The social media industry has entered a new stage with intensifying competition and heightened uncertainty about future directions. The purpose of this paper is to provide analyses of the current challenges and to identify industry-wide trends that may offer a roadmap for the future.

Drawing on publicly available key performance metrics, company reports and press reports, this paper offers critical analyses of the challenges facing the major social media platforms and new trends in the social media industry.

This study identified five major trends in the current social media industry: 1) content is king, and that content is moving to visual; 2) artificial intelligence is key to competitive advantage; 3) network effects still matter, but business model innovation can overcome that barrier; 4) the need to broaden revenue sources; and 5) the strive for the everything app. In this changing environment, social media companies need to adapt and innovate their business models proactively to stay ahead.

This paper not only sheds light on the current challenges of individual social media platforms but also identifies industry-wide trends that may apply across all platforms. Taken together, these insights paint a comprehensive picture of the current industry landscape, as well as offer clues about its future directions.

This paper aims to compare the comprehensive rotorcraft analyses using the two different blade section property data sets for the blade natural frequencies, airloads, elastic deformations, the trimmed rotor pitch control angles and the blade structural loads of a small-scale model rotor in a blade vortex interaction (BVI) phenomenon.

The two different blade section property data sets for the first Higher-harmonic control Aeroacoustic Rotor Test (HART-I) are considered for the present rotor aeromechanics analyses. One is the blade property data set using the predicted values which is one of the estimated data sets used for the previous validation works. The other data set uses the measured values for an uninstrumented blade. A comprehensive rotorcraft analysis code, CAMRAD II (comprehensive analytical model of rotorcraft aerodynamics and dynamics II), is used to predict the rotor aeromechanics such as the blade natural frequencies, airloads, elastic deformations, the trimmed rotor pitch control angles and the blade structural loads for the three test cases with and without higher-harmonic control pitch inputs. In CAMRAD II modelling with the two different blade property data sets, the blade is represented as a geometrically nonlinear elastic beam, and the multiple-trailer wake with consolidation model is used to consider more elaborately the BVI effect in low-speed descending flight. The aeromechanics analysis result sets using the two different blade section property data sets are compared with each other as well as are correlated with the wind-tunnel test data.

The predicted blade natural frequencies using the two different blade section property data sets at non-rotating condition are quite similar to each other except for the natural frequency in the fourth flap mode. However, the natural frequencies using the predicted blade properties at nominal rotating condition are lower than those with the measured blade properties except for the second lead-lag frequency. The trimmed collective pitch control angle with the predicted blade properties is higher than both the wind-tunnel test data and the result using the measured blade properties in all the three test cases. The two different blade property data sets both give reasonable predictions on the blade section normal forces with BVI in the three test cases, and the two analysis results are reasonably similar to each other. The blade elastic deformations at the tip using the measured blade properties are correlated more closely with the wind-tunnel test data than those using the predicted blade properties in most correlation examples. In addition, the predictions of blade structural loads can be slightly or moderately improved by using the measured blade properties particularly for the oscillatory flap bending moments. Finally, the movement of the sectional centre of gravity location of the uninstrumented blade has a moderate influence on the blade elastic twist at the tip in the baseline case and the oscillatory flap bending moment in the minimum noise case.

The present comparison study on rotor aeromechanics analyses using the two different blade property data sets will show the influence of blade section properties on rotor aeromechanics analysis.

This paper is the first attempt to compare the aeromechanics analysis results using the two different blade section property data sets for all three test cases (baseline, minimum noise and minimum vibration) of HART-I in low-speed descending flight.

Organizations have always faced the possibility of disruptions. Traditional approaches, such as shifting risks through insurance or improving organizational resiliency, view disruptions as threats. This study aims to propose a new perspective where disruptions can also be opportunities. By adopting project portfolio management (PPM), organizations can develop proactive capabilities to manage uncertainty and prepare to exploit future disruptions.

