Control of maize late wilt disease (LWD) has been at the forefront of research efforts since the discovery of the disease in the 1960s. The disease has become a major economic restraint in highly affected areas such as Egypt and Israel, and is of constant concern in other counties. LWD causes dehydration and collapsing at a late stage of maize cultivation, starting from the male flowering phase. The disease causal agent, Magnaporthiopsis maydis, is a seed- and soil-borne phytoparasitic fungus, penetrating the roots at sprouting, colonizing the vascular system without external symptoms, and spreading upwards in the xylem, eventually blocking the water supply to the plant’s upperparts. Nowadays, the disease’s control relies mostly on identifying and developing resistant maize cultivars. Still, host resistance can be limited because M. maydis undergoes pathogenic variations, and virulent strains can eventually overcome the host immunity. This alarming status is driving researchers to continue to seek other control methods. The current review will summarize the various strategies tested over the years to minimize the disease damage. These options include agricultural (crop rotation, cover crop, no-till, flooding the land before sowing, and balanced soil fertility), physical (solar heating), allelochemical, biological, and chemical interventions. Some of these methods have shown promising success, while others have contributed to our understanding of the disease development and the environmental and host-related factors that have shaped its outcome. The most updated global knowledge about LWD control will be presented, and knowledge gaps and future aims will be discussed.

Summary Yokkaichi asthma, one of the four big pollution diseases of Japan, occurred as a result of the operation of local petrochemical complexes in the city of Yokkaichi in the early 1960s. This article explores how Yokkaichi asthma was caused, how it was certified by local government and how the air pollution victims ultimately won a lawsuit against the polluting corporations. Yoshida Katsumi, a Medical Professor at Mie Prefectural University, consulted the Atomic Bomb Medical Law to establish Yokkaichi’s own certification system. Because both leukaemia and asthma are non-specific diseases, they may also be caused by non-pollution-related factors. In the Yokkaichi lawsuit, Yoshida applied the epidemiological causation to the legal judgment for the purpose of providing compensation to individuals. As the case for compensation unfolded from 1967 to 1972, epidemiological knowledge, legal theory and social norms were deployed to advance the plaintiffs’ claim, whose success set a good example for other legal proceedings.

There has been an important shift in the pattern of divergence between consumer and environmental protection policies in Europe and the United States. From the 1960s through the mid 1980s American regulatory standards tended to be more stringent, comprehensive and innovative than in either individual European countries or in the European Union (EU). However, since around 1990 the obverse has been true; many important EU consumer and environmental regulations are now more precautionary than their American counterparts.The ‘new’ politics of consumer and environmental regulation in Europe are attributable to three inter-related factors: a series of regulatory failures within Europe, broader and stronger political support for more stringent and comprehensive regulatory standards within Europe and the growth in the regulatory competence of the European Union.In many respects, European regulatory politics and policies since the 1990s resemble those of the United States during the 1970s. Thus health, safety and environmental politics and policies in the United States are no longer as distinctive as many scholars have portrayed them.

The high clinical mortality and economic burden posed by invasive fungal infections (IFIs), along with significant agricultural crop loss caused by various fungal species, has resulted in the widespread use of antifungal agents. Selective drug pressure, fungal attributes, and host- and drug-related factors have counteracted the efficacy of the limited systemic antifungal drugs and changed the epidemiological landscape of IFIs. Species belonging to Candida, Aspergillus, Cryptococcus, and Pneumocystis are among the fungal pathogens showing notable rates of antifungal resistance. Drug-resistant fungi from the environment are increasingly identified in clinical settings. Furthermore, we have a limited understanding of drug class-specific resistance mechanisms in emerging Candida species. The establishment of antifungal stewardship programs in both clinical and agricultural fields and the inclusion of species identification, antifungal susceptibility testing, and therapeutic drug monitoring practices in the clinic can minimize the emergence of drug-resistant fungi. New antifungal drugs featuring promising therapeutic profiles have great promise to treat drug-resistant fungi in the clinical setting. Mitigating antifungal tolerance, a prelude to the emergence of resistance, also requires the development of effective and fungal-specific adjuvants to be used in combination with systemic antifungals.

Worldwide, higher education is considered as a driver of economic, social and the political changes driving global knowledge (Ngoma, Ntale & Abaho 2017). Besides the increase access to education, the quality of graduate reflected by their academic performance is worrying (Ridzuan, Yunus, Abdullah, Bakar, Azlan & Ramlan 2018). Paloș, Maricuţoiu and Coste (2019), noticed that a large number of enrolled student graduates with poor grades or fail to graduate. In an attempt to retain and capture market share with the increase in study options, higher education all over the world are constantly struggling to provide a distinctive learning experience necessary to improve their students' performance (McGillicuddy & McGloin 2018). Considering the increasingly competitive and dynamic education environment, higher education can no longer ignore the needs and factors required to enhance student performance. Poor student performance in higher education institution has been a major source of concern for decision makers in the educational sector. Lai (2015), posits that the poor student performance can be attributed to the student-related factors such as attendance classes, score in high school, competence in quantitative subject and preparation to exam or tests. Moreover, Glew, Ramjan, Salas, Raper Creed and Salamonson (2019) state that poor attitude to the subject, lack of innovative teaching techniques, inadequate materials and inadequate funding to support the students negatively impact the performance of student. In addition, most prior research on performance has been done at high school or colleges, rather than at university level (Organisation for Economic Co-operation and Development (OECD) 2017). While, studies on student performance in developed countries are well documented, little attention has been dedicated in less developed countries such as South Africa (Ngoma et al., 2017). Given the difference between culture in developed and less developed counties, this study focused on investigating the antecedents of student performance in South Africa. Keywords: Student royalty, student satisfaction, student motivation, student performance

This chapter examines why the UK Parliament has invested heavily in public engagement over the last decade. Since the 1960s, the UK Parliament has been facilitating public engagement through a variety of ways. However, it is also an institution which is far more vulnerable and criticized by both the public and media. The chapter first defines public engagement before discussing the importance of parliamentary public engagement today. Four key inter-related factors that explain the rise in the importance of public engagement for parliaments are highlighted: the steady trend of increasing scepticism towards politics; the improved access to education and information; the increased opportunities created by digital media; and the growing appeal of participatory democracy. The chapter goes on to analyse how public engagement developed in Parliament and asks whether this has led to changes in public attitudes towards the institution.

