High-frequency retail data: the interests of the state, enterprises and scientific organizations
Authors: Timiryanova V. M.
Published: May 2023

The rapid development of technologies for collecting and analyzing big data, including those characterizing trade, is currently taking place. This data, with a high degree of detail, takes into account the whole variety of consumer decisions, which allows them to develop key management proposals on what, where and when to produce and sell. Banks, retail chains, and the state are actively interested in these data. At the same time, individual small and medium-sized enterprises weak use of big data in their activities. The purpose of this study is to highlight the problems and prospects for their application for management purposes, based on an analysis of the current practice of using high-frequency retail data. As a result of the study, the features of the available data of retail companies, payment systems and OFDs, which are manifested in their different structure and limitations for use in the development of management decisions, are highlighted. It is shown that big data characterizing retail trade is available to a narrow circle of people who, as a rule, have their own interests, which are not yet consistent with the idea of open publication of these data, even for scientific purposes. There are very few research publications based on high-frequency fiscal data. Such closeness of data does not create prerequisites for the active development of skills in working with them in most enterprises and organizations, which determines the weak use of microdata for management purposes.
HÉR! An Exploration of Artistic Agency - Media Repository

Media repository published as part of Halla Steinunn Stefánsdóttir's doctoral thesis 'HÉR! An Exploration of Artistic Agency' (2023). See here: https://bit.ly/LUResearchPortal

Abstract:
This doctoral thesis is concerned with agency in the work of a performer, curator, and composer, and how these agencies are socio-culturally constructed. Grounded in creative practice as primary research methodology, the project builds on feedback loops between creation, analysis, and interpretation. The aim is to better understand the conventional norms that define the roles of composer and performer and, further, to explore more dynamic approaches to these agencies through the perspectives of a composer, performer, and curator active in the fields of contemporary music and sound art. The project responds to the following research questions:

o How can ecological-enactive and post-phenomenological perspectives on musical practice within Western classical music challenge current understandings of the roles of performer and composer?
o What artistic methods can be employed to provide a more robust understanding of the fluidity of these roles, to uncover their potential for artistic renewal in the creation and performance of contemporary music?

The research was designed as a series of micro-laboratories to look at agency through artistic collaboration in situations set in the concert hall, the recording studio, the virtual domain, and ecological sound art. This resulted in electroacoustic compositions, multi-channel installations, and site-specific work, including performances within a sonic hologram and with artificial intelligence. The analytical approach was built on autoethnography, and audio and video analysis through stimulated recall.

The findings outline how the technological, non-human, and human agencies of environments affect and shape processual work. The analysis highlights how co-relation between theory and practice may both serve to unpack the pre-conditioning of agency, while the artistic experimentation in the laboratories seeks to explore other agential relations. Here, the intentionality of the technologies used in the lab have unfolded new perspectives on the conventional roles of composer and performer, while enabling the development of more dynamic practices. Through a study of the author’s curatorial practice, the role of a curator is understood not as defined by prescribed methods, but rather as dependent on the negotiation of the many agencies at play in artistic practice. The method development of the project has implications for the design of artistic research through the model of the laboratory. Herein, the use of audio and video technologies, particularly their application within stimulated recall methods, are integrated parts of analysis and artistic creation. The artistic research laboratory is proposed as a framework through which the potential of artistic research in music—as a vehicle for the development of new practices in professional contexts and in teaching environments—is substantiated and facilitated.
In silico identification of gene targets to enhance C12 fatty acid production in Escherichia coli

