Abstract. Long-term measurements of atmospheric mass concentrations
of black carbon (BC) are needed to investigate changes in its emission,
transport, and deposition. However, depending on instrumentation, parameters
related to BC such as aerosol absorption coefficient (babs) have been
measured instead. Most ground-based measurements of babs in the Arctic
have been made by filter-based absorption photometers, including particle
soot absorption photometers (PSAPs), continuous light absorption photometers
(CLAPs), Aethalometers, and multi-angle absorption photometers (MAAPs). The
measured babs can be converted to mass concentrations of BC (MBC) by
assuming the value of the mass absorption cross section (MAC; MBC= babs/ MAC). However, the accuracy of conversion of babs to MBC
has not been adequately assessed. Here, we introduce a systematic method for
deriving MAC values from babs measured by these instruments and
independently measured MBC. In this method, MBC was measured with a
filter-based absorption photometer with a heated inlet (COSMOS).
COSMOS-derived MBC (MBC (COSMOS)) is traceable to a rigorously
calibrated single particle soot photometer (SP2), and the absolute accuracy
of MBC (COSMOS) has been demonstrated previously to be about 15 % in
Asia and the Arctic. The necessary conditions for application of this method
are a high correlation of the measured babs with independently measured
MBC and long-term stability of the regression slope, which is denoted
as MACcor (MAC derived from the correlation). In general,
babs–MBC (COSMOS) correlations were high (r2= 0.76–0.95 for
hourly data) at Alert in Canada, Ny-Ålesund in Svalbard, Barrow (NOAA Barrow Observatory) in
Alaska, Pallastunturi in Finland, and Fukue in Japan and stable for up to
10 years. We successfully estimated MACcor values (10.8–15.1 m2 g−1 at a wavelength of 550 nm for hourly data) for these instruments,
and these MACcor values can be used to obtain error-constrained
estimates of MBC from babs measured at these sites even in the past,
when COSMOS measurements were not made. Because the absolute values of
MBC at these Arctic sites estimated by this method are consistent with
each other, they are applicable to the study of spatial and temporal
variation in MBC in the Arctic and to evaluation of the performance of
numerical model calculations.
Evaluation of convective cloud microphysics in numerical weather prediction model with dual-wavelength polarimetric radar observations: methods and examples
Authors: Köcher Gregor , Zinner Tobias , Knote Christoph , Tetoni Eleni , Ewald Florian , Hagen Martin
Published: October 2021

Abstract. The representation of cloud microphysical processes contributes substantially to the uncertainty of numerical weather simulations. In part, this is owed to some fundamental knowledge gaps in the underlying processes due to the difficulty to observe them directly. On the path to close these gaps we present a setup for the systematic characterization of differences between numerical weather model and radar observations for convective weather situations. Radar observations are introduced which provide targeted dual-wavelength and polarimetric measurements of convective clouds with the potential to provide more detailed information about hydrometeor shapes and sizes. A convection permitting regional weather model setup is established using 5 different microphysics schemes (double-moment, spectral bin (FSBM), and particle property prediction (P3)). Observations are compared to hindcasts which are created with a polarimetric radar forward simulator for all measurement days. A cell-tracking algorithm applied to radar and model data facilitates comparison on a cell object basis. Statistical comparisons of radar observations and numerical weather model runs are presented on a dataset of 30 convection days. In general, simulations show too few weak and small-scale convective cells. Contoured frequency by altitude distributions of radar signatures reveal deviations between the schemes and observations in ice and liquid phase. Apart from the P3 scheme, simulated reflectivities in the ice phase are too high. Dual-wavelength signatures demonstrate issues of most schemes to correctly represent ice particle size distributions, producing overly large graupel particles. Comparison of polarimetric radar signatures reveal issues of all schemes except the FSBM to correctly represent rain particle size distributions.
Was there a glacial outburst flood in the Torngat Mountains during Marine Isotope Stage 3?
Authors: Pico Tamara , Willenbring Jane , Dalton April S. , Hemming Sidney
Published: October 2021

