) on–off-keying (OOK) signal by using a high-bandwidth (BW) silicon photonic (SiP) transmitter with the aid of digital signal processing (DSP). In this transmitter, a four-channel SiP modulator chip is co-packaged with a four-channel driver chip, with a measured 3 dB BW of 40 GHz. DSP is applied in both the transmitter and receiver sides for pre-/post-compensation and bit error rate (BER) calculation. Back-to-back (B2B) BERs of the PAM-4 signal and OOK signal are first measured for each channel of the transmitter with respect to a variety of data rates. Similar BER performance of four channels shows good uniformity of the transmitter between different channels. The BER penalty of the PAM-4 and OOK signals for 500 m and 1 km standard single-mode fiber (SSMF) transmission is then experimentally tested by using one channel of the transmitter. For a 200 Gbit/s PAM-4 signal, the BER is below the hard-decision forward error correction (HD-FEC) threshold for B2B and below the soft-decision FEC (SD-FEC) threshold after 1 km transmission. For a 120 Gbit/s OOK signal, the BER is below SD-FEC threshold for B2B. After 500 m and 1 km transmission, the data rate of the OOK signal shrinks to 119 Gbit/s and 118 Gbit/s with the SD-FEC threshold, respectively. Finally, the 800 Gbit/s PAM-4 signal with 1 km transmission is achieved with the BER of all four channels below the SD-FEC threshold.
Note 57: Hospitable approaches to community music scholarship1
Authors: Higgins Lee
Published: September 2020

The purpose of this article is to evoke an approach to scholarship that is resonant with community music’s ethos and practice. After contextualizing questions that have driven my work, I engage with a ‘philosophical critique’ of community music, published in 2016, through one of its endnotes and, in so doing, reveal why the text is problematic and ‘out of step’ with contemporary thinking concerning understandings of community music. Following this, I develop some ideas associated with community music as an act of hospitality and, in so doing, provide a potential lens for critique rather than a criticism. In conclusion, I advocate for future scholars and researchers to have a sensitivity and understanding of the practices and the issues that face those who are engaged in community music in order to generate a conducive environment through which powerful critique might be made.

Authors: Yashchenko Elena Fedorovna , Shchelokova Ekaterina Galiulovna , Lazorak Olga Vasilievna
Published: September 2020

Internationalization is one of the current directions of education development. Specially organized university work and identification of features of self-actualization in foreign students will contribute to the development of more effective programs of psychological support during socio-psychological adaptation. Aim. The paper aims to identify the personal features of foreign students with a high and low level of self-actualization during socio-psychological adaptation. Materials and methods. 52 foreign students aged from 18 to 32 years studying in London were examined. The study was based on the following methods: Yankovsky questionnaire of adaptation to a new socio-cultural environment, the Rogers and Diamond technique of diagnosis of socio-psychological adaptation, the Jones and Crandall Short Index of self-actualization, etc. The results for interpretation were obtained by statistical analysis (Mann – Whitney criterion) and correlation analysis (Spearman rank correlation coefficient) using SPSS 22.0 statistical software package. Results. Foreign students with a high level of self-actualization experience subjective well-being, and social surrounding is significant to them; however, subjective well-being is reduced when it is impossible to preserve individuality and choose a conformal type of adaptation. Foreign students with a low level of self-actualization have a subjective disadvantage that lessens when maintaining their individuality, pragmatic orientation, the acceptance of others, and self-actualization. Nevertheless, foreign students with a low level of self-actualization demonstrated a correlation between self-actualization and the interactive type of adaptation. Conclusion. The prospects for self-actualization of foreign students with a high and low level of self-actualization and the specifics of their socio-psychological adaptation have been studied.
Tytuł profesora w pierwszych latach przemian ustrojowych Rzeczypospolitej Polskiej
Authors: Wojtczak Krystyna
Published: September 2020

