Superior Business Performance and Corporate Culture in Latin America

Purpose – Within the framework of Resource-Based View (RBV) we evaluated the relationship between corporate culture and superior business performance in a sample of 62 Latin American firms traded on the NYSE. Design/methodology/approach – Data retrieved from 20-F forms and the CRSP database, covering the period 2011-2016, was submitted to multiple linear regression with robust errors and random effects. Findings – Our results revealed that i) the 7 Latin American countries represented in the sample displayed a very similar mix of corporate culture, with a slight predominance of the competitive type, ii) less indebted and larger firms attained higher levels of superior business performance, and iii) auditing by one of the Big Four was associated with better performance in firms with competitive and creative culture. In the multiple regression analysis, creative culture was the best explanatory factor of superior corporate performance. Thus, we conclude that a culture with an emphasis on innovation generates competitive advantage. Originality/value – The organizations should make efforts to understand and manage the dynamics of corporate culture, harnessing their own dominant culture in the quest for superior corporate performance. As posited by RBV, our results show that investment in creative and innovative culture is particularly favorable to the creation of competitive advantage and, consequently, business performance.
Evidence for 21-helicity of poly[9,9-bis(2-ethylhexyl)fluorene-2,7-diyl]

The conformational state of the π-conjugated polyfluorene poly[9,9-bis(2-ethylhexyl)fluorene-2,7-diyl] is reconsidered. Contrary to the general opinion, this helical polymer is shown to organize in a giant repeat consisting of 21 monomer units. The length of the unit cell of 16.97 nm is suggested.
PSIII-7 Evaluating sow colostrum somatic cell count as an indicator for colostrum composition or litter characteristics

Sow colostrum is essential during early piglet life to provide passive immunity via immunoglobulins and leukocytes.The somatic cell population in colostrum and milk consists of leukocytes and epithelial cells. Somatic cell count (SCC) of milk is commonly used as an indicator of cow milk quality and health status, but not commonly measured in lactating gilts or sows. An experiment was conducted to evaluate the relationship between colostrum SCC and colostrum composition or litter performance. A total of 194 frozen (-20℃) colostrum samples from Large White × Landrace females were evaluated for SCC. Cells were pelleted and washed twice by centrifugation (10 min. at 400 x g; 4℃) in Phosphate Buffered Saline (PBS; pH 7.2, LifeTechnologies). The resulting cell sample was labelled with a nuclear dye (LDS751) and cells counted via micro-capillary bench-top flow cytometer (Guava EasyCyte Plus, Millipore). Final SCC (cells/mL) was calculated by dividing sample cell count (cells/sample) by original sample volume (mL/sample). Data was analyzed for relationship between SCC and response variables using Pearson correlation. A pairwise comparison was used to evaluate SCC by parity category (gilts vs. sows). Results were considered significant at P< 0.05. Final somatic cell counts ranged from 5.8×104 to 2.9×106 cells/mL. Sows had decreased (P=0.033) SCC compared to gilts (3.0 ×105 vs. 3.7 ×105). There was no evidence for a relationship (P >0.05) between SCC and piglet weight at 24h or weaning, 24h litter gain, 24h or pre-wean mortality, sow backfat or body weight. Colostrum total solids, protein, lactose, and immunoglobulin G concentration showed no evidence for relationship (P >0.05) to SCC. Colostrum fat showed a weak positive correlation (P=0.018, R=0.18) with SCC. In conclusion, colostrum SCC is lower in sows than gilts, but does not appear to correlate to colostrum composition or litter performance.
IMPROVING YIELD AND QUALITY IN SPRING-SOWN ALFALFA WITH ANNUAL COMPANION CROPS

Under spring sowing condition, alfalfa (A) was intercropped with sorghum-sudangrass (SR), maize (M), soybean (S), cowpea (C) and buckwheat (B) as binary mixtures with three seed ratio (A:X%; 100:100, 100:80, 100:60%) and, results were compared to alone alfalfa. Removing companion crops from stand was different times based on their stages and decided mainly considering forage quality and animal consumption. The experiment was arranged as a randomized block design with three replications in Yozgat-Turkey. Data including yield, protein and mineral content were collected in the establishment (2014) and first production year (2015). Intercropping, particularly those containing maize and sorghum, caused significantly (p<0.05) higher hay and protein yield in both separate and combined years compared to alone seeded alfalfa. According to two-years results, total hay and protein yield of alone alfalfa determined as respectively 3294.92 kg da-1 and 793.04 kg da-1. In combined years, intercropped A with SR at 100:80% (4377.70 kg da-1), 100:60% (4249.14 kg da-1) and with M at 100:80% (4307.21 kg da-1) were the highest yielding treatments for hay. Similarly, protein yield was determined the highest in the treatments of 100A:80SR% (942.70 kg da-1) and 100A:80M% (949.09 kg da-1). So, maize and sorghum-sudangrass at 80% seed ratio was the best companion crops for alfalfa in the present conditions.
Chemotherapy-Induced Peripheral Neurotoxicity as A Risk Factor for Poor Sleep Quality in Breast Cancer Survivors Treated with Docetaxel

