EquiCity game: a mathematical serious game for participatory design of spatial configurations

We propose a mathematical framework for developing social-choice games that are designed to mediate decision-making processes for city planning, urban area redevelopment, and architectural configuration of urban housing complexes. The proposed framework features a digital serious gaming approach for participatory design to support transparency and inclusion in the process of decision-making and ensure an equitable balance of sustainable development goals in spatial design outcomes. The mathematical process consists of a Markovian design machine for balancing the design decisions of actors, a massing configurator equipped with fuzzy logic and multi-criteria decision analysis, algebraic graph-theoretical accessibility evaluators, and automated solar-climatic evaluators using geospatial computational geometry. We demonstrate the effectiveness of the framework by implementing a multi-player online game that facilitates a participatory decision-making workshop for forming multi-functional building complexes by providing a generative configurator equipped with automated appraisal/scoring mechanisms for revealing the aggregate impact of alternatives. The EquiCity game empowers a group of decision-makers to reach a fair consensual spatial design by mathematically simulating many rounds of reasonable trade-offs between their decisions, with different levels of interest or control over various types of investments. The novelty of the framework is in its capability to encompass decision-making about the most idiosyncratic aspects of a site related to its heritage status and cultural significance to the most generic aspects such as balancing access to sunlight for the site while respecting ‘the right to sunlight’ of the neighbours of the site, ensuring coherence of the entire configuration with regards to a network of desired closeness ratings, the satisfaction of a programme of requirements, and intricately balancing individual development goals in conjunction with communal goals and environmental design codes.

The walking dead: Identity, variability, and cultural interactions of funerary behaviors between Crete and mainland Greece during the Early Iron Age (11th to 8th BC)

This paper aims to examine funerary contexts of sites in mainland Greece and compare them with sites on the island of Crete in Ancient Mediterranean during the Early Iron Age, in the period of circa the 11th until the 8th centuries BC. From an integrative approach to the analysis and interpretation of material culture from funerary contexts allow us to understand aspects of the space of the dead, aspects of mortuary practices and their role in the configuration of the historical context of the rise and formation of the polis, especially during the 8th century BC. The comparative analyses also provide a better understanding about contact and interactions in the Mediterranean. This requires us to analyze and consider on the different nature of material culture from funerary contexts, such as types of treatment and deposition/disposal/placement of the body of the dead, the construction of funerary architecture, grave goods, and the agency of the space of the dead in the construction of the funerary topography (funerary landscape). Cultural interactions are material expressions resulting from the exchange of ideas, know-how, technique and technology, beliefs, customs, and behaviors, both from objects and from the movement of people. They constitute a prospective field to address mortuary archaeological data as an active part of death and of the social process of dying. Funerary behaviors assign meanings, build memories and identities to biological death. They bring life to the transition of an active person in the “world of the living” into a passive “material thing” in the “world of the dead”. Thus, the dead, become the “walking dead” and “come to life”. Cultural interactions during the Early Iron Age constitute a fundamental element in the configuration of a new historical structure, the polis, which characterizes the Greek world as a unit – not homogeneous but consisting of heterogeneous and idiosyncratic aspects. Mortuary practices integrate this world of simultaneously standardized and peculiar actions and have crucial roles in the hellenic identity and in the identity particularities of its polis in Greek mainland and Crete.

Picturing oneself over time: a multi-modal interpretative phenomenological analysis of pain management trajectories.

Chronic pain (CP) can be a disabling condition with impacts that affect the sense of identity of those who live with it. This article idiographically describes the longitudinal evolution of the sense of self of participants following their referral to a pain management service and participation in a pain management programme (PMP). Participants were interviewed three times: before they attended a PMP, and 1 and 6 months after the PMP. Data included the drawings of themselves that participants created at each interview and the transcripts of the interviews guided by the drawings, analysed longitudinally using interpretative phenomenological analysis. This paper describes in detail the cases of four participants: two who experienced a positive albeit troubled trajectory following their PMP and two who did not experience any positive change. The results provide a nuanced account of how the impacts of CP on identity can evolve, with different people engaging with different aspects of a PMP and some people not engaging at all, and how pain self-management strategies enable those that do engage to cope in times of difficulty. Participant responses to PMP participation are idiosyncratic and interviews with drawings of self analysed longitudinally can help illustrate processes of change. Not enough is understood about why some people get limited benefits from pain services. This idiographic longitudinal study illustrates how the impact of CP on identity can evolve when people are introduced to pain self-management, with some embracing change and others resisting it. For clinicians, this study describes four detailed CP individual paths, showing the interaction between contextual and idiosyncratic aspects. This is also the first study to use multiple drawings of self to explore the impacts of illness on identity longitudinally. In a person-centred approach to treatment, the drawings of self could also be adopted as a tool in clinician-patient conversations to gain a deeper understanding of the impacts of living with CP.

