PoDeA, Port development Argentina

This report contains the conceptual lay-out for two possible expansions of the port of Bahia Blanca. To determine the best conceptual lay-outs, emphasis is drawn to understand the physical system to determine the effect of the expansion of the port on the natural system. The port of Bahia Blanca is situated at the end of a ria, or tidal basin. For the designs, different conceptual lay-outs are developed and simulated in a hydrodynamic model called MOHID. This is a 2D depth-averaged model (2DH), which uses a rough bathymetry grid of the ria to determine the effect of the port development. There are three mutations of the different port expansions on the environment, which are investigated using the MOHID-model: (1) the East expansion, containing reclamation of tidal flats and closure of a side channel; (2) the South expansion, containing a widening and elongation of the channel and reclamation of tidal flats; and (3) the deepening of the entire navigation channel to various minimum depths. From the results of the MOHID-model on the East expansion conclusions on the mutations of the different port expansions are drawn. For the East expansion, only small changes are predicted; only local erosion in the navigation channel near the expansion may occur. For the South expansion, the flow velocities reduce in the entire stretch and there seems to be sedimentation at the eastern part of the expansion. As a conclusion the best and most feasible designs are chosen. The best design is the lay-out that obtained the highest score in the MultiCriteria- Analysis (MCA). The most feasible design is the design having the highest cost/benefit ratio determined by a Cost-Benefit Analysis (CBA). The east bank is located close to the current port, Ingeniero White, on tidal flats which are inundated at high-water and dry at low-water. For the East expansion, different port lay-outs are developed mainly differing in amount of reclaimed land, length of viaducts and the presence of a mooring basin. The best design on the east is characterised as being very compact and having small viaducts between the dry bulk and agribulk terminals and jetties. The main advantage of this design is the small expected increase of siltation, good safety and sufficient future expansion possibilities. The most feasible design, however, is characterised by long viaducts reducing the costs of the design. The other appointed location for the port expansion is the south bank, opposite of the current port development. This location, however, is characterised by one main disadvantage; It is far from any form of connection with the hinterland. Nevertheless, in 2013, the port authority (CGPBB) initiated the start of small reclamation works. The best and most feasible design fully utilises this reclaimed portion of land. Moreover, the best design has a small expected increase of siltation in the port area. For a final designs, all previous designs are combined to create a design in which all the advantages of each of the designs are fully incorporated. Therefore, this design has little reclamation as well as viaducts with only intermediate lengths.
Reshaping Access Patterns for Improving Data Locality

In this paper, we present a method to construct a loop transformation that simultaneously reshapes the access patterns of several occurrences of multidimensional arrays along certain desired access directions. First, the method determines a direction through the original iteration space along which these desired access directions are induced. Subsequently, a unimodular transformation is constructed that changes the iteration space traversal accordingly. Finally, data dependences are accounted for. In particular, this reshaping method can be used to improve data locality in a program.
The impact of dietary habits and metabolic risk factors on cardiovascular and diabetes mortality in countries of the Middle East and North Africa in 2010: a comparative risk assessment analysis

Objective/design We conducted a comparative risk assessment analysis to estimate the cardiometabolic disease (CMD) mortality attributable to 11 dietary and 4 metabolic risk factors in 20 countries of the Middle East by age, sex and time. The national exposure distributions were obtained from a systematic search of multiple databases. Missing exposure data were estimated using a multilevel Bayesian hierarchical model. The aetiological effect of each risk factor on disease-specific mortality was obtained from clinical trials and observational studies. The number of disease-specific deaths was obtained from the 2010 Global Burden of Disease mortality database. Mortality due to each risk factor was determined using the population attributable fraction and total number of disease-specific deaths. Setting/population Adult population in the Middle East by age, sex, country and time. Results Suboptimal diet was the leading risk factor for CMD mortality in 11 countries accounting for 48% (in Morocco) to 72% (in the United Arab Emirates) of CMD deaths. Non-optimal systolic blood pressure was the leading risk factor for CMD deaths in eight countries causing 45% (in Bahrain) to 68% (in Libya) of CMD deaths. Non-optimal body mass index and fasting plasma glucose were the third and fourth leading risk factors for CMD mortality in most countries. Among individual dietary factors, low intake of fruits accounted for 8% (in Jordan) to 21% (in Palestine) of CMD deaths and low intake of whole grains was responsible for 7% (in Palestine) to 22% (in the United Arab Emirates) of CMD deaths. Between 1990 and 2010, the CMD mortality attributable to most risk factors had decreased except for body mass index and trans-fatty acids. Conclusions Our findings highlight key similarities and differences in the impact of the dietary and metabolic risk factors on CMD mortality in the countries of the Middle East and inform priorities for policy measures to prevent CMD.
Self-efficacy and work-related performance: A meta-analysis.

