Counterfactual thinking in the wake of trauma
Creators: name: Davis, Christopher G.
Publisher: name: University of British Columbia
Year: 2009

description: Counterfactuals generated by people who have experienced traumatic life events were examined to elucidate their significance for the coping process. In Study 1, 93 respondents were interviewed 4-7 years after the loss of their spouse or child in a motor vehicle accident. In Study 2, 124 respondents were interviewed 3 weeks and 18 months following the death of their child to Sudden Infant Death Syndrome. Across these two studies it was found that (a) counterfactuals that undid the traumatic event were commonly reported; (b) the focus of counterfactuals was typically on one's own (in)actions, rather than on the behavior of others; (c) the more freguently respondents were undoing the event, the more distress they reported; and (d) this relation held even after controlling for more general ruminations. In Study 3, 106 respondents were interviewed one week following their spinal cord injury. In this study, self-implicating counterfactuals were shown to predict ascriptions of self-blame, controlling for causal attributions and foreseeability estimates. Taken together, these field data suggest that counterfactuals play an important role in how people cope with traumatic life events. Possible roles that these counterfactual thoughts might play are discussed.

description: The nonlinear quantum interaction of a linearly polarized x-ray probe beam with a focused intense standing laser wave is studied theoretically. Because of the tight focusing of the standing laser pulse, diffraction effects arise for the probe beam as opposed to the corresponding plane wave scenario. A quantitative estimate for realistic experimental conditions of the ellipticity and the rotation of the main polarization plane acquired by the x-ray probe after the interaction shows that the implementation of such vacuum effects is feasible with future X-ray Free Electron Laser light.

description: We investigate the impact of pre-main sequence stellar luminosity evolution on the thermal and chemical properties of disc midplanes. We create template disc models exemplifying initial conditions for giant planet formation for a variety of stellar masses and ages. These models include the 2D physical structure of gas as well as 1D chemical structure in the disc midplane. The disc temperature profiles are calculated using fully physically consistent radiative transfer models for stars between 0.5 and 3 Msun and ages up to 10 Myr. The resulting temperature profiles are used to determine how the chemical conditions in the mid-plane change over time. We therefore obtain gas and ice-phase abundances of the main carbon and oxygen carrier species. While the temperature profiles produced are not markedly different for the stars of different masses at early stages (<1 Myr), they start to diverge significantly beyond 2 Myr. Discs around stars with mass >1.5 Msun become warmer over time as the stellar luminosity increases, whereas low-mass stars decrease in luminosity leading to cooler discs. This has an observable effect on the location of the CO snowline, which is located >200 au in most models for a 3 Msun star, but is always within 80 au for 0.5 Msun star. The chemical compositions calculated show that a well defined stellar mass and age range exists in which high C/O gas giants can form. In the case of the exoplanet HR8799b, our models show it must have formed before the star was 1 Myr old.
Structure and stability of the magnetic solar tachocline

description: Rather weak fossil magnetic fields in the radiative core can produce the solar tachocline if the field is poloidal and almost horizontal in the tachocline region, i.e. if the field is confined within the core. This particular field geometry is shown to result from a shallow (B_p^-1/2 with the poloidal field amplitude falling below 5% of the solar radius for B^p > 5 mG. The resulting toroidal field amplitude inside the tachocline of about 100 G does not depend on the B^p. The hydromagnetic stability of the tachocline is only briefly discussed. For the hydrodynamic stability of latitudinal differential rotation we found that the critical 29% of the 2D theory of Watson (1981) are reduced to only 21% in 3D for marginal modes of about 6 Mm radial scale.

