A Spatiotemporal Weighted Regression Model (STWRv1.0) for Analyzing Local Non-stationarity in Space and Time
Authors: Que Xiang , Ma Xiaogang , Ma Chao , Chen Qiyu
Published: March 2020

Abstract. Local spatiotemporal non-stationarity occurs in various natural and socioeconomic processes. Many studies have attempted to introduce time as a new dimension into the geographically weighted regression model (GWR), but the actual results are sometimes not satisfied or even worse than the original GWR model. The core issue here is a mechanism for weighting effects of both temporal variation and spatial variation. In many geographical and temporal weighted regression models (GTWR), the concept of time distance has been inappropriately treated as time interval. Consequently, the combined effect of temporal and spatial variation is often inaccurate in the resulting spatiotemporal kernel function. This limitation restricts the configuration and performance of spatiotemporal weights in many existing GTWR models. To address this issue, we propose a new spatiotemporal weighted regression (STWR) model and the calibration method for it. A highlight of STWR is a new temporal kernel function, in which the method for temporal weighting is based on the degree of impact from each observed point to a regression point. The degree of impact, in turn, is based on the rate of value variation of the nearby observed point during the time interval. The updated spatiotemporal kernel function is based on a weighted combination of the temporal kernel with a commonly used spatial kernel (Gaussian or bi-square) by specifying a linear function of spatial bandwidth versus time. Three simulated datasets of spatiotemporal processes were used to test the performance of GWR, GTWR and STWR. Results show that STWR significantly improves the quality of fit and accuracy. Similar results were obtained by using real-world data for the precipitation hydrogen isotopes (δ2H) in Northeastern United States. The Leave-one-out cross-validation (LOOCV) test demonstrates that, comparing with GWR, the total prediction error of STWR is reduced by using recent observed points. Prediction surfaces of models in this case study show that STWR is more localized than GWR. Our research validates the ability of STWR to take full advantage of all the value variation of past observed points. We hope STWR can bring fresh ideas and new capabilities for analyzing and interpreting local spatiotemporal non-stationarity in many disciplines.

The effect of substituting fishmeal with crustacean (Callianassa) meal in the diets of mixed sex Nile tilapia (Oreochromis niloticus) fry (0.2 g) was evaluated. Three isonitrogenous and isolipidic diets were formulated to contain 30% CP and 15% CL where fishmeal was substituted with Callianassa meal at 0, 25 and 50% in diets R1, R2 and R3 respectively. The experiment lasted for 6 weeks. The stocking density was 10 fish per tank in an isolated system and the capacity of each tank was 50L. Each treatment was administered in duplicates and fish were fed three times per day (09h, 13h, and 17h). The daily ration corresponds to 10% of the live weight of the fish during the first 2 weeks and was reduced to 8% and then 6% for the second and last two weeks of the trial period. At the end of the experiment, fish fed on R1 (control) diet and R2 diet (25% fishmeal replacement) had similar final weight (0.62 g), absolute mean weight gain (0.42 g), relative mean weight gain (210 %) and specific growth rate (2.50 %) and were significantly different from the values obtained from those fed on R3 diet (50% fishmeal replacement). R3 diet had the best FCR (1.42) and was significantly different from the values obtained from R1 and R2 diets but the values of the diets were not significantly different. The dry matter content of the initial fish (96.33%) and those of the R1 (94.12%) and R2 (95.71%) diets did not differ significantly but were slightly higher than that of the value obtained from fish fed on R3 diet (91.15). The protein content of the initial fish (49.63%) was significantly lower than the values obtained from fish fed on R3 diet (61.95%), R1 diet (54.74%) and R2 diet (52.59%). The fat content of the initial fish (41.51%) was higher than the values obtained when fish were fed on the experimental diets. Among the tested diets, the higher the crustacean meal in the diet, the lower the fat content of the fish muscle. The fat content of R1 (control) diet (29.56%) was slightly higher than the value of R3 diet (24.44%) and slightly lower than R2 diet (32.56%). It is concluded that crustacean meal can replace 25% of fishmeal in the diet of Nile tilapia (Oreochromis niloticus) fry at 0.2 g without any effect on the growth performances and feed efficiency.

