Abstract The objective of the study was to define the main opportunities and challenges for the commercialization of the new hulless barley variety ‘Kornelija’ arising from its biochemical and farming profile, and to present the evaluation for the approach to a new high protein-based payment system. Unlike the agricultural profile with both advantages and disadvantages, the variety shows distinctive grain quality and biochemical properties. Although there is a growing demand for high-nutrition and plant-based protein foods, farmers are focused on yield potential, not the nutritional value of cereals. By paying for the grains of ‘Kornelija’ the price that is equal or higher than winter wheat referenced break-even price, food processors would both motivate farmers to grow the variety and obtain grains with much higher protein content, and significantly higher β-glucans content than winter wheat to produce functional foods for a price that is close to the price of winter wheat.
摘要:本研究的目的是确定无壳大麦新品种“Kornelija”商业化的主要机遇和挑战,从其生化和耕作特征出发,并对新的高蛋白支付系统的方法进行评估。不同于既有优势又有劣势的农业品种,该品种表现出独特的粮食品质和生化特性。尽管对高营养和植物性蛋白质食品的需求不断增长,但农民关注的是产量潜力,而不是谷物的营养价值。通过为“Kornelija”谷物支付等于或高于冬小麦参考盈亏平衡价格的价格,食品加商既可以激励农民种植该品种,又可以获得蛋白质含量高得多的谷物,β-葡聚糖含量明显高于冬小麦,从而以接近冬小麦的价格生产功能食品。

Abstract A relevant and practical research object is analysed in the article – the implementation resolution of green transportation and the benefits of using such means. In this article, object is analysed from the interdisciplinary position, i.e. from the perspective of transportation, one of the logistical subsystems, and sustainable environment. The transportation department is undoubtedly an important guarantor of economic and industrial development. Despite the worldwide importance of transportation in everyday activities, the transportation also poses the risk for human health and life quality, for it is one of the biggest consumer of oil products and significantly contributes towards air pollution. Despite many theoretical and empirical researches, Šiauliai region still lacks an approach towards the implementation possibilities and studies revealing the benefits of green transportation. A comparative analysis has been performed by using the survey data, collected from 402 workers, responsible for transportation, working for Šiauliai regional companies. According to the results of the research for implementation situations of green transport in Šiauliai regional companies, the representatives of regional companies understand the importance of green transport, and more and more companies aim to reduce the environmental risk and to become more competitive. Integrated transportation by combining several means of transport, cargo consolidation by combining small orders and big orders, and ecological driving are the green transportation measures implemented most in regional companies. The typical benefits of green transport are increased environmental friendliness and improved relationship with consumers.
摘要:本文分析了一个相关的、实际的研究对象——绿色交通的实施方案和使用绿色交通的效益。本文从跨学科的角度,即从物流子系统之一的交通运输和可持续环境的角度进行分析。交通运输部门无疑是经济和工业发展的重要保障。尽管交通运输在日常活动中具有世界范围的重要性,但交通运输也对人类健康和生活质量构成风险,因为它是石油产品的最大消费者之一,并严重造成空气污染。尽管有许多理论和实证研究,Šiauliai地区仍然缺乏对绿色交通的实施可能性和研究的方法。通过使用调查数据进行了比较分析,收集了402名工人,负责运输,在Šiauliai地区公司工作。根据对Šiauliai区域公司绿色交通实施情况的研究结果,区域公司的代表认识到绿色交通的重要性,越来越多的公司以降低环境风险和提高竞争力为目标。多种运输方式相结合的综合运输、小单与大单相结合的货物集运、生态驾驶是区域企业实施最多的绿色运输措施。绿色交通的典型好处是增加环境友好性和改善与消费者的关系。

