The 2022 Mid-Term Elections in Illinois: Unfinished Business or The Wave of The Future?

Part I of this paper provides a description of the Democratic and Republican Primaries in Illinois for the mid-term elections of 2022. Part II then turns to the general election campaigns focusing on the governor’s race between incumbent Democrat J. B. Pritzker and his Republican challenger, State Senator Darren Bailey. The race for the U. S. Senate between the incumbent, Tammy Duckworth, and Kathy Salvi, and the state’s Constitutional Offices are also analyzed. The unit of analysis utilized is the county-level aggregate data voting returns. Part III deals with the aftermath of the November election with a focus on the SAFE-T Act and the assault weapons ban, at the end of November since the veto session agenda was an extension of the preceding election. The results show how the state races were inextricably set into the context of the national tides that had produced a deeply polarized America and how this played out in the traditionally blue state of Illinois. These prominent issues continued to rile Illinois and national politics, and helped define the major differences between the two parties. The debate over them continued immediately after the election and started to set the stage for the second Pritzker administration and the beginning of the 2024 national election. In addition, the vote on the new amendment to the Illinois constitution providing protection for the rights of organized labor is analyzed. Extensive economic data are presented, differentiating the counties which voted for the amendment and those which voted against it. Those counties are also compared to the Pritzker vs. Bailey counties

Monitoring and assessing land degradation: new approaches

This chapter examines land degradation in southern Africa. The focus is on the major issue of erosion by water at scales ranging from a few square metres to assessments that aim to cover the whole region. Approaches to measure and reconstruct both current and historical erosion rates are considered, focusing on the period since the arrival of Europeans who brought many of their farming and management practices with them. In most parts of the country, the impact of humans on the landscape has been clear for the last 200 years. This is referred to as ’accelerated erosion’, i.e., erosion at rates that are above the natural geological norm for the current climatic conditions. The chapter considers a range of techniques including direct measurement, remote sensing, fingerprinting and modelling as approaches to the monitoring and assess land degradation

HIV-1 Nef: at the crossroads

The development of anti-virals has blunted the AIDS epidemic in the Western world but globally the epidemic has not been curtailed. Standard vaccines have not worked, and attenuated vaccines are not being developed because of safety concerns. Interest in attenuated vaccines has centered on isolated cases of patients infected with HIV-1 containing a deleted nef gene. Nef is a multifunctional accessory protein that is necessary for full HIV-1 virulence. Unfortunately, some patients infected with the nef-deleted virus eventually lose their CD4+ T cells to levels indicating progression to AIDS

Development of food photographs for use with children aged 18 months to 16 years:comparison against weighed food diaries – The Young Person’s Food Atlas (UK)

Traditional dietary assessment methods, used in the UK, such as weighed food diaries impose a large participant burden, often resulting in difficulty recruiting representative samples and underreporting of energy intakes. One approach to reducing the burden placed on the participant is to use portion size assessment tools to obtain an estimate of the amount of food consumed, removing the need to weigh all foods. An age range specific food atlas was developed for use in assessing children’s dietary intakes. The foods selected and portion sizes depicted were derived from intakes recorded during the UK National Diet and Nutrition Surveys of children aged 1.5 to 16 years. Estimates of food portion sizes using the food atlas were compared against 4-day weighed intakes along with in-school / nursery observations, by the research team. Interviews were conducted with parents the day after completion of the diary, and for children aged 4 to 16 years, also with the child. Mean estimates of portion size consumed were within 7% of the weight of food recorded in the weighed food diary. The limits of agreement were wide indicating high variability of estimates at the individual level but the precision increased with increasing age. For children 11 years and over, agreement with weighed food diaries, was as good as that of their parents in terms of total weight of food consumed and of intake of energy and key nutrients. The age appropriate food photographs offer an alternative to weighed intakes for dietary assessment with children

Amplified fragment length polymorphism used for inter- and intraspecific differentiation of screwworms (Diptera: Calliphoridae)

