The Impact

The objective of this study was to determine the impact of a range of management systems on weed communities in cropped fields on farms in Saskatchewan. Farms (n = 28) with management systems defined by a combination of different cropping histories and chemical input levels were selected. Fields were surveyed on each farm in 1995, 1996, and 1997 after any post-emergent weed control to ensure that their weed communities reflected the impact of all agronomic management practices typical of the management system. Canonical correspondence analysis was used to determine whether weed communities were significantly correlated with management system after removal of variance due to ecoregion and year. The largest difference in weed communities attributable to farming system was between the systems with annual cropping histories and those that included perennials in the cropping history. Thus, the life history of the weeds reflected the life history of the crops. Herbicide use was correlated with the next largest difference between systems. A significant association between weed communities and different management systems indicates that weed species are being selected for by these systems. If such selection pressure continues, these species may become a threat to the system's sustainability.

The relationship between the weed communities and environmental variables such as soil, crop, and management was investigated in two provinces of Canada. The frequencies of weed species were recorded in cereal and oilseed fields in Saskatchewan (2244 fields over 4 years) and Manitoba (864 fields over 3 years), Canada. Information on some of the physical characteristics of the fields and on the management practices imposed on them was also collected, in part by questionnaire. The two kinds of data were ordinated together using canonical correspondence analysis to assess the relationships between the species and the environmental variables. In the Saskatchewan data, there was a clear and consistent separation of the species into groups along an axis correlated with soil zone and the associated climatic gradient. In the Manitoba data, the same groups of species did not separate as clearly or as consistently, although geographic region was a major determinant of the weed communities. The greater variability may be due to the fact that the gradient of soil types is much more restricted in Manitoba and not as closely correlated with climatic conditions. In both provinces, culture practices were less important as correlates of the weed community composition than soil type or, to a certain extent, the previous crop. Key words: canonical correspondence analysis, cereal crops, oil seed crops.

The Impact

Developing countries face various challenges in implementing bio-risk management systems in the laboratory. In addition, educational settings are considered as workplaces with biohazard risks. Every activity in a laboratory facility carries many potential hazards that can impact human health and the environment and may cause laboratory incidents, including Laboratory Acquired Infections (LAIs). In an effort to minimize the impact and occurrence of these incidents, it is necessary to evaluate the implementation of a bio-risk management system in every activity that involves handling biological agents. This study was conducted in an Indonesian higher-education institution, herein coded as University Y. This is a descriptive, semi-quantitative study aimed at analysing and evaluating the implementation of the bio-risk management systems used in laboratories by analysing the achievements obtained by each laboratory. The study used primary data that were collected using a checklist which referred to ISO 35001: 2019 on Laboratory Bio-risk Management. The checklist consisted of 202 items forming seven main elements. In addition, secondary data obtained from literature and document review were also used. The results show that out of 11 laboratories examined, only 2 laboratories met 50% of the requirements, which were Laboratory A and B, achieving good performance. Regarding the clauses of standards, a gap analysis identified leadership, performance evaluation, and support as elements with the lowest achievement. Therefore, corrective action should be developed by enhancing the commitment from management as well as improving documentation, policy, education and training.

The Impact

The impacts of a range of farm-management practices on house mouse (Mus domesticus) populations were tested in a large replicated field study in a complex irrigated farming system in southern New South Wales, Australia. An advisory panel, made up of farmers, extension officers, industry representatives and scientists developed a series of best-practice farm-management actions to minimise the impact of mice. Twelve experimental sites were split into six treated sites, where farmers were encouraged to conduct the recommended practices, and six untreated sites, where farmers conducted their normal farming practices. Mouse abundance was generally low to moderate for the 4-year project (5–60% adjusted trap success). We found significant reductions in population abundance of mice on treated sites when densities were moderate, but no differences when densities were low. Biomass of weeds and grasses around the perimeter of crops were significantly lower on treated sites because of applications of herbicide sprays and grazing by sheep. We could not detect any significant difference in mouse damage to crops between treated and untreated sites; however, levels of damage were low (<5%). Yields of winter cereals and rice crops were significantly higher on treated sites by up to 40%. An analysis of benefits and costs of conducting farming practices on treated sites compared with untreated sites showed a 2 : 1 benefit to cost ratio for winter cereals, 9 : 1 for rice and 4 : 1 for soybeans.

