Resumen
AbstractThe authors tested face discrimination, face recognition, object discrimination, and object recognition in two face transplantation patients (FTPs) who had facial injury since infancy, a patient who had a facial surgery due to a recent wound, and two control subjects. In Experiment 1, the authors showed them original faces and morphed forms of those faces and asked them to rate the similarity between the two. In Experiment 2, they showed old, new, and implicit faces and asked whether they recognized them or not. In Experiment 3, they showed them original objects and morphed forms of those objects and asked them to rate the similarity between the two. In Experiment 4, they showed old, new, and implicit objects and asked whether they recognized them or not. Object discrimination and object recognition performance did not differ between the FTPs and the controls. However, the face discrimination performance of FTP2 and face recognition performance of the FTP1 were poorer than that of the controls were. Therefore, the authors concluded that the structure of the face might affect face processing.

Resumen
Perception of face parts on the basis of features is thought to be different from perception of whole faces, which is more based on configural information. Face context is also suggested to play an important role in face processing. To investigate how face context influences the early-stage perception of facial local parts, we used an oddball paradigm that tested perceptual stages of face processing rather than recognition. We recorded the event-related potentials (ERPs) elicited by whole faces and face parts presented in four conditions (upright-normal, upright-thatcherised, inverted-normal and inverted-thatcherised), as well as the ERPs elicited by non-face objects (whole houses and house parts) with corresponding conditions. The results showed that face context significantly affected the N170 with increased amplitudes and earlier peak latency for upright normal faces. Removing face context delayed the P1 latency but did not affect the P1 amplitude prominently for both upright and inverted normal faces. Across all conditions, neither the N170 nor the P1 was modulated by house context. The significant changes on the N170 and P1 components revealed that face context influences local part processing at the early stage of face processing and this context effect might be specific for face perception. We further suggested that perceptions of whole faces and face parts are functionally distinguished.

Resumen
Face perception is fundamental to human social interaction. Many different types of important information are visible in faces and the processes and mechanisms involved in extracting this information are complex and can be highly specialized. The importance of faces has long been recognized by a wide range of scientists. Importantly, the range of perspectives and techniques that this breadth has brought to face perception research has, in recent years, led to many important advances in our understanding of face processing. The articles in this issue on face perception each review a particular arena of interest in face perception, variously focusing on (i) the social aspects of face perception (attraction, recognition and emotion), (ii) the neural mechanisms underlying face perception (using brain scanning, patient data, direct stimulation of the brain, visual adaptation and single-cell recording), and (iii) comparative aspects of face perception (comparing adult human abilities with those of chimpanzees and children). Here, we introduce the central themes of the issue and present an overview of the articles.

Resumen
Objectives The purpose of this study was to fine out students’ perceptions in argument-based inquiry science classes in no-face-to-face and face-to-face situations. Methods For this purpose, 113 students from 4 classes in the 2nd year of middle school located in Matropolitan B were applied argument-based inquiry science classes in two different situations. Surweys and interviews were conducted and analyzed to fine out students’ perceptions of argument-ased inquiry science classes in each situations. Results As a result, there were differences in students’ perceptions of the class, perceptions of understanding scientific knowledge, and perceptions of self-activity regarding argument-based inquiry science in no face-to- face and face-to-face situations. First, in terms of students' perception of the class, students in no face-to-face situation actively participated in argument-based activities but students the other situation actively participated in the stage of actual activities. Second, students in no face-to-face situation the progress of the class remains as a record, and discussions using explanations using pictures and photos were helpful in understanding scientific knowledge. Unlike this, students in face-to-face situation good communication with the small group members helped to understand scientific knowledge. Third, in the perception of problem solving in discussion-based inquiry science classes in no face-to-face and face-to-face situations, students recognized that most of them contributed to solving inquiry problems through the argumentation. Conclusions This study examined students’ perception of learning in argument-based inquiry classes in two different situations, and this results were meaningful in exploring practical directions for successfully applying argument-based inquiry activities in various learning situations to school science classes.

Resumen
The appearance of faces can be strongly affected by the characteristics of faces viewed previously. These perceptual after-effects reflect processes of sensory adaptation that are found throughout the visual system, but which have been considered only relatively recently in the context of higher level perceptual judgements. In this review, we explore the consequences of adaptation for human face perception, and the implications of adaptation for understanding the neural-coding schemes underlying the visual representation of faces. The properties of face after-effects suggest that they, in part, reflect response changes at high and possibly face-specific levels of visual processing. Yet, the form of the after-effects and the norm-based codes that they point to show many parallels with the adaptations and functional organization that are thought to underlie the encoding of perceptual attributes like colour. The nature and basis for human colour vision have been studied extensively, and we draw on ideas and principles that have been developed to account for norms and normalization in colour vision to consider potential similarities and differences in the representation and adaptation of faces.