description: We investigate Steel's conjecture in 'The Core Model Iterability Problem', that if $W$ and $R$ are $Ω+1$-iterable, $1$-small weasels, then $W\leq^{*}R$ iff there is a club $C\subsetΩ$ such that for all $α\in C$, if $α$ is regular, then the cardinal successor of $α$ in $W$ is less or equal than the cardinal successor of $α$ in $R$ . We will show that the conjecture fails, assuming that there is an iterable premouse which models $KP$ and which has a $Σ_{1}$-Woodin cardinal. On the other hand, we show that assuming there is no transitive model of $KP$ with a Woodin cardinal the conjecture holds.
 In the course of this we will also show that if $M$ is an iterable admissible premouse with a largest, regular, uncountable cardinal $δ$, and $\mathbb{P}$ is a forcing poset with the $δ$-c.c. in $M$, and $g$ is $M$-generic, but not necessarily $Σ_{1}$-generic, $M[g]$ is a model of $KP$. Moreover, if $M$ is such a mouse and $T$ is maximal normal iteration tree on $M$ such that $T$ is non-dropping on its main branch, then $M_{\infty}^{T}$ is again an iterable admissible premouse with a largest regular and uncountable cardinal. At last we answer another open question from 'The Core Model Iterability Problem' regarding the S-hull property.

Characterisation of stochastic low-frequency variability in 50 massive stars
Creators: name: Pedersen, May Gade

Publisher: name: Zenodo
Year: 2024

description: The advent of photometric space telescopes has revealed that stochastic low-frequency (SLF) variability is a common type of variability found in massive stars. Here we analyse the TESS data for 50 massive stars showing SLF variability; 49 of which are found across six different Cygnus OB associations and one from the Small Magellanic Cloud (SMC). The SLF signal is characterised using two different methods and compared to a sample of 53 O- and B-type stars which have previously been studied in the literature. We find that SLF variability of the lower metallicity SMC star shows similar characteristics as the 102 Galactic stars. Furthermore, we find a significant correlation between the spectroscopic luminosity of our sample of 49 Cygnus OB stars and the amplitudes and slopes of their SLF variability, while no similar significant correlation is found for the characteristic frequency.

description: We present near-IR photometry and spectroscopy of 30 extremely luminous radio and mid-IR selected galaxies. With bolometric luminosities exceeding $\sim10^{13}$ $\rm{L_{\odot}}$ and redshifts ranging from $z = 0.880-2.853$, we use VLT instruments X-shooter and ISAAC to investigate this unique population of galaxies. Broad multi-component emission lines are detected in 18 galaxies and we measure the near-IR lines $\rm{H\rmβ}$, $\text{[OIII]}\rmλ\rmλ4959,5007$ and $\rm{H\rmα}$ in six, 15 and 13 galaxies respectively, with 10 $\rm{Lyα}$ and five CIV lines additionally detected in the UVB arm. We use the broad $\text{[OIII]}\rmλ5007$ emission lines as a proxy for the bolometric AGN luminosity, and derive lower limits to supermassive black hole masses of $10^{7.9}$-$10^{9.4}$ $\text{M}_{\odot}$ with expectations of corresponding host masses of $10^{10.4}$-$10^{12.0}$ $\text{M}_{\odot}$. We measure $\rmλ_{Edd}$ > 1 for eight of these sources at a $2σ$ significance. Near-IR photometry and SED fitting are used to compare stellar masses directly. We detect both Balmer lines in five galaxies and use these to infer a mean visual extinction of $A_{V}$ = 2.68 mag. Due to non-detections and uncertainties in our $\rm{H\rmβ}$ emission line measurements, we simulate a broad $\rm{H\rmβ}$ line of FWHM = 1480 $\rm{kms^{-1}}$ to estimate extinction for all sources with measured $\rm{H\rmα}$ emission. We then use this to infer a mean $A_{V}=3.62$ mag, demonstrating the highly-obscured nature of these galaxies, with the consequence of increasing our estimates of black-hole masses by an 0.5 orders of magnitude in the most extreme and obscured cases.

