An interactive web-based method of outreach to college students at risk for suicide

OBJECTIVE AND PARTICIPANTS: From 2002 to 2005, the authors tested an interactive, Web-based method to encourage college students at risk for suicide to seek treatment. METHODS: The authors invited students at 2 universities to complete an online questionnaire that screened for depression and other suicide risk factors. Respondents received a personalized assessment and were able to communicate anonymously with a clinical counselor online. At-risk students were urged to attend in-person evaluation and treatment. RESULTS: A total of 1,162 students (8% of those invited) completed the screening questionnaire; 981 (84.4%) were designated as at high or moderate risk. Among this group, 190 (19.4%) attended an in-person evaluation session with the counselor, and 132 (13.5%) entered treatment. Students who engaged in online dialogues with the counselor were 3 times more likely than were those who did not to come for evaluation and enter treatment. CONCLUSIONS: The method has considerable promise for encouraging previously untreated, at-risk college students to get help.     

我们康德主义者——论当前的"批判道路"

康德对于当代世界的重要意义在于,现代性文化的基本原则在其哲学中得到了最初的或许也是最明确的表达.这些原则包括批判性反思、世俗化、多元性等.虽然其先验哲学的理性奠基的理想、表象-意义分析理论等已不再适用,但就我们仍然处于康德所定义的文化语境来说,当今时代的哲学思考注定无法绕过康德.     

Using Real‐Time Decision Tools to Improve Distributed Decision‐Making Capabilities in High‐Magnitude Crisis Situations*

Multi‐organizational collaborative decision making in high‐magnitude crisis situations requires real‐time information sharing and dynamic modeling for effective response. Information technology (IT) based decision support tools can play a key role in facilitating such effective response. We explore one promising class of decision support tools based on machine learning, known as support vector machines (SVM), which have the capability to dynamically model and analyze decision processes. To examine this capability, we use a case study with a design science approach to evaluate improved decision‐making effectiveness of an SVM algorithm in an agent‐based simulation experimental environment. Testing and evaluation of real‐time decision support tools in simulated environments provides an opportunity to assess their value under various dynamic conditions. Decision making in high‐magnitude crisis situations involves multiple different patterns of behavior, requiring the development, application, and evaluation of different models. Therefore, we employ a multistage linear support vector machine (MLSVM) algorithm that permits partitioning decision maker response into behavioral subsets, which can then individually model and examine their diverse patterns of response behavior. The results of our case study indicate that our MLSVM is clearly superior to both single stage SVMs and traditional approaches such as linear and quadratic discriminant analysis for understanding and predicting behavior. We conclude that machine learning algorithms show promise for quickly assessing response strategy behavior and for providing the capability to share information with decision makers in multi‐organizational collaborative environments, thus supporting more effective decision making in such contexts.     

The State and its Welfare State: How do Welfare State Changes Affect the Make‐up of the Nation State?

With respect to changes in the welfare states of OECD countries, scholars most of the time are looking for common trends; that is, they look for similar movements in different states, such as welfare state retrenchment, recalibration, etc. As we show in this article, data on welfare state spending and financing do not, however, support such stark tendencies like retrenchment. We therefore suggest looking for corridor effects rather than level effects, i.e. analysing changes in the dispersion of welfare state regimes rather than shifts in the mean values. Our analysis suggests that convergence, i.e. decreasing diversity among states in spending, financing and regulation patterns, may have been the most important pattern of welfare state change in the last three decades – a pattern easily overlooked in past and current research. Convergence of welfare state regimes also affects our views on the modern nation state itself since the varieties of welfare capitalism in the twentieth century are themselves an expression of the sovereignty and autonomy of the nation state. If nation states are forced to surrender national particularities, to mellow their characteristic differences and to move incrementally towards a one‐size‐fits‐all common model via ‘shrinking corridors’, such a blurring of welfare regimes, such a beclouding of difference, should also be regarded as a significant change taking place in the centre of the Western nation state's make‐up.
