Globalisation and rapid environmental change have created many challenges for public and private organisations across Iraq as a developing country, particularly in the higher education sector. This includes, for example, decreases in government funding; increased demand for higher education; a need for economic transformation, and related competitiveness of organizations. Such challenges require exceptional leaders and strategic planning in order to take action to improve. In Iraq, the higher education sector is still one of the main foundations in progressing the knowledge economy. Studies into leadership style, strategic planning processes, and the importance of leadership and organisational culture to an organisation’s success have been used to assist both public and private Iraqi colleges in responding to the challenges they face. Although, some studies have examined the interaction between leadership and strategic planning, and leadership and organisational success, there has been no empirical study that has investigated how these three variables interact together. Thus, this study aimed, firstly, to identify the current leadership styles and strategic planning processes in the colleges and the challenges they faced, and to gain an understanding from the perspective of the senior leaders themselves as to how they might best respond to the current situation. Secondly, based on the participants’ experiences, knowledge and perceptions, the study aimed to identify implications for both practice and policy to help improve the colleges’ outcomes. The study involved a mixed-methods approach and was conducted in two stages. During the first stage, the researcher gathered quantitative data by administering a survey package to 129 leaders (deans, associate deans, and heads of departments) across both public and private colleges in the capital city of Baghdad. During the second stage, the researcher gathered qualitative data to more deeply explore the survey results by conducting individual interviews with a sub-sample of 21 leaders from both college types (ten public and 11 private). In the data analyses stages, both descriptive statistics and inferential statistics were applied to compiling tables and charts, and to test hypotheses, by employing the Statistical Package for Social Sciences (SPSS), Microsoft Excel, and NVivo. The results of study showed that both transformational and transactional leadership styles played a varied and vital role in the colleges’ strategic planning processes, and in turn their success. The fact that private colleges were ‘for profit’ and public colleges were ‘not for profit’, as well as their contrasting funding models, highlighted key differences between the two college types’ leadership and general modus operandi. While it was found that both transformative leadership and transactional leadership styles were necessary to address the challenges colleges faced in the Iraqi educational context, the impetus for change extended far beyond the need for professional development of leaders. The embracing of information communication technologies, and reliable Internet was seen as necessary in all aspects of the colleges’ work and provision for teaching and learning, and students’ success. This applied to both college types along with the need for closer adherence to government regulations and more focused government coordination of colleges’ administrative functions. Furthermore, implications for making successful improvements to practice also identified the need to manage the challenge of sociocultural influences on the appointments and promotions of leaders. It was concluded that a greater emphasis on teamwork and provision of incentives for staff, along with a ‘boost’ to pedagogy and practice, which could be provided through the adoption of information communication technologies and appropriate professional development strategies, would enhance the colleges’ ranks and the status of their qualifications. Also, theoretically, the study offers a value-add to leadership, strategic planning process, and organisational success literature in the form of a conceptual model that links these variables in the context of Iraqi higher education sector.
Periodontitis is a dysbiosis-driven inflammatory disease in which a pathogenic subgingival biofilm disrupts the host–microbe equilibrium and promotes progressive loss of tooth-supporting tissues. While periodontal destruction has traditionally been explained mainly through the host immune response, increasing experimental and clinical evidence suggests that epithelial–mesenchymal transition (EMT)-like changes in the gingival epithelium may contribute to barrier failure and tissue remodeling during disease progression. EMT is characterized by reduced epithelial adhesion and polarity, alongside a shift toward a mesenchymal-like phenotype with enhanced motility and impaired epithelial barrier function.

