Persistence of airline accidents.

2010-10-01

This paper expands on air travel accident research by examining the relationship between air travel accidents and airline traffic or volume in the period from 1927-2006. The theoretical model is based on a representative airline company that aims to maximise its profits, and it utilises a fractional integration approach in order to determine whether there is a persistent pattern over time with respect to air accidents and air traffic. Furthermore, the paper analyses how airline accidents are related to traffic using a fractional cointegration approach. It finds that airline accidents are persistent and that a (non-stationary) fractional cointegration relationship exists between total airline accidents and airline passengers, airline miles and airline revenues, with shocks that affect the long-run equilibrium disappearing in the very long term. Moreover, this relation is negative, which might be due to the fact that air travel is becoming safer and there is greater competition in the airline industry. Policy implications are derived for countering accident events, based on competition and regulation. © 2010 The Author(s). Journal compilation © Overseas Development Institute, 2010.

2011-10-01

This study investigates drivers of airline loyalty. It contributes to the body of knowledge in the area by investigating loyalty for a number of a priori market segments identified by airline management and by using a method which accounts for the multi-step nature of the airline choice process. The study is based on responses from 687 passengers. Results indicate that, at aggregate level, frequent flyer membership, price, the status of being a national carrier and the reputation of the airline as perceived by friends are the variables which best discriminate between travellers loyal to the airline and those who are not. Differences in drivers of airline loyalty for a number of segments were identified. For example, loyalty programs play a key role for business travellers whereas airline loyalty of leisure travellers is difficult to trace back to single factors. For none of the calculated models satisfaction emerged as a key driver of airline loyalty.

Airline Crew Training

Science.gov (United States)

1989-01-01

The discovery that human error has caused many more airline crashes than mechanical malfunctions led to an increased emphasis on teamwork and coordination in airline flight training programs. Human factors research at Ames Research Center has produced two crew training programs directed toward more effective operations. Cockpit Resource Management (CRM) defines areas like decision making, workload distribution, communication skills, etc. as essential in addressing human error problems. In 1979, a workshop led to the implementation of the CRM program by United Airlines, and later other airlines. In Line Oriented Flight Training (LOFT), crews fly missions in realistic simulators while instructors induce emergency situations requiring crew coordination. This is followed by a self critique. Ames Research Center continues its involvement with these programs.

Receipt and use of half-fare airline coupons at selected Department of Energy field locations

Energy Technology Data Exchange (ETDEWEB)

1980-08-11

The receipt and use of half-fare coupons obtained by employees of DOE field offices and DOE contractors while traveling at DOE expense were reviewed. These coupons, issued by United Airlines and American Airlines, provided for air travel at half-fare if used before December 15, 1979. Potential savings to DOE through coupon use ranging from $50,000 to $100,000 were lost, because of ineffective management action by both federal and contractor officials. Recommendations were that DOE ascertain the extent of the failure of contractors to recover coupons from their employees and recover from the contractors the amounts lost. IG submitted a draft of this final report for comment and received the comments of the Controller, the Director of Administration, and the Director of Procurement and Contracts Management. The comments included useful information; and where appropriate, the final report was changed to reflect the comments. In addition, the comments in their entirety are contained in the appendices.

Perceptions of Service Quality: An Empirical Assessment of Modified SERVQUAL Model among Domestic Airline Carriers in Nigeria

Directory of Open Access Journals (Sweden)

Ganiyu Rahim A.

2016-12-01

Full Text Available Literature is replete with a large number of theories related to service quality measurement and dimensions in an airline context. To date, there is no consensus of opinion on the generic model and of the number of dimensions most appropriate to evaluate service quality in airline industry. This study investigates service quality dimensions in the Nigerian airline industry. The cross-sectional survey research design was adopted. Convenience sampling was used to select 800 respondents among departing air travellers in Lagos State. A structured questionnaire containing 28 items was developed to evaluate the perceived service quality of domestic airlines. The data collected were analysed using descriptive statistics, Pearson’s correlation analysis, and one-sample t-test. The dimensionality of perceived service quality in Nigeria’s airline industry was explored using exploratory factor analysis. From the analysis carried out, it was established that the modified SERVQUAL model provided a satisfactory level of overall reliability in Nigeria’s airline context, which implies that all the items were cohesive in forming the SERVQUAL dimensions. According to the findings of this study, all service quality dimensions are positively and significantly interrelated. The perceived service quality of domestic airlines across these dimensions was found to be poor. The most dissatisfied dimensions in order of ranking were: flight pattern, reliability, facilities, assurance, responsiveness, employee, and customization. On the basis of the aforementioned findings, this study concludes that airline operators should redefine their service standards to one that is customer-focused by identifying the dimension of service quality most preferred by the passengers and continuously strive to improve service delivery. The study recommends that airline operators should recognize the changing needs and expectations of air travellers and customize their range of services

1976-01-01

Several mathematical models now exist which determine the operating economics for a United States trunk airline. These models are valuable in assessing the impact of new aircraft into an airline's fleet. The use of a trunk airline cost model for the local service airline does not result in representative operating costs. A new model is presented which is representative of the operating conditions and resultant costs for the local service airline. The calculated annual direct and indirect operating costs for two multiequipment airlines are compared with their actual operating experience.

Airlines shape their route network by defining their routes through supply and demand considerations, paying little attention to network performance indicators, such as network robustness. However, the collapse of an airline network can produce high financial costs for the airline and all its geographical area of influence. The aim of this study is to analyze the topology and robustness of the network route of airlines following Low Cost Carriers (LCCs) and Full Service Carriers (FSCs) business models. Results show that FSC hubs are more central than LCC bases in their route network. As a result, LCC route networks are more robust than FSC networks.

Justice Department Airline Merger Policy

Farmer, D. A.

1972-01-01

Justice Department airline merger policy is developed within the context of the Federal Aviation Act, in which there is an unusually explicit reliance on competition as a means of fulfilling statutory goals. The economics of the airline industry appear to indicate that low concentration and vigorous competition are particularly viable and desirable. Several factors, including existing regulatory policy, create incentives for airlines to merge whether or not an individual merger promotes or conflicts with the public interest. Specific benefits to the public should be identified and shown to clearly outweight the detriments, including adverse competitive impact, in order for airline mergers to be approved.

Airline Deregulation and Public Policy

Science.gov (United States)

Morrison, Steven A.; Winston, Clifford

1989-08-01

An assessment of the effects of airline deregulation on travelers and carriers indicates that deregulation has provided travelers and carriers with 14.9 billion of annual benefits (1988 dollars). Airport congestion, airline safety, airline bankruptcy, and mergers are also analyzed and found in most cases to have reduced benefits. But, these costs should not be attributed to deregulation per se, but to failures by the government to pursue appropriate policies in these areas. Pursuit of policies that promote airline competition and efficient use of airport capacity would significantly increase the benefits from deregulation and would provide valuable guidance for other industries undergoing the transition to deregulation.

Full Text Available This paper contributes to the knowledge on corporate social responsibility (CSR initiatives of by businesses and its ability to influence their financial performance. Consequently, the main objective is to examine the relationship between CSR and financial performance in the airline industry in Central and Eastern Europe. The paper does not attempt to establish causality between CŚR and financial performance. The paper attempts to contribute to the existing knowledge in the field by examining the extent to which CSR relates to financial performance of airline firms. A sample of 20 audited financial statements of airline firms were selected randomly. The study analyzed the impact of CSR activities on the financial performance of firms. The Return on Equity (ROE and Return on Assets (ROA were used as indicators to measure financial performance of firms whiles the independent variables were Community Performance (CP, Environment Management System (EMS and Employee Relations (ER. The study found that there is a significant positive relationship between CSR initiatives and financial performance measures. More specifically, there was found to be a positive relationship between the independent variables of CSR thus, CP, EMS and ER and the financial performance of airline firms in terms of the ROE and ROA.

2014-01-01

Full Text Available Airline's network is the key element of its business strategy and selected network structure will not have influence only on the airline's costs but could gain some advantage in revenues, too. Network designing implies that an airline has to make decisions about markets that it will serve and how to serve those markets. Network choice raises the following questions for an airline: a what markets to serve, b how to serve selected markets, c what level of service to offer, d what are the benefits/cost of the that decisions and e what is the influence of the competition. We analyzed the existing airline business models and corresponding network structure. The paper highlights the relationship between the network structures and the airline business strategies. Using a simple model we examine the relationship between the network structure and service quality in deregulated market.

Full Text Available Sustainable development has always been the objective of many fields, including the tourism and transportation sector. However, a major part of this sector, the airline industry, deals with many negative impacts, such as air pollution, noise, CO2 emission, and labor practice. Corporate social responsibility (CSR is a strategic business activity that can enhance the sustainability of the airline industry. The results of the Dow Jones Sustainability Indices (DJSI reveal that airlines of Western countries exhibit a more remarkable CSR performance than Asia-Pacific airlines, suggesting that the CSR programs of Asia-Pacific airlines need improvement. By constructing an evaluation hierarchy and applying the decision-making trial and evaluation laboratory (DEMATEL method, this study found that the key strategic factors in the airline industry’s implementation of CSR include corporate governance, risk and crisis management, brand management, and product responsibility (safety.

Environmental charges in airline markets

Carlsson, Fredrik [Goeteborg Univ., Dept. of Economics, Goeteborg (Sweden)

2002-07-01

Over the last two decades many airline markets have been deregulated, resulting in increased competition and use of different types of networks. At the same time there has been an intense discussion on environmental taxation of airline traffic. It is likely that an optimal environmental charge and the effects of a charge differ between different types of aviation markets. In this paper, we derive optimal flight (environmental) charges for different types of airline markets. The first type of market is a multiproduct monopoly airline operating either a point-to-point network or a hub-and-spoke network. The optimal charge is shown to be similar in construction to an optimal charge for a monopolist. We also compare the environmental impact of the two types of networks. Given no differences in marginal damages between airports we find that an airline will always choose the network with the highest environmental damages. The second type of market we investigate is a multiproduct duopoly, where two airlines compete in both passengers and flights. The formulation of the optimal charge is similar to the optimal charge of a single product oligopoly. However, we also show that it is, because of strategic effects, difficult to determine the effects of the charge on the number of flights. (Author)

Concurrent airline fleet allocation and aircraft design with profit modeling for multiple airlines

Science.gov (United States)

Govindaraju, Parithi

A "System of Systems" (SoS) approach is particularly beneficial in analyzing complex large scale systems comprised of numerous independent systems -- each capable of independent operations in their own right -- that when brought in conjunction offer capabilities and performance beyond the constituents of the individual systems. The variable resource allocation problem is a type of SoS problem, which includes the allocation of "yet-to-be-designed" systems in addition to existing resources and systems. The methodology presented here expands upon earlier work that demonstrated a decomposition approach that sought to simultaneously design a new aircraft and allocate this new aircraft along with existing aircraft in an effort to meet passenger demand at minimum fleet level operating cost for a single airline. The result of this describes important characteristics of the new aircraft. The ticket price model developed and implemented here enables analysis of the system using profit maximization studies instead of cost minimization. A multiobjective problem formulation has been implemented to determine characteristics of a new aircraft that maximizes the profit of multiple airlines to recognize the fact that aircraft manufacturers sell their aircraft to multiple customers and seldom design aircraft customized to a single airline's operations. The route network characteristics of two simple airlines serve as the example problem for the initial studies. The resulting problem formulation is a mixed-integer nonlinear programming problem, which is typically difficult to solve. A sequential decomposition strategy is applied as a solution methodology by segregating the allocation (integer programming) and aircraft design (non-linear programming) subspaces. After solving a simple problem considering two airlines, the decomposition approach is then applied to two larger airline route networks representing actual airline operations in the year 2005. The decomposition strategy serves

Dietary Advice for Airline Travel.

Science.gov (United States)

Leggat; Nowak

1997-03-01

In addition to their regular meal service, most of the major domestic and international airlines offer special meals. It should be noted that regular meal services on international flights often give a choice of meals, even in economy class, and often include a salad and or fruit dish, which could be consumed by most people. More airlines also seem to be moving towards having at least one more culturally appropriate meal on the menu, particularly for relevant flight sectors. However, these meals may be inappropriate for some passengers, and there is a need for this special meals service. Meals services on airlines have improved greatly in recent years, particularly with the employment of consultant dietitians to the catering staff of airlines and advances in chef training. Special meal services are designed to cater to the most common variations of meals required by most passengers for medical, religious, or other reasons. The special requirements for these meals are described elsewhere.1 It is important to realize that the meals are designed and the ingredients interpreted by that airline, and may not necessarily reflect what the traveler might eat at home. So it is important to advise travelers not to have high expectations of this special meal service. This paper aims to provide some basic practical advice for selection of special diets for airline travelers.

Full Text Available Russian Federation is entering a new system of Occupational standards as norm of competence that people are ex- pected to achieve in their work, and the knowledge and skills they need to apply effectively. There may be conflicts in pro- fessional co-operation between the new system of Occupational standards and the old system of Managers, specialists and workforce qualification reference books. It may affect the common area of occupational environmental hazards. Employ- ees, who passed compulsory medical examination, can have poor health conditions. It affects the inability of the employees to perform their aircraft maintenance duties. It may be a particular occupational environment factor. A five-point scale of possible damage severity was proposed for this factor. It is known that a sick employee's duties are redistributed among the remaining employees. Redistributing of a sick employee's duties increases the task load of the remaining ones in terms of overtime work for instance. It, ultimately, may compromise normal operation of employees. The results can be used when taking management decisions in process organization of airlines, as well as in other industries.

Managing airlines: the cost of complexity

Energy Technology Data Exchange (ETDEWEB)

Trapote-Barreira, C.; Deutschmann, A.; Robuste, F.

2016-07-01

This paper is dedicated to the structure of airline networks as a sink of efficient airline operations. Parameters of complexity were derived and mirrored on level of service as well as efficiency parameters. Airlines usually considerers an operational overhead to predict the total flight operation cost. This parameter includes the expected cost for disruptions and delays. When an airline has to mobilize an aircraft in a base for recovering the service or for breaking an emergent dynamic, then it is running extra costs. The cost of managing complexity in the airline industry has a direct impact on profit and loss account. Therefore, this paper presents an integrated approach to evaluate this cost, based on padding and aircrafts dedicated to recover disruptions. Finally, some additional indicators are derived to evaluate reliability improvement as part of complex performance. (Author)

We investigate the impacts of including aviation into European Union Emission Trading Scheme on airline efficiency since 2008. Airline efficiency is divided into three stages: Operations Stage, Services Stage and Sales Stage, and Greenhouse Gases Emission is treated as an undesirable output of Services Stage. Two models, Network Slacks-Based Measure with weak disposability and Network Slacks-Based Measure with strong disposability, are established to evaluate the efficiencies of 22 international airlines from 2008 to 2012. The results show that: (1) Most airlines' efficiencies have increased in the period. (2) The average efficiency of European airlines is much higher than that of non-European airlines. (3) The model with weak disposability is more reasonable in distinguishing the airline efficiency while strong disposability is a more reasonable way in treating undesirable outputs. - Highlights: • A new theoretical model of airlines efficiency is built. • Network Slacks-Based Measure models with weak disposability and strong disposability are proposed. • The efficiencies of 22 airlines from 2008 to 2012 are evaluated. • The impacts of including airlines into European Union Emission Trading Scheme are analyzed.

OBJECTIVE To analyze lifestyle risk factors related to direct healthcare costs and the indirect costs due to sick leave among workers of an airline company in Brazil. METHODS In this longitudinal 12-month study of 2,201 employees of a Brazilian airline company, the costs of sick leave and healthcare were the primary outcomes of interest. Information on the independent variables, such as gender, age, educational level, type of work, stress, and lifestyle-related factors (body mass index, physical activity, and smoking), was collected using a questionnaire on enrolment in the study. Data on sick leave days were available from the company register, and data on healthcare costs were obtained from insurance records. Multivariate linear regression analysis was used to investigate the association between direct and indirect healthcare costs with sociodemographic, work, and lifestyle-related factors. RESULTS Over the 12-month study period, the average direct healthcare expenditure per worker was US$505.00 and the average indirect cost because of sick leave was US$249.00 per worker. Direct costs were more than twice the indirect costs and both were higher in women. Body mass index was a determinant of direct costs and smoking was a determinant of indirect costs. CONCLUSIONS Obesity and smoking among workers in a Brazilian airline company were associated with increased health costs. Therefore, promoting a healthy diet, physical activity, and anti-tobacco campaigns are important targets for health promotion in this study population. PMID:26039398

Data on sick leave days were available from the company register, and data on healthcare costs were obtained from insurance records. Multivariate linear regression analysis was used to investigate the association between direct and indirect healthcare costs with sociodemographic, work, and lifestyle-related factors. RESULTS Over the 12-month study period, the average direct healthcare expenditure per worker was US$505.00 and the average indirect cost because of sick leave was US$249.00 per worker. Direct costs were more than twice the indirect costs and both were higher in women. Body mass index was a determinant of direct costs and smoking was a determinant of indirect costs. CONCLUSIONS Obesity and smoking among workers in a Brazilian airline company were associated with increased health costs. Therefore, promoting a healthy diet, physical activity, and anti-tobacco campaigns are important targets for health promotion in this study population.

Airline Applications of Business Intelligence Systems

Directory of Open Access Journals (Sweden)

Mihai ANDRONIE

2015-09-01

Full Text Available Airline industry is characterized by large quantities of complex, unstructured and rapid changing data that can be categorized as big data, requiring specialized analysis tools to explore it with the purpose of obtaining useful knowledge as decision support for companies that need to fundament their activities and improve the processes they are carrying on. In this context, business intelligence tools are valuable instruments that can optimally process airline related data so that the activities that are conducted can be optimized to maximize profits, while meeting customer requirements. An airline company that has access to large volumes of data (stored into conventional or big data repositories has two options to extract useful decision support information: processing data by using general-purpose business intelligence systems or processing data by using industry specific business intelligence systems. Each of these two options has both advantages and disadvantages for the airline companies that intend to use them. The present paper presents a comparative study of a number of general-purpose and airline industry specific business intelligence systems, together with their main advantages and disadvantages.

Full Text Available The business models innovation in airlines can contribute to the creation of value, competitive advantage and profitability with new possibilities of action. The proposed paper aimed to identify the business models adopted by airlines and identify how the innovation occurs at these organizations. The methodology adopted is characterized as empirical, exploratory and descriptive research by multiple case study with three major Brazilian airlines. The results demonstrate that the search for paradigm breaks, related to the dichotomic traditional models of low-cost and full-service, toward hybrid business models occur linearly, as examples highlighted by companies, in which internal changes in business models are considered major organizational innovations.

An Economic Model of U.S. Airline Operating Expenses

Science.gov (United States)

Harris, Franklin D.

2005-01-01

This report presents a new economic model of operating expenses for 67 airlines. The model is based on data that the airlines reported to the United States Department of Transportation in 1999. The model incorporates expense-estimating equations that capture direct and indirect expenses of both passenger and cargo airlines. The variables and business factors included in the equations are detailed enough to calculate expenses at the flight equipment reporting level. Total operating expenses for a given airline are then obtained by summation over all aircraft operated by the airline. The model's accuracy is demonstrated by correlation with the DOT Form 41 data from which it was derived. Passenger airlines are more accurately modeled than cargo airlines. An appendix presents a concise summary of the expense estimating equations with explanatory notes. The equations include many operational and aircraft variables, which accommodate any changes that airline and aircraft manufacturers might make to lower expenses in the future. In 1999, total operating expenses of the 67 airlines included in this study amounted to slightly over $100.5 billion. The economic model reported herein estimates $109.3 billion.

Assessing the Relationship between Airlines' Maintenance Outsourcing and Aviation Professionals' Job Satisfaction

Science.gov (United States)

McCamey, Rotorua

The current economic and security challenges placed an additional burden on U.S. airlines to provide optimum service at reasonable costs to the flying public. In efforts to stay competitive, U.S. airlines increased foreign-based outsourcing of aircraft major repair and overhaul (MRO) mainly to reduce labor costs and conserve capital. This concentrated focus on outsourcing and restructuring, ignored job dissatisfaction among remaining employees which could reduce and or eliminate an airline's competitiveness. The purpose of this quantitative study was (a) to assess the relationship between increased levels of foreign-based MRO outsourcing and aviation professionals' job satisfaction (Y1); (b) to assess the influence of increased levels of foreign-based outsourcing on MRO control (Y2), MRO error rate (Y3), and MRO technical punctuality (Y4) as perceived by aviation professionals; and (c) to assess the influence of increased levels of foreign-based MRO outsourcing on technical skills (Y5) and morale ( Y6) as perceived by aviation professionals. The survey instrument was utilized based on Paul Spector's Job Satisfaction Questionnaire and MRO specific questions. A random sample of 300 U.S. airline participants was requested via MarketTools to meet required sample size of 110 as determined through a priori power analysis. Study data rendered 198 useable surveys of 213 total responses, and correlation, multiple regression, and ANOVA methods were used to test study hypotheses. The Spearman's rho for (Y 1) was statistically significant, p = .010 and multiple regression was statistically significant, p < .001. A one-way ANOVA indicated participants differed in their opinions of (Y2) through (Y6), Recommendations for future research include contrasting domestic and global MRO providers, and examining global aircraft parts suppliers and aviation technical training.

Discretionary salt use in airline meal service.

Wallace, S; Wellman, N S; Dierkes, K E; Johnson, P M

1987-02-01

Salt use in airline meal service was studied through observation of returned meal trays of 932 passengers. Observation and weighing of salt packets on returned trays revealed that 64% of passengers did not salt their airline dinner, while 6% used the entire salt packet, 0.92 gm NaCl (362 mg Na). Average discretionary salt use among the 234 passengers (25%) who added salt was 0.57 gm NaCl (232 mg Na). Estimates of total sodium in the four airline dinners averaged 2.0 gm NaCl (786 mg Na). Laboratory assays of menu items produced by the airline foodservice differed 3% to 19% from estimated values. Sodium content of the four airline dinner menus was similar and did not affect salt use. Discretionary salt use was related to the total amount of entrée consumed but was not affected by the amount of salad consumed. It is postulated that salt use in the "captive" airline situation is predicated on consistent, habitual practices. Lowering sodium consumption in this setting may require alteration in both food preparation methods and quantity of salt presented in the packets.

Rhoades, Dawna L.; Waguespack, Blaise, Jr.

2000-01-01

This study examined the service quality of 25 U.S. airlines (1987-1996) using data from the Department of Transportation's Air Travel Consumer Report. After a total quality and total complaint rate was calculated for these airlines, a 95 percent confidence interval was placed around the yearly and company means calculated to examine those cases that were significantly different from the mean. Results indicate that while the major carriers are converging toward a higher level of quality, there continues to be significant yearly variation. The service quality of regional carriers was much lower than major carriers and showed much greater variation.

How to Control Airline Routes from the Supply Side: The Case of TAP

Science.gov (United States)

Button, Kenneth; Costa, Alvaro; Reis, Vasco

2005-01-01

Competition in the European airline industry is currently fierce in the face of depressed demand conditions, and in the wake of privatizations and liberalization. The Portuguese flag carrier, TAP Air Portugal, operates within this environment. It is a medium sized carrier that was part of the defunct Qualiflyer Group alliance and has recently joined the Star Alliance. It controls more than 50% of the air market between Europe and Brazil and Europe and Angola. Nevertheless, it has been experiencing financial losses. One reason for this is that, following the reasoning of Ronald Coase (1946), it is difficult for any company with decreasing average costs to recover full costs in a highly competitive market. One way of approaching the problem is to establish quasi-monopoly power and airlines have done this through such things as frequent flyer programs and hub-and-spoke operations. Other airlines, notably charter carriers, have sought to adjust capacity and services to meet an anticipated cash flow. In practice, many have used a combination of measures with mixed success. This paper focuses on how TAP has responded to changing conditions by adjusting its supply-side activities in terms of restructuring its network to maximize potential revenues.

Thibeault, Claude; Evans, Anthony D

2015-07-01

Medical Guidelines for Airline Travel provide information that enables healthcare providers to properly advise patients who plan to travel by air. Treating physicians should advise patients in need of special services to contact the airline well before travel to find out if the required services will be available. Ensuring the required services are available throughout a journey can be challenging, especially when different airlines and aircraft types are involved. For example, airlines carry a limited supply of oxygen for use in the event of an unexpected in-flight emergency; however, this supply is not intended for use by passengers needing supplemental oxygen. Arrangements must be made in advance with the airline. Therefore, early contact with the airline is helpful.

Assessing flight safety differences between the United States regional and major airlines

Science.gov (United States)

Sharp, Broderick H.

During 2008, the U.S. domestic airline departures exceeded 28,000 flights per day. Thirty-nine or less than 0.2 of 1% of these flights resulted in operational incidents or accidents. However, even a low percentage of airline accidents and incidents continue to cause human suffering and property loss. The charge of this study was the comparison of U.S. major and regional airline safety histories. The study spans safety events from January 1982 through December 2008. In this quantitative analysis, domestic major and regional airlines were statistically tested for their flight safety differences. Four major airlines and thirty-seven regional airlines qualified for the safety study which compared the airline groups' fatal accidents, incidents, non-fatal accidents, pilot errors, and the remaining six safety event probable cause types. The six other probable cause types are mechanical failure, weather, air traffic control, maintenance, other, and unknown causes. The National Transportation Safety Board investigated each airline safety event, and assigned a probable cause to each event. A sample of 500 events was randomly selected from the 1,391 airlines' accident and incident population. The airline groups' safety event probabilities were estimated using the least squares linear regression. A probability significance level of 5% was chosen to conclude the appropriate research question hypothesis. The airline fatal accidents and incidents probability levels were 1.2% and 0.05% respectively. These two research questions did not reach the 5% significance level threshold. Therefore, the airline groups' fatal accidents and non-destructive incidents probabilities favored the airline groups' safety differences hypothesis. The linear progression estimates for the remaining three research questions were 71.5% for non-fatal accidents, 21.8% for the pilot errors, and 7.4% significance level for the six probable causes. These research questions' linear regressions are greater than

Full Text Available By applying the game theory, the relationship between airline ticket price and optimal flight frequency is analyzed. The paper establishes the payoff matrix of the flight frequency in noncooperation scenario and flight frequency optimization model in cooperation scenario. The airline alliance profit distribution is converted into profit distribution game based on the cooperation game theory. The profit distribution game is proved to be convex, and there exists an optimal distribution strategy. The results show that joining the airline alliance can increase airline whole profit, the change of negotiated prices and cost is beneficial to profit distribution of large airlines, and the distribution result is in accordance with aviation development.

