Being inherently a non‐pressure fusion process, laser‐beam welding (LBW) has been shown to have difficulty compared to resistance spot welding for weld‐bonding Al alloy structures, despite the many structural and manufacturing productivity advantages. Study of laser‐beam weld‐bonding of Al‐alloy structure for automobile assembly has led to a technique that appears to have both technical feasibility and production utility. The use of LBW through a hole in a pressure‐applying probe has proven to allow the production of contamination‐free spot welds through pre‐applied pre‐cured structural adhesive. The general approach, along with some details to still be overcome, is presented for both information and solution.

In the past, leadership scholars have tended to focus on leadership as a force for good and productivity (Ashworth, 1994; Higgs, 2009; Padilla, Hogan, & Kaiser, 2007). However, recently attention has been given to the ‘dark side’ of leadership (see Higgs, 2009; Judge, Piccolo, & Kosalka, 2009). The aim of this chapter is to explore dark leadership from the perspective of the narcissistic leader using a fictional character from a popular film.

Using the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, 1994 (DSM-IV) (American Psychiatric Association, 2000) as an operational definition of narcissistic personality disorder we explore the psychology of the narcissistic leader through a fictional character study in a popular film.

We have created a psychological profile of a narcissistic leader which identifies specific behavioural characteristics within a toxic organizational culture.

This study has implications for employees within any organizational culture. It is significant because it can illustrate how dark leadership can impact negatively within organizations.

The use of actual living persons on which to base case study material in the study of dark leadership is problematic and constrained by ethical issues. However, the use of characters in fiction, such as contemporary film and drama, represents an excellent source of case study material. Given that little empirical works exists on narcissistic leaders and leadership, the chapter adds originality and value to the field.

Pilot upgrade training is critical to aircraft and passenger safety. This study aims to identify variances in the US Air Force C-130J pilot upgrade training based on geographic location and provide a model to enhance policy that will impact future pilot training efforts that lower cost and increase operator quality and proficiency.

This research employed a mixed-method approach. First, the authors collected data and analyzed 90 C-130J pilots' aviation records and then contextualized this analysis with interviews of experts. Finally, the authors present a modified version of Six Sigma's define–measure–analyze–improve–control (DMAIC) that identifies and reduces the variances in C-130J pilot training, translating into higher quality outcomes.

The results indicate significant statistical variances across geographically separated C-130J pilot training organizations. This leads some organizations to have higher proficiency levels in specific tasks and others with comparative deficiencies. Additionally, the data analysis in this study enabled a recommended number of flight hours in several distinct categories that should be obtained before upgrading a pilot to aircraft commander to enhance standards.

This research was limited to C-130J pilot upgrades, but these results can be implemented within any field that utilizes hours as a measure of experience. Implications from this research can be employed to scope policy that will influence pilot training requirements across all airframes in civilian and military aviation.

This research proposes a process improvement methodology that could be immediately implemented within the C-130J community and, more importantly, in any upgrade training where humans advance into higher echelons of a profession.

The purpose of this paper is to examine situations in which brand extensions are likely to dilute beliefs associated with family brands.

Hypotheses are developed and tested in a consumer survey that included experimental and control groups.

The findings show the congruity of the extension with the family brand is an important factor, the absence of which increases the chances of dilution of the family brand. Perceived success/failure of the extension is a more important factor that also enhances or dilutes the image of the family brand.

Brand names can be hurt by brand extensions, which contain attributes incompatible with or negating favorable family brand beliefs.

If managers feel the dilution is occurring because of an extension, they can increase perceptions that the extension is atypical of the family brand.

This paper identifies certain key attributes of extensions that, if ignored, may dilute the image of the family brand.

With so many academic librarians now employed in split or multi‐task job assignments, those who teach may question how they can develop the skills they need to be challenging and innovative in the classroom. Instruction librarians may turn to their colleagues to help them cultivate their teaching skills, particularly during times when bibliographic instruction (B.I.) workshops or training sessions are not imminent. Noticing the informal coaching that exists among trusted colleagues, some libraries have given structure to this exchange through peer coaching programs.

The study attempted to gauge the relative effectiveness of celebrity and product image match-up in comparison to non-celebrity attractive endorsers for two distinct high involvement situations. Also, due to the expected demographic diversity among target consumers, the study aimed at assessing the impact of respondent's age and gender on the effectiveness of image match-up.

Building on the three-order hierarchy model, two experiments were conducted (utilising celebrity and non-celebrity endorsers) for two high involvement hierarchies, i.e. standard learning and dissonance/attribution. Through fictitious print advertisement, the experiments assessed the effectiveness of the match-up in terms of consumer attitudes towards advertisement and brand and intentions to purchase.

The match-up consistently and significantly outperformed non-celebrity attractive endorser in case of standard learning hierarchy. The same conclusion was not established for dissonance/attribution hierarchy due to the lack of significant results. The findings also suggest that the match-up subdues the impact of consumer's gender and age on consumer attitudes only in case of standard learning hierarchy.

The study provides interesting theoretical implication by challenging a widely held postulation about the applicability of celebrity and product match-up under high involvement.

The research provides the practitioners with a better understanding of important issues, mainly, whether to use a celebrity endorser and selecting the right celebrity, especially if high involvement is expected.

Previous research concerning celebrity endorsements has largely considered consumer involvement as unitary, i.e. either high or low. However, the multifaceted aspect of consumer involvement is well established in the field of consumer psychology. The present research, therefore, is a pioneering attempt as it studies the effectiveness of match-up for two distinct high involvement situations. Moreover, unlike the majority of previous studies that have focused on the performance of “celebrity match” versus “celebrity mismatch”, the impact of match-up was studied in comparison to a non-celebrity attractive endorser.