The Impact

The aim of the study is to establish the presence of a causal relationship between the historical development of the accounting system (its modification) with management revolutions, identification of new characteristic features and accounting functions arising from changes in management approaches and requirements for accounting information for management purposes. Achieving the goal of the study involves identifying opportunities for further improving the accounting system based on the experience of its genesis under the influence of managerial revolutions. The methodological basis of the study is the dialectical method of cognition. The use of the historical method allowed to establish the logical dependence of the evolution of accounting on the requirements of the management system. Analytical and systematic methods were used to identify and form descriptions of the relationship of the accounting system in budgetary institutions with the processes of management system transformation and management revolutions. The impact of managerial revolutions on the accounting system in Ukraine and their consequences are established on the basis of an empirical generalization of historical archival and literary descriptions, as well as a critical analysis of the regulatory regulation of accounting, its norms and practices. The existence of a direct influence of managerial revolutions on the content, requirements, principles and methods of accounting is justified. The above result is based on the results of the analysis of the historical content of accounting, its evidence (accounting documents), as well as the assessment of the functions of the persons who carried out the accounting. The study of works on the history of accounting made it possible to assess the genesis of the introduction of the institutional approach and accounting as the basis for its transformational changes aimed at strengthening compliance with management needs. The study showed that accounting is changing under the influence of transformations in management, changes in its requests, determined by the existing needs of management.

It is now clear that over use of pesticides and intensive management of orchards can lead to drastic declines in apple pollinator abundance and crop failures. During the period of study a grower’s survey was conducted to know about knowledge of farmers on native insect pollinators, pollinator management practices, their perceptions of the importance and utility of native pollinators, and their attitudes regarding pesticide application. Despite of having significant knowledge of managed pollination, only few farmers (2%) adopted supplementary methods of pollination (renting honey bee colonies, hand pollination etc.). In Pulwama, 60% of farmers had knowledge about native insect pollinators and 40% did not have any idea of native pollinators and in case of Shopian, the figures were fifty-fifty i.e. 50% had knowledge about native insect pollinators and 50% were unaware. During the period of investigation, native insect pollinators were sampled from different apple orchards under different management systems in early spring during apple flowering. A total of 17 species of insect pollinators belonging to 11 families and 3 orders_ Hymenoptera, Diptera and Lepidoptera registered their occurrence at all the studied apple orchards of the Kashmir Valley. At all the study sites i.e. apple orchards under different management systems, family Halictidae and Empididae registered their presence as dominant groups. The % family contribution of the former at different orchard types decreased with increase in the intensity of the management system and the % family contribution of the later however, showed a direct relationship with the management system found, i.e. the more intense the system, the more abundant was the group. Other groups in general did not show any greater differences in abundances at different sites studied.

Arguments have been made that the decline in Antigua’s sugar production was a byproduct of poor land management practices, depletion of soils, and outdated agricultural techniques and technology. Recent work at Betty’s Hope suggests that not all plantations were susceptible to poor decision-making and that some plantations may have superseded social-ecological constraints despite the sugar industry’s inevitable decline. This chapter by Cory Look focuses on key aspects of land-use and landscape change at Betty’s Hope, particularly during the eighteenth century, when the plantation experienced rapid growth and economic prosperity. Look discusses the impact on enslaved Africans through examination of changes to slave quarter spaces and provisioning grounds by managers of local resources. The analysis was possible through remote sensing and multiple surveys conducted over ten field seasons.

