The Byzantine rulers, considering themselves the legitimate continuation of the ancient Roman Empire, were known by the title of "Emperor."

The Byzantine rulers adopted the title of "Emperor" as they believed they were the rightful successors of the Roman Empire. The term "Byzantine Empire" itself is a modern designation, as the rulers and citizens of the time referred to their state as the Roman Empire.

Following the fall of the Western Roman Empire in 476 CE, the Eastern Roman Empire, with its capital in Constantinople (formerly Byzantium), emerged as a distinct political entity. The Byzantine emperors sought to maintain the traditions, culture, and institutions of the ancient Roman Empire, emphasizing their connection to the past.

They saw themselves as the heirs to the Roman legacy and viewed their rule as the continuation of the Roman imperial authority. Therefore, the title "Emperor" was used to assert their status and authority, signifying their claim as the legitimate successors of the ancient Roman Empire.

There was little immediate reaction to Cade's report that lithium helped alleviate the symptoms of manic patients because his findings contradicted the prevailing beliefs and understanding of mental illness at the time.

When Cade initially reported the beneficial effects of lithium in treating manic patients, the prevailing view of mental illness primarily focused on psychoanalytic theories and interventions. The concept of using medication to treat mental disorders was not widely accepted or recognized. Cade's findings challenged the existing paradigms and called for a shift in understanding mental illness as having biological components that could be addressed through pharmacological interventions.

The lack of immediate reaction to Cade's report can be attributed to the resistance and skepticism encountered when introducing novel ideas that challenge established beliefs. It often takes time for scientific discoveries and breakthroughs to gain acceptance and influence clinical practice. In the case of lithium's efficacy in treating manic patients, it required further research, replication of findings, and accumulating evidence before it became recognized as a standard treatment for bipolar disorder.

Cade's pioneering work played a significant role in changing the landscape of psychiatric treatment, leading to the incorporation of psychopharmacology as an essential component in managing mental illnesses.

Dieters often find it difficult to keep off the weight they have lost by dieting because of a few reasons.

Firstly, when people start dieting, they often restrict their calorie intake significantly. This causes their body to enter into a state of starvation, which slows down their metabolism. As a result, when they return to their normal eating habits, their body's metabolism is still slow, making it easier for them to gain weight.
Secondly, many diets are unsustainable in the long run. They often require dieters to cut out entire food groups or severely restrict their intake of certain foods. This can lead to feelings of deprivation, making it difficult for dieters to stick to the diet in the long run. Once they stop the diet, they often return to their old eating habits and gain back the weight they lost.
Thirdly, weight loss requires a lifestyle change, not just a temporary fix. Many dieters fail to make permanent changes to their diet and exercise habits, making it difficult for them to maintain their weight loss. It's important for dieters to adopt healthy habits that they can maintain in the long run to ensure their weight loss is sustainable.
Overall, dieters find it difficult to keep off weight they have lost by dieting because of factors such as a slow metabolism, unsustainable diets, and a lack of permanent lifestyle changes.

Psychologists have been debating the nature vs. nurture argument in a "either-or" approach, i.e., the provided statement is true, for a long time.

The relative significance of nature (genetics) versus nurture (environment) in influencing human behaviour and development has been the subject of a protracted dispute among psychologists for a lengthy amount of time.

However, this argument was not as simple as a "either-or" choice.

The nature versus nurture debate explored the extent to which genetic factors (nature) and environmental influences (nurture) shape individual characteristics, including personality traits, intelligence, and various behaviors.

Some claimed that genetics was the main factor, implying that our genetic make-up dictated our characteristics and behaviours. Others emphasised environmental elements, claiming that experiences, upbringing, and cultural influences had a greater impact.

The nature vs nurture argument has changed in recent years as academics have come to understand the intricate relationship between DNA and environment.It is now widely understood that both nature and nurture contribute to human development, and they are not mutually exclusive.

Genetic factors provide the groundwork, but how those genes are expressed and affected by the environment is vital in determining how people differ from one another.

In conclusion, the statement is true. For many years, psychologists debated the "either-or" nature vs. nurture issue, but modern understanding today recognises that both nature (genetics) and nurture (environment) play significant roles in human behaviour and development.
