The objective of the present study was to examine the incidences of violence during nurses' careers and their impacts on their work life in the Islamic Republic of Pakistan. The current article highlights workplace violence toward nurses as a serious issue in Pakistan, which is almost an unexplored area as data are scarce. Individual interviews were conducted, applying a qualitative approach for getting the in-depth knowledge about the subject. Grounded theory method was used for data analysis and NVIVO-10 was used for information processing. Majority of the nurses experienced violence in the previous 6 months of their career. Nurses also confirmed that verbal abuse was witnessed and although experienced frequently, they did not report it, as they believed that reporting was useless and no action would be taken. Most nurses reported that due to violence, they experience stress, low work performance, low job satisfaction, high absenteeism, and high turnover intentions. The results illustrated a clear trend of an increasing number of violence incidents toward nurses. The findings of the present study possibly will assist hospital administration to manage and reduce violence at workplace.

PurposeDrawing on affective events theory, the authors investigated whether exposure to abusive supervision triggers malevolent creativity among victims and the role of psychological contract violation (PCV) as a mediator in this relationship. The authors also examined the moderating effects of the Light Triad personality traits comprising Kantianism, humanism and faith in humanity.Design/methodology/approachThe sample comprised 297 junior doctors working at various clinical departments of public sector hospitals in three major cities of Pakistan. Data were collected using a self-administered questionnaire and the hypothesized model was tested using the covariance-based structural equation modeling in Mplus.FindingsResults demonstrated that abusive supervision influences malevolent creativity directly and indirectly mediated through PCV. Further, results showed that individuals high on the Light Triad traits are less likely to engage in malevolently creative acts in response to abusive supervision and feelings of violation than those low on the Light Triad.Originality/valueThe authors contribute to the literature by demonstrating that exposure to abusive supervision influences the generation of malevolently creative ideas among subordinates. Further, the authors showed that subordinates high on the Light Triad handle abusive supervisory behaviors and negative emotional reactions more productively and are less likely to retaliate against perceived mistreatment compared to their counterparts.

Public-key cryptosystems such as elliptic curve cryptography (ECC) and Rivest-Shamir-Adleman (RSA) are widely used for data security in computing systems. ECC provides a high level of security with a much smaller key than RSA, which makes ECC a preferred choice in many applications. This study proposes a multi-key ECC based on the residue number system. The proposed architecture employees deep pipelining to allow the concurrent encryption of 21 keys. The proposed architectures are implemented on two different field programmable gate array (FPGA) platforms and results are compared with existing ECC architectures. The proposed implementation on Virtex-7 FPGA achieves a throughput of 1816 kbps at a clock frequency of 73 MHz.
