E-commerce has become one of the major consumption patterns currently. Understanding consumer e-commerce shopping behavior helps to improve the competitiveness of enterprises. The purpose of this study is to examine service justice as the antecedent factor of dysfunctional customer behavior (DCB) and how it interacts with negative emotion and service dissatisfaction, which in turn, affect DCB. ...

In an effort to foster research integrity, the National Institutes of Health and the National Science Foundation mandate education of all trainees in the responsible conduct of research (RCR). Nevertheless, recent studies suggest that rates of questionable research practices and scientific misconduct are both high and considerably underreported. In part, this may be due to the fact that some et...

Abstract The issue of whistleblowers is one great interest and controversy because EU Directive (EU) 2019/1937 the European Parliament Council 23 October 2019 on protection persons who report breaches Union law. While English meaning “whistleblowing” inherently positive not associated with anything negative, Polish translation word, “ sygnalista ”, often does evoke associations. Blowing whistle...

The effectiveness of steady and pulsed blowing as a method of controlling delta wing vortices during ramp pitching has been investigated in flow visualization experiments conducted in a water tunnel. The recessed angled spanwise blowing technique was utilized for vortex manipulation. This technique was implemented on a beveled 60° delta wing using a pair of blowing ports located beneath the vor...

This paper proposes a simple and automated referee whistle sound detection (RWSD) for sports highlights extraction and video summarization. The proposed method is based on preprocessor, linear phase bandpass finite impulse response (FIR) filter shorttime energy estimator and decision logic. At the processing stage the discrete audio sequence is divided into non-overlapping blocks and then ampli...

Resident killer whales off British Columbia form four acoustically distinct clans, each with a unique dialect of discrete pulsed calls. Three clans belong to the northern and one to the southern community. Resident killer whales also produce tonal whistles, which play an important role in close-range communication within the northern community. However, there has been no comparative analysis of...

Delphinids produce tonal whistles shaped by vocal learning for acoustic communication. Unlike terrestrial mammals, delphinid sound production is driven by pressurized air within a complex nasal system. It is unclear how fundamental whistle contours can be maintained across a large range of hydrostatic pressures and air sac volumes. Two opposing hypotheses propose that tonal sounds arise either ...

Studies on captive bottlenose dolphins, Tursiops truncatus, have shown that each individual produces a stereotyped, individually specific signature whistle; however, no study has demonstrated clear context-dependent usage of these whistles. Thus, the hypothesis that signature whistles are used to maintain group cohesion remains untested. To investigate whether signature whistles are used only i...
