This paper employs the feminist educational leadership perspective to analyse the ecological context and its influence on the leadership experiences of school head teachers within a patriarchal ...cultural setting. Methodology: This paper forms part of a mixed methods study that included a quantitative random survey during the first research phase to determine the leadership styles of 350 secondary school head teachers across nine districts in the Punjab province of Pakistan using the Multifactor Leadership Questionnaire. This paper is based on the second research phase that analyses empirical data from semi structured interviews of a purposive-stratified sample of 14 head teachers, selected from among the 264 survey respondents, comprising of seven males and seven females. Bronfenbrenner’s ecological development theory is employed as an analytical framework for thematic analysis. Findings: The study reveals that females must navigate gender stereotypes in a society where they have to fight to establish authority, encounter misogynistic attitudes, rely upon familial support to begin their career, gain spiritual support from a higher power, face work-family conflicts all while practicing educational leadership with high motivation. On the other hand, males assume themselves to be natural leaders and appear to be spared from ecological challenges that impede their leadership journeys. Implications: The findings confirm the prevalence of gender stereotypes that position leadership within the masculine domain in a patriarchal context. The study proposes a complete restructuring of the socio-cultural framework to create a gender neutral society that provides equal educational and professional opportunities to all social members in order to maximize human capital development that is crucial for a country’s economic progress. The findings reflect several subtle and non-subtle socio-cultural challenges faced by female leaders around the world. Originality – This study contributes to enhancing the literature on gender and educational leadership in a patriarchal cultural context.
Mitigation of channel unfavorable circumstances during data routing in underwater wireless sensor networks (UWSNs) has utmost significance. It guarantees saving packet corruption along unfavorable ...channels so that vital data is not lost or become meaningless. This paper proposes two routing protocols for UWSNs: localization free energy efficient routing (LFEER) and its improved version, localization free energy efficient cooperative routing (Co-LFEER). The LFEER makes decision of choosing a relay based on its maximum residual energy, number of hops and the bit error rate of the link over which packets are transmitted. These metrics are chosen to save packets from corruption to the maximum limit and maintain stable paths (where nodes do not die soon). Since a single link is used in the LFEER for packets forwarding, the link may become worse with changing circumstances of the channel. To deal with this issue, cooperative routing is added to the LFFER to construct the Co-LFEER protocol, in which some copies of packets are received by destination to decide about packets quality. Converse to some prevalent protocols, both LFEER and Co-LFEER are independent of knowing the sensor nodes’ positions, which increases computational complexity and wasteful utilization of resources. Based on extensive simulations, the proposed schemes are better than Co-DBR in reducing energy utilization and advancing packets to the desired destination.
The promised paradises of colonial capitalism and neoliberalism are set in a perpetually elusive future (Fitzpatrick
1992
). This future is not a set destination, but an endless linear journey set to ...the thrum of ‘progress’ and ‘development’. This paper considers, in the context of recent cases relating to development in the Athabasca tar sands region, what the law of the Canadian settler state does when it is faced with interruptions and ruptures in its timescape. Drawing on Fitzpatrick’s seminal work,
The Mythology of Modern Law
, I argue that a conceptualisation of law’s behaviour in these contexts as functionally mythological highlights some of the elusive ways that settler law maintains a stranglehold over legal imaginaries of oil and gas developments: by distorting and flattening the pasts and presents of Indigenous societies that pre-dated (and continue to co-exist with) the settler state on ‘Canadian’ land, by mediating between the ‘origin’ of the settler state and the daily rhythms of colonial time through ‘Eternal Objects’ such as property and economic development, and by asserting a general ‘objectivity’ of law to evade any direct grappling with the stark possibilities of the ‘end of the world’ created by the climate crisis. I conclude, drawing on Indigenous scholarship and the work of de Goede and Randalls, that a meaningful response to the climate crisis requires re-enchanted attachments to life that necessitate a departure from the one-dimensional temporality of the mythologies of settler law.
