Social media have increasingly gained credibility as information sources in emergencies. Retweeting or resharing nature has made Twitter a popular medium of information dissemination. The purpose of this article is to enhance our understanding of both linguistic style and content properties (i.e. both affective and informational contents) that drives resharing behavior or virality of disaster messages on Twitter. We investigate this issue in the context of natural disaster crisis.

In this study, the authors develop, drawing upon language expectancy and uncertainty reduction theories as an enabling framework, hypotheses about how the language (i.e. style and content) influence resharing behavior. They employ a natural language processing of disaster tweets to examine how the language – linguistic style (concrete and interactive language) and linguistic content (information- and affect-focused language) – affects resharing behavior on Twitter during natural disasters. To examine the effects of both linguistic style and content factors on virality, a series of negative binomial regressions were conducted, particularly owing to the highly skewed count data.

Our analysis of tweets from the 2013 Colorado floods shows that resharing disasters tweets increases with the use of concrete language style during acute emergencies. Interactive language is also positively associated with retweet frequency. In addition, neither positive nor negative emotional tweets drive down resharing during acute crises, while information-focused language content has a significantly positive effect on virality.

Agencies for public safety and disaster management or volunteer organizations involved in disseminating crisis and risk information to the public may leverage the impacts of the linguistic style and language content through the lens of our research model. The findings encourage practitioners to focus on the role of linguistic style cues during acute disasters. Specifically, from the uncertainty reduction perspective, using concrete language in the disaster tweets is the expected norm, leading to a higher likelihood of virality. Also, interactively frame disaster tweets are more likely to be diffused to a larger number of people on Twitter.

The language that people use offer important psychological cue to their intentions and motivations. However, the role of language on Twitter has largely been ignored in this crisis communication and few prior studies have examined the relationship between language and virality during acute emergencies. This article explains the complex and multifaceted nature of information resharing behavior using a multi-theoretical approach – including uncertainty reduction and language expectancy theory – to understand effects of language style and content cues on resharing behavior in the context of natural crisis events.

The purpose of this paper is to explore how linguistic style and message substance influence persuasion in civic crowdfunding marketplaces in which written narrative pitch become a vital communication to attract private contributions to public goods and services. Drawing on the elaboration likelihood model (ELM), the authors operationalize the linguistic style of the narrative pitch as language power and message substance as issue-relevant argument quality. In this paper, the authors examine how characteristics of both style and message are related to the outcome of civic crowdfunded projects.

The data on civic crowdfunding projects were retrieved from Spacehive, the platform that dedicated mainly to civic projects ranging from community programs, social-oriented enterprises, to infrastructure or facility development. Each of the narrative samples is analyzed using a computerized text analysis package called the Linguistic Inquiry and Word Count to extract the features of the linguistic style and message substance in the narratives. The logistic regression models are estimated to assess the impact of both linguistic style and message substance on crowdfunding decisions.

The results show that funding outcomes can be improved with psychological language dimensions (i.e. positive affective and perceptual language). However, extensive use of social language does not help project creators to increase their chance of funding performance; but instead, such language reduces the likelihood of project success. Additionally, message substance or issue-relevant information such as money and risk language influences funding outcome.

Very few empirical studies investigated the differential effects of language style and message substance on funding performance of crowdfunding campaigns. The authors draw upon the dual process of persuasion as a theoretical base to identify a comprehensive set of linguistic style and message substance and to examine the role of such features in an emerging civic crowdfunding market. This study advances the application of the dual process in ELM by identifying and examining distinct persuasive cues originating from linguistics styles and message contents.

Korean economy is demanding to change from an industrial society to an entrepreneurial society. It is asking for a generational change from the preexisting paradigms of such as labor consciousness, the concept of work and company management. Entrepreneurship is one of the key elements that will lead to a successful business performance under highly uncertain business conditions. The purpose of this paper is to examine the relationship between entrepreneurial orientation and business performance. Also, the authors look for the role of entrepreneurship education in the influence of entrepreneurial orientation on financial and nonfinancial business performance.

To accomplish the purpose of this study, the authors carried out a survey targeting nascent entrepreneurs and total early-stage entrepreneurs with less than seven years of experience. Based on the Miller’s (1983) definition, a group of questions for entrepreneurial orientation, similar to Covin and Slevin (1989), were developed.

