Source and Attenuation Properties of the 2012 Moe, Southeastern Australia, Earthquake Sequence

The 19 June 2012 local magnitude ML 5.4 (⁠Mw 5.1) Moe earthquake, which occurred within the Australian stable continental region, was the largest seismic event for the state of Victoria, for more than 30 yr. Seismic networks in the southeast Australian region yielded many high‐quality recordings of the moderate‐magnitude earthquake mainshock and its largest aftershock (⁠ML 4.4 and Mw 4.3) at a range of distances from the epicenter. The source and attenuation characteristics of the earthquake sequence are analyzed. Almost 15,000 felt reports were received following the mainshock, and its ground motions tripped a number of coal‐fired power generators in the region amounting to the loss of, approximately, 1955 MW of generation capacity. The attenuation of macroseismic intensities is shown to mimic the attenuation shape of eastern North America (ENA) models but requires an interevent bias to reduce predicted intensities. Furthermore, instrumental ground‐motion recordings are compared to ground‐motion models (GMMs) considered applicable for the southeastern Australian (SEA) region. Some GMMs developed for ENA and SEA provide reasonable estimates of the recorded ground motions of spectral acceleration within epicentral distances of, approximately, 100 km. The mean Next Generation Attenuation‐East GMM, recently developed for stable ENA, performs relatively poorly for the 2012 Moe earthquake sequence, particularly, for short‐period accelerations. These observations will help inform future seismic hazard assessments for eastern Australia.
Marketing and communicating sustainability through college athletics: the effects of pro-environmental initiatives on the belief-attitude-intention hierarchy

ABSTRACT This study examines the psychological mechanism of consumers’ environmentally responsible behaviors in college sport. The research is guided by a belief-attitude-intention (B-A-I) hierarchy model. The results revealed that consumers who see benefits in a college athletic department’s pro-environmental initiatives (PEIs) have positive attitudes toward the PEIs. These attitudes then drive the consumers’ intentions to engage in environmentally responsible behaviors. The findings of this empirical study confirmed the causal flow of a B-A-I link in a college athletic department’s PEIs. In the hierarchy-of-effects process, belief is a key precursor of action. Attitude appears to function as a mediator between belief and behavioral intention. Practical implications, in terms of communication strategies to strengthen consumers’ beliefs about the benefits of PEIs, are presented. In short, the college athletic department is crucial in the fulfillment of an institutional priority.
The importance of mentorship and collaboration for scientific capacity-building and capacity-sharing: perspectives of African scientists

Long-term goals for capacity-building in Africa centres around building a self-sufficient scientific community, however there is a lack of research on the interactions that are needed to make up a thriving academic community or the steps needed to realise such a goal. Through interviews with researchers supported by a capacity-building initiative, we have characterised their interactions with other scientists and the impact that these have on capacity-building. This has revealed a wide range of interactions that have not been captured by traditional bibliometric studies of collaboration and shown that a substantial amount of intra-African collaboration is taking place. This collaboration allowed the researchers to share capacity with their colleagues and this could provide an alternative to, or supplement, traditional North-South capacity-building. We have shown that this capacity-sharing can enable capacity to spill over from capacity-building programmes to the broader scientific community. Furthermore, researchers are deliberately hastening this capacity-sharing through training or mentoring others outside of their capacity-building initiative, including those from more resource-poor groups. To understand how capacity-building initiatives can harness the power of these interactions, we investigated how interactions between researchers originated, and found that collaborations tended to be formed around pre-existing networks, with researchers collaborating with previous colleagues, or contacts formed through their mentors or consortium activities. Capacity-building organisations could capitalise on this through actions such as expanding mentorship schemes but should also ensure that researchers are not limited to pre-established networks but have exposure to a changing and growing pool of expertise. As interactions continue to move online since the appearance of COVID-19 this will present opportunities for new interaction patterns to develop. This study highlights the need to develop new metrics for collaboration that will take into account these new modes of interaction and the full range of interactions that make up a scientific community.
Tactical factor allocation for multifactor portfolios

ABSTRACT Factor investing comprises selecting the set of factors and the right amount of each factor for investment. While past research provides a better guidance on which factors to invest, deciding the right factor allocation has remained relatively elusive. Motivated by the superior performance provided by the equal-weighted strategy compared to the more sophisticated ones, we choose the former as the baseline or the strategic allocation scheme for factor investing and investigate if improvements can be established. Specifically, exploiting the momentum property exhibited by the factors, we propose a simple tactical factor allocation scheme for the equity-based multifactor portfolios. Empirical results reveal that the proposed tactical factor allocation outperforms the strategic one persistently over time and pervasively across different markets.
Fluorescence properties of humic substances transformed in ectohumus horizons of Podzols affected by alkaline fly‐ash

