AbstractDrought in the forest is not only a prolonged state of water shortage, but also an occasion where interactions between plants and fungi are affected. Water efficiency accelerates a range of pathologies in interactions between organisms, influencing the ecosystems and their interacting biological components. This study focuses on the role of mycorrhizal and endophyte fungi in alleviating the effects of soil water shortage, and on the impact of their altered activity during drought on the health of trees. The issues presented here show the fundamental role of the mycorrhizal mycelium and the mechanism of water transport to the plant in the course of other phenomena (withering, pathogenesis, endophytes biology) that occur in trees under influence of drought, with particular attention on managed coniferous stands. Conclusions resulting from published information on this topic emphasize the negative impact of soil moisture deficiency on the ectomycorrhizal fungi functioning and, in contrast, on the promotion of the growth of some endophytes, pathogens and hemi-parasitic mistletoes (Viscum spp.).

The Impact

The success of a construction project is a widely discussed topic, even today, and there exists a difference of opinion. The impact of communication and conflict on project success is an important, but least addressed, issue in literature, especially in the case of underdeveloped countries. Miscommunication and conflict not only hinder the success of a project but also may lead to conflicts. The focus of this paper was to examine the impact of communication on project success with the mediating role of conflict. By using SPSS, demographics, descriptive statistics and correlation were determined. Smart PLS version 3.0 was used for confirmatory factor analysis (CFA), internal accuracy and validity estimates, hypothesis checking and mediation testing. The results showed that formal communication has a negative impact on the success of a construction project, resulting in conflicts among project team members, whereas informal communication and communication willingness have a positive impact on project success because people tend to know each other, and trust is developed. Task, process and relationship conflicts were used as mediating variables. It was found that task conflict effects the relations positively because project team members suggest different ways to do a certain task, and, hence, project success is achieved. On the contrary, process conflict and relationship conflict have a negative impact on communication and project success. Both of these conflicts lead to miscommunication, and project success is compromised. Hence, it is the responsibility of the project manager to enhance communication among project team members and to reduce the detrimental effects of process and relationship conflict on project success.

The Impact

Abstract Scholars have long debated whether populism harms or improves the quality of democracy. This article contributes to this debate by focusing on the impact of populist parties in government. In particular, it inquires: (1) whether populists in government are more likely than non-populists to negatively affect the quality of democracies; (2) whether the role of populists in government matters; and (3) which type of populism is expected to negatively affect the quality of liberal-democratic regimes. The results find strong evidence that the role of populists in government affects several qualities of democracy. While robust, the findings related to (2) are less clear-cut than those pertaining to (1). Finally, regardless of their role in government, different types of populism have different impacts on the qualities of democracy. The results show that exclusionary populist parties in government tend to have more of a negative impact than other forms of populism.

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.

The diffusion of the technological innovation can affect the agricultural sector in the three-sided (social, economic and environmental), a hand, it can contribute to solve problems of the agricultural sector: the effects of the climatic changes, the farming exodus and the migration and the problems of poverty and it can improve the agricultural productivity. But on the other hand, he can lead to new problems, such as depletion of energy resources caused by excessive use of energizing technologies, pollution of air and water and the destruction of soil by industrial waste. This paper aims to theoretically and empirically analyze the role of technological innovation in improving agricultural sustainability through the impact of mechanization on agricultural productivity, energy production and net income per capita for a panel of three Maghreb countries (Algeria, Morocco and Tunisia) during the period 1997-2012. By using simultaneous equations, the authors' finding that technological innovation cannot achieve the purpose of sustainable development in the agriculture sector in the Maghreb countries through the negative impact of mechanization and research and development on agricultural productivity.

