The relationship between unsafe working conditions and workers' behavior and their impacts on injury severity in the U.S. construction industry

Unsafe acts of workers (e.g. misjudgment, inappropriate operation) become the major root causes of construction accidents when they are combined with unsafe working conditions (e.g. working surface conditions, weather) on a construction site. The overarching goal of the research presented in this paper is to explore ways to prevent unsafe acts of workers and reduce the likelihood of construction accidents occurring. The study specifically aims to (1) understand the relationships between human behavior related and working condition related risk factors, (2) identify the significant behavior and condition factors and their impacts on accident types (e.g. struck by/against, caught in/between, falling, shock, inhalation/ingestion/absorption, respiratory failure) and injury severity (e.g. fatality, hospitalized, non-hospitalized), and (3) analyze the fundamental accident-injury relationship on how each accident type contributes to the injury severity. The study reviewed 9,358 accidents which occurred in the U.S. construction industry between 2002 and 2011. The large number of accident samples supported reliable statistical analyses. The analysis identified a total of 17 significant correlations between behavior and condition factors and distinguished key risk factors that highly impacted on the determination of accident types and injury severity. The research outcomes will assist safety managers to control specific unsafe acts of workers by eliminating the associated unsafe working conditions and vice versa. They also can prioritize risk factors and pay more attention to controlling them in order to achieve a safer working environment.
Graduate-entry medicine

A small number of universities offer a shorter, more focused course in medicine for those holding a previous degree. This chapter discusses the pitfalls and promise of studying medicine as an older, more experienced, and academically certain candidate. It covers the differing academic requirements across the available universities, as well as their requested entrance exams and any unique desirables for each specific course. The chapter also offers advice on the types of work experience and uses to which undergraduate time should be put in order to maximize the chances of success when applying for graduate-entry medicine.
Fuzzy logic model analysis of shear force in aluminium / polyethylene lap joined by hot press

Fuzzy logic is an optimization technique used to predict the behaviour of any problem. Polyethylene (PE) sheet of thickness 3 mm was joined by means of hot press method with aluminium (Al) of thickness 1mm using lap join type. The inside surface of aluminium in the lap joint region was anodized to increase the size of surface pores and mechanical interlock between the melted polymers in the pores of anodized surface of aluminium. The anodizing process was performed by a solution of 15%wt. sulphuric acid with deionized water. The anodizing current density and time were 200A/m2 and 60 min. respectively. The hot press process parameters were; temperature: 115, 125, 135 and 145 °C, pressure: 2, 4, 6, and 8 bar and the pressing time: 1, 2, 3 and 4 min. The hot press method was successfully joined the anodized Al with PE sheet. Shear tensile test was used to estimate the shear strength of lap join. These data are optimized using a fuzzy logic concept which gives a good indication about the effect of input process parameters on the shear of joints. Increasing the applied pressure, decreasing the pressing time and increasing the temperature up to 80 °C resulted in increasing the maximum shear force of joint.
A Heuristic Branch-and-Price Approach for the Airline Crew Pairing Problem

We describe a methodology for nding near-optimal solutions to airline crew pairing problems. We use a dynamic column generation scheme to identify crew work schedules combined with a customized branch-and-bound procedure that allows column generation to be performed at each node of the search tree. Our approach provides an approximation to optimality since we only solve the column generation subproblems approximately and we do not necessarily consider all of the unexplored nodes in the search. We present computational results for both a research implementation and a production implementation of the algorithm on test problems from a major domestic carrier. We test the innuence of various algorithmic design choices with the research implementation. These results were used to build a production implementation capable of nding good solutions to problem instances with over 2000 ight legs.
Historical and Contemporary Perspectives on Migration

