Sephardi Balads
Authors: Pomeroy Hilary
Published: September 2019

Spanish ballads, narrative poems brought to Morocco following the Expulsion from Spain, became one of the most popular forms of entertainment in the cities where the Spanish Jews settled. However, entertainment was not the only purpose of these highly dramatic songs. They often imparted a moral sentiment, with adultery, for example, invariably punished. Although ballads appear to be exclusively a woman’s genre, sung in the home and handed down to the daughters who kept this oral tradition alive, all members of the family would have known them as they became an essential part of daily life, being sung as lullabies and during different stages of the life cycle. True to the Spanish ballads’ original purpose of disseminating news, Sephardi Moroccan creations narrate dramatic events in Morocco and closely resemble the early Hispanic poems from which they derive.
Prelude to Colonialism
Authors: Laskier Michael M.
Published: September 2019

This study is a portrayal of Moroccan Muslims and Jews by European travellers, journalists, experts and diplomats from the latter half of the nineteenth century until the transformation of Morocco in 1912 into a colonial entity under French and Spanish protectorates. In this pre-colonial setting, we catch a glimpse of a traditional society and its gradual, albeit partial, evolution towards modernity among the Jews as well as an understanding of Europe’s economic, political and cultural penetration into the Sharifian Empire, which for hundreds of years preserved its independence when many Islamic societies capitulated to foreign domination. What were the major challenges confronted by Morocco in the pre-colonial era? Did Muslims and Jews conform to or reject modernisation brought by European culture? What were the socioeconomic conditions and the juridical status of the Jews vis-à-vis the Muslim majority? These are some of the main concerns of our investigation.
The emergence of the global debt society
Authors: Vaccaro Ismael , Hirsch Eric , Sabaté Irene
Published: September 2019

As a result of the financialization of household and national economies, indebtedness has become a system of domination shaping the making of contemporary subjects. This sort of governmentality through debt is a multifaceted phenomenon affecting people's economic and political behavior in both the North and the South. Disguised and legitimized by the moral obligation to repay debts, and by promises of upward social mobility (for the working classes in the North) and of development (for the population of the Global South), indebtedness disciplines households and neutralizes political agency under finance capitalism, as our ethnographic examples on the mortgage crisis in Spain and on microfinance in Peru reveal.
Morphological diversity of channel patterns of braided rivers
Authors: Chalov R. S.
Published: September 2019

The paper presents the description of main channel types of braided rivers distinguished in the channel pattern classification produced in the Moscow State University. It is shown that the diversity of braided channels is determined by various conditions of their formation, different degree of channel stability and other factors. This diversity is defined by the number, size and shape of islands, formation of islands in channel arms, composing bifurcations of the 2nd and 3rd orders, presence of floodplain branches (floodplain multi-channel), symmetry or asymmetry of braided reaches themselves, development of the bends of the branches, water discharge of the branches and distribution of runoff over them in different phases of water regime, high- and low-water years, etc. Also braided channel reaches occur when cut-off meanders are formed (incomplete meandering). On the largest rivers there are braided reaches which are characterized by the development of branches in different parts of the river valley bottom and differing in their channel and even water regime. Certain features are typical for braided reaches of wide-floodplain or incised channels, for rivers with a one-sided floodplain. As a result single, conjugated, floodplain, parallel branches, one-sided, alternate one-sided braided reaches can be either simple (for example, single or parts of conjugated formed by one island) or complex, and the latter are represented by several varieties. The identification of various morphological types, subtypes and varieties of braided channel reaches is directly connected and determines the methods of channel processes management in water economy and water transport development of rivers, construction of communications through rivers, etc.

