Published: September 2019

AbstractOBJECTIVEA fundamental goal of the auditory system is to parse the auditory environment into distinct perceptual representations. Auditory perception is mediated by the ventral auditory pathway, which includes the ventrolateral prefrontal cortex (vlPFC) late. Because large-scale recordings of auditory signals are quite rare, the spatiotemporal resolution of the neuronal code that underlies vlPFC’s contribution to auditory perception has not been fully elucidated. Therefore, we developed a modular, chronic, high-resolution, multi-electrode array system with long-term viability.APPROACHWe molded three separate μECoG arrays into one and implanted this system in a non-human primate. A custom 3D-printed titanium chamber was mounted on left hemisphere. The molded 294-contact μECoG array was implanted subdurally over vlPFC. μECoG activity was recorded while the monkey participated in a “hearing-in-noise” task in which they reported hearing a “target” vocalization from a background “chorus” of vocalizations. We titrated task difficulty by varying the sound level of the target vocalization, relative to the chorus (target-to-chorus ratio, TCr).MAIN RESULTSWe decoded the TCr and the monkey’s behavioral choices from the μECoG signal. We analyzed decoding capacity as a function of neuronal frequency band, spatial resolution, and time from implantation. Over a one-year period, we were successfully able to record μECoG signals. Although we found significant decoding with as few as two electrodes, we found near-perfect decoding with ∼16 electrodes. Decoding further improved when we included more electrodes. Finally, because the decoding capacity of individual electrodes varied on a day-by-day basis, high-density electrode arrays ensure robust decoding in the long term.SIGNIFICANCEOur results demonstrate the utility and robustness of high-resolution chronic µECoG recording. We developed a new high-resolution surface electrode array that can be scaled to cover larger cortical areas without increasing the chamber footprint.

ABSTRACTL-Tyrosine (Tyr) is an aromatic amino acid synthesizedde novoin plants and microbes downstream of the shikimate pathway. In plants, Tyr and a Tyr pathway intermediate, 4-hydroxyphenylpyruvate (HPP), are precursors to numerous specialized metabolites, which are crucial for plant and human health. Tyr is synthesized in the plastids by a TyrA family enzyme, arogenate dehydrogenase (ADH/TyrAa), which is feedback inhibited by Tyr. In addition to ADH enzymes, many legumes possess prephenate dehydrogenases (PDH/TyrAp), which are insensitive to Tyr and localized to the cytosol. Yet the role of PDH in legumes is currently unknown. This study isolated and characterizedTnt1-transposon mutants ofMtPDH1(pdh1) inMedicago truncatulato investigate PDH function. Thepdh1mutants lackedPDHtranscript, PDH activity, and displayed little aberrant morphological phenotypes under standard growth conditions providing genetic evidence thatMtPDH1is responsible for the PDH activity detected inM. truncatula. Though plant PDH enzymes and activity have been specifically found in legumes, nodule number and nitrogenase activity ofpdh1mutants were not significantly reduced compared to wild-type (Wt) during symbiosis with nitrogen-fixing bacteria. Although Tyr levels were not significantly different between Wt and mutants under standard conditions, when carbon flux was increased by shikimate precursor feeding, mutants accumulated significantly less Tyr than Wt. These data suggest that MtPDH1 is involved in Tyr biosynthesis when the shikimate pathway is stimulated, and possibly linked to unidentified legume-specific specialized metabolism.

A regression-based algorithm for frequent itemsets mining
Authors: Jia Zirui , Wang Zengli 
Published: September 2019

Purpose
Frequent itemset mining (FIM) is a basic topic in data mining. Most FIM methods build itemset database containing all possible itemsets, and use predefined thresholds to determine whether an itemset is frequent. However, the algorithm has some deficiencies. It is more fit for discrete data rather than ordinal/continuous data, which may result in computational redundancy, and some of the results are difficult to be interpreted. The purpose of this paper is to shed light on this gap by proposing a new data mining method.

