This study focuses on the implementation of Learning Management System (LMS) in the higher education sector in Iraq. Its aim is to develop a policy adoption framework for LMS implementation by scientifically investigating LMS adoption using a model that combines the principles of the Technology Acceptance Model (TAM) and Technology-Organisation-Environment (TOE) framework. The research methodology comprises of seven stages that adopts the interpretive paradigm and a mixed-methods research design. A case study design is used to investigate LMS integration in the University of Al-Qadisiyah. A TAM-TOE questionnaire is developed for the academic staff of the University of Al-Qadisiyah, in which the perceived usefulness and perceived ease of use of LMS are analysed in the case organisation. The technological, organisational, and environmental aspects of LMS implementation are also examined. The survey received valid responses from 283 academic staff. In-depth semi-structured interviews of 8 academics, administrative staff and IT personnel contributed to the qualitative data. The survey respondents are selected using stratified sampling whilst purposive sampling is used to select the interview participants. The questionnaire data was analysed using correlation analysis, whilst thematic analysis is used for the interview data. The study identifies the barriers to LMS implementation as: Lack of or limited teachers’ training, lack of commitment to constructivist pedagogy, lack of experience to use the new technology, lack of technical support, and lack of appropriate educational software. These results feed into the policy framework design. The contribution to research knowledge includes the creation of a new adoption model derived from TAM and TOE to examine the LMS implementation barriers in a war recovering economy like Iraq. This approach the integration of academic users’ acceptance with macro-level factors like government support. The results lease to the development of the LMS policy framework to guide policy makers to prioritise their limited LMS investments. The novelty of the work is the bringing together the considerations of the individual users and the socio-economic context.

In recent years a strong interest has been expressed to produce lighter structures.One possible solution to reduce the weight is to utilize high strength steels and use welding as the joining method. Many components experience fatigue loadingduring all or part of their life time and welded connections are often the prime location of fatigue failure. This becomes more critical in welded high strength steels as fatigue strength of welds does not increase by increasing the steel strength. A possible solution to overcome this issue is to use fatigue improvement methods.The main objectives of this project are, therefore, to increase understanding of the factors that control fatigue life and to investigate how the fatigue strength improvement methods; high frequency mechanical impact (HFMI) treatment and use of Low Transformation Temperature (LTT) consumables will affect fatigue properties of welds in high strength steels. In this regard, Gas Metal Arc Welding(GMAW) was used to produce butt and fillet welds using LTT or conventional fillers in steels with yield strengths ranging from 650-1021 MPa and T-joint weldsin a steel with 1300 MPa yield strength. The effect of HFMI on fatigue strength of the welds in 1300 MPa yield strength steels was also investigated. Butt and fillet welds in 650-1021 MPa steels were fatigue tested under constant amplitude tensile loading with a stress ratio of 0.1 while T-joints were fatigue tested under constant amplitude fully reversed bending load with a stress ratio of -1. The nominal stress approach was used for fatigue strength evaluation of butt and fillet welds whereas the effective notch stress approach was used in case of T-joints. Relative effectsof the main parameters such as residual stress and weld toe geometry influencing fatigue strength of welds were evaluated. Residual stresses were measured using X-ray diffraction for as-welded and HFMI treated welds. Neutron diffraction was additionally used to investigate the near surface residual stress distribution in 1300 MPa LTT welds.Results showed that use of LTT consumables increased fatigue strength of welds in steels with yield strengths ranging from 650-1021 MPa. For butt welds, the vii characteristic fatigue strength (FAT) of LTT welds at 2 million cycles was up to46% higher when compared to corresponding welds made with conventional fillermaterials. In fillet welds, a maximum improvement of 132% was achieved when using LTT wires. The increase in fatigue strength was attributed to the lower tensile residual stresses or even compressive stresses produced close to the weldtoe in LTT welds. Weld metals with martensite transformation start temperatures around 200 °C produced the highest fatigue strength. In 1300 MPa yield strength steel, similar FAT of 287 MPa was observed for LTT welds and 306 MPa for conventional welds, both much higher than the IIW FATvalue of 225 MPa. The relative transformation temperatures of the base and weldmetals, specimen geometry and loading type are possible reasons why the fatigue strength was not improved by use of LTT wires. Neutron diffraction showed that the LTT consumable was capable of inducing near surface compressive residual stresses in all directions at the weld toe. It was additionally found that there arevery steep stress gradients both transverse to the weld toe line and in the depth direction, at the weld toe. Due to difficulties to accurately measure residual stresses locally at the weld toe most often in the literature and recommendations residual stresses a few millimetre away from the weld toe are related to fatigue properties. However, this research shows that caution must be used when relating these to fatigue strength, in particular for LTT welds, as stress in the base materiala few millimetre from the weld toe can be very different from the stress locally at the weld toe.HFMI increased the mean fatigue strength of conventional welds in 1300 MPa steels about 26% and of LTT welds by 13%. It increased the weld toe radius slightly but produced a more uniform geometry along the treated weld toes. Large compressive residual stresses, especially in the longitudinal direction, were introduced adjacent to the weld toe for both LTT and conventional treated welds. It was concluded that the increase in fatigue strength by HFMI treatment is due to the combined effect of weld toe geometry modification, increase in surface hardness and introduction of compressive residual stresses in the treated region.It was concluded that the residual stress has a relatively larger influence than the weld toe geometry on fatigue strength of welds. This is based on the observation that a moderate decrease in residual stress of about 15% at the 300 MPa stress level had the same effect on fatigue strength as increasing the weld toe radius by approximately 85% from 1.4 mm to 2.6 mm, in fillet welds. Also, a higher fatigue strength was observed for HFMI treated conventional welds compared to as welded samples having similar weld toe radii but with different residual stresses.

Technological innovations are one of the most impactful occurrences in our lives nowadays. Almost every product or service is being transformed into a more ubiquitous one due to the expectation of offering a better experience or becoming economically more viable. One of the most recent common instances is cities that transforms into smart ones. Many functions of smart cities are upgraded digitally in order to improve their service. This study is inspired by this aspect to focus on the shopping side of the cities. The most common type of retailing is shopping malls and there is evidence to lead this paper to point out how smartness could be impactful for the shopping malls. Furthermore, there is strong evidence that shows that online shopping is getting popular and shopping malls are in their maturity stage in terms of the Life-Cycle concept. Shopping malls’ customer turnover is increasing every year and smartness could be the spark to overcome this obstacle. Therefore, this paper’s research focus has formed into the possible determinant factors that could be significant in the case of adoption of smartness into shopping malls and possible facts that could create value for the shopping malls in the purpose of eliminating the current obstacles that shopping malls are facing.
