemological clarification of the axiomatic structure of medical methods. This clarification, in turn, requires a precise philosophical explanation of the presupposed concepts. This analysis will establish two results: (1) that the mind-body dualism cannot be understood as a kind of biological variation of the subject-object dichotomy in physics, and (2) that the thesis of the incompatibility between somatic and psychosomatic medicine held by naturalists and others lacks solid epistemological foundation.

[Endoprosthesis failure in the ankle joint : Histopathological diagnostics and classification].

PubMed

Müller, S; Walther, M; Röser, A; Krenn, V

2017-03-01

Endoprostheses of the ankle joint show higher revision rates of 3.29 revisions per 100 component years. The aims of this study were the application and modification of the consensus classification of the synovia-like interface membrane (SLIM) for periprosthetic failure of the ankle joint, the etiological clarification of periprosthetic pseudocysts and a detailed measurement of proliferative activity (Ki67) in the region of osteolysis. Tissue samples from 159 patients were examined according to the criteria of the standardized consensus classification. Of these, 117 cases were derived from periprosthetic membranes of the ankle. The control group included 42 tissue specimens from the hip and knee joints. Particle identification and characterization were carried out using the particle algorithm. An immunohistochemical examination with Ki67 proliferation was performed in all cases of ankle pseudocysts and 19 control cases. The consensus classification of SLIM is transferrable to endoprosthetic failure of the ankle joint. Periprosthetic pseudocysts with the histopathological characteristics of the appropriate SLIM subtype were detectable in 39 cases of ankle joint endoprostheses (33.3%). The mean value of the Ki67 index was 14% and showed an increased proliferation rate in periprosthetic pseudocysts of the ankle (p-value 0.02037). In periprosthetic pseudocysts an above average higher detection rate of type 1 SLIM induced by abrasion (51.3%) with an increased Ki67 proliferation fraction (p-value 0.02037) was found, which can be interpreted as local destructive intraosseus synovialitis. This can be the reason for formation of pseudocystic osteolysis caused by high mechanical stress in ankle endoprostheses. A simplified diagnostic classification scoring system of dysfunctional endoprostheses of the ankle is proposed for collation of periprosthetic pseudocysts, ossifications and the Ki67 proliferation fraction.

Effects of AEA Cell-Bypass-Switch Closure on Charged EOS-Aqua NiH2 Cell

The nominal performance of AEA CBPD under simulated EOS-Aqua/Aura flight hardware configuration has been demonstrated. There is no evidence of cell rupture or excessive heat production during or after CBPD switch activation under simulated high cell impedance (open-circuit cell failure mode). Inadvertent CBPD switch activation with a charged cell (low impedance path) intermittently closes and opens up the switch, therefore the device may or may not provide protection against future open-circuit cell failure. Further testing with switches F01 and F02 may provide clarification. The formation of a continuous low impedance path (a homogeneous low melting point alloy), has been confirmed - which is the expected mode of operation.

Redox-active cerium oxide nanoparticles protect human dermal fibroblasts from PQ-induced damage.

Recently, it has been published that cerium (Ce) oxide nanoparticles (CNP; nanoceria) are able to downregulate tumor invasion in cancer cell lines. Redox-active CNP exhibit both selective pro-oxidative and antioxidative properties, the first being responsible for impairment of tumor growth and invasion. A non-toxic and even protective effect of CNP in human dermal fibroblasts (HDF) has already been observed. However, the effect on important parameters such as cell death, proliferation and redox state of the cells needs further clarification. Here, we present that nanoceria prevent HDF from reactive oxygen species (ROS)-induced cell death and stimulate proliferation due to the antioxidative property of these particles.

Krimsky, S

2001-12-01

For about a decade the term endocrine disruptor has become synonymous with a new research initiative that has been investigating the effects of hormonally active xenobiotics on biological systems. The scientific thesis behind the new research initiative is discussed and it is argued that there is a need for more emphasis on theory development and conceptual clarification that will give coherence to a field experiencing a rapid growth of empirical studies. Reflections on scientific methodology in this field will also help clarify whether endocrine disruptors symbolize a new etiology of chemically induced disease or represent variations of traditional chemical toxicology.

Mode 2 Knowledge Production in the Context of Medical Research: A Call for Further Clarifications.

PubMed

Soofi, Hojjat

2018-03-01

The traditional researcher-driven environment of medical knowledge production is losing its dominance with the expansion of, for instance, community-based participatory or participant-led medical research. Over the past few decades, sociologists of science have debated a shift in the production of knowledge from traditional discipline-based (Mode 1) to more socially embedded and transdisciplinary frameworks (Mode 2). Recently, scholars have tried to show the relevance of Mode 2 knowledge production to medical research. However, the existing literature lacks detailed clarifications on how a model of Mode 2 knowledge production can be constructed in the context of medical research. This paper calls for such further clarifications. As a heuristic means, the advocacy for a controversial experimental stem cell therapy (Stamina) is examined. It is discussed that the example cannot be considered a step towards Mode 2 medical knowledge production. Nonetheless, the example brings to the fore some complexities of medical knowledge production that need to be further examined including: (1) the shifting landscape of defining and addressing vulnerability of research participants, (2) the emerging overlap between research and practice, and (3) public health implications of revising the standard notions of quality control and accountability.

Chardonnay wines from Burgundy, obtained from musts with three levels of clarification (Low, Medium and High) during two consecutive vintages (2009 and 2010) and for two kinds of closures (screw caps and synthetic coextruded closures) were analyzed chemically and sensorially. Three bottles per turbidity level were opened in 2015 in order to assess the intensity of the reductive and/or oxidative aromas (REDOX sensory scores) by a trained sensory panel. The chemical analyses consisted in polyphenols and colloids quantification, followed by a proteomic characterization. For the two vintages, the REDOX sensory scores appeared to be driven both by the type of closure and to a lesser extent by the level of must clarification. Vintages and must racking prefermentative operations were also distinguished by chemical analyses. All white wines from the lowest must turbidity had the lowest REDOX sensory scores. Such wines exhibited lower concentrations in tyrosol and grape reaction product and higher concentrations in colloids with relatively low molecular weights. Among these macromolecules, grape proteins were also quantified, two of them exhibiting concentrations in bottled wines, which were statistically correlated to oxidative evolution in white wines

This final rule modifies the TRICARE regulation to add a definition of assistive technology (AT) devices for purposes of benefit coverage under the TRICARE Extended Care Health Option (ECHO) Program and to amend the definitions of durable equipment (DE) and durable medical equipment (DME) to better conform the language in the regulation to the statute. The final rule amends the language that specifically limits ordering or prescribing of DME to only a physician under the Basic Program, as this amendment will allow certain other TRICARE authorized individual professional providers, acting within the scope of their licensure, to order or prescribe DME. This final rule also incorporates a policy clarification relating to luxury, deluxe, or immaterial features of equipment or devices. That is, TRICARE cannot reimburse for the luxury, deluxe, or immaterial features of equipment or devices, but can reimburse for the base or basic equipment or device that meet the beneficiary's needs. Beneficiaries may choose to pay the provider for the luxury, deluxe, or immaterial features if they desire their equipment or device to have these "extra features."

2018-02-01

The type of soil material, field control, maintenance and availability of funds are several factors that must be considered in compaction of the pavement subgrade. In determining the compaction parameters in laboratory desperately requires considerable materials, time and funds, and reliable laboratory operators. If the result of soil classification values can be used to estimate the compaction parameters of a subgrade material, so it would save time, energy, materials and cost on the execution of this work. This is also a clarification (cross check) of the work that has been done by technicians in the laboratory. The study aims to estimate the compaction parameter values ie. maximum dry unit weight (γdmax) and optimum water content (Wopt) of the soil subgrade that stabilized with lime. The tests that conducted in the laboratory of soil mechanics were to determine the index properties (Fines and Liquid Limit/LL) and Standard Compaction Test. Soil samples that have Plasticity Index (PI) > 10% were made with additional 3% lime for 30 samples. By using the Goswami equation, the compaction parameter values can be estimated by equation γd max # = -0,1686 Log G + 1,8434 and Wopt # = 2,9178 log G + 17,086. From the validation calculation, there was a significant positive correlation between the compaction parameter values laboratory and the compaction parameter values estimated, with a 95% confidence interval as a strong relationship.

Population Health and Tailored Medical Care in the Home: the Roles of Home-Based Primary Care and Home-Based Palliative Care.

PubMed

Ritchie, Christine S; Leff, Bruce

2018-03-01

With the growth of value-based care, payers and health systems have begun to appreciate the need to provide enhanced services to homebound adults. Recent studies have shown that home-based medical services for this high-cost, high-need population reduce costs and improve outcomes. Home-based medical care services have two flavors that are related to historical context and specialty background-home-based primary care (HBPC) and home-based palliative care (HBPalC). Although the type of services provided by HBPC and HBPalC (together termed "home-based medical care") overlap, HBPC tends to encompass longitudinal and preventive care, while HBPalC often provides services for shorter durations focused more on distress management and goals of care clarification. Given workforce constraints and growing demand, both HBPC and HBPalC will benefit from working together within a population health framework-where HBPC provides care to all patients who have trouble accessing traditional office practices and where HBPalC offers adjunctive care to patients with high symptom burden and those who need assistance with goals clarification. Policy changes that support provision of medical care in the home, population health strategies that tailor home-based medical care to the specific needs of the patients and their caregivers, and educational initiatives to assure basic palliative care competence for all home-based medical providers will improve access and reduce illness burden to this important and underrecognized population.

The tannase (from Aspergillus niger) was immobilised by glutaraldehyde conjugation to amino-functionalised chitosan-coated magnetic nanoparticles (Fe 3 O 4 -CS nanoparticles). Fourier-transform infrared spectroscopy and thermo-gravimetric analysis showed that chitosan was coated on the surface of magnetic nanoparticles. Transmission electron microscopy indicated that the synthesised nanoparticles (Fe 3 O 4 -CS) were almost spherical or ellipsoidal with an average diameter of 5.97 ± 1.25 nm. The stability and functionality of free and immobilised tannase were compared. Both forms of tannase exhibited the same optimal temperature of 30 °C, whereas the optimal pH value of immobilised tannase (pH 4.5) was lower than that of the free tannase (pH 5.5). The pH and thermal stabilities of immobilised tannase were significantly better than those of free tannase. Immobilised tannase retained over 50% of its initial activity after repeated utilisation for eight cycles. Furthermore, the immobilised tannase effectively improve the clarity and colour of black and green tea infusions. These results showed that amino-functionalised Fe 3 O 4 -CS nanoparticles are an efficient carrier for immobilising tannase, and immobilised tannase can be used in the clarification of tea infusion.

Sweitzer, Gary L.; Anderson, Ronald D.

A meta-analysis was conducted of studies of teacher education having as measured outcomes one or more variables associated with inquiry teaching. Inquiry addresses those teacher behaviors that facilitate student acquisition of concepts and processes through strategies such as problem solving, uses of evidence, logical and analytical reasoning, clarification of values, and decision making. Studies which contained sufficient data for the calculation of an effect size were coded for 114 variables. These variables were divided into the following six major categories: study information and design characteristics, teacher and teacher trainee characteristics, student characteristics, treatment description, outcome description, and effect size calculation. A total of 68 studies resulting in 177 effect size calculations were coded. Mean effect sizes broken across selected variables were calculated.

Helicobacter pylori: fact or fiction?

