History of Autism Diagnosis and Treatment Research Paper

Introduction

Autism, a complex neurodevelopmental condition characterized by difficulties in social interaction, communication, and repetitive behavior patterns, has garnered increased attention over the years. It was first described by Leo Kanner in 1943, and later by Hans Asperger, which marked the beginning of formal recognition. Since then, the understanding of autism has evolved significantly, reflecting both scientific progress and changing societal attitudes.

Examining the history of autism diagnosis and treatment is of paramount importance for several reasons. Firstly, it provides valuable insights into the evolution of our understanding of this condition, shedding light on the changing diagnostic criteria and treatment modalities. Secondly, it allows us to appreciate the historical context, dispelling myths and misconceptions surrounding autism. Thirdly, studying the history of autism offers crucial lessons for shaping current and future approaches to diagnosis and intervention. By tracing the trajectory of autism through time, we gain a more comprehensive perspective on how society has addressed the needs of individuals on the autism spectrum.

The central research question of this paper is: How has the diagnosis and treatment of autism evolved over time, and what lessons can be gleaned from this historical journey? To answer this question, the paper seeks to achieve the following objectives: (1) Trace the historical development of autism diagnosis from early misconceptions to the current Autism Spectrum Disorder (ASD) criteria. (2) Investigate the historical approaches to treating individuals with autism, examining shifts in therapy paradigms. (3) Analyze the role of societal attitudes and stigmatization in shaping autism diagnosis and treatment. (4) Explore the global and cultural perspectives on autism, highlighting variations and challenges in different regions.

This research paper is structured into several sections to facilitate a comprehensive exploration of the history of autism diagnosis and treatment. After this introduction, the following sections will delve into the historical perspective on autism, the evolution of diagnostic criteria, early treatment approaches, shifting paradigms in diagnosis and treatment, contemporary approaches, societal attitudes and stigma, and global and cultural perspectives. The paper will conclude by summarizing key historical milestones, addressing current challenges, and considering future directions in the field of autism diagnosis and treatment.

Historical Perspective on Autism

The early descriptions of autism were often characterized by misconceptions and lack of clarity. In the early 20th century, children with autism were often misdiagnosed with conditions such as childhood schizophrenia or intellectual disability. Leo Kanner’s 1943 seminal paper, “Autistic Disturbances of Affective Contact,” played a pivotal role in rectifying these misconceptions. Kanner described a group of children with a distinct pattern of behavior characterized by social withdrawal and communication difficulties, leading to the formal recognition of autism as a unique condition.

One of the key milestones in the evolution of autism as a distinct condition was Hans Asperger’s work in the 1940s. Asperger’s research highlighted individuals who displayed similar characteristics to Kanner’s cases but exhibited milder symptoms, leading to the recognition of what would later be known as Asperger’s Syndrome. Additionally, the introduction of the term “infantile autism” by Kanner and the inclusion of autism in the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980 as “infantile autism, childhood onset type” marked significant steps in defining autism as a separate diagnostic category.

Several pioneers have made significant contributions to the field of autism research. Leo Kanner’s meticulous clinical descriptions were instrumental in identifying the core features of autism. Bernard Rimland, a psychologist and autism parent, founded the Autism Society of America and was influential in advocating for a more compassionate and supportive approach to autism. Ivar Lovaas, through his work on Applied Behavior Analysis (ABA), introduced effective behavioral interventions for individuals with autism. Additionally, Lorna Wing’s research on Asperger’s Syndrome and her advocacy for the broader autism spectrum concept have been highly influential. These pioneers, among others, have played essential roles in shaping our understanding of autism as a unique and diverse spectrum of conditions.

The Evolution of Diagnostic Criteria

The emergence of formal diagnostic criteria for autism can be traced back to Leo Kanner’s groundbreaking work in 1943. Kanner’s detailed descriptions of a group of children with “autistic disturbances of affective contact” laid the foundation for identifying a distinct condition. These early criteria included a focus on social withdrawal, communication deficits, and repetitive behaviors. Subsequently, Hans Asperger’s work, particularly his recognition of milder cases, contributed to the expansion of diagnostic criteria, acknowledging the broader spectrum of autism. The concept of early diagnosis became more prominent in the late 20th century, emphasizing the importance of identifying autism in early childhood.

