Functional regulatory spaces

This article develops the concept of “Functional Regulatory Space” (FRS) in order to analyze the new forms of State action addressing (super) wicked problems. A FRS simultaneously spans several policy sectors, institutional territories and levels of government. It suggests integrating previous policy theories that focused on “boundary-spanning regime,” “territorial institutionalism” or multi-level governance. The FRS concept is envisaged as a Weberian “ideal-type” of State action and is applied to the empirical study of two European cases of potential FRS: the integrated management of water basins and the regulation of the European sky through functional airspace blocks. It will be concluded that the current airspace regulation does match the ideal-type of FRS any better than the water resource regulation does. The next research step consists in analyzing the genesis and institutionalization of potential FRS addressing other (super) wicked problems such as climate change and economic, security, health and immigration issues in different institutional contexts as well as at various levels of governance.

Dimensions of the Ascending Aorta in Conotruncal Heart Defects

Dilatation of the ascending aorta is an important sequel in conotruncal anomalies, such as tetralogy of Fallot (TOF) or d-transposition of the great arteries (TGA). We measured dimensions and their progression at different levels of the ascending aorta in 80 patients. In TOF patients, mean z-score for aortic annulus was 1.65 (range -3.16-6.47), for sinus 1.93 (range -2.28-5.39), for st-junction 4.15 (range 0.0-8.18), and for ascending aorta 3.51 (range -1.23-6.36). Over time, annulus z-scores increased in the univariate analysis [0.07/year, 95 % confidence interval (CI) 0.01-0.14; p = 0.02], and this was unique to male patients (0.08/year, 95 % CI 0.00-0.15; p = 0.05). z-scores of the ascending aorta decreased (-0.1/year, 95 % CI -0.18 to -0.02; p = 0.02), and this was confined to patients without aortic regurgitation (AR; -0.09/year, 95 % CI -0.18 to -0.01; p = 0.04). In TGA, mean z-score for the aortic annulus was 2.13 (range -3.71-8.39), for sinus 1.77 (range -3.04-6.69), for st-junction 1.01 (range -5.44-6.71), and for ascending aorta 0.82 (range -4.91-6.46). In bivariate analysis, annulus z-scores decreased in females (-0.14/year, 95 % CI -0.25 to -0.03; p = 0.01) and in patients without AR (-0.07/year, 95 % CI -0.14-0.0; p = 0.03). z-scores of the ascending aorta increased significantly in males (0.08/year, 95 % CI 0.0 to 0.16; p = 0.05) and in patients with AR (0.12/year, 95 % CI 0.03-0.21; p = 0.01). In conclusion, TOF and TGA z-scores of the ascending aorta differ significantly from those of the normal population. Progression of z-scores over time is influenced by diagnosis, sex, and presence of AR.

Peptide receptor radionuclide therapy in a patient with disabling non-functioning pituitary adenoma

Non-functioning pituitary adenoma (NFPA) with higher proliferation index (WHO II) are often a therapeutical challenge. Low somatostatin receptor expression in these tumors usually prevents a treatment with somatostatin analogs. In 1996, a 55-year-old patient was referred due to right-sided headache. A pituitary macroadenoma with infiltration into the right cavernous sinus was diagnosed. There was no visual field deficit and the clinical and biochemical work up was consistent with a NFPA. The patient underwent transsphenoidal surgery. Residual adenoma remained in the right cavernous sinus. Histologically, a null-cell adenoma with a high proliferation index was documented (MIB-1: 11.6 %, WHO II). Somatostatin receptor autoradiography was performed in the surgical specimen showing a homogenous expression of sst2 receptors. Radiosurgery was completed with stable disease for 8 years. In 2004, the patient was diagnosed with an incomplete palsy of the right oculomotorius nerve and a significant increase in the volume of the adenoma in the right cavernous sinus. After a positive Octreoscan(®) the patient consented to an experimental therapy approach using Lutetium DOTATOC (3 × 200 mCi). The palsy of the oculomotorius nerve improved and remained stable until today (March 2013), the follow-up MRI scans demonstrated stable disease. This is the first case of a patient with a NFPA (WHO II) in whom PRRT successfully improved the local complications of the tumor for more than 8 years after ineffective surgery and gamma knife therapy. The determination of sst2 in vitro using autoradiography and in vivo by Octreoscan was instrumental to administer this therapy in a challenging situation.

The impact of retrieval processes, age, general achievement level, and test scoring scheme for children's metacognitive monitoring and controlling

This multi-phase study examined the influence of retrieval processes on children’s metacognitive processes in relation to and in interaction with achievement level and age. First, N = 150 9/10- and 11/12-year old high and low achievers watched an educational film and predicted their test performance. Children then solved a cloze test regarding the film content including answerable and unanswerable items and gave confidence judgments to every answer. Finally, children withdrew answers that they believed to be incorrect. All children showed adequate metacognitive processes before and during test taking with 11/12- year-olds outperforming 9/10-year-olds when considering characteristics of on-going retrieval processes. As to the influence of achievement level, high compared to low achievers proved to be more accurate in their metacognitive monitoring and controlling. Results suggest that both cognitive resources (operationalized through achievement level) and mnemonic experience (assessed through age) fuel metacognitive development. Nevertheless, when facing higher demands regarding retrieval processes, experience seems to play the more important role.

