Critical to project success is effective stakeholder management. This paper presents a challenge for the project manager who uses traditional approaches to manage mid-level stakeholders in an organization. Dual roles of a mid-level stakeholder (as a stakeholder of a project and as an agent of the corporate) may cause problems that would result in difficulties for project managers in identifying the stakeholder's attributes and overcoming hierarchical authority expectation. However, the dual roles of the stakeholder result in its weakness in the project-stakeholder relationship. Can a project leverage its strategic role for effective upward influence by linking project objectives to corporate strategic objectives? To address this research question, case study method was used to gain a deeper understanding of mid-level stakeholder's salience. This research proposes an upward influence strategy to embed a project-stakeholder relationship in a hierarchical stakeholder network.

The purpose of this study is evaluate by using ready prepared question-naires consist of items including perceived stressors. locus of control and distress to classify the different characteristics due to occupations and ages. The sampling groups ranges from 20 generations to 50 generations employed wives living with husband and children dwelling in Seoul. Finally, the sampling data used in this study are the number of 412. The major findings are as follows; (1) All employed wives feel less perceived stressors but more perceived stressors for insufficient understanding of their childrens, overload of housework, willingness of stop of employment by their parents of both families, economic expenditures, and various problems in work places. (2) There appear signigicant differences for perceived stressors and mental and physical distress due to the occupations and the ages of employed wives. Otherwise the locus of control appear clear differences due to the ages only. The more perceived stressors and mental and physical distress appear for laborious and service occupation than professional and administrative occupation. (3) The variables related to physical distress and mental distress are occupation, age, martial status and work allocation of housework, relationship childrens and relationship kinship.

As a seedbed for American Public Administration, Traditional Reform Perspective (TRP) produced Wilsonian formulation of administrative science in modern academic setting. From the beginning of the second half of the twentieth century, ideas were transported into Public Administration scholarship. New Reform Perspective (NRP) entails a belief that these reasonings are largely based on assumptions of Economics. Looking into this belief is a necessary condition, if not a sufficient one, for answering the question: Does NRP hold in the study of administration? This initial reading, though somewhat primitive, tries to set up a proposal for identifying a meaningful context for understanding the situation. As a representative version, Wilson's original perspective must be reconsidered in order to articulate the field of study within traditional reform context. According to NRP, new administrative theories are the results of the influence of economic reasoning into the field of Public Administration. Therefore, rereading of Tiebout's 'Pure Theory' and Ostrom, Tiebout and Warrens's 'Theoretical Inquiry' is a prerequisite to satisfy this particular condition.

Volatile compounds (VOCs) are not only media for communication within a species but also effective tools for sender to manipulate behavior and physiology of receiver species. Although the influence of VOCs on the interactions among organisms is evident, types of VOCs and specific mechanisms through which VOCs work during such interactions are only beginning to become clear. Here, we review the fungal volatile compounds (FVOCs) and their impacts on different recipient organisms from perspective of distinct lifestyles of the filamentous fungi. Particularly, we discuss the possibility that different lifestyles are intimately associated with an ability to produce a repertoire of FVOCs in fungi. The FVOCs discussed here have been identified and analyzed as relevant signals under a range of experimental settings. However, mechanistic insight into how specific interactions are mediated by such FVOCs at the molecular levels, amidst complex community of microbes and plants, requires further testing. Experimental designs and advanced technologies that attempt to address this question will facilitate our understanding and applications of FVOCs to agriculture and ecosystem management.

This study empirically analyzes the economic validity of rape farmers. The analysis of economic evaluation is based on the benefit-cost analysis. Previous studies have undoubtedly expanded our understanding of the importance of substitution effects on a rapeseed for bio-fuels. However, earlier studies have mostly dealt with the concept of biodiesel's economics analysis, but this paper's attentions have been paid to the economic analysis of farm. The aim of this paper is suggesting the most appropriate policy brings about why farmhouses should cultivate the rape. To answer this question, this paper adopts a scenario analysis and the B/C ratio is used.

With the availability of real-time educational data collection and analysis techniques, the education paradigm is shifting from educator-centric to data-driven lectures. However, most offline and online education frameworks collect students' feedback from question-answering data that can summarize their understanding but requires instructor's attention when students need additional help during lectures. This paper proposes a content restructure recommendation framework based on collected student feedback. We list the types of student feedback and implement a web-based framework that collects both implicit and explicit feedback for content restructuring. With a case study of four-week lectures with 50 students, we analyze the pattern of student feedback and quantitatively validate the effect of the proposed content restructuring measured by the level of student engagement.

Cell-to-cell variability in gene expression exists even in a homogeneous population of cells. Dissecting such cellular heterogeneity within a biological system is a prerequisite for understanding how a biological system is developed, homeostatically regulated, and responds to external perturbations. Single-cell RNA sequencing (scRNA-seq) allows the quantitative and unbiased characterization of cellular heterogeneity by providing genome-wide molecular profiles from tens of thousands of individual cells. A major question in analyzing scRNA-seq data is how to account for the observed cell-to-cell variability. In this review, we provide an overview of scRNA-seq protocols, computational approaches for dissecting cellular heterogeneity, and future directions of single-cell transcriptomic analysis.

The purpose of this study is to analyze the characteristics of college students majoring in the engineering on career decision difficulties and emotional and personality career difficulties. Data is consisted of 430 college students. We tested the research question by employing the PSM and the multi-regression model. The result showed that college students majoring in the engineering have difficulties in the information about self, the lack of information, and the outside control on career decision more than others. We suggested that career education and counseling of understanding themselves such as interesting, aptitude, and occupational value should be provided for students majoring in the engineering.

Star formation activity of galaxies, along with color and morphology, show significant environmental dependence in local universe, where galaxies in dense environment tend to be more quiescent and redder. However, many studies show that such environmental dependence does not continue at higher redshifts beyond z~1. The question of how the environmental dependence of galactic properties have developed over time is crucial to understanding cosmic galactic evolution. By combining data from Canada-France-Hawaii Telescope Legacy Survey(CFHTLS), Infrared Medium-Deep Survey(IMS), and other surveys, the photometric redshifts of galaxies in CFHTLS W2 field were estimated by fitting spectral energy distribution. The distribution of galaxies was mapped in redshift bins of 0.05 interval from 0.6 to 1.4. For each redshift bin, the number density was mapped. The galaxies in high density regions were grouped into clusters using friend-of-friend method. The color of galaxies were analyzed to study the correlation with redshift as well as environmental difference between field galaxies and cluster member galaxies.
