Pesticides are more and more used in African countries. The aim of this study is to evaluate the risk and the impact of pesticides on gardener’s health. It is a transversal descriptive study, which referred to vegetable growers, held in Lomé on the period from May 20 to June 5, 2017. Forty-eight (48) growers participated in the study. Men accounted for 70.8% of the study population against 29.2% of women. The level of education was primary (47.9%) in the majority of cases. Married people or couples represented 77.1% of cases. Most gardeners (72.9%) has no training in the use of pesticides. Pesticides were consistently applied (100%), including insecticides (72.7%), herbicides (9.1%), and fungicides (18.2%). Of 20 pesticides collected, 9 (45%) were approved by our authorities. Only 43.8% of growers were supplied with pesticides from authorized structures of agricultural products. Branches of plants (79.2%) were the spray means of most of the pesticides. Most gardeners (79, 2%) did not use personal protective equipment because of lack of resources for 81.6% of them. Water and environment contamination risk by pesticides was known by only 6.3% of gardeners. Among the adverse effects reported, pruritus was the majority in 85.4% of cases followed by headache (70.8%), cough (68.8%), and muscle pain (64.6%). The training of gardeners, monitoring and control of this informal sector, and the monitoring of unregistered pesticides will help to reduce the risk of poisoning of gardeners and consumers of vegetables as well as environmental pollution.

The mobile phone has become an indispensable mean of communication in the world today, and for teenagers specifically has become de rigueur in everyday life. The eagerness of teenagers to embrace mobile devices can be associated with such devices' instrumental as well as social and expressive functions. However, these functions are intertwined with critical impacts on the interaction between teenagers and parental/peer groups. On the one hand, the mobile phone acts as a symbolic “umbilical cord” that provides a permanent channel of communication, intensifying parental surveillance. On the other hand, it creates a greater space for interaction with peers beyond parental monitoring and control. This article summarizes current research and presents an empirical example of the impact of teenagers' mobile phone communication on the dynamics of parental and peer group interactions during their socialization and emancipation from the familial sphere.

Although visceral leishmaniasis disease is controlled overall in China, it remains a serious public health problem and remains fundamentally uncontrolled in Jiashi County, Xinjiang Uygur Autonomous Region. During 2005–2015, there were two outbreaks in Jiashi County. Assessing the influence of meteorological factors on visceral leishmaniasis incidence is essential for its monitoring and control. In this study, we applied generalized estimating equations to assess the impact of meteorological factors on visceral leishmaniasis risk from 2005 to 2015. We also compared meteorological factors among years with Kruskal–Wallis test to explore possible reasons behind the two outbreaks that occurred during our study period. We found that temperature and relative humidity had very significant associations with visceral leishmaniasis risk and there were interactions between these factors. Increasing temperature or decreasing relative humidity could increase the risk of visceral leishmaniasis events. The outbreaks investigated might have been related to low relative humidity and high temperatures. Our findings will support the rationale for visceral leishmaniasis control in China.

Innovation is an important driver of economic progress, benefiting consumers, business and the economy as whole. However, innovation companies face high risks because innovation requires a lot of resources, and it is difficult to predict a payback period in advance. This is common for all types of innovation, but especially to technological innovation. One of the least researched technological innovations is telematics, innovative transport monitoring and control technology solutions. Those are widely applied in logistics, car-sharing platforms and the public transport sector. These innovations help to achieve the goals of the companies that buy and install them, but question what impact they have on the competitiveness of the companies that create these innovations remains a matter of debate. To fill this gap, the purpose of this article is to determine the impact of technological innovation on the competitiveness of telematics companies. In pursuit of this goal, the concepts of technological innovation and competitiveness are revealed. The definition of telematics innovation and its significance for the competitiveness of enterprises was also formed. The empirical part discusses the telematics market, provides the analysis of the main competitiveness indicators of 8 telematics companies and their changes, as well as the analysis of the research and development (R&D) costs and the impact of innovations on competitiveness. Applied research methods: a critical analysis of scientific literature, generalization, systematization of data, computation, and comparison of relative indicator, data dispersion indicator, and dynamics indicator, correlation, and regression analysis. The research reveals that creation and development innovation are related to competitiveness of telematics companies. However, excessive investment into innovation no longer generates positive return.

Ownership structure or the stakeholder structure of an organization often play significant role in operations decision, monitoring and control. This as a result possesses influences over process and hence performance. On the other hand, the role of stakeholders and respective conflict of interests can also be not ruled out. Under such circumstances, assessing the impact of organizational structure or stakeholder pattern and firm performance becomes inevitable to assess. In addition, the relationship between the investment pattern and respective conflicts of interests is inevitable to be examined. To ensure investment security corporate governance has played vital role that suggests assessing the inter-relationship between the stakeholder pattern and firm performance. With this motivation, in this paper an empirical study has been done to examine the impact of internal shareholding patterns on the associated firm’s performance. In this paper we have performed an empirical study where the aforementioned relationship has been examined for Indian listed NIFTY 50 companies for the duration of the financial year 2011 to 2016. Our empirical results provide evidence that insider shareholding is positively and significantly related to the firm performance as measured by market capitalization; market value by book value and Tobin’s Q.

The qualitative research presented in this article attempts to show the impact of teacher-initiated activities on six-year-old children’s metacognitive monitoring and control abilities. The metacognitive model is discussed, research findings that substantiate the development of separate components of metacognitive regulation are analyzed, and the educational ways that promote metacognitive development in children are systematized. The outcomes of the research show that teacher-initiated activities stimulate and encourage children to find and apply more diverse ways of metacognitive monitoring and control. After teacher-initiated activities, the target group children demonstrated, identified, and verbalized the following ways of acting and learning that had not been noticed in their self-initiated activities in the area of metacognitive monitoring, namely, thinking while doing, modelling, acting by scheme/without a scheme, and activity by self-created strategies. In the area of metacognitive control, the children showed the ability to challenge themselves to do better than before, think and do as a continuous, unbroken control and implementation process, and control performance consistency.

