Mobile Learning Services Acceptance Model Among Malaysian Higher Education Students
Mobile learning (m-learning) is considered as the next form of e-learning using mobile technologies to facilitate education for teachers and learners anywhere and anytime. Engaging the m-learning services in the Malaysian higher education could improve the availability of education. Studentsâ awareness of such technology is a key for success acceptance. This research aims to study the acceptance and use of m-learning services among Malaysian higher education students. The main objective is to propose a students' acceptance model of m-learning in the higher education environment. The study investigates the studentsâ acceptance of behavior intention to use m-learning and its effect on usage behavior in the higher education environment. It provides the knowledge base about the current state of studentsâ awareness about m-learning services. The study found that both of the environment and the infrastructure are appropriate to diffuse and utilize m-learning in the higher education environment. Furthermore, the results showed that the students have adequate knowledge and awareness to use such technology in their education environment. The limitations of m-learning for education were well concerned by students. The studentsâ perspective is very important to investigate the use behavior of m-learning in the higher education environment. Findings of the study suggest that the behavior intention to use the m-learning by students in the higher education environment have positive influence on the use behavior. Consequently, the availability of facilitating conditions is an important to influence studentsâ use behavior. The study suggests several factors as important determinants of the behavior intention to use the m-learning in the higher education environment. Specifically, behavior intension to use appears to be adopted and facilitated by the usefulness of m-learning services, so more usefulness of m-learning leads to more acceptances among students in the higher educatio

Mobile-based library loan service(MBLLS)
Most libraries provide book reservation and renewal services through the library counter as well as online computer.However, through the counter, these services are only available during of ice hours.Even though through online computer, users are able to access the services anytime, but they must be connected to the Internet which
limits their access to these services.Since the need of library users have increased tremendously, an alternative technology is required.Thus, mobile technology has been identified as a potential alternative since it is able to provide the two services anytime and anywhere.This paper discusses a prototype Mobile-Based Library Loan Service (MBLLS), a facility which has been developed for library users to access online library services through mobile devices. MBLLS was developed for book reservation and renewal services. Results of user evaluation on the MBLLS indicate that it has good usability in terms of Usefulness, Ease of Use and Outcome/Future Use.The results also indicate that there is a significant dif erence between novice and expert users for Usefulness and Ease of Use, while no significant dif erence for Outcome/Future Use
A Systematic Review of the Critical Factors for Success of Mobile Learning in Higher Education (University Students\u27 Perspective)
The phenomenon of the use of a mobile learning (m-Learning) platform in educational institutions is slowly gaining momentum. However, the enthusiasm with which mobile phones have been welcomed into every aspect of our lives is not yet apparent in the educational sector. To understand the reason, it is important to understand user expectations of the system. This article documents a systematic review of existing studies to find the success factors for effective m-Learning. Our systematic review collates results from 30 studies conducted in 17 countries, where 13 critical success factors were found to strongly impact m-Learning implementation. Using these results within the framework of the diffusion of innovation model for innovation adoption and the critical success factors together help us see what aspects of the innovation decision process are the likely causes of the reduced take-up of m-Learning by university students
Factors affecting the use of smart mobile examination platforms by universitiesâ postgraduate students during the COVID 19 pandemic : an empirical study
Recent years have seen an increasingly widespread use of online learning technologies. This has prompted universities to make huge investments in technology to augment their position in the face of extensive competition and to enhance their studentsâ learning experience and efficiency. Numerous studies have been carried out regarding the use of online and mobile phone learning platforms. However, there are very few studies focusing on how university students will accept and adopt smartphones as a new platform for taking examinations. Many reasons, but most recently and importantly the COVID-19 pandemic, have prompted educational institutions to move toward using both online and mobile learning techniques. This study is a pioneer in examining the intention to use mobile exam platforms and the prerequisites of such intention. The purpose of this study is to expand the Technology Acceptance Model (TAM) by including four additional constructs: namely, content quality, service quality, information quality, and system quality. A self-survey method was prepared and carried out to obtain the necessary basic data. In total, 566 students from universities in the United Arab Emirates took part in this survey. Smart PLS was used to test the study constructs and the structural model. Results showed that all study hypotheses are supported and confirmed the effect of the TAM extension factors within the UAE higher education setting. These outcomes suggest that the policymakers and education developers should consider mobile exam platforms as a new assessment platform and a possible technological solution, especially when considering the distance learning concept. It is good to bear in mind that this study is initial and designed to explore using smartphones as a new platform for student examinations. Furthermore, mixed-method research is needed to check the effectiveness and the suitability of using the examination platforms, especially for postgraduate higher educational levels
Cementitious binders for construction in northern cold regions
Abstract
The construction season in northern regions is shortened by the severe cold weather, which also considerably reduce the performance and quality of cementitious materials. The construction season is currently extended using various methods, such as the installation of heating/insulation systems, the use of high-early-strength cement, and the avoidance of the use of ecofriendly supplementary cementitious materials (SCMs). These measures increase the costs, energy consumption, emissions, and complexity of winter construction. Winter maintenance work is consequently postponed frequently, thereby decelerating regional growth. Therefore, this thesis aims to develop sustainable cementitious materials for northern cold regions with maximum utilization of SCMs and minimum use of heating systems.
