    This study aims to describe the journey of Islamic education in universities in the border province of southern Thailand and how they respond to the global crisis. Is research with a qualitative approach to ethnographic methods of Realist ethnography, which is an objective view of information learned in the field and usually uses a third-person point of view. Data sources were obtained through interviews, field observations, and sociocultural phenomena. Based on the study of researchers, the results of the study concluded that the journey of Islamic education in ASEAN countries including the Southern Border Province of Thailand both Muslim majority and minority can be divided into four phases sequentially. First phase is the introduction phase. Second phase is when Islamic education faces external and global challenges. The third phase is when Islamic education is strong enough to face challenges and be able to solve problems. Fourth phase, Islamic education will provide all the solutions for the global crisis. By looking at the phases of the Journey of Islamic Education in Higher Education in the Southern Border Province of Thailand, will be able to provide all solutions for the global crisis.

    CARDS: A Collaborative Community Model for Faculty Development or an Institutional Case Study of Writing Program Administration

    Get PDF
    The structure of writing programs evolves to account for the transformation of composition studies. Online and dual credit programs necessitate a need to adjust prior practices initially geared towards face-to-face pedagogy; however, several challenges surface in online and dual credit writing programs. The most prevalent is that these online courses are primarily staffed by non-tenured faculty, including adjuncts who do not have a physical presence on campus. The faculty dynamic presents many challenges when attempting to garner participation in collaborations. In recent years, the Writing Program Administrator (WPA) at a regional public university noticed a need to improve faculty morale, satisfaction, and participation, especially with the emergence of online programs. Through a national survey and selective interviews of current faculty at the university, we determined that the answer lies in the structure of the program. The Writing Program Administrator has several models to choose from, but we will argue that the collaborative community model is most conducive to addressing and enhancing faculty morale, satisfaction, and participation in first-year writing programs

    Technology, organization and materiality: Reflections on the Problem of Agency

    Get PDF
    In management and information systems research, there has been a long-standing debate over the relationship between technology and the organization in which it is embedded. This debate flares up periodically and this is one such time. At one extreme is technological determinism, which makes the claim that technology is the cause and organizational change is the effect. At the other extreme is social determinism, which claims that social action and interaction is the cause and technological change is the effect. Is there a way out of this debate? How can we make sense of the interactions between people and machines? In this paper, we will examine the debate, discuss what is at stake in its resolution and explore an alternative

    Nowadays, g)obaJ wawiog hav~ ~n an jnt~mational jssu~s and world problem. Global warming happens due to the continuing rise in the average temperature of Earth~s atmosphere and oceans. It is because of increased concentrations of greenhouse gases in the atmosphere, resulting from human activities such as deforestation and burning of fossil fuels. These activities contribute to the C02 gasses emissions. Finding has made by IPCC SRES in year 1990 to 2010, the caroon emission increased by year from 21 to 31 (billion tons per year). In order to reduce the heat, a few campaign was conduct and rehabilitation work been done. Every sector in industries especially in building construction they also contribute to the gasses emission by energy consumed by human for living and working. Based on case study, buildings consume one-third of the world energy and worldwide building energy consumption is expected to grow by 45% from year 2002 to year 2025. As in tropical countries experience high levels of heat radiation from the sun and leads to discomfort to humans and surroundings. Air conditioning is widely used to encounter this problem, which consumes high levels of energy. Therefore, this research aims to quantity the reduction in indoor temperature and to verity the positive effect of installing reflective insulation in roofs on indoor parameters. The research methodology consist of I) construction of 2 down -scale model of experimental house (600 x 600 x 500mm) to study the effect of reflective insulation of indoor temperature and 2) insulation material 3) Roof color and 4 ) the house allocated. Data collection is conducted every hour from Sam to 5pm for seven days. The result shows that the insulated houses quantify the most reduction with 37.69"/o and the reduction of temperature difference is at 10.27%. From the result, the behavior of parameters measured show that insulated house has a better thermal performance compared to the coritrol house. ln future it is important to implement a cool roof to preserve our nature and sustainability development

    Nuclear and Neutron Matter Calculations with Different Model Spaces

    In this work we investigate the so-called model-space Brueckner-Hartree-Fock (MBHF) approach for nuclear matter as well as for neutron matter and the extension of this which includes the particle-particle and hole-hole (PPHH) diagrams. A central ingredient in the model-space approach for nuclear matter is the boundary momentum kMk_M beyond which the single-particle potential energy is set equal to zero. This is also the boundary of the model space within which the PPHH diagrams are calculated. It has been rather uncertain which value should be used for kMk_M. We have carried out model-space nuclear matter and neutron matter calculations with and without PPHH diagrams for various choices of kMk_M and using several modern nucleon-nucleon potentials. Our results exhibit a saturation region where the nuclear and neutron matter matter energies are quite stable as kMk_M varies. The location of this region may serve to determine an "optimum" choice for kMk_M. However, we find that the strength of the tensor force has a significant influence on binding energy variation with kMk_M. The implications for nuclear and neutron matter calculations are discussed.Comment: 24 pages, Elsevier LaTeX style, 17 figs include

