Enhance Learning Experience with Mobile-Assisted Language Learning
With the growth of information and communication technology, technology-enhanced language learning has been increasingly regarded as a successful way to support learners with more interconnecting and collaborative language learning environments. Since smartphones have recently become an indispensable item in modern society, mobile-assisted language learning (m-learning) has been introduced to assist students’ language learning with the convenient features of digital devices and mobile technologies.

Christian State
A Christian state is a country that recognizes a form of Christianity as its official religion and often has a state church (also called an established church), which is a Christian denomination that supports the government and is supported by the government. Historically, the nations of Armenia, Aksum, Georgia, as well as the Roman Empire and Byzantine Empire declared themselves as Christian states. In the Middle Ages, the idea to establish a Pan-Christian state by uniting the countries within Christendom, became popular, along with the goal to recover territory in which Christianity historically flourished, such as the Middle East and North Africa. Today, several nations officially identify themselves as Christian states or have state churches, including Argentina , Costa Rica, Denmark (incl. Greenland), Dominican Republic, El Salvador, England , Faroe Islands, Georgia, Greece, Hungary, Iceland, Liechtenstein, Malta, Monaco, Norway , Samoa, Tonga, Tuvalu, Vatican City, and Zambia. A Christian state stands in contrast to a secular state, an atheist state, or another religious state, such as a Jewish state, or an Islamic state.

Apostles
In Christian theology and ecclesiology, apostles, particularly the Twelve Apostles (also known as the Twelve Disciples or simply the Twelve), were the primary disciples of Jesus according to the New Testament. In addition to Christian theology, Islamic theology also acknowledges the apostles in the Quran. During the life and ministry of Jesus in the 1st century AD, the apostles were his closest followers and became the primary teachers of the gospel message of Jesus. While Christian tradition often refers to the apostles as being twelve in number, different gospel writers give different names for the same individual, and apostles mentioned in one gospel are not mentioned in others. There is also an Eastern Christian tradition derived from the Gospel of Luke of there having been as many as 70 apostles during the time of Jesus' ministry. Paul is often referred to as an apostle, because he was directly taught and commissioned by a vision of Christ (Acts 9:4–9) during his journey to Damascus. The commissioning of the Twelve Apostles during the ministry of Jesus is recorded in the Synoptic Gospels. After his resurrection, Jesus sent eleven of them (minus Judas Iscariot, who by then had died) by the Great Commission to spread his teachings to all nations. This event has been called the Dispersion of the Apostles. In modern usage, missionaries under Pentecostal movements often refer to themselves as apostles, a practice which stems from the Latin equivalent of apostle, i.e. missio, the source of the English word missionary. For example, Saint Patrick (AD 373–463) was the "Apostle of Ireland", Saint Boniface (680–755) was the "Apostle to the Germans", Saint José de Anchieta (1534–1597) was the "Apostle of Brazil" and Saint Peter of Betancur (1626–1667) was the "Apostle of Guatemala". The period of early Christianity during the lifetimes of the apostles is called the Apostolic Age. During the 1st century AD, the apostles established churches throughout the territories of the Roman Empire and, according to tradition, through the Middle East, Africa, and India . Of the tombs of the apostles, all but two are claimed by premises of the Catholic Church, half of them located in the Diocese of Rome.

Duality (Mathematics)
In mathematics, a duality translates concepts, theorems or mathematical structures into other concepts, theorems or structures, in a one-to-one fashion, often (but not always) by means of an involution operation: if the dual of A is B, then the dual of B is A. Such involutions sometimes have fixed points, so that the dual of A is A itself. For example, Desargues' theorem is self-dual in this sense under the standard duality in projective geometry. In mathematical contexts, duality has numerous meanings. It has been described as "a very pervasive and important concept in (modern) mathematics" and "an important general theme that has manifestations in almost every area of mathematics". Many mathematical dualities between objects of two types correspond to pairings, bilinear functions from an object of one type and another object of the second type to some family of scalars. For instance, linear algebra duality corresponds in this way to bilinear maps from pairs of vector spaces to scalars, the duality between distributions and the associated test functions corresponds to the pairing in which one integrates a distribution against a test function, and Poincaré duality corresponds similarly to intersection number, viewed as a pairing between submanifolds of a given manifold. From a category theory viewpoint, duality can also be seen as a functor, at least in the realm of vector spaces. This functor assigns to each space its dual space, and the pullback construction assigns to each arrow f: V → W its dual f∗: W∗ → V∗.

