Mind the Gap : Adapting and Reorienting Organizational Architectures

The study of organizational architecture builds upon the analysis of the different answers provided by organizations to increase the fit with their external environment. Investigating such theme, scholars emphasize the evolutionary nature of firms in terms of adaptation, flexibility, evolution and decomposability: firms combine and recombine elements that compose its architecture, modifying them in a number of different ways. In the present work we examined how the organization modifies its architecture in response to environmental feedback, measured in terms of performance gap. In a study of 755 organizations, we found that, depending on the presence of a performance gap, the organization decides whether to maintain its current architecture or to modify it. Interestingly, the extension of the performance gap affects the magnitude of organizational architectural change: on the basis of the extension of the performance gap, the organization will implement either minor or major modifications in its architecture.
MANAGEMENT OF RESISTANT Conyza spp . DURING SOYBEAN PRE-SOWING Manejo

Horseweed (Conyza spp.) is a weed with a considerable presence and frequency throughout Brazilian crops, as well as presenting difficult chemical control. The objective of this study was to evaluate the efficiency of herbicide management, through single and sequential applications, in controlling Conyza spp. , at two development stages with 4 to 6 leaves (3 to 5 cm) and 20 leaves (15-20 cm). The analyzed variables were: control percentage (7, 14, 21, and 28 days after application), dry matter content (28 days after application) and regrowth percentage (21 days after application). Data were submitted to analysis of variance at 5% probability and when there was a difference, the means were submitted to the Scott-Knott test. For Conyza spp. plants with a height between 3 and 5 cm and 4 to 6 leaves, the best treatments were T4, T8, T9, T10, T11, T12, T13, and T14, presenting a control percentage above 90%, 7 days after application. For Conyzaspp. plants with a plant development of 15 cm in height and 15 to 20 leaves, the highest control percentages and lowest regrowth percentages were with treatments T9, T13, and T14.
Inhibition of Gastric Acid Secretion by H 2 Receptor Antagonists Associates a Definite Risk of Enteric Peritonitis and Infectious Mortality in Patients Treated with Peritoneal Dialysis

Evidences linking treatment with inhibitors of gastric acid secretion (IGAS) and an increased risk of serious infections are inconclusive, both in the population at large and in the particular case of patients with chronic kidney disease. We have undertaken an investigation to disclose associations between treatment with IGAS and infectious outcomes, in patients undergoing chronic Peritoneal Dialysis (PD).
Extracting Character Networks to Explore Literary Plot Dynamics

In this paper we apply network analysis to the study of literature. At the first stage of our investigation we automatically extract networks (graphs) of characters for each part of Leo Tolstoy’s novel War and peace using two different techniques for network creation. Then we evaluate these two techniques against a set of manually created gold standard networks. Finally, we use the method that demonstrated better performance in our evaluation to test a literary hypothesis about Tolstoy’s novel. The hypotheses we intended to prove was that the parts of the novel describing war (i.e. those where the battlefield or military units are the primary settings), have statistically lower density of interaction between characters, resulting in lower network density, higher network diameters and lesser average node degrees. By showing this correlation we mean to demonstrate the applicability of network analysis to computational research of fictional narrative (e.g. detection of tension changes in the plot).
UC Office of the President Recent Work Title Network Analysis of Protein Adaptation : Modeling the Functional Impact of Multiple Mutations Permalink

The evolution of new biochemical activities frequently involves complex dependencies between mutations and rapid evolutionary radiation. Mutation co-occurrence and covariation have previously been used to identify compensating mutations that are the result of physical contacts and preserve protein function and fold. Here, we model pairwise functional dependencies and higher order interactions that enable evolution of new protein functions. We use a network model to find complex dependencies between mutations resulting from evolutionary trade-offs and pleiotropic effects. We present a method to construct these networks and to identify functionally interacting mutations in both extant and reconstructed ancestral sequences (Network Analysis of Protein Adaptation). The time ordering of mutations can be incorporated into the networks through phylogenetic reconstruction. We apply NAPA to three distantly homologous b-lactamase protein clusters (TEM, CTX-M-3, and OXA-51), each of which has experienced recent evolutionary radiation under substantially different selective pressures. By analyzing the network properties of each protein cluster, we identify key adaptive mutations, positive pairwise interactions, different adaptive solutions to the same selective pressure, and complex evolutionary trajectories likely to increase protein fitness. We also present evidence that incorporating information from phylogenetic reconstruction and ancestral sequence inference can reduce the number of spurious links in the network, whereas preserving overall network community structure. The analysis does not require structural or biochemical data. In contrast to function-preserving mutation dependencies, which are frequently from structural contacts, gain-of-function mutation dependencies are most commonly between residues distal in protein structure.
Cyclic-di-adenosine monophosphate (c-di-AMP) is required for osmotic regulation in Staphylococcus aureus but dispensable for viability in anaerobic conditions

