Partner Type Diversity in Alliance Portfolios: Multiple Dimensions, Boundary Conditions and Firm Innovation Performance

Our research extends the current knowledge based view on the configuration of alliance portfolios and their deployment in different external knowledge environments. We study these alliance portfolios in a longitudinal sample (1996–2010) for over three thousand firms that operate in a large number of industries in the Netherlands. Our findings indicate that partner type variety and partner type relevance, as different dimensions of partner diversity in alliance portfolios, both have an inverted U‐shaped association with firm innovation performance. However, alliance portfolios characterized by both high partner type variety and high relevance cause inferior innovation performance. Different external knowledge environments, characterized by different levels of industry modularity and scope of knowledge distribution, moderate the inverted U‐shaped associations of partner type variety and relevance in alliance portfolios with firm innovation performance in opposing directions. While for partner type variety, a high level is found to be optimal in environments with greater modularity or broader scope of knowledge distribution, for partner type relevance it turns out that a low level is optimal under more modular industry conditions.
Effect of Some Trace Elements on Growth , Yield and Chemical Constituents of Trachyspermum ammi L ( AJOWAN ) Plants under Sinai Conditions

spraying of iron, zinc and manganese as each alone at 50 or 100 ppm or in triple combination of them at 50 ppm for each on plant grown under sandy soil conditions resulted in significant enhancement of the vegetative characters of Trachyspermum ammi L. in addition to essential oil percentage, essential oil yield/plant, oil components ,NPK, Fe, Zn, Mn and total carbohydrate content in the herb. The triple combination of them surpassed the solo application of each. The major oil component was thymol giving 55.51% with the triple combination. Ñ-cymene came in the second order of thymol giving 31.42% and ã-terpinene in the third order by 20.66% and followed by á-pinene in the 2.62% for the same treatment.
Oxygen dynamics and porewater transport in sediments inhabited by the invasive polychaete Marenzelleria viridis.

The polychaete Marenzelleria viridis is an invasive species and often replaces the native Nereis diversicolor. This shift leads to more reduced conditions and changes in the biogeo- chemical function of the sediments. By combining imaging techniques for O2 (planar optodes) and irrigation patterns (rhodamine WT and brilliant blue), we investigated the relationship between irrigation and O2 dynamics in burrows of M. viridis. The investigated animals shifted between 2 modes of ventilation: ciliary pumping for 77% of the time and muscular pumping for 23% of the time. On average, muscular pumping was induced every 0.4 h. During ciliary pumping, oxic water was pumped into blind-ended burrows and into the surrounding sediment, inducing an upward porewater transport of O2-depleted water. This pattern was reversed during muscular pumping. The 2 pumping modes induced oscillating O2 penetration along the burrow wall and along the primary sediment-water interface. The average net downward irrigation rate, including both pumping modes, amounted to 11.1 × 10 �3 ± 2.4 × 10 �3 ml min �1 . The estimated average oxic sediment volume was 2.1 ± 0.5 cm 3 per burrow, and the burrow-specific O2 consumption was 45.6 ± 18.1 nmol min �1 . M. viridis burrows and the ambient sediment are relatively O2 depleted, with intensified rates of O2 consumption, compared to similar-sized native N. diversicolor. The complex O2 dynamics induced a unique microenvironment that must favor meiofauna and micro- bial communities that are tolerant to oxic-anoxic oscillations or that have the ability to migrate along with the pulsing oxic-anoxic interface.
Design and Tests of a New Rest Gas Ionization Profile Monitor Installed in the SPS as a Prototype for the LHC

Based on the encouraging results obtained with a Rest Gas Ionization Profile Monitor of a first generation, a new monitor was designed and then installed in the SPS at the beginning of 2002. Its design fulfills all the requirements for a future installation in the LHC where four such monitors are foreseen. After the initial tests performed during the run of 2002, a few upgrading steps appeared necessary mainly in order to cope with the nominal LHC beam characteristics. They were implemented during the subsequent winter stop and the operation of the monitor was resumed in 2003 under various conditions of beam, ranging from an LHC pilot bunch up to beams having nominal distributions in bunch number, intensity and energy in the SPS for injection into the LHC. After a description of the monitor design, the measurements performed with the instrument during these last two years are discussed with the difficulties encountered and the corresponding implemented cures. Data acquired in 2003 on the whole spectrum of LHC beam characteristics are presented and the modifications made to prepare the 2004 campaign with a view to still improve the performance are also discussed.
Food Extrusion Technology: Initiatives to Address Food and Nutrition Insecurity in South Africa

