The Rural Households. Case Study. Cheia Village, Mihai Viteazu Commune, Cluj County
Vasile SURD,Leonard BRUCKNER,Adina-Maria PU?CA?U
Journal of Settlements and Spatial Planning , 2011,
Abstract: After 1989, fundamental changes in agricultural structures occurred as a consequence of the setting up of Land Law no. 18/1991 along with other subsequent regulations. Excessive concentration of property before 1989 took a new twist, pertaining to excessive fragmentation, therefore the shift from large areas of land to small farms nowadays. But the farmer received only land without machinery or equipment necessary to its efficient operation. In this paper we want to highlight the specific state of rural economic life in Romania after extinctions of political communist economy system and after almost the entire destruction of infrastructure and facilities left from the former political system (decommissioning and destruction of irrigation system, the abandoning of tractors and agricultural equipment buildings, of chemical fertilizer production). Therefore, we aim to highlight the present economic state of a village in Cluj County and its households.
Decision-Making and Georgia's Perpetual Revolution: The Case of IDP Housing
Till Bruckner
Caucasian Review of International Affairs , 2009,
Abstract: Observers tend to enthuse about Georgia’s leadership or damn it, but such black-and-white views do little to explain what is really going on in the country. Examining the government’s recent efforts to provide housing to those internally displaced by the August 2008 conflict with Russia sheds light not only on the housing program itself, but on contemporary Georgian politics in general. In particular, four traits characteristic of the ruling United National Movement’s revolutionary governance are brought into focus: informal decision-making, fluid roles, heroic action, and vanguard politics.
A Model Structure On The Category Of Small Acyclic Categories
Roman Bruckner
Mathematics , 2015,
Abstract: In this paper, we show that the Thomason model structure restricts to a Quillen equivalent cofibrantly generated model structure on the category of acyclic categories, whose generating cofibrations are the same as those generating the Thomason model structure. To understand the Thomason model structure, we need to have a closer look at the (barycentric) subdivision endofunctor on the category of simplicial sets. This functor has a well known right adjoint, called Kan's Ex functor. Taking the subdivision twice and then the fundamental category yields a left adjoint of an adjunction between the category of simplicial sets and the category of small categories, whose right adjoint is given by applying the Ex functor twice on the nerve of a category. This adjunction lifts the cofibrantly generated Quillen model structure on simplicial sets to a cofibrantly generated model structure on the category of small categories, the Thomason model structure. The generating sets are given by the image of the generating sets of the Quillen model structure on simplicial sets under the aforementioned adjunction. We furthermore show that the category of acyclic categories is proper and combinatorial with respect to said model structure. That is weak equivalences behave nicely with respect to pushouts along fibrations and cofibrations, and cofibrations satisfy certain smallness conditions which allow us to work with sets instead of proper classes.
On Valuing Constant Maturity Swap Spread Derivatives  [PDF]
Leonard Tchuindjo
Journal of Mathematical Finance (JMF) , 2012, DOI: 10.4236/jmf.2012.22020
Abstract: Motivated by statistical tests on historical data that confirm the normal distribution assumption on the spreads between major constant maturity swap (CMS) indexes, we propose an easy-to-implement two-factor model for valuing CMS spread link instruments, in which each forward CMS spread rate is modeled as a Gaussian process under its relevant measure, and is related to the lognormal martingale process of a corresponding maturity forward LIBOR rate through a Brownian motion. An illustrating example is provided. Closed-form solutions for CMS spread options are derived.
Lifestyles and Their Impact on Energy-Related Investment Decisions  [PDF]
Maria Gr?ger, Victoria Schmid, Thomas Bruckner
Low Carbon Economy (LCE) , 2011, DOI: 10.4236/lce.2011.22014
Abstract: This paper presents an empirical survey of energy-related investment decisions made by private households in Germany. The investment behaviour is segmented and discussed by applying the milieu approach. The decision makers are clustered in certain lifestyles, as represented by the Sinus-Milieus® from the Sinus Institute. To analyse the relationship between the lifestyles of house owners and their energy-related investment decisions, telephone interviews were conducted in order to acquire data on currently installed heating systems and preferences for future heating systems in private residential buildings. The results of the survey support the hypothesis of a link between lifestyles and the energy-related investment behaviour. Based on the observed relationship between lifestyles and decisions on energy technologies, predictions of energy trends in private residential buildings can be improved. In addition, the knowledge about specific development paths allows the utilisation of the information for information campaigns and the promotion of energy supply technologies which lead to lower CO2-emissions.
