Abstract
Purpose
The purpose of this paper is to assess the quality of commercial lubricant oils. A spectroscopic method was used in combination with multivariate regression techniques (ordinary multivariate multiple regression, principal components analysis, partial least squares, and support vector regression (SVR)).
Design/methodology/approach
The rationale behind the use of SVR was the fuzzy characteristics of the signal and its inherent ability to find nonlinear, global solutions in highly complex dimensional input spaces. Thus, SVR allows extracting useful information from calibration samples that makes it possible to characterize physical-chemical properties of the lubricant oils.
Findings
A dataset of 42 spectra measured from oil standards was studied to assess the concentration of copper into the oils and, thus, evaluate the wearing of the machinery. It was found that the use of SVR was very advantageous to get a regression model.
Originality/value
The use of genetic algorithms coupled to SVR was considered in order to reduce the time needed to find the optimal parameters required to get a suitable prediction model.

Abstract
Much of the current literature on category construction and maintenance has focused primarily on the disciplining effect of audiences that evaluate for conformity. This literature often characterizes categories as benign organizing devices that bring order to social life. However, categories are also contentious political and cultural productions. This is especially so, when the categories are hybrid. Employing a qualitative case study of an impact investing organization operating in Sub-Saharan Africa, we illustrate how the construction and maintenance of hybrid categories can have potentially advantageous effects for certain actors by shaping the architecture of knowledge and transferring legitimacy to otherwise illegitimate actors or nascent practices. The findings of this study highlight how some hybrid categories can be used to create and maintain unequal relations of power.

This paper aims to identify the threshold concept in intellectual property (IP) law.
Abstract
Purpose
This paper aims to identify the threshold concept in intellectual property (IP) law.
Design/methodology/approach
It used doctrinal methods for such identification based on the existing pedagogical scholarship in the field of effective teaching and learning.
Findings
It explained how the use of the threshold concept in IP law education could facilitate understanding of IP law from globalised perspectives and validate use of IP in a balanced way.
Research limitations/implications
It is yet to be tested for practical curriculum design in different jurisdictions.
Practical implications
The understanding of threshold concepts in IP law could generate “eureka” moments, when, after a long struggle, students come to a deep understanding of a new concept.
Social implications
This will facilitate social acceptance of IP for balancing global obligation and national developmental and social goals.
Originality/value
Till date, little work has been undertaken on the threshold concepts on IP law. Therefore, this study tried to make a unique contribution by identifying threshold concepts in intellectual property law.

Abstract
Numerous commentators have suggested that Barack Obama represents a new “post-racial” politics in the United States, distinct from a pre-existing contentious form that originated with the civil rights era. Drawing on secondary historical data, Mr. Obama's presidential campaign speeches, and county-level electoral returns from Indiana and North Carolina, I argue in contrast to such claims that post-racial politics comprise the latest in a line of successive attempts by the Democratic Party to articulate the New Deal voting bloc, in which the white suburban middle class is the primary constituency while African Americans are of secondary importance. By addressing the question of “Obama and the Politics of Race” in this way, this chapter seeks to integrate political parties into the study of racial ideologies. Specifically, it suggests that the latter may originate and subsequently develop in the context of partisan struggle.

Abstract
When we inhabit time and space, how can foresight be other than a parallax view? Not only is the ground shifting beneath our feet, but our culture colours our perspective. We replace our imagination with computers and program them with data that is often skewed. We begrudge paying our taxes yet offload risk to the public sector. For the environment in particular, the stakes have never been higher. Faith in the future means we all jump together.

Abstract
The BLLD is able to satisfy a growing percentage of requests for material in the humanities. Its retrospective collections and current purchasing policy, which are described in some detail, enable it to supply half of the humanities monographs requested and two thirds of the serials from stock, with increasingly high success rates for more recent material. A further 30% of monograph requests and 15% of serial requests are satisfied from back‐up libraries (including the legal deposit libraries) and other sources.

