Greasy spot rind blotch is a serious problem in Florida for the production of grapefruit (Citrus paradisi) for the fresh market. In the 1970s to the early 1980s, the disease was described in detail and the cause was determined to be Mycosphaerella citri, the same species responsible for greasy spot of foliage. The most appropriate timing for fungicide sprays was determined at that time, but peak ascospore release has changed in recent years. In the present study, the relationship of ascospore deposition and fungal growth on fruit was determined in order to more accurately time fungicide applications. Infection of fruit appears to occur similarly to that of leaves: by deposition of ascospores and germination to produce epiphytic growth followed by penetration of the fungus through stomata. Ascospore deposition occurred mostly in May and June, but epiphytic growth began only after the onset of the summer rainy season in June in 2002 and 2003. Ascospore deposition was lower in 2002 than in 2003, but development of epiphytic growth was similar in both years. Timing of fenbuconazole sprays was evaluated in the 2001, 2002, and 2003 seasons. Of the single-spray applications, those in July were the most effective, sprays in June and August were moderately effective, and those made in May or September were ineffective. Two- and three-spray programs from June through August were usually more effective than single sprays, and four monthly sprays from May to August were needed for a high level of control. Fungicide applications are needed about every 3 to 4 weeks after the beginning of the rainy season in June through August for a high level of control of rind blotch.

(BJ6.350)Those who discard their weapons and surrender their persons, I will let live. Like a lenient master in a household, I will punish the incorrigible but preserve the rest for myself.So ends Titus' address to the embattled defenders of Jerusalem in the sixth book of Josephus'Jewish War(6.328-50). It is the most substantial instance of communication between Romans and Jews in the work. Titus compares himself to the master of a household and the Jewish rebels to his slaves. Is this how we expect a Roman to describe empire? If not, what does it mean for our understanding of the politics of Josephus' history? The question is particularly acute given that this is not just any Roman but Titus himself: heir apparent and, if we believe Josephus, the man who read and approved this historical account. It is thus surprising that, while the speeches of Jewish advocates of submission to Rome such as Agrippa II (2.345-401) and Josephus himself (5.362-419) have long fascinated readers, Titus' speech has received little or no attention. Remarkably, it is not mentioned in any of three recent collections of essays on Josephus. This paper aims to highlight the rhetorical choices that Josephus has made in constructing this voice for Titus—particularly his self-presentation as master—and the interpretive questions these raise for his readers. It should go without saying that the relationship of this text to anything that Titus may have said during the siege is highly problematic. (Potentially more significant, but unfortunately no less speculative, is the question of how it might relate to any speech recorded in the commentaries of Vespasian and Titus that Josephus appears to have used as a source.) What we have is a Josephan composition that is embedded in the broader narrative of theJewish War.

AbstractHow can we explain the fact that the Anglican Covenant divides people of equal integrity and comparable wisdom around the world? We need to ask whether we have correctly understood both the ecclesiology of the Anglican Communion and the terms of the Covenant. What is implied in being a Communion of Churches, where the churches are the subjects of the relationship of communion (koinonia)? What does the Covenant commit its signatories to and, in particular, what does it say about doctrinal and ethical criteria for communion? Is it legitimate to apply biblical covenant language, in which the covenant relationship is between God and Israel, to relations between churches? By addressing some of the concerns of those who oppose it, a case is made in favour of the Covenant and some reassurances are offered. In conclusion, the mystical dimension of being in communion is affirmed.

The effort of leptospirosis prevention in Sleman currently only limited to counseling and treatment of the patient, while the patient search, ways of transmission of leptospirosis from rats to humans, have never implemented in an integrated manner. The study aimed to investigated the relationship between the environmental residential condition with the risk of leptospirosis in Sleman Regency. The research used a survey method  with case control study design. The results showed that environmental factors, which are not proved to have a relationship with the risk of leptospirosis were residential condition ({p=0,108} OR=3,818 {95%CI:0,922–15,811}), the trash bin condition ({p=1,000} OR=1,138 {95%CI:0,420–3,081}) and the sewer condition ({p=0,415} OR=0,551 {95%CI:0,187–1,624}). Environmental factors that associated with the risk of leptospirosis was the presence of rats ({p=0,001} OR=13,594 {95%CI:2,754–67,107}). The effort should be made in order to prevent the increasement of Leptospirosis cases by sanitation improvement and avoiding direct contact with rats as well as it litter. The Government should be pay more attention in the vector control programs, especially in leptospirosis prone areas so the prevention effort to be able run effectively and efficiently.

Abstract An intelligent graphical user interface that captures a product’s functional and assembly structure and the factory that will make it are described. The results are then used to evaluate a factory’s production rate for the product. The program requires the product to be either a functionally uncoupled or decoupled design. The interface then: (1) implements a visualization of the functionally decomposed product structure; (2) implements an abstraction of a factory; (3) automatically generates candidate primary manufacturing processes and materials that are compatible with each other based on a very small number of attributes; (4) enables the user to make Make/Buy decisions for the components comprising the product; (5) assists the user in the selection of secondary manufacturing processes that are compatible with the primary manufacturing processes and materials for parts made in-house, and specify the vendor and the supply lead time for outsourced parts; (6) enables the specification of alternate materials and manufacturing processes; (7) implements a visual representation of the assembly structure as specified by the user; and (8) partially automates the creation of the assembly structure, and assists in the selection of assembly methods that are compatible with the materials chosen. In addition, the program assists in the design for assembly by: (1) requiring the product development team to think about the assembly process early in the design stage; (2) providing a visualization of the relationship of all components comprising the product to its other components; (3) requiring the specification of the order in which they are to be assembled; and (4) requiring the selection of assembly processes that are compatible with each other and the materials chosen. It also requires the specification of the capabilities of the factory that is going to make one or more of the components of the product, and requires that Make/Buy decisions for the parts comprising the product be made.

