The influence of transformational leadership on work engagement in the context of learning organization mediated by employees’ motivation

PurposeThis study aims to focus on determining the influence of transformational leadership on work engagement as mediated by employee motivation.Design/methodology/approachThe research findings are based on a quantitative analysis of a survey of 443 full-time employees working in the Guangdong–Hong Kong–Macao Great Bay Area (GBA) of China.FindingsThe positive perception of transformational leadership from employees enables them to accomplish tasks beyond expectations. With the help of structural equation modeling, this study reveals that the influence path of perceptions of transformational leadership on work engagement is partially mediated through employee motivation.Research limitations/implicationsEmployee motivation is not the only mediating factor, other factors mediate the relationship between transformational leadership and work engagement. The problem of sample size and sampling collection, the survey only focuses on samples working in the GBA.Originality/valueThe analysis and results based on data from mainland China, especially the GBA, expands the boundaries of the role of transformational leaders in learning organization and provides additional data support and sources for future relevant research. At the same time, the study of the mediation models between leadership and work engagement also hints more potential possible mediation factors.

The invasive red seaweed, Dasysiphonia japonica, forms harmful algal blooms: Mortality in early life stage fish and bivalves and identification of putative toxins

In recent decades, the rate of introduction of non-indigenous macroalgae has increased. While invasive seaweeds often outcompete native species for substrata, their direct effects on marine life are rarely described. Here, we describe ‘red water’ events caused by the decay of blooms of the invasive red seaweed, Dasysiphonia japonica, in Great South Bay, NY, USA, and the ability of water from such events to induce rapid and significant mortality in larval and juvenile fish (Menidia beryllina, Menidia menidia, and Cyprinodon variegatus) and larval bivalves (Mercenaria mercenaria and Crassostrea virginica). All species studied experienced significant (p<0.05) reductions in survival when exposed to macroalgae in a state of decay, seawater in which the alga was previously decayed, or both. Both bivalve species experienced 50–60% increases in mortality when exposed to decaying D. japonica for ∼ one week, despite normoxic conditions. Among fish, significant increases (40–80%) in mortality were observed after 24 h exposure to decayed D. japonica and one-week exposures caused, on average, 90% mortality in larval M. beryllina, 50% mortality in juvenile (∼3 cm) M. menidia, and 50% mortality in larval C. variegatus. All fish and bivalve mortality occurred under normoxic conditions (dissolved oxygen (DO) >7 mg L–1) and low ammonium levels (< 20 µM), with the exception of C. variegatus, which expired under conditions of decayed D. japonica coupled with reduced DO caused by the alga. Screening of water with decayed D. japonica using liquid chromatography-mass spectrometry revealed compounds with mass-to-charge ratios matching caulerpin, a known algal toxin that causes fish and shellfish mortality, and several other putative toxicants at elevated levels. Collectively, the high levels of mortality (50–90%) of larval and juvenile fish and bivalves exposed to decaying D. japonica under normoxic conditions coupled with the observation of ‘red water’ events in estuaries collectively indicate the red seaweed, D. japonica, can create harmful algal blooms (HABs).

Microplastic prevalence in marine fish from onshore Beibu Gulf, South China Sea

In recent years, microplastics have been widely detected in marine fish and may pose potential risks to fish and human health. Even though microplastic pollution is a critical issue, it represents as yet non-quantified threat for some context in the marine environment. In this study, 271 individuals comprising 32 species of marine fish collected from Beibu Gulf were examined for microplastic prevalence, with an aim to provide data on the abundance, physical classification, and chemical characterization of microplastics in the great bay along South China Sea. The results showed that the occurrence rate of microplastics was 93.7%, and the average abundance of microplastics was 1.02 ± 0.18 items per individual (ranging from 0.03 to 4.00 items per individual). Microplastic accumulation was observed with a great variation in different species, body sizes, living habitats, and feeding habits of marine fishes. The dominant polymers identified by μ-FTIR were polyethylene terephthalate and polypropylene. Fibers, smaller sizes (&amp;lt;1 mm), and transparent color were the major characteristics of the detected microplastics, which might be important factors affecting the bioaccumulation. The present study revealed that microplastics in marine fish is a widespread issue in onshore Beibu Gulf.

