1. Introduction

Specialization refers to the process of becoming an expert in a particular field, instead of focusing on a wide range of tasks. With advancements in science and technology, there has been a growing trend towards specialization in various areas, such as medicine, business, and education. This has also led to the development of specific advanced practice roles in different industries. Advanced practice is a term used to describe a level of practice, rather than a specific role. Such roles are ‘advanced’ as they require higher levels of decision-making and more autonomy. Advanced practice is not just limited to the medical profession. We can see this type of practice in social work, nursing, and other health and social care professions. In recent years, advanced practice roles have been developed in sectors such as paramedics and occupational therapists. The growth of advanced practice roles in the health sector reflects the demand for expert professionals who can support and complement medical services. This has been seen as a way to modernize healthcare systems and improve the efficiency and effectiveness of patient care. Advances in medicine and changes to the workings of the healthcare industry have allowed some medical professionals to move away from traditional, multidisciplinary roles and increase their level of specialization. One of the main reasons for this shift is the recognition that specialists who focus solely on one area are able to develop their expertise and provide a more efficient and high-quality service. As well as improved patient care, the adoption of advanced specialist practitioner roles has been identified as a method to ease demand on more traditional healthcare services. These have additional benefits for the wider healthcare system, including reduced waiting times and better integration between primary and secondary health services. Specialization in medicine is quite advanced. For example, in the field of surgery alone, we have specialists in orthopedic surgery, cosmetic surgery, cardiothoracic surgery, and neurosurgery. Various medical scientists have made significant contributions in highly specialized areas such as genetics, molecular biology, and the study of abnormal genes found in genetic disorders. This allows for further sub-specialization as well. The law is another area for great specialization. With the increasing globalization and commercialization of today’s world economies, it is inevitable that lawyers have been willing to specialize in a career in international business or trade law. In education, teachers have shown to become better skilled in their subject areas when they are given professional development in a particular area of the curriculum. Resistance to move away from old belief systems. The process of specialization requires individuals to give up the familiarity of general knowledge in a particular area in favor of seeking expertise in a smaller subfield. However, many may be afraid to give up that general knowledge around which their personal identity and professional work revolves. This is especially true when their employment requires versatility, such as a general practitioner in the medical field or a family attorney. Also, there is the understanding that the process of specialization comes with the appeal of prestige, recognition, and even financial incentives. However, it is difficult for individuals to avoid being influenced by these potential benefits and seek specialization even where it may not be necessary or productive.

1.1 Definition of Specialization

Specialization can be better understood by first defining what general practice is. General practice refers to a standard or routine practice and views things in a broad perspective. In medicine, for instance, general practitioners treat all acute and chronic illnesses, and provide preventive care and health education for all ages and both sexes. On the other hand, specialists focus on a specific disease and treatment, such as cardiologists who only treat heart-related illnesses, and provide a high level of patient care. Advanced practice nurses, as mentioned, are more specialized in a certain area. They should have the expertise in research and theory, and clinical and technical knowledge in their specialized area of practice such as psychiatric, adult health, oncology, pediatrics, or family health. Any nurses who want to gain specialization in a certain area need to acquire accredited post-basic programs for the specialty and pass the examination recognized by their respective professional groups. Such programs will train students to become specialists and to supervise nursing activities in both hospitals and the community and also to consult in their area of specialization. Ongoing clinical management by authority and continuous supervision to practice are required to ensure graduates’ safe practice. Specialized nurses are capable of performing many more complicated diagnostic and invasive procedures than a general nurse. For example, a nurse specialized in oncology – the study of cancer – can not only provide day-to-day care but also can perform a range of cancer treatments including chemotherapy. Advanced practice nurses can work as primary care providers and assist them in domestic health and health promotion, disease prevention, and management of chronic diseases. Focusing on the patient being “at the center of care” is the key to the success of nurses in advanced practice. By doing so, the patient can get the most personalized, comprehensive, and cost-effective care. By providing greater access to advanced practice nurses, a wealth of opportunity exists in contributing to patient-centered care in a range of professional specialties. The shift from physician-centered to patient-centered care also allows advanced practice nurses to practice a fuller scope of care and allows them to demonstrate “evidence-based practice” and “professional performance and quality” set by the respective accrediting body. With the concern about healthcare cost on the rise, the cost-effective nature of advanced practice nursing for specialized care is a genuine solution for sustainable quality healthcare provision. The emphasis and effect imparted by advanced practice nurses to the healthcare system would be enhanced further if the rest of the patient population could take advantage of having advanced practice nurses as primary care providers on a periodic basis. The impact of technology and globalization might have brought about the overall complexity of today’s healthcare environment, but this is allowing nurses to integrate different innovative discoveries in their specialized practices for the benefits of not only the patient but as well as the nurses themselves. However, it would be a greater transformation for nurses in advanced practice to take on and fully utilize the tremendous synergistic opportunities presented nowadays in healthcare transformation.