Abstract. We report previously unpublished evidence for a Marine Isotope Stage 3 (MIS 3; 60–26 ka) glacial outburst flood in the Torngat Mountains (northern Quebec/Labrador, Canada). We present 10Be cosmogenic exposure ages from legacy fieldwork for a glacial lake shoreline with evidence for outburst flooding in the Torngat Mountains, with a minimum age of 36 ± 3 ka (we consider the most likely age, corrected for burial, to be ~56 ± 3 ka). This shoreline position and age can potentially constrain the Laurentide Ice Sheet margin in the Torngat Mountains. This region, considered a site of glacial inception, has no published dated geologic constraints for high-elevation MIS 3 ice margins. We estimate the freshwater flux associated with the inferred glacial outburst flood using high-resolution digital elevation maps corrected for glacial isostatic adjustment. Using assumptions about the ice-dammed locations we find that a freshwater flood volume of 1.14 × 1012 m3 could have entered the Hudson Strait. This glacial outburst flood volume could have contributed to surface ocean freshening to cause a measurable meltwater signal in δ18O records, but would not necessarily have been associated with substantial ice rafted debris. Future work is required to refine estimates of the size and timing of such a glacial outburst flood. Nevertheless, we outline testable hypotheses about the Laurentide Ice Sheet and glacial outburst floods, including possible implications for Heinrich events and glacial inception in North America, that can be assessed with additional fieldwork and cosmogenic measurements.
Signal response of the Swiss plate geophone monitoring system impacted by bedload particles with different transport modes
Authors: Chen Zheng , He Siming , Nicollier Tobias , Ammann Lorenz , Badoux Alexandre , Rickenmann Dieter
Published: October 2021

Abstract. Controlled experiments were performed to investigate the acoustic signal response of the Swiss plate geophone (SPG) system impacted by bedload particles varying in size, impact angle and transport mode. The impacts of bedload particles moving by saltation, rolling, and sliding were determined by analyzing the experimental videos and corresponding vibration signals. For a particle impact on the bed or on the geophone plates, the signature of the generated signal in terms of maximum amplitude, number of impulses and centroid frequency was extracted from the raw monitoring data. So-called signal packets were determined by performing a Hilbert transform of the raw signal. The number of packets was calculated for each transport mode and for each particle size class, with sizes ranging from 28.1 mm to 171.5 mm. The results show how the number of signal impulses per particle mass, the amplitude of the signal envelope, and the centroid frequency change with increasing particle size, and they also demonstrate the effect of bedload transport mode on the signal response of the SPG system. We found that there is a general increase in the strength of the signal response or in the centroid frequency when the transport mode changes from sliding to rolling to saltation. The findings of this study help to better understand the signal response of the SPG system for different bedload transport modes, and may also contribute to an improvement of the procedure to determine bedload particle size from the SPG signal.
Magnitude and source area estimations of severe prehistoric earthquakes in the western Eastern Alps
Authors: Oswald Patrick , Strasser Michael , Skapski Jens , Moernaut Jasper
Published: October 2021

Abstract. In slowly deforming intraplate tectonic regions such as the Alps only limited knowledge exists on the occurrence of severe earthquakes, their maximum possible magnitude and their potential source areas. This is mainly due to long earthquake recurrence rates exceeding the time span of instrumental earthquake records and historical documentation. Lacustrine paleoseismology aims at retrieving long-term continuous records of seismic shaking. A paleoseismic record from a single lake provides information on events for which seismic shaking exceeded the intensity threshold at the lake site. In addition, when positive and negative evidence for seismic shaking from multiple sites can be gathered for a certain time period, minimum magnitudes and source locations can be estimated for paleo-earthquakes by a reverse application of an empirical intensity prediction equation in a geospatial analysis. Here, we present potential magnitudes and source locations of four paleo-earthquakes in the western Eastern Alps based on the integration of available and updated lake paleoseismic data. The paleoseismic records at Plansee and Achensee covering the last ~10 kyrs were extended towards the age of lake initiation after deglaciation to obtain the longest possible paleoseismic catalogue at each lake site. Our results show that 25 severe earthquakes are recorded in the four lakes Plansee, Piburgersee, Achensee and potentially Starnbergersee over the last ~16 kyrs, from which four earthquakes are interpreted to left imprints in two or more lakes. Earthquake recurrence intervals range from ca. 1,000 to 2,000 years with a weakly periodic to aperiodic recurrence behavior for the individual records. We interpret that relatively shorter recurrence intervals in the more orogen-internal archives Piburgersee and Achensee are related to enhanced tectonic loading, whereas a longer recurrence rate in the more orogen-external archive Plansee might reflect a decreased stress transfer across the current-day enhanced seismicity zone. Plausible epicenters of paleo-earthquake scenarios coincide with the current enhanced seismicity regions. Prehistoric earthquakes with a minimum moment magnitude (MW) 5.8–6.1 might have occurred around the Inn valley, the Brenner region and the Fernpass-Loisach region, and might have reached up to MW 6.3 at Achensee. The paleo-earthquake catalogue might hint at a shift of severe earthquake activity near the Inn valley from east to west to east during Postglacial times. Shakemaps highlight that such severe earthquake scenarios not solely impact the enhanced seismicity region of Tyrol, but widely affect adjacent regions like southern Bavaria in Germany.
Flood–pedestrian simulator for modelling human response dynamics during flood-induced evacuation: Hillsborough stadium case study
Authors: Shirvani Mohammad , Kesserwani Georges
Published: October 2021

