Comparing biological classifications of freshwater phytoplankton: a case study from South China

2012

The use of ecological classification systems is becoming more and more widely used when studying phytoplankton. Grouping phytoplankton species into ecologically coherent groups allow to reduce redundancy and in this way, to handle a minor number of biological variables when investigating the ecological status of aquatic ecosystems. Three ecological classifications are mostly used when freshwater phytoplankton is studied: functional groups or coda, morpho-functional groups (MFGs) and morphology-based functional groups (MBFGs). In this study, these three ecological classifications were comparatively used along with two taxonomic classifications based on species and genera to analyse phytoplan…

What drives the adoption and consumption of green hotel products and services? A systematic literature review of past achievement and future promises

2021

The current study utilises the time-tested systematic literature review (SLR) method to identify and analyse 76 studies addressing the consumer adoption of green hotels. The results of the research profile analysis show that the literature on consumers' adoption and consumption of green hotel products and services is expanding and gaining more recognition from researchers working in Asian contexts, particularly China, Taiwan and India. Moreover, the qualitative thematic analysis yields four key themes, (a) consumer behaviour variables addressed, (b) antecedents and mediators of green hotel adoption, (c) moderators of the relationship and (d) methodological considerations, for which limitati…

Improvisation for innovation: The contingent role of resource and structural factors in explaining innovation capability

2018

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. This paper focuses on resource and structural factors to explore the relationship between organizational improvisation and innovation capability. Although the role of improvisation has attracted increasing academic attention in fast-changing environments, little is known about the conditions under which firms benefit from improvisation. This paper addresses this gap using an organizational learning perspective that explains the role of a firm's organizational structure and organizational resources for improvisation and innovation. A large-scale …

Queen loss increases worker survival in leaf-cutting ants under paraquat-induced oxidative stress

2021

Longevity is traded off with fecundity in most solitary species, but the two traits are positively linked in social insects. In ants, the most fecund individuals (queens and kings) live longer than the non-reproductive individuals, the workers. In many species, workers may become fertile following queen loss, and recent evidence suggests that worker fecundity extends worker lifespan. We postulated that this effect is in part owing to improved resilience to oxidative stress, and tested this hypothesis in three Myrmicine ants: Temnothorax rugatulus, and the leaf-cutting ants Atta colombica and Acromyrmex echinatior . We removed the queen from colonies to induce worker reproduction and subjec…

The first record ofDinesus(Trilobita, Dinesidae) in the Cambrian of the Mediterranean region

2011

An important problem facing inter-regional correlation in the Cambrian is the scarcity of shared taxa between different palaeogeographic domains. Currently, species of the Corynexochida are proposed as tools to define the base of Cambrian Series 3. However, few Mediterranean Corynexochida species are known. A specimen of Dinesus truyolsi comb. nov. from the middle Cambrian of Spain represents the first record of this genus in the Acadobaltic province. Erbia and Tingyuania are accepted as junior subjective synonyms of Dinesus, and we now recognize 22 species within this genus. Dinesus has been found previously in lower to middle Cambrian strata of Australia, Russia, Kazakhstan, North America…

Patterns of Old World Hipparionine Evolutionary Diversification and Biogeographic Extension

1990

Hipparionine horses have long been united evolutionarily by the presence of three toes per digit, having high crowned cheek teeth with cement, and isolated proto-cones on upper cheek teeth (Christol, 1832). Geochronologically they have further been recognized as the preeminent large mammal “index” fossils for late Neogene Old World deposits. Their abundance in later Neogene mammal faunas has prompted the production of a staggering body of systematic and interpretive literature during the last 150 years. In the last 40 years there has been an increasing number of attempts to reorganize parts of Old World hipparionine systematics by regional studies of variable scope including Europe in gener…

Cross-cultural analysis of teacher confirmation, student motivation, classroom emotion and emotional interest in China, Korea and Japan

2016

This study investigates the relationship between teacher confirmation and student motivation across three cultures: China, Korea, and Japan and studies how classroom emotion and emotional interest influence this relationship in three different countries. Students in China (n=718), Korea (n=362), and Japan (n=350) completed questionnaires assessing their perceived teacher confirmation, student motivation, classroom emotion and emotional interest. Results of these samples indicate that teacher confirmation is positively correlated with student motivation in Korea and Japan. There is also a significant difference in these three groups on teacher confirmation, emotional support and emotional wo…

DISCUSSION ON THE RELATIONSHIP BETWEEN DEEP SEISMIC REFLECTION PATTERNS AND TECTONIC UNITS OF THE EASTERN PART OF THE CENTRAL ASIAN OROGENIC BELT IN …

2017

Division of tectonic units in the eastern part of the Central Asian Orogenic Belt in northeast China has been a major concern and resulted in much fieldwork, but the division of these tectonic units in NE China is still controversial. Although detection of tectonic units in seismic sections is not straightforward, for this meeting, we shall try to relate tectonic units with the crustal and upper mantle structure and deformation derived from a ~2500 km long reflection seismic profile (Figure, red lines) in this area, recently acquired or reprocessed with support of China Geological Survey and the Chinese SinoProbe Project.

Modeling NAFLD Disease Burden in China, France, Germany, Italy, Japan, Spain, United Kingdom, and United States for the period 2016-2030

2018

Background & Aims: Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are increasingly a cause of cirrhosis and hepatocellular carcinoma globally. This burden is expected to increase as epidemics of obesity, diabetes and metabolic syndrome continue to grow. The goal of this analysis was to use a Markov model to forecast NAFLD disease burden using currently available data. Methods: A model was used to estimate NAFLD and NASH disease progression in eight countries based on data for adult prevalence of obesity and type 2 diabetes mellitus (DM). Published estimates and expert consensus were used to build and validate the model projections. Results: If obesity and…
