Initial Validation Of Novel Performance-based Measures: Mental Rotation And Psychomotor Ability

Fatolitis, Philip 01 January 2008 (has links)
Given the high-risk nature of military flight operations and the significant resources required to train U.S. Naval Aviation personnel, continual improvement is required in the selection process. In addition to general commissioning requirements and aeromedical standards, the U.S. Navy utilizes the Aviation Selection Test Battery (ASTB) to select commissioned aviation students. Although the ASTB has been a good predictor of aviation student performance in training, it was proposed that incremental improvement could be gained with the introduction of novel, computer administered performancebased measures: Block Rotation (BRT) and a Navy-developed Compensatory Tracking task. This work constituted an initial validation of the BRT, an interactive virtual analog of Shepard-Metzler’s (1971) Mental Rotation task that was developed with the intention of quantifying mental rotation and psychomotor ability. For Compensatory Tracking, this work sought to determine if data gathered concord with results in extant literature, confirming the validity of the task. Data from the BRT were examined to determine task reliability and to formulate relevant quantitative/predictive performance human models. Results showed that the BRT performance is a valid spatial ability predictor whose output can be modeled, and that Compensatory Tracking task data concord with the psychometric properties of tracking tasks that have been previously presented in the literature.

[pt] EVIDÊNCIAS DE VALIDADE INTERNA E EXTERNA DO INVENTÁRIO DE BURNOUT NO TRABALHO EM UMA AMOSTRA DE PILOTOS MILITARES BRASILEIROS / [en] VALIDITY EVIDENCE FOR THE JOB BURNOUT INVENTORY IN A SAMPLE OF BRAZILIAN MILITARY PILOTS

LIVIA FARIAS DOS SANTOS 25 June 2020 (has links)
[pt] A Síndrome de Burnout é uma reação ao estresse duradouro no ambiente de trabalho e traz prejuízos tanto para o indivíduo quanto para a organização na qual ele está inserido. Ela pode acometer profissionais de diversos setores, impactando na saúde mental e no desempenho dos trabalhadores. Assim, é importante que existam instrumentos capazes de avaliar os sintomas de burnout em grupos ocupacionais distintos. O objetivo da presente pesquisa foi buscar evidências de validade baseada na estrutura interna e na relação com variáveis externas do Inventário de Burnout no Trabalho (IBT) em uma amostra de pilotos militares brasileiros. A amostra foi composta por 259 pilotos militares (98,1 por cento homens), de todas as regiões do Brasil. Foram conduzidas análises fatoriais confirmatórias a fim de verificar a plausibilidade de diferentes estruturas fatoriais do instrumento: unidimensional, tridimensional e um modelo de segunda ordem. O modelo tridimensional e o de segunda ordem apresentaram índices de ajuste satisfatórios (CFI igual 0,956; TLI igual 0,951; RMSEA igual 0.090 (0,083 - 0,097)). As cargas fatoriais também foram satisfatórias, com variações de 0,657 a 0,958. Além disso, os escores de burnout apresentaram relação forte e positiva com as variáveis neuroticismo, ansiedade, estresse e depressão e correlação forte e negativa com engajamento e satisfação no trabalho. Pode-se concluir que o IBT é uma medida confiável para a avaliação do burnout em pilotos militares brasileiros. / [en] Burnout Syndrome is a reaction to chronic stress in the workplace and causes harm to both the individual and the organization in which he is inserted. It can affect professionals from various sectors, impacting mental health and worker performance. Thus, it is important to have measures capable of assessing burnout symptoms in different occupational groups. The aim of this research was to look for evidence of validity based on the internal structure and relationship with external variables of the Burnout at Work Inventory (IBT) in a sample of Brazilian military pilots. The sample consisted of 259 military pilots (98.1 per cent men) from all regions of Brazil. Confirmatory factor analyzes were conducted to verify the plausibility of different factor structures of the instrument: one-dimensional, three-dimensional and a second-order model. The three-dimensional model and the second-order model presented satisfactory adjustment indices (CFI equal 0.956; TLI equal 0.951; RMSEA equal 0.090 (0.083 - 0.097)). The factor loadings were also satisfactory, ranging from 0.657 to 0.958. In addition, burnout scores showed a strong and positive relationship with the variables neuroticism, anxiety, stress and depression and a strong and negative correlation with engagement and job satisfaction. It can be concluded that IBT is a reliable measure for the evaluation of burnout in Brazilian military pilots.

