Authors: Jia Leilei , Zhong Liguo , Ge Hongkui , Shen Yinghao
Published: September 2022

Crude oil emulsification exists in unconventional reservoirs after hydraulic fracturing. The matching relationship between emulsion particle size and core pore throat is a key indicator for evaluating shale oil mobility. In order to quantify the matching relationship, laboratory emulsification experiments and reservoir pore characterization are carried out in this paper. The results showed that the oil-water ratio, salinity and surfactant had synergistic effects on the particle size of emulsion. When the water phase composition was constant, the particle size of emulsion increased with the increase of water phase. When the salinity of water phase is high, increasing the amount of water phase can form small particle emulsion. When the salinity of water phase is low, reducing the amount of water phase can form small particle emulsion. Small particle size emulsions can be formed when the aqueous phase contains surfactants. Emulsion particle size is mainly distributed in 0-0.2 μm, reservoir pore throat diameter is mainly distributed in 0.5-1 μm, belongs to micro-nano pores, can provide a good channel for crude oil and emulsion migration.

1 INTRODUCTION

Continental shale oil is the most potential and strategic oil replacement resource in China. Among them, the Permian Lucaogou Formation shale oil in Jimusar Sag in Xinjiang has large reserves and is planned to produce millions of tons in recent years (Hu et al., 2020., Hu et al., 2018., Li et al., 2021., Zhang et al., 2021). Jimusar area in Xinjiang belongs to tight oil reservoir, the reservoir pore throat system mainly develops intergranular pores and intergranular corrosion pores, in which the pore formed by partial sand (or sand debris) gap and the contact area of particles constitute the throat, which has good connectivity and connectivity length (Xiao et al., 2021., Zhang et al., 2021., Li et al., 2021., Zhang et al., 2021). The pores of the reservoir provide channels for the migration of water phase and crude oil.

Di  dalam ilmu ekonomi konvensional uang diartikan sebagai setiap alat tukar yang dapat diterima secara umum. Alat tukar itu berupa benda apa saja yang dapat diterima oleh setiap orang dimasyarakat dalam proses pertukaran barang dan jasa. Dalam ekonomi Islam, secara etimologi uang berasal dari kata al-naqdu, pengertiannya ada beberapa makna yaitu: al-naqdu berarti yang baik dari dirham, mengenggam dirham, membedakan dirham, dan al-naqdu juga berarti tunai. Kata nuqud tidak terdapat dalam al-qur?an dan hadist, karena bangsa Arab umumnya tidak menggunakan nuqud untuk menunjukkan harga. Mereka menggunakan kata dinar untuk menunjukkan mata uang yang terbuat dari emas dan kata dirham untuk menunjukkan alat tukar yang terbuat dari perak. Mereka juga menggunakan wariq untuk menunjukkan dirham perak, kata 'ain untuk menunjukkan dinar emas.

The development of a motivation for language learning questionnaire in multilingual South Africa: Context and use
Authors: Mhlongo PraysGod Siphesihle , du Plessis Colleen , Weidemann Albert
Published: September 2022

Survey questionnaires have over time become benchmark measuring instruments used to measure language learning motivation (LLM) in applied linguistics research related to second or additional language teaching. For researchers who wish to study the motivation phenomenon in multicultural and multilingual contexts, however, the problem is that many of the standardized questionnaires such as Gardner's Attitude/Motivation Test Battery (AMTB) were designed to measure students' motivation primarily in Western countries. Therefore, it becomes mandatory for these researchers to devise scales that are contextually more appropriate for measuring students' LLM. Accordingly, this paper aims to contribute to the limited body of knowledge concerning the design of questionnaires for measuring LLM that are applicable to African multilingual settings by proposing a renewal of perspective in this regard. By outlining the rationale for developing a reliable motivation scale that can potentially yield valid and reliable research outcomes in multilingual contexts, the paper aims to demonstrate how the design of inclusive motivation scales can be achieved. Normative procedures or methods involved in developing questionnaire scales are briefly presented, specifically the selection of suitable survey statements, as well as the piloting and refinement of the scale. It is proposed that the scale be used in conjunction with qualitative methods in order to gain a fuller picture of how motivation interacts with other factors and processes in multilingual contexts that require the learning of an additional language.