The Impact

PurposeThe first goal of the article was to examine how the perception of the role and scope of operation of maintenance services in the enterprise changes, depending on whether the company has an integrated management system (IMS), only a quality management system implemented in accordance with ISO 9001 and in the absence of a formal, certified management system. The second goal was to propose a model for assessing the quality of maintenance service functioning in enterprise with IMS implemented.Design/methodology/approachThe author's experience of over 1,000 audits in enterprises in various industries: food, automotive, construction, petrochemical, electronic and so on was used in the work. The audits were carried out in three types of companies: which had IMSs (800 audits), which only had a system implementation certificate ISO 9001 (140 audits) and without any standardized management system implemented (so-called second-party audits, commissioned by the client of the audited company.FindingsThe most important conclusion is – the role of UR services in enterprises with the implemented IMS is much broader and goes beyond the classic framework for planning, implementation and settlement of maintenance and repair work. Maintenance is understood more broadly and includes in its scope also the safety of people and the environment, the efficiency of production and consumption of utilities as well as the quality of products and services. Maintenance issues include not only strictly technical aspects but also economic, logistic, legal and organizational and management aspects.Practical implicationsResearch shows that enterprises, especially those with high technical and organizational culture, should not treat management systems as costs, but as a driving force for the implementation of new technologies, new organizational solutions and the development of employees' competences.Social implicationsBroad views on stakeholders of maintenance services (including employees, their families, control institutions) and their requirements make enterprises begin to see the need to maintain the so-called lifetime balance, as well as the safety and comfort of work of employees of these services.Originality/valueThe author did not find in literature any reports on studies of the impact of formal, certified management systems on the quality of maintenance services; this article shows that this impact is large and, above all, positive; with such a broad understanding of the role of maintenance, there is a need to develop a common platform for such seemingly distant concepts as machine technical condition or fatigue life versus cost accounting and quality management.

The improved growth performance of chicks determines the production efficiency of chicken to local chicken farmers. Little has been done to understand the contribution of management systems and practices to the growth performance of chicks from farmers who are involved in rearing local chickens in Dodoma. We focused on assessing how the growth performance of chicks (length and weight) from local chicken farmers is affected by management systems (Free range and semi-intensive systems), management practices such as water provision, supplement feeding, regular cleaning, flock size, and size of banda (hut) used to raise chickens. Data were collected for 8 rounds within 2 months (once per week) from 5 farmers in three wards: Nkuhungu (n=2), Mbwanga (n=2), and Mtube (n=1). In each round, data were collected from 10 chicks per farmer (n=400 chicks for all 8 rounds and 5 farmers). Kruskal Wallis was used to determine the variation in growth performance while generalized linear model was used to assess the effect of flock size, management system on the growth performance of chicks. Growth performance was significantly increased and affected by age (P less than 0.05). The management system significantly contributed to the growth performance of the chicks (P less then 0.001). In addition, the small size of the banda (hut) with large flock size reduced the growth performance of chicks due to increased competition in terms of space, supplements, water supplied, feed provided, and treatment (P less than 0.05). In raising local chicken, local farmers need to be concerned in applying management practices such as supplement feeding, treatment, flock size and size of huts.

Assessment Results

The article considers the current problem of low efficiency of tools and methods used to assess the project management systems of complex engineering facilities. The problem is important today because engineering companies strive to increase their rating in a highly competitive market, and this issue is of a special concern in the international market of goods, works and services. The article presents the methodology for the assessment of the project management system, based on the simultaneous cross-section use of approaches to the assessment of project management and personnel management processes (the so-called “processes – personnel” pair) with the use of questionnaire-dialog forms of data collection. The essence of the study was to search for patterns of cross-assessment results, their comparison and determination of algorithms of mutual influence on each other, and what is necessary for a more accurate assessment of the management system. The scientific novelty of the research is the development of a set of interrelated indicators of the management system behavior in a company. The presented method was tested by the team of authors of this article during the management assessment of the international project on the construction of a thermonuclear reactor (ITER, France) in 2020. The results of the study revealed the comparability of the assessment results, confirmed the impact of the assessment results on each other and determined the possibility of predicting the assessment results per individual indicators, depending on the state of the management system in the “process-personnel” pair. This method can be used to assess the management systems of any project-oriented companies implementing capital construction projects. In the future, it can become the basis for creating a specialized standard for assessing the construction project management systems.

The article is an attempt to present the two modern concepts of safety management systems. The first is the sunflower pyramid used especially in Europe, the second is the ISO 39001 standard (Road Safety Management System) of international scope. The idea and possibilities offered by use of both concepts of safety management, as well as an attempt to assess the impact of their actions on decrease in fatalities in selected EU countries, were presented. As a result of the conducted analyses, a downward trend was noted as to the number of certificates issued for compliance with the ISO 39001 standard in the world, which may indicate an appearance of the more adequate management systems, or other tools or concepts to improve the road safety, or inadequate education society and low level of awareness in this area of stakeholders, including politicians, scientists, producers, drivers (professional and reliable), as well as other road users, including unprotected ones.
