Published: December 2020

Background

Systemic lupus erythematosus (SLE) patients often suffer hand function limitations even in the absence of symptoms related to joint or tendon disorders. Recent researches reported the presence of ultrasonographic (US) subclinical synovitis and tendon involvement in asymptomatic patients. We aimed to assess US patterns in SLE patients and determine their relationship with clinical assessment, disease activity and hand functional status using handheld dynamometry.

Results

We assessed 30 SLE patients (60 hands) using US; 21 (70%) patient had synovial hypertrophy, 8 (26%) showed a power Doppler (PD) activity, 6 (20%) had erosions and 11 (36.6%) had tendon US abnormality. Both patients with hand arthralgia/arthritis (symptomatic) and patients without arthralgia/arthritis (asymptomatic) had a statistically insignificant difference regarding the global synovitis score (p= 0.2) and disease activity (p= 0.3). However, the symptomatic group had a significantly increased number of joints with effusion (p= 0.04) and tendons involved (p= 0.04). The mean grip strength had a significant negative correlation with SLEDAI-2 K score (rs = − 0.4,p= 0.02) in the total patient group. In the asymptomatic group, a negative correlation was found between both mean grip (rs = − 0.5,p= 0.04) and pinch strength (rs = − 0.6,p= 0.01) with PD index, and mean pinch strength with the Jaccoud’s arthropathy index (rs = − 0.49,p= 0.05).

Conclusions

SLE patients may have higher subclinical synovitis, erosions and tendon involvement than expected, which may in turn reduce hand grip and pinch strength. Disease activity may also have a negative impact on the hand grip functional strength.

Introduction: Over 40 million deaths annually are due to noncommunicable diseases, 15 million of these are premature deaths and physical inactivity contributes an estimated 9% to this figure. Global responses have included the Sustainable Development Goals (SDGs) and the Global Action Plan on Physical Activity (GAPPA). Both point to policy action on physical activity (PA) to address change, yet the impact of policy on PA outcomes is unknown.  The protocol described outlines the methodology for systematic literature reviews that will be undertaken by the Policy Evaluation Network (PEN) to address this knowledge gap.

Methods: The seven best investments for promotion of population PA identified in the Toronto Charter highlighted seven policy domains (schools, transport, urban design, primary health care systems, public education, community-wide programmes and sport) which will form the basis of these PEN reviews. Seven individual scientific literature searches across six electronic databases will be conducted. Each will use the key concepts of policy, PA, evaluation and a distinct concept for each of the seven policy domains. This will be supplemented with a search of the reference list of included articles. Methodological quality will be assessed and overall effectiveness for each included study will be described according to pre-determined criteria.

Conclusions: Each review will provide policy makers with a list of policy statements and corresponding actions which the evidence has determined impact on PA directly or indirectly. By collating the evidence, and demonstrating the depth of the science base which informs these policy recommendations, each review will provide guidance to policymakers to use evidence-based or evidence-informed policies to achieve the 15% relative reduction in physical inactivity as defined by GAPPA.

Authors: Panina Elena , Belyaeva Elena
Published: December 2020

Systemic osteoporosis is a progressive multifactorial metabolic disease of the skeleton that requires active therapy to prevent low-energy fractures. When patients with comorbidity seek medical care at the stage of development of complications, the selection of therapy can be difficult. In case of ineffectiveness and / or contraindications to the use of drugs of certain pharmacological groups, treatment may be prescribed using not only antiresorptive and bone-metabolic drugs in monotherapy, but also their combination.
Conflictos políticos en las ciudades castellanas durante la Baja Edad Media: La lucha por el poder en Guadalajara (1350-1450).
Authors: Plaza de Agustín Javier
Published: December 2020

El presente artículo pretende describir cómo evolucionó el gobierno de la ciudad de Guadalajara durante la Baja Edad Media a través del análisis de las disputas políticas entre caballeros y pecheros, así como estudiar el papel que jugaron en tales conflictos tanto la Corona como la poderosa familia Mendoza. Este periodo de constantes enfrentamientos finalizó con la derrota pechera y con la instauración del regimiento en Guadalajara, controlado por el estamento de los caballeros, quienes a su vez acabaron formando parte de la red clientelar de los Mendoza, que llegó a dominar el municipio como si fuera uno de sus señoríos.
Administración y poder local en Castilla en el siglo XVIII: Jurisdicción, concejo y señorío en Segovia.
Authors: Pousa Diéguez Rodrigo
Published: December 2020

