Tämän strategian perustutkimukseen kuuluvan tutkimuksen tarkoituksena on selvittää liikesodan periaatteiden kuvautumista merisodan teoreetikon Sir Julian S. Corbettin kirjoituksissa. Tutkimuksen näkökulma on luonteeltaan teoreettinen ja perustuu Merivoimien tarpeeseen tutkia liikesodankäyntiä merisodassa. Tutkimuksen pääongelmana on: miten liikesodankäynnin periaatteet kuvautuvat J. S. Corbettin kirjoituksissa? Tutkimuksen alaongelmat ovat: mitä tarkoittaa liikesodankäynti? Mitkä ovat liikesodankäynnin keskeiset periaatteet ja teoriat? Mitkä ovat Corbettin merisodan teorian keskeisimmät opit? Mitä merisota on Corbettin mukaan? Tutkimuksen päälähteenä on Julian Corbettin merisodan teorian pääteos ”Some Principles of Maritime Strategy” vuodelta 1911. Liikesodan teorian päälähteenä on Robert Leonhardin teos ”The Art of Maneuver – Maneuver-Warfare Theory and AirLand Battle” vuodelta 1991. Tutkimusmenetelmänä on kuvaileva kvalitatiivinen tapaustutkimus. Tutkimuksessa kuvaillaan tutkimuskohteena olevan merisotateoreetikon, J. S. Corbettin merisodan teoriaa ja tarkastellaan sitä liikesodankäynnin teorian näkökulmasta. Liikesodankäynnin erottaa muista sodankäynnin muodoista sillä, miten liikesodassa määritetään voittoon tähtäävät keinot. Liikesodan teorian keskeisiin periaatteisiin kuuluvat vihollisen vahvuuksien välttäminen, vihollisen harhauttaminen, vihollisen haavoittuvuuksien tunnistaminen ja niitä vastaan hyökkääminen. Leonhard on jalostanut nämä edelleen kolmeksi toimintamalliksi: ennakoinniksi, dislokaatioksi sekä hajaannukseksi. Merisota on Corbettin mukaan taistelua meren ja meriyhteyksien hallinnasta. Laivaston tavoitteena tulee olla merenherruuden saavuttaminen. Saavuttamalla ja ylläpitämällä merenherruus kyetään toteuttamaan muut merivoimien tehtävät. Corbettia voidaan pitää yhteisoperaatio-ajattelun edelläkävijänä, sillä Corbettin mukaan sodassa operaatioihin tulee käyttää sekä maa- että merivoimia yhdessä. Corbett luokittelee merelliset operaatiot kolmeen kategoriaan: 1) merenherruuden varmistaminen, 2) merenherruuden kiistäminen, 3) merenherruuden hyödyntäminen. Tutkimuksen johtopäätöksenä havaittiin, että Sir Julian Stafford Corbettin kirjoituksissa esiintyvät näkemykset merisodasta ja merisodan teoriasta noudattavat pitkälti liikesodankäynnin periaatteita. Liikesodan perusperiaatteet vihollisen vahvuuksien välttämisestä, harhautukseen pyrkimisestä sekä vihollisen haavoittuvuuksien tunnistamisesta ja niitä vastaan hyökkäämisestä ovat voimakkaasti läsnä corbettiaanisessa merisodan teoriassa.

PURPOSE: To compare obstetric outcomes of induced preterm twin births (under 32 weeks gestation) with those spontaneously conceived. METHODS: Prospective study of twin pregnancies (25 induced and 157 spontaneously conceived) developed over a period of 16 years in a tertiary obstetric center. Demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were compared. RESULTS: The analysis of obstetrical complications concerning urinary or other infections, hypertensive disorders of pregnancy, gestational diabetes, fetal malformations, intrauterine fetal death, intrauterine growth restriction and intrauterine discordant growth reveal no significant statistical differences between the two groups. First trimester bleeding was higher in the induced group (24 versus 8.3%, p=0.029). The cesarean delivery rate was 52.2% in spontaneous gestations and 64% in induced gestations. Gestational age at delivery, birth weight, Apgar scores at first and fifth minutes, admissions to Neonatal Intensive Care Unit and puerperal complications show no statistically significant differences between the two groups. These results were independent of chorionicity and induction method. CONCLUSION: The mode of conception did not influence obstetric and neonatal outcomes. Although induced pregnancies have higher risk of first trimester bleeding, significant differences were not observed regarding other obstetric and puerperal complications and neonatal results.

