Mapping Crop Rotation by Using Deeply Synergistic Optical and SAR Time Series

Crop rotations, the farming practice of growing crops in sequential seasons, occupy a core position in agriculture management, showing a key influence on food security and agro-ecosystem sustainability. Despite the improvement in accuracy of identifying mono-agricultural crop distribution, crop rotation patterns remain poorly mapped. In this study, a hybrid convolutional neural network (CNN) and long short-term memory (LSTM) architecture, namely crop rotation mapping (CRM), were proposed to synergize the synthetic aperture radar (SAR) and optical time series in a rotational mapping task. The proposed end-to-end architecture had reasonable accuracies (i.e., accuracy > 0.85) in mapping crop rotation, which outperformed other state-of-the-art non-deep or deep-learning solutions. For some confusing rotation types, such as fallow-single rice and crayfish-single rice, CRM showed substantial improvements from traditional methods. Furthermore, the deeply synergistic SAR-optical, time-series data, with a corresponding attention mechanism, were effective in extracting crop rotation features, with an overall gain of accuracy of four points compared with ablation models. Therefore, our proposed method added wisdom to dynamic crop rotation mapping and yields important information for the agro-ecosystem management of the study area.
Quantification of effects of climate change on flood in tropical river basins

Abstract Over the past two decades, southeastern Nigeria has witnessed huge economic losses due to severe flooding caused by climate change. Understanding the contribution of climate change to flooding is critical for runoff utilization and control, especially in the tropics. This study is focused on quantifying the amount of flooding contributed by climate change effects in the River Basin of southeastern Nigeria. First, the Climate-Flood model equation was expressed using the Time-Series Autoregressive model technique. Using Minitab software, mean annual values of contributing climate variables from prolonged periods of recorded data were investigated. Runoff predictions made from climate-flood models using only the annual records of climatic variables were filtered from the resultant of the respective annual climatic variables, and mean change in flood due to climate change. The output was analyzed considering geology, infiltration capacity, drainage lines and digital elevation model (DEM) of the area. The result shows the obvious trend in climatic variables consistently generates significant impact on the flood. Owerri had the highest positive change in evaporation of 0.11% with a rainfall of 0.03%. Awka had the highest change in sunshine hours and rainfall of 0.41%. Umuahia had the highest change in solar radiation of 0.08, while Enugu had the highest change in air temperature of 0.12. When the contribution of climate change to runoff variation was quantified, Enugu shows highest with 1.68 m3/s while Owerri has 0.04 m3/s. This knowledge is necessary in designing hydrological structures and formulating policies that will help prevent/mitigate flood disasters in the region.
The Effect of the Repair of Induced Articular Cartilage Defects in Pigs Using Calcium Phosphate Cement with Aminoacids on the Concentrations of Selected Inflammatory Markers and Serum Enzyme Activities

The repair of articular cartilage defects is an intensively developing area of research. Severe inflammatory reactions after surgical interventions on bones or their structures may lead to changes of bone or joint asymmetry. In laboratory diagnostics, some inflammatory biomarkers and serum enzymes are available for the evaluation of these inflammatory processes. A general understanding of inflammatory responses following the repair of cartilage defects is still lacking. The aim of this study was to describe the alterations in the values of five inflammatory markers and the activities of several enzymes in seven 5-month-old pigs within the first 30 days following the restoration of induced articular cartilage defects using the tetracalcium phosphate/nanomoneite cement powder enriched with amino acids (CAL). The reconstruction of surgically induced defects was accompanied by a significant increase of serum amyloid A (SAA, p < 0.05), haptoglobin (Hp, p < 0.001), C-reactive protein (CRP, p < 0.01), and pig major acute phase protein (pig-MAP, p < 0.001). Their concentrations decreased gradually within one-month post-surgery, the values recorded at the end of this period were higher than those obtained prior to surgery. The concentrations of α1-acid glycoprotein (AGP) showed no significant changes during the evaluated period. Alterations were also found in the enzyme activities of creatine kinase (p < 0.05), lactate-dehydrogenase and alkaline phosphatase (p < 0.01). These findings suggest that SAA, Hp, CRP and pig-MAP might be applicable biomarkers of acute phase response for the monitoring of postoperative period.
Identification of Delighters and Frustrators in Vegan-friendly Restaurant Experiences via Semantic Network Analysis: Evidence from Online Reviews

