Organizational Climate and Turnover Intentions moderated by Leadership Style
Authors: Rabia Kanwal
Published: April 2024

There have been broad explorations of organizational climate, turnover intentions, and leadership styles in significant organizational contexts, but these have been mainly conducted in European countries or developed countries. Despite the well-off and rising literature on the subject, there needs to be more discernment of how leadership style affects organizational climate and turnover intentions in underdeveloped countries. Against this scenario, this study demonstrates the relationship of organizational climate with turnover intentions and the moderating role of transformational leadership style. Besides, the study tested the influence of transformational leadership style on organizational climate and turnover intentions. The study is conducted on faculty members of Southern Punjab University. Three hundred fifty questionnaires were distributed among faculty members, and the return questionnaire rate was 94%. The present study used a quantitative research design. The data was collected through a structured questionnaire and used a simple random sampling technique. For the said purpose, correlation and regression analysis are used to conclude.
Moreover, a significance test (t-test and ANOVA) was used to check the impact of demographics on independent and dependent variables. AMOS graphics and SPSS are used as analysis tools. The regression showed a significant relationship between the dependent variable (turnover intentions) and the independent variable (organizational climate). Still, transformational leadership does not mediate the relationship between organizational climate and turnover intentions. Chronchbach alpha value shows the reliability of data, and it shows the data that is used in this research is reliable; the significance value of the F-test shows the validity of the model, and in this research, the significant matter is .017, which indicates that the model is valid.

Published: April 2024

Background: Numbers of migrant workers have been increasing in Thailand, 69% of low skilled migrant workers are from Myanmar. Migrant workers are at highest risk of work-related injury and illness as compared to immigrants. There is limited study focusing on the magnitude of health seeking behavior and its associated factors among Myanmar migrant workers in Thailand.
Objectives: To determine the proportion of the health seeking behavior and its associated factors among Myanmar migrant workers.
Methods: This was an analytical cross-sectional study using quantitative data   where 423 Myanmar migrant workers were included and the study was carried out in the Khon Kaen province, Thailand. Community people working in a fishing net factory and a construction site were selected by simple random sampling method.  Data collection was done via face-to-face interviews. Multiple logistic regression was used for data analysis. The association was described with Adjusted Odds Ratio (AOR) and its 95% Confidence Interval (95% CI) at the statistically significant level of p value < 0.05.
Results: A total of 423 participants aged between 18 and 56 years (mean: 30.89 ± 7.95 years) and 61.7% currently married were enrolled in this study. Three-fourths (76.36%) of participants had income of more than 10,000 baths per month. Around 87% respondents were healthy. Overall, 46.81% of participants had appropriate health seeking behavior. Factors significantly associated with appropriate health seeking behavior were fishing net factory workers (AOR:1.80, 95% CI: 1.03-3.13), ability to speak Thai (AOR: 2.58, 95% CI: 1.52-4.39), non-drinkers (AOR: 1.60, 95% CI: 1.01-2.53), unhealthy workers (AOR:2.30, 95% CI: 1.21-4.39), injured (AOR: 3.33, 95% CI: 1.67-6.61) and having chronic diseases (AOR: 2.92,95% CI: 1.55-5.52).
Conclusion: The proportion of appropriate health seeking behavior of Myanmar migrant workers was unsatisfactory.  Occupation, ability to speak Thai, nondrinker, unhealthy, injury and chronic diseases were statistically significantly associated with appropriate health seeking behavior. Language translators should be assigned in the health centres to solve the barrier of health seeking behaviour of Myanmar migrant workers.

