Social media management strategies for organizational impression management and their effect on public perception
Venue: J. Strateg. Inf. Syst.

Social media management strategies are modeled to influence the public perception.Distinguish a tool and a web based strategy based on company generated messages.The public perception is measured based on 15.5million user generated messages.A mixed method approach is used to qualitatively explore the quantitative results.A tool based social media management improves word of mouth and attitudinal loyalty. With the growing importance of social media, companies increasingly rely on social media management tools to analyze social media activities and to professionalize their social media engagement. In this study, we evaluate how social media management tools, as part of an overarching social media strategy, help companies to positively influence the public perception among social media users. A mixed methods approach is applied, where we quantitatively analyze 15million user generated Twitter messages containing information about 45 large global companies highly active on Twitter, as well as almost 160 thousand corresponding messages sent from these companies via their corporate Twitter accounts. Additionally, we conducted interviews with six social media experts to gain complementary insights. By these means, we are able to identify significant differences between different social media management strategies and measure the corresponding effects on the public perception.
Questioning media management scholarship: four parables about how to better develop the field

Media management scholarship has achieved increasing maturity in recent years. While acknowledging significant accomplishment, the essay provides a critical assessment to stimulate discourse in the field about what is needed to achieve next stage development in theorisation and relevance for practice. The authors present four parables to illustrate the importance of what they suggest: (1) benefitting societies as well as media industries, and thus more carefully considering our intended role as researchers and educators, (2) building theory that is multidisciplinary and of broader relevance in the social sciences, (3) broadening the methods we employ in research, and (4) challenging ourselves and our students to be more ambitious in our commitments and intentions.
Introduction: What's So Special About Media Management?

This chapter introduces the edited collection and highlights treated dimensions from the varied contributors. Taking a critical perspective on the status of this young field, the author encourages development of a broader, deeper and richer discourse that is vital for advancement in scholarly results and for practical application. Avenues for achieving that are discussed. Proposing a four part heuristic that is comprised of products, people, environment and consequences, this chapter grounds the book's thematic focus. The author addresses what is special about media management in practice and as an academic field of specialisation. Caveats are treated, as well, to clarify important limitations as a basis for future hoped for development. The chapter concludes with an overview of the editorial process.
The Development of Media Management as an Academic Field: Tracing the Contents and Impact of Its Three Leading Journals

This chapter takes stock of the development of media management as an academic field. We draw on Bird et al. (Family Business Review 15(4) 337 350, 2002) to assess how these fields measure up on three criteria that determine maturity as a discipline. While the existence of professional associations is evident in media management and career opportunities for media managers and scholars alike indicate that two prerequisites have been fulfilled, systematic theory is less evident and that is problematic. The authors reach this conclusion based on review of the most cited articles published in the three leading journals of the field (Journal of Media Economics,  Drawing on Whetten (Academy of Management Review 14(4) 490 495, 1989) the chapter observes that while considerable progress has been made in identifying the what (i.e. factors relevant to understand empirical phenomena related to media management) and quite a bit of less to how these factors are related, the why (i.e. the underlying dynamics explaining the characteristics of the field) and the who, where and when (as boundary conditions placing limitations on the theory or model) are in need of substantial work in order for a systematic body of theory about media management to develop.
Developing media management scholarship: a commentary to Picard and Lowe's essay

As eminences of the field of media management which exists as a scholarly field not least thanks to their very efforts in the essay "Questioning Media Management Research" Robert G. Picard and Gregory F. Lowe (2016) provide their thoughts about the state of the field in a fun, yet provocative way. Making use of "parables" they discuss four different, but interrelated areas for improvement of the field. All of these four areas are variations of the same theme namely, the assessment that media management scholarship should improve in quality. As much as I agree with this assessment at large, I believe that there is a need to further elaborate on how we could actually go about to further develop media management as an academic field. Therefore, the aim with this commentary to Picard and Lowe's essay is to critically discuss their analyses and provide some hands on suggestions for what we, jointly, could do to develop media management scholarship. The findings derived from Picard and Lowe's critical assessment of the media management field are not novel per se similar results have been presented for example by Achtenhagen Mierzejewska (2015) Krumsvik Ots (2016) Kung (2007) and Ots, Nyilasy, Rohn, and Wikstrom (2015) However, this is positive, as only if such assessment is shared and voiced by many scholars, change might happen and the novel approach chosen by Picard and Lowe to present their results in form of parables might certainly trigger attention and reflection. Picard and Lowe applaud that the media management field recently has seen an increase in number of different theories used, while criticising that these theories are merely applied to empirical phenomena, but neither expanded based on the empirical insights gained nor modified to fit the media management context. Interestingly, several of the theories mentioned have actually been (co )developed by general management scholars drawing on empirical examples or studies from the media industries, but being published in general management, rather than media management, journals. For example, Coser, Kadushin and Powell (1982) studied the evolution of American college textbook publishing, tracking it through a period of initial diversity to the hegemony of only two models, the large bureaucratic generalist and the small specialist. Thereby, they advanced our understanding of an important question within institutional theory, namely, why many organisations in the same industry tend to be homogeneous. Similarly, Alvarez, Mazza, Strandgaard Pedersen, and Svejenova (2005) advanced
Entrepreneurial Venturing and Media Management

