Full textAbstract:
Studies have found that housing with energy performance certificates have a positive premium in sales price. However, other studies have obtained negative or unexpected results. The objective of this study is to determine whether or not housing with energy performance certificates (EPC) have positive premiums in the sales price. For this purpose, a systematic review, meta-analysis, and meta-regression of prior studies were conducted in order to determine whether the existence of an EPC influences sales price. A total of 66 documents were examined, with a total of 173 sales registers. The impact of having or not having an EPC was analyzed for housing sales price premiums on a global level, as well as the premiums in Europe for each of the ABCDEFG qualification letters. The results suggest that: 1) Globally speaking, it is estimated that housing with an EPC has an overall price premium of 4.20%, on a continent level, with premiums of 5.36% being obtained in North America, 4.81% in Asia, and 2.32% in Europe; 2) in Europe, the results are not conclusive with regards to the ABCDEFG qualification, since there is no consensus as to the letter base to be used as a reference for comparisons, thereby generating small comparable samples.

Full textAbstract:
Objective This retrospective study aimed to explore the appropriate application and implications of Mental Health Act 2007 (NSW) (MHA) certificate use in a metropolitan generalist hospital in New South Wales. Methods A de-identified MHA certificate review was undertaken within acute generalist medical and surgical specialties between June 2012 and May 2013. To assess differences, data were separated into two categories according to whether certificates were completed by psychiatry trainees or generalist medical officers. Analysis of indications for detention was also undertaken and qualitatively matched against legislative criteria. Results A total of 43 MHA certificates were included in the review, which highlighted missing elements in most certificates. Differences were found when professional consensus by the researchers was used to match documentation to legislative criteria. The researchers disagreed with nine of the 16 indications (mental illness/mental disorder) by the generalist medical officers and only one indication by a psychiatry trainee. Six of the certificates appeared to be related to lack of capacity and need for treatment of medical conditions, thus more related to Guardianship Act 1987 (NSW) applications. Conclusion This study highlights inconsistencies in legislative knowledge and requirements between professional groups. Education and training opportunities have been identified to ensure greater consistency in application of the MHA, preservation of patient rights and avoidance of stigma. MHA use in this setting should be exercised with caution and by appropriately trained individuals. What is known about the topic? The MHA and its state and territory counterparts provide for the treatment, care and support of people who have a mental illness and the protection of a person’s rights therein. Despite not being intended for application in generalist facilities, mental health legislation is widely used in generalist facilities and certificates are completed by generalist health professionals with limited training in this area of practice. What does this paper add? This study adds to the limited body of knowledge in relation to MHA detention in acute generalist facilities. Disparate preparation of medical officers in the use of this legislation has been identified, which has potential wider implications for patients beyond immediate care. What are the implications for practitioners? Inadequate attention to correct completion of MHA certificates and associated documentation could potentially invalidate detention, leaving healthcare professionals and institutions open to litigious claims that restrictive or coercive practices subsequent to the certificate’s completion were technically unlawful. Further, detention under the MHA, albeit temporarily, has potential human rights issues attached and wrongful detention could lead to longstanding issues relating to stigma.

Objective. This study compares patterns of tobacco use during pregnancy over time and across population subgroups and examines the impact of maternal smoking on the incidence of low birth weight (LBW). The study also evaluates the use of birth certificates to monitor prenatal smoking. Methods. The birth certificates of all states (except California) and the District of Columbia for 2000 provided to Centers for Disease Control and Prevention’s National Center for Health Statistics were analyzed. Trends in maternal smoking were examined with data from birth certificates and other relevant sources. Results. Smoking during pregnancy was reported for 12.2% of women who gave birth in 2000, down 37% from 1989 (19.5%), when this information was first collected on birth certificates. Throughout the 1990s, prenatal smoking rates were highest for older teenagers and women in their early 20s. Among population subgroups, the highest rates were reported for non-Hispanic white women who attended but did not complete high school. The incidence of LBW among singleton infants who were born to smokers was double that for nonsmokers. This relationship was observed in all age groups, for births to Hispanic and non-Hispanic white and black women, and within educational attainment subgroups. Even light smoking (<5 cigarettes daily) was associated with elevated rates of LBW. Conclusion. Although prenatal smoking may be underreported on the birth certificate, the trends and variations in smoking based on birth certificate data have been confirmed with data from other sources. Birth certificate data can be useful in monitoring prenatal smoking patterns. Changes in the birth certificate questions that are to be implemented beginning in 2003 will help to clarify the levels and changes in smoking behavior during pregnancy so that smoking cessation programs can be more effectively designed to meet the needs of the populations at risk.