1990-01-01

The recent isolation and classification of the spiral gastric bacteria Helicobacter pylori has led to an explosion of worldwide research. The data strongly suggest that H. pylori is the causative agent for type-B active chronic gastritis. The role of H. pylori in duodenal ulcer awaits clarification, and, more importantly, potential treatment regimens need clear documentation and further detailed research. The past decade has revealed many intriguing facts about H. pylori infection. If, during the 1990s, eradication of H. pylori by means of appropriate and safe medication can lead to the control and prevention of gastroduodenal disease, then major clinical and economic benefits can be anticipated.

Adipokines and Hepatic Insulin Resistance

PubMed Central

Hassan, Waseem

2013-01-01

Obesity is a major risk factor for insulin resistance and type 2 diabetes. Adipose tissue is now considered to be an active endocrine organ that secretes various adipokines such as adiponectin, leptin, resistin, tumour necrosis factor-α, and interleukin-6. Recent studies have shown that these factors might provide a molecular link between increased adiposity and impaired insulin sensitivity. Since hepatic insulin resistance plays the key role in the whole body insulin resistance, clarification of the regulatory processes about hepatic insulin resistance by adipokines in rodents and human would seem essential in order to understand the mechanism of type 2 diabetes and for developing novel therapeutic strategies to treat it.

Thiolate-bridged diiron compounds that are related to the active site of the [Fe-Fe] hydrogenase enzyme have been shown to act as electrocatalysts for reduction of protons. The use of XAFS for clarification of the structures of intermediates formed following reduction of related diiron carbonyl compounds is described. These measurements allow the determination of Fe-Fe and Fe-S bond lengths with good reliability and when used in conjunction with the standard bonding models this provides a means of validating the structures proposed for longer-lived ( t>20 s at -50 °C) reaction intermediates.

Mechanical Behavior of Spray-Coated Metallic Laminates

Vackel, Andrew; Nakamura, Toshio; Sampath, Sanjay

2016-06-01

Thermal spray (TS) coatings have been extensively utilized for various surface modifications such as enhancing wear/erosion resistance and thermal protection. In the present study, a new function of TS material is explored by studying its load-carrying capability. Due to the inherent microstructures containing voids and interfaces, it has been presumed TS materials were not suitable to bear loads. However, the recent advances in TS technology to manufacture near fully dense TS coatings have expanded their potential applications. In the current experiments, TS nickel coatings are deposited onto metallic substrates, and their mechanical behaviors are closely examined. Based on the measured data, the estimated elastic modulus of TS Ni is about 130 GPa (35% less than bulk value), and the maximum tensile strength is about 500 MPa (comparable to bulk value). It was found that such a high value is attainable because the coating is deposited onto a substrate, enabling a load-transfer mechanism and preventing coating failure at a much lower stress level. Three distinct deformation stages are identified to describe this behavior. Such a clarification is critical for enabling TS process to restore structural parts as well as to additively manufacture load-bearing components.

Sharing methodology: a worked example of theoretical integration with qualitative data to clarify practical understanding of learning and generate new theoretical development.

Theoretical integration is a necessary element of study design if clarification of experiential learning is to be achieved. There are few published examples demonstrating how this can be achieved. This methodological article provides a worked example of research methodology that achieved clarification of authentic early experiences (AEEs) through a bi-directional approach to theory and data. Bi-directional refers to our simultaneous use of theory to guide and interrogate empirical data and the use of empirical data to refine theory. We explain the five steps of our methodological approach: (1) understanding the context; (2) critique on existing applications of socio-cultural models to inform study design; (3) data generation; (4) analysis and interpretation and (5) theoretical development through a novel application of Metis. These steps resulted in understanding of how and why different outcomes arose from students participating in AEE. Our approach offers a mechanism for clarification without which evidence-based effective ways to maximise constructive learning cannot be developed. In our example it also contributed to greater theoretical understanding of the influence of social interactions. By sharing this example of research undertaken to develop both theory and educational practice we hope to assist others seeking to conduct similar research.

Effective doctor-patient communication, including a shared understanding, is associated with treatment adherence across medicine. However, communication is affected by a diagnosis of schizophrenia and reaching a shared understanding can be challenging. During conversation, people detect and deal with possible misunderstanding using a conversational process called repair. This study tested the hypothesis that more frequent repair in psychiatrist-patient communication is associated with better treatment adherence in schizophrenia. Routine psychiatric consultations involving patients with (DSM-IV) schizophrenia or schizoaffective disorder were audio-visually recorded. Consultations were coded for repair and patients' symptoms and insight assessed. Adherence was assessed six months later. A principal components analysis reduced the repair data for further analysis. Random effects models examined the association between repair and adherence, adjusting for symptoms, consultation length and the amount patients spoke. 138 consultations were recorded, 118 were followed up. Patients requesting clarification of the psychiatrist's talk and the clarification provided by the psychiatrist was associated with adherence six months later (OR 5.82, 95% CI 1.31-25.82, p=0.02). The quality of doctor-patient communication also appears to influence adherence in schizophrenia. Future research should investigate how patient clarification can be encouraged among patients and facilitated by psychiatrists' communication. Copyright © 2013 The Authors.

This study focused on the volatile changes in cv. Verdeal Transmontana throughout the entire olive oil processing chain, from the drupe to olive oil storage up to 12 months, while correlating it with quality parameters and sensory quality. During crushing and malaxation, the volatiles formed were mainly "green-leaf volatiles" (GLVs), namely (E)-2-hexenal, hexanal, and 1-hexanol. Centrifugation and clarification steps increased the total volatile amounts to 130 mg kg -1 . However, clarification also increased nonanal and (E)-2-decenal contents, two markers of oxidation, with a noticeable loss of phenolic compounds and oxidative stability. During storage, the total volatile amounts reduced drastically (94% at 12 months after extraction), together with the positive sensory attributes fruity, green, bitter, and pungent. Despite being classified as extra-virgin after one year of storage, peroxides and conjugated dienes were significantly higher while there was a reduction in antioxidant capacity as well as in phenolic compounds (less 50%) and oxidative stability (57%). The present work allowed concluding that the extraction process modulates the volatile composition of olive oil, with a concentration of volatiles at the clarification step. During storage, volatiles are lost, mainly eight months after extraction, leading to the loss of important sensory attributes. Copyright © 2018 Elsevier Ltd. All rights reserved.

Exercise therapy in polycystic ovary syndrome.

PubMed

Hoeger, Kathleen M

2008-01-01

Women with polycystic ovary syndrome (PCOS) demonstrate a high prevalence of obesity across all populations studied. The role of decreased energy expenditure through reduced physical activity in contributing to obesity in PCOS is not well studied. The independent benefits of exercise in improving metabolic disease, cardiovascular health, and diabetes have been shown in the general population. Moderate activity incorporated into daily activities appears to be as effective in the reduction in diabetes risk and cardiovascular disease as that achieved with vigorous activity and may be more sustainable over the long-term. The role of physical activity in the management of the reproductive dysfunction of PCOS is less established, although lifestyle change incorporating increased physical activity with reduced caloric intake has shown benefit in small published trials. Studies of weight loss demonstrate an essential role for increased physical activity in maintenance of weight loss over the long-term although minimal effect in the achievement of weight loss with exercise alone. Further studies of the role for exercise in the management of reproductive dysfunction in PCOS as well as clarification of the type, frequency, and duration of exercise to achieve the best outcomes are needed.

This study investigates gaze behaviour in child dialogues. In earlier studies the authors have investigated the use of requests for clarification and responses in order to study the co-creation of understanding in a referential communication task. By adding eye tracking, this line of research is now expanded to include non-verbal contributions in conversation. To investigate the timing of gazes in face-to-face interaction and to relate the gaze behaviour to the use of requests for clarification. Eight conversational pairs of typically developing 10-15 year olds participated. The pairs (director and executor) performed a referential communication task requiring the description of faces. During the dialogues both participants wore head-mounted eye trackers. All gazes were recorded and categorized according to the area fixated (Task, Face, Off). The verbal context for all instances of gaze at the partner's face was identified and categorized using time-course analysis. The results showed that the executor spends almost 90% of the time fixating the gaze on the task, 10% on the director's face and less than 0.5% elsewhere. Turn shift, primarily requests for clarification, and back channelling significantly predicted the executors' gaze to the face of the task director. The distribution of types of requests showed that requests for previously unmentioned information were significantly more likely to be associated with gaze at the director. The study shows that the executors' gaze at the director accompanies important dynamic shifts in the dialogue. The association with requests for clarification indicates that gaze at the director can be used to monitor the response with two modalities. Furthermore, the significantly higher association with requests for previously unmentioned information indicates that gaze may be used to emphasize the verbal content. The results will be used as a reference for studies of gaze behaviour in clinical populations with hearing and language impairments. © 2012 Royal College of Speech and Language Therapists.

Analysis of estrogenic activity in environmental waters in Rio de Janeiro state (Brazil) using the yeast estrogen screen.

The estrogenicity of waters collected from an important hydrological system in Brazil (Paraiba do Sul and Guandu Rivers) was assessed using the yeast estrogen screen (YES) assay. Sampling was performed in rivers and at the outlets of conventional water treatment plants (WTP). The removal of estrogenic activity by ozonation and chlorination after conventional water treatment (clarification and sand filtration) was investigated employing samples of the Guandu River spiked with estrogens and bisphenol A (BPA). The results revealed a preoccupying incidence of estrogenic activity at levels higher than 1ngL(-1) along some points of the rivers. Another matter of concern was the number of samples from WTPs presenting estrogenicity surpassing 1ngL(-1). The oxidation techniques (ozonation and chlorination) were effective for the removal of estrogenic activity and the combination of both techniques led to good results using less amounts of oxidants.

Confocal laser-scanning microscopy is a useful tool for visualizing neurons and glia in transparent preparations of brain tissue from laboratory animals. Currently, imaging capillaries and venules in transparent brain tissues requires the use of fluorescent proteins. Here, we show that vessels can be imaged by confocal laser-scanning microscopy in transparent cortical, hippocampal and cerebellar preparations after clarification of China ink-injected specimens by the Spalteholz method. This method may be suitable for global, three-dimensional, quantitative analyses of vessels, including stereological estimations of total volume and length and of surface area of vessels, which constitute indirect approaches to investigate angiogenesis. © 2017 Anatomical Society.

When knowledge activated from memory intrudes on probabilistic inferences from description - the case of stereotypes.

PubMed

Dorrough, Angela R; Glöckner, Andreas; Betsch, Tilmann; Wille, Anika

2017-10-01

To make decisions in probabilistic inference tasks, individuals integrate relevant information partly in an automatic manner. Thereby, potentially irrelevant stimuli that are additionally presented can intrude on the decision process (e.g., Söllner, Bröder, Glöckner, & Betsch, 2014). We investigate whether such an intrusion effect can also be caused by potentially irrelevant or even misleading knowledge activated from memory. In four studies that combine a standard information board paradigm from decision research with a standard manipulation from social psychology, we investigate the case of stereotypes and demonstrate that stereotype knowledge can yield intrusion biases in probabilistic inferences from description. The magnitude of these biases increases with stereotype accessibility and decreases with a clarification of the rational solution. Copyright © 2017 Elsevier B.V. All rights reserved.

Reply [to “Comment on ‘Federal funding at a time of budget austerity’”

Press, Frank

National laboratories are indeed engaged in many educational activities, particularly those with close connections to universities. These activities are especially strong where they are linked to unique facilities or programs, which many are. The NRC report urges greater discipline in assessing their quality and role in education and training, but those institutions that have maintained high quality and that do indeed help educate the next generation about science and technology would fare well under the kind of review proposed. The report urges that federal laboratories focus on mission requirements. It also recommends that federal funding “generally favor” academic institutions. To the extent that some national laboratories function as “academic institutions” in the senses noted in the report, they should not only survive, but prosper. A few clarifications may be useful.

