    Szasz and others have pointed out that many so-called voluntary admissions to mental hospitals have various elements of coercion involved, and are thus not truly voluntary. The author contends that the converse situation is also true, that many patients admitted under involuntary commitment papers arrange for their own commitments. Reasons for such choices are discussed in the context of a review of the literature and several case histories.

    The purpose of this study was to determine if inspiratory muscle training (IMT) alters the oxygen cost of breathing (Vo(2RM)) during voluntary hyperpnea. Sixteen male cyclists completed 6 wk of IMT using an inspiratory load of 50% (IMT) or 15% placebo (CON) of maximal inspiratory pressure (Pi(max)). Prior to training, a maximal incremental cycle ergometer test was performed to determine Vo(2) and ventilation (V(E)) at multiple workloads. Pre- and post-training, subjects performed three separate 4-min bouts of voluntary eucapnic hyperpnea (mimic), matching V(E) that occurred at 50, 75, and 100% of Vo(2 max). Pi(max) was significantly increased (P muscles following a period of IMT may facilitate increased O(2) availability to the active muscles during exercise. These data suggest that IMT may reduce the O(2) cost of ventilation during exercise, providing an insight into mechanism(s) underpinning the reported improvements in whole body endurance performance; however, this awaits further investigation.

    2013-08-01

    Although the word commitment is prevalent in conservation biology literature and despite the importance of people's commitment to the success of conservation initiatives, commitment as a psychological phenomenon and its operation in specific conservation behaviors remains unexplored. Despite increasing calls for conservation psychology to play a greater role in meeting conservation goals, applications of the psychological sciences to specific conservation behaviors, illustrating their utility to conservation practice, are rare. We examined conservation volunteers' motivations and commitment to urban conservation volunteering. We interviewed key informant volunteers and used interview findings to develop psychometric scales that we used to assess motivations and commitment to volunteer. We surveyed 322 urban conservation volunteers and used factor analysis to reveal how volunteers structure their motivations and commitment to volunteer for urban conservation activities. Six categories of motivations and 2 categories of commitment emerged from factor analysis. Volunteers were motivated by desires to help the environment, defend and enhance the ego, career and learning opportunities, escape and exercise, social interactions, and community building. Two forms of commitment, affective and normative commitment, psychologically bind people to urban conservation volunteerism. We used linear-regression models to examine how these categories of motivations influence volunteers' commitment to conservation volunteerism. Volunteers' tendency to continue to volunteer for urban conservation, even in the face of fluctuating counter urges, was motivated by personal, social, and community functions more than environmental motivations. The environment, otherwise marginally important, was a significant motivator of volunteers' commitment only when volunteering met volunteers' personal, social, and community-building goals. Attention to these personal, social, and community

    Full Text Available Corporate Social Responsibility has grown popular among discussions in economics and societies worldwide. To a growing extent customers make their buying decisions underCSR aspects. Enterprises try to follow up with CSR strategies. But often a gap has to be detected between the theoretical approach of CSR and practical implementations within the entrepreneurial reality. This article introduces a possible approach of closing the gap within CSR implementation. The ‘Heilbronn Declaration’ is a voluntary agreement of enterprises and institutions in Germany especially of the Heilbronn-Franconia region. The approach of the ‘Heilbronn Declaration’ targets the decisive factors of success or failure, the achievements of the implementation and best practices regarding CSR. A form of responsible entrepreneurship shall be initiated to meet the requirements of stakeholders’ trust in economy. Therefore it has been elaborated by academics together with enterprises and their shareholders. It is an approach to make voluntary commitment more binding. Its scientific base may allowdevelopment of indicators for CSR implementation in business ventures and institutions to finalize in a CSR audit. The innovative approach of the ‘Heilbronn Declaration’ is theintegration of the prospective signatories into discussion on the idea and purpose of business from the very first beginning.Keywords: sustainability, corporate social responsibility, innovation, voluntary commitment, authentic CSR, small and medium sized enterprises (SME

    The G8 is considering committing to purchase vaccines against diseases concentrated in low-income countries (if and when desirable vaccines are developed) as a way to spur research and development on vaccines for these diseases. Under such an 'advance market commitment,' one or more sponsors would commit to a minimum price to be paid per person immunized for an eligible product, up to a certain number of individuals immunized. For additional purchases, the price would eventually drop to close to marginal cost. If no suitable product were developed, no payments would be made. We estimate the offer size which would make revenues similar to the revenues realized from investments in typical existing commercial pharmaceutical products, as well as the degree to which various model contracts and assumptions would affect the cost-effectiveness of such a commitment. We make adjustments for lower marketing costs under an advance market commitment and the risk that a developer may have to share the market with subsequent developers. We also show how this second risk could be reduced, and money saved, by introducing a superiority clause to a commitment. Under conservative assumptions, we document that a commitment comparable in value to sales earned by the average of a sample of recently launched commercial products (adjusted for lower marketing costs) would be a highly cost-effective way to address HIV/AIDS, malaria, and tuberculosis. Sensitivity analyses suggest most characteristics of a hypothetical vaccine would have little effect on the cost-effectiveness, but that the duration of protection conferred by a vaccine strongly affects potential cost-effectiveness. Readers can conduct their own sensitivity analyses employing a web-based spreadsheet tool.

    2004-10-01

    The energetics of terrestrial locomotion are of considerable interest to ecologists and physiologists, but nearly all of our current knowledge comes from animals undergoing forced exercise. To explore patterns of energy use and behavior during voluntary exercise, we developed methods allowing nearly continuous measurements of metabolic rates in freely behaving small mammals, with high temporal resolution over periods of several days. We used this approach to examine relationships between ambient temperature (Ta), locomotor behavior and energy costs in the deer mouse, a small mammal that routinely encounters a large range of temperatures in its natural habitat. We tested for individual consistency in running behavior and metabolic traits, and determined how locomotor costs vary with speed and Ta. Because of the importance of thermoregulatory costs in small mammals, we checked for substitution of exercise heat for thermostatic heat production at Ta below the thermal neutral zone and determined the fraction of the daily energy budget comprising exercise costs. Locomotor behavior was highly variable among individuals but had high repeatability, at least over short intervals. We found few temperature-related changes in speed or distance run, but Ta strongly affected energy costs. Partial substitution of exercise heat for thermogenic heat occurred at low Ta. This reduced energy expenditure during low-temperature running by 23-37%, but running costs comprised a fairly minor fraction of the energy budget, so the daily energy savings via substitution were much smaller. Deer mice did not adjust running speed to maximize metabolic economy, as they seldom used the high speeds that provide the lowest cost of transport. The highest voluntary speeds (4-5 km h(-1)) were almost always below the predicted maximal aerobic speed, and were much less than the species' maximal sprint speed. Maximum voluntarily attained rates of oxygen consumption (VO2) were highest at low Ta, but rarely

    Full Text Available Scaling up voluntary medical male circumcision (VMMC for HIV prevention is cost saving and creates fiscal space in the future that otherwise would have been encumbered by antiretroviral treatment costs. An investment of US$1,500,000,000 between 2011 and 2015 to achieve 80% coverage in 13 priority countries in southern and eastern Africa will result in net savings of US$16,500,000,000. Strong political leadership, country ownership, and stakeholder engagement, along with effective demand creation, community mobilisation, and human resource deployment, are essential. This collection of articles on determining the cost and impact of VMMC for HIV prevention signposts the way forward to scaling up VMMC service delivery safely and efficiently to reap individual- and population-level benefits.

    As voluntary medical male circumcision (VMMC) programs scale up, there is a pressing need for information about the important cost drivers, and potential efficiency gains. We examine those cost drivers here, and estimate the potential efficiency gains through an econometric model. We examined the main cost drivers (i.e., personnel and consumables) associated with providing VMMC in sub-Saharan Africa along a number of dimensions, including facility type and service provider. Primary source facility level data from Kenya, Namibia, South Africa, Tanzania, Uganda, and Zambia were utilized throughout. We estimated the efficiency gains by econometrically estimating a cost function in order to calculate the impact of scale and other relevant factors. Personnel and consumables were estimated at 36% and 28%, respectively, of total costs across countries. Economies of scale (EOS) is estimated to be eight at the median volume of VMMCs performed, and EOS falls from 23 at the 25th percentile volume of VMMCs performed to 5.1 at the 75th percentile. The analysis suggests that there is significant room for efficiency improvement as indicated by declining EOS as VMMC volume increases. The scale of the fall in EOS as VMMC volume increases suggests that we are still at the ascension phase of the scale-up of VMMC, where continuing to add new sites results in additional start-up costs as well. A key aspect of improving efficiency is task sharing VMMC procedures, due to the large percentage of overall costs associated with personnel costs. In addition, efficiency improvements in consumables are likely to occur over time as prices and distribution costs decrease.

  15. Great Lakes waters: radiation dose commitments, potential health effects, and cost-benefit considerations

    Ainsworth, E.J.

    1977-07-01

    In 1972, a Great Lakes Water Quality Agreement was signed by the United States and Canadian Governments. It was stipulated that the operation and effectiveness of the agreement were to be reviewed comprehensively in 1977. Aspects of the agreement concern nondegradation of Great Lakes waters and maintenance of levels of radioactivity or other potential pollutants at levels considered as low as practicable. A refined radioactivity objective of one millirem is proposed in the Water Quality Agreement. The implications of adoption of this objective are not known fully. The Division of Environmental Impact Studies was commissioned by ERDA's Division of Technology Overview to summarize the information available on the current levels of radioactivity in Great Lakes waters, compute radiation-dose commitment (integrated dose over 50 years after consumption of 2.2 liters of water of one year), and to comment on the feasibility and cost-benefit considerations associated with the refined one-millirem objective. Current levels of radioactivity in the waters of Lakes Michigan, Ontario, Erie, and Huron result in dose commitments in excess of 1 mrem for whole body and 6 mrem for bone. Future projections of isotope concentrations in Great lakes water indicate similar dose commitments for drinking water in the year 2050. Reduction of the levels of radioactivity in Great Lakes waters is not feasible, but cost-benefit considerations support removal of /sup 226/Ra and /sup 90/Sr through interceptive technology before water consumption. Adoption of the one-millirem objective is not propitious.

  16. Looking forward and looking back: integrating completion and sunk-cost effects within an escalation-of-commitment progress decision.

    Moon, H

    2001-02-01

    Currently, there are 2 conflicting frameworks with which to understand why decision makers might escalate their commitment to a previously chosen course of action: sunk costs and project completion. The author proposes that sunk costs and need to complete exert simultaneous pressures, both independent and interactive, on a decision maker's level of commitment. The responses of 340 participants were analyzed and supported a complementary relationship between the 2 predictors. In addition, sunk costs demonstrated a curvilinear influence on commitment and an interaction with level of completion that supported a Level of Completion x Sunk Cost moderation model. (A marginal utility model was not supported.) Results are discussed in terms of their relevance toward offering a complementary view of 2 potential antecedents to a decision maker's propensity to escalate his or her commitment to a previously chosen course of action.

  17. Transaction costs of Tradable White Certificate schemes: The Energy Efficiency Commitment as case study

    2007-08-15

    This paper analyses the nature and scale of transaction costs (TCs) borne by obliged parties under a ''Tradable White Certificate'' (TWC) scheme. Taking the first phase of the Energy Efficiency Commitment (EEC1) in Great Britain as a case study, several sources of TCs were considered, such as search for information, persuasion of customers, negotiation with business partners, and measurement and verification activities. Information was obtained through interviews and a questionnaire distributed to obliged parties. Results show that the most significant sources of TCs were related to search for information, persuading customers and negotiating with managing agents/contractors to implement energy efficiency measures. Perceived high TCs related to contract negotiation and liability risks slightly reduced the low trading level. The scale of TCs was estimated to be around 10% and 30% of total investments costs for the lighting and insulation segments, respectively. The results indicate that, despite the presence and scale of TCs, the EEC1 scheme generated energy savings that yielded net societal benefits. Estimated financial benefits range from 0.6 to 6 p/kWh for insulation and lighting savings, respectively. When avoided external costs due to electricity savings are included, estimated economic benefits range from 3 to 8 p/kWh. Several lessons from the EEC1 can be drawn for TWC schemes. Among others, it is found that informative policy instruments to raise awareness among end-users are critical if a TWC scheme is to deliver cost-effective energy savings. In all, the nature and scale of TCs under TWC schemes will differ because of a number of endogenous and exogenous determinants. (author)

    The Voluntary Reporting Program for greenhouse gases is part of an attempt by the U.S. Government to develop innovative, low-cost, and nonregulatory approaches to limit emissions of greenhouse gases. It is one element in an array of such programs introduced in recent years as part of the effort being made by the United States to comply with its national commitment to stabilize emissions of greenhouse gases under the Framework Convention on Climate Change. The Voluntary Reporting Program, developed pursuant to Section 1605(b) of the Energy Policy Act of 1992, permits corporations, government agencies, households, and voluntary organizations to report to the Energy Information Administration (EIA) on actions taken that have reduced or avoided emissions of greenhouse gases.

    Full Text Available In this paper, the uncertainty of wind, solar and load; smart charging and discharging of plug-in hybrid electric vehicles (PHEVs to and from various energy sources; and the coordination of wind, solar power, PHEVs and cost-emission are considered in the smart grid unit commitment (UC. First, a multi-scenario simulation is used in which a set of valid scenarios is considered for the uncertainties of wind and solar energy sources and load. Then the UC problem for the set of scenarios is decomposed into the optimization of interactive agents by multi-agent technology. Agents’ action is represented by a genetic algorithm with adaptive crossover and mutation operators. The adaptive co-evolution of agents is reached by adaptive cooperative multipliers. Finally, simulation is implemented on an example of a power system containing thermal units, a wind farm, solar power plants and PHEVs. The results show the effectiveness of the proposed method. Thermal units, wind, solar power and PHEVs are mutually complementarily by the adaptive cooperative mechanism. The adaptive multipliers’ updating strategy can save more computational time and further improve the efficiency.

  1. Voluntary medical male circumcision: a qualitative study exploring the challenges of costing demand creation in eastern and southern Africa.

    Directory of Open Access Journals (Sweden)

    Jane T Bertrand

    Full Text Available BACKGROUND: This paper proposes an approach to estimating the costs of demand creation for voluntary medical male circumcision (VMMC scale-up in 13 countries of eastern and southern Africa. It addresses two key questions: (1 what are the elements of a standardized package for demand creation? And (2 what challenges exist and must be taken into account in estimating the costs of demand creation? METHODS AND FINDINGS: We conducted a key informant study on VMMC demand creation using purposive sampling to recruit seven people who provide technical assistance to government programs and manage budgets for VMMC demand creation. Key informants provided their views on the important elements of VMMC demand creation and the most effective funding allocations across different types of communication approaches (e.g., mass media, small media, outreach/mobilization. The key finding was the wide range of views, suggesting that a standard package of core demand creation elements would not be universally applicable. This underscored the importance of tailoring demand creation strategies and estimates to specific country contexts before estimating costs. The key informant interviews, supplemented by the researchers' field experience, identified these issues to be addressed in future costing exercises: variations in the cost of VMMC demand creation activities by country and program, decisions about the quality and comprehensiveness of programming, and lack of data on critical elements needed to "trigger the decision" among eligible men. CONCLUSIONS: Based on this study's findings, we propose a seven-step methodological approach to estimate the cost of VMMC scale-up in a priority country, based on our key assumptions. However, further work is needed to better understand core components of a demand creation package and how to cost them. Notwithstanding the methodological challenges, estimating the cost of demand creation remains an essential element in deriving

  2. Cost analysis of integrating the PrePex medical device into a voluntary medical male circumcision program in Zimbabwe.

    Emmanuel Njeuhmeli

    Full Text Available BACKGROUND: Fourteen African countries are scaling up voluntary medical male circumcision (VMMC for HIV prevention. Several devices that might offer alternatives to the three WHO-approved surgical VMMC procedures have been evaluated for use in adults. One such device is PrePex, which was prequalified by the WHO in May 2013. We utilized data from one of the PrePex field studies undertaken in Zimbabwe to identify cost considerations for introducing PrePex into the existing surgical circumcision program. METHODS AND FINDINGS: We evaluated the cost drivers and overall unit cost of VMMC at a site providing surgical VMMC as a routine service ("routine surgery site" and at a site that had added PrePex VMMC procedures to routine surgical VMMC as part of a research study ("mixed study site". We examined the main cost drivers and modeled hypothetical scenarios with varying ratios of surgical to PrePex circumcisions, different levels of site utilization, and a range of device prices. The unit costs per VMMC for the routine surgery and mixed study sites were $56 and $61, respectively. The two greatest contributors to unit price at both sites were consumables and staff. In the hypothetical scenarios, the unit cost increased as site utilization decreased, as the ratio of PrePex to surgical VMMC increased, and as device price increased. CONCLUSIONS: VMMC unit costs for routine surgery and mixed study sites were similar. Low service utilization was projected to result in the greatest increases in unit price. Countries that wish to incorporate PrePex into their circumcision programs should plan to maximize staff utilization and ensure that sites function at maximum capacity to achieve the lowest unit cost. Further costing studies will be necessary once routine implementation of PrePex-based circumcision is established.

  3. A social cost-benefit criterion for evaluating Voluntary Counseling and Testing with an application to Tanzania.

    2010-02-01

    There are many interventions for HIV/AIDS that require that people know their status and hence require a HIV test. Testing that is driven by a desire to prevent the spread of the disease often has an indirect effect on others. These external effects need to be identified, quantified and included as part of the benefits and costs of testing. Pioneering analyses of HIV testing by Philipson and Posner have introduced the economic calculus of individual expected benefits and costs of activities into an understanding of the HIV epidemic. What is required for social evaluations is an extension of the analysis to ensure that external effects are included. The objective of this paper is two-fold. First we seek to formulate cost-benefit criteria that incorporate fully the external effects in the evaluation of Voluntary Counseling and Testing (VCT). We achieve this by recasting the individual calculus of benefits and costs to a couple setting. We can then compare an individual's cost-benefit analysis of being tested with social criteria that look at outcomes from a couple's perspective for both separate and dual/joint testing. Second we aim to apply our social criteria to VCT programs as they currently operate in Tanzania and how these programs might operate in the future when they are scaled up to relate to the general population. We develop social criteria for evaluating separate and dual VCT using a couple's perspective with and without altruism. Therefore, the welfare function is based on two individual expected utility functions viewed as a couple, either married or regular partners. The benefits are the averted lives lost whenever discordant couples are revealed. The costs of VCT are the benefits of unprotected sex that the couple foregoes and the costs of the testing and counseling. The cost-benefit criteria are applied to VCT programs in Tanzania. The four main ingredients estimated are: the foregone benefit of unprotected sex (measured by the compensated wage

    to evaluate the costs-effectiveness of scaling up community-based VCT in West-Java. the Asian epidemic model (AEM) and resource needs model (RNM) were used to calculate incremental costs per HIV infection averted and per disability-adjusted life years saved (DALYs). Locally monitored demographic, epidemiological behavior and cost data were used as model input. scaling up community-based VCT in West-Java will reduce the overall population prevalence by 36% in 2030 and costs US$248 per HIV infection averted and US$9.17 per DALY saved. Cost-effectiveness estimation were most sensitive to the impact of VCT on condom use and to the population size of clients of female sex workers (FSWs), but were overall robust. The total costs for scaling up community-based VCT range between US$1.3 and 3.8 million per year and require the number of VCT integrated clinics at public community health centers to increase from 73 in 2010 to 594 in 2030. scaling up community-based VCT seems both an effective and cost-effective intervention. However, in order to prioritize VCT in HIV/AIDS control in West-Java, issues of budget availability and organizational capacity should be addressed.

    People frequently escalate their commitment to failing endeavors. Explanations for such behavior typically involve loss aversion, failure to recognize other alternatives, and concerns with justifying prior actions; all of these factors produce recommitment to previous decisions with the goal of erasing losses and vindicating these decisions. Solutions to escalation of commitment have therefore focused on external oversight and divided responsibility during decision making to attenuate loss aversion, blindness to alternatives, and justification biases. However, these solutions require substantial resources and have additional adverse effects. The present studies tested an alternative method for de-escalating commitment: activating broad motivations for growth and advancement (promotion). This approach should reduce concerns with loss and increase perceptions of alternatives, thereby attenuating justification motives. In two studies featuring hypothetical financial decisions, activating promotion motivations reduced recommitment to poorly performing investments as compared with both not activating any additional motivations and activating motivations for safety and security (prevention).

    Does tuning to one's native language explain the “sensitive period” for language learning? We explore the idea that tuning to (or becoming more selective for) the properties of one's native-language could result in being less open (or plastic) for tuning to the properties of a new language. To explore how this might lead to the sensitive period for grammar learning, we ask if tuning to an earlier-learned aspect of language (sound structure) has an impact on the neural representation of a later-learned aspect (grammar). English-speaking adults learned one of two miniature artificial languages (MALs) over 4 days in the lab. Compared to English, both languages had novel grammar, but only one was comprised of novel sounds. After learning a language, participants were scanned while judging the grammaticality of sentences. Judgments were performed for the newly learned language and English. Learners of the similar-sounds language recruited regions that overlapped more with English. Learners of the distinct-sounds language, however, recruited the Superior Temporal Gyrus (STG) to a greater extent, which was coactive with the Inferior Frontal Gyrus (IFG). Across learners, recruitment of IFG (but not STG) predicted both learning success in tests conducted prior to the scan and grammatical judgment ability during the scan. Data suggest that adults' difficulty learning language, especially grammar, could be due, at least in part, to the neural commitments they have made to the lower level linguistic components of their native language.

In a context of scarce resources, doctors are required to take opportunity cost into account when prescribing treatments, while cost containment policies cannot overlook their active role in determining health care resource allocation. This paper addresses this issue, investigating the effects of cost containment measures in the market of biosimilar drugs that represent a viable and cost-saving strategy for the reduction of health care expenditure. The analysis focuses on a particular region in Italy, where several timely policies to incentivize biosimilar prescribing were launched. Methods: Drugs were identified by the anatomical therapeutic chemical classification system. Information about biosimilar drugs and their originator biological products was extracted from the IMS Health regional database. Drug consumption was expressed in terms of counting units, while expenditure was evaluated in Euro (€.The market penetration of biosimilars was analyzed by year and quarterly. Results: In the Campania region of Italy, the effects of cost containment policies, launched between 2009 and 2013, showed the prescription of biosimilars strongly increasing in 2010 until prescribing levels reached and exceeded the market share of the reference biological products in 2012. After a slight reduction, a plateau was observed at the beginning of 2013. At the same time, the use of the originator products had been decreasing until the first quarter of 2011. However, after a 1-year plateau, this trend

  13. How much does it cost to improve access to voluntary medical male circumcision among high-risk, low-income communities in Uganda?

    Full Text Available The Ugandan Ministry of Health has endorsed voluntary medical male circumcision as an HIV prevention strategy and has set ambitious goals (e.g., 4.2 million circumcisions by 2015. Innovative strategies to improve access for hard to reach, high risk, and poor populations are essential for reaching such goals. In 2009, the Makerere University Walter Reed Project began the first facility-based VMMC program in Uganda in a non-research setting. In addition, a mobile clinic began providing VMMC services to more remote, rural locations in 2011. The primary objective of this study was to estimate the average cost of performing VMMCs in the mobile clinic compared to those performed in health facilities (fixed sites. The difference between such costs is the cost of improving access to VMMC.A micro-costing approach was used to estimate costs from the service provider's perspective of a circumcision. Supply chain and higher-level program support costs are not included.The average cost (US$2012 of resources used per circumcision was $61 in the mobile program ($72 for more remote locations compared to $34 at the fixed site. Costs for community mobilization, HIV testing, the initial medical exam, and staff for performing VMMC operations were similar for both programs. The cost of disposable surgical kits, the additional upfront cost for the mobile clinic, and additional costs for staff drive the differences in costs between the two programs. Cost estimates are relatively insensitive to patient flow over time.The MUWRP VMMC program improves access for hard to reach, relatively poor, and high-risk rural populations for a cost of $27-$38 per VMMC. Costs to patients to access services are almost certainly less in the mobile program, by reducing out-of-pocket travel expenses and lost time and associated income, all of which have been shown to be barriers for accessing treatment.

    To date, few studies have compared Acceptance and Commitment Therapy (ACT) for longstanding pain with established treatments. Only 1 study has evaluated the cost-effectiveness of ACT. The aim of the current study was to evaluate the efficacy and cost-effectiveness of ACT and applied relaxation (AR) for adults with unspecific, longstanding pain. On the basis of the inclusion criteria 60 consecutive patients received 12 weekly group sessions of ACT or AR. Data were collected pretreatment, midtreatment, and posttreatment, as well as at 3- and 6-month follow-up. Growth curve modeling was used to analyze treatment effects on pain disability, pain intensity, health-related quality of life (physical domain), anxiety, depression, and acceptance. Significant improvements were seen across conditions (pretreatment to follow-up assessment) on all outcome measures. Pain disability decreased significantly in ACT relative to AR from preassessment to postassessment. A corresponding decrease in pain disability was seen in AR between postassessment and 6-month follow-up. Pain acceptance increased only in ACT, and this effect was maintained at 6-month follow-up. Approximately 20% of the participants achieved clinically significant change after treatment. Health economic analyses showed that ACT was more cost-effective than AR at post and 3-month follow-up assessment, but not at 6-month follow-up. More studies investigating moderators and mediators of change are needed. The present study is one of few that have evaluated the cost-effectiveness of ACT and AR and compared ACT with an established behavioral intervention, and the results provide additional support for behavioral interventions for longstanding pain.

    The Roux-en-Y gastric bypass is the gold standard procedure for weight loss. This relatively complex procedure has excellent outcomes when performed via laparoscopy. The advent of the DaVinci robotic platform has been a technological advancement. Our goal is to provide information regarding the cost, time commitment, and advantages of transitioning an LRYGB program to an RRYGB program in an academic setting. We retrospectively reviewed the last 25 laparoscopic gastric bypass procedures and the first 25 robotic gastric bypass procedures performed by a single surgeon. We compared clinical outcomes and focused on time and hospital cost during this transition phase. There was no significant demographic difference between the groups. The mean age was 41.7 (RRYGB) years vs 43.4 (LRYGM) years. The mean BMI were similar between groups, 45.3 vs 46.5 kg/m(2) for RRYGB and LRYGB. No anastomotic leaks or mortalities were noted. There was one anastomotic stricture in both groups. Excess weight loss was similar in both groups at 1 year. There was a significant increase in operative time with RRYGB, mean 241 min vs mean 174 min (p = 0.0005). Operative time fell by 25 min after the first 10 cases. The hospital cost was also increased with RRYGB mean $5922 vs $4395 (p = 0.03). Transitioning from a laparoscopic to a robotic practice can be done safely, however, the initial operative times were longer and the hospital cost was higher for robotic gastric bypass. We hope in the future that these will decrease after overcoming the learning and as the technology becomes widespread.

