Evaluation of the use of psychometric scales to determine attitudes towards predators in human-wildlife interaction research

Studies evaluating human–wildlife interactions (HWIs) in a conservation context often include psychometric scales to measure attitudes and tolerance toward wildlife. However, data quality is at risk when such scales are used without appropriate validation or reliability testing, potentially leading to erroneous interpretation or application of findings. We used 2 online databases (ProQuest Psych Info and Web of Science) to identify published HWI studies that included attitude and tolerance. We analyzed these studies to determine the methods used to measure attitudes or tolerance toward predators and other wildlife; determine the proportion of these methods applying psychometric scales; and evaluate the rigor with which the scales were used by examining whether the psychometric properties of validity and reliability were reported. From 2007 to 2017, 114 published studies were identified. Ninety-four (82%) used questionnaires and many of these (53 [56%]) utilized a psychometric scale. Most scales (39 [74%]) had at least 1 test of reliability reported, but reliance on a single test was notable, contrary to recommended practice. Fewer studies (35 [66%]) reported a test of validity, but this was primarily restricted to structural validity rather than more comprehensive testing. Encouragingly, HWI investigators increasingly utilized the necessary psychometric tools for designing and analyzing questionnaire data, but failure to assess the validity or reliability of psychometric scales used in over one-third of published HWI attitude research warrants attention. We advocate incorporation of more robust application of psychometric scales to advance understanding of stakeholder attitudes as they relate to HWI.
Characterizing Vascular and Neuronal Defects in Williams-Beuren Syndrome and 7q11.23 Duplication Syndrome Using Induced Pluripotent Stem Cells

Williams-Beuren syndrome (WBS) and 7q11.23 duplication syndrome (Dup7) are caused by the deletion and duplication, respectively, of 26-28 genes on chromosome 7 in humans, affecting the cardiovascular and nervous systems. To model WBS and Dup7, we generated induced pluripotent stem cells (iPSCs) from multiple WBS, Dup7, and healthy control individuals. In iPSC-derived smooth muscle cells (SMCs), I found an increase in proliferation and reduction in differentiation among WBS SMCs, while also finding elevated proportions of SMC marker in Dup7 precursors, indicating premature differentiation. Assessing neuronal morphology in iPSC-derived neurons, when co-cultured and compared with similarly derived control neurons, axon and dendrite lengths were increased in Dup7 neurons and soma size was increased in both WBS and Dup7 neurons. Further characterization of such phenotypes will provide insight into the pathology underlying the cardiovascular and neurobehavioural symptoms of WBS and Dup7 and inform how they can be addressed at a clinical level.
Control strategies and gene expression dynamics of the plant pathogen Ralstonia solanacearum = Estratègies de control i dinàmica d'expressió gènica en el fitopatogen Ralstonia solanacearum

Ralstonia solanacearum is the causative agent of bacterial wilt of potato. Ralstonia solanacearum strain UY031 belongs to the American phylotype IIB, sequevar 1, also classified as race 3 biovar 2. Here we report the completely sequenced genome of this strain, the first complete genome for phylotype IIB, sequevar 1, and the fourth for the R. solanacearum species complex. In addition to standard genome annotation, we have carried out a curated annotation of type III effector genes, an important pathogenicity-related class of genes for this organism. We identified 60 effector genes, and observed that this effector repertoire is distinct when compared to those from other phylotype IIB strains. Eleven of the effectors appear to be nonfunctional due to disruptive mutations. We also report a methylome analysis of this genome, the first for a R. solanacearum strain. This analysis helped us note the presence of a toxin gene within a region of probable phage origin, raising the hypothesis that this gene may play a role in this strain’s virulence.
Deep residual learning for neuroimaging: An application to predict progression to Alzheimer’s disease

