Title: The Impact of Social Media on Consumer Behavior: A Study on Generation Z
Abstract:
This thesis aims to examine the impact of social media on consumer behavior, specifically focusing on Generation Z. With the rapid growth of social media platforms, it has become crucial for businesses to understand how these platforms influence the buying decisions of the younger generation. The study employs a mixed-method research design, combining quantitative surveys with qualitative interviews to obtain comprehensive insights.
The quantitative survey was conducted among a sample of 500 Generation Z consumers, aged between 18 and 24 years old. The survey questionnaire consisted of Likert-scale questions, exploring various dimensions such as social media usage, engagement with brands, purchase decision-making process, and brand loyalty. The findings revealed that social media plays a significant role in shaping the attitudes and behavior of Generation Z consumers.
Furthermore, in-depth interviews were conducted with a subset of survey participants to gain a deeper understanding of their experiences and perceptions. The interviews revealed that social media platforms act as a source of inspiration, information, and social validation for Generation Z consumers. They heavily rely on user-generated content, online reviews, and recommendations from influencers before making a purchase decision. Moreover, social media platforms have become an integral part of their social identity, where they interact with brands, seek entertainment, and express their opinions.
The results of this study have important implications for marketers and brand managers. It is crucial for businesses to have a strong presence on social media platforms and engage with Generation Z consumers effectively. Brands need to create authentic and relatable content, collaborate with influencers, and actively participate in online conversations to establish a connection with this generation. Moreover, understanding the factors that drive brand loyalty among Generation Z is essential for long-term success.
In conclusion, this study provides valuable insights into the impact of social media on consumer behavior among Generation Z. The findings emphasize the importance of social media platforms as a key influencer in the purchase decision-making process. Businesses need to adapt their marketing strategies to effectively engage with this generation and build brand loyalty.
Keywords: social media, consumer behavior, Generation Z, brand engagement, purchase decision-making, brand loyalty

Title: The Role of Emotional Intelligence in Leadership Effectiveness: A Comparative Study of Public and Private Sector Organizations
Abstract:
This thesis investigates the role of emotional intelligence (EI) in leadership effectiveness, with a comparative analysis between public and private sector organizations. Emotional intelligence has gained significant attention in recent years as a critical factor in effective leadership. The study aims to explore whether emotional intelligence plays a different role in leadership effectiveness in the two sectors.
The research adopts a quantitative approach, utilizing a structured questionnaire to collect data from leaders in both public and private sector organizations. The questionnaire measures emotional intelligence using the Emotional Intelligence Appraisal tool developed by Bradberry and Greaves (2005). Leadership effectiveness is assessed through self-evaluation and subordinate ratings, using the Multifactor Leadership Questionnaire (MLQ) developed by Bass and Avolio (1995).
The results indicate that emotional intelligence significantly contributes to leadership effectiveness in both public and private sector organizations. However, the study reveals some differences in the specific dimensions of emotional intelligence that are more influential in each sector. In the public sector, self-awareness and social skills are found to be more critical for effective leadership. On the other hand, in the private sector, self-management and relationship management are identified as key dimensions for leadership effectiveness.
Furthermore, the study examines the impact of contextual factors, such as organizational culture and leadership style, on the relationship between emotional intelligence and leadership effectiveness. The findings suggest that while emotional intelligence is important, its impact can be influenced by the organizational context. Different leadership styles and organizational cultures may enhance or diminish the effects of emotional intelligence on leadership effectiveness.
The findings of this study have practical implications for organizations in both sectors. Public sector organizations can focus on developing self-awareness and social skills among their leaders to enhance their effectiveness. Private sector organizations, on the other hand, should emphasize self-management and relationship management to improve leadership effectiveness. Understanding the influence of organizational culture and leadership style can also help organizations create an environment that supports the application of emotional intelligence in leadership.
In conclusion, this study highlights the significance of emotional intelligence in leadership effectiveness, with variations between public and private sector organizations. Emphasizing the development of emotional intelligence skills can contribute to improved leadership performance in both sectors, but the specific dimensions of emotional intelligence may vary. Organizations need to consider the contextual factors that influence the relationship between emotional intelligence and leadership effectiveness.
Keywords: emotional intelligence, leadership effectiveness, public sector, private sector, organizational culture, leadership style

Studies on Defence Gene-Myrosinase Gene from Cruciferae Vegetable
ABSTRACT
Glucosinolates-myrosinase is an important defence system in brassica of cruciferous vegetables, also referred to as “the mustard oil bomb”。The myrosinase genes in 49 Brassica parachinensis Bailey、Brassica oleracea L. Var. capitata (L.) and Brassica aboglabra Baily were cloned and analyzed in this paper.
Three methods of RNA extraction were compared and the results showed that the methods of Phenol-Chloroform and Trizol were better than the method of UNIQ-10. The abundance of RNA in cruciferous vegetable was also related to the attacks from different insects.
Specific primers based on the the conservative domain of myrosinasewere designed to clone myrosinase genes in 49 Brassica parachinensis Bailey, Brassica oleracea L. Var. capitata (L.) and Brassica aboglabra Baily by RT-PCR.
One nucleotide acid fragment (350bp) was obtained in Brassica parachinensis Bailey and Brassica oleracea L. Var. capitata (L.) respectively, but two fragments (350bp and 466bp) in Brassica aboglabra Baily.
It was found that that the fragments of 350bp were highly homologous with the cloned myrosinase genes in Genbank. Therefore, these fragments of 350bp were part of myrosinase genes in these plants. The fragment of 466bp in Brassica aboglabra Baily had an additional nucleotide acid between 310 and 426 compared with myrosinase genes in Genbank. Amino acid sequences were deduced from these fragments and analyzed.
Primers for RACE were designed based on the nucleotide acid sequences of the fragment that has been cloned in Brassica parachinensis Bailey to gain the full gene of myrosinase (full cDNA). The full myrosinase gene is of 1841bp with an open reading frame of 1647bp. The secondary structure of myrosinase mRNA was predicted with 83 loops that affect the stability of mRNA and the least structure energyof
-33.61kcal.
The protein sequence of 548 amino acids was deduced from this gene. This protein was predicted to be a hydrophilic and dissoluble protein according to the hydrophobicity analyse.
The secondary structure of the protein was predicted to have 149 amino acids (27.2%)as alpha helixes (Hh), 79 amino acids (14.4%) as beta sheets (Ee), 281 amino acids (51.3%) as random coils (Cc), and 39 amino acids (7.1%) with unknown stuctures(?)。
The myrosinases in Brassica parachinensis Bailey、Brassica oleracea L. var. capitata (L.) and Brassica aboglabra Baily were found to have a very close relationship through the cluster analyses based on the amino acid sequences.
Key words: myrosinase; RNA extraction; RACE; cruciferal vegetable; Phyllotreta striolata (Fabricius); Plutella xylostella

Information Granulation Method of Temporal Data and Applications
ABSTRACT
In 1965, the famous American computer and control specialist Professor Lotfi A.Zadeh proposed the concept of fuzzy sets, creating a new field of mathematics--fuzzy math. In 1979, Professor Zadeh proposed the concept of information granules, studying a group of similar subjects as a whole or a whole as a part.
