Abstract Background Phony peach disease (PPD) is caused by the plant pathogenic bacterium Xylella fastidiosa subsp. multiplex (Xfm). Historically, the disease has caused severe yield loss in Georgia and elsewhere in the southeastern United States, with millions of PPD trees being removed from peach orchards over the last century. The disease remains a production constraint, and management options are few. Limited research has been conducted on PPD since the 1980s, but the advent of new technologies offers the opportunity for new, foundational research to form a basis for informed management of PPD in the U.S. Furthermore, considering the global threat of Xylella to many plant species, preventing import of Xfm to other regions, particularly where peach is grown, should be considered an important phytosanitary endeavor. Main topics We review PPD, its history and impact on peach production, and the eradication efforts that were conducted for 42 years. Additionally, we review the current knowledge of the pathogen, Xfm, and how that knowledge relates to our understanding of the peach—Xylella pathosystem, including the epidemiology of the disease and consideration of the vectors. Methods used to detect the pathogen in peach are discussed, and ramifications of detection in relation to management and control of PPD are considered. Control options for PPD are limited. Our current knowledge of the pathogen diversity and disease epidemiology are described, and based on this, some potential areas for future research are also considered. Conclusion There is a lack of recent foundational research on PPD and the associated strain of Xfm. More research is needed to reduce the impact of this pathogen on peach production in the southeastern U.S., and, should it spread internationally, wherever peaches are grown.

Whip smut of sugarcane is the most serious and widely spread disease of sugarcane and causes a significant reduction in cane quantity and quality. The severity of this disease often depends on the pathogen races, environmental conditions, cultivar genotype and the interaction among these three factors. Under optimum climatic conditions, this disease has the potential to cause total crop failure. Resistance screening is an ongoing process due to the variability among smut pathogen isolates. Multiple races and mutation ability of smut pathogen makes the breeding task more complex. A number of studies on various aspects of the disease epidemiology and management have been published. Due to many overlapping characteristics within the species complex, there is a dearth of information on early detection and strategies to control the smut pathogen. Furthermore, there is a need to coordinate these findings to expedite its research and control. In this paper, we summarize the disease etiology, especially disease impact on the qualitative and quantitative parameters of sugarcane. We also gathered research progress on molecular-based detection and available information on genetic variability in S. scitamineum. The research on the set of management options needed to effectively cope with the disease are reviewed herein. The present review is expected to be helpful for the further investigation on smut resistance in sugarcane.

The Impact

The COVID-19 pandemic represents a global threat and crisis situation, and its wide-reaching impact has also affected marital satisfaction. Dysfunction of the marital system puts the survival of the family unit at risk. This research aimed to determine the level of marital satisfaction of Portuguese families during the social lockdown and the association between the variables under study. A descriptive, exploratory study was conducted. During the social lockdown, 276 people of Portuguese nationality and residing in Portugal were recruited using nonprobabilistic convenience sampling. Marital satisfaction in the pandemic phase showed low values that may be associated with the social, economic, and political context experienced by the pandemic situation. Future research must be carried out in order to identify, prevent, and intervene in situations of violence. In addition, future research should explore not only marital satisfaction during the current pandemic but a more systemic assessment of marital relations during crises, expanding the impact of marital satisfaction in family functioning.

Purpose The purpose of the paper is to present the latest scholarly trends in the field of social capital in libraries, to review research concepts published by LIS professionals and to suggest further research possibilities in this area. Design/methodology/approach This paper presents a review and critical analysis of literature associated with research on social capital in libraries to highlight its importance for the development of LIS and its impact on the functioning of environments linked with various types of libraries. The goal of literature analysis was to determine the current condition of research on social capital in libraries. The main trends were identified and the need for further qualitative analyses, which are missing at the moment, was confirmed. Findings It was determined that, so far, LIS professionals have focussed mainly on the role of municipal libraries in developing social capital, the problem of building trust, especially in immigrant circles and the impact of libraries on promoting a civil society. Academic libraries, rural libraries, organisational capital in libraries and individual social capital of librarians were a much less frequent subject of research. The role of libraries in developing social capital in educational (primary and secondary education) and professional (non-university professionals) circles is practically non-existent in research, and it will require in-depth studies and analyses in the coming years. Originality/value This paper constitutes a synthetic review of the latest research concepts concerning social capital in libraries. It identifies the most important research trends and areas that so far have not been explored and suggests research methods to help LIS professionals design future research in this area more effectively.

Abstract Conspecific presence can indicate the location or quality of resources, and animals settling near conspecifics often gain fitness benefits. This can result in adaptive conspecific attraction during breeding habitat selection as demonstrated in numerous terrestrial, territorial birds. There is growing interest in using simulated conspecific social cues (e.g., decoys, broadcasted vocalizations) to manage bird distributions, yet it remains unclear when this approach is likely to succeed. We reviewed published studies to evaluate whether the strength of conspecific attraction in terrestrial birds is mediated by characteristics of species (life history traits), simulated cues (e.g., timing and duration), sites (e.g., quality), and how conspecific attraction was measured. We identified 31 experiments that simulated social cues and compared conspecific settlement between treatment and control sites. We then used phylogenetically controlled meta-regression to assess the impacts of 19 moderators on settlement. Nearly all species included in these experiments were migratory passerines, and social cues generally had a strong, positive influence on their settlement decisions, as the odds of site occupancy were 3.12× (95% CI: 0.81–11.69) greater in treatment sites relative to control sites. Within this group, conspecific attraction was evolutionarily conserved with ≥25.5% (95% CI: 5.1%–65.4%) of the variance in treatment effects explained by phylogenetic relatedness. However, we found no evidence that any covariates influenced the response to social cues, and we posit this stems from limited research specifically designed to identify the mechanisms mediating conspecific attraction. We therefore developed a research agenda that provides a framework for testing mechanistic hypotheses regarding how cue characteristics, species traits, and spatial contexts may mediate attraction to conspecifics. Evaluating these hypotheses will greatly advance the field by helping managers understand when, where, and why simulating social cues can be used to enhance populations of species that are of conservation concern.

