Abstract

Polymer thick film (PTF) technology provides the lowest cost, cleanest and most efficient manufacturing method for producing flexible circuits. Non‐contact radio frequency (RF) smart cards and related information transaction devices, such as RFID tags, appear to be a good fit for PTF‐flex. Flip chip also seems well suited for these “contactless” RF transceiver products. Flip chip and PTF adhesive technologies are highly compatible and synergistic. All PTF SMT adhesives assembly methods are viable for flip chip. However, the merging of flip chip with PTF‐flex presents major challenges in design, materials and processing. This paper will compare assembly methods and discuss obstacles and solutions for state‐of‐the‐art flip chip on flex within the RFID product environment.

Abstract

Some of the unique changes impacting on management development throughout the world are explored and some of the creative responses which have been developed by several centres of management in reaction to these changes. Articles are briefly summarised and the reasons for their inclusion explained.

Abstract

Purpose

The purpose of this study is to determine the viability of Lacticaseibacillus rhamnosus GR-1 (L. rhamnosus GR-1) in five yogurt samples with or without quinoa, chickpea, soybean and rice flour over various fermentation periods and refrigerated storage durations, with a focus on exploring the potential of functional foods, which provide health benefits beyond nutritional value. Additionally, the study aimed to evaluate consumer acceptance of yogurt fortified with functional flour. Using a nine-point hedonic scale, from 1 (dislike extremely) to 9 (like extremely), participants rated appearance, flavour, texture and overall acceptability.

Design/methodology/approach

The samples were inoculated with the probiotic strain L. rhamnosus GR-1 and fermented for 0, 2, 4 and 6 h at 38°C, followed by refrigerated storage at 4°C for 1, 15 and 30 days, respectively. Microbial enumeration was performed throughout fermentation and storage to assess the viability of L. rhamnosus GR-1. A sensory evaluation involving 86 participants was conducted to assess the consumer acceptability of the yogurt samples.

Findings

Notably, L. rhamnosus GR-1 achieved viable counts of 108 colony-forming units per mL in all treatments at all fermentation time points. Over the 30-day storage period, no statistically significant differences (p < 0.05) in average pH values were observed among the five treatments, and within each treatment, pH levels remained stable, with an overall mean of 4.2 ± 0.64. Treatment 4, which featured rice flour fortification, received higher hedonic scores from sensory panellists in terms of appearance, flavour, texture and overall acceptability. These findings indicate that incorporating functional flours in conjunction with cow’s milk effectively promotes and preserves the viability of L. rhamnosus GR-1 in yogurt.

Originality/value

Exploring the potential of probiotic yogurt enriched with diverse functional flours to enhance nutritional content and health benefits as well as attract new consumers, this study addressed a critical gap in understanding consumer perceptions and generated insights for creating innovative and health-promoting dairy products.

Abstract

Purpose

This paper aims to assess the empirical utility and conceptual significance of distributed leadership.

Design/methodology/approach

Three main sources of evidence are drawn on. The paper reviews some neglected commentary of an early generation of distributed leadership theorists. It also discusses a strand of social science writings on emergent small number management formations. An alternative interpretation of the findings of three recent empirical studies of distributed leadership is provided. Some unresolved issues are considered.

Findings

Distributed leadership arose in reaction to understandings of leadership that emphasised heroic‐like individual behaviour. It has achieved a high level of theoretical and practical uptake. This paper, however, argues for reconsideration. Distributed leadership is shown to be largely unremarkable, especially in light of the continuity between current writings and those of early generation scholars. This claim is also reinforced by the inability of most current scholars to develop the emergent potential of a tradition of writings on the division of labour in small groups (emanating mainly from the work of Georg Simmel). Finally, the paper argues that a more appropriate descriptor for recent leadership analyses may be “hybrid”, rather than “distributed”.

Originality/value

Conceptually and empirically, there is still work to do. First, leadership's distributed status now aligns it with power and influence, each for some time recognised as distributed, although the preference for leadership as a vehicle of analysis ahead of power and influence still lacks sufficient justification. Second, while distributed leadership is sometimes thought of as synonymous with democratic organisational leadership, the latter is shown to be conceptually distinct.
