WOMEN AND SECONDARY SCHOOL PRINCIPAL ROTATION/SUCCESSION: A STUDY OF THE BELIEFS OF DECISION MAKERS IN FOUR PROVINCES

Our study investigated patterns of female participation as secondary principals that have varied across contexts and changed slowly. Researchers interviewed decision makers from a purposive sample of 10 urban and rural school districts in Ontario, Nova Scotia, Saskatchewan, and British Columbia, gathering data from structured telephone interviews, policy documents, and statistical information. The needs of a system took precedence over those of individuals. Many participants denied that gender influenced their rotation/succession practices; however, they identified differences by gender in leadership style and aspirations. Complex rules of control affected the participation of women as secondary principals. Gender clearly affects the participation of women as secondary school principals.Key words: gender, leadership, schools Les auteurs analysent les modes de participation de directrices d’école secondaire, lesquels varient d’un contexte à l’autre et changent lentement. Ils ont interviewé des décideuses provenant d’un échantillon choisi à dessein de dix arrondissements scolaires urbains et ruraux en Ontario, en Nouvelle‐Écosse, en Saskatchewan et en Colombie‐Britannique. Les données furent colligées au moyen d’entrevues téléphoniques structurées, le tout complété par l’analyse de documents de politiques et de renseignements statistiques. Leurs conclusions semblent indiquer que les besoins du système l’emportent sur les besoins de la personne. Un grand nombre des répondantes contestaient l’idée que le fait d’être un homme ou une femme exerce une influence sur les méthodes de rotation/succession ; elles notaient par contre des différences selon les sexes pour ce qui est du style de leadership, des orientations et des aspirations. Des règles complexes de contrôle affectent la participation des femmes à titre de directrices d’école secondaire. Le sexe affecte clairement la participation des femmes en tant que directrices d’école secondaire. Mots clés : genre, leadership, écoles

Beef focus group: Challenges facing the sector

The Simpson Centre initiated a focus group for agricultural industry stakeholders specifically in the Canadian beef sector to gauge their opinions on the current interaction of this sector with policy, the challenges that are specific to this sector, and their short-term and long-term priorities. The majority of concerns and frustrations that were voiced by participants involved a lack of parity and revenue flow between the various aspects of the beef industry, as well as a lack of accurate representation and industry knowledge by policy makers, which many believed had resulted in an abundance of red tape. Nearly all participants spoke to specific challenges they face within the sector that included the cold climate within Canada that makes it harder to compete on an international level and maintain the daily tasks of a producer, as well as challenges facing the longevity of the industry in Canada and incentivizing younger generations to join the sector. &nbsp

Evolution of a TRIM5-CypA Splice Isoform in Old World Monkeys

The TRIM family proteins share a conserved arrangement of three adjacent domains, an N-terminal RING domain, followed by one or two B-boxes and a coiled-coil, which constitutes the tripartite-motif for which the family is named. However, the C-termini of TRIM proteins vary, and include at least nine evolutionarily distinct, unrelated protein domains. Antiviral restriction factor TRIM5α has a C-terminal B30.2/SPRY domain, which is the major determinant of viral target specificity. Here, we describe the evolution of a cyclophilin-A encoding exon downstream of the TRIM5 locus of Asian macaques. Alternative splicing gives rise to chimeric transcripts encoding the TRIM motif fused to a C-terminal CypA domain (TRIM5-CypA). We detected TRIM5-CypA chimeric transcripts in primary lymphocytes from two macaque species. These were derived in part from a CypA pseudogene in the TRIM5 locus, which is distinct from the previously described CypA insertion in TRIM5 of owl monkeys. The CypA insertion is linked to a mutation in the 3′ splice site upstream of exon 7, which may prevent or reduce expression of the α-isoform. All pig-tailed macaques (M. nemestrina) screened were homozygous for the CypA insertion. In contrast, the CypA-containing allele was present in 17% (17/101) of rhesus macaques (M. mulatta). The block to HIV-1 infection in lymphocytes from animals bearing the TRIM5-CypA allele was weaker than that in cells from wild type animals. HIV-1 infectivity remained significantly lower than SIV infectivity, but was not rescued by treatment with cyclosporine A. Thus, unlike owl monkey TRIMCyp, expression of the macaque TRIM5-CypA isoform does not result in increased restriction of HIV-1. Despite its distinct evolutionary origin, Macaca TRIM5-CypA has a similar domain arrangement and shares ∼80% amino-acid identity with the TRIMCyp protein of owl monkeys. The independent appearance of TRIM5-CypA chimeras in two primate lineages constitutes a remarkable example of convergent evolution. Based on the presence of the CypA insertion in separate macaque lineages, and its absence from sooty mangabeys, we estimate that the Macaca TRIM5-CypA variant appeared 5–10 million years ago in a common ancestor of the Asian macaques. Whether the formation of novel genes through alternative splicing has played a wider role in the evolution of the TRIM family remains to be investigated

tRNAs: Cellular Barcodes for Amino Acids

The role of tRNA in translating the genetic code has received considerable attention over the last 50 years, and we now know in great detail how particular amino acids are specifically selected and brought to the ribosome in response to the corresponding mRNA codon. Over the same period, it has also become increasingly clear that the ribosome is not the only destination to which tRNAs deliver amino acids, with processes ranging from lipid modification to antibiotic biosynthesis all using aminoacyl‐tRNAs as substrates. Here we review examples of alternative functions for tRNA beyond translation, which together suggest that the role of tRNA is to deliver amino acids for a variety of processes that includes, but is not limited to, protein synthesis