Pesticides are abundantly used in agribusiness and can be damaging to health and the environment. Society in general and agricultural, environmental and health institutions in particular have a legal and statutory duty to supervise their use. To identify and analyze these actions, interviews were conducted with managers of the municipal offices and union leaders representing the workers and farmers. Managers and rural producers were of the opinion that pesticides are essential to productivity and do not generate any impact on health and the environment. No policies or institutional relations monitoring pesticide use were identified or being considered. Rural workers' unions do not take any political initiatives to benefit the health of the workers themselves, their families and that of society in general. The conclusion draws is the pressing need to develop a model for sustainable agriculture, healthy and free of pesticides and that organized society and responsible institutions must undertake actions that meet the needs of the people who working on the farms or consume the agricultural products harvested there, especially controlling risks and consequences that can and must be avoided.

Objectives The aim of this study was to assess the impact of onychectomy (declawing) upon subsequent development of back pain and unwanted behavior in cohorts of treated and control cats housed in two different locations. Methods This was a retrospective cohort study. In total, there was 137 declawed and 137 non-declawed cats, of which 176 were owned cats (88 declawed, 88 non-declawed) and 98 were shelter cats (49 declawed and 49 non-declawed). All cats were physically examined for signs of pain and barbering. The previous 2 years of medical history were reviewed for documented unwanted behavior such as inappropriate elimination and biting with minimal provocation and aggression. All declawed cats were radiographed for distal limb abnormalities, including P3 (third phalanx) bone fragments. The associations of declaw surgery with the outcomes of interest were examined using χ2 analysis, two sample t-tests and manual, backwards, stepwise logistic regression. Results Significant increases in the odds of back pain (odds ratio [OR] 2.9), periuria/perichezia (OR 7.2), biting (OR 4.5) and barbering (OR 3.06) occurred in declawed compared with control cats. Of the 137 declawed cats, 86 (63%) showed radiographic evidence of residual P3 fragments. The odds of back pain (OR 2.66), periuria/perichezia (OR 2.52) and aggression (OR 8.9) were significantly increased in declawed cats with retained P3 fragments compared with those declawed cats without. Optimal surgical technique, with removal of P3 in its entirety, was associated with fewer adverse outcomes and lower odds of these outcomes, but operated animals remained at increased odds of biting (OR 3.0) and undesirable habits of elimination (OR 4.0) compared with non-surgical controls. Conclusions and relevance Declawing cats increases the risk of unwanted behaviors and may increase risk for developing back pain. Evidence of inadequate surgical technique was common in the study population. Among declawed cats, retained P3 fragments further increased the risk of developing back pain and adverse behaviors. The use of optimal surgical technique does not eliminate the risk of adverse behavior subsequent to onychectomy.

Introduction. Due to the impact of the global financial crisis and the growth of competition in the international market, control in the enterprise management is becoming important. It provides feedback between the control and managed subsystems of the enterprise. The purpose of the research is to substantiate the effectiveness of the monitoring and control system in the agricultural enterprises management in an unstable economic environment. Results. It is established that the existing approaches to the agricultural enterprise management do not contribute to the effective implementation of monitoring and control. The number of problems in the process of agribusiness management were identified based on expert analysis. It is determined that the development of strategic management in the agricultural enterprises activities is hampered by the lack of use of appropriate monitoring and control tools. The guidelines of agrarian business entities are determined in accordance with the market concept of enterprise management. The coefficient analysis of capacity utilization and profitability of agricultural enterprises is carried out. The inconsistency of the existing approaches of agricultural enterprises management to the requirements of the market environment has been established. It is revealed that the imperfect organization of enterprise management contributes to the formation of an unstable information base of enterprise control. The operative orientation of control in the enterprise management of the agrarian sphere and neglect of strategic factors of success are determined. It is substantiated that the integration of economic monitoring and control tools in the management system contributes to the growth of enterprises economic efficiency. Conclusions. The formation of strategic goals of agricultural enterprises is based on the distorted implementation of the sustainable development concept. The presence of a significant number of factors is determined that inhibit the process of increasing the investment attractiveness level and economic efficiency of agricultural businesses. Keywords: monitoring, control, enterprise management, agrarian business entity, efficiency, strategic management, monitoring and control tools, information base.

Since December 2019, SARS-CoV-2 infections have altered many aspects of our societies. Citizens were faced with circumstances to which even experts and scientists did not yet know the answers and were applying the scientific method to make daily steps of progress towards better understanding the threat and how to contain it. Within a year, several vaccines were produced to protect individuals from the virus, thereby resolving the most important medical problem. However, not just medical issues call for the application of the scientific method. The management of epidemics also can, and in fact should, benefit significantly from a science-based approach. The novel complexity of the situation left us torn between permissive and authoritarian approaches of containment, and it is still subject to debate what works best and why. In our contribution, we model the emerging complexity of the epidemics and propose a scientific-based data driven approach that aims to aid the decision makers in their focus on the most relevant issues and thus helping them to make informed and consistent decisions. The resulting monitoring and control system, termed COVID-19 vigilance, helps with risk assessment and communication during regional COVID-19 outbreaks. The system is based on the Cynefin decision complexity framework and the universal process model, and it uses several mathematical models that describe epidemic spreading. Different future scenarios are used to predict the impact of realistic, optimistic, and pessimistic outcomes, in turn allowing for a more efficient communication of involved risk.
