The Aleut Corporation , or TAC , is one of thirteen Alaska Native Regional Corporations created under the Alaska Native Claims Settlement Act of 1971 (ANCSA) in settlement of aboriginal land claims. The Aleut Corporation was incorporated in Alaska on June 21, 1972. Headquartered in Anchorage, Alaska , The Aleut Corporation is a for-profit corporation with approximately 3,410 Alaska Native shareholders, primarily of Aleut descent originating in the Alaska Peninsula , Aleutian Islands , Pribilof Islands , and Shumagin Islands of Alaska.

Its land entitlement included 66,000 acres (270 km) of surface lands and 1.572 million acres (6,362 km) of subsurface estate. A current listing of The Aleut Corporations' officers and directors, as well as documents filed with the State of Alaska since TAC's incorporation, are available online through the Corporations Database of
158-516: A Superfund to remediate abandoned sites, or to litigate to force corporations to remediate their contaminated sites. Other countries have other mechanisms and commonly sites are rezoned to "higher" uses such as high density housing, to give the land a higher value so that after deducting cleanup costs there is still an incentive for a developer to purchase the land, clean it up, redevelop it and sell it on, often as apartments (home units). There are several tools for mapping these sites and which allow

Compliance must be cheaper than to have continuous breaches. Assessment should be made of the risks of operations, transporting contaminated material, disposal of waste which may be contaminated including workers' clothes, and a formal emergency response plan should be developed. Every worker and visitor entering

Henry Mintzberg described five definitions of strategy in 1998: Complexity theorists define strategy as the unfolding of the internal and external aspects of
395-450: A chemical free technology. Air microbubbles generated in water without adding any surfactant could be used to clean oil contaminated sediments. This technology holds promise over the use of chemicals (mainly surfactant) for traditional washing of oil contaminated sediments. In preparation for any significant remediation there should be extensive community consultation. The proponent should both present information to and seek information from
474-571: A concentration of 93% and bioaccumulation factor of 5.6, lead , mercury , zinc with a bioaccumulation factor of 3.6, and arsenic at a concentration of 22%. Black soldier fly larvae (BSFL) have also been used to monitor the degradation and reduction of anthropogenic oil contamination in the environment. Entomoremediation is considered viable as an accessible low-energy, low-carbon, and highly renewable method for environmental decontamination. Cleaning of oil contaminated sediments with self collapsing air microbubbles have been recently explored as
553-636: A conceptual framework capable of harmonizing emergent and deliberate strategies. Within complexity approaches, the term "strategy" is intricately linked to action but contrasts programmed action. Complexity theorists view programs merely as predetermined sequences effective in highly ordered and less chaotic environments. Conversely, strategy emerges from a simultaneous examination of determined conditions (order) and uncertainties (disorder) that drive action. Complexity theory posits that strategy involves execution, encompasses control and emergence, scrutinizes both internal and external organizational aspects, and can take
632-635: A doctrine that will ensure long-term success if followed faithfully." Subordinating the political point of view to the military would be absurd, for it is policy that has created war...Policy is the guiding intelligence, and war only the instrument, not vice-versa. In military theory, strategy is "the utilization during both peace and war, of all of the nation's forces, through large scale, long-range planning and development, to ensure security and victory" ( Random House Dictionary ). The father of Western modern strategic study , Carl von Clausewitz , defined military strategy as "the employment of battles to gain

Most field applications of nanoremediation have used nano zero-valent iron (nZVI), which may be emulsified or mixed with another metal to enhance dispersion. That nanoparticles are highly reactive can mean that they rapidly clump together or react with soil particles or other material in the environment, limiting their dispersal to target contaminants. Some of

The use of incremental health risk is based on carcinogenic and other (e.g., mutagenic , teratogenic ) effects and often involves value judgements about the acceptable projected rate of increase in cancer . In some jurisdictions this is 1 in 1,000,000 but in other jurisdictions the acceptable projected rate of increase is 1 in 100,000. A relatively small incremental health risk from
1027-605: A set of attraction basins establishing operational and regenerative capabilities. Hence, one of the primary roles of strategists is to identify "human attractors" and assess their impacts on organizational dynamics. According to the theory of Symbiotic Dynamics, both leaders and the technical system can act as attractors, directly influencing organizational dynamics and responses to external disruptions. Terra and Passador further assert that while producing, organizations contribute to environmental entropy, potentially leading to abrupt ruptures and collapses within their subsystems, even within
1106-459: A single project is not of much comfort if the area already has a relatively high health risk from other operations like incinerators or other emissions, or if other projects exist at the same time causing a greater cumulative risk or an unacceptably high total risk. An analogy often used by remediators is to compare the risk of the remediation on nearby residents to the risks of death through car accidents or tobacco smoking . Standards are set for
1185-555: A strategic problem. The first is related to environmental factors, and the second focuses on the organizational context (Mukherji and Hurtado, 2001). These two sources summarize three dimensions originally proposed by Ansoff and Hayes (1981). According to them, a strategic problem arises from analysis of internal and external issues, the processes to solve them, and the variables involved. In Terra and Passador's conceptualization, organizations and their surrounding systems are closely linked, so their survival depends on each other. Therefore,
1264-479: A strategy should combine proactive and reactive approaches, which means recognizing the organization’s impact on the environment and acting to minimize harm while adapting to new demands. The strategy should also align internal and external aspects of the organization and include all related entities. This helps build a complex socio-economic system where the organization is part of a sustainable ecosystem. Complexity science, as articulated by R. D. Stacey, represents

