Abstract:
The number of grains per panicle significantly contributes to rice yield, but the regulatory mechanism remains largely unknown. Here, we reported a loss-of-function mutant, panicle apical abortion 7 (paa7), which exhibited panicle abortion and degeneration of spikelets on the apical panicles during the late stage of young panicle development in rice. High accumulations of H2O2 in paa7 caused programmed cell death (PCD) accompanied by nuclear DNA fragmentation in the apical spikelets. Map-based cloning revealed that the 3 bp “AGC” insertion and 4 bp “TCTC” deletion mutation of paa7 were located in the 3′-UTR regions of LOC_Os07g47330, which was confirmed through complementary assays and overexpressed lines. Interestingly, LOC_Os07g47330 is known as FRIZZY PANICLE (FZP). Thus, PAA7 could be a novel allele of FZP. Moreover, the severe damage for panicle phenotype in paa7/lax2 double mutant indicated that PAA7 could crosstalk with Lax Panicle 2 (LAX2). These findings suggest that PAA7 regulates the development of apical spikelets and interacts with LAX2 to regulate panicle development in rice.

Abstract:
The influence of panicle maturity on oviposition by the corn earworm, Helicoverpa zea (Boddie), and sorghum webworm, Celama sorghiella (Riley), was investigated on grain sorghum in Georgia during 1986 and 1987. Stage of panicle development, density of corn earworm and sorghum webworm, and egg parasitism by Trichogramma spp. were recorded at 2–3 day intervals in three field tests. Sorghum webworm and corn earworm began oviposition as panicles emerged from the boot. Oviposition peaked 4–8 days later, near the time panicles began anthesis, but then declined quite rapidly. Oviposition by sorghum webworm ceased approximately 10–12 days after panicle emergence began. Corn earworm oviposition continued at low levels until sampling was terminated 14 - 17 days after panicles began emgergence. Rainfall appeared to mediate effects of panicle maturity on oviposition. Corresponding peaks in larval density were not observed for corn earworm or sorghum webworm, possibly because of heavy parasitism by Trichogramma spp. A paired comparison procedure was used to determine preference of small, medium, and large corn earworm larvae for panicles of different maturity. Early instars preferred newly flowered panicles and concentrated feeding on pollen filled anthers. Late instars preferred panicles in the soft-hard dough stages, while intermediate instars exhibited no significant preference. These data suggest that corn earworm oviposition is concentrated at anthesis because pollen enhances larval development and survival.

Abstract:
The pattern of panicle and flower development of lychee (Litchi chinensis Sonn.) trees was studied in subtropical Queensland (lat. 27�S.). The cultivars studied were Tai So at 3 sites, Bengal at 4 sites, Kwai May Pink at 2 sites, Salathiel at 3 sites, and Wai Chee at 2 sites. Tai So was the earliest cultivar, with panicle emergence in late May and flower anthesis in mid September. The other cultivars were 5-7 weeks later. Tai So had a longer period of flower anthesis than the other cultivars (4 weeks v. 1-3 weeks). Cultivars Tai So and Bengal generally had longer panicles than cvv. Kwai May Pink, Salathiel and Wai Chee (17-32 v. 10-14 cm), and more flowers per panicle (1800-3400 v. 400-900). Similarly, the number of fruit per panicle ranged from 7-33/panicle 2-3 weeks after the end of flowering, to 4-22/panicle at harvest. The proportion of female flowers setting fruit ranged from 2.1 to 19.5%. Similar estimates for fruit carried to harvest ranged from 0.8 to 6.8%. Variations in the times of panicle emergence, panicle development, and anthesis among the cultivars in relation to seasonal progressions in temperature affected the number of fruit set. The number of fruit set per panicle increased as the number of female flowers per panicle increased. Higher numbers of female flowers were associated with maximum temperatures during flower development of 18�C, with lower numbers at 23�C. Higher maximum temperatures during anthesis (30�C v. 24�C) increased the proportion of female flowers setting fruit.