Resumen
A new facial composites technique is demonstrated, in which photographs of the top and bottom halves of different familiar faces fuse to form unfamiliar faces when aligned with each other. The perception of a novel configuration in such composite stimuli is sufficiently convincing to interfere with identification of the constituent parts (experiment 1), but this effect disappears when stimuli are inverted (experiment 2). Difficulty in identifying the parts of upright composites is found even for stimuli made from parts of unfamiliar faces that have only ever been encountered as face fragments (experiment 3). An equivalent effect is found for composites made from internal and external facial features of well-known people (experiment 4). These findings demonstrate the importance of configurational information in face perception, and that configurations are only properly perceived in upright faces.

Resumen
Adaptation to a face belonging to a facial category, such as expression, causes a subsequently neutral face to be perceived as belonging to an opposite facial category. This is referred to as the face aftereffect (FAE) (Leopold et al., 2001; Rhodes et al., 2004; Webster et al., 2004). The FAE is generally thought of as being a visual phenomenon. However, recent studies have shown that humans can haptically recognize a face (Kilgour and Lederman, 2002; Lederman et al., 2007). Here, I investigated whether FAEs could occur in haptic perception of faces. Three types of facial expressions (happy, sad and neutral) were generated using a computer-graphics software, and three-dimensional masks of these faces were made from epoxy-cured resin for use in the experiments. An adaptation facemask was positioned on the left side of a table in front of the participant, and a test facemask was placed on the right. During adaptation, participants haptically explored the adaptation facemask with their eyes closed for 20 s, after which they haptically explored the test facemask for 5 s. Participants were then requested to classify the test facemask as either happy or sad. The experiment was performed under two adaptation conditions: (1) with adaptation to a happy facemask and (2) with adaptation to a sad facemask. In both cases, the expression of the test facemask was neutral. The results indicate that adaptation to a haptic face that belongs to a specific facial expression causes a subsequently touched neutral face to be perceived as having the opposite facial expression, suggesting that FAEs can be observed in haptic perception of faces.

Resumen
While previous studies of face perception have focused mainly on the understanding of the processing of individual face cues, such as gaze direction, emotional expressions or physical attractiveness, some more recent studies suggest that these different cues are integrated in face processing.  The findings from the first four experimental Chapters in this thesis present further evidence for complex interactions among different invariant physical cues and changeable social cues when processing faces.  Importantly, these studies also demonstrate sources of systematic variation that modulate the manner in which this integration occurs (e.g., effects of changes in women’s progesterone levels, or differences among individuals high and low in anxiety).  The final experiment Chapter reports a series of experiments showing that rapid transient pupil constrictions to faces are sensitive to parameters such as the species and orientation of face.  These latter findings reveal transient pupil constrictions as a useful non-invasive and involuntary measure of face processing.  Collectively, the findings reported in this thesis demonstrate that cues to the direction and valence of others’ social interest, in addition to physical cues to attractiveness, are integrated when processing faces, highlighting the complexity and sophistication of the integrative processes that underpin face perception.

