Recallable but not Recognizable: The Influence of Semantic Priming in Recall Paradigms
Authors: Ozubko Jason D. , Sirianni Lindsey Ann , Ahmad Fahad N. , MacLeod Colin M. , Addante Richard James 
Published: January 2020

AbstractWhen people can successfully recall a studied word, they should be able to recognize it as having been studied. In cued recall paradigms, however, participants sometimes correctly recall words in the presence of strong semantic cues but then fail to recognize those words as actually having been studied. Although the conditions necessary to produce this unusual effect are known, the underlying neural correlates have not been investigated. Across two experiments, involving both behavioral and electrophysiological methods (EEG), we investigated the cognitive and neural processes that underlie recognition failures. Experiments 1A and 1B showed that, in cued recall paradigms, presuming that recalled items can be recognized is a flawed assumption: Recognition failures occur in the presence of cues, regardless of whether those failures are measured. Experiment 2 showed that successfully recalled words that are recognized are driven by recollection at recall and by a combination of recollection and familiarity at recognition; in contrast, recognition failures are driven by semantic priming at recall and followed by negative-going ERP effects consistent with implicit processes such as repetition fluency and context familiarity at recognition. These results demonstrate that recall—long-characterized as predominantly reflecting recollection-based processing in episodic memory—can at times also be served by a confluence of implicit cognitive processes.
Cold crucible melting with bottom pouring nozzle
Authors: Bojarevics Valdis , Pericleous Koulis 
Published: January 2020

Purpose
The purpose of this paper is to investigate a new type of nozzle which is free from erosion and non-contaminating the outflow metal. Cold crucible melting technique with electromagnetic induction is used to obtain reactive metal castings and produce high-quality metal powders for aerospace, automotive and medical applications. An important part of this technology is the nozzle used to pour the molten alloy through the bottom opening.

Design/methodology/approach
The paper uses mathematical modeling technique, previously validated on multiple similar cases, to investigate a new type of nonconsumable nozzle made of copper segments.

Findings
The design of the nozzle requires to satisfy the narrow balance between the thin solidified protective layer on the wall while avoiding the blockage of the outflow if the nozzle is frozen completely. The sensitivity of the outflow to the nozzle diameter is investigated. The AC electromagnetic force leads to high mixing rates, transitional flow structures and turbulence of the melt, contributing to the melt shape dynamics and the heat loss to walls.

Originality/value
The beneficial features of the cold crucible melting to purify the melt from particulate contamination are explained using the full melting and pouring cycle.
Tailored heating of forging billets using induction and conduction heating approaches
Authors: Schulze Martin , Baake Egbert 
Published: January 2020

Purpose
This paper aims to deal with different induction and conduction heating approaches to realize a tailored heating of round billets for hot forming processes. In particular, this work examines the limits in which tailor-made temperature profiles can be achieved in the billet. In this way, a flow stress distribution based on the temperature field in the material can be set in a targeted manner, which is decisive for forming processes.

Design/methodology/approach
For the heating of round billets by induction, the rotationally symmetric arrangement is used and a parameterized 2D finite element method model is created. The harmonic electromagnetic solution is coupled with the transient thermal solution. For heating by means of conduction, the same procedure is used only with the use of a 3D model.

Findings
First results have shown that both methods can achieve very good results for billets with small diameters (d < 30 mm). For larger diameters, an adapted control of the heating process is necessary to ensure through heating of the material. Further investigations are carried out.

Practical implications
Using tailored heating for forging billets, several forming steps can be achieved in one step. Among other things, higher energy efficiency and throughput rates can be achieved.

Originality/value
The peculiarity of the tailored heating approach is that, in contrast to inhomogeneous heating, where only partial areas are heated, the entire component is heated to the target.

The impact of lead users on innovation success
Authors: Marzouki Reem , Belkahla Wafa 
Published: January 2020

Purpose
The purpose of this paper is to study the impact of lead users (LUs) on innovation success by proposing and validating an integrative model that links LUs, innovation success and knowledge sharing (KS) variables.