Over the decades, significant developments in the diagnostic process have occurred. In the 1970s and 1980s, the introduction of standardized assessment tools, such as the Childhood Autism Rating Scale (CARS) and the Autism Diagnostic Interview (ADI), aimed to provide more structured and objective methods for diagnosing autism. The development of the Autism Diagnostic Observation Schedule (ADOS) in the 1990s added further precision to diagnostic evaluations. These instruments facilitated a more systematic approach to diagnosing autism, promoting consistency in the assessment process. Additionally, the integration of neuroimaging and genetic testing in recent years has enhanced our understanding of the underlying biological markers associated with autism.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) has played a central role in shaping the diagnostic criteria for autism. The DSM-III, published in 1980, introduced the term “infantile autism, childhood onset type” as a distinct diagnostic category, marking a significant milestone in the recognition of autism. Subsequent revisions of the DSM refined the criteria further. The publication of the DSM-5 in 2013 brought about a significant change, replacing the term “autistic disorder” with “Autism Spectrum Disorder (ASD),” reflecting the broader conceptualization of autism. The DSM-5 criteria emphasize the importance of assessing the severity of symptoms and incorporate the previously separate diagnoses of Asperger’s Syndrome and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) into the ASD diagnosis. This evolution in the DSM criteria reflects ongoing efforts to capture the heterogeneity and complexity of the autism spectrum.

These developments in diagnostic criteria have improved the accuracy and consistency of autism diagnoses, enabling early identification and intervention, and contributing to a better understanding of the condition.

Early Treatment Approaches

The early history of autism treatment is marked by a range of approaches that were rooted in misconceptions and a limited understanding of the condition. Historically, the management of autistic individuals often involved institutionalization, segregation, and treatments that were based on misguided beliefs. These approaches were shaped by societal attitudes and a lack of awareness about autism.

In the early 20th century, autism was often misunderstood, and individuals with the condition were frequently misdiagnosed with conditions like schizophrenia or intellectual disability. As a result, many children with autism were placed in psychiatric hospitals or institutions. The prevailing belief was that institutionalization was the most appropriate response to what were perceived as challenging or abnormal behaviors.

One notable historical institution is the Vienna Institute for the Feeble-Minded, where psychoanalyst Wilhelm Reich, a student of Sigmund Freud, conducted experiments in the 1920s and 1930s. Reich believed that autism was the result of repressed emotions in mothers, particularly mothers of autistic children. His controversial therapy involved trying to help mothers release these repressed emotions, with the belief that it would cure their children. This approach, though well-intentioned, had no scientific basis and is now regarded as both ineffective and ethically problematic.

Psychoanalysis and behaviorism were two dominant psychological paradigms in the early-to-mid 20th century, and both had an impact on early treatments for autism.

Psychoanalysis, championed by figures like Sigmund Freud and Bruno Bettelheim, suggested that autism was a result of emotional and psychological factors, particularly problematic parenting. Bettelheim, in particular, promoted the “refrigerator mother” theory, arguing that cold, unemotional mothers caused autism in their children. This harmful and unfounded theory further stigmatized families and had a detrimental impact on how autism was perceived and treated.

Behaviorism, on the other hand, was popularized by B.F. Skinner and had a more significant influence on early interventions. Behaviorist approaches focused on modifying behavior through conditioning and reinforcement. Applied Behavior Analysis (ABA), a behaviorist approach, was developed as a treatment for autism in the 1960s and became one of the earliest structured interventions. ABA emphasizes breaking down complex behaviors into smaller components and using reinforcement to encourage desired behaviors.

The historical methods and theories surrounding autism treatment raise ethical and moral concerns. The institutionalization of individuals with autism and the use of unproven treatments had profound ethical implications. Many of these early practices resulted in the isolation and mistreatment of autistic individuals, and their well-being and individual rights were often disregarded.

The “refrigerator mother” theory promoted by psychoanalysts like Bettelheim not only caused undue blame and guilt in parents but also delayed the development of more effective, evidence-based interventions. The ethical issue here lies in the stigmatization and emotional distress inflicted on parents, as well as the negative impact on the autistic individuals themselves.

