The purpose of this paper is to explore the impact of augmented reality (AG) and the flipped learning model on the attitude of 4th-grade students towards the science and technology course and to determine the opinion of students concerning videos presented through AG. Another objective of the study is to determine parents' opinions concerning AG and FL in science and technology courses. A pre-test / post-test quasi-experimental design was used with the control group to obtain quantitative data. Qualitative data were also included in the analysis to support quantitative data obtained from a case study pattern. In the study, the Science and Technology Attitude Scale was used to measure students' attitudes. The Opinion Scale for Experimental Videos was used to evaluate video usage opinions in science and technology courses. Besides, parents' opinions concerning AG applications and the FL model were collected through the researchers' interview form. Independent sample t-test and ANCOVA tests were conducted to interpret the quantitative data of the study. Qualitative data were evaluated with the content analysis method. The results showed that the AR and FL model's application provides students with a positive attitude towards science and technology; it also helped them solve problems. Besides, families have also expressed positive opinions about AR and FL applications.

Full textAbstract:
While much has been published in anthropological discourse and teaching forums about the skills, practices and positionality of ethnographic writing, very little attention has been paid to the practices and experiences of ethnographic reading. Our project set out to investigate the potential for ‘slow reading’ within anthropological pedagogy. We invited anthropology undergraduates to select a book and engage in a period of slow reading over the vacation, before reporting back on their experiences through a focus group discussion. Students found that their ideals for slow reading were hard to realise, and we learned about the importance of appropriate spaces, times, and communities in practices of reading ethnography.

Full textAbstract:
Mind-body practices such as yoga and meditation are often believed to instill a “quiet ego,” entailing less self-enhancement. In two experiments, however, Gebauer et al. (2018) demonstrated that mind-body practices may actually increase self-enhancement, particularly because such practices become self-central bases for self-esteem. We conducted preregistered replications of both of Gebauer et al.’s experiments. Experiment 1 was a field study of Canadian yoga students ( N = 97), and Experiment 2 was a multiwave meditation intervention among Canadian university students ( N = 300). Our results supported Gebauer et al.’s original conclusions that mind-body practices increase self-enhancement. Although the self-centrality effects were not clearly replicated in either experiment, we found evidence that measurement and sampling differences may explain this discrepancy. Moreover, an integrative data analysis of the original and the replication data strongly supported all of Gebauer et al.’s conclusions. In short, we provide new evidence against the ego-quieting perspective and in support of the self-centrality interpretation of mind-body practices.

Full textAbstract:
The impact of urban experimentation on urban planning approaches is so far insufficiently assessed and discussed. This thematic issue sets out to investigate the possibilities and limitations of ‘urban planning by experiment,’ defined as an approach that uses experimentation to innovate and improve urban planning instruments, approaches, and outcomes. It brings together eight contributions presenting original research on urban experimentation and its relation to urban planning. All contributions are empirically grounded in (illustrative) case studies, mostly from European cities. Here, we summarize and discuss the major findings across the eight contributions with respect to three key themes: the practices of urban experimentation, its outcomes, and its impacts on urban planning. We conclude that the practices of urban experimentation described in the contributions generated a wide variety of substantive and learning outcomes, which, according to the authors, represent worthwhile additions or alternatives to the current repertoire of approaches and instruments of urban planning. However, except for a single case, large-scale integration of experimentation in established approaches to urban planning was not observed, let alone a complete transformation of urban planning practices. An area for further research concerns the relation between the way urban experiments are organized and conducted, and their impact on urban planning.

Full textAbstract:
With recent developments in X-ray sources, instrumentation and data-analysis tools, time-resolved crystallographic experiments, which were originally the preserve of a few expert groups, are becoming simpler and can be carried out at more radiation sources, and are thus increasingly accessible to a growing user base. However, these experiments are just that: discrete experiments, not just `data collections'. As such, careful planning and consideration of potential pitfalls is required to enable a successful experiment. Here, some of the key factors that should be considered during the planning and execution of a time-resolved structural study are outlined, with a particular focus on synchrotron-based experiments.

