In most sectors of the national economy, technical facilities are represented by unloading devices that extract bulk cargo from the freight rolling stock, store it for a certain time, and ship it to a similar or other type of transport. Objects intended for the implementation of the stages of loading, unloading, and various storage periods, including bulk cargos, are commonly referred to by the broad scientific community as transport and warehouse complexes (TWC). Most operations performed in the TWC are the movement of goods (internal movements, receiving or sending goods by various modes of transport. The authors clarified the concept of "transport and warehouse complex" - it is an element of the transport network of the region, providing communication of external transport systems of the regions and performing the functions of converting the cargo flow of the region into the cargo flow sent by the region. On the one hand, they perform functions of transshipment points in relation to deep (economic) warehouses, and on the other – the functions of storage facilities. Their primary purpose is determined and depends on a large number of factors, including: the size of the direct service area, the ratio of the design capacity of the warehouse to the volumes of deliveries and the use of bulk cargo, as well as the condition of roads in the serviced area, the uniformity of the receipt of bulk cargo and the availability of vehicles for their delivery to the consumer.

Racism in any society is fuelled by a number of factors, often acting independently of each other, or, at times, in concert with each other. On the one hand, anti-racism efforts rely on the alignment of four “system conditions” to stand a chance of successfully engaging and tackling racism. On the other hand, where these “system conditions” are not present, or where they are not in sync, this leads to “system failure”—a situation where racism is writ large in society and in the institutions therein, and where anti-racism efforts are severely hampered. Drawing on evidence from within the education sector and elsewhere in UK society, this paper examines how a lack of alignment between “system conditions” hampers antiracism efforts, and simultaneously reinforces racism in society and in institutions—leading to gridlock or “system failure” around anti-racism.

Scientific Imagination

Climatologists have recently introduced a distinction between projections as scenario-based model results on the one hand and predictions on the other hand. The interpretation and usage of both terms is, however, not univocal. It is stated that the ambiguities of the interpretations may cause problems in the communication of climate science within the scientific community and to the public realm. This paper suggests an account of scenarios as props in games of make-belive. With this account, we explain the difference between projections that should be make-believed and other model results that should be believed.

Despite the great interest that the scientific community has in quantum computing, the scarcity and high cost of resources prevent to advance in this field. Specifically, qubits are very expensive to build, causing the few available quantum computers are tremendously limited in their number of qubits and delaying their progress. This work presents new reversible circuits that optimize the necessary resources for the conversion of a sign binary number into two's complement of N digits. The benefits of our work are two: on the one hand, the proposed two's complement converters are fault tolerant circuits and also are more efficient in terms of resources (essentially, quantum cost, number of qubits, and T-count) than the described in the literature. On the other hand, valuable information about available converters and, what is more, quantum adders, is summarized in tables for interested researchers. The converters have been measured using robust metrics and have been compared with the state-of-the-art circuits. The code to build them in a real quantum computer is given.

The main objective of this chapter is to provide new insights into the economic and social value that financial literacy has for individuals and societies. Financial literacy has implications that are relevant both at a micro (especially for households) and macro-level (for the financial system and for the national economy as a whole). On the one hand, a lack of financial literacy put households a risk from making sub-optimal financial decisions and prevent them to maximize their wellbeing. On the other hand, financial literacy favors a better allocation of resources, reduces the risks associated with episodes of financial instability, and therefore, contributes to the increase of social welfare. The analysis and the empirical evidence showing the benefits (costs) of financial literacy (illiteracy) allows to conclude that policymakers have a key role to play implementing initiatives aiming to improve financial literacy of the population at all stages of life.

Integrate Data

Data warehouses (DWs) integrate data from different source systems in order to provide historical information that supports the decision-making process. The design of a DW is a complex and costly task since the inclusion of different data items in a DW depends on both users’ needs and data availability in source systems. Currently, there is still a lack of a methodological framework that guides developers through the different stages of the DW design process. On the one hand, there are several proposals that informally describe the phases used for developing DWs based on the authors’ experience in building such systems (Inmon, 2002; Kimball, Reeves, Ross, & Thornthwaite, 1998). On the other hand, the scientific community proposes a variety of approaches for developing DWs, discussed in the next section. Nevertheless, they either include features that are meant for the specific conceptual model used by the authors, or they are very complex. This situation has occurred since the need to build DW systems that fulfill user expectations was ahead of methodological and formal approaches for DW development, just like the one we had for operational databases.