Behaviorist approaches, particularly ABA, have faced ethical scrutiny, especially when applied without consideration for an individual’s autonomy and consent. Critics argue that ABA’s focus on compliance and normalization can suppress the expression of autistic traits and may be distressing for some individuals. Ethical debates revolve around issues of consent, individuality, and the balance between intervention and acceptance.

In conclusion, the historical management of autism was characterized by a lack of understanding, misguided theories, and treatments that often had detrimental consequences. The impact of psychoanalysis, particularly the “refrigerator mother” theory, and the behaviorist approaches, such as ABA, underscore the ethical complexities in the history of autism treatment. These early approaches served as a backdrop for the development of more evidence-based and ethical interventions, emphasizing the importance of learning from the past to improve the quality of life for individuals with autism.

Shifting Paradigms in Autism Diagnosis and Treatment

The Influence of Leo Kanner’s and Hans Asperger’s Work

Leo Kanner and Hans Asperger, in their groundbreaking research, played a significant role in shaping the understanding and treatment of autism. Their work not only led to the recognition of autism as a distinct condition but also influenced subsequent diagnostic and therapeutic paradigms.

Kanner’s work, particularly his 1943 paper “Autistic Disturbances of Affective Contact,” provided the first comprehensive clinical description of autism. He highlighted a group of children with a unique pattern of behaviors, including social withdrawal, communication difficulties, and repetitive behaviors. This foundational work established autism as a separate and identifiable condition, setting the stage for further research and clinical practice.

Hans Asperger’s work, conducted independently in Austria, introduced the concept of a broader autism spectrum. He recognized individuals with milder symptoms who exhibited social and communication difficulties but often had unique talents and capabilities. Asperger’s distinction between “autistic psychopathy” and “autistic intelligence” contributed to the understanding of the heterogeneity within the autism spectrum. His work later led to the recognition of Asperger’s Syndrome as a subtype of autism.

The influence of Kanner and Asperger’s work extended to diagnostic criteria. Their insights into the core features of autism provided a foundation for early diagnostic guidelines. However, it was not until the publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980 that autism was formally recognized as a distinct diagnostic category. This change was a crucial step in establishing standardized diagnostic criteria, setting the stage for more accurate and consistent identification of autism.

The Rise of Early Intervention Programs

The recognition of autism as a distinct condition and the desire for better outcomes for affected individuals led to the development of early intervention programs. Early intervention is based on the premise that providing targeted support and therapies during a child’s formative years can have a significant impact on their long-term development and functioning.

One of the pioneering early intervention programs was the Early Start Denver Model (ESDM). Developed in the 1980s and refined over subsequent years, the ESDM is an evidence-based, comprehensive early intervention approach for children with autism. It combines developmental and behavioral principles and has been shown to improve social, cognitive, and communication skills in young children with autism.

The concept of early intervention was further reinforced by research demonstrating the brain’s neuroplasticity and the potential for neural development in response to intervention during early childhood. This understanding highlighted the importance of identifying autism and implementing interventions as early as possible.

Early intervention programs typically employ a multidisciplinary approach, involving speech and language therapists, occupational therapists, behavioral therapists, and educators. They often focus on improving social communication, language development, and adaptive skills. The effectiveness of these programs has led to a shift in autism diagnosis and treatment, emphasizing the value of early identification and intervention to maximize an individual’s potential.

The Deinstitutionalization Movement and Its Effect on Treatment

The deinstitutionalization movement, which gained momentum in the mid-20th century, had a profound effect on the treatment of individuals with autism. This movement sought to transition individuals with developmental disabilities, including autism, from large, segregated institutions into community-based settings.

In the past, many individuals with autism were confined to large, overcrowded institutions with limited access to education, therapy, and individualized care. These institutions often lacked the necessary resources and expertise to support the diverse needs of autistic individuals. Deinstitutionalization aimed to rectify these shortcomings by moving towards a more community-based and inclusive approach to care.

As part of the deinstitutionalization movement, the focus shifted from isolating autistic individuals to integrating them into mainstream society. This shift had a profound impact on the treatment of autism by emphasizing community inclusion, access to education, and individualized support services. It led to the development of community-based services, educational opportunities, and residential programs designed to enhance the quality of life for individuals with autism.

