Capacidad Estatal y Vulnerabilidad ante el Riesgo de Desastres: El caso del Megaincendio de 2014 en Valparaíso, Chile
Authors: Rivas Ricardo , Maldonado Luis , Campos Katherine , Ojeda Lautaro 
Published: July 2024

Una de las principales contribuciones de las ciencias sociales al estudio de los desastres socionaturales ha sido la exploración del concepto de vulnerabilidad. Sin embargo, la literatura sobre desastres ha considerado a la vulnerabilidad como una característica endógena de individuos o comunidades, dándole poca importancia a factores sociales que enmarcan la acción de los agentes. El presente estudio pone el foco en el entorno institucional a través del concepto de Capacidad Estatal e indaga en la asociación entre ésta y la vulnerabilidad en contextos de desastres. Para ello, estudiamos el caso del megaincendio que afectó a la ciudad de Valparaíso el año 2014 sobre la base del análisis de documentos y entrevistas semiestructuradas a actores asociados con la gestión del riesgo de desastre (GRD) bajo estudio. Los resultados sugieren que las limitaciones de la capacidad estatal en Chile agravan la vulnerabilidad de las comunidades, en tanto la GRD ha estado determinada por una mirada coyuntural de los distintos gobiernos de turno que no ha permitido desarrollar capacidades estatales de largo plazo para la GRD. Considerando estos resultados, presentamos conclusiones sobre la relevancia de la ‘continuidad institucional’ en relación al desarrollo de dichas capacidades estatales.

The influence of leverage on accrual-based and real earnings management: Evidence from the UK
Authors: Al-Shattarat Basiem 
Published: July 2024

The crucial aim of this study is to observe the association between leverage and earnings management using accrual-based earnings management (AEM) and real earnings management (REM) practices among the firms listed on the London Stock Exchange. To keep unobservable elements under control, this study employs a Two-Stage Least Squares approach to analyse data from UK-listed firms for the years 2009-2020. The findings reveal that there is a significant negative association between leverage and earnings management through REM but not through AEM. The results are aligned with the premise that leverage works towards limiting REM activities, which eventually influences the accounting earnings quality. Therefore, high leverage calls for debt repayment to minimise the available cash for management’s non-optimal spending, depending on the lender-induced spending limitations. Further, this is predicted to minimise managers’ opportunistic behaviours and encourage their conservativeness. The study findings have implications for the regulatory and stock market players as it provides in-depth information concerning current practices in accounting and reporting.
El objetivo crucial de este estudio es observar la asociación entre el apalancamiento y la gestión de beneficios mediante prácticas de gestión de beneficios basadas en el devengo (AEM) y gestión de beneficios reales (REM) entre las empresas que cotizan en la Bolsa de Londres. Para mantener bajo control los elementos no observables, este estudio emplea un enfoque de mínimos cuadrados en dos etapas para analizar los datos de las empresas que cotizan en el Reino Unido durante los años 2009-2020. Los resultados revelan que existe una asociación negativa significativa entre el apalancamiento y la gestión de beneficios a través de REM, pero no a través de AEM. Los resultados concuerdan con la premisa de que el apalancamiento contribuye a limitar las actividades de REM, lo que a la larga influye en la calidad de los beneficios contables. Por lo tanto, un apalancamiento elevado exige el reembolso de la deuda para minimizar el efectivo disponible para gastos no óptimos de la dirección, en función de las limitaciones de gasto inducidas por el prestamista. Además, se predice que esto minimiza los comportamientos oportunistas de los directivos y fomenta su conservadurismo. Las conclusiones del estudio tienen implicaciones para los agentes reguladores y bursátiles, ya que proporciona información en profundidad sobre las prácticas actuales en materia de contabilidad y presentación de informes.
PLASMA PARAMETRS AND SILICON ETCHING KINETICS IN CF4 + C4F8 + O2 MIXTURE: EFFECT OF CF4/C4F8 MIXING RATIO
Authors: Efremov Alexander M. , Bobylev Alexander V. , Kwon Kwang-Ho 
Published: July 2024

