Commissioned Paper: Capacity Management, Investment, and Hedging: Review and Recent Developments

This paper reviews the literature on strategic capacity management concerned with determining the sizes, types, and timing of capacity investments and adjustments under uncertainty. Specific attention is given to recent developments to incorporate multiple decision makers, multiple capacity types, hedging, and risk aversion. Capacity is a measure of processing abilities and limitations and is represented as a vector of stocks of various processing resources, while investment is the change of capacity and includes expansion and contraction. After discussing general issues in capacity investment problems, the paper reviews models of capacity investment under uncertainty in three settings:The first reviews optimal capacity investment by single and multiple risk-neutral decision makers in a stationary environment where capacity remains constant. Allowing for multiple capacity types, the associated optimal capacity portfolio specifies the amounts and locations of safety capacity in a processing network. Its key feature is that it is unbalanced; i.e., regardless of how uncertainties are realized, one typically will never fully utilize all capacities. The second setting reviews the adjustment of capacity over time and the structure of optimal investment dynamics. The paper ends by reviewing how to incorporate risk aversion in capacity investment and contrasts hedging strategies involving financial versus operational means.
Synthesis, Antimycobacterial, Antifungal and Photosynthesis-Inhibiting Activity of Chlorinated N-phenylpyrazine-2-carboxamides †

A series of sixteen pyrazinamide analogues with the -CONH- linker connecting the pyrazine and benzene rings was synthesized by the condensation of chlorides of substituted pyrazinecarboxylic acids with ring-substituted (chlorine) anilines. The prepared compounds were characterized and evaluated for their antimycobacterial and antifungal activity, and for their ability to inhibit photosynthetic electron transport (PET). 6-Chloro-N-(4-chlorophenyl)pyrazine-2-carboxamide manifested the highest activity against Mycobacterium tuberculosis strain H37Rv (65% inhibition at 6.25 μg/mL). The highest antifungal effect against Trichophyton mentagrophytes, the most susceptible fungal strain tested, was found for 6-chloro-5-tert-butyl-N-(3,4-dichlorophenyl)pyrazine-2-carboxamide (MIC = 62.5 μmol/L). 6-Chloro-5-tert-butyl-N-(4-chlorophenyl)pyrazine-2-carboxamide showed the highest PET inhibition in spinach chloroplasts (Spinacia oleracea L.) chloroplasts (IC50 = 43.0 μmol/L). For all the compounds, the relationships between the lipophilicity and the chemical structure of the studied compounds as well as their structure–activity relationships are discussed.
Research on psychosocial risks at work: a bibliometric study of brazilian national production from 2008 to 2017

The research on psychosocial risks at work has been developing in the world in the last three decades, in the attempt to understand this class of occupational risks. In order to characterize this field of study, the bibliometric analysis of the Brazilian national production from 2008 to 2017 was carried out. We identified 37 articles that were analyzed regarding the area of the journal, temporal evolution, institutional affiliation, co-authoring relations, number of references, number of citations, type of study, and instruments. The bibliometric indicators were analyzed through non-parametric tests. The results indicate a stationary production, with a predominance of publications in the Nursing and Public Health area. We identified isolated groups of researchers, with low participation of researchers in the field of psychology. Empirical studies are largely descriptive and centered on health professions. The conclusions point to the need for greater integration between researchers and the development of long-term research projects.

Monotones and invariants for multi-particle quantum states

We introduce new entanglement monotones which generalize, to the case of many parties, those which give rise to the majorization-based partial ordering of bipartite states' entanglement. We give some examples of restrictions they impose on deterministic and probabilistic conversion between multipartite states via local actions and classical communication. These include restrictions which do not follow from any bipartite considerations. We derive supermultiplicativity relations between each state's monotones and the monotones for collective processing when the parties share several states. We also investigate polynomial invariants under local unitary transformations, and show that a large class of these are invariant under collective unitary processing and also multiplicative, putting restrictions, for example, on the exact conversion of multiple copies of one state to multiple copies of another.
Cotton GhMKK1 Induces the Tolerance of Salt and Drought Stress, and Mediates Defence Responses to Pathogen Infection in Transgenic Nicotiana benthamiana

