Published: November 2020

PurposeThe purpose of this paper is to bring the attention of the intellectual capital (IC) research and practice communities to the value of IC in hotels' efforts to resolve or mitigate environmental problems over time. This research has been set to examine the relationships between key KM and IC concepts including environmental knowledge structures and exploitation and exploration of environmental knowledge (EK) as drivers of environmental organisational learning. The research has also examined the relevance of pro-environmental behavioural intention capital (PEBIC) as a component of structural capital and therefore an integral part of the intellectual capital of hotels.Design/methodology/approachThe data analysis technique used to test the proposed conceptual model is partial least squares structural equation modelling (PLS-SEM). Sample received from 87 companies from the Spanish hospitality sector in a longitudinal study (six years).FindingsThe results support that environmental knowledge structures (exploitation and exploration) has a positive impact on PEBIC over time. In other words, environmental organisational learning has the capability to create structural capital in hotel over time.Originality/valueThe research has addressed the challenges of exploration and exploitation of EK and PEBIC from a perspective not previously covered in the extant literature, further improved by the longitudinal nature of this study. Our focus on the hospitality sector makes this research relevant for management structures at numerous of hotels, as well as to their supply chains around the world. In addition, this research highlights the value to create structural capital through EK and organisational learning in the context of take care of our natural resources.

Abstract

Learning is a behavioural change based on memory of previous experiences and a ubiquitous phenomenon in animals. Learning effects are commonly life‐stage‐ and age‐specific. In many animals, early life experiences lead to pervasive and persistent behavioural changes.

There is broad consensus that learning has far‐reaching implications to biological control. Proximate and ultimate factors of individual learning by parasitoids and true predators are relatively well understood, yet the consequences of learning to higher organizational levels, populations and communities, and top‐down trophic cascades are unexplored.

We addressed this issue using a tri‐trophic system consisting of predatory mites Amblyseius swirskii, Western flower thrips Frankliniella occidentalis and whole common bean plants, Phaseolus vulgaris. F. occidentalis are notorious horticultural pests that are difficult to control. Therefore, practitioners have much to gain by optimizing biological control of thrips.

Previous studies have shown that early life experience of thrips by A. swirskii improves foraging on thrips later in life due to decreased prey recognition times and increased predation rates, together enhancing predator fecundity. Here, we hypothesized that early learning by A. swirskii enhances biological control of thrips via immediate and cascading effects. We predicted that release of thrips‐experienced predators enhances predator population growth and thrips suppression and reduces plant damage as compared to release of thrips‐naïve predators.

The behavioural changes brought about by early learning cascaded up to the population and community levels. Thrips‐experienced predators caused favourable immediate and cascading effects that could not be compensated for in populations founded by thrips‐naïve predators. Populations founded by thrips‐experienced predators grew faster, reached higher abundances, were more efficacious in suppressing an emerging thrips population and kept plant damage at lower levels than populations founded by thrips‐naïve predators. Plant fecundity correlated negatively with thrips abundance and positively with predatory mite abundance. Improved biological control was mainly due to thrips‐experienced founders providing for a head‐start in predator population growth and thrips suppression.

Synthesis and applications. Our study suggests that learned natural enemies have high potential to optimize augmentative biological control on a larger scale due to favourably modulating organizational upward and trophic top‐down cascades.
Immigrants’ net direct fiscal contribution: How does it change over their lifetime?

Published: November 2020

AbstractLife‐cycle direct public fiscal contributions and transfers are studied using longitudinal income tax data from 1982 to 2016 and administrative files for immigrants landed in Canada from 1980 to 2016. Relative to a comparison group comprising the Canadian‐born and immigrants landed before 1980, immigrants since 1980 have a lower average net direct fiscal contribution (NDFC) during their working years due to their lower taxes and social security contributions but a higher average NDFC after 65 years of age because of reduced public pension eligibility and entitlement. Immigrants who landed at younger than 19 years old have much higher direct fiscal contributions than other age‐at‐arrival groups and reach their peak of contributions around 10 years earlier in life than other age‐at‐arrival groups. Immigrants whose age at arrival is above 65 have a less negative average NDFC than other age‐at‐arrival groups over the above‐65 life cycle. These life‐cycle age𠄁at‐arrival trajectories are stable for immigrants in different landing cohorts. We apply the life‐cycle estimates to project the present discounted value of lifetime NDFCs for immigrants who landed in 2016. For each landing age group, refugees and family class immigrants have negative or zero average present values of life‐cycle NDFCs, much below that of economic immigrants.

