Designed for experienced librarians, librarians new to the profession, and library school students, OnlineTeaching and Learning: A Practical Guide for Librarians provides a comprehensive framework that encompasses all aspects of planning, designing, creating, implementing, and assessing online learning for all types of libraries, including public, academic, special, and K-12. It also provides a valuable guide for teachers, administrators, and other educators.

Online Teaching and Learning: A Practical Guide for Librarians features three main sections:

Section I: Theory into Practice forms the basis in theory of learning that ultimately influences practice. It includes definition, importance in today’s society, benefits and challenges, and categories and types of online learning with examples to illustrate each.

Section II: Creating Online Instruction explores how to create an online course--describing components and stepping through the process using a model on the topic of information literacy. Design and instructional tips for creating other types of online instruction are also given.

Section III: Practical Applications provides examples of different types of online instruction and materials in all types of libraries. Then, step-by-step detail explains how librarians can create this type of instruction and/or learning materials on their own. Included are worksheets, handouts, and exercises.

Online Teaching and Learning: A Practical Guide for Librarians puts it all together to provide what the library must consider as it prepares for this new challenge and opportunity. It provides a comprehensive guide instructing online programs how to employ library services as part of their program. It is also designed to instruct librarians to incorporate the skills necessary to build a virtual library environment and teach the skills required to meet the needs of online learners. As the educational landscape changes with blended and online learning taking center stage, new and established librarians need a guide to inform them of skills they will need and show them how to create the resources for their new online audience.
Calvin Peete
Authors: Hobson Gordon
Published: September 2024

The first-ever biography of an overlooked PGA star and one of the best Black golfers in history.

His story is unprecedented in the world of golf. Born to a family of migrant laborers, Calvin Peete dropped out of school in the eighth grade, went to work picking crops, first swung a golf club at the age of 23—and rose to the top of the PGA.

In Calvin Peete: Golf's Forgotten Star, Gordon Hobson tells for the first time Peete’s incredible story. Hobson recounts how, when Peete joined the lily-white PGA tour in 1976, he stood out from the competition in more ways than one. Peete wasn’t raised in country clubs and didn’t learn the game at prestigious golf universities. He sported a huge Fu Manchu, cowboy boots, and had diamonds embedded in his teeth. Peete had a permanently bent left elbow and practiced endless hours in a public park to develop one of the most accurate swings in the history of golf. He endured years of futility and despair, but, eventually, he emerged as the best player on the Tour from 1982-86.

Calvin Peete’s story is inspiring, but it also reveals the struggles many Black golfers endured even after the Caucasian-only clause was removed from the PGA’s bylaws. He may have won twelve championships, played on the US Ryder Cup team twice, and won the prestigious Vardon Award, but the road to success wasn’t easy. Calvin Peete: Golf’s Forgotten Star shows how, even without the advantages some people are born into, one can find success through hard work, determination, and fortitude.
Donald J. Trump and the Politics of Mass Society
Authors: Melone Albert P.
Published: September 2024

In Donald J. Trump and the Politics of Mass Society, Albert P. Melone studies Trump’s behavioral patterns in the fourth year of his presidential term and the three tumultuous years leading to the 2024 presidential election. Melone analyzes the leading explanatory paradigm of American government and politics by utilizing the democratic and aristocratic criticisms of mass society theory to better describe and explain the behavior of Donald Trump and his followers. The initial chapters outline the theoretical framework, the mass movement characteristics, and its membership’s cult-like behavior. Two significant events of the last year of Trump’s administration— the pandemic and the politics surrounding the Black Lives Matter demonstrations— illustrate Trump’s leadership style and the behavioral patterns of the MAGA mass movement. The 2020 election and the attempt to reverse its outcome is a central topic throughout the text, including a discussion of Trump’s second impeachment, the efforts of the House Select Committee on January 6th, voter reactions in the 2022 midterm elections, and the various political and legal attempts to make Trump accountable for his role in the so-called insurrection at the nation’s Capitol. In the final chapter, Melone critically analyzes alternative prescriptions to right the ship of state with a steely eye focused on the realities and possibilities to salvage the democratic republic from an autocratic future.
Association of Gender and Personal Choices with Salaries of New Emergency Medicine Graduates
Authors: Gallahue Fiona E. , Ling Louis J. , Quigley Leo , Evans Dian Dowling , Salsberg Edward , Suter Robert E. , Marco Catherine A.
Published: September 2024