Full Text Available Despite growing literature on the different aspects of airline service quality in relation to behavioural intentions, less attention has been paid to some specific aspects of in-flight services. The focus of the present research is, therefore, on a multiple conceptual model of the quality of in-flight services in relation to passengers’ perception of value, followed by recommendations (word of mouth - WOM of airlines, as well as the quality and comfort of airline seats. The study is performed using two databases of reviewers’/passengers’ opinions regarding the quality of in-flight airline services and airline seat comfort. Our research results reveal that the perceived comfort of the airplane seat is the most important factor of passengers’ perceived quality of in-flight airline services, which also considerably affects the passengers’ perception of value, and consequently moderates behavioural intentions (in our research, expressed through positive WOM. The analysis of the relative importance of the components of perceived airline seats’ comfort shows that seat width is the most significant factor that contributes to the overall perceived comfort of the airline seat.

Hybrid” airlines – Generating value between low-cost and traditional

Directory of Open Access Journals (Sweden)

Stoenescu Cristina

2017-07-01

Full Text Available Over the last years, the rise of low-cost airlines has determined significant changes in the airline industry and has shaped the evolution of the existing business models. Low-cost airlines started by offering basic services at very low prices; traditional airlines responded by equally cutting costs and reinventing the services offered, with an orientation towards braking down the fare and implementing add-ons, in order to become cost-efficient. As traditional airlines developed strategies to become competitive in this new environment, low-cost airlines started focusing on new ways of enhancing passenger experience and attracting new market segments. As a result, the fragmentation of the market segments addressed by low cost carriers and traditional airlines became less obvious and the characteristics of both business models started to blend at all levels (airline operation, distribution channels, loyalty programs, fleet selection. Thus, this new competition became the foundation of the development of a new „hybrid” carrier, between the low-cost and the traditional models. This article investigates the characteristics of the newly created business model, both from a theoretical perspective and by analysing several case studies. A particular attention will be granted to the evolution of the Romanian carrier Blue Air towards the “hybrid” model. The article focuses on determining the position of the “hybrid” airline in a market with carriers situated along both sides of this business model: lower cost vs. “better” experience and raises the question on how value can be generated in this context. Another aspect tackled is the understanding of the new segmentation of the market, as a consequence of the development of the new business model. In order to achieve this purpose, a survey has been conducted, aiming to mark out the travel preferences of the passengers travelling through the Henri Coandă International Airport.

2006-01-01

Much research has been carried out to evaluate the impact of strategic alliance membership on the performance of airlines. However it would be of interest to identify how airlines perceive this impact in terms of branding by each of the three global alliance groupings. It is the purpose of this paper to gather the opinion of airlines, belonging to the three strategic alliance groups, on the impact that the strategic alliance brands have had on their individual brands and how do they perceive that this impact will change in the future. To achieve this, a comprehensive survey of the alliance management and marketing departments of airlines participating in the three global strategic alliances was required. The results from this survey give an indication whether the strategic airline alliances, which are often referred to as marketing agreements, enhance, damage or have no impact on the individual airline brands.

An Opportunity for Hydrogen Fueled Supersonic Airliners

Directory of Open Access Journals (Sweden)

Alex Forbes

2011-02-01

Full Text Available This paper takes a new look at the prospects for developing supersonic civil airliners, considering global demographics, climate change issues, fuel prices and technological advances. Dramatic changes have occurred in the demographics, economics, and market intensity of the Eastern Hemisphere since the 1990s. Carbon reduction imperatives provide a major incentive to invest in developing hydrogen-fueled airliners. The “point-to-point” air route architecture has proved viable with long range mid-size airliners. With a cruise Mach number of 1.4, a large number of destinations become viable for overland supersonic flight. A conceptual design process is used to estimate cost per seat mile for a range of hydrocarbon and hydrogen fuel costs. An argument based on the ideal shape for minimal wave drag, estimates the drag penalty from using hydrogen. Viable aircraft geometries are shown to exist, that match the theoretical ideal shape, showing that the drag estimate is achievable. Conservative design arguments and market estimates suggest that hydrogen-fueled airliners can achieve seat-mile costs low enough to open a large worldwide market and justify a viable fleet size.

Energy management in the Canadian airline industry

Energy Technology Data Exchange (ETDEWEB)

1982-09-01

The purpose of this report was to outline the current status of the Canadian airline industry's energy performance and to outline energy management programs undertaken within the industry. The study also provides an aviation energy management information base developed through a comprehensive computer bibliographical review. A survey of the industry was undertaken, the results of which are incorporated in this report. The Canadian airline industry has recognized the importance of energy management and considerable measures have been introduced to become more energy efficient. The largest single contributor to improved productivity is the acquisition of energy efficient aircraft. Larger airlines in particular have implemented a number of conservation techniques to reduce fuel consumption. However, both large and small airlines would further benefit through incorporating techniques and programs described in the annotated bibliography in this study. Rising fuel prices and economic uncertainties will be contributing factors to a smaller average annual growth in fuel consumption during the 1980s. The lower consumption levels will also be a result of continuing energy conservation awareness, new technology improvements, and improvements in air traffic control. 98 refs., 4 figs., 6 tabs.

Impact of environmental constraints and aircraft technology on airline fleet composition

Science.gov (United States)

Moolchandani, Kushal A.

This thesis models an airline's decisions about fleet evolution in order to maintain economic and regulatory viability. The aim is to analyze the fleet evolution under different scenarios of environmental policy and technology availability in order to suggest an optimal fleet under each case. An understanding of the effect of aircraft technologies, fleet size and age distribution, and operational procedures on airline performance may improve the quality of policies to achieve environmental goals. Additionally, the effect of decisions about fleet evolution on air travel is assessed as the change in market demand and profits of an abstracted, benevolent monopolist airline. Attention to the environmental impact of aviation has grown, and this has prompted several organizations such as ICAO (and, in response, NASA) to establish emissions reduction targets to reduce aviation's global climate impact. The introduction of new technology, change in operational procedures, etc. are some of the proposed means to achieve these targets. Of these, this thesis studies the efficacy of implementation of environmental policies in form of emissions constraints as a means to achieve these goals and assesses their impact on an airline's fleet evolution and technology use (along with resulting effects on air travel demand). All studies in this thesis are conducted using the Fleet-level Environmental Evaluation Tool (FLEET), a NASA sponsored simulation tool developed at Purdue University. This tool models airline operational decisions via a resource allocation problem and uses a system dynamics type approach to mimic airline economics, their decisions regarding retirement and acquisition of aircraft and evolution of market demand in response to the economic conditions. The development of an aircraft acquisition model for FLEET is a significant contribution of the author. Further, the author conducted a study of various environmental policies using FLEET. Studies introduce constraints on

Raghavan, Sunder

2003-01-01

Competition in the airline industry has been fierce since the industry was deregulated in 1978. The proponents of deregulation believed that more competition would improve efficiency and reduce prices and bring overall benefits to the consumer. In this paper, a case is made based on core theory that under certain demand and cost conditions more competition can actually lead to harmful consequences for industries like the airline industry or cause an empty core problem. Practices like monopolies, cartels, price discrimination, which is considered inefficient allocation of resources in many other industries, can actually be beneficial in the case of the airline industry in bringing about an efficient equilibrium.

The Role of Budget Airlines in the Air Transport Market

Directory of Open Access Journals (Sweden)

Panasiuk Irina P.

2017-05-01

Full Text Available The contemporary air transport market has been considered and analyzed, key aspects of the emergence of budget airlines (low-cost in the air transport market have been highlighted. The main factors of influence on their functioning and international distribution have been allocated. On exploring the air transport market, it can be argued that low-cost airlines are gaining speed and spreading all around the world. This system was developed specifically for budget tourists and is particularly popular among students. Budget airlines are a profitable alternative to expensive airfares. As a rule, low-cost airlines refuse most traditional services to reduce the cost of transporting passengers, and hence the prices of flights. In the current phase of operation of the budget airlines, it is particularly necessary to study the reasons for such charity and the efficiency factor in providing cheap airfares. In spite of the tempting offer, there are some nuances that are subject of research.

Industry Consolidation and Future Airline Network Structures in Europe

Science.gov (United States)

Dennis, Nigel

2003-01-01

In the current downturn in demand for air travel, major airlines are revising and rationalizing their networks in an attempt to improve financial performance and strengthen their defences against both new entrants and traditional rivals. Expansion of commercial agreements or alliances with other airlines has become a key reaction to the increasingly competitive marketplace. In the absence, for regulatory reasons, of cross-border mergers these are the principal means by which the industry can consolidate internationally. This paper analyzes the developments which have been taking place and attempts to itentify the implications for airline network structures and the function of different hub airports. The range of services available to passengers in long-haul markets to/from Europe is evaluated before and after recent industry reorganization. Hubs are crucial to interlink the route networks of parmers in an alliance. However, duplication between nearby hub airports that find themselves within the same airline alliance can lead to loss of service at the weaker locations. The extent to which the alliance hubs in Europe duplicate or complement each other in terms of network coverage is assessed and this methodology also enables the optimal partnerships for "unattached" airlines to be identified. The future role of the various European hubs is considered under different scenarios of global alliance development. The paper concludes by considering possible longer-term developments. In an environment where the low-cost carriers will provide a major element of customer choice, it is suggested that the traditional airlines will retrench around their hubs, surrendering many secondary cities to the low-cost sector. Further reduction in the number of alliances could threaten more of the European hubs. For both regulatory and commercial reasons, the end result may be just one airline alliance - so recreating in the deregulated market the historic rule of IATA.

The Study of Airline Merger and Acquisition in the Great China Area

Science.gov (United States)

Shon, Zhengyi

2003-01-01

The Asian financial crisis in the late 20 th century has some long lasting effect on the air transportation industry in Asia, especially in the Great China Area. Starting from 1998, airlines in both China and Taiwan suffered some serious financial losses due to the diminishing travel demand caused by the economic recession. Airlines were forced to cut price to attract passengers and hence crashed the market discipline. A number of airline mergers and acquisitions were then driven by the markets and the governments. After China and Taiwan have both entered the World Trade Organization, some mega-merging cases were finalized in late 2002 for better fitting the world's aviation competitions. This paper reviews the nine merging and acquiring cases in the Great China Area in the past 5 years. Almost all the airlines in the area were involved. The new groups of airlines and the survival airlines are introduced. Market response to the airline mergers will also be examined. A general look over the performance of the new airlines will be discussed. And the future of the market will also be analyzed. Finally, the practices and the impacts of current inter-state mergers in the Great China Area will be examined. The study has expected a highly concentrated domestic market in both China and Taiwan. Each of the market will be dominated by three major airline groups of their own. Cross-holding equity within these 6 leading aviation groups would also be possible after further deregulations.

An analytical model for the assessment of airline expansion strategies

Mauricio Emboaba Moreira

2014-01-01

Full Text Available Purpose: The purpose of this article is to develop an analytical model to assess airline expansion strategies by combining generic business strategy models with airline business models. Methodology and approach: A number of airline business models are examined, as are Porter’s (1983 industry five forces that drive competition, complemented by Nalebuff/ Brandenburger’s  (1996 sixth force, and the basic elements of the general environment in which the expansion process takes place.  A system of points and weights is developed to create a score among the 904,736 possible combinations considered. The model’s outputs are generic expansion strategies with quantitative assessments for each specific combination of elements inputted. Originality and value: The analytical model developed is original because it combines for the first time and explicitly elements of the general environment, industry environment, airline business models and the generic expansion strategy types. Besides it creates a system of scores that may be used to drive the decision process toward the choice of a specific strategic expansion path. Research implications: The analytical model may be adapted to other industries apart from the airline industry by substituting the element “airline business model” by other industries corresponding elements related to the different specific business models.

Bogdan AVRAM

2013-12-01

Full Text Available More and more airlines are trying to show their customers their ability to understand their needs, the market trends and the importance of technology in their lives. In response to the rapid development of the consumer electronics, the airline companies focus their attention on offering their customers the possibility to book a flight or check-in using a smartphone, spend time watching movies or be connected to the internet during the flight. Customers search for airlines who are more ”tech-geek” and opened to new technologies, which allows them to rate the airline companies through apps or connect more often with the airline through social-media. Technology has become an important part in developing and marketing the airline services for a better quality, more customer-focused and for better flight experience which ultimately makes the difference when choosing to fly an airline company.

Fatigue mitigation effects of en-route napping on commercial airline pilots flying international routes

Science.gov (United States)

Baldwin, Jarret Taylor

The introduction of ultra-long range commercial aircraft and the evolution of the commercial airline industry has provided new opportunities for air carriers to fly longer range international route segments while deregulation, industry consolidation, and the constant drive to reduce costs wherever possible has pressured airline managements to seek more productivity from their pilots. At the same time, advancements in the understanding of human physiology have begun to make their way into flight and duty time regulations and airline scheduling practices. In this complex and ever changing operating environment, there remains an essential need to better understand how these developments, and other daily realities facing commercial airline pilots, are affecting their fatigue management strategies as they go about their rituals of getting to and from their homes to work and performing their flight assignments. Indeed, the need for commercial airline pilots to have access to better and more effective fatigue mitigation tools to combat fatigue and insure that they are well rested and at the top of their game when flying long-range international route segments has never been greater. This study examined to what extent the maximum fatigue states prior to napping, as self-accessed by commercial airline pilots flying international route segments, were affected by a number of other common flight assignment related factors. The study also examined to what extent the availability of scheduled en-route rest opportunities, in an onboard crew rest facility, affected the usage of en-route napping as a fatigue mitigation strategy, and to what extent the duration of such naps affected the perceived benefits of such naps as self-accessed by commercial airline pilots flying international route segments. The study utilized an online survey tool to collect data on crew position, prior flight segments flown in the same duty period, augmentation, commuting, pre-flight rest obtained in the

Liou, James J. H.; Tzeng, Gwo-Hshiung

Human resource management (HRM) is an important issue for today’s competitive airline marketing. In this paper, we discuss a multi-objective model designed from the De Novo perspective to help airlines optimize their maintenance manpower portfolio. The effectiveness of the model and solution algorithm is demonstrated in an empirical study of the optimization of the human resources needed for airline line maintenance. Both De Novo and traditional multiple objective programming (MOP) methods are analyzed. A comparison of the results with those of traditional MOP indicates that the proposed model and solution algorithm does provide better performance and an improved human resource portfolio.

Strategic Classification and Examination of the Development of Current Airline Alliance Activities

Science.gov (United States)

Wang, Zhi H.; Evans, Michael

2002-01-01

Previous research argues that despite the fact that strategic alliances have become an important feature of the world airline industry, little rigorous analysis has been done on the effects of these alliances. This is partially because there is a lack of precise definitions to specify different types of airline alliances in the literature. This research identifies several categories of airline alliances through a strategic classification of the current alliance activities involving the major airlines for the period 1989 to 1999. The classification enables this research to examine how strategic alliance activities are evolving, particularly to compare how airlines in North America, the European Union and the Asia Pacific region have committed to different alliances. Findings show that there is a significant difference between the number and scope of alliances adopted in the three aviation markets. These findings facilitate research to further analyse the impact of market liberalization on various formations of strategic airline alliances.

The occurrence of Salmonella in airline meals.

Science.gov (United States)

Hatakka, M; Asplund, K

1993-01-01

The occurrence of Salmonella in airline meals was studied in 1989-1992. Samples were collected from flight kitchens in 29 countries. The material consisted of 400 cold dishes and 1,288 hot dishes as well as salads, cheese plates and deserts. Total number of samples was 2211. Salmonella spp. were isolated from 6 samples; 1 contaminated sample was a cold dish prepared in Bangkok, 1 was a hot dish prepared in Mombasa and the remaining 4 contaminated samples were hot dishes prepared within one week in Beijing. The isolated serotypes were S. ohio, S. manchester and S. braenderup. The contaminated cold dish prepared by a flight kitchen in Bangkok was found to be connected with a Salmonella outbreak which occurred in Finland in 1990. Cold airline dishes containing food of animal origin seems to be more risky as a source of Salmonella infections among airline passengers.

Baseline energy forecasts and analysis of alternative strategies for airline fuel conservation

Energy Technology Data Exchange (ETDEWEB)

1976-01-01

The objectives of this study were to identify measures to reduce airline fuel consumption and to evaluate the impact of these alternatives on fuel consumption through 1990. To evaluate the impact of fuel conservation strategies, baseline forecasts of airline activity and energy consumption to 1990 were developed. Alternative policy options to reduce fuel consumption were identified and analyzed for three baseline levels of aviation activity within the framework of an aviation activity/energy consumption model. By combining the identified policy options, a strategy was developed to provide incentives for airline fuel conservation. Strategies and policy options were evaluated in terms of their impact on airline fuel conservation and the functioning of the airline industry as well as the associated social, environmental, and economic costs. The need for strategies to conserve airline fuel is based on air transportation's dependence upon petroleum; the current lack of alternative energy sources; the potential for disruption of air service due to crises in fuel availability such as experienced during the OPEC oil embargo; and the overall national goal of energy independence through energy conservation in all consuming sectors. The transition from the current situation to that described by strategies and policy options may require difficult adjustments by the airline industry in the short term. In the long term, however, conservation strategies can enhance the health of the airline industry as well as its fuel efficiency.

Prevalence of fatigue in a group of airline pilots.

Science.gov (United States)

Reis, Cátia; Mestre, Catarina; Canhão, Helena

2013-08-01

Fatigue is a common phenomenon in airline pilots that can impair alertness and ability of crewmembers to safely operate an aircraft and perform safety related tasks. Fatigue can increase the risk of an incident or even an accident. This study provides the first prevalence values for clinically significant fatigue in Portuguese airline pilots. The hypothesis that medium/short-haul pilots may currently present different levels of fatigue than long-haul pilots was also tested. A survey was conducted by requesting Portuguese airline pilots to complete questionnaires placed in the pilots' personal lockers from 1 April until 15 May 2012. The questionnaire included the self-response Fatigue Severity Scale (FSS) to measure subjective fatigue and some additional questions concerning perception of fatigue by pilots. The prevalence values for total and mental fatigue achieved in the Portuguese airline pilots were: 89.3% (FSS > or = 4) and 94.1% (FSS > or = 4) when splitting the sample in two subsamples, long- and medium/short-haul pilots. Levels of total and mental fatigue were higher for medium/short-haul pilots. The analysis of fatigue levels in each type of aviator showed that medium/short-haul pilots presented the highest levels of total and mental fatigue. This study produced the first prevalence values of total and mental fatigue among Portuguese airline pilots, which represents a great step to understanding and addressing this critical phenomenon.

Karamata Ema

2017-01-01

Full Text Available One of the most remarkable tendencies on the market of airline services is that nowadays almost every airline company strive to build long-term relationships with customers/users of airline services through loyalty programs. The subject of the paper is to explore the role of Frequent Flyer Programs (FFPs in the scope of customer relationship management in airline industry and to determine whether affiliation to FFPs affects customers to buy tickets from the same airline carrier. For this purpose, an empirical analysis was conducted based on the data obtained from the survey conducted at the Belgrade airport Nikola Tesla, in September 2015. Hypothesis is formed in accordance with the stated aim of the work and was tested by using descriptive and graphical presentation as well as Chi-square statistical test. The results have shown that loyalty programs influence customers when choosing airlines, meaning that Frequent Flyer members tend to use air transportation services of airline carriers which are part of Frequent Flyer Program they belong to, whenever price and timing suit them. Furthermore, the chance of choosing the airline whose Frequent Flyer Program one is member of, increases proportionally to the length of membership and, more importantly, the number of flights that one has realized so far. Based on the tested hypothesis and observed preferences of the travelers, possible marketing implications of the results are pointed out in this article, as well as the analysis of the status and rating of our national airline according to surveyed passengers.

Building customer relationships as retention strategy in the South African domestic passenger airline industry

Directory of Open Access Journals (Sweden)

Pierre Mostert

2010-12-01

Full Text Available Organisations are increasingly focusing on building long-term relationships with customers, thereby increasing their probability for success by offering customers higher levels of satisfaction, increasing customer loyalty, and ultimately retaining customers. Airlines in particular can benefit from retaining customers as the airline industry is characterised by fierce competition and many airlines are finding it difficult to survive against the backdrop of enormous challenges in the past decade, including the significant decline in demand for air travel together with rising costs and the worldwide economic downturn. This study investigates the effect which a strategy by airlines of building relationships with customers has on customer satisfaction, loyalty, and ultimately customer retention. The effect of service failures on customers' relationships with airlines are also considered as a negative experience could results in customers defecting to competitors. A questionnaire, comprising six sections, was specifically compiled to determine customer retention in the South African domestic passenger airline industry. Data were collected by trained fieldworkers from OR Tambo International Airport by means of a non-probability convenience sampling method from 324 passengers flying with the various domestic airlines. Findings indicate that most respondents were satisfied with the airlines' overall service; respondents who formed relationships with domestic airlines were more loyal toward the airlines; and the relationships of respondents who were satisfied with airlines' service recovery efforts were either strengthened or unchanged. The findings from this study support findings from international studies by providing a unique South African perspective on the effect of a strategy of building relationships with customers on their satisfaction, loyalty and ultimately retention. It can therefore be recommended that the organisations competing in the South

To determine the source of an international outbreak of shigellosis associated with consumption of food served by a Minnesota-based airline. Cohort studies of players and staff of a Minnesota-based professional football team and passengers on flights with a confirmed case of outbreak-associated Shigella sonnei infection. Community- and industry-based studies conducted from October through November 1988. Sixty-five football team players and staff, and 725 airline passengers in the cohort studies. Twenty-one (32%) of 65 football players and staff developed shigellosis that was associated with consumption of cold sandwiches prepared at the airline flight kitchen (relative risk [RR], 17.1; 95% confidence interval [Cl], 2.4 to 120; P airline passengers, and flight attendants. Thirty (4.1%) of 725 passengers on 13 flights with confirmed cases had confirmed or probable shigellosis. Illness was associated with consumption of cold food items served on the flights and prepared by hand at the airline flight kitchen (RR, 5.7; 95% Cl, 1.4 to 23.5; P food items or elimination of these items from menus.

Airline Safety Improvement Through Experience with Near-Misses: A Cautionary Tale.

Science.gov (United States)

Madsen, Peter; Dillon, Robin L; Tinsley, Catherine H

2016-05-01

In recent years, the U.S. commercial airline industry has achieved unprecedented levels of safety, with the statistical risk associated with U.S. commercial aviation falling to 0.003 fatalities per 100 million passengers. But decades of research on organizational learning show that success often breeds complacency and failure inspires improvement. With accidents as rare events, can the airline industry continue safety advancements? This question is complicated by the complex system in which the industry operates where chance combinations of multiple factors contribute to what are largely probabilistic (rather than deterministic) outcomes. Thus, some apparent successes are realized because of good fortune rather than good processes, and this research intends to bring attention to these events, the near-misses. The processes that create these near-misses could pose a threat if multiple contributing factors combine in adverse ways without the intervention of good fortune. Yet, near-misses (if recognized as such) can, theoretically, offer a mechanism for continuing safety improvements, above and beyond learning gleaned from observable failure. We test whether or not this learning is apparent in the airline industry. Using data from 1990 to 2007, fixed effects Poisson regressions show that airlines learn from accidents (their own and others), and from one category of near-misses-those where the possible dangers are salient. Unfortunately, airlines do not improve following near-miss incidents when the focal event has no clear warnings of significant danger. Therefore, while airlines need to and can learn from certain near-misses, we conclude with recommendations for improving airline learning from all near-misses. © 2015 Society for Risk Analysis.

