Although research on entrepreneurial attitude and intention has received so much attention from scholars, only few studies have investigated the effect of value, usefulness, and pleasure associated with business simulation games, and how these values affect students' attitude and intention toward entrepreneurial activities. In this study, Technology Acceptance Model and Theory of Planned Behavior have been used in combination to explore how these technological teaching methods influence the attitude and intentions of the students toward entrepreneurial activities. The results show that all hypotheses have been proven by stating significant and positive students' attitude and intention toward entrepreneurial activities using business simulation games. But subjective norms did not contribute toward student intentions in this regard. It is concluded that people with high uncertainty avoidance are reluctant to take the risk; therefore, there is a need to change their attitude by implementing entrepreneurial ecosystem in society.

In the Loess Plateau region of China, winter wheat often undergoes prolonged cloudy days without rain which may affect the grain yield and quality. This study examined the impacts of shading and drought conditions during the grain‐filling period of winter wheat (Triticum aestivum L.) on photosynthesis, grain yield and quality traits in a greenhouse experiment. The imposed shading and irrigation‐deficit treatments were corresponded with naturally cloudy weather in the rainfed area. Five shading treatments, 15 days shading (SD15); 12 days shading (SD12); 9 days shading (SD9); 6 days shading (SD6); and 3 days shading (SD3), and four irrigation treatments: full irrigation (I100); 75% of full irrigation (I75); 50% of full irrigation (I50); and 25% of full irrigation (I25), were applied after completion of flowering. The results showed that shading during grain filling decreased the grain yield and individual grain weight irrespective of the dry or wet conditions of the soil. Plant height increased with a decrease in shading duration to favour the efficient capturing of light. The reduction in the rate of photosynthesis was noted with an increase in the drought intensity. Shading significantly reduced the grain protein contents and increased the grain starch contents. In conclusion, shading for a long duration (SD15, SD12 and SD9) and drought stress (I25) during the grain‐filling stage significantly decreased the yield and grain quality of winter wheat. The shading of few days without drought (I100: SD3, SD6 and SD9) improved the plant height, photosynthetic activity and increased the distribution of dry matter from vegetative organs to grains.

Near-infrared spectroscopy (NIR) is a non-destructive, fast, and low-cost method to measure the grain quality of different cereals. However, the feasibility for determining the critical biochemicals, related to the classifications for food, feed, and fuel products are not adequately investigated. Fourier-transform (FT) NIR was applied in this study to determine the eight biochemicals in four types of sorghum samples: hulled grain flours, hull-less grain flours, whole grains, and grain flours. A total of 20 hybrids of sorghum grains were selected from the two locations in China. Followed by FT-NIR spectral and wet-chemically measured biochemical data, partial least squares regression (PLSR) was used to construct the prediction models. The results showed that sorghum grain morphology and sample format affected the prediction of biochemicals. Using NIR data of grain flours generally improved the prediction compared with the use of NIR data of whole grains. In addition, using the spectra of whole grains enabled comparable predictions, which are recommended when a non-destructive and rapid analysis is required. Compared with the hulled grain flours, hull-less grain flours allowed for improved predictions for tannin, cellulose, and hemicellulose using NIR data. This study aimed to provide a reference for the evaluation of sorghum grain biochemicals for food, feed, and fuel without destruction and complex chemical analysis. [ABSTRACT FROM AUTHOR]

Though the Chinese government has projected the BRI in economic terms, it has been viewed critically by Australia, Japan, and the U.S. Turkey has, as a geostrategic connector of Asia and Europe, registered its trade interest in the BRI along with projecting the Middle Corridor Initiative (MCI) as a means to realize regional market connectivity and commercial cooperation. In view of the aforesaid, this study aims to explain whether the BRI has factored into Turkey's Asia policy and to what extent the MCI can complement the BRI. Moreover, the study analyzed the existing scale of China-Turkey trade and proposed a set of opportunities offered by both the BRI and the MCI. Nonetheless, the stated opportunities are beset with multiple challenges ranging from transregional instability to socio-economic upheavals. In order to accrue trade dividends in terms of inter-initiative cooperation and connectivity, both China and Turkey will have to play a leading role in developing policy coordination and establishing cultural linkages among the BRI/MCI community. Thus, operationally, Turkey would carry immense influence in Asian affairs economically and strategically. [ABSTRACT FROM AUTHOR]