The Next Generation Science Standards (NGSS) were proposed in 2013 in the United States for K–12 learning to emphasize the importance of science and engineering practices in the three dimensions of science learning. In this study, we show that DNA extraction experiments, which are familiar in the United States, can be used not only as demonstration experiments but also as educational material for science practices. We could visualize extracted DNA using an enzyme treatment with DNase and RNase and agarose gel electrophoresis. We conducted a science practice in which a DNA extraction experiment was used as an extracurricular club activity in Japan. The students made predictions, conducted experiments, obtained results, and reflected on their findings. Although there are still points needing improvement, our results indicate that the DNA extraction experiment can be used as a new teaching material for NGSS science practices.

Full textAbstract:
Artificial weather modification experiments have been intensively practiced in many years over China, and some progresses have been made, including more methodologies and advanced instruments. However, a challenge question still remains for providing convincing scientific evidence during these practices and experiments. This is a very difficult scientific issue, which is related to complicated cloud physical science, such as to accurately predict the large natural variability of cloud formation and precipitation. In this study, we report a clear evidence that the cloud water is reduced after spreading diatomite particles in stratus clouds during a field experiment in Beijing, China. The analysis shows that the diatomite particles (15–20 μm in radius) are large and have strong hygroscopic property (absorbing cloud water). As a result, during the experiment, spreading large diatomite particles lead to downward motion (producing more stable atmospheric condition) and reduction of cloud water. It is noted that due to lacks of instruments, this designed experiment only can provide a qualitative result (such as photo evidence), and no quantitative result can be drawn from this experiment.

Full textAbstract:
Establishment of switchgrass (Panicum virgatum L.) is challenging, and failure in establishment may expose growers to considerable economic risk. The objectives of this research were to (i) evaluate whether management practices are variety-specific for the establishment of switchgrass and (ii) assess the effectiveness of cover crops as preceding crops on ‘Shawnee’ switchgrass establishment. Therefore, two studies were conducted at the University of Massachusetts Agricultural Experiment Station in Deerfield, MA, USA, in the 2011–2012 and 2012–2013 growing seasons. In Experiment 1, cover crop treatments (fallow, oat (Avena sativa L.) and rye (Secale cereale L.)) were the main plots, the two seeding methods (no-till drill and a cultipacker seeder (Brillion)) were the sub-plots, and the two varieties (‘Cave-in-Rock’ (CIR) and Shawnee)) were the sub-sub-plots. The second study was conducted using Shawnee switchgrass and involved the three cover crop treatments used in Experiment 1 using a cultipacker seeder with seed firming prior to planting but not afterwards (consistent in both experiments). The results indicated that a combination of oat and no-till resulted in higher tiller density (493%), lower weed biomass (77%), increased switchgrass biomass (SGB) (283%) and SGB to weed biomass (WB) ratio. Compared with Shawnee, CIR planted into a winter-killed oat residue had higher tiller density (93%), lower weed biomass (18%), higher switchgrass yield (128%) and thus a greater SGB:WB ratio (507%). Trends of switchgrass response to management practices, however, were similar between the two varieties, indicating that seed quality rather than management practices could influence switchgrass’s response to management practices. In Experiment 2, Shawnee tiller density was suppressed by rye as the preceding crop, possibly due to late termination of rye. Shawnee switchgrass yields were below 1000 kg ha−1 under all management practices; thus, harvesting should happen in the year following establishment. Future research should focus on comparing no-till drilling with cultipacker seeder with rolling not only before but after seeding to increase seed–soil contact.

Full textAbstract:
This paper argues that an important type of experiment-target inference, extrapolating causal effects, requires models to be successful. Focusing on extrapolation in Evidence-Based Policy, it is argued that extrapolation should be understood not as an inference from an experiment to a target directly, but as a hybrid inference that involves experiments and models. A general framework, METI, is proposed to capture this role of models, and several benefits are outlined: (1) METI highlights epistemically significant interactions between experiments and models, (2) reconciles some differences among existing accounts of experiment-target relationships, and (3) facilitates critical appraisal of inferential practices from experiments.