The political changes initiated in 1989 affected many sectors of the state’s activity, including higher education and science. In 1990, the Sejm passed two new Laws – on Higher Education, and on Academic Degrees and Title. The former placed greater emphasis than before on the freedom to conduct scientific research. With the second act, it finally abandoned the possibility provided for by the 1965 solutions of granting two different titles of professor, i.e., associate professor and full professor, by introducing one academic title – “professor”. For the purposes of evaluating and establishing the significance of the solutions adopted by the 1990 Law, this article presents the procedure and conditions for awarding the titles of professor provided for in the 1965 Law in the wording in force prior to its repeal in 1990, as well as those introduced set out in the 2003 Law and in force until its amendment in 2011. The replacement of the two titles of professor with a single academic title did not limit the range of proposals for changes introduced at that time. In the article, particular attention is devoted to these. The main trend in research comes down to: (1) how the degree and scope of regulations adopted in 1990 differed from earlier solutions, and (2) whether, in the context of the 2003 Law they were sufficient and served the quality of academic advancements well. It is only by basing research on previous findings in this respect that conclusions could be drawn as to the legal meaning and significance of conferring the title of professor in the years 1990–2011. This approach in achieving the purpose of the discussions was also important foranother reason. It made it possible to emphasize the changes in terms of awarding the title of professor from the solutions in force during the Polish People’s Republic to the norms adopted in the initial years of the political transformation, as well as to the new regulations introduced in the more strongly established Republic of Poland. These were not the same solutions, and the Act of 1990 placed them in thegroup of liberal solutions.
Lex deweloper – analiza porównawcza projektu pierwotnego specustawy mieszkaniowej z ostatecznie uchwaloną ustawą
Authors: Pawłowski Sławomir
Published: September 2020

The study is a comparative analysis of the original draft Act on facilitating the preparation and implementation of housing and associated investments, i.e. from March 2018 with the text finally adopted on 5 July 2018. Making such comparative analysis is justified by significant changes that occurred in the original concept of the act intended to encourage private investors to significantly accelerate the fulfilment of housing needs in Poland. Being similar to special public investment acts, the act initially established the voivode as the authority competent to take the final decision in the first instance. In addition, this decision was to take the form of an integrated decision, in which not only permission for the location of a residential investment would be issued, but also, in a simplified mode, consent for cutting down trees in cities would be obtained. These and other solutions were criticized during public consultations, and these opinions were taken into account. This elaboration will present the thesis that the original shape of the Act on facilitating the preparation and implementation of housing and associated investments would unjustifiably affect the planning authority of the commune, whose position would be marginalized. In addition, there is also a discussion of the legal nature of the location decision, which in the adopted act took the form of a commune council resolution. This part of the study will first analyze the legal nature of municipal council resolutions in general, including whether they will always take the form of general and abstract acts. This will be the starting point for assessing whether this resolution will constitute a general act of applying the law, i.e. a general administrative act.
Cross-chain deals and adversarial commerce
Authors: Herlihy Maurice , Liskov Barbara , Shrira Liuba
Published: September 2020

Modern distributed data management systems face a new challenge: how can autonomous, mutually-distrusting parties cooperate safely and effectively? Addressing this challenge brings up questions familiar from classical distributed systems: how to combine multiple steps into a single atomic action, how to recover from failures, and how to synchronize concurrent access to data. Nevertheless, each of these issues requires rethinking when participants are autonomous and potentially adversarial.

We propose the notion of a
cross-chain deal
, a new way to structure complex distributed computations that manage assets in an adversarial setting. Deals are inspired by classical atomic transactions, but are necessarily different, in important ways, to accommodate the decentralized and untrusting nature of the exchange. We describe novel safety and liveness properties, along with two alternative protocols for implementing cross-chain deals in a system of independent blockchain ledgers. One protocol, based on synchronous communication, is fully decentralized, while the other, based on semi-synchronous communication, requires a globally shared ledger.
Interleaved multi-vectorizing
Authors: Fang Zhuhe , Zheng Beilei , Weng Chuliang
Published: September 2020

