Filogeografia de Curatella americana L. (Dilleniaceae): uma espécie arbórea das savanas da Amazônia e Brasil Central

Mudancas ambientais em savanas neotropicais parecem ter sido espacialmente complexas durante o quaternario. A dinâmica dessas mudancas e pouco conhecida, principalmente quanto a manutencao e extensao que a vegetacao de cerrado alcancou em periodos mais secos no passado. Neste estudo foi investigada a estrutura filogeografica de populacoes de Curatella americana, uma especie arborea tipica dos cerrados que ocorrem no Brasil central e Amazonia, por meio da analise de oito locos de microssatelites e duas regioes nao codificadoras do genoma do cloroplasto (cpDNA). Foram amostrados 275 individuos, de C. americana pertencentes a 22 populacoes distribuidas em areas de cerrado situadas na Amazonia e no Brasil central. Foram estimados parâmetros de diversidade genetica, bem como determinadas a estrutura genetica e as relacoes entre os haplotipos encontrados nas populacoes de C. americana. A distribuicao da variabilidade genetica dentro e entre as populacoes foi definida por meio de uma Analise de Variância Molecular (AMOVA), a qual mostrou que aproximadamente 70% da variacao genetica observada esta contida dentro das populacoes. O indice medio de diversidade genetica foi alto (He = 0.67), variando de He = 0.924 a He = 0.167 na analise dos locos cpSSR. Para as regioes nao codificadoras do cpDNA foi identificada variacao em apenas tres populacoes. A analise combinada dos oito locos de microssatelites do genoma do cloroplasto mostrou um total de 34 haplotipos, enquanto para as sequencias do cpDNA foram observados tres sitios polimorficos os quais evidenciaram quatro haplotipos. A estrutura genetica populacional evidenciada por ambos marcadores do genoma do cloroplasto, regioes nao codificadoras (FST = 0.28) e microssatelites (FST = 0.30), demonstrou uma diferenciacao genetica moderada entre as populacoes de C. americana. Tambem foi observado o compartilhamento de haplotipos entre varias populacoes de C. americana ao longo de sua distribuicao. A ocorrencia de haplotipos comuns presentes na maioria das populacoes, tanto na Amazonia quanto no Brasil Central, sugere uma recente expansao populacional da especie, corroborada por testes de neutralidade. Dessa forma a atual estrutura genetica das populacoes de C. americana evidencia a possivel influencia que eventos historicos e fluxo genico a longas distâncias provavelmente tiveram na distribuicao da variabilidade genetica nas populacoes desta especie.
Prediction of the road pavement condition index using stochastic models

Mathematical models for prediction of road network condition based on the so-called Markov chains are presented in this article. The data for calculation of elements of the transition matrix from one condition to another are taken from visual evaluation as well as from instrumental reading. It is recommended to prepare data sets in the form of pavement management system data tables based on a representative sample of measuring sections. Discrete time intervals – of one year – are used when constructing the model of transition matrices. The procedure of forming Markov transition matrix with partially complete data sets is proposed also in paper. The basis of this procedure is information on the previous condition of the structure and the results of the instrumental evaluation, which enables correction of the predicted values. The final matrix takes into account not only the probability, but also the speed of transition from one condition to another. It is also possible to work with the initial data using appropriate databases or other software.
Cryptic and cumulative impacts on the wintering habitat of the endangered black-faced spoonbill (Platalea minor) risk its long-term viability

SUMMARY The East Asian–Australasian flyway contains some of the most threatened habitats in the world, with at least 155 waterbird species reliant on the tidal habitats it comprises. The black-faced spoonbill (Platalea minor) is an iconic endangered species distributed across the coast of East Asia. Its population suffered a severe decline into the 1990s, but extensive monitoring and conservation interventions have aided a substantial recovery of the species. We used a population viability analysis based on data collected over the past two decades in conjunction with species distribution models to project spatially explicit models of population change for the next 35 years. Over nearly all scenarios of habitat loss and climate change, the global spoonbill population was projected to increase in the short-term due to low population numbers likely well below current population carrying capacities. However, climate change and habitat loss together threaten the recovery of the spoonbill population such that, by 2050, population declines are apparent as a consequence of these cumulative impacts. These threats are also cryptic and represent a challenge to the conservation of species recovering from anthropogenic impacts; observed population increases can hide large reductions in habitat suitability that threaten the long-term viability of species.
Combining ability and gene action analysis for yield and yield attributing traits in rice (Oryza sativa.L)