Authors: Brown Jordan , Washburn Shannon G.
Published: March 2020

The need to focus efforts on preserving the quality and quantity of Kansas' water supply is a widely accepted and growing trend. Addressing such a need will necessitate increased supply of professionals in related STEM fields. Drawing on the Human Capital Theory and the Theory of Work
Adjustment, descriptive survey research and qualitative interviews were used to gather data from employers of water-related job positions. The results of the study suggest that, while employers have not recently experienced much challenge filling job vacancies, demand for employees could increase
in the future. Additionally, employers utilize a variety of professional development resources, and would utilize others if available. While levels of correspondence range among ability requirements and ability sets depending on the job position, efforts in education and recruitment could
help address the supply of candidates for these positions.
O MODUS OPERANDI DO FLUXO MIGRATÓRIO HAITIANO PARA A GUIANA FRANCESA NO SÉCULO XXI
Authors: Gouvêa Ítalo Allan Maia , Isma Adrévil
Published: March 2020

O modus operandi do fluxo migratório haitiano que segue até o departamento ultramarino francês (DUF) da Guiana Francesa (GF) elaborou novas estratégias, mecanismos e rotas ao longo do século XXI, aumentando seu dinamismo depois do terremoto que atingiu o país em 2010. Devido à complexidade das estratégias de mobilidade, faremos uso de distintas teorias, que servirão de arcabouço para a compreensão holística do processo migratório, observando suas dimensões individuais, familiares e comunitárias. O artigo é baseado em pesquisa bibliográfica, levantamento e sistematização de dados e relatos de imigrantes obtidos durante o trabalho de campo. O trabalho encontra-se dividido em três sessões: inicialmente, serão abordadas as imigrações internacionais contemporâneas e a mobilidade haitiana para a Guiana Francesa; a segunda sessão discute a relação entre a sociedade em rede e a institucionalização do fluxo migratório haitiano com destino ao DUF; por fim, será analisada a inserção de um nó à rede da diáspora haitiana, considerando o estado do Amapá como espaço estratégico do fluxo migratório haitiano para a Guiana Francesa.
POLÍTICAS PÚBLICAS E O VOTO: MUNICÍPIOS NORTISTAS E AS ELEIÇÕES PRESIDENCIAIS BRASILEIRAS DE 2002 A 2010
Authors: Sousa Marcos Felipe Rodrigues de , Portéglio Suziany De Oliveira , Ribeiro Gustavo César de Macêdo
Published: March 2020

Considerando um conjunto de políticas públicas como variável explicativa em diálogo com a teoria racional e uma perspectiva sociológica do voto, investigaremos se os municípios nortistas com maiores índices de beneficiários de programas sociais foram consecutivos de uma alta votação no partido governista presidencial em 2002 a 2010. Em 2002, no Partido da Social Democracia Brasileira (PSDB), em 2006 e 2010, ao Partido dos Trabalhadores (PT). Para obtenção dos resultados empíricos, empregamos uma análise descritiva ao segundo turno das eleições presidenciais através de dados da pesquisa de Ribeiro (2014), Censo Demográfico de 2010 e do repositório do Tribunal Superior Eleitoral. Faremos o uso de uma tipologia de classes sociais para averiguar o impacto da clivagem voto e classe nestes municípios. Ainda que os resultados não sejam significativos do comportamento eleitoral dos indivíduos, os municípios que mais receberam benefícios de programas sociais apresentaram grandes índices de votos no partido governista do executivo federal. Entretanto, conclui-se que, apenas a definição de um programa social em específico por um caráter clientelístico ou por apenas uma categorização de racionalidade econômica do voto, deslegitima características sociais e históricas dos eleitores, como seu pertencimento à uma determinada classe social. O contexto político e social deste período proporcionou variações nos índices de votos.
Business Strategy, Accounting Conservatism and Performance
Authors: Li Han
Published: March 2020

This research consists with prior business strategy typology and accounting conservatism theories. It investigates the joint effect of business strategy and accounting conservatism on the firm’s financial performance. The paper finds that accounting conservatism as a prudent accounting reporting principle plays an important corporate governance mechanism. The conservatism can mitigate the negative effect of the aggressive business strategy. The joint effect between business strategy and accounting conservatism is positively related with financial performance. The result is robustness when the different measurements of the strategy and the conservatism are applied. When the firm has weak internal control quality, the joint effect on financial performance also exists significantly.

