Capacidade combinatória e parâmetros genéticos de genótipos de pinhão-manso quanto a caracteres morfoagronômicos

O objetivo deste trabalho foi determinar as capacidades geral e específica de combinação, os parâmetros genéticos e a correlação entre caracteres morfoagronômicos, em acessos de pinhão-manso (Jatropha curcas). Utilizou-se o delineamento experimental de blocos ao acaso, com três repetições. Foram avaliados os caracteres: PR, produção de sementes; AP, altura de planta; NRS, número de ramos secundários; NFF, número de flores femininas; DC, diâmetro de colo; P100, massa de 100 sementes; AR, altura de ramificação; e DCO, diâmetro de copa. A capacidade geral de combinação foi significativa para PR, NRS, DC, P100 e AR, enquanto a capacidade específica foi significativa apenas para NFF e NRS. As estimativas de herdabilidade foram superiores a 70%, em NRS, NFF, DC e AR. Observou-se correlações genotípicas positivas entre NRS e DC (0,942), NRS e AP (0,762), NRS e DCO (0,798), NRS e PR (0,759), DC e AP (0,738), DC e DCO (0,844), DC e PR (0,802), e DCO e PR (0,742); e negativas entre NRS e AR (-0,665), e DC e AR (-0,687). O NFF explicou mais de 50% da variação dos híbridos de pinhão-manso. A capacidade geral de combinação é preponderante na maioria das características avaliadas.

Feed intake and growth performance of goats supplemented with soy waste

The objective of this work was to evaluate the effects of supplemental feeding of soy waste on the feed intake and growth rate of goats. Twenty male crossbred (Boer x local) goats were assigned to two isonitrogenous diet groups: one of commercial pellet and the other of soy waste. The commercial pellet (1.0%) and soy waste (0.8%) were provided on the dry matter basis of body weight (BW) per day, to the respective group of each diet. The soy waste group had lower daily intakes of total dry matter (0.79 vs. 0.88 kg) and organic matter (665.71 vs. 790.44 g) than the group fed pellet; however, the differences on daily intakes for grass (0.62 vs. 0.64 kg), crude protein (96.81 vs. 96.83 g), and neutral detergent fibre (483.70 vs. 499.86 g) were not significant. No differences were observed between groups for BW gain. The feed conversion ratio and feed cost per kilogram of BW gain were lower for the group fed soy waste than for the one fed pellet. Goats fed supplemental soy waste have a lower total dry matter intake, feed conversion ratio, and feed cost per kilogram of body weight gain than those fed commercial pellets.

Suorituskyvyn johtamisen asiantuntijapalvelun tuotteistaminen

Aiempien tutkimusten mukaan suorituskyvyn mittauksella on selvä vaikutus henkilöstön työmotivaatioon ja toiminnan tehokkuuteen. Tämän vaikutuksen taustalla ovat tavoitteiden ymmärtäminen, viestinnän onnistuminen, vaikutusmahdollisuudet, palkitseminenja motivointi sekä koulutus ja työympäristö. Tutkimuksen tavoitteena on tutkia suorituskyvyn johtamisen asiantuntijapalvelun tuotteistamista. Tutkimuksessa perehdytään ensin asiantuntijapalvelun tuotteistamiseen kirjallisuuden perusteella,jonka jälkeen tätä teoriaa testataan käytännössä tuotteistamalla case-tapauksena oleva suorituskyvyn johtamisen asiantuntijapalvelu. Asiantuntijapalvelut ovat kaikkein abstrakteimpia palveluja, joten niiden tuotteistaminen on vaikeaa, mutta myös samalla erityisen tärkeää. Ne ovat monesti täysin asiakaskohtaisesti räätälöityjä, joka tekee muun muassa niiden hinnoittelusta ja myynnistä vaikeaa. Tuotteistamalla saadaan esimerkiksi asiantuntijapalveluiden tuottamisprosessit ja hinnat vakioitua, jolloin niiden kannattava myynti helpottuu. Tutkimuksen empiria-osassa tuotteistettiin case-tapaus ja tuotteistuksessa seurattiin erästä kirjallisuudessa esitettyä tuotteistusprosessimallia. Tutkimuksessa selvisi, että asiantuntijapalvelun tuotteistusprosessi sisältää useita eri vaiheita, joiden käsittelyyn on varattava aikaa. Lisäksi on tärkeää tutustua asiantuntijapalveluiden tuotteistamiseen jo ennen tuotteistamisen aloittamista. Suorituskyvyn johtamisen asiantuntijapalveluiden tuotteistamisessa voidaan hyvin käyttää yleisiä asiantuntijapalvelun tuotteistamisen teorioita. Tutkimuksesta saatuja tuloksia voidaan käyttää hyväksi suunniteltaessa ja valmisteltaessa asiantuntijapalvelun tuotteistamista ja tutkimus tarjoaa myös neuvoja tuotteistuksen toteutukseen.