2017-04-01

Full Text Available Purpose: This article aims to apply to the case of Avianca Airlines the Analytical Model for the Assessment of Airline Expansion Strategies developed by Moreira (2014 in order to explain the rationale of the expansion strategy followed by this airline and indicate other possible expansion strategies.  Design/methodology/approach: This article is a case study in the sense that it aims to arrive to broad generalizations based on the collected evidences, focusing on one of the most traditional airlines in the world. This article is a positivist case study, based in the positivist understanding; because it is supported by objective facts of the situation which are informed by the researcher’s interpretive understanding according to it is recommended for this type of study. Findings: The application of the Analytical Model for the Assessment of Airline Expansion Strategies above referred was successful, considering that the model was able to explain a wide range of complex aspects of the Avianca’s development. Thus, being one of the oldest airlines in continued operation in the world, the expansion process of this airline is connected to many political, sociological and economic facets - ie., its general environment - of its mother country, Colombia. The analytical model offered the opportunity to explore these issues in a detailed manner, adding a broader comprehension of this airline that goes beyond its operating and economic analysis. Originality/value: They reside on the fact that this is the first time that this analytical model is applied to study extensively an actual situation. Besides, airlines in Latin America have not been widely covered by the academia and this is an opportunity to begin to fill this gap. Furthermore, the referred analytical model is applicable to organizations or firms that operate in other industries if the proper adjustments are made. Implications: The implications for the academic research are to understand that

Full Text Available This paper focuses on evaluating airline service quality from the perspective of passengers' view. Until now a lot of researches has been performed in airline service quality evaluation in the world but a little research has been conducted in Iran, yet. In this study, a framework for measuring airline service quality in Iran is proposed. After reviewing airline service quality criteria, SSQAI model was selected because of its comprehensiveness in covering airline service quality dimensions. SSQAI questionnaire items were redesigned to adopt with Iranian airlines requirements and environmental circumstances in the Iran's economic and cultural context. This study includes fuzzy decision-making theory, considering the possible fuzzy subjective judgment of the evaluators during airline service quality evaluation. Fuzzy TOPSIS have been applied for ranking airlines service quality performances. Three major Iranian airlines which have the most passenger transfer volumes in domestic and foreign flights were chosen for evaluation in this research. Results demonstrated Mahan airline has got the best service quality performance rank in gaining passengers' satisfaction with delivery of high-quality services to its passengers, among the three major Iranian airlines. IranAir and Aseman airlines placed in the second and third rank, respectively, according to passenger's evaluation. Statistical analysis has been used in analyzing passenger responses. Due to the abnormality of data, Non-parametric tests were applied. To demonstrate airline ranks in every criterion separately, Friedman test was performed. Variance analysis and Tukey test were applied to study the influence of increasing in age and educational level of passengers on degree of their satisfaction from airline's service quality. Results showed that age has no significant relation to passenger satisfaction of airlines, however, increasing in educational level demonstrated a negative impact on

Vaccines and Airline Travel: A Federal Role to Protect the Public Health.

Science.gov (United States)

Robertson, Christopher T

2016-05-01

This Article explores two ways in which airline travel is an important vector for the spread of infectious disease, and argues that airlines have market-based and liability-based reasons to require that passengers be vaccinated. Going further, the Article explores whether the federal government has the legal and constitutional authority-especially under the Commerce Clause-to encourage or mandate that airlines implement such a vaccine screen. By disrupting the spread of disease at key network nodes where individuals interact and then connect with other geographic regions, and by creating another incentive for adult vaccination, an airline vaccine screen could be an effective and legally viable tool for the protection of public health.

Minimal data exist on the prevalence and characteristics of in-flight reactions to foods. To characterize reactions to foods experienced by passengers aboard commercial airplanes and to examine information about flying with a food allergy available from airlines. Telephone questionnaires were administered to individuals in a peanut, tree nut, and seed allergy database who self-reported reactions aboard aircraft. Airlines were contacted to obtain information on food allergy policies. Forty-one of 471 individuals reported allergic reactions to food while on airplanes, including 4 reporting more than 1 reaction. Peanuts accounted for most of the reactions. Twenty-one individuals (51%) treated their reactions during flight. Only 12 individuals (29%) reported the reaction to a flight attendant. Six individuals went to an emergency department after landing, including 1 after a flight diversion. Airline personnel were notified of only 3 of these severe reactions. Comparison of information given to 3 different investigators by airline customer service representatives showed that inconsistencies regarding important information occurred, such as whether the airline regularly serves peanuts. In this group of mainly adults with severe nut/seed allergy, approximately 9% reported experiencing an allergic reaction to food while on board an airplane. Some reactions were serious and potentially life-threatening. Individuals commonly did not inform airline personnel about their experiences. In addition, the quality of information about flying with food allergies available from customer service departments is highly variable and, in some cases, incomplete or inaccurate.

Complaints as starting point for vicious cycles in customer-employee-interactions.

Science.gov (United States)

Traut-Mattausch, Eva; Wagner, Sara; Pollatos, Olga; Jonas, Eva

2015-01-01

A ring-model of vicious cycles in customer-employee-interaction is proposed: service employees perceive complaints as a threat to their self-esteem resulting in defense responses such as an increased need for cognitive closure, a devaluation of the customer and their information and degrading service behavior. Confronted with such degrading service behavior, customers react defensively as well, by devaluing the employee for example with regard to his/her competence and by reducing repurchase and positive word-of-mouth (WOM). Three studies investigated each link in this ring-model. In study 1, participants were confronted with an aggressive or neutral customer complaint. Results show that motivated closed-mindedness (one aspect of the need for cognitive closure) increases after an aggressive complaint leading to a devaluation of the customer and their information, and in turn to a degrading service reaction. In study 2, participants were confronted with a degrading or favorable service reaction. Results show that they devaluate the employees' competence after receiving a degrading service reaction and thus reduce their intention to repurchase. In study 3, we finally examined our predictions investigating real customer-employee-interactions: we analyzed data from an evaluation study in which mystery callers tested the service hotline of an airline. Results show that the employees' competence is devaluated after degrading behavior and thus reduces positive WOM.

2017-02-01

Full Text Available Purpose: This paper offer marketing strategy suggestion to the airlines operating within the Thai aviation market. It identifies the recommended motivational factors that influence the airline customers’ decision to their airline choices. Airlines use different customer relationship management programs to attract returning customers.  This paper suggested the most attractive motivation factors for Thailand's air travel market. Design/methodology/approach: This research paper is an attempt to study and identify the factors, including loyalty program, distribution channel, customer services, promotions and other influence causes that affected the customer preference in the airline ticket purchasing behavior in Thailand. A questionnaire survey was conducted with the sample identified through unrestricted non probability sampling technique at four major airports in Thailand. The data collected are analyzed to identify the favorable drivers that lead to customer decision on airline choice. Findings: The result from the study has demonstrated that price, and promotion has a significant impact on customer preference and positively leads to repurchase intention for their future travel. Moreover, flight schedules are also a main factor influencing the travelers’ final decision on airline choice. However, when the promotional strategies and schedule are comparable between airlines, customers are attracted by the airline amenities and services. Loyalty program (frequent-flier program flier program is showing a less attractive motivator while distribution channel demonstrates the least important affecting the travelers’ choice of airline. Originality/value: The paper begins with an overview of previous research in the area of airlines customer relationship management and then moves on to what is currently being implemented by the airlines. The authors then propose several customer relationship strategies and identify the most attractive one that

Estimation of Airline Benefits from Avionics Upgrade under Preferential Merge Re-sequence Scheduling

Science.gov (United States)

Kotegawa, Tatsuya; Cayabyab, Charlene Anne; Almog, Noam

2013-01-01

Modernization of the airline fleet avionics is essential to fully enable future technologies and procedures for increasing national airspace system capacity. However in the current national airspace system, system-wide benefits gained by avionics upgrade are not fully directed to aircraft/airlines that upgrade, resulting in slow fleet modernization rate. Preferential merge re-sequence scheduling is a best-equipped-best-served concept designed to incentivize avionics upgrade among airlines by allowing aircraft with new avionics (high-equipped) to be re-sequenced ahead of aircraft without the upgrades (low-equipped) at enroute merge waypoints. The goal of this study is to investigate the potential benefits gained or lost by airlines under a high or low-equipped fleet scenario if preferential merge resequence scheduling is implemented.

We propose a probabilistic growth model for transport networks which employs a balance between popularity of nodes and the physical distance between nodes. By comparing the degree of each node in the model network and the World Airline Network (WAN), we observe that the difference between the two is minimized for α≈2. Interestingly, this is the value obtained for the node-node correlation function in the WAN. This suggests that our model explains quite well the growth of airline networks.

A study of the financial history of the U.S. scheduled airlines and the improvement of airline profitability through technology

Science.gov (United States)

Wilcox, D. E.

1975-01-01

The financial history of the U.S. scheduled airline industry was investigated to determine the causes of the erratic profit performance of the industry and to evaluate potential economic gains from technology advances of recent years. Operational and economic factors affecting past and future profitability of the industry are discussed, although no attempt was made to examine the profitability of individual carriers. The results of the study indicate that the profit erosion of the late 1960's and early 1970's was due more to excess capacity than to inadequate fare levels, but airline problems were severely compounded by the rapid fuel price escalation in 1974 and 1975. Near-term solutions to the airline financial problems depend upon the course of action by the industry and the CAB and the general economic health of the nation. For the longer term, the only acceptable alternative to continued fare increases is a reduction in unit operating costs through technological advance. The next generation of transports is expected to incorporate technologies developed under Government sponsorship in the 1960's and 1970's with significant improvements in fuel consumption and operating costs.

Modeling the impact of improved aircraft operations technologies on the environment and airline behavior

Science.gov (United States)

Foley, Ryan Patrick

The overall goal of this thesis is to determine if improved operations technologies are economically viable for US airlines, and to determine the level of environmental benefits available from such technologies. Though these operational changes are being implemented primarily with the reduction of delay and improvement of throughput in mind, economic factors will drive the rate of airline adoption. In addition, the increased awareness of environmental impacts makes these effects an important aspect of decision-making. Understanding this relationship may help policymakers make decisions regarding implementation of these advanced technologies at airports, and help airlines determine appropriate levels of support to provide for these new technologies. In order to do so, the author models the behavior of a large, profit-seeking airline in response to the introduction of advanced equipage allowing improved operations procedures. The airline response included changes in deployed fleet, assignment of aircraft to routes, and acquisition of new aircraft. From these responses, changes in total fleet-level CO2 emissions and airline profit were tallied. As awareness of the environmental impact of aircraft emissions has grown, several agencies (ICAO, NASA) have moved to place goals for emissions reduction. NASA, in particular, has set goals for emissions reduction through several areas of aircraft technology. Among these are "Operational Improvements," technologies available in the short-term through avionics and airport system upgrades. The studies in this thesis make use of the Fleet-Level Environmental Evaluation Tool (FLEET), a simulation tool developed by Purdue University in support of a NASA-sponsored research effort. This tool models the behavior of a large, profit-seeking airline through an allocation problem. The problem is contained within a systems dynamics type approach that allows feedback between passenger demand, ticket price, and the airline fleet composition

Financial Comparisons across Different Business Models in the Canadian Airline Industry

Science.gov (United States)

Flouris, Triant; Walker, Thomas

2007-01-01

This paper examines the accounting and stock price performance of two Canadian airlines, WestJet and Air Canada, over a five year period, taking into account the aftermath of the systemic shock to the airline industry produced by the September 11, 2001 (9-11), terrorist attacks and subsequent events such as the 2002 SARS outbreak, the wars in Afghanistan and Iraq, and the accompanying rise in jet fuel prices. Our study focuses on the viability of low-cost versus conventional-cost business models in Canada under the current business environment and the ability of airlines to withstand and effectively respond to catastrophic industry events. Furthermore, we link the effectiveness of the airlines responses to these events to specific elements of their respective business models. We test our hypothesis through a case study. We focus on WestJet as a typical low-cost airline and compare its accounting and stock performance to Air Canada, a legacy carrier and rival in several business sectors. We find WestJet to be much less affected by catastrophic industry events. By decomposing each airline s return volatility, we observe that WestJet s systematic and unsystematic risk increased only slightly during the industry's post-9-11 turmoil when compared to Air Canada. In addition, we find that both WestJet s accounting and stock performance have been highly superior to those of Air Canada. We argue that WestJet s business model provides the firm with significantly more financial and operational flexibility than its legacy rival, Air Canada. WestJet's lower operating costs, high consumer trust, product offering, corporate structure, workforce and work practices, as well as operational procedures are all factors that appear to contribute to its relative success.

2014-01-01

Current employees provide the best examples of the type of aptitude, attitude, motivation, and fit we are looking for, or not looking for, in new employees. All four of these attributes are present in star employees. Using what we know about our best and worst employees can assist us in developing questions and scoring templates that will help us categorize current applicants. Hiring managers should formulate questions in a way that elicits informative responses from candidates about past performance in situations similar to those they will face on the job. Nonverbal clues can help provide insight beyond the simple verbal answer given by candidates. Practice, critique, and critical review of the outcomes of our hiring decisions improve our ability to become good hiring managers.

Full Text Available The revolutionary alterations and conversions occurring in information and communication technologies, have triggered an increase in the electronic commerce applications. Airline tickets are one of the most popular items purchased on the internet. The airline websites have become a big distribution channel for the companies to sustain their competitiveness. At this moment, the competition is increasing as airlines try to acquire and retain customers in the airline industry. To acquire and retain customers in such a highly competitive market, it is important for airlines to understand their relative levels of quality in terms of critical elements affecting their competitive advantages. In this study, an integrated two-stage multi-criteria decision-making techniques were used for the measurement of the performance of the airline websites using the Entropy Weight Method and the Grey Relational Analysis approach. The performance of 11 airline companies’ websites operating in Turkey was evaluated in terms of seven criteria.

Full Text Available This research aims to investigate the different social media strategies adopted by the airline companies from two European regions. In the attempt to land more customers on their social media runway, drive more sales from social media content, increase customer satisfaction through a high response rate or increase their brand awareness, the airlines combine creativity and high-quality ideas to better promote their products and services to customers all around the globe. The paper analyses the content (number of fans, posts, number of likes, the dynamics of comments, response rate on the Facebook pages of Tarom, Blue Air, Wizz Air, Lufthansa, Austrian Airlines, KLM International and Air Europa on a one week period (10th February – 18th February 2014 and successful practices on social media. The paper also aims to provide solutions for airlines to better connect with their passengers and effectively use the social media environment to increase sales and customer satisfaction.

Examining the Relationship Between Passenger Airline Aircraft Maintenance Outsourcing and Aircraft Safety

Science.gov (United States)

Monaghan, Kari L.

The problem addressed was the concern for aircraft safety rates as they relate to the rate of maintenance outsourcing. Data gathered from 14 passenger airlines: AirTran, Alaska, America West, American, Continental, Delta, Frontier, Hawaiian, JetBlue, Midwest, Northwest, Southwest, United, and USAir covered the years 1996 through 2008. A quantitative correlational design, utilizing Pearson's correlation coefficient, and the coefficient of determination were used in the present study to measure the correlation between variables. Elements of passenger airline aircraft maintenance outsourcing and aircraft accidents, incidents, and pilot deviations within domestic passenger airline operations were analyzed, examined, and evaluated. Rates of maintenance outsourcing were analyzed to determine the association with accident, incident, and pilot deviation rates. Maintenance outsourcing rates used in the evaluation were the yearly dollar expenditure of passenger airlines for aircraft maintenance outsourcing as they relate to the total airline aircraft maintenance expenditures. Aircraft accident, incident, and pilot deviation rates used in the evaluation were the yearly number of accidents, incidents, and pilot deviations per miles flown. The Pearson r-values were calculated to measure the linear relationship strength between the variables. There were no statistically significant correlation findings for accidents, r(174)=0.065, p=0.393, and incidents, r(174)=0.020, p=0.793. However, there was a statistically significant correlation for pilot deviation rates, r(174)=0.204, p=0.007 thus indicating a statistically significant correlation between maintenance outsourcing rates and pilot deviation rates. The calculated R square value of 0.042 represents the variance that can be accounted for in aircraft pilot deviation rates by examining the variance in aircraft maintenance outsourcing rates; accordingly, 95.8% of the variance is unexplained. Suggestions for future research include

The effectiveness of airline pilot training for abnormal events.

Science.gov (United States)

Casner, Stephen M; Geven, Richard W; Williams, Kent T

2013-06-01

To evaluate the effectiveness of airline pilot training for abnormal in-flight events. Numerous accident reports describe situations in which pilots responded to abnormal events in ways that were different from what they had practiced many times before. One explanation for these missteps is that training and testing for these skills have become a highly predictable routine for pilots who arrive to the training environment well aware of what to expect. Under these circumstances, pilots get plentiful practice in responding to abnormal events but may get little practice in recognizing them and deciding which responses to offer. We presented 18 airline pilots with three abnormal events that are required during periodic training and testing. Pilots were presented with each event under the familiar circumstances used during training and also under less predictable circumstances as they might occur during flight. When presented in the routine ways seen during training, pilots gave appropriate responses and showed little variability. However, when the abnormal events were presented unexpectedly, pilots' responses were less appropriate and showed great variability from pilot to pilot. The results suggest that the training and testing practices used in airline training may result in rote-memorized skills that are specific to the training situation and that offer modest generalizability to other situations. We recommend a more complete treatment of abnormal events that allows pilots to practice recognizing the event and choosing and recalling the appropriate response. The results will aid the improvement of existing airline training practices.

The impact of Southwest Airline's contribution to atmospheric Carbon Dioxide and Nitrous Oxide totals

Wilkerson, Cody L.

Over the last century, aviation has grown to become an economical juggernaut. The industry creates innovation, connects people, and maintains a safety goal unlike any other field. However, as the world becomes more populated with technology and individuals, a general curiosity as to how human activity effects the planet is becoming of greater interest. This study presents what one domestic airline in the United States, Southwest Airlines, contributes to the atmospheric make-up of the planet. Utilizing various sources of quantifiable data, an outcome was reached that shows the amount of Carbon Dioxide and Nitrous Oxide produced by Southwest Airlines from 2002 to 2013. This topic was chosen due to the fact that there are no real quantifiable values of emission statistics from airlines available to the public. Further investigation allowed for Southwest Airlines to be compared to the overall Carbon Dioxide and Nitrous Oxide contributions of the United States for the year 2011. The results showed that with the absence of any set standard on emissions, it is vital that one should be established. The data showed that the current ICAO standard emission values showed a higher level of emissions than when Southwest Airline's fleet was analyzed using their actual fleet mix.

RELEVANCE OF PROCESS RISK ASSESSMENT IN AIRLINES

Directory of Open Access Journals (Sweden)

Oksana G. Feoktistova

2017-01-01

Full Text Available The notion of “the concept on assumed risk” that took over from the outdated concept of absolute security is analyzed, the increasing significance of operating risk assessment at the present stage is noted. Some basic risk assessment techniques are considered. Matrix technique of risk assessment is considered more thoroughly, and it may be used in risk assessment of airlines in the context of labour protection management system.The ability to correctly assess risks and develop appropriate precautionary measures will allow airlines to avoid incidents leading to drastic consequences for staff, as well as to direct and indirect costs for the enterprise among which there could be singled out both direct property damage and loss of profit and expenses connected to incident investigation, penalty and compensation payment, loss of business reputation and so on. To reduce the rate of accidents and to develop safe activities skills for airlines staff a risk assessment chart is supposed to be implemented, which will be an efficient accidents prevention involving the staff in the process and making them follow safe working conditions.Process risk assessment is an integral part of assessment of the whole enterprise activity and work efficiency of a department and particular workers evaluation system. Labour protection activity should be based on risk identification and its control. Risk assessment is a keystone of labour protection activity planning.

An Airline-Based Multilevel Analysis of Airfare Elasticity for Passenger Demand

Science.gov (United States)

Castelli, Lorenzo; Ukovich, Walter; Pesenti, Raffaele

2003-01-01

Price elasticity of passenger demand for a specific airline is estimated. The main drivers affecting passenger demand for air transportation are identified. First, an Ordinary Least Squares regression analysis is performed. Then, a multilevel analysis-based methodology to investigate the pattern of variation of price elasticity of demand among the various routes of the airline under study is proposed. The experienced daily passenger demands on each fare-class are grouped for each considered route. 9 routes were studied for the months of February and May in years from 1999 to 2002, and two fare-classes were defined (business and economy). The analysis has revealed that the airfare elasticity of passenger demand significantly varies among the different routes of the airline.

Burnus, M; Benner, V; Kirchner, D; Drabik, A; Stock, St

2012-03-01

Support programmes for stress reduction were offered independently in two departments (650 employees in total) of an insurance group. Both departments, referred to as comparison group 1 and 2 (CG1 and CG2), offered an Employee Assistance Programme (EAP) featuring individual consultations. The employees were addressed through different channels of communication, such as staff meetings, superiors and email. In CG1, a staff adviser additionally called on all employees at their workplace and showed them a brief relaxing technique in order to raise awareness of stress reduction. By contacting employees personally it was also intended to reduce the inhibition threshold for the following individual talks. In CG2 individual talks were done face-to-face, whereas CG1 used telephone counselling. By using the new access channel with an additional personal contact at the workplace, an above average percentage of employees in CG1 could be motivated to participate in the following talks. The rate of participants was five times as high as in CG1, with lower costs for the consultation in each case.

Airline experience with reliability-centered maintenance

International Nuclear Information System (INIS)

Matteson, T.D.

1985-01-01

Reliability-Centered Maintenance is a process for developing preventive maintenance programs. Its concepts evolved from the post WWII experience of the airline community. Its genesis was in a paper by F. Stanley Nowlan and Thomas D. Matteson of United Airlines for the American Institute of Aeronautics and Astronautics in 1967. Its first application was to the Boeing 747. It has subsequently been adopted by the FAA and the Department of Defense and applied to many new transport and military aircraft. Its objective is applicable and effective preventive maintenance and it has proven to be a highly effective replacement for the prior intuitive processes for selective preventive maintenance tasks. It focuses on system functions, functional failures, then dominant failure modes and effects. It then uses a decision tree to classify failure criticality and identify applicable and effective tasks. The result is a program focused on maintaining inherent safety and reliability at minimum cost. (orig.)

The effect of airline deregulation on automobile fatalities.

Science.gov (United States)

Bylow, L F; Savage, I

1991-10-01

This paper attempts to quantify the effects of airline deregulation in the United States on intercity automobile travel and consequently on the number of highway fatalities. A demand model is constructed for auto travel, which includes variables representing the price and availability of air service. A reduced form model of the airline market is then estimated. Finding that deregulation has decreased airfares and increased flights, it is estimated that auto travel has been reduced by 2.2% per year on average. Given assumptions on the characteristics of drivers switching modes and the types of roads they drove on, the number of automobile fatalities averted since 1978 is estimated to be in the range 200-300 per year.

An insight into airline dynamic pricing practices in emerging markets: Effects of low cost carriers' presence on routes from Belgrade 'Nikola Tesla' airport

Directory of Open Access Journals (Sweden)

Ivanov Nikola V.

2016-01-01

Full Text Available Dynamic pricing and revenue management in airline industry have been the subject of research for more than twenty years now. Building upon that massive body of research, in this paper we investigate actual dynamic pricing patterns in new and emerging markets. We specifically focus on the impact that recent entry of low cost carriers on a number of routes from Belgrade Nikola Tesla Airport might have had on pricing practices of legacy incumbents. Unlike with most of previous contributions in the field, we analyse the market characterised by relatively low frequencies and predominantly short-to-medium haul flights. In this paper, we observe and analyse pricing dynamics on two types of routes: routes where only legacy carriers operate and routes where legacy carriers face competition from low cost carriers. The effects of route competition on offered airline fares are estimated and conclusions derived.

PESTE Analysis of the Romanian National Passenger Airline

Full Text Available A PESTE analysis is a view over the external environment of a company, business or an economical sector, and it plays an important part in the resource management and in a future decision making process. PESTE analysis places emphasis on the impact of each factor. At international level, different structures, from the governmental ones to well-known companies and not only, choose to analyze the important factors that disturb the good functioning of these entities. In the sector of passengers and freight air transport, the majority of airline operators have chosen to investigate the external environment in which they operate by using analytical methods. For instance, we can mention SWOT and PESTE analysis of the leading low-cost Air Asia, Malaysia's second carrier, that wishes to enter the Australian aviation market, PESTE analysis of Air Arabia - a new company in the Gulf that intends to corner the market of well-known companies such as Emirates Airlines, Gulf Air and Air China. Air Arabia, in order to implement TMQ (Total Management Qualities, has used a PESTE study. In this respect, the approach to monitor the external environment of Tarom national airline is essential in the world economic crisis and globalization activities in the passengers transport, under the conditions of deregulation of the airspace.

Xu, Xin; Cui, Qiang

2017-01-01

This paper focuses on evaluating airline energy efficiency, which is firstly divided into four stages: Operations Stage, Fleet Maintenance Stage, Services Stage and Sales Stage. The new four-stage network structure of airline energy efficiency is a modification of existing models. A new approach, integrated with Network Epsilon-based Measure and Network Slacks-based Measure, is applied to assess the overall energy efficiency and divisional efficiency of 19 international airlines from 2008 to 2014. The influencing factors of airline energy efficiency are analyzed through the regression analysis. The results indicate the followings: 1. The integrated model can identify the benchmarking airlines in the overall system and stages. 2. Most airlines' energy efficiencies keep steady during the period, except for some sharply fluctuations. The efficiency decreases mainly centralized in the year 2008–2011, affected by the financial crisis in the USA. 3. The average age of fleet is positively correlated with the overall energy efficiency, and each divisional efficiency has different significant influencing factors. - Highlights: • An integrated approach with Network Epsilon-based Measure and Network Slacks-based Measure is developed. • 19 airlines' energy efficiencies are evaluated. • Garuda Indonesia has the highest overall energy efficiency.

Full Text Available Against a backdrop of continuing discussion on the challenges faced by the apparel industry in Sri Lanka, the human involvement is yet to be considered as a significant organizational element. Therefore this study empirically examined the impact of job satisfaction and employee education on employee efficiency in the apparel industry with reference to the Gampaha district. The study was aimed to examine the problem “Is there an impact of job satisfaction and employee education on employee efficiency?”This study was conducted from a randomly selected sample of 90 respondents from an Apparel organization by administrating a structured questionnaire, which consisted of 37 questions that featured a 6 point scale. The sample of the study only consisted of machine operators. For the purpose of analyzing both descriptive and dummy variables regression was used. Descriptive analysis was used to clarify the basic features of the sample. In order to examine the relationship employee efficiency has with job satisfaction and employee education, an ANOVA model was constructed. The constructed ANOVA model for the study is as follows. EF = â0+ â1D1 + â2D2 +â3D3 + U The findings of the research revealed that there was no positive relationship between employee efficiency, job satisfaction and education and it was statistically confirmed by rejecting the two hypotheses. According to the study, the researcher observed that employee efficiency neither relates to employee job satisfaction nor the level of education of employees since they work to achieve their day to day targets.