Drawing on publicly available research reports, company reports, professional standards and press reports, this study describes key features of PPM and provides detailed practical guidance on how to apply PPM in daily operations, especially in preparation for the next disruption.

The key steps in applying PPM in daily operations are: align portfolios and projects with strategic goals and objectives; establish a robust governance framework; optimize resource capability and capacity; build and implement appropriate implementation methodologies; continuously monitor, review and optimize the project portfolio; and develop a culture that embraces risks, innovation and adaptability.

This research has several limitations and implications. On limitations, the study was constrained by publicly available data, an in-depth interview with a consulting firm and a survey based on convenient sampling. These limitations will impact the generalizability of the findings. On implications, this paper shows how organizations can prepare for future disruptions by applying PPM. There are other ways to prepare for the unpredictable future, and further research is needed to explore other methods.

The results of this study have important practical implications for all organizations and in all sectors. Major disruptions are matters of “when,” not “how,” and responsible organizations need to pay attention. Based on the PPM discipline, this research provides an approach for business executives and project management practitioners to tackle this challenge. Furthermore, portfolio managers should use this information to promote and advocate for more disciplined planning to confront the uncertain future.

The findings of this paper carry important social implications. As the recent events showed the vastness of disruptions, from extreme heat to fires in Maui, sitting idly and waiting passively for an unpredictable future is not an option. This paper advocates the need for more awareness and preparation for future disruption by applying PPM. Furthermore, this research provides concrete guidelines for organizations and practitioners to consider as they confront the unknown. Additional research should investigate other effective strategies to meet the challenges of an uncertain and volatile future.

This study offers practical steps on how organizations may manage not only to survive but also to thrive in an uncertain and volatile world.

Increasingly 3D printing is used for parts of garments or for making whole garments due to their flexibility and comfort and for functionalizing or enhancing the aesthetics of the final garment and hence adding value. Many of these applications rely on complex programming of the 3D printer and are usually provided by the vendor company. This paper introduces a simpler, easier platform for designing 3D-printed textiles, garments and other artifacts, by predicting the optimal orientation of the target objects to minimize the use of plastic filaments.

The main idea is based on the shadow-casting analogy, which assumes that the volume of the support structure is similar to that of the shadow from virtual sunlight. The triangular elements of the target object are converted into 3D pixels with integer-based normal vectors and real-numbered coordinates via vertically sparse voxelization. The pixels are classified into several groups and their noise is suppressed using a specially designed noise-filtering algorithm called slot pairing. The final support structure volume information was rendered as a two-dimensional (2D) figure, similar to a medical X-ray image. Thus, the authors named their method modified support structure tomography.

The study algorithm showed an error range of no more than 1.6% with exact volumes and 6.8% with slicing software. Moreover, the calculation time is only several minutes for tens of thousands of mesh triangles. The algorithm was verified for several meshes, including the cone, sphere, Stanford bunny and human manikin.

Simple hardware, such as a CPU, embedded system, Arduino or Raspberry Pi, can be used. This requires much less computational resources compared with the conventional g-code generation. Also, the global and local support structure is represented both quantitatively and graphically via tomographs.

This study examines what motivates firms to go and remain abroad despite uncertain profit potential. In a departure from probing traditional market-seeking, profit-driven motives, the authors explore how domestically driven, sociocultural motivations may shape the foreign market entry decisions of Korean commercial banks (KCBs). The authors argue that, due to the power imbalance between KCBs and their chaebol clients within the historical and cultural contexts of their relationships, KCBs' foreign market entries may depend more on their clients' presence in these markets than on their profit potential.

The authors focus on the foreign market entries of KCBs and their client firms. Using the data of 8 KCBs and their client firms belonging to the 60 business groups (chaebols) of Korea, the authors analyze 6,577 observations involving the dyadic relationship between a KCB and its client firm in 15 host countries from 2005 to 2014.

The authors find that the number of clients' subsidiaries operating in foreign markets may increase the likelihood of KCBs entering these markets. Moreover, when KCBs earn more domestic profit from client firms, the potential Korean market in the host country is greater, and the institutional distance between the host country and Korea is smaller.