Beer Clarification by Novel Ceramic Hollow-Fiber Membranes: Effect of Pore Size on Product Quality.

PubMed

Cimini, Alessio; Moresi, Mauro

2016-10-01

In this work, the crossflow microfiltration performance of rough beer samples was assessed using ceramic hollow-fiber (HF) membrane modules with a nominal pore size ranging from 0.2 to 1.4 μm. Under constant operating conditions (that is, transmembrane pressure difference, TMP = 2.35 bar; feed superficial velocity, v S = 2.5 m/s; temperature, T = 10 °C), quite small steady-state permeation fluxes (J * ) of 32 or 37 L/m 2 /h were achieved using the 0.2- or 0.5-μm symmetric membrane modules. Both permeates exhibited turbidity <1 EBC unit, but a significant reduction in density, viscosity, color, extract, and foam half-life with respect to their corresponding retentates. The 0.8-μm asymmetric membrane module might be selected, its corresponding permeate having quite a good turbidity and medium reduction in the aforementioned beer quality parameters. Moreover, it exhibited J * values of the same order of magnitude of those claimed for the polyethersulfone HF membrane modules currently commercialized. The 1.4-μm asymmetric membrane module yielded quite a high steady-state permeation flux (196 ± 38 L/m 2 /h), and a minimum decline in permeate quality parameters, except for the high levels of turbidity at room temperature and chill haze. In the circumstances, such a membrane module might be regarded as a real valid alternative to conventional powder filters on condition that the resulting permeate were submitted to a final finishing step using 0.45- or 0.65-μm microbially rated membrane cartridges prior to aseptic bottling. A novel combined beer clarification process was thus outlined. © 2016 Institute of Food Technologists®.

Philosophy of clinical psychopharmacology.

PubMed

Aragona, Massimiliano

2013-03-01

The renewal of the philosophical debate in psychiatry is one exciting news of recent years. However, its use in psychopharmacology may be problematic, ranging from self-confinement into the realm of values (which leaves the evidence-based domain unchallenged) to complete rejection of scientific evidence. In this paper philosophy is conceived as a conceptual audit of clinical psychopharmacology. Its function is to criticise the epistemological and methodological problems of current neopositivist, ingenuously realist and evidence-servant psychiatry from within the scientific stance and with the aim of aiding psychopharmacologists in practicing a more self-aware, critical and possibly useful clinical practice. Three examples are discussed to suggest that psychopharmacological practice needs conceptual clarification. At the diagnostic level it is shown that the crisis of the current diagnostic system and the problem of comorbidity strongly influence psychopharmacological results, new conceptualizations more respondent to the psychopharmacological requirements being needed. Heterogeneity of research samples, lack of specificity of psychotropic drugs, difficult generalizability of results, need of a phenomenological study of drug-induced psychopathological changes are discussed herein. At the methodological level the merits and limits of evidence-based practice are considered, arguing that clinicians should know the best available evidence but that guidelines should not be constrictive (due to several methodological biases and rhetorical tricks of which the clinician should be aware, sometimes respondent to extra-scientific, economical requests). At the epistemological level it is shown that the clinical stance is shaped by implicit philosophical beliefs about the mind/body problem (reductionism, dualism, interactionism, pragmatism), and that philosophy can aid physicians to be more aware of their beliefs in order to choose the most useful view and to practice coherently. In conclusion, psychopharmacologists already use methodological audit (e.g. statistical audit); similarly, conceptual clarification is needed in both research planning/evaluation and everyday psychopharmacological practice.

Change Mechanisms of Schema-Centered Group Psychotherapy with Personality Disorder Patients

Tschacher, Wolfgang; Zorn, Peter; Ramseyer, Fabian

2012-01-01

Background This study addressed the temporal properties of personality disorders and their treatment by schema-centered group psychotherapy. It investigated the change mechanisms of psychotherapy using a novel method by which psychotherapy can be modeled explicitly in the temporal domain. Methodology and Findings 69 patients were assigned to a specific schema-centered behavioral group psychotherapy, 26 to social skills training as a control condition. The largest diagnostic subgroups were narcissistic and borderline personality disorder. Both treatments offered 30 group sessions of 100 min duration each, at a frequency of two sessions per week. Therapy process was described by components resulting from principal component analysis of patients' session-reports that were obtained after each session. These patient-assessed components were Clarification, Bond, Rejection, and Emotional Activation. The statistical approach focused on time-lagged associations of components using time-series panel analysis. This method provided a detailed quantitative representation of therapy process. It was found that Clarification played a core role in schema-centered psychotherapy, reducing rejection and regulating the emotion of patients. This was also a change mechanism linked to therapy outcome. Conclusions/Significance The introduced process-oriented methodology allowed to highlight the mechanisms by which psychotherapeutic treatment became effective. Additionally, process models depicted the actual patterns that differentiated specific diagnostic subgroups. Time-series analysis explores Granger causality, a non-experimental approximation of causality based on temporal sequences. This methodology, resting upon naturalistic data, can explicate mechanisms of action in psychotherapy research and illustrate the temporal patterns underlying personality disorders. PMID:22745811

Oxidative stress and mechanisms of ochronosis in alkaptonuria.

PubMed

Braconi, Daniela; Millucci, Lia; Bernardini, Giulia; Santucci, Annalisa

2015-11-01

Alkaptonuria (AKU) is a rare metabolic disease due to a deficient activity of the enzyme homogentisate 1,2-dioxygenase (HGD), involved in Phe and Tyr catabolism. Due to such a deficiency, AKU patients undergo accumulation of the metabolite homogentisic acid (HGA), which is prone to oxidation/polymerization reactions causing the production of a melanin-like pigment. Once the pigment is deposited onto connective tissues (mainly in joints, spine, and cardiac valves), a classical bluish-brown discoloration is imparted, leading to a phenomenon known as "ochronosis", the hallmark of AKU. A clarification of the molecular mechanisms for the production and deposition of the ochronotic pigment in AKU started only recently with a range of in vitro and ex vivo human models used for the study of HGA-induced effects. Thanks to redox-proteomic analyses, it was found that HGA could induce significant oxidation of a number of serum and chondrocyte proteins. Further investigations allowed highlighting how HGA-induced proteome alteration, lipid peroxidation, thiol depletion, and amyloid production could contribute to oxidative stress generation and protein oxidation in AKU. This review briefly summarizes the most recent findings on HGA-induced oxidative stress in AKU, helping in the clarification of the molecular mechanisms of ochronosis and potentially providing the basis for its pharmacological treatment. Future work should be undertaken in order to validate in vivo the results so far obtained in in vitro AKU models. Copyright © 2015 Elsevier Inc. All rights reserved.

Removal of famoxadone, fluquinconazole and trifloxystrobin residues in red wines: effects of clarification and filtration processes.

Oliva, Jose; Payá, Paula; Cámara, Miguel Angel; Barba, Alberto

2007-01-01

The effects of six clarification agents [egg albumin, blood albumin, bentonite + gelatine, charcoal, polyvinylpolypyrrolidine (PVPP) and silica gel] on the removal of residues of three fungicides (famoxadone, fluquinconazole and trifloxystrobin) applied directly to a racked red wine, elaborated from Monastrell variety grapes from the D.O. Region of Jumilla (Murcia, Spain) were studied. The clarified wines were filtered with 0.45 microm nylon filters to determine the influence of this winemaking process in the disappearance of fungicide residues. Analytical determination of fluquinconazole and trifloxystrobin was performed by gas chromatography with electron captor detector (ECD), while that of famoxadone using an HPLC equipped with a diode array detector (DAD). Generally, trifloxystrobin is the fungicide that is the lowest persistent one in wines, except in the egg albumin study whereas, the most persistent one is fluquinconazole. The elimination depends on the nature of the active ingredient, though the water stability in the presence of light within it has more influence than the solubility and polarity of the product itself. The most effective clarifying agents were the charcoal and PVPP. The silica gel and bentonite plus gelatine were not enough to reduce considerably the residual contents in the wine clarified with them. In general terms, filtration is not an effective step in the elimination of wine residues. The greatest removal after filtration is obtained in wines clarified with egg albumine and bentonite plus gelatine, and the lowest in those clarified with PVPP.

Rethinking organisations: a feminist perspective.

PubMed

Rao, A; Stuart, R

1997-02-01

Organizational transformation was the theme of a 1996 meeting in Canada of men and women from Asia, Africa, Latin America, North America, and Europe concerned with more equitable power relations between men and women. Gender parity policies and initiatives are necessary but not sufficient as long as the organizational culture remains antithetical to gender equality and adequate resources are withheld. Three salient structural aspects of organizations were identified by participants: the expectation that staff should place their employment rather than family at the center of their lives, a view of power as a finite resource linked with control and hierarchy, and a tendency to focus narrowly on a single purpose and course of action. Recommended, to change these factors, were linkage of the feminist goal of social transformation to the espoused values of the organization, clarification of the multiple meanings attached to the concept of gender and their implications for different organizational contexts, identification of instances of dissonance between an organization's stated values and its actual culture (e.g., pressure on employees to work long hours, to the detriment of family), and an emphasis on process as well as outcome.

Concepts of animal welfare in relation to positions in animal ethics.

PubMed

Schmidt, Kirsten

2011-06-01

When animal ethicists deal with welfare they seem to face a dilemma: On the one hand, they recognize the necessity of welfare concepts for their ethical approaches. On the other hand, many animal ethicists do not want to be considered reformist welfarists. Moreover, animal welfare scientists may feel pressed by moral demands for a fundamental change in our attitude towards animals. The analysis of this conflict from the perspective of animal ethics shows that animal welfare science and animal ethics highly depend on each other. Welfare concepts are indispensable in the whole field of animal ethics. Evidence for this can be found by analyzing the structure of theories of animal ethics and the different ways in which these theories employ welfare concepts. Furthermore, the background of values underneath every welfare theory is essential to pursue animal welfare science. Animal ethics can make important contributions to the clarification of underlying normative assumptions with regard to the value of the animal, with regard to ideas about what is valuable for the animal, and with regard to the actions that should follow from the results of animal welfare science.

Two guidelines from the American College of Cardiology (ACC), the American Heart Association (AHA), and collaborating societies address the risk of aortic dissection in patients with bicuspid aortic valves and severe aortic enlargement: the "2010 ACCF/AHA/AATS/ACR/ASA/SCA/SCAI/SIR/STS/SVM Guidelines for the Diagnosis and Management of Patients With Thoracic Aortic Disease" (Circulation. 2010;121:e266-e369) and the "2014 AHA/ACC Guideline for the Management of Patients With Valvular Heart Disease" (Circulation. 2014;129:e521-e643). However, the 2 guidelines differ with regard to the recommended threshold of aortic root or ascending aortic dilatation that would justify surgical intervention in patients with bicuspid aortic valves. The ACC and AHA therefore convened a subcommittee representing members of the 2 guideline writing committees to review the evidence, reach consensus, and draft a statement of clarification for both guidelines. This statement of clarification uses the ACC/AHA revised structure for delineating the Class of Recommendation and Level of Evidence to provide recommendations that replace those contained in Section 9.2.2.1 of the thoracic aortic disease guideline and Section 5.1.3 of the valvular heart disease guideline. © 2015 American College of Cardiology Foundation and American Heart Association, Inc.