Ore genesis of Pb-Zn deposits in the Nappe zone of Northern Tunisia: Constraints from Pb-S-C-O isotopic systems

The Jalta and Jebel Ghozlane ore deposits are located in the extreme North of Tunisia, within the Nappe zone. The mineralization of Jalta, hosted in Triassic dolostones and the overlying Mio-Pliocene conglomerates, consists of abundant galena, barite, and cerussite with accessory sphalerite, pyrite, and jordanite. At Jebel Ghozlane, large Pb-Zn concentrations occur in the Triassic dolostones and Eocene limestones. The mineral association consists of galena, sphalerite, barite, and celestite and their oxidation products (cerussite, smithsonite, and anglesite). Lead isotope ratios in galena from both districts are relatively homogeneous ((206)Pb/(204)Pb = 18.702-18.823, (207)Pb/(204)Pb = 15.665-15.677, (208)Pb/(204)Pb = 38.725-38.875). The delta(34)S values for sulfates from both areas (+12.2 to +16.2 parts per thousand at Jalta and + 14.3 to + 19.4 parts per thousand at Jebel Ghozlane) are compatible with a derivation of sulfur from marine sulfates, possibly sourced from the Triassic evaporites. The delta(34)S values of the sulfides have a range between -10 and +12.5 parts per thousand at Jalta, and between -9.1 and +22.1 parts per thousand at Jebel Ghozlane. The large range of values suggests reduction of the sulfate by bacterial and/or thermochemical reduction of sulfate to sulfur. The high delta(34)S values of sulfides require closed-system reduction processes. The isotopically light carbon in late calcites (-6.3 to -2.5 parts per thousand) and authigenic dolomite (-17.6 parts per thousand) suggests an organic source of at least some of the carbon in these samples, whereas the similarity of the delta(18)O values between calcite (+24.8 parts per thousand) and the authigenic dolomite (+24.7 parts per thousand) of Jalta and their respective host rocks reflects oxygen isotope buffering of the mineralizing fluids by the host rock carbonates. The secondary calcite isotope compositions of Jalta are compatible with a hydrothermal fluid circulation at approximately 100 to 200 degrees C, but temperatures as low as 50 degrees C may be indicated by the late calcite of Jebel Ghozlane (delta(18)O of +35.9 parts per thousand). Given the geological events related to the Alpine orogeny in the Nappe zone (nappe emplacement, bimodal volcanism, and reactivation of major faults, such as Ghardimaou-Cap Serrat) and the Neogene age of the host rocks in several localities, a Late-Miocene age is proposed for the Pb-Zn ore deposits considered in this study. Remobilization of deep-seated primary deposits in the Paleozoic sequence is the most probable source for metals in both localities considered in this study and probably in the Nappe zone as a whole.

Variabilidade genética entre acessos de Umbu-Cajazeira mediante análise de marcadores ISSR

A umbu-cajazeira (Spondias sp.) é uma frutífera nativa do Semiárido brasileiro, ainda em fase de domesticação, cujos frutos apresentam excelentes perspectivas de aproveitamento comercial. O objetivo deste trabalho foi caracterizar a variabilidade genética entre acessos de umbu-cajazeira pertencentes ao Banco Ativo de Germoplasma de Fruteiras Tropicais da Embrapa Mandioca e Fruticultura, por meio de marcadores moleculares ISSR (Inter Simple Sequence Repeat). Foram analisados 17 acessos de umbu-cajazeira, com 25 marcadores ISSR, os quais produziram um total de 249 bandas, sendo 201 bandas polimórficas e 48 monomórficas. As dissimilaridades genéticas entre os acessos variaram de 0,247 a 0,665, com base no coeficiente de Jaccard. O método UPGMA (Unweighted Pair-Group Method Average) agrupou os acessos em cinco grupos, sendo que 'Preciosa' e 'Suprema' foram os acessos mais similares. A maior dissimilaridade foi observada entre os acessos 'Esperança' e 'Pomar'. O alto grau de polimorfismo encontrado demonstrou a eficiência dos marcadores ISSR, indicando que estes podem ser utilizados com sucesso na caracterização molecular de germoplasma e em futuros trabalhos de melhoramento genético dessa frutífera. Existe considerável variabilidade genética entre os acessos de umbu-cajazeira presentes no BAG Fruteiras Tropicais, que pode ser explorada para a conservação e o melhoramento da espécie.

