Ecotourism and Malaysia’s Orang Asli: the social construction of indigeneity in community boundary-drawing

ABSTRACT This qualitative study conducted in Malaysia’s Belum-Temengor Forest Reserve applies the concept of indigeneity as a social construct to examine status ascription by two competing groups: the Orang Asli and the Malays. Through indigeneity, the Orang Asli assert themselves as the rightful inhabitants of Belum-Temengor and brand the Malays as outsiders. By contrast, the Malays downplay indigeneity and describe themselves as ‘the locals’ whose entrepreneurism should be lauded. Tourism in Belum-Temengor influences the discourse of indigeneity in two paradoxical ways – it reinforces the Orang Asli’s indigeneity by accentuating the indigenous culture in tourism products; but it also exerts the pressure of assimilation as a pre-condition of participation. The theoretical implication lies in demonstrating that the interplay of indigeneity influences the socio-psychological boundary of a community, such that a group that sees itself as part of a community is considered by the competing group to be the outsider.
H∞ deconvolution filter for two‐dimensional numerical systems using orthogonal moments

In this article, we propose the issue of H∞ deconvolution filtering for two‐dimensional (2D) systems described by the Fornasini–Marchesini local state‐space model. The main challenge is the design of a deconvolution filter to rebuild the 2D signal so that the filter error system is asymptotically stable and preserves a guaranteed H∞ performance. To overcome this issue, we use some free matrix variables to eliminate coupling between Lyapunov matrix and system matrices to obtain sufficient conditions in linear matrix inequality form to ensure the desired stability and performance of the error systems in the first time. Moreover, we use the orthogonal moments to extract the feature vectors to generate the input system, with the minimum information with and without noise. Simulation examples are provided to show that the new design technology proposed in this article achieves better H∞ performance than the existing design methods. Finally, this work can be very helpful tools for the practitioners in telecommunication, and data scientists to aid them in deconvolution, diagnostic, and transmission.
Meteorological Navigation by Integrating Metocean Forecast Data and Ship Performance Models into an ECDIS-like e-Navigation Prototype Interface

In the complex processes of route planning, voyage monitoring, and post-voyage analysis, a key element is the capability of merging metocean forecast data with the available knowledge of ship responses in the encountered environmental conditions. In this context, a prototype system has been implemented capable of integrating metocean models forecasts with ship specific performance data and models. The work is based on the exploitation of an open source ECDIS-like system originally developed in the e-Navigation framework. The resulting prototype system allows the uploading and visualization of metocean data, the consequent computation of fuel consumption along each analyzed route, and the evaluation of the encountered meteo-marine conditions on each route way point. This allows us to “effectively and deeply dig inside” the various layers of available metocean forecast data regarding atmospheric and marine conditions and evaluating their effects on ship performance indicators. The system could also be used to trigger route optimization algorithms and subsequently evaluate the results. All these functionalities are tailored in order to facilitate the “what-if” analysis in the route selection process performed by deck officers. Many of the added functionalities can be utilized also in a shore-based fleet monitoring and management center. A description is given of the modeling and visualization approaches that have been implemented. Their potentialities are illustrated through the discussion of some examples in Mediterranean navigation.
Internationalization of social work education in India through student exchanges: challenges and prospects

ABSTRACT Internationalization of social work education in terms of student mobility, staff mobility, curriculum transaction and research collaboration are getting on priority agendas of universities across the globe. This could be attributed to the demands of the profession to be cultural sensitive and being adaptive to the educational standards which could empower the practice. Indian social work education and its internationalization is discussed in this paper in the context of ‘International student exchanges’ from author’s experience. This paper is descriptive and based on a single case study of one school of social work in South India. Social work interns who participated in international exchanges appreciate the need for knowledge of global priorities and strategies to advance social work education, research and skill development for practice. Though the literature focus more on different models of international student mobility programs, there need to have deliberations, rules of partnership and clear exchange goals specifically on ‘international student exchanges’, which will contribute towards the internationalization of Indian social work education. This paper identify the importance of International student exchanges in internationalizing Indian social work education as well as opening new avenues of collaboration.
Thalamic Deep Brain Stimulation Is Effective in Alleviating Craniocervical Dystonia

Meige syndrome (MS) is an idiopathic adult-onset segmental dystonia characterized initially by blepharospasm, followed by dystonia of the mid-facial and lower facial muscles, mouth, jaw, tongue, or pharyngeal muscles. Patients with MS may have further spread of dystonia to the cervical muscles, leading to craniocervical dystonia (CD). Severe Meige or CD is often refractory to oral medications. Botulinum toxin (BTX) injections remain the cornerstone of the management of MS or CD, although many patients experience a diminished response over time attributed to either progression of the disease or development of neutralizing antibodies. We and other groups have reported the effectiveness of deep brain stimulation (DBS) of either the globus pallidus internus or subthalamic nucleus for medically refractory MS or CD. We report on a patient with medically refractory CD who underwent bilateral asleep DBS surgery of the ventralis intermedius nucleus (VIM) with dramatic response.
The clinical value of 18F-fluoroestradiol in assisting individualized treatment decision in dual primary malignancies.