Full textAbstract:
Weed populations, weed control with imazethapyr, andGlycine maxyields were affected by a 4-yr history of different weed control practices. A range of chemical and mechanical practices were applied in separate field experiments initiated under high and low weed densities. In the high-density experiment, plots kept weed free for 4 yr averaged 24Setaria faberiplants m−2compared with 200 to 600 plants m−2with the various weed control treatments. In plots with a history of mechanical control, weeds not controlled by imazethapyr reducedG. maxyield by 340 kg ha−1compared with plots that were kept weed free during the same period. In the low-density experiment, weed control history had less effect on weed densities. For example,S. faberidensities ranged from 19 plants m−2for the weed-free plots to 195 plants m−2with mechanical control. Weed control history had little effect on weed control with imazethapyr orG. maxyields in imazethapyr-treated plots. While weed-free conditions for 4 yr greatly reduced weed densities, imazethapyr application still increasedG. maxyields 22% in the low-density experiment and 51% in the high-density experiment. Differences in densities of individual annual broadleaf species also developed in response to weed control history in both experiments.

Full textAbstract:
Background Ecological momentary assessment (EMA) is a measurement methodology that involves the repeated collection of real-time data on participants’ behavior and experience in their natural environment. While EMA allows researchers to gain valuable insights into dynamic behavioral processes, the need for frequent self-reporting can be burdensome and disruptive. Compliance with EMA protocols is important for accurate, unbiased sampling; yet, there is no “gold standard” for EMA study design to promote compliance. Objective The purpose of this study was to use a factorial design to identify optimal study design factors, or combinations of factors, for achieving the highest completion rates for smartphone-based EMAs. Methods Participants recruited from across the United States were randomized to 1 of 2 levels on each of 5 design factors in a 2×2×2×2×2 design (32 conditions): factor 1—number of questions per EMA survey (15 vs 25); factor 2—number of EMAs per day (2 vs 4); factor 3—EMA prompting schedule (random vs fixed times); factor 4—payment type (US $1 paid per EMA vs payment based on the percentage of EMAs completed); and factor 5—EMA response scale type (ie, slider-type response scale vs Likert-type response scale; this is the only within-person factor; each participant was randomized to complete slider- or Likert-type questions for the first 14 days or second 14 days of the study period). All participants were asked to complete prompted EMAs for 28 days. The effect of each factor on EMA completion was examined, as well as the effects of factor interactions on EMA completion. Finally, relations between demographic and socioenvironmental factors and EMA completion were examined. Results Participants (N=411) were aged 48.4 (SD 12.1) years; 75.7% (311/411) were female, 72.5% (298/411) were White, 18.0% (74/411) were Black or African American, 2.7% (11/411) were Asian, 1.5% (6/411) were American Indian or Alaska Native, 5.4% (22/411) belonged to more than one race, and 9.6% (38/396) were Hispanic/Latino. On average, participants completed 83.8% (28,948/34,552) of scheduled EMAs, and 96.6% (397/411) of participants completed the follow-up survey. Results indicated that there were no significant main effects of the design factors on compliance and no significant interactions. Analyses also indicated that older adults, those without a history of substance use problems, and those without current depression tended to complete more EMAs than their counterparts. No other demographic or socioenvironmental factors were related to EMA completion rates. Finally, the app was well liked (ie, system usability scale score=82.7), and there was a statistically significant positive association between liking the app and EMA compliance. Conclusions Study results have broad implications for developing best practices guidelines for future studies that use EMA methodologies.

Full textAbstract:
The purpose of this article is to find out the peculiarities of the application of algorithmic methods of the artistic and scientific experiment in modern practices of visual art; to identify the role of algorithmic methods in creating new aesthetics, stylistics, and artistic language through art history analysis of the work of leading groups of contemporary art and design. The research methodology includes generalization, systematization, and comparison, which contribute to the identification of the leading algorithmic methods in modern art and project practices; art description and analysis of experimental art projects were used to identify the role and principles of application of algorithmic methods in the scientific and artistic experiment. The scientific novelty of the study is to determine the typology, possibilities, and prospects for the application of algorithmic methods in conducting artistic and scientific experiments in modern design. The study reveals the varieties of algorithmic methods and, with the help of art history analysis, their role in the creation of “new aesthetics” and digital images in intersectoral art and design experiments; description of the technology and principles of application of parametrism as a promising stylistic and linguistic direction for the development of visual art and design. Conclusions. Algorithmic methods are actively used in scientific and artistic experimental practices of modern visual art. They create a “new aesthetic” through a variety of digital images and principles of parametric modelling. Algorithmic methods are based on mathematically generalized and reproducible laws of nature, which determine their application in the practices of biodesign and biomorphism. The review of modern art and design practice shows the growing interest in the new artistic stylistics and the use of algorithmic methods in the experimental creative work, which makes research in this area relevant and promising.

