This study surveyed 309 business students (180 men and 129 women) enrolled in introductory accounting and business law classes on various aspects of honesty in academics. The study was motivated by the need to examine the underlying issues associated with students’ perceptions of cheating and whistle-blowing. An increased understanding of these perceptions would be insightful to professors as well as administrators. The study examines students’ reasons on whether they should whistle-blow and whether their reasons associate with their intentions to whistle-blow if they observe cheating. When examining a student's intent to whistle-blow, we considered the student's prior cheating behavior, gender, social desirability response bias, intentions to cheat in the future, reasons not to whistle-blow, and prior whistle-blowing. Our data extends prior research by considering the reasons students choose not to whistle-blow. Our research indicates that the number of reasons not to whistle-blow and having observed other students cheating reduced the likelihood of a student whistle-blowing, after controlling for social desirability response bias. The research indicates that to prevent unethical behavior in the future, institutions need to enforce consequences for those who cheat because unethical behavior at the academic level associates with unethical behavior in the corporate setting.

The purpose of this paper is to investigate the use of 802.11e MAC to resolve the transmission control protocol (TCP) unfairness.

The paper shows how a TCP sender may adapt its transmission rate using the number of hops and the standard deviation of recently measured round‐trip times to address the TCP unfairness.

Simulation results show that the proposed techniques provide even throughput by providing TCP fairness as the number of hops increases over a wireless mesh network (WMN).

Future work will examine the performance of TCP over routing protocols, which use different routing metrics. Other future work is scalability over WMNs. Since scalability is a problem with communication in multi‐hop, carrier sense multiple access (CSMA) will be compared with time division multiple access (TDMA) and a hybrid of TDMA and code division multiple access (CDMA) will be designed that works with TCP and other traffic. Finally, to further improve network performance and also increase network capacity of TCP for WMNs, the usage of multiple channels instead of only a single fixed channel will be exploited.

By allowing the tuning of the 802.11e MAC parameters that have previously been constant in 802.11 MAC, the paper proposes the usage of 802.11e MAC on a per class basis by collecting the TCP ACK into a single class and a novel congestion control method for TCP over a WMN. The key feature of the proposed TCP algorithm is the detection of congestion by measuring the fluctuation of RTT of the TCP ACK samples via the standard deviation, plus the combined the 802.11e AIFS and CW_min allowing the TCP ACK to be prioritised which allows the TCP ACKs will match the volume of the TCP data packets. While 802.11e MAC provides flexibility and flow/congestion control mechanism, the challenge is to take advantage of these features in 802.11e MAC.

With 802.11 MAC not having flexibility and flow/congestion control mechanisms implemented with TCP, these contribute to TCP unfairness with competing flows.

This study surveyed 195 business students (74 women and 121 men) from three institutions on various aspects of honesty in academics. The study is driven by a concern for the audit implications of the increasing evidence of the link between unethical behavior in college and the workplace and students’ increasing insensitivity to ethical issues. The results of the study evaluate students’ opinions of cheating and the percentage of students who have or would whistle-blow if they observe cheating. The study also examined whether characteristics such as prior cheating behavior, gender, social desirability response bias (SDRB), the belief about doing more about cheating, and prior whistle-blowing will affect a student's intent to whistle-blow. Our data extends prior research on cheating and SDRB by testing their association with students’ self-reported tendency to whistle-blow. Our research indicates that students who have whistle-blown have a higher reported intention to whistle-blow after accounting for the effect of SDRB. Our data indicate that students’ intentions are an important factor that should be considered by instructors as well as researchers.

Summarizes the basic principles of Bioenergetics along with its origin in Riechian psychology. Clarifies that Bioenergetics is used at Cranfield not as psychotherapy, but as an aid to personal development for a specific population of high‐functioning individuals, i.e. managers. Places the Bioenergetic body‐mind notion into a philosophical context of human goodness and potential; thus expanding the focus to body‐mind‐spirit. Examines five body‐mind types through the following aspects: how they operate at work; how they were formed; key attitudes; unique gifts; body shape; development path; how they are best managed. Case histories illustrating the different types in various modes of consultant intervention, i.e. individual development, team building and culture change.

The wind is kicking up at Spadero Airport in the resort town of East Moriches, Long Island. A single‐engine propellered Cessna 182 wobbles in the clear blue sky, as it ascends above the tree line at the end of the runway. Just being on board under conditions like this can be intimidating. To some people, anyway. Others crave more, hurling themselves out of the aircraft to get blown about in the wind before releasing a parachute and sailing to earth.

Piston ring dynamic problem plays an important role in the lubricant characteristics of a reciprocating engine, which lead to engine wear and the increased consumption of lubricating oil. A cavitation analysis of the piston ring lubrication with two-dimensional Reynolds equation has rarely been reported owing to the complex working condition. The purpose of this study is to establish a precise model that can provide guidance for the design of the piston ring.

In this paper, a cavitation model and its effect on the piston ring lubrication was studied in a simulation program based on the mass-conserving theory which is solved by means of the Newton–Raphson method. In this study, some models such as mixed lubrication, asperity contact, blow-by/blow-back flow and cavitation have been coupled with the lubrication model.

The established model has been compared with the traditional model that deals with cavitation by using the Reynolds boundary condition algorithm. The cavitation zone, pressure distribution and density distribution between the piston ring and the cylinder have also been predicted. Studies of the changing trend for the pressure distribution and the cavitation zone at few typical crank angles have been listed to illustrate the cavitation changing rule. The analysis of the results indicates that the developed simulation model can adequately illustrate the lubrication problem of the piston ring system. All the analyses will provide guidance for the oil film rupture and the reformation process.

A two-dimensional cavitation model based on the mass-conserving theory has been built. The cavitation-forming and -developing process for the piston ring–liner lubrication has been studied. Non-cavitation occurs in the vicinity of top dead center and bottom dead center. The non-cavitation period will be longer in the vicinity of 360° of crank angle. The density distribution in the cavitation zone can be obtained.

Covert feathers on avian wings can show dynamic pop-up behaviour in rapid succession as a reaction to turbulent gusts. The purpose of this paper is to understand the possible flow control mechanism induced during such dynamic motion cycles. A model aerofoil is designed with suction side spanwise control of rows of bio-inspired flaplets.

A NACA 0012 aerofoil is equipped with a spanwise row of eight flaplets at 80% chord, connected to pneumatic actuators and can be deployed to max 15° in a prescribed open–hold–close manner. The model is placed in a water tunnel and flow measurements are done in the wake of the flaps during a cycle using particle image velocimetry.

During opening, boundary layer flow is sucked into the void space between the wing surface and the flaplet, which induces backflow underneath the flaplet and traps the fluid inside. This fluid is expelled downstream during closure, which generates a forward directed jet as seen by the formation of a vortex-ring like structure with higher axial momentum. The entrainment of the jet leads to the re-energising of the boundary layer flow further upstream.

This paper presents a furtherment of understanding of the action of pop-up feathers for separation control. The actuation of the bio-inspired flaplets shows a flow vectorising effect which can be used for active separation and gust control. In the case of incipient separation, flaplet action can act to re-attach the flow because of the jet entrainment effect.
