Interactions of Helicoverpa punctigera (Lepidoptera: Noctuidae) Larvae and Adults With Four Native Host Plants Relative to Field Use Patterns

Abstract Generalist insect herbivores may be recorded from a great variety of host plants. Under natural conditions, however, they are almost invariably associated with a few primary host species on which most of the juveniles develop. We experimentally investigated the interaction of the generalist moth Helicoverpa punctigera Wallengren (Lepidoptera: Noctuidae) with four of its native host plants, two designated primary hosts and two secondary hosts (based on field observations). We tested whether primary host plants support higher survival rates of larvae and whether they are more attractive to ovipositing moths and feeding larvae. We also evaluated whether relative attractiveness of host plants for oviposition matches larval survival rates on them—the preference-performance hypothesis. Moths laid significantly more eggs on two of the four host plant species, one of them a primary host, the other a secondary host. Larvae developed best when reared on the attractive secondary host, developed at intermediate levels on the two primary hosts, and performed worst on the less attractive secondary host. Relative attractiveness of the four host plants to caterpillars differed from that of the moths. Neither adult nor larval attraction to host plants fully supported the preference-performance hypothesis, but oviposition was better correlated with larval survival rates than was larval attraction. Our results suggest the relative frequency at which particular host species are used in the field may depend on factors not yet considered including the long-distance attractants used by moths and the relative distribution of host species.
Climate change impacts on regional maize yields and possible adaptation measures in Argentina

In this work, the impact of future climate (2081-2090) on regional maize yields was assessed through a crop simulation model. The climatic inputs correspond to the regional model MM5/CIMA, considering grids of 50 km * 50 km. Crop model runs were done under typical crop management conditions with and without considering the fertilisation effect of CO2. Without CO2 effects, the impact of future scenarios will be negative in most of the region, attaining mean reductions of 9% and 6% under SRES A2 and B2, respectively. However, yield changes could range between increases of 46% under B2 and decreases of 17% under A2. The inclusion of CO2 effects led to increases in maize yields by 19% under A2 and 11% under B2, although negative impacts could still occur. The adaptation measures related to planting dates and irrigation were assessed as a way to overcome future negative impacts. Without considering CO2, advancing sowings by 15-30 days could be beneficial, increasing yields under B2 and reducing loses under A2. Irrigation requirements could, on average, increase in the central and northern parts of the region and decrease in the southern one. The uncertainties related to future scenarios and the crop responses to CO2 are also discussed.
Polychlorinated biphenyls (PCBs) in the sediments of the River Chenab, Pakistan

Polychlorinated biphenyl (PCBs, sum of 31 congeners) concentrations (ng g−1 dry weight) in sediments collected from the River Chenab during two years of monitoring ranged from 9.33 to 129.45 in winter and from 12.55 to 144.23 in summer. Levels of PCBs in sediments from the feeding tributaries were relatively greater. Sediments from the mainstream sites were dominated by tetra-CBs and penta-CBs, while hepta-CBs and octa-CBs were predominant in industrial and urban sites near tributaries. Factor analysis based on principal component analysis (FA/PCA) and correlation analysis suggested surface run-off from surrounding agricultural soils, direct discharge of industrial and municipal effluents without prior treatment into the aquatic ecosystem, and atmospheric deposition as the main sources of PCB contamination. Risk assessment was carried out by comparing the results with established sediment quality guidelines; PCB concentrations in 35% of sediments exceeded effect range low (ELR) and threshold effect level (TEL) values, however, none of sediments showed PCB concentrations greater than the effect range median (ERM) and probable effect level (PEL) with the exception of site S-20 (144.23 ng g−1, dry weight), which showed values higher than ERL and TEL.
Molecular Dynamics Simulations of a Polyalanine Octapeptide under Ewald Boundary Conditions: Influence of Artificial Periodicity on Peptide Conformation

Ewald and related mesh methods are nowadays routinely used in explicit-solvent simulations of solvated biomolecules, although they impose an artificial periodicity in systems which are inherently nonperiodic. In the present study, we investigate the consequences of this approximation for the conformational equilibrium of a polyalanine octapeptide (with charged termini) in water. We report three explicit-solvent molecular dynamics simulations of this peptide in cubic unit cells of edges L = 2, 3, and 4 nm, using the particle−particle−particle−mesh (P3M) method for handling electrostatic interactions. The initial configuration of the peptide is α-helical. In the largest unit cell (L = 4 nm), the helix unfolds quickly toward configurations with shorter end-to-end distances. By contrast, in the two smaller unit cells (L = 2 and 3 nm), the α-helix remains stable during 2 ns. Backbone fluctuations are somewhat larger in the medium (L = 3 nm) compared to the smallest unit cell. These differences are rationalized.
Modeling the displacement in three-layer electroactive polymers using different counter-ions by a phase transformation approach

