Cuaderno (etno)gráfico

The purpose of this essay is to present and reflect on the creation of an «(ethno)graphic notebook» based on a master's research on the uses and meanings attributed to instruments with wheels (handcarts, loading carts, refrigerator carts, warehouse carts, supermarket carts, etc.), in and around a public market (Velame, 2023) in João Pessoa-PB, Brazil. Between 2021 and 2023, drawings, photo collages and paintings were produced, forming a visual ethnography of the «carrinhos» present in the lives of various social actors. This essay reflects on the creative, imaginative and data organization processes in the construction of this drawn (ethno)graphy, exploring a visual perspective on the wheelbarrows and their narratives. The work is enriched by methodological techniques, standing out for the «critical and dense description» (Tsing, 2019; Geertz, 2015), adopting an ethnographic approach focused on the «art of seeing, art of being, art of writing» (Winkin, 1998).

Effects of Pulverized Madre De Cacao (Gliricidia sepium) and Jackfruit (Artocarpus heterophyllus) leaves as Saba Banana (Musa acuminata × balbisiana) ripening agents

In the Philippines, demand for fruits led to use of artificial ripening techniques like calcium carbide. These techniques contribute to meeting the rising demand for fruits but the fruits that benefit human health turned to unhealthy since the techniques affect the fruit's essential nutrients. This study provides an alternative organic ripening agent to saba banana for its healthy way of cultivation. It aims to determine the effects of pulverized Madre De Cacao and Jackfruit leaves on the duration of ripening, color, odor, palatability, and texture of saba banana and to determine the significant difference between pulverized Madre De Cacao and Jackfruit leaves, and the combination of pulverized leaves as ripening agents. Experimental research design applied wherein three concentrations observed in five days after applying to saba banana. The most effective organic ripening agent was utilized in the public market. The 15 respondents divided into three groups utilized different treatments and answered the questionnaires. The results revealed, treatment 2 (pulverized Jackfruit leaves) was most effective. The saba banana ripened in two days, color of peel turned yellow with green tips, odor of the banana smelled fragrant and fruity, palatability tasted enhanced sweetness, and texture when eaten was soft and creamy. On the other hand, treatment 1 (pulverized Madre De Cacao leaves) was next to most effective, and treatment 3 (combination of the two leaves) was slightly effective in some parameters. Further studies should be conducted on popular methods of ripening fruit such as the liquid method but in an organic way.

Hedge Fund Returns and Total Factor Productivity

This study explores whether hedge funds’ investment behavior can predict variations in productivity levels using a structural vector autoregressive model (SVAR) and a vector error correction model (VECM). As <i>informed</i> traders in the stock market with superior skills, hedge funds may quickly capture news shocks regarding future production growth in advance. With quarterly series of <i>TFP</i> provided by John Fernald (2014) and hedge fund index (<i>HFI</i>) returns obtained from the Credit Suisse/Tremont database, I find a contemporaneous correlation coefficient of 0.9791 between two endogenous variables over the sample period from 1Q:1994 to 2Q:2023, indicating a high degree of similarity in their movements. A Granger Causality Test rejects the hypothesis, “ ΔLn(<i>HFI</i>) does not Granger Cause Δ<i>TFP</i>”, suggesting that the information inferred from the hedge fund index are valuable in predicting future economic productivity. Finally, the forecast error variance decompositions using the VECM model indicate that over 65% of the variation in Δ<i>TFP</i> even after 20 quarters can be attributed to a shock to the Δ<i>Ln</i>(<i>HFI</i>) .