Construction of Cultural Soft Power Evaluation Index Education System Policy Based On AHP

Aiming at the low evaluation confidence of the traditional cultural soft power evaluation index system, a new cultural soft power evaluation index system is constructed based on AHP. This paper discusses the connotation and constituent elements of cultural soft power, designs a comprehensive evaluation index system of cultural soft power from the five aspects of cultural cohesion, cultural security, cultural productivity, cultural attraction and cultural influence, and calculates the weight of each index by using AHP analytic hierarchy process, It can be used as a reference for the theoretical research and practical operation of cultural soft power. The experimental results show that the evaluation confidence of the experimental group is significantly higher than that of the control group, which can solve the problem of low evaluation confidence of the traditional cultural soft power evaluation index system. The Bay area economy is the most significant model of current coastal economy, which has been effectively adopted across the globe. Similar natural circumstances and processes have led to several successful models, each with its own unique set of blueprints and philosophies. China's 13th Five-Year Economic and Social Development Plan identifies the Greater Bay Area as consisting of two special administrative areas and nine cities in Guangdong. It serves as both the precursor of China's reform and opening up and the growing pole for economic development in 2016.

Capture of a new for the basin of Peter the Great Bay (Japan Sea) fish species ayu &lt;i&gt; Plecoglossus altivelis &lt;/i&gt; (Temminck &amp; Schlegel, 1846) (Plecoglossidae)

For the first time, natural entry of ayu or sweetfish into the river of Peter the Great Bay basin (Japan Sea) and generally into the waters of Russian Federation is registered. This finding extends the list of fish species and families dwelling in the Russian waters.

Biological characteristic of herring of Peter the Great Bay (Japan Sea)

Herring in Peter the Great Bay (Clupea pallasii) lives on the southern outskirts of the species’ range, is significantly inferior to other Far Eastern herring populations in level of stock, but is periodically able to form a relatively high abundance. A long-term analysis of the lengthage composition showed the presence in this population of fish groups that differ in life cycle duration, puberty time, and population dynamics. Stock level and success of reproductive strategy of herring in Peter the Great Bay determines the coincidence of intrapopulation factors and favorable features of the current climatic phase. In each new background, the population undergoes the initial stage of formation of the corresponding reproductive organization, preceding the increase in abundance.

The effects of proximities on the evolving structure of intercity innovation networks in the Guangdong–Hong Kong–Macao Greater Bay Area: comparison between scientific and technology knowledge

ABSTRACT The various knowledge flows shape and change the regional innovation patterns, which are also influenced by regional conditions. What are the similarities, differences and connections between science and technology linkage, as two different types of knowledge network, deserve to be explored in depth. Drawing on scientific paper co-publications and patent transfer data, we constructed two different types of intercity innovation networks during 2006–2016 in the Guangdong–Hong Kong–Macao Greater Bay Area (GBA), a city region special for its ‘one country, two systems’ structure. After that, we explored the evolutionary characteristics of the networks and further examined the different impacts of multidimensional proximity on scientific collaboration and technology transfer. Our results show that technology transfer is more sensitive to spatial factors, institutional barriers caused by ‘one country, two systems’ is a bigger obstacle to technology transfer between cities, cultural proximity and cognitive proximity have a more significant impact on paper cooperation network. Moreover, geographical proximity can indirectly affect knowledge spillover by acting on the proximity of other dimensions. As for scientific collaboration, social, cognitive and institutional proximities can compensate for the lack of geographical proximity, and cultural proximity frequently goes along with geographical proximity; as for technology transfer, geographical proximity has neither substitutional or complementarity relations with cultural and cognitive proximities, the interrelatedness between geographical and institutional and social proximities are complementarity which is opposed to paper co-publications. This study explores the differences in spillover mechanisms of different knowledge types and contributes to enriching the empirical framework of multidimensional proximities and innovation network researches.

The Influence of Hong Kong-Zhuhai-Macao Bridge on the Development of Urban Agglomeration in the Pearl River Delta

Known as one of the “seven wonders of the modern world”, the Hong Kong-Zhuhai-Macao Bridge connects Hong Kong, Zhuhai, and Macao. The bridge, which lasted 14 years from design to construction, spans the Lingdingyang waters of the South China Sea to the west, connects Macao and Zhuhai artificial islands, and ends at Zhuhai Hongwan. The bridge, which shortens the traffic distance between the three places and allows the economy, culture, and technology of the three places to communicate with each other, opened up a new world. This paper intends to review the process of the construction of the Hong Kong-Zhuhai-Macao Bridge and sort out the expected benefits of the bridge’s opening to traffic. Then, the paper explains the new situation faced by the Hong Kong-Zhuhai-Macao Bridge. Based on the outward service function model of city flow and the interaction strength model, we conduct an empirical study on the economic status of the Guangdong-Hong Kong-Macao Greater Bay Area. This paper analyzes the interaction between the cities which are in the Greater Bay Area and uses panel data to conduct regression analysis to verify the important impact of the Hong Kong-Zhuhai-Macao Bridge on the development of cities in the Pearl River Delta. Finally, conclusions are drawn: Hong Kong-Zhuhai-Macao Bridge is undoubtedly of positive significance to strengthen economic and social ties between the West Bank of the Pearl River and Hong Kong, and Hong Kong has a large economic radiation capacity to the cities that are in the Pearl River Delta and Macao in the construction, finance, transportation, warehousing, and communications industries. And corresponding suggestions are put forward.

