Unravelling the layers of Indian culture and worldview: an exploratory study

The purpose of this exploratory study is to explore worldview of budding Indian management professionals. Taking an interpretivist epistemological position, this paper attempt to address the ontological perspective of Indians. Respondents were asked to write their views on 'What is reality according to people around you? ' Followed by one 90-minute focus group discussion (FGD) and two in-depth interviews were conducted. Four types of analyses were conducted to minimise researcher bias and touch deeper layer of meaning. Based on Schein's layers of culture, the paper ends by proposing multiple layers in Indian culture namely, basic assumptions, values and artefacts. Paper conjecture 'go with the flow' or samarpan (devotion) as the deep-rooted philosophy or basic assumption that influences Indian values and practices. Typical Indian values: faith in God, paradoxical mindset, family orientation, contextual sensitivity, and tolerance. The physical artefacts: jugaad, adaptability, visit to temples, prayers, fasting, yoga, meditation and tolerance for ambiguity.
Effect of Pebble Size Distribution and Wall Effect on Inner Packing Structure and Contact Force Distribution in Tritium Breeder Pebble Bed

In the tritium breeding blanket of nuclear fusion reactors, the heat transfer behavior and thermal-mechanical response of the tritium breeder pebble bed are affected by the inner packing structure, which is crucial for the design and optimization of a reliable pebble bed in tritium breeding blanket. Thus, the effect of pebble size distribution and fixed wall effect on packing structure and contact force in the poly-disperse pebble bed were investigated by numerical simulation. The results show that pebble size distribution has a significant influence on the inner packing structure of pebble bed. With the increase of the dispersion of pebble size, the average porosity and the average coordination number of the poly-disperse pebble bed gradually decrease. Due to the influence of the fixed wall, the porosity distribution of the pebble bed shows an obvious wall effect. For poly-disperse pebble bed, the influenced region of the wall effect gradually decreases with the increase of the dispersion of pebble size. In addition, the gravity effect and the pebble size distribution have an obvious influence on the contact force distribution inside the poly-disperse pebble bed. The majority of the contact force are weak contact force that is less than the average contact force. Only a few of pebbles have strong contact force that is greater than average contact force. This investigation can help in analyzing the pebble crushing characteristics and the thermal hydraulic analysis in the poly-disperse tritium breeder pebble bed.
The Link Between Demography and Labour Markets in sub-Saharan Africa

This rapid review synthesises the literature from academic, policy, and knowledge institution sources on how demography affects labour markets (e.g. entrants, including youth and women) and labour market outcomes (e.g. capital-per-worker, life-cycle labour supply, human capital investments) in the context of sub-Saharan Africa. One of the key findings is that the fast-growing population in sub-Saharan Africa is likely to affect the ability to get productive jobs and in turn economic growth. This normally happens when workers move from traditional (low productivity agriculture and household businesses) sectors into higher productivity sectors in manufacturing and services. In theory the literature shows that lower dependency ratios (share of the non-working age population) should increase output per capita if labour force participation rates among the working age population remain unchanged. If output per worker stays constant, then a decline in dependency ratio would lead to a rise in income per capita. Macro simulation models for sub-Saharan Africa estimate that capital per worker will remain low due to consistently low savings for at least the next decades, even in the low fertility scenario. Sub-Saharan African countries seem too poor for a quick rise in savings. As such, it is unlikely that a lower dependency ratio will initiate a dramatic increase in labour productivity. The literature notes the gender implications on labour markets. Most women combine unpaid care for children with informal and low productive work in agriculture or family enterprises. Large family sizes reduce their productive labour years significantly, estimated at a reduction of 1.9 years of productive participation per woman for each child, that complicates their move into more productive work (if available). If the transition from high fertility to low fertility is permanent and can be established in a relatively short-term period, there are long-run effects on female labour participation, and the gains in income per capita will be permanent. As such from the literature it is clear that the effect of higher female wages on female labour participation works to a large extent through reductions in fertility.
The effect of ultrasound application and addition of leaves in the malaxation of olive oil extraction on the olive oil yield, oxidative stability and organoleptic quality