La administración territorial castellana giraba en su base en torno a dos esferas de poder estrechamente vinculadas: la jurisdiccional y la concejil. El territorio de la España moderna se presenta compartimentado en un número todavía desconocido de jurisdicciones y concejos. El presente trabajo pretende ofrecer una visión integral de la división administrativa segoviana, que pasa por el conocimiento de sus jurisdicciones la titularidad de los territorios, el número de concejos y sus oficiales al cargo. El resultado de este trabajo arrojará luz sobre el grado de señorialización experimentado por la provincia en comparación con otras, la capacidad de las comunidades rurales y urbanas para constituir asambleas independientes para el autogobierno y su sujeción al poder señorial.
Tax Misperceptions and the Effect of Informational Tax Nudges on Retirement Savings
Authors: Blaufus Kay , Milde Michael
Published: December 2020

Despite subjects being informed about tax rules before making saving decisions, we find—using laboratory experiments—that deferred taxation results in after-tax pensions that are approximately 25% lower compared with an economically equivalent immediate pension-tax system. This indicates substantial tax misperceptions. For subjects with low tax knowledge, tax misperceptions remain stable, even if they have gained experience. Tax misperceptions nearly disappear for all subjects only if we provide recurrent numerical informational pension-tax nudges and if subjects have gained experience. We demonstrate that replacing the tax-deductibility of retirement savings with government matching contributions increases after-tax pensions above the level under immediate taxation without the need to provide informational tax nudges.

It matters what designs design designs: speculations on multispecies worlding
Authors: Westerlaken Michelle
Published: December 2020

Critical contemporary discourses on extinction, climate change and planetary boundaries are needed to counter and reject our current ways of living on this planet. But they often end badly. Therefore, we also need to tell the stories that create openings and generate more desirable alternatives. This paper contributes to the effort of resituating design as less anthropocentric and much more of a multispecies affair. Following scholars such as Donna Haraway, Timothy Morton, Anna Tsing and John Law, this text does so by unpacking the notion of ‘multispecies worlding’ for speculative design practices that involve other living entities. By carrying multiplicities into design processes and rethinking how other species can become a more deliberate part of our (re)worlding efforts, this text articulates the importance of advancing decolonial design aims to generate interspecies harmonies rather than reinforcing oppressive relations. The annotated illustrations and examples of multispecies design projects that appear in this paper involve an additional effort in identifying ‘big-enough’ stories and already existing multispecies design speculations. As such, this work offers merely one collection of enactments that can allow further worlding and further design work. Such a repertoire of speculative multispecies design work can thereby knot together different realities, from different actors, that can propose and embody other kinds of worlding relations between species. They thereby slowly but steadily break down existing grand narratives that seem all-explanatory to speculate about different ways in which humans and other species already make worlds together.
Displaying intimate friendships: Chinese children’s practices of friendships at school
Authors: Zhu Yan
Published: December 2020

Through an intensive ethnographic fieldwork, this project explores rural Chinese children’s understandings and experiences of peer friendships at school. When talking about ‘friend’ and ‘friendship’, children tended to brag that they were friends with many peers, but at the same time to particularly highlight a very small number of peers as the most intimate friends, in other words, their ‘best friends’. Inspired by Finch’s concept of ‘display’, this article explores how these Chinese children used different approaches to highlight their intimate friends’ particularity in intimate friendship displays at school. This article, first, unpacks three commonly used approaches in these children’s displays of intimate friendships: 1) building up an exclusionary ‘intimate friends only’ policy; 2) imparting to certain objects, actions and language sentimental and specific meanings as ‘tokens’ of their friendship; and 3) giving ‘priority’ to intimate friends. Second, it discusses the importance of audiences and cooperation between actors in intimate friendship displays.
Interferometric grazing incidence test of rough steep convex spherics: experimental data analysis
Authors: Rothau S. , Mantel K. , Lindlein N.
Published: December 2020

Grazing incidence interferometry has been applied to plane, cylindrical, acylindrical, and general rod-like surfaces using diffractive beam splitters. Here, in a first step towards measuring aspherics, we demonstrate that also rough convex steep rotationally symmetric spherics can be measured along one meridian in a single step using diffractive beam splitters and phase shifting techniques. The measurement of rough surfaces is possible, i.e., without the need to polish the surfaces, due to the large effective wavelength (

) of the test. We include, besides the short recapitulation of the measurement principle and experimental setup, a presentation of the measured data of one small meridian region for the special case of spherical objects under test. The subsequent data analysis combined with suitable simulations focuses on elimination of the misalignment aberrations from the results caused by specimen displacements in the setup.
High-accuracy and high-repeatability measurement of the cut error of a
nonlinear uniaxial crystal
Authors: Lu Qi , Liu Shijie , Zhang Xiangchao , Xu Tianzhu , Pan Jingyu , Xu Min , Shao Jianda
Published: December 2020

