Description
Forrest Research estimated that revenues derived from mobile devices will grow at an annual rate of 39% to reach $31 billion by 2016. With the tremendous market growth, mobile banking, mobile marketing, and mobile retailing have been recently introduced to satisfy customer needs. Academic and practical articles have widely discussed unique features of m-commerce. For instance, hardware constraints such as small screens have led to the discussion of tradeoff between usability and mobility. Needs for personalization and entertainment foster the development of new mobile data services. Given distinct features of mobile data services, existing empirical literature on m-commerce is mostly from the consumer side and focuses on consumer perceptions toward these features and their adoption intentions. From the supply side, limited data availability in early years explains the lack of firm-level studies on m-commerce. Prior studies have shown that unclear market demand is a major reason that hinders firms' adoption of m-commerce. Given the advances of smart phones, especially the introduction of the iPhone in 2007, firms recently have started to incorporate various mobile information systems in their business operations. The study uses mobile retailing as the context and empirically assesses firms' migration to this new sales venue with a unique cross-sectional dataset. Despite the distinct features of m-commerce, m-Retailing is essentially an extended arm of e-Retailing. Thus, a dependency perspective is used to explore the link between a firm's e-Retail characteristics and the migration to m-Retailing. Rooted in the innovation diffusion theory, the first stage of my study assesses the decision of adoption that indicates whether a firm moves to m-Retailing and the extent of adoption that shows a firm's commitment to m-Retailing in terms of system implementation choices. In this first stage, I take a dependency perspective to examine the impacts of e-Retail characteristics on m-Retailing adoption. The second stage of my study analyzes conditions that affect business value of the m-Retail channel. I examine the association between system implementation choices and m-Retail performance while analyzing the effects of e-Retail characteristics on value realization. The two-stage analysis provides an exploratory assessment of firm's migration from e-Retailing to m-Retailing.

Description
In accordance with the Principal Agent Theory, Property Right Theory, Incentive Theory, and Human Capital Theory, firms face agency problems due to “separation of ownership and management”, which call for effective corporate governance. Ownership structure is a core element of the corporate governance. The differences in ownership structures thus may result in differential incentives in governance through the selection of senior management and in the design of senior management compensation system. This thesis investigates four firms with four different types of ownership structures: a public listed firm with the controlling interest by the state, a public listed firm with a non-state-owned controlling interest, a public listed firm a family-owned controlling interest, and a Sino-foreign joint venture firm. By using a case study approach, I focus on two dimensions of ownership structure characteristics – ownership diversification and differences in property rights so as to document whether there are systematic differences in governance participation and executive compensation design. Specifically, I focused on whether such differences are reflected in management selection (which is linked to adverse selection and moral hazard problems) and in compensation design (the choices of performance measurements, performance pay, and in stock option or restricted stock). The results are consistent with my expectation – the nature of ownership structure does affect senior management compensation design. Policy implications are discussed accordingly.

Description
The theme for this work is the development of fast numerical algorithms for sparse optimization as well as their applications in medical imaging and source localization using sensor array processing. Due to the recently proposed theory of Compressive Sensing (CS), the $\ell_1$ minimization problem attracts more attention for its ability to exploit sparsity. Traditional interior point methods encounter difficulties in computation for solving the CS applications. In the first part of this work, a fast algorithm based on the augmented Lagrangian method for solving the large-scale TV-$\ell_1$ regularized inverse problem is proposed. Specifically, by taking advantage of the separable structure, the original problem can be approximated via the sum of a series of simple functions with closed form solutions. A preconditioner for solving the block Toeplitz with Toeplitz block (BTTB) linear system is proposed to accelerate the computation. An in-depth discussion on the rate of convergence and the optimal parameter selection criteria is given. Numerical experiments are used to test the performance and the robustness of the proposed algorithm to a wide range of parameter values. Applications of the algorithm in magnetic resonance (MR) imaging and a comparison with other existing methods are included. The second part of this work is the application of the TV-$\ell_1$ model in source localization using sensor arrays. The array output is reformulated into a sparse waveform via an over-complete basis and study the $\ell_p$-norm properties in detecting the sparsity. An algorithm is proposed for minimizing a non-convex problem. According to the results of numerical experiments, the proposed algorithm with the aid of the $\ell_p$-norm can resolve closely distributed sources with higher accuracy than other existing methods.

Description
Geology and its tangential studies, collectively known and referred to in this thesis as geosciences, have been paramount to the transformation and advancement of society, fundamentally changing the way we view, interact and live with the surrounding natural and built environment. It is important to recognize the value and importance of this interdisciplinary scientific field while reconciling its ties to imperial and colonizing extractive systems which have led to harmful and invasive endeavors. This intersection among geosciences, (environmental) justice studies, and decolonization is intended to promote inclusive pedagogical models through just and equitable methodologies and frameworks as to prevent further injustices and promote recognition and healing of old wounds. By utilizing decolonial frameworks and highlighting the voices of peoples from colonized and exploited landscapes, this annotated syllabus tackles the issues previously described while proposing solutions involving place-based education and the recentering of land within geoscience pedagogical models.

Description
This study investigates the relation between credit supply competition among banks and their clients’ conditional accounting conservatism (i.e., asymmetric timely loss recognition). The Interstate Banking and Branching Efficiency Act (IBBEA) of 1994 permits banks and bank holding companies to expand their business across state lines, introducing a positive shock to credit supply competition in the banking industry. The increase in credit supply competition weakens banks’ bargaining power in the negotiation process, which in turn may weaken their ability to demand conservative financial reporting from borrowers. Consistent with this prediction, results show that firms report less conservatively after the IBBEA is passed in their headquartered states. The effect of the IBBEA on conditional conservatism is particularly stronger for firms in states with a greater increase in competition among banks, firms whose operations are more concentrated in their headquarter states, firms with greater financial constraints, and firms subject to less external monitoring. Robustness tests confirm that the observed decline in conditional conservatism is causally related to the passage of IBBEA. Overall, this study highlights the impact of credit supply competition on financial reporting practices.