Abstract:
A new rice strain that grows six feet tall with four times higher potential yield than the conventionally bred variety, JP5, was developed using the MAGIC approach. This new rice type underwent analysis on sink size and source capacity traits, including superior and inferior spikelets, vascular bundles of panicle neck and stem internode, tillering pattern, grain filling pattern, yield, and other morphological attributes. Results indicated that the new strain had more vascular bundles of the stem (42) and panicle neck (35), primary rachis branches of panicle (16.1), superior spikelets, and greater grain weight than the conventionally bred variety, JP5. The panicle measured 45 cm long, with fertile grains of 500 per panicle and a stem diameter of 1.2 cm. During the grain filling duration, the spikelets of this strain and superior spikelets of JP5 gained maximum weight earlier than the inferior spikelets of JP5. Six feet tall plants of this new strain with long and heavy panicles had greater stem wall thickness. There occurred a positive and significant correlation (0.97) between yield and small vascular bundles of the panicle neck, lumen diameter (0.98), leaf length (0.99), leaf width (0.99), flag leaf length (0.99*), flag leaf width (0.97<), panicle length (0.97), fertile grains per panicle (0.98), and plant height (0.97*). The study noted that improving sink size, source capacity, and transportation of assimilation contributed positively toward yield. This novel strategy for grain yield enhancement in rice proved beneficial for other cereals to get significant breakthroughs in their production for ensuring food security.

Abstract:
As a staple food, rice can be used as a bio fortification. For this necessity, Indonesian Agency for Agriculture Research and Development (IAARD) developed rice variety which was rich of Zn content to overcome child stunting. To understand the panicle branching behavior of Inpari IR Nutri Zinc, we collected panicle branching data from different sites and agronomical practices. Data were collected from three locations in West Java, i.e Cianjur, Majalengka, and Ciamis during May until October 2020. Among sites showed a significant differences of panicle branching. The best performance of Inpari IR Nutri Zinc panicle branching was showed at Majalengka rather than Ciamis and Cianjur. It was predicted because of temperature differences, as Cianjur’s was higher than those Majalengka’s and Ciamis’. Based on planting space, L5 was better than that L2 in number of grains per panicle, number of primary branches, number of secondary branches, total length of primary branches, and number of filled-grain per panicle characters. Meanwhile, L2 in Majalengka and Ciamis showed higher value in three panicle branching characters. Further, the L2 in Majalengka showed higher value and significantly difference than that in Ciamis in seven panicles branching characters bio pesticide application also affected some panicle branching characters significantly.

Abstract:
Hybrid seed set on the female line depends primarily on its flowering synchronization with the restorer line (R), therefore, the sowing of male and female lines must be planned properly to achieve this. Field experiments on different sowing dates (May 1st, May 15th, and May 30th) of R lines (Giza 178R, Giza 179R, and Giza 181R) and cytoplasmic male sterile (CMS) lines (IR69625A, IR70368A, IR58025A, K17A, and G46A) were carried out at the farm of Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt during 2019 and 2020 to study the effect of sowing dates on flowering synchronization in hybrid rice. The results indicated that the synchronization of flowering between CMS lines and R lines has highly significant effects on the days to 50% heading, number of leaves, effective accumulated temperature (EAT), plant height, panicle exertion percentage, panicle length, number of fertile panicles, panicle weight, seed set percentage, harvest index and seed yield of hybrid rice. The highest seed yield (1.72 and 1.41 t ha−1, respectively in 2019 and 2020) was recorded from the sowing date May 1st and the hybrid combination of Giza 178R × IR58025A (2.06 and 2.12 t ha−1 in 2019 and 2020, respectively). The grain yield had a significant and highly significant positive correlation with the plant height (cm), panicle exertion percentage, panicle length, number of panicles plant−1, panicle weight, seed set percentage, and harvest index. In Egypt, May 1st is the best time for the synchronization of hybrid rice lines and a combination of Giza 178R × IR58025A may be recommended for better performance.

