This article discusses challenges that artificial photosynthetic (AP) systems will face when entering and competing in a global market characterized by established fossil fuel technology. It provides a perspective on the neoliberal principles underpinning much policy entrenching such environmentally destructive technology and outlines how competition law could aid overcoming these hurdles for AP development. In particular, it critiques the potential for competition law to promote a global AP initiative with greater emphasis on atmospheric carbon dioxide and nitrogen fixation (as well as solar-driven water splitting) to produce an equitable, globally distributed source of human food, fertilizer and biosphere sustainability, as well as hydrogen-based fuel. Some relevant strategies of competition law evaluated in this context include greater citizen–consumer involvement in shaping market values, legal requirements to factor services from the natural environment (i.e. provision of clean air, water, soil pollution degradation) into corporate costs, reform of corporate taxation and requirements to balance maximization of shareholder profit with contribution to a nominated public good, a global financial transactions tax, as well as prohibiting horizontal cartels, vertical agreements and unilateral misuse of market power.

Frequent changes on the global market are making it difficult to determine future tourist trends. Competition among foreign hotel chains, national tourism enterprises and family businesses is dynamising the market in response to increasingly discerning tourist needs. Hotel and tourism enterprises need to actively manage changes in creating new competitive advantages. Business reengineering, changing the business philosophy and creating a new generation of managers are preconditions needed to break away from the remnants of the former system and to bridge the gap between excellent opporunities and confined reality. To adapt to the system of new market values, companies must apply modern business determinants and innovative development strategies.

Abstract Biobased polymers are sustainable polymers produced from renewable resources such as biomass feedstocks instead of the industrial fossil resources such as petroleum and natural gases. This trend helps in creating an environmentally friendly chemical processing that is characterized by low carbon footprint emission to the globe which in turn will limit the increase of the atmospheric carbon dioxide concentration even after their incineration. Synthesis of polymeric materials from biobased resources also solves the problem of polymer waste recycling. This chapter covers a basic background on the origin and importance of biobased polyamides, different synthetic routes of their starting monomeric materials obtained from biomass feedstocks, and a brief summary of the physical and chemical properties and applications of some common aliphatic, semiaromatic and fully aromatic polyamides. This chapter ends with a recent published data on the growth of the global market of biobased polyamides to emphasize on the economic importance of this manufacturing trend.

The atmospheric testing of nuclear weapons during the 1950s and early 1960s produced large amounts of radiocarbon. This 14C bomb pulse provides useful age information in numerous scientific fields, e.g. in geosciences and environmental sciences. Bomb-pulse dating can also be used to date human material (e.g. in forensics and medical science). Bomb-pulse dating relies on precise measurements of the declining 14C concentration in atmospheric carbon dioxide collected at clean-air sites. However, local variations in the 14C specific activity of air and foodstuffs occur, which are caused by natural processes as well as by various human activities. As 14C enters the human body mainly through the diet, variations of 14C concentration in foodstuffs need to be considered. The marine component of the diet is believed to be of particular importance due to the non-equilibrium in 14C specific activity between the atmosphere and aquatic reservoirs during the bomb pulse. This article reviews the 14C concentration in marine foodstuffs during the bomb-pulse era, and models how the marine component in one's diet can affect the precision of bomb-pulse dating of human material.