Hyperspectral reflectance as a tool to measure biochemical and physiological traits in wheat

Simultaneous indirect assessment of multiple and diverse plant parameters in an exact and expeditious manner is becoming imperative in irrigated arid regions, with a view toward creating drought-tolerant genotypes or for the management of precision irrigation. This study aimed to evaluate whether spectral reflectance indices (SRIs) in three parts of the electromagnetic spectrum ((visible-infrared (VIS), near-infrared (NIR)), and shortwave-infrared (SWIR)) could be used to track changes in morphophysiological parameters of wheat cultivars exposed to 1.00, 0.75, and 0.50 of the estimated evapotranspiration (ETc). Significant differences were found in the parameters of growth and photosynthetic efficiency, and canopy spectral reflectance among the three cultivars subjected to different irrigation rates. All parameters were highly and significantly correlated with each other particularly under the 0.50 ETc treatment. The VIS/VIS- and NIR/VIS-based indices were sufficient and suitable for assessing the growth and photosynthetic properties of wheat cultivars similar to those indices based on NIR/NIR, SWIR/NIR, or SWIR/SWIR. Almost all tested SRIs proved to assess growth and photosynthetic parameters, including transpiration rate, more efficiently when regressions were analyzed for each water irrigation rate individually. This study, the type of which has rarely been conducted in irrigated arid regions, indicates that spectral reflectance data can be used as a rapid and non-destructive alternative method for assessment of the growth and photosynthetic efficiency of wheat under a range of water irrigation rates.This work was supported by the Sustainable Modernization of Traditional Agriculture (MasAgro) initiative from the Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA) and a collaboration between CIMMYT, CSIRO and The Australian National University.

Seedbank Persistence of Palmer Amaranth (\u3ci\u3eAmaranthus palmeri\u3c/i\u3e) and Waterhemp (\u3ci\u3eAmaranthus tuberculatus\u3c/i\u3e) across Diverse Geographical Regions in the United States

Knowledge of the effects of burial depth and burial duration on seed viability and, consequently, seedbank persistence of Palmer amaranth (Amaranthus palmeri S. Watson) and waterhemp [Amaranthus tuberculatus (Moq.) J. D. Sauer] ecotypes can be used for the development of efficient weed management programs. This is of particular interest, given the great fecundity of both species and, consequently, their high seedbank replenishment potential. Seeds of both species collected from five different locations across the United States were investigated in seven states (sites) with different soil and climatic conditions. Seeds were placed at two depths (0 and 15cm) for 3 yr. Each year, seeds were retrieved, and seed damage (shrunken, malformed, or broken) plus losses (deteriorated and futile germination) and viability were evaluated. Greater seed damage plus loss averaged across seed origin, burial depth, and year was recorded for lots tested at Illinois (51.3% and 51.8%) followed by Tennessee (40.5% and 45.1%) and Missouri (39.2% and 42%) for A. palmeri and A. tuberculatus, respectively. The site differences for seed persistence were probably due to higher volumetric water content at these sites. Rates of seed demise were directly proportional to burial depth (α=0.001), whereas the percentage of viable seeds recovered after 36 mo on the soil surface ranged from 4.1% to 4.3% compared with 5% to 5.3% at the 15-cm depth for A. palmeri and A. tuberculatus, respectively. Seed viability loss was greater in the seeds placed on the soil surface compared with the buried seeds. The greatest influences on seed viability were burial conditions and time and site-specific soil conditions, more so than geographical location. Thus, management of these weed species should focus on reducing seed shattering, enhancing seed removal from the soil surface, or adjusting tillage systems

Physical Fitness and Depressive Symptoms during Army Basic Combat Training

Mental health-related problems are a significant cause of attrition during Basic Combat Training (BCT). Evidence in civilian populations suggests that physical fitness is associated with psychological benefits in civilians, but little is known about the association between physical fitness and psychological adjustment during BCT

Implementing The Prison Rape Elimination Act: A Toolkit for Jails

Minor edits. “The goal of this Toolkit is to provide jails of all sizes, political divisions, and geographic locations with a step-by-step guide for preventing, detecting, and eliminating sexual abuse of inmates in their custody – and for responding effectively to abuse when it occurs. Prison rape includes all forms of inmate sexual abuse within a correctional facility, including state and federal prisons, county and municipal jails, police lock-ups, holding facilities, inmate transportation vehicles, juvenile detention facilities, and community corrections facilities. Protecting arrestees, detainees, and inmates from sexual violence is part of a jail’s core mission. This toolkit will help assess your jail’s operations with an eye to improvements.” The Toolkit is divided into folders holding materials related to: introductory information about PREA [Prison Rape Elimination Act] and it Standards; a Self-Assessment Checklist with supporting forms “to provide a step-by-step process for jails to review and assess policies, procedures, and practices in light of the PREA Standards and accepted best practices”; and additional resources to assist you in PREA-readiness
