Parasitic Nutrition
Parasitic nutrition is a mode of heterotrophic nutrition where a parasitic organism lives on the body surface or inside the body of another type of organism (a host) and gets nutrition directly from the body of the host. Since these parasites derive nourishment from their host, this symbiotic interaction is often harmful to the host. Parasites depend on their host for survival, since the host provides nutrition and protection. As a result of this dependence, parasites have considerable modifications to optimise parasitic nutrition and therefore their survival. Parasites are divided into two groups: endoparasites and ectoparasites. Endoparasites are parasites that live inside the body of the host, whereas ectoparasites are parasites that live on the outer surface of the host and generally attach themselves during feeding. Due to the different strategies of endoparasites and ectoparasites, they require different adaptations to derive nutrients from their host. Parasites require nutrients to carry out essential functions including reproduction and growth. Essentially, the nutrients required from the host are carbohydrates, amino acids and lipids. Carbohydrates are utilised to generate energy, whilst amino acids and fatty acids are involved in the synthesis of macromolecules and the production of eggs. Most parasites are heterotrophs, so they therefore are unable to synthesise their own 'food' i.e. organic compounds and must acquire these from their host.

Corporate Social Responsibility in the Banking Sector
The concept of corporate social responsibility (CSR) extends the responsibility of companies beyond the interest of their owners to other stakeholder groups (including employees, customers, regulators, and community), highlighting the necessity to internalize the impact of business activities on the natural environment and the society. CSR is inevitably becoming an increasingly important part of almost every business. This is particularly true for the banking industry, which suffered substantial losses in reputation and public trust in the aftermath of the global financial crisis. Not surprisingly therefore, banks around the world have visibly intensified their CSR efforts.

Fatawa 'Alamgiri
Fatawa 'Alamgiri, also known as Al-Fatawa al-'Alamgiriyya (Arabic: الفتاوى العالمگيرية) or Al-Fatawa al-Hindiyya (Arabic: الفتاوى الهندية), is a 17th-century sharia based compilation on statecraft, general ethics, military strategy, economic policy, justice and punishment, that served as the law and principal regulating body of the Mughal Empire, during the reign of the Mughal emperor Muhammad Muhiuddin Aurangzeb Alamgir. It subsequently went on to become the reference legal text to enforce Sharia in colonial south Asia in the 18th century through early 20th century, and has been heralded as "the greatest digest of Muslim law made in India ".

TCP-based Congestion Control Algorithms
In today’s data networks, the main protocol used to ensure reliable communications is the transmission control protocol (TCP). The TCP performance is largely determined by the used congestion control (CC) algorithm, which main purpose is to avoid the congestion of the network that can be caused by a large burst of data traffic. TCP CC algorithms have evolved over the past three decades and a large number of CC algorithm variations have been developed to accommodate various communication network environments. Considering the importance of CC in communication networks, the fundamentals of the TCP as the main transport layer protocol and CC process have been explained in detail. Also, an encyclopedic overview of the most popular single-flow and multi-flow TCP CC algorithms with corresponding alternatives has been present. Future directions in the possible improvement of CC algorithms for implementation in complex heterogeneous networks composed of wired and wireless elements are lastly discussed in this encyclopedic work.