Identification-commitment inventory (ICI-Model): confirmatory factor analysis and construct validity

The aim of this study is to confirm the factorial structure of the Identification-Commitment Inventory (ICI) developed within the frame of the Human System Audit (HSA) (Quijano et al. in Revist Psicol Soc Apl 10(2):27-61, 2000; Pap Psicól Revist Col Of Psicó 29:92-106, 2008). Commitment and identification are understood by the HSA at an individual level as part of the quality of human processes and resources in an organization; and therefore as antecedents of important organizational outcomes, such as personnel turnover intentions, organizational citizenship behavior, etc. (Meyer et al. in J Org Behav 27:665-683, 2006). The theoretical integrative model which underlies ICI Quijano et al. (2000) was tested in a sample (N = 625) of workers in a Spanish public hospital. Confirmatory factor analysis through structural equation modeling was performed. Elliptical least square solution was chosen as estimator procedure on account of non-normal distribution of the variables. The results confirm the goodness of fit of an integrative model, which underlies the relation between Commitment and Identification, although each one is operatively different.

A thematic analysis of delusion with religious content in schizophrenia: open, closed, and mixed dynamics

The aim of the present study was to elicit how patients with delusions with religious contents conceptualized or experienced their spirituality and religiousness. Sixty-two patients with present or past religious delusions went through semistructured interviews, which were analyzed using the three coding steps described in the grounded theory. Three major themes were found in religious delusions: ''spiritual identity,'' ''meaning of illness,'' and ''spiritual figures.'' One higher-order concept was found: ''structure of beliefs.'' We identified dynamics that put these personal beliefs into a constant reconstruction through interaction with the world and others (i.e., open dynamics) and conversely structural dynamics that created a complete rupture with the surrounding world and others (i.e., closed structural dynamics); those dynamics may coexist. These analyses may help to identify psychological functions of delusions with religious content and, therefore, to better conceptualize interventions when dealing with it in psychotherapy.

The scope of Baker's law.

656 I. 657 II. 658 III. 660 IV. 661 V. 663 VI. 663 VII. 664 VIII. 664 665 References 665 SUMMARY: Baker's law refers to the tendency for species that establish on islands by long-distance dispersal to show an increased capacity for self-fertilization because of the advantage of self-compatibility when colonizing new habitat. Despite its intuitive appeal and broad empirical support, it has received substantial criticism over the years since it was proclaimed in the 1950s, not least because it seemed to be contradicted by the high frequency of dioecy on islands. Recent theoretical work has again questioned the generality and scope of Baker's law. Here, we attempt to discern where the idea is useful to apply and where it is not. We conclude that several of the perceived problems with Baker's law fall away when a narrower perspective is adopted on how it should be circumscribed. We emphasize that Baker's law should be read in terms of an enrichment of a capacity for uniparental reproduction in colonizing situations, rather than of high selfing rates. We suggest that Baker's law might be tested in four different contexts, which set the breadth of its scope: the colonization of oceanic islands, metapopulation dynamics with recurrent colonization, range expansions with recurrent colonization, and colonization through species invasions.

Capillarity and fibre types in locomotory muscles of wild yellow-legged gulls (Larus cachinnans)

This study analyzes the capillarity and fibre-type distribution of six locomotory muscles of gulls. The morphological basis and the oxygen supply characteristics of the skeletal muscle of a species with a marked pattern of gliding flight are established, thus contributing to a better understanding of the physiology of a kind of flight with low energetic requirements. The four wing muscles studied (scapulotriceps, pectoralis, scapulohumeralis, and extensor metacarpi) exhibited higher percentages of fast oxidative glycolytic fibres (>70%) and lower percentages of slow oxidative fibres (<16%) than the muscles involved in nonflight locomotion (gastrocnemius and iliotibialis). Capillary densities ranged from 816 to 1,233 capillaries mm(-2), having the highest value in the pectoralis. In this muscle, the fast oxidative glycolytic fibres had moderate staining for succinate dehydrogenase and relatively large fibre sizes, as deduced from the low fibre densities (589-665 fibres mm(-2)). All these findings are seen as an adaptive response for gliding, when the wing is held outstretched by isometric contractions. The leg muscles studied included a considerable population of slow oxidative fibres (>14% in many regions), which suggests that they are adapted to postural activities. Regional variations in the relative distributions of fibre types in muscle gastrocnemius may reflect different functional demands placed on this muscle during terrestrial and aquatic locomotion. The predominance of oxidative fibres and capillary densities under 1,000 capillaries mm(-2) in leg muscles is probably a consequence of an adaptation for slow swimming and maintenance of the posture on land rather than for other locomotory capabilities, such as endurance or sprint activities.