Published: May 2023

The global interest in fatty acids is steadily rising due to their
wealth of industrial potential ranging from cosmetics to biofuels.
Unfortunately, certain fatty acids, such as monounsaturated C12, cannot
be produced cost and energy-efficiently using conventional methods.
Biosynthesis of fatty acids using microorganisms can overcome this
drawback. However, rewiring a microbe’s metabolome for increased
production remains challenging. To overcome this, sophisticated
genome-wide metabolic network models have become available. These models
predict the effect of genetic perturbations on the metabolism, thereby
serving as a guide for metabolic pathways optimization. In this work, we
used constraint-based modeling in combination with the algorithm
Optknock to identify gene deletions in Escherichia coli that
improve the C12 fatty acid production. Nine gene targets were identified
that, when deleted, were predicted to increase C12 titers. Targets play
a role in anaplerotic reactions, amino acid synthesis, carbon metabolism
and cofactor-balancing. Subsequently, we constructed the corresponding
(combinatorial) deletion mutants to validate the in silico
predictions in vivo. Our highest producer (Δ maeB Δ
ndk Δ pykA) reaches a titer of 6.7 mg/L, corresponding to
a 7.5-fold increase in C12 fatty acid production. This study
demonstrates that model-guided metabolic engineering is a useful tool to
improve C12 fatty acid production.

Covid-19 pandemic was a stress test to Pakistan’s healthcare systems, social policies, and political stability. This study explores Pakistanis’ lived experiences during the advent of the Covid-19 pandemic, including the impacts of Covid-19 on their livelihood, as well as their perceptions and opinions of their government’s policy measures. Through a questionnaire survey of 1000 participants living in the cities of Islamabad and Rawalpindi, this study found that livelihood, including food supply and household finance were main challenges facing many Pakistanis during the Covid-19 pandemic; and the level of vulnerabilities were tightly related to socio-demographic characteristics like gender, living arrangement, and sector of employment. Men are more likely to suffer from hunger, and men work in the informal sector and living in a multigeneration (or multi-nuclear household) tend to be more vulnerable than others. Almost all employed respondents reported income deduction and most of them reported the increase of household expenditure during the pandemic. The mixed opinions on the government’s Covid-19 measures and policies were associated to respondents’ socio-demographic characteristics. There were sharp gender differences as well. Men were more in agreement with the government’s policies than women, which implies a gender based information access disparity.

Authors: Kiram Yanuar , Andri Gemaini
Published: May 2023

Motorik merupakan proses konsekuensi yang terjadi sepanjang hidup, yang dapat diartikan bahwa sepanjang makhluk hidup bernyawa pasti akan mengalami gerak,motorik terjadi akibat adanya  koordinasi antara organ-organ pada tubuh. Masa kecil adalah “saat ideal”untuk mempelajari kemampuan motorik. Hal ini dikarenakan organ tubuh anak masih mengalami pertumbuhan sehingga aktivitas gerak mudah diperbaiki dan diperhalus, anak belum memiliki banyak keterampilan sehingga mempermudah mempelajari keterampilan baru, pada masa kecil tingkat keberanian anak lebih tinggi sehingga menimbulkan motivasi yang tinggi untuk mencoba hal baru, anak kecil menyukai kegiatan pengulangan sehingga pola otot akan lebih terlatih, dan anak kecil memiliki waktu yang banyak untuk belajar melakukan keterampilan motorik.

Permasalahan mitra yaitu guru-guru PJOK Kota Padang yaitu dalam penyampaian proses pembelajaran motorik dengan program aktivitas bermain yaitu umumnya pembelajaran yang diberikan masih bersifat konvensional yaitu dengan menjelaskan isi buku, teks ataupun penjelasan secara langsung. Hal yang disampaikan ke anak sering tidak tersampaikan, sehingga menyebabkan tujuan pencapaian gerak tidak terlaksana. Solusinya antara lain: 1) Memberikan pengetahuan kepada guru-guru PJOK tentang pentingnya motorik dan metode-metode pengembangan motorik.2) Melakukan Pelatihan dan pendampingan penyusunan program Outdoor education pengembangan motorik melalui permainan, 3) memberikan pengetahuan dan keterampilan dalam metode tes gerak dasar.

Luaran dari kegiatan ini adalah: 1) Peningkatan pengetahuan dan pemahaman kepada guru tentang pentingnya Motorik anak, dan akibat bagi anak jika kemampuan motorik  tidak dimiliki; 2) Peningkatan keterampilan dalam menyusun Program Outdoor Education dengan pendekatan experiental learning yang menarik bagi anak dan dapat membuat anak suka bergerak; 3) Produk dihasilkan Modul berisikan Program Outdoor Education dengan pendekatan experiental learning.

