We agree that institutions and rules are crucial for explaining human sociality, but we question the claim of there not being "alternatives to CGS [that] can easily account for the institutionalized cooperation that characterizes human societies" (target article, sect. 7). Hypothesizing that self-interested individuals coercively and collaboratively create rules, we propose that agent-based hypotheses offer viable alternatives to cultural group selection (CGS).

Maintaining consistency in distributed systems

Birman, Kenneth P.

1991-01-01

In systems designed as assemblies of independently developed components, concurrent access to data or data structures normally arises within individual programs, and is controlled using mutual exclusion constructs, such as semaphores and monitors. Where data is persistent and/or sets of operation are related to one another, transactions or linearizability may be more appropriate. Systems that incorporate cooperative styles of distributed execution often replicate or distribute data within groups of components. In these cases, group oriented consistency properties must be maintained, and tools based on the virtual synchrony execution model greatly simplify the task confronting an application developer. All three styles of distributed computing are likely to be seen in future systems - often, within the same application. This leads us to propose an integrated approach that permits applications that use virtual synchrony with concurrent objects that respect a linearizability constraint, and vice versa. Transactional subsystems are treated as a special case of linearizability.

Full Text Available Tracheobronchial secretion was collected by endoscopy (Welch-AllynÒ, 200cm long and 9mm diameter, from equines with different ages, races and sex, for posterior cytological analysis. Thirty-six equines were divided into two groups (Group I = stabled, n = 18; Group II = field regimen, n = 18. Animals of Group I (age = 3.5 years were lodged in the Tarumã´s Jockey Club in Curitiba, Parana State. The equines of Group II always were maintained at field condition (never were stabled, in the farm located in Jacarezinho, Paraná State. Following endoscopic exams, tracheobronchial secretion smears were stained by Pappenhein´s method and submitted to cytological analysis. Group I had higher frequency of tracheal discharge than Group II. The cytological analysis showed more presence of macrophages (58.8%, foamy cells (2.3%, body giant cells (0.2%, neutrophils (4.57%, eosinophils (0.7% and Curshmann´s spirals (0.04% on 3 of the 18 animals. The cytological analysis of Group II showed higher frequency of ciliated epithelial cells than Group I, and no Curshmann´s spirals were observed. In conclusion, data showed that horses stabled had more cytological alterations than the animals maintained at field, therefore more tracheobronchial complications. Thus, the care of place where horse are stabled have influence on development of respiratory diseases, may predispose to affections as Chronic Obstructive Pulmonary Disease and Exercise-Induced Pulmonary Hemorrhage, as well athletic horses may be never reach their full respiratory potential.

Peer support can be helpful in rehabilitation from breast cancer, but participation in peer support groups is low. Groups that provide support opportunities in physical activity contexts are an attractive alternative for some survivors. This study examined survivors' reasons for joining and maintaining participation on a dragon boat team, along with perceptions of barriers and attractions to traditional peer support groups. Seventeen breast cancer survivors were interviewed on five occasions over their first two seasons of a newly formed dragon boating team to explore their perceptions of peer support groups and dragon boating. Data were inductively analyzed using thematic analysis. Categories surrounding physical, psychological, social and community features were identified with several themes emerging within each. Advantages of dragon boating included opportunities to get a combination of physical, psychosocial and community benefits; health improvement and behavior change; and obtaining social support without the focus being on cancer. Peer support groups were identified as having advantages for forming relationships and avoiding barriers associated with physical activity. While neither type of program meets all needs, practical considerations are identified for incorporating advantages of both programs to improve participation. Implications for rehabilitation Further understanding of perceptions, and attractions and challenges to taking part in group programs will inform development of accessible programs that target multiple rehabilitation needs. Physical activity can provide a positive, alternative focus that takes the emphasis off of cancer, which is more accessible to some survivors. Physical activity also provides opportunities to build relationships around a common, positive goal, which can be a foundation for providing support for coping with cancer.

With no evidence to guide management of the gastric band in pregnancy, we aim to compare outcomes according to band management. Data were collected on all women pregnant (November 2011-October 2012) following gastric banding, using the UK Obstetric Surveillance System surveillance system. We compared outcomes between band management groups and with national data. Band management was variable; deflation 43.4%, inflation maintained 56.6%. The deflation group had lower risk of small for gestational age infants (no cases vs. 11.3%; risk ratio = 0.14, p  = 0.05). There was greater gestational weight gain (deflation 15.4 kg, inflation 7.6 kg; adjusted p  = 0.05), and perhaps higher risk of gestational hypertension (deflation 10.5%, inflation no cases; p  = 0.08) in the deflation group. Other maternal outcomes were similar between management groups but overall worse than national data. Deflation is associated with better outcomes for babies but worse outcomes for mothers than maintained inflation.

Metabolic and hemodynamic effects of saline infusion to maintain volemia on temporary abdominal aortic occlusion

Full Text Available OBJECTIVE: To analyze hemodynamic and metabolic effects of saline solution infusion in the maintenance of blood volume in ischemia-reperfusion syndrome during temporary abdominal aortic occlusion in dogs. METHODS: We studied 20 dogs divided into 2 groups: the ischemia-reperfusion group (IRG, n=10 and the ischemia-reperfusion group with saline solution infusion aiming at maintaining mean pulmonary arterial wedge pressure between 10 and 20 mmHg (IRG-SS, n=10. All animals were anesthetized with sodium thiopental and maintained on spontaneous ventilation. Occlusion of the supraceliac aorta was obtained with inflation of a Fogarty catheter inserted through the femoral artery. After 60 minutes of ischemia, the balloon was deflated, and the animals were observed for another 60 minutes of reperfusion. RESULTS: IRG-SS dogs did not have hemodynamic instability after aortic unclamping, and the mean systemic blood pressure and heart rate were maintained. However, acidosis worsened, which was documented by a greater reduction of arterial pH that occurred especially due to the absence of a respiratory response to metabolic acidosis that was greater with the adoption of this procedure. CONCLUSION: Saline solution infusion to maintain blood volume avoided hemodynamic instability after aortic unclamping. This procedure, however, caused worsening in metabolic acidosis in this experimental model.

The SP group at the University of Copenhagen has for several years used a broad approach to SP teaching and research, often illustrated by the four levels: individual, group, organizational, and societal. In this paper the relevance of maintaining a broad approach to SP research is argued for and examples of the importance of such type of research is presented.

Constructability and maintainability

International Nuclear Information System (INIS)

Hart, R.S.

1985-01-01

A set of principles for minimizing the construction schedule was established at the outset of the CANDU 300 programme. Consideration of these principles and other factors led to the development of the unique CANDU 300 station layout. The paper discusses the CANDU 300 station layout and construction methods. In summary, the station layout provides 360 deg. construction access to all buildings, separation of nuclear and non-nuclear systems, precise and minimal physical interfaces between buildings, accommodation of many contractors and construction activities without interference, and maximum flexibility in terms of constructional, financial and supply arrangements. The CANDU 300 further employs modularization, shop fabrication and advanced instrumentation (multiplexers, remote processors, data highways) to minimize construction time. Many of the CANDU 300 features that enhance constructability also contribute to maintainability. These include the 360 deg. access to all principal buildings, the uncluttered and spacious building layouts, the simplification of systems and the high level of modularization. The CANDU 300 has also been designed to facilitate the replacement of all key components, thereby offering an essentially unlimited station life. A prime example is a reduction in the fuel channel inlet end-fitting diameter such that the fuel channels can be shop assembled and easily replaced after the initial 40 years of operation, without an extended unit outage. Maintainability within the reactor building has been given particular attention in the CANDU 300 design; key features of other CANDU reactors (the ability to replace a heat transport system pump motor at power, for example) have been incorporated, while accessibility and maintainability of all systems and components have been enhanced. These and other aspects of maintainability are discussed. (author)

Epoetin beta pegol is a continuous erythropoietin receptor activator (CERA) with a long half-life. Although CERA has been shown to maintain adequate hemoglobin (Hb) levels at prolonged dosing intervals, the optimal dosing schedule remains unclear. We therefore compared the efficacy of maintaining hemoglobin levels with administration of twice-monthly CERA (TWICE) versus once-monthly CERA (ONCE). Twenty hemodialysis patients receiving epoetin beta (EPO) were enrolled in this crossover study. Patients were assigned to either the TWICE or the ONCE group based on matching Hb levels and EPO doses. After 6 months of treatment, the CERA dosage was interchanged between the groups and the study was continued for an additional 6 months. The effect of the different regimens on iron metabolism was also assessed during the first 6 months of the study. Hb levels significantly increased in the TWICE group, allowing for a reduction in CERA dosage, while the dose of CERA required to maintain Hb levels in the ONCE group remained unchanged. After the interchange, a decrease in Hb levels with incremental increase in CERA dosage was observed in the TWICE→ONCE group, with the opposite effect observed in the ONCE→TWICE group. Although increases in ferritin and hepcidin-25 levels in the ONCE group were noted at one month, they disappeared at 6 months. Although Hb levels were maintained in both the ONCE and TWICE groups, a twice-monthly administration was advantageous, as it required a lower dose of CERA. © 2014 The Authors.

1992-01-01

Full Text Available Induction of intraoperative pupillary constriction, is predominantly a prostaglandin mediated process. The most potent antiprostaglandin NSAID, Flurbiprofen was used topically to study its efficacy against the above. In a prospective double blind clinical study, 50 brown eyes undergoing planned E.C.C.E., the pupils were dilated with 10% phenylephrine and 2% homatropine 1%/tropicamide. 25 eyes received 0.03% Flurbiprofen-Na+ eye drops 1/2 hourly starting two hours before surgery. The maintained intraoperative mydriasis in the two groups before anterior chamber entry (stage I vs at the end of complete cortex wash (stage III was: in control group (stage I 8.46 +/- 0.48 mm vs (stage III 3.56 +/- 0.43 mm (highly SS; in flurbiprofen group (stage I 8.60 +/- 0.48 mm vs (stage III 8.01 +/- 0.63 mm (NSS. The pupillary area available for surgical manipulation in the control group was significantly decreased from 56.18 mm2 in state I to 9.94 mm2 in stage III, while in flurbiprofen group it changed insignificantly from 58.05 mm2 in stage I to 50.24 mm2 in stage III. Postoperatively after cataract was observed in 44% eyes of control group as compared to only 8% of eyes of flurbiprofen group. Thus a maintained intraoperative mydriasis in flurbiprofen group led to better E.C.L.E. which is a mandatory prerequisite to preferred and better present day posterior chamber IOL implantation.

Maintaining knowledge, training and infrastructure for research and development in nuclear safety - INSAG-16. A report by the International Nuclear Safety Advisory Group

International Nuclear Information System (INIS)

2003-01-01

The purpose of this report is to emphasize the importance of maintaining capabilities for nuclear research and education, especially with regard to safety aspects, so that nuclear safety may be maintained in IAEA Member States, and to alert Member States to the potential for significant harm if the infrastructure for research, development and education is not maintained. If the infrastructure for nuclear safety is not maintained, there will be a steady decrease in expertise, and thus in capability to respond to new challenges. The lead time in developing replacement educational opportunities is very long, because most institutions will require an indication of the number of enthusiastic potential students before investing in new infrastructure, and potential students may look elsewhere in the absence of an exciting analytical and experimental programme and a growing career field. Once lost, it would require massive inputs of resources from many IAEA Member States to attempt to re-establish the infrastructure, as was done to establish it when nuclear technology was new. The result could be a downward spiral in which expertise is lost, influence of the technical community on the decision making process is diminished, and complacency, fed by diminished technical capability, begins to exert a strong effect. In view of the above, INSAG has the following recommendations: In order to maintain and further enhance the safety of nuclear facilities and to protect workers and the public and the environment from radiological consequences, the infrastructure for safety research (experimental facilities, highly competent staff and modern analytical tools) must be maintained and supported by the responsible governmental organizations as well as by the operating organizations and manufacturers. This support should include international networking and co-operation, including joint funding of centres of excellence that have facilities and equipment for use in nuclear research

Gossip Versus Punishment: The Efficiency of Reputation to Promote and Maintain Cooperation

2016-01-01

Prior theory suggests that reputation spreading (e.g., gossip) and punishment are two key mechanisms to promote cooperation in groups, but no behavioral research has yet examined their relative effectiveness and efficiency in promoting and maintaining cooperation. To examine these issues, we observed participants interacting in a four-round public goods game (PGG) with or without gossip and punishment options, and a subsequent two-round trust game (TG). We manipulated gossip as the option to send notes about other group members to these members’ future partners, and punishment as the option to assign deduction points to reduce other group members’ outcomes with a fee-to-fine ratio of 1:3. Findings revealed that in the four-round PGG, the option to gossip increased both cooperation and individual earnings, whereas the option to punish had no overall effect on cooperation (but a positive effect on cooperation in the last two rounds of the PGG) and significantly decreased individual earnings. Importantly, the initial option to gossip made people more trusting and trustworthy in the subsequent TG when gossip was no longer possible, compared to the no-gossip condition. Thus, we provide some initial evidence that gossip may be more effective and efficient than punishment to promote and maintain cooperation. PMID:27039896

Engelmann, Jan M; Herrmann, Esther; Tomasello, Michael

2018-02-01

The motivation to build and maintain a positive personal reputation promotes prosocial behavior. But individuals also identify with their groups, and so it is possible that the desire to maintain or enhance group reputation may have similar effects. Here, we show that 5-year-old children actively invest in the reputation of their group by acting more generously when their group's reputation is at stake. Children shared significantly more resources with fictitious other children not only when their individual donations were public rather than private but also when their group's donations (effacing individual donations) were public rather than private. These results provide the first experimental evidence that concern for group reputation can lead to higher levels of prosociality.

Awakening: a qualitative study on maintaining weight loss after bariatric surgery.

Liebl, Lori; Barnason, Susan; Brage Hudson, Diane

2016-04-01

To describe the experiences of adults who were successful in maintaining weight loss after bariatric surgery. The majority of studies examine a homogenous demographic group of postbariatric surgical patients who have gone through initial weight loss, which occurs within the first 12-24 months post surgery. Maintenance of weight loss begins 24 months after bariatric surgery; however, there is a paucity of research examining experiences during this period. The lack of conclusive research related to interactions between intrapersonal, behavioural and environmental influences suggests a need to develop a better understanding of patients' experiences related to weight loss maintenance post bariatric surgery. Bandura's Social Cognitive Theory provided the framework for the semi-structured interviews for this qualitative descriptive study. In-person interviews with n = 14 participants who were able to maintain weight loss at least 24 months after a bariatric surgery. Participants experienced an awakening and gained a new perspective on their life. They identified negative attitudes, influences and behaviours and modified their environment to support their desired healthy behaviour. To maintain weight loss, an individual must seek out and be surrounded by positive family and peer support influences. Positive support may provide the opportunity for an individual to place personal health needs as a priority. Therapeutic education and counselling for individuals, couples and families should occur during all phases of bariatric surgery. Communication techniques may empower clients to deflect negative comments and influences in a constructive manner. Support groups should accommodate the various phases of bariatric surgery. Clients should be prepared for how to work through emotions associated with weight fluctuations. © 2016 John Wiley & Sons Ltd.

ADAS Update and Maintainability

Science.gov (United States)

Watson, Leela R.

2010-01-01

Since 2000, both the National Weather Service Melbourne (NWS MLB) and the Spaceflight Meteorology Group (SMG) have used a local data integration system (LOIS) as part of their forecast and warning operations. The original LOIS was developed by the Applied Meteorology Unit (AMU) in 1998 (Manobianco and Case 1998) and has undergone subsequent improvements. Each has benefited from three-dimensional (3-D) analyses that are delivered to forecasters every 15 minutes across the peninsula of Florida. The intent is to generate products that enhance short-range weather forecasts issued in support of NWS MLB and SMG operational requirements within East Central Florida. The current LDIS uses the Advanced Regional Prediction System (ARPS) Data Analysis System (AD AS) package as its core, which integrates a wide variety of national, regional, and local observational data sets. It assimilates all available real-time data within its domain and is run at a finer spatial and temporal resolution than current national or regional-scale analysis packages. As such, it provides local forecasters with a more comprehensive understanding of evolving fine-scale weather features. Over the years, the LDIS has become problematic to maintain since it depends on AMU-developed shell scripts that were written for an earlier version of the ADAS software. The goals of this task were to update the NWS MLB/SMG LDIS with the latest version of ADAS, incorporate new sources of observational data, and upgrade and modify the AMU-developed shell scripts written to govern the system. In addition, the previously developed ADAS graphical user interface (GUI) was updated. Operationally, these upgrades will result in more accurate depictions of the current local environment to help with short-range weather forecasting applications, while also offering an improved initialization for local versions of the Weather Research and Forecasting (WRF) model used by both groups.

The aim of the present study is to evaluate whether the effects of a short, six session version of an evidence-based parent training programme (The Incredible Years), delivered in a non-clinical community sample in the northern Norway, are maintained 4 years following the initial intervention. Data were collected primarily from mothers in a randomized controlled trial (N = 117). Children's mean age at 4 year follow-up was 7.5 years. A mixed model analyses of linear change with a time by condition interaction revealed that statistically significant differences were maintained between the parent training and control groups for several outcomes. The parent training group showed a reduction in harsh disciple and an increase of both self-reported positive parenting and parental efficacy when compared to the control group who received services as usual. No significant differences between the two groups were found for child behaviour problems as measured by the ECBI Intensity scale. In addition, mixed model analyses of quadratic change were conducted to test the differences in the trajectory of change over four time points. There were significant differences in the trajectory of change for (1) the ECBI with the parent training group showing an immediate drop in the intensity of problem behaviour and (2) the positive parenting scale showing an immediate steep increase; no other significant differences in trajectory were detected. Families from a non-clinical sample who participated in a brief version of the Incredible Years Basic parent training programme maintained changes in positive parenting, harsh discipline, and parental efficacy 4 years after completion of the intervention.

Early orthodontic interventions are often initiated in the developing dentition to promote favourable developmental changes. Interceptive orthodontic can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. The safest way to prevent future malocclusions from tooth loss is to place a space maintainer that is effective and durable. An appropriate use of space maintainer is advocated to hold the space until the eruption of permanent teeth. This case report describes the various changing trends in use of space maintainers: conventional band and loop, prefabricated band with custom made loop and glass fibre reinforced composite resins as space maintainers.

Maintainability effectiveness evaluations and enhancement

International Nuclear Information System (INIS)

Seminara, J.L.

1985-01-01

In the mid-seventies EPRI initiated a research project to review the human factors aspects of nuclear power plant control rooms. In the course of investigating operator-control room interfaces in five operational control rooms, it became evident that many plant outages had either been caused or prolonged by human factors problems associated with maintenance activities. Consequently, as one of several follow-on projects, EPRI sponsored a review of nine power plants (five nuclear and four fossil) to examine the human factors aspects of plant maintainability. This survey revealed a wide variety of generic human factors problems that could negatively impact the effectiveness of plant maintenance personnel. It was clear that plant maintainability features deserved no less attention to human factors concerns than the operational features of the control room. This paper describes subsequent EPRI-initiated efforts to assist the utilities in conducting self-reviews of maintainability effectiveness and effect needed enhancements

To compare the cardiopulmonary effects of propofol total intravenous anaesthesia (TIVA) with isoflurane in cheetahs (Acinonyx jubatus) to evaluate feasibility for field use. Prospective clinical study. A group of 24 adult cheetahs, 12 per group. Cheetahs were immobilized with zolazepam/tiletamine (1.2 mg kg -1 ) and medetomidine [40 μg kg -1 , both intramuscular (IM)] by darting. A maintenance protocol of propofol TIVA (group P) or isoflurane inhalation (group I) was assigned randomly to each cheetah. Anaesthesia was maintained for at least 60 minutes. Cheetahs breathed spontaneously throughout; oxygen was supplemented at 3 L minute -1 . Cardiopulmonary parameters were recorded at 5 minute intervals and three arterial blood gas samples were analysed. Following maintenance, atipamezole was administered IM (200 μg kg -1 ) and recovery was observed. Data are reported as mean±standard deviation; variables over time were compared using a linear mixed model (fixed: time, treatment; random: cheetah). Lack of response to manipulations was maintained in all cases (end-tidal isoflurane percentage 1.1±0.1%, propofol rate maintained at 0.1 mg kg -1  minute -1 ). The heart and respiratory rates were acceptable throughout maintenance. The end-tidal carbon dioxide tension increased slowly [44.0±5.0 mmHg (5.87±0.67 kPa)] with no differences between groups. All cheetahs were initially markedly hypertensive [mean arterial blood pressure (MAP): (163±17 mmHg)]. The MAP normalized for group I (125±30 mmHg) but remained high for group P (161±17 mmHg) (p < 0.001). Arterial carbon dioxide tension [48.9±14.6 mmHg (6.52±1.95 kPa)] never differed between groups. Initial arterial oxygen tension indicated borderline hypoxaemia, but improved with oxygen supplementation. Recovery time was 10.8±5.0 and 51.9±23.5 minutes for group I and group P, respectively. Both protocols provided acceptable cardiopulmonary values. Propofol may be an alternative to isoflurane

The viability of periodontal ligament (PDL) cells is a significant determinant of the long-term prognosis of replanted avulsed teeth. A storage medium is often required to maintain the viability of these cells during the extra-alveolar period. Many studies have been carried out to search for the most suitable storage medium for avulsed teeth, but an ideal solution has not yet been found. The purpose of the study was to compare and analyze the ability of coconut milk and probiotic milk to maintain PDL cell viability. In an in vitro setting, 69 caries free human premolars with normal periodontium that had been extracted for orthodontic purposes were randomly divided into two experimental groups on the basis of storage media used (i.e., coconut milk or probiotic milk) and a Hanks' balanced salt solution (HBSS) control group (23 samples per group). Immediately after extraction, the teeth were stored dry for 20 min and then immersed for 30 min in one of the storage media. The teeth were then subjected to collagenase-dispase assay and labeled with 0.5% trypan blue staining solution for determination of cell viability. The number of viable cells was counted under a light microscope and statistically analyzed using anova and post hoc Tukey test (P ≤ 0.05). Statistical analysis demonstrated there was a significant difference (P coconut milk and probiotic milk as well as HBSS in maintaining cell viability. However, there was no significant difference between probiotic milk and HBSS in ability to maintain PDL cell viability (P > 0.05). Coconut milk may not be suitable as an interim transport media due to poor maintenance of cell viability. However, probiotic milk was able to maintain PDL cell viability as well as HBSS. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To evaluate the monitoring of metabolic parameters among outpatients maintained on antipsychotic medications in a general hospital setting in Malaysia and to assess the impact of a local monitoring protocol. By performing a baseline audit of files from a random sample of 300 patients prescribed antipsychotic medications for at least 1 year; we determined the frequency of metabolic monitoring. The findings informed the design of a new local protocol, on which clinical staff was briefed. We re-evaluated metabolic monitoring immediately after implementation, in a small sample of new referrals and current patients. We explored staff perceptions of the initiative with a follow-up focus group, 6 months post-implementation. The baseline audit revealed a sub-optimal frequency of metabolic parameter recording. Re-audit, following implementation of the new protocol, revealed improved monitoring but persisting deficits. Dialogue with the clinical staff led to further protocol modification, clearer definition of staff roles and use of a standard recording template. Focus group findings revealed positive perceptions of the initiative, but persisting implementation barriers, including cultural issues surrounding waist circumference measurement. Responding to challenges in achieving improved routine metabolic monitoring of patients maintained on antipsychotics required on-going dialogue with the clinical staff, in order to address both service pressures and cultural concerns. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Maintaining steam/condensate lines

International Nuclear Information System (INIS)

Russum, S.A.

1992-01-01

Steam and condensate systems must be maintained with the same diligence as the boiler itself. Unfortunately, they often are not. The water treatment program, critical to keeping the boiler at peak efficiency and optimizing operating life, should not stop with the boiler. The program must encompass the steam and condensate system as well. A properly maintained condensate system maximizes condensate recovery, which is a cost-free energy source. The fuel needed to turn the boiler feedwater into steam has already been provided. Returning the condensate allows a significant portion of that fuel cost to be recouped. Condensate has a high heat content. Condensate is a readily available, economical feedwater source. Properly treated, it is very pure. Condensate improves feedwater quality and reduces makeup water demand and pretreatment costs. Higher quality feedwater means more reliable boiler operation

Maintaining knowledge, training and infrastructure for research and development in nuclear safety. INSAG-16. A report by the International Nuclear Safety Advisory Group (Russian Edition)

International Nuclear Information System (INIS)

2015-01-01

The purpose of this report is to emphasize the importance of maintaining capabilities for nuclear research and education, especially with regard to safety aspects, so that nuclear safety may be maintained in IAEA Member States, and to alert Member States to the potential for significant harm if the infrastructure for research, development and education is not maintained. If the infrastructure for nuclear safety is not maintained, there will be a steady decrease in expertise, and thus in capability to respond to new challenges. The lead time in developing replacement educational opportunities is very long, because most institutions will require an indication of the number of enthusiastic potential students before investing in new infrastructure, and potential students may look elsewhere in the absence of an exciting analytical and experimental programme and a growing career field. Once lost, it would require massive inputs of resources from many IAEA Member States to attempt to re-establish the infrastructure, as was done to establish it when nuclear technology was new. The result could be a downward spiral in which expertise is lost, influence of the technical community on the decision making process is diminished, and complacency, fed by diminished technical capability, begins to exert a strong effect. In view of the above, INSAG has the following recommendations: In order to maintain and further enhance the safety of nuclear facilities and to protect workers and the public and the environment from radiological consequences, the infrastructure for safety research (experimental facilities, highly competent staff and modern analytical tools) must be maintained and supported by the responsible governmental organizations as well as by the operating organizations and manufacturers. This support should include international networking and co-operation, including joint funding of centres of excellence that have facilities and equipment for use in nuclear research

Effective grouping for energy and performance: Construction of adaptive, sustainable, and maintainable data storage

Science.gov (United States)

Essary, David S.

The performance gap between processors and storage systems has been increasingly critical over the years. Yet the performance disparity remains, and further, storage energy consumption is rapidly becoming a new critical problem. While smarter caching and predictive techniques do much to alleviate this disparity, the problem persists, and data storage remains a growing contributor to latency and energy consumption. Attempts have been made at data layout maintenance, or intelligent physical placement of data, yet in practice, basic heuristics remain predominant. Problems that early studies sought to solve via layout strategies were proven to be NP-Hard, and data layout maintenance today remains more art than science. With unknown potential and a domain inherently full of uncertainty, layout maintenance persists as an area largely untapped by modern systems. But uncertainty in workloads does not imply randomness; access patterns have exhibited repeatable, stable behavior. Predictive information can be gathered, analyzed, and exploited to improve data layouts. Our goal is a dynamic, robust, sustainable predictive engine, aimed at improving existing layouts by replicating data at the storage device level. We present a comprehensive discussion of the design and construction of such a predictive engine, including workload evaluation, where we present and evaluate classical workloads as well as our own highly detailed traces collected over an extended period. We demonstrate significant gains through an initial static grouping mechanism, and compare against an optimal grouping method of our own construction, and further show significant improvement over competing techniques. We also explore and illustrate the challenges faced when moving from static to dynamic (i.e. online) grouping, and provide motivation and solutions for addressing these challenges. These challenges include metadata storage, appropriate predictive collocation, online performance, and physical placement

To determine the effect of maintaining torque after mechanical cycling of abutment screws that are coated with diamondlike carbon and coated with diamondlike carbon doped with diamond nanoparticles, with external and internal hex connections. Sixty implants were divided into six groups according to the type of connection (external or internal hex) and the type of abutment screw (uncoated, coated with diamondlike carbon, and coated with diamondlike carbon doped with diamond nanoparticles). The implants were inserted into polyurethane resin and crowns of nickel chrome were cemented on the implants. The crowns had a hole for access to the screw. The initial torque and the torque after mechanical cycling were measured. The torque values maintained (in percentages) were evaluated. Statistical analysis was performed using one-way analysis of variance and the Tukey test, with a significance level of 5%. The largest torque value was maintained in uncoated screws with external hex connections, a finding that was statistically significant (P = .0001). No statistically significant differences were seen between the groups with and without coating in maintaining torque for screws with internal hex connections (P = .5476). After mechanical cycling, the diamondlike carbon with and without diamond doping on the abutment screws showed no improvement in maintaining torque in external and internal hex connections.

Groupthink: one peril of group cohesiveness.

Science.gov (United States)

Rosenblum, E H

1982-04-01

A group's aim is to make well-conceived, well-understood, well-accepted and realistic decisions to reach their agreed-upon goals. This aim applies equally to their own goals and those occasionally imposed by outsiders such as hospital administration, accreditation committees and the federal government. Effective groupwork requires group cohesion with its components of trust, risk taking, mutual support, and group esteem. With constant vigilance the group can maintain its positive dynamics, so that the unhealthy state of groupthink does not undermine its existence.

Maintainability design and evaluation of mechanical systems based on tribology

International Nuclear Information System (INIS)

Wani, M.F.; Gandhi, O.P.

2002-01-01

Maintainability of mechanical systems based on tribology is suggested and evaluated in this paper. Tribo-features of mechanical systems, which characterise maintainability are identified and are modelled in terms of tribo-maintainability digraph. The nodes in the digraph represent the tribo-features and edges represent the degree of influence among the features. A matrix, one to one representation of the digraph, is defined to develop system maintainability expression (SPF-t) based on the tribology. It is also useful in comparing the various design alternatives from tribo-maintainability point of view. Maintainability is evaluated from the tribo-maintainability index, obtained from SPF-t (i.e. permanent of the matrix) by substituting the numerical values of the features and their interdependence. A higher value of the index implies better maintainability of the systems. The proposed methodology also guides designers in enhancing the maintainability of a system by appropriately incorporating tribo-features. An example to illustrate the methodology is also presented

2007-06-01

Full Text Available Four sets of rice isonuclear-alloplasmic lines including 16 male sterile lines and their maintainer lines were analyzed by using 91 pairs of SSR primers to study the genetic diversity of nuclear genome and their relative relationships. A total of 169 alleles were detected in the 16 lines, with a frequency of polymorphic loci of 53.85% and an average number of alleles per locus of 1.8, and the average gene diversity was 0.228. Four sets of the isonuclear-alloplasmic male sterile lines shared 146 identical alleles, corresponding to 86.39% of the total alleles; meanwhile, there are 23 different alleles among the tested materials, being 13.61% of the total alleles. On average, 78.70% identical alleles and 21.30% different alleles of the total alleles were detected between the isonuclear-alloplasmic male sterile lines and their maintainer lines. There were 53.85% identical alleles and 46.15% different alleles of the total alleles among the homozygous allonucleus male sterile lines. The fingerprints were established for some male sterile lines and maintainer lines. All the materials tested were divided into three groups at the 0.2 genetic distance based on the cluster analysis. Eight lines of Huanong A and Huayu A (including Huanong B and Huayu B were in the first group, four lines of Kezhen A (including Kezhen B in the second group, and four lines of Zhenshan 97A (including Zhenshan 97B in the third group. For the isonuclear-alloplasmic male sterile lines, the similarity coefficient between Y (Yegong type and WA (wild abortive type or between CW (Raoping wild rice and WA type reached 87–98%.

Meal consumption is ineffective at maintaining or correcting water balance in a desert lizard, Heloderma suspectum.

Science.gov (United States)

Wright, Christian D; Jackson, Marin L; DeNardo, Dale F

2013-04-15

Many xeric organisms maintain water balance by relying on dietary and metabolic water rather than free water, even when free water may be available. For such organisms, hydric state may influence foraging decisions, since meal consumption is meeting both energy and water demands. To understand foraging decisions it is vital to understand the role of dietary water in maintaining water balance. We investigated whether meal consumption was sufficient to maintain water balance in captive Gila monsters (Heloderma suspectum) at varying levels of dehydration. Gila monsters could not maintain water balance over long time scales through meal consumption alone. Animals fed a single meal took no longer to dehydrate than controls when both groups were deprived of free water. Additionally, meal consumption imparts an acute short-term hydric cost regardless of hydration state. Meal consumption typically resulted in a significant elevation in osmolality at 6 h post-feeding, and plasma osmolality never fell below pre-feeding levels despite high water content (~70%) of meals. These results failed to support our hypothesis that dietary water is valuable to Gila monsters during seasonal drought. When considered in conjunction with previous research, these results demonstrate that Gila monsters, unlike many xeric species, are heavily reliant on seasonal rainfall and the resulting free-standing water to maintain water balance.

Full Text Available Falls are common among people with intellectual disabilities. In literature there is a limited number of studies which deal with this problem. The main objective of this research is to analyze the ability to maintain postural balance in adolescents with mild intellectual disability (ID by comparing it to their peers who do not have ID. The sample included 64 male adolescents, aged 16 to 18, out of which 32 belonged to the experimental group (e-group and had mild ID, while the control group (c-group consisted of 32 adolescents of typical population. The ability to maintain postural balance in both groups was tested by using three tests: Expanded Timed Up and Go Test (ETUGT, Modified Functional Reach Test (M-FRT and One-leg Stance (OLS. The research was conducted in the period from 2008 to 2010 in 'Petar Leković' Secondary School, Belgrade (Serbia, as well as in the Institution for people with special needs 'Caritas' in Mostar (Bosnia and Herzegovina. The results show that the use of ETUG test showed a statistically significant difference between the groups in terms of time needed for the completion of the test, while on the M-FR test the participants from e-group achieved significantly lower results than the c-group. The OLS test showed that the participants of both groups completed the test equally well on both legs when not blindfolded, while the experimental group achieved significantly lower results on both legs when blindfolded. The results suggest that adolescents with ID achieve lower results on most of the applied postural balance tests when compared to typical adolescent population.

Advanced remotely maintainable force-reflecting servomanipulator concept

International Nuclear Information System (INIS)

Kuban, D.P.; Martin, H.L.

1984-01-01

A remotely maintainable force-reflecting servomanipulator concept is being developed at the Oak Ridge National Laboratory as part of the Consolidated Fuel Reprocessing Program. This new manipulator addresses requirements of advanced nuclear fuel reprocessing with emphasis on force reflection, remote maintainability, reliability, radiation tolerance, and corrosion resistance. The advanced servomanipulator is uniquely subdivided into remotely replaceable modules which will permit in situ manipulator repair by spare module replacement. Manipulator modularization and increased reliability are accomplished through a force transmission system that uses gears and torque tubes. Digital control algorithms and mechanical precision are used to offset the increased backlash, friction, and inertia resulting from the gear drives. This results in the first remotely maintainable force-reflecting servomanipulator in the world. 10 references, 4 figures, 1 table

Evolving Reliability and Maintainability Allocations for NASA Ground Systems

2016-01-01

This paper describes the methodology and value of modifying allocations to reliability and maintainability requirements for the NASA Ground Systems Development and Operations (GSDO) programs subsystems. As systems progressed through their design life cycle and hardware data became available, it became necessary to reexamine the previously derived allocations. This iterative process provided an opportunity for the reliability engineering team to reevaluate allocations as systems moved beyond their conceptual and preliminary design phases. These new allocations are based on updated designs and maintainability characteristics of the components. It was found that trade-offs in reliability and maintainability were essential to ensuring the integrity of the reliability and maintainability analysis. This paper discusses the results of reliability and maintainability reallocations made for the GSDO subsystems as the program nears the end of its design phase.

The social, political and economic reforms of 1992 in Russia led to a decade of rising income inequality, unemployment and economic crises, the most severe of which occurred in 1998. This study assesses dietary trends for children in low and high income households during this politically and economically unstable period from 1994 to 2000. Several possible food-related behaviors were also assessed to evaluate coping strategies adopted in the face of decreasing economic stability. Low income children maintained a steady energy intake per kilogram weight throughout the study period (251.0-259.4 kJ/kg), whereas intake for high income children increased significantly to a per capital average of 297.1 kJ/kg by 2000. At the food group level, the trend in per capita intake for all food groups was maintained for low income children except for a 22% decrease in meat and poultry consumption (P economic crisis.

Developing maintainability for fusion power systems. Final report

1979-11-01

The overall purpose of the study is to identify design features of fusion power reactors which contribute to the achievement of high levels of maintainability. Previous phases evaluated several commercial tokamak reactor design concepts. This final phase compares the maintainability of a tandem mirror reactor (TMR) commercial conceptual design with the most maintainable tokamak concept selected from earlier work. A series of maintainability design guidelines and desirable TMR design features are defined. The effects of scheduled and unscheduled maintenance for most of the reactor subsystems are defined. The comparison of the TMR and tokamak reactor maintenance costs and availabilities show that both reactors have similar costs for scheduled maintenance at 19.4 and 20.8 million dollars annually and similar scheduled downtime availability impacts, achieving approximate availabilities of 79% at optimized maintenance intervals and cost of electricity.

The overall purpose of the study is to identify design features of fusion power reactors which contribute to the achievement of high levels of maintainability. Previous phases evaluated several commercial tokamak reactor design concepts. This final phase compares the maintainability of a tandem mirror reactor (TMR) commercial conceptual design with the most maintainable tokamak concept selected from earlier work. A series of maintainability design guidelines and desirable TMR design features are defined. The effects of scheduled and unscheduled maintenance for most of the reactor subsystems are defined. The comparison of the TMR and tokamak reactor maintenance costs and availabilities show that both reactors have similar costs for scheduled maintenance at 19.4 and 20.8 million dollars annually and similar scheduled downtime availability impacts, achieving approximate availabilities of 79% at optimized maintenance intervals and cost of electricity

Polarization maintaining optical fibers can be used to transmit linearly polarized light over long distances but their use in cryogenic environments has been limited by their sensitivity to temperature changes and associated mechanical stress. We investigate experimentally how thermal stresses affect the polarization maintaining fibers and model the observations with Jones matrices. We describe the design, construction, and testing of a feedthrough and fiber termination assembly that uses polarization maintaining fiber to transmit light from a 633 nm HeNe laser at room temperature to a homodyne polarization-based interferometer in a cryogenic vacuum. We report on the efficiency of the polarization maintaining properties of the feedthrough assembly. We also report that, at cryogenic temperatures, the interferometer can achieve a sensitivity of 8 × 10(-10) rad/√Hz at 0.05 Hz using this feedthrough.