1.2 Importance of Advanced Practice

With the change in the healthcare system and progress in medical education, we have an opportunity now and the expectation of making greater improvements with further support for clinical educators’ specialty practice.

On July 23, 2015, the Secretary’s Advisory Committee on Training in Primary Care Medicine and Dentistry (ACTPCMD) approved a set of recommendations for increasing flexibility in faculty work effort at medical education programs, focused on building sustainable residency training “capacity in community-based ambulatory settings.” This is proposed “to improve access to comprehensive, coordinated, and longitudinal care for patients and communities,” per the ACTPCMD letter to the then Secretary of Health and Human Services.

The importance of clinical educators’ focus on specialty clinical practice has been recognized for the third educational objective – increased faculty flexibilities in work effort allocation. Such a general focus has been a common theme during the feedback from various national organizations over the past years as well. For example, in 2005, the Institute of Medicine identified the need for a “reproved focus on patients and their ability to access the healthcare system and its resources.” It was suggested in the report that medical education programs and teaching hospitals should adopt a more “candidate-centered approach that focuses on patients’ needs, expectations, and preferences” in order to advance the quality of medical education and patient care.The fourth important educational objective is to give clinical educators the time and resources necessary to become experts in their areas of specialization, often through advanced degrees in health-related fields. This would create an environment where all members of the healthcare team, including physicians, nurses, pharmacists, and other professionals, would benefit from more highly specialized clinical educators who would have the time and opportunity to provide even greater levels of clinical education. In turn, students and residents in these programs would be exposed to higher levels of expertise in a cycle of continuous improvement of clinical education and patient care.

1.3 Evolution of Specialization in Various Fields

The trend of advanced practice roles and specialization has already been shaped and implemented in many countries and across a variety of industries. It is clear that the support for new and ever-changing fields and specialties, with additional uptake in the near future, will provide these industries with the tools and knowledge they need to excel and to contribute to economical and social reform.

With the advance of technology and globalization, education has also witnessed the influence of specialization in various career options. Special education teachers may receive specific training in emotionally disturbed, developmentally delayed, or autistic students. In higher education, deans and academic administrators are primarily responsible for managing and leading the institution and they play a critical role in successfully advancing the organization. However, a dean will need to have an in-depth knowledge of a large range of subjects including course provisions, students affairs, faculties, and finance.

In the field of law, the American Bar Association recognizes not only specific legal specialties such as admiralty law and intellectual property law, but also non-legal careers such as education and business that law graduates may elect to pursue. The accreditation process for law schools and bar examinations are consistent with the adequate preparation requirement for profession expectations.

In engineering, the transition from a master builder model to multidisciplinary design teams has created new fields such as aerospace engineering, computer engineering, and biotechnology. Aerospace engineering focuses on the design, manufacture, and testing of aircraft and spacecraft, as well as satellites and missiles. Computer engineering emphasizes the development of computer hardware and software. Biotechnology is a broad field of biology and technology, encompassing biomedical research and innovative medical processes.

1. Introduction

The concept of family has always been one of the most important ideas in the human experience. Why? Because family has a significant and lasting impact on human life and well-being. It is one of, if not the most, influential variables that will shape a person’s development, and thus it becomes the most important factor that determines how a person will turn out. Family is the main catalyst for social, emotional and cognitive development. This is due both to the proximity of family relationships and the longevity, or stability, of these relationships. The fact that the impact of family on individual development is so strong raises the importance of defining family in terms of its makeup, function and how it contributes to the development of an individual. However, family today can be a confusing idea to pin down, to define in general, or even to see in a standard way. This is because family may be a relatively unexplored topic in a contemporary context, but it has long been a major social institution affecting our lives. More often than not, family is described as a social group made up of parents and their children, and this is what is covered by the definition provided in the Oxford English Dictionary. However, it is so easy to see many other results of human interactions with each other nature that all sway the definition a different way – in essence, it is society that defines what a family is. Even beyond our own experiences and opinions, there is opportunity to explore and make distinctions as to what is family in a global context including in comparison to family in other cultures. This broad concept of family according to Mendes, is categorized into a nuclear family and an extended family. The former consists of a married couple, and their own children as well, if there are any, met by occasional visits by close relatives, whereas the latter comprises three generations living in the same place and meet each other on a daily basis. This many possible variables now create division in how people define the family and thus, it might be a very general, outdated, or wrong kind of understanding to assume a terminological specificity. The purpose of this essay, therefore, is to explore and highlight the various underlying meanings of the much debated concept of family – providing a brief and broad explanation and evaluation of this complex topic that so many people and scholars have had so much to say about.