Feature Visibility Limits in the Non-Linear Enhancement of Turbid Images

Jobson, Daniel J.; Rahman, Zia-ur; Woodell, Glenn A.

2003-01-01

The advancement of non-linear processing methods for generic automatic clarification of turbid imagery has led us from extensions of entirely passive multiscale Retinex processing to a new framework of active measurement and control of the enhancement process called the Visual Servo. In the process of testing this new non-linear computational scheme, we have identified that feature visibility limits in the post-enhancement image now simplify to a single signal-to-noise figure of merit: a feature is visible if the feature-background signal difference is greater than the RMS noise level. In other words, a signal-to-noise limit of approximately unity constitutes a lower limit on feature visibility.

Molecular mechanisms underlying PINK1 and Parkin catalyzed ubiquitylation of substrates on damaged mitochondria.

PubMed

Koyano, Fumika; Matsuda, Noriyuki

2015-10-01

PINK1 and Parkin are gene products that cause genetic recessive Parkinsonism. PINK1 is a protein kinase and Parkin is a ubiquitin ligase (E3) that links ubiquitin to a substrate. Importantly, under steady state conditions, the enzymatic activity of Parkin is completely suppressed, but is activated when mitochondria become abnormal. In 2013 and 2014, biochemical and structure-function analyses revealed a number of critical mechanistic insights. First, Parkin is a self-inhibitory E3 that suppresses its E3 activity via intramolecular interactions. Second, in response to a decrease in mitochondrial membrane potential, PINK1 phosphorylates Ser65 in both the Parkin ubiquitin-like domain and ubiquitin itself. These phosphorylation events cooperate to relieve the Parkin autoinhibition. Third, activated Parkin forms a ubiquitin-thioester bond at Cys431 to produce a reaction intermediate that catalyzes ubiquitylation of substrates on damaged mitochondria. While the molecular mechanism regulating Parkin enzymatic activity has largely eluded clarification, a complete picture is now emerging. Copyright © 2015 Elsevier B.V. All rights reserved.

A novel endo-polygalacturonase (endo-PG I) from Achaetomium sp. Xz8 was identified, overexpressed in Pichia pastoris, and characterized in this report. Recombinant endo-PG I is distinguished from other enzyme counterparts by its high activity towards polygalacturonic acid (49,934 U/ml) and high yield in the 15-l fermentor (2.13 g/l). It exhibits optimal activity at 45 °C and remained active over a broad temperature range of 0-80 °C. Distinct from most fungal polygalacturonases that have acidic pH optima, endo-PG I is optimally active at pH 6, similar to the pH of fresh papaya juice (5.7). Endo-PG I alone reduced the viscosity of papaya juice by 17.6%, and increased its transmittance by 59.1%. When combined with a commercial pectin methylesterase, it showed much higher efficiency with a synergy degree of more than 1.25. All these favourable enzymatic properties make endo-PG I attractive for potential applications in the juice industry. Copyright © 2013 Elsevier Ltd. All rights reserved.

The complex patient: A concept clarification.

PubMed

Manning, Eli; Gagnon, Marilou

2017-03-01

Over the last decade, the concept of the "complex patient" has not only been more widely used in multidisciplinary healthcare teams and across various healthcare disciplines, but it has also become more vacuous in meaning. The uptake of the concept of the "complex patient" spans across disciplines, such as medicine, nursing, and social work, with no consistent definition. We review the chronological evolution of this concept and its surrogate terms, namely "comorbidity," "multimorbidity," "polypathology," "dual diagnosis," and "multiple chronic conditions." Drawing on key principles of concept clarification, we highlight disciplinary usage in the literature published between 2005 and 2015 in health sciences, attending to overlaps and revealing nuances of the complex patient concept. Finally, we discuss the implications of this concept for practice, research, and theory. © 2017 John Wiley & Sons Australia, Ltd.

A Practical Clinical Approach to Diagnosis of Fetal Alcohol Spectrum Disorders: Clarification of the 1996 Institute of Medicine Criteria

Background. The adverse effects of alcohol on the developing human represent a spectrum of structural anomalies and behavioral and neurocognitive disabilities, most accurately termed fetal alcohol spectrum disorders (FASD). The first descriptions in the modern medical literature of a distinctly recognizable pattern of malformations associated with maternal alcohol abuse were reported in 1968 and 1973. Since that time, substantial progress has been made in developing specific criteria for defining and diagnosing this condition. Two sets of diagnostic criteria are now used most widely for evaluation of children with potential diagnoses in the FASD continuum, ie, the 1996 Institute of Medicine (IOM) criteria and the Washington criteria. Although both approaches have improved the clinical delineation of FASD, both suffer from significant drawbacks in their practical application in pediatric practice. Objective. The purpose of this report is to present specific clarifications of the 1996 IOM criteria for the diagnosis of FASD, to facilitate their practical application in clinical pediatric practice. Methods. A large cohort of children who were prenatally exposed to alcohol were identified, through active case-ascertainment methods, in 6 Native American communities in the United States and 1 community in the Western Cape Province of South Africa. The children and their families underwent standardized multidisciplinary evaluations, including a dysmorphology examination, developmental and neuropsychologic testing, and a structured maternal interview, which gathered data about prenatal drinking practices and other demographic and family information. Data for these subjects were analyzed, and revisions and clarifications of the existing IOM FASD diagnostic categories were formulated on the basis of the results. Results. The revised IOM method defined accurately and completely the spectrum of disabilities among the children in our study. On the basis of this experience, we propose specific diagnostic criteria for fetal alcohol syndrome and partial fetal alcohol syndrome. We also define alcohol-related birth defects and alcohol-related neurodevelopmental disorder from a practical standpoint. Conclusions. The 1996 IOM criteria remain the most appropriate diagnostic approach for children prenatally exposed to alcohol. The proposed revisions presented here make these criteria applicable in clinical pediatric practice.

Identification and clarification of the role of key active site residues in bacterial glutathione S-transferase zeta/maleylpyruvate isomerase

Highlights: {yields} Application of site-directed mutagenesis to probe the active site residues of glutathione-dependent maleylpyruvate isomerase. {yields} Two conserved residues, Arg8 and Arg176, in zeta class glutathione S-transferases are critical for maleylpyruvate orientation and enolization. {yields} Arg109, found exclusively in NagL, participates in k{sub cat} regulation. {yields} The T11A mutant exhibited a significantly decreased K{sub m} value for glutathione with little impact on maleylpyruvate kinetics. {yields} The Thr11 residue appears to have significance in the evolution of glutathione S-transferase classes. -- Abstract: The maleylpyruvate isomerase NagL from Ralstonia sp. strain U2, which has been structurally characterized previously, catalyzes the isomerizationmore » of maleylpyruvate to fumarylpyruvate. It belongs to the class zeta glutathione S-transferases (GSTZs), part of the cytosolic GST family (cGSTs). In this study, site-directed mutagenesis was conducted to probe the functions of 13 putative active site residues. Steady-state kinetic information for mutants in the reduced glutathione (GSH) binding site, suggested that (a) Gln64 and Asp102 interact directly with the glutamyl moiety of glutathione, (b) Gln49 and Gln64 are involved in a potential electron-sharing network that influences the ionization of the GSH thiol. The information also suggests that (c) His38, Asn108 and Arg109 interact with the GSH glycine moiety, (d) His104 has a role in the ionization of the GSH sulfur and the stabilization of the maleyl terminal carboxyl group in the reaction intermediate and (e) Arg110 influences the electron distribution in the active site and therefore the ionization of the GSH thiolate. Kinetic data for mutants altered in the substrate-binding site imply that (a) Arg8 and Arg176 are critical for maleylpyruvate orientation and enolization, and (b) Arg109 (exclusive to NagL) participates in k{sub cat} regulation. Surprisingly, the T11A mutant had a decreased GSH K{sub m} value, whereas little impact on maleylpyruvate kinetics was observed, suggesting that this residue plays an important role in GSH binding. An evolutionary trend in this residue appears to have developed not only in prokaryotic and eukaryotic GSTZs, but also among the wider class of cGSTs.« less

Early T-cell activation biophysics

PubMed Central

Henry, Nelly; Hivroz, Claire

2009-01-01

The T-cell is one of the main players in the mammalian immune response. It ensures antigen recognition at the surface of antigen-presenting cells in a complex and highly sensitive and specific process, in which the encounter of the T-cell receptor with the agonist peptide associated with the major histocompatibility complex triggers T-cell activation. While signaling pathways have been elucidated in increasing detail, the mechanism of TCR triggering remains highly controversial despite active research published in the past 10 years. In this paper, we present a short overview of pending questions on critical initial events associated with T-cell triggering. In particular, we examine biophysical approaches already in use, as well as future directions. We suggest that the most recent advances in fluorescence super-resolution imaging, coupled with the new classes of genetic fluorescent probes, will play an important role in elucidation of the T-cell triggering mechanism. Beyond this aspect, we predict that exploration of mechanical cues in the triggering process will provide new clues leading to clarification of the entire mechanism. PMID:20514131

The covalent binding of pectinase onto amino functionalized silica-coated magnetic nanoparticles (CSMNPs) through glutaraldehyde activation was investigated for nanobiocatalyst fabrication. The average particle size and morphology of the nanoparticles were characterized using transmission electron microscopy (TEM). The statistical analysis for TEM image suggests that the coating and binding process did not cause any significant change in size of MNPs. The morphological and phase change of the magnetic nanoparticles (MNPs) after various coatings and immobilization were characterized by X-ray diffraction (XRD) studies. The various surface modifications and pectinase binding onto nanoparticles were confirmed by Fourier transform infrared (FT-IR) spectroscopy. The maximum activity of immobilized pectinase was obtained at its weight ratio of 19.0×10(-3) mg bound pectinase/mg CSMNPs. The pH, temperature, reusability, storage ability and kinetic studies were established to monitor their improved stability and activity of the fabricated nanobiocatalyst. Furthermore, the application was extended in the clarification of Malus domestica juice. Copyright © 2013 Elsevier B.V. All rights reserved.

Beyond Brainstorming: Exploring Convergence in Teams.

Seeber, Isabella; de Vreede, Gert-Jan; Maier, Ronald; Weber, Barbara

2017-01-01

Collaborative brainstorming is often followed by a convergence activity where teams extract the most promising ideas on a useful level of detail from the brainstorming results. Contrary to the wealth of research on electronic brainstorming, there is a dearth of research on convergence. We used experimental methods for an in-depth exploration of two facilitation-based interventions in a convergence activity: attention guidance (focusing participants on procedures to execute a convergence task) and discussion encouragement (engaging participants in conversations to combine knowledge on ideas). Our findings show that both attention guidance and discussion encouragement are correlated with higher convergence quality. We argue that attention guidance's contribution is in its support of coordination, information processing, and goal specification. Similar, we argue that discussion encouragement's contribution is in its stimulation of idea clarification and idea combination. Contrary to past research, our findings further show that satisfaction was higher after convergence than after brainstorming.

Effective flocculation of fine mineral suspensions using Moringa oleifera seeds

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pickett, T.M.

1995-12-31

The purpose of this research was to investigate the feasibility of using Moringa oleifera seeds, or the active components of the seeds, in the clarification of waters containing suspended mineral fines. In comparative testing using a hematite suspension, the flocculating activity of Moringa oleifera seeds was better than alum. Twenty milligrams of seed powder was sufficient to clarify the hematite to near zero turbidity, while the same amount of alum had a minimal effect on turbidity. Extracts were prepared from the seeds in an attempt to separate the proteins. A crude protein extract was enriched by lowering the pH tomore » 6.0. Only 0.08 mg/L of the enriched extract was required to flocculate a minusil suspension. Environmentally friendly protein flocculants could theoretically be produced and enhanced with recombinant DNA techniques as an alternative to chemical flocculants currently used in water treatment.« less

Teacher in a problem-based learning environment - Jack of all trades?