Abstract Background death certification data are routinely collected in most developed countries. Coded causes of death are a readily accessible source and have the potential advantage of providing complete follow-up, but with limitations. Objective to investigate the reliability of using death certificates for surveillance of dementia, the time trend of recording dementia on death certificates and predictive factors of recording of dementia. Subjects individuals aged 65 and over in six areas across England and Wales were randomly selected for the Medical Research Council Cognitive Function and Ageing Study (CFAS) and CFAS II with mortality follow-up. Methods prevalence of dementia recorded on death certificates were calculated by year. Reporting of dementia on death certificates compared with the study diagnosis of dementia, with sensitivity, specificity and Cohen’s κ were estimated. Multivariable logistic regression models explored the impact of potential factors on the reporting of dementia on the death certificate. Results the overall unadjusted prevalence of dementia on death certificates rose from 5.3% to 25.9% over the last 26 years. Dementia reported on death certificates was poor with sensitivity 21.0% in earlier cohort CFAS, but it had increased to 45.2% in CFAS II. Dementia was more likely to be recorded on death certificates in individuals with severe dementia, or those living in an institution, yet less likely reported if individuals died in hospital. Conclusion recording dementia on death certificate has improved significantly in the England and Wales. However, such information is still an underestimate and should be used alongside epidemiological estimations.

Full textAbstract:
In the first land registration, the phrase cadastral registration, a technical term for recording records, land registration, ownership of rights, rechkadastral, and legal cadastral, is governed by government regulation 10 of 1961. In occasional land registration, BPN does not employ competent administration, resulting in administrative flaws that might lead to duplicate certificates for land parcel owners. To obtain legal certainty over the physical and legal ownership of land parcels in the ownership of the certificate of title and to apply the muthakir principle, the ownership of the certificate is doubled because Bpn's registration does not use the most recent principle in sporadic land registration for the first time. This study employs normative juridical research, namely library law research or secondary data with primary, secondary, and tertiary legal sources, as well as interviews with district-city measurements. Land registration must have a foundation, namely a land book, so that the landowner's ownership has legal certainty that stays valid on the land's physical surface with a legal certificate of ownership, namely a certificate. The conclusion is that in the issuance of double certificates, legal remedies may be settled through non-litigation, mediation between the aggrieved party, the land owner, and the National Land Agency (Non Litigation), and if this is not possible, through court (litigation) peace and tax restitution.

Full textAbstract:
Background: The medical document certifying the cause of death provides vital data to develop health policies. In spite of very comprehensive guidelines issued by the WHO for thecompletion of death certificates; very few certificate arefound errorfree which might be due to lack of knowledge and practice on the part of physicians issuing that certificate.Purpose of this study is to assess the knowledge and competencies of a doctor in completing a death certificate. Methods: This study was cross-sectional. The population of this study was physicians of a tertiary care hospital of Lahore. A structured questionnaire along with a case scenario was given to 137 physicians having variable working experiences, performing in different clinical departments of a tertiary care hospital of Lahore.The participants were asked to complete the component of cause of death of the certificateonly. The percentage of omissions done by the doctors during the completion of said section was analyzed using the chi square test to establish the association between participant’s characteristics and their relevant responses. Results: Among 137participants working in different clinical departments of a Tertiary Care Hospital at Lahore, 89% were having less than 5 years’ experience and 11% having more than 5 years’ experience. 53% were qualified from public sector, 24% from private sector and 23% from foreign institutes. 77% doctors identified immediate cause of death incorrectly, 83 % did not identify and interpret underlying cause of death correctly; 90 % did notidentify contributory cause of death correctly. In46 % cases mechanism/mode of death was confused with the cause of death. Practical Implication: The correct completion of death certificates would provide an accurate and genuine mortality index essential for framing a national health policy. Conclusion: Physician’s knowledge and skill of completing the death certificates is very deficient and alarming which necessitate periodical and regular training of the physicians on completing the death certificates as per guidelines of the WHO to get an appropriate and valid health statistics effective for future public national health policies and strategies. Keywords (MeSH): Death certificate completion, Medical certification of cause of death, Physician’s knowledge, skill to complete death certificate, Mortality index

