Spatial and linear correlations between soil and corn

The Technologies setting at Agricultural production system have the main characteristics the vertical productivity, reduced costs, soil physical, chemical and biological improvement to promote production sustainable growth. Thus, the study aimed to determine the variability and the linear and special correlations between the plant and soil attributes in order to select and indicate good representation of soil physical quality for forage productivity. In the growing season of 2006, on the Fazenda Bonanca in Pereira Barreto (SP), the productivity of autumn corn forage (FDM) in an irrigated no-tillage system and the soil physical properties were analyzed. The purpose was to study the variability and the linear and spatial correlations between the plant and soil properties, to select an indicator of soil physical quality related to corn forage yield. A geostatistical grid was installed to collect soil and plant data, with 125 sampling points in an area of 2,500 m2. The results show that the studied properties did not vary randomly and that data variability was low to very high, with well-defined spatial patterns, ranging from 7.8 to 38.0 m. On the other hand, the linear correlation between the plant and the soil properties was low and highly significant. The pairs forage dry matter versus microporosity and stem diameter versus bulk density were best correlated in the 0-0.10 m layer, while the other pairs - forage dry matter versus macro - and total porosity - were inversely correlated in the same layer. However, from the spatial point of view, there was a high inverse correlation between forage dry matter with microporosity, so that microporosity in the 0-0.10 m layer can be considered a good indicator of soil physical quality, with a view to corn forage yield.
Subsampling-Based Tests of Stock-Return Predictability

We develop subsampling-based tests of stock-return predictability and apply them to U.S. data. These tests allow for multiple predictor variables with local-to-unit roots. By contrast, previous methods that model the predictor variables as nearly integrated are only applicable to univariate predictive regressions. Simulation results demonstrate that our subsampling-based tests have desirable size and power properties. Using stock-market valuation ratios and the risk-free rate as predictors, our univariate tests show that the evidence of predictability is more concentrated in the 1926-1994 subperiod. In bivariate tests, we find support for predictability in the full sample period 1926-2004 and the 1952-2004 subperiod as well. For the subperiod 1952-2004, we also consider a number of consumption-based variables as predictors for stock returns and find that they tend to perform better than the dividend-price ratio. Among the variables we consider, the predictive power of the consumption-wealth ratio proposed by Lettau and Ludvigson (2001a, 2001b) seems to be the most robust. Among variables based on habit persistence, Campbell and Cochrane's (1999) nonlinear specication tends to outperform a more traditional, linear specification.
The long term effects of social deprivation on black-capped capuchins (Sapajus apella) rescued from the primate pet trade

Captivity is often physicallyand psychologically damaging to primates, who have complex ethological and social needs. It is widely agreed that primates do not make suitable domestic pets, however it is still legal to keep some species of primates as pets in the UK.The effects of theexotic pet trade on primate welfare arepoorly documented.Itis extremely likely that it will bedetrimental towards their physical and mental health, especially when kept in isolation fromother primates, but there is little evidence to show the long-term implicationsof social deprivation.This studyobserved the long term-effects of social isolation on black-capped capuchins (Sapajus apella) rescued from the pet trade. Five individuals that were kept in social isolation whilst they were a pet(Isolation condition) were compared tofive individuals that were kept in social groups(Social condition). There was a significant differencebetween the frequenciesof abnormal behaviours between the two housing conditions(P =0.008). Individuals in the Isolation condition performedmore abnormal behaviours than the individuals in the Social condition. There was also a significant difference in the frequencies offeeding (including foraging) behaviours(P =0.032),with the Social condition showingmuch higher frequencies offeeding behaviours than the Isolation condition.These results emphasisethe importance of appropriate social housing forprimates in the pet trade, as years of social rehabilitation have evidently not abolished theseabnormal behaviours that originatedfrom being kept in social isolation as pets. Furthermore, it reiterates that primates are not suitable pets as most environments cannot suitably meet their complex ethological and social needs.
Key customer engagement drivers in social media