Published: September 2019

GA R01‐40‐08 (Reg. no. GP‐1060, PI 690433), is a Gossypium hirsutum L. germplasm line developed by the Molecular Cotton Breeding Laboratory, Department of Crop and Soil Sciences, at the University of Georgia. GA R01‐40‐08 was selected from an interspecific backcross inbred population derived from the cross of ‘Tamcot 2111’ (G. hirsutum) with ‘Pima S‐6’ (G. barbadense L.). This G. hirsutum germplasm line harbors an introgressed quantitative trait locus (QTL), qFL‐Chr.1, conferring improved upper half mean fiber length (UHML) from Pima S‐6. Field trials conducted in Plains and Tifton, GA, in 2009, 2013, and 2014 indicate that GA R01‐40‐08 exhibits improved UHML of 1.5 mm longer than the Tamcot 2111 parent, representing a 5% improvement. GA R01‐40‐08 had fiber yields over 18% higher than the Pima S‐6 parent and equivalent to the higher‐yielding parent, Tamcot 2111. This germplasm line represents a milestone in upland cotton germplasm improvement as the first publicly released germplasm line carrying a fiber length QTL with an effect that has been validated in multiple environments. It will provide upland cotton breeders with an adapted source of the qFL‐Chr.1 QTL for improved UHML from G. barbadense, and the tightly linked markers published previously will allow breeders to use marker‐assisted selection for rapid incorporation.

Authors: Jonga Modou
Published: September 2019

This paper attempt to explore the documented challenges that constrain human resource development (HRD) under decentralization process in Local Government Authorities (LGAs) in The Gambia. Critical review on the demands of decentralization and human Resources Capacity gap was thoroughly done to set the basis for the paper. The Paper used documentary sources to gather information relevant to the thematic area. These included journal articles, books, Government Reports and Local Government Service Regulations. Observation method was also used based on the author’s background and experience in the thematic area. The paper found that decentralization as a process and as an approach has limited potential that enhance development of Human Resource Capacity in the Local Government Authorities in The Gambia. However the paper noted three major challenges which are multi-faceted and integrated in character. They comprise policy induced challenges, skills and Organization challenges and performance induced challenges. Hence the paper strongly recommends on institutional review and re-design the institutionalization of HRD, conduct a robust capacity assessment in all the Local Councils to measure their capacity and readiness to meet the demands of the decentralizationprocess. Enforcement mechanisms with financial support, change of mind set and working culture and finally political and leadership will remain critical for bridging the existing Human Resource capacity gaps to meet the demands of decentralization within the Local Government sector.

Authors: Heryati Mr , Rachmawati Murni , Faqih Muhammad
Published: September 2019

The explanation of symbolic meaning would differ from one cultural group to another. In the view of Tondano Javanese people, the symbolic meaning has a very close meaning in the construction of the houses they are living in, start from the stage of preparation/pre-construction to post-construction. This is something that motivates the conduction of special study about the relation of the symbolic meaning of Minahasanese traditional house within the cultural context of Tondano Javanese society. The method of this research was a case study where the data collection was carried out in triangulation and the analysis was carried out descriptively. The meaning interpretation referred to Sassure and Barthes. Result of the study shows that the construction process which starts from the preparation process up to post-construction contains symbolic meaning marked by physical and non-physical forms. Its denotative meaning is more of the consideration of power/strength shown in joints and the placement of pillars and beams. Its connotative meaning is more on the expectation for prosperity, happiness, and safety both in the world and the after-life which is symbolized by the norms of building, while the myth refers to a belief where the truth is embraced based on the experience which is symbolized by the position of the main pillar, the position of the king pillar (the pillars' stance) and some other ritual following the construction process.

Published: September 2019

The communities of Sphaeroceridae in burrows of European Rabbit Oryctolagus cuniculus and Red Fox Vulpes vulpes in central Bohemia (the Czech Republic) are described including number, dominance and constancy of species and compared by means of a similarity index. A total of 17 species were recorded from burrows of rabbit and 9 from those of fox. Spelobia talparum (Richards, 1927) and S. pseudonivalis (Dahl, 1909) are considered pholeobiont (= eucoenic) and Spelobia czizeki (Duda, 1918) pholeophilous to pholeobiont species in this habitat. Comparison of these two communities with those recorded from other mammal subterraneous habitats in Europe revealed that most similar are those from the same locality irrespective of the host mammal species or the size of the burrow. The species spectrum of European Sphaeroceridae recorded from mammal burrows is reviewed and discussed. Minilimosina (Minilimosina) speluncana sp. n. is described on males found in rabbit burrow and its relationship and habitat association are discussed.