Resumen
I volti e i corpi veicolano gli indizi non-verbali più importanti per le interazioni sociali. Essi forniscono numerosi dettagli essenziali per il riconoscimento dell’identità, genere, intenzioni e stato emotivo. Tutti i volti e i corpi sono simmetrici e condividono la medesima struttura tridimensionale, ma gli esseri umani riescono ad identificare facilmente centinaia di persone diverse, facendo affidamento solo sulle informazioni fornite da volto e corpo. L’elaborazione del volto e del corpo è stata ampiamente studiata e diversi modelli cogntivi e neuroanatomici sono stati ideati per spiegare questi processi. Nonostante numerose differenze sostanziali, tutti questi modelli hanno riconosciuto diversi stadi di elaborazione, dalla codifica dello stimolo rapida e più grezza (corteccia visiva occipitale) fino a processi di livello più alto, finalizzati al riconoscimento di aspetti invarianti (es., identità) e mutevoli (es., sguardo, espressioni emotive) (sottesi da un vasto network fronto-temporo-parietale). È stato dimostrato che questi processi coinvolgono l’elaborazione configurale degli stimoli. Inoltre, le espressioni emotive sembrano influenzare la codifica di questi stimoli. Le espressioni emotive vengono elaborate ad uno stadio molto precoce e pare che coinvolgano l’attivazione di una via sottocorticale. Gli studi presentati in questa tesi hanno l’obiettivo di indagare la percezione visiva di volti e corpi, e come essa può essere modulata o manipolata, in alcuni studi anche attraverso l’elettroencefalografia (EEG). Mentre il primo Capitolo presenta il quadro teorico in cui è stato concepito questo lavoro di tesi, il secondo Capitolo presenta il primo studio (composto da due esperimenti), che ha l’obiettivo di indagare come può essere modulata la percezione di indizi sociali attraverso l’esclusione sociale. La ricerca era concentrata sulla percezione di due categorie di indizi facciali diversi, ma in interazione: le espressioni emotive e la direzione dello sguardo. In questo studio, abbiamo trovato che il riconoscimento della direzione dello sguardo veniva indebolita in modo specifico, mentre il riconoscimento delle espressioni emotive non era compromesso. I risultati di questo studio hanno portato a riflessioni importanti sull’importanza dello sguardo in quanto segnale di potenziale re-inclusione, e su come l’indebolimento dell’elaborazione dello sguardo potesse portare nuovamente all’esclusione sociale. Il terzo Capitolo presenta una meta-analisi sul body-inversion effect, una manipolazione che ha lo scopo di dimostrare l’elaborazione configurale dei corpi. Con la meta-analisi è stata indagata la coerenza e la dimensione di questo effetto, fondamentale nello studio della codifica strutturale dei corpi. Nel quarto capitolo, viene presentato uno studio sulle oscillazioni neurali coinvolte negli effetti di face- e body-inversion. Le oscillazioni sono state misurate nelle bande di attività theta e gamma attraverso l’EEG, dal momento che rappresentano un mezzo notevole per indagare l’attività psicofsiologica coinvolta in diversi processi. I risultati di questo studio hanno mostrato che l’elaborazione configurale di volti e corpi coinvolge meccanismi percettivi diversi. Nel quinto Capitolo viene presentato uno studio che indaga l’influenza dell’inversione e delle espressioni emotive nella codifica di volti e corpi. I correlati neurali di questi processi sono stati indagati attraverso i potenziali evento-correlati (ERPs). I risultati hanno evidenziato che sia l’inversione che l’espressione emotiva influenzavano l’elaborazione di questi stimoli, durante diversi stadi e attraverso diversi processi, ma queste due manipolazioni non interagivano. Pertanto, sembra che le informazioni configurali e le espressioni emotive siano elaborate attraverso processi percettivi indipendenti e che non interagiscono.
Human face and body convey the most important non-verbal cues for social interactions. Face and body provide numerous cues essential for recognition of other people’s identity, gender, age, intentions and emotional state. All faces and bodies are symmetrical and share a common 3D structure, but humans are able to easily identify hundreds of different people, just relying on facial and bodily information. Face and body processing have been widely studied and several cognitive and neuroanatomical models of these processes were hypothesized. Despite many critical differences, all these models recognized different stages of processing from early coarse stimulus encoding (occipital visual cortices) to higher-level processes aimed to identify invariant (e.g., identity) and changeable features (e.g., gaze, emotional expressions) (broad fronto-temporo-parietal network). It was demonstrated that these processes involve configural processing. Moreover, emotional expressions seem to influence the encoding of these stimuli. Processing of emotional expressions occurs at very early latencies and seems to involve the activation of a subcortical pathway. The studies presented in this thesis are aimed to investigate the visual perception of faces and bodies, and how it can be modulated or manipulated. EEG was used in some of the studies presented in this thesis to investigate the psychophysiological processes involved in face and body perception. While the first Chapter is aimed to present the theoretical background of the studies reported in the thesis, the second Chapter presents the first study (composed of two experiments), aimed to investigate how the perception of social cues can be modulated by social exclusion. The process investigated is the perception of two different, but interacting, facial cues: emotional expression and gaze direction. In this study, we found that the identification of gaze direction was specifically impaired by social exclusion, while no impairment was found for emotional expression recognition. The results of this study brought important insights concerning the relevance of gaze as a signal of potential re-inclusion, and how the impaired processing of gaze direction may reiterate social exclusion. The third Chapter presents a meta-analytic review on the body inversion effect, a manipulation aimed to demonstrate configural processing of bodies. This meta-analysis was aimed to investigate consistency and size of this effect, fundamental in studying structural encoding of body shapes. In the fourth Chapter, a study on the neural oscillations involved in face and body inversion effects is presented. Neural oscillations in theta and gamma bands were measured by means of the EEG since they are a very influential measure to investigate the psychophysiological activity involved in different processes. The results of this study showed that configural processing of faces and bodies involve different perceptual mechanisms. In the fifth Chapter, a study investigating the influence of inversion and emotional expression on the visual encoding of faces and bodies is presented. The neural correlates of these processes were investigated by means of event-related potentials (ERPs). Both inversion and emotional expressions were shown to influence the processing of these stimuli, during different stages and through different perceptual mechanisms, but results revealed that these two manipulations were not interacting. Therefore, configural information and emotional expressions seem to be processed through independent and non-interacting perceptual processes.