Mukopolisaharidoze so skupina lizosomskih bolezni kopičenja. Njihova skupna značilnost je pomanjkanje delovanja encimov, ki razgrajujejo glikozaminoglikane, polisaharide, ki se povezujejo s proteoglikani in tvorijo zunajcelični matriks. Ker ni encimov, ki bi glikozaminoglikane razgrajevali, se ti kopičijo v lizosomih in povzročijo njihovo okvaro in zato se okvarijo drugi celični organeli, celice in končno organi. Klinična slika je široka, od nevro-kognitivnega upada, skeletno-mišičnih deformacij in tipičnih obraznih sprememb. Ključno je zgodnje prepoznavanje bolezni, čeprav s trenutno dostopnimi načini zdravljenja bolezni ne moremo ozdraviti, lahko pa le upočasnimo njen potek, kar je najbolj učinkovito v fazi bolezni še pred pojavom simptomov. Obetavni način zdravljenja je gensko zdravljenje, ki nakazuje možnost ozdravitve bolezni.Predstavljamo primer dečka, pri katerem je bil prepoznan zgodnji kognitivni upad in za bolezen tipične spremembe. Napoten je bil v terciarno ustanovo, kjer je bila diagnoza potrjena. Deček je bil julija 2018 zdravljen z eksperimentalnim genskim zdravljenjem v tujini (bolnišnica San Raffaele, Milano, Italija). V opisanem primeru gre po našem vedenju za prvo uspešno izpeljano gensko zdravljenje pri slovenskih bolnikih ter za enega prvih primerov genskega zdravljenja mukopolisaharidoze tipa I v svetovnem merilu. Gensko zdravljenje s tem postaja del nove klinične stvarnosti, kar predstavlja pomemben mejnik za naš prostor. Zaradi naprednih zdravljenj bi bilo v prihodnosti smiselno uvesti presejalno testiranje novorojenčkov za MPS tipa I, ki se pri nas ali v Evropi doslej še ne izvaja. Do tedaj pa ostaja najpomembnejši predpogoj za uspešno zdravljenje zgodnja klinična prepoznava bolezni in napotitev v terciarno zdravstveno ustanovo.
How does quiz activity affect summative assessment outcomes? An analysis of three consecutive years’ data on self-directed learning
Authors: Oh Chi Eun , Hwang Hyunyong
Published: September 2022

Background: We investigated how quiz activities can improve summative assessment outcomes by analyzing the relationship between them.Methods: We used 217 first-year medical students’ medical informatics data from 3 consecutive years. We analyzed summative assessment outcomes between quiz completion and incompletion groups, one-time and multiple-time quiz learning groups, and three combined comparisons between subgroups of quiz learning activity frequencies: 1 versus 2, 3, 4, and 6 (group 1), 1 and 2 versus 3, 4, and 6 (group 2), and 1, 2, and 3 versus 4 and 6 (group 3). We then analyzed correlations between the final quiz scores and summative assessment outcomes.Results: The summative assessment means for students who completed quizzes and those who did not were 87.16±8.73 and 83.22±8.31, respectively (p=0.001). The means for the one-time and multiple-time quiz learning groups were 86.54±8.94 and 88.71±8.10, respectively (p=0.223). The means for combined subgroups were not significantly different between groups (p>0.05), although a statistically significant increasing trend was found from groups 1 to 3 (0.223>0.203>0.075 using the t-test and 0.225>0.150>0.067 using the Mann-Whitney test, respectively). Summative assessment scores were not significantly correlated with quiz scores (r=0.115, p=0.213).Conclusions: Quizzes helped students who used self-directed learning obtain better summative assessment outcomes. Formative quizzes presumably did not provide students with direct knowledge, but showed them their weak points and motivated them to work on areas where their knowledge was insufficient.
Blue rubber bleb nevus syndrome
Authors: Kolansky Zachary , Kolansky Glenn
Published: September 2022

We present an unusual case of a rare vascular disorder known as blue rubber bleb nevus syndrome (BRBNS). While many cases of BRBNS occur sporadically, some have been associated with an autosomal dominant inheritance pattern with a locus on chromosome 9p [1]. Furthermore, BRBNS causes vascular malformations to occur in the skin and the gastrointestinal (GI) tract. GI bleeding is a common cause of morbidity in these patients [2]. This syndrome affects males and females in equal numbers [3]. A nineteen-year-old male presented with several soft, blue, and easily compressible papules on the trunk (Figs. 1 – 3). These papules were painful to palpation and had been present for years. The patient was referred to a dermatologist by the pediatrician as new papules described recently appeared. Additionally, an ultrasound of the trunk interpreted the areas involved as lipomas. The pertinent history includes the diagnosis of BRBNS in the patient’s uncle and diagnosed with BRBNS by the dermatologist. Finally, the patient was referred to gastroenterologist consultation for colonoscopy to evaluate possible vascular malformations in the GI tract.