To accurately determine the optical axis cut error of a nonlinear uniaxial crystal, a measurement method based on dual-optical path second-harmonic energy (SHE) rocking curve acquisition is presented, of which the measurement uncertainty can be controlled within 3.20 µrad , 26 times higher than that of a high-precision commercial x-ray diffractometer (XRD). To meet the measurement requirements, a Type I potassium dihydrogen phosphate reference crystal (RC) is first made, and its optical axis cut error is considered as a reference. Then, the optical axis cut error of a measured crystal (MC) with an aperture of

and a thickness of 10 mm is determined by simultaneously recording the SHE scatter plots of the RC and the MC, where the measurement repeatability of 10 consecutive measurements is only 4.48 µrad and the measurement speed is within 20 s. During data processing, a third-order Fourier polynomial is proposed to fit the scatter plots into smooth curves, of which the regression coefficients are greater than 0.9975. The experimental method not only overcomes the shortcomings that XRDs will introduce scratches and defects to the crystal surface and are unable to measure large-aperture crystals, but can be used to guide the production of precise cutting of a nonlinear uniaxial crystal, thus ensuring the maximum conversion efficiency of a frequency multiplication system.
Interferometric method of measuring external cylindrical
surfaces
Authors: Zhou Qing , Wang Junhua , Xu Min
Published: December 2020

A new method of measuring external cylindrical surfaces is proposed,
making use of a ring beam transform unit. The unit is composed of
three cone mirrors, with which a parallel beam can be transformed into
annular and convergent beams. The method has advantages over classic
methods: It avoids physical contact with the cylinder surface and is
fast and stitching-free. In experiments using a dynamic interferometer
to demonstrate the feasibility of the method, the RMS difference of
the axis contour from results using a Luphoscan is 0.0282 µm, while
the roundness difference of the circumferential contour is
0.0962 µm.
Multi-criteria decision making based on induced generalized interval neutrosophic Choquet integral
Authors: Jiao Yangyang , Wang Lu , Liu Jianxia , Ma Gang
Published: December 2020

In this paper, two new aggregation operators based on Choquet integral, namely the induced generalized interval neutrosophic Choquet integral average operator(IGINCIA) and the induced generalized interval neutrosophic Choquet integral geometric operator(IG-INCIG), are proposed for multi-criteria decision making problems (MCDM). Firstly, the criteria are dependent to each other and the evaluation information of the criteria are expressed by interval neutrosophic numbers. Moreover, two indices which are inspired by the geometrical structure are established to compare the interval neutrosophic numbers. Then, a MCDM method is proposed based on the proposed aggregation operators and ranking indices to cope with MCDM with interactive criteria. Lastly, an investment decision making problem is provided to illustrate the practicality and effectiveness of the proposed approach. The validity and advantages of the proposed method are analyzed by comparing with some existing approaches. By a numerical example in company investment to expand business though five alternatives with considering four criteria, the optimal decision is made.
Intraretinal microvascular changes after ERM and ILM peeling using SSOCTA
Authors: Told Reinhard , Georgopoulos Michael , Reiter Gregor Sebastian , Wassermann Lorenz , Aliyeva Leyla , Baumann Lukas , Abela-Formanek Claudette , Pollreisz Andreas , Schmidt-Erfurth Ursula , Sacu Stefan
Published: December 2020

Background

To prospectively investigate retinal vascular changes in patients undergoing epiretinal membrane (ERM) and internal limiting membrane (ILM) peeling using swept source optical coherence tomography angiography (SSOCTA).

Methods

Consecutive patients were grouped based on ERM severity and followed using SSOCTA up to month 3 after surgical intervention. Superficial and deep foveal avascular zone (s/dFAZ) as well as foveal and parafoveal vessel density (VD) were correlated with ERM severity and visual acuity. Differences between groups were evaluated.

Results

Significant correlations were found between ERM severity and baseline sFAZ, dFAZ and best corrected visual acuity (BCVA), central retinal subfield thickness (CST) and ΔCST (r = -0.52, r = -0.43, r = -0.42, r = 0.58, r = 0.39; all p<0.05). Vascular flow parameters did not correlate with age, peeling size, pseudophakia or CST, but correlated with intraretinal cysts presence. No associations of BCVA with any of the OCTA parameters across time were found.

