The Price equation and the unity of social evolution theory
Authors: Lehtonen Jussi 
Published: March 2020

The Price equation has been entangled with social evolution theory from the start. It has been used to derive the most general versions of kin selection theory, and Price himself produced a multilevel equation that provides an alternative formulation of social evolution theory, dividing selection into components between and within groups. In this sense, the Price equation forms a basis for both kin and group selection, so often pitted against each other in the literature. Contextual analysis and the neighbour approach are prominent alternatives for analysing group selection. I discuss these four approaches to social evolution theory and their connections to the Price equation, focusing on their similarities and common mathematical structure. Despite different notations and modelling traditions, all four approaches are ultimately linked by a common set of mathematical components, revealing their underlying unity in a transparent way. The Price equation can similarly be used in the derivation of streamlined, weak selection social evolution modelling methods. These weak selection models are practical and powerful methods for constructing models in evolutionary and behavioural ecology; they can clarify the causal structure of models, and can be easily converted between the four social evolution approaches just like their regression counterparts.This article is part of the theme issue ‘Fifty years of the Price equation’.
Different perspectives on non-genetic inheritance illustrate the versatile utility of the Price equation in evolutionary biology
Authors: Helanterä Heikki , Uller Tobias 
Published: March 2020

The diversity of genetic and non-genetic processes that make offspring resemble their parents are increasingly well understood. In addition to genetic inheritance, parent–offspring similarity is affected by epigenetic, behavioural and cultural mechanisms that collectively can be referred to as non-genetic inheritance. Given the generality of the Price equation as a description of evolutionary change, is it not surprising that the Price equation has been adopted to model the evolutionary implications of non-genetic inheritance. In this paper, we briefly introduce the heredity perspectives on which those models rely, discuss the extent to which these perspectives make different assumptions and place different emphases on the roles of heredity and development in evolution, and the types of empirical research programmes they motivate. The existence of multiple perspectives and explanatory aims highlight, on the one hand, the versatility of the Price equation and, on the other hand, the importance of understanding how heredity and development can be conceptualized in evolutionary studies.This article is part of the theme issue ‘Fifty years of the Price equation’.

AbstractBiallelic variants in NPC1, a lysosomal gene coding for a transmembrane protein involved in cholesterol trafficking, may cause Niemann-Pick disease type C (NPC). A few cases of NPC1 mutation carriers have been reported with a Parkinson’s disease (PD) presentation. In addition, pathological studies demonstrated phosphorylated alpha-synuclein and Lewy pathology in brains of NPC patients. Therefore, we aimed to examine whether NPC1 genetic variants may be associated with PD. Full sequencing of NPC1 was performed in 2,657 PD patients and 3,647 controls from three cohorts, using targeted sequencing with molecular inversion probes. A total of 9 common variants and 126 rare variants were identified across the three cohorts. To examine association with PD, regression models adjusted for age, sex and origin were performed for common variants, and optimal sequence Kernel association test (SKAT-O) was performed for rare variants. After correction for multiple comparisons, common and rare NPC1 variants were not associated with PD. Our results do not support a link between heterozygous variants in NPC1 and PD.

Published: March 2020

AbstractAlthough host membrane is known to play critical roles in the internalization of leishmania parasites inside macrophages (Mϕ), any detailed mechanistic understanding is missing. We show here that KMP-11, a small immunogenic protein ofLeishmania Donovani(LD) facilitates the infection process by binding to Mϕ membrane through its N-terminal domain (1-19AA). This binding results in a membrane phase transition that occurs at a threshold protein/lipid ratio, which is linked to the change in membrane tension. KMP-11 induced phase transition is also associated with lipid raft disruption and T-cell deactivation. Finally, using a combination of tryptophan-scanning mutagenesis and synthesized peptides, we develop a mathematical exposition, which demonstrates that hydrophobic moment (μH) and the number of residues involved in a mirror sequence (N) at the interacting N-terminal are governing factors for the membrane phase transition, which facilitates infection process.