Abstract:
Outcomes of developmental yield formation processes in oats, namely number of panicles/m2, number of grains/panicle, mean grain weight and incidences of aborted and tertiary grains, were measured in a series of experiments in Northern Ireland and the Republic of Ireland in 1997/98 and 1998/99. Seed rate (200 and 300 seeds/m2), nitrogen (0–200 kg/ha) and plant growth regulator (chlormequat chloride) treatments were applied to the spring oat varieties Aberglen and Barra in one spring- and two autumn-sown experiments, and to the winter varieties Gerald and Image in one autumn-sown experiment. Large variation in number of panicles/m2 and grains/panicle was observed between the experiments and varieties and in response to seed rate, with number of grains/panicle generally being inversely related to number of panicles/m2. At the higher rates of nitrogen rate both number of panicles/m2 and grains per panicle increased. Mean grain weights were relatively constant and were largely determined by variety. Chlormequat chloride had relatively little effect on the yield components, the most consistent being small reductions in mean grain weight.Tertiary grains occurred rarely in the varieties and agronomic treatments used in the programme but were more frequent at higher rates of nitrogen in most of the experiments. Numbers of aborted grains were usually higher where grain numbers were higher although the effects of variety, seed rate and nitrogen on aborted grains were not consistent. Structure of the grain population, i.e. the relative proportions of primary and secondary grain, was stable despite the large differences in number of panicles/m2, spikelet numbers and mean grain weight.The greater yield and growth enhancing effects of nitrogen compared with seed rate and plant growth regulator were apparent in responses by developmental processes active later in the life cycle, namely production of tertiary grains and grain filling.Wide variation in number of panicles/m2 (c. 200–450) and number of grains/panicle (c. 55–145) produced in the crops grown under a very full expression of agro-ecological conditions in this programme was accompanied by small variation in mean grain weight (c. 38–47 mg/primary grain and c. 22–29 mg/secondary grain) and in numbers of tertiary (<2/panicle) and aborted grains (<10/panicle). Plasticity of development throughout the life cycle, manifested both as the established yield components and in numbers of tertiary and aborted grains, was largely effective in ensuring stability of mean grain weight and quality in oats.

Abstract:
Heat stress inhibits rice panicle development and reduces the spikelet number per panicle. This study investigated the mechanism involved in heat-induced damage to panicle development and spikelet formation in rice cultivars that differ in heat tolerance. Transcriptome data from developing panicles grown at 40 °C or 32 °C were compared for two rice cultivars: heat-tolerant Huanghuazhan and heat-susceptible IR36. Of the differentially expressed genes (DEGs), 4,070 heat stress-responsive genes were identified, including 1,688 heat-resistant-cultivar-related genes (RHR), 707 heat-susceptible-cultivar-related genes (SHR), and 1,675 common heat stress-responsive genes (CHR). A Gene Ontology (GO) analysis showed that the DEGs in the RHR category were significantly enriched in 54 gene ontology terms, some of which improved heat tolerance, including those in the WRKY, HD-ZIP, ERF, and MADS transcription factor families. A Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that the DEGs in the RHR and SHR categories were enriched in 15 and 11 significant metabolic pathways, respectively. Improved signal transduction capabilities of endogenous hormones under high temperature seemed to promote heat tolerance, while impaired starch and sucrose metabolism under high temperature might have inhibited young panicle development. Our transcriptome analysis provides insights into the different molecular mechanisms of heat stress tolerance in developing rice.

Abstract:
Highlights An experimental platform for the kinematic characteristics of panicles was constructed. A regression model for the kinematic characteristics of panicles and working parameters was established. The multi-objective optimization based on the kinematic characteristics of rice panicles was carried out. The optimized combination of working parameters was verified by field pollination experiments. Abstract. Pollen shedding and dispersal processes are inextricably linked to the movement state of hybrid rice panicles. The purpose of this work was to study the effect of the working parameters of the pneumatic pollinator on the kinematic characteristics of hybrid rice panicles during flowering and to further optimize the working parameters of the pollinator. An experimental platform was built to characterize the movement of the panicle. Orthogonal experiments were conducted with airflow velocity, action position, and walking speed as experimental factors and kinematic parameters such as displacement, velocity, and acceleration of the rice panicle as experimental indicators. A quadratic regression model between the working parameters and the motion characteristics of the rice panicle was constructed and analyzed by analysis of variance (ANOVA). Matrix analysis was used for multi-objective optimization of the working parameter combinations. Field pollination trials were conducted for the optimized combination of parameters. The results showed that the coefficients of determination of the regression models were all above 0.85, which indicated good accuracy. The motion characteristics of the panicle, including the displacement maximum, velocity maximum, and acceleration maximum, can be maintained at a high level when the airflow velocity is 24 m/s, the action position is 120 mm from the top of the panicle, and the walking speed is 0.4 m/s. The field experiments showed that the optimization results could obtain the desired pollen density, distribution, and uniformity. This study can serve as a reference for the development of pneumatic hybrid rice pollination theory and the optimal design of the pollinator structure.