description: Noise in a quantum system is fundamentally governed by the statistics and the many-body state of the underlying particles. Whereas for bosonic particles the correlated noise observed for e.g. photons or bosonic neutral atoms can still be explained within a classical field description with fluctuating phases, the anticorrelations in the detection of fermionic particles have no classical analogue. The observation of such fermionic antibunching is so far scarce and has been confined to electrons and neutrons. Here we report on the first direct observation of antibunching of neutral fermionic atoms. Through an analysis of the atomic shot noise in a set of standard absorption images, of a gas of fermionic 40K atoms released from an optical lattice, we find reduced correlations for distances related to the original spacing of the trapped atoms. The detection of such quantum statistical correlations has allowed us to characterise the ordering and temperature of the Fermi gas in the lattice. Moreover, our findings are an important step towards revealing fundamental fermionic many-body quantum phases in periodic potentials, which are at the focus of current research.

description: Traditionally, finite differences and finite element methods have been by many regarded as the basic tools for obtaining numerical solutions in a variety of quantum mechanical problems emerging in atomic, nuclear and particle physics, astrophysics, quantum chemistry, etc. In recent years, however, an alternative technique based on the semi-spectral methods has focused considerable attention. The purpose of this work is first to provide the necessary tools and subsequently examine the efficiency of this method in quantum mechanical applications. Restricting our interest to time independent two-body problems, we obtained the continuous and discrete spectrum solutions of the underlying Schroedinger or Lippmann-Schwinger equations in both, the coordinate and momentum space. In all of the numerically studied examples we had no difficulty in achieving the machine accuracy and the semi-spectral method showed exponential convergence combined with excellent numerical stability.

description: Spin Matrix theory (SMT) limits provide a way to capture the dynamics of the AdS/CFT correspondence near BPS bounds. On the string theory side, these limits result in non-relativistic sigma models that can be interpreted as novel non-relativistic strings. This SMT string theory couples to non-relativistic $U(1)$-Galilean background geometries. In this paper, we explore the relation between pp-wave backgrounds obtained from Penrose limits of AdS${}_5 \times S^5$, and a new type of $U(1)$-Galilean backgrounds that we call flat-fluxed (FF) backgrounds. These FF backgrounds are the simplest possible SMT string backgrounds and correspond to free magnons from the spin chain perspective. We provide a catalogue of the $U(1)$-Galilean backgrounds one obtains from SMT limits of string theory on AdS${}_5 \times S^5$ and subsequently study large charge limits of these geometries from which the FF backgrounds emerge. We show that these limits are analogous to Penrose limits of AdS${}_5 \times S^5$ and demonstrate that the large charge/Penrose limits commute with the SMT limits. Finally, we point out that $U(1)$-Galilean backgrounds prescribe a symplectic manifold for the transverse SMT string embedding fields. This is illustrated with a Hamiltonian derivation for the SMT limit of a particle.

description: The use of stibnite (Sb2S3) as sensitizers in the solid-state sensitized solar cells received considerable research interest during the transition of the millennium. However, the use of perovskite diminished the research in the field and the potential of antimony chalcogenide (Sb2(S,Se)3) was not explored thoroughly. Although these materials also provide bandgap tuning like perovskite by varying the composition of S and Se, it is not as popular as perovskite mainly because of the low efficiency of the solar cells based on it. In this paper, we present a landscape of the functional role of various device parameters on the performance of Sb2(S,Se)3 based solar cells. For the purpose, we first calibrate the optoelectronic model used for the simulation with the experimental results from the literature. The model is then subjected to parametric variations to explore the performance metrics for this class of solar cells. Our results show that despite the belief that open circuit voltage is independent of contact layers doping in proper band aligned sensitized solar cells, here we observe otherwise and the open circuit voltage is indeed dependent on the doping density of the contact layers. Using the detailed numerical simulation and analytical model we further identify the performance optimization map of Sb2(S,Se)3 based sensitized solar cells.

