La tesi affronta il tema del diritto di controllo del socio di s.r.l., sviluppando, nel primo capitolo, l'analisi dell'evoluzione storico-normativa del diritto di controllo individuale. Dopo aver esposto le elaborazioni dottrinali che hanno esaminato la diversa estensione quali-quantitativa del diritto in questione nelle sue diverse manifestazioni, dall'art. 2261 c.c. fino all'art. 2422 c.c., si rintraccia nella posizione del socio amministrato rispetto alla vocazione ad amministrare l'elemento capace di determinare la misura e il contenuto del controllo nei differenti tipi sociali. Il rapporto tra l'ampiezza del diritto di controllo e la qualità di socio amministrato nelle differenti tipologie societarie può essere letto in termini di proporzionalità diretta: il diritto di controllo, infatti, è tanto più ampio quanto maggiore è lo spazio riservato, seppur in potenza, al socio nel governo della società. L'estensione massima del diritto in esame, in attesa di una riforma della disciplina delle società di persone, è raggiunta nell'art. 2476, secondo comma, c.c. e la ratio di una tale ampiezza del diritto di controllo si rinviene nella volontà del legislatore di livellare la posizione del socio amministrato di s.r.l. su quella del socio amministratore, almeno sotto il profilo dell'accesso all'informazione. Oggetto del secondo capitolo è l'estensione contenutistica del controllo, l'indagine del rapporto tra controllo e informazione e l'analisi dell'attività di controllo in termini di processo che si articola in più fasi. Ciò chiarito si aprono una serie di problemi che riguardano principalmente quanta e quale informazione dare o permettere di acquisire ed entro quali limiti. A tal proposito l'analisi giunge alla conclusione secondo cui il diritto in questione non incontra nessun limite salvo quello, seppur non espresso, della buona fede. Nel terzo capitolo si leggono le riflessioni in merito ai soggetti coinvolti nello scambio informativo disciplinato dall'art. 2476, secondo comma, c.c. e i possibili risvolti patologici del rapporto tra il singolo socio non amministratore e gli amministratori, individuati nel loro insieme (salvo il caso di amministratore unico), in qualità di soggetti tenuti a fornire le informazioni richieste e a consentire la consultazione. L'analisi si conclude, nel quarto capitolo, con una serie di argomentazioni sul tema del rapporto tra l'autonomia statutaria e il diritto di controllo. L'inderogabilità del diritto in questione è affermata sulla base di argomentazioni tratte dall'intera disciplina della s.r.l., dal rinnovato ruolo che l'informazione assume nel tipo sociale in esame come valore fondante che contribuisce a delineare il nuovo ruolo del socio che non partecipa all'amministrazione, nonché dall'individuazione di alcune norme in cui l'informazione è sottintesa o espressamente richiesta. / The object of the study is the shareholder's right of control in the Italian limited liability company ( s.r.l. ). In the first chapter this right is analysed focusing on the historical development of relevant laws. The element capable of determining the extent and the content of the control in the different types of company has to be individuated in the position of the managed shareholder compared to the vocation to manage the company. The relationship between the extent of the right of control and the quality of managed shareholder in the different types of company can be read in term of direct proportionality: the right of control, in fact, is as wider as the space potentially reserved to the shareholder in the management of the company is greater. Maximum extent of the mentioned right, pending a reform of the partnerships, is reached in art. 2476, second subparagraph, Italian civil code ( c.c. ). The legislator would to level the position of the managed shareholder of s.r.l. to that one of the managing shareholder, at least regarding the right to access information. The second chapter deals with the extent of the content of control, the survey of the relationship between control and information and the analysis of control activity in term of process articulating in more stages. This clarification opens a series of issues which concern mainly how much and what information the directors must give or permit to acquire and within what limits. In this respect the analysis concludes that the right in object has not any limits except that one, although not expressed, of good faith. In third chapter we read the comments with regard to subjects involved in the exchange of information governed by art. 2476, second subparagraph, c.c., and the possible pathological aspects of the relationship between each non managing shareholder and directors, identified as a whole (except in the case of sole director), and in quality of persons liable to provide the information required and to allow consultations. The analysis concludes, in the last chapter, with a series of arguments about the relationship between the right granted to the shareholder in determining the Bylaw and the right of control. The unavoidability of the right in object is established on the basis of arguments drawn from the whole discipline of s.r.l., from the renewed role that the information takes within s.r.l. as founding value that contributes to outline the new role of the shareholder who is not director, as well as from identification of certain rules where information is implied or expressly requested.