The recent decline of Montastraea annularis (complex) coral populations in western Cura?ao: a cause for concern?
Bruckner,A. W; Bruckner,R. J;
Revista de Biología Tropical , 2006,
Abstract: shallow leeward reefs off the western end of cura?ao are dominated by extensive populations of m. annularis (complex). these species are larger in size (mean= 66 cm diameter) than all other species, with few small colonies (<30 cm) and notable absence of recruits. in 1998, colonies of m. annularis (complex) accounted for more then 45% of all species >10 cm observed within transects, and most exhibited low levels of partial mortality (mean= 22.5%). these species were less abundant (38% of all colonies) in 2005. partial mortality among live colonies of m. annularis and m. faveolata increased by 85% (mean = 42% partial mortality) and numerous dead colonies of m. faveolata and m. annularis were observed; m. franksi colonies were generally in excellent condition (14% partial tissue mortality). a high prevalence of coral diseases (3-30%) was documented among m. annularis and m. faveolata, while all other species were less frequently affected. yellow band disease (ybd) emerged shortly after the 1995 bleaching event, and rapidly spread throughout all depths, with the highest prevalence between 1997-1999. ybd caused slow rates of mortality (=1 cm/month), but multiple focal lesions appeared on individual colonies, and these progressively radiated outward as they killed the colonies. by 2005, 44% of the tagged corals were dead; the remainder exhibited active ybd infections (21%) or were in remission (31.6%) but were missing on average >90% of their tissue. although the incidence of ybd has declined since 2000, white plague (wp) prevalence was unusually high (4-12%) in 2001 and 2005, with affected colonies exhibiting recent mortality of up to 70%. dead montastraea spp. surfaces are being colonized by other corals, including poritids, agaricids, and other faviids, while recruits of m. annularis (complex) are absent. if diseases and other biotic stressors persist on these reefs, m. annularis and m. faveolata populations may undergo a decline similar to that observed in the 1980s
The recent decline of Montastraea annularis (complex) coral populations in western Cura ao: a cause for concern?

Abstract: Shallow leeward reefs off the western end of Cura ao are dominated by extensive populations of M. annularis (complex). These species are larger in size (mean= 66 cm diameter) than all other species, with few small colonies (<30 cm) and notable absence of recruits. In 1998, colonies of M. annularis (complex) accounted for more then 45% of all species >10 cm observed within transects, and most exhibited low levels of partial mortality (mean= 22.5%). These species were less abundant (38% of all colonies) in 2005. Partial mortality among live colonies of M. annularis and M. faveolata increased by 85% (mean = 42% partial mortality) and numerous dead colonies of M. faveolata and M. annularis were observed; M. franksi colonies were generally in excellent condition (14% partial tissue mortality). A high prevalence of coral diseases (3-30%) was documented among M. annularis and M. faveolata, while all other species were less frequently affected. Yellow band disease (YBD) emerged shortly after the 1995 bleaching event, and rapidly spread throughout all depths, with the highest prevalence between 1997-1999. YBD caused slow rates of mortality (=1 cm/month), but multiple focal lesions appeared on individual colonies, and these progressively radiated outward as they killed the colonies. By 2005, 44% of the tagged corals were dead; the remainder exhibited active YBD infections (21%) or were in remission (31.6%) but were missing on average >90% of their tissue. Although the incidence of YBD has declined since 2000, white plague (WP) prevalence was unusually high (4-12%) in 2001 and 2005, with affected colonies exhibiting recent mortality of up to 70%. Dead Montastraea spp. surfaces are being colonized by other corals, including poritids, agaricids, and other faviids, while recruits of M. annularis (complex) are absent. If diseases and other biotic stressors persist on these reefs, M. annularis and M. faveolata populations may undergo a decline similar to that observed in the 1980s among Caribbean acroporids. Rev. Biol. Trop. 54 (Suppl. 3): 45- 58. Epub 2007 Jan. 15. Los arrecifes someros a sotavento del oeste de Cura ao están dominados por extensas poblaciones de Montastraea annularis (complejo). Estas especies son mayores en tama o (promedio= 66 cm de diámetro) que las otras especies, con algunas colonias peque as (<30 cm) y una notable ausencia de reclutas. En 1998, las colonias de Montastraea annularis (complejo), representaban más del 45% de todas las especies de >10 cm observadas en transectos y la mayoría exhibió bajos niveles de mortalidad parcial (prom= 22.5%).
