A biome is a large geographical area defined by similar climate and abiotic factors that support dominant plants and animals. Key abiotic factors that define biomes include precipitation, latitude and radiant energy, altitude, geography and landforms, and soil type and composition. These non-living environmental conditions determine what types of plants and animals are able to survive within each biome.

Succession and soil formation
Succession is the process by which one ecological community replaces another over time. There are two main types: primary succession, which occurs on new surfaces like bare rock, and secondary succession, which follows a disturbance of an existing community. Pioneer plants are the first to colonize an area during succession, helping to form soil. Over time, the community develops into a climax community that maintains a stable population. Succession can be driven by natural disturbances or human activities that open up space for new plants and animals to establish themselves.

Storytelling Is Not Enough IGNITE
Slides for an IGNITE talk about a couple of other big ideas in education beyond storytelling. Based in large part on a talk given by Alan Kay called Powerful Ideas Need Love Too.
Social media & informed learning
Academic libraries can connect with users by joining different initiatives ("dots") together. The presentation discusses how libraries can join initiatives in areas like makerspaces, data services, and community outreach. Images included show examples of libraries involved in activities like 3D printing, data visualization, and hosting community events. Connecting initiatives helps libraries stay relevant by engaging with modern topics and community needs.
Social Media and Opportunity for Psychiatrists
Social media presents opportunities for psychiatrists to engage in sharing, open interaction, and relationship building, but it also raises concerns around identity, control, privacy, and professional boundaries. Effective use of social media requires psychiatrists to thoughtfully consider how their online presence and values align across domains of identity, relationships, power, trust, and context. While social media allows for greater connection, it also takes time and risks fears around professionalism, so psychiatrists must carefully weigh these factors in determining their approach.

Keynote presentation for ITC 2011 ( February 20, 2011, St Petersburg FL)
In our media soaked culture, thé cliche exchange rate of 1000 words per picture seems quite low. The mechanics and art of photography unveil an intriguing metaphor for thinking about learning. For a photographer, the operation of cameras-- exploiting apertures, shutter speeds, optics, filters-- coexist with the artistic skills of pre-visualization, framing, composition. We meld with the camera, the boundary between tools and our human capabilities blur.
Taking the metaphor farther, creating an engaging learning experience is much more than point and shoot. Few successful photographers are born innately with their skills- it is a craft, as is learning, that often improves in the act of doing, trying, and reflecting.

The mechanics and art of photography unveil an intriguing metaphor for thinking about learning and our world view. For a photographer, the operation of cameras-- exploiting apertures, shutter speeds, optics, -- coexist with the artistic skills of pre-visualization, framing, composition. It is no longer a field dominated by pros with expensive gear, we can all make photographic art.
Taking the metaphor farther, creating an engaging learning experience is much more than point and shoot or flipping the settings into automatic mode. Photography is a beautiful example of how you can get better at doing something just by regularly doing (and sharing) your craft. Regular acts of photography, such as the Daily Create, are a model of informal learning that works.
Do libraries have a future?
The document discusses the future of libraries and whether they will continue to be relevant. It touches on the fragmentation of information sources and whether libraries can help defragment information. The role of libraries as community spaces for sharing information and stories is explored, with some analogizing modern libraries to secular cathedrals or abbeys. The conclusion raises the question of whether libraries may architect their own destruction if they do not adapt to changing information needs and technologies.

5 Sales Prospecting Techniques You Probably Never Tried (but Should).
When I recently reached out to my network and asked "What is the #1 challenge you are facing when it comes to growing sales for your business ?" 75% of those I asked mentioned sales prospecting or lead generation.
The problem isn't that people don't know what do to; it's that what they've always done no longer works.
The simple truth is: if you're doing what everybody else is doing, you'll get the same results they do. Which - in a world where prospects are increasingly turning off their phone and turning *on* their spam filters - isn't much.
So if you want to stand out (and get more meetings), here are five sales prospecting techniques you probably never tried (but should).

This document discusses how repositories can engage audiences and users through social media. It suggests that repositories should prominently feature sharing options to encourage dissemination of content. Repository staff should act as ambassadors by being the first to share great research content. Repositories also need to identify their audiences and understand how to engage them where they socialize online. Combining repository data with social media mentions and profiles could provide opportunities to track impact and suggest future collaborations.

Ecosystems intro - December 2010
Ecosystems consist of communities of living things that interact not only with each other, but also with non-living elements of their environment. An ecosystem is defined as an area where a biological community interacts with the surrounding physical environment. The two main components of an ecosystem are the biotic factors, consisting of living things, and abiotic factors, consisting of non-living elements. Matter cycles through both biotic and abiotic elements in ecosystem biogeochemical cycles, such as the water cycle which involves evaporation, condensation, transpiration, precipitation, infiltration, discharge and storage.
Soil
Soil is composed of distinct horizontal layers called horizons that range from rich organic layers on top to underlying rocky layers. The top organic O horizon contains leaf litter and humus, while the A horizon below is dark topsoil containing humus and minerals. Below this is the E horizon which has lost minerals and clay, followed by the B subsoil horizon containing clay and mineral deposits received from above layers, and finally the C regolith and underlying R bedrock layers with few roots and organic material.

