Two-Dimensional Materials
Two-dimensional (2D) materials are defined as crystalline materials consisting of single- or few-layer atoms, in which the in-plane interatomic interactions are much stronger than those along the stacking direction. Since the success of monolayer graphene exfoliation, 2D materials have been extensively studied due to their unique structures and unprecedented properties. Among these fascinating studies, the most predominant focus has been on their atomic structures, defects, and mechanical behaviors and properties, which serve as the basis for the practical applications of 2D materials.

Corrective Rape
Corrective rape, also called curative or homophobic rape, is a hate crime in which one or more people are raped because of their perceived sexual orientation or gender identity. The common intended consequence of the rape, as seen by the perpetrator, is to turn the person heterosexual or to enforce conformity with gender stereotypes. The term corrective rape was coined in South Africa after well-known cases of corrective rapes of lesbian women such as Eudy Simelane (who was also murdered in the same attack) and Zoliswa Nkonyana became public. Popularisation of the term has raised awareness and encouraged LGBT+ people in countries across the world to come forward with their own stories of being raped as punishment for or in an attempt to change their sexual orientation or gender identity. Although some countries have laws protecting LGBT+ people, corrective rape is often overlooked.

Social Theory
Sciences and societies are increasing their demands of contributions from social theorists. International programs of research strengthen now the priorities of social impact and co-creation. Social impact means the presentation of evidence that scientific studies are contributing to social improvements, for instance, oriented to the UN Sustainable Development Goals; in order to develop and evaluate social impact, all sciences need the dialogue and collaboration of social theories. Co-creation means to create knowledge through dialogue between scientists and citizens, what also needs social theories. This demand is generating an increasing relevance of those social theories able to make these contributions, most of them, elaborated by networks and teams of different individuals from diverse disciplines. Traditional social theories created in the 19th and 20th centuries, mostly developed by individuals, provided important elements that are now included in the new theoretical process.

Palm Wine
The reference to palm wine as a drink with many functionalities has increased over the years. However, few empirical tests have been carried out on humans to substantiate the claims. This perspective looks at the biochemical and microbiological reports on palm wine to highlight the constituents that are associated with functional beverages. Based on the constituents of the drink, it may qualify as a multifunctional beverage because several investigators have demonstrated disease risk reduction, improved nutrition and health outcomes in many studies, albeit in rats rather than humans. The constituents found in functional beverages are present in the drink. However, when assessed under European Union regulations, fermented palm wine (from 3% alcohol) cannot be regarded as a functional beverage because beverages that contain over 1.2% alcohol cannot be approved for any claim on health or nutritional benefit. The fresh sap with much lower alcohol may be suitable after it is refined and subjected to scientific examination to determine quantities of the drink that can confer health benefits on humans.

Participative Decision Making (PDM)
Participative decision making (PDM) is the opportunity for an employee to provide input into the decision-making process related to work matters (i.e., work organization, task priority) or organizational issues, for example, when they have a say on promoting new strategy ideas. Elele and Fields state that PDM is a management initiative based on the ”theory Y”, which suggests that employees are interested in being committed and performing well if managers value their contributions in making decisions that affect the nature of work. The diverse opportunities to participate in the decision-making process can provide mutual benefits for employees and employers. Some writers have proposed that PDM enhances motivation, organizational commitment, and job satisfaction. The literature frames employee participation in different contexts, depending on the political, social, and legal environment of the countries.