Objective: The medical literature has demonstrated disparities and variability in physician salaries and, speciﬁcally, emergency physician (EP) salaries. We sought to investigate individual physician characteristics, including sex and educational background, together with individual preferences of graduating EPs, and their association with the salary of their ﬁrst job. Methods: The American College of Emergency Physicians and the George Washington University Mullan Institute surveyed 2019 graduating EPs. The survey included respondents’ demographic and educational background, post-training job characteristics and location, hospital characteristics, importance of different personal priorities, and starting salaries. We performed a multivariable regression analysis to determine how salaries were associated with job types and individuals’ characteristics. Results: We sent surveys to 2,192 graduating residents in 2019. Of these, 487 (22.2%) responded, and 270 (55.4%) accepted ﬁrst-time clinical jobs and included salary data (12.3% of all surveys sent). Male sex, osteopathic training, and full-time work were signiﬁcantly associated with higher salary. Men and women prioritized different factors in their job search. Women were more likely to consider such factors as parental leave policy, proximity to family, desired practice setting, type of hospital, and desired location as important. Salary/compensation was considered very important by 51.8% of men and 29.6%of women. Men’s median salary was $30,000 more than women’s (p= 0.01, 95% CI +$6,929 ± $53,071), a signiﬁcant pay differential. Conclusion: Salaries of graduating emergency medicine residents are associated with the resident’s sex and degree type: doctor of osteopathic medicine or doctor of allopathic medicine. Multiple factors may contribute to men having higher salaries than women, and some of this difference reﬂects different priorities in their job search. Women were more likely to consider job conditions and setting to be more important, while men considered salary and compensation more important.

Authors: Piran Hamlabadi Milad , Jafarnezhadgero Amir Ali , Anvari Maryam , Hossienpour Kimia
Published: September 2024

Background: The type of footwear worn by military personnel and others could increase the risk of overuse injuries. Objectives: This study aimed to compare muscular activity during running with new and used military boots and running footwear in healthy individuals. Methods: Thirty healthy males were given a new pair of running footwear (n = 15) and thermoplastic polyurethane military boots (n = 15). Participants in each group were asked to wear these shoes for 6 months. Electromyographic activity of the dominant limb muscles was recorded during running at a speed of 3.3 m/s before and after 6 months. Results: The results indicated significant differences in muscle activity based on the type of footwear worn during various phases of running. Specifically, muscles such as the tibialis anterior, vastus lateralis, rectus femoris, biceps femoris, and semitendinosus showed varied activity during phases such as loading, mid-stance, and push-off. Additionally, there were significant effects of time on certain muscles, including the tibialis anterior and gastrocnemius medialis during the push-off phase. Interactions between footwear type and time were observed for the semitendinosus and gluteus medius during the loading phase, and the gastrocnemius medialis during the push-off phase. Conclusions: The results of this study indicate a decrease in muscle activity for most lower limb muscles in the military boots group compared to the running footwear group during the stance phase of running. The magnitude of gastrocnemius medialis activity increased in the military boots group (but not in the running footwear group) from pre-test to post-test during the push-off phase.

Context.—

Gastrointestinal manifestations of Kaposi sarcoma are rare but may cause morbidity. Lower gastrointestinal involvement is particularly rare and lesions may resemble conventional bowel polyps.

Objective.—

To study 15 patients who presented with lower gastrointestinal tract Kaposi sarcoma with polypoid architecture.

Design.—

The surgical pathology files of the departments of pathology at multiple institutions were searched for cases of Kaposi sarcoma forming polyps in the lower gastrointestinal tract (jejunum, colon, rectum); 15 cases with such features were identified. Clinicopathologic information was extracted from the medical record and documented by reviewing individual hematoxylin-eosin stained slides.

Results.—

The patients were 13 men and 2 women aged 26–80 years (median = 44 years). Gastrointestinal tract involvement was multifocal in 11 cases and unifocal in 4. The tumors involved the rectum, recto-sigmoid junction, cecum, ascending colon, transverse colon, and descending colon and presented as polypoid lesions measuring 0.2–2.1 cm. Six patients had upper gastrointestinal tract involvement in addition to lower gastrointestinal lesions. Histologically the tumors were characterized in 6 cases by a dense spindle cell proliferation in the lamina propria; however, the remaining cases showed only a subtle fascicular spindle cell proliferation in the lamina propria that did not form an expansile mass.