The rapid development of Internet technologies and pervasive spread of social media in the last decade have led to a tremendous growth of interest in customer engagement (CE). Nowadays, social media significantly enrich and facilitate marketing communications and enable brands to get closer to their customers, serve them and engage as never before. At the same time, social media allow customers to be active and often to play a leading role in their relationships with brands. CE in social media is a complex and challenging task, which requires companies to have a clear vision of motivational drivers that lead customers toward engagement with brands. Moreover, the development and implementation of effective customer engagement strategies in practice is difficult without an understanding of how social media influence customers’ attitudes and behaviors. This research identified and analyzed fourteen key customer engagement drivers (KCEDs) in social media. Additionally, a new conceptual framework for KCEDs was developed. The framework presents gratification and positive emotions; utilitarian; and social groups of drivers that take place in the brand-to-customer and customer-tocustomer contexts. The proposed framework is aimed at enhancing the understanding of online CE and its motivational origins as well as providing the foundation that facilitates designing effective CE strategies in social media. In addition to a review of marketing and persuasive technology academic literature, twelve interviews with marketing and communication professionals were conducted in order to provide an empirical insight into the phenomenon of CE in social media. The findings of the empirical part indicate that a thorough analysis of the persuasion context helps companies in selecting the proper social media channels for CE activities; designing an appropriate persuasion message; and determining a suitable route of persuasion depends on the industry of a brand, the type of marketing relationship, and the target audience. The findings prove that customers consider social media as trustworthy sources of brand-related information and highly value their openness. Also, the empirical results verify the reliability of the theoretical finding and demonstrate that effectiveness of KCEDs in social media may vary in different countries.
Individual Decision-Making to Commit a Crime: Early Models

The authors provide the summary of the most important findings of the early models of economics of crime, namely the models of Becker, Ehrlich and Heineke. These models study rational individual decision-making about entering into illegal activities. Probability and siže of punishment, attitudes towards risk, gains form crime and income are the main variables which causes the results of the individual behavior. The authors also discuss weaknesses of these models such as its static nature or ignoring interactive decision-making. The relationship to the theory of optimal law enforcement is also presented.
Vertical migration behaviour in the larvae of the shore crab Carcinus maenas from a microtidal system (Gullmarsfjord, Sweden)

Tide-related vertical migration behaviours which assist in horizontal transport of marine larvae have been documented in many species from meso-tidal systems; however, little is known about larval behaviour in areas where the tides do not produce predictable changes in water cur- rents. We assessed the vertical migration behaviour in larvae of the shore crab Carcinus maenas (L.) from the Swedish west coast, to explore possible transport mechanisms in a micro-tidal system. Repli- cated plankton samples were collected at a fixed station from 2 depths during flood and ebb tides, and analysed for effects of tides and light on temporal and vertical patterns in abundance. In a com- plementary experiment, first-stage zoeae were hatched in the laboratory from field-collected females and studied in constant darkness for endogenous circa-tidal or circa-diel rhythms. The abundance of different larval stages decreased from the first to the fourth zoeal stage by a factor 10, whereas mega- lopal densities were similar to those of the first zoea. This pattern in abundance indicates an off- shore/onshore transportation of larvae during ontogeny, suggesting a behavioural component in larval dispersal. However, contrary to what has been demonstrated in larvae from meso-tidal areas, none of the larval stages displayed a vertical or temporal pattern in abundance related to the tide, although a clear semi-diurnal tidal change of approximately 0.3 m was registered throughout the sampling periods. Instead, the highest densities of all larval stages were consistently sampled during low light conditions, indicating a diel pattern in swimming behaviour. This behaviour appears to be controlled by exogenous cues, since the laboratory experiment with first zoeae in constant darkness did not indicate any consistent tidal or diel rhythm in vertical migration. The lack of an endogenous circa-tidal vertical migration rhythm suggests that Swedish shore crabs are reproductively isolated from the British Isles populations, where this behaviour has been demonstrated to be inherited. The possibility that C. maenas larvae in micro-tidal systems may use predictable sea and land breezes as a mechanism for cross-shelf transport is discussed.
Impact of the Customer Relationship Management on the Performance of the Institutions of Microfinance in Cameroon: The Case of the CAMCCUL Network

The objective of this contribution is to work out the customer relationship management and the commercial performance of the institutions of microfinance (IMF) in Cameroon in order to show its impacts on the performance indicators of the latter. To achieve this goal, we have simultaneously applied the nonparametric method of the Data Envelopment Analysis (DEA) and the censored Tobit model on a sample of 60 IMF belonging to the Cameroon Cooperative Credit Union League (CAMCCUL) network. The different statistical tests carried out have first of all permitted us to estimate the IMF performance levels and then to assess the different factors which influence the commercial performance of the IMF, taking into account the indicators obtained from the literature review. As a general rule, we have realized from our results that the IMF of the CAMCCUL network are globally inefficient as regards the commercial performance, the women influence on the scores of performance being very significant, insofar as the IMF which are in majority made up of women have relatively been more impressive compared to those which are in majority made up of men. Among the factors influencing the performance, we have noted that the computerized management of the customer relationship and the proximity (closeness) of the social contacts exert a positive influence on the performance, while the satisfaction towards the past experiences with the IMF exerts a negative and very significant influence on this one.
Motivation as a Mediator of Social Disparities in Academic Achievement