Killing Weed Seeds with Exhaust Gas from a Combine Harvester
Authors: Jakobsen Klaus , Jensen Jakob A. , Bitarafan Zahra , Andreasen Christian
Published: September 2019

We investigated if hot exhaust gas from a combine harvester could be used to reduce germination or kill weed seeds during the harvesting process. During the threshing and cleaning process in the combine, weed seeds and chaff are separated from the crop grains. After this separation, weed and crop seeds not collected can be exposed to exhaust gas before seeds are returned to the field. Seeds of some common weed species (Alopecurus myosuroides, Centaurea cyanus, Geranium pusillum, Lapsana communis, Lolium perenne, Rumex crispus, Spergula arvensis, and Tripleurospermum inodorum) were treated with exhaust gas at temperatures of 75 °C or 85 °C, 110 °C, and 140 °C for 2, 4, and 6 s, respectively. Afterwards, the seeds were germinated for 16 days. We found that 75 °C and 85 °C were insufficient to significantly reduce germination of the seeds after three durations. Some seeds were still able to germinate after 4 s exposure of 110 °C. An exposure of 140 °C for 4 and 6 s repressed germination of all species. We conclude that there is potential to develop combine harvesters that exploit the exhaust gas to either kill or reduce the ability of weed seeds to germinate before seeds are returned to the field.
Undrained Pore Pressure Development on Cohesive Soil in Triaxial Cyclic Loading
Authors: Głuchowski Andrzej , Soból Emil , Szymański Alojzy , Sas Wojciech
Published: September 2019

Cohesive soils subjected to cyclic loading in undrained conditions respond with pore pressure generation and plastic strain accumulation. The article focus on the pore pressure development of soils tested in isotropic and anisotropic consolidation conditions. Due to the consolidation differences, soil response to cyclic loading is also different. Analysis of the cyclic triaxial test results in terms of pore pressure development produces some indication of the relevant mechanisms at the particulate level. Test results show that the greater susceptibility to accumulate the plastic strain of cohesive soil during cyclic loading is connected with the pore pressure generation pattern. The value of excess pore pressure required to soil sample failure differs as a consequence of different consolidation pressure and anisotropic stress state. Effective stresses and pore pressures are the main factors that govern the soil behavior in undrained conditions. Therefore, the pore pressure generated in the first few cycles plays a key role in the accumulation of plastic strains and constitutes the major amount of excess pore water pressure. Soil samples consolidated in the anisotropic and isotropic stress state behave differently responding differently to cyclic loading. This difference may impact on test results analysis and hence may change the view on soil behavior. The results of tests on isotropically and anisotropically consolidated soil samples are discussed in this paper in order to point out the main features of the cohesive soil behavior.
Effect of Uncertainty in Localized Imperfection on the Ultimate Compressive Strength of Cold-Formed Stainless Steel Hollow Sections
Authors: Shen Yanfei , Chacón Rolando
Published: September 2019

Stainless steel has excellent corrosion resistance properties, considerable long-term durability, and good mechanical strength. Hollow sections are a versatile and efficient form for construction applications. The use of cold-formed stainless steel rectangular hollow section (RHS) and square hollow section (SHS) in construction industry grasps the attention of designers conceiving long-term, cost-effective structures. For cold-formed RHS and SHS, localized imperfection (ω) resulting from rolling and fabrication process is inevitable. ω has inherent variability and has no definitive characterization. In this paper, statistical analysis of the maximum value of ω collected from available experimental data is conducted. A new approach utilizing Fourier series to generate the three-dimensional (3D) models of members with random ω is proposed. Probabilistic studies based on the proposed 3D models are then carried out to evaluate the effect of uncertainty in ω on the ultimate compressive strength of stainless steel columns with cold-formed RHS and SHS. A total of 21 columns that are prone to local buckling reduction are studied. The results show that uncertainty in ω has a considerable influence on the columns with relatively higher cross-sectional slenderness.
Time Frequency Representation Enhancement via Frequency Matching Linear Transform for Bearing Condition Monitoring under Variable Speeds
Authors: Shi Juanjuan , Du Guifu , Ding Rongmei , Zhu Zhongkui
Published: September 2019

