Purpose The purpose of this paper is to investigate the passenger comfort changes due to the wake turbulence impact from the formation flight (FF) leading aircraft, which can be a showstopper for the real application of FF to airliners. Design/methodology/approach Taking advantage of the overall aircraft design and optimization framework, as well as the module for FF assessment, the comfort level has been quantified for aircraft in solo flight and in FF according to ISO 2631–1 specifications concerning vibration total value. Findings The results showed that atmospheric turbulence intensity is the dominant factor in determining the passenger ride quality in comparison to the impact of formation wake flow. According to the preliminary results of this study, passengers seated away from the aircraft mass center encounter larger discomfort. In comparison to mass center, seats away from mass center also experience slightly stronger discomfort due to FF. The current simulation results show that FF is feasible without remarkably degrading passenger comfort level, which agrees well with the flight test results. Practical implications As passenger comfort is crucial for civil transport application of FF, the study carried out within this manuscript can give a preliminary indication to the showstopper of FF real-world application. Originality/value The proposed strategy can provide quantitative values for judging the possible drawbacks of FF, i.e. passenger comfort issues as mentioned in the literature. On the other hand, the aircraft level study based on reliable data and methods can give important insight for this interesting topic and further help the real-world application of FF for commercial aircraft. In addition, it can serve as preliminary studies for further design and operation modifications for aircraft in FF.

Practical Implications

Purpose The purpose of this study is to introduce the homophone emotional interest superiority effect in phonological, or sound-based, priming, whereby pseudohomophone brand names (i.e. non-words that are pronounced identically to English words, for example, Bie) prime brand meaning associated with the member of the homophone pair that is emotionally interesting (i.e. Bie will be prime brand avoidance (purchase) when consumers are emotionally interested in the homophone bye [buy]). Design/methodology/approach Studies 1 and 2 examine the effect of homophone emotional interest on brand judgements and behaviours. Study 3 investigates the role of boredom with the brand name in attenuating the homophone emotional interest superiority effect. Findings Findings indicate that pseudohomophone brand names prime brand judgements and behaviours associated with the word from the homophone pair that evokes emotional interest. Study 2 provides further evidence of homophone emotional interest as the process influencing brand judgements and behaviours. Study 3 establishes that the effect of pseudohomophone brand names on brand judgements weaken when boredom with the brand name is induced. Research limitations/implications This study is limited, as it focuses only on fictitious brands and methodologically creates boredom in a way in which may not be typical of what would be experienced in the real world. Practical implications This study has important implications for brand managers in the development of new brand names and in prioritising the intended homophone pair from a pseudohomophone brand name to influence consumer judgements and behaviours. Originality/value This study introduces and provides evidence of a homophone emotional interest superiority effect. This study also identifies a condition under which the homophone emotional interest superiority effect is attenuated.

Purpose The purpose of this paper is to respond to the essay by Cleveland and Bartsch in this issue. The paper also aims to counter argue the various drivers of global consumer culture (GCC). Design/methodology/approach Based on many findings from the study of consumer behavior, the assumed drivers of GCC are discussed and a suggestion for new research is made. Findings Instead of globalization processes that drive GCC, the most dominant process is a local-global-local cycle of global products and brands. Originality/value It offers a different approach to the study of global vs local products and brands. It is suggested that instead of continuing abstract discussions of GCC, scholars do more service to international marketing by researching developments in the real world.

Purpose The purpose of this paper is to obtain an optimal mobile robot path planning by the hybrid algorithm, which is developed by two nature inspired meta-heuristic algorithms, namely, cuckoo-search and bat algorithm (BA) in an unknown or partially known environment. The cuckoo-search algorithm is based on the parasitic behavior of the cuckoo, and the BA is based on the echolocation behavior of the bats. Design/methodology/approach The developed algorithm starts by sensing the obstacles in the environment using ultrasonic sensor. If there are any obstacles in the path, the authors apply the developed algorithm to find the optimal path otherwise reach the target point directly through diagonal distance. Findings The developed algorithm is implemented in MATLAB for the simulation to test the efficiency of the algorithm for different environments. The same path is considered to implement the experiment in the real-world environment. The ARDUINO microcontroller along with the ultrasonic sensor is considered to obtain the path length and time of travel of the robot to reach the goal point. Originality/value In this paper, a new hybrid algorithm has been developed to find the optimal path of the mobile robot using cuckoo search and BAs. The developed algorithm is tested with the real-world environment using the mobile robot.

Attack Models

Purpose Several attack models attempt to describe behaviours of attacks with the intent to understand and combat them better. However, all models are to some degree incomplete. They may lack insight about minor variations about attacks that are observed in the real world (but are not described in the model). This may lead to similar attacks being classified as the same type of attack, or in some cases the same instance of attack. The appropriate solution would be to modify the model or replace it entirely. However, doing so may be undesirable as the model may work well for most cases or time and resource constraints may factor in as well. This paper aims to explore the potential value of adding information about attacks and attackers to existing models. Design/methodology/approach This paper investigates used cases of minor variations in attacks and how it may and may not be appropriate to communicate subtle differences in existing attack models through the use of annotations. In particular, the authors investigate commonalities across a range of existing models and identify where and how annotations may be helpful. Findings The authors propose that nuances (of attack properties) can be appended as annotations to existing attack models. Using annotations appropriately should enable analysts and researchers to express subtle but important variations in attacks that may not fit the model currently being used. Research limitations/implications This work only demonstrated a few simple, generic examples. In the future, the authors intend to investigate how this annotation approach can be extended further. Particularly, they intend to explore how annotations can be created computationally; the authors wish to obtain feedback from security analysts through interviews, identify where potential biases may arise and identify other real-world applications. Originality/value The value of this paper is that the authors demonstrate how annotations may help analysts communicate and ask better questions during identification of unknown aspects of attacks faster,e.g. as a means of storing mental notes in a structured manner, especially while facing zero-day attacks when information is incomplete.

