Representación escolar de los espacios rurales: una investigación didáctica mediante métodos mixtos

Los espacios rurales son objeto de representación histórica desde un relato homogéneo que no ha sido cuestionado en la geografía escolar y afecta a las explicaciones que realiza el alumnado de Educación Secundaria y Bachillerato. La teoría de las representaciones sociales y su relación con el espacio subjetivo permiten comprender las concepciones escolares del alumnado de diez centros escolares de la provincia de Valencia (España) acerca de los espacios rurales. Mediante un enfoque dual (estructural y procesual) que se acompaña de técnicas cualitativas y cuantitativas aplicadas al campo de la didáctica de las ciencias sociales se pretende diagnosticar los elementos que forman la cosmovisión que tiene el alumnado, como resultado de una representación social que idealiza estos espacios.
Mirror-Less Unidirectional Radiation in an Asymmetric Single Resonator

We propose a novel approach to realize unidirectional radiation in an asymmetric single resonator without using an external mirror, which is based on mutual coupling between two degenerate resonant modes through the background scattering of the asymmetric resonator. In the proposed approach, only one of the resonant modes experiences optical gain and the other works just as an internal reflector. So, our approach is conceptually to mimic a one-port system by introducing the internal reflector in a two-port system. Due to this intuitive and simple operation concept, the design of such devices is straightforward. We described the operation principle by using the temporal coupled-mode theory, from which a practical design method was derived. An example device of the proposed approach was designed based on guided-mode resonances in a slab waveguide grating and its performance was analyzed with the finite-difference time-domain simulation. A ratio of 4.6 x 104 between the upward and the downward radiations was numerically demonstrated.
Two-step crosslinked liquid-crystalline elastomer with reversible two-way shape memory characteristics

ABSTRACT Liquid-crystalline elastomers (LCEs) possess large and equilibrium reversible anisotropic dimensional change in response to applied stimuli. The deformation behavior demonstrated by current LCE materials under the stimuli are generally determined by their own geometries and the alignment distributions of liquid crystal (LC) units in the LCE matrices. Here we report a LCE whose synthesis was through a two-stage crosslinking coupled with a mechanical reshaping process, where the shape was mechanically reset before the final crosslinking. It demonstrated reversible memory and change between the initial geometries formed during the first crosslinking stage and any reshaped geometries under the stimuli. Its deformation is not influenced by the geometries and the alignment distributions of LC units in the LCE matrix. This characteristic in LCEs holds promise in a wide range of application researches requiring sophisticated functions and smart structures.
Connecting the Brains via Virtual Eyes : Eye-Gaze Directions and Inter-brain Synchrony in VR

Hyperscanning is an emerging method for measuring two or more brains simultaneously. This method allows researchers to simultaneously record neural activity from two or more people. While this method has been extensively implemented over the last five years in the real-world to study inter-brain synchrony, there is little work that has been undertaken in the use of hyperscanning in virtual environments. Preliminary research in the area demonstrates that inter-brain synchrony in virtual environments can be achieved in a manner similar to that seen in the real world. The study described in this paper proposes to further research in the area by studying how non-verbal communication cues in social interactions in virtual environments can affect inter-brain synchrony. In particular, we concentrate on the role eye gaze plays in inter-brain synchrony. The aim of this research is to explore how eye gaze affects inter-brain synchrony between users in a collaborative virtual environment.
Zero-Energy Cool Chamber in Anthracnose Disease Management of Postharvest Capsicum frutescens

