Published: November 2022

The line of business cannot be separated from various responsibilities that must be fulfilled. The company is not only responsible to internal parties but also to external parties involving the environment and social (corporate social responsibility). The implementation of CSR can theoretically form a positive image and reputation from the community and shareholders for the company, this is also supported by the existence of CSR disclosures that can be submitted in the company's financial statements. The reality is that even though it is theoretically considered that way, not all companies are willing or able to carry out one of these responsibilities. The purpose of this study is to analyze how CSR disclosure and what can affect the disclosure by using one of the industrial sectors with the largest number in the capital market, namely manufacturing companies. Overall data obtained by literature study, in terms of determining the sample several criteria were used in order to obtain 112 companies and then analyzed using multiple linear regression. The results show that 112 companies used as samples disclose CSR in published financial statements, but this number is not the total number of manufacturing companies that have gone public on the capital market, so there are still many manufacturing companies that do not disclose CSR.

Estimasi nilai debit banjir rencana untuk perencanaan bangunan air, idealnya ditentukan berdasarkan analisis frekuensi menggunakan data debit terukur. Namun keberadaan data debit terukur seringkali tidak tersedia atau kalaupun ada terbatas. Sehingga diperlukan teknik untuk mendapatkan nilai banjir rancangan dari data hujan melalui metode Hidrograf Satuan Sintetik (HSS). Penelitian ini menguji kesesuaian tiga metode HSS (Nakayasu, Limantara dan ITB2) dalam menghasilkan debit banjir rancangan dan membandingkannya dengan debit rancangan dari debit terukur pada DAS yang berbentuk memanjang, yaitu DAS Sidutan dan DAS Reak. Nilai utama yang dibandingkan yaitu debit puncak, waktu mencapai puncak, dan waktu dasar dari HSS terhadap nilai dari HSO. Hasil yang diperoleh bahwa DAS Sidutan dan DAS Reak sama-sama berbentuk memanjang, memiliki panjang sungai utama yang hampir sama namun luas DAS Sidutan lebih besar dari DAS Reak. Hasil penurunan HSO rerata kedua DAS menunjukkan bahwa Qp dan Tb DAS Sidutan lebih besar dari DAS Reak, namun waktu mencapai puncak hidrograf (Tp) dicapai dalam waktu yang hampir sama. Metode HSS yang menghasilkan hidrograf satuan paling mendekati HSO berturut-turut adalah HSS Nakayasu, lalu ITB2 dan kemudian Limantara.

The Complexity of Bipartite Gaussian Boson Sampling
Authors: Grier Daniel , Brod Daniel J. , Arrazola Juan Miguel , Alonso Marcos Benicio de Andrade , Quesada Nicolás
Published: November 2022

Gaussian boson sampling is a model of photonic quantum computing that has attracted attention as a platform for building quantum devices capable of performing tasks that are out of reach for classical devices. There is therefore significant interest, from the perspective of computational complexity theory, in solidifying the mathematical foundation for the hardness of simulating these devices. We show that, under the standard Anti-Concentration and Permanent-of-Gaussians conjectures, there is no efficient classical algorithm to sample from ideal Gaussian boson sampling distributions (even approximately) unless the polynomial hierarchy collapses. The hardness proof holds in the regime where the number of modes scales quadratically with the number of photons, a setting in which hardness was widely believed to hold but that nevertheless had no definitive proof.
Crucial to the proof is a new method for programming a Gaussian boson sampling device so that the output probabilities are proportional to the permanents of submatrices of an arbitrary matrix. This technique is a generalization of Scattershot BosonSampling that we call BipartiteGBS. We also make progress towards the goal of proving hardness in the regime where there are fewer than quadratically more modes than photons (i.e., the high-collision regime) by showing that the ability to approximate permanents of matrices with repeated rows/columns confers the ability to approximate permanents of matrices with no repetitions. The reduction suffices to prove that GBS is hard in the constant-collision regime.