The predictive validity of the selection battery for trainee pilots in the South African Air Force

Flotman, Aden-Paul 30 June 2002 (has links)
The sample comprised 92 candidates who have completed the Ground School Phase of the trainee pilot training programme. The independent variables are Raven's Advanced Progressive Matrices Test, the Blox Test and the Vienna Determination Test. The dependent variable is the candidates' results after the Ground School Phase of their training. The results indicated that only the Advanced Ravens test and the Vienna Determination test (Phase 3} correlate positively with the Ground School Phase results of the candidates. The current battery emphasises cognitive abilities and psycho-motor functioning and does not cover personality traits of prospective candidates. It is recommended that new instruments are included (to cover the measurement of personality traits), that the sample size should be increased by promoting pilot training among previously disadvantaged students and that the current pilot profile should be updated as a matter of urgency. / Industrial and Organisational Psychology / M.A. (Industrial Psychology)

The retention of scarce skills : a study focused on South African Air Force pilot retention and reducing employee turnover

Wood, Craig Warren Barrie 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: The South African Air Force (SAAF) is loosing pilots at an alarming rate and if not addressed with a matter of urgency will become the most critical problems facing the Air Force in the future. This study analyses the problem in comparison to other Air Forces, and how airline hiring and lack of Air Force leadership are contributing to the current situation. Employee retention is a problem inherent in most organisations. The study also examines the reasons that motivate employees to leave any organisation and what world-class organisations are doing to reduce employee turnover. This is used as a logical starting point towards finding a long-term solution as to how the Air Force can retain its pilots. This solution includes increasing pay, dealing with quality of life issues and by examining job and career issues. The paper concludes that the implementation of a multi-faceted solution will allow the Air Force and other organisations to retain its essential core of pilots/employees in spite of increased competition from other employers. / AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse Lugmag (SALM) verloor tans sy vlieëniers teen 'n hewige tempo, en as hierdie toestand nie dadelik en met erns aangespreek word nie, sal dit seer sekerlik die mees kritiese probleem word wat die SALM in die toekoms in die gesig sal staar. Hierdie geskryf staan te doel om die probleem te analiseer vergelyke te trek met ander Lugmagte, asook hoe lugredery aanstellings en die te kort aan Lugmag leierskap die huidige situasie vererger. Werknemer retensie is 'n inherente probleem in meeste organisasies. Hierdie studie ondersoek verder, die redes wat werknemers motiveer om 'n betrokke organisasie te verlaat, asook wat wêreldklas organisasies tans doen om werknemer omset te verminder. Dit word dan as 'n logiese vertrekpunt gebruik om 'n langtermyn oplossing te vind waarmee die SALM sy vlieëniers sal kan behou. Die oplossing sluit in verhoogde en meer kompeterende salaris pakkette, beter hanteering van kwessies met betrekking tot die standaard van lewensgehalte asook die ondersoek na beter werksomstanighede en loopbaan moontlikhede. Die geskryf sluit af met die gevolgtrekking dat slegs die implementering van 'n multi-faset oplossing die SALM, en ander organisasies, in staat sal stel om sy/hulle essensiële kern van vlieëniers/werknemers te behou, ten spyte van verhoogde kompetisie van ander werkgewers.