1.1. Definition of Family

Family is a fundamental social group in society and the child’s first introduction to the world. Not only is it the first and most natural society, but it is also the most significant cell of social life. Shepherding is another part of family because it is natural from the parent to our parents and then give the love to our child. However, this view highlights the positive power of family, but it can be argued that the positive and negative effects of family are not equal. Marriage is the foundation of family because the three of the children can be reduced the potential to have social problems, and the society can maintain stability as well. If marriage does not exist, the three may lead to the problem and it causes some changes in the structure of the society such as a descending trend on the birth rate, increasing the proportion of single parents, or decreasing the number of children per family. On the other hand, some people who are offered a different concept believe that individualism is more important for our life. The parents should give their children more freedom instead of waiting for the chance to give love. Most of the time, we are hearing the news of family abuse or the problem of family life. For example, the husband who is jobless might use alcoholism to release his tension and make him habitual of abusing, and the child who will have an insecure life. The recently available statistics about the number of women who die from the violence of family are increasing. The data, which has been taken from the police record, suggested that 62% of all violent arguments happen in the family. Every domestic argument will increase the potential for damage. It clearly shows that the problems of family affect the society in some ways. Every family is unique with different personalities, and they often refer to the conventional nuclear family. It consists of a married man and woman with a child or children. However, the important thing is that this traditional nuclear family enables the next generation to continue the tradition. Over time, different kinds of family forms have developed. It includes the extended family, such as the boy will live with his wife, his parents, and even his parents’ parents. The size of the family has reduced and fear of exposure of privacy. And there is a single-parent family, which consists of the parent and the child. It is because divorce has recently become the fashion in the modern world. Families are often the ones that are most subjected to the violence problem. The following paragraph will help us discuss the factors that lead to the problems of family.

1.2. Importance of Family

The phrase “Family is love” is a very good definition of what family is. Those words are from an enormous sensation that we experience when we bond with someone. We live with our parents and siblings from birth to death. If they smile, we smile. If they feel sad, we get sad. This is the magical touch of our parents and siblings. We want to see the next generation more productive and strong in physical and mental manners. If we develop a strong sense of commitment towards our responsibility, then it is 100% sure that we can easily transfer our problems to happiness. We learn from education how to become an energetic person in life, and there is a lot of education for children on how they are supposed to maintain their relationship with parents and other family members. When family is around us, it’s the happiest moment in our life because we are so close to people who love us and care for us. Our family encourages us to tackle and solve problems in life in the right way. When we see that our parents are always trying to bring happiness to us, then we feel relaxed and enjoy our life. When family provides good support, it can be easily seen how we relate to other things. For example, if we have a certain mindset and we know that our family is always on our side, then it is very easy to express our feelings. Our parents and family are a good way to learn about behavior because we do not spend most of our time with the most influential people in society. As far as health is concerned, we know very well that if our bond with family is strong, then in the case of illness, our family will provide maximum support. Our parents really play a very important role during our growing age, especially in our cognitive development through mutual conversation, playing, and reading. Family is important to every single human in the world. Every person needs someone in life whom they could trust and with whom they could share problems and express their feelings. The happiest moment in our life is when we give a smile to others, and it is so amazing when we see that the other person is smiling because of us. Family is love and a key to joy. Every individual is bonded with some family, and we learn about love, sacrifice, and helping others from our family. Whether it is our hobbies, work, sports, or games, we do them with more confident and satisfactory joy when done in isolation. When family provides support, it is a lot easier to chase our dreams because we know that our loved ones will never leave us alone in times of need.

