The ongoing proliferation of new services, applications, and contents is leading the Internet to an architectural crisis owing to its inability to provide efficient solutions to new requirements. Clean-slate architectures for the future Internet offer a new approach to tackle current and future challenges. This proposal introduces a novel clean-slate architecture in which the TCP/IP protocol stack is decoupled in basic functionalities, that is, atomic services (ASs). A negotiation protocol, which enables context-aware service discovery for providing adapted communications, is also specified. Then, we present how ASs can be discovered and composed according to requesters' requirements. In addition, a media service provisioning use case shows the benefits of our framework. Finally, a proof-of-concept implementation of the framework is described and analyzed. This paper describes the first clean-slate architecture aligned with the work done within the ISO/IEC Future Network working group.

IT consulting is becoming a norm rather than exception in this age of smart work and information revolution. As IT consulting is one of the knowledge intensive services requiring high credence on both sides, maintaining a good trustful relationship is critical in sustenance of strategic partnership between business firms and IT service firms. Trust is known to be one of the salient constructs in service relationships. In this study, building from the social psychology literature, trust is conceptualized as two dimensions : cognitive and affective trust. Using two dimensions of trust as mediators, a research model is constructed for IT consulting specific context : relationship continuance intention as the dependent construct while expertise, service performance, reputation, relationship satisfaction and value similarity as antecedents of cognitive and affective trust. 145 data points were collected through a survey of IT service client project managers retrospectively asking their experience with IT consultants. Findings suggest that cognitive trust is associated with perceived level of expertise and service performance while affective trust with relationship satisfaction and value similarity, respectively. Interestingly, the paths from reputation are found to be statistically insignificant towards both dimensions of trust, indicating IT service context would be more practically outcome oriented than any other professional service context. Also, cognitive trust seems to maintain stronger influence on relationship continuance intention as anticipated. Implications and limitations are discussed at the end.

The user interface (UI) is the part of the systems that users can see, hear and feel. That means, a user can interact with the systems through the user interface. Effective user interfaces create positive feelings of success and competence. In addition, they enable users to concentrate on their work, exploration, or pleasure. The German word "Gestalt" means "whole" as well as a figure or a shape. A comprehensive information systems (IS) literature review found that there has been little empirical evidence on the Gestalt principles in UIs that affect online users' perceived usability in a Web context. Therefore, the goals of this study are to 1) examine the relationships between Gestalt principles in UIs and online users' perceived usability in a Web context and 2) come up with design guidelines to enhance user success. Using a survey, this study explored the relationships between Gestalt principles used in six Web sites and 17 aspects of usability. The results showed that in terms of 16 aspects of usability, there are significant differences among the UIs that have different levels of Gestalt principles. In practice, online stores may use these findings to improve their Web pages. Specifically, the sixteen usability attributes can be used to check whether online stores' Web pages meet customers' user interface quality expectations.

Data envelopment analysis(DEA) has proved to be powerful for benchmarking and has been widely used in a variety of settings since the advent of it. DEA can be used in identifying the best performing units to be benchmarked against as well as in providing actionable measure for improvement of a organization's performance. However, the selection of performance benchmarks is a matter of both technical production possibilities and organizational policy considerations, managerial preferences and external restrictions. In that regards, DEA has a limited value in benchmarking because it focuses on only technical production Possibilities. This research proposes a new perspective in using DEA and a frame-work for benchmarking to select benchmarks that are both feasible and desirable in terms of organizational context. To do this, the concept of local and global efficiency is newly proposed. To show how useful the suggested concept and framework are, a case study is addressed.