In addition to the critical role of a bank-centered financing system in advancing a developing country and its firms, the authors’ findings suggest that firms should pay attention to the local diaspora and the institutional distance between the host and home countries in order to manage power-imbalanced relationships and make them sustainable.

The study contributes to the literature on foreign market entry by demonstrating how the home country's sociocultural factors may worsen the power imbalance, thereby pushing firms to make seemingly irrational decisions to go and stay abroad. That is, KCBs' foreign operations may be a way of seeking relational benefits with client firms, which would serve as a source of long-term domestic market profits. The authors’ findings thus highlight the need to consider how sociocultural factors may also shape firms' decision-making in their international business.

This study explores family firms' ex ante conflict management strategies to preserve their socioemotional wealth (SEW) under predictable conflict through the succession process. Specifically, the authors examine how family firms leverage the insurance-like benefits of corporate social responsibility (CSR) to mitigate the threat of foreseeable family feuds among the sons of firms' family heads.

The authors focus on the charitable donations pledged by Korean family business groups (chaebols). Using the data of 62 chaebols with generalized least squares (GLS) models, the authors analyze 711 observations from 2005 to 2017.

The authors find a positive relationship between the number of sons of a family firm's head and the firm's CSR activities such as spending on charitable donations. Furthermore, the number of daughters of heads in executive positions strengthens such a positive relationship, whereas the number of business and political marriage ties weakens this relationship.

Family heads of family businesses may leverage CSR activities and marriage ties to elite families interchangeably to ward off negative impacts from foreseeable family feuds and preserve their SEW. Thus, a policy-based incentive for CSR that encourages more family heads to use CSR as insurance would serve the public interest.

The authors contribute to the family business literature by suggesting that CSR activities can be used by family firms as an instrument to mitigate foreseeable damage to the SEW caused by family feuds. The authors also shed new light on CSR research by finding that marriage ties to elite families may reduce the strategic value of CSR activities.

This study aims to examine the interrelationship between the employee public service motivations (PSM), organisational corporate social responsibility (CSR) objectives and employee organisational commitment amongst accounts department staff in public service organisations.

Survey data is taken from tax accountants and accounts administration staff (n = 285) across seven South Korean state-owned enterprises involved in the provision of various public services (utilities, infrastructure, energy and housing). Structural equation modeling techniques are used to conduct mediation and moderated-mediation analysis.

Results show that both employee PSM and organisational CSR are significant in determining organisational commitment, especially where they result in value congruence. The authors also find that perceived levels of internal and external CSR are significant in moderating the impact of different dimensions of PSM.

As accounting in public service organisations faces growing professional and commercial demands to address stakeholder needs, the need for organisations to retain accounts staff with the necessary motivations is vital. The findings highlight the importance of value congruence in achieving long-term employee organisational commitment and the need for the CSR objectives of organisations to take account of both external and internal stakeholders.

Little research has examined the relationship between PSM and organisational commitment amongst accounting staff in the quasi-public/private state-owned enterprise sector. This despite the level of organisational (e.g. introduction of new public management approach) and professional change (e.g. regulatory changes) experienced over the past two decades and the importance of the sector in public service provision.

What determines the level of acquisition premium? This paper aims to investigate the effect of acquirers’ social capital as reflected through their network position (structural holes and network density) on the level of acquisition premiums.

This study predicts acquisition premiums using a panel data set of 324 mergers and acquisition (M&A) transactions including 161 unique acquirers over a 21-year timeframe. M&A and alliance information are obtained from the securities data company platinum database; firm financial data are obtained from the COMPUSTAT database.

The results show that alliance network social capital provides acquiring firms with information benefits, thus, reducing the acquisition premium. However, such information benefits are also contingent on target valuation uncertainty and acquirers’ structure exploitation tendency.