In the opening sentence of the preface to the first edition of his classic, A History of Experimental Psychology , Edwin G. Boring ( 1929 ) reminded readers that “ psychology has a long past, but only a short history ” (p. ix), a remark he attributed to the pioneer of memory research, Hermann Ebbinghaus. A similar statement may be made about the study of adolescents and their development. The first use of the term adolescence appeared in the fifteenth century. The term was a derivative of the Latin word adolescere , which means to grow up or to grow into maturity (Muuss, 1990 ). However, more than 1,500 years before this first explicit use of the term adolescence, both Plato and Aristotle proposed sequential demarcations of the life span, and Aristotle in particular proposed stages of life that are not dissimilar from sequences that might be included in contemporary models of youth development. He described three successive, seven year periods (infancy, boyhood, and young manhood) prior to the full, adult maturity. About 2,000 years elapsed between these initial philosophical discussions of adolescence and the emergence within the twentieth century of the scientific study of this period of life (with the publication in 1904 of G. Stanley Hall ’ s two volume work on adolescence). Across the subsequent (at this writing) 106 years, the history of the scientific study of adolescence has had three overlapping phases (Steinberg & Lerner, 2004 ). These phases in the history of the field, which we discuss in the pages that follow, are illustrated in Figure 1.1 .
A UML Profile for Risk-Driven Development

A profile for Risk-Driven Development (RDD) is presented. The profile described has been used in the Aspect- Oriented Risk Driven Development (AORDD) framework to annotate structural and behavioral UML models of security mechanisms. These annotations have been extracted for use in the trade-off analysis tool of the AORDD framework. The profile consists of stereotypes and tags that annotate UML class, deployment, and sequence diagrams. Extensions to annotate other behavioral diagrams will be added.
Wymagania na rozdzielczość i nieliniowość przetwornika C/A dla sygnału OFDM

Przetworniki cyfrowo-analogowe (C/A) są obecnie jednymi z niezbednych elementow kazdego radiowego urządzenia nadawczego [1]. Przykladem ich zastosowania jest typowa konstrukcja nadajnika radiowego z modulacją kwadraturową, ktorej uproszczony schemat jest przedstawiony na rys. 1. Uklady przetwornikow C/A stanowią interfejs miedzy cześcią cyfrową, w ktorej generowane są dane do transmisji, a cześcią analogową, w ktorej nastepuje przemiana czestotliwości i wzmocnienie sygnalu. Dlatego bardzo istotny jest wybor przetwornika o odpowiednio dobrych parametrach, zapewniającego poprawne przetwarzanie i utrzymującego zalozoną jakośc sygnalu. Zagadnienie to jest szczegolnie istotne w przypadku stosowania modulacji OFDM – Orthogonal Frequency Division Multiplexing (modulacji na wielu ortogonalnych podnośnych), ktora sprawia, ze przebieg czasowy przesylanego sygnalu staje sie bardzo skomplikowany.
Interference management in cognitive radio systems

Currently, the radio spectrum is beginning to be crowded due to the rapid growth of wireless technologies this century. However, many studies show that the major licensed bands, such as those allocated for television broadcasting, amateur radio, paging, etc. are underutilized and some of the remaining bands are heavily used. This fact leads to spectrum wastage. Therefore, new techniques are needed to take advantage of the spectrum opportunities causing a reasonable level of interference in the licensed bands. Hence, cognitive radio has become an important research topic in these last years since it tries to take advantage of the unused spectrum by the licensed users. In addition to spectrum sensing algorithms, sharing protocols, policies, among other things, the interference management has become an important topic in cognitive radio in order to manage and fulfil the regulatory constraints. The management of interference is, unquestionably, required to treat and quantify all the interference produced by the unlicensed users at the licensed receivers. In order to manage this interference, the secondary users must be able to adjust their parameters to fulfil these constraints. In the current work is presented an overview of cognitive radio and interference management. Several quantitative and performance criteria are studied as well, in order to illustrate the effect that the different parameters produce on the interference in the licensed bands.

There was an increasing of microbial population in line with the increasing of slurry dosage.P2 contained the highest population of bacteria or fungal (F <0.05) compared to P0 or P1.
Measurement report: Introduction to the HyICE-2018 campaign for measurements of ice nucleating particles in the Hyytiälä boreal forest