Significant differences between ERM severity groups 1 and 2 were found for sFAZ at baseline (p = 0.005) and at the 3-month follow-up (p = 0.014), and for dFAZ at baseline (p = 0.017). Superficial foveal and parafoveal VD were not significantly different between groups (all p>0.05).

Conclusions

This study clearly shows that ERM severity based on ERM staging has to be taken into account when undertaking studies in patients with idiopathic ERM using SSOCTA. Further, specific changes in the superficial and deep retinal vasculature in eyes undergoing ERM and ILM peeling were found. However, the clinical usefulness and prognostic value for post-surgical treatment BCVA of the SSOCTA-derived variables (sFAZ and dFAZ area, as well as foveal and parafoveal VD) used remains questionable.
Spatial distribution and associated factors of underweight in Ethiopia: An analysis of Ethiopian demographic and health survey, 2016
Authors: Tusa Biruk Shalmeno , Weldesenbet Adisu Birhanu , Kebede Sewnet Adem
Published: December 2020

Background

Underweight is one form of indicators of under-nutrition, which results from the poor nutrient intake and underlying health problems. Its impact is beyond an individual and extends to a country level. It has been known from the literature that underweight has a negative effect on income and development of a country. In the context of Ethiopia, factors predicting underweight remain unknown and there is a paucity of evidence on geographical distribution of underweight among individuals aged 15–49 years. Therefore, the aim of this study was to examine the geographic distribution of underweight and its associated factors among individuals aged 15–49 years in Ethiopia.

Methods

Secondary data analysis was done on a data set consisting of 28,450 individuals and obtained from the Ethiopian Demography and Health Survey (EDHS) 2016. The spatial distribution of underweight across the country was identified by ArcGIS software. Hotspots analysis was done using Getis-Ord Gi* statistic within ArcGIS. In SaTScan software, the Bernoulli model was fitted by Kulldorff’s methods to identify the purely spatial clusters of underweight. A binary logistic regression was applied to determine factors associated with being underweight.

Result

In Ethiopia, the spatial distribution of underweight was clustered with Global Moran’s I  =  0.79 at p-value < 0.0001. The highest underweight clusters were observed in Tigray, Gambella, eastern part of Amhara, and western and central part of Afar regions. Male individuals [AOR = 1.21; 95% CI: (1.15 1.28)], never married [AOR = 1.14; 95% CI: (1.05, 1.24)], rural residents [AOR = 1.32; 95% CI: (1.18, 1.47)], rich [AOR = 0.85; 95% CI: (0.76, 0.94)], cigarette smoking [AOR = 1.25; 95% CI: (1.07, 1.46)], drinking treated water [AOR = 0.91; 95% CI: (0.83, 0.99)] and open filed defecation [AOR = 1.17; 95% CI: (1.08, 1.26)] were found to have a significant association with being underweight.

Conclusions

There was a significant clustering of underweight among individuals aged 15–49 years. Gender, age, marital status, place of residence, wealth index, cigarette smoking, using untreated water and types of toilet were the significant factors of being underweight. Therefore, effective public health interventions like building safe and supportive environments for nutrition, providing socio-economic protection and nutrition-related education for poor and rural resident would be better to mitigate these situations and associated risk factors in hot spot areas. In addition, policymakers should strengthen and promote nutrition sensitive policies and activities in order to alleviate the underlying and basic causes of underweight.
Effect of different carbon dioxide (CO2) flows on trapping Aedes albopictus with BG traps in the field in Zhejiang Province, China
Authors: Wu Yuyan , Wang Jinna , Li Tianqi , Liu Qinmei , Gong Zhenyu , Hou Juan
Published: December 2020

Carbon dioxide (CO2) attracts host-seeking adult mosquitoes; this fact is exploited for mosquito monitoring, which is important for evaluating the effects of mosquito-control operations. A field experiment was designed to explore the relationship between the CO2 flow rate and the trapping effect of BG traps. The aim was to select an appropriate flow rate for monitoring Aedes albopictus. Six sampling sites were selected for field experiments in Hangzhou city, Zhejiang Province, China. A total of six CO2 flow rates (0.00 L/min, 0.075 L/min, 0.15 L/min, 0.30 L/min, 0.60 L/min and 1.20 L/min) were tested to compare their effects on mosquito trapping. The catches were performed in six trapping periods between 15:30 and 18:30, and each catch period lasted 0.5 h. A total of 3068 adult mosquitoes were captured at six sampling sites in six days using BG traps (with BG-Sweetscent), among which 86.96% were Ae. albopictus. The total number of Ae. albopictus (males and females) captured at a flow rate of 0.00 L/min was significantly lower than the numbers captured at 0.075 L/min, 0.15 L/min, 0.30 L/min, 0.60 L/min and 1.20 L/min (P<0.001, P<0.001, P<0.001, P<0.001, and P<0.001 respectively). The total number of Ae. albopictus captured and the number of Ae. albopictus females captured increased with increasing CO2 flow and peaked at 0.3 L/min, above which these capture numbers did not increase significantly. In conclusion, the appropriate CO2 flow rate for monitoring Ae. albopictus with BG traps was 0.3 L/min.
Interactive documentaries and health: Combating HIV-related stigma and cultural trauma
Authors: Villanueva Baselga Sergio
Published: December 2020