Authors: Bozkurt Süheyla , Balcı Ali
Published: March 2020

The study aimed to determine how lecturers have adopted organizational democracy and academic freedom in Turkish state universities, as well as to find out their views on its appropriation for Turkey. A correlative descriptive survey model is used in this study. The study sample was included 418 academics working at state universities in Ankara. For this research, an ‘Organizational Democracy Scale’ and an ‘Academic Freedom Scale’ were developed and employed by the researcher, and the obtained data were analyzed using SPSS statistical software. The arithmetic mean and the standard deviation were calculated for the answers provided by the academics. Regression analysis was conducted to find out the effect of organizational democracy on academic freedom. In the qualitative phase of the study, face-to-face interviews were conducted with 20 academics. NVivo 10 software was used to analyze the content of the interviews. At the end of the study, it was found that university administrations should avoid discriminative attitudes; should account for their decisions and implementations; deans and faculty boards should be elected democratically; all stakeholders (apart from academics), including students, should take part in both elections and be involved in management processes; and finally, the election system should be more democratic.

Published: March 2020

The contribution is a consideration of the role of a human body in personal, physical reflections, in the field of art and in media space. The presented text is a thought starting point for a scientific study of the role and forms of the human body in contemporary advertising. In contemporary modern society, there is an increasing interest in the appearance and presentation of the body in its female or male modality. Body image is a complex, dynamic and multidimensional aspect of an individual’s personality, determined by a number of individual and socio-cultural factors. Body image creation takes place under the influence and experience
of information and it can change throughout life. The perception of body image is linked to the general ideas that the culture connects with the ideal form of the body. It is not only a mental image, but also includes an assessment component, an attitude based on cognitive schemes and emotional processing of information with which the individual is confronted

Published: March 2020

The game theory (GT) is not only a part of mathematics, but also one of the most popular optimization techniques supporting decision making. Its achievements are currently used in many fields. However, this theory has a special place in economics and management. Operating on the market, companies make a number of decisions that resemble a game with moves made by players. It turns out that GT can also be successfully translated into management needs. The aim of the article is to answer the question about the possibilities of using game theory in management. A wide range of applications of this theory has been shown. Limitations related to its use in management were also indicated.
Signal classification by similarity and feature extraction with application in automatic insect identification
Authors: Silva Diego , Batista Gustavo
Published: March 2020

Insects have a strong relationship with the human-beings. For example, some species of mosquito transmit diseases that kill millions of people around the world. At the same time, the presence of certain insects is essential for the ecological balance and food production. For this reason, we are developing a novel sensor as a tool to efficiently control disease vectors and agricultural pests without harming other species. In this paper, we demonstrate how we overtook the most important challenge to make this sensor practical: the creation of accurate classification systems. Despite the short duration and the very simple structure of the signal, we managed to successfully identify relevant features using speech and audio analysis techniques. We show that we can achieve an accuracy of 98% in the task of disease vector mosquitoes identification.

The geometries of the title complexes are described by the quantum-chemical approach using input coordinates obtained from the previously synthesized and X-ray characterized diffraction data of [Ca(THEEN)(PIC)](PIC), [Ca(THPEN)(H2O)2](PIC)2, Ba(THPEN)(PIC)2, [Na(THPEN)]2(PIC)2, [Sr(THPEN)(H2O)2]2(DNP)4 and [Ba(THPEN)(H2O)2]2(DNP)4 (where DNP is 3,5-dinitrophenolate). Only the primary coordination sphere of complexes (1–6) is optimized in the gaseous phase. Calculations of the energy gaps of frontier orbitals (HOMO-LUMO), 13C-NMR shifts and vibrational bands are carried out using B3LYP/6-31 g + (d,p)/LANL2DZ level of theory. The calculated geometric and spectral parameters reproduced the experimental data with a well agreement.
Cognitive Hypnotherapy
Authors: Brooker Elizabeth
Published: March 2020

Cognitive hypnotherapy (CH) is an assimilative therapy rooted in cognitive therapy and behavioural therapy, with the addition of hypnosis. It is a psychodynamic therapy that focuses on the unconscious mind (implicit thoughts, actions and emotions) no longer in conscious awareness. This chapter gives a brief synopsis of the hypnotic procedures and protocols that are most pertinent for understanding the case for integration. It gives the background of cognitive behavioural therapy (CBT) and a brief history of how this therapy evolved. It further gives the rationale for the integration of hypnosis with CBT, corroborated with evidence from the literature. CH treatments are documented in some detail in a number of different domains where hypnosis is used as an adjunct to therapy for the treatment of debilitating psychological conditions. The techniques and procedures are designed to desensitise and reprocess dysfunctional cognitions, emotions and memories enabling positive change in cognitive perceptions and visualisation. The author, an academic and experienced clinical practitioner of CH for more than 10 years, recognises that there is much scepticism regarding this therapy. It is hoped that this review will give greater understanding and more credence to this highly effective therapy in both the scientific community and medical profession.
Tools and Protocols for Managing Hyperprolific Sows at Parturition: Optimizing Piglet Survival and Sows’ Reproductive Health
Authors: Björkman Stefan , Grahofer Alexander
Published: March 2020