Full Text Available Abstract Background Sequences homologous to the gypsy retroelement from Drosophila melanogaster are widely distributed among drosophilids. The structure of gypsy includes an open reading frame resembling the retroviral gene env, which is responsible for the infectious properties of retroviruses. Results In this study we report molecular and phylogeny analysis of the complete env gene from ten species of the obscura group of the genus Drosophila and one species from the genus Scaptomyza. Conclusion The results indicate that in most cases env sequences could produce a functional Env protein and therefore maintain the infectious capability of gypsy in these species.

Maintaining protein composition in cilia.

Stephen, Louise A; Elmaghloob, Yasmin; Ismail, Shehab

2017-12-20

The primary cilium is a sensory organelle that is vital in regulating several signalling pathways. Unlike most organelles cilia are open to the rest of the cell, not enclosed by membranes. The distinct protein composition is crucial to the function of cilia and many signalling proteins and receptors are specifically concentrated within distinct compartments. To maintain this composition, a mechanism is required to deliver proteins to the cilium whilst another must counter the entropic tendency of proteins to distribute throughout the cell. The combination of the two mechanisms should result in the concentration of ciliary proteins to the cilium. In this review we will look at different cellular mechanisms that play a role in maintaining the distinct composition of cilia, including regulation of ciliary access and trafficking of ciliary proteins to, from and within the cilium.

Cf, the methodology and diagnostic standard of 12 collaborative units about "Epidemiological investigation" of 1982, we traced to investigate the relation between the patients' condition outcome and drug maintain therapy of 324 cases with schizophrenia in community. The investigative result showed the cure rate of insisting on taking medicine group was 25.21%, the effective rate was 97.48%, the cure rate of irregular taking medicine groups was 6.63%, the effective rate was 68.37%, there was remarkable difference between the cure rate and the effective rate in two groups. Otherwise we also compared the patients, condition of insisting on taking drug groups with during investigation. We found there was no remarkable change that showed insisting a drug maintain therapy out the hospital to the curative effect of the disease to possess on important meaning. The pattern also compared the curative effect of a time onset of disease group and many times. There was no remarkable difference about the statistical analysis of the curative effect among each group. It showed me never lose confidence to the patients. We should treat actively them.

Human cooperation by lethal group competition.

2013-01-01

Why humans are prone to cooperate puzzles biologists, psychologists and economists alike. Between-group conflict has been hypothesized to drive within-group cooperation. However, such conflicts did not have lasting effects in laboratory experiments, because they were about luxury goods, not needed for survival ("looting"). Here, we find within-group cooperation to last when between-group conflict is implemented as "all-out war" (eliminating the weakest groups). Human subjects invested in helping group members to avoid having the lowest collective pay-off, whereas they failed to cooperate in control treatments with random group elimination or with no subdivision in groups. When the game was repeated, experience was found to promote helping. Thus, not within-group interactions alone, not random group elimination, but pay-off-dependent group elimination was found to drive within-group cooperation in our experiment. We suggest that some forms of human cooperation are maintained by multi-level selection: reciprocity within groups and lethal competition among groups acting together.

To determine whether heparinized saline would be more effective in maintaining the patency of peripheral IV catheters in dogs compared to 0.9% sodium chloride. Prospective blinded randomized study. University Veterinary Teaching Hospital. Thirty healthy purpose bred dogs, intended for use in the junior surgery laboratory, were utilized. The dogs were randomized into 1 of 3 groups, 2 treatment groups and a control group. An 18-Ga cephalic catheter was placed in the cephalic vein of each dog. Each dog in the treatment group had their catheter flushed with either 10 IU/mL heparinized saline or 0.9% sodium chloride every 6 hours for 42 hours. The dogs in the control group did not have their catheters flushed until the end of the study period. Immediately prior to flushing catheters, each catheter was evaluated for patency by aspiration of blood and the catheter site was evaluated for phlebitis. All dogs in the heparinized saline and 0.9% sodium chloride group had catheters that flushed easily at each evaluation point. More dogs in the saline group had catheters from which blood could not be aspirated, but there was no significant difference between these groups. All dogs in the control group had catheters that flushed easily at the end of the assigned 6 hour interval except in 1 dog. Phlebitis was not detected in any dog. Flushes of 0.9% sodium chloride were found to be as effective as 10 IU/mL heparinized saline flushes in maintaining patency of 18-Ga peripheral venous catheters in dogs for up to 42 hours. For peripheral catheters placed with the intention of performing serial blood draws, heparinized flushes may be warranted. © Veterinary Emergency and Critical Care Society 2013.

Full Text Available The aim of this research was to study the effect of spot variations on shear strength of spot welds in an electric loop space maintainer. Stainless steel wire of 0.8 mm diameter and nickel chromium crwon for lower second molar of temporary teeth were used. A loop 1 cm wide, made of 3.5 cm stainless steel wire, was welded with 3 dots on the crown using an electric spot welder. Each dot for each group took different spot variations from 1 X – 4 X. A loop space maintainer made with the usual materials and techniques as applied at the IKGA FKG UI Clinic was used as a control, with a torch as heat source. Ten specimens each were prepared for shear testing and three spesimens each for metallography. Universal testing machine was used for shear strength testing at a crosshead speed of 0.5 mm/min, and SEM/EDS was used for metallography and fractography. The data were statistically analyzed with one-way ANOVA at p = 0.05, and Tukey post hoc test. The results show that the shear strength of the welded loop space maintainer was higher than that of a soldered loop space maintainer, although the difference was not statistically significant with spot variation 1 X. SEM/EDS analysis suggests that a new alloy forms at the contact area of welded and soldered loop space maintainer. Fractography of the joints suggests that welds are better than soldered joints, with higher ductility and toughness, as can be seen from the dimpled pattern of the welded joint and cleavage patterns in the control joints. In conclusion, the loop space maintainer is better made by welding than by soldering.

This article is a report of a study undertaken to understand how nurses maintain patients' dignity in clinical practice. Dignity is a core concept in nursing care and maintaining patients' dignity is critical to their recovery. In Western countries, measures to maintain dignity in patients' care include maintaining privacy of the body, providing spatial privacy, giving sufficient time, treating patients as a whole person and allowing patients to have autonomy. However, this is an under-studied topic in Asian countries. For this qualitative descriptive study, data were collected in Taiwan in 2009 using in-depth interviews with a purposive sample of 30 nurses from a teaching hospital in eastern Taiwan. The audiotaped interviews were transcribed verbatim and analysed using content analysis. Nurses' measures to maintain dignity in patient care were captured in five themes: respect, protecting privacy, emotional support, treating all patients alike and maintaining body image. Participants did not mention beneficence, a crucial element achieved through the professional care of nurses that can enhance the recovery of patients. In-service education to help nurses enhance dignity in patient care should emphasize emotional support, maintaining body image and treating all patients alike. Our model for maintaining dignity in patient care could be used to develop a clinical care protocol for nurses to use in clinical practice. © 2010 Blackwell Publishing Ltd.

Disturbance maintains alternative biome states.

Dantas, Vinícius de L; Hirota, Marina; Oliveira, Rafael S; Pausas, Juli G

2016-01-01

Understanding the mechanisms controlling the distribution of biomes remains a challenge. Although tropical biome distribution has traditionally been explained by climate and soil, contrasting vegetation types often occur as mosaics with sharp boundaries under very similar environmental conditions. While evidence suggests that these biomes are alternative states, empirical broad-scale support to this hypothesis is still lacking. Using community-level field data and a novel resource-niche overlap approach, we show that, for a wide range of environmental conditions, fire feedbacks maintain savannas and forests as alternative biome states in both the Neotropics and the Afrotropics. In addition, wooded grasslands and savannas occurred as alternative grassy states in the Afrotropics, depending on the relative importance of fire and herbivory feedbacks. These results are consistent with landscape scale evidence and suggest that disturbance is a general factor driving and maintaining alternative biome states and vegetation mosaics in the tropics. © 2015 John Wiley & Sons Ltd/CNRS.

Improving versus maintaining nuclear safety

International Nuclear Information System (INIS)

2002-01-01

The concept of improving nuclear safety versus maintaining it has been discussed at a number of nuclear regulators meetings in recent years. National reports have indicated that there are philosophical differences between NEA member countries about whether their regulatory approaches require licensees to continuously improve nuclear safety or to continuously maintain it. It has been concluded that, while the actual level of safety achieved in all member countries is probably much the same, this is difficult to prove in a quantitative way. In practice, all regulatory approaches require improvements to be made to correct deficiencies and when otherwise warranted. Based on contributions from members of the NEA Committee on Nuclear Regulatory Activities (CNRA), this publication provides an overview of current nuclear regulatory philosophies and approaches, as well as insights into a selection of public perception issues. This publication's intended audience is primarily nuclear safety regulators, but government authorities, nuclear power plant operators and the general public may also be interested. (author)

A Methodology for Integrating Maintainability Using Software Metrics

OpenAIRE

Lewis, John A.; Henry, Sallie M.

1989-01-01

Maintainability must be integrated into software early in the development process. But for practical use, the techniques used must be as unobtrusive to the existing software development process as possible. This paper defines a methodology for integrating maintainability into large-scale software and describes an experiment which implemented the methodology into a major commercial software development environment.

Maintainability analysis considering time-dependent and time-independent covariates

Barabadi, Abbas; Barabady, Javad; Markeset, Tore

2011-01-01

Traditional parametric methods for assessing maintainability most often only consider time to repair (TTR) as a single explanatory variable. However, to predict availability more precisely for high availability systems, a better model is needed to quantify the effect of operational environment on maintainability. The proportional repair model (PRM), which is developed based on proportional hazard model (PHM), may be used to analyze maintainability in the present of covariates. In the PRM, the effect of covariates is considered to be time independent. However this assumption may not be valid for some situations. The aim of this paper is to develop the Cox regression model and its extension in the presence of time-dependent covariates for determining maintainability. A simple case study is used to demonstrate how the model can be applied in a real case.

Significance of grooming behavior in two polygynous groups of western black crested gibbons: Implications for understanding social relationships among immigrant and resident group members.

In primates, grooming is considered among the most common behaviors for maintaining social bonds; however, to date, few studies have examined grooming behavior in gibbon species in detail. We used both a 5-min interval scan method and social network analysis to study grooming in two groups of polygynous western black-crested gibbon (Nomascus concolor) in Wuliang Mountain, Central Yunnan, China. Individuals in both groups spent little time in social grooming (1.45% and 1.97% of active time). We compared the two groups' grooming networks and found that the group that maintained a more stable social unit had a more complex grooming network while the group with new immigrants had a grooming network characterized by fewer grooming pairs. Females in both groups played important roles in the grooming network. A newly immigrant female spent the most time grooming others and chose the resident adult female as her main adult grooming partner. Other females from both groups chose the adult male as their primary grooming partner (except their offspring). A sub-adult male who had resided in his natal group for 2 years after maturing into an adult also groomed more and was at the center of the network. This male finally replaced the breeding male in his group 3 years after our data collection period ended. We hypothesize that the immigrant female and the resident young adult male engaged in more extensive grooming interactions as a behavioral strategy to gain tolerance from long-term residents. Our results suggest that female gibbons in polygynous groups actively cooperate in maintaining social relationships rather than co-exist through tolerance or avoidance. Our observations indicate that grooming networks in crested gibbons reflect individual dynamics and partly support the social cohesion hypothesis for primate grooming. In this regard, we suggest that changes in gibbon grooming networks can be used to predict social change. © 2013 Wiley Periodicals, Inc.

Barrett, Andrew C; Negus, S Stevens; Mello, Nancy K; Caine, S Barak

2005-11-01

Recent studies indicate that GABAergic ligands modulate abuse-related effects of cocaine. The goal of this study was to evaluate the effects of a mechanistically diverse group of GABAergic ligands on the discriminative stimulus and reinforcing effects of cocaine in rats. One group of rats was trained to discriminate 5.6 mg/kg cocaine from saline in a two-lever, food-reinforced, drug discrimination procedure. In two other groups, responding was maintained by cocaine (0-3.2 mg/kg/injection) or liquid food (0-100%) under a fixed ratio 5 schedule. Six GABA agonists were tested: the GABA-A receptor agonist muscimol, the GABA-B receptor agonist baclofen, the GABA transaminase inhibitor gamma-vinyl-GABA (GVG), and three GABA-A receptor modulators (the barbiturate pentobarbital, the high-efficacy benzodiazepine midazolam, and the low-efficacy benzodiazepine enazenil). When tested alone, none of the compounds substituted fully for the discriminative stimulus effects of cocaine. As acute pretreatments, select doses of midazolam and pentobarbital produced 2.2- to 3.6-fold rightward shifts in the cocaine dose-effect function. In contrast, muscimol, baclofen, GVG, and enazenil failed to alter the discriminative stimulus effects of cocaine. In assays of cocaine- and food-maintained responding, midazolam and pentobarbital decreased cocaine self-administration at doses 9.6- and 3.3-fold lower, respectively, than those that decreased food-maintained responding. In contrast, muscimol, baclofen, and GVG decreased cocaine self-administration at doses that also decreased food-maintained responding. Enazenil failed to alter cocaine self-administration. Together with previous studies, these data suggest that among mechanistically diverse GABA agonists, high-efficacy GABA-A modulators may be the most effective for modifying the abuse-related effects of cocaine.

Genetic and somatic effects in animals maintained on tritiated water

1982-01-01

Somatic and genetic effects of the continuous ingestion of tritiated water (HTO) at concentrations of 0.3, 1.0 and 3.0 μCi/ml were investigated in mice of the Hale-Stoner-Brookhaven strain. At these levels, there was no measurable somatic effect. Although genetic effects as measured by dominant lethal mutation (DLM) assay indicated a significant effect (P>0.01) on the number of viable embryos and early deaths in the 3.0 μCi/ml HTO group and on the number of viable embryos in the 1.0 μCi/ml HTO group, no genetic effects were significantly noted in the 0.3 μCi/ml HTO group. Liver cytogenetic studies showed a significant increase in the number of abnormal cells in the 3.0 μCi/ml HTO group. A reduction in bone marrow stem cells, without an attendant reduction in total marrow cellularity, was noted in the 3.0 and 1.0 μCi/ml HTO groups. There was no significant difference in any of the DLM parameters between animals maintained on 3.0 μCi/ml of HTO and animals exposed to the equivalent 137 Cs gamma dose (22 hours/day exposure). Consideration of the relative amounts and biological half lives of tritium present in the nucleus as water, DNA and histone suggests that after transient exposure to tritiated water, nearly all significant radiation damage can be attributed to tritium present in the nucleus as water. These data suggest that hazards from tritium attendant with normal reactor operation should not at this time be considered as a deterrent to the further development of fission and/or fusion reactor technology.

2011-01-01

This study investigated the association between self-reported good health and self-valued good social life. An additional aim was to examine entrepreneur's strategies for maintaining good health. The study design included a two-wave questionnaire, with five years between the surveys (2001 and 2006), and qualitative interviews. The study group consisted of 246 entrepreneurs from the central region of Sweden and represented ten different trades. Entrepreneurs reporting good health in both 2001 and 2006 were compared with entrepreneurs reporting poor health on both occasions or with inconsistent answers. Six of the entrepreneurs were strategically chosen for the interview study. Consistent good health was reported by 56% of the entrepreneurs. Good social life in 2001 was associated with an increased odds ratio (OR) for consistent good health when the analyses were adjusted for physical work conditions and job satisfaction (OR 2.12, 95% CI 1.07-4.17). Findings for good leisure time, weekly moderate physical exercise, and a rating of work being less or equally important as other life areas, were similar but not statistically significant when job satisfaction was considered in the analyses. Strategies for maintaining good health included good planning and control over work, flexibility at work, good social contact with family, friends and other entrepreneurs, and regular physical exercise. This study demonstrated an association between self-reported good health and good social life for entrepreneurs in small-scale enterprises. In addition, the entrepreneurs emphasised strategies such as planning and control over work and physical exercise are important for maintaining good health.

Human sclera maintains common characteristics with cartilage throughout evolution.

Directory of Open Access Journals (Sweden)

Yuko Seko

Full Text Available BACKGROUND: The sclera maintains and protects the eye ball, which receives visual inputs. Although the sclera does not contribute significantly to visual perception, scleral diseases such as refractory scleritis, scleral perforation and pathological myopia are considered incurable or difficult to cure. The aim of this study is to identify characteristics of the human sclera as one of the connective tissues derived from the neural crest and mesoderm. METHODOLOGY/PRINCIPAL FINDINGS: We have demonstrated microarray data of cultured human infant scleral cells. Hierarchical clustering was performed to group scleral cells and other mesenchymal cells into subcategories. Hierarchical clustering analysis showed similarity between scleral cells and auricular cartilage-derived cells. Cultured micromasses of scleral cells exposed to TGF-betas and BMP2 produced an abundant matrix. The expression of cartilage-associated genes, such as Indian hedge hog, type X collagen, and MMP13, was up-regulated within 3 weeks in vitro. These results suggest that human 'sclera'-derived cells can be considered chondrocytes when cultured ex vivo. CONCLUSIONS/SIGNIFICANCE: Our present study shows a chondrogenic potential of human sclera. Interestingly, the sclera of certain vertebrates, such as birds and fish, is composed of hyaline cartilage. Although the human sclera is not a cartilaginous tissue, the human sclera maintains chondrogenic potential throughout evolution. In addition, our findings directly explain an enigma that the sclera and the joint cartilage are common targets of inflammatory cells in rheumatic arthritis. The present global gene expression database will contribute to the clarification of the pathogenesis of developmental diseases such as high myopia.

Currently, inside the oral cavity, the dental space maintainers are subjected to forces exerted on them when performing various functions; therefore, it is important to know how each of these mechanisms behave and respond to forces that are applied directly to them. The mechanical properties of the materials used in dentistry are defined by a set of characteristics representing the behaviour of their particular working conditions and it is qualitatively expressed by a number of parameters.The study aimed to determine the pressing force that can be taken by four 4 types of space maintainers frequently used in practice - fixed and removable, applied on four samples realized with human teeth extracted for orthodontic purposes. Static tests were carried out on a machine type short WDW-5 EC with a maximum force of 5 kN and a loading speed of 5 mm/min by a special testing machine, with an innovative appliance; data recording was automatically performed, using a computer with a special program that present the specific diagrams. Experimental determinations included the following aspects: to determine the maximum force that can be supported by each sample, and to observe the deformations. The values obtained indicate that the best option in terms of behavior under the conditions specified is the removable appliance, and the less functional version is the fixed space maintainer using brackets. According to tests conducted, the fracture strength was found to be more important for fixed space maintainers (band and loop, for example) so, in practice is using more frequent these types of space maintainers.

A prescription for health: a primary care based intervention to maintain the non-smoking status of young people.

Fidler, W; Lambert, T W

2001-03-01

To evaluate the effectiveness of primary health care teams in maintaining a group of young people aged 10--15 years as non-smokers. Randomised controlled trial using postal questionnaires. Oxfordshire, UK. 2942 young people who were initially self declared non-smokers. Information about smoking, sent under signature of the subject's general practitioner, certificates and posters intended to reinforce non-smoking behaviour. Changes in smoking behaviour, attitudes measured after one year. After a year, smoking uptake was 7.8% in the control group compared with 5.1% in the intervention group (odds ratio (OR) 1.6, 95% confidence interval (CI) 1.1 to 2.2). Among boys the corresponding results were 5.2% and 2.4% (OR 2.3, 95% CI 1.2 to 4.6), and among girls 10.0% and 7.5% (OR 1.4, 95% CI 0.9 to 2.1). Among boys aged 14-15 the uptake rate was 12.8% in the control group compared with 5.4% in the intervention group. However, among girls of the same age the intervention was less effective, with smoking uptake of 15.1% in the control group and 12.8% in the intervention group. The intervention was more effective among young people whose initial attitudes identified them as definite non-smokers than those who were potential smokers. The intervention substantially reduced smoking uptake among the young people, particularly boys. Primary health care teams can play an important role in maintaining the non-smoking status of their young patients. Confidential postal contact from the doctor direct to the young person at home is influential and cost-effective.

[Factors influencing the sense of unintegration of thoughts in maintaining anger].

Endo, Hiroko; Yukawa, Shintaro

2013-12-01

Endo and Yukawa (2012) investigated the process of maintaining anger and demonstrated that a sense of unintegration of thoughts maintained anger by promoting recurrent thinking and avoidance behavior. Our present study examined how personality characteristics and situational factors affected the process of maintaining anger. Undergraduates (N=713) wrote about an anger episode, and completed questionnaires assessing their sense of unintegration of thoughts, recurrent thinking, avoidance behaviors, and maintaining anger. The questionnaires also assessed personality characteristics such as difficulty in identifying feelings, and situational factors such as the need for maintaining relationships, anger arousability, and meaning-making for the anger episode. The results of covariance structure analysis indicated that difficulties in identifying feelings and anger arousability contributed to maintaining anger by increasing the sense of unintegration of thoughts just after the episode. However, the need for maintaining relationships directly reduced the sense of unintegration of thoughts just after the episode, and indirectly decreased the present sense of unintegration of thoughts by meaning-making. Moreover, although recurrent thinking promoted the current sense of unintegration of thoughts, it also provided meaning.

1983-10-01

The need for collection of reliability, maintainability, and availability data adds a new dimension to the data acquisition requirements of equipment development tests. This report describes the reliability and maintainability data that are considered necessary to ensure that sufficient and high quality data exist for a comprehensive, quantitative evaluation of equipment and system availability. These necessary data are presented as a set of data collection forms. Three data acquisition forms are discussed: an inventory and technical data form, which is filed by the design engineer when the design is finished or the equipment is received; an event report form, which is completed by the senior test operator at each shutdown; and a maintainability report, which is a collaborative effort between senior operators and lead engineers and is completed on restart. In addition, elements of a reliability, maintainability evaluation program are described. Emphasis is placed on the role of data, its storage, and use in such a program

Challenges of designing fusion reactors for remote maintainability

International Nuclear Information System (INIS)

Mason, L.S.

1981-01-01

One of the major problems faced by the fusion community is the development of the high level of reliability required to assure that fusion will be a viable commercial power source. Much of the responsibility for solving this problem falls directly on the designer in developing concepts that have a high level of maintainability. The problems are both near-term, in developing maintainability for next generation engineering oriented reactors; and long range, in developing full maintainability for the more commercial concepts with their required high level of on-line time. The near-time challenge will include development of unqiue design concepts to perform inspection, maintenance, replacement, and testing under the stringent conditions imposed by the next generation engineering oriented machines. The long range challenge will focus on basic design concepts that will enable the full mainatability required by commerical fusion

Water quality maintaining device of power plant

International Nuclear Information System (INIS)

Kobayashi, Minoru; Inami, Ichiro.

1994-01-01

The device of the present invention reduces the amount of leaching materials of ion exchange resins from a water processing system of a BWR tyep plant, improves the water quality of reactor water to maintain the water at high purity. That is, steams used for power generation are condensated in a condensate system. A condensate filter and a condensate desalter for cleaning the condensates are disposed. A resin storage hopper is disposed for supplying the ion exchange resins to the water processing system. A device for supplying a nitrogen gas or an inert gas is disposed in the hopper. With such a constitution, the ion exchange resins in the water processing system are maintained in a nitrogen gas or inert gas atmosphere or at a low dissolved oxygen level in an operation stage in the power plant. Accordingly, degradation of the ion exchange resins in the water processing system is suppressed and the amount of the leaching material from the resins is reduced. As a result, the amount of the resins leached into the reactor is reduced, so that the reactor water quality can be maintained at high purity. (I.S.)

2013-04-01

Methadone-maintained persons are at increased risk for many physical and mental health disorders compared to the general population. Increased physical activity could offset these risks. We assessed physical activity level, and perceived benefits and barriers to exercise in a group of 305 methadone-maintained smokers. Mean participant age was 39.9 years, 50.2% were male, 79.7% were non-Hispanic White, and mean body mass index was 29.8. Nearly 45% endorsed fair or poor physical health. Although participants perceived many benefits of exercise and few barriers, only 38% of participants met weekly recommendations for physical activity, and nearly 25% reported no physical activity. Those who met recommended guidelines were significantly more likely to endorse relapse prevention as a benefit of exercise. Motivating MMT patients to increase physical activity could have important physical, mental health, and drug treatment benefits. Copyright © 2013 Elsevier Inc. All rights reserved.

A prescription for health: a primary care based intervention to maintain the non-smoking status of young people

Science.gov (United States)

Fidler, W.; Lambert, T.

2001-01-01

OBJECTIVES—To evaluate the effectiveness of primary health care teams in maintaining a group of young people aged 10-15 years as non-smokers.
DESIGN—Randomised controlled trial using postal questionnaires.
SETTING—Oxfordshire, UK.
SUBJECTS—2942 young people who were initially self declared non-smokers.
INTERVENTION—Information about smoking, sent under signature of the subject's general practitioner, certificates and posters intended to reinforce non-smoking behaviour.
MAIN OUTCOME MEASURES—Changes in smoking behaviour, attitudes measured after one year.
RESULTS—After a year, smoking uptake was 7.8% in the control group compared with 5.1% in the intervention group (odds ratio (OR) 1.6, 95% confidence interval (CI) 1.1 to 2.2). Among boys the corresponding results were 5.2% and 2.4% (OR 2.3, 95% CI 1.2 to 4.6), and among girls 10.0% and 7.5% (OR 1.4, 95% CI 0.9 to 2.1). Among boys aged 14-15 the uptake rate was 12.8% in the control group compared with 5.4% in the intervention group. However, among girls of the same age the intervention was less effective, with smoking uptake of 15.1% in the control group and 12.8% in the intervention group. The intervention was more effective among young people whose initial attitudes identified them as definite non-smokers than those who were potential smokers.
CONCLUSIONS—The intervention substantially reduced smoking uptake among the young people, particularly boys. Primary health care teams can play an important role in maintaining the non-smoking status of their young patients. Confidential postal contact from the doctor direct to the young person at home is influential and cost-effective.

Merging building maintainability and sustainability assessment: A multicriteria decision making approach

Science.gov (United States)

Asmone, A. S.; Chew, M. Y. L.

2018-02-01

Accurately predicting maintainability has been a challenge due to the complex nature of buildings, yet it is an important research area with a rising necessity. This paper explores the use of multicriteria decision making approach for merging maintainability and sustainability elements into building grading systems to attain long-term sustainability in the building industry. The paper conducts a systematic literature review on multicriteria decision analysis approach and builds on the existing knowledge of maintainability to achieve this. A conceptual framework is developed to bridge the gap between building operations and maintenance with green facilities management by forecasting green maintainability at the design stage.

The Power of Affirming Group Values: Group Affirmation Buffers the Self-Esteem of Women Exposed to Blatant Sexism.

Spencer-Rodgers, Julie; Major, Brenda; Forster, Daniel; Peng, Kaiping

2016-01-01

Extending the group affirmation literature to the domain of prejudice, this study investigated whether group affirmation buffers the self-esteem of women exposed to blatant sexism. In accordance with Self-Affirmation Theory (Steele, 1988) and group affirmation research (Sherman et al., 2007), we hypothesized that when one aspect of the collective self is threatened (gender identity), self-esteem can be maintained via the affirmation of an alternative aspect of the collective self. In a 2×2 between-participants design, female students were randomly assigned to read about discrimination directed toward women or a non-self-relevant disadvantaged group (the Inuit). All then participated in a (fictitious) second study, in which half completed a group affirmation manipulation (wrote about the top three values of a self-defining group) and half completed a control writing exercise. The self-esteem of women who were threatened by sexism, but group affirmed, was protected from the negative effects of perceiving sexism.

The communication of "pure" group-based anger reduces tendencies toward intergroup conflict because it increases out-group empathy.

de Vos, Bart; van Zomeren, Martijn; Gordijn, Ernestine H; Postmes, Tom

2013-08-01

The communication of group-based anger in intergroup conflict is often associated with destructive conflict behavior. However, we show that communicating group-based anger toward the out-group can evoke empathy and thus reduce intergroup conflict. This is because it stresses the value of maintaining a positive long-term intergroup relationship, thereby increasing understanding for the situation (in contrast to the communication of the closely related emotion of contempt). Three experiments demonstrate that the communication of group-based anger indeed reduces destructive conflict intentions compared with (a) a control condition (Experiments 1-2), (b) the communication of group-based contempt (Experiment 2), and (c) the communication of a combination of group-based anger and contempt (Experiments 2-3). Moreover, results from all three experiments reveal that empathy mediated the positive effect of communicating "pure" group-based anger. We discuss the implications of these findings for the theory and practice of communicating emotions in intergroup conflicts.

Group cohesion in foraging meerkats: follow the moving 'vocal hot spot'.

Science.gov (United States)

Gall, Gabriella E C; Manser, Marta B

2017-04-01

Group coordination, when 'on the move' or when visibility is low, is a challenge faced by many social living animals. While some animals manage to maintain cohesion solely through visual contact, the mechanism of group cohesion through other modes of communication, a necessity when visual contact is reduced, is not yet understood. Meerkats ( Suricata suricatta ), a small, social carnivore, forage as a cohesive group while moving continuously. While foraging, they frequently emit 'close calls', soft close-range contact calls. Variations in their call rates based on their local environment, coupled with individual movement, produce a dynamic acoustic landscape with a moving 'vocal hotspot' of the highest calling activity. We investigated whether meerkats follow such a vocal hotspot by playing back close calls of multiple individuals to foraging meerkats from the front and back edge of the group simultaneously. These two artificially induced vocal hotspots caused the group to spatially elongate and split into two subgroups. We conclude that meerkats use the emergent dynamic call pattern of the group to adjust their movement direction and maintain cohesion. Our study describes a highly flexible mechanism for the maintenance of group cohesion through vocal communication, for mobile species in habitats with low visibility and where movement decisions need to be adjusted continuously to changing environmental conditions.

Although an erythropoiesis-stimulating agent (ESA) is most frequently administered intravenously for treatment of anemia in patients with chronic kidney disease who are on dialysis, few studies have compared the efficacy of different intravenous (i.v.) dosing schedules. This multicenter, phase IIIb, open-label, controlled study randomized 289 stable hemodialysis patients to continue with conventional dosing of i.v. epoetin alfa or darbepoetin, or to switch to once-weekly i.v. epoetin alfa at the same cumulative weekly starting dose, to maintain hemoglobin levels at 11.0-13.0 g/dL, and within 1.0 g/dL of the baseline value. Hemoglobin levels and ESA doses were recorded every 4 weeks for 28 weeks. Hemoglobin levels fell significantly and ESA doses increased significantly between baseline and week 28 (mean of week 16-28 values) in the once-weekly epoetin alfa group, compared with the conventional treatment group (phemoglobin levels between the groups was 0.73 g/dL (greater than the threshold for therapeutic equivalence of 0.5 g/dL). The changes between groups from baseline was significant at all time points for hemoglobin levels (0.36, 0.46, 0.81, 0.87, 0.78, 0.62 and 0.49 g/dL) and from week 12 for ESA dose (718.5, 1,326.5, 1,732.0, 1,839.7 and 1,959.1 IU/week; p=0.005). Hemoglobin was maintained at the target level in 78% and 84% of patients on conventional dosing, and 67% and 64% of those on once-weekly epoetin alfa in the intention-to-treat (p=0.1) and per protocol (p=0.016) populations, respectively. This study did not show therapeutic equivalence of once-weekly i.v. epoetin alfa with conventional dosing regimens.

Business working group

International Nuclear Information System (INIS)

Doroshuk, B.W.

2000-01-01

The workshop of 26-27 june 2000, on nuclear power Plant LIfe Management (PLIM), also included working groups in which major issues facing PLIM activities for nuclear power plants were identified and discussed. The third group was on Business. The discussion concerned the following points: There are concerns about retaining experienced/trained personnel, and maintaining a good working relationship among them, as well as about the closure of research facilities, the reduction in staff numbers under increasing economic pressure and the lack of new nuclear power plant constructions. The marginal cost of producing electricity is lower for most existing nuclear power plants than for almost all other energy sources. Refurbishment costs are usually relatively small compared with new investments. The ongoing regulatory reform of the electricity market will bring increasing competition. Although PLIM has been carried out in many countries with favourable results, there are still uncertainties which affect business decisions regarding financial and market risks in PLIM activities. Recommendations were made. (author)

Methadone and buprenorphine are among the most widely employed pharmacological treatments currently available for opioid addiction. Cognitive effects of buprenorphine in abstinent heroin abusers are nevertheless far from being understood. Neuropsychological performance of 18 buprenorphine-maintained patients (BMP) was evaluated relative to that of 32 currently abstinent heroin abusers on naltrexone hydrochloride therapy (FHAN), and 34 non-drug dependent controls. The three groups were demographically balanced. Clinical groups reported histories of similar patterns of drug use and had increased periods of abstinence from any illicit substance use including heroin. The BMP group performed poorer than controls on the RAVLT (encoding and delayed recall of verbal information), CTT (conceptual flexibility, executive functions) and the RBANS figure copy (visual perception) and delayed recall of visual information. There were no significant differences in any of the cognitive measures between the BMP and FHAN groups or between the FHAN group and controls. Furthermore, the non-differing percentage of abnormal cases between the two patient groups led us to infer that treatment with either BPM or FHAN is not accompanied by qualitative differences in the cognitive profiles of these patients. Overall, results suggest that treatment with naltrexone in abstinent heroin abusers may result in less impairment of cognitive functions compared to treatment with buprenorphine. These findings are relevant for improved prognosis and treatment strategies in opioid dependence.

A reduction in tissue tolerance promotes the development of pressure ulcers (PUs) and incontinence-associated dermatitis (IAD). To determine the cost-effectiveness and efficacy of evidence-based (EB) nursing interventions on increasing tissue tolerance by maintaining tissue integrity. The study involved 154 patients in two intensive care units (77 patients, control group; 77 patients, intervention group). Data were collected using the following: patient characteristics form, Braden PU risk assessment scale, tissue integrity monitoring form, PU identification form, IAD and severity scale, and a cost table of the interventions. Patients in the intervention group were cared for by nurses trained in the use of the data collection tools and in EB practices to improve tissue tolerance. Routine nursing care was given to the patients in the control group. The researcher observed all patients in terms of tissue integrity and recorded the care-related costs. Deterioration of tissue integrity was observed in 18.2% patients in the intervention group compared to 54.5% in the control group (p cost to increase tissue tolerance prevention in the intervention and control groups was X¯ = $204.34 ± 41.07 and X¯ = $138.90 ± 1.70, respectively. It is recommended that EB policies and procedures are developed to improve tissue tolerance by maintaining tissue integrity. Although the cost of EB preventive initiatives is relatively high compared to those that are not EB, the former provide a significant reduction in the prevalence of tissue integrity deterioration. © 2017 Sigma Theta Tau International.

Challenges of designing fusion reactors for remote maintainability

International Nuclear Information System (INIS)

Masson, L.S.

1981-01-01

One of the major problems faced by the fusion community is the development of the high level of reliability required to assure that fusion will be a viable commercial power source. Much of the responsibility for solving this problem falls directly on the designer in developing concepts that have a high level of maintainability for the next generation engineering oriented reactors; and long range, in developing full maintainability for the more complicated commercial concepts with their required high level of on-line time. The near-term challenge will include development of unique design concepts to perform inspection, maintenance, replacement, and testing under the stringent conditions imposed by the next generation engineering oriented machines. The long range challenge will focus on basic design concepts that will enable the full maintainability required by commercial fusion. In addition to the purely technical challenges, the fusion community is also faced with the problem of developing programmatic means to assure that reactor maintenance issues are given proper and timely emphasis as the nuclear phase of fusion is approached

The importance of maintainability in maintenance cost management

1996-01-01

This paper provides specific examples and results from ongoing projects at Power Plants, and for offshore oil platforms. The paper describes the vital role maintainability has on plant availability. How the application of equipment maintainability principles, if addressed using state of the art computer tools and advanced business processes can bring annual return on investment results as high as 15 to 1. The maintenance process of today and for the future must provide for high plant availability at the lowest possible cost. The high cost of obtaining equipment reliability levels necessary to meet required availability demands has not proved to be sustainable. Therefore new business decision processes that address equipment failures as part of the maintenance process have been developed. Repair costs require that equipment failures be selective and controlled so that a high level of safety and plant availability is assurance. This can only be accomplished by the use of advanced computer tools in the hands of well trained maintenance-engineering specialist. The relationship between Reliability Centered Maintenance (RCM), Condition Directed Planned Maintenance (CDPM), and maintainability is also presented

Full Text Available The objectives of the present study are four-fold: (1 to identify the types of strategies to maintain proficiency used by teachers of English in Indonesia, (2 to know the intensity of use of the obtained strategy types, (3 to measure the inter-correlation in the use of the obtained strategy types, and (4 to investigate the effect of proficiency level on the use of maintaining strategies. The subjects were 93 teachers applying for S2 degree in 2010/2011 at the postgraduate program of the Islamic University of Malang. They were given two sets of instrument, a Likert-scale questionnaire of English proficiency maintaining strategies and a TOEFL test. Then, a factor analysis identified nine strategy categories, including language focusing, metacognitive and affective developing, reading and writing activating, language resource utilizing, cognitive processing, culture learning, social communicating, text analyzing, and radio listening strategies. These strategy types explained 63.84% of variances of maintaining strategies and they were used at high level of intensity. Moreover, the use of the nine strategy types were found to be inter-correlated with one another. Finally, no significant effect of proficiency level on strategy use was found, indicating that teachers with different level of proficiency reported using the same strategies of maintaining their proficiency.

