Abstract
Purpose
For any given customer, his/her profitability for a business enterprise can be estimated by the so-called customer lifetime value (CLV). One specific goal for many enterprises consists in maximizing the aggregated CLV associated with its set of customers. To achieve this goal, a company uses marketing resources (e.g. marketing campaigns), which are usually expensive.
Design/methodology/approach
This paper proposes a formal model of the Customer Life Value problem inspired by the uncapacitated facility location problem.
Findings
The computational experiments conducted by the authors illustrate the potential of the approach when compared with a standard (non-algorithm-supported) one.
Originality/value
The approach leads up to the economic trade-off between the volume of the employed resources and the aggregated CLV, i.e. the higher the number of resources utilized, but also the higher the cost of achieving this level of lifetime value. Hence, the number of resources to be “activated” has to be decided, and the effect of each of these resources on each CLV will depend upon how “close” the resource is from the corresponding customer (i.e. how large will the impact of the active resource on the customer).

Abstract
This chapter analyses the pilot episode of the ABC TV series Charlie's Angels (Spelling & Goldberg, 1976–1981) and the latest film of this media franchise, Charlie's Angels (Banks, 2019). The chapter undertakes an analysis of the three main characters in the series pilot and the three starring roles in the film, applying methodologies proposed by the cinematic poetic formalism (Bordwell & Thompson, 2006) and observing specifically the roles and motivations of these six women from a feminist perspective. On the one hand, the TV pilot engages with several of the main premises of the second-wave feminism that was in full swing at the time the series was released. On the other hand, the 2019 film was launched in the contemporary era of post-feminism, reflecting a number of the concerns that shape the post-feminist agenda. However, the main argument of this chapter is that both the series pilot released in 1976 and the 2019 film construct ambivalent feminist narratives. The analysis reveals that the Charlie's Angels franchise fluctuates between characteristics that can be labelled as feminist discourses, but also as replicators of a patriarchal model. Forty-six years later, while a few things have changed for the Angels, we argue that the characters and franchise have not lived up to its potential as a transformative feminist text.

Abstract
Purpose
The paper is aimed to obtain a clear understanding of influence factors that can increase the possibility to be business angels (BA).
Design/methodology/approach
This study develops the 3A model in the Chinese context to design questionnaire, and 334 questionnaires are obtained via focus group sample and targeted snowball approach, and the multinomial logit analysis is used to test a serious of hypotheses.
Findings
The paper confirmed that the entrepreneurial experience and wealth are determinants of investment for potential BA, and the wealth have both directly and indirectly positive influence on investment activity through risk preference, namely that richer people prefer risk which impel them to invest as BA.
Research limitations/implications
There are two limitations in the paper: first, the macro environment in China has not been taken into consideration in the model; second, the source of the sample focuses on the developed cities in the middle and eastern of China, only reflect the characteristic of angels in these areas, which may somewhat diverges from the reality.
Practical implications
The paper would contribute to form the policy which could promote the development of angel investment in China.
Originality/value
This paper conducts a preliminary exploration of the factors that have impact on Chinese BA' investment activity based on current research.

Abstract
The present article takes a qualitative approach through interviews with Spanish managers to identify the challenges they face while leading small- and medium-sized companies (SMEs) in China. They share with us their experiences with the state bureaucracy, local employees and the market place. Based on these interviews, I developed a model of leadership named agile leadership. Developing the qualities of an agile leader is a critical success factor for the SME manager in China. This model is explained and some tips are given to develop the qualities of an agile leader.

Abstract
Purpose
One of the main advantages of the proposed model is that it is flexible to generate n-day pairings simultaneously. It means that, despite previous researches, one-day to n-day pairings can be generated in a single model. The flexibility in generating parings causes that the proposed model leads to better solutions compared to existing models. Another advantage of the model is minimizing the risk of COVID-19 by limitation of daily flights as well as elapsed time minimization. As airports are among high risk places in COVID-19 pandemic, minimization of infection risk is considered in this model for the first time. Genetic algorithm is used as the solution approach, and its efficiency is compared to GAMS in small and medium-size problems.
Design/methodology/approach
One of the most complex issues in airlines is crew scheduling problem which is divided into two subproblems: crew pairing problem (CPP) and crew rostering problem (CRP). Generating crew pairings is a tremendous and exhausting task as millions of pairings may be generated for an airline. Moreover, crew cost has the largest share in total cost of airlines after fuel cost. As a result, crew scheduling with the aim of cost minimization is one of the most important issues in airlines. In this paper, a new bi-objective mixed integer programming model is proposed to generate pairings in such a way that deadhead cost, crew cost and the risk of COVID-19 are minimized.
Findings
The proposed model is applied for domestic flights of Iran Air airline. The results of the study indicate that genetic algorithm solutions have only 0.414 and 0.380 gap on average to optimum values of the first and the second objective functions, respectively. Due to the flexibility of the proposed model, it improves solutions resulted from existing models with fixed-duty pairings. Crew cost is decreased by 12.82, 24.72, 4.05 and 14.86% compared to one-duty to four-duty models. In detail, crew salary is improved by 12.85, 24.64, 4.07 and 14.91% and deadhead cost is decreased by 11.87, 26.98, 3.27, and 13.35% compared to one-duty to four-duty models, respectively.
Originality/value
The authors confirm that it is an original paper, has not been published elsewhere and is not currently under consideration of any other journal.