Changing Role of HR Manager in Global Market Place

Abstract: Research on "Management of Expatriates" is in its early stages. The challenge of preparing expatriate managers to serve as a bridge between parent and subsidiary firms and to thrive in different cultural contexts has emerged as an extra consequence of globalisation for many organisations. Hiring people from all over the world adds another layer of complexity to company cultures. There is a vast array of ethnicities, languages, and cultures represented among these people. Managers tasked with managing teams abroad should receive training to help them navigate cultural differences. An "expat" can be a manager from one nation whose home country's parent company sends them to live and work in another country. Proper training is vital if the expatriates are to succeed in their new surroundings and contribute to the organization's objectives. When employees participate in effective expatriate training courses, they may be better able to handle the challenges and stresses of cultural adaptation. Before, during, and after an assignment, participants get cultural training on subjects such home culture work and living in a host country. It could be more crucial to adjust to a different culture than to completely embrace it. The value of expat assignments is well-known by every prosperous business. By sending employees to work in other countries, a parent firm may help its subsidiaries run more smoothly. When travelling, a person's mindset and behaviour may diverge significantly from their home country. A company runs the risk of creating costly and unsolvable issues if it just talks to locals. By placing an expat onsite, cultural friction can be reduced. also, there are locations on every continent. Quality and safety standards may differ substantially from one country to another. Businesses may respond to client problems more quickly and individually when they hire personnel from different nations. While working overseas, an expat would have absorbed the values and norms of their home firm. Companies now value Expatiate Management. Management and training are two of the main reasons why expats fail.

Artificial Intelligence and Machine Learning in Financial Services: Risk Management and Fraud Detection

The field of financial risk management is undergoing a significant transformation due to the advancements in artificial intelligence (AI) and the underlying machine learning (ML) techniques that provide the foundation of AI. These developments hold the potential to revolutionize the way the user’s approach and address financial risk. The expansion of AI-driven solutions has opened up various opportunities for comprehending and managing risk. These opportunities encompass a wide range of activities, such as determining appropriate lending amounts for customers in banking, issuing warning signals to financial market traders regarding position risk, identifying instances of customer and insider fraud, enhancing compliance efforts, and mitigating model risk. The prime objective of this study is to investigate the application of AI and ML in the Financial Services industry, with a specific focus on Risk Management and Fraud Detection. This study proposes an intelligent and distributed approach for detecting Internet financial fraud using Big Data. The methodology entails the utilization of the graph embedding algorithm Node2Vec for the purpose of acquiring knowledge and representing the structural characteristics of the financial network graph in the form of compact vectors with reduced dimensions. This facilitates the intelligent and effective categorization and forecasting of data samples from a dataset of significant magnitude through the utilization of a deep neural network. Based on the study's findings, it was observed that the F1-Score test outcomes obtained from the Node2Vec algorithm range from 67.1% to 73.4%. These results surpass the outcomes achieved by the other two algorithms used for comparison. This finding demonstrates that Node2Vec has greater stability in terms of overall performance and yields superior categorization outcomes.

Smallholder farmers’ dissatisfaction with contract farming: a gendered perspective

ABSTRACT This study investigates the drivers of farmers’ dissatisfaction with market-specification contracts for finger millet crop in Kenya. The researcher analysed data from 336 farmers contracted by USOMI, out of which a sub-sample of 146 farmers who grew millet in 2021 was analysed using a probit model and descriptive analysis approach, which showed that asymmetric information related to the role of the contracting firm, lack of adequate understanding of the contract, poor pricing, and input market imperfections are some of the critical constraints and sources of dissatisfaction in the commercialisation of millet farming in Western Kenya. On the other hand, farmers’ satisfaction is driven by access to market and reasonable prices offered by the spot market traders. While the study found out that productivity and pricing were not gendered, it was observed that women were generally satisfied with contract farming. Consequently, contractual schemes should integrate complementary factors such as input provision. While the results do not show explicit benefits to women farmers, they do allow for the backing of contract farming in rural development programs to reduce gender inequalities.

