Authors: Lia Ratna
Published: April 2022

This article aims to identify and describe the transformation process and the factors that cause changes in the activities of cannabis farmers to Palawija farmers in the Lamteuba Aceh Besar community. This study uses a qualitative approach and a descriptive method. Data collection techniques in this study consisted of documentation, interviews, observation, and literature study. This study found that the transformation process of cannabis farmers into secondary crops in the Lamteuba Gampong community occurred because of the good opportunities, the availability of the location, the level of security, and the economic value of the secondary crops they manage. Factors that led to the transformation of cannabis farmers to secondary crops in Gampong Lamteuba, among others, were due to bad experiences among farmers, government support through outreach activities, and awareness/thought patterns from the farmers themselves.

Do The Scratchware Manifesto à Game Workers Unite: manifestos e reivindicações trabalhistas em duas décadas de videogame independente
Authors: Blanco Beatriz , Conceição Job da Silva Aline
Published: April 2022

O artigo propõe o debate do The Scratchware Manifesto (2000), considerando o desenvolvimento de jogos indies e as transformações observadas na produção e na criação de jogos dentro da forma neoliberal do capitalismo. Para tanto, abordamos o gênero textual manifesto como prática sociocultural de transformação, sendo o debate do The Scratchware Manifesto realizado no diálogo com outros manifestos, como Manifesto do Partido Comunista (MARX; ENGELS, 2012) e Rise of the Videogame Zinesters (ANTROPY, 2012), entre outros. Além disso, pontuamos alguns processos de criação, produção e circulação de jogos indies, a partir do alinhamento ou não desses com o mercado, bem como a precarização do trabalho. Por fim, indicamos iniciativas que estão promovendo relações alternativas de criação de jogos indies, assim como outras relações com o trabalho na indústria de jogos.

Jogos de tabuleiro do Império
Authors: Marques dos Santos Lucas , Mendes de Barros Laan
Published: April 2022

O artigo investiga a pervasividade da ideologia neoliberal nos jogos de mesa modernos. Nas últimas décadas, houve a ressurgência dos jogos de mesa e a consolidação de um novo mercado. Um dos marcos da nova era é a popularização do board game Catan, no qual os jogadores exploram uma ilha no começo da época das grandes navegações. Com base no levantamento das características dos 100 jogos mais bem ranqueados no fórum Board Game Geek, identificamos a prevalência de dinâmicas neoliberais em diversos jogos. A partir de contribuições da comunicação, dos estudos de jogos e do pós-colonialismo, vamos levantar algumas problemáticas do fenômeno dos jogos de mesa e os componentes ideológicos presentes. Das representações do colonialismo europeu, passando pelo imaginário do futuro neoliberal e chegando aos direcionamentos atuais da indústria.
Entre gamers e fãs
Authors: Greco Clarice , Dal Bello André
Published: April 2022

O objetivo deste artigo é discutir aproximações e distinções entre dois atores nas redes: o gamer e o fã de jogos. O debate inclui o autorreconhecimento dos jogadores como fãs ou como gamers, a elaboração de suas identidades em relação a estas denominações e os estigmas que elas carregam. A análise é feita por meio de questionário aplicado em comunidades de jogos e entrevista em profundidade com jogadores. A partir dos resultados, identificamos dois perfis principais de jogador na comunidade: aquele que produz conteúdo (jogador-produtor) e aquele que consome (jogador-espectador). Dentre as principais contribuições, destacamos a percepção de encontros de jogadores online como comunidades de fãs, a valorização do processo de autorreconhecimento do fã e as semelhanças e diferenças entre fãs e gamers, a partir do olhar dos próprios jogadores.
Dinâmicas de avaliação por pares na Steam
Authors: Andrada de Mello Leonardo , Da Silva Sandra Rúbia
Published: April 2022

Neste trabalho argumentamos que a gestão de conteúdos por pares na plataforma Steam, assim como seus sistemas de avaliação, geram fluxos que ocasionam que alguns conteúdos/produtos ganhem maior relevância nessa plataforma. Para tanto observamos as avaliações do jogo Bolsomito2k18 atentando para como se dão estes fluxos de informação. São articuladas discussões em torno de sistemas de avaliação. Tensionamos dinâmicas de comunicação em rede, pensando as mesmas como um sistema mediado pela gestão do capital lúdico. Concluímos que: 1 - diante dos fluxos comunicacionais, determinados conteúdos acabam ganhando mais relevância; 2 - os sistemas de avaliação podem sofrer distorções em especial pelo comportamento do próprio fluxo das avaliações; 3 - estas distorções podem ser muito mais benéficas para as empresas que para os usuários.