The use of extrusion can be regarded as beneficial due to its short production time and wide variety of foods produced by this method. South Africa as a developing country has been involved in food extrusion since the 1980â€™s and this technology is gaining momentum in academic research areas. A number of research efforts related to extrusion in South Africa have shown the consumption of extruded dry beans can reduce plasminogen activator inhibitor levels in hyperlipidaemic men; the production of sorghum-cowpea extruded instant porridge resulted in a nutritional acceptable product and can be used to supplement the diet of young children to assist with protein deficiencies. Furthermore, research has proven extruder parameters play a role in the outcome of the product and can influence product properties. Based on these research initiatives, Vaal University of Technology/Centre of Sustainable Livelihoods (VUT/CSL) has acquired an Extrusion Pilot Plant to implement interdisciplinary research of nutrition and engineering science. The research will look at process optimisation studies to obtain maximum product output and evaluating nutritional compositions of the products under various conditions. It is hoped the future research efforts at VUT/CSL will address food and nutrition insecurity and showcase the pilot plant as a testing facility and potential advancement to commercialisation.
Culture of human cryopreserved ovarian tissue: effect of activin A and GDF9

Cryopreservation of ovarian tissue is one approach to preserve fertility of young women who are at risk of premature ovarian failure, due principally to a gonadotoxic treatment. The cryopreserved ovarian tissue has essentially immature oocytes, which need to be maturating for ulterior fertilization. Oocyte maturation can be achieved by transplantation or by maturation in vitro, which was the subject of this work. The present work was developed to evaluate the morphology and evolution of follicles using three markers of cellular quality [two apoptotic markers (p53 and Bcl2) and one proliferating marker (Ki67)] during 14 days of culture for three different culture media, without matrix support. For this comparative study we used a serum free medium (control group) to which we added two proteins from the Transforming Growth Factors superfamily Activin A and GDF-9. A diminution of the follicular population was observed throughout the culture and for all the culture media. However, the higher proportion of degenerating follicles (increasing with the time of culture) were observed at the Activin A group (A) and GDF-9 group (G) representing the lower proportion. For the three culture media only three type of follicles were seen (primordial, early primary and primary). All GCs in the three culture media were negative for Bcl2 immunostaining. Positive marking were observed for the apoptotic marker (p53) and for the proliferating marker (Ki67) in all culture. This study indicate a better survival in the group cultured with GDF-9, a higher number of follicles and cells of the granulosa in the first 10 days of culture
Folding and inversion tectonics in the Anti‐Atlas of Morocco

The late Variscan Anti‐Atlas of Morocco shows some conspicuous deviations from the standard anatomy of foreland fold‐and‐thrust belts. Large basement inliers crop out at a very short distance of less than 50 km behind the southeastern front of the fold belt, reminiscent of Windriver‐style basement uplifts. In contrast to the Rocky Mountain foreland, however, the Anti‐Atlas basement uplifts punctuate tightly folded Paleozoic cover series similar in tectonic style to the Appalachian Valley and Ridge province. Cover shortening is exclusively accommodated by buckle folding, and the Anti‐Atlas fold belt lacks any evidence for duplexing or thrust faults other than the occasional steep reverse fault found near basement inliers. Basement domes have classically been considered as the result of vertical tectonics in a horst and graben fashion, or, alternatively, as large “plis de fond” [ Argand, 1924 ], basement folds. Unfolding of a large portion of an Ordovician quartzite marker bed reveals a minimum shortening of 17% (30 km). Balancing this section at the crustal scale indicates a lower crustal detachment level at 18 to 25 km depth. Basement shortening is inferred to be accommodated through massive inversion of former extensional faults, inherited from a Late Proterozoic‐Lower Cambrian rifting phase.
An Examination of Anime Fan Stereotypes