The deinstitutionalization movement also underscored the importance of human rights and the autonomy of individuals with autism. It addressed the ethical concerns surrounding institutionalization and the need for a more compassionate and individualized approach to treatment.

In summary, the influence of Kanner and Asperger’s work, the rise of early intervention programs, and the deinstitutionalization movement have collectively contributed to significant shifts in autism diagnosis and treatment. These developments have emphasized the importance of early identification, targeted interventions, and a more inclusive and person-centered approach to supporting individuals with autism.

Contemporary Approaches to Autism Diagnosis and Treatment

The Role of the Autism Spectrum Disorder (ASD)

Diagnosis The diagnosis of Autism Spectrum Disorder (ASD) has become a central component of contemporary approaches to autism. The term “spectrum” reflects the recognition that autism encompasses a wide range of abilities, challenges, and characteristics. The introduction of ASD as a diagnostic category in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013 marked a significant evolution in the understanding of autism.

The ASD diagnosis is based on a comprehensive evaluation that includes an assessment of social communication, restricted and repetitive behaviors, and the level of functional impairment. This diagnostic framework acknowledges the heterogeneity within the autism spectrum and recognizes the need for individualized support and intervention. It also emphasizes the importance of assessing the severity of symptoms, ranging from mild to severe, to better tailor treatment plans.

The ASD diagnosis plays a critical role in accessing services and support. Individuals diagnosed with ASD may be eligible for various interventions and therapies, including early intervention, educational services, and specialized medical care. Moreover, the diagnosis informs research, advocacy, and the allocation of resources to address the diverse needs of individuals on the autism spectrum.

Evidence-Based Interventions and Therapies

Contemporary approaches to autism treatment emphasize evidence-based interventions and therapies. The importance of evidence-based practices is rooted in the need to provide effective, scientifically validated treatments that address the core challenges faced by individuals with autism.

One of the most widely recognized evidence-based interventions for autism is Applied Behavior Analysis (ABA). ABA is a behaviorist approach that utilizes systematic analysis of behavior to understand and modify responses to the environment. It has demonstrated efficacy in improving a range of skills, from communication and social interaction to reducing challenging behaviors.

Speech and language therapy is another evidence-based intervention, focusing on improving communication skills and language development. Occupational therapy helps individuals with sensory and motor challenges develop independence in daily living skills, while physical therapy addresses motor difficulties.

Social skills training programs are designed to enhance the ability of individuals with autism to engage in social interactions and develop meaningful relationships. Cognitive-behavioral therapy (CBT) has also been adapted for individuals with autism to address emotional regulation and anxiety.

Contemporary evidence-based interventions often take a multidisciplinary approach, combining multiple therapies and interventions tailored to the specific needs of the individual. Early intervention remains a cornerstone of contemporary treatment, as research consistently shows that starting interventions in early childhood can lead to better outcomes.

Behavioral, Educational, and Medical Interventions

Contemporary approaches to autism treatment encompass a wide range of behavioral, educational, and medical interventions. These interventions are tailored to the individual’s needs and can be delivered in a variety of settings, including home, school, and clinical environments.

Behavioral interventions, such as ABA, focus on modifying behaviors and teaching new skills through structured, goal-oriented techniques. Positive behavior support (PBS) is another behavioral approach that emphasizes identifying and reinforcing positive behaviors while minimizing challenging ones.

Educational interventions aim to provide individuals with autism the tools and strategies they need to thrive in school settings. These may include individualized education programs (IEPs) or other specialized educational plans. Inclusion programs, which integrate autistic students into mainstream classrooms with appropriate support, are becoming more common.

Medical interventions are often used in conjunction with behavioral and educational approaches. Medications may be prescribed to address specific challenges associated with autism, such as anxiety, hyperactivity, or sensory sensitivities. However, medication should be carefully considered and monitored, with potential benefits weighed against possible side effects.

