    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.

    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.

    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.

    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)

    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.

    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.

    2013-02-01

    Full Text Available A review of the research methodology literature suggests that owing to the difficulty of gaining access to and obtaining commitments from elites, social scientists less frequently use them as research respondents, opting instead to investigate those over whom power is exercised. This article provides insights into some intricacies of elite interviewing. It recounts the experience of a novice researcher in his quest to gain access to and interview elite individuals within the Ghanaian educational system for his PhD thesis. In the process, the article sheds light on strategies and techniques (related to interviewee identification, scheduling, and researcher preparation for the interview, as well as rapport establishment with potential interviewees that are helpful as toolkits in ensuring that elite interview processes are not unduly derailed. The article argues that the strategies discussed are useful for circumventing formalised and “public relations” responses, which elites tend to communicate with the press and public.

    Lima, Ricardo

    2015-12-11

    This paper addresses the study of symmetry in Unit Commitment (UC) problems solved by Mixed Integer Linear Programming (MILP) formulations, and using Linear Programming based Branch & Bound MILP solvers. We propose three sets of symmetry breaking constraints for UC MILP formulations exhibiting symmetry, and its impact on three UC MILP models are studied. The case studies involve the solution of 24 instances by three widely used models in the literature, with and without symmetry breaking constraints. The results show that problems that could not be solved to optimality within hours can be solved with a relatively small computational burden if the symmetry breaking constraints are assumed. The proposed symmetry breaking constraints are also compared with the symmetry breaking methods included in two MILP solvers, and the symmetry breaking constraints derived in this work have a distinct advantage over the methods in the MILP solvers.

  3. United States commitment to heavy lift launch vehicles

    Science.gov (United States)

    Gabris, Edward A.

    Observers of the United States' space program will note progress toward the development of a new launch system capable of supporting the nation's future space missions. The process of defining mission requirements, developing technically and politically acceptable solutions, making policy decisions, and developing budget support in a democratic society is protracted, but eventually yields decisions that represent the public interest. The consensus developing within the United States on a new launch capability including heavy-lift is embodied in the Joint NASA/DoD National Launch System. This launch vehicle concept has emerged after more than five years of studies by NASA, the DoD and every major industrial aerospace contractor in the U.S. In July 1991, Vice President Quayle, in his capacity as Chairman of the National Space Council stated the Nation's commitment to support of the NLS. This paper reviews progress to date, and the involvement of the four major constituencies; the Executive Branch operating through the National Space Council, the Legislative Branch, the various elements of the DoD, and NASA. The evolution of launch system "requirements", along with the form, content and rationale for the various decisions that have been made will be described and discussed.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    2015-09-01

    Penetration of renewable energy resources, such as wind and solar power, into power systems significantly increases the uncertainties on system operation, stability, and reliability in smart grids. In this paper, the nonparametric neural network-based prediction intervals (PIs) are implemented for forecast uncertainty quantification. Instead of a single level PI, wind power forecast uncertainties are represented in a list of PIs. These PIs are then decomposed into quantiles of wind power. A new scenario generation method is proposed to handle wind power forecast uncertainties. For each hour, an empirical cumulative distribution function (ECDF) is fitted to these quantile points. The Monte Carlo simulation method is used to generate scenarios from the ECDF. Then the wind power scenarios are incorporated into a stochastic security-constrained unit commitment (SCUC) model. The heuristic genetic algorithm is utilized to solve the stochastic SCUC problem. Five deterministic and four stochastic case studies incorporated with interval forecasts of wind power are implemented. The results of these cases are presented and discussed together. Generation costs, and the scheduled and real-time economic dispatch reserves of different unit commitment strategies are compared. The experimental results show that the stochastic model is more robust than deterministic ones and, thus, decreases the risk in system operations of smart grids.

    2012-03-01

    Full Text Available Utilities participating in deregulated markets observe increasing uncertainty in load (i.e., demand for electric power and prices for fuel and electricity on spot and contract markets. This study proposes a new formulation of the unit commitment problem of electric power generators in a restructured electricity market. Under these conditions, an electric power generation company will have the option to buy or sell from a power pool in addition to producing electricity on its own. The unit commitment problem is expressed as a stochastic optimization problem in which the objective is to maximize expected profits and the decisions are required to meet the standard operating constraints. Under the assumption of competitive market and price taking, it is depicted that the unit commitment schedule for a collection of N generation units can be solved by considering each unit separately. The volatility of the spot market price of electricity is represented by a stochastic model. This paper uses probabilistic dynamic programming to solve the stochastic optimization problem pertaining to unit commitment. It is shown that for a market of 150 units the proposed unit commitment can be accurately solved in a reasonable time by using the normal, Edgeworth, or Monte Carlo approximation methods.

    Full Text Available In this paper security constraints unit commitment (SCUC in the presence of wind power resources and electrical vehicles to grid is presented. SCUC operation prepare an optimal time table for generation unit commitment in order to maximize security, minimize operation cost and satisfy the constraints of networks and units in a period of time, as one of the most important research interest in power systems. Today, the relationship between power network and energy storage systems is interested for many researchers and network operators. Using Electrical Vehicles (PEVs and wind power for energy production is one of the newest proposed methods for replacing fossil fuels.One of the effective strategies for analyzing of the effects of Vehicle 2 Grid (V2G and wind power in optimal operation of generation is running of SCUC for power systems that are equipped with V2G and wind power resources. In this paper, game theory method is employed for deterministic solution of day-ahead unit commitment with considering security constraints in the simultaneous presence of V2G and wind power units. This problem for two scenarios of grid-controlled mode and consumer-controlled mode in three different days with light, medium and heavy load profiles is analyzed. Simulation results show the effectiveness of the presence of V2G and wind power for decreasing of generation cost and improving operation indices of power systems.

    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.

    Electric power system is one of the most important and complex engineering in modern society, supplying main and general power for social production and social life. Meanwhile, since it is a productive system with both high input and output, it has an obvious economic significance to improve its operating efficiency. For an example, an unit is 10 GW year. It will be discussed mainly that how to establish optimization model and its numerical algorithm for operating management of the electric power system. The idea on establishing optimization model is how to dispatch work state of units or power plants, so that total cost of fuel consumption for generation is reduced to the minimum. Here the dispatch is to decide which unit or plant to operate, which unit or plant to stop running, how much power should be generated for those operating units or plants at each given time interval.

    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.

    2009-01-01

    Full Text Available As President Obama is in the midst of deciding whether additional U.S.combat forces are needed in Afghanistan in addition to the 21,000 troops recently committed, he must realize that additional armed forces are only a stopgap measure in Afghanistan's downward spiral into an 'undergoverned' failed state. Similarly, as Pakistan's fragile and fractured civilian government continues to appease the Tehrik-i-Taliban Pakistan (TTP, an umbrella organization of Pakistani Pashtun tribesmen with Taliban cultural values led by Baitullah Mehsud and others, it comes closer to the concept of a "misgoverned" failed state, possessing a small arsenal of nuclear arms. The problem for the U.S. administration is that neither of these countries can be allowed to fall further into disrepair. At the same time each requires a different and unique approach to the threat of "Talibanization" that faces each country—the control of territory within each country by Islamic radicals seeking to impose their ultraconservative interpretation of shar'ia law onto the general populace. Generally acknowledged is the belief that what has tentatively worked in Iraq, that is, the additional U.S. troops and employment of former Sunni insurgents to help fight foreign fighters associated with al-Qaida, will not work in either Afghanistan or Pakistan. While a regional approach to the conflict in these two countries is warranted, Afghanistan and Pakistan are on two different economic, social, and political playing fields. Hence, there cannot be a one-size-fits-all solution for the two countries, especially one that draws on the Iraq playbook. In addition to its internal political problems, Pakistan also faces the issue of al-Qaida and Taliban training camps positioned in its literal back yard, the Federally Administered Tribal Areas (FATA or Tribal Areas. Resolution of the War on Terror cannot come to fruition without addressing the problems that exist in the Tribal Areas. This largely

  18. Locative Inversion In Discourse: a strategy of non-commitment

    Full Text Available In this paper, Locative Inversion (hence LI is analysed as the linear realization of a predication devoid of speaker’s commitment. First, we show that the syntactic constraints and modal restrictions already debated in the linguistic literature, form a coherent set of properties and are evidence of a non-speaker-based predication. Some examples of these properties are: LI’s incompatibility with negation or epistemic modalization, strong aspectual and temporal restrictions such as its incompatibility with BE+ING or generic interpretations.In the second part of this paper, we provide a discursive analyse of LI in two actual literary contexts: i first, when it occurs at the beginning of folktales; there, its predicative use is compared to there-sentences, the latter, we argue, being typically speaker-based predications; ii then, when it occurs in narrative’s descriptions (for instance in crime-scene description; there, LI appears in a context of internal focalization, with the make-belief effect of referring directly to the situation described as if it was perceptible by everyone.In both cases, it appears that LI occurs in contexts where the speaker is pragmatically determined. Its use depends on the need to resort to a "universal" commitment for the predication.Dans cet article, l'inversion locative (IL en anglais est étudiée en tant que réalisation syntaxique d'une prédication dénuée de toute prise en charge identifiée à un sujet-parlant. Dans une première partie, on s'attache à montrer que les contraintes syntaxiques et les restrictions modales, connues dans la littérature et qui caractérisent la forme, signalent que l'inversion locative est la trace d’une prédication objectivée. Les contraintes observées sont par exemple l’incompatibilité avec les formes de remise en cause de l’assertion (négation ou modalisation épistémique, les fortes restrictions des déterminations aspectuelles (notamment BE

    This paper presents a new approach for unit commitment problem using Stochastic Priority List method. In this method, rapidly some initial unit commitment schedules are generated by Priority List method and priority based stochastic window system. Excess units are added with system dependent probability distribution to avoid overlooking a desired solution during repeated search. Constraints are not considered in this stage. Then schedules are modified gradually using the problem specific heuristics to fulfill constraints. To reduce calculations, heuristics are applied only to the solutions, which can be expected to improve. Besides, sign vector is introduced to reduce economic load dispatch (ELD) overhead recalculations. This process is repeated for optimal solution. The proposed method is tested using the reported problem data set. Simulation results for the systems up to 100-unit are compared to previous reported results. Numerical results show an improvement in solution cost and time compared to the results obtained from Genetic Algorithm and others. (author)

  1. Two-level, two-objective evolutionary algorithms for solving unit commitment problems

    A two-level, two-objective optimization scheme based on evolutionary algorithms (EAs) is proposed for solving power generating Unit Commitment (UC) problems by considering stochastic power demand variations. Apart from the total operating cost to cover a known power demand distribution over the scheduling horizon, which is the first objective, the risk of not fulfilling possible demand variations forms the second objective to be minimized. For this kind of problems with a high number of decision variables, conventional EAs become inefficient optimization tools, since they require a high number of evaluations before reaching the optimal solution(s). To considerably reduce the computational burden, a two-level algorithm is proposed. At the low level, a coarsened UC problem is defined and solved using EAs to locate promising solutions at low cost: a strategy for coarsening the UC problem is proposed. Promising solutions migrate upwards to be injected into the high level EA population for further refinement. In addition, at the high level, the scheduling horizon is partitioned in a small number of subperiods of time which are optimized iteratively using EAs, based on objective function(s) penalized to ensure smooth transition from/to the adjacent subperiods. Handling shorter chromosomes due to partitioning increases method's efficiency despite the need for iterating. The proposed two-level method and conventional EAs are compared on representative test problems. (author)

    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.

    Full Text Available Due to the continuous increase of the population and the perpetual progress of industry, the energy management presents nowadays a relevant topic that concerns researchers in electrical engineering. Indeed, in order to establish a good exploitation of the electrical grid, it is necessary to solve technical and economic problems. This can only be done through the resolution of the Unit Commitment Problem. Unit Commitment Problem allows optimizing the combination of the production units’ states and determining their production planning, in order to satisfy the expected consumption with minimal cost during a specified period which varies usually from 24 hours to one week. However, each production unit has some constraints that make this problem complex, combinatorial, and nonlinear. This paper presents a comparative study between a strategy based on hybrid gradient-genetic algorithm method and two strategies based on metaheuristic methods, fuzzy logic, and genetic algorithm, in order to predict the combinations and the unit commitment scheduling of each production unit in one side and to minimize the total production cost in the other side. To test the performance of the optimization proposed strategies, strategies have been applied to the IEEE electrical network 14 busses and the obtained results are very promising.

    The unit commitment problem, originally conceived in the framework of short term operation of vertically integrated utilities, needs a thorough re-examination in the light of the ongoing transition towards the open electricity market environment. In this work the problem is re-formulated to adapt unit commitment to the viewpoint of a generation company (GENCO) which is no longer bound to satisfy its load, but is willing to maximize its profits. Moreover, with reference to the present day situation in many countries, the presence of a GENCO (the former monopolist) which is in the position of exerting the market power, requires a careful analysis to be carried out considering the different perspectives of a price taker and of the price maker GENCO. Unit commitment is thus shown to lead to a couple of distinct, yet slightly different problems. The unavoidable uncertainties in load profile and price behaviour over the time period of interest are also taken into account by means of a Monte Carlo simulation. Both the forecasted loads and prices are handled as random variables with a normal multivariate distribution. The correlation between the random input variables corresponding to successive hours of the day was considered by carrying out a statistical analysis of actual load and price data. The whole procedure was tested making use of reasonable approximations of the actual data of the thermal generation units available to come actual GENCOs operating in Italy. (author)

    We present a computational framework for integrating the state-of-the-art Weather Research and Forecasting (WRF) model in stochastic unit commitment/energy dispatch formulations that account for wind power uncertainty. We first enhance the WRF model with adjoint sensitivity analysis capabilities and a sampling technique implemented in a distributed-memory parallel computing architecture. We use these capabilities through an ensemble approach to model the uncertainty of the forecast errors. The wind power realizations are exploited through a closed-loop stochastic unit commitment/energy dispatch formulation. We discuss computational issues arising in the implementation of the framework. In addition, we validate the framework using real wind speed data obtained from a set of meteorological stations. We also build a simulated power system to demonstrate the developments.

    An improved two stages solution model to the unit commitment of thermal units is developed in this paper. In the first stage a pre-schedule is generated using a high quality trained artificial neural net (ANN). A dynamic programming (DP) algorithm is implemented and applied in the second stage for the final determination of the commitment states. The developed solution model avoids the complications imposed by the generation of the variable window structure, proposed by other techniques. A unified approach for the treatment of the ANN is also developed in the paper. The validity of the proposed technique is proved via numerical applications to both sample and small practical power systems. 12 refs, 9 tabs

    Full Text Available This paper presents a new approach to solve the profit based multi area unit commitment problem (PBMAUCP using an evolutionary programming based particle swarm optimization (EPPSO method. The objective of this paper is to maximize the profit of generation companies (GENCOs with considering system social benefit. The proposed method helps GENCOs to make a decision, how much power and reserve should be sold in markets, and how to schedule generators in order to receive the maximum profit. Joint operation of generation resources can result in significant operational cost savings. Power transfer between the areas through the tie lines depends upon the operating cost of generation at each hour and tie line transfer limits. The tie line transfer limits were considered as a set of constraints during optimization process to ensure the system security and reliability. The overall algorithm can be implemented on an IBM PC, which can process a fairly large system in a reasonable period of time. Case study of four areas with different load pattern each containing 7 units (NTPS and 26 units connected via tie lines have been taken for analysis. Numerical results showed comparing the profit of evolutionary programming-based particle swarm optimization method (EPPSO with conventional dynamic programming (DP, evolutionary programming (EP, and particle swarm optimization (PSO method. Experimental results shows that the application of this evolutionary programming based particle swarm optimization method have the potential to solve profit based multi area unit commitment problem with lesser computation time.

    Household waste management has become essential in industrialized countries. For the recycling programs to be a success, all citizens must comply with the developed residential procedures. Governmental bodies are thus dependent on as many people as possible adhering to the sorting systems they develop. Since the 1970s oil crisis, governments have called upon social psychologists to help develop effective communication strategies. These studies have been based on persuasion and behavioral commitment (Kiesler, 1971). Less common are studies based on developing participative communication (Horsley, 1977), a form of communication that relies on individuals to pass on information. After going through the main communication perspectives as they relate to the sorting of household waste, a comparative field study will be presented on the effectiveness of persuasive, committing and participative communication. Participative communication relied on users to pass along information to their neighbors. The results show that the participants who spread information in this way, along with those who made a commitment, changed their behavior to a greater degree than the other participants.

    Ant colony optimization (ACO) is successfully applied in optimization problems. Performance of the basic ACO for small problems with moderate dimension and searching space is satisfactory. As the searching space grows exponentially in the large-scale unit commitment problem, the basic ACO is not applicable for the vast size of pheromone matrix of ACO in practical time and physical computer-memory limit. However, memory-bounded methods prune the least-promising nodes to fit the system in computer memory. Therefore, the authors propose memory-bounded ant colony optimization (MACO) in this paper for the scalable (no restriction for system size) unit commitment problem. This MACO intelligently solves the limitation of computer memory, and does not permit the system to grow beyond a bound on memory. In the memory-bounded ACO implementation, A{sup *} heuristic is introduced to increase local searching ability and probabilistic nearest neighbor method is applied to estimate pheromone intensity for the forgotten value. Finally, the benchmark data sets and existing methods are used to show the effectiveness of the proposed method. (author)

  18. Metamodel-assisted evolutionary algorithms for the unit commitment problem with probabilistic outages

    An efficient method for solving power generating unit commitment (UC) problems with probabilistic unit outages is proposed. It is based on a two-level evolutionary algorithm (EA) minimizing the expected total operating cost (TOC) of a system of power generating units over a scheduling period, with known failure and repair rates of each unit. To compute the cost function value of each EA population member, namely a candidate UC schedule, a Monte Carlo simulation must be carried out. Some thousands of replicates are generated according to the units' outage and repair rates and the corresponding probabilities. Each replicate is represented by a series of randomly generated availability and unavailability periods of time for each unit and the UC schedule under consideration accordingly. The expected TOC is the average of the TOCs of all Monte Carlo replicates. Therefore, the CPU cost per Monte Carlo evaluation increases noticeably and so does the CPU cost of running the EA. To reduce it, the use of a metamodel-assisted EA (MAEA) with on-line trained surrogate evaluation models or metamodels (namely, radial-basis function networks) is proposed. A novelty of this method is that the metamodels are trained on a few ''representative'' unit outage scenarios selected among the Monte Carlo replicates generated once during the optimization and, then, used to predict the expected TOC. Based on this low cost, approximate pre-evaluation, only a few top individuals within each generation undergo Monte Carlo simulations. The proposed MAEA is demonstrated on test problems and shown to drastically reduce the CPU cost, compared to EAs which are exclusively based on Monte Carlo simulations. (author)

    2012-01-01

    Full Text Available Security-constrained unit commitment (SCUC is an important tool for independent system operators in the day-ahead electric power market. A serious issue arises that the energy realizability of the staircase generation schedules obtained in traditional SCUC cannot be guaranteed. This paper focuses on addressing this issue, and the basic idea is to formulate the power output of thermal units as piecewise-linear function. All individual unit constraints and systemwide constraints are then reformulated. The new SCUC formulation is solved within the Lagrangian relaxation (LR framework, in which a double dynamic programming method is developed to solve individual unit subproblems. Numerical testing is performed for a 6-bus system and an IEEE 118-bus system on Microsoft Visual C# .NET platform. It is shown that the energy realizability of generation schedules obtained from the new formulation is guaranteed. Comparative case study is conducted between LR and mixed integer linear programming (MILP in solving the new formulation. Numerical results show that the near-optimal solution can be obtained efficiently by the proposed LR-based method.

    This qualitative study was performed at the adult Intensive Care Unit (ICU) of a public hospital in Southern Brazil with the objective to evaluate the implemented welcoming strategies. Participants included 13 patients and 23 relatives. Data collection was performed from July to October 2008, utilizing semi-structured interviews. All interviews were recorded. Data analysis was performed using the Collective Subject Discourse. The collected information yielded two discourses: the family recognized the welcoming strategies and the patients found the ICU team to be considerate. By including the family as a client of nursing care, relatives felt safe and confident. Results show that by committing to the responsibility of making changes in heath care practices, nurses experience a novel outlook towards ICU care, focused on human beings and associating the welcoming to the health care model that promotes the objectivity of care.

    2010-01-01

    Full Text Available This paper presents the solving unit commitment (UC problem using Modified Subgradient Method (MSG method combined with Simulated Annealing (SA algorithm. UC problem is one of the important power system engineering hard-solving problems. The Lagrangian relaxation (LR based methods are commonly used to solve the UC problem. The main disadvantage of this group of methods is the difference between the dual and the primal solution which gives some significant problems on the quality of the feasible solution. In this paper, MSG method which does not require any convexity and differentiability assumptions is used for solving the UC problem. MSG method depending on the initial value reaches zero duality gap. SA algorithm is used in order to assign the appropriate initial value for MSG method. The major advantage of the proposed approach is that it guarantees the zero duality gap independently from the size of the problem. In order to show the advantages of this proposed approach, the four-unit Tuncbilek thermal plant and ten-unit thermal plant which is usually used in literature are chosen as test systems. Penalty function (PF method is also used to compare with our proposed method in terms of total cost and UC schedule.

    The integration of large-scale wind power adds a significant uncertainty to power system planning and operating. The wind forecast error is decreased with the forecast horizon, particularly when it is from one day to several hours ahead. Integrating intraday unit commitment (UC) adjustment process based on updated ultra-short term wind forecast information is one way to improve the dispatching results. A novel three-stage UC decision method, in which the day-ahead UC decisions are determined in the first stage, the intraday UC adjustment decisions of subfast start units are determined in the second stage, and the UC decisions of fast-start units and dispatching decisions are determined in the third stage is presented. Accordingly, a three-stage birandom UC model is presented, in which the intraday hours-ahead forecasted wind power is formulated as a birandom variable, and the intraday UC adjustment event is formulated as a birandom event. The equilibrium chance constraint is employed to ensure the reliability requirement. A birandom simulation based hybrid genetic algorithm is designed to solve the proposed model. Some computational results indicate that the proposed model provides UC decisions with lower expected total costs. PMID:24987739

    This paper presents a new method based on an immune-tabu hybrid algorithm to solve the thermal unit commitment (TUC) problem in power plant optimization. The mathematical model of the TUC problem is established by analyzing the generating units in modern power plants. A novel immune-tabu hybrid algorithm is proposed to solve this complex problem. In the algorithm, the objective function of the TUC problem is considered as an antigen and the solutions are considered as antibodies,which are determined by the affinity computation. The code length of an antibody is shortened by encoding the continuous operating time, and the optimum searching speed is improved. Each feasible individual in the immune algorithm (IA) is used as the initial solution of the tabu search (TS) algorithm after certain generations of IA iteration. As examples, the proposed method has been applied to several thermal unit systems for a period of 24 h. The computation results demonstrate the good global optimum searching performance of the proposed immune-tabu hybrid algorithm. The presented algorithm can also be used to solve other optimization problems in fields such as the chemical industry and the power industry.

    Full Text Available The unit commitment (UC problem which is an important subject in power system engineering is solved by using Lagragian relaxation (LR, penalty function (PF, and augmented Lagrangian penalty function (ALPF methods due to their higher solution quality and faster computational time than metaheuristic approaches. This problem is considered to be a nonlinear programming-(NP- hard problem because it is nonlinear, mixed-integer, and nonconvex. These three methods used for solving the problem are based on dual optimization techniques. ALPF method which combines the algorithmic aspects of both LR and PF methods is firstly used for solving the UC problem. These methods are compared to each other based on feasible schedule for each stage, feasible cost, dual cost, duality gap, duration time, and number of iterations. The numerical results show that the ALPF method gives the best duality gap, feasible and dual cost instead of worse duration time and the number of iterations. The four-unit Tuncbilek thermal plant which is located in Kutahya region in Turkey is chosen as a test system in this study. The programs used for all the analyses are coded and implemented using general algebraic modeling system (GAMS.