Anthracnose caused by Colletotrichum gloeosporioides is one of important diseases causing postharvest losses on chili. This study aimed to determine the effectiveness of the zero energy cool chamber (ZECC) in reducing the severity of anthracnose in Capsicum frutescens L. and extending the shelf life of chilies. The research was started by designing and building ZECC as a storage area for chilies. Chilies with and without fungal inoculation were stored in ZECC and storage chamber at room temperature. C. gloeosporioides experienced a growth inhibition of 40.48% after being stored in ZECC compared to its growth at room temperature. Storage of chilies in ZECC was able to reduce the severity of anthracnose by 56.2% on the 15th day, did not affect vitamin C content and total dissolved solids (TSS) and was able to reduce chilies weight loss during storage. Based on the organovisual test using the visual quality rating method and the Hedonic sensory test, consumers prefer chilies stored in the ZECC. The results showed that storage in ZECC could extend the shelf life of chilies. This storage model does not use electricity or is zero energy so it can be used by small scale farmers. This is the first report on the use of ZECC for the management of anthracnose in postharvest chilies in Indonesia.
Clinical Presentation of Parkinson’s Disease: Experience of using Movement Disorder Society Clinical Diagnostic Criteria for Parkinson’s Disease

Aims: Parkinson’s disease (PD) is a common neurodegenerative disorder. As no definite diagnostic tests are available, diagnosis is done mostly clinically. UK Brain Bank criteria is commonly used globally for that purpose. In this study we used Movement Disorder Society (MDS) Clinical Diagnostic Criteria to diagnose PD and document the clinical presentations. Study design: Descriptive cross-sectional study. Methodology: This study was carried out in the department of neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from May 2018 to April 2019. Total 42 patients (4 clinically established and 38 clinically probable PD) were enrolled as study population according to Movement Disorder Society (MDS) Clinical Diagnostic Criteria - 2015 for PD. Their patterns of clinical presentation were recorded. Results: Among the PD patients, 31 were male and 11 were female. Mean age of all patients was 59.43 ± 11.34 years. The most common presenting feature was tremulous movement (90.5%) followed by slowness of movement (40.5%). Only 9% patients had early onset PD. All patients had history of positive response to dopaminergic therapy with documented resting tremor in 95.2%, and end-of-dose wearing off in 75.6%. Constipation was the commonest (69%) non motor symptom followed by sleep dysfunction (64.3%) & depression (50%). On examination- 100% patients had bradykinesia, 97.6% rest tremor, 95.2% rigidity, 21.4% mild dementia and 4.8% moderate dementia. Also 26.2% patients were found to have postural hypotension. 4 patients had red flag features- urinary retention was found in three patients and one patient suffered from recurrent early fall. Conclusion: MDS Clinical Diagnostic Criteria help in accurate diagnosis of PD and include more clinical features which will help in formulating management plan.
Effects of feeding calcareous marine algae to Holstein cows beginning prepartum on postpartum performance and serum metabolites

