It’s not about what, it’s about who you know: social media-use in organisations

This paper investigates the impact of social media-use on communication processes within organisations. Findings from three qualitative comparative case studies are analysed through the lens of the resource based view of organisations. The analysis follows comparative logic focusing on similarities and differences in case-settings and outcomes. Each of the cases represents an organisation with similar workforces of similar size, composition and distribution but with qualitatively different approaches to social media-use and, as expected, different effects of social media on processes and capabilities. The findings suggest, that the value of social media in contrast to other IT technologies is derived from its use for relationship-building (who actors are connected to and how) rather than information storage and dissemination (what do actors know and where they find it).
Title Towards expressive musical robots : A cross-modal frameworkfor emotional gesture , voice and music

It has been long speculated that expression of emotions from different modalities have the same underlying ‘code’, whether it be a dance step, musical phrase, or tone of voice. This is the first attempt to implement this theory across three modalities, inspired by the polyvalence and repeatability of robotics. We propose a unifying framework to generate emotions across voice, gesture, and music, by representing emotional states as a 4-parameter tuple of speed, intensity, regularity, and extent (SIRE). Our results show that a simple 4-tuple can capture four emotions recognizable at greater than chance across gesture and voice, and at least two emotions across all three modalities. An application for multi-modal, expressive music robots is discussed.
Assumptions of subjective measures of unconscious mental states: higher order thoughts and bias

This paper considers two subjective measures of the existence of unconscious mental states - the guessing criterion, and the zero correlation criterion - and considers the assumptions underlying their application in experimental paradigms. Using higher order thought theory (Rosenthal, e.g. 1986; 1995) the impact of different types of biases oil the zero correlation and guessing criteria are considered. It is argued that subjective measures of consciousness call be biased in various specified ways, some of which involve the relation between first order states and second order thoughts, and hence are not errors in measurement of the conscious status of mental states; but other sorts of biases are measurement errors, involving the relation between higher order thoughts and their expression. Nonetheless, it is argued this type of bias does not preclude subjective measures - both the guessing criterion and the zero correlation criterion - as being amongst the most appropriate and useful tools for measuring the conscious status of mental states.
Age, Cohort, and Wave effects in Japanese Household Consumption † Preliminary Draft (not to be quoted)

Consumer behavior changes with life cycle and generation, as well as with macroeconomic shocks. We estimate Japanese demand systems from the 5 waves of national surveys that cover 21 years (1984 to 2004) by allowing for varying taste parameters and household equivalence scale. Out of 11 broad consumption categories, significant age effects are found in housing, transportation, leisure, education and miscellaneous expenditures. Cohort effects appear in younger age in leisure and transportation but they taper off with age. Housing expenditure is strongly affected by wave effects and shows irregular movement. We propose a method to estimate equivalence scales and implement it. The results indicate that equivalence scale is roughly in between 0.3 and 0.5, a slightly less than the conventional value, and a degree of economy of family scale is decreasing with time.
Genesis, Uses and Environment Implications of Iron Oxides and Ores

Iron oxides are chemical complexes which occur naturally, comprising iron and oxygen. Here, together, 16 types of iron oxides and oxyhydroxides have been identified. These two components of oxides are widely spread naturally. They are vital to humans and useful in most geological and biological activities. In addition, they are useful as pigments and catalyst in industries and hemoglobin in blood circulation. The interplay and conversion of these components from one form to another are essentially controlled by bacterial species. These contain 70 and 72% iron, respectively. Furthermore, iron ores are classified in terms of occurrence. Banded iron formation (BIF) comprises 15% iron, com prising minerals of iron that are bedded besides silica. Beneficiation processes of iron ore generate dust in the atmosphere, acid mine drainage in the ecosystem and metallic iron for steelmaking. Beneficiation process requires dissolution of minerals surrounding the ore and the release of metals and cement matrix into water courses. These generates acid leading to acid mine drainage. Therefore, there is a need for impact assessment of the environment in the planned beneficiation cycle. Sustainable beneficiation must be done to reduce impact on the natural, social or economic environment.
BIOPROSPECTING OF MUNTINGIA CALABURA: BIOACTIVE COMPOUNDS AND ITS ANTIOXIDANT, ANTIMICROBIAL AND ANTHELMENTHIC ACTIVITY.

