Durante la molienda de los sulfuros minerales en molinos de acero se llevan a cabo reacciones galvánicas entre el hierro de las bolas de molienda y las especies sulfurosas provocando la oxidación superficial de los elementos que constituyen los sulfuros, afectando el éxito de la siguiente etapa. Por tal razón se estudió y caracterizó el efecto de los medios de acero, el pH inicial y el tiempo, en la fisicoquímica de la pulpa de molienda de arsenopirita (FeAsS). Los resultados experimentales muestran la variación del potencial de iones hidrógeno con el tiempo, resultado del contacto galvánico entre el hierro y las partículas de arsenopirita, provocando la oxidación de los elementos que constituyen el mineral tal como; hierro (Fe), arsénico (As) y el azufre (S), este conlleva a la formación de ion sulfato acidificando la pulpa, además, tiende a aumentar la conductividad eléctrica k (µS) de la pulpa. Por otro lado, la concentración de oxígeno disuelto disminuye significativamente desde un valor de alrededor de 8 mg/L hasta prácticamente cero a valores de pH más alcalinos y tiempos de 20 minutos, junto a esto el ambiente químico de la pulpa muestra potenciales óxido reducción negativos y disminuye continuamente con el progreso de la molienda.

Colonial Vestiges, Indigenous Policy-Logical-Framework, and Sustainable Development in Nigeria
Authors: Okafor Samuel O.
Published: May 2022

Countries in Africa continue to represent practical examples of failed nation-states due to the persistence of all known indicators of underdevelopment.  Ironically, the continent has a proud social history that eulogizes its contribution to global development. However, a careful look at most of the countries (such as Nigeria) that make up the continent reveals an image of adverse human development realities. This negative socio-economic scenario has put the continent at the forefront of foreign aid destinations even though Africa has all it takes to drive a healthy development agenda. The manner with which development policies are far removed from the reach of the masses in terms of their input, needs, and aspirations, shows the nature of the colonial character that surrounds policymaking in a country like Nigeria. It is the submission of this paper, that decolonizing policy-making processes and ensuring that the masses are integrated into the process would go a long way to synthesize the indigenous aspirations, elite groups, and valid experience for sustainable development. Hence, using the colonial policy template diagram and the post-colonial policy template diagram of successive governments, the paper evaluated the structure of policymaking and implementation in Nigeria and the disconnection between policy objectives and realities in the economy. Based on the findings, the paper recommends an indigenous and populist informed policymaking process to reverse the colonization of development policies in Nigeria and to engender a sustainable development policy trajectory.

Bir ülkenin en başta gelen makroekonomik amaçlarından birisi, ekonomik büyüme hedefinin gerçekleştirilmesidir. 1960’lı yıllara dek büyümenin yegâne unsurlarından biri olarak kabul gören fiziki sermaye faktörüne alternatif olarak ortaya konulan bilgi ve yetenek gibi maddi olmayan unsurlar, büyüme tarihinde yeni bir dönem başlamasına da vesile olmuştur. Merkezine insanı alan ve beşeri sermaye olarak adlandırılan bu yeni kavram, toplumların gelişiminde büyük rol üstlenen; eğitim, sağlık ve nüfus gibi demografik faktörler aracılığıyla da dikkatleri üzerine toplamıştır. Ülkeler açısından sürdürülebilir nitelikte bir ekonomik büyümenin elde edilmesi, aynı zamanda o toplumu oluşturan bireylerin, hem fiziksel hem de ruhsal yönden sağlıklı olmalarına bağlıdır. Bu yönüyle sağlık kavramı, bir yandan işgücünün verimliliğini artırarak beşeri sermayenin oluşmasına katkı verirken, öte yandan da ekonomik büyümeyi desteklemektedir.