Ac act
This document outlines the Arbitration and Conciliation Act of 1996 in India, which consolidates and amends laws related to domestic and international commercial arbitration. It was enacted to align Indian law with the UNCITRAL Model Law on International Commercial Arbitration and UNCITRAL Conciliation Rules. The Act aims to provide a unified legal framework for the fair and efficient settlement of disputes arising in international commercial relations. It extends arbitration and conciliation laws to both domestic and international commercial disputes in India.
Easement act
The document defines and discusses different types of easements and licenses related to land ownership. It covers:
1) An easement is a right to use another's land for a specific purpose. Easements can be continuous or discontinuous, apparent or non-apparent.
2) An easement can be extinguished, or ended, in several ways, including by release or revocation by the landowner, expiration of time limits, or non-use for 20 years.
3) A license is permission to do something that would otherwise be unlawful, but does not transfer ownership rights. Licenses can be revoked by the grantor unless work was done or expenses incurred in reliance on the license.

The document discusses forces acting on several objects: the space shuttle experiences gravity, thrust, drag and lift as it launches into space; a car feels gravity, normal force from the road, and friction which can cause traction or skidding depending on its speed around a corner; a sailboat is pushed across water through the force of wind pressing against its sails.
Homeostasis
The document discusses homeostasis and thermoregulation through a series of diagrams and explanations. It begins by defining homeostasis as the property of a system to maintain stable internal conditions despite external changes. It then explains how thermoregulation works through receptors that detect blood temperature and skin temperature, a control center in the hypothalamus, and effectors like sweating and shivering that act to cool or warm the body. The document uses examples of thermoregulation, blood sugar regulation, and water balance in the kangaroo rat to illustrate the general components and mechanisms of homeostasis.

The document discusses how the Resource Description and Access (RDA) cataloguing standard will impact the future cataloguing community. RDA aims to provide a more flexible approach to metadata creation that aligns with the digital environment. This may require cataloguers to learn new skills and standards that are more compatible with linked data. The transition to RDA presents both opportunities and challenges for the cataloguing community.

Scientific method
The document outlines the basic steps of the scientific method, using Louis Pasteur's experiment on bacterial growth as an example. It discusses the key components of an experiment, including manipulated, controlled, and responding variables. Pasteur's experiment aimed to test his hypothesis that airborne particles caused bacterial growth in broth by preventing or allowing air to reach sterilized broth samples. The results supported his hypothesis, as bacterial growth only occurred in samples exposed to air. This experimentation contributed to the development of the broader theory of germ theory.
Cell theory sept 2010
The document discusses the history of theories about the origin of life, from early ideas of spontaneous generation to the development of cell theory. It describes key experiments by Redi, Spallanzani, and Pasteur that disproved spontaneous generation by showing that living organisms arise only from other living organisms of the same kind. The development of microscopes allowed the discovery of cells, providing evidence that all living things are made of cells or cell products, leading to the modern cell theory.
Natural selection as theory
Natural selection is a good scientific theory because it explains observed phenomena such as how organisms adapt to their environments over generations, makes predictions about what types of traits will help organisms survive and reproduce, and can be scientifically tested by experiments and observations of nature.
Introsoil
Soil is formed from weathered rock and organic matter over long periods of time. It is composed of mineral particles from parent rock along with decayed plant and animal remains. Soil formation involves interactions between air, water, plants, animals, rocks, and chemicals that break down rock into smaller pieces that are mixed into the soil layer. Soil has a profile of distinct horizontal layers called horizons including topsoil, subsoil, and underlying bedrock that vary in composition and provide habitat for plant roots and microbes.
Habitat and niche
The document discusses habitat and niche. It defines habitat as the place where a population lives, obtains resources, and reproduces. Niche is defined as the set of interactions a population has within its community, including its role as a predator, prey, or through commensal/mutualistic relationships. A population's niche may also include its habitat, activity periods, and no two populations can occupy the same niche.
Food webs
The document discusses food webs and their complexity. It notes that food chains oversimplify predator-prey relationships, as most organisms have multiple prey and predator species. A food web shows the multiple interconnected food chains within an ecological community. Some food webs, called grazing webs, begin with plants, while others called detrital webs begin with dead organic matter. There is often overlap between grazing and detrital webs. The stability of food webs depends on the number of species and links between them - webs with more complexity are less vulnerable to collapse from the removal of one species. Keystone species that greatly impact community structure if removed.

Examples like the barrier reef anemonefish, western spadefoot toad, komodo dragon, emperor penguin and blue whale are highlighted. The document concludes by discussing primates and humans, noting our large brains, bipedalism, tool use, and other distinguishing features.
Cell theory 2 (pasteur)
Louis Pasteur conducted experiments using swan-necked flasks that disproved the theory of spontaneous generation and supported the cell theory. Through his experiments, Pasteur showed that broth remained clear if no airborne particles could enter the flask, but would become cloudy if the flask was broken and dust entered, demonstrating that life arises only from pre-existing life and not from non-living matter. Pasteur's findings provided strong evidence for the cell theory that all living things are made of cells that only arise from pre-existing cells.
Cell Theory 1
The document lists several key characteristics of living things: they grow, use energy, are made of cells, can die, require nutrients, exchange gases with their environment, move, depend on other living things, and reproduce. It also notes that living things need water. These characteristics provide a definition of what constitutes a living thing.