In this work, we investigated the influence of fluorocarbon component ratio in the CF4 + C4F8 + O2 gas mixture on electro-physical plasma parameters, steady-state densities of active species and silicon etching kinetics under typical reactive-ion process conditions. The combination of plasma diagnostics (double Langmuir probes, optical emission spectroscopy) and plasma modeling confirmed known peculiarities of plasma chemistry of individual fluorocarbons in the presence of oxygen as well as provided an extended analysis of both fluorine and oxygen atom kinetics in the three-component gas mixture. It was shown that the substitution of CF4 by C4F8 at the constant fraction of O2 a) causes the weak disturbance in electrons- and ions-related plasma parameters (electron temperature, electron density, ion energy flux); b) provides drastically increasing density of polymerizing CFx (x = 1, 2) radicals; and c) results in monotonically decreasing F atoms density. The latter is due to simultaneous changes in both F atom formation rate and their loss frequency, especially in C4F8-rich plasmas. From experiments, it was found that Si etching rate is by more than 85% controlled by its chemical component (in a form of ion-stimulated heterogeneous reaction Si + xF → SiFx) and decreases with increasing C4F8 fraction in a feed gas. The change in effective reaction probability contradicts with the growth of polymer deposition rate and film thickness (as it follows from changes in gas-phase plasma characteristics) but may reflect the weakening of surface passivation by oxygen atoms.

Sjælden type subaraknoidal blødning som årsag til svære rygsmerter
Authors: Metzler Emma Katrine , Richall Humeira , Simony Ane 
Published: July 2024

Introduktion og formål: Akut indsættende lænderygsmerter er en hyppig årsag til skadestuekontakt, ofte på grund af lumbago, mistanke om diskusprolaps eller mere akutte tilstande som for eksempel aortadissektion. Denne case viser en sjælden differentialdiagnose til svære lænderygsmerter: en spinal subaraknoidal blødning.
Metoder: Efter patientsamtykket er der indhentet information fra patientens journal om indlæggelser og efterfølgende ambulante besøg, samt information om medicinindtag og billeddiagnostiske fund.
Resultater: Casen drejer sig om en kvinde i magnylbehandling, der kommer ind som akut kald pga. svære rygsmerter, hvor aortadissektion udelukkes ved helkrops CT-skanning. Patienten undersøges grundigt og udskrives med diagnosen lumbago. Dagen efter kommer patienten igen på skadestuen med svære rygsmerter på trods af den opstartede smertestillende behandling og nytilkommet anal dysæstesi. Hun har ikke symptomer på cauda equina syndrom. Fire dage senere diagnosticeres hun med en spinal subaraknoidal blødning på MR af columna lumbalis.
Diskussion og konklusion: Da spinale subaraknoidale blødninger udgør <1 % af alle subaraknoidale blødninger, bør denne tilstand overvejes differentialdiagnostisk, efter en patient indlægges i en akutmodtagelse med svære rygsmerter, når hyperakutte tilstande, såsom aortadissektion, er udelukket. Tilstanden bør især overvejes, hvis patienten udviser neurologiske symptomer og smerter, der er svære at behandle. Hvis denne tilstand overses, kan det resultere i permanente neurologiske udfald eller død.
Facilitating Accuracy in Showup Identification Procedures: The Effects of the Presence of Stolen Property
Authors: Smith Andrew M. , Leach Amy‐May , Cutler Brian L. 
Published: December 2012

SummaryLaw enforcement personnel regularly present suspects to eyewitnesses using showups. In this study, we examined the impact of the presence of stolen property on live showup identification performance. Two hundred seventy university students were exposed to a simulated theft. During the subsequent showup, we manipulated the presence of the target and stolen property. Binary logistic regression analyses indicated that both factors independently predicted the accuracy of identification decisions. Participants were more accurate when the target was in the showup and when the stolen property was present during the identification. Consistent with the item, context, and ensemble theory of recognition, the presence of stolen property led to an increase in sensitivity, suggesting ensemble formation. Future research on showups should continue to examine contextual variables that may lead to changes in sensitivity or criterion shift. Copyright © 2012 John Wiley & Sons, Ltd.