Six lines and four testers were involved in the combining ability and gene action study in line x tester mating design to discern desirable general and specific combiner for breeding programme. The combining ability variance indicated that sca variance was higher than gca variance indicating the preponderance of non-additive gene action for the characters studied viz., days to 50 percent flowering, panicle length, plant height, the number of grains per panicle, the number of tillers per plant, the number of productive tillers per plant, flag leaf length, flag leaf breadth, spikelet fertility, test weight and single plant yield. Among the parents, Improved White Ponni, RG192, RG163 and RG105 were discovered as the best general combiners for single plant yield. The cross combinations viz., ADT37 X RG163, ADT43 X RG105, ADT45 X RG163, ADT(R)48 X RG105, CO51 X Kavuni and Improved White Ponni X RG192 were the ideal specific combiners for single plant yield. Therefore, the aforementioned cross combinations may be employed in the upcoming breeding programmes in order to develop a higher heterosis for yield.
Distribution of economically important fish larvae (Characiformes, Prochilodontidae) in the Central Amazonia, Brazil

The spatio‐temporal patterns of three species of Prochilodontidae larvae that are intensely used as fishery resources in Central Amazonia are analysed. Sampling was conducted during 2011 at four stages of the hydrological cycle (flood, high water, falling and low water phases). Sixteen collecting stations were located in different habitats (mouths of lake channels, “barrancos,” sandbars and the main river channel) along the Solimoes and Japura rivers. A total of 4,322 Prochilodontidae larvae were collected during this investigation, with most captures occurring in the Japura River (76.3% of larvae), while only 23.7% of the samples were caught in the Solimoes River. Most captures occurred during rising water, indicating a strong reproductive seasonality in these three species. Rainfall and water level, along with dissolved oxygen, water temperature and electric conductivity, determined the larvae's spatio‐temporal distribution. These results confirm the importance of varzea areas along white water rivers for the conservation, preservation and maintenance of heavily used fishery resources in the Brazilian Central Amazonia.

Acute exposure to an electric field induces changes in human plasma lysophosphatidylcholine (lysoPC)-22:4 levels: Molecular insight into the docking of lysoPC-22:4 interaction with TRPV2

Medical treatment using high-voltage electric potential (HELP) devices to generate an electric field (EF) is an alternative therapy commonly used in Japan. However, the underlying mechanisms of the potential health benefits are not fully understood. To address this issue, we investigated the levels of lyso-form phospholipids using selected reaction monitoring (SRM) analysis in plasma samples obtained from healthy human subjects before and after a single HELP exposure (9 kV/electrode + 9 kV/electrode, 30 min). Lysophosphatidylcholine (lysoPC)-22:4 was significantly upregulated after HELP exposure. However, there was no effect on the levels of lysophosphatidic acid (lysoPA), or other lysoPC species. LysoPC is known to accelerate intestinal movement as a putative endogenous activator of transient receptor potential vanilloid 2 (TRPV2). We further examined the in silico docking simulation of lysoPC-22:4 with TRPV2. Docking results showed that lysoPC-22:4 has good binding energy (-8.2 kcal/mol). Our findings provide new insight into the molecular mechanisms of constipation alleviation by EF therapy.
Identity leadership and well-being: team identification and trust as underlying mechanisms

PurposeThe purpose of the present research was to examine the impact of identity leadership on employees' well-being mediated by team identification and trust in the leader.Design/methodology/approachIn study 1, N = 192 employees participated in a cross-sectional online survey measuring identity leadership, team identification, trust in the leader and well-being (i.e., job satisfaction, work engagement, burnout). In study 2, N = 72 university students participated in a vignette study that manipulated high/low identity leadership and tested its effect on team identification and trust in the leader.FindingsIn study 1, identity leadership predicted higher team identification, trust in the leader and well-being of employees. Team identification mediated the positive relationship of identity leadership with both job satisfaction and work engagement, while trust in the leader mediated the negative relationship of identity leadership with burnout. In study 2, team identification and trust in the leader were significantly higher in the high identity leadership condition.Research limitations/implicationsThe findings are consistent with the few existing studies on the positive effects of identity leadership. However, due to the correlational nature of the data in study 1, future longitudinal field research is needed to support the current findings and further establish causality for the model as a whole.Practical implicationsIdentity leadership seems to be promising to increase well-being among employees. Thus, leadership development programs to foster identity leadership and collective identity should be implemented in organizations and further tested with respect to well-being.Originality/valueThis research contributes to an emerging body of research on the social identity approach to leadership and supports the recent claims that social identity might be one of the links between leader behavior and well-being of employees. Moreover, this study is among the first to investigate and experimentally test the underlying mechanisms of identity leadership.
Assessing the efficiency of UV LEDs as light sources for sampling the diversity of macro-moths (Lepidoptera)

