Published: May 2022

This paper deals with various fertilizer influences to draw solutions to the neat CTA/CA, MA/CTA/CA, and the Al2O3/MA/CTA/CA nanocomposite (NC) modified membrane. Also, the applicability of the neat CTA/CA, MA/CTA/CA, and The Al2O3/MA/CTA/CA nanocomposite (NC) modified membrane display high water flux when it used to desalinate brine water sample collected from the brine mid-stream from Mersa Matruh area, North-Western Coast of Egypt. The salinity of the collected sample is 12760 mg/L and PH (8.5) and used as FS, and 1M from different fertilizer draw solutes (DFDS) include KCl, NH4Cl, (NH4)2SO4, and K2HPO4 used as DS. The results reveal that the flux was KCl and NH4Cl (17.8 L/m2.h) and followed by (NH4)2SO4 (17.1 L/m2.h) and K2HPO4 (16.6 L/m2.h) using the natural saline water as FS using Al2O3/MA/CTA/CA NC modified membrane. The reusability test of the synthesised Al2O3/MA/CTA/CA NC modified membrane showed good sustainability during the 1260 min continuous test. The FO application displayed a great potential to be interested in brine wastewater desalination and enhanced water source sustainability to use in agriculture fertigation.

Creativity, innovation, creation and entrepreneurship have become the core driving force of China's economic development and urban transformation in the new era. To promote the sustainable development of the Yangtze River Delta with higher quality, it is necessary to build a community of regional interests, give play to the advantages of regional industries, and form a world-class city cluster with global competitiveness on the basis of grasping the mission, target positioning and strategic path of the Time, with reliance on the region and the whole country, looking around the world and facing the future. This paper analyzed the creative industry development in the 25 major cities of the Yangtze river delta through three indicators, including the international market share index (IMS), trade competitiveness index (TC) and revealed comparative advantage index (RCA). From the two perspectives of creative goods and services, it compared the international competitiveness of creative industry between China and some major countries in the world. Finally, in the background of the digital era, countermeasures were proposed from the perspectives of cross-border integration and symbiotic development of digital economy, digital technology and creative industry, the spatial collaboration and symbiotic development of creative industry of the city cluster in Yangtze River Delta, talent training and intellectual property protection.
Qorluulasupaluk site: an important puzzle piece in the interpretation of the Palaeo-Eskimo cultures in the High Arctic Thule region
Authors: Sørensen Mikkel , Diklev Torben
Published: May 2022

The Qorluulasupaluk site is located in Inglefield Fjord, Thule, northwest Greenland. From a matrix in the coastal erosion zone of the site a substantial amount of artifacts typical of early Palaeo-Eskimo groups has been retrieved. The assemblage documents the presence of Saqqaq, Independence I, Pre Dorset and Greenlandic Dorset groups. With its location in Inglefield Fjord and its substantial inventory of lithics and bone the site is the first to evidence considerable Palaeo-Eskimo use of the central Thule region not related to the North Water Polynya. Five radiocarbon dates evidence that the site has been in use from c. 2200 BC to 200 BC. Four of the dates represents an interval from c. 2200 - 1750 BC, the last is dating the interval c. 350-150 BC. The dating of Qorluulasupaluk is compared with new dates from two other Palaeo-Eskimo sites (Qeqertat and Nuusuarqipaluk) in Inglefield Fjord and are analysed in relation to dating from other Palaeo-Eskimo sites of the Thule region. It is concluded that the Qorluulasupaluk site contributes to a new understanding of the Thule region’s prehistory and that it raises important questions concerning the earliest prehistory in Greenland.
Magnitude-Rupture Area Scaling Derived From Global Earthquakes Of Moderate To Large Sizes: Implications For Seismic Hazards In Indonesia

