This study tries to focus on the psychological influence by social media on user and tries to find a relationship between psychological influence and consumption patterns. Therefore, we contend that social media are platforms of interaction in that they can generate social empowerment—users feeling that they have an impact on others which gives them high self-worth (Sara Hanson, 2017) and temporarily rise self-worth can lead low self-control. Khan and Dhar (2006) find that a prior virtuous act can momentarily increase one’s self-concept, which leads to more self-indulgence in unrelated decisions. In this paper, we also investigated the two types of social media users by their presentation focus (self vs. other). In social media, there are two types of users: player & watcher. Players are users who have many followers, post lots of information about themselves and need love and attention from other users. Thus, a player which is called self-presentation focus (Wilcox, 2013) is defined as a user who focuses on information they are presenting to people in social media. In contrast, watchers are users who don’t post information on social media as actively as players but love to observe and like or dislike other users’ posts. Thus, a watcher which is called other-presentation focus (Wilcox, 2013) is defined as a user who focuses on information people present to them in social media and this is called other-presentation focus. In general, players could feel more social empowerment because posting information can be one of the activities involving interacting with other users. However, we contend that watchers will feel rather more social empowerment because having an impact, or having the feeling of social empowerment, involves the perception that one’s actions are beneficial to others, which is giving a like or comment to other user in social media (Grant and Campbell 2007). This research will have several theoretical and managerial implications. First, this study will show the influence of social media on users’ behavior and mentality, and which are related to self-control and social-empowerment. Second, this study will discover which type of social media user can be affected effectively by firms’ social media efforts.

Customers’ opinions on social network platforms are known to influence peer behaviour (Bai, 2011; Eirinaki, Pisal, & Singh, 2012). Customers are also known to be more engaged in sharing their experiences by writing online reviews and recommendations that may be useful to others (Cantallops & Salvi, 2014; Tang & Guo, 2015; Xu & Li, 2016). Actually, user-generated content (UGC) on social network platforms has emerged as an important source for understanding and managing consumers’ expectations, particularly using automated and semi-automated knowledge extraction techniques from text such as text mining and sentiment analysis (Zhang, Zeng, Li, Wang, & Zuo, 2009). This research analyses dimensions of online customer engagement and associated concepts in customers’ reviews through (i) a global sentiment analysis using positive, neutral and negative sentiments and (ii) a topic-sentiment analysis to capture latent topics in online reviews. Furthermore, it examines what influences customers to contribute their online reviews, beyond the features of each focal company or brand. The research methodology is based on a text mining approach, using the MeaningCloud tool. The study focuses on Yelp.com reviews and includes a random sample of 15,000 unique reviews of restaurants, hotels and nightlife entertainment in eleven cities in the USA. An innovative customer engagement dictionary is created, based on previously validated scales using known dimensions of engagement, experience, emotions and brand advocacy, and extended using WordNet 2.1 lexical database. The research findings reveal a high impact of the engagement cognitive processing dimension and hedonic experience on customers’ review endeavour. The study results further indicate that customers seem to be more engaged in positively advocating a company/brand than the contrary. The findings will help social network managers to reinforce their platforms.

In fashion marketing, celebrity endorsement is a widely-used strategy to gain attention and produce positive brand knowledge (Carroll, 2009). Luxury brands use their social media accounts to post pictures of celebrity endorsers using their products. This is an effective strategy because celebrity endorsement posts could encourage fans of the celebrity to repost, like or comment on this post. This is beneficial for the brand because this results in more brand exposures. The question is how luxury brands can use celebrity endorsements successfully in the digital age. For example, should luxury brands localize the celebrity endorsement in social media? The dilemma of standardization and localization becomes very significant when luxury brands are facing a culturally different market (Liu et al., 2016). This paper examines the effectiveness of localized celebrity endorsements for luxury brands in Chinese social media based on an analysis of online big data and two experiments. First, a multi-level analysis of the posts of 33 luxury brands suggests that localized (Chinese) celebrity endorsers trigger more social media interactions than standardized (Western) celebrity endorsers. Next, the following experimental studies reveal that local endorsers do not enhance perceived brand luxury and individuals’ level of patriotism moderates the effect of localized (vs. standardized) celebrity endorsements on perceived brand luxury. For people with lower level of patriotism, localized celebrity endorsements reduce the perceived brand luxury. In contrast, for people with higher level of patriotism, localized celebrity endorsements lead to higher perceived brand luxury.

Given the extreme innovativeness of this topic in marketing realm, it represents a first attempt to understanding the Agile Marketing Capability, which requires further theoretical and empirical contributions and refinements. The framework and propositions of this research may be useful for managers and decision makers to figure out the advantages of the Agile Marketing Capabilities’ employment in current marketplaces.

New media has been an important component of modern life with recent development of immersed media-rich environments (Lim & Nekmat, 2008). Jenkins and his colleagues (2006) refer such environments and their dynamics as participatory culture, in which meaning making and consumption processes are influenced by other new media users. These processes are especially attracting youth, who are open to experimentations with online identities. Such experimentation does not necessarily have to be related with entertainment. Rather it can also be related to learning and education. The primary aim of the current study is to understand the relationship between new media literacy and imaginativeness among undergraduate communication majors. The main assumption of the study is that communication undergraduates heavily use new media products and services. And such practices inevitably impact on their creative, social and practical imaginativeness. Findings aim to shed light on how interactions with the new media technologies impact on imaginative processes and practices of aspiring communication professionals.