Three noteworthy idiosyncrasies related to Canada's opioid-death crisis, and implications for public health-oriented interventions.

Canada has been experiencing a prolonged public health-crisis of high rates of overdose deaths caused by exceptionally potent/toxic, illicit opioid use. While many key features of this drug death epidemic are well-documented, several idiosyncratic aspects with relevance for public health-oriented interventions are not adequately recognised. These include: (i) the discrepant opioid patterns pan-Canada, with large majorities of opioid deaths caused by illicit fentanyl drugs in Western, but not Eastern regions where prescription-type opioid prevail; (ii) the environments of overdose deaths, where vast majorities occur in 'residential' or other shelter-type settings, presenting barriers for emergency interventions rather than health protection; and (iii) shifting drug use modes, where now majorities of overdose deaths are associated with drug 'inhalation' (instead of 'injection') in contexts of potent/toxic drug supply. We briefly describe these factors and related implications for intervention programming towards an improved response to the drug death-crisis.

Idiosinkrasi Manuskrip Mushaf Al-Qur'an di Desa Rejoagung Ngoro Jombang

The historical traces of the spread of Islam throughout the archipelago cannot be separated from the existence of ancient manuscripts, which are one of Indonesia's assets. This paper discusses the study of manuscripts in the form of mushafs of the Qur'an in a village in Jombang district, namely Rejoagung Village. The problem that will be answered in this article is regarding the physical characteristics of the manuscripts of the Al-Qur'an in Rejoagung Village and the idiosyncratic aspects of their textology. Some of the things that the author will examine are the forms of rasm, dabt, and the verse numbering system. The method used is the single manuscript method with critical editions in the study of ancient manuscripts. The result of this research is that this manuscript has a different idiosyncratic style from the Mushaf Al-Qur'an manuscripts in Indonesia. Rasm used is a mixture of usmani and imla'i. The verse termination system does not adhere to a Kufah school of thought, which is familiar in the copying of the Qur'an in the archipelago. This shows that the copyist applied idiosyncrasy in the process of copying. Follow-up research is needed to obtain a description of the different patterns of the process of copying the Al-Qur'an mushaf from various ancient manuscripts spread across Nusantara.

Hemispheric Asymmetries of Individual Differences in Functional Connectivity.

Resting-state fMRI studies have revealed that individuals exhibit stable, functionally meaningful divergences in large-scale network organization. The locations with strongest deviations (called network "variants") have a characteristic spatial distribution, with qualitative evidence from prior reports suggesting that this distribution differs across hemispheres. Hemispheric asymmetries can inform us on constraints guiding the development of these idiosyncratic regions. Here, we used data from the Human Connectome Project to systematically investigate hemispheric differences in network variants. Variants were significantly larger in the right hemisphere, particularly along the frontal operculum and medial frontal cortex. Variants in the left hemisphere appeared most commonly around the TPJ. We investigated how variant asymmetries vary by functional network and how they compare with typical network distributions. For some networks, variants seemingly increase group-average network asymmetries (e.g., the group-average language network is slightly bigger in the left hemisphere and variants also appeared more frequently in that hemisphere). For other networks, variants counter the group-average network asymmetries (e.g., the default mode network is slightly bigger in the left hemisphere, but variants were more frequent in the right hemisphere). Intriguingly, left- and right-handers differed in their network variant asymmetries for the cingulo-opercular and frontoparietal networks, suggesting that variant asymmetries are connected to lateralized traits. These findings demonstrate that idiosyncratic aspects of brain organization differ systematically across the hemispheres. We discuss how these asymmetries in brain organization may inform us on developmental constraints of network variants and how they may relate to functions differentially linked to the two hemispheres.

Consistently Inconsistent Perceptual Illusions in Nonhuman Primates: The Importance of Individual Differences.

