Abstract

To obtain the best moisture‐proof and most reliable protective coating for an amorphous silicon image sensor (A4 documents), three methods of coating and patterning processes and 15 types of resin classified into five kinds of materials were evaluated. Through this study, a screen‐printing method using silicone resin material cured under conditions of 150°C for 60 minutes to form a 60 µm thick protective coating film was selected because of the simplicity of its fabrication process compared with the other two methods. The a‐Si photodiodes were tested under conditions of 121°C‐2 atm. for 300 hours, −30°C to 100°C for 350 cycles and 85°C for 500 hours, and their characteristics were not negatively affected.

Abstract

Advanced laser micromachining techniques for a TFT‐LCD (thin film transistor‐liquid crystal display) module have been developed to repair various kinds of defects such as shorts, opens, and degraded TFTs. They have also been designed to analyse failures in the TFT‐LCD. The techniques are as follows: (i) The technique of zapping the excess metal: to repair short defects and/or to isolate the TFT being tested from the adjacent TFTs. This uses a pulse Xe or a Q‐switched YAG laser. (ii) Zapping, followed by the metal deposition technique: to repair open defects and/or to form electrical testing electrodes. This uses a Q‐switched YLF and an Ar ion laser. (iii) The technique of micro‐welding two metal lines separated by an insulating layer: to repair open defects. This uses a Q‐switched YAG laser. (iv) A separation technique utilised on a TFT‐LCD panel adhered with epoxy resin. This uses a pulse Excimer laser. (v) A micro‐annealing technique for a degraded TFT: to recover the TFT characteristics. This uses a Q‐switched YAG laser. Through the study described above, the authors have confirmed that these techniques are highly effective for obtaining TFT‐LCD modules without defects. The yield of TFT‐LCD modules may therefore be expected to improve.

Abstract

The inhibitive effect of some substituted phenyl n‐phenylcarbamates on corrosion of iron in 2N HCI have been studied using gaivanostatic polarization measurement. Studies carried out with different concentrations of the inhibitor indicated that the compounds act as a mixed inhibitor. The results indicate that the additives reduce the corrosion rate by way of adsorption through the oxygen atom of phenoxy group and nitrogen atom of NH group. The inhibitory character of the compounds depends upon the concentration of the inhibitor, as well as its chemical composition. The results of electrocapillary measurements are consistent with the electrochemical measurements. Thermodynamic parameters for absorption of inhibitors have been calculated and discussed.

Abstract

Purpose

This paper aims to review the mechanical characteristics of the robotic mechanisms developed for ultrasound examinations. This will help to extract those mechanical features which together can produce a design with superior functionality.

Design/methodology/approach

Following an introduction regarding ultrasound examination, this paper discusses the concept of robotic ultrasound imaging and classifies the mechanisms in terms of their power trains used for robotic and haptic devices which assist physicians to perform ultrasound imaging on patients. A set of mechanical characteristics which together can generate a superior design is also presented.

Findings

The present paper shows that the robotic devices developed so far can perform ultrasound examinations. Each design with its own advantageous characteristics, and their simultaneous implementation in a new design, will create a robotic device with improved performance.

Originality/value

This paper provides a detailed review of the developments of the robotic systems for ultrasound examinations and some guidelines for new designs with improved functionality.

Abstract

Purpose

The purpose of this paper is to test the brand elongation effect which is defined as the impacts of the aspect ratio of logo on consumers’ temporal property assessment and brand evaluation.

Design/methodology/approach

This paper provides a theory with experiments.

Findings

The brand elongation effect that strip-shaped logos can make consumers perceive temporal property longer than square-shaped logos has been testified with three pairs fictional logos and one pair real-life one. The valence of temporal property moderates the effect on evaluation of temporal property. The perceived temporal length mediated the shape effect on brand evaluation only when the temporal property is important (vs unimportant) for the product.

Research limitations/implications

This study only deals with the elongation effect of logos’ aspect ratio, without discussing the impact of color, angle/roundness or other graphic properties of logos on consumer attitudes.

Practical implications

This study not only provides empirical supports to update brand logos but also further illustrates that some subtle properties of logos can result in influences that are both significant and substantial.

Originality/value

This research enriches the literature of branding and metaphorical cognition. The findings of this study provide direct implications for brand managers to design logos and manage multi-shape brand logos.

Abstract

Purpose

This case study explores how universal design for learning (UDL)-informed online instruction modules developed during COVID-19 can better support student information literacy outcomes. This study will also examine how hybrid learning lends itself to UDL and may resolve some of the issues within library instruction.

Design/methodology/approach

This case study explores how a team of librarians at Utah State University developed three UDL-informed modules to support library instruction and hybrid learning during the height of the COVID-19 pandemic. A survey was sent to composition instructors to understand how they utilized the three new UDL-informed modules and if the modules helped their students reach information literacy outcomes.

Findings

Findings from this case study describe how academic libraries should adopt the UDL framework to support best practices for online learning as well as inclusive pedagogies. The findings indicate that the UDL-informed modules developed for hybrid instruction help students meet information literacy outcomes and goals.

Originality/value

The authors present a case study examining the current climate of information literacy instruction and UDL while providing actionable instructional practices that can be of use to librarians implementing hybrid instruction.