Abstract
Purpose
This chapter is intended to present the onset, evolution, and decline of Compañía Minera El Zancudo, considered the largest Colombian company in the nineteenth century. Additionally, the chapter will examine its role in both the development of manufacturing industries and the introduction of modern capitalism in the country.
Methodology/approach
The case is based on secondary information collected according to a documentary research method in which the authors selected, categorized, interpreted, and confronted different sources concerning El Zancudo.
Findings
The inception and evolution of El Zancudo involved local and foreign knowledge, techniques, and capital investments that contributed to the company growing to the point of reaching the unprecedented figure of 1,350 workers in the year 1890. Its transition from a failed local mine to a prosperous and intricate business group is full of referrals and links to foreign investment, knowledge transfer, industrial development, and an orientation toward entrepreneurship that contributed to the understanding of subsequent enterprises not only in the Antioquia region but also across the entire country.
Research limitations/implications
This case study was written using limited reliable secondary sources about El Zancudo. Other significant Colombian companies in the nineteenth century (Ferrería de Pacho, Ferrería de Amagá, Empresa Textilera de Samacá, and Cervecería Bavaria) and their links to El Zancudo were mentioned but not deeply analyzed in this chapter.
Practical implications
The clear-cut causes that led El Zacudo to close its operations within the first decades of the twentieth century are worthy of discussion, not only by scholars and business practitioners, but also by policy makers in order to understand the phenomenon and possibly prevent existing companies from failing in a similar manner.
Originality/value
This case brings together the scattered literature on El Zancudo and analyzes the drivers and consequences of both its rise and fall, taking into consideration the specific historical, political, and economic contexts, furthermore, it establishes some linkages between this case and other companies under similar situations.

Abstract
SEPTEMBER finds the summer irrevocably over, although there will still be one or two very beautiful months in the English autumn remaining. It is usually the time when the older librarian thinks of conferences, and today he realizes regretfully that these have receded into what already seems a remote past. This month as we write we have to repeat the expectation we have expressed every month since May that before these words appear in print the threatened lightning attack on the life of England will have been made by the Nazis. It is becoming so customary, however, that one can only suggest that so far as circumstances allow we proceed with our normal work. The circumstances may make this difficult but they should be faced. One thing stands out: that in public libraries, at anyrate, the demands made by readers have gradually returned to their usual level and in some places have risen above it. This does not always mean that the figures are as high as they were, because in many of the great cities and towns a part of the population, including a very large number of the children, have been evacuated. In spite of the pressure on the population as a whole, it would seem that head for head more books are being read now than at any previous time.

Abstract
Purpose
This study identifies the factors that influence companies to obtain the B corporation certification. Drawing from institutional isomorphism, gender socialization theory, the ethics of care and social identity theory, the authors examine the impact of geographic locality, product market competitions and owners’ demographic characteristics on a firm’s decision to be a certified B Corporation.
Design/methodology/approach
Using two sets of data, a hand-collected sample of 743 small businesses receiving a B Corporation certification between 2007 and 2014 and a sample of 902 firms participating in a B Lab survey from 2011 to 2013, the authors examine factors that influence firms’ decision to obtain the B Corporation and their environment, social and governance (ESG) performance.
Findings
Firms in states that are democratic-leaning, have a lower hourly wage rate or have a greater religious population are more likely to be early adopters and leaders of the B Corporation movement than those in other states. On average, states with a higher unemployment rate and more democratic-leaning voters have more B Corporation certified firms in each year and over the years. Additionally, product market competition is positively associated with firms’ likelihood of obtaining B Corporation certification and their ESG scores.
Practical implications
This study brings new insights to the understanding of purpose-driven enterprises and factors that influence firms’ decision to go through the B Corporation verification and certification process.
Originality/value
This study establishes a theoretical foundation that becoming a B Corporation is a corporate social responsibility (CSR) action and shows that existing theories explaining the factors motivating companies to engage in CSR can also be applied to explain firms’ motivation to become B Corporations.