Perceptual illusions, and especially visual illusions, are of great interest not only to scientists, but to all people who experience them. From a scientific perspective, illusory visual experiences are informative about the nature of visual processes and the translation of sensory experiences to perceptual information that can then be used to guide behavior. It has been widely reported that some nonhuman species share these illusory experiences with humans. However, it is consistently the case that not all members of a species experience illusions in the same way. In fact, individual differences in susceptibility may be more typical than universal experiences of any given illusion. Focusing on research with the same nonhuman primates who were given a variety of perceptual illusion tasks, this "consistent inconsistency" is clearly evident. Additionally, this can even be true in assessments of human illusory experiences. Individual differences in susceptibility offer an important avenue for better understanding idiosyncratic aspects of visual perception, and the goal of isolating any possible universal principles of visual perception (in primates and beyond) should address these individual differences.

Grammatically relevant aspects of meaning and verbal polysemy

AbstractThe debate over the relation between grammatically relevant (specifically, what we termevent referential) and idiosyncratic aspects of verb meaning has produced a considerable literature. Some authors, such as Levin and Rappaport Hovav, have appealed to figurative uses of verbs as a source of data when the analysis of their literal uses has been controversial, a move that has sometimes been criticized. However, the question of whether figurative uses of verbs preserve the event referential properties of their literal counterparts and are therefore a valid source of data has not, to our knowledge, been systematically explored. We offer two detailed cross-linguistic case studies of Spanish and English verbs to provide an argument that figurative verb uses indeed are a reliable source of evidence for identifying event referential components of meaning: In each case study we find clear evidence for the preservation of these components across uses, indicating that these aspects of meaning both constrain and facilitate figurative uses of verbs.

Suitability of Motivational Regulation Strategies for Specific Motivational Problems

Abstract. Learners utilize a variety of strategies to regulate their motivation. Theoretical models of motivational regulation imply a connection between the decision for a concrete strategy and the specific situational requirements. Accordingly, one would expect that the suitability of a strategy depends on how well it fits the motivational problem in question. Since reliable findings on this point are missing, we conducted a survey of N = 33 proven experts in the field of self-regulated learning to enlighten the suitability of nine strategies for six different motivational problems. Our findings showed that the suitability of a group of strategies was consistently considered dependent on the given motivational problem (e. g., ability-focus self-talk was suitable to enhance motivation for a difficult task) – pointing to the importance of conditional strategy knowledge for learners. For another group of strategies, experts’ suitability judgments were indifferent, indicating that strategy suitability may also comprise idiosyncratic (i. e., person-specific) aspects.

Peer-to-peer accommodation prices: City listing concentration and host listing share

This article examines the relationship of city listing concentration and host listing share with prices in the peer-to-peer accommodation market. To this end, a multilevel analysis is applied to data from 216,960 Airbnb listings in 45 cities. The results reveal that while city-level concentration does not significantly affect prices, the listing share of each supplier does have a significant effect. This highlights that host listing shares can explain the ability of agents to influence the price of their accommodations even in relatively competitive markets such as peer-to-peer accommodation. Our findings have theoretical implications relating to the idiosyncratic aspects that affect business pricing, as well as practical implications in the private sphere for the rest of the hospitality and tourism industry, and for public policy in terms of regulations.

Plus ça change? Translating William Gibson into Polish: “The Gernsback Continuum” and The Peripheral

This article has been inspired by the most recent Polish edition of William Gibson’s 1986 collection of short stories Burning Chrome. By focusing on the new Polish translation of one of Gibson’s earliest tales, “The Gernsback Continuum,” and juxtaposing it with the Polish version of his latest novel, The Peripheral, I intend to comment on the reception of his prose (both by the source culture and the target culture readers) and its translatability. Apart from the idiosyncratic aspects of Gibson’s work in general, various extraliterary factors will also be taken into account in order to elucidate the context in which Polish translations of his works continue to be created, distributed and assessed.