Abstract Climate change and environmental deterioration have been recognized as global drivers of change, and the shift to the “greener” economy is the key to sustainable development. The green economy is a priority field for developing and developed economies. However, as the authors of the publication have realised, there is no consensus about the meaning of the green economy and “green” jobs, that is why an uncertainty as in measurement of economic trends and an impact of it, as well as in what skills and competencies should be assigned to the “green” ones, arises. The new “green” processes and technologies are arising in a progressive trend, that is why it is important to ensure there are properly skilled candidates with appropriate “green” skills and competencies on the labour market, as well as to prepare fresh graduates with the “green” skills that will meet requirement of both, the recent and the future companies, especially operating in the “green” sector. In the framework of “SB Bridge” project an online survey was conducted by interviewing the “green” companies to identify which skills and competencies are needed for “green” jobs recently, and whether candidates and fresh graduates are enough with the “green” skills and competencies for fruitful engagement to “green” jobs. As the survey identified, fresh graduates and candidates for “green” jobs lack technical and (or) mechanical knowledge, IT skills, as well as experience and ability to work independently and in the team to resolve arising problems.
气候变化和环境恶化已被公认为全球变化的驱动因素,向“绿色”经济转型是实现可持续发展的关键。绿色经济是发展中经济体和发达经济体的优先领域。然而,正如该出版物的作者所意识到的那样,人们对绿色经济和“绿色”工作的含义并没有达成共识,这就是为什么在衡量经济趋势及其影响方面,以及在应该为“绿色”工作分配哪些技能和能力方面,出现了不确定性。新的“绿色”流程和技术正以一种渐进的趋势出现,这就是为什么确保劳动力市场上有具备适当“绿色”技能和能力的适当技能的候选人,以及培养具有“绿色”技能的应届毕业生,以满足当前和未来公司的要求,特别是在“绿色”领域的要求,这一点非常重要。在“SB Bridge”项目的框架内,我们通过采访“绿色”公司进行了一项在线调查,以确定最近“绿色”工作需要哪些技能和能力,以及候选人和应届毕业生是否具备“绿色”技能和能力,能够有效地从事“绿色”工作。调查发现,应届毕业生和“绿色”工作的候选人缺乏技术和(或)机械知识、资讯科技技能,以及独立工作和团队解决问题的经验和能力。

Abstract Social enterprises have positive effect on sustainable development, and they have become an important instrument for solving social problems (especially in rural areas), as the national and local governments alone cannot solve all such problems. To foster the development of social entrepreneurship, Latvia has introduced several support instruments for social enterprises, which include tax relief, privileged procurement contracts, grants, as well as non-monetary kinds of support. However, social entrepreneurs often point out that support from the national and local governments is insufficient, while the support instruments stipulated in the Social Enterprise Law are not widely used. Therefore, the aim of the research is to analyse national and local government support instruments for social enterprises in Latvia. The research found that the most important financial instrument fostering the development of social entrepreneurship in Latvia is a grant scheme administered by the Ministry of Welfare and the JSC Development Finance Institution Altum, which is available in the range of EUR 5000 to 200000 for investment and working capital. In the period 2017-2020, 94 social entrepreneurship projects with a total budget of EUR 6 million were supported, which could be viewed as significant financial support. In contrast, immovable property tax relief, exemption from enterprise income tax (on profits) and relief from this tax for several categories of non-business expenses are considered by social entrepreneurs to be an insignificant kind of support. There is also lack of experience and practice regarding the inclusion of social criteria in public procurement in Latvia.
社会企业对可持续发展具有积极的作用,已成为解决社会问题(特别是农村问题)的重要工具,仅靠国家和地方政府是无法解决所有社会问题的。为了促进社会企业的发展,拉脱维亚为社会企业引进了若干支助手段,其中包括税收减免、优惠采购合同、赠款以及非货币支助。然而,社会企业家经常指出,国家和地方政府的支持力度不够,《社会企业法》规定的支持手段也没有得到广泛应用。因此,本研究的目的是分析拉脱维亚国家和地方政府对社会企业的支持手段。研究发现,促进拉脱维亚社会企业发展的最重要的金融工具是由福利部和JSC发展金融机构Altum管理的赠款计划,该计划的投资和营运资金范围为5000至20万欧元。在2017-2020年期间,支持了94个社会创业项目,总预算为600万欧元,这可以被视为重要的财政支持。相比之下,减免不动产税、免征企业所得税(对利润)以及减免几类非经营性费用的企业所得税,社会企业家认为是一种微不足道的支持。拉脱维亚在将社会标准纳入公共采购方面也缺乏经验和做法。