Mitogen-activated protein kinase kinases (MAPKK) mediate a variety of stress responses in plants. So far little is known on the functional role of MAPKKs in cotton. In the present study, Gossypium hirsutum MKK1 (GhMKK1) function was investigated. GhMKK1 protein may activate its specific targets in both the nucleus and cytoplasm. Treatments with salt, drought, and H2O2 induced the expression of GhMKK1 and increased the activity of GhMKK1, while overexpression of GhMKK1 in Nicotiana benthamiana enhanced its tolerance to salt and drought stresses as determined by many physiological data. Additionally, GhMKK1 activity was found to up-regulate pathogen-associated biotic stress, and overexpression of GhMKK1 increased the susceptibility of the transgenic plants to the pathogen Ralstonia solanacearum by reducing the expression of PR genes. Moreover, GhMKK1-overexpressing plants also exhibited an enhanced reactive oxygen species scavenging capability and markedly elevated activities of several antioxidant enzymes. These results indicate that GhMKK1 is involved in plants defence responses and provide new data to further analyze the function of plant MAPK pathways.
Irregular Puncturing for Convolutional Codes and the Application to Unequal Error Protection

In this paper, convolutional codes are studied for puncturing with irregular puncturing periods. Irregular puncturing can generate punctured codes with more available rates and better bit-error-rate performance compared with the conventional scheme with a single puncturing period. For the application to unequal error protection, a new multiplexing scheme is also proposed for rate-compatible punctured convolutional (RCPC) codes which can guarantee smooth transition between rates without extra overheads. Finally, families of good RCPC codes with irregular puncturing tables are given by a computer search
Verifiable and private top-k monitoring ( short paper )

In a data streaming model, records or documents are pushed from a data owner, via untrusted third-party servers, to a large number of users with matching interests. The match in interest is calculated from the correlation between each pair of document and user query. For scalability and availability reasons, this calculation is delegated to the servers, which gives rise to the need to protect the privacy of the documents and user queries. In addition, the users need to guard against the eventuality of a server distorting the correlation score of the documents to manipulate which documents are highlighted to certain users. In this paper, we address the aforementioned privacy and verifiability challenges. We introduce the first cryptographic scheme which concurrently safeguards the privacy of the documents and user queries in such a data streaming model, while enabling users to verify the correlation scores obtained. We provide techniques to bound the computation demand in decrypting the correlation scores, and we demonstrate the overall practicality of the scheme through experiments with real data.
Way Memoization to Reduce Fetch Energy in Instruction Caches

Instruction caches consume a large fraction of the total power in modern low-power microprocessors. In particular, set-associative caches, which are preferred because of lower miss rates, require greater access energy on hits than direct-mapped caches; this is because of the need to locate instructions in one of several ways. Way prediction has been proposed to reduce power dissipation in conventional set-associative caches; however, its application to CAMtagged caches, which are commonly used in low-power designs, is problematic and has not been quantitatively examined. We propose way memoizationas an alternative to way prediction. As in way prediction schemes, way memoization stores way information (links) within the instruction cache, but in addition maintains a valid bit per link that when set guarantees that the way link is valid. In contrast, way prediction schemes must always read one tag to verify that the prediction is correct. Way memoization requires a link invalidation mechanism to maintain the coherence of link information. We investigate several invalidation schemes and show that simple conservative global invalidation schemes perform similarly to exact invalidation schemes but with much lower implementation cost. Based on HSPICE simulations of complete cache layouts in a 0.25 mC MOS process, and processor simulations running SPECint95 and MediaBench benchmarks, we show that way memoization reduces the energy of a highly-optimized 16 KB 64-way CAM-tag low-power instruction cache by 21%, an additional 13% savings compared to a way-predicting cache.
A Formal Approach to Test the Robustness of Embedded Systems using Behaviour Analysis

Robustness is an important feature required for embedded systems. This paper presents a methodology to test robustness of such systems. We investigate system behaviour aspects. We handle two formal specifications : a nominal one which describes the system behaviour in normal conditions and a degraded one which describes the behaviour in critical conditions. Both are described as Labelled Transition Systems for the untimed systems and as Timed Automata for timed systems. We extract test sequences from the nominal or from the degraded specification. We perform fault injection on these test sequences. Finally, we submit these sequences to the Implementation Under Test (IUT) and then we analyze its behaviour using adequate robustness relations.
Integrating support for undo with exception handling