Full textAbstract:
There is increasing interest in experiments where outcomes are measured by surveys and treatments are delivered by a separate mechanism in the real world, such as by mailers, door-to-door canvasses, phone calls, or online ads. However, common designs for such experiments are often prohibitively expensive, vulnerable to bias, and raise ethical concerns. We show how four methodological practices currently uncommon in such experiments have previously undocumented complementarities that can dramatically relax these constraints when at least two are used in combination: (1) online surveys recruited from a defined sampling frame (2) with at least one baseline wave prior to treatment (3) with multiple items combined into an index to measure outcomes and, (4) when possible, a placebo control. We provide a general and extensible framework that allows researchers to determine the most efficient mix of these practices in diverse applications. Two studies then examine how these practices perform empirically. First, we examine the representativeness of online panel respondents recruited from a defined sampling frame and find that their representativeness compares favorably to phone panel respondents. Second, an original experiment successfully implements all four practices in the context of a door-to-door canvassing experiment. We conclude discussing potential extensions.

The notion of prioritising ‘productive’ social investments over ‘consumptive’ social spending has long been advocated but only sporadically applied. Since 2011, however, New Zealand governments have implemented an ambitious, multi-agency social investment agenda that promises to overhaul public social spending through analyses of citizen-derived data. This commentary focuses on the development and features of the social investment agenda. In doing so, it discusses the apparent primacy of fiscal outcomes over social outcomes, and the practices and politics of data-driven governance.

Abstract This paper explores the author’s experiences with divination practices and master-disciple relationships in Taiwan. The author discusses his interactions with various masters and Daoist priests and the debates and conversations that ensued. He also reflects on the positive and negative aspects of the master-disciple relationship, the importance of not being engulfed in such relationships, and the scientific and personal challenges he faced as he immersed himself in his object of study. Additionally, the paper provides insights into contemporary practices of divination in Taiwan and China, including the use of social media platforms for these practices. Overall, the study provides a unique perspective on the intersection of spirituality, divinatory culture, and technology in modern-day Taiwan, as perceived by both the subjective self and the observing eye of the scientist.

As planners and decision-makers experiment with information and communication technologies (ICTs), it’s important to explore and analyze these attempts in different planning systems and contexts. The aim of the article is to compare the use of and aspirations attached to e-planning in Helsinki, Finland and Sydney, Australia. This comparison will highlight the interrelationship between planning context and its amenability to an e-planning approach and shows there are shared themes in both cases: firstly, the complexity involved in reconciling the aims of the e-planning experiments and their connection to the planning process itself (roles, objectives, implementation of tools and processes). Secondly, the way that e-planning opens up cracks in the façade of administration, and thirdly, the ways in which e-planning provides possibilities to reshape existing planning procedures. The authors argue that the different planning and governance contexts affect the adoption of e-planning and this adoption is necessarily a selective process.

Full textAbstract:
The aim of this research is to introduce innovative cultivation practices that result in reduced nitrate levels in baby leaf lettuce grown under vertical farming conditions while maintaining high productivity. For this reason, three experiments were conducted. The first experiment focused on the impact of two “white” light spectra with a blue:green:red:far-red ratio of 14:32:43:10 (BlowRhigh) and 21:34:36:7 (BhighRlow). The second experiment assessed the effects of two nitrogen supply conditions: sufficient total nitrogen (N15) and limited total nitrogen (N5), and foliar biostimulant application. In the third experiment, the impact of replacing the nutrient solution in the N15 treatment with tap water for an additional 24 h (TW24) on leaf nitrate content was examined. Results from the lighting experiment revealed no significant effects on agronomical parameters or nitrate content between the two light spectra. Reducing nitrogen content in the nutrient solution reduced leaf nitrate content but negatively influenced agronomical characteristics. Biostimulant application and replacing the nutrient solution with water reduced leaf nitrate content compared to the control and positively affected growth. The most favorable outcomes were observed in plants supplied with sufficient nitrogen and foliar biostimulant but also cultivated for an additional 24 h with tap water (Sp-N15-TW24).