Earthquake size can be estimated using magnitude-rupture area scaling developed from modelled fault dimensions and measured moment magnitudes. In this study, a measure of a fault plane geometry was provided by rupture area A and the size scaled with moment magnitude Mw. Using global earthquakes datasets containing 90 events with varying magnitudes 4.45 ≤ Mw ≤ 9.20 during years of 1960-2015, we classified the data into separate strike-slip, dip-slip (normal and reverse) and subduction-zone earthquakes. The study aims to search for reliable scaling used for magnitude prediction of earthquakes around the globe for each type of source mechanism. We found from the Mw−A scaling proposed in this study that the magnitude for subduction events was likely to saturate to a maximum value possible Mw ≈ 9.3 at rupture areas much larger than those for strike-slips and dip-slips. This suggests that rocks in the subduction-zone are able to accumulate high stress, implying large seismic energy release via strong ground motion when an earthquake occurs at the plate boundary. Taking into account cases under consideration that included intraplate-fault and subduction processes covering a wide range of magnitudes from moderate to large sizes, the results are relevant to Indonesian tectonic settings, where active crustal faults have been recently found throughout the country and in particular a future megathrust subduction-zone earthquake of Mw ~ 9.0 is possible to occur off the south coasts of Java Island, the most densely populated island in Indonesia. These potential seismic threats call for increasing awareness of disaster preparedness, particularly for local community in regions with a high level of vulnerability to tsunami and earthquake disasters. Therefore, a reliable earthquake early warning is of primary importance, which is best integrated into an existing tsunami early warning for maximum security from future seismic hazards.

Landslide is one of the major disasters that occur in Malaysia. Despite various initiatives undertaken by the government to reduce their occurrences, landslide incidents continue to occur, resulting in loss of life and property. The development process coupled with climate change increases the risk of landslides. This manuscript briefly looks at the causal factors of landslides and identifies requirements for landslide risk management to identify options to strengthen landslide risk management in Peninsular Malaysia. Risk management encompassing identification of hazards, vulnerabilities and exposure of elements can prevent landslides from becoming a disaster. The study conducted, noted that the present approach in landslide disaster management has not fully incorporated the landslide disaster risk management approach. Key aspects such as legislation, institutions, zoning of disaster risk areas, risk transfer mechanisms and financial allocations require serious consideration. The determination of the legal basis to incorporate risk management measures, which will set out the needed mandates, jurisdiction and responsibility is one of the important steps. It will help ensure that decision making processes are risk-based, and strengthen the processes in preparing disaster risk maps, comprehensive databases using landslide inventory and register. It would also help in the preparation of early warning and emergency response systems as well as bolster community involvement, awareness, and public education. These will require a holistic approach in landslide disaster risk management. It will support the effort undertaken by government and stakeholders to incorporate the four priority areas of the Sendai Framework for Disaster Risk Reduction 2015-2030 which can effectively help reduce the risk of landslides.
An Erosional Unconformity At The Top Of The Nyalau Formation Near Bintulu, Central Sarawak (Malaysia): Its Regional Context And Significance

This article documents an erosional unconformity at the top of the Nyalau Formation (Oligocene-Early Miocene) exposed in a road-cut northeast of Bintulu in central Sarawak. The outcrop succession essentially comprises a lower unit of thickly-bedded sandstones representing wave-dominated shoreface facies overlain by fluvio-tidal channel deposits that were deposited following a base-level lowering. This gently tilting sand-rich unit is cut by an irregular concave-up erosional surface, overlain by mudstones and thinly interbedded heterolithics that show large-scale internal stratification indicative of multiple scour-and-fill structures, progradation and/or lateral accretion. The erosional surface separating the two units not only marks a significant shift in sedimentary facies but the fact that it cuts into deformed and tilted strata (Upper Nyalau) suggests that it is an erosional unconformity caused by a tectonic deformational event. Based on regional structural synthesis and stratigraphic evidences, the unconformity probably represents the eroded top of the Nyalau Formation, overlain by a relatively undeformed succession tentatively correlated with the Early-Middle Miocene post-Nyalau formations in the Mukah-Balingian region.

Structural development and complex basin forming mechanism in Pattani Basin may have formed naturally fractured basement reservoirs. The basement of the South Pattani Basin is poorly understood, as a result of low seismic resolution in its deeper part and lack of wells that reach the basement. Hence, seismic interpretation may improve the understanding of South Pattani Basin basement fracture systems. This paper aims to investigate the geological and seismic characteristics of the fractured basement reservoir, identify the relation between basin evolution and fracture network and development, and proposed a play concept for naturally fractured basement reservoir. Seismic attributes exhibit prominent N-S fault and fracture trends in the study area. Three basement high areas revealed that open fractures distribution identified using seismic ant-tracking technology has good correlation with regional maximum horizontal stress direction (N-S), but the intra-basement (central) area exhibits strong alignment with pre-existing fabrics (NW-SE). Open fracture networks in Zone A and B developed around major fault swarm features. Integrated qualitative and quantitative seismic analysis suggests that the three basement high areas have the potential for fractured basement reservoirs, with a complex fracture configuration and development due to poly-phase deformations.
A Stratigraphic Analysis Of The Khasib, Tanuma And Sa’di Formations In The Majnoon Oil Field, Southern Iraq