The Impact

Internal control plays a role in risk prevention for firms when dealing with serious emergencies, which ensures the sustainable development of firms during a crisis. Based on the rapid outbreak of COVID-19 in China, this paper empirically tests whether internal control alleviates the negative impact of the pandemic on firm performance. Using a sample of Chinese listed firms from the first quarter of 2019 to the third quarter of 2020 and employing the difference-in-difference (DID) method, we find that the firms with a higher quality of internal control achieve better financial performance during the pandemic period; the more serious the pandemic is, the more obvious effect internal control plays. Furthermore, we consider the industry heterogeneity and firm heterogeneity of the risk resistance effect of internal control. In the manufacturing industry, which is a “disaster zone” of the pandemic, and the non-high-tech industry with a low degree of digitization, internal control can play a more important role in firms’ performance. Moreover, for state-owned enterprises, and firms with strong financing constraints, the role of internal control is more prominent. The above results provide empirical evidence for the risk prevention function of internal control and shed new light on the measures for firms to resist emergencies in the future.

Background: Uniform has traditionally been worn in psychiatric inpatient and other mental health settings, but there has been a move to non-uniform in recent years. Some services have made the change back to uniform, raising questionsabout the potential impact on patients and staff.Aim: To review the impact of uniform within a psychiatric inpatient or mental health setting.Method: Databases were searched for articles exploring the impact of uniform use using specified search terms. Articles were assessed for suitability with inclusion and exclusion criteria, critically appraised, then analysed for themes using thematic analysis.Results: 17 papers were included in the review. Thematic analysis identified five main themes and 29 subthemes. Main themes were Attitudes and interactions, A freer environment, Are you both nurses?, The ‘ideal self’ and There are more important things. A critical appraisal of the articles suggested issues with validityand reliability, which are discussed.Discussion: Studies identified that wearing non-uniform facilitated positive changes in both patients and staff. This raises the potential negative impact of uniform on both patients and staff, and the role of power imbalance in these settings is discussed. Further themes around identification of staff out of uniform were considered.Implications for practice: The use of uniform in mental health and psychiatric inpatient settings should be considered carefully, due to the potential negative impact, whilst also recognising the importance of staff identification and supporting professional identity.

Abstract. Narcotics in unattended use can have a negative impact. The impact is potential to destroy the youth generation. It is necessary to hold the drug prevention programs, especially in schools as one of ways to prevent the widespread negative impact. The prevention can be through the role of parents, teachers and stakeholders as part of the community. The teachers’ role is divided into four sub-role, namely as educators, as advisors, as mentors, and particularly as problem solvers. The role of teachers certainly will not have power if it is not supported by the role of schools. Effots that are conducted by school stakeholder are as follow: a) compose the school rules; b) conduct inspections intensively and spontaneously; c) cooperate with related institutions for counseling and socialization; d) utilize extracurricular activities as means of prevention; e) integrate drug awareness into learning curriculum; (f) maximize the tasks as the effort of drug abuse prevention. Expectedly, these drug prevention efforts can be implemented by all schools as one of ways to prevent the destruction of the nation through NAPZA. Abstrak. Narkoba dalam penggunaan yang tidak diawasi dapat menimbulkan dampak negatif. Dampak tersebut tidak menutup kemungkinan dapat merusak generasi muda. Salah satu cara agar bahaya tersebut tidak meluas dampaknya, maka perlu program pencegahan terutama di sekolah. Pencegahan tersebut dapat melalui peran orang tua, guru dan pemangku kebijakan sebagai bagian dari masyarakat. Peran guru dibagi dalam empat yakni sebagai pendidik, penasehati, pembimbing dan lebih utama lagi sebagai problem solver. Peran guru ini tentu tidak akan memiliki kekuatan jika tidak didukung oleh peran sekolah. Upaya yang dilakukan oleh pihak sekolah adalah a) membuat tata tertib sekolah, b) melakukan razia intensif dan spontan, c) bekerjasama dengan instansi terkait guna penyuluhan dan sosialisasi, d) menggunakan ekstrakurikuler sebagai sarana pencegahan, e) memasukkan materi tentang narkotika ke dalam kurikulum pengajaran, f) memaksimalkan tugas dalam upaya pencegahan penyalahgunaan NAPZA. Diharapkan agar upaya pencegahan tersebut dapat diikuti oleh semua sekolah sebagai salah satu usaha untuk mencegah rusaknya anak bangsa melalui NAPZA.