Les pilotes comme agents de changement dans les télécentres communautaires au Mali

Traoré, Cheick Oumar 09 1900 (has links)
Cette thèse porte sur les processus de sélection, formation et encadrement (SFE) des gestionnaires, appelés pilotes et considérés comme agents de changement dans les télécentres communautaires au Mali. Ces processus sont étudiés sous l'angle de leur contribution positive ou négative à l'implantation et au développement de ces centres. Les projets "technologies de l’information et de la communication", initiés par les partenaires techniques et financiers, répondent au besoin des autorités maliennes préoccupées par un souci de connecter les 703 communes du pays. À la suite du sommet mondial sur la société de l’information en décembre 2003 à Genève, l’UNESCO et la Coopération suisse ont décidé d’installer des centres multimédias communautaires dans trois pays d’Afrique (Mali, Mozambique, Sénégal). Ces implantations de télécentres ont été réalisées sur le modèle de ce qui avait été fait en Asie sans tenir compte des besoins réels des bénéficiaires et des conditions particulières (économiques, politiques, culturelles) des sites d’implantation. Malgré les conditions parfois difficiles de l’Afrique, les populations témoignent un enthousiasme réel pour les technologies de communication. Les TIC ont connu une croissance considérable et se sont multipliées partout en Afrique, à des degrés divers. Néanmoins, elles n’ont pas encore atteint la majorité des populations africaines, car 70% de celles-ci vivent en zones rurales souvent marginalisées par les difficultés économiques. Après l’implantation des télécentres, les sites ont donc été confrontés à la difficile tâche de sélectionner les pilotes comme agents de changement. Les responsables chargés de la mise en œuvre des projets ont choisi les pilotes dans leur réseau familial. En ce sens, la thèse met l’accent sur l’importance du rôle d’un pilote dans un télécentre et l’appui qu’il peut générer dans la population bénéficiaire. Nous proposons un modèle qui part de l’action des agents de changement, et ce, afin de potentiellement susciter une prise de conscience chez les décideurs locaux. Nous avons fait une étude de cas sur quatre sites pour mieux connaître les processus de sélection, formation et encadrement des pilotes et nous avons tenté d'identifier les facteurs qui, dans ces processus, ont pu influencer le niveau de réussite de chacun de ces centres. / This dissertation examines the processes of selecting, training, and mentoring managers, also known as "pilots," and considered as change agents in the development of community telecentres in Mali. These processes are analyzed according to their positive and negative outcomes regarding the establishment and development of telecentres. The Information and Communication Technologies (ICT) project, launched by technical and financial partners, responds to the needs of Malian authorities in their efforts to connect the country’s 703 communes. Following the World Summit on the Information Society, held in Geneva on December 2003, UNESCO and the Swiss Agency for Development and Cooperation (SDC) decided to establish multimedia community telecentres in three African countries (Mali, Mozambique, and Senegal). The setting-up of these telecentres was modeled after a similar project conducted previously in Asia, without however taking into account the primary needs of the beneficiaries, nor their specific conditions (both economic, political, and cultural). Despite the difficult conditions that sometimes characterize the African context, African populations express a genuine interest for Information and Communication Technologies. The ICT sector has witnessed a considerable and widespread growth throughout many African countries, although with various degrees of success. However, a majority of the African population has still not been connected, since 70% of the population lives in more economically marginalized rural areas. Once the telecentres were established in various locations, most of them were confronted with the difficult challenge of selecting "pilots," to serve as change agents. Those in charge of selecting the pilots favored people located within their own family networks. Therefore, the dissertation emphasizes the pilot’s decisive role in the telecentres, and the support that he is able to generate within the beneficiary population. We put forward a model starting from the actions of the change agents, hoping to stimulate awareness amongst local deciders. We conducted a case study on four different sites in order to better understand the processes of selecting, training, and mentoring pilots, with a focus on the key factors influencing, for each of those processes, the level of success in all the telecentres.