Thirty-six multiparous Holstein cows and 12 springing heifers were used in a 9 wk randomized design trial to determine the effect of feeding calcareous marine algae (Acid Buf, Celtic Sea, Ireland) from 3 wk prepartum through 6 wk postpartum on dry matter intake (DMI) , milk yield and composition, and blood and urine metabolites. Within parity, animals were assigned randomly to one of four treatments with a 2 × 2 factorial arrangement. Prepartum diets were supplemented with 0 (CON) or 50 g/d calcareous marine algae (CMA) resulting in a DCAD of -3 and -5 meq/100g, respectively. Postpartum diets were supplemented with either 317 g/d sodium bicarbonate (NBC) or 100 g/d CMA to achieve a DCAD of 35 and 17 meq/100g, respectively. No differences (P = 0.6142) were observed in prepartum DMI which averaged 11.9 and 12.2 kg/d for CON and CMA, respectively. Postpartum DMI, milk yield, percentage of milk fat, protein, lactose, and SNF were not different (P > 0.10) among treatments and averaged 18.0, 38.1, 4.02, 2.71, 4.75, and 8.37; 19.8, 39.0, 3.96, 2.85, 4.74, and 8.38; 19.4, 37.3, 4.01, 2.71, 4.75, and 8.41; and 20.0 kg/d, 38.1 kg/d, 4.24%, 2.81%, 4.72%, and 8.37% for CON-NBC, CMA-NBC, CON-CMA, and CMA-CMA, respectively. Milk protein yield was higher (P = 0.0453) for cows fed CMA prepartum compared with CON; 1.09 and 1.02 kg/d, respectively. Interactions of prepartum treatment and wk were observed for yield of milk fat (P = 0.0222), energy-corrected milk (ECM, P = 0.0395) and 3.5% fat-corrected milk (FCM, P = 0.0290) because of higher yields for cows fed CMA during wk 2 and 6 compared with CON. An interaction of prepartum treatment and wk (P < 0.05) was also observed for milk efficiency (ECM/DMI, FCM/DMI) because of lower efficiencies for cows fed CMA during wk 1 and 4 compared with CON; however, efficiencies tended to reverse and were numerically higher for CMA compared with CON during wk 6. Serum Na concentrations were greater (P < 0.05) for cows fed CON prepartum or NBC postpartum compared with CMA. Postpartum urinary concentrations of Na exhibited an interaction among treatments (P = 0.0353) and were higher for CON-NBC and CMA-NBC compared with CON-CMA and CMA-CMA; 121.21, 105.43, 41.24 and 59.55 mmol/L, respectively. Similar interactions of treatments (P < 0.05) were also observed for serum urea N and creatinine postpartum. Postpartum urinary K concentrations were higher (P = 0.003) for cows fed CMA postpartum compared with NBC; 155.60 and 118.40 mmol/L, respectively. Results of this trial indicate that cows feeding CMA prepartum does not affect DMI or serum metabolites prepartum, but supported higher milk protein yields and increases in ECM and FCM postpartum. Efficiency of milk production was higher for CON during wk 1 and 4, but was not different afterwards. Performance and serum metabolite concentrations of cows fed CMA postpartum were comparable with that of cows fed NBC except for changes in serum and urinary concentration of Na related to dietary intake of Na.
Investigating Residents’ Attitudes towards Tourism Growth in Downtown Greenville, SC: The Effect of Demographic Variables

Given the high density of urban spaces, residents and tourists share resources and infrastructure in limited spaces. The purpose of the study is to investigate the influence of residents’ perceived tourism impacts on their attitudes towards tourism growth, the effect of proximity to tourism center on residents’ attitudes, and how this effect is moderated by residents’ demographic features (age, gender, length of residence) in urban settings. A total of 251 responses were collected in downtown Greenville, a tourist zone located in the heart of Greenville, SC, USA. Using multiple regression models and ANOVA, the study suggested that (1) economic impact was the most important predictor of residents’ attitudes towards tourism growth, (2) downtown residents were more favorable of tourism growth than county residents, and (3) Age and gender moderated the effect of proximity to a tourism center on residents’ attitudes towards tourism growth.
The Generative Mechanism of Boomerang Intention: From the Perspective of Legacy Identification

Boomerang employment has become an increasingly significant third way to obtain employees, yet little research has focused on why does ex-employee want to come back. Drawing from social identity theory, we propose that legacy identification could increase boomerang intention and both perceived corporate prestige and psychological contract violation could affect boomerang intention through legacy identification. The cooperative relationship between the former organization and the current organization could enhance these effects. Results from a two-time points survey of 202 Chinese employees showed that legacy identification could increase boomerang intention, perceived corporate prestige could increase boomerang intention via legacy identification, psychological contract violation could decrease boomerang intention via legacy identification. Besides, the positive effect of legacy identification on boomerang intention, the positive indirect effect of corporate prestige on boomerang intention via legacy identification, and the negative indirect effect of psychological contract violation on boomerang intention via legacy identification are all stronger when there is a cooperative relationship. Theoretical and practical implications are discussed.
Self-Folding Polymer Iron Catalysts for Living Radical Polymerization