Design/methodology/approach
Regression pattern (RP) model will be introduced, in which the regression model and FIM method will be combined to solve the existing problems. Using a survey data of computer technology and software professional qualification examination, the multiple linear regression model is selected to mine associations between items.

Findings
Some interesting associations mined by the proposed algorithm and the results show that the proposed method can be applied in ordinal/continuous data mining area. The experiment of RP model shows that, compared to FIM, the computational redundancy decreased and the results contain more information.

Research limitations/implications
The proposed algorithm is designed for ordinal/continuous data and is expected to provide inspiration for data stream mining and unstructured data mining.

Practical implications
Compared to FIM, which mines associations between discrete items, RP model could mine associations between ordinal/continuous data sets. Importantly, RP model performs well in saving computational resource and mining meaningful associations.

Originality/value
The proposed algorithms provide a novelty view to define and mine association.
Customer perceptions of Korean digital and traditional banks
Authors: Shin Jae Woo , Cho Ji Yeon , Lee Bong Gyou 
Published: September 2019

Purpose
The purpose of this paper is to compare customer experience (CE) between digital and traditional South Korean bank users and its relationship with customer satisfaction (CS).

Design/methodology/approach
A survey of bank customers was conducted, and an ANOVA test was performed to compare the means of CS between digital and traditional bank (TB) users as well as four dimensions of CE, such as usefulness, convenience, employee-customer engagement (ECE) and security. The ordinal regression analysis was also performed to test the moderation effect of digital bank (DB) use on the relationship between CE and satisfaction.

Findings
The means of usefulness were higher among DB users than TB users. By contrast, ECE and security means were lower for digital than TB users. The ordinal regression analysis indicated that DB use had a moderating effect on the relationship between convenience and CS and the relationship between ECE and CS. DB use encouraged increased positive relationships between convenience and CS, and moderated the relationship between ECE and CS in a negative direction.

Practical implications
ECE and security for DBs is weak. Therefore, bank executives need to improve these areas through real-time customer services and adding authentication procedures.

Originality/value
Unlike previous studies, this study proposed a model that reveals differences in CE between traditional and DB users. It explored the effects of CE on CS to contribute to the continued development of South Korean DBs.
Design of a low-cost mini quadrotor and altitude control using a micro laser sensor
Authors: Kim JeongHwan , Aurecianus Steven , Nam Seonglok , Park Jungkeun , Kang Taesam 
Published: September 2019

Purpose
The purpose of this paper is to introduce a low-cost quadrotor that can be used for educational purposes and investigate the applicability of a low-cost MEMS laser sensor for accurate altitude control.

Design/methodology/approach
A single printed circuit board is designed to form the structure of the quadrotor. A low-cost MEMS motion sensor, a microcontroller and four small motors are mounted on the board. A separate laser sensor module measures the altitude. A remote controller is designed to control the quadrotor’s motion. The remote controller communicates with the quadrotor via wireless connection. Roll and pitch attitude stabilization is achieved using the proportional and derivative control algorithm. The applicability of an MEMS laser sensor for altitude control is also studied.

Findings
The low-cost quadrotor works well even though its body structure is made using a printed circuit board. Low pass and Kalman filters work well for attitude estimation and control application. The laser sensor is very accurate and good for altitude feedback; however, it has a relatively short measurement range and its sampling rate is relatively slow, which limits its applications. The vertical velocity obtained by differentiating the laser altitude has delay and inhibits suitable damping. Using the vertical velocity obtained by integrating the vertical accelerometer’s output, the damping performance is improved.

Originality/value
Developing a low-cost quadrotor that can be used for educational purposes and successfully implementing altitude control using a laser sensor and accelerometer.
Educators’ perceptions of the value of coach mindset development for their well-being
Authors: Lowery Kendra 
Published: September 2019

Purpose
The purpose of this paper is to examine high school educators’ (three teachers, a career counselor and a social worker) perceptions of training to develop a coach mindset and the perceived impact of the training on their professional and personal well-being.

Design/methodology/approach
Individual semi-structured interviews and 16 h of observational data of professional development were collected.