Challenges and Controversies in Contemporary Diagnosis and Treatment

Contemporary approaches to autism diagnosis and treatment are not without challenges and controversies. Some of the notable issues include:

1. Overdiagnosis and Misdiagnosis: The expanded recognition of the autism spectrum has raised concerns about overdiagnosis and misdiagnosis. Some individuals may receive an autism diagnosis when they do not truly meet the criteria, while others may go undiagnosed due to variations in presentation.
2. Disparities in Access to Services: Disparities in access to diagnosis and treatment services persist. Factors such as socioeconomic status, race, and geographic location can affect an individual’s access to quality care and support.
3. Controversies Surrounding ABA: Although ABA is considered one of the most effective evidence-based interventions, it has faced criticism from some advocacy groups and self-advocates who argue that it can be overly controlling and compliance-oriented. Ethical concerns surrounding ABA, particularly when implemented without individual consent, have also been raised.
4. Balancing Individuality and Intervention: The tension between embracing neurodiversity and providing intervention remains a complex issue. The neurodiversity movement advocates for the acceptance of autistic individuals as they are, while some therapies aim to modify behaviors and characteristics to align with societal norms.
5. Lack of Standardization: The wide range of available interventions and services often lack standardization, making it challenging for families and professionals to navigate the diverse options and choose what is most appropriate for a particular individual.

In conclusion, contemporary approaches to autism diagnosis and treatment reflect a more nuanced understanding of autism as a spectrum, emphasizing individualized, evidence-based, and multidisciplinary care. However, challenges and controversies persist, underscoring the importance of ongoing research and dialogue to ensure the best possible outcomes for individuals on the autism spectrum.

Societal Attitudes and Stigma

The Impact of Societal Attitudes on the Diagnosis and Treatment of Autism

Societal attitudes have played a crucial role in shaping the diagnosis and treatment of autism. Historically, misconceptions and negative stereotypes have influenced the perception of individuals with autism, impacting their access to proper diagnosis and appropriate interventions.

1. Misconceptions and Stigmatization: Societal attitudes towards autism have often been marked by misunderstanding and stigma. Early misconceptions, such as the “refrigerator mother” theory, placed blame on parents and perpetuated negative stereotypes about the cause of autism. Such misconceptions hindered early diagnosis and appropriate treatment, as they discouraged parents from seeking help and reinforced feelings of shame.
2. Barriers to Diagnosis: Societal attitudes have also posed barriers to the diagnosis of autism. Negative stereotypes can lead to reluctance on the part of healthcare providers and educators to identify and diagnose autism, further delaying interventions and support. Stereotypes about autism being a “hopeless” condition have perpetuated low expectations and limited access to educational opportunities for autistic individuals.
3. Stigmatization of Sensory Differences: Sensory sensitivities are common in autism, but societal attitudes often lack understanding and empathy for these differences. Loud noises, bright lights, and other sensory triggers can lead to social exclusion, misunderstandings, and discrimination, further affecting the well-being of autistic individuals.

Advocacy and Awareness Movements

The impact of societal attitudes on autism diagnosis and treatment has spurred advocacy and awareness movements, which have significantly influenced the way autism is perceived and supported.

1. Parent and Self-Advocacy: Parents of autistic children and autistic self-advocates have played a vital role in changing societal attitudes. Organizations such as the Autism Society of America, the Autistic Self Advocacy Network (ASAN), and Autism Speaks have advocated for increased awareness, acceptance, and support. These advocacy groups have pushed for policies, services, and research that prioritize the well-being and rights of autistic individuals.
2. Neurodiversity Movement: The neurodiversity movement has gained momentum in recent years, challenging the medical model of autism and promoting the idea that neurodiversity, like biodiversity, is a natural and valuable part of human diversity. This movement advocates for the acceptance of autistic individuals as they are, rather than trying to “cure” or change them. It emphasizes the importance of accommodating and valuing neurodiverse perspectives.
3. Increased Awareness Campaigns: Public awareness campaigns, such as Autism Awareness Month, have raised visibility and understanding of autism. These efforts have sought to counteract stereotypes, foster empathy, and encourage inclusion. The “Light It Up Blue” campaign by Autism Speaks and the “Red Instead” campaign initiated by the neurodiversity movement are examples of campaigns with differing approaches to autism awareness.

The Role of Media and Pop Culture in Shaping Perceptions

Media and pop culture play a significant role in shaping societal attitudes towards autism. Representations of autism in television, film, literature, and news media have the power to influence public perception and understanding of the condition.

