The role of IT in the logistics sector: the impact of DuPont model on the profitability of IT companies

Background: The information technology (IT) is presented in all levels of the supply chain, from the communication with suppliers, through the manufacture process and until the delivery to clients. Moreover, IT has a positive effect on the performance of the supply chain. In this context, it is important for the IT sector to register a positive evolution, in other words it is important that the IT companies to be profitable and to continue to exist on the market ensuring the provision of the necessary tools for the logistic sector. Therefore, the objective of this paper was to analyze the profitability of the IT companies and to identify which factors impact it. The importance of our study in the context of the logistic sector can be sustained by the fact that technology information constitutes a crucial strategic aspect for the logistics service providers and it is important to maintain a positive evolution of the IT sector. Methods: There was used a regression analysis which started from the factors of the DuPont model and afterwards supplemented by one factor identified based on the Stepwise method. Results: The results show that the profitability of the Romanian IT companies is influenced by the Net Profit Margin, the Asset Turnover, the Financial Leverage and the Sales Growth. Conclusions: More exactly, the profitability of these companies is impacted by the capacity to generate net income based on the sales performed (and indirectly by the management of the costs), the efficiency with which the assets are used in order to generate revenues, the financing source of the assets and by the growth of the sales volume. Our results may present importance for the financial management, investors and researches offering insights about the factors which should be observed in order to improve the profitability of an IT entity from Romania. The importance of this study for the logistics sector can be interpreted as following: knowing which is the evolution of the IT market from a country and which factors impact the profitability of it represents an asset from the point of view of the logistics aspects, as there can be provided insights in case that the continuity for the tools needed is uncertain. Future research direction may imply the analysis of the correlation between the evolution of the IT companies and the logistic sector. Considering the fact that, as far as we know, no similar study was performed at the level of the Romanian IT industry, the novelty and originality of the research is represented by the performance of the research at the level of this market.
Intersexual differences in age-specific parental effort in the house finch (Carpodacus mexicanus)

Although age-specific improvements in reproductive performance are common in iteroparous organisms, they are by no means universal. Reproductive tradeoffs are integral features of the life-histories of animal populations and may lead to complex breeding strategies among birds of different age. In particular, asymmetries in the costs and benefits of different components of reproduction for males and females may result in contrasting patterns of age-related parental investment between the sexes. We examined age-specific patterns of parental care in an eastern North American population of house finches (Carpodacus mexicanus) over a three-year period and found pronounced differences in the degree to which males and females provisioned young as they aged. Younger male house finches provided more care to offspring than did older males, yet in females it was the middle-aged mothers that provisioned young most often. This pattern of paternal care is inconsistent with conditionand experience-dependent investment, and instead may reflect male compensation for decreased maternal performance or an attempt by males to secure future breeding attempts with their mate. In contrast, the pattern of maternal provisioning mimics age-related trends in other female breeding efforts (e.g. clutch size, fledging success) for short-lived passerines, which may be governed by condition, experience, and the onset of senescence. These data emphasize the variability in parental tactics that characterizes birds of different sex and age, and the importance of considering the allocation of reproductive effort to competitions for mates, egg-production, and parental care in relation to age so that we may better understand the evolution of male and female breeding strategies in birds.
Pathotypes of cereal cyst nematodes, Heterodera spp., in Sweden.

Pathotype tests were carried out with a total of 97 populations of Heterodera avenae, the Gotland strain of H. avenae, H. hordecalis and H. bifenestra. The populations were grouped by their virulence on five barley differentials (resistance genes): Varde (Rha), Emir (Rha"E"), Ortolan (Rha1), KVL 191 (Rha2) and Morocco C.I. 3902 (Rha3). Ten reaction patterns could be distinguished. With the populations grouped according to morphological/taxonomic considerations, several groups could be further subdivided by reactions on additional differentials. Some of the tested populations did not reproduce on the oat differentials. None of the differentials showed complete resistance to all nematode populations. Virulence frequencies on Rha"E", Rha1, Rha2 and Rha3 were calculated for populations of Heterodera avenae and the Gotland strain. In spite of the complexity due to the occurrence of more than one species and the reactions of additional differentials there was considerable agreement with the results of earlier surveys. Pathotypes Ha11 and Ha 12 were dominant, followed by the main pathotypes G(West) and G(East) of the Gotland strain.
FACTORS HINDERING THE EFFECTIVE TEACHING OF INFORMATION AND COMMUNICATION TECHNOLOGY COURSES AS PERCEIVED BY OFFICE TECHNOLOGY AND MANAGEMENT TEACHERS