This meta-analysis (114 studies, k = 157, N = 21,616) examined the relationship between self-efficacy and work-related performance. Results of the primary meta-analysis indicated a significant weighted average correlation between self-efficacy and work-related performance, G (r+) = . 38, and a signif
Vertical partitioning between sister species of Rhizopogon fungi on mesic and xeric sites in an interior Douglas‐fir forest

Understanding ectomycorrhizal fungal (EMF) community structure is limited by a lack of taxonomic resolution and autecological information. Rhizopogon vesiculosus and Rhizopogon vinicolor (Basidiomycota) are morphologically and genetically related species. They are dominant members of interior Douglas‐fir (Pseudotsuga menziesii var. glauca) EMF communities, but mechanisms leading to their coexistence are unknown. We investigated the microsite associations and foraging strategy of individual R. vesiculosus and R. vinicolor genets. Mycelia spatial patterns, pervasiveness and root colonization patterns of fungal genets were compared between Rhizopogon species and between xeric and mesic soil moisture regimes. Rhizopogon spp. mycelia were systematically excavated from the soil and identified using microsatellite DNA markers. Rhizopogon vesiculosus mycelia occurred at greater depth, were more spatially pervasive, and colonized more tree roots than R. vinicolor mycelia. Both species were frequently encountered in organic layers and between the interface of organic and mineral horizons. They were particularly abundant within microsites associated with soil moisture retention. The occurrence of R. vesiculosus shifted in the presence of R. vinicolor towards mineral soil horizons, where R. vinicolor was mostly absent. This suggests that competition and foraging strategy may contribute towards the vertical partitioning observed between these species. Rhizopogon vesiculosus and R. vinicolor mycelia systems occurred at greater mean depths and were more pervasive in mesic plots compared with xeric plots. The spatial continuity and number of trees colonized by genets of each species did not significantly differ between soil moisture regimes.
Development and evaluation of continuing education course in renal nutrition

BACKGROUND/OBJECTIVE Competent renal dietitians are crucial for better patient compliance and clinical outcomes, specifically in critical settings. The aim of this study was to develop and evaluate an evidence-based course in renal dietetics for dietitians working in health care systems where dietetic specialization is absent. SUBJECTS/METHODS Fifteen licensed dietitians working with hemodialysis patients in Lebanon were randomly recruited to participate in the course. The latter was developed by the study's primary investigator, according to evidence-based practice guidelines, and focused on all aspects of renal nutrition. Total course duration was 28 hours spread over a 2 month period. Dietitians' knowledge in renal nutrition was tested pre- and post-training through a 23-item questionnaire; the total score was expressed in percentage (< 60% score indicated insufficient knowledge). Paired-samples t test was used for statistical analysis. RESULTS Overall knowledge of the dietitians significantly improved post-training and reached satisfactory levels (pre: 38.75 ± 17.20%, post: 62.08 ± 21.85%). Sub-analysis of the change in the knowledge showed significant and satisfactory improvement only in 3 topics: 1) correct body weight use in calculations, 2) energy estimation method and 3) phosphorus management. Knowledge in the fluid management significantly improved but did not achieve a satisfactory level. CONCLUSION The course significantly improved dietitians' knowledge in renal nutrition. If adopted as part of the continuing education of dietitians in countries that lack dietetic specializations, it may serve the first step towards improving health care practice.
Use and Non-Use of IT in the Workplace: Studies on Emotions, Identity and Technology

Adoption, acceptance and, more recently, continued use of information technology (IT) in workplace contexts have been researched extensively over the last three decades. As acceptance and use of IT underlie its ability to fulfill expected business benefits, it is unsurprising that researchers have sustained a great interest in the topic. While there is a wealth of cumulative knowledge on adoption and the factors affecting adoption, much less is known about specific patterns of use — ranging from extensive and frequent use to complete non-use — and the reasons behind these patterns. Existing research on both use and non-use of IT has, until very recently, emphasized the technical, cognitive and social aspects that may influence humantechnology interactions. This has left other aspects — such as emotions and selfidentity — of the relationships between social actors and IT relatively unexplored. Accordingly, the goal of this research is to bring people — including their “nonrational” sides — back into Information Systems research, without black-boxing either the IT artifact or the user. Three studies are conducted to achieve this goal; each study focuses on a different aspect of the emotions-identity-IT relationship. Overall, the research contributes to a better theoretical understanding of how social actor emotions and identity influence how and why certain IT systems and specific features of IT systems are used in the workplace, while others are not. The research also contributes to the development of a novel theoretical framework for the study of IT use and non-use from a personalised perspective. From the practical point of view, the research provides novel insights into how to deal with managerially undesirable patterns of use and non-use of IT at work.
Health literacy issues surrounding weight management among African American women: a mixed methods study.

