Complexity and Ambivalence in Ship Safety Inspection : The view of Swedish Port state control officers

Hjorth, Fredrik January 2015 (has links)
Despite an extensive system of Port state controls (PSC) on ships, inspection loopholes in European control functions have been reported. Furthermore, risk factors associated with fatigue, stress and a poorly developed safety culture on board ships have been identified in earlier research. These combined risk factors may pose a serious threat to maritime safety. With this as a point of departure, this thesis aims to investigate the perceived work situation for Swedish inspectors from an inspector’s point of view concerning professional challenges, status and identity for inspectors and the perceived quality of Paris MoU inspection system and the Swedish inspection organization. In this study, the activities of Swedish PSC inspectors are viewed as a profession and the inspectors are viewed as bureaucrats. One of the principals for bureaucracy is that its servants should exercise their authority according to the common good, be autonomous, rational, reliable and responsible. The results indicate that organizational and management reforms have put the PSC bureaucrat under pressure to become more market oriented. Due to the responsibilities inherent in the profession of inspector within the complex structure of shipping, these organizational and management reforms conflict with the PSC inspector’s autonomy and professional role. Inspectors perceive that their expertise and integrity are vital for the success of their work. They also consider the high degree of control that the Swedish inspection organization exercises on the inspectors’ work as limiting to their autonomy and ability to make professional decisions. Some level of control may fulfil a need of support from the Swedish inspection organization, but too much control hampers the professional self-sufficiency and freedom of action. The inspectors in this study reveal considerable ambivalence towards the quality and complexity of ship safety inspections carried out in Sweden and within the Paris MoU system. / <p>The research has been funded by, the Swedish Mercantile Marine Foundation.</p>

Transition of rural household economy in a village of Southern Anhui Province of China 1927-1992

Gao, Jian January 2014 (has links)
Based on primary sources pertaining to the village of Zhaitan, this thesis studied the economic transition of households in a village in the south of Anhui Province as they went through the revolutions, political movements and reforms of the twentieth century. The transition was divided into four periods, corresponding to four of the chapters of this text. The first period was from 1927 to 1949, on which I depicted the household economy in a village that had not yet experienced intervention by the powers of the state; the second period was from 1949 to 1962, during which the Land Reform and the cooperative movement were the most significant revolutions in the rural area. The third period was 1963–1978, when the commune system was adjusted in response to the failure of the Great Leap Forward and was continued stably from then on. The last period was the reform period which ran from late-1978 until 1992. During this period, the collective system was abandoned and state control on the rural economy was gradually loosened. In the course of transition of the household economy in Zhaitan, I focused on the conflict between the growing population and the limited resources of the village. Before the 1949, the solution was to go into businesses outside the village; in the 30 years after 1949, under the framework of the collective system and the control of the state command, the peasants managed to develop labour-intensive production to meet the needs of the growing population; in the reform period after 1978, with the overall withdrawal of state intervention in rural areas, the tension was finally released through the market and the development of industry. The experience of Zhaitan reveals that the change of land ownership did not make a difference to the economic condition of most households if the land area was much less than what was needed. It also shows that the collective system of agriculture, however, could promote agricultural production, and thus brought about positive effects on the condition of each household through centralised management of the labour force and the land. Last, but not least, the overall boost to rural household economy is relient on the development of the industry to complete the transfer of rural workforce from the agriculture.

Inteligentní řídící člen aktivního magnetického ložiska / Inteligent Controller of Active Magnetic Bearing

Turek, Milan January 2011 (has links)
The PhD thesis describes control design of active magnetic bearing. Active magnetic bearing is nonlinear unstable system. This means it is not possible to use classic methods of control design for linear time invariant systems. Also methods of nonlinear control design are not universal and theirs application is not easy task. The thesis describes usage of simple nonlinear compensation which linearizes response of active magnetic bearing and allows usage of classic methods of control design for linear time invariant systems. It is shown that CARLA method can significantly improve parameters of designed controller. First part of thesis describes derivation of model of controlled active magnetic bearing and nonlinear compensation which linearizes response of controlled active magnetic bearing on input signal. Following part contains description of methods of state control design methods, selected methods of robust control design and most common methods of artificial intelligence used for control design and implementation. Next part describes hardware of used experimental device and its parameters. It also contains experimental derivation of model of electromagnetic force because the parameters are not available from manufacturer. Last part describes control design of active magnetic bearing. Several different approaches are described here. The approaches vary from completely experimental approach, through using Ziegler-Nichols method, state control design to methods for robust control design. During design is heavily used CARLA method which is very suitable for usage for online learning in real controller due its principle.

