    Examining The Effectiveness Of Writer’s Workshop And Interactive Writing On Preschool Emergent Writing And Attitude In The Northwest Zone Of Nigeria

    No full text
    Preschool children hold immense writing potential that is rarely realized in traditional classrooms. This mixed-method, the quasi-experimental study focused on how best to teach these emergent writers. Comparing the effects of Interactive Writing and Writer’s Workshop instruction, the study provided a clearer picture of how these instructional approaches influence children’s emergent writing achievement and attitudes

    Passive Rule-Based Approach To Detect Sinkhole Attack In 6lowpan Rpl Based Internet Of Things Networks

    No full text
    The aim of this thesis is to propose a Passive Rule-Based Approach named PRBA to detect sinkhole attacks in 6LoWPAN RPL-based IoT Networks, which consists of four stages to achieve four research objectives, which are: (1) Data collection and preprocessing stage that fulfills the objective to transform the collected power consumption values and the captured ICMPv6 network traffic into a meaningful format; (2) Feature Selection stage that fulfills the objective to decrease the size of the features by selecting the most significant features that contribute to detecting sinkhole attacks; (3) Behavioral Indicators stage that fulfills the objective to identify abnormal behavior of sinkhole attacks using the features of the ICMPv6 and power consumption from the previous stage; and (4) Sinkhole Attack Detection stage that fulfills the objective to decide whether there is a sinkhole attack in two steps

    Perceptions, Attitudes, And Practices Of Asthma Patients And Community Pharmacists Towards The Use Of Over-The-Counter Short-Acting Beta-2 Agonists At Community Pharmacies Of Malaysia: A Mixed Methods Approach

    No full text
    The global prevalence of asthma stands at 262 million people. Short-acting beta-2 agonists (SABA) are commonly used for asthma relief, but concerns about their overuse, especially due to the over-the-counter (OTC) availability in Malaysia, have arisen. This study investigated perceptions, attitudes, and practices of asthma patients and community pharmacists towards the use of SABA at community pharmacies of Malaysia

    The present study aims to design, synthesise, and evaluate the analgesic activities of THβC derivatives. A database of 25,227 THβC analogues was prepared from structure based virtual screening of the ZINC database for bromine fragments and linking the fragments at the N2 position of the THβC scaffold

    Characterization Of Aerophytic Oxyphototrophs Isolated From Gua Tempurung, Malaysia: Polyphasic And Biochemical Approaches

    No full text
    Caves are among the extreme oligotrophic environments with limited nutrients and low light intensity, but some aerophytic microalgae find this environment suitable for their growth and survival. Gua Tempurung is the largest limestone caves in Malaysia, but unfortunately no study was conducted on its algal diversity, taxonomic information, adaptation, physiological, and biochemical composition. This study aimed to assess the characteristics and adaptation of aerophytic oxyphototrophs isolated from Gua Tempurung

    Establishment Of Tissue Culture Planting Materials Of Ficus Carica L. Red Libyan Cultivar

    Ficus carica L. cv. Red Libyan, a member of the Moraceae family, is a cultivar of the common fig tree known for its purplish red fruit. This variety is known for its sweet and flavoursome figs, making it popular with fig lovers and gardeners. The micropropagation of Ficus carica L. cv. Red Libyan has been successfully established through a series of systematic experiments and studies. The cultivation and propagation of Ficus carica L. cv. Red Libyan can be challenging using traditional methods. This is due to factors such as slow growth, susceptibility to diseases and limited availability of planting material. In addition, a lack of optimised tissue culture protocols specifically for this variety hinders its efficient mass multiplication and genetic improvement. Therefore, the aim of this study was to develop an efficient and reproducible micropropagation protocol for this fig cultivar as well as to evaluate its morphological and genetic stability. The study included sterilisation of apical bud surfaces, regeneration of mature plantlets and in vitro propagation with different growth regulators and culture conditions. In particular, the combination of 20 μM TDZ + 1 μM NAA + 1.0 g L-1 activated charcoal medium showed the most favourable growth parameters, including shoot length, leaf number, root number and root length. Red:blue LED light was found to promote higher shoots during plantlet development. An acclimatisation protocol was successfully carried out and resulted in a 100 % survival rate of the plantlets

    Effects Of Firm Characteristics On Esg Disclosure In China: The Moderating Role Of Institutional Environment

    Get PDF
    Environment, social responsibility, and corporate governance (ESG) initiatives are considered as important business practices that assist the companies to achieve sustainable development for the business and the society. ESG activities have grown in popularity, and more companies are disclosing their ESG activities to indicate their engagement in social responsibility and to attract more investors. In China, over 40 years of economic reform have transformed the country into the biggest developing country in the world. However, although the number of listed companies in China has increased dramatically in the last decade, information transparency about their ESG activities has been lacking. The disclosure rate of independent ESG reports has remained around 25%, far lower than that of the developed Western countries. However, ESG disclosure in China is largely voluntary on the part of enterprises, and the factors influencing the motivation of corporate ESG disclosure are unclear

    The Impact Of Sex, Origin, And Attitude On The Phonological Accommodation Among University Students In Irbid

    Phonological accommodation, or phonological convergence, describes the phenomenon where individuals adjust their speech styles to align more closely with their interlocutor's speech. This thesis delves into the impact of three social variables— origin, sex, and attitudes—on phonological accommodation, using the phonological variables (q), (D), (Θ), and (ð) as indicators of salience to examine this phenomenon. A total of 60 participants were selected using a quota sampling method, and data was gathered through a structured questionnaire that is divided into four sections: demographic, identification, phonological variables use, and attitude. and in-depth interviews with twelve respondents, evenly distributed by origin and sex. The questionnaire and interview data were analyzed descriptively, while the attitude section of the questionnaire used Likert scale that rates from strongly agree (1) to strongly disagree (5). The findings revealed distinct patterns of phonological convergence. Females from rural Palestinian backgrounds showed complete convergence to the urban speech form, whereas their Horani counterparts exhibited partial convergence to the urban variety. Males from rural Palestinian backgrounds tended to adopt the Horani local variant of the (Q) variable, while remaining conservative with the other phonological variables