Description财富管理是一个高度信息不对称的行业，因此投资人需要尽可能减少自身的不确定来做投资决策，通过文献整理，本文发现通过建立信任来消除不确定性是很多投资人都会选择的帮助投资决策的方法。纵观历史，美国2007-2008年的金融危机也恰恰导致金融市场投资人对于理财机构信任的严重缺失，相同的情况也可能发生在中国财富管理市场，因此本文将此选作研究重点，希望深入研究财富管理公司投资人对理财师的信任来得到一系列结论。本文最终发现就平台和理财师相比，投资人更看重平台的信誉度。 投资人大多认为平台的信誉度要高于理财师的信誉度，但是这并不意味着理财师不重要。本文进一步的分析发现，多数投资人会和理财师建立起一种私人联系，且该私人关系有助于加强客户和平台的联系。投资人认为行业经验、为人诚恳，说话可信以及责任心是加强这种私人关系的重要因素。最后，投资人对于钜派平台的信任主要由对于理财师的信任来维持，同时对于理财师的信任主要来自与情感信任。本文的发现对财富管理平台具有战略意义。

Description摘要
在复杂多变的商业环境中，企业传统的人力资源管理已经难以应对日益频发的员工职业倦怠、人际间矛盾冲突、频繁跳槽等局面与问题。企业员工工作的价值与意义早已不再是传统的雇佣模式下，通过出卖劳动力或智力从而获得工资以实现“养家糊口”的目的那么单纯与简单，员工也希望通过辛勤的工作，以获得个体的幸福感、荣誉感与认同感等。对于现代企业的管理者而言，员工追求事业的提升、个人价值的实现，不仅体现在薪酬、福利待遇的提升，更重要的是员工个人的成长以及潜能和竞争力的提升。
随着组织行为学和心理学的不断发展与演变，与员工幸福感相关的研究备受关注。对现代企业而言，管理者借助制度设计对员工幸福积极管理，可以最大限度地发挥员工的积极性、主动性与创造性，实现员工与企业之间的利益相趋同，从而更为高效地实现组织的目标。基于此，本文以民营企业员工工作幸福感作为研究的切入点，借助理论分析、问卷调查和实证分析相结合的研究方法，系统深入地研究我国民营企业员工工作幸福感的构成、可控前因和绩效后果等问题。
本文研究发现：
第一，员工薪酬的提高有助于员工工作幸福感的提升，薪资对基层员工幸福感的影响显著高于其对高层员工幸福感的影响；
第二，完善的晋升机制对于中层员工而言更能提升其幸福感，完善的晋升机制更有利于中层员工；
第三，公平性的提高有助于提高员工工作幸福感，而且这种正效应更多体现在基层员工群体之中；
第四，高层员工更注重自我价值的实现，高层员工的工作挑战性越高，其自我实现需求获得的满足感则约高，但是对于基层员工和中层员工而言，其效果则恰恰相反，基础员工和高层员工更多地将工作挑战性和压力看作是一种负面的因素；
第五，员工幸福感的确会给企业带来正向的绩效。
本文的研究框架和实证结论不仅可以丰富学术界有关员工工作幸福感的研究，而且为企业管理者进行绩效管理以及员工工作质量的提升提供理论和实证借鉴。

Description当前各个城市都在努力推动“互联网+政务”的公共服务新模式，打造政府公共服务平台，提供“一站式”的服务资源，以民众需求为中心，解决民众信息查询、政府办事预约、政策咨询等公共活动的需要。可以看出，政务平台给民众的生活带来极大的便利，是当前各地政府响应中央建立“智慧城市”“数字中国”的重要举措。
本课题发现当前的政务平台逐步引入PPP模式，借助社会资源开发政务平台。但是，PPP模式是否有利于政务平台的建设，受到哪些因素的制约，如何更好地利用PPP模式进行开发工作，这些问题在现前的研究中没有得到很好地探索。带着这些问题，本课题对PPP模式在政务平台建设中的作用进行了深入剖析。主要研究内容如下：
在第一部分中，本课题政府公共服务和政务相关理论进行了全面整理，发现政务平台要想走出一条健康发展之路，需要借助社会资源进行市场化，而PPP模式符合当前政务平台建设的需要。本文对PPP模式在国内外电子政务的应用进行了分析，提出了本文的研究主题。
在第二部分中，本文对华东地区50座城市的政务平台进行了调研，对常见问题进行了整理，发现PPP模式已经广泛应用于政务平台建设中，且主要有四种模式，本文对50座城市的政务平台建设情况进行了数据采集，并进行了深入分析。
在第三部分中，结合调研现状和文献研究成果，提出了PPP模式影响政务平台建设的相关假设，并构建了计量模型。通过短面板分析验证假设，并进行了Robust分析，证实结论的普适性。
在第四部分中，本文分析了研究结果，认为政务平台采用PPP模式能够有效促进政务平台的建设水平，提高用户满意度；并且PPP模式与合作企业的估摸、信息的透明程度和平台的交互能力存在显著的交互作用，共同影响用户对政务平台的评价。政府引入PPP模式，充分对接可利用资源，并加强盈利控制，对当前政务平台的建设是具有积极意义的。