Authors: Abath Daniel
Published: April 2022

Um dos jogos mais esperados da última geração de consoles foi Death Stranding (2019), sobretudo em função da fama de seu realizador, Hideo Kojima, e das mecânicas de jogo inovadoras que eram demonstradas a partir de press releases e vídeos de divulgação de seus realizadores. Neste artigo, detemo-nos a observar a pervasividade do neoliberalismo em elementos de game design, mecânicas e plot narrativo do jogo em questão, sobretudo preocupados com o motivo da precarização do trabalho. Para tanto, contamos com as teorias do trabalho (ANTUNES, 1999), trabalho de plataforma (SRNICEK, 2017; SLEE, 2017; SUNDARARAJAN, 2016) e do neoliberalismo (DARDOT e LAVAL, 2016; FOUCAULT, 2008, HARVEY, 2008) para embasarmos nossa analítica crítica do jogo com base na observação de sistemas (LUHMANN, 2000).

Authors: Djenar Nancy Siti , Suryadi Joko
Published: April 2022

The protein contained in corn germ can be used as a raw material that has the potential to provide many benefits in the food, pharmaceutical, and plastic industries. Corn germ with the highest content of protein is around 12-18.4%. In this study, protein from corn germ was isolated and homogenized using tris buffer HCl at pH 7.2. To obtain the protein fraction, precipitation was carried out (salting-out) using a solution of (NH4)2SO4 with saturation levels of 25%, 50%, and 70% respectively. The purification process was carried out by dialysis for 24 hours. The dialysis produced pure protein with a concentration of 4.161%. Based on the identification of functional groups using an FT-IR spectrophotometer, it was shown that the isolated and purified corn germ protein contained four absorption bands, including amide A (3211.48 cm-1 and 3226.91 cm-1), amide I (1633 cm-1 and 1629.85 cm-1), amide II (1527 cm-1 and 1552.70 cm-1) and amide III (1296.16 cm-1). The four absorption bands correspond to the wavenumbers of corn protein stated in the literature and are estimated to contain albumin, globulin, glutelin, and zein.

Preparation of calcium compounds such as calcium hydroxide, calcium carbonate, and calcium oxide from chicken eggshells can be done through conventional methods that are cheaper and more practical, such as the sol-gel hydrolysis method and the coprecipitation method. In this study, the synthesis of calcium compounds from domestic chicken eggshells was carried out using two methods: the coprecipitation method and sol-gel method. Coprecipitation method consists of acid hydrolysis and alkaline hydrolysis. Sol-gel method consists of modification I and modification II. The AAS results showed that the calcium content from the hydrolysis of acids, alkaline, sol-gel modification I, and sol-gel modification II: 14.50%, 6.64%, 6.68%, and 9.93%, respectively. The FTIR showed that calcium compounds have four characteristic absorption bands, including O–H (3641.60 and 3448.72 cm-1) derived from Ca(OH)2 and H2O products, C=O (2981.95 - 1799 cm-1), and C–O (1448.54 – 874.68 cm-1) both of which from carbonate ions (CO3-) in CaCO3 both from eggshell and from the resulting calcium compounds, and Ca-O (711.73 cm-1) derived from CaO products. The results showed that the modification ll sol-gel method was the best because calcium compounds consisting of CaCO3, Ca(OH)2, and CaO were produced in a smooth texture, white color, and with the highest calcium content compared to other methods.

Tofu pulp which generally becomes waste can be used as a source of protein concentrate. Protein concentrates from tofu pulp have been obtained at various ratios of tofu pulp: ammonium sulfate and ammonium sulfate salt concentration. The research was conducted to obtain the highest protein yield and content of tofu pulp protein concentrate. This study used a completely randomized design (CRD) with the independent variable being the ratio of tofu pulp filtrate: ammonium sulfate (1:2, 1:3, 1:4, 1:5, 1:6, and 1:7 (v/v)) and concentrations of ammonium sulfate (30, 40, 50, 60, 70, and 80%), while the dependent variables were the yield of protein concentrate and protein content. Production of protein concentrate used the salting-out method with ammonium sulfate salt. The ratio of tofu pulp: ammonium sulfate 70% obtained the best ratio of 1:5   with a yield of 41.6% and protein content of 84.58%. Tofu pulp as industrial waste can be a potential source of protein concentrate because it has a high protein content.

