Abstract

Purpose

The purpose of this paper is to investigate the way informal groups rise and operate in the Teacher Association in a Secondary Vocational School Unit in Greece. More specifically, the way the role of the head teacher, the school culture and teachers’ emotional intelligence impacts these groups is investigated.

Design/methodology/approach

Qualitative research through in-depth interviews with teachers and the head teacher as well as the researchers’ participatory observation has been conducted, in order to support the selected method of the case-study.

Findings

The findings showed how both positive and negative informal groups rise and function in the Teacher Association. The role of the head teacher emerges as a very significant factor that influences the emergence and the preservation of such groups. The school culture has a bidirectional relation with the existence and quality of informal groups. Emotional intelligence also plays an important role in forming informal groups and in the quality of actions of these groups.

Originality/value

This study covers a significant gap in the international literature of group dynamics in a Teacher Association and provides practitioners with valuable insights regarding the underexamined factors that lead to the formation, operation and preservation of informal groups, the study of which can lead to the development of sophisticated scales of measurement of these dynamics by future researchers.

Abstract

We lead increasingly electronic lives, in which a significant part of our existence takes place online. The concepts of eGovernment, eCommerce, eHealth and eLiving are an indication of this development. Against this background, there is an ever growing urgency of thinking through the problem of building trust in an online context. This paper examines the contextual conditions which affect building trust online. It will be argued that different combinations of the contextual conditions of trust building will result in different views of the trust by the customer. Some of these combinations are better than others, and while a holistic approach would likely result in the best solution, it is not necessarily always within reach. Online trust building could be defined as a successful combination of four basic elements: reputation, technology, expertise and relationship. Unlike previous research, this study attempts to take all of these four key elements and the dynamics of their interconnections into account.

This study aims to report on an automatic deidentification system for labeling and obfuscating personally identifiable information (PII) in student-generated text.

Abstract

Purpose

This study aims to report on an automatic deidentification system for labeling and obfuscating personally identifiable information (PII) in student-generated text.

Design/methodology/approach

The authors evaluate the performance of their deidentification system on two data sets of student-generated text. Each data set was human-annotated for PII. The authors evaluate using two approaches: per-token PII classification accuracy and a simulated reidentification attack design. In the reidentification attack, two reviewers attempted to recover student identities from the data after PII was obfuscated by the authors’ system. In both cases, results are reported in terms of recall and precision.

Findings

The authors’ deidentification system recalled 84% of student name tokens in their first data set (96% of full names). On the second data set, it achieved a recall of 74% for student name tokens (91% of full names) and 75% for all direct identifiers. After the second data set was obfuscated by the authors’ system, two reviewers attempted to recover the identities of students from the obfuscated data. They performed below chance, indicating that the obfuscated data presents a low identity disclosure risk.

Research limitations/implications

The two data sets used in this study are not representative of all forms of student-generated text, so further work is needed to evaluate performance on more data.

Practical implications

This paper presents an open-source and automatic deidentification system appropriate for student-generated text with technical explanations and evaluations of performance.

Originality/value

Previous study on text deidentification has shown success in the medical domain. This paper develops on these approaches and applies them to text in the educational domain.

Abstract

Purpose

Conventional motion mechanisms in adaptive skins require rigid kinematic mechanical systems that require sensors and actuation devices, hence impeding the adoption of zero-energy buildings. This paper aims to exploit wooden responsive actuators as a passive approach for adaptive facades with dynamic shading configurations. Wooden passive actuators are introduced as a passive responsive mechanism with zero-energy consumption.

Design/methodology/approach

The study encodes the embedded hygroscopic parameters of wood through 4D printing of wooden composites as a responsive wooden actuator. Several physical experiments focus on controlling the printed hygroscopic parameters based on the effect of 3D printing grain patterns and infill height on the wooden angle of curvature when exposed to variation in humidity. The printed hygroscopic parameters are applied on two types of wooden actuators with difference in the saturation percentage of wood in the wooden filaments specifically 20% and 40% for more control on the angle of curvature and response behavior.

Findings

The study presents the ability to print wooden grain patterns that result in single and double curved surfaces. Also, printing actuators with variation in infill height control each part of wooden actuator to response separately in a controlled passive behavior. The results show a passive programmed self-actuated mechanism that can enhance responsive façade design with zero-energy consumption through utilizing both material science and additive manufacturing mechanisms.

Originality/value

The study presents a set of controlled printed hygroscopic parameters that stretch the limits in controlling the response of printed wood to humidity instead of the typical natural properties of wood.

Abstract

Purpose

This paper aims to develop a performance measurement (PM) system for fourth-party reverse logistics (RL). In this regard, it proposes simultaneous utilization of a procedural approach and hybrid use of existing performance frameworks.

Design/methodology/approach

The paper first describes fundamentals of RL and PM approaches in literature to build a basis for further discussion. It then carries out a systematic review of the literature on PM in RL to highlight current trends and approaches in this regard. At last, it develops a PM system for fourth-party RL by exploring relevant performance frameworks and by defining a procedure in detail.

Findings

The paper identifies the ongoing interest in development PM in RL, and the gap and the need for the development of comprehensive PM system for fourth-party RL. It also identifies the best approach is to use existing performance frameworks in literature and a procedural approach together as they complement each other rather than contradicting.

Research limitations/implications

The paper fills a gap in literature by developing a comprehensive PM framework for the fourth-party RL. The presented procedure is well suited to be used as part of strategic management process in any fourth-party RL organization. It forces users a top-down approach, from strategies to measures, so that a strong linkage is established in the process. When used together with the proposed PM framework, it guarantees a comprehensive and balanced PM system.

Practical implications

The paper identifies the need for the development of a PM framework as well as a measurement system for the fourth-party RL in the literature. In this regard, it develops a PM framework first, and then a procedure on how to implement it. As a result, users can effectively use them as a part of strategic management process of their organizations.

Social implications

The fourth-party RL is growing and very promising mode of RL for well-being of society, by offering a strong path to sustainable development in the midst of diminishing resources in the world. The existence of a well measurement system is crucial for the healthy operations and development of fourth-party RL organizations. The paper is offering a strong PM model in this regard.

Originality/value

The paper fulfills an identified need to study how to develop a PM system for fourth-party RL.

Abstract

Purpose

The aim of this study is to identify the distinctive features of the diaspora phenomenon through the aggregation and systematization of the business and management literature and propose a framework to apply in the future studies.

Design/methodology/approach

The two-step research was based on a combination of bibliometric analysis and a manual in-depth study of academic articles. Overall, 421 academic papers in management and business journals until 2019 year were analyzed.

Findings

The authors provide a new holistic insight on the role of national diasporas for business outcomes via the analysis and systematization of the extant diaspora research. They revealed four definition approaches and five main clusters in the diaspora literature that have three main directions of research as international marketing with the tourism management focus, the IB research and diaspora entrepreneurship studies. The authors cover these main research streams and their contribution to the development of a topic.

Research limitations/implications

The proposed framework including definition approaches and suggestions on the further research can serve as a foundation for future studies to investigate the diaspora phenomenon. The findings also are of practical value for firms whose attention is paid to the effective management.

Originality/value

To bring more clarity to the existing and future development of diaspora research, this paper improves the structuring of the overall diaspora literature through clarification of the existing definitions of diaspora, provision of the criteria qualifying someone to be identified as a member of a diaspora, as well as an analysis and systematization of existing diaspora research streams and suggestions for future research directions.