Published: May 2023

Daerah binaan PKM ini adalah Nagari Painan Selatan Kecamatan Koto IV Jurai Kabupaten Pesisir Selatan, yang  memiliki populasi lansia cukup besar. Adapun permasalahan mitra: (1) Kegiatan pada posyandu lansia tergolong monoton sehingga kurangnya minat peserta untuk datang, kegiatan posyandu hanya tergambar pada proses pemeriksaan kesehatan lansia saja, misalnya pada penimbangan berat badan, cek tekanan darah kadang juga cek kolesterol dan asam urat. Belum ada kegiatan yang bertujuan untuk peningkatan kebugaran jasmani dan senam lansia yang hingga saat ini jarang dilakukan. Hal ini disebabkan juga karena masih kurangnya instruktur yang berkompeten dalam memberikan penyuluhan dan pelatihan dalam rangka mewujudkan masyarakat yang sehat jasmani dan rohani. Kegiatan pada Posyandu kurang bervariasi dan belum ada penekanan khusus bagi partisipan lansia dalam melaksanakan senam. Oleh sebab itu perlu dilakukan penyuluhan dan pelatihan tentang kebugaran jasmani khususnya senam lansia. Hasil yang dicapai adalah pemahaman terhadap 1) olahraga khususnya senam lansia 2) pentingnya tes kebugaran 3) pelaksanaan senam lansia yang baik dan benar. Adapun Permasahan yang ke dua (2), mengenai  ketenagakerjaan terutama untuk lansia tidak potensial, mayoritas dari mereka adalah lansia yang kini sudah tidak lagi bekerja meskipun mereka masih ingin bekerja. Masih kurang produktifnya sebagian lansia sehingga membawa konsekuensi berkurangnya pendapatan yang dapat menyebabkan kemiskinan lansia. Banyak waktu luang yang dimiliki oleh lansia dirumah, karena mereka hanya melakukan kegiatan seputar RT. Oleh sebab itu perlu diberikan pelatihan keterampilan kreativitas dengan memanfaatkan bahan-bahan serat alam dan tali macrame sebagai upaya mencegah demensia, meningkatkan produktivitas lansia, meningkatkan interaksi sosial antar lansia, sekaligus mengisi waktu luang lansia dengan kegiatan bermanfaat. Hasil yang di dapat adalah menambah keterampilan dan berpeluang untuk dikembangkan menjadi sebuah usaha yang mampu memberikan nilai tambah bagi keluarga dengan modal yang tidak besar tetapi mampu menghasilkan nilai ekonomi yang cukup tinggi. Kegiatan dilaksanakan dengan  Training of Trainer (TOT) dengan cara memberikan materi melalui ceramah, kemudian dilanjutkan dengan praktek langsung
Une histoire des connecteurs logiques. Causalité, argumentation, conséquence, finalité et concession
Authors: Wüest Jakob
Published: May 2023

La tradition grammaticale nous propose une classification des connecteurs qui tient insuffisamment compte du fait que la plupart d’entre eux sont polysémiques. Le plus grand défaut de la classification traditionnelle, c’est qu’elle ignore l’argumentation, qui est une fonction logique fondamentale. Nous proposerons donc une nouvelle catégorisation des connecteurs logiques (y incluant la conséquence, la finalité et la concession) et nous la testerons en analysant 18 textes français, de la chanson de Roland jusqu’au français parlé parisien des années 2000.

