Dating common commodity price and inflation shocks with alternative approaches
Authors: Esposti Roberto
Published: July 2024

This paper investigates the occurrence of common price shocks (co-exceedance) across different commodities. IMF monthly price series of 11 commodities are considered over the 1980-2021 period. The analysis considers two alternative stochastic processes. The first looks for common volatility clusters using individual GARCH models to detect whether and when respective clusters overlap. Through an appropriate battery of tests, the second alternative looks for a common Bubble Generating Process (BGP) by searching for individual explosive roots and then dating them to identify the possible overlaps and first movers. Evidence emerging about these shock generating processes is linked to the analogous behaviour of the US Consumer Price Index (CPI) to assess to what extent inflation shocks can be associated to the observed commodity price spikes. Results show that the detection of temporary bubbles and volatility clusters only partially agrees on the episodes of exuberance, on the first-moving commodities and on the involvement of the CPI. This provides helpful suggestions on the development of a real-time surveillance tool supporting policy intervention in periods of commodity price turbulence.
Lessons learned and policy implications from 20 years of Swiss agricultural policy reforms: A review of policy evaluations
Authors: Huber Robert , El Benni Nadja , Finger Robert
Published: July 2024

Learning from the experiences of other countries can support efforts to improve agricultural policies. Switzerland provides an interesting case because its policy is exceptionally targeted towards the establishment of sustainable production systems. We describe the history and the current state of Swiss agricultural policy, review evaluations of policy reforms, summarise their impact and outline the lessons learned for policy developments in other countries. We discuss four implications: i) some goals have been met, albeit at a high cost, and so, increasing efficiency of policies is key; ii) there is a need for more coherence and coordination regarding the different policy programmes (i.e. in the sense of a ‘food system policy’); iii) cross-compliance measures (i.e. minimum standards for receiving support) have an important leverage effect; and iv) policy differentiation (e.g. by spatial targeting) and increasing farmers’ discretion over how to achieve goals (e.g. by implementing results-based payments) are key for future policies.
Navigating Consumer Behaviour: Exploring the Influence of Fashion Trends and Social Media on Gen Z and Millennial Consumption in West Java
Authors: Dewi Yasdiafiani , Indra Indra
Published: July 2024

Understanding consumer behaviour is crucial for assessing the economic well-being of individuals or households. However, with the advancement and modernization of society, individuals tend to impose their desires on consumption, leading to a consumeristic. This study investigates the impact of fashion trends and social media on consumption behavior among Generation Z and Millennials in West Java Province using partial least squares structural equation modeling (PLS-SEM). Primary data collected through surveys were analyzed. The results reveal that fashion trends significantly influence consumption behavior, while social media has a minimal impact. This suggests that efforts to reduce consumerism's impact should focus on addressing the influence of fashion trends. However, leveraging social media for educational campaigns promoting responsible consumption remains crucial.

Published: July 2024

Stroke is the second leading cause of death in the world and the third leading cause of disability, with incidence and prevalence increasing significantly. In Indonesia, the prevalence of stroke is high, mainly due to the lack of control of risk factors and slow adaptation to a healthy lifestyle after the attack. Stress is identified as one of the main factors that aggravate the physical condition and hinder the recovery process in stroke survivors. This community service aims to provide education about the healing environment method as an effort to control stress to prevent recurrent attacks in stroke survivors in Bangli Regency, Bali. This activity was carried out from December 2023 to January 2024, with a community service method in the form of education and demonstration for three days on how to create a healing environment that includes aspects of safety, physical and psychological comfort, social support, access to nature, art, music, and privacy which was attended by 20 stroke survivors. Results showed that the majority of participants had high blood pressure (80%) and normal blood glucose (85%). The increase in participants' knowledge about the healing environment was reflected in the pre-test results which showed 75% of participants had low knowledge, while the post-test showed an increase in sufficient knowledge in 80% of participants. This education helped participants recognize the factors that cause stress and manage stress effectively. The conclusion of this activity shows that the healing environment method can help reduce stress, accelerate recovery, and prevent recurrent stroke attacks. Thus, this method can improve the overall quality of life of stroke patients. The program emphasized the importance of a holistic approach that includes physical, psychological, social, and spiritual aspects to optimize the recovery of stroke patients and prevent further complications.