Published: April 2024

Background: The worldwide health scenario is undergoing a shift from infectious diseases to non-communicable ones, and diabetes is now the seventh major contributor to global mortality. Depression, anticipated to be the second-highest contributor to Disability Adjusted Life Years by 2020, presents a notable public health challenge. The probability of experiencing depression is elevated two to three times in individuals with diabetes, particularly those diagnosed with Type 2 diabetes.
Objectives: To assess the prevalence of depression and associated factors in Type 2 diabetic patients in Tribhuvan University Teaching Hospital.
Methods: An analytical cross-sectional study was conducted among 151 Type 2 diabetic patients visiting Tribhuvan University Teaching Hospital, Nepal. Patients were selected by systematic random sampling at an interval of every third diabetic patient attending the Out-Patient Department. Depression was assessed using the Beck Depression Inventory. Data was analyzed using STATA-14 where logistic regression was performed to ascertain associations (P value <0.05) of sociodemographic, behavioral and clinical characteristics with depression.                       
Results: The prevalence of depression among Type 2 diabetic patients was 28.5%. Among them, 15.2% had mild depression, 11.9% had moderate depression and 1.4% had severe depression. The odds of having depression was 1.24 times higher with 1 unit increase in HbA1C level (AOR=1.24, 95%CI:1.09-1.42, P-value=0.001), 4.62 times higher in patients having retinopathy as comorbidity (AOR=4.62, 95%CI:1.63-13.11, P-value=0.04) and 6.36 times higher in patients taking insulin for treatment (AOR=6.36, 95%CI:1.79-22.53, P-value=0.004) after adjusting for age, sex, occupation, marital status, ethnicity income and education.
Conclusion:  The study revealed that more than a quarter of Type 2 diabetic patients in this sample experienced depression. Factors such as HbA1C, treatment by insulin and retinopathy as comorbidity were identified as significant contributors. These findings highlight the emerging problem of depression among diabetic patients, emphasizing the need for integrated mental health services in diabetes care.

Authors: Acharya Yunika , Regmi Urja , Paudel Pratiksha
Published: April 2024

Background: The prevalence of mental illness among adolescents is a growing concern, with projections indicating that one in five adolescents experience a mental illness annually. Persistent negative beliefs and stigma surrounding mental illness often lead to discrimination, creating barriers that hinder individuals from seeking the help they need. Additionally, the neglect of mental health issues, especially in developing countries like Nepal, is influenced by deep-seated social and cultural factors that are not widely acknowledged.
Objectives: To assess the association of belief towards mental illness and help seeking behaviour among undergraduate students of Lalitpur district, Nepal.
Methods: An analytical cross-sectional study was conducted among 400 undergraduate students of management faculty in Lalitpur district. Belief towards Mental Illness scale was used to assess belief and self-reported questionnaire was used for assessing help seeking behaviour. Univariate and multivariable logistic regression analyses were performed to assess the association between beliefs and help seeking behaviour adjusting for the confounders.
Results: More than half of the respondents had negative belief towards mental illness. Seventy-nine percent of the respondents had previously sought help while experiencing any kind of mental illness. The odds of not seeking help is higher by 1.71 times among those who had negative belief towards mental illness compared to those who had positive belief (95% CI 1.03,2.8) adjusting for the confounders.
Conclusion: Those students who had negative belief were less likely to seek help. This highlights the urgent need to address these negative beliefs through targeted interventions, aiming to alleviate such perceptions and foster improved help-seeking behaviour.

Published: April 2024

Parkinson’s disease (PD) is a neurodegenerative disorder distinguished by the presence of progressive deterioration of the nervous system and is prevalent among the elderly population. The pathological hallmark of PD involves the accumulation of the protein alpha-synuclein and neuronal inflammation, which leads to the degeneration of dopaminergic (DAergic) neurons. In the present study, neuroprotective effect of combinational extract of Ficus religiosa (F. religiosa) and Oxalis corniculata (O. corniculata) L. in a mouse PD model. By giving Rotenone (ROT) on alternate days subcutaneously for 21 days, a disease model was generated. Extracts were administered individually as well as in combination orally 1 hour before ROT (1.5 mg/kg, s.c.) administration. On day 22nd, after sacrificing of animals neurochemical assays [total protein content (TPC), malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), nitrite (NO)], neurotransmitter analysis, and histology of the brain were performed. Results of the study showed a significant increase in the level of TPC, CAT, SOD, GSH, and dopamine in substantia nigra and a significant reduction of MDA, NO, and glutamate after administration of F. religiosa and O. corniculata in combination (200 + 500 mg/kg, p.o.) in a ROT induced model. This study demonstrated that a combination of F. religiosa and O. corniculata improved motor symptoms and reduced dopaminergic neuron death in mice challenged with ROT.

