The increasing accumulation of synthetic plastic waste in oceans and landfills, along with the depletion of non-renewable fossil-based resources, has sparked environmental concerns and prompted the search for environmentally friendly alternatives. Biodegradable plastics derived from lignocellulosic materials are emerging as substitutes for synthetic plastics, offering significant potential to reduce landfill stress and minimise environmental impacts. This study highlights a sustainable and cost-effective solution by utilising agricultural residues and invasive plant materials as carbon substrates for the production of biopolymers, particularly polyhydroxybutyrate (PHB), through microbiological processes. Locally sourced residual materials were preferred to reduce transportation costs and ensure accessibility. The selection of suitable residue streams was based on various criteria, including strength properties, cellulose content, low ash and lignin content, affordability, non-toxicity, biocompatibility, shelf-life, mechanical and physical properties, short maturation period, antibacterial properties and compatibility with global food security. Life cycle assessments confirm that PHB dramatically lowers CO₂ emissions compared to traditional plastics, while the growing use of lignocellulosic biomass in biopolymeric applications offers renewable and readily available resources. Governments worldwide are increasingly inclined to develop comprehensive bioeconomy policies and specialised bioplastics initiatives, driven by customer acceptability and the rising demand for environmentally friendly solutions. The implications of climate change, price volatility in fossil materials, and the imperative to reduce dependence on fossil resources further contribute to the desirability of biopolymers. The study involves fermentation, turbidity measurements, extraction and purification of PHB, and the manufacturing and testing of composite biopolymers using various physical, mechanical and chemical tests.

I argue that the official story about the collapses of the Twin Towers and building 7 of the World Trade Center, according to which the collapses were caused by fire – combined, in the case of the Twin Towers, with the effects of the airplane impacts – cannot be true, for two major reasons. One reason is that fire has never, except allegedly three times on 9/11, caused the total collapse of steel-frame high-rise buildings. All (other) such collapses have been produced by the use of explosives in the procedure known as “controlled demolition.” The other major problem is that the collapses of all three buildings had at least 11 features that would be expected if, and only if, explosives had been used.

I also show the importance of the recently released of 9/11 Oral Histories recorded by the New York Fire Department. With regard to the Twin Towers, many of the firefighters and medical workers said they observed multiple explosions and other phenomena indicative of controlled demolition. With regard to building 7, many testimonies point to widespread foreknowledge that the building was going to collapse, and some of the testimonies contradict the official story that this anticipation of the building's collapse was based on objective indications. These testimonies further strengthen the already virtually conclusive case that all three buildings were brought down by explosives.

I conclude by calling on the New York Times, which got the 9/11 Oral Histories released, now to complete the task of revealing the truth about 9/11.

There is no industry in the world where a crisis caused by terrorism has such a strong impact as in tourism. Providing security for visitors before and during a trip can be a critical success factor for the competitiveness of a particular destination or organization or for business tourism when tourists consider multiple alternatives. Information about political instability, violence, crime or terrorist attacks could cause a substitution effect by tourists. International terrorism and tourism share some characteristics, as both cross national borders, involve citizens from different countries and use the new travel and communications technologies. In recent decades, terrorism organizations have been using tourism targets to gain global visibility. Based on a broad analysis of literature and data, the main goal of this research is to update the work of Seabra (2019) and help to analyse the main connections between terrorism and tourism, specifically by presenting the main terrorist events targeting tourism activity and destinations in the last 35 years and their main consequences for tourism industry.

This chapter presents several approaches for identifying and dating the speculative bubble on real estate market. Using the real estate price index (IPAI), statistical and structural approaches were combined in order to detect the existence of a bubble on the Moroccan real estate market. The results obtained affirm that the Moroccan real estate market experienced a speculative bubble during the period 2006–2008 explained mainly by the boom of credit during the same period. The use of the Markov switching model affirmed that the speculative bubble on Morocco is cyclic and consequently corroborates the critic formulated by Evans (1991) concerning the traditional approaches for the detection of financial bubbles. Thus, the analysis of the series of the bubble, extracted using the Kalman filter, affirms the existence of two regimes, namely an explosive regime and a normal regime. The first regime describes the periods of explosion of the bubble and lasts for about 9 quarters, while the second, lasting for 14 quarters, describes the periods of return to the average cycle.

In the cold war era, perhaps there were no greater heroes of the Soviet Union than the as many as 700,000 firefighters, workers, and military personnel who fought the blazing fires at the Chernobyl nuclear reactor that burned out of control for months until smothered by a makeshift concrete structure, called the “sarcophagus” built to contain radioactive releases. Whether this sarcophagus will last as long as the Egyptian monuments, its name evokes has been a matter of grave continuing concern. And it is doubtful that its symbolism as a lasting evidence of 20th century life will be equally appreciated through the ages. But in April 26, 1986, northern Europe had been placed in dire peril by the catastrophic accident in the number 4 reactor at Chernobyl. Smoke pouring from the fires lofted high in the sky to carry radioactive contaminants eventually across the Northern Hemisphere. Some 100 million curies of radiation were released within 10 days of the initial explosion, comprising the word's worst civilian radiation release (Lawrence Livermore, 1999). And, the reactor threatened to unleash a nuclear explosion that would have dwarfed the effects of what already was the world's worst nuclear accident. The situation demanded extreme sacrifice (see also Zykova, this volume).