Genetic selection for higher prolificacy is one of the major causes for a decrease in piglet survival and reproductive health of the sow. Large litters increase farrowing duration and decrease piglet birth weight and therefore have an impact on piglet vitality, colostrum uptake, and piglet survival. Large litters also increase the incidence of postpartum dysgalactia syndrome (PDS) and the probability of the sow to be removed from the herd because of reproductive failure. Therefore, hyper-prolificacy challenges the performance of the sow in terms of parturition, colostrum production, neonatal survival, and fertility. In this review, we discuss the tools and protocols for management of parturition, colostrum, and sows’ reproductive health. We provide checklists for the prevention of birth complications and PDS as well as for improvement of mammary gland development and colostrum production.
Alternative Representation for Binomials and Multinomies and Coefficient Calculation
Authors: Alfredo Sánchez de León José
Published: March 2020

Polynomials play an important role in many fields of mathematics as well as in other areas such as physics and engineering. Binomials and multinomies represent a special kind of polynomials, regarded as a wide frame of study by some mathematical branches such as discrete mathematics. Under this subject a novel method was recently developed that addresses the task of performing the calculation of binomial and multinomial coefficients, by means of the setting of an arrangement of sequences of summations. The document unfolded hereby aims to be an extension of that work. Through this document, firstly it will be deemed an equation resultant from that work, targeted at binomial calculations, and will be extended to the multinomial instance. Afterwards a theoretical case of study will be presented, to expose the application of this framework. And lastly an algorithm will be raised to set it up on a computer algebra system (CAS), and some practical examples will be bestowed.
Hypnosis and Hypnotherapy: The Role of Traditional Versus Alternative Approach
Authors: Hudu Garba Mikail , Mamman Mohammed
Published: March 2020

Hypnosis is a state of mind that is characterized by focused attention and heightened receptivity for suggestions. It is either established by compliance with instructions or achieved naturally; the critical nature of the mind is bypassed during hypnosis and acceptable suggestions are delivered. Misperceptions about hypnosis by clinical practitioners and their clients have been shaped through years of inaccurate but interesting portrayals of hypnosis in books, plays, and movies. Part of the misperceptions is that individuals with seemingly magical powers to manipulate the unsuspecting innocent with their authoritative voice commands and penetrating eyes are depicted as hypnotists. This chapter will review the traditional and conventional approaches used in hypnosis, their advantages and disadvantages as well as where hypnosis is used as a complementary or alternative therapy to the modern day orthodox medicine. Despite the pejorative image display of hypnosis and misconceptions surrounding it, hypnosis still has numerous applications in contemporary medicine. Hypnotherapy conducted by a trained therapist is considered as a complementary or safe alternative to present day orthodox medication for numerous ailments.

Published: March 2020

We present the first results of fission-track dating of apatite monofractions from two rock samples taken from the Southern carbonatite massif of the world’s largest alkaline ultrabasic Guli pluton (~250 Ma), located within the Maymecha-Kotuy region of the Siberain Traps. Based on the apatite fission-track data and computer modeling, we propose two alternative model of the Guli pluton's tectonothermal history. The models suggest (1) rapid post-magmatic cooling of the studied rocks in hypabyssal conditions at depth about 1.5 km, or (2) their burial under a 2-3 km thick volcano-sedimentary cover and reheating above 110°C, followed by uplift and exhumation ca. 218 Ma.
Age of the Early Paleozoic granitoid magmatismin the central part of the Bureya continental massif, Central Asian Fold Belt

Published: March 2020

The article presents new age data on the ‘key’ Early Paleozoic igneous complexes located in the central part of the Bureya continental massif of the Central Asian Fold Belt. Porphyroblastic quartz monzonites of the Kivili complex are dated to 453±2 Ma. The age of gneissic granites of the Sularin complex is ~481 Ma. The Sm-Nd isotope stu­dies show that Late Ordovician quartz monzonites were formed mainly from crustal sources with Paleoproterozoic Nd model isotopic ages. Both ancient (Paleoproterozoic?) and younger sources were involved in the formation of Cambrian granites. Our data, as well as previously published materials, suggest several stages of the Early Paleozoic magmatism in the evolution of the Bureya continental massif: ~541, ~504–500, ~487, ~474 and ~453 Ma. Early Paleozoic magmatism developed under a similar scenario in the Jiamusi continental massif. In addition to the synchronism of Neoproterozoic magmatism within these continental massifs, this feature testifies to their common geological history.
Two episodes of metamorphism in the rocks of the eastern Kitoi block (Sharyzhalgai uplift of the Siberian platform) according to the garnet amphibolite data
Authors: Sukhorukov V. P. , Savel'eva V. B.
Published: March 2020

