Current concerns in visual masking.

There is little doubt that the introduction of modern pesticides since the end of the Second World War has enabled a significant increase in the production of many crops during the green revolution, but criticism of the use of pesticides has increased because more people are claiming that their use has resulted in unacceptable adverse impacts on the health of those applying the pesticides or who live near treated farms, as well as more general impacts on the environment. When these modern pesticides were first introduced, countries established registration requirements. These were based on scientific data at that time concerning their toxicity and persistence in the environment, and have been followed to a variable degree, depending on whether individual countries or regions had adequate facilities to assess the data presented by manufacturers.

Current Concerns

Charles Ortloff provides a new perspective on archaeological studies of the urban and agricultural water supply and distribution systems of the major ancient civilizations of South America, the Middle East, and South-East Asia, by using modern computer analysis methods to extract the true hydraulic/hydrological knowledge base available to these peoples. His many new revelations about the capabilities and innovations of ancient water engineers force us to re-evaluate what was known and practised in the hydraulic sciences in ancient times. Given our current concerns about global warming and its effect on economic stability, it is fascinating to observe how some ancient civilizations successfully coped with major climate change events by devising defensive agricultural survival strategies, while others, which did not innovate, failed to survive.

Pedagogical Methods

This study examines how and why 20 instructors (17 tenure-line and 3 nontenure-line) in introductory service courses enact their pedagogical values and address current concerns (e.g., personal branding, LinkedIn, and applicant tracking systems) when teaching résumés and cover letters. Research methods included a demographics survey, qualitative interviews, and critical discourse analysis of assignment sheets and deidentified student examples. Results provide an opportunity to renegotiate gaps between Business and Professional Communication’s research and pedagogical methods, shifting from overemphasizing formatting and checklists and toward understanding job applications as workplace genre ecologies to encourage deeper learning.

Current Concerns

In this work, we present a simple way to achieve 4-arylselanyl-1H-1,2,3-triazoles from selenium-containing carbinols in a one-pot strategy. The selenium-containing carbinols were used as starting materials to produce a range of selanyl-triazoles in moderate to good yields, including a quinoline and Zidovudine derivatives. One-pot protocols are crucial to the current concerns about waste production and solvent consumption, avoiding the isolation and purification steps of the reactive terminal selanylalkynes. We could also isolate an interesting and unprecedented by-product with one alkynylselenium moiety connected to the triazole.

Critical Interest

Abstract A sensitisation to the disciplinary past offers a way forward for sociolinguistic inquiry. Historicisation may add reflexive distance to our current concerns and debates. It may serve to detect, put into perspective and ease epistemological and ideational tensions. It is equally useful for determining the extent to which past ideas and practices linger among us, and for clarifying the effects of such forms of retention. Historicisation may be brought to bear on the ways in which we engage with our objects of study, and on the ways in which we understand our acts of engagement. A critical interest in the disciplinary past could provide a shared historical ground for all strands of sociolinguistic inquiry. It could help us to counteract disciplinary fragmentation, while at the same time stimulate disciplinary renewal and constructive exchange. For these reasons – I argue – a sensitisation to the history of sociolinguistics is of immediate relevance to the readership of the IJSL.