Interactive documentaries have been growing in number and importance on the international scene in numerous fields and markets. Interactive documentaries entered the field of health about a decade ago, and since then they have proven to be a worthwhile tool for exploring various health issues, such as living with HIV. More recently, experts and academics have started to explore interactive documentaries dealing with a newly emerging topic – stigma. Stigma has negative consequences in every aspect of a person’s life. When it comes to health, people with stigmatized conditions have the worst outcomes, a problem ultimately related to their own power and agency. The media and culture are two structural sources of stigmatization, and cultural trauma has been suggested as one of its mediators. This study seeks to examine interactive documentaries as a tool for raising awareness of the impact of HIV-related stigma and cultural trauma. To this end, it analyses two interactive documentaries, Vertical/Horizontal and The Graying of AIDS, focusing on the device, narrative and textual elements used by these documentaries to deal with the impact of stigma in health, and elaborating on how these cultural productions represent people living with stigma and whether that representation challenges or reinforces stigmatization.
Higher education community engagement as a pathway to developing global citizenship practices in young people: South African perspective
Authors: Machimana Eugene Gabriel , Ebersöhn Liesel , Sefotho Maximus Monaheng
Published: December 2020

The aim of this study is to discuss how South African higher education (HE) is a mechanism to enable global citizenship. This qualitative secondary analysis study draws on retrospective qualitative case study data generated by multiple partners (parents, teachers, young people, HE students, researchers) in a long-term community engagement (CE) study in a remote high school. Thematic analysis of data sources (verbatim transcriptions of participatory reflection and action discussions, and visual data) enabled in-depth multi-partner descriptions on the utility of CE to address social and cognitive injustices given extreme structural disparity and social disadvantage. It was evident that, across CE partner groups, HE involvement was viewed as a mechanism to promote the positive social development of young people. In particular, when young people were included in CE, their social development was supported as they were afforded opportunities to develop capacity as future leaders and in terms of language development in multilingual spaces. We argue that CE can support progress towards social and cognitive justice by offering alternate views and beliefs to young people that promote their global citizenship practices.

Hope and Inevitability in 13 Reasons Why. A Comparative Discourse Analysis of the Series’ First Season and it’s Neyond the Reasons Documentary Counterpart
Authors: Gelado-Marcos Roberto , Poch-Butler Santana Lois , Moreno-Felices Plácido
Published: December 2020

The release of 13 Reasons Why in March 2017 attracted not only audiences worldwide, but also a considerable amount of academic attention. A good share of the academic production on the series, though, have focused mostly on its effects. For this reason, and in an attempt to approach the debate from complementary angles, this paper aims at examining the motivations expressed by those involved in the creative process of the show and compared them with the actual discourse in the series’ first season. In order to do that, the methodology triangulates between quantitative and qualitative techniques to approach the research problem from equally complementary angles. The results of these analyses confirm that the creators’ motivation go beyond the mere entertainment, but also inconsistencies between the discourses in Beyond the Reasons and 13 Reasons Why’s first season.
Artvertising o el arte como reclamo en la publicidad: el caso de la campaña ‘preciobajismo’ de la empresa Lidl
Authors: Jiménez Marín Gloria , Bellido Pérez Elena
Published: December 2020

El arte es un poderoso medio de comunicación utilizado en numerosas campañas publicitarias para atribuir, generalmente, valores de exclusividad al producto anunciado. Este texto analiza una campaña concreta donde el arte se utiliza como reclamo publicitario para remitir al bajo precio comunicando que dicho producto no pierde su calidad. Se trata de la campaña ‘Preciobajismo’, realizada para la cadena Lidl en España. Mediante un análisis del discurso se estudia cómo se ha introducido el concepto de arte en esta campaña. La finalidad es ilustrar diferentes materializaciones de intertextualidad arte-publicidad en una campaña, que, a priori, parece apartada del sentido de prestigio habitual del uso del arte en publicidad. En general, podría afirmarse que en esta campaña aparecen todos los tipos de intertextualidad arte-publicidad descritos por autores de referencia, planteando la relación específica del producto con el arte. Así, en el spot se identifican, representan, mencionan o sugieren artistas, obras, movimientos y museos concretos. Asimismo, Lidl presenta un movimiento artístico asociado a la razón de ser de su entidad y su campaña: sus bajos precios, a través del movimiento de ficción ‘Preciobajismo’, presentando todas las variables de cualquier movimiento artístico: nombre, filosofía, lugar, artistas, críticos y obras de arte.