Light trapping is the most widely used tool for determining the diversity of nocturnal Lepidoptera, but UV LEDs have yet to be used as light sources for the large-scale monitoring of Lepidoptera. We assessed the efficiency of this novel light source for sampling moths using a Heath type moth equipped with a strip of 150 high brightness UV LEDs (emission peak 398 nm, ~ 15 W) powered by a 12 V battery. We compared the number of individuals, the number of species and the Geometridae / Noctuidae ratio recorded for the samples collected using UV LED traps with those collected in two monitoring programs carried out in the same geographic region using two different light sources: a 200 W incandescent lamp (Rothamsted trap) and a 160 W mercury vapour lamp (manual catch). The total catch consisted of 61,120 individuals belonging to 699 species. The species richness rarefaction curves revealed that the Rothamsted trap collected fewer species and individuals than UV LED traps. Furthermore, the median numbers of species and individuals caught by UV LED traps fell within the range of those caught by mercury vapour lamp traps. In addition, the community composition recorded using incandescent lamps and UV LEDs was similar. The data obtained using UV LED traps, in absolute terms and in comparison with the other light sources and different sampling methods, clearly reveal that this light source is suitable for sampling macro-moth communities. For field work UV LEDs have many advantages, as they are resistant to mechanical damage, easily protected from heavy rain and energy efficient.
Effect of Supplementation of Formaldehyde Treated Mustard Oil Cake on Feed Intake, Growth Rate, Blood Biochemical and Mineral Constituents in Hariana Heifers

A growth trail was conducted with 24 Hariana cattle heifers of 12-16 months old, weighing about 150 kg to study the effect of feeding formaldehyde treated mustard oil cake based diet on feed intake, growth performance, nutrient utilization, certain mineral absorption and serum biochemical parameters. Animals were randomly divided into four groups of 6 animals each and were individually fed for a period of 120 days. The animals in group I was fed with diet containing 80% crude protein of NRC, group II were fed with diet containing 100% crude protein of NRC, group III were fed with formaldehyde treated mustard cake diet containing 80% crude protein of NRC and group IV were fed with diet containing formaldehyde treated mineral fortified mustard cake containing 80% crude protein of NRC. Average daily body weight gain (g/d) of animals in group IV was significantly (p<0.05) higher in comparison to group I, but statistically similar with group II. Absorption of minerals (Ca, Mg, Cu, Fe, Zn, Mn and Se) were statistically similar except P, which was significant (P<0.01) higher in group II than that of other groups. Higher concentration of serum Zn in group II, while the serum Ca level increased significantly for all the groups as the trial progressed. Incorporation of formaldehyde treated mustard oil cake in the concentrate mixture led to increase in growth rate by 23.5% due to better balance of nutrients. Thus, it may be concluded that formaldehyde treatment of mustard cake is beneficial in growing heifers without any stress as assessed by serum biochemical constituents, enzymes activities and mineral profile.
CDK5 Inhibition Abrogates TNBC Stem‐Cell Property and Enhances Anti‐PD‐1 Therapy

Triple‐negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, in which the higher frequency of cancer stem cells (CSCs) correlates with the poor clinical outcome. An aberrant activation of CDK5 is found to associate with TNBC progression closely. CDK5 mediates PPARγ phosphorylation at its Ser 273, which induces CD44 isoform switching from CD44s to CD44v, resulting in an increase of stemness of TNBC cells. Blocking CDK5/pho‐PPARγ significantly reduces CD44v+ BCSCs population in tumor tissues, thus abrogating metastatic progression in TNBC mouse model. Strikingly, diminishing stemness transformation reverses immunosuppressive microenvironment and enhances anti‐PD‐1 therapeutic efficacy on TNBC. Mechanistically, CDK5 switches the E3 ubiquitin ligase activity of PPARγ and directly protects ESRP1 from a ubiquitin‐dependent proteolysis. This finding firstly indicates that CDK5 blockade can be a potent strategy to diminish stemness transformation and increase the response to PD‐1 blockade in TNBC therapy.
An in-Depth Exploration of EFL Teachersâ€™ Grammar Teaching Cognition

L2 research, during the last two decades, has almost abandoned studying appropriacy of methodologies and techniques to focus more on the underlying derives for teachersâ€™ pedagogical decision makings inside the class. Borgâ€™s (2003) ideas of the role of teachersâ€™ cognition in their adaptation and adoptation of teaching techniques and activities have noticeably influenced L2 professional research community. This study, in line with the recent trend, is designed and conducted to elicit EFL teachersâ€™ grammar teaching cognition to have more comprehensive accounts of teachersâ€™ behaviors in the class. In so doing, a Likert scale 25-item questionnaire developed by Naashia (2006) was administered to 177 Iranian EFL teachers. The results indicated that EFL teachers are currently more inclined toward communicative focus on grammar in which grammar instruction is marginalized to have learners naturally act out linguistics rules while performing communicative tasks.