Prognostication of Mortality in Critically Ill Patients With Severe Infections.

BACKGROUND: The purpose of this study was to confirm the prognostic value of pancreatic stone protein (PSP) in patients with severe infections requiring ICU management and to develop and validate a model to enhance mortality prediction by combining severity scores with biomarkers. METHODS: We enrolled prospectively patients with severe sepsis or septic shock in mixed tertiary ICUs in Switzerland (derivation cohort) and Brazil (validation cohort). Severity scores (APACHE [Acute Physiology and Chronic Health Evaluation] II or Simplified Acute Physiology Score [SAPS] II) were combined with biomarkers obtained at the time of diagnosis of sepsis, including C-reactive-protein, procalcitonin (PCT), and PSP. Logistic regression models with the lowest prediction errors were selected to predict in-hospital mortality. RESULTS: Mortality rates of patients with septic shock enrolled in the derivation cohort (103 out of 158) and the validation cohort (53 out of 91) were 37% and 57%, respectively. APACHE II and PSP were significantly higher in dying patients. In the derivation cohort, the models combining either APACHE II, PCT, and PSP (area under the receiver operating characteristic curve [AUC], 0.721; 95% CI, 0.632-0.812) or SAPS II, PCT, and PSP (AUC, 0.710; 95% CI, 0.617-0.802) performed better than each individual biomarker (AUC PCT, 0.534; 95% CI, 0.433-0.636; AUC PSP, 0.665; 95% CI, 0.572-0.758) or severity score (AUC APACHE II, 0.638; 95% CI, 0.543-0.733; AUC SAPS II, 0.598; 95% CI, 0.499-0.698). These models were externally confirmed in the independent validation cohort. CONCLUSIONS: We confirmed the prognostic value of PSP in patients with severe sepsis and septic shock requiring ICU management. A model combining severity scores with PCT and PSP improves mortality prediction in these patients.

Final results of the SAKK 16/00 trial: a randomized phase III trial comparing neoadjuvant chemoradiation to chemotherapy alone in stage IIIA/N2 non-small cell lung cancer (NSCLC).

Aim: One standard option in the treatment of stage IIIA/N2 NSCLC is neoadjuvant chemotherapy followed by surgery. We investigated in a randomized trial whether the addition of neoadjuvant radiotherapy would improve the outcome. Here we present the final results of this study. Methods: Patients (pts.) with pathologically proven, resectable stage IIIA/N2 NSCLC, performance status 0-1, and adequate organ function were randomized 1:1 to chemoradiation (CRT) with 3 cycles of neoadjuvant chemotherapy (cisplatin 100 mg/m2 and docetaxel 85 mg/m2 d1, q3weeks) followed by accelerated concomitant boost radiotherapy (RT) with 44 Gy in 22 fractions in 3 weeks, or neoadjuvant chemotherapy alone (CT), with subsequent surgery for all pts. The primary endpoint was event-free survival (EFS). Results: 232 pts. were randomized in 23 centers, the median follow-up was 53 months. Two thirds were men, median age was 60 years (range 37-76). Histology was squamous cell in 33%, adenocarcinoma in 43%. Response rate to CRT was 61% vs. 44% with CT. 85% of all pts. underwent surgery, 30-day postoperative mortality was 1%. The rate of complete resection was 91% (CRT) vs. 81% (CT) and the pathological complete remission (pCR) rate was 16% vs. 12%. The median EFS was 13.1 months (95% CI 9.9 - 23.5) for the CRT group vs. 11.8 months (95% CI 8.4 - 15.2) in the CT arm (p 0.665). The median overall survival (OS) with CRT was 37.1 months (95% CI 22.6 -50), with CT 26.1 months ( 95% CI 26.1 - 52.1, p 0.938). The local failure rate was 23% in both arms. In the CT arm 12 pts. were given postoperative radiotherapy (PORT) for R1 resection, 6 pts. received PORT in violation of the protocol. Pts. with a pCR, mediastinal downstaging to ypN0/1 and complete resection had a better outcome. Toxicity of chemotherapy was substantial, especially febrile neutropenia was common, whereas RT was well tolerated. Conclusions: This is the first completed phase III trial to evaluate the role of induction chemoradiotherapy and surgery, in comparison to neoadjuvant CT alone followed by surgery. RT was active, it increased response, complete resection and pCR rates. However, this failed to translate into an improvement of local control, EFS or OS. Notably, surgery after induction treatment was safe, including pneumonectomy. The overall survival rates of our neoadjuvant regimen are very encouraging, especially for a multicenter setting.