The promising chemical, mechanical, and electrical properties of silver from nano scale to bulk level make it useful to be used in a variety of applications in the biomedical and electronic fields. ...Recently, several methods have been proposed and applied for the small-scale and mass production of silver in the form of nanoparticles, nanowires, and nanofibers. In this research, we have proposed a novel method for the fabrication of silver nano fibers (AgNFs) that is environmentally friendly and can be easily deployed for large-scale production. Moreover, the proposed technique is easy for device fabrication in different applications. To validate the properties, the synthesized silver nanofibers have been examined through Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Further, the synthesized silver nanofibers have been deposited over sensors for Relative humidity (RH), Ammonia (NH
), and temperature sensing applications. The sensor was of a resistive type, and found 4.3 kΩ for relative humidity (RH %) 30-90%, 400 kΩ for NH
(40,000 ppm), and 5 MΩ for temperature sensing (69 °C). The durability and speed of the sensor verified through repetitive, response, and recovery tests of the sensor in a humidity and gas chamber. It was observed that the sensor took 13 s to respond, 27 s to measure the maximum value, and took 33 s to regain its minimum value. Furthermore, it was observed that at lower frequencies and higher concentration of NH
, the response of the device was excellent. Furthermore, the device has linear and repetitive responses, is cost-effective, and is easy to fabricate.
Background: Diabetes mellitus has become a major public health problem globally. Social media could be useful in assisting clinical practice and sharing health-related information to improve ...self-management and to promote a positive behavioural change. This study aims to develop a guide on the best online tools by determining the media preference reflected by health- related information received from social media amongst diabetic patients in Hospital Canselor Tuanku Muhriz (HCTM), Universiti Kebangsaan Malaysia, Kuala Lumpur.
Methods: This study was conducted cross-sectional on 174 respondents, who were selected by using a simple random sampling method. Socio-demographic data and the use of the internet and media for health-related information were obtained via questionnaires.
Results: The most preferred social media used for searching and sharing health-related information was WhatsApp (73.6%), followed by Facebook (67.8%), Instagram (18.4%) and Twitter (17.2%). The social media preference related to socio-demographic data of age was statistically significant (P < 0.002), which had a medium effect. Furthermore, the media preference was not significantly related to health-related information searched or shared on social media and the frequency of usage.
Conclusion: Indeed, the social media have been an essential media platform to enhance public awareness concerning public health. This calls for evolution to further enhance the use of social media amongst healthcare practitioners to emphasise health promotion and empower the patients to play an active role in their healthcare. This study provides a guideline for the medical researchers, practitioners or healthcare providers in choosing WhatsApp as an online medium to communicate with diabetic patients in the future, specifically in Malaysia.
Designing an efficient, reliable, and stable algorithm for underwater acoustic wireless sensor networks (UA-WSNs) needs immense attention. It is due to their notable and distinctive challenges. To ...address the difficulties and challenges, the article introduces two algorithms: the multilayer sink (MuLSi) algorithm and its reliable version MuLSi-Co using the cooperation technique. The first algorithm proposes a multilayered network structure instead of a solid single structure and sinks placement at the optimal position, which reduces multiple hops communication. Moreover, the best forwarder selection amongst the nodes based on nodes’ closeness to the sink is a good choice. As a result, it makes the network perform better. Unlike the traditional algorithms, the proposed scheme does not need location information about nodes. However, the MuLSi algorithm does not fulfill the requirement of reliable operation due to a single link. Therefore, the MuLSi-Co algorithm utilizes nodes’collaborative behavior for reliable information. In cooperation, the receiver has multiple copies of the same data. Then, it combines these packets for the purpose of correct data reception. The data forwarding by the relay without any latency eliminates the synchronization problem. Moreover, the overhearing of the data gets rid of duplicate transmissions. The proposed schemes are superior in energy cost and reliable exchanging of data and have more alive and less dead nodes.
In recent years, cloud computing has gained massive popularity in information technology and the industrial Internet of things. It provides facilities to the users over the wireless channel. Many ...surveys have been carried out in cloud security and privacy. The existing survey papers do not specify the classifications on the basis of cloud computing components. Therefore, they fail to provide the techniques with their specialities as well as the previously available literature review is outdated. This paper presents the security for cloud computing models with a new aspect. Unlike the previously existing surveys, the literature review of this paper includes the latest research papers in the field of cloud security. Also, different classifications are made for cloud computing security on the basis of different cloud components that are used to secure the cloud models. Furthermore, a total of eleven (11) classifications are considered, which includes cloud components to secure the cloud systems. These classifications help the researchers to find out the desired technique used in a specific component to secure the cloud model. Moreover, the shortcoming of each component enables the researchers to design an optimal algorithm. Finally, future directions are given to highlight future research challenges that give paths to researchers.