Conclusions.—

Biopsies of gastrointestinal polyps showing absence of the common features of hyperplastic or adenomatous polyps, particularly in immunocompromised patients, should be carefully examined for the presence of a stromal spindle cell proliferation. Use of immunohistochemical stains, particularly human herpesvirus-8, can help in establishing the correct diagnosis.
Challenges for expanding inventories of climate possibilities through indigenous and local knowledges in rural Zambia
Authors: Manda Simon , Matenga Chrispin , Mdee Anna , Smith Ruth , Nkiaka Elias
Published: September 2024

This article explores the integration (or marginality) of indigenous and local knowledge (IKL) in donor-driven community climate adaptation (CDCA) projects and the extent to which this helps expand inventories of adaptation possibilities for host communities and strengthen climate adaptation resilience in Zambia. Through multi-level qualitative research design, this study reveals that, even where climate interventions are intentional about being inclusive of community knowledge, they are likely to promote policy-centric knowledges and interventions that invisibilises ILK. Empirical evidence shows the application of CDCA expresses top-down assumptions of livelihood resilience and embeds uncritical views of what community is, including what might be socially and culturally appropriate forms of adaptation. CDCA implementation strategy is exclusionary and misaligned with ILK, affecting possibilities of knowledge intersection. This article elucidates how climate adaptation that marginalises ILK fails to expand inventories of climate adaptation possibilities for communities supposed to be adapting and proposes how this gap could be bridged.

Validación de Escalas de Eventos Adversos en Neurocirugía Infantil
Authors: Saravia Toledo Alejandro , Jaikin Mario Sergio
Published: September 2024

Introducción: Todos los neurocirujanos convivimos con eventos adversos [EA] durante nuestra práctica. Estas situaciones son registradas de manera poco sistematizada, en ocasiones naturalizando su ocurrencia, en otras atribuyendo el evento a factores externos al equipo neuroquirúrgico y también como señalamiento “culposo”. No existen escalas de EA propuestas en Neurocirugía infantil, y las pocas publicaciones hacen referencia a EA en cirugía de craneosinostosis exclusivamente.Material y métodos: Estudio retrospectivo y descriptivo sobre 290 pacientes operados entre 01/05/20 al 01/05/21 en nuestro servicio. Se evaluaron la aparición de EA y se los clasificó utilizando las escalas propuestas por Landriel, modificado de Dindo-Clavien y la de Houkin.Resultados: De los 290 pacientes, se evidenciaron EA en el 24,8 % (n = 72). 45 % en cirugía  oncológica (n = 33), 35 % en hidrocefalia (n = 25), 7 % en  malformaciones congénitas (n = 5), 7 % en lesiones vasculares (n = 5) y 6 % en otros procedimientos (n = 4). Se presentaron EA en el 67 % (n = 48) de cirugías programadas y en un 33 % (n = 24) cirugías de urgencia. Utilizando la escala de Houkin se manifestó predominio en el grado 2 con un 59 % (n = 43) y grado 4 con un 18 % (n = 13) de las complicaciones totales. En la escala de Landriel predominaron los EA grado 2B con un 44 % (n = 32) y 1B con 19 % (n = 14). Prevalecieron los EA de tipo neurológico, representando el 76 % (n= 55) del total. Dentro de este grupo, las infecciones (19 %), las disfunciones mecánicas (14 %), el deterioro neurológico (13 %) y la aparición de foco (8 %) fueron los más frecuentes. Mortalidad fue 2,7 % (n = 2).Conclusión: La incorporación de las clasificaciones de complicaciones propuestas por Landriel y Houkin, aplicando los criterios para los pacientes pediátricos, son válidas y pueden utilizarse en Neurocirugía Pediátrica.
¿Cómo transformar un elipsoide en un esferoide? Técnica quirúrgica para la corrección de la sinostosis sagital basada en un modelo geométrico
Authors: Morsucci E. , Houssay A. , Beninca J. , Ferraro Florencia , Ibáñez M.
Published: September 2024