Authors: Hema Hema , Panigrahi Naresh
Published: April 2024

An accurate, sensitive, and linear liquid chromatographic tandem mass spectrometric method was developed for the quantification of asciminib in human plasma. Voriconazole, internal standard (IS), and asciminib were isolated from the plasma samples by C18-cartridges. Chromatographic isolation was processed with Atlantis/dC18 (2.1 × 100 mm, 3 μm) stationary phase and a mobile solvent system of formic acid (0.1%) and methyl alcohol (20:80, v:v), conveyed at a 0.7 ml/minute flowing rate. Analytes were quantified by ionization in a positive approach with electrospray ionization at the mass transitions of (m/z): asciminib, 450.11/239.09, and voriconazole (IS), 350.3/281.1. No interference by constituents of plasma blank or other components was detected. The association between asciminib concentration levels and their respective peak response fractions to voriconazole was rectilinear between 39.0 and 1,586.0 ng/ml. Intraday and interday precisions were ≤4.79% for asciminib. The interday bias was between −4.28% and 5.76%, and the intraday bias was −3.75% and 4.53%. The mean measured extraction recovery of asciminib was 99.06%. The recovery of IS was 98.34%. Asciminib was subjected to long-term, bench-top, freeze-thaw, short-term stability, dry extract, auto-sampling, and stock solution stability at Low quality control and High quality control levels, and it was stable at all these conditions. The established technique can be utilized for the regular quantification of asciminib in plasma samples in industries, forensic laboratories, and clinical research organizations.
Emergence of brain-like mirror-symmetric viewpoint tuning in convolutional neural networks
Authors: Farzmahdi Amirhossein , Zarco Wilbert , Freiwald Winrich A , Kriegeskorte Nikolaus , Golan Tal
Published: April 2024

Primates can recognize objects despite 3D geometric variations such as in-depth rotations. The computational mechanisms that give rise to such invariances are yet to be fully understood. A curious case of partial invariance occurs in the macaque face-patch AL and in fully connected layers of deep convolutional networks in which neurons respond similarly to mirror-symmetric views (e.g. left and right profiles). Why does this tuning develop? Here, we propose a simple learning-driven explanation for mirror-symmetric viewpoint tuning. We show that mirror-symmetric viewpoint tuning for faces emerges in the fully connected layers of convolutional deep neural networks trained on object recognition tasks, even when the training dataset does not include faces. First, using 3D objects rendered from multiple views as test stimuli, we demonstrate that mirror-symmetric viewpoint tuning in convolutional neural network models is not unique to faces: it emerges for multiple object categories with bilateral symmetry. Second, we show why this invariance emerges in the models. Learning to discriminate among bilaterally symmetric object categories induces reflection-equivariant intermediate representations. AL-like mirror-symmetric tuning is achieved when such equivariant responses are spatially pooled by downstream units with sufficiently large receptive fields. These results explain how mirror-symmetric viewpoint tuning can emerge in neural networks, providing a theory of how they might emerge in the primate brain. Our theory predicts that mirror-symmetric viewpoint tuning can emerge as a consequence of exposure to bilaterally symmetric objects beyond the category of faces, and that it can generalize beyond previously experienced object categories.

Published: April 2024

Irisin, released from exercised muscle, has been shown to have beneficial effects on numerous tissues but its effects on bone are unclear. We found significant sex and genotype differences in bone from wildtype (WT) mice compared to mice lacking Fndc5 (knockout [KO]), with and without calcium deficiency. Despite their bone being indistinguishable from WT females, KO female mice were partially protected from osteocytic osteolysis and osteoclastic bone resorption when allowed to lactate or when placed on a low-calcium diet. Male KO mice have more but weaker bone compared to WT males, and when challenged with a low-calcium diet lost more bone than WT males. To begin to understand responsible molecular mechanisms, osteocyte transcriptomics was performed. Osteocytes from WT females had greater expression of genes associated with osteocytic osteolysis and osteoclastic bone resorption compared to WT males which had greater expression of genes associated with steroid and fatty acid metabolism. Few differences were observed between female KO and WT osteocytes, but with a low-calcium diet, the KO females had lower expression of genes responsible for osteocytic osteolysis and osteoclastic resorption than the WT females. Male KO osteocytes had lower expression of genes associated with steroid and fatty acid metabolism, but higher expression of genes associated with bone resorption compared to male WT. In conclusion, irisin plays a critical role in the development of the male but not the female skeleton and protects male but not female bone from calcium deficiency. We propose irisin ensures the survival of offspring by targeting the osteocyte to provide calcium in lactating females, a novel function for this myokine.

