IntroductionThe Strengths and Difficulties Questionnaire (SDQ) is a widely used assessment tool for measuring the psychological well-being of children and adolescents. It consists of 25 items that assess emotional symptoms, conduct problems, hyperactivity/inattention, peer relationship difficulties, and prosocial behavior.ObjectivesThe present study aimed to investigate the relationship between parental perceptions of difficulties and the results obtained from the SDQ.MethodsParticipants were recruited from the initial consultation of Child and Adolescent Psychiatry (N=132). Parents completed a questionnaire assessing their subjective perceptions of their child’s difficulties in various domains (home, school, learning activities, relations with friends) on a 4-point scale ranging from “no notion of difficulties” to “very severe difficulties”. They also completed the SDQ scale. Data were analyzed using SPSS software.ResultsIn this study, 74% of participants had scores on the SDQ indicating potential psychological difficulties. Additionally, 17.4% of participants had scores on the borderline between normal and abnormal results. 47% of patients scored above the cut-line for problems on the hyperactivity/inattention subscale, indicating higher levels of difficulties in this area. Conversely, only 3% of participants scored problematic scores on the peer relationship difficulties subscale. There was no statistical difference between sexes in terms of SDQ scores. A correlation analysis revealed a significant positive correlation (p < 0.01) between parental perceptions of difficulties and higher SDQ scores and the mean score on the SDQ scale was found to be significantly higher in patients who were rescheduled for another consultation following the evaluation by doctors, compared to those patients who received clinical discharge from the initial consultation (p-value 0,040).ConclusionsThis study provides valuable insights into the concordance between parental perceptions and objective assessments of difficulties in children and adolescents. Parents who perceived their child to have more difficulties also reported higher levels of psychological difficulties on the SDQ. This study highlights the importance of using tools like the SDQ to assess psychological well-being in children and adolescents. It also emphasizes the practical utility of the SDQ as a time-efficient assessment tool for use during initial consultations in child and adolescent psychiatry.Disclosure of InterestNone Declared

Very heavy stratiform precipitation (&amp;gt; 200 mm/per day) occurred in the Hokitika region on the west coast of the South Island of New Zealand on 18 June 2015, under north-westerlies with small CAPE (&amp;lt; 25 J/kg). Analyses of model simulations and observations showed that this heavy rainfall was due to cold front lifting enhanced by orographic lifting over the Southern Alps. At 1.5 km grid-length, the model terrain underestimated the average height of the 103 tallest mountains over the South Island by ~ 800 m. This leads to weaker orographic lifting and mountain blocking, and a faster-moving and stronger cold front in the Hokitika region. As a result, large errors in the heavy rainfall prediction occur. By increasing either the resolved or the sub-grid mountain heights, the simulated rainfall errors were largely reduced through stronger orographic lifting and mountain blocking, and a better simulation of the cold front movement and strength. All the experiments have the same “flow-over” regime with mountain waves and/or wave breaking (Fm ranges 0.61 – 1.21). However, the rainfall amount and distribution on the windward side of mountains altered significantly. Our new findings were that the Southern Alps can have significant indirect effects on heavy rainfall by altering the speed and strength of the cold front, in addition to the well-known direct dynamical effects (i.e., orographic lifting and mountain blocking). A combination of these direct and indirect effects makes the heavy rainfall simulation sensitive to mountain heights even under the same “flow-over” regime.

All organizations are subject to risk and uncertainty. Adverse events may disrupt normal organizational activity and may even cause complete failure of business operations. Biorepositories are also at risk and there have been instances where multiple samples or entire collections have been destroyed. Biobank guidelines accordingly recommend the establishment of contingency plans to reduce risk to an acceptable level. In this review article, we will use general theory on risk management and illustrate how such principles can be used to establish a practical crisis management plan for any biobank organization.

URTeC 1577279 This paper illustrates the impact of various complex behaviors on the long-term decline of unconventional wells. These are illustrated through numerical simulations and field production data which are compared to the various forms of expected decline behavior. The simulations are based on modeling and history matching of unconventional systems developed with horizontal wells and multi-stage hydraulic fractures. This paper focuses on tight oil systems. There are many instances where idealized plots are useful for diagnosing and comparing well performance (e.g. hyperbolic decline (Arps), square-root of time, power-law exponential, other hybrid methods and type curves). However, in many cases such decline curves do not adequately describe long-term production behavior. Early in the well life it is especially difficult to determine which relation will best fit the long term performance. Also as new wells are added interference can cause significant deviations from the earlier behavior. This paper will illustrate the causes and characteristics of long-term decline in complex systems to aid as a guide in estimating long-term decline behavior. The results of this work illustrate the reasons for deviation from ideal behavior such as changing compressibility and total mobility during multi-phase flow, heterogeneous matrix properties, presence of natural fractures, fracture and matrix compaction and non-uniform hydraulic fracturing. Also, some methods are not applicable for variable rate or variable pressure production scenarios (the most common state of actual well production). The paper addresses the following issues 1) Illustrates non-ideal decline behavior of unconventional reservoirs based on fluid characteristics; 2) Illustrates non-ideal decline behavior of unconventional reservoirs based on reservoir complexities; 3) Limitations of rate transient analysis and decline curve analysis methods.
