How firms compete for an advantage is among the most critical questions in Business Strategy. While several researchers link executives to key strategic outcomes, much less is understood on how the Upper-Echelon team drives the actual competitive behavior of the firm, which is manifested in the launching of observable and purposeful competitive actions within the marketplace. Considering that competitive behavior research tends to overlook the importance of human assets, in general, and executive human assets, in particular, I explore how the knowledge, skills, and abilities of the Chief Executive (CEO), Top Management Team (TMT), and Board of Directors (BOD) impact a firm's competitive behavior. In addition, I examine how sources of Social Capital, or the relationships between these Upper-Echelon actors, influence a firm's competitive behavior. Moreover, I argue and test for the moderating influence of executive compensation on firm competitive behavior. Applying relational demography to capture Human Capital and sources of Social Capital within the U.S. Pharmaceutical Industry, I find some empirical support that executives do, indeed, affect firm competitive behavior. Overall, the empirical evidence indicates that the Human Capital of the CEO, TMT, and BOD can influence all dimensions of a firm's Competitive Intensity. Unexpectedly and, contrary to prediction, executive dissimilarity (not similarity) tended to greatly influence a firm's Competitive Activity and Repertoire Complexity. Also, the moderating impact of executive bonus and incentive pay was largely supported. This dissertation contributes to both the competitive behavior and Upper-Echelon literatures. Notably, this dissertation adds to the very limited work that attempts to theoretically link and empirically test for executive impact on firm competitive behavior. By so doing, it begins to open the "black box" on how human assets at the Upper Echelon affect strategic outcomes through a firm's competitive behavior. / Ph. D.

數位時代孕育大數據技術的發展並帶動產業的創新，使用者數據的運用也日益活躍於商業領域，並分別為消費者與事業帶來便利的生活與競爭優勢。然而蒐集、處理、運用等數據價值鏈活動對於市場競爭造成相當的影響，也成為事業為反競爭行為的誘因，而引起競爭法的關注，多國競爭執法機關亦已陸續展開調查或進行相關研究。由於使用者數據涉及個人資訊隱私，更因其係產業創新的動力之一，從而競爭法管制的合適性與必要性一直為爭議性議題，後續延伸出對於現有競爭法架構的相容性疑義。本文透過文獻與案例分析，從使用者數據的特色出發，探討使用者數據於競爭法框架下之爭議，包含與隱私法規的競合問題及衝擊現行制度之因應方式。基於競爭法適度管制的觀點，提出可能評估市場力量的方式與使用者數據可能形成的限制競爭或不公平競爭之風險類型。冀望對於我國公平交易法就此議題之剖析與因應有所助益，迎接數據經濟的浪潮。 / Big data analytics technology evolves rapidly and enhances the pace of the innovation of industries in the digital era. Utilizing user data, which is a sort of valuable assets, becomes more popular in business. The new technology brings consumers fitted products and convenience and creates competitive advantages to firms. However, collecting, processing and analyzing large sets of user data not only benefit the entities in the market but also impact market competition. Competition agencies around the world have engaged in related investigations and research on data and competition. The mainly concerns are whether the amount of user data may build a barrier to entry, and whether firms which control user data in a massive amount or essential to competition may have incentives to abuse their market power to foreclose marker. Moreover, because user data is one factor of fostering innovation and has a strong correlation with privacy, the suitability and the necessity of competition law to regulate data issue is still controversial. If competition law intervenes, we should further consider how to adapt it to the present regulation. By reviewing academic literature and practical cases, this thesis begins with the introduction of characteristics of user data, followed by the analysis of the controversy concerning user data under the framework of competition law, including the trade-off between it and privacy laws and possible adjustment to the present framework. This paper also discusses the way to assess market power and specific types of anticompetitive and unfair competition behaviors. Finally, this thesis concludes with a short remark. Hopefully it can provide some references for further discussion on this issue under the Fair Trade Act in Taiwan.