CONTRIBUIÇÕES DA LITERATURA REGIONALISTA NA FORMAÇÃO DO PENSAMENTO GEOGRÁFICO NO AMAZONAS
Authors: Souza Matheus Pinto de , Dos Santos Sousa Isaque , Patrícia Melo de Lima Susane
Published: December 2020

O presente artigo pauta-se na elucidação das bases de formação do pensamento geográfico no Amazonas, considerando a literatura regionalista do período anterior à institucionalização dos primeiros cursos de geografia no Brasil e no Amazonas. Através do método geo-histórico, levantamento e análise bibliográfica, buscou-se identificar como os textos clássicos elaborados por viajantes e exploradores que descreveram a Amazônia, registrando os eventos num determinado espaço e tempo na região, consolidaram-se como registros fundantes do pensamento geográfico no Amazonas. Evidencia-se assim, que as bases que respaldam este momento da geografia tornam-se importantes para compreender que tal ciência lança mão da relação homem-meio, sociedade-natureza, logo, adotando como pilar as dinâmicas da natureza e da sociedade, bem como os processos históricos, econômicos, políticos e territoriais, que correlacionados, embasaram a evolução do pensar e fazer geográfico, até o momento da institucionalização do primeiro curso superior de geografia no Estado do Amazonas, na década de 1980. A literatura regionalista ganha evidência ao apontar as descrições marcadas pelo empirismo e naturalismo, acerca do espaço e da espacialidade, e ainda, possibilita uma leitura de caráter geográfico que permitem o estabelecimento de balizas analíticas para este espaço-tempo.
The Effect of Women's Financial Self-Efficacy on Financial Product Ownership
Authors: Anastasia Njo , Lestaritio Mellicha Jeni
Published: December 2020

The government is intensively implementing formal and informal education to improve individual financial literacy. This study aims to examine the effect of women's financial self-efficacy on financial product ownership, controlling for contributing to financial literacy, financial risk preferences, and demographic factors. The sample consists of 253 female respondents who live in Surabaya and already have financial products. The data are collected using questionnaires and processed using binary logistic regression. The results show that women's financial self-efficacy significantly affects the choice of financial products in the form of investment, credit cards, and other loans. However, it does not significantly affect the choice of financial products in the form of savings, mortgages, health insurance, and life insurance. This study is expected to provide benefits in developing learning methods to appropriately improve women's financial literacy according to the available financial product choices. Besides, this study is also expected to provide advice to female clients to diversify their investment product portfolios according to their personalities to achieve their financial goals.

Published: December 2020

This paper presents an assessment of capacitor banks and Distribution Static Compensator (D-STATCOM) with respect to their impact on energy quality. Tests were done with capacitor banks built with electrolytic capacitors commonly used in industrial applications and a D-STATCOM. Experimental tests were performed for power factor correction in order to reduce the reactive power demanded from the electrical grid for inductive-resistive loads. For comparative purposes, the control of the D-STATCOM was set to operate with similar compensation conditions to that of the capacitor banks. Results show that under the same test conditions capacitor banks produce higher Total Harmonic Distortion (THD) than D-STATCOM.
WILLINGNESS TO PAY UNTUK PENGEMBANGAN FASILITAS AGROWISATA KECAMATAN BANDUNGAN KABUPATEN SEMARANG (Studi kasus di Setiya Aji Flower Farm)
Authors: Susilowati Indah , Mardiana Ike , Mukson Mukson
Published: December 2020