    Voluntary medical male circumcision is an integral part of the South African government's response to the HIV and AIDS epidemic. However, there remains a limited body of economic analysis on the cost of VMMC programming, and the demand creation activities used to mobilize males, especially among adolescent boys in school. This study addresses this gap by presenting the costs of a VMMC program which adopted two demand creation strategies targeting school-going males in South Africa. Cost data was collected from a VMMC program in the KwaZulu-Natal province of South Africa. A retrospective, micro-costing ingredient approach was applied to identify, measure and value resources of two demand creation strategies targeting young males. The program circumcised 4987 young males between May 2011 and February 2013, at a cost of $127.68 per circumcision. Demand creation activities accounted for 32% of the total cost, HCT contributing 10% with the medical circumcision procedure accounting for 58% of the total cost. Using the first demand creation strategy, 2168 circumcisions were performed at a cost of $149.57 per circumcision. Following this first strategy, a second demand creation strategy was adopted which saw the cost fall to $110.85 per circumcision. More young males were recruited following the second strategy with clinic services more efficiently utilized. Whilst the cost per circumcision of demand activities rose slightly between the first ($39.94) and second ($41.65) strategy, there was a substantial reduction in the cost of the circumcision procedure; $90.01 under the first strategy falling to $60.60 following the adoption of the second demand creation strategy. Ensuring the optimal use of clinic facilities was the primary driver in reducing the cost per circumcision. This VMMC program has illustrated the value of evaluating progress and instituting changes to attain better cost efficiencies. This adjustment resulted in a substantial reduction in the cost per

    Section 131(c) of the Energy Policy Act of 1992 (EPACT) (Public Law 102-486) requires the Department of Energy (DOE) to evaluate the costs and benefits of federally mandated energy efficiency reporting requirements and voluntary energy efficiency improvement targets for energy-intensive industries. It also requires DOE to evaluate the role of reporting and targets in improving energy efficiency. Specifically, the legislation states: Not later than one year after the data of the enactment of this Act, the Secretary shall, in consultation with affected industries, evaluate and report to the Congress regarding the establishment of Federally mandated energy efficiency reporting requirements and voluntary energy efficiency improvement targets for energy intensive industries. Such report shall include an evaluation of the costs and benefits of such reporting requirements and voluntary energy efficiency improvement targets, and recommendations regarding the role of such activities in improving energy efficiency in energy intensive industries. This report is DOE`s response to that directive. It is the culmination of a year-long study that included (1) analysis of documents pertaining to a previous reporting and targets effort, the industrial Energy Efficiency Improvements Program (or the CE-189 program, following the designation of the reporting form used to collect data in that program), administered by DOE from 1976 to 1985, as well as other important background information; (2) extensive consultations with government and industry officials regarding the CE-189 Program, experience with other programs that have reporting elements, and the attributes of possible alternative strategies for reporting and targets; and (3) analyses of the costs and benefits of the CE-189 Program and several alternatives to the CE-189 approach.

    Voluntary emergency and relief services, such as fire brigades or rescue organisations, form the backbone of disaster management in most of European countries. In Austria, disaster management relies on the cooperation between governmental and non-governmental institutions: When a disaster occurs, the volunteer organizations act as auxiliaries to the responsible disaster management authority. The assessment of costs and benefits of these emergency services is a crucial component of risk and disaster management strategies, since public means are getting scarcer and these costs can reach critical levels for low-income municipalities. As extreme events and emergency operations are likely to increase due to climate change, the efficient allocation of public budgets for risk and disaster management becomes more important. Hence, both, the costs and the benefits must be known, but voluntary and professional work is hardly documented and assessed comprehensively. Whereas the costs of emergency services can be calculated using market values and an analysis of public and institutional budgets, the benefits of voluntary efforts cannot be assessed easily. We present empirical data on costs of voluntary and professional emergency services during the floods of 2002, 2005 and 2013 in Austria and Germany on different scales, obtained from public authorities, fire brigades and by means of public surveys. From these results, we derive a calculation framework and data requirements for assessing costs of emergency services. To consider the different stakeholders needs of administration, emergency institutions and voluntary members, we carried out workshops, first to identify future challenges in voluntary work for disaster management instigated by climate change and second, to develop approaches how the voluntary system can be uphold when facing increasing adverse impacts of natural hazards. The empirical results as well as the workshop outcome shall be translated into policy

    Full Text Available BACKGROUND: There is strong evidence showing that voluntary medical male circumcision (VMMC reduces HIV incidence in men. To inform the VMMC policies and goals of 13 priority countries in eastern and southern Africa, we estimate the impact and cost of scaling up adult VMMC using updated, country-specific data. METHODS AND FINDINGS: We use the Decision Makers' Program Planning Tool (DMPPT to model the impact and cost of scaling up adult VMMC in Botswana, Lesotho, Malawi, Mozambique, Namibia, Rwanda, South Africa, Swaziland, Tanzania, Uganda, Zambia, Zimbabwe, and Nyanza Province in Kenya. We use epidemiologic and demographic data from recent household surveys for each country. The cost of VMMC ranges from US$65.85 to US$95.15 per VMMC performed, based on a cost assessment of VMMC services aligned with the World Health Organization's considerations of models for optimizing volume and efficiencies. Results from the DMPPT models suggest that scaling up adult VMMC to reach 80% coverage in the 13 countries by 2015 would entail performing 20.34 million circumcisions between 2011 and 2015 and an additional 8.42 million between 2016 and 2025 (to maintain the 80% coverage. Such a scale-up would result in averting 3.36 million new HIV infections through 2025. In addition, while the model shows that this scale-up would cost a total of US$2 billion between 2011 and 2025, it would result in net savings (due to averted treatment and care costs amounting to US$16.51 billion. CONCLUSIONS: This study suggests that rapid scale-up of VMMC in eastern and southern Africa is warranted based on the likely impact on the region's HIV epidemics and net savings. Scaling up of safe VMMC in eastern and southern Africa will lead to a substantial reduction in HIV infections in the countries and lower health system costs through averted HIV care costs.

    Full Text Available In 2007, the World Health Organization (WHO recommended scaling up voluntary medical male circumcision (VMMC in priority countries with high HIV prevalence and low male circumcision (MC prevalence. According to the Joint United Nations Programme on HIV/AIDS (UNAIDS, an estimated 5.8 million males had undergone VMMC by the end of 2013. Implementation experience has raised questions about the need to refocus VMMC programs on specific subpopulations for the greatest epidemiological impact and programmatic effectiveness. As Malawi prepared its national operational plan for VMMC, it sought to examine the impacts of focusing on specific subpopulations by age and region.We used the Decision Makers' Program Planning Toolkit, Version 2.0, to study the impact of scaling up VMMC to different target populations of Malawi. National MC prevalence by age group from the 2010 Demographic and Health Survey was scaled according to the MC prevalence for each district and then halved, to adjust for over-reporting of circumcision. In-country stakeholders advised a VMMC unit cost of $100, based on implementation experience. We derived a cost of $451 per patient-year for antiretroviral therapy from costs collected as part of a strategic planning exercise previously conducted in- country by UNAIDS.Over a fifteen-year period, circumcising males ages 10-29 would avert 75% of HIV infections, and circumcising males ages 10-34 would avert 88% of infections, compared to the current strategy of circumcising males ages 15-49. The Ministry of Health's South West and South East health zones had the lowest cost per HIV infection averted. Moreover, VMMC met WHO's definition of cost-effectiveness (that is, the cost per disability-adjusted life-year [DALY] saved was less than three times the per capita gross domestic product in all health zones except Central East.

    Voluntary medical male circumcision (VMMC) has been shown to be an effective prevention strategy against HIV infection in males [1–3]. Since 2007, the President’s Emergency Plan for AIDS Relief (PEPFAR) has supported VMMC programs in 14 priority countries in Africa. Today several of these countries are preparing to transition their VMMC programs from a scale-up and expansion phase to a maintenance phase. As they do so, they must consider the best approaches to sustain high levels of male circumcision in the population. The two alternatives under consideration are circumcising adolescents 10–14 years old over the long term or integrating early infant male circumcision (EIMC) into maternal and child health programs. The paper presents an analysis, using the Decision Makers Program Planning Tool, Version 2.0 (DMPPT 2.0), of the estimated cost and impact of introducing EIMC into existing VMMC programs in several countries in eastern and southern Africa. Limited cost data exist for the implementation of EIMC, but preliminary studies, such as the one detailed in Mangenah, et al. [4–5], suggest that the cost of EIMC may be less than that of adolescent and adult male circumcision. If this is the case, then adding EIMC to the VMMC program will increase the number of circumcisions that need to be performed but will not increase the total cost of the program over the long term. In addition, we found that a delayed or slow start-up of EIMC would not substantially reduce the impact of adding it to the program or increase cumulative long-term costs, which should make introduction of EIMC more feasible and attractive to countries contemplating such a program innovation.

    Conscientious commitment, the reverse of conscientious objection, inspires healthcare providers to overcome barriers to delivery of reproductive services to protect and advance women's health. History shows social reformers experiencing religious condemnation and imprisonment for promoting means of birth control, until access became popularly accepted. Voluntary sterilization generally followed this pattern to acceptance, but overcoming resistance to voluntary abortion calls for courage and remains challenging. The challenge is aggravated by religious doctrines that view treatment of ectopic pregnancy, spontaneous abortion, and emergency contraception not by reference to women's healthcare needs, but through the lens of abortion. However, modern legal systems increasingly reject this myopic approach. Providers' conscientious commitment is to deliver treatments directed to women's healthcare needs, giving priority to patient care over adherence to conservative religious doctrines or religious self-interest. The development of in vitro fertilization to address childlessness further illustrates the inspiration of conscientious commitment over conservative objections.

    Full Text Available Empirical studies and population-level policy simulations show the importance of voluntary medical male circumcision (VMMC in generalized epidemics. This paper complements available scenario-based studies (projecting costs and outcomes over some policy period, typically spanning decades by adopting an incremental approach-analyzing the expected consequences of circumcising one male individual with specific characteristics in a specific year. This approach yields more precise estimates of VMMC's cost-effectiveness and identifies the outcomes of current investments in VMMC (e.g., within a fiscal budget period rather than of investments spread over the entire policy period.The model has three components. We adapted the ASSA2008 model, a demographic and epidemiological model of the HIV epidemic in South Africa, to analyze the impact of one VMMC on HIV incidence over time and across the population. A costing module tracked the costs of VMMC and the resulting financial savings owing to reduced HIV incidence over time. Then, we used several financial indicators to assess the cost-effectiveness of and financial return on investments in VMMC. One circumcision of a young man up to age 20 prevents on average over 0.2 HIV infections, but this effect declines steeply with age, e.g., to 0.08 by age 30. Net financial savings from one VMMC at age 20 are estimated at US$617 at a discount rate of 5% and are lower for circumcisions both at younger ages (because the savings occur later and are discounted more and at older ages (because male circumcision becomes less effective. Investments in male circumcision carry a financial rate of return of up to 14.5% (for circumcisions at age 20. The cost of a male circumcision is refinanced fastest, after 13 y, for circumcisions at ages 20 to 25. Principal limitations of the analysis arise from the long time (decades over which the effects of VMMC unfold-the results are therefore sensitive to the discount rate applied, and

  8. Commitment Cost and Contractual Coordination Mechanism of Supply Chain under OEM%承诺成本与OEM下的供应链契约协调机制

    we can basically alter the equilibrium of coordination model of supply chain when considering commitment cost. If the cost is high enough, the unilateral payment is only a non-strict dominant strategy under either certain or uncertain commitment; when the imperfect information and all exogenous constraints leading to unilateral payment are excluded,incompatible commitment will cause conflicts. Taking supply chain with complementary suppliers for example, each supplier can improve his performance by offering a return policy to the assembler while the best contract depends on that offered by the other supplier. Moreover, the suppliers still have the rights to negotiate with each other to share their profits properly.There is a unique and stable equilibrium in which the optimal contract happens to fully coordinate the whole chain. Finally a numerical example has verified this conclusion.%考虑契约承诺成本就能改变供应链协调模型的均衡.假如承诺成本足够高,确定性和非确定性承诺策略都使得单边支付成为唯一稳定的非产格占优均衡;当排除了不完全信息和导致单边支付的外在约束之后,非相容性承诺则是分歧产生的原因.以OEM下由互补性供应商单组装商组成的典型供应链为例,得到了基于供应商之间最优反应的回购契约并允许加上再协商的契约协调机制可极大改善成员福利并达成唯一稳定均衡的结论,并用数值算例予以了印证.

  10. Voluntary euthanasia: a utilitarian perspective.

    Science.gov (United States)

    2003-10-01

    Belgium legalised voluntary euthanasia in 2002, thus ending the long isolation of the Netherlands as the only country in which doctors could openly give lethal injections to patients who have requested help in dying. Meanwhile in Oregon, in the United States, doctors may prescribe drugs for terminally ill patients, who can use them to end their life--if they are able to swallow and digest them. But despite President Bush's oft-repeated statements that his philosophy is to 'trust individuals to make the right decisions' and his opposition to 'distant bureaucracies', his administration is doing its best to prevent Oregonians acting in accordance with a law that its voters have twice ratified. The situation regarding voluntary euthanasia around the world is therefore very much in flux. This essay reviews ethical arguments regarding voluntary euthanasia and physician-assisted suicide from a utilitarian perspective. I shall begin by asking why it is normally wrong to kill an innocent person, and whether these reasons apply to aiding a person who, when rational and competent, asks to be killed or given the means to commit suicide. Then I shall consider more specific utilitarian arguments for and against permitting voluntary euthanasia.

    1976-10-01

    A cost/benefit study was made to determine the cost and effectiveness of radioactive waste (radwaste) treatment systems for decreasing the release of radioactive materials from a model nuclear fuel reprocessing plant which processes light-water reactor (LWR) fuels, and to determine the radiological impact (dose commitment) of the released materials on the environment. The study is designed to assist in defining the term as low as reasonably achievable in relation to limiting the release of radioactive materials from nuclear facilities. The base case model plant is representative of current plant technology and has an annual capacity of 1500 metric tons of LWR fuel. Additional radwaste treatment systems are added to the base case plant in a series of case studies to decrease the amounts of radioactive materials released and to reduce the radiological dose commitment to the population in the surrounding area. The cost for the added waste treatment operations and the corresponding dose commitments are calculated for each case. In the final analysis, radiological dose is plotted vs the annual cost for treatment of the radwastes. The status of the radwaste treatment methods used in the case studies is discussed. Much of the technology used in the advanced cases is in an early stage of development and is not suitable for immediate use. The methodology used in estimating the costs, and the radiological doses, detailed calculations, and tabulations are presented in Appendix A and ORNL-4992. This report is a revision of the original study (ORNL/TM-4901).

  16. Evaluating the cost of adult voluntary medical male circumcision in a mixed (surgical and PrePex site compared to a hypothetical PrePex-only site in South Africa

    Directory of Open Access Journals (Sweden)

    Hae-Young Kim

    2015-12-01

    Full Text Available Background: Several circumcision devices have been evaluated for a safe and simplified male circumcision among adults. The PrePex device was prequalified for voluntary male medical circumcision (VMMC in May 2013 by the World Health Organization and is expected to simplify the procedure safely while reducing cost. South Africa is scaling up VMMC. Objective: To evaluate the overall unit cost of VMMC at a mixed site vs. a hypothetical PrePex-only site in South Africa. Design: We evaluated the overall unit cost of VMMC at a mixed site where PrePex VMMC procedure was added to routine forceps-guided scalpel-based VMMC in Soweto, South Africa. We abstracted costs and then modeled these costs for a hypothetical PrePex-only site, at which 9,600 PrePex circumcisions per year could be done. We examined cost drivers and modeled costs, varying the price of the PrePex device. The healthcare system perspective was used. Results: In both sites, the main contributors of cost were personnel and consumables. If 10% of all VMMC were by PrePex at the mixed site, the overall costs of the surgical method and PrePex were similar – US$59.62 and $59.53, respectively. At the hypothetical PrePex-only site, the unit cost was US$51.10 with PrePex circumcisions having markedly lower personnel and biohazardous waste management costs. In sensitivity analysis with the cost of PrePex kit reduced to US$10 and $2, the cost of VMMC was further reduced. Conclusions: Adding PrePex to an existing site did not necessarily reduce the overall costs of VMMC. However, starting a new PrePex-only site is feasible and may significantly reduce the overall cost by lowering both personnel and capital costs, thus being cost-effective in the long term. Achieving a lower cost for PrePex will be an important contributor to the scale-up of VMMC.

  17. Cost-Utility of Group Acceptance and Commitment Therapy for Fibromyalgia Versus Recommended Drugs: An Economic Analysis Alongside a 6-Month Randomized Controlled Trial Conducted in Spain (EFFIGACT Study).

    2017-07-01

    The aim of this study was to analyze the cost utility of a group-based form of acceptance and commitment therapy (GACT) in patients with fibromyalgia (FM) compared with patients receiving recommended pharmacological treatment (RPT) or on a waiting list (WL). The data were derived from a previously published study, a randomized controlled trial that focused on clinical outcomes. Health economic outcomes included health-related quality of life and health care use at baseline and at 6-month follow-up using the EuroQoL and the Client Service Receipt Inventory, respectively. Analyses included quality-adjusted life years, direct and indirect cost differences, and incremental cost effectiveness ratios. A total of 156 FM patients were randomized (51 GACT, 52 RPT, 53 WL). GACT was related to significantly less direct costs over the 6-month study period compared with both control arms (GACT €824.2 ± 1,062.7 vs RPT €1,730.7 ± 1,656.8 vs WL €2,462.7 ± 2,822.0). Lower direct costs for GACT compared with RPT were due to lower costs from primary care visits and FM-related medications. The incremental cost effectiveness ratios were dominant in the completers' analysis and remained robust in the sensitivity analyses. In conclusion, acceptance and commitment therapy appears to be a cost-effective treatment compared with RPT in patients with FM. Decision-makers have to prioritize their budget on the treatment option that is the most cost effective for the management of a specific patient group. From government as well as health care perspectives, this study shows that a GACT is more cost effective than pharmacological treatment in management of FM. Copyright © 2017 American Pain Society.

    Stoyles, Byron J; Costreie, Sorin

    2013-12-01

    Our goal in this article is to explicate the way, and the extent to which, euthanasia can be voluntary from both the perspective of the patient and the perspective of the health care providers involved in the patient's care. More significantly, we aim to challenge the way in which those engaged in ongoing philosophical debates regarding the morality of euthanasia draw distinctions between voluntary, involuntary, and nonvoluntary euthanasia on the grounds that drawing the distinctions in the traditional manner (1) fails to reflect what is important from the patient's perspective and (2) fails to reflect the significance of health care providers' interests, including their autonomy and integrity.

  2. Perceived medical benefit, peer/partner influence and safety and cost to access the service: client motivators for voluntary seeking of medical male circumcision in Iganga district eastern Uganda, a qualitative study.

    Muhamadi, Lubega; Ibrahim, Musenze; Wabwire-Mangen, Fred; Peterson, Stefan; Reynolds, Steven J

    2013-01-01

    Although voluntary medical male circumcision (VMMC) in Iganga district was launched in 2010 as part of the Uganda national strategy to prevent new HIV infections with a target of having 129,896 eligible males circumcised by 2012, only 35,000 (27%) of the anticipated target had been circumcised by mid 2012. There was paucity of information on why uptake of VMMC was low in this setting where HIV awareness is presumably high. This study sought to understand motivators for uptake of VMMC from the perspective of the clients themselves in order to advocate for feasible approaches to expanding uptake of VMMC in Iganga district and similar settings. In Iganga district, we conducted seven key informant interviews with staff who work in the VMMC clinics and twenty in-depth interviews with clients who had accepted and undergone VMMC. Ten focus-group discussions including a total of 112 participants were also conducted with clients who had undergone VMMC. Motivators for uptake of VMMC in the perspective of the circumcised clients and the health care staff included: perceived medical benefit to those circumcised such as protection against acquiring HIV and other sexually transmitted diseases, peer/partner influence, sexual satisfaction and safety and cost to access the service. Since perceived medical benefit was a motivator for seeking VMMC, it can be used to strengthen campaigns for increasing uptake of VMMC. Peer influence could also be used in advocacy campaigns for VMMC expansion, especially using peers who have already undergone VMMC. There is need to ensure that safety and cost to access the service is affordable especially to rural poor as it was mentioned as a motivator for seeking VMMC.

  4. Economic grand rounds: Can states implement involuntary outpatient commitment within existing state budgets?

    Swartz, Marvin S; Swanson, Jeffrey W

    2013-01-01

    Many states have not implemented involuntary outpatient commitment, possibly believing that the program is too costly. A review of New York State's experience found that even though the state had appropriated funds for implementing outpatient commitment, overall cost savings were realized. This column presents an analysis in which net costs of outpatient commitment were calculated by using data from a randomized controlled study in North Carolina, where court-ordered treatment was implemented without additional appropriations. The analysis found that outpatient commitment in North Carolina was relatively cost-neutral when relevant costs for persons on outpatient commitment were compared with costs for persons not on outpatient commitment, regardless of commitment duration. Outpatient commitment of six months or more, combined with provision of outpatient services, appeared to result in cost savings of 40%. Findings suggest that states with adequate services to provide consumers on outpatient commitment may implement a program without new funding.

  8. Formalizing the Relationship Between Commitment and Basic Cryptographic Primitives

    2016-11-01

    Full Text Available Signcryption is a cryptographic primitive which offers the functionality of both digital signature and encryption with lower combined computational cost. On the other hand, commitment scheme allows an entity to commit to a value, where the entity reveals the committed value later during a decommit phase. In this paper, we explore the connection between commitment schemes, public key encryption, digital signatures and signcryption. We establish formal relationship between commitment and the other primitives. Our main result is that we show signcryption can be used as a commitment scheme with appropriate security notions. We show that if the underlying signcryption scheme is IND-CCA2 secure, then the hiding property of the commitment scheme is satisfied. Similarly, we show that if the underlying signcryption scheme is unforgeable, then the relaxed biding property of the commitment scheme is satisfied. Moreover, we prove that if the underlying signcryption scheme is NM-CCA2, then the commitment scheme is non-malleable.

  9. A Fuzzy Commitment Scheme

    Al-saggaf, Alawi A

    2008-01-01

    This paper attempt has been made to explain a fuzzy commitment scheme. In the conventional Commitment schemes, both committed string m and valid opening key are required to enable the sender to prove the commitment. However there could be many instances where the transmission involves noise or minor errors arising purely because of the factors over which neither the sender nor the receiver have any control. The fuzzy commitment scheme presented in this paper is to accept the opening key that is close to the original one in suitable distance metric, but not necessarily identical. The concept itself is illustrated with the help of simple situation.

  10. Organizational Commitment in Nurses

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Introduction: As increase in nursing shortages, absenteeism and turn over, organizational commitment is extensively important for retention of nurses. Organizational committed staff has higher efficiency; thus, more tendency to stay and less absenteeism are their characteristics. Being aware of nursing staff’s organizational commitment provides adequate information to authorities to make- decision and lead in adopting proper methods to determine the effectiveness of the Health Centers in the country. Hence, the present study carried out to examine the amount of nurses’ organizational commitment. Materials and Methods: The nurses were 200 subjects who participated in this descriptive- analytical study. They were engaged in teaching hospitals in Zahedan in 2016. Data were collected from 200 nurses in major hospitals. Samples were selected by a random sampling method. Questionnaires, including Demographic data, Organizational Commitment Questionnaires. Data were analyzed by SPSS version 21.0 using descriptive statistics, Pearson correlation, variance analysis and t-test. Findings: The results showed nurses’ average age was 30.05±6.56. The female subjects were 162. The average level of organizational commitment among nurses was 74.24±8.36, emotional commitment was 25.58±3.26. The component, and continued commitment was 24.36±4.05 and 24.30±3.48 for normative commitment. There was no relationship between the age and organizational commitment, emotional and continuing commitment, but their relation was significant with normative commitment. Conclusion: The result of the present study indicated that the grade of the organizational commitment of participating nurses in was moderate, in this study. An organization requires to the staff foe gaining to its goals, who do their duty along love and enthusiasm and are committed to this organization. Proper ground should be established in order to make and maintain these features in the staff.

  13. Managing by commitments.

    Sull, Donald N

    2003-06-01

    What makes a great manager great? Despite differences in their personal attributes, successful managers all excel in the making, honoring, and remaking of commitments. Managerial commitments take many forms, from capital investments to personnel decisions to public statements, but each exerts both immediate and enduring influence on a company. A leader's commitments shape a business's identity, define its strengths and weaknesses, establish its opportunities and limitations, and set its direction. Executives can all too easily forget that commitments are extraordinarily powerful. Caught up in the present, managers often take actions that, while beneficial in the near term, impose lasting constraints on their operations and organizations. When market or competitive conditions change, they can find themselves unable to respond effectively. Managers who understand the nature and power of their commitments can wield them more effectively throughout a company's life cycle. Entrepreneurs can avoid taking actions that imprint a new venture with a dysfunctional character. Managers in established enterprises can buttress past commitments that retain their currency and learn to recognize when commitments have become roadblocks to needed changes. The manager can then replace those roadblocks with new, rejuvenating commitments. That doesn't mean you should try to anticipate all the long-run consequences of every commitment--and it certainly doesn't mean you should shy away from making commitments. But it does mean that before making important decisions about, say, operating processes or partnerships, you should always ask yourself: Is this a process or relationship that we can live with in the future? Am I locking us into a course that we'll come to regret?

    Scarr, S

    2000-06-01

    David Lykken's proposal to license married parents for child rearing, and to deny the same opportunity to single and inept parents, springs from his deep concern for millions of youngsters cruelly subjected to abusive and neglectful rearing circumstances. Children from such inadequate homes grow up to have high rates of school failure, criminality, and drug addiction. The problem is clear, but Lykken's remedies of mandated marriage and parental licensure are unacceptable in U.S. society, where our reproductive rights are fortunately protected by our Constitution. As a devoted proponent of reproductive rights, I propose a legally and morally acceptable proposal to the same end. Increasing women's effective control of reproduction and moving toward entirely voluntary parenthood will accomplish the same goals without compromising our civil liberties.

  17. Functional Flexibility in Women's Commitment-Skepticism Bias

    Directory of Open Access Journals (Sweden)

    Christina M. Brown

    2015-04-01

    Full Text Available If a woman overestimates her romantic partner's commitment, the cost to her fitness—reproduction without an investing partner—can be considerable. Error Management Theory predicts that women have an evolved bias to be skeptical of men's commitment in a relationship, which reduces the likelihood of making a costly false positive error. However, because error probabilities are inversely related, this commitment-skepticism bias simultaneously increases the likelihood of missed opportunities, or false negatives. False positives when gauging a partner's commitment are the more costly error for women, but missing an opportunity to secure a genuinely high-quality mate can also be quite costly. We predicted and found that women's mating cognitions are functionally flexible, such that women do not exhibit the commitment-skepticism bias when faced with behavioral evidence that a male partner is willing to commit (Study 1. This suggests that relationship-enhancing behaviors are one contextual cue that may lessen the bias. However, not all relationship-enhancing behaviors are equally diagnostic of a person's true commitment intent. When comparing men and women's commitment thresholds, we found that women require more behavioral evidence than men do to feel certain of their partner's commitment to them (Study 2.

    Voluntary medical incident reports lacking consistency and accuracy impede the ultimate use of the reports for patient safety research. To improve this, two coders examined harm score usage in a voluntary medical incident reporting system where the harm scores were selected from a predefined list by different reporters. The two coders inter-rater agreement percent was 82%. The major categories and reviewed harm score jointly demonstrate that this process is critical and necessary in preparing the voluntary reports for further content and semantics analysis.

    Full Text Available In order to attract more promising young people to join the military and enhance combat capability, Taiwan’s Department of Defense is transforming the nation’s military service system from a draft system, which has been in effect for more than sixty years, to an all-volunteer military force system. The government hopes that the new system not only can recruit promising voluntary soldiers, but that they also continue their military service after the contract expires in order to ensure stability in recruitment sources. This study explores the intention of voluntary soldiers to continue their military service. This study’s questionnaire encompasses five dimensions: Participation motivation, organization commitment, career planning, personality traits and departure tendency. The questionnaires were issued to 350 voluntary soldiers to explore if they intend to continue their service after their contract expires, with a total of 314 effective questionnaires that were recovered and analyzed. The results find that about half of the voluntary soldiers indicate that they do not plan on staying and continuing their service after contract expiration, which will result in understaffing in the military. In order to stabilize the prescribed number of soldiers, the existing recruiting policy and military management system should be re-adjusted.