Does Perceived Corruption Converge? International Evidence

Abstract This article analyses the evolution over time of perceived corruption for a large set of countries worldwide. To proxy corruption, we use the recently proposed Bayesian Corruption Index (Standaert, S. (2015). Divining the level of corruption: A bayesian state space approach, Journal of Comparative Economics, 43(3), 782–803). We employ the test developed by (Phillips, P., & Sul, D. (2007). Transition modeling and econometric convergence tests. Econometrica, 75, 1771–1855) that enables the endogenous determination of convergence clubs for countries over time. Having divided countries into convergence clubs, we explore whether each club differs from the others in terms of their competitiveness ranking. In particular, drawing on the 2019 Global Competitiveness Report, we focus not only on the global competitiveness score, but also on the first and the fifth pillars of competitiveness: institutions and health, respectively. Mean and median scores for clubs confirm the general rule that low perceived corruption levels tend to be associated with high-income countries with established democracies, high-quality healthcare systems, and relatively low-income inequality. However, countries such as Spain and Italy, which are innovation-driven economies with excellent scores in the health pillar, are in the worst club for perceived corruption, suggesting there are additional idiosyncratic aspects that could drive perceived corruption levels.

Labour law without labour law: The United Kingdom’s labour market response to COVID-19

The United Kingdom’s response to the COVID-19 crisis with respect to labour law and protecting workers and working relationships had several idiosyncratic aspects that distinguished it from ostensibly similar attempts to protect jobs during the pandemic. The UK approach was striking, in comparative terms, due to its lack of engagement with any process of social dialogue at the national, sectoral, and enterprise levels. The structures of worker representation of this type are so weak in the UK, due in part to a particular tradition of collective bargaining, that any such involvement would possibly not even have been feasible given the short time frame without the creation of new ad hoc infrastructure. While most other advanced economies made use of relatively familiar methods of labour law, alongside macroeconomic intervention and state support, the UK’s response was largely devoid of any traditional labour law content, and did not make use of labour law categories or methods, in particular the placing of obligations on the employer. this meant that the UK’s approach reflected a form of “labour market” regulation which aimed, unusually, at solidifying rather than deregulating the labour market. While this approach comes with many significant complexities and risks, it provides a potential model for future interventions which do not rely on sometimes tired or outdated labour law categories.

Geomorphic impacts of Hurricane Florence on the lower Neuse River: Portents and particulars

In September 2018 Hurricane Florence had severe impacts on the lower Neuse River and Neuse estuary, North Carolina, despite the fact that it was a minor storm in terms of traditional indicators of storm intensity. The storm was consistent with recent trends and predictions of tropical cyclone activity driven by Anthropocene climate warming. However, its impacts in the Neuse area were also conditioned by idiosyncratic aspects of the geographic setting and the synoptic situation. Geomorphic changes examined here include erosion of estuarine shoreline bluffs, geomorphic transformations of small freshwater swamps, and effects on the river and floodplain upstream of the estuary. The shoreline changes caused by Florence were unique with respect to previous tropical cyclones and ongoing episodic erosion, due to the extraordinarily high and unusually long duration of storm surge. Transformations of the “ravine swamps”—mainly associated with deposition of >0.6 m of sand on organic muck and open water surfaces—were similarly unprecedented. Despite high river discharges (third highest on record) and the high storm surge, fluvial impacts in the lower river and fluvial-estuarine transition zone were minimal. This is attributable to the morphology of the channel-floodplain system, adapted to Holocene sea-level rise and preserved by wetlands protection programs. The large area of the storm, slow forward movement, and extreme rainfall of Florence are likely indicative of a “new normal” with respect to tropical cyclones in the region. However, the geomorphic impacts in the lower Neuse were largely determined by particulars of the Neuse estuary and Florence's storm track. An exception is the limited impacts on the lower fluvial portion of the river and the fluvial-estuarine transition zone, where there exists a complex mosaic of channels and flowing wetlands capable of accommodating extreme discharges.

Combating pandemic: an exploration of social media users’ risk information seeking during the COVID-19 outbreak

The world is currently experiencing an unprecedented pandemic crisis. To explore public’s information behaviors in response to the COVID-19 outbreak, this study aims 1) to empirically explore determinants of information seeking behaviors during COVID-19 by testing the framework of risk information seeking (FRIS), and 2) to assess the model under social media context by integrating social media engagement into the original variable in the model, given that the social situation of COVID-19 and the new media environment has changed how people engage with their community and seek information. As a result of conducting an online survey and testing the proposed hypotheses, the study found acceptable model fits from both the measurement model and structural model. This research presents novel findings on what instigates lay public to seek information during the pandemic crisis: 1) Pathways that consistently supported the original framework’s findings suggest how social media engagement can generate a virtual involvement with the issue to an extent which induces similar level of affective and behavioral responses; 2) media saturation and overflowing information channels omitted the mediating role of information need between current knowledge and information seeking; 3) individuals with higher social media engagement demonstrate higher seeking intent, mediated by negative emotion and social pressure. Overall, by applying the new media setting and the COVID-19 context to a pre-existing information seeking model, this article asserts the need for more pragmatic risk communication strategies that encompass the idiosyncratic aspects of pandemic crisis and the public’s information behaviors in a new media landscape.