Impact of economic policy uncertainty on global carbon emissions

The article aims to examine the potential effect of Economic Policy Uncertainty (EPU) on the mean and variance of carbon (CO2) emissions by employing a novel nonparametric causality-in-quantiles and quantile-on-quantile on the dataset comprising of 17 economies to test our hypothesis. The results of causality-in-quantiles find that EPU offers a significant yet mixed ability to impact the carbon emissions of most economies. These mixed patterns of impact pertain not only to mean and variance but also across regions. The results of quantile-on-quantile reveal that high EPU leads to an augmented level of carbon emissions. This causality may indicate that macroeconomic and institutional factors influence the carbon emission for all analyzed countries. These findings are particularly useful for practitioners, policymakers, academic researchers, and traders in the carbon market as they could promote the realization of carbon reductions targets by maintaining stable economic policies that have tangible ramifications for carbon emissions behavior.

Exploring the relationship between Chinese crude oil futures market efficiency and market micro characteristics

This paper uses daily frequency data spanning from March 26, 2018 to February 3, 2023, and combines the exponential generalized autoregressive conditional heteroskedasticity in mean (EGARCH-M) model with the time-varying parameters state-space (TVPSS) model to dynamically test the efficiency of the Chinese crude oil futures market (CCOFM). Additionally, the paper examines the relationship between market efficiency and market micro characteristics such as market depth, market liquidity, noise trading, speculation rate, and information asymmetry. The results show that the CCOFM exhibited weak-form efficiency in June 2020, which lasted until the end of February 2022, and after that, the efficiency showed a poor development trend. Analyzed from the macro level, the Market Maker System and Trader Suitability System have a positive effect on market efficiency, while the Russian-Ukrainian conflict has a negative effect on market efficiency. Analyzed from the micro level, market depth and information asymmetry have a positive effect on market efficiency, while the speculation rate has a negative effect on market efficiency, and noise trading and market liquidity have no significant effect on market efficiency. Market efficiency has a positive effect on market depth and a negative effect on speculation rate. Market liquidity and noise trading have a positive effect on speculation rate, while both information asymmetry and market liquidity have a negative effect on noise trading. In addition, speculation rate has a weak negative effect on information asymmetry, and market depth and speculation rate have a weak positive effect on market liquidity. This study provides theoretical support and decision-making foundation for the development of CCOFM by dynamically exploring the relationship between CCOFM efficiency and micro characteristics.

Потребительское поведение российской молодёжи в условиях санкций

The article delves into the phenomenon of consumer behavior of young people in the context of a new eco-nomic reality formed by the introduction of several packages of economic sanctions and a number of related adverse factors which form a new way of thinking among young people, which directly affects consumer be-havior, and therefore it is important for manufacturers to take into account these changes. The author analyzes approaches to the study of consumer behavior from the point of view of economic theory, sociology and psy-chology. The features of youth as a specific socio-demographic group are considered. The results of sociologi-cal and marketing research are presented as an evidence base. Conclusions are drawn about the continuing strategy of rational consumption, the growing share of online purchases, the increasing role of market places, the demand of young people for eco-friendly products and ethical brands based on the principle of “healthy for me and for the environment”.

The Stakeholders’ Perception on the Development of Baguio City Public Market

The development of Baguio City Public Market (BCPM) is awarded to SM Prime Holdings Incorporation (SMPHI) by the City of Baguio headed by Mayor Benjamin Magalong. Thus, the researcher aimed to understand and describe the perceived awareness of the active stakeholders participating in this development. As such, the researcher attempts to establish how the different stakeholders response to the development of BCPM using qualitative content analysis. Several online publications were subjected to analysis which provided the researcher the needed data. Thus, the paper identified five active stakeholders which are BCPM Vendors/ Baguio Market Vendor Groups, The Local Citizen, Tongtongan ti umili (TTU), Media Groups and Tourists. These stakeholders all possess power, legitimacy and urgency. The stakeholders’ perceived awareness revolves on the idea that there is a development undergoing in BCPM, specifically the stakeholders believe in two opposing ideas. First, the development is in good hand as the stakeholders support the action of the City Mayor. Second, the stakeholders think that the city’s socio- cultural and environment aspect is again threatened because of the participation of a big corporation which is the SMPHI.

