Subjective Evidence-Based Ethnography (SEBE) is a family of methods developed for investigation in social science based on subjective audio-video recordings with a miniature video-camera usually worn at eye-level (eye-tracking techniques are included). Facing a lack of tools for SEBE risk assessment when applied to high risk professional environments (e.g. anesthetists, aircraft pilots, nuclear reactor pilots), a protocol (version 1.1) was successfully developed and tested in nuclear industry with N1=59 participants and presented in a previous article. However, further cases were needed to demonstrate the robustness of the risk assessment protocol in other contexts. Further applications were thus undertaken with N2=75 participants from Air Force army, Police, Medicine and Nuclear industry during work activities lasting from 10 minutes to several hours. SEBE equipment was worn and the original risk assessment protocol was applied and/or discussed between participants and researchers for improvement. The protocol was enriched (version 2.3): 37% items were added. This illustrated the context sensitiveness of this sort of risk assessment. Limits of this new series of tests are discussed.

Puntius sarana sarana (Hamilton, 1822) is a tropical freshwater fish belonging to the Puntius genus of the minnow family. This species is commonly called as Sarputi or Olive barb. The species has both ornamental and food value. The species is found abundantly in the north-eastern region and has high market value as compared to the Indian major carps. Thus, the species has the potentiality to be used as candidate species in aquaculture production for multiplying farmers’ income. Keeping the information in view, the present study was conducted to evaluate the possibilities of using the species in the polyculture system of Tripura for better income to the fish farmers. Based on the different combination of fish species, four experimental groups (T1, T2, T3) including control (C) was set up at the farmers’ pond of Tripura. Total ten farmers were selected from the Dhalai district of Tripura. The study revealed that the introduction of P. sarana in the culture system produces more biomass or yield as compared to the conventional system. However, T1 showed the maximum yield. Furthermore, the species have shown lower specific growth rate as compared to the Indian major carps as well as silver carp. On the other hand, the P. sarana were more successful in the present climatic condition of Tripura and had higher survival percentage as compared to the other fishes. Replacement of either Labeo rohita or Cirrhinus mrigala with the olive barb gives the better yield as compared to traditional practice. Economic analysis revealed that the maximum revenue could be earned by replacing any species with the olive barb. However, among the P. sarana based polyculture system, the maximum revenue was earned in T1 group.

The experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from October 2015 to March 2016 aiming to develop an IPM package based on effective insecticides and bio-pesticides against tomato fruit borer (Helicoverpa armigera, Lepidoptera: Noctuidae). Tomato variety BARI tomato-14 was used as planting material. The experiment consisted of six treatments as- T1: Mechanical control, T2: Voliam Flexi 300 SC @ 0.5 ml/l of water at 7 days interval + Pheromone trap at 10 m2 distance, T3: Voliam Flexi 300 SC @ 0.5 ml/l of water + Bioneem plus 1EC (Azadiractin) @1 ml/l of water at 7 days interval, T4:  Bioneem plus 1EC (Azadiractin) @1 ml/l of water + Spinosad 45 SC @ 4 ml/10l of water (bio-pesticides) + Pheromone trap at 10 m2 distance, T5: Mechanical control + Voliam Flexi 300 SC @ 0.5 ml/l of water + Bioneem plus 1EC (Azadiractin) @1 ml/l + Pheromone trap at 10 m2 distance and T6: Untreated control. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. At the total fruiting and ripening stage, the minimum number of fruit borer larvae per plant (0.73 and 1.00, respectively) was recorded from T5, while the maximum number of fruit borer larvae per plant (9.47 and 13.07, respectively) was found from T6. At entire ripening stage of tomato in number basis, the lowest percentage of infested fruits per plant in number basis (2.11%) was found in T5, while the highest percentage of infested fruits in number basis (11.55%) was found in T6 treatment. At entire ripening stage of tomato in weight basis, the lowest percentage of infested fruits per plant in weight basis (1.97%) was found in T5, while the highest percentage of infested fruits in weight basis (10.20%) was observed in T6. The highest fruit yield (59.82 t/ha) was found in T5, whereas the lowest fruit yield (50.36 t/ha) was recorded in T6 treatment. The highest benefit-cost ratio (2.11) was estimated for T5 treatment and the lowest (0.15) for T1 treatment under the trial. It is observed that Mechanical control + Voliam Flexi 300 SC @ 0.5 ml/l of water + Bioneem plus 1EC (Azadiractin) @1 ml/l + Pheromone trap at 10 m2 distance was more effective against the fruit borer of yield attributes and yield of tomato.

As fall out of transforming land use pattern coupled with the factors like resettlement, exposure to alien environment and effort to adjust with the new socio-agro-economic order, based upon their capability and resource endowment status, the tribal youth of North East Indian state of Tripura are in the look for various alternative occupations for their livelihood. In this backdrop, a study was conducted in two tribal dominated districts of the state, Dhalai and Gomati, to trace out the mechanism of interplay of various socio-personal factors over livelihood vis-a-vis occupational diversification of the tribal youth. Primary data were collected from 120 tribal youths following multistage sampling. Correlation and multivariate path analysis was undertaken for analysis of data. The delineation of decomposition of total effects against each of the perceived explaining variables into their respective direct, indirect and via effects as outcome of multivariate path analysis showed that land holding size, annual expenditure and economic motivation had the three highest order positive direct as well as indirect effect on the occupational diversity for resource poor category, whereas asset endowment, land holding size and economic motivation were of highest order for their resource endowed counterpart. Moreover, while annual income, achievement motivation and social inclusiveness revealed first three highest order negative direct as well as indirect effects on the occupational diversity for resource poor category, those were annual income, decision making ability and cosmopoliteness for the resource endowed category. Still further, a handful of variables was also found to have substantially interplayed in channelling their indirect effects through one or the other predictor variables. Occupational diversification appeared to be the consequence of a complex interplay of multiple factors. However, the appearance of substantial residual values as outcome of path analysis called for inclusion of more supplementary contextual explainers for any such future study.