Abstract
Purpose
The purpose of this study is to examine the situation of lesbians, gays, bisexuals, transgender, queer and asexual (LGBTQA+) youth in Spain, pre-examining the links between the people they live with, their support networks and their perception of being a burden.
Design/methodology/approach
This study traces some brushstrokes through the preliminary results of the LGBTQA+ population between 13 and 21 years old (n = 445). These data are part of a larger project with 2,800+ respondents.
Findings
This study’s data highlight the connections between places of cohabitation, support and vulnerability in a crisis situation. In general, gender identity, age, support and feelings of acceptance have been key variables in identifying psychosocial factors related to the health of this population. Lastly, the authors offer some future guidelines to improve the situation of young people in the face of new situations of confinement, incorporating good practices for children and youth services.
Research limitations/implications
The use of the snowball technique for data collection may limit the representativeness of the sample. In the same way that data collection is used through access to an online questionnaire, it can limit access to certain people.
Practical implications
Address the psychosocial needs of LGBTQA+ youth, especially in crisis situations. With our data, we can improve services for future situations of confinement due to coronavirus, planning actions that include the youngest members of this population group, as well as those with non-normative sexualities and identities.
Social implications
Encourage and diversify support for LGBTQA+ youth from their families, peers, teachers and other professionals working in the youth field. This support would be congruent with the anti-discriminatory and trans-specific legislation existing in most Spanish regions. Furthermore, it would propose a social change that not only benefits LGTBQA+ people, as it allows for a more inclusive cultural change for all in terms of gender and sexuality.
Originality/value
New data obtained within the time frame of the state of alarm are provided, concerning a social group that has been little researched and that finds itself in an unprecedented health crisis.

Abstract
Purpose
At the European level, on January 1st 2018, the accounting standard IFRS 9, on the principles for the accounting information of financial instruments entered into force. The objective of this research paper is to analyse the impact of the first application of IFRS 9 on the credit institutions listed in Spain, specifically, its effects on their financial statements and the corresponding audit reports.
Design/methodology/approach
In order to achieve research purpose, a descriptive analysis of the analysed entities has been carried out, through the financial and economic indicators, and through the review of the corresponding audit reports.
Findings
The results show that the application of IFRS 9 had a significant effect (both positive and negative) on the results of the subject companies. Based on the audit reports, the application of this new standard increased the degree of complexity and that of accounting estimates in the financial statements.
Originality/value
This research is an important contribution to the literature on this topic because it analyses the impact of IFRS 9 under the main points of view that allow for a more complete understanding of the standard thus addressing the regulatory accounting standpoint, the economic–financial impact and the consequences on the implementation process.

Abstract
Purpose
The use of linear models has major limitations for accurately representing the true link between gender diversity and organizational performance. This study aims to explore two curvilinear models and tests which one – the U-shape or the inverted U-shape – best represents the gender diversity–performance link at two hierarchical levels: the board of directors and the workforce.
Design/methodology/approach
Both models are tested using data collected from a representative sample of Spanish educational organizations, which are dominated numerically by women, although women are still slightly underrepresented in managerial positions.
Findings
The results show the existence of an inverted U-shape and, therefore, the existence of a potential “optimal” level of gender diversity for both the board of directors and the workforce. While the highest performance by the board of directors is attained when the proportion of women and men is balanced in the workforce, the highest level of performance is attained when the proportion of women is greater.
Originality/value
There are hardly any studies simultaneously exploring the gender diversity–performance linkage at two hierarchical levels where the proportion of women/men is substantially different: the board of directors and the workforce. Thus, this study contributes to better know whether such relationship is dependent on the hierarchical position. It is important to know this because each level is related to different functions and tasks and shape a social status that can significantly influence performance.
