Purpose Overall equipment effectiveness (OEE) is a metric for estimating equipment effectiveness of the industrial systems. The purpose of this paper is to identify maintenance improvement potentials using an OEE assessment within the croissant production line. Design/methodology/approach The present work is carried out by analyzing the failure and repair data of the line. The failure data cover a period of 15 months. During this period the croissant production line usually operates over the entire day (24 h per day) in three 8-h shifts per day, and pauses at the weekends. Descriptive statistics of the failure and repair data for the line based on scheduled and unscheduled interruptions were carried. Moreover, the actual availability (A), performance efficiency (PE) and quality rate (Q) measures, together with the complete OEE for each working day for the croissant production line, were shown. Findings The main objectives are to understand the operation management of the croissant production line, and to measure the OEE characteristics in precise quantitative terms. OEE analysis can help the company to identify the primary problems concerning the A, PE and Q and acts immediately. Originality/value This paper presents a successful evaluation of OEE which will provide a useful guide to aspects of the production process, which identifies the critical points of the line that require further improvement through effective maintenance strategy (i.e. total productive maintenance). Moreover, the analysis provides a useful perspective and helps managers and engineers make better decisions on how to improve manufacturing productivity and quality.

Purpose – Activities such as making personal phone calls, surfing on the internet, booking personal appointments or chatting with colleagues may or may not deviate attentions from work. With this in mind, the purpose of this paper is to examine gender differences and motivations behind personal activities employees do at work, as well as individuals’ perception of the time they spend doing these activities. Design/methodology/approach – Data were obtained from 35 individuals (M age=37.06 years; SD=7.80) from a Portuguese information technology company through an ethnographic method including a five-day non-participant direct observation (n=175 observations) and a questionnaire with open-ended questions. Findings – Results revealed that during a five-working-day period of eight hours per day, individuals spent around 58 minutes doing personal activities. During this time, individuals engaged mainly in socializing through conversation, internet use, smoking and taking coffee breaks. Results revealed that employees did not perceive the time they spent on non-work realted activities accurately, as the values of these perceptions were lower than the actual time. Moreover, through HLM, the findings showed that the time spent on conversation and internet use was moderated by the relationship between gender and the leisure vs home-related motivations associated with each personal activity developed at work. Originality/value – This study contributes to the literature on human resource management because it reveals how employees often perceive the time they spend on non-work related activities performed at work inaccurately. This study highlights the importance of including individual motivations when studying gender differences and personal activities performed at work. The current research discusses implications for practitioners and outlines suggestions for future studies.

Purpose This study aims to measure the impact of the Non-Cooperative Countries and Territories, Organization for Economic Cooperation and Development and US PATRIOT Act Section 311 blacklists on external deposits from blacklisted jurisdictions into BIS reporting countries in 1996–2008, a period when anti-money laundering-related actions were consistently less stringent than post-2010, to see whether they had an effect even absent the threat of sizable financial fines. Design/methodology/approach The study uses descriptive statistics and bivariate and multivariate regressions to analyze the probable impact from blacklists on non-bank external deposits. The country sample is divided into offshore financial centers (OFCs) and non-OFCs and includes 158 non-listed countries. The impact of the blacklists is tested both jointly and individually for the respective blacklists. Findings The authors find mixed impact from jurisdictions being blacklisted on the growth rate of stocks of deposits into BIS reporting countries. Effects are often zero, negative in several cases and positive in some cases. This is consistent with the “stigma effect” and the “stigma paradox” in the literature. An overall impact from blacklisting is difficult to discern. Different blacklists had different effects, and the same blacklist impacted countries differently, illustrating the importance of disaggregating the analysis by individual countries. Research limitations/implications Interpretation of these data is limited by the absence of comparable data on non-resident deposits in blacklisted jurisdictions. Practical implications The impact of a blacklist depends in part on the structure of the listed jurisdictions’ economies, implying that country-specific sanctions may be more effective than blacklists. Originality/value This is one of the very few papers to date to rigorously test the impact of blacklists on external deposits.

Purpose This study aims to investigate the characteristics, as well as the purpose and posts of the COVID-19 Facebook groups. Design/methodology/approach A systematic search for COVID-19 Facebook groups was conducted on June 1, 2020. Characteristics of the groups were examined using descriptive statistics. Mann-Whitney test was used to study the differences between groups. The study of the most popular groups’ posts was also carried out using the content analysis method. Findings The groups had a combined membership of 2,729,061 users. A total of 147,885 posts were received. There were about approximately 60% public groups. A high percentage of the groups (86.5%) had descriptions. The results showed a significant relationship between the groups’ description status and the number of members (p-value = 0.016). The majority of COVID-19 Facebook groups (56%) were created to meet their members’ information needs. The highest number of studied posts were related to vaccination (35.2%), followed by curfew rules (19.6%) and symptoms (10.6%). Originality/value Translating these insights into policies and practices will put policymakers and health-care providers in a stronger position to make better use of Facebook groups to support and enhance public knowledge about COVID-19.