The use of three-layer electroactives polymers is becoming more widely known among researchers and engineers because of their potentials to become mechanical actuators. The up-to-date research and development in the Nafion®/Metal composites has given some fundamentals, preparation techniques, and modeling of the phenomena regarding the deformation of the material from different scientific point of view. This gives the opportunity to propose correlations for modeling the phenomena present in these materials by different approaches. A constitutive model for the bending deformation of a Nafion® Ionic Polymer-Metal Composite (IPMC) was formulated based on an approach that represents, analogically, a phase transformation inside the base polymer and combines it with the bending of a beam in order to predict the displacement when the material is subject to an electrical input. The model was solved and evaluated for five different types of counter-ion systems. Experimental data was used to solve the parameters within the model. The results of the solved model gave a good fitting of the experimental data and are shown for different voltage and frequency conditions in all five ionic systems. © 2009 Wiley Periodicals, Inc.

Lookout for learning: Exploring the links between drama and environmental education pedagogies

Abstract Environmental educators remain challenged by how to encourage people to make connections between environmental quality and human development in a way that is socially just and equitable for all living things. This article explores links between performance-based learning and environmental education pedagogy as one way to address this challenge. Sixteen children (8–10 years) from an Auckland primary school worked with a performance artist to present Lookout, an intimate performance by a child for an adult. Its intent was to juxtapose people’s different backgrounds, experiences and ages in a two-way communication of their view of Auckland City through an environmental lens encompassing past, present and future, while surveying the city from a vantage point. Analysis of data from focus groups with the children and interviews with their parents (also participants) showed that the Lookout process led to children developing a deeper understanding of Auckland City’s issues, a stronger sense of connection to their city, an understanding of the future, and feelings of empowerment. However, their parents’ learning was more tenuous. Three key elements to the success of Lookout for learning are identified, and it is proposed that these could be used when developing performance-based environmental education programs.
Investigating language barriers in psychiatric care in Ghana

ABSTRACT Background: In psychiatric care, doctors depend on information from interactions with patients to arrive at the right diagnosis and appropriate therapy (Brisset C, Leanza Y, Rosenberg E, Vissandjée B, Kirmayer LJ, Muckle G, et al. language barriers in mental health care: a survey of primary care practitioners. J Immigr Minor Health. 2014;16(6):1238–46). This is a qualitative descriptive study which seeks to investigate language barriers faced by psychiatrists in their interactions with patients and the effectiveness of the strategies which are employed to deal with the barriers. Methods: Research questions are informed by Convergence (Giles H. Communication Accommodation Theory. In: Baxter LA, Braithewaite DO, editors. Engaging theories in interpersonal communication: multiple perspectives. Thousand Oaks ( CA): Sage Publications; 2008. p. 161–73). Using semi-structured interviews, psychiatric doctors from the three state-owned psychiatric hospitals in Ghana report their experiences with convergence strategies they use, and offer suggestions that could inform future studies and policy formulation with regard to psychiatric care in Ghana. A qualitative conventional content analysis was applied whereby coding categories were derived straight from the text data. Results: The literature suggests that the study is novel with reference to Ghana. Similar studies (Lee E.

New York (NY): The Guilford Press; 1997; Swartz L, Drennan G. Beyond Words: notes on the ‘irrelevance’ of language to mental health services in South Africa. Transcult Psychiatry. 2000;37(2):185–201; Jarvis GE, Ahmed R, Ryder A, Kirmayer LJ. Assessing language barriers to mental health services in a multiethnic population: preliminary findings. Presentation at Health care Access for Linguistic Minorities: Breaking the Barriers. Montreal, Quebec, Canada; 2014) corroborate this paper’s findings that language barriers have the potential of causing misdiagnoses if psychiatrists do not employ effective communication strategies. Conclusions: The paper recommends areas for further research and improvement measures which carry policy implications.
Dog Urine Has Acute Impacts on Soil Chemistry in Urban Greenspaces

Urban residents and their pets utilize urban greenspaces daily. As urban dog ownership rates increase globally, urban greenspaces are under mounting pressure even as the benefits and services they provide become more important. The urine of dogs is high in nitrogen (N) and may represent a significant portion of the annual urban N load. We examined the spatial distribution and impact of N deposition from dog urine on soils in three urban greenspace typologies in Finland: Parks, Tree Alleys, and Remnant Forests. We analyzed soil from around trees, lampposts and lawn areas near walking paths, and compared these to soils from lawn areas 8 m away from pathways. Soil nitrate, ammonium, total N concentrations, and electrical conductivity were significantly higher and soil pH significantly lower near path-side trees and poles relative to the 8 m lawn plots. Also, stable isotope analysis indicates that the primary source of path-side N are distinct from those of the 8 m lawn plots, supporting our hypothesis that dogs are a significant source of N in urban greenspaces, but that this deposition occurs in a restricted zone associated with walking paths. Additionally, we found that Remnant Forests were the least impacted of the three typologies analyzed. We recommend that landscape planners acknowledge this impact, and design parks to reduce or isolate this source of N from the wider environment.
The 1974 West Flank Eruption of Mount Etna: A Data-Driven Model for a Low Elevation Effusive Event