Abstract:
Panicle morphology is one of the main determinants of the rice yield. Panicle abortion, a typical panicle morphological defect results in yield reduction due to defective spikelet development. To further elucidate the molecular mechanism of panicle abortion in rice, a rice panicle bald head 1 (rbh1) mutant with transfer DNA (T-DNA) insertion showing severely aborted apical spikelets during panicle development was identified and characterized. The rbh1-1 mutant showed obviously altered cell morphology and structure in the degenerated spikelet. Molecular genetic studies revealed that RBH1 encodes a pectate lyase protein. Pectate lyase-specific activity of Rice panicle Bald Head 1 (RBH1) protein assay using polygalacturonic acid (PGA) as substrates illustrated that the enzyme retained a significant capacity to degrade PGA. In addition, immunohistochemical analysis showed that the degradation of pectin is inhibited in the rbh1-1 mutant. Further analysis revealed that a significant increase in reactive oxygen species (ROS) level was found in degenerated rbh1-1 spikelets. Taken together, our findings suggest that RBH1 is required for the formation of panicle and for preventing panicle abortion.

Abstract:
The transition from a vegetative phase to a reproductive one has always been deeply studied in plants and in particular in the cereals due to the relevance of this trait for seed yield. The transition occurs upon the arrival of a mobile flowering signal, the florigen, at the shoot apical meristem (SAM). In rice (Oryza sativa), there are two different florigens: Heading Date 3a (Hd3a), that promotes flowering in short day (SD) conditions and Rice Flowering Locus T 1 (RFT1) that promotes flowering in both short and long- days (LD). They are transcribed and translated in leaves once environmental conditions are optimal, and then transported through the phloem to the SAM. After reaching the shoot they form a heterohexameric complex named Florigen Activation Complex (FAC) binding to two 14-3-3 proteins and to two bZIP transcription factors and activate conversion of the shoot apex into an inflorescence by promoting expression of inflorescence- identity genes. Here, we show that Hd3a and RFT1 arrival at the SAM activates FLOWERING LOCUS T-LIKE 1 (FT-L1), encoding a third florigen-like protein showing atypical characteristics. Expression data from qRT-PCR, in situ hybridization and transcriptional marker lines indicated that its mRNA is mainly expressed in the SAM and persists during all developmental stages of inflorescence development. Misexpression of FT-L1 from meristem- and tissue-specific promoters indicates that only when expressed in the SAM, FT-L1 has florigenic activity. Isolation and analysis of EMS and CRISPR mutants showed that FT-L1 strengthens the effects of Hd3a and RFT1 during conversion of the vegetative meristem into inflorescence, in an addictive manner. Furthermore, it controls panicle branching by inhibiting secondary branching and promoting spikelet meristem differentiation. Thus, we propose a triple florigenic module that promotes a balanced progression of inflorescence identity and determinacy.

Full text
Abstract:

Much of plant growth is directly or indirectly regulated by the plant hormone auxin. Although some genes involved in the auxin pathway have been characterized, there are still gaps in our knowledge of this genetic pathway. Recently, the orthologous maize genes BARREN STALK2 ( BA2) and rice gene LAX PANICLE2 (LAX2) have been cloned and characterized. Maize ba2 and rice lax2 mutant plants both show significant flaws in axillary meristem (AM) initiation, suggesting a role in auxin regulation. In support of this hypothesis, LAX2 interacts with the auxin regulating LAX PANICLE1 (LAX1) protein. My research reconstructs the evolutionary history of the BA2/LAX2 lineage and tests for conservation of BA2/LAX2 mRNA expression in diverse grasses. My results indicate that the BA2/LAX2 gene family—comprising BA2 /LAX2, BA2/LAX2-Like1 (BA2/LAX2L1), and BA2/ LAX2-Like2 (BA2/LAX2L2)—is restricted to monocots, and shows evidence of two independent gene duplication events. During its evolution, the BA2/LAX2 gene family appears to have gained a PDZ Protein Binding motif, which may allow it to interact with other proteins besides BA1/ LAX1. My expression analyses show that BA2/ LAX2 genes are expressed during multiple stages of inflorescence development, and this expression is conserved across multiple grass species. A unique floral expression pattern appears to have evolved at the base of the Joinvilleaceae lineage. My study further supports the hypothesis that BA2/LAX2 genes are functioning in multiple AM pathways.