description: Point-contact (PC) spectroscopy measurements on YNi2B2C single crystals in the normal and superconducting (SC) state (T_c=15.4K) for the main crystallographic directions are reported. The PC study reveals the electron-phonon interaction (EPI) function with a dominant maximum around 12meV and a further weak structure (kink or shallow broad maximum) at higher energy at about 50meV. Other phonon maxima at 20, 24 and 32meV specified in the phonon DOS of YNi2B2C by neutron measurements [PRB, V.55, 9058 (1997)] are not resolved in the PC spectra pointing out to the main role of the low energy phonon modes in EPI. Directional study of the SC gap results in Δ_[100]=1.5meV for the a- direction and Δ_[001]=2.4meV along the c-axis which may point to anisotropic and/or multiband behavior. Noteworthy, the critical temperature T_c in all cases corresponds to that of bulk samples. The value 2Δ_[001]/kT_c=3.6 is close to the BCS one of 3.52, and the temperature dependence Δ(T) is BCS-like, while for the a-direction Δ(T) deviates from mean-field BCS behavior above T_c/2. The directional variation in Δcan be attributed to the multiband nature of the SC state in YNi2B2C predicted 10 years ago (PRL, V.80, 1730 (1998)).

Quine on opacity in modal and doxastic contexts
Creators: name: Dickson, Mark William
Publisher: name: University of British Columbia
Year: 2009

description: Quine has been mainly opposed to sentences that feature cross-quantification. That is, he is critical of sentences that involve quantifying into a context that Quine labels 'opaque1. Quine's opposition to cross-quantification grew out of an earlier attack on the notion of combining quantification theory and modal logic. Quine initially dismissed, in 1943, cases of quantifying into modal contexts as meaningless. Later in the same year, Alonzo Church argued that there was a meaningful way to quantify into modal contexts, thus vindicating the notion that quantification theory could be merged with modal logic. In 1956, in "Quantifiers and Propositional Attitudes," Quine pointed out that quantification into belief contexts, though indispensable, also features the improper quantification into opaque contexts. In the same paper, Quine introduced the distinction between a relational and a notional sense of propositional attitude ascriptions. The former sense concerns the problematic sentences that feature cross-quantification. In the thesis that follows, I appropriate Quine's terminology and critically evaluate his reasons for rejecting the relational idiom in both modal and doxastic contexts. Such an evaluation reveals some startling results in the philosophy of language. One of the major problems that Quine sought to address was that of reconciling the evident significance of instances of the relational idiom with their many alleged difficulties. Quine restricted himself to acknowledging the idiom's meaningfulness in doxastic contexts. Most of Quine's criticisms of the relational idiom are argued by me to be unsound. It is contended that some of Quine's criticisms involve the improper exploitation of ambiguities inherent in such sentences. This fallacy is exposed and subjected to a critical evaluation. The exposure of this fallacy, which I term 'the relational fallacy' is a novel contribution to the philosophy of language. Another novel contribution to the philosophy of language is my critique of Quine's use of semantic ascent to account for intuitively meaningful relational modal sentences. A third, slightly less novel, contribution to the philosophy of language involves extending Quine's temporary view that there are meaningful relational sentences in doxastic contents to the analogous observation that there are meaningful relational sentences in modal contexts.

Τα αποτελέσματα έδειξαν ότι η μέτρια άσκηση έχει στατιστικώς σημαντική συνεισφορά στην πρόγνωση, της αυτοεκτίμησης, της συμπεριφοράς του παιδιού και στο πόσο επηρεάζει η υγεία ή η συμπεριφορά του παιδιού τον γονέα, ως διαστάσεις της ποιότητας ζωής. Ωστόσο, οι διαστάσεις της ποιότητας ζωής στην πρόγνωση των οποίων η έντονη άσκηση έδειξε στατιστικώς σημαντική συνεισφορά είναι η ευεξία, η αυτοεκτίμηση, και το πόσο πολύ επηρεάζεται ο γονέας λόγω της συμπεριφοράς του παιδιού του.
description: It is well established that physical activity positively affects quality of life. Despite the large number of studies examining the effect of physical activity on quality of life and health-related quality of life, no study to date has examined the relationship of physical activity to health-related quality of life among adolescents. The purpose of this study was to investigate the relationship of physical activity to health-related quality of life at various levels of exercise intensity in adolescents aged 13-16 years. For the purpose of this survey the Child Health Questionnaire and the Godin Leisure Time Exercise Questionnaire were used. Linear regression showed that moderate exercise had a statistically significant contribution to the prediction of self-esteem, child's behavior, and on how much parents are affected by the child’s health or behavior. On the other hand, the dimensions of quality of life associated with intense exercise were child’s well-being, self esteem, and how much the parent was affected by the behavior of their child.