The purpose of the study was to investigate the immediate effects of negative pressure soft tissue therapy on muscle tone, muscle stiffness and balance in patients with stroke. In total, 20 patients with stroke and assigned to the negative pressure soft tissue therapy group (NPST, n=10) or, placebo-negative pressure soft tissue therapy group(Placebo-NPST, n=10). Both groups underwent NPST or placebo-NPST once a day during the experimental period. MyotonPRO was used to assess the parameters for muscle tone and stiffness. Biorescue was used to assess the parameters for balance. Each group showed improvements in muscle tone, muscle stiffness, and balance ability (p<.05). Especially, Muscle tone, muscle stiffness, and anterior length in the limit of stability were the significant improvement on NPST group (p<.05). The results of the study suggest that the NPST is effective in improving muscle tone, muscle stiffness, and balance ability in patients with stroke.

In Korea, the daily waste production in 2015(excluding specified waste) was 404,812 tons, of which household waste accounted for 12.7%(51,247 tons/day). Total household food and vegetable waste amounted to 1,120 tons/day; of this, 70% of was ultimately used as feed or fertilizer and 30% was buried. In this study, a drying unit was developed to enable the production of solid refuse fuel using high-moisture food waste, and its performance was examined through an experiment. Thus, a laboratory pyrolysis system with a drying capacity of 500 kg/hr was manufactured. Food wastes were collected from a company cafeteria and from Changwon City and used for experiment. The drying characteristics of the food waste were examined depending on the input temperature of the drying air. The results of the food waste drying experiment showed that the total required drying time was approximately 20 hours, and the drying speed was approximately 2.90 %/hr. The drying time was five hours longer than the research target value(15 hours per batch). However, the time was approximately 16 hours when the preheating and cooling times required for the input and output were excluded, which was close to the research target value. The drying time did not show a large difference depending on the temperature of the input drying air. Drying time was 21 hours at 155℃, and thus drying operation would be possible without the use of high-temperature air(more than 200℃) when waste heat is utilized in the future. It is thought that rather than the temperature of the input air, it is the contact area between the input air and the food waste that has a significant effect on reducing the drying time.

Oral squamous cell carcinoma (OSCC) is the most common type of oral malignancy. Numerous therapies have been proposed for its cure. Research is continually being conducted to develop new forms of treatment as current therapies are associated with numerous side-effects. Luteolin, a common dietary flavonoid, has been demonstrated to possess strong anti-cancer activity against various human cancer cell lines. Nevertheless, research into luteolin-based anticancer activity against oral cancer remains scarce. Thus, the objective of this study was to assess the effect of luteolin as an anti-cancer agent. After treatment with luteolin, Ca9-22 and CAL-27 oral cancer cells showed condensed nuclei and enhanced apoptotic rate with evidence of mitochondria-mediated apoptosis. Epithelial-mesenchymal transition (EMT) is closely related to tumor migration and invasion. Luteolin suppressed cancer cell invasion and migration in the current study. Elevated expression of E-cadherin, an adherens junction protein, was evident in both cell lines after luteolin treatment. Luteolin also significantly inhibited transcription factors (i.e., N-cadherin, Slug, Snail, Twist, and ZEB-1) that regulated expression of tumor suppressors such as E-cadherin based on Western blot analysis and quantitative PCR. Thus, luteolin could induce mitochondrial apoptosis and inhibit cancer cell invasion and migration by suppressing EMT-induced transcription factors.

The purpose of this study is to analyze outsourcing ship management function at Turkish shipowning companies and Turkish shipowners’ attitudes towards third party ship management companies. A survey method was used for the study. Based on the factors collected both from literature review and interviews, a questionnaire was conducted through Turkish shipowners. The results of the study have revealed that big portion of Turkish shipowners are not willing to give the management of their vessels to third party ship management companies. This study will help researchers and ship managers to understand Turkish shipowners’ attitudes towards ship management companies and the root of shipowners’ behaviors about ship management companies. This study makes contributions to the limited literature on ship management and third party ship management by analyzing shipowners’ attitudes towards third party ship management companies in Turkey.

The proportion of collision in the total marine accidents is high. The main causes of collisions are navigation rule violation, safety speed violation, neglected watch-keeping and improper collision avoidance action. There are two main ways of avoiding collision situations during maritime navigation: the method of altering course and reducing ship’s speed. The purpose of this study is to analyze the result of the collision avoidance action of the reserve officer in case of encountering a multiple number of ships using the ship handling simulator. Full-mission ship handling simulator was used to experiment the situation scenarios that encountered multiple ships. After the experiment, the questionnaire about the experiment was investigated. A total of 50 subjects were participated in the experiment. Experimental results showed that the number of the experimenters who used the engine was 11 and the number of the experimenters who did not use the engine was 39. In the case of using the engine, there were 0 collision accident, 1 grounding accident, and 10 no accidents. However, when the engine was not used, there were 28 collision accidents, 2 grounding accidents, and 9 no accidents. The causes of these results can be found in the survey results. 74 % of the non used engine participants said they were hesitate to use the engine. As can be seen from these results, the reserve officer are hesitant to use the engine and need a way to get correct of it. Maritime course subject can emphasize the importance of using ship’s engines and case study also can be it. So, It is considered that various case study scenario will need to developed by various tools in the future.

An offshore installation is built or installed for the purposes of exploration and exploitation in any part of the sea. The offshore installations that are presently in existence reflect great scientific progress in the field of marine resources. However, they become a source of concern when they are no longer in use. Due to the potential to disrupt activities conducted around their location, they interfere with navigational safety. Therefore, it is important to remove such installations. Their removal should be based on the provisions of the IMO Guidelines and Standards. Indonesia is a coastal State and should adhere to the above mentioned guidelines and standard in designing policies and regulations.