Evaluation of the Level of Smart City Construction Based on Guangfo-Shenzhen-Dongguan in the Context of Guangdong-Hong Kong Macao Greater Bay Area

The Guangdong Hong Kong-Macao Greater Bay Area is one of the most open and economically dynamic regions in China. The construction of a new type of smart bay area is an important part of the Guangdong-Hong Kong-Macao Greater Bay Area strategy, and the construction of a smart bay area needs to be closely integrated with international standards and focus on building a smart digital centre in the Greater Bay Area. This study focuses on the development needs, future development trends and construction strategies of smart cities in four city clusters in the Guangdong-Hong Kong-Macao Greater Bay Area from four development perspectives: smart water conservancy, smart cultural tourism, smart transportation and smart healthcare, using data related to the development of smart cities in Guangzhou-Foshan-Shenzhen-Dongguan in recent years, the entropy weighting method is used to determine the weights of 40 indicators, and the TOPSIS evaluation model is applied to evaluate the level of smart city construction in each city. The evaluation of the level of smart city construction in each city was carried out by using the TOPSIS evaluation model, and it was concluded that there were large differences among the cities, and there was a need for city-specific policies and reasonable improvements. The evaluation of the level of smart city development in each city was carried out using the TOPSIS evaluation model.

Urban coral communities and water quality parameters along the coasts of Guangdong Province, China

Coral communities in China's Great Bay Area (GBA) have experienced severe degradation, but only limited information is available about their community structure. We surveyed 20 sites across three regions (Daya Bay, Dapeng Bay, Wanshan Islands) in GBA to provide an updated baseline of these urban coral communities. Live coral cover varied substantially, with the lowest values (<2 %) found inside the highly urbanized Daya Bay, and highest values (40–47 %) from offshore islands that are less affected by human activities. The two sites with the lowest live coral cover had a high percentage of dead coral. Five groups of coral communities could be identified, with most of them characterized by dominance of massive and encrusting coral species. Both coral cover and generic richness were negatively correlated with dissolved inorganic nitrogen in the water column, indicating that nutrient pollution could potentially constrain the development of these urban coral communities.

Migration of Grey Heron from the Peter the Great Bay and the potential transmission routes of avian influenza

Eight nestlings of Grey Heron were captured in the Peter the Great Bay, Primorskii Territory, Russia and were deployed with trackers supporting GPS and Mobile Phone in May 2017. In total, 35,166 records on the locations of the birds were obtained over the study period until November 18, 2019. The tracking data were available for seven birds in autumn 2017, three birds from spring to autumn 2018, two birds in spring 2019, and only a single bird in autumn 2019. We could trace the migration routes accurately and locate the places for feeding and resting of the Grey Heron during the post-nesting period and seasonal migrations. The direction of the migration of the Grey Herons in autumn was southwest, and it was northeast in spring without exception. With tracking data, we found that there were two main patterns of migration of the Grey Heron: fast and delayed migration. The Grey Heron has been frequently reported to be affected by highly pathogenic avian influenza, and thus, a possibility that infected Grey Heron delivers avian influenza virus in East Asia had been discussed.

Совершенствование промысла водных биоресурсов, обладающих положительной реакцией на свет, при использовании синих светодиодов

The article presents the results of the study on the effectiveness of different light sources and their spectrum in commercial catching the aquatic organisms. The proposed method for increasing catch volumes was based on &#x0D; a program of using LEDs with white, green and blue light and monitoring the reaction of the caught aquatic organisms developed by Japanese scientists. In the practice of Russian commercial fishing there are no data found on the response of aquatic organisms to the spectrum and the effectiveness of using white LEDs that were made on the basis &#x0D; of ultraviolet LEDs. There has been given the review of works investigating the reaction to the light spectrum of various hydrobionts living in different ecological niches. It has been found that all hydrobionts under study (herring, pollock, saury, etc.) actively react to the blue spectrum of color, which makes it possible to use blue LEDs as light sources in commercial fishing. Experiments were carried out in Peter the Great Bay (Primorsky Krai, Russia) using &#x0D; a submersible lamp with four blue LEDs. Hydrobionts living in different ecological niches (flounder and Pacific squid) were selected as the objects of study. The flounder has never been fished with light, and Pacific squid is traditionally caught by using light. As a result of experiments, squid catch volumes increased by 32-40%, with additional ship lighting - by 35-42%; flounder catches increased by 167-172% in the evening and up to 211% at night