The Archean metamorphism in the southwestern Siberian craton was confirmed by the studies of the Kitoy and Irkutsk blocks. However, the parameters of the metamorphism process are still poorly investigated. The article presents the first results of studying the metamorphism conditions of garnet amphibolites sampled from the Kitoy sillimanite deposit. The reaction relationships of the studied minerals give grounds to distinguish two episodes of the regional metamorphism. At the end of the first episode, (Т=710–770 °С and Р=8.3–8.8 kb), the pressure reduced to 1.3–2.5 kbar at T=700 °C at the retrograde stage, and amphibole-plagioclase rims formed around garnet grains. During the second episode of metamorphism, the temperature reached 890 °С (granulite facies), and Cpx+Opx paragenesis replaced hornblende. The second episode of metamorphism is not evident in all the samples (considering the same bulk rocks composition of the rocks), which suggests its local character.
Structural and dynamic distribution patterns of oil fields in the central part of the Volga-Ural anteclise
Authors: Kolodyazhny S. Yu. , Nekrasov A. I.
Published: March 2020

Tectonical and development features of the central part of the Volga-Ural anteclise and the Sura-Kama (SK) shear zone are considered in connection with the distribution patterns of oil fields. Based on the geological and structural data, it is found that the SK zone is a deep fault of a heterogeneous structure, which has signs of the long-term multistage development. At the plate stage, the SK zone developed under kinematic inversion and subsequent transpression and transtension deformations. We propose a model showing that during the transtension stages, deformations in the SK zone contributed to the primary migration of hydrocarbons in the Devonian domanic formations and their secondary redistribution. Within the SK zone, permeability was increased, and the zone itself acted as a concentrator of these formations in local decompression structures. Fault structures in the SK zone closed during the transpression stages; their reservoir properties were decreased; and hydrocarbons were squeezed predominantly in the lateral direction along the reservoirs in the area of dynamic unloading. At the eastern termination of the SK zone, the unique Arlan oil field was formed, wherein hydrocarbons were accumulated in conditions of alternating stresses between the sectors compensating shear displacements at the flanks of the zone. The unique Romashkinsky oil field was formed in the apical part of the South Tatar arch during its long-term uplifting and decompression, which contributed to progressive migration and accumulation of hydrocarbons from the transpression sector of SK zone. The proposed structural-dynamic model and ideas about compression – decompression regularities of hydrocarbon redistribution in the shear zones can be used for prediction and detection of new deposits. In particular, the dynamic analogues of the Arlan oil field in the east part of the SK zone can be found within the poorly studied western flank of this zone.

Published: March 2020

Magnetic exploration is the most informational and economical method of prospecting and exploration of iron-ore deposits. In rough-terrain and remote areas without any infrastructure, problems associated with ground-based methods can be avoided by using modern unmanned technologies that allow conducting geophysical surveys in a more efficient way. An unmanned aeromagnetic survey complex (aerial vehicle, UAV) Geoscan 401 was used to assess the possibility of using UAVs for aeromagnetic surveying of iron-ore deposits. Our experimental study was conducted in the well-studied area of the largest iron-ore deposit of South Yakutia. The UAV capacities were confirmed by comparing the aeromagnetic survey data with the available data obtained by ground magnetic exploration of the study area. By analysing magnetic fields, we established that the anomalies detected by the ground and aeromagnetic surveys were fully identical. Furthermore, a weak anomaly was discovered in the northeastern part of the study area (it was not reflected in the magnetic field from the ground survey data). Recalculation of the vertical gradient of the magnetic field shows that the anomaly is caused by a blind ore body. Its upper edge is located at a depth of 200–250 m from the day surface. In calculations for a data array without gradient intervals, a mean square error (MSE) amounts to 1.01 nT. An absolute error in the heights of the working and control flights did not exceed 1.5 m. Both the preliminary and control measurements were performed very efficiently. Profiles for UAV surveys were spaced by 100 m. A 1.0 km2 site was covered by one flight within approximately 20 minutes. The Geoskan-401 UAV is useful for obtaining orthophotos, topographic maps and 3D models of the surveyed territory as required for further studies consistent with the magnetic surveys. The aeromagnetic surveys were followed by trenching to verify the newly discovered anomalies. Based on the results of this experimental study, the forecast resources of the Sutam deposit should be increased by almost 250–350 million tons, i.e. plus 15 % to the previously explored and approved reserves of the Sutam field.