Iron-bearing self-folding polymers were created with amphiphilic random copolymers as active, versatile, and recyclable polymer-supported catalysts for living radical polymerization (LRP). The key is to build bis(imino)pyridine ligand cavities for iron complexes as linking units within self-folding polymers. Self-folding polymer ligands are synthesized by the intramolecular imine cross-linking of self-folded amphiphilic random copolymers bearing hydrophilic poly(ethylene glycol) (PEG), hydrophobic dodecyl, and urea/aniline pendants with 2,6-pyridinedicarboxaldehyde in water. The folding polymers efficiently formed iron complex catalysts in the cores to induce LRP and random or block copolymerization of various methacrylates. The self-folding polymer catalysts not only showed high activity and tolerance to functional groups such as acid, hydroxyl groups, and oxygen but also afforded easy product recovery and catalyst recycle thanks to hydrophilic PEG chains.
Neoliberalism and the Ideological Construction of Equity Beliefs

Researchers across disciplines, including psychology, have sought to understand how people evaluate the fairness of resource distributions. Equity, defined as proportionality of rewards to merit, has dominated the conceptualization of distributive justice in psychology; some scholars have cast it as the primary basis on which distributive decisions are made. The present article acts as a corrective to this disproportionate emphasis on equity. Drawing on findings from different subfields, we argue that people possess a range of beliefs about how valued resources should be allocated—beliefs that vary systematically across developmental stages, relationship types, and societies. By reinvigorating notions of distributive justice put forth by the field’s pioneers, we further argue that prescriptive beliefs concerning resource allocation are ideological formations embedded in socioeconomic and historical contexts. Fairness beliefs at the micro level are thus shaped by those beliefs’ macro-level instantiations. In a novel investigation of this process, we consider neoliberalism, the globally dominant socioeconomic model of the past 40 years. Using data from more than 160 countries, we uncover evidence that neoliberal economic structures shape equity-based distributive beliefs at the individual level. We conclude by advocating an integrative approach to the study of distributive justice that bridges micro- and macro-level analyses.

Automotive OEM Demand Forecasting: A Comparative Study of Forecasting Algorithms and Strategies

Demand forecasting is a crucial component of demand management, directly impacting manufacturing companies’ planning, revenues, and actors through the supply chain. We evaluate 21 baseline, statistical, and machine learning algorithms to forecast smooth and erratic demand on a real-world use case scenario. The products’ data were obtained from a European original equipment manufacturer targeting the global automotive industry market. Our research shows that global machine learning models achieve superior performance than local models. We show that forecast errors from global models can be constrained by pooling product data based on the past demand magnitude. We also propose a set of metrics and criteria for a comprehensive understanding of demand forecasting models’ performance.
The relationship between resilience and organisational control systems in the South African aviation industry

Background: Organisational control systems, such as quality assurance and corporate governance, configure an organisation’s internal environment to manage the velocity of change and pro-actively stabilise disturbances. Resilience in a socio-technical system is a multi-disciplinary approach to instil a system’s transformability and adaptive capacity to achieve desirable outcomes and continuous improvement. This study confirms theoretical postulations that detachment between the disciplines of quality assurance and corporate governance reduces resilience in a socio-technical system. Coherence between these disciplines in a complex socio-technical system is achieved through four components of organisational resilience: strategic management and company culture, monitoring and awareness, exposure management and responsive adaptation. Objectives: This study aimed to explore stakeholders’ perceptions of the relationship between the components of organisational resilience and organisational control systems in the South African aviation industry. Method: A cross-sectional survey was used to collect data from 203 stakeholders in the South African aviation industry. The data set was subjected to descriptive and inferential statistical analyses. Results: A strong positive linear relationship exists between organisational control systems and organisational resilience and its four components: Strategic management and company culture, Monitoring and awareness, Exposure management and Responsive adaptation. Conclusion: This study revealed that a harmonised application of organisational control systems, such as quality assurance and corporate governance, stimulates organisational resilience in a socio-technical system through the autonomous advancement of four components of organisational resilience. Furthermore, the robustness of organisational control systems activates an organisation’s capacity to adapt sustainably, whilst maintaining stakeholder value within complex socio-technical systems, such as the aviation industry.
Effect of Cooking Conditions on the Flavor Formation and Adulteration Detection by Cluster Analysis of the Traditional Chinese Chicken Soup