Contemporary Anglo-American economics, which I admire, faces two major obstacles. First, in its drive at least since Milton Freedman to be a positive science free of normative issues, it ignores its own current intellectual foundations buried at the heart of its analysis of the “advantages of trade”: Fairness. Second, the major driver of economic growth in the past 50,000 years has been the explosion of goods and production capacities from perhaps 1,000 to 10,000 long ago, to perhaps 10 billion goods and production capacities today. Economics, lacking a theory for this explosion, deals with this explosion by ignoring it and treating it as “exogenous” to its theory.

The “Edgeworth Box” carries the heart of advantages of trade, demonstrating for properly curved isoutility curves a region where you and I are better-off trading some of my apples for some of your pears. The ratio of these in trade constitutes price. But spanning the region of advantages of trade is the famous CONTRACT CURVE, where we have exhausted all the advantages of trade. Different points on the curve correspond to different prices. But the Contract Curve is Pareto Optimal, motion on the curve can only make one of us better-off at the expense of the other. Critically, economics has NO THEORY for where we end up on the Contract Curve. Nor, since different points on the curve correspond to different prices, can PRICE settle the issue.

Using the Ultimatum Game I will show that FAIRNESS typically drives where we settle on the Contract Curve, as long as we do not have to trade with one another. Thus ethics enters economics at its foundation, yet cannot be mathematized, so is ignored in Freedman’s name of a positive science.

Perhaps more important, unlike physics, no laws entail the evolution of either the biosphere or the “econosphere.” There are no laws of motion whose integration would entail that evolution. Lacking an entailing theory of the growth of the economy in diversity, often of new goods and production capacities, economists ignore the most important feature of economic growth, wrongly treating it as “exogenous.”

The failures above are likely to play major roles in the lapse to mere greed in our major financial institutions, and in our inadequate capacities to help drive growth in much of the poverty-struck world.

This study investigated the potential for the development of dark tourism in Lebanon, a destination that has suffered multiple crises in recent years including conflicts and the world's largest non-nuclear explosion, which devastated a large section the country's capital city, Beirut. Research was carried out using desk audit, key informant interviews and archival research, which identified 21 potential dark tourism sites that could be incorporated into a new dark tourism product as part of the recovery of Lebanon as a tourism destination. Of these 21 sites, the majority were found in Beirut, suggesting that an urban dark tourism product may be the most suitable product to develop as the country emerges from crises. However, a number of barriers would need to be overcome in order for dark tourism to contribute to a form of phoenix tourism in the country, including the engagement of diverse stakeholders, the security of international tourists in the destination, and the ability of the public sector to invest in destination marketing in the post-crisis period.

Non-governmental organisations (NGOs) fulfil a vital role in society, filling the gap often left between civic responsibility undertaken through an agency of the government and personal responsibility often undertaken through the family. Indeed the modern streamlined state very often deliberately relies on such NGOs to undertake responsibilities previously undertaken by the state, such as health, welfare and educational roles, which can no longer be undertaken due to the twisted logic of privatisation. To fill the gap, states often rely on NGOs and provide funding accordingly – a state obligation undertaken by proxy. The role and significance of NGOs has therefore risen accordingly; commensurate with this we have seen an explosion in the number of NGOs and a concomitant explosion in the spheres of influence of such organisations and in the roles that they claim for themselves.

Introduction: With the proliferation and amalgamation of technology and the emergence of artificial intelligence and the internet of things, society is now facing a rapid explosion in big data. However, this explosion needs to be handled with care. Ethically managing big data is of great importance. If left unmanageable, it can create a bubble of data waste and not help society achieve human well-being, sustainable economic growth, and development.

Purpose: This chapter aims to understand different perspectives of big data. One philosophy of big data is defined by its volume and versatility, with an annual increase of 40% per annum. The other view represents its capability in dealing with multiple global issues fuelling innovation. This chapter will also offer insight into various ways to deal with societal problems, provide solutions to achieve economic growth, and aid vulnerable sections via sustainable development goals (SDGs).

Methodology: This chapter attempts to lay out a review of literature related to big data. It examines the implication that the big data pool potentially influences ideas and policies to achieve SDGs. Also, different techniques associated with collecting big data and an assortment of significant data sources are analysed in the context of achieving sustainable economic development and growth.

Findings: This chapter presents a list of challenges linked with big data analytics in governance and achievement of SDG. Different ways to deal with the challenges in using big data will also be addressed.