Målet med denna uppsats är att bidra till kvalitetsutveckling gällande behovsbedömning och beslutsformulering vid handläggning enligt socialtjänstlagen. Syftet med uppsatsen är att granska handläggningsprocessen gällande boendestödsbeslut. Med utgångspunkt i denna granskning vill vi komma fram till förslag på förbättringsområden. Förslagen ska vara förenliga med krav från och behov hos lagstiftaren, den enskilde, socialtjänsten/kommunen och biståndshandläggaren. Beslut om boendestöd är idag tidsbegränsade, oftast till ett år, utan att den enskilde egentligen ansökt om det. För den enskilde stödmottagaren innebär detta bristande rättssäkerhet, otrygghet och brist på kontinuitet. Vi har i denna uppsats försökt kartlägga skälen till att besluten ser ut på detta sätt genom att tillämpa en hermeneutisk metod. Av vår genomgång framgår att det inte finns stöd för rutinmässig tidsbegränsning av beslut i lagstiftningen. I vissa fall, där det kan förutses att behovet förändras över tid, kan det dock vara motiverat. Målgruppen för boendestöd har ofta långvariga funktionsnedsättningar och stödbehov som kan antas kvarstå över längre tid än ett år. Enligt de kommunala riktlinjer som vi har granskat är boendestöd en insats som ska tidsbegränsas. De biståndshandläggare som vi har tillfrågat tidsbegränsar i 80 procent av fallen beslut om boendestöd till en giltighetstid på upp till ett år. Det huvudsakliga skälet till detta är att biståndshandläggarna anser att det underlättar uppföljning av besluten. Resultatet av vår studie pekar på att ett antal åtgärder skulle kunna öka kvaliteten på behovsbedömning och beslut om boendestöd. Dessa innebär främst implikationer för kommun, socialtjänst och biståndshandläggare att arbeta vidare med i syfte att skapa en mer rättssäker och evidensbaserad biståndshandläggning. / The intention of this study is to contribute to quality enhancement regarding needs assessment and shaping of decisions of the social service called living support (i.e. boendestöd) according to the law of social service. The aim of this study is to review the process of needs assessment concerning living support. Based on this review we want to give suggestions to possible improvements. Our suggestions must be compatible with demands and requirements from the lawmaker, the individual, the social service/the municipality and the process officer. Today, decision of living support is time limited, usually to a year, without the individual actually having applied for it. This leads to a lack of legal security, personal security and continuity for the individual. In this study, we have tried to locate the reasons for why the decisions are constructed in this way by using a hermeneutical method. Our study shows no support for perfunctory time limiting of decisions according to the law. In some cases where there can be forecasted that the need changes over time, it can though be motivated. The target group for living support often have prolonged impairments and needs of support highly estimated to last more than a year. According to municipal guidelines, reviewed by us, living support is an inset to be time limited. The process officers we have asked in 80 per cent of all cases time limits the decisions up to one year. The main reason for this is that the process officers regard time limiting as making follow-ups of the decisions easier. The result of our study points to a number of measures for increasing the quality of needs assessment and decisions of living support. These measures have implications for the municipality, the social services and the process officers with the purpose of creating a more legally secure and evidence based process of needs assessment.