Morphologically, early immature stages of the economically important pest called screwworms, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), and non-pest secondary screwworms, Cochliomyia macellaria (Fabricius) (Diptera: Calliphoridae), are nearly indistinguishable. Correct identification is crucial to the ongoing eradication and exclusion program protecting the United States, Mexico and Central America from reinvasion of screwworms persistent in South America and the Caribbean. Amplified fragment length polymorphism (AFLP) polymerase chain reaction was used to differentiate populations of C. hominivorax and to discriminate them from C. macellaria. Ten primer pairs screened for interspecific discrimination of C. hominivorax from C. macellaria showed 52 discrete bands, allowing the two species to be readily distinguished; divergent branches on resulting dendrograms showed 100% bootstrap support. C. macellaria populations grouped at the 92% level; C. hominivorax populations grouped at the 68% level. Of the 52 bands, seven were monomorphic for both species, 22 were specific to C. macellaria, ten were present only in C. hominivorax and the remaining 13 bands differentiated C. hominivorax populations. Separate studies using ten strains of C. hominivorax showed a higher level of genetic similarity within than between populations. Analyses using 72 bands (19 monomorphic bands, 53 bands grouped all ten strains at the 58% similarity level) resolved seven mutant strains from Mexico (85% similarity level); all ten strains were resolved at the 72% similarity level. Diagnostic bands were identified for species and strain identification. We conclude that AFLP can be a valuable tool for studies of interspecific and intraspecific genetic variation in screwworm populations

Professional Development in CTE Data Driven Methods: Development of a Research-Based Intervention

An initial survey conducted by the authors in 2009 determined the amount and type of preparation career technical educators (CTE) had regarding the use of assessment data for program and instructional improvement; this survey was the basis for development of an intervention for teachers on interpretation of assessment data for improvement of classroom instruction. The intervention, titled Career and Technical Educators Using a Data Driven Improvement Model or CTEDDI, was developed and successfully piloted in five states during spring semester 2010; the results of the pilot study have been used to revise the materials and process to produce a professional development program to help CTE educators improve their data skills and instruction

Molecular phylogeny of Diabrotica beetles (Coleoptera: Chrysomelidae) inferred from analysis of combined mitochondrial and nuclear DNA sequences

The phylogenetic relationships of thirteen Diabrotica (representing virgifera and fucata species groups) and two outgroup Acalymma beetle species (Coleoptera: Chrysomelidae) were inferred from the phylogenetic analysis of a combined data set of 1323 bp of mitochondrial DNA (mtDNA) cytochrome oxidase subunit 1 (COI) and the entire second internal transcribed spacer region (ITS-2) of nuclear ribosomal DNA of 362 characters. Species investigated were D. adelpha, D. balteata, D. barberi, D. cristata, D. lemniscata, D. longicornis, D. porracea, D. speciosa, D. undecimpunctata howardi, D. u. undecimpunctata, D. virgifera virgifera, D. v. zeae, D. viridula, and outgroup A. blandulum and A. vittatum. Maximum parsimony (MP), minimum evolution (ME), and maximum likelihood (ML) analyses of combined COI and ITS-2 sequences clearly place species into their traditional morphological species groups with MP and ME analyses resulting in identical topologies. Results generally confer with a prior work based on allozyme data, but within the virgifera species group, D. barberi and D. longicornis strongly resolve as sister taxa as well as monophyletic with the neotropical species, D. viridula, D. cristata and D. lemniscata also resolve as sister taxa. Both relationships are not in congruence with the prior allozyme-based hypothesis. Within the fucata species group, D. speciosa and D. balteata resolve as sister taxa. Results also strongly supported the D. virgifera and D. undecimpunctata subspecies complexes. Our proposed phylogeny provides some insight into current hypotheses regarding distribution status and evolution of various life history traits for Diabrotica

