Working for fun? The impact of employment in the arts sector on wellbeing
Authors: Benison Thomas , Le Trinh , Grimes Arthur
Published: October 2023

Despite the prospect of adverse financial and employment outcomes, the labour market for arts workers is often characterised with an excess supply of workers. Several theories have been proposed to explain this puzzle. In recent years one theory that has gained prominence is that employment in the arts provides workers with high wellbeing, which may compensate them for the low pay they receive. Using New Zealand Census and household survey data, this study finds that on average arts workers earn about 20% less than non-arts workers, however about half to two thirds of this pay gap can be explained by differences in observed characteristics between the two groups. While causality is not formally proved, we provide indirect evidence that employment in the arts sector has a positive impact on wellbeing. This additional wellbeing may be considered psychic income, which could be one reason why some people stay in the arts labour market despite the prospect of lower pay.

Published: October 2023

Desde o período de escravização das/os negras/os que foram sequestradas/os da África para o nosso país, o Brasil tem se especializado nas estratégias de contenção e de controle da população negra brasileira. A forma contemporânea se traduz no encarceramento em massa de negros e negras, especialmente as/os jovens, pobres e periféricas/os. Como nos ilustra muito bem o cantor e compositor Marcelo Yuca (1994) na canção “Todo camburão tem um pouco de navio negreiro”, a forma contemporânea dessa vigilância ostensiva direcionada quase que exclusivamente aos negros e negras desse país. Diz a letra da música: “quem segurava com força a chibata agora usa farda”, ou seja, o policial é a figura contemporânea do feitor e o Estado a do senhor dos negros e das negras escravizadas/os. As prisões brasileiras são as figuras contemporâneas que nos remetem às senzalas do Brasil escravizador.

Published: October 2023

Abstract. A number of forms of social care have become church traditions throughout time. On the other hand, many have predicted that in 2023 the world, including Indonesia, will experience quite heavy economic pressure. In a situation like this, what if the church also experiences a crisis, either financially or in terms of other resources? Can the tradition of social care be annulled? To answer this question, this paper conducted argumentation analysis and social analysis in interpreting 1 Timothy 5:3-16. This study showed that Paul reminded the congregation leader (Timothy), that despite limited conditions, he must not annul this tradition, but in its implementation it must be making sense and educating. Thus, it can be concluded that the church in Indonesia needs to apply making sense and educating principles in practicing a number of social care traditions.Abstrak. Sejumlah bentuk kepedulian sosial telah menjadi tradisi gereja di sepanjang masa. Pada sisi lain, sejumlah pihak memprediksi bahwa pada 2023 dunia, termasuk Indonesia, akan mengalami tekanan ekonomi yang cukup berat. Dalam situasi seperti ini, bagaimana jika gereja ternyata juga mengalami krisis, baik krisis dalam hal keuangan maupun dalam hal sumber daya yang lain? Dapatkah tradisi kepedulian sosial itu dianulir? Untuk menjawab pertanyaan tersebut, tulisan ini menggunakan analisis argumentasi dan analisis sosial dalam memaknai 1 Timotius 5:3-16 ini. Kajian ini menunjukkan bahwa Paulus mengingatkan pemimpin jemaat (Timotius) meskipun kondisi keterbatasan tidak boleh menganulir tradisi tersebut, tetapi dalam pelaksanaannya haruslah rasional dan mendidik. Dengan demikian dapat disimpulkan, gereja di Indonesia perlu menerapkan prinsip rasional dan mendidik dalam mempraktikkan sejumlah tradisi kepedulian sosial.

Comparing Predicted Deposit Velocities with Operating Velocities in Four Long Distance Concentrate Pipelines
Authors:   Slurry Systems Engineering Pty Ltd PO Box 2316, Marmion, Perth, Western Australia, Thomas Allan
Published: October 2023

Predicted deposit velocities have been compared with operating velocities in four concentrate pipelines: The 155 km Ok Tedi copper concentrate pipeline in PNG, the 304 km Century zinc/lead concentrate pipeline in Australia, the 301 km Antamina copper/zinc concentrate pipeline in Peru and the 62 km Whyalla iron concentrate (magnetite) pipeline in Australia. Concentrate slurry properties are listed and methods used to predict the deposit velocity noted and referenced. Comparing predicted deposit velocities with operating velocities allows the velocity margin for each pipeline to be compared. Velocity margins range from 0.25 m/s to 0.86 m/s and reasons for the differences are discussed. It is concluded that, in the four operating pipelines, the deposit velocity is generally determined by viscous sub-layer deposition rather than laminar transition deposition.

