PurposeThe purpose of this study is to explore the impact of abusive supervision on employees' voice in China's construction industry. Moreover, the authors explore the mediating role of ethics-related self-efficacy and work engagement and the moderating influence of psychological climate in explaining the association between abusive supervision and employee voice behavior.Design/methodology/approachThis study used data in pairs collected from 402 supervisors and employees of construction companies in Anhui, China. In this study, the authors used the time-lag approach to collect data in three-time waves from different respondents. A structural equation modeling (SEM) approach was applied to test the hypothesized model.FindingsThe results of this study indicate that there is a significant association between abusive supervision and employee voice. Moreover, the results indicated that work engagement mediated the association between abusive supervision and employees' voice. In contrast, self-efficacy did not mediate the link between abusive supervision and employee voice. Furthermore, results also show that the contingent effect of psychological climate significantly influences the mediating effect of work engagement.Originality/valueThis study also has implications for the construction industry, allowing managers to create a favorable working atmosphere in which employees can reinforce their voices at work.

The use of mathematical modeling in various branches of the food industry as an effective tool for the policy of resource conservation of food systems is an innovative solution in the field of improving the efficiency of existing food production technologies based on established patterns in the production process. The issues of operational quality control in the process of processing food products with a stream of accelerated electrons in the absence of radiation doses regulated by standards, except for certain types of spices, to ensure the safety and quality of food products, in particular chilled fish, require a constructive approach with the general predictability of technological parameters in specialized radiation centers – operators of the irradiator. It was found that the dose absorbed by the samples of common carp scales with a high degree of correlation of 0.94 depends on the actual radiation dose and increases to 7.51±0.04 kGy when irradiated with a dose of 12 kGy or 25.9 times compared to samples treated with a stream of accelerated electrons with a radiation dose of 1 kGy. It is revealed that the operational quality is determined by the reproducibility of the results under the established conditions of the production processing process. As a result of experimental testing, mathematical models of various types were developed to predict the absorbed dose from experimental conditions on the example of samples of chilled carp scales: polynomial, 3D-graph and arccos. The practical significance is determined by the possibility of designing experimental conditions for processing chilled fish with a stream of accelerated electrons without performing trial processing of small batches of food products in radiation centers and using emitters as a model for technological runs.

Based on the theory of resource conservation, this study considers that inclusive human resource practices have an impact on individual innovation behavior, which is moderated by homesickness. In addition, this study clarifies that emotional exhaustion can exacerbate the destructive effects of homesickness. By collecting 292 sample data, the study found that inclusive human resource practices have a positive impact on individual innovation behavior, and homesickness moderates the impact of inclusive human resource practices on innovation behavior. When the level of homesickness is high, the impact of inclusive human resource practices on innovation behavior will be weakened. Emotional exhaustion moderates the moderating effect of homesickness. When the level of emotional exhaustion is high, the weakening effect of homesickness will be stronger. Based on this, this study provides theoretical and practical reference for the study of inclusive human resource practice, and further enriches the homesickness literature.

Globally, the role of extension agents in scaling up the utilization of Climate Smart Agricultural Initiatives (CSAI) by farmers remains very crucial. This study examined the determinants of the involvement of extension agents in the dissemination of CSAI to farmers. A two-staged random sampling technique was used to elicit information from 277 extension agents in South West Nigeria using a structured questionnaire. Data were analysed using frequency counts, percentage and linear regression analysis. The findings revealed that prominent initiatives extension agents disseminated were cover crops planting and minimum tillage practices. However, extension agents had low involvement in the dissemination of use of soil amendments, conversion of waste to compost, agro-forestry, resource conservation and use of agro-weather related initiatives Significant factors influencing extension agents’ involvement in the dissemination of CSAI are educational qualification (t = 2.57; p = 0.011), years of experience (t = 5.11; p = 0.000), participation in CSA training (t = 1.77; p = 0.077) and numbers of community covered (t = −2.30; p = 0.022). The study concludes that although extension agents are involved in the dissemination of some CSAI, there are still a wide range of initiatives that are not adequately disseminated to the rural farmer. It was therefore recommended that extension agents should be trained especially on the wide range of CSAI identified not to be predominantly disseminated so as to scale-up their adoption by farmers to enhance sustainable agricultural productivity and food security for all.