A corpus of terms for human beings collected from 18th century novels is studied from a broad sociolinguistic perspective. A summary of recent linguistic theories and a survey of 18th century culture and society are provided as background. The basic assumption is that the meaning of words is dependent on human beings and their society and that shifts in meaning are linked to changes in attitudes, culture and social structure. Terms used for men and women therefore mirror the concepts of 'male' and 'female' in a society. Gender differences found in various semantic fields are presented and discussed. Prototypes for certain terms are suggested by means of frame analysis. Sense developments are traced and related to societal changes. Differences in male and female usage are discussed. The findings are analyzed in terms of the following contrasts within the concepts of 'male' and 'female': spirit/matter; power/dependency; active/passive; varied/limited. / digitalisering@umu

In modern low pressure plasma discharges, the electron mean free path often exceeds the device dimensions. Under such conditions the electron velocity distribution function may significantly deviate from Maxwellian, which strongly affects the discharge properties. The description of such plasmas has to be kinetic and often requires the use of numerical methods. This thesis presents the study of kinetic effects in inductively coupled plasmas and Hall thrusters carried out by means of particle-in-cell simulations. The important result and the essential part of the research is the development of particle-in-cell codes. <p>An advective electromagnetic 1d3v particle-in-cell code is developed for modelling the inductively coupled plasmas. An electrostatic direct implicit 1d3v particle-in-cell code EDIPIC is developed for plane geometry simulations of Hall thruster plasmas. The EDIPIC code includes several physical effects important for Hall thrusters: collisions with neutral atoms, turbulence, and secondary electron emission. In addition, the narrow sheath regions crucial for plasma-wall interaction are resolved in simulations. The code is parallelized to achieve fast run times. <p>Inductively coupled plasmas sustained by the external RF electromagnetic field are widely used in material processing reactors and electrodeless lighting sources. In a low pressure inductive discharge, the collisionless electron motion strongly affects the absorption of the external electromagnetic waves and, via the ponderomotive force, the density profile. The linear theory of the anomalous skin effect based on the linear electron trajectories predicts a strong decrease of the ponderomotive force for warm plasmas. Particle-in-cell simulations show that the nonlinear modification of electron trajectories by the RF magnetic field partially compensates the effects of electron thermal motion. As a result, the ponderomotive force in warm collisionless plasmas is stronger than predicted by linear kinetic theory. <p>Hall thrusters, where plasma is maintained by the DC electric field crossed with the stationary magnetic field, are efficient low-thrust devices for spacecraft propulsion. The energy exchange between the plasma and the wall in Hall thrusters is enhanced by the secondary electron emission, which strongly affects electron temperature and, subsequently, thruster operation. Particle-in-cell simulations show that the effect of secondary electron emission on electron cooling in Hall thrusters is quite different from predictions of previous fluid studies. Collisionless electron motion results in a strongly anisotropic, nonmonotonic electron velocity distribution function, which is depleted in the loss cone, subsequently reducing the electron wall losses compared to Maxwellian plasmas. Secondary electrons form two beams propagating between the walls of a thruster channel in opposite radial directions. The secondary electron beams acquire additional energy in the crossed external electric and magnetic fields. The energy increment depends on both the field magnitudes and the electron flight time between the walls. <p>A new model of secondary electron emission in a bounded plasma slab, allowing for emission due to the counter-propagating secondary electron beams, is developed. It is shown that in bounded plasmas the average energy of plasma bulk electrons is far less important for the space charge saturation of the sheath than it is in purely Maxwellian plasmas. A new regime with relaxation oscillations of the sheath has been identified in simulations. Recent experimental studies of Hall thrusters indirectly support the simulation results with respect to the electron temperature saturation and the channel width effect on the thruster discharge.