This study was undertaken to identify the factors hindering the effective teaching of ICT courses in Office Technology and Management programs. The need for this study arose because of the observed ineffective teaching of ICT courses in OTM which in turn defeats the aim of the curriculum which emphasized the practical teaching and learning of ICT courses. The study adopted the survey design. The population of the study was thirty-one lecturers/instructors in OTM departments in selected polytechnics in Niger State. The sample size was twenty-six and the sampling technique was the simple random sampling method. The instrument for data collection was a five-point rating scale questionnaire. The findings of the study revealed, among others, that instructors/lecturers in Office Technology and Management were professionally and academically qualified to teach ICT courses but lacked up-to-date re-training required to effectively deliver ICT courses to their students. It further revealed that there were insufficient number of ICT equipment, poor maintenance, incessant power failures, lack of multi-media teaching aids and use of inappropriate teaching methods. It was concluded that there were several factors hindering the effective teaching of ICT courses in OTM. It was recommended that the Government and Polytechnic administrators should adequately fund OTM departments in order to provide the much needed infrastructural and human capacity building required to effectively teach ICT courses in OTM departments.
Postemergence weed management in acetolactate synthase (ALS) resistant grain sorghum

Field experiments were conducted to evaluate the efficacy of nicosulfuron and nicosulfuron + rimsulfuron applied alone or in combination with various broadleaf herbicides in acetolactate synthase (ALS)-resistant grain sorghum. Herbicides were applied when weeds were 5 to 15 cm in height. Overall weed control was greater when nicosulfuron + rimsulfuron were applied with other herbicides than when it was applied alone. Results indicated that postemergence (POST) application of nicosulfuron and nicosulfuron + rimsulfuron is effective at controlling grasses including barnyardgrass, green foxtail, and giant foxtail. The research also showed that broadleaf weed control was more effective when nicosulfuron + rimsulfuron were applied with other broadleaf herbicides. A field study was conducted to evaluate the differential response of ALS-resistant grain sorghum to POST applications of nicosulfuron + rimsulfuron at three growth stages. Grain sorghum was treated with nicosulfuron + rimsulfuron at the 3to 5-leaf, 7to 9-leaf, or 11to 13leaf collar stage. Nicosulfuron + rimsulfuron injured grain sorghum when applied at the 3to 5leaf, and 7to 9-leaf collar stage, however, sorghum yields and plant height were only reduced for the 3to 5-leaf collar stage. Results indicated that nicosulfuron + rimsulfuron application at the 3to 5-leaf collar stage injured ALS-resistant grain sorghum, but application at 7to 9-leaf and 11to 13-leaf collar stages did not result in grain yield reduction. Greenhouse experiments were conducted to evaluate the efficacy, absorption, and translocation of nicosulfuron, rimsulfuron, and nicosulfuron + rimsulfuron. Barnyardgrass, green foxtail, longspine sandbur, and large crabgrass were treated at 5 to 10 cm in height. Barnyardgrass GR50 was the lowest and was the most susceptible to all herbicides whereas, large crabgrass had the highest GR50 for all herbicides and was the most tolerant. Barnyardgrass and large crabgrass were treated with 14C-nicosulfuron, 14C-rimsulfuron, or both and radioactivity was recovered at 7 DAT. Barnyardgrass absorption and translocation of nicosulfuron, rimsulfuron and nicosulfuron + rimsulfuron was higher than large crabgrass. Results may indicate that greater absorption and translocation of the herbicides may attribute to the differential response of the species to nicosulfuron, rimsulfuron, and nicosulfuron + rimsulfuron.

Detection of a Radio Bubble around the Ultraluminous X-Ray Source Holmberg IX X-1

We present C- and X-band radio observations of the famous utraluminous X-ray source (ULX) Holmberg IX X-1, previously discovered to be associated with an optical emission line nebula several hundred parsecs in extent. Our recent infrared study of the ULX suggested that a jet could be responsible for the infrared excess detected at the ULX position. The new radio observations, performed using the Karl G. Jansky Very Large Array (VLA) in B-configuration, reveal the presence of a radio counterpart to the nebula with a spectral slope of −0.56 similar to other ULXs. Importantly, we find no evidence for an unresolved radio source associated with the ULX itself, and we set an upper limit on any 5 GHz radio core emission of 6.6 μJy (4.1 × 1032 erg s−1). This is 20 times fainter than what we expect if the bubble is energized by a jet. If a jet exists its core component is unlikely to be responsible for the infrared excess unless it is variable. Strong winds which are expected in super-Eddington sources could also play an important role in inflating the radio bubble. We discuss possible interpretations of the radio/optical bubble and we prefer the jet+winds-blown bubble scenario similar to the microquasar SS 433.
Species of the genus Munidopsis Whiteaves, 1784 from the Indian and Pacific Oceans and reestablishment of the genus Galacantha A. Milne-Edwards, 1880 (Crustacea, Decapoda, Galatheidae)