Concrete columns with hollow-core sections find widespread application owing to their excellent structural efficiency and efficient material utilization. However, corrosion poses a challenge in concrete buildings with steel reinforcement. This paper explores the possibility of using glass fiber-reinforced polymer (GFRP) reinforcement as a non-corrosive and economically viable substitute for steel reinforcement in short square hollow concrete columns. Twelve hollow short columns were meticulously prepared in the laboratory experiments and subjected to pure axial compressive loads until failure. All columns featured a hollow square section with exterior dimensions of (180 × 180) mm and 900 mm height. The columns were categorized into

Pharmaceuticals have been widely remaining contaminants in wastewater, and diclofenac is the most common pharmaceutical pollutant. Therefore, the removal of diclofenac from aqueous solutions using activated carbon produced by pyrocarbonic acid and microwaves was investigated in this research. Apricot seed powder and pyrophosphoric acid (45 wt%) were selected as raw material and activator respectively, and microwave irradiation technique was used to prepare the activated carbon. The raw material was impregnated in pyrophosphoric acid at 80◦C with an impregnation ratio of 1: 3 (apricot seeds to phosphoric acid), the impregnation time was 4 h, whereas the power of the microwave was 700 watts with a radiation time of 20 min. A series o

Background. Implant insertion in regions with poor bone quantity, such as the posterior maxilla, is potentially associated with an increased rate of implant failure. Calcium sulfate can be used as the coating material for commercially pure titanium (CpTi) and as the bone graft material around implants when bound to eggshell powder to enhance the bone quality and quantity of bone defect regions. This study performed a torque removal test to evaluate the effectiveness of eggshell powder as a bone substitute for filling bone defects around CpTi-coated implants coated with nanocrystalline calcium sulfate. Materials and Methods. Eighty screw implant designs were used in the tibiae of 20 white New Zealand rabbits. A total of uncoated 20 s

This research investigates manganese (Mn) extraction from Electric Arc Furnace Steel Slag (EAFS) by using the Liquid-liquid extraction (LLE) method. The chemical analysis was done on the slag using X-ray fluorescence, X-ray diffraction, and atomic absorption spectroscopy. This work consisted of two parts: the first was an extensive study of the effect of variables that can affect the leaching process rate for Mn element from slag (reaction time, nitric acid concentration, solid to liquid ratio, and stirring speed), and the second part evaluates the extraction of Mn element from leached solution. The results showed the possibility of leaching 83.5 % of Mn element from the slag at a temperature of 25°C, nitric acid co

The complexity and partially defined nature of jet grouting make it hard to predict the performance of grouted piles. So the trials of cement injection at a location with similar soil properties as the erecting site are necessary to assess the performance of the grouted piles. Nevertheless, instead of executing trial-injected piles at the pilot site, which wastes money, time, and effort, the laboratory cement injection devices are essential alternatives for evaluating soil injection ability. This study assesses the performance of a low-pressure laboratory grouting device by improving loose sandy soil injected using binders formed of Silica Fume (SF) as a chemical admixture (10% of Ordinary Portland Cement OPC mass) to di

In this study, the flexural performance of a new composite beam–slab system filled with concrete material was investigated, where this system was mainly prepared from lightweight cold-formed steel sections of a beam and a deck slab for carrying heavy floor loads as another concept of a conventional composite system with a lower cost impact. For this purpose, seven samples of a profile steel sheet–dry board deck slab (PSSDB/PDS) carried by a steel cold-formed C-purlins beam (CB) were prepared and named “composite CBPDS specimen”, which were tested under a static bending load. Specifically, the effects of the profile steel sheet (PSS) direction (parallel or perpendicular to the span of the specimen) using different C-purlins c

This paper presents the implementation of a complex fractional order proportional integral derivative (CPID) and a real fractional order PID (RPID) controllers. The analysis and design of both controllers were carried out in a previous work done by the author, where the design specifications were classified into easy (case 1) and hard (case 2) design specifications. The main contribution of this paper is combining CRONE approximation and linear phase CRONE approximation to implement the CPID controller. The designed controllers-RPID and CPID-are implemented to control flowing water with low pressure circuit, which is a first order plus dead time system. Simulation results demonstrate that while the implemented RPID controller fails to stabi