The effect of temperature on the flow curves of both un-flocculated and flocculated kaolin slurries at 40% by mass concentration over the temperature range of 21ºC and 89ºC has been studied previously (Zengeni et al., 2019). A co-axial cylinder viscometer was used to make flow curve measurements over the shear rate range of 10 to 300 s-1. These data have been re-analysed using the power law model and the effect of Brownian motion on determining the rheological behaviour assessed. The slurry relative viscosity has been found to correlate well with a dimensionless quantity, the Colloid number

Theoretical expressions have previously obtained for the statistics of the residence time distribution of particles falling individually in a stationary, Newtonian liquid. The dispersion in the residence or sedimentation time arises both from the size dispersion that may be present in the particles and also because of fluctuations in the axial velocity of the particles about the time-invariant terminal velocity. Such fluctuations are inevitable, except at extremely low Reynolds numbers. The size dispersion is represented by the Log-Normal distribution, as is customary for many particle populations. The erratic nature of particle velocity is represented by a dispersion coefficient and then incorporated into a corresponding Peclet number. The dispersion coefficient reflects both the level of fluctuation in velocity and the representative time-scale of the velocity fluctuation. In addition to residence time distribution, the level of correlation or dependence between particle size and particle residence time can be determined by this method. The theoretical work was previously validated using glass and plastic particles falling in glycerol and water, characterized by low (Re ≈ 1) and high (Re ≈ 1000) Reynolds numbers, respectively. For this paper, new experiments were conducted examining the fall of expanded polystyrene particles with a range of sizes in air. Experiments were carried out with single particle falls and batch (groups of particles) falls. In addition to using different fluids and particles to the previous work, the tests were conducted over a wider range of Reynolds numbers. Results demonstrated that the theory was still valid for these new experiments. Dispersion in residence time and the relationship between particle size and its residence time were predicted with reasonably good accuracy.

In Canada’s oil sands industry, the processing and storage of fluid fine tailings is important because it directly impacts land usage and reclamation, water and thermal energy requirements as well as environmental stewardship and mine sustainability. A key technology used for this purpose is inline flocculation, wherein existing inventories of fluid fine tailings are withdrawn from tailings storage facilities and mixed with polymer flocculants. These flocculated tailings can be then sent through additional process stages (e.g. evaporation, centrifugation, filtration) to promote dewatering and improved geotechnical characteristics of the resulting deposits. The polymer type, dosage and inline mixing conditions primarily dictate the efficacy of the inline flocculation process. Presently, numerous measurements are taken to establish flocculation performance. Some of these require samples to be collected and analyzed, meaning that such measurements cannot be used for real-time process control. Others, such as online FBRM (focus beam reflectance measurement), can be used for real-time process control but are often challenging and expensive to deploy in a commercial operation. The present study represents a preliminary assessment of the use of pressure measurements to monitor flocculation performance using a pilot-scale inline flocculation rig. Tests were conducted at different flow rates and polymer injection rates/concentrations. The test rig was fitted with 4 differential pressure sensors positioned at different axial locations. The pressure gradients measured just downstream of the inline mixer were primarily dictated by the production, and subsequent break-up, of the shear-sensitive floc structures and thus were highly sensitive to changes in polymer dosage at any given fluid tailings feed rate. A relationship among conventional performance metrics (e.g. floc size from FBRM) and maximum pressure gradient measured downstream of the mixer was observed, i.e. the same optimal polymer dosage was indicated by conventional measures and peak pressure gradient.

Published: October 2023

A slurry pipeline is a specially designed pipeline used to transport the mining tailings and waste of ores like iron or coal over long distances. A commercially tested solution for the transport of iron ore slurry over the farthest distances in a pipeline includes various parametric checks. For the slurry to move, consuming optimal power in the pipe while maintaining the required velocity, it is important to keep some parameters within the desired limits, the most important of which is the pressure drop in the slurry pipeline. Pilot plant loop tests were conducted with iron ore slurry at high concentration (72% by weight or 32.7% by volume). The flow velocities were set in the range of 1.5 m/s to 4 m/s and the pressure drop per unit length was measured for each flow velocity using the U-tube differential manometer installed in the setup. The pressure drop values were also calculated using standard equations available in the literature and deviations up to 221% from experimental values were observed. Alternatively, a CFD model was developed using Ansys Fluent© and validated using the experimental results. This was a first attempt to predict such flows, and further tests are needed to confirm the initial results.