There has been increasing interest in culinary spices for their health benefits besides flavour. This study assessed the comparative effect of oven-drying on the chemical composition of selected leafy spices. Fresh Uziza (Piper guineense), Curry (Murraya koenigii), Nchanwu (Ocimum gratissimum), Parsley (Petroselinum crispum) and, Mint leaves (Mentha spicata) were assessed for proximate composition, then dried in an oven at 65 °C for 25 min. The dried spice leaves were analysed for their proximate composition, mineral contents, phytochemicals, antioxidants, and sensory properties. Proximate analysis showed that moisture content of fresh leafy spices reduced (8.76-10.23%) after drying (3.15 to 5.02%) while fat (1.57-2.83), protein (4.64-5.87%), fibre (1.15-2.83%) and ash (7.89-11.15%) increased after drying. Mineral contents of spices ranged from 7.15-140.05 mg/100g for sodium, 10.04-330.90 mg/100g for potassium and 12.75-305.30 mg/100g for calcium. Parsley spice leaves had the highest concentration of investigated phytochemicals, total polyphenols (43.36 mg/100g) and vitamin C (20.76%). Nchanwu leaves had the highest DPPH activity (75.66%) while Mint leaves had the highest FRAP (μmol/g) and vitamin E (29.98%). The sensory acceptability scores were high (6.95-8.00). The results reveal that oven-drying improved the concentration of nutrients and antioxidant activities and is effective in preserving leafy spices.

Comparison of 920 MHz and 2.4 GHz Near Ground Electromagnetic Wave Pathloss Propagation Model for Wireless Sensor Network in Forest Environment Application
Authors: Hakim Galang P. N. , Muwardi Rachmat , Yunita Mirna
Published: November 2022

A Wireless Sensor Network (WSN) system that uses wireless communication technologies occasionally experiences data loss when undertaking wireless data communication. This problem happens because of the WSN system being placed on top of the ground and surrounded by vegetation that adds more loss to the transmission. In order to avoid this problem, the wireless system design must meet its best performance. To build the best performing WSN system, electromagnetic wave behavior in the forest environment needs to be studied well. This paper investigates the electromagnetic wave behavior transmitted and propagated by a WSN node at less than 30 cm from the ground using a 920 MHz frequency. We have analyzed that low height (30 cm) and vegetation environments can also add more loss at about 30.96 dB to the free space pathloss model. The new 920 MHz (that adds 30.96 dB loss) model shows identical behavior to 2.4 GHz with an average difference of 12.24 dB. However, the 920 MHz model performs better, achieving an average RMSE of 1.06 compared with the 2.4 GHz model, which can only achieve an average RMSE of 4.92 compared with the 920 MHz measurement.

Applications of Clifford ratios unaffected by the local Schwarz paradox
Authors: Roselli Paolo
Published: November 2022

We show that the gradient of a strongly differentiable function at a
point is the limit of a single coordinate-free Clifford quotient between
a multi-difference pseudo-vector and a pseudo-scalar, or of a sum of
Clifford quotients between scalars (as numerators) and vectors (as
denominators), both evaluated at the vertices of a same non-degenerate
simplex contracting to that point. Such result allows to fix a issue
with a defective definition of pseudo-scalar field in Sobczyck’s
Simplicial Calculus. Then, we provide some consequences and conjectures
implied by the foregoing results.
Limited impact of chytridiomycosis on juvenile frogs in a recovered species
Authors: Hollanders Matthijs , Grogan Laura , McCallum Hamish , Brannelly Laura , Newell David
Published: November 2022

The amphibian chytrid fungus *Batrachochytrium dendrobatidis* (*Bd*) has
caused catastrophic frog declines on several continents, but disease
outcome is mediated by a number of factors. Host life stage is an
important consideration, and many studies have highlighted the
vulnerability of recently metamorphosed or juvenile frogs compared to
adults. The majority of these studies have taken place in a laboratory
setting, and there is a general paucity of longitudinal field studies
investigating the influence of life stage on disease outcome. In this
study, we assessed the effect of endemic *Bd* on juvenile *Mixophyes
fleayi* (Fleay’s barred frog) in subtropical eastern Australian
rainforest. Using photographic mark-recapture, we made 386 captures of
116 individuals and investigated the effect of *Bd* infection intensity
on the apparent mortality rates of frogs using a multievent model
correcting for infection state misclassification. We found that *Bd*
infection status nor infection intensity were not correlated with
mortality in juvenile frogs, counter to the expectation that early life
stages are more vulnerable to disease, despite high infection prevalence
(0.35, 95% HDPI [0.14, 0.52]). Additionally, we found that observed
infection prevalence and intensity were somewhat lower for juveniles
than adults. Our results indicate that in this *Bd*-recovered species,
the realised impacts of chytridiomycosis on juveniles were apparently
low, likely resulting in high recruitment contributing to population
stability. We highlight the importance of investigating factors relating
to disease outcome in a field setting and make recommendations for
future studies.
Fusion of Ensemble Technique to equilibrize the Prediction of Face Emotions using Deep CNN models for Real time images
Authors: Pandit Dipti , Jadhav Sangeeta
Published: November 2022