ABSTRACT The purpose of this paper is to provide an understanding of vegan-friendly restaurant customers’ experiences by investigating the “delighters” and “frustrators” characteristics. A qualitative approach is used to examine the semantic networks of vegan-friendly restaurant customers’ online reviews. Results indicate that salient factors which delight vegan-friendly restaurant customers relate to the attributes of vegan food and menus, social interaction, and unique characteristics of a vegan-friendly restaurant. By contrast, factors that frustrate vegan-friendly restaurant customers associate with perceived overpriced vegan foods, poor restaurant staff attitudes/negative service encounters, and hygiene issues. The results of this study have academic and practical implications through the use of an attribute performance model to understand the experiences of vegan restaurant customers. This research is an initial empirical attempt to thoroughly understand vegan-friendly restaurant experiences using big data.
Comparative Study on the Treatment of Leachate from a Mine Waste Dump with Two Agricultural Biowastes

Mining waste dumps are present all over the world. One of the main prob-lems of these solid deposits is the migration of heavy metals present in them due to the aqueous solutions flowing through them. The comparison of the removal of heavy metals from an aqueous solution of a real mining waste leachate under different conditions by two different agricultural wastes has been investigated. The effect of pH, contact time and dosage was studied using coffee grounds (CG) and walnut shells (WS), without pretreatment. The results obtained in the study showed the potential use of CG and WS for the removal of heavy metals, although the coffee grounds are the best adsorbents than the walnut shell.
Wage convergence after euro adoption - the case of Slovakia

According to the theory of integration, welfare increase is the long-term indirect effect of joining the euro area. Monetary integration accelerates the processes of economic convergence, including income convergence, which is particularly desired by the societies of catching-up economies. This process is crucial for increasing the long term potential for macroeconomic sustainable growth of the economy. The countries of the Visegrad Group are institutionally and structurally similar. But only Slovak Republik adopted euro in 2009, another Visegrad countries stay by their own currencies. So it is a good opportunity to assess the effects of joining the euro zone on wage growth in the medium term through a comparative analysis. The aim of the research is to assess the impact of joining the euro area on the wage growth rate in Slovakia. The research was carried out using the comparative method. Three types of convergence are taken into account: beta, sigma and gamma. An extension of the implementation of the concept of beta, sigma and gamma convergence is the estimation for variables other than GDP, i.e. for the wage growth rate. The analysis covers the 2009-2019 period. The study confirms the existence of beta and sigma convergence. The convergence of earnings between EU countries occurs, wages in less developed CEE countries, tend to grow faster than do in wealthier ones. On the other hand, no gamma convergence was found. The higher rate of wage growth in Slovakia as compared to other countries of the Visegrad group was also not confirmed.
Abiraterone Acetate for Metastatic Castration-Sensitive Prostate Cancer

The use of abiraterone acetate for the treatment of metastatic castration-sensitive prostate cancer is clinically effective. Compared with standard of care, abiraterone acetate was associated with increased overall survival, increased prostate cancer–specific survival, increased progression-free survival, and improved quality of life. Patients treated with abiraterone acetate were at higher risk for grade III to grade V adverse events (severe, life-threatening, or fatal) and were more likely to discontinue treatment compared with standard of care. The incremental cost-effectiveness ratios for both brand and generic abiraterone acetate were estimated to be higher than common willingness-to-pay thresholds.
Coupled Impacts of Atmospheric Circulation and Sea‐Ice on Late Pleistocene Terrigenous Sediment Dynamics in the Subarctic Pacific Ocean

Processes controlling environmental change in the subarctic Pacific Ocean on millennial to orbital timescales are not well understood. Here we use a 230‐kyr sedimentary record from the northwest Pacific Ocean to assess the response of late Pleistocene sediment dynamics to orbital forcing. Combining a source‐to‐sink perspective based on sedimentological records with climate model reanalysis, we reveal that fluctuations in sediment provenance were closely linked to obliquity‐forced changes in atmospheric circulation modes. Specifically, the position of the Aleutian Low controlled sediment transport from the Bering Sea and Aleutian Arc sources. Furthermore, a distinct shift in North Pacific ocean circulation during the Last Glacial Maximum may have been related to a strengthened Siberian High. The coincidence of atmospheric mode switches with changes in sea‐ice extent and North Pacific Intermediate Water formation in the marginal seas suggests that this coupled ocean‐atmosphere system may have acted as a regional amplifier of global climate variability.
No Story Without a Storyteller: The Impact of the Storyteller as a Narrative Element in Online Destination Marketing

