Purpose – The linear analysis presented for the charge pump phase locked loops (CPPLLs) becomes inaccurate or incorrect where cycle slipping occurs. In this paper, an analytical approach is proposed, which explains the conditions in which cycle slipping happens. Using the analytical results, one can simply design or redesign a CPPLL to prevent or decrease cycle slipping and hence decreasing the locking time. The paper aims to discuss these issues. Design/methodology/approach – To obtain cycle slipping conditions, CPPLL's signals in the time domain are tracked and cycle slipping condition is investigated. Based on the proposed analysis, by comparing a simple function of system's parameters with a threshold, cycle slipping is predicted. Findings – The cycle slipping conditions are expressed in terms of system's parameters and the size of the input frequency step. The method is also generalized for a fast CPPLL with an aid-lock BBFC circuit. The good accuracy of the analytical predictions is verified using simulations in Matlab/Simulink. Originality/value – A new analytical method for cycle slipping prediction in CPPLLs is presented. A closed form equation in terms of system's parameters and input frequency step has been presented, which can predict the cycle slipping possibility in the system without a need to perform the full time-consuming simulations. This analytical method that uses the LambertW function's properties proposes a threshold to predict cycle slipping in the system. This method not only can be used by designers to predict cycle slipping but can also be used to design the CPPLL in order to remove or decrease cycle slipping. The method is also generalized for fast locking charge pump PLLs and as a case study, cycle slipping prediction in the BBFC-CPPLL is performed.

Regulation Of Emotion

Theoretical basis The term emotional intelligence was coined by the researchers Peter Salavoy and John Mayer. The concept was popularized by Daniel Goleman through his book Emotional Intelligence published in 1996. According to Salavoy and Mayer (1990), emotional intelligence consists of a set of skills hypothesized to contribute to the accurate appraisal and expression of emotion in oneself and in others, the effective regulation of emotion in self and others and the use of feelings to motivate, plan and achieve in one’s life. Research methodology The case study uses two sources of information, namely, primary and secondary. Dr Dev, a senior training and development manager with a multinational company constituted the primary source. The secondary source consisted of information publicly available on various websites. The case has been disguised for various reasons. Case overview/synopsis Lady mosquito at NPS Mumbai is a case study on emotional intelligence, a much sought-after concept in management education, but not many case studies have been written on the topic. This case involves an interaction that took place between a facilitator and a learner, and it highlights the importance of emotional intelligence in day-to-day communication. The use of emotional intelligence will manifold improve the ability of the facilitator to understand the learners’ behavior in the classroom. This will further enhance the effectiveness of learning, as the motivated facilitator/trainer will be more committed to engaging the learners in their educational activities. Complexity academic level This case has been developed to be used in postgraduate and undergraduate management programs. This case can also be used in management development programs for executives. As the case provides a basic understanding of human behavior and thereby teaches to manage others just by managing oneself. As the case revolves around a facilitator and the learner, it can also be used in the trainer program for facilitators who desire to conduct training programs or want to take teaching as a full-time career.

Purpose – The aim of this paper is to analyse the experience of female part-time professionals with employee and managerial positions with the utilisation of flexible work arrangements in a corporate environment in the country with a full-time dominated work culture. The data represent a rare case study of the work environment in a Czech branch of one multinational company. This paper focusses on the position of female employees working part-time in professional and managerial positions. The reason for such an arrangement is their attempt to combine career and care for pre-school children. This paper evaluates the effects of flexible work policies in an environment where part-time work for female professionals is rarely available and, therefore, precious. In particular, this paper discusses conditions under which these arrangements are available and its impact on gender equality. Design/methodology/approach – The paper represents a rare case-study of an organisational environment. The seven analysed interviews derive from a larger study on the corporate environment which included 35 interviews and a series of participatory observations. In the analysis, the following questions are discussed: What is the position of employees working within flexible working arrangements in a specific corporate culture? Which aspects of flexible working arrangements affect the professional recognition and evaluation of the employees? To what extent and how do flexible working arrangements affect employee satisfaction with their working and private lives? Findings – The data reveal the diverse and often subtle forms of discrimination and exploitation of working mothers, who use the flexible working arrangement as a work-family reconciliation strategy. Female employees working with alternative working arrangements do not have equal bargaining power in comparison to other employees, regardless of whether they are professionals, and sometimes in managerial positions. At the formal level, the part-time professionals are restricted in pay and in access to the company benefits. In the informal relations within the workplace, their work lacks of sufficient recognition of colleagues and superiors. Overall, part-time work for female professionals and managers leads to an entrapment between the needs of their family and the expectations of their employer. Practical implications – The research reveals the practical limitation in introducing policies the work-life reconciliation policies. The results show the need to focus on promoting better conditions for employees working part-time. Also, it shows that managerial and highly demanding professional positions can be executed on a part-time basis if the work environment is open towards accepting this arrangement. Moreover, the findings outline the possibilities of developing workplace practices in the Czech Republic in a woman-friendly direction. Social implications – Specific legislative arrangements should be enacted, providing better protection for employees in non-standard employment. At the same time, the incentives for employers to enable part-time working arrangements should be provided. Originality/value – The amount of research on female professionals working part-time or from home is rather limited in context of the post-communist countries. The paper discusses the “double” tokenism of the women working in the leadership positions and at the same time in flexible working arrangements in the full-time working culture.