First, among the subfactors of entrepreneurial orientation, it was clear that innovative progressiveness affected nonfinancial business performance. Second, risk-taking propensity did not influence both financial business performance and nonfinancial business performance. Third, entrepreneurship education had no connection with entrepreneurial orientation or business performance.

Nonfinancial business performances are related with long-term goals and growth potential. Innovative proactiveness affects nonfinancial business performance. Thus, entrepreneurs should look for ways to promote their innovative proactiveness. Entrepreneurship education for experienced entrepreneurs is not as effective as that for students.

In the authors’ study, survey questionnaires were sent to 200 nascent and total early-stage entrepreneurs searching for business angel investments or entrepreneurship consultants in Korea. A total of 180 entrepreneurs answered the survey questions online. There are not so many valid studies examining the effect of entrepreneurship education for nascent and total early-stage entrepreneurs in Korea.

Serial crowdfunding is becoming a common phenomenon as entrepreneurs repeatedly return to online crowdfunding to raise capital. In this study, the authors focus attention on serial crowdfunders, that is, entrepreneurs who experience launching more than one crowdfunding project. The purpose of this paper is to investigate the role of past experience on subsequent crowdfunding performance. This study also examines whether initial success vs initial failure leads serial crowdfunders to engage in more explorative behaviors (i.e. switching industry) and to take exploitative actions (i.e. adjusting campaign strategies in terms of goal setting and funding option).

Data on serial crowdfunding projects was retrieved from Indiegogo platform. The logistic regression models are estimated to assess the impact of past entrepreneurial experience on subsequent crowdfunding decisions, and to estimate the effects of the three strategies on subsequent funding performance.

The results show that serial creators who experienced successful initial crowdfunding are more likely to explore a new industry or product category in the crowdfunding market and to set a higher target capital for the subsequent campaign when they change a project category.

Despite the fact that there are a considerably large number of serial crowdfunders in crowdfunding market, relatively little research has been conducted to investigate the presence of learning benefits from a previous to a subsequent crowdfunding project. Two competing hypotheses, drawn from the attribution theory and hubris theory of entrepreneurship, were tested in this study to determine the impact of prior success vs failure experience on both subsequent crowdfunding decisions and funding performance.

Libraries can be seen as the collective identity of its employees engaged in providing a myriad of services to a community of patrons. Libraries can also exist in virtual settings, defined with descriptive parameters, described by a wider user group external to the library environment. The diverse nature of what constitutes libraries is illustrated by researchers, such as Marino and Lapintie (2015), who use the term “meta-meeting place” when describing its environs. Whatever model is used to describe contemporary libraries, the library environment usually has numerous needs and demands coming from a variety of stakeholders, from administrators to patrons. This chapter examines how we, as librarians, with users, co-construct library as both space and place.

We used a theoretical framework (social constructionism) to show how library identity is established by its users in the space planning process to address their needs and expectations and provided a case study of the main library at the University of South Florida.

We found that libraries are reflective of the vision and values of a diverse community and the social-political milieu in which they are housed. Librarians used a number of innovative methods and frames to create best/evidence-based practice approaches in space planning, re-envisioning library functions, and conducting outcomes/programmatic assessment. For librarians to create that sense of place and space for our users requires effective and open conversations and examination of our own inherent (and often unacknowledged) contradictions as to what libraries are or should be as enduring structures with evolving uses and changing users. For example, only a few of the studies focused on the spatial use and feel of libraries using new technologies or methodologies, such as social network analysis, discourse analysis, or GPS, to map the use of physical and virtual space.

First, new ways of working and engaging require reexamination of assessment and evaluation procedures and processes. To accomplish this, we must develop a more effective culture of assessment and to use innovative evaluation measures to determine use, user paths, and formal and informal groupings. Changes that affect patron and staff perceptions of library as place/third space may be difficult to assess using quantitative surveys, such as LibQual, that may not provide an opportunity for respondents to provide specifics of what “place” means to them. Second, it is important to have effective communication among all members of the library (patrons, library staff, and university administration) so that we design spaces/places that enhance the relationships among users, technology, pedagogy, and learning spaces, not just the latest “thing” in the literature.

This value of this review is to provide a social constructionist perspective (frame) on how we plan library space. This approach provides opportunities to truly engage our patrons and administration in the co-construction of what “our library” should be since it provides insight to group, place, and social dynamics.

The purpose of this study is to evaluate the effect of the perimeter heating load about the air diffusion performance index (ADPI) and propose a selection guide for proper line diffuser when perimeter heating load exists.