Method of object-oriented modeling of steam turbine plants taking into account variations in turbine efficiency under variable operating modes
Authors: Gubarev A. Y.
Published: May 2023

The article proposes an object-oriented method for modeling steam turbine plants. The novelty of the method is in the application of a steam turbine model that takes into account variations in internal efficiency under variable operating modes.The article presents the results of theoretical substantiation of nonlinear dependence of the power of the turbine compartments on the steam flow passing through them, based on the change in the internal efficiency of the stages under variable modes described by the Stodola-Flugel equation. An empirical dependence of the efficiency of the stage operation on the relative steam consumption is proposed. Recommendations on the use of empirical form in the development of models of steam turbine compartments are given. The empirical dependences of the relative internal efficiency of turbine compartments obtained from the results of thermal tests of an operating turbine unit are presented.As a factor of practical significance of the research, a model of PT-60-130/13 type steam turbine plant has been developed involving the use of an object-oriented programming language. Recommendations on the description of classes of objects within the steam turbine plant. The developed STP model enables to simulate any operating modes depending on electrical and thermal loads, as well as to take into account the influence of deviations of external factors from nominal values when developing a system of corrections or estimating an increase in fuel consumption associated with these deviations.

El presente artículo resume la investigación realizada para indagar sobre la faceta del industrial alemán Leo Kopp como inversionista en finca raíz en Bogotá, con el propósito de encontrar la huella construida de su aporte al desarrollo urbano y arquitectónico de la capital colombiana y reconocer su valor como patrimonio de la ciudad, tanto por su valor arquitectónico, como por el histórico y testimonial.
Se trató de una investigación basada en un estudio de caso histórico-arquitectónico con una aproximación de tipo exploratorio a partir de una investigación documental, con la que se logró identificar las propiedades de Leo Kopp en Bogotá e investigar algunos datos históricos sobre ellas.
Se indagó sobre la inversión de Kopp en los predios que dieron origen a Bavaria, Fenicia, La Perseverancia, algunos edificios de renta en el barrio Las Nieves y unos lotes en el barrio Quesada. La investigación permitió conocer los antecedentes históricos de estos lugares y reconocer la importancia que tuvieron en el desarrollo de Bogotá. Al indagar sobre su historia se encontró que la mayor parte de las edificaciones ya no existen y es muy difícil encontrar información sobre las mismas. El desarrollo de Bogotá y, en algunas partes, el deterioro, destruyeron la huella construida de la presencia de Leo Kopp en Bogotá, que su faceta como inversionista podría mostrar.

Deprojectification of agile: The new orthodoxy of long-term product teams
Authors: Nesheim Torstein
Published: May 2023

Agile management thinking has influenced organisations in several ways, but the focus of this paper is on the deprojectification of agile software development. The new agile orthodoxy has been promoted by popular books, in blogs and by Spotify and other firms: agile teams should be aligned to products or domains (not projects); cover development, maintenance and operations (to reduce handover problems); and have a long-term character (to build trust, identity and domain knowledge). We first describe and contextualise the new agile orthodoxy and then, based on an empirical study of two different “agile cases,” we describe and analyse how employees and middle managers perceived the rationale behind the change to long-term teams, how they understood teams as the basic unit of the structure, their perceptions of the resource and disciplinary dimensions of the organisation and the decline of projects and project managers.

Published: May 2023

The increasing area of land burned in 2021 makes the government urgent to map areas prone to forest fires in Situbondo Regency. This study analyzes areas prone to forest and land fires using the SMCA method. The research analysis used variables of land cover type, the greenness of vegetation, vegetation humidity, land surface temperature, and human factors. The human elements in question are accessibility (distance from the road network) and distance from human activities (distance from settlements, fields, and plantations). The conclusion analysis of forest fire-prone areas is divided into three classes that are high, medium, and low. From the vulnerability model that has emerged, it was found that most of Situbondo Regency have a high grade of forest fire vulnerability with an area of 652.66 km² (39.08%). The areas with the level of vulnerability of the middle, low, and non-vulnerable classes, respectively, are 532.12 km² (31.87%), 306.46 km² (18.35%), and 178.65 km² (10, 70%). The results of statistical tests using the ordinal logistic regression method show that natural factors for forest and land fires had a higher level of influence (? = 4.824) on forest and land fire vulnerability compared to human factors (? = 1.051).