1. Introduction

Nationalism is a political ideology that involves a strong identification of a group of individuals with a political entity defined in national terms, whether it is a nation that is recognized as a nation-state or a group that is recognized in international politics as having the right to self-determination. Self-determination is the idea that the community in which a people live has the right to self-government, the right to chart their own destiny. Nationalism is further oriented towards developing and maintaining a national identity based on shared characteristics such as culture, language, race, and political goals. A sense of national identity may be a by-product of the establishment of a national state, particularly in a ‘modernist’ theory where the search for freedom and a better way of life are primary motivating forces behind the desire for a nation to be recognized as a state. In historical terms, nationalism is often aligned with an anti-colonial movement. For example, the dissolution of the British Empire into separate nation-states revolves around the principle of nationalism, that most nations have the inalienable right to determine their own status and that no people should be forced to live in a colonial relationship. With regard to the rise of nationalism around the world, certain factors such as economic hardship and the erosion of national identities due to globalization have driven people to claim back their national identities, possibly through the use of populist nationalism. For instance, in Britain a sense of nationalism and a call for self-determination has led to Brexit, a movement which in essence wants to transfer the EU’s powers to the nation-state of the UK. Throughout history, the definition of nationalism and the nations that lay claim to national status have been ever-changing. The book then delves into the causes of rising nationalism, including economic, political, and cultural factors. These causes are often depicted as the roots of modern-day nationalist theory, and the authors explore the reasons why those that advocate for nationalism have been increasing in volume.

1.1 Definition of Nationalism

Nationalism is a complex term. The crucial aspect of nationalism is that the people who have a common sense of language, culture, and history want to live in their own country with a sovereign government. In fact, the nation is a basic unit of the international system and it is the way to realize the rationality, objectivity, and authenticity of people’s self-determination in the modern world. Nationalism not only facilitates the modernization of the whole country but also provides people a chance to integrate a group and achieve the target together. Modern nationalism often appears in nation-state politics. Hegemony is distinct from nationalism. Nations have a collective cluster of institutions, organizational symbols in national identities, national territory, and legal rights. The other terminology about nationalism is national concept. Nations are culturally diverse groups of people that form a natural entity that has the faculty of desire to develop the culture and preserve their identity. Nowadays, scholars agree that nationalism is an ambiguous phenomenon with many different possible manifestations. Virtually almost all of the critical discussion is focusing on modern nationalism. Because the modern nation-state is one unit from bottom to top and does not have the influence from the other unit. In the international arena, every state tries to maximize its own national interest, therefore, the majority of the world conflicts from the historical time until now are due to territorial disputes and nationalism.

1.2 Historical Background

Nationalism is a complex and evolving concept that has been difficult to define. For some scholars, nationalism is best understood as a political ideology that holds that a nation is the only legitimate basis for the state. For others, nationality is more than a political doctrine: it is a feeling of identity that is based on a shared sense of belonging and loyalty to a nation. A historical look into the development of nationalism and its impact on the global political landscape demonstrates that in the mid-19th century, as feelings of nationalism began to spread across Europe, they challenged dynastic and absolutist rulers in much of the world. As one after another large and multi-national empire collapsed, the result was the creation of many new and independent states; so today, the world map is still heavily influenced by the nationalist upsurges of the last two centuries. In fact, as late as the end of World War I in 1918, the world map was still dominated by large multi-national empires – the Austro-Hungarian, the Romanov in Russia, the Hohenzollern in Germany and the Ottoman Empire. However, the era of the empires had ended by 1945; dynastic and absolutist rulers trying to resist the forces of popular nationalism have long been relegated to the backwaters of history. In the modern era, scholars have been particularly interested in understanding how nationalism affects everyday politics and sociality in an increasingly interconnected world. Also, the devastating impact of World War II and the Holocaust forced scholars to pay attention to the powerful connections between nationalism and violence.