This chapter explores our current knowledge of pathology and trauma in Romano-British non-adult samples focusing on the children from the late Roman cemetery of Poundbury Camp, Dorset. Evidence for metabolic diseases (rickets, scurvy, iron deficiency anaemia), fractures, thalassemia, congenital disorders and tuberculosis, are presented with emphasis on what their presence tells us about the impact of the Romans in Britain. Many of the large Roman sites from the UK were excavated long before diagnostic criteria for recognizing pathology in child remains were fully developed, and European studies tend only to focus on anaemia and its link to malaria. A lack of environmental evidence for the sites from which our skeletal remains are derived is also problematic, and this chapter hopes to set the agenda for future research into the health and life of children living in the Roman World.

And Training

In 2010, the Arizona legislature effectively deregulated concealed handgun carry in the state by passing Senate Bill (SB) 1108, which eliminated licensing and training requirements for concealed carry. Although researchers have extensively examined the impact of state adoption of concealed carry laws, almost nothing is known about the effects of deregulating concealed carry altogether. This study contributes to the more guns, less crime debate by examining the impact of Arizona’s decision to deregulate concealed carry. Using a multiple time-series research design with an experimental (Tucson) and control city (El Paso), the present study examines the impact of deregulation on handgun-related violent crime and gun larcenies in Arizona’s second largest city—Tucson. We find that the passage of SB 1108 had no impact on handgun-related offenses that could be expected to change following deregulation. The implications of these findings for policy making and future research are discussed.

Employees are major assets of every organization. The accomplishment of the industry depends on its employee performance. Therefore, upper management knows the significance of expense in training for the advantage of improving employee performance and also places them to get the challenges of the today’s competitive business environment. This research also aims to see the “Impact of Training on Employee Performance in Pharmaceutical Industry in Karachi Pakistan”, in which Training consider as independent whereas dependent variable ‘Employee Performance‘ having its Performance areas i.e.; demonstrating team work, communication skill, customer service, interpersonal relationship and reduced absenteeism and its Developments areas i.e.; job-satisfaction, employee motivation, new technologies, efficiencies in process and innovation in strategies as its levers. The paper presents a concise summary of the literature on the value of training in improving the performance of the employees. Four pharmaceutical companies are selected. A survey of 356 employees via self administrated questionnaire with the help of random sampling technique is conducted with the response rate of 96%. Two sets of hypothesis are developed which relate directly to the research questions. SPSS 19 is used to perform reliability, descriptive, correlation and regression analysis. The analysis shows a positive significant relationship between them and the results reveal that the more the employee gets training, the more efficient their level of performance would be. The last section of the paper concludes along with recommendation to give guidelines for future research.

Review Current

The endometrium is a multicellular tissue that is exquisitely responsive to the ovarian hormones. The local mechanisms of endometrial regulation to ensure optimal function are less well characterised. Transient physiological hypoxia has been proposed as a critical regulator of endometrial function. Herein, we review the literature on hypoxia in the non-pregnant endometrium. We discuss the pros and cons of animal models, human laboratory studies and novel in vivo imaging for the study of endometrial hypoxia. These research tools provide mounting evidence of a transient hypoxic episode in the menstrual endometrium and suggest that endometrial hypoxia may be present at the time of implantation. This local hypoxia may modify the inflammatory environment, influence vascular remodelling and modulate endometrial proliferation to optimise endometrial function. Finally, we review current knowledge of the impact of this hypoxia on endometrial pathologies, with a focus on abnormal uterine bleeding. Throughout the manuscript areas for future research are highlighted with the aim of concentrating research efforts to maximise future benefits for women and society.

Purpose This paper aims to gain an in-depth understanding of how the internal audit function evolves in an increasingly digitalised business environment. Design/methodology/approach This paper is based on 29 semi-structured interviews with members of management committees and internal auditors based in Belgium. Findings The analysis reveals that a digitalised business environment affects the internal audit function in three respects. First, it impacts its scope. The agility of the internal audit planning and the required digital knowledge are expected to increase and information technology (IT) risks gain importance, especially cybersecurity threats. Second, the demand for consulting activities performed by internal auditors is higher and third, digitalisation modifies the working practices of internal auditors in their day-to-day tasks. New technologies such as data analytics tools are being implemented progressively in internal audit departments and digital skills are considered a critical asset. Research limitations/implications This research was conducted in the European Union and gathers opinions of members of management committees and internal auditors. Future research could focus on other internal auditing stakeholders in other legal contexts. Practical implications The internal audit function needs to integrate IT and data analytics skills. In addition, the internal audit function should develop consulting activities to help organisations deal with the digitalisation of the business environment. Originality/value The impact of digitalisation on the internal audit function and its effect on internal audit practices is an underexplored area.