Abstract To survive in today's competitive environment, companies must continuously develop and offer customers new products. To increase the probability of a successful business case of investing in the development of a new product, careful attention must be paid to risk analysis in terms of the present value of future potential income. The article considers an example of the research work of the Latvia University of Life Sciences and Technologies, in the framework of which a technical and technological project was developed to produce a new product, like Mediterranean anchovy, from cheaper Baltic sprats. The main goal of this work is to explore the application multi-factor sensitivity and fuzzy real option analysis to the valuation of new product development project. The multivariate analysis of the sensitivity of the financial model of the greenfield production project described in this article revealed the main risk groups, as well as their degree of influence on the assessment of the Net Present Value of the project by a potential investor. The use of Fuzzy Real Option Valuation made it possible to evaluate the project with uncertain parameters, as well as to calculate the potential upside from preliminary refinement of parameters to eliminate negative scenarios. The described approach is applicable to risk assessment of new food product development and allows investors to make a more informed decision about participation in such projects.
为了在当今竞争激烈的环境中生存,企业必须不断开发并为客户提供新产品。为了增加投资开发新产品的商业案例成功的概率,必须根据未来潜在收入的现值仔细注意风险分析。本文考虑了拉脱维亚生命科学和技术大学研究工作的一个例子,在该研究的框架内,制定了一个技术和技术项目,以生产一种新产品,如地中海凤尾鱼,用更便宜的波罗的海鱼。本文的主要目的是探讨多因素敏感性和模糊实物期权分析在新产品开发项目价值评估中的应用。本文所描述的绿地生产项目财务模型敏感性的多变量分析揭示了主要风险组,以及它们对潜在投资者评估项目净现值的影响程度。模糊实物期权估值的使用使得对具有不确定参数的项目进行评估成为可能,并通过对参数的初步细化来计算潜在的上行空间,以消除负面情况。所描述的方法适用于新食品开发的风险评估,并允许投资者对参与此类项目做出更明智的决定。

Abstract Feeding young animals is a very important stage during their growing-up period, but in order to provide them with essential nutrients, they are fed with liquid feeds, whole milk substitute in particular (WMS). The technique for reconstituting WMS consists of dissolving it in water followed by mixing, but it is significant to follow the cooking recipe strictly, so it is necessary to develop a system with a feeding (dosing) device that will make it possible to solve this problem. Theoretical and experimental studies of the feeding device have been conducted in order to optimize the technological process of mixing liquid feed. Theoretically, the quality of determining the mixture during dosing was established for the purpose of further research. The influence of the design and technological parameters of the feeding device was experimentally studied, and its efficiency was evaluated. It was found that as the inclination angle α increases from 67,50 to 700, the rotation speed n being from 850 to 1500 min−1, the maximum probability of staying in the tolerance field ΔP=96% is reached, and feed discharge Q ranges from 540 to 660 kg h−1. The research makes it possible to develop a feeding device at the design stage, meeting the requirements of the recipe, having high discharge rates and the lowest energy consumption.
摘要饲喂幼龄动物是幼龄动物成长过程中非常重要的一个阶段,为了给幼龄动物提供必需的营养物质,通常采用液体饲料,特别是全脂牛奶替代品(WMS)进行饲喂。重建WMS的技术是将其溶解在水中然后混合,但严格遵循烹饪配方是很重要的,因此有必要开发一种带有加料(加药)装置的系统,使其有可能解决这一问题。为了优化液体饲料混合工艺流程,对进料装置进行了理论和实验研究。理论上,为进一步的研究建立了在加药过程中确定混合物的质量。实验研究了进料装置的设计和工艺参数对进料装置的影响,并对其效率进行了评价。结果表明,当倾角α从67、50增加到700,转速n在850 ~ 1500 min−1范围内时,停留在公差场ΔP=96%的概率最大,给料量Q在540 ~ 660 kg h−1范围内。本研究使在设计阶段研制出满足配方要求、出料率高、能耗低的加料装置成为可能。