    This paper addresses the unit commitment (UC) in multi-period combined heat and power (CHP) production planning under the deregulated power market. In CHP plants (units), generation of heat and power follows joint characteristics, which implies that it is difficult to determine the relative cost...... efficiency of the plants. We introduce in this paper the DRDP-RSC algorithm, which is a dynamic regrouping based dynamic programming (DP) algorithm based on linear relaxation of the ON/OFF states of the units, sequential commitment of units in small groups. Relaxed states of the plants are used to reduce...... the dimension of the UC problem and dynamic regrouping is used to improve the solution quality. Numerical results based on real-life data sets show that this algorithm is efficient and optimal or near-optimal solutions with very small optimality gap are obtained....

    commitment model is proposed in this paper considering demand response and electric vehicles, which can promote the exploitation of wind power. On the one hand, demand response and electric vehicles have the feasi- bility to change the load demand curve to solve the mismatch problem. On the other hand......, they can serve as reserve for wind power. To deal with the unit commitment problem, authors use a fuzzy chance- constrained program that takes into account the wind power forecasting errors. The numerical study shows that the model can promote the utilization of wind power evidently, making the power...

    This paper studies the typical pattern of unit commitment (UC) results in terms of generator’s cost and capacity. A method is then proposed to combine a modified priority list technique with mixed integer linear programming (MILP) for UC problem. The proposed method consists of two steps. At the first step, a portion of generators are predetermined to be online or offline within a look-ahead period (e.g., a week), based on the demand curve and generator priority order. For the generators whose on/off status is predetermined, at the second step, the corresponding binary variables are removed from the UC MILP problem over the operational planning horizon (e.g., 24 hours). With a number of binary variables removed, the resulted problem can be solved much faster using the off-the-shelf MILP solvers, based on the branch-and-bound algorithm. In the modified priority list method, scale factors are designed to adjust the tradeoff between solution speed and level of optimality. It is found that the proposed method can significantly speed up the UC problem with minor compromise in optimality by selecting appropriate scale factors.

    Long-range cis-regulatory elements such as enhancers coordinate cell-specific transcriptional programmes by engaging in DNA looping interactions with target promoters. Deciphering the interplay between the promoter connectivity and activity of cis-regulatory elements during lineage commitment is crucial for understanding developmental transcriptional control. Here, we use Promoter Capture Hi-C to generate a high-resolution atlas of chromosomal interactions involving ~22,000 gene promoters in human pluripotent and lineage-committed cells, identifying putative target genes for known and predicted enhancer elements. We reveal extensive dynamics of cis-regulatory contacts upon lineage commitment, including the acquisition and loss of promoter interactions. This spatial rewiring occurs preferentially with predicted changes in the activity of cis-regulatory elements and is associated with changes in target gene expression. Our results provide a global and integrated view of promoter interactome dynamics during lineage commitment of human pluripotent cells.

    This paper presents a new approach for GenCos Profit Based Unit Commitment (GPBUC) in day-ahead competitive electricity markets. Generation, spinning and non-spinning reserves are considered in the proposed formulation. The estimated probability that spinning and non-spinning reserves are called and generated is also considered in the formulation to simulate the reserve uncertainty. The artificial neural network (ANN) is applied for forecasting the reserve probability considering line limits, line and generator outages, market prices, bidding strategy, load and reserves patterns. Fuel and emission constraints are included in the model. A hybrid method between Lagrangian relaxation (LR) and evolutionary programming (EP) is applied to solve the proposed GPBUC problem. The proposed approach is applied to a 36 unit test system and the results are compared with those obtained from other approaches. (author)

  12. Two-Stage Robust Security-Constrained Unit Commitment with Optimizable Interval of Uncertain Wind Power Output

    Directory of Open Access Journals (Sweden)

    Dayan Sun

    2017-01-01

    Full Text Available Because wind power spillage is barely considered, the existing robust unit commitment cannot accurately analyze the impacts of wind power accommodation on on/off schedules and spinning reserve requirements of conventional generators and cannot consider the network security limits. In this regard, a novel double-level robust security-constrained unit commitment formulation with optimizable interval of uncertain wind power output is firstly proposed in this paper to obtain allowable interval solutions for wind power generation and provide the optimal schedules for conventional generators to cope with the uncertainty in wind power generation. The proposed double-level model is difficult to be solved because of the invalid dual transform in solution process caused by the coupling relation between the discrete and continuous variables. Therefore, a two-stage iterative solution method based on Benders Decomposition is also presented. The proposed double-level model is transformed into a single-level and two-stage robust interval unit commitment model by eliminating the coupling relation, and then this two-stage model can be solved by Benders Decomposition iteratively. Simulation studies on a modified IEEE 26-generator reliability test system connected to a wind farm are conducted to verify the effectiveness and advantages of the proposed model and solution method.

    The three-component model of organization commitment has typically been studied using a variable-centered rather than a person-centered approach, preventing a more complete understanding of how these forms of commitment are felt and expressed as a whole. Latent profile analysis was used to identify qualitatively distinct categories or profiles of staff nurses' commitment. Then, associations of the profiles with perceived work unit relations and turnover intentions were examined. Three hundred thirty-six registered nurses provided data on affective, normative, and continuance commitment, perceived work unit relations, and turnover intentions. Latent profile analysis of the nurses' commitment scores revealed six distinct profile groups. Work unit relations and turnover intentions were compared in the six profile-defined groups. Staff nurses with profiles characterized by high affective commitment and/or high normative commitment in relation to other components experienced stronger work unit relations and reported lower turnover intentions. Profiles characterized by high continuance commitment relative to other components or by low overall commitment experienced poorer work unit relations, and the turnover risk was higher. High continuance commitment in combination with high affective and normative commitment was experienced differently than high continuance commitment in combination with low affective and normative commitment. Healthcare organizations often foster commitment by using continuance commitment-enhancing strategies (e.g., offer high salaries and attractive benefits) that may inadvertently introduce behavioral risk. This work suggests the importance of changing the context in which continuance commitment occurs by strengthening the other two components.

    2014-10-01

    Wildlife planning for renewable energy must cope with the uncertainties of potential wildlife impacts. Unfortunately, the environmental policies which instigate renewable energy and those which protect wildlife are not coherently aligned-creating a green versus green dilemma. Thus, climate mitigation efforts trigger renewable energy development, but then face substantial barriers from biodiversity protection instruments and practices. This article briefly reviews wind energy and wildlife interactions, highlighting the lively debated effects on bats. Today, planning and siting of renewable energy are guided by the precautionary principle in an attempt to carefully address wildlife challenges. However, this planning attitude creates limitations as it struggles to negotiate the aforementioned green versus green dilemma. More adaptive planning and management strategies and practices hold the potential to reconcile these discrepancies to some degree. This adaptive approach is discussed using facets of case studies from policy, planning, siting, and operational stages of wind energy in Germany and the United States, with one case showing adaptive planning in action for solar energy as well. This article attempts to highlight the benefits of more adaptive approaches as well as the possible shortcomings, such as reduced planning security for renewable energy developers. In conclusion, these studies show that adaptive planning and operation strategies can be designed to supplement and enhance the precautionary principle in wildlife planning for green energy.

    The purpose of this descriptive correlational study was to investigate the relationship between commitments, uncertainty about the cancer situation, threat of recurrence, and control of the cancer situation and the set of coping strategies used by women to cope with their breast cancer diagnosis. Lazarus and Folkman's theory of psychological stress provided the framework. The sample consisted of 227 nonhospitalized women who had had a diagnosis of breast cancer. Two sets of canonical variate sets were significant at the .001 level with canonical correlations of .52 and .47. The first canonical set indicated that the use of escape-avoidance and accepting responsibility but not positive reappraisal strategies were characteristics of those women who had low commitment and low control together with high uncertainty and high threat of recurrence. The second set indicated that seeking social support, as well as the use of planful problem solving, escape-avoidance, positive reappraisal, and self-controlling strategies was adopted by women who had high threat of recurrence and high control.

  18. A Multi-Objective Unit Commitment Model for Setting Carbon Tax to Reduce CO2 Emission: Thailand's Electricity Generation Case

    2015-07-01

    Full Text Available Carbon tax policy is a cost-effective instrument for emission reduction. However, setting the carbon tax is one of the challenging task for policy makers as it will lead to higher price of emission-intensive sources especially the utility price. In a large-scale power generation system, minimizing the operational cost and the environmental impact are conflicting objectives and it is difficult to find the compromise solution. This paper proposes a methodology of finding a feasible carbon tax rate on strategic level using the operational unit commitment model. We present a multi-objective mixed integer linear programming model to solve the unit commitment problem and consider the environmental impacts. The methodology of analyzing of the effect of carbon tax rates on the power generation, operating cost, and CO2 emission is also provided. The trade-off relationship between total operating cost and total CO2 emission is presented in the Pareto-optimal curve to analyze the feasible carbon tax rate that is influencing on electricity operating cost. The significant outcome of this paper is a modeling framework for the policy makers to determine the possible carbon tax that can be imposed on the electricity generation.

    2014-08-01

    Full Text Available This paper seeks to understand the rationale behind the practice of remittances and to examine its impact on the living standards and conditions of Ghanaian remitters living in Amsterdam, the Netherlands. This study investigates how remitters are able to sustain their lifestyles in a foreign country, and the sacrifices and compromises made in terms of their dual commitment to support families in Ghana and in the Netherlands. A qualitative approach using in-depth interviews was adopted in order to give research participants an opportunity to talk broadly about their lived experiences as Ghanaians residing in a foreign country and the challenges associated with sending remittances. Push factors such as political unrest, poverty, low income, and unemployment influenced movement out of Ghana. A better quality of life (better paying jobs, improved qualifications was the major pull factor that attracted migrants to the Netherlands. Remittances from migrants in the Netherlands supported the welfare of many households in Ghana, especially in terms of improved standards of living and better access to health care and education. Sending remittances is not “a feel good gesture” only, but an obligation to the family members back in Ghana. This study shows that there were major compromises and trade-offs in terms of migrant lifestyles because of their dual commitments.

    Ineffective inpatient discharge planning often causes discharge delays and upstream boarding. While an optimal discharge strategy that works across all units at a hospital is likely difficult to identify and implement, a strategy that provides a reasonable target to the discharge team appears feasible. We used observational and retrospective data from an inpatient trauma unit at a Level 2 trauma center in the Midwest US. Our proposed novel n-by-T strategy-discharge n patients by the Tth hour-was evaluated using a validated simulation model. Outcome measures included 2 measures: time-based (mean discharge completion and upstream boarding times) and capacity-based (increase in annual inpatient and upstream bed hours). Data from the pilot implementation of a 2-by-12 strategy at the unit was obtained and analyzed. The model suggested that the 1-by-T and 2-by-T strategies could advance the mean completion times by over 1.38 and 2.72 h, respectively (for 10 AM ≤ T ≤ noon, occupancy rate = 85%); the corresponding mean boarding time reductions were nearly 11% and 15%. These strategies could increase the availability of annual inpatient and upstream bed hours by at least 2,469 and 500, respectively. At 100% occupancy rate, the hospital-favored 2-by-12 strategy reduced the mean boarding time by 26.1%. A pilot implementation of the 2-by-12 strategy at the unit corroborated with the model findings: a 1.98-h advancement in completion times (Pstrategies, such as the n-by-T, can help substantially reduce discharge lateness and upstream boarding, especially during high unit occupancy. To sustain implementation, necessary commitment from the unit staff and physicians is vital, and may require some training.

    2016-05-01

    Energy storage systems (ESSs) have experienced a very rapid growth in recent years and are expected to be a promising tool in order to improving power system reliability and being economically efficient. The ESSs possess many potential benefits in various areas in the electric power systems. One of the main benefits of an ESS, especially a bulk unit, relies on smoothing the load pattern by decreasing on-peak and increasing off-peak loads, known as load leveling. These devices require new methods and tools in order to model and optimize their effects in the power system studies. In this respect, this paper will model bulk ESSs based on the several technical characteristics, introduce the proposed model in the thermal unit commitment (UC) problem, and analyze it with respect to the various sensitive parameters. The technical limitations of the thermal units and transmission network constraints are also considered in the model. The proposed model is a Mixed Integer Linear Programming (MILP) which can be easily solved by strong commercial solvers (for instance CPLEX) and it is appropriate to be used in the practical large scale networks. The results of implementing the proposed model on a test system reveal that proper load leveling through optimum storage scheduling leads to considerable operation cost reduction with respect to the storage system characteristics.

    2012-01-01

    Full Text Available One of the necessary actions in many organizations is to reduce the number of workers in an attempt to restructure business activities. However, layoff could have negative consequences since many employees may decide to leave since they lose their tolerance. The layoff must be accompanied with some supportive plans to reduce stress among the remaining workers and increase their commitment for long-term work. The present study of this paper considers the effects of layoff on job satisfaction and commitment among the remaining employees of a detergent producer unit. The results indicate that a good supportive program including wage increase, family support, health care plans, etc. could significantly improve employee long-term commitments and it leads to job satisfaction.

    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.

    This paper gives an overview of the National Aeronautics and Space Administration (NASA) led multi-center Habitat Demonstration Unit (HDU) project leadership and management strategies. The HDU project team constructed and tested an analog prototype lunar surface habitat/laboratory called the Pressurized Excursion Module (PEM) during 2010. The prototype unit subsystems were integrated in a short amount of time, utilizing a tiger team approach that brought together over 20 habitation-related technologies and innovations from a variety of NASA centers. This paper describes the leadership and management strategies as well as lessons learned pertaining to leading and managing a multi-center diverse team in a rapid prototype environment. The PEM configuration went from a paper design to an operational surface habitat demonstration unit in less than 12 months. The HDU project is part of the strategic plan from the Exploration Systems Mission Directorate (ESMD) Directorate Integration Office (DIO) and the Exploration Mission Systems Office (EMSO) to test destination elements in analog environments. The 2011 HDU-Deep Space Habitat (DSH) configuration will build upon the PEM work, and emphasize validity of crew operations (remote working and living), EVA operations, mission operations, logistics operations, and science operations that might be required in a deep space context for Near Earth Object (NEO) exploration mission architectures. The 2011 HDU-DSH will be field-tested during the 2011 Desert Research and Technologies Studies (DRaTS) field tests. The HDU project is a "technology-pull" project that integrates technologies and innovations from multiple NASA centers. This project will repurpose the HDU 2010 demo unit that was field tested in the 2010 DRaTS, adding habitation functionality to the prototype unit. This paper will describe the strategy of establishing a multi-center project management team that put in place the key multi-center leadership skills and

    With the parallel development of distributed generation technology and large power grid technology, a great amount of renewable energy generation was introduced to the electrical power grid. Under this circumstance, a unit commitment model was established by considering the constraints of transmission safety using AC (alternating current) power flow. This model also involved reactive and voltage constraints, as well as safe operation limits of generators. According to the Benders decomposition, the model was decomposed into a master problem and a sub-problem. The master problem could solve the unit commitment without AC constraints, and then the sub-problem could check the AC constraints according to the result of the master problem. Benders cuts might develop from the sub problem, and the cuts would form additional associated constraints, which could connect the master problem and the sub problem. Simulation results of modified IEEE-14 buses case proved that the proposed method could effectively solve unit commitment problems with constraints of AC power flow.%针对当前大电网与分布式发电并进,可再生资源发电大量接入的电网发展格局,构建交流潮流约束下的机组组合模型,在传统考虑有功网络安全约束的基础上,引入无功电压的制约,并计及机组的安全运行极限。依据Benders分解思想,将该模型分解为主、子两个问题,主问题为单母线模型机组组合,子问题为交流潮流约束的检验,通过子问题导引的Benders割形成主、子问题之间关联的附加约束。修正的IEEE-14节点仿真结果表明,该方法能够有效解决交流潮流约束下的机组组合问题。

    Delirium is an acute brain dysfunction associated with poor outcomes in intensive care unit (ICU) patients. Critical care nurses play an important role in the prevention, detection, and management of delirium, but they must be able to accurately assess for it. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) instrument is a reliable and valid method to assess for delirium, but research reveals most nurses need practice to use it proficiently. A pretest-posttest design was used to evaluate the success of a multimodal educational strategy (i.e., online learning module coupled with standardized patient simulation experience) on critical care nurses' knowledge and confidence to assess and manage delirium using the CAM-ICU. Participants (N = 34) showed a significant increase (p assess and manage delirium following the multimodal education. No statistical change in knowledge of delirium existed following the education. A multimodal educational strategy, which included simulation, significantly added confidence in critical care nurses' performance using the CAM-ICU. J Contin Nurs Educ. 2017;48(5):239-244.

    The German Federal Government published its energy concept in September 2010 with a description of the road into the era of renewable energies. Therefore, the future renewable energy installed in Germany is expected to consist mostly of wind and solar, which are subject to intermittency of supply and significant fluctuations. The growing portion of energy generation by fluctuating sources is turning to a big challenge for the power plant unit commitment and the investment decisions as well. In this thesis, a fundamental electricity market model with combined modeling of these two aspects is developed. This model is subsequently applied to the German electricity market to investigate what kind of power plant investments are indispensable, considering the steadily increasing portion of energy generation from fluctuating sources, to ensure a reliable energy supply in a cost-effective way in the future. In addition, current energy policy in Germany regarding the use of renewable energy and nuclear energy is analyzed.

The performance of the algorithm is improved by introducing a new method to generate the initial population, a new mutation operator, and a local search operator. Based on numerical examples, test results show the feasibility of the mathematical model of the SUC problem and its improved GA-based solution method.

    Applied behavior analysts work with many populations including individuals with developmental and intellectual disabilities. Although behavior analysts have a variety of empirically supported treatments to implement when working with individuals with disabilities, sometimes, other variables may adversely impact treatment effectiveness. The degree to which problematic thoughts and feelings (private events) influence behavior may be a variable that contributes to treatment efficacy. Traditional behavior analytic services are not always equipped to successfully address the private events influencing client behavior. In such cases, it may be beneficial for behavior analysts to consider additional philosophically aligned treatments for private events. One such treatment, acceptance and commitment therapy, may be a useful tool for behavior analysts to incorporate into their toolbox in order to help clients. The purpose of this paper is to introduce behavior analysts to a potential solution to the problem of effectively addressing private events in behavior analytic services. We then propose a model for thinking about private events in relation to clients with disabilities and present a guide for taking steps to address private events in the clinical setting. We conclude this paper with a call for research and present a possible research agenda for behavior analysts.

      为了解决风电的随机波动性给含大规模风电场电力系统机组组合问题求解带来的影响,采用马尔科夫链原理描述风速变化的规律,并将它与场景树技术相结合,对风电的不确定性进行数学建模。同时基于机会约束规划建立了含风电场机组组合问题的随机数学模型,包含外层机组启停状态优化和内层机组间负荷经济分配两层优化子问题。在求解模型时,将离散粒子群算法(DPSO)与等微增率准则相结合,对两层优化问题进行交替迭代求解;同时提出开停机调整策略改善解的特性。对一个含风电场的10常规机组系统进行算例分析,验证了所提出数学模型和求解方法的合理性和有效性。%In order to cope with the difficulties brought by the volatile and intermittent nature of wind power when solving the unit commitment problem with large-scale wind farms, the basic principles of Markov chain are adopted to describe the regularity of the change of wind speed, and used to model the uncertainty of wind power combining with scenario tree. And this paper presents a stochastic programming model based on chance-constrained programming, and the unit commitment problem is decomposed into two embedded optimization sub-problems: the unit on/off status schedule problem and the load economic dispatch problem. The two problems are solved alternately and iteratively by discrete particle swarm optimization (DPSO) and the equal incremental principle, and an adjusted strategy of units’ on/off status enhances the algorithm’s optimization performance. The results on a system with 10 thermal units and wind farms demonstrate the feasibility and effectiveness of the proposed model and algorithm.

    2009-09-01

    This study aims to identify strategies for safe medication use practices in ambulatory care settings, with a special focus on clinical pharmacy services. We conducted case studies on 34 organizations, more than half of which were safety net providers. Data included discussions with 186 key informants, 3 interim debriefings, and a technical expert panel. We analyzed qualitative data using inductive analysis techniques and grounded theory approach. Ambulatory care organizations practice a broad range of safe medication use strategies. The inclusion of clinical pharmacy services is a culture change that supports efforts to improve patient safety and patient-centered care. Organizations integrated clinical pharmacy services when they introduced such services in a purposefully paced and gradual manner. Organizations sustained such services when they collected and reported data demonstrating improvements in patient outcomes and cost savings. Clinical pharmacy services were generally accompanied by strategies that helped organizations to provide patient-centered care; collect and measure process, safety, and clinical outcomes; promote leadership commitment; and integrate care delivery processes. These strategies interacted within organizations in synergistic rather than hierarchical or linear way. Organizational ability to provide safe, patient-centered, and efficient care that is supported by measurable data largely depends on leadership commitment and ability to integrate care processes. Ambulatory care organizations use multiple strategies for safe medication use systems. Understanding processes that promote such strategies will provide a helpful road map for other organizations in implementation and sustainability of safe medication use systems.

    Full Text Available Abstract Background We aimed to determine optimal strategies for complete mortality ascertainment comparing death certificates and United States (US Veterans Administration (VA records. Methods We constructed a cohort of California veterans who died in fiscal year (FY 2000 and used VA services the year before death. We determined decedent status using California death certificates linked to VA utilization data and the VA Beneficiary Identification and Records Locator System (BIRLS death file. We compared the characteristics of decedents who would not have been identified by either single source (e.g., VA BIRLS alone or California death certificates alone with the rest of the cohort. Results A total of 8,813 veteran decedents were identified from both VA decedent files and death certificates. Of all decedents, 5,698 / 8,813 (65% veterans were identified in both source files, but 2,426 / 8,813 (28% decedents were not identified in VA BIRLS, and 689 / 8,813 (8% were not identified in death certificates. Compared to the rest of the cohort, decedents whose mortality status was ascertained through either single source differed by race / ethnicity, marital status, and California residence. Clinically, veterans identified from either single source had less comorbidity and were less likely to have been users of VA inpatient or long term care, but equally or more likely to have been users of VA outpatient services. Conclusion As single sources, VA decedent files and death certificates each provided an incomplete record, and death ascertainment was improved by using both source files. Potential bias may vary depending on analytic interest.

The objective function of the unit commitment is non-analytic. This paper presents the mathematical model of the unit commitment based on SMP with a new method for solving the unit commitment by analyzing the mechanism of the Lagrangian relaxation method and its coordinating process. The method overcomes the “calculated oscillation” and “dead-zone regulation” problems arising from the analysis of the unit commitment in a deregulated environment by traditional methods. The quick convergence and excellent optimizing ability of the new method are demonstrated by a practical application.

    Ahmed, Aziza; Hanssens, Catherine; Kelly, Brook

    2009-11-01

    To bring the United States in line with prevailing human rights standards, its National HIV/AIDS Strategy will need to explicitly commit to a human rights framework when developing programmes and policies that serve the unaddressed needs of women. This paper focuses on two aspects of the institutionalized mistreatment of people with HIV: 1) the criminalization of their consensual sexual conduct; and 2) the elimination of informed and documented consensual participation in their diagnosis through reliance on mandatory and opt-out testing policies. More than half of US states have HIV-specific laws criminalizing the consensual sexual activity of people with HIV, regardless of whether transmission occurs. Many of these laws hinge prosecution on the failure of HIV-positive people to disclose their HIV status to a sexual partner. The Obama Administration should explore administrative and legislative incentives to eliminate these laws and prosecutions, and target a portion of prevention funding for anti-stigma training. Testing policies should be reconsidered to remove opt-out and/or mandatory HIV testing as a condition for receipt of federal funding; incentives should encourage states to adopt local policies mandating counseling; and voluntary HIV testing should be offered regardless of the provider's undocumented perception of an individual's risk.

    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.

