Description
Mobile applications (Apps) markets with App stores have introduced a new approach to define and sell software applications with access to a large body of heterogeneous consumer population. Several distinctive features of mobile App store markets including – (a) highly heterogeneous consumer preferences and values, (b) high consumer cognitive burden of searching a large selection of similar Apps, and (c) continuously updateable product features and price – present a unique opportunity for IS researchers to investigate theoretically motivated research questions in this area. The aim of this dissertation research is to investigate the key determinants of mobile Apps success in App store markets. The dissertation is organized into three distinct and related studies. First, using the key tenets of product portfolio management theory and theory of economies of scope, this study empirically investigates how sellers’ App portfolio strategies are associated with sales performance over time. Second, the sale performance impacts of App product cues, generated from App product descriptions and offered from market formats, are examined using the theories of market signaling and cue utilization. Third, the role of App updates in stimulating consumer demands in the presence of strong ranking effects is appraised. The findings of this dissertation work highlight the impacts of sellers’ App assortment, strategic product description formulation, and long-term App management with price/feature updates on success in App market. The dissertation studies make key contributions to the IS literature by highlighting three key managerially and theoretically important findings related to mobile Apps: (1) diversification across selling categories is a key driver of high survival probability in the top charts, (2) product cues strategically presented in the descriptions have complementary relationships with market cues in influencing App sales, and (3) continuous quality improvements have long-term effects on App success in the presence of strong ranking effects.

Description
By collecting and analyzing more than two million tweets, U.S. House Representatives’ voting records in 111th and 113th Congress, and data from other resources I study several aspects of adoption and use of Twitter by Representatives. In the first chapter, I study the overall impact of Twitter use by Representatives on their political orientation and their political alignment with their constituents. The findings show that Representatives who adopted Twitter moved closer to their constituents in terms of political orientation.
By using supervised machine learning and text mining techniques, I shift the focus to synthesizing the actual content shared by Representatives on Twitter to evaluate their effects on Representatives’ political polarization in the second chapter. I found support for the effects of repeated expressions and peer influence in Representatives’ political polarization.
Last but not least, by employing a recently developed dynamic network model (separable temporal exponential-family random graph model), I study the effects of homophily on formation and dissolution of Representatives’ Twitter communications in the third chapter. The results signal the presence of demographic homophily and value homophily in Representatives’ Twitter communications networks.
These three studies altogether provide a comprehensive picture about the overall consequences and dynamics of use of online social networking platforms by Representatives.

Description
The recent changes in the software markets gave users an unprecedented number
of alternatives for any given task. In such a competitive environment, it is imperative
to understand what drives user behavior. To that end, the research presented in
this dissertation, tries to uncover the impact of business strategies often used in the
software markets.
The dissertation is organized into three distinct studies into user choice and post
choice use of software. First using social judgment theory as foundation, zero price
strategies effects on user choice is investigated, with respect to product features,
consumer characteristics, and context effects. Second, role of social features in
moderating network effects on user choice is studied. And finally, the role of social
features on the effectiveness of add-on content strategy on continued user engagement
is investigated.
The findings of this dissertation highlight the alignments between popular business
strategies and broad software context. The dissertation contributes to the litera-
ture by uncovering hitherto overlooked complementarities between business strategy
and product features: (1) zero price strategy enhances utilitarian features but not
non-utilitarian features in software choice, (2) social features only enhance network
externalities but not social influence in user choice, (3) social features enhance the
effect of add-on content strategy in extending software engagement.

Description区块链技术应用（DApp）最早出现在数字货币交易上，也有部分DApp涉及游戏、音乐、教育、出行等场景，但是由于前几年DApp还属于新生事物，多数社会大众对其了解程度不高，加之多数DApp开发和优化的水平有限，用户体验较差，因此并没有良好的市场表现。
尽管如此， 2017年11月一款叫CryptoKitties的区块链游戏正式上线，并且在短时间之内引爆了整个区块链，游戏交易量在1个月内暴涨至1.7万。随后风险资本不断进入区块链行业，并且催生出一大批区块链DApp出来，涉及的应用场景进一步拓展到游戏、赌博、社交、金融、市场、保险、健康等领域。如何设计一套有效的治理机制，从而实现用户留存高、项目前景好，成为多数区块链DApp最为关注的问题。
本文选择CryptoKitties、Mycryptohero、Steemit和NeoWorld这四款区块链DApp作为案例研究对象，通过归纳总结发现这四款DApp都将游戏性、通证经济、社群生态和网络效应作为共同的治理方式。基于这四方面，本文对四款DApp的异同进行了跨案例比较，发现NeoWorld要比其他三款DApp在治理手段上更加丰富和合理。最后，利用136份NeoWorld玩家调查问卷数据，对游戏性、通证经济、社群生态和网络效应对其治理绩效的影响进行了实证检验，结果发现除了社群生态之外，其他三个因素都能提升NeoWorld的治理绩效。
本研究的最大创新是选择在区块链场景应用中具有代表性的4个DApp项目作为案例研究对象，通过归纳总结发现各自在治理手段上的共同之处（影响因素），并根据问卷调查数据对不同影响因素对特定Dapp治理绩效的影响程度进行实证检验，丰富了平台治理相关研究成果，也为社会各界深化认识DApp治理方式和成效，推动DApp行业生态健康有序发展提供参考和借鉴。

Description随着科创板、注册制出台，企业间的竞争逐步从资源型竞争转向科技和技术的竞争，大量有知识、有文化、有理想、有技术的人才涌入社会，给科技发展、技术创新在政策、市场和人才层面提供了支撑、机遇和源动力，科技型创新企业大量涌现，形成趋势性上升行业。科技型创业企业多冠以“规模小、技术密集、高成长、高风险”的标签，在融资过程中困难重重，这些特点与风险投资（VC）“高风险、高回报”的特质不谋而合，VC机构还能给被投企业提供人才、信息、商业模式、政策法律咨询等增值服务，助力企业发展。引入VC走上市路径成为诸多科技型创业企业最优选择。
近些年VC行业在我国得到迅猛发展，IVC和CVC已成了助推我国科技型创业企业发展的主力军。由于IVC和CVC的组织架构、投资期限、资金来源、投资目标、投资经验、管理层薪资结构等方面存在着很大的不同。不同的投资模式势必会对被投企业的经营活动产生不同影响，本文基于总资产单位产出和投入为经济学逻辑，针对相关变量提出假设。
本文对我国中小板和创业板2013年以前上市的七个高新技术行业（5G通信、大数据、人工智能、软件服务、生物制药、新材料、医疗器械）共123家，以上市为起点的6年企业数据为基础。以IVC和CVC为自变量，以上市司龄、企业规模、行业控制、分红占净利润比为控制变量，以V/A、E/A、K/A和E/R为因变量，对IVC和CVC投入的科技型创业企业分别进行描述性统计、相关性分析和回归分析，验证IVC和CVC对被投企业的市场维度（V/A）、财务维度（E/A、E/R）、创新维度（K/A）的影响。试图从企业的角度出发，理清企业与VC的关系，为二级市场投资者提供一个投资决策视角。