AbstractThe programmed cell death‐1/programmed cell death‐ligand 1 (PD‐1/PD‐L1) pathway is involved in preventing immune system‐mediated destruction of malignant tumors including glioblastoma. However, the therapeutic influence of PD‐1/PD‐L1 inhibition alone in glioblastoma is limited. To develop effective combination therapy involving PD‐1/PD‐L1 inhibition, we used a non‐replicating virus‐derived vector, hemagglutinating virus of Japan‐envelope (HVJ‐E), to inhibit tumor cell PD‐L1 expression by delivering siRNA targeting PD‐L1. HVJ‐E is a promising vector for efficient delivery of enclosed substances to the target cells. Moreover, HVJ‐E provokes robust antitumoral immunity by activating natural killer (NK) cells and cytotoxic T lymphocytes (CTLs), and by suppressing regulatory T lymphocytes (Treg). We hypothesized that we could efficiently deliver PD‐L1‐inhibiting siRNAs to tumor cells using HVJ‐E, and that synergistic activation of antitumoral immunity would occur due to the immunostimulating effects of HVJ‐E and PD‐1/PD‐L1 inhibition. We used artificially induced murine glioma stem‐like cells, TS, to create mouse (C57BL/6N) glioblastoma models. Intratumoral injection of HVJ‐E containing siRNA targeting PD‐L1 (siPDL1/HVJ‐E) suppressed the expression of tumor cell PD‐L1 and significantly suppressed tumor growth in subcutaneous models and prolonged overall survival in brain tumor models. Flow cytometric analyses of brain tumor models showed that the proportions of brain‐infiltrating CTL and NK cells were significantly increased after giving siPDL1/HVJ‐E; in contrast, the rate of Treg/CD4+ cells was significantly decreased in HVJ‐E‐treated tumors. CD8 depletion abrogated the therapeutic effect of siPDL1/HVJ‐E, indicating that CD8+ T lymphocytes mainly mediated this therapeutic effect. We believe that this non‐replicating immunovirotherapy may be a novel therapeutic alternative to treat patients with glioblastoma.
Nowhere to hide: The importance of instream cover for stream‐living Coastal Cutthroat Trout during seasonal low flow
Authors: Penaluna Brooke E. , Dunham Jason B. , Andersen Heidi V. 
Published: November 2020

AbstractThrough their multiple functions, refuges may be important for stream‐living fishes, particularly during stressful events such as seasonal low flow or drought. Coastal Cutthroat Trout Oncorhynchus clarkii clarkii is an ideal study organism to understand the importance of refuge. During seasonal low flow, lower water levels limit access to refuge and emigration, survival of fish is low, and predation risk is high. Under these conditions, we studied patterns of cover use from field observations and tested predictions from multiple hypotheses about cover use in a semi‐natural experiment. Boulders were the main cover selected by trout in natural streams. Trout disproportionately used cover near deeper water, and they selected larger‐sized cover in shallower water. Trout showed plasticity to switch among behaviours, concealing under cover and emigrating as first options, followed by grouping, and then habitat shifting. Lack of feeding and growth suggested that perceived threat of predation was a more important driver of behaviour than foraging. Emigration was also linked to cover, with higher levels of emigration associated with less cover availability, revealing a potential link between refuge and demography through emigration. Except for feeding, the intensity of alternative behaviours can increase or decrease depending on refuge availability. Collectively, findings of this work indicate that cover can be considered a critical limiting resource along with other fundamental resources of food and space for stream‐living fish.
Mechanical forces and Hidradenitis Suppurativa
Authors: Boer Jurr , Jemec Gregor B.E. 
Published: November 2020

AbstractThe mechanism by which inflammatory skin disease forms localized patterns of lesions is poorly understood. Hidradenitis suppurtiva (HS) is strikingly located to intertriginous areas. These areas are subject to considerable mechanical stress (friction, pressure and shear forces). Koebner phenomenon (KP) describes the appearance of typical skin lesions of a pre‐existing dermatosis on previously clear skin following trauma, such as friction, pressure and more often penetrating injury with subsequent scarring. Striae distensae (SD) are a form of dermal scarring and can be considered as a form of inflammation‐driven dermal disarray. Ectopic HS lesions may occur as KP due to trauma and locally increased susceptibility consisting of either altered mechanical qualities or inflammation. SD and mechanical stress may thus provide a model for the development of lesions. In the absence of an (animal) model or experiment, two patients are described who show HS (‐like) lesions along co‐localized with SD. The suggested two‐hits model may be necessary for the development of KP in HS, that is that the general susceptibility, conferred by obesity, requires a local susceptibility factor to result in ectopic lesions. Ultimately, if ectopic HS lesions are considered true HS lesions it may be speculated that similar interaction occurs in the naturally stressed skin areas offering a possible explanation of the localized pattern of the disease.