Natural mangroves can be found in Nusa Lembongan, which is bordered by coral reefs, while in the Perancak Estuary, some of the lands are former ponds. The aim of the study was to determine the density, canopy cover, and organic carbon content in mangrove sediments. Data were collected from 3 stations, using transects measuring 10 x 10 m to determine density, height, trunk circumference, and canopy cover, as well as macrozoobenthos sampling. The mangrove density in Lembongan is very high, the tree height reaches 8 – 10 meters, and the mangrove canopy cover is in a good category. The macrozoobenthos diversity index is in the medium category and the carbon content in the sediments is high. Mangroves in Perancak Estuary are densely dense, with an average tree height of 8 meters, and canopy cover in the good category. The index of macrozoobenthos diversity was moderate and the organic carbon in the sediments was lower than in the mangroves at Nusa Lembongan. The character of the mangrove vegetation is different in the two areas. The Nusa Lembongan mangrove growing area is directly opposite the sea, but in the Perancak Estuary, it tends to be closed and flows by a large river around it. The mangrove growth zone is still natural in the Nusa Lembongan area, in contrast to the Perancak Estuary mangrove area which has been rehabilitated at several points.

Pakerisan watershed is one of the watershed that has not followed the rules of soil and water conservation. This can destroy soil aggregates and cause high erosion. This study aims to predict the level of erosion and to plan soil and water conservation. Erosion prediction uses the USLE (Universal Soil Loss Equation). The prediction erosion showed that erosion is classified from slight to severe.

Published: May 2023

This research aims to study the locals’ perceptions towards English in association with the local tourism destination development. Since language and tourism are interwoven, the use of language is linked to the likelihood of its popularity or infamy. It is undeniable that Indonesia requires English in all tourism sectors. The problem is that Indonesian's English proficiency in general is still in the lowest position among the members of the MEA. This has become one of the obstacles to make local tourism sites more competitive in the international sphere. Recognizing the communities’ perceptions to English would be a meaningful step to advance the potentials of the local tourism destination. Therefore, two issues that this research is concerned about are: the locals’ perceptions and the problems that might pose if English were introduced. The descriptive qualitative method employed.

Hermeneutika Double Movement Fazlur Rahman Dalam Studi Hadits
Authors: Wahdah Yuniarti Amalia
Published: May 2023

The stagnation that occurs in the study of hadith science causes Fazlur Rahman to offer a new methodology in understanding hadith, namely Double Movement hermeneutics. It includes two movements in which the first movement starts from the context of the present to the time of the hadith conveyed by the Prophet by studying textually as well as socio-historically. The second movement is to return to the present by applying the moral ideals implied in the hadith. The Prophet's comment in the hadith forbidding women's leadership is just a response to the Queen of Persia's appointment at the time, not a shar'i provision in choosing a leader, according to the Double Movement theory. So that nowadays women may be elected to serve as leaders on condition that they have adequate authority and leadership.

Pemikiran M. Syahrur Tentang Pakaian Perempuan (Dari Konfigurasi Aurat Hingga Konstruk-Hirarki Pakaian Perempuan Dalam Islam)
Authors: Parwanto Wendi
Published: May 2023

Muhammad Syahrur's thoughts in several disciplines of discussion are quite interesting for researchers to discuss, both in the fields of hadith, interpretation, fiqh and al-Qur'an hermeneutics. The main theory that is of great interest to researchers in Syahrur's thinking is the limit theory. And it is from this limit theory that Syahrur constructs his thoughts on many Islamic themes, including women's clothing, genitalia and so on. So in this study, we will examine in more detail about the construction of aurat and women's clothing according to Muhammad Syahrur. This research is a library research with the main sources are two literatures by M. Syahrur, namely: Al-Kitabu wa Al-Qur`anu and Nahwa Al-Jadidah li Al-Fiqh Al-Islamiy. While the secondary sources are other relevant literature. The conclusion of this article is that the construction of Muhammad Syahrur's thoughts on genitalia, headscarves, zinah (jewelry), and all women's clothing comes from the limit theory (hudud). According to him, the upper and lower limits depend on the extent to which a person is ashamed. However, not all of his thoughts tend to contradict the majority of Muslim scholars, because before he concluded the limit theory (hudud), he also explained about the derivation of words, such as headscarves, khimar, and others.