Abstract This research examines the effect of adding olive leaf on the yield and quality of the olive oil extracted from malaxation and ultrasound application during the olive oil extraction process. The olive variety Ayvalik was used in the trials, which included leaf addition of 2% and 5% and ultrasound application of 5, 10, 15, 20, 25, 30, 35, and 40 minutes (min). Several values, such as maturity index and oil yield, as well as olive oil parameters, including free acidity, peroxide value, oxidative stability, and specific ultraviolet absorption, were analyzed and examined. We also carried out sensory analyses on the extracted olive oils. The results show that the product extracted has no sensory defects and exhibits a fruitiness level greater than 0. The research showed that, in terms of yield and quality, a time span of 15 min with addition of 2% olive leaf would provide optimum conditions in ultrasound assisted olive oil extraction with olive leaf addition. The olive oils produced in this process fall into the category of “extra virgin olive oil”.
Mantle sources of Cenozoic volcanic activities around the South China Sea revealed by geochemical and isotopic data using the principal component analysis (PCA)

Principal component analysis (PCA) was conducted to analyze geochemical and isotopic data and interpret the characteristics and types of mantle sources of Cenozoic volcanic activities around the South China Sea (SCS). Fifteen trace element indicators and five isotopic indicators were surveyed from 623 volcanic rock samples obtained from the SCS, Hainan Island, Fujian–Zhejiang, Taiwan, Vietnam, and Thailand to characterize the geochemical properties of the volcanic rocks, determine the types of mantle sources, and assess the influence degree of each mantle source. Two principal components (PCs) were extracted by PCA based on trace elements and Sr–Nd–Pb isotopic ratios, which are an enriched oceanic island basalt-type mantle plume and a depleted mid-ocean ridge basalt-type spreading ridge. In the Southeast Asian region, the influence of Hainan mantle plume on younger volcanic activities (< 13 Ma) was greater than that on older ones (> 13 Ma) in the same location. PCA was used to verify the mantle plume–ridge interaction model of volcanic activities beneath the expansion center of the SCS and refute the hypothesis that the tension in the SCS is triggered by the Hainan plume. The results of this study demonstrate the efficiency and applicability of PCA to the discussion of mantle sources of volcanic activities and provide a new method with which to analyze geochemical data.

Fuzzy Lyapunov-Based Model Predictive Sliding-Mode Control of Nonlinear Systems: An Ellipsoid Recursive Feasibility Approach

In this article, we introduce the design of an artificial fuzzy Lyapunov-based model predictive integral sliding-mode control to achieve the stability of the closed-loop Takagi–Sugeno fuzzy-model-based nonlinear systems. First, to reach the proper performance against the model uncertainties, a fuzzy integral sliding-mode controller (FISMC) is designed. Then, the fuzzy model predictive control (MPC) is developed based on a fuzzy Lyapunov function by considering a contractive constraint and an ellipsoidal terminal constraint. A systematic method is developed to reach the recursive feasibility of the MPC optimization problem based on an ellipsoidal terminal set. Also, a contractive fuzzy Lyapunov condition is imposed on the fuzzy MPC problem to guarantee the stability of closed-loop systems, which is led to a linear matrix inequality-based generalized eigenvalue minimization problem. In the proposed approach, FISMC greatly improves the robustness property of the fuzzy Lyapunov-based model predictive control and the asymptotic stability of the closed-loop system is achieved in comparison with the tube-based MPC. In addition, the proposed robust MPC has a less computational burden and improves the equilibrium point attractivity compared with the max–min MPC and the equality terminal constraint-based MPC. To illustrate the superiority of the proposed strategy, the suggested robust MPC is applied to a truck–trailer system and a numerical example. The simulation results show the capabilities of the proposed robust MPC.
Automatic Emotion Recognition for Groups: A Review

This article aims to summarize and describe research on the topic of automatic group emotion recognition. In recent years, the topic of emotion analysis of groups or crowds has gained interest, with studies performing emotion detection in different contexts, using different datasets and modalities (such as images, video, audio, social media messages), and taking different approaches. Articles are included after an innovative search method, including Dense Query Extraction and automatic cross-referencing. Discussed are the types of groups and emotion models considered in automatic emotion recognition research, common datasets for all modalities, general approaches taken, and reported performances. These performances are discussed, followed by an analysis of the application possibilities of the discussed methods. To ensure clear, replicable, and comparable studies, we suggest research should test on multiple, common datasets and report on multiple metrics, when possible. Implementation details and code should be made available where possible. An area of interest for future work is to build systems with more real-world application possibilities, coping with changing group sizes, different emotional subgroups, and changing emotions over time, while having a higher robustness and working with datasets with reduced biases.
Commercial Spirits for Surfactant-Free Syntheses of Electro-Active Platinum Nanoparticles