Resumen
Previous research has shown that deliberate disguise deteriorates human and automatic face recognition, with consequences for person identification in criminal situations. Common forms of deliberate disguise (e.g. balaclavas or hoodies) are easy to detect. When such disguises are used, viewer can distinguish between an unmasked individual - whose identity they knowingly can observe from facial appearance - and a masked individual - whose identity they knowingly cannot. Hyper-realistic silicone masks change this. Their recent use in criminal settings suggests that they effectively disguise identity and are difficult to detect. In this thesis, I first show that viewers are strikingly poor at distinguishing hyper-realistic masks from real faces under live and photographic test conditions, and are worse in other-race conditions. I also show large individual differences in discriminating realistic masks from real faces (5%-100% accuracy), and use an image analysis to isolate information that high performers use for effective categorisation. The analysis reveals an informative region directly below the eyes, which is used by high performers but not low performers. These findings point to selection and training as routes to improved mask detection. Second, I examine the reliability of estimates made of the person beneath the mask. Demographic profiling and social character estimates are poor, and results show that recognition rates were only just above chance, even for familiar viewers. This analysis highlights a systematic bias in these estimates: demographics, traits and social characteristics of the mask were attributed to those of the wearer. This bias has theoretical and applied consequences. First, it supports the automaticity with which viewers use a face to judge a person, even when they know the face is not that of the person. Second, it suggests that predictions of the person underneath the mask, by familiar and unfamiliar viewers alike, should be treated with great caution.

Resumen
Face perception and identification is a task done routinely by all of us. Considerable research has been carried out psychophysically on the detection and identification of human face and sophisticated models have been developed [2]. A critical issue in processing human faces in a machine vision system is the representation of a face since this determines the amount of storage of facial image. In general, a common technique is storing a 2-dimensional array of intensity values as an image file and then compressing the image (e.g. GIF, JPEG compression standards). It is also possible to degrade the image to lower spatial and grayscale resolution. However, at some point reducing resolution (number of pixel blocks) will be counterproductive due to significant loss of information. Here, we report the results of systematic and extensive psychophysical experiments to determine the precise limits of resolution (both spatial and grayscale) for face perception.

Resumen
We conduct a randomized controlled trial in Mexico City to determine willingness to pay (WTP) for SMS air quality alerts and to study the effects of air quality alerts, reminders, and a reusable N95 mask on air pollution information and avoidance behavior. At baseline, we elicit WTP for the alerts service after revealing whether the household will receive an N95 mask and participant compensation, but before revealing whether they will receive alert or reminder services. While we observe no significant impact of mask provision on WTP, higher compensation increases WTP, suggesting a possible cash-on-hand constraint. The perception of high pollution days prior to the survey is positively correlated with WTP, but the presence of actual high pollution days is not correlated with WTP. Follow-up survey data demonstrate that the alerts treatment increases reporting of receiving air pollution information via SMS, a high pollution day in the past week, and staying indoors on the most recent perceived high pollution day. However, we observe no significant effect on the ability to correctly identify which specific days had high pollution. Similarly, households that received an N95 mask are more likely to report utilizing a mask with filter in the past two weeks, but we observe no effect on using a filter mask on the specific days with high particulate matter. Although we nd that air quality alerts increased the salience of air quality and avoidance behavior, these results illustrate the difficulty that information treatments face in overcoming perceptions to effectively reduce exposure to air pollution.

