De la fenomenología de la voluntad al primado de la persona en la acción. A. Pfänder y L. Polo
Tanto Pfänder como Polo han hecho unos estudios dignos
de mención en lo que a la ética se refiere. Queremos rescatar en este breve trabajo lo mejor de estos pensadores que desde perspectivas y métodos
muy dispares abordan temas y resuelven problemas de modos muy distintos
llevándonos, cada uno a su manera, al puerto seguro del ser personal. Dichos pensadores nos muestran que, tanto con el método de la fenomenología
realista como con el método poliano del abandono de la presencia, se puede entrever e incluso fundamentar el primado del ser personal en la acción
humana.Pfänder and Polo both have carried out studies that are
worth mentioning with regard to ethics. In this brief work we would like
to rescue what is best in these two thinkers who, from rather disparate
perspectives and methods, confront topics and resolve problems in rather distinct ways to carry us to the safe port of personal being, each in
his own manner. These two thinkers show us that it is possible to entertain
and even support the primacy of personal being in human action, using
the method of realistic phenomenology or the polianic abandonment
of presence
Novel classification method to predict the accuracy of UWB ranging estimates
Real time location systems (RTLSs) are becoming more relevant in a more data driven economy and society due to their wide range of application cases. When the location of an object needs to be tracked with high accuracy, ultra wideband (UWB) technology is usually the best option. Nevertheless, UWB ranging estimates are not completely immune to some sources of error such as non line of sight (NLOS) or multipath conditions. Thus, this paper proposes a real-time classification model based on machine learning (ML) to predict if received ranging estimates are in line of sight (LOS) or NLOS conditions and discard those in NLOS. However, it is also shown that classifying measurements as LOS or NLOS does not guarantee detecting inaccurate ranging estimates, since LOS measurements can also yield large errors. As an example, the ranging root mean square error (RMSE) of the data labelled as LOS in a UWB based localization system database in the literature is of 0.714 m, significantly higher than the theoretical accuracy of a UWB system. Thus, a novel ML-based classification model is proposed to predict the magnitude of the ranging error. After applying the proposed classification model in the same data, the ranging RMSE of those ranging samples classified as most accurate is of only 0.183 m, significantly lower than the best RMSE we can obtain on the classical LOS/NLOS classification approach
Towards Transparent Decision-Making Processes Within Museums: Case Study of Museu Nacional d’Art de Catalunya (MNAC)
Understanding that good decision-making is paramount for the success of an organization and recognizing that strategic decision-making inside museums is a topic that has been over-passed by researchers, this paper intends to contribute to the relevance of the subject through the implementation of an innovative tool. Decision-making in museums is normally focused on the intuition, subjectivity, and experience of the curator, who brings all his knowledge to the exhibition programming. However, museums’ management and environment are constantly changing, thus the application of this tool would aim to make decisions in a more democratic, transparent, inclusive, and accurate manner. Besides, it will be easier to understand how distinct subjects can work together, demonstrating successful results to improve the decision-making process when programming and measuring temporary exhibition seasons in museums. This paper describes the design and implementation of the Multi-Attribute Utility Theory (MAUT) for the Museu Nacional d’Art de Catalunya (MNAC). It also analyzes and evaluates the decision-making process when scheduling exhibitions for a season
Persistence of human capital development in OECD countries over 150 years: evidence from linear and nonlinear fractional integration methods
The goal of this study is to examine the persistence of human capital development in 21 member
countries of the Organization for Economic Cooperation and Development for the period
1870–2019. Gross enrollment rates for secondary and tertiary education are both used as proxies
for human capital development. Employing linear and nonlinear fractional integration approaches, our results suggest high degrees of persistence in the series under examination.
However, lower orders of integration are observed in the data for tertiary education than for
secondary education. Thus, no evidence of reversion to the mean is found in secondary education,
and Australia and New Zealand have the highest coefficients for the time trends and the highest
dependence. However, mean reversion in tertiary education is found in France, the US, and, in
particular, Austria. Finally, evidence of nonlinearity is observed in about eight countries, though
without altering the persistence in the series. The implications of the empirical results are also
presented
Exploring the impact of loyalty program on consumption in the Spanish beauty industry
This research aims to explore the impact of loyalty programs on consumer behavior within the
Spanish beauty industry, focusing on how different types of loyalty programs and their specific
benefits influence consumer spending. Utilizing a mixed-method approach combining qualitative
and quantitative data, this study provides a comprehensive analysis of consumer preferences and
behaviors associated with loyalty programs. The study begins with a detailed literature review,
examining existing research on loyalty programs, their structures, and their perceived benefits. The
literature highlights the significance of loyalty programs in fostering repeat purchases and enhancing
customer retention. Various types of loyalty programs, including point systems, tier systems, and
non-monetary programs, are discussed, along with their respective utilitarian, hedonic, and symbolic
benefits. The research methodology includes a survey conducted with 291 respondents, of which
187 were valid and used for analysis. Descriptive statistics and multiple regression analyses are
employed to interpret the data and identify significant trends and relationships.
