Abstract
The surface mount technology (SMT) assembly process for 0.4 mm pitch chip scale package (CSP) components was studied in this work. For the screen printing process, the printing performance of different solder pastes, aperture shapes and sizes was investigated. Square apertures and a fine particle size in the solder paste provided a better paste release. Besides optimising the printing process capability and minimizing the printing defects such as bridging and missing paste, the total volume of solder consisting of the paste and the solder ball has to be considered in order to maximize the final process yield. For the pick & place process, the accuracy required for the placement equipment was determined by studying the self‐alignment of the lead‐free CSPs (with Sn/4.0Ag/0.5Cu balls) during the reflow process using lead‐free Sn/3.9Ag/0.6Cu paste. The components were intentionally misplaced up to ∼50percent off‐pad. After reflow, x‐ray inspection showed that the components had aligned to the pad. By considering the stack‐up of the printed circuit board pad location and size tolerances, the solder paste printing tolerances and the placement tolerances, the required alignment accuracy for the pick & place equipment was established to meet the total process capability requirement.

Abstract
In a largely exploratory study, the authors investigate: how do managers’ experiences with exogenous hazards (e.g., natural disaster risk) affect their identification of those hazards as salient to the firm? This analysis is based on an international survey of 575 managers across 18 disaster-prone countries. The authors examine whether and how locational hazard risk and managerial experience influence the identification of natural disaster risk as an important firm issue. The authors find that locational natural hazard risk, and direct and indirect experience with natural disasters, increases the likelihood that managers’ will identify firm-specific natural disaster risk as an important firm issue. In addition, the authors also find that managers are likely to identify natural hazards as a threat when natural hazard risk is high and when managers have experience in natural disasters that directly affected their businesses.

Abstract
Purpose
The purpose of this paper is to describe and analyze how the Swedish Association of Biology Teachers (ABT) and some other subject associations helped form pre-service biology teacher education in two major Swedish reforms from ca. 1960 to 1990.
Design/methodology/approach
The activities of subject associations can be understood as boundary-work since they defend their subject boundaries in terms of content, space in the timetable, and legitimacy. A hermeneutic method of text interpretation is employed in analyzing historical archival and parliamentary material.
Findings
The work of the ABT to demarcate their subject in the 1968 and 1988 Teacher Education Reforms may seem like merely defending certain biological items instead of others, in the name of science. However, it was also a professional struggle to assert the importance of the teachers, their jobs, education, knowledge of biology subject matter, and thereby their professional authority and autonomy. The ABT were also caught in a political struggle for their subject throughout the period of investigation. Depending on the political winds of the time they therefore had to ally themselves with or distance themselves from various actors.
Originality/value
In comparison with the few other studies of subject associations, this paper is unique in outlining how the ABT acted in relation to teacher education. However, the ways of doing boundary-work were still very similar to those used by subject associations in schools in other countries, especially in acting for increased study time in their respective science subjects as well as their resistance to subject integration. An obvious conclusion regarding teacher education is that subject associations such as the ABT did not contribute to bridging the gap between subject matter and pedagogy but rather the opposite. Biology teacher education was seen as an academic pursuit carried out at universities rather than at the practically oriented teacher training colleges.

Abstract
Purpose
The Indirect Leadership Questionnaire (ILQ) is constructed to measure important parts of a theoretical model of indirect leadership to be used in leadership courses for high-level managers. The ILQ consists of 15 model-derived items plus extra space that provides for free-text comments. This study aims to evaluate the psychometric properties of the ILQ, its predictive power and practical usefulness in indirect leadership courses and to evaluate the indirect leadership model in the light of new data.
Design/methodology/approach
The study sample consisted of 225 higher managers and 6–10 of their subordinates (total: 1,703). The latter were working at least two hierarchical levels below their higher manager. The managers made self-ratings, and the subordinates rated their respective higher manager using the ILQ.
Findings
Results showed that the ILQ has acceptable psychometric properties in terms of dimensionality (two model-compatible factors were obtained), reliability, discriminability and predictive power. Previous problems with many “Don’t know” responses from subordinates working two or more hierarchical levels below their higher manager were considerably reduced. A qualitative analysis of the free-text responses showed that indirect leadership behaviors that can be seen as inspirational influence and communication skills should be more emphasized in future indirect leadership courses. The leaders’ personality, task-related competence and performance-orientation were also highlighted more than in the indirect leadership model.
Research limitations/implications
It was concluded that the ILQ is a useful tool in indirect leadership courses but that it is too limited to be used as a basis for theory development of indirect leadership.
Originality/value
The ILQ has acceptable psychometric properties and provides an easy-to-use tool to gain practical, usable knowledge of the “how’s” of indirect leadership.