NASA Astrophysics Data System (ADS)

Dahms, Mona Lisa; Spliid, Claus Monrad; Nielsen, Jens Frederik Dalsgaard

2017-11-01

Problem-based learning (PBL) is one among several approaches to active learning. Being a teacher in a PBL environment can, however, be a challenge because of the need to support students' learning within a broad 'landscape of learning'. In this article we will analyse the landscape of learning by use of the study activity model (SAM) developed by the Danish University Colleges, with the aim of investigating to which extent this may lead to explication and clarification concerning the challenges faced by teachers in a PBL environment. In the case study, the SAM is applied to the first semester of an engineering programme at Aalborg University, a university setting where the PBL approach to teaching and learning is dominant. The results of the analysis are presented and discussed, and the conclusion is that the model, in spite of some shortcomings, is useful in clarifying the role of the teacher in a PBL environment.

Scaman, Christine H; Jim, Vickie Jin Wai; Hartnett, Carol

2004-02-11

Gas chromatography was used to quantitate free galactose in Braeburn, Fuji, Red Delicious, and Spartan apples during cold storage, after thermal processing of apple slices and in juice produced using clarification and/or liquifaction enzymes. Spartan had significantly higher galactose levels as compared to Red Delicious apples, but changes in galactose in all varieties during 9 months of cold storage were insignificant. Blanching and canning decreased galactose levels, but doubling the thermal processing during canning increased the free galactose concentration detected in plant tissue. An enzymatic liquefaction aid used to prepare apple juice dramatically increased the free galactose content while a clarification aid caused only a slight increase due to its selective action on soluble pectin. These findings provide useful information for dietitians to base diet recommendations for galactosemic patients.

Clarification? Yes! Standarization? No. Or: What Kind of Cooperation for the Sociology of Culture?

PubMed

Krause, Monika

2016-01-01

Christian Smith's paper "The Incoherence of 'Culture' in American Sociology" is a valuable provocation that can prompt us to reflect on the role of concepts and on the role of agreement on the definition of concepts in scientific research. In this comment paper, I raise questions about Smith's empirical expectation that sociologists should agree on a concept of culture based on debates in the sociology of science. I also suggest that in terms of the future agenda for the sociology of culture, we should distinguish between dialogue and clarification on the one hand, which I agree is needed, and standardization on the other hand, which seems incompatible with open-minded empirical research. Rather than work on agreement on what culture is, we might work on clarifying relevant distinctions among dimensions of culture.

The effect of equipment proximity on safe performance in a manufacturing setting.

We examined the effect of equipment proximity on the safe performance of 3 assembly workers in a manufacturing setting. After a baseline period in which protective eyewear was kept 6.1 m from employee workstations, task clarification was used to inform participants to wear their eyewear while they worked. Next, the eyewear was moved to 1.5 m from employee workstations. After a return to the 6.1-m condition, the eyewear was again positioned 1.5 m from workstations. Results indicate that task clarification alone was ineffective, but safe performance increased when eyewear was stored in close proximity to employees. A social validity measure suggested that safe performance among the employees increased to levels comparable to that of an exemplary employee. © Society for the Experimental Analysis of Behavior.

2018-06-01

Wide range of CdO—Na2B4O7 glasses have been prepared and characterized via XRD, FTIR and UV spectroscopies along with DTA and ultrasonic techniques. The compositional dependence of the physical parameters such as the density, the molar volume, the optical transmittance, the optical band gap, the ultrasonic velocities and the elastic moduli on CdO content were determined. The profiles of XRD assured the amorphous nature of the explored glasses. The clarification of the borate and cadmium functional groups besides their linkages was extracted from the deconvoluted FTIR spectra. Such a clarification was used in the analysis of the relation of the mechanical, T g and optical parameters versus CdO content. These physical parameters revealed the glass modifier role of CdO.

The effect of electronic medical record system use on communication between pharmacists and prescribers.

PubMed

Singer, Alexander; Duarte Fernandez, Roberto

2015-10-28

The Electronic Medical Record (EMR) is becoming increasingly common in health care settings. Research shows that EMRs have the potential to reduce instances of medication errors and improve communication between pharmacists and prescribers; however, more research is required to demonstrate whether this is true. This study aims to determine the effect of a newly implemented EMR system on communication between pharmacists and primary care clinicians. A retrospective chart analysis of primary care EMR data comparing faxed pharmacy communications captured before and after the implementation of an EMR system at an academic family medicine clinic. Communication requests were classified into the following various categories: refill accepted, refill denied, clarification, incorrect dose, interaction, drug insurance/coverage application, new prescription request, supplies request, continued care information, duplicate fax substitution, opioid early release request, confirmation by phone call, and other. The number and percentage of clarification requests, interaction notifications, and incorrect dose notifications were lower after the implementation of the EMR system. The number and percentage of refills accepted and new prescription requests increased after the implementation of the EMR system. The implementation of an EMR in an academic family medicine clinic had a significant effect on the volume of communication between pharmacists and prescribers. The amount of clarification requests and incorrect dosing communications decreased after EMR implementation. This suggests that EMRs improve prescribing safety. The increased amount of refills accepted and new prescription requests post EMR implementation suggests that the EMR is capable of changing prescription patterns.

However, the 2 guidelines differ with regard to the recommended threshold of aortic root or ascending aortic dilatation that would justify surgical intervention in patients with bicuspid aortic valves. The ACC and AHA therefore convened a subcommittee representing members of the 2 guideline writing committees to review the evidence, reach consensus, and draft a statement of clarification for both guidelines. This statement of clarification uses the ACC/AHA revised structure for delineating the Class of Recommendation and Level of Evidence to provide recommendations that replace those contained in Section 9.2.2.1 of the thoracic aortic disease guideline and Section 5.1.3 of the valvular heart disease guideline.

Adverse childhood experiences: towards a clear conceptual meaning.

Kalmakis, Karen A; Chandler, Genevieve E

2014-07-01

To report an analysis of the concept of adverse childhood experiences. Adverse childhood experiences have been associated with negative physical and psychological health outcomes, but this phenomenon lacks the clear, consistent meaning necessary for use in nursing research, theory development and practice. Concept clarification. The literature search was not limited a priori by date and included publications with abstracts in English from PubMed, CINAHL, PsychINFO and Social Abstracts. The search retrieved 128 articles published from 1970-2013. The search term 'adverse childhood experiences' was used, with similar terms permitted. A snowball approach was used to expand the search to relevant literature. The articles were read and analysed following Norris's five steps for concept clarification to refine, elucidate and operationally define the concept and the context in which it occurred. Adverse childhood experiences were defined operationally as childhood events, varying in severity and often chronic, occurring in a child's family or social environment that cause harm or distress, thereby disrupting the child's physical or psychological health and development. This concept clarification should raise awareness and understanding of the diverse nature and shared characteristics of adverse childhood experiences that are believed to influence the health of individuals as they age. This clarified concept will help expand research on health consequences of adverse childhood experiences and interventions to improve health. We recommend promoting a model of primary care that pays attention to the social and familial influences on the health of individuals worldwide. © 2013 John Wiley & Sons Ltd.

An in-silico insight into the characteristics of β-propeller phytase.

Phytase is an enzyme that is found extensively in the plant kingdom and in some species of bacteria and fungi. This paper identifies and analyses the available full length sequences of β-propeller phytases (BPP). BPP was chosen due to its potential applicability in the field of aquaculture. The sequences were obtained from the Uniprot database and subject to various online bioinformatics tools to elucidate the physio-chemical characteristics, secondary structures and active site compositions of BPP. Protparam and SOPMA were used to analyse the physiochemical and secondary structure characteristics, while the Expasy online modelling tool and CASTp were used to model the 3-D structure and identify the active sites of the BPP sequences. The amino acid compositions of the four sequences were compared and composed in a graphical format to identify similarities and highlight the potentially important amino acids that form the active site of BPP. This study aims to analyse BPP and contribute to the clarification of the molecular mechanism involved in the enzyme activity of BPP and contribute in part to the possibility of constructing a synthetic version of BPP.

Fluorochemical Mass Flows in a Municipal Wastewater Treatment Facility

Fluorochemicals have widespread applications and are released into municipal wastewater treatment plants via domestic wastewater. A field study was conducted at a full-scale municipal wastewater treatment plant to determine the mass flows of selected fluorochemicals. Flow-proportional, 24-h samples of raw influent, primary effluent, trickling filter effluent, secondary effluent, and final effluent and grab samples of primary, thickened, activated, and anaerobically-digested sludge were collected over ten days and analyzed by liquid chromatography electrospray-ionization tandem mass spectrometry. Significant decreases in the mass flows of perfluorohexane sulfonate and perfluorodecanoate occurred during trickling filtration and primary clarification, while activated sludge treatment decreased the mass flow of perfluorohexanoate. Mass flows of the 6:2 fluorotelomer sulfonate and perfluorooctanoate were unchanged as a result of wastewater treatment, which indicates that conventional wastewater treatment is not effective for removal of these compounds. A net increase in the mass flows for perfluorooctane and perfluorodecane sulfonates occurred from trickling filtration and activated sludge treatment. Mass flows for perfluoroalkylsulfonamides and perfluorononanoate also increased during activated sludge treatment and are attributed to degradation of precursor molecules. PMID:17180988

Bioethics education for practicing nurses in Taiwan: Confucian-Western clash.

Yang, Wan-Ping; Chen, Ching-Huey; Chao, Co-Shi Chantal; Lai, Wei-Shu

2010-07-01

To understand the gaps between current bioethics education and the requirements of practicing nurses, a semistructured questionnaire was used to invite the directors of nursing departments at all 82 teaching hospitals in Taiwan to participate in this survey. The response rate was 64.6%. Through content analysis we obtained information about previous bioethical training, required themes and content, recommended teaching strategies, and difficulties with education and its application. The results suggest that Taiwanese nursing personnel need to be instilled with both self-cultivation of morality and mental cultivation to acquire nursing virtues and the right attitudes toward bioethical issues. Good communication skills to prevent damage to the harmonious relationships between patients, their families and medical team members, policies that support the provision of systematic formal knowledge of ethics, small group training, and clarification of values were also shown to be important in bioethics education.

Transcending breast cancer: making meaning from diagnosis and treatment.

This qualitative approach study describes the experience of self-transcendence in women newly diagnosed with breast cancer. Fourteen women participated from a larger sample of women in a support group project. Each woman was interviewed three times over an 8-month period. Audiotaped transcripts were analyzed using Colaizzi's phenomenological techniques. Loss of a personal perception of good health and fear of dying from cancer forced women to reach both inside and outside of themselves for support and information. Bonding with other women with breast cancer led to further expansion of self-boundaries that brought comfort, a desire to modify life priorities, and enhanced appreciation of supportive others and of life itself. Over time, clarification and modification of values and behaviors assisted women to create meaning from their experiences. Nurse referrals to support groups or other resources (such as cancer advocacy organizations) where women interact with similar others may facilitate transcending breast cancer.

Ultrafiltration of hemicellulose hydrolysate fermentation broth

NASA Astrophysics Data System (ADS)

Kresnowati, M. T. A. P.; Desiriani, Ria; Wenten, I. G.