Full textAbstract:
Objectives. We inventoried and reviewed the birth and fetal death certificates of all 50 U.S. states to identify nonstandard data items that are environmentally relevant, inexpensive to collect, and might enhance environmental public health tracking. Methods. We obtained online or requested by mail or telephone the birth certificate and fetal death record forms or formats from each state. Every state data element was compared to the 2003 standards promulgated by the National Center for Health Statistics to identify any items that are not included on the standard. We then evaluated these items for their utility in environmentally related analyses. Results. We found three data fields of potential interest. First, although every state included residence of mother at time of delivery on the birth certificate, only four states collected information on how long the mother had lived there. This item may be useful in that it could be used to assess and reduce misclassification of environmental exposures among women during pregnancy. Second, we found that father's address was listed on the birth certificates of eight states. This data field may be useful for defining paternal environmental exposures, especially in cases where the parents do not live together. Third, parental occupation was listed on the birth certificates of 15 states and may be useful for defining parental workplace exposures. Our findings were similar for fetal death records. Conclusion. If these data elements are accurate and well-reported, their addition to birth, fetal death, and other health records may aid in environmental public health tracking.

Full textAbstract:
The information which Her Majesty's Government provides, usually in answer to an inquiry by the court, is given by a certificate which in terse formulations sets forth the Government's conclusions, but does not give reasons or explain the process which had led the Government to its conclusions. Correspondence which precedes the actual certificate and which may foreshadow its contents may throw light on the certificate, but is no substitute for it. A certificate once granted is binding or conclusive in the sense that no evidence gainsaying it is admissible. However, the certificate is also exclusive in the sense that, where facts of State have to be ascertained, the information requested from and given by the Executive is the only permitted source of establishing the facts. While the Executive's certificate is conclusive and exclusive on questions of fact only, it remains subject to legitimate interpretation by the judiciary.

Full textAbstract:
A green energy certificate transaction, as one of the ways to meet China’s renewable energy quota system, is a virtual transaction through the renewable energy trading system. Different from the market mechanism of only one transaction in the past audit cycle, this paper establishes an agent-based renewable energy system with multi-period trading according to the existing green energy certificate trading policy. With simulation of a period of audit of green spot multi-period transactions, the agent of limited rationality makes it in the pursuit of their utility under the premise of interaction. The experiment observes the utility level of agents under different trading strategies, verifies the influence of different policy behaviors on the market, and obtains the market equilibrium state. The conclusion shows that there is a serious green certificate premium in the early stage of the market. After adjustment by fines, the green certificate price of 0.05-0.08 yuan can maximize social welfare and stimulate the enthusiasm for individual purchases.

This brief conclusion looks at two final speech “acts” in Derrida and in the French language more generally: an acte de décès, literally a “death act,” typically translated into English as “death certificate,” and an acte de naissance, that is, a “birth certificate.” I conclude with these modalities of “speech act” because they both bring us to the place where, I argue, Derrida begins and ends his reflections on speech act theory, namely, to an act in writing that is always accomplished beyond the subjectivity, power, and life of the person for whom it is issued, an act (of birth or death) that determines the limits of the power that is presumed to reside in the subject, an act that has inscribed within it an ineffaceable reference to time, language, the other, and generations.

Tidal turbines are emerging technologies offering great potential for the harnessing of a renewable and predictable oceanic resource. However, exploitation at sea comes with significant design, installation, grid connection, and maintenance operations challenges. Consequently, guidelines and standards are required to ensure safety, quality, performance and accelerate tidal turbines development and commercialisation. Standardisation is also a necessity to support and improve safety and confidence of a wide range of Marine Renewable Energy (MRE) stakeholders such as designers, project operators, investors, insurers or final users. There are undergoing developments on guidelines, standards and certification systems within the International Electrotechnical Commission (IEC) Technical Committee TC 114 “Marine energy - Wave, tidal and other water current converters” and the IEC Renewable Energy “Marine Energy - Operational Management Committee” (IECRE ME – OMC). However, as the tidal energy concepts are only at the demonstration stage, only few guidelines and no dedicated certification scheme has been published so far within this organization, which guarantee an international, independent, non-governmental and consensus-based elaboration process. The aim of this paper is to present a proposal of certification methodology, developed by Bureau Veritas for the design assessment of current and tidal turbines, and its application to a French case study. This certification procedure was developed within the French research project Sabella D10 funded by ADEME and is published in the Bureau Veritas guideline NI603 “Current & Tidal Turbines”. The suggested certification procedure addresses prototype, component, type and project certification. Main objective, scope, intermediary steps to be completed and resulting certificates will be detailed for each certification scheme, as well as their interactions. This methodology will be illustrated by the case study on the Sabella D10 prototype, a French tidal turbine installed in 2015 in the Fromveur Passage, off Ushant Island. Sabella D10 is a 1 MW tidal turbine fully submerged laid on the seabed with a horizontal axis and 6 blades. It is the first French tidal turbine producing electricity and connected to the electrical network. The Sabella D10 case study will focus on prototype certification and computations performed for support structure and blades. The paper will describe the load cases that have been considered, the review procedure for the support structure and the blades design assessment, including description of a streamlined method for basic design and a detailed method for final design. In conclusion, the next steps will be introduced to continue the certification developments of tidal and current turbines.