Cyclic di-adenosine monophosphate (c-di-AMP) is a recently discovered signaling molecule important for the survival of Firmicutes, a large bacterial group that includes notable pathogens such as Staphylococcus aureus . However, the exact role of this molecule has not been identified. dacA , the S. aureus gene encodingthediadenylatecyclaseenzymerequiredforc-di-AMP production, cannot be deleted when bacterial cells are grown in rich medium, indicating that c-di-AMP is required for growth in this condition. Here, we report that an S. aureus dacA mutant can be generated in chemically defined medium. Consistent with previous findings, this mutant had a severe growth defect when cultured in rich medium. Using this growth defect in rich medium, we selected for suppressor strains with improved growth to identify c-di-AMP–requiring pathways. Mutations bypassing the essentiality of dacA were identified in alsT and opuD, encoding a predicted amino acid and osmolyte transporter, the latter of which we show here to be the main glycine betaine–uptake system in S. aureus. Inactivation of these transporters likely prevents the excessive osmolyte and amino acid accumulation in the cell, providing further evidence for a key role of c-di-AMP in osmotic regulation.

Exploring the importance of coaches in the development of the sports career in Handball . The perception of athletes from higher and lower levels of success

Our study investigated the perception of elite handball players, belonging to national teams who during the early stages of their career had similar success rates but with different levels of success at the senior level, on how they characterize their most important club and national team coach. Fourteen athletes were interviewed based on the protocol of Gould, Dieffenbach and Moffett (2002). In the specialization years (Bloom, 1985), the most successful athletes reported that they had one coach in the club, and a national team coach, that permanently marked their sports career and their personality. According to them, their reference coaches taught directly and indirectly (caring, paying individual attention), emphasized expectations, discipline and the attitude that hard work pays off. It is concluded that the coach seems to play a determining role in the development of the athletes, thus highlighting the importance of promoting and strengthening the quality of their education.

EFFECTS OF Zn AND Al ON CORROSION CHARACTERISTICS OF Sn-1.0Ag-0.5Cu ALLOYS NURUL LIYANA BINTI KAMARUZAMAN FACULTY OF ENGINEERING UNIVERSITY OF MALAYA

In the past few years, tin-lead (Sn-Pb) solder alloys had been popularly used in the electronic industries especially in packaging. However, lead and lead containing alloys have been banned because of environmental and health concerns. Recently, efforts are being made to develop a usable lead-free solder to substitute tin-lead based solder alloys. Comparing to other solders, tin-silver-copper (Sn-Ag-Cu) free solder alloys seem to be the best alternative to replace traditional lead-tin based solder alloys. In the present study, the corrosion characteristics of lead-free solder alloys such as Sn-1.0Ag-0.5CuXZn (X= 0, 0.1, 0.5. 1.0) and Sn-1.0Ag-0.5Cu-XAl (X=0, 0.1, 0.5, 1.0) have been investigated in 3.5wt-% NaCl solution. The corrosion behavior of were studied through Polarization curve and the Electrochemical Impedance Spectroscopy (EIS) by using Gamry Echem Analyst DC105 software. The microstructure and element of the corrosion compounds formed on the surface of lead-free solder alloys were investigated by Scanning Electron Microscopy (SEM), Energy-dispersive X-ray Spectroscopy (EDX), and X-ray Diffraction (XRD). The polarization curves showed that the addition of Zn in SAC105 solder alloy increased the corrosion current density and shifted the corrosion potential towards more negative values. As a result, the corrosion resistance of Sn-1.0Ag-0.5Cu-XZn alloys reduces with the increase of Zn concentration. The EIS results agreed well with the findings obtained from polarization curves. The corrosion products at the surface of the investigated Zn doped alloys constituted of Sn3O(OH)2Cl2, SnO, SnO2 and ZnO. Like Zn, addition of Al also decreases the corrosion resistance of the SAC 105 solder alloy.