Proto-Algonquian
Proto-Algonquian (commonly abbreviated PA) is the proto-language from which the various Algonquian languages are descended. It is generally estimated to have been spoken around 2,500 to 3,000 years ago, but on the question of where it was spoken, there is less agreement. The Algonquian family, which is a branch of the larger Algic language family, is usually divided into three subgroups: Eastern Algonquian, which is a genetic subgroup, and Central Algonquian and Plains Algonquian, both of which are areal groupings. In the historical linguistics of North America, Proto-Algonquian is one of the best studied, most thoroughly reconstructed proto-languages. It is descended from Proto-Algic.

Hamzanama
The Hamzanama (Persian/Urdu: حمزه نامه Hamzenâme, Epic of Hamza) or Dastan-e-Amir Hamza (Persian/Urdu: داستان امیر حمزه Dâstâne Amir Hamze, "Adventures of Amir Hamza") narrates the legendary exploits of Amir Hamza, or Hamza ibn Abdul-Muttalib, an uncle of Muhammad. Most of the stories are extremely fanciful, "a continuous series of romantic interludes, threatening events, narrow escapes, and violent acts". The Hamzanama chronicles the fantastic adventures of Hamza as he and his band of heroes fight against the enemies of Islam. The stories, from a long-established oral tradition, were written down in Persian, the language of the courts of Persianate societies, in multiple volumes presumably in the era of Mahmud of Ghazni. In the West, the work is best known for the enormous illustrated manuscript commissioned by the Mughal emperor Akbar about 1562. The text augmented the story, as traditionally told in dastan performances. The dastan (storytelling tradition) about Amir Hamza persists far and wide up to Bengal and Arakan, as the Mughal Empire controlled those territories. The longest version of the Hamzanama exists in Urdu and contains 46 volumes in approximately over 45,000 pages.

Excommunication of Catholic Politicians Who Support Abortion
Because the Catholic Church opposes abortion as a matter of doctrine, some Catholic bishops have refused or threatened to refuse communion, or threatened to declare excommunication upon Catholic politicians who support abortion. In some cases, officials have stated that ministers should refuse communion to such politicians per canon 915 of the 1983 Code of Canon Law; elsewhere, that the politicians should, on their own, refrain from receiving communion ad normam canon 916; and in other cases, excommunication has been suggested.

Reflective Façades
Reflection and transparency are two valuable properties associated with the use of glass as an architectural material. While proponents of modernism favored transparency over reflection, whether in its physical or conceptual implications, to justify the designs of façades of Modernist buildings and in architectural criticism, contemporary architects are revisiting the neglected trait of ‘reflection’.

Desert Island Discs
Desert Island Discs is a radio programme broadcast on BBC Radio 4. It was first broadcast on the BBC Forces Programme on 29 January 1942. Each week a guest, called a 'castaway' during the programme, is asked to choose eight recordings (usually, but not always, music), a book and a luxury item that they would take if they were to be cast away on a desert island, whilst discussing their lives and the reasons for their choices. It was devised and originally presented by Roy Plomley. Since 2006, the programme has been presented by Kirsty Young. More than 3,000 episodes have been recorded, with some guests having appeared more than once and some episodes featuring more than one guest. An example of a guest who falls into both categories is Bob Monkhouse, who appeared with his co-writer Denis Goodwin on 12 December 1955 and in his own right on 20 December 1998.