Low elevation flank eruptions represent highly hazardous events due to their location near, or in, communities. Their potentially high effusion rates can feed fast moving lava flows that enter populated areas with little time for warning or evacuation, as was the case at Nyiragongo in 1977. The January–March 1974 eruption on the western flank of Mount Etna, Italy, was a low elevation effusive event, but with low effusion rates. It consisted of two eruptive phases, separated by 23 days of quiescence, and produced two lava flow fields. We describe the different properties of the two lava flow fields through structural and morphological analyses using UAV-based photogrammetry, plus textural and rheological analyses of samples. Phase I produced lower density (∼2,210 kg m−3) and crystallinity (∼37%) lavas at higher eruption temperatures (∼1,080°C), forming thinner (2–3 m) flow units with less-well-developed channels than Phase II. Although Phase II involved an identical source magma, it had higher densities (∼2,425 kg m−3) and crystallinities (∼40%), and lower eruption temperatures (∼1,030°C), forming thicker (5 m) flow units with well-formed channels. These contrasting properties were associated with distinct rheologies, Phase I lavas having lower viscosities (∼103 Pa s) than Phase II (∼105 Pa s). Effusion rates were higher during Phase I (≥5 m3/s), but the episodic, short-lived nature of each lava flow emplacement event meant that flows were volume-limited and short (≤1.5 km). Phase II effusion rates were lower (≤4 m3/s), but sustained effusion led to flow units that could still extend 1.3 km, although volume limits resulted from levee failure and flow avulsion to form new channels high in the lava flow system. We present a petrologically-based model whereby a similar magma fed both phases, but slower ascent during Phase II may have led to greater degrees of degassing resulting in higher cooling-induced densities and crystallinities, as well as lower temperatures. We thus define a low effusion rate end-member scenario for low elevation effusive events, revealing that such events are not necessarily of high effusion rate and velocity, as in the catastrophic event scenarios of Etna 1669 or Kilauea 2018.
Evidence for [Coronal] Underspecification in Typical and Atypical Phonological Development

The Featurally Underspecified Lexicon (FUL) theory predicts that [coronal] is the language universal default place of articulation for phonemes. This assumption has been consistently supported with adult behavioral and event-related potential (ERP) data; however, this underspecification claim has not been tested in developmental populations. The purpose of this study was to determine whether children demonstrate [coronal] underspecification patterns similar to those of adults. Two English consonants differing in place of articulation, [labial] /b/ and [coronal] /d/, were presented to 24 children (ages 4–6 years) characterized by either a typically developing phonological system (TD) or a phonological disorder (PD). Two syllables, /bɑ/ and /dɑ/, were presented in an ERP oddball paradigm where both syllables served as the standard and deviant stimulus in opposite stimulus sets. Underspecification was examined with three analyses: traditional mean amplitude measurements, cluster-based permutation tests, and single-trial general linear model (GLM) analyses of single-subject data. Contrary to previous adult findings, children with PD demonstrated a large positive mismatch response (PMR) to /bɑ/ while the children with TD exhibited a negative mismatch response (MMN); significant group differences were not observed in the /dɑ/ responses. Moreover, the /bɑ/ deviant ERP response was significantly larger in the TD children than in the children with PD. At the single-subject level, more children demonstrated mismatch responses to /dɑ/ than to /bɑ/, though some children had a /bɑ/ mismatch response and no /dɑ/ mismatch response. While both groups of children demonstrated similar responses to the underspecified /dɑ/, their neural responses to the more specified /bɑ/ varied. These findings are interpreted within a proposed developmental model of phonological underspecification, wherein children with PD are functioning at a developmentally less mature stage of phonological acquisition than their same-aged TD peers. Thus, phonological underspecification is a phenomenon that likely develops over time with experience and exposure to language.
Antibiotic Treatment for Chronic Rhinosinusitis: Prescription Patterns and Associations With Patient Outcome and the Sinus Microbiota