Anti-diabetic Potentials of Cookies from Wheat, Sweet Potato and African Yam Beans (Sphenostylis stenocarpa) Composite Flour Blends
Authors: Olowookere Dele Ayorinde , Malomo Sunday Abiodun
Published: April 2024

The consumption of cookies offered reliable advantages to the consumers, which included but not limited to perfect eating ability, prolong shelf live and acceptability among all nations. This study thus, investigated the antioxidant and anti-diabetic properties of cookies obtained from wheat-African yam bean-sweet potato composite flour blends at different ratios. The African yam bean and sweet potato were thoroughly processed, milled, sieved thereafter mixed with the commercial wheat flour. Four blends were prepared by using the trial mixing ratio and 100% wheat flour and later used to bake cookies. The proximate, amino acid compositions, antioxidant, amylase and glucosidase inhibitory activities as well as physical properties of the composite cookies were examined while panelists were assigned to assess the cookie samples. The results of the proximate composition showed that the composite flour technology had significant (p<0.05) positive effects on the cookies. Meanwhile, the amino acid compositions of the cookies revealed that the cookie samples were of high aromatic and hydrophobic amino acids, respectively with optimum physical properties. No panelist showed a total dislike for the taste of any of the samples. The added soybean seeds flours showed no significant (p<0.05) effect on the acceptability and preference of the samples. Hence, it is possible to produce better protein and high nutritional cookies from these flour blends. We therefore concluded that the cookies rich in antioxidants and anti-diabetic potentials could be produced from wheat-African yam bean-sweet potato composite flour.

Published: April 2024

Castor (Ricinus communis L.) is a major industrial oilseed crop. Because of its numerous uses in the manufacturing of a wide range of industrial uses, castor oil has risen significantly in importance in the global economy. The study examined market integration in major Castor markets in India, including Dhanera, Patan, Kurnool, and Yemmiganur. The co-integration analysis conducted revealed a high level of market integration, as evidenced by the significant positive and negative values of weekly Castor prices across all markets. Unit root tests indicated that the markets were non-stationary, but became stationary when analyzed at the first difference. Further analysis using Johansen's tests identified three cointegrating equations among the markets. The results of the Vector Error Correction Model (VECM) demonstrated long-term price influences between markets. Specifically, Dhanera was found to be influenced by its own price, as well as by prices in Patan and Yemmiganur. Patan, on the other hand, was influenced by its own price, as well as by prices in Dhanera and Yemmiganur. Additionally, Kurnool and Yemmiganur were influenced by prices in neighboring markets.

Introduction: Ficus capensis is a plant used in traditional medicine to stimulate lactation in women and animals in Africa. However, the effects of their extracts on the mammary gland are poorly documented. The objective of the study was to evaluate the effects of Ficus capensis leaves aqueous extracts on NMRI mice milk secretion.
Methodology: This was an experimental animal study using virgin female NMRI mice aged eight to ten weeks. The mice were grouped into for groups of eight mice each. Each group received one of the following products: distilled water, Galactogil™, sulpiride, aqueous extracts (AE) of capensis leaves. Data were analysed and processed using Microsoft Excel 2016 and Stata MP 16 with P ≤ .05 as the significance threshold.
Results: Arborescence of the galactophorous ducts was more developed in the sulpiride lot. Galactogil™, and capensis leaves extracts treated groups showed almost equivalent arborescence with a higher tendency than the distilled water. With histological haematin- eosin staining, the ratio of galactophorous ducts containing secretions to total ducts was higher in the groups of Ficus capensis AE treated group than distilled water (P = .0001). Galactogil™, sulpiride and the group of Ficus capensis extracts each had higher levels of beta-casein in mammary tissue and average prolactinemia than distilled water (P < .01). Mammary tissue stained by immunohistochemistry with anti-prolactin receptor antibodies showed more intensely labelled mammary glands in the sulpiride and Ficus capensis extracts groups. There was no statistically significant difference between average progesteronemia among the different groups.
Conclusion: F. capensis leaves AE administered to virgin female NMRI mice showed lactogenic and mammogenic effects. The extracts were able to increase the nutritional quality of the milk produced, as evidenced by the increase in protein secretion.