Abstract. The flood–pedestrian simulator uses a parallel approach to couple a hydrodynamic model to a pedestrian model in a single agent-based modelling (ABM) framework on graphics processing units (GPU), allowing dynamic exchange and processing of multiple-agent information across the two models. The simulator is enhanced with more realistic human body characteristics and in-model behavioural rules. The new features are implemented in the pedestrian model to factor in age- and gender-related walking speeds for the pedestrians in dry zones around the floodwater and to include a maximum excitement condition. It is also adapted to use age-related moving speeds for pedestrians inside the floodwater, with either a walking condition or a running condition. The walking and running conditions are applicable without and with an existing two-way interaction condition that considers the effects of pedestrian congestion on the floodwater spreading. A new autonomous change of direction condition is proposed to make pedestrian agents autonomous in wayfinding decisions driven by their individual perceptions of the flood risk or the dominant choice made by the others. The relevance of the newly added characteristics and rules is demonstrated by applying the augmented simulator to reproduce a synthetic test case of a flood evacuation in a shopping centre, to then contrast its outcomes against the version of the simulator that does not consider age and gender in the agent characteristics. The enhanced simulator is demonstrated for a real-world case study of a mass evacuation from the Hillsborough football stadium, showing usefulness for flood emergency evacuation planning in outdoor spaces where destination choice and individual risk perception have great influence on the simulation outcomes.
Smoother versus sharper Gulf Stream and Kuroshio sea surface temperature fronts: effects on cyclones and climatology
Authors: Tsopouridis Leonidas , Spengler Thomas , Spensberger Clemens
Published: October 2021

Abstract. The Gulf Stream and Kuroshio regions feature strong sea surface temperature (SST) gradients that influence cyclone development and the storm track. Previous studies showed that smoothing the SSTs in either the North Atlantic or North Pacific yields a reduction in cyclone activity, surface heat fluxes, and precipitation, as well as a southward shift of the storm track and the upper-level jet. To what extent these changes are attributable to changes in individual cyclone behaviour, however, remains unclear. Comparing simulations with realistic and smoothed SSTs in the atmospheric general circulation model AFES, we find that the intensification of individual cyclones in the Gulf Stream or Kuroshio region is only marginally affected by reducing the SST gradient. In contrast, we observe considerable changes in the climatological mean state as well as a reduced cyclone activity in the North Atlantic and North Pacific storm tracks that are shifted equatorward in both basins. The upper-level jet in the Atlantic also shifts equatorward, while the jet in the Pacific strengthens in its climatological position and extends further east. Surface heat fluxes, specific humidity, and precipitation also respond strongly to the smoothing of the SST, with a considerable decrease in their mean values on the warm side of the SST front. This decrease is more pronounced in the Gulf Stream than in the Kuroshio region, due to the larger decrease in SST along the Gulf Stream SST front. Considering the differences of the different variables occurring within/outside of a 750 km radius of any cyclone over their entire lifetime, we find that cyclones play only a secondary role in explaining the differences in the mean state between the smoothed and realistic SST experiments.

