From Euclid to corner sums - a trail of telescoping tricks
Authors: Patrício Pedro , Hartwig Robert
Published: February 2022

Euclid?s algorithm is extended to binomials, geometric sums and corner sums.
Two-sided non-commuting, non-constant linear difference equations will be
solved, and the solution is applied to corner sums, thereby presenting an
explicit formula for the generator of the bi-module spanned by the two
starting corner sums.
On D-invariant points and local Taylor interpolation on algebraic hypersurfaces in RN
Authors: van Manh , Van Trao , Tung Phan , Cuong Le
Published: February 2022

We give the definition of D-invariant points on an irreducible algebraic
hypersurface V in RN. We show that every regular point on irreducible
quadratic hypersurface in RN is D-invariant. We prove that the local Taylor
interpolation projector at a regular point a 2 V is an ideal projector if
and only if a is D-invariant.
Approximation by associated GBS operators of Szász-Mirakjan type operators
Authors: Yadav Rishikesh , Meher Ramakanta , Mishra Vishnu
Published: February 2022

In this article, the approximation properties of bivariate Sz?sz-Mirakjan
type operators are studied for the function of two variables and rate of
convergence of the bivariate operators is determined in terms of total and
partial modulus of continuity. An associated GBS (Generalized Boolean
Sum)-form of the bivariate Sz?sz-Mirakjan type operators is considered for
the function of two variables to find an approximation of B-continuous and
B-differentiable function in the B?gel?s space. Further, the degree of
approximation of the GBS type operators is found in terms of mixed modulus
of smoothness and functions belonging to the Lipschitz class as well as a
pioneering result is obtained in terms of Peetre K-functional. Finally, the
rate of convergence of the bivariate Sz?sz-Mirakjan type operators and the
associated GBS type operators are examined through graphical representation
for the finite and infinite sum which shows that the rate of convergence of
the associated GBS type operators is better than the bivariate
Sz?sz-Mirakjan type operators and also a comparison is taken place for the
bivariate operators with bivariate Kantorovich operators.
BEWARE OF SCHOOLS BEARING GIFTS
Authors: Táíwò Olúfẹ́mi
Published: February 2022

Recent publication How Propaganda Works uses flawed ideologies to explain how propaganda works. I introduce the system of miseducation as an alternative, adapted from Carter G. Woodson’s The Mis-Education of the Negro. Miseducation explains instances of propaganda considered in the book but also another kind altogether, which I term Trojan horse propaganda. I consider the possibility that flawed social structures can themselves exert propagandistic effects, independent of any particular pattern of doxastic uptake by the individuals in that society. If so, this would suggest moving from analyses of how propaganda affects individuals’ beliefs and toward analyses of propaganda’s practical effects, and would count in favor of activist approaches that make strategic use of sites of epistemic power.
AN EXISTENTIALIST ANALYSIS OF “STAND YOUR GROUND” LAWS
Authors: Engels Kimberly
Published: February 2022

Stand your ground laws (SYG) allow an individual to use deadly force against a perceived attacker anywhere that he or she has a legal right to be, without the requirement to attempt retreat before using deadly force. This article offers an analysis of SYG laws through a Sartrean existentialist lens. Drawing off existing empirical research and case examples, I make three claims: First, SYG laws have existential import to the extent that they influence individuals’ beliefs, behavior, and judgments. Second, this existential import makes individuals more likely to perceive situations as threatening and find reasons to be afraid. Third, the phenomenological experience of negative emotions such as fear and anger affects our ability to make careful and reasoned judgments regarding the amount of threat we face. I build my case for these three claims using Sartre’s concept of fundamental project, or the image of self used to organize one’s existential possibilities. I also use Sartre’s phenomenological account of emotion and Robert Solomon’s account of emotion, which has Sartrean roots. I argue that, based on my analysis, the right to use self-defense should include the duty to retreat when possible.
POLICING, PROTEST, AND RIGHTS
Authors: Smith William
Published: February 2022

Protest policing is increasingly characterized by an escalation in the use of preventive measures, reflected in the global diffusion of a cluster of tactics that are geared toward enhancing police control over protest. This paper presents an interpretation of the right to protest that includes a moral claim against such efforts at prevention, while also envisaging a number of circumstances where such a claim might be legitimately overridden. It goes on to contend that, even in such circumstances, the preventive tactics employed by police must satisfy stringent tests of proportionality, liability, and necessity. The paper concludes by calling for a return to a reformulated version of the so-called “negotiated management” approach that emerged during the 1980s and 1990s.
FLIP-FLOPPING IN A REPRESENTATIVE DEMOCRACY
Authors: Sonderholm Jorn
Published: February 2022