Sixty-six species of the genus Munidopsis have been studied using specimens collected during numerous French expeditions carried out in the last decades in the deep-waters of the southwest Indian and southwest Pacific Oceans, between 140 and 4400 m. Twenty-five new species are described, and the diagnoses and illustrations of some relatively rare species (M. africana, M. debilis, M. lenzii, M. moresbyi, M. orcina, M. sinclairi, M. stylirostris and M. wardeni) are provided. The reestablishment of the genus Galacantha is proposed, including the descriptions/diagnoses and a key to all species. The genus contains nine species, including three new species (G. bellis, G. diomedeae, G. quiquei n. sp., G. rostrata, G. spinosa, G. subrostrata n. sp., G. subspinosa n. sp., G. trachynotus and G. valdiviae). The number of species collected by station is very small (usually one species), probably related to their low densities. However, in some samples, as many as five species have been found. The highest number of species have been observed in the Banda Sea (Indonesia) and Solomon Islands. The new records of some species greatly extend the previously known distribution range of the species.
Experimental and Numerical Study of The Crack Position and Depth Effects on Natural Frequencies of Turbine Blades.

Turbine blades are the most important and expensive part of turbines; the losses due to maintenance is very large so must be analyze the causes of failure that may occur due to manufacturing defects or vibrations resulting from operating and other service conditions. In this work will, focus on vibrationthat occurs due to operating conditions. The blade represents as a cantilever beam manufactured fromaluminum, a square crack have constant breadth 5 mm formed on the blade for positions from (5 to 30) cm to fixed end with different crack depths (2,4,6) mm.The experimental work results were computed by using impulse test, and numerical result gain using finite element method. Good agreement was found between the results.The results showed that the increasing in crack’s depth caused decreasing in the fundamental natural frequency of blade for all crack positions.
Conventional and organic cropping systems at Suitia V: Cereal diseases

The occurrence of diseases on barley and winter wheat was surveyed in a field experiment comparing four conventional and four organic cropping systems in 1982—88. On barley, foliar diseases were of minor importance regardless of the cropping system. On winter wheat, powdery mildew (Erysiphe graminis), yellow rust (Puccinia striiformis) and leaf blotch (Septoria nodorum) were more prevalent in conventional than in organic cropping systems. Root and foot rot diseases (Bipolaris sorokiniana, Fusarium spp. and Gaeumannomycesgraminis) were frequent on barley and winter wheat in each cropping system. B. sorokiniana infected stem bases and roots of barley more frequently in organic than in conventional cropping systems. During the first years of the study, a serious epidemic of G. graminis was recorded in certain organic cropping systems.

Organization of Knowledge and Taxation

This paper studies how income taxation interacts with the organization of knowledge and production, and ultimately the distribution of wages in the economy. A more progressive tax system reduces the time that managers allocate to work. This makes the organization of production less efficient and reduces wages at both tails of the distribution, which increases lower tail wage inequality and decreases upper tail wage inequality. The optimal tax system is significantly less progressive than the current one in the United States, because a less progressive tax system also generates a less unequal wage distribution.
Voluntary Disclosure with Uncertainty of Investors' Response: Evidence from M&A Conference Calls

We examine the voluntary disclosure theory’s prediction of heterogeneous stock market reaction to M&amp;A conference calls attributable to the uncertainty of investors’ response. Using a series of quantile regressions, we find that the incidence of conference calls is associated with both extremely negative and extremely positive M&amp;A announcement abnormal returns. We find that this heterogeneous stock market reaction occurs for both low and high levels of words/ forward-looking words. Furthermore, the heterogeneous stock market reaction is substantially weaker when M&amp;A conference calls are held after the firms observe the initial market reaction to the M&amp;A press release. These results are robust to a battery of robustness tests. Collectively, the findings support the uncertainty of investors’ response to voluntary disclosures that can be perceived by investors as very good or very bad news, as an important factor for examining the valuation implications of voluntary disclosures. <br>

Characterising the interaction between metastasis-associated protein S100A4 and non-muscle myosin IIA in vitro and in vivo