The Co4CatTM process is a simple, surfactant-free method to produce colloidal dispersions of precious metal nanoparticles in alkaline mono-alcohols. The synthesis is performed in low-boiling-point solvents and is relevant for industrial production. The robustness of the process is demonstrated by using three different commercial spirits as solvents to obtain Pt nanoparticles. The results demonstrate that careful control of the solvent purity is not needed to achieve the synthesis of stable 2 nm platinum nanoparticle colloids readily active electrocatalysts for energy conversion reactions like the methanol oxidation.
Effect of single-dose dexmedetomidine on the incidence of emergence delirium after sevoflurane-based anesthesia in children undergoing strabismus surgery

ABSTRACT Backgroun: Though Emergence Delirium (ED) in children is a short duration, often self-limited, episodes, its prevention is essential. This study aims to evaluate the effect of single-dose dexmedetomidine on the incidence of ED in pediatrics who underwent strabismus surgery under sevoflurane-based anesthesia. Methods: The study consisted of 70 ASA I–II children who were 3–7 years old and scheduled for strabismus correction surgeries under sevoflurane anesthesia. The clinical trial registry is PACTR201911530033705, registered on the 3rd of November, 2019. Patients were randomly allocated into two groups (dexmedetomidine and control groups). Patients were administered either dexmedetomidine (0.3 µg/kg intravenous in 10 ml normal saline) or 10 ml normal saline, ten minutes before the end of the procedure (before discontinuation of sevoflurane). Our primary aim was to measure the incidence of ED. Watcha and PAED scores were measured simultaneously with FLACC score on arrival to PACU every ten minutes until 30 minutes, then at discharge. Besides, recovery time from anesthesia, length of PACU stay, parent’s satisfaction, and adverse effects were also recorded. Results: The incidence of ED was 17.6% and 57.6% in groups D and C, respectively. The Watcha and PAED scores were significantly higher in group C during PACU stay while FLACC score was significantly higher in group C on PACU arrival. Despite the significant delay of anesthetic recovery (p < 0.001), PACU stay was significantly shortened (p < 0.001) in group D. Parent’s satisfaction score was significantly better in group D (p = 0.002) without significant differences between both groups regarding adverse effects. Conclusions: This study demonstrates that a single dose of dexmedetomidine is effective in prophylaxis against ED in children after sevoflurane-based anesthesia. Despite its association with delayed recovery, dexmedetomidine shortened PACU stay and could be used safely in children.
Clinical outcomes and structural integrity rate of arthroscopic augmented rotator cuff repairs using extracellular porcine matrix patch

Background Structural failure rate in rotator cuff repairs is still high. The purpose of the study is to assess the structural integrity of a series of augmented rotator cuff repairs with porcine matrix patch and report the functional outcomes. Methods Between 2014 and 2017, 44 consecutive patients underwent arthroscopic double-row repair of medium to massive rotator cuff tears with extracellular porcine dermal matrix augmentation. At one-year follow-up, magnetic resonance imaging scan was performed to assess the integrity of the repair. Oxford Shoulder Score (OSS), Constant Score (CS) and Visual Analogue Scale pain score, together with range of motion were used to assess patients. Results Patients mean age was 68 (53–82); mean follow-up was 17.2 (12–24) months. On magnetic resonance imaging scans, seven rotator cuff repair failures (15.9%) were observed: tear size was an independent predictor of re-rupture at one-year follow-up. Clinical scores showed a statistically significant improvement at three months and until final follow-up (p< 0.001). No complications occurred. Conclusion Observed structural failure rate of 15.9% is lower than those reported in the literature for standard rotator cuff repair of medium to massive tears in similar cohorts to ours. Extracellular matrix augmentation for rotator cuff repair was shown to be a safe and reliable support to the repairs and patients recovered good shoulder function. Level of Evidence: Level IV.