Objective: The purpose of this study was to explore sleep quality and to determine whether chemotherapy-induced peripheral neurotoxicity is a risk factor for poor sleep quality in breast cancer survivors who receive docetaxel treatment. Methods: Secondary data analysis from a cross-sectional study. Sample characteristics were collected using an information sheet. Independent variables included the Hospital Anxiety and Depression Scale (HADS), the Patient Neurotoxicity Questionnaire (PNQ), and the Identification Pain Questionnaire (ID pain). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). We performed descriptive analyses and simple logistic regression. Results: A total of 98 participants were included. More than 60% of them reported poor sleep quality, with their average PSQI score being 7.54 ± 4.45. Poor subjective sleep quality (1.37 ± 0.88) and short sleep duration (1.37 ± 1.08) were their main problems. In addition, significant risk factors for poor sleep quality were chronic illness (odds ratio [OR] = 2.753, P = 0.041), anxiety (OR = 7.714, P = 0.009), neuropathic pain (OR = 11.261, P = 0.022), sensory neuropathy (OR = 2.529, P = 0.032), motor neuropathy (OR = 3.781, P = 0.002), and undergoing chemotherapy (OR = 2.593, P = 0.027). Targeted therapy that some survivors received served as a protective factor (OR = 0.351, P = 0.015). Conclusions: We found a high prevalence of poor sleep quality in breast cancer survivors treated with docetaxel. The results indicated that, in addition to clinical characteristics and psychological discomfort, chemotherapy-induced peripheral neurotoxicity is a significant risk factor for poor sleep quality.

Electrosprayed Nanoparticles Based on Hyaluronic Acid: Preparation and Characterization

Modern drug delivery systems demand the development of targeted polymer-carriers with the set of obligatory requirements. Thus, such capsules must have total biocompatibility, biodegradability, and possess non-allergenic, and non-tumorigenic properties. Hyaluronic acid (HA), as a natural linear polysaccharide that is included in the pericellular and extracellular matrixes, satisfies all these demands in the best possible way. In this study, the biopolymer nanoparticles with an average diameter of 300 nm were successfully obtained from aqueous HA solutions by electrospraying technique and characterized. Due to the presence of active functional groups in the structure of HA, such polymer particles can incorporate various pharmaceutical agents. This finding expands the investigation and subsequent application of drug-loaded nanoparticles based on HA as challenging and advanced targeted delivery systems.
Big data, accessibility and urban house prices

Big data applications are attracting increasing interest among urban researchers. One unexplored question is whether the inclusion of big data accessibility indices improves the accuracy of hedonic price models used for residential property valuation. This paper compares a big data index with an index derived from a regional travel demand model developed by local transportation planning agencies and traditional measures of accessibility defined as distances to employment centres. Controls for submarkets and a combined spatial autoregressive and spatial error model are also assessed as tools for capturing the value of location. Using single-family residential transactions from the Miami, Florida, metropolitan area, the study’s main conclusion is that the big data accessibility measure does not add meaningful explanatory or predictive power. In contrast, the spatial autoregressive and error model outperforms the other options considered.
Varying support for abundance‐centre and congeneric‐competition hypotheses along elevational transects of mammals

Whether species are most abundant at their geographic range centre and increasingly rare towards range limits (the abundance‐centre hypothesis, ACH) has weak empirical support in birds along elevational gradients. This may be due to empirical limitations—most studies do not capture the multi‐faceted nature of elevational gradients or species interactions. We examine the ACH and an alternative that the abundance maximum of elevational sympatric congeners will occur at different elevations along a gradient (the congeneric‐competition hypothesis, CCH).
SOURCES OF VARIATION IN MINERAL COMPOSITION OF SELECTED PLANTS INHABITING A FLOODPLAIN AT THE SAVANNAH RIVER PLANT

Using optical emission spectrometry, we analyzed, in triplicate, 56 leaf samples, representing nine plant species from a Savannah River Plant flood plain (partially swampy), for 19 mineral elements. Each sample for trees represented a single tree. Unless the concentration of an element was very low, most of the variation for a given plant species was between samples. The analytical coefficient of variation (CV) was less than 10 percent for the mean of all elements for some species, and the analytical CV differences from species to species were statistically significant. The total CV also varied from element to element within species and was independent of analytical CV. Collection of each sample from a different plant (the trees) resulted in a higher CV. Barium concentrations in leaves were consistently higher than those of strontium in contrast to samples from western plants. All samples were high (500 to 3000 ±g/g) in manganese, typical for podzol soils under acidic and reducing conditions. Species differences were noted for nearly every element. A somewhat elevated concentration of cobalt was found in the leaves of one species. Molybdenum was above the detection limit for only one plant species.
Role of Endoscopic Ultrasound in the Diagnosis of Pancreatic Neuroendocrine Neoplasms

