Medical education in India is undergoing a landmark transformation under the National Medical Commission implementing competency-based medical education (CBME). The CBME approach intends to ensure that medical graduates acquire the competencies needed to fulfill the health needs of the patient and society. This outcome-based approach shifts the focus from the traditional knowledge-based training to skill-based training valued on attitude, ethics, and communication (AETCOM) competencies. CBME thus aims to create medical professionals capable of providing holistic care with compassion and excellence embracing the global trends. The opportunity posed by the CBME should be utilized to sensitize and create interest among the learners about the science and scope of psychiatry. However, there are many challenges in the successful implementation of CBME, which have to be identified and addressed on time for serving the purpose. A basic tenet in CBME is to continue training until the desired competencies are achieved; in other words, to de-emphasize time-based learning. Moreover, the current COVID 19 pandemic is posing a significant influence on the execution of CBME implemented in August 2019. Online platforms could have several advantages in assisting the implementation of CBME; they provide an alternative to continue teaching-learning and assessment during these times and allow learners with the flexibility to learn at their own pace. In this article, we discuss the opportunities, including digital platforms and challenges to be overcame as well as the need for training the faculty toward assimilating the curriculum in the undergraduate psychiatric training.

The origin of various defect levels in the SnS thin films deposited using chemical spray pyrolysis (CSP) technique has been explored in this manuscript, by employing low-temperature photoluminescence (PL) technique. Concentration of Sn in the samples was varied purposefully by ex situ diffusion in order to alter the defect levels. The acceptor level obtained at 0.22 eV from the Arrhenius plot, has been assigned as the defect level caused by the Sn vacancies present in the lattice. Two shallow donor levels are conclusively identified and their activation energies have been estimated. The present study could also unearth a trap level in the forbidden energy gap which was due to the oxygen contaminant occupied by the vacancy of Sn. This trap level could be removed by annealing the sample in vacuum or through the ex situ diffusion of Sn. Employing Kelvin probe force microscopy (KPFM), the work-function of SnS was obtained as 4.925 eV, from which the position of the Fermi level could be assigned. Based on the present work, an energy level scheme for SnS thin films is proposed outlying origin of various defect levels.

The levels of resistance to spotted stem borer (Chilo partellus) in sorghum are low to moderate. We therefore evaluated wild relatives of sorghum to identify accessions with high levels of resistance to this pest and studied the mechanisms of resistance. Heterosorghum (Sorghum laxiflorum), Para-sorghum (S. australiense, S. purpureo-sericeum, S. versicolor, S. matarankense, S. timorense, S. brevicallosum and S. nitidum) and Stiposorghum (S. angustum, S. ecarinatum, S. extans, S. intrans, S. interjectum and S. stipoideum) showed very high levels of resistance to stem borer. Chaetosorghum (S. macrospermum), four wild races of S. bicolor subsp. verticilliflorum and S. halepense were found to be susceptible. Under no-choice conditions, egg laying was observed on all accessions, which significantly differed among the species/accessions. Accessions belonging to Stiposorghum and Para-sorghum (S. purpureo-sericeum, S. versicolor and S. timorense) were significantly less preferred for oviposition than the resistant control, IS 2205. Accessions belonging to Stiposorghum showed slight leaf-feeding, but there was no deadheart formation. Although there was some damage in Para-sorghum, very few deadhearts were formed, and a few larvae that were recovered subsequently died. In Heterosorghum, the two accessions of S. laxiflorum were highly preferred for oviposition, and up to 82% deadhearts were recorded, but the six larvae that were recovered died within a month. Accessions belonging to Eu-sorghum showed maximum deadhearts, larval recovery and adult emergence. The results suggested that some of the wild relatives of sorghum possess high levels of resistance to C. partellus and both antixenosis and antibiosis are major components of resistance to this pest. Accessions showing high levels of resistance to stem borer can be utilized to increase the levels and diversify the bases of resistance to this pest in sorghum.