Improving the United States airline industry's capacity to provide safe and dignified services to travelers with disabilities: focus group findings.

Science.gov (United States)

McCarthy, Michael J

2011-01-01

As a component of a training development project for intercity air travel providers, we investigated the capacity of the airline industry to meet the needs of travelers with disabilities by exploring: (1) the level of sensitivity among personnel to travelers' needs, (2) training currently provided, (3) areas in which additional training might be beneficial, and (4) organisational/systems-level commitment to dignified assistance to all travelers. Forty-four airline/vendor employees participated in nine focus groups in four US cities. Groups were audio recorded and transcribed. A grounded-theory approach was used to develop a coding system which was then applied to transcripts to identify themes. Factors influencing capacity grouped broadly into four areas: characteristics of the job/system, characteristics of current training, characteristics of providers themselves, and characteristics of travelers. At an interpersonal level, providers were empathetic and desired to provide dignified services. They lacked training and adequate equipment in some cases, however, and organisational commitment varied between companies. Traveler characteristics were also shown to impact service delivery. Results are promising but additional regulatory and organisational policies are needed to ensure quality services. Providers and consumers of intercity air travel services may benefit from the findings and recommendations of this study.

American Consumer’s Attitudes towards Different Airline Companies Channels: A Comparison of transaction Methods

Directory of Open Access Journals (Sweden)

Talha Harcar

2012-03-01

Full Text Available Consumers are increasingly challenging better performance from companies, and these demands are being met through improvements in technology and flexibility of services. As a result of recent progresses and developments in electronic marketing, the physical locations of brick and mortar businesses have become less significant since transactions can now be accomplished in cyberspace. In this paper, consumer attitudes towards online transactions for the airline industry are examined. Despite the growing acceptance of alternative delivery channels, the travel agencies remain an essential part of the customer-airline company. It can be argued that the travel agencies not only represent an opportunity for implementing costumer relationship, but they also remain an important point of contact for sales, service, and consultative interactions. Data has been analyzed using factor analysis technique. The study presents a broad picture of the level of preference of airline customers among the available distribution channels and sheds light on how airline companies should allocate resources among the different channels. The empirical study findings indicate that online transactions for the airline industry will gain in importance and its use will accelerate at a faster rate in the coming years.

Microorganisms that exist in aircraft air systems are considered to be the primary source of microbial contamination that can lead to illness shortly after flying. More than 600 million passengers board commercial airline flights annually in the United States alone. In this study, culture-independent, biomarker-targeted bacterial enumeration and identification strategies were used to estimate total bacterial burden and diversity within the cabin air of commercial airliners. Air-impingement was used to collect samples of microorganisms from 4 flights on 2 commercial carriers. The total viable microbial population ranged from below detection limits to 4.1 x 10{sup 6} cells/m{sup 3} of air. Microbes were found to gradually accumulate from the time of passenger boarding through mid-flight. A sharp decline in bacterial abundance was then observed. Representatives of the {alpha}, {beta} and {gamma} Proteobacteria, as well as Gram-positive bacteria, were isolated in varying abundance. Airline A had large abundances of Neisseria meningitidis rRNA gene sequences and Streptococcus oralis/mitis sequences. Airline B was dominated by pseudomonas synxantha sequences as well as N. meningitidis and S. oralis/mitis. The cabin air samples housed low bacterial diversity and were typically dominated by a particular subset of bacteria, notably opportunistic pathogenic inhabitants of the human respiratory tract and oral cavity. The microbes were found largely around the ventilation ducts and gasper conduits that supply cabin air. 45 refs., 4 tabs., 3 figs.

Formulation and demonstration of a robust mean variance optimization approach for concurrent airline network and aircraft design

Science.gov (United States)

Davendralingam, Navindran

Conceptual design of aircraft and the airline network (routes) on which aircraft fly on are inextricably linked to passenger driven demand. Many factors influence passenger demand for various Origin-Destination (O-D) city pairs including demographics, geographic location, seasonality, socio-economic factors and naturally, the operations of directly competing airlines. The expansion of airline operations involves the identificaion of appropriate aircraft to meet projected future demand. The decisions made in incorporating and subsequently allocating these new aircraft to serve air travel demand affects the inherent risk and profit potential as predicted through the airline revenue management systems. Competition between airlines then translates to latent passenger observations of the routes served between OD pairs and ticket pricing---this in effect reflexively drives future states of demand. This thesis addresses the integrated nature of aircraft design, airline operations and passenger demand, in order to maximize future expected profits as new aircraft are brought into service. The goal of this research is to develop an approach that utilizes aircraft design, airline network design and passenger demand as a unified framework to provide better integrated design solutions in order to maximize expexted profits of an airline. This is investigated through two approaches. The first is a static model that poses the concurrent engineering paradigm above as an investment portfolio problem. Modern financial portfolio optimization techniques are used to leverage risk of serving future projected demand using a 'yet to be introduced' aircraft against potentially generated future profits. Robust optimization methodologies are incorporated to mitigate model sensitivity and address estimation risks associated with such optimization techniques. The second extends the portfolio approach to include dynamic effects of an airline's operations. A dynamic programming approach is

The Role of Consumer Experiences in Building the image of brands: A Study in Airlines

Directory of Open Access Journals (Sweden)

Ana Iris Tomás Vasconcelos

2015-04-01

Full Text Available Studies on brand and consumer experience gained emphasis from the twentieth century, however the relationship between these themes still has gaps. Therefore, this study examines the role of consumer experiences in building the brand image through the identification of thoughts, feelings and actions arising from consumer experiences with airlines, and the types of associations that the consumer makes such marks. Therefore, a variation of qualitative critical incident technique was used, considering those remembered experiences that have excelled in consumer perception, interviewing ten users of air services, based on a two parts semi-structured form: description of experiences with airlines and information about the image of the brands of airlines. The analyzed data have revealed that thoughts, feelings and actions arising from consumer experiences become important elements in shaping the perception of brands of airlines. Through the consumption experience, consumers mainly use the service attributes to build their perception of the marks of the airlines. These attributes are used either directly as to support other types of associations such as those related to company size.

Neck pain is considered to be a major health problem in modern societies. Many previous studies found that certain occupations are related to this problem or are associated with the risk of developing it in future. Although the pain is caused by mechanical factors, it may progress to a serious problem and give rise to other abnormal symptoms such as vertigo, headache, or migraine. To investigate the prevalence of neck pain among the cabin crew of Saudi Airlines. A cross-sectional study was carried out on the available Saudi Airlines cabin crews in King Fahad Airport during our visits, using questionnaires and measurements of several parameters. Neck Pain Questionnaires were distributed to the cabin crews on Saudi Airlines and assessment sheets were completed by all participants of the study to evaluate the prevalence and distribution of neck pain. Physical therapy examination of neck motions in different directions and specific tests were performed by all the participants to identify any symptoms. Using these data the prevalence of neck pain among the cabin crews was calculated. Collected data were analyzed statistically using SPSS software calculating the mean, median, and score of the questionnaire. According to the scoring system of the study, 31 (30.09%) of 105 cabin crew staff of Saudi Airlines had neck pain. Our study confirmed a positive correlation between this occupation and neck pain, and in fact found that according to the results of logistic regression analysis, this occupation is the only significant factor that affects the positive compression test. The prevalence of neck pain among the cabin crews of Saudi Airlines was emphasized. The results show a high prevalence of neck pain in the participants of the study, with most cases appearing to run a chronic - episodic course. Further research is needed to help us understand more about the long-term course of neck pain and its broader outcomes and impacts.

Full Text Available ABSTRACT OBJECTIVE Tto identify factors associated with unintentional sleep at work of airline pilots. METHODS This is a cross-sectional epidemiological study conducted with 1,235 Brazilian airline pilots, who work national or international flights. Data collection has been performed online. We carried out a bivariate and multiple logistic regression analysis, having as dependent variable unintentional sleep at work. The independent variables were related to biodemographic data, characteristics of the work, lifestyle, and aspects of sleep. RESULTS The prevalence of unintentional sleep while flying the airplane was 57.8%. The factors associated with unintentional sleep at work were: flying for more than 65 hours a month, frequent technical delays, greater need for recovery after work, work ability below optimal, insufficient sleep, and excessive sleepiness. CONCLUSIONS The occurrence of unintentional sleep at work of airline pilots is associated with factors related to the organization of the work and health.

Fuzzy-VIKOR analysis for customer performance index of civil domestic airline industry in India

Directory of Open Access Journals (Sweden)

Suman Saket

2015-03-01

Full Text Available This paper considers the factor influencing on an airline carrier based on operations of an airport on the routes flown out of that airport. This study deals with evaluation of the Customer Performance index (CPI of distinct domestic civil airlines in India. CPI consists of various parameters; among them many disembodied parameters, which are difficult to measure. In this context, initially we identified the prime factors that are crucial for evaluation of performances provided by various airlines in India. Thereafter, in order to determine the hierarchy among these factors; modified digital logic (MDL approach is employed and cost is found to be the most important criteria. Furthermore, CPI is calculated using fuzzy-VIKOR approach. Such approaches can help the airlines in re-evaluating their current policies and then formulate comparatively more efficient market strategies to improve performance quality and to gain customers’ loyalty.

Complaints as starting point for vicious cycles in customer–employee-interactions

Science.gov (United States)

Traut-Mattausch, Eva; Wagner, Sara; Pollatos, Olga; Jonas, Eva

2015-01-01

A ring-model of vicious cycles in customer–employee-interaction is proposed: service employees perceive complaints as a threat to their self-esteem resulting in defense responses such as an increased need for cognitive closure, a devaluation of the customer and their information and degrading service behavior. Confronted with such degrading service behavior, customers react defensively as well, by devaluing the employee for example with regard to his/her competence and by reducing repurchase and positive word-of-mouth (WOM). Three studies investigated each link in this ring-model. In study 1, participants were confronted with an aggressive or neutral customer complaint. Results show that motivated closed-mindedness (one aspect of the need for cognitive closure) increases after an aggressive complaint leading to a devaluation of the customer and their information, and in turn to a degrading service reaction. In study 2, participants were confronted with a degrading or favorable service reaction. Results show that they devaluate the employees’ competence after receiving a degrading service reaction and thus reduce their intention to repurchase. In study 3, we finally examined our predictions investigating real customer–employee-interactions: we analyzed data from an evaluation study in which mystery callers tested the service hotline of an airline. Results show that the employees’ competence is devaluated after degrading behavior and thus reduces positive WOM. PMID:26528194

Full Text Available In the face of numerous challenges that organisations encounter they cannot survive independently of the industry in which they operate. Constant interaction with industry role players and the ability to adapt and align organisational strategies to changes within the industry are instrumental to improved profitability. This study aimed to better understand the impact that industry role players have on their profitability and competitiveness in a volatile environment. Such an appreciation will assist organisations to continuously adapt their strategies to industry variations. The airline industry was selected because of its volatility that has seen a decline in the profitability of airlines operating worldwide; and Air Zimbabwe in particular because of the extreme macro and micro environmental forces under which it operates. Zimbabwean aviation industry employees' in current employ at Air Zimbabwe, employed by foreign airlines, travel agents, ground handling agents and aviation regulators were interviewed. The impact on competitiveness and profitability of six major industry role players (competitor airlines, suppliers, buyers, substitute products, new entrants and regulatory authorities in the airline industry was analysed. There was general consensus among respondents that industry role players strongly impact on both the profitability and competitiveness.

EXPLORING THE ROLE OF ALLIANCES, AGREEMENTS AND PARTNERSHIPS IN THE AIRLINE INDUSTRY; THE CASE OF APG NETWORK WITHIN THE ROMANIAN MARKET

Directory of Open Access Journals (Sweden)

CAMELIA MONICA GHEORGHE

2017-08-01

Full Text Available During the last years, the airline industry had a dynamic evolution, due to significant changes such as: the liberalization of air traffic with two important consequences, the development of the hub and spoke model, as well as the emergence of low-cost companies; the commercialization and privatization of airports; the evolution of technology. In order to be competitive in this new context, taking part of an alliance or network, creating a partnership or an agreement became a key strategy for airlines and as well as other stakeholders involved. This article examines the different partnerships in the airline industry, starting from code-share agreements between airlines or the emergence of airline alliances as a consequence of the hub and spoke system up to the more recent airline-airports partnerships, code-share agreements involving low-cost companies or airline representation agreements for several (new markets. The case study of APG Network will be examined, in order to emphasize the role of GSAs (General Sales Agents in the development strategy of airlines. Moreover, a questionnaire was distributed among travel agencies and airlines operating in Romania, to identify their perception on APG and its impact on the Romanian market.

Both culture-based and culture-independent, biomarker-targeted microbial enumeration and identification technologies were employed to estimate total microbial and viral burden and diversity within the cabin air of commercial airliners. Samples from each of twenty flights spanning three commercial carriers were collected via air-impingement. When the total viable microbial population was estimated by assaying relative concentrations of the universal energy carrier ATP, values ranged from below detection limits (BDL) to 4.1 x 106 cells/cubic m of air. The total viable microbial population was extremely low in both of Airline A (approximately 10% samples) and C (approximately 18% samples) compared to the samples collected aboard flights on Airline A and B (approximately 70% samples). When samples were collected as a function of time over the course of flights, a gradual accumulation of microbes was observed from the time of passenger boarding through mid-flight, followed by a sharp decline in microbial abundance and viability from the initiation of descent through landing. It is concluded in this study that only 10% of the viable microbes of the cabin air were cultivable and suggested a need to employ state-of-the art molecular assay that measures both cultivable and viable-but-non-cultivable microbes. Among the cultivable bacteria, colonies of Acinetobacter sp. were by far the most profuse in Phase I, and Gram-positive bacteria of the genera Staphylococcus and Bacillus were the most abundant during Phase II. The isolation of the human pathogens Acinetobacter johnsonii, A. calcoaceticus, Janibacter melonis, Microbacterium trichotecenolyticum, Massilia timonae, Staphylococcus saprophyticus, Corynebacterium lipophiloflavum is concerning, as these bacteria can cause meningitis, septicemia, and a handful of sometimes fatal diseases and infections. Molecular microbial community analyses exhibited presence of the alpha-, beta-, gamma-, and delta- proteobacteria, as well as

2016-12-01

Full Text Available The long-term survival and competiveness of the airline business is strongly connected to the quality of service offered by airline operators and their ability to satisfy and build long-term relationships with customers. This study investigates the relationship among service quality, customer satisfaction and loyalty in the Nigerian airline industry. The cross-sectional survey research design was chosen in order to collect the primary data, using a structured questionnaire. Convenience sampling was adopted to draw a sample of 800 respondents. The data collected were analysed using correlation and multiple regression analysis. The findings of this study largely support the hypothesized relationships proposed in the conceptual framework. The results specifically reveal that perceived service quality is positively related to both passengers’ satisfaction and loyalty. The relationship between passenger satisfaction and loyalty towards the airlines was also found to be positive. The mediating effect of customer satisfaction between perceived service quality and customer loyalty is also found to be positive and partially supported. On the basis of the findings of this study, we conclude that perceived service quality does influence passenger satisfaction, and by extension, loyalty to the airlines. Thus, improvement of service quality is an adjuvant factor to sustainable differentiation and competitiveness in the airline industry. We therefore, recommend that airline operators develop and implement market-oriented service strategies to identify customers’ needs and expectations in order to serve them better. Additionally, airline operators should measure service quality regularly to assure that they are keep meeting passengers’ expectations, and consider customizing their products and services (as needed to enhance customer satisfaction and loyalty.

The Association of European Airlines (AEA) Perspective: The Operator Experience and Views

International Nuclear Information System (INIS)

Oksanen, P.J.

1999-01-01

The EU Council has adopted a Directive laying down the basic safety standards for the protection of aircrew exposed to cosmic radiation. As a result, carriers must determine which operations are likely to result in exposures exceeding 1 mSv, how to estimate the effective doses for individual crew members, inform the flight crews of possible health risks involved and ensure that the dose received by the foetus will not exceed 1 mSv following declaration of pregnancy. Members of the Association of European Airlines (AEA) welcome this initiative but emphasise the need for an harmonised approach. Over the years many AEA carriers have been involved in work on cosmic radiation in cooperation with the scientific community. They have measured and estimated doses on their network, made educational materials available to crew members, participated in epidemiological studies and collaborated with other interested parties. At present, AEA carriers are in the process of harmonising the advice given to all crew members together with the additional more specific information necessary for women. Many airlines are also participating in a major European epidemiological study. Finally, AEA airlines continue to be extensively involved in the measurement and estimation of cosmic radiation levels. The AEA airlines believe the EURATOM Directive may best be implemented by route dose estimation using a common mathematical model. This would have the advantage that modelling is accepted worldwide as a credible and practical method of dose estimates and overcomes the logistic problems, the likelihood of equipment failure and error inherent in direct measurement. In addition, it allows for consistency of route dose estimates among various airlines and finally offers the opportunity for independent scrutiny and audit as required. (author)

C Language Integrated Production System (CLIPS), a NASA-developed expert systems program, is used by American Airlines for three purposes: as a rapid prototyping tool; to develop production prototypes; and to develop production application. An example of the latter is CLIPS' use in "Hub S1AAshing," a knowledge based system that recommends contingency plans when severe schedule reductions must be made. Hub S1AAshing has replaced a manual, labor intensive process. It saves time and allows Operations Control Coordinators to handle more difficult situations. Because the system assimilates much of the information necessary to facilitate educated decision making, it minimizes negative impact in situations where it is impossible to operate all flights.

Strategies for improving employee retention.

Science.gov (United States)

Verlander, Edward G; Evans, Martin R

2007-03-28

This article proposes a solution to the perennial problem of talent retention in the clinical laboratory. It includes the presentation of 12 strategies that may be used to significantly improve institutional identity formation and establishment of the psychological contract that employees form with laboratory management. Identity formation and psychological contracting are deemed as essential in helping reduce employee turnover and increase retention. The 12 conversational strategies may be used as a set of best practices for all employees, but most importantly for new employees, and should be implemented at the critical moment when employees first join the laboratory. This time is referred to as "retention on-boarding"--the period of induction and laboratory orientation. Retention on-boarding involves a dialogue between employees and management that is focused on the psychological, practical, cultural, and political dimensions of the laboratory. It is placed in the context of the modern clinical laboratory, which is faced with employing and managing Generation X knowledge workers. Specific topics and broad content areas of those conversations are outlined.

2018-01-01

The 2015 Germanwings Flight 9525 disaster, in which 150 people were killed after the co-pilot may have intentionally crashed the plane in a suicide attempt, highlights the importance of better understanding the mental health of commercial airline pilots. However, there have been few systematic reviews investigating the topic of mental health in commercial aviation. This systematic review aims to identify the types and prevalence of mental health disorders that commercial airline pilots experience with a focus on mood disorders and suicide risk. A systematic literature search was performed using PubMed, EMBASE, and PsycINFO databases. Eligible studies were assessed and data was extracted and analyzed. 20 studies were identified. The prevalence of depression experienced by commercial airline pilots in this review ranged from 1.9% to 12.6%. Factors that negatively impacted the mental health of pilots included substance abuse, experiencing verbal or sexual abuse, disruption in sleep circadian rhythms and fatigue. This systematic review identifies that commercial airline pilots may experience depression at least as frequently as the general population. Commercial airline pilots experience occupational stressors, such as disrupted circadian rhythms and fatigue which may increase risks of developing mood disorders. Most studies identified in this review were cross-sectional in nature with substantial limitations. There is a clear need for further higher quality longitudinal studies to better understand the mental health of commercial airline pilots.

Social Media has taken the world by surprise at a swift and commendable pace. With the advent of any kind of circumstances may it be related to social, political or current affairs the sentiments of people throughout the world are expressed through their help, making them suitable candidates for sentiment mining. Sentimental analysis becomes highly resourceful for any organization who wants to analyse and enhance their products and services. In the airline industries it is much easier to get feedback from astute data source such as Twitter, for conducting a sentiment analysis on their respective customers. The beneficial factors relating to twitter sentiment analysis cannot be impeded by the consumers who want to know the who’s who and what’s what in everyday life. In this paper we are classifying sentiment of Twitter messages by exhibiting results of a machine learning algorithm using R and Rapid Miner. The tweets are extracted and pre-processed and then categorizing them in neutral, negative and positive sentiments finally summarising the results as a whole. The Naive Bayes algorithm has been used for classifying the sentiments of recent tweets done on the different airlines.

Employee direct participation in organisational decisions and workplace safety.

Science.gov (United States)

Widerszal-Bazyl, Maria; Warszewska-Makuch, Magdalena

2008-01-01

Managers from 192 companies filled out the Employee Direct Participation in Organisational Change questionnaire measuring employees' direct participation (DP) in organisational decisions. Four main forms of DP were identified: individual and group consultations, and individual and group delegation. Workplace safety was measured with the number of accidents, the number of employees working in hazardous conditions, accident absenteeism and sickness absence. Results showed that the 2 latter indicators were significantly related to some parameters of DP. Thus, companies that used face-to-face individual consultation had lower accident absenteeism than ones that did not. The same effect was true for group consultation with temporary groups, and individual and group delegation. Workplaces with high scores for scope for group consultation had lower accident absenteeism, and those with high scores for scope for group delegation had lower sickness absence. It was concluded that employee DP had a positive influence on workplace safety, even if involvement was not directly related to safety.

Space weather effects and commerical airlines

Science.gov (United States)

Jones, J.; Bentley, R.; Hunter, R.; Taylor, G.; Thomas, D.

Space Weather (SW) phenomena can effect many areas of commercial airline operations including avionics, communications and GPS navigation systems. Of particular importance at present is the recently introduced EU legislation requiring the monitoring of aircrew radiation exposure, including any variations at aircraft altitudes due to solar activity. The Mullard Space Science Laboratory is collaborating with Virgin Atlantic Airways, the Civil Aviation Authority and the National Physical Laboratory on a 3- year project to monitor the levels of cosmic radiation on long-haul flights. The study will determine whether computer models currently used to predict radiation exposure of aircrew are adequate. It also aims to determine whether solar or geomagnetic activity can cause significant modifications to the doses. This presentation will begin by showing some of the preliminary results obtained so far. As an example, we present a comparison of flight doses measured following the 14t h July 2000 X - class flare that was accompanied by a major Solar Particle Event (SPE). The results highlight the importance of a range of external factors that can strongly influence how SPEs may effect the measured dose at aircraft altitudes. At present, any SPE contributions in the airlines' dose records can only be poorly estimated retrospectively. Ideally, it would be better to try to avoid operating during these possibly significant radiation - enhancing events by utilising SW information (alerts, warnings, etc.). However, doing so poses many difficult operational problems for such a heavily regulated international industry, in terms of safety, security and procedures. Therefore, the use of timely SW information, which is still very unreliable, in a similar manner to terrestrial weather will require agreement from the International Civil Aviation Organisation (ICAO) and International Air Transport Association (IATA) to Air Traffic Control and Aviation Regulatory Authority's.

Costs and Benefits of Stopping the Clock. How Airlines Profit from Changes in the EU ETS

Energy Technology Data Exchange (ETDEWEB)

Nelissen, D.; Faber, J.

2012-12-15

All flights arriving at or departing from EU airports have been included in the EU ETS from the beginning of 2012. Airlines have to surrender allowances for emissions on flights to and from EU airports. A share of the allowances has been issued to the airlines for free, the remainder needs to be acquired at an auction or from the market. In November 2012, the European Commission proposed to exempt intercontinental flights from the EU ETS for 2012, an initiative branded as 'Stopping the Clock'. As a result of this change, airlines on intercontinental routes are likely to experience additional windfall profit, since they have probably anticipated ETS-related expenditures on these routes, which they will now not incur. In addition, all airlines have a windfall profit since they are likely to pass on the value of the free allowances, as has been demonstrated to happen in all other sectors that have received free allowances. This note estimates the windfall profits. The report distinguishes two types of windfall profits: (1) Profits that occur because the opportunity costs of free allowances received for intercontinental flights have been passed on. These windfall profits would also have occurred without the 'stop the clock' exemption. We call them ETS Windfall. (2) Profits that occur because airlines have raised their revenues on intercontinental flights, but will not need to buy allowances either at the auction or from other actors because of the exemption. We call them Stopping the Clock Windfall. Depending on the cost pass through, the total windfall profits range from euro 679 million to euro 1,358 million. About a third of these windfall profits arise from the exemption of intercontinental flights. EU airlines are expected to reap the largest share of the windfall due to the change in regulation (55%), followed by US airlines (13%).

High Level Rule Modeling Language for Airline Crew Pairing

Science.gov (United States)

Mutlu, Erdal; Birbil, Ş. Ilker; Bülbül, Kerem; Yenigün, Hüsnü

2011-09-01

The crew pairing problem is an airline optimization problem where a set of least costly pairings (consecutive flights to be flown by a single crew) that covers every flight in a given flight network is sought. A pairing is defined by using a very complex set of feasibility rules imposed by international and national regulatory agencies, and also by the airline itself. The cost of a pairing is also defined by using complicated rules. When an optimization engine generates a sequence of flights from a given flight network, it has to check all these feasibility rules to ensure whether the sequence forms a valid pairing. Likewise, the engine needs to calculate the cost of the pairing by using certain rules. However, the rules used for checking the feasibility and calculating the costs are usually not static. Furthermore, the airline companies carry out what-if-type analyses through testing several alternate scenarios in each planning period. Therefore, embedding the implementation of feasibility checking and cost calculation rules into the source code of the optimization engine is not a practical approach. In this work, a high level language called ARUS is introduced for describing the feasibility and cost calculation rules. A compiler for ARUS is also implemented in this work to generate a dynamic link library to be used by crew pairing optimization engines.