Using the Work Experience Survey and the Job Accommodation Network to Identify Reasonable Accommodations in the Workplace: Case Studies of African American Women With Multiple Sclerosis

PurposeFour African American women with multiple sclerosis (MS) participated in an evaluation of barriers to their continued employment.MethodsA trained interviewer completed the Work Experience Survey (WES) in teleconsultation sessions with each participant to identify their: (a) barriers to worksite access, (b) difficulties performing essential functions of their positions, (c) concerns regarding continued mastery of their careers, and (d) extent of job satisfaction.ResultsResulting largely from the physiological, sensory, and cognitive sequelae of their disease, participants reported a wide range of difficulties in performing essential functions of their jobs (15–45) that have the potential to significantly affect their productivity. Career mastery problems reflected issues associated with MS such as “believing that others think I do a good job” and “having the resources (e.g., knowledge, tools, supplies, and equipment) needed to do the job.” Other career mastery concerns reflected idiosyncratic aspects of a specific job setting such as “being able to speak with my supervisor about promotion.” Considering these barriers and relationships with employers, the majority of participants reported low levels of job satisfaction.ConclusionThe interviewer concluded the WES interview by recommending a job accommodation plan, which included suggestions from Job Accommodation Network (JAN) consultants. The interviewer also offered guidelines for the employee to follow in requesting job modifications and assistive technology.

Interwoven traditions in Bell Beaker metallurgy: Approaching the social value of copper at Bauma del Serrat del Pont (Northeast Iberia).

Debates on early metallurgy in Western Europe have frequently focused on the social value of copper (between utilitarian and symbolic) and its purported role in the emergence and consolidation of hierarchies. Recent research shows that generalisations are increasingly untenable and highlights the need for comparative regional studies. Given its location in an intermediate area, the early metallurgy of Northeast Iberia provides an interesting case in point to explore the interaction between the well-characterised traditions of southern Iberia and southern France during the 3rd and 2nd millennia BCE. Here the analytical study of seven Bell Beaker (decorated and undecorated) vessels reused as crucibles at Bauma del Serrrat del Pont (Tortellà, Girona) are presented. We employed pXRF, metallography, SEM-EDS and lead isotope analyses. The results show evidence for copper smelting employing a remarkable variety of ore sources, including Solana del Bepo, Turquesa and Les Ferreres mines, and an extra unknown area. The smelting vessels were manufactured using the same clay, which contained both mineral and organic inclusions. Our results are discussed with reference to all the evidence available for metals and metallurgy in the Northeast, and more broadly in comparison to southern Iberia and southern France, with special emphasis on issues of production organisation and social complexity. Taken together, our results support the notion that copper metallurgy played a predominantly utilitarian role in Bell Beaker societies and highlight idiosyncratic aspects of the metallurgical trajectory in the Northeast. Differences between territories challenge unilinear explanations of technological and social development after the introduction of metallurgy. Separate trajectories can only be explained in relation to area-specific socio-cultural and environmental factors.

Uncertainty in the modelled mortality of two tree species (Fraxinus) under novel climatic regimes

