Abstract
Purpose
Professional networks are conduits for career insight, vehicles for career exploration and incubators of professional identity. Accordingly, LinkedIn is a rich environment for university students' careers and employability learning. In this article, the authors review how the pedagogical use of LinkedIn has been conceived, implemented and evaluated in higher education research.
Design/methodology/approach
The authors conducted a scoping literature review on research articles and chapters investigating the use of LinkedIn for careers and employability learning. The authors conducted a systematic database search and screened the results, resulting in 30 eligible studies. Each study was analysed for research characteristics, theoretical foundations, reported affordances or outcomes and critical concerns.
Findings
The authors find little evidence of cohesion or consistency in the existing research. Studies draw on different theoretical and methodological approaches and use different measures of networking behaviours and competencies. Studies tend not to consider ethical concerns about using LinkedIn as a pedagogical tool.
Practical implications
The authors argue this is not yet a body of research that supports the synthesis necessary for a reliable evidence base. The authors recommend that educators employing LinkedIn in the curriculum ground their work in more coherent, cohesive and integrated theories of careers and employability learning.
Originality/value
This review summarises a body of literature on the use of LinkedIn as a pedagogical tool for careers and employability learning in higher education. This review describes and critiques the beginnings of an evidence-base from which educators can further investigate how students can be supported to develop their online professional networking skills.

Abstract
Purpose
This article aims to analyse how a teacher leads whole-class discussions during and after participating in lesson studies and to what extent that participation influences her teaching practice.
Design/methodology/approach
This is a qualitative/interpretative research with a case study design, carried out with a secondary school mathematics teacher who participated in two lesson studies. Data were collected from participant observation, audio recording of lesson study (LS) sessions and discussions with the teacher, video recording of lessons and semi-structured interviews. Frameworks regarding the teachers' actions are used in the analysis.
Findings
The results suggest that in her teaching practice, the teacher led students to explain their strategies with supporting/guiding actions, but she also challenged the students to justify their productions, ensuring that the students' ideas were clear. Additionally, the teacher explored incorrect strategies and disagreements, inviting and challenging other students to intervene or react and involved students in drawing connections, as discussed in the LS. Therefore, the teacher put into practice several actions teachers can do in leading whole-class discussions to promote students' learning. Participating in LS was an opportunity to rethink her teaching practice, as the teacher pointed out, bringing her a new perspective on leading discussions in which students play an active role in learning mathematics, creating opportunities for the students to explain and react to their colleagues' ideas.
Originality/value
This article examines an under-researched issue: the influence of LS on the way a teacher leads whole-class discussions, during and after participating in lesson studies.

Abstract
Purpose
Drawing on socio-cognitively orientated leadership studies, this paper aims to contribute to our understanding of host country employees’ (HCEs) negative perceptions of successive expatriate leadership by exploring how their memories of shared past experiences affect these perceptions. Contrary to previous work which tends to focus on HCEs’ attitudes towards individual expatriates, the authors shift attention to successive executive expatriate assignments within a single subsidiary.
Design/methodology/approach
The paper is based on an intrinsic case study carried out in a Polish subsidiary of an American multinational pharmaceutical company which had been managed by four successive expatriate General Managers and one local executive. The authors draw on interview data with 40 HCEs. Twenty-one semi-structured interviews were conducted with staff who had been managed by at least three of the subsidiary’s expatriate leaders.
Findings
The authors demonstrate how transference triggered by past experiences with expatriate leaders as well as HCEs’ implicit leadership theories affect HCEs’ negative perceptions of expatriate leadership and lead to the emergence of expatriate leadership schema.
Originality/value
To the best of the authors’ knowledge, this is the first study that explores the role of transference and implicit leadership theories in HCEs’ perceptions of successive executive expatriate assignments. By focussing on retrospective accounts of HCEs who had been managed by a series of successive expatriate leaders, our study has generated a more nuanced and contextualised understanding of the role of HCEs’ shared past experiences in shaping their perceptions of expatriate leadership. The authors propose a new concept – expatriate leadership schema – which describes HCEs’ cognitive structures, developed during past experiences with successive expatriate leaders, which specify what HCEs believe expatriate leadership to look like and what they expect from it.

Abstract
President Bill Clinton has had many opponents and enemies, most of whom come from the political right wing. Clinton supporters contend that these opponents, throughout the Clinton presidency, systematically have sought to undermine this president with the goal of bringing down his presidency and running him out of office; and that they have sought non‐electoral means to remove him from office, including Travelgate, the death of Deputy White House Counsel Vincent Foster, the Filegate controversy, and the Monica Lewinsky matter. This bibliography identifies these and other means by presenting citations about these individuals and organizations that have opposed Clinton. The bibliography is divided into five sections: General; “The conspiracy stream of conspiracy commerce”, a White House‐produced “report” presenting its view of a right‐wing conspiracy against the Clinton presidency; Funding; Conservative organizations; and Publishing/media. Many of the annotations note the links among these key players.