Detection of infectious disease outbreaks in twenty-two fragile states, 2000-2010: a systematic review
Catherine Bruckner, Francesco Checchi
Conflict and Health , 2011, DOI: 10.1186/1752-1505-5-13
Abstract: We identified 61 reports concerning 38 outbreaks. Twenty of these were detected by existing surveillance systems, but 10 detections occurred following formal notifications by participating health facilities rather than data analysis. A further 15 outbreaks were detected by informal notifications, including rumours.There were long delays from onset to detection (median 29 days) and from detection to further events (investigation, confirmation, declaration, control). Existing surveillance systems yielded the shortest detection delays when linked to reduced barriers to health care and frequent analysis and reporting of incidence data.Epidemic surveillance and control appear to be insufficiently timely in fragile states, and need to be strengthened. Greater reliance on formal and informal notifications is warranted. Outbreak reports should be more standardised and enable monitoring of surveillance systems' effectiveness.The World Bank describes a fragile state as a country 'facing particularly severe development challenges such as weak institutional capacity, poor governance, political instability, and frequently ongoing violence or the legacy effects of past severe conflict' [1].In 2009, 29 countries were considered fragile, comprising a sixth of the world's population [2,3]. Fragile states generally feature poor health indicators, high malnutrition prevalence, scarcity of skilled health workers and worsening rates of extreme poverty [4-6]. Their populations are also highly vulnerable to infectious disease outbreaks, a reflection of inadequate government services and armed conflict-related phenomena such as forced displacement [7]. It has been suggested that most major epidemics worldwide occur in complex emergency and/or natural disaster settings [8].Detection and early containment of outbreaks in these settings is also challenging, as highlighted by the Global Polio Eradication Initiative's recent setbacks in several fragile states, where genetic analysis has demonst
The importance of the marine ornamental reef fish trade in the wider Caribbean
Bruckner,A.W;
Revista de Biología Tropical , 2005,
Abstract: the marine ornamental fish trade began in the 1930s in sri lanka,spread to hawaii and the philippines in the 1950s,and expanded to a multi-million dollar industry in the 1970s with fisheries established throughout the tropical pacific,indian and atlantic oceans.currently,45 countries supply global markets an estimated 14-30 million fish annually,with an import value of us$28-44 million.the largest suppliers are indonesia and the philippines,followed by brazil,maldives,vietnam,sri lanka and hawaii.in the tropical western atlantic,16 countries have export fisheries, including the u.s.(florida and puerto rico).the u.s.is the world ?s largest buyer,followed by the european union and japan.the global trade consists of over 1400 species of reef fishes,of which only about 25 are captive bred on a commercial scale.damselfish,anemonefish, and angelfish constitute over 50%of the global volume; butterflyfish, wrasses,blennies,gobies,triggerfish,file-fish,hawkfishes,groupers and basselets account for 31%of the trade,and the remaining 16%is represented by 33 families.the most important fishes from the caribbean are angelfish (six species), seahorses (two species), royal gramma, jawfish,queen triggerfish,redlip blenny,puddingwife,bluehead wrasse,and blue chromis.the caribbean currently supplies a small percentage of the global trade in marine ornamental species,but ornamental fisheries in this region represent important emerging industries.it is critical that effective ornamental fishery management plans and regulations are developed and enforced,and fishery-dependent and fishery-independent data are collected and utilized in decision making processes to ensure sustainable ornamental fisheries throughout the region.
ACTIVITY ANALYSIS WITH HIDDEN MARKOV MODEL FOR AMBIENT ASSISTED LIVING
GuoQing Yin,Dietmar Bruckner
International Journal of Electronic Commerce Studies , 2012,
Abstract: In an Ambient Assisted Living (AAL) project the activities of the user will be analyzed. The raw data is from a motion detector. Through data processing the huge amount of dynamic raw data was translated to state data. With hidden Markov model, forward algorithm to analyze these state data the daily activity model of the user was built. Thirdly by comparing the model with observed activity sequences, and finding out the similarities between them, defined the best adapt routine in the model. Furthermore an activity routine net was built and used to compare with the hidden Markov model.