We tested the veracity of existing stereotypes about anime fans. Self-identified anime fans, both convention-going and online, completed a survey which assessed demographic variables and measures of stereotype-consistent behaviors, attitudes, and physical appearance. Furry fans, fantasy sport fans, and a sample of undergraduate college students served as comparison groups. Of the 24 stereotypes tested in the present study, only nine showed evidence of being consistent with anime fans’ self-descriptions. These results reveal a significant discrepancy between non-fan perceptions of anime fans and the actual beliefs and behaviors of anime fans.
Oscillatory flow in a tube with time-dependent wall deformation and its application to Myocardial Bridges

In this paper we numerically investigate a one-dimensional model of blood flow in the human coronary arteries. The nonlinear hyperbolic system is expressed in terms of the cross-sectional area, flow velocity and pressure (A, u, p). The more widely studied linearised system is also discussed where conservation of static pressure, instead of total pressure, is enforced. The method of outgoing characteristics is used to satisfy the interface conditions, while a three-element windkessel model is adopted as outflow condition at the terminals of the network. Inside the segmental domain the leap-frog method is used for numerical integration. Within the context of this model we pay particular attention to the case when abrupt or smooth, space and time dependent variation of cross-sectional area of an artery is caused by externally prescribed motion of the vessel walls (e.g. myocardial bridge, flow watch). The derivation of the model and the numerical implementation are detailed. They are applied to model numerical experiments of the arterial system. Additionally to a system studied in [10, 15, 22, 28] the coronary arteries are parameterised. The main features of the flow through myocardial bridges are discussed.
NEW FOSSIL WOODS FROM THE PALEOGENE OF DOUPOVSKÉ HORY AND ČESKÉ STŘEDOHOŘÍ MTS . ( BOHEMIAN MASSIF , CZECH REPUBLIC )

New fossil woods are described from the Paleogene volcanoclastic sediments of Doupovské hory (localities Vrbice and Nechranice) and České středohoří Mts. (localities Bečov and Divoká rokle). Three types of conifer woods were identified (two stem woods and one root wood of Cupressaceae s.l.) and six types of angiosperm woods (families Lauraceae, Betulaceae, Ulmaceae, Malvaceae, Sapotaceae and one problematic sample). Two fossil conifer species encompassing the three conifer wood types (stem of Glyptostroboxylon rudolphii and stem and root of Taxodioxylon gypsaceum) were already known from the Tertiary of northwestern Bohemia. Five angiosperm species (Cinnamomoxylon seemannianum, Alnus tschemrylica, Ulmoxylon cf. kersonianum, Grewioxylon ortenburgense, Manilkaroxylon sp.) are documented for the first time in the studied area by our material; the sixth type of angiosperm wood we labelled only as “Xylotype Nechranice 1”, since its poor preservation made precise identification impossible. ■ fossil conifer wood, fossil angiosperm wood, systematic palaeobotany, volcanoclastic sediments, Doupovské hory Mts. , České středohoří Mts. , Oligocene, Czech Republic Received November 30, 2015 Issued December, 2015 AC TA MUSEI NATIONALIS PRAGAE Series B – Historia Naturalis • vol. 71 • 2015 • no. 3–4 • pp. 377–398 DOI 10.14446/AMNP.2015. 377 SBORNÍK NÁRODNÍHO MUZEA V PRAZE Řada B – Přírodní vědy • sv. 71 • 2015 • čís. 3–4 • s. 377–398
Effect of Steaming and Boiling on the Antioxidant Properties and Biogenic Amines Content in Green Bean (Phaseolus vulgaris) Varieties of Different Colours

Effects of boiling and steaming cooking methods were studied on total polyphenols, antioxidant capacity, and biogenic amines of three green bean varieties, purple, yellow, and green. The vegetables gave good values both for antioxidant capacity and for phenolics content, with the purple variety being the richest in healthful components. Both the heat treatments affected the antioxidant properties of these vegetables, with boiling that reduced the initial antioxidant capacity till 30% in the yellow variety, having the same trend for total polyphenols, with the major decrement of 43% in the green variety. On the contrary, biogenic amines significantly increased only after boiling in green and yellow variety, while purple variety did not show any changes in biogenic amines after cooking. The steaming method showed being better cooking approach in order to preserve the antioxidant properties of green beans varieties and to maintain the biogenic amines content at the lowest level.
Differences in Gene Expression Profiles between Human Breast Tissue and Peripheral Blood Samples for Breast Cancer Detection