History of the Middle East
Home to the Cradle of Civilization, the Middle East (usually interchangeable with the Near East) has seen many of the world's oldest cultures and civilizations. This history started from the earliest human settlements, continuing through several major pre- and post-Islamic Empires through to the nation-states of the Middle East today. Template:Human history Egyptian civilization coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh. Mesopotamia was home to several powerful empires that came to rule almost the entire Middle East—particularly the Assyrian Empires of 1365–1076 BC and the Neo-Assyrian Empire of 911–609 BC. From the early 7th century BC and onwards, the Iranian Medes followed by Achaemenid Persia and other subsequent Iranian states empires dominated the region. In the 1st century BC, the expanding Roman Republic absorbed the whole Eastern Mediterranean, which included much of the Near East. The Eastern Roman Empire, today commonly known as the Byzantine Empire, ruling from the Balkans to the Euphrates, became increasingly defined by and dogmatic about Christianity, gradually creating religious rifts between the doctrines dictated by the establishment in Constantinople and believers in many parts of the Middle East. From the 3rd up to the course of the 7th century AD, the entire Middle East was dominated by the Byzantines and Sassanid Persia. From the 7th century, a new power was rising in the Middle East, that of Islam. The dominance of the Arabs came to a sudden end in the mid-11th century with the arrival of the Seljuq Turks. In the early 13th century, a new wave of invaders, the armies of the Mongol Empire, mainly Turkic, swept through the region. By the early 15th century, a new power had arisen in western Anatolia, the Ottoman emirs, linguistically Turkic and religiously Islamic, who in 1453 captured the Christian Byzantine capital of Constantinople and made themselves sultans. Large parts of the Middle East became a warground between the Ottomans and Iranian Safavids for centuries starting in the early 16th century. By 1700, the Ottomans had been driven out of Hungary and the balance of power along the frontier had shifted decisively in favor of the West. The British also established effective control of the Persian Gulf, and the French extended their influence into Lebanon and Syria. In 1912, the Italians seized Libya and the Dodecanese islands, just off the coast of the Ottoman heartland of Anatolia. In the late 19th and early 20th centuries, Middle Eastern rulers tried to modernize their states to compete more effectively with the European powers. A turning point in the history of the Middle East came when oil was discovered, first in Persia in 1908 and later in Saudi Arabia (in 1938) and the other Persian Gulf states, and also in Libya and Algeria. A Western dependence on Middle Eastern oil and the decline of British influence led to a growing American interest in the region. During the 1920s, 1930s, and 1940s, Syria and Egypt made moves towards independence. The British, the French, and the Soviets departed from many parts of the Middle East during and after World War II (1939–1945). The struggle between the Arabs and the Jews in Palestine culminated in the 1947 United Nations plan to partition Palestine. Later in the midst of Cold War tensions, the Arabic-speaking countries of Western Asia and Northern Africa saw the rise of pan-Arabism. The departure of the European powers from direct control of the region, the establishment of Israel, and the increasing importance of the oil industry, marked the creation of the modern Middle East. In most Middle Eastern countries, the growth of market economies was inhibited by political restrictions, corruption and cronyism, overspending on arms and prestige projects, and over-dependence on oil revenues. The wealthiest economies in the region per capita are the small oil-rich countries of Persian Gulf: Qatar, Kuwait, Bahrain, and the United Arab Emirates. A combination of factors—among them the 1967 Six-Day War, the 1970s energy crisis beginning with the 1973 OPEC oil embargo in response to U.S. support of Israel in the Yom Kippur War, the concurrent Saudi-led popularization of Salafism/Wahhabism, and the 1978-79 Iranian Revolution—promoted the increasing rise of Islamism and the ongoing Islamic revival (Tajdid). The Fall of the Soviet Union in 1991 brought a global security refocus from the Cold War to a War on Terror. Starting in the early 2010s, a revolutionary wave popularly known as the Arab Spring brought major protests, uprisings, and revolutions to several Middle Eastern and Maghreb countries. Clashes in western Iraq on 30 December 2013 were preliminary to the Sunni pan-Islamist ISIL uprising. The term Near East can be used interchangeably with Middle East, but in a different context, especially when discussing ancient times, it may have a limited meaning, namely the northern, historically Aramaic-speaking Semitic area and adjacent Anatolian territories, marked in the two maps below.

Online Shopping
Online shopping is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser. Consumers find a product of interest by visiting the website of the retailer directly or by searching among alternative vendors using a shopping search engine, which displays the same product's availability and pricing at different e-retailers. As of 2016, customers can shop online using a range of different computers and devices, including desktop computers, laptops, tablet computers and smartphones. An online shop evokes the physical analogy of buying products or services at a regular "bricks-and-mortar" retailer or shopping center; the process is called business-to-consumer (B2C) online shopping. When an online store is set up to enable businesses to buy from another businesses, the process is called business-to-business (B2B) online shopping. A typical online store enables the customer to browse the firm's range of products and services, view photos or images of the products, along with information about the product specifications, features and prices. Online stores typically enable shoppers to use "search" features to find specific models, brands or items. Online customers must have access to the Internet and a valid method of payment in order to complete a transaction, such as a credit card, an Interac-enabled debit card, or a service such as PayPal. For physical products (e.g., paperback books or clothes), the e-tailer ships the products to the customer; for digital products, such as digital audio files of songs or software, the e-tailer typically sends the file to the customer over the Internet. The largest of these online retailing corporations are Alibaba, Amazon.com, and eBay.

Internationalism (Politics)
Internationalism is a political principle that advocates greater political or economic cooperation among states and nations. It is associated with other political movements and ideologies, but can also reflect a doctrine, belief system, or movement in itself. Supporters of internationalism are known as internationalists and generally believe that humans should unite across national, political, cultural, racial, or class boundaries to advance their common interests, or that governments should cooperate because their mutual long-term interests are of greater importance than their short-term disputes. Internationalism has several interpretations and meanings, but is usually characterized by opposition to nationalism and isolationism; support for international institutions, such as the United Nations ; and a cosmopolitan outlook that promotes and respects other cultures and customs. The term is similar to, but distinct from, globalism and cosmopolitanism.

Digitalisation of organisations and COVID-19
The COVID-19 pandemic caused profound shifts in the functioning of organisations, with the increased mobilisation of the implementation of digitalisation processes in the activities of the members of these coordinated collective units. In this perspective, based on our academic experience and recent literature, this paper offers some dimensions that seem to us relevant to ponder with special urgency, and that will shape both organisations in the near future and an organisational culture that is, in many cases, renewed.