2017-03-01

Hemicelulosic material is often used as the main substrate to obtain high-value products such as xylose. The five carbon sugar, xylose, could be further processed by fermentation to produce xylitol. However, not only the hemicellulose hydrolysate fermentation broth contains xylitol, but also metabolite products, residual substances, biomass and mineral salts. Therefore, in order to obtain the end products, various separation processes are required to separate and purify the desired product from the fermentation broth. One of the most promising downstream processing methods of fermentation broth clarification is ultrafiltration due to its potential for energy saving and higher purity. In addition, ultrafiltration membrane has a high performance in separating inhibitory components in the fermentation broth. This paper assesses the influence of operating conditions; including trans-membrane pressure, velocity, pH of the fermentation broth solutions, and also to the xylitol concentration in the product. The challenges of the ultrafiltration process will be pointed out.

Informed and shared decision making are critical aspects of patient-centered care, which has contributed to an emphasis on decision support interventions to promote good medical decision making. However, researchers and healthcare providers have not reached a consensus on what defines a good decision, nor how to evaluate it. This position paper, informed by conference sessions featuring diverse stakeholders held at the 2015 Society of Behavioral Medicine and Society for Medical Decision Making annual meetings, describes key concepts that influence the decision making process itself and that may change what it means to make a good decision: interpersonal factors, structural constraints, affective influences, and values clarification methods. This paper also proposes specific research questions within each of these priority areas, with the goal of moving medical decision making research to a more comprehensive definition of a good medical decision, and enhancing the ability to measure and improve the decision making process.

Cavitation erosion - scale effect and model investigations

NASA Astrophysics Data System (ADS)

Geiger, F.; Rutschmann, P.

2015-12-01

The experimental works presented in here contribute to the clarification of erosive effects of hydrodynamic cavitation. Comprehensive cavitation erosion test series were conducted for transient cloud cavitation in the shear layer of prismatic bodies. The erosion pattern and erosion rates were determined with a mineral based volume loss technique and with a metal based pit count system competitively. The results clarified the underlying scale effects and revealed a strong non-linear material dependency, which indicated significantly different damage processes for both material types. Furthermore, the size and dynamics of the cavitation clouds have been assessed by optical detection. The fluctuations of the cloud sizes showed a maximum value for those cavitation numbers related to maximum erosive aggressiveness. The finding suggests the suitability of a model approach which relates the erosion process to cavitation cloud dynamics. An enhanced experimental setup is projected to further clarify these issues.

Visualizing context through theory deconstruction: a content analysis of three bodies of evaluation theory literature.

PubMed

Vo, Anne T

2013-06-01

While the evaluation field collectively agrees that contextual factors bear on evaluation practice and related scholarly endeavors, the discipline does not yet have an explicit framework for understanding evaluation context. To address this gap in the knowledge base, this paper explores the ways in which evaluation context has been addressed in the practical-participatory, values-engaged, and emergent realist evaluation literatures. Five primary dimensions that constitute evaluation context were identified for this purpose: (1) stakeholder; (2) program; (3) organization; (4) historical/political; and (5) evaluator. Journal articles, book chapters, and conference papers rooted in the selected evaluation approaches were compared along these dimensions in order to explore points of convergence and divergence in the theories. Study results suggest that the selected prescriptive theories most clearly explicate stakeholder and evaluator contexts. Programmatic, organizational, and historical/political contexts, on the other hand, require further clarification. Copyright © 2012 Elsevier Ltd. All rights reserved.

This review covers the literature since the publication of DSM-IV on the diagnostic criteria for panic attacks (PAs) and panic disorder (PD). Specific recommendations are made based on the evidence available. In particular, slight changes are proposed for the wording of the diagnostic criteria for PAs to ease the differentiation between panic and surrounding anxiety; simplification and clarification of the operationalization of types of PAs (expected vs. unexpected) is proposed; and consideration is given to the value of PAs as a specifier for all DSM diagnoses and to the cultural validity of certain symptom profiles. In addition, slight changes are proposed for the wording of the diagnostic criteria to increase clarity and parsimony of the criteria. Finally, based on the available evidence, no changes are proposed with regard to the developmental expression of PAs or PD. This review presents a number of options and preliminary recommendations to be considered for DSM-V.

Team approach to treatment of the posttraumatic stiff hand. A case report.

PubMed

Morey, K R; Watson, A H

1986-02-01

Posttraumatic hand stiffness is a common but complex problem treated in many general clinics and in hand treatment centers. Although much information is available regarding various treatment procedures, the use of a team approach to evaluate and treat hand stiffness has not been examined thoroughly in the Journal. The problems of the patient with a stiff hand include both physical and psychological components that must be addressed in a structured manner. The clinical picture of posttraumatic hand stiffness involves edema, immobility, pain, and the inability to incorporate the affected extremity into daily activities. In this case report, we review the purpose and philosophy of the team approach to hand therapy and the clarification of responsibilities for physical therapy and occupational therapy intervention.

Gavshon, A

1995-01-01

This paper shows how environmental and medical overstimulation affected a latency girl in all her developmental phases, leading to severe impairment of object relationships. These factors are seen against the background of an acrimonious parental divorce. Suzie's negative body image was inextricably interwoven with anxieties about her masturbation activities and castration fantasies and this was fueled by her physical condition (lichen sclerosis et atrophicis). She was in a constant state either of withdrawness or excitement. The initial task of the treatment was to provide Suzie with a holding environment so that she could find alternative means of gratification and control in order to manage within a more organized secondary process mode. When her difficulties around excitation abated, she could begin to make analytic use of verbalization, clarification, and interpretations.

Exploring ward nurses' perceptions of continuing education in clinical settings.

PubMed

Govranos, Melissa; Newton, Jennifer M

2014-04-01

Health care systems demand that nurses are flexible skilful workers who maintain currency and competency in order to deliver safe effective patient centered care. Nurses must continually build best practice into their care and acquire lifelong learning. Often this learning is acquired within the work environment and is facilitated by the clinical nurse educator. Understanding clinical nurses' values and needs of continuing education is necessary to ensure appropriate education service delivery and thus enhance patient care. To explore clinical ward-based nurses' values and perceptions towards continuing education and what factors impact on continuing education in the ward. A case study approach was utilized. A major teaching hospital in Melbourne, Australia. A range of clinical nursing staff (n=23). Four focus groups and six semi-structured individual interviews were undertaken. Focus group interviews explored participants' values and perceptions on continuing education through a values clarification tool. Thematic analysis of interviews was undertaken to identify themes and cluster data. Three central themes: 'culture and attitudes', 'what is learning?' and 'being there-being seen', emerged reflecting staffs' values and perceptions of education and learning in the workplace. Multiple factors influence ward nurses' ability and motivation to incorporate lifelong learning into their practice. Despite variance in nurses' values and perceptions of CE in clinical environments, CE was perceived as important. Nurses yearned for changes to facilitate lifelong learning and cultivate a learning culture. Clinical nurse educators need to be cognizant of adult learners' characteristics such as values, beliefs, needs and potential barriers, to effectively facilitate support in a challenging and complex learning environment. Organizational support is essential so ward managers in conjunction with educational departments can promote and sustain continuing education, lifelong learning and a culture conducive to learning. © 2013.

Values clarification in a decision aid about fertility preservation: does it add to information provision?

PubMed Central

2014-01-01

Background We aimed to evaluate the effect of a decision aid (DA) with information only compared to a DA with values clarification exercise (VCE), and to study the role of personality and information seeking style in DA-use, decisional conflict (DC) and knowledge. Methods Two scenario-based experiments were conducted with two different groups of healthy female participants. Dependent measures were: DC, knowledge, and DA-use (time spent, pages viewed, VCE used). Respondents were randomized between a DA with information only (VCE-) and a DA with information plus a VCE(VCE+) (experiment 1), or between information only (VCE-), information plus VCE without referral to VCE(VCE+), and information plus a VCE with specific referral to the VCE, requesting participants to use the VCE(VCE++) (experiment 2). In experiment 2 we additionally measured personality (neuroticism/conscientiousness) and information seeking style (monitoring/blunting). Results Experiment 1. There were no differences in DC, knowledge or DA-use between VCE- (n=70) and VCE+ (n=70). Both DAs lead to a mean gain in knowledge from 39% at baseline to 73% after viewing the DA. Within VCE+, VCE-users (n=32, 46%) reported less DC compared to non-users. Since there was no difference in DC between VCE- and VCE+, this is likely an effect of VCE-use in a self-selected group, and not of the VCE per se. Experiment 2. There were no differences in DC or knowledge between VCE- (n=65), VCE+ (n=66), VCE++ (n=66). In all groups, knowledge increased on average from 42% at baseline to 72% after viewing the DA. Blunters viewed fewer DA-pages (R=0.38, p<.001). More neurotic women were less certain (R=0.18, p<.01) and felt less supported in decision making (R=0.15, p<.05); conscientious women felt more certain (R=-0.15, p<.05) and had more knowledge after viewing the DA (R=0.15, p<.05). Conclusions Both DAs lead to increased knowledge in healthy populations making hypothetical decisions, and use of the VCE did not improve knowledge or DC. Personality characteristics were associated to some extent with DA-use, information seeking styles with aspects of DC. More research is needed to make clear recommendations regarding the need for tailoring of information provision to personality characteristics, and to assess the effect of VCE use in actual patients.

Brief communication: Enamel thickness and durophagy in mangabeys revisited.

PubMed

McGraw, W Scott; Pampush, James D; Daegling, David J

2012-02-01

The documentation of enamel thickness variation across primates is important because enamel thickness has both taxonomic and functional relevance. The Old World monkeys commonly referred to as mangabeys have figured prominently in investigations of feeding ecology and enamel thickness. In this article, we report enamel thickness values for four mangabey taxa (Cercocebus atys, Cercocebus torquatus, Lophocebus aterrimus, and Lophocebus albigena), offer revised interpretation of the significance of thick enamel in papionin evolution, and place our new data in a broader comparative framework. Our data indicate that all mangabeys have thick enamel and that the values obtained for Cercocebus and Lophocebus equal or exceed those published for most extant non-human primates. In addition, new field data combined with a current reading of the dietary literature indicate that hard foods make up a portion of the diet of every mangabey species sampled to date. Clarification on the relationship between diet and enamel thickness among mangabeys is important not only because of recognition that mangabeys are not a natural group but also because of recent arguments that explain thick enamel as an evolved response to the seasonal consumption of hard foods.

This study was designed to survey and compare attitudes and perceptions toward school counseling and student personnel programs as held by educators in the Caribbean. The subjects in the study comprised 275 teachers and administrators employed in public and private junior and senior high schools in Nassau, Bahamas. The statistical tests used to analyze the data were the Kruskal-Wallis one-way analysis of variance and the Friedman two-way analysis for repeated measures. The findings indicate that administrators at all levels expressed significantly more favorable attitudes and perceptions toward counseling and student personnel programs in the schools than teachers. Teachers in the study expressed the following: (a) serious concern regarding the competency of practicing counselors in their schools; (b) a need for clarification of their role and function in the guidance process and a clarification of the counselor's role; and (c) minimum acceptable standards should be established for school counseling positions.