BACKGROUND Individuals with limited health literacy (LHL) have poorer health outcomes and have difficulty understanding and complying with recommendations to maintain a healthy lifestyle. The present study examined the association between health literacy (HL) and sources of dieting information, the weight-loss methods used and the information needed to manage weight among African American women. METHODS This mixed method study included seven focus groups and a survey of 413 African American women. Binary logistic regression analyses were performed to examine the association between HL category and sources of dieting information, weight-loss methods and information needed to lose weight. Thematic analysis was used to analyse focus group data. RESULTS Women with LHL were significantly more likely to have a higher body mass index (BMI) than those with AHL (P < 0.05). Compared to respondents with LHL, those with adequate health literacy (AHL) are more likely to rely on information obtained from the Internet (P < 0.001), although they are less likely to rely on information obtained from the television (P < 0.05). They also are significantly more likely to participate in physical activity to lose weight (P ≤ 0.002). In addition, women with AHL were significantly less likely to want information on portion control (P = 0.002). Major qualitative themes were the importance of television and the Internet as major sources of health information, the use of healthy and unhealthy weight-loss methods, and being overwhelmed by the plethora of dieting information. CONCLUSIONS HL may affect BMI among AA women, where they access dieting information and the types of information needed to manage their weight.
Toward an ecologically meaningful view of resource stoichiometry in DOM-dominated aquatic systems

Research on nutrient controls of planktonic productivity tends to focus on a few standard fractions of inorganic or total nitrogen (N) and phosphorus (P). However, there is a wide range in the degree to which land-derived dissolved organic nutrients can be assimilated by biota. Thus, in systems where such fractions form a majority of the macronutrient resource pool, including many boreal inland waters and estuaries, our understanding of bacterio- and phytoplankton production dynamics remains limited. To adequately predict aquatic productivity in a changing environment, improved standard methods are needed for determining the sizes of active (bioavailable) pools of N, P and organic carbon (C). A synthesis of current knowledge suggests that variation in the C:N:P stoichiometry of bioavailable resources is associated with diverse processes that differentially influence the individual elements across space and time. Due to a generally increasing organic nutrient bioavailability from C to N to P, we hypothesize that the C:N and N:P of bulk resources often vastly overestimates the corresponding ratios of bioavailable resources. It is further proposed that basal planktonic production is regulated by variation in the source, magnitude and timing of terrestrial runoff, through processes that have so far been poorly described.
Translations on a context free grammar

Two schemes for the specification of translations on a context-free grammar are proposed. The first scheme, called a generalized syntax directed translation (GSDT), consists of a context free grammar with a set of semantic rules associated with each production of the grammar. In a GSDT an input word is parsed according to the underlying context free grammar, and at each node of the tree, a finite number of translation strings are computed in terms of the translation strings defined at the descendants of that node. The functional relationship between the length of input and length of output for translations defined by GSDT's is investigated. The second method for the specification of translations is in terms of tree automata - finite automata with output, operating on derivation trees of a context free grammar. It is shown that tree automata provide an exact characterization for those GSDT's with a linear relationship between input and output length.
Double-scattering approximation of lidar equation for inhomogeneous atmosphere.

The lidar equation in a double-scattering approximation, applicable for the case of an inhomogeneous atmosphere, has been derived. It is shown that a doubly scattered flux contains information on the microstructure of the medium investigated. Calculations of the intensity of doubly scattered radiation reflected from clouds are given as an illustrative example. It follows from these calculations that double scattering depends essentially on the distance from the lidar to the cloud sounded.
SmartSleeve: Real-time Sensing of Surface and Deformation Gestures on Flexible, Interactive Textiles, using a Hybrid Gesture Detection Pipeline

Over the last decades, there have been numerous efforts in wearable computing research to enable interactive textiles. Most work focus, however, on integrating sensors for planar touch gestures, and thus do not fully take advantage of the flexible, deformable and tangible material properties of textile. In this work, we introduce SmartSleeve, a deformable textile sensor, which can sense both surface and deformation gestures in real-time. It expands the gesture vocabulary with a range of expressive interaction techniques, and we explore new opportunities using advanced deformation gestures, such as, Twirl, Twist, Fold, Push and Stretch. We describe our sensor design, hardware implementation and its novel non-rigid connector architecture. We provide a detailed description of our hybrid gesture detection pipeline that uses learning-based algorithms and heuristics to enable real-time gesture detection and tracking. Its modular architecture allows us to derive new gestures through the combination with continuous properties like pressure, location, and direction. Finally, we report on the promising results from our evaluations which demonstrate real-time classification.
Executive Information Systems and the Top-Officers' Roles: an exploratory study of user-behaviour model and lessons learnt