    Introduction Internet-delivered psychological interventions among people with chronic pain have the potential to overcome environmental and economic barriers to the provision of evidence-based psychological treatment in the Irish health service context. While the use of internet-delivered cognitive–behavioural therapy programmes has been consistently shown to have small-to-moderate effects in the management of chronic pain, there is a paucity in the research regarding the effectiveness of an internet-delivered Acceptance and Commitment Therapy (ACT) programme among people with chronic pain. The current study will compare the clinical-effectiveness and cost-effectiveness of an online ACT intervention with a waitlist control condition in terms of the management of pain-related functional interference among people with chronic pain. Methods and analysis Participants with non-malignant pain that persists for at least 3 months will be randomised to one of two study conditions. The experimental group will undergo an eight-session internet-delivered ACT programme over an 8-week period. The control group will be a waiting list group and will be offered the ACT intervention after the 3-month follow-up period. Participants will be assessed preintervention, postintervention and at a 3-month follow-up. The primary outcome will be pain-related functional interference. Secondary outcomes will include: pain intensity, depression, global impression of change, acceptance of chronic pain and quality of life. A qualitative evaluation of the perspectives of the participants regarding the ACT intervention will be completed after the trial. Ethics and dissemination The study will be performed in agreement with the Declaration of Helsinki and is approved by the National University of Ireland Galway Research Ethics Committee (12/05/05). The results of the trial will be published according to the CONSORT statement and will be presented at conferences and reported in peer

    Although bilingual children frequently switch between languages, the psycholinguistic mechanisms underlying the emerging ability to control language choice are unknown. We examined the mechanisms of voluntary language switching in English-Spanish bilingual children during a picture-naming task under two conditions: 1) single-language naming in English and in Spanish; 2) either-language naming, when the children could use whichever language they wanted. The mechanism of inhibitory control was examined by analyzing local switching costs and global mixing costs. The mechanism of lexical accessibility was examined by analyzing the properties of the items children chose to name in their non-dominant language. The children exhibited significant switching costs across both languages and asymmetrical mixing costs; they also switched into their non-dominant language most frequently on highly accessible items. These findings suggest that both lexical accessibility and inhibition contribute to language choice during voluntary language switching in children. PMID:26889376

  9. Optimism as modifier of escalation of commitment.

    Juliusson, Asgeir

    2006-10-01

    To study whether optimism-pessimism modifies escalation of commitment, 52 undergraduates were told that they had made an unsuccessful investment, then they chose to continue or discontinue this investment. Optimism about future returns was induced in one group by varying the probability of a successful outcome from an initial low to medium, pessimism was induced in another group by varying this probability from an initial high to medium. Supporting the assumption of the manipulation, the results showed that optimistic participants preferred to continue investments whereas pessimistic participants preferred not to. As predicted, when the sunk cost increased, optimism led to escalation of commitment, whereas pessimism led to de-escalation of commitment. These effects were strengthened when probability of a successful outcome was ambiguous.

  10. Comparing Voluntary and Mandatory Gameplay

    Full Text Available Gameplay is commonly considered to be a voluntary activity. Game designers generally believe that voluntary gameplay is essentially different from mandatory gameplay. Such a belief may be a challenge for serious games, as instruction is usually mandatory. The article describes the outcomes of two experiments on the impact of voluntariness on the learning effect and enjoyment of a serious game. In the first experiment freedom of choosing to play a serious game was studied, with participants who had volunteered to participate. The results suggested that, contrary to the opinion of many game designers, being required to play a serious game does not automatically take the fun out of the game. The second experiment had voluntary participants and mandatory participants, who had to participate as part of a homework assignment. The outcomes show that mandatory participants enjoyed the game as much as the voluntary participants, even if they had to play the game for a minimum required time. These studies indicate that mandatory gameplay does not reduce enjoyment and learning effect.

  11. Voluntary organisation and adult education

    Full Text Available The author starts by offering a definition of voluntary organisations. He then discusses their importance and role, focusing on the issue of adult education wi­ thin these organisations. He also wells upon learning and change of voluntary organisation members, making use of the results of a study he conducted together with his collaborators. One of their fin­dings has been that voluntary organisati­ons, due to their organisational targets li­ke painting, singing or caring for people in need, lead their members to learning, i.e. essentially content learning. Moreo­ver, voluntary organisations offer a fair number of opportunities for social lear­ning and change. ln spite of the fact that the respondents were mostly not aware of the outcomes of their learning and change, careful listeners conducting the interview made them understand the im­portance of the learning they had gone through. The author concludes by poin­ ting out that formal education of adults can get its inspiration in learning in voluntary organisations. On the other hand, such learning would benefit greatly from findings and methods of formal education of adults.

    Most of us agree that people are our most important resource. Yet we spend a minimal amount of time learning more about human behavior, communication, and how our attitudes and behavior impact employee performance. Instead we rely on traditional methods of negative reinforcement in an attempt to control our areas of responsibility. While these methods can render some short-term success, managers and organizations that succeed during these times of change and fierce competition will be those that take the time to understand and capture the power of a committed workforce. The committed workforce is energized, not simply compliant, as a result of having basic human needs for achievement satisfied, belonging to a group, and receiving recognition for its contributions. Committed workers typically describe the manager as one who has the ability to give them a great degree of control over their area of influence. We all know that we don't change our leadership style like we change clothes. Old habits die hard. it takes a personal commitment and lots of practice to rid outselves of habits and behavior that no longer serve our departments and facilities. This commitment, however, is crucial to survival. As managers, we must cope with increasing ambiguity and uncertainty in the workplace. To survive these challenges, we must improve our interpersonal skills and ability to successfully bring out the best in others. I believe that success will continue for managers who not only increase their knowledge and technical ability, but who also inspire their workers to move forward with a collective sense of enthusiasm and purpose.

  17. Robust relativistic bit commitment

    2016-12-01

    Relativistic cryptography exploits the fact that no information can travel faster than the speed of light in order to obtain security guarantees that cannot be achieved from the laws of quantum mechanics alone. Recently, Lunghi et al. [Phys. Rev. Lett. 115, 030502 (2015), 10.1103/PhysRevLett.115.030502] presented a bit-commitment scheme where each party uses two agents that exchange classical information in a synchronized fashion, and that is both hiding and binding. A caveat is that the commitment time is intrinsically limited by the spatial configuration of the players, and increasing this time requires the agents to exchange messages during the whole duration of the protocol. While such a solution remains computationally attractive, its practicality is severely limited in realistic settings since all communication must remain perfectly synchronized at all times. In this work, we introduce a robust protocol for relativistic bit commitment that tolerates failures of the classical communication network. This is done by adding a third agent to both parties. Our scheme provides a quadratic improvement in terms of expected sustain time compared with the original protocol, while retaining the same level of security.

    A model of Unit Commitment to hydrothermal systems that includes the costs of start/stop of generators is proposed. These costs has been neglected in a good part of the programming models for operation of hydrothermal systems (pre-dispatch). The impact of the representation of costs in total production costs is evaluated. The proposed model is solved by a hybrid methodology, which involves the use of genetic algorithms (to solve the entire part of the problem) and sequential quadratic programming methods. This methodology is applied to the solution of an IEEE test system. The results emphasize the importance of representation of the start/stop in the generation schedule.

    An individual's loyalty or bond to his or her employing organization, referred to as organizational commitment, influences various organizational outcomes such as employee motivation, job satisfaction, performance, accomplishment of organizational goals, employee turnover, and absenteeism. Therefore, as in other sectors, employee commitment is crucial also in the healthcare market. This study investigates the effects of organizational factors and personal characteristics on organizational commitment of military physicians using structural equation modeling (SEM) on a self-report, cross-sectional survey that consisted of 635 physicians working in the 2 biggest military hospitals in Turkey. The results of this study indicate that professional commitment and organizational incentives contribute positively to organizational commitment, whereas conflict with organizational goals makes a significantly negative contribution to it. These results might help develop strategies to increase employee commitment, especially in healthcare organizations, because job-related factors have been found to possess greater impact on organizational commitment than personal characteristics.

    Acceptance and commitment therapy (ACT) is a third generation of cognitive-behavioral therapies. The point is to help patients to improve their psychological flexibility in order to accept unavoidable private events. Thus, they have the opportunity to invest energy in committed actions rather than struggle against their psychological events. (i) To present the ACT basic concepts and (ii) to propose a systematic review of the literature about effectiveness of this kind of psychotherapy. (i) The core concepts of ACT come from Monestès (2011), Schoendorff (2011), and Harris (2012); (ii) we conducted a systematic review of the literature using the PRISMA's criteria. The research paradigm was « acceptance and commitment therapy AND randomized controlled trial ». The bases of the MEDLINE, Cochrane and Web of science have been checked. Overall, 61 articles have been found, of which, after reading the abstracts, 40 corresponded to the subject of our study. (I) Psychological flexibility is established through six core ACT processes (cognitive defusion, acceptance, being present, values, committed action, self as context), while the therapist emphasizes on experiential approach. (II) Emerging research shows that ACT is efficacious in the psychological treatment of a wide range of psychiatric problems, including psychosis, depression, obsessive-compulsive disorder, trichotillomania, generalized anxiety disorder, post-traumatic stress disorder, borderline personality disorder, eating disorders. ACT has also shown a utility in other areas of medicine: the management chronic pain, drug-dependence, smoking cessation, the management of epilepsy, diabetic self-management, the management of work stress, the management of tinnitus, and the management of multiple sclerosis. Meta-analysis of controlled outcome studies reported an average effect size (Cohen's d) of 0.66 at post-treatment (n=704) and 0.65 (n=580) at follow-up (on average 19.2 weeks later).

    This presentation provides an overview of international voluntary renewable energy markets, with a focus on the United States and Europe. The voluntary renewable energy market is the market in which consumers and institutions purchase renewable energy to match their electricity needs on a voluntary basis. In 2010, the U.S. voluntary market was estimated at 35 terawatt-hours (TWh) compared to 300 TWh in the European market, though key differences exist. On a customer basis, Australia has historically had the largest number of customers, pricing for voluntary certificates remains low, at less than $1 megawatt-hour, though prices depend on technology.

    This research investigates the influence of shared perceptions of developmental climate on individual-level perceptions of organizational commitment, engagement, and perceived competence, and whether these attitudes mediate the relationship between developmental climate and both individual voluntary turnover and supervisor-rated job performance. Survey data were collected from 361 intact employee-supervisory mentoring dyads and matched with employee turnover data collected one year later to test the proposed framework using multilevel modeling techniques. As expected, shared perceptions of developmental climate were significantly and positively related to all three individual work attitudes. In addition, both organizational commitment and perceived competence were significant mediators of the positive relationship between shared perceptions of developmental climate and voluntary turnover, as well as shared perceptions of developmental climate and supervisor-rated job performance. By contrast, no significant mediating effects were found for engagement. Theoretical implications, limitations, and future research are discussed.

    2001-01-01

    This paper outlines the continuous improvement journey of a voluntary organisation. The significant level of organisational growth and improving quality of services described is clearly linked to the organisation's commitment to improvement. One of the approaches used in adopting a total quality culture was the EFQM model, specifically interpreted for the voluntary sector. Until recently such an approach would have been considered alien to the sector, not least because of its origins in the business community. This article contradicts this assumption. Issues addressed include how the improvement process is driven, the use of performance measurement, external verification and the difficulties in accessing sector appropriate benchmark data. It is suggested that the pursuit of excellence is no longer optional for the voluntary sector, it is essential.

    Quantum physics allows unconditionally secure communication between parties that trust each other. However, when they do not trust each other such as in the bit commitment, quantum physics is not enough to guarantee security. Only when relativistic causality constraints combined, the unconditional secure bit commitment becomes feasible. Here we experimentally implement a quantum bit commitment with relativistic constraints that offers unconditional security. The commitment is made through quantum measurements in two quantum key distribution systems in which the results are transmitted via free-space optical communication to two agents separated with more than 20 km. Bits are successfully committed with less than 5 . 68 ×10-2 cheating probability. This provides an experimental proof of unconditional secure bit commitment and demonstrates the feasibility of relativistic quantum communication.

  14. Strengthening affective organizational commitment: the influence of fairness perceptions of management practices and underlying employee cynicism.

    English, Brian; Chalon, Christopher

    2011-01-01

    This study investigates the relationship between cynicism, the perceived fairness of change management and personnel practices, and affective organizational commitment. High levels of affective organizational commitment have been shown to reduce voluntary turnover in the nursing workforce. Previous research suggests that "unfair" management practices and employee cynicism lead to lower commitment. It is not clear, however, whether the perceived fairness of particular practices influences affective commitment beyond that accounted for by underlying employee cynicism. Data were obtained from a study involving 1104 registered nurses that formed part of a larger investigation of the general well-being of nurses in Western Australia. Only nurses who were permanent or employed on fixed term or temporary contracts were included. Findings indicated that although higher levels of cynicism among nurses were associated with lower levels of affective commitment, their perception of the fairness of change management and personnel practices influenced their affective commitment over and above their cynicism. The perceived fairness of management practices is an important influence on nurses' affective commitment beyond that accounted for by cynicism. The implication for managers is that the affective organizational commitment of nurses is likely to be strengthened by addressing the perceived fairness of change management and personnel practices notwithstanding their beliefs about the integrity of the organization.

  1. Dynamics of Voluntary Cough Maneuvers

    Science.gov (United States)

    Naire, Shailesh

    2008-11-01

    Voluntary cough maneuvers are characterized by transient peak expiratory flows (PEF) exceeding the maximum expiratory flow-volume (MEFV) curve. In some cases, these flows can be well in excess of the MEFV, generally referred to as supramaximal flows. Understanding the flow-structure interaction involved in these maneuvers is the main goal of this work. We present a simple theoretical model for investigating the dynamics of voluntary cough and forced expiratory maneuvers. The core modeling idea is based on a 1-D model of high Reynolds number flow through flexible-walled tubes. The model incorporates key ingredients involved in these maneuvers: the expiratory effort generated by the abdominal and expiratory muscles, the glottis and the flexibility and compliance of the lung airways. Variations in these allow investigation of the expiratory flows generated by a variety of single cough maneuvers. The model successfully reproduces PEF which is shown to depend on the cough generation protocol, the glottis reopening time and the compliance of the airways. The particular highlight is in simulating supramaximal PEF for very compliant tubes. The flow-structure interaction mechanisms behind these are discussed. The wave speed theory of flow limitation is used to characterize the PEF. Existing hypotheses of the origin of PEF, from cough and forced expiration experiments, are also tested using this model.

  10. Committed warming inferred from observations

    Science.gov (United States)

    Mauritsen, Thorsten; Pincus, Robert

    2017-09-01

    Due to the lifetime of CO2, the thermal inertia of the oceans, and the temporary impacts of short-lived aerosols and reactive greenhouse gases, the Earth’s climate is not equilibrated with anthropogenic forcing. As a result, even if fossil-fuel emissions were to suddenly cease, some level of committed warming is expected due to past emissions as studied previously using climate models. Here, we provide an observational-based quantification of this committed warming using the instrument record of global-mean warming, recently improved estimates of Earth’s energy imbalance, and estimates of radiative forcing from the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. Compared with pre-industrial levels, we find a committed warming of 1.5 K (0.9-3.6, 5th-95th percentile) at equilibrium, and of 1.3 K (0.9-2.3) within this century. However, when assuming that ocean carbon uptake cancels remnant greenhouse gas-induced warming on centennial timescales, committed warming is reduced to 1.1 K (0.7-1.8). In the latter case there is a 13% risk that committed warming already exceeds the 1.5 K target set in Paris. Regular updates of these observationally constrained committed warming estimates, although simplistic, can provide transparent guidance as uncertainty regarding transient climate sensitivity inevitably narrows and the understanding of the limitations of the framework is advanced.

    Retaining newly graduated nurses is critical for organizations because of the significant cost of turnover. Since commitment to an organization is associated with decreased turnover intent, understanding factors that influence new graduates' organizational commitment is important. In a sample of nurse residency program participants, predictors of organizational commitment over time were explored. Perceptions of the work environment, particularly job satisfaction and job stress, were found to be most influential.

    2005-01-01

    A frequent case of irrational decision making is the tendency to escalate commitment to a chosen course of action after unsuccessful prior investments of money, effort, or time (sunk costs). In previous research it is argued that escalation does not occur when future outcomes and alternative investments are transparent. Inconsistent with this argument, in an experiment in which undergraduates were presented fictitious investment problems with sunk costs, escalation was demonstrated when full information was given about investment alternatives and estimates of future returns. Thus, it is indicated that people may escalate despite knowing that it will not make them economically better off. A more comprehensive understanding of escalation requires disentangling people's noneconomic reasons for escalation.

  13. Motivation in Italian whole blood donors and the role of commitment.

    Bani, Marco; Strepparava, Maria Grazia

    2011-12-01

    The literature contains numerous reports on motivation in blood donors, although none of these are specific to blood donation in Italy and almost all of them focus on altruism and the desire to help others. Altruism is important, but a comprehensive analysis of donor motivation should examine all the factors affecting the decision to donate, including commitment to voluntary blood donor organizations. The aims of this paper are to verify if the motivational factors that influence the choice to donate blood in Italy are generally consistent with the findings from other countries reported in the literature and to focus on commitment to donor organizations as an additional factor. A sample of 895 whole blood donors completed a self-report questionnaire containing questions about: reasons for beginning to donate, people who influenced this choice, and level of commitment to voluntary blood donor organizations. The most frequently reported reasons for giving blood for the first time were "to help others" (56%), "influence of family/friends" (22%), and "social/moral obligation" (11.2%); commitment did not vary as a function of the leading motivation reported. Differences emerged between males, who more frequently reported having been influenced by parents and friends, and females, who referred more often to altruistic motives. The opportunity to check one's own state of health also played an important role (6.9%), especially for male donors. Overall, however, the decision to donate was primarily a personal choice (41.3%), although influence was also attributed to relatives (21.8%), friends (22.3%), and voluntary blood donor organizations (21.8%). The reported level of commitment to the donor organization was positively correlated with the number of total and annual donations made and number of new donors recruited.

    Production cost models (PCMs) simulate power system operation at hourly (or higher) resolution. While computation times often extend into multiple days, the sequential nature of PCM's makes parallelism difficult. We exploit the persistence of unit commitment decisions to select partition boundaries for simulation horizon decomposition and parallel computation. Partitioned simulations are benchmarked against sequential solutions for optimality and computation time.

  18. The impact of work rewards on radiographers' organizational commitment.

    1995-01-01

    Organizational commitment is an affective work outcome that has been used to predict work-related behaviors such as turnover, absenteeism and intent-to-leave. There has been little research in organizational commitment for the allied health professions and no empirical studies in the radiologic sciences. The purpose of this study was to examine the predictive value of selected intrinsic and extrinsic work reward variables--involvement, significance, autonomy, general working conditions, supervision and salary--on staff radiographers' organizational commitment. In this study of 600 full-time staff radiographers in North and South Carolina, supervision (for ages 20-37 years) and involvement (for ages 38-66 years) were significant predictors of organizational commitment. The results of the study indicate that healthcare organizations should provide potential supervisors with managerial training, especially for radiographers who move to supervisory positions based on clinical skills and years of experience. In the long run, such programs are much less expensive than costs associated with replacing employees who leave the organization because of low organizational commitment. Also, management strategies and programs to redesign and enhance job tasks may help maintain or increase organizational commitment.

  20. The impact of quality of work life on job embeddedness and affective commitment and their co-effect on turnover intention of nurses.

    To verify with empirical evidence the hypothesised relation and the effect of quality of work life, job embeddedness and affective commitment on turnover intention of clinical nurses in China. High turnover of the nursing workforce in healthcare organisations is a difficult and recurring problem in China as well as in many other countries in the world. It leads to great waste of resources and increases management cost. Developing and retaining the nursing workforce, which is a major challenge faced by human resources practitioners in hospitals and public health agencies, also becomes a subject of interest for management studies. Most of the literature about voluntary turnover focused on such traditional measures as job satisfaction and job alternatives in the past. The introduction of such new concepts as quality of work life, job embeddedness and affective commitment, which views the issue from a much broader and comprehensive spectrum, made a great breakthrough in the turnover study. In this study, we selected quality of work life, job embeddedness and affective commitment - three of the most important factors in employer-employee relations - and analysed the interaction between each one of them, as well as their co-effect on turnover intention of Chinese nurses. Cross-sectional survey and structural equation modelling were applied in studying the self-report questionnaires distributed to 1000 nurses employed in five large-scale government-owned hospitals in Heilongjiang Province, Northeast China. Our study confirmed the hypothesised positive relation of quality of work life with job embeddedness and affective commitment and the hypothesised negative relation of quality of work life with turnover intention, that is, high quality of work life perceived by the nurses enhances their job embeddedness and affective commitment and thus reduces their intention to leave the job. The effect of quality of work life is positive on job embeddedness and affection commitment

  3. Job Insecurity and Organizational Commitment

    Directory of Open Access Journals (Sweden)

    Bengt Furåker

    2015-01-01

    Full Text Available This article deals with the relationship between job insecurity and organizational commitment. Our analysis includes both ‘subjective’ and ‘objective’ measures of job insecurity and it also distinguishes between a cognitive and affective component of the subjective dimension. As to organizational commitment, we make a distinction between value commitment and readiness to remain with the employing organization. The empirical basis for the analysis is survey data collected in Sweden in 2010-2011. Some of the outcomes are just as expected: perceived risk of losing one’s job is associated with lower value commitment and less willingness to stay with the organization, while the opposite pattern appears for satisfaction with job security. Other results are more noteworthy: increases in unemployment, temporary employment contracts and worry about losing one’s job are linked to higher value commitment. Being anxious about job loss is also positively related to willingness to stay. These results indicate that insecurity can make people more appreciative of their current work and workplace.

    2009-03-04

    Voluntary memory suppression can keep unwanted memories from entering consciousness, inducing later forgetting of the information. In the present study, we searched for the existence of anticipatory processes, mediating such voluntary memory suppression. Using the think/no-think paradigm, subjects received a cue whether to prepare to think of a previously studied cue-target pair or whether to not let a previously studied cue-target pair enter consciousness. Examining event-related potentials, we identified two electrophysiological processes of voluntary memory suppression: (1) an early anticipatory process operating before the memory cue for a to-be-suppressed memory was provided, and (2) a later process operating after memory cue presentation. Both ERP effects were due to a decreased right frontal and left parietal positivity. They were positively related and predicted later forgetting. The results point to the existence of anticipatory processes, mediating voluntary memory suppression.

This is not surprising at all, because it is highly profitable according to the related estimated data. There are 115,9 million people doing voluntary work only in Europe, which means that they would create the world's 7th biggest economy with EUR 282 billion value creation if they formed an individual state. The organizations know that voluntary work has several advantages apart from the economic benefits. It is profitable both for the society and for the individuals as well. Several researches have proven that voluntary work positively influences the development of the personality, because the key-competencies - such as: co-operation, empathy, solidarity, conflict handling, problem solving, etc. - expected in the labor market can be improved.

    2016-09-01

    Bit commitment is a fundamental cryptographic primitive in which a party wishes to commit a secret bit to another party. Perfect security between mistrustful parties is unfortunately impossible to achieve through the asynchronous exchange of classical and quantum messages. Perfect security can nonetheless be achieved if each party splits into two agents exchanging classical information at times and locations satisfying strict relativistic constraints. A relativistic multiround protocol to achieve this was previously proposed and used to implement a 2-millisecond commitment time. Much longer durations were initially thought to be insecure, but recent theoretical progress showed that this is not so. In this Letter, we report on the implementation of a 24-hour bit commitment solely based on timed high-speed optical communication and fast data processing, with all agents located within the city of Geneva. This duration is more than 6 orders of magnitude longer than before, and we argue that it could be extended to one year and allow much more flexibility on the locations of the agents. Our implementation offers a practical and viable solution for use in applications such as digital signatures, secure voting and honesty-preserving auctions.

    Full Text Available This paper provides a new way to identify conditional cooperation in a real-time version of the standard voluntary contribution mechanism. We define contribution cycles as the number of contributors a player waits for before committing to a further contribution, and use a permutation test on contribution cycles to assign a measure of conditional cooperation to each group play. The validity of the measures is tested in an experiment. We find that roughly 20% of the plays exhibit dynamics of conditional cooperation. Moreover, notwithstanding a decline in contributions, conditional cooperation is found to be stable over time.

    Mobbing of predators occurs within a conspecific and heterospecific context but has not been quantified within the framework of a communication network and analysed with respect to heterospecific reciprocity. Here, we used playbacks of mobbing calls to show that mobbing is unequally distributed within a community of deciduous forest birds. Five species (great tit Parus major, blue tit Cyanistes caeruleus, marsh tit Poecile palustris, nuthatch Sitta europaea and chaffinch Fringilla coelebs) responded to each other's playbacks of mobbing calls. Commitment to mob was measured by minimum distance, response latency and uttering of calls. Commitment was higher when conspecific calls were broadcast. Yet, responses to heterospecific calls were significantly different between the five species. Chaffinches had the lowest commitment, and blue tits tended to have the highest. The communication network is asymmetric. Some species invest more than they receive from other species. As mobbing might incur costs, these are unequally distributed across the community.

    2003-07-01

    This report presents an analysis of the potential for making voluntary agreements between the Danish state, the counties and the municipalities with the purpose of reducing CO{sub 2} emissions from the transport sector. Voluntary agreements focusing on the use of local means could lead to an estimated reduction of almost 5000,000 tonnes CO{sub 2}, if Danish municipalities make a one-time investment of 600 million DKK. Compared to Denmark's CO{sub 2} commitments following the ratification of the Kyoto Protocol, 500,000 tonnes constitute a rather small but still appreciable amount of CO{sub 2}. It is argued that, presently, Danish municipalities cannot identify appropriate political and economical incentives to launch a specific CO{sub 2} initiative and, finally, it is concluded that the cost-effectiveness of using local means specifically targeted at CO{sub 2} is far too low compared to other means such as using the flexible mechanisms outlined in the Kyoto Protocol. It is problematic to politically legitimate measures that focus specifically on the use of local means to reduce CO{sub 2} emissions from the transport sector. If a wider focus is accepted, including focus on additional effects such as reduced air pollution, reduced number of traffic accidents and improved health, the cost-effectiveness assessment would look rather different and offer more legitimacy to the use of local means in Danish municipalities. A hitch-hiking strategy should be introduced in both existing and coming local spatial planning activities. One example could be the mandatory local Agenda 21 strategies that Danish municipalities must prepare according to the Danish Planning Act. Another example could be strategic environmental assessments of programmes and plans that are introduced in the European Union SEA Directive. In the report it is argued that if a voluntary agreement initiative, with the purpose of introducing CO{sub 2} hitch-hiking strategies in local spatial planning, is

    Voluntary covert attention selects relevant sensory information for prioritized processing. The behavioral and neural consequences of such selection have been extensively documented, but its phenomenology has received little empirical investigation. Involuntary attention increases perceived spatial frequency (Gobell & Carrasco, 2005), but involuntary attention can differ from voluntary attention in its effects on performance in tasks mediated by spatial resolution (Yeshurun, Montagna, & Carrasco, 2008). Therefore, we ask whether voluntary attention affects the subjective appearance of spatial frequency--a fundamental dimension of visual perception underlying spatial resolution. We used a demanding rapid serial visual presentation task to direct voluntary attention and measured perceived spatial frequency at the attended and unattended locations. Attention increased the perceived spatial frequency of suprathreshold stimuli and also improved performance on a concurrent orientation discrimination task. In the control experiment, we ruled out response bias as an alternative account by using a lengthened interstimulus interval, which allows observers to disengage attention from the cued location. In contrast to the main experiment, the observers showed neither increased perceived spatial frequency nor improved orientation discrimination at the attended location. Thus, this study establishes that voluntary attention increases perceived spatial frequency. This phenomenological consequence links behavioral and neurophysiological studies on the effects of attention.