Published: September 2022

The article presents the results of the research on venia legendi (the right to de­liver lectures at the university) and the status of private docent at the University of Latvia (UL) until 1944. The term «private docent» was used worldwide in the 18th century; it is still in use in Germany, Austria and Switzerland. In Latvia, it was introduced in the 1860s at the first higher education institution established in the current territory of Latvia – Riga Polytechnicum. The terms «private docent» and «venia legendi» were used in Latvia until the end of World War II. In the present study, the author explains how these terms were used at the UL during the interwar period and during World War II considering the empirical data obtained in the course of research of archival documents and library collections. The article provides an overview of the private docents working at the UL from 1919 to 1944 and their activities in this period.

SPA AND WELLNESS TOURISM - THE EXAMPLE OF THE CITY OF SKOPJE
Authors: Postolov Kiril , Postolov Boris
Published: September 2022

Spa and wellness tourism today is a reality that companies engaged in the hotel industry must be aware of when setting up their facilities. It was considered before that this type of tourism is related only to the clientele that uses it for health reasons. It is no longer the case. Other people are potential consumers of this type of tourism. It stems from the fact that consumers who use such services have greater and more sophisticated requirements and want to meet other types of needs. The main thing is that in this process, the additional value must be obtained in which both parties will be satisfied - consumers and providers of these services. This type of tourism, in turn, implies the need for more extensive investment in providing that content, and therefore in that process, there is a need for greater engagement of the community. It means appropriate aid by providing various types of financial assistance - non-repayable funds (grants), loans with lower interest rates and other types of assistance, especially of a logistical nature. Also, there is a need for the proper education of the local tourist workers for providing this type of services, including an appropriate promotion of the broader interested community for the possibility of using spa and wellness tourism in the tourist facilities throughout the calendar year. These were the main reasons for writing this paper, and we focused on assessing the real situation in terms of spa and wellness tourism within the municipality of Skopje. For that purpose, we constructed a survey questionnaire and by analyzing the obtained answers, using appropriate statistical tools and methods, we gained appropriate knowledge regarding the development of this type of tourism to achieve sustainable economic growth.
THE INFLUENCE OF THE SECURITY PERCEPTION OF A TOURIST DESTINATION ON ITS COMPETITIVENESS AND ATTRACTIVENESS
Authors: Šerić Neven , Jakšić Stojanović Anđela , Bagarić Lidija
Published: September 2022

Visitors' impressions of a destination's security have an increasing impact on their visit. It is also evident in the negative trends in visiting destinations where terrorist attacks take place, where the consequences of the migrant crisis are pronounced, including areas where natural disasters occur sporadically due to climate change or where local crime is on the rise, etc. The minds and subconscioussness of tourists naturally influence the choice of the destination they travel to, when they travel, and how long they will stay there. In addition to establishing and maintaining an adequate security system for the tourist destination, it is necessary to continuously monitor visitors' impressions of how safe they feel or what security threats are bothering them. Based on these findings, it is possible to prevent the negative trend in tourist visits due to fears related to personal safety. Raising the security standards of the destination and more effective management of security features in the destination image and brand are just some of the activities employed for this purpose. But the complexity and cost of these activities require rational tactical and strategic decisions in destination security management. The prerequisite for rationality in decision making is information. Therefore, relevant knowledge about visitors' impressions of a destination's security is incredibly crucial for managing destination tourism development. Based on the thus defined subject of the research, the authors aim to analyse the influence of perceptions of safety on the unexpectedly successful tourist season of the city of Split and its surroundings. The focus of the research problem is the impact of destination security impressions when choosing where to travel and how long to stay there.
Učenje stranog jezika elektronskim putem: izazovi i nedostaci izvođenja nastave u vrijeme pandemije virusa Kovid-19

