    Assuming Data Integrity and Empirical Evidence to The Contrary

    Get PDF
    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

    Get PDF
    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

    Bifurcation analysis of the Topp model

    In this paper, we study the 3-dimensional Topp model for the dynamicsof diabetes. We show that for suitable parameter values an equilibrium of this modelbifurcates through a Hopf-saddle-node bifurcation. Numerical analysis suggests thatnear this point Shilnikov homoclinic orbits exist. In addition, chaotic attractors arisethrough period doubling cascades of limit cycles.Keywords Dynamics of diabetes · Topp model · Reduced planar quartic Toppsystem · Singular point · Limit cycle · Hopf-saddle-node bifurcation · Perioddoubling bifurcation · Shilnikov homoclinic orbit · Chao

    The String Landscape and the Swampland. The Weak Gravity Conjecture and Scalar Fields

    Get PDF
    Our Universe is governed by few fundamental forces: the electromagnetic and the weak interactions, the strong interaction, the Higgs-mediated interaction and the gravitational interaction. While the first four forces are described by the Standard Model (and extensions of it), gravity is described by General Relativity, which is a classical (in the sense of non-quantum) theory. Convinced that gravity is a fundamental force and so has to be quantic (for consistency with all the other fundamental interactions), the way to quantize it has to be found. Animated by the belief that String Theory (which is the only consistent model we can refer to and make calculation with for now) is predictive, it is quite natural to ask ourselves how Nature has selected our Universe among the ``jungle" of possible universes allowed by String Theory itself. Nowadays, a popular approach to face such debate is represented by the so called ``Swampland program”. Among all consistent-looking 4-dimensional effective Quantum Field Theories, only few are completable in String Theory or (more generally) in Quantum Gravity in the ultraviolet. Such few theories are said to belong to the Landscape. The abstract concept of Swampland acquires consistency only if it possible to distill it out from that of Landscape. The present thesis work places itself right here. Besides the rich variety of Swampland conjectures that one can consider, we have concentrated our attention on the ``Weak Gravity Conjecture” (WGC). In words, it is the statement according to which gravity acts as the weakest force in any circumstance. After having presented its best known version (in the presence of a U(1) gauge field) and being conscious of the fact that (likely) two scalar fields (the Higgs field and the inflaton) play a crucial role in our Universe and that many scalar fields appear in theories going beyond the Standard Model and in supergravity theories, we have deepened the study of the scalar WGC (SWGC). In particular, we have presented the SWGCs recently (2017) proposed by E. Palti and we have investigated a strong SWGC proposal (SSWGC) that E. Gonzalo and L. Ibàñez have made in April (2019). We have managed to show that, despite of being a potentially powerful tool constraining the Standard Model and many inflationary models, Gonzalo and Ibàñez's conjecture exhibits various criticisms and is in tension with the physical principle that animates the WGC itself. In order to try to get to a general statement (overcoming Gonzalo and Ibàñez's claim) we have elaborated and studied some models. By imposing that gravity is the weakest force, we have got some constraints involving the relevant parameters of such theories, that are coherent with Palti's SWGCs. This gives support to its approach in dealing with the scalar versions of the WGC and has suggested to us a way to really proceed forward (beyond known results).ope