INTRODUCCION:  La sinostosis sagital es la craneoestenosis más frecuente. Aún existe debate sobre cuál es el método quirúrgico más adecuado para su tratamiento. En este trabajo se presenta una técnica quirúrgica basada en un modelo geométrico que responde a la pregunta ¿Cómo transformar un cuerpo elipsoide en uno esferoide?MATERIAL Y MÉTODOS: ​ Se describe una técnica quirúrgica que permite modelar el cráneo de un lactante de conformación dolicocéfala. Se desarrolló un modelo geométrico que muestra, paso a paso, cómo se modifica una figura elipsoide, mejorando su relación ancho / largo.  Posteriormente este modelo en “el plano” se trasladó a una maqueta, pudiendo verificar el cambio de forma. Presentamos 8 casos de pacientes operados, demostrando que el modelo teórico se correlaciona con el modelo “in vivo”.RESULTADOS: Se operaron 8 pacientes portadores de Escafocefalia, 6 varones y 2 niñas. Las edades estuvieron en el rango de 2 a 7 meses. En todos se verificó una mejora del índice cefálico (IC), medido en el postoperatorio inmediato. El IC promedio previo a la cirugía fue de 0,67 DS=0,021 y, para la misma población en el postoperatorio, fue   0,77 DS=0,035. El test t de Student para muestra pareadas fue de 7,84 lo que da una P de hipótesis nula <0,01%. El aumento del índice está correlacionado con la edad al momento de la cirugía, (R = 0,76) con un coeficiente negativo (b = -0,02), que indica que los mejores resultados se observan en los pacientes de menor edad.DISCUSIÓN: Desde la primera cirugía para la corrección de la sinostosis sagital, realizada en 1890, se han​ propuesto distintas técnicas. Las menos invasivas por vía endoscópica deben ser suplementadas con el uso de ortesis craneal (casco) durante varios meses. En el otro extremo tenemos cirugías más invasivas como la reconstrucción total de la bóveda craneal, que estaría indicada en pacientes mayores. La técnica quirúrgica aquí desarrollada ofrece una alternativa intermedia, que no requiere ortesis postoperatoria, dispositivos expansores ni material protésico.CONCLUSION: ​ La presente técnica quirúrgica, basada en un modelo geométrico, ofrece inmediata corrección del índice cefálico, demostrado por medidas cuantitativas, análisis estadístico, imágenes y fotografías. Debido a los pocos casos operados hasta el momento, queda por determinar hasta qué edad es eficiente esta técnica.

Resultados: anatomía de la región cervical y femoral, constituida por grupos musculares, fascias, glándulas y paquetes vasculonerviosos. Se realizó un abordaje cervical con la anastomosis termino-terminal de la Arteria Carótida Común. En el otro espécimen se efectuó un acceso femoral izquierdo y anastomosis termino-lateral entre la Vena Femoral y la Vena Epigástrica Caudal Superficial. Se comprobó la adecuada permeabilidad vascular mediante ecodoppler.
Conclusión: El uso de modelos vivos para el entrenamiento microvascular son sumamente necesarios y efectivos para adquirir destrezas microquirúrgicas en nuestra formación como neurocirujanos. Siendo un modelo clásico de simulación y entrenamiento, es imprescindible adquirir el conocimiento anatómico de los espécimen, como así también el ejercicio de las técnicas de anastomosis vasculares.
A comprehensive exploration of complete cross-validation for circular data
Authors: Hasilová Kamila , Horová Ivana , Vališ David , Zámecník Stanislav
Published: September 2024

Kernel density estimation of circular data has recently received considerable attention for its ability to model and analyse distributions on unit circles and other periodic domains. Our aim is to contribute to the literature on data-driven bandwidth selectors in circular kernel density estimation. We propose a novel circular-specific method that is based on a crossvalidation procedure with a von Mises density used as a kernel function. Using simulated data as well as real-world circular datasets, we evaluate and validate the proposed method and compare it with the existing methods.
Comparing logistic regression and neural networks for predicting skewed credit score: a LIME-based explainability approach
Authors: Wangui Wanjohi Jane , Nyunga Mpinda Berthine , Olawale Awe Olushina
Published: September 2024

Over the past years, machine learning emerged as a powerful tool for credit scoring, producing high-quality results compared to traditional statistical methods. However, literature shows that statistical methods are still being used because they still perform and can be interpretable compared to neural network models, considered to be black boxes. This study compares the predictive power of logistic regression and multilayer perceptron algorithms on two credit-risk datasets by applying the Local Interpretable Model-Agnostic Explanations (LIME) explainability technique. Our results show that multilayer perceptron outperforms logistic regression in terms of balanced accuracy, Matthews Correlation Coefficient, and F1 score. Based on our findings from LIME, building models on imbalanced datasets results in biased predictions towards the majority class. Model developers in the field of finance could consider explanation methods such as LIME to extend the use of deep learning models to help them make well-informed decisions.
Forecasts of the mortality risk of COVID-19 using the Markov-switching autoregressive model: a case study of Nigeria (2020–2022)
Authors: Oluwasayo Ayodeji Idowu
Published: September 2024