Actualmente, la economía global se ha visto afectada gravemente por la pandemia causada por el COVID-19, inclusive llegando a causar un cierre parcial de actividades generalizadas consideradas como no prioritarias, sin embargo, uno de los sectores esenciales que mostró crecimiento en algunos países fue el agroalimentario, por lo que es importante que este tipo de empresas mejoren sus decisiones de tal manera que les permite lograr un mejor desempeño en mercados tan turbulentos. El objetivo del estudio es analizar el impacto que tiene la orientación emprendedora (OE), considerada como un enfoque estratégico, en el desempeño de este tipo de empresas. Se llevó a cabo una encuesta a una muestra de 170 pequeñas y medianas empresas de agronegocios del Estado de Aguascalientes, mediante un modelo de ecuaciones estructurales se obtuvieron resultados, que al ser analizados muestran un impacto positivo y significativo entre la orientación emprendedora y el desempeño. La orientación emprendedora es un enfoque estratégico positivo en tiempos de turbulencia, aunado a la importancia del sector agroalimentario en la economía mundial. Se concluye que las empresas de agronegocios deberán desarrollar capacidades internas relacionadas con la proactividad de sus integrantes, la búsqueda de innovaciones y con la toma de riesgos, todo en búsqueda de incrementar su desempeño.
Matar al dragón; matar al diablo. La naturaleza como escenario de acción de san Miguel y san Jorge en algunos ejemplos pictóricos bajomedievales y renacentistas (siglo XV e inicios del XVI)
Authors: Consiglieri Nadia Mariana
Published: October 2021

La naturaleza resultó un tópico frecuente en las representaciones pictóricas bajomedievales y renacentistas de san Miguel y san Jorge matando al dragón o a Satán. Estos santos se instalaron con fuerza en la cultura visual del Occidente medieval a partir del siglo XII. Su objetivo de mostrar el triunfo del cristianismo sobre el enemigo religioso se sustentó en la construcción de un aparato de imágenes cada vez más verosímiles y efectistas. Así, la naturaleza pasó a ser el escenario de acción predilecto para situar estos combates, gracias a la introducción de determinados detalles, plantas y animales para aludir a lo salvaje y a lo indómito relacionado con las fuerzas malignas. Este trabajo propone analizar estos aspectos en algunas pinturas europeas de los siglos XV e inicios del XVI.
Del té al ginkgo: estudios e ilustraciones prelinneanas de la flora japonesa en las publicaciones europeas
Authors: Sanz Guillén Alejandro M.
Published: October 2021

ras un periodo de ricos intercambios culturales desarrollado durante el periodo Namban (1543-1639), las autoridades japonesas decidieron cerrar las fronteras del archipiélago a los occidentales, haciendo una excepción con los comerciantes de la Compañía Neerlandesa de Indias Orientales. Este aislacionismo se produjo en un momento en el cual los libros ilustrados de estudios botánicos sobre regiones de fuera de Europa tenían una gran recepción entre los lectores y médicos occidentales. En el siguiente trabajo estudiaremos las publicaciones y las estampas sobre flora nipona publicados en el Viejo Continente gracias a las investigaciones de una serie de trabajadores ligados a la compañía neerlandesa, quienes pudieron visitar el archipiélago a finales del siglo xvii. Gracias a estos botánicos, se pudieron editar en Occidente por primera vez una serie de descripciones sobre las plantas de Japón, antes de la publicación de los trabajos de Carlos Linneo, Systema naturæ (Leiden, 1735) y Species Pantarum (Estocolmo, 1753).
Antoni Gaudí y Joan Rubió. Naturaleza y paisaje en las vidrieras de la Catedral de Mallorca
Authors: De Mirabò Gralla Concepció Bauçà
Published: October 2021

La reforma encabezada por Antoni Gaudí en la Catedral de Mallorca a partir de 1903 incluyó el proyecto, largamente ansiado, de abrir sus ventanales a la luz. Dicha tarea que solamente pudo iniciar, sería continuada por su discípulo y colaborador, Joan Rubió, hasta los años treinta. Desde la genialidad de las primeras vidrieras hasta la menor calidad de las últimas, lo cierto es que muchas de ellas otorgaron un papel destacado a la naturaleza y al paisaje como medios para vehicular el mensaje religioso, así como la inspiración en el entorno cercano, concebido como fórmula de identidad y de integración. Ello se explica a partir del pensamiento de Gaudí y del trasfondo ideológico y cultural que compartió con Rubió durante su estancia en Mallorca, concretándose en la originalidad de las piezas del primero y en las influencias artísticas que acabaron impregnando, décadas después, las del segundo.
La Tierra personificada: evolución iconográfica y dimensión simbólica
Authors: Rodríguez López María Isabel
Published: October 2021