Published: July 2024

Resumo Fundamento A carga de fibrilação atrial (FA) é definida como a proporção de tempo que o paciente permanece em FA durante um determinado período de tempo; portanto, é teoricamente mais elevado na FA permanente e mais baixo na FA paroxística. A inflamação está associada ao início e à manutenção da FA. No entanto, a relação entre o índice de inflamação imune sistêmica (SII, do inglês systemic immune-inflammation index) e a carga de FA é desconhecida. Objetivo No presente estudo, investigamos a relação entre o SII e a carga de FA. Métodos O presente estudo é uma análise transversal de 453 pacientes (252 do sexo feminino e 201 do sexo masculino, com idade entre 44 e 94 anos) com FA (138 com FA paroxística e 315 com FA permanente) atendidos no ambulatório de cardiologia entre outubro de 2022 e junho de 2023. O SII foi calculado como (neutrófilos × plaquetas/linfócitos). O papel preditivo do SII e de outros marcadores inflamatórios na probabilidade do padrão de FA foi avaliado por análises de regressão logística, sendo considerado estatisticamente significativo o valor de p < 0,05. Resultados Idade, pressão arterial diastólica, frequência cardíaca, diabetes mellitus, neutrófilos, relação plaquetas-linfócitos, relação neutrófilos-linfócitos, SII, proteína C reativa, largura de distribuição de glóbulos vermelhos, hemoglobina A1c e diâmetro do átrio esquerdo foram significativamente maiores no grupo com FA permanente. De acordo com a análise de regressão logística, idade (p = 0,038), diabetes mellitus (p = 0,024), largura de distribuição de glóbulos vermelhos (p = 0,023), proteína C reativa (p = 0,010), SII (p = 0,001) e o diâmetro do átrio esquerdo (p < 0,001) contribuíram significativamente para a predição da probabilidade de FA permanente. Conclusão O SII está independentemente associado à carga de FA. Estudos prospectivos são necessários para determinar se o SII pode ser útil na identificação de pacientes com alto risco de progressão da FA.

Published: July 2024

Abstract Background Atrial fibrillation (AF) burden is defined as the proportion of time the patient remains in AF over a given period of time; thus, it is theoretically highest in permanent AF and lowest in paroxysmal AF. Inflammation is associated with the initiation and maintenance of AF. However, the relationship between systemic immune-inflammation index (SII) and AF burden is unknown. Objective In the present study, we investigated the relationship between SII and AF burden. Methods The present study is a cross-sectional analysis of 453 patients (252 females and 201 males, aged 44 to 94 years) with AF (138 with paroxysmal AF and 315 with permanent AF) who visited the cardiology outpatient clinic between October 2022 and June 2023. SII was calculated as (neutrophils × platelets/lymphocytes). The predictive role of SII and other inflammatory markers in the likelihood of AF pattern was evaluated by logistic regression analyses, and p value < 0.05 was considered statistically significant. Results Age, diastolic blood pressure, heart rate, diabetes mellitus, neutrophil, platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, SII, C-reactive protein, red blood cell distribution width, hemoglobin A1c, and left atrial diameter were significantly higher in the permanent AF group. According to the logistic regression analysis, age (p = 0.038), diabetes mellitus (p = 0.024), red blood cell distribution width (p = 0.023), C-reactive protein (p = 0.010), SII (p = 0.001), and left atrial diameter (p < 0.001) significantly contributed to the prediction of the likelihood of permanent AF. Conclusion SII is independently associated with the AF burden. Prospective studies are needed to determine whether SII may be useful in identifying patients at high risk for AF progression.