This work investigates the suitability of deep residual neural networks (ResNets) for studying neuroimaging data in the specific application of predicting progression from mild cognitive impairment (MCI) to Alzheimer’s disease (AD). We focus on predicting the subset of MCI individuals that would progress to AD within three years (progressive MCI) and the subset of MCI individuals that do not progress to AD within this period (stable MCI). This prediction was conducted first as a standard binary classification task by training a ResNet architecture using MCI individuals only, followed by a modified domain transfer learning version that additionally trained on the AD and cognitively normal (CN) individuals. For this modified inter-MCI classification task, the ResNet architecture achieved better than state-of-the-art performance in predicting progression to AD using structural MRI data alone (> 7% than the second best performing method), within 1% of the state-of-the-art performance considering learning using multiple structural modalities as well, and a significant performance improvement over the classical support vector machine learning framework (p = 2.5762 x 10−8). The learnt surrogate (i.e. cross-validation-fold-specific) models and the final predictive model (trained on all data) in this modified classification task showed highly similar peak activations, significant correspondence of which in the medial temporal lobe and other areas could be established with previous reports in AD literature, thus further validating our findings. Our results highlight the possibility of early identification of modifiable risk factors for understanding progression to AD using similar advanced deep learning architectures.
Fighting death with health inequality: The role of mortality cognition and shifting racial demographics in policy attitudes

White Americans are predicted to soon comprise less than half of the U.S. population. Such demographic changes can affect political attitudes by threatening group status. The present studies built from this literature to examine a process in which information about such demographic shifts can also affect health policy attitudes, in part by increasing death-related thoughts, and that health inequalities may in turn buffer such cognitions. Three experiments (N = 1,651) adopted a causal chain approach to test these ideas. In Study 1, exposure to demographic changes decreased support for equitable health policies. In Study 2, the demographic manipulation increased death-thought accessibility, unless paired with information about worsening health inequalities. In Study 3, contemplation of mortality lessened both support for equitable health policies and resources allocated to health equity. Health inequalities may mitigate existential concerns raised by shifting racial demographics.
On the rediscovery of Volvox perglobator (Volvocales, Chlorophyceae) and the evolution of outcrossing from self-fertilization

Hypothesis: Genetic recombination underlies the frequent origins of self-fertilization and rare reversions to outcrossing. Organisms: Volvox perglobator, Gonium pectorale, volvocine green algae. Methods: We report the rediscovery of a volvocine alga, obligate outcrossing V. perglobator, including morphological characteristics and molecular phylogeny. We use ancestral-state reconstruction and phylogenetic simulation to demonstrate multiple transitions between selffertilization and outcrossing. We sequence sex-determining genes in multiple volvocine algae. Results: We find significant support for numerous origins of self-fertilization and multiple reversions to outcrossing. Volvox perglobator is one of these reversions to outcrossing. Combination of ancestrally sex-restricted and sex-determining genes into the same genotype correlates with the evolution of self-fertilization. Re-segregation of these same sex-determining loci into separate sexes correlates with the evolution of outcrossing. These results suggest that recombination underlies the evolutionary transitions between self-fertilization and outcrossing in the volvocine algae.
Community analysis of coral mucus-associated bacteria and impact of temperature and CO

The coral holobiont is a complex assemblage of the coral animal and microbial organism. Coral mucus harbours distinct microbial communities and bacteria living in the coral mucus play a major role in the survival of corals. While several studies have assessed their importance in protecting their coral hosts from disease, very little is known about the response of these bacteria to climate change. One of the major consequences of climate changes are enhanced ocean temperatures which lead to coral bleaching. Another major cause of coral bleaching is the increased amount of anthropogenic carbon dioxide (CO2) which leads to a phenomenon called ocean acidification. In both cases, very little its known about how bacteria living in the coral mucus react to the changing conditions. In a laboratory-based experiment, we assessed the impact of temperature and carbon dioxide elevation on mucus-associated bacteria in Trachyphyllia geoffroyi, Euphyllia ancora and Corallimorphs sp. Fragments of the selected corals were placed into tanks and exposed to enhanced concentrations of CO2 and temperature in a series of experiments. Coral mucus samples were collected on a weekly basis and CO2 concentrations monitored using a Fourier-Transform Infrared (FTIR) trace gas analyzer. Potential changes in the coral mucus-associated bacteria communities were monitored by (a) culture based and (b) molecular approaches. Mucus samples were cultured weekly and bacterial isolates identified using Sanger sequencing. Furthermore, fingerprinting methods such as Denaturing Gel Gradient Electrophoresis (DGGE) and Ribosomal Intergenic Spacer analysis (RISA) were applied to monitor changes in the microbial communities. Enzymatic properties (amylase, caseinase, gelatinase and phospholipase) of the coral mucusassociated bacteria were also assessed to identify potential pathogenic bacteria. Significant shifts were detected in all three corals. For Trachyphyllia geoffroyi, Euphyllia ancora and Corallimorphs sp. , When the temperature and carbon dioxide were maintained around 25°C to 28°C and 500 ppm, Vibrio sp. , Bacillus sp. and Pseudomonas sp. were found but as temperature increases up to 29°C, Bacillus sp. started to dominate. However, when both temperature and carbon dioxide were rised up to stressful conditions for the corals, Vibrio sp. dominated the corals mucus layers. Lastly, the isolation of bacteriophage that has the ability to cause a plaque in the Bacteriophage Plaque Assay when tested against selected potential pathogens was also identified. The species identified are phylogenetically 96% similar to Enterobacteriophage reference strain, which are potential bacteriophages for the inhibition of marine pathogens. There were shifts in Trachyphyllia geoffroyi, Euphyllia ancora and Corallimorphs sp. mucusassociated bacteria community when temperature and carbon dioxide content of the corals surrounding changes.
Fully Biobased Superpolymers of 2,5-Furandicarboxylic Acid with Different Functional Properties: From Rigid to Flexible, High Performant Packaging Materials

