Some personal relections on corporate challenges and research agendas

Purpose – The purpose of this commissioned paper is to offer some personal relections on sustainability within the hospitality industry. Design/methodology/approach – The paper opens by identifying sustainability as a teasing paradox for the hospitality industry and a short discussion of the characteristics of sustainability. It then explores the growing interest in corporate sustainability and offers a review of the range of academic research into sustainability within the hospitality industry literature. More generally, the authors suggest three fundamental sets of issues that currently face the industry, namely, deining sustainability within the industry, materiality and independent external assurance and sustainable consumption and the industry’s commitment to continuing economic growth. Findings – In addressing these three sets of issues, the authors make a number of suggestions. First that deinitions of sustainability within the hospitality industry can be interpreted as being constructed around business imperatives rather than an ongoing commitment to sustainability. Second that materiality and external assurance are not treated comprehensively within the industry, which undermines the credibility of the sustainability reporting process. Third that the concept of sustainable consumption and any critique of the industry’s commitment to economic growth are conspicuous by their absence in the both the research literature on sustainability and in sustainability reporting within
Waltham International Symposium: Pet Nutrition Coming of Age

Over the last 50 y there have been numerous reports of vitamin E deficiency in cats with the main cause of these deficiencies being attributed to ingestion of diets high in polyunsaturated fatty acids (PUFAs). Steatitis (“yellow fat disease”) is attributed to vitamin E deficiency and has been experimentally induced in kittens after feeding a commercial cat food with a high fish content (1) and after feeding vitamin E–deficient purified diet containing tuna oil and stripped safflower seed oil (2,3). Fish oil is a rich source of PUFAs, which are highly susceptible to oxidation, and an increased intake of fish oil has been associated with increased vitamin E requirements. Currently the minimum dietary vitamin E requirement of cats has been set at 30 IU/kg dry matter with dietary levels expected to increase 3–4 times with a diet high in PUFAs (4). To prevent vitamin E deficiency in cats fed commercially sold diets, the Association of American Feed Control Officials (AAFCO) recommends that fish oil–containing diets for cats should be supplemented with 10 IU of vitamin E for every g of fish oil per kg diet (5). However, there is no direct evidence to substantiate the latter value or the increases recommended (4,5) in adult cats. The main objective of this study was to determine the vitamin E requirements of adult cats fed high dietary levels of PUFAs from fish oil. MATERIALS AND METHODS
Characterizing magnetized plasmas with dynamic mode decomposition

Accurate and efficient plasma models are essential to understand and control experimental devices. Existing magnetohydrodynamic or kinetic models are nonlinear, computationally intensive, and can be difficult to interpret, while often only approximating the true dynamics. In this work, data-driven techniques recently developed in the field of fluid dynamics are leveraged to develop interpretable reduced-order models of plasmas that strike a balance between accuracy and efficiency. In particular, dynamic mode decomposition (DMD) is used to extract spatio-temporal magnetic coherent structures from the experimental and simulation datasets of the HIT-SI experiment. Three-dimensional magnetic surface probes from the HIT-SI experiment are analyzed, along with companion simulations with synthetic internal magnetic probes. A number of leading variants of the DMD algorithm are compared, including the sparsity-promoting and optimized DMD. Optimized DMD results in the highest overall prediction accuracy, while sparsity-promoting DMD yields physically interpretable models that avoid overfitting. These DMD algorithms uncover several coherent magnetic modes that provide new physical insights into the inner plasma structure. These modes were subsequently used to discover a previously unobserved three-dimensional structure in the simulation, rotating at the second injector harmonic. Finally, using data from probes at experimentally accessible locations, DMD identifies a resistive kink mode, a ubiquitous instability seen in magnetized plasmas.
Running head: REACTIVE CONTROL AND LABELING IN TASK SWITCHING Published in 2014 in Developmental Psychology, 50(7), 1620-1627. Cognitive control and language across the lifespan: does labeling improve reactive control?

How does cognitive control change with age, and what are the processes underlying these changes? This question has been extensively studied using versions of the taskswitching paradigm which allow participants to actively prepare for the upcoming task (Kray, Eber,& Karbach, 2008). Little is known, however, about age-related changes in this ability across the lifespan when there is no opportunity to anticipate task goals. We examined the effect of two kinds of verbal self-instruction—labeling either the task goal or the relevant feature of the stimulus—on two components of cognitive control, goal setting and switching, in children, young adults, and older adults. All participants performed single-task blocks and mixed-task blocks (involving unpredictable switching between two tasks) in silent and labeling conditions. Participants categorized bidimensional stimuli either by picture or by color, depending on their spatial position in a two-cell vertical grid. Response times revealed an inverted U-shape in performance with age. These age differences were more pronounced for goal setting than for switching, thus generalizing results obtained in situations taping proactive control to this new context forcing reactive control. Further, differential age-related effects of verbalization were also obtained. Verbalizations were detrimental for young adults, beneficial for older adults, and had mixed effects in children. These differences are interpreted in terms of qualitative developmental changes in reactive goal-setting strategies.
BSP-Net: Generating Compact Meshes via Binary Space Partitioning