Semarang Regency has a great agro-tourism potential. Volcanic soil suitable for planting and cool temperatures support it to be a place of recreation. The study was conducted at Setiya Aji Flower Farm (SAFF), a chrysanthemum agro-tourism in Jetis village, Bandungan District, which is managed by farmer groups and local communities. The management is still very simple by utilizing the pre-harvest chrysanthemum flowers for tourism. SAFF was able to bring in 107,966 tourists during 2017, with an entrance ticket currently at Rp 7,500 generates substantial additional income for the people of Jetis village. Unfortunately, the number of tourists decreased until 65% to an average of 3,127 tourists per month in 2018. One of the causes of the reduction in tourist visits was the unpreparedness of the SAFF to face of competition with new tourist objects with similar themes around SAFF that were very well managed and continued growing. The purpose of this study was to estimate the willingness of visitors to pay for additional facilities at SAFF Bandungan, Semarang Regency. This study used the Contingency Assessment Method (CVM) to 110 visitors. The results showed that the majority of visitors are willing to pay for additional facilities at SAFF agrotourism. Willingness to pay (WTP) is estimated at level Rp 13,000. These results provide insights to the manager of SAFF to raise the entrance ticket by adding facilities at SAFF.

Ikan nila (Oreochromis niloticusmerupakan salah satu hasil perikanan air tawar unggul yang terjangkau sebagai komoditas program nasional untuk dijual di pasar domestik dan luar negeri, sehingga perlu adanya pemenuhan permintaan pasar. Budidaya padat tebar tinggi dapat meningkatkan produksi, namun dapat meningkatkan limbah nitrogen yang dapat menyebabkan lambatnya pertumbuhan bahkan kematian pada ikan. Sistem resirkulasi akuakultur dapat memperbaiki dan menggunakan kembali air dengan filter mekanik dan biologi. Spons dapat menyaring dan menahan kotoran, arang memiliki pori halus yang dapat menyerap molekul polutan air, serta zeolit memiliki struktur pori yang mampu bertukar ion. Kombinasi filter tersebut baik untuk memperbaiki kualitas air, sehingga perlu adanya kajian aplikasi komposisi filter agar dapat memperbaiki kualitas air, pertumbuhan dan kelulushidupan ikan nila. Tujuan penelitian ini yaitu untuk mengetahui pengaruh serta komposisi filter terbaik terhadap kualitas air, pertumbuhan dan kelulushidupan ikan nila. Penelitian ini menggunakan 20 ekor ikan setiap wadahnya dengan ukuran 8 cm dan bobot 10,23±1,6 g. Penelitian ini menggunakan metode eksperimen rancangan acak lengkap (RAL), 4 perlakuan 3 ulangan. Komposisi filter yang digunakan yaitu kontrol (A), 25% arang + 75% zeolit (B), 50% arang + 50% zeolit (C), dan 75% arang + 25% zeolit (D). Data yang dikumpulkan yaitu kualitas air, nilai pengurangan total amonia nitrogen (TAN removal), volumetric TAN removal (VTR), total kelimpahan bakteri, laju pertumbuhan relatif (RGR), total konsumsi pakan (TKP), rasio konversi pakan (FCR) dan kelulushidupan (SR). Hasil penelitian menunjukkan bahwa aplikasi komposisi filter berpengaruh nyata terhadap TAN removal, VTR, total kelimpahan bakteri, RGR, TKP, FCR dan SR, perlakuan terbaik terdapat pada komposisi filter 25% arang + 75% zeolit (B) yaitu  97,53%, 50,69 g m-3 day-1, 2,35 x 104 CFU mL-1, 238,33 g, 2,67% day-1, 1,47 dan 95%.Kata Kunci : Ikan nila, sistem resirkulasi, komposisi filter, spons, arang kayu, batu zeolit.