Key findings indicate that while consumers value point and tier system loyalty programs, these do
not necessarily drive higher value in consumption. Instead, non-monetary loyalty programs, which
focus on exclusive experiences and personalized rewards, are more effective in increasing consumer
spending. Utilitarian benefits, such as saving money through loyalty programs, are highly valued
but tend to decrease the overall monetary value spent, as indicated by a negative coefficient in the
model. Hedonic benefits, including discovering new products and redeeming points, show a positive
correlation with consumer spending. The study also reveals that symbolic benefits, while appreciated
by consumers, do not significantly drive sales or consumption. The high sentiment of program
loyalty among respondents, particularly in the beauty sector, is a critical factor influencing
consumption. These insights underscore the importance of designing loyalty programs that blend
monetary and non-monetary rewards to cater to diverse consumer preferences.
Practical implications for companies in the beauty industry include the need to develop well-rounded
loyalty programs that offer a mix of point-based rewards, tiered benefits, and personalized
experiences. Companies should also consider targeting higher-income consumers with premium
offerings and exclusive events to enhance revenue and build a loyal customer base. Strategies aimed
at increasing purchase frequency, such as regular promotions and reminders about loyalty program
benefits, can also drive overall spending and foster long-term consumer habits.
This study contributes to the existing literature by providing a nuanced understanding of how
different loyalty program structures and benefits impact consumer behavior in the Spanish beauty industry. Future research should explore the long-term effects of loyalty programs and consider
cultural differences in consumer preferences and behaviors. This research offers valuable insights
for businesses looking to optimize their loyalty programs to enhance customer satisfaction and drive
sustainable growth
Clinical management of plant food allergy in patients sensitized to lipid transfer proteins is heterogeneous: identifying the gaps
Background and objective: Patients sensitized to lipid transfer protein (LTP)
present a wide clinical variability. The lack of practical diagnostic and therapeutic
guidelines complicate their management. The aim of the study was to describe
the clinical approach of Spanish allergists to this pathology using a survey
designed by PICO method and subsequent Delphi approach validation.
Methods: Designed survey was answered by 224 allergists (75% women; 57.1%
with >20 years of professional experience). Homogeneity regarding clinical
practice on the main points of LTP allergy diagnosis was observed, except for
patients with suspected NSAID hypersensitivity (44.6% frequently include LTP
skin testing). Oral food challenges were not frequently performed (63.6%
occasionally to never), and they were generally (75.5%) used to confirm
tolerance. It was common to recommend fruit skins avoidance (77.2%) and
maintaining consumption of foods to which patients are sensitised but tolerant
(99.1%).
Results: There was heterogeneity on other dietary indications, modifications due
to co-factors, or traces avoidance. Peach sublingual immunotherapy (SLIT) was
considered very/quite effective by 55.9% of allergists. The majority (79.5%)
consider SLIT indicated in <25% of LTP allergic patients, based on severity
(95.2%), frequency of reactions (99.4%), allergy to multiple food families (97.4%),
and the quality of life/nutrition impairment (91.5%). There was different practice
on SLIT prescription based on co-factor involvement.
Conclusion: These data suggest that there is a need to increase evidence to
reduce the clinical practice heterogeneity in the management of LTP allergy
Methylene blue for surgical excision of digital myxoid cysts after sonography: Addressing the challenge of identifying the drainage tract
Digital mucous cysts are benign pseudocysts that frequently present as solitary lesions on the proximal nail folds, arising from the joint capsule and typically containing clear fluid. Although several therapeutic options exist for digital mucous cysts, the recurrence rate is high, and surgical excision remains the most effective choice1. Nevertheless, the use of ultrasound could assist in the identification of the drainage tract of the cyst within the join