    Although previous research indicates that participation in a brand community may foster consumer loyalty to the brand in question, research has seldom examined the mediating effect of community commitment on brand commitment. Drawing from the typologies of organizational commitment, we divide community commitment into three components: continuance community commitment (continuance CC), affective community commitment (affective CC), and normative community commitment (normative CC). We then assess the mediating role of brand attachment in the relationship between these three components and brand commitment. We test the hypotheses using a sample of online mobile phone brand communities in China. The empirical results reveal that brand attachment exerts an indirect (but not mediated) effect on the relationship between continuance CC and brand commitment and on the relationship between normative CC and brand commitment. We also find that it exerts a partial mediating effect on the relationship between affective CC and brand commitment. The findings contribute to the branding literature and have important implications for brand community management.

    In 2010, approximately 500,000 Canadians suffered from a dementia-related illness. The number of sufferers is estimated to double in about 25 years. Due to this growing demographic, dementia (most frequently caused by Alzheimer's disease) will increasingly have a significant impact on our aging community and their caregivers. Dementia is associated with challenging behaviours such as agitation, wandering, and aggression. Care providers must find innovative strategies that facilitate the quality of life for this population; moreover, such strategies must value the individual person. Social commitment robots - designed specifically with communication and therapeutic purposes - provide one means towards attaining this goal. This paper describes a study in which Paro (a robotic baby harp seal) was used as part of a summer training program for students. Preliminary conclusions suggest that the integration of social commitment robots may be clinically valuable for older, agitated persons living with dementia in long-term care settings.

    1992-03-01

    Full Text Available How Much to Commit to an Exchange Rate Rule? Balancing Credibility and Flexibility There are different ways in which policy-makers back their commitment to a fixed exchange rate. A regime where countries can devalue unilaterally represents a weaker commitment than one where a devaluation needs to be agreed upon with other parties (e.g. the European monetary system. Full dollarization, understood here as full replacement of the domestic currency by the U.S. dollar, is an extreme commitment to a fixed exchange rate. Indeed, it is a especial case of a fixed exchange rate.The central message of this paper is that the cost of reneging is a key reason holding policymakers back from making strong commitments on their exchange rate policy. The stronger the commitment to an exchange rate rule, the more costly it is to deviate from it. The paper develops a Barro-Gordon type model in which the policymaker has to decide the degree of commitment under uncertainty.It is shown that, even for policy makers that have a strong preference for maintaining the fixed exchange rate, there are circunstances under which they will choose to devalue. This will happen when the economy is hit by an adverse shock and the costs of adhering to the fixed exchange rate are larger than those associated with devaluing.The model provides useful insights to understand why many high inflation economies have not adopted full dollarizarion as a way to stabilize prices. Our emphasis on the cost of reneging stands in contrast with most existing works, which single out the desire to rely on seigniorage as the main motive for stopping short of full dollarization. Strong commitments will only be made once there is a good chance that the policy maker will not renege, and by then they might not be necessary. We illustrate the main points of the paper with examples from Latin American countries.

  20. The relevance of ontological commitments

    Echenique-Robba, Pablo

    2014-01-01

    In this introductory note, I describe my particular view of the notion of ontological commitments as honest and pragmatic working hypotheses that assume the existence (out there) of certain entities represented by the symbols in our theory. I argue that this is not naive, in the sense that it does not entail the belief that the hypotheses could ever be proved to be true (or false), but it is nevertheless justified by the success and predictive power of the theory that contains the concepts assumed to exist. I also claim that the ontological commitments one holds (even if tacitly so) have a great influence on what kind of science is produced, how it is used, and how it is understood. Not only I justify this claim, but I also propose a sketch of a possible falsification of it. As a natural conclusion, I defend the importance of identifying, clarifying and making explicit one's ontological commitments if fruitful scientific discussions are to be had. Finally, I compare my point of view with that of some philosop...

  2. Spermatogenesis: The Commitment to Meiosis.

    Science.gov (United States)

    Griswold, Michael D

    2016-01-01

    Mammalian spermatogenesis requires a stem cell pool, a period of amplification of cell numbers, the completion of reduction division to haploid cells (meiosis), and the morphological transformation of the haploid cells into spermatozoa (spermiogenesis). The net result of these processes is the production of massive numbers of spermatozoa over the reproductive lifetime of the animal. One study that utilized homogenization-resistant spermatids as the standard determined that human daily sperm production (dsp) was at 45 million per day per testis (60). For each human that means ∼1,000 sperm are produced per second. A key to this level of gamete production is the organization and architecture of the mammalian testes that results in continuous sperm production. The seemingly complex repetitious relationship of cells termed the "cycle of the seminiferous epithelium" is driven by the continuous commitment of undifferentiated spermatogonia to meiosis and the period of time required to form spermatozoa. This commitment termed the A to A1 transition requires the action of retinoic acid (RA) on the undifferentiated spermatogonia or prospermatogonia. In stages VII to IX of the cycle of the seminiferous epithelium, Sertoli cells and germ cells are influenced by pulses of RA. These pulses of RA move along the seminiferous tubules coincident with the spermatogenic wave, presumably undergoing constant synthesis and degradation. The RA pulse then serves as a trigger to commit undifferentiated progenitor cells to the rigidly timed pathway into meiosis and spermatid differentiation.

    Full Text Available The present study was designed to investigate hemochromatosis patients' suitability as blood donors as well as their perceptions and experience with the current public donation system. Participants were gathered from a list of current hemochromatosis patients (n=120 and members of the Canadian Hemochromatosis Society (n=1000. Of the 1120 surveys mailed out to these groups, 801 surveys were returned completed. The sample respondents had a mean age of 57.44 years (SD=12.73; range 19 to 87 years, and 57% were men. It was found that 20% (160 of the respondents have donated blood since their diagnosis; however, only 12% of the respondents indicated that they use voluntary blood donation as a means of maintaining their iron levels. Forty per cent of the respondents indicated that they had been refused from voluntary donation. Despite the fact that in May 2001 the Canadian Blood Services, in collaboration with the Canadian Hemochromatosis Society, began a promotion campaign to encourage hemochromatosis patients to become voluntary blood donors, the present study found that 15% of the respondents reported having been refused from the voluntary blood donation service due to the diagnosis of hemochromatosis. With respect to quality of life, it was found that individuals who donate blood were generally healthier with respect to physical functioning and bodily pain, however, these findings may indicate that hemochromatosis patients who are healthier are better able to donate at public blood banks, rather than that voluntary blood donation has an effect on the donors' physical functioning over phlebotomy clinic users. These study findings suggest that although there may be other medical factors limiting individuals from donating, hemochromatosis patients are interested in being voluntary blood donors and this potential resource is currently under-used.

    The purpose of this study was to examine the impact of selected organizational factors and the leadership behavior of supervisors on radiation therapists' commitment to their organizations. The population for this study consists of all full time clinical radiation therapists registered by the American Registry of Radiologic Technologists (ARRT) in the United States. A random sample of 800 radiation therapists was obtained from the ARRT for this study. Questionnaires were mailed to all participants and measured organizational variables; managerial leadership variable and three components of organizational commitment (affective, continuance and normative). It was determined that organizational support, and leadership behavior of supervisors each had a significant and positive affect on normative and affective commitment of radiation therapists and each of the models predicted over 40% of the variance in radiation therapists organizational commitment. This study examined radiation therapists' commitment to their organizations and found that affective (emotional attachment to the organization) and normative (feelings of obligation to the organization) commitments were more important than continuance commitment (awareness of the costs of leaving the organization). This study can help radiation oncology administrators and physicians to understand the values their radiation therapy employees hold that are predictive of their commitment to the organization. A crucial result of the study is the importance of the perceived support of the organization and the leadership skills of managers/supervisors on radiation therapists' commitment to the organization.

    2004-01-01

    Full Text Available The purpose of this research was to test the hypothesis that relations between fairness perception of human resource management (HRM practices and organizational commitment are affected by the quality of leader-member exchange (LMX. Specifically, we predicted the unique (positive contribution of fairness perception of HRM practices and LMX as well as their interaction to organizational commitment. A sample of 224 managers was drawn from nine diverse multinational, manufacturing companies located in Northern Malaysia. Participation in the research was voluntary. Data were gathered by means of a survey questionnaire that consisted of a series of psychometrically sound scales to assess the employed variables in the study. Hierarchical multiple regression results provided support for the direct impact of fairness perceptions and LMX on each component of commitment. But significant interactions were convincingly evident only in the case of affective commitment. These interactions suggest that the impact of fairness perceptions of HRM practices on affective commitment is not unconditional. Key implications of the survey findings both for theory and practice are discussed, potential limitations are specified, and directions for future research are suggested.

    This paper introduces the scheduling method for thermal and energy storage system (ESS) unit commitment. The ESS is incorporated to achieve peak load-levelling and reduce the total cost. The thermal scheduling is implemented by the extended priority list (EPL) method. The EPL method consists of two steps, in the first step we get rapidly some initial unit commitment schedules by the priority list (PL) method. In this step, operational constraints are disregarded. In the second step, unit schedules are modified using the problem specific heuristics to fulfill operational constraints and to reduce the total cost. To calculate efficiently, heuristics are only applied to solutions which can be expected improvement. The ramp constraints for thermal unit are considered at the last of EPL method. The ESS scheduling is carried out based on the thermal unit schedule obtained by the EPL method. Several numerical examples demonstrate the effectiveness of the proposed method. (author)

    Many studies have shown that the direction of gaze of a face covertly facilitates the response to a target presented in the matching direction. In this study we seek to determine whether there exist separate reflexive and voluntary forms of such covert social orienting and how they interact with each other. We measured the effect of the predictive value of a gaze cue on manual choice reaction times. When the predictive value of the gaze cue was zero, a facilitatory cueing effect was still observed which peaked at a cue onset to target onset delay (CTD) of 150ms and largely diminished beyond a CTD of 500ms. When the gaze cue was 100% predictive of the future location of the target, at CTDs greater than 200, the predictive cue resulted in a significantly greater facilitation of response than occurred with a non-predictive cue. These results suggest that given enough time (about 200ms), the social cue is interpreted and a willful or voluntary spatially-specific social cueing effect occurs. In addition, we found that a predictive cue resulted in a significant slowing of the observer's responses up to a CTD of 200ms. These findings show that, similar to non-social spatial orienting, there appear to be two forms of social orienting including a reflexive component and voluntary component. We suggest a model of social orienting in which the voluntary social orienting system modulates tonic inhibition of the reflexive social orienting system. Published by Elsevier Ltd.

    Gavage is a widely performed technique for daily dosing in laboratory rodents. Although effective, gavage comprises a sequence of potentially stressful procedures for laboratory animals that may introduce bias into experimental results, especially when the drugs to be tested interfere with stress-dependent parameters. We aimed to test vehicles suitable for drug delivery by voluntary ingestion in rats. Specifically, Male Wistar rats (age, 2 to 3 mo) were used to test nut paste (NUT), peanut butter (PB), and sugar paste (SUG) as vehicles for long-term voluntary oral administration of losartan, an angiotensin II receptor blocker. Vehicles were administered for 28 d without drug to assess effects on the glucose level and serum lipid profile. Losartan was mixed with vehicles and either offered to the rats or administered by gavage (14 d) for subsequent quantification of losartan plasma levels by HPLC. After a 2-d acclimation period, all rats voluntarily ate the vehicles, either alone or mixed with losartan. NUT administration reduced blood glucose levels. The SUG group had higher concentrations of losartan than did the gavage group, without changes in lipid and glucose profiles. Our results showed that NUT, PB, and SUG all are viable for daily single-dose voluntary ingestion of losartan and that SUG was the best alternative overall. Drug bioavailability was not reduced after voluntary ingestion, suggesting that this method is highly effective for chronic oral administration of losartan to laboratory rodents.

  3. Voluntary sterilization in Serbia: Unmet need?

    Rašević Mirjana M.

    2002-01-01

    Full Text Available Is voluntary sterilization as a birth control method accepted in Serbia? This is certainly a question that is being imposed for research, regardless of the fact that voluntary sterilization is neither accessible nor promoted. Most importantly because there is no understanding in the social nor political sphere for legalization of voluntary sterilization as a form of birth control, apart from the clear necessity for this, first, step. They are: the recognition that voluntary sterilization is an efficient and safe birth control method, respectability of basic human as well as sexual and reproductive rights, spreading of sterilization as a form of birth control among population of both developed and developing countries and an epidemic diffusion of repeated induced abortions in Serbia. Thus individual recognition of the advantages of relying on voluntary sterilization, in a non-encouraging atmosphere, certainly represents one more argument to enable couples to prevent conception by sterilization. Since it was impossible to carry out a representative research among the population of men and women who are at risk for conception, an attempt was made to obtain a reply to the set question among women who decided to induce abortion. It was done out of at least two reasons. The first being that women with induced abortion in their reproductive history were the target group for voluntary sterilization. The second reason was based on the assumption that bringing a decision on induced abortion is preceded by the reconsideration of an earlier adopted strategy regarding children, giving birth and contraception and thus its rational component is revealed more and therefore more easily measurable. The research was carried out in the University Clinic of Obstetrics and Gynecology 'Narodni front' in Belgrade from January 21st o March 1st 2002, and included 296 women. By comparing the social and demographic characteristics of the female respondents, as well as

    Here, we compared motor evoked potentials (MEP) in response to transcranial magnetic stimulation of the motor cortex and the H-reflex during voluntary and vibration-induced air-stepping movements in humans. Both the MEPs (in mm biceps femoris, rectus femoris and tibialis anterior) and H-reflex (in m soleus) were significantly smaller during vibration-induced cyclic leg movements at matched amplitudes of angular motion and muscle activity. These findings highlight differences between voluntary and non-voluntary activation of the spinal pattern generator circuitry in humans, presumably due to an extra facilitatory effect of voluntary control/triggering of stepping on spinal motoneurons and interneurons. The results support the idea of active engagement of supraspinal motor areas in developing central pattern generator-modulating therapies. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  8. Moving from voluntary euthanasia to non-voluntary euthanasia: equality and compassion.

    Science.gov (United States)

    Amaraskekara, Kumar; Bagaric, Mirko

    2004-09-01

    The recent Dutch law legalising active voluntary euthanasia will reignite the euthanasia debate. An illuminating method for evaluating the moral status of a practice is to follow the implications of the practice to its logical conclusion. The argument for compassion is one of the central arguments in favour of voluntary active euthanasia. This argument applies perhaps even more forcefully in relation to incompetent patients. If active voluntary euthanasia is legalised, arguments based on compassion and equality will be directed towards legalising active non-voluntary euthanasia in order to make accelerated termination of death available also to the incompetent. The removal of discrimination against the incompetent has the potential to become as potent a catch-cry as the right to die. However, the legalisation of non-voluntary euthanasia is undesirable. A review of the relevant authorities reveals that there is no coherent and workable "best interests" test which can be invoked to decide whether an incompetent patient is better off dead. This provides a strong reason for not stepping onto the slippery path of permitting active voluntary euthanasia.

  12. Virtual machine migration in an over-committed cloud

    KAUST Repository

    Zhang, Xiangliang

    2012-04-01

    While early emphasis of Infrastructure as a Service (IaaS) clouds was on providing resource elasticity to end users, providers are increasingly interested in over-committing their resources to maximize the utilization and returns of their capital investments. In principle, over-committing resources hedges that users - on average - only need a small portion of their leased resources. When such hedge fails (i.e., resource demand far exceeds available physical capacity), providers must mitigate this provider-induced overload, typically by migrating virtual machines (VMs) to underutilized physical machines. Recent works on VM placement and migration assume the availability of target physical machines [1], [2]. However, in an over-committed cloud data center, this is not the case. VM migration can even trigger cascading overloads if performed haphazardly. In this paper, we design a new VM migration algorithm (called Scattered) that minimizes VM migrations in over-committed data centers. Compared to a traditional implementation, our algorithm can balance host utilization across all time epochs. Using real-world data traces from an enterprise cloud, we show that our migration algorithm reduces the risk of overload, minimizes the number of needed migrations, and has minimal impact on communication cost between VMs. © 2012 IEEE.

  13. How do small business managers influence employee satisfaction and commitment?

    Directory of Open Access Journals (Sweden)

    Janine Kruger

    2010-12-01

    Full Text Available Purpose : The purpose of this research is to scrutinise motivational factors that may influence the levels of satisfaction and commitment of small business employees. Problem investigated : An unmotivated workforce leads to dissatisfaction and low commitment levels among employees. Possible consequences of these unproductive trends include higher costs, business closures and a negative effect on a country's economy. Employee satisfaction and employee commitment are thus vital for the success of any business. It is essential for business managers to keep their employees satisfied and committed to the business. In order for business managers to motivate their employees to keep them satisfied and committed, they need to know how to motivate employees. A number of factors influence employee satisfaction and employee commitment, which include working conditions, managerial abilities, employee participation, company policies, recognition and feedback, as well as job interest and job importance. Managers should know how to apply each of these factors to ensure that employees are satisfied and committed. Methodology : A quantitative research approach was followed using a self-administered questionnaire. This measuring instrument consisted of three sections covering the biographical information of respondents, statements on motivational factors, and statements about satisfaction and commitment. A five-point Likert-type scale, ranging from strongly disagree to strongly agree, was applied. Simple random sampling was used to elicit the responses of 444 respondents from small businesses in the Nelson Mandela Metropole in South Africa. Cronbach Alpha coefficients were calculated to measure the internal consistency and reliability of the measuring instrument. Descriptive statistics, Pearson correlation coefficients and simple linear regression analyses were used to analyse the data. Findings and implications : The research revealed that significant positive

  14. The Query-commit Problem

    CERN Document Server

    Molinaro, Marco

    2011-01-01

    In the query-commit problem we are given a graph where edges have distinct probabilities of existing. It is possible to query the edges of the graph, and if the queried edge exists then its endpoints are irrevocably matched. The goal is to find a querying strategy which maximizes the expected size of the matching obtained. This stochastic matching setup is motivated by applications in kidney exchanges and online dating. In this paper we address the query-commit problem from both theoretical and experimental perspectives. First, we show that a simple class of edges can be queried without compromising the optimality of the strategy. This property is then used to obtain in polynomial time an optimal querying strategy when the input graph is sparse. Next we turn our attentions to the kidney exchange application, focusing on instances modeled over real data from existing exchange programs. We prove that, as the number of nodes grows, almost every instance admits a strategy which matches almost all nodes. This resu...

    Ekeland, Ivar

    2007-01-01

    In this paper, we investigate the Merton portfolio management problem in the context of non-exponential discounting. This gives rise to time-inconsistency of the decision-maker. If the decision-maker at time t=0 can commit his/her successors, he/she can choose the policy that is optimal from his/her point of view, and constrain the others to abide by it, although they do not see it as optimal for them. If there is no commitment mechanism, one must seek a subgame-perfect equilibrium strategy between the successive decision-makers. In the line of the earlier work by Ekeland and Lazrak we give a precise definition of equilibrium strategies in the context of the portfolio management problem, with finite horizon, we characterize it by a system of partial differential equations, and we show existence in the case when the utility is CRRA and the terminal time T is small. We also investigate the infinite-horizon case and we give two different explicit solutions in the case when the utility is CRRA (in contrast with t...

    This study aimed to understand the current scenario of voluntary vaccination and the factors influencing its coverage among 18-month-old children of Takatsuki City, Japan. Based on 1167 parents responses, we found that voluntary vaccination coverage rates were low when compared with routine vaccination rates. The children who were not the first born of the family and who had young and poorly educated parents were less likely to receive voluntary vaccination. Japanese government-supported vaccines, such as Haemophilus influenzae type b and pneumococcal vaccine, had a higher coverage than the vaccines for which parents had to bear the entire vaccination cost. Furthermore, it was found that mass communication media and family pediatricians were effective means to disseminate voluntary vaccination-related information. We envisage that an active participation of medical professionals, easy access to vaccinations, and mass awareness programs will increase voluntary vaccination coverage in Takatsuki.

  18. A hybrid approach based on EP and PSO for proficient solving of Unit Commitment Problem

    R LAL RAJA SINGH,

    2011-06-01

    Full Text Available Unit Commitment Problem (UCP is a nonlinear mixed integer optimization problem used in the scheduling operation of power systemgenerating units subjected to demand and reserve requirement constraints for achieving minimum operating cost. The task of the UCproblem is to determine the on/off state of the generating units at every hour interval of the planning period for optimally transmitting the load and reserve among the committed units. The importance for the necessity of a more effective optimal solution to the UCP problem is increasing with the regularly varying demand. Hereby, we propose a hybrid approach which solves the unit commitment problem subjectedto necessary constraints and gives the optimal commitment of the units. The possible combination of demand and their correspondingoptimal generation schedule can be determined by the PSO algorithm. Being a global optimization technique, Evolutionary Programming(EP for solving Unit Commitment Problem, operates on a method, which encodes each unit’s operating schedule with respect to up/down time. When the demand over a time horizon is given as input to the network it successfully gives the schedule of each unit’s commitment that satisfies the demands of all the periods and results in minimum total cost. Because hybridization is dominating, this approach for solving the unit commitment problem is more effective.

    Herberholz, Chantal; Fakihammed, Wael Ahmed

    2017-04-01

    Low enrolment and high drop-out rates are common problems in voluntary health insurance schemes. Yet, most studies in this research area focus on community-based health insurance and enrolment, rather than drop-out. This study examines what causes informal sector families not to renew their voluntary National Health Insurance Fund (NHIF) health insurance membership in Eastern Sudan. Primary data from about 600 informal sector households that dropped out or remained insured, collected through a household survey conducted in March 2014, were used. Logistic regressions were employed to examine what determines drop-out of the voluntary NHIF scheme. The logistic regression results are consistent with the existing literature and confirm the importance of household head, household and community characteristics. Notably, worse family health status and higher health care utilization decrease the probability of drop-out, which requires further analysis as it may indicate the problem of adverse selection and insufficient risk management. Most importantly, the results consistently show that household heads who are satisfied with health services and those who understand the main features of the voluntary NHIF scheme are less likely to drop out. Also, 30 % of drop-out households hold a social support card and reported that the social support scheme is the main reason for not renewing their voluntary NHIF health insurance membership as they qualify for sponsored NHIF health insurance membership. This study shows that satisfaction with health services and knowledge of the health insurance scheme are important factors explaining drop-out of a national health insurance programme. The results suggest that education and information campaigns should be developed further to raise understanding of the NHIF voluntary scheme. In addition, information systems and coordination between the main agencies should be strengthened to reduce administrative costs and ensure policy coherence.

In 1998, 156 US companies and other organizations reported to the Energy information Administration that, during 1997, they had achieved greenhouse gas emission reductions and carbon sequestration equivalent to 166 million tons of carbon dioxide, or about 2.5% of total US emissions for the year. For the 1,229 emission reduction projects reported, reductions usually were measured by comparing an estimate of actual emissions with an estimate of what emissions would have been had the project not been implemented.

  8. The Political Importance of Voluntary Work.

    Science.gov (United States)

    Kunneman, Harry

    This paper aims to develop a complex articulation of the civic meaningfulness of voluntary work that clarifies its political importance as a countervailing narrative pointing beyond dominant neoliberal and consumptive articulations of a good life. To start with, it sketches a hermeneutic perspective on civic meaningfulness based on the work of Paul Ricoeur. Subsequently, it introduces the ideas of 'ethical complexity', 'epistemological complexity' and 'diapoiesis', building on insights from critical complexity thinking and relational biology. It argues that these notions can provide a bridge between hermeneutic perspectives on meaning and values, on the one hand, and questions of meaning and values on the level of scientific and technological developments and within professional organizations, on the other. Thus a broader, more complex picture emerges of the civic meaningfulness of voluntary work in our times.

    2016-09-01

    Historically, in France, cancer associations have been managed by doctors. Despite this, the French healthcare system has increasingly encouraged them to attract voluntary helpers who are not health workers. This development has given rise to the question of the competence and legitimacy of voluntary workers in cancer associations. The aim of the present study was to identify the skills possessed by voluntary helpers who have survived the disease and the extent to which their skills meet the needs of cancer associations in responding to the demands that have emerged in this new context. This is a qualitative study based on data collected during semi-directed interviews, focus group sessions and on-site observations in a variety of French cancer associations. Categorical and thematic analyses were then carried out separately for each ethnographic method used. The study showed that because the commitment of survivor voluntary helpers derives from their own experience of the disease, it is inconsistent with the fulfilment of the association's collective aims, such as the search for funding or project development. These helpers nevertheless play an important role that involves a special link between the individual and the group, between the community and society. To conclude, "involved" volunteers have to reconcile their individual expectations with the association's collective aims.

    Full Text Available Factors associated with family commitment among pharmacists in the south central U.S. are explored. In 2010, a cross-sectional mailed self-administered 70 item survey of 363 active licensed pharmacists was conducted. This analysis includes only 269 (74% participants who reported being married. Outcome measures were family commitment (need for family commitment, spouse’s family commitment, work-related characteristics (work challenge, stress, workload, flexibility of work schedule, and job and career satisfaction. Married participants’ mean age was 48 (SD = 18 years; the male to female ratio was 1:1; 73% worked in retail settings and 199 (74% completed the family commitment questions. Females reported a higher need for family commitment than males (p = 0.02 but there was no significant difference in satisfaction with the commitment. Work challenge and work load were significantly associated with higher need for family commitment (p < 0.01, when controlled for age, gender, number of dependents, work status, and practice setting. Higher work challenge was associated with higher career satisfaction. Higher job related stress was associated with lower job satisfaction. High work challenge and work load may negatively impact family function since married pharmacists would need higher family commitment from their counterparts. The impact of work-family interactions on pharmacy career satisfaction should be further investigated.

    Some important vaccinations are not included in the routine childhood immunization schedule in Japan. Voluntary vaccinations are usually paid as an out-of-pocket expense. Low voluntary vaccination coverage rates and high target disease incidence are assumed to be a consequence of voluntary vaccination. Therefore, this study aimed to explore factors associated with voluntary vaccination patterns in children. We conducted an online survey of 1243 mothers from a registered survey panel who had at least one child 2 months to vaccination mainly correlated positively with annual household income and mothers' positive opinions about voluntary vaccinations, but negatively with number of children. Financial support, especially for low income households and households with more than one child, may motivate parents to vaccinate their children. Communication is also an important issue. More opportunities for education and information about voluntary vaccinations should be provided to mothers without distinguishing between voluntary and routine vaccination.

