Genetic Variation in Resistance of Scotch Pine to Zimmerman Pine Moth

(excerpt) Scotch pine (Pinus sylvestris L.), a forest tree introduced from Eurasia, is commonly planted for Christmas tree and timber use in northeastern United States. In this country it has numerous insect enemies. Among the most important are European pine shoot moth, Rhyacionia buoliana (Schiffermiieller); pine root collar weevil, Hylobius radicis Buchanan;,European pine sawfly, Neodiprion sertifer (Geoffroy); and eastern white-pine shoot borer, Eucosma gloriola Heinrich. Previous studies (Wright et al., 1967; Wright and Wilson, 1972; Steiner, 1974) have revealed large genetic differences in resistance to some of these pests. Another destructive pest is the Zimmerman pine moth, Dioryctria zimmermani (Grote). In 1968 this insect, native to the United States, was found attacking trees in a Scotch pine provenance test in southwestern Michigan. The attack rate was heavy and by 1973 it was obvious that some rams or varieties were attacked more heavily than others. This is a report on those differences

Range Extension of \u3ci\u3eStylogomphus Albistylus\u3c/i\u3e (Odonata: Gomphidae) for the Upper Peninsula of Michigan

Larvae, exuviae, and teneral adults of Stylogomphus albistylus (Hagen) were collected from Mountain Stream, within the boundaries of the Huron Mountain Club, in the Upper Peninsula of Michigan (Marquette County). This represents the first published report of this species from the Upper Peninsula of Michigan, and only the second recorded site for the state of Michigan

Pastoral stock water workbook

The Pastoral Stock Water Workbook has been developed to assist you to estimate the costs of maintaining stock water and make informed decisions about managing existing and proposed water points. The first half of the Workbook provides background information on stock water points, their usage, advantages and disadvantages. Whilst the second part contains a series of stepby- step exercises that should be completed as you progress through the Workbook. The latter part of the Workbook aims to: • Show a worked example of the annual costs of maintaining water; • Provide tools to calculate water costs for your business; • Outline how to use this information to plan for future management; and • Assist you to make water point decisions that increases your business\u27 efficiency

Evidence Of Global Warming In Nigeria

The paper shows evidence of global warming in Nigeria with special consideration on temperature; both maximum and minimum, rainfall, relative humidity and speed of wind. In the study, descriptive statistics were used which include mean, standard error, and variance. For the test of significant variation in the factors considered, One-Way Analysis of Variance was used. The tool is one of the parameteric tools in Statistics which implies it has underline assumptions. All the assumptions associated with the Statistical tool were tested using the most appropriate technique. The modeling of temperature and rainfall in the region was done using linear regression approach. The study reveals that temperature of the region has increased in recent time with significant increase in volume of rainfall. The observations and the future values of environmental factors considered is an implication of existence of global warming in the eastern part of Nigeria

Social Media and News Gathering: Tapping into the Millennial Mindset

Social media are transforming the way information travels within and between networks of individuals. Many pundits claim that individuals no longer seek news but instead news finds individuals, particularly on social media websites. The current study is an exploratory look at how one specific group of individuals—Gen Y—gathers news. Data was collected from an online survey and results indicate that Gen Y is increasingly relying on social media for information and news. Interestingly, despite their preference of social media for news gathering, young adults still perceive traditional media sources as more credible than social media sources. Other findings are presented, and both theoretical and practical implications are drawn.

Increasing the intensity and comprehensiveness of aphasia services: identification of key factors influencing implementation across six countries

Background: Aphasia services are currently faced by increasing evidence for therapy of greater intensity and comprehensiveness. Intensive Comprehensive Aphasia Programs (ICAPs) combine these elements in an evidence-based, time-limited group program. The incorporation of new service delivery models in routine clinical practice is, however, likely to pose challenges for both the service provider and administering clinicians. This program of research aims to identify these challenges from the perspective of aphasia clinicians from six countries and will seek to trial potential solutions. Continual advancements in global communication technologies suggest that solutions will be easily shared and accessed across multiple countries. Aims: To identify the perceived and experienced barriers and facilitators to the implementation of 1) intensive aphasia services, 2) comprehensive aphasia services, and 3) ICAPs, from aphasia clinicians across six countries. Methods and procedures: A qualitative enquiry approach included data from six focus groups (n = 34 participants) in Australia, New Zealand, Canada, United States of America (USA), United Kingdom (UK), and Ireland. A thematic analysis of focus group data was informed by the Theoretical Domains Framework (TDF). Outcomes and results: Five prominent theoretical domains from the TDF influenced the implementation of all three aphasia service types across participating countries: environmental context and resources, beliefs about consequences, social/professional role and identity, skills, and knowledge. Four overarching themes assisted the identification and explanation of the key barriers and facilitators: 1. Collaboration, joint initiatives and partnerships, 2. Advocacy, the promotion of aphasia services and evidence-based practice, 3. Innovation, the ability to problem solve challenges, and 4. Culture, the influence of underlying values. Conclusions: The results of this study will inform the development of a theoretically informed intervention to improve health services’ adherence to aphasia best practice recommendations

The Management of Technology Transfer Plenary Paper

The future world economic development as well as the improvement of other aspects of the quality of life depends to a very large extent on technological development, which again depends essentially on the successful application of the process of technological innovation. This process with its various stages of research, development, engineering, and marketing cannot function without effective communication for the purpose of technology transfer, i.e., transferring knowledge between the stages.It is important not only to understand the process of technological innovation and to realize that technology transfer is an essential part of it, but also to understand that technology transfer is the transferring of knowledge rather than of goods and services, and is dependent on successful communication. Further, technology transfer should be managed as part of the package of managing technological innovation, which should be purposeful and continuous rather than a response to haphazard demands.One of the aims of the National Timber Research Institute is to promote the more efficient use of the South African wood resource as a reliable and economical structural material. Research results in this field have been successfully transferred to the South African forest products industry where 90 low cost stress-grading machines are now in use, and where stress-graded timber is selectively used in glulam products and 20% of all roof trusses.The low cost grading machine, the grading system, the design data, the roof truss design method and computer program, as well as the glulam manufacturing systems, were developed by the National Timber Research Institute and transferred to industry by way of research steering committees, symposia, publications, industry-sponsored development contracts, and direct assistance in factories

The Distribution of the Inverse Square Root Transformed Error Component of the Multiplicative Time Series Model

The probability density function, mean and variance of the inverse square-root transformed left-truncated N(1,σ2) error component e*t(=1/ √et) of the multiplicative time series model were established. A comparison of key-statistical properties of e*t and et confirmed normality with mean 1 but with Var(e*t) ≈1/4Var(et) when σ≤0.14. Hence σ≤0.14 is the required condition for successful transformation