Abstract
Purpose
The aim of this study is to investigate older people's perceptions, across eight European countries (the UK, Denmark, Germany, Poland, Portugal, Spain, Sweden and Italy), towards functional foods.
Design/methodology/approach
The repertory grid method was used to elicit reasons underlying preferences of five yoghurts with different functional properties and two conventional ones.
Findings
Familiarity was the key driver in products' separation. For the Italian case, as well as the Spanish, Portuguese, Danish and Swedish the first principal axis could be interpreted as novel‐common axis, whilst it was not in the UK, Germany and Poland.
Research limitations/implications
Behavioural intention to buy functional yoghurts was more strongly predicted and moderated by single item perceived need (PN) than single item affective and/or cognitive attitude (AA, CA), even though PN, AA and CA could be consistently assessed within the same latent measure (in all countries but Denmark). Nevertheless, beliefs/attitudes towards a novel category of products such as functional foods may be reasonably keeping moving.
Originality/value
In this study, preference instructions pertaining to beneficial and imagery attributes, revealed idiosyncratic properties associated with functional yoghurts across eight European samples of older people.

Abstract
Purpose
This paper offers an approach for outlining the main dimensions surrounding clusters in three areas of knowledge: economic geography, strategic management and operations management, the first being considered its natural field of knowledge.
Design/methodology/approach
The work was developed using the citation analysis technique as applied to a database of 627 articles and 22,980 citations, taken from 15 important journals in the areas selected.
Findings
The results proved that the theoretical and conceptual bases are unique to each of the areas studied and that they have few topics in common between them. They are complementary, however, and this facilitates their reconciliation.
Research limitations/implications
The sample base, despite considering fairly influential periodicals in the areas of knowledge selected, can be considered to be a limitation.
Originality/value
Common themes and different areas of knowledge surrounding the cluster concept were identified; despite being considered “common”, a more detailed examination of their content reveals very different, but certainly complementary emphases, which makes it possible to reconcile the areas of knowledge.

This paper examines whether following a health crisis the use of health and safety protocols and hotel brand awareness influences hotel perceived value and intention to visit.
Abstract
Purpose
This paper examines whether following a health crisis the use of health and safety protocols and hotel brand awareness influences hotel perceived value and intention to visit.
Design/methodology/approach
Using an experimental design, the study evaluates the effectiveness of the use of health and safety protocols and the moderating effect of brand awareness on perceived value and intention to visit.
Findings
The results show that the hotels using health and safety protocols (compared to those that do not use them) will achieve a higher perceived value and intention to visit. In addition, the awareness of brand does not moderate the effect of the health and safety protocols on perceived value and intention to visit.
Practical implications
This research identifies mechanisms for future consideration by hotel companies to promote the recovery of their activity after a health crisis. Specifically, using health and safety protocols will result in the market evaluating the brand more highly and produce a greater intention to visit. At the same time, the research indicates that regardless of whether the brand is well-known or not, the use of a health and safety protocol is advantageous.
Originality/value
This study offers new insights that can be useful for developing a resilient hotel sector in the face of future health crises. Specifically, the results show progress in understanding the effects that the use of health and safety protocols and brand awareness have on key consumer variables for the recovery of the sector in a post-pandemic context.

Abstract
Purpose
The purpose of this paper is to examine the problem of deforestation in Amazonia and the role of the Brazilian government with regard to the capitalist demands and development needs for the region. It offers a brief historical review of public policies and programs for Amazonia, and critically analyzes their conflicting aspects. Local environmental governance (LEG) is proposed as a conceptual framework and a participatory forest management strategy for dealing with the forest destruction.
Design/methodology/approach
The paper is a qualitative‐based study which provides a systemic analysis of the process of occupation and the key public policies for Amazonia from over the last decades, particularly during the coup d'état regime. Based on a literature review and official documents, descriptive data are produced which helped in understanding the political phases of the Brazilian government administrations.
Findings
The study identified some participatory‐based, decentralized models of forest management and existing forest regulatory frameworks which can serve as an illustrative sketchy arrangement on how local environmental governance can become operative and serviceable for a sustainable balance between the use of natural resources, conservation and regional planning. These findings can help future investigations on governance models. The research also shows how the Brazilian government has perceived Amazonia throughout the decades and how this perception influenced the implementation of development and settlement policies for the region.
Originality/value
The main focus of this article is the debate on the concept of local environmental governance (LEG) as a tool for empowering the local communities through the decentralization of decision making as well as the attempt to find implemented normative and institutional structures within the Amazonian context which can translate aspects of LEG.