The purpose of this study is to check the similarities of differential gene expression of 11 genes in breast cancer tissue and blood samples from the same individual for early detection of breast cancer. We had investigated differential gene expression by qRT-PCR in 20 breast cancer patients’ tumoral tissues and corresponding blood sample. In our analysis BRCA2, HER-2, ER, PR, MET and BRAF mRNA levels were significantly over expressed in tumoral tissues. ER and PR mRNA levels were not detected in any of the peripheral blood samples, whereas KRAS and PTEN mRNA levels were not detected in any of the tumoral tissues. HER-2 (45%), EGFR (40%) and PI3KCA (30%). KRAS and PTEN mRNA levels were significantly over expressed in peripheral blood. In the correlation analysis expression of most of the genes were significantly altered in grade II and III in the tissues, where as in premenopausal women mRNA expression was significantly high in Grade II and III and ER/PR negative tumors. Our results suggests that BRCA2, ER, PR, PI3KCA, MET and BRAF differential gene expression at mRNA levels showed no diagnostic value as a marker of circulating tumour cells in breast cancer. qRT-PCR may be suitable alternative method for the determination of HER-2, EGFR, PI3KCA KRAS and PTEN mRNA status in the blood of breast cancer patients. Premenopausal women with high grade (Grade II and III) and ER/PR negative cases may be associated with proliferation/metastasis, high recurrence rate, and poor prognosis.
Reanalysis of Vernalization Data of Wheat and Carrot

Abstract Vernalization is an important determinant of the growth, development, and yield of biennial and perennial crops. Accurate simulation of its response to temperature is thus an important component of successful crop systems modelling. Vernalization has a low optimum temperature compared to other temperature responses of plants, and thus may be difficult to treat using expressions that are appropriate for other plant processes. This paper examines the application of a simple equation that has been used for other processes. It reads as v=V max ( T max - T T max - T opt ) ( T T opt ) T opt T max - T opt , where v is the daily rate of vernalization progress at temperature T, T opt and T max are the optimum and maximum temperatures for vernalization, respectively, and V max is the maximum daily rate of vernalization (the inverse of the minimum number of days required to complete vernalization), which occurs at T opt . The model was applied to published vernalization data for wheat and carrot. The fits to data were good (adjusted R 2 for wheat of 0.94, for carrot 0.98), with estimated T opt and T max being 5.7±0.5 and 21.3±1.4 °C, respectively, for wheat ‘Norin 27’ and 6.6±0.2 and 14.1±0.3 °C for carrot ‘ Chantenay Red Cored’. The estimated parameters, in particular the high T max for wheat, were close to those reported using different analytical approaches. It was suggested that the function would be useful for summarizing vernalization data, and that its use would avoid the abrupt changes that are inevitable when different linear relationships are used for part of the overall response. It was also suggested the high T max should be taken into account when interpreting data obtained with wheat grown under warm conditions.
Exports and Capacity Constraints: Evidence for Several Euro Area Countries

We argue that, under certain conditions, firms consider exports as a substitute for domestic demand. Our econometric model for six euro area countries suggests domestic demand and capacity constraints as additional variables for export equations. We apply the exponential and logistic variant of a smooth transition regression model and find that domestic demand developments are relevant for short-run export dynamics particularly during more extreme stages of the business cycle. A substitutive relationship between domestic and foreign sales can most clearly be found for Spain, Portugal and Italy, providing evidence of the importance of sunk costs and hysteresis in international trade.
Financial frictions, informality and income inequality