Several papers document idiosyncratic volatility is time-varying and many attempts have been made to reveal whether idiosyncratic risk is priced. This research studies behavior of idiosyncratic volatility around information release dates and also its relation with return after public announcement. The results indicate that when a company discloses specific information to the market, firm’s specific volatility level shifts and short-horizon event-induced volatility vary significantly however, the category to which the announcement belongs is not important in magnitude of change. This event-induced volatility is not small in size and should not be downplayed in event studies. Moreover, this study shows stocks with higher contemporaneous realized idiosyncratic volatility earn lower return after public announcement consistent with “divergence of opinion hypothesis”. While no significant relation is found between EGARCH estimated idiosyncratic volatility and return and also between one-month lagged idiosyncratic volatility and return presumably due to significant jump around public announcement both may provide some signals regarding future idiosyncratic volatility through their correlations with contemporaneous realized idiosyncratic volatility. Finally, the study show that positive relation between return and idiosyncratic volatility based on under-diversification is inadequate to explain all different scenarios and this negative relation after public announcement may provide a useful trading rule.

ABSTRACTTo evaluate the effect of planting date and spatial pattern on common bean yield under weed-free and weed-infested conditions, an experiment was conducted in Kelachay, Northern Iran, in 2013. The experimental design was a randomized complete block in a factorial arrangement with three replicates. Factors were planting date (10 August and 20 August), spatial pattern (square and rectangular planting pattern, with a planting distance of 30 x 30 cm and 45 x 20 cm, respectively), and weed management regime (weed-free and weedy conditions, weeded and not weeded throughout the growing season, respectively). Results showed that the main effect of planting date was significant only for pod number per plant and seed number per pod. At the same time, pod number per plant, seed number per pod, pod length, and grain yield were influenced significantly by spatial pattern. Results of ANOVA have also indicated that all traits, except pod length, were influenced significantly by weed-management regimes. Moreover, effect of planting date and spatial pattern were nonsignificant for weed dry weight. Mean comparison has expressed a significant increment in seed yield for square planting arrangement (1,055 kg ha-1) over rectangular (971 kg ha-1). Weeding has also presented an overall 12% and 8% improvement in grain and pod yield over control (weedy check), respectively. Based on the results of this study, weed control, as well as square planting pattern, are recommended for obtaining the highest seed yield in common bean.

The chemical analysis of flesh and seed of date palm fruit (Kentichi) was evaluated. Carbohydrates were the predominant component in all studied date cultivars (~78.69-83.46 g/100g dry matter), followed by moisture content (~9.23-11.17%), along with moderate amount of fat (~0.56-7.10 g/100g dry matter), protein (~2.16-2.80 g/100g dry matter), and ash (~1.18-1.64 g/100 g dry matter). Some antioxidants (Ascorbic acid, total phenolic, total flavonoid, chlorophyll and carotenoids) were found in different values in both date fruit and seed. The physicochemical properties and antioxidant activity of both flesh and seed oil which was extracted using Hexane, Soxhlet and Modified Bligh - Dyer extraction methods were determined. The experimental results showed that temperature, different solvents and extraction time had significant effect on the yield of the date palm oil and physicochemical properties. Date Flesh oil showed an important free radical scavenging activity towards 1-1-diphenyl-2-picrylhydrazyl (DPPH) free radical.