Bu çalışmada Türkiye’nin de dâhil (olduğu ve literatürde D8 olarak adlandırılan 8 ülke için sağlık harcamaları ve ekonomik büyüme arasındaki ilişki 2000-2019 arası yıllık veriler üzerinden D8 ülkesi için panel veri analizi ile Stata 15 programı ile araştırılmıştır. Çalışmadan elde edilen bulgularda; ekonomik büyüme ve sağlık harcamaları arasında çift yönlü bir nedensellik ilişkisi tespit edilmiştir.
CONCEPTUALIZING THE MULTI-DIMENSIONAL NATURE OF FOLK PRACTICE FROM EXAMPLES
Authors: M. Ramakrishnan , Sahoo Subhashree
Published: May 2022

Folklore is a dynamic process and it appropriates the changes in society while simultaneously retaining the elements of tradition and the past to ascertain its continuity of tradition and contemporary relevance. Considering folk practices, the earlier studies had encountered the stereotypical notions constructed around the folklore materials and folklore processes. And some of these notions implied the characteristics of folk practices as traditional, rurality, outdatedness, superstitious, archaic, static, not contemporary, and, to the extent, as irrational. Thus, the later studies on folk practices had to prove the role of folklore in explicating the complex relationship humans have with the natu1re, cosmos and supernatural on the one hand and in contemplating the reflections of their creativity, unconsciousness and their cognitive encounters in their socio-cultural life on the other hand. However, there are two striking features, namely, anonymity and community representation, that make folklore a more individual creation with community ownership and it facilitates the study of folklore folk practices as a first step towards understanding the dimensions of community life. Therefore, while representing the ethos of a community, folklore and folk practices show inclusiveness and accommodativeness by providing either intersection between different communities or by identifying points of convergence or divergence. By taking a few examples from the Santal community of Odisha, this article emphasizes the point that folk practices are rich and meaningful sources that play a significant role in understanding the community life by relating them with “cognition and values” (Dundes 1975:xi-xii) and also by making us realize how they “bring unconscious content into consciousness” (1975:xi)

Published: May 2022

This paper presents the conducted assessment of noise immunity of the request signal transmission channel and response channel for flight information of secondary radar systems as part of aircraft responders. The considered system is an open single-channel queuing system with refusing due to the action in the request channel of intentional and unintentional correlated and uncorrelated (intra-system) interference and ground-based receivers that receive, process and decode flight information in the presence of fluctuation and intra-system interference in the receiving channel. The results of assessing the noise immunity of the aircraft responder in the form of the aircraft responder’s readiness factor under the action of internal and deliberate interference are given. It is shown that the principle of constructing an aircraft responder and the principle of servicing request signals and transmitting flight information do not allow ensuring acceptable probabilities of obtaining flight data at ground control points.
Viaje a la Patagonia Austral: reflexiones en torno al buen gusto y la necesidad de consolidar las fronteras frente a la vecindad amenazante en la prosa de Francisco Pascasio Moreno
Authors: Di Renzo Cristian Andrés
Published: May 2022

En el presente artículo, analizaremos algunos aspectos acerca de la célebre obra Viaje a la Patagonia Austral emprendido bajo los auspicios del Gobierno Nacional (1876-1877) de Francisco Pascacio Moreno. Específicamente, centraremos nuestra atención sobre aquellas concepciones que den cuenta sobre el buen gusto en la lógica de civilización-barbarie. Asimismo, consideramos tales concepciones dentro del contexto histórico de la consolidación de las fronteras nacionales motivadas, a su vez, por la existencia de una potencial vecindad amenazante. Como evidenciaremos, las fronteras demarcadas dentro de la comunidad imaginada que encarnaba la civilización, actuaron como un parámetro mediante el cual el naturalista argentino realizó sus descripciones.
Notas para un estudio sobre la importancia de los viajes de intelectuales en la constitución del pensamiento y la cultura argentina: Victoria Ocampo como pretexto (1916-1931)
Authors: Urquijo Reguera Mariana
Published: May 2022

