    The study explores the relationship between managerial skills and managerial effectiveness, measuring managerial effectiveness by four different methods. Evaluation of 96 top managers of fictitious companies by a group of 1,746 subordinates took place after three months of intensive cooperation during a managerial simulation game. All respondents were college students. Results show that different managerial effectiveness indicators have different sets of managerial skills predictors: Group performance (profit of company) is predicted by motivational skills; perceived effectiveness (evaluation by subordinates) is predicted by organizational skills and by motivational skills; organizational skills, communicational skills, and cooperativeness predict leadership emergence (assessed by subordinates); and evaluation and supervisory skills are the only predictor for leadership self-efficacy (self-evaluation of the manager). According to the results it is possible to recommend focusing especially on manager’s motivational skills in order to enhance team performance and on organizational skills for reinforcing manager’s position.The study explores the relationship between managerial skills and managerial effectiveness, measuring managerial effectiveness by four different methods.

    katedra: RSS; přílohy: cd; rozsah: 56Cílem této bakalářské práce je zjištění vlivu a určení nákladů na životní cyklus osobního automobilu a na jeho ekonomickou životnost a jak z těchto nákladů určit optimální dobu jeho náhrady. K určení optimální doby náhrady osobního automobilu byla zvolena metoda adverzního minima. Tato metoda umožňuje určit průměrné náklady za definovaná časová období. Dílčí období byla určena dvojím způsobem: časovými intervaly provozu automobilu bez ohledu na intenzitu provozu a intervaly stanovenými podle frekvence provozu (ujeté vzdálenosti). Předpokladem úspěšného řešení je získání a zpracování potřebných informací o zvolených automobilech. Výsledkem práce je analýza jednotlivých variant, tj. porovnání čtyř vybraných osobních automobilů od dvou výrobců a určení jejich optimální doby náhrady. Závěr práce tvoří porovnání výsledků jednotlivých automobilů.The aim of this bachelor thesis is to identify and determine the influence of life-cycle cost of a passenger car on its economic operating life and how these costs determine the optimal duration of compensation. To determine the optimal time for reimbursement of a car was chosen method of adverse minimum. This method allows determining the average cost for a defined time period. Sub-periods were determined in two ways, which is the time interval motor, regardless of the intensity and frequency of operation according to the frequency of operation (distance). Prerequisite for a successful solution is obtaining and processing all necessary information on selected cars. The outcome of this work is the analysis of the various options, i.e., comparing the four selected cars from two different manufacturers and to determining their optimal time for a refund. The conclusion consists of the comparison of the results of each car

    The study examines the relationship between a leader’s warmth, dominance and three different indicators of leader effectiveness in the environment of a four-month long Managerial Simulation Game. Data about 184 CEOs were gained via self-reports, from the results of the simulation game, and from 3,340 of their followers. Each CEO completed an Interpersonal Checklist (ICL) and was evaluated, on average, by 18 followers in terms of her leadership emergence and perceived leader effectiveness. Group performance was assessed based on the results of game companies. Neither leader warmth nor leader dominance correlated with any of the three indicators of leader’s effectiveness. The analysis of moderation effect however revealed a significant effect of interaction of leader warmth and dominance on group performance, perceived leader effectiveness, and leadership emergence. CEOs with greater warmth are less effective when possessing a low degree of dominance. On the contrary, the relationship between warmth and leader effectiveness is positive when the degree of dominance is high. An effective leader therefore has to be both warm and dominant. A low degree of dominance combined with excessive warmth might yield a counterproductive effect. The results of the study elucidate an underexplored relationship between leader warmth and effectiveness and illustrate the importance of examining various antecedents of leadership simultaneously.Studie se zabývá vlivem interpersonálních rysů leadera vztahovost a dominance na tři indikátory efektivity leadera v prostředí čtyři měsíce trvající manažerské simulační hry. Pro studii byla získána data z výsledků 184 podniků v simulační hře, ze sebehodnocení 184 generálních ředitelů těchto podniků a z hodnocení jejich 3 340 podřízených. Každý generální ředitel vyplnil Learyho interpersonální dotazník (ICL) a v průměru 18 podřízených hodnotilo jeho leadership emergence a vnímanou efektivitu. Objektivní výkon leaderem vedené skupiny byl posuzován na základě výsledků podniků v manažerské simulační hře. Vztahovost ani dominance nekorelovaly s žádným indikátorem efektivity leadera. Analýza interakce mezi vztahovostí a dominancí ale prokázala signifikantní moderační efekt dominance ve vztahu mezi vztahovostí a výkonem skupiny, vnímanou efektivitou leadera i leadership emergence. Více vztahoví leadeři jsou málo efektivní, pokud jsou zároveň i málo dominantní. Naopak při vysoké úrovni dominance je vztah mezi vztahovostí a efektivitou leadera pozitivní. Efektivní leader tedy musí být jak vztahový, tak dominantní. Naopak při nízké dominanci je přílišná vztahovost kontraproduktivní. Výsledky studie vysvětlují dosud nejasný vztah mezi vztahovostí a efektivitou leadera a ukazují na nutnost zkoumat faktory ovlivňující leadership ve vzájemném kontextu.The study examines the relationship between a leader’s warmth, dominance and three different indicators of leader effectiveness in the environment of a four-month long Managerial Simulation Game.

    This study explores the relationship between leadership effectiveness and generic and stable competencies. Task- related, people-related and self-related competencies were examined as predictors of leadership effectiveness as measured by four different criteria: group performance, leader effectiveness, leadership emergence and leadership self–efficacy. 134 top managers were evaluated by 2,482 subordinates after a four-month management simulation game. Task-related competencies were shown to be the best predictor of leadership effectiveness; they were a very strong predictor of leadership emergence, a strong predictor of leadership self–efficacy and perceived leadership effectiveness, medium strong predictor of group performance. People-related and self-related competencies weakly predicted leadership emergence. The results can be applied when selecting leaders for working groups that have short-term durations and do not require frequent personal contact.Studie se zaměřuje na vztah mezi efektivitou leadera a jeho stabilními generickými kompetencemi. Kompetence řešení problémů, vztahové kompetence a kompetence sebeřízení byly ověřovány jako prediktory efektivity leadershipu měřené čtyřmi různými ukazateli – objektivně měřeným výkonem skupiny, vnímanou efektivitou leadera, leadership emergence a leadership self–efficacy. Výzkum probíhal v prostředí tříměsíční manažerské simulační hry. Zúčastnilo se ho 134 leaderů a 2 446 následovníků, kteří leadery hodnotili. Všichni respondenti byli vysokoškolskými studenty. Nejlepším prediktorem efektivity leadera jsou kompetence řešení problémů, které jsou středně silným prediktorem výkonu skupiny, silným prediktorem vnímané efektivity leadera, velmi silným prediktorem leadership emergence a silným prediktorem leadership self–efficacy. Vztahové kompetence a kompetence sebeřízení predikují slabě pouze leadership emergence. Kompetenční model obecně nejlépe predikuje leadership emergence a nejhůře výkon skupiny. Výsledky lze využít při výběru leaderů pracovních týmů, které fungují krátkodobě, a vzájemná spolupráce nevyžaduje častý osobní kontakt.This study explores the relationship between leadership effectiveness and generic and stable competencies.