Influenza A virus is a single-stranded RNA virus with a genome of negative polarity. Owing to the antigenic diversity and cross concrete shift, an immense number of novel strains have developed astronomically over the years. The present work deals with the codon utilization partialness among five different influenza A viruses isolated from human hosts. All the subtypes showed the homogeneous pattern of nucleotide utilization with a little variation in their utilization frequencies. A lower bias in codon utilization was observed in all the subtypes as reflected by higher magnitudes of an efficacious number of codons. Dinucleotide analysis showed very low CpG utilization and a high predilection of A/T-ending codons. The H5N1 subtype showed noticeable deviation from the rest. Codon pair context analysis showed remarkable depletion of NNC-GNN and NNT-ANN contexts. The findings alluded towards GC-compositional partialness playing a vital role, which is reflected in the consequential positive correlation between the GC contents at different codon positions. Untangling the codon utilization profile would significantly contribute to identifying novel drug targets that will pacify the search for antivirals against this virus.

This paper examines the concepts and language that practitioners actually use when talking about authenticity, which is one of the most significant concepts in archives, and explores how they in records and information management currently understand the construct of authenticity in their professional activities. This paper provides brief descriptive statistics drawn from a survey and then analysis related to providing authenticity; the difficulties of judging something authentic; and definitions of authenticity as used and understood in the context of respondents' professional activity. The analysis provides indications of how professionals actually understand and use the concept of authenticity in their professional work depending on the context; and how these professionals react differently to paper records and electronic records. The paper concludes with a discussion of how this preliminary analysis fits within the context of the outcomes of prior electronic records research.

Performing arts are composite art forms made through the collective participation of people who are responsible for a variety of roles with a multidimensional context. This study presents an analysis of the context to be expressed in the process of the arrangement and description of records of performing arts, with a focus on the relationship between performance work and performance planning, the relationship between performance planning and individual performance, the relationship between performance and people who participated in the performance, relationship between records and records, and the relationship between performance and records. With this, this study proposes a logical hierarchical structure that is required to express the context of the inner relationship of performing arts archives. It also suggests a model of sequential organization to describe the inner logic of the relationship between records and records.

This article is an exploratory study on the recent growth of short-hours part-time work in Korea. The short-hours part-time work has been rapidly growing among low-educated women over sixty, particularly among bereaved or divorced women, contrary to the expectation of the government that encouraged the part-time work by means of work-family balance for working mothers or middle-aged women who experienced career interruption. The short-hours part-time jobs are concentrated in social service industry, mostly elderly care service jobs, and their working conditions are extremely poor, mostly low-wage jobs with no social insurances except for health insurance. In this study, we discuss why the short-hours part-time work has grown so fast in Korea since the mid 2000s. Using various governmental statistics, we examine the effects of the labor demand and supply situations during the time period, the legal context that is related with the exempt clause of the labor law, and the institutional context related with the government's public job creation projects for the elderly. We suggest some public policies needed to slow down the growth of the short-hours part-time jobs and to elevate their working conditions.

In organizational behavior, the impact of leadership in organizations and employees' organizational citizenship behavior (OCB) have been two hot topics studied by scholars. However, previous studies have predominantly examined the organizational citizenship behavior of various generational groups. In the context of China's socialist market economy, it is necessary to study the OCB of state-owned enterprises (SOEs). Furthermore, employees' work-life balance in the context of SOEs' unique organizational cultures has also attracted much attention. Scholars have discovered that employees respond well to authentic leadership (AL). Although this observation has a theoretical basis, empirical research remains insufficient. Therefore, this study examined whether AL effectively promotes OCB among employees in SOEs. Additionally, we examined the mediating role of work-life balance and the moderating role of the adversity authentic and positive psychological capital. The research hypotheses were tested using 390 valid questionnaires from 60 teams using MPLUS 8.0. The results of the MPLUS study confirmed that AL promotes OCB. Work-life balance positively mediated between AL and OCB, adversity quotient positively moderated AL and work-life balance, while positive psychological capital positively mediated the impact of work-life balance on OCB. These findings provide empirical support for applying social exchange, adversity quotient, and resource conservation theories. Moreover, this study provides certain managerial insights through which managers can more effectively improve employees' professional behavior in SOEs.