A field study was conducted during three consecutive years of 2016-17, 2017-18 and 2018-19 at university farm at Bihar Agricultural University, to assess the impact of resource conservation and nutrient management on yield, economics, and energetics of rice-wheat cropping system. The experiment was conducted in split plot design replicated thrice with three cropping system establishment methods viz. system of rice intensification + conventional wheat, transplanted rice + conventional wheat with 30% rice residue incorporation and direct seeded rice + zero tilled wheat with 30% rice residue incorporation as main plot and with three nutrient management practices viz. 100% of Recommended dose of fertilizer (RDF) through inorganic sources, 75% of RDF through inorganic sources + 25% of RDF through organic sources (vermicompost), 50% of RDF through inorganic sources + 50% of RDF through organic sources (vermicompost) and 100% of RDF through inorganic sources + mungbean as green manuring. It was obvious from the result that highest rice yield (48.7 qha-1) was from system of rice intensification + conventional wheat meanwhile highest wheat yield (47.0 qha-1) and system productivity (rice equivalent yield) (91.3 qha-1) was from direct seeded rice + zero tilled wheat with 30% rice residue incorporation. Moreover, the dominance of resource conservation practices on other practices was prevalent in the cropping system as highest B:C ratio (1.92) was obtained from direct seeded rice + zero tilled wheat with 30% rice residue incorporation. Lowest greenhouse gas emission i.e. CH4, CO2, N2O was from direct seeded rice with zero tilled wheat and residue incorporation at different stages of crop growth. Among different nutrient management practices highest yield both for rice (48.3qha-1) wheat (43.9qha-1) and rice equivalent yield (95.2 qha-1) was obtained from 100% of RDF through inorganic sources + mungbean as green manuring. Adding to this the B:C ratio was also least (1.84) from same, whereas lowest greenhouse gas emission (CH4, CO2) was from 100% inorganic fertilizers. And lowest nitrous oxide emission was from 50% inorganic and 50% organic fertilizers.

Актуальность исследования обусловлена необходимостью нефтегазодобывающему сектору проводить корректный прогноз добычных возможностей планируемых к бурению скважин как на разрабатываемых, так и на новых месторождениях, вводимых в промышленную эксплуатацию. Оценка достижимых дебитов при планировании стратегии разработки месторождения позволяет не только прогнозировать проектные уровни добычи, но и принять решение по совершенствованию стратегии запуска и разработки месторождений. Рациональное планирование снижает негативное влияние на окружающую среду и ведет к энерго- и ресурсосбережению, также минимизирует риски невыполнения плановых показателей, что является причиной постоянной корректировки объемов добычи в меньшую сторону, ускоряет запуск новых скважин, что повышает негативное влияние процесса бурения на окружающую среду, сокращает стандартное-рекомендованное время на мероприятия и снижает качество строительства скважин. Цель: оценка потенциала пласта в той или иной зоне при выборе размещения проектного фонда скважин перед бурением, приводящая к более рациональному планированию объемов добычи углеводородного сырья, которые определяются на основании расчетов гидродинамической модели. Объект: разрабатываемые и вводимые в промышленную эксплуатацию (новые) месторождения углеводородов. Методы: индивидуальный подход к каждой скважине при определении стартовых дебитов скважин на стадии проектирования разработки месторождения. Результаты. Разработана новая методика определения запускных дебитов проектных скважин, позволяющая более точно прогнозировать начальный дебит горизонтальной скважины в определенном районе на не введенном или уже разрабатываемом месторождении нефти, газа и газоконденсата. The relevance of research is caused by the necessity for oil and gas sector to make the correct forecast of production capabilities of the wells planned for drilling both at those being developed and the new ones which are being planned putting into commercial operation. Estimation of achievable production rates during planning a field development strategy allows not only evaluating the projected production level, but as well making a decision on improving the strategy for launching and developing fields. A sustainable planning reduces the negative impact on the environment and leads to energy and resource conservation. Moreover, it minimizes as well the risks of failure to achieve targets, which results in constant adjustment of production levels downwards, accelerating the launch of new wells, which increases the negative impact of drilling on the environment, reduces the standard-recommended time for activities and the quality of well construction. The main aim of the study is to assess the reservoir potential in a particular zone during selecting the location of the project fund of wells before drilling, leading to more sustainable planning of hydrocarbon production volumes determined based on calculations on the simulation model. Objects: hydrocarbon fields under development and those, putting into commercial operation (new). Methods: individual approach to each well during determination of the initial production rates of wells at the engineering design stage of a field development. Results. The authors have developed the new methodology for identifying the starting production rates of project wells, which allows more accurate prediction of the initial production rate of a horizontal well in a specific area in an unreleased or already developing oil, gas and gas condensate field.