Deep-sea mineral resources are becoming an essential guarantee for humankind’s future socioeconomic sustainable development due to the decrease in terrestrial mineral resources. Collection devices, as vital components of deep-sea mining systems, need to address the efficiency of collection and the environmental disturbances caused by mining activities. The present study investigated the influence of the angle of jets and the radii of a convex wall on the flow field inside the Coandǎ-effect-based collection device to optimize the collection device using a numerical approach. The results indicated: (1) the increase of the angle of jets and radii of a convex wall of the collection device improved flow field uniformity, and the kinetic energy of flow concentrated in the bottom region. The higher mobile speed of the collection device induced a greater Coandǎeffect beneath the convex wall. The internal flow field remained relatively stable when the device was at a speed of 0.5 m/s. (2) the angles of jets and the radii of the convex wall had a significant correlation with the lift and drag force on the nodule. The lift force on the nodule increased when a larger angle of jets or smaller radii of the convex wall occurred in the present study. (3) after analysing the transportation path of nodule particles in stages of separating, lifting, and carrying, it was found that the collection device accurately captured the nodules into the inlet in the scenarios that the collection device had a height of 80 mm above the seafloor and an input jet with an angle of 45°meanwhile the convex wall had a radius of 350 mm with the collection device movement at a speed of 0.5 m/s. This study provides important guidelines for the design and development of deepsea polymetallic nodule collection devices.

Green and Safe “By Design”: A Conceptual Tool to Avoid Hazardous Substances in Early Phases of Product Development
Authors:   Polytechnic of Bari, Rocco Claudio
Published: October 2023

Sustainability has to be managed in order to guarantee health, social equity, resource optimization and economic activities and this awareness is grown considerably. At the same time, this consciousness leads us to consider sustainability also as a social and a business driver on the economic side and a great opportunity by an environmental point of view. Further, according to several regulations, producers are responsible of their devices in terms of environmental pollution, from production and market launch to disposal activities when they become unusable. This fact changes the role of designers, which becomes wider in a multidisciplinary context. For this reason, this paper proposes an approach that supports designers during the development of more sustainable products with the aim to reduce the amount of hazardous substances (according to European RoHS regulations) and it allows firms and academic R&D departments to reduce risks of a missing compliance. The approach is structured according to a flowchart that addresses designers to more suitable product solutions in terms of environmental impact. The methodology applied to the case studies, in fact, show that an early assessment in first design phases allows developers to have safer and more sustainable product prototypes and its application can be proposed also during design courses in an educational context.

This paper proposes a fuzzy logic-based tuning model (FLTM) for daylight-linked control of the lighting system in an office room. The proposed FLTM considered a new method of dimming levels of light-emitting diode (LED) luminaires updating process to improve the performance of the developed fuzzy logic controller (FLC) in terms of energy consumption and visual comfort metric and, at the same time, fully complies with the European Standard EN 12464-1. The artificial lighting system and daylight simulation were carried out using DIALux to model artificial lighting and daylight illuminance levels matrices. The proposed FLTM was developed and simulated using MATLAB and validated and compared with other controllers, including developed FLC and artificial neural network (ANN) based control. The simulation results showed that the proposed FLTM successfully improved the performance of developed FLC in terms of a fully satisfied visual comfort set-point. It also attained higher energy savings of 2% than ANN and achieved the closest to preset visual comfort compared with other controllers. Moreover, the proposed method consumes less computational effort, and it is easy to integrate with developed FLC and daylight-linked control of the lighting system.

There are three types of insulators, namely glass, ceramic, and polymer. Although polymers have hydrophobic properties that make them superior to other materials. However, in its application, ceramic and glass insulators are still used because they are cheaper. Environmental conditions around the work location of the insulator greatly affect its performance. Areas with high levels of pollution will result in the insulator being damaged quickly. The effect of seawater and fly-ash contaminants on the three types of insulators is discussed in this study. Experimental approaches and FEM-based simulations have been carried out. Pollution levels in seawater contaminants were standardized using ESDD. Meanwhile, the level of pollution in fly-ash contaminants is standardized using NSDD. Simulations and experiments were carried out at four levels of contamination, namely light, medium, heavy and very heavy. Then the simulation and test results are compared. The greater the ESDD and NSDD values, the greater the leakage current.