Published: July 2024

Resumo Fundamento: Gama-câmaras com detectores de telureto-cádmio-zinco (CZT) permitiram a quantificação da reserva de fluxo miocárdico (RFM), podendo aumentar a acurácia da cintilografia miocárdica de perfusão (CMP) para detectar a causa do desconforto torácico. Objetivo: Avaliar o impacto clínico da RFM para detectar a causa do desconforto torácico. Métodos: 171 pacientes com desconforto torácico que foram submetidos a coronariografia ou angiotomografia de coronárias também realizaram CMP e RFM num intervalo de tempo <30 dias. As aquisições das imagens dinâmicas de repouso e estresse foram iniciadas simultaneamente à injeção de 99mTc sestamibi (10 e 30mCi, respectivamente), ambas com duração de onze minutos, seguidas imediatamente pela aquisição das imagens de perfusão durante 5 minutos. O estresse foi realizado com dipiridamol. Uma RFM global ou por território coronariano <2,0 foi classificada como anormal. Resultados: A idade média foi de 65,9±10 anos (60% do sexo feminino). A avaliação anatômica mostrou que 115 (67,3%) pacientes apresentavam obstrução coronariana significativa, sendo que, 69 apresentavam CMP anormal e 91 apresentavam RFM anormal (60,0% vs. 79,1%, p<0,01). Dentre os pacientes sem obstrução (56 – 32,7%), 7 tinham CMP anormais e 23 tinham RFM global reduzida. A realização da RFM identificou a etiologia do desconforto torácico em 114 pacientes enquanto a CMP identificou em 76 (66,7% vs. 44,4%, p<0,001). Conclusão: A RFM é uma medida fisiológica quantificável que aumenta o impacto clínico da CMP na detecção da causa do desconforto torácico através de uma maior acurácia para detecção de DAC obstrutiva e ainda possibilita identificar a presença de doença microvascular.

Published: July 2024

Education plays a crucial role in the development of any country. All the sectors of the economy need at least qualified labour who can actively participate by upskilling and reskilling from time to time to stay competitive. Government should develop infrastructure for uniting all the stakeholders (companies of all kinds, education institutions and government bodies) of the labour market to collaborate better and effectively. Indian higher education institutions are producing young and dynamic labourers who are paying their contribution not only in the Indian economy but also globally. But still there is a large scope of improvement. There is a high unemployment rate among young people with advanced education, lack of workplace, outdated education programs, lack of popularity of reskilling and upskilling programs and so on. Government funding in gross expenditure research and development has been decreasing throughout the year, which creates obstacles for highly skilled specialists to find a better opportunity or competitive salary in India and exerts force on them to migrate to a better country providing such benefits. This article analyses the government spending in research and development, unemployment rate among youth and the problem faced by university graduates in the labour market which provide a deep understanding of the current situation of India’s highly qualified personnel. The purpose of the article is to identify the problems faced by highly qualified specialists in India. Objective: analyse India’s education sector; identify the impact of R&D expenditures on the development of the country; Identify the challenges faced by highly qualified professionals in India. Methodology. The article used the methods of generalisation, comparison and grouping by using the data published by national and international organisations as well as state bodies.

Published: July 2024

En el presente trabajo se presenta una metodología, basada en modelos de repuesta de la frecuencia, para estimar el valor mínimo o máximo -nadir- que alcanza la frecuencia cuando en el sistema eléctrico de potencia se presenta un desbalance generación – carga. Con este fin, se determina el modelo reducido de 1er orden del sistema de control potencia – frecuencia del generador usando el “Estimador de Parámetros” de Matlab/Simulink. Luego, se establecen ecuaciones que provienen del modelo equivalente reducido para estimar el valor de la máxima desviación transitoria de la frecuencia y su tiempo de ocurrencia. Para ilustrar la aplicación de la metodología presentada se ha elegido el sistema de prueba IEEE New England de 39 barras y 10 generadores. Hecho esto, la metodología propuesta se aplica al Sistema Nacional Interconectado ecuatoriano. Se presentan resultados de simulaciones en el dominio del tiempo usando el programa PowerFactory, mismos que son comparados con los resultados calculados mediante el modelo equivalente reducido y el modelo analítico. Se concluye que la metodología propuesta estima con alta precisión la máxima desviación transitoria de la frecuencia y su tiempo de ocurrencia.

El Ecuador actualmente se encuentra atravesando una complicada e inhóspita etapa de combate contra la delincuencia organizada, delito que según la ley penal se define como los grupos criminales destinados a la comisión de una variedad delitos para fines de lucro, pese a todas las regulaciones en la normativa y medidas adoptadas por el Estado para contrarrestarlos y de esta manera evitar que se siga poniendo en riesgo la seguridad social del país, estos no dejan de incrementarse. El objetivo de este trabajo es determinar las deficiencias y limites que presentan algunos elementos en la tipificación de este tipo penal que evitan esclarecer las piezas para que se configure este crimen. Con auxilio de los métodos histórico, comparativo, analítico, dogmático, entre otros, se arribó a la conclusión de que se presentan inexactitudes en los tipos penales de sujeto y acción y que adicionalmente estos grupos surgen a raíz de la corrupción y de entornos sociales bajos con limitantes educativos y económicos, que conllevan a que se forme este panorama de miedo e inseguridad en la sociedad.
“SONG” AS A LINGUAL-AND-AESTHETIC SIGN OF THE NATIONAL CULTURE IN THE DIARY TEXTS OF DIASPORA
Authors: SYRKO Iryna
Published: July 2024