Lignite burning is still the main source of energy in many countries, generating huge amounts of alkaline residues deposited in dumping sites, which affects the surrounding environment. There are only a few publications dealing with the effects on pH changes of surface horizons, but there are no reports on the impact on other soil properties. The aim of this paper was to characterize the changes occurring in the soil organic matter (SOM) of ectohumus horizons of Podzols located near the dumping site and at the control site. Conventional one‐dimensional, synchronous, and three‐dimensional fluorescence can provided a new information on differences in the structure of humic substances (HS), which are crucial constituents of SOM. Humic acid (HA) and fulvic acid (FA), originally present in the ectohumus horizon, indicated a lower degree of humification, and were characterized by a looser structure, than HS that were extracted from soils affected by fly‐ash. The neutralization of the soil reaction resulting from the deposition of fly‐ash favored the formation of higher humified HS, characterized by a higher concentration of aromatic rings in the core of the molecule and the presence of double conjugated bonds. The fluorescence technique could be applicable to monitor the chemical modification of soils in regions affected by ashes but also all factors changing soil pH. The conducted research has shown that fluorescence spectroscopy can be successfully used as a sensitive technique to characterize qualitatively structures of different organic substances present in terrestrial and aquatic systems.
The Impact of Foreign Direct Investment on Income Inequality in Vietnam

Foreign direct investments (FDI) is an important determinant of economic growth. FDI does not only contribute to the growth and economic development but also affects income through contributing to economic development and the impact on employment and salary structure of developing countries. The aim of this paper is to analyze the impact of FDI on income inequality in Vietnam. This study is the first attempt to examine the impact of FDI on income inequality under the constraints of the institution and education levels. To address the potential endogeneity problem, this study adopts Genernalized Method of Moment (GMM) model to conduct the estimation. A two-step GMM model with robust standard errors is used in the study. Empirical results show that FDI tends to increase income inequality in Vietnam and the existence of a non-linearity relationship between FDI and income inequality is also validated. Moreover, the study finds that the effects of FDI on income inequality are different depending on the level of education and institutions of the host provinces in Vietnam. The results of this study imply that, in order to ensure sustainable development, Vietnam’s policies should focus on improving the quality of economic governance and the administrative reform efforts of the government of the provinces and cities. Besides, policies should focus on increasing investment in public education and improving human capital, which not only can reduce income inequality but also can attract more FDI inflows.
How Personal Experience Affects Perception of and Decisions Related to Climate Change: A Psychological View

The proportion of the world’s population exposed to above-average monthly temperatures has been rising consistently in recent decades and will continue to grow. This and similar trends make it more likely that people will personally experience extreme weather events and seasonal changes related to climate change. A question that follows from this is to what extent experiences may influence climate-related beliefs, attitudes, and the willingness to act. Although research is being done to examine the effects of such experiences, many of these studies have two important shortcomings. First, they propose effects of experiences but remain unclear on the psychological processes that underlie those effects. Second, if they do make assumptions about psychological processes, they do not typically corroborate them with empirical evidence. In other words, a considerable body of research in this field rests on relatively unfounded intuitions. To advance the theoretical understanding of how experiences of climate change could affect the motivation to act on climate change, we introduce a conceptual framework that organizes insights from psychology along three clusters of processes: 1) noticing and remembering, 2) mental representations, and 3) risk processing and decision-making. Within each of these steps, we identify and explicate psychological processes that could occur when people personally experience climate change, and we formulate theory-based, testable hypotheses. By making assumptions explicit and tying them to findings from basic and applied research from psychology, this paper provides a solid basis for future research and for advancing theory.
About time: Syntactically-guided reasoning with analog and digital clocks

ABSTRACT Around the globe, young students are expected to learn about time, yet how is it that they themselves make sense of this topic? From a sociocultural perspective, sense-making about time emerges in relation to properties of available tools and representations, such as analog clocks or digital notation. Such interactions with the symbols and structural properties of clocks are examples of syntactically-guided reasoning, a key domain of early algebra. In this paper, I focus on how students’ syntactically-guided reasoning emerged when reasoning about non-routine time problems with different clocks, whether or not such reasoning was consistent with accepted conventions of time measure. I present three case studies of typical Grade 2 students describing time on a particular clock (analog or digital) as they solved tasks related to time identification and elapsed time. I describe how symbolic properties of clocks enabled pathways of thinking about time-related ideas in relation to that particular clock. Implications for the treatment of time in elementary mathematics are discussed.
A facility for the research, development, and translation of advanced technologies for ion-beam therapies