This paper focused on the optimal operation of the hybrid energy resources in the off-grid state considering energy storage participation. The hybrid energy resources consist of wind turbine (WT), photovoltaic (PV), diesel generator (DG), and energy storage system for supplying energy to DC and AC load demand with maximum reliability. The operation of the proposed energy system based on energy control and energy optimization is modeled. The energy optimization and energy control are implemented by heuristic and nonlinear quadratic programming approaches via optimal power flow on the resources side. The energy control is done based on the weight sum method in different operation states of the system. Also, the impact of the energy storage system on the hybrid energy resources is considered as backup resources. The energy control modeling is implemented via mathematical simulation and numerical analysis in the two operation states in the summer and winter seasons for verifying the proposed approaches. Finally, the results of the energy control show optimal states of the energy system in supplying demand with considering the energy storage system.
Cutting On Existing Bonded Post-Tensioned Slabs: Safety Precautions, Procedures and Execution

Published: October 2023

Post-formed cut-off or cutting of the post-tensioned slabs is a common practice during post-tensioning work. However, cutting on existing post-tensioned slabs must be done carefully to avoid severe damage to the building. The measurements during the design review are critical in considerations of post-cutting conditions, variations between shop drawings and site, possible grouting failure and excessive deformation. This paper presents a successfully execution of cutting operations on bonded post-tensioned slabs without compromising the structural strength and serviceability. There are procedures and requirements that need to be considered prior to cutting at the design stage, prior to cutting at the site and at slab cutting stage. The safety precautions are necessary for unintentional scenarios that require immediate action. Cutting the slab creates potential hazards. It was found that the grouting material plays an important role not only in solidifying the concrete but also in forming a secondary anchorage mechanism. Therefore, selection of suitable grouting material should be based on the dimension of the locking area. In contrast to unbonded post-tensioned slabs, bonded post-tensioned slabs do not require de-tensioning and re-tensioning.
Kıraatlerin İştihârında Sosyo-Kültürel Ortam ve Siyâsî İlişkilerin Rolü

İhtiyâr kelimesi lugatte “seçmek”, “yeğlemek”, ”önde tutmak”, “tercih etmek”, “özel kılmak” gibi anlamlara gelmektedir. Bu kavram kıraat ilmi için vecih ve rivayetler arasından birini tercihte bulunmayı ifade etmektedir. Bu tercih işlemi yapılırken isnâd, resm-i Mushaf, Arap dili kaideleri ve iştihâr gibi şartlar gözetilmektedir. Sahabe döneminde kıraatlerden ihtiyârda bulunulup bulunulmadığı ve sonraki dönemlerde neden kıraatler arasından ihtiyârda bulunulduğu gibi konular önemli görülmektedir. Kurrâ çoğalıp beldelere dağılınca, kıraat farklılıklarına dair birikim bu bölgelerde de yayıldı. Sonraki nesiller arasında tilavette yetkin, rivayet ve dirayet yönüyle şöhret bulmuş kimseler mevcut bulunduğu gibi bu nitelikleri taşımayanlar da vardı. Bu durum iki zümre arasındaki ihtilafları arttırdı. Bunu önlemek isteyen âlimler kıraatlerin sahih ya da sakim olanının ayrımına dair olan kaideleri tespit edip bu kaideler ışığında kıraatler arasında ihtiyârda bulundular. Böylelikle onlar, kıraatler konusunda hak ile batıl olanı, meşhur ile şâzz olanı, mütevatir ile ahâd olanı belli etmiş ve kıraatlerin senetlerini kaynağına dayandırmışlardır.
Kıraat tercihinin devam etmesi ve ihtiyârların sayısal olarak artmasıyla kıraatleri zabt etme zorluğu ortaya çıkmış, bu durum ihtiyârları sınırlandırmayı getirmiştir. Kıraatlerin sınırlandırılmasında ihtiyâr için bir gerekçe sayılan iştihârın, büyük etkisi görülmektedir. İştihâr, bir kıraatin yaygınlık kazanarak şöhret bulması anlamına gelir.
Çalışmanın amacı ihtiyâr ile iştihâr arasındaki bağlantıyı ortaya koyarak siyasi ilişkilerin kıraatlerin iştihârındaki rolünü ortaya koymayı amaçlamaktadır. Bir kıraatin iştihârı elde ederek yaygınlık kazanması iç etkenler ve dış etkenler olmak üzere iki farklı şekilde ele alınmaktadır. İç etkenler tercîh edilen kıraatte ve kıraati nakleden kârîde bulunan özellikler iken, dış etkenler sosyo-kültürel ortam ve siyâsî ilişkiler gibi faktörlerdir. Bu çalışmada iştihârda etkili olan iç etkenlerin neler olduğu belirtilip dış etkenler üzerinde durulmuştur. Çalışmada dış etken olarak nitelendirilen lahnî okumaların, ilim merkezi olan şehirlerin, fıkhî mezheplerin ve siyâsî otoritelerin kıraatlerin iştihârında ne tür etkileri olduğu doküman analizi yöntemiyle incelenmiştir. Bu etkenler arasından ilim merkezleri ve siyâsî otoritelerin bir kıraatin iştihâr bulmasında daha önemli bir etkiye sahip olduğu sonucuna ulaşılmıştır.
p53-regulated Xist modulation features Tfdp1 activation.
Authors: Mamoor Shahan
Published: October 2023

