The role of national intellectual capital in the digital transformation of EU countries. Another digital divide?

Purpose: This study, an exploratory one, aims to empirically investigate the association of national intellectual capital (NIC) with the national digital transformation readiness of the European Union's (EU’s) member states. Apart from building the conceptual model of NIC, this study explores the role of NIC dimensions in the digital divide between European countries. Design/methodology/approach: Based on the literature review and the available EU statistical data and indexes, the theoretical framework and conceptual model for NIC were developed. The model explores the relation of NIC and its dimensions (human, social, structural, relational and renewable/development capital) on the readiness of European countries for digital transformation and the digital divide. Significant differences between EU countries in NIC and digital readiness were tested. Multiple linear regression was used to explore the association of each NIC dimension with digital transformation and digital divide within the EU. Findings: Despite a positive association between all dimensions of NIC and digital transformation readiness, the proposed model of NIC was not confirmed in full. Regression analysis proved social capital and working skills, a dimension of human capital, to be the predictors of digital transformation at a national level, able to detect certain elements of digital divide between EU member states. Structural capital, knowledge and education, as dimensions of human capital, were predictors of the digital divide in terms of the integration of digital media in companies. Research limitations/implications: This research has a limited propensity for generalisation due to the lack of common measurement models in the field of NIC exploration. Practical implications: This research offers policy makers an indication of the relationships between NIC and digital transformation, pointing out which dimensions of NIC should be strengthened to allow the EU to meet the challenges of digital economy and to overcome the digital divide between EU member states. Social implications: The use of digital technologies is key in creating active and informed citizens in the public sphere and productive companies and economic growth in the business sphere. Originality/value: This study provides an original theoretical framework and conceptual model through which to analyse the relationship between NIC and digital transformation, which has thus far not been explored at the level of the EU. This research makes an original contribution to the empirical exploration of NIC and produces new insights in the fields of digital transformation and intellectual capital

Exploring the financial and investment implications of the Paris Agreement

A global energy transition is underway. Limiting warming to 2°C (or less), as envisaged in the Paris Agreement, will require a major diversion of scheduled investments in the fossil-fuel industry and other high-carbon capital infrastructure towards renewables, energy efficiency, and other low or negative carbon technologies. The article explores the scale of climate finance and investment needs embodied in the Paris Agreement. It reveals that there is little clarity in the numbers from the plethora of sources (official and otherwise) on climate finance and investment. The article compares the US$100 billion target in the Paris Agreement with a range of other financial metrics, such as investment, incremental investment, energy expenditure, energy subsidies, and welfare losses. While the relatively narrowly defined climate finance included in the US$100 billion figure is a fraction of the broader finance and investment needs of climate-change mitigation and adaptation, it is significant when compared to some estimates of the net incremental costs of decarbonization that take into account capital and operating cost savings. However, even if the annual US$100 billion materializes, achieving the much larger implied shifts in investment will require the enactment of long-term internationally coordinated policies, far more stringent than have yet been introduced.</i

Copyright @ 2010 Elsevier B.V.Human development should be the ultimate objective of human activity, its aim being healthier, longer, and fuller lives. Thus, if the competitiveness of a nation is properly managed, enhanced human welfare should be the key expected consequence. The research described here explores the relationship between the competitiveness of a nation and its implications for human development. For this purpose, 45 countries were evaluated initially using data envelopment analysis. In this stage, global competitiveness indicators were taken as input variables with human development index indicators as output variables. Subsequently, an artificial neural network analysis was conducted to identify those factors having the greatest impact on efficiency scores

Progress in the synthesis of sustainable polymers from terpenes and terpenoids

The imminent depletion of resources derived from fossil fuels is a major concern for today’s society. 300 Mt of polymers are used every year in the form of plastics, most commonly derived from fossil fuels, hence the necessity to find new materials based on renewable resources. This review explores the utilisation of monoterpenes and terpenoids – a family of abundant and inexpensive natural products – as promising renewable monomers. Terpenes can be directly used in polymerisations or converted into bespoke monomers through organic transformations. The use of terpenes for the production of renewable plastics has been a prevalent topic of research for the past few decades. Early research focused on cationic polymerisation of terpenes by way of their alkene moieties; however, more recently terpenes are being functionalised to incorporate handles for a larger range of polymerisation techniques. Herein an assessment of the future prospects for the use of these small functional molecules to synthesise novel and valuable renewable materials is presented

Phycoremediation of municipal wastewater by microalgae to produce biofuel

Municipal wastewater (WW), if not properly remediated, poses a threat to the environment and human health by carrying significant loads of nutrients and pathogens. These contaminants pollute rivers, lakes and natural reservoirs where they cause eutrophication and pathogen-mediated diseases. However, the high nutrient content of WW makes it an ideal environment for remediation with microalgae that require high nutrient concentrations for growth and are not susceptible to toxins and pathogens. Given that an appropriate algal strain is used for remediation, the incurred biomass can be refined for the production of biofuel. Four microalgal species (Chlamydomonas reinhardtii, Chlorella sp., Parachlorella kessleri-I and Nannochloropsis gaditana) were screened for efficient phycoremediation of municipal WW and potential use for biodiesel production. Among the four strains tested, P. kessleri-I showed the highest growth rate and biomass production in 100% WW. It efficiently removed all major nutrients with a removal rate of up to 98% for phosphate after ten days of growth in 100% municipal WW collected from Delhi. The growth of P. kessleri-I in WW resulted in a 50% increase of biomass and a 115% increase of lipid content in comparison to growth in control media. The FAME and fuel properties of lipids isolated from cells grown in WW complied with international standards. The present study provides evidence that the green alga P. kessleri-I effectively remediates municipal WW and can be used to produce biodiesel