We studied the effects of changes in banking spreads on distributions of income, wealth and consumption as well as the welfare of the economy. This analysis was based on a model of heterogeneous agents with incomplete markets and occupational choice, in which the informality of firms and workers is a relevant transmission channel. The main finding is that reductions in spreads for firms increase the proportion of entrepreneurs and formal workers in the economy, thereby decreasing the size of the informal sector. The effects on inequality, however, are ambiguous and depend on wage dynamics and government transfers. Reductions in spreads for individuals lead to a reduction in inequality indicators at the expense of consumption and aggregate welfare. By calibrating the model to Brazil for the 2003-2012 period, it is possible to find results in line with the recent drop in informality and the wage gap between formal and informal workers
The Contribution of Artisanal Fisheries towards Livelihoods and Food Security among Communities of Chanyanya Fishing Camp in Kafue District of Lusaka Province

A study was conducted to assess the contribution of artisanal fisheries towards livelihoods and food security among communities of Chanyanya fishing camp in Kafue district. With the help of members of staff from the Department of Fisheries, fifty households were randomly selected and administered with semistructured questionnaires and personal interviews. The data was analysed using statistical package for social sciences (SPSS), while graphs and charts were done in Microsoft Excel. Results have shown that an artisanal fishery has immensely contributed towards improved livelihoods of many households in Chanyanya. It has provided employment, income and food security, both to the local people and the nation at large. The study revealed that, 94% of them derived their livelihood from fishing, which provided them with the much needed income and employment. Other fishers, over the years developed fishing skills such as net mending, fish processing and boat making. The money realised from fishing was used to build houses, buy fishing equipment and household needs, and pay for their children’s school fees and health care, which thus contributed to their improved livelihood and food security. The study further revealed that all the fishers ate and shared some of the fish they caught amongst their kinsmen. In the same vein, fish was the most abundant, cheap and readily available source of protein amongst the consumers. It can therefore, be concluded that artisanal fisheries, contributes significantly towards livelihoods and food security among communities of Chanyanya fishing camp.
Sex Hormones and Gender Role Relate to Gray Matter Volumes in Sexually Dimorphic Brain Areas

The present study investigates the relationship of circulating sex hormone levels and gender role to gray matter volumes in sexually dimorphic brain areas and explores, whether these relationships are modulated by biological sex (as assigned at birth based on sexual anatomy) or oral contraceptive (OC) use. It was hypothesized that testosterone and masculinity relate positively to gray matter volumes in areas that are typically larger in men, like the hippocampus or cerebellum, while estradiol/progesterone and femininity relate positively to gray matter volumes in the frontal cortex. To that end, high resolution structural MRI scans, sex hormone levels and gender role self-assessments were obtained in a large sample 89 men, 89 naturally cycling (NC) women, and 60 OC users. Men showed larger regional gray matter volumes than women in the cerebellum and bilateral clusters spanning the putamen and parts of the hippocampi/parahippocampi and fusiform gyri. In accordance with our hypotheses, a significant positive association of testosterone to hippocampal volumes was observed in women irrespective of OC use. Participant’s self-reported femininity was significantly positively associated with gray matter volumes in the left middle frontal gyrus (MFG) in men. In addition several differences between OC-users and NC women were identified.
Utilization of the red mangrove prop root habitat by fishes in south Florida

The inherent difficulty of sampling the red mangrove prop root habitat has impeded our understanding of the utilization of this habitat by fishes. A block net and rotenone method was developed and used to sample 2 sites in each of 4 regions in Everglades National Park, Florida (USA). At each site a 3 mm mesh net was used to enclose 3 sides of a mangrove stand while an onshore berm formed the fourth side. Samples collected from the mangrove prop root environment were compared with samples collected using a 2-boat otter trawl in the immediately (8 to 10 m) adjacent, fringing seagrass habitat. The density and biomass of fish collected by the 2 gear were greater in the prop root habitat than in the adjacent fringing seagrass areas. There also were consistent differences in species composition between the 2 hab~tat types across all 4 geographic regions. Analysis of the stomach contents of gray snapper Lutjanus griseus suggested that smaller snapper tend to feed in the prop root habitat while larger snapper may forage out into adjacent areas to feed. The red mangrove prop root habitat is utilized by a wide variety of fish, and greater attention should be given to evaluating its contribution to fish production in south Florida and elsewhere.
