Digital Transformation in Work Integration Social Enterprises: Leadership Strategies and the Role of Internal Stakeholders

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Digital transformation is increasingly reshaping how social enterprises organize work, engage stakeholders, and pursue social value. While prior research has examined digitalization in hybrid organizations, limited attention has been paid to how responsibility for inclusive digital transformation is enacted internally.

PHOTOGRAMMETRIC SURVEY OF OPEN PIT MINE

Contemporary Theory and Practice in Construction, 2017
<jats:p>There is a geodetic department in Ugljevik Coal Mine. In addition to all tasks(expropriation, geometry control of existing engineering objects, monitoring oflandslides, etc.), the primary task of the geodetic service is to calculate the volume of theexcavated masses on a surface mine during a certain period of ...

Failure characteristics and the energy criterion of rock with a through‐going joint under true‐triaxial unloading conditions: Insights from the DEM model

Deep Underground Science and Engineering, EarlyView.
The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

Failure characteristics analysis of the inclined interlayer during water‐soluble cavity construction of underground salt caverns for large‐scale energy storage

Deep Underground Science and Engineering, EarlyView.
In the process of water‐soluble cavern construction of salt cavern energy storage, since the interlayer does not dissolve in water easily, sudden collapse will cause engineering accidents such as bending and damage of the inner tube of the cavern.