ABSTRACTThe Amazon rainforest is a biodiversity hotspot and large terrestrial carbon sink that is threatened by agricultural conversion. Rainforest-to-pasture conversion leads to the release of a potent greenhouse gas by converting soil from a methane sink into a source. The biotic methane cycle is driven by microorganisms; therefore, this study focused on active methane-cycling microorganisms and their functions across land-use types. We collected intact soil cores from three land use types (primary rainforest, pasture, and secondary rainforest) of two geographically distinct areas of the Brazilian Amazon (Santarém, Pará and Ariquemes, Rondônia) and performed DNA stable-isotope probing coupled with metagenomics to identify the active methanotrophs and methanogens. At both locations, we observed a significant change in the composition of the isotope-labeled methane-cycling microbial community across land use types, specifically an increase in the abundance and diversity of active methanogens in pastures. We conclude that a significant increase in the abundance and activity of methanogens in pasture soils could explain the greater methane flux. Furthermore, we found that secondary rainforests recovered as methane sinks, indicating the potential for reforestation to offset greenhouse gas emissions in the tropics. These findings are critical for informing land management practices and global tropical rainforest conservation.

AbstractCarotid atherosclerosis is one of the main causes of stroke, mortality and disability worldwide. The disease is characterized by plaques, heterogeneous depositions of lipids and necrotic debris in the vascular wall, which grow gradually and may remain asymptomatic for decades. However, at some point a plaque can evolve to a high-risk plaque phenotype, which may trigger a cerebrovascular event. Lipids play a key role in the development and progression of atherosclerosis. Using matrix-assisted laser desorption/ionization mass spectrometry imaging, we visualized the distribution of approximately 200 lipids in 106 tissue sections of 12 human carotid atherosclerotic plaques. We performed unsupervised classification of the mass spectrometry dataset, as well as a histology-driven multivariate analysis. These data allowed us to compare the spatial lipid patterns with morphological plaque features that have been associated with enhanced risk of symptoms. The abundances of sphingomyelin and oxidized cholesteryl ester species were elevated specifically in necrotic intima areas, while diacylglycerols and triacylglycerols were spatially correlated to areas containing the coagulation protein fibrin. This is the first study to systematically investigate spatial lipid patterns in atherosclerosis, analyze their relation to histological tissue type, and to demonstrate a clear co-localization between plaque features and specific lipid classes and individual lipid molecules in high-risk atherosclerotic plaques.

Published: March 2020

PurposeConsidering the varied and dynamic workload of vessel traffic service (VTS) operators, design an adaptive rotating shift solution to prevent them from getting tired while ensuring continuous high-quality services and finally guarantee a benign maritime traffic environment.Design/methodology/approachThe problem of rotating shift in VTS and its influencing factors are analyzed first, then the framework of automatic identification system (AIS) data analytics is proposed, as well as the data model to extract spatial–temporal information. Besides,K-means-based anomaly detection method is adjusted to generate anomaly-free data, with which the traffic trend analysis and prediction are made. Based on this knowledge, strategies and methods for adaptive rotating shift design are worked out.FindingsIn VTS, vessel number and speed are identified as two most crucial factors influencing operators' workload. Based on the two factors, the proposed data model is verified to be effective on reducing data size and improving data processing efficiency. Besides, theK-means-based anomaly detection method could provide stable results, and the work shift pattern planning algorithm could efficiently generate acceptable solutions based on maritime traffic information.Originality/valueThis is a pioneer work on utilizing maritime traffic data to facilitate the operation management in VTS, which provides a new direction to improve their daily management. Besides, a systematic data-driven solution for adaptive rotating shift is proposed, including knowledge discovery method and decision-making algorithm for adaptive rotating shift design. The technical framework is flexible and can be extended for managing other activities in VTS or adapted in diverse fields.