Perceived organisational support and organisational commitment plays a vital role in determining turnover intention. When employees feel that their organisation supports them levels of commitment can increase. Thus, employees feel more obligated because of favourable benefits such as organisational effectiveness and reduced turnover. The purpose of the present study was to investigate the effect perceived organisational support and organisational commitment have on turnover intention. The study followed a descriptive survey method. A questionnaire, measured on a Likert Scale was used to collect data from respondents. The sample comprised 98 academic staff at the University of Fort Hare and the response rate was 56.6 percent. The results indicated that perceived organisational support and organisational commitment are negatively and significantly related to turnover intention. The study also revealed perceived organisational support and organisational commitment on turnover intention did not account for a higher variance when put together, however moderate variance was found. Perceived organisational support in this study was identified as the most effective predictor of turnover intention. In addition to managerial implications and limitations of the study, direction for future research is also suggested at the end of this study. The findings of this study will help in terms of understanding the state of organisational commitment of academics and its relationship with their intentions to leave.

<p>Ispitivanu grupu činilo je 1247 ispitanika sa povredama prednje ukr&scaron;tene veze kolena koji su operativno lečeni u periodu 2012.-2017. godina na Klinici za ortopedsku hirurgiju i traumatologiju Kliničkog centra Vojvodine. Ciljevi istraživanja bili su utvrđivanje uticaja nivoa sportske aktivnosti i mehanizama povređivanja na nastanak povreda prednje ukr&scaron;tene veze kolena, zatim uticaj spolja&scaron;njih faktora rizika (vrsta sporta, rang takmičenja, vrsta podloge, trening ili utakmica, period treninga) na nastanak povreda prednje ukr&scaron;tene veze kolena, odnosno uticaj unutra&scaron;njih faktora rizika (pol, starost, BMI) na nastanak povreda ove strukture kolena. Od ukupnog broja ispitanika njih 517 (41,5%) su činili aktivni sportisti, a 730 (58,5%) rekreativci. Značajnu većinu u posmatranom uzorku su činili mu&scaron;karci (82,6%), osobe starosti od 16 do 25 godina (62,6%) i normalno uhranjenje osobe (62%). Do povrede prednje ukr&scaron;tene veze do&scaron;lo je kod njih 504 (40,5%) prilikom aktivnog bavljenja sportom, dok su se povrede prilikom rekreativnog bavljenja sportom dogodile kod 741 ispitanika (59,5%). Među aktivnim sportistima, vi&scaron;e od dve trećine se takmičilo na internacionalnom ili republičkom nivou, odnosno u najvi&scaron;im rangovima takmičenja. Kontaktnim kolektivnim sportovima (fudbal, ko&scaron;arka i rukomet) bavilo se 77,9% ispitanika. Nekontaktnim sportovima kao &scaron;to su odbojka, borilački sportovi i skijanje bavilo se 22,1% ispitanika, pri čemu je najveći broj povreda nastao prilikom igranja fudbala (51,3%). Statistički značajno vi&scaron;e povreda (i prilikom aktivnog i prilikom rekreativnog bavljenja sportom) je nastalo bez direktnog kontakta (nekontaktne povrede koje su činile 78,7% povreda), pri čemu je najveći broj povreda nastao usled promene pravca i ritma kretanja. Kod aktivnih sportista najvi&scaron;e povreda dogodilo se na utakmicama (73,8%), slede povrede na treningu (24,1%), dok se na rekreaciji povredilo svega 2,1% ispitanika. Značajno vi&scaron;e povreda dogodilo se na sredini bavljenja sportskom aktivno&scaron;ću (47,4%) u odnosu na povrede na zagrevanju, početku, odnosno kraju sportske aktivnosti. Povrede su značajno če&scaron;će nastajale na travi (42%) i parketu (28%), nego na drugim vrstama podloge. Najveći broj ispitanika povredio se noseći patike prilikom bavljenja sportskom aktivno&scaron;ću. Postoje značajne razlike u kontekstu povređivanja u zavisnosti od pola ispitanika. Žene su u značajno većem procentu povređivane prikom aktivnog bavljenja sportom, dok su se mu&scaron;karci če&scaron;će povređivali na rekreaciji. Žene su se najče&scaron;će povređivale na rukometu, mu&scaron;karci na fudbalu. U odnosu na mu&scaron;karce, kod žena su povrede znatno ređe nastajale prilikom direktnog kontakta, a kad je u pitanju mesto povređivanja, žene su se če&scaron;će nego mu&scaron;karci povređivale na treningu. Preko 50% žena je povređeno na parketu, dok se najveći broj mu&scaron;karaca povredio na travi. Ispitanici sa prekomernom telesnom masom značajno če&scaron;će su se povređivali prilikom rekreacije, dok