<p>Eligibility for antiretroviral therapy (ART) in HIV-infected patients is defined either by a cluster of differentiation antigen 4 (CD4) count of less than 200cells/mm3 or clinical diagnosis of WHO stage III and IV. Therefore, the decision to start ART becomes difficult when CD4 cell count is not available. With limited laboratory infrastructure, the decision to start ART is usually made based on clinical symptoms leading to late commencement of ART. This calls for alternative criteria to see if nail discoloration (ND) correlates with low CD4 count among untreated HIV infected patients. This will serve as a complementary screening tool for identifying asymptomatic ARV naive HIV patients with a CD4 cell count of less than 200cells/mm3 which signifies&nbsp / severe immunosuppression. Study Design and Setting: This was a quantitative cross-sectional descriptive and analytical study involving adult ART na&iuml / ve HIV infected patients in WHO stage I and II. Systematic sampling was used to select the participants from all adult ART na&iuml / ve HIV infected patients attending APIN clinic, located at the Jos University Teaching Hospital (JUTH), Jos, Nigeria. Data Collection: Face-to-face interviews, physical examination and relevant laboratory investigations with selected participants were conducted using a questionnaire guide. Questions on socio-demographic characteristics, clinical data, general physical examinations including finger nail examination and photographing with subsequent laboratory investigations including CD4 count and western blot were employed. Data Analysis: Variables were categorized and data analyzed using descriptive statistics including the frequency, percentage frequency / mean and standard deviation of continuous variables. Association between CD4 count of &le / 200cells/mm3 and ND was tested using the chisquare test with an alpha level of 0.05. Prevalence of ND, sensitivity, specificity, positive predictive and negative predictive values and accuracy of the screening test of ND was calculated. Results: 394 patients had their fingernails photographed and assessed. It was shown that distal banded and grey nails were the common types of ND seen with a prevalence of 38%. There was an association between CD4 count &le / 200cells/mm3 and ND (p&lt / 0.0001). CD4 count &le / 200cells/mm3 was a risk factor for developing ND (RR=2.3[1.8-3.6]). The association has a sensitivity of 78%, specificity of 55%, positive predictive value of 50%, and negative predictive value of 80% and accuracy of test 63%. Conclusion: With a significant association (p&lt / 0.0001) and a sensitivity of 78%, ND can be a useful clinical indicator of immune dysfunction mediated by HIV among patients in WHO stage I or II. ND can either be a clinical sign or a symptom in HIV patients with a CD4 of &le / 200cells/mm3 as seen in the study as the specificity and sensitivity of ND compared favourably with other WHO stage III diagnosis. Recommendations: Nail discoloration should complement CD4 count as an additional staging sign to help identify patients likely to benefit from ART especially in resource-limited settings. Finally, all patients with grey or distal banded should be on co-trimoxaxole prophylaxis in line with WHO /national guideline on the use of co-trimoxaxole for all HIV positive patients with a CD4 cell count of &le / 350cells/mm3.</p>

Multiple-input multiple-output (MIMO) systems have received much attention due to their multiplexing and diversity capabilities. It is possible to obtain remarkable improvement in spectral efficiency for wireless systems by using MIMO based schemes. However, sophisticated equalization and decoding structures are required for reliable communication at high rates. In this thesis, capacity achieving practical transceiver structures are proposed for MIMO wireless channels depending on the availability of channel state information at the transmitter (CSIT). First, an adaptive MIMO scheme based on the use of quantized CSIT and reduced precoding idea is proposed. With the help of a very tight analytical upper bound obtained for limited rate feedback (LRF) MIMO capacity, it is possible to construct an adaptive scheme varying the number of beamformers used according to the average SNR value. It is shown that this strategy always results in a significantly higher achievable rate than that of the schemes which does not use CSIT, if the number of transmit antennas is greater than that of receive antennas. Secondly, it is known that the use of CSIT does not bring significant improvement over capacity, when similar number of transmit and receive antennas are used / on the other hand, it reduces the complexity of demodulation at the receiver by converting the channel into noninterfering subchannels. However, it is shown in this thesis that it is still possible to achieve a performance very close to the outage probability and exploit the space-frequency diversity benefits of the wireless fading channel without compromising the receiver complexity, even if the CSIT is not used. The proposed receiver structure is based on iterative forward and backward filtering to suppress the interference both in time and space followed by a spacetime decoder. The rotation of multidimensional constellations for block fading channels and the single-carrier frequency domain equalization (SC-FDE) technique for wideband MIMO channels are studied as example applications.

This dissertation seeks to merge the ideas from robust control theory such as H-Infinity control design and the Small Gain Theorem, L stability theory and Lyapunov stability from nonlinear control, and recent theoretical achievements in adaptive control. The fusion of frequency domain and linear time domain ideas allows the derivation of an H-Infinity Norm Minimization Approach (H-Infinity-NMA) for adaptive control architecture that permits a control designer to simplify the adaptive tuning process and tune the uncertainty compensation characteristics via linear control design techniques, band limit the adaptive control signal, efficiently handle redundant actuators, and handle unmatched uncertainty and matched uncertainty in a single design framework. The two stage design framework is similar to that used in robust control, but without sacrificing performance. The first stage of the design considers an ideal system with the system uncertainty completely known. For this system, a control law is designed using linear H-Infinity theory. Then in the second stage, an adaptive process is implemented that emulates the behavior of the ideal system. If the linear H-Infinity design is applied to control the emulated system, it then guarantees closed loop system stability of the actual system. All of this is accomplished while providing notions of transient performance bounds between the ideal system and the true system. Extensions to the theory include architectures for a class of output feedback systems, limiting the authority of an adaptive control system, and a method for improving the performance of an adaptive system with slow dynamics without any modification terms. Applications focus on using aerodynamic flow control for aircraft flight control and the Crew Launch Vehicle.