Los griegos imaginaron a la diosa Gea, la Tierra, como el origen de todo lo creado; así se refirieron a ella tanto las fuentes literarias como los artistas desde la Antigüedad. La imagen de la diosa fecunda se asoció a diferentes mitos y también sirvió como personificación del elemento natural, desmitificada o formando parte de un marco simbólico/filosófico diverso, en virtud de los soportes artísticos y de los contextos en los que fue representada. Atenderemos a la iconografía de la Tierra, desde la antigua Grecia hasta el umbral de la Edad Media.
El descubrimiento del paisaje en China: la influencia de la imaginería taoista
Authors: Romero Leo Jaime
Published: October 2021

Este artículo plantea una reflexión sobre el descubrimiento del paisaje en China usando como base las teorías de Javier Maderuelo y Augustin Berque sobre la génesis del concepto de «paisaje». Para llevar a cabo el análisis se propone a las imágenes relacionadas con los paraísos de los inmortales taoístas como el elemento fundamental que posibilitó dicho desvelamiento. De este modo, la influencia de aquellos paraísos idílicos en terrenos montañosos habitados por inmortales, llevaron a China a ser la primera civilización del mundo en contemplar y percibir, con deleite estético, el paisaje que conformaba sus entornos naturales (shanshui). En este sentido, ya en la dinastía Tang (618-907) cabría hablar de un desvelamiento del paisaje propiamente dicho y de la consolidación de una poesía y una pintura paisajista.
Para una teoría del performanymal. De la representación a la presencia animal en el arte contemporáneo
Authors: Silvestre Federico L. , Rodríguez Alonso Guillermo
Published: October 2021

Este artículo analiza un conjunto de manifestaciones artísticas contemporáneas que se caracterizan por su voluntad de aprehender la naturaleza viva, desbordando, con ello, las lógicas tradicionales de la representación en Occidente. Si bien el arte europeo parece haber tenido siempre presente la problemática relación vida/naturaleza/arte, no fue hasta el siglo XX que algunos artistas comenzaron a introducir seres vivos en sus obras. No obstante, los modos en que lo vivo puede ser representado son diversos, y sus resultados muchas veces inesperados. Para aproximarnos a esta complejidad, proponemos aquí el concepto de performanymal como herramienta que nos permite abordar una serie de iniciativas artísticas que, en sintonía con ciertas corrientes filosóficas neovitalistas y nuevos paradigmas de la biología, tratan de hacer comparecer la vida en lugar de intentar representarla mediante indicios, símbolos, o reducciones objetivas. Nuestro estudio profundiza en tres manifestaciones artísticas clave de la historia del arte europeo (el cine surrealista-científico de Jean Painlevé, las performances de Walter Marchetti y el Grupo Zaj, y el arte de situaciones en curso de Pierre Huyghe) que comparten un marcado interés por ahondar en nociones como el error, el azar, el devenir, y el juego –parámetros que reformulan la lógica de la representación en favor de una concepción de la naturaleza como realidad en movimiento que excede todo determinismo y pone en tela de juicio ciertas categorías heredadas del arte y la filosofía occidentales.

Sexual and Marital Relationship Satisfaction in Parents of Children With Disabilities
Authors: Kijak Remigiusz
Published: October 2021

The purpose of this study was to determine the level of sexual satisfaction and type of relationship between spouses, and then to determine the correlation between these variables and independent variables. These include: disability type of the child, the number of children in the family, and the gender of the parents. The hypothesis was that ‘the level of sexual satisfaction in parents is significantly related to the type of disability possessed by their children’ and similarly it was found that disability type significantly affects the type of relationship between parents. The research was conducted using the Matched Marriage Questionnaire (MMQ) and the Sexual Satisfaction Scale (SSS). The data obtained in the study showed that most spouses experience high and average sexual satisfaction and no particular differences between men and women were observed. The differences appeared when analyzing parents of a child with autism. In this group the results were more diverse in the detailed descriptions of the scale. The results obtained regarding marital relationship satisfaction indicate a not very favorable picture of the relationships of the surveyed subjects.
Expressive Suppression in Parents of Children with Disabilities
Authors: Juszko Karolina , Szczepańska-Gieracha Joanna
Published: October 2021

