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.

Since the early modern age, the debt of the State was a constant source for concern to the Spanish governments. Episodes of defaults caused by enormous expenditure to keep the Empire slowly faded out until a certain reorganization of public finance was attained in the central decades of the nineteenth century. The core idea that finance ministers and economists, in general, had at that time was to balance the public budget controlling expenses, in order to handle the problem of public debt. However, alternative views on government finance existed. Focusing on a crucial period for the consolidation of Spanish liberal regime and its public finance, this chapter shows that, among a predominant concern for reducing public expenditure as the best way to stabilize the economy and promote economic growth, the character of Luis María Pastor emerges to support government expansionary policies financed with credit. Far from fearing deficit, Pastor, one of the leaders of the Spanish liberal school of economic thought, believed that investment in infrastructures financed through debt was the key to economic growth. Through a multiplicative effect, a program of public investment would enhance economic growth, eventually solving the long-term insufficiency of Spanish finance. This gives evidence that ideas on public finance of classical liberal economists were far from uniform, contributing to a more precise view on the body of doctrines of this school.

The author looks at how advertising aimed at cisgender men has shifted over the last two decades, moving from standard representations of hegemonic forms of masculinity to the adoption of the language and style of “postfeminist authenticity.” Drawing on a range of insights from across the social sciences and using the examples of three popular grooming products, Axe, Gillette, and Dollar Shave Club, the author critically examines the manner in which these new campaigns emphasize individual self-improvement and consumption choices as a means to solving the problems generated “by traditional, supposedly inauthentic, expressions of masculinity.”

The implementation of digital technologies shifts the way firms manage their supply chains with the objective of obtaining closer relationships with their partners. The main improvement is that each partner can access others’ information in real time. This gives rise to the concept of digital supply chain where interconnectedness is the link. Applying digital technologies has reported innumerable benefits, and despite the fact that only a few firms make full use of them, they have become a very promising future trend.

This study aims to review the literature on supply chain and digital technologies in relation to the different benefits that each of these technologies provides in the different stages of the supply chain. Eventually, this will provide a guide to determine and select those technologies that best suit the needs of a firm according to their characteristics within the supply chain.

The key purpose of the current study is investigating the direct impact of information technology (IT) assimilations, flexible IT infrastructure, and supply chain competencies (supply side, demand side) on the supply chain performance of manufacturing firms. Meanwhile, the study has also estimated the mediating role of supply chain agility (SCA). Among 360 selected respondents for the underlying research, only 267 respondents have responded well and returned them back, thereby indicating 74% response rate for the survey. For the inferential analysis, the Partial Least Square Structural Equation Modeling was performed in Smart PLS 3.0. In context to this study, process compliance is the adherence and the execution of supply chain processes, including the processes related to distribution and production of management processes. On the basis of this theoretical background, the demand and supply-side competence are considered as the firms’ internal aspects. As a dynamic capability, the SCA enables firms to influence and respond to the firm’s external environment. Thus, the presence of such competencies allows to react against market developments. The resource-based view theory supports this argument, and states that competencies is an effective resource for developing dynamic capabilities.

Since 2012, with the Growth Decree 2.0, the Italian Government has been engaged in promoting the establishment and the growth of new innovative startups with a high technological value. The general objective of the policy is to promote sustainable growth, technological advancement and innovation. In the Decree framework, startups have to own an innovative character that is identified by at least one of the following three criteria: investments in research and development, qualified workforce, holding patents or registered software. Such three characteristics can be considered as innovation inputs able to create the conditions for a competitive advantage and greater economic performance. The research objective is to analyze how innovation inputs in innovative startups affect their economic performance. Each input factor can have a different impact on the company profitability. To this end, we apply the methodology SMAA for strategic management analysis and assessment (or SMAA-S) to detect the relation between innovation and profitability in Italian startups.

Raphael Bar-El is an economist, Professor at Ben-Gurion University of the Negev and Chair of the Department of Public Policy and Administration. His main areas of interest are: economic growth, regional development, economic cooperation in the Middle East, small towns. In the last few years, he has worked with the State Government of Ceara (Brazil) on policy measures for the alleviation of poverty through economic regional development. He was the Director of the National Economic Planning Authority, at the Ministry of Economy and Planning. He was also a member of the Joint (Jordan–Israel–US) Steering Committee for the Integrated Development of the Jordan Rift Valley (JRV). He was in charge of the Economic Development Plan within the team of the long-term Master Plan for Israel. In 1996 and 1997, he was a member of the project headed by Michael Porter on Building Regional Competitive Advantage in the Middle East. Until 1993 he was a researcher and planner, the Director of Research, and finally the Director General of the Development Study Center (DSC), Rehovot, Israel. He has acquired extensive experience in regional development research and planning, in Israeli regions, as well as in regions in the developing world.

We present a specific mathematical model for predicting allocative behaviors in the context of reward expectations theory. We test the goodness of fit of the model to data from two empirical studies and demonstrate that it fits quite well. We also suggest alternative research uses for the model.