Abstract:
Excessive use of fossil fuels to meet everyday energy demands has led to adverse environmental impacts like global warming and high dependence on foreign oil. Development of cellulosic feedstocks provides energy security and also reduces the burden on food crops like corn and sugarcane used for ethanol production. This thesis uses cost-benefit analysis to ascertain the profitability of producing cellulosic ethanol from Switchgrass and Sweet Sorghum Bagasse. First, breakeven price of producing Switchgrass and Sweet Sorghum is calculated to obtain a raw material (feedstock) cost for ethanol production. Next, net present value (NPV) and minimum ethanol selling price (MESP) for Switchgrass and Sweet sorghum are calculated. Lastly, risk analysis is performed and its impacts on NPV are calculated for two farmer categories. The results show that ethanol production from Switchgrass and Sweet Sorghum is commercially feasible and generates a Net Present Value (NPV) of $39.54 million for Switchgrass and $96.76 million for Sweet Sorghum at an ethanol selling price of $2.17 per gallon. At NPV zero the MESP for Switchgrass and Sweet Sorghum is estimated to be $2.10 and $1.96 per gallon respectively. The risk analysis results revealed that there is a 9.5 percent probability that the NPV for a risk-averse Switchgrass farmer will be less than zero. On the other hand, the probability of the NPV being less than zero is 67.4 percent. The overall analysis indicates that ethanol production from Switchgrass and Sweet Sorghum is a promising option. Reduction in feedstock prices, optimization of the conversion process and additional revenues from by-products can make cellulosic ethanol more competitive with current gasoline prices.

Abstract:
This thesis presents the current analysis technique applied to certain psychology data and outlines alternative engineering approaches to such analysis. Current research on panic disorder involves data measurement and analysis of many physiological, neuro-chemical and psychological variables. Due to the complexity of and little knowledge about the human body, there are no firm theories on what actually gives rise to these variables, ie. what results in a rise in negative cognition or distress level. Current studies [1, 2] have reported that the patients cognitive responses tend to be more closely related to the distress level than other quantities and the heart rate is related to the distress level but on a smaller scale. However, the conclusions drawn from the results were not definitive. Engineering analysis techniques carried out indicated that the cognitions of the patients play an important role in the mechanisms of panic. This thus confirmed the results obtained by current studies in a more rigorous manner.

Full text
Abstract:
This study combines moral panic with the figurational sociology of Norbert Elias to explore how climate change has developed as a social problem. The central argument is that,through combining the short-term focus of moral panic with the long-term focus of Elias, we can examine the interplay between planned and unplanned developments in both the perception and reality of climate change. The first part of the research consisted of discourse analysis of a variety of different texts from 1800 to the present. These were used to explore the long-term development of climatechange as emerging from an ecological civilizing process. The second stage of the research related these developments to moral panics, arguing that the emergence of climate change can only be understood by exploring the interplay between long-term processes and short-term campaigns. The third part of the research explored these historical developments at the individual level, examining the notion of individual ecological civilizing processes. 15 semi-structured interviews were undertaken with climate change ‘activists’ and ‘non-activists’, comparing how their biographical developments related to ecological civilizing processes and moral panics. The final part of the research compared climate change with five other empirical examples of moral panics, to explore the civilizing and decivilizing processes and civilizing offensives that occur before, during, and after the panics. The central aim was to demonstrate the complexity of moral panics, and to aid in the reformulation of the concepts of moral panic and decivilization. Through a synthesis of Elias and moral panic, as applied to the example of climate change, this study aimed to: critically assess the development of climate change; to reassess the concept of decivilization and the relation between civilizing processes and offensives; and to reformulate the concept of moral panic, including suggesting how moral panic research ought to be undertaken.

Abstract:
To decrease dependency of fossil fuels and avoid direct competition with food crops, massive research efforts are investigating next-generation cellulose biofuel crops such as switchgrass (Panicum virgatum). A low-input, sustainable switchgrass production could be achieved by reducing traditional management practices though applying plant growth promoting rhizobacteria (PGPR), of which our understanding is still rather limited. To elucidate physiological mechanisms behind PGPR's beneficial effects, we inoculated switchgrass seedlings with Burkholderia phytofirmans strain PsJN. Two experiments were conducted to determine the initial and long-term responses of switchgrass to PsJN inoculation by tracking growth and leaf physiology. In a third experiments, we tested the effects of PsJN on growth and leaf-level physiology of switchgrass under a moderate pre-drought conditioning and a successive severe drought stress. PsJN inoculation increased biomass and promoted elongation of shoots within 17 days following inoculation. The enhanced root growth in PsJN inoculated plants lagged behind the shoot response, resulting in greater allocation to aboveground growth (p=0.0041). Lower specific root length (p=0.0158) and higher specific leaf weight (p=0.0029) were also observed in PsJN inoculated seedlings, indicating advanced development. Photosynthetic rates (Ps) were higher in PsJN inoculated seedlings after 17 days (54%, p=0.0016), which were related to higher stomatal conductance, greater water use efficiency, and lower non-stomatal limitation of Ps. These rapid changes in leaf physiology are at least partially responsible for switchgrass growth enhancement from PsJN treatment. The early growth enhancement in PsJN inoculated switchgrass linearly decreased with plant age. PsJN inoculation increased Ps of upper canopy leaves by 13.6% but reduced Ps of lower canopy leaves by 8.2%. Accelerated leaf senescence and early flowering were observed in PsJN-inoculated switchgrass, which might contribute to slightly lower aboveground biomass at final harvesting. Drought preconditioning increased Ps of PsJN-inoculated switchgrass during a later severe drought; whereas, control switchgrass only benefited from drought preconditioning when leaf water potential dropped below -1 MPa. This study verified early growth enhancement and accelerated development of switchgrass due to PsJN inoculation. Rapid improvement in leaf physiology is related to enhanced productivity. PsJN inoculation also improve drought tolerance of switchgrass.