Published: September 2022

Ovaj rad se bavi uticajem pandemije virusa Kovid– 19 na učenje stranih jezika i prelazak sa tradicionalne nastave na nastavu u elektronskom okruženju (online nastava); konkretno, u ovom slučaju, osvrnućemo se na, i problematizovati pitanje izvođenja nastave iz engleskog jezika elektronskim putem na Univerzitetu Sinergija, i implikacije koje ovaj vid realizacije nastave, uveden u novonastalim okolonostima izazvanim pandemijom virusa Kovid-19, ima u procesu učenja stranog jezika. Naglo i nezaustavljivo širenje virusa Kovid-19, koje je otpočelo početkom ove godine, vrlo brzo poprimivši pandemijske, globalne razmijere, ostavilo je neizbrisiv trag na čovjekovu svakodnevnicu i sva područja njegovog dijelovanja. Reprekusije virusa znatne su i sveobuhvatne, a itekakvog odjeka imaju i u oblasti osnovnog, srednjeg i visokoškolskog obrazovanja, što je dovelo do velikih promjena u organizovanju nastavnog procesa i načinu izvođenja nastave. Prelazak sa tradicionalne nastave u učionicama na online nastavu mogao bi znatno uticati na ustaljeni sistem obrazovanja, pa samim tim i nastavni proces učenja engleskog jezika. U svjetlu neophodnosti prilagođavanja na jednu izmijenjenu realnost i uvođenja alternativnih vidova izvođenja nastave, kao i zatvaranja osnovnih i srednjih škola, i visokoškolskih ustanova sredinom marta ove godine, postavlja se pitanje uspostavljanja online nastave kao mogućeg trajnog rješenja, i uticaja koje bi ovakvo rešenje imalo na proces učenja engleskog jezika. U ovom radu ćemo se, s tim u vezi, pozabaviti ispitivanjem modaliteta učenja stranog jezika koji podrazumijeva učenje u elektronskom okruženju i nudi izvjesne prednosti u odnosu na tradicionalno izvođenje nastave, ali koji isto tako sadrži i određene temeljne nedostatke, kako tehničke, tako i suštinske prirode. Pored navedenog, u radu će biti predstavljeno i mišljenje o online nastavi jednog uzorka studenata druge i treće godine Univerziteta Sinergija (Pravni fakultet, Fakultet poslovne ekonomije, Fakultet računarstva i informatike), koji su imali priliku da svoje stavove u vezi sa ovim pitanjem iznesu u esejskom zadataku na temu “Uticaj pandemije na moje školovanje”, zadatom u okviru predmeta Engleski jezik II i Engleski jezik III.

Natural iridium acts as a high-quality activated detector for probing the energy components of a neutron fluence. Measurements of 191Ir(n,2n)190Ir cross sections are carried out near 14 MeV by the activation method based on 93Nb(n,2n)92mNb reaction cross section standard by PD-300 neutron generator DT neutron source. The (n,2n) products are measured by using a calibrated high pure Ge detector. The cross sections of 191Ir(n,2n)190Ir, σm2 and σg+m1, are measured carefully. The 191Ir(n,2n)190Ir cross sections: σm2, σg+m1, σg+m1+m2 and cross section ratio of σm2/σg+m1 are obtained in an energy range of 13.40–14.86 MeV. Experimental uncertainties are in a range of 3.4%–3.5%. The measured cross sections for the reaction of 191Ir(n,2n)190Ir at 14 MeV are σm2 = (136.05 ± 4.93) mb, σg+m1 = (1972.35 ± 67.06) mb, σg+m1+m2 = (2108.40 ± 71.99) mb, and σm2/σg+m1 = 0.0690 ± 0.0024. The present data are compared with the previous experimental data and the ENDF/B-VIII.0 and JEFF3.0/A evaluated data, showing that the experimental data from the literature are in good agreement with the present data for σg+m1, the evaluated data from JEFF3.0/A are underestimated by 5%–20% in comparison with the present data for σm2, the evaluated data from ENDF/B-VIII.0 are underestimated by 10% in comparison with the present data for σm2, and the ENDF/B-VIII.0 data are consistent with the present data for σg+m1+m2. The discrepancies between the data from the literature and the present data are analyzed and clarified. The present data show significant improvement in accuracy in comparison with data from the literature, these results provide more reliable nuclear data for improving the future evaluation.