e24112 Background: The Serious Illness Care Program (SICP) is a system-based intervention, including a conversation guide, which facilitates improved advance care planning (ACP) conversations between clinicians and seriously ill patients. A recent randomized control trial found the program reduced symptoms of depression and anxiety amongst oncology out-patients and improved process outcomes. We implemented the SICP in our center to determine if the effects of this program could be translated into the real world. Methods: Two outpatient oncology clinics implemented the SICP, each over a 16-week period. Patients were identified based on an answer of “no” to the question “would I be surprised if this patient died within the next year?”, or any patient with a diagnosis of metastatic pancreatic cancer, or symptom scores of > 7 on more than three categories of the patient reported outcome dashboard. Physicians were trained on how to conduct the SICP conversation. One patient per week was identified and prepared to have the SICP conversation with the goal of at least 12 conversations in each 16-week period. Rates of SICP conversation documentation on our system’s “ACP and goals of care designation (GCD) Tracking Record” and GCD orders were recorded. Patient satisfaction after each conversation and physician comfort level over time were assessed. Results: 16 patients were identified (8 patients in each 16-week period). One patient was lost to follow-up. Of the remaining 15 patients who had the SICP conversation, 14 (93%) had documentation on the Tracking Record and 8 (53%) had a GCD order. This was a major improvement over baseline rates of documentation (e.g. < 1 % Tracking Record use and 16% GCD for patients with GI cancers). 14 patients completed satisfaction surveys, of which 12 (86%) felt “completely” or “quite a bit” more heard or understood. Physician comfort level increased from 3.6 to 4.8 and from 4.8 to 5 out of 5, respectively over each 16-week period. Conclusions: SICP implementation resulted in high rates of documentation of goals and preferences. Patients felt heard and understood by their healthcare team, and comfort in these conversations improved over time for physicians. The goal number of conversations was not met, but otherwise the SICP was feasible to implement in the real world. Further study is required to identify the appropriate triggers and barriers to routine SICP conversations.

Purpose Cyberspace is a virtual environment where instantaneous communications are initiated and consumed using computer networks without any natural or artificial boundaries. These communications are not only an exchange of information but also a catharsis on the socio-political environment of the real world. This explosion of electronic expression is often detrimental to the traditional secretive maneuvers of nation states and the exercise of its power. Unable to come to terms with the new reality nation states through legislative action or otherwise attempt to assert its sovereignty in the space that has no political and societal boundaries. This may lead to an encroachment on basic human rights that often have constitutional guarantees in the real world but may be violated in the online milieu. This paper aims to investigate this issue in detail and evaluate whether nation states are using cyber-security as a propaganda tool to transgress on electronic expression. Design/methodology/approach The Website of the UN Office of the High Commissioner for Human Rights states “In December 2013, the United Nations General Assembly adopted resolution 68/167, which expresses deep concern at the negative impact that surveillance and interception of communications may have on human rights”. It further says “The General Assembly called on all States to review their procedures, practices and legislation related to communications surveillance, interception and collection of personal data and emphasized the need for States to ensure the full and effective implementation of their obligations under international human rights law”. With this development, this paper seeks to unravel the role of nation states in using cybersecurity as a propaganda tool by raising the specter of threat to national security and economic wellbeing. The paper is based on exploratory research with data compilation from secondary sources. To collect data, various research papers, books and journals have been referenced and data available in public domain has been accumulated. Findings This paper has tried to unravel state action on cyberspace which often runs counter to the concept of civil liberties. It indicates that in terms of both national security and economic impact, cybercrime represent a very nominal threat vector. Also, cybercrime as compared with other forms of crime is again nominal. Finally, cyber laws and policies of different countries need to be more nuanced such as to allow space for civil liberties. Overall, the propaganda surrounding the malaise of cybercrime seems to be more hype than real. We already have examples of countries who have transgressed into electronic expression in cyber space. Therefore, UN has a valid reason to raise a red flag on this unfolding issue. Originality/value This paper was published at 21st Americas Conference of Information Systems held at Puerto Rico, USA, between August 13-15, 2015 (AMCIS, 2015).

Purpose To connect students with the real world of management practice, the purpose of this paper is to extend and operationalize the situated cultural learning approach (SiCuLA) through five learning processes occurring within communities of practice. These include integration of cultural contexts, authentic activities, reflections, facilitation, and the construction of a collaborative learning community. Design/methodology/approach To investigate the complex processes and principles of cultural learning, a multi-method approach is applied to an extensive comparative study of default and intervened cases within three management classes. Evidence is drawn from multiple sources of qualitative data including class observations, meeting minutes, focus groups, and group interviews with students and instructors. Findings Results indicated that in default cases, little explicit attention was given to a situated perspective of culture, or to the rich sources of cultural knowledge available among members of the classroom community. In contrast, following the intervention cases where SiCuLA was applied, there was strong evidence that much more attention was given to enhancing student contextual knowledge. Nonetheless, there were some challenges in applying these processes within the classroom context. Originality/value This is the first study to extend and operationalize SiCuLA in a classroom setting. More importantly, the evidence forms the empirical basis for deriving theoretical principles for cross-cultural management (CCM) education and training. It contributes to studying cultural contexts as sources of knowledge for learning through active co-participation. It also contributes to positive CCM learning with an emphasis on human agency that encourages students to take more responsibility and ownership of their cultural learning.
