More than 6,000 power tiller accidents occurred in 2015, accounting for 50% of all agricultural machinery accidents. Despite this, educational institutions for farmers are only conducting theoretical education due to lack of training systems with guaranteed safety. This study developed an object motion tracking algorithm enabling trainees to control a power tiller driving simulator while wearing a HMD(head mounted display) in order to provide safe hands-on training equipment. A power tiller driving simulator was built using encoders, proximity sensors and displacement sensors to detect the locations of various operating devices such as steering clutch, and a computer model for this simulator was designed. Center coordinate synchronization of the driving simulator and the computer model was achieved with a tracker, and the motion of the power tiller driving simulator was tracked by computing position coordinates and rotation angles of the simulator. The maximum distance error was 23mm, and there was no difficulty maneuvering the driving simulator while wearing an HMD, even at maximum distance error. This motion tracking algorithm is expected to be applicable to the development of mixed reality based power tiller driving simulators for training, contributing to the reduction of power tiller accidents.

This study aligns with the recent calls in L2 Willingness to Communicate (WTC) research that mark a shift from viewing WTC as a static, trait-like variable to a construct that is dynamic, fluid, and situational. To accomplish this aim, this study collected both interactional and interview data to examine the situational changes of an ESL learner’s WTC. The data was from two courses – one ESL course, and one academic graduate seminar – collected during the participant’s first semester at an American university. The findings show that the participant’s WTC fluctuates according to the course topic, interlocutors, group size, and the anxiety level of the L2 speaker. These findings imply that teachers in L2 classrooms need to take into consideration the various situational factors that promote or inhibit WTC. Other than these pedagogical implications, the study also offers a methodological framework for documenting situational WTC by means of combining interviews with conversation analysis of interactional data.