Belt and Road Initiative is China's global infrastructure program. This long-term investment strategy is aimed at improving regional cooperation, increased trade and economic integration by linking Asia with Europe and Africa through maritime and land networks. South Asia is vital for Belt and Road Initiative of China. China views South Asia as a priority zone because its geostrategic location will contribute a lot in the preferment of the BRI. This research intends to highlight the geo-strategic and geo-economic implications of BRI on security and economy of South Asian states. This study is carried out using qualitative research methodology. Data was collected through primary and secondary sources including books, journals, research papers, articles and videos of seminars and conferences on the concerned topic and interviews of experts of BRI and CPEC were also conducted. According to the research, BRI is the manifestation of Mackinder's heartland theory. BRI fortifies intra-state transport connectivity, improves international connectivity, will help to ease power shortages and facilitate economic modernization and industrialization in South Asia. The findings of this research show that China is expanding its diplomatic influence through its economic presence in South Asia causing serious challenges to India's power in the region and USA's status of global hegemon. Along with the opportunities of BRI, there are a number of risks of political instability, poor law and order situation, corruption, terrorism and extremism in South Asia, hindering the smooth functioning of BRI projects. Also there is a fear of Chinese debt trap and loss of sovereignty in South Asian states making them reluctant to fully permit the execution of Chinese led projects on their land.

The contemporary study was designed to investigate farmer's participation behavior concerning public sector agricultural extension services, by comparing the situations of two countries, Pakistan and China. The logistic regression model was used to study the influence of age, education, labor, farm area and villages on the household head's participation in agricultural extension services/activities organized by public sector department. For this purpose, a random sample of 160 households from four districts of Punjab province of Pakistan was selected, and another random sample of 122 households selected from the six villages of Huailai County of Hebei Province in China. Data were collected using the interview method with the help of validated and expert reviewed interview schedule. The results revealed that the household head's average age is 47 years in Pakistan and 53 years in China. The old aged household head's participation in extension services in Pakistan is less (36%) than China (43%). Similarly, household head's education is 9 years schooling in Pakistan accounting less participation (25%) in agricultural extension services while 7 years schooling in China with higher participation (57%) in agricultural extension services. Governments of the Pakistan and China should launch massive adult literacy programs to increase the educational level of the farming community together with the involvement of youth in agricultural farming and agro-based enterprises to achieve sustainable rural livelihood and improved living standards.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new pandemic infectious disease that originated in China. COVID-19 is a global public health emergency of international concern. COVID-19 causes mild to severe illness with high morbidity and mortality, especially in preexisting risk groups. Therapeutic options are now limited to COVID-19. The hallmark of COVID-19 pathogenesis is the cytokine storm with elevated levels of interleukin-6 (IL-6), IL-1β, tumor necrosis factor-alpha (TNF-α), chemokine (C-C-motif) ligand 2 (CCL2), and granulocyte-macrophage colony-stimulating factor (GM-CSF). COVID-19 can cause severe pneumonia, and neurological disorders, including stroke, the damage to the neurovascular unit, blood-brain barrier disruption, high intracranial proinflammatory cytokines, and endothelial cell damage in the brain. Mast cells are innate immune cells and also implicated in adaptive immune response, systemic inflammatory diseases, neuroinflammatory diseases, traumatic brain injury and stroke, and stress disorders. SARS-CoV-2 can activate monocytes/macrophages, dendritic cells, T cells, mast cells, neutrophils, and induce cytokine storm in the lung. COVID-19 can activate mast cells, neurons, glial cells, and endothelial cells. SARS-CoV-2 infection can cause psychological stress and neuroinflammation. In conclusion, COVID-19 can induce mast cell activation, psychological stress, cytokine storm, and neuroinflammation. [ABSTRACT FROM AUTHOR]

The forecast of CO2 emissions is very crucial, especially for Pakistan as it is one of the top victims of climate change. A univariate model, (ARIMA) autoregressive integrated moving average (ARIMA), was used to forecast CO2 emissions for Pakistan. The CO2 emissions scenarios were developed for Pakistan till 2020, forecasting them further to 2030. The scenarios developed include China–Pakistan Economic Corridor (CPEC) scenario, where CO2 emissions from high‐priority energy projects under the CPEC were considered. The scenarios attempt to estimate the impactful emission reduction percentage, which the country needs to adopt along with other necessary changes in the existing policies of the country. The forecast results clearly indicate that the emissions are bound to increase under business as usual and CPEC scenarios and the country would fail to meet the Nationally Determined Contributions pledged at COP21. In other scenarios, where we assumed the country has adopted mitigatory strategies to curb the emissions, the forecast shows decreased CO2 emissions for Pakistan. The mean absolute percentage error for all the forecasts was found to be less than 10%, making the forecast highly accurate. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.