Žemės naudojimo valstybinės kontrolės organizaciniai ir teisiniai aspektai / Organizational and legal aspects of state control of land use

Bražinskaitė, Simona 22 January 2009 (has links)
Norint nustatyti, ar žemė naudojama racionaliai ir tikslingai, vykdoma žemės naudojimo valstybinė kontrolė. Žemės naudojimo valstybine kontrole siekiama užtikrinti, kad valdant ir naudojant žemę, būtų laikomasi Lietuvos Respublikos žemės įstatymo bei kitų įstatymų, kurie susiję su žemės naudojimo priežiūra. Siekiant užtikrinti tinkamą žemės naudojimą, tenka išspręsti nemažai įvairių problemų. Tyrimas atliktas siekiant nustatyti žemės naudojimo valstybinės kontrolės darbų organizavimo problemas, trukdančias pasiekti efektyvų kontrolės vykdymą. Tyrimo metu buvo išanalizuoti žemės naudojimą ir valstybinės kontrolės vykdymą reglamentuojantys teisės aktai, Nacionalinės žemės tarnybos prie Žemės ūkio ministerijos ir Marijampolės apskrities viršininko administracijos Žemės tvarkymo departamento kontrolės vykdymo veiklos ataskaitos. Kylančios problemos vykdant žemės naudojimo valstybinę kontrolę Marijampolės apskrityje nustatytos išanalizavus teisės aktus, jų praktinį taikymą ir kontrolės vykdymo veiklos ataskaitas. Tyrimo metu panaudoti literatūros šaltinių analizės, alternatyvų paieškos, lyginamosios ir vertinamosios analizės ir loginio mąstymo metodai. Nustatyta, kad apskričių viršininkų administracijos vykdoma žemės naudojimo valstybinė kontrolė nėra pakankamai efektyvi ir neskatina taupiai naudoti žemę. Tai paaiškintina pareigūnų kompetencijos trūkumu ir nesureguliuotomis jų funkcijomis – vykdoma kita veikla su kontrole nesusijusiose srityse. Baigiantis žemės reformos darbams... [toliau žr. visą tekstą] / In order to determine whether the land is used rationally and purposefully, state control of land use is performed. By the state control of land use one strives to ensure that while managing and using land, the land law and other laws of the Republic of Lithuania related to land use care are obeyed. In order to ensure the appropriate use of land, one has to solve many different problems. The research was carried out in order to find out the problems of state control of land use that prevent from effective control implementation. During the research one analyzed the use of land and legal acts that regulate state control implementation and control implementation work reports of National Land Service under the Ministry of Agriculture and Marijampole county governor’s administration Land Managing Department. The problems that rise while implementing state control of land use in the county of Marijampole were determined by analyzing legal acts, their practical application and work reports of control implementation. During the research one used the analysis of literature sources, alternative search, comparative and evaluation analyses and methods of logical thinking. It was determined that state control of land use that is performed by county governor’s administration is not quite effective and does not encourage using land economically. This can be explained by the lack of competence of officials and their unadjusted functions, i.e. work is performed in other spheres that are not... [to full text]

Biometrics: A New Mean of Surveillance and Migration Control

Kajevic, Belhira January 2006 (has links)
We live in an era of advanced technological innovations and it is therefore difficult to acquire a proper overview of the different surveillance techniques deployed for the purpose of enhancing and administrating migration control. The intent of this paper is to disseminate one of the new technologies on the market: the biometric technology that is an identification and verification system based on measurements of biological traits. Different approaches are used to explore and investigate the technological functions, social structures and political justifications for their validity and their role in the implementation of the biometric technology. The paper also provides an overview of the different areas of political and social management that are affected by the implementation of the biometric techniques.The principal aim of this work is to examine how the implementation of the biometric techniques will affect privacy for all people, taking both information privacy and personal integrity into consideration. The second question deals with migration management, as the current implementation mainly involves travel documents. It focuses on the consequences of the so-called war on terror and its call for prevention of terrorism and irregular migration. The dilemma between national security and the right to privacy, public good and private interests, and the realms of state and individual rights are also discussed and analysed.Hence, the framework and the fundamental structure of this thesis are based on three core issues pertinent to the implementation of biometrics in the EU: threats posed on the right to privacy, securitization of migration, and intensification of surveillance and state control. The findings are used to identify the threats posed on right to privacy and the way this right is compromised, and the consequences of practices and policies in the field of migration that are discriminatory and exclusory. Lastly, by employing different theories, this paper examines why state seeks technological control over citizens and why individuals comply with state control and surveillance.