Respecting the specialties of creating and managing ventures in the media sector, this chapter creates a conceptual framework for describing and explaining the creation of new media ventures in the digital era. A literature review about the interrelation between media management and entrepreneurship reveals boundaries in current research. Due to certain characteristics of digital media products, media managers have increased opportunities for the market entry of innovative media ventures. It is equally important to view this from an entrepreneurial perspective because the entrepreneur composes his business ideas as a recombination of self created opportunities. Thus, the chapter addresses venture creation as the interdependence of opportunities presented in the environment and realised by entrepreneurs. The chapter concludes with recommendations for media management practice and further research.
Social Media Management Exploring Facebook Engagement among High Asset Foundations.

Do foundations effectively use social media to engage stakeholders? Do usage and engagement vary by foundation type? This article has been written to stimulate discussion and research about social media use and user engagement by foundations beyond measuring social media presence. We analyzed Facebook usage and stakeholder engagement for three types of foundations: community, corporate, and independent grant making foundations. We found that although community foundations are more likely to have a social media presence, corporate and independent foundations are more likely to use Facebook and to effectively engage stakeholders. Findings illuminate the need to understand social media usage and engagement in addition to presence. We discuss potential benefits of social media use and provide practical communication management recommendations for nonprofit practitioners.
Special Issue Introduction: Big Data and Media Management

Like many other sectors of economic, political, and cultural life, the media industries are infatuated with the possibilities afforded by big data (see, e.g. Stone, 2014) Perhaps more so than many other industry sectors, the media industries are particularly well positioned to capture and harness the potential of big data. As a recent Forbes article noted, "media companies may have better opportunities than most.  every song listened to, every minute of video viewed, every online page that is clicked contributes to the mountains of data that tell them what audiences want" (Kim Wegener, 2014, p. 1) Media sectors in economic distress (e.g. journalism) are increasingly looking to big data in hopes that they may illuminate a path back to profitability (see, e.g. Bell, 2012) Within the media industry, specific developments, such as the emergence of Netflix as a powerhouse content distributor and, subsequently, successful producer of original content, have been attributed to the effective use of big data (see, e.g. Carr, 2013) It is worth emphasizing in the case of Netflix that its gathering and use of large data sets has extended beyond the audience data that accumulates each time a viewer watches and rates content. Indeed, one of the less discussed aspects of Netflix's evolution is that the company's analytics and decision making now also rely upon granular content analysis of all video content in the Netflix library (Madrigal, 2014) Each piece of content is coded across dozens of variables, allowing the company to segment its content offerings into over 75,000 "microgenres" on the basis of content characteristics alone. It is this additional layer of big data gathering and analytics that brought a level of analytical and predictive precision that could not be achieved by analyzing only audience consumption and rating data (Madrigal, 2014) The key point here is that big data in the media sector is not just an audience centric phenomenon; it can be content centric as well. Given this range of developments, a special issue of the International Journal on Media Management exploring the intersection of big data and media management seemed due (if not overdue) The goals for this special
On reverse Stackelberg game and optimal mean field control for a large population of thermostatically controlled loads
Venue: 2016 American Control Conference (ACC)

This paper studies a multi stage pricing problem for a large population of thermostatically controlled loads. The problem is formulated as a reverse Stackelberg game that involves a mean field game in the hierarchy of decision making. In particular, in the higher level, a coordinator needs to design a pricing function to motivate individual agents to maximize the social welfare. In the lower level, the individual utility maximization problem of each agent forms a mean field game coupled through the pricing function that depends on the average of the population control/state. We derive the solution to the reverse Stackelberg game by connecting it to a team problem and the competitive equilibrium, and we show that this solution corresponds to the optimal mean field control that maximizes the social welfare. Realistic simulations are presented to validate the proposed methods.
Where Is Current Research on Blockchain Technology? A Systematic Review
Venue: PloS one

Blockchain is a decentralized transaction and data management technology developed first for Bitcoin cryptocurrency. The interest in Blockchain technology has been increasing since the idea was coined in 2008. The reason for the interest in Blockchain is its central attributes that provide security, anonymity and data integrity without any third party organization in control of the transactions, and therefore it creates interesting research areas, especially from the perspective of technical challenges and limitations. In this research, we have conducted a systematic mapping study with the goal of collecting all relevant research on Blockchain technology. Our objective is to understand the current research topics, challenges and future directions regarding Blockchain technology from the technical perspective. We have extracted 41 primary papers from scientific databases. The results show that focus in over 80% of the papers is on Bitcoin system and less than 20% deals with other Blockchain applications including e.g. smart contracts and licensing. The majority of research is focusing on revealing and improving limitations of Blockchain from privacy and security perspectives, but many of the proposed solutions lack concrete evaluation on their effectiveness. Many other Blockchain scalability related challenges including throughput and latency have been left unstudied. On the basis of this study, recommendations on future research directions are provided for researchers.