    Antiretroviral treatment has transformed HIV from a death sentence to a chronic condition, allowing people with HIV to live longer and healthier lives. However, they face significant barriers to accessing and affording life-saving-but expensive-antiretroviral (ARV) medications. These barriers are particularly severe for low-income patients, and they disproportionately affect racial and ethnic minorities. High ARV prices create pressure for government insurers to contain costs either by rationing care or by restricting eligibility for public programs. Limited funding, coupled with a growing demand for HIV care and treatment, is likely to make programmatic decisions about who is covered become more difficult over time. Therefore, it is important to identify options for reducing the cost of providing ARVs to allow more people to receive treatment. This study examines a variety of options for negotiating lower ARV procurement costs in U.S. markets. A case-study approach is used to assess options that different stakeholders could use in negotiating ARV price discounts with drug manufacturers given the regulatory and market constraints that exist in the United States.

    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.

    2012-03-01

    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.

    Missed injuries sustain an important issue concerning patient safety and quality of care. The purpose of this study is to examine the effect of surgeon commitment to trauma care on missed injuries. We hypothesised that surgeons committed to the trauma service has less missed injuries than surgeons not committed to the trauma service would have. By retrospective analysis of 976 adult patients admitted to the trauma intensive care unit (ICU) at an urban, university-based trauma centre. Missed injuries were compared between two groups; in group 1 the patients were evaluated and treated by the surgeons who were committed to the trauma service and in group 2 the patients were evaluated and treated by surgeons practicing mainly in other specialties. Patients had significantly lower rates of missed major or life-threatening injuries when treated by group 1 surgeons. Logistic regression model revealed significant factors associated with missed major or life-threatening injuries including ISS and groups in which patients were treated by different group surgeons. Physicians will perform better when they are trained and interested in a specific area than those not trained, or even not having any particular interest in that specific area. Surgeons committed to the trauma service had less missed injuries in severely injured patients, and it is vital to improve patient safety and quality of care for trauma patients. Staff training and education for assessing severely injured patients and creating an open culture with detection and reduction of the potential for error are important and effective strategies in decreasing missed injuries and improving patient safety.

  20. Managing by commitments.

    Science.gov (United States)

    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?

  1. 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...

    The recently (2013) identified pathogenic chytrid fungus, Batrachochytrium salamandrivorans (Bsal), poses a severe threat to the distribution and abundance of salamanders within the United States and Europe. Development of a response strategy for the potential, and likely, invasion of Bsal into the United States is crucial to protect global salamander biodiversity. A formal working group, led by Amphibian Research and Monitoring Initiative (ARMI) scientists from the U.S. Geological Survey (USGS) Patuxent Wildlife Research Center, Fort Collins Science Center, and Forest and Rangeland Ecosystem Science Center, was held at the USGS Powell Center for Analysis and Synthesis in Fort Collins, Colorado, United States from June 23 to June 25, 2015, to identify crucial Bsal research and monitoring needs that could inform conservation and management strategies for salamanders in the United States. Key findings of the workshop included the following: (1) the introduction of Bsal into the United States is highly probable, if not inevitable, thus requiring development of immediate short-term and long-term intervention strategies to prevent Bsal establishment and biodiversity decline; (2) management actions targeted towards pathogen containment may be ineffective in reducing the long-term spread of Bsal throughout the United States; and (3) early detection of Bsal through surveillance at key amphibian import locations, among high-risk wild populations, and through analysis of archived samples is necessary for developing management responses. Top research priorities during the preinvasion stage included the following: (1) deployment of qualified diagnostic methods for Bsal and establishment of standardized laboratory practices, (2) assessment of susceptibility for amphibian hosts (including anurans), and (3) development and evaluation of short- and long-term pathogen intervention and management strategies. Several outcomes were achieved during the workshop, including development

    To identify and assess strategies for evaluating the impact of mobile eye health units on health outcomes. Systematic literature review. Worldwide. Peer-reviewed journal articles that included the use of a mobile eye health unit. Journal articles were included if outcome measures reflected an assessment of the impact of a mobile eye health unit on health outcomes. Six studies were identified with mobile services offering diabetic retinopathy screening (three studies), optometric services (two studies) and orthoptic services (one study). This review identified and assessed strategies in existing literature used to evaluate the impact of mobile eye health units on health outcomes. Studies included in this review used patient outcomes (i.e. disease detection, vision impairment, treatment compliance) and/or service delivery outcomes (i.e. cost per attendance, hospital transport use, inappropriate referrals, time from diabetic retinopathy photography to treatment) to evaluate the impact of mobile eye health units. Limitations include difficulty proving causation of specific outcome measures and the overall shortage of impact evaluation studies.

    In accordance with the characteristics of the unit commitment problem in marine power system, we propose an improved genetic algorithm with-both float-point coding and binary coding. To apply the nonlinear 0-1 mixed integer programming to the optimization of the unit commitment, other items in the algorithm are modified accordingly, including the coding and decoding modes, initial population creation, constraint conditions disposal, fitness function selection, genetic operators and the control parameters modulation. In the application of this improved algorithm, not only the constraint conditions can be handled more readily, but the convergence speed and the solution precision are also improved. The application advantage is demonstrated by a 2% reduction in average oil consumption rate.%针对某舰用电站机组负荷组合的特点,提出了一种基于浮点数和二进制数统一编码的改进遗传算法,并进一步对算法中的编码解码方式、初始种群生成、约束条件处理、遗传算子映射及控制参数调节等作了改进,解决了机组优化组合的0-l混合整数非线性规划问题.改进后的算法不仅较好地处理了机组优化组合中的各种约束条件,同时改善了算法的收敛性.优化结果表明机组油耗率降幅最大可达2%,效果显著.

This can be accomplished by assessing the upper and lower limit of charging load of each EV aggregator based on the grid connected EVs scenarios simulation using Monte Carlo method. A unit commitment (UC) model is proposed for optimal coordination of wind power generation and charging load of EV aggregators. Cases study show that with the proposed UC model the wind abandon can be decreased as well as the cost of operation effectively.

  11. A new look at the science of weight control: how acceptance and commitment strategies can address the challenge of self-regulation.

    Science.gov (United States)

    Forman, Evan M; Butryn, Meghan L

    2015-01-01

    The current manuscript proposes an acceptance-based, self-regulation framework for understanding the challenge of weight maintenance and describes how this framework can be integrated into the behavioral treatment of obesity. According to this framework, intrinsic drives to consume palatable, high-calorie food interact with a modern environment in which high calorie foods are easily accessible. This combination produces a chronic desire to eat unhealthy foods that exists in opposition to individuals' weight control goals. Similarly, low energy expenditure requirements reduce physical activity. We suggest that individuals vary in their responsivity to cues that motivate overeating and sedentary behavior, and that those higher in responsivity need specialized self-regulatory skills to maintain healthy eating and exercise behaviors. These skills include an ability to tolerate uncomfortable internal reactions to triggers and a reduction of pleasure, behavioral commitment to clearly-defined values, and metacognitive awareness of decision-making processes. So-called "acceptance-based" interventions based on these skills have so far proven efficacious for weight control, especially for those who are the most susceptible to eating in response to internal and external cues (as predicted by the model). Despite the current empirical support for the postulated model, much remains to be learned including whether acceptance-based interventions will prove efficacious in the longer-term.

  17. Fault detection and diagnosis of control strategies for air-handling units

    The most common method used for Fault Detection and Diagnosis (FDD) in building control systems involves margin testing of measured signals, where the signals are compared with predefined upper and lower thresholds. In order to avoid damage to heating, ventilation and air conditioning (HVAC) systems, the threshold is often reduced so there is enough time to adopt counter-measures. This can lead to more frequent alarms and malfunction reports. Process monitoring observes the functionality of every component of the entire HVAC system. However, the faults of control strategies tend to remain unknown and undetected. This paper discussed the development of a novel mathematical model based on linear algebra systems for FDD of control systems for Air-Handling Units (AHU), in relation to the psychometric processes governed by the investigated AHU control strategy from outside air to supply air. It was noted that there are usually 2 controlled variables in AHU: temperature and humidity. FDD concepts for conventional AHU units were examined, as well as units using desiccant evaporative cooling technology. The approach allowed for an analysis of the psychometric processes associated with each AHU component based on benchmark calculations provided by the building simulation program TRYNSYS, and facilitated a quantitative assessment of the thermodynamic efficiency of the HVAC process in the AHU as governed by the investigated control strategy. It was concluded that the proposed FDD concept enabled detection and diagnosis of possible faults in control strategies for AHU in the design phase, as well as allowing for the development of improved AHU control sequences. In addition, the proposed FDD method allowed for the evaluation of control strategies in existing HVAC systems. It was suggested that the FDD of existing AHU control sequences will require the availability of measured values of inlet and outlet air properties of every AHU component. 17 refs., 12 figs.

    To improve the transient stability ofmultimachine power systems,observational linearization and tracking objective excitation control laws were derived from the phasor measurement unit (PMU),observational linearization,and tracking objective control theory based on synchronized coordinates and reference generator coordinates.The control strategies utilized real-time state variables obtained by PMU to linearize the state equations of the system,and then the linear optimal control strategy was used to design excitation controllers.The inaccuracy of the local linearization method and the complexity of the system models designed in the exact linearization method for nonlinear systems were avoided.Therefore,the control strategies were applied in real time.Simulation results show that the proposed method can improve the transient stability of power systems more efficiently than nonlinear optimal excitation control.

    Dynamic fluorescence molecular tomography (DFMT) is a valuable method to evaluate the metabolic process of contrast agents in different organs in vivo, and direct reconstruction methods can improve the temporal resolution of DFMT. However, challenges still remain due to the large time consumption of the direct reconstruction methods. An acceleration strategy using graphics processing units (GPU) is presented. The procedure of conjugate gradient optimization in the direct reconstruction method is programmed using the compute unified device architecture and then accelerated on GPU. Numerical simulations and in vivo experiments are performed to validate the feasibility of the strategy. The results demonstrate that, compared with the traditional method, the proposed strategy can reduce the time consumption by ˜90% without a degradation of quality.

  20. Evaluating Infection Prevention Strategies in Out-Patient Dialysis Units Using Agent-Based Modeling.

    Directory of Open Access Journals (Sweden)

    Joanna R Wares

    Full Text Available Patients receiving chronic hemodialysis (CHD are among the most vulnerable to infections caused by multidrug-resistant organisms (MDRO, which are associated with high rates of morbidity and mortality. Current guidelines to reduce transmission of MDRO in the out-patient dialysis unit are targeted at patients considered to be high-risk for transmitting these organisms: those with infected skin wounds not contained by a dressing, or those with fecal incontinence or uncontrolled diarrhea. Here, we hypothesize that targeting patients receiving antimicrobial treatment would more effectively reduce transmission and acquisition of MDRO. We also hypothesize that environmental contamination plays a role in the dissemination of MDRO in the dialysis unit. To address our hypotheses, we built an agent-based model to simulate different treatment strategies in a dialysis unit. Our results suggest that reducing antimicrobial treatment, either by reducing the number of patients receiving treatment or by reducing the duration of the treatment, markedly reduces overall colonization rates and also the levels of environmental contamination in the dialysis unit. Our results also suggest that improving the environmental decontamination efficacy between patient dialysis treatments is an effective method for reducing colonization and contamination rates. These findings have important implications for the development and implementation of future infection prevention strategies.

Delirium increases treatment costs because of treatment delays, prolonged hospital stays and other associated complications. Despite all those problems associated with delirium, a systemic prevention strategy does not exist yet. This study used an economic evaluation design by reviewing relevant medical records. Study objects were 130 patients who were admitted to the ICU after liver transplantation surgery. After looking at the medical records of these patients, we divided them into two groups according to the application of the prevention strategy. This study analysed the costs and benefits of the prevention strategy between the groups. The prevalence rate of delirium was 35·3% in the prevention-care group and 51·6% in the usual-care group. A sum of $38·4 was invested for the prevention strategy in opposite to the expected total costs of $5578 for a probable treatment. Thus, the net benefit was $5539·6 with a benefit ratio of 145·3 CONCLUSIONS: A strategy is necessary for the delirium prevention of patients in the ICU to decrease the economic burden. This study demonstrated that a prevention strategy was cost-effective because of its low input costs. With low additional investment, it is expected that this prevention strategy will be more available to other patients in the future. © 2014 British Association of Critical Care Nurses.

  3. Investment and Consumption without Commitment

    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 paper describes a class of strategies for reducing persistent contrail formation in the United States airspace. The primary objective is to minimize potential contrail formation regions by altering the aircraft's cruising altitude in a fuel-efficient way. The results show that the contrail formations can be reduced significantly without extra fuel consumption and without adversely affecting congestion in the airspace. The contrail formations can be further reduced by using extra fuel. For the day tested, the maximal reduction strategy has a 53% contrail reduction rate. The most fuel-efficient strategy has an 8% reduction rate with 2.86% less fuel-burnt compared to the maximal reduction strategy. Using a cost function which penalizes extra fuel consumed while maximizing the amount of contrail reduction provides a flexible way to trade off between contrail reduction and fuel consumption. It can achieve a 35% contrail reduction rate with only 0.23% extra fuel consumption. The proposed fuel-efficient contrail reduction strategy provides a solution to reduce aviation-induced environmental impact on a daily basis.

    2006-01-01

    To monopolize the scientific data gained by Japanese physicians and researchers from vivisections and other barbarous experiments performed on living humans in biological warfare programs such as Unit 731, immediately after the war the United States (US) government secretly granted those involved immunity from war crimes prosecution, withdrew vital information from the International Military Tribunal for the Far East, and publicly denounced otherwise irrefutable evidence from other sources such as the Russian Khabarovsk trial. Acting in "the national interest" and for the security of the US, authorities in the US tramped justice and morality, and engaged in what the English common law tradition clearly defines as "complicity after the fact." To repair this historical injustice, the US government should issue an official apology and offer appropriate compensation for having covered up Japanese medical war crimes for six decades. To help prevent similar acts of aiding principal offender(s) in the future, international declarations or codes of human rights and medical ethics should include a clause banning any kind of complicity in any unethical medicine-whether before or after the fact-by any state or group for whatever reasons.

    The purpose of this study was to explore the strategies used by nurse managers in Japan to facilitate the integration of newly graduate nurses (NGNs) into their clinical units. The integration of NGNs into clinical units is an important issue for both NGNs and nurse managers because the first year of practice plays a vital role in a NGN's career. Data were generated through semi-structured interviews with 9 nurse managers in 9 acute care hospitals. Data analysis was conducted using a qualitative content analysis method. Nurse managers used a total of 6 strategies: understanding the circumstances of NGNs, providing opportunities for experience and learning, supporting nurses who teach NGNs, facilitating self-learning, promoting awareness of being a nurse in the clinical unit, and strengthening the sense of comradeship in clinical units. Three of these strategies were particularly important for NGNs' integration into clinical units: facilitating self-learning, promoting awareness of being a nurse in the clinical unit, and strengthening the sense of comradeship in clinical units. These strategies were described in this study. The strategies adopted by nurse managers should be aimed at all nurses, not just NGNs, in order to strengthen the sense of comradeship in clinical units. This approach would create a supportive environment for the integration of NGNs into clinical units. The strategies presented in this study can be utilized not just by nurse managers but all senior nurses in the unit. NGNs can use these strategies to help them understand what they need to do to become a full member of their unit.

    This paper gives an overview of the National Aeronautics and Space Administration (NASA) led multi-center Habitat Demonstration Unit (HDU) project leadership and management strategies being used by the NASA HDU team for a rapid prototyping project. The HDU project team constructed and tested an analog prototype lunar surface habitat/laboratory called the Pressurized Excursion Module (PEM) during 2010. The prototype unit subsystems were integrated in a short amount of time, utilizing a tiger team rapid prototyping approach that brought together over 20 habitation-related technologies and innovations from a variety of NASA centers. This paper describes the leadership and management strategies as well as lessons learned pertaining to leading and managing a multi-center diverse team in a rapid prototype environment. The PEM configuration went from a paper design to an operational surface habitat demonstration unit in less than 12 months. The HDU project is part of the strategic plan from the Exploration Systems Mission Directorate (ESMD) Directorate Integration Office (DIO) and the Exploration Mission Systems Office (EMSO) to test destination elements in analog environments. The 2011 HDU-Deep Space Habitat (DSH) configuration will build upon the PEM work, and emphasize validity of crew operations (remote working and living), EVA operations, mission operations, logistics operations, and science operations that might be required in a deep space context for Near Earth Object (NEO) exploration mission architectures. The 2011 HDU-DSH will be field-tested during the 2011 Desert Research and Technologies Studies (DRaTS) field tests. The HDU project is a "technology-pull" project that integrates technologies and innovations from multiple NASA centers. This project will repurpose the HDU 2010 demo unit that was field tested in the 2010 DRaTS, adding habitation functionality to the prototype unit. This paper will describe the strategy of establishing a multi-center project

    2004-01-01

    In this article we analyze the corporate dominance of health care in the United States and the dynamics that have motivated the international expansion of multinational health care corporations, especially to Latin America. We identify the strategies, actions, and effects of multinational corporations in health care delivery and public health policies. Our methods have included systematic bibliographical research and in-depth interviews in the United States, Mexico, and Brazil. Influenced by public policy makers in the United States, such organizations as the World Bank, International Monetary Fund, and World Trade Organization have advocated policies that encourage reduction and privatization of health care and public health services previously provided in the public sector. Multinational managed care organizations have entered managed care markets in several Latin American countries at the same time as they were withdrawing from managed care activities in Medicaid and Medicare within the United States. Corporate strategies have culminated in a marked expansion of corporations' access to social security and related public sector funds for the support of privatized health services. International financial institutions and multinational corporations have influenced reforms that, while favorable to corporate interests, have worsened access to needed services and have strained the remaining public sector institutions. A theoretical approach to these problems emphasizes the falling rate of profit as an economic motivation of corporate actions, silent reform, and the subordination of polity to economy. Praxis to address these problems involves opposition to policies that enhance corporate interests while reducing public sector services, as well as alternative models that emphasize a strengthened public sector

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

  18. Factors Contributing to Personal Commitment in Chinese Interethnic Couples

    Full Text Available Interethnic relationships are increasingly common in many societies, yet interethnic couples have a higher divorce rate compared to intraethnic couples. Given these facts and the dearth of research, this study aimed to identify factors that contribute to couples’ commitment in interethnic relationships. This study investigated the personal commitment of Chinese interethnic couples in the United Kingdom and the United States. Specifically, whether love, dyadic adjustment and “couple cultural identity” (i.e. acculturation to the partner and couple’s similarity on individualism/collectivism would predict personal commitment and whether each variable would account for unique variance in personal commitment of the participants. Thirty-seven Chinese/non-Chinese heterosexual couples participated in the study and significant relationships between love and personal commitment, dyadic adjustment and personal commitment were found. Also, couple cultural identity was important for women’s personal commitment. Multiple regression and structural equation modelling showed that partners in interethnic relationships defined personal commitment in different ways with men emphasizing love and dyadic adjustment, and women emphasizing love and acculturation to their partner. The discovery of the importance of couple cultural identity in contributing to personal commitment, besides love and dyadic adjustment, helps researchers to gain a greater understanding of such relationships and to extend the research on interethnic relationships.

    The Habitat Demonstration Unit (HDU) project team constructed an analog prototype lunar surface laboratory called the Pressurized Excursion Module (PEM). The prototype unit subsystems were integrated in a short amount of time, utilizing a rapid prototyping approach that brought together over 20 habitation-related technologies from a variety of NASA centers. This paper describes the system integration strategies and lessons learned, that allowed the PEM to be brought from paper design to working field prototype using a multi-center team. The system integration process was based on a rapid prototyping approach. Tailored design review and test and integration processes facilitated that approach. The use of collaboration tools including electronic tools as well as documentation enabled a geographically distributed team take a paper concept to an operational prototype in approximately one year. One of the major tools used in the integration strategy was a coordinated effort to accurately model all the subsystems using computer aided design (CAD), so conflicts were identified before physical components came together. A deliberate effort was made following the deployment of the HDU PEM for field operations to collect lessons learned to facilitate process improvement and inform the design of future flight or analog versions of habitat systems. Significant items within those lessons learned were limitations with the CAD integration approach and the impact of shell design on flexibility of placing systems within the HDU shell.

    The growing number of monitoring devices, combined with suboptimal patient monitoring and alarm management strategies, has increased "alarm fatigue," which have led to serious consequences. Most reported alarm man- agement approaches have focused on the critical care setting. Since 2007 Dartmouth-Hitchcock (Lebanon, New Hamp- shire) has developed a generalizable and effective design, implementation, and performance evaluation approach to alarm systems for continuous monitoring in general care settings (that is, patient surveillance monitoring). In late 2007, a patient surveillance monitoring system was piloted on the basis of a structured design and implementation approach in a 36-bed orthopedics unit. Beginning in early 2009, it was expanded to cover more than 200 inpatient beds in all medicine and surgical units, except for psychiatry and labor and delivery. Improvements in clinical outcomes (reduction of unplanned transfers by 50% and reduction of rescue events by more than 60% in 2008) and approximately two alarms per patient per 12-hour nursing shift in the original pilot unit have been sustained across most D-H general care units in spite of increasing patient acuity and unit occupancy. Sample analysis of pager notifications indicates that more than 85% of all alarm conditions are resolved within 30 seconds and that more than 99% are resolved before escalation is triggered. The D-H surveillance monitoring system employs several important, generalizable features to manage alarms in a general care setting: alarm delays, static thresholds set appropriately for the prevalence of events in this setting, directed alarm annunciation, and policy-driven customization of thresholds to allow clinicians to respond to needs of individual patients. The systematic approach to design, implementation, and performance management has been key to the success of the system.

    Early mobilization of patients in the intensive care unit (ICU) is safe, feasible, and beneficial. However, implementation of early mobility as part of routine clinical care can be challenging. The objective of this review is to identify barriers to early mobilization and discuss strategies to overcome such barriers. Based on a literature search, we synthesize data from 40 studies reporting 28 unique barriers to early mobility, of which 14 (50%) were patient-related, 5 (18%) structural, 5 (18%) ICU cultural, and 4 (14%) process-related barriers. These barriers varied across ICUs and within disciplines, depending on the ICU patient population, setting, attitude, and ICU culture. To overcome the identified barriers, over 70 strategies were reported and are synthesized in this review, including: implementation of safety guidelines; use of mobility protocols; interprofessional training, education, and rounds; and involvement of physician champions. Systematic efforts to change ICU culture to prioritize early mobilization using an interprofessional approach and multiple targeted strategies are important components of successfully implementing early mobility in clinical practice.

    It is stressful for parents to have an infant in the neonatal intensive care unit (NICU). To better understand the parents' experience and the role of staff, we examined parental reports of their NICU experiences, coping strategies, and views of the ways NICU staff supported them. Between June and July 2007, we interviewed 29 current and graduate parents from the study institution's NICU. A trained researcher conducted all interviews, which were recorded and transcribed. This was a qualitative analysis of prospectively collected interview data. Parents used the following coping strategies: (1) participating in care of the child; (2) getting away from the NICU; (3) gathering information; (4) involvement of friends and family; and (5) engagement with other NICU parents. Staff can support the parents' coping strategies in the following ways: (1) facilitating participation of the parents with the infant's care; (2) emphasizing documentation of the infant's progress; (3) demonstrating affection for the infant; (4) addressing concerns that make parents hesitant to leave the NICU; (5) providing accurate, consistent clinical information; (6) limiting unscheduled nonemergency phone calls; and (7) arranging voluntarily activities or programs in which parents whose infants have similar medical conditions may interact.