  15. Revealing ontological commitments by magic.

    Considering the appeal of different magical transformations exposes some systematic asymmetries. For example, it is more interesting to transform a vase into a rose than a rose into a vase. An experiment in which people judged how interesting they found different magic tricks showed that these asymmetries reflect the direction a transformation moves in an ontological hierarchy: transformations in the direction of animacy and intelligence are favored over the opposite. A second and third experiment demonstrated that judgments of the plausibility of machines that perform the same transformations do not show the same asymmetries, but judgments of the interestingness of such machines do. A formal argument relates this sense of interestingness to evidence for an alternative to our current physical theory, with magic tricks being a particularly pure source of such evidence. These results suggest that people's intuitions about magic tricks can reveal the ontological commitments that underlie human cognition. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Voluntary Debt Reduction Operations. Bolivia, México, and Beyond This paper studies two recent voluntary operations of debt reduction: Bolivia's buy-back and Mexico's exchange of loans for bonds. This argued that the buy-back had a cost for Bolivia and, hence, it required a political decision when comparing this option to other alternative use of its scarce foreign exchange resources. In the case of Mexico, it is shown that the operation, which can be seen as an indirect buy-back, gave this country a rate of return on the use of its reserves, between 18% and 24%. The effects of both transactions on the debtor are examined, as well as on participating and non-participating creditor banks.

  18. Mitigating greenhouse gas emissions: Voluntary reporting

    1997-10-01

    The Voluntary Reporting Program, developed pursuant to Section 1605(b) of the Energy Policy Act of 1992, permits corporations, government agencies, households, and voluntary organizations to report on their emissions of greenhouse gases, and on actions taken that have reduced or avoided emissions or sequestered carbon, to the Energy Information Administration (EIA). This, the second annual report of the Voluntary Reporting Program, describes information provided by the participating organizations on their aggregate emissions and emissions reductions, as well as their emissions reduction or avoidance projects, through 1995. This information has been compiled into a database that includes reports from 142 organizations and descriptions of 967 projects that either reduced greenhouse gas emissions or sequestered carbon. Fifty-one reporters also provided estimates of emissions, and emissions reductions achieved, for their entire organizations. The projects described actions taken to reduce emissions of carbon dioxide from energy production and use; to reduce methane and nitrous oxide emissions from energy use, waste management, and agricultural processes; to reduce emissions of halocarbons, such as CFCs and their replacements; and to increase carbon sequestration.

  19. Voluntary Green Power Market Forecast through 2015

    2010-05-01

    Various factors influence the development of the voluntary 'green' power market--the market in which consumers purchase or produce power from non-polluting, renewable energy sources. These factors include climate policies, renewable portfolio standards (RPS), renewable energy prices, consumers' interest in purchasing green power, and utilities' interest in promoting existing programs and in offering new green options. This report presents estimates of voluntary market demand for green power through 2015 that were made using historical data and three scenarios: low-growth, high-growth, and negative-policy impacts. The resulting forecast projects the total voluntary demand for renewable energy in 2015 to range from 63 million MWh annually in the low case scenario to 157 million MWh annually in the high case scenario, representing an approximately 2.5-fold difference. The negative-policy impacts scenario reflects a market size of 24 million MWh. Several key uncertainties affect the results of this forecast, including uncertainties related to growth assumptions, the impacts that policy may have on the market, the price and competitiveness of renewable generation, and the level of interest that utilities have in offering and promoting green power products.

  20. Accessing health care in a rural area: an evaluation of a voluntary medical transport scheme in the English Midlands.

    Science.gov (United States)

    Sherwood, K B; Lewis, G J

    2000-12-01

    In recent years notions of self-help and voluntarism have emerged as key elements in the delivery of services in rural England. This paper explores these themes by reference to 'Rural Wheels', a voluntary medical transport scheme in rural Northamptonshire, introduced to overcome the closure of branch surgeries and to provide access to a new medical centre. By focusing upon the organisation and operations of the scheme, the paper highlights the important role it plays in the welfare of rural residents, particularly elderly women. Yet, because effectively it is run by a small core group, the paper raises questions not just about the viability of this scheme but also about the increasing commitment of central government to the voluntary sector as a means of delivering health care to rural people.

    Full Text Available In this paper Ant Colony Search Algorithm is proposed to solve thermal unit commitment problem. Ant colony search (ACS studies are inspired from the behavior of real ant colonies that are used to solve function or combinatorial optimization problems. In the ACSA a set of cooperating agents called ants cooperates to find good solution of unit commitment problem of thermal units. The UC problem is to determine a minimal cost turn-on and turn-off schedule of a set of electrical power generating units to meet a load demand while satisfying a set of operational constraints. This proposed approach is a tested on 10 unit power system and compared to conventional methods.

  4. Non-commitment Entropy: A Noval Modalityfor Uncertainty Measurement

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Three-way decision rule is the extension of traditional two-way decision. In the real environment, a decision maker is not easy tomake choice between acceptance and rejection for the uncertainly or incomplete information. In this case, people used to choosethree-way decision for the uncertain and high risky decision with extra but necessary cost. Meanwhile some general uncertaintymeasures are proposed by generalizing Shannon's entropy. The theory of information entropy makes the uncertainty measuresmore accuracy in boundary of three-way decision. In this paper, we propose several types of non-commitment entropy by usingthe relation of the 'third' decision-non-commitment, and employ the proposed model to evaluate the significance of theattributes for classification as well.

    The World Health Organization (WHO) has reiterated its goal of reducing maternal mortality by 50% by 2000, and celebrated the 10th anniversary of its Safe Motherhood Initiative on April 7. The initiative is a coalition formed by the WHO, UNICEF, the World Bank, the UN Population Fund, and other nongovernmental organizations to encourage countries to look at the position of women in society and improve their health care. About 1600 women die every day due to complications in pregnancy and childbirth, mostly in Asia and Africa. Of all the health statistics monitored by the WHO, maternal mortality is the one with the largest discrepancy between developed and developing countries; the level of maternal mortality in the developing world is almost 18 times higher than that in the developed world and up to one third of all deaths among women of reproductive age in many developing countries are the result of complications of pregnancy or childbirth. The WHO claims that providing care from conception to delivery, including family planning and neonatal care, would cost only about $3 per woman, an important social and economic investment. China, Sri Lanka, Iran, and Cuba have had considerable success in reducing their levels of maternal mortality through a combination of commitment to the initiative and improved health care.

    2013-10-01

    Following a thorough review of the current updated Sport Commitment Model, new candidate commitment sources for possible future inclusion in the model are presented. They were derived from data obtained using the Scanlan Collaborative Interview Method. Three elite New Zealand teams participated: amateur All Black rugby players, amateur Silver Fern netball players, and professional All Black rugby players. An inductive content analysis of these players' open-ended descriptions of their sources of commitment identified four unique new candidate commitment sources: Desire to Excel, Team Tradition, Elite Team Membership, and Worthy of Team Membership. A detailed definition of each candidate source is included along with example quotes from participants. Using a mixed-methods approach, these candidate sources provide a basis for future investigations to test their viability and generalizability for possible expansion of the Sport Commitment Model.

    Voluntary cloud is a new paradigm of cloud computing. It provides an alternative selection along with some well-provisioned clouds. However, for the uncertain time span that participants share their computing resources in voluntary cloud, there are some challenging issues, i.e., fluctuation, under-capacity and low-benefit. In this paper, an architecture is first proposed based on Bittorrent protocol. In this architecture, resources could be reserved or requested from Reserved Instance Marketplace and could be accessed with a lower price in a short circle. Actually, these resources could replenish the inadequate resource pool and relieve the fluctuation and under-capacity issue in voluntary cloud. Then, the fault rate of each node is used to evaluate the uncertainty of its sharing time. By leveraging a linear prediction model, it is enabled by a distribution function which is used for evaluating the computing capacity of the system. Moreover, the cost optimization problem is investigated and a computational method is presented to solve the low-benefit issue in voluntary cloud. At last, the system performance is validated by two sets of simulations. And the experimental results show the effectiveness of our computational method for resource reservation optimization.

  19. Voluntary Nonmonetary Conservation Approaches on Private Land: A Review of Constraints, Risks, and Benefits for Raptor Nest Protection

    Science.gov (United States)

    Santangeli, Andrea; Laaksonen, Toni

    2015-02-01

    Biodiversity conservation on private land of the developed world faces several challenges. The costs of land are often high, and the attitudes of landowners towards conservation are variable. Scientists and practitioners need to scan for and adopt cost-effective solutions that allow for the long-term sustainability of conservation measures on private land. In this study, we focus on one of such possible solutions: Working with landowners to implement voluntary nonmonetary conservation. We restrict our focus to protection of raptor nests, but the ideas can be applied to other taxa as well. Through a literature review, we show that a voluntary nonmonetary approach for protecting raptor nests has been so far largely neglected and/or rarely reported in the scientific literature. However, results of a questionnaire sent to BirdLife partners across Europe indicate that this approach is more widely used than it appears from the literature. We show that voluntary nonmonetary approaches may represent useful tools to protect raptor nests on private land. We provide a workflow for implementation of such an approach in raptor nest protection, highlighting benefits, potential risks, and constraints in the application of the strategy. We suggest that a voluntary nonmonetary approach may have great potential for cost-effective conservation, but the risks it may entail should be carefully assessed in each case. There is an urgent need to consider and evaluate novel approaches, such as the one described here, which may constitute missed opportunities for cost-effective conservation.

  20. Optimal Deadline Scheduling with Commitment

    CERN Document Server

    Chen, Shiyao; He, Ting

    2011-01-01

    We consider an online preemptive scheduling problem where jobs with deadlines arrive sporadically. A commitment requirement is imposed such that the scheduler has to either accept or decline a job immediately upon arrival. The scheduler's decision to accept an arriving job constitutes a contract with the customer; if the accepted job is not completed by its deadline as promised, the scheduler loses the value of the corresponding job and has to pay an additional penalty depending on the amount of unfinished workload. The objective of the online scheduler is to maximize the overall profit, i.e., the total value of the admitted jobs completed before their deadlines less the penalty paid for the admitted jobs that miss their deadlines. We show that the maximum competitive ratio is $3-2\\sqrt{2}$ and propose a simple online algorithm to achieve this competitive ratio. The optimal scheduling includes a threshold admission and a greedy scheduling policies. The proposed algorithm has direct applications to the chargin...

  1. Prosodic form and parsing commitments.

    Science.gov (United States)

    Watt, S M; Murray, W S

    1996-03-01

    This paper examines the question of whether there are effects of prosody on the syntactic parsing of temporarily ambiguous sentences containing complement verbs. It reports the results of five experiments employing cross-modal response tasks where the visually presented target word was either an ¿appropriate' or an ¿inappropriate' continuation in terms of the prosodic form of the preceeding auditory sentence fragment. Two experiments employing cross-modal naming only showed indications of sensitivity to syntactic and appropriateness manipulations when coupled with a simultaneous appropriateness judgment task. In contrast, the experiments employing cross-modal lexical decision showed greater sensitivity to syntactic and appropriateness effects. However, while the results from these studies replicated our earlier auditory parsing results and provided support for the suggestion that there are differences in visual and auditory parsing processes and for a ¿constituent-based, ' ¿minimal commitment' type auditory parser, none of the studies demonstrated an effect of prosodic form on the parsing process.

  2. Grief functions as an honest indicator of commitment.

    Winegard, Bo M; Reynolds, Tania; Baumeister, Roy F; Winegard, Benjamin; Maner, Jon K

    2014-05-01

    Grief is a puzzling phenomenon. It is often costly and prolonged, potentially increasing mortality rates, drug abuse, withdrawal from social life, and susceptibility to illness. These costs cannot be repaid by the deceased and therefore might appear wasted. In the following article, we propose a possible solution. Using the principles of social selection theory, we argue that an important selective pressure behind the human grief response was the social decisions of other humans. We combine this with insights from signaling theory, noting that grief shares many properties with other hard-to-fake social signals. We therefore contend that grief was shaped by selective forces to function as a hard-to-fake signal of (a) a person's propensity to form strong, non-utilitarian bonds and (b) a person's current level of commitment to a group or cause. This theory explains many of the costly symptoms of grief and provides a progressive framework for future research.

    Gabriele, Jeanne M; Gill, Diane L; Adams, Claire E

    2011-03-01

    Several theories and models have been proposed to explain decisions in changing and adopting behavior but few address the intricacies of behavioral maintenance. The current study assesses the utility of the Investment Model, which identifies satisfaction, investments, and involvement alternatives as predictors of commitment and continued behavior, in predicting physical activity behavior. Participants (N = 267) completed questionnaires about physical activity and commitment. Structural equation modeling assessed relationships among 2 types of exercise commitment (want to or enthusiastic commitment, have to or obligatory commitment), 3 commitment determinants (satisfaction, investments, and alternatives), and physical activity (minutes of physical activity, stage of behavior change). Want to commitment, but not have to commitment, was related to stage of exercise behavior change and time spent in physical activity. Satisfaction and investments were positively related to want to commitment; whereas, satisfaction, investments, and alternatives were positively related to have to commitment. The model explained 68% and 23% of the variance in time spent in physical activity and stage of behavior change, respectively. This study provides support for the application of the Investment Model to physical activity and suggests that want to commitment may be important for explaining and predicting sustained physical activity behavior.

  4. Voluntary vaccination strategy and the spread of sexually transmitted diseases.

    Xu, Fei; Cressman, Ross

    2016-04-01

    In this work, we investigate the spread and control of sexually transmitted diseases when a game-theory based vaccination strategy is involved. An individual's decision on vaccination uptake may follow a cost-benefit analysis since the individual obtains immunity against the disease from the vaccination and, at the same time, may have some perceived side effects. Evolutionary game theory is integrated into the epidemic model to reveal the relationship between individuals' voluntary decisions on vaccination uptake and the spread and control of such diseases. We show that decreasing the perceived cost of taking vaccine or increasing the payoff from social obligation is beneficial to controlling the disease. It is also shown how the "degree of rationality" of males and females affects the disease spread through the net payoff of the game. In particular, individual awareness of the consequences of the disease on the infectives also contributes to slowing down the disease spread. By analyzing an asymmetric version of our evolutionary game, it is shown that the disease is better controlled when individuals are more sensitive to fitness differences when net payoff is positive than when it is negative.

  5. The parallel programming of voluntary and reflexive saccades.

    Walker, Robin; McSorley, Eugene

    2006-06-01

    A novel two-step paradigm was used to investigate the parallel programming of consecutive, stimulus-elicited ('reflexive') and endogenous ('voluntary') saccades. The mean latency of voluntary saccades, made following the first reflexive saccades in two-step conditions, was significantly reduced compared to that of voluntary saccades made in the single-step control trials. The latency of the first reflexive saccades was modulated by the requirement to make a second saccade: first saccade latency increased when a second voluntary saccade was required in the opposite direction to the first saccade, and decreased when a second saccade was required in the same direction as the first reflexive saccade. A second experiment confirmed the basic effect and also showed that a second reflexive saccade may be programmed in parallel with a first voluntary saccade. The results support the view that voluntary and reflexive saccades can be programmed in parallel on a common motor map.

  6. Education: Commodity, Come-On, or Commitment?

    Science.gov (United States)

    Moore, John W.

    2000-07-01

    July 4, and the glass art shown on pages 812-816, remind us that freedom is fragile. Through their governments, citizens of democracies have traditionally made strong commitments to education on grounds that without it individuals would not be able to act responsibly and to make wise decisions in voting booths and public meetings. All citizens have a stake in everyone's education, because a better-educated citizenry benefits all of society. In this country such a commitment has produced a system of public schools and public universities that offers opportunities to many who otherwise could not afford a level of education commensurate with their talents. But there are signs that this commitment to public education is flagging. Many students, teachers, and administrators view education as merely a way to enhance personal prosperity. How often have you heard the statistic that a college education pays for itself through increased earning power, even if it costs $20,000-30,000 per year? Investing in education pays off just as investing in the stock market does, provided you wait long enough. Attending a better school gets you a better job and a better income. In other words, a certified level of education is a commodity-something that is useful and can be turned to commercial advantage. Viewing education as a commodity has several consequences. First, if education is a means to better employment rather than better citizenship, why should anyone pay for it other than the person who benefits? Why should I pay taxes to help someone else get a better job when I could be spending the money for my own benefit? Education as a commodity makes such attitudes reasonable, though not commendable, and the result is lessened support for public education. Second, those who supply education as an economic good should be rewarded, and those who are much better at educating should be rewarded much more. Hence the fear of Arthur Levine, president of Teachers College, Columbia University

  14. Voluntary self-touch increases body ownership

    2015-10-01

    Full Text Available Experimental manipulations of body ownership have indicated that multisensory integration is central to forming bodily self-representation. Voluntary self-touch is a unique multisensory situation involving corresponding motor, tactile and proprioceptive signals. Yet, even though self-touch is frequent in everyday life, its contribution to the formation of body ownership is not well understood. Here we investigated the role of voluntary self-touch in body ownership using a novel adaptation of the rubber hand illusion (RHI, in which a robotic system and virtual reality allowed participants self-touch of real and virtual hands. In the first experiment, active and passive self-touch were applied in the absence of visual feedback. In the second experiment, we tested the role of visual feedback in this bodily illusion. Finally, in the third experiment, we compared active and passive self-touch to the classical RHI in which the touch is administered by the experimenter. We hypothesized that active self-touch would increase ownership over the virtual hand through the addition of motor signals strengthening the bodily illusion. The results indicated that active self-touch elicited stronger illusory ownership compared to passive self-touch and sensory only stimulation, and indicate an important role of active self-touch in the formation of bodily self.

  16. Commitment and Trust in Young Adult Friendships

    Directory of Open Access Journals (Sweden)

    Jennifer Wieselquist

    2007-12-01

    Full Text Available Given the importance of maintaining mutuality in interdependent relationships, the goal of the present research was to determine if interpersonal trust serves as a gauge of partners’ commitment within young adults’ close friendships. It was hypothesized that individuals trust their friends to the degree that their friends are committed to their relationship, and that individuals’ perceptions of their friends’ commitment mediates this association. A correlational design was employed and measures were obtained from both members of 60 same-sex friendship dyads. A multilevel modeling approach was used to perform a mediational analysis of model variables; the hypotheses were confirmed. Furthermore, it was revealed that friends demonstrate a moderate degree of mutual commitment in their relationships. Potential avenues for future research regarding the development and consequences of trust in close friendships are discussed.

  18. Voluntary Participation in Regional Fisheries Management Council Meetings

    Directory of Open Access Journals (Sweden)

    James Wilson

    2010-09-01

    Full Text Available Insufficient and unrepresentative participation in voluntary public hearings and policy discussions has been problematic since Aristotle's time. In fisheries, research has shown that involvement is dominated by financially resourceful and extreme-opinion stakeholders and tends to advantage groups that have a lower cost of attendance. Stakeholders may exhibit only one or all of these traits but can be still similarly advantaged. The opposites of these traits tend to characterize the disadvantaged, such as the middle-ground opinions, the less wealthy or organized, and the more remote stakeholders. Remoteness or distance is the most straightforward and objective of these characteristics to measure. We analyzed the New England Fishery Management Council's sign-in sheets for 2003–2006, estimating participants' travel distance and associations with the groundfish, scallop, and herring industries. We also evaluated the representativeness of participation by comparing attendance to landings and permit distributions. The distance analysis showed a significant correlation between attendance levels and costs via travel distance. These results suggest a potential bias toward those stakeholders residing closer to meeting locations, possibly disadvantaging parties who are further and must incur higher costs. However, few significant differences were found between the actual fishing industry and attendee distributions, suggesting that the geographical distribution of the meeting attendees is statistically similar to that of the larger fishery. The interpretation of these results must take into consideration the limited time span of the analysis, as policy changes may have altered the industry make-up and location prior to our study. Furthermore, the limited geographical input of stakeholders may lend bias to the Council's perception of ecological and social conditions throughout the spatial range of the fishery. These factors should be further considered in

    With recent advances of quantum computation, new threats have closed in upon to the classical public key cryptosystems. In order to build more secure bit commitment schemes, this paper gave a survey of the new coming braid-based cryptography and then brought forward the first braid-based bit commitment protocol. The security proof manifests that the proposed protocol is computationally binding and information-theoretically hiding.Furthermore, the proposed protocol is also invulnerable to currently known quantum attacks.

    Full Text Available This paper presents a new approach to solve short-term unit commitment problem (UCP using Neural Based Tabu Search (NBTS with cooling and banking constraints. The objective of this paper is to find the generation scheduling such that the total operating cost can be minimized, when subjected to a variety of constraints. This also means that it is desirable to find the optimal generating unit commitment in the power system for next H hours. A 7-unit utility power system in India demonstrates the effectiveness of the proposed approach; extensive studies have also been performed for different IEEE test systems consist of 10, 26 and 34 units. Numerical results are shown to compare the superiority of the cost solutions obtained using the Tabu Search (TS method, Dynamic Programming (DP and Lagrangian Relaxation (LR methods in reaching proper unit commitment.

    Full Text Available I compare the suicide deaths of Heinrich von Kleist and Jean Améry (Hans Mayer. I discuss the issue of suicide, considering it as a category of the German language and distinguish the difference between the terms ‘Selbstmord’ [self-annihilation] and ‘Freitod’ [self-inflicted death, voluntary death]. By comparing the two suicides committed on the two verges of modernity (the beginning of 19th century in Berlin and 20th century after Auschwitz, I try to describe them as an experience of the imagination (in the words of Stefan Chwin and as a specific act of creation: a choice of a voluntary death. Suicide, comprehended as a confirmation of our existential freedom, was a deviation from what was considered the norm in Prussia in 1811 and did not seem possible as anything else than an act of despair, when committed by a death camp survivor. However, Heinrich von Kleist and Jean Améry have set a precedent in the existing cultural and historical paradigms of suicide.

    1988-06-01

    Britain's High Court recently overruled two decisions of the Mental Health Act Commission that denied certification of a voluntary experimental drug treatment to a mental patient, holding that the standard for informed consent is determined not by the subjective judgment of the commissioners but by whether the patient knows the nature and likely effects of treatment and that its use in his case is a novel one. The background facts of the case involving a 27-year-old pedophile receiving goserelin implantations to reduce testosterone levels are presented and the issues of jurisdiction under the Mental Health Act 1983 and the commissioners' duty to act fairly and to consider the likely benefits of treatment are discussed.

  18. Lateral asymmetry of voluntary attention orienting

    B.A. Castro-Barros

    2010-08-01

    Full Text Available We recently demonstrated that automatic attention favors the right side of space and, in the present study, we investigated whether voluntary attention also favors this side. Six reaction time experiments were conducted. In each experiment, 12 new 18-25-year-old male right-handed individuals were tested. In Experiments 1, 2, 3 (a, b and 4 (a, b, tasks with increasing attentional demands were used. In Experiments 1, 2, 3a, and 4a, attention was oriented to one or both sides by means of a central spatially informative visual cue. A left or right side visual target appeared 100, 300, or 500 ms later. Attentional effects were observed in the four experiments. In Experiments 2, 3a and 4a, these effects were greater when the cue indicated the right side than when it indicated the left side (respectively: 16 ± 10 and 44 ± 6 ms, P = 0.015, for stimulus onset asynchrony of 500 ms in Experiment 2; 38 ± 10 and 70 ± 7 ms, P = 0.011, for Experiment 3a, and 23 ± 11 and 61 ± 10 ms, P = 0.009, for Experiment 4a. In Experiments 3b and 4b, the central cue pointed to both sides and was said to be non-relevant for task performance. In these experiments right and left reaction times did not differ. The most conservative interpretation of the present findings is that voluntary attention orienting favors the right side of space, particularly when a difficult task has to be performed.

    Mace, John H; Clevinger, Amanda M

    2013-01-01

    The goal of this study was to show that voluntary autobiographical memories could be primed by the prior activation of autobiographical memories. Three experiments demonstrated voluntary memory priming with three different approaches. In Experiment 1 primed participants were asked to recall memories from their elementary school years. In a subsequent memory task primed participants were asked to recall memories from any time period, and they produced significantly more memories from their elementary school years than unprimed participants. In Experiment 2 primed participants were asked to recall what they were doing when they had heard various news events occurring between 1998 and 2005. Subsequently these participants produced significantly more memories from this time period than unprimed participants. In Experiment 3 primed participants were asked to recall memories from their teenage years. Subsequently these participants were able to recall more memories from ages 13-15 than unprimed participants, where both had only 1 second to produce a memory. We argue that the results support the notion that episodic memories can activate one another and that some of them are organised according to lifetime periods. We further argue that the results have implications for the reminiscence bump and voluntary recall of the past.

  1. Ethical challenges in voluntary blood donation in Kerala, India.

    Science.gov (United States)

    Choudhury, L P; Tetali, S

    2007-03-01

    The National Blood Policy in India relies heavily on voluntary blood donors, as they are usually assumed to be associated with low levels of transfusion-transmitted infections (TTIs). In India, it is mandatory to test every unit of blood collected for hepatitis B, hepatitis C, HIV/AIDS, syphilis and malaria. Donors come to the blood bank with altruistic intentions. If donors test positive to any of the five infections, their blood is discarded. Although the blood policy advocates disclosure of TTI status, donors are not, in practice, informed about their results. The onus is on the donor to contact the blood bank. Out of approximately 16 000 donations in the past 2 years, 438 tested positive for TTI, including 107 for HIV. Only 20% of the donors contacted the blood bank; none of them were HIV positive. Disclosure by blood banks of TTI status by telephone or mail has resulted in serious consequences for some donors. Health providers face an ethical dilemma, in the absence of proper mechanisms in place for disclosure of test results, regarding notification to donors who may test positive but remain ignorant of their TTI status. Given the high cost of neglecting to notify infected donors, the authors strongly recommend the use of rapid tests before collecting blood, instead of the current practice, which takes 3 h to obtain results, and disclosure of results directly to the donor by a counsellor, to avoid dropouts and to ensure confidentiality.

  2. A model of voluntary turnover among hospital CEOs.

    Weil, P A; Kimball, P A

    1995-01-01

    This study examines factors contributing to hospital CEOs' voluntary decisions to leave their positions in 1990. Using a longitudinal design, we contrast 49 leavers with 1,362 stayers. We view turnover as influenced by both "push" factors that promote leaving (dissatisfaction with the position) and "hump" factors that need to be overcome (the cost of job change). Push factors giving rise to dissatisfaction include lower compensation, the predecessor's termination, and value incongruity between the CEO and the hospital. Testing the impact of key variables from Fiedler's contingency theory of leadership, we show that task-oriented leaders are relatively less satisfied when compared with relationship-oriented leaders. CEOs also express less satisfaction in low-situational control settings, a measure heavily influenced by perceived inadequate support from medical staff and subordinates. "Hump" factors that deterred leaving included family-related obstacles such as spouse's work or children's school, features mentioned most often by younger CEOs. The study suggests that boards should structure competitively paid positions with opportunities to generate support from the medical staff and subordinates. Recruiters for CEO positions are apprised of the importance of nonwork features in CEOs' willingness to consider new positions.

    2016-03-01

    The emergence of new markets for forest ecosystem services can be a compelling opportunity for market diversification for private forest landowners, while increasing the provision of public goods from private lands. However, there is limited information available on the willingness-to-pay (WTP) for specific forest ecosystem services, particularly across different ecosystem market mechanisms. We utilize survey data from Oregon and Washington households to compare marginal WTP for forest ecosystem services and the total WTP for cost-effective bundles of forest ecosystem services obtained from a typical Pacific Northwest forest across two value elicitation formats representing two different ecosystem market mechanisms: an incentive-compatible choice experiment involving mandatory tax payments and a hypothetical private provision scenario modeled as eliciting contributions to the preferred forest management alternative via a provision point mechanism with a refund. A representative household's total WTP for the average forest management program was estimated at 217.59 per household/year under a mandatory tax mechanism and 160.44 per household/per year under a voluntary, crowdfunding-style, contribution mechanism; however, these estimates are not statistically different. Marginal WTP estimates were assessed for particular forest ecosystem service attributes including water quality, carbon storage, mature forest habitat, and public recreational access. This study finds that survey respondents place significant economic value on forest ecosystem services in both elicitation formats and that the distributions of the marginal WTP are not statistically significantly different.