Los viajes fueron una herramienta central en el desarrollo de la cultura tanto en Europa como en América en el periodo que nos hemos propuesto indagar (1916-1931) a través de la figura de Victoria Ocampo como pretexto ya que posibilita generar un hilo de estudio y narrativo para entender la complejidad de los viajes, su dimensión material, su impacto en la biografía de los viajeros, en los lugares visitados y en los debates que generaron y propiciaron.
Para ello se han elegido tres ejemplos emblemáticos: el del filósofo español José Ortega y Gasset a Argentina, el del poeta hindú Rabindranath Tagore y el del pensador alemán, el conde de Keyserling. La elección de la perspectiva de Ocampo posibilita relacionar a estos personajes entre sí y con los debates de la época en Argentina y Europa. Todo ello permite dar cuenta de un campo de investigación poco explorado en el que este artículo se presenta como un esquema de trabajo y análisis filosófico para futuros trabajos.

ABSTRAKDosa yang telah dilakukan oleh Adam dan Hawa, tidak hanya berdampak pada diri mereka sendiri,akan tetapi, dosa itu juga telah menjalar kepada keturunan mereka bahkan terhadap dunia. Bukan hanya relasi antara manusia dengan Allah yang telah rusak, tetapi relasi manusia dengan sesamanya (Kej 4:1-6),dan relasi dengan dirinya sendiri (Rom 7:19) juga telah rusak karena dosa.Adapun jenis penelitian yang di pakai ke penelitian ini ialah penelitian kualitatif. Yang menurut Sugiyono menetode penelitian yang kualitatif semacam jenis penelitian yang biasa digunakan dalam meneliti pada situasi objek yang bersifat alamiah. Metode penelitian kualitatif berlandaskan pada objek sebagai sebuah hal yang realitas yang menekankan pada keluasan informasi.Secara Etimologi, Kata Dosa berasal dari bahasa Ibrani “ Khatta’t, pesya’ra, dan awon” yang berarti pelanggaran, pemberontakan dan kesalahan, dan dari bahasa Yunani“hamartia, parabasis, adikia, anomia, asebeia, dan paraptoma” yang berarti tidak kena sasaran,pelanggaran,kejahatan,durhaka,kefasikan, dan kesalahan. Jadi singkatnya, dosa dapat diartikan sebagai perbuatan manusia dalam segala macam bentuk, yang selalu ditujukan kepada Allah.

Estimating the human equivalent weight by applying the quarter-power law of allometry to humanity
Authors: GANIO-MEGO Joe
Published: May 2022

In the long term, the relation between the GDP PC and LEB can be approximated with an allometric function of 1/4 exponent.For many species, LEB can be approximated by an allometric function of 1/4 power of body mass.There is a linear relation between edible energy intake (food) and body mass.Edible energy is a form of “negentropy”. Also, if calculated at PPP in Intl Dollars, GDP PC can be considered a form of negentropy.Edible energy is meant to feed the molecular aggregation of a living organism.If we define a hybrid living organism as a living molecular and material aggregation, then we can say that GDP PC is meant to feed the hybrid living organism. It is, therefore, not far fetched to conclude that GDP PC is an analogy of body mass.In the case of the human species, we know the body mass weight, the life expectancy and the GDP PC under prehistorical (pre-technological) conditions. In the case of the human species, we also know the body mass weight, the life expectancy and the GDP PC under current conditions. By inserting those data into the allometric quarter-power law function of body mass and the corresponding Preston-curve function of GDP PC, it can be found that the contemporary equivalent body mass of the year 2020 CE human is about 4.7 tons.Hence modern humans are a hybrid aggregation of molecules and material things, with 1.4% molecular aggregation in weight and 98.6 % material aggregation in weight.

