Authors: Moilanen Sanna , Autio Laura , Tolvanen Asko , Sevón Eija , Rönkä Anna 
Published: January 2021

AbstractThis mobile diary study examined day-today variability during one study week among university students and study-related associated factors promoting and impairing their well-being. Specifically, we explored (1) what factors university students consider as promoting and as impairing their daily wellbeing, (2) what types of daily study profiles for students can be identified based on study hours, study motivation, and academic stress, and (3) how the factors promoting and impairing students’ daily wellbeing are related to these daily study profiles. The study utilized one-week mobile diary data collected from 86 university students studying in a Finnish university (a total of 602 measurements). Seven factors promoting and eight factors impairing the wellbeing of students were identified. These included leisure time and domestic duties, social relations, sleep, rest, nutrition, and time management. Using multilevel latent profile analysis, we further identified four distinct daily study profiles: intense, productive, inefficient, and leisurely study days. The results also showed that the various factors promoting and impairing daily wellbeing were differently associated with the four study profiles.
Acquisition Centrality, Locus of Control and the Influence of Religion in Everyday Life: The Case of Urban Consumer Class of Bangladesh
Authors: Masoom Muhammad Rehan 
Published: January 2021

Abstract
The present study addresses the consequences of materialistic value-orientation (i.e. Acquisition Centrality) on the effect of the sense of control on religious experiences of the urban consumer class of Bangladesh. The central thesis is that economic transformation may contribute to the materialistic value-orientation and exert a control on the social experience; nonetheless, it would not exert any effect between the relationship of the Locus of Control and the role of religion. To test the thesis, the research investigates; given the economic growth begets acquisition centrality on a larger scale and these values, in return, often form the new purpose of social lives and emerge as a potential social force of modernity. Can religion as a century-old social institution continue to have strong-hold on the definition of social reality? To answer the question, this Cross-sectional research administered a survey of 1246 respondents from ten randomly selected distinct areas of Dhaka city and analyzed the data within a structural equation modeling (SEM) framework. The findings suggest that the people with high (External) sense of control are more likely to be influenced by their religious experiences and the people with low (Internal) sense of control have high Acquisition Centrality; Acquisition Centrality strengthened the influence of External Locus of Control on the influence of religion.

Abstract
Evidence from literature shows that deviant behavior is on high side among undergraduates in Nigeria whereas some certain psychosocial factors causing this phenomenon have not been fully explored. This study examined whether age, gender, socio-economic status and attitude towards drug abuse determine deviant behavior among the undergraduate students. It adopted ex-post facto design. Simple random sampling technique was used to sample 269 participants. The Prescription Drug Attitudes Questionnaire (PDAQ) and Deviant Behavior Variety Scale (DBVS) were used to gather data from the participants. T-test analysis and multiple regression were used to test the formulated hypotheses. The results revealed that age, monthly allowance and attitude towards drug abuse have significant joint prediction of deviant behavior (R=.358 R2 =.128, F=10.594, p<.05) while only attitude towards drug abuse independently predicted deviant behavior (R=.236, R2 =.056 F = 17.112; p<.01). Also, there was a significant gender difference on deviant behavior [t (293) = 4.196, p<.01], where male respondents scored high significantly (M=4.09, SD=3.44) compared to female respondents (M=2.53, SD=2.31) on deviant behavior. It is therefore recommended that policy makers in educational sector and the governing council of tertiary institutions need to create awareness on the debilitating effects of drugs on students’ behavior, especially among males.

Obsidian and Obsidian-like Glass Tesserae: A Multidisciplinary Approach to Study the Dedication Wall Mosaic in the Church of St. Mary of the Admiral in Palermo (12th Century)
Authors: Cantone Valentina , Deiana Rita , Silvestri Alberta , Angelini Ivana 
Published: January 2021

AbstractPliny the Elder testifies that roman workshops used volcanic glass (obsidian), but also produced and used a dark glass (obsidian-like glass) quite similar to the natural one. In the context of the study on medieval mosaics, the use of the obsidian and obsidian-like tesserae is a challenging research topic. In this paper, we present the results of a multidisciplinary study carried out on the Dedication wall mosaic, realized by a byzantine workshop in the 12th century in the Church of St. Mary of the Admiral in Palermo, and where numerous black-appearing tesserae, supposed to be composed of obsidian by naked-eyes observation, are present. Historical documents, multispectral imaging of the wall mosaic, and some analytical methods (SEM-EDS and XRPD) applied to a sample of black tesserae, concur in identifying here the presence of obsidian and different obsidian-like glass tesserae. This evidence, although related to the apparent tampering and restoration, could open a new scenario in the use of obsidian and obsidian-like glass tesserae during the Byzantine period in Sicily and in the reconstruction of multiple restoration phases carried out between 12th and 20th century AD on the mosaics of St. Mary of the Admiral.