The levels of resistance to shoot fly, Atherigona soccata in sorghum germplasm are low to moderate and therefore, we evaluated 17 wild relatives of sorghum under field and greenhouse conditions as an alternate source of genes for resistance to this pest. Thirty-two accessions belonging to Parasorghum, Stiposorghum and Heterosorghum did not suffer any shoot fly damage under multi-choice conditions in the field, while one accession each of Heterosorghum (Sorghum laxiflorum) and Chaetosorghum (S. macrospermum) suffered very low shoot fly damage. Accessions belonging to S. exstans (TRC 243601), S. stipoideum (TRC 243399) and S. matarankense (TRC 243576) showed absolute non-preference for oviposition under no-choice conditions. Accessions belonging to Heterosorghum, Parasorghum and Stiposorghum were preferred for oviposition, but suffered low deadheart formation. Manual infestation of seedlings with shoot fly eggs did not result in deadheart formation in some of the accessions belonging to S. exstans (TRC 243601), S. stipoideum (TRC 243399), S. matarankense (TRC 243576) and S. purpureosericeum (IS 18944). Larval mortality was recorded in main stems of the Parasorghums. Within section Sorghum, accessions belonging to S. bicolor ssp. verticilliflorum were highly susceptible to shoot fly, as were those of S. halepense. However, a few accessions such as IS 18226 (race arundinaceum) and IS 14212 (S. halepense) resulted in reduced survival and fecundity. Wild relatives of sorghum exhibited very high levels of antibiosis to A. soccata, while only low levels of antibiosis have been observed in the cultivated germplasm. Therefore, wild relatives with different mechanisms of resistance can be used as a source of alternate genes to increase the levels and diversify the basis of resistance to shoot fly, A. soccata.

Variations in the trypsin inhibitors and lectin content in the developing pods of thirty accessions of Cajanus scarabaeoides, a wild relative of pigeonpea, from wide geographical locations and six cultivated genotypes were estimated at juvenile, immature and mature stages of pod development. Genotypes differed at all three stages for these two biochemical components. Total protein and trypsin inhibitor contents were higher in the wild accessions than in the cultivated genotypes. Although lectin content in the juvenile stage of pod development in the wild accessions ICPW 138 and ICPW 98 was highest, it was absent in the mature pods in both the cultivated and the wild genotypes. Very high broad-sense heritability estimates indicated the possibility of involvement of few genes in the inheritance of these biochemical components, which could be easily introgressed into the elite agronomic background.

Sorghum downy mildew (SDM), caused by Peronosclerospora sorghi Weston and Uppal (Shaw), is a serious disease of sorghum [Sorghum bicolor (L.) Moench] and maize (Zea mays L.). The wild relatives of sorghum, both cross compatible and cross incompatible with S. bicolor, could provide alternate sources of resistance genes for the long-term control of SDM. The objective of this study was to assess the downy mildew reaction of several taxa of wild and weedy sorghums. One hundred three wild and weedy sorghums, and six cultivated types belonging to five sections, representing 17 species, originating from Asia, Australia, Africa, and the USA, were greenhouse tested for downy mildew resistance during the rainy seasons of 1998 and 1999 at ICRISAT, Patancheru, India. Forty-five accessions comprising 15 species from four sections, parasorghum, heterosorghum (S. laxiflorum Bailey), chaetosorghum (S. macrospermum Garber), and stiposorghum (S. angustum S. T. Blake, S. ecarinatum Lazarides, S. extans Lazarides, S. intrans F. Muell. ex Benth., S. interjectum Lazarides, S. stipoideum (Ewart & Jean White) C. Gardener & C. E. Hubb.), including all accessions from Australia, exhibited immunity to downy mildew. Cultivated types and wild races of section Sorghum showed the greatest susceptibility (mean downy mildew infection of 62 and 46%, respectively), while accessions of S. halepense (L.) Pers. were comparatively less susceptible (36% mean downy mildew infection). Potential new sources of resistance genes from wild and weedy sorghums were identified that could be used to develop resistant cultivars to control downy mildew.

The paper deals with the estimation of comparable human rights ratings (defined as a composite of political rights, civil liberties and state power indices) for 154 countries, excluding territories, of the world in 1983. It then develops a theory to gauge the sensitivity of these ratings to a specific disaggregation suggested by the theory of political economy and establishes the close nexus existing between economic systems, political structures and human rights. The results indicate that increasing government intervention, whether economic or political, unequivocally tends to worsen the human rights situation. Moreover, it is seen that affluence and income distribution are significant predictors of human rights ratings across countries.