This work investigates the dynamic heterogeneous causal links among financial development, construction industry, energy use, and environmental quality across the development levels, for 30 Chinese provinces during the period 2001–2016. For this purpose, a model of environmental quality has been constructed introducing the financial development and construction industry as endogenous factors. A Pedroni's cointegration is employed and found the long-run cointegrating mechanism among the variables of interest. The dynamic common correlated effects mean group approach (DCCEMGA) is adopted to estimate the impact elasticities. Moreover, for robustness check, a sensitivity analysis is conducted employing common correlated effects mean group approach (CCEMGA). The main results are first, a two-way positive causal bridge is existent between gross domestic product (GDP) and energy use, construction industry and GDP, and financial development and GDP. In terms of the contribution of the construction industry to economic performance, construction industry-driven growth acceleration impact is observed. Second, a one-way positive causal link is identified running from financial development (both the banking sector and stock market) to the construction industry and is termed as finance-driven construction promotion effect. Also, a one-sided positive causal connection is operating from financial development and construction industry to energy use and carbon dioxide emissions. Finally, a standard environmental Kuznets curve (EKC), financial development-augmented EKC, and construction industry-augmented EKC hypotheses are found valid in the whole country and eastern region of China. Based on empirics, a regional heterogeneity has been observed in terms of the degree of impact and statistical significance while comparing the regional panels. The sensitivity analysis proved the empirical results to be robust and reliable. Moreover, based on the findings, policy recommendations are documented. [ABSTRACT FROM AUTHOR]

Citrus leafminer (CLM), Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) is among the serious insect pests attacking citrus plants in Pakistan. The study was conducted to quantify the leaf area damage of eight citrus cultivars caused by mining activity of CLM during summer 2016. The total leaf area and mine area per leaf were calculated by the image analysis method using Sigma Scan Pro 5.0 software. The results of the present study showed that CLM generated larger mines; 1.64 cm2 on Grapefruit, 1.44 cm2 on Kinnow and 1.40 cm2 on Succari compared to other five cultivars. However, the percent leaf damage due to the feeding of CLM larvae was observed higher 44.2% on Fairchild, 36.5% on seedless Kinnow, 36.3% on Feutrell's early and 35.8% on Kinnow that showed great susceptibility to CLM. Smallest mines generated by CLM larvae were found on China Lemon and Succari showing the lowest damage percentage compared to other cultivars. Conclusively, the C. tangerines and C. mandarins were the most preferred cultivars by CLM larvae for feeding on the leaf surface. The image analysis method was accurate, relatively simple, easy and inexpensive to calculate the leaf area damage caused by CLM larvae. [ABSTRACT FROM AUTHOR]

The establishment of the Sultanare rule in Bengal marked the beginning of a standard monetized economy as well as emergence of new urban centres. These two most decisive factors transformed not only the economic life of the region but brought about a new era of political economy. Sustained minting of high-quality silver coinage and regular supply of war-horses for maintaining a strong cavalry formed two fundamental tasks for the Sultanate regime particularly in view of the fact that both the items i.e. raw silver and horses were not indigenous and the rulers were wholly depended on import. The primary goal of the paper is to reflect on the silver inflow and outflow into and from Bengal region through 13th to 16th centuries and correlate this with the expenditure faced by the Bengal Sultans on the maintenance of cavalry.

The article presents an analysis of the comparative advantage of the footwear industry in Pakistan when compared with China and India, using the Balassa Index at 2-digit and 4-digit level of industrial classification. It mentions that at 2-digit level of comparison, Pakistan's revealed competitive advantage (RCA) has been increasing due to increasing volume and value of footwear exports. The article also reveals that at four-level of classification, China has better RCA in all sub-sectors across the industry.

