Abstract Field studies were conducted in 2005 and 2006 in south Texas and the southern High Plains of Texas to determine peanut response to POST applications of chlorimuron at 9 g ha−1. Treatments included chlorimuron alone, imazethapyr applied 21 days after planting (DAP) followed by chlorimuron applied POST, and chlorimuron plus either 2,4-DB or chlorothalonil in combination applied POST. Postemergence herbicide applications were made 60, 74, and 88 DAP at the southern High Plains location or 67, 81, or 95 DAP at the south Texas location. No difference in peanut stunting was observed with any chlorimuron treatments at the south Texas location. At the High Plains location, chlorimuron alone, imazethapyr followed by chlorimuron, and chlorimuron in combination with 2,4-DB stunting was greater than chlorimuron in combination with chlorothalonil in one of two years. Imazethapyr followed by chlorimuron reduced peanut yield in one year in south Texas. No peanut grade (sound mature kernels plus sound splits) differences between chlorimuron treatments were noted at the south Texas location, but for the southern High Plains location, peanut grade was greater when peanut was treated with imazethapyr followed by chlorimuron compared to the other chlorimuron treatments.

This chapter presents a sermon by Maurice N. Eisendrath, delivered on the third Rosh Hashanah of the war. The situation of Canadian rabbis was precariously positioned between those of American preachers to the south and British preachers to the east. Canada, as part of the British Commonwealth, had long been part of the war effort, so the debate over whether or not to enter the war was not an issue, as it still was for colleagues in the United States. On the other hand, Canada was not directly affected by the war as was Britain, where one year earlier London had suffered a sustained air attack unprecedented in its devastation (a situation that certainly affected the mood in Toronto on the previous Rosh Hashanah, as the preacher reminds his listeners). Now, although the battles on the recently opened Eastern Front were of almost unimaginable ferocity, to many Canadians the war seemed distant; life at home seemed almost normal, as it did to many in the United States. This was precisely the mindset that Eisendrath set out to censure.

Field studies were conducted in different peanut-growing areas of Texas during the 1999 through 2001 growing seasons to evaluate yellow nutsedge control and peanut tolerance to diclosulam alone applied PRE,S-metolachlor alone applied POST, or diclosulam applied PRE followed by (fb)S-metolachlor applied POST. Yellow nutsedge control was > 80% at five of six locations when diclosulam at 0.018 or 0.026 kg/ha applied PRE was fbS-metolachlor applied POST at 0.56, 1.12, or 1.46 kg ai/ha. Peanut stunting was noted with diclosulam at the High Plains locations but not at the Rolling Plains or south Texas locations. This stunting with diclosulam was due to a combination of peanut variety and high soil pH. Peanut yield was not always increased where yellow nutsedge was controlled.

The eastern escarpment of the Southern High Plains (USA) is today a semi-arid erosional landscape delineated by canyon breaks and topographic relief. A series of buried soils were identified, described, and sampled at 19 soil profile localities exposed along terraces of the South Fork of the Double Mountain Fork of the Brazos River (South Fork) and two associated tributaries (Spring Creek and Macy 285 drainage). Radiocarbon dating revealed late-Pleistocene to early Holocene (~12,580–9100 14C B.P.), middle-Holocene (~6025–4600 14C B.P.), and late-Holocene (~2000–800 14C B.P.) buried soils. The late-Pleistocene to middle-Holocene soils were preserved only at higher elevations within the upper section of the South Fork and Spring Creek. A topographic position analysis was conducted using GIS to identify and examine the impacts of a soil topographic threshold on the preservation and distribution of buried soils within this geomorphic system. Above the identified ~810 m threshold, lateral migration of channels was constrained. Extensive channel migration below the threshold removed older terraces that were replaced with late-Holocene terraces and associated buried soils. Landscape topography constraints on geomorphic processes and soil formation impacted the preservation of archaeological sites in this semi-arid region.