Objective: Muntingia calabura is widely cultivated and has become one of the common roadside trees in most parts of the world. The present study aimed to evaluate medicinal property of leaves and fruits of M. calabura, by using antioxidant, antimicrobial and antihelmenthic activities for methanol crude extract. Methods: Standard methods were used to evaluate secondary metabolites in methanol crude extract of leaves and fruits of M. calabura. Total phenolic contents (TPC) were evaluated according to Folin-Ciocalteu method. The free radical quenching ability of extracts were explored by various in vitro assays, such as DPPH, hydroxyl radical scavenging and reducing power assay. Additionally, the antimicrobial and anthelminthic activity was conducted to evaluate the biological efficiency of the plant extract. Results: Qualitative phytochemical analysis revealed the presence of alkaloids, saponins, tannins, glycosides, flavonoids and phenols. The reduction of free radical content were observed in dose dependent manner in all tested methods for both leaves and fruits methanol extract of the plant. Further, the antimicrobial activity of plant extract indicates the region where tested microorganisms failed to thrive and the methanol extract also showed evidence to have anthelminthic property. Conclusion: The presence of secondary metabolites and biological activity of methanol crude extract of leaves and fruits of M. calabura ensure the pharmaceutical importance.
Intestinal Herniation into the Right Ventral Abdomen in a Broiler

Abdominal hernias in birds are often not clearly described. A 5-week-old female broiler was presented with a history of abdominal swelling for 3 days followed by sudden death. Herniation in avian species is very rare. Necropsy examination revealed a 5-6 cm sphere-shaped swelling on the right ventral abdomen. On incision of skin, a hernial sac (lined by peritoneal covering) comprising intestinal tract starting from duodenum till caecum was found protruding through an abnormal foramen (about 1-2 cm) of the abdominal muscle into the subcutaneous region of abdominal cavity. Mild congestion of intestinal serosa and mucosal haemorrhages (multifocal) were observed in the hernial sac. The part of pancreas involved in hernia showed multifocal hemorrhage. A cystic dilatation of the mesentery of size 1-2 cm with transparent serous fluid was observed. In the abdominal cavity, intestinal parts (colon and rectum), spleen, kidney and reproductive tract showed mild congestion. Histopathologically, intestinal mucosa revealed moderate hemorrhage, along with inflammation by heterophils, lymphocytes and macrophages. Mesentric fat and Pancreas also revealed mild degree of congestion and haemorrhage. A focal area of liver showed hypertrophied hepatocytes with narrowed sinusoidal space and mild inflammatory infiltrates by heterophils. Feeding of high energy diets to broilers lead to obesity and also serve as a drive for weakness of abdominal muscles by infiltration of fat which would cause gradual stretching of the abdominal musculature, leading to hernia. This case was diagnosed as Intestinal Herniation into the right ventral abdomen in a 5-week-old female broiler.
A computer model of a self replacing beef herd.

The model, shown in Fig. 1, was driven by 16 years of meteorological data from Hamilton, Victoria. The general methods followed those of White (1982) and others at the 1982 conference. The pasture model followed that of Bowman et al. (1982). Three calving dates and seven stocking rates (SR) were simulated (Table 1). Summer calving was prompted by favourable reports (D. Hamilton pers. comm.) in north eastern Victoria. Autumn calving with vealer production is widespread in Victoria. Winter calving seemed likely to increase utilisation of pasture and offer more stability than other systems provided steers were marketed at about 15 months old. Surplus heifers were sold after pregnancy diagnosis, 20 per cent being retained as replacements. Cows were sold when ten years old. In the winter system steers were run at 2.0 per hectare, cows being restricted to the remaining area according to numbers of steers. Animals were divided into classes according to age, physiological status, sex, conception and calving date, and selling policies of each group were those which appeared most appropriate for the production system. Pregnancy rates were estimated from age and live weight in heifers (Axelsen and Morley 1976), and from live weight and liveweight change in cows (Morley et al. 1976).
Spatial variation in the use of seagrass and unvegetated habitats by post-settlement King George whiting (Percoidei: Sillaginidae) in relation to meiofaunal distribution and macrophyte structure