Innovative financing models for low carbon transitions: Exploring the case for revolving funds for domestic energy efficiency programmes

The IEA has estimated that over the next four decades US$31 trillion will be required to promote energy efficiency in buildings. However, the opportunities to make such investments are often constrained, particularly in contexts of austerity. We consider the potential of revolving funds as an innovative financing mechanism that could reduce investment requirements and enhance investment impacts by recovering and reinvesting some of the savings generated by early investments. Such funds have been created in various contexts, but there has never been a formal academic evaluation of their potential to contribute to low carbon transitions. To address this, we propose a generic revolving fund model and apply it using data on the costs and benefits of domestic sector retrofit in the UK. We find that a revolving fund could reduce the costs of domestic sector retrofit in the UK by 26%, or £9 billion, whilst also making such a scheme cost-neutral, albeit with significant up-front investments that would only pay for themselves over an extended period of time. We conclude that revolving funds could enable countries with limited resources to invest more heavily and more effectively in low carbon development, even in contexts of austerity

Differential maturation and subcellular localization of severe acute respiratory syndrome coronavirus surface proteins S, M and E

Post-translational modifications and correct subcellular localization of viral structural proteins are prerequisites for assembly and budding of enveloped viruses. Coronaviruses, like the severe acute respiratory syndrome-associated virus (SARS-CoV), bud from the endoplasmic reticulum-Golgi intermediate compartment. In this study, the subcellular distribution and maturation of SARS-CoV surface proteins S, M and E were analysed by using C-terminally tagged proteins. As early as 30 min post-entry into the endoplasmic reticulum, high-mannosylated S assembles into trimers prior to acquisition of complex N-glycans in the Golgi. Like S, M acquires high-mannose N-glycans that are subsequently modified into complex N-glycans in the Golgi. The N-glycosylation profile and the absence of O-glycosylation on M protein relate SARS-CoV to the previously described group 1 and 3 coronaviruses. Immunofluorescence analysis shows that S is detected in several compartments along the secretory pathway from the endoplasmic reticulum to the plasma membrane while M predominantly localizes in the Golgi, where it accumulates, and in trafficking vesicles. The E protein is not glycosylated. Pulse-chase labelling and confocal microscopy in the presence of protein translation inhibitor cycloheximide revealed that the E protein has a short half-life of 30 min. E protein is found in bright perinuclear patches colocalizing with endoplasmic reticulum markers. In conclusion, SARS-CoV surface proteins S, M and E show differential subcellular localizations when expressed alone suggesting that additional cellular or viral factors might be required for coordinated trafficking to the virus assembly site in the endoplasmic reticulum-Golgi intermediate compartment. © 2005 SGM.postprin

The effect of the introduction of Nile tilapia ( Oreochromis niloticus , L.) on small indigenous fish species (mola, Amblypharyngodon mola , Hamilton; chela, Chela cachius , Hamilton; punti, Puntius sophore , Hamilton)

This is the first controlled experiment to quantify the effect of introduced tilapia on indigenous species. This experiment was conducted in small earthen ponds (100 m 2 ) to assess the impact of mixed-sex or all-male Nile tilapia ( Oreochromis niloticus ) on small indigenous species (SIS) commonly found in south Asia, mola ( Amblypharyngodon mola ), chela ( Chela cachius ) and punti ( Puntius sophore ). Ponds were fertilized, then stocked with 0.56 fish m −2 of water surface area in the mixed-sex and all-male tilapia treatments and 0.42 fish m −2 in the treatment without tilapia. No additional nutritional inputs were applied after stocking. Treatments were: mixed-sex tilapia with SIS, mono-sex male tilapia with SIS and SIS without tilapia (control). All treatments were stocked with 14 fish per species. All species reproduced during the 21-month culture duration. The number of recruits varied by species, Tilapia reproduced in greater numbers than SIS. Tilapia numbers at harvest were the highest (451 ± 25/100 m 2 ) in the mixed-sex treatment compared with mola (221 ± 22/100 m 2 ), chela (94 ± 8/100 m 2 ) and punti (100 ± 7/100 m 2 ). The number of mola was higher (399 ± 33/100 m 2 ) in the all-male tilapia treatment. There was reduction in the number of mola and chela in the treatment containing mixed-sex tilapia. Gut content analysis combined with water sampling revealed that all fish species fed selectively. Significant interspecies dietary overlap was found between Nile tilapia and SIS and among SIS. Thus, there is potential for tilapia to compete with indigenous fish species when space and other resources are limiting, but a longer duration study with varying level of management is needed to determine how successfully tilapia competes with locally adapted SIS.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/79201/1/j.1365-2109.2009.02372.x.pd
