The overall purpose of the study is to investigate narcissistic leadership in the Swedish Armed Forces. Since research on narcissism in the Swedish Armed Forces is an unexplored area the research design has an open and unconditional attitude to the research area. This open and explorative approach is achieved through using the method Grounded Theory. The results show that the informants have experienced narcissistic leadership in the Swedish Armed Forces. In addition, the results indicate that such leadership, from a career point of view, can be competitive, but over time is doomed to fail. The empirical data illustrates examples of that military leaders with narcissistic personality traits can advance in the hierarchy and potentially cause harm to the organization. Empirical data also indicates that there are many difficulties associated with identifying narcissists in the Swedish Armed Forces. This can possibly be correlated with the fact that the traits associated with grandiose narcissism substantially overlaps with what we think of as transformational leadership. The aim of the study is relevant since destructive narcissistic leaders annually lead several companies and organizations to ruin, causing great expense and much suffering among their followers.

The aim of this essay is to map, categorize and analyze ghost walks in Swedenduring year 2018-2020. The ghost walks that has been chosen are arranged bycompanies that specializes in ghost walks alone and companies where ghostwalks are one of the products that are offered. To answer the studys purpose andquestions a quantitative method has been used. A chart have been created tocategorize the various ghost walks in Sweden with variables as: Name, year,theme, authenticity and nuance along with three maps. The maps and the chartare the basis of this study created to answer the questions about the diffusion ofghost walks in Sweden, what nuances they have according to Stones (2006) Adark tourism spectrum and the authenticity of the Swedish ghost walks. Theresult is divided into three parts where the questions are answered with the helpof the maps and the chart created for this study. The result of this study revealsthat ghost walks are a relatively wide spread phenomenon in Sweden. 41 ghostwalks were found during this study from the very north of Sweden to the south.At the same time as there are ghost walks in Sweden 70% of them are forentertainment purposes only. This also means that they are on the very brightestpart of the spectrum. 30% were considered to be on the darker part of thespectrum. Along with the mapping and categorizing of the ghost walks togetherwith their nuances the authenticity of the walks were also mapped andcategorized. Based on the results from this study it is clear that ghost walks existin many forms all around Sweden. It is not based on any template which makesthem all unique in their own way. The location of the ghost walk can determinethe theme, but it can just as well not be. This creates a fascinating dark touristphenomenon that can vary in nuances, locations, authenticity and theme.

Longstanding evidence from observational astronomy indicates that non-luminous "dark matter" constitutes the majority of all matter in the universe, yet this mysterious form of matter continues to elude experimental detection. This dissertation presents a search for dark matter at the Large Hadron Collider using 139 fb\(^{-1}\) of proton-proton collision data at a centre-of-mass energy of \(\sqrt{s} = 13\,\)TeV, recorded with the ATLAS detector from 2015 to 2018. The search targets a final state topology in which dark matter is produced from the proton-proton collisions in association with a pair of W bosons, one of which decays to a pair of quarks and the other to a lepton-neutrino pair. The dark matter is expected to pass invisibly through the detector, resulting in an imbalance of momentum in the plane transverse to the beam line. The search is optimized to test the Dark Higgs model, which predicts a signature of dark matter production in association with the emission of a hypothesized new particle referred to as the Dark Higgs boson. The Dark Higgs boson is predicted to decay to a W boson pair via a small mixing with the Standard Model Higgs boson discovered in 2012. Collisions that exhibit the targeted final state topology are selected for the search, and an approximate mass of the hypothetical Dark Higgs boson is reconstructed from the particles in each collision. A search is performed by looking for a deviation between distributions of the reconstructed Dark Higgs boson masses and Standard Model predictions for the selected collisions. The data is found to be consistent with the Standard Model prediction, and the results are used to constrain the parameters of the Dark Higgs model. This search complements and extends the reach of existing searches for the Dark Higgs model by the ATLAS and CMS collaborations. / Graduate

Att göra en användarupplevelse smidig och smärtfri är något som ofta eftersträvas när tillverkare av mjukvara jobbar med design och en produkt som uppnår detta sägs ha en hög användbarhet. Inom spel används på ett liknande sätt begreppet spelbarhet istället, som ett mått på ett spels kvalitet. Alla dessa begrepp ger intrycket av att användarens vilja och mål är i fokus, men det finns också designmönster som har i syfte att skapa beteenden hos användaren som användaren själv kanske inte tycker är önskvärda. Denna studie grundar sig i en denna typen av designmönster, som med avsikt har implementerats för att styra eller vilseleda användaren. Fenomenet har kommit att kallas för Dark Design Patterns. Vårt intresse ligger i att uppmärksamma dessa mönster och diskutera huruvida en utvärdering ämnad för att upptäcka spelbarhetsproblem, också kan upptäcka instanser av dark design patterns. För att ta reda på detta låter vi deltagare utvärdera tre olika mobila gratisspel ur ett spelbarhetsperspektiv som vi också, i en separat granskning, hittar mörka designmönster i. Genom att jämföra