Post-settlement King George whiting Sillaginodes punctata and meiofauna were col- lected from seagrass and unvegetated habitats at 9 sites within Port Phillip Bay, Australia, in October and November 1997. Sites varied considerably in sediment characteristics, macrophyte structure and meiofauna distribution. We hypothesised that the relative use of seagrass and unvegetated habitat by post-settlement S. punctata would vary with the characteristics of sites. Overall, the abundance of S. punctata on seagrass relative to unvegetated habitats varied greatly among sites, ranging from an almost complete association with seagrass to an almost complete association with unvegetated habi- tat. The pattern of habitat use among sites by S. punctata was reflected by the distribution of small crustacea; differences in habitat use across sites for S. punctata and small crustaceans were highly correlated. Relative habitat use across sites by post-settlement S. punctata was also negatively corre- lated with length of seagrass plants. Results suggest a role for prey distribution and seagrass struc- ture in producing these patterns. When data for habitats were pooled, abundance of S. punctata at sites was significantly correlated with meiofaunal crustacean abundance, suggesting that prey distri- bution was an important factor in broad-scale variability in recruitment
Predictable returns in an emerging stock market: Evidence from Qatar

Abstract This article investigates the performance of moving-average strategies and tests the validity of the weak form of the Efficient Market Hypothesis (EMH) for the Qatari Stock Exchange (QSE). This study uses statistical analyses and adopts the version of the variable moving-average rule where buy and sell signals are generated by comparing a share price’s short- and long-term moving averages. The data include the daily closing share prices of 44 Qatari-listed companies for the period 2004–2017. The analysis shows that the QSE is not weak form efficient because patterns and trends are present in share prices. Sectoral analyses suggest that securities in consumer goods and services, industrials and insurance are the most efficiently priced on the QSE. The evidence suggests that profitability depends on the moving-average strategy selected. The findings may thus benefit technical analysts, fund managers, accountants and academics. This study is one of the first to examine the market efficiency of the QSE using trading rules. This research also suggests the possibility of limited transparency and accounting disclosure in the QSE, which may help policy-makers devise regulations that could improve the QSE’s efficiency.

Protein extraction for Cocos nucifera with and without lethal yellowing phytoplasma: gel-based proteomics

Two-dimensional gel electrophoresis (2-DE) is one of the two methodologies to separate and identify gene expression at the proteome level. However, the separation of proteins from plant tissue extract is often complicate, because it is necessary to modify the protocols depending upon the type of tissue and upon the presence of different interfering compounds. In this work it is estab- lished a routine procedure for the application of proteomic analysis to study interaction between palm coconut and lethal yellow- ing (LY) phytoplasma. The characteristics of protocol include: (i) cleanup of pigments and contaminants of the trunk palm coco- nut tissue, using a solution of acetone with TCA and 2-mercaptoethanol. (ii) Phenol extraction of proteins in presence of methanol with ammonium acetate. 2-DE analysis revealed differences in palm coconut with and without LY agent and similitude between palm ecotypes.
Dexmedetomidine attenuates oxidative/nitrative stress in lung tissues of septic mice partly via activating heme oxygenase-1