Findings
Five themes emerged from the data. Participants: challenged themselves to work on coach skills; affirmed the importance of relationships; identified areas of increased skill development; envisioned coach training throughout the school; and applied a coach mindset in other domains. These themes are related to two constructs of psychological capital – efficacy and hope – which contributed to participants’ professional and personal well-being.

Research limitations/implications
The low number and selection of participants make transferability of the findings difficult.

Practical implications
Findings indicate that a coach mindset may increase educators’ well-being as they learn to build positive student, collegial and personal relationships. Recommendations for further research include exploring relationships between the development of a coach mindset, increased positive student outcomes and educator well-being.

Social implications
The development of a coach mindset may lead to increased educator well-being and positivity.

Originality/value
As few empirical studies exist regarding the effectiveness of coach training for teachers, the findings of this study fill a gap in the literature regarding these topics.
Industry 4.0 adoption as a moderator of the impact of lean production practices on operational performance improvement
Authors: Tortorella Guilherme Luz , Giglio Ricardo , van Dun Desirée H. 
Published: September 2019

Purpose
The purpose of this paper is to examine the moderating role of Industry 4.0 technologies on the relationship between lean production (LP) and operational performance improvement within Brazil, a developing economy context.

Design/methodology/approach
One representative from each of the 147 studied manufacturing companies filled in a survey on three internally related lean practice bundles and two Industry 4.0 technology bundles, with safety, delivery, quality, productivity and inventory as performance indicators. As this study was grounded on the contingency theory, multivariate data analyses were performed, controlling for four contingencies.

Findings
Industry 4.0 moderates the effect of LP practices on operational performance improvement, but in different directions. Process-related technologies negatively moderate the effect of low setup practices on performance, whereas product/service-related technologies positively moderate the effect of flow practices on performance.

Originality/value
With the advent of Industry 4.0, companies have been channelling their efforts to achieve superior performance by advancing levels of automation and interconnectivity. Eventually, widespread and proven manufacturing approaches, like LP, will integrate such technologies which may, in turn, impair or favour operational performance. Contrary to previous studies, the contingencies appeared to have a less extensive effect. The authors point to various options for further study across different socio-economic contexts. This study evidenced that purely technological adoption will not lead to distinguished results. LP practices help in the installation of organisational habits and mindsets that favour systemic process improvements, supporting the design and control of manufacturers’ operations management towards the fourth industrial revolution era.
The parameter identification model considering both geometric parameters and joint stiffness
Authors: Bai Jing , Fan Le , Zhang Shuyang , Wang Zengcui , Qin Xiansheng 
Published: September 2019

Purpose
Both geometric and non-geometric parameters have noticeable influence on the absolute positional accuracy of 6-dof articulated industrial robot. This paper aims to enhance it and improve the applicability in the field of flexible assembling processing and parts fabrication by developing a more practical parameter identification model.

Design/methodology/approach
The model is developed by considering both geometric parameters and joint stiffness; geometric parameters contain 27 parameters and the parallelism problem between axes 2 and 3 is involved by introducing a new parameter. The joint stiffness, as the non-geometric parameter considered in this paper, is considered by regarding the industrial robot as a rigid linkage and flexible joint model and adds six parameters. The model is formulated as the form of error via linearization.

Findings
The performance of the proposed model is validated by an experiment which is developed on KUKA KR500-3 robot. An experiment is implemented by measuring 20 positions in the work space of this robot, obtaining least-square solution of measured positions by the software MATLAB and comparing the result with the solution without considering joint stiffness. It illustrates that the identification model considering both joint stiffness and geometric parameters can modify the theoretical position of robots more accurately, where the error is within 0.5 mm in this case, and the volatility is also reduced.

