Abstract
DoD accidents are classified according to the severity of injury, occupational illness, and vehicle and/or property damage costs (Department of Defense, 2000). All branches of the military have similar accident classification schemes, with Class A being the most severe. Table 1 shows the accident classes for the Army. The Air Force and Navy definitions of Class A–C accidents are very similar to the Army's definition. However, they do not have a Class D. As the total costs of some Army UAVs are below the Class A criteria ($325,000 per Shadow aircraft; Schaefer, 2003), reviewers have begun to add Class D data into their analyses (Manning, Rash, LeDuc, Noback, & McKeon, 2004; Williams, 2004).

Abstract
Purpose
The purpose of this paper is to give insight on the important preparation task needed to be considered by prospective PhD candidates prior to the start of their study. As pursuing and obtaining a higher degree qualification is becoming more eminent for those who want to advance their academic career, crucial preparation is needed before embarking on the doctoral quest.
Design/methodology/approach
A small-scale study of the PhD experience was carried out in a public university in Malaysia using semi-structured in-depth interviews with eight successful doctoral students representing three different faculties to assess respondents’ experiences concerning the preparation aspect, challenges faced and strategies used to overcome the problem.
Findings
From the interview data, three overarching themes emerged: motives, task and financial and health as important dominators that could influence a successful venture of a PhD journey.
Research limitations/implications
As the present research respondents were few, further research with bigger number of respondents may shed better light in identifying other important aspect in preparation for PhD. The authors are unable, in the space of this paper, to fully explore the implications of the data, and the work of others that it builds on, for the future of professional doctorates or other types of PhD awards. As professional doctorates are fully concentrated on their professional endeavour, i.e. nursing and education, the preparation needed may include different groundwork. In addition, this study was carried out in Malaysia, where the system may not necessarily share the same characteristics to other doctoral systems in other countries. Cultural differences, the impact of age, gender and race, were other variables that could be weighed by future research in the same area.
Practical implications
The university’s graduate office should line-up courses to inform future doctoral candidates on the aspect of preparation at personal level that the students need to carry out.
Social implications
The study provides new views where potential doctoral students should be helped and guided to become more consciously aware of their decision in pursuing a higher degree. This paper provides suggestions on the guidelines of the initial preparation needed before embarking on a PhD journey and managing their own learning.
Originality/value
The paper establishes the important aspect of the preparation phase needed to be considered by future doctoral students before pursuing their doctoral quest.

Abstract
Purpose
This paper aims to study the Gramian solutions and solitonic interactions of a (2 + 1)-dimensional Broer–Kaup–Kupershmidt (BKK) system, which models the nonlinear and dispersive long gravity waves traveling along two horizontal directions in the shallow water of uniform depth.
Design/methodology/approach
Pfaffian technique is used to construct the Gramian solutions of the (2 + 1)-dimensional BKK system. Asymptotic analysis is applied on the two-soliton solutions to study the interaction properties.
Findings
N-soliton solutions in the Gramian with a real function ζ(y) of the (2 + 1)-dimensional BKK system are constructed and proved, where N is a positive integer and y is the scaled space variable. Conditions of elastic and inelastic interactions between the two solitons are revealed asymptotically. For the three and four solitons, elastic, inelastic interactions and soliton resonances are discussed graphically. Effect of the wave numbers, initial phases and ζ(y) on the solitonic interactions is also studied.
Originality/value
Shallow water waves are studied for the applications in environmental engineering and hydraulic engineering. This paper studies the shallow water waves through the Gramian solutions of a (2 + 1)-dimensional BKK system and provides some phenomena that have not been studied.

Abstract
Machiavelli's dictums in The Prince (1977) instigated the modern discourse on power. Arguing that “there's such a difference between the way we really live and the way we ought to live that the man who neglects the real to study the ideal will learn to accomplish his ruin, not his salvation” (Machiavelli, 1977, p. 44), his approach is a realist one. In this text, Machiavelli (1977, p. 3) endeavors to “discuss the rule of princes” and to “lay down principles for them.” Taking his lead, Foucault (1978, p. 97) argued that “if it is true that Machiavelli was among the few…who conceived the power of the Prince in terms of force relationships, perhaps we need to go one step further, do without the persona of the Prince, and decipher mechanisms on the basis of a strategy that is immanent in force relationships.” He believed that we should “investigate…how mechanisms of power have been able to function…how these mechanisms…have begun to become economically advantageous and politically useful…in a given context for specific reasons,” and, therefore, “we should…base our analysis of power on the study of the techniques and tactics of domination” (Foucault, 1980, pp. 100–102). Conceptualizing such techniques and tactics as the “art of governance”, Foucault (1991), examined power as strategies geared toward managing civic populations through shaping people's dispositions and behaviors.