This paper addresses an important question in normative political theory—Main Question: In a representative democracy, can a member of a legislature legitimately flip-flop and vote in accordance with the majority view on Issue when she—prior to getting knowledge, through a referendum result, of what the majority view is on Issue—has defended and recommended to voters a view that is logically inconsistent with the majority view? This paper defends an affirmative answer to the Main Question. The last section raises the question of whether the trustee view of what obligations a legislator has in a representative democracy toward her constituents is mistaken. An alternative to the trustee view is presented and discussed, and it is concluded that this alternative view is implausible.
WHY NOT SOCIALISM
Authors: Joshi Hrishikesh
Published: February 2022

According to G. A. Cohen, the principles of justice are insensitive to facts about human moral limitations. This assumption allows him to mount a powerful defense of socialism. Here, I present a dilemma for Cohen. On the one hand, if such socialism is to be realized through collective property ownership, then the information problem renders the ideal incoherent, not merely infeasible. On the other hand, if socialism is to incorporate private ownership of productive assets, then Cohen loses the resources to distinguish his view from capitalism. For, if agents were ideally motivated, there would be no need for coercive taxation schemes and limitations on trade. Moreover, incorporating coercion drastically undermines Cohen’s original argument for socialism, which relies on an analogy to a camping trip among friends.
AGAINST RECATEGORIZING PHYSICIAN-ASSISTED SUICIDE
Authors: Reed Philip A.
Published: February 2022

There is a growing trend among some physicians, psychiatrists, bioethicists, and other mental health professionals not to treat physician-assisted suicide (PAS) as suicide. The grounds for doing so are that PAS fundamentally differs from other suicides. Perhaps most notably, in 2017 the American Association of Suicidology argued that PAS is distinct from the behavior that their organization seeks to prevent. This paper compares and contrasts suicide and PAS in order to see how much overlap there is. Contrary to the emerging view that emphasizes their differences, I argue that there is significant overlap such that we ought not to separate PAS into its own category, making it diverge from how we think about and address suicide more generally. I start by examining several prominent theories of suicide and argue that PAS fits squarely within them. I then examine several apparent differences between PAS and other kinds of suicide and argue that these differences are merely apparent or they do not justify treating PAS as a fundamentally different kind of thing from suicide.
THE RIGHT TO INQUIRE INTO THE PERSONAL WORLDVIEWS OF CANDIDATES FOR POLITICAL OFFICE
Authors: Robson Gregory
Published: February 2022

Challenging popular and philosophical views, I argue for three main claims. First, political leaders’ worldviews have a deep and underappreciated influence on their official conduct. Second, citizens have a robust claim right to inquire into leaders’ worldviews, and leaders have a corresponding moral duty to provide responses to such inquiries. Third, it is worthwhile for citizens to engage in such inquiry. A citizenry that took this argument seriously would engage in far more searching political inquiry.
BLAME IN THE AFTERMATH OF EXCUSED WRONGDOING
Authors: Piovarchy Adam
Published: February 2022

Control accounts of moral responsibility argue that agents must possess certain capacities in order to be blameworthy for wrongdoing. This is sometimes thought to have revisionary consequences, because reflection on our moral practices reveals that we often blame many agents who lack these capacities. This paper argues that Control accounts of moral responsibility are not too revisionary, nor too permissive, because they can still demand quite a lot from excused wrongdoers. Excused wrongdoers can acquire duties of reconciliation, which require that they improve themselves, make reparations for the harm caused, and retract the meaning expressed in the original wrong. Failure to do these things expresses a lack of regard for the victims and can make those wrongdoers appropriate targets of blame.
EDITORIAL MISCONDUCT
Authors: Baylis Françoise , Cattapan Alana , Snow Dave
Published: February 2022

This article interrogates the nature of editorial privilege and authorial integrity in peer-reviewed academic journals. Focusing on the authors’ experience with publishing a letter critiquing high-profile authors in a high-profile journal, the article identifies key concerns with (i) the time it took to complete the peer-review process, (ii) the failure to provide the authors with the peer-review reports, and (iii) the decision to rewrite our text instead of allowing us to respond to the peer-review comments. Our experience suggests that despite the existence of editorial codes of conduct, encroachments on authorial integrity still occur, and the lines between helpful copyediting and unhelpful rewriting of an article are not always clear.
NEUTRALITY, RELEVANCE, PRESCRIPTION, AND THE IPCC
Authors: Havstad Joyce C. , Brown Matthew J.
Published: February 2022