SIMD is an instruction set in mainstream processors, which provides the data level parallelism to accelerate the performance of applications. However, its advantages diminish when applications suffer from heavy cache misses. To eliminate cache misses in SIMD vectorization, we present interleaved multi-vectorizing (IMV) in this paper. It interleaves multiple execution instances of vectorized code to hide memory access latency with more computation. We also propose residual vectorized states to solve the control flow divergence in vectorization. IMV can make full use of the data parallelism in SIMD and the memory level parallelism through prefetching. It reduces cache misses, branch misses and computation overhead to significantly speed up the performance of pointer-chasing applications, and it can be applied to executing entire query pipelines. As experimental results show, IMV achieves up to 4.23X and 3.17X better performance compared with the pure scalar implementation and the pure SIMD vectorization, respectively.
A unified optimization algorithm for solving "regret-minimizing representative" problems
Authors: Shetiya Suraj , Asudeh Abolfazl , Ahmed Sadia , Das Gautam
Published: September 2020

Given a database with numeric attributes, it is often of interest to rank the tuples according to linear scoring functions. For a scoring function and a subset of tuples, the
regret
of the subset is defined as the (relative) difference in scores between the top-1 tuple of the subset and the top-1 tuple of the entire database. Finding the
regret-ratio minimizing set
(RRMS), i.e., the subset of a required size
k
that minimizes the maximum regret-ratio across all possible ranking functions, has been a well-studied problem in recent years. This problem is known to be NP-complete and there are several approximation algorithms for it. Other NP-complete variants have also been investigated, e.g., finding the set of size
k
that minimizes the
average regret ratio
over all linear functions. Prior work have designed customized algorithms for different variants of the problem, and are unlikely to easily generalize to other variants.

In this paper we take a different path towards tackling these problems. In contrast to the prior, we propose a unified algorithm for solving different problem variants. Unification is done by localizing the customization to the design of variant-specific subroutines or "oracles" that are called by our algorithm. Our unified algorithm takes inspiration from the seemingly unrelated problem of
clustering
from data mining, and the corresponding k-medoid algorithm. We make several innovative contributions in designing our algorithm, including various techniques such as linear programming, edge sampling in graphs, volume estimation of multi-dimensional convex polytopes, and several others. We provide rigorous theoretical analysis, as well as substantial experimental evaluations over real and synthetic data sets to demonstrate the practical feasibility of our approach.
Efficient progressive minimum k-core search

Published: September 2020

As one of the most representative cohesive subgraph models,k-core model has recently received significant attention in the literature. In this paper, we investigate the problem of the minimumk-core search: given a graphG, an integerkand a set of query verticesQ= {q}, we aim to find the smallestk-core subgraph containing every query vertexqϵQ.It has been shown that this problem is NP-hard with a huge search space, and it is very challenging to find the optimal solution. There are several heuristic algorithms for this problem, but they rely on simple scoring functions and there is no guarantee as to the size of the resulting subgraph, compared with the optimal solution. Our empirical study also indicates that the size of their resulting subgraphs may be large in practice. In this paper, we develop an effective and efficient progressive algorithm, namelyPSA, to provide a good trade-off between the quality of the result and the search time. Novel lower and upper bound techniques for the minimumk-core search are designed. Our extensive experiments on 12 real-life graphs demonstrate the effectiveness and efficiency of the new techniques.
“A Notion of the True System of the World”: Berkeley and his Use of Plato in Siris
Authors: Larsen Peter D.
Published: September 2020

This paper considers Berkeley’s use of Plato in Siris. Berkeley’s engagement with ancient thinkers in Siris has been a source of puzzlement for many readers. In this paper I focus on Siris § 266. In particular, I consider why Berkeley says of the Platonists that they “distinguished the primary qualities in bodies from the secondary” and why, given his own well-known misgivings about the distinction, he characterizes this as part of a “notion of the true system of the world.” I argue that in Siris Berkeley accepts a distinctive form of corpuscularianism, and that he thinks a distinction between primary and secondary qualities follows from this. I further argue that in § 266, and elsewhere in Siris, Berkeley engages in a careful reading of Plato’s Timaeus, which he uses to bolster his defense of the compatibility between corpuscularianism and his immaterialist idealism.