Excessive reactive oxygen/nitrogen species are considered to be one of the primary events that cause lung injury during sepsis. The present study aimed to determine whether dexmedetomidine (Dex) exhibits antioxidative and antinitrative effects on sepsis-induced lung injury and its effect on heme oxygenase-1 (HO-1) activation. The cecal ligation and puncture (CLP) mouse model was used, where male C57BL/6J mice were randomized into groups: Sham, CLP, Dex and Dex + zinc protoporphyrin (ZnPP). Following CLP or sham operation, intraperitoneal injections of 40 µg/kg Dex or saline were administered in the Dex + ZnPP group, intraperitoneal injections of ZnPP (40 mg/kg) were administered 1 h prior to the CLP operation. Subsequently, histopathological examination of the lungs and measurement of HO-1 activity in the lung, as well as oxidative and nitrative stress were determined 24 h following CLP. Dex significantly decreased the levels of oxidative and nitrative stress, as demonstrated by the decreased levels of malondialdehyde and nitrotyrosine, and the protein expression of inducible nitric oxide synthase, as well as increased superoxide dismutase in lung tissues. Also Dex inhibited the elevation of serum interleukin-6 and tumor necrosis factor-α and increased lung HO-1 activity. Furthermore, the effects of Dex were partially reverted by the HO-1 inhibitor ZnPP. In conclusion, Dex inhibited oxidative/nitrative stress in sepsis and attenuated sepsis-induced acute lung injury partially by increasing HO-1 activity.
Standard tests ability to measure impact forces reduction on mats

Landing is one of the most important and dangerous actions that a gymnast takes. Although landing mats are supposed to meet standard criteria, the number of injuries in this action continues being high, which has raised questions as to the validity of the standard. In this study was analysed the effect of the mat on different kinematical and kinetic variables during gymnast landing, and it was examined the validity of normative tests to predict such variables. 5 elite gymnasts performed several landings on a sample of 6 mats previously selected on the basis of their mechanical behaviour. Maximum vertical reaction forces and peak tibial and forehead acceleration were analysed, with average maximum reaction force of 4450 ± 195.34 N, and 15.57 ± 0.54 g and 4.72 ± 0.55 g on tibial and forehead acceleration respectively. Gymnasts modulate execution based on mat properties, and not all the biomechanical variables studied are faithfully reproduced in the mechanical tests of the standard, which could have some influence on the occurrence of certain injuries.
Evaluation of fluorescence measurement techniques for tumour detection in vivo

We investigated the influence of tumour depth and differences in blood concentration and autofluorescence between tumour and normal tissue on the fluorescence of a tumour-localising agent. Carotenoporphyrin, CP(Me)3, was injected into rats and nude mice with intradermal tumours. On the tumours an incision was made, uncovering 2 mm" of the tumour, and fluorescence measurements, including excitation-emission maps and fluorescence ratios, were made on skin, covered and uncovered tumour. The measured fluorescence ratio in the uncovered tumour showed a threeto tenfold increase compared to the covered tumour. We used one-dimensional layered tissue to analyse the data. In conclusion, even with a high tumour-selectivity deeper lying tumours cannot always be detected, particularly if the tumour has a high blood concentration or low autofluorescence intensity.
The formation of a subsurface anticyclonic eddy in the Peru‐Chile Undercurrent and its impact on the near‐coastal salinity, oxygen, and nutrient distributions

The formation of a subsurface anticyclonic eddy in the Peru-Chile Undercurrent (PCUC) in January and February 2013 is investigated using a multi-platform four-dimensional observational approach. Research vessel, multiple glider and mooring-based measurements were conducted in the Peruvian upwelling regime near 12°30'S. The dataset consists of > 10000 glider profiles and repeated vessel-based hydrography and velocity transects. It allows a detailed description of the eddy formation and its impact on the near-coastal salinity, oxygen and nutrient distributions. In early January, a strong PCUC with maximum poleward velocities of ∼ 0.25 m/s at 100 to 200 m depth was observed. Starting on January 20 a subsurface anticyclonic eddy developed in the PCUC downstream of a topographic bend, suggesting flow separation as the eddy formation mechanism. The eddy core waters exhibited oxygen concentrations < 1μmol/kg, an elevated nitrogen-deficit of ∼ 17μmol/l and potential vorticity close to zero, which seemed to originate from the bottom boundary layer of the continental slope. The eddy-induced across-shelf velocities resulted in an elevated exchange of water masses between the upper continental slope and the open ocean. Small scale salinity and oxygen structures were formed by along-isopycnal stirring and indications of eddy-driven oxygen ventilation of the upper oxygen minimum zone were observed. It is concluded that mesoscale stirring of solutes and the offshore transport of eddy core properties could provide an important coastal open-ocean exchange mechanism with potentially large implications for nutrient budgets and biogeochemical cycling in the oxygen minimum zone off Peru.
Sediment deposition and movement over a turf assemblage in a shallow rocky coastal area of the Ligurian Sea

