Types of diffusion
Contagious expansion diffusion involves the spread of culture through social interaction and proximity. Hierarchical expansion diffusion is the spread of culture from a dominant core to surrounding areas. Relocation diffusion occurs when people relocate and bring their culture with them, spreading it to a new area. The Maori Haka spread through New Zealand and internationally as the All Blacks rugby team performed it before matches, exposing more people to Maori culture through social interaction and the influence and relocation of All Blacks players.
Antarctica
Antarctica is the southernmost continent, located around the South Pole. It is the coldest, driest, windiest continent and holds 90% of the world's ice and 70% of its fresh water. Antarctica is covered by a vast ice sheet that is on average 7,200 feet thick. If the ice melted, sea levels would rise 230 feet and flood many coastal cities. No permanent human residents live in Antarctica, though about 4,000 scientists reside there seasonally. Several countries have claimed ownership of parts of Antarctica but it is governed by an international treaty.
Zones of the Andes 2014
The document describes the different zones of elevation in the Andes Mountains, from the lowest coastal plains up through the high altitude puna grasslands. It notes that each 1,000 meter increase in elevation brings a change in climate and vegetation, from tropical rainforests near sea level up through dry scrublands and grasslands at higher elevations. Life becomes more difficult for both humans and animals the higher and colder one travels in the Andes.
Weber Notes 2014
This document discusses factors that influence the location of industrial activity, including primary industries locating near resource deposits and secondary industries considering transportation costs of raw materials and finished goods. It summarizes Alfred Weber's least cost theory of industrial location and describes how transportation, labor, infrastructure, energy, agglomeration, and other political and environmental factors affect site selection. Silicon Valley is provided as an example of an industrial agglomeration influenced by proximity to a university, skilled labor, and natural resource abundance.
Economic Sectors
The document describes the five main economic sectors: primary, secondary, tertiary, quaternary, and quinary. The primary sector involves extracting raw materials from the earth. The secondary sector transforms raw materials into finished goods through manufacturing and construction. The tertiary sector provides services to individuals and businesses. The quaternary sector involves knowledge-based and intellectual activities like education, research, and information technology. Finally, the quinary sector involves complex decision-making and management at the highest levels of government, science, and culture.
Geopolitical Theory
Geopolitical theory examines the relationship between geography, politics, and international relations. Key thinkers in geopolitical theory include:
- Alfred Thayer Mahan (1890) who argued that naval power was essential for trade and that countries with long coastlines and access to key sea lanes would be most powerful.
- Halford Mackinder (1904) who developed the heartland theory that whoever controlled the strategically located heartland region of Eurasia would control the world.
- Nicholas Spykman (1940s) argued that the inner crescent region (Western Europe, Middle East, South Asia, Southeast Asia) known as the rimland was most important, as it provided access to both sea and
Political Boundaries UNCLOS
This document discusses several international agreements related to political boundaries:
- UNCLOS III established guidelines for territorial waters, exclusive economic zones, and the continental shelf. It set the territorial limit at 12 nautical miles and the EEZ at 200 miles.
- The Antarctic Treaty designated Antarctica as a scientific preserve to be used for peaceful purposes only. It prohibits nuclear weapons and mining.
- The Kyoto Protocol set binding emissions reduction targets for industrialized countries in an effort to combat climate change. It aimed to reduce emissions of greenhouse gases between 2008-2012 but did not require commitments from developing nations. The US withdrew from the agreement in 2001.

Territorial morphology key 2014
This document discusses concepts related to territorial morphology and boundaries. It defines human territoriality as a country's control over and attachment to its geographic area. Sovereignty refers to a territory's final authority over its political and military affairs. Territorial morphology examines a state's size, shape, and location relative to neighbors, which can impact communication and conflict. The document then analyzes different morphological types such as compact, fragmented, elongated, protruded, and perforated states. It concludes by discussing the nature of boundaries, including different boundary types and common disputes that can arise over boundaries.
Devolution and Supranationalism
Devolution refers to the process where regions within a state gain more autonomy and political power at the expense of the central government, potentially leading to the disintegration of the state along regional lines. Examples include Scotland seeking independence from the UK, the peaceful split of Czechoslovakia in 1993, and the breakup of Yugoslavia into independent states. Supranationalism refers to the formation of unions between three or more states to pursue shared economic, political, and cultural goals for mutual benefit. Current examples of supranational organizations include the European Union, United Nations, NATO, OPEC, and the Arab League.

It defines human territoriality as controlling what happens in a specific geographic area and sovereignty as the final authority over a territory's political and military affairs. It describes territorial morphology as referring to a state's size, shape, and location and how this can impact communication and conflicts with neighbors. It provides examples of different morphological types of states including compact, fragmented, elongated, protruded/prorupt, and perforated states. It also discusses the nature, definitions, delimitations, demarcations, and types of disputes related to boundaries between states.
Geopolitics Key
This document provides an overview of geopolitics, including definitions and perspectives from influential geopolitical theorists. It defines geopolitics as the study of how geographical factors influence politics and international relations. It discusses the work of Friedrich Ratzel, who viewed states as organic organisms that seek to expand, Halford Mackinder, who emphasized the strategic importance of Eurasia, and Nicholas Spykman, who argued that control of the rimland surrounding Eurasia was key to global power rather than the heartland alone.
Devoluation or Supranationalism
Devolution refers to the process where regions within a state gain greater autonomy and political power at the expense of the central government, potentially leading to the disintegration of the state along regional lines. Examples include Scotland seeking independence from the UK, the peaceful split of Czechoslovakia in 1993, and the breakup of Yugoslavia into independent states. Supranationalism refers to the formation of unions between three or more states to pursue shared economic, political, and cultural goals for mutual benefit.