The present study aimed at contributing to the understanding of social disparities in relation to students‘ academic achievement in the science, technology, engineering and mathematics domains. A sample of n = 321 German 11th graders completed measures of their family socio–economic status (SES), general intelligence, domain–specific ability self–concepts and subjective scholastic values in math, physics and chemistry. Students‘ grades in these subjects received four months after testing served as criteria. Significant mediation effects were found for all motivational variables between fathers‘ SES and students‘ achievement, whereas for mothers‘ SES, only children's academic self–concept in chemistry was a significant mediator. These results also held when students‘ general intelligence was controlled. Additionally, we controlled for students‘ grades before testing to investigate which variables mediated the influence of SES on change in school performance. Motivational variables significantly mediated the influence of fathers‘ SES on change in school performance in math but not in chemistry and physics. Intelligence significantly mediated the influence of fathers‘ SES on change in school performance in physics and chemistry but not in mathematics. The impact of mothers‘ SES on change in grades in chemistry was mediated by intelligence. Among others, the reasons potentially accounting for the differential influences of fathers‘ and mothers‘ SES are discussed. Copyright © 2011 John Wiley & Sons, Ltd.
Petrology and geochemistry of chert on the marginal zone of Yangtze Platform, western Hunan, South China, during the Ediacaran–Cambrian transition

The Ediacaran–Cambrian transition was one of the most critical intervals in Earth history. During this interval, widespread chert was precipitated, commonly as a stratal wedge in carbonates, along the southern margin of the Yangtze Platform, South China. The chert wedge passes into a full chert succession further basinward to the south‐east. Four lithotypes of chert are identified across the marginal zone in western Hunan: mounded, vein, brecciated and bedded chert. The mounded chert is characterized by irregular to digitiform internal fabrics, generally with abundant original vesicles and/or channels that mostly are lined by botryoidal chalcedony cements with minor quartz and barite crystals. The host chert (or matrix) of these mounds is dominated by amorphous cryptocrystalline silica, commonly disseminated with pyrite. The vein chert, with minor quartz locally, generally cross‐cuts the overlying dolostone and chert horizons and terminates under the mounded and/or bedded chert bodies. The brecciated chert commonly occurs as splayed ‘intrusions’ or funnel‐shaped wedges and cross‐cuts the topmost dolostones. The bedded chert, the most common type, generally is thin to medium‐bedded and laminated locally; it is composed of amorphous silica with minor amounts of black lumps. Microthermometry of fluid inclusions from vein and void‐lining minerals (mainly quartz and barite) revealed homogenization temperatures from 120 to 180°C for the trapped primary fluids. Compositionally, these chert deposits generally are pure, with SiO2 > 92 wt%, and only minor Fe2O3 and Al2O3 contents, most of which show positive Europium anomalies in rare earth element patterns, especially for the mounded chert. All these data suggest that the marginal zone chert deposits resulted from a low‐temperature, silica‐rich hydrothermal system, in which the mounded chert was precipitated around the releasing vents, i.e. as silica chimneys. The vein and splayed brecciated chert, however, was formed along the syndepositional fault/fracture conduits that linked downward, while the bedded chert was precipitated in the quieter water column from the fallout of hydrothermal plumes onto the sea floor. These petrological and geochemical data provide compelling evidence and a new clue to the understanding of the extensive silica precipitation; rapid tectono‐depositional and oceanic changes during the Ediacaran–Cambrian transition in South China.
Graphene oxide reinforced polylactic acid/polyurethane antibacterial composites

Nanocomposites from PLA/PU containing small concentrations of graphene oxide (GO) were prepared by simple liquid-phase mixing followed by casting. The as-prepared ternary PLA/PU/GO composite films exhibited good antibacterial activity against the gram-positive Staphylococcus aureus and the gram-negative Escherichia coli, due to the excellent antibacterial property of GO sheets with high specific surface area. The addition of GO inhibited the attachment and proliferation of microbes on the film surfaces, resulting in that the PLA/PU/GO composite films show remarkably improved antibacterial activity compared with PLA/PU composite film. The inhibition efficiency is proportional to the amount of GO. Furthermore, PLA/PU/GO composite fibrous paper was fabricated using electrospinning and exhibited good biocompatibility. The addition of GO does not destroy normal cell's proliferation and differentiation. PLA/PU/GO composites with good antibacterial activity and biocompatibility make it attractive for the environmental and clinical applications and also provide a candidate for future application of tissue engineering.
Retail employees' experiences of organisational culture

