Abstract
Purpose
Asset pricing literature is facing a credibility crisis, given debates associated with publication biases, data mining, replicability, crowding and lack of theoretic foundations. This study proposes that emerging markets (EMs), with their specific socioeconomic characteristics and lesser financial integration with developed markets (DMs), might provide useful arguments to the debate and improve our understanding of asset pricing. Beyond out-of-sample evidence for DM findings, EM research can unveil regional-specific factors overlooked by mainstream literature and investigating reasons behind differences can reveal epistemological elements for proposing and testing theories, and clarifying causal mechanisms.
Design/methodology/approach
The present work conducts an EM-focused systematic review, by applying the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, a transparent and replicable procedure, to gather a representative collection of papers and using bibliometric methods to analyze bibliographic data.
Findings
Besides summarizing and contextualizing scientific production, revealing most important themes and actors, we confirm a clear bias toward DM and identify low scientific collaboration among EM. Additionally, we assess to which extent current studies fulfills EM research potential.
Originality/value
There is a home bias in literature, with most studies focusing on DM. This systematic review is exclusive to EM literature and suggests how EM research can improve literature credibility.

Abstract
Purpose
The purpose of this paper is to identify the main factors of the dyadic alignment in the supply chain of capital goods companies.
Design/methodology/approach
A survey was conducted among 159 respondents (53 supplier companies, 53 manufacturers and 53 clients).
Findings
Using structural equation modelling, no evidence of alignment between suppliers and manufacturers was identified. However, for the manufacturers, there is a partial mediation effect of the operational capabilities in the relationship between supply chain management and business performance.
Originality/value
This research investigates whether there is a dyadic alignment among supplier–manufacturer, manufacturer–customer and supplier–customer from the capital goods manufacturers’ perspective.

Abstract
Purpose
Doctoral programs are primarily intended to train new professors and researchers to take positions requiring research competency. This paper aims to observe the scientific production of 734 Brazilian new PhDs in management and the possible link between the scientific output of the graduates and doctoral program rank.
Design/methodology/approach
Methodologically, the authors built a database collecting the journal publications of the first six years after doctoral degree of all PhDs in management graduated by Brazilian doctoral programs during the period of 1998-2008. The authors use cluster and descriptive analysis to explore PhD publication.
Findings
Results show a great disparity of productivity, where 10 per cent of all new PhDs account for most of the Brazilian research productivity, while most of the PhDs have a very low performance – and that the CAPES (the Brazilian institutional system) qualification of doctoral programs is not a good predictor of the performance of the future graduates. Results are discussed to understand this productivity gap among researchers in a context of a developing country where support institutions are working to improve quantity and quality of publication.
Practical implications
The results are useful for recruiters that need to decide between hiring new PhDs with low productivity graduated from high-ranked programs or new PhDs with high productivity from programs with more modest ranking. At least in part, the authors’ results question the real impact that the doctoral program’s prestige has on the performance of its graduates.
Social implications
There are implications for the future candidates to a management PhD program, for the Directors of these programs and for the institutional agencies that regulate and promote science and that establish the prevailing rules and norms that researchers and institutions follow.
Originality/value
The results are adamant in pointing out that there is a small group of highly productive new PhDs – that the authors called “stars”. Generally speaking, they may find these “star” new PhDs in several doctoral programs. They have also found that some of the new PhDs have a relatively higher level of international papers published, but not necessarily a larger volume of publications. Meanwhile, most PhDs present a very low level of performance. This has important contributions to the way they perceive the doctoral education in management, especially in Ibero-America, revealing insights about the quality of PhDs and PhD courses.

Abstract
Purpose
The purpose of this paper is to identify Brazilian and Chinese cultural, managerial and negotiation factors that can influence the beef trade between the two countries.
Design/methodology/approach
First, a matrix based on reliable secondary sources was established created upon indicators of economic, financial, policy, administrative, cultural, demographic, knowledge, global connectedness and geographic distance between the two countries. This was combined with primary data from interviews conducted with two key stakeholders of the supply chain, namely, the Brazilian agricultural attaché to China, and the director of Apex-Brasil. The results were analysed in a qualitative descriptive manner.
Findings
Cultural and political distances between Brazil and China are the most profound origins of challenges in negotiations on both the private and public level.
Research limitations/implications
The interviews were limited in number and to the Brazilian portion of agents involved in the beef trade (diplomats and APEX representative). The low number of interviews might be a limiting factor of the investigation. However, the interviewees’ key position in the supply chain and data triangulation with secondary sources equilibrates the results’ trustworthiness.
Social implications
China and Brazil are becoming important players in the international market. Brazil has become a leader in the production and export of agricultural commodities. Brazil is the first producer or the second exporter of coffee, soybean, ethanol, poultry, sugar and beef. In 2009, China became Brazil’s top partner in trade (Xi, 2016). In 2015, Brazil exported $35.6bn to and imported $30.7bn from China. In the foreseeable future China will continue to be the most dynamic economy worldwide. This trade dynamic can be a source of opportunities for Chinese and Brazilian enterprises.
Originality/value
Information collected and conclusions drawn from the research are unique in scientific and management literature related to this specific topic, and can be of great value for stakeholders, traders and diplomats in the Sino-Brazilian trade.