Authors: Graves Myia L. , Nabors Laura A. , Bernard Amy L. , Vidourek Rebecca A.
Published: March 2020

Photovoice is a community-based participatory research method where participants can showcase their life experiences through photography. The objective of this study was to have adolescent girls attending an after-school program use photovoice to represent their perceptions of physical activity practices. Photovoice was used to allow adolescent girls to express their perspectives, through photographs and narratives, of their personal and community strengths and concerns related to their involvement in physical activity. The phenomenological methodology was used as a framework for the study. Qualitative analyses were conducted throughout the research process. Constant comparison was used to analyze the focus group, scrapbook data, and notes recorded by the author to determine key themes and ideas. Participants for the study included 14 girls attending a school in an urban area. Benefits of physical activity as provided by the girls in their personal lives and the community included: understanding activity contributed to wellness, increased social opportunities, and the school as a hub of activities. Personal and community barriers to physical activity included: lack of neighbourhood safety, being involved in other sedentary activities, parental rules restricting outside play, outside conditions, personal choices to not exercise, and a lack of opportunity to exercise. Potential ways to increase physical activity among these participants are to create more group games and activities at the after-school program daily. Involving parents in activities with the girls at home may increase physical activity levels while at home.
Assessing MyPlate Familiarity and Typical Meal Composition using Food Models in Children Aged 7-13
Authors: Willis Jada L. , Howe Carol J. , Alexander Gina K.
Published: March 2020

The Dietary Guidelines for Americans serve as a basis for developing federal nutrition education materials for the public, such as MyPlate. MyPlate is a visual cue that uses food groups as a guide to building healthy plates at mealtime. The objective of this study was to determine factors associated with child familiarity with MyPlate guidelines and to determine if typical meals met MyPlate guidelines using food models. A convenience sample of 250 children (aged 7-13 years) and their parent/guardian were recruited at a local science and history museum. Children viewed a picture of the MyPlate icon and were asked to identify the picture. Next, participants used a nine-inch plate to build a typical meal (meals that they would regularly consume) from a buffet of food and beverages models (>65 items to choose from). Research team members took photographs of the plates. A Registered Dietitian Nutritionist determined the percentage of plates that met MyPlate guidelines. Eighty-six percent of children recognized the MyPlate icon upon viewing the image; 7.6% could accurately identify the icon by name. When participants were asked to build a typical meal, however, only 3.43% met MyPlate guidelines. The results of this study suggest that despite being familiar with MyPlate, children built typical meals that did not meet MyPlate guidelines.
Factors Associated with Breastfeeding Patterns in Western Saudi Arabia: A Literature Review
Authors: Shahbar Anwaar , Eid Noura M.S.
Published: March 2020

According to literature initiation of breastfeeding is common but exclusive breastfeeding is last one month post delivery in most Saudi women, where continuation to exclusively breastfeed is still challenging. This review discussed breastfeeding patterns, factors associated, and possible approaches to prolong breastfeeding duration in Saudi Arabia. Our review has shown that the early introduction of formula makes the mixed-feeding the most popular feeding method used among the Saudi population. The most frequent reason reported was insufficient milk followed by medical and lifestyle factors. Younger, employed, and higher-educated women were found to be less likely to breastfeed therefore a greater effort probably is required with those women. According to literature, the Baby-Friendly Hospital Initiative (BFHI) was found to be an effective tool in increasing breastfeeding duration worldwide, in Saudi Arabia only one study has published and found that BFHI is effective in initiating breastfeeding but formula was introduced after hospital discharge. We recommend increasing Saudi women's confidence about breastfeeding, educating them and introducing other strategies such as peer counselling.
Natural Antioxidants and Vitamins Supplementation Shelters Adolescents from Upper Respiratory Tract Infection
Authors: Chahine Nathalie , Nader Moni , Chalhoub Wissam , Chahine Ramez
Published: March 2020