Penulisan ini mengungkapkan Pelayanan Diaken dari Perspektif Teologi Paulus dan implementasinnya bagi Gereja Toraja Jemaat Rantemario. Artikel ini mengkaji tentang kemendarian Paulus sebagai pemberita injil yang hidup. Rasul Paulus sebagai rasul bagi orang-orang non-yahudi memiliki keahlian khusus dalam membuat tanda dalam menjadikan sebagai penopang pendanaan sehingga dapat membuat kelangsungan pemberitaan injil. Ia tidak ingin memberatkan jemaat yang ia layani dalam pandangan pemberitaan injil. Keahlian ia miliki digunakan dengan semaksimal mungkin untuk menopangnnya dalam pelayanan. Sebagai Rasul ia tidak malu untuk berterus terang akan apa yang sedang di kerjakan yaitu sebagai pembuat tanda. Tujuan utamannya adalam keahlian membuat tanda yang di pakainnya sebagai jembatan untuk pemberitaan injil. Dengan demikian setidaknnya ada dua hal yang penting di dapatkan dari topik ini yaitu pertama, kemenderian dana sebagai penginjil, dan kedua, keahlian sebagai jembatan penginjilaan.

Development of a machine learning approach for local-scale ozone and PM2.5 forecasting: Application to multiple AQS sites in the Pacific Northwest
Authors: Fan Kai , Dhammapala Ranil , Harrington Kyle , Lamb Brian , Lee Yunha
Published: May 2022

A machine learning (ML) based modeling framework has been successfully used to provide operational forecasts of O3 at Kennewick, WA. This paper shows its performance when applied to other observation locations to predict O3 and PM2.5 concentrations. The 10-time, 10-fold cross-validation method was used to evaluate the model performance in the Pacific Northwest (PNW). Similar to Kennewick, ML1 captures more high-O3 events, but also generates more false alarms, and the accuracy of ML2 is better (R2 = 0.79), especially for low-O3 events. Compared to AIRPACT, the combined modeling framework reduces the normalized mean bias (NMB) from 7.6% to 2.6%. In terms of Air Quality Index (AQI) forecasts, improvements occur for each AQI level which reflects more accurate O3 predictions and better capture of more high-O3 events. For PM2.5, ML1 and ML2 demonstrate similar capabilities to predict high-PM2.5 events and ML2 keeps its accuracy for low-PM2.5 predictions, so there is no need to combine the two methods. During the evaluation period, AIRPACT under-predicts the wildfire season PM2.5 concentrations in the PNW (NMB = -27%) and over-predicts at some sites in the cold season up to 200%, while ML2 has a lower NMB in both seasons (NMB = 7.9% in the wildfire season and 2.2% in the cold season) and correctly captures more high-PM2.5 events. The ML modeling framework is now operational for forecasts of O3 and PM2.5 at over 100 observation sites in the PNW.
An evolutionary contractualist theory of morality
Authors: André Jean-Baptiste , Fitouchi Léo , Debove Stephane , Baumard Nicolas
Published: May 2022

Our goal in this paper is to use an evolutionary approach to explain the existence and design features of human moral cognition. Our premise is that humans are under selection to be good cooperative investments. Hence, they face a trade-off between maximizing the immediate gains of each social interaction and maximizing its long-term reputational effects. In a 2-player game, we show, under simplifying assumptions, that this trade- off leads individuals to maximize the generalized Nash product in evolutionary equilibrium, i.e., to behave according to the generalized Nash bargaining solution. From this result we derive the theoretical proposition that morality is a calculator of this bargaining solution. We then describe the general consequences of this approach: (i) everyone in a social interaction deserves to receive a net benefit, (ii) people should act in a way that would maximize social welfare if everyone acted in the same way, (iii) all domains of social behavior can be moralized, (iv) moral duties can appear both principled and non-contractual, and (v) morality should depend on context. We then apply the approach to some of the most important areas of social life, and show that it allows us to explain with a single logic the entire set of what are generally considered to be distinct moral domains. Finally, we discuss the relationship between this account of morality and other evolutionary accounts of morality and cooperation.
Using the experience sampling method to support clinical practice: An illustration with problematic cannabis use
Authors: Piccirillo Marilyn , Enkema Matthew , Foster Katherine T.
Published: May 2022

