PurposeThis paper provides an important perspective to the predictive capacity of Fed and European Central Bank (ECB) meeting dates and production announcements for the dynamic conditional correlation (DCC) between Bitcoin and energy commodities returns and volatilities during the period from August 11, 2015 to March 31, 2018.Design/methodology/approachTo assess empirically the unanticipated component of the US and ECB monetary policy, the authors pursue the Kuttner's approach and use the federal funds futures and the ECB funds futures to assess the surprise component. The authors use the approach of DCC as introduced by Engle (2002) during the period from August 11, 2015 to March 31, 2018.FindingsThe authors’ results suggest strong significant DCCs between Bitcoin and energy commodity markets if monetary policy surprises are incorporated in variance. These results confirmed the financialization of Bitcoin and commodity energy markets. Finally, the DCC between Bitcoin and energy commodity markets appears to respond considerably more in the case of Fed surprises than ECB surprises.Originality/valueThis study is a crucial topic for policymakers and portfolio risk managers.

Purpose The purpose of this paper is to analyze Lenovo’s successful acquisition of IBM’s PC division using Ghemawat’s (2001) CAGE framework. It was an acquisition that was so full of symbols that it is difficult to know where to begin. Lenovo’s purchase of IBM in 2005 was first seen as a sign of the rapid growth and expansion of the Chinese economy and its transformation away from the traditional manufacturing base to more high-tech areas. For doomsday merchants in the land of Uncle Sam, it foretold the end of the world domination of the US economy. Despite a considerable number of skeptics at the time, Lenovo was clearly up to the task. Such was the success of the acquisition that by 2015, Lenovo could claim to have grown into the world’s number 1 PC maker, number 3 smartphone manufacturer and number 3 in the production of tablet computers. Design/methodology/approach This paper is a case study. Findings Despite a considerable number of skeptics at the time, Lenovo was clearly up to the task. Such was the success of the acquisition that by 2015, Lenovo could claim to have grown into the world’s number 1 PC maker, number 3 smartphone manufacturer and number 3 in the production of tablet computers. Indeed, by 2014, the firm had enough confidence to add the IBM server business to its portfolio. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Purpose To explain the US Securities and Exchange Commission’s (SEC’s) June 29, 2017 announcement (as updated August 17, 2017) that the staff of its Division of Corporation Finance will accept draft registration statement submissions from all companies for nonpublic review, thereby expanding a popular benefit previously available only to emerging growth companies (ECGs) under the JOBS Act and, in limited circumstances, to certain foreign private issuers under historical Staff practices. Design/methodology/approach Explains the rationale and limitations of the new policy, the existing confidential submission process, the expanded class of issuers and transactions that now qualifies for the nonpublic review process, and content and staff processing details. Findings Recognizing that the confidential submission process for EGCs proved highly popular and quickly became standard practice for eligible companies seeking to conduct an IPO, the SEC has made the nonpublic review process available to an expanded class of issuers and transactions. The expanded confidential submission process for IPOs addresses some of the typical concerns associated with engaging in the IPO process by giving a company more time and flexibility to determine whether it actually will be able to achieve the benefits of going public before it incurs the burdens and expenses of doing so.

PurposePrevious research suggests that many active females are not engaging in sports bra use, despite the positive health benefits. The aim of this study was to establish and compare sports bra use, preferences and bra fit issues for exercising females in some of the largest and most diverse global underwear markets (the US, the UK and China).Design/methodology/approachA survey covering activity levels, sports bra use and preferences, bra issues and demographics was administered via Qualtrics and completed by 3,147 physically active females (aged ≥ 18 years) from the US (n = 1,060), UK (n = 1,050) and China (n = 1,037).FindingsIn general, participants were 25–29 years, 121 to 140 pounds, 34B bra size and pre-menopausal. “I cannot find the right sports bra” was the most frequent breast barrier to exercise (25.4%). Three-quarters of women wore a sports bra during exercise, with significantly higher use in China (83.9%), compared to the UK (67.2%). A third of all participants reported sports bra shoulder straps “digging into the skin”. Sports bra preferences were: compression sports bras with a racer back, wide straps and thick straps in the US and the UK; thin straps in China and adjustable straps and underband, no wire and maximum breast coverage in the US and the UK, including nipple concealment and with padded/moulded cups.Originality/valueInformation provided on differences in sports bra use, preferences and bra issues across three major global markets could be utilised by brands and manufacturers to optimise bra marketing and fit education initiatives and inform future sports bra design and distribution strategies.

Purpose The purpose of this paper is to analyze the conduct of monetary policy in Brazil and estimate the country’s neutral real interest rate. Design/methodology/approach The authors make use of a state-space macroeconomic model representation. Findings The period of analysis goes from 2003 up to the end of 2013 and the results show that the country’s natural rate of interest was around 4.2 percent in December 2013. Originality/value One of the main differences of this work is the inclusion of variables such as the real exchange rate and world interest rate. This is important because these variables play an important role in the definition of the interest rate and, consequently, in the definition of the neutral interest rate.

Purpose The study of an energy company in the US was intended to explore how employees’ emotions after downsizing impacted their learning following the downsizing event. Design/methodology/approach The authors elected to study an energy company based in Oklahoma City that had experienced several downsizings over the previous 10 years. More recently, there had been a major restructuring on departments as a result of the downsizing. At the time of the study there were 400 employees. They carried out 30-60 minute semi-structured interviews with nine volunteers, all affected by layoffs. Five were impacted by the loss of a supervisor and all had faced the loss of a co-worker. Findings Three main themes emerged – firstly “resilience”, where they focused on getting back to work, secondly “loyalty”, where most participants spoke about their new-found appreciation for their job and willingness to help colleagues, and finally “moral support” in which they spoke about how the experience strengthened relationships with colleagues, and they came to rely on each other. Originality/value The authors said their study pointed the way forward for organizations that wanted to understand the emotional impact of downsizing, and its effect on learning. They suggested some practical methods to enhance empathy and rebuild relationships.

Insight Into

PurposeDrawing on the survey of Spanish-speaking immigrant and migrant readers in Canada and the US, this study pursues three goals: (1) examine the image of the library held by these readers and trace the change of this image after the international migration; (2) use the study findings to revise and update the currently existing typologies of the image of the library; and (3) understand ethical and effective research practices in the studies of immigrant/migrant communities whereby researchers are external to communities in question.Design/methodology/approachThe data about immigrant/migrant readers were collected through a self-administered survey questionnaire that was available both in print and electronically, both in Spanish and English. The data analysis was guided by hermeneutic phenomenology, as explicated in the article. Theoretical examination of the image of the library relied on the earlier typology developed by V. Stelmakh.FindingsThe study elucidates perceptions of libraries and librarians in both North America and countries of origin held by Spanish-speaking immigrant/migrant readers, and highlights changes that occur in the image of the library as readers move across geographic borders. Building on the empirical data, the article develops a new typology of the image of the library. It also offers insight into ethical and effective ways of engaging with immigrant communities that should be upheld by researchers from outside the communities in question.Originality/valueIt is the first known study that systematically traces the changes in the image of the library which occur alongside geographic and sociocultural migrations. It is also the first known study that focuses specifically on readers rather than library users in general. The new typology consists of four different elements – the cultural image; the functional image; the humanistic image; and the ideological image of the library – and is accompanied by detailed definitions of each.