Abstract:
AbstractHumanity is experiencing a moment of great uncertainty. This is not the first time a pandemic threatens the lives of millions of people. However, the speed with which governments and scientists are reacting to events is unprecedented. In an incredibly short time after the discovery of the virus, public health measures were implemented, and the development of defences in the form of public policies, medical therapies, and vaccines began. At this precarious moment, when the proliferation of information (and misinformation) from a variety of sources contribute to the spread of panic, universities and the scientific community emerge as the best and most reliable sources of information. It is only highly qualified specialists who can truly address the pandemic and its terrible economic, political, and public health consequences.

Abstract:
Nuclear safety attracts many concerns from society especially after Fukushima accident. In recent years, although nuclear safety system has been continuously improved on the aspects of design functions, safety standards and safety assessment methods, etc., the public panic has not been reduced correspondingly. In some countries and regions, the public nuclear panic has a strong impact on the sustainable development of nuclear energy, which has been widely recognized by nuclear industries worldwide. In this paper, we studied the nuclear public panic from three aspects with the analysis of psychological and sociological methods, including: (1) Discussing the source of nuclear panic in the sense of Maslow’s hierarchy of needs and psychoanalysis; (2) Systemically studying the irrational behaviors in nuclear accidents and the public nuclear culture with cognitive theory; (3) Giving out the general model of public nuclear panic. In the last, some suggestions of nuclear risk perception and communication were also shown as reference, which are significant for the future work.

Abstract:
Fukushima nuclear accident aroused large-scale public panic toward nuclear power development. Due to the limit knowledge of nuclear power, some people feel frightened and fearful for nuclear safety, nuclear radiation as well as nuclear accident. As the energy with clean, stable and high-efficiency, nuclear power always takes imperative and irreplaceable role in Chinese energy program. Therefore, public acceptance and basic knowledge towards nuclear power in post-Fukushima era is facing new unprecedented challenge. How to relieve the panic and frightening of the public and recover the confidence of nuclear power safety is gradually becoming the hot issue among public. This paper makes detailed investigations of current public mental in China toward nuclear power in post-Fukushima era, analyzes the internal and external causes of the panic feeling and further proposes several countermeasures and suggestions accordingly for safe and health development of nuclear power in China.

Abstract:
ABSTRACT This presentation discusses student engagement and academic integrity as well as the responsibility of the educator based on insights gained through personal experience of teaching writing courses at an undergraduate level at Deree – The American College of Greece. The student body at Deree is diverse, consisting of students from Greece and 56 countries and regions, with English being the language of instruction. Research has shown that the demands of attending a foreign university can push students toward breaches of academic integrity. The overall question this presentation addresses is what insights educators gained through virtual classes held March 2020 up to June 2021, and the subsequent return to campus in September 2021. More specifically, the presentation explores the effects of this return on students’ academic performance and integrity as well as the role of the educator in encouraging student morale and morality while respecting mental health challenges. The initial hypothesis of this presentation was that the return to campus would be perceived as a joyous event, inspiring students to engage in their studies with more zest. However, personal observations indicate that the initial excitement and enthusiasm have turned into frustration, even panic, with students often falling behind with their assignments as well as disregarding feedback, course and college policies. On their side, and owing to their own mental and emotional exhaustion, fear of complaints, or compassion for the student, instructors might accept work potentially written by a ghost writer. This presentation stresses the need for educators to pull students toward authentic learning and offers some suggestions as to how to achieve a balance between respecting students and promoting academic performance.