S100A4 is a member of the S100 family of proteins and increases the motility of many cell types. This is also thought to explain its association with the epithelialmesenchymal transition (EMT), a developmental program re-activated during tumourigenesis. Mechanistically, S100A4 interacts with a number of targets including Smad3 and liprin-β1; however, the best characterised is non-muscle myosin IIA (NMIIA) which regulates many aspects of the cytoskeleton. There is a large body of in vitro data indicating that S100A4 promotes the monomeric state of NMIIA; however, in vivo evidence for the interaction in cells is lacking. Accordingly, the first aim of this study was to determine if S100A4 interacts with, and promotes the monomeric state of NMIIA in A431 cells undergoing SIP1-induced EMT. Intriguingly, co-localisation analysis of S100A4 and NMIIA in A431-SIP1 cells using immunoelectron microscopy indicated that NMIIA is present in a folded, 10S state, and unfolded 6S state, and S100A4 interacts with both. This represents the first evidence of 10S and 6S states of NMIIA in non-muscle cells. In addition, FRAP analysis demonstrated that cells with attenuated expression of S100A4 turned over NMIIA with a slower rate, consistent with S100A4 promoting the monomeric state. The second part of the study explored the mechanism of the S100A4-NMMIA interaction. In vitro analysis of phosphomimetic S1916D and S1943D NMIIA showed no differences in binding affinity with S100A4 compared to WT NMIIA, contrary to the published literature. Based on the NMR structure of S100A4 and NMIIA, V77 and C81 were identified as key S100A4 residues that mediated the interaction with NMIIA. Mutation of these sites abolished the interaction with NMIIA, an effect reflected in null-phenotypes for both proteins when over-expressed in A431 cells compared to WT S100A4. In conclusion, this study suggests S100A4 is an important regulator of NMIIA dynamics in cells.
Relative Timing of Stiffening with Various Combinations of Nucleate and Enucleated Egg Fragments of Xenopus laevis

Previously, I found that in Xenopus eggs, the surface contraction wave (SCW) can arise at a point close to a male, a female or a zygote nucleus or a top portion of the egg (9). This finding suggested that all types of nucleus and cytoplasm of a Xenopus egg have the potential to determine the point of initiation of the SCW. Since stiffening is closely associated with the SCW, to determine the factors governing this phenomenon, I compared the times of egg stiffening of pairs of fragments containing different types of nuclei or cytoplasm. I found that the stiffening occurs earlier in fragments containing any type of nucleus than in those containing no nucleus, and earlier in fragments containing a male nucleus than in those containing a female nucleus. These results are consistent with the notion that either a nucleus or cytoplasm that induces the SCW earliest determines the point of initiation of the SCW close to itself. I also found that DNA replication is essential for the earlier occurrence of stiffening in a fragment containing a nucleus.
Resistencia bacteriana en cepas patógenas aisladas de mastitis en vacas lecheras de la V Región, Región Metropolitana y Xª Región, Chile* Bacterial resistance of mastitis pathogens isolated from dairy cows in the Vth Region, Metropolitan Region and Xth Region, Chile.

3Cooprinsem, Casilla 827, Osorno, Chile. SUMMARY Antimicrobial chemotherapy in human and veterinary medicine is one of the most important therapeutic tool against pathogenic agents causing infectious diseases; nevertheless, the development of multiple resistant strains during the last years has been reported. Some of the measures adopted to control this problem have been the veterinary prescription of antimicrobials for animal use, the permanent rotation of drugs, and the implementation of continuous monitoring programs for bacterial resistance. In the present paper the sensitivity of pathogenic bacteria isolated from dairy cows suffering mastitis in different regions of Chile against antimicrobials most frequently used in dairy herds is reported. The Plate Dilution Method and the Minimum Inhibitory Concentration (MIC) were used to evaluate the bacterial resistance of each isolated strain. A total of 449 bacterial strains were isolated from 963 aseptically collected milk samples in the 5th and Metropolitan Regions of Chile, E. coli being the most frequent mastitis pathogen recovered. In the 10th Region, however, S. aureus was the main pathogen among 1012 bacterial strains isolated from 2000 milk samples. S. aureus, Streptococcus spp and coagulase-negative Staphilococcus (CNS) were shown to be highly resistant to amoxicilin, ampicillin, penicillin, streptomycin and lincomicyn. Resistance to cloxacilin of S. aureus strains isolated in the 5th-Metropolitan and 10th Regions were 6.2% and 3.7% respectively. On the other hand, a high rate of sensitivity was observed in E. coli with resistance values below 25%. According to these results it is possible to conclude that the mastitis pathogens present in the geographical regions under study are resistant to more than one antimicrobial drug and, therefore, usage of these drugs under medical prescription and implementation of permanent monitoring programs for bacterial resistance are strongly recommended.
