Many problems occur when assigning tasks to work centres, especially in determining the required number of workstations for line balancing which requires a minimum theoretical number of workstations. The most common problem is bottleneck. In this paper, a method is proposed to solve floating tasks problem in single-model line when the actual required number of workstations exceeds the minimum theoretical number, and the standard time of the floating task (work center) exceeds the cycle time. The floating task will represent a critical bottleneck activity in line. The proposed method depends on minimizing the standard time of critical bottleneck and non-critical activities by a minimum free-floating time depends on the average of slack times of the non-critical activities, and it will increase the line efficiency from (77%) to (88%), and balance delay is minimized from (23%) to (12%).

The coronavirus disease of 2019 (COVID-19) generated a crisis; however, it also gave us an opportunity to imagine the future and build a better world. Moreover, as we are convinced of the importance of understanding the lessons of history when facing both current and future challenges, this chapter seeks to present a concise overview of global crises since the end of the nineteenth century and to show crises for which we ignored the warning signs and wakeup calls, the consequences of said crises and how we managed to recover and thrive in several cases. Ultimately, we seek to justify the capacity of humanity to build a sustainable future – ideally, a regenerative future.

The world currency is endowed with two inherent contradictions, namely, the general contradiction of all currencies and the special contradiction between the quality and quantity of the world currency. The paper aims to discuss these issues.

In the wake of the Second World War, the USA, with its strong economic and military strength, established an international monetary system centered on the US dollar (USD). This gave USD the status of “world currency” and bounded it to the US imperialist hegemony with mutual integration and interaction, making it possible for USD capital to conduct international exploitation and wealth plundering extensively around the world.

The contradiction between the capital logic and the power logic, which is inherent in capital accumulation models of the new imperialism, also indicates the inevitable decline of USD.

This constitutes an important feature of the new imperialism. However, as a sovereign currency, USD has inextricable and inherent contradictions while exercising its function as the world currency.

AN interesting feature of the Lockheed Sirius used by Colonel Lindbergh on his flight via Alaska, the Behring Straits and the Aleutian and Keurile Islands to Japan, is the twin‐float attachment fitted to the machine to convert it into a seaplane by the Edo Aircraft Corporation of Long Island, New York.

The purpose of this paper is to present a single-precision floating-point multiplier where a low-power operation is attained through the reduction of switching activity. A floating-point multiplier is the basic building block for many applications such as digital signal processing (DSP) processors and multimedia applications involving a large dynamic range.

A floating-point multiplier was implemented in asynchronous logic such as multi-threshold null conventional logic and the proposed multi-threshold dual spacer dual rail delay insensitive logic (MTD³L). The proposed logic deals with high performance and energy efficiency.

The Institute of Electrical and Electronics Engineering (IEEE) has provided a standard to define the floating-point representation, which is known as the IEEE 754 standard. Rounding has not been implemented because it is not suitable for high-precision applications.

The performance aspects of the proposed asynchronous MTD³L floating-point multiplier are obtained using a Mentor Graphics tool and are compared with those of the existing asynchronous logic.

At present, the scale of China's floating population has reached 376 million people. Compared with the local inhabitants, the poverty problem of the floating population is more complex, and this problem should also attract the attention of all sectors of society. This paper aims to measure and analyze the multidimensional poverty of the floating population in China.

The data used in this paper are the data of the China Migrants Dynamic Survey (CMDS) in China. This survey is a large-scale national migratory population sampling survey organized by the China National Health Commission, covering 31 provinces (autonomous regions and cities) and other autonomous regions. This paper uses the dynamic monitoring and Alkire and Foster (A-F) method to study the multidimensional poverty problem of the floating population.

This study finds that income poverty is no longer the main type of poverty faced by the floating population. The multidimensional poverty of the floating population mainly occurs in the social security and education dimensions, of which social security has become the most severe poverty dimension of the floating population. From the perspective of group differences, compared with the floating population in urban areas, the multidimensional poverty of migrant workers is more serious. However, the poverty of migrant workers is mainly concentrated in one-dimensional poverty and two-dimensional poverty.

In the future, the authors should focus on the social security of the floating population in the place of influx and the education of the floating population.

Through the review of the existing literature, the authors find that the current research on the multidimensional poverty of the floating population is mainly concentrated on the migrant worker groups that move from rural areas to urban areas. However, insufficient attention is paid to the urban floating population groups moving between cities.

The purpose of this paper is to examine the role of neoliberalism and the accreditation of educational leadership programs in one Gulf Cooperation Council (GCC) country by contextualizing the accreditation process and closely examining the Educational Leadership Constituent Council (ELCC) standards used by NCATE, now CAEP, to accredit educational leadership programs in the GCC. By using Habermas’ knowledge constitutive interests (KCIs) and evoking notions of floating signifiers, the paper develops an understanding of the use of Western-developed standards in a country that is different than the one in which these standards were conceived and how the discourse of accreditation standards shapes understandings and meanings of educational leadership.

A critical discourse analysis of the ELCC standards is conducted using a two-prong strategy that applies Habermas’ KCIs and evoking the notions of floating signifiers as a theoretical framework.

Understanding that knowledge is bounded by cultural circumstances, findings indicate that the ELCC standards contain all three KCIs, and various floating signifiers are embedded within the ELCC discourse that are problematic in a culture that is vastly different than the one in which these standards were conceived.

There are a few, if any, studies that have examined neoliberalism and accreditation in a GCC country. In particular, there are no studies that have examined the ELCC standards being used outside the USA. The research provides educators with an insight into the different forms of knowledge and understanding of the surplus of meaning of various concepts that are used within the ELCC professional standards outside the country where the standards were conceived without due regard for contextualization. The study provides discussion on how the discourse of the ELCC standards shapes understandings and meanings of educational leadership and educational leaders.

A rational expectations model estimated for the UK is used to simulate macroeconomic policy under fixed and floating exchange rates. Under fixed rates inflation and interest rates are effectively set internationally; monetary policy only affects the reserves even in the short run and cyclical variations in fiscal policy are able to influence output in a fairly standard manner. Under floating rates, fiscal and monetary policy have rapid impacts on inflation and interest rates producing unfamiliar financial effects on expenditure which eliminate or reserve the conventional output multipliers. Stabilisation policy is still feasible but has to take account of these effects.