On the Choice of Liability Rules
Authors: Kundu Rajendra P. , Pal Debabrata
Published: September 2020

Legal assignment of liabilities for losses arising out of interactions involving negative externalities usually depend on which of the interacting parties are negligent and which are not. It has been established in the literature that, if negligence is defined as failure to take some cost-justified precaution then there is no liability rule which can always lead to an efficient outcome. The objective of this paper is to try and understand if it is still possible to make pairwise comparisons between rules on the basis of efficiency and to use such a method to explain/evaluate choices from a given set of rules. We focus on a set of five of the most widely analyzed rules (no liability, strict liability, negligence, negligence with the defense of contributory negligence and strict liability with the defense of contributory negligence), and use a binary relation according to which a rule in the set is considered to be at least as efficient as another if and only if the set of applications for which it is inefficient is a subset of the set of applications for which the other one is inefficient. We show that, with respect to the above mentioned relation, pairwise comparisons between rules in this set fail. The paper, thus, demonstrates that an efficiency based explanation for any choice from these five rules is not consistent with the notion of negligence defined as failure to take some cost-justified precaution.
Pinless friction stir spot welding of aluminium alloy with copper interlayer
Authors: Abed Balsam H. , Salih Omar S. , Sowoud Khalid M.
Published: September 2020

Spot welding joints of Al-Mg-Si alloy (AA6061-T6) were produced with and without the addition of copper interlayer using pinless friction stir spot welding (P-FSSW). To investigate the effects of welding parameters on the metallurgical and mechanical properties of the weldment, various tool plunge depth and dwell time were used. Optical microscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy (EDS) have been used for microstructural characterisation.Meanwhile, the mechanical characterisation of the welded joints was evaluated by tensile-shear test. The experimental results showed that a larger bonding area and sound joint were achieved with the addition of Cu interlayer due to the improvement in thermal distribution. Also, an alloying reaction took place between the aluminium substrate and Cu interlayer during P-FSSW, forming intermetallic compounds layer in the interface through the diffusion process. The increasing of dwell time and plunge depth to some extent were beneficial to the formation of the joint and diffusion process, and thus increasing the tensile-shear load of the joints. The observed fracture mode of the joint was either completely shear off in the interface or complete nugget pullout.
Multilingualism and internationalisation in doctoral education: Discourse, positioning and agency
Authors: Hofmann Stephanie
Published: September 2020

Despite the growing linguistic and cultural diversity in higher education and research, little is known about how students and researchers use their plurilingual repertoire for writing and publishing. In particular, the roles of the national language(s) and the linguistic repertoire(s) vis-à-vis English as the lingua franca for academic writing and publishing have not been closely examined. This paper explores how doctoral researchers in Luxembourg position themselves in relation to macro-level discourses about language and academic success within their complex lingua-cultural and socio-economic setting. By analysing interview transcripts of two multilingual doctoral researchers from Russia and Germany, I show how in spite of their similar starting situations they negotiate agency to varying degrees. In particular, the prevalence of English and the pressure to publish in international journals seem to make them struggle to use their full linguistic repertoire in writing their theses.
Effect of radiative heat loss on thermal diffusivity evaluated using normalized logarithmic method in laser flash technique
Authors: Nishi Tsuyoshi , Azuma Naoyoshi , Ohta Hiromichi
Published: September 2020

The laser flash technique is a standard method to measure the thermal diffusivity of solid samples especially at high temperatures. To understand the reliability of thermal diffusivity evaluation at high temperature for solid samples with low-thermal-diffusivity values, we analyzed the effect of radiative heat loss using the logarithmic method. The results revealed that when the Biot number was 0.1, the deviation from the input thermal diffusivity value was approximately −1.6%. In addition, when an aluminum silicate (AS) sample was heated to 1,273 K, the maximum deviation was approximately −0.35%. In contrast, the difference between the input value and the thermal diffusivity evaluated by the halftime method when AS was heated to 1,273 K was approximately 2.38%. Thus, since the effect of radiative heat loss was found to be negligible, it is concluded that the normalized logarithmic method should be very useful for the thermal diffusivity analysis of low-thermal-diffusivity solid samples at high temperature.
Oxidizability characterization of slag system on the thermodynamic model of superalloy desulfurization
Authors: Li Wanming , Sun Yulei , Wu Shaopeng , Zang Ximin
Published: September 2020