L’offerta di servizi di microcredito da parte di istituzioni di microfinanza contribuisce ad aumentare l’accesso al credito di una clientela rurale ed accrescere l’efficienza dei mercati locali del credito? Questo studio prova a rispondere alla precedente domanda attraverso lo sviluppo di un modello teorico e l’analisi empirica sulla base di dati raccolti in un villaggio dell’Etiopia. In un mercato finanziario duale (formale/informale), il modello teorico indica che, nonostante non tutti i membri dell’ accordo informale ottengano un microcredito dall’intermediario formale, ogni membro dell’istituzione informale ne beneficia. Infatti, i membri che si trovano in condizione di deficit finanziario beneficiano direttamente di maggiori risorse derivanti dal prestito mentre gli altri membri godono di vincoli di partecipazione meno stringenti. Inoltre, quando il tasso di interesse sui prestiti formali si riduce, aumenta sia l’utilità dei prenditori di fondi che quella di tutti gli altri membri dell’istituzione informale. Gli intermediari formali sottraggono mercato alle istituzioni informali in una misura che dipende dall’ammontare del microcredito e dal tasso di interesse. I dati raccolti nel villaggio rurale etiope confermano solo parzialmente le considerazioni teoriche. In primo luogo, a causa di un diverso ammontare e di una diversa scadenza dei prestiti formali rispetto a quelli informali, nel villaggio i due mercati sembrano complementari. In secondo luogo, l’approccio del prestito di gruppo sembra replicare gli stessi processi di monitoraggio e selezione delle istituzioni informali e pertanto le famiglie a basso reddito rimangono vincolate nell’accesso al credito. In conclusione, se le istituzioni di microfinanza volessero operare con successo nelle aree rurali, dovrebbero, per prima cosa, studiare i processi di selezione dei membri all’interno delle istituzioni informali e, per seconda cosa, offrire una più ampia gamma di prodotti finanziari oltre al credito, come ad esempio prodotti di risparmio e prodotti assicurativi. / Does the provision of formal microcredit increase access to credit of rural clients and efficiency of credit markets? This study tackles this question through the development of a theoretical model and an empirical analysis in an Ethiopian village. In a dual (formal/informal) financial market, the theoretical model suggests that when some members of the informal arrangement get a formal loan, all members benefit from it. The agents who have a current deficit have greater financial resources whereas the agents who have an expected future deficit enjoy looser participation constraints. Furthermore, when the interest rate charged on formal loans decreases, the utility of not only borrowing members but all members in the arrangement increases. Besides, the formal market crowds out the informal market to some extent as long as the formal loan size increases or the interest rate decreases. Evidence from the rural village in southern Ethiopia only weakly confirms the theoretical results because of two reasons. First, due to different size and maturity of loans, the formal microcredit services and the informal risk sharing arrangements appear to be complements in the local market. Second, the group lending approach seems to replicate the same selection and monitoring processes of the informal arrangements and the low-income households remain constrained in their access to credit. Therefore, MFIs that want to operate successfully in rural areas should, first, make an assessment of self-selection processes in the informal arrangements and, second, provide a wider range of financial products besides credit, such as savings and insurance products.

Unter den bösartigen Tumoren hat das Bronchialkarzinom wohl die dramatischste Entwicklung genommen. Die Inzidenz und Mortalität ist in den letzten 15-20 Jahren bei Männern zwar leicht rückläufig, für Frauen ist jedoch ein entgegen gesetzter Trend zu erkennen. Dies wird in erster Linie auf die veränderten Lebensgewohnheiten, wie steigender Zigarettengenuss unter den Frauen, zurückgeführt. Derzeit gibt es in Deutschland circa 20 Millionen Raucher, von denen etwa 140˙000 jährlich an den Folgen ihres Inhalationsrauchens versterben...