The carbonate platform is the environment of Khasib, Tanuma and Sa’di formations which were deposited within open shelf settings at the Majnoon oil field in eight microfacies. The deposition, based on the analysis of microfacies, took place within shallow open marine, shoal environment, deep marine and basin environments. Five third order cycles of succession consist in MJ-12 oil well and three third order cycles in the MJ-15 oil well. They represent successive episodes of sea level rise and standstills. The succession in the study area was formed in a high subsidence environment, reflecting the high subsidence as the main controlling factor in the sequence creation. Because of a significant transgression, the Khasib, Tanuma, and Sa’di formations were deposited on an extremely subsidential carbonate base, where sea level succession involved episodes of rise and standstills.
The benefits of open banking to consumers, banks and FinTech companies
Authors:   , Zandamela Danete Higgins
Published: May 2022

This thesis presents a qualitative grounded theory investigation into the possible benefits of open banking for consumers, traditional banks and FinTech companies, with the study exploring the impact of open banking regulation on the banking industry as regulatory actions occur globally, underpinning rapid innovation in banking, and effectively supporting the rise of the FinTech phenomenon. The general views held by traditional bankers on open banking are explored together with the paths available to them, as they seek compliance with recently issued data sharing regulation, and what this may mean for consumers and FinTech companies. The role played by FinTech companies is also explored, including the possible benefits they derive and contribute to banks and consumers. The benefits to consumers are presented based on the findings and the literature, along with the benefits to banks and FinTech companies, based on the research. Purposive sampling was employed, arriving at a representative sample of top banking and FinTech leaders against which a subjectivist approach application of semi-structured interviews was administered. Data analysis and coding generated 4 themes from which emergent theory arose, forming part of the contribution to knowledge. This emergent theory argues that the current structure of bank business models appears unsustainable under consumer-led pressure for innovative and convenient, independent mobile based products; to respond, bank and FinTech collaboration is key. The theory provides a basis for recommendations that form contributions to practice, designed to support banks as they navigate the transformative nature of the open banking regulation before them. These contributions take the form of a two-part model integrated strategic review process by which banks can make better informed decisions, ensuring improved sustainability and systemic stability. Practice recommendations were also provided for the consideration of FinTech companies. Consumers benefit from the posited contribution to practice as the industry reshapes to specifically meet their needs based on collaboration, reduced systemic costs, increased innovation and just sufficient regulation. Whilst regulators were not a focus of this research, significant findings emerged from the data which have been presented, along with a contribution to practice by way of a set of recommendations for the consideration of regulators seeking to develop an appropriate response to the rapid innovation coming from the FinTech companies.
Implementation barriers for management accounting in the public sector
Authors:   , Plötz Joachim
Published: May 2022

The adaptation and implementation of management accounting/Controlling in the public sector was only partially carried out (this has been noted, e.g., by Hirsch, Nitzl & Schauß (2015); Nuhu, Baird & Appuhami, (2017)), and those implementations that were completed exhibited only limited success. In particular, in Germany, the impact of the implementation efforts of controlling has been disappointing. The complexity of implementations of management accounting/Controlling (as noted, e.g., by Granlund, 2001; Gosselin, 1997; Baxter & Chua, 2003) is even more pronounced in public institutions due to the social and political context than in private sector organisations (Hoque, 2014). Implementation barriers, particularly on a personal level in the form of resistance, persistently make an introduction more difficult. The underlying reasons for resistance have been studied just as little (Parvis-Trevisany, 2006; Agasiisti, Catalano & Erbacci, 2018) as the behavioural science aspects impacting the behaviour of actors in the implementation (Parvis-Trevisany, 2006). Hence, there is a need to study particularly the specific motives and behavioural aspects of actors in the public sector (Hoque, 2014); this thesis meets this demand and aims to examine implementation barriers as well as aspects of and reasons for resistance in greater depth. The empirical study is based on the introduction of a complete controlling concept during the refugee crisis. The empirical foundation of the case study involved a combination of interviews and participant observations. They were supplemented by expert interviews in order to increase the significance of the results and to make a comparison of a problematic with a successful introduction. The thesis examines resistance and its triggers on the basis of behavioural reasoning theory and combines it with behavioural science approaches, including cognitive limitations of the individual actors. The resistances and triggers identified in the case study extend the behavioural reasoning theory with additional 'reasons against' for the introduction of management accounting/Controlling. In the case study, the following 'reasons against' were identified: (1.) fear of transparency, (2.) faulty understanding of Controlling (Controlling as monitoring (‘Kontrolle’)), (3.) overwhelming due to insufficient learning process and (4.) overwhelming due to overambitious targets. The resistance behaviour can be explained by cognitive limitations. For example, the phenomena of overly ambitious targets is influenced by the cognitive limitations of the implementing actor in the form of availability and representativeness heuristics as well as anchor effects. In addition, the role of cognitive dissonance and information overload in the implementation process is highlighted and used as an explanatory approach for the resistance that occurs. The study shows also that different resistance behaviours occur under identical conditions.