Oil palm empty fruit bunches (OPEFB) are plantation waste that has the potential to be used as activated carbon. The main component of OPEFB is lignocellulosic which can be a source of activated carbon and utilized for Pb2+ ion adsorption. The use of activated carbon activated by NaOH still requires optimization, especially in determining the contact time and optimum adsorption pH. This study aims to determine the effect of pH and contact time on the adsorption of Pb2+ and to determine the efficiency of the adsorbent on the adsorption of Pb2+. In this study, activated carbon from OPEFB was carbonized at 300oC for 1 hour, followed by activation using NaOH 0.5%. The results showed that the use of pH 5 and a contact time of 90 minutes had a relatively higher Pb2+ adsorption than other conditions. However, the use of variations in pH and contact time had no significant effect on the adsorption of Pb2+ ions. Adsorbents with variations in pH 4, 5, 6, 7, and 8 were able to absorb Pb2+ of 99.73%, 99.86%, 99.74%, 99.79%, and 99.80%, respectively. Adsorbents with variations in contact time of 30, 60, 90, 120, and 150 minutes were able to absorb Pb2+ of 99.28%, 99.40%, 99.48%, 99.44%, and 99.48%, respectively.
Quantum modality of Cu-Nb clusters
Authors: Shokrvash Hussein , Motmaen Daniz , Talebi Elham Ghasem
Published: April 2022

A new class of materials was identified as Cu20Nb monolayer clusters,
which hosts strong correlation electrons. Direct observation show maps
of electron wave function patterns, where the symmetry, brightness and
size of features was directly related to the position of a Nb atom in Cu
lattice, around which the electron was bound. Using the Fourier
transform (FT) of the fractal dimension of the AFM images, these
clusters present quasi-particle interference (QPI), which reveals a
unique picture of electron waves and the trapping of further electrons
in the lattice. Furthermore, density functional theory (DFT)
calculations validated electronic features of the clusters with
remarkable accuracy. DFT calculations also revealed differences between
the lowest unoccupied energy (LUMO) and the highest occupied energy
(HOMO), and these phase gaps evolved in the ground state. These
phenomena provide evidence that electron correlation stimulates
electronic bands to pseudo-gap states. Indeed, our experiments pave the
way for realizing unconventional superconductivity in zero-dimension
materials.

Off-pump coronary artery bypass grafting with malignant tumor resection involving different organs: the comparison of long-term prognosis and risk factor analysis related to survival
Authors: Zhang Yiding , Li Fei , Yang Yang , Xiao Feng , Wang Jin
Published: April 2022

Aim: The aim of this study was to analyze the influence of the
primary site of tumor location on off-pump coronary artery bypass
grafting (OPCABG) surgery combined with concurrent tumor resection, and
to identify factors affecting the long-term survival. Materials
and methods: 57 patients with coronary artery disease (CAD) and
malignancy underwent simultaneous surgery were retrospectively enrolled.
The primary site of tumor locations and cancer stage were used as a
basis for grouping. The long-term survival among the subgroups was
compared, and the risk factors related to survival was analyzed.
Results: The median follow-up period was 40 months. The 5-year
cumulative survival rate of patients undergoing OPCABG and tumor
resection was 74%. There was no significant difference in long-term
survival among the 4 oncological location subgroups (P=0.8) while
significant difference was found among the 2 cancer stage subgroups
(P=0.0076). On univariable and multivariable Cox regression analysis,
only cancer stage was an independent predictor of the long-term
mortality rate (hazard ratio 5.42, P = 0.007). ﻿ Conclusion:
For patients with potentially curable cancer and surgically correctable
CAD, the safety of simultaneous surgery is confident. The primary site
of tumor location does not significantly affect the long-term survival
of these patients. The long-term survival rate strongly correlates with
tumor stage.

Published: April 2022

O aumento da comparabilidade dos relatórios financeiros entre os países é uma das principais motivações para o apoio permanente à convergência às normas internacionais de contabilidade. Além disso, a comparabilidade afeta os usuários finais dos relatórios financeiros, uma vez que os analistas de mercado podem utilizar as informações das empresas do mesmo setor econômico como referência para a elaboração da estimativa de consenso. Assim, o objetivo desta pesquisa foi investigar o impacto da comparabilidade dos relatórios financeiros na acurácia da estimativa de consenso dos analistas de investimento no mercado brasileiro após a adoção das IFRS. O estudo é quantitativo, descritivo e o período analisado compreende os anos de 2005 a 2015. Além disso, a comparabilidade foi mensurada pelo modelo de De Franco, Kothari e Verdi (2011) e, para testar a relação das variáveis, optou-se pela análise de dados em painel. Os resultados mostraram que a comparabilidade individual média entre as empresas não apresentou variações significativas no período de pós-adoção das Normas Internacionais de Contabilidade (IFRS). Todavia, a comparabilidade intertemporal das empresas ao longo do período apresentou variações positivas. Quanto à acurácia, não foram observadas variações significativas nos períodos antes e após a adoção das IFRS. No entanto, as variáveis comparabilidade média e intertemporal influenciam na acurácia de forma significativa e negativa. Assim, os resultados mostram uma associação significativa entre o aumento da comparabilidade dos relatórios financeiros no Brasil e um aumento na precisão das estimativas de consenso dos analistas com a adoção do IFRS.

