Barakat, American Middle East Relief, to Fayez Sayegh, October 18, 1950 and November 19, 1950; Sayegh\u27s response, November 24, 1950; letter from the Immigration & Naturalization Service to Sayegh, December 12, 1950; about Sayegh\u27s application for adjustment of status as a displaced person residing in the United States
Of the Freedom Famine in Palestine
No full textIn this searing essay, poet and author Ibtisam Barakat bears witness to what she names the “Freedom Famine” in Gaza—a deliberate, decades-long deprivation of basic human rights culminating in the catastrophic conditions of 2025. Writing from the United States while in conversation with Gazan author Omar Hammash, Barakat juxtaposes their drastically unequal realities: her safety and his daily encounters with death, displacement, and starvation. Through Hammash’s testimony—delivered amid constant bombardment and interrupted by news of a friend’s killing—Barakat documents the collapse of Gaza’s infrastructure, the mass targeting of aid workers, the lethal failures of international relief, and the killing of journalists that has rendered Palestinians\u27 suffering largely unseen. She situates the genocide within a longer history of siege, occupation, and the systematic stripping of Palestinian sovereignty, challenging global indifference and the political weaponization of humanitarian language. The essay argues that freedom, like food or water, is a human necessity—and that Palestinians have been starved of it for generations. Yet Barakat insists on the enduring power of writing to resist erasure, transforming trauma into testimony and forging a literary space in which Palestinian humanity can be affirmed against all attempts to silence it
Decomposing Total Factor Productivity Change of Cotton Cultivars (Barakat-90 and Barac (67)B) in the Gezira Scheme (1991 – 2007) Sudan
Full text linkThe main objective of this paper was to decompose Total Factor Productivity Change (TFPCH) of cotton cultivars Barakat-90 and Barac(67)B in the Gezira scheme in 1991-2007, based on Data Envelopment Analysis Program (DEAP) Software Version 2.1, using model of input–oriented Malmquist indices Total Factor Productivity (TFP). This model could give meaningful results regarding technological and economic behavior relationship over time using balance panel data on Barac(67)B and Barakat-90 cultivars, Relevant secondary data were collected and analyzed to meet the stated objectives. This paper was aimed to decompose TFPCH into two components Technological Change (TECH) and Technical Efficiency Change (EFCH) and the latter was further divided into Scale Efficiency Change (SEFCH) and Pure Efficiency Change (PEFCH). The methodology allowed the recovery of various efficiency and productivity measures. The paper was mainly to answer the questions related to technical efficiency, scale efficiency and productivity changes. In the study on cotton cultivars, the innovation was improving up and down of TECH over time. Scale inefficiency was the main problem in efficiency analysis and mainly due to production operating at increasing returns to scale in Barac(67)B and Barakat-90 operating at constant return to scale. TFPCH was -1.3%, the contribution of EFCH was -1.6% and TECH was 0.30%, the main problem was efficiency change and this was mainly due to scale inefficiency, Barac(67)B contributed to this negative at an average annual rate -3.3%. This implying that the Barac(67)B was ailing due to efficiency change. The study has recommended, substantial improvement in knowledge about productivity and efficiency using scientific approaches, the scheme administration should take full advantage of Barac(67)B cultivar to be extensively grown, Barakat-90 requires further investigation benefiting from technological innovation, additional, improvement in agricultural processing to increase the value added, and the benefit of scientific breakthrough in agricultural science are also recommended.Crop Production/Industries,

Decomposing Total Factor Productivity Change of Cotton Cultivars (Barakat-90 and Barac (67)B) in the Gezira Scheme (1991 – 2007) Sudan
Full text linkThe main objective of this paper was to decompose Total Factor Productivity Change
(TFPCH) of cotton cultivars Barakat-90 and Barac(67)B in the Gezira scheme in
1991-2007, based on Data Envelopment Analysis Program (DEAP) Software Version
2.1, using model of input–oriented Malmquist indices Total Factor Productivity
(TFP). This model could give meaningful results regarding technological and
economic behavior relationship over time using balance panel data on Barac(67)B and
Barakat-90 cultivars, Relevant secondary data were collected and analyzed to meet
the stated objectives. This paper was aimed to decompose TFPCH into two
components Technological Change (TECH) and Technical Efficiency Change
(EFCH) and the latter was further divided into Scale Efficiency Change (SEFCH) and
Pure Efficiency Change (PEFCH). The methodology allowed the recovery of various
efficiency and productivity measures. The paper was mainly to answer the questions
related to technical efficiency, scale efficiency and productivity changes. In the study
on cotton cultivars, the innovation was improving up and down of TECH over time.
Scale inefficiency was the main problem in efficiency analysis and mainly due to
production operating at increasing returns to scale in Barac(67)B and Barakat-90

administration should take full advantage of Barac(67)B cultivar to be extensively grown, Barakat-90 requires further investigation benefiting from technological

Enhancing IEEE 802.11MAC in congested environments
Full text linkIEEE 802.11 is currently the most deployed wireless local area networking standard. It uses carrier sense multiple access with collision avoidance (CSMA/CA) to resolve contention between nodes. Contention windows (CW) change dynamically to adapt to the contention level: Upon each collision, a node doubles its CW to reduce further collision risks. Upon a successful transmission, the CW is reset, assuming that the contention level has dropped. However, the contention level is more likely to change slowly, and resetting the CW causes new collisions and retransmissions before the CW reaches the optimal value again. This wastes bandwidth and increases delays. In this paper we analyze simple slow CW decrease functions and compare their performances to the legacy standard. We use simulations and mathematical modeling to show their considerable improvements at all contention levels and transient phases, especially in highly congested environments