Published: December 2020

Budidaya udang windu dengan sistem IMTA yaitu mengkombinasikan dua atau tiga komoditas budidaya, dimana limbah nutrisi/pakan dari hewan tingkat tinggi dikonsumsi oleh hewan tingkat rendah. Budidaya sistem IMTA saat ini belum banyak diketahui nilai C/N dalam memenuhi persyaratan yang optimal. Bakteri heterotrof di perairan akan tumbuh dengan baik apabila rasio C/N bernilai 10 atau lebih. Oleh karena itu, perlu dilakukan analisis rasio C/N dalam air pada budidaya dengan sistem IMTA (Integrated Multitrophic Aquaculture). Penelitian ini bertujuan untuk mengetahui pengaruh kepadatan udang windu terhadap rasio C/N dalam air dan mengetahui kepadatan udang windu yang optimal untuk menghasilkan rasio C/N pada lingkungan budidaya. Udang windu dengan stadia PL-30 (0.092±0,84 cm) dibudidayakan pada sistem IMTA dengan menggunakan ikan nila dengan kepadatan 20 ekor/m3 (0.69±0,3 cm), rumput laut dengan kepadatan 100 g/m2 dan kerang hijau dengan kepadatan 90 g/m2 (3,32±0,79 cm). Pakan udang windu yang digunakan memiliki kandungan  protein 40% dengan metode pemberian pakan secara fix feeding rate. Pakan ikan nila yang digunakan memiliki kandungan  protein 30% dengan metode pemberian pakan yang diberikan secara ad satiation. Wadah yang digunakan adalah menggunakan bak fiber dengan ukuran panjang 1 m2dan lebar 1 m2dan kedalaman air 0,7 m2. Media yang digunakan untuk membuat sebuah ekosistem yang menyerupai ekosistem tambak ditambahkan substrat berupa pasir berlumpur. Substrat berupa lumpur berpasir mengacu pada penelitian. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) 4 perlakuan dan 3 ulangan. Kepadatan yang digunakan yaitu perlakuan A (tanpa udang), B (60), C (80), dan D (100). Data yang diamati adalah rasio C/N, laju pertumbuhan spesifik (SGR) dan kelulushidupan (SR). Hasil penelitian menunjukkan bahwa kepadatan udang windu yang berbeda pada sistem IMTA berpengaruh (P<0,05) terhadap kelulushidupan tetapi tidak berpengaruh terhadap rasio C/N dan laju pertumbuhan spesifik. Perlakuan kepadatan udang windu 60, 80 dan 100 ekor mempunyai hasil rasio C/N yang baik dalam persyaratan rasio C/N air.Kata Kunci : IMTA, Kepadatan, Rasio C/N, Udang windu.

The authors approach wood within the framework of object biographies and link the study of wooden artefacts with broader archaeological understandings of formation processes and environmental reconstruction.
A great wave: the Storegga tsunami and the end of Doggerland?

Published: December 2020

Around 8150 BP, the Storegga tsunami struck North-west Europe. The size of this wave has led many to assume that it had a devastating impact upon contemporaneous Mesolithic communities, including the final inundation of Doggerland, the now submerged Mesolithic North Sea landscape. Here, the authors present the first evidence of the tsunami from the southern North Sea, and suggest that traditional notions of a catastrophically destructive event may need rethinking. In providing a more nuanced interpretation by incorporating the role of local topographic variation within the study of the Storegga event, we are better placed to understand the impact of such dramatic occurrences and their larger significance in settlement studies.
Attention Interacts With Emotion to Drive Perceptual Impairment of Images in an RSVP Task
Authors: Singh Divita , Sunny Meera Mary
Published: December 2020

Emotion Induced Blindness (EIB) is characterized by an impairment in the detection of a neutral target image when it appears between 100-500ms after the presentation of an emotional image. EIB has been argued to be an early level perceptual impairment resulting from spatio-temporal competition between the neutral target and the emotional distractor. While the role of attentional processes is implied in EIB, there hasn’t been a systematic comparison between EIB and Attentional Blink (AB) concerning the locus of attentional control. That is, in most of the AB studies, participants are required to identify and report T1 while in EIB studies they are asked to ignore the emotional distractor. Hence, the differences between AB and EIB may stem from this difference in attentional control. In Expt. 1 and Expt. 2 participants were asked to report two targets in an RSVP stream and we found similar impairment in both the experiments, irrespective of the emotional nature of the target. However, in Expt. 3 and 4 where participants were required to report only one target, only the emotional distractor captured attention, leading to an impairment in target detection. Our result shows that target impairment in EIB is due to the exogenous attentional allocation to the emotional image. i.e., distractor image being emotionally salient captures attention in a bottom-up manner leading to the impairment in the less salient target.

Bone remodelling is a complex mechanism regulated by osteoclasts and osteoblasts and perturbation of this process leads to the onset of diseases, which may be characterised by altered bone erosion or formation. In this review, we will describe some bone formation-related disorders as sclerosteosis, van Buchem disease, hypophosphatasia and Camurati–Engelmann disease. In the past decades, the research focused on these rare disorders offered the opportunity to understand important pathways regulating bone formation. Thus, the identification of the molecular defects behind the etiopathology of these diseases will open the way for new therapeutic approaches applicable also to the management of more common bone diseases including osteoporosis.
COVID-19 with Cardiovascular Disease: Can It Help Predict Prognosis?

Published: December 2020

Two recent articles both found that cardiovascular disease was the major comorbidity in patients with COVID-19. Inflammation of the cardiovascular system and hypoxemia in patients with COVID-19 are the important causes of cardiovascular system dysfunction. Through detailed analyses of the cardiovascular system, clinicians may identify specific patterns of cardiovascular abnormalities. If such a model can been established, the prognosis of COVID-19 patients with cardiovascular disease may be predicted.
