Domestic dogs have been central to life in the North American Arctic for millennia. The ancestors of the Inuit were the first to introduce the widespread usage of dog sledge transportation technology to the Americas, but whether the Inuit adopted local Palaeo-Inuit dogs or introduced a new dog population to the region remains unknown. To test these hypotheses, we generated mitochondrial DNA and geometric morphometric data of skull and dental elements from a total of 922 North American Arctic dogs and wolves spanning over 4500 years. Our analyses revealed that dogs from Inuit sites dating from 2000 BP possess morphological and genetic signatures that distinguish them from earlier Palaeo-Inuit dogs, and identified a novel mitochondrial clade in eastern Siberia and Alaska. The genetic legacy of these Inuit dogs survives today in modern Arctic sledge dogs despite phenotypic differences between archaeological and modern Arctic dogs. Together, our data reveal that Inuit dogs derive from a secondary pre-contact migration of dogs distinct from Palaeo-Inuit dogs, and probably aided the Inuit expansion across the North American Arctic beginning around 1000 BP.

The sex/gender model used in biological archaeologies to investigate human remains and past lives is one that relies on the epistemological and ontological separation of sex and gender. Despite this separation the model ends up treating these concepts synonymously due to the taken-for-granted binary nature of sex which in a deterministic manner eventuates into an equally binary gender. This thesis develops a theoretical framework for an archaeological concept of gender that operates without the division, binarism and determinism implicit in the sex/gender model. Pursuing answers to the questions whether it is possible to approach both sex and gender in archaeology in a nonbinary way, and if so, what is an archaeologically feasible alternative, it seeks to devise a method to approach sex and gender in mortuary archaeology beyond the deterministic binary. This thesis is firmly theory-oriented and the writings of various authors within the discipline of archaeology, feminism and queer studies comprise the necessary material. The theories pertaining to the field of feminism are intersectionality and queer theory, which eschew normativity and essentialism and call for gender diversity. Respective to archaeology, the theories influencing this thesis derive from new materialisms to whom the rejection of divisions and dichotomies is characteristic. In this regard, of particular note are the writings of new materialist and feminist theorist Karen Barad. Applying her theories concerning the relational, entangled and mutually constitutive nature of matter and meaning to the topic of sex and gender is central in devising a nonbinary new materialist perspective to be used for the purpose of a more open and inclusive mortuary archaeology. This thesis reveals that the dualistic division between nature and culture has resulted in a separate conceptual development and different strategies of engagement concerning sex and gender. The reason why sex is seen as a biological fact and gender as a cultural meaning proves false when both are affected equally by nature and culture, with the body serving as a nexus-point in which these two forces converge. Applying Barad’s insight reveals that binary sex is not an inherent quality of the body, but one that is produced through a scientific biomedical apparatus. Sex and gender exist in a state of inseparability when undetermined, but when subjected to a determination process, they become mutually exclusive phenomena, thereby disrupting sex-to-gender determinism. In their separate state, both are constitutive of matter and meaning, which is why gender made determined through intersectionality can be used to study gendered understandings through the materiality of the body, exempt from binary views. Analysing a topical bioarchaeological publication concerning a female Viking warrior through the approach that does not depend on the sex binary reveals that a scientific biomedical apparatus is subject to criticism on multiple fronts. Though the case study should be credited with rejecting gender role stereotypes, it demonstrates determinism and binarism as well as homogeneity and universalism in terms of categories. Failing to imagine possibilities beyond a fixed binary also results in the exclusion of alternate ways of knowing and being. The open-ended approach proposed in this thesis not only seeks to grant these possibilities opportunities to exist, but counsels cognisance towards the exclusions apparatuses enact. Embracing speculation, it also holds ambiguity and vagueness to be meaningful qualities pertaining to gendered archaeology. Regarding the mortuary setting, binary sex determinations need not be abandoned, but they should be used alongside this nonbinary approach.

Increasingly code and algorithms are techniques also applied in textual scholarship, giving rise to new interactions between software engineers and textual scholars. This book argues that much of that process and its effects on textual scholarship are still poorly understood and go unchecked by otherwise normal processes of quality control in scholarship such as peer review. The text provides case studies in which some of these interactions become more apparent, as well as the academic challenges and problems that they introduce. The book demonstrates that the space between code creation and conventional scholarship is one that offers many affordances to textual scholarship that until now remain unexplored. The author argues that it is an intellectual obligation of programmers and textual scholars to examine the properties of digital text and how its existence changes and challenges textual scholarship.