Abstract
Purpose
The purpose of this paper is to describe an innovative compliance control architecture for hybrid multi‐legged robots. The approach was verified on the hybrid legged‐wheeled robot ASGUARD, which was inspired by quadruped animals. The adaptive compliance controller allows the system to cope with a variety of stairs, very rough terrain, and is also able to move with high velocity on flat ground without changing the control parameters.
Design/methodology/approach
The paper shows how this adaptivity results in a versatile controller for hybrid legged‐wheeled robots. For the locomotion control we use an adaptive model of motion pattern generators. The control approach takes into account the proprioceptive information of the torques, which are applied on the legs. The controller itself is embedded on a FPGA‐based, custom designed motor control board. An additional proprioceptive inclination feedback is used to make the same controller more robust in terms of stair‐climbing capabilities.
Findings
The robot is well suited for disaster mitigation as well as for urban search and rescue missions, where it is often necessary to place sensors or cameras into dangerous or inaccessible areas to get a better situation awareness for the rescue personnel, before they enter a possibly dangerous area. A rugged, waterproof and dust‐proof corpus and the ability to swim are additional features of the robot.
Originality/value
Contrary to existing approaches, a pre‐defined walking pattern for stair‐climbing was not used, but an adaptive approach based only on internal sensor information. In contrast to many other walking pattern based robots, the direct proprioceptive feedback was used in order to modify the internal control loop, thus adapting the compliance of each leg on‐line.

Abstract
Political economies evolve institutionally and technologically over time. This means that to understand evolutionary political economy one must understand the nature of the evolutionary process in its full complexity. From the time of Darwin and Spencer natural selection has been seen as the foundation of evolution. This view has remained even as views of how evolution operates more broadly have changed. An issue that some have viewed as an aspect of evolution that natural selection may not fully explain is that of emergence of higher order structures, with this aspect having been associated with the idea of emergence. In recent decades it has been argued that self-organization dynamics may explain such emergence, with this being argued to be constrained, if not overshadowed, by natural selection. Just as the balance between these aspects is debated within organic evolutionary theory, it also arises in the evolution of political economy, as between such examples of self-organizing emergence as the Mengerian analysis of the appearance of commodity money in primitive societies and the natural selection that operates in the competition between firms in markets.

Abstract
Purpose
The purpose of this research project was to determine how the three biggest search engines interpret keyword stuffing as a negative design element.
Design/methodology/approach
This research was based on triangulation between scholar reporting, search engine claims, SEO practitioners and empirical evidence on the interpretation of keyword stuffing. Five websites with varying keyword densities were designed and submitted to Google, Yahoo! and Bing. Two phases of the experiment were done and the response of the search engines was recorded.
Findings
Scholars have indicated different views in respect of spamdexing, characterised by different keyword density measurements in the body text of a webpage. During both phases, almost all the test webpages, including the one with a 97.3 per cent keyword density, were indexed.
Research limitations/implications
Only the three biggest search engines were considered, and monitoring was done for a set time only. The claims that high keyword densities will lead to blacklisting have been refuted.
Originality/value
Websites should be designed with high quality, well‐written content. Even though keyword stuffing is unlikely to lead to search engine penalties, it could deter human visitors and reduce website value.

Abstract
The author presents the author’s experiences of the body in hatha yoga practice using Maurice Merleau-Ponty's phenomenological concepts and perspective to understand the feelings about the body, thoughts, and emotions. The author interprets the corporeality and intersubjectivity of hatha yoga practice in light of the author’s theory. The author gives some examples of embodied perception from the author’s practice. The examples the author’s give are based on the author’s experience in yoga practice and self-observations that the author have done during the research project on experiencing hatha yoga practice and knowledge transfer.

Abstract
Purpose
An overview of the current use of handwritten text recognition (HTR) on archival manuscript material, as provided by the EU H2020 funded Transkribus platform. It explains HTR, demonstrates Transkribus, gives examples of use cases, highlights the affect HTR may have on scholarship, and evidences this turning point of the advanced use of digitised heritage content. The paper aims to discuss these issues.
Design/methodology/approach
This paper adopts a case study approach, using the development and delivery of the one openly available HTR platform for manuscript material.
Findings
Transkribus has demonstrated that HTR is now a useable technology that can be employed in conjunction with mass digitisation to generate accurate transcripts of archival material. Use cases are demonstrated, and a cooperative model is suggested as a way to ensure sustainability and scaling of the platform. However, funding and resourcing issues are identified.
Research limitations/implications
The paper presents results from projects: further user studies could be undertaken involving interviews, surveys, etc.
Practical implications
Only HTR provided via Transkribus is covered: however, this is the only publicly available platform for HTR on individual collections of historical documents at time of writing and it represents the current state-of-the-art in this field.
Social implications
The increased access to information contained within historical texts has the potential to be transformational for both institutions and individuals.
Originality/value
This is the first published overview of how HTR is used by a wide archival studies community, reporting and showcasing current application of handwriting technology in the cultural heritage sector.
