    The pervasive deficit lens of multilingual language learners (MLLs) in U.S. education dehumanizes and fragments students in ways that disconnect them from their cultural and linguistic identities (CLI). MLLs are first and foremost humans with rich linguistic heritages, complex cultural backgrounds, and multiple and non-mainstream knowledges and ways of knowing (de los RĂ­os & Molina, 2020; Kasun, 2016). The deficit lens is a legacy of colonization that persists in our schools. Colonial education saw Black, Indigenous, and people of color (BIPOC) transnationals as savage and backwards with cultures and languages that needed to be erased in order for them to assimilate into dominant, mainstream U.S. culture. These colonial legacies persist in our schools today. The intent of this critical ethnographic, arts-based, youth participatory action research (YPAR) study was to explore the experiences of MLLs as they learned about and made sense of their CLI in the context of a critical multimodal, multiliteracies, ethnic studies, arts-based summer collaborative called Nuestra Escuelita. The study was framed overall by a decolonizing framework through which the researcher sought to address the persisting colonial legacies in schools and their fragmenting and dehumanizing effects on MLL students. The participants were fourteen high school, bilingual, Latinx MLLs. The overarching assertion is that the students experienced a decolonial journey towards healing, wholeness, and humanity. Specifically, this journey is reflected in the four findings: 1) feeling connections of community and care; 2) reweaving the tapestries of their identities and heritage; 3) activating critical consciousness through historical learnings, shadow work and shifts toward power; and 4) feeling inspiration for change and imagining a decolonial vision for new educational futures. These findings represent the students’ experiences, and their journey mirrored the seven stages of AnzaldĂșa’s (2015) conocimiento. Implications include centering MLLs’ CLI in curriculum and the need for implementing ethnic studies programs for the New Latinx/Global South youth

    Background: Improving access to sexual healthcare is a priority in the UK, especially for ethnic minorities. Though South Asians in the UK report low levels of sexual ill health, few data exist regarding their use of genitourinary medicine (GUM) services. Objectives: To describe reasons for attendance at GUM clinics among individuals of South Asian origin relative to patients of other ethnicities. Methods: 4600 new attendees (5% South Asian; n=226) at seven sociodemographically and geographically contrasting GUM clinics across England completed a questionnaire between October 2004 and March 2005, which were linked to routine clinical data. Results: South Asians were more likely than other groups to be signposted to the GUM clinic by another health service-for example, in women 14% versus 8% respectively (p=0.005) reported doing so from a family planning clinic. These women also reported that they would be less likely to go to the clinic if their symptoms resolved spontaneously compared with other women (51% vs 31%, p=0.024). However, relative to other clinic attendees, no differences in the proportions of South Asians who had acute STI(s) diagnosed at clinic were noted. Furthermore, South Asian men were more likely to report as their reason for attendance that they wanted an HIV test (23.4% vs 14.8%, p=0.005). Conclusion: Despite having similar STI care needs to attendees from other ethnic groups, South Asians, especially women, may be reluctant to seek care from GUM clinics, especially if their symptoms resolve. Sexual health services need to develop locally-delivered and culturally-appropriate initiatives to improve care pathways

    Upper bounds at the weak scale are put on all λijkâ€Čλimnâ€Č\lambda'_{ijk}\lambda'_{imn} type products of R-parity violating supersymmetry that may affect K-Kbar and B-Bbar mixing. We constrain all possible products, including some not considered before, using next-to-leading order QCD corrections to the mixing amplitudes. Constraints are obtained for both real and imaginary parts of the couplings. We also discuss briefly some correlated decay channels which should be investigated in future experiments.Comment: 13 pages, 2 figures, uses revtex. Constraints updated, and new constraints adde