Published: April 2022

O objetivo deste estudo é verificar, à luz da Teoria do Prospecto, se mulheres apresentam menor tolerância ao risco do que homens, em decisões organizacionais. Realizou-se experimento de campo com 236 gestores (115 mulheres e 121 homens) distribuídos em dois grupos, um de controle (decisões pessoais) e outro experimental (decisões organizacionais) e, após, avaliou-se isoladamente as 115 mulheres. Os dados foram analisados por meio de regressão logística, utilizando dois modelos. Os resultados indicam que a premissa inicial, referente decisões no campo pessoal, de que mulheres são menos tolerantes ao risco do que homens, se aplica com menor frequência quando as decisões são tomadas no campo organizacional. Além disso, a influência do gênero sobre a tolerância ao risco é mais evidente em situações envolvendo ganhos do que em situações de perdas. Os achados do estudo trazem reflexões sobre o tema ao constatar que premissas aceitas pela literatura no campo de decisões pessoais podem não ser aplicáveis ou totalmente válidas em decisões no campo organizacional e tampouco iguais para situações de ganhos ou de perdas.
THE INFLUENCE OF GENDER DIVERSITY ON MARKET VALUE: A COMPARATIVE STUDY BETWEEN EUROPEAN AND LATIN AMERICAN COMPANIES

Published: April 2022

Debates about gender diversity have addressed the influence of women in organisational environments, and their role in increasing economic and non-economic gains. In this sense, the present study aimed to identify how the perception of a company's value is affected by greater equality between men and women in an organisational environment.  Based on secondary data from the social axis of the Refinitiv EIKON database, a quantitative study, using multiple linear regression, was conducted on a sample of 2,195 companies from two blocks of countries: Europe and Latin America. For both country blocks, it was found that greater gender equality on a board of directors had a positive correlation with the market value of the company. Additionally, it was found, but only for Latin America, that a policy of wage equality between the genders, as well as gender equality in terms of management, had a positive correlation with the Tobin's Q indicator. The main innovation in this study is the quantitative approach, as most previous research has relied on qualitative interviews and observations to understand adherence to gender diversity in organisations. The results are robust for the econometrics used and provide support on the potential to broaden the discussion on gender equality in the business environment, identifying and quantifying the influence of women on company values. The study opens space for discussion on the importance of gender quotas in companies. Policy used in Europe.

This research aimed to observe quantitatively the effect of temperature and pH on protease activities from thermophilic bacteria collected from Lejja—Hot springs.  Spectrophotometry on the casein substrate was used to test the proteolytic activity of the crude protease.  Mixtures of enzyme and casein were incubated at various temperatures and pH for 20 minutes. The absorbance of tyrosine from protein hydrolysis was determined by spectrophotometry on λ 280 nm. Temperature and pH impacted on protease activity were determined at temperature (60; 65; 70; 75; 80; 85 and 90oC) and pH (6.0; 6.5; 7.0; 7.5; 8, 0; 8,5 and 9,0). Results showed that treatment of temperature variations and pH had a significant effect on protease activity. Crude extract of Bacillus licheniformis protease showed that the highest activity at 80oC and pH 7.5 was 0.1303 unit/ml/minute. Bacillus stearoformis showed the highest enzymatic activity of the protease at 85oC, and pH 7.5 was 0.1226 Unit/ ml/minute. In comparison, Bacillus coagulans reached optimum activity at 75oC, and pH 7.5 was 0.2052 Unit/ml/minute. Isolates of Bacillus licheniformis, B. coagulans and B. stearoformis are bacteria that produce thermostable protease enzymes that can be developed as a source of genes and as a producer of the enzyme itself.