The Intergovernmental Panel on Climate Change (IPCC) states that its assessment reports are "policy-relevant and yet policy-neutral, never policy-prescriptive." Here, we investigate the meaning of that statement and conclude that at least one of the components within the statement—the claim to policy-neutrality—is extremely misleading. Misunderstandings of this neutrality claim have resulted in harm to the IPCC’s efforts and image. In an effort to help the IPCC restore its credibility, we explore possible interpretations of "neutrality," expose likely sources of misunderstanding, and suggest a plausible way of interpreting the term that is both defensible as a goal and fits with the IPCC’s actual activities. Future science advising efforts should carefully choose how they present their aims, to avoid the confusions created by unfortunate connotations of "neutrality."
FORTIFYING THE SELF-DEFENSE JUSTIFICATION OF PUNISHMENT
Authors: Cogley Zac
Published: February 2022

David Boonin has recently advanced several challenges to the self-defense justification of punishment. Boonin argues that the self-defense justification of punishment justifies punishing the innocent, justifies disproportionate punishment, cannot account for mitigating excuses, and does not justify intentionally harming offenders as we do when we punish them. In this paper, I argue that the self-defense justification, suitably understood, can avoid all of these problems. To help demonstrate the self-defense theory’s attraction, I also develop some contrasts between the self-defense justification, Warren Quinn’s better-known "auto-retaliator" argument, and desert-based justifications of punishment. In sum, I show that the self-defense justification of punishment is more resilient than commonly supposed and deserves to be taken seriously as a justification of punishment.

Russian methodologies of vocal training applied in a Czech children’s choir
Authors: Gadžijeva Elvira
Published: February 2022

This paper presents a dissertation thesis project that focuses on Russian methodologies of vocal training and their application in a children’s choir, which requires a careful choice of methodologies and methodological approach to organization of choir lessons. The paper begins with a brief description of the history and foundation of the Russian choral school and tradition of choral singing education, followed by a brief overview of the most popular vocal methodologists whose work has been dedicated to vocal training. The final part introduces two modern vocal training methodologies of leading musical trainers. The practical part of the future dissertation will deal with the selection of optimal exercises and their systematic development to help children improve their singing skills and musicality, as well as contribute to the cultivation of good singing habits. The aim is to enable school teachers or kindergarten teachers who are not professional musicians to use successfully the assembled methodology.
Clarinettist Milan Kostohryz: His contribution to the field of reconstruction of historical instruments and his innovative promotion of new instruments
Authors: Žitný Radek
Published: February 2022

My dissertation at the Department of Music Education and Culture at the University of West Bohemia is entitled “Milan Kostohryz. His contribution to music interpretation and pedagogy.” The dissertation focuses on an extraordinary musician, Milan Kostohryz (1911–1998), who had a significant impact on both the Czech and worldwide music community. He was highly professional, passionate, and meticulous, which was reflected in the wide scope of his activities. He was a reliable and sought-after player (in opera orchestras, chamber ensembles and as a soloist); a respected and successful teacher (almost all his students were successful in the field); an exceptional methodologist (he wrote a number of methodical articles and papers, which are relevant to this day); a researcher in the field of music history (he investigated the development of wind instruments in Czechia and revised dozens of old compositions). Many contemporary composers wrote works specifically for him, which he then premiered. Thanks to his extensive correspondence with dozens of music personalities all over the world, he contributed to several specialized international publications and was regularly invited to music conferences abroad (e.g. USA, Germany). His niche specialisation included official reviews of the quality of instruments (clarinets and saxophones) and mouthpieces available on the market at that time. He took part in the reconstruction of “Mozart’s basset clarinet” based on period sketches and built a working quarter-tone clarinet. His extensive interest in his field sets him apart from his contemporar - ies, many of whom were “just players”, rather than researchers. This dissertation is concerned mainly with his above-mentioned research. The principal resource for the research is an extensive written estate, with which I have been entrusted. It is currently deposited in the Czech museum of music in Prague (CMM). There are very few printed resources, as M. Kostohryz was not permitted to make substantial publications due to political reasons (see Bibliography).
Blues lyrics in teaching music and Czech at the grammar school
Authors: Sladký Aleš
Published: February 2022