A high sidewall line diffuser was installed into a test room following the ISO standard 5219. The velocity and temperature distributions and the ADPI values are obtained numerically with 12 cases when the air flow rates are 425, 730 and 950 CMH and the heating loads are 0, 25, 50 and 75 percent of the total heating load, 2,143 W.

The ADPI decreases according to the increases of the flow rate on every heat load ratio of the present study except 0.75 with the line diffuser installed at the high sidewall. And we produced ADPI curves when the sidewall heating load exists or not in the same air flow rate and supply conditions. From that, it is possible to assume that the throw length guarantees more than 80 percent of ADPI with heating load on the wall.

Further work by the authors is focusing on making of database of various other diffusers which are generally used in the field.

This paper provides a modified selection guide for proper sidewall line diffusers to field engineers when perimeter heating load exists on the walls.

Aims to discuss iron loss analysis and experimenting with linear oscillating actuator for linear compressor.

The iron loss analysis of the linear oscillating actuator is performed by using ANSYS and iron loss curves, which is obtained by an Epstein test apparatus.

The way to calculate the iron loss of the linear oscillating actuator for the linear compressor and the method to experiment the iron loss of that can be studied.

Iron loss analysis of the linear compressor considering the motor part and the structure part is needed.

Each iron loss analysis method examined here can be used to analyze the iron loss of the linear motor.

The purpose of this paper is to examine undergraduates' perception and use of two distinct library spaces – social and communal – in an academic library in order to provide more customized services.

A survey was conducted at D.H. Hill Library at North Carolina State University, including structured questions on perceptions and use of the library, perceptions of library layout and design, and respondent demographics, as well as open questions on the advantages and disadvantages of social and communal spaces.

Undergraduates frequently use the physical library. Their usage patterns mirror common characteristics of Generation Y by going there mostly on weekday nights, with friends or in a group. Both communal and social spaces appear to be well‐used for many different activities ranging from solitary academic work to technology‐driven collaborative work and socializing. Some demographic variables, such as ethnicity and gender, are found to affect aspects of perception and use. For example, African American and Asian students tend to engage in activities that involve library technology, tools and resources, while White students simply use the spaces. Despite their excitement and appreciation of the social spaces in the library, students consider the quiet communal spaces integral to their experience of the library and stress the need of quiet space for academic work.

This is one of a few systematic empirical studies on end‐users' use of library space.

The purpose of this paper is to review a selection of articles and books that highlight aspects of spatial theory and literacy from various disciplinary perspectives, along with a review of library space studies.

This study reviews library literature that uses spatial literacy and its related tools. The authors searched in two databases: Library, Information Science & Technology Abstracts, and SCOPUS. The paper records were analyzed to find primary research studies, published between 2010 and 2017, which study patron use of library space using various single and hybrid methodologies.

The findings of the literature reveal that of the 26 studies reviewed, 23 have a descriptive research question and three have a relational research question. Based on the analysis of the research methodologies used, there is more that can be done in support of a librarian’s research efforts as well as the arenas in which research is conducted.

These findings highlight ways in which library and information science researchers and those who educate them can broaden knowledge within the profession regarding spatial theory, literacy and applicable research methodologies for studying library space.

Current and best practices for designing library space studies that use spatial literacy to collect and analyze data are identified along with a discussion of future directions for researchers to better assess space and communicate the value of physical space in libraries.

The weapon system of The Navy is the small quantity producing system on multiple kinds. It is consisted of various equipment and the subordinate parts of those which can repair the damaged part. The operating procedure concerning warship's repair parts managed under these systems is as follows. Firstly, if demand of repair parts occurs from warship which is the operating unit of weapon, then the Fleet(the repair & supply support battalion) is in charge of dealing with these requests. If certain request from warship is beyond the battalion's capability, it is delivered directly to the Logistic Command. In short, the repair and supply support system of repair parts can be described as the multi-level support system. The various theoretical researches on inventory management of Navy's repair parts and simulation study that reflects reality in detail have been carried out simultaneously. However, the majority of existing research has been conducted on aircraft and tank's repairable items, in that, the studies is woefully deficient in the area concerning Navy's inventory management. For that reason, this paper firstly constructs the model of consumable items that is frequently damaged reflecting characteristics of navy's repair parts inventory management using ARENA simulation. After that, this paper is trying to propose methodology to analyze optimal inventory level of each supply unit through OptQuest, the optimization program of ARENA simulation.