Airplane cabin supply air has been shown to contain multiple possible respiratory irritants. In addition, changes in barometric pressure in flight may contribute to specific respiratory conditions. Therefore, there may be an association between commercial airline flight and sinus disease. Participants of the Secondhand-Smoke, Air Quality and Respiratory Health Among Flight Attendants Study were administered an online questionnaire pertaining to their flight experience and respiratory health. Working years, working days per month, and number of trips per month were quantified, as well as smoking exposure and self-reported physician diagnoses of sinusitis, asthma, and rhinitis. The sinonasal outcomes were quantified using a Respiratory Questionnaire Survey (RQS) score. Multivariable analyses were performed to evaluate the associations between flight time and sinus disease. A total of 579 participants met the inclusion criteria for this study, with cohort prevalence of sinusitis, asthma, and rhinitis of 25.3%, 14.4%, and 20.5%, respectively. Tertiles 2 and 3 of working days per month were associated with higher RQS scores compared to tertile 1 (p for trend <0.01). Individual symptoms significantly associated with increasing number of working days per month included "need to blow nose," "sneezing," and "thick nasal discharge," and the number of international trips per month was significantly associated with "coughing" and "facial pain and pressure," among other symptoms. This is the largest study to analyze the relations between airline flight time and sinonasal disease. The results suggest a possible association between sinusitis diagnosis, symptom scores, and specific sinonasal symptoms, and airline flight time. © 2016 ARS-AAOA, LLC.

An Examination of How Ratings of Airlines are Effected by Different Types of Information: A Mediation Analysis

Science.gov (United States)

Ozyurek, Abdullah Selim

Many dynamics directly or indirectly influence the decision-making process. An individual's demographic features, such as gender, country of origin, and emotions are some of the dynamics. In the aviation domain, air passengers purchase their air travel tickets under those dynamics. The purpose of this study was to determine if the airline type, gender of participants, and participants' country of origin had an effect on ratings of an individual's perception of safety and willingness to fly, and which emotions had a mediating effect on this relationship. The study included Lufthansa Airlines and Turkish Airlines from Europe. The affect was the participants' feeling outcomes of presented airline information. The feelings were Ekman and Friesen's (1971) universal emotions that include happiness, surprise, fear, disgust, anger, and sadness. The results of the study indicated that airline type, gender, and country of origin had a statistically significant effect and significant interaction on safety perception and willingness to fly. Also, emotions were found significant mediators on the mediation paths. Particularly happiness, fear, anger, and disgust emotions had a significant influence on participants' decision outcomes.

Directory of Open Access Journals (Sweden)

Douglas Karsner

2009-01-01

Full Text Available This article examines the transformation of transpacific tourism between the United States and Japan from 1947 to 1977, focusing on the key role that Pan American World Airways, Northwest Orient Airlines, and Japan Airlines played in this development. In the late 1940s, travel was mostly by a small upper class leisure market cruising on ships. Linkages between the air carriers and other factors, including governmental policy, travel organizations, and changes in business and culture influenced the industry. By the 1970s, these elements had reshaped the nature and geography of tourism, into a mass airline tourist market characterized by package tours, special interest trips, and consumer values.

Measurements of cosmic-ray doses in commercial airline cabins

International Nuclear Information System (INIS)

Okano, M.; Fujitaka, K.; Izumo, K.

1996-01-01

Cosmic radiation doses which aircrew and air passengers receive in airplanes have been calling attention in many countries especially in the last decade. In this relation, various types of information had been reported on cosmic radiation intensity. In Japan, the cosmic radiation intensity had been measured in commercial airline cabins as well as chartered flights. While the intensity depends on altitude, geomagnetic latitude (or cutoff rigidity), and temporal variation of the solar activity, their doses are often speculated based on paper records on airflights combined with the intensity-altitude relationship. In this study, however, efforts were made to estimate more realistic integrated doses in airline cabins based on actual on-board measurements which had been conducted several dozens of times in each year (e.g., 45 times in 1994 and 27 times in 1995).

Investigating brand personality of state-owned and private airlines: Maham Versus Iran Air

Directory of Open Access Journals (Sweden)

Mahdi Karoubi

2014-06-01

Full Text Available Today, companies need to create exclusion not in the market but in their own capabilities and features in order to gain distinction. The creation and maintenance of distinction through functional features is nearly impossible anymore. Thus, apart from the functional features, companies need to consider their intangible properties, among which brand is one of the most important ones. One of components researchers have detected for brand is personality, which can enhance the preference and loyalty of the customers and influence their decision process. In the service section, due to its specific features, the impacts of brand personality are more important and more complicated and airline companies, as service industries, which provide one of the most intangible products, are no exception. In the current study, using Aaker's Five-Dimension Model for brand personality, brand personality of a state-owned airline company (Iran Air and a private one (Mahan are compared from the perspective of technical directors of travel agencies. The population includes 233 technical directors whose views regarding brand personality of airline companies are studied following the distribution of questionnaires. The results of the data analysis indicate Mahan Airline is superior to Iran Air in all the five dimensions.

Recommendations to Improve Employee Thermal Comfort When Working in 40°F Refrigerated Cold Rooms.

Science.gov (United States)

Ceballos, Diana; Mead, Kenneth; Ramsey, Jessica

2015-01-01

Cold rooms are commonly used for food storage and preparation, and are usually kept around 40°F following food safety guidelines. Some food preparation employees may spend 8 or more hours inside cold rooms. These employees may not be aware of the risks associated with mildly cold temperatures, dampness, and limited ventilation. We performed an evaluation of cold rooms at an airline catering facility because of concerns with exposure to cold temperatures. We spoke with and observed employees in two cold rooms, reviewed daily temperature logs, evaluated employee's physical activity, work/rest schedule, and protective clothing. We measured temperature, percent relative humidity, and air velocities at different work stations inside the cold rooms. We concluded that thermal comfort concerns perceived by cold room employees may have been the result of air drafts at their workstations, insufficient use of personal protective equipment due to dexterity concerns, work practices, and lack of knowledge about good health and safety practices in cold rooms. These moderately cold work conditions with low air velocities are not well covered in current occupational health and safety guidelines, and wind chill calculations do not apply. We provide practical recommendations to improve thermal comfort of cold room employees. Engineering control recommendations include the redesigning of air deflectors and installing of suspended baffles. Administrative controls include the changing out of wet clothing, providing hand warmers outside of cold rooms, and educating employees on cold stress. We also recommended providing more options on personal protective equipment. However, there is a need for guidelines and educational materials tailored to employees in moderately cold environments to improve thermal comfort and minimize health and safety problems.

Full Text Available BASL Intimate Apparel Mirigama is the largest factory of Brandix Group of Companies catering to VS Pink. It has a labour force of 1250 employees including a direct labour force of 659. Production capabilities have been extended to in-house printing and embroidery sections in addition to cutting and shipping facilities. Like other apparel manufacturers in the industry, BASL Intimate Apparel Mirigama also faces much competition and problems in its day to day business operations. One of the major issues so faced is On-Time-Delivery due to underperformance of the employees. Therefore, with the objectives of studying factors affecting the underperformance of the employees of the production department, analysing and identifying such factors, and providing recommendations, a few variables i.e. machines and methods, skill level, financial incentives, leadership practices and working conditions were identified as having a potential impact over the performance of the production employees. Stratified random sampling method was used to select 64 team members from the 32 production modules, and research work continued to collate primary data through administrating a structured questionnaire among selected associates. Null and alternative hypotheses were tested using correlations, and the data is presented as graphical pictures, tables, and in narrative form. However, there were a few limitations such as management influence, sample basis selection, service period, level of understating, time availability and commitment, time availability for the study etc. which may have had an impact over the research findings.

Progress in airline distribution systems: The threat of new entrants to incumbent players

Directory of Open Access Journals (Sweden)

Athina Sismanidou

2009-07-01

Full Text Available For decades, distribution has been a key ICT (Information and Communication Technology area for airlines and this sector has been dominated by four (now three Global Distribution Systems (GDSs whose primacy has been threatened over the last four years by a set of new players, the so called GDS New Entrants (GNEs.  GNEs emerged with the advent of the Internet and open source technology as ‘disintermediation’ facilitators and generated vast interest from airlines because they promised to reduce the cost of distribution. This paper explores the impact of ICTs on airlines with a focus on GDSs. It provides an overview of the changing market dynamics, analyses the environment that led to the appearance of GNEs and pinpoints the issues behind their until now failure to provide a true alternative to the GDSs.  This analysis complements existing academic research in that it clarifies critical issues in the air travel distribution field and provides an overview of current industry developments.

AIRLINE ITINERARY CHOICE IN A DYNAMIC SUPPLY ENVIRONMENT: RESULTS FROM A STATED PREFERENCE SURVEY

Directory of Open Access Journals (Sweden)

Uzi Freund-Feinstei

2017-12-01

Full Text Available This paper investigates the choice of airline itineraries in dynamic settings using a tailored stated preference survey. The paper hypothesizes that airline itinerary choice is not a one-time event, but a continuous process during a certain time frame. Consumers can choose either to purchase an itinerary, deferring choice up to the end of the sales period, or completely declining the purchase. Understanding such consumers’ behavior is specifically relevant to the tourism industry, where firms are extensively utilizing internet websites to offer their products (e.g., airline tickets, hotel rooms to consumers. The paper describes the stated preference survey with real itineraries of various airlines on medium and long-haul routes. Choice sets are composed with dynamic and static variables and socio-economic variables. Questionnaires were distributed electronically among various groups of respondents, yielding a sample of 914 persons. Results show that (i itinerary choice deferring takes place, with differences between tourists and business-travelers, (ii the decision whether to defer choice is affected by dynamically changing variables and by the length of each respondent’s allocated choice period, and (iii the proposed methodology is adequate for investigating choice in dynamic settings and thus indicating its potential for further research in transportation planning and in tourism.

Attractiveness-Based Airline Network Models with Embedded Spill and Recapture

Directory of Open Access Journals (Sweden)

Desmond Di Wang

2014-01-01

Full Text Available Purpose: In airline revenue management, the modeling of the spill and recapture effects is essential for an accurate estimation of the passenger flow and the revenue in a flight network. However, as most current approaches toward spill and recapture involve either non-linearity or a tremendous amount of additional variables, it is computationally intractable to apply those techniques to the classical network design and capacity planning models.Design/methodology: We present a new framework that incorporates the spill and recapture effects, where the spill from an itinerary is recaptured by other itineraries based on their attractiveness. The presented framework distributes the accepted demand of an itinerary according to the currently available itineraries, without adding extra variables for the recaptured spill. Due to its compactness, we integrate the framework with the classical capacity planning and network design models.Findings: Our preliminary computational study shows an increase of 1.07% in profitability anda better utilization of the network capacity, on a medium-size North American airline provided by Sabre Airline Solutions.Originality/value: Our investigation leads to a holistic model that tackles the network design and capacity planning simultaneously with an accurate modeling of the spill and re- capture effects.Furthermore, the presented framework for spill and recapture is versatile and can be easily applied to other disciplines such as the hospitality industry and product line design (PLD problems.

2014-01-01

Aircraft passenger spaces designed without proper anthropometric analyses can create serious problems for obese passengers, including: possible denial of boarding, excessive body pressures and contact stresses, postural fixity and related health hazards, and increased risks of emergency evacuation failure. In order to help address the obese passenger's accommodation issues, this study developed male and female manikin families that represent obese US airline passengers. Anthropometric data of obese individuals obtained from the CAESAR anthropometric database were analyzed through PCA-based factor analyses. For each gender, a 99% enclosure cuboid was constructed, and a small set of manikins was defined on the basis of each enclosure cuboid. Digital human models (articulated human figures) representing the manikins were created using a human CAD software program. The manikin families were utilized to develop design recommendations for selected aircraft seat dimensions. The manikin families presented in this study would greatly facilitate anthropometrically accommodating large airline passengers.

Optimizing Air Transportation Service to Metroplex Airports. Par 2; Analysis Using the Airline Schedule Optimization Model (ASOM)

Science.gov (United States)

Donoue, George; Hoffman, Karla; Sherry, Lance; Ferguson, John; Kara, Abdul Qadar

2010-01-01

The air transportation system is a significant driver of the U.S. economy, providing safe, affordable, and rapid transportation. During the past three decades airspace and airport capacity has not grown in step with demand for air transportation; the failure to increase capacity at the same rate as the growth in demand results in unreliable service and systemic delay. This report describes the results of an analysis of airline strategic decision-making that affects geographic access, economic access, and airline finances, extending the analysis of these factors using historic data (from Part 1 of the report). The Airline Schedule Optimization Model (ASOM) was used to evaluate how exogenous factors (passenger demand, airline operating costs, and airport capacity limits) affect geographic access (markets-served, scheduled flights, aircraft size), economic access (airfares), airline finances (profit), and air transportation efficiency (aircraft size). This analysis captures the impact of the implementation of airport capacity limits, as well as the effect of increased hedged fuel prices, which serve as a proxy for increased costs per flight that might occur if auctions or congestion pricing are imposed; also incorporated are demand elasticity curves based on historical data that provide information about how passenger demand is affected by airfare changes.

2013-06-01

This study examined the prevalence of airline pilots who have an excessive cardiovascular disease (CVD) risk score according to the New Zealand Guideline Group (NZGG) Framingham-based Risk Chart and describes their cardiovascular risk assessment and investigations. A cross-sectional study was performed among 856 pilots employed in an Oceania based airline. Pilots with elevated CVD risk that had been previously evaluated at various times over the previous 19 yr were reviewed retrospectively from the airline's medical records, and the subsequent cardiovascular investigations were then described. There were 30 (3.5%) pilots who were found to have 5-yr CVD risk score of 10-15% or higher. Of the 29 pilots who had complete cardiac investigations data, 26 pilots underwent exercise electrocardiography (ECG), 2 pilots progressed directly to coronary angiograms and 1 pilot with abnormal echocardiogram was not examined further. Of the 26 pilots, 7 had positive or borderline exercise tests, all of whom subsequently had angiograms. One patient with a negative exercise test also had a coronary angiogram. Of the 9 patients who had coronary angiograms as a consequence of screening, 5 had significant disease that required treatment and 4 had either trivial disease or normal coronary arteries. The current approach to investigate excessive cardiovascular risk in pilots relies heavily on exercise electrocardiograms as a diagnostic test, and may not be optimal either to detect disease or to protect pilots from unnecessary invasive procedures. A more comprehensive and accurate cardiac investigation algorithm to assess excessive CVD risk in pilots is required.

2013-06-01

The purpose of this study was to measure the level of quality of work life (QWL) among hospital employees in Iran. Additionally, it aimed to identify the factors that are critical to employees' QWL. It also aimed to test a theoretical model of the relationship between employees' QWL and their intention to leave the organization. A survey study was conducted based on a sample of 608 hospital employees using a validated questionnaire. Face, content and construct validity were conducted on the survey instrument. Hospital employees reported low QWL. Employees were least satisfied with pay, benefits, job promotion, and management support. The most important predictor of QWL was management support, followed by job proud, job security and job stress. An inverse relationship was found between employees QWL and their turnover intention. This study empirically examined the relationships between employees' QWL and their turnover intention. Managers can take appropriate actions to improve employees' QWL and subsequently reduce employees' turnover.

Customers' attributional judgments towards complaint handling in airline service: a confirmatory study based on attribution theory.

Science.gov (United States)

Chiou, Wen-Bin

2007-06-01

Besides flight safety, complaint handling plays a crucial role in airline service. Based upon Kelley's attribution theory, in the present study customers' attributions were examined under different conditions of complaint handling by the airlines. There were 531 passengers (216 women; ages 21 to 63 years, M = 41.5, SD = 11.1) with experiences of customer complaints who were recruited while awaiting boarding. Participants received one hypothetical scenario of three attributional conditions about complaint handling and then reported their attributional judgments. The findings indicated that the passengers were most likely to attribute the company's complaint handling to unconditional compliance when the airline company reacted to customer complaints under low distinctiveness, high consistency, and when consensus among the airlines was low. On the other hand, most passengers attributed the company's complaint handling to conditional compliance under the conditions in which distinctiveness, consistency, and consensus were all high. The results provide further insights into how different policies of complaint management affect customers' attributions. Future directions and managerial implications are also discussed.

Competition and coordination in the U.S. airline hub-to-hub markets: An industry pre-merger case study

Directory of Open Access Journals (Sweden)

Prasun Bhattacharjee

2016-04-01

Full Text Available Purpose: This paper investigates the nature of conduct that existed in the U.S. airline hub-to-hub markets prior to the recent merger wave of the legacy carriers. We explore the strategic importance of network carrier hubs in form of “spheres of influence” on airline market conduct. We also simultaneously recognize the overgrowing role played by Low Cost Carriers (LCC over the years by estimating two conduct parameters - one in markets where LCCs directly compete head-to-head with legacy carriers and the other for markets which LCCs do not serve but has presence in the hub airports or adjacent airports comprising the market endpoints. Thus our supply side framework also sheds some light on the issue of perfect contestability in airline industry. Design/methodology/approach: We estimate a structural oligopoly model for differentiated products with competitive interactions using DB1B data for first quarter of 2004. Findings: Our results imply that the nature of competition is more aggressive relative to Bertrand behavior in hub-to-hub markets and that these markets are less than perfectly contestable. Originality/value: This paper adds to the empirical literature of airline competition by enabling estimation of the actual conduct parameter assuming firm price setting behavior in presence of product differentiation. Contrary to existing literature on airline competition, a structural model enables us to systematically separate out effects of demand, cost and strategic factors on observed airline prices.

Annualized TASAR Benefit Estimate for Alaska Airlines Operations

Science.gov (United States)

Henderson, Jeffrey

2015-01-01

The Traffic Aware Strategic Aircrew Request (TASAR) concept offers onboard automation for the purpose of advising the pilot of traffic compatible trajectory changes that would be beneficial to the flight. A fast-time simulation study was conducted to assess the benefits of TASAR to Alaska Airlines. The simulation compares historical trajectories without TASAR to trajectories developed with TASAR and evaluated by controllers against their objectives. It was estimated that between 8,000 and 12,000 gallons of fuel and 900 to 1,300 minutes could be saved annually per aircraft. These savings were applied fleet-wide to produce an estimated annual cost savings to Alaska Airlines in excess of $5 million due to fuel, maintenance, and depreciation cost savings. Switching to a more wind-optimal trajectory was found to be the use case that generated the highest benefits out of the three TASAR use cases analyzed. Alaska TASAR requests peaked at four to eight requests per hour in high-altitude Seattle center sectors south of Seattle-Tacoma airport.

Full Text Available Many organisations recognizes the use of human resource as a major influence to their success. And with today’s competitive environment, it is imperative for organisations to find ways to be more effective and efficient in utilizing their resources so as to improve their general performance. Hence, there is need to recruit and retain highly qualified and motivated employees in order to remain competitive in the unstable environment. This study evaluates the relationship between recruitment practices, employee motivation and their impact on organisational performance focusing on the Nigerian banking industry, with a view to investigating factors that motivate employees of Nigerian banks and the methods banks adopt to motivate their employees. The study also assesses recruitment and selection methods used by Nigerian banks to select effective employees. The study is a cross-sectional in time and the primary data collected from a conveniently selected sample of 60 employees each of the seven selected banks. Face-to-face survey and interview was carried out in order to achieve the research objectives and back up theoretical findings. Using correlation and thematic analysis, the results indicated that there was a strong positive relationship between employee motivation, recruitment practices and organisational performance. Findings from the analysis identified that bank employees are mostly extrinsically motivated; although intrinsic factors also motivate them, it is not as motivating as extrinsic factors. The banks also provide more of extrinsic motivators to increase the performance of their employees. The banks make use of various methods of employee selection, by dividing the methods into stages. In addition, recruiting is mostly undertaken through recruitment agencies or advert placements. The study provides future recommendations that banks in Nigeria should be firmer in their selection processes; this will allow them to identify unsuitable

Rethinking Human-Centered Computing: Finding the Customer and Negotiated Interactions at the Airport

Wales, Roxana; O'Neill, John; Mirmalek, Zara

2003-01-01

The breakdown in the air transportation system over the past several years raises an interesting question for researchers: How can we help improve the reliability of airline operations? In offering some answers to this question, we make a statement about Huuman-Centered Computing (HCC). First we offer the definition that HCC is a multi-disciplinary research and design methodology focused on supporting humans as they use technology by including cognitive and social systems, computational tools and the physical environment in the analysis of organizational systems. We suggest that a key element in understanding organizational systems is that there are external cognitive and social systems (customers) as well as internal cognitive and social systems (employees) and that they interact dynamically to impact the organization and its work. The design of human-centered intelligent systems must take this outside-inside dynamic into account. In the past, the design of intelligent systems has focused on supporting the work and improvisation requirements of employees but has often assumed that customer requirements are implicitly satisfied by employee requirements. Taking a customer-centric perspective provides a different lens for understanding this outside-inside dynamic, the work of the organization and the requirements of both customers and employees In this article we will: 1) Demonstrate how the use of ethnographic methods revealed the important outside-inside dynamic in an airline, specifically the consequential relationship between external customer requirements and perspectives and internal organizational processes and perspectives as they came together in a changing environment; 2) Describe how taking a customer centric perspective identifies places where the impact of the outside-inside dynamic is most critical and requires technology that can be adaptive; 3) Define and discuss the place of negotiated interactions in airline operations, identifying how these

Chiou, Wen-Bin; Chang, Ming-Hsu; Yang, Chao-Chin

2009-04-01

In the airline industry, membership and cabin class are noticeable servicescape features of customers' privilege status. Customers may learn that higher privilege customers are more desired and endured by the airline. From the customers' point of view, those with higher privilege may expect their demands to be complied with when they complain. The present study employed hypothetical scenarios to investigate how the privilege status of passengers and reasonability of their demands influenced their expectations toward the compliance of airline personnel. Analysis showed that higher privilege customers were more likely to expect airline personnel to comply with their demands. Moreover, participants with medium or high levels of privilege status had greater expectations of compliance even when demands were unreasonable. In sum, customer expectations toward complaint handling reflected predictions based on social learning.

2006-05-01

This study assessed the working and family life characteristics, and the degree of domestic and work strain of female workers with different employment statuses and weekly working hours who are rearing children. Participants were the mothers of preschoolers in a large Japanese city. We classified the women into three groups according to the hours they worked and their employment conditions. The three groups were: non-regular employees working less than 30 h a week (n=136); non-regular employees working 30 h or more per week (n=141); and regular employees working 30 h or more a week (n=184). We compared among the groups the subjective values of work, financial difficulties, childcare and housework burdens, psychological effects, and strains such as work and family strain, work-family conflict, and work dissatisfaction. Regular employees were more likely to report job pressures and inflexible work schedules and to experience more strain related to work and family than non-regular employees. Non-regular employees were more likely to be facing financial difficulties. In particular, non-regular employees working longer hours tended to encounter socioeconomic difficulties and often lacked support from family and friends. Female workers with children may have different social backgrounds and different stressors according to their working hours and work status.

Grounded for an ethical dilemma: disequilibrium in a commercial airline pilot.

Science.gov (United States)

Kirschen, Matthew P; Friedlander, Joel A

2012-10-01

This article presents the case of a 41-year-old airline pilot with benign paroxysmal positional vertigo who requests that his diagnosis not be disclosed to his commercial airline employer or his aviation medical examiner because it may result in the suspension of medical certification. The legal and ethical requirements for physicians reporting impaired pilots are discussed as well as practical recommendations for handling such situations. The argument is made that a physician's obligation to honor patient confidentiality should not take precedence over his or her duty to protect the safety and well-being of the airplane passengers and the general public. If the patient chooses not to self-report, a physician has an ethical obligation to report the patient's medical condition to the Federal Aviation Administration.

Goldman, Dana P; Leibowitz, Arleen A; Robalino, David A

2004-01-01

To determine the sensitivity of employees' health insurance decisions--including the decision to not choose health maintenance organization or fee-for-service coverage--during periods of rapidly escalating healthcare costs. A retrospective cohort study of employee plan choices at a single large firm with a "cafeteria-style" benefits plan wherein employees paid all the additional cost of purchasing more generous insurance. We modeled the probability that an employee would drop coverage or switch plans in response to employee premium increases using data from a single large US company with employees across 47 states during the 3-year period of 1989 through 1991, a time of large premium increases within and across plans. Premium increases induced substantial plan switching. Single employees were more likely to respond to premium increases by dropping coverage, whereas families tended to switch to another plan. Premium increases of 10% induced 7% of single employees to drop or severely cut back on coverage; 13% to switch to another plan; and 80% to remain in their existing plan. Similar figures for those with family coverage were 11%, 12%, and 77%, respectively. Simulation results that control for known covariates show similar increases. When faced with a dramatic increase in premiums--on the order of 20%--nearly one fifth of the single employees dropped coverage compared with 10% of those with family coverage. Employee coverage decisions are sensitive to rapidly increasing premiums, and single employees may be likely to drop coverage. This finding suggests that sustained premium increases could induce substantial increases in the number of uninsured individuals.

Larsen, Tulinda Deegan

In this study the researcher provides a behavioral framework for managing massive airline flight disruptions (MAFD) in the United States. Under conditions of MAFD, multiple flights are disrupted throughout the airline's route network, customer service is negatively affected, additional costs are created for airlines, and governments intervene. This study is different from other studies relating to MAFD that have focused on the operational, technical, economic, financial, and customer service impacts. The researcher argues that airlines could improve the management of events that led to MAFD by applying the principles of crisis management where the entire organization is mobilized, rather than one department, adapting organization development (OD) interventions to implement change and organization learning (OL) processes to create culture of innovation, resulting in sustainable improvement in customer service, cost reductions, and mitigation of government intervention. At the intersection of crisis management, OD, and OL, the researcher has developed a new conceptual framework that enhances the resiliency of individuals and organizations in responding to unexpected-yet-recurring crises (e.g., MAFD) that impact operations. The researcher has adapted and augmented Lalonde's framework for managing crises through OD interventions by including OL processes. The OD interventions, coupled with OL, provide a framework for airline leaders to manage more effectively events that result in MAFD with the goal of improving passenger satisfaction, reducing costs, and preventing further government intervention. Further research is warranted to apply this conceptual framework to unexpected-yet-recurring crises that affect operations in other industries.