My study is entitled: “Blues lyrics in teaching music and Czech at the grammar school” and now I will outline its fundamental contents, the basic conclusions of my study and the meth- ods used to help me reach these conclusions. The study is conceived as a comparison of five American and five Czech blues compositions, which are considered the most popular and basic works of the genre. I did this by analyzing several available charts focused on foreign blues songs and then compiled my list of the five “most popular” American blues songs based on the number of occurrences and locations of the songs in specific charts. For Czech songs, this procedure was more difficult, because I could not find any survey, discussion or ranking that focused specifically on blues songs. So, I proceeded here more or less intuitively and I put together a list of five songs according to my own knowledge of songs, according to the popularity of songs on the youtube music portal and the popularity of the artists who presented the songs. I analyzed the compositions mainly from the textual point of view; however, I did not forget the musical aspect. I was mainly looking for basic identical and different elements in the text area. I found several identical elements, not only in terms of themes, but also in the construction of texts and poetic turns. However, I also found certain textual differences in the Czech and foreign compositions. I will discuss these identical and different elements in more detail in the following text.

El propósito del presente artículo es establecer cómo los estilos de afrontamiento en niños influyen en su comportamiento prosocial, particularmente en aquellos afectados por el cambio estructural de la familia derivado del divorcio o separación de sus padres. En la actualidad, las estadísticas evidencian el aumento de los divorcios como secuela de la pandemia. El divorcio altera la parte psicoafectiva de los hijos, quienes manifiestan dificultades a nivel académico, cambios de estado de ánimo y de comportamiento, junto a problemas de interrelación con los demás. Asimismo, como cada familia funciona con una dinámica propia, también serán diferentes los modos de afrontar y recuperar la salud emocional, psicológica y social. Apreciaremos la relación de la conducta prosocial y los estilos de afrontamiento en niños de padres separados, teniendo en cuenta que esta se relaciona con la empatía, y consideraremos la influencia positiva o negativa de los miembros de la familia.

Authors: Sikora Monika , Wiśniewska-Wrona Maria , Arabski Michał
Published: February 2022

Abstrakt

Inżynieria tkankowa to interdyscyplinarna dziedzina badań, która stosuje zasady inżynierii i nauk przyrodniczych do opracowywania substytutów biologicznych, przywracania, utrzymywania lub poprawy funkcji tkanek. Łączy medycy-nę kliniczną, inżynierię mechaniczną, materiałoznawstwo i biologię molekularną. Chitozan jest związkiem, który może być stosowany na szeroką skalę w biomedycynie, m.in. jako nośnik leków, nici chirurgiczne, materiały opatrunkowe przeznaczone do przyspieszonego gojenia ran oraz rusztowania komórkowe w inżynierii tkankowej. Chitozon spełnia najważniejsze kryteria dla biomateriałów, m.in. kompatybilność, odpowiednie właściwości mechaniczne, morfologia i porowatość, nietoksyczność i biodegradowalność. Rusztowania chitozanowe mogą sprzyjać adhezji, różnicowaniu i proliferacji na powierzchni komórek. Z chitozanu można tworzyć różne formy funkcjonalne w zależności od potrzeb i wymagań, w tym: hydrożele 3D, gąbki 3D, folie i membrany oraz nanowłókna. Ze względu na unikalne właściwości fizykochemiczne biopolimer ten może być również wykorzystany do oczyszczania białek terapeutycznych z endotoksyn bakteryjnych, co jest dziś istotnym problemem w oczyszczaniu produktu końcowego w zastosowaniach medycznych. Obecnie terapie oparte na białkach rekombinowanych znajdują szerokie zastosowanie w terapiach celowanych, inżynierii tkankowej oraz szeroko pojętej medycynie regeneracyjnej. Dlatego tak ważny jest współistniejący, dobrze zapro-jektowany system oczyszczania produktu białkowego, który nie zmieni swoich zasadniczych właściwości. Artykuł jest przeglądem aktualnych badań nad zastosowaniem materiałów bioaktywnych na bazie chitozanu w medycynie regene-racyjnej różnych tkanek i narządów (m.in. tkanki chrzęstnej i kostnej, tkanki skórnej czy tkanki nerwowej).