Understanding the contributions of participants from management practices and those from the local community to protected areas (PAs) as nature reserves, is crucial for forest protection and resource conservation. Thus, empirical studies have usually investigated whether patrolling has significantly improved forest protection action. Many previous studies have exhaustively examined the contributions to forest protection by rangers or local persons, but there has been little research on the contribution of both sides to patrol efforts with separate consideration given to each. This paper explores insights into the patrol efforts in the Nam Tien forest station. The total number of patrollers, walking distances, and working days across years were significantly different between the ranger and local person patrol groups. There was a considerable variation in the number of patrollers (Z = 2.02; p < 0.01), distance (Z = 2.45; p < 0.01) and working days (Z = 2.37; p < 0.01) between rangers and local persons related to monthly patrolling. For the traditional patrols in the various PAs, it is shown that, for long-term forest protection, local persons patrolling should be considered more, in order to achieve the sustainable conservation.

Previous studies affirmed that both poverty and environmental resources degradation need to be tackled concomitantly. The reason is that poverty and environmental resources (agricultural land) are intertwining as a nexus; hence a one traffic-proffered solution is not sufficient enough to reduce the afterward menace poverty and environmental resource caused. An incentive that serves as an ‘adjudicator’, a credit-based payment for an environmental service is recognized for this task. Though this is a hypothetical case of Payment for Environmental Services (PES) that understudied the would-be response of the poor farming household through their preferences of PES attributes of environmental resource conservation and poverty reduction. This was designed with the use of choice experiment method, which is a multi-attribute approach of valuing non-market goods (agricultural land). Evidently, this study has convincingly proved that the poor farmers are willing to conserve their agricultural land, if the provision of necessary incentive is presented to them. The examined three farm settlements in Oyo state are: Afijio, Ijaye and Ido farm settlements. Educationally poor farming household shows that, 93(65.49%) preferred both options, whereas consumption poor farming house have 162(68.5%) respondents that sought for both option 1and 2.Housing/standard of living farming household recorded 98(34.63 %) for option 1 PES attributes and 95(33.57%)responded were for option 2 of PES attributes. The T-t test revealed that four of the paired poverty categories with respect to their preferences for the PES attributes options were significant. This study therefore suggests that poor farming household, whose farming is their livelihood should be sensitized to the provision of a deliberately designed poverty-environmental resource conservation credit-based PES, with a more flexible conditions. This will enable the poor farmers to be encouraged to participate in conservation of natural resource and by extension reducing poverty.

Schools are accountable to cultivate environmental awareness and participation among future leaders. In an attempt to address this concern, this research determined the level of environmental awareness and involvement of teacher education seniors in one state university in the Philippines. Specifically, it focused on the respondents' level of environmental awareness in terms of issues and policies and level of environmental participation in terms of waste management, resource conservation, and environmental initiative. By employing the descriptive method of research with self-made questionnaire as its gathering tool. This paper found out that the respondents were unaware of environmental issues and policies, while they were moderately participative in activities relevant to environmental protection and conservation. With the findings of the study, enrichment activities offered by the researcher as well as considered by concerned authorities for its maximum actualization to enliven the once-perfect the environment which human beings continuously destroy.