Finnish teachers’ perceptions on distributed leadership: resource and agency

Applying the resource–agency du ality model, this paper examines Finn ish teachers’ perceptions on distributed leadership. A total of 203 comprehen sive and secondary school teachers re sponded to an online survey that inves tigated the following aspects within the Finnish school context: leadership struc tures and power distance, leadership as a resource, leadership as an agency, and motivators and demotivators underly ing teachers’ participation in leader ship tasks. The survey results showed that Finnish schools did not have a one common leadership structure. The resource and agency distributions showed both alignment and misalignment. In particular, the misalignment was man ifested in the tight school budgets, local educational policies, and national educational laws whose impact the Finnish teachers wanted to decrease. Meanwhile, the teachers wanted to exercise strong er agency together with mid-level team leaders and students. Time, financial resources, and trust were identified as the most powerful driving force behind distributed leadership. Teachers were motivated to lead if the tasks matched their expertise and did not disturb their teaching. In contrast, leadership titles or assigning administrative tasks were less effective in promoting distribut ed leadership among Finnish teachers.
Factors Influencing FDI Inflows to Developing Countries

Many studies have found that foreign direct investment (FDI) can play a positive role in spurring economic growth and income of host countries. FDI can take the form of investment in new assets (greenfield investment) or acquisition of existing assets (mergers and acquisitions; M&A). Because of their distinctive characteristics, the two FDI modes may have different effects. This paper empirically evaluates how institutional and policy factors influence greenfield and M&A investments to developing countries. For this purpose, this paper utilizes bilateral greenfield and M&A investments for the period 2003-2014. We offer a number of new findings. Among the three sets of host country-specific factors, we find that the quality of local governance is the most important factor for both greenfield and M&A investments to developing countries, whereas FDI restrictive policies of developing countries are not significant factors in restricting FDI inflows to these countries. We also find that an improvement in host country’s environment for doing business may have a positive effect on greenfield investment only when the host country’s governance quality is very low. Among the pair-specific policy factors, regional trade agreements have a significantly positive impact on greenfield investment flows to developing countries, while bilateral investment treaties do not exert any positive effect either on greenfield investment or M&A investment. + A paper prepared as input to the Asian Development Bank (ADB)’s Asian Economic Integration Report 2016.

A NEW CHANNEL IN THE HOUSING MARKET CYCLE November 24 , 2017

Demographic and institutional elements as important drivers of the housing market should not be neglected since it is not only financial and monetary elements that matter in the case of the housing market. In this context, one relationship, which still remains unclear, is the relationship between the housing and the labour markets. Some research has been undertaken to support the hypothesis that high rates of homeownership lead to high unemployment via increases in the reservation wage. However, further research is needed to address the possible implications of the institutional settings of the labour market in the dynamics of the housing market. The aim of this paper is to bring some light on the link between both markets. In particular, this contribution explains how the housing cycle could be ‘amplified’ via a new channel, i.e. economic precariousness, which is closely related to job insecurity. Subsequently, we provide evidence in the case of five developed economies, Ireland, the Netherlands, Spain, the United Kingdom and the United States, over the period 1985-2013. 1 University of Cambridge, UK, FMM Fellow. 2 Ecorys, The Netherlands. —————————
Symptoms of posttraumatic stress , quality of life and post-traumatic growth among cancer patients and survivors : The role of psychological flexibility U C / F P C

Cancer is often considered a traumatic event and may encompass the experience of symptoms of posttraumatic stress, which may compromise the patient’s well-being over the course of illness and beyond. These symptoms can hamper patients’ emotional regulation, leading to psychological distress and worsening their perception of quality of life (QoL). Nevertheless, these symptoms have also been associated with posttraumatic growth (PTG) among cancer survivors, highlighting the different possibilities of adjustment that can emerge after a traumatic event. In this context, the aim of this study was to examine the role of psychological flexibility, a key variable in mental health promotion, in the association between symptoms of posttraumatic stress, QoL and PTG, among cancer patients and survivors. The sample of this cross-sectional study consisted of 73 participants, one group of cancer patients in treatment (n = 39) and one group of cancer survivors (n = 34). Participants completed self-reported questionnaires assessing symptoms of traumatic stress (PCL-C), psychological flexibility (AAQII), quality of life (WHOQOL-Bref), and posttraumatic growth (PTGI-SF). The results of this study showed that symptoms of traumatic stress were associated with reduced QoL, however, they were not significantly associated with PTG. Psychological flexibility was significantly associated with QoL, but not with PTG. The moderation of psychological flexibility was not significant. A moderated moderation was found, which indicated a significant moderation of the disease stage in the association between symptoms of posttraumatic stress, psychological flexibility and overall QoL, among cancer patients. The results of this study reiterate the usefulness and purposefulness of psychological flexibility as a health promoting variable, considering its association with better QoL. A special attention should be given to this variable among cancer patients, particularly because of its moderating role in the association between symptoms of traumatic stress and overall QoL.
Does r − g cause wealth inequality ?