One of the important tasks of exception handling is to restore program state and invariants. Studies suggest that this is often done incorrectly. We introduce a new language construct that integrates automated memory recovery with exception handling. When an exception occurs, memory can be automatically restored to its previous state. We also provide a mechanism for applications to extend the automatic recovery mechanism with callbacks for restoring the state of external resources. We describe a logging-based implementation and evaluate its effect on performance. The implementation imposes no overhead on parts of the code that do not make use of this feature.
The Coming of Secular Buddhism: a Synoptic View

Secular Buddhism is coalescing today in response to two main factors. First, it rejects the incoherence of Buddhist modernism, a protean formation that accommodates elements as far afield as ancestral Buddhism and psychotherapies claiming the Buddhist brand. Second, it absorbs the cultural influence of modern secularity in the West. Historically understood, secularity has constituted a centuries-long religious development, not a victory of "science" over "religion. " Today's secularity marks a further stage in the cultural decline of "enchanted" truth-claims and the intellectual eclipse of metaphysics, especially under the aegis of phenomenology. In Buddhism as in Christianity, secularity brings forth a new humanistic approach to ethical-spiritual life and creative this-worldly practices.
Organizational Climate and Student Achievement: A Parsimonious and Longitudinal View

Health and openness metaphors are used to develop measures of organizational climate. In addition to socioeconomic status, Environmental Press, Collegial Leadership, Teacher Professionalism, and Academic Press are aspects of climate that make significant, independent contributions to student achievement in basic skills and explain a substantial amount of the variance. Moreover, the influence of school climate on achievement is enduring over several years. The proposed climate framework underscores important linkages between the institutional, managerial, technical, and client levels in service organizations such as schools.
Model update in wearable sensors based human activity recognition

In this article wearable sensors based human activity recognition is approached with a case where personal data collected has a high inner activity variety. With this kind of approach, the model adaptivity as well as update becomes more important issues for the activity recognition models. In authors' previous article it was shown that with this kind of data the personal models do not always outperform the user-independent models and a self-organising maps distance based approach was introduced to be used in personal and UI model fusion. In this work, the idea is developed further and it is shown that the same procedure can and should be used as predictive model as well as in data labeling also when updating the models in real-life. It is shown that compared to results of updating personal model our approach gives from 0.6 to 8.2 percentage units improvement in overall accuracy. In practice, just updating personal model with its given somewhat mislabeled data can in the worst case even drop the recognition accuracy by several percentage units which is an unwanted effect in real world applications.
Discussions about indigenous, national and transnational Islam in Russia

ABSTRACT Transnational Islam is increasingly presented in the Russian political rhetoric as a security threat. Therefore, Russian politicians and authorities attempt to support indigenous or national forms of Islam. Similar policies are implemented in several western European countries. Yet they tend to disregard the heterogeneity of the Muslim community, they create exclusions and they are often conceived as imposing outside evaluations and interpretations on Islam. This contribution analyses initiatives intended to develop a national Islam in post-Soviet Russia. While the aims, methods and problems in different countries are often quite similar, the values and norms underlying these initiatives vary and reflect the societies from which they emerge. This contribution argues that since the 1990s, the changes in the political line of the Kremlin have impacted the project for a ‘national’ Islam by placing less emphasis on liberal values and more emphasis on adherence to loyalism and political conservatism.
Analysis of spatial partitioning approaches for image classification

Spatial partitioning is proven to be beneficial for the tasks of image classification, scene categorization and object recognition. The most popular method to capture rough spatial structure of the scene is spatial pyramid matching. However, spatial pyramid matching results in an image representation that is sensitive to rotations. In this research we investigate the influence of upright and rotated partitions on image classification regardless of the image filtering step. We show that simple combination of rotated spatial partitions improves classification accuracy up to 10% compared to single spatial partition commonly used in spatial pyramid matching.
CARD15/NOD2 Is Required for Peyer's Patches Homeostasis in Mice