Drawing on social exchange theory, this paper analyzes the mediating role of responsibility for change and the moderating role of resource availability. Design/methodology/approach The authors conducted a scenario experiment using a sample of 329 part-time MBA students from various Chinese companies in Southwest China, using analysis of variance and regression to examine the hypotheses. Findings The results find a positive relationship between developmental HR practices and management innovation and responsibility for change mediates this relationship. Moreover, it examines the moderating role of resource availability. Resource availability positively moderates the correlation between responsibility for change and management innovation and moderates the mediation effect of responsibility for change on the correlation between developmental HR practices and management innovation. Practical implications Organizations should enhance the actual use of developmental HR practices to ensure the provision of appropriate training and development opportunities for all levels of employees in a fair and equal environment. It is better to take up an individual approach when offering these practices. Organizations should provide enough resources for employees, such as financial, spatial and temporal, and ensure the fair distribution of these resources. Organizations should cultivate the responsibility for change of middle-senior managers who can serve as role models for subordinates. Originality/value This study broadens the research on developmental HR practices, confirming that it has a positive impact on management innovation. It also provides more insight into the “black box” of developmental HR practices affecting management innovation, namely, the mediating effect of responsibility for change. This study shows that resources are critical to understanding how developmental HR practices can contribute to management innovation through responsibility for change. Using social exchange theory, the research deduces the conditional indirect effect of the model and uses a scenario experiment method to conclude causality.

In a three-year experiment, three types of soil conservation techniques were tested in the legumes cultivation systems. Our treatment types were no-till, standard tillage to the depth of 8 cm and deep tillage to 20 cm. The study evaluated winter pea (cv. Enduro), spring pea (cv. Eso), white lupine (cv. Amiga), narrow-leaved lupine (cv. Boregine) and soybean (cv. Merlin) in two autumn terms (winter pea only) and in spring term (all legume species). In no-till technology, the average yield of all legumes was 2.24 t/ha. For standard tillage (2.58 t/ha) and deep tillage (2.62 t/ha), yields were significantly higher than in no-till technology. From the monitored parameters, deep tillage appeared as the best soil treatment. Although the yield was similar to standard tillage, the soil was less stiffened, resulting in a higher content of nitrogen in the seed and a better use of the pre-crop value of the legumes. In the experiment, winter pea spring sowing term (2.93 t/ha) was better than both autumn sowings (2.68 t/ha and 2.65 t/ha).

In the years 2016–2018, two field experiments with species Sida hermaphrodita L. Rusby named Virginia fanpetals (syn. Virginia mallow) later in the manuscript as Sida, were carried out in the Świętokrzyskie province. They were located on light soil prone to drought. The experiments were established in a set of randomized blocks in triplicate. The results were statistically analyzed and significance of differences was assessed by Tukey’s test. In the first experiment, the influence of sowing dates (beginning, half, end of May) and fertilization before sowing (NPK: 20, 20, 40 kg∙ha–1 and control without fertilization) on the development of plants in the first growing year, were examined. In the second experiment, development and yielding of Sida after using three different propagation materials (seedling, root cuttings and seed sowing) in the first three years of cultivation, were compared. The test results clearly showed beneficial effect of pre-sowing fertilization compared to the control (without fertilization). From three May sowing dates, in three years on average, sowing in the middle of this month turned out to be the best. On the light soil prone to drought, the best conditions for growth and yield were provided by seedling and root cuttings, the least favorable – sowing seeds. The average heat of combustion was determined as 18.515 MJ∙kg–1.

Full textAbstract:
This essay takes the October Revolution's centennial as an occasion to consider Soviet state practices in an international context. Many features of Soviet governance reflected an interventionist ethos that first arose in western Europe and subsequently informed programs of population management around the world. From this perspective, we see that Soviet methods of rule derived not from socialist ideology but rather from pre-existing state practices. Communist Party leaders used these practices to pursue ideological goals, but both ambitions to reshape society and the means to do so originated elsewhere. This comparative approach also highlights ways the Soviet case resembled that of other late-developing countries, where educated elites similarly relied on state interventions to transform their populations. For many of them, the Soviet Union offered an alternative model of socioeconomic advancement, albeit one based on extreme state violence.