In cavity ring-down technique,cavity maladjustment has essential effect on the measurement of intracavity loss.Several adjustment criterions had been introduced to achieve the optimal cavity state.However,experimental study has shown that these criterions may correspond to different cavity state,which means there is discrepancy between different criterions.In view of this problem,a model of intracavity propagation of Gaussian beam is established based on the angular spectrum propagation theory.This model is tested by numerical simulation and experimental research together.In the simulation,the true value of intracavity loss can be known beforehand.The two-dimensional angular scanning is carried out for certain cavity mirror.The two-dimensional distributions of the measure value of intracavity loss and the transmission light intensity are obtained simultaneously.These distribution are both nonlinear and multi-extremum,which will doubtlessly increase the difficulty of cavity adjustment.By comparing the distribution results,we do find the discrepancy between the largest transmission light intensity and the least measured intracavity loss.Meanwhile both of these two states may be not corresponding to the true value in fact.After statistical studies,the relative error of the least measured intracavity loss is-37.01±11.79ppm,whereas the relative error of the largest transmission intensity is-2.70±0.89ppm.The criterion of the largest transmission intensity shows better stability and repeatability.This model is further tested in a folded cavity ring-down setup.The similar scanning procedure in carried out.A major problem in the experiment is that the true value of intracavity loss cannot be known.So only the repeatability precision of the measured intracavity loss can be analyzed.The statistical results of the largest light intensity and the least measured intracavity loss are ±29.32ppm and ±70.71ppm,respectively.The criterion of the largest transmission intensity has better repeatability,which is basically consistent with the simulation result.In this way the rationality of this model can be verified to some degree.In this paper,the criterion of the largest transmission intensity is recommended in the cavity ring-down technique.Furthermore,this model can be a reference to the research of intracavity optical field response,intracavity optical field transmission,and the unstable resonator alignment,etc

Duchenne muscular dystrophy (DMD) affects myofibers and muscle stem cells, causing progressive muscle degeneration and repair defects. It was unknown whether dystrophic myoblasts—the effector cells of muscle growth and regeneration—are affected. Using transcriptomic, genome-scale metabolic modelling and functional analyses, we demonstrate, for the first time, convergent abnormalities in primary mouse and human dystrophic myoblasts. In Dmdmdx myoblasts lacking full-length dystrophin, the expression of 170 genes was significantly altered. Myod1 and key genes controlled by MyoD (Myog, Mymk, Mymx, epigenetic regulators, ECM interactors, calcium signalling and fibrosis genes) were significantly downregulated. Gene ontology analysis indicated enrichment in genes involved in muscle development and function. Functionally, we found increased myoblast proliferation, reduced chemotaxis and accelerated differentiation, which are all essential for myoregeneration. The defects were caused by the loss of expression of full-length dystrophin, as similar and not exacerbated alterations were observed in dystrophin-null Dmdmdx-βgeo myoblasts. Corresponding abnormalities were identified in human DMD primary myoblasts and a dystrophic mouse muscle cell line, confirming the cross-species and cell-autonomous nature of these defects. The genome-scale metabolic analysis in human DMD myoblasts showed alterations in the rate of glycolysis/gluconeogenesis, leukotriene metabolism, and mitochondrial beta-oxidation of various fatty acids. These results reveal the disease continuum: DMD defects in satellite cells, the myoblast dysfunction affecting muscle regeneration, which is insufficient to counteract muscle loss due to myofiber instability. Contrary to the established belief, our data demonstrate that DMD abnormalities occur in myoblasts, making these cells a novel therapeutic target for the treatment of this lethal disease.

Are animals’ preferences determined by absolute memories for options (e.g. reward sizes) or by their remembered ranking (better/worse)? The only studies examining this question suggest humans and starlings utilise memories for both absolute and relative information. We show that bumblebees’ learned preferences are based only on memories of ordinal comparisons. A series of experiments showed that after learning to discriminate pairs of different flowers by sucrose concentration, bumblebees preferred flowers (in novel pairings) with (1) higher ranking over equal absolute reward, (2) higher ranking over higher absolute reward, and (3) identical qualitative ranking but different quantitative ranking equally. Bumblebees used absolute information in order to rank different flowers. However, additional experiments revealed that, even when ranking information was absent (i.e. bees learned one flower at a time), memories for absolute information were lost or could no longer be retrieved after at most 1 hr. Our results illuminate a divergent mechanism for bees (compared to starlings and humans) of learned preferences that may have arisen from different adaptations to their natural environment.