Raising and caring for children with disabilities involves a number of challenges that most parents/caregivers are unprepared for. Dealing with negative emotions such as guilt, lack of fulfillment, disappointed hopes, fear, shame and even despair can adversely affect the life of the entire family. Expressive suppression protects the ward and other family members from an outward expression of the caregiver’s emotions and prevents conflicts, but it does nothing to alleviate the caregiver’s internal emotional state. This study diagnoses the problem of expressive suppression in parents/caregivers of children with disabilities and assesses the connection between suppressed emotions and anxiety/depressive symptoms based on the Courtauld Emotional Control Scale (CECS) and the shortened Hamilton Depression Rating Scale (HAMD-7). The study involved 60 parents of children with disabilities living in metropolitan, urban, and rural areas. An elevated level of expressive suppression and the occurrence of anxiety-depressive disorders occurred in over half of the parents. Using non-parametric methods, a significant weak positive correlation (p = 0.398) is observed between the sum of the points obtained on the CECS scale and the sum of the points on the HAMD-7 scale. In the group with the elevated levels of expressive suppression, a significant strong positive correlation (p = 0.612) is observed between the sum of the points obtained on the CECS scale and the place of residence (with a higher degree of expressive suppression in parents from rural areas). There is also a significant correlation between the sum of points scored on the HAMD-7 scale and the financial standing of the families (p = 0.667), which reflects the impact of low social status on the occurrence of anxiety and depressive disorders.

De « Riquet à la Houppe » dans les réécritures contemporaines Un éclairage sociopoétique
Authors: CONNAN-PINTADO Christiane
Published: October 2021

To illustrate his theoretical presentation of sociopoetics, Alain Montandon uses the rewriting of traditional tales in contemporary times. Pascale Auraix-Jonchière reminds us that many tales, and long before the term was in use, present characters that can be described as ‘disabled’. We propose to focus on the main character of ‘Riquet à la houppe’, stigmatised, despite his high-ranking birth, by an accumulation of infirmities. After having enjoyed undeniable success from the 17th to the 19th century, this little-known tale is rarely published today. We wish to examine this rarity in some reformulations, including iconographic ones. To observe these variations, in which disability echoes social representations, we will study the trio of characters in the tale: not only the eponymous hunchbacked, lame and ugly hero, but also the two sisters who are also ‘disabled’, one ugly and witty, like Riquet, the other with a beauty that struggles to compensate for her mental and intellectual deficit. How are these characters represented in contemporary production? How are their handicaps socially considered when ‘the tyranny of appearances’ (Amadieu, 2002) or the influence of feminist currents incite to renew the look on this tale?
Energy Poverty, Climate Change and Economic Growth
Authors: S.J. Afaha , G.D. Ifarajimi
Published: October 2021

The study objectives were to determine the short and long-run effects of energy poverty and climate change on economic growth and to theoretically describe the driving factors of household energy poverty status using the Nigeria Demographic and Health Survey (NDHS) dataset, 2018. The Autoregressive Distributed Lagged (ARDL) model was used to estimate variables based on data from 1980 to 2018. The results indicate that energy poverty has a negative or inverse relationship with the GDP growth; energy imports contribute an average of ten percent to the value of the GDP growth. Traditional and dangerous forms of energy use are predominant in Nigerian households. This poses a threat not only to the environment but also to the health of the public. An awareness-raising campaign on using safe and environmentally friendly energy sources should be a priority in Nigeria. Likewise, energy poverty reduction interventions, probably in the form of promotion of cheap and efficient clean energy technologies in the rural sector and the northern region (most especially Northeast), should be executed to enable the households to exit the energy poverty trap. Income smoothing policy measures probably in the form of poverty reduction and safety-net programs should be directed towards the low-income earners in the country in order to ease their level of poverty, of which energy poverty is an important segment.