The results show that humble leadership hasa positive influence on employeecreativity, and this relationship is mediated byknowledge hiding.Perceived organizational support positively moderates the relationship between humble leadership and employee creativity

This paper traces past and present entanglements between people and elephants along a forest-agriculture fringe in Kerala's Western Ghats. In doing so, it explores the evolution of conservation-linked conflict and its problematic impacts. Over the centuries, the region's elephants have played a dominant role in its mountain landscapes: as antagonists to cultivators; as sources of ivory, labour and revenue to forest traders, local rulers and imperial administrators; and as cultural and religious icons straddling forests and countryside. Environmental protection arrangements in recent years ushered in a new elephant, a charismatic flagship beloved of conservationists, but also a key actor involved in fluctuating tensions along the forest edge. In this study, I explore long-term engagements between people and elephants by interrogating three critical phases in history, each incorporating a changing identity for the place in question: as a bountiful, ivory-rich forest at the turn of the Christian Era; as a site of capitalist production during the colonial period; and eventually as a contested conservation landscape. I show that these identities are predicated as much by extra-local processes such as migration and capitalist enterprises, as by embedded engagements with non-human agency. Contemporary conflict is, therefore, a complex ongoing narrative fuelled by a dynamic interaction between the persistence of human and animal memories as well as by multi-scale socio-political catalysts with long histories of influence. By ignoring historical contingencies and diverse discourses, contemporary conservation interventions may overlook the proverbial and sometimes literal elephant in the room.

Recycling of materials is one way to achieve resource conservation, which could be implemented in new technology to sustain its development. We organize this review to raise awareness of the applications of photoluminescent carbon nanodots (C-dots) to food safety, with an emphasis on C-dots synthesized from food or food wastes. The diverse chemical constituents in agriculture and food products, including wastes, provide a multitude of carbon precursors for C-dots. Some of these C-dots have been developed to function as sensors for food-borne pathogens, heavy metals, and harmful colorants in food products. This process of using food and its byproducts to improve food safety is one step forward in the way of conservation and industry self-efficiency.

Tagal is the local knowledge that been implemented by Sabahan people in Sabah. The conservation can be apply in various way to conserve many thing and it became a one of the community movement strategic to make the world be a better place for our next generation. In Sabah, tagal has been used widely with the first movement is to conserve fish through the river. This movement was accepted and become one of the tourism attraction and give economic benefit to local community.

Different psychological stress models focus on the role of resources in the process of stress development. In Chap. 6 we present two such models: the job demands-resources model and conservation of resources theory. These models explain how resources counteract strain, promote engagement and motivation, and influence whether a stressor is actually perceived or evaluated negatively or whether it is considered a challenge to be mastered. People can actively build and acquire new resources or maintain and preserve existing resources. Positive emotions play an important process in building resources.

Ecological civilization construction has become an important part of national development. We must establish and practice the idea that clear water and green mountains are mountains of gold and silver, adhere to the basic state policy of resource conservation and environmental protection, form a green way of development and a way of life, firmly follow the path of civilized development with production development, a prosperous life and a sound ecology, and build a beautiful China. This article introduces the practice of green highway construction in Jiangxi Province from the connotation of green highway, promotion of green technology application, green construction technology and innovative management. Finally, the future development direction of green highway in Jiangxi province is prospected.

Forests provide valuable ecosystem services to individuals that live near them and visit them. However, many forests, especially in highly developed areas, are specifically managed for resource conservation purposes. A common practice for conservation is restricting access to people to ensure minimal human-driven harm. While the restriction of human access to a forest increases its biological ecosystem services, it limits its cultural services and may reduce the public&rsquo, s perceived value of the forest. To investigate how access influences the perceived value of a forest, two forests in the state of New Jersey, USA, were compared. The forests, the Rutgers Ecological Preserve (RUEP) and Hutcheson Memorial Forest (HMF), represent accessible and inaccessible forests respectively. The study reported here evaluated the effects of visitation and accessibility on public perception of both sites. Residents near the RUEP and HMF, and visitors of both sites, were surveyed (n = 48). The results of the surveys demonstrated that the frequency of visitation and community location can have noticeable influences on a number of variables, including one&rsquo, s belief that forests provide important services and the thought that protected areas take away from an individual&rsquo, s freedom to use the area. A more positive view of the forests was present in those who visited the public forest most often.