Title: Retail employees' experience of organisational culture. Key terns: Retail, employees, organisational culture, change. During the 1980's the focus on corporate culture had received revived attention. The key to corporate success was a strong unified culture and it soon became a secret weapon to gain a competitive advantage. Aligning corporate culture to the organisation's strategy is crucial in enabling organisations to respond to the rapid and ever-changing internal and external demands. Organisational culture is considered the glue that keeps an organisation together due to the impact of the culture on the organisation's survival. The objective of this research was to determine how employees experience organisational culture and how it manifests within a retail organisation. A purposive (n = 13) was taken of managers on different managerial levels within a South African retail company. All participants attended a strategic leadership intervention that was implemented. Data gathering was conducted by means of interviews based on the phenomenological approach. The interviews were transcribed and data analysis was carried out by means of content analysis. The results showed that the old culture of the organisation was typified by the power and role cultures as identified by Harrison and Stokes, whilst the new culture is typified by a move towards the performance culture with some elements of the support culture. The management style in the old culture was very autocratic with closed lines of communication. People relationships were formal and the focus was on individualism, where people were not regarded in the organisation. The new culture is very people focused and people feel a sense of belonging. There is a culture of continuous learning and there is a move towards collectivism. People live the values of the organisation. Age, race, gender or years of service in the company did not significantly influence employees' experiences of organisational culture. There were no significant differences in the cultural experiences of employees on different managerial levels. Recommendations for future research are made.

Seasonal variation in food habits of the Italian hare in a south Apennine semi-natural landscape

The Italian hare is a species of hare endemic to central and southern Italy and to Sicily. It has been classified as a ‘vulnerable’ species by the International Union for Conservation of Nature (IUCN), as it is considered to have a high risk of extinction in the next decade. Despite its endangered status, little is known about its feeding habits. In the present study, the seasonal pattern of diet composition of a population of Italian hare occupying a semi-natural landscape was estimated by using the micro-histological technique of faecal analysis. The results showed that hares had a diversified diet, consuming plant parts from over 70 species. Like other Lepus sp. , the Italian hare consumed a large amount of herbaceous plants (e.g. Brachypodium sylvaticum, Trifolium pratense, Allium subhirsutum and Festuca arundinacea), although it complemented its diet seasonally with fruits of Prunus spinosa, Pyrus piraster and Malus sylvestris. Analysis of similarities (ANOSIM) evidenced significant differences among seasons, as a consequence of the seasonal occurrence of the various food items. Spring and autumn (R = 0.7482, P = 0.001), as well as spring and winter (R = 0.7398, P = 0.001), showed low diet similarities; these results were supported by similarity percentage analysis (SIMPER, average dissimilarity: > 71% between spring and autumn; > 69% between spring and winter) with taxa like P. spinosa, Cirsium strictus, T. pratense and Rosa canina making the greatest contributions to these differences. Higher similarities were instead found when comparing other seasons. This seasonal pattern of diet composition was clearly depicted in the graph from nonmetric multidimensional scaling (n-MDS) ordination. Our results highlight the importance of some plant taxa in the diet of the Italian hare and could be useful in managing reintroduction programs.
Aminoalkylated Merrifield Resins Reticulated by Tris-(2-chloroethyl) Phosphate for Cadmium, Copper, and Iron (II) Extraction

We aimed to synthesize novel substituted polymers bearing functional groups to chelate heavy metals during depollution applications. Three polyamine functionalized Merrifield resins were prepared via ethylenediamine (EDA), diethylenetriamine (DETA), and triethylenetetramine (TETA) modifications named, respectively, MR-EDA, MR-DETA, and MR-TETA. The aminoalkylated polymers were subsequently reticulated by tris-(2-chloroethyl) phosphate (TCEP) to obtain new polymeric resins called, respectively, MR-EDA-TCEP, MR-DETA-TCEP, and MR-TETA-TCEP. The obtained resins were characterized via attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), elemental analysis (EA), and thermogravimetric (TGA), thermodynamic (DTA), and differential thermogravimetric (DTG) analysis. The synthesized resins were then assayed to evaluate their efficiency to extract metallic ions such as Cd2