Humans have an uncanny ability to detect and recognise emotions, which
is being researched for use in computerization. Face emotion prediction
remains a difficult field of study in spite of wide applications due to
its subject dependency. Innovative method of using the ensemble
classifier for the real time face emotion prediction using base
classifiers as Deep CNN models is proposed in this paper. The deep
learning algorithms are used as level 1 base classifiers. The imbalance
dataset CK+ and small dataset JAFFE are enhanced synthetically by image
augmentation method. At level 2, a meta classifier that is a fusion of
majority and relative voting techniques is utilized to improve the
accuracy of individual emotions. The proposed technique’s overall
performance is evaluated and validated using randomly selected face
emotion images from the internet with improved overall accuracy. The
proposed ensemble fusion technique NCL is used for cross validation on
FER2013 dataset.
Earthen dam monitoring using passive seismic: a forward modeling study
Authors: Aguiar Guilherme Zakarewicz de , Maciel Susanne Tainá Ramalho
Published: November 2022

Internal erosion caused by infiltration and piping is the main cause of earthen dams’ failures. Traditional methods of inspection are not representative and are unable to cover the entire structure. The seismic interferometry emerges as an alternative for continuous monitoring earthen dams from the detection of variations in seismic velocities caused by water saturation. The objective of this study is the geophysical investigation of the Paranoá’s dam (Brasília, DF, Brazil) in hypothetical infiltration scenarios. To obtain a geological model that represents the expected structure, we performed an acquisition with active sources in the region and applied inversion techniques to retrieve the seismic velocities. We simulated acquisitions in a simple geological model of two horizontal layers for better understanding the behavior of the retrieved seismograms. The results show that more recording time and a wide receiver coverage improves the signal-to-noise ratio. We simulated a layer saturation by varying the velocities and noticed that the method was able to detect such variations. We noticed alterations in the reflection hyperbola asymptotes and in the first arrival time through the seismograms. The method also verified velocity changes in a more complex geological model. Our results suggest that the traffic energy is sufficient to image the dam’s structure, even not satisfying the theoretical diffuse wave field condition. Furthermore, we implemented a technique to monitor velocity variations using the semblance calculation. The method detected variations in the structure Vp in the order of 10%.

Published: November 2022

Ultramafic xenoliths and minerals present in intrusive rocks make it possible to infer the temperature and pressure of the upper mantle and lower crust, since they preserve their physical and chemical characteristics while being transported by magmatic processes. Thermal models incorporating thermo-barometric data have been developed to estimate the thermal field. Thus, the objective of this work is to use mineralogical temperature and pressure equilibrium information to estimate lithospheric thermal field in the Patagonian region bounded by latitudes 40º - 52º S and longitudes 67º - 71º W, these coordinates correspond to the Argentine provinces of Río Negro, Chubut and Santa Cruz. Experimental mineral temperature data indicate ranges of 917-1029 ºC in the Chubut province, 877-1253 ºC in the Río Negro region and 728-1196 ºC in the Santa Cruz province. The average heat flux and temperature values at the Moho depth are 40 mWm-2 and 734 ºC, respectively. Río Negro province has the highest temperature (760 ± 45 ºC) and the lowest thermal thickness value (75 ± 11 km), while Santa Cruz province has the highest heat flux (44 ± 7 mWm-2) at Moho depth, which indicates that there are possibly two plumes responsible for the deposition of xenoliths in the region: one in Río Negro province and the other in Santa Cruz.
Comparison between L2- and L1-norm and among optimization algorithms for a nonhyperbolic multiparametric approach for converted-wave and OBN data
Authors: Zuniga Nelson Ricardo Coelho Flores
Published: November 2022