APOBEC3G and APOBEC3F Act in Concert To Extinguish HIV-1 Replication

ABSTRACT The multifunctional HIV-1 accessory protein Vif counters the antiviral activities of APOBEC3G (A3G) and APOBEC3F (A3F), and some Vifs counter stable alleles of APOBEC3H (A3H). Studies in humanized mice have shown that HIV-1 lacking Vif expression is not viable. Here, we look at the relative contributions of the three APOBEC3s to viral extinction. Inoculation of bone marrow/liver/thymus (BLT) mice with CCR5-tropic HIV-1 JRCSF (JRCSF) expressing a vif gene inactive for A3G but not A3F degradation activity (JRCSFvifH42/43D) displayed either no or delayed replication. JRCSF expressing a vif gene mutated to inactivate A3F degradation but not A3G degradation (JRCSFvifW79S) always replicated to high viral loads with variable delays. JRCSF with vif mutated to lack both A3G and A3F degradation activities (JRCSFvifH42/43DW79S) failed to replicate, mimicking JRCSF without Vif expression (JRCSFΔvif). JRCSF and JRCSFvifH42/43D, but not JRCSFvifW79S or JRCSFvifH42/43DW79S, degraded APOBEC3D. With one exception, JRCSFs expressing mutant Vifs that replicated acquired enforced vif mutations. These mutations partially restored A3G or A3F degradation activity and fully replaced JRCSFvifH42/43D or JRCSFvifW79S by 10 weeks. Surprisingly, induced mutations temporally lagged behind high levels of virus in blood. In the exceptional case, JRCSFvifH42/43D replicated after a prolonged delay with no mutations in vif but instead a V27I mutation in the RNase H coding sequence. JRCSFvifH42/43D infections exhibited massive GG/AG mutations in pol viral DNA, but in viral RNA, there were no fixed mutations in the Gag or reverse transcriptase coding sequence. A3H did not contribute to viral extinction but, in combination with A3F, could delay JRCSF replication. A3H was also found to hypermutate viral DNA. IMPORTANCE Vif degradation of A3G and A3F enhances viral fitness, as virus with even a partially restored capacity for degradation outgrows JRCSFvifH42/43D and JRCSFvifW79S. Unexpectedly, fixation of mutations that replaced H42/43D or W79S in viral RNA lagged behind the appearance of high viral loads. In one exceptional JRCSFvifH42/43D infection, vif was unchanged but replication proceeded after a long delay. These results suggest that Vif binds and inhibits the non-cytosine deaminase activities of intact A3G and intact A3F, allowing JRCSFvifH42/43D and JRCSFvifW79S to replicate with reduced fitness. Subsequently, enhanced Vif function is acquired by enforced mutations. In infected cells, JRCSFΔvif and JRCSFvifH42/43DW79S are exposed to active A3F and A3G and fail to replicate. JRCSFvifH42/43D Vif degrades A3F and, in some cases, overcomes A3G mutagenic activity to replicate. Vif may have evolved to inhibit A3F and A3G by stoichiometric binding and subsequently acquired the ability to target these proteins to proteasomes

Differentiation of Three Phenotypically Similar \u3ci\u3eBlattella\u3c/i\u3e spp.: Analysis with Polymerase Chain Reaction-Restriction Fragment Length Polymorphism of Mitochondrial DNA

Differentiation of Blattella asahinai Mizukubo, Blattella vaga Hebard, and Blattella germanica (L.) was investigated using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). DNA fragments corresponding to mitochondrial CO1,CO1/TL2(small and large fragments), and ITS2 regions were amplified using PCR. The universal primers used for amplifying mitochondrial CO1 and CO1/TL2 (small and large fragments) were CO1-J-1718/CO1- N-2191, CO1-J-2441/TL2-N-3014, and CO1-J-1751/TL2-N-3014. Amplification was observed with all primer combinations, but diagnostic patterns were found only with AluI digested amplicons of CO1 and CO1/TL2 (large fragments) regions. Both inter/intraspecific polymorphism was observed for the 517 bp CO1 region between German (A, B) and Asian (A, B, C) cockroach populations. Polymorphic form B of the Asian cockroach (374 and 179 bp fragments) was nearly identical to the field cockroach (370 and 178 bp fragments). The CO1 amplicon (517 bp) differentiated German and field cockroaches but not Asian and field cockroaches. The CO1/TL2 amplicons (1275 bp) digested with AluI clearly differentiated all three species. The Asian cockroach had a distinct 540 bp fragment, whereas the field cockroach had a 403 bp fragment and the German cockroach lacked both fragments. Intraspecific polymorphs for CO1/TL2 amplicons (1275 bp) were observed with the German cockroach only. Portions of the CO1 and TL2 genes were sequenced, revealing 76% identity among German, Asian, and field cockroaches. Sequence data also revealed that German and Asian cockroaches were more closely related to each other than to the field cockroach