We recently described a sex-specific transcriptional regulation mechanism, found in physiologically relevant settings in breast cancer cells in vitro and in cells of the embryo in mice and humans, wherein mutation or loss of the p53 tumor suppressor results in transcriptional perturbation of the non-coding RNA that functions in X-inactivation, Xist, with this transcriptional change being among the most quantitatively substantial changes transcriptome-wide - naturally, in the presence of p53 mutation, or experimentally following deletion of p53 (1). Here, we studied p53 wild-type and p53 mutant breast cancer cell lines as well as Xist-positive and Xist-negative human embryonic stem cell clones (2, 3) to understand the transcriptional consequences of Xist up-regulation following loss of p53 tumor suppression in development and transformation. We reveal activation of Tfdp1 as a transcriptional feature of Xist modulation following impairment (disability) of p53 (4-6).
E2F1 is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: October 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that E2F transcription factor 1, encoded by E2F1, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. E2F1 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of E2F1 in primary tumors was correlated with patient overall, distant metastasis-free and recurrence-free survival. Modulation of E2F1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.
Implementing Web Applications in English as a Foreign Language Classrooms to Develop Productive Skills

Published: October 2023

Education has not been immune to the substantial changes brought about by the fast spread of digital technology, multimedia, and social networks over the last several decades. These changes have had a tremendous influence on every facet of our lives. Training was provided to teachers of English in schools and colleges on how to utilize Web 2.0 technologies, in particular a number of mobile applications, to assist their students in improving their language skills. This thesis takes a look at how Web.2 technologies may be used in English for Speakers of Other Languages (ESOL) programs taught in secondary schools with the intention of improving students' ability to communicate orally and in writing. VoiceThread and FlipGrid were the mobile applications that were used for the research study that was carried out. The purpose of the study that will be presented later on as the thesis is to conduct research on the effectiveness of using mobile apps to instruct English to speakers of other languages. The work will focus, more specifically, on the discussion of various techniques that could be helpful for students to improve their English language skills, particularly their ability to speak and write in the language. The work will also focus on the improvement of students' ability to speak and write in the language. In addition to this, the study looks at the potential downsides of using mobile apps in secondary school English lessons.
GANAB is differentially expressed in central nervous system metastasis in human breast cancer.

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that glucosidase II alpha subunit, encoded by GANAB, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. GANAB mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of GANAB in primary tumors was correlated with patient recurrence-free survival. Modulation of GANAB expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that forkhead box D4, encoded by FOXD4, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. FOXD4 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of FOXD4 in primary tumors, however, was not correlated with patient survival outcomes in human breast cancer. Modulation of FOXD4 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Published: October 2023

After seeing an action sequence children and adults tend to copy causally relevant and, morestrikingly, even perceivably unnecessary actions in relation to the given goal. This phenomenon,termed “over-imitation”, has inspired much empirical research in the past decade as well as livelytheoretical debate on its cognitive underpinnings and putative role in the transmission of culturalknowledge. Here, we offer a comprehensive review of the existing literature to date, accom-panied by a table including concise information on 54 published studies testing over-imitation indifferent species, age groups and cultures. We highlight methodological issues related to task andcontext that influence over-imitation rates and that should be carefully considered in study de-signs. We discuss the cognitive and motivational processes underlying and contributing to over-imitation, including normative action parsing, causal reasoning, motives of affiliation and sociallearning as well as their complex interplay. We conclude that despite the apparent irrationality ofover-imitation behavior, recent studies have shown that its performance depends on the specifictask, modeled actions and context variables, suggesting that over-imitation should be con-ceptualized as a contextually flexible and, in fact, a normally highly functional phenomenon.