Perception and risk factors for cervical cancer among women in northern Ghana.
Venue: Ghana medical journal

This study assessed the perception of risk of cervical cancer and existence of risk factors for cervical cancer based on five known risk factors among women attending the Tamale Teaching Hospital in Tamale, Ghana.  A consecutive sample of 300 women was interviewed using a semi structured questionnaire to inquire about risk factors and perception of risk of cervical cancer. Specific risk factors that were explored included early coitarche, multiple sexual partners, polygamous relationships, history of smoking, and having a current partner who had multiple sexual partners.  Sixty one per cent of women reported that they had no personal risk for cervical cancer. 27% of respondents were in polygamous relationships, and of those, more than half didn't think they were at an increased risk of cervical cancer. 2 women had a total of 5 sexual partners in their lifetime and neither believed they were at any risk for cervical cancer. 23% said their current partner had had at least 2 sexual partners in his lifetime, and of those, (61% thought they were at no risk for cervical cancer. 46% of respondents reported not having any of the risk factors listed in the study. 23% of respondents reported having one risk factor while 21% had two risk factors and 11% had three or more risk factors.  Women's perception of personal risk for cervical cancer is lower than their actual risk based on the five behavioural risk factors assessed and a lack of knowledge of the personal factors for the disease.  This project was supported by NIH Research Training Grant #R25 TW009345 funded by the Fogarty International Centre, in partnership with several NIH Institutes (NIMH, NIGMS, NHLBI, OAR and OWH)
Validity and reliability of three methods of stiffness assessment
Venue: Journal of sport and health science

Stiffness is commonly assessed in relation to injury and athletic performance. The purpose of this research was to compare the validity and reliability of 3 in vivo methods of stiffness assessment using 1 cohort of participants.  To determine inter day reliability, 15 female netballers were assessed for stiffness twice within 1 week using unilateral hopping (vertical stiffness) free oscillations of the calf, and myometry of various muscles of the triceps surae. To establish convergent construct validity, stiffness was compared to static and dynamic strength measurements.  Test retest stiffness results revealed that vertical stiffness produced moderate to high reliability results and myometry presented moderate to very high reliability. In contrast, the free oscillation technique displayed low to moderate reliability. Vertical stiffness demonstrated a significant correlation with rate of force development during a squat jump, whilst myometer stiffness measurements from 3 sites in the lower limb revealed significant correlations with isometric rate of force development. Further, significant negative correlations were evident between the eccentric utilisation ratio and various myometer stiffness results. No relationships were established between the free oscillation technique and any of the performance measurements.  These results suggest that vertical stiffness and myometry are valid and reliable methods for assessing stiffness.
Reliability, Validity, and Usability of Data Extraction Programs for Single Case Research Designs
Venue: Behavior modification

Single case experimental designs (SCEDs) have been increasingly used in recent years to inform the development and validation of effective interventions in the behavioral sciences. An important aspect of this work has been the extension of meta analytic and other statistical innovations to SCED data. Standard practice within SCED methods is to display data graphically, which requires subsequent users to extract the data, either manually or using data extraction programs. Previous research has examined issues of reliability and validity of data extraction programs in the past, but typically at an aggregate level. Little is known, however, about the coding of individual data points. We focused on four different software programs that can be used for this purpose (i.e. Ungraph, DataThief, WebPlotDigitizer, and XYit) and examined the reliability of numeric coding, the validity compared with real data, and overall program usability. This study indicates that the reliability and validity of the retrieved data are independent of the specific software program, but are dependent on the individual single case study graphs. Differences were found in program usability in terms of user friendliness, data retrieval time, and license costs. Ungraph and WebPlotDigitizer received the highest usability scores. DataThief was perceived as unacceptable and the time needed to retrieve the data was double that of the other three programs. WebPlotDigitizer was the only program free to use. As a consequence, WebPlotDigitizer turned out to be the best option in terms of usability, time to retrieve the data, and costs, although the usability scores of Ungraph were also strong.
Networked Traffic State Estimation Involving Mixed Fixed mobile Sensor Data Using Hamilton Jacobi equations

Nowadays, traffic management has become a challenge for urban areas, which are covering larger geographic spaces and facing the generation of different kinds of traffic data. This article presents a robust traffic estimation framework for highways modeled by a system of Lighthill Whitham Richards equations that is able to assimilate different sensor data available. We first present an equivalent formulation of the problem using a Hamilton Jacobi equation. Then, using a semi analytic formula, we show that the model constraints resulting from the Hamilton Jacobi equation are linear ones. We then pose the problem of estimating the traffic density given incomplete and inaccurate traffic data as a Mixed Integer Program. We then extend the density estimation framework to highway networks with any available data constraint and modeling junctions. Finally, we present a travel estimation application for a small network using real traffic measurements obtained obtained during Mobile Century traffic experiment, and comparing the results with ground truth data.
