    In the recent years, we have witnessed a tremendous growth and development in the field of wireless communication technology and sensors. Resulting into opening new dimensions in various research fields. The integration of Nano scale devices with low power consumption circuits brought a new evolution in wireless networks. This blend of technologies led to the formation of a new field in WSN (Wireless Sensor Networks) known as WBAN (Wireless Body Area Network). WBAN is based on small sensors designed to operate and function mainly on the human body. As we are dealing with human lives, security and privacy are major concerns as patients’ data is at the stakes. Authentication is an important factor in securing information from unauthorized usage. Now-a-days a lot of research has been done in order to improve the overall authentication mechanisms in WBAN. In this poster, we are surveying the security challenges in WBAN with a focus on the authentication phase. A list of several methods along with their schemes has been studied and recapitulated. ECG is one the most popular schemes used in WBAN, benefiting from its uniqueness. However, it comes with challenges as creating an extract trait could get complicated. ECG could be aided by the help of combining fingerprint which will result in a non-destructive method of biometric authentication compared with single ECG trait

    Assuming Data Integrity and Empirical Evidence to The Contrary

    Background: Not all respondents to surveys apply their minds or understand the posed questions, and as such provide answers which lack coherence, and this threatens the integrity of the research. Casual inspection and limited research of the 10-item Big Five Inventory (BFI-10), included in the dataset of the World Values Survey (WVS), suggested that random responses may be common. Objective: To specify the percentage of cases in the BRI-10 which include incoherent or contradictory responses and to test the extent to which the removal of these cases will improve the quality of the dataset. Method: The WVS data on the BFI-10, measuring the Big Five Personality (B5P), in South Africa (N=3 531), was used. Incoherent or contradictory responses were removed. Then the cases from the cleaned-up dataset were analysed for their theoretical validity. Results: Only 1 612 (45.7%) cases were identified as not including incoherent or contradictory responses. The cleaned-up data did not mirror the B5P- structure, as was envisaged. The test for common method bias was negative. Conclusion: In most cases the responses were incoherent. Cleaning up the data did not improve the psychometric properties of the BFI-10. This raises concerns about the quality of the WVS data, the BFI-10, and the universality of B5P-theory. Given these results, it would be unwise to use the BFI-10 in South Africa. Researchers are alerted to do a proper assessment of the psychometric properties of instruments before they use it, particularly in a cross-cultural setting

    Leading Towards Voice and Innovation: The Role of Psychological Contract

    Background: Empirical evidence generally suggests that psychological contract breach (PCB) leads to negative outcomes. However, some literature argues that, occasionally, PCB leads to positive outcomes. Aim: To empirically determine when these positive outcomes occur, focusing on the role of psychological contract (PC) and leadership style (LS), and outcomes such as employ voice (EV) and innovative work behaviour (IWB). Method: A cross-sectional survey design was adopted, using reputable questionnaires on PC, PCB, EV, IWB, and leadership styles. Correlation analyses were used to test direct links within the model, while regression analyses were used to test for the moderation effects. Results: Data with acceptable psychometric properties were collected from 11 organisations (N=620). The results revealed that PCB does not lead to substantial changes in IWB. PCB correlated positively with prohibitive EV, but did not influence promotive EV, which was a significant driver of IWB. Leadership styles were weak predictors of EV and IWB, and LS only partially moderated the PCB-EV relationship. Conclusion: PCB did not lead to positive outcomes. Neither did LS influencing the relationships between PCB and EV or IWB. Further, LS only partially influenced the relationships between variables, and not in a manner which positively influence IWB