Unfamiliar severe disruptions challenge Airline Operations Control professionals most, as their expertise is stretched to its limits. This study has elicited the structure of Airline Operations Control professionals' decision process during unfamiliar disruptions by mapping three macrocognitive activities on the decision ladder: sensemaking, option evaluation and action planning. The relationship between this structure and decision quality was measured. A simulated task was staged, based on which think-aloud protocols were obtained. Results show that the general decision process structure resembles the structure of experts working under routine conditions, in terms of the general structure of the macrocognitive activities, and the rule-based approach used to identify options and actions. Surprisingly, high quality of decision outcomes was found to relate to the use of rule-based strategies. This implies that successful professionals are capable of dealing with unfamiliar problems by reframing them into familiar ones, rather than to engage in knowledge-based processing. Practitioner Summary: We examined the macrocognitive structure of Airline Operations Control professionals' decision process during a simulated unfamiliar disruption in relation to decision quality. Results suggest that successful professionals are capable of dealing with unfamiliar problems by reframing them into familiar ones, rather than to engage in knowledge-based processing.

The consequences can be evident in stress and burnout in different symptoms. Thus, age-diverse employees are faced with different symptoms of burnout and stress when carrying out their work. The main aim of this paper is to present burnout of older employees compared to younger employees in Slovenian companies.

Job satisfaction and motivation: how do we inspire employees?

Productivity is defined as the efficient and effective use of resources with minimum waste and effort to achieve outcome. We live in a world that has limited resources. The health care industry faces this limitation more than any other industry. With these challenges facing health care administrators, the concept of productivity, job satisfaction and motivation become very important. Employee satisfaction and retention have always been an important issue for physicians, medical centers and businesses in general. Conventional human resources theories, developed some 50 years ago by Maslow and Herzberg, suggest that satisfied employees tend to be more productive, creative and committed to their employers. People are essential to productivity. The success of productivity improvement strategy is dependent on employee commitment, job satisfaction, skills, and motivation. Maslow's theory consists of a 5-level pyramid: physiologic or basic survival; physical and mental safety; sense of belonging; accomplishment, creativity, and growth; and self-actualization. Herzberg's theory suggests there are 2 groups of factors: hygiene (which satisfy) and motivation. The terms "job satisfaction" and "motivation" have, in my experience, become used interchangeably. There is a difference. Job satisfaction is an individual's emotional response to his or her current job condition, while motivation is the driving force to pursue and satisfy one's needs. Maslow and Herzberg's theories can be easily applied to the workplace. Managers can help employees achieve overall job satisfaction, which, with the employee's internal motivation drive, increase performance on the job.

Full Text Available Many time series with trend and seasonal pattern are successfully modeled and forecasted by the airline model of Box and Jenkins; however, this model neglects the presence of nonlinearity on data. In this paper, we propose a new nonlinear version of the airline model; for this, we replace the moving average linear component by a multilayer perceptron neural network. The proposedmodel is used for forecasting two benchmark time series; we found that theproposed model is able to forecast the time series with more accuracy that other traditional approaches.Muchas series de tiempo con tendencia y ciclos estacionales son exitosamente modeladas y pronosticadas usando el modelo airline de Box y Jenkins; sin embargo, la presencia de no linealidades en los datos son despreciadas por este modelo. En este artículo, se propone una nueva versión no lineal del modelo airline; para esto, se reemplaza la componente lineal de promedios móviles por un perceptrón multicapa. El modelo propuesto es usado para pronosticar dos series de tiempo benchmark; se encontró que el modelo propuesto es capaz de pronosticar las series de tiempo con mayor precisión que otras aproximaciones tradicionales.

Airline Overbooking Problem with Uncertain No-Shows

Directory of Open Access Journals (Sweden)

Chunxiao Zhang

2014-01-01

Full Text Available This paper considers an airline overbooking problem of a new single-leg flight with discount fare. Due to the absence of historical data of no-shows for a new flight, and various uncertain human behaviors or unexpected events which causes that a few passengers cannot board their aircraft on time, we fail to obtain the probability distribution of no-shows. In this case, the airlines have to invite some domain experts to provide belief degree of no-shows to estimate its distribution. However, human beings often overestimate unlikely events, which makes the variance of belief degree much greater than that of the frequency. If we still regard the belief degree as a subjective probability, the derived results will exceed our expectations. In order to deal with this uncertainty, the number of no-shows of new flight is assumed to be an uncertain variable in this paper. Given the chance constraint of social reputation, an overbooking model with discount fares is developed to maximize the profit rate based on uncertain programming theory. Finally, the analytic expression of the optimal booking limit is obtained through a numerical example, and the results of sensitivity analysis indicate that the optimal booking limit is affected by flight capacity, discount, confidence level, and parameters of the uncertainty distribution significantly.

Airline Sustainability Modeling: A New Framework with Application of Bayesian Structural Equation Modeling

Directory of Open Access Journals (Sweden)

Hashem Salarzadeh Jenatabadi

2016-11-01

Full Text Available There are many factors which could influence the sustainability of airlines. The main purpose of this study is to introduce a framework for a financial sustainability index and model it based on structural equation modeling (SEM with maximum likelihood and Bayesian predictors. The introduced framework includes economic performance, operational performance, cost performance, and financial performance. Based on both Bayesian SEM (Bayesian-SEM and Classical SEM (Classical-SEM, it was found that economic performance with both operational performance and cost performance are significantly related to the financial performance index. The four mathematical indices employed are root mean square error, coefficient of determination, mean absolute error, and mean absolute percentage error to compare the efficiency of Bayesian-SEM and Classical-SEM in predicting the airline financial performance. The outputs confirmed that the framework with Bayesian prediction delivered a good fit with the data, although the framework predicted with a Classical-SEM approach did not prepare a well-fitting model. The reasons for this discrepancy between Classical and Bayesian predictions, as well as the potential advantages and caveats with the application of Bayesian approach in airline sustainability studies, are debated.

Hospitality sector employees constitute one of the key groups with respect to their secondhand tobacco smoke exposure at work. This study aimed to detect urinary cotinine and breath carbon monoxide (CO) levels among bar and restaurant employees in Ankara, as well as the employees' opinions on the new antitobacco law, changes in smoking behavior, and subjective health status before and after the law entered into force. This before-after study was conducted in 19 premises, with the participation of 65 employees before implementation and 81 employees 3 months after implementation of the new antitobacco law in the hospitality sector. Data in both phases were collected through face-to-face surveys, breath CO measurements, and urinary cotinine analysis. Descriptive statistics were used to summarize data, whereas chi-square test, paired and unpaired t tests, and analysis of variance were used to compare groups. Most of the restaurant and bar employees were male and below 35 years old. Before-after comparison showed that health complaints of the hospitality sector employees such as watering and itching in the eyes, difficulty in breathing, and cough (p law. Among the smoking employees, mean number of cigarettes smoked was also found to decrease (p = .012). Majority of the employees (83.8%) were found to support the smoking ban in enclosed public places. Results of this study provide solid evidence on the positive health effects of smoke-free laws and employees' support for smoke-free workplaces.

The results of investigations of the neutron component (E=1-10 MeV) of cosmic radiation on board the 'Armenian Airlines' aircrafts using nuclear photoemulsion are presented. The emulsions were exposed on the flights from Yerevan to Moscow, St.-Petersburg, Beirut, Athens, Frankfurt, Amsterdam, Paris and Sofia, and on Concord supersonic flights from Paris to New York. The dependence of the neutron fluxes, and on absorbed and equivalent doses on the flight parameters were investigated. On the flights of the supersonic Concord, with an altitude of 17 km, the neutron fluxes were essentially higher in comparison to those measured on Armenian airliners. It is interesting to note, that the neutron flux and equivalent dose rate decrease with altitude up to 470 km in space, for example, on board the STS-57. The shape of the differential energy spectrum for fast neutrons is the same on all Armenian airlines flights, but significantly different at 17 km altitude, where the flux in the energy region above 3 MeV is increasing

Routine radiation monitoring has been carried out for more than 15 years aboard Air France airliners. Annual dose received by aircrews can be estimated in the 2-3 mSv range for subsonic long-haul aircrews. Recent dosimetric measurements, using CIRCE devices based on low-pressure TEPC microdosimetry techniques and by using new types of bubble damage detectors, seem to confirm partly these results. More investigations by these new techniques could be undertaken at other phases of the 11 year solar cycle. (author)

Comparison of airline passenger oxygen systems.

Science.gov (United States)

Byrne, N J

1995-08-01

The principal sources of oxygen for inflight passenger use, scheduled and unscheduled, are examined. Present practices of assessment of the passenger's "fitness to fly" are described. Three partner airlines, British Airways, U.S. Air, and Qantas, catering for more than 8000 oxygen requests annually, are compared. Analysis of customer use suggests that medical oxygen requests are frequently not clinically justified. The growth in demand, for both scheduled and unscheduled use of an expensive resource, supports the need for a "recommended best practice" among carriers. Passengers with respiratory disorders who will most benefit from inflight oxygen are vulnerable either to hypoxia or asthma.

Chen, Ching-Fu; Chen, Shu-Chuan

2012-07-01

The airline industry relies on the implementation of Safety Management System (SMS) to integrate safety policies and augment safety performance at both organizational and individual levels. Although there are various degrees of SMS implementation in practice, a comprehensive scale measuring the essential dimensions of SMS is still lacking. This paper thus aims to develop an SMS measurement scale from the perspective of aviation experts and airline managers to evaluate the performance of company's safety management system, by adopting Schwab's (1980) three-stage scale development procedure. The results reveal a five-factor structure consisting of 23 items. The five factors include documentation and commands, safety promotion and training, executive management commitment, emergency preparedness and response plan and safety management policy. The implications of this SMS evaluation scale for practitioners and future research are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

2016-09-01

Lower back pain (LBP) is the most common complaint worldwide and the leading cause of disability in the workplace. In Colombia there are no epidemiological data on low back pain in aviation. This study aimed to characterize lower back pain in pilots and maintenance technicians in a Colombian commercial airline. Information was collected from the total population in a Colombian commercial airline in Bogota during the period from 2011 to 2013 using a voluntary survey which requested demographics, occupational (LEST survey) factors, back pain, and chronic pain (chronic pain grade scale). The prevalence rate of LBP in pilot respondents was 71% and the factors associated previously have belonged to the military forces: occupational exposure to physical load and work time. Chronic low back pain was at a prevalence of 49%. The prevalence of LBP in maintenance technicians was 65%. Associated factors were again similar to military forces and included mental workload. Chronic pain had a prevalence of 65%. Factors associated with chronic low back pain were the technicians' time in office and physical load. The prevalence of lower back pain in pilots is similar to that presented in the airline world population. In the case of maintenance technicians, the prevalence was higher than those found in other similar groups, but very similar to prevalences presented in different business industries, including the transport sector.

Before the current Ebola epidemic in West Africa, there were few documented cases of symptomatic Ebola patients traveling by commercial airline, and no evidence of transmission to passengers or crew members during airline travel. In July 2014 two persons with confirmed Ebola virus infection who were infected early in the Nigeria outbreak traveled by commercial airline while symptomatic, involving a total of four flights (two international flights and two Nigeria domestic flights). It is not clear what symptoms either of these two passengers experienced during flight; however, one collapsed in the airport shortly after landing, and the other was documented to have fever, vomiting, and diarrhea on the day the flight arrived. Neither infected passenger transmitted Ebola to other passengers or crew on these flights. In October 2014, another airline passenger, a U.S. health care worker who had traveled domestically on two commercial flights, was confirmed to have Ebola virus infection. Given that the time of onset of symptoms was uncertain, an Ebola airline contact investigation in the United States was conducted. In total, follow-up was conducted for 268 contacts in nine states, including all 247 passengers from both flights, 12 flight crew members, eight cleaning crew members, and one federal airport worker (81 of these contacts were documented in a report published previously). All contacts were accounted for by state and local jurisdictions and followed until completion of their 21-day incubation periods. No secondary cases of Ebola were identified in this investigation, confirming that transmission of Ebola during commercial air travel did not occur.

2000-01-01

Full Text Available Even as World War Two hung in the balance, the United States looked to the postwar period as a time of opportunity for international airlines. However, U.S. officials disagreed over the best course of action for the future. Would they support one airline or competing carriers? Those favoring competition found a champion in Lowell Yerex, a New Zealand entrepreneur with a thriving Central American airline. However, his nominal British citizenship aroused concerns in an Anglophobic U.S. government, and thus it never accepted him as an option. Still, Yerex played a critical role in the development of U.S. policy and the maturation of modern commercial aviation.

An exact model for airline flight network optimization based on transport momentum and aircraft load factor

Directory of Open Access Journals (Sweden)

Daniel Jorge Caetano

2017-12-01

Full Text Available The problem of airline flight network optimization can be split into subproblems such as Schedule Generation (SG and Fleet Assignment (FA, solved in consecutive steps or in an integrated way, usually based on monetary costs and revenue forecasts. A linear pro­gramming model to solve SG and FA in an integrated way is presented, but with an al­ternative approach based on transport momentum and aircraft load factor. This alterna­tive approach relies on demand forecast and allows obtaining solutions considering min­imum average load factors. Results of the proposed model applications to instances of a regional Brazilian airline are presented. The comparison of the schedules generated by the proposed approach against those obtained by applying a model based on mone­tary costs and revenue forecasts demonstrates the validity of this alternative approach for airlines network planning.

The aim of this study was to evaluate the effects of an mHealth intervention (intervention using mobile technology) consisting of tailored advice regarding exposure to daylight, sleep, physical activity, and nutrition, and aiming to improve health-related behavior, thereby reducing sleep problems and fatigue and improving health perception of airline pilots. A randomized controlled trial was conducted among 502 airline pilots. The intervention group was given access to both the MORE Energy mobile application (app) with tailored advice and a website with background information. The control group was directed to a website with standard information about fatigue. Health-related behavior, fatigue, sleep, and health perception outcomes were measured through online questionnaires at baseline and at three and six months after baseline. The effectiveness of the intervention was determined using linear and Poisson mixed model analyses. After six months, compared to the control group, the intervention group showed a significant improvement on fatigue (β= -3.76, P<0.001), sleep quality (β= -0.59, P=0.007), strenuous physical activity (β=0.17, P=0.028), and snacking behavior (β= -0.81, P<0.001). No significant effects were found for other outcome measures. The MORE Energy mHealth intervention reduced self-reported fatigue compared to a minimal intervention. Some aspects of health-related behavior (physical activity and snacking behavior) and sleep (sleep quality) improved as well, but most did not. The results show offering tailored advice through an mHealth intervention is an effective means to support employees who have to cope with irregular flight schedules and circadian disruption. This kind of intervention might therefore also be beneficial for other working populations with irregular working hours.

The Presence of Behavioral Traps in U.S. Airline Accidents: A Qualitative Analysis

Directory of Open Access Journals (Sweden)

Jonathan Velazquez

2018-01-01

Full Text Available Behavioral traps are accident-inducing operational pitfalls aviators may encounter as a result of poor decision making. The Federal Aviation Administration (FAA identifies the existence of twelve of these negative pilot behaviors. These are: Peer Pressure; Get-There-Itis; Loss of Situational Awareness; Descent Below the Minimum En Route Altitude (MEA; Mind Set; Duck-Under Syndrome; Getting Behind the Aircraft; Continuing Visual Flight Rules (VFR into Instrument Conditions; Scud Running; Operating Without Adequate Fuel Reserves; Flying Outside the Envelope; and Neglect of Flight Planning, Preflight Inspections, and Checklists. The purpose of this paper was to study the nature of their occurrence in the airline domain. Four Subject Matter Experts (SMEs analyzed 34 National Transportation Safety Board (NTSB accident reports. The SMEs were able to identify many pilot actions that were representative of the behavioral traps. Behavioral traps were found in all accidents with Loss of Situational Awareness and Neglect of Flight Planning, Preflight Inspections, and Checklists dominant. Various themes began to emerge, which played important roles in many accidents. These themes included Crew Resource Management (CRM issues, airline management and fatigue. The findings of this study indicated that behavioral traps were prevalent in airline accidents including habitual noncompliance by pilots. Attitude management training is recommended.

Sherry, Lance; Ferguson, John; Hoffman, Karla; Donohue, George; Beradino, Frank

2012-01-01

This report describes the Airline Fleet, Route, and Schedule Optimization Model (AFRS-OM) that is designed to provide insights into airline decision-making with regards to markets served, schedule of flights on these markets, the type of aircraft assigned to each scheduled flight, load factors, airfares, and airline profits. The main inputs to the model are hedged fuel prices, airport capacity limits, and candidate markets. Embedded in the model are aircraft performance and associated cost factors, and willingness-to-pay (i.e. demand vs. airfare curves). Case studies demonstrate the application of the model for analysis of the effects of increased capacity and changes in operating costs (e.g. fuel prices). Although there are differences between airports (due to differences in the magnitude of travel demand and sensitivity to airfare), the system is more sensitive to changes in fuel prices than capacity. Further, the benefits of modernization in the form of increased capacity could be undermined by increases in hedged fuel prices

Full Text Available The debate concerning the interrelationships and effects between customer satisfaction and loyalty has been tossed back and forth, without a consensus opinion. This study examines the linkages between customer satisfaction and loyalty in Nigerian domestic airline industry. The study adopted correlation research design to elicit information via questionnaire from 600 domestic air passengers drawn through convenience sampling technique. The data obtained from the respondents were analysed with Pearson correlation analysis, linear regression, and One-way analysis of variance. Based on 383 completed data, the results provide support for the association and influence of customer satisfaction on customer loyalty. The study also found out that frequent air travelers displayed more loyalty tendency towards airline carriers compared to non-frequent air passengers. On the basis of aforementioned findings, the study concludes that customer satisfaction is extremely important in building and enhancing customer loyalty. Therefore, airline carriers should implement strategies that will guarantee long-term relationship with air travellers by offering service quality that will meet and exceeds their expectations and by extension customer satisfaction.

Safety leaders across industries face a critical challenge: engaging employees. While engagement of a few people may be easy in short-term projects, it is significantly more difficult with long-term processes. In this session we show leaders how they can create a culture where workers are more open and even eager to be involved in safety efforts. Our experience with safety leaders in the nuclear industry has verified that when the factors that drive organizational functioning are understood, leaders are enabled to augment employee engagement and attain significant improvement in safety outcomes. The underlying factors that influence employee engagement, performance, outcomes, and organizational culture are the same the world over. We will also show how safety is capable, by its intrinsic value, of winning profound support and direct engagement of employees. In this session, we will examine how leaders can leverage their decisions and actions to win over employees to safety and support them in their endeavors to promote it. Using the safety leadership best practices Vision, Credibility, Accountability, Communication, Collaboration, Action Orientation, and Recognition and Feedback, leaders increase their impact on their organization in favor of a culture that supports safety and employee engagement. Leaders that create a climate and culture where employee engagement thrives, realize better safety results. Leadership is not exclusively an inborn talent; it can be developed and enhanced. To this end, we will also show the advantages of transformational leadership style by comparing it to more classical transactional leadership

Full Text Available Civilian airline pilots have one of the most stressful occupations. The aim of this study was to identify the effect of work stressors and other factors on mental-emotional disturbances among airline pilots. A cross-sectional study was done by interviewing selected pilots of an airline using appropriate questionnaires, during their routine medical examination from May to July 1999 in Jakarta. Five aspects of work stressor were assessed: working conditions, physical conditions of working environment, career development, organization and interpersonal relationship. Mental-emotional disturbances were determined by using the Symptom Checklist 90 (SCL 90 questionnaire. Data analysis was carried out using relative risk by Cox regression with constant time. From 128 subjects interviewed, 109 could be analyzed. Most of the subjects were married (73.4% and college graduates (91.7%. The number of captains and first officers were almost equal. The prevalence of mental-emotional disturbances was 39.4%. Mental-emotional disturbances were significantly related to work stressors and moderately related to household tension (P = 0.184. Compared to pilots with low levels of work stressors, those with high or very high levels of work stressors had a risk of 4.6 times of mental-emotional disturbances [adjusted relative risk (RRa = 4.64; 95% confidence interval (CI = 1.01 – 19.65]. Adequate guides to cope work stressors and household tension which related to mental-emotional disturbance is recommended.

2012-05-01

Research purpose: To understand the challenges faced by the bank’s information technology leadership team to retain employees. Motivation for the study: To understand the challenges faced in attracting and retaining information technology professionals, and how this can serve as input for reducing skills shortages in Information Technology Divisions. Research design, approach and method: An interpretive approach employing a case study strategy and qualitative methods was employed. Semi structured interviews were conducted with thirteen senior managers and four directors of the bank’s Information Technology Division, who were selected on a purposive basis. Data were subjected to Creswell’s four stage data analysis process. Main findings: Findings indicate that employee turnover is the main contributor of skills shortages within the studied division. The lack of a retention strategy is making it difficult for leadership to identify crucial skills that must be retained. Practical/managerial implications: Evidence suggests that this bank, although they would like to retain information technology professionals, is not creating an environment conducive to do this, as little attention is paid to the unique demands of this group of employees. Contribution/value-add: This study investigates a specific group of employees for which a unique retention strategy does not exist. In understanding the challenges that impact on attracting and retaining information technology professionals, this study can contribute to the development of a retention strategy for these employees.

Collective efficacy in a high-fidelity simulation of an airline operations center

Science.gov (United States)

Jinkerson, Shanna

This study investigated the relationships between collective efficacy, teamwork, and team performance. Participants were placed into teams, where they worked together in a high-fidelity simulation of an airline operations center. Each individual was assigned a different role to represent different jobs within an airline (Flight Operations Coordinator, Crew Scheduling, Maintenance, Weather, Flight Scheduling, or Flight Planning.) Participants completed a total of three simulations with an After Action Review between each. Within this setting, both team performance and teamwork behaviors were shown to be positively related to expectations for subsequent performance (collective efficacy). Additionally, teamwork and collective efficacy were not shown to be concomitantly related to subsequent team performance. A chi-square test was used to evaluate existence of performance spirals, and they were not supported. The results of this study were likely impacted by lack of power, as well as a lack of consistency across the three simulations.

Effective decontamination is crucial if an airliner cabin is contaminated by biological contaminants, such as infectious disease viruses or intentionally released biological agents. This study used computational fluid dynamics (CFD) method as a tool and vaporized hydrogen peroxide (VHP) as an exemplary decontaminant and Geobacillus stearothermophilus spores as a simulant contaminant to investigate three VHP delivery methods for sterilizing two different airliner cabins. The CFD first determined the airflow and the transient distributions of the contaminant and decontaminant in cabins. Auxiliary equations were implemented into the CFD model for evaluating efficacy of the sterilization process. The improved CFD model was validated by the measured airflow and simulated contaminant distributions obtained from a cabin mockup and the measured efficacy data from the literature. The three decontaminant delivery methods were (1) to supply the mixed VHP and air through the environmental control system of a cabin, (2) to send mixed VHP and air through a front door and to extract them from a back door of a cabin, and (3) to send directly VHP to a cabin and enhance the mixing with air in the cabin by fans. The two air cabins studied were a single-aisle and a twin-aisle airliner one. The results show that the second decontaminant delivery method (displacement method) was the best because the VHP distributions in the cabins were most uniform, the sterilization time was moderate, and the corrosion risk was low. The method displaced the existing air by the air/disinfectant solution, rather than dispersive mixing as the other two methods. (author)

Applied Two-Class Overbooking Model in Thailand's Passenger Airline Data

Directory of Open Access Journals (Sweden)

Murati Somboon

2017-12-01

Full Text Available In this study, a mathematical model, which combines two of the most important airline revenue management strategies, namely overbooking and seat inventory control, is applied in Thailand's passenger airline data. Using this model, it is possible to find a closed-form solution for both the optimal booking limit and the optimal overbooking limit, simultaneously. Numerical study was set to evaluate the performance of the two-class overbooking model and to test three hypotheses using real-life data. Our two-class overbooking model outperformed the fixed-booking limit policy. Moreover, three hypotheses: the effect of varying the number of update booking limit points, the effect of an incorrect initial mean for demand, and the effect of a number of smoothing constants on an exponential smoothing method were tested using real-life data. At the 0.05 significance level, it was found that different numbers of update booking limit points affected profit, incorrect initial mean for demand did not affect profit when a high number of update booking limit points was set, and all of the smoothing constants in exponential smoothing method affected profit to some extent.

2017-06-01

Full Text Available The majority of workers have many occasional difficulties that sometimes become a problem affecting the worker’s performance. When this will repeatedly fail to meet expectations, a serious problem may become the main reason which contributes to the job decline. Therefore, a pattern of reduced performance indicates the need for a supervisory action from managers. Poor performance could be reflected under three main categories, such as employee availability, employee productivity, and employee conduct. The reasons and causes of this poor performance could be a personal issue related to the employee. Many types of personal problems are affecting the job performance in organizations, such as marital strife, financial difficulties and child care complication. More serious difficulties and the abuse of these problems-if not resolved-may cause unending issues at work. This problem is highly important especially that it can affect the job performance and the company income. Moreover, it can simply result in the failure of the employee to meet the performance standards, which kills productivity. The purpose of this qualitative exploratory phenomenological study is to clarify the management role in dealing with employees personal issues in the Lebanese organizations as perceived by the lived experience of managers. The research instrument which will be used is a face-to-face structured interview with six managers of the major functions in different Lebanese organizations. The sample type will be by convenience.