What Makes HFTs Tick? Tick Size Changes and Information Advantage in a Market with Fast and Slow Traders

We study the impact of two changes in the minimum tick size, a reduction and a subsequent increase, on the trading behavior of fast and slow traders in the spot foreign exchange market. We find that the most notable impact of the tick size reduction is a substantial increase in the liquidity demand of high-frequency traders (HFTs) and not the decrease in their liquidity provision discussed by prior literature. We show that this change in behavior is linked to the higher frequency of price signals that arises with the smaller tick size and to the ability of fast traders to profit from it, often at the detriment of slower traders. Following the tick size decrease and the increase in liquidity demand by HFTs in the spot market, the role of the spot market in price discovery drops relative to that of the futures market. We discuss these findings in the context of the impact of HFTs on the information content of financial markets. This paper was accepted by Agostino Capponi, finance.

Assessment of Background Gamma Radiation Levels Across Major Markets in Southern Senatoria District of Cross River State, Nigeria

Human exposure to ionizing radiation from natural and artificial sources is unpreventable phenomenon on earth. Radiation profile and dose at for some markets in Cross River State, Nigeria have been ascertained using 451p ion chamber survey meter and the following indices of radiation absorb dose, annual effective dose equivalent, and excess life cancer risk, were calculated. the dose rate measures at the seven market are as follows; Biase 0.02\(\mu\)sv/h to 0.09\(\mu\)sv/h, Akamkpa 0.02\(\mu\)sv/h to 0.09\(\mu\)sv/h, Odukpani 0.02\(\mu\)sv/h to 0.09\(\mu\)sv/h marian market 0.06\(\mu\)sv/h to 0.19\(\mu\)sv/h, Calabar South, 0.05\(\mu\)sv/h to 0.30\(\mu\)sv/h, Akpabuyo 0.02\(\mu\)sv/h to 0.19\(\mu\)sv/h, Bakassi 0.02\(\mu\)sv/h to 0.16\(\mu\)sv/h. The mean value for dose is mean 0.047 \(\pm\) 0.018 for Biase, 0.043 \(\pm\) 0.018 for Akamkpa, 0.043 \(\pm\) 0.017 for Odukpani, 0.110 \(\pm\) 0.036 for Marian, 0.106 \(\pm\) 0.059 sv/h for Calabar South, 0.104 \(\pm\) 0.056 sv/h for Akpabuyo and 0.053 \(\pm\) 0.031 sv/h for Bakassi. Mean values of 0.073 \(\pm\) 0.026msvy-1, 0.067 \(\pm\) 0.029msv/y, 0.095 \(\pm\) 0.08msv/y, 0.158 \(\pm\) 0.072msv/y, 0.134 \(\pm\) 0.114msv/y, 0.159 \(\pm\) 0.084msv/y and 0.223 \(\pm\) 0.654 for AEDE were observed respectively for within the markets. Similarly, 0.259 \(\pm\) 0.092 x 10-3, 0.235 \(\pm\) 0.095 x 10-3, 0.338 \(\pm\) 0.265 x 10-3, 0.552 0.252 x 10-3, 0.470 \(\pm\) 0.397 x 10-3, 0.558 0.29 x 10-3, and 0.265 \(\pm\) 0.097 x 10-3 were recorded for ELCR, with the marketer the AEDE values are with the permissible limit as recommended by the international bodies, the ELCR values are also within permissible limit. The implication of the AEDE & ELCR values is that the markets sides is radiation safe for any radiological health burdens that might arise due to absorb dose from BIR, but the probability of are developing cancer over a life time exposure in market places is high. It’s recommended that periodic BIR monitory and evaluation and radioactive concentration of nuclides in soil and rocks of the area be carried out by local authority.