As velocity analysis is an important step in seismic processing, several nonhyperbolic travel-time approximations have been proposed during the last decades, and each nonhyperbolic approximation was developed for different conditions and with different proposals. However, none of them was proposed to consider the combined effect of the nonhyperbolicity coming from layered media with large offsets, wave conversion and difference of datum between source and receiver. For this, a nonhyperbolic multiparametric travel-time approximation, which is capable of describing this combination of effects, was recently proposed. As this approximation was developed to characterize ultra-deep reservoirs, the understanding of its behavior is necessary for an offshore reservoir concerning the objective function topology complexity, as it is important for a better understanding of its behavior during the inversion procedure, and also important to determine the kind of optimization algorithm to be used. Performing the inversion procedure with different optimization algorithms and norms is proposed. The complexity analysis of the objective function is also proposed. Then, a comparison between each norm and among each algorithm concerning their accuracy and efficiency is proposed, to find which combination is the most effective to recover RMS velocity information for this kind of scenario.
Pore Pressure Estimation for Shaly Sand Formations Using Rock Physics Models For Compressional and Shear Velocities: A 1D Geomechanical Approach
Authors: Francia Renzo , Moraes Fernando Sergio de
Published: November 2022

Pore pressure estimation in sedimentary basins has been made exclusively through the compressional velocity data since the 1960s, using the normal compaction trend and lithostatic pressure profile derived from wireline logs. Considering that seismic velocity is highly dependent on petrophysical parameters such as porosity and clay volume, pore pressure estimation is commonly associated with a high degree of uncertainty due to simplistic assumptions that neglect those dependencies. To improve that, we propose two empirical velocity models based on compressional and shear rock physics relations for pore pressure prediction in shaly sand formations. These formulations extend Bowers and Doyen formulae, linking compressional and shear velocities with effective stress and petrophysical parameters. Finally, we used a non-linear multidimensional inversion approach to calibrate the proposed models and apply them in the context of a 1D geomechanics and pore pressure prediction study of an upper cretaceous overpressured shaly sand oil reservoir. The results show good agreement with pore pressure data and pressure predictions from the traditional Eaton method. The advantage of the proposed approach is its consistency throughout the entire well-log petrophysical interpretation workflow, especially concerning porosity, clay volume and saturation.
Improving seismograms’ resolution by using a phase-shrinkage filtering method
Authors: Porsani Milton José
Published: November 2022

The improvement in the temporal resolution of seismograms is usually achieved by compressing, or deconvolving, the seismic pulse. In this paper, I present a new method of filtering time series that shrinks the positive or negative polarity band of a signal while expanding its opposite polarity. The filtering method uses the complex seismic trace to compute the instantaneous phase, which is shrunk around the positions of the local maxima (or minima) values corresponding to the reflections of the original signal. It calculates the real and imaginary components afterward, thus representing the filtered signal. The method is applied trace-by-trace and promotes a significant improvement in the temporal resolution of the seismograms, revealing in greater detail the reflections and structures of the subsurface. Numerical examples with stacked seismic - 2D from the Pelotas Basin, from the mouth of the Amazon river - and, 3D - from F3Demo, illustrate the performance of the new method proposed here. The average amplitude spectra of the filtered data reveal the presence of the high and low frequency contents in the filtered results.

Many different acupuncture points and techniques have been used in the treatment of peripheral nerve injuries. It is known that alternative and complementary medicine techniques have become popular in the treatment of nerve damage in recent years. In this study, it was aimed to investigate the effectiveness of electroacupuncture in acute and chronic radial and ulnar nerve injuries. Electromyographic measurements were made to evaluate the effectiveness of electroacupuncture. In the study, the rabbits were divided into four groups namely acute nerve injury (ANI) group, chronic nerve injury (CNI) group, positive control (PC) group and negative control (NC) group. In the ANI, CNI and PC groups, damage was created on the nervus radialis and nervus ulnaris by applying pressure for 60 seconds using a hemostatic forceps under anesthesia. No damage was created in the NC group. Fifteen sessions of electroacupuncture were applied to the rabbits in the ANI, CNI, and NC groups every other day using LI-4, LI-10, LR-3, and ST-36 electroacupuncture points. Electroacupuncture was not applied to the rabbits in the PC group. Electromyographic examinations of both forelimbs of rabbits were performed during electroacupuncture applications. In the study, rabbits in the ANI group were measured at first amplitudes of 9.78 ? 1.66, and final amplitudes of 18.94 ? 1.83 (p ? 0.01). Rabbits in the CNI group were measured at first amplitudes of 11.34 ? 1.52, and final amplitudes of 16.03 ? 1.35 ( p ? 0.01). However, no statistically significant difference was found between the first and last latency values for both groups of rabbits. As a result, it was determined that electroacupuncture is an effective treatment method for both acute and chronic nerve injuries, as well as being more effective in acute cases than in chronic cases.
Reescribiendo el masoquismo en el siglo XXI: La Venus de las pieles (2014) de David Serrano
Authors: Godón Nuria
Published: November 2022