description: This paper presents an analytical study of TM-polarized surface plasmon polaritons (SPPs) in nonlinear multi-layer structures containing graphene sheets. In the general structure, each graphene sheet has been sandwiched between two different nonlinear magnetic materials. To show the richness of the proposed general waveguide, two novel nonlinear structures have been introduced and investigated as special cases of the general structure. It will be shown that the propagation features of these structures can be tuned by changing the chemical potential of the graphene and the incident mode power. A large value of the effective index, i.e. 240 for the chemical potential of 0.2 ev and the incident power of 3 is obtained for the second structure at the frequency of 40 THz. The analytical results confirm that the integration of nonlinear magnetic materials with graphene sheets can control and enhance the propagating features and the self-focused of the field in the nonlinear layer. This integration gives more degrees of freedom to the designer to propose new THz components such as lasers and switches in the THz region.

The lower bound is at least five orders of magnitude larger than the expected value of this parameter and can be tested by LHC physics.

description: In this work we study the transport properties of hybrids that consist of exchange biased ferromagnets (FMs) combined with a low-Tc superconductor (SC). Not only different FMs but also various structural topologies have been investigated: results for multilayers of La(1-x)CaxMnO3 combined with Nb in the form of [La0.33Ca0.67MnO3/La0.60Ca0.40MnO3]15/Nb, and for more simple Ni80Fe20/Nb/Ni80Fe20 trilayers and Ni80Fe20/Nb bilayers are presented. The results obtained in all hybrid structures studied in this work clearly uncover that the exchange bias mechanism promotes superconductivity. Our findings assist the understanding of the contradictory results that have been reported in the recent literature regarding the transport properties of relative FM/SC/FM spin valves.

description: Given a graph $G=(V,E)$, a function $f:V\rightarrow \{0,1,2\}$ is a total Roman $\{2\}$-dominating function if: (1) every vertex $v\in V$ for which $f(v)=0$ satisfies that $\sum_{u\in N(v)}f(u)\geq 2$, where $N(v)$ represents the open neighborhood of $v$, and (2) every vertex $x\in V$ for which $f(x)\geq 1$ is adjacent to at least one vertex $y\in V$ such that $f(y)\geq 1$. The weight of the function $f$ is defined as $ω(f)=\sum_{v\in V}f(v)$. The total Roman $\{2\}$-domination number, denoted by $γ_{t\{R2\}}(G)$, is the minimum weight among all total Roman $\{2\}$-dominating functions on $G$. In this article we introduce the concepts above and begin the study of its combinatorial and computational properties. For instance, we give several closed relationships between this parameter and other domination related parameters in graphs. In addition, we prove that the complexity of computing the value $γ_{t\{R2\}}(G)$ is NP-hard, even when restricted to bipartite or chordal graphs.