The oak leaf fern, Tectaria zeylanica (Houtt.) Sledge, is an endangered fern in India, native to the Southeast Asian region. For the ex-situ conservation of this endangered fern, spores were collected and cultured aseptically on full-strength KC Medium with sucrose at pH 5.8. The spores are monolete with a prominent winged perispore. The exine ruptures at the laesura, and three or four germ filaments grow out, following a Vittaria-type germination pattern. The prothallial development was of the Aspidium type. Adult gametophytes are cordate and much broader than their length. Antheridia develop between 120 and 140 days. They are characteristically 3-celled, with a basal cell, a median cell, and an opercular cell. The female sex organs, archegonia, develop between 150 and 170 days. They are superficial and arranged on the lower side of the prothallus near the midrib and the meristematic region. Fertilization and subsequent development of the sporophytes were observed after four months. The highest percentage of sporophyte formation was observed on KC medium fortified with Kin 0.5 mg/l. Sporophytes had uniseriate, unicellular, and multicellular hairs, similar to those found on adult prothalli. The highest percentage of root formation was observed in the medium with IBA + NAA (1.0 mg/l). The in vitro raised plants showed a 54% establishment during hardening in the field. The present study has established a reproducible protocol for the ex-situ conservation of this endangered oak leaf fern.

Authors: Tewari Vatsala , Behera Swagat Ranjan , Pandey Riya , Panwar Priyanka
Published: April 2024

Summer squash is a short-duration vegetable crop with off-season nature and high economic returns per unit area. However, the early crop growth season encounters a number of abiotic stresses like low temperature and frost, which adversely affect the marketable yield and quality of the fruits. This dependency on natural factors restricts the scope of its profitable cultivation, thereby making it necessary to bring more area under protected cultivation. Coloured plastic mulches are an important component of protected cultivation, which are designed to modify the microclimate at the plant and soil levels so as to increase crop production and productivity, as well as quality of the produce, to meet the demands of the consumers. Keeping these considerations in view, the present field investigation was conducted at the Vegetable Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during the rabi season of 2019-20 to study the effect of different coloured plastic mulches on the growth and yield of summer squash (Cucurbita pepo L.). The experiment comprised nine treatments (bi-coloured plastic mulches) replicated thrice in a randomised block design. Results revealed that use of different coloured plastic films significantly influenced the growth and yield parameters of summer squash. Red coloured plastic mulch (V1) recorded the maximum values for fruit length (30.78 cm), fruit yield plant-1 (1975.8 g), fruit yield plot-1 (39.51 kg) and total marketable fruit yield (365.52 q ha-1), while biodegradable film of silver-black colour (V7) and black plastic mulch (V4) recorded the maximum plant height (cm) and plant spread (cm), respectively. The maximum diameter of the fruit (110.13 mm) was recorded under black coloured plastic mulch. Considering the prevalent climatic conditions of the tarai region of Uttarakhand, red coloured plastic mulch can be recommended for commercial cultivation of summer squash for obtaining higher fruit yields.

O artigo analisa cinco aspectos do romance Torto arado: o espaço-tempo da narrativa; os pares dialéticos que a compõem; a estratégia de estabelecimento das instâncias narrativas; o simbolismo de três objetos ao longo do texto, e, por fim, alguns dos nomes atribuídos às personagens. Busca evidenciar que a terra é categoria central para a análise do romance e demonstrar como um método dialético de interpretação é uma das possibilidades mais produtivas para a tarefa de desvendá-lo. Diferentes relações sociais em um mesmo espaço geográfico são evidenciadas pela memória, a ancestralidade africana e a religião do jarê, bem como por uma lógica de uso comum da terra em contraste com a propriedade privada capitalista dela. Assim, os conflitos em torno dos direitos relativos à moradia, ao trabalho e à terra são eixos fundamentais da narrativa, de onde surgem a consciência das personagens e o seu movimento de luta.
Rompendo com o mundo que Gilberto Freyre criou
Authors: Oliveira Vinicius Rosalvo de
Published: April 2024