Instantaneous frequency (IF) of shaft rotation is pivotal for bearing fault diagnosis under variable speed operations. However, shaft IF cannot always be measured as tachometers are not allowed to be installed in every case due to design reasons and cost concerns. Extracting the shaft IF ridge from time frequency representation (TFR) of vibration signals, therefore, becomes an alternative. Linear transform (LT), such as short time Fourier transform (STFT), has been widely adopted for such a purpose. Nevertheless, the accuracy of extracted IF ridges relies on the readability of TFR. Unfortunately, readability of TFR from STFT is often impaired by the smearing effect caused by non-synchronous frequencies between bases and signal components and limited time frequency resolution capability, which in turn adversely influences the accuracy of IF ridge extraction. To accurately extract IF ridges from vibration signals, this paper focuses on the first factor, which causes the smearing problem, and proposes a method named frequency matching linear transform (FMLT) to enhance the TFR, where transforming bases with frequencies varying with the shaft IF are constructed to alleviate the smearing effects. To construct the transforming bases with frequencies synchronous with shaft IF, a fast path optimization (FPO) algorithm, which generates all possible optimization paths among amplitude peaks and thereby ensures the continuity of extracted IF ridges, is adopted for IF pre-estimation. The TFR with improved readability can be subsequently obtained via FMLT, paving the way for accurate IF ridge extraction. Then, multiple IF ridges can be iteratively extracted using the FPO algorithm. The accuracy of extracted IF ridges before and after TFR enhancement is compared, indicating that the proposed FMLT can enhance the readability of TFR and lead to more accurate IF ridge extraction for bearing condition monitoring.
Summarization of Spanish Talk Shows with Siamese Hierarchical Attention Networks
Authors: González J.-A. , Hurtado L.-F. , Segarra E. , García-Granada F. , Sanchis E.
Published: September 2019

In this paper, we present an approach to Spanish talk shows summarization. Our approach is based on the use of Siamese Neural Networks on the transcription of the show audios. Specifically, we propose to use Hierarchical Attention Networks to select the most relevant sentences for each speaker about a given topic in the show, in order to summarize his opinion about the topic. We train these networks in a siamese way to determine whether a summary is appropriate or not. Previous evaluation of this approach on summarization task of English newspapers achieved performances similar to other state-of-the-art systems. In the absence of enough transcribed or recognized speech data to train our system for talk show summarization in Spanish, we acquire a large corpus of document-summary pairs from Spanish newspapers and we use it to train our system. We choose this newspapers domain due to its high similarity with the topics addressed in talk shows. A preliminary evaluation of our summarization system on Spanish TV programs shows the adequacy of the proposal.
A Robust Adaptive Trajectory Tracking Algorithm Using SMC and Machine Learning for FFSGRs with Actuator Dead Zones
Authors: Jia Lin , Wang Yaonan , Zhang Changfan , Zhao Kaihui , Liu Li , Nguyen Xuan Quynh
Published: September 2019

The actuator dead zone of free-form surface grinding robots (FFSGRs) is very common in the grinding process and has a great impact on the grinding quality of a workpiece. In this paper, an improved trajectory tracking algorithm for an FFSGR with an asymmetric actuator dead zone was proposed with consideration of friction forces, model uncertainties, and external disturbances. The presented control algorithm was based on the machine learning and sliding mode control (SMC) methods. The control compensator used neural networks to estimate the actuator’s dead zone and eliminate its effects. The robust SMC compensator acted as an auxiliary controller to guarantee the system’s stability and robustness under circumstances with model uncertainties, approximation errors, and friction forces. The stability of the closed-loop system and the asymptotic convergence of tracking errors were evaluated using Lyapunov theory. The simulation results showed that the dead zone’s non-linearity can be estimated correctly, and satisfactory trajectory tracking performance can be obtained in this way, since the influences of the actuator’s dead zone were eliminated. The convergence time of the system was reduced from 1.1 to 0.8 s, and the maximum steady-state error was reduced from 0.06 to 0.015 rad. In the grinding experiment, the joint steady-state error decreased by 21%, which proves the feasibility and effectiveness of the proposed control method.

Use of manufactured sand to replace natural sand is increasing in the last several decades. This study is devoted to the assessment of using Principal Component Analysis (PCA) together with Teaching-Learning-Based Optimization (TLBO) for enhancing the prediction accuracy of individual Adaptive Neuro Fuzzy Inference System (ANFIS) in predicting the compressive strength of manufactured sand concrete (MSC). The PCA technique was applied for reducing the noise in the input space, whereas, TLBO was employed to increase the prediction performance of single ANFIS model in searching the optimal weights of input parameters. A number of 289 configurations of MSC were used for the simulation, especially including the sand characteristics and the MSC long-term compressive strength. Using various validation criteria such as Correlation Coefficient (R), Root Mean Squared Error (RMSE), and Mean Absolute Error (MAE), the proposed method was validated and compared with several models, including individual ANFIS, Artificial Neural Networks (ANN) and existing empirical equations. The results showed that the proposed model exhibited great prediction capability compared with other models. Thus, it appeared as a robust alternative computing tool or an efficient soft computing technique for quick and accurate prediction of the MSC compressive strength.
Augmented Aircraft Performance with the Use of Morphing Technology for a Turboprop Regional Aircraft Wing
Authors: Moens Frédéric
Published: September 2019