Published: September 2022

Morphogenetic events during the development of the fetal ovary are crucial to the establishment of female fertility. However, the effects of structural rearrangements of the ovary and surrounding reproductive tissues on ovary morphogenesis remain largely uncharacterized. Using tissue clearing and lightsheet microscopy, we found that ovary folding correlated with regionalization into cortex and medulla. Relocation of the oviduct to the ventral aspect of the ovary led to ovary encapsulation, and mutual attachment of the ovary and oviduct to the cranial suspensory ligament likely triggered ovary folding. During this process, the rete ovarii (RO) elaborated into a convoluted tubular structure extending from the ovary into the ovarian capsule. Using genetic mouse models in which the oviduct and RO are perturbed, we found the oviduct is required for ovary encapsulation. This study reveals novel relationships among the ovary and surrounding tissues and paves the way for functional investigation of the relationship between architecture and differentiation of the mammalian ovary.
Effects of a Core Strengthening Program on Muscle Activity Patterns, Strength, and Endurance in People with and without a History of Low Back Pain: A Randomized Controlled Trial
Authors: Hatfield Gillian L.
Published: September 2022

Background of Study: Altered patterns of abdominal and low back muscle activity have been reported in people in the sub-acute phase of low back injury. Specifically, higher overall muscle activity and less ability to match activity to task demands have been found. Objective: This study determined if an 8-week group exercise intervention would alter muscle activity, strength, and endurance in people with/without a history of low back pain (LBP). Method: In this randomized controlled trial 46 participants (age 19-55) with a history of LBP were randomized to exercise (LBPEx, n=24) and no-exercise (LBPCon, n=22) groups. 27 participants without a history of LBP (NoLBP) also exercised. 17 LBPEx and 19 NoLBP participants completed the intervention. 19 LBPCon were tested at 8-week follow-up. The exercise intervention was an 8-week, choreographed, 30-minute group exercise intervention (Les Mills CoreTM) focused on building core strength, stability, and endurance. Pre and post-intervention surface electromyograms from abdominal and low back muscles were recorded during a trunk stability task (TST), and analyzed using Principal Component Analysis to extract patterns corresponding to overall amplitude and relative activation during the TST loading phase. Abdominal and back extensor strength and endurance were also measured. Results: It was found that overall abdominal activity decreased for left anterior external oblique (p=0.019 for TST level 3), left lateral external oblique (p=0.012 for TST level 3), and right posterior external oblique (p=0.035 for TST level 3) in LBPEx and for right lateral external oblique (p=0.009 for TST level 2 and p=0.004 for TST level 3) and left posterior external oblique (p=0.014 for TST level 2 and p=0.011 for TST level 3) in NoLBP during the TST. Abdominal strength and endurance, and back extensor endurance increased for LBPEx and NoLBP (p0.05). Back extensor strength increased for NoLBP (p0.05). Relative abdominal activation during the TST level 2 loading phase increased for right upper rectus abdominus (p=0.05), right lateral external oblique (p=0.002), and left posterior external oblique (p=0.006) for NoLBP, and for left anterior external oblique (p=0.042) for LBPEx. Conclusion: Les Mills CoreTM is readily available and may be recommended as a safe, accessible, and effective intervention to increase abdominal strength and endurance, and back extensor endurance, even for people with a history of LBP.
La fábula de la post-dictadura como reingeniería del terrorismo de estado en "Fuerzas especiales" de Diamela Eltit
Authors:   Universidad de Playa Ancha, Cepeda García Cristofer
Published: September 2022