Introduction In an age of rapid development at the information technology front, the viability of ‘smart travel destinations’ is increasingly becoming a reality (Buhalis & Amaranggana, 2014, 2015). Advances in mobile technology have allowed travel destinations to leverage the location-based wireless tracking capabilities afforded by 3/4G telecommunication networks, Bluetooth connectivity, GPS and Wi-Fi networks (Choe & Fesenmaier 2017; Eriksson, 2002). The benefits of these wireless tracking technologies include precise information on spatial behaviour (Edwards, Dickson, Griffin, & Hayllar, 2010), relevant location-based services (LBS)(Pedrana, 2014), navigational services (Eriksson, 2002), as well as recommender services (Tussyadiah & Wang, 2016). With this kind of data available to them, destination management organisations (DMOs) are able to develop more customise tourist engagement strategies which will help them communicate specifically tailored results to tourists (Edwards & Griffin, 2013). While the focus of current tourism research has been the benefits of these wireless tracking technologies (WTTs) to the destination, little research has been done to examine tourists’ perceptions of these technologies. The current exploratory study will investigate tourist perceptions of three prominent kinds of WTTs with differing levels of control at a travel destination: (1) wireless tracking only (WT only; low control); (2) Wi-Fi wireless tracking (Wi-Fi WT; moderate control); and (3) application-based tracking (App; high control). Theoretical development The current study applies the Expectancy-Value Theory in examining tourist perceptions of WTTs at a travel destination. The Expectancy-Value Theory suggests that motivation for a behaviour is determined by the desirability of the outcome i.e. benefits to the tourist (Sparks, 2007). In the context of this study, perceived personalisation and perceived innovativeness serve as benefits to tourists. Perceived personalisation is defined as the ability of a DMO to recognize and treat its tourists as individuals through personal messaging, targeted banner ads, special offers on bills, or other personal transactions” (Imhoff, Loftis, & Geiger, 2001). Perceived innovativeness reflects the degree to which a new product is seen to possess new and unique attributes and features (Fu, Jones, & Bolander, 2008). Studies have shown that perceived personalisation and perceived innovativeness positively impact on attitudes toward the product (Baek & Morimoto, 2012; Fu & Eliott, 2013), which in the context of this study relates to both the WTT itself as well as the destination. However, mere presence of WTTs can often provoke concerns about manipulative intent (Lee-Wingate & Xie, 2010) and privacy (Shilton, 2009). Inferences of manipulative intent is defined as tourist perceptions that a company is attempting to persuade via inappropriate, unfair or manipulative means (Campbell, 1995). Privacy concerns refer to the degree to which a tourist is worried about the potential invasion of the right to prevent the disclosure of personal information to others (Baek & Morimoto, 2012, p. 63). Inferences of manipulative intent and privacy concerns have been found to negatively impact on attitudes toward the product (Lee-Wingate & Xie, 2010; Shilton, 2009). Thus, the ability of a travel destination to emphasise the pros and minimise concerns for the cons of WTTs will result in more positive attitudes towards the WTT as well as the destination, which in turn, will positively impact on intention to visit the destination (based on arguments in tourism research suggesting that both attitudes toward products and the destination itself may have an impact on intention to visit e.g. Elliot, Papadopoulos & Kim 2011; Lee & Lockshin 2012). The hypothesised model for this study can be seen in Figure 1. Methodology The conceptual model was tested using data from the United States via the Amazon Mechanical Turk (MTurk) platform. A total of 750 responses were acquired but only 615 were included for analysis (responses were excluded due to incomplete data or straight-lining). A between-subjects experimental design was implemented respondents viewing a stimulus for either (1) wireless tracking only (WT only; low control); (2) Wi-Fi wireless tracking (Wi-Fi WT; moderate control); or (3) application-based tracking (App; high control). A pretest of the stimulus confirmed the levels of control proposed by the researchers. Respondents were first told to imagine their next travel destination and were then shown a stimulus. In the WT only condition, respondents were told that the destination was tracking the movement of tourists when their smartphones wireless, Bluetooth or mobile reception was turned on. In the Wi-Fi WT condition, respondents were informed that the destination would track tourists logged on to the destination’s Wi-Fi network. In the App condition, respondents were notified that the destination has an app system which allows the destination to track tourists and send them personalised push notifications. The difference between these three conditions was the level of perceived control that tourists had over the tracking of their location within the destination. Respondents then rated the WTT and destination with regards to inferences to manipulative intent, privacy concerns, perceived personalisation, perceived innovativeness, attitude toward the WTT, attitude toward the destination, and intention to visit the destination. The measures for each of these scales were chosen for their reliability and relevance to the current study. Structural equation modelling then examined the hypothesised relationships for significance. Results and discussion Exploratory and factor analysis was conducted to ensure the unidimensional of the scales. Composite reliabilities ranged from 0.70 to 0.95 and the average variance extracted scores ranged from 0.70 to 0.87, suggesting strong internal validity for all scales. All measures were also tested for convergent and discriminant validity which were both supported. Then, the hypotheses were examined using a multigroup analysis with structural equation modelling in AMOS 22. The goodness-of-fit indices for the structural model was deemed acceptable (χ²/df=1.67; RMSEA=0.03; CFI=0.97; NFI=0.94; IFI=0.90) (model comparisons revealed no significant differences at a model level suggesting that the model applied across the different groups). The results of the path analysis revealed five hypotheses which were fully supported (H1a, H2a, H3a, H3b and H6b). The remaining six hypotheses (H1b, H2b, H4a, H4b, H5 and H6a) were only partially supported with significant parameter estimates noted for either one or two of the conditions. The full result of the path analysis can be seen in Table 1. The results suggest that inferences of manipulative intent significantly decreased attitude toward the WTT, highlighting the need for destinations to be transparent about the reasons for tracking tourists. Specifically, the concealed tracking of tourists’ movements was particularly damaging to attitude toward the destination. Privacy concerns also negatively impacted on attitude toward the WTT for all conditions, but surprisingly privacy concerns appeared to significantly increase attitude toward the destination under the App condition. A potential explanation for this is the fact that despite potential for privacy infringements, tourists possess control over usage of the application, thereby moderating the ability of the destination to track them. However, this result warrants greater investigation in future studies. Perceived personalisation was noted to positively impact on attitudes toward the WTT and destination suggesting that tourists positively regarded the benefits of personalisation that the WTT afforded them. Further, perceived innovativeness appeared to positively impact on attitude towards the WTT for the App condition, but more interestingly, positively impacted on attitude toward the destination for the WT only condition. This may potentially suggest that while tourists did perceive manipulative intent in the wireless tracking of their whereabouts they also perceived this to be an innovation. Theoretically, this study extends the tourism literature with regards to the installation or application of wireless tracking technologies. It highlights the aspects that appeal to tourists as well as the concerns that they may have. From a managerial perspective, the results suggest a need for transparency as well as the empowerment of tourists to choose the degree to which their whereabouts are tracked within the destination. It offers further insights into which technologies are best suited to be leveraged in order to develop stronger tourist engagement at the destination. The implications of these results apply to destination managers, marketers as well as policy makers. A successful balance between obtaining valuable information about tourists and providing them with a choice whether or not to be tracked is crucial in ensuring favourable perception of the travel destination.