su se normalno uhranjeni če&scaron;će povređivali prilikom aktivnog bavljenja sportom. Faktori rizika za nastanak povreda prednje ukr&scaron;tene veze su brojni i specifični, odnosno da za svaku populacionu kategoriju postoje rizici, ali se uočava da su u svim sportovima, na svim podlogama i kod svih ispitanika povrede najče&scaron;će nastajale nekontaknim mehanizmom povređivanja. Formiranjem registra povređenih omogućilo bi se bolje razumevanje faktora rizika i njihovog međusobnog uticaja, kao i definisanje profila osoba pod najvećim rizikom za nastanak povrede prednje ukr&scaron;ene veze kolena. Na taj način obezbedile bi se potrebne informacije za planiranje preventivnih programa usmerenih na smanjenje rizika od povređivanja i omogućilo bi se sprovođenje odgovarajućih mera selektivne prevencije.</p> / <p>The study group consisted of 1247 respondents with anterior cruciate ligament injuries who were surgically treated in the period 2012-2017. at the Clinic for Orthopedic Surgery and Traumatology of the Clinical Center of Vojvodina. The objectives of the study were to determine the impact of sports activity levels and injury mechanisms on the occurrence of anterior cruciate ligament injuries, then the impact of external risk factors (type of sport, competition rank, type of surface, training or match, training period) on the occurrence of anterior cruciate ligament injuries and the influence of internal risk factors (gender, age, BMI) on the occurrence of injuries of this knee structure. Out of the total number of respondents 517 (41.5%) were active athletes, and 730 (58.5%) were recreational athletes. A significant majority in the observed group were men (82.6%), persons aged 16 to 25 years (62.6%) and normal BMI respondents (62%). Anterior cruciate ligament injury occurred in 504 of them (40.5%) during active sports, while injuries during recreational sports occurred in 741 respondents (59.5%). Among active athletes, more than two thirds competed at the international or national level- in the highest ranks of the competition. Contact collective sports (football, basketball and handball) were practiced by 77.9% of respondents. 22.1% of respondents practiced non-contact sports such as volleyball, martial arts sports and skiing. The largest number of injuries occurring while playing football (51.3%). Statistically significantly more injuries (both during active and recreational sports) occurred without direct contact (noncontact injuries-78,7% of total injuries number), with the largest number of injuries caused by changes in the direction and rhythm of movement. Among active athletes, most injuries occurred in matches (73.8%), followed by injuries in training (24.1%), while only 2.1% of respondents were injured in recreation. Significantly more injuries occurred in the middle of engaging in sports activity (47.4%) compared to injuries during the warm-up, beginning and end of sports activity. Injuries occurred significantly more often on grass (42%) and floor (28%) than on other types of surfaces. Most of the respondents were injured wearing sneakers while doing sports. There are significant differences in the context of injury depending on the gender of the respondents. A significantly higher percentage of women were injured during active sports, while men were more often injured during recreational sport activities. Women were most often injured in handball, men in football. Compared to men, injuries were much less common in women during direct contact, and when it comes to the place of injury, women were injured more often than men during training acitivities. Over 50% of women were injured on the floor, while the largest number of men were injured on the grass. Subjects with overweight were significantly more likely to be injured during recreational sport acitivites, while those with normal BMI were more likely to be injured during active sports. Risk factors for anterior cruciate ligament injuries are numerous and specific and there are risks for each population category, but it is noticed that in all sports, on all surfaces and in all subjects, injuries were most often caused by a noncontact injury mechanism. The formation of a Register of injuries would enable a better understanding of risk factors and their mutual influence, as well as the definition of the profile of persons at greatest risk for the occurrence of an anterior cruciate ligament injury. This would provide the necessary information for planning prevention programs aimed at reducing the risk of injury and would enable the implementation of appropriate selective prevention measures.</p>