The Impacts of Threat Emotions and Price on Indonesians' Smartphone Purchasing Decisions

This research aims to determine the effect of customers’ threat emotion and price on the decision to purchase a certain smartphone product. This study uses a quantitative method with a type of descriptive and causal research. It employs non-probability sampling with purposive sampling, with 385 respondents to answer the questionnaires. Data analysis techniques used descriptive analysis and multiple linear regression analysis. Based on the results of descriptive analysis of emotion, price and purchasing decisions are in sync with each other. The results of multiple linear regression analysis techniques indicate the threat emotion and brand trust are influential against the positive decision to purchase smartphone products. The magnitude of the influence of emotions and price have simultaneous effect on purchasing decisions and other decision variables, which are not included in this study, also play minor role in determining purchase intention, such as product quality, brand image and others. Partially, threat emotion and brand trust have a positive effect toward purchasing decisions. The magnitude of the highest influence was the one of price, then followed by emotional threats. The findings of this study suggest that psychological and behavioral effects also play important roles in determining customers’ purchase decision.
Performance enhancement of the piezoelectric ceramics by alternating current polarizing

The piezoelectric properties of the PZT-5H ceramics under various polarization conditions are compared and analyzed. It is worth noting that compared to direct current polarization, the piezoelectric coefficient (d33), free dielectric constant ( e 33 T/ e 0), and electromechanical coupling coefficient (kt) of the PZT-5H ceramics under alternating current polarization (ACP) have increased by 10.7%, 15.9%, and 15.4%, respectively. According to the analysis of the domain distribution patterns in the [001] surface of the PZT-5H ceramics under the two polarization conditions measured using a piezoresponse force microscope, the ACP makes the piezoelectric material have a high density of the domain wall, which greatly enhances its piezoelectric performance. This work provides an effective means to improve the piezoelectric properties of PZT-5H ceramics and will be of great significance to piezoelectric applications using this type of piezoelectric ceramic.
Distributed Dual Optimization for the Uplink of Multi-Cell NOMA

This paper studies distributed power control for the uplink of multi-cell non-orthogonal multiple access (NOMA) systems. Within a cell, the transmissions of different users are modeled as a Gaussian multiple access channel, treating inter-cell interference as additive Gaussian noise. By analyzing the geometry of the feasible power region, using successive interference cancellation at each base station is proved to be optimal in minimizing the total transmission power of all users under rate constraints. The decoding order at each base station, however, remains to be determined. If the decoding order is decided without base station cooperation, the overall control algorithm is fully distributed but is suboptimal in general. To achieve optimality, a partially distributed algorithm is designed, which requires base stations to exchange control messages. Given any feasible instance, the algorithm is proved to converge to the optimal solution. The performance of the fully distributed and partially distributed power control algorithms is compared by computer simulations. The fully distributed algorithm is nearly optimal in terms of outage probability. When a high data rate is required, the partially distributed algorithm is able to reduce the total power consumption by about 20%.

The present cross sectional study aimed to understand the parents’ perspective on imparting reproductive health education to adolescents in schools. 60 parents of school going adolescent children were interviewed with the help of an interview guide. Findings of the study revealed that the parents favored the idea of imparting reproductive health education to adolescents in schools by the teachers. The study highlighted the requirement of specialized knowledge and module for imparting reproductive health education in conjunction with the social norms of society.
RESULT OF MINIMALLY INVASIVE PLATE OSTEOSYNTHESIS (MIPO) WITH USE OF LOCKING PLATE IN FRACTURE TIBIA DISTAL END

Background: The fractures of distal tibia including tibial pilon pose a great challenge to the surgeon due to subcutaneous location, scarcity of blood supply and paucity of soft tissue coverage. Minimal invasive plating osteosynthesis (MIPO) has evolved as a newer concept to treat distal tibial fractures with minimal articular comminution and minimal soft tissue damage. Aim of the present study was to evaluate the results of MIPO technique with use of a locking plate in fracture tibia distal end. Method: During the study period of two years, total 45 cases of closed distal tibial fractures (Diaphyseal and metaphyseal region) were operated by MIPO technique with a distal tibial anatomical locking plate (3.5 and 4.5 mm). They were followed up at regular intervals and results were evaluated. Results: The age of the patients ranged from 20-60 years with the majority (19; 42.22%) of them being in the age of 40-50 years. The most common mode of injury was road traffic accident (33; 73.33%). In all patients MIPO was performed, in none of them, fracture site was opened. Mobilization of adjacent joints was carried out mostly from second to fourth postoperative day. Most of the fractures united between 10-12 weeks (26; 57.77%). On analyzing the results of MIPO, excellent results were seen in 66.66% cases and 33.34% had satisfactory results. Conclusion: Hereby we concluded that though various modalities of treatment of fractures of the distal tibia are present MIPO seem to be better technique if done under skillful guidance as done in this study.