"Man står ensam på toppen" : En undersökning om framtidens lotsutbildning / It's lonely at the top : A survey about the future of pilot education

Hultberg, Sebastian, Falk, Jonatan January 2019 (has links)
Lotsar måste anlitas av fartyg för att assistera vid hamnanlöp eller riskfyllda passager. Sjöfartsverket som arbetsgivare åt lotsarna ser problematik med rekrytering av nya lotsar som i kombination med pensionsavgångar skapar en brist av behöriga lotsar. Antagningskraven till den lotstjänst som finns idag är bland annat att sjöbefälet ska sjökaptensbehörighet. En smalare bas tillgängliga svenska sjöbefäl idag gör att Sjöfartsverket måste undersöka alternativa utbildningsmöjligheter till framtidens lotsar, för att säkerställa en tillräcklig bemanning på samtliga lotsstationer. Undersökningens syfte var att undersöka hur  framtida lotsutbildning och lotsrekrytering kan se ut för att möta framtidens behov av lotsar. Från semistrukturerade intervjuer med Sjöfartsverket, lotsar, sjökaptener och rederirepresentanten Svensk sjöfart framkom att flera alternativ är i konstruktionsfas men i stort bara preliminära. Bland alternativen finns en lotsutbildning på högskolenivå som påbyggnadsutbildning efter sjökaptensexamen. Centrala frågor i rekryteringsprocessen berör erfarenhet och utbildningens uppbyggnad. Sjöfartsverket anser att en förändring måste genomföras, men är osäkra på vilken lösning som är framtidssäker. / Pilots must be hired by vessels to assist in harbour manoeuvre or perilous passages. The Swedish Maritime Administration as an employer to the pilots sees problems with recruitment for pilot training, which in combination with pension departures creates a shortage of authorized pilots. The admission requirements for the pilot training available today include the Seaman to hold a master’s certificate. Fewer number of Swedish maritime officers available today forces the authority to examine alternative solutions to today's pilot training to ensure an adequate manning of all pilot stations. Conducting semi structured interviews carried out with the Swedish Maritime Administration, pilots, sea captains, Swedish Shipowners’ Association revealed that several options are in the design phase but largely only preliminary. Where among the alternative about a pilot training at tertiary level as postgraduate course after graduating the Nautical Science program. Key issues concern experience and the structure of education. The Maritime Administration only knows for sure that something has to be done but are unsure of which solution is future-proof.

Da torre de babel à torre de controle: desmistificando a linguagem dos céus. Um estudo descritivo da língua franca utilizada na comunicação piloto-controlador. / From babel tower to control tower: demystifying the language of the skies. A descriptive study of the lingua franca used into the communication between pilots and controllers.