Abstract The cinematic double feature Grindhouse (2007) both celebrates cinematic history and typifies post-theatrical distribution practices. The film thematizes this paradox in the aesthetic tension between its two features, Planet Tenor and Death Proof, but each movie also offers a unique reinterpretation of its exploitation genre.

This research used the Research and Development (R&D) methodology, which has research steps in the form of R1D1...R2D2...RiDi to get an educational innovation called “Online Self-Training Program to Development for Teacher’s 21st-Century Skills Enhancement into Effective Practices” that is effective. It is an educational innovation with certified research results that can be used and disseminated to benefit development in schools that are the target population on a large scale. The online self–training program consisted of 2 projects: 1) Development Project for Teachers’ Learning with six self-training modules used to develop teachers; and 2) The Project for Teachers to Bring Learning Outcomes into Practice with Students with one self-training module to be used as a guideline for teachers. The results of the experimental research in the first project revealed that among the experimental group of 17 teachers, the learning outcomes had met the standard of the 90/90 criteria. Moreover, the average test scores after the experiment had been significantly higher than before the experiment, according to statistical analysis. In the experimental research of the second project, it was found that among the 510 students involved in the experiment, the average scores from the assessment of perception towards teachers' practices had been significantly higher after the experiment compared to before the experiment. It was found that the research results aligned with the pre-determined research hypotheses, indicating the effectiveness of educational innovations resulting from the research. These findings can be utilized to enhance and cultivate 21st-century skills for teachers in the targeted schools, demonstrating the potential for future research dissemination and application.

Full textAbstract:
Weed control practices affected the weed seed content of the soil, weed seedling populations, and corn and soybean yields in two 4-yr field experiments. When the initial weed seed density was high, giant foxtail seed numbers in soil declined rapidly under weed-free conditions. Changes in seed densities when initial densities were low varied over years. Mechanical and chemical control treatments had variable effects on weed seed numbers over the course of the experiment. Weed seed numbers and weed densities were sometimes greater if herbicides were banded, but crop yields were similar to full-rate herbicides in both experiments in all years. When the initial density was low, giant foxtail seed numbers in soil increased over the course of the experiment regardless of the weed control treatment. Seed densities of broadleaf species decreased under the same conditions. Also, when initial weed densities were low, weed control and crop yields were less sensitive to weed control practices than at high weed densities. Weather factors that influenced treatment efficacy had a major affect on weed populations and crop yield responses to the weed control treatments over years. The interactions of weed control practices, weed populations, and crop yields were complex. Initial weed density and species composition interacted with weed control treatments and weather patterns to generate the results observed.

Full textAbstract:
The objective of this research was to analyze the effect of immediate feedback on the detection and recognition memory of false and true news, using the Signal Detection Theory. For this, two experiments were carried out; in experiment one no feedback was presented; in experiment 2 immediate feedback was included. The experiments were divided into 2 phases: discrimination and news recognition memory. It included the participation of 93 young people, who judged the veracity or falsity of the news using a forced choice task, in 24 news with two types of attributes, physical and non-physical. The results indicated in experiment one, that the non-physical attributes alter the detection and memory recognition of the news, making the physical attribute of the font color irrelevant. In experiment 2, immediate feedback was found to improve detection, but not recognition, which is impaired by non-physical attributes as in experiment one. These findings show the need to present news readers with different sources of immediate verification to improve their detection, as well as the need to generate good information verification practices in the communication sector.

