Abstract

Purpose – The purpose of this research is to synthesize modified thermoplastic sago starch (TPS) through in-situ mechanism by reacting sago starch with diphenylmethanediisocyanate (MDI) and castor oil simultaneously, resulting in a more homogenous and finer-sized polyurethane prepolymer (PUP).

Design/Methodology/Approach – The methods used were Thermal Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) for thermal characterization and stability of PUP, modified TPS non-extracted and extracted with toluene and water.

Findings – TGA test results presented shows that PUP begins to decompose thermally at a temperature of 300–500 °C. Weight loss occurs rapidly between these temperatures and is completely discharged at a temperature of 500°C, which is called weight loss transition.

Research Limitations/Implications – When extracted with toluene and a water solvent, the melting point and latent heat of fusion slightly decreased; however, it is still higher than the original value of sago. In terms of thermal stability, modified TPS decomposes and loses weight at 150–200 °C in small quantities, continues with weight loss rapidly, and is completely discharged at 500°C. The thermal stability is considered high; thus, modified TPS application can be varied.

Practical Implications – DSC analysis and TGA shows that modified TPS has good thermal characteristics and thermal stability. Modified TPS has a melting point of 104.69°C, and the latent heat of fusion (ΔH) is 234.27 J/g. This value is close to the PUP melting point and latent heat of fusion, which reveals the formation of cross-link between the starch and PUP.

Abstract

During the great post–World War II economic expansion, modernization theorists held that the new American capitalism balanced mass production and mass consumption, meshed profitability with labor's interests, and ended class conflict. They thought that Keynesian policies insured a near full-employment, low-inflation, continuous growth economy. They viewed the United States as the “new lead society,” eliminating industrial capitalism's backward features and progressing toward modernity's penultimate “postindustrial” stage.7 Many Americans believed that the ideal of “consumer freedom,” forged early in the century, had been widely realized and epitomized American democracy's superiority to communism.8 However, critics held that the new capitalism did not solve all of classical capitalism's problems (e.g., poverty) and that much increased consumption generated new types of cultural and political problems. John Kenneth Galbraith argued that mainstream economists assumed that human nature dictates an unlimited “urgency of wants,” naturalizing ever increasing production and consumption and precluding the distinction of goods required to meet basic needs from those that stoke wasteful, destructive appetites. In his view, mainstream economists’ individualistic, acquisitive presuppositions crown consumers sovereign and obscure cultural forces, especially advertising, that generate and channel desire and elevate possessions and consumption into the prime measures of self-worth. Galbraith held that production's “paramount position” and related “imperatives of consumer demand” create dependence on economic growth and generate new imbalances and insecurities.9 Harsher critics held that the consumer culture blinded middle-class Americans to injustice, despotic bureaucracy, and drudge work (e.g., Mills, 1961; Marcuse, 1964). But even these radical critics implied that postwar capitalism unlocked the secret of sustained economic growth.

Abstract

In 2001, the Intergovernmental Panel on Climate Change's Third Assessment Report revealed an important increase in the level of consensus concerning the reality of human-caused climate warming. The scientific basis for global warming has thus been sufficiently established to enable meaningful planning of appropriate policy responses to address global warming. As a result, the world's policy makers, governments, industries, energy producers/planners, and individuals from many other walks of life have increased their attention toward finding acceptable solutions to the challenge of global warming. This laudable increase in worldwide attention to this global-scale challenge has not, however, led to a heightened optimism that the required substantial reductions in carbon dioxide (CO2) emissions deemed necessary to stabilize the global climate can be achieved anytime soon. This fact is due in large part to several fundamental aspects of the climate system that interact to ensure that climate change is a phenomenon that will emerge over extensive timescales.