Como premissa teórica, o artigo parte de uma perspectiva transnacional para observar dois fenômenos e suas inter-relações. Primeiramente, nos interessa compreender, segundo a conjuntura internacional da emergência dos direitos humanos, o papel de Gilberto Freyre e suas teses na reaproximação entre Brasil e Portugal na década de 1950. Neste ponto, propomos entrecruzar os estudos sobre democracia racial e lusotropicalismo em prol de um entendimento interconectado desses conceitos e suas inter-relações na reconfiguração discursiva desses dois Estados. Em um segundo momento, entendendo o processo de emancipação cultural como estágio fundacional da organização política e do combate ao racismo e ao colonialismo, direcionamos nosso olhar à recepção e crítica das teses freyrianas por vozes do movimento negro brasileiro e lideranças da luta anticolonial em Portugal.

Among binary compounds, there is a high potential for discovery of novel members (polymorphic phases or compounds) of the nitrides of transition metals group due to a pronounced dependence of the oxidation state of the metals (M) on pressure. The power of high pressure–high temperature (HP‐HT) route for synthesis of binary nitrides has already been demonstrated by the discovery of cubic nitrides of the group 4 and 14 elements, of crystalline polymorphs of P3N5, and by reports on formation of four noble metal nitrides. It is anticipated that such HP products exhibit, in addition to enhanced elastic and mechanical behavior, other functional properties making them interesting for industrial applications. Here, HP–HT synthesis research is extended to nitrides of group 5 elements, resulting in the discovery of a novel hard tantalum nitride, exhibiting U2S3 structure: η‐Ta2N3 (Pbnm, a = 8.1911(17) Å, b = 8.1830(17) Å, c = 2.9823(3) Å). The stoichiometry is supported by two independent means, verifying that η‐Ta2N3 is the first thermodynamically stable transition metal nitride with a N:M ratio exceeding 4:3. Due to its high hardness and peculiar texture (needle‐like and granular crystallites), η‐Ta2N3 may find practical applications as a hard fracture resistant material.

Injecting high electronic charge densities can profoundly change the optical, electrical, and magnetic properties of materials. Such charge injection in bulk materials has traditionally involved either dopant intercalation or the maintained use of a contacting electrolyte. Tunable electrochemical charge injection and charge retention, in which neither volumetric intercalation of ions nor maintained electrolyte contact is needed, are demonstrated for carbon nanotube sheets in the absence of an applied field. The tunability of electrical conductivity and electron field emission in the subsequent material is presented. Application of this material to supercapacitors may extend their charge‐storage times because they can retain charge after the removal of the electrolyte.
Orthogonal Transformations on Solid Substrates: Efficient Avenues to Surface Modification
Authors: Nebhani Leena , Barner‐Kowollik Christopher
Published: May 2009

The performance of solid substrates is not only governed by their molecular constitution, but is also critically influenced by their surface constitution at the solid/gas or solid/liquid interface. In here, we critically review the use of orthogonal chemical transformations (so‐called click chemistry) to achieve efficient surface modifications of materials ranging from gold and silica nanoparticles, polymeric films, and microspheres to fullerenes as well as carbon nanotubes. In addition, the functionalization of surfaces via click chemistry with biomolecules is explored. Although a large host of reactions fulfilling the click‐criteria exist, pericyclic reactions are most frequently employed for efficient surface modifications. The advent of the click chemistry concept has led—as evident from the current literature—to a paradigm shift in current approaches for materials modification: Away from unspecific and nonselective reactions to highly specific true surface engineering.
Patterns of reproduction in Malayan silvered leaf monkeys at the Bronx Zoo