AbstrakPenelitian ini membahas metode percepatan dinamika kuantum adiabatik  pada sistem spin tunggal yaitu dinamika spin yang bergerak pada keadaan awal up (atas) akan bergerak ke down (bawah) pada keadaan akhir. Metode ini disebut skema fast forward. Metode ini pertama kali di usulkan oleh Masuda dan Nakamura. Dalam metode ini, skema percepatan dibangun dengan menambahkan suku interaksi penggerak ke Hamiltonian awal dan mempercepatnya dengan menggunakan faktor penskalaan waktu yang bernilai besar dan parameter adiabatik yang menuju nol (0) dan bertujuan mewujudkan dinamika kuantum adiabatik pada waktu yang singkat dan dengan penambahan medan magnet penggerak. Hamiltonian penggerak dan medan magnet penggerak ini menjamin spin tunggal dapat bergerak dari keadaan awal ke keadaan akhir  dalam waktu yang singkat tanpa mengubah karakteristik awalnya. Kata kunci: Adiabatik, Dinamika Kuantum, Spin tunggal AbstractThis study discusses the method of accelerating adiabatic quantum dynamics in a single spin system, namely the dynamics of a spin that moves in the up initial state will move down in the final state. This method is called a fast forward scheme. This method was first proposed by Masuda and Nakamura. In this method, the acceleration scheme is constructed by adding the driving interaction term to the initial Hamiltonian and accelerating it by using a large time scaling factor and adiabatic parameter towards zero (0) and aims to realize adiabatic quantum dynamics in a short time and  by adding a driving magnetic field. The driving Hamiltonian and the driving magnetic field ensure that a single spin can move from its initial state to its final state in a short time without changing its initial characteristics. Keywords : Adiabatic, Quantum Dynamics, Single Spin

Logam yang keras, lunak, ulet, kemampuan kerja tinggi dapat diperoleh melalui perlakuan panas. Peningkatan kekerasan logam dapat dilakukan dengan proses perlakuan panas meskipun logam tersebut rendah karbon. Baja karbon rendah dikenal lunak dan lemah serta ulet dan tangguh, serta relatif murah dibandingkan dengan jenis baja karbon lainnya. Karena sifatnya ini, maka perlu dilakukan perlakuan agar lebih kuat. Proses umum untuk baja karbon rendah adalah menambahkan karbon ke paduan untuk meningkatkan kekerasannya. Pada penelitian ini dilakukan penambahan karbon dari arang tempurung kelapa, kemudian dilakukan pengerasan pada suhu 875 0C, dan dilakukan tempering. Dari pengujian kekerasan, nilai tertinggi ditemukan pada proses carburising dan flame hardening dengan nilai 269,11 kg / mm2 . Nilai uji keausan terendah terdapat pada proses carburising dan flame hardening yaitu 0,00010 mm³ / kg.m, dan laju korosi terendah pada proses carburising yaitu 0,129 mpy.

Fluids are a shape of a matter which have substance liquids, gases and plasmas. In our daily life, fluids become important part, such as part of our blood and also help our body getting nutrients. It is well known that fluid motion can be described in mathematical model in especially in form of partial differential equations (PDE) and called as Navier Stokes Equations  (NSE). The Navier Stokes equation is derived from balance of conservation of mass and conservation of momentum. In this paper, we consider the solution formula of the linearized of the Navier Stokes Equation (NSE) with the initial boundary value (IBV) problem in half space without surface tension. The model problem under consideration covers of non-linear fluid type. We solve the solution formula of velocity and density of the model problem by using Fourier transform and partial Fourier transform method. The strategy geting the solution of the model problem is based on the analysis of some resolvent of the model problem which obtained by using Laplace transform of the Stokes equations. Therefore, In particular, the formula of velocity and density of the Stokes equation are obtained.

Wilayah Jawa memiliki aktivitas seismik yang tinggi akibat terletak di zona subduksi serta keberadaan beberapa sesar di daratan. Wilayah Jawa juga memiliki jumlah penduduk dan pertumbuhan infrastruktur tertinggi, sehingga upaya mitigasi harus dilakukan untuk mengurangi risiko gempa. Langkah paling penting untuk mengatasi hal tersebut adalah dengan memiliki ground motion model (GMM) yang sesuai dengan wilayah Jawa. Pada studi ini dibuat set data strong motion yang terdiri dari Peak Ground Acceleration (PGA), parameter gempa, dan kondisi situs pada periode 2010-2021. Data tersebut kemudian digunakan untuk memilih GMM yang memiliki residual paling rendah. Analisis dilakukan berdasarkan grafik histogram residual dan nilai standar deviasi untuk mendapatkan model yang terpercaya. Hasil penelitian menunjukkan beberapa model memiliki performa yang baik dalam memerkirakan nilai PGA. Model yang terpilih dapat digunakan untuk memerkirakan dampak gempa subduksi maupun crustal wilayah Jawa di masa depan.