  8. SEA screening of voluntary climate change plans: A story of non-compliant discretion

    Energy Technology Data Exchange (ETDEWEB)

    Kørnøv, Lone, E-mail: lonek@plan.aau.dk; Wejs, Anja

    2013-07-15

    Screening within Strategic Environmental Assessment (SEA) is the first critical stage involving considerations on whether an assessment is carried out or not. Although legislation and guidance offer practitioners a legal and logical approach to the screening process, it is inevitable that discretionary judgement takes place and will impact on the screening decision. This article examines the results of discretion involved in screening of climate change plans (CCPs) in a Danish context. These years voluntary CCPs are developed as a response to the global and local emergence of both mitigation and adaptation, and the voluntary commitment by the local authorities is an indication of an emerging norm of climate change as an important issue. This article takes its point of departure in the observation that SEA is not undertaken for these voluntary CCPs. The critical analysis of this phenomenon rests upon a documentary study of Danish CCPs, interviews with a lawyer and ministerial key person and informal discussions between researchers, practitioners and lawyers on whether climate change plans are covered by SEA legislation and underlying reasons for the present practice. Based on a critical analysis of mandatory SEA and/or obligation to screen CCPs according to significance criteria, the authors find that 18 out of the 48 CCPs are mandatory to SEA and 9 would require a screening of significance and thereby potentially be followed by a SEA. In practice only one plan was screened and one was environmentally assessed. The legal, democratic and environmental consequences of this SEA practice are critically discussed. Hereunder is the missed opportunity to use the broad environmental scope of SEA to avoid a narrow focus on energy and CO{sub 2} in CCPs, and the question whether this practice in Denmark complies with the EU Directive. -- Highlights: ► It is inevitable that discretionary judgement takes place and will impact on the screening decision. ► The article hereby

  14. Voluntary exercise at the expense of reproductive success in Djungarian hamsters ( Phodopus sungorus)

    Energy demands of gestation and lactation represent a severe challenge for small mammals. Therefore, additional energetic burdens may compromise successful breeding. In small rodents, food restriction, cold exposure (also in combination) and wheel running to obtain food have been shown to diminish reproductive outcome. Although exhibited responses such as lower incidence of pregnancy, extended lactation periods and maternal infanticide were species dependent, their common function is to adjust energetic costs to the metabolic state reflecting the trade-off between maternal investment and self-maintenance. In the present study, we sought to examine whether voluntary exercise affects reproduction in Djungarian hamsters ( Phodopus sungorus), which are known for their high motivation to run in a wheel. Voluntary exercise resulted in two different effects on reproduction; in addition to increased infanticide and cannibalism, which was evident across all experiments, the results of one experiment provided evidence that free access to a running wheel may prevent successful pregnancy. It seems likely that the impact of voluntary wheel running on reproduction was associated with a reduction of internal energy resources evoked by extensive exercise. Since the hamsters were neither food-restricted nor forced to run in the present study, an energetic deficit as reason for infanticide in exercising dams would emphasise the particularly high motivation to run in a wheel.

    Full Text Available Background: Voluntary counseling and testing (VCT is an important preventive strategy in the control of HIV/AIDS and Long distance truck drivers (LDTD have been identified as an important group in the transmission of HIV/AIDS. This study aims to assess knowledge and perception of Nigerian long distance truck drivers on HIV/AIDS, voluntary counseling and testing and their willingness to undergo HIV screening. Materials and Methods: One hundred and ninety seven LDTD in Enugu, Nigeria were surveyed using pre tested structured questionnaires. Results: Awareness of HIV/AIDS was high (94.9% amongst the drivers and the media was their commonest source of information. Similarly the awareness of VCT was high (94.4%. One hundred and eight (54.8% respondents were willing to undergo HIV screening test if offered freely and 86 (43.7% others have previously been screened. Educational status was a significant determinant of willingness to undergo HIV screening p<0.05. The reasons for screening were mainly doctors′ recommendation (19.3% and voluntary self screening (18.8%. The commonest reasons for not wanting to undergo screening were the feeling of not being at risk (27.9%, fear of a positive result (10.2% and cost of screening test (9.6%. Conclusion: There is a critical need to improve HIV screening participation amongst Long distance drivers in Nigeria.

    Voluntary vaccination reflects how individuals weigh the risk of infection and the cost of vaccination against the spread of vaccine-preventable diseases, such as smallpox and measles. In a homogeneously mixing population, the infection risk of an individual depends largely on the proportion of vaccinated individuals due to the effects of herd immunity. While in a structured population, the infection risk can also be affected by the structure of individuals' social network. In this paper, we focus on studying individuals' self-organizing behaviors under the circumstance of voluntary vaccination in different types of social networks. Specifically, we assume that each individual together with his/her neighbors forms a local well-mixed environment, where individuals meet equally often as long as they have a common neighbor. We carry out simulations on four types of locally-mixed social networks to investigate the network effects on voluntary vaccination. Furthermore, we also evaluate individuals' vaccinating decisions through interacting with their "neighbors of neighbors". The results and findings of this paper provide a new perspective for vaccination policy-making by taking into consideration human responses in complex social networks.

    The general purpose of this work is to analyze the overlap between organizational identification and commitment. Specifically, our study focuses on the analysis of the differences and similarities between sense of belonging (a dimension of organizational identification) and affective commitment (a dimension of organizational commitment). In order to do this, we analyzed their discriminant validity and raised their relationship with variables that previous research had showed like precedent and subsequent variables of them: value congruence, perceived support, organizational citizenship behavior, and intention to continue in the organization. A total of 292 people at one organization completed surveys measuring the variables previously described. The results showed that sense of belonging and affective commitment are different concepts and they have different relationships with relation to precedent and subsequent variables. Affective commitment seems to be more useful than sense of belonging to predict organizational citizenship behavior aimed at the organization and intention to continue. Some practical implications are described.

    The Columbia River has been called the “crown jewel” of the Pacific Northwest. There is no question it is among the region’s greatest assets — supplying low-cost clean hydropower, making deserts bloom thanks to irrigation and providing navigation, recreation and a home for many species of fish and wildlife. The Bonneville Power Administration is proud to be a steward of this great resource. Our mission is to serve the people and environment of the Pacific Northwest. We sell wholesale power from Grand Coulee Dam and 30 other Northwest federal dams to Northwest utilities, including public utility districts, rural electric cooperatives and municipal utility departments, as well as investor-owned utilities. We operate three-fourths of the region’s high voltage transmission system that delivers that power. But, as a federal agency, we are not just a power marketer. We have public responsibilities that include, among many, promoting energy efficiency, facilitating development of renewable power, protecting fish and wildlife affected by hydro development, honoring treaty obligations to tribes and promoting a reliable energy future through collaboration and partnerships. This document describes our responsibilities to citizens in the Pacific Northwest.

    We have measured the cardiovascular responses during voluntary and nonvoluntary (electrically induced) one-leg static exercise in humans. Eight normal subjects were studied at rest and during 5 min of static leg extension at 20% of maximal voluntary contraction performed voluntarily and nonvoluntarily in random order. Heart rate (HR), mean arterial pressure (MAP), and cardiac output (CO) were determined, and peripheral vascular resistance (PVR) and stroke volume (SV) were calculated. HR increased from approximately 65 +/- 3 beats/min at rest to 80 +/- 4 and 78 +/- 6 beats/min (P voluntary and nonvoluntary contractions, respectively. CO increased from 5.1 +/- 0.7 to 6.0 +/- 0.8 and 6.2 +/- 0.8 l/min (P voluntary and nonvoluntary contractions, respectively. PVR and SV did not change significantly during voluntary or nonvoluntary contractions. Thus the cardiovascular responses were not different between voluntary and electrically induced contractions. These results suggest that the increases in CO, HR, SV, MAP, and PVR during 5 min of static contractions can be elicited without any contribution from a central neural mechanism (central command). However, central command could still have an important role during voluntary static exercise.

    Today's investment decisions in key sectors such as energy, forestry or transport have significant impacts on the levels of greenhouse gas (GHG) emissions over the coming decades. Given the economic and environmental long-term implications of capital investment and retirement, a climate mitigation regime should aim to encourage capital investment in climate-friendly technologies. Many factors affect technology choice and the timing of investment, including investor expectations about future prices and policies. Recent international discussions have focused on the importance of providing more certainty about future climate policy stringency. The design of commitment periods can play a role in creating this environment. This paper assesses how the length of commitment periods influences policy uncertainty and investment decisions. In particular, the paper analyses the relationship between commitment period length and near term investment decisions in climate friendly technology.

    The assigned topic, "Contractor and Government: Teamwork and Commitment," is a subject about vitally interested. The successes of the U.S. space program were built on such teamwork and commitment. It seems only a short time ago that man's role in space was an unknown quantity. In rapid succession, however, the flights of Shepard, Glenn, and Armstrong demonstrated man's capability to live and travel in space. Consequently, we no longer live with the same awe of space. The success of these joint industry-NASA efforts in achieving our Nation's space goals testifies to the validity of our team's past commitment, management expertise, communications techniques, and teamwork over a period of 25 years. Today, however, We are at the beginning of a new era in space.

    One of the main concept objectives of smart cities is to create a quality living environment that is long-term sustainable and economically justified. In that context, modern cities are aware of the exposure to various forms of physical and non-physical pollution that needs to be remediated, eliminated or reduced. To achieve that it is necessary to quality determine the sources and reasons of each pollution. The most prominent examples of physical pollution that affects the quality of life of citizens in cities are light and noise pollution. Noise pollution or noise, is mostly the consequence of road and rail traffic in cities and it directly affects the health of citizens. Traffic control, reduction of peak congestion, dispersion and traffic redirection or building protective barriers, are ways that cities use to reduce the amount of noise or its effects. To make these measures efficient it is necessary to obtain the information related to the level of noise in certain areas, streets, cities. To achieve this, smart cities use noise mapping.

    Both voluntary and involuntary movements activate sensors in the muscles, skin, tendon and joints. As limb movement can result from a mixture of spinal reflexes and voluntary motor commands, the cortical centres underlying conscious proprioception might either aggregate or separate the sensory inputs generated by voluntary movements from those generated by involuntary movements such as spinal reflexes. We addressed whether healthy volunteers could perceive the contribution of a spinal reflex during movements that combined both reflexive and voluntary contributions. Volunteers reported the reflexive contribution in leg movements that were partly driven by the knee-jerk reflex induced by a patellar tendon tap and partly by voluntary motor control. In one condition, participants were instructed to kick back in response to a tendon tap. The results were compared to reflexes in a resting baseline condition without voluntary movement. In a further condition, participants were instructed to kick forwards after a tap. Volunteers reported the perceived reflex contribution by repositioning the leg to the perceived maximum displacement to which the reflex moved the leg after each tendon tap. In the resting baseline condition, the reflex was accurately perceived. We found a near-unity slope of linear regressions of perceived on actual reflexive displacement. Both the slope value and the quality of regression fit in individual volunteers were significantly reduced when volunteers were instructed to generate voluntary backward kicks as soon as they detected the tap. In the kick forward condition, kinematic analysis showed continuity of reflex and voluntary movements, but the reflex contribution could be estimated from electromyography (EMG) recording on each trial. Again, participants' judgements of reflexes showed a poor relation to reflex EMG, in contrast to the baseline condition. In sum, we show that reflexes can be accurately perceived from afferent information. However

    In recent years, both compliance and voluntary markets have emerged to help support the development of renewable energy resources. Both of these markets are growing rapidly and today about half of U.S. states have RPS policies in place, with a number of these policies adopted in the last several years. In addition, many states have recently increased the stringency of their RPS policies. This paper examines key market interaction issues between compliance and voluntary renewable energy markets. It provides an overview of both the compliance and voluntary markets, addressing each market's history, purpose, size, scope, and benefits while addressing issues, including double counting.

    Full Text Available 'What motivates suicide attackers remains an open question. From an evolutionary perspective, commitment to suicide missions is puzzling since such behavior is fitness reducing. We model suicide terrorism by drawing on two fundamental human motivations: altruism and selfishness. Martyrdom can be viewed as altruistic- benefiting group members at a cost to oneself, as well as selfish- ideological belief in a profitable afterlife. Our simulations identify that some degree of both behaviors are essential in order to facilitate a commitment to sacrifice. Thus, manipulations of ideology and altruism can tip the threshold and set the agents on the path of martyrdom. '

The national intelligence is measured by nation's IQ scores. The findings based on a sample of 152 nations provide strong evidence that intelligence has statistically significant impact on ratification of international environmental agreements, and the countries with IQ 10-points above global average are 23% more likely to sign multilateral environmental agreements than others. The findings also demonstrate that it is the combination of high-level of intelligence of nations and democracy, that likely result in international environmental commitments.

    Full Text Available Nowadays, when the welfare state is a responsibility of the entire society, organizations in the private sector assume co-responsibility for social issues. They are also pressured by the challenges presented by technological advances and the globalization , involving new parameters and requirements for quality. In this context, the concept of Corporate Social Responsibility (RSC emerges as an option for solutions to the issues related to the company and the whole community. Among the actions of the RSC is the Corporate Volunteering-program, which aims to promote / encourage employes to do voluntary work. A central issue when talking about volunteering is the withdrawal of these (SILVA and FEITOSA, 2002; TEODÓSIO, 1999 and, in accordance with the Community Solidarity (1997, one of the possible causes for the withdrawal is the lack of clarity as to the motives and expectations that lead the person to volunteer themselves. This study uses qualitative research and triangulation of feedback from volunteers, coordinators of volunteers and social organizations, to present a framework from which it is possible to analyze the various motivations for the volunteer work. Key words: Corporate Volunteering program. Volunteering. Corporate social responsibility.

    2011-01-01

    This paper presents a series of findings generated during a larger study which aimed to develop a theoretical understanding of the reasons why nursing students voluntarily leave pre-registration nursing programmes. In this study, significant incongruence was found to exist between student expectations of pre-registration nursing programmes and the reality of these programmes following entry. The resulting dissonance was identified as an important factor in student decisions to voluntarily withdraw. A single case study design was selected to explore the causes of voluntary attrition in nursing students within a School of Nursing and Midwifery. The study population was obtained through purposeful sampling and consisted of 15 students who had previously voluntarily withdrawn from pre-registration nursing programmes. A semi-structured interview method was used to collect data from study participants. The interview schedule developed for use in the study reflected the key components of the conceptual model of higher education (HE) student attrition (Tinto, 1975, 1987, 1993). All interviews were tape recorded to facilitate later transcription. The Cyclical or Interactive Model of Qualitative Research (Miles and Huberman, 1994) was used to analyse data collected from study participants. This paper describes the unrealistic range of expectations which nursing students have of nursing, the information sources and experiences which inform student expectations and how ambiguous expectations contributed to voluntarily attrition.

    2014-01-30

    The legal status of service users admitted to psychiatric wards is not synonymous with the level of coercion that they can perceive during the admission. This study aimed to identify and describe the proportion of individuals who were admitted voluntarily but experienced levels of perceived coercion comparable to those admitted involuntarily. Individuals admitted voluntarily and involuntarily to three psychiatric hospitals were interviewed using the MacArthur Admission Experience Interview and the Structured Clinical Interview for DSM-IV diagnoses. One hundered sixty-one individuals were interviewed and 22% of the voluntarily admitted service users had levels of perceived coercion similar to that of the majority of involuntarily admitted service users. Voluntarily admitted service users who experienced high levels of perceived coercion were more likely to have more severe psychotic symptoms, have experienced more negative pressures and less procedural justices on admission. Individuals brought to hospital under mental health legislation but who subsequently agreed to be admitted voluntarily and those treated on a secure ward also reported higher levels of perceived coercion. It needs to be ensured that if any service user, whether voluntary or involuntary, experiences treatment pressures or coercion that there is sufficient oversight of the practice, to ensure that individual\\'s rights are respected.

    Voluntary turnover in nursing can lead to nursing shortages that affect both individuals and the entire hospital unit. We investigated the relationship between group- and individual-level variables by examining the association of nurses' job satisfaction and team commitment at the individual level, and nurse-physician collaboration at the group level, with individuals' intention to leave the unit at the individual level. A self-report questionnaire was administered to 1,024 nurses on 72 units in 3 Italian hospitals. At the individual level, affective commitment partially mediated the relationship between job satisfaction and nursing turnover intention. Moreover, a cross-level interaction was found. Nurses with high levels of job satisfaction showed high levels of identification with their team, and this relationship was stronger when the group perception of nurse-physician collaboration was high. Results suggested that managerial strategies to promote nurse-physician collaboration may be important to increase nurses' affective commitment to the team. At the individual level, job satisfaction and team affective commitment are important factors for retaining staff, and at the group level, good work collaboration with physicians is instrumental in developing nurses' affective identification with the team. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    The aim of this work was to evaluate the goodness of fit of a signal issued of the respiratory inductance plethysmography (RIP) derivative to the airflow signal during rest, voluntary hyperventilation, and recovery. RIP derivative signal was filtered with an adjusted filter based on each subject airflow signal (pneumotachography). For each subject and for each condition (rest, voluntary hyperventilation, and recovery) comparisons were performed between the airflow signal and the RIP derivative signal filtered with an adjusted filter obtained either on rest signal or on the studied part of the signals (voluntary hyperventilation or recovery). Results show that the goodness of fit was : (1) higher than 90% at almost all comparisons (122 on 132), (2) not improved by applying an adjusted filter obtained on the studied part of the signals. These results suggest that RIP could be used for studying breathing during voluntary hyperventilation and recovery using adjusted filters obtained from comparison to airflow signal at rest.

    2011-05-01

    Environmental planners and managers face unique challenges understanding and documenting the effectiveness of programs that rely on voluntary actions by private landowners. Programs, such as those aimed at reducing nonpoint source pollution or improving habitat, intend to reach those goals by persuading landowners to adopt behaviors and management practices consistent with environmental restoration and protection. Our purpose with this paper is to identify barriers for improving voluntary environmental management programs and ways to overcome them. We first draw upon insights regarding data, learning, and adaptation from the adaptive management and performance management literatures, describing three key issues: overcoming information constraints, structural limitations, and organizational culture. Although these lessons are applicable to a variety of voluntary environmental management programs, we then present the issues in the context of on-going research for nonpoint source water quality pollution. We end the discussion by highlighting important elements for advancing voluntary program efforts.

  3. Validating Teacher Commitment Scale Using a Malaysian Sample

    2014-05-01

    Full Text Available This study attempts to validate an integrative Teacher Commitment scale using rigorous scale validation procedures. An adapted questionnaire with 17 items was administered to 600 primary school teachers in Penang, Malaysia. Data were analyzed using exploratory factor analysis (EFA and confirmatory factor analysis (CFA with SPSS 19.0 and AMOS 19.0, respectively. The results support Teacher Commitment as a multidimensional construct with its four underlying dimensions: Commitment to Student, Commitment to Teaching, Commitment to School, and Commitment to Profession. A validated Teacher Commitment scale with 13 items measured can be proposed to be used as an evaluative tool to assess the level to which teachers are committed to their students’ learning, teaching, school, and profession. The Teacher Commitment scale would also facilitate the identifications of factors that influence teachers’ quality of work life and school effectiveness. The practical implications, school cultural influence, and methodological limitations are discussed.

  4. Security-constrained unit commitment with flexible operating modes

    Science.gov (United States)

    Lu, Bo

    The electricity industry throughout the world, which has long been dominated by vertically integrated utilities, is facing enormous challenges. To enhance the competition in electricity industry, vertically integrated utilities are evolving into a distributed and competitive industry in which market forces drive the price of electricity and possibly reduce the net cost of supplying electrical loads through increased competition. To excel in the competition, generation companies (GENCOs) will acquire additional generating units with flexible operating capability which allows a timely response to the continuous changes in power system conditions. This dissertation considers the short-term scheduling of generating units with flexible modes of operation in security-constrained unit commitment (SCUC). Among the units considered in this study are combined cycle units, fuel switching/blending units, photovoltaic/battery system, pumped-storage units, and cascaded hydro units. The proposed security-constrained unit commitment solution will include a detailed model of transmission system which could impact the short-term scheduling of units with flexible operation modes.

  5. Evolution of Mindsight and Psychological Commitment among Strategically Interacting Agents

    Full Text Available We study the evolution of strategic psychological capabilities in a population of interacting agents. Specifically, we consider agents which are either blind or with mindsight, and either transparent or opaque. An agent with mindsight can observe the psychological makeup of a transparent agent, i.e., its logic, emotions, commitments and other elements that determine how it chooses actions. A blind agent cannot observe and opaque agents cannot be observed. Our assumption that mindsight and transparency are costly and optional exposes a middle ground between standard game theory without mindsight and evolution of preferences theory with obligatory and costless mindsight. We show that the only evolutionarily stable monomorphic population is one in which all agents are blind, opaque, and act-rational. We find that mindsight, transparency, and rule-rational commitments may evolve, albeit only in a portion of the population that fluctuates in size over generations. We reexamine the Ultimatum and Trust games in light of our findings and demonstrate that an evolved population of agents can differ significantly from a population of simplistic payoff-maximizers in terms of psychological traits and economic outcomes.

    Full Text Available The aim of this study was to contribute to the postulates of the self-determination theory, the hierarchical model of intrinsic and extrinsic motivation by Vallerand, and social goals. A structural regression model was estimated to analyze the relations between social goals (responsibility and relationships, praise for autonomous behavior, satisfaction of the basic psychological needs and intrinsic motivation in commitment to sport. A sample of 264 young Spanish soccer players aged between 14 and 16 (M =14.74, SD =.77 participated in the study. Structural Equation Modeling results showed that the social responsibility goal, the social relationship goal and praise for autonomous behavior predicted perceived competence. Furthermore, the relationship goal also predicted the need for relatedness. Satisfaction of the basic psychological needs for competence and relatedness predicted intrinsic motivation. Intrinsic motivation positively predicted future commitment to sport. These results highlighted the importance of social goals, praise for autonomous behavior and psychological mediators in encouraging greater commitment in young soccer players. Future research should focus on the coach’s role in generating greater commitment to sport through the development of intervention methodologies based on social goals.

  7. Cost-shifting under cost reimbursement and prospective payment.

    Science.gov (United States)

    Foster, R W

    1985-09-01

    Cost-shifting is seen as a three-way phenomenon involving hospital interests as well as those of government and private patients. Without economies of scale, private patients are indifferent to government policies unless underpayment leads to hospital bankruptcy. In the presence of economies of scale, private patients benefit from reductions in government payment under either cost reimbursement or prospective payment. Their interest in a shift to prospective payment depends upon the hospital's location on its cost curve. Hospitals benefit from increases in payment rates in all cases, but benefit from a shift to prospective payment only if operating in a region of declining average costs. The conventional view of cost-shifting is inconsistent with profit maximization and may be inappropriate for many voluntary hospitals as well.

  8. Assessing voluntary muscle activation with the twitch interpolation technique.

    Science.gov (United States)

    Shield, Anthony; Zhou, Shi

    2004-01-01

    The twitch interpolation technique is commonly employed to assess the completeness of skeletal muscle activation during voluntary contractions. Early applications of twitch interpolation suggested that healthy human subjects could fully activate most of the skeletal muscles to which the technique had been applied. More recently, however, highly sensitive twitch interpolation has revealed that even healthy adults routinely fail to fully activate a number of skeletal muscles despite apparently maximal effort. Unfortunately, some disagreement exists as to how the results of twitch interpolation should be employed to quantify voluntary activation. The negative linear relationship between evoked twitch force and voluntary force that has been observed by some researchers implies that voluntary activation can be quantified by scaling a single interpolated twitch to a control twitch evoked in relaxed muscle. Observations of non-linear evoked-voluntary force relationships have lead to the suggestion that the single interpolated twitch ratio can not accurately estimate voluntary activation. Instead, it has been proposed that muscle activation is better determined by extrapolating the relationship between evoked and voluntary force to provide an estimate of true maximum force. However, criticism of the single interpolated twitch ratio typically fails to take into account the reasons for the non-linearity of the evoked-voluntary force relationship. When these reasons are examined, it appears that most are even more challenging to the validity of extrapolation than they are to the linear equation. Furthermore, several factors that contribute to the observed non-linearity can be minimised or even eliminated with appropriate experimental technique. The detection of small activation deficits requires high resolution measurement of force and careful consideration of numerous experimental details such as the site of stimulation, stimulation intensity and the number of interpolated

    Full Text Available This paper describes the use of Chambers-Mallows-Stuck method for simulating stable random variables in the generation of test systems for economic analysis in power systems. A study that focused on generating test electrical systems through fat tail model for unit commitment problem in electrical power systems is presented. Usually, the instances of test systems in Unit Commitment are generated using normal distribution, but in this work, simulations data are based on a new method. For simulating, we used three original systems to obtain the demand behavior and thermal production costs. The estimation of stable parameters for the simulation of stable random variables was based on three generally accepted methods: (a regression, (b quantiles, and (c maximum likelihood, choosing one that has the best fit of the tails of the distribution. Numerical results illustrate the applicability of the proposed method by solving several unit commitment problems.

  11. Voluntary reaction time and long-latency reflex modulation.

    Stretching a muscle of the upper limb elicits short (M1) and long-latency (M2) reflexes. When the participant is instructed to actively compensate for a perturbation, M1 is usually unaffected and M2 increases in size and is followed by the voluntary response. It remains unclear if the observed increase in M2 is due to instruction-dependent gain modulation of the contributing reflex mechanism(s) or results from voluntary response superposition. The difficulty in delineating between these alternatives is due to the overlap between the voluntary response and the end of M2. The present study manipulated response accuracy and complexity to delay onset of the voluntary response and observed the corresponding influence on electromyographic activity during the M2 period. In all active conditions, M2 was larger compared with a passive condition where participants did not respond to the perturbation; moreover, these changes in M2 began early in the appearance of the response (∼ 50 ms), too early to be accounted for by voluntary overlap. Voluntary response latency influenced the latter portion of M2, with the largest activity seen when accuracy of limb position was not specified. However, when participants aimed for targets of different sizes or performed movements of various complexities, reaction time differences did not influence M2 period activity, suggesting voluntary activity was sufficiently delayed. Collectively, our results show that while a perturbation applied to the upper limbs can trigger a voluntary response at short latency (reflex gain modulation remains an important contributor to EMG changes during the M2 period.

  15. Interaction of poststroke voluntary effort and functional neuromuscular electrical stimulation.

    2013-01-01

    Functional electrical stimulation (FES) may be able to augment functional arm and hand movement after stroke. Poststroke neuroprostheses that incorporate voluntary effort and FES to produce the desired movement must consider how forces generated by voluntary effort and FES combine, even in the same muscle, in order to provide an appropriate level of stimulation to elicit the desired assistive force. The goal of this study was to determine whether the force produced by voluntary effort and FES add together independently of effort or whether the increment in force depends on the level of voluntary effort. Isometric force matching tasks were performed under different combinations of voluntary effort and FES. Participants reached a steady level of force, and while attempting to maintain a constant effort level, FES was applied to augment the force. Results indicate that the increment in force produced by FES decreases as the level of initial voluntary effort increases. Potential mechanisms causing the change in force output are proposed, but the relative contribution of each mechanism is unknown.

In this study, we used the Southampton Hand Assessment Procedure to examine functional differences between these two types of prehensors in 29 nondisabled subjects (who used a body-powered bypass prosthesis and 2 persons with unilateral transradial amputations (who used a conventional body-powered device. We also administered a survey to determine whether subjects preferred one prehensor or the other for specific tasks, with a long-term goal of assessing whether a prehensor that could switch between both modes would be advantageous. We found that using the voluntary closing prehensor was 1.3 s faster (p = 0.02 than using the voluntary opening prehensor, across tasks, and that there was consensus among subjects on which types of tasks they preferred to do with each prehensor type. Twenty-five subjects wanted a device that could switch between the two modes in order to perform particular tasks.