Held, B.J.; Cross, J.; Ellis, K.P.; Richards, C.P.; Rodriques, R.

1976-01-01

In August 1975, Lawrence Livermore Laboratory began to quantitatively fit all employees who are or may be required to wear any type of full-face respirator. After one year, 306 employees have been fitted. A total of 1362 tests were made, using seven makes of full-face respirators. Of the 306 employees fitted, 284 were tested using more than one make of full-face mask. All employees fitted could get a maximum use limit (MUL) of at least 100, 8 percent has a MUL of 100 to 499 on at least one of the makes of masks tested, 11 percent had an MUL of 500 to 999, 13 percent had an MUL of 1000 to 1999, 24 percent had an MUL of 2000 to 4999, and 44 percent had an MUL greater than 5000. These numbers were derived using the average of the peak leakages occurring during each of six exercises performed while wearing each mask. If the overall average leakage occurring during the six exercises rather than the peak average is used in the calculations, 90 percent of the employees could obtain an MUL over 1000 on at least one make of mask

2017-01-01

Occupational population-based epidemiological data relating to occupational contact allergies in the Chinese clothing industry are limited. To investigate the prevalence of occupational allergic contact dermatitis (OACD) and to identify the causative allergens among clothing employees in China, a cross-sectional study was conducted in 529 clothing employees at 12 clothing factories in Beijing. All employees were subjected to an interview using self-administered questionnaire and skin examination, and those who were diagnosed with occupational contact dermatitis (OCD) were patch tested. In the present survey, we found that the overall 1-year prevalence of OACD among the clothing employees was 8.5%. The 1-year prevalence of OACD among workers (10.8%) was significantly higher than that among managers (3.2%). The lesions were primarily on the hands and wrists in workers, but the face and neck in managers. The major allergens were nickel sulfate and cobalt dichloride in workers and colophony and p -tert-butylphenol formaldehyde resin in managers. In conclusion, workers are at a higher risk of OACD compared with managers in the Chinese clothing industry. In addition to hand dermatitis in workers, airborne contact dermatitis on the face and neck should be also addressed in managers.

These are just some examples of using facial recognition, because in modern society, detection and facial recognition tend to surround us everywhere. The aim of this article is to create an appli-cation for smartphones that can recognize human faces. The main goal of this application is to grant access to certain areas or rooms only to certain authorized persons. For example, we can speak here of hospitals or educational institutions where there are rooms where only certain employees can enter. Of course, this type of application can cover a wide range of uses, such as helping people suffering from Alzheimer's to recognize the people they loved, to fill gaps persons who can’t remember the names of their relatives or for example to automatically capture the face of our own children when they smile.

No studies have assessed the prevalence of fatigue, depression, sleepiness, and the risk of obstructive sleep apnea (OSA) among commercial airlines pilots in the Gulf Cooperation Council (GCC). This was a quantitative cross-sectional study conducted among pilots who were on active duty and had flown during the past 6 months for one of three commercial airline companies. We included participants with age between 20 and 65 years. Data were collected using a predesigned electronic questionnaire composed of questions related to demographic information in addition to the Fatigue Severity Scale (FSS), the Berlin Questionnaire, the Epworth Sleepiness Scale (ESS), and the Hospital Anxiety and Depression Scale (HADS). The study included 328 pilots with a mean age ± standard deviation of 41.4 ± 9.7 years. Overall, 224 (68.3%) pilots had an FSS score ≥ 36 indicating severe fatigue and 221 (67.4%) reported making mistakes in the cockpit because of fatigue. One hundred and twelve (34.1%) pilots had an ESS score ≥ 10 indicating excessive daytime sleepiness and 148 (45.1%) reported falling asleep at the controls at least once without previously agreeing with their colleagues. One hundred and thirteen (34.5%) pilots had an abnormal HADS depression score (≥ 8), and 96 (29.3%) pilots were at high risk for OSA requiring further assessment. Fatigue, sleepiness, risk of OSA, and depression are prevalent among GCC commercial airline pilots. Regular assessment by aviation authorities is needed to detect and treat these medical problems.

We conducted this study to characterize in-flight pediatric fatalities onboard commercial airline flights worldwide and identify patterns that would have been unnoticed through single case analysis of these relative rare events. Retrospective cohort study of pediatric in-flight medical emergencies resulting in fatalities between January 2010 and June 2013. A ground-based medical support center providing remote medical support to commercial airlines worldwide. Children (age 0-18 yr) who experienced a medical emergency resulting in death during a commercial airline flight. None. There were a total of 7,573 in-flight medical emergencies involving children reported to the ground-based medical support center, resulting in 10 deaths (0.13% of all pediatric in-flight emergencies). The median subject age was 3.5 months with 90% being younger than 2 years, the age until which children are allowed to travel sharing a seat with an adult passenger, also known as lap infants. Six patients had no previous medical history, with one suffering cardiorespiratory arrest after developing acute respiratory distress during flight and five found asystolic (including four lap infants). Four subjects had preflight medical conditions, including two children traveling for the purpose of accessing advanced medical care. Pediatric in-flight fatalities are rare, but death occurs most commonly in infants and in subjects with a preexisting medical condition. The number of fatalities involving seemingly previously healthy children under the age of 2 years (lap infants) is intriguing and could indicate a vulnerable population at increased risk of death related to in-flight environmental factors, sleeping arrangements, or yet another unrecognized factor.

Airline cabin crew are occupationally exposed to cosmic radiation and jet lag with potential disruption of circadian rhythms. This study assesses the influence of work-related factors in cancer incidence of cabin crew members. A cohort of 8,507 female and 1,559 male airline cabin attendants from Finland, Iceland, Norway and Sweden was followed for cancer incidence for a mean follow-up time of 23.6 years through the national cancer registries. Standardized incidence ratios (SIRs) were defined as ratios of observed and expected numbers of cases. A case-control study nested in the cohort (excluding Norway) was conducted to assess the relation between the estimated cumulative cosmic radiation dose and cumulative number of flights crossing six time zones (indicator of circadian disruption) and cancer risk. Analysis of breast cancer was adjusted for parity and age at first live birth. Among female cabin crew, a significantly increased incidence was observed for breast cancer [SIR 1.50, 95% confidence interval (95% CI) 1.32-1.69], leukemia (1.89, 95% CI 1.03-3.17) and skin melanoma (1.85, 95% CI 1.41-2.38). Among men, significant excesses in skin melanoma (3.00, 95% CI 1.78-4.74), nonmelanoma skin cancer (2.47, 95% CI 1.18-4.53), Kaposi sarcoma (86.0, 95% CI 41.2-158) and alcohol-related cancers (combined SIR 3.12, 95% CI 1.95-4.72) were found. This large study with complete follow-up and comprehensive cancer incidence data shows an increased incidence of several cancers, but according to the case-control analysis, excesses appear not to be related to the cosmic radiation or circadian disruptions from crossing multiple time zones.

To investigate the prevalence and risk factors of polypoid lesions of the gallbladder (PLGs) in petrochemical employees in Ningbo, Zhejiang Province, China. All active and retired employees aged 20-90 years (n = 11098) of a refinery and chemical plant in eastern China were requested to participate in a health survey. The participants were subjected to interview, physical examination, laboratory assessments and ultrasonography. All the participants were invited to have a physical examination after a face-to-face interview. Fasting blood samples were obtained from the antecubital vein, and the samples were used for the analysis of biochemical values. Abdominal ultrasonography was conducted. A total of 10461 (7331 men and 3130 women) current and former petrochemical employees attended for screening. The overall prevalence of post-cholecystectomy, gallstones and PLGs was 0.9%, 5.2% and 7.4%, respectively. Compared with the increased prevalence of either gallstones or post-cholecystectomy in older persons, PLGs were more common in the middle-aged, peaking in those aged 40-59 years. Excluding the patients with gallstones, gallstones mixed with PLGs, or those who had undergone cholecystectomy, in the remaining 9828 participants, the prevalence of PLGs in men (8.9%) was significantly higher than that in women (5.5%, P employees. Male gender, HBsAg positivity, and middle age are risk factors for developing PLGs.

Full Text Available Organizations have become more flexible, adaptable, with flat hierarchical structures, and a limited opportunity for promotion, and these will have a significant impact on jobs and individuals careers. Career is not only linked anymore to one organization, but to more, due to the movement of employees between organizations, which is no longer a problem. So, the organizations, due to ever-changing environment, are not always directly involved in their employees' career management, but in this article we will show that some organizations are still involved in managing careers by developing skills, knowledge, abilities, attitudes and behaviors, in order to obtain competitive advantage, performance, and attracting and retaining the best employees. We also show that, in the new Knowledge Economy, if they will learn more from their mistakes, and, if they will find out in advance what changes will take place in the economic environment, they will be able to face the changes and to overcome easier the obstacles, with the right employees and a solid stock of knowledge.

Paguntalan, John C; Gregoski, Mathew

2016-11-22

Worksite wellness programs offer an ideal setting to target high-risk sedentary workers to improve health status. Lack of physical activity is associated with increased risk for coronary heart disease and mortality. Despite the risks, the number of sedentary workers is increasing. This study examined the perceived barriers and motivators for physical activity among employees at high-risk for coronary heart disease. A purposive sample of 24 high-risk workers participating in a wellness program in rural South Carolina were enrolled in the study. Qualitative data was obtained through semi-structured face-to-face interviews. Grounded theory was used to analyze qualitative data, and identify overarching themes. Physical limitations due to pain and weakness, lack of motivation, and lack of time emerged as the main barriers to physical activity. Family relationships were reported as the strongest motivator along with social support and potential health benefits. Findings highlight the unique experience of high-risk workers with physical activity. The findingsunderscore the need to design and implement effective interventions specifically designed to meet the needs of high-risk employees.

To investigate the experiences and needs with respect to work participation of employees with rheumatoid arthritis (RA) treated with anti-tumour necrosis factor (TNF) therapy. Face-to-face interviews in 14 employees with RA on anti-TNF therapy focused on experiences, offered support and needs with respect to work participation. Experiences regarding work participation varied and ranged from fatigue at work, having no job control, not being understood by the work environment or difficulty dealing with emotions as a result of interaction within the work environment. Support by health care professionals for work participation was considered important, especially concerning social or psychological issues. Advice in becoming aware of one's changes in abilities was highly appreciated, as was the availability of professional advice in times of an urgent work issue due to RA. Employees mentioned an increase in social support at work and job control as important facilitating factors for work participation. Although patients with RA report improvement in their work functioning after starting anti-TNF therapy, employees continue facing challenges in working life due to RA. For support concerning work participation, it is recommended that health care professionals are more aware of work-related problems in patients with RA treated with anti-TNF therapy.

Full Text Available Sustainability is changing the competitive landscape and reshaping the opportunities and threats that companies face. However, for companies to become green they need employees to develop, believe and engage with these initiatives. To achieve success with sustainable practices, companies can use internal marketing which is based on the satisfaction of employees as a premise to achieve the retention and attraction of top talent that will lead to corporate success. It is estimated that the internal customer satisfaction and loyalty contribute to satisfying the external customers, leading ultimately to a company’s profit maximization. In this paper I explore the impact of companies’ sustainability efforts among their employees. More specifically, we examine the results of an online survey conducted on employees of 10 multinational companies regarding the implementation of green internal marketing and corporate social responsibility to enhance their satisfaction at work.

Evaluation of Improved Pushback Forecasts Derived from Airline Ground Operations Data

Carr, Francis; Theis, Georg; Feron, Eric; Clarke, John-Paul

2003-01-01

Accurate and timely predictions of airline pushbacks can potentially lead to improved performance of automated decision-support tools for airport surface traffic, thus reducing the variability and average duration of costly airline delays. One factor which affects the realization of these benefits is the level of uncertainty inherent in the turn processes. To characterize this inherent uncertainty, three techniques are developed for predicting time-to-go until pushback as a function of available ground-time; elapsed ground-time; and the status (not-started/in-progress/completed) of individual turn processes (cleaning, fueling, etc.). These techniques are tested against a large and detailed dataset covering approximately l0(exp 4) real-world turn operations obtained through collaboration with Deutsche Lufthansa AG. Even after the dataset is filtered to obtain a sample of turn operations with minimal uncertainty, the standard deviation of forecast error for all three techniques is lower-bounded away from zero, indicating that turn operations have a significant stochastic component. This lower-bound result shows that decision-support tools must be designed to incorporate robust mechanisms for coping with pushback demand stochasticity, rather than treating the pushback demand process as a known deterministic input.

2016-01-01

Face recognition is used to prove identity across a wide variety of settings. Despite this, research consistently shows that people are typically rather poor at matching faces to photos. Some professional groups, such as police and passport officers, have been shown to perform just as poorly as the general public on standard tests of face recognition. However, face recognition skills are subject to wide individual variation, with some people showing exceptional ability-a group that has come to be known as 'super-recognisers'. The Metropolitan Police Force (London) recruits 'super-recognisers' from within its ranks, for deployment on various identification tasks. Here we test four working super-recognisers from within this police force, and ask whether they are really able to perform at levels above control groups. We consistently find that the police 'super-recognisers' perform at well above normal levels on tests of unfamiliar and familiar face matching, with degraded as well as high quality images. Recruiting employees with high levels of skill in these areas, and allocating them to relevant tasks, is an efficient way to overcome some of the known difficulties associated with unfamiliar face recognition.

Ahmed Al Kuwaiti

2015-08-01

Full Text Available Employees are considered as an asset to any organization and each organization provide a better and flexible working environment to retain its best and resourceful workforce. As such continuous efforts are being taken to avoid or extend the exitwithdrawal of employees from the organization. Human resource managers are facing a challenge to predict the exit time of employees and there is no precise model existing at present in the literature. This study has been conducted to predict the probability of exit of an employee in an organization using appropriate statistical model. Accordingly authors designed a model using Additive Weibull distribution to predict the expected exit time of employee in an organization. In addition a Shock model approach is also executed to check how well the Additive Weibull distribution suits in an organization. The analytical results showed that when the inter-arrival time increases the expected time for the employees to exit also increases. This study concluded that Additive Weibull distribution can be considered as an alternative in the place of Shock model approach to predict the exit time of employee in an organization.

Norms and guidelines are formed for safe disposal of hospital waste but question is whether these guidelines are being followed and if so, to what extent. Hence, this study was conducted with objective to study the knowledge and practices about hospital waste disposal and universal safety precautions in class IV employee and to study its relationship with education, occupation and training. A cross-sectional study was carried out in a teaching hospital in Mumbai using semi-structured questionnaire in which Class IV employee were included. Questionnaire was filled by face to face interview. Data were analyzed using SPSS. 48.7% Class IV employee were not trained. More than 40% were following correct practices about disinfection of infectious waste. None of the respondents were using protective footwear while handling hospital waste. Only 25.5% were vaccinated for hepatitis B. 16% had done HIV testing due to contact with blood, body fluid, needle stick injury. Knowledge and practices about hospital waste disposal and universal precaution were statistically significant in trained respondents. Training of employees should be given top priority; those already in service should be given on the job training at the earliest.

2005-01-01

This paper examines the stock market s reaction to JetBlue s Initial Public Offering (1PO) and subsequent price movements of the stock. In particular, w e examine whether the euphoria surrounding JetBlue s IPO carried over to other firms in the sector by testing whether the shares of JetBlue s competitors showed a significant price reaction to JetBlue s IPO. JetBlue's IPO took place just a few months following September 11, 2001. These events resulted in dramatic changes in the airline industry and had significant implications on the economic gains of airlines. We examine JetBlue s accounting and stock performance and compare it to the relative performance of Southwest Airlines (SWA), a representative of the loa-cost carrier group. In addition, we compare both JetBlue's and SWA's financial condition and the relative performance of their stock to two mainline U S. carriers, Continental and Northwest. representatives of the conventional-cost carrier group. We analyze whether there are any performance differences among the low-cost carriers and between low-cost carriers and conventional-cost carriers. In particular, we examine whether low-cost carriers were able to sustain the economic impacts of 9/11 better than the conventional-cost carriers.

Full Text Available A government organisation in the water supply business was faced with the challenge of changing their traditional way of doing business to operate as a profit driven entity. This research focuses on how privatisation has affected front-line service employees. Both the front-line service employees and management were interviewed and included as cases to investigate changes that have occurred as a result of privatisation. These cases revealed that after privatisation front line service employees have received better training, appreciated a better system of communication, experienced a higher degree of empowerment and enjoyed an organisational culture that is more customer focused. The research, however, indicated lower levels of motivation, that employees do not appreciate an improvement in their reward system neither do they get feedback regarding their achievements and that they experience little job security.

To evaluate the My Health Matters! (MHM) program, a multifaceted workplace intervention relying on education and awareness, early detection and disease management with a focus on risk factors for metabolic syndrome. The MHM program was offered to 2,000 public servants working in more than 30 worksites in British Columbia, Canada. The MHM program included a health risk assessment combined with an opportunity to attend an on-site screening and face-to-face call back visits and related on-site educational programs. Clinical and economic outcomes were collected over time in this one-year prospective study coupled with administrative and survey data. Forty three per cent of employees (N=857) completed the online HRA and 23 per cent (N=447) attended the initial clinical visit with the nurse. Risk factors for metabolic syndrome were identified in more than half of those attending the clinical visit. The number of risk factors significantly decreased by 15 per cent over six months (N=141). The cost per employee completing the HRA was $205 while the cost per employee attending the initial clinical visit was $394. Eighty-two per cent of employees would recommend the program to other employers. This study supports that workplace interventions are feasible, sustainable and valued by employees. As such, this study provides a new framework for implementing and evaluating workplace interventions focussing on metabolic disorders.

Firms' contribution to the internal and external employability of older employees: evidence from Germany.

Science.gov (United States)

Tisch, Anita

2015-03-01

In the examination of older employees' employability, one can distinguish between internal and external employability. Internal employability can be measured by individual employment stability, and external employability occurs when employees replace one employment relationship with another. Most studies focus on the personal skills and characteristics that are necessary to maintain employability. However, external factors also contribute to individual employability. Therefore, this study examines which organisational attributes of firms contribute to older employees' employability in Germany. Taking firm and individual characteristics into account, the results of discrete-time survival models show that in specific organisational structures, older employees have higher internal employability. Accordingly, older employees are more likely to maintain employment in the service sector and in recruiting organisations facing (skilled) labour shortages. However, the results also indicate that financially investing organisations facilitate early labour market exits. With regard to older employees' external employability, the results show only little evidence indicating an association between organisational attributes of firms and the likelihood of job change.

Optimization Model and Algorithm Design for Airline Fleet Planning in a Multiairline Competitive Environment

Directory of Open Access Journals (Sweden)

Yu Wang

2015-01-01

Full Text Available This paper presents a multiobjective mathematical programming model to optimize airline fleet size and structure with consideration of several critical factors severely affecting the fleet planning process. The main purpose of this paper is to reveal how multiairline competitive behaviors impact airline fleet size and structure by enhancing the existing route-based fleet planning model with consideration of the interaction between market share and flight frequency and also by applying the concept of equilibrium optimum to design heuristic algorithm for solving the model. Through case study and comparison, the heuristic algorithm is proved to be effective. By using the algorithm presented in this paper, the fleet operational profit is significantly increased compared with the use of the existing route-based model. Sensitivity analysis suggests that the fleet size and structure are more sensitive to the increase of fare price than to the increase of passenger demand.

Employee suggestion programs: the rewards of involvement.

Mishra, J M; McKendall, M

Successful ESPs are the products of a great deal of effort by managers, administrators, teams, individuals, and reviewers, who are all striving to achieve the goals of increased profitability and enhanced employee involvement. A review of the literature indicates that there are several prescriptions that will increase the likelihood of a successful ESP (see the box). Today's American business prophets sound ceaseless calls to arms in the name of "world class performance," "global competitiveness," "total quality management," and a variety of other buzz terms. A burgeoning industry has evolved that promises, through speeches, teleconferences, seminars, and consulting contracts, to teach American organizations how to achieve excellence. In the face of a sputtering economy and unrelenting competitive pressure, today's managers must translate these laudatory ideals into hands-on reality without sacrificing the firm's profit margin to experimentation. If any idea can help an organization achieve improvement through a workable program, then that idea and that program deserve real consideration. An ESP represents an opportunity to tap the intelligence and resourcefulness of an organization's employees, and by doing so, reap significant cost savings. Those companies and managers that have an ESP program uniformly list economic advantages first when describing the benefits of their employee suggestion programs. But there is another deeper and longer term benefit inherent in an ESP. These programs allow employees to become involved in their organization; they drive deaccession to lower levels, they give employees more responsibility, they foster creative approaches to work, and they encourage creativity in pursuit of company goals.(ABSTRACT TRUNCATED AT 250 WORDS)

Manager-employee interaction in ambulance services: an exploratory study of employee perspectives on management communication.

Nordby, Halvor

2015-01-01

Managers of ambulance stations face many communicative challenges in their interaction with employees working in prehospital first-line services. The article presents an exploratory study of how paramedics experience these challenges in communication with station leaders. On the basis of a dialogue perspective in qualitative method, 24 paramedics were interviewed in one-to-one and focus group settings. Naturalistic and phenomenological approaches were used to analyze the interviews. All the paramedics said that they wished to be more involved in decision processes and that station managers should provide better explanations of information "from above." The paramedics understood that it was difficult for the managers to find time for extensive dialogue, but many thought that the managers should give more priority to communication. The paramedics' views correspond to theoretical assumptions in human resource management. According to this model, employees should be involved in decision processes on management levels, as long as it is realistically possible to do so. Furthermore, expressing emotional support and positive attitudes does not take much time, and the study suggests that many ambulance managers should focus more on interpersonal relations to employees. It has been extensively documented that management communication affects organizational performance. The study indicates that managers of ambulance stations should be more aware of how their leadership style affects professional commitment and motivation in the first-line services.

The efficiency of stunning cattle was assessed in 443 animals (304 pure Zebu and 139 crossbred cattle), being mainly mature bulls and cows. Cattle were stunned using a Jarvis pneumatically powered penetrating captive bolt gun operating with low (160-175psi, N=82) and high (190psi, N=363) airline pressure, which was within the manufactures specifications. Signs of brain function and the position of the shots on the heads were recorded after stunning. Velocity of the captive bolt and its physical parameters were calculated. Cattle shot with low pressures showed more rhythmic respiration (27 vs. 8%, P<0.001), less tongue protrusion (4 vs. 12%, P=0.03) and less masseter relaxation (22 vs. 48%, P<0.001). There was an increased frequency of shots in the ideal position when cattle were shot with the low compared to high airline pressures (15.3 vs. 3.1%). Bolt velocity and its physical parameters were significantly (P<0.01) higher when using high pressure. Airline pressures below 190psi are inappropriate when shooting adult Zebu beef cattle with pneumatically powered penetrating captive bolt guns. Copyright © 2017 Elsevier Ltd. All rights reserved.

Radiation exposure of German aircraft crews under the impact of solar cycle 23 and airline business factors.

Science.gov (United States)

Frasch, Gerhard; Kammerer, Lothar; Karofsky, Ralf; Schlosser, Andrea; Stegemann, Ralf

2014-12-01

The exposure of German aircraft crews to cosmic radiation varies both with solar activity and operational factors of airline business. Data come from the German central dose registry and cover monthly exposures of up to 37,000 German aircraft crewmembers that were under official monitoring. During the years 2004 to 2009 of solar cycle 23 (i.e., in the decreasing phase of solar activity), the annual doses of German aircraft crews increased by an average of 20%. Decreasing solar activity allows more galactic radiation to reach the atmosphere, increasing high-altitude doses. The rise results mainly from the less effective protection from the solar wind but also from airline business factors. Both cockpit and cabin personnel differ in age-dependent professional and social status. This status determines substantially the annual effective dose: younger cabin personnel and the elder pilots generally receive higher annual doses than their counterparts. They also receive larger increases in their annual dose when the solar activity decreases. The doses under this combined influence of solar activity and airline business factors result in a maximum of exposure for German aircrews for this solar cycle. With the increasing solar activity of the current solar cycle 24, the doses are expected to decrease again.

Employee engagement is a fundamental component of quality healthcare. In order to provide empirical data of engagement in NHS Scotland an Employee Engagement Index was co-constructed with staff. 'iMatter' consists of 25 Likert questions developed iteratively from the literature and a series of validation events with NHS Scotland staff. The aim of this study was to test the face, content and construct validity of iMatter. Cross sectional survey of NHS Scotland staff. In January 2013 iMatter was sent to 2300 staff across all disciplines in NHS Scotland. 1280 staff completed it. Demographic data were collected. Internal consistency of the scale was calculated. Construct validity consisted of concurrent application of factor analysis and Rasch analysis. Face and content validity were checked using 3 focus groups. The sample was representative of the NHSScotland population. iMatter showed very strong reliability (α = 0.958). Factor analysis revealed a four-factor structure consistent with the following interpretation: iMatter showed evidence of high reliability and validity. It is a popular measure of staff engagement in NHS Scotland. Implications for practice focus on the importance of coproduction in psychometric development.

Lategola, M.T.; Melton, C.E.; Higgins, E.A.