Published: May 2022

Introduction: Monosodium glutamate (MSG) is known as a flavor-enhancing compound and also the fifth basic taste (umami). About the safety of using MSG as a food additive, some studies show indications that there is no threat and others show the opposite. There is no consensus about the advantages and disadvantages of using MSG. Objective: To systematically review studies in the international literature on the knowledge of the pros and cons of using glutamate in food. Methods: Systematic review of studies published in journals indexed in ScienceDirect and PubMed databases. Articles published until 2020 were included. The aspects involving the advantages and disadvantages were discussed, as well as the health risks related to the MSG intake from diet. Results: The revised studies showed that MSG can reduce the amount of sodium in foods without modifying flavor. Although authorities indicate that MSG is safe for human consumption, some studies highlight that health risk is real. The use of MSG is still controversial because there are some misunderstandings in the applied amounts of MSG absorption and metabolism. Conclusion: MSG is widely applied in industrial and homemade food. The need for further studies is crucial, and aspects such as metabolism and amounts of MSG effectively consumed must be better evaluated.

The (3 + 1) dimensional nonlinear ion acoustic waves in multicomponent complex plasma with Kappa electron distribution are studied in this work. The Zakharov-Kuznetsov (ZK) equation for ion acoustic wave is investigated by the reductive perturbation method. The variation of nonlinear ion acoustic wave with system parameter is obtained. Meanwhile, the Sagdeev potential function is obtained by using the Sagdeev potential method. And the phase diagram in a two-dimensional autonomous system of the multicomponent complex plasma with Kappa electron distribution is studied. Finally, the important influence of system parameter on the phase diagram, the Sagdeev potential function and the propagating characteristics of (3 + 1) dimensional nonlinear acoustic solitary waves are discussed in detail.

Higher requirements for the performances of thin films need to be fulfilled in the rapid development of integrated circuit technology, due to the more complicate structure and smaller size of chips. In plasma-enhanced chemical vapor deposition , high-density and high-performance thin films can be deposited at low temperature, compared with traditional chemical vapor deposition. In this work, a two-dimensional fluid/MC model coupled with the deposition module is used to describe the capacitively coupled SiH4/N2O/Ar discharges as well as the deposition processes, focusing on the influences of the radial position, gas ratio and gas pressure on the deposition of silicon oxide films. The results show that the edge effect which leads the plasma density to rise near the electrode edges gives rise to the non-uniform deposition rate along the radial direction. It is also found that the more N2O and less Ar content in the gas mixture, as well as an increased gas pressure will improve this uniformity. However, an excessive deposition rate will lead to a series of undesirable phenomena, such as “key hole structure”, vacancies and excessive impurities in films. These problems are also troublesome in the microelectronics manufacture processes. More detailed investigation into the deposition mechanism can be expected in the future .

The endocannabinoid system consists mainly of 2-arachidonoylglycerol and anandamide, as well as cannabinoid receptor type 1 and type 2 (CB2). Based on previous studies, we hypothesized that a circulating peptide previously identified as osteogenic growth peptide (OGP) maintains a bone-protective CB2 tone. We tested OGP activity in mouse models and cells, and in human osteoblasts. We show that the OGP effects on osteoblast proliferation, osteoclastogenesis, and macrophage inflammation in vitro, as well as rescue of ovariectomy-induced bone loss and prevention of ear edema in vivo are all abrogated by genetic or pharmacological ablation of CB2. We also demonstrate that OGP binds at CB2 and may act as both an agonist and positive allosteric modulator in the presence of other lipophilic agonists. In premenopausal women, OGP circulating levels significantly decline with age. In adult mice, exogenous administration of OGP completely prevented age-related bone loss. Our findings suggest that OGP attenuates age-related bone loss by maintaining a skeletal CB2 tone. Importantly, they also indicate the occurrence of an endogenous peptide that signals via CB2 receptor in health and disease.