The formalism of Lie groups

Energy Technology Data Exchange (ETDEWEB)

Salam, A. [Imperial College of Science and Technology, London (United Kingdom)

1963-01-15

Throughout the history of quantum theory, a battle has raged between the amateurs and professional group theorists. The amateurs have maintained that everything one needs in the theory of groups can be discovered by the light of nature provided one knows how to multiply two matrices. In support of this claim, they of course, justifiably, point to the successes of that prince of amateurs in this field, Dirac, particularly with the spinor representations of the Lorentz group. As an amateur myself, I strongly believe in the truth of the non-professionalist creed. I think perhaps there is not much one has to learn in the way of methodology from the group theorists except caution. But this does not mean one should not be aware of the riches which have been amassed over the course of years particularly in that most highly developed of all mathematical disciplines - the theory of Lie groups. My lectures then are an amateur's attempt to gather some of the fascinating results for compact simple Lie groups which are likely to be of physical interest. I shall state theorems; and with a physicist's typical unconcern rarely, if ever, shall I prove these. Throughout, the emphasis will be to show the close similarity of these general groups with that most familiar of all groups, the group of rotations in three dimensions.

Group size, grooming and fission in primates: a modeling approach based on group structure.

Science.gov (United States)

Sueur, Cédric; Deneubourg, Jean-Louis; Petit, Odile; Couzin, Iain D

2011-03-21

In social animals, fission is a common mode of group proliferation and dispersion and may be affected by genetic or other social factors. Sociality implies preserving relationships between group members. An increase in group size and/or in competition for food within the group can result in decrease certain social interactions between members, and the group may split irreversibly as a consequence. One individual may try to maintain bonds with a maximum of group members in order to keep group cohesion, i.e. proximity and stable relationships. However, this strategy needs time and time is often limited. In addition, previous studies have shown that whatever the group size, an individual interacts only with certain grooming partners. There, we develop a computational model to assess how dynamics of group cohesion are related to group size and to the structure of grooming relationships. Groups' sizes after simulated fission are compared to observed sizes of 40 groups of primates. Results showed that the relationship between grooming time and group size is dependent on how each individual attributes grooming time to its social partners, i.e. grooming a few number of preferred partners or grooming equally or not all partners. The number of partners seemed to be more important for the group cohesion than the grooming time itself. This structural constraint has important consequences on group sociality, as it gives the possibility of competition for grooming partners, attraction for high-ranking individuals as found in primates' groups. It could, however, also have implications when considering the cognitive capacities of primates. Copyright © 2010 Elsevier Ltd. All rights reserved.

Mehta, Ranjana K; Rhee, Joohyun

2017-07-01

Stress due to cognitive demands and fatigue have shown to impair motor performance in older adults; however, the effect of social stress and its influence on prefrontal cortex (PFC) functioning in older adults during upper extremity motor performance tasks is not known. The present study explored the after-effects of an acute social stress bout on neural strategies, measured using PFC and hand/arm muscle activation, and adopted by younger and older adults to maintain handgrip force control. Nine older [74.1 (6.5) years; three men, six women] and ten younger [24.2 (5.0) years, four men, six women] adults performed handgrip force control trials at 30% maximum voluntary contractions before and after the Trier Social Stress Test (TSST). PFC activity was measured using functional near infrared spectroscopy and muscle activity from the flexor and extensor carpi radialis (FCR/ECR) was measured using electromyography. In general, aging was associated with decreased force steadiness and force complexity with a concomitant increase in bilateral PFC activity. While motor performance remained comparable before and after the TSST stress session in both age groups, the associated neural strategies differed between groups. While the stress condition was associated with lower FCR and ECR activity in younger adults despite no change in the PFC activation, stress was associated with increases in FCR activity in older adults. This stress-related compensatory neural strategy of increasing hand/arm muscle activation, potentially via the additional recruitment of the stress-motor neural circuitry, may have played a role in maintaining motor performance in older adults.

Full Text Available Abstract Background There is little qualitative insight into how persons with chronic Whiplash-Associated Disorder cope on a day to day basis. This study seeks to identify the symptoms persons with Whiplash-Associated Disorder describe as dominating and explore their self-initiated coping strategies. Methods Qualitative study using focus groups interviews. Fourteen Norwegian men and women with Whiplash-Associated Disorder (I or II were recruited to participate in two focus groups. Data were analyzed according to a phenomenological approach, and discussed within the model of Cognitive Activation Theory of Stress (CATS. Results Participants reported neck and head pain, sensory hypersensitivity, and cognitive dysfunction following their whiplash injury. Based on the intensity of symptoms, participants divided everyday life into good and bad periods. In good periods the symptoms were perceived as manageable. In bad periods the symptoms intensified and took control of the individual. Participants expressed a constant notion of trying to balance their three main coping strategies; rest, exercise, and social withdrawal. In good periods participants experienced coping by expecting good results from the strategies they used. In bad periods they experienced no or negative relationships between their behavioral strategies and their complaints. Conclusions Neck and head pain, sensory hypersensitivity, and cognitive dysfunction were reported as participants' main complaints. A constant notion of balancing between their three main coping strategies; rest, exercise, and social withdrawal, was described.

Chewing Maintains Hippocampus-Dependent Cognitive Function.

Mastication (chewing) is important not only for food intake, but also for preserving and promoting the general health. Recent studies have showed that mastication helps to maintain cognitive functions in the hippocampus, a central nervous system region vital for spatial memory and learning. The purpose of this paper is to review the recent progress of the association between mastication and the hippocampus-dependent cognitive function. There are multiple neural circuits connecting the masticatory organs and the hippocampus. Both animal and human studies indicated that cognitive functioning is influenced by mastication. Masticatory dysfunction is associated with the hippocampal morphological impairments and the hippocampus-dependent spatial memory deficits, especially in elderly. Mastication is an effective behavior for maintaining the hippocampus-dependent cognitive performance, which deteriorates with aging. Therefore, chewing may represent a useful approach in preserving and promoting the hippocampus-dependent cognitive function in older people. We also discussed several possible mechanisms involved in the interaction between mastication and the hippocampal neurogenesis and the future directions for this unique fascinating research.

Maintaining heterokaryosis in pseudo-homothallic fungi.

Among all the strategies displayed by fungi to reproduce and propagate, some species have adopted a peculiar behavior called pseudo-homothallism. Pseudo-homothallic fungi are true heterothallics, i.e., they need 2 genetically-compatible partners to mate, but they produce self-fertile mycelium in which the 2 different nuclei carrying the compatible mating types are present. This lifestyle not only enables the fungus to reproduce without finding a compatible partner, but also to cross with any mate it may encounter. However, to be fully functional, pseudo-homothallism requires maintaining heterokaryosis at every stage of the life cycle. We recently showed that neither the structure of the mating-type locus nor hybrid-enhancing effect due to the presence of the 2 mating types accounts for the maintenance of heterokaryosis in the pseudo-homothallic fungus P. anserina. In this addendum, we summarize the mechanisms creating heterokaryosis in P. anserina and 2 other well-known pseudo-homothallic fungi, Neurospora tetrasperma and Agaricus bisporus. We also discuss mechanisms potentially involved in maintaining heterokaryosis in these 3 species.

To evaluate the effects of testosterone (T) on the maintenance of corpus cavernosum (CC) structure and apoptosis. Animals were divided into three groups: sham operation group ( n  = 8) underwent sham operation; Orchiectomized (Orchiec)+ oily vehicle group ( n  = 8) underwent bilateral orchiectomy and received a single dose of oily vehicle by intramuscular injection (i.m.) 30 days after orchiectomy; and Orchiec + T group ( n  = 8) underwent bilateral orchiectomy and received a single dose of T undecanoate 100 mg/kg i.m. 30 days after the surgery. Animals were euthanized 60 days after the beginning of the experiment with an anesthetic overdose of ketamine and xylazine. Blood samples and penile tissue were collected on euthanasia. Azan's trichrome staining was used to evaluate smooth muscle, Weigert's Fucsin-Resorcin staining was used to evaluate elastic fibers and Picrosirius red staining was used to evaluate collagen. Apoptosis was evaluated using TUNEL technique. T levels decreased in Orchiec + oily vehicle when compared to sham operation and Orchiec + T groups ( p  space ( p  = 0.207), elastic fibers ( p  = 0.849), collagen ( p  = 0.216) and in apoptosis ( p  = 0.095). Normal testosterone levels maintain CC smooth muscle content and do not influence elastic fibers, collagen content and apoptotic index. Further studies should be performed in order to investigate the mechanisms by which androgen mediates its effects on CC structure.

Gestures maintain spatial imagery.

Wesp, R; Hesse, J; Keutmann, D; Wheaton, K

2001-01-01

Recent theories suggest alternatives to the commonly held belief that the sole role of gestures is to communicate meaning directly to listeners. Evidence suggests that gestures may serve a cognitive function for speakers, possibly acting as lexical primes. We observed that participants gestured more often when describing a picture from memory than when the picture was present and that gestures were not influenced by manipulating eye contact of a listener. We argue that spatial imagery serves a short-term memory function during lexical search and that gestures may help maintain spatial images. When spatial imagery is not necessary, as in conditions of direct visual stimulation, reliance on gestures is reduced or eliminated.

We have engineered magnetism in graphene oxide. Our approach transforms graphene into a magnetic insulator while maintaining graphene's structure. Fourier transform infrared spectroscopy spectra reveal that graphene oxide has various chemical groups (including epoxy, ketone, hydroxyl, and C-O groups) on its surface. Destroying the epoxy group with heat treatment or chemical treatment diminishes magnetism in the material. Local density approximation calculation results well reproduce the magnetic moments obtained from experiments, and these results indicate that the unpaired spin induced by the presence of epoxy groups is the origin of the magnetism. The calculation results also explain the magnetic properties, which are generated by the interaction between separated magnetic regions and domains. Our results demonstrate tunable magnetism in graphene oxide based on controlling the epoxy group with heat or chemical treatment.

Ingestion of high-fructose corn syrup (HFCS) is associated with the risk of both diabetes and obesity. Rare sugar syrup (RSS) has been developed by alkaline isomerization of HFCS and has anti-obesity and anti-diabetic effects. However, the influence of RSS on glucose metabolism has not been explored. We investigated whether long-term administration of RSS maintains glucose tolerance and whether the underlying mechanism involves hepatic glucokinase translocation. Wistar rats were administered water, RSS, or HFCS in drinking water for 10 weeks and then evaluated for glucose tolerance, insulin tolerance, liver glycogen content, and subcellular distribution of liver glucokinase. RSS significantly suppressed body weight gain and abdominal fat mass (p glucose tolerance test revealed significantly higher blood glucose levels in the HFCS group compared to the water group, whereas the RSS group had significantly lower blood glucose levels from 90 to 180 min (p water group (p glucose loading, the nuclear export of glucokinase was significantly increased in the RSS group compared to the water group. These results imply that RSS maintains glucose tolerance and insulin sensitivity, at least partly, by enhancing nuclear export of hepatic glucokinase.

Seniors' self-preservation by maintaining established self and defying deterioration - A grounded theory.

Eriksson, Jeanette Källstrand; Hildingh, Cathrine; Buer, Nina; Thulesius, Hans

2016-01-01

The purpose of this classic grounded theory study was to understand how seniors who are living independently resolve issues influenced by visual impairment and high fall risk. We interviewed and observed 13 seniors with visual impairment in their homes. We also interviewed six visual instructors with experience from many hundreds of relevant incidents from the same group of seniors. We found that the seniors are resolving their main concern of "remaining themselves as who they used to be" by self-preservation. Within this category, the strategies maintaining the established self and defying deterioration emerged as the most prominent in our data. The theme maintaining the established self is mostly guided by change inertia and includes living the past (retaining past activities, reminiscing, and keeping the home intact) and facading (hiding impairment, leading to avoidance of becoming a burden and to risk juggling). Defying deterioration is a proactive scheme and involves moving (by exercising, adapting activities, using walking aids, driving), adapting (by finding new ways), and networking by sustaining old support networks or finding new networks. Self-preservation is generic human behavior and modifying this theory to other fields may therefore be worthwhile. In addition, health care providers may have use for the theory in fall preventive planning.

Full Text Available Premature loss could cause a problem with the tooth arrangement or the dental arch size. A space left by the primary tooth loss could cause migration of the adjacent teeth. As a result, space will be narrowed and undermined the eruption of the permanent teeth. The success of the space maintainer or space regainer usage due to the premature loss marked by space for the replacement of the permanent teeth. The purpose of this research was to evaluate the compliance of children in wearing a space maintainer or space regainer after insertion at Pedodontics Installation of Faculty of Dentistry Universitas Padjadjaran Dental Hospital, Bandung, Indonesia. The research method was descriptive survey technique. The sample consisted of 30 patients selected using the total sampling technique. Data were obtained with a questionnaire and statistically analyzed. The results showed that majority of the children uses the removable space maintainer or the space regainer daily was only about 23,3% overall. Most of the children only use the removable space maintainer or the space regainer for sometimes. The research concluded that the low rate of pedodontic patients compliance at Pedodontics Installation of Faculty of Dentistry Universitas Padjadjaran Dental Hospital in the usage of the removable space maintainer or the space regainer was usually caused by pain or discomfort. This fact was evidence of a low awareness of parents in preventing malocclusion to their children.

Jacoby, Dana L; Maller, Bruce S; Peltier, Lisa R

2014-10-01

Market forces in health care have created substantial regulatory, legislative, and reimbursement changes that have had a significant impact on urology group practices. To maintain viability, many urology groups have merged into larger integrated entities. Although group operations vary considerably, the majority of groups have struggled with the development of a strong culture, effective decision-making, and consensus-building around shared resources, income, and expense. Creating a sustainable business model requires urology group leaders to allocate appropriate time and resources to address these issues in a proactive manner. This article outlines collaboration strategies for creating an effective culture, governance, and leadership, and provides practical suggestions for optimizing the performance of the urology group practice.

Salivary habituation to food stimuli in successful weight loss maintainers, obese and normal-weight adults

Science.gov (United States)

Bond, DS; Raynor, HA; McCaffery, JM; Wing, RR

2017-01-01

Objective Research shows that slower habituation of salivary responses to food stimuli is related to greater energy intake and that obese (Ob) individuals habituate slower than those of normal weight (NW). No study has examined habituation rates in weight loss maintainers (WLMs) who have reduced from obese to normal weight, relative to those who are Ob or NW. Design Salivation to two baseline water trials and 10 lemon-flavored lollipop trials were studied in 14 WLMs, 15 Ob and 18 NW individuals comparable in age, gender and ethnicity. Linear mixed models were used to compare WLMs with Ob and NW groups. Results Salivation in the WLM and NW groups decreased significantly (for both P <0.005) across trials, indicative of habituation. Salivary responses in the Ob group did not habituate (P=0.46). When compared with Ob group, WLMs showed a quicker reduction in salivation (P<0.05). WLM and NW groups did not differ in habituation rate (P=0.49). Conclusions WLMs have habituation rates that are comparable to NW individuals without previous history of obesity, and show quicker habituation than those who are currently obese. These results suggest that physiological responses to food may ‘normalize’ with successful weight loss maintenance. PMID:20010900

Paraguay has registered no human cases of rabies since 2004, and the last case in dogs, reported in 2009, was due to a variant maintained in the common vampire bat "Desmodus rotundus". In 2014, a dog was diagnosed as positive for rabies with aggression towards a boy and all required measures of control were successfully adopted. Epidemiological investigation revealed that the dog was not vaccinated and had been attacked by a crab-eating fox, "zorro" (Cerdocyon thous). The sample was diagnosed by the Official Veterinary Service of the Country and sent to the Center on Rabies Research from the University of São Paulo, Brazil, for antigenic and genetic characterization. A second sample from a dog positive for rabies in the same region in 2015 and 11 samples from a rabies outbreak from Asuncion in 1996 were also characterized. The antigenic profile of the samples, AgV2, was compatible with one of the variants maintained by dogs in Latin America. In genetic characterization, the samples segregated in the canine (domestic and wild species)-related group in an independent subgroup that also included samples from Argentina. These results and the epidemiology of the case indicate that even with the control of rabies in domestic animals, the virus can still circulate in wildlife and may be transmitted to domestic animals and humans, demonstrating the importance of continuous and improved surveillance and control of rabies, including in wild species, to prevent outbreaks in controlled areas. © 2017 Blackwell Verlag GmbH.

Vestibular feedback maintains reaching accuracy during body movement

Science.gov (United States)

Reynolds, Raymond F.

2016-01-01

Key points Reaching movements can be perturbed by vestibular input, but the function of this response is unclear.Here, we applied galvanic vestibular stimulation concurrently with real body movement while subjects maintained arm position either fixed in space or fixed with respect to their body.During the fixed‐in‐space conditions, galvanic vestibular stimulation caused large changes in arm trajectory consistent with a compensatory response to maintain upper‐limb accuracy in the face of body movement.Galvanic vestibular stimulation responses were absent during the body‐fixed task, demonstrating task dependency in vestibular control of the upper limb.The results suggest that the function of vestibular‐evoked arm movements is to maintain the accuracy of the upper limb during unpredictable body movement, but only when reaching in an earth‐fixed reference frame. Abstract When using our arms to interact with the world, unintended body motion can introduce movement error. A mechanism that could detect and compensate for such motion would be beneficial. Observations of arm movements evoked by vestibular stimulation provide some support for this mechanism. However, the physiological function underlying these artificially evoked movements is unclear from previous research. For such a mechanism to be functional, it should operate only when the arm is being controlled in an earth‐fixed rather than a body‐fixed reference frame. In the latter case, compensation would be unnecessary and even deleterious. To test this hypothesis, subjects were gently rotated in a chair while being asked to maintain their outstretched arm pointing towards either earth‐fixed or body‐fixed memorized targets. Galvanic vestibular stimulation was applied concurrently during rotation to isolate the influence of vestibular input, uncontaminated by inertial factors. During the earth‐fixed task, galvanic vestibular stimulation produced large polarity‐dependent corrections in arm

Professionals with hearing loss: maintaining that competitive edge.

Tye-Murray, Nancy; Spry, Jacqueline L; Mauzé, Elizabeth

2009-08-01

The goals of this investigation were to gauge how hearing loss affects the self-perceived job performance and psycho-emotional status of professionals in the workforce and to develop a profile of their aural rehabilitation needs. Forty-eight participants who had at least a high school education and who hold salaried positions participated in one of seven focus groups. Participants first answered questions about a hypothetical executive who had hearing loss and considered how she might react to various communication issues. They then addressed questions about their own work-related predicaments. The sessions were audiovideo recorded and later transcribed for analysis. Unlike workers who have occupational hearing loss, the professionals in this investigation seem not to experience an inordinate degree of stigmatization in their workplaces, although most believe that hearing loss has negatively affected their job performance. Some of the participants believe that they have lost their "competitive edge," and some believe that they have been denied promotions because of hearing loss. However, most report that they have overcome their hearing-related difficulties by various means, and many have developed a determination and stamina to remain active in the workforce. The majority of the participants seemed to be unfamiliar with the Americans with Disability Act, Public Law 101-336. The overriding theme to emerge is that professionals desire to maintain their competency to perform their jobs and will do what they have to do to "get the job done." The situations of professionals who have hearing loss can be modeled, with a central theme of maintaining job competency or a competitive edge. It is hypothesized that five factors affect professionals' abilities to continue their optimal work performance in the face of hearing loss: (a) self-concept and sense of internal locus of control, (b) use of hearing assistive technology, (c) supervisor's and co-workers' perceptions and

The aim of this study was to explore views, experiences und perspectives of German GPs related to current out-of-hours service provision covering both urban and rural settings. In the context of the international project EurOOHnet (European Research Network for Out-of-Hours Primary Health Care) the German members (of EurOOHnet) developed a questionnaire about organisational structures, infrastructure requirements and the procedures of information flow between regular care and out-of-hours care in 2011. This questionnaire was adopted in every participating country. A comprehensive postal questionnaire was sent to 410 feneral practice cooperatives in Germany. Qualitative content analysis and an inductive reasoning process, supported by the use of Atlas.ti, were used to identify key themes from responses to open-ended questions in the survey. Results were grouped into 3 overarching categories and each of these were grouped into 3 sub-categories. The questionnaire response rate was 44% (181/410). The analysis identified organisational issues (e. g., financing) and infrastructure barriers (e. g., lack of motivated GPs for out-of-hours care) as key themes. Significantly, different priorities between rural and urban GPs were identified. In particular, rural GPs highlighted shortages of GPs and distance between the GP practice and patients' residence as concerning factors impacting on out-of-hours care. Based on reported views from survey respondents, urban and rural primary care service needs vary significantly and, therefore, different solutions are needed to improve out-of-hours primary care and optimise service quality. © Georg Thieme Verlag KG Stuttgart · New York.

Given the widespread use of water immersion during recovery from exercise, we aimed to investigate the effect of contrast water immersion on recovery of sprint cycling performance, HR and, blood lactate. Two groups completed high-intensity sprint exercise before and after a 30-min randomized recovery. The Wingate group (n = 8) performed 3 × 30-s Wingate tests (4-min rest periods). The repeated intermittent sprint group (n = 8) cycled for alternating 30-s periods at 40% of predetermined maximum power and 120% maximum power, until exhaustion. Both groups completed three trials using a different recovery treatment for each trial (balanced randomized application). Recovery treatments were passive rest, 1:1 contrast water immersion (2.5 min of cold (8°C) to 2.5 min of hot (40°C)), and 1:4 contrast water immersion (1 min of cold to 4 min of hot). Blood lactate and HR were recorded throughout, and peak power and total work for pre- and postrecovery Wingate performance and exercise time and total work for repeated sprinting were recorded. Recovery of Wingate peak power was 8% greater after 1:4 contrast water immersion than after passive rest, whereas both contrast water immersion ratios provided a greater recovery of exercise time (∼ 10%) and total work (∼ 14%) for repeated sprinting than for passive rest. Blood lactate was similar between trials. Compared with passive rest, HR initially declined more slowly during contrast water immersion but increased with each transition to a cold immersion phase. These data support contrast water immersion being effective in maintaining performance during a short-term recovery from sprint exercise. This effect needs further investigation but is likely explained by cardiovascular mechanisms, shown here by an elevation in HR upon each cold immersion.

2014-08-01

Individuals with knee OA often exhibit greater co-contraction of antagonistic muscle groups surrounding the affected joint which may lead to increases in dynamic joint stiffness. These detrimental changes in the symptomatic limb may also exist in the contralateral limb, thus contributing to its risk of developing knee osteoarthritis. The purpose of this study is to investigate the interlimb symmetry of dynamic knee joint stiffness and muscular co-contraction in knee osteoarthritis. Muscular co-contraction and dynamic knee joint stiffness were assessed in 17 subjects with mild to moderate unilateral medial compartment knee osteoarthritis and 17 healthy control subjects while walking at a controlled speed (1.0m/s). Paired and independent t-tests determined whether significant differences exist between groups (pknees compared to the healthy group (p=0.051). Subjects with mild to moderate knee osteoarthritis maintain symmetric control strategies during gait. Copyright © 2014 Elsevier Ltd. All rights reserved.

Individuals with developmental disabilities may engage in automatically reinforced behaviors that may interfere with learning opportunities. Manipulation of motivating operations has been shown to reduce automatically maintained behavior in some individuals. Considering behavioral indicators of satiation may assist in identifying the point at which an abolishing operation has begun to effect behavior. The purpose of this study was to evaluate the effects of pre-session satiation of automatic reinforcement on subsequent levels of stereotypy and activity engagement during group activities for three males ages 5 to 13 years with developmental disabilities. Following functional analyses with analogue conditions, an alternating treatment design compared a pre-session access to stereotypy condition with a no-pre-session access condition prior to group activity sessions. Results indicated that pre-session satiation of the putative reinforcer produced by stereotypy was effective in decreasing stereotypy and increasing activity engagement during subsequent group activities for all participants. These findings add to the literature supporting the effectiveness of abolishing operations to decrease automatically maintained stereotypy. © The Author(s) 2013.

All hematopoiesis cells develop from multipotent progenitor cells. Hematopoietic stem cells (HSC) have the ability to develop into all blood lineages but also maintain their stemness. Different molecular mechanisms have been identified that are crucial for regulating quiescence and self-renewal to maintain the stem cell pool and for inducing proliferation and lineage differentiation. The stem cell niche provides the microenvironment to keep HSC in a quiescent state. Furthermore, several trans...

Seniors’ self-preservation by maintaining established self and defying deterioration – A grounded theory

Science.gov (United States)

Eriksson, Jeanette Källstrand; Hildingh, Cathrine; Buer, Nina; Thulesius, Hans

2016-01-01

The purpose of this classic grounded theory study was to understand how seniors who are living independently resolve issues influenced by visual impairment and high fall risk. We interviewed and observed 13 seniors with visual impairment in their homes. We also interviewed six visual instructors with experience from many hundreds of relevant incidents from the same group of seniors. We found that the seniors are resolving their main concern of “remaining themselves as who they used to be” by self-preservation. Within this category, the strategies maintaining the established self and defying deterioration emerged as the most prominent in our data. The theme maintaining the established self is mostly guided by change inertia and includes living the past (retaining past activities, reminiscing, and keeping the home intact) and facading (hiding impairment, leading to avoidance of becoming a burden and to risk juggling). Defying deterioration is a proactive scheme and involves moving (by exercising, adapting activities, using walking aids, driving), adapting (by finding new ways), and networking by sustaining old support networks or finding new networks. Self-preservation is generic human behavior and modifying this theory to other fields may therefore be worthwhile. In addition, health care providers may have use for the theory in fall preventive planning. PMID:27172511

A practical method for the maintainability assessment in industrial devices using indicators and specific attributes

International Nuclear Information System (INIS)

Moreu De Leon, Pedro; González-Prida Díaz, Vicente; Barberá Martínez, Luis; Crespo Márquez, Adolfo

2012-01-01

The objective of this paper is to describe a procedure to obtain maintainability indicators for industrial devices. This analysis can be helpful, among other cases, to compare systems, to achieve a better design regarding maintainability requirements, to improve this maintainability under specific industrial environment and to foresee maintainability problems due to eventual changes in a device operation conditions. This maintainability assessment can be carried out at any stage of the industrial asset life cycle. With this purpose, this work first introduces the notion of maintainability and the implementation of assessment indicators, including some important requirements to perform that. Then, a brief literature review is presented, including the definition of the main concepts, which are later used in the paper. After studying the maintenance levels and the maintainability attributes, both terms are linked, leading all this analysis to the assessment of the maintainability indicators. It follows a discussion about the information obtained through the maintainability assessment process and its computation into several maintainability indicators. The paper includes a case study, which implements the defined assessment into a practical scenario. Finally, the work concludes summarizing the more significant aspects and suggesting future researches.

Complex Cooperative Strategies in Group-Territorial African Lions

Science.gov (United States)

Heinsohn, Robert; Packer, Craig

1995-09-01

Female lions (Panthera leo) showed persistent individual differences in the extent to which they participated in group-territorial conflict. When intergroup encounters were simulated by playback of aggressive vocalizations, some individuals consistently led the approach to the recorded intruder, whereas others lagged behind and avoided the risks of fighting. The lead females recognized that certain companions were laggards but failed to punish them, which suggests that cooperation is not maintained by reciprocity. Modification of the "odds" in these encounters revealed that some females joined the group response when they were most needed, whereas other lagged even farther behind. The complexity of these responses emphasizes the great diversity of individual behavior in this species and the inadequacy of current theory to explain cooperation in large groups.

Neuronal cell identity is established during development and must be maintained throughout an animal's life (Fishell G, Heintz N. Neuron 80: 602-612, 2013). Transcription factors critical for establishing neuronal identity can be required for maintaining it (Deneris ES, Hobert O. Nat Neurosci 17: 899-907, 2014). Posttranscriptional regulation also plays an important role in neuronal differentiation (Bian S, Sun T. Mol Neurobiol 44: 359-373, 2011), but its role in maintaining cell identity is less established. To better understand how posttranscriptional regulation might contribute to cell identity, we examined the proprioceptive neurons in the dorsal root ganglion (DRG), a highly specialized sensory neuron class, with well-established properties that distinguish them from other neurons in the ganglion. By conditionally ablating Dicer in mice, using parvalbumin (Pvalb)-driven Cre recombinase, we impaired posttranscriptional regulation in the proprioceptive sensory neuron population. Knockout (KO) animals display a progressive form of ataxia at the beginning of the fourth postnatal week that is accompanied by a cell death within the DRG. Before cell loss, expression profiling shows a reduction of proprioceptor specific genes and an increased expression of nonproprioceptive genes normally enriched in other ganglion neurons. Furthermore, although central connections of these neurons are intact, the peripheral connections to the muscle are functionally impaired. Posttranscriptional regulation is therefore necessary to retain the transcriptional identity and support functional specialization of the proprioceptive sensory neurons. NEW & NOTEWORTHY We have demonstrated that selectively impairing Dicer in parvalbumin-positive neurons, which include the proprioceptors, triggers behavioral changes, a lack of muscle connectivity, and a loss of transcriptional identity as observed through RNA sequencing. These results suggest that Dicer and, most likely by extension, micro

Prefrontal Neuronal Excitability Maintains Cocaine-Associated Memory During Retrieval

Directory of Open Access Journals (Sweden)

James M. Otis

2018-06-01

Full Text Available Presentation of drug-associated cues provokes craving and drug seeking, and elimination of these associative memories would facilitate recovery from addiction. Emotionally salient memories are maintained during retrieval, as particular pharmacologic or optogenetic perturbations of memory circuits during retrieval, but not after, can induce long-lasting memory impairments. For example, in rats, inhibition of noradrenergic beta-receptors, which control intrinsic neuronal excitability, in the prelimbic medial prefrontal cortex (PL-mPFC can cause long-term memory impairments that prevent subsequent cocaine-induced reinstatement. The physiologic mechanisms that allow noradrenergic signaling to maintain drug-associated memories during retrieval, however, are unclear. Here we combine patch-clamp electrophysiology ex vivo and behavioral neuropharmacology in vivo to evaluate the mechanisms that maintain drug-associated memory during retrieval in rats. Consistent with previous studies, we find that cocaine experience increases the intrinsic excitability of pyramidal neurons in PL-mPFC. In addition, we now find that this intrinsic plasticity positively predicts the retrieval of a cocaine-induced conditioned place preference (CPP memory, suggesting that such plasticity may contribute to drug-associated memory retrieval. In further support of this, we find that pharmacological blockade of a cAMP-dependent signaling cascade, which allows noradrenergic signaling to elevate neuronal excitability, is required for memory maintenance during retrieval. Thus, inhibition of PL-mPFC neuronal excitability during memory retrieval not only leads to long-term deficits in the memory, but this memory deficit provides protection against subsequent cocaine-induced reinstatement. These data reveal that PL-mPFC intrinsic neuronal excitability maintains a cocaine-associated memory during retrieval and suggest a unique mechanism whereby drug-associated memories could be targeted

Creatine, a nitrogenous organic acid, replenishes cytoplasmic ATP at the expense of mitochondrial ATP via the phosphocreatine shuttle. Creatine levels are maintained by diet and endogenous synthesis from arginine and glycine. Glycine amidinotransferase (GATM) catalyzes the rate-limiting step of creatine biosynthesis: the transfer of an amidino group from arginine to glycine to form ornithine and guanidinoacetate. We screened 36,530 third-generation germline mutant mice derived from N -ethyl- N -nitrosourea-mutagenized grandsires for intestinal homeostasis abnormalities after oral administration of dextran sodium sulfate (DSS). Among 27 colitis susceptibility phenotypes identified and mapped, one was strongly correlated with a missense mutation in Gatm in a recessive model of inheritance, and causation was confirmed by CRISPR/Cas9 gene targeting. Supplementation of homozygous Gatm mutants with exogenous creatine ameliorated the colitis phenotype. CRISPR/Cas9-targeted ( Gatm c/c ) mice displayed a normal peripheral immune response and immune cell homeostasis. However, the intestinal epithelium of the Gatm c/c mice displayed increased cell death and decreased proliferation during DSS treatment. In addition, Gatm c/c colonocytes showed increased metabolic stress in response to DSS with higher levels of phospho-AMPK and lower levels of phosphorylation of mammalian target of rapamycin (phospho-mTOR). These findings establish an in vivo requirement for rapid replenishment of cytoplasmic ATP within colonic epithelial cells in the maintenance of the mucosal barrier after injury.

Improved reliability, maintainability and safety through elastomer upgrading

International Nuclear Information System (INIS)

Wensel, R.; Wittich, K.C.

1995-01-01

Equipment in nuclear plants has historically contained whatever elastomer each component supplier traditionally used for corresponding non-nuclear service. The resulting proliferation of elastomer compounds, many of which are far from optimal for the service conditions (e.g., pressure, temperature, radiation, etc.), has multiplied the costs to provide station reliability, maintainability and safety. Cost-effective improvements are being achieved in CANDU plants by upgrading and standardizing on a handful of high performing elastomer compounds. These upgraded materials offer significant gains in service life over the materials they replace (often by factors of 2 or more). This rationalization of elastomer compounds also facilitates the EQ process for safety-related equipment. Detailed test data on aging is currently being generated for these specific elastomers, encompassing the conditions and media (air, water, oil) common in CANDU service. Two key elements characterize this testing. First, each result is specific to the compound used in the test, and second, it is specific to the tested failure mode (e.g., compression set, extrusion, fracture, etc.). Having fewer, but more thoroughly tested compounds, avoids the penalty (associated with poorly characterized materials) of having to replace parts prematurely because of conservatism, while maintaining safe, reliable service. This paper provides an overview of this approach covering: the benefits of compound rationalization; and the how and why of establishing relevant failure criteria; appropriate quality assurance to maintain EQ; procurement, storage and handling guidelines; and monitoring and predicting in-service degradation.

Doses to worker groups in the nuclear industry

Khan, T.; Baum, J.W.

1992-01-01

This article presents some of the results of a study carried out at the Brookhaven National Laboratory's ALARA Center on doses to various worker groups in the U.S. nuclear industry. In this study, data from workers in the industry were divided into male and female groups; the average radiation dose of these tow groups and the correlation of dose with age are presented. The male and female workers were further considered in the various sectors of the industry, and correlations of dose with age for each sector were investigated. For male workers, a downward correlation with age was observed, while for women there appeared to be a slight upward correlation. Data form 13 PWR and 9 BWR plants shows that a small, but important, group of workers would be affected by the NCRP proposed constraint of workers' lifetime dose in rem being maintained less than their ages. Various techniques proposed by the plants to reduce dose to this critical group of workers are also presented

Genetic and Epigenetic Mechanisms That Maintain Hematopoietic Stem Cell Function

Science.gov (United States)

Kosan, Christian; Godmann, Maren

2016-01-01

All hematopoiesis cells develop from multipotent progenitor cells. Hematopoietic stem cells (HSC) have the ability to develop into all blood lineages but also maintain their stemness. Different molecular mechanisms have been identified that are crucial for regulating quiescence and self-renewal to maintain the stem cell pool and for inducing proliferation and lineage differentiation. The stem cell niche provides the microenvironment to keep HSC in a quiescent state. Furthermore, several transcription factors and epigenetic modifiers are involved in this process. These create modifications that regulate the cell fate in a more or less reversible and dynamic way and contribute to HSC homeostasis. In addition, HSC respond in a unique way to DNA damage. These mechanisms also contribute to the regulation of HSC function and are essential to ensure viability after DNA damage. How HSC maintain their quiescent stage during the entire life is still matter of ongoing research. Here we will focus on the molecular mechanisms that regulate HSC function. PMID:26798358

Multi-Voxel Decoding and the Topography of Maintained Information During Visual Working Memory.

Lee, Sue-Hyun; Baker, Chris I

2016-01-01

The ability to maintain representations in the absence of external sensory stimulation, such as in working memory, is critical for guiding human behavior. Human functional brain imaging studies suggest that visual working memory can recruit a network of brain regions from visual to parietal to prefrontal cortex. In this review, we focus on the maintenance of representations during visual working memory and discuss factors determining the topography of those representations. In particular, we review recent studies employing multi-voxel pattern analysis (MVPA) that demonstrate decoding of the maintained content in visual cortex, providing support for a "sensory recruitment" model of visual working memory. However, there is some evidence that maintained content can also be decoded in areas outside of visual cortex, including parietal and frontal cortex. We suggest that the ability to maintain representations during working memory is a general property of cortex, not restricted to specific areas, and argue that it is important to consider the nature of the information that must be maintained. Such information-content is critically determined by the task and the recruitment of specific regions during visual working memory will be both task- and stimulus-dependent. Thus, the common finding of maintained information in visual, but not parietal or prefrontal, cortex may be more of a reflection of the need to maintain specific types of visual information and not of a privileged role of visual cortex in maintenance.

Group dynamics.

Science.gov (United States)

Scandiffio, A L

1990-12-01

Group dynamics play a significant role within any organization, culture, or unit. The important thing to remember with any of these structures is that they are made up of people--people with different ideas, motivations, background, and sometimes different agendas. Most groups, formal or informal, look for a leader in an effort to maintain cohesiveness of the unit. At times, that cultural bond must be developed; once developed, it must be nurtured. There are also times that one of the group no longer finds the culture comfortable and begins to act out behaviorally. It is these times that become trying for the leader as she or he attempts to remain objective when that which was once in the building phase of group cohesiveness starts to fall apart. At all times, the manager must continue to view the employee creating the disturbance as an integral part of the group. It is at this time that it is beneficial to perceive the employee exhibiting problem behaviors as a special employee, as one who needs the benefit of your experience and skills, as one who is still part of the group. It is also during this time that the manager should focus upon her or his own views in the area of power, communication, and the corporate culture of the unit that one has established before attempting to understand another's point of view. Once we understand our own motivation and accept ourselves, it is then that we may move on to offer assistance to another. Once we understand our insecurities recognizing staff dysfunction as a symptom of system dysfunction will not be so threatening to the concept of the manager that we perceive ourselves to be. It takes a secure person to admit that she or he favors staff before deciding to do something to change things. The important thing to know is that it can be done. The favored staff can find a new way of relating to others, the special employee can find new modes of behavior (and even find self-esteem in the process), the group can find new ways

Based on pre-clinical studies suggesting that magnesium (Mg) reduces cocaine self-administration and potentiates the antinociceptive effects of morphine, we conducted a preliminary randomized clinical trial investigating Mg for the treatment of illicit cocaine and opiate use. Eighteen methadone-maintained patients who used illicit opiates and cocaine received either Mg (732 mg/day) or placebo for 12 weeks. Overall, findings showed that the percentage of urine screens testing positive for opiates in the Mg group (22.6%) was half that of the placebo group (46.4%), p = .04; the difference was even greater in the "medication compliant" sample (Mg: 16.3%, placebo: 47.9%), p = .02. Cocaine craving was lower in the Mg compared to the placebo group, but there was no difference between groups in cocaine use. These preliminary findings suggest that Mg may have a beneficial effect for reducing illicit opiate use. It is possible that a higher dose of Mg than was used in this study may be needed to decrease cocaine use.