Fungal Mycobiome of Mature Strawberry Fruits (Fragaria x ananassa Variety 'Monterey') Suggests a Potential Market Site Contamination with Harmful Yeasts.

An amplicon metagenomic approach based on the ITS2 region of fungal rDNA was used to investigate the diversity of fungi associated with mature strawberries collected from a volcanic orchard and open-air market stands. Based on the Kruskal-Wallis test, no statistically significant differences were observed in both non-phylogenetic and phylogenetic alpha diversity indices. According to beta diversity analyses, significant differences in fungal communities were found between groups (orchard vs. market). Taxonomic assignment of amplicon sequence variables (ASVs) revealed 7 phyla and 31 classes. The prevalent fungal phyla were Basidiomycota (29.59-84.58%), Ascomycota (15.33-70.40%), and Fungi-phy-Insertae-sedis (0.45-2.89%). The most predominant classes among the groups were Saccharomycetes in the market group, and Microbotryomycetes and Tremellomycetes in the orchard group. Based on the analysis of microbiome composition (ANCOM), we found that the most differentially fungal genera were Hanseniaspora, Kurtzmaniella, and Phyllozyma. Endophytic yeasts Curvibasidium cygneicollum were prevalent in both groups, while Candida railenensis was detected in fruits originating only from the market. In addition, Rhodotorula graminis (relative abundance varying from 1.7% to 21.18%) and Papiliotrema flavescens (relative abundance varying from 1.58% to 16.55%) were detected in all samples regardless of origin, while Debaryomyces prosopidis was detected in samples from the market only, their relative abundance varying with the sample (from 0.80% to 19.23%). Their role in fruit quality and safety has not been yet documented. Moreover, several clinically related yeasts, such as Meyerozyma guilliermondii and Candida parapsilosis, were detected in samples only from the market. Understanding the variety and makeup of the mycobiome in ripe fruits during the transition from the orchard to the market is crucial for fruit safety after harvest.

Creating culturally-informed protocols for a stunting intervention using a situated values-based approach (WeValue InSitu): a double case study in Indonesia and Senegal

International development work involves external partners bringing expertise, resources, and management for local interventions in LMICs, but there is often a gap in understandings of relevant local shared values. There is a widespread need to better design interventions which accommodate relevant elements of local culture, as emphasised by recent discussions in global health research regarding neo-colonialism. One recent innovation is the concept of producing ‘cultural protocols’ to precede and guide community engagement or intervention design, but without suggestions for generating them. This study explores and demonstrates the potential of an approach taken from another field, named WeValue InSitu, to generate local culturally-informed protocols. WeValue InSitu engages stakeholder groups in meaning-making processes which ‘crystallize’ their envelope of local shared values, making them communicable to outsiders.Our research context is understanding and reducing child stunting, including developing interventions, carried out at the Senegal and Indonesia sites of the UKRI GCRF Action Against Stunting Hub. Each national research team involves eight health disciplines from micro-nutrition to epigenetics, and extensive collection of samples and questionnaires. Local culturally-informed protocols would be generally valuable to pre-inform engagement and intervention designs. Here we explore generating them by immediately following the group WeValue InSitu crystallization process with specialised focus group discussions exploring: what local life practices potentially have significant influence on the environments affecting child stunting, and which cultural elements do they highlight as relevant. The discussions will be framed by the shared values, and reveal linkages to them. In this study, stakeholder groups like fathers, mothers, teachers, market traders, administrators, farmers and health workers were recruited, totalling 83 participants across 20 groups. Themes found relevant for a culturally-informed protocol for locally-acceptable food interventions included: specific gender roles; social hierarchies; health service access challenges; traditional beliefs around malnutrition; and attitudes to accepting outside help. The concept of a grounded culturally-informed protocol, and the use of WeValue InSitu to generate it, has thus been demonstrated here. Future work to scope out the advantages and limitations compared to deductive culture studies, and to using other formative research methods would now be useful.