  17. Hedonic value of intentional action provides reinforcement for voluntary generation but not voluntary inhibition of action.

    Science.gov (United States)

    Parkinson, Jim; Haggard, Patrick

    2013-12-01

    Intentional inhibition refers to stopping oneself from performing an action at the last moment, a vital component of self-control. It has been suggested that intentional inhibition is associated with negative hedonic value, perhaps due to the frustration of cancelling an intended action. Here we investigate hedonic implications of the free choice to act or inhibit. Participants gave aesthetic ratings of arbitrary visual stimuli that immediately followed voluntary decisions to act or to inhibit action. We found that participants for whom decisions to act produced a strong positive hedonic value for the immediately following visual stimulus made more choices to act than those with weaker hedonic value for action. This finding is consistent with reinforcement learning of action decisions. However, participants who experienced inhibition as generating more positive hedonic value did not choose to inhibit more than other participants. Thus, voluntary inhibition of action did not act as reinforcement for future inhibitory behaviour. Our finding that inhibition of action lacks motivational capacity may explain why self-control is both difficult and limited.

  2. Voluntary control of human jaw stiffness.

    Science.gov (United States)

    Shiller, Douglas M; Houle, Guillaume; Ostry, David J

    2005-09-01

    Recent studies of human arm movement have suggested that the control of stiffness may be important both for maintaining stability and for achieving differences in movement accuracy. In the present study, we have examined the voluntary control of postural stiffness in 3D in the human jaw. The goal is to address the possible role of stiffness control in both stabilizing the jaw and in achieving the differential precision requirements of speech sounds. We previously showed that patterns of kinematic variability in speech are systematically related to the stiffness of the jaw. If the nervous system uses stiffness control as a means to regulate kinematic variation in speech, it should also be possible to show that subjects can voluntarily modify jaw stiffness. Using a robotic device, a series of force pulses was applied to the jaw to elicit changes in stiffness to resist displacement. Three orthogonal directions and three magnitudes of forces were tested. In all conditions, subjects increased the magnitude of jaw stiffness to resist the effects of the applied forces. Apart from the horizontal direction, greater increases in stiffness were observed when larger forces were applied. Moreover, subjects differentially increased jaw stiffness along a vertical axis to counteract disturbances in this direction. The observed changes in the magnitude of stiffness in different directions suggest an ability to control the pattern of stiffness of the jaw. The results are interpreted as evidence that jaw stiffness can be adjusted voluntarily, and thus may play a role in stabilizing the jaw and in controlling movement variation in the orofacial system.

    Krippl, Martin; Karim, Ahmed A; Brechmann, André

    2015-01-01

    Whereas the somatotopy of finger movements has been extensively studied with neuroimaging, the neural foundations of facial movements remain elusive. Therefore, we systematically studied the neuronal correlates of voluntary facial movements using the Facial Action Coding System (FACS, Ekman et al., 2002). The facial movements performed in the MRI scanner were defined as Action Units (AUs) and were controlled by a certified FACS coder. The main goal of the study was to investigate the detailed somatotopy of the facial primary motor area (facial M1). Eighteen participants were asked to produce the following four facial movements in the fMRI scanner: AU1+2 (brow raiser), AU4 (brow lowerer), AU12 (lip corner puller) and AU24 (lip presser), each in alternation with a resting phase. Our facial movement task induced generally high activation in brain motor areas (e.g., M1, premotor cortex, supplementary motor area, putamen), as well as in the thalamus, insula, and visual cortex. BOLD activations revealed overlapping representations for the four facial movements. However, within the activated facial M1 areas, we could find distinct peak activities in the left and right hemisphere supporting a rough somatotopic upper to lower face organization within the right facial M1 area, and a somatotopic organization within the right M1 upper face part. In both hemispheres, the order was an inverse somatotopy within the lower face representations. In contrast to the right hemisphere, in the left hemisphere the representation of AU4 was more lateral and anterior compared to the rest of the facial movements. Our findings support the notion of a partial somatotopic order within the M1 face area confirming the "like attracts like" principle (Donoghue et al., 1992). AUs which are often used together or are similar are located close to each other in the motor cortex.

    Full Text Available Whereas the somatotopy of finger movements has been extensively studied with neuroimaging, the neural foundations of facial movements remain elusive.

    Movement-related cortical potentials (MRCPs) are negative potentials over the scalp, which gradually increase prior to voluntary movements, and might be applied to elucidate the cortical efferent function of the mandibular movements. We compared the MRCPs accompanying various mandibular movements to study the motor control mechanism underlying these movements. Electroencephalograms (EEGs) were recorded from 11 electrodes placed over the scalp (F3, Fz, F4, T3, C3, Cz, C4, T4, P3, Pz, and P4), according to the International 10-20 System, and electromyograms (EMGs) were obtained from surface electrodes over the masseter muscle and the anterior belly of the digastric muscle. Ten healthy subjects were requested to make brisk and self-paced mandibular movements in 4 different directions (mouth-opening and -closing, and left and right lateral movements). We obtained MRCPs by averaging the EEG, using the visually determined EMG onset as a trigger signal. In all the movements, a slowly increasing, bilaterally widespread negativity starting 1.5 to 2.0 sec before the EMG onset (Bereitschaftspotential, or BP proper) was observed, with the maximum over the vertex region. The negative slope (NS') occurred about 300 to 700 msec before the EMG onset. The cortical maps of BP/NS' (BP and NS' combined), immediately prior to the mouth-opening and closing, showed a symmetrical distribution, whereas that for the lateral movements showed a tendency of predominance over the hemisphere ipsilateral to the direction of the movement. BP/NS' amplitudes at the onset of movement differed significantly or tended to do so between open, close, and lateral movements, suggesting that MRCP recordings may thus provide a means to explore the role of the cerebral cortex in the control of mandibular movements.

  6. Voluntary organizations in development in South Asia.

    The governments of South Asian countries have become aware of the substantial role that nongovernment organizations (NGOs) or voluntary agencies can play in rural development and other nation building activities. Although private agencies cannot substitute for government programs, there is general consensus that NGOs use development funds more efficiently and innovatively than government programs. NGOs in Bangladesh, India, and Pakistan exemplify the influence these organizations have on development in South Asia. The Lutheran World Service in Bangladesh, a foreign origin NGO, has branched out from its original aim of providing relief and war rehabilitation to give skills training and technical assistance to the poor. The Bangladesh Rural Advancement Committee, an indigenous NGO, works for the well-being and self-reliance of the landless poor, those with very small farms, and women. NGOs in Bangladesh have been especially innovative in developing methods to encourage self-help, such as local organization and credit, which are often combined with training in practical skills, literacy, nutrition, and family planning. Present NGO activity in India is dominated by the Gandhian tradition. There is a potential conflict between the philosophy of the NGO's in terms of building on the people's felt needs from the bottom up and the tendency of government agencies to want to plan for the people. In Pakistan, the concept of development-oriented NGOs is recent and not yet strong, although the government has adopted a policy of routing funds from government and from bilateral donor agencies through NGOs in 2 areas--family planning and women's welfare. The chief limitation of NGOs is their scope, meaning that the major burden of the development process rests on government agencies.

    Voluntary medical male circumcision is one of the most effective measures in preventing male acquisition of HIV during heterosexual intercourse. In Kenya, the voluntary medical male circumcision programme was launched in the year 2008 as part of a comprehensive national HIV prevention strategy. With the global challenge of funding HIV intervention programs, the sustainability of the programme beyond the donor periods need to be assessed. The purpose of this study was to determine the household ability and willingness to pay for voluntary medical male circumcision as an alternative method of funding the programme. The findings show that 62.2% of the households were "able" to pay for medical circumcision. However, 60.4% of them were not "willing" to pay for the service regardless of the cost. The findings indicate that ability to pay is not a significant predictor of willingness to pay for voluntary medical male circumcision within Kisumu County. Knowledge on the role of medical circumcision is a more important factor in determining willingness to pay for the service.

  8. The Effect of Mood on Opposite-Sex Judgments of Males' Commitment and Females' Sexual Intent

    Full Text Available Gender differences in perceptions of sexual intent and commitment have been the subject of formal and informal inquiry for considerable time. One evolutionary theory, Error Management Theory (EMT, predicts that opposite-sex perceptions of female sexual intent and male commitment intent reflect intrinsic biases that minimize gender-specific evolutionary costs. The results supporting these hypotheses were obtained from subjects regardless of mood. We hypothesized that mood would influence ratings of sexual and commitment intent. Sixty participants (30 males, 30 females were recruited and exposed to a positive and negative mood condition in counterbalanced groups using video stimuli. Preliminary analyses found an unexpected effect of order of mood induction, necessitating separate analyses of the Positive-Negative (PN and Negative-Positive (NP groups. Contrary to the original study, there were no gender effects. Positive moods led to increased ratings of both sexual and commitment intent across genders. Further, negative to positive mood-change was associated with significantly increased ratings. Both males and females attributed significantly higher sexual intent to same-sex rivals than themselves, but only males assessed themselves as having significantly higher commitment intent than same-sex rivals. The EMT model may require adaptation to acknowledge effects of variables such as mood on its predictions of gender-specific biases.

  9. The price of commitment in online stochastic vehicle routing

    This paper considers online stochastic multiple vehicle routing with time windows in which requests arrive dynamically and the goal is to maximize the number of serviced customers. Early work has focused on very flexible routing settings where the decision to assign a vehicle to a customer is delayed until a vehicle is actually deployed to the customer. Motivated by real applications that require stability in the decision making, this paper considers a setting where the decision to assign a customer request to a vehicle must be taken when that request is accepted. Experimental results suggest that this constraint severely degrades the performance of existing algorithms. However, the paper shows how the use of stochastic information for vehicle assignment and request acceptance improves decision quality considerably. Moreover, the use of resource augmentation quantifies precisely the cost of commitment in online vehicle routing.

    Health anxiety (or hypochondriasis) is prevalent, may be persistent and disabling for the sufferers and associated with high societal costs. Acceptance and Commitment Therapy (ACT) is a new third-wave behavioral cognitive therapy that has not yet been tested in health anxiety. 34 consecutive Danish...... patients with severe health anxiety were referred from general practitioners or hospital departments and received a ten session ACT group therapy. Patients were followed-up by questionnaires for 6 months. There were significant reductions in health anxiety, somatic symptoms and emotional distress at 6...... months compared to baseline: a 49% reduction in health anxiety (Whiteley-7 Index), a 47% decrease in emotional distress (SCL-8) and a 40% decrease in somatic symptoms (SCL-90-R). Furthermore, the patients’ perceptions of their illness (IPQ, a condensed Danish version) were significantly more optimistic...

    Global warming has consequences on the environment and economy; this led to the establishment of United Nation Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol. These two agreements were to reduce greenhouse gases (GHG) emissions which are responsible for climate change and global warming. Developing countries under the protocol are not obligated to reduce or disclosure GHG emission, so their participation in the protocol is on voluntary mitigation bases. This study intends to examine economic factors that influence voluntary carbon disclosure in the property sub-sector of developing countries based on annual report of listed property companies in Malaysia. Signaling theory addresses the problem of information asymmetry in the society. Disclosure is an effective tool to overcome information imbalance among different market participants. The study hypothesizes that the economic factors that influence voluntary carbon information disclosure in developing countries are: [1] the company's size; this is because a large-sized company have more resources to cover the cost of reducing pollution. [2] The company's gearing status; where there is no sufficient information disclosure in a highly geared company will result to an increased agency cost. [3] Profitability; profits grants companies a pool of resources for mitigation activities and environmental reporting. Also, carbon disclosure acts as a means for achieving public confidence and legitimacy. [4] Liquidity: Companies that are highly liquid will disclosure more information to distinguish themselves from other companies that are less liquidity. This is correlated to environmental disclosure. [5] Financial slack affects companies’ ability to participate in green technology projects that enable a reduction in emission.

    Caregivers' commitment to personal values is linked to caregivers' well-being, although the effects of personal values on caregivers' guilt have not been explored to date. The goal of this study is to analyze the relationship between caregivers´ commitment to personal values and guilt feelings. Participants were 179 dementia family caregivers. Face-to-face interviews were carried out to describe sociodemographic variables and assess stressors, caregivers' commitment to personal values and guilt feelings. Commitment to values was conceptualized as two factors (commitment to own values and commitment to family values) and 12 specific individual values (e.g. education, family or caregiving role). Hierarchical regressions were performed controlling for sociodemographic variables and stressors, and introducing the two commitment factors (in a first regression) or the commitment to individual/specific values (in a second regression) as predictors of guilt. In terms of the commitment to values factors, the analyzed regression model explained 21% of the variance of guilt feelings. Only the factor commitment to family values contributed significantly to the model, explaining 7% of variance. With regard to the regression analyzing the contribution of specific values to caregivers' guilt, commitment to the caregiving role and with leisure contributed negatively and significantly to the explanation of caregivers' guilt. Commitment to work contributed positively to guilt feelings. The full model explained 30% of guilt feelings variance. The specific values explained 16% of the variance. Our findings suggest that commitment to personal values is a relevant variable to understand guilt feelings in caregivers.

  14. Competition with Variety Seeking and Habitual Consumption: Price Commitment or Quality Commitment?

    2017-01-01

    Full Text Available This paper investigates price and quality competition in a market where consumers seek variety and habit formation. Variety seeking is modeled as a decrease in the willingness to pay for product purchased on the previous occasion while habitual consumption may increase future marginal utility. We compare two competing strategies: price commitment and quality commitment. With a three-stage Hotelling-type model, we show that variety seeking intensifies while habitual consumption softens the competition. With price commitment, firms supply lower quality levels in period 1 and higher quality levels in period 2, while, with quality commitment, firms charge higher prices in period 1 and lower prices in period 2. However, the habitual consumption brings the opposite effect. In addition, with quality commitment variety seeking leads to a lower profit and a higher consumer surplus, while habitual consumption leads to the opposite results. On the other side, with price commitment these behaviors have no effect on the consumer surplus, although they still lower down the firm profits. Finally, we also identify conditions under which one strategy outperforms the other.

    The fixation of cooperation among unrelated individuals is one of the fundamental problems in biology and social sciences. It is investigated by means of public goods games, the generalization of the prisoner's dilemma to more than two players. In compulsory public goods games, defect is the dominant strategy, while voluntary participation overcomes the social dilemma by allowing a cyclic coexistence of cooperators, defectors, and non-participants. Experimental and theoretical research has shown how the combination of voluntary participation and altruistic punishment-punishing antisocial behaviors at a personal cost-provides a solution to the problem, as long as antisocial punishment-the punishing of cooperators-is not allowed. Altruistic punishment can invade at low participation and pave the way to the fixation of cooperation. Specifically, defectors are overpunished, in the sense that their payoff is reduced by a sanction proportional to the number of punishers in the game. Here we show that qualitatively equivalent results can be achieved with a milder punishing mechanism, where defectors only risk a fixed penalty per round-as in many real situations-and the cost of punishment is shared among the punishers. The payoffs for the four strategies-cooperate, defect, abstain, and cooperate-&-punish-are derived and the corresponding replicator dynamics analyzed in full detail.

    The phenomena of cooperation in animal and human society are ubiquitous, but the selfish outcome that no player contributes to the public good will lead to the “tragedy of the commons”. The recent research shows that high punishment can improve the cooperation of the population. In this paper, we introduce a punishment mechanism into spatial voluntary public goods games with every individual only knowing his own payoff in each round. Using the self-adjusting rules, we find that the different cost for punishment can lead to different effects on the voluntary public goods games. Especially, when the cost for punishment is decreased, a higher contribution region will appear in the case of low r value. It means even for the low r value, individuals can form the contributing groups in large quantities to produce a more efficient outcome than that in moderate r value. In addition, we also find the players' memory can have effects on the average outcome of the population.

    HIV testing in prison settings has been identified as an important mechanism to detect cases among high-risk, underserved populations. Several public health organizations recommend that testing across health-care settings, including prisons, be delivered in an opt-out manner. However, implementation of opt-out testing within prisons may pose challenges in delivering testing that is informed and understood to be voluntary. In a large state prison system with a policy of voluntary opt-out HIV testing, we randomly sampled adult prisoners in each of seven intake prisons within two weeks after their opportunity to be HIV tested. We surveyed prisoners' perception of HIV testing as voluntary or mandatory and used multivariable statistical models to identify factors associated with their perception. We also linked survey responses to lab records to determine if prisoners' test status (tested or not) matched their desired and perceived test status. Thirty-eight percent (359/936) perceived testing as voluntary. The perception that testing was mandatory was positively associated with age less than 25 years (adjusted relative risk [aRR]: 1.45, 95% confidence interval [CI]: 1.24, 1.71) and preference that testing be mandatory (aRR: 1.81, 95% CI: 1.41, 2.31) but negatively associated with entry into one of the intake prisons (aRR: 0.41 95% CI: 0.27, 0.63). Eighty-nine percent of prisoners wanted to be tested, 85% were tested according to their wishes, and 82% correctly understood whether or not they were tested. Most prisoners wanted to be HIV tested and were aware that they had been tested, but less than 40% understood testing to be voluntary. Prisoners' understanding of the voluntary nature of testing varied by intake prison and by a few individual-level factors. Testing procedures should ensure that opt-out testing is informed and understood to be voluntary by prisoners and other vulnerable populations.

    Full Text Available NK cells can derive from the same precursors as B and T cells, however to achieve lineage specificity, several transcription factors need to be activated or annulled. While a few important transcription factors have identified for NK genesis the mechanisms of how this is achieved is far from resolved. Adding to the complexity of this, NK cells are found and potentially develop in diverse locations in vivo and it remains to be addressed if a common NK cell precursor seeds diverse niches and how transcription factors may differentially regulate NK cell commitment in distinct microenvironments. Here we will summarise some recent findings in NK cell commitment and discuss how a NK cell transcriptional network might be organised, while addressing some misconceptions and anomalies along the way.

    Previous research has shown that interpersonal coordination enhances pro-social attitudes and behavior. Here, we extend this research by investigating whether the degree of coordination observed in a joint action enhances the perception of individuals' commitment to the joint action. In four experiments, participants viewed videos of joint actions. In the low coordination condition, two agents made independent individual contributions to a joint action. In the high coordination condition, the individual contributions were tightly linked. Participants judged whether and for how long the observed agents would resist a tempting outside option and remain engaged in the joint action. The results showed that participants were more likely to expect agents to resist outside options when observing joint actions with a high degree of coordination. This indicates that observing interpersonal coordination is sufficient to enhance the perception of commitment to joint action. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available This paper examined some common problems involving prepositions in learning a second language. Many students learning English as a foreign language commonly commit mistakes in prepositions. The aim of this paper is to survey the causes of errors in the use of prepositions that are frequently made by Iranian students. A diagnostic test (35 Multiple choice item was constructed to test the students proficiency in using these prepositions. The prepositions selected for this purpose were; to, in, at, on, with, of, from, for, about, during, into under, over and by. This test was given to a group of 35 intermediate students. The results indicated that the errors committed by the students were due to both Inter-lingual and Intra-lingual interferences. It is hoped that this research will help teachers of English Language to be aware of these problems and re-evaluate their teaching approach.

  7. Safe Commits for Transactional Featherweight Java

    Science.gov (United States)

    Thuong Tran, Thi Mai; Steffen, Martin

    Transactions are a high-level alternative for low-level concurrency-control mechanisms such as locks, semaphores, monitors. A recent proposal for integrating transactional features into programming languages is Transactional Featherweight Java (TFJ), extending Featherweight Java by adding transactions. With support for nested and multi-threaded transactions, its transactional model is rather expressive. In particular, the constructs governing transactions - to start and to commit a transaction - can be used freely with a non-lexical scope. On the downside, this flexibility also allows for an incorrect use of these constructs, e.g., trying to perform a commit outside any transaction. To catch those kinds of errors, we introduce a static type and effect system for the safe use of transactions for TFJ. We prove the soundness of our type system by subject reduction.

  8. Requirements as Goals and Commitments Too

    Science.gov (United States)

    Chopra, Amit K.; Mylopoulos, John; Dalpiaz, Fabiano; Giorgini, Paolo; Singh, Munindar P.

    In traditional software engineering research and practice, requirements are classified either as functional or non-functional. Functional requirements consist of all functions the system-to-be ought to support, and have been modeled in terms of box-and-arrow diagrams in the spirit of SADT. Non-functional requirements include desired software qualities for the system-to-be and have been described either in natural language or in terms of metrics. This orthodoxy was challenged in the mid-90 s by a host of proposals that had a common theme: all requirements are initially stakeholder goals and ought to be elicited, modeled and analyzed as such. Through systematic processes, these goals can be refined into specifications of functions the system-to-be needs to deliver, while actions assigned to external actors need to be executed. This view is dominating Requirements Engineering (RE) research and is beginning to have an impact on RE practice. We propose a next step along this line of research, by adopting the concept of conditional commitment as companion concept to that of goal. Goals are intentional entities that capture the needs and wants of stakeholders. Commitments, on the other hand, are social concepts that define the willingness and capability of an actor A to fulfill a predicate ϕ for the benefit of actor B, provided B (in return) fulfills predicate ψ for the benefit of actor A. In our conceptualization, goals are mapped to collections of commitments rather than functions, qualities, or actor assignments. We motivate the importance of the concept of commitment for RE through examples and discussion. We also contrast our proposal with state-of-the-art requirements modeling and analysis frameworks, such as KAOS, MAP, i * and Tropos.

  10. Credit And Growth Under Limited Commitment

    OpenAIRE

    We consider a linear growth model with idiosyncratic productivity shocks in which producers cannot commit to repay their loans. Borrowing constraints are determined endogenously by the borrowers incentives to repay, assuming that defaulters lose a share of output and are excluded from future trade in the credit market. We characterize necessary and sufficient conditions for the enforceability of a first-best equilibrium growth path. Weak property rights, impatient producers, and small produc...

  11. Constructing rich false memories of committing crime.

    Memory researchers long have speculated that certain tactics may lead people to recall crimes that never occurred, and thus could potentially lead to false confessions. This is the first study to provide evidence suggesting that full episodic false memories of committing crime can be generated in a controlled experimental setting. With suggestive memory-retrieval techniques, participants were induced to generate criminal and noncriminal emotional false memories, and we compared these false memories with true memories of emotional events. After three interviews, 70% of participants were classified as having false memories of committing a crime (theft, assault, or assault with a weapon) that led to police contact in early adolescence and volunteered a detailed false account. These reported false memories of crime were similar to false memories of noncriminal events and to true memory accounts, having the same kinds of complex descriptive and multisensory components. It appears that in the context of a highly suggestive interview, people can quite readily generate rich false memories of committing crime.

    Background The global HIV prevention community is implementing voluntary medical male circumcision (VMMC) programs across eastern and southern Africa, with a goal of reaching 80% coverage in adult males by 2015. Successful implementation will depend on the accessibility of commodities essential for VMMC programming and the appropriate allocation of resources to support the VMMC supply chain. For this, the United States President’s Emergency Plan for AIDS Relief, in collaboration with the World Health Organization and the Joint United Nations Programme on HIV/AIDS, has developed a standard list of commodities for VMMC programs. Methods and Findings This list of commodities was used to inform program planning for a 1-y program to circumcise 152,000 adult men in Swaziland. During this process, additional key commodities were identified, expanding the standard list to include commodities for waste management, HIV counseling and testing, and the treatment of sexually transmitted infections. The approximate costs for the procurement of commodities, management of a supply chain, and waste disposal, were determined for the VMMC program in Swaziland using current market prices of goods and services. Previous costing studies of VMMC programs did not capture supply chain costs, nor the full range of commodities needed for VMMC program implementation or waste management. Our calculations indicate that depending upon the volume of services provided, supply chain and waste management, including commodities and associated labor, contribute between US$58.92 and US$73.57 to the cost of performing one adult male circumcision in Swaziland. Conclusions Experience with the VMMC program in Swaziland indicates that supply chain and waste management add approximately US$60 per circumcision, nearly doubling the total per procedure cost estimated previously; these additional costs are used to inform the estimate of per procedure costs modeled by Njeuhmeli et al. in “Voluntary Medical

  1. Redefining RECs: Additionality in the voluntary Renewable Energy Certificate market

    Science.gov (United States)

    Gillenwater, Michael Wayne

    In the United States, electricity consumers are told that they can "buy" electricity from renewable energy projects, versus fossil fuel-fired facilities, through participation in a voluntary green power program. The marketing messages communicate to consumers that their participation and premium payments for a green label will cause additional renewable energy generation and thereby allow them to claim they consume electricity that is absent pollution as well as reduce pollutant emissions. Renewable Energy Certificates (RECs) and wind energy are the basis for the majority of the voluntary green power market in the United States. This dissertation addresses the question: Do project developers respond to the voluntary REC market in the United States by altering their decisions to invest in wind turbines? This question is investigated by modeling and probabilistically quantifying the effect of the voluntary REC market on a representative wind power investor in the United States using data from formal expert elicitations of active participants in the industry. It is further explored by comparing the distribution of a sample of wind power projects supplying the voluntary green power market in the United States against an economic viability model that incorporates geographic factors. This dissertation contributes the first quantitative analysis of the effect of the voluntary REC market on project investment. It is found that 1) RECs should be not treated as equivalent to emission offset credits, 2) there is no clearly credible role for voluntary market RECs in emissions trading markets without dramatic restructuring of one or both markets and the environmental commodities they trade, and 3) the use of RECs in entity-level GHG emissions accounting (i.e., "carbon footprinting") leads to double counting of emissions and therefore is not justified. The impotence of the voluntary REC market was, at least in part, due to the small magnitude of the REC price signal and lack of

    Climate change mitigation in developing economies is a balancing act, between economic development and environmental sustainability. The need for market friendly determinants for low carbon economy, without compromising economic development is of essence. The aim of the study is to determine market friendly factors, which motivates voluntary carbon information disclosure, in the real estate industry. The study modeled economic factor with three variables and financial market factor with three variables against voluntary carbon information disclosure in the real estate industry. Structural equation modeling was used for the modeling and content analysis was used to collect data on the level of voluntary carbon information disclosure, from 2013 annual reports of 126 real estate sector companies listed in the Kuala Lumpur Stock Exchange (KLSE). The model achieved a good fit, and was acceptable prediction. The results show that financial market factor has a significant predictive influence on voluntary carbon disclosure. The application of the result is that financial market factor is has a significantly positive influence on companies’ willingness to make voluntary carbon disclosure in the real estate industry. The result may be limited to the real estate industry that is highly leveraged on syndicated fund.

    2010-12-01

    In this theoretical paper, we review central concepts in the psychological literature on relationship commitment to provide a foundation to discuss two themes related to long-term romantic relationships and marriages. First, we describe and discuss the role that commitment plays in stabilizing romantic attachment. Second, we use empirical research on cohabitation to highlight how the formation of commitment can be undermined by what are now common trajectories of couple development. The first topic underscores an increasingly important role for commitment in an age of companionate marriage. The second topic draws attention to dynamics that can affect the strength of romantic commitments, especially in marriage.

    2008-01-01

    An involuntary outpatient commitment law became effective in Florida in January 2005. However, only 71 orders for outpatient commitment have been issued in three years, even though during that period 41,997 adults had two or more 72-hour involuntary emergency examinations under Florida's civil commitment law. This column describes the criteria for outpatient commitment in the Florida statute and discusses possible reasons for its low rate of use, including additional statutory criteria that make filing a petition for outpatient commitment difficult, lack of community treatment resources, and lack of enforcement mechanisms.