Although most of the warming observed during the 20th century is attributed to increased greenhouse gas concentrations, because of the high heat capacity of the world's oceans, further warming will lag added greenhouse gas concentrations by decades to centuries. Thus, today's enhanced atmospheric CO2 concentrations have already “wired in” a certain amount of future warming in the climate system, independent of human actions. Furthermore, as atmospheric CO2 concentrations increase, the world's natural CO2 “sinks” will begin to saturate, diminishing their ability to remove CO2 from the atmosphere. Future warming will also eventually cause melting of the Greenland and Antarctic ice sheets, which will contribute substantially to sea level rise, but only over hundreds to thousands of years. As a result, current generations have, in effect, decided to make future generations pay most of the direct and indirect costs of this major global problem. The longer the delay in reducing CO2 and other greenhouse gas emissions, the greater the burden of climate change will be for future life on earth.

Collectively, these phenomena comprise a “global warming dilemma.” On the one hand, the current level of global warming to date appears to be comparatively benign, about 0.6°C. This seemingly small warming to date has thus hardly been sufficient to spur the world to pursue aggressive CO2 emissions reduction policies. On the other hand, the decision to delay global emissions reductions in the absence of a current crisis is essentially a commitment to accept large levels of climate warming and sea level rise for many centuries. This dilemma is a difficult obstacle for policy makers to overcome, although better education of policy makers regarding the long-term consequences of climate change may assist in policy development.

The policy challenge is further exacerbated by factors that lie outside the realm of science. There are a host of values conflicts that conspire to prevent meaningful preventative actions on the global scale. These values conflicts are deeply rooted in our very globally diverse lifestyles and our national, cultural, religious, political, economic, environmental, and personal belief systems. This vast diversity of values and priorities inevitably leads to equally diverse opinions on who or what should pay for preventing or experiencing climate change, how much they should pay, when, and in what form. Ultimately, the challenge to all is to determine the extent to which we will be able to contribute to limiting the magnitude of this problem so as to preserve the quality of life for many future generations of life on earth.

Abstract

Global temperature has risen by 1°C since 1900, while since the 1990s the Arctic has recently experienced an accelerated warming of about double the average rate of global warming. Nearly all climate scientists agree that the main cause of this temperature rise is ever-increasing accumulations of ‘greenhouse gases’, especially carbon dioxide and methane, within our atmosphere. Sea level rise could easily exceed one metre this century under ‘business as usual’. However, global warming is not just about rising temperatures, melting ice and rising sea levels, but it also affects the frequency and severity of many extreme weather events. Planetary warming is not a uniform process, can spring surprises in regional climate change and is probably linked with the tendency for Northern Hemisphere mid-latitudes to have more extreme (variously hot/cold/dry/wet) weather, especially during the recent period of rapid Arctic warming. There is overwhelming scientific evidence that human activity through enhanced greenhouse gas emissions is largely responsible for recent climate change and accompanying extreme weather, and we are already clearly seeing these changes. However, it is equally evident that, although initial remedial steps are being taken, finding an adequate solution will not be easy unless much larger changes are made to the way in which we all live. Limiting global warming to 1.5°C above pre-industrial temperatures would require global carbon dioxide emissions to decrease by approximately 40–60% by 2030 relative to 2010 levels. This can only be achieved through a collective solution that fully involves diverse communities, among them religious stakeholders.

Abstract

Recent research in cognitive and social psychology finds that individual change is more emotional than rational. Further evidence suggests that the contagious power of emotions explains how groups may overcome obstacles and behave in unified ways. We offer a neuropsychological model of emotion-driven change in organizations that explains these findings and predicts conditions in which contagion effects will be successful in facilitating rapid change. Our model posits that emotive precursors to conscious action enable goal alignment and overcome cognitive resource limitations necessary to sustain organizational change over time. Our model adapts the findings from social and cognitive neuroscience to bring new insights into the mental mechanisms underlying the change process. The chapter concludes with tentative suggestions for developing new methods for research and practice that improve our predictive capability for creating rapid large-scale organizational change.