In recent years a number of organisations have implemented executive information systems (EIS) in order to improve the performance of their executives’ jobs. Although the use of EIS is important in executives’ work, the majority of executives are unwilling to use EIS applications because of their design flaws. By using social factors, habits and facilitation condition variables from Triandis’ framework, this paper extends the Technology Acceptance Model (TAM) to derive useful variables to address the problem of the low usage of EIS by executives. This paper reports on research in progress in Australia on the adoption and usage of EIS by executives. The preliminary results suggest that executives’ experiences in EIS positively relates to their experiences in computer-based information systems. The results also suggest there is a high degree of perceived usefulness, perceived ease of use as well as positive attitudes towards using EIS. Further, the results suggest that executives consider social factors in using EIS in their work. Moreover, the results suggest that facilitating conditions such as EIS development process, EIS management process and organisational environment are strongly related to the adoption and usage of EIS by executives. Finally, the results suggest a higher degree of EIS usage by middle managers than top-level managers, which an EIS was meant to support.
Finding a Needle in Haystack: Facebook's Photo Storage

This paper describes Haystack, an object storage system optimized for Facebook's Photos application. Facebook currently stores over 260 billion images, which translates to over 20 petabytes of data. Users upload one billion new photos (∼60 terabytes) each week and Facebook serves over one million images per second at peak. Haystack provides a less expensive and higher performing solution than our previous approach, which leveraged network attached storage appliances over NFS. Our key observation is that this traditional design incurs an excessive number of disk operations because of metadata lookups. We carefully reduce this per photo metadata so that Haystack storage machines can perform all metadata lookups in main memory. This choice conserves disk operations for reading actual data and thus increases overall throughput.
Targeted Mutagenesis of the Hira Gene Results in Gastrulation Defects and Patterning Abnormalities of Mesoendodermal Derivatives Prior to Early Embryonic Lethality

ABSTRACT The Hira gene encodes a nuclear WD40 domain protein homologous to the yeast transcriptional corepressors Hir1p and Hir2p. Using targeted mutagenesis we demonstrate that Hira is essential for murine embryogenesis. Analysis of inbred 129Sv embryos carrying the null mutation revealed an initial requirement during gastrulation, with many mutant embryos having a distorted primitive streak. Mutant embryos recovered at later stages have a range of malformations with axial and paraxial mesendoderm being particularly affected, a finding consistent with the disruption of gastrulation seen earlier in development. This phenotype could be partially rescued by a CD1 genetic background, although the homozygous mutation was always lethal by embryonic day 11, with death probably resulting from abnormal placentation and failure of cardiac morphogenesis.
Affect regulation in depressed and nondepressed children and young adolescents

Abstract The present study examined children's reported frequency and efficacy of strategies for regulating their negative affect in response to a description of a particular affiliative (fight with a friend) or achievement (loss at a game) situation. The 275 children were in kindergarten through eighth grade; they completed the Children's Depression Inventory and either the “Fight” or “Game” version of the Child Affect Questionnaire (CAQ-F or CAQ-G). Children who endorsed higher levels of depressive symptoms generally reported using affect regulation strategies significantly less often than did nondepressed children, and they rated these responses as significantly less effective in altering their negative mood. Depressed girls rated mother-initiated affect regulation strategies as less effective than did nondepressed girls. Younger children rated both self- and mother-initiated strategies as more effective than did older children. Several directions for future research are suggested.
Directors’ and Officers’ Liability Insurance, Corporate Risk and Risk Taking: New Panel Data Evidence on the Role of Directors’ and Officers’ Liability Insurance*

In this paper, we develop and estimate models of the determinants of firms’ demand for directors’ and officers’ liability insurance. We add to and validate the existing empirical literature by testing hypotheses regarding the relationship between D&O insurance purchase and firm size, governance characteristics and business risk. Our data set allows us to test both purchase decisions and limits choices. We present separate estimates of these decisions along with estimates that allow for their joint determination and recognize the potential for selection bias in the estimates of coverage limits models. To shed additional light on the role and consequences of D&O insurance we make additional use of the panel structure of our data to examine the effects of D&O insurance purchase on corporate governance. * Comments and suggestions are welcomed.