Authors: Chen Kun , Wang Xinhua , Alghazzawi Daniyal M. , Wang Yanfeng
Published: February 2022

The power generation of distributed power generation systems in regional power grids is mainly affected by external environmental factors, and there are volatility and intermittent power generation issues. This paper establishes a relatively simple multiple linear regression prediction model to predict grid-connected photovoltaic power generation systems. The article uses a hybrid modelling method to filter more important weather forecast input variables through a step-by-step linear regression method to realize the visual calculation of power data. The research results show that the multiple linear regression equation methods proposed in the article have pervasive application value in the actual application of solar photovoltaic power consumption data.

Based on the shortcomings of the current intelligent management of distribution networks, the article designs and implements a remote intelligent detection system for live distribution networks. The article constructs and realises an algorithm based on a genetic algorithm (GA) and agent system. The algorithm is applied to energy-saving intelligent supervision of equipment in the distribution network. The simulation experiment shows that the integrated algorithm based on GA and agent system can accurately detect power quality in real time. At the same time, the algorithm can monitor the energy consumption of equipment in the distribution network under multiple disturbances.
Research on motion capture of dance training pose based on statistical analysis of mathematical similarity matching
Authors: Chen Qingwen , Albarakati Abdullah , Gui Lanlan
Published: February 2022

In order to verify the effectiveness and feasibility of the combination of motion capture technology and teaching, based on dance teaching, this paper proposes a dance posture analysis method based on feature vector matching and applies it to dance teaching.. The main research work includes the following: (1) according to the characteristics of human motion poses-free editing, extracting human skeleton models, establishing a human motion model database, analysing the application of motion capture systems in dance training, and proposing a method of feature plane similarity matching to calculate model components and motion parameters. After verification, the method has high accuracy and robustness for the analysis of human posture, so that dancers can accurately compare the differences with standard dance movements, and provide theoretical support for scientific dance training. (2) Aiming at the complexity of learning dance, a dance teaching method based on motion capture technology is proposed. Using motion capture technology, a whole complex dance movement is decomposed into many small segments to make a teaching animation, which guides students to learn based on small dance movement. Imitation makes the abstract theory vivid, intuitive and easy to understand, which is conducive for the innovation of education and teaching methods.

Authors: Wang Ke , Ma Qian , Zhou Hong-Tao , Zhao Ju-Mei , Cao Miao , Wang Shu-Dong
Published: February 2022

Natural silk fiber derived from the Bombyx mori (B. mori) silkworm has long been used as a luxury raw material in textile industry because of its shimmering appearance and durability, and as surgical suture for its high strength and flexibility. Regenerated silk fibroin, as the main protein extracted from the cocoons of the B. mori silkworm, recently has gained considerable attention due to its outstanding properties, including facile processability, superior biocompatibility, controllable biodegradation, and versatile functionalization. Tremendous effort has been made to fabricate silk fibroin into various promising materials with controlled structural and functional characteristics for advanced utilities in a multitude of biomedical applications, flexible optics, electronics devices, and filtration systems. Herein, reverse engineered silk fibroin extraction methods are reviewed, recent advances in extraction techniques are discussed. Fabrication methods of silk fibroin materials in various formats are also addressed in detail; in particular, progress in new fabrication technologies is presented. Attractive applications of silk fibroin-based materials are then summarized and highlighted. The challenges faced by current approaches in production of silk fibroin-based materials and future directions acquired for pushing these favorable materials further toward above mentioned applications are further elaborated.
Disposal: What Do We Do With A Dead Body?1
Authors: Lampard John
Published: February 2022

This article looks at the different ways in which dead human bodies are disposed of in modern society, particularly in Britain, and examines the social, theological, liturgical, and practical issues they raise for the Christian Church. It argues that the churches have failed to reflect theologically on cremation. In particular, it argues that ashes remain part of the body and should be treated with equal respect; the ashes of a Christian should be buried. Finally, it looks at the effect of the COVID pandemic on funeral practices.
Discernment or Direction: Dancing with the Spirit as we step out in Mission The Fernley-Hartley Lecture, 2019
Authors: Cox-Darling Joanne
Published: February 2022

This article draws from the developments in pneumatology, especially in respect to how the Spirit calls God’s people into mission and missional endeavour, in order to offer a critical insight into how the Fresh Expressions movement continues to equip the church to live faithfully. To do this, the article utilises research from ecumenical partners in mission in the UK, before arguing that Fresh Expressions (as an organisation as well as a set of principles and practices), has inherited much from the work of the Holy Spirit, but had not gone far enough to draw further conclusions or to self-resource itself from a strong pneumato-missional perspective.
Reflections on Morna Hooker at 90
Authors: Carleton Paget James N.
Published: February 2022