    We report a sampling strategy based on Mendelian Breeding Units (MBUs), representing an interbreeding group of individuals sharing a common gene pool. The identification of MBUs is crucial for case-control experimental design in association studies. The aim of this work was to evaluate the possible existence of bias in terms of genetic variability and haplogroup frequencies in the MBU sample, due to severe sample selection. In order to reach this goal, the MBU sampling strategy was compared to a standard selection of individuals according to their surname and place of birth. We analysed mitochondrial DNA variation (first hypervariable segment and coding region) in unrelated healthy subjects from two different areas of Sardinia: the area around the town of Cabras and the western Campidano area. No statistically significant differences were observed when the two sampling methods were compared, indicating that the stringent sample selection needed to establish a MBU does not alter original genetic variability and haplogroup distribution. Therefore, the MBU sampling strategy can be considered a useful tool in association studies of complex traits. PMID:21734814

    Full Text Available Introduction. The Centers for Disease Control and Prevention (CDC’s National Tuberculosis Surveillance System (NTSS is the national repository of tuberculosis (TB data in the United States. Jurisdictions report to NTSS through the Report of Verified Case of Tuberculosis (RVCT form that transitioned to a web-based system in 2009. Materials and Methods. To improve RVCT data quality, CDC conducted a quality assurance (QA needs assessment to develop QA strategies. These include QA components (case detection, data accuracy, completeness, timeliness, data security, and confidentiality; sample tools such as National TB Indicators Project (NTIP to identify TB case reporting discrepancies; comprehensive training course; resource guide and toolkit. Results and Discussion. During July–September 2011, 73 staff from 34 (57% of 60 reporting jurisdictions participated in QA training. Participants stated usefulness of sharing jurisdictions’ QA methods; 66 (93% wrote that the QA tools will be effective for their activities. Several jurisdictions reported implementation of QA tools pertinent to their programs. Data showed >8% increase in NTSS and NTIP enrollment through Secure Access Management Services, which monitors system usage, from August 2011–February 2012. Conclusions. Despite challenges imposed by web-based surveillance systems, QA strategies can be developed with innovation and collaboration. These strategies can also be used by other disease programs to ensure high data quality.

In order to achieve the higher system flexibility and reduce the impact of volatility of wind power, ESS is incorporated into the UC problem with wind power. The UC problem with wind power and ESS is formulated as the mixed-integer convex program, which is optimized by branch and bound combined with interior point method. During the branch and bound process, best first search and depth first search are combined to expedite the computation. Numerical simulations on a ten-unit system show that the introduction' of ESS is effective to reduce the impact of volatility of wind power on the UC problem.

    Unconditionally secure quantum bit commitment has been shown to be impossible by Mayers (PRL 78, 3414 (1997)) and Lo and Chau (PRL 78, 3410 (1997)) but the claim is repeatedly challenged. The bit commitment theorem is reviewed here and the central conceptual point, that an 'Einstein-Podolsky-Rosen' attack or cheating strategy can always be applied, is clarified. The question of whether following such a cheating strategy can ever be disadvantageous to the cheater is considered and answered in the negative.

    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.

    Duration of indwelling urinary catheterization is an important risk factor for urinary tract infections. We devised a strategy to decrease the utilization of indwelling urinary catheters (IUCs). We also highlight the challenges of managing critically ill patients without IUCs and demonstrate some of the initiatives that we undertook to overcome these challenges. A retrospective observational outcomes review was performed in an adult medical intensive care unit (ICU) between January 2012 and December 2016. This period included a baseline and series of intervals, whereby different aspects of the strategies were implemented. IUC utilization ratio and catheter-associated urinary tract infection (CAUTI) rates were calculated. Our IUC utilization ratio had a statistically significant decrease from 0.92 (baseline) to 0.28 (after 3 interventions) (P decrease from 5.47 (baseline) to 1.08 (after 3 intervention) (P = .0134). These rates sustained a statistically significant difference over the 2-year follow-up period from the last intervention. Incontinence-associated dermatitis (IAD) was identified as a potential complication of not using an IUC. There was no statistically significant change in the IAD rates during 2013-2016. Our interventions demonstrated that aggressive and comprehensive IUC restriction protocol and provider training can lead to a successful decrease in IUC use, leading to a lower IUC utilization ratio and CAUTI rate in a large complex academic ICU setting.

    This is a summary from a workshop convened as part of the 13(th) annual meeting of the International Scientific Association for Probiotics and Prebiotics. A group of 24 stakeholders, including clinical experts, researchers, federal government officials, funding agencies, lawyers and industry experts met to review the challenges of the current regulatory approach to human research on probiotics in the USA and to discuss ways to move research forward. There was agreement that some of the current regulatory requirements imposed on probiotic research in the United States hindered research progress and increased cost without improving study subject safety. Many situations were outlined by clinical investigators demonstrating the impact of regulatory delays on research progress. Additionally, research is compromised when study designs and outcomes require manipulation so as to invoke less burdensome regulatory requirements. These responses by investigators to regulatory requirements have placed United States' researchers at a disadvantage. The public ultimately suffer when research to clarify the role of these products on health is stalled. Workshop participants concurred that regulatory oversight should balance study subject vulnerability with documented safety for the intended use for the probiotic strain, and that human research on foods and supplements should not be be regulated as drug research. Challenges and potential improvement strategies are discussed.

    In Europe, large volumes of public water supply come from urban aquifers and so efficient urban water management and decision tools are essential to maintain quality of life both in terms of health, personal freedom and environment. In the United Kingdom, this issue gained increased importance with the last year's low volumes of groundwater replenishment that resulted in increased water shortages all over the country. An urban water volume and quality model (UVQ) was applied to a suburb of Doncaster (United Kingdom) to assess the current water supply system and to compare it with new potential scenarios of water management. The initial results show considerable changes in both water and solute fluxes for some scenarios and rather limited changes for others. Changing impermeable roads and paved areas to permeable areas, for example, would lead to higher infiltration rates that may be welcome from a water resources viewpoint but less so from a water quality point of view due to high concentrations of heavy metals. The biggest impact on water quality and quantity leaving the system through sewer, storm water and infiltration system was clearly obtained by re-using grey water from kitchen, bathroom and laundry for irrigation and toilet flush. The testing of this strategy led to lower volumes and higher concentrations of sewerage, a considerable decrease in water consumption and an increase in groundwater recharge. The scenarios were tested neither in terms of costs nor social acceptance for either water supplier or user.

    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.

    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).

    Combining confidence interval based uncertainty analysis on wind power with fuzzy decision-making, a fuzzy unit commitment model of power grid integrated with wind farms, in which the risk of wind power prediction uncertainty is taken into account, is proposed. In the proposed model the fuzzy decision-making is utilized to minimize both generation cost of units and loss-of-load risk of power grid to remedy the defect in existing models that the foundation for the selection of the confidence interval is not given. Besides, in the proposed model an uncertainty model for wind power prediction, which conforms to actual situation, is adopted to ensure the practicality of the proposed model. The proposed model is solved by mixed integer linear programming (MILP). The advantages and validity of the proposed model are verified by simulation results of IEEE RTS 26 test system connected with a wind farm.%结合基于置信区间的风电功率不确定性分析方法和模糊决策方法,提出了计及风电功率预测不确定性风险的含风电场的电力系统模糊机组组合模型。该模型采用模糊决策方法实现了机组发电成本和系统失负荷风险最小的目标,解决了已有模型中未给出置信区间选取依据的不足。此外,该模型采用贴合实际的风电预测不确定模型,保证了该模型的实用性。采用混合整数线性规划(mixed integer linear programming,MILP)方法对所提出的模型进行求解。通过对含风电场的IEEE RTS 26测试系统进行仿真,验证了该模型的有效性和优越性。

    Problems with the recruitment and retention of nurses globally mean that insight into the factors that might increase retention in qualified staff and students is crucial. Despite clear links between work commitment and retention, there is little research exploring commitment in student nurses and midwives. This paper reports the findings of a qualitative study designed to provide insight into commitment using semi-structured interviews conducted with nine pre-registration students and a qualitative survey completed by 171 pre-registration students. Thematic analysis of the data emphasised the impact of placement experiences on commitment via interpersonal relationships. Students typically emphasised their professional identity as the basis for commitment, although many participants also highlighted a lack of acceptance by qualified practitioners, which reduced it. There was evidence that suggested that practitioner workload may impact the student experience due to challenges in making sufficient time to provide support. Implications for retention strategies are discussed.

  5. Commitment to Cooperation and Peer Punishment: Its Evolution

    Full Text Available Theoretical and empirical studies have generally weighed the effect of peer punishment and pool punishment for sanctioning free riders separately. However, these sanctioning mechanisms often pose a puzzling tradeoff between efficiency and stability in detecting and punishing free riders. Here, we combine the key aspects of these qualitatively different mechanisms in terms of evolutionary game theory. Based on the dilemmatic donation game, we introduce a strategy of commitment to both cooperation and peer punishment. To make the commitment credible, we assume that those willing to commit have to make a certain deposit. The deposit will be refunded as long as the committers faithfully cooperate in the donation game and punish free riders and non-committers. It turns out that the deposit-based commitment offers both the efficiency of peer punishment and the stability of pool punishment and that the replicator dynamics lead to transitions of different systems: pool punishment to commitment to peer punishment.

    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.

    Introduction Vertigo can be due to a variety of central and peripheral causes. The relative incidence of central causes is underestimated. This may have an important impact of the patients' management and prognosis. Objective The objective of this work is to determine the incidence of central vestibular disorders in patients presenting to a vestibular unit in a tertiary referral academic center. It also aims at determining the best strategy to increase the diagnostic yield of the patients' visit. Methods This is a prospective observational study on 100 consecutive patients with symptoms suggestive of vestibular dysfunction. All patients completed a structured questionnaire and received bedside and vestibular examination and neuroimaging as required. Results There were 69 women and 31 men. Their ages ranged between 28 and 73 (mean 42.48 years). Provisional videonystagmography (VNG) results were: 40% benign paroxysmal positional vertigo (BPPV), 23% suspicious of central causes, 18% undiagnosed, 15% Meniere disease, and 4% vestibular neuronitis. Patients with an unclear diagnosis or central features (41) had magnetic resonance imaging (MRI) and Doppler studies. Combining data from history, VNG, and imaging studies, 23 patients (23%) were diagnosed as having a central vestibular lesion (10 with generalized ischemia/vertebra basilar insufficiency, 4 with multiple sclerosis, 4 with migraine vestibulopathy, 4 with phobic postural vertigo, and 1 with hyperventilation-induced nystagmus). Conclusions Combining a careful history with clinical examination, VNG, MRI, and Doppler studies decreases the number of undiagnosed cases and increases the detection of possible central lesions.

  12. Verification of a level-3 diesel emissions control strategy for transport refrigeration units

    Science.gov (United States)

    Shewalla, Umesh

    Transport Refrigeration Units (TRUs) are refrigeration systems used to control the environment of temperature sensitive products while they are being transported from one place to another in trucks, trailers or shipping containers. The TRUs typically use an internal combustion engine to power the compressor of the refrigeration unit. In the United States TRUs are most commonly powered by diesel engines which vary from 9 to 40 horsepower. TRUs are capable of both heating and cooling. The TRU engines are relatively small, inexpensive and do not use emissions reduction techniques such as exhaust gas recirculation (EGR). A significant number of these engines operate in highly populated areas like distribution centers, truck stops, and other facilities which make them one of the potential causes for health risks to the people who live and work nearby. Diesel particulate matter (PM) is known for its adverse effects on both human beings and the environment. Considering these effects, regulatory bodies have imposed limitations on the PM emissions from a TRU engine. The objective of this study was to measure and analyze the regulated emissions from a TRU engine under both engine out and particulate filter system out conditions during pre-durability (when the filter system was new) and post-durability test (after the filter system was subjected to 1000 hours in-field trial). The verification program was performed by the Center for Alternative Fuel, Engines and Emissions (CAFEE) at West Virginia University (WVU). In this program, a catalyzed silicon carbide (SiC) diesel particulate filter (DPF) was evaluated and verified as a Level-3 Verified Diesel Emissions Control Strategy (VDECS) (. 85% PM reduction) under California Air Resources Board (CARB) regulations 2702 [1]. The emissions result showed that the filter system reduced diesel PM by a percentage of 96 +/- 1 over ISO 8178-C1 [2] cycle and 92 +/- 5 over EPA TRU [3] cycle, qualifying as a Level 3 VDECS. The percentage

    2012-01-01

    When security-constrained unit commitment (SCUC) was directly solved by mixed integer programming algorithm, the calculation efficiency would considerably decrease, and when SCUC was solved by Benders algorithm, it led to the problem that the solution efficiency would decrease due to the algorithm shock and the restriction of system scale. A new Benders algorithm-based method to solve SCUC was proposed. Based on Benders algorithm, by means of adding the link to correct the constraint of out-of-limit after the iteration of Benders master problem, the search direction of Benders cut could be controlled; by means of adding the link to identify taken-effect constraints the search space of Benders algorithm was reduced, thus the solution efficiency of SCUC optimization could be improved. The effectiveness of the proposed method was verified by simulation results of 6-machine 3-bus system and 54-machine 118-bus system.%针对采用混合整数规划算法直接求解安全约束机组组合,将使计算效率大幅度降低,而利用奔德斯算法求解则存在着算法振荡和受系统规模制约求解效率下降的问题,提出了一种基于奔德斯算法的安全约束机组组合新方法.该方法在奔德斯算法的基础上,通过纳入新增越限约束校正环节,控制了奔德斯割的寻优方向,通过增加起作用约束识别环节,缩小了奔德斯算法的寻优空间,进而提高了安全约束机组组合优化问题的求解效率.6机3节点和54机118节点算例验证了所提方法的有效性.

    In deciding among competing approaches for emissions control, debates often hinge on the potential tradeoffs between efficiency and equity. However, previous health benefits analyses have not formally addressed both dimensions. We modeled the public health benefits and the change in the spatial inequality of health risk for a number of hypothetical control scenarios for power plants in the United States to determine optimal control strategies. We simulated various ways by which emission reductions of sulfur dioxide (SO(2)), nitrogen oxides, and fine particulate matter (particulate matter pollution control strategies, allowing for joint consideration of efficiency and equity.

    People within organizations are a key factor for efficiency. Thus employee empowerment has become a popular management strategy. The study aimed to investigate the relationship between psychological empowerment and organizational commitment among medical staff of a hospital in Zahedan city. This cross sectional study was carried out in 2013. A random sample of 172 medical employees in Khatam-ol-Anbia hospital at Zahedan city was selected and responded to items of the questionnaires using a 7-point Likert scale ranging from 1 to 7. For measuring psychological empowerment and organizational commitment, Mishra & Spreitzer's scale and Meyer and Allen's questionnaire were used. A higher score means a higher degree of psychological empowerment or organizational commitment. Analysis was carried out using SPSS. The level of organizational commitment and psychological empowerment significantly were higher than average. There was a significant positive relationship between employees' empowerment and their commitment to organization. Psychological empowerment was a significant predictor of organizational commitment (β = .524). Out of the five dimensions of empowerment three dimensions are significant predictors of commitment and explain 37.1% of the variance in commitment. Due to The positive influence of psychological empowerment on organizational commitment, programs for in-service education should focus on facilitating psychological empowerment to improve and increase organizational commitment. Also, since impact of employees psychological empowerment on organizational commitment partially supported, there are other variables that influence the organizational commitment.

    Healthcare organizations are now challenged to retain nurses' generation and understand why they are leaving their nursing career prematurely. Acquiring knowledge about the effect of ethical work climate and level of perceived organizational support can help organizational leaders to deal effectively with dysfunctional behaviors and make a difference in enhancing nurses' dedication, commitment, satisfaction, and loyalty to their organization. This study aims to determine the relationship between ethical work climate, and perceived organizational support and nurses' organizational commitment, job satisfaction, and turnover intention. A descriptive correlational research design was conducted in all inpatient care units at three major hospitals affiliated to different health sectors at Alexandria governorate. All nurses working in these previous hospitals were included in the study (N = 500). Ethical Climate Questionnaire, Survey of Perceived Organizational Support, Organizational Commitment Questionnaire, Index of Job Satisfaction, and Intention to Turnover scale were used to measure study variables. Ethical considerations: Approval was obtained from Ethics Committee at Faculty of Nursing, Alexandria University. Privacy and confidentiality of data were maintained and assured by obtaining subjects' informed consent to participate in the research before data collection. The result revealed positive significant correlations between nurses' perception of overall ethical work climate and each of perceived organizational support, commitment, as well as their job satisfaction. However, negative significant correlations were found between nurses' turnover intention and each of these variables. Also, approximately 33% of the explained variance of turnover intention is accounted by ethical work climate, organizational support, organizational commitment, and job satisfaction, and these variables independently contributed significantly in the prediction of turnover intention

  12. Critical Thinking in Critical Care: Five Strategies to Improve Teaching and Learning in the Intensive Care Unit.

    Hayes, Margaret M; Chatterjee, Souvik; Schwartzstein, Richard M

    2017-04-01

    Critical thinking, the capacity to be deliberate about thinking, is increasingly the focus of undergraduate medical education, but is not commonly addressed in graduate medical education. Without critical thinking, physicians, and particularly residents, are prone to cognitive errors, which can lead to diagnostic errors, especially in a high-stakes environment such as the intensive care unit. Although challenging, critical thinking skills can be taught. At this time, there is a paucity of data to support an educational gold standard for teaching critical thinking, but we believe that five strategies, routed in cognitive theory and our personal teaching experiences, provide an effective framework to teach critical thinking in the intensive care unit. The five strategies are: make the thinking process explicit by helping learners understand that the brain uses two cognitive processes: type 1, an intuitive pattern-recognizing process, and type 2, an analytic process; discuss cognitive biases, such as premature closure, and teach residents to minimize biases by expressing uncertainty and keeping differentials broad; model and teach inductive reasoning by utilizing concept and mechanism maps and explicitly teach how this reasoning differs from the more commonly used hypothetico-deductive reasoning; use questions to stimulate critical thinking: "how" or "why" questions can be used to coach trainees and to uncover their thought processes; and assess and provide feedback on learner's critical thinking. We believe these five strategies provide practical approaches for teaching critical thinking in the intensive care unit.

  13. Experimental Research and Control Strategy of Pumped Storage Units Dispatching in the Taiwan Power System Considering Transmission Line Limits

    2013-07-01

    Full Text Available Taiwan’s power system is isolated and not supported by other interconnected systems. Consequently, the system frequency immediately reflects changes in the system loads. Pumped storage units are crucial for controlling power frequency. These units provide main or auxiliary capacities, reducing the allocation of frequency-regulating reserve (FRR and further reducing generation costs in system operations. Taiwan’s Longmen Nuclear Power Plant is set to be converted for commercial operations, which will significantly alter the spinning reserves in the power system. Thus, this study proposes a safe and economic pumped storage unit dispatch strategy. This strategy is used to determine the optimal FRR capacity and 1-min recovery frequency in a generator failure occurrence at the Longmen Power Plant. In addition, this study considered transmission capacity constraints and conducted power flow analysis of the power systems in Northern, Central, and Southern Taiwan. The results indicated that, in the event of a failure at Longmen Power Plant, the proposed strategy can not only recover the system frequency to an acceptable range to prevent underfrequency load-shedding, but can also mitigate transmission line overloading.

  16. Committed warming inferred from observations

    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.

    Research examining the importance of pain beliefs and coping strategies to chronic pain adjustment has been performed almost exclusively using Western populations. The purpose of this study was to examine empirically the generalizability of this research to Singapore. Employing a cross-sectional design, measures assessing pain beliefs, coping strategies, pain intensity, pain interference, and depressive symptoms were administered to 101 patients with chronic pain from Singapore. Analyses examined the means of belief and coping strategies measures and their associations with measures of pain intensity, pain interference, and depressive symptoms and compared the results with the data of a sample of 100 patients with chronic pain from a previously published study from the United States. Mean differences between the Singapore and US samples were found for four of the seven belief scales, and four of the eight coping scales. When significant, associations between belief and coping strategies with measures of pain and dysfunction were in the hypothesized directions in both samples. We also found that the strength of four out of 30 of the associations between beliefs/coping strategies and measures of pain and dysfunction were different between the Singapore and US samples. The findings provide further support for the potential influence of culture on how individuals view and cope with pain. However, the many similarities found in direction and strength of the associations between beliefs/coping strategies and measures of pain/dysfunction provide preliminary support for the appropriateness of the use of cognitive behavioral therapy developed in the United States with the Singapore population.

    2015-03-01

    Part of the work of a critical care nurse is to manage the threats that arise that could impede efficient and effective job performance. Nurses manage threats by employing various strategies to keep performance high and workload manageable. We investigated strategic threat management by using the Threat-Strategy Interview. Threats frequently involved technology, staff, or organizational components. The threats were managed by a toolbox of multifaceted strategies, the most frequent of which involved staff-, treatment- (patient + technology), examination- (patient + clinician), and patient-oriented strategies. The profile of strategies for a particular threat often leveraged work facets similar to the work facet that characterized the threat. In such cases, the nurse's strategy was directed at eliminating the threat (not working around it). A description at both a domain invariant level - useful for understanding strategic threat management generally - and a description at an operational, specific level - useful for guiding interventions-- are presented. A structural description of the relationship among threats, strategies, and the cues that trigger them is presented in the form of an evidence accumulation framework of strategic threat management.

    Although many studies link teamwork in health care settings to patient safety, evidence linking teamwork to hospital worker safety is lacking. This study addresses this gap by providing evidence linking teamwork perceptions in hospital workers to worker injuries, and further, finds a linkage between manager commitment to safety and teamwork. Organizational records of worker injuries and survey responses regarding management commitment to safety and teamwork from 446 hospital workers within 42 work units in a multi-site hospital system were examined. Results underscored the particular importance of teamwork on worker injuries as well as the importance of management commitment to safety as relating to teamwork. To improve worker safety, organizational leaders and unit managers should work to maintain environments wherein teamwork can thrive.

All subjects were right-handed and right-footed for mobilization tasks. Participants were instructed to turn 180° in a self-selected direction after a 10-m walk while wearing three IMUs on their trunk and both feet. We defined three turning patterns based on the number of external steps (pattern I = 1; II = 2–4 steps; and III ≥ 5 and four turning strategies based on the side chosen to turn (healthy or paretic and the stance limb used during the first step of the turn (healthy or paretic. Falls in the 6 months after measurement were investigated.ResultsWe included 17 RP [mean (SD age 57.5 (9.5 years (range 43–73], 20 LP patients [mean age 60.7 (8.8 years (range 43–63], and 15 HCs [mean age 56.7 (16.1 years (range 36–83]. The LP and RP groups behaved similarly in turning patterns, but 90% of LP patients turned spontaneously to the paretic side versus 59% of RP patients. This difference increased with turning strategies: 85% of LP versus 29% of RP patients used strategy 4 (paretic turn side with paretic limb. Patients using strategy 4 had the highest rate of falls.ConclusionWe propose to consider spontaneous turning strategies as new indicators to evaluate the risk of fall after stroke. IMU could be routinely used to identify this risk and guide balance rehabilitation programs.

    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.

  6. 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.

    Stem cells (SCs) are undifferentiated cells responsible for the growth, homeostasis and repair of many tissues. The maintenance and survival of SCs is strongly influenced by several stimuli from the local microenvironment. The majority of signaling molecules interact with SCs at the nanoscale level. Therefore, scaffolds with surface nanostructures have potential applications for SCs and in the field of regenerative medicine. Although some strategies have already reached the field of cell biology, strategies based on modification at nanoscale level are new players in the fields of SCs and tissue regeneration. The introduction of the possibility to perform such modifications to these fields is probably due to increasing improvements in nanomaterials for biomedical applications, as well as new insights into SC biology. The aim of the present review is to exhibit the most recent applications of nanostructured materials that drive the commitment of adult SCs for potential clinical applications.

A data-driven grey-box identification approach provided the physically–meaningful nonlinear continuous-time model, which represents the benchmark exploited in this work. The control problem of this thermal unit is important, since it constitutes the key element of passive air conditioning systems. The advanced control schemes analysed in this paper are used to regulate the outflow air temperature of the thermal unit by exploiting the inflow air speed, whilst the inflow air temperature is considered as an external disturbance. The reliability and robustness issues of the suggested control methodologies are verified with a Monte Carlo (MC analysis for simulating modelling uncertainty, disturbance and measurement errors. The achieved results serve to demonstrate the effectiveness and the viable application of the suggested control solutions to air conditioning systems. The benchmark model represents one of the key issues of this study, which is exploited for benchmarking different model-based and data-driven advanced control methodologies through extensive simulations. Moreover, this work highlights the main features of the proposed control schemes, while providing practitioners and heating, ventilating and air conditioning engineers with tools to design robust control strategies for air conditioning systems.

  11. Conscientious commitment to women's health.

    Dickens, Bernard M; Cook, Rebecca J

    2011-05-01

    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.