Background CARD15/NOD2 mutations are associated with susceptibility to Crohn's Disease (CD) and Graft Versus Host Disease (GVHD). CD and GVHD are suspected to be related with the dysfunction of Peyer's patches (PP) and isolated lymphoid follicles (LFs). Using a new mouse model invalidated for Card15/Nod2 (KO), we thus analysed the impact of the gene in these lymphoid formations together with the development of experimental colitis. Methodology/Principal Findings At weeks 4, 12 and 52, the numbers of PPs and LFs were higher in KO mice while no difference was observed at birth. At weeks 4 and 12, the size and cellular composition of PPs were analysed by flow cytometry and immunohistochemistry. PPs of KO mice were larger with an increased proportion of M cells and CD4+ T-cells. KO mice were also characterised by higher concentrations of TNFα, IFNγ, IL12 and IL4 measured by ELISA. In contrast, little differences were found in the PP-free ileum and the spleen of KO mice. By Ussing chamber experiments, we found that this PP phenotype is associated with an increased of both paracellular permeability and yeast/bacterial translocation. Finally, KO mice were more susceptible to the colitis induced by TNBS. Conclusions Card15/Nod2 deficiency induces an abnormal development and function of the PPs characterised by an exaggerated immune response and an increased permeability. These observations provide a comprehensive link between the molecular defect and the Human CARD15/NOD2 associated disorders: CD and GVHD.
Pharmacological profiling of the hemodynamic effects of cannabinoid ligands: a combined in vitro and in vivo approach

The receptors mediating the hemodynamic responses to cannabinoids are not clearly defined due to the multifarious pharmacology of many commonly used cannabinoid ligands. While both CB1 and TRPV1 receptors are implicated, G protein‐coupled receptor 55 (GPR55) may also mediate some of the hemodynamic effects of several atypical cannabinoid ligands. The present studies attempted to unravel the pharmacology underlying the in vivo hemodynamic responses to ACEA (CB1 agonist), O‐1602 (GPR55 agonist), AM251 (CB1 antagonist), and cannabidiol (CBD; GPR55 antagonist). Agonist and antagonist profiles of each ligand were determined by ligand‐induced GTPγS binding in membrane preparations expressing rat and mouse CB1 and GPR55 receptors. Blood pressure responses to ACEA and O‐1602 were recorded in anesthetized and conscious mice (wild type, CB1−/− and GPR55−/−) and rats in the absence and presence of AM251 and CBD. ACEA demonstrated GTPγS activation at both receptors, while O‐1602 only activated GPR55. AM251 exhibited antagonist activity at CB1 and agonist activity at GPR55, while CBD demonstrated selective antagonist activity at GPR55. The depressor response to ACEA was blocked by AM251 and attenuated by CBD, while O‐1602 did not induce a depressor response. AM251 caused a depressor response that was absent in GPR55−/− mice but enhanced by CBD, while CBD caused a small vasodepressor response that persisted in GPR55−/− mice. Our findings show that assessment of the pharmacological profile of receptor activation by cannabinoid ligands in in vitro studies alongside in vivo functional studies is essential to understand the role of cannabinoids in hemodynamic control.
Testing the Significance of Categorical Predictor Variables in Nonparametric Regression Models

In this paper we propose a test for the significance of categorical predictors in nonparametric regression models. The test is fully data-driven and employs cross-validated smoothing parameter selection while the null distribution of the test is obtained via bootstrapping. The proposed approach allows applied researchers to test hypotheses concerning categorical variables in a fully nonparametric and robust framework, thereby deflecting potential criticism that a particular finding is driven by an arbitrary parametric specification. Simulations reveal that the test performs well, having significantly better power than a conventional frequency-based nonparametric test. The test is applied to determine whether OECD and non-OECD countries follow the same growth rate model or not. Our test suggests that OECD and non-OECD countries follow different growth rate models, while the tests based on a popular parametric specification and the conventional frequency-based nonparametric estimation method fail to detect any significant difference.
Creativity and the Management of Attention with Social Media

Social media has transformed the web into a hyper-connected social space that is inundated by a flood of social signals that reflects the activities of the members, and contributes to the dynamic of the interaction. In this context, the participants decode, process and emit information for making sense of this social world, and for acting upon it. The objective of this paper is to explore the implication of this setting for an application in the context of supporting creativity online. More specifically, we examine the effect of the massive circulation of this social information and its management on systems supporting the collective creative process online