Published: May 2022

Two epigenetic pathways of transcriptional repression, DNA methylation and polycomb repressive complex 2 (PRC2), are known to regulate neuronal development and function. However, their respective contributions to brain maturation are unknown. We found that conditional loss of the de novo DNA methyltransferase Dnmt3a in mouse excitatory neurons altered expression of synapse-related genes, stunted synapse maturation, and impaired working memory and social interest. At the genomic level, loss of Dnmt3a abolished postnatal accumulation of CG and non-CG DNA methylation, leaving adult neurons with an unmethylated, fetal-like epigenomic pattern at ~222,000 genomic regions. The PRC2-associated histone modification, H3K27me3, increased at many of these sites. Our data support a dynamic interaction between two fundamental modes of epigenetic repression during postnatal maturation of excitatory neurons, which together confer robustness on neuronal regulation.
Modified viral-genetic mapping reveals local and global connectivity relationships of ventral tegmental area dopamine cells
Authors: Beier Kevin
Published: May 2022

Dopamine cells in the ventral tegmental area (VTADA) are critical for a variety of motivated behaviors. These cells receive synaptic inputs from over 100 anatomically defined brain regions, which enables control from a distributed set of inputs across the brain. Extensive efforts have been made to map inputs to VTA cells based on neurochemical phenotype and output site. However, all of these studies have the same fundamental limitation that inputs local to the VTA cannot be properly assessed due to non-Cre-dependent uptake of EnvA-pseudotyped virus. Therefore, the quantitative contribution of local inputs to the VTA, including GABAergic, DAergic, and serotonergic, is not known. Here, I used a modified viral-genetic strategy that enables examination of both local and long-range inputs to VTADA cells in mice. I found that nearly half of the total inputs to VTADA cells are located locally, revealing a substantial portion of inputs that have been missed by previous analyses. The majority of inhibition to VTADA cells arises from the substantia nigra pars reticulata, with large contributions from the VTA and the substantia nigra pars compacta. In addition to receiving inputs from VTAGABA neurons, DA neurons are connected with other DA neurons within the VTA as well as the nearby retrorubal field. Lastly, I show that VTADA neurons receive inputs from distributed serotonergic neurons throughout the midbrain and hindbrain, with the majority arising from the dorsal raphe. My study highlights the importance of using the appropriate combination of viral-genetic reagents to unmask the complexity of connectivity relationships to defined cells in the brain.
Does who I am and what I feel determine what I see (or say)? A meta-analytic systematic review exploring the influence of real and perceived bodily state on spatial perception of the external environment
Authors: MacIntyre Erin , Braithwaite Felicity A. , Mouatt Brendan , Wilson Dianne , Stanton Tasha R.
Published: May 2022

Background

Bodily state is theorised to play a role in perceptual scaling of the environment, whereby low bodily capacity shifts visuospatial perception, with distances appearing farther and hills steeper, and the opposite seen for high bodily capacity. This may play a protective role, where perceptual scaling discourages engaging with the environment when capacity is low.

Methodology

Our protocol was pre-registered via Open Science Framework (https://osf.io/6zya5/) with all amendments to the protocol tracked. We performed a systematic review and meta-analysis examining the role of bodily state/capacity on spatial perception measures of the environment. Databases (Medline, PsychINFO, Scopus, Embase, and Emcare) and grey literature were searched systematically, inclusive to 26/8/21. All studies were assessed using a customised Risk of Bias form. Standard mean differences and 95% CIs were calculated via meta-analysis using a random-effects model.

Results

A total of 8,034 studies were identified from the systematic search. Of these, 68 experiments (3,195 participants) met eligibility and were included in the review. These were grouped into the following categories: fatigue; pain; age; embodiment; body size/body paty size; glucose levels; fitness; and interoception, and interoceptive accuracy. We found low level evidence (limited studies, high risk of bias) for the effect of bodily state on spatial perception. There was consistent evidence that both glucose manipulations and age influence spatial perception of distances and hills in a hypothesised direction (lower capacity associated with increased distance and hill steepness). Mixed evidence exists for the influence of external loads, embodiment, body/body-part size manipulations, pain, and interoceptive accuracy. Evidence for fitness and/or fatigue influencing spatial perception was conflicting; notably, methodological flaws with fitness and fatigue paradigms and heterogenous spatial perception measures may underlie null/conflicting results.