Design/methodology/approach
The authors research is quantitative in nature and data were collected through a survey conducted among 30 information technology Tunisian companies. The authors preliminary analysis was explored using the “SPSS” software and processed through exploratory factor analysis and regression analysis methods.

Findings
Results showed that LUs who possess advanced skills and valuable knowledge can contribute to enhance new successful innovations, and hence, enable companies to gain short and long-term profits. Besides, the authors confirmed that the impact of LUs on innovation success is mediated by the “KS” behavior.

Practical implications
An integrative framework that links LUs, innovation success and a third variable called KS is presented to see beyond the intended importance of this type of user regarding the development of new innovations.

Originality/value
The paper offers new insights to the topic of LUs by emphasizing the role of “KS” variable in strengthening the LUs – innovation success relationship.
Development and validation of a parental social media mediation scale across child and parent samples
Authors: Ho Shirley , Lwin May O. , Chen Liang , Chen Minyi 
Published: January 2020

Purpose
Social media use carries both opportunities and risks for children and adolescents. In order to reduce the negative impacts of social media on youth, the authors focus our efforts on parental mediation of social media. Specifically, the purpose of this paper is to enhance the conceptualization and operationalization of parental mediation of social media.

Design/methodology/approach
First, the authors conducted focus groups with both children and parents in Singapore to categorize parental mediation strategies for social media and develop an initial scale of these strategies. Then, a survey was conducted with a nationally representative sample of 1,424 child participants and 1,206 parent participants in Singapore to develop and test the scale.

Findings
The focus group results identified four conceptually distinct parental mediation strategies for social media, labeled as active mediation, restrictive mediation, authoritarian surveillance, and non-intrusive inspection, and were used to develop an initial scale of these strategies. Based on the data from survey questionnaires, the authors investigated both inter-item and item-total correlations and performed confirmatory factor analysis (CFA), which developed and validated the scale of parental mediation of social media.

Originality/value
First, this research explained what parents do to manage children’s social media use and identified four conceptually distinct parental mediation strategies of social media, making a significant contribution to the parental mediation theory. Additionally, the research developed the first theory-derived, successively validated and reliable scale in parental mediation of social media.
Enhanced D-H: an improved convention for establishing a robot link coordinate system fixed on the joint
Authors: Guo Fayong , Cai Hao , Ceccarelli Marco , Li Tao , Yao Butang 
Published: January 2020

Purpose
Robot kinematic modeling needs to be based on clear physical concepts. The widely used Denavit–Hartenberg (D–H) convention requires the coordinate system to be established on an extension of the axis. This leads to non-trivial problems which this study seeks to address by developing an improved convention.

Design/methodology/approach
First, the problems associated with the traditional D–H convention are systematically analyzed. Then, pursuant of solving these problems, an enhanced Denavit–Hartenberg (ED–H) convention is proposed, and a procedure is delineated for establishing the coordinate frame and obtaining the associated parameters. The transformation equations are derived based on a homogeneous matrix. The characteristics of traditional D–H and ED–H with regard to kinematics and dynamics are comprehensively compared. Finally, an application of dynamics for lead-through programming and collision protection is undertaken to validate the proposed ED–H method. Simulations and experiments are carried out using the Tiansui-One cooperative robot platform with the aim of exploring the merits of the proposed convention.

Findings
The proposed convention is compatible with traditional methods and can solve the problems inherent in these methods. The main characteristic of ED–H is that the coordinate system is fixed on the joint, which is a general modeling method.

Originality/value
An enhanced D–H convention is proposed to establish a unified, intuitive and accurate link model that exhibits stronger adaptability than traditional D–H and can be used effectively in kinematic and dynamic modeling of mechanical arms.