Abstract Fermentation is one of the ancient technological processes used in food production which influences the shelf-life of meat and meat products, also significantly affects the sensory properties like aroma and flavour. The objective of the present study was to evaluate the elaborated technology for a new fermented sausage production on the product quality and sensory properties. Sausages were produced by the standard technology using glucono-delta-lactone or starter culture. The drying of samples differs from 3 to 4 weeks at the same conditions; samples were dried for 4 weeks which produced with the starter culture, and 3 weeks which produced with glucono-delta-lactone. The sausages were tested at the end of the production, analysing pH, water activity, moisture and salt content, as well as the presence of Listeria monocytogenes, colony forming units of Listeria monocytogenes and Enterobacteriaceae in the sausage samples were analysed. The sensory evaluation was organised after getting Listeria monocytogenes testing results. The moisture content, water activity and salt content significantly differed (p < 0.05) among samples, no differences were established in pH, taste and flavour liking. The presence of Listeria monocytogenes was not established in samples which indicates that the producer properly applies a hurdle technology in fermented sausage production. Sensory evaluation results showed higher scores for texture and appearance in fermented sausages with glucono-delta-lactone. The study results confirmed that fermented sausages with glucono-delta-lactone during 3 weeks of drying can achieve corresponding safety criteria and sensory properties which are set for semidry fermented sausages.
摘要发酵是食品生产中使用的古老工艺之一,它影响肉和肉制品的保质期,也显著影响香气和风味等感官特性。本研究的目的是评估新型发酵香肠生产工艺对产品质量和感官特性的影响。香肠是通过使用葡萄糖酸-Δ内酯或发酵剂培养的标准技术生产的。在相同的条件下,样品的干燥时间从3到4周不等;样品用发酵剂培养物干燥4周,用葡萄糖酸-Δ内酯干燥3周。在生产结束时对香肠进行了测试,分析了pH值、水活度、水分和盐含量,以及香肠样品中是否存在单核细胞增多性李斯特菌、单核细胞增生性李斯特菌和肠杆菌科的菌落形成单位。感官评价是在得到单核细胞增多性李斯特菌检测结果后组织的。不同样品的水分含量、水分活度和含盐量存在显著差异(p<0.05),在pH、味道和风味方面没有差异。样品中没有确定单核细胞增多李斯特菌的存在,这表明生产商在发酵香肠生产中正确地应用了栅栏技术。感官评价结果显示,添加葡萄糖酸-Δ内酯的发酵香肠的质地和外观得分较高。研究结果证实,添加葡萄糖酸-Δ内酯的发酵香肠在干燥3周后可以达到半干发酵香肠的相应安全标准和感官特性。

The sausages were tested at the end of the production, analysing pH, water activity, moisture and salt content, as well as the presence of Listeria monocytogenes, colony forming units of Listeria monocytogenes and Enterobacteriaceae in the sausage samples were analysed. The sensory evaluation was organised after getting Listeria monocytogenes testing results. The moisture content, water activity and salt content significantly differed (p < 0.05) among samples, no differences were established in pH, taste and flavour liking. The presence of Listeria monocytogenes was not established in samples which indicates that the producer properly applies a hurdle technology in fermented sausage production. Sensory evaluation results showed higher scores for texture and appearance in fermented sausages with glucono-delta-lactone. The study results confirmed that fermented sausages with glucono-delta-lactone during 3 weeks of drying can achieve corresponding safety criteria and sensory properties which are set for semidry fermented sausages.","PeriodicalId":30922,"journal":{"name":"Rural Sustainability Research","volume":"45 1","pages":"1 - 6"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48641106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Information and communication technologies are part of almost any branch of human lives. During the last decade also beekeeping joined the direction of application of IT tools and solutions and precision beekeeping was defined. Still in the beekeeping many operations and observations are completed manually, and there is a potential to switch to the digital realisation. Information technologies can be used in the beekeeping to partly support the beekeepers by implementation of automatic or semi-automatic solutions for bee colony remote monitoring, apiary record making and other actions. The aim of this paper is to make a summary of the usage of information technology tools by the beekeepers in Latvia, summarizing precision beekeeping development status and conclude about its future development potential. To achieve this aim, in cooperation with Latvian Beekeepers Association, a beekeepers survey was conducted. More than 200 beekeepers shared thoughts and opinions about their application of information and communication technologies for monitoring the bee colonies and apiary management. The summary of the survey conducted is described in this study.
信息和通信技术几乎是人类生活的任何一个分支的一部分。在过去的十年中,养蜂业也加入了应用IT工具和解决方案的方向,并定义了精确养蜂。在养蜂业中,许多操作和观察仍然是手动完成的,并且有可能切换到数字实现。信息技术可用于养蜂,通过实施蜂群远程监测、养蜂记录制作等自动化或半自动解决方案,部分支持养蜂人。本文的目的是对拉脱维亚养蜂人使用信息技术工具的情况进行总结,总结精确养蜂的发展现状,并对其未来的发展潜力进行总结。为了实现这一目标,与拉脱维亚养蜂人协会合作,进行了养蜂人调查。200多名养蜂人分享了他们在蜂群监测和养蜂场管理中应用信息通信技术的想法和意见。本研究总结了所进行的调查。