Objective: The experience sampling method (ESM) has been frequently used in clinical research; however, the low translational uptake of ESM in clinical practice may be due to challenges with interpreting individual-level trends at granular intervals. We provide an illustrative example of how ESM can be leveraged to generate personalized cognitive-behavioral strategies for problematic cannabis use. Method: We conducted a descriptive case series analysis using ESM data from 30 individuals reporting on problematic cannabis use, craving, affect, and coping four times daily for 16-days (t = 64, T = 1,920). Results: Analyzing ESM data using descriptive statistics and visualizations from individuals with similar clinical and demographic profiles supported a diverse array of personalized clinical insights and recommendations for each case. These recommendations included psychoeducation regarding affect- and boredom-regulation strategies, functional analyses of occasions during which cannabis was not used, and discussions on how cannabis use intersects with one’s personal values. Conclusion: While many clinicians utilize measurement-based care, barriers have limited the incorporation of ESM towards personalized, data-informed approaches to treatment. We provide an illustrative example of how ESM data can be used to generate actionable treatment strategies for problematic cannabis use and highlight continued challenges with interpreting dense time-series data.Keywords: measurement-based care; ambulatory assessment; time-series data; cannabis use; clinical recommendations
Operationalization and generalization in experimental psychology: A plea for bold claims
Authors: Pfister Roland
Published: May 2022

The rise of scientific psychology has been tied closely to the adoption of experimental techniques in the study of human cognition and behavior. Experiments provide an elegant and rigorous tool to test mechanistic theories and they do so by distilling a theoretically relevant idea into an observable measure as part of a behavioral task – a process commonly dubbed as operationalization. I argue that modern experimental psychology is plagued by a continued trend towards overlooking the critical role of such operationalization. This neglect manifests in two seemingly opposing ways, either in research that jumps to inadequate conclusions by playing down the role of tasks in generating the research findings or, conversely, in research that is mainly focused on examining tasks (“paradigms”) for their own sake rather than testing theoretical ideas. This state of affairs can be rectified by re-embracing the power of explicit, theory-driven operationalization as I discuss in general terms as well as applied to the exemplary case of research on rule-violation behavior. Shifting focus back to how a theoretical idea is operationalized in a given research program will help to render experimental research in psychology methodologically sound while at the same time being able to provide generalizable findings.
Daughters, Unwin & Rees (2022) The psychological impact of adult-onset craniopharyngioma: The experience of patients and clinicians
Authors: Daughters Katie , Unwin Katy , Rees Aled
Published: May 2022

Individuals who experience social and emotional difficulties struggle to maintain successful social relationships and incur an increased risk of developing mood disorders. These, in turn, have a significant impact on psychological and physical wellbeing. A small number of medical studies suggest that patients with adult-onset craniopharyngioma (AoC) report poorer quality of life, however, no in-depth psychological research has been carried out. The present study aimed to capture a rich understanding of whether patients with AoC experience a psychological impact from their diagnosis and whether psychological factors may contribute to a poorer quality of life. Both patients with AoC and clinicians with experience of working with patients with AoC were invited to take part in a semi-structured interview. Participants were recruited from three geographically disperse National Health Service (NHS) units across the United Kingdom (UK). Eight patients and 10 clinicians took part in the study. Interviews were analysed using inductive thematic analysis. Three themes, with multiple subthemes, were identified: 1) Patients experience psychological impacts of AoC; 2) Patients also experience common physical symptoms; and 3) Further research into the psychological impacts of AoC is necessary and interesting. Patients and clinicians recognised significant psychological impact as a result of AoC, and these impacts contributed to overall poorer quality of life. Crucially, both parties also felt that further research into psychological impact of AoC was both interesting and useful.