In the present paper, four fully biobased homopolyesters of 2,5-furandicarboxylic acid (2,5-FDCA) with a high molecular weight have been successfully synthesized by two-stage melt polycondensation, starting from the dimethyl ester of 2,5-FDCA and glycols of different lengths (the number of methylene groups ranged from 3 to 6). The synthesized polyesters have been first subjected to an accurate molecular characterization by NMR and gel-permeation chromatography. Afterward, the samples have been successfully processed into free-standing thin films (thickness comprised between 150 to 180 μm) by compression molding. Such films have been characterized from the structural (by wide-angle X-ray scattering and small-angle X-ray scattering), thermal (by differential scanning calorimetry and thermogravimetric analysis), mechanical (by tensile test), and gas barrier (by permeability measurements) point of view. The glycol subunit length was revealed to be the key parameter in determining the kind and fraction of ordered phases developed by the sample during compression molding and subsequent cooling. After storage at room temperature for one month, only the homopolymers containing the glycol subunit with an even number of −CH2– groups (poly(butylene 2,5-furanoate) (PBF) and poly(hexamethylene 2,5-furanoate) (PHF)) were able to develop a three-dimensional ordered crystalline phase in addition to the amorphous one, the other two appearing completely amorphous (poly(propylene 2,5-furanoate (PPF) and poly(pentamethylene 2,5-furanoate) (PPeF)). From X-ray scattering experiments using synchrotron radiation, it was possible to evidence a third phase characterized by a lower degree of order (one- or two-dimensional), called a mesophase, in all the samples under study, its fraction being strictly related to the glycol subunit length: PPeF was found to be the sample with the highest fraction of mesophase followed by PHF. Such a mesophase, together with the amorphous and the eventually present crystalline phase, significantly impacted the mechanical and barrier properties, these last being particularly outstanding for PPeF, the polyester with the highest fraction of mesophase among those synthesized in the present work.
A Novel NLOS Target Localization Method with a Synthetic Bistatic MMW Radar

In this paper, we focus on exploiting multipath returns to locate the Non-Line-of Sight (NLOS) target behind corner with a synthetic bistatic MilliMeter Wave (MMW) radar. The designed synthetic bistatic MMW radar uses Lidar to obtain the two-Dimensional (2-D) scenario layout, and forms a virtual bistatic through the movement of MMW radar. With the designed system, a novel location method is proposed combining the Times of Arrivel (TOAs). According to real data experiments, the proposed approach has a better positioning accuracy than the method based on Direction of Arrival (DOA) estimation does.
Increase in reproductive ability of high-producing cows, and qualitative parameters of their offspring, under conditions of intensive milk production

Objective: To study the methods of increasing the reproductive qualities and indices of viability in the offspring of Holstein cows under conditions of intensive milk production. Methods: Studies were conducted on 3 groups of Holstein cows with 30 heads in each group. Animals of the experimental groups had a different length physiological period. The study focused on experimental groups of animals: the reproductive indicators, the viability of newborn calves, and their growth rate. All the digital materials of the experimental data were processed by the method of variation statistics for the significance of the difference of the compared parameters using the Student’s criterion, adopted in biology and zootechnics. Results: Studies found that reduction of the duration of the service period, along with a simultaneous increase in the inter-lactation period to 80-90 days, increased the reproductive capacity of the cows, and enhances the viability of the offspring compared with their peers. Conclusions: The study revealed the optimal duration of the physiological periods in high- producing cows under conditions of intensive milk production technology.
Mohamedia, a new genus of Lejeuneaceae (Marchantiophyta) from Oceania and tropical Asia