Traditional Chinese chicken soup (chicken soup in pottery pot) is made of Chinese native chicken with ginger, green onion, black pepper and rice wine and stewed for several hours, which is famous for its delicate processing and flavor [1]. However, due to economical motivations, many restaurants in Asian countries claim their chicken soups are made in traditional cuisine, actually they use the low cost canned pressure chicken soups instead.
Predation capacity of soil-dwelling predatory mites on two major maize pests

The western corn rootworm Diabrotica virgifera virgifera (WCR), and the wireworm Agriotes sordidus (WW), whose eggs and first instar larvae develop in the first few centimeters of soil, are major crop pests. As soil-dwelling predatory mites are known as potential biocontrol agents against many pests, we investigated the predation capacity of Stratiolaelaps scimitus, Gaeolaelaps aculeifer and Macrocheles robustulus on immature stages of WCR and WW in a laboratory setting. While eggs of WCR and WW were never consumed, all three predator species attacked both WCR and WW first instar larvae. While these results need to be confirmed in natural conditions, our work identifies the early larval stage instead of the egg stage as the most vulnerable stage for control against WCR and WW with soil-dwelling predatory mites.
New Insights Into Potassic Intraplate Volcanism in Northeast China From Joint Tomography of Ambient Noise and Teleseismic Surface Waves

Wudalianchi volcano is one of the youngest volcanic groups among the Cenozoic intraplate volcanoes in Northeast China and is notable for its potassium‐rich basalts. With newly deployed dense broadband seismic stations, we construct a high‐resolution 3‐D S‐wave velocity model of Wudalianchi volcano and its adjacent region, including the Keluo and Erkeshan volcanoes, using ambient noise and teleseismic surface wave tomography. We find a prominent channel‐like low‐velocity body that extends from the Moho to a depth of 100 km directly beneath the Wudalianchi, Erkeshan, and Keluo (WEK) volcanoes. This low‐velocity anomaly suggests that these three volcanoes may be derived from the same mantle magmatic source. Our model also shows that the prominent low‐velocity anomaly is associated with the pervasive low‐velocity anomalies at a depth of 100–200 km, which is interpreted as the asthenosphere. We further find that the lithosphere beneath the WEK volcanoes thickens abruptly from ∼80 to ∼110 km. Combining our results with those of other geophysical studies, we propose a geodynamic scenario for WEK intraplate volcanism. When the background asthenospheric flow in Northeast China encounters sharp changes in lithosphere thickness beneath the WEK volcanoes, it produces locally turbulent flow, promotes asthenospheric upwelling, and finally forms volcanoes.
Detecting Sub‐Micron Space Weathering Effects in Lunar Grains With Synchrotron Infrared Nanospectroscopy

Space weathering processes induce changes to the physical, chemical, and optical properties of space‐exposed soil grains. For the Moon, space weathering causes reddening, darkening, and diminished contrast in reflectance spectra over visible and near‐infrared wavelengths. The physical and chemical changes responsible for these optical effects occur on scales below the diffraction limit of traditional far‐field spectroscopic techniques. Recently developed super‐resolution spectroscopic techniques provide an opportunity to understand better the optical effects of space weathering on the sub‐micrometer length scale. This paper uses synchrotron infrared nanospectroscopy to examine depth‐profile samples from two mature lunar soils in the mid‐infrared, 1,500 –700 cm−1 (6.7–14.3 μm). Our findings are broadly consistent with prior bulk observations and theoretical models of space weathered spectra of lunar materials. These results provide a direct spatial link between the physical/chemical changes in space‐exposed grain surfaces and spectral changes of space weathered bodies.