Piketty claims that the gap between the return to capital and the growth rate (r−g) governs the evolution of wealth inequality. This paper assesses its empirical validity using an IV approach and almost one century of US data. Our results are twofold: First, wealth shares are nonstationary, necessitating first differences to draw valid inference from any econometric exercise. This is consistent with Piketty’s line of argumentation and casts doubt on studies on inequality that use inequality levels without showing the trending behavior of the data. Second, r−g played a significant role in the evolution of wealth inequality over the last century, both statistically and economically. In particular, r − g can explain over 50% of the increase in wealth inequality since the late 1970s.
Highly branched isoprenoids for Southern Ocean sea ice reconstructions: a pilot study from the Western Antarctic Peninsula

Abstract. Organic geochemical and micropaleontological analyses of surface sediments collected in the southern Drake Passage and the Bransfield Strait, Western Antarctic Peninsula, enable a proxy-based reconstruction of recent sea ice conditions in this climate-sensitive area. We study the distribution of the sea ice biomarker IPSO25, and biomarkers of open marine environments such as more unsaturated highly branched isoprenoid alkenes and phytosterols. Comparison of the sedimentary distribution of these biomarker lipids with sea ice data obtained from satellite observations and diatom-based sea ice estimates provide for an evaluation of the suitability of these biomarkers to reflect recent sea surface conditions. The distribution of IPSO25 supports earlier suggestions that the source diatom seems to be common in near-coastal environments characterized by annually recurring sea ice cover, while the distribution of the other biomarkers is highly variable. Offsets between sea ice estimates deduced from the abundance of biomarkers and satellite-based sea ice data are attributed to the different time intervals recorded within the sediments and the instrumental records from the study area, which experienced rapid environmental changes during the past 100 years. To distinguish areas characterized by permanently ice-free conditions, seasonal sea ice cover and extended sea ice cover, we apply the concept of the PIP25 index from the Arctic Ocean to our data and introduce the term PIPSO25 as a potential sea ice proxy. While the trends in PIPSO25 are generally consistent with satellite sea ice data and winter sea ice concentrations in the study area estimated by diatom transfer functions, more studies on the environmental significance of IPSO25 as a Southern Ocean sea ice proxy are needed before this biomarker can be applied for semi-quantitative sea ice reconstructions.

EARLY DETECTION OF COBWEB DISEASE INFECTION ON AGARICUS BISPORUS SPOROCARPS USING HYPERSPECTRAL IMAGING

From the nineteen-nineties, cobweb disease caused serious losses for the mushroom sector in Europe, in the USA, and in Australia (FLETCHER & GAZE, 2008), so it is one of the most notable fungal infections of cultivated white button mushroom (Agaricus bisporus). The aim of this study was to identify cobweb disease (Cladobortyum dendroides) caused cap spotting and brownish rot on the mushroom sporocarp, and to fi nd a proper discrimination method in the case of this infection. Fruiting body samples were divided into 4 groups, a control one and three others treated with different chemicals that are tested against fungal infections. The groups were subdivided into 2 portions and the fi rst was infected with cobweb disease. Images of the caps were recorded and their hyperspectral images were acquired in the wavelength range of 900–1700 nm. On the hyperspectral images infected and healthy areas were selected, on these average spectra differences were found around the known water peaks (1200 and 1450 nm). The spatial distribution of the water content can be used for the detection of the spoilage, because the infected areas showed different refl ection values at these water absorption peaks. Support Vector Machine method was applied successfully to discriminate between the infected and control groups and Monte Carlo cross-validation was carried out.