Polygonal meshes are ubiquitous in the digital 3D domain, yet they have only played a minor role in the deep learning revolution. Leading methods for learning generative models of shapes rely on implicit functions, and generate meshes only after expensive iso-surfacing routines. To overcome these challenges, we are inspired by a classical spatial data structure from computer graphics, Binary Space Partitioning (BSP), to facilitate 3D learning. The core ingredient of BSP is an operation for recursive subdivision of space to obtain convex sets. By exploiting this property, we devise BSP-Net, a network that learns to represent a 3D shape via convex decomposition. Importantly, BSP-Net is unsupervised since no convex shape decompositions are needed for training. The network is trained to reconstruct a shape using a set of convexes obtained from a BSP-tree built on a set of planes. The convexes inferred by BSP-Net can be easily extracted to form a polygon mesh, without any need for iso-surfacing. The generated meshes are compact (i.e., low-poly) and well suited to represent sharp geometry; they are guaranteed to be watertight and can be easily parameterized. We also show that the reconstruction quality by BSP-Net is competitive with state-of-the-art methods while using much fewer primitives.

The aim of this study was to evaluate the in vitro antioxidant effects of 12-[(2R,5R,6R)-5-hydroxy-6-methylpiperidin-2-yl]dodecan-2-one (iso-6cassine; ISO) and the anticonvulsant effects of ISO on pilocarpine-induced seizures in rats. Wistar rats were treated with 0.9% saline (i.p., control group), pilocarpine (400 mg/kg, i.p., pilocarpine group), and the association of ISO (1.0 mg/kg, i.p.) plus pilocarpine (400 mg/kg, i.p.), 30 min after administration of ISO (ISO plus pilocarpine group). After the treatments all groups were observed for 1h. The antioxidant effect of ISO on the pilocarpine model was assessed by determining the activity of glutathione peroxidase (GPx), glutathione-Stransferase (GST) and catalase (CAT) as well as the levels of reactive species (RS) and lipid peroxidation (LP). In vitro, ISO (5 μM) reduced RS and LP. ISO (1.0 mg/kg) and abolished seizures and death induced by pilocarpine in rats. ISO protected against the increase in the RS and LP levels, GST activity as well as the inhibition of GPx activity caused by pilocarpine. In addition, ISO increased the catalase activity in hippocampus of seized rats. In conclusion, the dta suggest that ISO can present anticonvulsant and antioxidant properties in the pilocarpine model of seizures in rats.
The Representation of Workingwomen in Spanish Television Fiction

During the sixties and seventies the limited presence of women in the public sphere was reflected in the restricted repertoire of roles played by female characters in television fiction (mainly those of mothers and wives). The strengthening of the feminist movement in the following decades increased and diversified the portrayals of women in the workplace, and further encouraged academic research on the social construction of working women. Despite the relevance of female professionals in current TV shows, the importance of romantic relationships and sexuality has led to a decreasing number of studies on the subject. This arti-cle summarizes the results of a study on working women in Spanish TV fiction, part of a larger project on the construction of female identities. The research uses an original methodology that combines quantitative techniques and qualitative methods (socio-semiotics) to analyse the sample of 709 female characters. The results show a coexistence of the traditional stereotypes of working women in customer service and care-giving positions with those of highly skilled female professionals. However, the empowerment of women in positions of responsibility is often associated with a negative portrayal of the character, while the problems of reconciling family and work are systematically avoided.
Seed germination after fire: a study with a plant inhabiting non-fire-prone areas