1980-09-01

Previous studies showed that the ozone concentration for pulmonary and symptom threshold effects in flight attendant surrogates lies between 0.20 and 0.30 ppMv for a 3-h exposure with intermittent treadmill exercise at 1829 m (MSL) stimulated cabin altitude. In the present study of sedentary occupants of the in-flight airline cabin, the same protocol was used except for omitting all treadmill exercise. Symptoms were assessed with a standardized questionnaire. Pulmonary function was assessed using standardized quantitative spirometry. Male smoker and nonsmoker airline passenger and cockpit crew surrogates 40 to 59 years of age were used. Small but statistically significant displacements occurred in symptoms and in some spirometry parameters. In general, the younger subjects appeared more sensitive to ozone than the older subjects. No significant differences appeared between smokers' and nonsmokers' responses to ozone exposure. It is concluded that the ozone threshold of these sedentary surrogates under these experimental conditions is right at 0.30 ppMv.

The objective of this study is to determine risk factors for fatigue among airline pilots, taking into account person-, work-, health-, sleep-, and lifestyle-related characteristics. The study population consisted of 502 pilots who participated in the MORE Energy study. Included risk factors were either measured through an online questionnaire or provided by the company. The outcome of this study, fatigue, was assessed using the Checklist Individual Strength (CIS), and was defined as scoring more than 76 points on this questionnaire. The association of the risk factors with fatigue was determined using univariate and multivariate logistic regression analyses. Of the participating pilots, 29.5 % scored more than 76 points on the CIS and were classified as being fatigued. The fully adjusted regression model showed that person-, work-, health-, and lifestyle-related characteristics were associated with fatigue. Pilots who were aged 31 to 40 (OR 3.36, 95 % CI 1.32-8.53) or 41 to 50 (OR 4.19, 95 % CI 1.40-12.47), an evening type (OR 2.40, 95 % CI 1.38-4.16), scored higher on work-life balance disturbance (OR 1.22, 95 % CI 1.10-1.36), scored higher on need for recovery (OR 1.02, 95 % CI 1.01-1.04), scored lower on general health perception (OR 0.31, 95 % CI 0.20-0.47), were less physically active (OR 0.77, 95 % CI 0.66-0.89), and had a moderate alcohol consumption (OR 3.88, 95 % CI 1.21-12.43), were at higher risk for fatigue. Higher age, being an evening type, disturbance of the work-life balance, more need for recovery, a lower perceived health, less physical activity, and moderate alcohol consumption were shown to be risk factors for fatigue. Further longitudinal research is needed to elucidate the direction of the associations found and to evaluate the effects of possible countermeasures in airline pilots.

Hand and nasal samples of flight-catering staff were collected from 1995 to 1997 to find employees carrying Staphylococcus aureus. Altogether 153 hand samples and 136 nose samples were taken. Nasal sampling showed a higher prevalence of S. aureus among food handlers (29%) than hand sampling (9%). A high proportion of the strains (46%) were enterotoxigenic, and a considerable amount of food handlers carried enterotoxigenic S. aureus, 6% and 12% according to hand and nasal sampling, respectively. Pulsed-field gel electrophoresis macrorestriction profiles revealed a total of 32 different types associated with the 35 employees carrying S. aureus. In most cases, the same type colonized both the hand and nose of a person. Despite the wide variety of types found, one strain colonized five persons and the second most common strain was associated with four food handlers. The predominant toxin produced was B, which was produced by the most common strain. The results showed that nasal sampling is a good way to detect S. aureus carriers, whereas hand sampling may fail to reveal carriers. The high proportion of enterotoxigenic strains show that a food handler harboring S. aureus must be considered a potential source of enterotoxigenic strains for airline meals.

Changes are discussed in flux density of cosmic radiation particles with time as are the origin of cosmic radiation, the level of cosmic radiation near the Earth's surface, and the determination of cosmic radiation doses in airliners. Doses and dose rates are given measured on different flight routes. In spite of the fact that the flight duration at an altitude of about 10 km makes for about 80% of the total flight time, the overall radiation burden of the crews at 1000 flight hours a year is roughly double that of the rest of the population.

Worldwide, 2.75 billion passengers fly on commercial airlines annually. When in-flight medical emergencies occur, access to care is limited. We describe in-flight medical emergencies and the outcomes of these events. We reviewed records of in-flight medical emergency calls from five domestic and international airlines to a physician-directed medical communications center from January 1, 2008, through October 31, 2010. We characterized the most common medical problems and the type of on-board assistance rendered. We determined the incidence of and factors associated with unscheduled aircraft diversion, transport to a hospital, and hospital admission, and we determined the incidence of death. There were 11,920 in-flight medical emergencies resulting in calls to the center (1 medical emergency per 604 flights). The most common problems were syncope or presyncope (37.4% of cases), respiratory symptoms (12.1%), and nausea or vomiting (9.5%). Physician passengers provided medical assistance in 48.1% of in-flight medical emergencies, and aircraft diversion occurred in 7.3%. Of 10,914 patients for whom postflight follow-up data were available, 25.8% were transported to a hospital by emergency-medical-service personnel, 8.6% were admitted, and 0.3% died. The most common triggers for admission were possible stroke (odds ratio, 3.36; 95% confidence interval [CI], 1.88 to 6.03), respiratory symptoms (odds ratio, 2.13; 95% CI, 1.48 to 3.06), and cardiac symptoms (odds ratio, 1.95; 95% CI, 1.37 to 2.77). Most in-flight medical emergencies were related to syncope, respiratory symptoms, or gastrointestinal symptoms, and a physician was frequently the responding medical volunteer. Few in-flight medical emergencies resulted in diversion of aircraft or death; one fourth of passengers who had an in-flight medical emergency underwent additional evaluation in a hospital.

Wagstaff, Anthony S; Arva, Per

2009-10-01

In order to investigate possible hearing loss as a consequence of aviation noise, a comparative analysis of audiometric data from Norwegian Air Traffic Control (ATC) personnel, airline (fixed-wing) pilots, and helicopter pilots was performed. The results may be of use in giving advice regarding preventive measures. Male ATC, airline, and helicopter pilots were selected randomly from the Civil Aviation Authority (CAA) medical files. There were 182 subjects included in the study: 50, 81, and 51 subjects for ATC, helicopter, and airline pilots, respectively. Two audiograms with a 2-3-yr interval were analyzed for each individual. Age correction was performed using data from ISO 7129. Threshold changes per year for the frequencies 3, 4, and 6 kHz were examined in particular after age correction. For all three groups, mean hearing threshold levels were above (worse than) ISO 7129 predictions for most frequencies. As expected, hearing thresholds increased with age in the group as a whole. Looking at the 3-, 4-, and 6-kHz frequencies in particular, all groups had small but highly significant increases in hearing thresholds at 4 kHz between the first and second audiogram. The mean hearing thresholds for this group of aviation personnel are higher than International Standard ISO-7129 would predict according to age. Highly significant changes in hearing threshold after age correction, indicating possible noise-induced hearing loss, were found in all groups at 4 kHz. The fact that helicopter pilots had similar hearing loss to their other aviation colleagues indicates that current hearing protection for these pilots is effective in counteracting the increased noise levels in helicopters.

2012-01-01

Many companies currently strive to support their employees' work-life balance through appropriate measures in order to improve employees' loyalty towards the company and to recruit new employees. In this context, flexibility in the area of working times is a measure that can influence employees' private lives immensely. This is why the individualisation of working time arrangements has been accorded high importance in current discussions on work-life balance. In this area, best practice examples can be found showing how working-time arrangements can improve the situation of the employees. It should be noted, however, that there is not one single perfect working-time model. A working-time model must always be adapted specifically to the actual situation of the company and the employees. Therefore, a targeted analysis of the challenges facing the company and the demands on the employees is essential for the creation of an appropriate working time policy. In particular, the employees' working-time preferences must be appropriately taken into account. Owing, however, to a combination of organisational complications and legal data protection restrictions, it is for the most part impossible to meet these working-time preferences in their entirety. This paper, which is based on an employee survey, illustrates the strain on employees in the retail sector and identifies different types of working-time preferences.

remote online ergonomic assessment in the office environment as compared to face-to-face ergonomic assessment and examination of the applicability of remote online ergonomic assessment to office workers. 40 employees from a large Israeli hi-tech company were ergonomically assessed per the University of California computer usage checklist, according to the two assessment types (face-to-face and remote). An additional Ergonomist "assessor 2" examined the credibility of the process. Research hypothesis 1 was verified: 21 out of 22 questions (95.45%) from the checklist indicated compatibility between "assessor 1" to the "Gold Standard" at an 80% level. Research hypothesis 2: examining the credibility between the assessors with regard to remote assessment. This hypothesis was partially verified, the correlation between the assessors was measured at 0.54. Research hypothesis 3: examining the extent of deviation of natural posture between distal body parts assessment (distant from the center of the body) and proximal body parts (close to the center of the body). This hypothesis was clearly verified. It has been proven that there is statistical significance between the results. The current research has proved that there is an additional method to assess musculoskeletal disorders risk factors remotely online at office environment.

The effects of risk perception and flight experience on airline pilots' locus of control with regard to safety operation behaviors.

You, Xuqun; Ji, Ming; Han, Haiyan

2013-08-01

The primary objective of this paper was to integrate two research traditions, social cognition approach and individual state approach, and to understand the relationships between locus of control (LOC), risk perception, flight time, and safety operation behavior (SOB) among Chinese airline pilots. The study sample consisted of 193 commercial airline pilots from China Southern Airlines Ltd. The results showed that internal locus of control directly affected pilot safety operation behavior. Risk perception seemed to mediate the relationship between locus of control and safety operation behaviors, and total flight time moderated internal locus of control. Thus, locus of control primarily influences safety operation behavior indirectly by affecting risk perception. The total effect of internal locus of control on safety behaviors is larger than that of external locus of control. Furthermore, the safety benefit of flight experience is more pronounced among pilots with high internal loci of control in the early and middle flight building stages. Practical implications for aviation safety and directions for future research are also discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

Managing the employee's soul: Foucault applied to modern management technologies

Directory of Open Access Journals (Sweden)

Kaspar Villadsen

Full Text Available This paper presents an alternative approach to analyse power in modern organisations. It does so by applyingFoucauldian concepts to new types of management technologies, which are directed at the employee's personality. Most often, studies of power and management focus on organisational structures, power games between groups and issues of how to manage processes within and between organisations. We rarely talk about whatcould be termed 'the management of personality'. This paper argues, however, that this kind of Human Resource Management is becoming increasingly important and should be a key focus in critical organisational analysis. It also discusses the consequences and possibilities for employees facing a proliferation of management-ofpersonality technologies.

Anne Arundel Medical Center has been on a 3-year journey to improve employee well-being with the assumption that employee well-being and employee engagement are interconnected. Improvements in employee well-being will result in increased employee engagement and will be a pivotal driver to assist the health system meet its goals. Historically, Anne Arundel Medical Center successfully differentiated itself in the market by being the region's high-quality, low-cost provider of health services delivered through intense collaboration with patients and families. The financial, quality, and patient satisfaction results are in the top percentiles nationwide. However, as the pace of change accelerates and the organization faces increased pressure to improve outcomes, keeping employees from becoming burned out and disengaged becomes an increasing concern. The WellBeing framework was developed on the basis of the work of Tom Rath and Jim Harter as the model to support Anne Arundel's WellBeing work. The efforts around well-being are comprehensive and impact all aspects of how work is conducted. Employee well-being has been elevated to an equal third prong along with providing high-quality low-cost care in a patient-centered environment. This focus on leading an employee WellBeing Program has resulted in improved engagement scores at Anne Arundel Medical Center.

Airline view of LH2 as a fuel for commercial aircraft

Energy Technology Data Exchange (ETDEWEB)

Wilkinson, K.G.

1983-01-01

Fuel for air transport is a particularly important matter, because it is an energy-intensive form of transport. Price and energy density are therefore correspondingly critical. Airlines views tend to be short term because there is no future if they do not survive tomorrow. Thus, although petroleum supply and price has been unstable since 1973, airlines' primary concern has been with economizing the use of fuel and specifying more fuel economic equipment for the future, rather than serious pursuit of more radical solutions. LH2 gives promise of being a serious candidate for the longer term, but there is not yet convincing proof that cheaper seat mile costs could be produced in today's circumstances. The situation could be changed by the realization of laminar flow by surface cooling at subsonic speeds. There is a strong case for a modest programme of carefully aimed research on an international basis to fill the most important gaps in our knowledge on the design of LH2 fueled aircraft. Future crises in energy supplies may well raise questions of transport fuel strategy which will heed this background for wise decision-making. Particular significance attaches to the place of nuclear power in world energy policy since this dominates the question of LH2 availability and price. 2 references, 2 figures.

In human resource management, employee performance is strongly affected by both formal and informal employee networks. Most previous research on employee performance has focused on monolayer networks that can represent only single categories of employee social relationships. We study employee performance by taking into account the entire multiplex structure of underlying employee social networks. We collect three datasets consisting of five different employee relationship categories in three firms, and predict employee performance using degree centrality and eigenvector centrality in a superimposed multiplex network (SMN) and an unfolded multiplex network (UMN). We use a quadratic assignment procedure (QAP) analysis and a regression analysis to demonstrate that the different categories of relationship are mutually embedded and that the strength of their impact on employee performance differs. We also use weighted/unweighted SMN/UMN to measure the predictive accuracy of this approach and find that employees with high centrality in a weighted UMN are more likely to perform well. Our results shed new light on how social structures affect employee performance.

Burslem, C D; Kelly, M J; Preston, F S

1990-01-01

In the spring of 1984, British Airways was involved in a major food poisoning outbreak which affected nearly 1000 passengers, aircrew and ground personnel. The operational impact was worldwide and could have resulted in the cessation of the airline's day-to-day operations. The investigation paralleled a major aircraft disaster in the number of national and international agencies involved and in the variety of disciplines engaged. Although the causative organism was rapidly identified (salmonella), and its introduction into the food chain proved to be a key factor, the scale of the outbreak was the result of an interaction of other factors. As with a major aircraft accident, none of the factors alone would have caused the near disaster that occurred.

The Transition from Alliance Networks to Multilateral Alliances in the Global Airline Industry

Directory of Open Access Journals (Sweden)

Sergio G. Lazzarini

2008-01-01

Full Text Available This study examines conditions in which alliance networks (informal webs of bilateral entanglements between firms may or may not evolve into multilateral alliances (broad, formal multiple-firm arrangements. I offer a theory to explain the formation of multilateral alliances based on both the resource profile and the structure of existing interfirm networks, and provide an initial test of that theory in the context of the global airline industry. Using data from 75 global airlines and their alliances, I propose a methodology to retrieve samples of alliance networks and then use regression analysis to assess how the resource profile and the structure of these networks influence their formalization into multilateral alliances. I find that multilateral alliances are more likely to emerge when alliance networks exhibit high resource diversity and network structure characterized by moderate density and high centralization. Apparently, while highly sparse networks reduce actors’ awareness of their potential joint collaboration, highly dense or embedded networks substitute for the need for formal controls accompanying multilateral agreements. The effect of centralization suggests that the formation of multilateral alliances tends to be triggered by leading actors directly connected to other network members.

An audit of employee commitment to enable leaders to manage organisational talent

Full Text Available Leaders in motor manufacturing companies are faced with the challenge of talent attraction, development and retention due to constant changes in manufacturing technology. Yet, these leaders are expected to recruit, train and retain specialist skills due to the highly specialised nature of their manufacturing business processes. Another threat faced by these leaders is the loss of skilled talent to their competitors. These challenges have, therefore, created the need to audit employee commitment in a manufacturing organisation in order to enable leaders to initiate talent management practices. It is against this background that this paper poses the question: What is the nature of organisational commitment of manufacturing employees for leaders to be able to manage talent? This question was addressed through a quantitative study of organisational commitment dimensions. The main objective of this study was to audit the organisational commitment dimensions (as measured by Meyer and Allen’s Organizational Commitment Scale within a manufacturing organisation. The data was collected using a survey on a random sample size of N=371, all of whom were employees of a South African motor manufacturing organisation. The results of this study indicate that there are significant differences between organisational commitment dimensions namely; affective, normative and continuance commitments. These findings provide valuable information to assist leaders to propose talent management interventions vital for organisational talent attraction, development and retention.

Employees, many of whom are not native English speakers, perform the majority of work on large US dairy farms. Although management of employees is a critical role of dairy owners and managers, factors that improve employee engagement and retention are not well known. Objectives were to (1) identify key dairy farm employee management issues based on employee perceptions, (2) evaluate strengths and weaknesses of farms based on employee responses, (3) investigate differences between Latino and English-speaking employees, and (4) investigate differences in perception between employers and employees. Employees from 12 US dairy farms (each with a minimum of 10 employees) were interviewed by phone following a questionnaire provided. Employees provided their responses to 21 Likert scale questions and 8 open-ended questions. There was a wide range in employee turnover among farms (100%). Latino employees had much shorter tenure and were more often employed in milking and livestock care than English-speaking employees. Employee perceptions differed among farms regarding whether they would recommend their farm as a place to work, teamwork within the dairy, whether rules were fairly applied, availability of tools and equipment, clear lines of supervision, and recognition for good work in the previous 15 d. Latino employees (n = 91) were more positive in many of these measures than their English-speaking counterparts (n = 77) but less often provided ideas to their employer on how to improve the business. Employers, surveyed on how they thought their employees would answer, underestimated employee responses on several questions, particularly the interest of employees in learning about dairy. When asked to cite 3 goals of the operation, there were differences among owners, managers, and employees. Although employees rated their commitment to the farm and their interest in learning as high, based on turnover, there was an obvious disparity between reality and ideal employee

Employee assistance program evaluation. Employee perceptions, awareness, and utilization.

Moore, T

1989-12-01

Periodic evaluation is necessary to maintain a quality employee assistance program. This survey was undertaken to determine employee awareness of the existing EAP and their satisfaction with the program. Likewise, the survey allowed for employee input on areas of the program they had concerns with that may have caused hesitancy in further use of the program. The survey not only documents to management that the program is of value to employees and identifies areas where changes may be focused in the future to meet employee needs, but actually serves as a communication tool in itself as a reminder of the availability of the Employee Assistance Program.

In 2010, malaria caused approximately 216 million infections in people and 655,000 deaths. In the United States, imported malaria cases occur every year, primarily in returning travelers and immigrants from endemic countries. In 2010, five Plasmodium falciparum malaria cases occurred among crew members of one US commercial airline company (Airline A). This investigation aimed to assess the malaria prevention knowledge, attitudes, and practices (KAP) of Airline A crew members to provide information for potential interventions. The web link to a self-administered on-line survey was distributed by internal company communications to Airline A pilots and flight attendants (FA) eligible for international travel. The survey collected demographic information as well as occupation, work history, and malaria prevention education. Of approximately 7,000 nonrandomly selected crew members, 220 FA and 217 pilots completed the survey (6%). Respondents correctly identified antimalarial medication (91% FA, 95% pilots) and insect repellents (96% FA, 96% pilots) as effective preventive measures. While in malaria-intense destinations, few FA and less than half of pilots always took antimalarial medication (4% FA, 40% pilots) yet many often spent greater than 30 minutes outdoors after sundown (71% FA, 66% pilots). Less than half in both groups always used insect repellents (46% FA, 47% pilots). Many respondents were unaware of how to get antimalarial medications (52% FA, 30% pilots) and were concerned about their side effects (61% FA, 31% pilots). Overall, FA and pilots demonstrated good knowledge of malaria prevention, but many performed risky activities while practicing only some recommended malaria preventive measures. Malaria prevention education should focus on advance notification if traveling to a malaria-endemic area, how to easily obtain antimalarial medications, and the importance of practicing all recommended preventive measures. © 2012 International Society of Travel

When daily planning improves employee performance: The importance of planning type, engagement, and interruptions.

Science.gov (United States)

Parke, Michael R; Weinhardt, Justin M; Brodsky, Andrew; Tangirala, Subrahmaniam; DeVoe, Sanford E

2018-03-01

Does planning for a particular workday help employees perform better than on other days they fail to plan? We investigate this question by identifying 2 distinct types of daily work planning to explain why and when planning improves employees' daily performance. The first type is time management planning (TMP)-creating task lists, prioritizing tasks, and determining how and when to perform them. We propose that TMP enhances employees' performance by increasing their work engagement, but that these positive effects are weakened when employees face many interruptions in their day. The second type is contingent planning (CP) in which employees anticipate possible interruptions in their work and plan for them. We propose that CP helps employees stay engaged and perform well despite frequent interruptions. We investigate these hypotheses using a 2-week experience-sampling study. Our findings indicate that TMP's positive effects are conditioned upon the amount of interruptions, but CP has positive effects that are not influenced by the level of interruptions. Through this study, we help inform workers of the different planning methods they can use to increase their daily motivation and performance in dynamic work environments.

Tveten, U.; Haldorsen, T.; Reitan, J.

2000-01-01

The project presented here has been carried out as part of an epidemiological project on Norwegian aircraft personnel, entitled 'Exposure to low level ionising radiation and incidence of cancer in airline pilots and crew'. The purpose of the main project is to determine if there may be a relationship between exposure to cosmic radiation at aircraft cruising altitudes and the incidence of cancer. The methodology used as basis for estimating the radiation exposures is presented. The information used as basis for the dose estimations comes from a variety of sources: the files at the Personnel Licensing Section and the Aviation Medical Section of Norwegian Aviation Administration, the route tables of Scandinavian Airlines System (SAS), large amounts of expert information contributed by members of the Pilot's Associations in Norway and a couple of non-Norwegian pilots and from other members of the staff of SAS and other airlines. The estimation for each pilot was based on individual information of annual block hours and an estimated dose rate for each type of aircraft. The latter was estimated as a weighted average of CARI-estimated doses on a selection of routes flown by the airplanes in the different time periods. The project includes all pilots that have been licensed in Norway since 1946. These pilots have been flying a large variety of different types of aircraft and routes. The cosmic radiation intensity is a function of altitude in the atmosphere and, less markedly, of geographical latitude and of the intensity of the radiation from the sun (quantified as the heliocentric potential). Different types of aircraft fly at different altitudes and are used for different purposes (passenger traffic, cargo, air photography, preparation of maps etc) and used on different routes. The end results of the project described in this article are radiation exposures per block hour for each type of aircraft, and for each individual year (the differences between years reflect the

A Theory of False Cognitive Expectancies in Airline Pilots

Science.gov (United States)

Cortes, Antonio I.

The Theory of False Cognitive Expectancies was developed by studying high reliability flight operations. Airline pilots depend extensively on cognitive expectancies to perceive, understand, and predict actions and events. Out of 1,363 incident reports submitted by airline pilots to the National Aeronautics and Space Administration Aviation Safety Reporting System over a year's time, 110 reports were found to contain evidence of 127 false cognitive expectancies in pilots. A comprehensive taxonomy was developed with six categories of interest. The dataset of 127 false expectancies was used to initially code tentative taxon values for each category. Intermediate coding through constant comparative analysis completed the taxonomy. The taxonomy was used for the advanced coding of chronological context-dependent visualizations of expectancy factors, known as strands, which depict the major factors in the creation and propagation of each expectancy. Strands were mapped into common networks to detect highly represented expectancy processes. Theoretical integration established 11 sources of false expectancies, the most common expectancy errors, and those conspicuous factors worthy of future study. The most prevalent source of false cognitive expectancies within the dataset was determined to be unconscious individual modeling based on past events. Integrative analyses also revealed relationships between expectancies and flight deck automation, unresolved discrepancies, and levels of situation awareness. Particularly noteworthy were the findings that false expectancies can combine in three possible permutations to diminish situation awareness and examples of how false expectancies can be unwittingly transmitted from one person to another. The theory resulting from this research can enhance the error coding process used during aircraft line oriented safety audits, lays the foundation for developing expectancy management training programs, and will allow researchers to proffer

Full text: Introduction: In commercial aviation the most important determinants of radiation exposure in humans are the altitude, latitude, flight duration and the solar cycle's period. This study was conducted to address this type of exposure trough radiation dosimetry. Method: The study was performed in the business-class cabin of an Airbus 340-200 aircraft, provided by Argentine Airlines, during 2 flights routes: New York-Miami-Buenos Aires (trans equatorial) and Buenos Aires-Auckland (circumpolar). Measurements addressed the electromagnetic spectrum or low Linear Energy Transfer (LET) and corpuscular radiation (High LET). The instruments used were an Ion Chamber (IC), to measure the ionizing component of radiation (i.e., gamma radiation), the SWENDI, to measure only the neutron component, and the Tissue Equivalent Proportional Counter (TEPC) for measuring all radiation types. Results: The routes' dose rates are presented in the table. TEPC rates agreed with the LET findings. The total dose rates of high latitude flights were higher than those of low latitude flights. The SWENDI (High LET) results for the flights over the equator, at low latitude, represented only 1/3 of the total radiation. The New York-Miami and Buenos Aires-Auckland flights, at high latitude, represented just under 1/2 of the Total radiation (-45%). Conclusion: Based on the results of this study, the annual dose rates of radiation exposure of air crew personnel serving on international flights offered by Argentine Airlines is between 3 and 7 mSv. This rate is higher than the maximum recommended for the general population by the International Commission on Radiological Protection (ICRP), which is 1 milli Sv./y. Therefore, these personnel must be officially considered 'Occupationally Exposed to Radiation' in way to provide the appropriate measures that must be implemented for their protection in accordance to ICRP guidelines. Dose(uSv): Route N Y-Miami, IC 6.07, SWENDI 5.07, TEPC 11.04; Route

2010-08-01

Abstract We investigate the structural properties of Chinese city airline network (CCAN), where nodes and edges denote cities and direct flights. The degree distribution follows a double power law and a clear hierarchical layout is observed. The population exhibits a weakly positive correlation with the number of flights, yet it does not show obvious correlation with the transportation flow. The distance is an important parameter in CCAN, that is, the number of flights decays fast with the increasing of the distance. In comparison, the tertiary industry has the most important influence on the Chinese air passenger transportation. Statistically speaking, when the tertiary industry value increases by 1%, the next period's volume will increase by 0.73%.