Oliveira, Eduardo Silverio de 20 August 2007 (has links)
A língua franca utilizada na comunicação piloto-controlador ainda é pouco conhecida no meio acadêmico. Poucos estudos têm sido dedicados ao seu contexto de uso e ao mapeamento de suas características lingüísticas principais. Esta pesquisa acadêmica apresenta um estudo mais acurado da atividade de controlador de tráfego aéreo, no que se refere ao uso dessa linguagem de especialidade, além de desenvolver um estudo descritivo da língua franca utilizada na comunicação piloto-controlador para a identificação de suas características lingüísticas principais, com o recorte para a produção de material didático. Por meio da utilização do método do Professor André Camlong, a ferramenta computacional denominada STABLEX, fazemos uma análise descritiva, objetiva e indutiva de um corpus lingüístico, constituído dessa linguagem de especialidade. O que se pretende é oferecer subsídios aos professores de língua estrangeira para a produção do seu próprio material didático para o ensino dessa linguagem. É fato que, em determinados contextos de ensino, a necessidade de aprendizagem dos alunos é tão específica, que os materiais prontos para consumo, disponibilizados nas prateleiras das livrarias ou pelas editoras, não são suficientes, cabendo ao professor a tarefa de elaborá-los. No entanto, essa tarefa não tem se mostrado amistosa, já que o professor não dispõe de \"guias de orientação\", cientificamente justificáveis, para fazê-la. Assim sendo, o processo de elaboração torna-se intuitivo e empírico e, na grande maioria das vezes, restringese à adoção de fórmulas já consagradas de apresentação dos conteúdos. Acreditamos ser fundamental o correto entendimento das reais necessidades lingüísticas de um determinado público-alvo, para que haja mais condições de se estabelecerem processos mais ricos e eficientes de ensino e aprendizagem de qualquer língua estrangeira. / The lingua franca used in the communication between pilots and controllers is still not well known in the academic community. Few studies about its use and mapping of its main linguistic characteristics have been made. This theoretical research introduces an accurate study on the language used in the activity of air traffic controllers and develops a descriptive study of the lingua franca used in the communication between pilots and controllers, in order to identify its main linguistic characteristics towards material production. By using the method developed by Professor André Camlong and the computational tool STABLEX, an objective descriptive and inductive analysis of a linguistic corpus constituted by the language used in the ATC specialty has been conducted. The aim of this work is to provide language teachers with subsides for ATC material production hence helping teachers to elaborate materials that meet the very specific needs of their students based on the real needs of the stakeholders so as they can establish a more fruitful and efficient language teaching and learning process.

Étude du rôle des émotions sur les traitements différentiels mis en œuvre par des pilotes d'avions lors de la gestion de situations à risques sur simulateur de vol / Review of role of emotions on differential processing implemented by pilots of aircraft in the management of risk situations in flight simulator

Megret, Lise 18 February 2016 (has links)
Cette recherche porte sur l’impact des émotions sur les réponses des pilotes d’avion dans la gestion de situations dynamiques et ambiguës. A l’inverse des théories selon lesquelles les émotions dégradent les performances des pilotes, nous défendons la thèse selon laquelle les processus émotionnels ont une fonction adaptative et vont donc favoriser des réponses appropriées à la situation. Afin de vérifier cette hypothèse, des pilotes volontaires sont mis en situation de devoir gérer une fuite d’essence sur un simulateur de vol. Nous avons construit un scénario réaliste d’une durée d’une heure. Les pilotes ne sont donc pas confrontés à un problème ponctuel, s’apparentant à une situation de résolution de problèmes, mais doivent traiter l’anomalie de consommation d’essence pendant toute la durée du vol simulé. Ils ont donc la possibilité, en cours du vol, de corriger des choix qu’ils jugent inadaptés. Le relevé des fréquences cardiaques de chaque pilote pendant leur vol nous permet de repérer les épisodes émotionnels. Nous montrons que loin de dégrader les réponses des pilotes, les émotions sont positivement liées à la fois à leur expertise et à leurs performances : les pilotes ayant mis en œuvre les décisions les plus adaptées à la situation sont aussi ceux qui ont ressenti le plus d’émotions lors de la découverte et du traitement de la fuite d’essence. / This research centers on the impact of emotions on a pilot who's dealing with dynamic and/or ambiguous situations. Contrary to theories that state pilots' performances are diminished by emotions, we believe that an emotional process actually has an adaptive function which subsequently helps give appropriate answers to a given situation. To verify this hypothesis, volunteer pilots are confronted with having to deal with a fuel leakage on a flight simulator. We have built a realistic 1h long scenario. The pilots are not faced with a punctual situation, akin to problem solving, but have to treat the fuel consumption anomaly during the whole length of the flight simulation. Consequently they have the possibility, in flight, to recover inappropriate responses. The readings of the pilots' heartbeat allows us to identify the emotional episodes. We show that, far from diminishing the pilots' responses, emotions are linked positively not only to the pilots' expertise, but also their performances: The pilots who have devised the best responses to the situation are also those who've registered the most emotions whilst discovering and treating the fuel leakage.