description: Additional file 1: Table S1. LifeX radiomic features description according to the Imaging Biomarker Standardization Initiative (IBSI) description (update 17 December 2019). LifeX version was 4.81. Figure S1. Box plots showing the distribution of SUVmax (panel A) and Volume (panel B). Figure S2. (A) Bar diagrams of intra-class correlation coefficient (ICC) values of RFs for robustness to SUVmax thresholding. Bars show the median ICC between the different segmentations for the absolute intensity rescale factor AR60. Range error bars (in black) encompass the lowest and highest values for different operators. (B) Boxplot of COVL for different threshold (20, 30, 40%) for each RFs, for the first operator (results superposable for the other operators). TLG (total lesion glycolysis) conventional parameter in our study corresponds to the TLSRE (total lesion somatostatin receptor expression). Figure S3. Radiomic features with moderate or poor consistency (ICC < 0.80), but high agreement (median COVL < 10%) to intensity discretization. The RFs were: GLCM_Entropy_log2, GLCM_Entropy_log10 (not shown), GLRLM_SRE, GLRLM_LRE and GLRLM_RP. Value of the RFs for each lesion are presented in the top row; boxplots of COVL for the first operator are presented in the bottom row. Figure S4. Radiomic features with high consistency (ICC > 0.90), but low agreement (median COVL > 10%) to SUVmax thresholds (0, 20, 30 and 40%). The RFs were: GLRLM_LGRE, GLRLM_SRLGE, GLZLM_LGZE and GLZLM_LZLGE. Value of the RFs for each lesion are presented in the top row; boxplots of COVL for the first operator are presented in the bottom row. Figure S5. Boxplot showing the distribution of RF value for each operator. The three RFs chosen are the most representative of the impact of segmentation on ICC. Segmentation did not affect SUVmean (A) and TLG (B) in terms of ICC, although TLG was characterized by not negligible dispersion (percentage of COVL) in our study. In contrast, segmentation had a high impact on GLZLM_SZLGE (C) in terms of both ICC and COVL. Mean COVL of SUVmean, TLG and GLZLM_SZLGE was 8.33±3.96, 13.38±8.52 and 30.67±27.29, respectively.

Entropy Production in a Cell and Reversal of Entropy Flow as an Anticancer Therapy
Creators: name: Luo, Liaofu
Publisher: name: arXiv
Year: 2008
Subjects: subject: Cell Behavior (q-bio.CB)
subject: FOS: Biological sciences

description: The entropy production rate of cancer cell is always higher than healthy cell under the case of no external field applied. Different entropy production between two kinds of cells determines the direction of entropy flow among cells. The entropy flow is the carrier of information flow. The entropy flow from cancer to healthy cell takes along the harmful information of cancerous cell, propagating its toxic action to healthy tissues. We demonstrate that a low-frequency and low-intensity electromagnetic field or ultrasound irradiation may increase the entropy production rate of a cell in normal tissue than that in cancer, consequently reverse the direction of entropy current between two kinds of cells. The modification of PH value of cells may also cause the reversal of the direction of entropy flow between healthy and cancerous cells. So, the biological tissue under the irradiation of electromagnetic field or ultrasound or under the appropriate change of cell acidity can avoid the propagation of harmful information from cancer cells. We suggest that this entropy mechanism possibly provides a basis for a novel approach to anticancer therapy.

Deconstruction and other approaches to supersymmetric lattice field theories

description: This report contains both a review of recent approaches to supersymmetric lattice field theories and some new results on the deconstruction approach. The essential reason for the complex phase problem of the fermion determinant is shown to be derivative interactions that are not present in the continuum. These irrelevant operators violate the self-conjugacy of the fermion action that is present in the continuum. It is explained why this complex phase problem does not disappear in the continuum limit. The fermion determinant suppression of various branches of the classical moduli space is explored, and found to be supportive of previous claims regarding the continuum limit.