  12. Strategies used by adults to reduce their prescription drug costs: United States, 2013.

    Science.gov (United States)

    Cohen, Robin A; Villarroel, Maria A

    2015-01-01

    Among U.S. adults aged 18-64, strategies for reducing prescription drug costs were more commonly practiced by those who were uninsured than those who had public or private coverage. Lack of health insurance coverage and poverty are recognized risk factors for not taking medication as prescribed due to cost. This cost-saving strategy may result in poorer health status and increased emergency room use and hospitalizations, compared with adults who follow their recommended pharmacotherapy. It is unknown whether adverse health outcomes and higher health care costs are also associated with the cost-reduction strategies of alternative therapy use or obtaining prescription drugs from abroad. Among adults aged 65 and over, those covered by both Medicare and Medicaid were more likely to have not taken their medication as prescribed to save money, but were less likely to have asked their doctor for a lower-cost prescription, than those who had private insurance coverage. Differences in cost-saving strategies by insurance coverage may be interrelated with socioeconomic and other patient characteristics. Belief that the recommended pharmacotherapy is needed, and an understanding of the recommended treatment, have been found to be lower among older adults who are economically vulnerable, compared with those with higher income. Income was also associated with the use of cost-reduction strategies. Among adults aged 65 and over, those living with incomes at 139%-400% FPL were more likely than adults living in lower or higher income thresholds to have asked their provider for a lower-cost prescription to save money. These patterns in the estimates by insurance status and poverty level are similar to those previously reported using the 2011 NHIS data.

    Hispanics are the fastest growing racial/ethnic group in the United States, and smoking is the leading preventable cause of morbidity and mortality among this population. We analyzed tobacco industry documents on R. J. Reynolds’ marketing strategies toward the Hispanic population using tobacco industry document archives from the Legacy Tobacco Documents Library (http://legacy.library.ucsf.edu) between February–July 2011 and April–August 2012. Our analysis revealed that by 1980 the company had developed a sophisticated surveillance system to track the market behavior of Hispanic smokers and understand their psychographics, cultural values, and attitudes. This information was translated into targeted marketing campaigns for the Winston and Camel brands. Marketing targeted toward Hispanics appealed to values and sponsored activities that could be perceived as legitimating. Greater understanding of tobacco industry marketing strategies has substantial relevance for addressing tobacco-related health disparities. PMID:23488493

  1. The Mature Imagination and Consumption Strategies: Age & Generation in the Development of a United Kingdom Baby Boomer Identity

    Directory of Open Access Journals (Sweden)

    2008-04-01

    Full Text Available Baby boomers have been credited with an essentially ‘youthful’ approach to themselves, to consumption and to life-style. As they enter midlife and older age they are also faced with the challenges of a mature identity. This paper critically examines the strategies that baby boomers in the United Kingdom use to manage identity as they grow older. Specifically, questions concerning attitudes to cohort labels, personal ageing and other generations are compared to the consumption choices that are made in areas considered to be key to an ageing identity, including: appearance, clothing and bodily maintenance. Boomers identify with succeeding rather than preceding generations. While they claim not to be concerned with bodily ageing as such, their strategies are aimed at maintaining a balance between youthful and mature identities. Priority was given to blurring the boundaries between themselves and younger adult generations. The implications for the relationship between adult ageing and patterns of consumption are explored.

    Full Text Available Renal failure is a common complication among critically ill patients. Timing, dosage, and mode of renal replacement (RRT are under debate, but also anticoagulation strategies and vascular access interfere with dialysis success. We present a retrospective, five-year evaluation of patients requiring RRT on a multidisciplinary 50-bed surgical intensive care unit of a university hospital with special regard to anticoagulation strategies and vascular access. Anticoagulation was preferably performed with unfractionated heparin or regional citrate application (RAC. Bleeding and suspected HIT-II were most common causes for RAC. In CVVHD mode filter life span was significantly longer under RAC compared to heparin or other anticoagulation strategies (P=0.001. Femoral vascular access was associated with reduced filter life span (P=0.012, especially under heparin anticoagulation (P=0.015. Patients on RAC had higher rates of metabolic alkalosis (P=0.001, required more transfusions (P=0.045, and showed higher illness severity measured by SOFA scores (P=0.001. RRT with unfractionated heparin represented the most common anticoagulation strategy in this study population. However, patients with bleeding risk and severe organ dysfunction were more likely placed on RAC. Citrate provided longer filter life spans regardless of vascular access site. Attention has to be paid to metabolic disturbances.

    Abstract:
    Background: between May 2010 and october 2011 the unit of Preventive Medicine for the developmental ages of district IV, Health unit aSL rM/a, received 136 measles case notifications from the unit of Epidemiology and Prophylaxis of Infectious diseases.
    Methods: in accordance with the infectious diseases monitoring protocol, we introduced a series of preventive measures, such as monitoring subjects in contact with measles-infected patients, recommend- ing the administration of two Measles Mumps and rubella (MMr doses four weeks apart, and informing paediatricians, families and school teachers about the measles epidemic.
    Results: all the activities above led to an increased number of MMr doses administered and a significant improvement of measles immunization coverage among residents of the district IV health unit of rome. concerning MMr 1, in a sample cohort consisting of children ≤24 months, the immunization coverage increased from 77% on the 31/12/09 to 88% on the 31/12/11. Instead, for MMr 2, in a cohort of children ≤6 years, the same ratio improved from 51% on the 31/12/09 to 65% on the 31/12/11.
    Discussion: the results indicate a material increase in the immunization coverage once our public health actions and vaccination strategies had been implemented among young residents of district IV aSL rM/a...

    In the field of tissue engineering, adult stem cells are increasingly recognized as an important tool for in vitro reconstructed tissue-engineered grafts. In the world of cell therapies, undoubtedly, mesenchymal stem cells from bone marrow or adipose tissue are the most promising progenitors for tissue engineering applications. In this setting, adipose-derived stem cells (ASCs) are generally similar to those derived from bone marrow and are most conveniently extracted from tissue removed by elective cosmetic liposuction procedures; they also show a great potential for endothelization. The aim of the present work was to investigate how the cocommitment into a vascular and bone phenotype of ASCs could be a useful tool for improving the in vitro and in vivo reconstruction of a vascularized bone graft. Human ASCs obtained from abdominoplasty procedures were loaded in a hydroxyapatite clinical-grade scaffold, codifferentiated, and tested for proliferation, cell distribution, and osteogenic and vasculogenic gene expression. The chromosomal stability of the cultures was investigated using the comparative genomic hybridization array for 3D cultures. ASC adhesion, distribution, proliferation, and gene expression not only demonstrated a full osteogenic and vasculogenic commitment in vitro and in vivo, but also showed that endothelization strongly improves their osteogenic commitment. In the end, genetic analyses confirmed that no genomical alteration in long-term in vitro culture of ASCs in 3D scaffolds occurs.

    Al-Ain is the second largest city in the Emirate of Abu Dhabi and the third in the UAE. Currently, desalination plants are the only source of drinking water in the city with an average daily supply of 170 MIG. Recently, Abu Dhabi Urban Planning Council (UPC) released Al-Ain 2030 Plan. Projects suggested in this plan, over and above the expected natural population growth, will certainly put additional stress on the water resources in the city. Therefore, Al-Ain city seems to be in urgent need for an integrated water resources management strategy towards achieving sustainable development. This strategy will contain three main components; namely, a Water Demand Forecasting Model (WDFM), a Water Budget Model (WBM), and a Water Resources Optimization Model (WROM). The main aim of this paper is to present the WBM that estimates all inflows and outflows to assess water resources sustainability in the city.

    Full Text Available Objective: To identify and analyze the production of knowledge about the strategies that health care institutions have implemented to humanize care of hospitalized children. Method: This is a systematic review conducted in the Virtual Health Library - Nursing and SciELO, using the seven steps proposed by the Cochrane Handbook. Results: 15 studies were selected, and strategies that involved relationship exchanges were used between the health professional, the hospitalized child and their families, which may be mediated by leisure activities, music and by reading fairy tales. We also include the use of the architecture itself as a way of providing welfare to the child and his/her family, as well as facilitating the development of the work process of health professionals. Conclusion: Investments in research and publications about the topic are necessary, so that, the National Humanization Policy does not disappear and that the identified strategies in this study do not configure as isolated and disjointed actions of health policy.

  10. Reinforcement of smoking and drinking: tobacco marketing strategies linked with alcohol in the United States.

    Jiang, Nan; Ling, Pamela M

    2011-10-01

    We investigated tobacco companies' knowledge about concurrent use of tobacco and alcohol, their marketing strategies linking cigarettes with alcohol, and the benefits tobacco companies sought from these marketing activities. We performed systematic searches on previously secret tobacco industry documents, and we summarized the themes and contexts of relevant search results. Tobacco company research confirmed the association between tobacco use and alcohol use. Tobacco companies explored promotional strategies linking cigarettes and alcohol, such as jointly sponsoring special events with alcohol companies to lower the cost of sponsorships, increase consumer appeal, reinforce brand identity, and generate increased cigarette sales. They also pursued promotions that tied cigarette sales to alcohol purchases, and cigarette promotional events frequently featured alcohol discounts or encouraged alcohol use. Tobacco companies' numerous marketing strategies linking cigarettes with alcohol may have reinforced the use of both substances. Because using tobacco and alcohol together makes it harder to quit smoking, policies prohibiting tobacco sales and promotion in establishments where alcohol is served and sold might mitigate this effect. Smoking cessation programs should address the effect that alcohol consumption has on tobacco use.

    The current challenges facing healthcare systems, in relation to the shortage of health professionals, necessitates mangers and leaders to learn from different leadership styles and staff empowerment strategies, so as to create a work environment that encourages nursing staff commitment to patients and their organization. This study intends to measure the effects of nurses' overall perception of the leadership style of their managers, and psychological empowerment on their organizational commitment in acute care units, in National Guard Health Affairs, Riyadh City, Saudi Arabia. This was a cross-sectional survey, where the data was obtained from nurses at King Abdulaziz Medical City. Hard copy questionnaires were distributed to 350 randomly selected nurses. Three hundred and thirty two (332) were completed, representing a response rate of 95 %. Three validated survey instruments were used to obtain the data: (1) The Multifactor Leadership Questionnaire (MLQ), formulated by Bass and Avolio (1997), (2) The Psychological Empowerment Scale developed by Spreitzer (1995) and (3) The Three-Component Model of Employee Commitment developed by Meyer and Allen (1997). A theoretical model that conceptually links leadership, empowerment, and organizational commitment was used. The SPSS program version 19 was employed to perform descriptive and inferential statistics including correlation and stepwise multiple regression analysis. Overall most nurses perceived their immediate nursing managers as not displaying the ideal level of transformational leadership (TFL) behaviors. Nurses' commitment appeared to be negatively correlated with TFL style and perceived psychological empowerment. However, commitment was positively correlated with the Transactional Leadership (TAL) style. Analysis, also, showed that commitment is significantly associated with the nurse's nationality by region: North American (P = 0.001) and Arab (p = 0.027). The other important predictors of

    We study the effects of environmental policy commitments in a futuristic world in which solar radiation management (SRM) can be utilized to reduce climate change damages. Carbon and sulfur dioxide emissions (correlated pollutants) can be reduced through tradable permits. We show that if nations simultaneously commit to carbon permit policies, national SRM levels rise with carbon quotas. Alternatively, if they simultaneously commit to SRM policies, the global temperature falls with each unit increase in the global SRM level. A nation always wishes to be a leader in policymaking, but prefers carbon to SRM policymaking. The globe prefers SRM policy commitments. Copyright © 2014 Elsevier Ltd. All rights reserved.

    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.

    We modeled the public health benefits and the change in the spatial inequality of health risk for a number of hypothetical control scenarios for power plants in the United States to determine optimal control strategies. We simulated various ways by which emission reductions of sulfur dioxide (SO{sub 2}), nitrogen oxides, and fine particulate matter (PM2.5) could be distributed to reach national emissions caps. We applied a source-receptor matrix to determine the PM2.5 concentration changes associated with each control scenario and estimated the mortality reductions. We estimated changes in the spatial inequality of health risk using the Atkinson index and other indicators, following previously derived axioms for measuring health risk inequality. In our baseline model, benefits ranged from 17,000-21,000 fewer premature deaths per year across control scenarios. Scenarios with greater health benefits also tended to have greater reductions in the spatial inequality of health risk, as many sources with high health benefits per unit emissions of SO{sub 2} were in areas with high background PM2.5 concentrations. Sensitivity analyses indicated that conclusions were generally robust to the choice of indicator and other model specifications. Our analysis demonstrates an approach for formally quantifying both the magnitude and spatial distribution of health benefits of pollution control strategies, allowing for joint consideration of efficiency and equity.

  13. Why Quantum Bit Commitment And Ideal Quantum Coin Tossing Are Impossible

    CERN Document Server

    Lo, H K

    1998-01-01

    There had been well known claims of unconditionally secure quantum protocols for bit commitment. However, we, and independently Mayers, showed that all proposed quantum bit commitment schemes are, in principle, insecure because the sender, Alice, can almost always cheat successfully by using an Einstein-Podolsky-Rosen (EPR) type of attack and delaying her measurements. One might wonder if secure quantum bit commitment protocols exist at all. We answer this question by showing that the same type of attack by Alice will, in principle, break any bit commitment scheme. The cheating strategy generally requires a quantum computer. We emphasize the generality of this ``no-go theorem'': Unconditionally secure bit commitment schemes based on quantum mechanics---fully quantum, classical or quantum but with measurements---are all ruled out by this result. Since bit commitment is a useful primitive for building up more sophisticated protocols such as zero-knowledge proofs, our results cast very serious doubt on the secur...

    National Pain Strategy population research objectives include: estimating chronic pain prevalence, studying pain treatment with electronic health care data, and developing metrics to assess progress in reducing chronic pain impact. In this article, the National Pain Strategy Population Research Workgroup reviews concepts relevant to achieving these aims. High-impact chronic pain was defined as persistent pain with substantial restriction of life activities lasting 6 months or more. In pilot work, we tested a brief assessment of high-impact chronic pain, and used electronic health records data to describe pain-related health care. A mail survey of adult health plan enrollees (N = 770) reported that 14% had high-impact chronic pain. Relative to persons with lower-impact chronic pain, those with high-impact chronic pain were more often frequent users of health care for pain, reported lower quality of life, greater pain-related interference with activities, and more often reported pain at multiple anatomic locations. Analyses of health care data (N = 289,464) reported that pain patients had higher health care costs compared with others and that pain services were typically delivered in primary care. These results support the feasibility of developing data on chronic pain through national health interview surveys and large electronic health care databases. Pilot analyses supported the feasibility of brief chronic pain assessments suitable for national health surveys and use of electronic health care databases to develop data regarding trends in the delivery of pain treatments, costs, and effectiveness. These methods are relevant to achieving the aims of the US National Pain Strategy. Copyright © 2016 American Pain Society. All rights reserved.

    2009-08-27

    Estimating the potential health benefits and expenditures of a partially effective HIV vaccine is an important consideration in the debate about whether HIV vaccine research should continue. We developed an epidemic model to estimate HIV prevalence, new infections, and the cost-effectiveness of vaccination strategies in the U.S. Vaccines with modest efficacy could prevent 300,000-700,000 HIV infections and save $30 billion in healthcare expenditures over 20 years. Targeted vaccination of high-risk individuals is economically efficient, but difficulty in reaching these groups may mitigate these benefits. Universal vaccination is cost-effective for vaccines with 50% efficacy and price similar to other infectious disease vaccines.

    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.

    2013-11-01

    Full Text Available This qualitative study investigated the existing outlooks of internationalization in higher education in US universities having a sizable international student population attending their campuses. The purpose of this research was to explore the common practices for internationalization of higher education in US institutions. This study utilized Zha’s (2003 conceptual and organizational framework of internationalization of higher education: the activity approach, which includes curricula, studying abroad, internationalizing faculty, and recruitment of international students. Other components of the framework include: the competency approach, which includes development of knowledge and skills, the ethos approach which focuses on the infusion of intercultural and international initiatives, and the process approach which seeks internationalization by means of inclusion of international and intercultural dimensions into teaching, service, and research. A correlation was discovered between the cited literature and raw data that was analyzed. The main themes indicating current practices that higher education institutions were employing to increase internationalization were: 1 hosting international events for training and education on culture and diversity, and 2 having international dimensions within their institutional infrastructure. This study suggests that internationalization of higher education in the United States needs to continue, evolve, and expand, especially since globalization trends make it more pertinent to the understanding of various cultures. In order for higher education in the United States to be competitive and viable in the global market, there needs to be a sustained goal in internationalizing teaching, learning, and practices.

    Full Text Available Abstract For the past decade, the Food and Agriculture Organization of the United Nations has been working toward eradicating rinderpest through vaccination and intense surveillance by 2012. Because of the potential severity of a rinderpest epidemic, it is prudent to prepare for an unexpected outbreak in animal populations. There is no immunity to the disease among the livestock or wildlife in the United States (US. If rinderpest were to emerge in the US, the loss in livestock could be devastating. We predict the potential spread of rinderpest using a two-stage model for the spread of a multi-host infectious disease among agricultural animals in the US. The model incorporates large-scale interactions among US counties and the small-scale dynamics of disease spread within a county. The model epidemic was seeded in 16 locations and there was a strong dependence of the overall epidemic size on the starting location. The epidemics were classified according to overall size into small epidemics of 100 to 300 animals (failed epidemics, epidemics infecting 3 000 to 30 000 animals (medium epidemics, and the large epidemics infecting around one million beef cattle. The size of the rinderpest epidemics were directly related to the origin of the disease and whether or not the disease moved into certain key counties in high-livestock-density areas of the US. The epidemic size also depended upon response time and effectiveness of movement controls.

  3. Farmer perceptions of climate change risk and associated on-farm management strategies in Vermont, northeastern United States

    2016-10-01

    Full Text Available Abstract Little research has been conducted on how agricultural producers in the northeastern United States conceptualize climate-related risk and how these farmers address risk through on-farm management strategies. Two years following Tropical Storm Irene, our team interviewed 15 farmers in order to investigate their perceptions of climate-related risk and how their decision-making was influenced by these perceptions. Our results show that Vermont farmers are concerned with both ecological and economic risk. Subthemes that emerged included geographic, topographic, and hydrological characteristics of farm sites; stability of land tenure; hydrological erosion; pest and disease pressure; market access; household financial stability; and floods. Farmers in our study believed that these risks are not new but that they are significantly intensified by climate change. Farmer responses were heavily focused on adaptation activities, with discussion of climate change mitigation activities notably absent. Psychological distance construal theory and hyperbolic discounting emerged as well-suited frames to explain why farmers reported adaptation activities but not mitigation strategies. Farmers will probably experience an increasing severity of climate-related impacts in the northeast region; therefore, information about climate-related risks coming from farmers’ personal experience should be integrated with forecasting data to help farmers plan effective adaptation strategies.

  4. Ownership, financing, and management strategies of the ten largest for-profit nursing home chains in the United States.

    2011-01-01

    This study examined the ownership, financing, and management strategies of the 10 largest for-profit nursing home chains in the United States, including the four largest chains purchased by private equity corporations. Descriptive data were collected from Internet searches, company reports, and other sources for the decade 1998-2008. Since 1998, the largest chains have made many changes in their ownership and structure, and some have converted from publicly traded companies to private ownership. This study shows the increasing complexity of corporate nursing home ownership and the lack of public information about ownership and financial status. The chains have used strategies to maximize shareholder and investor value that include increasing Medicare revenues, occupancy rates, and company diversification, establishing multiple layers of corporate ownership, developing real estate investment trusts, and creating limited liability companies. These strategies enhance shareholder and investor profits, reduce corporate taxes, and reduce liability risk. There is a need for greater transparency in ownership and financial reporting and for more government oversight of the largest for-profit chains, including those owned by private equity companies.

  5. Dual recognition unit strategy improves the specificity of the adenosine triphosphate (ATP) aptamer biosensor for cerebral ATP assay.

    Adenosine triphosphate (ATP) aptamer has been widely used as a recognition unit for biosensor development; however, its relatively poor specificity toward ATP against adenosine-5'-diphosphate (ADP) and adenosine-5'-monophosphate (AMP) essentially limits the application of the biosensors in real systems, especially in the complex cerebral system. In this study, for the first time, we demonstrate a dual recognition unit strategy (DRUS) to construct a highly selective and sensitive ATP biosensor by combining the recognition ability of aptamer toward A nucleobase and of polyimidazolium toward phosphate. The biosensors are constructed by first confining the polyimidazolium onto a gold surface by surface-initiated atom transfer radical polymerization (SI-ATRP), and then the aptamer onto electrode surface by electrostatic self-assembly to form dual-recognition-unit-functionalized electrodes. The constructed biosensor based on DRUS not only shows an ultrahigh sensitivity toward ATP with a detection limit down to the subattomole level but also an ultrahigh selectivity toward ATP without interference from ADP and AMP. The constructed biosensor is used for selective and sensitive sensing of the extracellular ATP in the cerebral system by combining in vivo microdialysis and can be used as a promising neurotechnology to probing cerebral ATP concentration.

    Full Text Available This study aimed to analyze the relation between the individual’s patterns of ties with the organization, emotional expressions, and the use of emotional regulation strategies to deal with work situations. The instrument used for data collection included a scale to measure commitment and entrenchment and 21 work settings for which participants had to assign emotion regulation strategies. Participants included 400 employees of public institutions located in Florianopolis. The article is structured into sections that discuss the core concepts, describe the method, present and debate the results. In the sample result most individuals showed high levels of commitment and use of deep emotional control strategies. Anger was the most frequent emotion and, conversely, fear was the less common.

    2016-12-01

    Efforts to regulate emotions can influence others, and interpersonal emotion regulation within teams may affect athletes' own affective and motivational outcomes. We examined adolescent athletes' (N = 451, N teams = 38) self- and interpersonal emotion regulation, as well as associations with peer climate, sport enjoyment, and sport commitment within a multilevel model of emotion regulation in teams. Results of multilevel Bayesian structural equation modeling showed that athletes' self-worsening emotion regulation strategies were negatively associated with enjoyment while other-improving emotion regulation strategies were positively associated enjoyment and commitment. The team-level interpersonal emotion regulation climate and peer motivational climates were also associated with enjoyment and commitment. Team-level factors moderated some of the relationships between athletes' emotion regulation with enjoyment and commitment. These findings extend previous research by examining interpersonal emotion regulation within teams using a multilevel approach, and they demonstrate the importance of person- and team-level factors for athletes' enjoyment and commitment.

    Anemia is a common problem in the ICU population. Most patients are anemic at admission, their hemoglobin concentrations declining further thereafter. The aim of the present study was to evaluate the effect of a combination strategy, involving closed arterial blood gas sampling and the use of pediatric vials for phlebotomy (Group A), on the sampling-induced blood loss and the rate of decline in hemoglobin in adult ICU patients. Combination (Group A) was compared to the current standard technique of arterial line sampling and adult vial phlebotomy (Group B) in a prospective, randomised, ethically-approved trial for the first 72 hours of their ICU stay. Peri-operative, oncology, coagulopathic and uremic patients were excluded. All other ICU patients with arterial cannulae and predicted to stay beyond 3 days, were enrolled.

    1983-01-01

    This study recounts the development of US nuclear strategy during its formative period, and argues that it was shaped less by high policy guidance than by dynamics of targeting and operational planning. From 1948 on, responsibility for nuclear war planning at an operational level rested primarily with the Strategic Air Command. SAC plans were based on broad target priorities and damage criteria established by the Joint Chiefs of Staff, but reflected the limitations imposed by inadequate intelligence, the desire to achieve maximum effect with a limited atomic stockpile, and concerns about operational capability and efficiency. They called for a massive, simultaneous, non-discriminating attack on all known Soviet military and urban-industrial targets at the outbreak of general war. Although Presidents Truman and Eisenhower both decisively rejected the concept of preventive war, neither was willing to rule out the option of preempting an impending Soviet nuclear strike by the rapid implementation of such an offensive.