The FORATOM Transport Working Group

Lehmann, P.

2000-01-01

Based in Brussels, the European atomic forum FORATOM is the trade association of the European nuclear industry which was established in the early 1960s to promote nuclear power and to facilitate relations with the European institutions. One of the main mechanisms which FORATOM uses, in its dealings with the European Commission and other international organisations, is the involvement of several working groups bringing together groups of experts drawn from the industrial companies in order to identify the issues and to develop the widest possible common views on which the industry must express its representative, substantial and deliverable opinion. The Transport Working Group (TWG) has the objective of dealing with transport of radioactive material, especially nuclear materials. The TWG usually meets three times a year in Brussels or another selected location. It has strong links with the European Commission which are evidenced by the fact that it officially represents the European nuclear industry, with the status of observer, at the meetings of the Standing Working Group on Safe Transport of Radioactive Material which was set up in 1982, upon a request of the European Parliament, to advise the European Commission in the field of safe transport of radioactive materials. The Standing Working Group (SWG) assists the European Union's Member States in the revision process of IAEA recommendations and helps a correct and harmonious application of these recommendations within the European Union. In previous years, the Standing Working Group has proposed over 40 different studies, financed by the European Commission, on important transport issues. The FORATOM TWG encourages its member organisations to participate in studies proposed by the Commission and has been cooperating for many years with the Commission in the field of many studies aimed to improve the application of transport regulations.

Tumpach, Chantal; Dwivedi, Puneet; Izlar, Robert; Cook, Chase

2018-05-01

Forestry Best Management Practices (BMPs) are critical in ensuring sustainable forest management in the United States because of their effectiveness in protecting water quality, reducing soil erosion, maintaining riparian habitat, and sustaining site productivity. The success of forestry BMPs depends heavily on coordination among primary stakeholder groups. It is important to understand perceptions of such groups for a successful forest policy formulation. We used the SWOT-AHP (Strengths, Weaknesses, Opportunities, and Threats analysis with the Analytical Hierarchy Process) framework to assess perceptions of three stakeholder groups (loggers, landowners, agency foresters) about forestry BMPs in Georgia, the largest roundwood producing state in the United States. The agency and logger stakeholder groups gave the highest priority to improved reputation under the strength category, whereas the landowner stakeholder group perceived sustainable forestry as the highest priority under the same category. Lack of landowner education was the highest priority under the weakness category for landowner and agency stakeholder groups, whereas the logger stakeholder group selected lack of trained personnel as the highest priority under the same category. Agency and landowner stakeholder groups gave the highest priority to training and education while loggers indicated maintenance of forest-based environmental benefits as their highest priority under the opportunity category. Finally, landowners and agency stakeholder groups perceived more regulations and restrictions as most significant in the threat category whereas the logger stakeholder group was most concerned about the insufficient accounting of cost sharing under the same category. Overall, selected stakeholder groups recognize the importance of forestry BMPs and had positive perceptions about them. A collaborative approach based on continuous feedback can streamline expectations of stakeholder groups about forestry BMPs in

Maintaining families’ well-being in everyday life

Directory of Open Access Journals (Sweden)

Kristina Ziegert

2011-05-01

Full Text Available The aim of this paper is to discuss how everyday life changes for the family in the event of chronic illness or disability. It changes physically due to loss of body function and socially due to time and other constraints related to treatment or lack of mobility. Equally important, there is a psychological impact due to the uncertainty of the future. The article will explore how family participation can help to maintain well-being in everyday life. The family should therefore focus on their own needs as much as on the needs of the family members who are ill. In order to maintain well-being in everyday life, it is crucial for the family to create routines and spend time doing things that they enjoy. By doing this, the family will create a rhythm of well-being regardless of the critical family situation. Family members and professional caregivers also need to come together at the beginning and during the illness or disability event to discuss changes that could be made day-to-day for all those involved, thereby making for an easier transition into care giving.

Experience of maintaining laboratory educational website's sustainability.

Dimenstein, Izak B

2016-01-01

Laboratory methodology websites are specialized niche websites. The visibility of a niche website transforms it into an authority site on a particular "niche of knowledge." This article presents some ways in which a laboratory methodology website can maintain its sustainability. The optimal composition of the website includes a basic content, a blog, and an ancillary part. This article discusses experimenting with the search engine optimization query results page. Strategic placement of keywords and even phrases, as well as fragmentation of the post's material, can improve the website's visibility to search engines. Hyperlinks open a chain reaction of additional links and draw attention to the previous posts. Publications in printed periodicals are a substantial part of a niche website presence on the Internet. Although this article explores a laboratory website on the basis of our hands-on expertise maintaining "Grossing Technology in Surgical Pathology" (www.grossing-technology.com) website with a high volume of traffic for more than a decade, the recommendations presented here for developing an authority website can be applied to other professional specialized websites. The authority websites visibility and sustainability are preconditions for aggregating them in a specialized educational laboratory portal.

Bonilla-Palomas, J L; Gámez-López, A L; Castillo-Domínguez, J C; Moreno-Conde, M; López-Ibáñez, M C; Anguita-Sánchez, M

2018-03-01

To assess the long-term effect of nutritional intervention on malnourished, hospitalised patients with heart failure (HF). A total of 120 malnourished patients hospitalized for HF were randomised to undergo (or not) an individual nutritional intervention for 6 months. The primary event was the combination of all-cause death and readmission for HF. We performed an intent-to-treat analysis and assessed the effect of the intervention at 24 months. The combined event occurred in 47.5% of the intervention group and in 73.8% of the control group (hazard ratio: 0.45; 95% confidence interval: 0.28-0.72; P=.001). Thirty-nine percent of the intervention group and 59% of the control group died (hazard ratio: 0.53; 95% confidence interval: 0.31-0.89; P=.017). A nutritional intervention for malnourished patients hospitalised for HF maintains its prognostic benefit in the long-term follow-up.

To follow or not? How animals in fusion-fission societies handle conflicting information during group decision-making.

Science.gov (United States)

Merkle, Jerod A; Sigaud, Marie; Fortin, Daniel

2015-08-01

When group members possess differing information about the environment, they may disagree on the best movement decision. Such conflicts result in group break-ups, and are therefore a fundamental driver of fusion-fission group dynamics. Yet, a paucity of empirical work hampers our understanding of how adaptive evolution has shaped plasticity in collective behaviours that promote and maintain fusion-fission dynamics. Using movement data from GPS-collared bison, we found that individuals constantly associated with other animals possessing different spatial knowledge, and both personal and conspecific information influenced an individual's patch choice decisions. During conflict situations, bison used group familiarity coupled with their knowledge of local foraging options and recently sampled resource quality when deciding to follow or leave a group - a tactic that led to energy-rewarding movements. Natural selection has shaped collective behaviours for coping with social conflicts and resource heterogeneity, which maintain fusion-fission dynamics and play an essential role in animal distribution. © 2015 John Wiley & Sons Ltd/CNRS.

The business case: collaborating to help employees maintain their mental well-being.

Science.gov (United States)

Sairanen, Sari; Matzanke, Deanna; Smeall, Doug

2011-01-01

There has been a change in the mindset of businesses in recent years. Companies are starting to realize that proactively helping their employees to maintain mental health is beneficial, both for their workers and their business. In this article, we present three different but complementary views - those of an advocate, an employer and a provider - on helping employees maintain mental, and physical, health. In the first section, Sari Sairanen outlines programs and services to manage stress and maintain mental health that have been developed by the Canadian Auto Workers' union and implemented in partnership with employers, wellness providers, service agencies and other community partners. The union focuses on raising awareness and providing education, as well as removing the stigma associated with mental illness. Deanna Matzanke, in her section, discusses the commitment of a company, Scotiabank, to create and maintain an inclusive and accessible workplace for all its employees. It has recently worked with providers to develop and implement integrated services dealing specifically with mental health illness and addiction, which aid not only its current employees but also possible future employees. Finally, Doug Smeall shares his observations as an insurer at Sun Life Financial, who has seen the rates of both short-term and long-term disabilities increase. He elaborates on the collaborative work between insurers and employers to help employees maintain their mental health, and to return to work sooner when issues do occur. Ultimately, this article argues that unions, employers and insurers can work together with partners and employees to promote and maintain employee health because, as Sairanen asserts, "preventing a problem in the first place is the best strategy."

The aim of this study was to evaluate the frequency of Candida species and presence of lesions in the oral cavity of patients with sickle cell anemia (SS). The study included 30 patients diagnosed with sickle cell anemia and taking hydroxyurea for at least 90 days (SS/HU+); and 39 patients with sickle cell anemia and without hydroxyurea therapy (SS/HU-). Two control groups were constituted by healthy individuals matched to the test groups in age, gender, and oral conditions (C/HU+ for SS/HU+ and C/HU- for SS/HU-). Oral clinical examination and anamnesis were performed. Yeasts were collected by oral rinses and identified by API system. Antifungal susceptibility evaluation was performed according to the CLSI methodology. Data obtained for microorganisms counts were compared by Student's t test (SS/HU+ vs. C/HU+ and SS/HU- vs. C/HU-) using MINITAB for Windows 1.4. Significance level was set at 5%. No oral candidosis lesions were detected. Significant differences in yeasts counts were observed between SS/HU- group and the respective control, but there were no differences between SS/HU+ and C/HU+. Candida albicans was the most prevalent species in all groups. Candida famata was observed both in SS and control groups. Candida dubliniensis, Candida glabrata, Candida krusei, Candida tropicalis, Candida pelliculosa, and Candida parapsilosis were observed only in SS groups. Most strains were susceptible to all antifungal agents. Hydroxyurea therapy seems to decrease candidal counts and resistance rate in sickle cell anemia patients. However, further studies should be conducted in the future to confirm this finding. Hydroxyurea therapy in sickle cell anemia patients maintains fungal species balance in oral cavity. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Effectiveness of a Unique Support Group for Physicians in a Physician Health Program.

State Physician Health Programs (PHPs) assess, support, and monitor physicians with mental, behavioral, medical, and substance abuse problems. Since their formation in the 1970s, PHPs have offered support groups following the 12-step model for recovery from substance use disorders (SUDs). However, few programs have developed support groups for physicians without SUDs. This study at the Massachusetts PHP (Physician Health Services Inc.) represents the first effort to survey physician attitudes concerning a unique support group that goes beyond classic addiction models. The group was initiated because of the observation that physicians with problems other than SUDs did not fit easily into the 12-step framework. It was hypothesized that such a group would be effective in helping participants control workplace stress, improve professional and personal relationships, and manage medical and psychiatric difficulties. With a response rate of 43% (85 respondents), the survey identified a strong overall impact of the Physician Health Services Inc. support group, identifying positive effects in all areas of personal and professional life: family and friends, wellness, professional relationships, and career. Respondents identified the role of the facilitator as particularly important, underscoring the facilitator's capacity to welcome participants, manage interactions, set limits, and maintain a supportive emotional tone. The implications for physician health extend from supporting a broader application of this model to using a skilled facilitator to manage groups intended to reduce the stress and burnout of present-day medical practice. The results encourage PHPs, hospitals, medical practices, and physician groups to consider implementing facilitated support groups as an additional tool for maintaining physician health.

Maintaining the design integrity of nuclear installations throughout their operating life. INSAG-19. A report by the International Nuclear Safety Advisory Group

International Nuclear Information System (INIS)

2003-01-01

A nuclear power plant design is the product of the activities of many organizations, and changes to that design will occur continuously over the plant's lifetime. Reactor plants are designed to operate for a long period of time, typically 40 years, which may be extended for several decades. This period of time spans several working lifetimes of the staff of the plant, and its length represents a very specific challenge to safety and to the corporate asset management of the enterprise. It also implies that the vendor structure required to support the plant can be expected to change substantially during the plant's lifetime. this INSAG report discusses the problem of maintaining the integrity of design of a nuclear power plant over its entire lifetime in order to achieve a continuous high level of safety.

To formulate evidence-based guidelines on the appropriate use of space maintaining appliances to prevent or reduce the severity of malocclusion in the permanent dentition following the premature loss of primary teeth. Placement of lingual arch, palatal arch, band-loop, crown-loop, and intra-alveolar space maintainers. Reduced prevalence or severity of space loss in the primary or mixed dentition, reduced prevalence or severity of malocclusion in the permanent dentition measured as significant changes in: crowding, ectopic eruption, impacted teeth, Angle's class II or III occlusion, crossbite, deep overbite, deep overjet, or midline shift. Articles published from 1966 to 1996, located though Medline searches. Only clinical trials, cohort studies, case-control studies, or large case series were considered. Relevant clinical findings were evaluated and categorized using evidence-based methods and values established by the Canadian Task Force on the Periodic Health Examination. A recommendation was developed for the use of space maintainers. The potential benefits of using space maintaining appliances include reduced prevalence or severity of: crowding, ectopic eruption, tooth impaction, crossbite, excessive overbite and overjet, and poor molar relationship. Other advantages include the potential for considerable cost savings by reducing the need for future orthodontic treatment. The potential disadvantages of using space maintaining appliances include soft tissue impingement, interference with eruption of adjacent teeth, pain, plaque accumulation, caries, and broken, dislodged or lost appliances. There is poor evidence to recommend for or against the use of space maintainers to prevent or reduce the severity of malocclusion in the permanent dentition (see Table 1, Recommendation C) Decisions regarding the use of space maintainers must therefore be guided by factors other than scientific evidence.

Exploring the Influence of Student Focus Groups in Their Professional and Personal Development

A scientific career is often more than a 9-to-5 commitment, both in terms of time and passion. An important factor that fuels this passion is engaging with the community on many levels. In the history of education and professional development, there are numerous studies that emphasis the importance of surrounding groups and like-minded peers in one's professional and personal development in a less constrained environment. In our experience, in modern days where students are surrounded with too much information and yet too little clear signal, the idea of mentor and advisor can no longer limit to one or two people. We strongly feel it is imperative to have the opportunity to share expertise on scientific issues, career options, develop presenting and writing skills, participate in professional volunteer activities with alike and advanced colleagues, share future opportunities, and successfully navigating life both inside and outside of graduate school in a relaxed environment. Most of the professional scientific and engineering communities put a lot of effort to create and maintain professional groups in masters and Ph.D. levels but the dynamics within these groups prove it to be very different and it is challenging to maintain both momentum and productivity. Authors of this report would present their experience in creating, running and maintaining various student groups in the discipline of physics, astronomy, planetary science, hydrology, and optical engineering in US, Europe and Middle East. The common factors and differences based on the supportive community, location, and the educational level would be discussed. An outline of potential helpful factors within the academic institutes and professional communities would be presented based on the examination on various successful and unsuccessful experiences.

Maintainability must be designed into long-duration spacecraft and equipment to provide the required high probability of mission success with the least cost and weight. The ability to perform repairs quickly and easily in a space environment can be achieved by imposing specific maintainability design criteria on spacecraft equipment design and installation. A study was funded to investigate and define design criteria for electronic equipment that would permit rapid removal and replacement in a space environment. The results of the study are discussed together with subsequent simulated zero-g demonstration tests of a mockup with new concepts for packaging.

Maintaining experiences of nature as a city grows

Full Text Available Experiences of nature contribute to human health and well-being, yet as the world's population continues to concentrate in towns and cities there is mounting concern that these experiences are diminishing. Despite this, little is known about how we can maintain experiences of nature as cities grow. Here, we quantify how people's opportunities to experience nature might change with future urban growth in the city of Brisbane, Australia. We simulated the addition of 84,642 houses under compact and sprawling growth scenarios and modeled changes in people's opportunities to experience nature by estimating changes in backyard size, public green space provision, and bird species richness close to households. We discovered that the form of urban growth could strongly influence people's opportunities to experience nature in a way that is highly nonrandom across the socioeconomic gradient. Under a sprawling pattern of development, with low residential densities and few interstitial green spaces, our models suggest severe declines in access to public green space and bird species richness around people's homes. These declines are predicted to be concentrated in socioeconomically disadvantaged areas of the city. Compact development leads to greater reductions in backyard size, but smaller declines in access to public green space and bird species richness. Our results point to a difficult trade-off; residential infill will maintain larger green spaces and higher overall bird diversity but reduce backyard sizes, impacting people's opportunities to experience nature in a different way. Careful planning is needed to balance the availability of public and private urban green spaces to ensure that the opportunities for people to experience nature are maintained as urbanization continues.

Quantum group and quantum symmetry

International Nuclear Information System (INIS)

Chang Zhe.

1994-05-01

This is a self-contained review on the theory of quantum group and its applications to modern physics. A brief introduction is given to the Yang-Baxter equation in integrable quantum field theory and lattice statistical physics. The quantum group is primarily introduced as a systematic method for solving the Yang-Baxter equation. Quantum group theory is presented within the framework of quantum double through quantizing Lie bi-algebra. Both the highest weight and the cyclic representations are investigated for the quantum group and emphasis is laid on the new features of representations for q being a root of unity. Quantum symmetries are explored in selected topics of modern physics. For a Hamiltonian system the quantum symmetry is an enlarged symmetry that maintains invariance of equations of motion and allows a deformation of the Hamiltonian and symplectic form. The configuration space of the integrable lattice model is analyzed in terms of the representation theory of quantum group. By means of constructing the Young operators of quantum group, the Schroedinger equation of the model is transformed to be a set of coupled linear equations that can be solved by the standard method. Quantum symmetry of the minimal model and the WZNW model in conformal field theory is a hidden symmetry expressed in terms of screened vertex operators, and has a deep interplay with the Virasoro algebra. In quantum group approach a complete description for vibrating and rotating diatomic molecules is given. The exact selection rules and wave functions are obtained. The Taylor expansion of the analytic formulas of the approach reproduces the famous Dunham expansion. (author). 133 refs, 20 figs

Jaradata, Mustafa K.; Park, Chang Je; Lee, Byungchul

2013-01-01

In order to maintain a self-sustaining steady-state chain reaction, more fuel than is necessary in order to maintain a steady state chain reaction must be loaded. The introduction of this excess fuel increases the net multiplication capability of the system. In this paper MCNPX and multi-group nodal diffusion theory will be used for depletion calculations for MTR core. The eigenvalue and power distribution in the core will be compared for different burnup. Multi-group nodal diffusion theory with combination of NEWT-TRITON system was used to perform depletion calculations for 3Χ3 MTR core. 2G and 6G approximations were used and compared with MCNPX results for 2G approximation the maximum difference from MCNPX was 40 mk and for 6G approximation was 6 mk which is comparable to the MCNPX results. The calculated power using nodal code was almost the same MCNPX results. Finally the results of the multi-group nodal theory were acceptable and comparable to the calculated using MCNPX

Evidence suggests that physical activity and healthy diets may help to maintain cognitive function, reducing risks of developing Alzheimer's disease and vascular dementia. Using a cross-cultural focus, we describe older adults' awareness about cognitive health, and their ideas about how to inform and motivate others to engage in activities that may maintain brain health. Nineteen focus groups were conducted in 3 states (California, North Carolina, South Carolina) with 177 adults aged 50 years and older. Six groups were with African Americans (AAs), 4 with Chinese, 3 with Vietnamese, 4 with non-Hispanic Whites, and 2 with American Indians (AIs). A qualitative thematic analysis was conducted. Many participants did not recall reading or hearing about brain health in the media. Participants recommended a multimedia approach to inform others about brain health. Both interpersonal and social/group motivational strategies were suggested. Word of mouth and testimonials were recommended most often by Chinese and Vietnamese. AAs and AIs suggested brain health education at church; AAs, Chinese, and Vietnamese said brain health slogans should be spiritual. Participants' perceived barriers to seeking brain health information included watching too much TV and confusing media information. Findings on communication strategies for reaching racial/ethnic groups with brain health information will help guide message and intervention development for diverse older adults.

The study aimed to identify desirable social, familial, reproductive, dietary, and lifestyle factors for maintaining normal body mass index (BMI) of urban affluent women (25-45 years) in Delhi, India. A total of 387 urban affluent women with at least one living child participated in this cross-sectional study conducted from March 2008 to April 2010. Women were classified into four BMI categories on the basis of World Health Organization (WHO; 2004) classification for Asians. Significant factors for maintaining normal BMI were: Younger age, less parity, nuclear family, normal weight status of parents, postpartum weight gain between 2 and 3 kg, regularity in taking meals, fixed meal size, self-perceived normal weight, and shorter sitting time and television viewing time. Multivariate regression analysis identified five determining factors for maintaining BMI, which are normal weight of father, self-perceived normal weight, fixed meal size, sitting time less than 6 h/day, and television viewing time less than 1 h/day. By small lifestyle modifications, normal BMI can be maintained.

Maintaining ancient organelles: mitochondrial biogenesis and maturation.

Vega, Rick B; Horton, Julie L; Kelly, Daniel P

2015-05-22

The ultrastructure of the cardiac myocyte is remarkable for the high density of mitochondria tightly packed between sarcomeres. This structural organization is designed to provide energy in the form of ATP to fuel normal pump function of the heart. A complex system comprised of regulatory factors and energy metabolic machinery, encoded by both mitochondrial and nuclear genomes, is required for the coordinate control of cardiac mitochondrial biogenesis, maturation, and high-capacity function. This process involves the action of a transcriptional regulatory network that builds and maintains the mitochondrial genome and drives the expression of the energy transduction machinery. This finely tuned system is responsive to developmental and physiological cues, as well as changes in fuel substrate availability. Deficiency of components critical for mitochondrial energy production frequently manifests as a cardiomyopathic phenotype, underscoring the requirement to maintain high respiration rates in the heart. Although a precise causative role is not clear, there is increasing evidence that perturbations in this regulatory system occur in the hypertrophied and failing heart. This review summarizes current knowledge and highlights recent advances in our understanding of the transcriptional regulatory factors and signaling networks that serve to regulate mitochondrial biogenesis and function in the mammalian heart. © 2015 American Heart Association, Inc.

2015-11-01

Full Text Available Background: Several studies have analyzed the functions of foods and dietary constituents in the dynamics of alcohol metabolism. However, few studies have reported the function of dietary fibers in the dynamics of alcohol metabolism. Objective: We assessed the effects of botanical foods that contain dietary fibers on alcohol metabolism. Methods: The ability of the water-insoluble fraction (WIF of 18 kinds of botanical foods to maintain 15% (v/v ethanol solution was examined using easily handled filtration. A simple linear regression analysis was performed to examine the correlation between the filtered volumes and blood ethanol concentration (BEC in F344 rats 4 h after the ingestion of 4.0 g/kg of ethanol following dosage of 2.5% (w/v WIF of the experimental botanical foods. Furthermore, the supernatant (6.3 Brix; water-soluble fraction and precipitate (WIF of tomato, with a strong ethanol-maintaining ability, were obtained and BEC and the residual gastric ethanol in rats were determined 2 h after the administration of 4.0 g/kg of ethanol and the individuals fractions. Results: The filtered volumes of dropped ethanol solutions containing all the botanical foods tested except green peas were decreased compared with the ethanol solution without WIF (control. There was a significant correlation between the filtered volumes and blood ethanol concentration (BEC. There was no significant difference in the residual gastric ethanol between controls and the supernatant group; however, it was increased significantly in the WIF group than in controls or the supernatant group. Consistent with this, BEC reached a similar level in controls and the supernatant group but significantly decreased in the WIF group compared with controls or the supernatant group. Conclusions: These findings suggest that WIFs of botanical foods, which are mostly water-insoluble dietary fibers, possess the ability to absorb ethanol-containing solutions, and this ability correlates

There is good evidence that when people's needs and expectations regarding behaviour change are met, they are satisfied with that change, and maintain those changes. Despite this, there is a dearth of research on needs and expectations of walkers when initially attending walking groups and whether and how these needs and expectations have been satisfied after a period of attendance. Equally, there is an absence of research on how people who lead these groups understand walkers' needs and walk leaders' actions to address them. The present study was aimed at addressing both of these gaps in the research. Two preliminary thematic analyses were conducted on face-to-face interviews with (a) eight walkers when they joined walking groups, five of whom were interviewed three months later, and (b) eight walk leaders. A multi-perspective analysis building upon these preliminary analyses identified similarities and differences within the themes that emerged from the interviews with walkers and walk leaders. Walkers indicated that their main needs and expectations when joining walking groups were achieving long-term social and health benefits. At the follow up interviews, walkers indicated that satisfaction with meeting similar others within the groups was the main reason for continued attendance. Their main source of dissatisfaction was not feeling integrated in the existing walking groups. Walk leaders often acknowledged the same reasons for walkers joining and maintaining attendance at walking. However, they tended to attribute dissatisfaction and drop out to uncontrollable environmental factors and/or walkers' personalities. Walk leaders reported a lack of efficacy to effectively address walkers' needs. Interventions to increase retention of walkers should train walk leaders with the skills to help them modify the underlying psychological factors affecting walkers' maintenance at walking groups. This should result in greater retention of walkers in walking groups, thereby

Sea Hare Aplysia punctata (Mollusca: Gastropoda) Can Maintain Shell Calcification under Extreme Ocean Acidification.

Science.gov (United States)

Carey, Nicholas; Dupont, Sam; Sigwart, Julia D

2016-10-01

Ocean acidification is expected to cause energetic constraints upon marine calcifying organisms such as molluscs and echinoderms, because of the increased costs of building or maintaining shell material in lower pH. We examined metabolic rate, shell morphometry, and calcification in the sea hare Aplysia punctata under short-term exposure (19 days) to an extreme ocean acidification scenario (pH 7.3, ∼2800 μatm pCO 2 ), along with a group held in control conditions (pH 8.1, ∼344 μatm pCO 2 ). This gastropod and its congeners are broadly distributed and locally abundant grazers, and have an internal shell that protects the internal organs. Specimens were examined for metabolic rate via closed-chamber respirometry, followed by removal and examination of the shell under confocal microscopy. Staining using calcein determined the amount of new calcification that occurred over 6 days at the end of the acclimation period. The width of new, pre-calcified shell on the distal shell margin was also quantified as a proxy for overall shell growth. Aplysia punctata showed a 30% reduction in metabolic rate under low pH, but calcification was not affected. This species is apparently able to maintain calcification rate even under extreme low pH, and even when under the energetic constraints of lower metabolism. This finding adds to the evidence that calcification is a largely autonomous process of crystallization that occurs as long as suitable haeomocoel conditions are preserved. There was, however, evidence that the accretion of new, noncalcified shell material may have been reduced, which would lead to overall reduced shell growth under longer-term exposures to low pH independent of calcification. Our findings highlight that the chief impact of ocean acidification upon the ability of marine invertebrates to maintain their shell under low pH may be energetic constraints that hinder growth of supporting structure, rather than maintenance of calcification.

Patients with Usher syndrome face a special set of challenges in order to maintain their independence when their sight and hearing worsen. Three different types of Usher (I, II and III) are distinguished by differences in onset, progression and severity of hearing loss, and by the presence or absence of balance problems. In this study 93 Usher patients from seven European countries filled out a questionnaire on maintaining independence (60 patients type I, 25 patients type II, four patients type III and four patients type unknown). Results of Usher type I and II patients are presented. Following the Nordic definition of maintaining independence in deaf-blindness, three domains are investigated: access to information, communication and mobility. Research variables in this study are: age and type of Usher, considered hearing loss- and the number of retinitis pigmentosa-related sight problems. Usher type I patients tend to need more help than Usher type II patients and the amount of help that they need grows when patients get older or when considered hearing loss worsens. No patterns in results were seen for the number of retinitis pigmentosa related sight problems.

2017-10-01

Over time computer scientists have been provided metrics to measure software maintainability. In existing literature, a large number of references can be found about this topic; nevertheless, a lack of quantitative assessment of maintainability metrics has been observed. In this paper, we summarize the challenges of adopting code measurements in the context of physics software system. In this pilot study, we have used Geant4 - a twenty-year-old software system - to conduct this research and set the grounds for further discussion.

Acoustic waves in M dwarfs: Maintaining a corona

Science.gov (United States)

Mullan, D. J.; Cheng, Q. Q.

1994-01-01

We use a time-dependent hydrodynamics code to follow the propagation of acoustic waves into the corona of an M dwarf star. An important qualitative difference between M dwarfs and stars such as the Sun is that the acoustic spectrum in M dwarfs is expected to peak at periods close to the acoustic cutoff P(sub A): this allows more effective penetration of waves into the corona. In our code, radiative losses in the photosphere, chromosphere, and corona are computed using Rosseland mean opacities, Mg II kappa and Ly alpha emission, and optically thin emissivities respectively. We find that acoustic heating can maintain a corona with a temperature of order 0.7-1 x 10(exp 6) K and a surface X-ray flux as large as 10(exp 5)ergs/sq cm/s. In a recent survey of X-rays from M dwarfs, some (20%-30%) of the stars lie at or below this limiting X-ray flux: we suggest that such stars may be candidates for acoustically maintained coronae.

The implementation of plan of the day selection for patients receiving radiotherapy (RT) for bladder cancer requires efficient and confident decision-making. This article describes the development of a training programme and maintenance of competency. Cone beam CT (CBCT) images acquired on patients receiving RT for bladder cancer were assessed to establish baseline competency and training needs. A training programme was implemented, and observers were asked to select planning target volumes (PTVs) on two groups of 20 patients' images. After clinical implementation, the PTVs chosen were reviewed offline, and an audit performed after 3 years. A mean of 73% (range, 53-93%) concordance rate was achieved prior to training. Subsequent to training, the mean score decreased to 66% (Round 1), then increased to 76% (Round 2). Six radiographers and two clinicians successfully completed the training programme. An independent observer reviewed the images offline after clinical implementation, and a 91% (126/139) concordance rate was achieved. During the audit, 125 CBCT images from 13 patients were reviewed by a single observer and concordance was 92%. Radiographer-led selection of plan of the day was implemented successfully with the use of a training programme and continual assessment. Quality has been maintained over a period of 3 years. The training programme was successful in achieving and maintaining competency for a plan of the day technique.

Distal forearm fractures, one of the most common fractures seen in the pediatric population, are regularly treated by closed reduction and casting. Our study investigates the effectiveness of Gore-Tex-lined casting in maintaining the reduction of 100% displaced distal forearm fractures compared with traditional cotton-lined casts. We screened all patients from February 2007 to July 2009 who presented to Children's Hospital in Birmingham, AL with a distal radius fracture. Only patients with 100% displaced distal radius fractures were eligible to be assigned to either the cotton-lined or Gore-Tex-lined cast groups. Power analysis was performed to identify an adequate patient sample size. The mean maximum change between initial post-reduction x-rays and follow-up x-rays for anterior-posterior (AP) angulation, AP displacement, lateral angulation, and lateral displacement of the radius were calculated for both cotton and Gore-Tex groups. The rate of subsequent intervention and/or unacceptable results for each group was also analyzed. Seven hundred and twenty-two patients were treated with distal radius fractures at our hospital with 59 patients eligible for inclusion in our study. Thirty-six of our patients were treated with cotton-lined casts, and 23 patients were treated with Gore-Tex-lined cast. The mean maximum change in AP angulation, AP displacement, lateral angulation, and lateral displacement of the radius after initial reduction was 9.2 degrees, 6.9%, 13.9 degrees, and 13.6%, respectively, for the cotton-lined cast group and 7.7 degrees, 6.1%, 14.6 degrees, and 9.6%, respectively, for the Gore-Tex-lined cast group. There were no statistical differences between the means of the 4 measurements (P=0.33, 0.69, 0.73, and 0.10, respectively). There were also no significant differences between groups for final AP and lateral angulation and displacement. Subgroup analysis showed no significant differences in all measurements between cotton and Gore-Tex groups. Gore

Does anatomy of the pubic arch interfere with the maintaining of erection?

Science.gov (United States)

Paul, Jean François; Virag, Ronald

2013-03-01

There are men who suffer from unsustainable erections without any identified cause of erectile dysfunction, raising the question if anatomical alterations could be involved. Since early anatomical studies, it has been proposed that to achieve full penile rigidity, the blood must be blocked inside the penis by compression of the deep dorsal vein (DDV), the main venous collector under pubic symphysis. Using a recently developed caverno computed tomography (CT) scan technique, allowing the evaluation of the venous drainage of the corpora cavernosa (CC) during erection, we have studied some anatomical conditions of this important part of the erectile phenomenon. Puboischial rami angles were measured in axial CT images and calculated strictly on the upper insertion point of the CC, using axial submillimeter slices in 37 patients divided into 3 groups depending on the results of the caverno CT scan: (i) no leak; (ii) superficial veins leaking; and (iii) drainage through the DDV and/or preprostatic plexus. In addition same angles were measured in two randomly unselected populations of men (N = 30), and women (N = 23) who underwent pelvic CT scan for various reasons, unrelated to their sexual or genital condition. The angles made by both puboischial rami were measured in patients with and without veno-occlusive dysfunction and in unselected samples of men and women. There is a significantly wider angle made by both puboischial rami in men without complete erection and without evidence of anomalous venous drainage (group 3) (72.2° ± 4.7° standard deviation [SD]), compared with both men with normal erection (group 1) (57.5 ± 5° SD) P drainage (group 2) (57.7 ± 6° SD) P < 0.00001. If confirmed in larger samples, these results raise new questions on the mechanism and the role of these significant anatomical variations, yet unknown, in maintaining or not full rigid erections. © 2012 International Society for Sexual Medicine.

Maintaining competence in radiological protection in emergency situations - a challenge for the 21st century

International Nuclear Information System (INIS)

Weiss, W.

2003-01-01

Full text: State of the art radiological protection in emergency situations requires specific resources and competence in a variety of scientific and technical areas. These include e.g. nuclear and reactor physics, metrology, health sciences, radiobiology, food production, waste management, and information technology. In many of these areas a high technical standard is currently available. This standard is based on great efforts of governments, universities/research institutions and the nuclear industry during the second half of the 20 th century. Although the number of scientists and technicians in these areas may appear to be sufficient today at least in some countries, there are strong indicators that future expertise is at risk. The indicators are declining university enrolment, dilution of university course content, high retirement expectations of staff members with little or no replacement planned. During the last decade many international organizations have analyzed the current situation and identified risk areas. Many proposals of general nature are available to take appropriate steps to maintain competence in the 21 st century. These proposals include the following recommendations for governments, for the industry, and for international and supra-national organisations. Governments are encouraged to engage in long term strategic planning and funding to maintain competence; organize networks of collaboration between specialised organisations to maintain critical groups size; take responsibility for ensuring that human resources are available to meet obligations; support 'educational networks' among universities, research institutions, and the industry; provide scholarships, fellowships, and traineeships as part of their funding policy. The industry is encouraged to maintain high level training and in house education to meet their specific needs; develop research programmes which are attractive for students and employees; improve co-operation with

Technology working group

International Nuclear Information System (INIS)

Tsujikura, Y.

2000-01-01

The workshop of 26-27 june 2000, on nuclear power Plant LIfe Management (PLIM), also included working groups in which major issues facing PLIM activities for nuclear power plants were identified and discussed. The first group was on Technology. Utilities should consider required provisions capacity by properly maintaining and preserving the existing power plants to the extent practicable and taking into account growing demand, limits of energy conservation, and difficulties in finding new power plant sites. Generally, the extension of the life of nuclear power plant (e.g. from 40 years to 60 years) is an attractive option for utilities, as the marginal cost of most existing nuclear power plants is lower than that of almost all other power sources. It is also an attractive option for environmental protection. Consequently, PLIM has become an important issue in the context of the regulatory reform of the electricity markets. Therefore, the three main objectives of the Technology working group are: 1) Documenting how the safety of nuclear power plants being operated for the long-term has been confirmed, and suggesting ways of sharing this information. 2) Addressing development of advanced maintenance technologies necessary over the plant lifetime, and clarifying their technical challenges. 3) Suggesting potential areas of research and development that might, be necessary. Some potential examples of such research include: - improving the effectiveness of maintenance methods to assure detection of incipient faults; - providing cost effective preventive maintenance programmes; - furnishing systematic, cost-effective refurbishment programmes framed to be consistent with efforts to extend the time between re-fuelling; - developing a methodology that moves routine maintenance on-line without compromising safety.

Balancing selection maintains cryptic colour morphs.

Science.gov (United States)

Wellenreuther, Maren

2017-11-01

Animals display incredibly diverse colour patterns, a testament to evolution's endless innovation in shaping life. In many species, the interplay between males and females in the pursuit of mates has driven the evolution of a myriad of colour forms, from the flashy peacock tail feathers to the tiniest colour markings in damselflies. In others, colour provides crypsis by allowing to blend into the background and to escape the eyes of predators. While the obvious benefits of this dazzling diversity for reproduction and survival seem straightforward, its maintenance is not. Theory predicts that genetic drift and various forms of selection reduce variation over time, making the persistence of colour variants over generations a puzzle. In this issue of Molecular Ecology, Lindtke et al. () study the cryptic colour morphs of Timema cristinae walking sticks to shed light on the genetic architecture and mechanisms that allow colour polymorphism maintenance over long timescales. By combining genome-wide data with phenotyping information from natural populations, they were able to map the green and melanistic colour to one genomic region with highly reduced effective recombination rate between two main chromosomal variants, consistent with an inversion polymorphism. These two main chromosomal variants showed geographically widespread heterozygote excess, and genomic signatures consistent with long-term balancing selection. A younger chromosomal variant was detected for the third morph, the green-striped colour morphs, in the same genomic regions as the melanistic and the green-unstriped morphs. Together, these results suggest that the genetic architecture of cryptic T. cristinae morphs is caused by nonrecombining genomic blocks that have been maintained over extended time periods by balancing selection making this study one of the few available empirical examples documenting that balancing selection of various forms may play an important role in maintaining adaptive genetic

Sister chromosome pairing maintains heterozygosity in parthenogenetic lizards.