Resumen
E-learning is the use of the internet and ICT to access learning material, interact with the content, instructor, and learners, and acquire knowledge. Education has grown rapidly and transformed the present isolated, teacher-center face-to-face education into online. Despite the impact of e-Learning, there are many challenges in adopting and implementing it in higher education. Therefore, the main purpose of the study was to investigate the perspective of lectures, challenges, and opportunities of adopting online learning. The study conducted institutional-based mixed quantitative and qualitative study designs at the University of Gondar from June to October 2022. Simple random sampling techniques were employed to select study participants for the quantitative study and purposive sampling was used to select higher officials for an in-depth interview. A structured self-administered and in-depth interview guide questionnaire was used for the quantitative and qualitative data respectfully. Linear regression analysis conducted for the quantitative data while inductive thematic analysis was undertaken for the qualitative data. Thirteen (13) higher officials were involved in an in-depth interview and 366 instructors participated in the quantitative study. The majority of participants believed that e-Learning is applicable. However, almost all participants agreed that the infrastructures are inadequate at the University of Gondar. Five main themes emerged from an inductive thematic analysis which includes: perceptions of adopting online learning, challenges of adopting online learning, opportunities of adopting online learning, strategies to overcome challenges, and higher officials’ willingness and support. Most instructors and all higher officials are willing and happy to adopt. Internet connectivity, electric power, computer access, and poor perception of instructors, students, and employees will be a challenge to adopting e-Learning. Capacity-building training for the instructors and supporting teams and fulfilling infrastructures for the successful implementation of e-Learning at the University of Gondar is recommended.

Resumen
Studies have shown that the United Arab Emirates (UAE) has some of the highest electricity and water consumption rates in the world. To understand the barriers to the adoption of energy and water efficiency, Emirates Wildlife Society in association with the World Wildlife Fund conducted 363 face-to-face interviews with representatives of companies tasked with energy and water management. The purpose was to understand the most important barriers hindering the UAE’s private sector from achieving wide-scale energy and water efficiency and to begin to identify solutions to mitigate these barriers. This paper focuses on technology costs as a barrier to energy and water efficiency in the commercial sector. Preliminary analysis indicates that, for the commercial sector, a contributing factor to the perception that efficient technologies are costly is the lack of accurate information on the full range and life cycle costs and benefits of efficient products. The most immediate solutions would be to address the financing and informational aspects of the technology cost barrier, as well as potentially provide incentives, such as rebates. In addition, attention must be given to barriers underlying many of the technology cost issues, such as subsidized tariffs and relatively few standards that would encourage adoption.

Resumen
Distance education has become the mandatory component of higher education establishments all over the world including Ukraine regarding COVID-19 lockdown and intentions of Universities to render valuable knowledge and provide safe educational experience for students. The present study aimed to explore the student’s and academic staff’s attitude towards e-learning and the most complicated challenges regarding online learning and distance education. Our findings disclosed that the online learning using Zoom, Moodle, Google Meet, BigBlueButton and Cisco has become quite popular among the students and academic staff in Ukraine in time of the lockdown period and beyond. Based on the Principal Component Analysis data processing we can conclude that students’ satisfaction and positive e-learning perception are in a good correlation with quality of e-learning resources and set of apps which are used while e-learning and distance education. Also, education style, methods, and manner predict willingness of students to self-study. The self-motivation, time-management, lack of practice, digital alienation, positive attitude towards ICT, and instruction strategy belong to the most important challenges of COVID-19 lockdown based on the students and academic staff interviews. Online learning on daily purpose should be used in the favor of strengthening of classical higher education rather than replacing the former. Blended education is the best alternative to face-to-face education, because the communication with mentor in a live environmental even virtual should have ushered the learners to complete online learning and improve its results.