Abstract
Purpose
The level of R&D spending of a country tends to increase the national patent rate and, in consequence, can collaborate with its economic development. However, there are a few empirical studies investigating this phenomenon by comparing countries from all over the globe. The purpose of this paper is to disassemble the sources of R&D spending and identify the role of national patent applications as a mediator in the relationship between R&D spending and national development.
Design/methodology/approach
Panel data on patent applications in 35 countries of all continents (except Africa) over 15 years (from 1999 to 2013) regarding four levels of national R&D intensity (i.e. by enterprises, governments, higher education institutions and private non-profit organisations), gross domestic product (GDP) per capita, gross national income (GNI) and human development index (HDI) were collected from the OCDE. Then, two-stage panel regressions were conducted to test the hypotheses.
Findings
The empirical findings indicated that R&D spending from firms and higher education institutions (public and private) help to directly improve national patent applications, thus contributing to the national development (measured by GDP per capita, GNI per capita and HDI).
Originality/value
The importance of this study was to show that the investments in R&D made by universities and firms are more effective in leading to patent applications, which contributes to promoting national development. With these findings, governments can focus their efforts on stimulating these types of investments if they want to foster the growth of national patent rates.

Abstract
Purpose
Housing prices in Brazil have displayed an impressive growth in recent years, raising some concerns about the existence of a bubble in housing markets. In this paper, the authors implement an empirical methodology to identify whether or not there is a bubble in housing markets in Brazil.
Design/methodology/approach
Based on a theoretical model that establish that, in the absence of a bubble, a long-run equilibrium relationship should be observed between the market price of an asset and its dividends. The authors implement two methodologies. First, the authors assess whether there is a cointegration relationship between housing prices and housing rental prices. Second, the authors test whether the price-to-rent ratio is stationary.
Findings
The authors’ results show that there is evidence of a bubble in housing prices in Brazil. However, given the short span of the data, the authors perform a Monte Carlo simulation and show that the cointegration tests may be biased in small samples. Therefore, the authors should be caution when assessing the results.
Research limitations/implications
The results obtained from the cointegration analysis can be biased for small samples.
Practical implications
The information on the excessive increase of the prices of the properties in relation to their fundamental value can help in the decision-making on investment of the economic agents.
Social implications
These results corroborate the hypothesis that Brazil has an excessive appreciation in housing prices, and, as Silva and Besarria (2018) have suggested, this behavior explains, in part, the fact that the central bank has taken this issue into account when deciding about the stance of monetary policy of Brazil.
Originality/value
The originality is linked to the use of the Gregory-Hansen method of cointegration in the identification of bubbles and discussion of the limitations of the research through Monte Carlo simulation.

Abstract
Purpose
By fusing knowledge-based theory, organizational learning theory and dynamics capability theory, this study aims to explore, on the one hand, the linkage between exploration, sensing and tacit knowledge, and on the other hand, exploitation, seizing and explicit knowledge. Thereby, it argues that not only tacit knowledge but also explicit knowledge contributes to competitive advantage for firms. This study also investigates how knowledge transforms into profitability.
Design/methodology/approach
The conceptual model is tested with a study sample of 153 industrial organizations using structural equation modelling.
Findings
Results confirm the importance of both tacit and explicit knowledge for achieving sustainable competitive advantages. Furthermore, both tacit and explicit knowledge transform into profitability, both directly and through product innovation and customer centricity which play partial mediating roles.
Practical implications
Explicit knowledge strategies can be easier to manage, implement and institutionalize than tacit knowledge strategies, which require human component and intervention to succeed. Managers should hence first implement explicit knowledge strategies to gain expeditious results. Further, with the advent of digital technologies and algorithms that can extract deep customer insights and organizational experiences which are highly tacit in nature and codifying the same into explicit knowledge, the importance of explicit knowledge is further enlarged.
Originality/value
By fusing three adjacent theories to establish a robust model specification, this study is able to demonstrate the contribution of explicit knowledge in the firm’s competitive advantages.

Abstract
In September 1990, the U.S. Department of Education's Library Technology and Cooperation Grants Program awarded a three‐year grant to the Florida Center for Library Automation (FCLA), an agency of the Florida State University System, to develop software adhering to the ANSI Z39.50 Information Retrieval protocol standard. The Z39.50 software was to operate over the Open Systems Interconnect (OSI) communications protocols and be integrated with FCLA's NOTIS system, which is shared by all nine state universities in Florida. In order to test the correctness of its Z39.50 software, FCLA sought out other library software developers who would be willing to develop Z39.50 systems of their own. As part of this process, FCLA helped to found the Z39.50 Implementors' Group (ZIG), which has since gone on to improve the standard and promote Z39.50 implementations throughout much of the North American library systems marketplace. Early on in the project, it became apparent that TCP/IP would be a more heavily used communications vehicle for Z39.50 messages than OSI. FCLA expanded its design to include TCP/IP and, by the end of the grant in September 1993, will have a working Z39.50 system that can communicate over both OSI and TCP/IP networks.

Abstract
Purpose
Although credit unions are nonprofit organizations, their objectives depend on the efficient management of their resources and credit risk aligned with the principles of the cooperative doctrine. This paper aims to propose the combined use of credit scoring and profit scoring to increase the effectiveness of the loan-granting process in credit unions.
Design/methodology/approach
This sample is composed by the data of personal loans transactions of a Brazilian credit union.
Findings
The analysis reveals that the use of statistical methods improves significantly the predictability of default when compared to the use of subjective techniques and the superiority of the random forests model in estimating credit scoring and profit scoring when compared to logit and ordinary least squares method (OLS) regression. The study also illustrates how both analyses can be used jointly for more effective decision-making.
Originality/value
Replacing subjective analysis with objective credit analysis using deterministic models will benefit Brazilian credit unions. The credit decision will be based on the input variables and on clear criteria, turning the decision-making process impartial. The joint use of credit scoring and profit scoring allows granting credit for the clients with the highest potential to pay debt obligation and, at the same time, to certify that the transaction profitability meets the goals of the organization: to be sustainable and to provide loans and investment opportunities at attractive rates to members.