A Narrative Review of the Needs of Children in Foster and Kinship Care: Informing a Research Agenda

Abstract As a result of maltreatment, children in care can present with a range of complex needs and challenges. In addition to direct clinical care commonly provided by paediatricians, psychiatrists, and clinical psychologists, the provision of knowledge and skills to foster and kinship carers have become modes of support common in responding to these needs and challenges. A narrative review of key systematic reviews and empirical research was conducted to assess the effectiveness of existing foster carer interventions. Results indicated a range of methodological characteristics that limit our ability to develop a sound, research-driven, evidence base. As a result, we remain limited in our knowledge about which treatments are effective, for which symptoms they are effective, and for which population subgroups they are most likely to be effective. This review provides a summary of identified needs and challenges in the delivery of foster carer interventions. It provides an account of current treatment components and offers a platform for the development and progression of a programme of research in an effort to advance knowledge in the area.
Investigating the Core–Periphery Relationship in the Southern African Customs Union

This study explores the relevance of the core–periphery relationship in the Southern African Customs Union (SACU), a union comprising five highly unequal economies. In the analysis, the study employs five key indicators: economic size, trade logistics and facilitation, regional integration, and intra-SACU trade, to assess the main aspects underlying the core–periphery relationship in the union. The findings of this study point to dominance-dependency behavior within the union, where South Africa is the dominant core while Botswana, Lesotho, Namibia, and eSwatini are the dependent periphery. Based on the findings, the recommendations are that SACU countries should, among other strategies, identify ways of promoting high-value-added cross-border value chains across the union members. Also, the Botswana, Lesotho, Namibia, and eSwatini peripheries could improve their infrastructure and productive capacity if their objective is to create an export base in some of the products currently supplied by South Africa.
On the pathogenicity of entomopathogens to the peach fruit fly, Bacterocera zonata (Saunders) (Diptera: Tephritidae).

A study to evaluate the pathogenicity of entomopathogenic nematodes and fungi against the peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae) was carried out under laboratory conditions. The nematodes species tested were; Heterorhabditis bacteriophora; Steinernema carpocapsae and S. riobrave. The fungi were; Metarhizium anisopliae and Beauveria bassiana. Different concentrations were used against immature stages of B. zonata, by contact and/or soil inoculation techniques. Results showed that both Steinernema species were more effective on full-grown larvae than H. bacteriophora in contact treatment, whereas H. bacteriophora was more effective in soil, as it induced higher mortality of B. zonata pupae at both techniques. Mortality rates of B. zonata pupae increased significantly by increasing the concentration of the two tested fungi at the same time of exposure. Adult mortality was affected by soil treatments as B. bassiana treatments significantly increased mortality rates compared to M. anisopliae and control treatments. Emerged adults from treated pupae with both fungi showed mycosis on the outer surface, additionally some emerged adults showed malformation and mostly failed to emerge. Results suggested that entomopathogenic nematodes and fungi can be used as alternative tools of pesticides for controlling B. zonata after validating protocols of field conditions.
Modelling of polarization and correlation effects in the ionization of helium by antiprotons

The ionization of helium atoms by antiprotons is considered in an independent-particle model (IPM) with a model potential that accounts for polarization and binding effects of the electrons in the two-centre Coulomb potential. The model is designed to reproduce the exact ionization potential of the quasimolecular system and to allow for the existence of one bound state in the united-atom limit. We find a single-ionization cross section that is in good agreement with the results of various correlated two-electron calculations, and a double-ionization cross section that is considerably improved compared to a standard IPM calculation with a fixed atomic target potential.
Data science in economics: comprehensive review of advanced machine learning and deep learning methods

This paper provides a state-of-the-art investigation of advances in data science in emerging economic applications. The analysis was performed on novel data science methods in four individual classes of deep learning models, hybrid deep learning models, hybrid machine learning, and ensemble models. Application domains include a wide and diverse range of economics research from the stock market, marketing, and e-commerce to corporate banking and cryptocurrency. Prisma method, a systematic literature review methodology, was used to ensure the quality of the survey. The findings reveal that the trends follow the advancement of hybrid models, which, based on the accuracy metric, outperform other learning algorithms. It is further expected that the trends will converge toward the advancements of sophisticated hybrid deep learning models.
The Future of Macromarketing: Recommendations Based on a Content Analysis of the Past Twelve Years of the Journal of Macromarketing

In their essays published in the Silver Anniversary Issue (SAI) of the Journal of Macromarketing (2006), George Fisk and Mark Peterson independently outlined the current state of the discipline and made a list of visionary recommendations that would help macromarketers adapt and respond to the changing markets, marketing, and societies. These recommendations ranged from repositioning the discipline around the ideas of societal development to leading the way across disciplines toward achieving a sustainable world. Based on a thorough content analysis of the articles published in the Journal of Macromarketing since the SAI, we aim to report the extent to which macromarketing scholarship has responded to the recommendations of Fisk and Peterson. Utilizing the findings, we make a list of new recommendations that can assist macromarketers in fulfilling their mission of ‘saving the world’.