resultaten från de olika utvärderingarna kan vi sedan avgöra ifall spelbarhetsutvärderingen kan upptäcka dessa mönster. Det vi kommer fram till är att utvärderingen kan upptäcka vissa tillämpningar av mönster men inte tillräckligt många för att kallas tillförlitlig i detta syfte. Antingen behöver utvärderingen utvecklas eller så får man försöka validera en annan typ av utvärdering ifall man vill kunna identifiera dessa dark design patterns. / Achieving a smooth and pain free user experience is something you often want when designing a new product. A product that achieves this is said to have high usability. In the gaming industry the word playability is used in the same way to describe the general quality of a game. These concepts of usability and playability both take into account the will and wellbeing of the end user, but there is also ways of using design as a way of creating behaviour in the user that doesn’t align with their own will and goals. This paper will study these types of design patterns, which has been implemented with the purpose of controlling and deceiving the user. These kind of patterns are called darkdesign patterns. Our interest lies in highlighting these patterns and whether an evaluation made to find playability problems can, simultaneously, find instances of dark design patterns. In order to find answers to this we let participants do a playability evaluation on different mobile games that we also, in a different examination, had found dark design patterns in. When comparing results from the different tests we could assess whether the playability evaluation successfully identified the different dark design patterns. What we find is that some of the dark design patterns can be found more easily than others. The playability evaluation does not identify enough of the dark design patterns to be called satisfactory in that regard. So you would either need to remodel the evaluation or take a whole new approach if you want to identify all the dark design patterns.

Dark tourism, understood as the type of tourism that relates to a visit to real or recreated places associated with death,suffering,misfortune or the apparently macabre, is not a new concept even from the touristic point of view. As a matter of fact,sites of war, disaster, death and atrocities have always cut the human eye and which made these sites a place curious enough for tourists to visit. As human beings, we have long been drawn either purposefully or if not towards places, attractions or circumstances that are connected in one way or another with death, suffering, violence and disaster. The idea about dark tourism has been designed and studied for the last decade and many were about understanding the motivations behind going or coming a dark tourist and the experiences the dark tourist seeks. But there is little research about the emotions that are involved in dark tourism from the tourist point of view when part-taking in ghost tourism and visiting places and sites that are said to be haunted. This Study focuses on exploring the emotions individuals and tourists seek to experience when they engage in special interest tourism like dark tourism and its experience by visiting haunted attractions. Using a case study of the Baron Palace which is a haunted attraction in Egypt. Studies on emotions are very limited in the tourism industry and talkless of dark tourism which is travelling to sites associated with death, suffering and atrocities.

A new formalism is presented for calculating the mean intensity spectrum and angular power spectrum of gamma-rays or neutrinos from extragalactic annihilating dark matter, taking into account the dependence of the relative motions of the annihilating particles on the annihilation cross section. To model the large scale dark matter distribution of mass and relative velocities, the halo distribution model is comprehensively summarized, and extended to include a universal radial profile of the particles' velocity variance, based on results from N-body computer simulations of dark matter halos. A velocity variance profile, associated with the NFW density profile, is proposed by enforcing a power-law profile of the pseudo phase-space density. This allows the large-scale velocity distribution to be described by virialized, gravitationally bound dark matter halos, as opposed to thermal motions used to describe the velocity distribution in the early Universe. The recent particle motion history of the Universe is presented for the described model. Sample extragalactic gamma-ray intensities from dark matter annihilation are shown for dark matter annihilating with p-wave, according to a relative-velocity-weighted annihilation cross section sigmav = a + bv^2, for constants a and b, with examples taken from supersymmetric models. For thermally produced dark matter, the p-wave suppresses the signal intensity. If b/a > 10^6, the p-wave hardens the intensity spectrum by an estimated factor of 1 + (6b/a)delta_I (E_gamma), and increases the angular power spectrum by a factor also depending on new coefficients (delta_Cl)^(1) (E_gamma ) and (delta_Cl)^(2) (E_gamma ). The energy-dependence of the new p-wave coefficients delta_I , (delta_Cl)^(1) (E_gamma ), and (delta_Cl)^(2) (E_gamma ) are shown for various annihilation spectra. Sample intensity spectra are also presented for Sommerfeld-enhanced annihilation. The intensity of neutrinos from dark matter annihilation is also considered. The variations between the dark matter annihilation signals for different particle phenomenologies suggest that particle physics constraints are possible from an observed indirect detection signal. Calculations of the annihilation signal from the galactic halo are also shown. The extragalactic signal's intensity is found to be consistent in magnitude with the galactic intensity?within the uncertainty of the models of the dark matter distribution?when looking out from the galactic plane. This suggests that the total cosmic signal may have significant contributions from both components.