As visual marketing gains a more critical role in marketing communications, consumer eye-tracking data has been utilized to assess the effectiveness of those marketing efforts (Croll, 2016; Glazer, 2012). With eye-tracking data, researchers can capture consumers’ visual attention effectively and may predict their behavior better than with traditional memory measures (Wedel & Pieters, 2008). However, due to the complexity of data: its volume, velocity and variety, known as 3Vs of Big Data, marketing scholars have been slow in fully utilizing eye-tracking data. These data properties may pose a challenge for researchers to analyze eye-tracking data, especially gaze sequence data, with traditional statistical approaches. Commonly, researchers may analyze gaze sequences by computing average probabilities of gaze transitions from a particular area of interest to another area of interest. When the variance of gaze sequence data in the sample is small, this method would uncover a meaningful “global” trend, a trend consistent across all the individuals. However, when the variance is large, this method may not enable researchers to understand the nature of the variance, or the “messiness” of data. In this paper, first, to overcome this challenge, we propose an innovative method of analyzing gaze sequence data. Utilizing the singular value decomposition, our proposed method enables researchers to reveal a “local” trend, a trend shared by only some individuals in the sample. Second, we illustrate the benefits of our method through analyzing gaze sequence data collected in an advertising study. Finally, we discuss the implications of our proposed method, including its capability of uncovering a hidden “local” trend in “messy” gaze sequence data.

Today, customers experience a multitude of online and offline touchpoints along their shopping journeys. A customer touchpoint is defined as a direct or indirect encounter with a firm along shopping process (Baxendale et al., 2015). Touchpoints can be oneway or two-way interactions between customers and firms (Verhoef, Kannan, & Inman, 2015). Instant experiences are initiated by firms, others or by customers themselves. These experiences influence customer’s overall experience with brands, and furthermore, have impact on customers' subsequent attitude and behaviour. Another important question for managers is to decide whether to aim for creating frequent encounters: focus on volume, or creating instant experiences with stronger positive-emotional response: focus on valence. Prior research investigated different touchpoints separately and mostly focused on the effect of the volume of touchpoint encounters on attitudes and behaviour. Taking a holistic perspective, we investigate the effects of volume and valence of customers’ previous experiences of firm, others and customer initiated touchpoints on satisfaction and current purchases. We employed a real-time tracking method where respondents reported their touchpoint experiences via a mobile phones, each time they encountered the focal brand in a 4- week period in supermarket, healthcare and banking categories. We employ a twostep dynamic Heckman Probit model to investigate the impact of volume and valence of touchpoints on customer behaviour, and a multivariate regression to investigate the touchpoint effects on brand satisfaction along customer journeys. Our results reveal that brand satisfaction is mostly explained by the effect of touchpoint valence and not touchpoint volume. Our behaviour model reveals that the volume, rather than valence, of previous customer initiated purchases and transactions impacts the frequency of current purchases.

The purpose of this study was to investigate the feasibility of converting the results obtained using different rutting performance tests. The correlation between the three simulation tests was analysed to determine the conversion coefficient factor. Two parameters (temperature and speed of simulation testing) were evaluated in this study. The results of this study have shown that the values obtained in the SALS test were lower than those obtained in the HWTT and UKWTT. The conversion of the SALS test results to the HWTT results yielded a good propensity value. The temperature is important parameter for determining the conversion coefficient factor.

