A study on teamwork effectiveness of cross-functional teams

Tsai, Meng-chen 23 June 2010 (has links)
In these years, corporations have valued the cooperation among departments in their organizations. Team members from cross-functional teams composed of different functional areas have frequent communication due to the need for cooperation and support by each other. A well-performed team relies on effective communication and such interactive behavior between team members. These team members come from different departments or functions, which results in the variations in team members¡¦ standpoint and ways of doing things, but these make the teams more flexible and diversified. On the other hand, each department¡¦s sectionalism and patterns of behavior by usual practices cause the cross-functional teams¡¦ barrier of communication. Thus, this study applies the concept about the classification of teams raised by Larson & Frank (1989), and to study the issue of teamwork effectiveness of cross-functional teams through the qualitative interview method, and further to bring up conclusion and suggestion towards cross-functional teamwork. This study considers the inter-dependence between cross-functional team members, need for innovation of team¡¦s task, and organizational support as three dimensions to generalize the managerial implications in the respect of the performance of teamwork. In sum, under general conditions, ¡§the autonomy of teamwork¡¨ and ¡§the clarity of team¡¦s task¡¨ both could be coordinated to improve the performance of teamwork, however , ¡§the trust among team members¡¨ is both a necessary factor and basis to facilitate the communication and coordination in cross-functional teams and on which teams could work smoothly. Corporate culture and team leader would also influence communication among team members, therefore organization should build a free, open, and respectful communication environment. In addition, organization should empower team members with enough authority which helps team members exert their influence while communicating with other department. Besides, as a vital role of guiding, facilitating, and coordinating cross-department cooperation, the team leader boosts team¡¦s morale, provides decision-making support, and motivate team members to achieve team¡¦s goal. If necessary, team leaders should make good use of their ability of coordination to raise team members¡¦ coherence to their team, and further to help team members to reach an agreement.

A Study On Motivation, Attitude, Behavior And Advertising Effectiveness Of Internet Video Advertising Audiences

Chiang, Shou-Jie 05 July 2011 (has links)
In Taiwan, there is an increasing number of people using the Internet. Advertising firms have noticed the change in consumer behavior, and thus are investing a lot of money on online advertising. The biggest difference between advertising on televisions and advertising on the Internet is the¡ymotivation¡z. All of these video advertising will not only show on television. Video advertising audiences will gradually move to online video advertising. These are the findings from our research: 1.The motives of online audiences, their means of viewing the advertisement and the post-viewing actions are largely related to each other. Different motives also bring differences to the affected motives, attitudes, actions and the impact of the advertising. 2.Most of the time, advertisements that are interesting and humorous, have a storyline, or have valuable information are largely related to the attitudes of the consumers. 3.Consumers with positive attitudes would want to share the advertisements and their effects,whereas consumers with negative attitudes will not take any actions. Neither would the advertisement bring much of an impact. 4.When sharing the positive feedback, the viewers shared that the advertisements make a great impression on them. The advertisements also confirm whatever they know about the product. After that, branding of the product and the viewers¡¦willingness to buy the product are also factors. However, the research discovered that many of the interviewed subjects prefer television advertisements over online advertisements.

The Influence Of Endorser Credibility on Advertising Effectiveness¡ÐExemplified By P&G Inc.

Hung, Chun-chieh 13 March 2012 (has links)
According to the report of effective advertising analysis in the Taiwan area released by Rainmaker XKM International Corp., the advertising amount of care product industry is up to 28.8 million dollars, ranking second place in whole industry. In the market of care products, each firm is in high competition. For winning form the competition and accessing to consumer, the firms look for celebrities to be the endorsers for their own products, and even spend tons of money to make consumers know their products and brands in the short period. The strategies of endorser have many advantages, and be adopted widely. Besides, based on the properties that the care product industry is in high competition and the product life cycle is very short, whether the expenditure of spokesman can reach firm¡¦s expectation? Are the endorsers that firms choose are liked by public? This research takes Olay as example to discuss the effect of endorser credibility on advertising effectiveness. Also, this research takes involvement with advertisement as moderator variable to realize the relationship between endorser credibility and advertising effectiveness. Finally, comparing Olay¡¦s endorsers belong to different products to understand consumer¡¦s evaluation. The consequences of analysis indicate that the endorser credibility will affect advertising effectiveness and the trustworthiness, relevance, and likability has higher positive relationship. In addition to, the attractiveness and expertness has lower relationship. Besides, involvement with advertisement certainly has moderator effect between endorser credibility and advertising effectiveness. Finally, this research gives some practical advices for the business administrator according to the consequences of research.