    Knowledge capital is becoming more important to healthcare establishments, especially for hospitals that are facing changing societal and industrial patterns. Hospital staff must engage in a process of continual learning to improve their healthcare skills and provide a superior service to their patients. Internal marketing helps hospital administrators to improve the quality of service provided by nursing staff to their patients and allows hospitals to build a learning culture and enhance the organizational commitment of its nursing staff. Our empirical study provides nursing managers with a tool to allow them to initiate a change in the attitudes of nurses towards work, by constructing a new 'learning organization' and using effective internal marketing. A cross-sectional design was employed. Two hundred questionnaires were distributed to nurses working in either a medical centre or a regional hospital in Taichung City, Taiwan, and 114 valid questionnaires were returned (response rate: 57%). The entire process of distribution and returns was completed between 1 October and 31 October 2009. Hypothesis testing was conducted using structural equation modelling. A significant positive correlation was found between the existence of a 'learning organization', internal marketing, and organizational commitment. Internal marketing was a mediator between creating a learning organization and organizational commitment. Nursing managers may be able to apply the creation of a learning organization to strategies that can strengthen employee organizational commitment. Further, when promoting the creation of a learning organization, managers can coordinate their internal marketing practices to enhance the organizational commitment of nurses.

Peri-operative, oncology, coagulopathic and uremic patients were excluded. All other ICU patients with arterial cannulae and predicted to stay beyond 3 days, were enrolled. RESULTS: 39 patients entered the study, 20 in Group A, and 19 in Group B. Data collection was complete for all. There was a statistically significant difference in sampling-induced blood loss between the groups over the first 72 hours of treatment (mean +\\/- standard deviation: 15.16 +\\/- 5.3 ml Group A vs 45.11 +\\/- 14 ml Group B, p<0.001). There was a smaller decline in mean hemoglobin level, which was not statistically significant (0.79 +\\/- 0.6 g\\/dL vs 1.30 +\\/- 1.13, p = 0.09). CONCLUSIONS: Overall, this strategy reduced measurable blood losses from phlebotomy. In larger trials it might also preserve hemoglobin levels.

    2016-03-01

    Full Text Available Orientation:  The United Arab Emirates’ labour market by design is inclined to exclude generally the Emirati population from active participation in the private sector, in order to take advantage of cheap labour primarily from South Asia.Research purpose: The aim of this article was to explain, using labour market segmentation theory, how the present epoch of free market capitalism in the ‘minority state’ of the United Arab Emirates (UAE has socially excluded its’ citizens.Motivation for the study:  The pro-national Emiratisation or employment policy project implemented by the federal government in 1998 provided an opportunity for UAE citizens to be fully absorbed in the private and public sectors. Researching the process as it unfolded, insights are unearthed as to why Emirati citizens are still on the periphery of the country’s labour market.Research design, approach and method:  The article employed a qualitative methodology using the UAE as a single case study.Main findings: The research on the UAE’s Emiratisation or labour nationalisation policies found that there are a number of systemic and structural barriers that have hampered the successful implementation of government policies in both the private and public sectors.Practical/managerial implications: Policy makers need to be able to differentiate between the systemic, structural and institutional factors that have stymied government’s attempt at addressing the country’s demographic imbalance and the social exclusion of Emirati citizens from the labour market.Contribution/value-add: This research has filled a gap in literature on the theme, and has also deviated from earlier research findings on the barriers to achieving policy targets.

  13. How do different types of community commitment influence brand commitment? The mediation of brand attachment.

    2013-11-01

    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.

    2014-12-01

    Full Text Available Food security is now commonly seen as one of the defining global issues of the century, intertwined with population and consumption shifts, climate change, environmental degradation, water scarcity, and the geopolitics attending globalization. Some analysts suggest that food security threats are so urgent that philosophical scruples must be set aside in order to concentrate all resources on developing and implementing radical strategies to avert a looming civilizational crisis. This article suggests that definitions of food security invoke commitments and have consequences, and that continued critical and conceptual attention to the language employed in food security research and policy is warranted.

    In classical cryptography, the bit commitment scheme is one of the most important primitives. We review the state of the art of bit commitment protocols, emphasizing its main achievements and applications. Next, we present a practical quantum bit commitment scheme, whose security relies on current technological limitations, such as the lack of long-term stable quantum memories. We demonstrate the feasibility of our practical quantum bit commitment protocol and that it can be securely implemented with nowadays technology.

As Avedis Donabedian detailed a half century ago, defining metrics in healthcare can be challenging; algorithmic determination of the best type of metric (outcome, process, or structure) can help intensive care unit (ICU) managers begin this process. Choosing appropriate graphical data displays (e.g., run charts) can prompt discussions about and promote quality improvement. Similarly, dashboards/scorecards are useful in presenting performance improvement data either publicly or privately in a visually appealing manner. To have compelling data to show, ICU managers must plan quality-improvement projects well. The second portion of this review details four quality-improvement tools-checklists, Six Sigma methodology, lean thinking, and Kaizen. Checklists have become commonplace in many ICUs to improve care quality; thinking about how to maximize their effectiveness is now of prime importance. Six Sigma methodology, lean thinking, and Kaizen are techniques that use multidisciplinary teams to organize thinking about process improvement, formalize change strategies, actualize initiatives, and measure progress. None originated within healthcare, but each has been used in the hospital environment with success. To conclude this part of the series, we demonstrate how to use these tools through an example of improving the timely administration of antibiotics to patients with sepsis.

    This essay explores numerous and complicated naturalized epistemology against the background of pragmatism.We distinguish three programmes of naturalized epistemology:strong,moderate,and weak.By considering commitments of pragmatism on which different programmes depend,we point out the close-knit relationship between pragmatism and naturalized epistemology.We also illustrate the essential origin of today's controversy over naturalized epistemology and predict the uptrend of naturalized epistemology.

  19. 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...

  1. 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 Establishing bare-root transplants in Florida, United States, is an inefficient water-consuming activity. Between 3500 and 5500 m3/ha are applied with sprinkler irrigation to lower temperatures around the transplant crown and aid early root development, but more than 97% of the water volume runs off the polyethylene-covered beds. Research has been conducted to evaluate the feasibility of producing containerized (plug short-day cultivar transplants under Florida conditions, the effect of continuous and intermittent low-volume sprinklers on transplant establishment and the use of kaolin clay to reduce stress on young transplants. Research results demonstrated that growers may have alternatives to reduce water use and pumping costs during strawberry transplant establishment by the following: (a plug transplants can be produced from mother plants from Florida’s subtropical weather without chilling conditioning and still be competitive in the winter market; (b using continuous and intermittent low-volume sprinkler irrigation saves between 16% and 33% of the water volumes for strawberry establishment; and (c using kaolin clay showed to be a low-cost (US$63/ha plus application costs investment to reduce irrigation volumes by at least 30%.

    Full Text Available The purpose of the study was to examine the impact and the extent to which global Cultural differences affects a company’s pricing decisions, a study based on Da-Wood Trading in the United States of America. Data for this study was collected through observation during a three month internship at the company, and questionnaires were later administered to respondents. Personal interview was also used to gather data from one respondent. The findings were then presented in form of tables and graphs. The data collected indicates that there are globalization factors that play a role in determining prices for services offered. Exposure to crime comes out as the most prominent global political factor while literacy rates and global oil prices stand out as the most influential cultural and economic factors, respectively. However, factors like tariffs, religion, and currency fluctuations are seen to not have a significant impact on pricing decisions. The factors that are considered and highlighted in this study therefore are seen to vary in degree of importance and in how they influence pricing decisions.

    North America and Europe are in the midst of a large-scale experiment. Sulfuric and nitric acids have acidified soils, lakes, and streams, thereby stressing or killing terrestrial and aquatic biota. It is therefore critical to measure and to understand the recovery of complex ecosystems in response to decreases in acidic deposition. Fortunately, the NADP, CASTNet, and AIRMoN-dry networks are in place to measure anticipated improvements in air quality and in atmospheric deposition. Unfortunately, networks to measure changes in water quality are sparse, and networks to monitor soil, vegetation, and fish responses are even more limited. There is an acute need to assess the response of these resources to decreases in acid loading. It would be particularly valuable to assess the recovery of aquatic biota - which respond directly to acid stress - to changes in surface water chemistry (Gunn and Mills 1998). We used long-term research from the HBEF and other sites across the northeastern United States to synthesize data on the effects of acidic deposition and to assess ecosystem responses to reductions in emissions. On the basis of existing data, it is clear that in the northeastern United States ??? reductions of SO2 emissions since 1970 have resulted in statistically significant decreases in SO42- in wet and bulk deposition and in surface waters ??? emissions of NOX and concentrations of NO3- in wet and bulk deposition and in surface waters have shown no increase or decrease since the 1980s ??? estimates of NH3 emissions are uncertain, although atmospheric deposition of NH4+ remains important for forest management and stream NO3- loss ??? acidic deposition has accelerated the leaching of base cations from soils, thus delaying the recovery of ANC in lakes and streams from decreased emissions of SO2 (at the HBEF the available soil Ca pool appears to have declined 50% over the past 50 years) ???sulfur and N from atmospheric deposition have accumulated in forest soils across

    Surveillance of pregnancies in women living with HIV is carried out on a national basis in the United Kingdom (UK) through the National Study of HIV in Pregnancy and Childhood. There are currently around 1100-1200 HIV-exposed uninfected (HEU) infants born every year in the UK, where vertical transmission of HIV now occurs in fewer than 5 in every 1000 pregnancies. By the end of 2014, there was a cumulative total of more than 15,000 HEU children with any combination antiretroviral therapy (cART) exposure and more than 5000 with cART exposure from conception in the UK. HEU infants are increasingly being exposed to newer antiretroviral drugs for which less is known regarding both short- and long-term safety. In this commentary, we describe the approaches that have been taken to explore health outcomes in HEU children born in the UK. This includes the Children exposed to AntiRetroviral Therapy (CHART) Study, which was a consented follow-up study carried out in 2002-2005 of HEU children born in 1996-2004. The CHART Study showed that 4% of HEU children enrolled had a major health or development problem in early childhood; this was within expected UK norms, but the study was limited by small numbers and short-term follow-up. However, the problems with recruitment and retention that were encountered within the CHART Study demonstrated that comprehensive, clinic-based follow-up was not a feasible approach for long-term assessment of HEU children in the UK. We describe an alternative approach developed to monitor some aspects of their long-term health, involving the "flagging" of HEU infants for death and cancer registration with the UK Office for National Statistics. Some of the ethical concerns regarding investigation of long-term outcomes of in utero and perinatal exposure to antiretrovirals, including those relating to consent and confidentiality, are also discussed.

    Historical and geological data indicate that significant changes can occur in the Earth's climate on time scales ranging from years to millennia. In addition to natural climatic change, climatic changes may occur in the near future due to increased concentrations of carbon dioxide and other trace gases in the atmosphere that are the result of human activities. International research efforts using atmospheric general circulation models (AGCM's) to assess potential climatic conditions under atmospheric carbon dioxide concentrations of twice the pre-industrial level (a '2 X CO2' atmosphere) conclude that climate would warm on a global basis. However, it is difficult to assess how the projected warmer climatic conditions would be distributed on a regional scale and what the effects of such warming would be on the landscape, especially for temperate mountainous regions such as the Western United States. In this report, we present a strategy to assess the regional sensitivity to global climatic change. The strategy makes use of a hierarchy of models ranging from an AGCM, to a regional climate model, to landscape-scale process models of hydrology and vegetation. A 2 X CO2 global climate simulation conducted with the National Center for Atmospheric Research (NCAR) GENESIS AGCM on a grid of approximately 4.5o of latitude by 7.5o of longitude was used to drive the NCAR regional climate model (RegCM) over the Western United States on a grid of 60 km by 60 km. The output from the RegCM is used directly (for hydrologic models) or interpolated onto a 15-km grid (for vegetation models) to quantify possible future environmental conditions on a spatial scale relevant to policy makers and land managers.

    The teenage pregnancy unit's strategy for dealing with the increasing problem of unwanted pregnancy is rather prescriptive and simplistic for such a complex problem. It is not surprising that despite its recent recommendations, the problem has worsened. It is ludicrous to promote efficient ways to provide oral contraceptive pills to teenagers when good evidence of its inconsistent use among this age group is common knowledge. In addition, increasing access to emergency contraception could undermine teenagers' perception of the importance of commitment in relationships and thus send them a wrong message. This paper reviews the available evidence on the subject and highlights some good practices from other parts of the western world, which have not been incorporated into the UK strategy. It challenges the various stakeholders to show better commitment by providing a more rigorous and effective strategy.

    Full Text Available The goal of this article is to discuss the significance of human capital in the process of building the strategy of social responsibility and the role of personnel marketing in the process. Dynamically changing social environment has enforced a new way of looking at non-material resources. Organizations have understood that it is human capital and social competences that have a significant impact on the creation of an organization’s value, generating profits, as well as gaining competitive advantage in the 21st century. Personnel marketing is now a key element in the process of implementation of the CSR concept and building the value of contemporary organizations, especially such unique organizations as scientific units. In this article you will find a discussion concerning the basic values regarded as crucial by the Central Mining Institute in the context of their significance for the paradigm of social responsibility. Such an analysis was carried out on the basis of the experiences of Central Mining Institute (GIG in the development of strategic CSR, which takes into consideration the specific character of the Institute as a scientific unit.

    Full Text Available Context: The role of hand hygiene in preventing health care associated infections (HCAIs has been clearly established. However, compliance rates remain poor among health care personnel. Aims: a To investigate the health care workers′ hand hygiene compliance rates in the intensive care unit (ICU, b to assess reasons for non-compliance and c to study the efficacy of a multimodal intervention strategy at improving compliance. Settings: A mixed medical-surgical ICU of a tertiary level hospital. Design: A before-after prospective, observational, intervention study. Materials and Methods: All health care personnel who came in contact with patients in the ICU were observed for their hand hygiene compliance before and after a multimodal intervention strategy (education, posters, verbal reminders and easy availability of products. A self-report questionnaire was also circulated to assess perceptions regarding compliance. Statistical analysis was done using c2 test or Fisher exact test (Epi info software. Results: Hand hygiene compliance among medical personnel working in the ICU was 26% and the most common reason cited for non-compliance was lack of time (37%. The overall compliance improved significantly following the intervention to 57.36% (P<0.000. All health care worker groups showed significant improvements: staff nurses (21.48-61.59%, P<0.0000, nursing students (9.86-33.33%, P<0.0000, resident trainees (21.62-60.71%, P<0.0000, visiting consultants (22-57.14%, P=0.0001, physiotherapists (70-75.95%, P=0.413 and paramedical staff (10.71-55.45%, P< 0.0000. Conclusions: Hand hygiene compliance among health care workers in the ICU is poor; however, intervention strategies, such as the one used, can be useful in improving the compliance rates significantly.

    Full Text Available This paper presents an empirical investigation to study the relationship between social capital and organizational commitment. The study considers the relationship between social capital with three components of organizational commitment; namely, affective commitment, continuous and normative commitment. The study has been applied among a sample of 292 regular employees who worked for an Iranian bank located in city of Tehran, Iran. The implementation of Pearson correlation has indicated that there were positive and meaningful relationships between social capital and affective commitment (r = 0.197, Sig. = 0.01, continuous (r = 0.308, Sig. = 0.01 and normative commitment (r = 0.423, Sig. = 0.01. In addition, the study has detected that women had more commitment on their organization than men did. The proposed study of this paper has also considered a regression model where organizational commitment is dependent variable and trust and communication are considered as independent variables. According to the results of regression analysis, an increase of one unit in trust and social capital communication will increase organizational commitment by 0.189 and 0.204, respectively.

    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.

    Groenewegen Peter P

    2011-05-01

    Full Text Available Abstract Background We need to know the scale and underlying causes of surgical adverse events (AEs in order to improve the safety of care in surgical units. However, there is little recent data. Previous record review studies that reported on surgical AEs in detail are now more than ten years old. Since then surgical technology and quality assurance have changed rapidly. The objective of this study was to provide more recent data on the incidence, consequences, preventability, causes and potential strategies to prevent AEs among hospitalized patients in surgical units. Methods A structured record review study of 7,926 patient records was carried out by trained nurses and medical specialist reviewers in 21 Dutch hospitals. The aim was to determine the presence of AEs during hospitalizations in 2004 and to consider how far they could be prevented. Of all AEs, the consequences, responsible medical specialty, causes and potential prevention strategies were identified. Surgical AEs were defined as AEs attributable to surgical treatment and care processes and were selected for analysis in detail. Results Surgical AEs occurred in 3.6% of hospital admissions and represented 65% of all AEs. Forty-one percent of the surgical AEs was considered to be preventable. The consequences of surgical AEs were more severe than for other types of AEs, resulting in more permanent disability, extra treatment, prolonged hospital stay, unplanned readmissions and extra outpatient visits. Almost 40% of the surgical AEs were infections, 23% bleeding, and 22% injury by mechanical, physical or chemical cause. Human factors were involved in the causation of 65% of surgical AEs and were considered to be preventable through quality assurance and training. Conclusions Surgical AEs occur more often than other types of AEs, are more often preventable and their consequences are more severe. Therefore, surgical AEs have a major impact on the burden of AEs during hospitalizations

    A typical approach to the synthesis/design optimization of energy systems is to only use steady state operation and high efficiency (or low total life cycle cost at full load as the basis for the synthesis/design. Transient operation as reflected by changes in power demand, shut-down, and start-up are left as secondary tasks to be solved by system and control engineers once the synthesis/design is fixed. However, start-up and shut-down may be events that happen quite often and, thus, may be quite important in the creative process of developing the system. This is especially true for small power units used in transportation applications or for domestic energy supplies, where the load demand changes frequently and peaks in load of short duration are common. The duration of start-up is, of course, a major factor which must be considered since rapid system response is an important factor in determining the feasibility of solid oxide fuel cell (SOFC based auxiliary power units (APUs. Start-up and shut-down may also significantly affect the life span of the system due to thermal stresses on all system components. Therefore, a proper balance must be struck between a fast response and the costs of owning and operating the system so that start-up or any other transient process can be accomplished in as short a time as possible yet with a minimum in fuel consumption.

    In this research work we have been studying the effects of control laws and strategies and transients on system performance. The results presented in this paper are based on a set of transient models developed and implemented for the components of a 5 kWe net power SOFC based APU and for the high-fidelity system which results from their integration. The simulation results given below are for two different start-up approaches: one with steam recirculation and component pre-heating and the second without either. These start-up simulations were performed for fixed values of a number of

    Full Text Available The increasing prevalence of chronic diseases throughout the world is an undeniable phenomenon; 395,000 deaths occurred in Iran in 2014 and about 76% of them were related to chronic diseases.1 Cancer is one of the chronic diseases that are progressing rapidly. In Iran, cancer is known as the third cause of death. Adult morbidity rate of cancer in different regions of Iran is estimated 48-112 cases per million people among the females and 51-144 cases per million people among the males.2 Also, mortality rate related to cancer was about 53500 people in 2014.3 In fact, 13% of all deaths related to chronic diseases are caused by cancer1 and the majority of cancer patients expire in the intensive care units (ICU, whereas bed occupancy of ICUs is in crises, being about 100% in Iran. For each ICU bed, 4 people are applicants. In this situation, firstly, a number of patients do not have access to the ICU beds, and secondly, because of the need to ICU beds, the admitted patients in ICU wards are discharged earlier than the standard time for each disease. According to the head of the Intensive Care association, the shortage of ICU beds is about ten thousand in Iran, whereas setting up each ICU bed requires a high cost.4 In the current condition, due to the high cost and shortage of nurses in Iran, setting up of ICU beds is a challenge for the health system. WHO introduced home-based palliative care to improve the quality of life, quality of care, quality of death and patient satisfaction; decrease burnout in staffing and mortality in hospitals; reduce the cost, accept end of life as live days; neither accelerate death nor prolong life; consider all dimensions of human; help the patients to be active until the time of death; help the patient’s family to cope with the disease and loss of patient; and release the beds in hospitals.5 Although hospital beds are considered for healing the patients not a hospice for them, the majority of cancer patients die in

    Large-scale grid-integration of new energy sources such as wind power generation and so on leads to new problems in secure and stable operation of traditional power grids. For a hybrid power grid containing thermal power plants, wind farms and energy storage equipments, by means of constructing a unit commitment model and the stochastic property of wind power output uncertainty is simulated by scenario tree. Leading chaos embedded particle swarm optimization (CEPSO) into scenario reduction algorithms (SRA) the results of stochastic simulation and the ability to search the optimal solution are improved. Taking a hybrid power system composed of a wind farm and a 10-machine system as simulation example, simulation results show that the obtained unit commitment scheme can dispatch as many wind power units as possible and the operational cost of thermal generation units can be reduced to suit to the demand of energy conservation and emission reduction.%  风电等新能源发电机组的大规模并网,对传统电力系统的安全稳定运行带来了新的问题。研究了一种含有风−火−储联合运行的混合电力系统,通过构建机组组合问题模型,利用情景树方法模拟风电出力的不确定性的随机特性,将混沌群粒子优化算法引入情景约简算法,改善随机模拟结果和提高最优解的搜寻能力。算例分析结果表明,得到的机组组合方案能够尽量多调度风电机组,降低火电机组的运行成本,适应节能减排工作需要。

    Nurse-physician collaboration involves healthcare operators from different professions working together. The dual identity model predicts that nurse-physician interprofessional collaboration could improve if these operators feel they belong to both their professional category and care unit. This study tested this prediction by analyzing the effect of professional and team commitments on interprofessional collaboration between nurses and physicians in a hospital based in Northern Italy. A cross-section questionnaire survey was administered to 270 nurses and 95 physicians. Results indicate that interprofessional collaboration is positively affected by team commitment, while professional commitment had no effect. In accordance with the dual identity model, results indicate that interprofessional collaboration is higher when: (i) both professional and team commitment is high, and (ii) when team commitment is high and professional commitment is low. These results support dual identity model predictions and suggest that interprofessional collaboration can be increased by bolstering both team and professional commitment of nurses and physicians.

  3. Commitment to self-rewards

    2009-01-01

    Self-administered rewards are ubiquitous. They serve as incentives for personal accomplish¬ments and are widely recommended as tools for overcoming self-control problems. However, it seems puzzling why self-rewards can work: the prospect of a reward has a motivating force only if the threat of self-denial of the reward after low performance is credible. We explain how a rational forward-looking individual may achieve commitment to self-rewards, by applying Köszegi and Rabin's (2006) model of ...

    The authors examined the relationships between perceived organizational support, organizational commitment, commitment to customers, and service quality in a fast-food firm. The research design matched customer responses with individual employees' attitudes, making this study a true test of the service provider-customer encounter. On the basis of a sample of matched employee-customer data (N = 133), hierarchical linear modeling analyses revealed that perceived organizational support had both a unit-level and an employee-level effect on 1 dimension of service quality: helping behavior. Contrary to affective organizational commitment, affective commitment to customers enhanced service quality. The 2 sub-dimensions of continuance commitment to the organization--perceived high sacrifice and perceived lack of alternatives--exerted effects opposite in sign: The former fostered service quality, whereas the latter reduced it. The implications of these findings are discussed within the context of research on employee-customer encounters.

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

    Directory of Open Access Journals (Sweden)

    2010-12-01

    relationships exist between all the motivational factors and satisfaction, as well as with commitment. The strongest positive relationships exist between the independent variable job interest and importance and both the dependent variables. The weakest relationships exist between the independent variable rewards and both the dependent variables. Levels of satisfaction and commitment should continually be developed and improved through management training about the application of motivational factors. Small businesses should implement the motivational factors discussed in this research in creative ways, in order to have a positive effect on the satisfaction and commitment levels of employees.Originality and value of the research : This research focused on what small business managers should concentrate on when motivating their employees. Small business managers should also realise that motivation cannot be separated from employee satisfaction and commitment. The value of the research is that when small business managers pay more attention to these factors as identified in this study, it may lead to better business performance in the long run. With regard to the originality of this research, previous research has focused mainly on motivational theories without reaching a conclusion or highlighting possible strategies that could be used by small businesses to motivate employees.