A comparable 28-day compressive strength can be attained in the ordinary Portland cement (OPC)-based binder cured at â10 °C to that at 20 °C, which can be attributed to the combined effects of calcium silicate hydrate (CâSâH) seeds, a binary antifreeze admixture, and room-temperature (23 °C ± 1 °C) precuring. Moreover, 30 wt.% of OPC in the 0 °C-cured binders could be substituted with ground granulated blast-furnace slag by the addition of CâSâH seeds. This replacement level can be increased to 50 wt.% with the use of GGBFS pre-alkali activation treatment. The calcium sulfoaluminate belite ferrite (CSABF) cement works effectively as an ecofriendly mineral accelerator, assuring the strength development of the OPC/CSABF blend at extremely low ambient temperatures (i.e., â25 °C). The results of this thesis demonstrate the potential for extending the construction season in northern regions using more sustainable cementitious materials while reducing the requirement for expensive and energy-consuming heating systems during winter construction work.TiivistelmĂ€
Pohjoisten alueiden rakennuskautta lyhentÀÀ ankara kylmÀ sÀÀ, joka myös heikentÀÀ huomattavasti betonin laatua. Rakennuskautta pidennetÀÀn tÀllÀ hetkellÀ erilaisilla menetelmillÀ, kuten lÀmmitys-/eristysjÀrjestelmien asennuksella, korkean varhaisen lujuuden omaavan sementin kÀytöllÀ ja sementtiÀ korvaavien materiaalien (SCM) kÀytön vÀlttÀmisellÀ. NÀmÀ toimenpiteet lisÀÀvÀt talvirakentamisen kustannuksia, energiankulutusta, ja CO2-pÀÀstöjÀ, ja monimutkaistavat rakentamista. NÀin ollen talvikrakentamista lykÀtÀÀn usein, mikÀ hidastaa alueellista kasvua. Siksi tÀmÀn opinnÀytetyön tavoitteena on kehittÀÀ kestÀviÀ sementtimÀisiÀ sideaineitaa pohjoisille kylmille alueille hyödyntÀmÀllÀ mahdollisimman paljon sementtiÀ korvaavia ympÀristöystÀvÀllisiÀ sideaineita ja kÀyttÀmÀllÀ mahdollisimman vÀhÀn lÀmmitysjÀrjestelmiÀ.
Tavalliselle, Portland-sementtipohjaiselle (OPC) sideaineelle voidaan saavutta yhtĂ€ korkea lujuus â10 °C:ssa kuin 20 °C:ssa 28 pĂ€ivĂ€n iĂ€ssĂ€, jos kĂ€ytetÀÀÀn kalsiumsilikaattihydraatti (CâSâH) -nanopartikkeleita, jÀÀtymisenestoaineita ja esikovetusta huoneenlĂ€mpötilassa (23 °C ± 1 °C). LisĂ€ksi 0 °C:ssa kovettuneissa sideaineissa 30 paino-%:a OPC:sta voitaisiin korvata jauhetulla masuunikuonalla lisÀÀmĂ€llĂ€ siihen CâSâH-nanopartikkeleita. TĂ€mĂ€ korvausaste voidaan nostaa 50 paino-%:iin kĂ€yttĂ€mĂ€llĂ€ masuunikuonan alkaliaktivaatiokĂ€sittelyĂ€. LisĂ€ksi työssĂ€ havaittiin, ettĂ€ kalsiumsulfoaluminaattibeliitti-ferriittisementti (CSABF) toimii tehokkaasti ympĂ€ristöystĂ€vĂ€llisenĂ€ mineraalikiihdyttimenĂ€ ja varmistaa OPC/CSABF-seoksen lujuuskehityksen erittĂ€in alhaisissa ympĂ€ristön lĂ€mpötiloissa (â25 °C). TĂ€mĂ€n opinnĂ€ytetyön tulokset osoittavat, ettĂ€ rakennuskautta on mahdollista pidentÀÀ pohjoisilla alueilla kestĂ€vĂ€mmillĂ€ sementtimateriaaleilla ja samalla vĂ€hentÀÀ kalliiden ja energiaa kuluttavien lĂ€mmitysjĂ€rjestelmien tarvetta talvibetonoinnin aikana

Low-temperature (-10 °C) curing of Portland cement paste â synergetic effects of 1 chloride-free antifreeze admixture C-S-H seeds, and room-temperature pre-curing
Cold weather drastically shortens the construction season in northern regions. Low ambient temperatures are known to have detrimental impacts on the reactivity and hardened performance of cementitious materials. This study therefore aims to assess the combined impacts of calcium silicate hydrate (C-S-H) seeds, binary chloride-free antifreeze admixture (i.e., urea and calcium nitrate), and short-period precuring at room temperature (23±1 °C) on ordinary Portland cement (OPC) paste-cured at -10 °C. The heat of hydration, setting time, compressive strength, freezing point, frozen water amount, hydration products precipitation rate, water absorption, and permeable porosity were investigated experimentally. The best results in terms of compressive strength, degree of hydration, water absorption, and permeable porosity were obtained when C-S-H seeds, antifreeze admixture, and precuring were combined due to their mutual impacts. In the absence of room-temperature precuring, C-S-H seeds additive and antifreeze admixture showed negligible acceleration impacts on compressive strength development of subzero-cured paste. The incorporation of seeds and antifreeze admixture decreased the freezing points of the binders and thus protected the admixed binders against frost damage, and their effects were more obvious when combined with a few hours of precuring. The compressive strength of 28 d-old OPC paste modified by C-S-H seeds and antifreeze admixture and treated with precuring developed rapidly at -10 °C, gaining 96% (75.1 MPa) of that measured in control paste cured at room temperature (78 MPa), with comparable durability properties and a significant reduction of energy consumption and CO2 emissions.publishedVersio