The oxidizability characterization method of slag system has a decisive influence on the accuracy of the desulfurization model. By carrying out the balance experiments of melting system composed of CaF2–CaO–Al2O3–SiO2–TiO2–MgO–FeO slag system and Inconel 718 superalloy, the influence of Al2O3 and FeO on desulfurization distribution ratio at 1,773 K was studied. Based on the ion and molecule coexistence theory in slag, the effects of three oxidizability characterization methods, [Fe]–[O] balance, [Al]–[O] balance, and [Fe]–[Al]–[O] balance, on the accuracy of desulfurization thermodynamic model were studied. The results show that the effect of FeO on desulfurization distribution ratio is more significant than that of Al2O3 when the FeO content in slag is greater than 0.014%. When the FeO content in the slag is less than 0.014%, the effect of Al2O3 on the slag oxidizability will be greater than that of FeO. The calculated value of [Fe]–[Al]–[O] balance model is closer to the experimental-measured value compared to [Fe]–[O] balance model and [Al]–[O] balance model alone at 1,923 K.
The co-combustion and pollutant emission characteristics of the three kinds of waste ion exchange resins and coal
Authors: Zhang Xiaobin , Liu Meng , Gao Xin
Published: September 2020

The co-combustion of waste ion exchange resin (WIER) and coal in a coal-fired incineration plant is an economical and feasible treatment method. The effects of the amount of WIER on the co-combustion and pollutant emission characteristics are investigated in a thermogravimetric infrared analyzer and tube furnace respectively. Results show that the weight loss rate of WIER combustion is significantly higher than that of coal within 400 °C, and the ignition temperature of the mixture improves with the increased addition of WIERs. The release of sulfur dioxide during the combustion of waste anionic exchange resin (WAER) and waste cationic exchange resin (WCER) mainly occurs at 320–440 °C. The highest concentration of HCl in the combustion of waste mixed exchange resin (WMER) is mainly released at approximately 350 °C. However, the addition of WIERs causes a sharp decrease in the emission of NOx. Moreover, the sulfur and chlorine in the WIERs are respectively released in gaseous forms of SO2 and HCl and do not exist in the fly ash as salt compounds.
Effect of different drying methods on the physicochemical properties and phycobiliprotein structure of Porphyra haitanensis
Authors: Xu Dalun , Sun Nan , Xuan Shifen , Wang Chen , Huang Tao , Li Chao , Zhang Jinjie , Yang Wenge
Published: September 2020

This study explored the effects of four drying methods, namely vacuum freeze-drying (VFD), hot-air drying (HD), microwave drying (MD) and shade drying (SD) on the sensory quality, amino acids composition, phycobiliproteins structure and rehydration rate of Porphyra haitanensis. It showed that VFD dried P. haitanensis had the highest protein (35.44 ± 0.87%), polysaccharide (18.91 ± 0.64%), umami amino acids (484.67 ± 5.03 mg/100 g, dry weight) and essential amino acids (9.89 ± 0.27 g/100 g, dry weight) than another three dried products. Drying affected secondary structure of phycobiliproteins, and the phycobiliproteins from VFD laver contained the most α-helix structure and the least random coil. In addition, VFD processed laver was rich in water-soluble polysaccharides and hydrophilic amino acids, which resulted in its quick rehydration and high-water absorption capacity. The results showed that VFD was suitable for producing high-quality P. haitanensis with excellent flavor and high contents of nutritional compounds.

In this paper, we consider a seventh-order generalized Korteweg–de Vries (GKdV) equation and study the boundary stability results concerning the inverse problem of recovering a space-dependent source term.
We establish a new boundary Carleman estimate for the seventh-order linear operator with the Dirichlet–Neumann type boundary conditions.
Using this crucial estimate along with regularity result of the nonlinear GKdV equation, we establish a Lipschitz stability estimate of GKdV equation.

In a note from around 1769, Kant raised the question of why synthetic judgments cannot become analytic. He did not, however, suggest an answer. In a 1789 essay, J. G. E. Maaß published an exemplary criticism of this division of judgments by pointing out that it was relative. Kant entrusted one of his disciples, J. Schultz, with the task of defending the absolute nature of the distinction. Schultz responded in 1790, using annotations by Kant himself. Moreover, in Schultz’s 1789 Examination, there are some remarks which anticipate certain misrepresentations Maaß would continue to make in his new essay in response to Schultz in 1791. Focusing on the reconstruction of this debate, the paper seeks to identify how Kant justified the fact that his division of judgments was not arbitrary, even if the justification was never explicit.