Published: January 2021

AbstractThis research project concerns the study, analysis and dating of obsidian flows on the island of Lipari, in relation to the population of the Aeolian Islands, during the Neolithic period.The collection, processing and diffusion of Lipari obsidian characterise the Neolithic population of Lipari and the entire Mediterranean. By improving the knowledge of supply methods in the territory, it will be possible to formulate hypotheses on the chronology of the sources, the ways of collecting the raw material and on the mobility of the Neolithic communities in the Aeolian Islands. The scientific research is divided into two main topics: the first concerns the analytical and methodological aspects of archaeological and geological studies of Lipari obsidian; the second, the formation of obsidian at Lipari, their sources and lithological characteristics. Throughout the duration of this study we will perform new age determinations of Neolithic obsidian artefacts and geological samples, directly with the method of fission track, and indirectly dating paleo soils using the radiocarbon method.
“By Degrees”
Authors: Giles Paul 
Published: January 2021

Paul Giles, “‘By Degrees’: Jane Austen’s Chronometric Style of World Literature” (pp. 265–293)
This essay considers how Jane Austen’s work relates to “World Literature” by internalizing a chronometric style. Examining the emergence of the chronometer in the eighteenth century, it suggests how Austen drew on nautical frames of reference to combine disparate trajectories of local realism, geographical distance, and historical time. The essay thus argues that Austen’s fiction is interwoven with a reflexive mode of cartographic mapping, one that draws aesthetically on nautical instruments to remap time and space. This style involves charting various fluctuations of perspective that reorder history, memory, and genealogy, while also recalibrating Britain’s position in relation to the wider world. Moving on from an initial analysis of Austen’s juvenilia and early novels, the essay proceeds in its second part to discuss Mansfield Park (1814) in relation to Pacific exploration and trade. In its third part, it considers Emma (1815) in the context of comic distortions and the misreadings that arise from temporal and spatial compressions in the narrative, a form heightened by the novel’s reflexive wordplay. Hence the essay argues that Austen’s particular style of World Literature integrates chronometric cartography with domestic circumstances, an elusive idiom that also manifests itself in relation to the gender dynamics of Persuasion (1817) and the unfinished “Sanditon,” as discussed in the essay’s concluding pages. This is correlated finally with the way Austen’s novels are calibrated, either directly or indirectly, in relation to a global orbit.

Published: January 2021

[Introducción]: El Análisis de Ciclo de Vida (ACV) es una metodología robusta y reconocida para determinar la magnitud de los impactos ambientales de un producto. [Objetivo]: El objetivo de la investigación fue evaluar el impacto sobre el cambio climático de las tarimas de madera. [Metodología]: Los límites del sistema van desde la preparación del terreno para establecer las plantaciones, hasta la puerta de llegada a la empacadora de fruta. Se evaluaron dos unidades funcionales: a) una tarima con dimensiones comerciales para la manipulación y trasiego de productos agrícolas y b) un metro cúbico de madera para producción de tarimas. La temporalidad de los datos comprendió al periodo 2014-2017 y la de los resultados del Análisis de Ciclo de Vida un ciclo de rotación de 12 años para plantaciones de melina (Gmelina arborea Roxb). Se evaluaron dos sistemas de producto: con biomasa en el tratamiento térmico y con gas LP. [Resultados]: El primero presentó un impacto potencial levemente menor. En ambos casos, la combustión de diésel asociada al transporte de madera rolliza fue la etapa más intensa en emisiones, libera cerca de 1.61 kg CO2-eq tarima-1 y 43.22 kg CO2-eq m-3. El diésel, en todas las etapas del ciclo de vida, es la principal fuente de emisión de gases de efecto invernadero, ya que libera 2.31 kg CO2-eq tarima-1 y 86.57 kg CO2-eq m-3. [Conclusiones]: Las oportunidades de mejora en el desempeño ambiental del producto se encuentran en el uso de vehículos de carga más eficientes y en la reducción de la distancia entre las plantaciones forestales y la planta de aserrío.