Hepatitis B (HBV) is one of the most common infectious diseases, with a worldwide annual incidence of over 250 million people. About one-third of the cases are in China. While China made significant efforts to implement a nationwide HBV vaccination program for newborns, a significant number of susceptible adults and teens remain. In this paper, we analyze a game-theoretical model of HBV dynamics that incorporates government-provided vaccination at birth coupled with voluntary vaccinations of susceptible adults and teens. We show that the optimal voluntary vaccination brings the disease incidence to very low levels. This result is robust and, in particular, due to a high HBV treatment cost, essentially independent from the vaccine cost. [ABSTRACT FROM AUTHOR]

This study's aim was to investigate iron (Fe) and zinc (Zn) concentration in the soil, forage crops, and sheep blood with respect to the seasonal availability of these metals. Soil, forage, and sheep blood samples were sampled from five different locations in Chakwal (Pidh, Tobar, Ratoccha, Choa Saiden Shah-Kalar Kahar road, and Choa Saiden Shan-Chakwal Road) during two seasons, i.e., winter and summer. All the samples were processed through wet acid digestion for evaluation of metal contents. Because of proximity of site-1 and site-2 to coal mines, higher Fe concentration was observed than Zn. Overall, varied Fe concentrations obtained in soil were 12.95-24.31 mg/kg, 1.29-9.61 mg/kg in forage and 1.17-24 mg/l in blood, whereas Zn values were 1.04-31.9 mg/kg, 1.96-7.02 mg/kg, and 0.16-6.52 mg/l for soil, forages, and blood respectively. The pollution load index value for both Fe (0.01-0.14 mg/kg) and Zn (0.02-0.72 mg/kg) was lesser than 1. Bio-concentration (0.09-2.64mg/kg) and enrichment factor (0.08-7.51 mg/kg) were showing efficient transfer of metals through the food chain. Daily intake and health risk index values of iron were ranged from 0.01 to 1.1 mg/kg/day and 0.02 to 1.05 mg/kg/day. There was a probable chance of upsurge in metal values in coming years due to continued mining activities. Anthropogenic input, mainly mining activities in the study area, have increased the Fe and Zn content in the environment which can ultimately find their way up the food chain, thereby risking the health of grazing livestock., (© 2021.

Background: The association between body mass index (BMI) and long-term outcomes of patients with ICC has not been well defined. We sought to define the presentation and oncologic outcomes of patients with ICC undergoing curative-intent resection, according to their BMI category., Methods: Patients who underwent resection of ICC were identified in a multi-institutional database. Patients were categorized as normal weight (BMI 18.5-24.9 kg/m 2 ), overweight (BMI 25.0-29.9 kg/m 2 ) and obese (BMI≥30 kg/m 2 ) according to the World Health Organization (WHO) definition. Impact of clinico-pathological factors on recurrence-free survival (RFS) was assessed using Cox proportional hazards model among patients in the three BMI categories., Results: Among a total of 790 patients undergoing curative-intent resection of ICC in the analytic cohort, 399 (50.5%) had normal weight, 274 (34.7%) were overweight and 117 (14.8%) were obese. Caucasian patients were more likely to be obese (66.7%, n = 78) and overweight (47.1%, n = 129) compared with Asian (obese: 18.8%, n = 22; overweight: 46%, n = 126) and other races (obese: 14.5%, n = 17; overweight: 6.9%, n = 19)(p < 0.001). There were no differences in the presence of cirrhosis (10.9%, vs. 12.8%, vs. 12.9%), preoperative jaundice (8.6% vs. 9.5% vs. 12.0%), or levels of CA 19-9 (75, IQR 24.6-280 vs. 50.9, IQR 17.9-232 vs. 43, IQR 16.9-192.7) among the BMI groups (all p > 0.05). On multivariable analysis, increased BMI was an independent risk factor for tumor recurrence (OR 1.16, 95% CI 1.02-1.32, for every 5 unit increase)., Conclusion: Increasing BMI was associated with incremental increases in the risk of recurrence following curative-intent resection of ICC. Future studies should aim to achieve a better understanding of BMI-related factors relative to prognosis of patients with ICC., (Copyright © 2019 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.