Although pancreatic neuroendocrine neoplasms (PNENs) are relatively rare tumors, their number is increasing with advances in diagnostic imaging modalities. Even small lesions that are difficult to detect using computed tomography or magnetic resonance imaging can now be detected with endoscopic ultrasound (EUS). Contrast-enhanced EUS is useful, and not only diagnosis but also malignancy detection has become possible by evaluating the vascularity of tumors. Pathological diagnosis using EUS with fine-needle aspiration (EUS-FNA) is useful when diagnostic imaging is difficult. EUS-FNA can also be used to evaluate the grade of malignancy. Pooling the data of the studies that compared the PNENs grading between EUS-FNA samples and surgical specimens showed a concordance rate of 77.5% (κ-statistic = 0.65, 95% confidence interval = 0.59–0.71, p < 0.01). Stratified analysis for small tumor size (2 cm) showed that the concordance rate was 84.5% and the kappa correlation index was 0.59 (95% confidence interval = 0.43–0.74, p < 0.01). The evolution of ultrasound imaging technologies such as contrast-enhanced and elastography and the artificial intelligence that analyzes them, the evolution of needles, and genetic analysis, will further develop the diagnosis and treatment of PNENs in the future.
On Viscoelastic, Birefringent, and Swelling Properties of Laponite Clay Suspensions: Revisited Phase Diagram

Relations between thermodynamics, structural, and mechanical properties of Laponite suspensions were recently discussed in the literature. One important issue concerning the liquid/gel transition of the Laponite suspensions is to understand why a mechanical gel appears concomitantly with what appears as an incomplete nematic transition. To get some insight, we first give a more extended characterization of the viscoelastic properties of these suspensions near the liquid/gel transition. For this purpose, stress relaxation experiments are compared to direct determinations of the viscoelastic modulus in the frequency domain. This permits the following of viscoelastic properties, in the linear regime, on a very extended scale, from 10-5 to 102 rad/s. The data show that the relaxation mechanisms are very slow and are compatible with the presence of a large scale structural organization compared to the elementary particle size. The elastic modulus follows the power law: G‘ = A(C − C0)α. Only the concentration .
Botanical Extracts as Biofungicides against Fungal Pathogens of Rice

Diseases such as blast, brown spot and sheath blight considerably affect the health and productivity of rice worldwide. Chemical fungicides have been routinely used in combating these diseases; however, a safe and environmental-friendly approach using bio-fungicides is desirable in disease management of food crop such as rice. Identification of botanical extracts with antifungal potentials would be instrumental in the development of biofungicides. In this study, the antifungal potentials of Andrographis paniculata, Backhousia citriodora, and Phaleria macrocarpa against selected rice fungal pathogens were analysed. Crude extracts obtained from leaves of these plants were diluted to 5, 10, 15, and 20% and tested against Pyricularia oryzae, Exserohilum rostratum, and Rhizoctonia solani in vitro using poisoned agar method. Percentage inhibition of diameter growth (PIDG) of each crude leaf extract against test pathogens was calculated. The aqueous extract of A. paniculata showed a significant mycelial inhibitory effect against P. oryzae at 20% concentration (PIDG 81.9%) as compared to other test concentrations and pathogens. On the contrary, the aqueous extract of B. citriodora at 15 and 20% concentrations had little influence on the mycelial growth inhibition on P. oryzae and E. rostratum with PIDG values less than 50%. In addition, P. macrocarpa methanol extracts at concentration of 10% and above significantly inhibited the mycelial growth of P. oryzae, E. rostratum, and R. solani (PIDG 100%). Phaleria macrocarpa leaf extract had been identified Mui Yun Wong, Sathyapriya Hamid, Nor Afifah Iskandar Shah and Nurul Husna Ab Razak 458 Pertanika J. Trop. Agric. Sc. 43 (4): 457 466 (2020) to give the highest efficacy against all three rice pathogens in vitro and therefore, has the potential to be developed into a biofungicide as a safe alternative to synthetic fungicides for disease management of rice.
Potential Association between Kaposi Sarcoma and Gout: An Exploratory Observational Study