PurposeThis paper examines architecture as an example of the evolving context of qualifying routes in UK professions.Design/methodology/approachThe background and current state of architectural education, qualifying routes and regulatory frameworks in the UK is presented as a case-study, and compared with practices in professional education and qualifying more generally including the use of Degree Apprenticeships.FindingsArchitecture has since the 1960s maintained an entry-route that is premised on periods of full-time academic study plus full-time practice. While a minority part-time version of this route has always existed (and is now being expanded through Degree Apprenticeships), variations seen in other professions such as experienced practitioner entry and accelerated routes from cognate fields have so far been lacking. Pressures for reform are emerging both from external changes affecting the profession and from the high cost of qualifying in relation to median incomes in the sector.Practical implicationsThere is a need for more flexible and less expensive routes to qualifying as an architect, with substantial scope to use practices from other professions and areas of higher education to recognise existing levels of competence and improve crossover with other design and construction fields.Originality/valueThis is the first review of architectural qualifying requirements that has been made in the context of professional entry more generally.

Purpose – The purpose of this paper is to investigate a model for facilitating employees’ and full-time, non-business students’ entrepreneurial capabilities during their optional entrepreneurship studies at one Finnish Open University. Design/methodology/approach – The case study investigates the course in which transitions from employees or non-business students to nascent entrepreneurs are presupposed to happen. The examined phenomenon is the lecturer’s (the author’s) facilitating process. The key method is to support the ES students in developing their daily practices and reflecting on these from an entrepreneurial view. Findings – For the ES students identified as latent nascent entrepreneurs, the development period facilitated by exploiting small-sized entrepreneurs’ attributes, skills and behaviour mainly awakened intrapreneurship. Intrapreneurship was an unexpected phase because the lecturer did not offer it as an alternative. This necessitated the lecturer to investigate her instructions during the ES students’ development processes to find out the crucial factors that might have awakened their intrapreneurship. Practical implications – In the current case, intrapreneurship seems to be an essential phase between latent nascent and nascent entrepreneurship. Therefore, it is important to note the elements in the facilitation process that may strengthen intrapreneurship. The implications of latent nascent entrepreneurs’ entrepreneurial processes should be further investigated, whether strengthening intrapreneurship would produce more nascent entrepreneurs than processes without noticing intrapreneurship. Originality/value – Developing and reflecting on one’s practices from an entrepreneurial viewpoint as an employee or a full-time, non-business student seem worthy of more examinations. Generally, opportunities for encouraging new start-ups by these people comprise an unknown area when considering supported entrepreneurial processes.

Study Methodology

PurposeThe purpose of this study is to identify strengths and weaknesses in knowledge sharing between related post-bushfire investigative agencies. Based on this study, such a sharing of knowledge is essential to enhance collaboration amongst practitioners in the reduction and management of the risk of bushfires.Design/methodology/approachThe authors use a case study methodology; the research design is based on comparative analysis of six post-bushfire investigative departments in Italy and Australia (Victoria). A total of 44 bushfire investigators were interviewed between 2012 and 2013, across the two countries. Using focus groups and face-to-face interviews, the extent and quality of intra- and interagency knowledge sharing is analysed.FindingsDespite the desire to collaborate, there are three main conditions that prevent an effective interagency collaboration within the bushfire investigation network, namely, separation, unidirectionality and interpersonal disengagement. This study finds that knowledge sharing suffers from a missing “feedback system” culture, where agencies give each other feedback with strictly bureaucratic purposes, rather than create an ongoing learning mechanism that develops after every investigation. At agency level, we also find that, sharing investigative knowledge and experience through daily and planned meetings is a standard practice to police members; but this is not found in the fire agencies. When made cross-country comparisons between Australia and Italy, the existence of common courses, joint manuals and the sharing of human resources witnessed in Australia (Victoria) is something that would benefit Italian agencies still trapped in a competitive and jurisdictional mindset. At the same time, Australian agencies might want to reconsider the separation between bushfire suppression and investigation, a distinction that has been made clear in Italy through the creation of full-time bushfire investigator positions.Practical implicationsThis paper contributes to the improvement of interagency collaboration through the development of an investigative “social knowledge”. It reinforces the assumption that, to reduce and effectively manage the risk of bushfires, a combined effort from different stakeholders involved in forensic investigation is necessary.Originality/valueGiven the lack of research undertaken in the area of bushfire investigation, the current paper represents a unique piece of work. It is unusual, not only in identifying the current issues within the bushfire investigation network but also in providing agencies with theoretical and practical insights on how to reduce the extremely high number of bushfires and their risks.