1. Positive and Accurate Representations: Media can provide positive and accurate portrayals of autism, which can contribute to increased awareness and understanding. TV shows like “The Good Doctor” and “Atypical” have featured autistic characters and highlighted their unique strengths and challenges. These representations help humanize autism and create empathy among viewers.
2. Stereotypes and Misconceptions: On the flip side, media can perpetuate stereotypes and misconceptions about autism. Sensationalist news stories or portrayals of individuals with autism as either “geniuses” or “burdens” can reinforce misunderstandings and stigma.
3. Autistic Creators and Voices: The involvement of autistic creators and voices in media and entertainment has been instrumental in providing authentic and diverse perspectives on autism. Authors, filmmakers, and artists who are on the spectrum themselves bring valuable insights and authenticity to their work, challenging conventional narratives.

In conclusion, societal attitudes and stigma have historically shaped the diagnosis and treatment of autism, often hindering access to appropriate support and interventions. However, advocacy and awareness movements, as well as evolving media representations, have contributed to changing perceptions of autism and promoting greater acceptance and understanding. Continuing efforts to challenge stereotypes, foster empathy, and advocate for the rights of autistic individuals are essential in shaping a more inclusive and equitable future for those on the autism spectrum.

Cultural and Global Perspectives

Autism Diagnosis and Treatment in Different Cultures

Autism diagnosis and treatment vary significantly across cultures due to cultural norms, beliefs, and healthcare systems. Understanding these differences is essential to ensure that autism interventions are culturally sensitive and effective.

1. Cultural Variation in Diagnosis: Cultural perspectives on autism influence the way it is diagnosed. Some cultures may have unique beliefs about child development, leading to delays or misdiagnoses. In some Asian cultures, for example, there may be a preference for considering certain behaviors as part of a child’s temperament rather than signs of autism. As a result, autism may be underdiagnosed or diagnosed at a later age in some cultural contexts.
2. Cultural Variations in Treatment Approaches: Cultural factors influence the choice of treatment and interventions. In some cultures, traditional or alternative therapies may be preferred over evidence-based practices. Family and community support systems also differ, impacting the availability and accessibility of interventions.
3. Linguistic and Communication Challenges: Language and communication barriers can complicate autism diagnosis and treatment, especially in multicultural societies. Autistic individuals from diverse linguistic backgrounds may require specialized assessment and intervention strategies.
4. Cultural Stigma and Discrimination: Stigmatization and discrimination against individuals with autism can be more pronounced in certain cultural contexts. This can affect access to healthcare, educational opportunities, and social inclusion. Addressing cultural stigma is crucial for providing equitable support.

Global Initiatives and Challenges in Addressing Autism

Autism is a global issue, and efforts to address it must consider the diversity of challenges and opportunities that different regions face.

1. Lack of Resources and Awareness: Many countries, especially low-income and middle-income nations, face challenges related to limited resources for autism diagnosis and treatment. Access to trained professionals, diagnostic tools, and evidence-based interventions can be severely restricted.
2. Global Initiatives: International organizations, such as the World Health Organization (WHO), and local autism advocacy groups have initiated efforts to address the challenges associated with autism worldwide. The WHO’s Mental Health Gap Action Programme (mhGAP) includes autism as part of its focus, aiming to improve access to care in low-resource settings.
3. Cultural Competence and Adaptation: Culturally competent interventions are essential for addressing autism on a global scale. Efforts to adapt evidence-based practices to cultural contexts are crucial to ensure interventions are effective and accepted.
4. Knowledge Exchange and Collaboration: International collaboration and knowledge sharing among researchers, practitioners, and advocacy groups are essential for advancing the understanding of autism and its treatment. Collaborative efforts can facilitate the development of culturally relevant interventions and improve global awareness.
5. Human Rights and Inclusion: Advocacy for the rights and inclusion of autistic individuals is a global concern. Organizations like the United Nations have emphasized the importance of recognizing the human rights of individuals with disabilities, including those with autism, and promoting inclusive policies and practices.

In summary, cultural and global perspectives on autism diagnosis and treatment reveal significant variations in approaches, challenges, and opportunities. Cultural factors influence the recognition and understanding of autism, as well as the choice of interventions. Global efforts, including international initiatives and collaborations, are essential to address the diverse needs of individuals with autism worldwide, improve access to appropriate care, and promote acceptance and inclusion on a global scale.