Background Kaposi sarcoma is a rare vascular mesenchymal neoplasm, associated with Human Herpes Virus 8 (HHV8). Gout is a condition clinically characterized by recurrent flares of arthritis and hyperuricemia. Following our clinical impression that patients with classical Kaposi sarcoma (CKS) have a high rate of gout, we explored this in a retrospective manner. Methods All consecutive patients diagnosed with sarcoma or carcinosarcoma within a single tertiary center between 1/2012–12/2017 were identified through the pathology department database. A cohort of CKS patients was compared with the non-Kaposi sarcoma and carcinosarcoma cohort. Data were extracted from patients' electronic medical records. Patients younger than 18 and patients without clinical data available were excluded. Association between diagnosis of gout and CKS was assessed and adjusted for risk factors. Results Three hundred and sixty-one patients were eligible for this analysis, 61 were diagnosed with CKS and 300 with other types of sarcoma. We found a higher incidence of gout in CKS patients, 11/61 (18%) patients, compared with 8/300 (2.6%) with other types of sarcoma, odds ratio (OR) 8.0 (P < 0.00001). This association persisted when adjusted for age >39 years (OR = 6.7, P < 0.00001), age and male sex (OR = 4.97, P < 0.0001), and when adjusting for multiple confounding factors and medical comorbidities. Conclusions We have demonstrated a statistically significant association between gout and CKS. As risk factors for gout were accounted for, this association may be explained by HHV8 immune-related effects. This should be further explored in vitro and in population-based studies.
The relationship between school principals’ social-emotional education leadership and teachers’ organizational trust and job performance

ABSTRACT In this study, the relationships between school principals’ social-emotional education leadership, and teachers’ organizational trust and job performance are examined according to the teachers’ perceptions. For this purpose the study was designed in correlational survey model. The sampling group was 215 teachers working in 14 different secondary schools. Social-Emotional Education Leadership Scale, Organizational Trust Scale and Job Performance Scale were used as data collection tools. The relationship between variables was determined by using correlation analysis and structural equation model. The findings revealed a positive and high-level relationship between school principals’ social-emotional education leadership and teachers’ organizational trust. School principals’ social-emotional education leadership behaviors positively affect both organizational trust and job performance of teachers. The findings also revealed a statistically significant relationship between teachers’ organizational trust level and job performance. However, organizational trust does not have a mediating role in relationship between school principals’ social-emotional education leadership and teachers’ job performance. Based on the findings, it can be suggested that school principals’ should foster high-level social-emotional education leadership behaviors to effect positively teachers’ organizational trust and job performance.
Behavioural Determinants of Green Managerial Practices: A Study on Bangladeshi Bankers

The study aims to determine the influential factors behind the choice of green actions by the banking employees of Bangladesh. Hypotheses and a research framework are developed with a view to explore the relationship of green managerial choice of bankers with perceived green knowledge, peer pressure, rewards and recognition and government regulations in ensuring environmental performance. A self-administered questionnaire was utilized for collecting primary data and exploratory factor analysis was tested to verify the variance of the considered variables and finally multiple-regression analysis was used to comprehend the relationship among the variables. A positive relationship was identified with peer pressure and rewards and recognition that may influence the employees to accept the overall green policies and practices. The study can help the business administrators to identify the dominating factors and work on these factors to motivate the employees to increase their environmental behaviour so that organizational environmental performance can be enhanced.
Distinguishing between dispersal and vicariance: A novel approach using anti‐tropical taxa across the fish Tree of Life

Anti‐tropical taxa are species split by the tropics into disjunct northern and southern populations. These distributions occur throughout the Tree of Life, but the mechanisms proposed to drive this pattern are debated and generally fit into two categories: dispersal and vicariance. Here, we quantitatively test the prevalence of dispersal and vicariance as plausible drivers of anti‐tropical marine distributions using intraspecific anti‐tropical marine fishes as a model system.
Strain rate dependent formulation of the latent heat evolution of superelastic shape memory alloy wires incorporated in multistory frame structures

Due to their unique hysteretic energy dissipation capacity, shape memory alloy (SMA) wires are particularly interesting for the development of new-type of intelligent vibration control systems for structures. However, in structural control, most of the vibrations occur in high strain rate regimes, which interfere the release of self-generated heat and thus influence the hysteretic dissipation. This paper proposes a strain rate dependent formulation of the latent heat evolution and aims to improve the accuracy of existing macroscopic modeling approaches developed for SMA wires particularly for the dynamic load cases. The proposed formulation is determined phenomenologically and implemented in a continuum thermomechanical framework based constitutive SMA wire model without impairing the simplicity and robustness of the solution process. The proposed formulation is validated by cyclic tensile tests conducted on SMA wires. Results show that the calculations using the formulation can predict the wire response more accurately than the strain rate independent formulation. For the simulation of multistory frame structures incorporating multiple SMA wires, the governing equations are driven. Shaking table tests are conducted on a 3-story frame structure under harmonic and seismic excitation. The responses of the structure are successfully replicated using the strain rate dependent latent heat formulation.