Abstract. The formation of ice particles in Earth’s atmosphere strongly influences the dynamics and optical properties of clouds and their impacts on the climate system. Ice formation in clouds is often triggered heterogeneously by ice nucleating particles (INPs) that represent a very low number of particles in the atmosphere. To date, many sources of INPs, such as mineral and soil dust, have been investigated and identified in the lower latitudes. Although less is known about the sources of ice nucleation at higher latitudes, efforts have been made to identify the sources of INPs in the Arctic and boreal environments. In this study, we investigate the INP emission potential from high latitude boreal forests. We introduce the HyICE-2018 measurement campaign conducted in the boreal forest of Hyytiälä, Finland between February and June 2018. The campaign utilized the infrastructure of the SMEAR II research station with additional instrumentation for measuring INPs to quantify the concentrations and sources of INPs in the boreal environment. In this contribution, we describe the measurement infrastructure and operating procedures during HyICE-2018 and we report results from specific time periods where INP instruments were run in parallel for inter-comparison purposes. Our results show that the suite of instruments deployed during HyICE-2018 reports consistent results and therefore lays the foundation for forthcoming results to be considered holistically. In addition, we compare the INP concentration we measured to INP parameterizations, and we show a very good agreement with the Tobo et al. (2013) parameterization developed from measurements conducted in a ponderosa pine forest ecosystem in Colorado, USA.
AIRPORT PAVEMENT EVALUATION AND ACN-PCN CLASSIFICATION . THIRD INTERNATIONAL CONFERENCE ON BEARING CAPACITY OF ROADS AND AIRFIELDS. PROCEEDINGS, NORWEGIAN INSTITUTE OF TECHNOLOGY, TRONDHEIM, NORWAY, JULY 3-5 1990. VOLUMES 1-2

This paper describes The Laboratorio Nacional de Engenharia Civil's experience on airport pavement bearing capacity evaluation and ACN-PCN (aircraft classification number-pavement classification number) classification, using the structural analysis approach. Use is made of Falling Weight Deflectometer test results in combination with elastic layer computer programs such as BISAR or ELSYM 5. Studies were performed on different types of airport pavements: national airports in Portugal, as well as airports with very low traffic volumes like one airport in Africa and several local airports in Portugal. One of the main conclusions drawn from these studies is that the ACN-PCN system for bearing capacity classification has some drawbacks for airports designed for low traffic volumes, since values of PCN lower than the ACN of the aircraft using the pavements can be obtained, although the remaining life of such pavements is enough to sustain the forecast number of movements of those aircraft during the pavement's design life.

Bioprinting for constructing microvascular systems for organs

Abstract: Regenerative medicine/tissue engineering (TE) has emerged as a potential solution to overcome the current shortage of organs/tissue for transplantation. However, generating microvascularized tissue still challenges TE for the creation of suitable organs. In addressing this, numerous approaches over the last decade culminated in one main strategy emerging: bioprinting. The combination of medical imaging, bio-computer aided design (bio-CAD) systems, and modern fabrication approaches promises to overcome the current limitations in constructing organs with microvascular systems. Specifically, appropriate bioprinting strategies have been proposed to fabricate biomimetic organs/tissue microvasculature. Bioreactor systems have been incorporated into bioprinting to enhance maturation of the bioprinted organ/tissue. Despite important advances in microvascular bioprinting, further work is required to enhance the interface of medical imaging and bio-CAD, optimize bioprinting systems, and accelerate the maturation process of bioprinted implants.
Do Strict Environmental Regulations in the OECD Discourage Foreign Firms? - Le imprese straniere sono scoraggiate dal rigore della legislazione ambientale nei paesi OCSE?

The study forms a relationship between the perceived stringency of environmental policy and the location decision of firms. We use data from 3,785 firms operating in 7 OECD countries to show that strict environmental regulation in the OECD may not necessarily discourage foreign firms. Rather, foreign owned firms perceive environmental regulations in the OECD as stricter when comparing to other non-OECD markets in which they operate in. We also find that firms who have foreign headquarters are relatively newer, are listed on a stock exchange and tend to have a better business performance. - Questo studio esamina la relazione esistente tra il rigore delle politiche ambientali – percepito dalle imprese – e le decisioni di localizzazione delle imprese. I dati utilizzati si riferiscono a 3785 imprese in 7 paesi OCSE e mostrano come una legislazione ambientale severa in quest’area non necessariamente scoraggia le imprese straniere. Piuttosto, le societa a capitale estero percepiscono le leggi ambientali nell’area OCSE come maggiormente restrittive rispetto a quelle di altri paesi dell’area non-OCSE nei quali esse gia operano. Viene inoltre trovata evidenza che societa aventi sede all’estero sono relativamente piu giovani, sono quotate in borsa e tendono ad avere migliori performance economiche.
Monografies de la Institució Catalana d’Història Natural Biodiversity in anthropized marinas The case of the Barcelona Forum bathing area (Spain)