The article deals with peculiarities of the lexical-and-semantic realization of the image song as a lingual-and-aesthetic feature of national culture in the diary discourse of Ukrainian diaspora. It has been emphasized that peculiarities of the diarists’ individual styles are determined by extralingual factors, in particular the diasporian worldview. The song often verbalizes their genetic memory, acts as a specific aesthetic category, a source of life and basis of national consciousness.
In the article the functioning of the image song in different trope structures has been traced. Its epithetization and metaphorization indicate the immersion of the diarists in the aesthetic essence of the national literature (both – the folk and the authorsʼ). Through the song, the authorsʼ feelings and moods related to the perception of the ethnic Motherland are most naturally conveyed. Their evaluation is clearly polarized into positive and negative. The traditional positive evaluation of the song is accentuated by its compatibility with the meanings native, beautiful, wonderful, etc. To emphasize its negative evaluation the authors often transcriptional reproduction of song lines according to the Russian phonetic prototype, reproduction of non-normative pronunciation, etc.
Diaspora diarists often interpret the national song as a source of information about Ukraine, its customs and traditions. It is associated with artistic and emotional memory of the people, a unifying and spiritually strengthening force.
The Ukrainian song, as a means of self-expression, finds confirmation in the use of song lines in diaristsʼ everyday speech, as they often think and speak using the song images.
Therefore, the image of a song in diaspora diary texts is conceptualized as an emotional-and-expressive code, a linguistic-and-aesthetic sign of national culture, a defining component of the authorsʼ worldview.

VOCABULARY OF FEMININE PERSONAL NAMES IN UKRAINIAN LITERARY LANGUAGE: BETWEEN NORM AND DESTRUCTION
Authors: KOTS Tetiana
Published: July 2024

The article examines the dynamics of word formation of names of persons of the feminine gender during the 20th and early 21st centuries. The trends of prescriptive and descriptive norms in connection with non-linguistic factors of different historical periods are clarified. The vocabulary of feminine nouns had signs of natural language development until the end of the 20th century and acquired threatening proportions in the last decade, which can lead to the destruction of the phonetic, morphonological structure of the word and the literary norm in general.
The issue of creating feminine names in the Ukrainian literary language has gained significant resonance in recent years. Among the reasons for its actualization, linguists cite the powerful socialization of modern women, their involvement in the spheres of “male” activity, state-building tendencies to assert national identity (“restoration” of the purity and authenticity of the language), the impact of the democratization of society on the literary standard. Language always responds to the demands of society and this is one of the drivers of its natural development, but provided that these changes correspond to its structural features, in the case of names of persons of the feminine gender, to the potential possibilities of word creation. As evidenced by language practice, this is the main and defining problem that can have not only negative, but also destructive consequences for the grammatical system in general. Any word-formation models are embedded in the language a priori, and have certain precedents throughout its historical development.
The creation of personal names has a long tradition in the Ukrainian language and is primarily based on the principles of the internal structure of the dictionary. The most important and unchanged for all generations of linguists were the instructions of the norm-makers of 20th century on the natural development of the language, which is decisive for its life activity as a whole. At the current stage of language functioning, the normativity of a word depends on its compliance with the phonetic and morphological structure of the Ukrainian lexicon and the lexical norm in general.

Nowadays, decreasing sources of petroleum fuel has led to innovation of other resources. Alternative fuel can be produced from biomass such as alcohol. In this work, an experimental study on the feasibility and the effects of using Diesel-ethanol and Diesel-methanol blends as alternative fuel for Diesel engine was carried out. Pure Diesel, Diesel-ethanol, D95E5, D90E10 and D85E15 as well as Diesel-methanol, D95M5, D90M10 and D85M15 on Farymann four stroke monocylinder Diesel engine performances was completed. The engine is tested at full load with engine speed ranged from 700 to 3000 tr/min. The effects of ethanol and methanol fraction on diesel engine power, torque, brake specific fuel consumption (BSFC), brake thermal efficiency and exhaust temperature were experimentally investigated. The results showed that mixing ethanol and methanol at different fractions with Diesel fuel have a significant effect on the engine performance, as well as the nature of alcohol, which constitutes a combustion catalyst. Fuel mixtures, D85E15 and D85M15 have the highest improvement rates compared to pure Diesel and other examined fuel mixtures. It has been shown, that, the lowest BSFC than that of pure Diesel, which is an advantage for our proposed fuels, is recorded with D95E5 and D95M5 blends. The different mixtures provide higher exhaust gas and outlet temperature of the coolant proportional to the mixing ratio, which explains why the addition of biofuel improves the calorific value of the fuel. The combustion of the different mixtures increases the outlet temperature of the coolant in proportion to the mixing rates.

