Research Notes : Soybean linkage and crossover tests

A previous test (Buzzell, 1977) indicated a possible linkage (39.8 .±. 3.0%) between Fg1 and Dt1. An additional test with F2 plants of a cross of two \u27Harosoy\u27 isolines (fg1 dt1 x Fg1 Dt1) indicates that the two genes are independent (Table 1). In reporting on the genetics of flavonol classes 9T to 16T, Buzzell and Ruttery (1974) indicated that the 9t to 16t classes which involve fg4t had not been observed

Research Notes : Canada : Preliminary information on the Rps allele in the cultivar Harosoy

The \u27Harosoy\u27 soybean cultivar was considered to be the universal suscept for Phytophthora megasperma f. sp. glycinea when it was included in the differential host series for this pathogen (Haas and Buzzell, 1976). However, Moots (1982) reported that an Rps allele pair was present in Harosoy that conferred resistance to races 12 and 16. Harosoy is also resistant to races 18 and 19 but is susceptible to all other races 1-25 (unpublished results)

Research Notes : Inheritance of insensitivity to long daylength

Genetic tests for daylength insensitivity have been run using PI 297,550 reported to be day-neutral by Polson (1972), as source material. Segregating material was grown under long days at various times from 1973 to 1979, either in a growth cabinet (Buzzell et al., 1974) or in a greenhouse with daylength 27 extended to 20 hours with incandescent light. Material was classified at 35 to 42 days after planting as either non-flowering, sensitive (S), or flowering, insensitive (I)

Exploring the impact of an evolving war and terror blogosphere on traditional media coverage of conflict

This article analyses the evolution of a war and terror blogosphere between 2001 and 2011. It identifies seven areas where blogs and related online genres could provide ‘alternative’ accounts to traditional media narratives of conflict. The article also assesses the challenges and opportunities of blogs in each area from the perspective of the working journalist in order to deepen our understanding of the changing influence of blogs on traditional media narratives of conflict. Parallel accounts and interpretations of conflict will collaborate and compete in a war and terror blogosphere in the future, but it has been significantly influenced by the adoption of blogging by military actors since 2008. The war and terror blogosphere is no longer a relatively unmonitored online space which is having an impact on both the production of ‘alternative’ accounts of conflict and the incorporation of these accounts into traditional journalism

Spinal Cord

STUDY DESIGN: Observational, population-based cohort study. OBJECTIVES: To evaluate the origin and contribution to excess of survival differences following non-traumatic spinal cord injury (NTSCI) using etiology as proxy for variation in underlying health condition. SETTING: Specialized rehabilitation centers in Switzerland. METHODS: Medical record data collected by the Swiss Spinal Cord Injury cohort (SwiSCI) study were linked with mortality information from the Swiss National Cohort. Considering contemporary theory and empirical evidence, a directed acyclic graph (DAG) was developed to formally evaluate causal differences among NTSCI etiologies, relative to traumatic SCI (TSCI). Statistical inference was contingent on hazard ratios (HRs) and marginal survival differences, derived using flexible parametric modeling. RESULTS: 3643 individuals (NTSCI = 1357; TSCI = 2286) diagnosed with SCI between 1990 and 2011 were included, contributing a cumulative 41,344 person-years and 1323 deaths. Test statistics confirmed DAG-dataset consistency. As compared to TSCI, mortality was elevated in all NTSCI etiological groups; malignant etiologies had the highest HRs (10; 95% CI, 8.0 to 14) followed by infection (2.6; 1.8 to 3.6) and vascular (2.5; 2.0 to 3.2) etiology groups. At the attained age of 55, the estimated reduction in survival among non-malignant etiologies was 9.4% (5.8 to 13) at 5 years and 17% (11 to 23) at 20 years. CONCLUSIONS: Causal differences in survival among NTSCI etiological groups are likely a result of chronic variation in health conditions. This study supports the development of long-term interdisciplinary management and policy for individuals with NTSCI, specific to etiology

Excess burden of a chronic disabling condition: life lost due to traumatic spinal cord injury in a Swiss population-based cohort study.

OBJECTIVES To estimate excess mortality and life years lost in a Swiss cohort of individuals with traumatic spinal cord injury (TSCI). METHODS This study uses population-based data collected in the Swiss Spinal Cord Injury Cohort (SwiSCI) study, which covers all specialized rehabilitation centres. Flexible parametric survival models were used to model life years remaining (LYR), potential years life lost (PYLL), relative survival and excess hazard ratios. RESULTS Men and women with TSCI and an attained age of 30 were estimated to have 42 LYR (95% CI = 37.9-45.5) and 43 LYR (95% CI = 40.1-45.5), respectively; this equates to a life expectancy (LE) of 80.6 and 76.9% of that of the Swiss general population. With respect to lesion level and completeness, persons with incomplete paraplegia had 45.1 LYR at an attained age of 30, whereas individuals with complete tetraplegia only had 28.7 LYR. This pattern was similar for PYLL. CONCLUSIONS The extended LE following TSCI, even for the most severe lesions, underscores the need for sustained follow-up to support functioning and health for individuals ageing with SCI

How to Develop Strategic Management Competency: Reconsidering the Learning Goals and Knowledge Requirements of the Core Strategy Course

The dominance of theory-based approaches to strategy teaching has not displaced the need for core courses in strategic management to cultivate broader management skills. Yet, limited attention has been given to explicating, first, why we need to teach these skills, second, which skills we need to teach, and third how they can to be developed in the classroom. To help answer these three questions we need to understand the linkages between theory-based and skills-based approaches to strategy teaching. We begin with the proposition that the purpose of the core strategic management is to develop the strategic management competency of our students. We then adopt a systematic approach to identifying the why, what, and how components of strategic management competency. We show why analytical tools need to be complemented by judgment, insight, intuition, creativity, and social and communicative skills. We outline what these skills are and where they come from. Finally, we derive implications for how we should design and deliver of the core strategic management course
