Abstract

Today modern epoxy base materials for printed circuit board production are designed with properties which ensure high dimensional stability, resistance to chemical action, and increased glass transition temperature, in order to meet the stringent demands now encountered in electronics use. Polyfunctional epoxy resins and the appropriate hardener/accelerator compositions are in widespread, effective use in the design of superior laminates. The quality of the through‐hole plating for holes drilled in these improved materials will depend on various parameters, including those covered by three main complexes: base material, mechanical processing, and chemical processes used for treatment of the drilled hole. Special attention is paid in this paper to the resin recession phenomenon in terms of processing parameters.

Abstract

This paper reports on a method for in‐situ observation of the morphology and stability of electrochemically generated metal layers. This information is obtained by comparing topographical and kinetic data. The method is based on coulometric, microgravimetric and optical measurement performed in situ on vertically growing electrodes. Measurements are obtained simultaneously from the same surface area.

Abstract

Purpose

This study aims to examine how knowledge workers navigate affective challenges in Personal Information Management (PIM), specifically anxiety, frustration, dependence and loss of control while managing complex, high-volume information. It explores the adaptive PIM practices they employ to mitigate these challenges.

Design/methodology/approach

Using a qualitative phenomenological approach, 16 semi-structured interviews were conducted with knowledge workers. Thematic analysis was used to identify affective challenges and corresponding adaptive PIM practices.

Findings

Findings of this study describe four key affective challenges: anxiety about information loss and system failure, frustration with information overload and inadequacies in PIM practices, dependence on digital systems and loss of control over fragmented information. To address these, participants adopted adaptive PIM practices, including backup routines, prioritization, decluttering, structured organization and redundant storage solutions. These practices functioned as scaffolding, reducing emotional strain and enhancing control over personal information spaces.

Research limitations/implications

The study offers insights for designing PIM systems that address affective challenges, including automated backup prompts and decluttering tools and for workplace initiatives promoting PIM skill development to enhance productivity and well-being.

Originality/value

This study positions adaptive PIM practices as essential scaffolding that supports knowledge workers in managing the dual demands of functionality and emotional regulation within their information landscapes. By framing adaptive practices as scaffolding, the study contributes to a deeper understanding of how PIM skills and mastery address both the organizational and affective complexities faced by knowledge workers.

Abstract

Purpose

Hashish consumption is one of the most widespread public health concerns due to its extensive use and high prevalence. This study aims to investigate the association between illness perception and quality of life among hashish users, while also assessing the mediating role of coping strategies.

Design/methodology/approach

Male hashish users’ with a mean age of 37.9 years (SD = 12.3) were screened from public and private addiction and rehabilitation centers in Districts Peshawar, Kohat and Karak. Data were collected through the Brief Illness Perception Questionnaire, the World Health Organization Quality of Life scale and the Brief Cope scale to assess illness perception, quality of life and coping strategies. Stepwise regression and mediation analysis were performed.

Findings

The findings suggest that illness perception has a significant reverse association with quality of life (r = −0.16, p < 0.01). However, coping strategies have a significantly positive association with quality of life (r = 0.51, p < 0.01) while subcategories, that is, problem-focused, emotion-focused and active avoidance coping were not significantly associated with quality of life.

Practical implications

Lower quality of life increases vulnerability to illness perception, and effective coping strategies improve quality of life. This study emphasizes the importance of addressing illness perception and enhancing coping strategies in interventions aimed at improving the quality of life for hashish users.

Originality/value

This novel view provide valuable insights for developing targeted interventions that enhance the well-being of hashish users by addressing both their psychological and behavioral aspects.