Mentoring beyond the politics of fear
Authors: Russel Magill Kevin , Harper Tracy D. , Smith Jess , Huang Aaron 
Published: January 2020

Purpose
The purpose of this paper is to examine multiple dimensions of reflexive and reciprocal mentorship as they work through the fear of teaching challenging and politically charged ideas.

Design/methodology/approach
This piece is a case study of the complex instances of reciprocal mentorship within a teacher education program. Objects of analysis included the informal educational experiences from the bi-monthly meetings and student-teaching experiences. Semi-structured interviews, field notes, interpersonal discussion and the authors’ own reflections were used as data sources.

Findings
The authors found that having difficult conversations in informal spaces provided social studies teacher candidates with the opportunity to get more comfortable with challenging conversations; that mentorship is helpful when shifting context between formal and informal spaces; and that once these teachers grew more comfortable, they moved from mentee to mentor with support and guidance from their own mentors. The authors conclude by providing several implications for pre-service teachers, teacher and teacher educators, as they help social studies practitioners work with and beyond the politics of fear.

Research limitations/implications
Limitations such as subjectivity, generalizability and implementation exist. Factors such as personality, program, cultural background, lived experience and other elements played a role in the findings. Therefore, the authors do not suggest these are monolithic claims about the nature of mentorship, teacher education or teaching, but rather the authors wish to share these findings and recommendations.

Practical implications
The authors argue that three major findings emerged from the data. First, informal spaces are valuable for initiating difficult conversations among mentors and mentees. Second, shifting between formal and informal spaces can be uncomfortable, but allow for mentoring opportunities during these challenging instances of becoming. Third, moving from mentee to mentor includes valuable reciprocal mentorship within a learning community.

Originality/value
This research project is grounded in the needs of the participants and researchers. To the authors’ knowledge, a project of this type with similar participants has not been done.
The usability of visitor attractions: state-of-the-art
Authors: Navarro-Ruiz Sandra , McKercher Bob 
Published: January 2020

Purpose
Visitor attractions constitute the essence of the tourism phenomenon. However, management techniques that are expressly designed for tourism and develop different uses/activities and subsequently influence visitor experiences are under-researched. Hence, the purpose of this study is to develop a conceptual framework that provides a bridge between on-site management, visitor attraction development and visitor experience by introducing a novel concept: “usability of visitor attractions.” This new concept captures how managers can develop uses for visitors to experience the attraction. Thus, this study explores this concept and serves as the foundation for further research on this topic.

Design/methodology/approach
The systematization of the state of the art is based on an exhaustive desk research review of both academic and grey literature to endorse the “usability of visitor attractions” concept.

Findings
The literature review reveals that visitor attraction management affects visitor experience. To succeed, managers should consider the ease of use and the design of activities. Therefore, an innovative conceptual model is built to explore how on-site management techniques based on this new concept impact on visitor’s experience.

Originality/value
Research on visitor experience in attractions has neglected the impact of on-site management tools hitherto. Therefore, the originality of the study lies on providing a robust framework that enlightens how visitor attraction management affects visitor experience by developing the usability. The study proposes a novel concept and an original model that will be of a critical interest to tourism academia and will serve as practical guidance for attraction managers.

Authors: Abdulkareem Mohanad , Kenawy Inji , ElKadi Hisham 
Published: January 2020

Purpose
The purpose of this paper is to shed light on the potential of ecologically driven urban design interventions to substantiate urban form performance in coping with the increasing flood threats particularly in the Middle East region. The paper applies ecological principles to new urban interventions for pluvial flood adaptation in Muscat city, Oman. The interventions incorporate the physical dimensions of both the natural (topography) and the built environment (urban morphology). The study demonstrates different scenarios in Muscat city in Oman and discusses the different challenges faced at different socio-economic and ecological levels.