MiR-1225-5p acts as tumor suppressor in glioblastoma via targeting FNDC3B

Published: September 2020

This study attempted to research the molecular mechanism underlying the inhibitory role of miR-1225-5p in the malignant progression of glioblastoma. Bioinformatics analyses based on the gene expression omnibus (GEO) and Chinese glioma genome atlas (CGGA) databases showed that miR-1225-5p, as a favorable prognostic factor, was expressed at low levels in glioblastoma, and its expression was also related to WHO grade and age. The subsequent CCK-8 assay indicated that miR-1225-5p might prevent the malignant progression of glioblastoma, which was represented by that miR-1225-5p mimic reduced the viability of glioblastoma cells. Then, we predicted that FNDC3B might be a potential target gene of miR-1225-5p, and it was negatively correlated with the level of miR-1225-5p, which were confirmed by dual-luciferase reporter assay, qRT-PCR and western blot assays. Moreover, based on the analyses of the cancer genome atlas (TCGA), Oncomine and CGGA databases, FNDC3B was enriched in glioblastoma and high expression of FNDC3B led to poor prognosis. Finally, CCK8 and transwell experiments showed that the ability of miR-1225-5p to inhibit glioblastoma cell viability, invasion and migration was at least partially achieved by targeting FNDC3B. In general, these results revealed that the miR-1225-5p/FNDC3B axis contributes to inhibiting the malignant phenotype of glioblastoma cells, which lays a foundation for molecular diagnosis and treatment of glioblastoma.
Leading a Double Life: Statues and Pieces of Clay
Authors: Biro John
Published: September 2020

Some philosophers think that two distinct things can occupy exactly the same region of space, as with a statue and a piece of clay. Others think that the statue and the piece of clay are identical, but not necessarily so. I argue that Alan Gibbard’s well-known story of Goliath and Lumpl does not support either of these claims. Not the first, as there is independent reason to think that it cannot be true. Not the second, because there is no need to invoke the dubiously intelligible notion of contingent identity to account for the facts of the story.
Process modifications to obtain a prehydrolysis kraft dissolving pulp with low limiting pulp viscosity
Authors: Brännvall Elisabet , Walter Karin
Published: September 2020

Cellulose can be directly dissolved in cold alkali without derivatization. However, this requires low cellulose molecular weight, i. e. low pulp viscosity, preferably below 300 mL g−1. This can be achieved by for example acid or enzymatic hydrolysis of the dissolving pulp. However, it would be beneficial to manufacture pulp with sufficiently low viscosity without an additional treatment stage prior to dissolution. Unit processes in pulping can be operated in such a way as to reduce the molecular weight of cellulose. The approach of the study was to modify the conditions in unit pulping processes in order to obtain a low pulp viscosity of fully bleached prehydrolysis kraft pulp. A high charge of alkali in the oxygen delignification reduced the cellulose molecular weight significantly. Increased temperature, 120 °C compared to 98 °C, had also a significant effect on viscosity. By performing peroxide bleaching at acidic pH, the viscosity could be sufficiently reduced even when oxygen delignification was performed at lower temperature. However, for high brightness, a chlorine dioxide stage is needed.
A new classification method of nanotechnology for design integration in biomaterials
Authors: Zhang Li , Liu Tao , Xie Yinhong , Zeng Zheng , Chen Junying
Published: September 2020

Currently, advanced biomaterial design solutions often have more than two kinds of nanotechnology design strategies, but there is no suitable classification to describe these designs systematically. Based on the material design ideas and the modes of implementing functions, this article exemplifies and proposes a new nanotechnology classification that includes physical properties, the chemical reactions that respond to the microenvironment and bio-inspired incorporation. If two or more nanotechnology designs in the same classification are to be integrated into the same biological material, it is necessary to analyze the integration conflict between the designs. With the development of big data, this classification method may help researchers and artificial intelligence to realize automated integration of multiple designs and provide new material nanotechnology design integration solutions.
Food choice motivations and perception of a healthy diet in a developing Mediterranean country
Authors: Boustani Nada Mallah , Guiné Raquel P. F.
Published: September 2020