Resumen. Despues del fuego, la germinacion de semillas que poseen tegumento duro puede aumentar. En el presente estudio investigamos si la germinacion de semillas de Mimosa bimucronata (DC.) Kuntze (Fabaceae), cuyos tegumentos son duros, aumenta despues del fuego, a pesar de que estos arboles por lo general son de areas humedas, donde el fuego es un evento raro. Los incendios fueron provocados en bandejas llenas de tierra cubierta con cantidades diferentes de pasto seco, caracterizando tres tratamientos: a) 0g (grupo control); b) 300g, y c) 450g de pasto seco. Las semillas fueron localizadas en la superficie o enterradas en el suelo que iba a ser quemado. Los experimentos de germinacion fueron realizados en los tiempos 0-h y 24-h despues del fuego para obtener los porcentajes y el Indice de Velocidad de Germinacion (IVG). Los resultados mostraron que para el grupo control y para el grupo con 300g de pasto seco la germinacion de las semillas enterradas fue significativamente mayor que en el grupo con 450g de pasto. Por otra parte, el IVG fue significativamente mas alto con el tratamiento de 300g. No se observaron diferencias significativas entre los tiempos 0-h y 24-h. Las semillas colocadas en la superficie del suelo no sobrevivieron a la quema. Nuestro estudio mostro que aunque las temperaturas alrededor de 100 °C disminuyen significativamente la capacidad germinativa de las semillas de M. bimucronata, cuando fueron enterradas el porcentaje de germinacion no fue diferente entre el grupo control y el tratamiento con 300g. Los resultados tambien sugieren que temperaturas alrededor de 60 °C pueden aumentar la velocidad de germinacion de las semillas de M. bimucronata.
Phosphoenolpyruvate Carboxykinase Assayed at Physiological Concentrations of Metal Ions Has a High Affinity for CO2 1

The effect of Mn /Mg concentration on the activity of intact, homogeneous phosphoenolpyruvate carboxykinase (PEPCK) from leaves of the C4 grass, Guinea grass (Panicum maximum), have been investigated. Assay conditions were optimized so that PEPCK activity could be measured at concentrations of Mn /Mg similar to those found in the cytosol (low micromolar Mn and millimolar Mg ). PEPCK activity was totally dependent on Mn and was activated at low micromolar concentrations of Mn by millimolar concentrations of Mg . Therefore, at physiological concentrations of Mn , PEPCK has a requirement for Mg . Assay at physiological concentrations of Mn /Mg led to a marked decrease in its affinity for ATP and a 13-fold increase in its affinity for CO2. The Km (CO2) was further decreased by assay at physiological ATP to ADP ratios, reaching values as low as 20 m CO2, comparable with the Km (CO2) of ribulose 1,5-bisphosphate carboxylase-oxygenase. This means that PEPCK will catalyze a reversible reaction and that it could operate as a carboxylase in vivo, a feature that could be particularly important in algal CO2-concentrating systems.
The spectrum of malignancies presenting with neurological manifestations: A prospective observational study

Introduction: A neurological consultation is needed in nearly 45% of patients suffering from cancer. The present study was planned to evaluate the clinical, radiological and histopathological spectrum of patients with an underlying malignancy and presenting with a neurological complaint. Materials and Methods: We prospectively evaluated all patients provisionally diagnosed either with a primary or secondary malignancy of the brain on the basis of clinical, radiological and/or histopathological features. Results: A total of 155 patients were enrolled from a total of 4893 admissions done from January 2015 to July 2016. The common presenting symptoms were headache, back pain and paraparesis. Around 26% of patients presented with an altered sensorium, 19.4% with seizures and 21% had at least one cranial nerve involvement. The most common site of involvement was the brain noted in 49.7% of patients. Primary malignancies constituted 78 cases (50.7%) while secondary malignancies included 77 cases (49.3%). Magnetic resonance imaging (MRI) revealed 92 (59.4%) intra-axial lesions and 59 (38.1%) extra-axial lesions, with five cases having both. The most common diagnoses were intra-cerebral metastases and glioblastoma (intra-axial), and vertebral metastases and meningioma (extra-axial). Histopathological confirmation was obtained in 59 patients (38.1%) with 12 primary and 47 secondary lesions. Ten (6.45%) patients had an unknown primary with secondary metastases. The three most common histopathologically confirmed diagnoses were adenocarcinoma lung, plasma cell dyscrasia and adenocarcinoma prostate. Conclusion: Primary neurological consultations with an unknown primary are common hence a high index of suspicion can prevent an inadvertent delay in the diagnosis and appropriate treatment of a malignant lesion. Developing a neuro-oncology register may help us in gaining more insight into such situations.
Perception, awareness, and practice among patients seeking orthodontic treatment toward maintenance of periodontal health and factors affecting the same among patients visiting dental clinics in Patna