AimDue to demographic change, the number of geriatric patients is still rising. Although hip fractures are the subject of current research, little is known about the remaining geriatric trauma entities. The aim of this study was to collect data of the age‐related traumatological intensive care unit (ICU) population, its underlying diagnosis, and the influence on mortality and length of stay in the ICU.MethodsGeriatric trauma patients (aged ≥65 years) treated postoperatively in our surgical ICU were included in this retrospective observational study covering the period 2013–2017. In addition to the underlying fracture entities, patient characteristics, such as age, sex, Charlson Comorbidity Index, length of stay and mortality, were collected to identify possible independent predictive factors for mortality in the ICU using multivariate analysis.ResultsDuring the observation period, 805 (60.5%) patients met the inclusion criteria. 47.6% of the patients suffered from a proximal femoral fracture. The total mortality rate during the stay in the ICU was 7.5%. Significant predictive factors for mortality in the ICU were Charlson Comorbidity Index (P < 0.001) and length of stay (P < 0.001). The different fracture types themselves were not a significant risk factor for mortality (P = 0.862).ConclusionPatients with proximal femoral fractures account for approximately half of the patients in intensive care. The mortality rate of these patients is no higher than that in geriatric trauma patients with other fractures. The progression is essentially influenced by the patient's comorbidities. Nowadays, the focus shifts from trauma care to the therapy of concomitant diseases. Nevertheless, this cohort, when adequately treated, shows a comparatively low mortality rate.

AimsThe decision to consider adjuvant chemotherapy (AC) for non‐small cell lung cancer is currently governed by clinical stage. This study aims to assess other routinely collected pathological variables related to metastasis and survival for their ability to predict the efficacy of AC in lung adenocarcinoma.Methods and resultsA retrospective single‐centre series of 620 resected lung non‐mucinous adenocarcinoma cases from 2005 to 2015 was used. Digital images of all slides were subjected to central review, and data on tumour histopathology, AC treatment and patient survival were compiled. A statistical case matching approach was used to counter selection bias. Several high‐risk pathological criteria predict both pathological nodal involvement and early death: positive vascular invasion status (VI+) (HR = 2.10, P < 0.001), positive visceral pleural invasion status (VPI+) (HR = 2.16, P < 0.001), and solid/micropapillary‐predominant WHO tumour type (SPA/MPPA) (HR = 3.29, P < 0.001). Crucially, these criteria also identify patient groups benefiting from AC (VI + HR = 0.69, P = 0.167, VPI + HR = 0.44, P = 0.004, SPA/MPPA HR = 0.36, P = 0.006). Cases showing VI+/VPI+/SPA/MPPA histology in the absence of AC stage criteria were common (170 of 620 total), and 8 had actually received AC. This group showed much better outcomes than equivalent untreated cases in matched analysis (3‐year OS 100.0% versus 31.3%). Inclusion of patients with VI+/VPI+/SPA/MPPA histology would increase AC‐eligible patients from 51.0% to 84.0% of non‐mucinous tumours in our cohort.ConclusionsOur data provide preliminary evidence that the consideration of AC in patients with additional high‐risk pathological indicators may significantly improve outcomes in operable lung adenocarcinoma, and that AC may be currently underused.
Pre‐transurethral prostate resection anxiety on postoperative pain and sleep quality: A correlational study
Authors: Atay Seda , Aydin Sayilan Aylin 
Published: November 2020

AbstractDoes pre‐transurethral prostate resection (TURP) anxiety have any effect on postoperative pain and sleep quality? This descriptive, cross‐sectional study was planned to determine the effect of pre‐TURP anxiety on postoperative pain and sleep quality in adult male inpatients scheduled for TURP surgery in a urology clinic. Studies investigating the relationship between preoperative anxiety and TURP have reported side‐effect‐related quality of sleep impairment and higher pain levels in patients. The study was completely conducted from June to December 2018. Eighty‐five participants meeting the inclusion criteria were involved. Informed consent was provided before the study outset. A patient identification form, the Surgery‐Specific Anxiety Scale (SSAS), a numerical pain scale (Visual Analog Scale, VAS) and the Pittsburgh Sleep Quality Index (PSQI) were employed. Descriptive statistical methods and parametric tests were used with NCSS 2007 software for data analysis. Significance was set at P < .05. The mean age of the patients undergoing TURP was 70.79 ± 7.40 years, the mean SSAS score was 19.79 ± 3.72, the mean postoperative VAS score was 4.65 ± 1.91 and the mean PSQI score was 6.75 ± 3.21. A statistically significant positive correlation was determined between total SSAS scores and post‐operative VAS scores (P < .01). Poor sleep quality was present in 71.8% of individuals (n = 61), but there was no significant association between preoperative anxiety and sleep quality (P > .05). Preoperative anxiety levels in patients undergoing TURP surgery positively affected pain during the post‐operative period but had no effect on sleep quality. The limitations of the present study include the time restriction in the sample selection, and the fact that the results are specific to the group involved in the research. Another limitation was the research design that obviated any conclusion being drawn concerning the cause and effect relationship between anxiety and pain and sleep quality. The effect of preventing anxiety before surgery on pain and sleep quality can be investigated in future studies.
Soil disturbance levels, soil water content and the establishment of rainfed chickpea: Mechanised seeding options for smallholder farms in north‐west Bangladesh