1. Within 24 hours following intravenous inoculation with rabbit virulent strains of pneumococcus Type III, most rabbits develop infections of one or both knees. The frequency of bilateral knee joint involvement increases as the duration of the disease is prolonged. 2. The spinal fluid, aqueous humor, and bladder urine remain sterile at a time when the knee joints contain pneumococci. Subsequently, however, they may be invaded. 3. The administration of a single dose of type specific horse immune serum, at a period when in all probability one or both knee joints contain organisms, appears to be ineffective in bringing about resolution of the infections process in these sites, even though horse serum constituents may be demonstrated serologically to be present within the joint cavities.

Abstract Background Diseases of the heart and vascular system are the leading cause of mortality in the Philippines. Hypertension, the most important modifiable risk factor, has a prevalence rate of 28% and a control rate of 20%. Despite the proven efficacy of pharmacologic treatment, medication adherence is reported to be as low as 66%. While there are publications that reported factors that affect adherence in Filipinos, there are no existing research that evaluated them systematically. This review is conducted to present and synthesize findings of published literatures. Methods Databases—PubMed, Scopus, Wiley Online library, Science Direct, JSTOR, Web of Science, SAGE journals, and Cochrane—were used to search for articles published from 2000 to 2020 that studied medication adherence in adult Filipino hypertensive population. Out of the initial 1514 articles, 15 articles met the criteria and were included in the analysis. The evidence from the included studies was summarized and discussed in a narrative review using the World Health Organization framework for adherence to long-term therapies as the framework. Result The factors that were positively associated with adherence were health care system-related factors: good patient-health provider relationship, accessibility of health services, use of specialty clinics and programs for hypertension, and health insurance. The factors found to be negatively associated with adherence are (1) social economic factors: younger age, single civil status, low educational attainment, and unemployment; (2) patient-related factors: low in health literacy and awareness, knowledge on hypertension, attitude towards hypertension, self-efficacy, and social support; (3) therapy-related factors: inconsistent drug regimen schedule, use of Thiazide and complementary and alternative medicines; (4) condition-related factors: low illness perception, and absence of comorbidities. Conclusions Findings should be interpreted with caution because of methodological limitations. Despite this, given that health systems related factors are modifiable, they can be the focus of interventions and future researches to increase medication adherence. Clinicians may also want to screen their Filipino hypertensive patients for factors that are associated to low adherence in order to provide a tailored advice. Longitudinal research studies with heterogeneous samples of hypertensive Filipinos are imperative so that targeted interventions can be developed for the population.

Background: Identification of human errors and their related factors in nurses dealing with the health of humans is important. Considering that much workload can increase the risk of human error, this study aimed to investigate the relationship between workload and human errors among nurses working in educational hospitals of Kerman University of Medical Sciences. Methods: This descriptive-analytical study was performed on 145 nurses from educational hospitals affiliated to Kerman University of Medical Sciences in 20. The workload was evaluated using the NASA-TLX questionnaire and human errors with SHERPA technique. The statistical test used was logistic regression model and the statistical significance level was considered <0.05 and the samples were selected randomly. The sample size was selected based on the percentage of functional errors reported by a study on human error assessment related to the duties of nurses in Semnan. Results: A total of 138 probable errors were detected in the nursing staff of these hospitals, 74% of nurses committed errors in seven main duties during their service. Patient medication with the highest frequency (34%) followed by the injection of the drug to the patient with a frequency of 23% were the most frequently committed errors by nurses. The findings of the research showed that workload in 53.1% of the nurses was very high and in 43.1% of the nurses was high, the results of the logistic regression model showed that there was no significant relationship between errors and workload in nurses. Conclusion: The results of the study showed that the average workload and human error in the nurses were high. Therefore, control strategies such as holding training sessions, implementation of clinical governance program in all wards, recruitment of adequate nurses, reduction of workload, reduction of work hours and the appropriate patient/nurse ratio should be given attention by the hospital managers depending on conditions; as well as the prevention of the two reported errors should be given top priority in corrective measures.

Glandonia is a rare genus comprising three species confined to Amazonian rainforest. Glandonia macrocarpa has been documented in some localities of the lower Rio Negro, in the municipality of Manaus, Brazil. Glandonia prancei is represented by only a few herbarium specimens, which were collected along the Madeira and Purus rivers in the 1960s and 70s. A recent record of G. prancei was discovered while analyzing collections of G. macrocarpa, providing a new locality where we found and collected G. prancei. Glandonia williamsii, which had not been recorded in Brazil for the past three decades, was collected in the upper Rio Negro in this study. This work reexamines the taxonomy of the genus, based on fieldwork and herbarium specimens, and includes notes on morpho-anatomy, distribution and phenology. New morpho-anatomical characters are provided to better describe the species (e.g., outline of epidermal cell walls of the leaf, arrangement of petiolar vascular system, bracteole gland surface, and distribution of glands on the leaf blade and petals).