The global pandemic due to SARS-Cov-2 ravaged the world and killed more than 6 million people globally within two years. Studies predicting future occurrences are essential to effectively combat the virus. This study modeled daily fatality rate in Nigeria from March 23, 2020 to March 19, 2022 and forecast future occurrences using Markov switching model (MSM). MSM estimates segmented fatality rates into three states of low-, medium- and high-risks. Further, estimates revealed that as at 19th March, 2022, Nigeria remained at the low-risk regime in which 1 (95%CI: 0, 1) person, on the average, died of coronavirus daily; however, the most probable scenario in the nearest future was the medium-risk state in which an average of 4 (95%CI: 2, 5) persons would die daily with 48.7% probability. The study concluded that Nigerian COVID mortality risks followed a switching pattern which fluctuated within low-, medium- and high-risks; however, the medium-risk state was most likely in the future. Our results indicated that the quarantine measures adopted by the governments yielded positive results. It also underscored the need for governments and individuals to intensify efforts to ensure that the country remained at the low-risk zone till the virus would be eventually eradicated.
The use of the Bennet indicators and their transitive versions for scanner data analysis
Authors: Białek Jacek
Published: September 2024

Although modern price index theory is based on comparisons of ratios of prices, quantities and expenditures, we may be more interested in the magnitude of differences in these characteristics in many business applications. The benefit of using these differences is that there is no problem associated with the occurrence of zero prices and quantities, a problem that arises when we work with ratios. In practice, we most often care about decomposing value difference into indicators of contributions from price and quantity differences. The best-known price and quantity indicators are the Bennet indicators, which are not transitive. Although there have been papers in the literature that propose a transitive version of the Bennet indicators, they deal with comparisons across firms in cross-section or panel contexts. This paper revises the price and quantity Bennet indicators and their multilateral versions for the analysis of scanner data. Specifically, i nstead o f c onsidering c omparisons across firms, c ountries or r egions, the t ransitive versions of t he Bennet i ndicators a re a dapted to work on scanner data sets observed over a fixed time w indow. Since the scanner data sets have a high turnover of products, which can make it difficult to interpret the difference in sales values over the compared time periods, the paper also considers a matched sample approach. One of the objectives of the study is to compare bilateral and multilateral Bennet indicator results across all available products or strictly matched products over time. It also examines the impact of data filters used and the level of data aggregation on the price and quantity Bennet indicators. According to the best author’s knowledge, this study is a pioneer in the field of implementing the multilateral Bennet indicators in scanner data analysis.
Language independent algorithm for clustering text documents with respect to their sentiment
Authors: Korzeniewski Jerzy , Idczak Adam
Published: September 2024

Determining the sentiment of a written text is an important task in text research. This task can be performed either in the supervised or unsupervised version. In this paper, we propose a novel unsupervised algorithm for documents written in any language using documents written in Polish as an example. The clustering of Polish language texts with respect to their sentiment is poorly developed in the literature on the subject. The novelty of the proposed algorithm involves the abandonment of stoplists and lemmatisation. Instead, we propose translating all documents into English and performing a two-stage document grouping. In the first step of the algorithm, selected documents are assigned to a class of positive or negative documents based on a set of lexical and grammatical rules as well as a set of key-terms. Key-terms do not have to be entered by the user, the algorithm finds them. In the second step, the remaining documents are attached to one of the classes according to the rules based on the vocabulary found in the documents grouped in the first step. The algorithm was tested on three corpora of documents and achieved very good results.
A finite state Markovian queue to let in impatient customers only during K-vacations
Authors: Sivasamy Ramasamy
Published: September 2024

We investigate a matrix analysis study for a single-server Markovian queue with finite capacity, i.e. an M/M/1/N queue, where the single server can go for a maximum, i.e. a K number of consecutive vacation periods. During these vacation periods of the server, every customer becomes impatient and leaves the queues. If the server detects that the system is idle during service startup, the server rests. If the vacation server finds a customer after the vacation ends, the server immediately returns to serve the customer. Otherwise, the server takes consecutive vacations until the server takes a maximum number of vacation periods, e.g. K, after which the server is idle and waits to serve the next arrival. During vacation, customers often lose patience and opt for scheduled deadlines independently. If the customer’s service is not terminated before the customer’s timer expires, the customer is removed from the queue and will not return. Matrix analysis provides a computational form for a balanced queue length distribution and several other performance metrics. We design a ‘no-loss; no-profit cost model’ to determine the appropriate value for the maximum value of K consecutive vacation periods and provide a solution with a numerical illustration.