Context: Several decades of dietary research recommended the consumption of antioxidants and vitamins rich foods as a protective tool against a broad portfolio of diseases
Aims: This study aims to test if oral supplementation of natural antioxidants and vitamins before the winter season, may reduce the occurrence of upper respiratory tract infection (URTI) in adolescents.
Settings and Design: Natural antioxidants and vitamins supplements were given to 90 adolescents (45 males, and 45 females) from an orphanage against a placebo during three months in a double-blind fashion.
Methods and Material: Saliva was collected before and after supplementation. The antioxidant activity of saliva was determined in vitro using electrolysis as a free radical generating system. Additionally, total antioxidant activity, glutathione and ascorbic acid levels in the saliva were evaluated before and after supplementation. The URTI frequency was recorded throughout the winter season (3 months).
Statistical Analysis: All values were expressed as means ± SEM. Significance of the results was assessed using Student's t-test and Fisher’s test
Results: Data indicated that only five individuals from the group that received antioxidants and vitamins supplements manifested URTI while 14 adolescents from the non-supplemented group showed symptoms of URTI. Biochemical analysis revealed that the saliva in provenance from the supplemented group exhibited a higher capacity to scavenge free radicals compared to its capacity before supplementation. This supplementation also increased the total antioxidant activity and the levels of both ascorbic acid and glutathione in the saliva.
Conclusions: We concluded that oral intake of antioxidants and vitamins protects against URTI through increased antioxidant activity.

Discipliner les corps reproducteurs pour la santé de qui ?
Authors: Jarty Julie , Fournier Tristan
Published: March 2020

Cadre de la recherche: À partir d’un
cadre théorique et conceptuel issu de la sociologie et des études sur le genre,
cet article analyse la promotion d’un récent programme international de santé à
l’intention des femmes et des enfants dont l’argumentaire scientifique
s’enracine dans le domaine de l’épigénétique. Il serait désormais possible, en
intervenant de façon précoce sur l’environnement (nutritionnel) des individus
durant les périodes préconceptionelle et périconceptionnelle (la grossesse et
les deux premières années de vie des enfants), de prévenir l’apparition de
pathologies chroniques à l’âge adulte.

Objectifs: Il s’agit ici de retracer
l’historique de cette biopolitique (Foucault, 2004),
d’en décrire son processus de légitimation, et ce afin d’interroger d’importants
enjeux sociaux qui en découlent notamment sur le plan de nouvelles normes et
injonctions autour de la production d’enfants (sains).

Méthodologie: Pour ce faire, nous
déployons une méthodologie associant revue de littérature scientifique et grise,
ethnographie de l’ONG états-unienne 1,000 Days et
entretiens semi-directifs auprès d’experts internationaux (OMS, USAID, Unicef,
Sun).

Résultats: Nous montrons que ce
programme contribue à l’assise d’une morale profondément inégalitaire qui
s’appuie d’abord sur une promesse médicale, mais s’adosse en parallèle à une
promesse économique : un corps en meilleure santé serait garant tant de la
productivité des enfants, alors pensés comme des adultes en devenir, que des
saines finances des nations, notamment les pays des Nords.

Conclusions: En creux d’un programme
focalisé sur la santé des jeunes enfants et des nations émerge un « dressage »
des corps en gestation, et tout particulièrement des corps des femmes
subalternes : obèses, racisées, malades ou pauvres.

Contribution: Cet article démontre les
apports de la contribution scientifique des sciences sociales et des études sur
le genre, aux recherches médicales sur la santé des enfants ainsi qu’à leur mise
en politique.
Contrôle du poids des enfants et activité physique dans un quartier populaire strasbourgeois : modèles familiaux et recommandations de santé publique
Authors: Grassler Marine , Knobé Sandrine , Gasparini William
Published: March 2020

Cadre de la recherche : En devenant une priorité des politiques de santé publique en France, la prévention du surpoids et de l’obésité infantile a donné lieu à de nombreux programmes et actions publiques à l’échelle locale. C’est le cas de la ville de Strasbourg qui, dès 2014, a mis en place un dispositif de prévention intitulé « PRise En Charge Coordonnée des enfants Obèses et en Surpoids de Strasbourg » (PRECCOSS) destiné aux enfants âgés de 3 à 12 ans.

Objectifs : À partir d’une approche sociologique croisant l’analyse des acteurs et celle des dispositifs, l’article interroge la réception de la politique locale de lutte contre le surpoids par les enfants et leurs familles résidant en quartier populaire. L’objectif est de mieux comprendre les rapports pluriels à un dispositif visant le corps de l’enfant et ses effets.

Méthodologie : Une enquête sociologique qualitative, combinant entretiens semi-directifs et observations, a été réalisée auprès de dix familles dont au moins un des enfants était en surcharge pondérale et incité à participer au dispositif PRECCOSS.

Résultats : L’analyse comparée de familles participant ou non au dispositif permet de mettre en exergue les conflits de légitimité auxquels sont confrontés les parents, notamment les mères, entre les recommandations de santé publique en matière de lutte contre la sédentarité et les schèmes familiaux d’exercice du rôle de parent, de comportements alimentaires et de mode de vie liés à la culture d’origine.