It is distinguished by the possibilities of modeling the processes of regulation of the mechanism of development of complex facilities according to the factors of the modern industrial revolution. The application of the research results will improve the quality of energy and resource management processes by combining resources in the conditions of a high degree of diversification, possible when organizing a multi-purpose energy technology complex of low-waste type facilities.

BackgroundClimate change and pollution generated by the health care sector impose significant public health burdens. This study aimed to assess medical, nursing and physician assistant student knowledge and attitudes regarding climate change, pollution from the health care sector, and responsibility for resource conservation within professional practice.MethodsIn February–March, 2018, medical, nursing, and physician assistant students at Yale University (1011 potential respondents) were sent a 17-question online Qualtrics survey. Data analysis included descriptive statistics, as well as Fisher’s exact test and logistic regression to assess associations between variables of interest and the personal characteristics of gender, age, geographic place of origin, school, and year in school (among medical students).ResultsThe response rate was 28% (280 respondents). 90% felt that physicians, nurses, and physician assistants have a responsibility to conserve resources and prevent pollution within their professional practice. 63% agreed or strongly agreed that the relationship between pollution, climate change, and health should be covered in the classroom and should be reinforced in the clinical setting. 57% preferred or strongly preferred reusable devices. 91% felt lack of time and production pressure, and 85% believed that lack of education on disease burden stemming from health care pollution, were barriers to taking responsibility for resource conservation and pollution prevention. Women and physician assistant students exhibited a greater commitment than men and medical students, respectively, to address pollution, climate change, and resource conservation in patient care and professional practice.ConclusionWe found that health professional students are engaged with the concept of environmental stewardship in clinical practice and would like to see pollution, climate change, and health covered in their curriculum. In order for this education to be most impactful, more research and industry transparency regarding the environmental footprint of health care materials and specific clinician resource consumption patterns will be required.

Carbon capture and storage (CCS) reduces carbon dioxide (CO2) emissions by sequestration of captured CO2 for long-term storage whereas carbon capture and utilization (CCU) offers resource conservation benefits by displacing the need for extracted CO2 from natural sources. The integration of these two results in a carbon capture, utilization, and storage (CCUS) system, which either uses CO2 for profitable applications or stores it in the reservoirs. One of the key problems in CCS systems is to optimally match the sources (e.g., CO2 captured from fossil-fueled power plants) and the sinks (e.g., available geological reservoirs for storing the captured CO2). In practice, the geological storage sites may be available at different times and have limitations on the maximum CO2 storage capacity and the injectivity rate, subject to other geological characteristics. This work proposes an improved pinch analysis-based methodology by simultaneously considering the injectivity constraints and variable availability of ...

Studies of the electro-technological treatment of waste water of large livestock farms indicate the possibility of integrated implementation of the principles of hydrodynamic, electromagnetic, electrochemical and bioenergetic disinfection of objects infected with pathogenic microorganisms in the electro- technological installation (ETI). Improving the effi ciency of decontamination by means of ETI indicates the promise of this approach from the standpoint of energy, environmental and resource conservation, its transfer will signifi cantly reduce the man-made burden on the environment and ensure the required level of environmental safety of the population and staff .

Acquisitions of private forest rights have become a widespread conservation instrument. Over the past two decades, voluntary transactions have legally protected millions of hectares of private forestland in several countries, notably in the Americas. Limited evidence exists on the overall global magnitude and distribution of acquisitions, the factors driving site selection, and resulting ecological and social impacts. Improved behavioral models of landowners and conservation organizations might help steer acquisitions towards more efficient and equitable outcomes. Opportunities for building such models now exist owing to rapid advances in data, methods, and computing capacity.

The place, role, and tasks of engineering sciences in the modern Russian society have also been discussed.

The efficiency of energy conversion and transmission to the cutting zone may be increased by reactive-power compensation, with accompanying resource conservation.