Design/methodology/approach
The paper adopts a case study approach. The methods include semi-structured interviews aiming to gain insight from experts in the field of study about salient physical interventions in the urban context that is potentially going to help mitigating flood consequences. Mitigation scenarios were guided by the participants’ recommendations in the area. Scenarios were tested across two complementary phases using two software packages, the first of which is the pre-processing phase accomplished by using the Aeronautical Reconnaissance Coverage Geographic Information System and the second is the flood analysis phase done by the Hydrological Environmental Center for River Analysis System (HECRAS) platform. The scenarios were evaluated in relation to the successfulness and reliability of physical solutions based on to which extent the flood wave depth and coverage was reduced.

Findings
The paper provides an alternative resilient holistic approach to achieve socially and ecologically sensitive and less expensive flood mitigation solutions in the Middle East.

Originality/value
The paper provides a new approach to flood mitigation linking ecological principles to the social dimension of human activities and experience in closely knitted communities.
Indeterminacy, Disagreement and the Human Rights Act: An Empirical Study of Litigation in the UK House of Lords and Supreme Court 1997–2017
Authors: Blackwell Michael 
Published: January 2020

AbstractThis article explores the impact of the Human Rights Act 1998 on the decision making of the House of Lords (UKHL) and the UK Supreme Court (UKSC). How does Convention rights content vary across areas of law in the UKHL/UKSC? Are some judges more likely than others to engage in Convention rights discourse? Is judicial disagreement more common in cases with higher levels of Convention rights discourse? A robust method of answering questions of this nature is developed and applied to decisions of the UKHL/UKSC, showing that the Convention rights content of decisions has varied over time and over substantive areas of law. Higher levels of human rights discourse are associated with greater levels of disagreement. A benchmarked measure of human rights content is developed to show the effect of the particular judge on the human rights content, illustrating the indeterminacy in human rights discourse and how its deployment can be contingent on judicial attitudes.
Dutertenomics: Populism, Progress, and Prospects
Authors: Capuno Joseph J. 
Published: January 2020

AbstractIn 2016, when Rodrigo Duterte was elected Philippine President the economy was growing robustly. Despite the record growth, his election is considered a populist revolt of the middle‐ and upper‐class Filipinos. Yet, his economic policies – from his initial 10‐point agenda to the laws he approved – are liberal. This paper distinguishes and relates Duterte's authoritarian‐populist political style (“Dutertismo”) and his economic agenda (“Dutertenomics”). The distinction follows from his lack of interest in economic affairs, which he delegated to his team of economic managers. This team ably pushes important economic reforms because of the president's style, which so far has earned him wide public approval. After slowing down during the first half of Duterte's term, growth has recently picked up. To keep the momentum and public attention off human rights violations, Duterte needs to accomplish his economic agenda by mid‐2022. Drawing on his powers and popularity, he may yet be able to elicit the full support of Congress.
Polypharmacy in schizophrenia
Authors: Baandrup Lone 
Published: January 2020

AbstractSchizophrenia is a severe mental disorder characterized by a heterogeneous symptom profile which comprises a clinical platform for widespread use of polypharmacy even though antipsychotic monotherapy is the recommended treatment regimen. This narrative review provides a summary of the current gap between evidence and practice for use of antipsychotic combination therapy in patients with schizophrenia. Antipsychotic polypharmacy is frequently prescribed instead of following international consensus of clozapine monotherapy in treatment‐resistant patients. Antipsychotic‐benzodiazepine combination therapy clearly has a role in the treatment of acute agitation whereas there is no evidence to support an effect on core schizophrenia symptoms when chronically prescribed. Antidepressants are typically added to antipsychotic treatment in case of persistent negative symptoms. Available evidence suggests that antidepressants may improve negative symptom control in schizophrenia. Combining an antipsychotic with an antiepileptic is not supported by any firm evidence, but individual mood stabilizers have come out positively in single trials. Generally, the evidence base for polypharmacy in schizophrenia maintenance treatment is sparse but may be warranted in certain clinical situations. Therapeutic benefits and side effects should be carefully monitored and considered to ensure a beneficial risk‐benefit ratio if prescribing polypharmacy for specific clinical indications.