Teachers and researchers have been designing telementoring programs for more than fifteen years, yet there are many possible program designs that have not yet been attempted, and enormous potential yet to fulfill. An attempt is made to map out the “design space” of K-12 telementoring by discussing the major decisions made in designing a telementoring program, and the relationship of these decisions to one another. Where possible, research findings and examples of specific programs are cited in this discussion. By providing a look “under the hood” of telementoring programs, the chapter aims to help teachers become more equal partners in the effort to refine existing programs and develop new ones. Encouragement is offered to researchers to more fully articulate the rationale behind their designs in their writing, and to carry out more research on the efficacy of particular design choices, so that the field can develop cumulative literature on telementoring design.

The chapter opens with some distinctions made in the study of power and semi-formally defines ‘outcome’ and ‘social’ or ‘power to’ and ‘power over’ showing the latter is a subset of the former. It argues both are legitimate ways of examining power. It argues that whilst ‘social power’ is often our concern, especially when discussing issues of freedom, domination and inequality we need to start by considering outcome power. Understanding why people can fail in their aims even when others are not acting against them – failure in their outcome power – is necessary for to understand the scope of social power. The chapter then examines the relationship between outcome power and freedom and discussesMorriss’s distinction between ability and ableness. Power is a dispositional concept and the ability that people have need to be distinguished from their exercise of their powers. It argues that if we only look at abilities we could eliminate the term power from our language since all we would need to is to look at their capacities or resources, but we also need to examine the way that agents change others incentives to act. The chapter introduces the formal aspects of the power index approach and through that discussion distinguishes power and luck. It then introduces bargaining power, formally distinguishes threats and offers and explains Harsanyi’s bargaining model of power and the extra element of reputation. It then discusses the relationship of luck and group power introducing the notion of systematic luck. It then concludes by discussing how we can study power in society.

It is shown that under Tasmanian conditions there is a negative relation between the potassium status of apricot trees and their susceptibility to brown rot. From regression equations calculated, it is suggested that trees with a potassium content of about 4.6 per cent. in oven-dry leaves would be resistant to brown rot. Difficulty was experienced in increasing the potassium content of the trees by soil or spray applications of potassium fertilizer, but when this was achieved, some reduction in brown rot incidence occurred. Regular annual soil dressings of potassium chloride at the rate of 2 lb per tree was the most satisfactory treatment tested.

Abstract Stabilizing certified nursing assistant (CNA) employment is necessary for maintaining care networks and providing high quality of care for nursing home (NH) residents. This study’s objective was to examine the relationship of high wages and empowerment practices on CNA retention. We used the 2015 Ohio Biennial Survey to construct a facility-level dataset of 547 NHs and estimated multivariable linear regressions. NHs that provided both high wages and high empowerment were associated with a 12.95 percentage-point improvement in the CNA retention rate (SE = 4.53, t-value = 2.86, p = 0.0045). High wages and a high empowerment score did not have significant effects individually (p > .05). Retention rates were similar between NHs that lacked high wages and scored low on the empowerment scale, and NHs that provided one at a high level but not the other. Implications for better retaining CNAs require multiple empowerment practices combined with high hourly wages.

This article deals with the study of toponyms of Kazakh and English toponymy in the context of cognitive linguistics and the mechanism of interpretation of representation and perception of color names in toponyms and the principles of construction of these mechanisms. Toponyms are analyzed as a speech expression processed in the consciousness of the linguistic image of the world-the relationship of man and the environment. The modern stage of place names in cognitive research includes the consideration of language as one of the cognitive subsystems and onomastic vocabulary in the formulation of surrounding truths. The composition of the national toponymic picture of the world determines the motivation of the land-water names made in relation to the color names. Studying the combination of onym appellation, nominated from the attributes of the colors used in both languages. The color designation in toponyms is considered in connection with the peculiarities of geographical objects and their perception by human visual organs. Due to the fact that the external world is transmitted to different peoples in the form of specific idioethnic patterns, in place names of different ethnic groups, color symbols are recognized by new facets. The article discusses the color characteristics of the space in the names earth-water, given as a sample. Various approaches to the nature of the color components of geographical names are analyzed, and the possibility of symbolic and orientational interpretation of color is shown. The fact that the color in toponyms can serve as an orientation function, and not just as an indicator of the horizon side, also does not go unnoticed. The toponyms also present the results of research related to the nature of the object in which the symbolism of color orientation is nominated.

The degree to which placebo response is involved in an active treatment situation in normal clinical practice, and the factors comprising the placebo response, have been analyzed in a study on patients with anxiety/depressive syndromes. Four tablet preparations of different appearance but identical pharmacological activity were used over a three week period, and a comparison of therapeutic benefits between ‘treatments', doctors, and doctor—patient groupings was made, in addition to an analysis of the relationship of patients' self-assessments with their physicians' ratings. The results showed that although direct pharmacological effect was paramount in determining therapeutic outcome, detailed differences were related to various placebo factors. The similarity between physicians' and patients' ratings tends to decrease during the course of treatment, and possible reasons for this are reviewed in the light of previous work.
