The Wispy Terrain and Dione's Cryotectonic Features
The so-called Wispy Terrain, named after observing frequently appearing wispy streaks, markings, and lineaments in the images of the Voyager spacecraft, is one of the enigmatic features of the icy moon Dione (a satellite of Saturn). Its characteristics and formation have been the target of a long-lasting scientific debate and ongoing research, along with other cryotectonic features of the icy satellite.

The Development Process of DAUE
Driving analysis of urban expansion (DAUE) is usually implemented to identify the driving factors and their corresponding driving effects/mechanisms for the expansion processes of urban land, aiming to provide scientific guidance for urban planning and management. DAUE is defined to cover all related driving effect/relationship/mechanism research on urban expansion and includes the employed analysis methods within them, i.e., correlation analysis, regression analysis, causal analysis, and so on.

The Concept of Sustainability and the Sustainable Pillars
The concept of sustainability or sustainable development is based on the German word “Nachhaltigkeit”, which was defined in the book Sylvicultura Oeconomica, by von Carlowitz. Implementing sustainability can be traced back to the year 1713, when it was used in relation to the forest industry, along with an implemented discussion of whether a forest can recover from humans’ wood consumption.

The Bruun Rule
The Bruun Rule is a formula for estimating the magnitude of the retreat of the shoreline of a sandy shore in response to changes in sea level. Originally published in 1962 by Per Bruun, the Bruun Rule was the first to give a relationship between sea level rise and shoreline recession. The rule is a simple, two dimensional mass conversion, and remains in common use to estimate shoreline recession in response to sea level rise, despite criticism and modification, and the availability more complex alternate models.

Thai Highlands
The Thai highlands or Hills of northern Thailand is a mountainous natural region in the north of Thailand. Its mountain ranges are part of the system of hills extending through Laos, Burma, and China and linking to the Himalayas, of which they may be considered foothills. The highlands in the north of Thailand are characterized by a pattern of generally steep hill ranges, intermontane basins and alluvial gorges. Elevations are generally moderate, little above 2,000 metres (6,600 ft) for the highest summits. There is a wide range of elevations though, with floors ranging between 200 and 500 metres (660 and 1,640 ft) above sea level. Towards the Lao border, the divide to the Mekong basin becomes higher with peaks occasionally rising above 1,500 metres (4,900 ft) and streams flowing in narrow steep valleys. The climate is typical of tropical mountains with clearly delineated wet and dry seasons. Winter temperatures can be cool with frosts occurring most years at higher elevations, but no snow even on the highest peaks. The region of the Thai Highlands encompasses the nine administrative provinces of northern Thailand, based on the six-region system, as well as parts of Tak and Sukhothai Provinces. Some areas of the highlands are sparsely populated.

Terminology of the British Isles
The terminology of the British Isles refers to the various words and phrases that are used to describe the different (and sometimes overlapping) geographical and political areas of the islands of Great Britain, Ireland, and the smaller islands which surround them. The terminology is often a source of confusion, partly owing to the similarity between some of the actual words used, but also because they are often used loosely. In addition, many of the words carry both geographical and political connotations which are affected by the history of the islands. The purpose of this article is to explain the meanings of and relationships among the terms in use; however many of these classifications are contentious and are the subject of disagreement (See the British Isles naming dispute).

Teaching Sustainability in Planning and Design Education
Education for sustainable development (ESD) benefits school improvement and individual students, allowing them to ask critical questions about the status quo, clarify their values, and think systemically. In the fields of planning and design, including urban planning, regional planning, landscape architecture, and urban design, sustainability is vital to address the development dilemmas of environmental protection, urban development, economic activity, and social expectations. Design and planning decisions must consider a wide range of activities representing the goals of preservation, development, economic opportunities, social justice, and many others.

Taupo Volcano
Lake Taupo, in the centre of New Zealand’s North Island, is the caldera of a large rhyolitic supervolcano called the Taupo Volcano. This huge volcano has produced two of the world’s most violent eruptions in geologically recent times. The Taupo Volcano forms part of the Taupo Volcanic Zone, a region of volcanic activity that extends from Ruapehu in the South, through the Taupo and Rotorua districts, to White Island, in the Bay of Plenty region. Taupo began erupting about 300,000 years ago, but the main eruptions that still affect the surrounding landscape are the Oruanui eruption, about 26,500 years ago, which is responsible for the shape of the modern caldera, and the Hatepe eruption, dated 232 ± 5 CE. However, there have been many more eruptions, with major ones every thousand years or so (see timeline of last 10,000 years of eruptions). Considering recent history alone, the volcano has been inactive for an unusually long period of time, but considering its long-term activity, it was inactive for much longer between 8100 and 5100 BCE (3,000 year inactivity, compared to the current 1,800 years). Some volcanoes within the Taupo Volcanic Zone have erupted far more recently, however, notably a violent VEI-5 eruption of Mount Tarawera in 1886, and frequent activity of Whakaari/White Island, which erupted most recently in December 2019.

Taupo Volcanic Zone
The Taupō Volcanic Zone (TVZ) is a volcanic area in the North Island of New Zealand that has been active for the past two million years and is still highly active. Mount Ruapehu marks its south-western end and the zone runs north-eastward through the Taupo and Rotorua areas and offshore into the Bay of Plenty. It is part of the larger Central Volcanic Region that extends further westward through the western Bay of Plenty to the eastern side of the Coromandel Peninsula and has been active for four million years. The Taupo Volcanic Zone is widening east–west at the rate of about 8 mm per year. It is named after Lake Taupo, the flooded caldera of the largest volcano in the zone, the Taupo Volcano.

Sustainable Development in Higher Education
Higher education institutions (HEIs) are not insulated from the challenges facing the planet and have been tasked as key stakeholders in sustainable development (SD). Over the last five decades, there has been a shift toward the categories of SD work that necessitate a collaborative culture that is not traditionally inherent in HEIs. It is offered that when HEIs align their institutional capacities with worldwide efforts to achieve sustainable development goals (SDGs) by 2030 and foster an intentionally collaborative culture, they will become better equipped to face their own unique challenges: becoming “changemaker” universities; collaborating with each other in the knowledge economy; placing students at the center of the teaching and learning process; and fulfilling their “third mission” to partner with external stakeholders and society.