Science.gov (United States)

Lutes, Aracely A; Neaves, William B; Baumann, Diana P; Wiegraebe, Winfried; Baumann, Peter

2010-03-11

Although bisexual reproduction has proven to be highly successful, parthenogenetic all-female populations occur frequently in certain taxa, including the whiptail lizards of the genus Aspidoscelis. Allozyme analysis revealed a high degree of fixed heterozygosity in these parthenogenetic species, supporting the view that they originated from hybridization events between related sexual species. It has remained unclear how the meiotic program is altered to produce diploid eggs while maintaining heterozygosity. Here we show that meiosis commences with twice the number of chromosomes in parthenogenetic versus sexual species, a mechanism that provides the basis for generating gametes with unreduced chromosome content without fundamental deviation from the classic meiotic program. Our observation of synaptonemal complexes and chiasmata demonstrate that a typical meiotic program occurs and that heterozygosity is not maintained by bypassing recombination. Instead, fluorescent in situ hybridization probes that distinguish between homologues reveal that bivalents form between sister chromosomes, the genetically identical products of the first of two premeiotic replication cycles. Sister chromosome pairing provides a mechanism for the maintenance of heterozygosity, which is critical for offsetting the reduced fitness associated with the lack of genetic diversity in parthenogenetic species.

Exploration and exploitation of radioactive ores (ilmenite, zircon and monazite) are considered as the main source of exposure to ionizing radiation of the population living in the coast of Analanjorofo Region (Fenerive-Est Districts, Rural municipality Ampasimbe Manantsatrana). Radioactivity measurements have been performed in this region. The distribution of natural radionuclide gamma-emitters ( 238 U, 232 Th and 40 K) and their respective annual effective dose rates have been determined for sand(s), water and air. The samples have been collected along and around the coast of the region. The radiation emitted from the natural radionuclide containing in the environmental samples has been determined by gamma spectrometry system and Radon meter (SARAD). Exposure dose rates at 1 m above the ground have been measured along the coast and in the villages around the exploitation sites. Dose rate measurements have been performed by Dosimeter Graetz X5DE, equipped of Geiger Muller Counter. Results have been compared with the reference values provided by IAEA (BSS 115) and UNSCEAR 2000.

In particular, the potential for monotony and boredom during a long-duration space voyage and the effect on motivation and productivity can be important considerations to the health and welfare of the crew. For the voyage to Mars, a design may be considered that will purposefully maintain some level of workload for the crew as a preventive measure for the deterioration of productivity that comes with boredom. This paper speculates on these considerations, on the appropriate level of workload for maximum productivity, and on what might be done during the mission to alleviate the problems caused by monotony and boredom.

Full Text Available Early orthodontic interventions are often initiated in the developing dentition to promote favorable developmental changes. Interceptive orthodontic can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. Premature loss of deciduous tooth or teeth can often destroy the integrity of normal occlusion. There are many space regaining and maintaining devices mentioned in literature. In this article, I present a simple space regaining method by a piece of nickel titanium (NiTi wire bonded between the teeth in active loop form, and the unique shape memory property of NiTi wire will upright or move the teeth and the lost space can be regained easily.

Typical form of neurons is crucially important for their functions. This is maintained by microtubules and associated proteins like tau. Hyperphosphorylation of tau is a major concern in neurodegenerative diseases. Glycogen synthase kinase3β (GSK3β) and cyclin-dependent protein kinase 5 (Cdk5) are the enzymes that govern tau phosphorylation. Currently, efforts are being made to target GSK3β and Cdk5 as possible therapeutic avenues to control tau phosphorylation and treat neurodegenerative diseases related to taupathies. In a number of studies, caloric restriction mimetic 2-deoxyglucose (C6H12O5) was found to be beneficial in improving the brain functions. However, no reports are available on the effect of 2-deoxyglucose 2-DG on tau phosphorylation. In the present study, hippocampal pyramidal neurons from E17 mouse embryos were isolated and cultured on poly-L-lysine-coated coverslips. Neurons from the experimental group were treated with 10 mM 2-deoxyglucose. The treatment of 2-DG resulted in healthier neuronal morphology in terms of significantly lower number of cytoplasmic vacuoles, little or no membrane blebbings, maintained axon hillock and intact neurites. There were decreased immunofluorescence signals for GSK3β, pTau at Ser262, Cdk5 and pTau at Ser235 suggesting decreased tau phosphorylation, which was further confirmed by Western blotting. The results indicate the beneficial effects of 2-DG in controlling the tau phosphorylation and maintaining the healthy neuronal cytoarchitecture.

Governments are promoting the importance of maintaining cognitive health into older age to minimize risk of cognitive decline and dementia. Older people with amnestic mild cognitive impairment (aMCI) are particularly vulnerable to memory challenges in daily activities and are seeking ways to maintain independent living. To evaluate the effectiveness of memory groups for improving memory strategies and memory ability of older people, especially those with aMCI. 113 healthy older adults (HOA) and 106 adults with aMCI were randomized to a six-week memory group or a waitlist control condition. Outcome was evaluated through knowledge and use of memory strategies, memory ability (self-report and neuropsychological tests), and wellbeing. Assessments included a six-month follow-up. Using intention to treat analyses, there were intervention effects for HOA and aMCI groups in strategy knowledge (HOA: η2= 0.20; aMCI: η2= 0.06), strategy use (HOA: η2= 0.18; aMCI: η2= 0.08), and wellbeing (HOA: η2= 0.11; aMCI: η2= 0.05). There were also intervention effects in the HOA group, but not the aMCI group, in self-reported memory ability (η2= 0.06) and prospective memory tests (η2= 0.02). By six-month follow-up, gains were found on most HOA outcomes. In the aMCI group gains were found in strategy use, and by this stage, gains in prospective memory were also found. Memory groups can engage older people in techniques for maintaining cognitive health and improve memory performance, but more modest benefits are seen for older adults with aMCI.

Evidence for contact calls in fish: conspecific vocalisations and ambient soundscape influence group cohesion in a nocturnal species

Science.gov (United States)

van Oosterom, L.; Montgomery, J. C.; Jeffs, A. G.; Radford, C. A.

2016-01-01

Soundscapes provide a new tool for the study of fish communities. Bigeyes (Pempheris adspersa) are nocturnal planktivorous reef fish, feed in loose shoals and are soniferous. These vocalisations have been suggested to be contact calls to maintain group cohesion, however direct evidence for this is absent, despite the fact that contact calls are well documented for many other vertebrates, including marine mammals. For fish, direct evidence for group cohesion signals is restricted to the use of visual and hydrodynamic cues. In support of adding vocalisation as a contributing cue, our laboratory experiments show that bigeyes significantly increased group cohesion when exposed to recordings of ambient reef sound at higher sound levels while also decreasing vocalisations. These patterns of behaviour are consistent with acoustic masking. When exposed to playback of conspecific vocalisations, the group cohesion and vocalisation rates of bigeyes both significantly increased. These results provide the first direct experimental support for the hypotheses that vocalisations are used as contact calls to maintain group cohesion in fishes, making fish the evolutionarily oldest vertebrate group in which this phenomenon has been observed, and adding a new dimension to the interpretation of nocturnal reef soundscapes.

Understanding how to maintain compliance in the current regulatory climate

International Nuclear Information System (INIS)

Bignell, D.T.; Burns, R.

1995-01-01

High level radioactive waste facilities must maintain compliance with all regulatory requirements, even those requirements that have been promulgated after the facility was placed into operation. Facilities must aggressively pursue compliance because environmental laws often impose strict liability for violations; therefore, an honest mistake is no defense. Radioactive waste management is constantly under the public microscope, particularly those facilities that handle high-level radioactive waste. The Savannah River Site has effectively met the challenges of regulatory compliance in its HLRW facilities and plans are being formulated to meet future regulatory requirements as well. Understanding, aggressively achieving, and clearly demonstrating compliance is essential for the continued operations of radioactive waste management facilities. This paper examines how HLRW facilities are impacted by regulatory requirements and how compliance in this difficult area is achieved and maintained

The importance of university research in maintaining the nuclear option

International Nuclear Information System (INIS)

Bruschi, H.J.; Hochreiter, L.E.

1991-01-01

The role of the university in maintaining and revitalizing the nuclear option should have four goals. First, it must attract highly skilled students who have an interest in math and science and help foster their interest in nuclear science and engineering. Next, it must present a state-of-the-art educational program that contains meaningful research to maintain these students. The third goal of nuclear engineering departments is to provide the nontechnical student a fair assessment of benefits and risks associated with commercial nuclear power relative to other sources of electricity. Lastly, it must effectively communicate to all students a compelling vision of nuclear power as a vital energy resource that will grow. The most difficult role for the university is to successfully convey a future for those in the nuclear science and engineering program

Group music performance causes elevated pain thresholds and social bonding in small and large groups of singers

Science.gov (United States)

Weinstein, Daniel; Launay, Jacques; Pearce, Eiluned; Dunbar, Robin I. M.; Stewart, Lauren

2016-01-01

Over our evolutionary history, humans have faced the problem of how to create and maintain social bonds in progressively larger groups compared to those of our primate ancestors. Evidence from historical and anthropological records suggests that group music-making might act as a mechanism by which this large-scale social bonding could occur. While previous research has shown effects of music making on social bonds in small group contexts, the question of whether this effect ‘scales up’ to larger groups is particularly important when considering the potential role of music for large-scale social bonding. The current study recruited individuals from a community choir that met in both small (n = 20 – 80) and large (a ‘megachoir’ combining individuals from the smaller subchoirs n = 232) group contexts. Participants gave self-report measures (via a survey) of social bonding and had pain threshold measurements taken (as a proxy for endorphin release) before and after 90 minutes of singing. Results showed that feelings of inclusion, connectivity, positive affect, and measures of endorphin release all increased across singing rehearsals and that the influence of group singing was comparable for pain thresholds in the large versus small group context. Levels of social closeness were found to be greater at pre- and post-levels for the small choir condition. However, the large choir condition experienced a greater change in social closeness as compared to the small condition. The finding that singing together fosters social closeness – even in large contexts where individuals are not known to each other – is consistent with evolutionary accounts that emphasize the role of music in social bonding, particularly in the context of creating larger cohesive groups than other primates are able to manage.

In this second phase the impact of unscheduled maintenance, several vacuum wall arrangements, and maintenance of other reactor interfacing subsystems and maintenance equipment are added to the evaluation of the maintainability of the fusion power reactor concepts. Four concepts are normalized to common performance parameters and evaluated for their capability to achieve availability and cost of electricity goals considering both scheduled and unscheduled maintenance. The results of this evaluation are used to generate a series of maintainability design guidelines and to select the more desirable features and design options which are used to configure a preliminary reactor concept having improved maintainability

2016-06-01

We examined motives for adopting and maintaining yoga practice in a national survey of yoga practitioners (360 yoga students, 156 yoga teachers). Both students and teachers adopted yoga practice primarily for exercise and stress relief, but reported many other reasons, including flexibility, getting into shape, and depression/anxiety relief. Over 62 percent of students and 85 percent of teachers reported having changed their primary reason for practicing or discovering other reasons; for both, the top changed primary reason was spirituality. Findings suggest that most initiate yoga practice for exercise and stress relief, but for many, spirituality becomes their primary reason for maintaining practice. © The Author(s) 2014.

A controlled experiment on the impact of software structure on maintainability

Science.gov (United States)

Rombach, Dieter H.

1987-01-01

The impact of software structure on maintainability aspects including comprehensibility, locality, modifiability, and reusability in a distributed system environment is studied in a controlled maintenance experiment involving six medium-size distributed software systems implemented in LADY (language for distributed systems) and six in an extended version of sequential PASCAL. For all maintenance aspects except reusability, the results were quantitatively given in terms of complexity metrics which could be automated. The results showed LADY to be better suited to the development of maintainable software than the extension of sequential PASCAL. The strong typing combined with high parametrization of units is suggested to improve the reusability of units in LADY.

The U.S. Department of Energy (DOE) Office of Legacy Management (LM) is an integral part of DOE's strategy to ensure that legacy liabilities of former nuclear weapons production sites are properly managed following the completion of environmental cleanup activities. In the area of environmental legacy management, records management is crucial to the protection of health, environmental, and legal interests of the Department and the public. LM is responsible for maintaining long-term surveillance and maintenance (LTS and M) records in performance of its mission. Maintaining access to the knowledge contained in these record collections is one of LM's primary responsibilities. To fulfill this responsibility, LM established a consolidated records management facility, the LM Business Center (LMBC), to house physical media records and electronic records. A new electronic record keeping system (ERKS) was needed to replace an obsolete system while helping to ensure LM is able to meet ongoing responsibilities to maintain access to knowledge and control the life cycle management of records.

Guo, Weian; Si, Chengyong; Xue, Yu; Mao, Yanfen; Wang, Lei; Wu, Qidi

2017-05-04

Particle Swarm Optimization (PSO) is a popular algorithm which is widely investigated and well implemented in many areas. However, the canonical PSO does not perform well in population diversity maintenance so that usually leads to a premature convergence or local optima. To address this issue, we propose a variant of PSO named Grouping PSO with Personal- Best-Position (Pbest) Guidance (GPSO-PG) which maintains the population diversity by preserving the diversity of exemplars. On one hand, we adopt uniform random allocation strategy to assign particles into different groups and in each group the losers will learn from the winner. On the other hand, we employ personal historical best position of each particle in social learning rather than the current global best particle. In this way, the exemplars diversity increases and the effect from the global best particle is eliminated. We test the proposed algorithm to the benchmarks in CEC 2008 and CEC 2010, which concern the large scale optimization problems (LSOPs). By comparing several current peer algorithms, GPSO-PG exhibits a competitive performance to maintain population diversity and obtains a satisfactory performance to the problems.

2014-01-01

In response to two White Papers submitted to the Astro2010 Decadal Survey (1,2), a new AAS Working Group on Astroinformatics and Astrostatistics (WGAA) has been approved by the AAS Council at the 220th Meeting, June 2012, in Anchorage. The motivation for this WG is the growing importance of the interface between astronomy and various branches of applied mathematics, computer science and the emerging field of data science. With the new data-intensive projects envisioned for the coming decade, the need for advice derived from the focused attention of a group of AAS members who work in these areas is bound to increase. The Working Group is charged with spreading awareness of rapidly advancing computational techniques, sophsticated statistical methods, and highly capble software to further the goals of astronomical and astrophysical research. The three main strategic goals adopted by the WGAA Steering Committee for the next few years are to: (i) develop, organize and maintain methodological resources (such as software tools, papers, books, and lectures); (ii) enhance human resources (such as foster the creation of career paths, establish a Speakers' Bureau, establish and maintain an archived discussion forum, enable periodic news distribution); and (iii) organize topical meetings. The WGAA Steering Committee at this time includes twelve members: Kirk Borne, George Djorgovski, Eric Feigelson, Eric Ford, Alyssa Goodman, Joe Hilbe, Zeljko Ivezic (chair), Ashish Mahabal, Aneta Siemiginowska, Alex Szalay, Rick White, and Padma Yanamandra-Fisher. I will summarize our accomplishments since July 2012.

Establishing and maintaining international collaborative research teams: an autobiographical insight

Directory of Open Access Journals (Sweden)

T J Carr

2013-07-01

Full Text Available Despite the growing impetus for international collaborative research teams (ICRT, there are relatively few resources available to guide and support researchers through the processes of establishing and maintaining ICRTs. In particular, no articles were found that provided researchers’ firsthand accounts of being a member of such a team. Having access to such personal accounts can help both experienced and novice researchers learn more directly about what to expect, as well as the benefits, challenges, pitfalls, and success strategies for establishing and maintaining ICRTs. The authors used phenomenological autobiographical reflective journaling to capture their experiences as members of ICRTs. In this article we provide an overview of key themes that emerged from the analysis of our reflections as members of ICRTs. These themes include: benefits, challenges, and strategies for success. Our aim is to share our first-hand experiences of what it is like to establish and participate in ICRT. It is not our intention to provide readers with prescriptive guidelines on how to set up and maintain ICRTs. Every ICRT is unique and some of these ideas may or may not apply in every case. Instead, we are describing what worked for us, hoping that others may benefit from our experience. Consequently, we suggest that the focus of ICRT should be on the benefits thereof which promote and encourage interaction between disciplines, transfer of knowledge and techniques and personal and professional development.

DNMT1 maintains progenitor function in self-renewing somatic tissue.

Science.gov (United States)

Sen, George L; Reuter, Jason A; Webster, Daniel E; Zhu, Lilly; Khavari, Paul A

2010-01-28

Progenitor cells maintain self-renewing tissues throughout life by sustaining their capacity for proliferation while suppressing cell cycle exit and terminal differentiation. DNA methylation provides a potential epigenetic mechanism for the cellular memory needed to preserve the somatic progenitor state through repeated cell divisions. DNA methyltransferase 1 (DNMT1) maintains DNA methylation patterns after cellular replication. Although dispensable for embryonic stem cell maintenance, the role for DNMT1 in maintaining the progenitor state in constantly replenished somatic tissues, such as mammalian epidermis, is unclear. Here we show that DNMT1 is essential for epidermal progenitor cell function. DNMT1 protein was found enriched in undifferentiated cells, where it was required to retain proliferative stamina and suppress differentiation. In tissue, DNMT1 depletion led to exit from the progenitor cell compartment, premature differentiation and eventual tissue loss. Genome-wide analysis showed that a significant portion of epidermal differentiation gene promoters were methylated in self-renewing conditions but were subsequently demethylated during differentiation. Furthermore, UHRF1 (refs 9, 10), a component of the DNA methylation machinery that targets DNMT1 to hemi-methylated DNA, is also necessary to suppress premature differentiation and sustain proliferation. In contrast, Gadd45A and B, which promote active DNA demethylation, are required for full epidermal differentiation gene induction. These data demonstrate that proteins involved in the dynamic regulation of DNA methylation patterns are required for progenitor maintenance and self-renewal in mammalian somatic tissue.

Care and management of a stoma: maintaining peristomal skin health.

Science.gov (United States)

Boyles, Anna; Hunt, Sharon

2016-09-22

It is estimated that around one in 500 people in the UK are living with a stoma, with approximately 21 000 operations that result in stoma formation being performed each year ( Colostomy Association, 2016 ). These people face a unique set of challenges in maintaining the integrity of their peristomal skin. This article explores the normal structure and function of skin and how the care and management of a stoma presents challenges for maintaining peristomal skin health. Particular focus is paid to the incidence of skin problems for those living with a stoma, whether it is temporary or permanent, and the factors that contribute to skin breakdown in this population. Wider factors such as the central role of the clinical nurse specialist and the impact of product usage on positive outcomes and health economics are also considered.

Reciprocity and the Tragedies of Maintaining and Providing the Commons.

Science.gov (United States)

Gächter, Simon; Kölle, Felix; Quercia, Simone

2017-09-01

Social cooperation often requires collectively beneficial but individually costly restraint to maintain a public good1-4, or it needs costly generosity to create one1,5. Status quo effects6 predict that maintaining a public good is easier than providing a new one. Here we show experimentally and with simulations that even under identical incentives, low levels of cooperation (the 'tragedy of the commons'2) are systematically more likely in Maintenance than Provision. Across three series of experiments, we find that strong and weak positive reciprocity, known to be fundamental tendencies underpinning human cooperation7-10, are substantially diminished under Maintenance compared to Provision. As we show in a fourth experiment, the opposite holds for negative reciprocity ('punishment'). Our findings suggest that incentives to avoid the 'tragedy of the commons' need to contend with dilemma-specific reciprocity.

Although molecular methods, such as QTL mapping, have revealed a number of loci with large effects, it is still likely that the bulk of quantitative variability is due to multiple factors, each with small effect. Typically, these have a large additive component. Conventional wisdom argues that selection, natural or artificial, uses up additive variance and thus depletes its supply. Over time, the variance should be reduced, and at equilibrium be near zero. This is especially expected for fitness and traits highly correlated with it. Yet, populations typically have a great deal of additive variance, and do not seem to run out of genetic variability even after many generations of directional selection. Long-term selection experiments show that populations continue to retain seemingly undiminished additive variance despite large changes in the mean value. I propose that there are several reasons for this. (i) The environment is continually changing so that what was formerly most fit no longer is. (ii) There is an input of genetic variance from mutation, and sometimes from migration. (iii) As intermediate-frequency alleles increase in frequency towards one, producing less variance (as p --> 1, p(1 - p) --> 0), others that were originally near zero become more common and increase the variance. Thus, a roughly constant variance is maintained. (iv) There is always selection for fitness and for characters closely related to it. To the extent that the trait is heritable, later generations inherit a disproportionate number of genes acting additively on the trait, thus increasing genetic variance. For these reasons a selected population retains its ability to evolve. Of course, genes with large effect are also important. Conspicuous examples are the small number of loci that changed teosinte to maize, and major phylogenetic changes in the animal kingdom. The relative importance of these along with duplications, chromosome rearrangements, horizontal transmission and polyploidy

A new era of prosperity through power : maintaining BC's competitive advantage

International Nuclear Information System (INIS)

Potts, D.

2001-01-01

The availability of abundant low cost electric power has been a driving force behind British Columbia's economic growth. BC's low cost power resources can create a natural competitive economic advantage for the province. Electricity, as a publicly owned resource can offer many competitive advantages for business in British Columbia, if managed correctly. However, it was noted that meaningful economic advantages can only be realized if the existing power resources in the province are operated efficiently and priced at or close to cost. In the 1980s, the Joint Industry Electricity Steering Committee (JIESC) was formed following the regulation of BC Hydro by BC Utilities Commission. It became clear that maintaining low rates for electricity was a public issue that needed input from other governmental forums if JIESC was to be successful. The major sectors represented by JIESC include pulp and paper, mining, and electrochemicals. This paper listed each member company. In order to turn BC's economy around and re-establish the province as a leading economy in Canada, the following recommendations have been proposed for the short term: (1) maintain an ample supply of low cost power for the future, (2) remove the provincial sales tax on the purchase of electric power used for manufacturing and processing, (3) extend the current rate freeze, (4) initiate a long-term resource acquisition and transmission expansion strategy to assure the availability of ample supplies of low cost power. Recommendations for the long term include: (1) maintain regulated cost based rates, (2) develop ample low cost power, (3) utilize downstream benefits, (4) provide a role for the private sector, (5) maintain adequate transmission facilities, (6) reduce government revenues, and (7) instill customer driven management. 3 figs

Full Text Available This study aimed to assess the impact of a multidisciplinary program of obesity treatment (MPOT on adolescents who have maintained/gained weight or lost weight. Eighty-six adolescents aged 10–18 years were allocated in either the intervention group (IG; n = 44 or the control group (CG; n = 42. Each group was divided into two more groups: weight maintenance/gain and weight loss, as assessed after the intervention. The MPOT lasted 16 weeks and was conducted by a multidisciplinary team based on cognitive-behavioral therapy. We analyzed body composition and cardiometabolic parameters prior to and after the intervention. Adolescents from the IG who lost weight showed improvements in maximal oxygen uptake (23.54 ± 5.30 mL/kg/minute vs. 25.39 ± 5.63 mL/kg/minute, body fat percentage (49.29 ± 6.98% vs. 46.75 ± 8.56%, triglyceride levels (116.58 ± 46.50 mg/dL vs. 101.19 ± 43.08 mg/dL, diastolic blood pressure (75.81 ± 8.08 mmHg vs. 71.19 ± 6.34 mmHg, and the number of risk factors for metabolic syndrome (2.00 ± 1.06 vs. 1.58 ± 1.10. Adolescents from the IG who gained/maintained weight reported reduced body fat percentage (48.81 ± 5.04% vs. 46.60 ± 5.53%, systolic blood pressure (123.39 ± 14.58 mmHg vs. 115.83 ± 7.02 mmHg, diastolic blood pressure (74.83 ± 9.91 mmHg vs. 68.78 ± 5.95 mmHg, and number of risk factors for metabolic syndrome (from 1.67 ± 1.09 to 1.11 ± 0.68, and their lean mass (39.00 ± 7.20 kg vs. 41.85 ± 7.53 kg and maximal oxygen uptake (23.74 ± 4.40 mL/kg/minute vs. 25.29 ± 5.17 mL/kg/minute increased in a manner similar to those of adolescents who lost weight. Furthermore, we noted significant decreases in body mass index, body fat (kg, glycemia, and waist circumference in CG adolescents who lost weight, whereas those in the CG who maintained/gained weight had an increase in body mass index, hip circumference, body fat (kg, and lean mass.

Within the next decades, nuclear safety and repository research will continue to be a necessary and integral constituent of the society's provident research. Yet, it is very difficult to maintain this competence in a politically complex environment with the scarce funds available. For its purpose, the Federal Government has appointed an evaluation commission, the chairmanship of which lies with the Federal Ministry of Economics and Technology. In its report of January 2001, the commission emphasised that efforts to adequately maintain competence in nuclear engineering, including industry-independent expert knowledge, will only meet with success, if the Federal Republic of Germany and the federal states contribute to a sufficient and stable financing of non-university research.

- Facebook (Menlo Park, California) is one of many online sites that provide potential educational tools for pathologists. We have each founded Facebook groups dedicated to anatomic pathology, in which members can share cases, ask questions, and contribute to discussions. - To report our experiences in founding and maintaining these Facebook groups and to characterize the contributed content. - We circulated a survey among the group founders, then compiled and analyzed the responses. - The groups varied in membership and in the quality of member contribution. Most posts were of pathology cases, although other topics (such as research articles) were also shared. All groups remained active and received posts from users all over the world, although all groups had many noncontributing members and received unwanted messages (which were screened and removed). Most founders were glad they had founded the groups because they provided an opportunity to both teach and learn. - Each analyzed Facebook group had a different character, and some downsides exist, but the groups all provided a no-cost way for pathologists and others across the world to interact online with many colleagues.

The intergroup protocols: Scalable group communication for the internet

Berket, Karlo [Univ. of California, Santa Barbara, CA (United States)

Reliable group ordered delivery of multicast messages in a distributed system is a useful service that simplifies the programming of distributed applications. Such a service helps to maintain the consistency of replicated information and to coordinate the activities of the various processes. With the increasing popularity of the Internet, there is an increasing interest in scaling the protocols that provide this service to the environment of the Internet. The InterGroup protocol suite, described in this dissertation, provides such a service, and is intended for the environment of the Internet with scalability to large numbers of nodes and high latency links. The InterGroup protocols approach the scalability problem from various directions. They redefine the meaning of group membership, allow voluntary membership changes, add a receiver-oriented selection of delivery guarantees that permits heterogeneity of the receiver set, and provide a scalable reliability service. The InterGroup system comprises several components, executing at various sites within the system. Each component provides part of the services necessary to implement a group communication system for the wide-area. The components can be categorized as: (1) control hierarchy, (2) reliable multicast, (3) message distribution and delivery, and (4) process group membership. We have implemented a prototype of the InterGroup protocols in Java, and have tested the system performance in both local-area and wide-area networks.

[Maintaining solidarity: is mutuality the solution?].

Science.gov (United States)

Gevers, J K M; Ploem, M C

2013-01-01

Solidarity is essentially the willingness to contribute to the community and its demands, which may even involve contributing more than one is expecting to receive. Another principle is mutuality: this refers to a balance between rights and obligations or between mutual obligations. In its advisory document 'The importance of mutuality......solidarity takes work!', The Dutch Council for Public Health and Health Care underlines the importance of ensuring solidarity within the Dutch health care system, e.g. by encouraging patients to take responsibility for their own health, possibly by introducing elements of mutuality. In our contribution, we comment on the Council's advice. Although we fully agree with the overall conclusion that solidarity should be maintained within the system, we do not see how the introduction of increased mutuality will contribute to this goal.

Every organism possesses a mechanism for maintaining homeostasis. We have focused on the immune system as a system that helps maintain homeostasis of the body, and particularly on the intestine as the largest organ of immunity in the body. We have also focused our research on the mechanism that responds to foreign substances in the intestine, especially the toll-like receptors (TLR). The activation of myeloid differentiation primary response gene 88 (MyD88) signal transduction as a response to TLR in the intestine is believed to contribute to the maintenance of homeostasis of the body through the homeostasis of the intestine. Furthermore, significant findings were reported in which signal transduction from TLR4 was essential for the maintenance and regulation of the intestine. These results strongly suggest the possibility that homeostasis in the intestine is maintained by TLR4, and signaling by TLR4 after exposure to lipopolysaccharide (LPS) probably has a role in regulating homeostasis. It is expected that the prevention and treatment of various diseases using TLR4 will continue to develop. As LPS is a substance that enhances the activity of TLR4, it will also attract attention as a valuable substance in its own right.

Effects of L-methamphetamine treatment on cocaine- and food-maintained behavior in rhesus monkeys.

Monoamine releasers with prominent dopaminergic actions, e.g., D-methamphetamine (D-MA), significantly reduce cocaine use and craving in clinical and preclinical laboratory studies. However, D-MA and related drugs also display high abuse potential, which limits their acceptability as agonist replacement medications for the management of Cocaine Use Disorder. The L-isomer of methamphetamine (L-MA), unlike D-MA, has preferential noradrenergic actions and is used medicinally with low, if any, abuse liability. The present study was conducted to determine whether L-MA could serve as an agonist replacement medication by both mimicking interoceptive effects of cocaine and decreasing intravenous (IV) cocaine self-administration. Separate groups (N = 4-5) of rhesus monkeys were studied to determine whether L-MA could (1) substitute for cocaine in subjects that discriminated intramuscular (IM) cocaine (0.4 mg/kg) from saline and (2) decrease IV cocaine self-administration under a second-order FR2(VR16:S) schedule of reinforcement. L-MA, like D-MA but with approximately 5-fold lesser potency, substituted for cocaine in drug discrimination experiments in a dose-dependent manner. In IV self-administration studies, 5-10-day treatments with continuously infused L-MA (0.032-0.32 mg/kg/h, IV) dose-dependently decreased cocaine-maintained responding; the highest dosage reduced cocaine intake to levels of saline self-administration without appreciable effects on food-maintained responding. These results indicate that L-MA both shares discriminative stimulus effects with cocaine and reduces cocaine self-administration in a behaviorally selective manner. L-MA and other compounds with a similar pharmacological profile deserve further evaluation for the management of Cocaine Use Disorder.

Full Text Available The Triticum timopheevi cytoplasmic male sterility (cms system in triticale (xTriticosecale Wittmack suffers from a low frequency of maintainers and environmental instability of the male sterility. On the other hand, the Pampa cms system in rye (Secale cereale exhibits strong male sterility and a low frequency of restorers. Here, we report generating hybrids between maintainers of the T. timopheevi cms system in triticale and maintainers of the rye Pampa cms system. Ten hybrids were obtained. Their hybridity was verified by PCR (polymerase chain reaction using ISSR (inter simple sequence repeats primers. The cms maintaining ability of F2 individuals and their progeny was tested. The F2 plants were crossed to male sterile lines of triticale carrying the T. timopheevi cytoplasm. Among 180 G1 offspring of these crosses, 71 (39.4% were completely male sterile. Fourteen F2 individuals (7.8%, as well as their F2S1 and progeny, generated stable male sterility in G1, G1BC1 and G1BC2 generations after the crosses. Our results suggest that it is possible to produce a more stable cms system in triticale based on the T. timopheevi cytoplasm as compared to the existing one.

Preschoolers' group bias in punishing selfishness in the Ultimatum Game.

Wu, Zhen; Gao, Xiaohe

Previous studies have shown that both adults and children tend to favor members of their own group and expect reciprocity of such in-group privilege. If a person is treated unfairly by an in-group member, a conflict arises between the tendency of in-group favoritism and the desire to punish violators of in-group norms. How do children solve the conflict at different points in development? We compared how preschoolers punished in-group and out-group members (marked by color preference) for selfishness in the Ultimatum Game. We found that (a) 3- to 6-year-old Chinese children rejected selfish allocations more often than fair ones, showing a robust preference for fairness; (b) 3- and 4-year-olds showed no group differences in their punishment behavior, suggesting that second-party punishment of selfishness is not biased during early childhood; (c) 5- and 6-year-old girls were more likely to punish selfishness of in-groups than of out-groups, illuminating an early sign of maintaining group-based fairness norms even at a personal cost; and (d) 5- and 6-year-old boys, however, punished in-groups and out-groups equally often and punished out-groups more often than did girls. These age and gender differences in children's punishment imply that socialization may play an important role in showing group bias when enforcing fairness norms. Copyright © 2017 Elsevier Inc.

Sustained levels of FGF2 maintain undifferentiated stem cell cultures with biweekly feeding.

Directory of Open Access Journals (Sweden)

Steven Lotz

Full Text Available An essential aspect of stem cell culture is the successful maintenance of the undifferentiated state. Many types of stem cells are FGF2 dependent, and pluripotent stem cells are maintained by replacing FGF2-containing media daily, while tissue-specific stem cells are typically fed every 3rd day. Frequent feeding, however, results in significant variation in growth factor levels due to FGF2 instability, which limits effective maintenance due to spontaneous differentiation. We report that stabilization of FGF2 levels using controlled release PLGA microspheres improves expression of stem cell markers, increases stem cell numbers and decreases spontaneous differentiation. The controlled release FGF2 additive reduces the frequency of media changes needed to maintain stem cell cultures, so that human embryonic stem cells and induced pluripotent stem cells can be maintained successfully with biweekly feedings.

Dovis, Vonyca; Setyowati; Kurniawati, Wiwit

Young women face a difficult situation when they live in a prostitution area or red light district. A phenomenological approach was applied to explore the experiences in maintaining reproductive health of 10 young women living in the prostitution area in Lampung, one of the provinces in Sumatra. Thematic content analysis found 7 themes including: (1) The participants' perception of prostitution as a place of naughty women and free sexual activity that can transmit STDs and influence adolescent psychology; (2) The ways the participants kept their reproductive organs healthy were through maintaining friendships, maintaining personal hygiene, avoiding free sexual activity, eating healthy food, and having routine medical checkups; (3) Information support was gained from family, health workers, media, and teachers; (4) Emotional support from family and friends; (5) Barriers to maintaining good health were inaccessible health facilities and an underfunded health service; (6) The needs of the participants were reproductive health services and clean environment; (7) The participants hoped for health education and intensive health services with friendly nurses. The results of this research illustrate that there is a need for socializing intensive ways to maintain reproductive health, especially in a risky environment.

Despite the best efforts in prevention, premature loss of primary teeth continues to be a common problem in pediatric dentistry, resulting in disruption of arch integrity and adversely affecting the proper alignment of permanent successors. Space maintainers (SMs) are special appliances used for maintaining space created due to premature loss of primary teeth. Band and loop SM is mostly indicated for the premature loss of single primary molar, but this appliance has a number of limitations both for operators and for patients. Presented in this article is an innovative "Tube and Loop" SM (Nikhil appliance) which offers several advantages over the conventional band and loop SM. It is not only easy and quick to fabricate but can also be completed in a single sitting and cumbersome steps like impression making and laboratory procedures namely soldering are eliminated.

The U.S. Department of Energy (DOE) Office of Legacy Management (LM) is an integral part of DOE's strategy to ensure that legacy liabilities of former nuclear weapons production sites are properly managed following the completion of environmental cleanup activities. In the area of environmental legacy management, records management is crucial to the protection of health, environmental, and legal interests of the Department and the public. LM is responsible for maintaining long-term surveillance and maintenance (LTS and M) records in performance of its mission. Maintaining access to the knowledge contained in these record collections is one of LM's primary responsibilities. To fulfill this responsibility, LM established a consolidated records management facility, the LM Business Center (LMBC), to house physical media records and electronic records. A new electronic record keeping system (ERKS) was needed to replace an obsolete system while helping to ensure LM is able to meet ongoing responsibilities to maintain access to knowledge and control the life cycle management of records.

Embryonic stem (ES) cells maintain pluripotency by self-renewal. Several homeoproteins, including Oct3/4 and Nanog, are known to be key factors in maintaining the self-renewal capacity of ES cells. However, other genes required for the mechanisms underlying this process are still unclear. Here we report the identification by in silico analysis of a homeobox-containing gene, CrxOS, that is specifically expressed in murine ES cells and is essential for their self-renewal. ES cells mainly express the short isoform of endogenous CrxOS. Using a polyoma-based episomal expression system, we demonstrate that overexpression of the CrxOS short isoform is sufficient for maintaining the undifferentiated morphology of ES cells and stimulating their proliferation. Finally, using RNA interference, we show that CrxOS is essential for the self-renewal of ES cells, and provisionally identify foxD3 as a downstream target gene of CrxOS. To our knowledge, ours is the first delineation of the physiological role of CrxOS in ES cells.

Fluctuating survival selection explains variation in avian group size.

2016-05-03

Most animal groups vary extensively in size. Because individuals in certain sizes of groups often have higher apparent fitness than those in other groups, why wide group size variation persists in most populations remains unexplained. We used a 30-y mark-recapture study of colonially breeding cliff swallows (Petrochelidon pyrrhonota) to show that the survival advantages of different colony sizes fluctuated among years. Colony size was under both stabilizing and directional selection in different years, and reversals in the sign of directional selection regularly occurred. Directional selection was predicted in part by drought conditions: birds in larger colonies tended to be favored in cooler and wetter years, and birds in smaller colonies in hotter and drier years. Oscillating selection on colony size likely reflected annual differences in food availability and the consequent importance of information transfer, and/or the level of ectoparasitism, with the net benefit of sociality varying under these different conditions. Averaged across years, there was no net directional change in selection on colony size. The wide range in cliff swallow group size is probably maintained by fluctuating survival selection and represents the first case, to our knowledge, in which fitness advantages of different group sizes regularly oscillate over time in a natural vertebrate population.

