Abstract
Purpose
Vertical lift (VL) assets are vital and expensive resources in humanitarian missions. What and where supplies are needed evolves in short time following a disaster. The purpose of this paper is to offer analysis to understand the range of capabilities of these assets.
Design/methodology/approach
The authors use scenario analysis to investigate the tradeoff between two key capabilities of VL, agility and speed. The authors do this by generating loads and distances randomly, based on historical data. In post hoc analysis, based on different factors, the authors investigate the impact of configuration of Expeditionary Strike Force (ESG) on providing disaster relief.
Findings
The authors find the most effective deployment of VL in a HADR mission is in supplying essentials to victims in a focused region. Delivering sustainment requirements leads to substantial shortfall for survival needs. If the configuration of the ESGs were changed for HADR, it would better-meet the demand.
Research limitations/implications
Cargo capacity is modeled assuming every aircraft type was equal, in terms of mean and variance of cargo-capacity utilization. Detailed information on cargo-bay configurations was beyond the scope of our model and data. However, this means the benefit of standardizing cargo load-outs and the variability associated with randomized load-outs may be understated in the results.
Practical implications
The analysis presents decision-makers with projections of VL asset performance in the early stages of disaster relief, to assist in planning and contingency planning.
Originality/value
This research deals exclusively with the most critical but expensive capabilities for HADR: VL. The in-depth analysis illustrates the limitations and benefits of this capability.

Abstract
In this paper, the authors elaborate the notion of a hybrid factory: factories in which some production capacity is dedicated to process‐oriented manufacturing, and some is dedicated to product‐oriented manufacturing. We present the results of a field study of one such factory and, using it as an example, develop a list of eight issues that may arise as a part of implementing and managing a hybrid factory. Where possible, we tie these issues into existing research streams. We show how our field site addressed these issues and, based on their experience, suggest new areas for investigation by researchers. An examination of the way our field site implemented and managed a hybrid factory also provides insight for managers facing similar situations.

Abstract
Performance Based Logistics (PBL) is an acquisition reform that is intended to improve weapon systems logistics by reducing cost, improving reliability, and reducing footprint. PBL is an extension of a broad process of rationalizing and, in many cases, outsourcing government services. As with other examples of governmental service outsourcing, measurement issues arise in the gap between governmental objectives and service measurement, and in the contrast between clear profit-centered vendor metrics, and more complex mission-oriented governmental metrics. Beyond this, however, PBL presents new challenges to the relationship between governmental agencies and their service vendors. In many cases, weapons systems logistical support involves levels of operational risk that are more difficult to measure and more difficult to value than other government services. We discuss the implications of operational risk and other measurement issues on PBL implementation.

Abstract
Like any established and mature body of scholarship, social movements research has changed, evolved, and grown over its decades. Now a robust and vibrant field in its own right, it has seen interpretive paradigms and theoretical frameworks come and go, and in some cases come again. A variety of frameworks and approaches have been used, emphasizing collective behavior, mobilizing structures, resource mobilization, cultural politics, social psychology, identities, cognition, framing, discourses, narratives, and emotions.

Abstract
Purpose
To implement and assess an intervention designed to promote gender equity and organizational change within STEM departments in two Colleges at a single Research High university. Department climate impacts the retention and success of women faculty.
Methodology/approach
A survey was administered both before and after the department intervention in order to capture departmental change on variables that measure a positive climate for female faculty.
Findings
Across all of the science and engineering departments, levels of Collective Efficacy toward Gender Equity significantly increased while levels of Conflict significantly decreased after the department facilitation. In the science departments, the level of Vicarious Experience of Gender Equity among faculty significantly increased while in the engineering departments levels of faculty Dependence significantly decreased. There was a statistically significant decrease in Optimism about Gender Equity among the science faculty.
Practical implications
Organizational change within universities has been documented as slow and labor intensive. Departmental climate, particularly interactions with colleagues, remains an area wherein women continue to feel excluded. The departmental intervention resulted in measurable improvements in key aspects of climate critical to women’s success (e.g., reductions in conflict and dependence; increases in collective efficacy) as well as more realistic view of the effort needed to attain gender equity (decrease in Optimism).

Abstract
In one of his most cited works, March (1991) observed that “The basic problem confronting an organization is to engage in sufficient exploitation to ensure its current viability and, at the same time, devote enough energy to exploration to exploration to ensure its future viability” (p. 105). The need to simultaneously pursue exploration and exploitation is a cornerstone of organizational ambidexterity, with the embedded assumption that exploratory ventures require organic management systems and exploitative activities benefit from more mechanistic management systems. The authors argue that this assumption about system alignment is neither well-supported by empirical evidence nor well-grounded in March’s original ideas about exploration and exploitation. The authors review the existing empirical evidence on the management systems that support exploration and exploitation and reveal some of the empirical and conceptual challenges. The authors then share a quasi-experimental study of 49 project teams over an 18-month period where they investigated how components of the management system – formalization, specialization, hierarchy, and leadership – differentially affect project success for explore and exploit projects. The authors find that exploitation projects can succeed under either mechanistic or organic systems, but that exploratory project performance suffers under a mechanistic system. In addition, the authors also find that leadership is the most important determinant of project success or failure. The authors discuss the implications of these results for future studies of organizational ambidexterity and draw attention to some of the underdeveloped ideas in March’s original article that might further advance the field.