Executive functioning, metacognition, and self-perceived competence in elementary school children: An explorative study on their interrelations and their role for school achievement

In the present study, associations between executive functioning, metacognition, and self-perceived competence in the context of early academic outcomes were examined. A total of 209 children attending first grade were initially assessed in terms of their executive functioning and academic self-concept. One year later, children’s executive functioning, academic self-concept, metacognitive monitoring and control, as well as their achievement in mathematics and literacy were evaluated. Structural equation modeling revealed that executive functioning was significantly related to metacognitive control, both cross-sectionally and longitudinally, and that self-concept was substantially associated with metacognitive monitoring, both cross-sectionally and longitudinally. Individual differences in executive functioning and metacognitive control were significantly related to academic outcomes, with metacognitive control appearing to yield a more circumscribed influence on academic outcomes (only literacy) compared to executive functioning (literacy and mathematics).

Can you see me thinking (about my answers)? Using eye-tracking to illuminate developmental differences in monitoring and control skills and their relation to performance

This study focuses on relations between 7- and 9-year-old children’s and adults’ metacognitive monitoring and control processes. In addition to explicit confidence judgments (CJ), data for participants’ control behavior during learning and recall as well as implicit CJs were collected with an eye-tracking device (Tobii 1750). Results revealed developmental progression in both accuracy of implicit and explicit monitoring across age groups. In addition, efficiency of learning and recall strategies increases with age, as older participants allocate more fixation time to critical information and less time to peripheral or potentially interfering information. Correlational analyses, recall performance, metacognitive monitoring, and controlling indicate significant interrelations between all of these measures, with varying patterns of correlations within age groups. Results are discussed in regard to the intricate relationship between monitoring and recall and their relation to performance.

A mixed-integer linear programming approach to the optimization of event-bus schedules: a scheduling application in the tourism sector

This paper deals with “The Enchanted Journey,” which is a daily event tour booked by Bollywood-film fans. During the tour, the participants visit original sites of famous Bollywood films at various locations in Switzerland; moreover, the tour includes stops for lunch and shopping. Each day, up to five buses operate the tour. For operational reasons, however, two or more buses cannot stay at the same location simultaneously. Further operative constraints include time windows for all activities and precedence constraints between some activities. The planning problem is how to compute a feasible schedule for each bus. We implement a two-step hierarchical approach. In the first step, we minimize the total waiting time; in the second step, we minimize the total travel time of all buses. We present a basic formulation of this problem as a mixed-integer linear program. We enhance this basic formulation by symmetry-breaking constraints, which reduces the search space without loss of generality. We report on computational results obtained with the Gurobi Solver. Our numerical results show that all relevant problem instances can be solved using the basic formulation within reasonable CPU time, and that the symmetry-breaking constraints reduce that CPU time considerably.

Intentionality in Reference and Action

This essay asks whether there is a relation between action-serving and meaning-serving intentions. The idea that the intentions involved in meaning and action are nominally designated alike as intentionalities does not guarantee any special logical or conceptual connections between the intentionality of referential thoughts and thought-expressive speech acts with the intentionality of doing. The latter category is typified by overt physical actions in order to communicate by engaging in speech acts, but also includes at the origin of all artistic and symbolic expression such cerebral and linguistic doings as thinking propositional thoughts. There are exactly four possibilities by which meaning and action intentionalities might be related to be systematically investigated. Meaning-serving and action-serving intentionalities, topologically speaking, might exclude one another, partially overlap with one another, or subsume one in the other or the other in the one. The theoretical separation of the two ostensible categories of intendings is criticized, as is their partial overlap, in light of the proposal that thinking and artistic and symbolic expression are activities that favor the inclusion of paradigm meaning-serving intentions as among a larger domain of action-serving intentions. The only remaining alternative is then developed, of including action-serving intentions reductively in meaning-serving intentions, and is defended as offering in an unexpected way the most cogent universal reductive ontology in which the intentionality of doing generally relates to the specific intentionality of referring in thought to the objects of predications, and of its artistic and symbolic expression.

Novel Nonbiologic Therapies for Ulcerative Colitis

An extensive array of compounds has been studied for the treatment of ulcerative colitis (UC). The most frequently used nonbiologic drugs for the oral and intravenous treatment of ulcerative colitis include 5-aminosalicylate (5-ASA) drugs (mesalamine and derivatives), sulfasalazine, and other azo-bonded molecules of 5-ASA, steroids, calcineurin inhibitors (cyclosporine, tacrolimus, and sirolimus), thiopurines (azathioprine, 6-mercaptopurine), and methotrexate, which are already presented in other sections of this book and are thus not considered in this chapter. The therapies presented in this section should be considered as potential alternatives, mostly for mild-to-moderate ulcerative colitis (UC). They are substances mostly used without FDA indications, such as heparin, nicotine, rosiglitazone, and N-acetylcysteine as well as “natural” compounds suggested to have anti-inflammatory or reparative properties, such as aloe vera, curcumin, short-chain fatty acids, and Bowman-Birk inhibitor