Resumen
The COVID-19 pandemic outbreak affected most universities, and it severely disrupted their face-to-face teaching and learning processes. The University of Gondar (UoG) and the University of Rwanda (UR) were no exceptions. Before the pandemic, E-learning was not an education norm in both institutions. Education was mainly face-to-face, inside a four-wall classroom experience. As COVID-19 restricted such experience, the two universities adopted a range of online platforms to support teaching, learning, and access to learning resources. Across the globe, E-learning solutions promise institutional resilience and innovative teaching and learning activities in tertiary education – but only if their development is embedded within enabling institutional culture, structure, policy, and processes. Against this backdrop, we designed a study to explore leadership and policy perspectives, institutional contexts, potentials/prospects, challenges, and best practices of educational digital solutions. In this exploratory study, we used accessibility and inclusivity as key motifs to frame discussions of results. We used a cross-sectional design and employed qualitative methods to collect data, i.e., document reviews, key informant interviews, and focus group discussions. We adopted a descriptive thematic analysis procedure to organize, analyze, and interpret the data. Overall, the results indicate that education leaders, faculty, and students were not equipped to smoothly transition from face-to-face learning to e-learning in the aftermath of the COVID-19 pandemic. Not only meeting technological requirements, the accelerated deployment of E-learning tools implied a change in pedagogy. We found that institutional policies were not designed to fully accommodate the change (except for some guidelines proposed during COVID-19). The lack of an e-learning strategy and resource limitations have hindered and continue to impact e-learning uptake in both institutions. We also found that poor internet connectivity, lack of tech devices and software, inadequate leadership commitment, power interruptions or outages, inadequate pedagogical training, low community perception, and poor administrative and technical skills are the challenges of the two institutions to effectively manage full-fledged e-learning programs. These challenges were usually amplified by the nature of national, local, and institutional contexts (e.g., a multi-campus, multi-college setting of UR and a war outbreak in northern Ethiopia). Noting that face-to-face education is still seen as premium, there is a need for a blended approach to e-learning and policies that would improve accessibility to and affordability of E-resources to diverse groups of staff and students. With varying degrees, we found that the two institutions are engaging in activities to promote e-learning. For instance, groups of e-learning Champions are advocating in both institutions for engagements in accelerated change efforts (be it on an e-learning platform, capacity building, access devices, and strategy). Both institutions have units that coordinate e-learning uptake and ensure its inclusivity. Both institutions could also benefit from increased governmental and development partners’ attention to the possibility and support of digital education. However, the issue of social equity and e-learning ecosystem management remains paramount in launching e-learning programs. In sum, we observed that e-learning is still in its nascent stages at both institutions although not at the same level. Their respective e-learning initiatives must integrate global best practices and specific local contexts and priorities. This requires that state and institutional leaders embrace and encourage co-creation, knowledge, and expertise sharing among institutions in low-resource and similar settings.

Resumen
A growing number of countries are committed toreduce their carbon emissions and are transitioning towards renewable and clean energy sources, leading to an in crease in demand formetals and minerals. This is especially the case for a short list of what are called "critical minerals" which are considered essential to economic development, including the transition to a low-carbon economy and national security. There liability of their supply chain raises concerns considering geological scarcity, difficulty to extract and/or political factors influencing their availability. At the same time, public awareness and perception of geoscience are eroding and there is more and more reluctance towards mining projects, even from traditionally favourable communities. To face this challenge, promote public interest and outline the contribution of geological science to society, geoscientists of the Geological Survey of Canada (GSC-Québec) have designed and put together a portable display that includes a suite of mineral and metal samples considered critical for the sustainable success of Canada's transition towards a clean and digital economy. The display is a user-friendly toolkit that can be used by any GSC geoscientists during outreach activities, in classrooms as well as during public open houses. It comes with straightforward pedagogic material and content, along with presentation scenarios. To broaden and adapt the workshops to specific expectations, additional toolkits were developed and all are contained within easy to carry travel cases. These cover a variety of topics and can be presented as stand-alone displays or be used complementary to one another. For example, the "Mines and minerals" collection may serve as a supplement to the "Critical minerals" display to present every day objects in which minerals are used as well as ores amples from active mines to illustrate the intertwining between mining activities and our everyday lives. Another display covers the ever-popular fossils thematic with the "Sedimentary rocks and fossils" collection and gives an opportunity to address key geoscience themes such as life evolution and biological crisis along with groundwater reservoirs and resources. The "Magmatic rocks" display touches on the formation of rocks from magmas, the different types and active processes of volcanoes, and discusses the risks and benefits related to volcanic activity. Hopefully, these four ready-to-use portable displays will encourage more GSC geoscientists to engage in public oriented activities to make geosciences more accessible, change perceptions and offer an overall tangible scientific experience for people.

Resumen
The main contribution of this paper with respect to previous work is the use of data on subjective perceptions to identify the Latin American middle classes. This paper provides a set of comparisons between objective and subjective definitions of middle-class using data from the 2007 World Gallup Poll. Seven objective income-based definitions of social class are contrasted with a self-perceived social status measure. Mismatches between the objective and the subjective classification of social class are the largest when the objective definition is based on median incomes. Mismatches result from the fact that self-perceived social status is associated not just with income, but also with personal capabilities, interpersonal relations, financial and material assets, and perceptions of economic insecurity. Objective definitions of the middle class based on absolute incomes provide the lowest mismatches and the most accurate differentiation of the middle class from other classes.