The article deals with the problems of creating networks of routes for the successful differentiation of the tourist centers of Altai by functional elements. Based on the results of the analysis of existing attractors for tourism and their geography, the features of creating networks of tourist routes in the Altai region are revealed. One of the results of the work was the consideration of the scalability phenomenon when creating an optimal network of routes for the region within the Altai Republic, as well as the southern part of the Altai Territory in the area of its foothill and mountainous parts. The differentiation of service areas of tourist centers in the study was carried out along the administrative boundaries of the regions, in some cases - along mountain ranges separated by wide river valleys and watersheds. The paper proposes a model for constructing a destination complex: a tourist center - an administrative district subordinate to it - a complex of attractors. A “tourist center” is a locality where catering and accommodation organizations, tourist administrations, tourist information or visitor centers, as well as control and rescue services are located. „Subordinate administrative regions“ are administrative regions that include mountain ranges, plateaus, hills or plains within their borders, on which there is a dense network of various tourist destinations that are integral parts of mountain, water, walking and horse routes. On the territory of these regions there are „attractors“ - systems of geographical (lakes, rivers, remnants, peaks, passes, water structures, waterfalls, rapids) and cultural and historical (archaeological and ethnographic) objects.
Statistics in Personalized Medicine: Challenges and Innovations
Authors:   Faculty of Medicine Kampala International University Uganda, Umulisa Kanyana J.
Published: September 2024

Personalized medicine represents a paradigm shift in healthcare, aiming to tailor medical treatments to individual patients based on their unique genetic profiles, lifestyle factors, and environmental influences. At the forefront of this transformation lies statistics, which plays a pivotal role in integrating diverse data sources, identifying biomarkers, and developing predictive models that guide personalized treatment decisions. However, statistics in personalized medicine face challenges such as data integration complexities, small sample sizes, and ethical considerations. Despite these challenges, innovative statistical approaches including machine learning, Bayesian inference, and multi-omics integration are driving advancements. The future of statistics in personalized medicine lies in integrating multi-omics data, adopting artificial intelligence for predictive modeling, enhancing quantitative pharmacology, leveraging real-world evidence, and addressing ethical and regulatory frameworks. By advancing these fronts, statistics holds the promise to optimize treatment outcomes, improve patient care, and redefine the landscape of healthcare delivery in the 21st century.

With the rise in mobile device use, m-commerce is becoming the preferred method for electronic transactions. Consequently, models explaining consumer behavior in technology adoption are evolving. Among these, the UTAUT model stands out as one of the most frequently used. The aim of this paper is to determine whether variables such as performance expectancy, effort expectancy, social influence, and trust influence consumers' intention to use mobile commerce services. Additionally, the paper examines whether personal innovativeness significantly moderates the relationship between these variables and the intention to use mobile commerce. The study employs descriptive statistical analysis, reliability analysis, correlation analysis, multiple regression analysis, and moderation regression analysis. The results show that performance expectancy, effort expectancy, social influence, and trust are drivers of the intention to use mobile commerce. Furthermore, the findings indicate that personal innovativeness significantly moderates the relationship between trust and the intention to use mobile commerce in the future. The research results may be useful for m-commerce service providers in terms of improving system security, promoting the utility value of these services. The originality of this paper lies in testing the moderating role of personal innovativeness in the relationship between the mentioned variables and the intention to use m-commerce.

Este artículo explora la aplicación de la teoría del Juego de Doble Nivel de Robert Putnam a la crisis diplomática entre México y Cuba en 2004, arrojando luz sobre las complejidades de la toma de decisiones en política exterior. El marco teórico de Putnam, que incorpora el concepto de winsets, resulta fundamental para descifrar las interacciones matizadas entre factores internacionales y domésticos que influyeron en las acciones consideradas por el presidente Vicente Fox y sus asesores. El artículo destaca la aplicabilidad de los tableros de negociación con Estados Unidos y Cuba, así como la polarización interna entre grupos conservadores y nacionalistas. Investigadores y académicos interesados en los asuntos exteriores de México encontrarán este marco teórico valioso para análisis comprehensivos de los procesos de toma de decisiones diplomáticas.
