Depersonalization
Depersonalization can consist of a detachment within the self, regarding one's mind or body, or being a detached observer of oneself. Subjects feel they have changed and that the world has become vague, dreamlike, less real, lacking in significance or being outside reality while looking in. Chronic depersonalization refers to depersonalization/derealization disorder, which is classified by the DSM-5 as a dissociative disorder, based on the findings that depersonalization and derealization are prevalent in other dissociative disorders including dissociative identity disorder. Though degrees of depersonalization and derealization can happen to anyone who is subject to temporary anxiety or stress, chronic depersonalization is more related to individuals who have experienced a severe trauma or prolonged stress/anxiety. Depersonalization-derealization is the single most important symptom in the spectrum of dissociative disorders, including dissociative identity disorder and "dissociative disorder not otherwise specified" (DD-NOS). It is also a prominent symptom in some other non-dissociative disorders, such as anxiety disorders, clinical depression, bipolar disorder, schizophrenia, schizoid personality disorder, hypothyroidism or endocrine disorders, schizotypal personality disorder, borderline personality disorder, obsessive–compulsive disorder, migraines, and sleep deprivation; it can also be a symptom of some types of neurological seizure. In social psychology, and in particular self-categorization theory, the term depersonalization has a different meaning and refers to "the stereotypical perception of the self as an example of some defining social category".

Depression-Risk Mental Pattern
Depression was reportedly one of the most common mental disorders among college students in China, with an incidence rate between 15% and 35%. Several explanations have been posited: undergraduates were confronted with numerous stressful life events inherent to adolescence and emerging adulthood, such as establishing their identity, emotional turmoil, achieving independence, entering unfamiliar environments, striving for academic performance, and selecting an occupation.

Depressive and Alcohol Use Disorders
Depressive disorders and alcohol use disorders are widespread among the general population and are significant public health and economic burdens. Alcohol use disorders often co-occur with other psychiatric conditions and this dual diagnosis is called comorbidity. Depressive disorders invariably contribute to the development and worsening of alcohol use disorders, and vice versa. The mechanisms underlying these disorders and their comorbidities remain unclear. Recently, interest in the lateral habenula, a small epithalamic brain structure, has increased because it becomes hyperactive in depression and alcohol use disorders, and can inhibit dopamine and serotonin neurons in the midbrain reward center, the hypofunction of which is believed to be a critical contributor to the etiology of depressive disorders and alcohol use disorders as well as their comorbidities. Additionally, calcium/calmodulin-dependent protein kinase II (CaMKII) in the lateral habenula has emerged as a critical player in the etiology of these comorbidities.

Derealization
Derealization is an alteration in the perception of the external world, causing sufferers to perceive it as unreal, distant, distorted or falsified. Other symptoms include feeling as if one's environment is lacking in spontaneity, emotional coloring, and depth. It is a dissociative symptom that may appear in moments of severe stress. Derealization is a subjective experience pertaining to a person's perception of the outside world, while depersonalization is a related symptom characterized by dissociation towards one's own body and mental processes. The two are commonly experienced in conjunction with one another, but are also known to occur independently. Chronic derealization is fairly rare, and may be caused by occipital–temporal dysfunction. Experiencing derealization for long periods of time or having recurring episodes can be indicative of many psychological disorders, and can cause significant distress among sufferers. However, temporary derealization symptoms are commonly experienced by the general population a few times throughout their lives, with a lifetime prevalence of up to 26-74% and a prevalence of 31–66% at the time of a traumatic event.

Descendants of the Bounty Mutineers
The descendants of the Bounty mutineers and their Tahitian consorts include the modern-day Pitcairn Islanders as well as a little less than half of the population of Norfolk Island. Their descendants also live in New Zealand, Australia, and the United States. Because of the scarcity of people on the island, many of the mutineers' children and grandchildren intermarried, with some marrying cousins and second cousins. Occasionally a new person would arrive on the island bringing with them a new surname (like the American Samuel Russell Warren, whose descendants still live on the island today).

Design Element Preferences in Public Facilities
As an important part of street-level urban design combined with infrastructure, public facilities have the potential to enhance the quality of efficient and modern services. At the same time, public facilities show the characteristic cultural landscape of the local area, and as markers of citizens’ impressions of the area, they need to be both recognizable and symbolic, so their design aesthetics cannot be ignored.

Design Thinking and Early School Dropout
Design Thinking (DT) is a design process originally used in the conception and validation of innovative and technologically efficient human-centered solutions for ill-formed problems. Being an iterative and collaborative process with a human point of view, DT allows adopters to improve several intrapersonal and interpersonal skills, like collaboration, creative thinking, leadership, presentation, project management, ethics, storytelling, negotiation, empathy, willingness to learn, etc. As such, DT has been adopted in several other areas and has also become highly relevant in educational contexts to develop the aforementioned skills in students. It has also been shown to contribute to minimizing the school dropout problem by keeping students motivated and integrated in the school context.

Designer Ecosystems for the Anthropocene
Accepting that nature and culture are intricately co-evolved has profound implications for the ethical, legal, philosophical and pragmatic dimensions of social and environmental policy. The way researchers think about nature affects how they understand and manage ecosystems. While the ideals of preserving wilderness and conserving ecosystems have motivated much conservation effort to date, achieving these ideals may not be feasible under Anthropocene conditions unless communities accept custodial responsibilities for landscapes and other species.

Designing Collaborative Energy Communities
Renewable energy has a crucial role in facing climate change. One promising strategy is the creation of energy communities that require active involvement from a bottom-up perspective. Their implementation is difficult, as they currently rely on local policies, community readiness, and technological availability.