No effective pharmacotherapies exist for cocaine dependence, although contingency management (CM) has demonstrated efficacy. To compare the efficacy of bupropion hydrochloride and CM for reducing cocaine use in methadone hydrochloride-maintained individuals. This 25-week, placebo-controlled, double-blind trial randomly assigned participants to 1 of 4 treatment conditions: CM and placebo (CMP), CM and 300 mg/d of bupropion hydrochloride (CMB), voucher control and placebo (VCP), or voucher control and bupropion (VCB). Outpatient clinic at the Veterans Affairs Connecticut Healthcare System. A total of 106 opiate-dependent, cocaine-abusing individuals. All study participants received methadone hydrochloride (range, 60-120 mg). Participants receiving bupropion hydrochloride were given 300 mg/d beginning at week 3. In the CM conditions, each urine sample negative for both opioids and cocaine resulted in a monetary-based voucher that increased for consecutively drug-free urine samples during weeks 1 to 13. Completion of abstinence-related activities also resulted in a voucher. During weeks 14 to 25, only completion of activities was reinforced in the CM group, regardless of sample results. The voucher control groups received vouchers for submitting urine samples, regardless of results, throughout the study. Thrice-weekly urine toxicologic test results for cocaine and heroin. Groups did not differ in baseline characteristics or retention rates. Opiate use decreased significantly, with all treatment groups attaining equivalent amounts of opiate use at the end of the study. In the CMB group, the proportion of cocaine-positive samples significantly decreased during weeks 3 to 13 (P<.001) relative to week 3 and remained low during weeks 14 to 25. In the CMP group, cocaine use significantly increased during weeks 3 to 13 (P<.001) relative to week 3, but then cocaine use significantly decreased relative to the initial slope during weeks 14 to 25 (P<.001).

The Role of Leptin in Maintaining Plasma Glucose During Starvation.

Perry, Rachel J; Shulman, Gerald I

2018-03-01

For 20 years it has been known that concentrations of leptin, a hormone produced by the white adipose tissue (WAT) largely in proportion to body fat, drops precipitously with starvation, particularly in lean humans and animals. The role of leptin to suppress the thyroid and reproductive axes during a prolonged fast has been well defined; however, the impact of leptin on metabolic regulation has been incompletely understood. However emerging evidence suggests that, in starvation, hypoleptinemia increases activity of the hypothalamic-pituitary-adrenal axis, promoting WAT lipolysis, increasing hepatic acetyl-CoA concentrations, and maintaining euglycemia. In addition, leptin may be largely responsible for mediating a shift from a reliance upon glucose metabolism (absorption and glycogenolysis) to fat metabolism (lipolysis increasing gluconeogenesis) which preserves substrates for the brain, heart, and other critical organs. In this way a leptin-mediated glucose-fatty acid cycle appears to maintain glycemia and permit survival in starvation.

Local neutral networks help maintain inaccurately replicating ribozymes.

The error threshold of replication limits the selectively maintainable genome size against recurrent deleterious mutations for most fitness landscapes. In the context of RNA replication a distinction between the genotypic and the phenotypic error threshold has been made; where the latter concerns the maintenance of secondary structure rather than sequence. RNA secondary structure is treated as a proxy for function. The phenotypic error threshold allows higher per digit mutation rates than its genotypic counterpart, and is known to increase with the frequency of neutral mutations in sequence space. Here we show that the degree of neutrality, i.e. the frequency of nearest-neighbour (one-step) neutral mutants is a remarkably accurate proxy for the overall frequency of such mutants in an experimentally verifiable formula for the phenotypic error threshold; this we achieve by the full numerical solution for the concentration of all sequences in mutation-selection balance up to length 16. We reinforce our previous result that currently known ribozymes could be selectively maintained by the accuracy known from the best available polymerase ribozymes. Furthermore, we show that in silico stabilizing selection can increase the mutational robustness of ribozymes due to the fact that they were produced by artificial directional selection in the first place. Our finding offers a better understanding of the error threshold and provides further insight into the plausibility of an ancient RNA world.

Rimonabant has been shown to reduce weight, free androgen index (FAI) and insulin resistance in obese patients with polycystic ovary syndrome (PCOS) compared to metformin. Studies have shown that significant weight regain occurs following the cessation of rimonabant therapy. This study was undertaken to determine if subsequent metformin treatment after rimonabant would maintain the improvement in weight, insulin resistance and hyperandrogenaemia in PCOS. An extension study for 3 months with the addition of metformin to the randomised open labelled parallel study of metformin and rimonabant in 20 patients with PCOS with a body mass index >or= 30 kg/m(2). Patients who were on 3 months of rimonabant were changed over to metformin for 3 months, whereas those on 3 months of metformin were continued on metformin for another 3 months. The primary end-point was a change in weight; secondary end-points were a change in FAI and insulin resistance. The mean weight loss of 6.2 kg associated with 3 months of rimonabant treatment was maintained by 3 months of metformin treatment (mean change +0.2 kg, P = 0.96). Therefore, the percentage reduction in weight remained significantly higher in the rimonabant/metformin group compared to metformin only subjects at 6 months compared to baseline (-6.0 +/- 0.1%vs. -2.8 +/- 0.1%, P = 0.04). The percentage change in testosterone and FAI from baseline to 6 months was also greater in the rimonabant/metformin group. [Testosterone (-45.0 +/- 5.0%vs. -16 +/- 2.0%, P = 0.02); FAI (-53.0 +/- 5.0%vs. -17.0 +/- 12.2%, P = 0.02)]. HOMA-IR continued to fall significantly in the rimonabant/metformin group between 0, 3 and 6 months (4.4 +/- 0.5 vs. 3.4 +/- 0.4 vs. 2.7 +/- 0.3, respectively, P weight loss and enhanced the metabolic and biochemical parameters achieved by treatment with rimonabant, compared to 6 months of metformin treatment alone.

The purpose of this study was to evaluate the significance of our dental management protocol by observing the chronological change of dental health of head and neck radiotherapy patients. Fifty-two head and neck radiotherapy patients who had received dental management to prevent and/or alleviate their oral complications were enrolled in this study. They were followed for three or more years after radiotherapy. We divided them into three groups according to the timing of the start of dental management; Pre, Mid and Post. The chronological changes of dental status (DMFT and the number of tooth extractions) and osteoradionecrosis were investigated for three to five years. The increase in the DMFT index of the Pre and Mid groups was reduced to less than 2 by introducing our dental management protocol. On the contrary, the number of unavoidable tooth extractions following radiotherapy was the least in the Pre group. The incidence rates of osteoradionecrosis of the mandible in the Pre, Mid and Post groups were 6.5%, 18.0% and 20.0% respectively. Our dental management protocol was proved to be effective in maintaining dental health and helpful in controlling osteoradionecrosis following head and neck radiotherapy. For a more effective outcome, we advocate that dental management should commence before the start of head and neck radiotherapy. (author)

Maintaining Students’ Involvement in a Math Lecture Using Countdown Timers

2015-12-01

Full Text Available Involving students in a lecture is an important but not an easy task that every lecturer must encourage. This task becomes even greater in a math class that is composed of eighty to a hundred sixty students. In 2007, the University of the Philippines Los Baños (UPLB started offering some of its basic math courses in lecture-recitation set-up. This shift and many other factors drove most math instructors of UPLB to widely use presentation software, such as the PowerPoint (PPT, to deliver their lectures. The non-stop use of these softwares, however, seems to have negative effects on the students when it comes to maintaining their involvement in a lecture discussion for they tend to be more passive spectators. On the other hand, adding countdown timers strategically on some parts of the discussion seems to lessen such negative effects. This study determined the effectiveness of using countdown timers in maintaining students’ involvement in a lecture of MATH 27 (Analytic Geometry and Calculus II, a course in UPLB commonly taken by sophomore students. Results show that the effectiveness of countdown timers, as perceived by the students, is independent to students’ genders and degree programs, but is dependent to the colleges where the students belong to. Also, some effects of countdown timers are significantly correlated to various data from students’ profiles. It was concluded in the study that the use of countdown timers is effective in maintaining student’s involvement in MATH 27 lectures and might also be useful in other math lecture classes

Maintaining access to safe abortion and reducing sex ratio imbalances in Asia.

Science.gov (United States)

Ganatra, Bela

2008-05-01

High sex ratios at birth (108 boys to 100 girls or higher) are seen in China, Taiwan, South Korea and parts of India and Viet Nam. The imbalance is the result of son preference, accentuated by declining fertility. Prenatal sex detection with ultrasound followed by second trimester abortion is one of the ways sex selection manifests itself, but it is not the causative factor. Advocates and governments seeking to reverse this imbalance have largely prohibited sex detection tests and/or sex selective abortion, assuming these measures would reverse the trend. Such policies have been difficult to enforce and have met with only limited success. At the same time, such policies are starting to have adverse effects on the already limited access to safe and legal second trimester abortion for reasons other than sex selection. Moreover, the sex selection issue is being used as a platform for anti-abortion rhetoric by certain groups. Maintaining access to safe abortion and achieving a decline in high sex ratios are both important goals. Both are possible if the focus shifts to addressing the conditions that drive son preference.

The propaganda of extreme hostility: denunciation and the regulation of the group.

Finlay, W M L

2007-06-01

This paper discusses how those espousing racist or separatist ideologies seek to persuade others to conform to their beliefs. Using examples from Nazi Germany, White Power movements in the USA and the extreme fringes of Zionist politics, it illustrates how notions of identity are linked to positions of hostility, hatred or separatism from other groups. In particular, it describes how those who maintain relations with other groups or who oppose hostility are discounted through accounts of social influence. The effectiveness of this rhetoric in terms of creating climates of social and self-censure, and of silencing dissent in situations of conflict, is discussed.

Full Text Available This study explored why and how Russian speaking parents in an Irish context maintained the Russian language in their school-age children. Using a self-administered unstandardised questionnaire, the opinions of 16 Russian-speaking parents, reporting on 24 children, were surveyed. Of this sample, five parents were then interviewed using focus group methodology. The main findings revealed that Russian-speaking parents living in Ireland strongly supported Russian language maintenance in their families and wanted their children to be as fluent as possible in the Russian language. The reasons for the support of Russian language were: cultural preservation, general knowledge of languages in addition to English, and communication with the homeland. Methods employed to maintain the Russian language included conversing with children through Russian, reading and watching Russian TV/DVD. Although most parents spoke only Russian to their children, just three children were considered by their parents to have sufficient language skills to interact through Russian in Russian speaking countries. Interestingly, 15 children were thought to have adequate skills in Russian to speak with those outside their immediate family when in Ireland. Congruent with other studies of bilingualism, development of English, or the secondary, majority language, was also important to parents, as they lived in a dominant English-speaking society.

This article discusses the results of a study made by the 'ProKlimA' project group on the various factors that contribute to the so-called 'Sick Building Syndrome'. This study, made between 1994 and 2000, was initiated by the suspicion cast on ventilation and air-conditioning systems as being the cause of irritations to the skin, eyes, nose, mouth and throat, headaches and general uneasiness. An overview of the results of the study made at a total of 4,592 workplaces in 14 office buildings is given that cover physical, technical, chemical, biological, psychological and medicinal aspects of the problem. Air-quality aspects are examined and psychosocial factors - that had a higher level of influence than expected - are discussed. The author stresses the importance of the findings that confirm that a well-maintained air-conditioning system that conforms to modern hygiene standards attains a better subjective rating and that workplace design and good personnel motivation play a very important role in avoiding the 'Sick Building Syndrome'.

The collaboration of grouping laws in vision.

Science.gov (United States)

Grompone von Gioi, Rafael; Delon, Julie; Morel, Jean-Michel

2012-01-01

Gestalt theory gives a list of geometric grouping laws that could in principle give a complete account of human image perception. Based on an extensive thesaurus of clever graphical images, this theory discusses how grouping laws collaborate, and conflict toward a global image understanding. Unfortunately, as shown in the bibliographical analysis herewith, the attempts to formalize the grouping laws in computer vision and psychophysics have at best succeeded to compute individual partial structures (or partial gestalts), such as alignments or symmetries. Nevertheless, we show here that a never formalized clever Gestalt experimental procedure, the Nachzeichnung suggests a numerical set up to implement and test the collaboration of partial gestalts. The new computational procedure proposed here analyzes a digital image, and performs a numerical simulation that we call Nachtanz or Gestaltic dance. In this dance, the analyzed digital image is gradually deformed in a random way, but maintaining the detected partial gestalts. The resulting dancing images should be perceptually indistinguishable if and only if the grouping process was complete. Like the Nachzeichnung, the Nachtanz permits a visual exploration of the degrees of freedom still available to a figure after all partial groups (or gestalts) have been detected. In the new proposed procedure, instead of drawing themselves, subjects will be shown samples of the automatic Gestalt dances and required to evaluate if the figures are similar. Several numerical preliminary results with this new Gestaltic experimental setup are thoroughly discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Youth Armed Groups in Colombia

Directory of Open Access Journals (Sweden)

Linda Dale

2014-09-01

Full Text Available For the many years of Colombia’s civil war, youth have been trying to find their way in complicated and dangerous situations. A central component of this is their relationship with armed groups, something that has evolved considerably over the past ten years. This practice note examines the context within which these connections are formed and the implications this has for self/social identity and meaningful resistance. The ideas in this practice note are based on consultations with young Colombians, particularly those displaced from 2000-2013. These sessions included art activities, focus groups and individual interviews. Art activities involved descriptive and expressive projects so that participants could explore their feelings and memories of situations and experiences. This provided a base for group discussions where youth exchanged information and debated issues. A total of 34 workshops were held over a twelve year period. These consultations revealed how war flows all over young people, touching every aspect of their identity. The boundaries between the personal and political no longer exist in today’s civil wars, if indeed they every truly did. Young people growing up inside Colombia’s war understand this at a deep level. An acknowledgement of this pain – showing the connections between the personal and political dimensions of war – is, they would maintain, the basis for their personal healing as well as an important tool for the building of sustainable peace.

The impact of instructor grouping strategies on student efficacy in inquiry science labs: A phenomenological case study of grouping perceptions and strategies

Science.gov (United States)

Miller, Nathaniel J.

Abundant educational research has integrated Albert Bandura's concepts of self-efficacy and collective efficacy within educational settings. In this phenomenological case study, the investigation sought to capture the manifestation of self-efficacy and collective efficacy within inquiry-based science laboratory courses. Qualitative data was derived from student efficacy surveys, direct classroom observations, and three-tiered interviews with teacher participants. Four high school science instructors and their students from two school districts in Northern Illinois were selected to participate in the study. This study sought to identify instructor strategies or criteria used to formulate student laboratory groups and the impact of such groupings on student self-efficacy and collective efficacy. Open coding of interview transcripts, observation logs, and student surveys led to the development of eight emerging themes. These themes included the purpose of science laboratory activities, instructor grouping strategies, instructor roles, instructor's perceptions, science laboratory assessment, student interactions, learner self-perceptions, and grouping preferences. Results from the study suggest that some students were innately inclined to assume leadership roles, smaller groupings had greater participation from all group members, students had a strong preference for working collaboratively in groups, and students desired to maintain stable laboratory groups in lieu of periodically changing laboratory partners. As with all case study methodologies, the findings of the study were limited to the individual participants at research sites and were not generalizable to all science classrooms. Additional research in the realms of group size, group autonomy, and student interviews would provide even greater insights into the observed phenomena.

2005-01-01

Cancer support groups are an important source of support for cancer patients, yet little is known about the characteristics of, and barriers to, effective leadership, and the training needs of both professionally trained and untrained leaders. This study explored the views of 179 leaders of 184 cancer support groups in NSW, Australia, regarding these issues. Four hundred and sixteen members of 50 groups selected from the larger cohort completed questionnaires eliciting the importance of group processes, including leader qualities, and satisfaction with group leadership. Finally, members of nine groups participated in focus groups regarding effective group processes. The importance of the leader(s) was emphasized in all stages of the research. Fifty-nine percent of group leaders were currently experiencing a difficulty, primarily related to infrastructure or group process. Three characteristics of effective leaders were identified: educational qualities, facilitation skills, and personal qualities. There is clearly a need to develop and evaluate effective interventions to maintain leaders in these roles, if the proven benefits for cancer patients are to be protected.

The Challenges of Maintaining Nuclear Cultures. US and UK Perspectives

International Nuclear Information System (INIS)

Brooks, Linton; McKane, Tom

2016-01-01

After the world entered the nuclear age, civilian and military organizations have witnessed the slow emergence of nuclear cultures, defined as the set of values and knowledge, shared among the national security community, about the relative importance of nuclear weapons in the country's defense posture, the distinctive features of nuclear weapons in terms of security, safety and operational requirements, and the workings of deterrence. Nuclear cultures have helped to ensure some level of coherence in policy-making and, most importantly, to maintain safe and effective deterrents. At a national level, however, each nuclear culture is confronted with significant challenges, such as generational change, decreasing levels of understanding or attention among the political and military leadership, insufficient funding or a growing inability to meet manpower requirements in both the nuclear weapons complexes and the armed forces. This paper looks at the United States and United Kingdom's recent efforts to maintain their nuclear culture, and at the key challenges these two countries face while pursuing this aim. (authors)

Full Text Available ish fillet is one of fisheries products that easily deteriorated; hence handling techniques are needed to maintain the freshness. Ultrasonic wave have been widely applied to some of food products for maintaining freshness through microbial inactivation, however the ultrasonic application to fisheries products has not been reported. The purpose of this study was to analyze the effect of ultrasonic wave on fish freshness. The stages of the study were sample preparation, sonication, freshness parameters examination and histology observation. Ultrasonic wave did not affectthe organoleptic value and the TVB, but affected the pH value and the TPC. The sample in which the TPC value was found significantly different, were further observed after 48 and 96 hours storage. The result showed that the TPC value of sonicated sample for 9 minutes was lower to that of without sonication. Histology analysis showed, however, sonication made the structure of muscle fiber less compact and deformation of myomer was found.

Fermented milk products containing Bifidobacterium breve strain Yakult (BFM) may improve clinical status in ulcerative colitis (UC) patients. To assess efficacy of BFM in maintaining remission in Japanese patients with quiescent UC. This double-blind study (B-FLORA) enrolled 195 patients with quiescent UC, randomized to receive one pack of BFM fermented milk per day [Bifidobacterium breve strain Yakult (10 billion bacteria) and Lactobacillus acidophilus (1 billion bacteria)] (n = 98) or matching placebo (n = 97) for 48 weeks. The primary efficacy endpoint was relapse-free survival (relapse: rectal bleeding score ≥ 2 on Sutherland disease activity index scale for 3 consecutive days and/or initiation of remission induction therapy for worsening of UC). An interim analysis was conducted after inclusion and follow-up of one-third of patients for the first phase of the study (n = 195). Relapse-free survival was not significantly different between the BFM and placebo groups (P = 0.643; hazard ratio 1.16; 95% CI 0.63-2.14, log-rank test), nor was the incidence of relapse. Therefore, the study was discontinued for lack of efficacy. An exploratory analysis of fecal samples from a subgroup of patients revealed no effects of either study beverage on intestinal microbiota, but there was a significant decrease in Bifidobacterium species before relapse, regardless of treatment group. Three mild adverse events occurred for which a causal relationship with the study beverage could not be ruled out (placebo: abdominal bloating and stress in one patient; BFM: body odor in one patient). BFM had no effect on time to relapse in UC patients compared with placebo. UMIN000007593.

2016-04-01

Contemporary emphasis on creating culturally relevant and context specific knowledge increasingly drives researchers to conduct their work in settings outside their home country. This often requires researchers to build relationships with various stakeholders who may have a vested interest in the research. This case study examines the tension between relationship development with stakeholders and maintaining study integrity, in the context of potential harms, data credibility and cultural sensitivity. We describe an ethical breach in the conduct of global health research by a arising from the ad-hoc participation of a community stakeholder external to the visiting research group. A framework for reflection is developed from a careful examination of underlying factors and presented with a discussion of consequences and mitigation measures. This framework aims to present lessons learned for researchers working abroad who might face similar situations in their work. © 2015 John Wiley & Sons Ltd.

The European region, certified as polio free in 2002, had recent wild poliovirus (WPV) introductions, resulting in a major outbreak in Central Asian countries and Russia in 2010 and in current widespread WPV type 1 circulation in Israel, which endangered the polio-free status of the region. We assessed the data on the major determinants of poliovirus transmission risk (population immunity, surveillance, and outbreak preparedness) and reviewed current threats and measures implemented in response to recent WPV introductions. Despite high regional vaccination coverage and functioning surveillance, several countries in the region are at high or intermediate risk of poliovirus transmission. Coverage remains suboptimal in some countries, subnational geographic areas, and population groups, and surveillance (acute flaccid paralysis, enterovirus, and environmental) needs further strengthening. Supplementary immunization activities, which were instrumental in the rapid interruption of WPV1 circulation in 2010, should be implemented in high-risk countries to close population immunity gaps. National polio outbreak preparedness plans need strengthening. Immunization efforts to interrupt WPV transmission in Israel should continue. The European region has successfully maintained its polio-free status since 2002, but numerous challenges remain. Staying polio free will require continued coordinated efforts, political commitment and financial support from all countries.

Concerns regarding increasing health care costs, health care provider availability, dissatisfaction with wait times, and the minimal opportunity for education and support associated with the individual care model have given rise to interest in alternative models of prenatal care. One alternative model, group prenatal care, may be beneficial or preferred for some practice settings and patient populations, although individual prenatal care remains standard practice. Group prenatal care models are designed to improve patient education and include opportunities for social support while maintaining the risk screening and physical assessment of individual prenatal care. Bringing patients with similar needs together for health care encounters increases the time available for the educational component of the encounter, improves efficiency, and reduces repetition. Evidence suggests patients have better prenatal knowledge, feel more ready for labor and delivery, are more satisfied with care in prenatal care groups, and initiate breastfeeding more often. There is no evidence that suggests that group prenatal care causes harm. Individual and group care models warrant additional study with a goal of demonstrating differences in outcomes and identifying populations that benefit most from specific care models.

Distinct Neural Substrates for Maintaining Locations and Spatial Relations in Working Memory

Directory of Open Access Journals (Sweden)

Kara J Blacker

2016-11-01

Full Text Available Previous work has demonstrated a distinction between maintenance of two types of spatial information in working memory (WM: spatial locations and spatial relations. While a body of work has investigated the neural mechanisms of sensory-based information like spatial locations, little is known about how spatial relations are maintained in WM. In two experiments, we used fMRI to investigate the involvement of early visual cortex in the maintenance of spatial relations in WM. In both experiments, we found less quadrant-specific BOLD activity in visual cortex when a single spatial relation, compared to a single spatial location, was held in WM. Also across both experiments, we found a consistent set of brain regions that were differentially activated during maintenance of locations versus relations. Maintaining a location, compared to a relation, was associated with greater activity in typical spatial WM regions like posterior parietal cortex and prefrontal regions. Whereas maintaining a relation, compared to a location, was associated with greater activity in the parahippocampal gyrus and precuneus/retrosplenial cortex. Further, in Experiment 2 we manipulated WM load and included trials where participants had to maintain three spatial locations or relations. Under this high load condition, the regions sensitive to locations versus relations were somewhat different than under low load. We also identified regions that were sensitive to load specifically for location or relation maintenance, as well as overlapping regions sensitive to load more generally. These results suggest that the neural substrates underlying WM maintenance of spatial locations and relations are distinct from one another and that the neural representations of these distinct types of spatial information change with load.

Maintaining the design Integrity of nuclear installations throughout their operating life. INSAG-19. A report by the International Nuclear Safety Advisory Group (Russian Edition)

2015-01-01

A nuclear power plant design is the product of the activities of many organizations, and changes to that design will occur continuously over the plant's lifetime. Reactor plants are designed to operate for a long period of time, typically 40 years, which may be extended for several decades. This period of time spans several working lifetimes of the staff of the plant, and its length represents a very specific challenge to safety and to the corporate asset management of the enterprise. It also implies that the vendor structure required to support the plant can be expected to change substantially during the plant's lifetime. this INSAG report discusses the problem of maintaining the integrity of design of a nuclear power plant over its entire lifetime in order to achieve a continuous high level of safety.

Full Text Available Band materials are often used in the practice of pediatric dentistry. Nickel and Chromium are the main ingredients of these materials. The potential health hazards of nickel and chromium and their compounds have been the focus of attention for more than 100 years. It has established that these metals could cause hypersensitivity. The study was undertaken to analyze in vitro biodegradation of space maintainers made out of stainless steel band materials from manufacturers Dentaurum and Unitek. The leaching effect simulating the use of one, two, three, and four space maintainers in clinical practice was studied by keeping the respective number of space maintainers in the artificial saliva incubating at 37°C and analyzing for nickel and chromium release after 1,7,14,21 and 28 days using atomic absorption spectrophotometer. Results showed that there was measurable release of both nickel and chromium which reached maximum level at the end of 7 days which was statistically significant (P < 0.05 and was very much below the dietary average intake even for four bands used and was not capable of causing any toxicity.

Professional Development Strategies to Enhance Nurses' Knowledge and Maintain Safe Practice.

Bindon, Susan L

2017-08-01

Maintaining competence is a professional responsibility for nurses. Individual nurses are accountable for their practice, as outlined in the American Nurses Association's Nursing: Scope and Standards of Practice. Nurses across clinical settings face the sometimes daunting challenge of staying abreast of regulatory mandates, practice changes, equipment updates, and other workplace expectations. In the complex, evolving perioperative setting, professional development is a priority, and the need for ongoing education is critical. However, nurses' efforts to engage in their own development can be hampered by a lack of time, limited access to educational resources, or cost concerns. This article provides an overview of nursing professional development and offers some resources to help individual nurses maintain or enhance their knowledge, skills, and attitudes.

Warren, Timothy L; Weir, Peter T; Dickinson, Michael H

2018-05-11

Animals must use external cues to maintain a straight course over long distances. In this study, we investigated how the fruit fly Drosophila melanogaster selects and maintains a flight heading relative to the axis of linearly polarized light, a visual cue produced by the atmospheric scattering of sunlight. To track flies' headings over extended periods, we used a flight simulator that coupled the angular velocity of dorsally presented polarized light to the stroke amplitude difference of the animals' wings. In the simulator, most flies actively maintained a stable heading relative to the axis of polarized light for the duration of 15 min flights. We found that individuals selected arbitrary, unpredictable headings relative to the polarization axis, which demonstrates that D . melanogaster can perform proportional navigation using a polarized light pattern. When flies flew in two consecutive bouts separated by a 5 min gap, the two flight headings were correlated, suggesting individuals retain a memory of their chosen heading. We found that adding a polarized light pattern to a light intensity gradient enhanced flies' orientation ability, suggesting D . melanogaster use a combination of cues to navigate. For both polarized light and intensity cues, flies' capacity to maintain a stable heading gradually increased over several minutes from the onset of flight. Our findings are consistent with a model in which each individual initially orients haphazardly but then settles on a heading which is maintained via a self-reinforcing process. This may be a general dispersal strategy for animals with no target destination. © 2018. Published by The Company of Biologists Ltd.

Distributed Group-Based Mobility Management Scheme in Wireless Body Area Networks

Directory of Open Access Journals (Sweden)

Moneeb Gohar

2017-01-01

Full Text Available For group-based mobility management in 6LoWPAN-based wireless body area networks (WBAN, some schemes using the Proxy Mobile IPv6 (PMIP have been proposed. However, the existing PMIP-based mobility schemes tend to induce large registration delay and handover delay. To overcome such limitations, we propose a new distributed group-based mobility management scheme, in which the Local Mobility Anchor (LMA function is implemented by each Mobile Access Gateway (MAG and the handover operation is performed between two neighboring MAGs without the help of LMA. Besides, each MAG maintains the information of the group of mobile sensors and aggregates the Authentication-Authorization-Accounting (AAA query messages for a group of mobile sensors as a “single” message to decrease the control overhead. By numerical analysis, it is shown that the proposed scheme can reduce the registration and handover delays, compared to the existing PMIP-based mobility schemes.

Heartwarming memories: Nostalgia maintains physiological comfort.

Zhou, Xinyue; Wildschut, Tim; Sedikides, Constantine; Chen, Xiaoxi; Vingerhoets, Ad J J M

2012-08-01

Nostalgia, a sentimental longing or wistful affection for the past, is a predominantly positive and social emotion. Recent evidence suggests that nostalgia maintains psychological comfort. Here, we propose, and document in five methodologically diverse studies, a broader homeostatic function for nostalgia that also encompasses the maintenance of physiological comfort. We show that nostalgia--an emotion with a strong connotation of warmth--is triggered by coldness. Participants reported stronger nostalgia on colder (vs. warmer) days and in a cold (vs. neutral or warm) room. Nostalgia, in turn, modulates the interoceptive feeling of temperature. Higher levels of music-evoked nostalgia predicted increased physical warmth, and participants who recalled a nostalgic (vs. ordinary autobiographical) event perceived ambient temperature as higher. Finally, and consistent with the close central nervous system integration of temperature and pain sensations, participants who recalled a nostalgic (vs. ordinary autobiographical) event evinced greater tolerance to noxious cold.

Cognitive behavioural group treatment for social anxiety in schizophrenia.

Science.gov (United States)

Kingsep, Patrick; Nathan, Paula; Castle, David

2003-09-01

Anxiety symptoms reported by individuals with schizophrenia have been traditionally seen as symptoms associated with the principal disorder and therefore not requiring special attention. The primary aim of this paper is to therapeutically target social anxiety symptoms in individuals with schizophrenia in order to determine the effectiveness of the cognitive behavioural group treatment model as an intervention for social anxiety in this participant group. Thirty-three individuals with schizophrenia and co-morbid social anxiety were allocated to a group-based cognitive behaviour (CBGT) intervention or waitlist control (WLC). Baseline, completion and follow-up ratings consist of measures of social anxiety: the Brief Social Phobia Scale (BSPS), Brief Fear of Negative Evaluation scale (BFNE) and the Social Interaction Anxiety Scale (SIAS); measures of general psychopathology: the Calgary Depression Scale for Schizophrenia (CDSS) and Global Severity Index (GSI) from the Brief Symptom Inventory (BSI); and the Quality of Life, Enjoyment and Satisfaction Questionnaire (QLESQ). Pre- and post-treatment measures were subjected to statistical evaluation. All outcome measures displayed statistical improvement in the intervention group compared with no change in the control group. These treatment gains were maintained at follow-up. CBGT for social anxiety in schizophrenia was demonstrated to be effective as an adjunctive treatment for this population.

Dominance relationships among siamang males living in multimale groups.

Science.gov (United States)

Morino, Luca

2016-03-01

Intense intolerance among males is considered to be an important mechanism maintaining the uni-male organization traditionally attributed to socially monogamous gibbons. Long-term field work, however, has revealed the existence of stable, socially polyandrous groups in at least two populations, raising questions about the mechanism that allows two adult males to co-reside in the same group. I collected 21 months of behavioral data on 7 two-male groups of wild siamangs (Symphalangus syndactylus) in southern Sumatra (Indonesia) to test the hypothesis that dominance relationships regulate the interactions of adult male siamangs and ultimately facilitate multi-male social groups. A dominant male could clearly be identified in each dyad, based on a consistent direction of agonistic interactions, displacements and the maintenance of an advantageous position in the canopy. Males identified as dominant enjoyed greater social access to the resident female and monopolized copulations. These results suggest that gibbons possess the psycho-social flexibility to regulate intra-sexual aggression and live in multi-male social units under certain social conditions. I discuss the effects that relatedness between males and female choice have in determining this grouping pattern, and the role of male intolerance in the maintenance of primate mating systems. © 2015 Wiley Periodicals, Inc.

This study examined prospective relationships of green space attributes with adults initiating or maintaining recreational walking. Postal surveys were completed by 1036 adults living in Adelaide, Australia, at baseline (two time points in 2003-04) and follow-up (2007-08). Initiating or maintaining recreational walking was determined using self-reported walking frequency. Green space attributes examined were perceived presence, quality, proximity, and the objectively measured area (total and largest) and number of green spaces within a 1.6 km buffer drawn from the center of each study neighborhood. Multilevel regression analyses examined the odds of initiating or maintaining walking separately for each green space attribute. At baseline, participants were categorized into non-regular (n = 395), regular (n = 286), and irregular walkers (n = 313). Among non-regular walkers, 30% had initiated walking, while 70% of regular walkers had maintained walking at follow-up. No green space attributes were associated with initiating walking. However, positive perceptions of the presence of and proximity to green spaces and the total and largest areas of green space were significantly associated with a higher likelihood of walking maintenance over four years. Neighborhood green spaces may not assist adults to initiate walking, but their presence and proximity may facilitate them to maintain recreational walking over time. Copyright © 2013 Elsevier Inc.

Full Text Available Background: The number of children with down syndrome in Surabaya has reached 924 children. Prevalence of gingivitis and dental caries (91% and 93.8%, respectively occurs in children with down syndrome aged 6 to 20 years. Oral and dental health problems are found in children with down syndrome because they have physical and motoric limitation in maintaining oral and dental hygiene, thus require parental care from mother. Perceived parenting style includes responsiveness and demandingness. Perceived parenting is crucial for mother whose children have Down syndrome in order to guide their health behavior, particularly to maintain oral and dental health. Purpose: The study aimed to analyze correlation between perceived parenting style and mother’s behavior in maintaining dental health of children with Down syndrome. Method: This cross sectional analytical study involved 40 mothers of children aged 7-13 years with Down syndrome enrolled in Special Education Elementary Schools Surabaya and Association of Parents of Children with Down syndrome Surabaya. Data of perceived parenting style (responsiveness and demandingness and mother’s behavior in maintaining dental health were obtained by questionnaire. Composition of each item in questionnaire of perceived parenting style and mother’s behavior in maintaining dental health of children with Down syndrome was passed through validity and reliability test. Data analysis was carried out using multiple linear regression correlation test. Result: This present study showed that perceived parenting style is significantly correlated with mother’s behavior in maintaining dental health of children with Down syndrome (R = 0.630, p = 0.000, with perceived parental responsiveness as a strong predictor. Mean score and standard deviation of perceived parental responsiveness and demandingness were 33.00±2.99 and 15.55±1.99, respectively. Conclusion: Perceived maternal parenting style in children with Down

Maintaining Web Cache Coherency

Directory of Open Access Journals (Sweden)

2000-01-01

Full Text Available Document coherency is a challenging problem for Web caching. Once the documents are cached throughout the Internet, it is often difficult to keep them coherent with the origin document without generating a new traffic that could increase the traffic on the international backbone and overload the popular servers. Several solutions have been proposed to solve this problem, among them two categories have been widely discussed: the strong document coherency and the weak document coherency. The cost and the efficiency of the two categories are still a controversial issue, while in some studies the strong coherency is far too expensive to be used in the Web context, in other studies it could be maintained at a low cost. The accuracy of these analysis is depending very much on how the document updating process is approximated. In this study, we compare some of the coherence methods proposed for Web caching. Among other points, we study the side effects of these methods on the Internet traffic. The ultimate goal is to study the cache behavior under several conditions, which will cover some of the factors that play an important role in the Web cache performance evaluation and quantify their impact on the simulation accuracy. The results presented in this study show indeed some differences in the outcome of the simulation of a Web cache depending on the workload being used, and the probability distribution used to approximate updates on the cached documents. Each experiment shows two case studies that outline the impact of the considered parameter on the performance of the cache.

Cancer support groups are an important source of support for cancer patients, yet little is known about the challenges and training needs of both professionally trained and untrained leaders. The aim of this study was to discover the difficulties experienced and training desired by cancer support group leaders. Twenty-seven leaders of 34 cancer support groups participated in focus groups or individual interviews. Groups were purposively selected as representative of 173 support groups identified in New South Wales which were for adults with cancer and/or their adult carers and were not therapeutic or education-only groups. Difficulties identified included dealing with people's different communication styles and needs; dealing with recurrence, metastases and death; practical issues, including resources, setting the programme and funding security; maintaining personal balance and preventing burn out; establishing group credibility; dealing with group cycles; and leading groups in rural areas. Leaders also identified benefits and rewards from group leadership such as contributing to others' well-being, self-development and insight into others' lives. Non-professionally trained leaders experienced more difficulties, particularly in dealing with group process and practical issues. Difficulties identified were related both to working with a cancer population specifically and to working with groups in general. While some issues were common to both health professionals and non-health professionals, non-health professionals reported greater supportive needs. Clear guidelines, targeted training and development of better methods of support to reduce the stress and burn out experienced by group leaders are needed.

Do supervised weekly exercise programs maintain functional exercise capacity and quality of life, twelve months after pulmonary rehabilitation in COPD?

Directory of Open Access Journals (Sweden)

Alison Jennifer A

2007-05-01

Full Text Available Abstract Background Pulmonary rehabilitation programs have been shown to increase functional exercise capacity and quality of life in COPD patients. However, following the completion of pulmonary rehabilitation the benefits begin to decline unless the program is of longer duration or ongoing maintenance exercise is followed. Therefore, the aim of this study is to determine if supervised, weekly, hospital-based exercise compared to home exercise will maintain the benefits gained from an eight-week pulmonary rehabilitation program in COPD subjects to twelve months. Methods Following completion of an eight-week pulmonary rehabilitation program, COPD subjects will be recruited and randomised (using concealed allocation in numbered envelopes into either the maintenance exercise group (supervised, weekly, hospital-based exercise or the control group (unsupervised home exercise and followed for twelve months. Measurements will be taken at baseline (post an eight-week pulmonary rehabilitation program, three, six and twelve months. The exercise measurements will include two six-minute walk tests, two incremental shuttle walk tests, and two endurance shuttle walk tests. Oxygen saturation, heart rate and dyspnoea will be monitored during all these tests. Quality of life will be measured using the St George's Respiratory Questionnaire and the Hospital Anxiety and Depression Scale. Participants will be excluded if they require supplemental oxygen or have neurological or musculoskeletal co-morbidities that will prevent them from exercising independently. Discussion Pulmonary rehabilitation plays an important part in the management of COPD and the results from this study will help determine if supervised, weekly, hospital-based exercise can successfully maintain functional exercise capacity and quality of life following an eight-week pulmonary rehabilitation program in COPD subjects in Australia.