This article describes the updated GSI radiotherapy research facility (Cave M) located at the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany. This facility was upgraded by modernizing the beamline that supported a pilot project in carbon ion cancer therapy in Europe from 1997 to 2008. Descriptions are provided of the modernized beamline, related hardware components and treatment delivery system. The performance specifications and general characteristics for each major component are described, along with example pre-clinical test results of selected components. These upgrades to Cave M allow for investigating novel therapy methods. The radiotherapy research facility is located on a beamline of the heavy ion synchrotron (Schwer-Ionen-Synchrotron, or SIS-18) accelerator complex, capable of delivering 0.1 to 2 GeV/u charged particle beams, ranging from protons to uranium. This beamline contains components for fast beam gating, aborting, focusing, scanning, monitoring, and shifting the range of the beam. The beam scanning magnets, position detectors, and beam monitors are described, along with tests of functionality and performance. A dose delivery system (DDS) was adapted from a clinical unit at the National Centre for Oncological Hadrontherapy (CNAO), Pavia, Italy, and consists of modular real-time hardware and software. The DDS was modified to enable research on adaptively-managed patient motion through the use of libraries of 4D-optimized radiation treatment plans, an unsolved problem of importance for treating moving tumors. The system is modular and is designed to support future research studies, such as high dose rate (Flash) radiotherapy and radioactive ion beams. A series of validation tests confirmed the functionality and performance of various key components and systems. For example, an end-to-end test revealed that dosimetric spatial homogeneity of over 95% was achieved for square treatment fields. More generally, all performance characteristics that were tested satisfied anticipated clinical requirements.
Thymol mitigates monosodium glutamate-induced neurotoxic cerebral and hippocampal injury in rats via overexpression of nuclear erythroid 2-related factor 2 signaling pathway as well as altering nuclear factor- kappa β and glial fibrillary acidic protein expression

Monosodium glutamate (MSG) is commonly used in various food industries as a flavor enhancer. MSG is reported to cause many toxic effects, including increased neurotoxicity. The study investigates the molecular mechanisms underlying thymol's neuroprotective effect against MSG-induced neurotoxic cerebral and hippocampal injury in rats. Brain injury was induced by MSG (2 g/kg; i.p.) for 15 days. Thymol (400 & 800 mg/kg/day; p.o.) was administered along with MSG. MSG control rats showed a significant reduction in behavioral activity, elevated brain tissue oxidative stress, inflammatory parameters, Nrf2 gene up-regulation, overexpression of nuclear factor-kappa β (NF-kβ), glial fibrillary acidic protein (GFAP) as well as neuronal damage in the cerebral cortex & hippocampus. Thymol ameliorated MSG-induced brain injury via overexpression of the Nrf2 gene, thus increasing the cellular defense and organizing antioxidant & anti-inflammatory effects. Thymol improved behavioral activity and brain tissue GSH content. Thymol also decreased brain contents of MDA, NO, TNF-α & IL-6. Moreover, Thymol improved NF-kβ & GFAP immunohistochemical expression and histopathological picture in the cerebral cortex & hippocampus compared to MSG control rats. The aforementioned results suggest that thymol exhibits promising neuroprotective effects. The study elucidates the molecular mechanisms linking Nrf2 pathway signaling to oxidative stress, inflammation & NF-kβ expression underlying thymol’s protection against MSG-induced neurotoxicity. The study also highlights the role of GFAP expression in MSG-induced astrocyte injury of cerebrum & hippocampus of rats and the promising protective effects of thymol in ameliorating astrocyte injury.
Assessment of Bacteria and Parasite Contamination of Dried Sliced Beef (Kilishi) Sold within Birnin Kebbi Metropolis, Kebbi State, Northern Nigeria