    The generation of magnetohydrodynamic (MHD) waves and their instabilities are studied in galactic gaseous rotating plasmas with the effects of the magnetic field, the self gravity, the diffusion-convection of cosmic rays as well as the gas and cosmic-ray pressures. The coupling of the Jeans, Alfv{\'e}n and magnetosonic waves, and the conditions of damping or instability are studied in three different cases, namely when the propagation direction is perpendicular, parallel and oblique to the static magnetic field, and are shown to be significantly modified by the effects of the Coriolis force due to the rotation of cosmic fluids and the cosmic-ray diffusion. The coupled modes can be damped or anti-damped depending on the wave number is above or below the Jeans critical wave number that is reduced by the effects of the Coriolis force and the cosmic-ray pressure. It is found that the deviation of the axis of rotation from the direction of the static magnetic field gives rise to the coupling between the Alfv{\'e}n wave and the classical Jeans mode which otherwise results into the modified slow and fast Alfv{\'e}n waves as well as the modified classical Jeans modes. Furthermore, due to the effects of the cosmic rays diffusion, there appears a new wave mode (may be called the fast Jeans mode) in the intermediate frequency regimes of the slow and fast Alfv{\'e}n waves, which seems to be dispersionless in the long-wavelength propagation and has a lower growth rate of instability in the high density regimes of galaxies. The dispersion properties and the instabilities of different kinds of MHD waves reported here can play pivotal roles in the formation of various galactic structures at different length scales.Comment: 11 pages, 5 figure

    Psidium guajava L. known as Guava is a medicinal plant belonging to the family Myrtaceae. Syzygium cumini Linn. known as Jamun is a tropical tree belonging to the family Myrtaceae. Recent evidence has demonstrated that combination therapy could provide greater therapeutic benefits to diseases such as AIDS, cancer, atherosclerosis and diabetes, all of which possess complex etiology and pathophysiology that make the treatment difficult with single drug target approach. The present study was to compare the invitro anti-inflammatory activity of two plants from Myrtaceae family as well as to investigate the anti-inflammatory activity of the combined extracts (1:1mixture) of those plants by estimating the inhibition of cyclooxygenase, 5-lipoxygenase, cellular nitrite levels, inducible nitric oxide synthase and myeloperoxidase using RAW 264.7 cells. Total ethanolic extracts of shade dried leaves were prepared and subjected to invitro anti-inflammatory study. The percentage inhibition of COX and 5 LOX by the combined extract, at 100 ”g/ml was 55.67 and 48.02 respectively. The reduction in the cellular nitrite level (393.195 ”g) and MPO level (0.00205U/ml) was comparable to that of standard. The results of the study showed that at 100 ”g/ml, the combined extract (1:1 mixture) of the plants exhibited prominent anti-inflammatory activity than either of the individual plants in all the methods studied. On comparison of the anti-inflammatory activity, Syzygium cumini is found to be more active than Psidium guajava. Hence the combination of the two plants can be used to formulate drugs for various inflammatory disorders in traditional and modern medicine

    A comparative study of evaluate dose related feto-maternal effects of syntocinon during labor

    Get PDF
    Background: In times, Active management of Third stage is a gold standard rule, to reduce third stage complications. In the same tradition, we conceived the idea of “Active management of Labor”, as a whole, to reduce all the problems, maternal and fetal, to a minimum possible level. With this motto, and aim in mind we devised the protocol of study I present forthwith. Methods: This study was done in Dhiraj Hospital in Obstetrics and Gynaecology department. The study duration was 1 year. It was a comparative study comprising of patients who came in labor room under unit 3 included in group 1 and under other units included in group 2 and 3. In this study, those patients were augmented who came to labor room. These patients were studied after screening inclusion and exclusion criteria & its outcome was assessed.Results: Augmentation-delivery interval in primigravida was 4.5 hours in group 1, in group 2 it was 3 hrs, where as in group 3 active phase delivery interval was 8.1 hours, Augmentation-delivery interval in multigravida was 3.5 hours in group 1, in group 2 it was 3 hrs, where as in group 3 active phase delivery interval was 6 hours. The incidence of spontaneous vaginal delivery was higher in group 1 than in group 2 and 3. There was very less or absent of maternal complications observed in group 1 than in other 2 groups. Incidence of NICU admissions was only 1 % in group 1, whereas in other groups it was higher. There was no neonatal mortality noted in either group.Conclusions: There is significant reduction in the duration of labor by augmenting labor with slow low regulated dose of syntocinon drip, thus reducing the maternal exhaustion and morbidity due to prolonged labor. There is significant reduction in the operative interference like LSCS, vacuum and forceps delivery, thus reducing maternal morbidity associated with operative interference and anesthesia. It also reduces the cost of medical services. The incidence of fetal distress and LSCS for the same does not increase in the augmentation group, indicating that syntocinon can be safely used for the augmentation. At this time, much attention in the field of obstetrics is focused on attempting to reduce the rate of cesarean section, not only to reduce maternal morbidity, but to lower the cost of medical care. Our finding is that syntocinon administration can significantly reduce the cesarean section rate