Abstract:
The interaction between driver and vehicle is analyzed in the paper. The driver acts on the steering wheel to modify the trajectory and to control the vehicle during panic situations. The knowledge of the forces exerted by the driver at the steering wheel is useful for a better understanding of the driver steering action. The final aim is to inspire the development of haptic steering wheels for better tuning of Advanced Driver Assistance Systems (ADAS). An instrumented steering wheel has been used, which includes two six axis load cells to measure the forces and the moments exerted by the driver hands and six sensors used to measure the grip strength. Two maneuvers have been considered, a moderate speed turn and a kick plate test which simulates a panic situation with an impulsive lateral disturbance. For both of the two considered situations, some common driving behaviors have been highlighted and analyzed. The preliminary results encourage the development of haptic instrumented steering wheels, able to improve ADAS. Actually it seems possible to infer the driver steering purpose before the steering wheel is actually rotated.

Abstract:
This article tells about my own experiences as a student and professor in technical education in Norway and USA in the 1980s and 90s, and economic education in Norway the academic year 2000-01. In technical education in Norway in the 1980s it was not necessary to put that much effort into your studies get a good grade. In the United States, on the other hand, students had two work hard to keep up to get good results. Norwegian higher education, however, has become more like American higher education after the Bologna process. A fresh university professor is nothing more than an advanced student, in the beginning one sticks to the textbook, and any deviation from the plan can cause light panic. As time goes by, the professor gains experience and growing self-confidence, and can start to experiment. My journey in teaching control engineering ended up with flipped classroom, based upon sociocultural learning, where both students and professors participate with the knowledge they have. Learning happens best if people interact and construct new knowledge together. The participants in the learning environment extend their closest (proximal) development zone by collaborating with others.

Full text
Abstract:
Background: Public behaviour and the new hostile threats • Civil contingencies planning and preparedness for hostile threats requires accurate and up to date knowledge about how the public might behave in relation to such incidents. Inaccurate understandings of public behaviour can lead to dangerous and counterproductive practices and policies. • There is consistent evidence across both hostile threats and other kinds of emergencies and disasters that significant numbers of those affected give each other support, cooperate, and otherwise interact socially within the incident itself. • In emergency incidents, competition among those affected occurs in only limited situations, and loss of behavioural control is rare. • Spontaneous cooperation among the public in emergency incidents, based on either social capital or emergent social identity, is a crucial part of civil contingencies planning. • There has been relatively little research on public behaviour in response to the new hostile threats of the past ten years, however. • The programme of work summarized in this briefing document came about in response to a wave of false alarm flight incidents in the 2010s, linked to the new hostile threats (i.e., marauding terrorist attacks). • By using a combination of archive data for incidents in Great Britain 2010-2019, interviews, video data analysis, and controlled experiments using virtual reality technology, we were able to examine experiences, measure behaviour, and test hypotheses about underlying psychological mechanisms in both false alarms and public interventions against a hostile threat. Re-visiting the relationship between false alarms and crowd disasters • The Bethnal Green tube disaster of 1943, in which 173 people died, has historically been used to suggest that (mis)perceived hostile threats can lead to uncontrolled ‘stampedes’. • Re-analysis of witness statements suggests that public fears of Germany bombs were realistic rather than unreasonable, and that flight behaviour was socially structured rather than uncontrolled. • Evidence for a causal link between the flight of the crowd and the fatal crowd collapse is weak at best. • Altogether, the analysis suggests the importance of examining people’s beliefs about context to understand when they might interpret ambiguous signals as a hostile threat, and that. Tthe concepts of norms and relationships offer better ways to explain such incidents than ‘mass panic’. Why false alarms occur • The wider context of terrorist threat provides a framing for the public’s perception of signals as evidence of hostile threats. In particular, the magnitude of recent psychologically relevant terrorist attacks predicts likelihood of false alarm flight incidents. • False alarms in Great Britain are more likely to occur in those towns and cities that have seen genuine terrorist incidents. • False alarms in Great Britain are more likely to occur in the types of location where terrorist attacks happen, such as shopping areass, transport hubs, and other crowded places. • The urgent or flight behaviour of other people (including the emergency services) influences public perceptions that there is a hostile threat, particularly in situations of greater ambiguity, and particularly when these other people are ingroup. • High profile tweets suggesting a hostile threat, including from the police, have been associated with the size and scale of false alarm responses. • In most cases, it is a combination of factors – context, others’ behaviour, communications – that leads people to flee. A false alarm tends not to be sudden or impulsive, and often follows an initial phase of discounting threat – as with many genuine emergencies. 2.4 How the public behave in false alarm flight incidents • Even in those false alarm incidents where there is urgent flight, there are also other behaviours than running, including ignoring the ‘threat’, and walking away. • Injuries occur but recorded injuries are relatively uncommon. • Hiding is a common behaviour. In our evidence, this was facilitated by orders from police and offers from people staff in shops and other premises. • Supportive behaviours are common, including informational and emotional support. • Members of the public often cooperate with the emergency services and comply with their orders but also question instructions when the rationale is unclear. • Pushing, trampling and other competitive behaviour can occur,s but only in restricted situations and briefly. • At the Oxford Street Black Friday 2017 false alarm, rather than an overall sense of unity across the crowd, camaraderie existed only in pockets. This was likely due to the lack of a sense of common fate or reference point across the incident; the fragmented experience would have hindered the development of a shared social identity across the crowd. • Large and high profile false alarm incidents may be associated with significant levels of distress and even humiliation among those members of the public affected, both at the time and in the aftermath, as the rest of society reflects and comments on the incident. Public behaviour in response to visible marauding attackers • Spontaneous, coordinated public responses to marauding bladed attacks have been observed on a number of occasions. • Close examination of marauding bladed attacks suggests that members of the public engage in a wide variety of behaviours, not just flight. • Members of the public responding to marauding bladed attacks adopt a variety of complementary roles. These, that may include defending, communicating, first aid, recruiting others, marshalling, negotiating, risk assessment, and evidence gathering. Recommendations for practitioners and policymakers • Embed the psychology of public behaviour in emergencies in your training and guidance. • Continue to inform the public and promote public awareness where there is an increased threat. • Build long-term relations with the public to achieve trust and influence in emergency preparedness. • Use a unifying language and supportive forms of communication to enhance unity both within the crowd and between the crowd and the authorities. • Authorities and responders should take a reflexive approach to their responses to possible hostile threats, by reflecting upon how their actions might be perceived by the public and impact (positively and negatively) upon public behaviour. • To give emotional support, prioritize informative and actionable risk and crisis communication over emotional reassurances. • Provide first aid kits in transport infrastructures to enable some members of the public more effectively to act as zero responders.

