Human Migration
Human migration is the movement of people from one place to another with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is also possible; indeed, this is the dominant form of human migration globally. Migration is often associated with better human capital at both individual and household level, and with better access to migration networks, facilitating a possible second move. It has a high potential to improve human development, and some studies confirm that migration is the most direct route out of poverty.Age is also important for both work and non-work migration. People may migrate as individuals, in family units or in large groups. There are four major forms of migration: invasion, conquest, colonization and emigration/immigration. Persons moving from their home due to forced displa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Migration (Bonobo Album)
''Migration'' is the sixth studio album by British DJ and record producer Simon Green, performing under the name Bonobo. It was released on 13 January 2017. Background ''Migration'' was primarily written and recorded while Green was still on tour for his previous album, '' The North Borders''. After the completion of the tour, Green completed a move from New York City to the Echo Park neighborhood of Los Angeles. The move, as well as the travelling for the tour and the deaths of some family members, led Green to contemplate on themes of identity, migration, and the environment. Because the tour for ''The North Borders'' consisted of approximately 175 shows across three continents for about eighteen months, the music for ''Migration'' was mainly created on a laptop as opposed to the studio environments of Green's previous albums. Artwork Neil Krug served as the art director for the album. Green had tasked Krug to create artwork that was "beautifully sinister". Krug and Green ...

Animal Migration
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. The cause of migration may be local climate, local availability of food, the season of the year or for mating. To be counted as a true migration, and not just a local dispersal or irruption, the movement of the animals should be an annual or seasonal occurrence, or a major habitat change as part of their life. An annual event could include Northern Hemisphere birds migrating south for the winter, or wildebeest migrating annually for seasonal grazing. A major habitat change could include young Atlantic salmon or sea lamprey leaving the river of their birth when they have reached a few inches in size. Some traditional forms of human migration fit this pattern. Migrations can be studied using traditi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale The Summit Discography
This is the discography of Scale the Summit, an instrumental progressive metal band from Houston, Texas. Formed in 2004, Scale the Summit have released six studio albums, one single and one demo. Scale the Summit was formed in 2004 by guitarist Chris Letchford and some classmates from the Los Angeles Musicians Institute. Their debut album, ''Monument'', was self-funded and self-released, but the group signed to Prosthetic Records in time to release their second album, ''Carving Desert Canyons''. After the release of ''The Collective'', the group's third record and last to feature their original lineup, the band finally headlined their own tour in 2012, having been a supporting act on all tours up to that point. The following year, the band released ''The Migration'', the first to feature a new member in place of an original member, and two years later another original member left before the release of their fifth album ''V''. ''Monument'' ''Monument'', the band's debut album, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Migration
International migration occurs when people cross state boundaries and stay in the host state for some minimum length of the time. Migration occurs for many reasons. Many people leave their home countries in order to look for economic opportunities in another country. Others migrate to be with family members who have migrated or because of political conditions in their countries. Education is another reason for international migration, as students pursue their studies abroad, although this migration is often temporary, with a return to the home country after the studies are completed. Categories of migrants While there are several different potential systems for categorising international migrants, one system organizes them into nine groups: * temporary labor migrants *irregular, illegal, or undocumented migrants *highly skilled and business migrants *refugees *asylum seekers *forced migration *family members * return migrants *long-term, low-skilled migrants These migrants can al ...

Data Migration
Data migration is the process of selecting, preparing, extracting, and transforming data and permanently transferring it from one computer storage system to another. Additionally, the validation of migrated data for completeness and the decommissioning of legacy data storage are considered part of the entire data migration process. Data migration is a key consideration for any system implementation, upgrade, or consolidation, and it is typically performed in such a way as to be as automated as possible, freeing up human resources from tedious tasks. Data migration occurs for a variety of reasons, including server or storage equipment replacements, maintenance or upgrades, application migration, website consolidation, disaster recovery, and data center relocation. The standard phases , "nearly 40 percent of data migration projects were over time, over budget, or failed entirely." As such, to achieve an effective data migration, proper planning is critical.

Seismic Migration
Seismic migration is the process by which seismic events are geometrically re-located in either space or time to the location the event occurred in the subsurface rather than the location that it was recorded at the surface, thereby creating a more accurate image of the subsurface. This process is necessary to overcome the limitations of geophysical methods imposed by areas of complex geology, such as: faults, salt bodies, folding, etc. Migration moves dipping reflectors to their true subsurface positions and collapses diffractions, resulting in a migrated image that typically has an increased spatial resolution and resolves areas of complex geology much better than non-migrated images. A form of migration is one of the standard data processing techniques for reflection-based geophysical methods (seismic reflection and ground-penetrating radar) The need for migration has been understood since the beginnings of seismic exploration and the very first seismic reflection data from ...

Cell Migration
Cell migration is a central process in the development and maintenance of multicellular organisms. Tissue formation during embryonic development, wound healing and immune responses all require the orchestrated movement of cells in particular directions to specific locations. Cells often migrate in response to specific external signals, including chemical signals and mechanical signals. Errors during this process have serious consequences, including intellectual disability, vascular disease, tumor formation and metastasis. An understanding of the mechanism by which cells migrate may lead to the development of novel therapeutic strategies for controlling, for example, invasive tumour cells. Due to the highly viscous environment (low Reynolds number), cells need to continuously produce forces in order to move. Cells achieve active movement by very different mechanisms. Many less complex prokaryotic organisms (and sperm cells) use flagella or cilia to propel themselves. Eukaryot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Migration
Legacy modernization, also known as software modernization or platform modernization, refers to the conversion, rewriting or porting of a legacy system to modern computer programming languages, architectures (e.g. microservices), software libraries, protocols or hardware platforms. Legacy transformation aims to retain and extend the value of the legacy investment through migration to new platforms to benefit from the advantage of the new technologies.Gardner, D"Not just a nip and tuck, application modernization extends the lifecycle of legacy code assets" ''ZDNet'', October 24, 2006 As a basis and first step of software modernization initiatives, the strategy, the risk management, the estimation of costs, and its implementation, lies the knowledge of the system being modernized.

Migration (ecology)
Migration, in ecology, is the large-scale movement of members of a species to a different environment. Migration is a natural behavior and component of the life cycle of many species of mobile organisms, not limited to animals, though animal migration is the best known type. Migration is often cyclical, frequently occurring on a seasonal basis, and in some cases on a daily basis. Species migrate to take advantage of more favorable conditions with respect to food availability, safety from predation, mating opportunity, or other environmental factors. While members of some species learn a migratory route on their first journey with older members of their group, other species genetically pass on information regarding their migratory paths. Despite many differences in organisms’ migratory cues and behaviors, “considerable similarities appear to exist in the cues involved in the different phases of migration.” Migratory organisms use environmental cues like photoperiod and weat ...