The depositional environment over a turf assemblage of the rocky shore south of Livorno was studied from April 1992 to September 1993 by means of sediment traps positioned 50 and 200 cm above the turf surface. Changes in environmental conditions and in the intensity of terrestrial erosion and wind-wave resuspension of bottom sediments played a major role in controlling both the magnitude of sediment deposition and the nature of sedimented material, while limited responses to seasonal patterns of sedimentation of phytoplanktonic material were found. Mean rates of sediment deposition fluctuated between 1.6 and 52.4 g m-' d-', and the amount of trapped material decreased with distance from bottom, reflecting intense sediment resuspension and movement over the algal turf. The material sedimenting was mostly composed of small-size (<ZOO pm) inorganic particles, and the organic material was characterized by the presence of highly degraded detritus. Besides faecal pellets few recognizable structures were found in the traps, such as charcoal fragments which probably originated from extensive burning of the coastal vegetation. Considerable variations in the intensity of the depositional environment over the algal turf were evident: the maxima sediment deposition and movement occurred in autumn and were related to heavy rainfall and wind-wave action, while in the summer the algal turf was generally free from sediment smother and scour. The ecological significance of these quantitative and qualitative temporal fluctuations is discussed, and the possible long-terrp impact of fire deforestation and increased soil erosion on turf structure and composition is hypothesized.
Tomography of fast-ion velocity-space distributions from synthetic CTS and FIDA measurements

We compute tomographies of 2D fast-ion velocity distribution functions from synthetic collective Thomson scattering (CTS) and fast-ion Dα (FIDA) 1D measurements using a new reconstruction prescription. Contradicting conventional wisdom we demonstrate that one single 1D CTS or FIDA view suffices to compute accurate tomographies of arbitrary 2D functions under idealized conditions. Under simulated experimental conditions, single-view tomographies do not resemble the original fast-ion velocity distribution functions but nevertheless show their coarsest features. For CTS or FIDA systems with many simultaneous views on the same measurement volume, the resemblance improves with the number of available views, even if the resolution in each view is varied inversely proportional to the number of views, so that the total number of measurements in all views is the same. With a realistic four-view system, tomographies of a beam ion velocity distribution function at ASDEX Upgrade reproduce the general shape of the function and the location of the maxima at full and half injection energy of the beam ions. By applying our method to real many-view CTS or FIDA measurements, one could determine tomographies of 2D fast-ion velocity distribution functions experimentally.
Monitoring of excessive deformation of steel structure Extra-High Voltage pylons

Reliability and security of a power transmission depends on the state of the power grid and mainly on the state of the ExtraHigh Voltage pylons. The paper deals with deformation analysis of existing steel structure of selected Extra-High Voltage pylons which showed excessive differences comparing to the original design. In the assessment of the situation, geodetic survey of selected pylons of power grid that showed the greatest deformation was performed. On taken images, deformation of steel structures by using the FOTOMNG system was also analyzed. The proposed method allows a modeling of the structure of the object based on precisely obtained photographic documentation of the current state. It also represents a very effective method which allows to quickly and efficiently analyze the deformation in the structure of Extra-High Voltage pylons in the critical position of the power grid. Other benefits include the possibility of repeatable and safe measurement.