HOUSING PRICE, FAMILY STRUCTURES AND HOUSEHOLD CONSUMPTION: EMPIRICAL EVIDENCE OF TAIWAN
Authors: Hung Chih-Hsing , Chen Yen-Hung , Cheng Chung-Chieh , Tzang Shyh-Weir
Published: July 2024

The housing price affects the allocation of family budget on consumption. We use regression analysis to confirm whether Taiwan’s housing prices have a significant influence on household consumption based on the questionnaire survey on household income and expenditure in 2018. We find that housing prices have the greatest impact on household consumption, possibly because housing accounts for the largest proportion of household assets, implying a significant wealth effect. In addition, the impact of interest of deposit on consumption is also found to be greater than that of household income as it is related to the level of total assets. The housing prices for single-person household with female gender have a negative and significant impact on household consumption. Finally, housing prices are found to have a significantly negative effect on non-consumption and current transfer expenditure. The possible reason is that the households who hold the house believe that the appreciation of housing price can provide more protection for the family from suffering from possible economic risks in the future and thus crowd out non-consumption expenditures.
On the Intermittency of Hot Plasma Loops in the Solar Corona
Authors: Judge Philip G. , Kuin N. Paul M.
Published: July 2024

A recent analysis has suggested that the heating of plasma loops in the solar corona depends not just on the Poynting flux but also on processes yet to be identified. This discovery reflects and refines earlier questions such as, Why and how are entire hydromagnetic structures only intermittently loaded with bright coronal plasma? The present work scrutinizes more chromospheric and coronal data, with the aim of finding reproducible observational constraints on coronal heating mechanisms. Six independent scans of chromospheric active-region magnetic fields are investigated and correlated to overlying hot plasma loops. For the first time, the footpoints of over 30 bright plasma loops are thus related to scalar proxies for the Poynting fluxes measured from the upper chromosphere. Although imperfect, the proxies all indicate a general lack of correlation between footpoint Poynting flux and loop brightness. Our findings consolidate the claim that unobserved physical processes are at work, which govern the heating of long-lived coronal loops.
Subjective life expectancies, time preference heterogeneity, and wealth inequality
Authors: Foltyn Richard , Olsson Jonna
Published: July 2024

This paper examines how objective and subjective heterogeneity in life expectancy affects savings behavior of healthy and unhealthy people. Using data from the Health and Retirement Study, we first document systematic biases in survival beliefs across self‐reported health: those in poor health not only have a shorter actual lifespan but also underestimate their remaining life time. To gauge the effect on savings behavior and wealth accumulation, we use an overlapping‐generations model where survival probabilities and beliefs evolve according to a health and survival process estimated from data. We conclude that differences in life expectancy are important to understand savings behavior, and that the belief biases, especially among the unhealthy, can explain up to a fifth of the observed health‐wealth gap.

Social scientists have long been interested in marital homogamy and its relationship with inequality. However, measuring homogamy is not straightforward, particularly when one is interested in assessing marital sorting based on multiple traits. In this paper, we argue that Separate Extreme Value (SEV) models not only generate a matching function with several desirable theoretical properties, but they are also suited for the study of multidimensional sorting. Specifically, we use rich small‐scale survey data to examine sorting among parents of school‐age children in Naples. We show that homogamy is pervasive; not only do men and women sort by age, education, and physical characteristics, but they also look for partners that share similar health‐related behavior and risk attitude. However, we also show that these marital patterns are well explained by a low number of dimensions, the most important being age cohort and human capital. In particular, human capital relates to various “outcomes” of the post‐matching relationship. Children of parents with a high human capital endowment perform better at school, although they report lower levels of subjective well‐being and of perceived quality of relationship with their mothers.
Changes in the span of systematic risk exposures
Authors: Liao Yuan , Todorov Viktor
Published: July 2024