STATEMENT OF THE NATIONAL ACADEMY OF EDUCATIONAL SCIENCES OF UKRAINE. National Academy of Educational Sciences of Ukraine, February 2022. http://dx.doi.org/10.37472/saveukraine.

Full text
Abstract:
We consider it criminal and strongly condemn the violation of the territorial integrity and borders of Ukraine by the Russian Federation. We also consider inadmissible the statements of the leadership of the Russian Federation regarding our state, interference in the internal affairs of Ukraine by denying its civilizational subjectivity and demanding the abandonment of its own path of development. With great gratitude and confidence in the victory, we turn to the defenders of Ukraine: we are together, we are convinced of the strength and steadfastness of those who defend Democracy, Freedom, and Human Values! Resistance is not just military resistance. The opposition of every citizen is not to succumb to provocations and panic, to prevent escalation of tensions, to refute fakes, to maintain clarity of thinking. A patriot is someone who invests in the development of the country and preserves its defense capabilities in a way accessible to him. For representatives of pedagogical and psychological sciences — is to maintain the national identity and unity of the nation at the level of consciousness of every citizen, territorial community, society. This is the strengthening of the subjectivity of every citizen through his awareness of Ukrainian history from the times of Kyivan Rus, Ukrainian mentality of freedom from the Cossack era, the spirit of Ukrainian democracy from the Constitution of Philip Orlyk, invincibility of the Ukrainian army from the victories of Peter Konashevych-Sahaidachnyi and Bohdan Khmelnytskyi, exercise of self-awareness by Hryhorii Skovoroda and Taras Shevchenko. Scientists of the National Academy of Educational Sciences of Ukraine, as always, are ready for a dialogue with anyone who finds himself in difficult life circumstances, in situations of confusion or uncertainty, who needs advice or psychological help. We all have hard work ahead of us every day. But our goal is common and high — to preserve the sovereignty and territorial integrity of Ukraine. To this end, we have worked for Ukraine′s independence, we have also worked for the development of our state for the last 30 years, for this, we are mobilizing for further struggle! We will win! Glory to Ukraine!