Oceania
Oceania (UK: /ˌoʊsiˈɑːniə, ˌoʊʃi-, -ˈeɪn-/, US: /ˌoʊʃiˈæniə/ (listen), /-ˈɑːn-/) is a geographical region that includes Australasia, Melanesia, Micronesia, and Polynesia. Spanning the Eastern and Western hemispheres, Oceania is estimated to have a land area of 8,525,989 square kilometres (3,291,903 sq mi)[discuss] and a population of over 41 million. When compared with the other continents, the region of Oceania is the smallest in land area and the second smallest in population after Antarctica. Its six major population centres are Sydney, Melbourne, Brisbane, Perth, Auckland, and Adelaide. Oceania has a diverse mix of economies from the highly developed and globally competitive financial markets of Australia , French Polynesia, Hawaiʻi, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much less developed economies of Kiribati, Papua New Guinea, Tuvalu, Vanuatu, and Western New Guinea, while also including medium-sized economies of Pacific islands such as Fiji, Palau, and Tonga. The largest and most populous country in Oceania is Australia, and the largest city is Sydney. Puncak Jaya in Papua is the highest peak in Oceania at 4,884 m (16,024 ft). The first settlers of Australia, New Guinea, and the large islands just to the east arrived more than 60,000 years ago. Oceania was first explored by Europeans from the 16th century onward. Portuguese explorers, between 1512 and 1526, reached the Tanimbar Islands, some of the Caroline Islands and west Papua New Guinea. On his first voyage in the 18th century, James Cook, who later arrived at the highly developed Hawaiʻian Islands, went to Tahiti and followed the east coast of Australia for the first time. The arrival of European settlers in subsequent centuries resulted in a significant alteration in the social and political landscape of Oceania. The Pacific theatre saw major action during the Second World War, mainly between Allied powers the United States, Philippines (a US Commonwealth at the time) and Australia, and Axis power Japan. The rock art of Aboriginal Australians is the longest continuously practiced artistic tradition in the world. Most Oceanian countries are multi-party representative parliamentary democracies, with tourism being a large source of income for the Pacific Islands nations.

Shrimp Farming in the Philippines
Aquaculture serves the employment and food security needs of most Asian coastal countries, such as Bangladesh, China, India, Indonesia, the Philippines, Thailand, and Vietnam, which are all aquaculture-reliant countries with large aquaculture sectors. Aquaculture is a major driver of socioeconomic development in poor rural and coastal communities, particularly in Asia, and it relieves the pressure on, and helps to maintain the sustainability of, wild-caught species from rivers, lakes, and oceans, as it provides for the shortfalls of capture fisheries.  This industry has become a major source of food protein and it is predicted that it will support the seafood production as a sustainable alternative to wild-caught fish.

Historical Reliability of the Gospels
The historical reliability of the Gospels refers to the reliability and historic character of the four New Testament gospels as historical documents. Some believe that all four canonical gospels meet the five criteria for historical reliability; and others say that little in the gospels is considered to be historically reliable. Almost all scholars of antiquity agree that Jesus existed, but scholars differ on the historicity of specific episodes described in the Biblical accounts of Jesus, and the only two events subject to "almost universal assent" are that Jesus was baptized by John the Baptist and was crucified by the order of the Roman Prefect Pontius Pilate. Elements whose historical authenticity is disputed include the two accounts of the Nativity of Jesus, the miraculous events including the resurrection, and certain details about the crucifixion. According to the majority viewpoint the gospels of Matthew, Mark, and Luke, collectively referred to as the Synoptic Gospels, are the primary sources of historical information about Jesus and of the religious movement he founded. The fourth gospel, the Gospel of John, differs greatly from the first three gospels. Historians often study the historical reliability of the Acts of the Apostles when studying the reliability of the gospels, as Acts was seemingly written by the same author as the Gospel of Luke. Historians subject the gospels to critical analysis, attempting to differentiate, rather than authenticate, reliable information from possible inventions, exaggerations, and alterations. Since there are more than 15,000 New Testament manuscripts which present hundreds of thousands of textual variants, scholars use textual criticism to determine which gospel variants could theoretically be taken as 'original'. To answer this question, scholars have to ask who wrote the gospels, when they wrote them, what was their objective in writing them, what sources the authors used, how reliable these sources were, and how far removed in time the sources were from the stories they narrate, or if they were altered later. Scholars can also look into the internal evidence of the documents, to see if, for example, the document is misquoting texts from the Hebrew Tanakh, is making claims about geography that were incorrect, if the author appears to be hiding information, or if the author has made up a certain prophecy. Finally, scholars turn to external sources, including the testimony of early church leaders, writers outside the church (mainly Jewish and Greco-Roman historians) who would have been more likely to have criticized the early churches, and to archaeological evidence.