Published: October 2021

This study explored the effective application of Maple software to reduce student teachers’ errors in Integral Calculus at Evangelical Presbyterian College of Education, Volta Region – Ghana. The study employed the quasi-experimental non-equivalent group design. Convenience and simple random sampling techniques were employed to obtain a sample of 80 students, which consisted of 40 students in the control group and 40 in the experimental group. Teacher-made Pre, -Post-Calculus Achievement Tests (CAT), and questionnaires were used to collect quantitative and qualitative data respectively. Descriptive, Independent samples t-test and paired samples t-test were used in analyzing the data. Descriptive error analysis revealed that students committed many conceptual, procedural and technical errors when solving Integral Calculus tasks. The results also indicated that there was a statistically significant difference between students of the experimental group exposed to the use of Maple software in learning integral calculus to the control group exposed to traditional methods. The researchers recommend Maple assisted instruction in the teaching and learning of Integral Calculus and also the need to employ a blended teaching approach, in which Maple software is used simultaneously with traditional teaching strategy.
Ethical Consumerism and its effect on Purchase Decision: Evidence from Fashion Industry of Pakistan
Authors: Hussain Asad , Dar Faizan
Published: October 2021

In recent years, customer’s increasing awareness of ethical consumption has become increasingly important for the business environment and one’s lifestyle. Although it is observed that consumers are influenced by their ethical concerns but ethical consumptions lack from a consumer perspective. The theoretical framework of the paper portrays the multifaceted and complex ratio of the concepts of ethical consumption and the complexities that exist in the relationship between purchase influence and consumption in general. The study took a quantitative approach to find out how consumer purchase decision is affected by four antecedents namely, Ethical Knowledge, Environmental Concern, Personal Values, and Price Factor. Data was collected through a self-developed questionnaire and distributed among 200 respondents in Karachi, Pakistan. Multiple regression was applied through SPSS in the data. The results of the study show that all other variables show a significant effect on purchase decision except Ethical Knowledge. Therefore, it implies consumers are uncertain about which products and firms follow ethical rules and which do not. This study has theoretical and practical contributions in the fashion industry context. This research might encourage fashion brands to willfully take on green exercises and give strategic guidelines to advertisers and retailers about their sustainable retail practices.
Ongoing Information Search Motivation: An Influencer of Users’ Approval of Facebook Banner Adverts
Authors: Anwar Imran , Haider Kamal , Iqbal Shahid
Published: October 2021

Facebook is a leading social network site worldwide and Facebook users use this social medium for several interactional reasons like to socialize or access and share informative content with others. Several users participate in Facebook to fulfil their ongoing information needs. The current research investigates the ongoing information search motivation (OISM) as an influencer of users’ approval of Facebook banner advertising. To investigate the study phenomenon, primary data was collected through online survey questionnaires from 230 Facebook users in Pakistan. Structural Equation Modeling was conducted to examine the construct validity and to test the model and hypotheses. The results showed OISM as an important influencer of users’ attitude towards Facebook banner advertising. Moreover, the analysis also revealed that the Facebook banner ad informativeness mediated the relationship between users’ OISM and their attitudes toward Facebook banner advertising. Additionally, attitude towards Facebook banner advertising was also found to be influencing the users’ Facebook banner ad-click behavior. These findings can be beneficial to social media marketers and marketing managers to organize user-relevant Facebook banner ad content. The study findings can specifically be implied to social media customers in Pakistan.

Published: October 2021

This research aims to identify the factors influencing Higher Education Institutes (HEIs) to adopt Social Media (SM) for marketing communication. The research was conducted through a qualitative study by interviewing SM managers of selected Pakistani HEIs. Data was analyzed using NVivo 11 to identify emerging themes. The findings revealed several internal and external factors encouraging HEIs to adopt SM marketing. Internal factors reflected the internal dynamics or beliefs within the HEIs that encouraged them to use SM for their marketing communication, whereas external factors were environmental changes, not in direct control of HEIs, but believed to contribute towards their decision to use SM. The internal factors included the belief of applicants, increased interest of senior management towards SM, perception of cost-effective promotional tool, induction of young staff, perception of SM as a modern communication tool and move towards paperless communication. The external factors included SM preference as a mode of communication, declining value of traditional marketing communication tools, E-Life inclination, presence of competitors & unofficial SM accounts of HEIs and their self-driven nature. This study draws focus towards the underlying intentions of HEIs for their SM presence and compares these motivations with other organizations.

From a practical perspective, the findings of this study will enable HEIs to compare their SM motives with other industries. A major difference found was the absence of motivation on the part of HEIs to use SM. This is in contradiction to other industries that put relationship building with customers as one of the primary motives to use SM.
