Infrastructures in Practice, Market Dynamics, and Historical Railways Tourism: The Appleton\u2019s Guide to the United States and Canada, 1879

This work historically analyses the infrastructural dynamics of the North American railway system and proposes a connection between the concepts of space, materiality and institutional dynamics which can be used for tourism management studies. The theory-building case study (in a grounded theory approach) is based on a BBC travel documentary on the Appleton\u2019s General Guide of 1879. Starting from the concepts of \u201cproduction of space\u201d and \u201csociospatial relations\u201d, the introduction of the specific material infrastructure dimension allows us: i) to pinpoint a theoretical framework over four levels (territory, place, scale, networks) in order to study the \u201cinstitutional dynamics of markets\u201d; (ii) and suggests a possible practice-based turn in destination marketing studies

Boundary Objects, \u201cTranslation\u201d and Institutional Work: \u201cConsuming History\u201d and \u201cA History of the World in 100 Objects\u201d

This paper analyzes the relationship between production and consumption in terms of relational materialism and performativity (Callon 1998; Latour 2005) in \u201ca posthumanist practice theory orientation\u201d (Nicolini 2012): (i) introducing the analogy of \u201cmaterial culture as text\u201d (Olsen 2013); (ii) and considering the practices of institutional work (Lawrence, Suddaby 2006) that connect \u201chuman and nonhuman actors\u201d (Carlile et al. 2013) with \u201cinstitutional dynamics in markets\u201d (Araujo et al. 2010; Dolbec, Fischer 2015). To investigate how things are transformed into (written) discourse and, in general, as the latter builds the relationship between things and texts (\u201ctextual approach to things\u201d: de Groot 2009; Olsen 2013), the work takes the form of a case study using an original project by the British Museum as revelatory incident (Belk 1988, 2006). The analogy with the \u201c(re)turn to things\u201d in the evolution of archaeological studies (Shanks, Tilley 1992; Olsen et al. 2012) allows you to reflect on a practice-based approach in marketing studies

On Identifying Signatures of Positive Selection in Human Populations: A Dissertation

As sequencing technology continues to produce better quality genomes at decreasing costs, there has been a recent surge in the variety of data that we are now able to analyze. This is particularly true with regards to our understanding of the human genome—where the last decade has seen data advances in primate epigenomics, ancient hominid genomics, and a proliferation of human polymorphism data from multiple populations. In order to utilize such data however, it has become critical to develop increasingly sophisticated tools spanning both bioinformatics and statistical inference. In population genetics particularly, new statistical approaches for analyzing population data are constantly being developed—unfortunately, often without proper model testing and evaluation of type-I and type-II error. Because the common Wright-Fisher assumptions underlying such models are generally violated in natural populations, this statistical testing is critical. Thus, my dissertation has two distinct but related themes: 1) evaluating methods of statistical inference in population genetics, and 2) utilizing these methods to analyze the evolutionary history of humans and our closest relatives. The resulting collection of work has not only provided important biological insights (including some of the first strong evidence of selection on human-specific epigenetic modifications (Shulha, Crisci, Reshetov, Tushir et al. 2012, PLoS Bio), and a characterization of human-specific genetic changes distinguishing modern humans from Neanderthals (Crisci et al. 2011, GBE)), but also important insights in to the performance of population genetic methodologies which will motivate the future development of improved approaches for statistical inference (Crisci et al, in review)

La popolazione dell’area metropolitana di Roma. Evoluzione demografica e previsioni al 2024

Il working paper presenta i risultati di un progetto di ricerca finanziato dalla Provincia di Roma e condotto dall’IRPPS-CNR e dal Dipartimento di Scienze Statistiche della Sapienza Università di Roma. Nel corso dell’ultimo decennio le immigrazioni straniere e i trasferimenti residenziali dal core urbano alle periferie hanno rappresentato gli eventi demografici più rilevanti nell’area metropolitana di Roma. Di queste tendenze si è tenuto conto nel definire le ipotesi alla base degli scenari evolutivi della popolazione dal 2009 al 2024. Le previsioni sono state condotte applicando due modelli previsivi multiregionali, di tipo stocastico e deterministico, sulle cinque sub-aree concentriche nelle quali è stata suddivisa l’area romana. Gli scenari concordano nel prevedere un incremento e un invecchiamento della popolazione dell’area, oltre ad un’ulteriore diminuzione del peso demografico della città di Roma

A Study on the Relationship between Teachers' Perception of Principal's Leadership Style and Teachers' Job Satisfaction at the Selected Bilingual School in Bangkok

The purpose of this study was to examine the relationship between teachers' perceptions of principal's leadership style and teachers' job satisfaction. The study also investigated the type of teachers’ perceptions of principal leadership style and level of teacher's job satisfaction at the selected bilingual school in Bangkok. The purposive sampling was consisted on 68 foreign teachers working at the selected bilingual school in Bangkok. The instrument used to collect data contained three sections that were adapted from Multifactor Leadership Questionnaire [MLQ] short form and Minnesota Satisfaction Questionnaire [MSQ]. In this study, means, standard deviation and Pearson correlation were the statistical techniques applied in data analysis. Based on the results, the findings indicated that from the teachers' perception of principal's leadership style the principal uses transformational leadership style and the level of teacher's job satisfaction is neutral. According to the correlation analysis, there is a significant relationship between teachers' perception of principal's leadership style and teacher’s job satisfaction at the selected bilingual school in Bangkok. A positive correlation was found between principal's leadership style and teachers' job satisfaction mean score; r = 0.686, Correlation is significant at the 0.01 level. The study recommended administrators of the selected bilingual school to use the study for further research. The study can provide the school with data for several purposes. Since no one has done any research on any one of the selected affiliated schools. It will help administrators be informed of existing problems happening and focus on their type of principal's leadership style. The study was able to help teachers to be able to express their feelings without standing out and it could help increase the level of teacher’s job satisfaction. The selected bilingual school should focus on certain components of leadership style in order to raise the level of teacher's job satisfaction that could be beneficial for the school, teachers and students