Storytelling constitutes a promising tool in destination brand communication. Yet, although it also emerged as an important research field, studies on how individual story elements impact story persuasiveness are scant. This study investigates the impact of the storyteller as a narrative element (third person vs. first person) on tourist response. Findings show that first-person compared to third-person storytellers significantly increase engagement on social media, destination brand image, and tourist visit intentions. They further foster narrativity and social tone of text as well as tourist perceptions of narrative transportation and social presence. Processes of narrative transportation and social presence explain the effects of the storyteller on destination brand image and tourist visit intentions. Overall, the study expands our theoretical knowledge about organizational storytelling and supports destination managers in the design of effective destination brand stories.
Combatant socialization and norms of restraint: Examining officer training at the US Military Academy and Army ROTC

Can armed groups socialize combatants to norms of restraint – in essence, train soldiers to adopt norms of international humanitarian law on the battlefield? How can social scientists accurately measure such socialization? Despite being the central focus of organizational and ideational theories of conflict, studies to date have not engaged in systematic, survey-based examination of this central socialization mechanism theorized to influence military conduct. This study advances scholarly understanding by providing the first comparative, survey-based examination of combatant socialization to norms of restraint, using surveys and interviews with US Army cadets at the US Military Academy (USMA), Army Reserve Officer Training Corps (ROTC), and active duty Army combatants. Additionally, to better understand ‘restraint’ from combatants’ perspective, this study introduces the concept of the ‘combatant’s trilemma’ under which combatants conceptualize civilian protection as part of a costly trade-off with the values of military advantage and force protection. Survey results hold both positive and negative implications for socialization to law of war norms: military socialization can shift combatants’ preferences for battlefield conduct. However, intensive norm socialization may be required to shift combatants’ preferences from force protection to civilian protection norms. Study findings hold significant implications for understanding violence against civilians in conflict and for policies to disseminate civilian protection norms in armed groups worldwide.
First Commercial Semen Cryopreservation and Main Spermatological Features of Anatolian Buffalo

Conventional buffalo semen freezing studies are limited in Anatolian buffaloes, which are overly sensitive to exogenous stimulation. The present study's object was to determine the main features of Anatolian Buffalo semen obtained by artificial vagina method for the first time. A total number of 150 ejaculates were collected from three Anatolian Buffalo bulls (app. 4 years of age). The mean pH, volume and concentration of semen were found 6.63±0.15, 1.61±0.5 ml, 1629±222.67 x10 6 spermatozoa/ml, respectively. The sperm motion characteristics were determined by using a computer-assisted sperm analysis system (CASA); the total and progressively motile sperm values were 57.12±5.63%, 23.22±4.47% and other kinetic parameters such VAP, VSL, VCL, ALH, BCF, STR, LIN were found 94.71±8.48 µm/s, 72.6±7.08 µm/s, 160.9±15.66 µm/s, 7.8±3.75 µm, 29.15±1.56 Hz, 76.91±3.87%, 46.21±2.61%, respectively after thawing. Among buffalo bulls, differences in semen pH values were statistically significant (P<0.05), while differences in ejaculate volume, semen concentration, total motility, progressive motility, VAP, VSL, VCL, ALH, BCF, STR, and LIN

Reduction of flammability and improvement of thermal stability of polymers during heating can be achieved by the introduction of fillers. Epoxy composites filled with different loadings of multi-walled carbon nanotubes (MWCNTs) and expanded graphite (EG) were prepared. The thermal oxidation stability of the prepared samples was investigated under heating in an oxidizing atmosphere using thermal analysis. The hardness was measured using the Shore D hardness test. The flammability of the prepared composites was evaluated by the ignition temperature and time-to-ignition. It was found that there was a rise in temperature corresponding to a 5% weight loss during heating for both epoxy/MWCNT and epoxy/EG composites compared to neat epoxy resin. The Shore D hardness of epoxy/MWCNT composites increased with content growth up to 0.1 wt. % and decreased with further concentration rise. The addition of MWCNTs and EG leads to an increase in the ignition temperature. It has been shown that MWCNTs improve the thermal behavior of epoxy resin in a low temperature region (below ~ 300 °C) whereas EG shows almost the same thermal behavior above 300 °C. The improvement of thermal properties can be achieved using MWCNTs and EG as fillers.
The Impact of Chatbots on the Relationship between Integrated Marketing Communication and Online Purchasing Behavior in The Frontier Market