We develop a test for deciding whether the linear spaces spanned by the factor exposures of a large cross‐section of assets toward latent systematic risk factors at two distinct points in time are the same. The test uses a panel of asset returns in local windows around the two time points. The asymptotic setup is of joint type: the number of assets and the number of return observations per asset increase asymptotically while the length of both time windows shrinks. We estimate the factor exposures, up to rotation, over the two periods using classical principal component analysis and evaluate their projection discrepancy, which is rotation invariant. This projection discrepancy is then centered with one between factor exposures computed over a partition of the pooled return data into odd and even increments. We derive the limit distribution of the statistic under the null hypothesis and develop an easy‐to‐implement bootstrap for constructing the critical region of the test. The test is applied to intraday financial data to determine whether the linear span of assets' systematic risk exposures differ during a trading day or after a release of important economic information.
A theory of fair random allocation under priorities
Authors: Han Xiang
Published: July 2024

In the allocation of indivisible objects under weak priorities, a common practice is to break the ties using a lottery and to randomize over deterministic mechanisms. Such randomizations usually lead to unfairness and inefficiency ex ante. We propose and study the concept of ex ante fairness for random allocations, extending some key results in the one‐sided and two‐sided matching markets. It is shown that the set of ex ante fair random allocations forms a complete and distributive lattice under first‐order stochastic‐dominance relations, and the agent‐optimal ex ante fair mechanism includes both the deferred acceptance algorithm and the probabilistic serial mechanism as special cases. Instead of randomizing over deterministic mechanisms, our mechanism is constructed using the division method, a new general way to construct random mechanisms from deterministic mechanisms. As additional applications, we demonstrate that several previous extensions of the probabilistic serial mechanism have their foundations in existing deterministic mechanisms.
The Beehive Metaphor in Blade Runner 2049
Authors: Borioli) Apian (Aladin
Published: July 2024

For the past four decades, digital sensing technology has slowly and slyly transformed our relationship with planet Earth, extending its synthetic tentacles into the most remote areas of our planet. Recently, it reached beehives and gave birth to Precision Beekeeping (PB). PB uses digital sensors to monitor bees with the aim of transforming beekeeping practices by maximising bee productivity and minimising beekeepers’ effort. However, this comes at the cost of exhausting an already-unbalanced relationship between humans and bees. Using the science-fiction film Blade Runner 2049 as guide, this essay explores Precision Beekeeping’s past, present, and potential futures. Ultimately, this text proposes to use digital sensing technology as a weapon, which if seized correctly could help develop post-capitalist beekeeping practices and socially-engaged relationships with the Earth.
Nomadic Time in Sarawak, Malaysia
Authors: Kendall Blake
Published: July 2024

In the face of the Planetary Emergency it feels like we spend a lot of time trying to sense make and make sense of speculative futures. Climate predictions, ramifications of 1.5 degree tipping points, and even a youth climate movement who dedicated their Fridays to reclaim their Future. It feels like our zeitgeist is playing a game of time travel. And as we collectively attempt to define and enact sustainability, there’s an inherent question we are learning to ask — what are the consequences of today on tomorrow? But time, just like space, is understood from different view points. In this article I offer some insights from collaborations between myself, Penan activists, musicians, communities and the camera — “the motor that allows you to see”. I want to explore how time is perceived, and how that can shift our notion of sustainability. Where dominant notions of linearity, mean we start at the beginning in order to reach an end, I’m interested in discussing alternate models of time, for not all of us view the land for its resources that can be exploited and accumulated for later use.Often in media coverage and academic representation, the Penan are recognised as the last nomadic peoples of South East Asia and I’m interested in what aspects continue, linger and inform the relationship between people and their ecology according to nomadic subsistence after the deforestation. When a culture does not permanently shift or alter the land, there are no infrastructural relics equating that there is “no evidence” of historic lineage of the first nation people’s claim to the land. Such is the case for Penan peoples in Sarawak, Malaysia who’s territories continue to be unrecognised. When so much has been destroyed, damaged or changed, what has been left behind?
Speculations and Survivals:
Authors: McLean Stuart
Published: July 2024