This article presents some application of the morphing technology for aerodynamic performance improvement of turboprop regional aircraft. It summarizes the results obtained in the framework of the Clean Sky 2 AIRGREEN2 program for the development and application of dedicated morphing devices for take-off and landing, and their uses in off design conditions. The wing of the reference aircraft configuration considers Natural Laminar Flow (NLF) characteristics. A deformable leading edge morphing device (“droop nose”) and a multi-functional segmented flap system have been considered. For the droop nose, the use of the deformable compliant structure was considered, as it allows a “clean” leading edge when not used, which is mandatory to keep natural laminar flow (NLF) properties at cruise. The use of a segmented flap makes it possible to avoid external flap track fairings, which will lead to performance improvement at cruise. An integrated tracking mechanism is used to set the flap at its take-off optimum setting, and, then, morphing is applied in order to obtain a high-performance level for landing. Lastly, some performance improvements can be obtained in climb conditions by using the last segment of the flap system to modify the load distribution on the wing in order to recover some extended laminar flow on the wing upper surface.
Chemosensory Perception: A Review on Electrophysiological Methods in “Cognitive Neuro-Olfactometry”
Authors: Invitto Sara , Grasso Alberto
Published: September 2019

Various brain imaging techniques are available, but few are specifically designed to visualize chemical sensory and, in particular, olfactory processing. This review describes the results of quantitative and qualitative studies that have used electroencephalography (EEG) and magneto-encephalography (MEG) to evaluate responses to olfactory stimulation (OS). EEG and MEG are able to detect the components of chemosensory event-related potentials (CSERPs) and the cortical rhythms associated with different types of OS. Olfactory studies are filling the gaps in both the developmental field of the life cycle (from newborns to geriatric age) and the clinical and basic research fields, in a way that can be considered the modern “cognitive neuro-olfactometry”.

Published: September 2019

At present, preceding vehicle detection remains a challenging problem for autonomous vehicle technologies. In recent years, deep learning has been shown to be successful for vehicle detection, such as the faster region with a convolutional neural network (Faster R-CNN). However, when the host vehicle speed increases or there is an occlusion in front, the performance of the Faster R-CNN algorithm usually degrades. To obtain better performance on preceding vehicle detection when the speed of the host vehicle changes, a speed classification random anchor (SCRA) method is proposed. The reasons for degraded detection accuracy when the host vehicle speed increases are analyzed, and the factor of vehicle speed is introduced to redesign the anchors. Redesigned anchors can adapt to changes of the preceding vehicle size rule when the host vehicle speed increases. Furthermore, to achieve better performance on occluded vehicles, a Q-square penalty coefficient (Q-SPC) method is proposed to optimize the Faster R-CNN algorithm. The experimental validation results show that compared with the Faster R-CNN algorithm, the SCRA and Q-SPC methods have certain significance for improving preceding vehicle detection accuracy.

The underlying mechanism(s) behind the potential carcinogenicity of processed meat is a popular research subject of which the lipid oxidation is a common suspect. Different formulations and cooking parameters of a processed meat product were evaluated for their capacity to induce lipid oxidation. Meatballs made of beef or pork, containing different concentrations of fat (10 or 20 g 100 g−1), salt (2 or 4 g 100 g−1), subjected to differing cooking types (pan or deep frying), and storage times (1, 7, and 14 days), were evaluated using thiobarbituric reactive substances (TBARS). The deep-fried meatball type most susceptible to oxidation was used as the model meat product for testing the lipid oxidation inhibiting capacity of 11 plant materials and extracts, in two concentrations (100 and 200 mg kg−1 gallic acid equivalent (GAE)), measured after 14 days of storage using TBARS. Summer savory lyophilized powder was the most efficient plant material, lowering lipid oxidation to 13.8% and 21.8% at the 200 and 100 mg kg−1 concentration, respectively, followed by a sea buckthorn leaf extract, lowering lipid oxidation to 22.9% at 100 mg kg−1, compared to the meatball without added antioxidants. The lipid oxidation was thus successfully reduced using these natural antioxidants.

