Silver‐glass die attach materials represent a significant advance in silicon packaging technology and are expected to displace gold‐silicon eutectic bonding as the preferred method of die attachment for high reliability applications. In this paper the rle of the glass in the adhesion mechanism of silver‐glass to gold and chromium/gold backed die has been determined using thermal analysis and X‐ray diffraction in addition to scanning electron microscopy and electron probe microanalysis of the sintered film. An adhesion mechanism is proposed in which the glass of the silver‐glass system migrates to the die interface during the firing cycle and chemically bonds to the silicon which is present at the surface of the gold‐silicon eutectic. Adhesion between the die back and the silver of the die attach material is by means of a simple mechanical bond between ‘fingers’ of glass and the sintered silver matrix. Thermodynamic and kinetic considerations suggest that insufficient silicon dioxide may be formed using chromium/gold backed die for acceptable adhesion. Processing changes are proposed which resolve this adhesion problem.

ISHM (UK) presented a technical meeting on this topic on the 23rd October 1982 at the Cunard International Hotel, London. The meeting was attended by some 50 engineers, both those involved in the field of hybrids and potential users. It was generally felt that this was a useful meeting but more especially that it would have appealed to many potential users of hybrids, had the right people been able to be contacted.

Under the agreement, Maquinaria Suiza will be the sole supplier of the highly successful product range to Spain and Portugal.

Despite the undeniable need for innovation in hospital building design, the literature highlights the disconnect between research and practice as the primary knowledge gap hindering such innovation. This study shows this focus to be an oversimplification, for the complex processes that trigger design innovations and impact their ecosystems need to be examined from a systemic perspective. This paper aims to conceptualise the evolution of hospital building design and identify and explain the main factors triggering design and construction innovations over the past 100 years.

A novel hybrid research design to mixed grounded theory (MGT) methodology, with Charmaz constructivist paradigm, is developed as a new systematic way of constructing and interpreting the concepts and interconnections among them that triggered design innovation.

This study represents a taxonomy of concepts and an explanatory innovation framework, containing 617 interconnections between 146 factors classified across 14 categories. The complex innovation ecosystem comprises multi-faceted processes between heterogenous factors with both individual and collective impacts on design innovations.

This research highlights the main components of the innovation ecosystem and its overall behaviour in this field, and the most influential and interrelated contextual factors, as well as representing and mapping generative interactions that support innovation processes. This knowledge can help hospital researchers, designers, policymakers and stakeholders adopt a multidimensional outlook to analyse the strength of all influential factors, introduce potential novel ways of collaborating, conceptualise an organisational approach, re-formulate research questions through transdisciplinary methods and introduce interdisciplinary courses and programs in architecture schools, thereby contributing to timely design innovation.

Intergroup contact is crucial for social cohesion, especially in metropolitan cities. However, in segregated cities, public spaces are challenged by the division between different social groups and the tension associated with their mutual presence. While several studies assure the value of intergroup contact, very few inform urban designers on how to create spaces that overcome segregation and allow positive encounters. This paper investigates one of the public spaces of intergroup contact: Digla Square, in Cairo, Egypt.

The paper first develops an interpretive framework to investigate intergroup contact in segregated cities. Afterwards, it uses that framework to approach Digla Square for the case study. The methods used to collect data from the field included unstructured observations and in-depth, semi-structured interviews with representatives from all social groups encountering the square.

Coding the collected data relying on constructivist grounded theory identified three themes: Digla Square as a place to live, work and play; to appropriate and personalize and to build a common community character. Discussion of the findings reveals an explanation of the phenomenon and draws on connecting the identified themes to existing urban theories.

The paper affords an innovative approach to studying intergroup contact in segregated cities. It also provides a practical framework for empirical and/or field study and the analysis of the results. Moreover, the paper proposes a new perspective towards understanding the phenomenon of intergroup contact in public spaces in metropolitan cities. Lastly, it specifies more human-centred insights for urbanists towards better place-making for their public spaces.

This paper investigates the impact of social-media marketing elements, namely entertainment, customisation, interaction, electronic word-of-mouth (EWOM) and trendiness, on consumer–brand engagement and brand knowledge.

Using an online survey, the study collects data in Hong Kong from 214 experienced social-media users, as indicated by their consumption of a durable technology product, a smartphone. We used partial least squares structural equation modelling (PLS–SEM) to test the links between social-media marketing elements, consumer–brand engagement and brand knowledge.

