The purpose of this study is to suggest directions for enhancing competitiveness of corporate management by examining how individual creativity and organizational members' value innovation culture perception affect innovation behavior and knowledge sharing, and how innovation behavior and knowledge sharing affect organizational innovation performance and management outcomes In order to achieve these research objectives, the measurement variables of each variable were extracted through previous research and 423 valid samples were analyzed using SPSS 22.0 statistical package program and LISREL 9.1 to verify a hypothesis. As a result of this study, it was found that the creative thinking skills of the individual creativity, the meaningful tasks of the value innovation culture recognition, and the risk - taking culture have a significant influence on the innovation behavior. Only the meaningful tasks of organizational members' value innovation culture perception affect knowledge sharing. Innovation behavior has a significant effect on knowledge sharing and innovation performance, but not on business outcome. In addition, knowledge sharing has no significant effect on innovation performance but has a significant effect on business performance. Finally, we confirmed that innovation performance has a significant effect on management outcome.

This study analyzed on the effect worker's organizational citizenship behaviors of vision sharing and values congruence in social welfare organization. Analysis results are as follows: the higher the degree of a certificate of qualification of social welfare organization's worker and the position of organization have on active organizational citizenship behavior in social welfare organization. Most social welfare organization don't effort for vision sharing and values congruence in organization. Vision sharing and values congruence in social welfare organization result in actively organizational citizenship behaviors. Social welfare organization's purpose are to solve the social problem in communities. Therefore, the administrator of social welfare organization strive to share the vision of the organization with worker, and should pay more effort in the selection process for selecting the worker that matches with organization's value.

Conventional secret sharing techniques often derive shares from randomly generated polynomials or planes, resulting in lengthy and complex shares that are challenging to memorize and/or manage without the aid of a separate computer or specialized device. Modifying existing secret sharing methods to use a predetermined value, such as a memorizable password or bio-metric information, offers a solution. However, this approach raises concerns about security, especially when the predetermined value lacks randomness or has low entropy. In such cases, adversaries may deduce a secret S with just (t - 1) shares by guessing the predetermined value or employing brute force attacks. In this paper, we introduce a share hardening method designed to ensure the security of secret sharing while enabling the use of memorizable passwords or biometric information as predetermined shares.

In this paper, we study the uniqueness problems of entire or meromorphic functions concerning differential polynomials that share one value with multiplicity using weighted sharing method. We prove two main theorems which generalize and improve the results of Fang and Fang [2], Dyavanal [1] and others and also solve the open problem posed by Dyavanal. This method yields some new results.

In this paper, we give some uniqueness theorems of nonconstant meromorphic functions of hyper-order less than one sharing partially three or four small periodic functions with their shifts. As an application, some sufficient conditions for periodicity of meromorphic functions are given. Our results improve and extend previous results of W. Lin, X. Lin and A. Wu [11].

Shared value enhances the competitiveness of a company while simultaneously reducing societal burdens. By allowing companies to share their resources, collaborative logistics systems provide companies with an opportunity to create shared value, namely, not only economic value by enhancing the utilization of resources, but also social value by reducing energy consumptions and greenhouse gas emissions associated with logistics and transportation. Emerging businesses, such as ES3 and Flexe, have recently demonstrated how they created shared value through collaborative logistics services, for example, ES3's collaborative warehousing and direct-to-store (D2S) program, and Flexe's on-demand warehousing platform. However, the development of collaborative logistics systems is currently at a nascent stage. There are quite a few socio-technical barriers to overcome for sharing resources (data as well as infrastructure). Drawing on the socio-technical approach, this research examines how companies create both economic and social value from collaborative logistics systems. We highlight socio-technical barriers, particularly one set of social barriers, that is, competition-oriented conservatism prevalent among companies. Using the case study methodology and interview data, we closely investigate ES3 and Flexe, which provide collaborative logistics services, and demonstrate how technical and social barriers are addressed to create shared value from collaborative logistics systems.

The emerging of cloud data sharing can create great values, especially in multi-cloud environments. However, "data island" between different cloud service providers (CSPs) has drawn trust problem in data sharing, causing contradictions with the increasing sharing need of cloud data users. And how to ensure the data value for both data owner and data user before sharing, is another challenge limiting massive data sharing in the multi-cloud environments. To solve the problems above, we propose a Uniform Encoding and Parsing Framework (UEPF) with blockchain to support trustworthy and valuable data sharing. We design namespace-based unique identifier pair to support data description corresponding with data in multi-cloud, and build a blockchain-based data encoding protocol to manage the metadata with identifier pair in the blockchain ledger. To share data in multi-cloud, we build a data parsing protocol with smart contract to query and get the sharing cloud data efficiently. We also build identifier updating protocol to satisfy the dynamicity of data, and data check protocol to ensure the validity of data. Theoretical analysis and experiment results show that UEPF is pretty efficient.