description: Στόχος αυτής της διπλωματικής εργασίας ήταν η προσέγγιση της σύγχρονης εκδοχής των πρακτικών μετασχηματισμού του σώματος στην πόλη της Θεσσαλονίκης. Οι δύο βασικές πρακτικές μετασχηματισμού που αναλύθηκαν και εξετάστηκαν περαιτέρω είναι το τατουάζ και το πίρσινγκ. Σε συνδυασμό με παλαιότερες εθνογραφικές αναφορές και μαρτυρίες έγινε μια παρουσίαση των σκοπών, των στόχων ,των διαδικασιών και των αιτιών που εξασκούνται τέτοιου είδους πρακτικές και διακοσμήσεις από τα αρχαία χρόνια μέχρι σήμερα. Η επιτόπια έρευνα στα τατού στούντιο, που βρίσκονται στην Θεσσαλονίκη και που διήρκησε περίπου έξι μήνες, αποτέλεσε την βασικότερη πηγή για την εκπόνηση αυτής της εργασίας. Οι συνεντεύξεις των εργαζόμενων στα τατού στούντιο αλλά και αρκετών επισκεπτών και πελατών καθώς και η συμμετοχική παρατήρηση υπήρξαν τα μεθοδολογικά εργαλεία που εμπλούτισαν την εργασία με ενδιαφέρουσες πληροφορίες για τον κόσμο του τατουάζ και του πίρσινγκ και γενικότερα για τον κόσμο των τροποποιημένων και διακοσμημένων σωμάτων. Επιπλέον περιλαμβάνονται περιγραφές και πληροφορίες για τις τεχνικές διαδικασίες του τατουάζ και του πίρσινγκ , τα εργαλεία που χρησιμοποιούνται και τα σχέδια των τατουάζ που επιλέγονται. Τέλος ο μετασχηματισμός του ενσώματου εαυτού αναλύεται μέσα από τους όρους του συμβολισμού, της σεξουαλικότητας, της μόδας, της εξατομίκευσης και της ένταξης, της συμμόρφωσης και της αντίστασης, της διαφορετικότητας και της περιθωριοποίησης.
description: The aim of this thesis was the approach of modern version of the practical transformation of the body in the city of Thessaloniki. The two main practical transformations that were analyzed and considered further are the tattooing and the piercing. In combination with earlier ethnographic reports and testimonies there was a presentation of goals, objectives, processes and reasons that such decorations are practiced since ancient times until today. The fieldwork in tattoo studios, located in Thessaloniki and lasted about six months was the main source for the preparation of this thesis. The interviews of the employees in the tattoo studio but also of several visitors and customers plus the participant observation were the methodological tools that have enriched the dissertation with interesting information about the world of tattooing and piercing and the world of the modified and decorated bodies. Additionally there are included descriptions and information on the technical procedures of tattooing and piercing, the tools that are used and the designs of the tattoo that are being chosen. Finally, the transformation of the embodied self is analyzed through the terms of symbolism, sexuality, fashion, personalization and integration, of compliance and resistance, of diversity and marginalization.

description: Social media enables users to publish, disseminate, and access information easily. The downside is that it has fewer gatekeepers of what content is allowed to enter public circulation than the traditional media. In this paper, we present preliminary empirical findings from WeChat, a popular messaging app of the Chinese, indicating that social media users leverage their friend networks collectively as latent, dynamic gatekeepers for content consumption. Taking a mixed-methods approach, we analyze over seven million users' information consumption behaviors on WeChat and conduct an online survey of $216$ users. Both quantitative and qualitative evidence suggests that friend network indeed acts as a gatekeeper in social media. Shifting from what should be produced that gatekeepers used to decide, friend network helps separate the worthy from the unworthy for individual information consumption, and its structure and dynamics that play an important role in gatekeeping may inspire the future design of socio-technical systems.

description: Οι συνεχείς εξελίξεις στην τεχνολογία αλλά και η επέλαση της παγκοσμιοποίησης, έχουν οδηγήσει τις επιχειρήσεις να καταφεύγουν συχνά στην εξωτερίκευση των δραστηριοτήτων τους (outsourcing). Κύριος στόχος της παρούσας διπλωματικής εργασίας είναι η μελέτη της σχέσης παραγωγού – υπεργολάβου, κυρίως από την οπτική γωνία του παραγωγού, δηλαδή η διαδικασία επιλογής υπεργολάβου, η συνεργασία αλλά και η διαχείριση των κινδύνων που ενυπάρχουν και των προβλημάτων που πιθανώς θα ανακύψουν. Παράλληλα, η παρούσα εργασία αποτελεί μία βιβλιογραφική ανασκόπηση των βασικότερων δημοσιεύσεων γύρω από το ζήτημα αυτό.
description: The ongoing progress in technology and the spreading globalization have forced enterprises to outsource some or all of their activities. In this project, an effort was made to investigate the relationship between a producer and its subcontractors, that is, to investigate the procedure of choosing a subcontractor, the form of cooperation that takes place between a producer and its subcontractors but also the problems that may arise. At the same time, the present work is a literature review of the fundamental papers concerning the abovementioned issues.