Hur införandet av MLC har påverkat anmärkningar under hamnstatskontroller

Mansnerus, Anton, Wernius, Pontus January 2017 (has links)
Syftet med undersökningen var att undersöka om antalet anmärkningar och typer av anmärkningar hade förändrats sedan införandet av MLC. Undersökningsmaterialet är hämtat från Paris MoU årliga rapporter. Det var utifrån dessa som undersökningen genomfördes. Slutsatserna som vi kom fram till var, att sedan MLC infördes har totala antalet anmärkningar minskat under perioden 2011 till 2015.  Antal nyttjandeförbud har också minskat. Anmärkningar som endast berör arbetsmiljön har minskat sedan införandet av MLC. Allt fler anmärkningar, som tidigare hamnat under ILO, hamnar nu under MLC. De mest förekommande MLC anmärkningarna var ”Records of Seafarers´daily hours of work or rest” och ”Electrical”. Den vanligaste MLC anmärkningen som resulterade i nyttjandeförbud var ”Wages”. De anmärkningar som var vanligast vid en hamnstatskontroll beträffande övriga anmärkningar var ”Fire Safety” och ”Safety of Navigation”. / The aim of the study was to investigate whether the number of complaints and the types of complaints had changed since the introduction of the MLC. The research material is taken from the Paris MoU annual reports. It was from these that the survey was conducted. The conclusions that we came to was, that since the MLC was introduced, the total number of complaints have decreased during the period 2011-2015. The number of detentions have also declined. Remarks concerning only the work environment has declined since the introduction of the MLC. An increasing number of complaints, which had previously fallen under the ILO, will settle in the MLC.  The most common MLC remarks were "Records of Seafarers'daily hours of work or rest" and "Transport". The most common MLC complaint that resulted in the retention was "Wages". The remarks that were common at the Port State Control regarding the other allegations were "Fire Safety" and "Safety of Navigation".

Fartyg från grå- och svartlistade flaggstater som trafikerar Sveriges närområde : En analys av samband mellan flaggstater, klassningssällskap och potentiella miljöhot / Vessels from flag states listed as grey and black that navigate in or near Swedish coastal areas : An analysis of correlations between flag states, classification societies and potential threats to the environment

Kristoffersson, Jessica, Brandt, Ellinor January 2019 (has links)
Paris Memorandum of Understanding (MoU) utfärdar varje år listor över hur väl flaggstater presterar vid hamnstatskontroller, uppdelade i en vit, en grå och en svart lista, där den svarta listan visar de flaggstater vars fartyg belagts med kvarstad flest gånger. Med hjälp av deskriptiv statistik analyserades fartyg som seglat under en flagg som presenteras på Paris MoUs svarta och grå lista, och som trafikerat Östersjön och Västerhavet. Arbetet baseras på data från 841 fartyg som trafikerade Östersjön och Västerhavet mellan åren 2013 och 2017. Studien undersöker om det finns något som utmärker fartygen, hur ofta de byter flagg och om det finns ett samband mellan flaggstater och klassningssällskap. Det som framgick var att fartyg som tillhör svart- eller grålistade flaggstater kan utgöra ett potentiellt hot för den svenska närmiljön, då nästan hälften av de fartyg som undersöktes har fått miljörelaterade anmärkningar i rapporterna från hamnstatskontroller. Fartygen är även äldre än genomsnittet för världshandelsflottan och vid flaggbyten byter de oftare till flaggstater som har en lägre prestanda med avseende på hamnstatskontroller. Det visade sig dessutom finnas ett samband mellan klassningssällskap som har en sämre rankning av Paris MoU och fartyg tillhörande svartlistade flaggstater. / Each year, Paris Memorandum of Understanding (MoU) issues lists of how well flag states perform in Port State Controls, divided into a white, a grey and a black list, where the black list displays the flag states with the largest ratio of detentions. This study uses descriptive statistics to analyse vessels that have sailed under flags presented in the Paris MoU grey and black lists and have trafficked the Baltic Sea, Kattegatt and Skagerrak. The study is based on data from 841 vessels that trafficked the area during the years 2013 to 2017. It investigates if there is anything that distinguishes the vessels, how often they change flags and if there is a connection between flag states and classification societies. The study found that vessels registered under flag states presented in the grey or black list can pose a potential threat to the Swedish marine environment, as nearly half of the examined vessels had received environment related observations during Port State Controls. The vessels were also older than the world fleet average and when changing flags they often changed to flag states with a lower ranking according to Paris MoU. A relationship between classification societies with a lower ranking according to Paris MoU and vessels from blacklisted flag states was also discovered.