Purpose Savant syndrome, a very rare condition in the world, refers to individuals who have extraordinary talents but might have disabilities that prevent them from maintaining their life. The purpose of this paper is to investigate the views of conservatory instructors about the education of Buğra Çankır (BC), a musical savant with autism. Design/methodology/approach As it was difficult to communicate with BC and elicit his views, interviews were conducted with his teachers, who had similar experiences in his music education process. The participants were six instructors who worked as full-time instructors in the conservatory. The participants were administered a semi-structured focus group interview form that described the difficulties, experiences, perceptions and feelings they had in their interactions with BC. Data obtained from the study were subjected to content analysis methods performed by the researchers; analysis involved identification of the codes and themes and formation of sub-themes and codes in line with these themes. Findings Results showed that the participants had difficulties in teaching BC because of having insufficient knowledge about his features. In addition, while planning the conservatory education processes, the participants were found to redesign the teaching content considering the features of the student. Research limitations/implications The present case study is important in terms of revealing the problems experienced in the education processes of these individuals. More detailed qualitative studies or action research could be utilised in studies to be conducted in the future. Originality/value BC’s educational experience is the first case for educational institutions and instructors in Turkey.

Purpose The purpose of this paper is to explore how students, full-time and part-time, may be supported in becoming ambidextrous – developing “intrapreneurial” skills and capabilities, as well as being introduced to more typical “entrepreneurial” activities. It is proposed that both perspectives will be necessary for future graduates. Design/methodology/approach The paper highlights the fast-changing nature of the economic and employment context and the future requirements for graduate skills. It analyses and evaluates a framework of curricular and extra-curricular activities which has been developed to address future skills needs. The paper uses a case study to illustrate the issue. Findings The paper concludes that with increasingly flexible career paths, there is a need for graduates to be prepared for portfolio careers in which they move between employment and self-employment. The development of an independent mindset which can identify and exploit innovation is therefore important. Practical implications The paper outlines an approach that has been implemented in a UK higher education institution to the development of innovation skills which is responsive to a wider range of students than the conventional cohort of young, full-time students. Originality/value The paper highlights the importance of designing educational experiences which directly address students’ situations and experiences. It also identifies the role of work-based research in the development of an innovative mindset.

And Function

Purpose The purpose of this paper is to advance the understanding of the importance and function of narratives in the context of organizational change. Design/methodology/approach Drawing on Schutz’s theory of human intentional action, the author introduces the concept of a mental plan – broadly referring to the mental rehearsal of a future act – and builds a conceptual framework that connects mental plans to narratives. Viewing actions through the lens of mental plans and narratives would prompt a combination of rigid clarity and flexible vagueness in both the action and the stories. Considering this, the author developed a longitudinal case study on organizational change in an international company amid an intense renewal process. Several narratives about the project of organizational change were studied, and these revealed some of the functions that narratives serve as well as their importance in connecting plans of human action with the actual execution of those actions. This paper identifies numerous distinct narratives, created by different actors, which focus on the process of setting and reaching a final goal. The content of these narratives reveals how different views and strategies co-exist simultaneously in the organization, even when actors are trying to achieve the same goal. Findings Traditionally, management takes an analytical approach to understand how change occurs in organizations. This paper emphasizes the importance and functions of narratives as a fundamental component of organizational change. On par with the linear plan of action, it is argued that the assortment of narratives delivered from various points of views in the organization are, indeed, the driver of change, and their dynamic interaction would determine the outcome of a change project. Originality/value The paper advances the understanding of the role of narratives in organizational change. This paper emphasizes the difficulties of using an analytical approach as a basis for understanding how action is implemented. This difficulty arises because of the variety of interpretations and meanings given to the project purpose and goal, and how these interpretations and meanings influence people’s future actions or project success.