Polymeric products such as plastics and rubbers are in widespread use, and the recycling of these polymeric materials has not kept pace with the increased production. There are serious environmental consequences to disposing of waste polymeric materials in landfills or incinerating them. Their low biodegradability makes it unpopular for both large and small industries to recycle them. This study reviews recycling strategies for waste thermoplastic and thermoset materials undertaken by industries and researchers. The primary objective is to review these techniques and identify those that can be applicable to the construction industry. There are three conclusions from this review: (1) Recycling of polymeric waste materials can be helpful to limit landfilled or incinerated waste plastic. (2) Proper selection of a recycling method for waste plastics and rubbers can effectively address the recycling problem without compromising the mechanical properties of the construction material. (3) The majority of the published articles in construction materials research have overlooked the importance of pre-treatment of waste polymeric materials to ensure compatibility with construction materials. Accordingly, there is an urgent need for understanding the science of functionalization of polymers to be able to tune surface properties of the recycled granules for targeted applications. This paper highlights critical research needs to facilitate the recycling of thermosets and thermoplastics to promote resource conservation and sustainability.

Carbon capture, utilization and storage (CCUS) is considered as one of the key strategies for mitigating climate change. This technology involves CO2 capture from stationary sources, followed by distribution of CO2 to different intermediate utilization and/or final storage options. CO 2 capture and utilization (CCU) by itself offers resource conservation benefits by displacing the need for extracted CO2 from natural sources. On the other hand, CO 2 capture and storage (CCS) provides CO2 emissions reduction by sequestration of captured CO2 for long-term storage. Combining CCS and CCU can potentially result in valuable symbiosis, but remains debatable due to gaps between the roles of these technologies in energy engineering. Such gaps have resulted in slower commercial deployment of CO2 “-capture. Some important issues resulting from these technologies have been addressed in previous studies through process systems engineering (PSE) methodologies, which are able to provide rigorous decision support during CCUS planning. This review paper provides an in-depth discussion of the state-of-the-art of these tools, and also discusses recent developments on integrating CCUS components in large-scale planning. While recent literature in this area reveals the availability of tools for planning and policy-making, further research opportunities are identified through the bibliometric trends that show how CCUS research can develop further.

Graphical abstract, Highlights • A novel method to quantify the ease of disassembly of products is presented. • The method relies on Maynard work measurement methodology (MOST). • The method is unambiguous and robust to be used in policy and by ecolabels. • The method makes a good trade-off between workability and accuracy. • The presented method is applied in a case study for an LCD monitor., Circular economy strategies encourage, among others, concrete actions to extend the product lifetime. Product’s repair and reuse, and component harvesting for reuse, all require the facilitated access to product components. Consequently, a reduction of the disassembly time and the related costs will increase the economic feasibility of product lifetime extension and therefore increase the viability of a circular economy in industrialised regions. Furthermore, disassembly has the potential to significantly increase the recycling yield and purity for precious metals, critical metals and plastics. For this reason, the European Commission and several ecolabels have considered to include design for disassembly requirements in legislation or voluntary environmental instruments. However, up to date, there is no standardised method to evaluate the ease of disassembly in an unambiguous manner with a good trade-off between the efforts required to apply the method and the accuracy of the determined disassembly time. The article proposes a robust method “eDiM” (ease of Disassembly Metric), to calculate the disassembly time based on the Maynard operation sequence technique (MOST). A straightforward calculation sheet is employed in eDiM to calculate the disassembly time given the sequence of actions and basic product information. This makes the results fully verifiable in an unambiguous manner, which makes eDiM suited to be used in policy measures in contrast to the results of prior developed methods One of the innovative aspects of eDiM is the categorization of disassembly tasks in six categories, which provides better insights on which disassembly tasks are the most time consuming and how the product design could be improved. The proposed method is illustrated by means of a case study of an LCD monitor. The presented case study demonstrates how the proposed method can be used in a policy context and how the calculated disassembly times per category can provide insights to manufacturers to improve the disassemblability of their products. The results also demonstrate how the proposed method can produce realistic results with only limited detail of input data.

Circular systems of reuse and recycling may stimulate resource conservation and thereby more sustainable outcomes for marketing systems. Automotive remanufacturing serves as a specific circular marketing system of reuse. However, supply shortages challenge the European remanufacturing marketing system, and current research focuses on micromarketing perspectives in this context.