Abstract

In the southern hemisphere, the Antarctic continent is also experiencing a net loss in ice from the extensive glaciers and ice sheets that cover it. However, the connection between changes in Antarctic ice sheets and the global warming trend are much more uncertain than in the Arctic. The complex of changes in the Antarctic climate and the ice sheets are described in a later section of this chapter.

Abstract

Purpose – This purpose of the research is to investigate the process of manufacturing LDPE recycle thermoplastic composites with reinforcement oil palm empty fruit bunch (OPEFB) biomass microfillers.

Design/Methodology/Approach – Methods of physical and chemical modification of OPEFB fibers into the LDPE matrix and the addition of some compatibilizer such as MAPE and xylene process through melt blending can improve mechanical properties, electrical properties, biodegradability, and improve the morphology of composites.

Research Limitations/Implications – These composites are prepared by the following matrix ratio: filler (70:30)% and filler size (63, 75, 90, and 106) μm. The LDPE plastic is crushed to a size of 0.5–1 cm, then pressed with hot press free heating for 5 min and with a pressure of 10 min at 145 °C. Based on the characterization obtained, the tensile strength and the high impact on the use of 106 μm filler is 13.86 MPa and 3,542.6 J/m2, and thermal stability indicates the degradation temperature (T0) 497.83 °C. FT-IR analysis shows the presence of functional groups of cellulose and lignin molecules derived from TKKS collected in the composite.

Practical Implications – Based on the characterization obtained, this composite can be applied as furniture material and vehicle dashboard.

Originality/Value – Composites obtained from recycle of LDPPE plastics waste has some advantages such as good compatibility and high tensile strength. This composite used the OPEFB filler whose size is in micrometer, and so this product is different from other products.

Abstract

Purpose

The anti-apartheid movement represented a cornerstone for socially responsible investors in the 1970s and 1980s driven by the willingness to promote lasting social change. What happened next in terms of socially responsible investing (SRI) in the free South Africa? This chapter explores the local development of SRI in South Africa post-apartheid.

Design/methodology/approach

An in-depth literature review combined with a content analysis 73 SRI funds’ investment mandates were undertaken to investigate the local development of SRI in South Africa over the period 1992–2012.

Findings

Mechanisms of local divergence and global convergence have both shaped the phenomenon of SRI in South Africa. SRI in South Africa represents a melting-pot of societal values anchored in a local developmental and transformative political vision, some local and global Islamic religious values, and worldwide SRI and CSR homogenisation trends.

Originality/value

This chapter is the first attempt to outline the mechanisms of local divergence and global convergence that have moulded SRI in a democratic South Africa.

Abstract

The melting pot of trade and commerce in present day Zambia dates to the interactions between the peoples who inhabited the territory, their new migratory neighbours fleeing regional conflicts and consequent interactions with European explorers attempting to penetrate the interior region of south central Africa. Today, Zambia is a blend of 73 multi-ethnic groups that have inter-married, coexisted and crossed paths with many central, eastern and southern African societies and empires in the name of trade, expansion and exploration. The Zambian chapter explores what practices were part of their societal structures and what has survived the fusion of migrants whether intra-continental or beyond. This chapter also presents the subsequent post-independence complex society under the Zambian identity and the author reflects on how Africans can manage affairs responsibly.

Abstract

The authors analyze how conflicting institutional demands become deployed in organizational storytelling in the context of wildlife documentaries. Documentary producers increasingly feel the pressure to entertain the audience, while simultaneously addressing serious environmental issues. Using a mixed-method analysis of BBC wildlife documentaries produced between 2009 and 2017, the authors identify two narrative strategies, alternation and amplification, to balance demands for entertainment and environmental conservation. Alternation switches entertaining and serious content to offset conservation concerns, while amplification uses entertainment to accentuate conservation. Emotions play a significant role in both ways of storytelling. The findings of this chapter contribute to the literatures on institutional microfoundations, storytelling, and emotions.