Maintaining the Feasibility of Hard Real–Time Systems with a Reduced Number of Priority Levels

Directory of Open Access Journals (Sweden)

Qureshi Muhammad Bilal

2015-12-01

Full Text Available When there is a mismatch between the cardinality of a periodic task set and the priority levels supported by the underlying hardware systems, multiple tasks are grouped into one class so as to maintain a specific level of confidence in their accuracy. However, such a transformation is achieved at the expense of the loss of schedulability of the original task set. We further investigate the aforementioned problem and report the following contributions: (i a novel technique for mapping unlimited priority tasks into a reduced number of classes that do not violate the schedulability of the original task set and (ii an efficient feasibility test that eliminates insufficient points during the feasibility analysis. The theoretical correctness of both contributions is checked through formal verifications. Moreover, the experimental results reveal the superiority of our work over the existing feasibility tests by reducing the number of scheduling points that are needed otherwise.

How to keep punishment to maintain cooperation: Introducing social vaccine

Science.gov (United States)

Yamamoto, Hitoshi; Okada, Isamu

2016-02-01

Although there is much support for the punishment system as a sophisticated approach to resolving social dilemmas, more than a few researchers have also pointed out the limitations of such an approach. Second-order free riding is a serious issue facing the punishment system. Various pioneering works have suggested that an anti-social behavior or noise stemming from a mutation may, surprisingly, be helpful for avoiding second-order freeloaders. In this work, we show through mathematical analysis and an agent-based simulation of a model extending the meta-norms game that the coercive introduction of a small number of non-cooperators can maintain a cooperative regime robustly. This paradoxical idea was inspired by the effect of a vaccine, which is a weakened pathogen injected into a human body to create antibodies and ward off infection by that pathogen. Our expectation is that the coercive introduction of a few defectors, i.e., a social vaccine, will help maintain a highly cooperative regime because it will ensure that the punishment system works.

Maintaining Sibling Relationships for Children in Foster and Adoptive Placements.

James, Sigrid; Monn, Amy R; Palinkas, Lawrence A; Leslie, Laurel K

2008-01-01

To better understand the nature of sibling relationships among children in foster or adoptive placement and the challenges and processes involved in maintaining these relationships, we conducted an exploratory analysis of data collected from semi-structured interviews with caregivers of 14 foster and adopted children in San Diego County. We identified three patterns of placement histories and living situations which appeared to impact the degree of contact maintained with siblings: (1) children who had never lived together and were not currently placed together; (2) children who at some point lived with or were placed together with their siblings, but were now separated from them; and (3) children who had lived with their siblings all their life and were placed together with at least some of their siblings at the time of the interview. Children's current living situations and placement histories, caregivers' experiences and perceptions of feasibility and desirability of sibling contact, and the sibling relationship itself are primary determinants in the development and maintenance of contact between siblings. Implications for child welfare policy and practice are discussed.

Human-factors methods for assessing and enhancing power-plant maintainability

International Nuclear Information System (INIS)

Seminara, J.L.

1982-05-01

EPRI Final Report NP-1567, dated February 1981, presented the results of a human factors review of plant maintainability at nine power plants (five nuclear and four fossil). This investigation revealed a wide range of plant and equipment design features that can potentially compromise the effectiveness, safety, and productivity of maintenance personnel. The present study is an extension of the earlier work. It provides those utilities that did not participate in the original study with the methodological tools to conduct a review of maintenance provisions, facilities, and practices. This report describes and provides a self-review checklist; a structured interview; a task analysis approach; methods for reviewing maintenance errors or accidents; and recommended survey techniques for evaluating such factors as noise, illumination, and communications. Application of the human factors methods described in this report should reveal avenues for enhancing existing power plants from the maintainability and availability standpoints. This document may also serve a useful purpose for designers or reviewers of new plant designs or near-operational plants presently being constructed

Treatment issues in the group psychotherapy of addicted physicians.

Science.gov (United States)

Fayne, M; Silvan, M

1999-01-01

For the most part, physician-addict patients are affable, cooperative and tend to be bright, verbal and engaging. However, on a deeper level they experience significant internal obstacles to truly using treatment. The role of the healer adopted after years of training and work experience is not easily exchanged for the role of patient. Furthermore, the armour of defenses and character style that have been built up over a lifetime is resistant to modification. Additionally, most of these patients have not chosen to change. They have been ordered into treatment under considerable duress and are aware that retaining their hard-earned careers is dependent on their successful performance in treatment. Given all these difficulties it is striking that the vast majority of these patients gradually come to experience a genuine and meaningful connection to the group and the therapeutic process. They develop close relationships with their fellow group members and come to use them as a support system, even at times when the group is not in session. They report looking forward to group and missing it when it does not meet. In this context they begin to take risks by sharing on a deeper level and slowly bring to the group issues in their life other than addiction. Their devotion to group is reflected by the fact that when no longer mandated, many continue voluntarily and maintain that the experience is central to their recovery. One of the major reasons recovering physicians are able to make this connection is that behind their fear of interpersonal relationships is a tremendous wish to join with others. Many report profound relief at discovering they are not alone and are able to use group to address their deeply felt sense of shame. For many this is their first experience of such strong feelings of attachment and affiliation to a group of peers. Their prior professional experience did not routinely allow for such relationships and as Smith (1978) has observed, their experience

Full Text Available Long-term outdoor localization remains challenging due to the high energy profiles of GPS modules. Duty cycling the GPS module combined with inertial sensors can improve energy consumption. However, inertial sensors that are kept active all the time can also drain mobile node batteries. This paper proposes duty cycling strategies for inertial sensors to maintain a target position accuracy and node lifetime. We present a method for duty cycling motion sensors according to features of movement events, and evaluate its energy and accuracy profile for an empirical data trace of cattle movement. We further introduce the concept of group-based duty cycling, where nodes that cluster together can share the burden of motion detection to reduce their duty cycles. Our evaluation shows that both variants of motion sensor duty cycling yield up to 78% improvement in overall node power consumption, and that the group-based method yields an additional 20% power reduction during periods of low mobility.

Pancreatic islet transplantation has been recognized as an effective treatment for Type 1 diabetes; however, there is still plenty of room to improve transplantation efficiency. Because islets are metabolically active they require high oxygen to survive; thus hypoxia after transplant is one of the major causes of graft failure. Knowing the optimal oxygen tension for isolated islets would allow a transplant team to provide the best oxygen environment during pre- and post-transplant periods. To address this issue and begin to establish empirically determined guidelines for islet maintenance, we exposed in vitro cultured islets to different partial oxygen pressures (pO2) and assessed changes in islet volume, viability, metabolism, and function. Human islets were cultured for 7 days in different pO2 media corresponding to hypoxia (90 mmHg), normoxia (160 mmHg), and hyerpoxia (270 or 350 mmHg). Compared to normoxia and hypoxia, hyperoxia alleviated the loss of islet volume, maintaining higher islet viability and metabolism as measured by oxygen consumption and glucose-stimulated insulin secretion responses. We predict that maintaining pre- and post-transplanted islets in a hyperoxic environment will alleviate islet volume loss and maintain islet quality thereby improving transplant outcomes.

Full Text Available Ageing is associated with a decline in daily functioning and mobility. A physically active life and physical exercise can minimize the decline of daily functioning and improve the physical-, psychological- and social functioning of older adults. Despite several advantages of group-based exercise programs, older adults participating in such interventions often do not meet the frequency, intensity or duration of exercises needed to gain health benefits. An exercise program that combines the advantages of group-based exercises led by an instructor with tailored home-based exercises can increase the effectiveness. Technology can assist in delivering a personalized program. The aim of the study was to determine the susceptibility of older adults currently participating in a nationwide group-based exercise program to such a blended exercise program. Eight focus-groups were held with adults of 55 years of age or older. Two researchers coded independently the remarks of the 30 participants that were included in the analysis according to the three key concepts of the Self Determination Theory: autonomy, competence and relatedness. The results show that maintaining self-reliance and keeping in touch with others were the main motives to participate in the weekly group-based exercises. Participants recognized benefits of doing additional home-based exercises, but had concerns regarding guidance, safety and motivation. Furthermore, some participants strongly rejected the idea to use technology to support them in doing exercises at home, but the majority was open to it. Insights are discussed how these findings can help design novel interventions that can increase the wellbeing of older adults and preserve an independent living.

(1) Seawater-adapted Mallard ducks maintained in the laboratory will freely consume food that has been contaminated with either any one of a variety of crude oils or a petroleum derivative such as No. 2 fuel oil. (2) During a 100-day experimental period total masses of petroleum equivalent to 50% of the mean body weight were consumed by some birds and many showed no apparent symptoms of distress. (3) The consumption of petroleum-contaminated food was frequently accompanied by a persistent hyperphagia but no clear patterns of change in body weight were associated with this condition. (4) Among those birds that survived the 100-day experimental period only small changes in mean body weight were observed between successive weighings and in most instances these represented less than 10% of the previously recorded weight. (5) In all groups, including those maintained on uncontaminated food, most of the mortality occurred following exposure to continuous mild cold stress. The total number of deaths in the groups given petroleum-contaminated food, however, was always higher than that among birds given uncontaminated food. (6) The spate of mortality that occurred in groups given petroleum-contaminated food usually occurred earlier, lasted longer, and involved more birds than it did among groups fed uncontaminated food. (7) The pattern of each episode of mortality was sometimes quantitatively related to the concentration of petroleum in the food and a striking range of relative toxicities were observed among the crude oils from different geographic regions. (8) Throughout the experiment, the mean body weight of the birds that died was always significantly less than that of the survivors in the same group; in all instances most of the loss in weight occurred during the 2 weeks preceding death. (9) Autopsy revealed that adrenal hypertrophy and lymphoepithelial involution were characteristic in all of the birds that died, suggesting that a high level of adrenocortical

Studies investigating the relation between risk profiles and cardiovascular disease have measured risk at baseline only. We investigated maintenance and changes of risk profiles over time and their potential impact on incident cardiovascular disease. Population-based cohort study. Risk factors were measured at baseline (1987-1991) among 5574 cardiovascular disease-free adults aged 20-59 years. They were classified into four risk categories according to smoking status, presence of diabetes and widely accepted cut-off values for blood pressure, total cholesterol/HDL-ratio and body mass index. Categories were subdivided (maintenance, deterioration, improvement) based on risk factor levels at six and 11 years of follow-up. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for cardiovascular disease incidence 5-10 years following the risk-change period were fitted using Cox proportional hazards models. Only 12% of participants were low risk at baseline, and only 7% maintained it. Participants who maintained a low risk profile over 11 years had seven times lower risk of cardiovascular disease (HR: 0.14, 95% CI: 0.05-0.41) than participants with long-term high risk profile, whereas those low risk at baseline whose profile deteriorated had three times lower risk (HR: 0.36, 95% CI: 0.18-0.71). Our results suggest that, within each baseline risk profile group, compared with a stable profile, improving profiles may be associated with up to two-fold lower HRs, and deteriorating profiles with about two-fold higher HRs. Our study, using long-term risk profiles, demonstrates the full benefits of low risk profile. These findings underscore the importance of achieving and maintaining low risk from young adulthood onwards. © The European Society of Cardiology 2014.

Communication is a fundamental element of care at every level of nursing practice. It is important, therefore, for nurse managers to create environments that promote and encourage good communication, and help nurses to develop their communication skills formally and informally. This article discusses the effects of communication on the quality of care. It examines nurses' professional duty to maintain good communication skills and how managers can help them do this. It also discusses nurse managers' communication skills in the context of leadership style, conflict resolution and self-awareness. Finally, it considers the notion of shared governance as good practice.

The distribution of ultra-narrow linewidth laser radiation is an integral part of many challenging metrological applications. Changes in the optical pathlength induced by environmental disturbances compromise the stability and accuracy of optical fibre networks distributing the laser light and call for active phase noise cancellation. Here we present a laboratory scale optical (at 578 nm) fibre network featuring all polarisation maintaining fibres in a setup with low optical powers available and tracking voltage-controlled oscillators implemented. The stability and accuracy of this system reach performance levels below 1 × 10-19 after 10 000 s of averaging.

We have previously found improved cognitive function 6 weeks after ECT in this group. The aim of this study was to report 6-month follow-up results from the same prospective project monitoring cognitive effects of ECT. Thirty-one patients with major depressive disorder were assessed with the MATRICS Consensus Cognitive Battery (MCCB, the Everyday Memory Questionnaire (EMQ, and the Montgomery-Åsberg Depression Rating Scale (MADRS prior to, 6 weeks, and 6 months after ECT.Compared to baseline, the Speed of Processing, Attention/Vigilance, and Reasoning/Problem Solving test results were significantly improved. The depression score was significantly reduced. There were no changes in subjective memory complaint. There were no significant relationship between the EMQ and the MCCB subtests, but a significant correlation between current depression level and the EMQ.Six months after ECT the cognitive improvement reported at 6 weeks follow-up was maintained and extended. The corresponding decrease in depressive symptoms and stability in subjectively reported memory complaints suggests that the antidepressant effects of ECT do not occur at the expense of cognitive function.

Through a commitment to high performance, school districts are discovering that smart energy choices can create lasting benefits for students, communities, and the environment. For example, an energy efficient school district with 4,000 students can save as much as $160,000 a year in energy costs. Over 10 years, those savings can reach $1.6 million, translating into the ability to hire more teachers, purchase more textbooks and computers, or invest in additional high performance facilities. Beyond these bottomline benefits, schools can better foster student health, decrease absenteeism, and serve as centers of community life. The U.S. Department of Energy's EnergySmart Schools Program promotes a 30 percent improvement in existing school energy use. It also encourages the building of new schools that exceed code (ASHRAE 90.11999) by 50 percent or more. The program provides resources like this Guide to Operating and Maintaining EnergySmart Schools to assist school decisionmakers in planning, financing, operating, and maintaining energy efficient, high performance schools. It also offers education and training for building industry professionals. Operations and maintenance refer to all scheduled and unscheduled actions for preventing equipment failure or decline with the goal of increasing efficiency, reliability, and safety. A preventative maintenance program is the organized and planned performance of maintenance activities in order to prevent system or production problems or failures from occurring. In contrast, deferred maintenance or reactive maintenance (also called diagnostic or corrective maintenance) is conducted to address an existing problem. This guide is a primary resource for developing and implementing a districtor schoolwide operations and maintenance (O&M) program that focuses on energy efficiency. The EnergySmart Schools Solutions companion CD contains additional supporting information for design, renovation, and retrofit projects. The objective

The use of ultrasound to diagnose appendicitis in children is well-documented but not universally employed outside of pediatric academic centers, especially in the United States. Various obstacles make it difficult for institutions and radiologists to abandon a successful and accurate CT-based imaging protocol in favor of a US-based protocol. To describe how we overcame barriers to implementing a US-based appendicitis protocol among a large group of nonacademic private-practice pediatric radiologists while maintaining diagnostic accuracy and decreasing medical costs. A multidisciplinary team of physicians (pediatric surgery, pediatric emergency medicine and pediatric radiology) approved an imaging protocol using US as the primary modality to evaluate suspected appendicitis with CT for equivocal cases. The protocol addressed potential bias against US and accommodated for institutional limitations of radiologist and sonographer experience and availability. Radiologists coded US reports according to the probability of appendicitis. Radiology reports were compared with clinical outcomes to assess diagnostic accuracy. During the study period, physicians from each group were apprised of the interim US protocol accuracy results. Problematic cases were discussed openly. A total of 512 children were enrolled and underwent US for evaluation of appendicitis over a 30-month period. Diagnostic accuracy was comparable to published results for combined US/CT protocols. Comparing the first 12 months to the last 12 months of the study period, the proportion of children achieving an unequivocal US result increased from 30% (51/169) to 53% (149/282) and the proportion of children undergoing surgery based solely on US findings increased from 55% (23/42) to 84% (92/109). Overall, 63% (325/512) of patients in the protocol did not require a CT. Total patient costs were reduced by $30,182 annually. We overcame several barriers to implementing a US protocol.

The purpose of this study was to clarify the characteristics of female elderly participants of a group exercise organized by the participants themselves and the changes in their physical, mental, and social health, and life function. Findings of this study will be used for promoting effective preventive care. The subjects whose characteristics were analyzed were 394 participants and 757 nonparticipants of the group exercise. Those whose changes in health were analyzed were 52 participants and 114 nonparticipants. Locomotion Check and self-rated health score were used as indices of physical health. World Health Organization-Five well-being (S-WHO-5-J) index and self-rated life satisfaction level were used as indices of mental health. Satisfaction level of social activities was one of indices of social health. The Tokyo Metropolitan Institute of Gerontology Index of Competence was used as an index of life function. The health-examination data analyzed were Body Mass Index, waist circumference, blood pressure, lipid profiles, and HbA1c level. In the participant group, the proportions of those who lived alone, who were affluent, and who had no job were higher than those in the nonparticipant group. The indices of physical, mental and social health and life function were higher in the participant group. There was no significant difference in the 5-year trend of health-examination data between the two groups. There was no significant difference in the yearly change in the indices of physical health and life function. The S-WHO-5-J index, self-rated life satisfaction level, and satisfaction level of social activities were maintained or improved in the participant group. The results suggest the possible usefulness of the group exercise for maintaining the mental and social health of elderly women.

Stem cell niche-specific Ebf3 maintains the bone marrow cavity.

Bone marrow is the tissue filling the space between bone surfaces. Hematopoietic stem cells (HSCs) are maintained by special microenvironments known as niches within bone marrow cavities. Mesenchymal cells, termed CXC chemokine ligand 12 (CXCL12)-abundant reticular (CAR) cells or leptin receptor-positive (LepR + ) cells, are a major cellular component of HSC niches that gives rise to osteoblasts in bone marrow. However, it remains unclear how osteogenesis is prevented in most CAR/LepR + cells to maintain HSC niches and marrow cavities. Here, using lineage tracing, we found that the transcription factor early B-cell factor 3 (Ebf3) is preferentially expressed in CAR/LepR + cells and that Ebf3-expressing cells are self-renewing mesenchymal stem cells in adult marrow. When Ebf3 is deleted in CAR/LepR + cells, HSC niche function is severely impaired, and bone marrow is osteosclerotic with increased bone in aged mice. In mice lacking Ebf1 and Ebf3 , CAR/LepR + cells exhibiting a normal morphology are abundantly present, but their niche function is markedly impaired with depleted HSCs in infant marrow. Subsequently, the mutants become progressively more osteosclerotic, leading to the complete occlusion of marrow cavities in early adulthood. CAR/LepR + cells differentiate into bone-producing cells with reduced HSC niche factor expression in the absence of Ebf1/Ebf3 Thus, HSC cellular niches express Ebf3 that is required to create HSC niches, to inhibit their osteoblast differentiation, and to maintain spaces for HSCs. © 2018 Seike et al.; Published by Cold Spring Harbor Laboratory Press.

Process equipment for pyroprocessing are being developed at KAERI (Korea Atomic Energy Research Institute). Those equipment should be operated and maintained in a fully remote manner in the argon gas filled cell of PRIDE (PyRoprocess Integrated inactive DEmonstration facility) at KAERI because direct human access to the in-cell is not possible during an operation due to the high toxicity of the argon gas. To make such process equipment remotely operable and maintainable, their design developments have been tested and evaluated in a simulator before they are constructed. A simulator as a means of evaluating the remote operability and maintainability of the design models of process equipment for pyroprocessing is described, and results of the design models tested and evaluated in a simulator are presented

Respecting and protecting the confidentiality of data and the privacy of individuals regarding the information that they have given as participants in a research project is a cornerstone of complying with accepted research standards. However, in longitudinal studies, establishing and maintaining privacy is often challenging because of the necessity of repeated contact with participants. A novel internet-based solution is introduced here, which maintains privacy while at the same time ensures linkage of data to individual participants in a repeated measures design. With the use of the anonymous repeated measurements via email (ARME) procedure, two separate one-way communication systems are established through ad hoc email accounts and a secure study website. Strengths and limitations of the approach are discussed.

To pilot a second support group intervention study promoting self-transcendence perspectives and activities and to document changes over time in well-being in support group participants compared with nonparticipants. Quasiexperimental, partial randomization, preference trial design. An urban breast cancer resource center established by survivors. 41 women with newly diagnosed breast cancer were recruited, and 39 completed the study. 22 women participated in three intervention support groups; 17 were in a comparison group. The intervention was an eight-week, closed support group based on self-transcendence theory. Data were collected three times during 14 months. Support group intervention, self-transcendence, and emotional and physical well-being. The intervention group had lower scores than the comparison group on self-transcendence and well-being variables at baseline (time [T] 1). Scores were higher for both groups postintervention (T2), with no differences between groups. One year postintervention (T3), intervention group scores again were lower than comparison group scores. Intervention group T3 scores were unchanged from T2. Most potential participants were unwilling to risk being randomized into a nonpreferred group. Activities based on self-transcendence theory were associated with expanded perspectives and activities and an improved sense of well-being in support group participants at the end of the intervention, but not one year later. Findings from the pilot studies informed a study currently in progress. Nurses should maintain awareness of local resources for support and make that information available to women when they are newly diagnosed with breast cancer, during their treatment, and later.

We formed a self-funded hypertension treatment group in a resource-poor community in rural Honduras. After training community health workers and creating protocols for standardized treatment, we used group membership fees to maintain the group, purchase generic medications in bulk on the local market, and hire a physician to manage treatment. We then assessed whether participation in the group improved treatment, medication adherence, and hypertension control. This is a program evaluation using quasi-experimental design and no control group. Using data from the 86 members of the hypertension treatment group, we analyzed baseline and follow-up surveys of members, along with 30 months of clinical records of treatment, medication adherence, and blood pressure readings. Our initial hypertension needs assessment revealed that at baseline, community hypertensives relied on the local Ministry of Health clinic as their source of anti-hypertensive medications and reported that irregular supply interfered with medication adherence. At baseline, hypertension group members were mainly female, overweight or obese, physically active, non-smoking, and non-drinking. After 30 months of managing the treatment group, we found a significant increase in medication adherence, from 54.8 to 76.2% (p<0.01), and hypertension control (<140/90 mmHg), from 31.4 to 54.7% (p<0.01). We also found a mean monthly decrease of 0.39 mmHg in systolic blood pressure (p<0.01). At the end of the 30-month observation period, the local Ministry of Health system had increased provision of low-cost anti-hypertensive medications and adopted the hypertension treatment group's treatment protocols. Formation of a self-funded, community-based hypertension treatment group in a rural, resource-poor community is feasible, and group participation may improve treatment, medication adherence, and hypertension control and can serve as a political driver for improving hypertension treatment services provided by the public

Human factors engineering is an interdisciplinary science and technology concerned with shaping the design of machines, facilities, and operational environments to promote safe, efficient, and reliable performance on the part of operators and maintainers of equipment systems. The human factors aspects of five nuclear power plants and four fossil fuel plants were evaluated using such methods as a checklist guided observation system, structured interviews with maintenance personnel, direct observations of maintenance tasks, reviews of procedures, and analyses of maintenance errors or accidents by means of the critical incident technique. The study revealed a wide variety of human factors problem areas, most of which are extensively photodocumented. The study recommends that a more systematic and formal approach be adopted to ensure that future power plants are human engineered to the needs of maintenance personnel

Individual prenatal care is intended to prevent poor perinatal outcomes and provide education to women throughout pregnancy, childbirth, and the postpartum period through a series of one-on-one encounters between a woman and her obstetrician or other obstetric care provider. Concerns regarding increasing health care costs, health care provider availability, dissatisfaction with wait times, and the minimal opportunity for education and support associated with the individual care model have given rise to interest in alternative models of prenatal care. One alternative model, group prenatal care, may be beneficial or preferred for some practice settings and patient populations, although individual prenatal care remains standard practice. Group prenatal care models are designed to improve patient education and include opportunities for social support while maintaining the risk screening and physical assessment of individual prenatal care. Bringing patients with similar needs together for health care encounters increases the time available for the educational component of the encounter, improves efficiency, and reduces repetition. Evidence suggests patients have better prenatal knowledge, feel more ready for labor and delivery, are more satisfied with care in prenatal care groups, and initiate breastfeeding more often. There is no evidence that suggests that group prenatal care causes harm. Individual and group care models warrant additional study with a goal of demonstrating differences in outcomes and identifying populations that benefit most from specific care models.

Lidbeck, J

2003-06-01

The objective of this study was to evaluate the maintenance of treatment goals of a short cognitive-behavioural group treatment programme for the management of somatization disorders in primary care. In a previous controlled 6-month follow-up study, patients with somatization disorders (n=32) improved with respect to illness and somatic preoccupation, hypochondriasis, and medication usage. In the present report the same group of patients were also investigated one-and-a-half year after initial treatment. The long-term follow-up manifested maintained improvement with respect to hypochondriasis. There was additional reduction of anxiety and psychosocial preoccupation, whereas somatization and depression-anxiety scores improved progressively. A short cognitive-behavioural group treatment of psychosomatic patients can be useful in primary care and may manifest maintained or progressive beneficial outcome.

In this paper, we proposed a novel object-based dense matching method specially for the high-precision disparity map of building objects in urban areas, which can maintain accurate object structure characteristics. The proposed framework mainly includes three stages. Firstly, an improved edge line extraction method is proposed for the edge segments to fit closely to building outlines. Secondly, a fusion method is proposed for the outlines under the constraint of straight lines, which can maintain the building structural attribute with parallel or vertical edges, which is very useful for the dense matching method. Finally, we proposed an edge constraint and outline compensation (ECAOC) dense matching method to maintain building object structural characteristics in the disparity map. In the proposed method, the improved edge lines are used to optimize matching search scope and matching template window, and the high-precision building outlines are used to compensate the shape feature of building objects. Our method can greatly increase the matching accuracy of building objects in urban areas, especially at building edges. For the outline extraction experiments, our fusion method verifies the superiority and robustness on panchromatic images of different satellites and different resolutions. For the dense matching experiments, our ECOAC method shows great advantages for matching accuracy of building objects in urban areas compared with three other methods.

Resistances in the first session of psychodrama psychotherapy group with adults.

Science.gov (United States)

Drakulić, Aleksandra Mindoljević

2010-06-01

Resistance refers to all types of behaviour that oppose the exploration processes in the therapeutic process and inhibit work. Very common types of resistances, such as forgetting the time of session, being late, non-payment of sessions and such are found in every type of psychotherapy, including psychodrama psychotherapy. The attempt to break resistance in order to evoke changes could be dangerous as it represents the necessary defence mechanism and it is also a vital element of the person's functioning in therapy. In psychodrama, which is a type of action method of group psychotherapy, resistance can manifest through continuous verbalization of problems, in not wanting to act out the problem, the protagonist's typical non-verbal message or the most obvious manifestation: the absence of the protagonist. This paper will be on the typical resistance which the therapist has noticed during the first session of psychodrama psychotherapy, with a small group of adult clients. As the group was young and with undeveloped cohesiveness, resistance represented a certain balancing power for maintaining mental homeostasis of the group.

Effects of Haloperidol on Responding Maintained with Food and Sucrose-Water

Full Text Available The “hedonic” value of reinforcers is mediated by dopamine. Accordingly,haloperidol diminishes the value of reinforcers, by interfering with the emission of operant behaviors. Alternatively, the interference of dopamine transmission does not prevent animals from eating food. Thus, reinforcers remain intact after the administration of haloperidol. We assessed these possibilities with eight Wistar rats and two types of reinforcers, food-pellets and sucrose-water, delivered under multiple reinforcement schedules. Ingeneral, lever presses maintained by food-pellets were higher than those maintained by sucrose-water. Haloperidol produced dose-related decreases in lever presses and obtained reinforcers. Different doses had no effect on the number of lever presses. Subcutaneous administrations of haloperidol produced higher decreases in lever presses than intra-peritoneal administrations. Decreases in lever pressing were not necessarily accompanied by substantial reductions in obtained food-pellets and sucrose-water reinforcers; underthe effects of haloperidol rats continued to produce a considerable number of both types of reinforcers.

To test group-based Female-Specific Cognitive Behavioral Therapy (G-FS-CBT) for women with Alcohol Use Disorder (AUD) against an individual Female-Specific Cognitive Behavioral Therapy (I-FS-CBT). This aims of this paper are to describe G-FS-CBT development, content, feasibility, acceptability, group process, engagement in treatment, and within- and post-treatment outcomes. Women with AUD (n=155) were randomly assigned to 12 manual-guided sessions of G-FS-CBT or I-FS-CBT; 138 women attended at least one treatment session. Women in G-FS-CBT attended fewer sessions (M=7.6) than women in I-FS-CBT (M=9.7; p<.001). Women in both conditions reported high satisfaction with the treatments. Independent coders rated high fidelity of delivery of both G-FS-CBT and I-FS-CBT. Therapeutic alliance with the therapist was high in both conditions, with I-FS-CBT being slightly but significantly higher than G-FS-CBT. In the first six weeks of treatment, women in both treatment conditions significantly reduced their percent drinking days (PDD) and percent heavy days drinking (PHD) by equivalent amounts, maintained through the rest of treatment and the 12month follow up with no treatment condition effects. Women reported significant improvement in all but one of the secondary outcomes during treatment; gains made during treatment in depression, anxiety, autonomy, and interpersonal problems were maintained during the follow-up period, while gains made during treatment in use of coping skills, self-efficacy for abstinence, self-care, and sociotropy deteriorated over follow up but remained improved compared to baseline. Findings support the feasibility, acceptability, and efficacy of a group format for female-specific CBT for AUD, a new 12-session, single gender, community friendly, group therapy with programming specifically for women. Similar, positive outcomes for individual and group treatment formats were found for drinking, mood, coping skills, self-confidence, interpersonal

Booster sessions as a means of maintaining the benefits of psycho-educational programs have received little attention in caregiving research. Caregivers were offered a booster session following participation in a program entitled Learning to Become a Family Caregiver (LBFC) intended to facilitate transition to the caregiver role after diagnostic disclosure of dementia in a relative. The 90-minute booster session served to review program content and afforded the opportunity to discuss and practice learned skills. This study sought to test the efficacy of the booster session in maintaining or recovering program effects at six months post-program. Participants in the program were randomly assigned to a group that received the booster session (n = 31) or a group that did not (n = 29). A third control group was also formed, which continued to receive only the usual care provided in memory clinics. Eligible participants - French-speaking primary caregivers of a relative diagnosed with Alzheimer's in the past nine months - were recruited in memory clinics in Quebec (Canada). Participants were blindly assessed before randomization and six months after the booster session on outcomes associated with a healthy role transition. Prediction analyses revealed one significant positive effect of the booster session: emergence of preparedness to provide care. Moreover, with or without the booster session, the program continued to have a positive effect on psychological distress and contributed to the emergence of self-efficacy in dealing with caregiving situations. The booster session had no significant effect on knowledge of services, planning for future care needs, use of reframing as a coping strategy, perceived informal support, and family conflicts. The limited effect observed is discussed in terms of the booster session's content and intensity. Recommendations are made for designing future research on the effect of booster sessions, including the importance of including a

Highlights: ► Building a new phenomenological theory model to investigate the relation about the irradiation induced loss with irradiation dose and dose rate. ► The Gamma ray irradiation induced loss of the “Capsule” type and “Panda” type polarization maintaining optical fibers at 1310 nm wavelength are investigated. ► The anti irradiation performance of the “Panda” type polarization maintaining optical fiber is better than that of the “Capsule” type polarization maintaining optical fiber, the reason is that the stress region doped by GeO 2 . - Abstract: The Gamma ray irradiation induced loss of the “Capsule” type and “Panda” type polarization maintaining optical fibers at 1310 nm wavelength are investigated. A phenomenological theory model is introduced and the influence of irradiation dose and dose rate on the irradiation induced loss is discussed. The phenomenological theoretical results are consistent with the experimental results of the irradiation induced loss for the two types of polarization maintaining optical fibers. The anti irradiation performance of the “Panda” type polarization maintaining optical fiber is better than that of the “Capsule” type polarization maintaining optical fiber, the reason is that the stress region dope with GeO 2 . Meanwhile, both of the polarization maintaining optical fiber irradiation induced loss increase with increasing the irradiation dose. In the case of same dose, the high dose rate Gamma ray irradiation induced optical fiber losses are higher than that of the low dose rate.

Full Text Available Despite allocating huge budgets to civil engineering projects, detailed planning, and employing human resources, project managers still face time, cost, and quality constraints. Most of these challenges are due to a lack of integration of different project phases and the limitations of the presence of construction and maintenance contractors in the initial stages of the project. Considering the benefits of applying constructability, operability, and maintainability (COM concepts, many problems caused by lack of coordination, or duplications and weakness in management, and also time and extra costs due to lack of presence of construction and maintenance contractors in the early stages of the project are resolvable. In this regard, various studies have investigated the benefits of applying these concepts; however, there has been no comprehensive analysis of the benefits of COM. As a result of focus on the benefits of implementation of these concepts and evaluating the effect of each of these strategies and benefits, from different perspectives during various time periods, managers can increase project efficiency and productivity, and improve their performance, through using concepts and strategies of their implementation. This research aims to evaluate the trend of studies on the benefits of implementing constructability, operability, and maintainability in the construction industry. For that, the in-depth literature review method is applied. For qualitative analysis of the obtained information, descriptive analysis has been used. Then, the data was coded, and classified using Excel Software for quantitative data analysis. Finally, the charts presented were evaluated according to the classified fields of study. The necessity of performing such a study is significant because of the fact that a large share of a project’s problems, such as lack of plans’ integration and weakness of administrative system, and increasing time and cost, are due to

To gain an understanding towards the perspectives of hospitalized inpatients in Indonesia regarding maintaining dignity during clinical care. Dignity is a basic human right that is crucial for an individual's well-being. Respect for a person as a valuable human is a concept that is comparable to treating a person with dignity. Maintaining patient's dignity is an ethical goal of nursing care. Nevertheless, the concept is highly dependent on cultural context. This issue has not been well studied in Indonesia. This study used a qualitative descriptive design. Thirty-five participants were recruited by purposive sampling from medical to surgical wards of six public hospitals in Eastern Java, Indonesia. Data were collected in 2016 through individual face-to-face semi-structured interviews. Inductive content analysis was applied to the data. Four major categories which described qualities of nursing care essential for maintaining a patient's dignity in clinical care settings were revealed: (1) responsiveness; (2) respectful nurse-patient relationships; (3) caring characteristics and (4) personalized service. Our findings provide a cultural viewpoint of dignity for care recipients in Indonesia. The findings provide empirical support for linking dignified care and person-centred care principles with regards to cultural sensitivity. Nurses must not only be clinically competent but also culturally competent. The ability to provide culturally competent care is important for nurses as a strategy to maintain patient dignity during hospitalized care. © 2017 John Wiley & Sons Ltd.

Building and maintaining media contacts

Fenton, Bob

2000-01-01

This presentation is answering the question: 'how does British Energy build and maintain its relationships with journalists in so many areas', not only the basic industrial correspondents that you would expect to have to deal with an industry British Energy, but those dealing with science and technology, the environment, personnel and training, city and financial, political, and on and on, and that is just the national press. Then add the local and regional media around power station sites - literally hundreds of contacts and you start to get an idea about the size of our media contact database. But it is managed it rather well. Every six months British Energy takes part in a survey run by one of the UK's leading market research companies who conducts a poll among journalists and then rate each company's performance. In the last three years British Energy has not been outside the top five in most categories, and in the top two in several. The answer is a lot of work over a long period of time. You cannot expect to build trusting relationships with a journalist overnight. At British Energy the key is being open and honest, and always available. Of course good media relations is not a one-way street, and there has to be some element of compromise if you are to achieve a relationship based on mutual trust

Stepping Stones Triple P (SSTP) is a parenting program designed for families of a child with a disability. The current study involved a randomized controlled trial of Group Stepping Stones Triple P (GSSTP) for a mixed-disability group. Participants were 52 families of children diagnosed with an Autism Spectrum Disorder, Down syndrome, Cerebral Palsy, or an intellectual disability. The results demonstrated significant improvements in parent-reported child behavior, parenting styles, parental satisfaction, and conflict about parenting. Results among participants were similar despite children's differing impairments. The intervention effect was maintained at 6-month follow-up. The results indicate that GSSTP is a promising intervention for a mixed-disability group. Limitations of the study, along with areas for future research, are also discussed. © FPI, Inc.

Reliability and Maintainability Engineering - A Major Driver for Safety and Affordability

The United States National Aeronautics and Space Administration (NASA) is in the midst of an effort to design and build a safe and affordable heavy lift vehicle to go to the moon and beyond. To achieve that, NASA is seeking more innovative and efficient approaches to reduce cost while maintaining an acceptable level of safety and mission success. One area that has the potential to contribute significantly to achieving NASA safety and affordability goals is Reliability and Maintainability (R&M) engineering. Inadequate reliability or failure of critical safety items may directly jeopardize the safety of the user(s) and result in a loss of life. Inadequate reliability of equipment may directly jeopardize mission success. Systems designed to be more reliable (fewer failures) and maintainable (fewer resources needed) can lower the total life cycle cost. The Department of Defense (DOD) and industry experience has shown that optimized and adequate levels of R&M are critical for achieving a high level of safety and mission success, and low sustainment cost. Also, lessons learned from the Space Shuttle program clearly demonstrated the importance of R&M engineering in designing and operating safe and affordable launch systems. The Challenger and Columbia accidents are examples of the severe impact of design unreliability and process induced failures on system safety and mission success. These accidents demonstrated the criticality of reliability engineering in understanding component failure mechanisms and integrated system failures across the system elements interfaces. Experience from the shuttle program also shows that insufficient Reliability, Maintainability, and Supportability (RMS) engineering analyses upfront in the design phase can significantly increase the sustainment cost and, thereby, the total life cycle cost. Emphasis on RMS during the design phase is critical for identifying the design features and characteristics needed for time efficient processing

Selection on Coding and Regulatory Variation Maintains Individuality in Major Urinary Protein Scent Marks in Wild Mice.