The adoption of Climate Smart Agriculture (CSA) practices could help smallholder farmers in Ethiopia enhance food security and appropriately manage climate change impacts. Conservation agricultural practice is intended to conserve, improve and make more efficient use of natural resources. However, despite these potential benefits, CSA is only practiced in some areas of Ethiopia and has not been sufficiently adopted by smallholder farmers. Therefore, this experiment was intended to improve the production and productivity of maize through different moisture conservation practices and to determine and recommend the best moisture conservation practices for agro-pastoralists in Yabello District, Borana Zone. The field experiment was conducted at Qobo, Qadale and Colksa Kebeles of Yabello districts for two consecutive years, from 2019 to 2020, the main cropping seasons. The experiments had four treatments (Runoff diversion, Furrow, Runoff diversion plus Furrow and Control) laid out in a randomized complete block design (RCBD) of three replications. The analysis of variance showed that there was a significant difference among treatments in days to maturity, cob diameter, cob length, hundred seed weight and grain yield in all cropping seasons and locations. The highest grain yield was obtained from furrow with diversion structure treatment (5.83, 5.59, 4.2 t/ha), followed by diversion structure (5.51, 4.84, 3.9 t/ha) at Qadale, Colkasa and Qobo Kebeles, respectively. The lowest grain yield was recorded for the control (farmers practice) treatment (3.56, 3.05 and 3.36 ton/ha) at Qadale, Colkasa and Qobo Kebeles, respectively. In all sites, moisture conservation treatments (furrow plus diversion, diversion and furrow) have yield advantages of 2.27 t/ha (40.68%), 2.54 t/ha (45.44%), 0.84 t/ha (20%), 1.95 t/ha (35.39%), 1.79 t/ha (36.98%), 0.54 t/ha (13.84%) and 1.88 t/ha (34.55%), 2.02 t/ha (39.84%) and 0.36 t/ha (9.43%) more than farmer’s practices, respectively. Therefore, moisture conservation practices are recommended for optimum production of maize in moisture stress areas of Yabello District, Borana Zone.

Full textAbstract:
The fate of 15N-labelled fertilizer applied to rice (Oryza sativa L) was studied in microplots established within two field experiments comprising a range of stubble levels, stubble management techniques, N application rates and times. The first experiment investigated uptake of soil and fertilizer N in plots where application of 0 or 100 kg N ha-1 to the previous rice crop had produced 11.5 and 16.1 t ha-1 of stubble respectively. The stubble was then treated in one of four ways-burn (no till); burn then cultivated; incorporated in autumn or incorporated at sawing. Microplots within these large plots received 60 kg ha-1 of 5% 15N enriched urea at sowing, just prior to permanent flood (PF), or just after panicle initiation (PI) of the second crop. The second experiment was undertaken within a field in which half of the plots had stubble from the previous three rice crops burned, while the other plots had all stubble incorporated. In the fourth successive rice crop, the two stubble management systems were factorially combined with three N rates (0, 70 or 140 kg N ha-1) and three application times (PF, PI or a 50 : 50 split between PF and PI). Nitrogen uptake and retention in the soil were studied within 15N-labelled microplots established within each of these large plots. Only 4% of the 15N applied at sowing in the first experiment was recovered in the rice crop, while delaying N application to PF or PI increased this to an average of 20% and 44% respectively over the two experiments. The doubling of N application rate doubled fertilizer N uptake and also increased uptake of soil N at maturity by 12 kgN ha-1. Three years of stubble incorporation increased average uptake of fertilizer and soil N in the second experiment by 5 and 12 kg N ha-1 respectively. In both experiments, the soil was the major source of N, contributing 66-96% of total N uptake. On average, in the fourth crop, 20% of fertilizer N was in the grain, 12% in the straw and 3% in the roots, while 23% was located in the top 300 mm of soil. A further 3% was in the soil below 300 mm. The remaining 39% was lost, presumably by denitrification.

The contribution offers to the disciplinary debate on theories and practices of land-use planning the restitution of an ongoing research work to support the drafting of an unusual Landscape-Energy-Tourism Plan. Within this endeavor, on the one hand, the article gives an account of the review conducted on the national and international literature as well as on the few available practices, bringing out the elements present and the gaps, including conceptual ones, that need to be filled. On the other hand, starting from ongoing experimentation, the contribution focuses on first directions for an integrated and wide area plan that can offer itself as a possible reference on what planning should be practiced to better hold together landscape protection and enhancement with the necessary regulation of renewable energy facilities and the promotion of sustainable tourism development paths. In the frequent lack of adequate resources and technical expertise as well as sufficient bargaining power in the face of national or international energy managers or unscrupulous entrepreneurs who offer more than the available agricultural land is worth or produces, non-metropolitan territories have only the integrated and intermunicipal plan from their side (even though they don't know or care). While for planners is very difficult to address at the same time landscape protection and tourism development with the very strong request of land for the (sustainable) energy facilities.