Block Chain is a technology that records and shares distributed ledgers without a central authority, providing a decentralized platform for transparent transactions in the business and enhancing transparency and traceability in all transactions to ensure trust in the transaction. Despite initial doubts about this technology, it is committed to adopting, adapting and improving the technology in a wide range of industries, including finance, government, security, logistics, food, medical, legal, and real estate. This study examines this technology, its applicability and potential benefits to the manufacturing supply chain. A tracking system of manufacturing supply chain to visualize transparency and traceability is implemented, and the conditions for adopting the technology in the manufacturing supply chain and the issues to be addressed are discussed.

Nueva Ecija is a landlocked province in Central Luzon region that is composed of 27 municipalities and 5 cities. It is a province that is rich with biodiversity on its north and east borders, which exhibit a shared ecosystem with the Caraballo mountain range in the north and the Sierra Madre mountain range in the east. Its main economic activity is farming where rice is the main crop. Part of the Sierra Madre mountain range traverses its towns of Bongabon, Laur, Rizal and Pantabangan where most of the locals perform agro – forestry activities as a means of generating income for their families. Due to the accumulation of farm residues as a result of intensive agro-forestry activities, mushroom pharming becomes a very viable agribusiness undertaking in the area. Our research team initiated the establishment of database by tracking the mushroom production activities in the province. Similarly, the prevailing climatic condition in the geographical area and the type of agro-forestry wastes have been tracked. Wastes as a result of intensive agro – forestry activities are being generated which the locals oftentimes burned in the field that posed hazard to the environment. In order to discourage this practice, our research team generated technologies on mushroom pharming using rice straw as the main substrate. The promotion of mushroom pharming is based on the suitability of mushroom species to grow in climatic conditions that prevail in the specific geographical area in the province. As a result of its collaborative research undertakings, the Center for Tropical Mushroom Research and Development of the Central Luzon State University in collaboration with the Laboratory of Forest Products Chemistry of Tokyo University of Agriculture and the Nikken Sohonsha Corporation encouraged the adoption of medicinal mushroom production technologies on rice straw – based formulation. With oyster mushroom (Pleurotus spp) as the most widely cultivated mushroom among the mushroom growers in the province, other ligninolytic mushrooms such as lacquered mushroom (Ganoderma) and wood ear mushroom (Auricularia spp.) are grown by the locals. Similarly, leaf – litter degrading mushrooms such as paddy straw mushroom (Volvariella volvacea) are also being cultivated in the province. However, some mushroom growers in the province adopt sawdust – based mushroom production technology which is not economically appropriate in the province due to the scarcity of its availability compared to rice straw. Majority of the mushroom growers in the province adopt the rice straw – based mushroom technology. Moreover, high value mushroom – based products other than the fresh mushrooms are already in the local market.

Collybia reinakeana (P.) Henn used to be a wild endemic edible mushroom not until it was discovered in the mountainous area of Puncan, Carranglan, Nueva Ecija, Philippines after the great earthquake that jolted Central Luzon in 1990. It is characterized to having big fruiting bodies (about 1 foot tall) that grow in cluster. Its mycelia were rescued from the wild and the first domestication studies were conducted which lead to the generation of its production technology. It is a nutraceutical mushroom that exhibits antibacterial and anti-hypertensive properties aside from its appreciable content of both standard as well as non- standard amino acids. It also exhibits mycoparasitic habit against species of Aspergillus, Cladosporium and Fusarium. Recently, emergence of this mushroom in the different areas in the Philippines have been reported which prompted our research team to conduct geo - tracking in order to rescue its secondary mycelia in our desire to conserve this endemic species of mushroom. With our conservation efforts, we have tracked the areas where it was found growing and subsequently isolated the secondary mycelia. At present, our research team were able to collect 9 different strains from the different areas namely Bataan (1), Science City of Munoz (2), Urdaneta City (1), San Manuel, Pangasinan (1), Rosales, Pangasinan (1), Bicos, Rizal, Nueva Ecija (1), Dipaculao, Aurora (1) and Bamban, Tarlac(1).