To develop and test an educational programme on quality and safety in medication handling for staff in residential facilities for the disabled. The continuing pharmacy education instructional design model was used to develop the programme with 22 learning objectives on disease and medicines, quality and safety, communication and coordination. The programme was a flexible, modular seven + two days' course addressing quality and safety in medication handling, disease and medicines, and medication supervision and reconciliation. The programme was tested in five Danish municipalities. Municipalities were selected based on their application for participation; each independently selected a facility for residents with mental and intellectual disabilities, and a facility for residents with severe mental illnesses. Perceived effects were measured based on a questionnaire completed by participants before and after the programme. Effects on motivation and confidence as well as perceived effects on knowledge, skills and competences related to medication handling, patient empowerment, communication, role clarification and safety culture were analysed conducting bivariate, stratified analyses and test for independence. Of the 114 participants completing the programme, 75 participants returned both questionnaires (response rate = 66%). Motivation and confidence regarding quality and safety in medication handling significantly improved, as did perceived knowledge, skills and competences on 20 learning objectives on role clarification, safety culture, medication handling, patient empowerment and communication. The programme improved staffs' motivation and confidence and their perceived ability to handle residents' medication safely through improved role clarification, safety culture, medication handling and patient empowerment and communication skills. © 2017 Royal Pharmaceutical Society.

Facilitating pragmatic skills through role-play in learners with language learning disability.

PubMed

Abdoola, Fareeaa; Flack, Penelope S; Karrim, Saira B

2017-07-26

Role-based learning involves the process whereby learners acquire skills, knowledge and understanding through the assumption of roles within real-life settings. Role-play holds potential as an effective learning strategy for children; however, there is limited research on the use of role-play as a therapy method within the field of speech-language pathology. Children with language learning disability (LLD) typically present with difficulties in social communication, which can negatively affect their social and academic achievement. The aim of this study was to determine the effectiveness of role-play as a therapy approach targeting the pragmatic skills of stylistic variation and requesting for clarification in learners with LLD. The use of combined positivist and interpretivist paradigms allowed for the implementation of an embedded mixed methods design. An experimental pretest-posttest design was implemented. Eight participants, who were learners with a diagnosis of LLD, were purposefully selected. Data collection was conducted over five phases, utilising the Clinical Evaluation of Language Fundamentals (4th Ed.) Pragmatics Profile, discourse completion tasks, session plans and session records. Quantitative data were analysed using descriptive statistics and were supplemented by qualitative data from session records. Results revealed improvements in stylistic variation and requesting for clarification post role-play intervention, with minimal changes in the control group. Limitations of the study have been reported for consideration when interpreting results. Role-play as a therapy approach targeting two pragmatic skills, stylistic variation and requesting for clarification, was found to be beneficial for learners with LLD. Recommendations for the implementation of role-play as a therapy approach were made.

Letter to the editor: Critical assessments of the current state of scientific knowledge, terminology, and research needs concerning the ecological effects of elevated atmospheric nitrogen deposition in China

In a publication in Atmospheric Environment (http://dx.doi.org/10.1016/j.atmosenv.2015.10.081), Gu et al. (2015) estimated that "the total nitrogen (N) deposition in 2010 was 2.32 g N m-2 yr-1" in China. This value is comparable with previous estimations based on a synthesized dataset of wet/bulk inorganic N deposition observations, which underestimates the total N deposition since their algorithm (equations (2) and (3) in their paper) does not account for dry deposition of NH3, HNO3, NOx and wet/dry deposition of HONO and organic nitrogen (e.g. amines, amides, PAN). Indeed, Gu et al. (2015) mixed the terminology of wet/bulk deposition and total deposition. Another flawed assumption by Gu et al. (2015) is that all inorganic N in precipitation estimated by their algorithm originates from fertilizer and coal combustion. This is incorrect and almost certainly causes biases in the spatial and temporal distribution of estimated wet/bulk inorganic N deposition (Fig. 5 in their paper), further considering the fact that they neglected important N sources like livestock and they did not consider the nonlinearity between various sources and deposition. Besides the input data on N deposition, the model validation (Sect. 2.3.2) described in their paper also requires clarification because the detailed validation information about the time series of observational dataset versus modeling results was not given. As a result of these combined uncertainties in their estimation of N deposition and the lack of detail for model-measurement comparison, their estimates of the impacts of N deposition on carbon storage in Chinese forests may need further improvement. We suggest the clarification of the terminology regarding N deposition, especially for wet deposition, bulk deposition, gaseous and particulate dry deposition or total deposition since the accurate distinction between these terms is crucial to investigating and estimating the effects of N deposition on ecosystems.

Does serotonin-modulating anticonsolidation protein (SMAP) influence the choice of turning direction in carps, Cyprinus carpio, in a T-maze?

Garina, D V; Nepomnyashchikh, V A; Mekhtiev, A A

Serotonin-modulating anticonsolidation protein (SMAP) can impair the formation of memory traces in mammals and fish. We have studied the influence of SMAP on behavioral lateralization of juvenile carps Cyprinus carpio in a T-maze without food reinforcement in three experimental groups (n = 8 each): (1) negative control (intact animals); (2) experimental group (fish injected ICV with SMAP; 2 μl, 1.2 mg ml(-1)) and (3) active control group (fish injected ICV with inactivated SMAP). The behavioral lateralization of carps was observed on the 1st, 2nd, 3rd and 6th days after the injections. In each observation session, a fish was placed five times in a start chamber of the T-maze. The direction of the turn upon leaving the start chamber, as well as the latency from the opening of start chamber flap to the fish's turn was registered. The number of right turns (of all five turns observed during the session) was a criterion of lateralization. It was found that carps have no inherent preference for turning left or right. The SMAP injection did not influence the choice of turning direction, but increases latency values insignificantly. The results are important for the correct interpretation and clarification of data reporting the role of SMAP in training and formation of spatial memory of fish in a maze.

Abstract Objective  Treatment decisions in advanced breast cancer are complex, with enhanced quality of life and survival among important treatment goals. Patients with metastatic breast cancer face the decision of whether or not to have chemotherapy, and many wish to be involved in this decision. We report the development and evaluation of a decision aid (DA) designed to assist patients facing this treatment decision. Design and sample  Women with metastatic breast cancer (n = 17) and medical oncologists in Australia and Canada (n = 7) were invited to evaluate the DA. Intervention  A DA was developed for patients with hormone‐resistant metastatic breast cancer considering chemotherapy. The DA presented options of supportive care, with or without chemotherapy. Potential benefits and side effects of different chemotherapy regimens, and evidence‐based prognostic estimates were described, and a values clarification exercise included. Main outcome measures  Patient questionnaires evaluating information and decision involvement preferences, attitudes toward the DA and oncologist feedback regarding attitudes toward the DA. Results  Seventeen patients participated; fifteen desired as much information about their illness as possible; sixteen wished to be actively involved in the decision‐making process. The majority rated the DA as highly acceptable, clear and informative, and would recommend it to others facing this treatment decision. Conclusion  This is the first DA for patients with advanced metastatic breast cancer considering chemotherapy. A randomized trial is underway to evaluate its role in clinical decision‐making.

Policy initiatives and an increasing amount of the literature within higher education both call for students to become more involved in creating their own learning. However, there is a lack of studies in undergraduate nursing education that actively involve students in developing such learning material with descriptions of the students' roles in these interactive processes. Explorative qualitative study, using data from focus group interviews, field notes and student notes. The data has been subjected to qualitative content analysis. Active student involvement through an iterative process identified five different learning needs that are especially important to the students: clarification of learning expectations, help to recognize the bigger picture, stimulation of interaction, creation of structure, and receiving context- specific content. The iterative process involvement of students during the development of new technological learning material will enhance the identification of important learning needs for students. The use of student and teacher knowledge through an adapted co-design process is the most optimal level of that involvement.

[Synthesis and properties of immobilized enzymes. X. Covalent binding of polygalacturonase to insoluble carriers].

1978-01-01

The pectinolytic enzymes are of practical interest for the clarification of fruit juice. In the present paper the covalent coupling of polygalacturonase (PG; E. C. 3.2.1.15) is reported. A commercially available enzyme (Rohament P; 5 U/mg) and purified Endo-PG (200 U/mg) are immobilized to the following carriers: BrCN-activated Sepharose, carbodiimide-activated CH-Sepharose, dialdehyde Sepharose, dialdehyde Sephadex, dialdehyde cellulose, CMC-azide, carbodiimide-activated CMC, macroporous glass (isothiocyanate and carbodiimide coupling) and glass beads. The implications of pore diameter (Sephadex- and Sepharose derivatives), of purity of the PG, of protein content of the PG-carrier-complexes as well as the presence of substrate during the coupling reaction, are discused in relation to the relative and specific activity of the bound protein and to the efficiency of the coupling reaction. From the carriers under study derivatives of Sepharose yield the best result (relative activity max. 88%, specific activity max. 5400 U/mg). The immobilization to isothiocyanate glass yields good results, too (relative activity 20%, specific activity 500 U/g). The mechanical instability of the PG-dialdehye Sephadex-complexes and the low relative activity of the bound enzyme are unsatisfactory. Due to their low affinity to PG, the derivatives of cellulose are also inappropriate for covalent coupling of this enzyme. All PG-carrier-complexes are largely stable both during storage at 4 degrees C and repeated activity assays.

Contribution of Microglia-Mediated Neuroinflammation to Retinal Degenerative Diseases

PubMed Central

Madeira, Maria H.; Boia, Raquel; Santos, Paulo F.; Ambrósio, António F.; Santiago, Ana R.

2015-01-01

Retinal degenerative diseases are major causes of vision loss and blindness worldwide and are characterized by chronic and progressive neuronal loss. One common feature of retinal degenerative diseases and brain neurodegenerative diseases is chronic neuroinflammation. There is growing evidence that retinal microglia, as in the brain, become activated in the course of retinal degenerative diseases, having a pivotal role in the initiation and propagation of the neurodegenerative process. A better understanding of the events elicited and mediated by retinal microglia will contribute to the clarification of disease etiology and might open new avenues for potential therapeutic interventions. This review aims at giving an overview of the roles of microglia-mediated neuroinflammation in major retinal degenerative diseases like glaucoma, age-related macular degeneration, and diabetic retinopathy.

The vexing problem of defining the meaning, role and measurement of values in treatment decision-making.

PubMed

Charles, Cathy; Gafni, Amiram

2014-03-01

Two international movements, evidence-based medicine (EBM) and shared decision-making (SDM) have grappled for some time with issues related to defining the meaning, role and measurement of values/preferences in their respective models of treatment decision-making. In this article, we identify and describe unresolved problems in the way that each movement addresses these issues. The starting point for this discussion is that at least two essential ingredients are needed for treatment decision-making: research information about treatment options and their potential benefits and risks; and the values/preferences of participants in the decision-making process. Both the EBM and SDM movements have encountered difficulties in defining the meaning, role and measurement of values/preferences in treatment decision-making. In the EBM model of practice, there is no clear and consistent definition of patient values/preferences and no guidance is provided on how to integrate these into an EBM model of practice. Methods advocated to measure patient values are also problematic. Within the SDM movement, patient values/preferences tend to be defined and measured in a restrictive and reductionist way as patient preferences for treatment options or attributes of options, while broader underlying value structures are ignored. In both models of practice, the meaning and expected role of physician values in decision-making are unclear. Values clarification exercises embedded in patient decision aids are suggested by SDM advocates to identify and communicate patient values/preferences for different treatment outcomes. Such exercises have the potential to impose a particular decision-making theory and/or process onto patients, which can change the way they think about and process information, potentially impeding them from making decisions that are consistent with their true values. The tasks of clarifying the meaning, role and measurement of values/preferences in treatment decision-making models such as EBM and SDM, and determining whose values ought to count are complex and difficult tasks that will not be resolved quickly. Additional conceptual thinking and research are needed to explore and clarify these issues. To date, the values component of these models remains elusive and underdeveloped.