    1995-04-01

    This study examined the relationship of managerial strategy and nursing commitment in Australian hospitals. The general principles of managerial strategy and employee response were illustrated and the meaning of commitment and resistance were defined. Data were collected by questionnaire survey and interviews. The result demonstrated that the middle manager/nurse unit manager played an important role in generating nursing commitment in the workplace. Trust and identification were the most relevant components of nursing commitment. However, the study also found that there was still a high degree of distrust between senior management and nurses. Change strategies which nurse managers could apply to promote greater organizational commitment in nursing are discussed.

  8. Neurons controlling voluntary vocalization in the macaque ventral premotor cortex.

    Directory of Open Access Journals (Sweden)

    Gino Coudé

    Full Text Available The voluntary control of phonation is a crucial achievement in the evolution of speech. In humans, ventral premotor cortex (PMv and Broca's area are known to be involved in voluntary phonation. In contrast, no neurophysiological data are available about the role of the oro-facial sector of nonhuman primates PMv in this function. In order to address this issue, we recorded PMv neurons from two monkeys trained to emit coo-calls. Results showed that a population of motor neurons specifically fire during vocalization. About two thirds of them discharged before sound onset, while the remaining were time-locked with it. The response of vocalization-selective neurons was present only during conditioned (voluntary but not spontaneous (emotional sound emission. These data suggest that the control of vocal production exerted by PMv neurons constitutes a newly emerging property in the monkey lineage, shedding light on the evolution of phonation-based communication from a nonhuman primate species.

  9. Suicide and voluntary active euthanasia: why the difference in attitude?

    Science.gov (United States)

    Beech, I

    1995-06-01

    It appears that the attitudes of health professionals differ towards suicide and voluntary active euthanasia. An acceptance of, if not an agreement with, voluntary active euthanasia exists, while there is a general consensus that suicide should be prevented. This paper searches for a working definition of suicide, to discover ethical reasons for the negative value that suicide assumes, and also to provide a term of reference when comparing suicide with euthanasia. On arriving at a working definition of suicide, it is compared with voluntary active euthanasia. An analysis of utilitarian and deontological considerations is provided and proves to be inconclusive with respect to the ethical principles informing the attitudes of professionals. Therefore, a search for other influences is attempted; this indicates that psychological influences inform attitudes to a greater degree than ethical principles.

    2007-10-15

    The authors propose a twofold simulated annealing (twofold-SA) method for the optimization of fuzzy unit commitment formulation in this paper. In the proposed method, simulated annealing (SA) and fuzzy logic are combined to obtain SA acceptance probabilities from fuzzy membership degrees. Fuzzy load is calculated from error statistics and an initial solution is generated by a priority list method. The initial solution is decomposed into hourly-schedules and each hourly-schedule is modified by decomposed-SA using a bit flipping operator. Fuzzy membership degrees are the selection attributes of the decomposed-SA. A new solution consists of these hourly-schedules of entire scheduling period after repair, as unit-wise constraints may not be fulfilled at the time of an individual hourly-schedule modification. This helps to detect and modify promising schedules of appropriate hours. In coupling-SA, this new solution is accepted for the next iteration if its cost is less than that of current solution. However, a higher cost new solution is accepted with the temperature dependent total cost membership function. Computation time of the proposed method is also improved by the imprecise tolerance of the fuzzy model. Besides, excess units with the system dependent probability distribution help to handle constraints efficiently and imprecise economic load dispatch (ELD) calculations are modified to save the execution time. The proposed method is tested using standard reported data sets. Numerical results show an improvement in solution cost and time compared to the results obtained from other existing methods.

    The US Department of Energy, Carlsbad Area Office (DOE-CAO) has completed a voluntary release assessment sampling program at selected Solid Waste Management Units (SWMUs) at the Waste Isolation Pilot Plant (WIPP). This Voluntary Release Assessment/Corrective Action (RA/CA) report has been prepared for final submittal to the Environmental protection Agency (EPA) Region 6, Hazardous Waste Management Division and the New Mexico Environment Department (NMED) Hazardous and Radioactive Materials Bureau to describe the results of voluntary release assessment sampling and proposed corrective actions at the SWMU sites. The Voluntary RA/CA Program is intended to be the first phase in implementing the Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) and corrective action process at the WIPP. Data generated as part of this sampling program are intended to update the RCRA Facility Assessment (RFA) for the WIPP (Assessment of Solid Waste Management Units at the Waste Isolation Pilot Plant), NMED/DOE/AIP 94/1. This Final Voluntary RA/CA Report documents the results of release assessment sampling at 11 SWMUs identified in the RFA. With this submittal, DOE formally requests a No Further Action determination for these SWMUs. Additionally, this report provides information to support DOE`s request for No Further Action at the Brinderson and Construction landfill SWMUs, and to support DOE`s request for approval of proposed corrective actions at three other SWMUs (the Badger Unit Drill Pad, the Cotton Baby Drill Pad, and the DOE-1 Drill Pad). This information is provided to document the results of the Voluntary RA/CA activities submitted to the EPA and NMED in August 1995.

    Waste siting gridlock in the United States and Canada has led to experimentation with voluntary and hybrid or ``mixed mode`` siting. We review nuclear and hazardous waste voluntary siting (VS) results for selected cases in the U.S, and Canada. Findings indicate that VS is not a panacea, but that current siting efforts are inadequate tests of its potential. We suggest trials of improved VS protocols and more effort on hybrid approaches in which the developer chooses the site but is required to reach agreement on conditions with local stakeholders. Mixed mode siting may be better suited to the US context and its three-tiered governmental system.

    We investigated adults' voluntary control of 20 facial action units theoretically associated with 6 basic emotions (happiness, fear, anger, surprise, sadness, and disgust). Twenty young adults were shown video excerpts of facial action units and asked to reproduce them as accurately as possible. Facial Action Coding System (FACS; Ekman & Friesen, 1978a) coding of the facial productions showed that young adults succeeded in activating 18 of the 20 target actions units, although they often coactivated other action units. Voluntary control was clearly better for some action units than for others, with a pattern of differences between action units consistent with previous work in children and adolescents.

    Switzerland showed its commitment to innovation in health care since the early 80th, implementing agencies and government units with the mission to promote and to appropriately govern innovation. The Swiss Network of Technology Assessment (SNHTA was founded in 1998.

    The aim is the promotion and implementation of Health Technology Assessment projects in Switzerland by providing a neutral forum for the identification and the pursuit of common interests. This includes the coordination, exchange and dissemination of experiences of HTA projects and the implementation of the results. The collaboration in international projects is a priority. Ultimately SNHTA has the goal to improve efficacy, cost effectiveness and social accountability. An inventory survey amongst the members confirmed a high level of diverse specialised competencies, mainly employed within the institution. Only 20% of the HTA specific competencies are used for external activities.

    The need for integration of all partners in the field of innovation in a network has been recognised by the Swiss government. This lead to the creation of a webplatform in which all players involved in the business of medical technologies are involved.

    This platform (swiss medtech, includes patients, insurers, industry, universities and professional organisations. The joined activities include agreements on intellectual property and the integrated patient care chain. New ways to connect players in innovation are needed to face the challenge of increasing costs and diminishing resources.

    Full Text Available In the last few decades, the problem of voluntary disclosure of financial or non-financial information has been, in the attention of specialists, given the fact that information assimetry, as explained by the agency theory, has become an important factor for the actors of financial markets. High quality financial reports consistent with the IAS/IFRS, issued at regular intervals, have the role of offering data for in-depth financial analisys that can be the basis for decisions regarding stock market investments. The performance of company, estimated by using the EVA, MVA, VA indicators, are directly linked with the average cost of capital, which in turn is sensitive to the evolutions of the stock market, measured both by the level of the asset attached to the entity and of the level of financial market. The impact of voluntary disclosure on company’s performance in our paper has been studied on TUFE company listed on the Bucharest Stock Exchange, confirming a refined degree of predictability.

  7. Student public commitment in a school-based diabetes prevention project: impact on physical health and health behavior

    Full Text Available Abstract Background As concern about youth obesity continues to mount, there is increasing consideration of widespread policy changes to support improved nutritional and enhanced physical activity offerings in schools. A critical element in the success of such programs may be to involve students as spokespeople for the program. Making such a public commitment to healthy lifestyle program targets (improved nutrition and enhanced physical activity may potentiate healthy behavior changes among such students and provide a model for their peers. This paper examines whether student's "public commitment"--voluntary participation as a peer communicator or in student-generated media opportunities--in a school-based intervention to prevent diabetes and reduce obesity predicted improved study outcomes including reduced obesity and improved health behaviors. Methods Secondary analysis of data from a 3-year randomized controlled trial conducted in 42 middle schools examining the impact of a multi-component school-based program on body mass index (BMI and student health behaviors. A total of 4603 students were assessed at the beginning of sixth grade and the end of eighth grade. Process evaluation data were collected throughout the course of the intervention. All analyses were adjusted for students' baseline values. For this paper, the students in the schools randomized to receive the intervention were further divided into two groups: those who participated in public commitment activities and those who did not. Students from comparable schools randomized to the assessment condition constituted the control group. Results We found a lower percentage of obesity (greater than or equal to the 95th percentile for BMI at the end of the study among the group participating in public commitment activities compared to the control group (21.5% vs. 26.6%, p = 0.02. The difference in obesity rates at the end of the study was even greater among the subgroup of students who

  8. Women Like Being Valued for Sex, as Long as it is by a Committed Partner.

    How do women respond to being valued for sex by their partners? Although research supporting objectification theory suggests that women's reactions to sexual valuation are primarily negative, a separate body of research indicates that women expend significant effort to enhance their sexual appeal. Evolutionary perspectives suggest that whether women are more or less satisfied with partners who value them for sex may depend on how committed those partners are. Being sexually valued by a relatively uncommitted partner may violate women's desire to avoid short-term sexual relationships and thus may be negatively associated with relationship satisfaction. In contrast, being sexually valued by a highly committed partner may positively influence women's relationship satisfaction because it signals to them that they have successfully attracted a long-term relationship partner. Two studies of newly married couples supported these predictions. In Study 1 (N = 109), husbands' sexual valuation was positively associated with marital satisfaction among wives who perceived that those husbands were highly committed, but negatively associated with marital satisfaction among wives who perceived that those husbands were relatively less committed. Study 2 (N = 99) revealed the same pattern for wives (but not husbands) using a likely manifestation of sexual valuation-engaging in frequent sex. These findings join others to demonstrate that interpersonal processes do not have universally positive or negative implications for relationships; rather, their implications depend on the context in which they occur, including contexts that were reproductively beneficial or costly throughout evolutionary history.

    Full Text Available During the past few years, organizational commitment has been a major concern in different types of business activities including banking industry. In this paper, we present an empirical investigation to study the relationship between social entrepreneurship and organizational commitment. The proposed study of this paper adapts a standard questionnaire developed by Meyer and Allen [Meyer, J. P., & Allen, N. J. (1991. A three-component conceptualization of organizational commitment. Human resource management review, 1(1, 61-89]. Cronbach alpha has been calculated for affective commitment, employee engagement and normative commitment as 0.77, 0.79 and 0.61, respectively. The results of survey indicate that affective commitment, employee engagement and normative commitment have positively influenced organizational commitment, significantly. In addition, Freedman test has indicated that normative commitment is number one priority with mean rank of 2.85 followed by affective commitment with mean rank of 2.47 and employee engagement with the mean rank of 2.26.

  10. Reduced Cognitive-Motor Interference on Voluntary Balance Control in Older Tai Chi Practitioners.

    2016-01-01

    Recent dual-task studies suggest that Tai Chi practitioners displayed better control of standing posture and maintained a quicker response time of postural muscle activation during a stepping down activity. Whether this effect extends to voluntary balance control, specifically the limits of excursion of the center of pressure, remains to be examined. The purpose of this study was to evaluate the cognitive-motor interference pattern by examining the effects of a concurrently performed cognitive task on attention of voluntary balance control in older adults who are long-term practitioners of Tai Chi. Ten older Tai Chi practitioners and 10 age-matched nonpractitioners performed a voluntary balance task that required them to shift their weight to reach a preset target in the forward and backward directions, with (single task, ST) and without (dual task, DT) a secondary cognitive task, which was the counting backward task. The counting backward task required the individual to compute and verbalize a series of arithmetic differences between a given pair of randomly generated numbers. The cognitive task was also performed independently (cognitive-ST). All trials were performed in a random order. Balance outcomes included reaction time, movement velocity, and maximal excursion of the center of pressure provided by the NeuroCom system. Cognitive outcome was the number of correct responses generated within the 8-second trial during the ST and DT conditions. Outcome variables were analyzed using a 2-factor, group by task, analysis of variance. DT costs for the variables were calculated as the relative difference between ST and DT conditions and were compared between the 2 groups using independent t tests. Tai Chi practitioners displayed shorter reaction times (P motor and cognitive resources than older nonpractitioners during a fairly complex (dynamic) postural equilibrium task while performing a verbal working memory task. They exhibited lesser cognitive-motor interference

    Barker, Anne M.

    Engineering has been one of the most difficult fields for 'women to enter and in which to succeed. Although the percentage of female engineers has Increased, women are still seriously underrcpresented in the workforce. This study examined the effect offender on career commitment, success, satisfaction, and involvement in engineering, and the effect of personality and work environment on these variables. Alumni from an engineering school in the northeastern United States were surveyed. The questionnaire was analyzed using statistical and descriptive methods to determine relationships among these variables. Women's commitment scores were lower than men's when controlled for other variables, including satisfaction and involvement. Men had longer tenure as engineers than women, even when controlled for year of graduation, professional engineering status, and number of children. Women did not leave engineering in different proportions than men, but they did earn significantly less despite controlling for year of graduation and number of hours worked weekly. Some gender differences in workplace experience were also found, including having colleagues act protectively, being mistaken for secretaries, and seeing men progress faster in their careers than equally qualified women.

  1. Voluntary imitation in Alzheimer’s disease patients

    Directory of Open Access Journals (Sweden)

    Ambra eBisio

    2016-03-01

    Full Text Available Although Alzheimer's disease (AD primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients’ behaviour. The aim of the present study was to investigate whether voluntary motor imitation, i.e. a volitional mechanism that involves observing another person’s action and translating this perception into one’s own action, was affected in patients with Alzheimer’s disease. Further, we tested whether this ability was modulated by the nature of the observed stimulus by comparing the ability to reproduce the kinematic features of a human demonstrator with that of a computerized-stimulus. AD patients showed an intact ability to reproduce the velocity of the observed movements, particularly when the stimulus was a human agent. This result suggests that high-level cognitive processes involved in voluntary imitation might be preserved in mild and moderate stages of AD and that voluntary imitation abilities might benefit from the implicit interpersonal communication established between the patient and the human demonstrator.

    Directory of Open Access Journals (Sweden)

    Sejdic Ervin

    2010-02-01

    Full Text Available Abstract Background Electrodermal reactions (EDRs can be attributed to many origins, including spontaneous fluctuations of electrodermal activity (EDA and stimuli such as deep inspirations, voluntary mental activity and startling events. In fields that use EDA as a measure of psychophysiological state, the fact that EDRs may be elicited from many different stimuli is often ignored. This study attempts to classify observed EDRs as voluntary (i.e., generated from intentional respiratory or mental activity or involuntary (i.e., generated from startling events or spontaneous electrodermal fluctuations. Methods Eight able-bodied participants were subjected to conditions that would cause a change in EDA: music imagery, startling noises, and deep inspirations. A user-centered cardiorespiratory classifier consisting of 1 an EDR detector, 2 a respiratory filter and 3 a cardiorespiratory filter was developed to automatically detect a participant's EDRs and to classify the origin of their stimulation as voluntary or involuntary. Results Detected EDRs were classified with a positive predictive value of 78%, a negative predictive value of 81% and an overall accuracy of 78%. Without the classifier, EDRs could only be correctly attributed as voluntary or involuntary with an accuracy of 50%. Conclusions The proposed classifier may enable investigators to form more accurate interpretations of electrodermal activity as a measure of an individual's psychophysiological state.

    The decision to participate in a research intervention or to undergo medical treatment should be both informed and voluntary. The aim of the present study was to develop an instrument to measure the perceived voluntariness of parents making decisions for their seriously ill children. A total of 219 parents completed questionnaires within 10 days of making such a decision at a large, urban tertiary care hospital for children. Parents were presented with an experimental form of the Decision Making Control Instrument (DMCI), a measure of the perception of voluntariness. Data obtained from the 28-item form were analyzed using a combination of both exploratory and confirmatory factor analytic techniques. The 28 items were reduced to 9 items representing 3 oblique dimensions: Self-Control, Absence of Control, and Others' Control. The hypothesis that the 3-factor covariance structure of our model was consistent with that of the data was supported. Internal consistency for the scale as a whole was high (0.83); internal consistency for the subscales ranged from 0.68 to 0.87. DMCI scores were associated with measures of affect, trust, and decision self-efficacy, supporting the construct validity of the new instrument. The DMCI is an important new tool that can be used to inform our understanding of the voluntariness of treatment and research decisions in medical settings.

  18. Selection and inhibition mechanisms for human voluntary action decisions.

    Zhang, Jiaxiang; Hughes, Laura E; Rowe, James B

    2012-10-15

    One can choose between action alternatives that have no apparent difference in their outcomes. Such voluntary action decisions are associated with widespread frontal-parietal activation, and a tendency to inhibit the repetition of a previous action. However, the mechanism of initiating voluntary actions and the functions of different brain regions during this process remains largely unknown. Here, we combine computational modeling and functional magnetic resonance imaging to test the selection and inhibition mechanisms that mediate trial-to-trial voluntary action decisions. We fitted an optimized accumulator model to behavioral responses in a finger-tapping task in which participants were instructed to make chosen actions or specified actions. Model parameters derived from each individual were then applied to estimate the expected accumulated metabolic activity (EAA) engaged in every single trial. The EAA was associated with blood oxygenation level-dependent responses in a decision work that was maximal in the supplementary motor area and the caudal anterior cingulate cortex, consistent with a competitive accumulation-to-threshold mechanism for action decision by these regions. Furthermore, specific inhibition of the previous action's accumulator was related to the suppression of response repetition. This action-specific inhibition correlated with the activity of the right inferior frontal gyrus, when the option to repeat existed. Our findings suggest that human voluntary action decisions are mediated by complementary processes of intentional selection and inhibition.

  2. Voluntary agreements, implementation and efficiency. European relevance of case study results. Reflections on transferability to voluntary agreement schemes at the European level

    Energy Technology Data Exchange (ETDEWEB)

    Helby, Peter

    2000-04-01

    As a policy instrument, voluntary agreements often fascinate policy-makers.This is fuelled by a number of assumed advantages, such as the opportunity for co-operation rather than confrontation, speed and flexibility and the cost-effectiveness. Some advantages might even be accentuated at the European level: Co-operation has added advantage at the European level where the culture of consensus decision is strong. Flexibility is extra attractive for policy makers dealing with an economy less homogeneous than the average national economy. Speed is certainly welcomed by policy-makers otherwise faced with the slow-winding European legislative process. Cost-effectiveness is eagerly sought by European policy makers facing tight administrative budgets and staff limits. This report examines lessons from the VAIE case studies that may be useful to policy makers engaged in the development of voluntary approaches at the European level. These case studies are about voluntary agreement schemes for industrial energy efficiency deployed in Denmark, France, Germany, Netherlands, and Sweden. For a summary of these case studies, please refer to the the VAIE final report. More detailed information is available in the VAIE national reports. It needs to be emphasised that the empirical base is very narrow. The 'lessons' presented can only be hypotheses, based on an inductive leap from a very narrow experience. The reader will need to check these hypotheses against her own broader experience and personal judgement. According to the principle of subsidiarity, voluntary agreements should be implemented at the European level only if that would have significant advantage over national action. Action at the European level, rather than the national level, would have these potential advantages: Being more consistent with the development of the single market; Allowing higher demands on energy efficiency without negative effect on competitiveness and employment; Stimulating company

  3. A Literature Review on Organizational Commitment – A Comprehensive Summary

    Directory of Open Access Journals (Sweden)

    Sayani Ghosh

    2014-12-01

    Full Text Available The paper encapsulates the evolution of the concept of organizational commitment, and its constructs. It focuses and analyses the literature findings of organizational commitments over the last five decades. It categorizes the approaches into six broad eras, each era being an extension and modification over the preceding ones. This review paper brings to the fore the theories that have emerged in the body of knowledge regarding commitment in organizations in a chronological order, starting from the side bet theory to the more recent multiple commitment approach. The gaps in the theories proposed have been identified and reviewed critically. It is difficult to conceptualize and measure organizational commitment as it encompasses a vast and highly diverse body of knowledge. Due to this it becomes difficult to interpret and conclude from the existing bodies of literature. The paper also highlights the importance of recognizing the individual/employee‟s perspective towards organizational commitment.

    Bit commitment is a fundamental cryptographic primitive in which Bob wishes to commit a secret bit to Alice. Perfectly secure bit commitment between two mistrustful parties is impossible through asynchronous exchange of quantum information. Perfect security is however possible when Alice and Bob split into several agents exchanging classical and quantum information at times and locations suitably chosen to satisfy specific relativistic constraints. Here we report on an implementation of a bit commitment protocol using quantum communication and special relativity. Our protocol is based on [A. Kent, Phys. Rev. Lett. 109, 130501 (2012)] and has the advantage that it is practically feasible with arbitrary large separations between the agents in order to maximize the commitment time. By positioning agents in Geneva and Singapore, we obtain a commitment time of 15 ms. A security analysis considering experimental imperfections and finite statistics is presented.

    Full Text Available This paper presents a study on the effects of professional ethics and commitments on audit quality. The population of this survey includes all audit managers who were active in auditing official statements of different firms listed in Tehran Stock Exchange in 2014. The study designs a questionnaire in Likert scale and distributes it among 152 randomly selected managers. In our survey, professional ethics consists of four items including confidentiality and impartiality, professional competence, accountability and individual values while organizational commitment consists of three items including emotional commitment, continues commitment and fundamental commitment. Using Pearson correlation as well as regression models, the study has determined a positive and meaningful relationship between professional ethics as well as commitment and audit quality.

    Full Text Available The aim of this study was to check the association of factors like work environment, job security,pay satisfaction and participation in decision making; with organizational commitment of theemployees, working in the banking sector of Pakistan. Two hundred and fifteen (215 responses toquestionnaire-based survey were collected from managerial and non-managerial employees, andanalyzed. The analysis showed positive correlations between the dependent and independentvariables. The relation between job security and organizational commitment was the most significant,indicating that a secure job can yield higher level of commitment. Work environment also had asignificant relation with organizational commitment, showing that a healthy and friendly workenvironment may enhance an employee’s commitment towards his work and organization. Paysatisfaction and participation in decision-making had low correlations with organizationalcommitment. Age and tenure seemed to affect the commitment of employees, with highercommitment shown for higher age and tenure; whereas gender did not show significant change incommitment level of employees.

  7. Conflicting pressures on romantic relationship commitment for anxiously attached individuals.

    Anxious attachment predicts strong desires for intimacy and stability in romantic relationships, yet the relation between anxious attachment and romantic commitment is unclear. We propose that extant literature has failed to find a consistent relation because anxiously attached individuals experience conflicting pressures on commitment. Data from Australia (N=137) show that relationship satisfaction and felt security each act as suppressors of a positive relation between anxious attachment and commitment. Data from Japan (N=159) replicate the suppression effect of felt security and also demonstrate that the residual positive relation between anxious attachment and commitment can be partly explained by dependence on the partner. These findings suggest that anxiously attached individuals may be ambivalent about commitment. Dissatisfaction and worries about negative evaluation appear to exert downward pressure on commitment, counteracting the upward pressure that is exerted by factors such as relational dependency. © 2011 The Authors.

    2013-10-01

    Voluntary green power markets are those in which consumers and institutions voluntarily purchase renewable energy to match their electricity needs. Voluntary action provides a revenue stream for renewable energy projects and raises consumer awareness of the benefits of renewable energy. These markets continued to exhibit growth and stimulate renewable energy development in 2012. This paper reviews the voluntary market and identifies market trends.

  17. Which serial killers commit suicide? An exploratory study.

    Science.gov (United States)

    Lester, David; White, John

    2012-11-30

    In a sample of 483 serial killers, 6.2% were documented to have committed suicide. Those who committed suicide were found to come from more dysfunctional homes characterized by more psychiatric disturbance in the parents. The sexual acts involved in the murders by the suicides seemed to be more deviant in some aspects, such as committing more bizarre sexual acts or more often taping the murder.

  18. Investment Timing When External Financing Is Costly

    DEFF Research Database (Denmark)

    Hirth, Stefan; Uhrig-Homburg, Marliese

    2010-01-01

    This paper analyzes the investment timing of firms facing two dimensions of financing constraints: Liquidity constraints and capital market frictions inducing financing costs. We show that liquidity constraints are not sufficient to explain voluntary investment delay. However, when additionally...... considering financing costs, we can explain both voluntary delay and acceleration of investment. More precisely, we find that investment thresholds are U-shaped in liquid funds. For high-liquidity firms, investment thresholds are decreasing (i.e. accelerated investment takes place) in either dimension...... of financing constraint. In contrast, investment thresholds are increasing (i.e. investment is further delayed) in either form of financing constraint for low-liquidity firms. For intermediate levels of liquidity, investment thresholds are U-shaped in market frictions....

  19. Genetic Algorithm Based Simulated Annealing Method for Solving Unit Commitment Problem in Utility System

    Science.gov (United States)

    Rajan, C. Christober Asir

    2010-10-01

    The objective of this paper is to find the generation scheduling such that the total operating cost can be minimized, when subjected to a variety of constraints. This also means that it is desirable to find the optimal generating unit commitment in the power system for the next H hours. Genetic Algorithms (GA's) are general-purpose optimization techniques based on principles inspired from the biological evolution using metaphors of mechanisms such as neural section, genetic recombination and survival of the fittest. In this, the unit commitment schedule is coded as a string of symbols. An initial population of parent solutions is generated at random. Here, each schedule is formed by committing all the units according to their initial status ("flat start"). Here the parents are obtained from a pre-defined set of solution's i.e. each and every solution is adjusted to meet the requirements. Then, a random recommitment is carried out with respect to the unit's minimum down times. And SA improves the status. A 66-bus utility power system with twelve generating units in India demonstrates the effectiveness of the proposed approach. Numerical results are shown comparing the cost solutions and computation time obtained by using the Genetic Algorithm method and other conventional methods.

  20. Voluntary reduction of trans-fatty acids in Latin America and the Caribbean: current situation.

    Monge-Rojas, Rafael; Colón-Ramos, Uriyoán; Jacoby, Enrique; Mozaffarian, Dariush

    2011-02-01

    As part of the Pan American Health Organization/World Health Organization Trans-Fat-Free Americas initiative, 12 representatives from food industries in Latin America and the Caribbean signed a declaration stating their intention to voluntarily eliminate industrially produced trans-fatty acids (TFA) from the Americas. A year later, in order to document the extent of the voluntary reduction, each declarant was asked to describe all reformulations and reductions in the TFA content of their products. After up to six requests for data, only three declarants provided such information in detail, and three others offered an overall summary of their reformulations. Additionally, three declarants reported the barriers that limit this process: availability of oil substitutes, cost, and consumers' sensory acceptance. The content of TFA and saturated fat in the food supply in the Americas should be regulated and strictly monitored in order to adequately evaluate a reduction of TFA in the region.