O User Experience é possivelmente um dos principais aspetos para fidelizar um cliente numa solução cloud, as chamadas soluções SaaS (Software as a Service). O crescimento acentuado deste tipo de soluções aquece a rivalidade entre competidores e cada vez mais pretende-se oferecer as formas mais revolucionárias para premiar a qualidade de um serviço. Com o crescimento acentuado das técnicas na área do NLP (Natural Language Processing) a indústria começa a olhar para os chatbots como uma possível solução de automatizar, impulsionar e expandir as suas ofertas. A presente tese visa a apresentar uma implementação prática de um chatbot sobre um software com semelhanças de um CRM (Customer Relationship Management) existente intitulado por FOXAIO. Com o objetivo de desenvolver uma solução robusta e escalável tendo em atenção as condições elaboradas pela empresa em questão, um longo e detalhado estudo foi elaborado sobre as mais diversas técnicas de deep learning usadas no ramo de Processamento de Linguagem Natural (NLP). Atribuindo um particular ênfase às redes neurais recorrentes (RNN) e com a devida extensão Long Short Term Memory (LSTM) que juntas, formam e trabalham muito bem na resolução dos problemas de um sistema de inteligência artificial, como é o caso. Para a sua implementação sobre um software já existente, foi necessário o desenvolvimento de uma pequena interface conversacional com o objetivo de mais tarde a complementar sobre a interface do utilizador do mesmo. Para esse efeito, foi implementado um canal sobre o sistema conversacional de comunicação em protocolo de socket, criando uma classe para o efeito que mais tarde seria útil para gerar logs de análise. Durante a implementação do sistema conversacional foram feitas várias comparações sobre as variantes dos seus módulos desde o Dialog Management (DM) ao Intent Classifier onde várias arquiteturas foram expostas e comparadas com o intuito de corresponder à melhor solução possível para um chatbot de língua portuguesa em primeira instância, foi optado pela escolha de um Dialog Management híbrido face ao domínio e à existência de conversas contextuais contínuas onde, por exemplo, se torna bastante difícil de desenvolver sobre outros paradigmas. Quanto ao Intent Classifier, foi usada a técnica rasa tensorflow embedding, esta técnica (que treina palavras do princípio) usada obteve melhores resultados para o particular caso estudado na presente tese (CRM), do que por exemplo o uso um modelo de dados com palavras já treinadas. Finalmente, conseguimos apresentar hipoteticamente, possíveis melhorias do UX no uso de uma interface conversacional sobre uma interface tradicional, usando as várias ferramentas de análise disponíveis, onde por exemplo com o auxílio da framework HEART (criada pelo Google), conseguimos obter indicativos bastante satisfatórios por 34 pessoas que fizeram os primeiros testes no chatbot desenvolvido. Examinando o feedback desses mesmos utilizadores em ambiente de teste, conseguimos obter um resultado na escala de SUS (System Usability Scale) com um valor de 70, enquanto a interface tradicional arrecadou 58, notando então que as pessoas se sentiram mais capazes no uso do sistema conversacional. User Experience is one of the main aspects that maintain a customer loyal to cloud based solutions or SaaS (Software as a Service). With the rise of the natural language processing techniques, the industry is looking at automated chatbot solutions to boost and expand their services. This thesis presents a practical case study of the implementation of a chatbot solution to complement a CRM (Customer Relationship Management) software called FOXAIO, and then quantify, following the most appropriate guides and solutions available, the User Experience (UX) optimisation. In order to create a robust and scalable solution based on the constraints created by the company in the case, we reviewed the current deep learning techniques, tools and libraries available to help the development process. The most proven techniques in the field of Natural Language Processing (NLP) will be introduced. To achieve the goals of this solution without "reinventing the wheel", we present possible architectures to use at the top of some open source and available tools on the market, with a special relief in the framework RASA. Also we discussed some of possible techniques to create the intent classifier, where we detail the better performance in the top of the rasa tensorflow embedding pipeline for this particular case. The conversational system, also, required a channel to interact with the final user. To achieve that, we also implemented a basic chat interface created on the top of the socket protocol, which communicate with the conversation system. In any case, it would be possible to extend to the other channel’s available on the market, like messenger, slack, telegram. Finally, we detail with a few use cases, that’s hypothetically possible to improve the user experience of an existing software system (FOXAIO) using a conversational interface on the top of that. Also, we achieved some highlights about the preference to use a conversational interface because of his simplicity, defended by a better score in the SUS scale, 70 against 58 to the traditional UI, and good indicatives by the HEART framework.