Fault-Plane Determination of the 4 January 2020 Offshore Pearl River Delta Earthquake and Its Implication for Seismic Hazard Assessment
Authors: Chen Han , He Xiaohui , Yang Hongfeng , Zhang Jiangyang 
Published: January 2021

AbstractOn 4 January 2020, an ML 3.5 earthquake occurred in the Pearl River Estuary (PRE) and was felt at a distance of more than 200 km. According to the China Earthquake Networks Center, this event has been the only M&gt;3 earthquake within the PRE since 1900. The Guangdong–Hong Kong–Macau Bay Area (GHMBA) surrounding the PRE is one of China’s most critical financial circles, and coastal earthquake hazard has become an increasing concern. Investigating the source parameter and causative fault of this earthquake is helpful for seismic hazard estimation and mitigation in the GHMBA. In this study, we first determined the focal mechanism of the mainshock using the cut-and-paste method. We then used the sliding-window cross-correlation method to detect foreshocks and aftershocks before relocating the earthquakes. Finally, we conducted forward modeling to retrieve the rupture directivity of the mainshock, using waveforms of one aftershock as empirical Green’s functions. The results demonstrate that this earthquake was an Mw 3.7 strike-slip event, with a focal depth of 10 km. The rupture direction of the mainshock was 78°, consistent with the northeast-east-trending fault system in the region. The identified source fault confirmed a seismogenic segment of the northeast-east-trending fault system in the PRE, which is the primary source of seismic hazard in the area.

One of the main consequences of climate change in Brazil is the increase in the occurrence of extreme rainfall, which in turn trigger Hydrometeorological disasters; the Brazilian continental dimension, the regional characteristics of biomes and socioeconomic inequality are conditioning factors for the impacts of extreme events in the country. This work analyzes Brazil’s socioeconomic and urban infrastructure vulnerability, combined with the regional exposure of the population, based on disasters observed and future scenarios for the occurrence of rainfall extremes. As a result, it points out that climate change impact differently on large Brazilian regions, due to population density and the poor quality of urban infrastructure services.

Decision trees are data mining techniques for extracting hidden knowledge from large databases. This study was performed to establish the risk factors associated with halitosis by applying a decision tree model in a Turkish population and examining the interactions between these factors. We obtained data from a total of 1.290 patients, consisting of 645 patients with halitosis and 645 healthy controls. The subjects’ demographic characteristics, smoking status, alcohol intake, medical history and medications were assessed. The presence of potential intraoral causes of halitosis was determined by investigating perceived oral health problems such as caries, periodontal diseases, tongue coating, and oral cavity pathologies. Halitosis level was evaluated using an organoleptic scale. All data were subjected to classification tree analyses. Halitosis was significantly more common in patients with (80.9%) than without (20.7%) oral health problems (P &lt; 0.001). Halitosis was significantly less common in non-smokers without oral health problems than in smokers with oral health problems (14.5%; P &lt; .001). Halitosis was evident in all patients with oral health problems, smokers, and those with respiratory diseases (100%). The effects of systemic diseases on halitosis were significant in non-smokers without oral health problems (P &lt; 0.05). Respiratory conditions showed significant effects on halitosis in smokers with oral health problems (P &lt; 0.01). We developed a decision tree model to identify risk factors associated with halitosis. The classification tree method showed that the most significant factors affecting halitosis were oral health problems followed by smoking status.

To examine the effects of stress, bruxism, malocclusion, and oral habits on the incidence of temporomandibular disorders (TMDs) using a classification tree method (CTM). We obtained data from a total of 1.338 patients: 669 who had TMDs and 669 who but haven’t TMDs. We recorded interview data on stress and oral habits, and during oral examination, noted malocclusions, bruxism, and any sign of poor oral habits. All data were subjected to CTM analyses. The TMD rate was highest in stressed patients (96.8%), and significantly lower in stress-free patients (25.3%) (P &lt; 0.001). TMD was evident in all patients exhibiting both stress and bruxism (100.0%). In stressed patients lacking bruxism, the effects of malocclusion on TMD were significant (P &lt; 0.001). CTM analyses showed that the most significant factor affecting TMD was stress, followed by bruxism and malocclusion. This is the first report to use CTM to define factors affecting TMD.

Executive Perspective
Running a big company is not as complicated as you might think. There are only a few things you have to do, but high on the list is the ability to identify significant business risks and to decide how they will be mitigated. No doubt scientists will continue to argue for years to come about the scale and intensity of climate change and about the part in this process that human activity is playing. But one thing is certain, climate change presents a significant and immediate risk, not just to business but to the way we conduct our lives, and to the kind of world that we will leave to our children and our grandchildren.

Retaining Women in the Oil and Gas Industry
Authors: Sprunt Eve S. 
Published: January 2021

Feature
One can draw several conclusions from the results of this informal survey: Work/life balance is a huge issue for everyone. Flexible working arrangements including part-time work and telecommuting will help retain people of all ages. While childcare benefits are of interest to only a fraction of the workforce, for that fraction, they can be the deciding factor. The same types of flexible work policies and on-site daycare or childcare support that will help to retain young women will also help to retain young men. Often women are the primary breadwinners and/or healthcare benefit providers for their families and do not have the luxury of working less than full time. The key is flexibility to create a win-win situation for worker and employer.
