The purpose of this exploratory research is to understand how women have accessed male-dominated oil and gas international rotational assignments and why they believe these roles to be professionally worthwhile.

This cross-sectional qualitative study is based on semi-structured interviews and correspondence with female international rotational assignees, and interviews with HR professionals involved in selection and deployment for such assignments.

HR personnel stereotype women as unsuitable for international rotational assignments. Women must be exceptionally determined and/or circumvent selection processes to access such roles. Women value the professional and personal development gained from international rotational assignments which helps them widen their occupational skills capacity.

To extend these findings, larger samples of female international rotational assignees and research in a wider range of industries are required. Longitudinal studies could further our understanding of women’s career progression building upon their international rotational assignment experience.

To reduce stereotyping of women's perceived unsuitability, greater understanding of international rotational assignment roles/environments is required by managers involved in selection. Transparent selection processes are required to support diversity. Greater interest in the work performed by international rotational assignees will raise their profile and assist with wider labour market opportunities.

Organisational representatives unintentionally reinforce occupational segregation by stereotyping women as less appropriate workers than men for international rotational assignments.

This research hears women's voices as they begin to make inroads into the masculine world of oil and gas international rotational assignments. Research propositions and recommendations for practice are suggested to assist in breaking down male monopoly in this context.

The majority of the previous research on hot spots policing focuses on a single set of relatively small selected experimental areas. However, given limited resources, most law enforcement agencies dispatch hot spots intervention units to several areas on a rotation basis. The purpose of this paper is to examine policing activities in hot spots to determine if the various types of crimes were affected when deployment was applied on a rotation basis.

This study uses data from the Dallas Police Department. The differential influence of police activities, including stops, citations, and arrests, are observed against a number of aggregate crime measures (i.e. violent, property, nuisance offenses, and total index crimes). The impact of police activities have been observed for their immediate and lagged effects during the following week to measure residual deterrence effects.

It was found that the DPD's Disruption Unit's hot spots policing immediately affected violent crimes, nuisance offenses, and total index crimes, while there were no residual effects of hot spots policing. The Disruption Unit was engaged in policing activities that include motor vehicle and pedestrian stops, issuing citations, and making arrests. Among these activities, the number of police stops was the most significant factor for the reduction in violent crime and nuisance offenses.

The researchers use a patrol sector as a unit of analysis in order to compare the influence of various types of police activities on crime across a broader area. Future research should consider using an intermediate geographic unit of analysis (e.g. patrol beat).

The paper examines the differential influence of policing activities on different types of crime around hot spots when deployment was applied on a rotation basis. Both immediate and lagged effects were investigated to find residual deterrence effects of hot spots policing.

The purpose of this paper is to propose an efficient finite element formulation for nonlinear analysis of clustered tensegrity that consists of classical cables, clustered cables and bars.

The derivation of the finite element formulation is based on the co-rotational approach, which decomposes a geometrically nonlinear deformation into a large rigid body motion and a small-strain deformation. A tangent stiffness matrix of a clustered cable is proposed and the Newton-Raphson scheme is employed to solve the nonlinear equation.

The derived tangent stiffness matrix, including an additional stiffness terms that describes the slide effect of pulleys, can regress to the stiffness matrix of a classical cable, which is convenient for the implementation of finite element procedure. Two typical numerical examples show that the proposed formulation is accurate and requires less iteration than the force density method.

The co-rotational formulation of a clustered cable is originally proposed, although some mature methods, such as the TL, Force Density and Dynamic Relaxation method, have been applied to nonlinear analysis of clustered tensegrity. The proposed co-rotational formulation proved efficient.