Field studies were conducted in south and the High Plains of Texas as well as in southwestern Oklahoma during the 2014 and 2015 growing seasons to evaluate the effects of glyphosate plus dicamba combinations (1/16 X to 1 X of the 1.68 kg ae ha-1 rate) applied 30, 60, and 90 days after planting (DAP) on Spanish (Oklahoma) and runner (Texas) peanut.  Rates were established to evaluate sub-labeled drift and direct application of a 1 X rate.  Peanut stunting and death were more prevalent at the 30 and 60 DAP application while peanut were more tolerant of the 90 DAP application.  In south Texas, peanut yields were reduced in both years when rates of ¼ X or greater were applied 30 and 90 DAP while rates of 1/8 X or greater reduced yield when applied 60 DAP.  At the High Plains location, peanut yields were consistently reduced with rates of ½ X or greater applied 30 and 90 DAP and ¼ X or greater applied 60 DAP.  In Oklahoma, peanut yield were consistently reduced with rates of ¼ X or greater applied 30 and 60 DAP and 1/16 X or greater when applied 90 DAP.  Peanut grade was more affected by the 60 and 90 DAP application than the 30 DAP application.

ABSTRACT Field studies were conducted in the Texas High Plains and south Texas to determine peanut response to flumioxazin and paraquat applied preemergence or 7 days after ground cracking (DAC). These herbicides were applied either alone or in combination. Smellmelon control was greater than 90% with all 7 DAC treatments while preemergence (PRE) treatments of flumioxazin plus paraquat controlled 87 to 97% in one of two years. No peanut injury was noted following either herbicide applied preemergence; however, early-season injury (stunting and leaf chlorosis/necrosis) was evident with flumioxazin and paraquat alone or in combination when applied 7 DAC. Early-season injury in south Texas from the 7 DAC applications of flumioxazin and paraquat varied from 9 to 63% with flumioxazin alone, 18 to 65% with paraquat alone, and 33 to 83% with combinations of the two herbicides. Injury in the Texas High Plains was never more than 40% with either herbicide alone or in combination. Mid-season injury in south Texas was at least 13% with any combination that included flumioxazin at 0.11 kg/ha while injury in the Texas High Plains varied from 12 to 25%. Peanut yields were not affected by flumioxazin and paraquat in the High Plains area although yields in south Texas were reduced from the untreated weed-free check with combinations of flumioxazin and paraquat.

The United States is in a bind. On the one hand, we need millions of additional citizens with at least one year of successful post-secondary experience to adapt to the knowledge economy. Both the Gates and Lumina Foundations, and our President, have championed this goal in different ways. On the other hand, we have a post-secondary system that is trapped between rising costs and stagnant effectiveness, seemingly unable to respond effectively to this challenge. This paper analyzes several aspects of this problem, describes changes in the society that create the basis for solutions, and offers several examples from Kaplan University of emerging practice that suggests what good practice might look like in a world where quality-assured mass higher education is the norm.

This article considers the theme of discernment in the tradition of Ignatian spirituality emanating from the Spiritual Exercises of St Ignatius of Loyola (1491-1556), the founder of the Society of Jesus (Jesuits). After a brief introduction which addresses the central problematic of bad influences that manifest themselves as good, the article turns to the life and work of two Jesuits, the 16th C English missionary to India, Thomas Stephens and the 20th C French historian and cultural critic, Michel de Certeau. Both kept up a constant dialogue with local culture in which they sought authenticity in their response to ‘events’, whether a hideous massacre which shaped the pastoral commitment and writing of Stephens in the south of the Portuguese enclave of Goa or the 1968 student-led protests in Paris that so much affected the thinking of de Certeau. Very different in terms of personal background and contemporary experience, they both share in a tradition of discernment as a virtuous response to what both would understand as the ‘wisdom of the Spirit’ revealed in their personal interactions with ‘the other’.