Purpose Going further on a broad understanding of nonwork besides family, this study aims to analyze differences between women and men considering work-nonwork conflict (WNWC) in the Brazilian context, investigating time spent in eight nonwork dimensions and the dimensions more affected. Design/methodology/approach The study was quantitative and descriptive. A survey was conducted, based on a validated WNWC scale. The sample consisted of 338 professionals working in Brazil. Data analysis was conducted through descriptive statistics and analysis of variance. Findings Compared to men, women declare higher levels of WNWC considering the eight nonwork dimensions, present greater differences in stress-based conflicts and in more collective dimensions and have marriage or no children associated with more WNWC. Research limitations/implications The study highlights the need to include more nonwork aspects into career and management studies to influence organizational practices and individual choices. The main limitation is the non-probabilistic sample (results not generalizable). Practical implications Know more about WNWC will help organizations to improve lives by creating practices and a cultural environment to preserve women’s and men’s nonwork times. It may also help people to choose places to work for, matching their nonwork needs. Social implications The study reinforces demands from new family arrangements, more couples in dual-career and an aging society: organizations must prepare to have workers that want or need to dedicate time to other interests besides family or children. Originality/value It goes further on a broad understanding of nonwork besides family to understand WNWC and how it may affect differently men and women.

Purpose The purpose of this study is to investigate the determinants of breakaway success in road cycling races. Design/methodology/approach Descriptive statistics were computed, and a logit model of breakaway success was estimated based on a new kind of statistical data describing the development of each of the 268 breakaways that occurred in the 76 regular stages of the Tour de France 2013 to 2016. Findings Breakaway success partly depends on the physics of cycling: breakaways are more successful when the stage is hilly or in mountain than flat. In addition, the likelihood of breakaway success depends on strategic moves such as attack timing and the percentage of riders with a teammate in the breakaway. Research limitations/implications Understanding why certain breakaways succeed and others do not is useful to comprehend cycling performance and to help coopetitive temporary organizational forms such as breakaways optimize their strategic behavior. A limitation is the focus on the Tour de France only. Originality/value The present study adds to the literature on temporary organizational forms, coopetition and cycling performance by analyzing within-stage data in cycling and, as such, enabling to capture its strategic dimension.

Purpose – This paper aims to investigate the effectiveness of Baitul Maal wat Tamwil (BMT) in reducing poverty. Design/methodology/approach – The case study approach on BMT MMU Sidogiri (located at East Java Province) is taken. Two important and dominating products of BMT MMU Sidogiri (i.e. ba’i bithaman ‘ajil (BBA) and mudarabah) are examined carefully on how much they have helped the customers in reducing their poverty. The paper goes beyond data measurement using descriptive statistics, paired t-test and some poverty measurement indexes such as headcount index; poverty gap; Sen index; and Foster, Greer and Thorbecke Index to investigate the effectiveness of the BMT in reducing poverty. Findings – This paper reveals that BMT financing is effective in reducing poverty. Most of respondents can increase their income after receiving BMT financing. Products of BMT, especially BBA and mudarabah, to empower the poor in various productive businesses have been able to reduce the extent and severity of poverty. This paper also discloses some interesting and important findings related with how BMT’s work, so that it can contribute more to the knowledge enrichment, as well as the development of BMTs, in general, in realising their mission. Originality/value – The establishment of the so-called BMT in the form of an Islamic microfinance is intended initially to effectively help the poor. At present, there are around 3,874 BMTs operating around the country. Although the BMTs have been existing since more than ten years, no research has been conducted to examine their effectiveness in alleviating the poverty. This study in aimed at fulfilling this important gap.

PurposeThe purpose of this paper is to study if and how the evaluation of the boards in the top Nordic male football clubs affects the boards’ composition and work.Design/methodology/approachThe study includes all the clubs in the two top divisions in each of the five Nordic countries (Denmark, Finland, Iceland, Norway and Sweden). The study makes use of a questionnaire where 66 (out of 145) chairmen answer 17 questions concerning the board composition and work on a five‐point Likert‐scale.FindingsThe responses were related to whether the board is annually evaluated or not. Descriptive statistics demonstrates that more than half of the clubs have an annual board evaluation. Most common is that the Chairman performs the evaluation himself/herself with help from designated board members; the evaluation being performed through informal discussions. A total of 44 clubs have a nominee committee. Almost all of the clubs transfer the result of the board evaluation to its nominee committee, most commonly verbally. Furthermore, results show that board evaluation has a significant positive effect on the following functions of football boards: review of business plan, strategy, objective and budget; discussion on short‐term development; discussion on long‐term development; and work efficiency.Originality/valueThe results of this study are consistent with a similar study of listed Nordic companies. The main difference between the results of the two studies is that clubs, unlike publicly listed companies, almost always perform the evaluation through internal interviews rarely using external consultants and individual anonymous questionnaires.

Purpose The purpose of this paper is to compute reliability, availability and maintainability (RAM) indices to measure and improve the performance of an automated croissant production line under real working conditions. Based on this study, the authors demonstrate how RAM analysis is very useful for deciding maintenance intervals and for planning and organizing the adequate maintenance strategy. Design/methodology/approach The present work is carried out by analyzing failure and repair data based on statistical techniques. Descriptive statistics of the failure and repair data at workstation and line level were carried out. Trend and serial correlation tests validated the assumption of independence and identical distribution of the failure data were conducted. Moreover, the reliability and maintainability of both the croissant production line and its workstations have been estimated at different mission times with their best fit distribution. Findings The main objectives of the applied method are to understand the nature of the failure patterns, and to estimate the reliability and maintainability characteristics of the croissant production system in precise quantitative terms. The analysis identifies the critical points of the production line that require further improvement through effective maintenance strategy. Originality/value This study is anticipated to serve as an illuminating effort in conducting a complete RAM analysis and its effect on the performance of the system that works under real conditions. The advantage of the methodology is the continuous monitoring of the production process through appropriate indices, the utilization of which leads to a continuous cycle of improvement.