What role might an engagement with the past continue to play for an anthropology oriented toward the imagining and enacting of alternative (more just, livable, sustainable) futures? I approach this question via a “speculative memoir” of my own involvement in the Papay Gyro Nights Art Festival, held on the island of Papa Westray, Orkney (2011-2017). Founded by two emigré artist-curators (from Kyrgyzstan and Hong Kong), and featuring a range of contemporary artworks in a variety of media, the festival sought to engage elements from North Atlantic storytelling and performance traditions to explore alternative forms of collectivity, premised not on reactionary nostalgia or readymade criteria of inclusion and exclusion, but on an open-ended and experimental engagement between pasts and presents, humans and other-than-humans, including the singular materiality of the island setting.
Faust et le type de l’artiste dans les récits des années 1830 en France
Authors: Chaisemartin Amélie de
Published: July 2024

En 1830 en France, Faust est devenu un « type », ce qui signifie, d’après la définition donnée par Charles Nodier, un personnage littéraire célèbre, repris et imité par de nombreuses œuvres. Dans les romans français des années 1830, de nombreux personnages sont en effet inspirés de Faust. Cet article analyse la manière dont ces romans emploient ce type et le réinterprètent. Il montre que dans les années 1830 le type de Faust y symbolise la figure de l’artiste et ses contradictions.
Valorização turística da oliveira em Saint-Rémy de Provence: entre a requalificação simbólica e a deturpação dos valores patrimoniais
Authors: Deramond Julie , Grison Pauline , Triquet Eric
Published: July 2024

Este artigo analisa o estatuto da oliveira e dos seus produtos na promoção turística de Saint-Rémy de Provence, uma cidade da Provença emblemática de uma região olivícola. A partir da análise dos discursos icónicos baseados na utilização de imagens ligadas ao património olivícola, o estudo examina a hipótese de que a azeitona, o azeite e a oliveira têm sobretudo um valor emblemático como símbolos da Provença. O objetivo é mostrar que tais símbolos são utilizados sobretudo para fins comerciais e turísticos, para além de serem testemunhas de uma identidade cultural reivindicada.
The microadventure: a new or renewed kind of sports tourism?
Authors: Riffaud Thomas , Le Roux Nathalie
Published: July 2024

This article examines microadventuring in light of existing sports tourism research. The methodology used was qualitative, and ten semi-structured interviews were conducted. Results show the microadventure to be a marketing concept in sync with the changes currently happening to nature sports in today’s society, a fluidity that means it cannot be considered a new phenomenon. It is part of the changing relationship that humans have with nature, and how they use it for sporting purposes, and is rather an updating or revisiting of older forms of leisure in a contemporary context. Microadventurers have an idealised vision of nature, seeing it as a training ground filled with positive values, thus perpetuating representations. The self-organisation aspect and participant stances on ecology and image reflect how microadventuring aligns with the values and motivations of the most affluent sectors of the population.
Os Olivais da Andaluzia: Análise das dinâmicas patrimoniais, identitárias (habitantes) e turísticas no processo de inscrição na lista da UNESCO
Authors: Brianso Isabelle
Published: July 2024

Em Espanha, os olivais estão espalhados por quase todo o país, embora a maior concentração de olivais se encontre na Andaluzia. Cultivada desde tempos remotos, a olivicultura é hoje um sector económico altamente estratégico para esta região do sul da Península Ibérica. Este país defende uma candidatura à UNESCO cuja área de inscrição se estende, em parte, por um território denominado "el mar de olivos", formando uma paisagem de 70 milhões de oliveiras, o que faz dela a maior plantação de árvores da Europa. O desenvolvimento contemporâneo desta monocultura teve um impacto considerável nos modos de vida, na indústria local e no património cultural de várias cidades históricas andaluzas e estâncias turísticas (Granada, Córdova, Jaén), moldando a identidade cultural e social da região. Atualmente, o olival andaluz ultrapassou largamente a sua definição agrícola tradicional. De facto, este património imaterial e a sua preservação (saber-fazer e paisagem) desempenharam um papel crucial no reconhecimento, em termos de identidade e memória, reivindicado pelos habitantes durante o processo de registo. Este artigo analisa a dinâmica patrimonial desta paisagem olivícola para a UNESCO, bem como a participação dos habitantes locais durante o processo de inscrição e as alternativas turísticas (rotas) à margem das grandes cidades andaluzas classificadas como património mundial (Córdoba, Granada, Sevilha), com base nos documentos utilizados para a inscrição da candidatura na UNESCO.