Background For patients with previously diagnosed dual primary tumors, it is usually difficult to determine the diagnosis and treatment of stage IV recurrence. The study was to explore the influences of 18F-fluoroestradiol positron emission tomography/computed tomography (18F-FES PET/CT) in the diagnosis of estrogen receptor (ER) positive breast cancer combined with other primary tumor with distant metastases. Methods Multidisciplinary team were organized to explore the definite clinical value of 18F-FES PET/CT in stage IV patients suffered from ER-positive breast cancer and another primary tumor synchronously or metachronously. Thirty-two female patients were retrospectively analyzed who underwent 18F-FES PET/CT scans in our center. Before and after reading 18F-FES reports, the team members from department of surgery, oncology and radiotherapy should make decisions of management strategy. Results Totally, the multidisciplinary team completed the management decision-making of the 32 patients before and after 18F-FES PET/CT scans. 87.5% (n=28) of the patients were considered to benefit from 18F-FES reports for diagnosis and treatment decisions. Out of the 28 patients, 7 patients (7/32, 21.9%) were considered to definitely change the management strategies while 12 patients (12/32, 37.5%) was instructive to develop management plans after the scan. The other 9 patients were suggested reassuring decision-making process by 18F-FES PET/CT. Conclusions 18F-FES PET/CT scans have clinical effects on diagnosis and treatment strategies of stage IV patients suffered from ER-positive breast cancer and another primary tumor.
Effects of Long Upward Connecting Leader Channel on Electromagnetic Fields for Lightning Striking to Tall Towers

The effects of long upward connecting leader (UCL) channel on electromagnetic fields for lightning striking to tall towers are studied via lightning transmission-line return-stroke model. The current distributions along the lightning channel and the tower are derived, and the resultant lightning electromagnetic fields with various UCL lengths above tower are calculated at close and far distances. It can be found that the contribution of the various components of the electric and magnetic fields depends strongly on the distance to the observation point. Electric field has a shading effect showing that the field amplitude generated by lightning striking to tall towers is smaller than that to ground, and that this shading effect depends on the UCL length and the tower height. However, we cannot find such an effect for the magnetic field. The shading effect of the electric field increases with the increase of the junction height above tower, but disappears when the observation distance exceeds a critical distance. Modeled results are also compared with their measured counterparts associated with lightning striking to the 600 m tall Canton Tower. The proposed model can explain why the ratios of peaks of luminosity to magnetic field of the downward first stroke are considerably larger than those of the subsequent strokes as being due to the fact that the junction height above tower for first stroke is higher than that for subsequent stroke, whereas the downward return stroke speed of first stroke is smaller than that of subsequent stroke.
El debate electoral del 10-N de 2019 en España: los candidatos políticos y RTVE

Electoral campaigns aim to increase participation to capture the votes of the electorate. In this sense, the privileged space to approach the citizens is the debate, which in Spain exceeds a million viewers. Although, the conventional media are decisive in campaigns. Television is still the main media outlet chosen by the Spanish citizens, according to the ‘Center for Sociological Research’, to follow political information of the electoral campaign. The objective of this research is to analyze the speeches of political candidates in the 10-N election debate in Spain. On the other hand, we seek to conclude whether the discourses of Spanish Radio and Television (RTVE) about the debate on Twitter are a reproduction of political discourse or whether the function of public service media is fulfilled. For the analysis of the political discourse and electoral debate in RTVE, we use framing theory as an analysis methodology. The findings of this study show that public television informed citizens without reproducing political discourse, although tweets dedicated to conflict between candidates and the presentation of PSOE measures were the most frequent.
Hierarchical Microspheres Based on α-Ni(OH)2 Nanosheets Intercalated with Different Anions: Synthesis, Anion Exchange, and Effect of Intercalated Anions on Electrochemical Capacitance

Hierarchical microspheres composed of wrinkled α-Ni(OH)2 nanosheets were synthesized from an aqueous solution containing nickel salts, hexamethylenetetramine, 1-butanol, and dodecyl sulfate. The exchange of intercalated dodecyl sulfate anions within the microspheres by smaller anions (Cl–, NO3–, OAc–, and SO42–) resulted in retention of morphology. A possible growth mechanism is proposed based on the observation of the effects the parameter variation (different nickel and hydroxide sources, several alcohols, with and without dodecyl sulfate as well as 1-butanol) had on microsphere formation. Electrochemical and capacitive properties of the anion-exchanged microspheres were studied by cyclic voltammetry and galvanostatic charging–discharging. Interestingly, the specific capacitance was determined by size of the intercalated anions and not by the basal spacing; for example, the largest anion, SO42–, gave the lowest specific capacitance, whereas the smallest anion, Cl–, gave the highest specific capacitance.
Imaging of Ampullary and Periampullary Conditions