This paper aims to explore the prevalence of depression, anxiety symptoms and suicidal ideation among the Romani population in Ukraine and their connections with various social health determinants: age, gender, household characteristics, employment and living conditions.

For measuring mental health conditions, GAD-7 and PHQ-9 were used. Individual interviews were conducted by trained volunteers of the International Charitable Organization “Roma Women’s Foundation Chirikli”. Data were gathered from January to March 2020.

The overall level of depression found in the sample was 8.08, while the mean for anxiety was 7.22. In general, 32.7% of respondents scored positively for signs of depression and 29.6% for anxiety. The two-week prevalence of suicidal ideations was 26.9%. Compared to the general population, the prevalence of depression among the Romani research participants was twofold higher, and anxiety was 2.5-fold higher. Signs of depression and anxiety in women were significantly higher (36% vs 28.6% for depression and 33.9% vs 24.2% for anxiety) than in men. Signs of depression and anxiety were higher for people without education than for university students (9.32 vs 3.04 for depression and 8.26 vs 3.00 for anxiety). The lowest levels of depression, anxiety and suicidal ideation were among officially married persons (6.61, 6.36 and 0.23, respectively). Significant small positive correlations were found between all measurements and the number of household members (0.149 for depression, 0.124 for suicidal ideation and 0.175 for anxiety; p < 0.001) and the number of children (0.303 for depression, 0.224 for suicidal ideation and 0.243 for anxiety; p < 0.001). In terms of employment, the highest scores for depression, anxiety and suicidal ideation were found among those who are employed seasonally (9.06, 8.25 and 0.61) or irregularly (9.09, 8.12 and 0.57) in contrast with self-employed (4.88, 4.90 and 0.19) and full-time employees (5.86, 5.51 and 0.18). Living place (city, village or camp) showed no relation with mental health, except for suicidal ideation: those living in villages had higher levels of suicidal ideation than those living in cities (0.49 vs 0.31).

The study has some limitations. Data were gathered from January to March 2020, and since then, the situation in Ukraine has drastically changed due to the full-scale Russian invasion. While this study’s data and conclusions might serve as a baseline for further research, they do not represent the real-time situation. While many social factors were analysed, the effects found for them do not necessarily represent causality, given the statistical methods used. Interactions among factors were not studied; therefore, no firm conclusions can be made about the effects of those interactions on mental health.

To the best of the authors’ knowledge, this paper is original in terms of its topic, as the first-ever in Ukraine quantitative study of mental health and social determinants of mental health of the Romani population.

From the standpoint of a policy maker who has access to a number of expert forecasts, the uncertainty of a combined or ensemble forecast should be interpreted as that of a typical forecaster randomly drawn from the pool. This uncertainty formula should incorporate forecaster discord, as justified by (i) disagreement as a component of combined forecast uncertainty, (ii) the model averaging literature, and (iii) central banks’ communication of uncertainty via fan charts. Using new statistics to test for the homogeneity of idiosyncratic errors under the joint limits with both T and n approaching infinity simultaneously, the authors find that some previously used measures can significantly underestimate the conceptually correct benchmark forecast uncertainty.

The goal of this paper is to examine how broadcaster brand images are affected by programming decisions.

Two sets of experiments were undertaken with regular viewers/listeners of TV and radio stations. Subjects were presented with scenarios describing program success (failure) and program congruity (incongruity).

Results show that perceptions of program brand success (failure) have an enhancement (dilution) effect on broadcaster brand image. Program familiarity intensifies these effects. Results also show that congruity (incongruity) of program brand image produces enhancement (dilution) effects on broadcaster brand image.

Program success and congruity are conceptually and empirically linked to broadcaster branding. Further work is required to examine the drivers of success and congruity.

Results are of direct relevance for those managing broadcaster brands. They need to be aware that perceptions of a broadcaster can be enhanced (diluted) when viewers/listeners are exposed to evidence of (a) successful (unsuccessful) programs and (b) congruous (incongruous) programs. This calls for active management of perceptions of success and congruity.

This is one of only a small number of papers in marketing to focus on the commercially important area of broadcaster branding. It highlights issues that are of significance for broadcasters and for those in communications and entertainment more broadly.

The purpose of this paper is to present a language-agnostic approach to facilitate the discovery of “parallel passages” stored in historic and cultural heritage digital archives.

The authors explore a novel, and relatively simple approach, using a character-based statistical language model combined with a tailored version of the Basic Local Alignment Tool to extract exact and approximate string patterns shared between groups of documents.

The approach is applicable to a wide range of languages, and compensates for variability in the text of the documents as a result of differences in dialect, authorship, language change over time and errors due to inaccurate transcriptions and optical character recognition errors as a result of the digitisation process.

A number of case studies demonstrate that the approach is practical and generalisable to a wide range of archives with documents in different languages, domains and of varying quality.

The approach described can be applied to any digital archive of modern and contemporary texts. This makes the approach applicable to digital archives recording historic texts, but also those composed of more recent news articles, for example.

The analysis of “parallel passages” enables researchers to quantify the presence and extent of text-reuse in a collection of documents, which can provide useful data on author style, text genres and cultural contexts.

The approach is novel and addresses a need by humanities researchers for tools that can identify similar documents and local similarities represented by shared text sequences in a potentially vast large archive of documents. As far as the authors are aware, there are no tools currently exist that provide the same level of tolerance to the language of the documents.