Kilishi is a version of jerky that originated in Hausa land Nigeria. It is made from deboned cow, sheep or goat meat. The dried sliced beef (kilishi) is often left open in a basin thereby exposing it to flies, dust and other effects of the environment by so doing the product can be contaminated. This study was carried out to investigate the bacteria and parasite contaminants of dried slice beef (kilishi) sold in different locations within Birnin Kebbi metropolis. The samples were analyzed using pour plate method. The bacterial species were characterized and identified on the basis of their colonial morphology; gram’s staining reaction and biochemical characteristics. The protozoans and helminthes cyst/eggs morphology were identified using microscopy techniques. The total bacteria Original Research Article Jabaka et al.; SAJRM, 8(3): 58-66, 2020; Article no.SAJRM. 65518 59 plate count for each sample ranges from the highest (8x10) to the lowest (3.5x10) CFU/g from Birnin Kebbi Kalgo, Jega and Aliero samples respectively. The organisms isolated include; Staphylococcus aureus (35.2%), Escherichia coli showed 30(21.1%) percentage of occurrence, Bacillus species occurred 17(12%) Klebsiella spp 16(11.3%), Pseudomonas spp 13(9.2%), Shigella spp 10(7.04%) and the least was P. vulgaris 6(4.2%). The kilishi meat product was also contaminated with some Protozoans and helminthes contaminants which include; Acaris lumbricoides (14.2%), Entamoeba histolytica (35%), Girdia lambila (42.8%), and Taenia spp. (7.1%). It was concluded that the high bacteria count and frequency of isolates from the kilishi samples tested is an indication of high contamination of the meat by potential pathogens due to poor handling and sanitary conditions which may pose a potential source of food borne diseases.
Possibility of Environment-Friendly Hydrometallurgical Treatment of Copper-Zinc Concentrate Containing Arsenic

Pyrometallurgical treatment of copper concentrates containing arsenic poses a problem due to the emission of toxic gaseous arsenic oxides. Therefore, the development of effective environment-friendly hydrometallurgical approaches allowing extracting metals from these concentrates without gas emission is a relevant issue. The goal of the present work was to study the effect of chloride on the bioleaching of Cu-Zn concentrate containing tennantite and solid residue of its alkaline sulfide leaching (ASL) in order to evaluate the possibility to improve bioleaching of Cu-Zn concentrates containing tennantite using ASL pretreatment and NaCl addition. In NaCl absence, bioleaching of the concentrate made it possible to extract 52 and 62% of Cu and Zn for 30 days. The addition of 100 mM NaCl allowed extracting 66 and 93% of Cu and Zn. In the same time, bioleaching of ASL residue made it possible to extract 74 and 66% of Cu and Zn, while NaCl addition to the medium inhibited Cu and Zn extraction during ASL bioleaching and 35 and 62% of Cu and Zn were leached. Thus, it was shown, that both ASL pretreatment and NaCl addition increased the rate of copper and zinc bioleaching from the concentrate, while NaCl addition to the medium led to inhibition of ASL residue bioleaching. Therefore, both methods can be considered as promising approaches to increase metal extraction from Cu-Zn concentrates containing tennantite but the effect of each factor should be studied in detail to develop effective technologies.

An Experimental Study on The Correlation of Natural Rainfall Intensities and Raindrop Size Distribution Characteristics

This paper aims to study the natural raindrop size distribution characteristics based on the experimental works for three (3) different rainfall intensities, which are 32.41 mm/h, 56.84 mm/h and 85.73 mm/h. A tipping bucket rain gauge was used to record rainfall data during the field study and a professional DSLR camera (Sony α6000) was used to the capture raindrop distribution during rainfall events. A sufficient number of photographs were taken with necessary adjustments on camera setting to produce the required sharpness of the images and to significantly reduce noise disturbances. Sharp images were selected for image segmentation using a customized coding script to further process the images on MATLAB. The segmented or processed images presented in the form of numerical data would provide the details on the number of drop counts in addition to the diameters of the individual drops captured. The raindrop sizes or diameters ranging from 0.5 mm to 4.5 mm were divided into group of 0.5 mm intervals. It is found that lower rainfall intensity at 32.41 mm/h has the highest volumetric drop distribution of 1.0–1.5 mm interval drop group 78.64%. The relatively higher rainfall intensity at 85.73 mm/h tends to produce higher counts in larger droplet sizes with increments of 6.90% for 2.5–3.0 mm and increment of for 3.45% 4.0–4.5 mm. The study also recorded a significant increment of median droplet sizes (D50) ranging from 1.18 mm to 1.33 mm as the rainfall intensity increased from 32.41 mm/h to 85.73 mm/h, respectively.
Rural and urban students’ attitudes toward physics: a comparative study using Rasch analysis

Physics education researchers have put out a large number of papers about attitudes. Yet, only few papers employed Rasch model to analyze data of attitudes. This paper reports a comparative study of students’ attitudes toward physics from rural and urban high schools (n=130). In order to collect data of attitudes toward physics, the Colorado Learning Attitudes about Science Survey (CLASS) was administered online to participated students. Obtained data were analyzed by using Rasch model and t-test. Prior Rasch analysis revealed that all items of the CLASS were fitted the Rasch model and had good psychometric properties. The present research found that there were no significant differences between rural and urban students in terms of attitudes toward physics. This result was in line with some earlier finding, but contrary to other previous result. One of variables probably affecting this outcome was teachers’ unawareness of technology usage and other school facilities to enhance teaching quality.