AbstractAimBased upon species distribution models (SDMs), many studies have predicted that climate change will cause regional extinctions of tree species within the next 50–100 years. SDM‐based predictions have been challenged on procedural and theoretical grounds, but for tree species they are largely beyond the practical reach of direct experimental validation. Here we report the experimental consequences of moving seedlings from ~50 natural populations of each of two ash (Fraxinus) species to experimental sites spanning a range of 10°C colder to 10°C warmer (mean annual temperature) than home environments.LocationEastern North America.MethodsWe measured population‐by‐test‐site survival percentages and mean trunk diameters at an average age of 35 years. We then used linear, mixed‐effect models to develop transfer functions for each species and predict survival and mean annual growth as functions of fixed and random effects including, especially, the climatic distance (CD) between test site and home environment.ResultsSurvival and growth were highest at CD ≈ 0 and declined as populations were moved to warmer or colder environments, indicating that survival and growth were optimal when populations were in home‐like climates. However, variance around the model fit was substantial, and we could not statistically detect, even at α = .50, elevated mortality following displacements into environments 3.5°C (white ash) and 4.1°C (green ash) warmer in mean annual temperature. Survival rates of 80%–100% were common even within populations subjected to warming conditions greater than those predicted to cause meso‐scale extinctions in this century. We show that within‐population genetic variance, phenotypic plasticity and idiosyncratic aspects of the non‐climatic environment and its interaction with genotype each likely contributed to these unexpected responses to climatic displacement.Main conclusionsResults emphasize the uncertainty that underlies predictions of climate‐induced extinctions of long‐lived woody plants over time frames of 50 to perhaps 100 years into the future.

Levels and dimensions of diversity in small businesses: contributions for performance

PurposeThe purpose of this study is to propose and test a model on the impact of diversity over performance using a Portuguese national wide comprehensively matched employee–employer dataset of small businesses.Design/methodology/approachThe study uses structural equation modeling to analyze the relationships between variables. The study addresses the impact of top managers and employees' diversity on firm performance considering two dimensions of diversity: knowledge diversity and social diversity.FindingsThe study provides a clear understanding of how workforce diversity affects performance differently at the two hierarchical levels. Both employees' diversities have stronger relations to performance than the diversity of top managers. Results point out to idiosyncratic aspects of services firms' dynamics that should be further explored.Research limitations/implicationsThe study presents some limitations, since it uses data from a single country and the dataset provides limited variables.Practical implicationsThe study offers evidence on the effects of diversity in small businesses alerting managers to acknowledge such influence when recruiting, selecting and training. With regard to services firms, managers should pay close attention to negative impacts of diversity over performance.Originality/valueNever before to the authors' knowledge the managers' level diversity and employees' level diversity (considering two dimensions each) effect on performance have been addressed in a single national wide study.

Impact of Pleistocene Eustatic Fluctuations on Evolutionary Dynamics in Southeast Asian Biodiversity Hotspots.

Pleistocene climatic fluctuations (PCF) are frequently highlighted as important evolutionary engines that triggered cycles of biome expansion and contraction. Although there is ample evidence of the impact of PCF on biodiversity of continental biomes, the consequences in insular systems depend on the geology of the islands and the ecology of the taxa inhabiting them. The idiosyncratic aspects of insular systems are exemplified by the islands of the Sunda Shelf in Southeast Asia (Sundaland), where PCF-induced eustatic fluctuations had complex interactions with the geology of the region, resulting in high species diversity and endemism. Emergent land in Southeast Asia varied drastically with sea-level fluctuations during the Pleistocene. Climate-induced fluctuations in sea level caused temporary connections between insular and continental biodiversity hotspots in Southeast Asia. These exposed lands likely had freshwater drainage systems that extended between modern islands: the Paleoriver Hypothesis. Built upon the assumption that aquatic organisms are among the most suitable models to trace ancient river boundaries and fluctuations of landmass coverage, the present study aims to examine the evolutionary consequences of PCF on the dispersal of freshwater biodiversity in Southeast Asia. Time-calibrated phylogenies of DNA-delimited species were inferred for six species-rich freshwater fish genera in Southeast Asia (Clarias, Channa, Glyptothorax, Hemirhamphodon, Dermogenys, Nomorhamphus). The results highlight rampant cryptic diversity and the temporal localization of most speciation events during the Pleistocene, with 88% of speciation events occurring during this period. Diversification analyses indicate that sea-level-dependent diversification models poorly account for species proliferation patterns for all clades excepting Channa. Ancestral area estimations point to Borneo as the most likely origin for most lineages, with two waves of dispersal to Sumatra and Java during the last 5 myr. Speciation events are more frequently associated with boundaries of the paleoriver watersheds, with 60%, than islands boundaries, with 40%. In total, one-third of speciation events are inferred to have occurred within paleorivers on a single island, suggesting that habitat heterogeneity and factors other than allopatry between islands substantially affected diversification of Sundaland fishes. Our results suggest that species proliferation in Sundaland is not wholly reliant on Pleistocene sea-level fluctuations isolating populations on different islands.