This study investigated the Lebanese consumers’ knowledge about healthy food perception and their food motivations according to gender and also to environmental, social, and health behaviors. The survey consisted of a longitudinal study undertaken on a sample of 450 participants from which only 410 questionnaires were considered to be valid. For the analysis of the data, basic descriptive statistics were used, complemented with statistical tests (Student t-test for comparisons between two groups and ANOVA for comparisons between three or more groups). Finally, analyses were done to evaluate the importance of healthy food perception among these people, and the possible sociodemographic variables are as follows: age group, level of education, gender, and living environment. The results allowed identifying which types of factors mostly influence people's food choices. They revealed that both the economic and availability motivations (mean scores 2.83 and 2.98 for female and male participants, respectively) and the social and cultural motivations (mean scores 2.90 and 3.09) have less impact on the perception of a healthy diet than the healthy motivations (mean scores 3.48 and 3.29) and the environmental and political motivations (mean scores 3.35 and 3.43), this last being also the highest expression and without statistical gender differences. This work is relevant because it highlights the food motivation factors that influence people’s perception about a healthy diet in a developing country, facing social and economic crisis in addition to many gender inequalities, yet having the highest education levels in the region in addition to its multiethnical diversity and religiosity.
Senseless Pain in the Phenomenology of Religious Experience
Authors: Salim Emil
Published: September 2020

There are three models of pain in the phenomenology of religious experience. The first model suggests that pain is instrumental to attaining the desired religious experience. The second model proposes that pain is constitutive of the desired religious experience. The third model, which is a model of senseless pain in religious experience, is underdeveloped. I provide an exposition of this model in this article. I also give four arguments for the necessity of affirming senseless pain in the phenomenology of religious experience. First, affirming senseless pain in religious experience provides a way to describe the process of purpose attribution to pain qua a sensation or a feeling. Second, such an affirmation also provides a way for describing the meaning formation in religious experience through interpreting pain qua symbol. Third, the affirmation is also necessary to maintain continuity between mundane and religious experiences. There are instances of senseless pain in the literature on tragedy, chronic pain, and torture. Maintaining continuity between ordinary and religious experiences via the notion of senseless pain opens the possibility of developing mysticism in everyday life. Lastly, the presence of the unknown in senseless pain makes room for mystery in religious experience.
The Social Sciences, Pastoral Theology, and Pastoral Work: Understanding the Underutilization of Sociology in Catholic Pastoral Ministry
Authors: Ballano Vivencio O.
Published: September 2020

Applying sociological imagination and theological perspectives and using some secondary literature that focus on the American pastoral experience, this article explains why sociology and the social sciences are underutilized in the pastoral ministry of Catholic priests despite the Catholic Church’s openness to human sciences’ contributions to evangelization after the Second Vatican Council. In particular, it examines how the (i) uneasy alliance between Catholic theology and sociology, (ii) overemphasis on the invisible and theological dimension of the Church in current ecclesiologies, (iii) highly philosophical and theological clerical education which sidelines the empirical sciences in clerical pastoral work, and (iv) dominance of the individualist approaches of clinical psychology in pastoral theology have greatly contributed to the neglect of sociological inquiries and perspectives in clerical formation and pastoral ministry. It also argues that a genuine pastoral care must be based on a holistic and empirical assessment of the pastoral needs of parishioners by priests using sociology and the social sciences before it prescribes a plan of action for pastoral care to accurately inculturate the Christian message in today’s technological culture.

This article studies dark, bright, trigonometric and rational optical soliton solutions to the perturbed nonlinear Schrödinger–Hirota equation (PNLSHE). Hence, we have examined two cases: first, restrictions have been done to the third-order (TOD) (γ) as constraint relation, and the coupling coefficients (σ) is obtained as well as the velocity of the soliton by adopting the traveling wave hypothesis. Second, the TOD and the coupling coefficients are non-zero value, sending back to the PNLSHE, which has been studied in refs. [4,10,16] recently. By employing two relevant integration technics such as the auxiliary equation and the modified auxiliary equation method, miscellaneous optical solitary wave is obtianed, which is in agreement with the outcomes collected by the previous studies [4,16]. These results help in obtaining nonlinear optical fibers in the future.