On 14 May 2021, the Cambridge New Testament Research Seminar was dedicated to a celebration of the life and work of Professor Morna Hooker on the occasion of her ninetieth birthday. What follows is the text of three contributions to that seminar, from James Carleton Paget, John Barclay, and Morna Hooker herself. Taken together, they provide an insight into the development of an outstanding biblical scholar, and the development of that discipline during her long and distinguished career. The papers are presented here in the same format as they were given at the seminar, with only minor corrections. It was decided not to add footnotes and bibliographies, but readers who wish to follow up references to Morna Hooker’s books and articles will find them readily available.

From Randomness in Two Symbols to Randomness in Three Symbols
Authors: Zylber Ariel
Published: February 2022

In 1909 Borel defined normality as a notion of randomness of the digits of the representation of a real number over certain base (fractional expansion). If we think of the representation of a number over a base as an infinite sequence of symbols from a finite alphabet A, we can define normality directly for words of symbols of A: A word x is normal to the alphabet A if every finite block of symbols from A appears with the same asymptotic frequency in x as every other block of the same length. Many examples of normal words have been found since its definition, being Champernowne in 1933 the first to show an explicit and simple instance. Moreover, it has been characterized how we can select subsequences of a normal word x preserving its normality, always leaving the alphabet A fixed. In this work we consider the dual problem which consists of inserting symbols in infinitely many positions of a given word, in such a way that normality is preserved. Specifically, given a symbol b that is not present in the original alphabet A and given a word x that is normal to the alphabet A we solve how to insert the symbol b in infinitely many positions of the word x such that the resulting word is normal to the expanded alphabet A ∪{b}.

Toponimi bentangan alam wilayah Kabupaten Siak, Provinsi Riau sebagai bekas pusat kerajaan Melayu di Riau sangat menarik karena sangat konkret menggambarkan lanskap lingkungannya. Kekonkretan toponimi itu dapat dilihat dalam relasinya dengan manusia, sejarah, geografis, bahkan budaya. Penelitian ini difokuskan pada toponimi rupabumi alami, antara lain perbukitan, tasik, selat, tanjung, dan sungai di Kabupaten dengan tinjauan linguistik antropologis. Aspek yang diteliti mencakup bentuk dan aspek geografis toponimi, fungsinya, dan sistem kognisi orang Melayu Siak yang tecermin di dalamnya. Penelitian ini dilakukan dengan pendekatan kualitatif dan metode deskriptif. Dari analisis data, toponimi alami di Kabupaten Siak dinamai dengan bahasa Melayu Riau. Bentuk leksikonnya berupa kata kompleks atau frasa yang selalu diawali dengan nama generik. Pada umumnya, toponimi dilatarbelakangi oleh aspek fisikal. Tidak banyak toponimi yang dilatarbelakangi oleh aspek sosial, kultural, atau oleh aspek fisik-sosial. Toponimi tersebut berfungsi untuk menandai, menjadi identitas formal, mendeskripsikan, dan sebagai pengingat latar belakang sejarah dan/atau sosial budaya suatu bentang alam. Makna leksikonnya mengungkapkan keeratan hubungan masyarakat Melayu Siak dengan lingkungannya. Toponimi alami di Kabupaten Siak mencerminkan kognisi orang Melayu Siak terkait dengan lingkungannya, baik fisik, sosial, maupun kultural dalam hal proses memanfaatkan, menghubungkan, konsep asimilasi, konsep akomodasi, konsep empirik, dan kreativitas. The toponyms of the landscape in Siak Regency as a former center of the Malay Kingdom in Riau is very significant in illustrating the landscape of its environment. The significance of toponym can be seen in its relation to humans, history, geography, and even culture. This research focuses on the natural topographical toponyms, including hills, lakes, straits, capes, and rivers in Siak Regency, Riau Province with anthropological linguistic reviews. This research was conducted with a qualitative approach and descriptive method. From the data analysis, the natural toponyms in Siak Regency are named after Riau Malay language. The lexicon is a compound word or phrase that always starts with a generic name. In general, physical aspects have underlain the toponyms. There are not many toponyms underlain by social, cultural, or physical-social aspects. The toponyms serve to mark, become an identity (formal), describe, and as a reminder of the historical or socio-cultural background of a landscape. The meaning of the lexicon reveals the closeness of the relationship between Siak Malay community and its environment. The natural toponyms in Siak Regency reflect the cognition of Siak Malays related to their environment, both physical, social, and cultural environments, in terms of utilizing and connecting processes, assimilation concept, accommodation concept, empirical concept, and creativity.