Abstract The specific mission was to identify the conditions of atmospheric pressure and ambient temperature under which a so-called empty-Boeing model 747-131 fixed wing jet aircraft center wing tank (CWT), containing a residual fuel loading of about 3 kg/m3, less than 100 gallons of aviation kerosene (JetA Athens refinery commercial jet fuel), could form hazardous air/fuel mixtures. The issues are limited to explosion safety concerns relating to certificated fixed wing jet aircraft in regularly scheduled commercial passenger service. It is certain that a combustible mixture does not exist in a fuel tank containing Jet-A type fuel at ambient temperatures below 38°C (100°F), which is the lean limit flash point (LFP) for commercial jet fuel at sea level. Never the less, although not included in this paper, the original study reported by Wyczalek and Suh (1997), identified six highly unlikely, but rationally possible critical conditions which can occur in a combination which may permit a combustible mixture to exist within a jet aircraft fuel tank and pose a potential hazard. The scope of this paper is limited to mathematical modeling concerns related to fixed wing jet aircraft fuel tanks and commercial jet fuels combustible air-fuel mixture ratios. It was further limited to a historical review of the scientific literature in the public domain from 1950 to the present time, which defined the thermodynamic and minimum ignition energy properties of aviation gasoline and commercial jet fuels; and, to comparisons with new thermodynamic data for JetA Athens flight test samples, released by the National Transportation Safety Board (NTSB) during public hearings on the TWA800 event in Baltimore, Maryland in December 1997. The original work reported by Wyczalek and Suh (1997) conclusively demonstrated that the USAF Wright Air Development Center and the US Bureau of Mines conducted and published comprehensive evaluations of the potential hazards relating to jet aircraft fuel tanks as early as 1952. This historical scientific data and the mathematical models for the new jetA and Athens refinery jetA in this paper, are relevant to pending TWA800 related litigation, and to the future implementation of NTSB recommendations resulting from the TWA800 event.

Full textAbstract:
Due to environmental regulations, Oxides of nitrogen (NOx) and carbon monoxide (CO) are important issues for gas turbine plants. Regulators are becoming more and more involved and they often require overall and real-time emission information. These measurements can easily be done with gas analyzers. This technology is called CEMS: Continuous Emissions Monitoring System. With CEMS, regulators easily understand proofs such as calibration and certificate. However, this technology is expensive to buy and to maintain. An alternative method is to use a calculation based on the turbine operation. This technology is called PEMS: Predictive Emissions Monitoring System. Although PEMS is less expensive than CEMS, setting up and managing a PEMS mathematical formula to fully respond to the expectations of the regulator is more complicated than using CEMS. This paper describes an approach to set up an equation for PEMS which can be accepted by regulators. Before starting PEMS research, expectations must be established. What are the expectations of the regulator? What are the users’ expectations? Yes, do not forget the goals of the unit operators. It is not sufficient to provide answers for regulator at the lowest cost. A responsible user is also concerned about the environmental aspect and this fact will help your in the future. GRTgaz, the main gas transmission company in France managing 44 turbines spread over 25 stations across France, has decided to answer these questions before starting research. The answers to these questions make up the first part of this 4-part paper. The second part of the paper is a review of publications and literature. Since no applicable PEMS exist for all types of combustion turbines, analyzing empirical and theoretical formulas leads to the important parameters and the link between them. The third part is dedicated to turbines. A lean premixed combustion system and its regulation are described. Also in this part, the available measured parameters are listed in regards to their combustion influence and their accuracy. The fourth part deals with the establishment of equations and their tests in regards to the goals. The last part presents the implementation of the equations on the units. If tools and knowledge are available, the conclusion point out that achieving a PEMS requires a good evaluation and understanding of the expectations of the regulator, not only in the present day but also what they will and could be.