Background Chronic rhinosinusitis (CRS) is a common and debilitating inflammatory condition of the sinuses, afflicting 5% of the general population. Although antibiotics are frequently prescribed for the medical management of CRS, there is surprisingly little evidence to support their efficacy. In this study, we aimed to establish associations between medication usage, the sinus microbiota and patients’ clinical outcomes. Methods Antibiotic prescription patterns for the year before sample collection of 156 CRS patients, 45 disease control patients (mostly requiring septoplasty and inferior turbinate reduction) and 35 healthy control subjects were examined and analyzed together with previously published bacterial 16S rRNA gene amplicon data from our group. Results The highest antibiotic usage was observed among the two CRS patient categories. Despite heavy antibiotic usage, CRS patients’ clinical outcomes as indicated by patient questionnaires and radiologic scores were similar to those patients that did not receive any antibiotics. The sinus microbiota was dominated by members of the bacterial genera Corynebacterium and Staphylococcus in all three cohorts. Bacterial community dispersion as measured by principal coordinate analysis was significantly higher in CRS patients compared to healthy control subjects, but not disease control patients. Pairwise comparisons within cohorts revealed differences in the relative 16S rRNA gene sequence abundances of the genera Staphylococcus and Lawsonella between antibiotic users and non-users. However, overall antibiotic effects were minimal and unpredictable. Conclusion The unpredictable effects of antibiotic treatment on the sinus microbiota found in this study, together with the lack of differences in patients’ symptom scores between cohorts, do not support preoperative antibiotic treatment for CRS patients.
Industrial-Scale Production and Applications of Bacterial Cellulose

Bacterial cellulose (BC) is a natural biomaterial synthesized by bacteria. It possesses a unique structure of cellulose nanofiber-weaved three-dimensional reticulated network that endows it excellent mechanical properties, high water holding capability and outstanding suspension stability. It is also characterized with high purity, high degree of crystallinity, great biocompatibility and biodegradability. Due to these advantages, BC has gained great attentions in both academic and industrial areas. This critical review summarizes the up-to-date development of BC production and application from an industrial perspective. Firstly, a fundamental knowledge of BC's biosynthesis, structure and properties is described, and then recent developments in the industrial fermentation of BC are introduced. Subsequently, the latest commercial applications of BC in the areas of food, personal care, household chemicals, biomedicine, textile, composite resin are summarized. Finally, a brief discussion of future development of BC industry is presented at the end.
Menstrual Cycle Variations in Gray Matter Volume, White Matter Volume and Functional Connectivity: Critical Impact on Parietal Lobe

The role of gonadal hormones in neural plasticity remains unclear. This study aimed to examine the effects of naturally fluctuating hormone levels over the menstrual cycle in healthy females. Gray matter, functional connectivity (FC) and white matter changes over the cycle were assessed by using functional magnetic resonance imaging (fMRI), resting state fMRI, and structural MRIs, respectively, and associated with serum gonadal hormone levels. Moreover, electrocutaneous sensitivity was evaluated in 14 women in four phases of their menstrual cycle (menstrual, follicular, ovulatory, and luteal). Electrocutaneous sensitivity was greater during follicular compared to menstrual phase. Additionally, pain unpleasantness was lower in follicular phase than other phases while pain intensity ratings did not change over the cycle. Significant variations in cycle phase effects on gray matter volume were found in the left inferior parietal lobule (IPL) using voxel-based morphometry. Subsequent Freesurfer analysis revealed greater thickness of left IPL during the menstrual phase when compared to other phases. Also, white matter volume fluctuated across phases in left IPL. Blood estradiol was positively correlated with white matter volume both in left parietal cortex and whole cortex. Seed-driven FC between left IPL and right secondary visual cortex was enhanced during ovulatory phase. A seed placed in right IPL revealed enhanced FC between left and right IPL during the ovulatory phase. Additionally, we found that somatosensory cortical gray matter was thinner during follicular compared to menstrual phase. We discuss these results in the context of likely evolutionary pressures selecting for enhanced perceptual sensitivity across modalities specifically during ovulation.
Co-emergence Reinforcement and Its Relevance to Interoceptive Desensitization in Mindfulness and Therapies Aiming at Transdiagnostic Efficacy

Interoception, the ability to feel the body’s internal sensations, is an essential aspect of emotional experience. There is mounting evidence that interoception is impaired in common mental health disorders and that poor interoceptive awareness is a major contributor to emotional reactivity, calling for clinical interventions to address this deficit. The manuscript presents a comprehensive theoretical review, drawing on multidisciplinary findings to propose a metatheory of reinforcement mechanisms applicable across a wide range of disorders. We present a reconsideration of operant conditioning through the co-emergence model of reinforcement, which is a neurophenomenological account of the interaction between cognition and interoception, and its consequences on behavior. The model suggests that during memory processing, the retrieval of autobiographical memory (including maladaptive cognition) is dependent upon its co-emerging interoceptive cues occurring at the encoding, consolidation and reconsolidation stages. Accordingly, “interoceptive reinforcement” during emotional distress is a common factor to all emotional disorders and a major cause for relapse. We propose that interoceptive desensitization has transdiagnostic benefits, readily achievable through the cultivation of equanimity during mindfulness training and can be integrated in cognitive and behavioral interventions to permit a transdiagnostic applicability. We summarize the contributions of this approach into 10 specific and testable propositions.