Industrial cooking of common octopus (Octopus vulgaris) under well-established procedures is advantageous for current consumers, which demand healthy and convenient food. This work aimed to evaluate the effect of industrial water boiling, without the addition of salt, on the nutritional profile of common octopus. True retentions (TRs) were calculated for essential nutrients and toxic elements. After boiling, the moisture content decreased, resulting in a concentration of other constituents (protein, fat, fatty acids, majority of amino acids, phosphorus, zinc, and iodine). High TRs were obtained for some essential nutrients: 90.2% (eicosapentaenoic acid, EPA), 89.1% (docosahexaenoic acid, DHA), ≥74.6% (indispensable amino acids, IAA), and 86.8% (iodine). In both raw and boiled octopus, polyunsaturated fatty acids (252.2 and 425.1 mg/100 g), leucine (940.1 and 1613.4 mg/100 g), glutamate (1971.5 and 3257.1 mg/100 g), sodium (393.3 and 332.5 mg/100 g), and zinc (12.6 and 16.6 mg/kg) were, respectively, the most abundant fatty acids, IAA, dispensable amino acids, macro, and micro elements. Cadmium, lead, and mercury levels found in boiled octopus were 0.02, 0.10, and 0.08 mg/kg, respectively. The consumption of 150 g (usual portion) of boiled octopus is advisable because it contributes to significant daily intakes of EPA+DHA (>100%), selenium (75.6%), and iodine (12.4%), and 25% of the daily adequate intake of sodium for adults.

A physically active lifestyle incurs health benefits and physically active individuals show reduced reactivity to psychosocial stressors. However, the findings are inconclusive and are based on self-reported physical activity and sedentary time. The present study aimed at studying the associations between psychological stressors (job demand, control, support, JD-C-S) and objectively measured physical activity (PA) on various intensities from sedentary (SED) to vigorous physical activity. The participants were 314 employees from a cross-sectional study. PA data were collected with the accelerometer ActiGraph GT3X (Pensacola, FL, USA), SED data with the inclinometer activPAL (PAL Technologies Ltd., Glasgow, Scotland, UK), and psychosocial stressors with a web questionnaire. Results showed that vigorous-intensity PA was negatively associated with demand (β −0.15, p < 0.05), even when adjusted for the covariates. SED was negatively associated to support (β −0.13, p < 0.05). Stress significantly moderated relations between support and sedentary time (β −0.12, p < 0.05). Moderate PA (MVPA) was negatively associated with demand, but only when controlling for overtime (β −0.13, p < 0.05). MVPA was also negatively associated with control (β −0.15, p < 0.05) but not when work engagement was included in the model. Being more physically active and spending less time sedentary may help to handle job situations with high demand and low support.
The Impact of Voluntary Policies on Parents’ Ability to Select Healthy Foods in Supermarkets: A Qualitative Study of Australian Parental Views

Published: September 2019

Food packaging is used for marketing purposes, providing consumers with information about product attributes at the point-of-sale and thus influencing food choice. The Australian government focuses on voluntary policies to address inappropriate food marketing, including the Health Star Rating nutrition label. This research explored the way marketing via packaging information influences Australian parents’ ability to select healthy foods for their children, and who parents believe should be responsible for helping them. Five 90-min focus groups were conducted by an experienced facilitator in Perth, Western Australia. Four fathers and 33 mothers of children aged 2–8 years participated. Group discussions were audio-recorded and transcribed verbatim and inductive thematic content analysis conducted using NVivo11. Seven themes were derived: (1) pressure of meeting multiple demands; (2) desire to speed up shopping; (3) feeding them well versus keeping them happy; (4) lack of certainty in packaging information; (5) government is trusted and should take charge; (6) food manufacturers’ health messages are not trusted; (7) supermarkets should assist parents to select healthy foods. Food packaging information appears to be contributing to parents’ uncertainty regarding healthy food choices. Supermarkets could respond to parents’ trust in them by implementing structural policies, providing shopping environments that support and encourage healthy food choices.