PurposeA large number of competitors springing up at the same time is a unique phenomenon to emerging markets. How to promote product sales and improve platform performance through appropriate advertising communication strategies is not only an actual problem for the P2P platforms that are committed to long-term and stable operations but also an academic problem in marketing.Design/methodology/approachThis study collected a total of 1960 pieces of panel data of the P2P platforms and constructed a panel data analysis model after filtering.FindingsThe empirical analysis reveals the following: the prevention-focus advertising has a greater impact on platform trading volume, compared with the promotion-focus advertising, and the impact is positively significant; the platform which has a third-party cooperation should use promotion-focus advertising, while prevention-focus advertising is a better choice for the platform without a third-party cooperation. Furthermore, the effects of prevention-focus advertising and promotion-focus advertising on the platforms using individual projects and platforms using organization projects differ.Originality/valueThe results of this study have some reference to the selection of advertising communication strategies for the high-risk financial products.
A comparative study on disqualification of company directors in the UK and Nigeria:
Authors: Caliskan Samet , Subai Pereowei 
Published: March 2020

Purpose
The purpose of this paper is to argue that the disqualification of directors, coupled with other liabilities to which they may be subjected, particularly in insolvency, should be sufficient to deter wrongdoing, because of the impact they tend to have on their personal and professional lives. It, however, argues that the “deterrence” effect would be dependent on the existence of other factors such as the efficient application of the law, publicity and post-disqualification monitoring.

Design/methodology/approach
Using the UK as its primary case study, while also making reference to Nigeria and Turkey, this paper will show that while the existence of disqualification as a sanction exists in the first two countries, it is virtually absent from Turkey. And that while directors’ disqualification provisions are routinely applied in the UK, they are hardly invoked in Nigeria, except perhaps with respect to listed companies, due perhaps to a lack of awareness of its existence or potency.

Findings
This paper will conclude by making a case for a stronger application of the law, as it relates to directors’ disqualification in the UK, call for an elaboration of the legal framework in Nigeria as well as the need for a public awareness of its provisions and potential impact and contend that Turkey should put in place a legal framework for directors’ disqualification patterned also after the UK framework.

Originality/value
The uniqueness of this paper stems from its tri-country focus. In that respect, the UK, which is a more advanced economy, with a robust and dynamic company law regime, is used as the primary case study, whereas at the same time, developments in Nigeria, particularly with that country’s capital market, will be extracted and compared with the UK framework. Turkey, on the contrary, has been chosen as a case study mainly because it has no directors’ disqualification mechanism in its legal system. Comparing directors’ disqualification in one developing country, Nigeria, and a developed country, the UK and determining their upsides and downsides will be beneficial to Turkey in respect to establishing a deterrent effective disqualification mechanism on directors.

Published: March 2020

PurposeThis systematic literature review analyzes and identifies research areas where researchers have already studied the role of intellectual capital (IC) in the healthcare sector. This review also analyzes how they carried out their work to understand future research directions.Design/methodology/approachThe analysis is conducted through a systematic literature review. Therefore, following systematic literature review protocol, it was possible to select 225 papers. An analysis of the content was done to identify the main topics debated and understand what components of IC are the most studied by scholars.FindingsThe authors highlight how the components of IC (human capital, structural capital and relational capital) in the healthcare sector have not been discussed with the same frequency and intensity by researchers. The research shows that there are already widely discussed areas, such as structural capital, while other components of IC have remained on the shadow, such as relational capital. Human capital is the most undiscussed component.Research limitations/implicationsThe manual analysis of the articles can be considered a limitation of this work.Originality/valueThis systematic literature review makes several useful contributions. First, it enables others to replicate scientific research, thanks to its clear and transparent process. Second, it identifies the main areas of research and the main research methods. It enables researchers to identify which issues their work should address and suggests possible areas for future research.
Gamifying a situational judgment test with immersion and control game elements
Authors: Landers Richard N. , Auer Elena M. , Abraham Joseph D. 
Published: March 2020