    To compare the results of quality monitoring after the implementation of improvement strategies in the respiratory intensive care unit (RICU). A prospective, comparative, longitudinal and interventional study was carried out. The RICU of Hospital General de México (Mexico). All patients admitted to the RICU from March 2012 to March 2013. An evidence-based bundle of interventions was implemented in order to reduce the ratios of three quality indicators: non-planned extubation (NPE), reintubation, and ventilator-associated pneumonia (VAP). NPE, reintubation and VAP ratios. A total of 232 patients were admitted, with a mean age of 49.5±17.8years; 119 (50.5%) were woman. The mean Simplified Acute Physiology Score (SAPS-3) was 49.8±17, and the mean Sequential Organ Failure Assessment (SOFA) score was 5.3±4.1. The mortality rate in the RICU was 38.7%. The standardized mortality ratio was 1.50 (95%CI: 1.20-1.84). An improved ratio was observed for reintubation and NPE indicators compared to the ratios of the previous 2011 cohort: 1.6% vs. 7% (P=.02) and 8.1 vs. 17 episodes per 1000 days of mechanical ventilation (P=.04), respectively. A worsened VAP ratio was observed: 18.4 vs. 15.1 episodes per 1000 days of mechanical ventilation (P=.5). Quality improvement is feasible with the identification of areas of opportunity and the implementation of strategies. Nevertheless, the implementation of a bundle of preventive measures in itself does not guarantee improvements. Copyright © 2013 Elsevier España, S.L.U. and SEMICYUC. All rights reserved.

    Focus groups were used to identify opportunities, barriers, and strategies for increased utilization of forest biomass in the Southern United States. The groups were based on the seven critical components in the bioenergy and bio-based products value chain, as identified by the International Energy Agency (IEA) Bioenergy Task 31 ''Biomass Production for Energy from Sustainable Forestry.'' These components include sustainable biomass production, sustainable forest operations, product delivery logistics, manufacturing and energy production, environmental sustainability, consumer demand, and rural economic development. Participants included handpicked experts from each of the seven component areas. Six common themes emerged from the focus groups. Market creation, infrastructure development, community engagement, incentives, collaboration, and education will all be critical to the successful development of the biomass industry. The forest industry, the energy industry, academia, extension personnel, and rural communities should collaborate together to support research, policy issues, and educational programs that enhance the efficiency of current forest biomass operations and promote the use of forest biomass for bioenergy.

    Full Text Available Objective: To identify the prevalence of diabetic retinopathy (DR in patients served by the Family Health Strategy (FHS of Ananindeua, Brazil. Methods: This was a cross-sectional study with 40 patients with diabetes mellitus (DM enrolled in the HIPERDIA program and assisted by the FHS of Ananindeua. Those selected were subjected to a standardized questionnaire at home and answered questions about the knowledge, outcomes and complications of DM and DR, and socioeconomic data. In the next step, a volunteer ophthalmologist performed ophthalmoscopy and found those with DR, who were sent to a specialized center to receive treatment. Of these patients, 9 were excluded because they did not attend the unit to perform ophthalmoscopy. Results: The prevalence of DR was found to be 40.7%; however, 4 patients had impaired their analysis due to the presence of cataracts, so it was only possible to do evaluation in 27. Factors associated with DR, after analysis of the variables were the time to the patients be aware of the diagnosis of DM, type of DM and non-proliferative DR. Conclusion: This pilot study underscores the importance of primary care in monitoring diabetic patients and guidance to the professionals of public health about the need for periodic referral of diabetic patients to ophthalmologists.

  14. The meaning of postponed motherhood for women in the United States and Sweden: aspects of feminism and radical timing strategies.

    Welles-Nyström, B

    1997-01-01

    This exploratory study considered certain psychosocial, medical, and cultural aspects of the phenomenon of postponed motherhood for one cohort of white women born between 1947 and 1953 in Sweden and the United States. A cross-cultural comparison was made of the experience of pregnancy and the early perinatal period in 15 American and 16 Swedish women to find out (a) whether timing decisions reflected the influence of feminist ideology toward a reproductive strategy radically different from the conventional one, and (b) whether the pattern of delayed motherhood was culture specific. Results indicated that the patterns of delayed motherhood were culture specific. Feminist ideology clearly influenced the timing of the American women's first birth but was evident in Sweden. Women in the U.S. exhibited more nonconventional behaviors and attitudes, whereas Swedish women were more conventional. However, the husbands in both groups were remarkably similar in infant caretaking behaviors, regardless of culture and level of education attainment. These findings indicate postponed motherhood has different meanings in the cultural context of these two Western industrialized societies.

    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.

  18. Revealing ontological commitments by magic.

    Science.gov (United States)

    Griffiths, Thomas L

    2015-03-01

    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.

    2009-11-15

    Purpose: The aim of the study is to examine factors associated with the goal commitment of radiography departments' staff. The associations studied are (1) organizational change, (2) work-related factors, (3) psychosocial work environment, and (4) intention to leave. Method: The follow-up study was performed between 2005 and 2007 in co-operation with 10 radiography departments of two Finnish municipalities. In 2005 the response rate was 60% (n = 97/163) and in 2007 it was 49% (n = 73/150). Results: The goal commitment had dropped during the organizational change from 3.96 in 2005 to 3.60 in 2007 (scale 1-5) (p = 0.001). Best predictors for the goal commitment of radiography departments' staff were having children (OR 4.4) and perceiving functional environment clearly (OR 2.6). Correlation between the goal commitment and intention to leave of the staff was -0.32 (p = 0.01). Conclusion: From the viewpoint of the commitment of the radiography departments' staff, the trend of uniting quite independent health care units into larger entities seems not to be beneficial. This study reveals that commitment to one's work unit is most of all a question of stability and job security. This is a fact the leadership of the radiography departments should take into account, appreciate and support to assure the tenure and productivity of their workforce.

    Full Text Available Objective to prove the necessity to take into account the influence of emotions on decision making to describe a combined model of the decision making process which unites rational and irrational components of choice in crime commitment. Methods dialectic systemic historicallegal formaljuridical methods summarization. Results the paper gives a complex analysis of the criminal decisionmaking process and reveals the factors increasing the probability of antisocial actions. The value of the combined cognitiveemotive model is that emotions can give more significant information to the decisionmaker than reasoning. Scientific novelty the author proposes a theory of decision making which says that a person chooses to act or not to act under hedonistic or moral emotions while the irrelevant emotions are increased and the relevant ones are suppressed by cognitive and situational factors serving as a basis for criminal decision making. Practical significance studying the role of emotions in the criminal and noncriminal decision making will significantly contribute to the development of criminology. The research results will be useful for researchers and lawenforcement bodies as well as for all those who are interested in the issues of crime control and prevention.

    The protozoan Trypanosoma cruzi is the causative agent of Chagas disease, a major public health problem in Latin America. This parasite has a complex population structure comprised by six or seven major evolutionary lineages (discrete typing units or DTUs) TcI-TcVI and TcBat, some of which have apparently resulted from ancient hybridization events. Because of the existence of significant biological differences between these lineages, strain characterization methods have been essential to study T. cruzi in its different vectors and hosts. However, available methods can be laborious and costly, limited in resolution or sensitivity. In this study, a new genotyping strategy by real-time PCR to identify each of the six DTUs in clinical blood samples have been developed and evaluated. Two nuclear (SL-IR and 18S rDNA) and two mitochondrial genes (COII and ND1) were selected to develop original primers. The method was evaluated with eight genomic DNA of T. cruzi populations belonging to the six DTUs, one genomic DNA of Trypanosoma rangeli, and 53 blood samples from individuals with chronic Chagas disease. The assays had an analytical sensitivity of 1-25fg of DNA per reaction tube depending on the DTU analyzed. The selectivity of trials with 20fg/μL of genomic DNA identified each DTU, excluding non-targets DTUs in every test. The method was able to characterize 67.9% of the chronically infected clinical samples with high detection of TcII followed by TcI. With the proposed original genotyping methodology, each DTU was established with high sensitivity after a single real-time PCR assay. This novel protocol reduces carryover contamination, enables detection of each DTU independently and in the future, the quantification of each DTU in clinical blood samples.

    Full Text Available BACKGROUND: Carbapenemase-producing Klebsiella pneumoniae (CPKP has been established as important nosocomial pathogen in many geographic regions. Transmission from patient to patient via the hands of healthcare workers is the main route of spread in the acute-care setting. METHODOLOGY/PRINCIPAL FINDINGS: Epidemiological and infection control data were recorded during a prospective observational study conducted in a surgical unit of a tertiary-care hospital in Greece. Surveillance culture for CPKP were obtained from all patients upon admission and weekly thereafter. The Ross-Macdonald model for vector-borne diseases was applied to obtain estimates for the basic reproduction number R(0 (average number of secondary cases per primary case in the absence of infection control and assess the impact of infection control measures on CPKP containment in endemic and hyperendemic settings. Eighteen of 850 patients were colonized with CPKP on admission and 51 acquired CPKP during hospilazation. R(0 reached 2 and exceeded unity for long periods of time under the observed hand hygiene compliance (21%. The minimum hand hygiene compliance level necessary to control transmission was 50%. Reduction of 60% to 90% in colonized patients on admission, through active surveillance culture, contact precautions and isolation/cohorting, in combination with 60% compliance in hand hygiene would result in rapid decline in CPKP prevalence within 8-12 weeks. Antibiotics restrictions did not have a substantial benefit when an aggressive control strategy was implemented. CONCLUSIONS/SIGNIFICANCE: Surveillance culture on admission and isolation/cohorting of colonized patients coupled with moderate hand hygiene compliance and contact precautions may lead to rapid control of CPKP in endemic and hyperendemic healthcare settings.

    This article discusses the design,sampling strategy, implementation,and data analytic processes of the DSM-5 Field Trials. The DSM-5 Field Trials were conducted by using a test-retest reliability design with a stratified sampling approach across six adult and four pediatric sites in the United States and one adult site in Canada. A stratified random sampling approach was used to enhance precision in the estimation of the reliability coefficients. A web-based research electronic data capture system was used for simultaneous data collection from patients and clinicians across sites and for centralized data management.Weighted descriptive analyses, intraclass kappa and intraclass correlation coefficients for stratified samples, and receiver operating curves were computed. The DSM-5 Field Trials capitalized on advances since DSM-III and DSM-IV in statistical measures of reliability (i.e., intraclass kappa for stratified samples) and other recently developed measures to determine confidence intervals around kappa estimates. Diagnostic interviews using DSM-5 criteria were conducted by 279 clinicians of varied disciplines who received training comparable to what would be available to any clinician after publication of DSM-5.Overall, 2,246 patients with various diagnoses and levels of comorbidity were enrolled,of which over 86% were seen for two diagnostic interviews. A range of reliability coefficients were observed for the categorical diagnoses and dimensional measures. Multisite field trials and training comparable to what would be available to any clinician after publication of DSM-5 provided “real-world” testing of DSM-5 proposed diagnoses.

  6. The Northeastern United States Energy-Water Nexus: Climate Change Impacts and Alternative Water Management Strategies for the Power Sector

    2014-12-01

    The Northeastern United States (NE) relies heavily on thermoelectric power plants (90% of total capacity) to provide electricity to more than 70 million people. This region's power plants require consistent, large volumes of water at sufficiently cold temperatures to generate electricity efficiently, and withdraw approximately 10.5 trillion gallons of water annually. Previous findings indicate that assessments of future electricity pathways must account for water availability, water temperature and the changing climate, as changes in these conditions may limit operational efficiency in the future. To account for such electric system vulnerabilities, we have created a link between an electricity system capacity expansion model (ReEDS) and a hydrologic model that is coupled to a power plant simulation model (FrAMES-TP2M) that allows for a new approach to analyze electricity system development, performance, and environmental impacts. Together, these coupled tools allow us to estimate electricity development and operations in the context of a changing climate and impacts on the seasonal spatial and temporal variability of water resources, downstream thermal effluents that cause plant-to-plant interferences and harm aquatic habitat, economic costs of water conservation methods and associated carbon emissions. In this study, we test and compare a business-as-usual strategy with three alternative water management scenarios that include changes in cooling technologies and water sources utilized for the years 2014-2050. Results of these experiments can provide useful insight into the feasibility of the electricity expansion scenarios in terms of associated water use and thermal impacts, carbon emissions, the cost of generating electricity, and also highlight the importance of accounting for water resources in future power sector planning and performance assessments.

    Skilled readers by definition are strategic; they are able to use a repertoire of reading strategies , flexibly and in meaningful combinations , to achieve their reading comprehension goals . Thus , one of the aims of foreign and second language (L2) reading curricula should be to move students toward becoming more strategic readers . This curricular orientation can be best achieved when a strong commitment is made to strategic-reader training as a regular and consistent component of instruction across the curriculum . To explore this stance , we examine the reading strategies used by skilled readers , contrast teaching strategies with training strategic readers ( i .e . , strategic-reader training) , and examine five strategic-reader training approaches from first language contexts that can be adapted by L2 professionals to enhance the reading instruction offered in their L 2 classes . The five approaches targeted for exploration include Directed Reading-Thinking Activity , Reciprocal Teaching , Transactional Strategies Instruction , Questioning the Author , and Concept-Oriented Reading Instruction . Though distinct from one another , they all acknowledge the importance of explicit explanations about strategies (or reminders about the use of select strategies) , teacher modeling , scaffolded tasks , active student engagement , student practice , classroom discussions of strategy use , and the gradual release of responsibility to students who eventually decide for themselves (and/or with peers) when , where , and why to use which strategies to achieve their comprehension goals . We conclude with a discussion of the challenges , and suggestions for overcoming them , that L 2 teachers and students often face in making a commitment to strategic-reader training .

  8. The multimillennial sea-level commitment of global warming.

    Global mean sea level has been steadily rising over the last century, is projected to increase by the end of this century, and will continue to rise beyond the year 2100 unless the current global mean temperature trend is reversed. Inertia in the climate and global carbon system, however, causes the global mean temperature to decline slowly even after greenhouse gas emissions have ceased, raising the question of how much sea-level commitment is expected for different levels of global mean temperature increase above preindustrial levels. Although sea-level rise over the last century has been dominated by ocean warming and loss of glaciers, the sensitivity suggested from records of past sea levels indicates important contributions should also be expected from the Greenland and Antarctic Ice Sheets. Uncertainties in the paleo-reconstructions, however, necessitate additional strategies to better constrain the sea-level commitment. Here we combine paleo-evidence with simulations from physical models to estimate the future sea-level commitment on a multimillennial time scale and compute associated regional sea-level patterns. Oceanic thermal expansion and the Antarctic Ice Sheet contribute quasi-linearly, with 0.4 m °C(-1) and 1.2 m °C(-1) of warming, respectively. The saturation of the contribution from glaciers is overcompensated by the nonlinear response of the Greenland Ice Sheet. As a consequence we are committed to a sea-level rise of approximately 2.3 m °C(-1) within the next 2,000 y. Considering the lifetime of anthropogenic greenhouse gases, this imposes the need for fundamental adaptation strategies on multicentennial time scales.

  9. Optimal Deadline Scheduling with Commitment

    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...

  10. Prosodic form and parsing commitments.

    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.

    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.

    The commitment of employees is affected by several factors, including factors related to the organizational climate. The aim of this study was to investigate the relationship between organizational commitment of nurses and the organizational climate in hospital settings. A cross-sectional study was conducted in 2014 at two teaching hospitals in Yazd, Iran. A total of 90 nurses in these hospitals participated. We used stratified random sampling of the nursing population. The required data were gathered using two valid questionnaires: Allen and Meyer's organizational commitment standard questionnaire and Halpin and Croft's Organizational Climate Description Questionnaire. Data analysis was done through SPSS 20 statistical software (IBM Corp., Armonk, NY, USA). We used descriptive statistics and Pearson's correlation coefficient for the data analysis. The findings indicated a positive and significant correlation between organizational commitment and organizational climate (r = 0.269, p = 0.01). There is also a significant positive relationship between avoidance of organizational climate and affective commitment (r = 0.208, p = 0.049) and between focus on production and normative and continuance commitment (r = 0.308, p = 0.003). Improving the organizational climate could be a valuable strategy for improving organizational commitment.

    Introduction Presence of committed personnel in each organization not only reduces their absenteeism, delays, and displacements but also leads to a dramatic increase in performance and efficiency of an organization, mental freshness of employees, better manifestation of noble objectives, and organizational mission as well as fulfillment of personal goals. Therefore, the purpose of this study was to determine the relationship between organizational culture and organizational commitment of employees in administrative units of health care centers in the cities of Hamedan Province based on the Denison model in 2015. Methods In this cross-sectional study, 177 employees in administrative units of health care centers in the cities of Hamedan Province were selected by a multistage stratified sampling method. The data collection instruments included the standardized Denison organizational culture survey and organizational commitment questionnaire by Meyer and Allen. Data were analyzed by IBM-SPSS version 21 using descriptive statistics and Pearson product-moment coefficient. Results Among the 12 indicators of organizational culture, the highest mean scores were assigned to empowerment (16.74), organizational learning (16.41), vision (16.4), and strategic direction (16.35); respectively. Furthermore, the indicators of capability development (14.2), core values (15.31), team orientation (15.45), and goals (15.46) received the lowest mean scores in this respect. Among the four dimensions of organizational culture, the highest mean score was related to “mission” in organizational culture and the lowest score was associated with “involvement.” Meyer and Allen’s organizational commitment model also had three components in which affective commitment in this study obtained the highest score (26.63) and continuance commitment received the lowest score (24.73). In this study, there was a significant correlation between all the components of organizational culture and

    2010-06-01

    This study examines the Noyce Program, which provides scholarships for STEM majors in return for teaching in high need schools. The perceptions of 555 scholarship recipients were investigated using hierarchical cluster analysis, confirmatory factor analysis, and Rasch analysis to determine how the scholarship influenced their commitments to teaching in high need schools. The analyses indicated that recipients perceived the scholarship in two ways: it influenced their commitment to complete their certification program and to teach in high need schools. Implications for teacher education programs include that recruitment strategies should identify candidates who are committed to teaching in high need schools and programs should provide experiences to encourage this commitment not just to become certified.

  3. Acceptance and commitment therapy - pathways for general practitioners.

    Smout, Matthew

    2012-09-01

    Acceptance and commitment therapy (ACT) focuses on helping patients to behave more consistently with their own values and apply mindfulness and acceptance skills to their responses to uncontrollable experiences. This article presents an overview of ACT, its evidence base and how general practitioners can apply ACT consistent practice in the primary care setting. It describes pathways for general practitioners to develop further expertise in the approach. Acceptance and commitment therapy has been associated with improved outcomes in patients with chronic pain (comparable to cognitive behaviour therapy) and several studies suggest that it may be useful in patients with mild to moderate depression. Preliminary evidence of benefit has also been shown in the setting of obsessive-compulsive disorder, psychosis, smoking, tinnitus, epilepsy and emotionally disordered eating after gastric band surgery. Acceptance and commitment therapy starts with a discussion about what the patient wants and how they have tried to achieve these aims. Strategies previously used to avoid discomfort are discussed. Psychoeducation in ACT involves metaphors, stories and experiential exercises to demonstrate the uncontrollability and acceptability of much psychological experience. In its final phase, ACT resembles traditional behaviour therapy consisting of goal setting and graduated activity scheduling toward goals directed by values.

  4. Attaining organizational commitment across different generations of nurses.

    Carver, Lara; Candela, Lori

    2008-11-01

    To inform nurse managers about the generational differences that exist among nurses, how it affects the work environment and how this information can be used to encourage organizational commitment. Every person is born into a generational cohort of peers who experience similar life experiences that go on to shape distinct generational characteristics. Thanks to delayed retirements, mid-life career changes, job re-entry and a small but significant group of younger graduates, the nursing profession is now experiencing four generations in the workforce: Veterans, Baby Boomers, Generation X and the Millennial Generation. At the same time, the literature on organizational commitment is expanding and can provide a compelling context through which to view generational differences among nurses. As part of an overall strategy to increase organizational commitment, consideration of generational differences in nurses can be helpful in leading to increased job satisfaction, increased productivity and decreased turnover among staff. In the face of the global nursing shortage, managers should increase their knowledge of generational diversity just as they have with ethnic and cultural diversity in the past. Understanding how to relate to the different generations and tap into their individual strengths can lead to improved nursing work environments.

    Full Text Available In today’s competitive electricity market, it is not possible to settle all contracted transactions of power because of congestion in transmission lines. Usually, the independent system operator seeks to eliminate congestion by rescheduling output power of the generators. But all generators may not have the same effect (sensitivity on the power flow of the congested lines, so this is not an economical way to reschedule output power of all generators for managing congestion. Therefore, in this paper, active power generator sensitivity factor of the generators to the congested lines have been utilized to ascertain the number of generators participating in congestion management.

    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.

    O'Donnell, Carol Lynn

    This study examined whether fidelity of implementation to reform-based instructional strategies embedded in a middle school physical science curriculum unit developed by the Harvard-Smithsonian Center for Astrophysics moderated the causal relationship between curriculum condition and classroom mean achievement in a quasi-experiment testing the effectiveness of the unit. The study sample included 48 6th grade science classrooms selected randomly from 8 Montgomery County Public Schools middle schools, assigned randomly to either the treatment or comparison condition in the Scaling up Curriculum for Achievement, Learning, and Equity Project (SCALE-0) quasi-experiment of The George Washington University. This dissertation was a secondary analysis of SCALE-uP's 2005-2006 fidelity of implementation data collected with the Instructional Strategies Classroom Observation Protocol (ISCOP), which captured whether the Project 2061 instructional strategies rated Satisfactory or Excellent in the ARIES: Exploring Motion and Forces (M&F) treatment unit were present during implementation in treatment and comparison classrooms. ISCOP Likert-like scores for each classroom were subjected to Rasch analysis; rating scale diagnostics, category collapsing, and fit statistics were used to develop a reliable continuous fidelity of implementation measure for each classroom. Results from hierarchical multiple regression analysis performed on the fidelity of implementation measures indicated that when controlling for prior knowledge, fidelity of implementation to the Project 2061 instructional strategies rated Satisfactory or Excellent in M&F moderated the causal relationship between science curriculum condition and classroom mean achievement. Follow-up post hoc analyses at two select fidelity measures indicated that treatment classrooms with High Fidelity were predicted to have higher classroom mean achievement than comparison classrooms with High Fidelity to the same set of instructional

    Umbilical cord blood (UCB) transplantation is associated with long periods of aplastic anaemia. This undesirable situation is due to the low cell dose available per unit of UCB and the immaturity of its progenitors. To overcome this, we present a cell culture strategy aimed at the expansion of the CD34(+) population and the generation of granulocyte lineage-committed progenitors. Two culture products were produced after either 6 or 14days of in vitro expansion, and their characteristics compared to non-expanded UCB CD34(+) controls in terms of phenotype, colony-forming activity and multilineage repopulation potential in NOD-scid IL2Rγ(null) mice. Both expanded cell products maintained rapid SCID repopulation activity similar to the non-expanded control, but 14-day cultured cells showed impaired long term SCID repopulation activity. The process was successfully scaled up to clinically relevant doses of 89×10(6) CD34(+) cells committed to the granulocytic lineage and 3.9×10(9) neutrophil precursors in different maturation stages. Cell yields and biological properties presented by the cell product obtained after 14days in culture were superior and therefore this is proposed as the preferred production setup in a new type of dual transplant strategy to reduce aplastic periods, producing a transient repopulation before the definitive engraftment of the non-cultured UCB unit. Importantly, human telomerase reverse transcriptase activity was undetectable, c-myc expression levels were low and no genetic abnormalities were found, as determined by G-banding karyotype, further confirming the safety of the expanded product.

  3. IMPROVE THE KINETIC PERFORMANCE OF THE PUMP CONTROLLED CLAMPING UNIT IN PLASTIC INJECTION MOLDING MACHINE WITH ADAPTIVE CONTROL STRATEGY

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The kinetic characteristics of the clamping unit of plastic injection molding machine that is controlled by close loop with newly developed double speed variable pump unit are investigated.Considering the wide variation of the cylinder equivalent mass caused by the transmission ratio of clamping unit and the severe instantaneous impact force acted on the cylinder during the mold closing and opening process, an adaptive control principle of parameter and structure is proposed to improve its kinetic performance. The adaptive correlation between the acceleration feedback gain and the variable mass is derived. The pressure differential feedback is introduced to improve the dynamic performance in the case of small inertia and heavy impact load. The adaptation of sum pressure to load is used to reduce the energy loss of the system. The research results are verified by the simulation and experiment. The investigation method and the conclusions are also suitable for the differential cylinder system controlled by the traditional servo pump unit.