Conclusion

We found limited evidence for bodily state influencing spatial perception of the environment. That all studies had high risk of bias makes conclusions about reported effects reflecting actual perceptual shifts (vs merely reflecting experimental demands or error due to inadequate study design) pre-emptive. Rigorous evaluation is needed to determine whether reported effects reflect more than bias (e.g., experimental demands, inadequate blinding). Future work using reliable measures of spatial perception, comprehensive evaluation of relevant confounders, and methodologically robust (and experimentally confirmed) bodily state experimental paradigms is warranted.
Estrategias persuasivas en la publicidad televisiva de alimentos en España

Published: May 2022

Este artículo analiza las estrategias persuasivas empleadas en la publicidad de alimentos en la televisión en España, según su nivel de procesamiento, para conocer las características de los mensajes, los personajes y los recursos audiovisuales. Se analizó el contenido de los anuncios emitidos en las dos cadenas de televisión con más audiencia (Antena3 y Telecinco) durante cuatro días de octubre de 2020. Se analizó un total de 128 horas, de las que se obtuvo un corpus de 111 anuncios. Los resultados arrojan una sobrerrepresentación de anuncios de alimentos ultraprocesados en comparación con los alimentos no procesados. Los primeros emplean más estrategias persuasivas, apelan a la ruta periférica de procesamiento, recurren a más protagonistas de género femenino hipersexualizadas, a personajes famosos y a una mayor cantidad de animaciones, grafismos y efectos de sonido. Se puede afirmar que la promoción de una alimentación saludable presenta debilidades, pues existe una infrarrepresentación de alimentos no procesados en los medios, sumándose al empleo de menos estrategias persuasivas que llamen la atención de la audiencia. Estos resultados permiten recomendar que las autoridades inviertan más esfuerzos en medidas eficientes y contundentes en favor de la alimentación saludable.
La comunicación de los influencers veganos en Instagram: el caso español
Authors:   Universidad de Alicante, Romero-Cantero Tamara
Published: May 2022

El movimiento vegano está en auge debido a la preocupación por el bienestar animal, la sostenibilidad, y los estilos de vida saludable de gran parte de la población mundial. Los influencers veganos, a través de Instagram principalmente, tienen un rol clave en todos los procesos de comunicación concernientes a este movimiento. En este contexto, el objetivo principal de este estudio es analizar la comunicación que realizan en Instagram influencers españoles cuya temática principal es el veganismo. Se seleccionaron cinco perfiles de influencers que fueron analizados mediante análisis de contenido. Por una parte, la investigación señala la infrautilización publicitaria que se realiza de los contenidos publicados por los influencers, así como el hecho de que muchas de las publicaciones no están correctamente mencionadas como contenido publicitario. Se confirma que la temática más frecuente está vinculada con la alimentación (recetas) pero, paradójicamente, solo dos influencers poseen formación en materia de nutrición o similares según la información obtenida. Tampoco se observa que aquellos que no la tienen sustenten la información que publican con alguna base científica. En un contexto comunicativo tan dinámico y cambiante, se considera que los organismos competentes deberían proponer más normas, y más específicas, para proteger al consumidor.

Authors:   Universidad de Costa Rica, Mena Young Margoth
Published: May 2022

Esta investigación tuvo como objetivo caracterizar una muestra de 296 audiovisuales de ciencia en redes sociales de diez instituciones del Sistema Nacional de Ciencia y Tecnología de Costa Rica en 2018 y 2019 y analizar su aporte a la divulgación del conocimiento científico. El estudio sistematizó videos divulgados en Facebook, Twitter, YouTube e Instagram por plataforma, organización, duración, tema, campo disciplinar, personas protagonistas (roles y género), locaciones y otros. Los resultados reflejan la necesidad de diversificar temáticas y áreas del conocimiento en la producción audiovisual y de incluir mayores recursos narrativos, así como la paridad de género. Asimismo, se observa una escasa inversión en recursos multimediales y el apremio por más personal dedicado a producir audiovisuales y manejar redes sociales en las organizaciones estudiadas.
Estrategias de marca territorial en la representación y reputación de territorios en el ámbito del desarrollo regional
Authors: Feijó-de-Almeida Giovana-Goretti
Published: May 2022

Las marcas no son un fenómeno nuevo, pero es reciente el uso de estrategias de marketing en la promoción de marcas territoriales y su implicación en procesos de planificación y desarrollo urbano-territorial. El objetivo de este artículo es comprender las estrategias de las marcas territoriales brasileñas en la representación y reputación de los territorios en el ámbito del desarrollo regional. La metodología incluye investigación aplicada y cualitativa, con énfasis en el estudio de casos múltiples en dos ciudades brasileñas: Porto Alegre y Pelotas. Los resultados indicaron que existen relaciones de poder contenidas en las marcas territoriales y vínculos con la representación y reputación de los territorios, lo que ha generado un nuevo mercado, el mercado simbólico-territorial. Las marcas surgen de una red de relaciones que hacen que los territorios sean más competitivos; sin embargo, los actores sociales han mostrado la existencia de malentendidos en torno al concepto teórico y el uso empírico de estas marcas en la realidad brasileña. La conclusión reitera la existencia de relaciones entre marcas y territorios, las cuales inciden en las dinámicas territorial-regionales y promueven transformaciones socioterritoriales.