The Influence of Spokesperson¡¦s Gender and Product Gender Image on Advertising Effectiveness

Fan, Ya-chi 21 June 2012 (has links)
¡@Nowadays, spokesperson is a very common advertising strategy. A good spokesperson can favorably attract customers¡¦ attention, produce better recall or precognition of a brand name, create an image for a product etc. In general, advertisers usually consider the fittingness between spokesperson¡¦s gender and product gender image. As gender roles and gender stereotype are changing, some product gender images are blurred as well. Therefore, some cross-over endorsements are emerged (an advertising is targeting a nontraditional user in terms of gender). Past researches have shown that the relationship between spokesperson¡¦s gender and product gender image is inconsistent. Hence, this study focuses on products with ¡§Masculine Image¡¨ and classified products based on FCB Model, exploring how different products types and customers¡¦ gender influence gender endorsement on advertising effectiveness. ¡@The present study uses experimental design to investiage the effects of two types of gender endorsement and four product categories on advertising effectiveness. A 2x4 between-subject design is conducted. All eight scenarios are made through fictional ads, and the advertising effectiveness is measured by attitude toward the ad (AD), attitude toward the product (AP) and purchase intention (PI). ¡@The findings of this study indicate that AD and PI are more favorable when the product¡¦s gender image and spokesperson¡¦s gender are consistent. The interaction between product types and gender endorsement advertisement exits especially in the effective product. Spokespersons¡¦ gender is an effective promotional cue in influencing customers¡¦ perceptions of the gender image of products on the self-satisfaction product. Meanwhile, this study also finds there is no interaction between the gender endorsement advertisement and customer¡¦s gender.

The Effect of Female Leaders¡¦ Personality Traits and Leadership Styles on the Leadership Effectiveness- Exemplified by Southern Electronic Media Centers

Chung, Yun-yen 03 September 2012 (has links)
In recent years, our society changes rapidly. The position of females in Taiwan have been promoted significantly. The situation induces the raise of the awakening of feminist consciousness. After that, females gets more opportunities to show off all of their talents, and generally become managers or leaders at workplace. The phenomenon caused many discussions and researches, and really highlights the importance of the topic of today's female leaders. How a leader shows the leadership performance could decide the success of the organizational development. Also, we know through the relevant literature that a leader¡¦s personality traits and leadership styles are not only an important issue in the organizational behavior study, but also the key elements of leadership effectiveness. Therefore, the purpose of this study is to inquire the relationship among female leaders¡¦ personality traits, leadership styles and leadership effectiveness by the subordinates cognition in southern electronic media centers. The questionnaire of the study is divided into two parts: the leader questionnaire and the subordinate questionnaire. Total of 215 out of 250 questionnaires were returned. (There are 38 out of 40 from leader questionnaires, and 177 out of 200 from subordinate questionnaires.) The data are analyzed by a variety of statistical methods, such as descriptive statistic, factor analysis, reliability analysis, and regression analysis, etc. The statistical analyses had concluded as followed¡G 1. The hypothesis that the female leaders¡¦ personality traits are significant effect on their leadership effectiveness is partially supported. In accordance with the order of the influence on leadership effectiveness, ¡§Conscientiousness¡¨, ¡§Agreeableness¡¨, and ¡§Openness to Experience¡¨ are the main significantly indicators to predict leadership effectiveness. 2. The hypothesis that the female leaders¡¦ leadership styles are significant effect on their leadership effectiveness is partially supported. ¡§Consideration¡¨is the only significantly indicators to predict leadership effectiveness. 3. Consider the female leaders¡¦ personality traits and the leadership styles at the same time, ¡§Conscientiousness * Initiating Structure¡¨ and ¡§Emotional Stability * Consideration¡¨ have a significant effect on the leadership effectiveness. Thus, the leadership styles have mediator effects between the personality traits and leadership effectiveness.

Film Cooling, Heat Transfer and Aerodynamic Measurements in a Three Stage Research Gas Turbine