Abstract
Purpose
The present research aims to manage the formulations of pigment-based inks containing aminopropyl/vinyl/silsesquioxane (APSV) as a pigment binding agent for inkjet printing of polyester as a commercial trial for the printing of polyester as a single-step process.
Design/methodology/approach
The proposed formulations incorporated APSV by using the mini-emulsion technique at a low relieving temperature under the thermal initiation or UV radiation of vinyl-terminated groups in APSV. In this study, the storage stability of inks with regard to physical properties was broadly examined. Moreover, the color performance, including colorimetric data, color fixation and fastness properties of printed fabrics was evaluated.
Findings
The results indicated that the inks containing APSV were formulated and were stable in terms of particle size, dispersion stability, surface tension and viscosity over a period of one month and for four freeze/thaw cycles. APSV successfully fixed the pigment-based inkjet inks on polyester fabric and could achieve a significantly higher color performance and degree of fixation than the formulated inks without APSV.
Research limitations/implications
It could also fulfill all the physical properties of ink prerequisites over storing and eliminating all challenges in improving the performance and utilization of inkjet printing.
Practical implications
APSV can also be used as a pigment binding agent to formulate inks for inkjet printing of polyester fabrics as the authors’ past examination for inkjet printing of polyester fabrics post-treated with APSV.
Social implications
This study eliminates the noteworthy challenges in formulating the pigment-based inks for textile applications by incorporation of a binder while keeping up the necessary viscosity profile for a specific print head.
Originality/value
This study addressed all the issues arising from the complex nature and very challenging requirements of inkjet inks.

Abstract
Purpose
The purpose of this paper is to examine the effect of knowledge management capabilities (KMCs) on supply chain management practices (SCMP) and organizational performance (OP) in firms, in addition to examining the effect of supply chain management on OP.
Design/methodology/approach
To demonstrate the effect of KMCs on SCMP, and OP, different techniques such as factor analysis, correlation analysis, and structural equation modeling were used to verify the validity of the proposed conceptual model and to test the suggested hypotheses, using data collected from 165 companies in the Saudi food industry (representing a response rate of 74.9 percent).
Findings
According to the study’s findings, SCMP are positively affected by KMCs. Moreover, OP is directly affected by KMCs and SCMP.
Research limitations/implications
Due to the specific nature of the sample, the findings of the current research are applicable only to the food industry.
Originality/value
The current research introduced a conceptual model, which has been tested and verified in the Saudi food industry. The findings recommend that both KMCs as well as SCMP will contribute to improving the OP. In addition, KMCs will improve the SCMP.

The purpose of this paper is to examine the temporal impact of individual and institutional investor sentiment on sin stock returns.
Abstract
Purpose
The purpose of this paper is to examine the temporal impact of individual and institutional investor sentiment on sin stock returns.
Design/methodology/approach
The authors estimate vector autoregressive models (VARs) to assess the dynamic relationships amongst pure sin returns and both types of investor sentiment. The justification for estimating VARs is that it allows one to study the potential influence that shocks (i.e. innovations) in individual and institutional investor sentiment might have on pure sin returns over time. Sin stock returns are separated into a market-based and pure sin component. Additionally, the authors split both measures of investor sentiment into rational- and irrational-based components.
Findings
This study finds that shocks to both individual and institutional rational-based sentiment positively influence pure sin returns for up to four months. However, irrational-based shocks have a positive, weaker and insignificant effect on pure sin returns. In addition, the results for the pure sin portfolio are compared to the S&P 500 and a comparables portfolio. The results show that sin stocks are less responsive than the S&P and the comparables portfolio to shocks in investor sentiment.
Originality/value
This study addresses some of the limitations found in the only prior study of sin stocks and investor sentiment (Perez Liston, 2016). Specially, this study investigates the link between sin stocks and sentiment in a dynamic context and also focuses the analysis on pure sin returns.

Abstract
Purpose
This study aims to explore consumers' perceptions of stealing thunder and to investigate significant factors for maximizing its effect.
Design/methodology/approach
This study used a mixed-methods approach. First, qualitative responses from 286 Korean participants were collected and analyzed (Study 1). Second, the experiment employed a randomized 2 (crisis communication timing: stealing thunder vs thunder) × 2 (transparent vs nontransparent communication) × 2 (follow-up actions: good vs poor) between-subjects experimental design with 426 Korean participants to investigate and confirm the results of Study 1.
Findings
Qualitative data showed that the participants' evaluation of corporations' stealing thunder strategy is complicated. Some do not perceive corporate use of stealing thunder at face value, but rather view it as yet another hopeless, selfish and irresponsible crisis communication strategy, distrusting it based on strong cynicism toward all corporations. An experiment confirmed that stealing thunder was significantly more effective in eliciting consumers' ethical judgment (EJ) and word-of-mouth (WOM) on corporations than the thunder strategy. Significant two-way interaction effects between crisis timing and follow-up actions showed that the stealing thunder strategy should be accompanied by follow-up actions to increase consumers' credibility and WOM intentions.
Originality/value
This study investigated how consumers evaluate stealing thunder by adopting both a qualitative and quantitative approach to explore how they make meaning out of this phenomenon.