Published: December 2012

ObjectiveThe aim of this study was to investigate whether a new cognitive–behavioral self‐help program with minimal coaching could improve psychological well‐being (depression, anxiety, and coping self‐efficacy) in people with rheumatic disease and depressive symptoms.MethodsIn total, 82 persons with a rheumatic disease enrolled in a randomized controlled trial were allocated to either a group receiving the self‐help program or a waiting list control condition group. For both groups, measurements were done at baseline, posttest, and followup. The outcome measures were the depression and anxiety scales of the Hospital Anxiety and Depression Scale and an adaptation of the Generalized Self‐Efficacy Scale. Repeated‐measures analyses of covariance were performed to evaluate changes in outcome measures from pretest to posttest and from posttest to followup.ResultsThe results showed that the self‐help program was effective in reducing symptoms of depression and anxiety and in strengthening coping self‐efficacy. The positive effects remained after a followup period of 2 months.ConclusionThis cost‐effective program could very well be used as a first step in a stepped care approach or as one of the treatment possibilities in a matched care approach.

ObjectiveWe tested the hypothesis that initiation of tumor necrosis factor α (TNFα) antagonists reduced the risk of fractures compared to nonbiologic comparators in patients with autoimmune diseases.MethodsUsing 4 large administrative databases, we assembled retrospective cohorts of patients with autoimmune diseases who initiated either a TNFα antagonist or a nonbiologic medication. We identified 3 mutually exclusive disease groups: rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and a combined group: psoriasis (PsO), psoriatic arthritis (PsA), or ankylosing spondylitis (AS). We used baseline covariate data to calculate propensity scores (PS) for each disease group and used Cox regression to calculate hazard ratios (HRs) and 95% confidence intervals (95% CIs). We compared the risk of combined hip, radius/ulna, humerus, or pelvic fractures between PS‐matched cohorts of new users of TNFα antagonists and nonbiologic comparators.ResultsWe identified 9,020, 2,014, and 2,663 new PS‐matched episodes of TNFα antagonist and nonbiologic comparator use in RA, IBD, and PsO‐PsA‐AS cohorts, respectively. The risk of combined fractures was similar between new users of TNFα antagonists and nonbiologic comparators for each disease (HR 1.17, 95% CI 0.91–1.51; HR 1.49, 95% CI 0.72–3.11; and HR 0.92, 95% CI 0.47–1.82 for RA, IBD, and PsO‐PsA‐AS, respectively). In RA, the risk of combined fractures was associated with an average daily dosage of prednisone equivalents >10 mg/day at baseline compared with no glucocorticoid (HR 1.54, 95% CI 1.03–2.30).ConclusionThe risk of fractures did not differ between initiators of a biologic agent and a nonbiologic comparator for any disease studied. Among RA patients, use of >10 mg/day of prednisone equivalents at baseline increased the fracture risk.
High‐Performance Red, Green, and Blue Electroluminescent Devices Based on Blue Emitters with Small Singlet–Triplet Splitting and Ambipolar Transport Property