Full textAbstract:
In the context of climate change, the agricultural sector offers a large number of mitigation possibilities through diverse practices, such as the reduction of pollutant inputs. However, most farmers do not adopt the mitigation practices recommended, including the reduction of nitrogen fertilization. At the same time, various uncertainties characterize agricultural production, so that the farmer’s risk and ambiguity preferences may be potential determinants to the adoption of mitigation practices. In this context, the objective of the article is to determine if the farmer’s risk and ambiguity preferences explain (or not) the fertilization decision. A questionnaire was submitted to French farmers to elicit risk and ambiguity preferences through lottery choices, and ask questions about fertilization. Two regressions were realized, the first to explain the total fertilization and the second to identify the determinants of the first fertilization application. The results reveal that respondents were mostly risk-averse and ambiguity-neutral. In addition, risk and ambiguity aversion impact fertilization practices through diverse drivers in opposite directions. Indeed, being risk-averse is associated with a lower level of total fertilization, whereas ambiguity aversion has a positive and significant impact on the level of fertilization at the first application. This last result highlights the need to reduce the uncertainty farmers face.

Full textAbstract:
Introduction: experimentation is a widely used method of cognition in all scientific spheres, especially in natural branches of human knowledge. Jurisprudence uses the concept of legal experiment which most often understood as a law-making experiment consisting of creation of an experimental legal norm and introducing it on some territory or in some sphere of public relations. However, the phenomenon of legal experiment should also cover a research experiment as a special juridical method of cognition. Purpose: to characterize the possibilities of using the method of legal experiment in civil law research. Methods: a dialectical approach being the leading one forms the methodological basis of the work, complimented by the general scientific methods of cognition as well as the legal-dogmatic method and the hermeneutical method of legal studies. Results: the distinction was made between law-making and legal research experiments, the scope and limits of application of each of them were demonstrated; the necessity was explained of differentiation between the legal experiment method and the real results obtained upon exercising it; the necessity was proved of differentiating between imaginary and real-life experiments, this allowing to qualify only real-life experiment as a scientific research experiment constituting a special method of legal cognition. The main goals of the experiment in civil scientific works are testing the hypothesis and creating effective legal implementation practices.

Translational biomedical research relies on animal experiments and provides the underlying proof of practice for clinical trials, which places an increased duty of care on translational researchers to derive the maximum possible output from every experiment performed. The implementation of open science practices has the potential to initiate a change in research culture that could improve the transparency and quality of translational research in general, as well as increasing the audience and scientific reach of published research. However, open science has become a buzzword in the scientific community that can often miss mark when it comes to practical implementation. In this Essay, we provide a guide to open science practices that can be applied throughout the research process, from study design, through data collection and analysis, to publication and dissemination, to help scientists improve the transparency and quality of their work. As open science practices continue to evolve, we also provide an online toolbox of resources that we will update continually.

A before-after-only health education experiment was conducted by a team of a dozen health educators, nurses, and physicians who were students and faculty of the National Institute of Preventive and Social Medicine (NIPSOM). The experiment ran several months with 162 Moslem farming families in one village. Changes in sanitation-related knowledge, attitudes, and practices were measured and correlated with social class. It is suggested that the most useful sociology in the Third World is: (a) basic general sociological theory including ecosystem as well as social system, (b) multimethological including participant –observation, survey, and field experiment methods. Implications are drawn for graduate curricula in light of the trend toward increasing enrollments from Third World countries.

Full textAbstract:
Art is an integral, functional and impact model for the iterations of the artists, their creative intentions, self-cognition, and self-realization. Within this process, the artistic self-cognition is linked to the empiric experience, experiments, and searching for the new artistic methods ofrevealing the idea and context of the art object. Experimental modeling and implementation of innovations define the direction of changes in art that include the plot, form orimage, aesthetic reception, and general tendencies. On the turn of the 20th century, fundamental changes took place in the understanding of art. During this period, the range of art practices expanded essentially. Experimental spirit prevailed in the modernist practices; this fact prompted the genesis of new art systems and caused the heuristic process of understanding, interpretation, development, and functioning of art. The art principles and approaches of the postmodern era were characterized with the variety of multiple interpretations of the phenomena of past and present. By the means of experiment, the artists widened the boundaries of art, appealed to the new technologies, used different media ortheir synthesis that eventually caused the annihilation of the type specifics of the art objects. The aim of the article is to investigate the new approaches to modeling the experiments in Ukrainian painting of the late 20th and early 21st centuries as the implementation of innovations. The research methodology is based on the systemic, structural and functional, comparative and historical, and hermeneutic methods