Creativity research often relies on human raters to judge the novelty of participants’ responses on open-ended tasks, such as the Alternate Uses Task (AUT). Albeit useful, manual ratings are subjective and labor intensive. To address these limitations, researchers increasingly use automatic scoring methods based on a natural language processing technique for quantifying the semantic distance between words. However, many methodological choices remain open on how to obtain semantic distance scores for ideas, which can significantly impact reliability and validity. In this project, we propose a new semantic distance-based method, maximum associative distance (MAD), for assessing response novelty in AUT. Within a response, MAD uses the semantic distance of the word that is maximally remote from the prompt word to reflect response novelty. We compare the results from MAD with other competing semantic distance-based methods, including element-wise-multiplication—a commonly used compositional model—across three published datasets including a total of 447 participants. We found MAD to be more strongly correlated with human creativity ratings than the competing methods. In addition, MAD scores reliably predict external measures such as openness to experience. We further explored how idea elaboration affects the performance of various scoring methods and found that MAD is closely aligned with human raters in processing multi-word responses. The MAD method thus improves the psychometrics of semantic distance for automatic creativity assessment, and it provides clues about what human raters find creative about ideas.

Alstonia scholaris contains flavonoids, tannins, triterpenoids, resins and alkaloids. Alkaloid compounds, tannins and flavonoids of plant origin can inhibit weed growth. Alkaloid compounds, tannins and flavonoids work by suppressing the hormone auxin and the hormone gibberelin so that weed growth is inhibited. This study aims to determine the potential of Alstonia scholaris leaves in inhibiting the growth of weed Cyperus rotundus. The inhibition of Cyperus rotundus growth can be seen from changes in leaf color/population phytotoxicity, number of leaves, and height of Cyperus rotundus. The research used Cyperus rotundus leaves which were mashed into flour and then extracted by macerating with alcohol 96% . The results of the extract of Cyperus rotundus leaf flour consisting of a concentration of 0 g/l (control), 25 g/l, 50 g/l, 75 g/l, and 100 g/l were applied to Cyperus rotundus. Pure extracts are given with different concentrations to determine the concentration that is effective in suppressing the growth of Cyperus rotundus. Vegetable herbicides of Cyperus rotundus leaves with a concentration of 50 g/l became the solution to control the enchanted grass weeds that are environmentally friendly without using synthetic herbicides. With the results of phytotoxicity P2= 40.00%, wet weight P2= 1.53 g, and dry weight P2= 0.91 g.

Bamboo is one of the non-timber natural forest products that has the potential to be used as raw material for wood substitutes because bamboo has many advantages. If for wood with high durability, it takes time from planting seedlings to be ready for harvest is 30-40 years and even then after cutting down the seeds must be planted again, but bamboo takes up to 4-5 years to be ready to be harvested. The problem that arises is that bamboo has a limited dimension so that it requires lamination technology that can shape bamboo into a dimensioned material according to construction needs. Lamination technology is an alternative way of processing bamboo that is relevant to achieving the expected goals. Lamination can make the strength of betung bamboo far higher than solid wood blocks. Tests carried out by physical and mechanical tests of betung bamboo lamination using JAS 234: 2003. Testing the physical properties of the betung bamboo includes a wood density test for moisture content testing, and thickness swelling. The mechanical properties of the betung bamboo include the modulus of rupture and modulus of elasticity tests. The lamination test has variations in the number of layers A1 (3 layers), A2 (5 layers), and A3 (7 layers) with 3 replications each. Betung bamboo density obtained an average of 0.316 gr/cm3 to 0.453 gr/cm3, the average moisture content of betung bamboo was 11.386% to 12.444%, and the average thickness swelling test was 0.240% to 0.293%. Modulus of rupture test is 210,160 kg/cm2 to 925,963 kg/cm2, and the modulus of elasticity test shows an average of 0.916 kg/cm2 to 925,963 kg/cm2. The physical properties of the betung bamboo (Dendrocalamus asper) meet the JAS 234: 2003 standard is the moisture content, for the density and thickness swelling bamboo betung lamination is not required in the JAS 234: 2003 standard. The mechanical properties of betung bamboo laminate for MOE values are equivalent to wood strength classes II-IV and MOR are equivalent to wood strength classes V