Suryanarayanan, Arun 2009 May 1900 (has links)
The existing 3-stage turbine research facility at the Turbomachinery Performance and Flow Research Laboratory (TPFL), Texas A and M University, is re-designed and newly installed to enable coolant gas injection on the first stage rotor platform to study the effects of rotation on film cooling and heat transfer. Pressure and temperature sensitive paint techniques are used to measure film cooling effectiveness and heat transfer on the rotor platform respectively. Experiments are conducted at three turbine rotational speeds namely, 2400rpm, 2550rpm and 3000rpm. Interstage aerodynamic measurements with miniature five hole probes are also acquired at these speeds. The aerodynamic data characterizes the flow along the first stage rotor exit, second stage stator exit and second stage rotor exit. For each rotor speed, film cooling effectiveness is determined on the first stage rotor platform for upstream stator-rotor gap ejection, downstream discrete hole ejection and a combination of upstream gap and downstream hole ejection. Upstream coolant ejection experiments are conducted for coolant to mainstream mass flow ratios of MFR=0.5%, 1.0%, 1.5% and 2.0% and downstream discrete hole injection tests corresponding to average hole blowing ratios of M = 0.5, 0.75, 1.0, 1.25, 1.5, 1.75 and 2.0 for each turbine speed. To provide a complete picture of hub cooling under rotating conditions, experiments with simultaneous injection of coolant gas through upstream and downstream injection are conducted for an of MFR=1% and Mholes=0.75, 1.0 and 1.25 for the three turbine speeds. Heat transfer coefficients are determined on the rotor platform for similar upstream and downstream coolant injection. Rotation is found to significantly affect the distribution of coolant on the platform. The measured effectiveness magnitudes are lower than that obtained with numerical simulations. Coolant streams from both upstream and downstream injection orient themselves towards the blade suction side. Passage vortex cuts-off the coolant film for the lower MFR for upstream injection. As the MFR increases, the passage vortex effects are diminished. Effectiveness was maximum when Mholes was closer to one as the coolant ejection velocity is approximately equal to the mainstream relative velocity for this blowing ratio. Heat transfer coefficient and film cooling effectiveness increase with increasing rotational speed for upstream rotor stator gap injection while for downstream hole injection the maximum effectiveness and heat transfer coefficients occur at the reference speed of 2550rpm.

Experimental Study of Gas Turbine Blade Film Cooling and Heat Transfer

Narzary, Diganta P. 2009 August 1900 (has links)
Modern gas turbine engines require higher turbine-entry gas temperature to improve their thermal efficiency and thereby their performance. A major accompanying concern is the heat-up of the turbine components which are already subject to high thermal and mechanical stresses. This heat-up can be reduced by: (i) applying thermal barrier coating (TBC) on the surface, and (ii) providing coolant to the surface by injecting secondary air discharged from the compressor. However, as the bleeding off of compressor discharge air exacts a penalty on engine performance, the cooling functions must be accomplished with the smallest possible secondary air injection. This necessitates a detailed and systematic study of the various flow and geometrical parameters that may have a bearing on the cooling pattern. In the present study, experiments were performed in three regions of a non-rotating gas turbine blade cascade: blade platform, blade span, and blade tip. The blade platform and blade span studies were carried out on a high pressure turbine rotor blade cascade in medium flow conditions. Film-cooling effectiveness or degree of cooling was assessed in terms of cooling hole geometry, blowing ratio, freestream turbulence, coolant-to-mainstream density ratio, purge flow rate, upstream vortex for blade platform cooling and blowing ratio, and upstream vortex for blade span cooling. The blade tip study was performed in a blow-down flow loop in a transonic flow environment. The degree of cooling was assessed in terms of blowing ratio and tip clearance. Limited heat transfer coefficient measurements were also carried out. Mainstream pressure loss was also measured for blade platform and blade tip film-cooling with the help of pitot-static probes. The pressure sensitive paint (PSP) and temperature sensitive paint (TSP) techniques were used for measuring film-cooling effectiveness whereas for heat transfer coefficient measurement, temperature sensitive paint (TSP) technique was employed. Results indicated that the blade platform cooling requires a combination of upstream purge flow and downstream discrete film-cooling holes to cool the entire platform. The shaped cooling holes provided wider film coverage and higher film-cooling effectiveness than the cylindrical holes while also creating lesser mainstream pressure losses. Higher coolant-to-mainstream density ratio resulted in higher effectiveness levels from the cooling holes. On the blade span, at any given blowing ratio, the suction side showed better coolant coverage than the pressure side even though the former had two fewer rows of holes. Film-cooling effectiveness increased with blowing ratio on both sides of the blade. Whereas the pressure side effectiveness continued to increase with blowing ratio, the increase in suction side effectiveness slowed down at higher blowing ratios (M=0.9 and 1.2). Upstream wake had a detrimental effect on film coverage. 0% and 25% wake phase positions significantly decreased film-cooling effectiveness magnitude. Comparison between the compound shaped hole and the compound cylindrical hole design showed higher effectiveness values for shaped holes on the suction side. The cylindrical holes performed marginally better in the curved portion of the pressure side. Finally, the concept tip proved to be better than the baseline tip in terms of reducing mainstream flow leakage and mainstream pressure loss. The film-cooling effectiveness on the concept blade increased with increasing blowing ratio and tip gap. However, the film-coverage on the leading tip portion was almost negligible.