  4. Adult vaccination strategies for the control of pertussis in the United States: an economic evaluation including the dynamic population effects.

    Directory of Open Access Journals (Sweden)

    Laurent Coudeville

    Full Text Available BACKGROUND: Prior economic evaluations of adult and adolescent vaccination strategies against pertussis have reached disparate conclusions. Using static approaches only, previous studies failed to analytically include the indirect benefits derived from herd immunity as well as the impact of vaccination on the evolution of disease incidence over time. METHODS: We assessed the impact of different pertussis vaccination strategies using a dynamic compartmental model able to consider pertussis transmission. We then combined the results with economic data to estimate the relative cost-effectiveness of pertussis immunization strategies for adolescents and adults in the US. The analysis compares combinations of programs targeting adolescents, parents of newborns (i.e. cocoon strategy, or adults of various ages. RESULTS: In the absence of adolescent or adult vaccination, pertussis incidence among adults is predicted to more than double in 20 years. Implementing an adult program in addition to childhood and adolescent vaccination either based on 1 a cocoon strategy and a single booster dose or 2 a decennial routine vaccination would maintain a low level of pertussis incidence in the long run for all age groups (respectively 30 and 20 cases per 100,000 person years. These strategies would also result in significant reductions of pertussis costs (between -77% and -80% including additional vaccination costs. The cocoon strategy complemented by a single booster dose is the most cost-effective one, whereas the decennial adult vaccination is slightly more effective in the long run. CONCLUSIONS: By providing a high level of disease control, the implementation of an adult vaccination program against pertussis appears to be highly cost-effective and often cost-saving.

    Full Text Available Consumer markets have become increasingly competitive. Numerous measures to gauge and predict loyalty and commitment have been developed to assist management in this respect. The marketing literature contains many examples illustrating that longer relationships achieve customer retention, and have been rewarded with a considerable increase in customer net present value. Customer retention is undoubtedly a major contributor to profitability in the long term. Research shows that the most successful measures for achieving customer retention are customer delight, customer satisfaction and customer commitment. This study makes a closer exploration of customer commitment, as measured by the Conversion Model, in the South African motor vehicle industry. The findings highlight the commitment segments of the most popular motor vehicle brands in South Africa, as well the typical marketing strategies for managing the different commitment segments.

    Gershengorn, Hayley B; Kocher, Robert; Factor, Phillip

    2014-02-01

    The business community has developed strategies to ensure the quality of the goods or services they produce and to improve the management of multidisciplinary work teams. With modification, many of these techniques can be imported into intensive care units (ICUs) to improve clinical operations and patient safety. In Part I of a three-part ATS Seminar series, we argue for adopting business management strategies in ICUs and set forth strategies for targeting selected quality improvement initiatives. These tools are relevant to health care today as focus is placed on limiting low-value care and measuring, reporting, and improving quality. In the ICU, the complexity of illness and the need to standardize processes make these tools even more appealing. Herein, we highlight four techniques to help prioritize initiatives. First, the "80/20 rule" mandates focus on the few (20%) interventions likely to drive the majority (80%) of improvement. Second, benchmarking--a process of comparison with peer units or institutions--is essential to identifying areas of strength and weakness. Third, root cause analyses, in which structured retrospective reviews of negative events are performed, can be used to identify and fix systems errors. Finally, failure mode and effects analysis--a process aimed at prospectively identifying potential sources of error--allows for systems fixes to be instituted in advance to prevent negative outcomes. These techniques originated in fields other than health care, yet adoption has and can help ICU managers prioritize issues for quality improvement.

    2011-01-01

    Nurse researchers and educators often engage in outreach to narrowly defined populations. This article offers examples of how variations on the snowball sampling recruitment strategy can be applied in the creation of culturally appropriate, community-based information dissemination efforts related to recruitment to health education programs and research studies. Examples from the primary author’s program of research are provided to demonstrate how adaptations of snowball sampling can be effectively used in the recruitment of members of traditionally underserved or vulnerable populations. The adaptation of snowball sampling techniques, as described in this article, helped the authors to gain access to each of the more vulnerable population groups of interest. The use of culturally sensitive recruitment strategies is both appropriate and effective in enlisting the involvement of members of vulnerable populations. Adaptations of snowball sampling strategies should be considered when recruiting participants for education programs or subjects for research studies when recruitment of a population based sample is not essential.

    2016-07-01

    Teenage pregnancy is an issue of inequality affecting the health, well-being, and life chances of young women, young men, and their children. Consequently, high levels of teenage pregnancy are of concern to an increasing number of developing and developed countries. The UK Labour Government's Teenage Pregnancy Strategy for England was one of the very few examples of a nationally led, locally implemented evidence-based strategy, resourced over a long duration, with an associated reduction of 51% in the under-18 conception rate. This article seeks to identify the lessons applicable to other countries. The article focuses on the prevention program. Drawing on the detailed documentation of the 10-year strategy, it analyzes the factors that helped and hindered implementation against the World Health Organization (WHO) ExpandNet Framework. The Framework strives to improve the planning and management of the process of scaling-up of successful pilot programs with a focus on sexual and reproductive health, making it particularly suited for an analysis of England's teenage pregnancy strategy. The development and implementation of the strategy matches the Framework's key attributes for successful planning and scaling up of sexual and reproductive health programs. It also matched the attributes identified by the Centre for Global Development for scaled up approaches to complex public health issues. Although the strategy was implemented in a high-income country, analysis against the WHO-ExpandNet Framework identifies many lessons which are transferable to low- and medium-income countries seeking to address high teenage pregnancy rates.

  13. Cost-Effectiveness of Alternative Blood-Screening Strategies for West Nile Virus in the United States.

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available BACKGROUND: West Nile virus (WNV is endemic in the US, varying seasonally and by geographic region. WNV can be transmitted by blood transfusion, and mandatory screening of blood for WNV was recently introduced throughout the US. Guidelines for selecting cost-effective strategies for screening blood for WNV do not exist. METHODS AND FINDINGS: We conducted a cost-effectiveness analysis for screening blood for WNV using a computer-based mathematical model, and using data from prospective studies, retrospective studies, and published literature. For three geographic areas with varying WNV-transmission intensity and length of transmission season, the model was used to estimate lifetime costs, quality-adjusted life expectancy, and incremental cost-effectiveness ratios associated with alternative screening strategies in a target population of blood-transfusion recipients. We compared the status quo (baseline screening using a donor questionnaire to several strategies which differed by nucleic acid testing of either pooled or individual samples, universal versus targeted screening of donations designated for immunocompromised patients, and seasonal versus year-long screening. In low-transmission areas with short WNV seasons, screening by questionnaire alone was the most cost-effective strategy. In areas with high levels of WNV transmission, seasonal screening of individual samples and restricting screening to blood donations designated for immunocompromised recipients was the most cost-effective strategy. Seasonal screening of the entire recipient pool added minimal clinical benefit, with incremental cost-effectiveness ratios exceeding US$1.7 million per quality-adjusted life-year gained. Year-round screening offered no additional benefit compared to seasonal screening in any of the transmission settings. CONCLUSIONS: In areas with high levels of WNV transmission, seasonal screening of individual samples and restricting screening to blood donations

    2015-06-01

    Full Text Available Research on consumer behavior in leisure settings has proposed the relationship among involvement, psychological commitment and loyalty. Nonetheless, very little attention has been given to the conceptualization of the relationship among these constructs in a sport spectator context. The present study examined the relationship among involvement, psychological commitment, and two dimensions of loyalty, namely the attitudinal and behavioral loyalty of sport fans. The participants of this study were 800 soccer fans. The confirmatory factor analysis confirmed the multidimensional factor structure of the involvement scale which was developed for leisure participants by Kyle, Graefe, Manning and Bacon (2003. A structural equation modeling examined the proposed relationship model among involvement, commitment and loyalty. It was found that fans’ involvement affects psychological commitment. Psychological commitment, in turn, influences attitudinal loyalty, and eventually attitudinal loyalty has direct effects on behavioral loyalty. The findings of the study indicate the mechanism through which sport fans become loyal to their team. It is suggested that sport managers should develop involvement, psychological commitment and attitudinal loyalty through marketing strategies in order to maximize sport fans’ behavioral loyalty.

    2012-03-01

    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.

    Service firms have become highly competitive in terms of providing the delivery. The delivery quality in terms of delivery commitments. Delivery commitments impact the customer in deciding for the service. Computing the delivery commitments in stochastic service systems is a real challenge. Delivery commitment forms a key parameter in formulating the service level agreements in B2B markets. In our current work we propose a queuing theoretic approach for computing the delivery commitments. The...

  7. Policy Uncertainty, Investment and Commitment Periods

    2007-07-01

    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.

  8. 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.

    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.

  10. Managing for climate change on federal lands of the western United States: perceived usefulness of climate science, effectiveness of adaptation strategies, and barriers to implementation

    2015-06-01

    Full Text Available Recent mandates in the United States require federal agencies to incorporate climate change science into land management planning efforts. These mandates target possible adaptation and mitigation strategies. However, the degree to which climate change is actively being considered in agency planning and management decisions is largely unknown. We explored the usefulness of climate change science for federal resource managers, focusing on the efficacy of potential adaptation strategies and barriers limiting the use of climate change science in adaptation efforts. Our study was conducted in the northern Rocky Mountains region of the western United States, where we interacted with 77 U.S. Forest Service and Bureau of Land Management personnel through surveys, semistructured interviews, and four collaborative workshops at locations across Idaho and Montana. We used a mixed-methods approach to evaluate managers' perceptions about adapting to and mitigating for climate change. Although resource managers incorporate general language about climate change in regional and landscape-level planning documents, they are currently not planning on-the-ground adaptation or mitigation projects. However, managers felt that their organizations were most likely to adapt to climate change through use of existing management strategies that are already widely implemented for other non climate-related management goals. These existing strategies, (e.g., thinning and prescribed burning are perceived as more feasible than new climate-specific methods (e.g., assisted migration because they already have public and agency support, accomplish multiple goals, and require less anticipation of the future timing and probability of climate change impacts. Participants reported that the most common barriers to using climate change information included a lack of management-relevant climate change science, inconsistent agency guidance, and insufficient time and resources to access

    This paper investigates the determinants of nations' commitment to environmental protection at the international level by focusing on the role of national intelligence and the level of democracy. 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.

    Subjects (N = 98) were randomly assigned to high- and low-responsibility conditions in a commitment-escalation experiment. Global Type A behavior pattern and the underlying dimension of achievement strivings were positively related to the desire to continue the same course of action in the high prior-responsibility condition but not in the low prior-responsibility condition. These findings are discussed in terms of future research into the judgment processes of people with Type A personality and the possible role of escalating commitment in disorders experienced by people with Type A personality.

    2003-07-01

    This paper considers the challenges facing climate change policy makers from different perspectives. In so doing, it reviews some of the decision criteria that might guide policy decisions, as well as practical options on the form that different mitigation commitments might take. Taking a broad, longer-term view of the climate problem provides insights on what criteria might be used to eventually shape decisions about future commitments. The paper draws from previous IEA and OECD papers, from information presented and discussions in previous Annex I Expert Group meetings and from other sources in the open literature.

    2009-07-01

    Full Text Available This article presents a summary of the corporate strategies of the Levi Strauss & Co. firm, a company that has had an important role in each one of the phases of Mexico’s process of integration into the global apparel production: the integration under the shared–production programs, the first stage of NAFTA, and the current stage of decline of Mexican exports and re–positioning of China. The central argument is that, by analyzing the competitive strategies of the leading firms of global apparel networks—as in the case of Levi’s—, we can get closer to the restructuring logic of these networks and understand the changing terms of the international insertion of the countries and firms involved, as in the case of Mexico.

    A preoperative delay in emergency surgery for spontaneous pneumothorax is associated with a poor outcome after surgery and a prolonged hospital stay. To reduce preoperative delays, all tertiary referrals from district general hospitals to our thoracic surgery unit were processed through a 'clinical decisions unit' (CDU). Prior to the establishment of the CDU, these patients were added to a waiting list for a surgical bed. This study has reviewed the effect of this change in admission policy on the efficiency of treatment for non-elective spontaneous pneumothorax. An intergroup comparison (pre-CDU group vs. post-CDU group) was made of the following parameters: referral to transfer time, transfer to surgery time and length of inpatient stay in the referring and tertiary hospitals. There were no significant differences in gender, diagnosis, treatment in the referring hospitals, postoperative clinical outcome, or indications for or type of surgery. The total length of inpatient stay in the referring and tertiary hospitals was significantly reduced for the post-CDU group (12 vs. 15 days; P<0.001), which was attributed to the earlier transfer of patients (18 vs. 78 hours; P<0.001) hours. Allowing surgical access to a traditional medical admission unit is therefore, cost-effective and significantly improves the efficiency of non-elective pneumothorax surgery.

  20. 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.

  1. 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.

    2016-03-01

    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.

    Susan Mary Carr

    2014-04-01

    Full Text Available Objectives: This article reports on the outcomes of two similar projects undertaken during 2011–2012 in Australia (Rural Northern New South Wales and the United Kingdom (Urban Northern United Kingdom that sought to identify the strategies that health professionals employ to actively involve patients with chronic conditions in the planning and delivery of their care. In particular, this study explored understandings and contexts of care that impacted on the participants’ practices. This study was informed by the global shift to partnership approaches in health policy and the growing imperative to deliver patient or client-centred care. Methods: An ethnomethodological design was used, as ethnomethodology does not dictate a set of research methods or procedures, but rather is congruent with any method that seeks to explore what people do in their routine everyday lives. Focus groups and interviews were employed to explore the strategies used by a range of primary health-care providers, such as general practitioners, nurses, social workers, diabetes educators, dieticians and occupational therapists, to support clients to effectively manage their own chronic conditions. Results: Data from both studies were synthesised and analysed thematically, with the themes reflecting the context, similarities and differences of the two studies that the participants felt had either facilitated or blocked their efforts to support their clients to adopt self-care strategies. Conclusion: Supporting patients/clients to engage in actively self-managing their health-care needs requires changes to clients’ and clinicians’ traditional perspectives on their roles. The barriers and enablers to supporting clients to manage their own health needs were similar across both locations and included tensions in role identity and functions, the discourse of health-care professionals as ‘experts’ who deliver care and their level of confidence in being facilitators who

    2014-12-01

    Teamwork is essential for ensuring the quality and safety of health care delivery in the intensive care unit (ICU). This article addresses what we know about teamwork, team tasks, and team improvement strategies in the ICU to identify the strengths and limitations of the existing knowledge base to guide future research. A keyword search of the PubMed database was conducted in February 2013. Keyword combinations focused on 3 areas: (1) teamwork, (2) the ICU, and (3) training/quality improvement interventions. All studies that investigated teamwork, team tasks, or team interventions within the ICU (ie, intradepartment) were selected for inclusion. Teamwork has been investigated across an array of research contexts and task types. The terminology used to describe team factors varied considerably across studies. The most common team tasks involved strategy and goal formulation. Team training and structured protocols were the most widely implemented quality improvement strategies. Team research is burgeoning in the ICU, yet low-hanging fruit remains that can further advance the science of teams in the ICU if addressed. Constructs must be defined, and theoretical frameworks should be referenced. The functional characteristics of tasks should also be reported to help determine the extent to which study results might generalize to other contexts of work. Copyright © 2014 Elsevier Inc.

    2014-01-01

    Background The World Health Organization (WHO) launched a multimodal strategy and campaign in 2009 to improve hand hygiene practices worldwide. Our objective was to evaluate the implementation of the strategy in United States health care facilities. Methods From July through December 2011, US facilities participating in the WHO global campaign were invited to complete the Hand Hygiene Self-Assessment Framework online, a validated tool based on the WHO multimodal strategy. Results Of 2,238 invited facilities, 168 participated in the survey (7.5%). A detailed analysis of 129, mainly nonteaching public facilities (80.6%), showed that most had an advanced or intermediate level of hand hygiene implementation progress (48.9% and 45.0%, respectively). The total Hand Hygiene Self-Assessment Framework score was 36 points higher for facilities with staffing levels of infection preventionists > 0.75/100 beds than for those with lower ratios (P = .01) and 41 points higher for facilities participating in hand hygiene campaigns (P = .002). Conclusion Despite the low response rate, the survey results are unique and allow interesting reflections. Whereas the level of progress of most participating facilities was encouraging, this may reflect reporting bias, ie, better hospitals more likely to report. However, even in respondents, further improvement can be achieved, in particular by embedding hand hygiene in a stronger institutional safety climate and optimizing staffing levels dedicated to infection prevention. These results should encourage the launch of a coordinated national campaign and higher participation in the WHO global campaign. PMID:24581011

    Full Text Available This research study examines the relationship between transformational, transactional and passive/avoidant leadership styles and three dimensions of organizational commitment – affective, continuance, and normative in two subsidiaries of one multinational organization. The research findings revealed that transformational leadership has the strongest impact on affective commitment, although transactional leadership also affects affective commitment. Transformational leadership also has a significant positive affect on normative commitment. Transactional leadership has a significant positive affect on continuance commitment and positive/avoidant leadership has a significant negative affect on affective commitment.

    We consider non-malleable (NM) and universally composable (UC) commitment schemes in the common reference string (CRS) model. We show how to construct non-interactive NM commitments that remain non-malleable even if the adversary has access to an arbitrary number of commitments from honest players...... version based on the strong RSA assumption. For UC commitments, we show that existence of a UC commitment scheme in the CRS model (interactive or not) implies key exchange and - for a uniform reference string - even implies oblivious transfer. This indicates that UC commitment is a strictly stronger...

    Nurses (N = 179; Study 1) and managers (N = 154; Study 2) participated in 2 panel studies examining the relationship among prior commitment (affective and continuance commitment and perceived organizational support), coping strategies, and survivors' attitudes and perceptions during and following downsizing. In Study 1, perceived organizational support was significantly positively related to control-oriented coping, job satisfaction, and intention to remain and negatively related to perceived job insecurity and burnout 2 years later. In Study 2, coping mediated the relationship between the prior commitment variables and job alienation, health symptoms, and burnout following the downsizing. Control-oriented coping was associated with elevated levels of health symptoms and burnout following the downsizing, suggesting that control-oriented coping may have positive effects in the short term but potentially harmful effects in the long term.

    This paper studies the impacts of physical contracts and financial contracts on the bidding strategies of GENCOs, including Physical Bilateral Contracts, Contracts for Difference (CfDs), Call Options and Put Options under discriminatory pricing mechanism. The integrated bidding decision model is applied, which has three main modules - probabilistic local marginal price simulator, market-oriented unit commitment model and multi-criteria decision system. The numerical results show that the GENCO will choose different bidding strategies if it holds different types of contract. The results also suggest that CfDs have the best performance for risk alleviation. (author)

    Manufacturing firms in capital-intensive industries face inherent demand volatility for their products and the inability to change their capacity quickly. To cope with these challenges, manufacturers often enter into contracts with their customers that offer greater certainty of supply in return for more predictable orders. In this paper, we study a "forecast-commitment" contract in which the customer provides a forecast, the supplier makes a production commitment to the customer based on the...

    It was shown that an increase in the bacteriochlorophyll (BChl) c antenna size observed upon lowering growth light intensities led to enhancement of the hyperchromism of the BChl c Q(y) absorption band of the green photosynthetic bacterium Chloroflexus aurantiacus. With femtosecond difference absorption spectroscopy, it was shown that the amplitude of bleaching of the oligomeric BChl c Q(y) band (as compared to that for monomeric BChl a) increased with increasing BChl c content in chlorosomes. This BChl c bleaching amplitude was about doubled as the chlorosomal antenna size was about trebled. Both sets of findings clearly show that a unit BChl c aggregate in the chlorosomal antenna is variable in size and governed by the grow light intensity, thus ensuring the high efficiency of energy transfer within the BChl c antenna regardless of its size.

    The incidence of interracial and interethnic dating and marriage in the United States has increased. This investigation examined dating and commitment choices as a function of ethnicity and sex among groups of Euro-American, Hispanic-American, Asian-American, and African-American college students. A convenience sample of college students comprising 329 heterosexual subjects (134 men, 195 women) was surveyed regarding their partner preferences for dating, visiting parents, marriage, and bearing children. It was hypothesized that subjects would consider dating partners from different ethnic groups, but when making a commitment to marriage and children would prefer members of their own group. This hypothesis was supported in half of the groups: Euro-American men, African-American men, Asian-American women, and African-American women. A discussion of dating and commitment choices among ethnic and sex groups is presented and discussed.

    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.

    Full Text Available Orientation: Employees’ perceptions of rewards are related to their affective commitment and intrinsic motivation, which have been associated with staff turnover.Research purpose: The study sought to establish the relationship between intrinsic and different extrinsic rewards with intrinsic motivation and affective commitment.Motivation for the study: South African organisations are grappling with employee retention. Literature shows that employees who are more motivated and committed to their organisation are less likely to quit. Rewards management strategies serve to create a motivated and committed workforce. Using the correct types of rewards can thus provide a competitive advantage.Research design, approach and method: A cross-sectional, correlational study was conducted. Questionnaire data of 399 South African employees were analysed using bivariate correlations and multiple regression.Main findings: Three main findings emerged. Firstly, there is a relationship between all types of rewards investigated and the two outcome variables. Secondly, this relationship is stronger for intrinsic than for extrinsic rewards and thirdly, monetary rewards do not account for the variance in intrinsic motivation above that of non-monetary rewards.Practical/managerial implications: Rewards management strategies should focus on job characteristics and designs to increase staff intrinsic rewards and include non-monetary rewards, such as supportive leadership, to encourage employees’ intrinsic motivation and affective commitment.Contribution/value-add: This research demonstrated the important role different rewards, particularly intrinsic non-monetary rewards, play in creating a committed and motivated workforce. The insights gained from this study can promote organisational effectiveness. Suggestions of how to expand on and refine the current study are addressed.

    To develop or enhance the job satisfaction and organisational commitment of nurses by implementing job rotation and internal marketing practices. No studies in the nursing management literature have addressed the integrated relationships among job rotation, internal marketing, job satisfaction and organisational commitment. This cross-sectional study included 266 registered nurses (response rate 81.8%) in two southern Taiwan hospitals. Software used for data analysis were SPSS 14.0 and AMOS 14.0 (structural equation modelling). Job rotation and internal marketing positively affect the job satisfaction and organisational commitment of nurses, and their job satisfaction positively affects their organisational commitment. Job rotation and internal marketing are effective strategies for improving nursing workforce utilisation in health-care organisations because they help to achieve the ultimate goals of increasing the job satisfaction of nurses and encouraging them to continue working in the field. This in turn limits the vicious cycle of high turnover and low morale in organisations, which wastes valuable human resources. Job rotation and internal marketing help nursing personnel acquire knowledge, skills and insights while simultaneously improving their job satisfaction and organisational commitment. © 2013 John Wiley & Sons Ltd.

  20. The roles of parties with different commitments under the Kyoto Protocol and implications for NAFTA

    A government perspective on climate change negotiations was presented with particular reference to Canada's cleaner energy exports, the Kyoto mechanism and the second commitment period. The author emphasized the importance of cleaner energy exports for Canada, although progress is likely to be slow in this area because of the opposition among other Parties. Whatever approach the United States takes to trading, it must be compatible with the Kyoto Protocol. Eligibility for trading in North America was discussed with reference to what effect Canada's ratification of the Protocol would have on energy exports. It was noted that if Canada ratifies, it could be both a buyer and a seller, whereas the United States could only buy and Mexico could only sell. The author also suggested that developing countries or major emitters should take on commitments in order to provide greater compatibility in the North American context, especially if the United States rejoined the Kyoto Protocol.