Este estudio plantea un recorrido teórico del masoquismo en relación con la cuestión de género para ofrecer mediante la adaptación teatral de La Venus de las pieles (2014) de David Serrano una nueva interpretación del masoquismo en la España del siglo XXI. La adaptación de Serrano parte del texto teatral de David Ivés (2010) basada en la novela La Venus de las pieles (1870) de Leopold von Sacher-Masoch. La pieza brinda un juego metateatral que se abre con un casting en busca de la actriz que pueda desempeñar el papel de dominatrix que La Venus de las pieles requiere. La obra explota la confluencia de diversos sentidos del masoquismo mediante el cuestionamiento de sus distintas interpretaciones y representaciones a lo largo de la historia. Dentro del proceso de lucha por la dirección teatral, en la que los actores se intercambian los roles genéricos para mostrar una adecuada actuación de ellos, examino la articulación de los mecanismos de poder del masoquismo en relación con los de la construcción genérica exhibidos a lo largo de la pieza. Mi análisis me lleva a formular el masoquismo como herramienta de liberación genérica y a exponer la distribución de roles como acto performativo. Asimismo, atiendo al poder soterrado del masoquismo que expone cómo el dominio ejercido por las mujeres de hoy día sigue dirigido de manera velada y sutil por la imaginación masculina y por el poder hegemónico. Vinculo estos mecanismos de poder a una vieja escritura del masoquismo y apunto a cómo la obra presenta la necesidad de una dirección y autoría femenina en torno al masoquismo que rompa con los encadenamientos de roles genéricos a los que todavía la sociedad española del presente está sometida.
(Post)Feminist Maternal Chronicles and Their Discontents
Authors: Bettaglio Marina
Published: November 2022

This essay reads the conflict, ambivalence and guilt that pervade what I call "maternal chronicles"—a heterogenous set of autobiographical texts centering on the experience of mothering—as symptomatic of the postfeminist turn in Spanish society. While in literature, maternal narratives continue to be scarce (Freixas 2012), the last ten years have witnessed the emergence of new narrative forms, ranging from blogs to diaries to comics, that express their authors’ ambivalent feelings towards this "sacred" institution (Lucía Extebarria, Care Santos, Isabel García Zarza, Yolanda Saenz de Tejada, Inmaculada Gilaberte, Gabriela Wiener, Gemma Sesar etc.). As Spain continues to experience one of the lowest birth rates in the world, popular culture presents glamorous maternal images that reflect the resurfacing of pro-natalist discourses aiming "to put motherhood squarely back at the heart of women’s lives" (Badinter 1). While the popular media contribute to the creation of a new "motherhood mystique" (to borrow Susan Douglas and Meredith Michaels’s definition), maternal chronicles often express frustration with unattainable maternal myths, while stopping short of invalidating them completely. Reading maternal memoirs vis-à-vis popular culture, this essay argues that the articulation of maternal subjectivities in contemporary Spanish culture is symptomatic of a paradoxical situation, in which motherhood is celebrated as a source of women’s fulfillment in a society characterized by deeply antimaternal structures with high unemployment rate, low gender equality in the workplace, uneven distribution of domestic chores, and lack of state support for working mothers.

The interpretation of sensor system data is critical for monitoring industrial welding processes and providing reliable information about the condition of the weld seam. Previous investigations have shown that acoustic emissions of frequencies up to several kilohertz during laser beam welding are parameter-dependent and contain valuable information about the process. A microphone was employed to record the acoustic emissions produced when performing deep penetration laser beam welding of copper. Experiments were conducted in which the laser power and the feed rate were varied so as to obtain acoustic data comprising frequencies of up to 1 MHz. The signals were preprocessed and features were extracted using Fourier and wavelet analysis as well as speech analysis techniques. The relationship between the features extracted from the acoustic signal and the weld depth was modeled using Gaussian process regression. The results showed that acoustic emissions during laser beam welding can be used to predict the weld depth without having to rely on process parameters, i.e., the laser power and the feed rate. Overall, 17 features were extracted from acoustic signals, with the zero-crossing rate displaying the highest significance for determining the weld depth. These investigations open up new possibilities of robust quality assurance for laser beam welding applications based on acoustic emissions.