The Mediterranean Sea is a hotspot for biodiversity and endemic species (between 4 % and 18 % of known species are endemic, depending on the group), but this environment, favourable for native species, also favours exotic species. To ascertain how biodiversity has been impacted by intense human activity, we surveyed the marine life in the Barcelona Forum bathing area, an artificial beach receiving large amounts of waste from neighbouring areas and effluent from the nearby sewage treatment plant. Despite such eutrophic influences and the replacement of natural substrates with artificial ones, a surprisingly rich marine biota of 514 species was found. The groups with most species identified were molluscs (176), fish (88), crustaceans (65) and algae (50). These results include 15 exotic species that have settled in this ecosystem, such as the sea hare Bursatella leachii and the polychaete Branchiomma luctuosum, and some iconic natives such as the Fan mussel (Pinna nobilis) and the Dusky grouper (Epinephelus marginatus). Urban litter was sampled and no significant deleterious effects on the biota were detected. The site acts as a refuge for fish and is conducive to the settlement of encrusting species that colonize new substrates.
MIM's the Word - Capacitors for Fun and Profit

Capacitor properties were studied using a special test mask. We derived improved measurement and test capacitor and cell design. We saw a small perimeter scaling as well as the usual area scaling. Time dependent dielectric breakdown was extensively studied. We determined that the 4V/sec breakdown voltage is a sound figure of merit for that, and that nitride deposition conditions can be tuned for better TDDB performance, important for medium voltage applications. Capacitor nitrides as thin as 25 nm were seen to be feasible.
ECONOMIC ANALYSIS OF A GRID CONNECTED SOLAR HYDROGEN PV SYSTEM

The grid connected solar hydrogen energy system has been developed in order to investigate the performance under the local climate conditions. The grid connected solar hydrogen energy system (GCSHES) have the capability of overcoming the problems that occur on the grid connected power system (GCPS) when there is a black-out of grid electricity. Moreover, stand alone power system (SAPS) requires batteries, and larger hydrogen tank capacity is required for higher energy generation. An experimental GCSHES has been setup and tested. The GCSHES consists of subsystems photovoltaic (PV) array with 40 PV module with its capacity of 5000 Wp, inverter capacity (6000W), electrolyzer, hydrogen tank and fuel cell (500 W). The monthly efficiency and performance of PV array is 12.7% and 26%, while the efficiency and performance of inverter is 95.1% and 98%, respectively. The techno-economical analysis indicated that the pay back period of this system is 18 years.

Imaginal exposure for chronic worry : the role of anxious arousal and imaginal sensory information

This study examined the effect of exposure script references to anxious physiological sensations and the five senses upon anxious arousal during a single 30-minute imaginal exposure. Forty-five high worriers were randomized to two conditions: Comprehensive (all reference types included) or Limited (only visual and auditory references included). Anxious arousal was measured via heart rate (HR), skin conductance level (SCL) and self-report. Both conditions exhibited increased arousal patterns from baseline. SCL did not significantly decrease in either condition during exposure. For self-reported anxiety, Comprehensive participants exhibited significant decreases throughout exposure; but Limited participants demonstrated significant increases. Comprehensive participants reported significantly greater anticipated ability to cope after exposure. Results are discussed in the context of emotional processing theory.
Recording automotive crash event data

The National Transportation Safety Board has recommended that automobile manufacturers and the National Highway Traffic Safety Administration work cooperatively to gather information on automotive crashes using on-board collision sensing and recording devices. Since 1974, General Motors' (GM) airbag equipped production vehicles have recorded airbag status and crash severity data for impacts that caused a deployment. Many of these systems also recorded data during “near-deployment” events, i.e., impacts that are not severe enough to deploy the airbag(s). GM design engineers have used this information to improve the performance of airbag sensing systems and NHTSA researchers have used it to help understand the field performance of alternative airbag system designs. Beginning with the 1999 model year, the capability to record pre-crash vehicle speed, engine RPM, throttle position, and brake switch on/off status has been added to some GM vehicles. This paper discusses the evolution and contents of the current GM event data recording capability, how other researchers working to develop a safer highway transportation system might acquire and utilize the information, and the status of the NHTSA Motor Vehicle Safety Research Advisory Committee’s Event Data Recorder Working Group effort to develop a uniform approach to recording such data.