This thesis addresses the isotropic diffuse gamma-ray background, as measured by the Fermi gamma ray space telescope, and its implications for indirect detection of dark matter. We describe the measurement of the isotropic background, including also an alternative analysis method besides the one published by the Fermi-LAT collaboration. The measured isotropic diffuse background is compatible with a power law differential energy spectrum with a spectral index of  -2.41 ± 0.05 and -2.39 ± 0.08, for the two analysis methods respectively. This is a softer spectrum than previously reported by the EGRET experiment. This rules out any dominant contribution with a significantly different shape, e.g. from dark matter, in the energy range 20 MeV to 102.4 GeV. Instead we present upper limits on a signal originating from annihilating dark matter of extragalactic origin. The uncertainty in the dark matter signal is primarily dependent on the cosmological evolution of the dark matter distribution. We use recent N-body simulations of structure formation, as well as a semi-analytical calculation, to assess this uncertainty. We investigate three main annihilation channels and find that in some, but not in all, of our scenarios we can start to probe, and sometimes rule out, interesting parameter spaces of particle physics models beyond the standard model.We also investigate the possibility to use the angular anisotropies of the annihilation signal to separate it from a background originating from conventional sources, e.g. from active galactic nuclei. By carefully modelling the performance of the Fermi gamma-ray space telescope and galactic foregrounds we find that this method could be as sensitive as using information from the energy spectrum only. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 4: Manuscript.</p>

[EN] Neutrino astronomy is a booming field in astroparticle physics. Due to the particular characteristics of neutrinos, these particles offer great advantages as probes for the study of the far and high-energy Universe. It is extensively accepted by the scientific community that a multi-messenger approach with the combination of information provided by neutrinos, photons and charged particles (cosmic rays) is possible to obtain a more complete image of the fundamental astrophysics processes taking place in our Universe. Since neutrinos are neutral and very weak interacting particles they can reach the Earth from astrophysical sources without deflection by magnetic fields and almost without energy losses and absorption, contrarily to the rest of messengers. The other side of the coin of neutrino properties is that detection of neutrinos is very challenging and big highly instrumented detection volumes are needed. Natural media (deep sea, lakes or ice in the Antarctica) host this kind of experiments using the water (or ice) as target material where the neutrino interaction is produced. ANTARES is the first undersea neutrino telescope, located at 2475 m depth in the Mediterranean Sea. ANTARES is optimized for optical detection of the Cerenkov light induced by relativistic muons produced by high energy neutrino interactions near the detector. The charge, position and arrival time of the photons to the optical modules which compose the detector allows the muon track reconstruction, and thus, knowing the neutrino coming direction. Some information of the event energy is also derived. ANTARES is also hosting the AMADEUS experiment which is investigating the feasibility of the acoustic detection of Ultra-High Energy (UHE) neutrinos. The framework of this thesis is the ANTARES experiment. As commonly done in the thesis developed in this experiment (and in this field), the work has been divided in two different areas. On the one hand, a part more devoted to technological aspects related to the detector and, on the other hand, a part dedicated to ANTARES data analysis. The first part of the thesis is focused in the development of a calibrator able to reproduce the acoustic signal generated in the UHE neutrino interaction with a water nucleus which, roughly speaking, generates a highly directive bipolar acoustic pulse. Having a good calibrator is crucial to test and tune the telescope response for this kind of signals. The second part of the thesis, the data analysis part, is centred in the analysis of the ANTARES data in order to constrain possible Dark Matter models. This work is focused on the detection of products resulting of the Dark Matter annihilation trapped in the centre of the Sun. Specifically, the Secluded Dark Matter (SDM) model has been tested by the detection of di-muons (co-linear muon pair) and/or neutrinos coming from Sun direction. Broadly speaking, this model is based