Abstract The ampulla of Vater is formed by the union of the pancreatic duct and the common bile duct and is also known as hepatopancreatic ampulla or hepatopancreatic duct. The ampulla is surrounded by a muscular valve known as the sphincter of Oddi, which controls the flow of bile and pancreatic juices into the duodenum in response to food. The ampulla is also an important embryological landmark as it marks the anatomical transition from foregut to the midgut. Because of this, it is a watershed zone where the blood supply changes from the celiac axis to the superior mesenteric artery. Radiologic evaluation of the ampulla and the periampullary region is challenging because it requires an understanding of the embryology, the normal appearance, and different anatomic variants. Also, a wide variety of pathologies can occur in this region. The purpose of this review is to present the normal anatomy of the ampulla and the periampullary region on different imaging modalities and to summarize the imaging features of the common variants, and benign and malignant ampullary and periampullary conditions. Understanding of the normal anatomical appearance and variants along with the knowledge of common pathologic conditions affecting the ampulla and periampullary conditions can help radiologists in making accurate diagnosis resulting in optimum patient care.
An epidemiological study of the prevalence and determinants of overweight and obesity in women of reproductive age (15 to 49 years) group in an urban slum

Background: After comparing data of NFHS-3 and 4, prevalence of overweight and obesity in women of an urban population almost doubled in 10 yr. So, the causes of increasing prevalence need to be studied as public health concern. Objective of the study is to determine prevalence of overweight and obesity among reproductive age group (15-49 years) of women in an urban slum of Mumbai.Methods: Total 220 women were selected among 11 sectors from A to K by simple random method and data collected by using validated questionnaire. WHO’s classification was used to classify as overweight and obese.Results: Out of 220 women participated in study, 14 (6.36%) were obese, 75 (34.09%) were overweight according to BMI and 17 (7.7%) were found to be obese according to waist to hip ratio. From the present study it was seen that age group of the women, socio economic class, education, history of hypothyroidism, family history of obesity, types of work women do, hours of television watching, calorie and fat intake, had a significant relationship with BMI, whereas physical exercise they used to do and tendency to sleep in the afternoon and hours of sleep in the night had non-significant relationship with BMI.Conclusions: Obesity and overweight is found to be a growing public health problem and can be preventable. Interventional measures include developing healthy eating habits, regular moderate physical exercise, sleeping habits, health camps for screening of overweight and obesity.
Capturing CO2 with Amine-Impregnated Titanium Oxides

A series of porous titanium oxides was synthesized using different alkylamines and modified by amines, including diethylenetriamine (DETA), triethylenetetramine (TETA), and tetraethylenepentamine (TEPA), for CO2 capture. These new composite CO2 sorbents were characterized by powder X-ray diffraction, transmission electron microscopy, nitrogen adsorption, Fourier transform infrared spectroscopy, and thermogravimetric analysis. Their CO2 capture performances were evaluated in a fixed-bed reactor equipped with online mass spectroscopy. Experimental results revealed that CO2 uptake capacities of the titania composite sorbents increase with amine loading but decrease with the size of impregnated amines. The highest CO2 sorption capacity achieved with the sorbents is 2.64 mmol/g. It is also found that, besides the surface area and pore volume, the pore size of the support also plays an important role in determining the CO2 uptake capacity of the composite sorbents. In addition to their high CO2 adsorption capac.
Central Governments in Multi-level Governance Systems Facing the Challenge of Jurisdictions with Rising Emissions

Policy makers in federated countries and the EU seeking to reduce total greenhouse gas emissions face a challenge when emissions are rising in some subnational jurisdictions. The magnitude of that challenge is influenced by the portion of total emissions represented by those jurisdictions, the rate of change in that portion, and the political power of those jurisdictions. This phenomenon is examined by a comparison of the role of rising-emission jurisdictions in the EU and Canada. We define a “rising-emission jurisdiction” as one in which emissions were higher in 2018 than in 1990, regardless of how its emissions may have risen or fallen between those dates. Those findings show that the role of rising-emission jurisdictions must be added to the factors identified in the literature explaining why between 1990 and 2018 EU emissions have declined by 25% while Canadian emissions have increased by 21%. To better understand this phenomenon and to help policy makers cope with it, more research is needed on its influence in other federated countries.
Enhanced Efficiency and Stability in P3HT:PCBM Bulk Heterojunction Solar Cell by using TiO2 Hole Blocking Layer