Abstract

Soil quality is in decline in many parts of the world, in part due to the intensification of agricultural practices. Whilst economic instruments and regulations can help incentivise uptake of more sustainable soil management practices, they rarely motivate long-term behavior change when used alone. There has been increasing attention towards the complex social factors that affect uptake of sustainable soil management practices. To understand why some communities try these practices whilst others do not, we undertook a narrative review to understand how social capital influences adoption in developed nations. We found that the four components of social capital – trust, norms, connectedness and power – can all influence the decision of farmers to change their soil management. Specifically, information flows more effectively across trusted, diverse networks where social norms exist to encourage innovation. Uptake is more limited in homogenous, close-knit farming communities that do not have many links with non-farmers and where there is a strong social norm to adhere to the status quo. Power can enhance or inhibit uptake depending on its characteristics. Future research, policy and practice should consider whether a lack of social capital could hinder uptake of new practices and, if so, which aspects of social capital could be developed to increase adoption of sustainable soil management practices. Enabling diverse, collaborative groups (including farmers, advisers and government officials) to work constructively together could help build social capital, where they can co-define, -develop and -enact measures to sustainably manage soils.

Abstract

Purpose

The purpose of this paper is threefold. First, to explore the importance of specific work environment facets for the overall job satisfaction (JS) of primary full-time permanent teachers (PTs) and substitute/temporary teachers (STs). Second, to highlight the similarity or difference in JS patterns among PTs and STs. Third, to provide guidelines for effective evidence-based human resource management (HRM) interventions targeting to boost PTs and STs JS levels by considering: (1) the perceived importance of individual work facets for them and (2) the school's performance in providing a satisfactory work environment.

Design/methodology/approach

Data on overall and important JS facets (i.e. satisfaction with opportunities for self-fulfillment, work intensity/load, salary/income, leadership and collegial relations) were collected from a sample of 438 PTs and STs in Greece. Moreover, MUSA, a method that combines Multi-Criteria Decision (MCDA) and Importance-Performance Analysis (IPA), was applied to uncover the critical work environment facets of PTs and STs overall JS that call for interventions.

Findings

The findings suggest that PTs seem to value, more than STs, the transactional and economic aspects of the school environment. More precisely, on the part of PTs, self-fulfillment and salary/income are the main contributors to their JS, whilst leadership is the least important facet of JS. For STs self-fulfillment and collegial relationships are the aspects of work that contribute the most to their overall JS, whilst salary/income is the least important contributor. The study results further indicate that self-fulfillment is the strong attribute of Greek schools' work environment in boosting TJS regardless teachers' status, whilst salary/income and workload are potential threats.

Originality/value

It is one of the few studies that provide insights into the differing JS patterns of STs and PTs through the application of a MCDA/IPA method. Therefore, it offers evidence-based guidelines that take into consideration both the school's performance (overall and facet JS) and importance of core aspects of the work experience for STs and PTs.

Abstract

Purpose

This paper aims to examine knowledge production and problem representation with regard to new psychoactive substances (NPS) in Her Majesty’s Chief Inspector of Prisons (HMCIP) annual reports.

Design/methodology/approach

Seven annual reports published by HMCIP for England and Wales between 2014 and 2020 have been systematically reviewed drawing on thematic analysis.

Findings

This paper demonstrates how framing in HMCIP annual reports produced a characterisation of NPS in prisons that inadvertently obstructed gender-sensitive knowledge production and problem representation. The framing formalised knowledge silences about spice in women’s prisons.

Originality/value

HMCIP annual reports monitor drugs in prisons and this affects how these spaces are represented to government and other stakeholders. This paper provides theoretical and practical insights into how gender-blind knowledge is produced by discussing examples of gender-blind drug representations in a specific policy context.

Abstract

Purpose

The purpose of this paper is to focus on how mental health professionals involved in the therapeutic treatment of children in public mental health facilities in Greece experience and talk about the impact of the socioeconomic crises on the psychotherapeutic process.

Design/methodology/approach

In all, 21 semi-structured interviews were conducted and phenomenologically informed thematic analysis was used in analysing the data.

Findings

The results coalesced into two all-encompassing thematic structures articulating the following: first, the socioeconomic crises have permeated society and therapeutic praxis like a torrential and chronic rain storm. This has resulted in a deluge in demand for therapeutic services within the public mental health sector; second, mental health professionals describe their positioning and work as “a constant tug-of-war” where they are inundated and often overwhelmed with work, find themselves identifying with service users and taking on several roles simultaneously, and being challenged to find solutions often in dire and complex situations. They describe how creativity and flexibility are in demand in their day-to-day interactions and if they are to intervene in place of a health and welfare system that is faltering. Doing therapeutic work under such circumstances appears to be both emotionally onerous and stimulating with regard to conceptualising new ways of intervening in such complex psychosocial situations.

Research limitations/implications

The study is limited in that only mental health professionals presented their experiences and service users were not included. The findings do highlight how severe austerity policies impact mental health services and peoples’ lives.

Practical implications

The study has implications for policy regarding the provision and organisation of mental health services in contexts where crises and economic turmoil prevail.

Social implications

The results associate severe austerity with major changes in family and community life.

Originality/value

The paper provides insights and implications on how mental health services are impacted by socioeconomic conditions.