Fuerzas especiales (2013) de la escritora chilena Diamela Eltit es una novela que da a conocer, mediante la narración de un sujeto femenino innominado, el conjunto de violencias que experimentan diariamente los habitantes de los bloques departamentales donde la novela ocurre, y que están acordonados por las fuerzas policiales, constituyendo un estado de sitio en el territorio. El despliegue de esa violencia en el Chile de post-dictadura obedece a una reingeniería del terrorismo de estado que sobre la base de la fábula política del enemigo interno, construye al sujeto criminal. Dicho sujeto, producido dentro del marco general del neoliberalismo, tendría por objeto inducir mediante la puesta en circulación del miedo una determina forma de comunidad que garantice la hegemonía neoliberal. Los efectos de esa política serán especialmente sentidos por los habitantes de las poblaciones descritas en la novela, reorientando las dinámicas de subjetivación y de relación con los otros, dando lugar a comunidades sin identidad, memoria y futuro, vinculadas solo mediante mercados subterráneos de supervivencia donde las fuerzas policiales ejercen control.
Una ráfaga de hijos únicos: "Una vez Argentina" (2003) de Andrés Neuman, "Formas de volver a casa" (2011) de Alejandro Zambra y "El sistema del tacto" (2018) de Alejandra Costamagna
Authors:   Universidad de Chile, Olea Catalina
Published: September 2022

La recurrencia de conceptos como “literatura de los hijos”, “novela de la orfandad” o “relatos de filiación” en la crítica literaria chilena y argentina del siglo XXI sugiere que la mirada retrospectiva sobre el pasado familiar y personal es un rasgo dominante de nuestra narrativa reciente. Este artículo quiere explorar qué posibilidades de abrir futuro podemos encontrar en estas obras. Para ello se examinan dos novelas chilenas y una hispanoargentina: Una vez Argentina de Andrés Neuman (2003); El sistema del tacto de Alejandra Costamagna (2018) y Formas de volver a casa de Alejandro Zambra (2011). Según propondré, Neuman moviliza en su libro valores progresistas y posmodernos y, sin embargo, construye un relato monológico y tradicional. Costamagna, por su parte, recurre al imaginario gótico para narrar una liberación parcial del pasado, al tiempo que combina dos tipos de memoria: la memoria aprendida y la memoria encontrada. Por último, Zambra escapa del “círculo vicioso” de la historia y de las relaciones familiares construyendo un texto recursivo, pero en el que se introducen variantes.

Published: September 2022

Importance

Area-level factors have been identified as important social determinants of health (SDoH) that impact many health-related outcomes. Less is known about how the social vulnerability index (SVI), as a scalable composite score, can multidimensionally explain the population-based cancer screening program uptake at a county level.

Objective

To examine the geographic variation of US Preventive Services Task Force (USPSTF)–recommended breast, cervical, and colorectal cancer screening rates and the association between county-level SVI and the 3 screening rates.

Design, Setting, and Participants

This population-based cross-sectional study used county-level information from the Centers for Disease Control and Prevention’s PLACES and SVI data sets from 2018 for 3141 US counties. Analyses were conducted from October 2021 to February 2022.

Exposures

Social vulnerability index score categorized in quintiles.

Main Outcomes and Measures

The main outcome was county-level rates of USPSTF guideline-concordant, up-to-date breast, cervical, and colorectal screenings. Odds ratios were calculated for each cancer screening by SVI quintile as unadjusted (only accounting for eligible population per county) or adjusted for urban-rural status, percentage of uninsured adults, and primary care physician rate per 100 000 residents.

Results

Across 3141 counties, county-level cancer screening rates showed regional disparities ranging from 54.0% to 81.8% for breast cancer screening, from 69.9% to 89.7% for cervical cancer screening, and from 39.8% to 74.4% for colorectal cancer screening. The multivariable regression model showed that a higher SVI was significantly associated with lower odds of cancer screening, with the lowest odds in the highest SVI quintile. When comparing the highest quintile of SVI (SVI-Q5) with the lowest quintile of SVI (SVI-Q1), the unadjusted odds ratio was 0.86 (95% posterior credible interval [CrI], 0.84-0.87) for breast cancer screening, 0.80 (95% CrI, 0.79-0.81) for cervical cancer screening, and 0.72 (95% CrI, 0.71-0.73) for colorectal cancer screening. When fully adjusted, the odds ratio was 0.92 (95% CrI, 0.90-0.93) for breast cancer screening, 0.87 (95% CrI, 0.86-0.88) for cervical cancer screening, and 0.86 (95% CrI, 0.85-0.88) for colorectal cancer screening, showing slightly attenuated associations.

Conclusions and Relevance

In this cross-sectional study, regional disparities were found in cancer screening rates at a county level. Quantifying how SVI associates with each cancer screening rate could provide insight into the design and focus of future interventions targeting cancer prevention disparities.