Published: December 2012

AbstractTwo coordination complex emitters as well as host materials Be(PPI)2 and Zn(PPI)2 (PPI = 2‐(1‐phenyl‐1H‐phenanthro[9,10‐d]imidazol‐2‐yl)phenol) are designed, synthesized, and characterized. The incorporation of the metal atom leads to a twisted conformation and rigid molecular structure, which improve the thermal stability of Be(PPI)2 and Zn(PPI)2 with high Td and Tg at around 475 and 217 °C, respectively. The introduction of the electron‐donating phenol group results in the emission color shifting to the deep‐blue region and the emission maximum appears at around 429 nm. This molecular design strategy ensures that the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) HOMO and LUMO of Be(PPI)2 and Zn(PPI)2 localize on the different moieties of the molecules. Therefore, the two complexes have an ambipolar transport property and a small singlet–triplet splitting of 0.35 eV for Be(PPI)2 and 0.21 eV for Zn(PPI)2. An undoped deep‐blue fluorescent organic light‐emitting device (OLED) that uses Be(PPI)2 as emitter exhibits a maximum power efficiency of 2.5 lm W−1 with the CIE coordinates of (0.15, 0.09), which are very close to the National Television Standards Committee (NTSC) blue standard (CIE: 0.14, 0.08). Green and red phosphorescent OLEDs (PhOLEDs) that use Be(PPI)2 and Zn(PPI)2 as host materials show high performance. Highest power efficiencies of 67.5 lm W−1 for green PhOLEDs and 21.7 lm W−1 for red PhOLEDs are achieved. In addition, the Be(PPI)2‐based devices show low‐efficiency roll‐off behavior, which is attributed to the more balanced carrier‐transport property of Be(PPI)2.
Democratic Costs in Member‐Controlled Organizations
Authors: Pozzobon Daniela Maria , Zylbersztajn Decio 
Published: December 2012

ABSTRACTIn this study, we examine the costs of democratic control, an important factor affecting the competitiveness of traditional agricultural cooperatives. Although there has been some theoretical discussion about this issue, no empirical research has been done on these costs; the present study aims to bridge this gap. Following the literature, the main source of democratic costs in agricultural cooperatives is the level of member participation in cooperative governance. We have developed more specific theoretical insights about this special kind of decision‐making cost by showing the effect of differences in the level of member participation on democratic costs, differences in terms of democratic and influence costs and in terms of agency costs, and differences between both direct and opportunity democratic costs. Members should take both the relative direct and opportunity costs within total democratic costs into account when determining the optimal size and composition of their board.

Farmers’ Perceived Transaction Costs in Relation to Slaughterhouses of Different Ownership Structure
Authors: Hess Sebastian , Lind Lena W. , Liang Se 
Published: December 2012

ABSTRACTThe raison‐d’être of traditional cooperatives is claimed to be their capacity to reduce farmers’ transaction costs. Hence, one would expect transaction costs to increase when a traditional cooperative is transformed into a hybrid cooperative. The present study investigates this hypothesis. The empirical data originates from a survey with suppliers of Swedish Meats, a cooperative that used to dominate the Swedish meat sector. However, it lost the cooperative elements as external investors got a share of the ownership in 2007. Results indicate that the importance of typical drivers of perceived transaction costs are not homogeneously distributed. A subgroup of respondents still considers the former cooperative as a safe and trustworthy partner with reliable market information. Successful, entrepreneurial farmers instead perceive higher transaction costs when dealing with the hybrid cooperative. Geographical location and neighboring networks are insignificant. In general, the results confirm that the hybrid cooperative has lost its role as a cooperative.
Control Rights, Governance, and the Costs of Ownership in Agricultural Cooperatives
Authors: Chaddad Fabio , Iliopoulos Constantine 
Published: December 2012

ABSTRACTAgricultural cooperatives have changed considerably in recent decades. In witnessing these structural changes, scholars have proffered analyses of nontraditional ownership models focusing on residual claim rights. However, crucial information on the allocation of control rights in cooperatives is missing. This study sheds light on alternative ownership‐control models adopted by agricultural cooperatives in different regions across the world. In each of these models, we describe the allocation of formal control rights with a focus on decision management and decision control rights. We thus provide empirical evidence on the “separation of ownership and control” in agricultural cooperatives. We also analyze each of the governance models in terms of the associated ownership costs, including risk‐bearing costs, the costs of controlling managers, and collective decision‐making costs. In doing so, we are able to better understand the forces influencing the organizational efficiency of each cooperative model.