on the idea of the existence of a mediator resulting of the Dark Matter annihilation which, subsequently, would decay into standard model particles as muons or neutrinos. These models have been proposed in order to explain some experimental "anomalies" observed, such as the electron-positron ratio spectrum detected in satellites, measured recently with high accuracy by AMS-II. The study of this thesis constitutes the first search of experimental evidences of this kind of models in neutrino telescopes. / [ES] La astronomía de neutrinos es un campo en auge dentro de la Física de Astropartículas. Los neutrinos ofrecen grandes ventajas como sondas para estudiar el Universo lejano y de alta energía. Es extensamente aceptado que mediante la combinación de la información que proporcionan los neutrinos junto a la obtenida mediante fotones de alta energía (rayos gamma) y partículas cargadas (rayos cósmicos) se podría obtener una imagen más completa de los procesos astrofísicos fundamentales que tienen lugar a lo largo de nuestro Universo.La razón fundamental por la que los neutrinos son tan altamente valorados como mensajeros es la baja interacción con el medio que los rodea. Al ser partículas sin carga interactúan muy débilmente con la materia, por ello pueden escaparse de la fuente donde se han producido y, al contrario de lo que ocurre con el resto de mensajeros, pueden llegar a la Tierra sin ser desviados por los campo magnéticos y sin prácticamente pérdida de energía. Esta misma razón que los hace tan valorados es a su vez la que los hace tan difíciles de detectar. Se impone la necesidad de construir detectores de grandes volúmenes, del orden del km3, altamente instrumentados. Se utilizan medios naturales (en el fondo del mar, en lagos o en enterrados en el hielo de la Antártida) aprovechando el agua (o hielo) como material diana donde se espera que interaccione el neutrino. ANTARES es el primer telescopio submarino de neutrinos construido en el fondo del mar Mediterráneo. Está optimizado para la detección óptica de la luz Cherenkov inducida por los muones relativistas producidos en la interacción de neutrinos de alta energía en los alrededores del detector. La información de la carga, posición y tiempo de llegada de los fotones a los fotomultiplicadores que componen el detector permite tanto la reconstrucción de la trayectoria del neutrino como el conocimiento de su energía. Además, ANTARES acoge el experimento AMADEUS mediante el cual se está investigando y testeando la detección acústica de neutrinos de muy alta energía que, al interaccionar en el agua, producen un pulso termo-acústico que se pretende registrar con una red de hidrófonos. El trabajo desarrollado en esta tesis se engloba bajo el marco del experimento ANTARES. Como es común en las tesis desarrolladas en este experimento, el trabajo se ha dividido en dos áreas diferenciadas: por un lado, una parte de enfoque más tecnológico y, por otro lado, una parte analítica de datos tomados por el telescopio. La primera parte de la tesis está centrada en el desarrollo de un calibrador capaz de reproducir la señal acústica que se emite en la interacción de un neutrino de alta energía con un núcleo de agua que, generalizando, es un pulso bipolar altamente directivo. El disponer de un buen calibrador es clave a la hora de testear la detección acústica en el telescopio y poder sintonizar y "entrenar" los los receptores para este tipo de señales. La segunda parte de la tesis se ha centrado en el análisis de datos registrados por ANTARES con el fin de contrastar posibles modelos astrofísicos para la búsqueda de materia oscura. Este trabajo ha focalizado en la detección de los productos de la aniquilación de materia oscura atrapada en el centro del Sol. Se ha testeado el modelo de Secluded Dark Matter (SDM) a través de la detección de di-muones (pareja de muones co-lineales) y neutrinos en la dirección del Sol. A grandes rasgos, este modelo se basa en la idea de la existencia de un mediador resultado de la aniquilación de materia oscura que posteriormente decaería en partículas del modelo estándar como muones o neutrinos. Estos modelos han sido propuestos con el fin de explicar ciertas 'anomalías' experimentales observadas, tales como el espectro del flujo de positrones detectado en satélites, medido recientemente con gran precisión por AMS-II. realizado en esta tesis constituye la primera búsqueda de evidencias / [CAT] L'astronomia de neutrins és un camp en auge dins la Física d'Astropartícules. Els neutrins ofereixen grans avantatges com a sondes per estudiar l'Univers llunyà i d'alta energia. Es extensament acceptat que mitjançant la combinació de la informació proporcionada pels neutrins junt a la obtinguda mitjançant fotons d'alta