Conclusions : En visant à réduire le décalage entre le modèle corporel dominant promu par les politiques de santé publique et la culture corporelle de ces familles, le dispositif de prise en charge de l’enfant dans sa corporéité oriente l’action familiale mais rencontre également des formes de résistance.

Contribution : Ces résultats viennent affiner et nuancer les analyses qui présentent souvent les classes populaires, par comparaison avec les classes plus favorisées, comme moins promptes à mettre en pratique les prescriptions normatives.
Le bien-être de l’enfant : évolution
d’une notion, ambiguïtés des dimensions et mesures
Authors: Martin Claude , Perron Zoé , Buzaud Julia
Published: March 2020

Cadre de la recherche : Cet article
propose une revue de la littérature sur les déterminants et la mesure du
bien-être des enfants, et une analyse secondaire de bases de données
internationales dans le but de repérer des questions encore relativement
inexpliquées.

Objectifs : Il vise à proposer des
hypothèses pour expliquer les écarts entre le niveau d’investissement public
dans des politiques visant les enfants et leur niveau de bien-être
subjectif.

Méthodologie : Cette enquête repose sur
une revue de questions et des analyses secondaires de bases de données
internationales.

Résultats : L’article met en lumière
l’importance de la communication entre parents et adolescents dans le sentiment
de bien-être subjectif exprimé par les adolescents.

Conclusions : Des recherches
qualitatives et comparatives sont nécessaires pour mieux saisir les mécanismes
en cause.

Contribution : Les travaux
de la chaire CNAF-EHESP « Enfance, bien-être, parentalité » sur lesquels
s’appuient cet article permettent de s’interroger sur l’engouement actuel pour
les questions de bien-être et de bonheur des populations afin d’améliorer leur
compréhension par les sciences sociales
Transformational Kinstellatory Relations and the Talking Stick Festival
Authors: Lachance Lindsay , Couture Selena
Published: March 2020

This article charts the development of, and connections created through, the Vancouver-based Talking Stick Festival to inform how performance- making and gathering over shared interests can maintain artistic relationships and nurture respectful intercultural relations. We demonstrate this through genealogically connecting the Talking Stick Festival to the 1997 Festival of the Dreaming in Sydney Australia linking this theoretically to Indigenous ideas of transformational love, “grounded normativity” and kin relations that cross earthly boundaries. We examine the strategic ways that the annual festival builds networks of communication, including movement around territories, and the valuing of flexibility to honour accountability. And, of immense value to the rebuilding of broken kinship networks is the love and support for emergent artists as well as staff and volunteers who are mentored in the ever-expanding and continuous building of relations. We write explicitly from our own positions and discuss how we, the co-authors of this piece, have ourselves been transformed through interactions with the festival as a way to show how this kind of relationship building can create a shared future. We conclude that the organizers of the Talking Stick Festival create spaces that centre Indigenous resurgence through personal experiences of transformation and kinstellatory relations of co-resistance.
Majdi Bou-Matar’s Impact
Authors: Houston Andrew
Published: March 2020

The IMPACT Festival is an event dedicated to theatre that centralizes marginalized voices to address social issues, and in the process, works to constitute a vibrant intercultural community. At once a festival, a conference, and an opportunity for artists, scholars, and other cultural commentators—from international to local—to meet and engage with one another, IMPACT has happened biannually in Kitchener, Ontario since 2009. Yet despite its award-winning status among scholars and artists, the IMPACT Festival has struggled to be embraced by either the City of Kitchener or the citizens of the Region of Waterloo. Beginning with interviews with local theatre creators, and drawing on the intercultural analysis of Ric Knowles and Bruno Latour, among others, this article is an attempt to understand why the IMPACT Festival has encountered obstacles to sustainable success in its home town.
Un Sant Jordi de cine
Authors: Lalueza Ferran
Published: March 2020

Entre la bigarrada programació de festivals cinematogràfics celebrats a Barcelona (focalitzats gairebé sempre en àmbits temàtics ben específics i gaudint moltes vegades de suport institucional), l'any passat va obrir-se pas una iniciativa engrescadora: el Festival Internacional de Cinema de Barcelona - Sant Jordi. De caràcter generalista i promogut enterament per entitats privades, l'anomenat BCN FILM FEST busca ara la seva consolidació a través d'una segona edició que s'inaugura aquest 20 d'abril i que presenta 38 pel·lícules.