Artificial Intelligence (AI), applied in many fields, is the core of the fourth technological revolution. In business, AI is used for customer relationship management as applied in the autoresponder systems, i.e., chatbot. Chatbots were an essential tool in the marketing relationship as many companies applied this function to their website; hence, this study analyzed the influence of chatbots on the enterprise's integrated marketing communication (IMC) activities, resulting in impulse purchase behavior and repurchase intention behavior. The mixed research method was used, particularly the in-depth interview and the survey with 886 online consumers, who shop from the online websites with chatbots system in Vietnam as Tiki, Lazada, Sendo, excetera. The research results showed that the perceived usefulness and ease of use of chatbots have positively affected the attitude of online consumers to the IMC activities of businesses. Simultaneously, IMC leads to impulse buying as well as the repurchase intention behavior of customers. The study proposed some managerial implications for an online business to enhance the chatbot functions to consumer behaviors in the website.
Attentional load effects on emotional content in face working memory

This study investigated the role of attentional resources in processing emotional faces in working memory (WM). Participants memorised two face arrays with the same emotion but different identities and were required to judge whether the test face had the same identity as one of the previous faces. Concurrently during encoding and maintenance, a sequence of high- or low-pitched tones (high load) or white noise bursts (low load) was presented, and participants were required to count how many low-tones were heard. Experiments 1 and 2 used an emotional and neutral test face, respectively. The results revealed a significant WM impairment for sad and angry faces in the high-load versus low-load condition but not for happy faces. In Experiment 1, participants remembered happy faces better than other emotional faces. In contrast, Experiment 2 showed that performance was poorer for happy than sad faces but not for angry faces. This evidence suggests that depleting attentional resources has less impact on WM for happy faces than other emotional faces, but also that differential effects on WM for emotional faces depend on the presence or absence of emotion in the probe face at retrieval.
Carbon, Nutrients and Methylmercury in Water from Small Catchments Affected by Various Forest Management Operations

Forest management activities in boreal and hemiboreal environments have been found to increase the concentration of carbon, nutrients, and methylmercury (MeHg) in runoff water, thus contributing to environmental quality issues. We evaluated carbon, nutrient, and MeHg concentrations in water at eight small, forested catchments on organic soils in Latvia, subject to ditch cleaning and beaver dam removal. These management-induced disturbances were classified into a major, minor, or no disturbance classes. The concentrations of dissolved organic carbon and total nitrogen were elevated in disturbed catchments (both major and minor) compared to the catchments with no disturbance. The concentrations of MeHg in the water displayed a clear seasonal variation with higher concentrations in spring and summer, but there were no significant differences in MeHg concentrations between catchments with major, minor, and no disturbances. However, the higher concentrations of SO42− in the disturbed catchments compared to those undisturbed may promote MeHg formation if the conditions become more reduced further downstream. While most former studies of forest management effects on water quality have focused on forest harvest, our research contributes to the currently rather scarce pool of data on the impact of less-studied management operations, such as ditch cleaning and beaver dam removal, on carbon, nutrient, and MeHg concentrations in runoff water.
INTERNATIONAL STUDENTS’ BURNOUT IN HIGHER EDUCATION

International student mobility has been expanding in the past twenty years. Creating economic value and strategic colloborations, developing a common understanding in a socio-cultural context, and generating scientific knowledge at a universal level through projects and research in higher education are the main reasons that play a role in the increase of internationalization efforts. International students who prefer to study outside of their country face many academic, socio-cultural, psychological and economic problems. The purpose of this study is to determine the burnout levels of international students. A descriptive approach incorporating quantitative (MBI-SS) and qualitative methods (semi structured interviews) were adopted in the present study to collect data. A total of 1284 international students were selected fort the quantative and 20 studets for the qualitative part of the study. The results of the study revealed the fact that international students has high burnout levels due to academic demands, cultural differences, financial problems, language and homesickness.
