Diagnostic sequence of cocaine use disorder in relation to other mental health conditions among college students

Abstract

Objective: Cocaine use is increasing. Comorbidities and diagnostic sequencing are needed among college students to inform treatment of cocaine use disorder (CUD). Method: Using electronic medical records from the psychiatric clinic at the student health care center of a large, public university from 2005 to 2015, patients diagnosed with CUD were identified. Their top mental health conditions were identified and assessed to see whether the first diagnosis of these conditions was made (1) before, (2) at the same time as, or (3) after the first diagnosis of CUD. Results: Among the 50 CUD patients, their most common mental health comorbidities were alcohol use disorder, anxiety, depression, and cannabis use disorder. Anxiety and depression were likely to be diagnosed before CUD; alcohol and cannabis use disorders were likely to be diagnosed concurrently with CUD. Conclusion: Diagnostic sequencing can be used to inform screening, workup, and treatment for patients with CUD.     

New Modified Scrambled Faure Sequences

In this paper, we introduce two new modified scrambled Faure sequences based on linear digit scrambling method with good two-dimensional projections in consecutive dimensions using two new linear digit scrambling matrices for linear and nonlinear scrambled Faure sequences. Also, we present performance of our two new scrambling methods by two-dimensional projections and test-integrals.     

清代世爵世职承袭制度的几个问题

清代的世职承袭自天聪以降,一直存在着世袭罔替和按次承袭两种选择方式,清初决定两种方式选择的主要依据是天聪五年的功臣袭职例,这也一定程度导致了清初按次承袭的混乱,顺治年间虽有统一规定,但承袭方式不同的特色仍得以延续.承袭人的择取不似承袭方式混乱,却也经过了前后细微的变化.     

人民币资本项目开放的理论探讨

随着合格境外机构投资者制度(QFII)的推出,我国正在逐步放松对资本项目的管制,加大资本项目开放的力度。但在开放过程中,有三个问题显得尤为重要:一是如何认识在存在着较多风险的情况下,我国加快资本项目开放的必然性;二是如何选择开放次序,从而使开放过程风险可控有序地推进;三是如何分析和防范开放过程中的各类风险,以保证宏观经济的稳定。本文就这些问题进行了探讨。

What do we call post-apartheid?

In this paper, the author examines the different uses and meanings of the usual expression “post-apartheid.” It has been used extensively in the social sciences, political discourse and the media since the mid-1980s. But what does it refer to, and has it always meant the same thing over the last 20 years? To answer that question, the author reviews the different ways she has used the notion in her research into workers’ forms of thinking and political subjectivities in South Africa since 1996. She distinguishes between its use as a chronological marker, an academic concept open to various problematics and epistemological decisions and a notion used by interviewees under various acceptations. She concentrates more specifically on the sequential implications of the adverb “post” in her work and argues that there have been political sequences in what she (with others) has named “post-apartheid.” She concludes that she intends to stop using this term in order to concentrate on identifying the current political sequence in South Africa.     

安大简《国风》的次序及“侯风”试解

安大简《国风》并非全本,各风次序与今本《诗经》不尽相同,但其相对次序值得重视。在安大简中,《秦》在《魏》前,与《左传》相合;在安大简中,《侯》在《魏》前,从其实际内容看,相当于《魏》在《唐》前,与传世古书的次序相合。有一种可能性的解释是《侯》即《唐》,安大简中关于《魏》《唐》的实际相对次序与传世古书并无二致,但安大简的抄写者误将“侯(唐)”“魏”的风名分别安到《魏》和《侯(唐)》之上。     

Postdisaster Housing Stages: A Markov Chain Approach to Model Sequences and Duration Based on Social Vulnerability

Housing recovery is an unequal and complex process presumed to occur in four stages: emergency shelter, temporary shelter, temporary housing, and permanent housing. This work questions the four-stage typology and examines how different types of shelter align with multiple housing recovery stages given different levels of social vulnerability. This article also presents a Markov chain model of the postdisaster housing recovery process that focuses on the experience of the household. The model predicts the sequence and timing of a household going through housing recovery, capturing households that end in either permanent housing or a fifth possible stage of failure. The probability of a household transitioning through the stages is computed using a transition probability matrix (TPM). The TPM is assembled using proposed transition probability models that vary with the social vulnerability of the household. Monte Carlo techniques are applied to demonstrate the range of sequences and timing that households experience going through the housing recovery process. A set of computational rules are established for sending a household to the fifth stage, representing a household languishing in unstable housing. This predictive model is exemplified on a virtual community, Centerville, where following a severe earthquake scenario, differences in housing recovery times exceed four years. The Centerville analysis results in nearly 5% of households languishing in unstable housing, thereby failing to reach housing recovery. These findings highlight the disparate trajectories experienced by households with different levels of social vulnerability. Recommendations are provided at the end for more equitable postdisaster recovery policies.     

四川盆地雷口坡组层序岩相古地理

针对四川盆地各矿区雷口坡组地层划分方案不统一，且受早印支运动的影响，雷口坡组顶部岩溶带地层垮塌破坏，造成地层内幕划分及岩相古地理恢复困难的难题，以层序地层学理论与方法为指导，重新厘定了盆地内雷口坡组的地层划分方案，以四级层序为作图单元进行层序岩相古地理重建。高精度的层序岩相古地理研究表明，雷口坡期四川盆地处于局限–蒸发海环境，在川西北一带靠近松潘—甘孜海槽一带发育有台地边缘，台地内部颗粒滩和台地边缘颗粒滩构成了雷口坡组的勘探主体。岩相古地理的演化表明，雷口坡组沉积时期盆地底形发生了东倾向西倾“跷跷板”式的转换，在层序I 早期仍保持了早三叠世西高东低的地形格局，至层序III 沉积期东倾趋势消失，层序IVV 沉积时期盆地内隆凹格局略具雏形。伴随着构造挤压运动的加剧，从层序VI 开始盆地底形隆凹格局分异加剧，形成巨厚膏盐盆，膏盐盆沉积中心在层序VIX 沉积时期具有明显西移的趋势。