Background: During the orthodontic treatment, maintenance of periodontal health is of utmost importance; hence, this study was conducted to explore the perception and awareness of patients seeking orthodontic treatment toward maintenance of periodontal health and factors affecting the same. Materials and Methods: It was a cross-sectional descriptive questionnaire study conducted among134 patients seeking orthodontic treatment from 16 private clinics in Patna. The study was conducted in the month of June 2019. The city was divided into four directions east, west, north, and south and four clinics were selected from each directions randomly. A close-ended questionnaire was prepared consists of demographic details and questions regarding their perception, awareness, and practice to maintain periodontal health from the start of orthodontic treatment. Results: Majority of study participants {74 (55.22%)} were between the age group of 11 and 15 years. Among all study participants, females {81 (60.45%)} were more than males. It was determined that 112 (83.58%) of patients were using tooth brush and tooth paste/powder for cleaning teeth. There was moderate awareness, negative perception, and fair practice of majority of study participants seeking orthodontic treatment toward maintenance of periodontal health. Awareness of study participants was significantly (P-value ≤ 0.05*) associated with practice. Conclusion: There was moderate awareness, negative perception, and fair practice of majority of study participants seeking orthodontic treatment toward maintenance of periodontal health. Education of study participants was significantly associated with awareness and practice regarding maintenance of periodontal health. There is further need to educate the orthodontic patients toward maintenance of periodontal health.
What Comes First Metacognition or Negative Emotion? A Test of Temporal Precedence

The Self-Regulatory Executive Function model predicts that emotional symptoms and metacognition can causally affect each other. Crucially, for the model metacognition must cause emotion disorder symptoms. Therefore, in time-series data involving repeated measurements, metacognitions should predict subsequent changes in emotion. 265 participants completed a questionnaire battery three times over a 2 month period. Structural equation modeling (SEM) using cross-lagged panel analysis tested the inter-relationships between metacognitive beliefs, anxiety and depression symptoms over time. The cross-lagged structural model was a significantly better fit than the autoregressive model. Metacognitive beliefs were found to predict subsequent symptoms of anxiety while symptoms of anxiety predicted later metacognition over different time courses. The metacognition factor representing uncontrollability and danger of thoughts appeared to be prominent in the effects observed. Metacognitions and depression were also positively related over time to a lesser degree, but in the cross-lagged model these temporal relationships were non-significant. This is likely due to low levels of depression within the sample and low variability over time. The findings for anxiety are consistent with the S-REF model and with experimental and prospective studies supporting metacognitive beliefs as a causal mechanism in psychological distress symptoms.
Sham-Chewing in Sows Is Associated With Decreased Fear Responses in Their Offspring

We hypothesized that sham-chewing expressed by the dam during gestation affects fetus programming. The goal of this study was to assess the effects of maternal sham-chewing on offspring welfare indicators, such as behavior and physiology. Sows that exhibited consistent sham-chewing on at least two of 6 days of observation (N = 7) were compared with sows that had never performed sham-chewing (non-sham-chewing sows; N = 4) during these 6 days. Salivary samples from sows and piglets were collected and cortisol concentrations were analyzed to assess the hypothalamic pituitary adrenal (HPA) axis activity as cortisol is a physiological indicator of welfare. Moreover, placental tissue was collected, right after farrowing, to assess cortisol and cortisone concentration. Piglet behavior and fear tests were performed after weaning (one couple per sow). In the fear tests, data was collected in an open field test to determine the states of fear indicators. Non-sham-chewing sows had lower concentrations of cortisol on days 91 and 92 of gestation in the morning. In addition to this, placental cortisol was higher among sham-chewing sows than non-sham-chewing sows. In the open field test, piglets born from non-sham-chewing sows demonstrated more latency to move in the arena and less activity, indicating more fear. Based on our data, we concluded that the expression of maternal sham-chewing is related to less fear in their offspring. Although stereotypies have been studied, attention has not been devoted to the effects of the prenatal period in considering a fetal reprogramming approach.
Genome-Wide Analysis of Circular RNAs Mediated ceRNA Regulation in Porcine Embryonic Muscle Development

Many circular RNAs (circRNAs) have been discovered in various tissues and cell types in pig. However, the temporal expression pattern of circRNAs during porcine embryonic muscle development remains unclear. Here, we present a panorama view of circRNA expression in embryonic muscle development at 33-, 65-, and 90-days post-coitus (dpc) from Duroc pigs. An unbiased analysis reveals that more than 5,000 circRNAs specifically express in embryonic muscle development. The amount and complexity of circRNA expression is most pronounced in skeletal muscle at day 33 of gestation. Our circRNAs annotation analyses show that “hot-spot” genes produce multiple circRNA isoforms and RNA binding protein (RBPs) may regulate the biogenesis of circRNAs. Furthermore, we observed that host genes of differentially expressed circRNA across porcine muscle development are enriched in skeletal muscle function. A competing endogenous RNA (ceRNA) network analysis of circRNAs reveals that circRNAs regulate muscle gene expression by functioning as miRNA sponges. Finally, our experimental validation demonstrated that circTUT7 regulate the expression of HMG20B in a ceRNA mechanism. Our analyses show that circRNAs are dynamically expressed and interacting with muscle genes through ceRNA manner, suggesting their critical functions in embryonic skeletal muscle development.