Different types of network structures provide different social capital influences: managers should be aware of their advantages and pitfalls when engaging in M&As. The findings suggest that firms should pay close attention to social capital when making decisions regarding acquisition premiums.

Past research has indicated that acquiring firms tend to overestimate the value of target firms. Still, little attention has been paid to organizational-level social capital in analyzing the determinants of acquisition premiums. This study offers insight into the effect of network structure on M&A acquisition premiums.

After the Korean War, South Korean politics was dominated by national security concerns. Reversing Carl von Clausewitz's well-known dictum, in South Korea, “politics is the continuation of war by other means.” Until the late 1980s, politics in South Korea was far from democratic. South Korea had five direct presidential elections (1987, 1992, 1997, 2002, and 2007) and six national assembly elections (1988, 1992, 1996, 2000, 2004, and 2008) after the democratic transition of 1987. In 1992, a civilian candidate, Young Sam Kim, was elected president. Young Sam Kim (1993–1998) prosecuted and punished former generals turned presidents Doo Hwan Chun (1980–1988) and Tae Woo Roh (1988–1993) for corruption, mutiny and treason in 1995. Dae Jung Kim (1998–2003) was elected president in 1997. For the first time in South Korean political history, regime change occurred between a ruling party and an opposition party.

In this chapter, the change and continuity of civil–military relations through the fluctuating dynamics of the democratic transition and consolidation in South Korea is examined. A positive consolidation of democratic reform is one that, while securing indisputable civilian supremacy, grants the military enough institutional autonomy for the efficient pursuit of its mission. Civilian supremacy should be institutionalized not only by preventing military intervention in civilian politics but also by ensuring civilian control over the formation and implementation of national defense policy.

In sum, despite three terms of civilian presidency, civilian supremacy has not yet fully institutionalized. Although significant changes in civil-military relations did occur after the democratic transition, they were not initiated by elected leaders with the intention of establishing a firm institutional footing for civilian supremacy. South Korea's political leaders have not crafted durable regulations and institutions that will sustain civilian control over the military.

More than six decades, Korea is still divided. The most highly militarized zone in the world lies along the demilitarized zone. How to draw the line prudently between seeking national security and promoting democracy shall be the most delicate task facing all the civilian regimes to come in South Korea. That mission will remain challenging not only for civilian politicians but also for military leaders.

This paper aims to understand the discrepancy between Germany’s immediate positive response to the so-called “Europe 2015's refugee crisis“ and the strict asylum legislation adopted in Germany in the following year.

The discrepancy is attributed to external and internal forces. The external force is Germany’s obligation to adhere to the Common European Asylum System. The internal force is the role of the different policy actors. The paper focuses on the role of the media as an example of a private policy actor. Through adopting the theory of the social construction of target populations, the paper studies how the media constructs “asylum seekers”, the target of the new asylum legislation. The role of the media is analyzed using the methodology of qualitative content analysis of a selected number of newspaper articles.

The majority of the studied articles problematized receiving and hosting refugees and focused on the reason behind migration differentiating between asylum seekers fleeing conflict areas and all others who might be abusing the asylum channel. The findings of the content analysis, as such, resonate with the amendments that focused on facilitating the integration of accepted “refugees” but restricted further entry. As such, it could be argued that these findings explain the influence of the media on the amendments and as such provide an explanation to the discrepancy between the initial response and the amendments.

The analysis focused on one newspaper. The findings, as such, are not representative. The aim is only to provide an example of how the German media dealt with the refugee crisis and to suggest using the theory chosen by the paper to analyze the link between asylum legislation and the construction of asylum seekers. To understand how asylum legislation is influenced by how asylum seekers are constructed, more studies are needed. Such studies could analyze the role played by other media outputs and/or the role played by other policy actors in constructing the target of the policy.

The media’s response is based on analyzing a sample of newspaper articles published by a German newspaper following the so-called 2015 refugee crisis. Accordingly, the findings represent an original endeavor to understand how the media reacted to the crisis.
