AI Article Synopsis
- ICT currently contributes an estimated 1.8%-2.8% to global greenhouse gas emissions, and this could range from 2.1% to 3.9% when accounting for supply chain factors.
- Major reductions in ICT emissions will require significant political and industrial cooperation, as analysts generally agree that these emissions will not decline without such efforts.
- The paper argues that, without global carbon constraints and a new regulatory framework, the ICT sector's emissions are likely to continue increasing, and many carbon pledges are insufficient to meet climate goals set by the Paris Agreement.
Article Abstract
In this paper, we critique ICT's current and projected climate impacts. Peer-reviewed studies estimate ICT's current share of global greenhouse gas (GHG) emissions at 1.8%-2.8% of global GHG emissions; adjusting for truncation of supply chain pathways, we find that this share could actually be between 2.1% and 3.9%. For ICT's future emissions, we explore assumptions underlying analysts' projections to understand the reasons for their variability. All analysts agree that ICT emissions will not reduce without major concerted efforts involving broad political and industrial action. We provide three reasons to believe ICT emissions are going to increase barring intervention and find that not all carbon pledges in the ICT sector are ambitious enough to meet climate targets. We explore the underdevelopment of policy mechanisms for enforcing sector-wide compliance, and contend that, without a global carbon constraint, a new regulatory framework is required to keep the ICT sector's footprint aligned with the Paris Agreement.

Heterogeneity across Australian ICT policies for education of gifted students.

This paper critically evaluates the current status of Information and Communication Technology (ICT) policies for gifted education in Australia, highlighting the lack of a comprehensive understanding and analysis of the heterogeneity across these policies. Despite the increasing recognition of the importance of ICT's importance in meeting the unique needs of gifted learners, there is a dearth of research systematically investigating the variations in policy frameworks, approaches to ICT integration, and their impact on educational outcomes for gifted students. This research problem necessitates an in-depth exploration of the heterogeneous nature of Australian ICT policies and their implications for promoting equitable access and fostering effective educational experiences.

Background: Renal injury in transfusion dependent β thalassemia patients (TDT) has been attributed to iron overload, chronic anemia and iron-chelation therapy (ICT) toxicity. We studied renal function in TDT patients treated with two different ICT regimes.
Patients And Methods: We studied 36 TDT patients: 26 received deferasirox (DFX) and 10 were treated with deferoxamine (DFO) +/- deferiprone (DFP).

Breast cancer is one of the most common cancers in women, with more than 1,300,000 cases and 450,000 deaths each year worldwide. In this context, recent studies showed that early breast cancer detection, along with suitable treatment, could significantly reduce breast cancer death rates in the long term. X-ray mammography is still the instrument of choice in breast cancer screening.

The colorectal cancer (CRC) is one leading contributor of cancer-related mortality worldwide. The search for effective anti-CRC agents is valuable. In the current study, we showed that icaritin (ICT), an active natural ingredient from the Chinese plant Epimedium, potently inhibited proliferation and survival of established (HT-29, HCT-116, DLD-1, and SW-620) and primary (patient-derived) CRC cells.