1. Introduction

The text is an essential read for anyone concerned about the environment. It explores the relationship between conservation biology and the health of our global ecosystems in such a comprehensive and engaging way. This is incredibly relevant in today’s world as we face increasing pressure to address issues like climate change on an international scale. The forward-thinking approach of the writers in assessing the future directions and potential of the science, even going as far as calling for a ‘unity of knowledge’ among research disciplines can give hope that one day humanity will begin to repair the damage we’ve inflicted on the natural world. It also provides an engaging and thought-provoking read on the enormous wealth of biodiversity present around the world today, outlined by the different chapters discussing the prevalence of ‘hotspots’ and the techniques involved in their conservation. This section will be of particular interest with the rise in big-data connected technologies that offer opportunities to enhance the informative power of our science yet is careful to distance itself from the mystifying tendencies of complex scientific theories. I believe that any student of environmental sciences would benefit from reading this text, but the way in which it is able to distill the key concepts and themes means that it will also be a fascinating read for those interested in general scientific developments. I believe that this text has the potential to become a set text for any undergraduate or introductory course in conservation biology. Indeed, the course that I myself lectured on was always searching for up to date and comprehensive material that could be easily accessible and easily understood. This text serves all of these requisites and removes the need to hand out and source dozens of academic papers that can be difficult to read for new students. I believe that, as one of the earliest comprehensive texts in the field, it will provide a strong grounding and context for new researchers as they explore the modern scientific literature and the rest of the course.

1.1 Importance of biodiversity preservation

The preservation of biodiversity is important for several reasons. First, biodiversity is an important part of the normal functioning of ecosystems. Every species plays a role in the ecosystem, and a loss of biodiversity could mean that the ecotoxicity of substances in the environment increases. In technical terms, an ecotoxic substance is something that hurts species within an ecosystem. Normally, the great number of species in an ecosystem means that all harmful substances in an ecosystem are decomposed and converted into less harmful substances. This decomposition takes place at many levels, but at the top are microorganisms which help to break down harmful substances. However, if a harmful substance were to be released into a biological system that was low in biodiversity, there is a higher chance that the substance would be much less decomposed and therefore its harmful effects would be much more likely to remain.

1.2 Threats to endangered species and ecosystems

The rate of extinction, according to the background information, has been rising dramatically since the 20th century due to human activity. Accelerated rates of habitat destruction, hunting, and introduction of alien species have increased the vulnerability of many populations and species, which ultimately endangers ecosystems. These activities are all driven due to a number of reasons like consumption by an ever increasing human population, growth in economic activity and technological advancement. The direct consequences of this is habitat loss, pollution, climate change, and over-exploitation of natural resources, which are the main driving forces of extinction. Hansen, a well respected environmental scientist who has published many works on conserving nature stated in their literature that “human exploitation of the environment led to 999 extinctions over the last four hundred years”. This rise in the rate of extinction is a significant concern as, unlike in previous centuries, the primary cause of extinction is due to activity of one species, humans. This is also stated in the Cambridge Encyclopedia of Extinction of the background information and is supported by the other literature. These different causes of population decline and the synergistic effects they can have on a species, are discussed as the current ‘Threats’ section of the chapter “Population Extinction”. Overall, the background information provides a good analysis into the human factors which effect the population of different species and refers to a variety of sources that have inspired the work of many modern scientists and ecologists, who work to prevent further extinctions. It also gives a basis to develop on a section discussing the ‘History of Extinction’ and the role key events, such as habitat destruction during the industrial revolution, has on the environment today.

1.3 Role of conservation biology in addressing these threats

Conservation biology is a science that provides the tools and knowledge to address the problems of small, declining populations. One way it does this is by increasing the effective population size of a species. The effective population size is a measure of a population’s genetic health. The concept of effective population size takes into account the fact that not all individuals in a population reproduce. It is always smaller than the total number of individuals in a population. However, a very small effective population size is dangerous for the long-term persistence of a population. This is because three important genetic processes work most effectively in large populations. First, large populations are better able to withstand the effects of harmful genes. Second, large populations are better able to adapt to changing environmental conditions through natural selection. Finally, large populations minimize the random changes in gene frequencies that occur in all populations. Such random changes, known as genetic drift, are most powerful in very small populations. By minimizing the random occurrence of harmful, neutral or beneficial genes, large populations increase the probability that a species will be able to produce enough healthy individuals to survive over time. In addition to increasing effective population sizes, conservation biologists strive to connect isolated populations in fragmented habitats. The migration of individuals between these populations, which can occur along corridors of suitable habitat types, assists in maintaining genetic diversity. For many species living in fragmented habitats, the land between habitat areas has been developed for human use. Reconnecting these areas to allow the movement of species, as well as promoting the maintenance of biodiversity hotspots, are areas in which conservation biologists can make a real and lasting impact. Programs that create such corridors are now increasingly recognized as essential tools in conservation biology. Consequently, key concepts that underlie the actions of conservation biologists include: minimizing the further destruction of natural habitats, protecting the genetic diversity of populations, and providing for the continued ability of populations to grow and interact with their environment, of which the maintenance of viable population sizes is a key.