PurposeAssessment gamification, which refers to the addition of game elements to existing assessments, is commonly implemented to improved applicant reactions to existing psychometric measures. This study aims to understand the effects of gamification on applicant reactions to and measurement quality of situational judgment tests.Design/methodology/approachIn a 2 × 4 between-subjects experiment, this study randomly assigned 315 people to experience different versions of a gamified situational judgment test, crossing immersive game elements (text, audio, still pictures, video) with control game elements (high and low), measuring applicant reactions and assessing differences in convergent validity between conditions.FindingsThe use of immersive game elements improved perceptions of organizational technological sophistication, but no other reactions outcomes (test attitudes, procedural justice, organizational attractiveness). Convergent validity with cognitive ability was not affected by gamification.Originality/valueThis is the first study to experimentally examine applicant reactions and measurement quality to SJTs based upon the implementation of specific game elements. It demonstrates that small-scale efforts to gamify assessments are likely to lead to only small-scale gains. However, it also demonstrates that such modifications can be done without harming the measurement qualities of the test, making gamification a potentially useful marketing tool for assessment specialists. Thus, this study concludes that utility should be considered carefully and explicitly for any attempt to gamify assessment.
The entrepreneurship ecosystem in the ICT sector in Qatar: local advantages and constraints
Authors: Ben Hassen Tarek 
Published: March 2020

PurposeThe purpose of this paper is to analyze the characteristics and dynamics of the entrepreneurship ecosystem in the ICT sector in Qatar.Design/methodology/approachThe methodology of this research is based on a literature review and information collected through semistructured interviews with the different stakeholders involved in the entrepreneurship ecosystem in the ICT sector in Qatar.FindingsThe results show that two opposite forces shape the entrepreneurship ecosystem in the ICT sector in Qatar. On one hand, the strong determination and intervention of the Qatari government to diversify the economy by creating a vibrant ecosystem in the ICT sector. On the other hand, entrepreneurs in this sector are still facing some barriers and difficulties, and those issues are tightly related to Qatar's economic characteristics as a rentier state whose economy is driven by hydrocarbon resources.Originality/valueThese findings contribute to the clarification and critical analysis of the current dynamics of the entrepreneurship ecosystem in the ICT sector in Qatar, which would have several policy implications.
Free and for all? A comparative study of programs with user fees in North American and Danish public libraries
Authors: Lenstra Noah , Mathiasson Mia Høj 
Published: March 2020

PurposeAs a research topic within the field of LIS, programs in public libraries are underexplored, and the question of user fees for programs has not previously been addressed.Design/methodology/approachThis article compares data collected from two individually conducted studies of public library programs in North America and Denmark to enrich our understanding of user fees in relation to programs.FindingsThe comparative analysis shows both similarities and deviations regarding the levying of fees for library programs. While paying a fee to attend a program is rather normal in Denmark, it is more of a fringe idea in North America.Research limitations/implicationsBy exploring a previously understudied facet of contemporary public librarianship, this article opens up new avenues for inquiry regarding how the relative accessibility and availability of programs relate to theoretical discussions about programs as public library services.Practical implicationsThis article provides library managers with needed information about how to conceptualize the roles of programs as public library services.Social implicationsAs programming surges to the fore in contemporary public librarianship, the levying of user fees has social implications in terms of social equity and the public library ethos of free and equal access for all.Originality/valueThis article is the first study of user fees for public library programs, as well as among the first cross-national comparisons of programming as a dimension of public librarianship.
“Gender” and “innovation” in facility management: do they matter?
Authors: Staffansson Pauli Karin , Kristoferson Caroline Wigren , Stevenson Anna 
Published: March 2020

PurposeThe purpose of this paper is to contribute to the ongoing discussion on how the field of facility management is changing and the role a regional innovation system (RIS) can take place to support this change, with a specific focus on the role of gender and innovation.Design/methodology/approachThe study builds partly on interactive research, and as a complement, qualitative semi-structured telephone interviews have been conducted.FindingsThe role of gender and innovations in facility management does matter due to the fact that if aiming at creating innovations, it is necessary to break free from established institutions, both formal and informal. Working with gender demands a norm-critical approach, and to be critical towards what we take for granted might create new solutions.Research limitations/implicationsThe study is conducted in a Swedish context.Practical implicationsThis paper brings gender issues in facility management to the forefront in an effort to engage the industry.Originality/valueThe paper contributes to the ongoing discussions how the field of facility management is changing and the importance of including gender in the innovation discussions.