Abstract copyright UK Data Service and data collection copyright owner.Background The Labour Force Survey (LFS) is a unique source of information using international definitions of employment and unemployment and economic inactivity, together with a wide range of related topics such as occupation, training, hours of work and personal characteristics of household members aged 16 years and over. It is used to inform social, economic and employment policy. The LFS was first conducted biennially from 1973-1983. Between 1984 and 1991 the survey was carried out annually and consisted of a quarterly survey conducted throughout the year and a 'boost' survey in the spring quarter (data were then collected seasonally). From 1992 quarterly data were made available, with a quarterly sample size approximately equivalent to that of the previous annual data. The survey then became known as the Quarterly Labour Force Survey (QLFS). From December 1994, data gathering for Northern Ireland moved to a full quarterly cycle to match the rest of the country, so the QLFS then covered the whole of the UK (though some additional annual Northern Ireland LFS datasets are also held at the UK Data Archive). Further information on the background to the QLFS may be found in the documentation. Longitudinal data The LFS retains each sample household for five consecutive quarters, with a fifth of the sample replaced each quarter. The main survey was designed to produce cross-sectional data, but the data on each individual have now been linked together to provide longitudinal information. The longitudinal data comprise two types of linked datasets, created using the weighting method to adjust for non-response bias. The two-quarter datasets link data from two consecutive waves, while the five-quarter datasets link across a whole year (for example January 2010 to March 2011 inclusive) and contain data from all five waves. A full series of longitudinal data has been produced, going back to winter 1992. Linking together records to create a longitudinal dimension can, for example, provide information on gross flows over time between different labour force categories (employed, unemployed and economically inactive). This will provide detail about people who have moved between the categories. Also, longitudinal information is useful in monitoring the effects of government policies and can be used to follow the subsequent activities and circumstances of people affected by specific policy initiatives, and to compare them with other groups in the population. There are however methodological problems which could distort the data resulting from this longitudinal linking. The ONS continues to research these issues and advises that the presentation of results should be carefully considered, and warnings should be included with outputs where necessary.New reweighting policyFollowing the new reweighting policy ONS has reviewed the latest population estimates made available during 2019 and have decided not to carry out a 2019 LFS and APS reweighting exercise. Therefore, the next reweighting exercise will take place in 2020. These will incorporate the 2019 Sub-National Population Projection data (published in May 2020) and 2019 Mid-Year Estimates (published in June 2020). It is expected that reweighted Labour Market aggregates and microdata will be published towards the end of 2020/early 2021. LFS Documentation The documentation available from the Archive to accompany LFS datasets largely consists of the latest version of each user guide volume alongside the appropriate questionnaire for the year concerned. However, volumes are updated periodically by ONS, so users are advised to check the latest documents on the ONS Labour Force Survey - User Guidance pages before commencing analysis. This is especially important for users of older QLFS studies, where information and guidance in the user guide documents may have changed over time. Additional data derived from the QLFS The Archive also holds further QLFS series: End User Licence (EUL) quarterly data; Secure Access datasets; household datasets; quarterly, annual and ad hoc module datasets compiled for Eurostat; and some additional annual Northern Ireland datasets. Variables DISEA and LNGLST Dataset A08 (Labour market status of disabled people) which ONS suspended due to an apparent discontinuity between April to June 2017 and July to September 2017 is now available. As a result of this apparent discontinuity and the inconclusive investigations at this stage, comparisons should be made with caution between April to June 2017 and subsequent time periods. However users should note that the estimates are not seasonally adjusted, so some of the change between quarters could be due to seasonality. Further recommendations on historical comparisons of the estimates will be given in November 2018 when ONS are due to publish estimates for July to September 2018. An article explaining the quality assurance investigations that have been conducted so far is available on the ONS Methodology webpage. For any queries about Dataset A08 please email Labour.Market@ons.gov.uk.Occupation data for 2021 and 2022 data files The ONS have identified an issue with the collection of some occupational data in 2021 and 2022 data files in a number of their surveys. While they estimate any impacts will be small overall, this will affect the accuracy of the breakdowns of some detailed (four-digit Standard Occupational Classification (SOC)) occupations, and data derived from them. None of ONS' headline statistics, other than those directly sourced from occupational data, are affected and you can continue to rely on their accuracy. For further information on this issue, please see: https://www.ons.gov.uk/news/statementsandletters/occupationaldatainonssurveys. Main Topics:The five-quarter longitudinal datasets include a subset of the most commonly used variables from the Quarterly Labour Force Survey (QLFS), covering the main areas of the survey.

We have before us the sixth issue of INSAM Journal of Contemporary Music, Art and Technology. This is the second issue in a row dedicated to the global crisis caused by the Covid-19 pandemic. After the overwhelming response from all over the world to the call for papers and provocative inspections that ensued, here we wanted to discuss the ways in which technology shapes and enables work in the areas of music, arts, humanities, and the education process, this time inviting our collaborators to discuss the shortcomings and struggles of the working processes in these fields. The main theme, “Music, Art and Humanities in the Time of Global Crisis”, expanded from the Main Theme section into the interviews as well.