Originality/value
A new parameter identification model is proposed and verified. According to the experimental result, the absolute positional accuracy can be remarkably enhanced and the stability of the results can be improved, which provide more accurate parameter identification for calibration and further application.
Seeking similarity or reserving differences
Authors: Wang Changzheng , Zhou Xuechun , Huang Minxue 
Published: September 2019

Purpose
Chinese face refers to reputation, others’ respect or compliance which is gained through self-representation and role-playing. The purpose of this paper is to identify and distinguish the four dimensions of face construct: personal identity-face, family identity-face, friend identity-face and occupational identity-face. Based on this, the authors discuss and investigate the influence of four different face dimensions on a consumer’s need for uniqueness (CNFU).

Design/methodology/approach
This research uses a questionnaire survey method and convenience samples. Subjects are students from a university in Wuhan operated directly under the Ministry of Education. A total of 730 questionnaires were distributed mainly in libraries and study rooms. After eliminating invalid questionnaires, 690 questionnaires were obtained. In sum, 44.1 percent research subjects are males, and 59 percent of them are undergraduate samples; 92.5 percent subjects’ monthly disposable consumption was less than 2,000 yuan.

Findings
The result shows that the influence paths and directions are different. Specifically, personal identity-face and family identity-face restrain CNFU through promoting interdependent self-construal, and friend identity-face and occupational identity-face facilitate CNFU through enhancing the consumer’s susceptibility to normative influence.

Originality/value
These findings are useful for clarify contemporary Chinese individuality-seeking consumption and conformity consumption behavior, and will shed light on form strategic practices, such as brand positioning and product communication.
Creativity in a theory of entrepreneurship
Authors: Caton James Lee 
Published: September 2019

PurposeThe purpose of this paper is to integrate a detailed theory of perception and action with a theory of entrepreneurship. It considers how new knowledge is developed by entrepreneurs and how the level of creativity is regulated by a competitive system. It also shows how new knowledge may create value for the innovator as well as for other entrepreneurs in the system.Design/methodology/approachThe theory builds on existing literature on creativity and entrepreneurship. It considers how transformation of mental technologies occurs at the individual and system levels, and how this transformation influences value creation.FindingsUnder a competitive system, the level of creativity is regulated by the need for new ways of doing things. Periods of crisis wherein old means of coordination begin to fail often precipitate an increase in creativity, whereas a lack of crisis often allows the system to settle to a stable equilibrium with lower levels of creativity.Research limitations/implicationsThe combination of methodology and methods facilitates a description of discrete building blocks that guide perception and enable creativity. This framing enables consideration of how a changing set of knowledge interacts with a system of prices.Practical implicationsPolicy makers must take care not to encumber markets with costs that unnecessarily constrain creativity, as experimentation makes the economic system robust to shocks.Social implicationsThis work provides a framing of cognition that allows for a linking of agent understanding that permits explicit description of coordination between agents. It relates perception and ends of the individual to constraints enforced by the social system.Originality/valueAs far as the author is concerned, no other work ties together a robust framing of cognition with computational simulation of market processes. This research deepens understanding in multiple fields, most prominently for agent-based modeling and entrepreneurship.

PurposeIntegrated care models have shown to deliver efficient healthcare, but implementation has proven to be difficult. The Support Consultation is an integrated care model, which enables full integration by bundled payment, insurer involvement, predefined care pathways and strengthening of primary care. The purpose of this paper is to provide an indication of the improvements in healthcare delivery after implementation of this proposed model and to create a base for extension to similar interfaces between primary and secondary care.Design/methodology/approachA retrospective study was used to compare the effect on the number of referred patients with non-acute cardiac complaints and the cost effectiveness before and after implementation of the Support Consultation. Patients who previously would have been referred to the cardiologist were now discussed between general practitioner and cardiologist in a primary care setting.FindingsThe first consecutive 100 patients (age 55±16 years, male 48 percent), discussed in the Support Consultation, were analyzed. Implementation of the Support Consultation resulted in a net costs (program costs and referral costs) reduction of 61 percent compared with usual care. All involved parties were positive about the program.Research limitations/implicationsThe Support Consultation has the ability to provide more effective healthcare delivery and to reduce net costs. The setting of the current study can be used as example for other specialties in countries with a similar healthcare system.Originality/valueThis study provides the potential cost savings after implementation of an integrated care model, based on real-life data.