Published: November 2020

AbstractOptimum soil physical conditions for crop establishment are more likely to occur with mechanised row‐sowing using metered seeding and controlled depth placement of seeds than with broadcast sowing, that is common in many traditional South Asian cropping practices. Establishment success is a limitation for post‐rice crops in medium to heavy textured soils in the Eastern Gangetic Plain because sowing coincides with rapid topsoil drying and increases in soil strength. In addition, due to lack of rainfall in the post‐rice season the crop relies on access to stored soil water during vegetative and reproductive growth to achieve adequate yields. Our aim was to determine whether decreased soil disturbance (from full tillage to zero tillage (ZT) to undisturbed soil (Fallow)) and direct seeding (using small‐scale seeders) could 1) enhance chickpea crop establishment by conserving seedbed soil water and 2) alter crop water use of the water stored in the soil profile. The silt loam soil has an estimated volumetric soil water content (θv) of 34% at field capacity. At sowing, θv in the seedbed was between 25% to 29%. This was adequate for successful chickpea crop establishment, but slightly wetter than optimum for tillage. In the wet soil at sowing, there was evidence of smeared furrow walls and poor soil covering of the seed in the seedbed in strip planting (SP; rotating blades in front of tine) and ZT. Uncovered furrows (in ZT; using a tine opener) and the fallow soil lost more surface soil water (9%, 23 days after sowing) than the seedbeds created with greater levels of soil disturbance. In 2008, grain yield of single‐pass shallow tillage (SPST) was greater than SP but in 2009, grain yields of all one‐pass tillage techniques (ZT, SP, SPST) were greater than in the broadcast seeding in fully tilled soils. The improvement in chickpea yields was attributed to greater plant numbers, early plant vigour and root growth. Chickpea roots were found to 60 cm depth in the soil profile, and soil water content was less than the θv of wilting point to this depth at podding. There is evidence that root growth and plant water uptake occur deeper in these soil profiles to achieve the grain yields > 1,000 kg/ha recorded in this study. Mechanised sowing in rows with small‐scale seeders has the capability to overcome establishment and yield limitations for chickpea on medium to heavy soils in the post‐rice season.

Published: November 2020

AbstractDinophytes are widely distributed in marine‐ and fresh‐waters, but have yet to be conclusively documented in terrestrial environments. Here, we evaluated the presence of these protists from an environmental DNA metabarcoding dataset of Neotropical rainforest soils. Using a phylogenetic placement approach with a reference alignment and tree, we showed that the numerous sequencing reads that were phylogenetically placed as dinophytes did not correlate with taxonomic assignment, environmental preference, nutritional mode, or dormancy. All the dinophytes in the soils are rather windblown dispersal units of aquatic species and are not biologically active residents of terrestrial environments.
Development of a decorticator for Buchanania lanzan nuts and its process optimization
Authors: Said Prashant Pandharinath , Jadhav Vinayak Shankar 
Published: November 2020

AbstractThe study was aimed to develop a decorticator and to standardize the process for separation kernels from nuts. The developed machine was optimized using independent parameters, that is, cold water soaking, steaming, and sand roasting, different moisture levels (7 and 9%), cylinder speed (150 and 300 rpm), and concave clearances (7.5 and 8 mm). The optimum performance of a developed decorticator was obtained when sand roasted nuts (7% moisture content) fed at a cylinder speed of 300 rpm and a concave clearance of 8 mm. At this condition, decortication efficiency, capacity, and whole kernel recovery were 96.10, 64.15, and 12.60%, respectively. The decorticator produced 126 g whole kernels (56.71%) from 1 kg of nuts. The independent process parameters have significant effect on response variables. The machine had low labor requirement, high efficiency, and ease to operate; thus, the results will be useful for processing of nuts and in other studies.Practical applicationsThe chironji nut decorticator has application to decorticate nuts to produce kernel at manufacturing site of food, flavor, cosmetic, and pharmaceutical industries. The kernels have very short shelf‐life because they are very soft and susceptible to mechanical damage and spoilage. The available decorticators have very limited efficiency and more breakage thus the results can be utilized to fill existing gap to obtain increased efficiency and less damage. The results of different treatments to nuts will assist future studies as well.