Nationality denotes legal attachment and allegiance to a particular country. Ethnicity, race, and nationality represent different aspects of group identity.
Religion notes 13
This document contains notes on religion from various sources including pages 188-189 and 191 of an unknown text, as well as websites on religion worldwide, Christianity in Europe, Islam in Africa, and the distribution of Hinduism and Buddhism. It also includes notes on major world religions like Christianity, Islam, Hinduism, Buddhism, and Judaism providing statistics on adherents and geographic origins or centers.
Language Presentation 2013
There were originally 7,000-8,000 languages spoken worldwide, but many are becoming extinct, especially in Australia and the Americas. Today there are around 165 languages spoken in the US and 1,000 languages each in Africa and New Guinea. Languages are grouped into families that share a common ancestral language, with the major families including Indo-European from 4,000 years ago and its branches like Germanic. English belongs to the Germanic branch of the Indo-European family and the West Germanic group within that branch. The document also provides information on the evolution of languages over time and definitions of related concepts like dialects, pidgins, lingua francas, and creoles.
Migration Notes 2012
This document discusses several key topics related to human migration including push and pull factors, voluntary vs forced migration, refugees vs asylum seekers, internally displaced persons, and refugee resettlement statistics. It defines refugees according to the 1951 Refugee Convention and notes the top refugee producing countries. It also explains that internally displaced persons differ from refugees in that they have not crossed an international border despite facing similar circumstances like conflict, violence or disasters.
2013 Population Geography College HUG
The document discusses key concepts in population geography, including population density, distribution, growth rates, and statistics. It notes that over half the world's population lives in East, South, and Southeast Asia on less than 10% of the land. Population is concentrated along river valleys and coastal areas, and in many places is experiencing exponential growth and shorter doubling times. Higher birth rates are seen in Africa and Southwest Asia, while death rates are lowest in North America, Europe, and other developed regions.
The five themes of geography 2012
The document outlines the five themes of geography: location, which refers to both absolute and relative location; place, which identifies distinguishing human and physical characteristics such as culture, landforms, and rivers; region, which combines places with similar characteristics; human-environment interaction, which examines how humans adapt to, modify, and depend on the environment; and movement, which refers to the movement of people, goods, and ideas both locally and globally.
Zones of the andes 2013
The document describes the different zones of elevation in the Andes Mountains, from the lowest coastal plains up through the high altitude puna grasslands and rocky deserts. It notes that each 1,000 meter increase in elevation brings a change in climate and vegetation, from tropical rainforests near sea level to freezing temperatures and permanent snow above 5,000 meters. Life in the Andes has adapted to these varied zones over thousands of years.
Weber notes 2013
This document discusses Weber and industrial location theory. It explains that Weber's location theory sought to explain why industries locate where they do based on factors like transportation costs of moving raw materials and finished goods, availability of labor, and agglomeration effects. While influential, critics argued Weber's model did not fully account for variations in these costs over time or factors like taxation. The document then examines how transportation access, available labor supply, infrastructure, energy access, and agglomeration continue to influence industrial location decisions.
Diffusion
This document defines cultural diffusion as the process by which cultural characteristics spread across space over time. It identifies two main types of diffusion: expansion diffusion, where an idea develops in one place and spreads outward while remaining strong in the source area; and relocation diffusion, where an idea spreads through the physical movement of people from one place to another. The document provides examples of different patterns of expansion diffusion, including hierarchical, contagious, and stimulus diffusion.
Types of diffusion
Diffusion is the process by which something spreads from one place or individual to others. The document discusses three main types of diffusion: expansion diffusion which occurs when something spreads from one core location to others nearby in a hierarchical, contagious, or stimulus-driven manner, and relocation diffusion which involves the movement of people or ideas over longer distances.
New providence
New Providence has undergone significant changes to its cityscape. The capital and largest city of the Bahamas, Nassau on New Providence, has seen many developments that have transformed the look and feel of the city. New high-rise buildings, hotels, and commercial centers have gone up, altering the skyline and adding modern architecture to the historic city.
Central Place Theory
Central Place Theory proposes that settlements function as market centers that provide goods and services to surrounding hinterlands. The hierarchy and distribution of settlements is based on their functions and the distances people will travel. Larger central places with more services are farther apart and include the hinterlands of smaller places. The theory uses hexagonal tessellation and assumptions about uniform landscapes to model how central places are spatially arranged. While a simplification, the central place model explains real hierarchies and relationships between human settlements.
Geopolitical theory
Geopolitics is the study of how geographical factors like territory, population, resources, and location influence international politics and relations between states. Key thinkers in geopolitical theory include Alfred Thayer Mahan who argued sea power was essential for trade and power, Halford Mackinder who developed the Heartland Theory that control of the Eurasian core landmass meant control of the world, and Nicholas Spykman who argued control of the rimlands of Europe and Asia was more important than the heartland. Immanuel Wallerstein viewed the global political economy as consisting of core states that exploited peripheral states, with semi-peripheral states acting as buffers between them.
Measures of development_ppt
This document discusses concepts related to economic development, including factors that determine development levels, characteristics of less developed and developed countries, and methods for measuring development. It presents several models of development, including Rostow's stages of growth model and dependency theory. Key points include: resources, population, location, and colonial status influence development; less developed countries have lower incomes, subsistence farming, and poorer social conditions compared to developed countries with higher incomes, manufacturing/services, and better social conditions; development is commonly measured using GDP per capita, rates like literacy, and occupational structure; and the core-periphery model and dependency theory argue regional disparities are structural features of the global economy.

GASTROINTESTINAL INFECTIONS AND GASTRITIS
Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort. More Related Content