La prevalencia de problemas de salud mental en estudiantes universitarios chilenos, junto con el bajo porcentaje de búsqueda de ayuda psicológica, son preocupantes. Al respecto, se han señalado obstaculizadores culturales, psicológicos y clínicos que inciden en el proceso de búsqueda de ayuda psicológica, sin que exista claridad de cómo impactan en este grupo particular. En la presente investigación se identificaron los factores predictores de la intención de búsqueda de ayuda psicológica en una muestra de 99 estudiantes universitarios de la Universidad Católica de Temuco. Los resultados señalan que los mejores predictores para la intención de búsqueda de ayuda psicológica son las creencias culturales positivas que estos jóvenes sostienen en relación a la psicoterapia y las expectativas que tienen respecto de ésta. Dichos hallazgos ponen de manifiesto que factores culturales como las creencias socialmente compartidas sobre la psicoterapia y factores psicológicos como las expectativas, juegan un rol significativo, lo cual es un insumo relevante a la hora de planificar intervenciones destinadas a aumentar los niveles de búsqueda de ayuda psicológica en este grupo.
Interacciones mesero/cliente en Santiago de Chile: expectativas de obtención y normalización de propinas
Authors: Alarcón Molina José Ignacio
Published: May 2022

El artículo describe las dinámicas de entrega y normalización de propinas en la relación mesero/cliente en la ciudad capital de Chile. Para ello, la investigación estuvo anclada en dos antecedentes: (a) las normativas vigentes de la propina, apuntando a la contingencia de su entrega; (b) las investigaciones empíricas que evidencian el trato tangencial e individualista de la propina. Metodológicamente, la investigación se delimitó en los principios etnometodológicos-sistémicos, aplicando observaciones participantes en 4 organizaciones y 16 entrevistas a meseros y clientes. Como resultados, se presentan las características motivacionales - ¿Por qué entregar propina?-, cognitivas - ¿Cómo se incentiva su entrega? - y normalizadoras -¿Cómo se comprende la regularidad de su entrega? A modo de alcances, se presentan las propiedades comunicativas del dinero, y cómo dicho artefacto puede ayudar en la normalización y ampliación de las comunicaciones económicas, aportando nuevas miradas a los estudios que problematizan la distribución del dinero. Por último, como límites de la investigación, se plantea la necesidad de generar investigaciones históricas y semánticas que visualicen el recorrido normativo de la propina, y cómo dicho camino puede explicar y/o desmentir las conclusiones interacciónales del presente estudio.

La importancia de la mediería agrícola como mecanismo de cooperación al interior de la economía mapuche rural contemporánea en el contexto de la comunidad Valentín Marín de Nueva Imperial, IX Región, Chile
Authors: Codoceo Tapia Ricardo
Published: May 2022

En el siguiente artículo se presentan los resultados de una investigación social cualitativa sobre el rol de la mediería agrícola en la economía mapuche rural actual en el contexto de la comunidad Valentín Marín de la comuna de Nueva Imperial. Este artículo comienza identificando desde el punto de vista del actor local, los principales condicionamientos económicos y sociales que presentan las economías mapuches en el sector. Dichos factores inciden para la emergencia de la cooperación en mediería. En segundo lugar se busca determinar la importancia de los factores socioculturales en la organización de estas formas de producción agrícola, destacando el rol de la confianza como mecanismo cultural. En tercer lugar se caracterizan las formas de organizar la producción en base a la mediería, considerando producción de cereales, lupino y papas, los cultivos más desarrollados en la comunidad. En cuarto lugar se aborda la repercusión de esta forma de trabajo al interior de la economía familiar local, destacando su multifuncionalidad. En la discusión, a la luz de los resultados de este trabajo, se problematizan algunos de los principales supuestos y planteamientos que han elaborado distintos autores para comprender esta forma de trabajo agrícola. Se destaca el carácter instrumental de la mediería como mecanismo que beneficia a ambos actores del contrato, destacando la heterogeneidad de formas de organizar la mediería. Una de las conclusiones, es que quizás esta forma de trabajo cooperativo se haya intensificado en el sector estudiado, por la emergencia de nuevos condicionamientos económicos en las economías mapuches
La autogestión en la diversidad económica. Cooperativas, clubes y talleres productivos en la provincia del Marga Marga, región de Valparaíso de Chile