The results reveal that interaction, electronic word-of-mouth and trendiness are the key elements directly influencing consumer brand engagement, then strengthening brand awareness and brand knowledge. This contrasts with the non-significant results found for the influence of entertainment and customisation on consumer–brand engagement.

Having cross-sectional nature, the study focuses on one single product, smartphones, at one location, Hong Kong. Future research may enhance the generalisability of the findings by replication in other countries with diverse cultures, such as countries in Latin America and Africa and examine other industries and other products, such as the service sector and convenience products with a low involvement level.

Marketers may strengthen consumer–brand engagement by using content that is trendy, along with encouraging interaction and positive EWOM on social-media platforms, in order to build strong and positive brand knowledge in consumers' minds.

This study contributes to the branding literature by providing an understanding of the role of social-media marketing elements in the brand-building process. Social media is a marketing channel recognised by its effectiveness in communicating brand-related information and its role as a means to stimulate consumers' brand engagement and brand knowledge. However, how effective these elements are for these purposes remains to be established. By empirically testing a theoretical model, this study confirms that specific social-media marketing elements, namely interaction, EWOM and trendiness, are critical drivers in the brand-building process in Hong Kong.

The purpose of this paper is to analyze the temporal development of noncognitive abilities of children and the development trajectory of rural and urban children's noncognitive abilities in China.

Lexis diagram is used as the research framework to depict the development trajectory of rural and urban children's noncognitive abilities in China. By employing the nationally representative longitudinal survey data, China Family Panel Studies (2010–2016), the difference of rural and urban children's noncognitive abilities is disentangled into temporal, age and cohort effects.

There is a significant temporal rural–urban difference in children's noncognitive abilities, but the rural–urban gap would expand, narrow or show more complex development trends under different measurements. The results of age and cohort comparison are similar to those of temporal comparison, that is, there are divergent trajectories of rural–urban gap due to the different measurements and different ages and/or cohorts. Specifically, urban children perform better in self-esteem, but rural children always have a higher social responsibility, such a contrast between urban children's weak social responsibility under the advantageous condition and rural children's strong social responsibility in the relatively disadvantageous environment.

Children's noncognitive ability is not innate but is a gradually acquired characteristic through training and cultivation. The rural–urban difference of children's noncognitive abilities implies educational issues concerning educational principles in the urban environment and the educational resources' allocation in the rural society in China. Besides, as the unidimensional measurement of children's noncognitive ability is insufficient, the systematic measurement composed of multidimensional indicators utilizing cohort data or longitudinal data would be needed.

Driving for work has been identified as potentially one of the riskiest activities performed by workers within the course of their working day. Jurisdictions around the world have passed legislation and adopted policy and procedures to improve the safety of workers. However, particularly within the work driving setting, complying with legislation and the minimum safety standards and procedures is not sufficient to improve work driving safety. This chapter outlines the manner in which safety citizenship behavior can offer further improvement to work-related driving safety by acting as a complementary paradigm to improve risk management and current models and applications of safety culture.

Research on concepts associated with risk management and theoretical frameworks associated with safety culture and safety citizenship behavior are reviewed, along with their practical application within the work driving safety setting. A model incorporating safety citizenship behavior as a complementary paradigm to safety culture is proposed. It is suggested that this model provides a theoretical framework to inform future research directions aimed at improving safety within the work driving setting.

Problem 1 of the International Workshops for Eddy Current Code Comparison is a hollow cylinder with axis perpendicular to a uniform field. A total of 17 solutions are described and compared with experimental results. Many kinds of codes, both two‐ and three‐dimensional, were found to give satisfactory solutions.

Those most socially disadvantaged are at a greater risk of common mental disorder (CMD). The need to evaluate the health impact of social policy interventions that aim to reduce social inequalities between the disadvantaged and the better off is well recognised. This paper reports findings from a review to explore evidence on the health impact of UK policy interventions that aim to tackle the key social determinants of CMD. These were previously identified from the literature as cumulative socioeconomic deprivation, unemployment, psychosocial work characteristics, and poor social relationships. We identified some evidence of a positive impact on CMD of urban regeneration schemes, but evidence was sparse on interventions relating to the other determinants. The ability of research to inform policy designed to improve the lives of the disadvantaged could be assisted by a broader definition of what counts as evidence. This may include wider use of qualitative methodologies and a more deliberate focus on social processes known to be implicated in mental health.