    Get PDF
    The syntheses of a range of enantiopure organosulfur donors with hydrogen bonding groups are described including TTF related materials with two, four, six and eight hydroxyl groups and multiple stereogenic centres and a pair of chiral N-substituted BEDT-TTF acetamides. Three charge transfer salts of enantiopure poly-hydroxy-substituted donors are reported, including a 4:1 salt with the meso stereoisomer of the dinuclear [Fe2(oxalate)5 ]4- anion in which both cation and anion have chiral components linked together by hydrogen bonding, and a semiconducting salt with triiodide

    Azumaya Objects in Triangulated Bicategories

    Full text link
    We introduce the notion of Azumaya object in general homotopy-theoretic settings. We give a self-contained account of Azumaya objects and Brauer groups in bicategorical contexts, generalizing the Brauer group of a commutative ring. We go on to describe triangulated bicategories and prove a characterization theorem for Azumaya objects therein. This theory applies to give a homotopical Brauer group for derived categories of rings and ring spectra. We show that the homotopical Brauer group of an Eilenberg-Mac Lane spectrum is isomorphic to the homotopical Brauer group of its underlying commutative ring. We also discuss tilting theory as an application of invertibility in triangulated bicategories.Comment: 23 pages; final version; to appear in Journal of Homotopy and Related Structure

    Automatic correction of hand pointing in stereoscopic depth

    Get PDF
    In order to examine whether stereoscopic depth information could drive fast automatic correction of hand pointing, an experiment was designed in a 3D visual environment in which participants were asked to point to a target at different stereoscopic depths as quickly and accurately as possible within a limited time window (≤300 ms). The experiment consisted of two tasks: "depthGO" in which participants were asked to point to the new target position if the target jumped, and "depthSTOP" in which participants were instructed to abort their ongoing movements after the target jumped. The depth jump was designed to occur in 20% of the trials in both tasks. Results showed that fast automatic correction of hand movements could be driven by stereoscopic depth to occur in as early as 190 ms.This work was supported by the Grants from the National Natural Science Foundation of China (60970062 and 61173116) and the Doctoral Fund of Ministry of Education of China (20110072110014)

    Deletion of the hemopexin or heme oxygenase-2 gene aggravates brain injury following stroma-free hemoglobin-induced intracerebral hemorrhage

    BACKGROUND: Following intracerebral hemorrhage (ICH), red blood cells release massive amounts of toxic heme that causes local brain injury. Hemopexin (Hpx) has the highest binding affinity to heme and participates in its transport, while heme oxygenase 2 (HO2) is the rate-limiting enzyme for the degradation of heme. Microglia are the resident macrophages in the brain; however, the significance and role of HO2 and Hpx on microglial clearance of the toxic heme (iron-protoporphyrin IX) after ICH still remain understudied. Accordingly, we postulated that global deletion of constitutive HO2 or Hpx would lead to worsening of ICH outcomes. METHODS: Intracerebral injection of stroma-free hemoglobin (SFHb) was used in our study to induce ICH. Hpx knockout (Hpx(−/−)) or HO2 knockout (HO2(−/−)) mice were injected with 10 μL of SFHb in the striatum. After injection, behavioral/functional tests were performed, along with anatomical analyses. Iron deposition and neuronal degeneration were depicted by Perls’ and Fluoro-Jade B staining, respectively. Immunohistochemistry with anti-ionized calcium-binding adapter protein 1 (Iba1) was used to estimate activated microglial cells around the injured site. RESULTS: This study shows that deleting Hpx or HO2 aggravated SFHb-induced brain injury. Compared to wild-type littermates, larger lesion volumes were observed in Hpx(−/−) and HO2(−/−) mice, which also bear more degenerating neurons in the peri-lesion area 24 h postinjection. Fewer Iba1-positive microglial cells were detected at the peri-lesion area in Hpx(−/−) and HO2(−/−) mice, interestingly, which is associated with markedly increased iron-positive microglial cells. Moreover, the Iba1-positive microglial cells increased from 24 to 72 h postinjection and were accompanied with improved neurologic deficits in Hpx(−/−) and HO2(−/−) mice. These results suggest that Iba1-positive microglial cells could engulf the extracellular SFHb and provide protective effects after ICH. We then treated cultured primary microglial cells with SFHb at low and high concentrations. The results show that microglial cells actively take up the extracellular SFHb. Of interest, we also found that iron overload in microglia significantly reduces the Iba1 expression level and resultantly inhibits microglial phagocytosis. CONCLUSIONS: This study suggests that microglial cells contribute to hemoglobin-heme clearance after ICH; however, the resultant iron overloads in microglia appear to decrease Iba1 expression and to further inhibit microglial phagocytosis