Abstract. Lejeuneaceae is the largest family of liverworts with an estimated 1800 species in about 73 genera. The systematic position of a number of taxa in the family remains ambiguous owing to the lack of molecular data and morphological observations especially on oil bodies and ocelli in fresh samples. Drepanolejeunea brunnea Mizut. and Lepidolejeunea borneensis (Steph.) R.M. Schust. are two examples of these taxa. Here we investigate the phylogenetic relationships of these two species by using the nuclear ribosomal ITS region and two chloroplast regions (rbcL, trnL–trnF). The molecular data show that Drepanolejeunea brunnea and Lepidolejeunea borneensis form a well-supported clade unrelated to Drepanolejeunea (Spruce) Steph. and Lepidolejeunea R.M. Schust. On the basis of the combined molecular-phylogenetic and morphological data, a new genus in the subtribe Lepidolejeuneinae, Mohamedia R.L. Zhu et L.Shu, is described to accommodate Drepanolejeunea brunnea and Lepidolejeunea borneensis. Mohamedia is closely related to Otolejeunea Tixier endemic to Madagascar, but differs in the thinner stem with only 3(–4) rows of medullary cells, perianths with 4–5 crenulate to weakly dentate keels and without auricles, and lack of an unbroken row of ocelli in leaf lobes. Two new subgenera, Mohamedia subg. Mohamedia and Mohamedia subg. Piippolejeunea R.L. Zhu et L.Shu, are described and the new combinations (Mohamedia brunnea (Mizut.) R.L. Zhu et L.Shu and M. borneensis (Steph.) R.L. Zhu et L.Shu) are proposed.

El comportamiento asimétrico de los costos y gastos pegajosos (2001-2017)

Analizar el comportamiento de los costos y gastos siempre ha sido una preocupación para los usuarios de los sistemas de información financiera. En particular, a partir de 2003, existe un mayor interés por estudiar el fenómeno de la pegajosidad de los costos (sticky costs en inglés) y gastos relativos a la variación de las ventas. A fin de profundizar en el tema, nos dimos a la tarea de investigar si en México la pegajosidad durante los períodos con crisis (2008–2011) es diferente a la de los períodos sin crisis (2002–2007 y 2012–2017), y si la pegajosidad de los costos es asimétrica a la de los gastos. Esto se realizó a partir de una selección de 59 emisoras de la Bolsa Mexicana de Valores (BMV), utilizando un modelo de regresión probado, y se pudo validar la existencia de este fenómeno, tanto de los costos como de los gastos, y se encontró que es mayor en los costos durante los años sin crisis y mayor en los gastos en años con crisis, situaciones que requieren mayor atención.
Dynamics of ecosystem carbon in different forest types in the central Himalaya: Role of nitrogen-fixing Nepalese alder (Alnus nepalensis D. Don.)

Nitrogen-fixing Nepalese alder (Alnus nepalensis D. Don.) is a fast-growing early successional species which often forms pure stands in areas affected by landslides and sometimes it occurs mixed with other species in the central Himalayas. In this study, we assessed the distribution of ecosystem carbon storage in plants and soil in a chronosequence of A. nepalensis forest stands in central Himalaya. We examined six forest stands: (1) A. nepalensis-early regeneration (AER) forest, (2) A. nepalensis-late regeneration (ALR) forest, (3) A. nepalensis- mature oak mixed (AMOM) forest, sis tree biomass in different stand AER, APDF, ALR, AMOM, and AMR, AMOO, was 8.97, 51.41, 16.07, 53.74, 144.77, and 101.14 Mg ha-1, respectively. Soil organic C (SOC) in different soil depths in successional stages AER (0-10 cm), APDF (0-30 cm), ALR (0-100 cm), AMOM (0-100 cm), AMR (0-100 cm), and AMOO (0-100 cm) was 3.31, 31.21, 75.47, 157.04, 159.43 and 210.13 Mg ha-1, respectively, with decrease in SOC concentration with increasing soil depth. The ecosystem C storage averaged 15.85, 183, 216.26, 390.32, 403.66, and 500.08 Mg ha-1 in AER, APDF, ALR, AMOM, AMR, and AMOO sites, respectively. Overall, in A. nepalensis forest development markedly ameliorated both vegetation and soil succession in central Himalaya.