Within phylogenetic limits reproductive characteristics of a given species may vary between populations in response to ecological and social factors. For instance, in environments where high quality nutrition is readily available, the onset and speed of reproduction are often accelerated. Other influencing factors might be maternal experience or the sex of the infant. Here we present data on reproductive characteristics for the silvered leaf monkey (Trachypithecus cristatus), a medium‐sized Asian colobine housed at the Wildlife Conservation Society's Bronx Zoo as a one‐male group. To place the species into an appropriate phylogenetic context, we limited our comparison to other colobine species. Demographic data span 21.4 years (October 1985 to March 2007) and derive from 30 adult females (128.0 female years). Detailed behavioral data stem from a 2.2 years study (November 2002 to January 2005; 734 days, 4,225 hr). As in other Asian colobines, receptive periods were short (mean=4.3 days, n=68). This is expected for one‐male groups where receptivity likely indicates, rather than conceals, ovulation. Gestation length was estimated based on a change in the pattern of sexual behavior (mean=194.6 days, n=7). It fell within the range reported for the taxon. Births occurred year round, at an early age (mean=2.9 years, n=8), at short intervals (mean=14.9 months, n=59) in combination with a short lactation (mean 12.1 months, n=9) likely due to the nearly unlimited availability of nutrition in this zoo setting. Primiparous females tended to have a longer first interbirth interval but infant survival rates were similar to multipara possibly due to the absence of predators. Maternal investment was independent of the infant's sex and birth sex ratio was even. Our results emphasize that when interpreted with caution, zoo populations yield realistic reproductive characteristics that can help fill the gap in our knowledge about colobine life history. Am. J.

Zwei Aktivierungen sind besser als eine: Das chirale difunktionelle Guanidin 1, das ein Aminoamid‐Rückgrat enthält, katalysiert die asymmetrische Michael‐Addition unterschiedlichster Substrate unter milden Bedingungen und liefert die Produkte mit exzellenten Stereoselektivitäten. Die Methode ermöglicht außerdem die effiziente Synthese optisch reiner β‐Aminosäureester. Die Guanidingruppe und das NH‐Proton des Amids sind für die doppelte Aktivierung zuständig.

Published: May 2009

The alignment of Cu2+ ions along a modified DNA helix is studied with either hydroxypyridone (H) or bis(salicylaldehyde)ethylenediamine (S‐en) metalated base pairs (MBPs). The conformational motion of H‐MBP leads to the interlinking of the H‐MBPs by an extended Cu‐O network that is ferromagnetic, whereas the conformational freezing of the S‐en‐MBP leads to an ordered pairwise‐stacked arrangement that is weakly antoferrimagnetic.

An amphiphilic polystyrene‐poly(ethylene glycol) (PS‐PEG) resin‐dispersion of nanoparticles of platinum (ARP‐Pt, 4) was developed with a view towards use in catalysis in an aqueous environment under heterogeneous conditions. ARP‐Pt 4 was prepared by the reduction of PS‐PEG‐NH2‐PtCl2(C2H4) 3, which was generated by mixing PS‐PEG‐NH2 1 and Zeise’s salt 2 (K[PtCl3(CH2CH2)]), with benzyl alcohol in water (80 °C, 12 h). Benzyl alcohol was an essential reducing agent for the preparation of Pt nanoparticles with a narrow size distribution (ϕ=5.9±0.75 nm) throughout the PS‐PEG resin, whereas the reduction of 3 with NaBH4 gave Pt nanoparticles with broad size distribution (ϕ=2—150 nm). ARP‐Pt 4 was found to catalyze the aerobic oxidation of a wide variety of alcohols, including non‐activated aliphatic and alicyclic alcohols, in water with atmospheric oxygen or air under heterogeneous conditions, and was reused without loss of its catalytic activity, to achieve a highly environmentally‐friendly reaction.
Reactions of Cationic Gold(I) with Allenoates: Synthesis of Stable Organogold(I) Complexes and Mechanistic Investigations on Gold‐Catalyzed Cyclizations
Authors: Liu Le‐Ping , Hammond Gerald B.
Published: May 2009

The reaction of allenoates with cationic gold(I)—generated in situ from a phosphine gold chloride and a silver salt—formed unusual, room temperature stable vinyl gold(I) lactones under very mild conditions. The scope and limitations for the synthesis of this novel organogold complex was investigated. DFT calculations on the highest occupied molecular orbitals (HOMOs) of allenoates and the natural bond orbital (NBO) charge densities provided an explanation for the limitations. A plausible mechanism for its formation was proposed based on in situ 1H and 31P NMR spectroscopic analyses. Controlled experiments for the cleavage of the gold–carbon bond by electrophiles indicated that this vinyl gold(I) complex is the likely intermediate in the gold‐catalyzed reaction of carbon–carbon multiple bonds.
