Abstract
Purpose
Disasters and armed conflict often co-occur, but does that imply that disasters trigger or fuel conflict? In the small but growing body of literature attempting to answer this question, divergent findings indicate the complex and contextual nature of a potential answer to this question. The purpose of this study is to contribute a robust cross-country analysis of the co-occurrence of disaster and conflict, with a particular focus on the potential role played by disaster.
Design/methodology/approach
Grounded in a theoretical model of disaster–conflict co-occurrence, this study merges data from 163 countries between 1990 and 2017 on armed conflict, disasters and relevant control variables (low human development, weak democratic institutions, natural resource dependence and large population size/density).
Findings
The main results of this study show that, despite a sharp increase in the co-occurrence of disasters and armed conflict over time, disasters do not appear to have a direct statistically significant relation with the occurrence of armed conflict. This result contributes to the understanding of disasters and conflicts as indirectly related via co-creation mechanisms and other factors.
Originality/value
This study is a novel contribution, as it provides a fresh analysis with updated data and includes different control variables that allow for a significant contribution to the field.

Design/methodology/approach
The authors proposed a novel risk assessment approach based on the multi-sensor fusion algorithm in the real traffic environment. Firstly, they proposed a novel detection-level fusion approach for multi-object perception in dense traffic environment based on evidence theory. This approach integrated four states of track life into a generic fusion framework to improve the performance of multi-object perception. The information of object type, position and velocity was accurately obtained. Then, they conducted several experiments in real dense traffic environment on highways and urban roads, which enabled them to propose a novel road traffic risk modeling approach based on the dynamic analysis of vehicles in a variety of driving scenarios. By analyzing the generation process of traffic risks between vehicles and the road environment, the equivalent forces of vehicle–vehicle and vehicle–road were presented and theoretically calculated. The prediction steering angle and trajectory were considered in the determination of traffic risk influence area.
Findings
The results of multi-object perception in the experiments showed that the proposed fusion approach achieved low false and missing tracking, and the road traffic risk was described as a field of equivalent force. The results extend the understanding of the traffic risk, which supported that the traffic risk from the front and back of the vehicle can be perceived in advance.
Originality/value
This approach integrated four states of track life into a generic fusion framework to improve the performance of multi-object perception. The information of object type, position and velocity was used to reduce erroneous data association between tracks and detections. Then, the authors conducted several experiments in real dense traffic environment on highways and urban roads, which enabled them to propose a novel road traffic risk modeling approach based on the dynamic analysis of vehicles in a variety of driving scenarios. By analyzing the generation process of traffic risks between vehicles and the road environment, the equivalent forces of vehicle–vehicle and vehicle–road were presented and theoretically calculated.

Abstract
Purpose
This paper aims to consider the realities and problematics of applying a grounded theory (GT) approach to research, as a novice, within a mixed methods study during post graduate research. Its intention is to provide the novice user with a framework of considerations and greater awareness of the issues that GT can expose during research activity.
Design/methodology/approach
Using empirical evidence and a comparative approach, the paper compares the efficacy of both the classic Glaserian and Straussian models. It observes the effects of a positivist academic environment upon the choice of approach and its application. This study was specific to design education; however, its reliance upon a social science epistemology results in findings beneficial to research novices across broader disciplines.
Findings
GT presents the novice researcher with several potential pitfalls. Most problematic were the immutable, positivist institutional requirements, researcher a priori knowledge, the reliance upon literature for the research proposal and structure of the proposal itself. These include suspension of the notion that the purist use of either model can be applied in the current academic environment, the need for a close relationship with the data and toleration of a non-linear process with unexpected results.
Originality/value
The practicalities of GT research are often reflected upon by the academy, but use by novice researchers is little considered. The findings from this study provide a novel set of guidelines for use by those embarking on GT research and particularly where the requirements of formal education may cause a conflict.

Abstract
This qualitative exploratory study focuses on the leadership experiences of college men who held leadership roles in campus organizations. The researchers examined the students’ experiences of leading their organizations and group members and the students’ perceptions of gender roles influencing their leadership practice. Four male participants at a medium-sized, religiously-affiliated university engaged in in-depth interviews and a focus group with the researchers, who used a blend of qualitative approaches to conduct the study and analyze the data. Key themes emerged around a balance between task and relationship-building; the distinction between power and influence; a desire to do better; understanding leadership as generative; and resisting the masculine/feminine leadership dichotomies. Implications are presented for professional practice and research.