Published: February 2022

The authors introduced and addressed  several new subclasses  of the family of meromorphically multivalent -star-like functions in the punctured unit disk  in this study, which makes use of several higher order -derivatives. Many fascinating properties and characteristics are extracted systematically for each of these newly identified function classes. Distortion theorems and radius problems are among these characteristics and functions. A number of coefficient inequalities for functions belonging to the subclasses are studied, and discussed, as well as a suitable condition for them is set. The numerous results are presented in this study and the previous works on this subject are also connected together in this study.

Diare menjadi penyebab kematian kedua di dunia khususnya anak dibawah usia 5 tahun. Terdapat berbagai macam penyebab diare pada anak diantaranya adalah akibat pemberian Makanan Pendamping ASI (MPASI) yang tidak tepat. Penelitian ini bertujuan untuk mengetahui hubungan pemberian MPASI meliputi frekuensi pemberian MPASI, porsi pemberian MPASI, jenis MPASI dan cara pemberian MPASI dengan kejadian diare pada bayi usia 6-24 bulan di Puskesmas Temindung Samarinda. Penelitian ini merupakan penelitian analitik observasional dengan pendekatan case-control. Jumlah responden yang berhasil dikumpulkan pada penelitian ini sebanyak 60 responden dan dibagi menjadi 30 responden kelompok kasus (bayi yang terkena diare) dan 30 kelompok kontrol (bayi yang tidak terkena diare). Data responden diambil melalui wawancara orang tua responden dengan mengunakan kuisioner. Analisis bivariat dilakukan menggunakan uji chi-square dan jika nilai harapan kurang dari 5 maka uji yang digunakan adalah uji fisher’s exact. Hasil penelitian ini didapatkan hubungan antara frekuensi MPASI (p= 0.003), porsi MPASI (p= 0.008), dan cara pemberian MPASI (p=0,000) dengan kejadian diare. Pada penelitian ini tidak ditemukan hubungan yang signifikan antara jenis MPASI dengan kejadian diare (p= 0.166).

Air kelapa secara alami memiliki kandungan mineral dan gula yang dapat dijadikan sebagai minuman isotonik karena mempunyai kesetimbangan elektrolit yang sama dengan cairan tubuh. Kalium dan natrium adalah dua dari beberapa mineral yang terkandung dalam air kelapa dan merupakan unsur utama minuman isotonik. Di Indonesia, kelapa yang paling banyak dihasilkan adalah kelapa dari 3 varietas yakni kelapa dalam (Tall Coconut), kelapa genjah (Dwarf Coconut) dan kelapa hibrida (Hybrid Coconut). Ketiga varietas kelapa tersebut memiliki kandungan kalium dan natrium yang berbeda. Penulisan review artikel ini bertujuan untuk mengetahui kandungan kalium dan natrium yang terdapat dalam air kelapa dari 3 varietas, sehingga dapat diketahui varietas kelapa mana yang paling baik untuk digunakan sebagai minuman isotonik alami. Dalam penyusunan review ini digunakan teknik studi pustaka dengan membahas jurnal ilmiah yang memiliki topik terkait analisis kadar mineral dalam kelapa. Hasil review artikel menunjukkan bahwa air kelapa varietas kelapa dalam memiliki kadar kalium tertinggi yaitu sebesar 299.06 mg/100 mL dan varietas kelapa hibrida memiliki kadar kalium terendah yaitu 216.81 mg/100mL. Sedangkan kadar natrium tertinggi ada pada varietas kelapa genjah yaitu sebesar 16,22 mg/100mL dan kadar terrendah ada pada varietas kelapa dalam sebesar 11,03 mg/100mL. Karena mineral terbesar yang diperlukan dalam minuman isotonik menurut SNI 01-4452-1998 adalah natrium, maka dari hasil dapat disimpulkan bahwa air kelapa varietas genjah (Dwarf Coconut) adalah varietas kelapa yang paling baik untuk digunakan sebagai minuman isotonik alami.