Abstract It is stated that the strategic benchmark for transformational changes in the economy is currently low-carbon production, the achievement of which is possible to provide with the consistent application of an arsenal of strict control measures, in particular, the introduction of state audit of low-carbon production. The effectiveness of the mechanism for ensuring the implementation of the UN Framework Convention on Climate Change has been assessed. The necessity of implementation in the domestic practice of the state audit of low-carbon production by the decoupling approach is proved. The agri-business portfolio has been formed according to the decoupling approach as one of the leaders in greenhouse gas pollution. The author's economic and mathematical models of estimation according to the decoupling approach of the impact of branches of crop and livestock production on environmental pollution are proposed. The dependence of greenhouse gas emissions on the volume of gross output of agricultural production, capital investment and current expenditures on environmental protection has been established. The results of a comparative analysis of the realism of forecasts of changes in greenhouse gas emissions according to the methodology of the National Academy of Sciences of Ukraine and the author's methodology are highlighted. A roadmap for the introduction of a state low-carbon decoupling audit of the state decoupling audit has been proposed as part of the preparation of the second nationally determined contribution to the Paris Agreement. The expediency of supplementing GRI 300 “Environmental Disclosures” with the group of indicators GRI-305.5 “Reduction of GHG emissions”, formed by the decoupling approach, is substantiated.
摘要指出,当前经济转型的战略基准是低碳生产,实现这一目标可能需要持续实施一系列严格的控制措施,特别是引入对低碳生产的国家审计。已经评估了确保《联合国气候变化框架公约》执行的机制的有效性。论证了脱钩法在国内低碳生产国家审计实践中实施的必要性。农业企业组合是根据脱钩方法形成的,是温室气体污染的领导者之一。根据作物和畜牧业生产部门对环境污染影响的解耦方法,提出了估算的经济和数学模型。温室气体排放量对农业生产总产量、资本投资和环境保护经常支出的依赖性已经确立。重点介绍了根据乌克兰国家科学院的方法和作者的方法对温室气体排放变化预测的现实性进行比较分析的结果。作为对《巴黎协定》第二次国家自主贡献的准备工作的一部分,已经提出了引入国家低碳脱钩审计的路线图。用脱钩方法形成的一组指标GRI-305.5“减少温室气体排放”补充GRI 300“环境披露”的方便性得到了证实。

Abstract Reduced tillage is considered as one of the main tools to save biological diversity; however, it increases pressure of diseases, including wheat leaf blotches. The aim of present study was to clarify the impact of reduced soil tillage on the development of winter wheat leaf blotches in different schemes of crop rotation. The impact of different growing technologies on the severity of winter wheat disease was evaluated in a two-factorial experiment: A – soil tillage system, and B – different combinations of wheat pre-pre-crop and pre-crop (wheat, oilseed rape, barley and faba beans). Diseases were assessed every 10 days approximately and total impact of diseases was evaluated by calculating AUDPC (Area under Diseases Progress Curve). Tan spot, caused by Pyrenophora tritici-repentis was dominated disease over the long period, regardless of meteorological conditions. Development of Septoria leaf blotch was not influenced by neither crop rotation nor soil tillage. The level of tan spot was essentially higher after wheat, regardless of the pre-pre-crop. Reduced soil tillage promoted severity of tan spot. Ploughing mitigated effect of previous crops and differences in tan spot level were insignificant. Despite many positive effects of conservation tillage, increasing of fungicide treatment could be necessary, in conditions, when the tan spot is most devastating and widespread wheat disease.
摘要减少耕作被认为是保护生物多样性的主要工具之一;然而,它增加了包括小麦叶斑病在内的疾病的压力。本研究的目的是阐明在不同轮作方案下,减少土壤耕作对冬小麦叶斑发育的影响。在一项双因子实验中评估了不同种植技术对冬小麦病害严重程度的影响:a–土壤耕作制度,B–小麦孕前和孕前的不同组合(小麦、油菜、大麦和蚕豆)。大约每10天对疾病进行一次评估,并通过计算AUDPC(疾病进展曲线下面积)来评估疾病的总影响。无论气象条件如何,由小麦拟除虫菊引起的谭斑病在很长一段时间内都是主要病害。Septoria叶斑病的发生不受轮作和土壤耕作的影响。小麦后的棕褐色斑点水平基本上更高,而与作物前无关。减少土壤耕作可提高棕褐色斑点的严重程度。耕作减轻了以往作物的影响,棕褐色斑块水平差异不显著。尽管保护性耕作有许多积极影响,但在棕褐色斑点是最具破坏性和最广泛的小麦病害的条件下,增加杀菌剂处理可能是必要的。