Directory of Open Access Journals (Sweden)

Michael J Sheehan

2016-03-01

Full Text Available Recognition of individuals by scent is widespread across animal taxa. Though animals can often discriminate chemical blends based on many compounds, recent work shows that specific protein pheromones are necessary and sufficient for individual recognition via scent marks in mice. The genetic nature of individuality in scent marks (e.g. coding versus regulatory variation and the evolutionary processes that maintain diversity are poorly understood. The individual signatures in scent marks of house mice are the protein products of a group of highly similar paralogs in the major urinary protein (Mup gene family. Using the offspring of wild-caught mice, we examine individuality in the major urinary protein (MUP scent marks at the DNA, RNA and protein levels. We show that individuality arises through a combination of variation at amino acid coding sites and differential transcription of central Mup genes across individuals, and we identify eSNPs in promoters. There is no evidence of post-transcriptional processes influencing phenotypic diversity as transcripts accurately predict the relative abundance of proteins in urine samples. The match between transcripts and urine samples taken six months earlier also emphasizes that the proportional relationships across central MUP isoforms in urine is stable. Balancing selection maintains coding variants at moderate frequencies, though pheromone diversity appears limited by interactions with vomeronasal receptors. We find that differential transcription of the central Mup paralogs within and between individuals significantly increases the individuality of pheromone blends. Balancing selection on gene regulation allows for increased individuality via combinatorial diversity in a limited number of pheromones.

2016-06-01

This study explores the way groups cope with collective responsibility for ecological problems. The social representations approach was adopted, and the collective symbolic coping model was used as a frame of analysis, integrating collective emotions to enhance the understanding of coping processes. The original feature of this study is that the analysis is at group level. Seven focus groups were conducted with French students. An original use of focus groups was proposed: Discussions were structured to induce feelings of collective responsibility and enable observation of how groups cope with such feelings at various levels (social knowledge; social identities; group dynamics). Two analyses were conducted: Qualitative analysis of participants' use of various kinds of knowledge, social categories and the group dynamics, and lexicometric analysis to reveal how emotions varied during the different discussion phases. Results showed that groups' emotional states moved from negative to positive: They used specific social categories and resorted to shared stereotypes to cope with collective responsibility and maintain the integrity of their worldview. Only then did debate become possible again; it was anchored in the nature-culture dichotomy such that groups switched from group-based to system-based emotions. © 2015 The British Psychological Society.

Full Text Available ABSTRACT OBJECTIVE: To evaluate whether the good and excellent functional results from arthroscopic repair of massive rotator cuff tears are maintained over the long term. METHODS: From the sample of the study conducted by our group in 2006, in which we evaluated the functional results from arthroscopic repair of massive rotator cuff tears, 35 patients were reassessed, 8 years after the first evaluation. The inclusion criteria were that these patients with massive rotator cuff tears operated by means of an arthroscopic technique, who participated in the previous study and achieved good or excellent outcomes according to the UCLA criteria. Patients whose results were not good or excellent in the first evaluation according to the UCLA criteria were excluded. RESULTS: Among the 35 patients reassessed, 91% of them continued to present good and excellent results (40% excellent and 51% good, while 3% presented fair results and 6% poor results. The time interval between the first and second evaluations was 8 years and the minimum length of follow-up since the immediate postoperative period was 9 years (range: 9-17 years, with an average of 11.4 years. CONCLUSION: The good and excellent results from arthroscopic repair of massive rotator cuff tears were mostly maintained (91%, with the same level of function and satisfaction, even though 8 years had passed since the first assessment, with a follow-up period averaging 11.4 years.

Rassias, Athos J; Guyre, Paul M; Yeager, Mark P

2011-12-01

We evaluated the differential impact of stress-associated vs high pharmacologic concentrations of hydrocortisone pretreatment on heart rate variability (HRV) during a subsequent systemic inflammatory stimulus. Healthy volunteers were randomized to receive placebo (Control) and hydrocortisone at 1.5 μg/kg per minute (STRESS) or at 3.0 μg/kg per minute (PHARM) as a 6-hour infusion. The STRESS dose was chosen to replicate the condition of physiologic adrenal cortical output during acute systemic stress. The PHARM dose was chosen to induce a supraphysiologic concentration of cortisol. The next day, all subjects received 2 ng/kg Escherichia coli endotoxin (lipopolysaccharide). Heart rate variability was analyzed with the statistic approximate entropy (ApEn). A lower ApEn correlates with decreased HRV. At the 3-hour nadir, the decrease in ApEn in the STRESS group was significantly less compared to placebo (P statistically different. We also found that the maximal decrease in ApEn preceded maximal increase in heart rate in all groups. The decrease in R-R interval was maximal at 4 hours, whereas the ApEn nadir was 1 hour earlier at 3 hours. Pretreatment with a stress dose of hydrocortisone but not a higher pharmacologic dose maintained a significantly higher ApEn after endotoxin exposure when compared to a placebo. In addition, decreases in ApEn preceded increases in heart rate. Copyright © 2011 Elsevier Inc. All rights reserved.

What distinguishes weight loss maintainers of the German Weight Control Registry from the general population?

2015-05-01

Differences between successful long-term weight loss maintainers and the general population with regard to eating and weighing habits, non-normative eating behaviors, and eating-related and general psychopathological parameters are unknown. Self-identified weight loss maintainers from the German Weight Control Registry (GWCR, n = 494) were compared with a representative sample of the general German population (n = 2,129). The samples did not differ in current BMI. Using the same assessment instruments in both cohorts, a variety of eating-related and psychological variables were determined. The GWCR participants reported more self-weighing and higher eating frequency but less hot meal consumption and more eating-out-of-home. Binge eating, compensatory behaviors, and concerns about shape and weight were reported more often by successful weight loss maintainers. Scores of depression and worrying about health were slightly higher whereas severity of somatic symptoms was less pronounced in the GWCR participants. Overall, our data suggest that successful weight loss maintainers are characterized by more concerns about shape and weight, greater binge eating frequency, and higher use of compensatory behaviors. The latter suggests that weight loss maintenance might not only be achieved by healthy strategies but also by non-normative behaviors which might increase the vulnerability for weight regain. © 2015 The Obesity Society.

A new era of prosperity through power : maintaining BC's competitive advantage

Energy Technology Data Exchange (ETDEWEB)

Potts, D. [BC Council of Forest Industries, Vancouver, BC (Canada)

2001-08-17

The availability of abundant low cost electric power has been a driving force behind British Columbia's economic growth. BC's low cost power resources can create a natural competitive economic advantage for the province. Electricity, as a publicly owned resource can offer many competitive advantages for business in British Columbia, if managed correctly. However, it was noted that meaningful economic advantages can only be realized if the existing power resources in the province are operated efficiently and priced at or close to cost. In the 1980s, the Joint Industry Electricity Steering Committee (JIESC) was formed following the regulation of BC Hydro by BC Utilities Commission. It became clear that maintaining low rates for electricity was a public issue that needed input from other governmental forums if JIESC was to be successful. The major sectors represented by JIESC include pulp and paper, mining, and electrochemicals. This paper listed each member company. In order to turn BC's economy around and re-establish the province as a leading economy in Canada, the following recommendations have been proposed for the short term: (1) maintain an ample supply of low cost power for the future, (2) remove the provincial sales tax on the purchase of electric power used for manufacturing and processing, (3) extend the current rate freeze, (4) initiate a long-term resource acquisition and transmission expansion strategy to assure the availability of ample supplies of low cost power. Recommendations for the long term include: (1) maintain regulated cost based rates, (2) develop ample low cost power, (3) utilize downstream benefits, (4) provide a role for the private sector, (5) maintain adequate transmission facilities, (6) reduce government revenues, and (7) instill customer driven management. 3 figs.

The interferometers composed of optical fibers are due to its high sensitivity capable of to measure various influences affecting the fiber. These influences may be bending or different sorts of fiber deformations, vibration, temperature, etc. In this case the vibration is the measured quantity, which is evaluated by analyzing the interference fringes representing changes in the fiber. Was used a Mach-Zehnder interferometer composed of the polarization maintaining elements. The polarization maintaining elements were used because of high sensitivity to polarization state inside the interferometer. The light was splitted into the two optical paths, where the first one is the reference fiber and it is separated from the actual phenomenon, and the second one is measuring fiber, which is directly exposed to vibration transmission from the underlying surface. The light source was narrowband DFB laser serating at a wavelength of 1550nm and as a detector an InGaAs PIN photodiode were used in this measurement. The electrical signal from the photodiode was amplified and fed into the measuring card. On the incoming signal the FFT was applied, which performs the transformation into the frequency domain and the results were further evaluated by software. We were evaluating the characteristic frequencies and their amplitude ratios. The frequency responses are unique for a given phenomenon, thus it is possible to identify recurring events by the characteristic frequencies and their amplitude ratios. The frequency range was limited by the properties of the used speaker, by the frequency characteristics of the filter in the amplifier and used resonant element. For the experiment evaluation the repeated impact of the various spherical objects on the surface board was performed and measured. The stability of amplitude and frequency and also the frequency range was verified in this measurement.

Cost-effective solutions to maintaining smart grid reliability

Science.gov (United States)

Qin, Qiu

As the aging power systems are increasingly working closer to the capacity and thermal limits, maintaining an sufficient reliability has been of great concern to the government agency, utility companies and users. This dissertation focuses on improving the reliability of transmission and distribution systems. Based on the wide area measurements, multiple model algorithms are developed to diagnose transmission line three-phase short to ground faults in the presence of protection misoperations. The multiple model algorithms utilize the electric network dynamics to provide prompt and reliable diagnosis outcomes. Computational complexity of the diagnosis algorithm is reduced by using a two-step heuristic. The multiple model algorithm is incorporated into a hybrid simulation framework, which consist of both continuous state simulation and discrete event simulation, to study the operation of transmission systems. With hybrid simulation, line switching strategy for enhancing the tolerance to protection misoperations is studied based on the concept of security index, which involves the faulted mode probability and stability coverage. Local measurements are used to track the generator state and faulty mode probabilities are calculated in the multiple model algorithms. FACTS devices are considered as controllers for the transmission system. The placement of FACTS devices into power systems is investigated with a criterion of maintaining a prescribed level of control reconfigurability. Control reconfigurability measures the small signal combined controllability and observability of a power system with an additional requirement on fault tolerance. For the distribution systems, a hierarchical framework, including a high level recloser allocation scheme and a low level recloser placement scheme, is presented. The impacts of recloser placement on the reliability indices is analyzed. Evaluation of reliability indices in the placement process is carried out via discrete event

In this study we evaluated a social skills group which employed a progressive applied behavior analysis model for individuals diagnosed with autism spectrum disorder. A randomized control trial was utilized; eight participants were randomly assigned to a treatment group and seven participants were randomly assigned to a waitlist control group. The social skills group consisted of 32, 2 h sessions. Teachers implemented a variety of behaviorally based procedures. A blind evaluator measured participants' behavior immediately prior to intervention, immediately following intervention, and during 16 and 32-week maintenance probes. Results of the study demonstrated that participants made significant improvements with their social behavior (p < .001) following intervention, and the results were maintained up to 32 weeks after intervention had concluded.

RETHINKING THE ROLE OF SMALL-GROUP COLLABORATORS AND ADVERSARIES IN THE LONDON KLEINIAN DEVELOPMENT (1914-1968).

Aguayo, Joseph; Regeczkey, Agnes

The authors historically situate the London Kleinian development in terms of the small-group collaborations and adversaries that arose during the course of Melanie Klein's career. Some collaborations later became personally adversarial (e.g., those Klein had with Glover and Schmideberg); other adversarial relationships forever remained that way (with A. Freud); while still other long-term collaborations became theoretically contentious (such as with Winnicott and Heimann). After the Controversial Discussions in 1944, Klein marginalized one group of supporters (Heimann, Winnicott, and Riviere) in favor of another group (Rosenfeld, Segal, and Bion). After Klein's death in 1960, Bion maintained loyalty to Klein's ideas while quietly distancing his work from the London Klein group, immigrating to the United States in 1968. © 2016 The Psychoanalytic Quarterly, Inc.

Strategies are needed to ensure that the U.S. Government meets its goals for improving the health of the nation (e.g., Healthy People 2020). To date, progress toward these goals has been undermined by a set of discernible challenges: People lack sufficient motivation, they frequently fail to translate healthy intentions into action, their efforts are undermined by the persistence of prior unhealthy habits, and they have considerable difficulty maintaining new healthy patterns of behavior. Guided by advances in psychological science, we provide innovative, evidence-based policies that address each of these challenges and, if implemented, will enhance people's ability to create and maintain healthy behavioral practices. © The Author(s) 2015.

Local knowledge held by farmers in Eastern Tyrol (Austria) about the use of plants to maintain and improve animal health and welfare.

The sustainable management of animal health and welfare is of increasing importance to consumers and a key topic in the organic farming movement. Few systematic studies have been undertaken investigating farmers' local knowledge related to this issue. Ethnoveterinary medicine (EVM) is a discipline focusing on local knowledge and folk methods in veterinary medicine, however most ethnoveterinarian studies primarily address the treatment of animal diseases. Very few studies have explored prophylactic methods. An ethnoveterinary research project in Eastern Tyrol (Austria) was conducted in 2004 and 2005 to gather information about local knowledge of animal husbandry from 144 informants, with the emphasis on plants that maintain livestock health and welfare. Informants mentioned a total of 87 plants and 22 plant-based generic terms in the context of maintaining and improving livestock health and welfare. The most important preventive measures for maintaining and improving animal health and welfare were practices related to "fodder" and "feeding". In this category the plants mentioned could be grouped according to three different perceptions about their effect on animals: "Good or bad fodder", "Functional fodder" and "Fodder medicine". In addition to fodder, environmental management, the human-animal relationship, household remedies and cultural/religious activities were also mentioned. When asked about practices in the past that maintained animal health and well-being, interviewees mentioned, for example, the importance of the diversity of sources that used to be available to obtain feed and fodder. The informants' approach that feeding is central to livestock welfare is in line with the standard scientific literature on animal health, including in organic farming. Various scientific studies into common fodder evaluate the nutritive and dietary value, efficiency and safety of fodder. Future studies also have to consider the evaluation of traditional, local fodder

Antihypertrophic Effects of Small Molecules that Maintain Mitochondrial ATP Levels Under Hypoxia

Directory of Open Access Journals (Sweden)

Hiroaki Nagai

2017-10-01

Full Text Available Since impaired mitochondrial ATP production in cardiomyocytes is thought to lead to heart failure, a drug that protects mitochondria and improves ATP production under disease conditions would be an attractive treatment option. In this study, we identified small-molecule drugs, including the anti-parasitic agent, ivermectin, that maintain mitochondrial ATP levels under hypoxia in cardiomyocytes. Mechanistically, transcriptomic analysis and gene silencing experiments revealed that ivermectin increased mitochondrial ATP production by inducing Cox6a2, a subunit of the mitochondrial respiratory chain. Furthermore, ivermectin inhibited the hypertrophic response of human induced pluripotent stem cell-derived cardiomyocytes. Pharmacological inhibition of importin β, one of the targets of ivermectin, exhibited protection against mitochondrial ATP decline and cardiomyocyte hypertrophy. These findings indicate that maintaining mitochondrial ATP under hypoxia may prevent hypertrophy and improve cardiac function, providing therapeutic options for mitochondrial dysfunction.

Self-guided Change: The most common form of long-term, maintained health behavior change

Science.gov (United States)

Bishop, F Michler

2018-01-01

Millions of people change risky, health-related behaviors and maintain those changes. However, they often take years to change, and their unhealthy behaviors may harm themselves and others and constitute a significant cost to society. A review—similar in nature to a scoping review—was done of the literature related to long-term health behavior change in six areas: alcohol, cocaine and heroin misuse, gambling, smoking, and overeating. Based on the limited research available, reasons for change and strategies for changing and for maintaining change were also reviewed. Fifty years of research clearly indicate that as people age, in the case of alcohol, heroin and cocaine misuse, smoking, and gambling, 80–90 percent moderate or stop their unhealthy behaviors. The one exception is overeating; only 20 percent maintain their weight loss. Most of these changes, when they occur, appear to be the result of self-guided change. More ways to accelerate self-guided, health-related behavior change need to be developed and disseminated. PMID:29375888

An ideal occlusion with proper tooth alignment and fully functional teeth is the ultimate goal of all dental treatments. Premature extraction of deciduous teeth is a common sequeale of untreated dental caries in teeth in which the damage is far beyond repair. Premature extraction might lead to loss of space for the successor tooth, drifting of teeth and loss of arch integrity leading to malocclusion in the permanent teeth. To prevent the space loss, space maintainers are designed and delivered at the time of extraction to allow for development of proper functional occlusion in children till the eruption of the succedaneous permanent tooth. A six-year-old female patient with chronic intra-radicular abscess in upper right first primary molar was treated with extraction followed by the placement of BruxZir zirconia space maintainer. Clinical and radiographic examinations were performed at one and six months. At the end of six months, the patient was completely asymptomatic and there were no visible signs of gingival inflammation and tissue irritation at the site of the space maintainer.

2017-10-01

Full Text Available A good understanding of organizational constraints is vital to facilitate organizational development as the sustainable development of organizations can be constrained by the organization itself. In this study, bibliometric methods were adopted to investigate the research status and trends of organizational constraints. The findings showed that there were 1138 articles and reviews, and 52 high-frequency keywords related to organizational constraints during the period 1980–2016. The research cores were “constraints”, “learning”, “institution”, and “behavior” in the co-occurrence network, and “constraints” played the most significant role. The 52 high-frequency keywords were classified into six clusters: “change and decision-making”, “supply chain and sustainability”, “human system and performance”, “culture and relations”, “entrepreneur and resource”, and “learning and innovation”. Furthermore, the indicators of organizational development (e.g., innovation, supply chain, decision-making, performance, sustainability, and employee behavior were found to be significantly related to the organizational constraints. Based on these findings, future trends were proposed to maintain the sustainability of organizations. This study investigated the state of the art in terms of organizational constraints and provided valuable references for maintaining the sustainable development of organizations.

Astrocytic glycogen-derived lactate fuels the brain during exhaustive exercise to maintain endurance capacity.

Brain glycogen stored in astrocytes provides lactate as an energy source to neurons through monocarboxylate transporters (MCTs) to maintain neuronal functions such as hippocampus-regulated memory formation. Although prolonged exhaustive exercise decreases brain glycogen, the role of this decrease and lactate transport in the exercising brain remains less clear. Because muscle glycogen fuels exercising muscles, we hypothesized that astrocytic glycogen plays an energetic role in the prolonged-exercising brain to maintain endurance capacity through lactate transport. To test this hypothesis, we used a rat model of exhaustive exercise and capillary electrophoresis-mass spectrometry-based metabolomics to observe comprehensive energetics of the brain (cortex and hippocampus) and muscle (plantaris). At exhaustion, muscle glycogen was depleted but brain glycogen was only decreased. The levels of MCT2, which takes up lactate in neurons, increased in the brain, as did muscle MCTs. Metabolomics revealed that brain, but not muscle, ATP was maintained with lactate and other glycogenolytic/glycolytic sources. Intracerebroventricular injection of the glycogen phosphorylase inhibitor 1,4-dideoxy-1,4-imino-d-arabinitol did not affect peripheral glycemic conditions but suppressed brain lactate production and decreased hippocampal ATP levels at exhaustion. An MCT2 inhibitor, α-cyano-4-hydroxy-cinnamate, triggered a similar response that resulted in lower endurance capacity. These findings provide direct evidence for the energetic role of astrocytic glycogen-derived lactate in the exhaustive-exercising brain, implicating the significance of brain glycogen level in endurance capacity. Glycogen-maintained ATP in the brain is a possible defense mechanism for neurons in the exhausted brain.

Being a member of a peer group involves making decisions about whom to include in or exclude from the group. Sometimes these decisions are related to whether members of the group support or challenge the norms of the group. To examine how young children weigh concerns for group norms and group membership in both moral and social-conventional norm contexts, children (3- to 6-year-olds; N=73) were asked to decide between including an ingroup member who challenged the group's norm or an outgroup member who supported the norm. Groups held either moral (equal or unequal resource allocation) or social-conventional (traditional or nontraditional) norms. In the moral contexts, children were more likely to include the peer who advocated for the moral concern for equality regardless of the peer's group membership or their group's specific norm. In the social-conventional contexts, however, children were more likely to include the peer who advocated for the conventional concern for maintaining traditions but only at the group-specific level. Furthermore, with age children increasingly based their inclusion decisions on normative concerns, rather than on group membership concerns, and differed in their inclusion decisions for ingroups and outgroups. Finally, children reasoned about their decisions by referencing concerns for fairness, group norms, and group membership, suggesting that preschool children weigh multiple concerns when deciding whom to include in their groups. Overall, the current study revealed differences in how preschool children weigh moral and social-conventional concerns in intergroup contexts. Copyright © 2017 Elsevier Inc. All rights reserved.

Soppera, A.; Burbridge, T.

During the 1980s, Mark Weiser [1] predicted a world in which computing was so pervasive that devices embedded in the environment could sense their relationship to us and to each other. These tiny ubiquitous devices would continually feed information from the physical world into the information world. Twenty years ago, this vision was the exclusive territory of academic computer scientists and science fiction writers. Today this subject has become of interest to business, government, and society. Governmental authorities exercise their power through the networked environment. Credit card databases maintain our credit history and decide whether we are allowed to rent a house or obtain a loan. Mobile telephones can locate us in real time so that we do not miss calls. Within another 10 years, all sorts of devices will be connected through the network. Our fridge, our food, together with our health information, may all be networked for the purpose of maintaining diet and well-being. The Internet will move from being an infrastructure to connect computers, to being an infrastructure to connect everything [2, 3].

Full Text Available Ecological security and environmental sustainability are the foundations of sustainable development. With the acceleration of urbanization, increasing human activities have promoted greater impacts on the eco-spaces that maintain ecological security. Regional key eco-space has become the primary need to maintain environmental sustainability and can offer society with continued ecosystem services. In this paper, considering the security of water resources, biodiversity conservation, disaster avoidance and protection and natural recreation, an integrated index of eco-space importance was established and a method for identifying key eco-space was created using GIS, with Lanzhou City, China as a case study. The results show that the area of core eco-space in the Lanzhou City is approximately 50,908.7 hm2, accounting for 40% of the region’s total area. These areas mainly consist of geological hazard protection zones and the core zones of regional river systems, wetlands, nature reserves, forest parks and scenic spots. The results of this study provide some guidance for the management of ecological security, ecological restoration and environmental sustainability.

Untreated patients with congenital growth hormone deficiency (GHD) and IGF-I deficiency are characterized not only by dwarfism but also by acromicria and organomicria, such as the heart. We assessed cardiac dimensions and function in very young patients with Laron syndrome (LS) undergoing IGF-I replacement therapy. Two to seven echocardiographic measurements were performed during IGF-I replacement therapy on male (n=4) and female (n=4) LS -patients, mean+/-SD age of 7.1+/-3.6 years (range 1.6-11.6 years), weight 16.1+/-9.7 kg, and height 89.9+/-18.5 cm. As aged- and gender-matched controls served 44 healthy children, age: 8.7+/-5.5 years, weight: 36.1+/-22.4 kg, and height: 129.7+/-33.1cm. Data of LS patients were normalized to body surface area and compared to the control group as well as nomograms of normal echocardiographic parameters for this age group. Left ventricular diastolic and systolic dimensions (LVDD/ LVSD, mm) and LV mass (gr) were significantly smaller in boys and girls with IGF-I treated LS compared with controls while the shortening fraction (%) and intraventricular septum thickness (mm) were similar. When compared with standard values for this age group, all treated LS patients were within 1 standard deviation of the mean. IGF-I therapy of young patients with Laron syndrome maintain LV dimensions and function within the normal range of aged-matched controls.

Previous research has shown that the selective remembering of a speaker and the resulting silences can cause forgetting of related, but unmentioned information by a listener (Cuc, Koppel, & Hirst, 2007). Guided by more recent work that demonstrated both detrimental and beneficial effects of selective memory retrieval in individuals, the present research explored the effects of selective remembering in social groups when access to the encoding context at retrieval was maintained or impaired. In each of three experiments, selective retrieval by the speaker impaired recall of the listener when access to the encoding context was maintained, but it improved recall of the listener when context access was impaired. The results suggest the existence of two faces of selective memory retrieval in social groups, with a detrimental face when the encoding context is still active at retrieval and a beneficial face when it is not. The role of silence in social recall thus seems to be more complex than was indicated in prior work, and mnemonic silences on the part of a speaker can be "golden" for the memories of a listener under some circumstances, but not be "golden" under others.

Continuing professional education (CPE) plays an important role in continuing professional development of pharmacists for providing quality pharmaceutical care but also to maintain professional and organizational vitality and meet changing community/population needs. The study objective was to describe and understand factors of importance in selection of CPE credit hours among Upper Midwest pharmacists. A cross-sectional study of licensed pharmacists ( n = 1239) in Iowa, Minnesota, Nebraska, North Dakota, and South Dakota included completion of a questionnaire on demographics and CPE decision-making. Factor analysis, t -test, and multivariate analyses were performed using Stata 10.1. Pharmacists placed greatest importance on maintaining licensure (mean = 2.72/3.00), personal interest (mean = 2.57), and self-improvement (mean = 2.42). Community/population need (mean = 1.83) was rated as slightly more important ( p market, but more importantly to ensure continued provision of quality pharmaceutical care and patient education.

Effects of intergroup upward comparison, trait self-esteem, and identity shift on state self-esteem and affect in upward comparison with in-group members

2006-01-01

The present study investigated factors that protect people low in trait self-esteem (Low-SEs), who may be less skilled at constructing information in self-enhancing manners, from threats after interpersonal upward comparison with in-group members. We hypothesized that even Low-SEs can maintain their state self-esteem under intergroup upward comparison. Furthermore, this study explored the possibility that individuals used identity-shift, a strategy to maintain their personal identity, even in...

In Bangladesh, cholera is endemic and maintains a regular seasonal pattern. The role of phytoplankton in maintaining endemicity and seasonality of cholera was monitored in Matlab, Bangladesh. Phytoplankton and water samples were collected from two ponds bi-weekly for 1 year. The association of Vibrio cholerae O1 with phytoplankton was studied by culture and direct fluorescent antibody techniques. The bio-physicochemical parameters of water were measured and data for cases of cholera were collected from the records of Matlab hospital. The correlation of cholera cases with levels of phytoplankton, V. cholerae and bio-physicochemical parameters of water was carried out using Pearson's correlation coefficients. V. cholerae O1 survived for 48 days in association with Anabaena variabilis in a culturable state, but survived for a year in a viable but non-culturable (VBNC) state. V. cholerae survived for 12 and 32 days in a culturable state in control water (without algae) and water with algae, respectively. There was a significant correlation between changing levels of cholera cases in the community and the blue green algae and total phytoplankton in the aquatic environment. A significant correlation was also found between the cholera cases and chlorophyll-a and VBNC V. cholerae O1 in the aquatic environment. This study demonstrated the role of phytoplankton in maintaining endemicity and seasonality of cholera in Bangladesh. © The Author 2015.

To evaluate treatment decision-making with respect to maintaining periodontally compromised teeth among dentists with or without postgraduate qualifications in implant dentistry. A series of patient scenarios with varying degrees of periodontal disease levels was presented to dental practitioners. Practitioners' decision-making outcome was determined, and intention to retain the compromised teeth was analyzed in bivariate and regression analyses (accounting for postgraduate implant training, gender, years in dental practice, and implant placement experience). This study involved 30 dental practitioners with postgraduate implant qualifications (GDPP), 33 dental practitioners without postgraduate implant qualifications (GDP), and 27 practitioners undergoing training for postgraduate implant qualifications (GDPT). Variations in treatment decision-making were evident between the three groups. Differences in treatment approaches to retaining compromised teeth were apparent. Furthermore, variations in rehabilitation of extracted scenarios existed in terms of use of implant and number of implants need for rehabilitation. Accounting for dentist and practice factors in regression analyses, GDPP/GDPT were three times as likely to retain periodontally compromised upper molar, with or without pain, compared to GDP (without pain OR 3.10, 95%CI 1.04, 10.62 P = 0.04; with pain OR 3.08, 95%CI 1.09, 8.14 P = 0.03). Variations in treatment decision-making with respect to retaining periodontally compromised teeth exist between dental practitioners with and those without postgraduate training in implant dentistry. Furthermore differences in management approaches in how they would retain the teeth or rehabilitate the dental arch were apparent. © 2013 John Wiley & Sons A/S.

Previous studies have reported that exercise decreases cocaine self-administration in rats with long-term access (8+ weeks) to activity wheels in the home cage. The purpose of this study was to (a) examine the importance of the temporal relationship between physical activity and initial drug exposure, (b) determine the effects of exercise on responding maintained by a nondrug reinforcer (i.e., food), and (c) investigate the effects of exercise on cocaine-induced increases in locomotor activity. To this end, female rats were obtained at weaning and divided into 4 groups: (a) EXE-SED rats were housed in exercise cages for 6 weeks and then transferred to sedentary cages after the first day of behavioral testing; (b) SED-EXE rats were housed in sedentary cages for 6 weeks and then transferred to exercise cages after the first day of behavioral testing; (c) SED-SED rats remained in sedentary cages for the duration of the study; and (d) EXE-EXE rats remained in exercise cages for the duration of the study. Relative to the sedentary group (SED-SED), exercise reduced cocaine self-administration in both groups with access to activity wheels after initial drug exposure (EXE-EXE, SED-EXE) but did not reduce cocaine self-administration in the group with access to activity wheels only before drug exposure (EXE-SED). Exercise also decreased the effects of cocaine on locomotor activity but did not reduce responding maintained by food. These data suggest that exercise may reduce cocaine use in drug-experienced individuals with no prior history of aerobic activity without decreasing other types of positively reinforced behaviors.

During pregnancy, glycine and serine become more important because they are the primary suppliers of methyl groups for the synthesis of fetal DNA, and more glycine is required for fetal collagen synthesis as pregnancy progresses. In an earlier study, we reported that glycine flux decreased by 39% from the first to the third trimester in pregnant adolescent girls. As serine is a primary precursor for glycine synthesis, the objective of this study was to measure and compare glycine and serine fluxes and inter-conversions in pregnant adolescent girls and adult women in the first and third trimesters. Measurements were made after an overnight fast by continuous intravenous infusions of 2H2-glycine and 15N-serine in eleven adolescent girls (17·4 (se 0·1) years of age) and in ten adult women (25·8 (se 0·5) years of age) for 4 h. Adolescent girls had significantly slower glycine flux and they made less glycine from serine in the third (Padolescent girls (P=0·04) and was significantly associated with third trimester glycine flux. These findings suggest that the pregnant adolescent cannot maintain glycine flux in late pregnancy compared with early pregnancy because of decreased synthesis from serine. It is possible that the inability to maintain glycine synthesis makes her fetus vulnerable to impaired cartilage synthesis, and thus linear growth.

To examine the feasibility and patterns of effectiveness of a breast cancer support group intervention specifically designed to facilitate self-transcendence views and perspectives that would enhance emotional and physical well-being. Pre-experimental design pilot intervention study with a quantitative approach to data analysis. Survivor-established breast cancer resource center in Austin, TX. Women with recently diagnosed breast cancer (N = 16) participating in 90-minute support group sessions that met weekly for eight weeks. Theory-driven support group intervention facilitated by an oncology clinical nurse specialist, a psychotherapist, and a breast cancer survivor. Activities planned for individual sessions were based on self-transcendence theory, cancer support group literature, and the facilitators' extensive previous support group experience. Self-transcendence, emotional well-being, physical well-being. Good networking, coordination, and follow-up were essential for participant recruitment and retention throughout the intervention period. Although specific theory-driven activities were planned for group sessions, facilitators maintained flexibility in meeting immediate concerns of the participants. Relationships among participants' scores on study variables indicated an association between self-transcendence and emotional well-being. Scores on self-transcendence and well-being variables at the end of the intervention increased from baseline, but only functional performance status, mood state, and satisfaction with life reached statistical significance. The pilot study was invaluable in providing direction for the conduct of future experimental studies. Provides preliminary support for the use of theory-driven activities for promotion of self-transcendence views and behaviors within a cancer support group setting.

How Local Landholder Groups Collectively Manage Weeds in South-Eastern Australia

Science.gov (United States)

Graham, Sonia; Rogers, Sarah

2017-09-01

For two decades researchers and policy makers have been arguing that community-based collective action is needed to effectively control weeds. Yet there has been little social research into the ways that collective weed control emerges at local scales. The aim of this paper is to investigate the mechanisms through which three local landholder groups in south-eastern Australia collectively manage weeds and the measures they use to evaluate success. Semi-structured interviews were conducted with members of three Landcare groups—Jerrawa Creek/Upper Lachlan, MacLaughlin River and Towamba Valley—as well as government staff external to the groups. The results reveal that for all three groups collective weed control is about supporting individual weed control efforts as well as proactively engaging landholders with the worst infestations. The groups were seen to be successful because they focused on the common challenge that weeds pose to all landholders, thereby removing the shame associated with having weeds, and because they organised community events that were as much about building and maintaining social relationships as improving weed control. Groups were positive about what they had achieved as collectives of landholders, but also saw an important role for government in providing funding, engaging with landholders who were unwilling to engage directly with the group, and controlling weeds on public lands.

As the 21st century progresses, new nuclear facilities and the expansion of nuclear activities into new countries will require the International Atomic Energy Agency (IAEA) to place a higher reliance on attaining and maintaining a Continuity of Knowledge (CoK) of its safeguards information than is currently practiced. Additionally, a conceptual view of where and how CoK can be applied will need to evolve to support improved efficiency and efficacy of drawing a safeguards conclusion for each Member State. The ability to draw a safeguards conclusion for a Member State will be predicated on the confidence that CoK has been attained and subsequently maintained with respect to the data and information streams used by the IAEA. This confidence can be described as a function of factors such as elapsed time since the measurement, surveillance of attributes, authentication of information, historic knowledge of potential system failures, and the number and type of data collections. A set of general scenarios are further described for determining what is required to attain CoK and whether CoK has been maintained. A high-level analysis of example scenarios is presented to identify failures or gaps that could cause a loss of CoK. Potential areas for technological research and development are discussed for the next generation of CoK tools.

Religious attitudes toward nuclear energy: an analysis of statements by religious groups

International Nuclear Information System (INIS)

Smith, J.A. III.

1983-01-01

This dissertation analyzes selected responses of religious groups to the question, Should society increase or decrease its reliance on energy produced by nuclear fission and for what reasons. The primary sources, dating from 1974 until mid-1980, are 82 official or semi-official statements and study documents of religious groups and 17 shareholder resolutions filed by religious groups. The groups are primarily from the United States, Canada, and Great Britain or related to the World Council of Churches. The thesis of the study is that a fully adequate religious statement about nuclear energy would show awareness of and deal with the questions raised in the analytical framework. Using that framework, there are few, if any, adequate religious statements about nuclear energy. A typology of ethical modes in Chapter V describes five positions: polemical anti-nuclear, dialogical anti-nuclear, dialogical middle, dialogical pro-nuclear, and polemical pro-nuclear. The bias of the study is to maintain open and rational discourse with all perspectives rather than to take a position for or against nuclear energy. The study primarily analyzes how religious groups deal with one complex social issue, nuclear energy, but the analytical framework has broad application to a variety of social issues as treated by religious groups

Coupled Proliferation and Apoptosis Maintain the Rapid Turnover of Microglia in the Adult Brain

Full Text Available Summary: Microglia play key roles in brain development, homeostasis, and function, and it is widely assumed that the adult population is long lived and maintained by self-renewal. However, the precise temporal and spatial dynamics of the microglial population are unknown. We show in mice and humans that the turnover of microglia is remarkably fast, allowing the whole population to be renewed several times during a lifetime. The number of microglial cells remains steady from late postnatal stages until aging and is maintained by the spatial and temporal coupling of proliferation and apoptosis, as shown by pulse-chase studies, chronic in vivo imaging of microglia, and the use of mouse models of dysregulated apoptosis. Our results reveal that the microglial population is constantly and rapidly remodeled, expanding our understanding of its role in the maintenance of brain homeostasis. : The mechanism or mechanisms underlying microglial homeostasis are unknown. Askew et al. show that microglia self-renewal is maintained by coupled proliferation and apoptosis, resulting in a stable microglia number over a mouse or human lifetime.

A Group Neighborhood Average Clock Synchronization Protocol for Wireless Sensor Networks

Science.gov (United States)

Lin, Lin; Ma, Shiwei; Ma, Maode

2014-01-01

Clock synchronization is a very important issue for the applications of wireless sensor networks. The sensors need to keep a strict clock so that users can know exactly what happens in the monitoring area at the same time. This paper proposes a novel internal distributed clock synchronization solution using group neighborhood average. Each sensor node collects the offset and skew rate of the neighbors. Group averaging of offset and skew rate value are calculated instead of conventional point-to-point averaging method. The sensor node then returns compensated value back to the neighbors. The propagation delay is considered and compensated. The analytical analysis of offset and skew compensation is presented. Simulation results validate the effectiveness of the protocol and reveal that the protocol allows sensor networks to quickly establish a consensus clock and maintain a small deviation from the consensus clock.

Justifying group-specific common morality.

Science.gov (United States)

Strong, Carson

2008-01-01

Some defenders of the view that there is a common morality have conceived such morality as being universal, in the sense of extending across all cultures and times. Those who deny the existence of such a common morality often argue that the universality claim is implausible. Defense of common morality must take account of the distinction between descriptive and normative claims that there is a common morality. This essay considers these claims separately and identifies the nature of the arguments for each claim. It argues that the claim that there is a universal common morality in the descriptive sense has not been successfully defended to date. It maintains that the claim that there is a common morality in the normative sense need not be understood as universalist. This paper advocates the concept of group specific common morality, including country-specific versions. It suggests that both the descriptive and the normative claims that there are country-specific common moralities are plausible, and that a country-specific normative common morality could provide the basis for a country's bioethics.