The Relationship

The OECD defined corporate governance  as, enforce laws, rules and standards that define the relationship between company management on the one hand, shareholders, stakeholders or parties associated with the company on the other, and urge financial institutions to adopt those laws and standards in their systems to ensure universal classification, such laws and standards are called corporate governance. Some countries have adopted such standards, which are based on integrity and transparency, such as the Hashemite Kingdom of Jordan, but the apply these standards to protect the minority of shareholders in the joint stock companies are in conflict with certain legal provisions laid down by the Jordanian legislature in the companies Act. The Jordanian companies' law and some other financial laws have, of course, included a number of factors that encourage corporate governance, but on the other hand, we find texts that still impede the application of these standards and provide indicators that do not encourage the application of their standards and affect the rights of minority shareholders. The study will refer to the most important corporate governance criteria that balance the rights of the minority and majority shareholders with those that still need to be modified.

L’articolo delinea i momenti salienti nella storia della chirurgia, quali la scoperta dell’anestesia, dell’asepsi e antisepsi che ne hanno consentito l’ascesa dopo secoli di oscurità. Il desiderio di conoscenza appagato da tali scoperte si è spesso accompagnato a dilemmi etici da un lato e a resistenze ideologiche, da parte della comunità scientifica (spesso ostile alla genesi del nuovo nella medicina) dall’altro. È questo uno dei più forti ostacoli che i grandi del passato, coloro che hanno avuto il coraggio di andare controcorrente (rompendo i paradigmi esistenti), hanno dovuto superare. Questi uomini rappresentano uno stimolo per ricondurre il sapere scientifico ad un confronto attivo con l’etica al fine di sanare una dicotomia che ha radici antiche. L’antico, dunque, non è semplicemente passato ma rivive attraverso la narrazione storica di vite esemplari di medici. ---------- This article traces salient points in the history of surgery, such as the discovery of anesthesia, asepsis and antisepsis, which permitted surgery’s ascendancy after centuries of unimportance. Encouraged by such breakthroughs, the yearning to learn was often accompanied by ethical dilemmas on the one hand and on the other by ideological resistance on the part of the scientific community, which was often hostile to new medical findings. This was one of the greatest obstacles of the past for the distinguished individuals who had the courage to go against the tide, to break with existing paradigms, to overcome opposition to innovation. These men functioned as a stimulus to bring scientific knowledge head to head with ethics with the goal of healing ancient irreconcilable differences. The past is not simply the past; it lives on through the historical narrative of exemplary lives of certain physicians.

Proper Cooperation

Competitiveness and sustainability are inseparable concepts. Competitiveness cannot be interpreted in the short term, and thus it cannot exist without sustainability as well. At both the corporate and national economy level, only those who can maintain their outstanding performance, in the long run, are the winners in global competition. There are two roads to achieving these two goals simultaneously, and they can even be followed at the same time. On the one hand, moving away from quantitative factors towards quality, and on the other hand, looking for new resources and making old resources unlimited by using them in a sustainable, “green” manner. With the development of digitalisation, data is becoming a more important resource than ever before, while money and access to energy may become unlimited. No segment of the economy can ignore revolutionary changes, such as the green and digital transition, but proper cooperation between the state and the market is necessary to achieve and maintain competitiveness and sustainability.

Below is the Scientific Policy Presentation, a document created by Javier Marzal Felici, Professor of Audiovisual Communication at the Jaume I University of Castellón, and by Juan Antonio García Galindo, Professor of Journalism at the University of Málaga. It was commissioned by the Presidency and Governing Board of the Spanish Association of Communication Research (AE-IC) and written between July and October 2020. This report acts as a summary while making proposals; that is to say, it is “executive”. On the one hand, it gives an overview of the situation for research in the field of communication in Spain, gathering numerous reflections given by several dozens of researchers and members of AE-IC. On the other, the Scientific Policy Presentation proposes to stimulate or even “provoke” internal debate within the heart of AE-IC at a time when it is clearly perceived that the sphere of communication sciences has reached a notable level of maturity. Finally, those presenting it are attempting to gather the main concerns of a large part of the scientific community in the field of communication sciences in order to build future consensuses that are as broad as possible by presenting sixteen recommendations on scientific policy.

Wearable robotics is a field receiving increasing attention from the scientific community. It has great potential to improve rehabilitation process or increase the human capabilities but faces a number of challenges. On the one side, powerful actuation is required, leading to considerable system weight. On the other side, due to the close physical interaction with a human and taking into consideration safety requirements, the displacement of the actuators is crucial to the operational efficiency and functionality of exoskeleton devices. One possible solution for the design of an operational and efficient wearable device is to relocate its actuators out of joints and transmit the force by means of cable-based transmission systems. This paper presents an overview of various cable-based configurations correlated to conventional mechanical designs and their implementation in exoskeleton's structures and an overview of exoskeleton robots including comparison and trend analyses.