Este artículo presenta los resultados de la comparación de tres tipos de organizaciones autogestionadas que produce bienes y servicios, y su valor puede o no traducirse en precios y en dinero. Además, describe las interacciones que estas organizaciones tienen con los actores económicos y agentes políticos en la provincia del Marga Marga. A nivel conceptual, se utilizan las categorías de comunidad efectiva y sistema ecológico, para interpretar los datos que fueron construidos entre 2016 y 2017, a través de una metodología de estudio de casos. En este ejercicio se buscó responder la siguiente pregunta: ¿qué dimensiones de la autogestión son significativas para comprender la trayectoria de una organización que produce bienes y servicios? Entre los resultados destacó que el mantenimiento de la trayectoria de una organización económica autogestionada adopta dos maneras. Por un lado, las cooperativas y los talleres productivos participan en aglomeraciones de organizaciones productivas y comerciales de pequeña escala. Por otro lado, los clubes y agrupaciones de arte, crecen en sistemas ecológicos homogéneos donde la municipalidad cumple un papel importante.

Araucanía – Comahue: un espacio transnacional de migración en Chile y Argentina
Authors: Sanhueza Díaz Lilian , Chávez Herting Marisol , Douzet Carafi María Teresa , Smythe Bendel Milton
Published: May 2022

Este artículo expone las características de la migración transfronteriza en el territorio Araucanía–Comahue, ubicado en la frontera sur de Chile y Argentina. Hoy en día es conocido como corredor, denominación dada en el marco de políticas de desarrollo impulsadas por los Estados-nación a espacios marginales anexados tardíamente al territorio nacional. Pero cabe destacar que ya en el siglo XVII, este espacio comunicaba y vinculaba a los habitantes del Wallmapu de cada lado de la cordillera de los Andes. Así, el objetivo es describir la movilidad humana indígena documentada por la historiografía y las dinámicas y prácticas transnacionales que se rescatan de las experiencias relatadas por chilenos y argentinos que migraron en esta zona desde mediados de siglo XX y que han utilizado las mismas rutas de los pueblos originarios. La información recabada muestra que esta migración transfronteriza es un fenómeno histórico y vigente que hoy impone desafíos al Estado. Por ello, se propone la noción de corredor humano Araucanía–Comahue que critica y complementa la actual idea de corredor. Si bien ésta reconoce el intercambio histórico, se focaliza en el desarrollo económico y el intercambio de bienes, sin atender a las características de la movilidad humana, las razones históricas de su circulación, las motivaciones actuales y, por ende, las condiciones necesarias para favorecer la calidad de vida de quienes transitan a través del macizo cordillerano.
El simbolismo del agua y de la piedra en karra maw’n, de Clemente Riedemann
Authors: Ariz Castillo Yenny Karen
Published: May 2022

El artículo consiste en un análisis del poemario Karra Maw’n (2015) del valdiviano Clemente Riedemann (1953) desde una perspectiva ecocrítica, que profundiza en la geografía poetizada, en especial, en el agua y en la piedra como elementos que determinan el paisaje. Debido a la violencia ejercida en las luchas territoriales y a partir de la explotación desmedida de recursos, la utilización y el significado socio-cultural de ambos elementos se transforma, lo que provoca la reacción de la naturaleza en forma de terremotos y maremotos; vale decir, los cambios experimentados por el agua y la piedra representan la violencia histórica ejercida en el sur chileno.

El presente artículo, además de discutir los orígenes y aplicaciones del neoliberalismo en América Latina, busca explicar el papel de la reestructuración urbana en la aplicación de políticas neoliberales en ciudades portuarias latinoamericanas. En este sentido, fue desarrollado un análisis bibliográfico sobre los orígenes del neoliberalismo y su comportamiento en Latinoamérica. También fueron realizadas entrevistas con informantes clave que proporcionaron explicar el rol de la reestructuración urbana como parte importante del sostenimiento del sistema neoliberal en ciudades latinoamericanas. Los resultados de la investigación apuntan distintas expresiones del neoliberalismo en las ciudades portuarias de Rosario (Argentina) y Valparaíso (Chile).