Insertion of TiO 2 layer between Al negative electrode and active layer of bulk-heterojunction gave a high solar conversion efficiency and high stability. The TiO 2 layer was prepared by spin-coating titanium(IV)isopropoxide (Ti(OC 3 H 7 ) 4 ) on active layer of blended P3HT:PCBM. The parallel resistance (Rp) is increased by inserting TiO 2 layer leading to an increase in Voc. The TiO 2 layer works as a hole blocking layer and prevents the physical and chemical damages by the direct contact between P3HT:PCBM active layer and Al electrode resulting in improvement of the parallel resistance and rectification. The efficiency of P3HT:PCBM bulk heterojunction cell with TiO 2 hole blocking layer attained 4.05% with a Isc 9.72 mA/cm 2 , Voc 0.60 V, and FF 0.70 by using optimized TiO 2 film thickness and ratio of P3HT:PCBM condition.
The structural roots of food insecurity: How racism is a fundamental cause of food insecurity

Rates of food insecurity skyrocketed during the COVID-19 pandemic, doubling overall and tripling among households with children Even before the pandemic, the rate of food insecurity in the United States was “unusually high” compared to other rich democracies, and rates have not improved substantially over the last 25 years What explains the lack of progress in addressing food insecurity? This article maps out an overview of the experiences, causes, and consequences of food insecurity in the United States We demonstrate that racism is a fundamental cause of food insecurity, both because racism contributes to racial disparities in income and wealth, and because racism is linked to food insecurity independent of poverty and socioeconomic status For example, people of color are more likely to experience racial discrimination, which is associated with food insecurity, and to live in states where stricter regulations and harsher punishments are tied to social assistance programs, including food assistance programs Because racism is a fundamental cause of food insecurity, eliminating it requires going beyond “just” eliminating poverty Instead, the fundamental cause must be tackled directly: racism itself, which is built into the structure of American society and entrenched in its institutions © 2021 John Wiley & Sons Ltd
Underestimated MJO Variability in CMIP6 Models

The Madden‐Julian Oscillation (MJO) is the leading mode of intraseasonal climate variability, having profound impacts on a wide range of weather and climate phenomena. Here, we use a wavelet‐based spectral Principal Component Analysis (wsPCA) to evaluate the skill of 20 state‐of‐the‐art CMIP6 models in capturing the magnitude and dynamics of the MJO. By construction, wsPCA has the ability to focus on desired frequencies and capture each propagative physical mode with one principal component (PC). We show that the MJO contribution to the total intraseasonal climate variability is substantially underestimated in most CMIP6 models. The joint distribution of the modulus and angular frequency of the wavelet PC series associated with MJO is used to rank models relatively to the observations through the Wasserstein distance. Using Hovmöller phase‐longitude diagrams, we also show that precipitation variability associated with MJO is underestimated in most CMIP6 models for the Amazonia, Southwest Africa, and Maritime Continent.
Population exposure to compound dry and hot events in China under 1.5 and 2°C global warming

Both droughts and hot extremes may exert critical impacts on human society, and their concurrence is no exception. Global warming is expected to increase the frequency and intensity of compound dry and hot events widely, the impacts of which will be particularly severe for sensitive and vulnerable sectors. However, projected risk and impact of compound dry and hot events in China are less assessed, especially in the context of the goals specified by the Paris Agreement in 2015. Here, we show an overall increased risk of compound dry and hot events on human health in China, particularly in eastern regions, for the two warming levels (1.5 and 2°C) based on Coupled Model Intercomparison Project Phase 5 climate models. The population exposure to extreme compound dry and hot events is projected to increase by about 165.46% for the 1.5°C warming and about 200.49% for the 2°C warming compared with the exposure in the present period 1986–2005. These potential variations are driven by climate change and population change with climate effect being the dominantly positive contributor. These findings highlight the urgent need for more efforts to limit warming within 1.5°C to reduce the risk of compound dry and hot events and associated impacts on human society.
Pulse Electric Field Technology for Wastewater and Biomass Residues’ Improved Valorization

Development and adoption of more efficient and robust technologies for reuse of wastewater embedded resources, in particular materials and energy, is becoming an unavoidable necessity. Among many emerging technologies in the sector of wastewater treatment residuals valorization, Pulsed Electric Field (PEF) processes have shown interesting potential, although they have not yet entered the sector’s mainstream as a consolidated commercial technology, as in other industrial applications, such as the food, medical, and bio-based industries. PEF is a non-thermal technology suitable to biological applications, involving gentle cell disintegration and enhanced cell membrane permeability and as such applicable to disinfection, sterilization, and to those processes that benefit from an enhanced extraction of organic compounds from biological matter, such as anaerobic digestion, biological processes for recovery of nutrients, and biorefinery of cell-embedded compounds. PEF technology applications in wastewater/biomass residues management are reported and advantages, drawbacks, and barriers of the technology are discussed in this paper.