Patterns of productive activity engagement as a longitudinal predictor of depressive symptoms among older adults in urban China.

PubMed

Liu, Huiying; Lou, Vivian W Q

2017-11-01

Using two waves of panel data from the China Health and Retirement Longitudinal Study, this study prospectively assessed whether four distinct patterns of productive activity engagement would predict depressive symptoms among older adults in urban China two years later. A sample of urban residents aged 60 or above at Wave 1 and who were interviewed in both waves (N = 2398) was used. Latent class analysis (LCA) was conducted to identify distinct patterns of productive activity engagement that occurred within the Wave 1 data. Next, the generalized estimating equations were used to assess whether identified patterns predicted the levels of depressive symptoms measured at Wave 2. Our use of LCA confirmed the existence of four distinct patterns of productive activity engagement among the study sample: Informal Helper/Carer, Working-Caring Engager, Civic Contributor, and Low/Spousal Carer. All of these three patterns exhibited significantly lower levels of depressive symptoms than that of Low/Spousal Carer two years later. Our use of individual-based categorization of productive engagement better captured the reality of older adults performing various productive activities than summative scales of productive activities did and, therefore, provided a more valid clarification of differential well-being outcomes among older adults.

Virtual patient care: an interprofessional education approach for physician assistant, physical therapy and occupational therapy students.

Shoemaker, Michael J; Platko, Christina M; Cleghorn, Susan M; Booth, Andrew

2014-07-01

The purpose of this retrospective qualitative case report is to describe how a case-based, virtual patient interprofessional education (IPE) simulation activity was utilized to achieve physician assistant (PA), physical therapy (PT) and occupational therapy (OT) student IPE learning outcomes. Following completion of a virtual patient case, 30 PA, 46 PT and 24 OT students were required to develop a comprehensive, written treatment plan and respond to reflective questions. A qualitative analysis of the submitted written assignment was used to determine whether IPE learning objectives were met. Student responses revealed three themes that supported the learning objectives of the IPE experience: benefits of collaborative care, role clarification and relevance of the IPE experience for future practice. A case-based, IPE simulation activity for physician assistant and rehabilitation students using a computerized virtual patient software program effectively facilitated achievement of the IPE learning objectives, including development of greater student awareness of other professions and ways in which collaborative patient care can be provided.

Complement-mediated neutrophil activation in sepsis- and trauma-related adult respiratory distress syndrome. Clarification with radioaerosol lung scans

DOE Office of Scientific and Technical Information (OSTI.GOV)

Tennenberg, S.D.; Jacobs, M.P.; Solomkin, J.S.

Complement-mediated neutrophil activation (CMNA) has been proposed as an important pathogenic mechanism causing acute microvascular lung injury in the adult respiratory distress syndrome (ARDS). To clarify the relationship between CMNA and evolving lung injury, we studied 26 patients with multiple trauma and sepsis within 24 hours of risk establishment for ARDS. Pulmonary alveolar-capillary permeability (PACP) was quantified as the clearance rate of a particulate radioaerosol. Seventeen patients (65%) had increased PACP (six developed ARDS) while nine (35%) had normal PACP (none developed ARDS; clearance rates of 3.4%/min and 1.5%/min, respectively). These patients, regardless of evidence of early lung injury, hadmore » elevated plasma C3adesArg levels and neutrophil chemotactic desensitization to C5a/C5adesArg. Plasma C3adesArg levels correlated weakly, but significantly, with PACP. Thus, CMNA may be a necessary, but not a sufficient, pathogenic mechanism in the evolution of ARDS.« less

Intrinsic movement variability at work. How long is the path from motor control to design engineering?

PubMed

Gaudez, C; Gilles, M A; Savin, J

2016-03-01

For several years, increasing numbers of studies have highlighted the existence of movement variability. Before that, it was neglected in movement analysis and it is still almost completely ignored in workstation design. This article reviews motor control theories and factors influencing movement execution, and indicates how intrinsic movement variability is part of task completion. These background clarifications should help ergonomists and workstation designers to gain a better understanding of these concepts, which can then be used to improve design tools. We also question which techniques--kinematics, kinetics or muscular activity--and descriptors are most appropriate for describing intrinsic movement variability and for integration into design tools. By this way, simulations generated by designers for workstation design should be closer to the real movements performed by workers. This review emphasises the complexity of identifying, describing and processing intrinsic movement variability in occupational activities. Copyright © 2015 Elsevier Ltd and The Ergonomics Society.

2010-01-01

Capture, coding and communication of newborn screening (NBS) information represent a challenge for public health laboratories, health departments, hospitals, and ambulatory care practices. An increasing number of conditions targeted for screening and the complexity of interpretation contribute to a growing need for integrated information-management strategies. This makes NBS an important test of tools and architecture for electronic health information exchange (HIE) in this convergence of individual patient care and population health activities. For this reason, the American Health Information Community undertook three tasks described in this paper. First, a newborn screening use case was established to facilitate standards harmonization for common terminology and interoperability specifications guiding HIE. Second, newborn screening coding and terminology were developed for integration into electronic HIE activities. Finally, clarification of privacy, security, and clinical laboratory regulatory requirements governing information exchange was provided, serving as a framework to establish pathways for improving screening program timeliness, effectiveness, and efficiency of quality patient care services.

2016-01-01

The nature of the alteration of the response to cognitive tasks in first-episode psychosis (FEP) still awaits clarification. We used activation likelihood estimation, an increasingly used method in evaluating normal and pathological brain function, to identify activation changes in functional magnetic resonance imaging (fMRI) studies of FEP during attentional and memory tasks. We included 11 peer-reviewed fMRI studies assessing FEP patients versus healthy controls (HCs) during performance of attentional and memory tasks. Our database comprised 290 patients with FEP, matched with 316 HCs. Between-group analyses showed that HCs, compared to FEP patients, exhibited hyperactivation of the right middle frontal gyrus (Brodmann area, BA, 9), right inferior parietal lobule (BA 40), and right insula (BA 13) during attentional task performances and hyperactivation of the left insula (BA 13) during memory task performances. Right frontal, parietal, and insular dysfunction during attentional task performance and left insular dysfunction during memory task performance are significant neural functional FEP correlates. © 2016 S.

Esawy, Mona A; Gamal, Amira A; Kamel, Zeinat; Ismail, Abdel-Mohsen S; Abdel-Fattah, Ahmed F

2013-02-15

The Aspergillus niger NRC1ami pectinase was evaluated according to its hydrolysis efficiency of dry untreated orange peels (UOP), HCl-treated orange peels and NaOH-treated orange peels (HOP and NOP). Pectinase was entrapped in polyvinyl alcohol (PVA) sponge and the optimum pH and temperature of the free and immobilized enzymes were shifted from 4, 40 °C to 6, 50 °C respectively. The study of pH stability of free and immobilized pectinase showed that the immobilization process protected the enzyme strongly from severe alkaline pHs. The immobilization process improved the enzyme thermal stability to great instant. The unique feature of the immobilization process is its ability to solve the orange juice haze problem completely. Immobilized enzyme was reused 12 times in orange juice clarification with 9% activity loss from the original activity. Maximum reaction rate (V(max)) and Michaelis-Menten constant (K(m)) of the partially purified form were significantly changed after immobilization. Copyright © 2012 Elsevier Ltd.

Vacancy-mediated dehydrogenation of sodium alanate

Gunaydin, Hakan; Houk, Kendall N.; Ozoliņš, Vidvuds

2008-01-01

Clarification of the mechanisms of hydrogen release and uptake in transition-metal-doped sodium alanate, NaAlH4, a prototypical high-density complex hydride, has fundamental importance for the development of improved hydrogen-storage materials. In this and most other modern hydrogen-storage materials, H2 release and uptake are accompanied by long-range diffusion of metal species. Using first-principles density-functional theory calculations, we have determined that the activation energy for Al mass transport via AlH3 vacancies is Q = 85 kJ/mol·H2, which is in excellent agreement with experimentally measured activation energies in Ti-catalyzed NaAlH4. The activation energy for an alternate decomposition mechanism via NaH vacancies is found to be significantly higher: Q = 112 kJ/mol·H2. Our results suggest that bulk diffusion of Al species is the rate-limiting step in the dehydrogenation of Ti-doped samples of NaAlH4 and that the much higher activation energies measured for uncatalyzed samples are controlled by other processes, such as breaking up of AlH4− complexes, formation/dissociation of H2 molecules, and/or nucleation of the product phases.

Ultra Scale-Down Characterization of the Impact of Conditioning Methods for Harvested Cell Broths on Clarification by Continuous Centrifugation—Recovery of Domain Antibodies from rec E. coli

PubMed Central

Chatel, Alex; Kumpalume, Peter; Hoare, Mike

2014-01-01

The processing of harvested E. coli cell broths is examined where the expressed protein product has been released into the extracellular space. Pre-treatment methods such as freeze–thaw, flocculation, and homogenization are studied. The resultant suspensions are characterized in terms of the particle size distribution, sensitivity to shear stress, rheology and solids volume fraction, and, using ultra scale-down methods, the predicted ability to clarify the material using industrial scale continuous flow centrifugation. A key finding was the potential of flocculation methods both to aid the recovery of the particles and to cause the selective precipitation of soluble contaminants. While the flocculated material is severely affected by process shear stress, the impact on the very fine end of the size distribution is relatively minor and hence the predicted performance was only diminished to a small extent, for example, from 99.9% to 99.7% clarification compared with 95% for autolysate and 65% for homogenate at equivalent centrifugation conditions. The lumped properties as represented by ultra scale-down centrifugation results were correlated with the basic properties affecting sedimentation including particle size distribution, suspension viscosity, and solids volume fraction. Grade efficiency relationships were used to allow for the particle and flow dynamics affecting capture in the centrifuge. The size distribution below a critical diameter dependant on the broth pre-treatment type was shown to be the main determining factor affecting the clarification achieved. Biotechnol.

Facilitating pragmatic skills through role-play in learners with language learning disability

Flack, Penelope S.

2017-01-01

Background Role-based learning involves the process whereby learners acquire skills, knowledge and understanding through the assumption of roles within real-life settings. Role-play holds potential as an effective learning strategy for children; however, there is limited research on the use of role-play as a therapy method within the field of speech-language pathology. Children with language learning disability (LLD) typically present with difficulties in social communication, which can negatively affect their social and academic achievement. Aim The aim of this study was to determine the effectiveness of role-play as a therapy approach targeting the pragmatic skills of stylistic variation and requesting for clarification in learners with LLD. Method The use of combined positivist and interpretivist paradigms allowed for the implementation of an embedded mixed methods design. An experimental pretest-posttest design was implemented. Eight participants, who were learners with a diagnosis of LLD, were purposefully selected. Data collection was conducted over five phases, utilising the Clinical Evaluation of Language Fundamentals (4th Ed.) Pragmatics Profile, discourse completion tasks, session plans and session records. Quantitative data were analysed using descriptive statistics and were supplemented by qualitative data from session records. Results Results revealed improvements in stylistic variation and requesting for clarification post role-play intervention, with minimal changes in the control group. Limitations of the study have been reported for consideration when interpreting results. Conclusion Role-play as a therapy approach targeting two pragmatic skills, stylistic variation and requesting for clarification, was found to be beneficial for learners with LLD. Recommendations for the implementation of role-play as a therapy approach were made. PMID:28828866