energia (rajos gamma) i partícules carregades (rajos còsmics) es podria obtindre una imatge més completa dels processos astrofísics fonamentals que es donen al llarg del nostre Univers. La raó fonamental per la qual els neutrins són altament valorats com a missatgers és la baixa interacció amb el medi que els envolta. Al ser partícules sense càrrega interactuen molt dèbilment amb la matèria, per això poden escapar-se de la font on s'han produït i, al contrari del que ocorre amb la resta de missatgers, poden arribar a La Terra sense desviar-se pels camps electromagnètics i sense pràcticament pèrdua d'energia. Aquesta mateixa raó que els fan tan valorats és al mateix temps la que els fa tan difícil de detectar. S'imposa la necessitat de construir detectors amb grans volums de detecció, de l'ordre del km3, altament instrumentats. S'utilitzen medis naturals (al fons de la mar, en llacs, al gel de l'Antàrtida) aprofitant l'aigua (o el gel) com a material diana on interaccionen el neutrins. ANTARES és el primer telescopi submarí de neutrins construït al fons de la mar Mediterrània. Està optimitzat per a la detecció òptica de la llum de Cherenkov induïda pels muons relativistes produïts en la interacció de neutrins d'alta energia als voltants del detector. La informació de la carrega, posició i temps d'arribada dels fotons als fotomultiplicadors que composen el detector permet tant la reconstrucció de la trajectòria del neutrí, amb gran resolució angular, com el coneixement de la seua energia. A més, ANTARES acull l'experiment AMADEUS mitjançant el qual s'està investigant i testejant la detecció acústica de neutrins de molt alta energia, que, al interaccionar a l'aigua produeixen un pols termo-acústic que es pretén registrar amb una xarxa d'hidròfons. El treball dut a terme en esta tesi s'engloba baix el marc de l'experiment ANTARES. Com es comú en les tesis desenvolupades en aquest experiment, el treball s'ha dividit en dues àrees diferenciades: per una banda una part d'enfocament mes tecnològic i, d'altra banda, una part analítica de les dades preses pel telescopi. La primera part de la tesi està centrada en el desenvolupament d'un calibrador capaç de reproduir la senyal acústica que es genera en la interacció d'un neutrí d'alta energia amb un nucli de l'aigua que, generalitzant, és un pols bipolar altament directiu. Disposar d'un bon calibrador es clau a l'hora de testejar la detecció acústica al telescopi i poder sintonitzar i "entrenar" els receptors a aquest tipus de senyals. La segona part de la tesi, amb caràcter d'anàlisi de dades, s'ha centrat en l'anàlisi de les dades registrades per ANTARES amb el fi de contrastar possibles models astrofísics per a la recerca de matèria fosca. Aquest treball es centra en la detecció dels productes d'aniquilació de matèria fosca atrapada al centre del Sol. En concret, s'ha testejat el model de Secluded Dark Matter (SDM) a través de la detecció de di-muons (parell de muons co-lineals) i neutrins en la direcció del Sol. A grans trets, aquest model es basa en la idea de l'existència d'un mediador resultat de l'aniquilació de matèria fosca que posteriorment decauria en partícules del model estàndard com muons o neutrins. Aquests models han sigut proposats amb la fi d'explicar certes "anomalies" experimentals observades, tals com l'espectre del flux de positrons detectat en satèl¿lits, mesurat recentment amb gran precisió per AMS-II. L'estudi realitzat en esta tesi constitueix la primera recerca d'evidències experimentals d'aquest tipus de models en telescopis de neutrins. / Adrián Martínez, S. (2015).

This study examines the emotional experiences of 152 respondents visiting ‘light’, ‘lighter’, and ‘lightest’ dark tourism sites and the relationship those experiences have with positive word-of-mouth. Therefore, the theoretical contribution of this study fills in the research gap by focusing on the destinations on the ‘lighter’ periphery of Stone’s Dark Tourism Spectrum. The ‘lighter’ destinations which are more commercialized, education- or entertainment-based in nature. In contrast to the destinations on the ‘darker’ periphery of the Dark Tourism Spectrum which are commemorative and where death and tragedy actually occurred. Our results suggest that tourists experience a broad range of both positive and negative emotions when visiting these destinations. Specifically, emotions like Interest, Positive Surprise, Disgust, and Negative Surprise have been found to have a positive relationship with Positive Word-of-Mouth. The results also suggest the practical contribution of this study and confirm that the suppliers of ‘lighter’ destinations are properly managing the dark tourism sites which results in their visitors to spread positive word-of-mouth.