During the process a desorber volatilizes the contaminants (e.g. oil, mercury or hydrocarbon) to separate them from especially soil or sludge. After that the contaminants can either be collected or destroyed in an offgas treatment system. Excavation processes can be as simple as hauling the contaminated soil to a regulated landfill , but can also involve aerating

The use of slurry walls is well-established in the construction industry. The application of (low) pressure grouting , used to mitigate soil liquefaction risks in San Francisco and other earthquake zones, has achieved mixed results in field tests to create barriers, and site-specific results depend upon many variable conditions that can greatly impact outcomes. Remedial action

Environmental remediation Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil , groundwater , sediment . Remediation may be required by regulations before development of land revitalization projects. Developers who agree to voluntary cleanup may be offered incentives under state or municipal programs like New York State's Brownfield Cleanup Program. If remediation

Barrier walls must be constructed of impermeable materials and resistant to deterioration from contact with waste, for
3397-516: The United Kingdom's counterterrorism strategy, CONTEST , seeks "to reduce the risk to the UK and its citizens and interests overseas from terrorism, so that people can go about their lives freely and with confidence." The essence of formulating competitive strategy is relating a company to its environment. Modern business strategy emerged as a field of study and practice in the 1960s; prior to that time,
3476-426: The basic requirements for strategy development include, among other factors: 1) extensive knowledge about the environment, market and competitors; 2) ability to examine this knowledge as an interactive dynamic system; and 3) the imagination and logic to choose between specific alternatives. Henderson wrote that strategy was valuable because of: "finite resources, uncertainty about an adversary's capability and intentions;

The nanomaterials then degrade organic contaminants through redox reactions or adsorb to and immobilize metals such as lead or arsenic . In commercial settings, this technology has been dominantly applied to groundwater remediation , with research into wastewater treatment . Research is also investigating how nanoparticles may be applied to cleanup of soil and gases. Nanomaterials are highly reactive because of their high surface area per unit mass, and due to this reactivity nanomaterials may react with target contaminants at
3871-495: The contaminants from the groundwater. For petroleum-contaminated sites this material is usually activated carbon in granular form. Chemical reagents such as flocculants followed by sand filters may also be used to decrease the contamination of groundwater. Air stripping is a method that can be effective for volatile pollutants such as BTEX compounds found in gasoline. For most biodegradable materials like BTEX , MTBE and most hydrocarbons, bioreactors can be used to clean
3950-442: The contaminated water to non-detectable levels. With fluidized bed bioreactors it is possible to achieve very low discharge concentrations which will meet or exceed discharge requirements for most pollutants. Depending on geology and soil type, pump and treat may be a good method to quickly reduce high concentrations of pollutants. It is more difficult to reach sufficiently low concentrations to satisfy remediation standards, due to
4029-587: The degradation of the target pollutants. Broad categories of bioremediation include biostimulation , bioaugmentation , and natural recovery ( natural attenuation ). Bioremediation is either done on the contaminated site (in situ) or after the removal of contaminated soils at another more controlled site (ex situ). In the past, it has been difficult to turn to bioremediation as an implemented policy solution, as lack of adequate production of remediating microbes led to little options for implementation. Those that manufacture microbes for bioremediation must be approved by

4345-446: The end of war." B. H. Liddell Hart 's definition put less emphasis on battles, defining strategy as "the art of distributing and applying military means to fulfill the ends of policy". Hence, both gave the pre-eminence to political aims over military goals. U.S. Naval War College instructor Andrew Wilson defined strategy as the "process by which political purpose is translated into military action." Lawrence Freedman defined strategy as
4424-413: The environment or situation, making a diagnosis, and developing guiding policies. It includes such activities as strategic planning and strategic thinking . Implementation refers to the action plans taken to achieve the goals established by the guiding policy. Bruce Henderson wrote in 1981 that: "Strategy depends upon the ability to foresee future consequences of present initiatives." He wrote that
4503-546: The equilibrium of absorption / desorption processes in the soil. However, pump and treat is typically not the best form of remediation. It is expensive to treat the groundwater, and typically is a very slow process to clean up a release with pump and treat. It is best suited to control the hydraulic gradient and keep a release from spreading further. Better options of in-situ treatment often include air sparge/soil vapor extraction (AS/SVE) or dual phase extraction/multiphase extraction (DPE/MPE). Other methods include trying to increase

This author applied self-organization and chaos principles to describe strategy, organizational change dynamics, and learning. Their propositions advocate for strategy approached through choices and the evolutionary process of competitive selection. In this context, corrections of anomalies occur through actions involving negative feedback, while innovation and continuous change stem from actions guided by positive feedback. Dynamically, complexity in strategic management can be elucidated through

Strategy can be intended or can emerge as a pattern of activity as the organization adapts to its environment or competes. It involves activities such as strategic planning and strategic thinking . Henry Mintzberg from McGill University defined strategy as
4819-573: The groundwater may also cause contamination to spread faster than normal depending on the hydrogeology of the site. In these cases, injections downgradient of groundwater flow may provide adequate microbial destruction of contaminants prior to exposure to surface waters or drinking water supply wells. Migration of metal contaminants must also be considered whenever modifying subsurface oxidation-reduction potential. Certain metals are more soluble in oxidizing environments while others are more mobile in reducing environments. Soil vapor extraction (SVE)
