Cultural Diffusion in Anthropology
Words • 324
Pages • 2
Diffusion generally refers to the transplanting of cultural aspects from one group to another. That is, the music, political ideologies, fashion, and any variety of items/beliefs/cultural identities appeal cross from one group to another. While some may consider this a profound concept, the reality is that cultural diffusion is not something that is new and has existed for many centuries. In many cases, diffusion is benign and rooted in popular culture and a desire to experience of discover something new.…...

Diffusion of New Products in Social Networks
Words • 442
Pages • 2
Consumers' increasing distrust in traditional advertising (Chalmers, 2017; Lee, 2012) has led them to rely more on reviews from prior buyers connected with them in social networks to learn about new products' characteristics. This consumers' new reliance on social networks has encouraged researchers to i) include consumer-level interactions in social networks to study new products' life-cycle, and ii) exploit information about how consumers are connected in a network to design marketing strategies for new products.Early literature on diffusion of new…...

Pages • 6
A sampling of the water column and benthos was carried out at Mission Bay. Water column and plankton sampling was conducted biweekly while Sediment and benthic community samples were collected monthly. Particle size, porosity, and the initial phosphorus concentration in sediments are the main factors affecting phosphorus release flux through the sediment-water interface. Sediments can be physically divided to muddy and sandy matters, and the adsorption-desorption capacity of sediment with phosphorus depends on particle size. Pollutants' interaction with water and…...

Passive and Active Cell Transport Mechanisms
Words • 2169
Pages • 8
The cell is invaluable building block of all biological life on this planet, and one of its most important and unique characteristics is its ability to be selectively permeable with its plasma membrane. This outer membrane’s sophisticated mechanisms of transport through its bilayer are vital in maintaining homeostasis in the cell and the entire body. To further understand these mechanisms, which can be further described as passive and active transport, five experiments were conducted. These tests were done over simple…...

Kinetic energy, a root of energy stored in cells, causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water likely. Water potential…...
Cell Transport
Words • 684
Pages • 3
There are two types of cell transport mechanisms. These types of transports are passive and active transport. The difference between active and passive is that passive does not require energy and active does require energy. The reason passive does not require energy is because it travels down a concentration gradient. On a concentration gradient molecules naturally move from high to low concentration. In active transport, molecules move from low to high concentration. There are three different types of transports for…...
Cultural Diffusion in Different Cultures

Pages • 9
Cultural Diffusion is the process by which a cultural trait, material objects, idea or behavior pattern is spread from one society to another. It is very common in ancient times when small groups of humans lived in adjoining settlements and spreading of ideas and culture occurs. Since cultures have never been completely isolated from each other, diffusion has happened through out history and continues on today. Mesopotamia, considered as a place where civilization begins, was destined to be a land…...

Words • 658
Pages • 3
Introduction Diffusion is movement of molecules from one area of concentration to another. This process is vital for the life functions of cells. Cells have selectively permeable membranes that allow only certain solutions to pass through them. Osmosis is a special kind of diffusion that allows water to go through semi-permeable membranes of high water potential to a region of lower water potential. Water potential measures the tendency of water to leave one place and into another. Diffusion and osmosis…...
