La búsqueda de la identidad. Imaginación, libertad y compromiso
Authors: Yañez Vilalta Adriana
Published: October 2019

This essay is a brief historical review of the concepts of the “double”, the “other”, the “alter ego”. The metaphorical search for identity spreads out through dreams, imagination and creativity. Jean-Paul Richter, Gérard de Nerval, Goethe, Arthur Rimbaud, Thomas Mann, Robert Musil, Rainer Maria Rilke and the french surrealists are some of the authors studied. They contribute to the development of a new conception of the world and of the human being, asserting at each step the power of freedom and action and, at the same time, responsibility, devotion and engagement. Everything implies negation and its double: love and betrayal, ingenuity and grotesqueness, fantasy and pain, sublimity and evil. A universe of echoes and reflections, where one plays with the most secret intimacy. The interior world is a labyrinth and the labyrinth a looking glass.
Nietzsche: creación y sacrificio
Authors: Maldonado Rebeca
Published: October 2019

The will of power can be interpreted as a principle of force and weakness, birth and death, creation and destruction. So, a creative human being is at the same time creator and victim of their own law. This is the reason why their own suffering is the price for them to become a creative individual.
Los avatares del logos
Authors: Flores Farfán Leticia
Published: October 2019

Assuming with Georges Bataille that men is a being who is not in the world “like water within the water”, that is to say, in an immanent and lack of distinction state, but that its destiny is shaped in the permanent significant joint or logos to which its unfinished nature jeopardizes him, we analyze the form in which the mythical story, characterized like a sacred word with symbolic and ontological quality within the perspective of Mircea Eliade, gives account of the wound or the original tear that constitutes the human condition.
Nietzsche y Heidegger, una reflexión sobre los alimentos genéticamente modificados
Authors: Maldonado Rebeca
Published: October 2019

My paper establishes a relation between transgenics foods and several concepts in Heidegger, Nietzsche and Schelling philosophies, in an attempt to answer the following questions: ¿What kind of science emerges with Biotechnology? ¿How is this science connected to Heidegger’s and Nietzsche’s critical thought? My argument is that transgenic food is there an utmost manifestation of a science that pretends to appropriate life and its conditions, and thus imperiling the possibility of any uncovering.
De la técnica a la hermenéutica
Authors: González María Antonia
Published: October 2019

This paper analyzes some relevant issues of the reflection that Martin Heidegger made about the technique. Taking that into consideration, it analyzes two key notions in order to understand the topic: Gestell and Ereignis. It tries to establish the sense in which the Gestell belongs to the essence of the technique as well as the Ereignis belong to the essence of an understanding of the being that is not a metaphysical one and that opens the historicity and another way in which the language is sent. Once is that explained, it analyzes some hermeneutical implications of the Ereignis in the philosophy of Heidegger.
¿Huida o muerte de los dioses?
Authors: Martiarena Óscar
Published: October 2019

The author analyzes F. Hölderlin’s and F. Nietzsche’s proposals about the presence of myths in Western Modernity. In his text, Martiarena examines some of Hölderlin’s theoric approaches and poems, as well as Nietzsche’s fragments in The Gay Sciencie and Thus Spoke Zarathustra. He argues that, even if there are coincidences between these authors that must emphasized, their differences, however, allow us to ask ourselves whether the gods have fled in Modernity, or whether they are dead.
Sócrates y el oráculo de Delfos (una nota sobre Platón, Apología de Sócrates, 20c4-23c1)
Authors: Hülsz Piccone Enrique
Published: October 2019

Starting from a brief restatement of the everlasting “Socratic problem”, this paper deals with a famous passage of Plato’s Apology (surely one of the main sources of the Socratic legend), the story about the Delphic oracle, trying to avoid the false hermeneutic dilemma of fictionalism versus historicism. Two basic points emerge from this exploration: first, that the passage as a whole is designed to offer a portrait of the philosopher, to articulate –indirectly and ironically— a concept of the essence of philosophy as the practice of an aporetic search and selfknowledge; and second, that the narrative itself seems inspired by Heraclitus, and is full of Heraclitean references. The conclusion is the suggestion that both points are connected: Plato’s characterization of philosophy is not only rooted in the figure of Socrates (however the latter is interpreted), but also in ethical and metaphysical ideas expressed undoubtedly by Heraclitus.
Pensamiento crítico versus razón arrogante
Authors: Pereda Carlos
Published: October 2019

In this article, several levels in which can be proposed/presented the old dilemma of liberty and determinism are discussed and which is the task of critical thought or, particularly, of this critical thought that is philosophy. On the one hand, this dilemma is confronted in its metaphysical side. On the other, its epistemological and ethical implications are considered. Along this multiple levels I particularly consider the crash between the point of view of the first person and the third person.

Escepticismo, mecanicismo, teología y alquimia en Robert Boyle
Authors: Silva Carmen
Published: October 2019

The purpose of this article is to approach to the nature of Robert Boyle´s mechanicism and in this way be able to appreciate how this thesis or explanatory model, i.e. the mechanicism, which was fundamental for the philosophers of the XVII century, had important differences among its defenders. In other words, the hypothesis I want to suggest in this work is that mechanicism was, on the one hand, an efficient form to confront aristotelism and to approach to the natural world and, on the other, that in each author of that period we find variations of what each natural philosopher considered mechanicism. It appears to me that in Boyle we can find the following features that define his mechanicism and therefore his natural philosophy; and that he shares some of them with other contemporary philosophers of nature and not others, since in the natural philosophy of each of the authors we can find a distinct form of dealing with the pirronic skepticism, which will result in a specific epistemology and, therefore, both natural philosophy and epistemology were linked in a given theological perspective. In short, that the different combinations of the distinct epistemic as well as theological postures resulted in a specific natural philosophy. In other words, in this work I intend to illustrate all this by exposing some of the epistemic and theological elements that compose the natural philosophy of Robert Boyle and, therefore, approach to the nature of his mechanicism.
La expansión de la responsabilidad humana ante la naturaleza
Authors: Linares Jorge Enrique
Published: October 2019

For the predominant anthropocentric tradition of our civilization, nature and living organisms possess only an instrumental value, and that is the reason why they have not been subjects of ethical consideration until recently. Enviromental ethics has arisen with the purpose to surpass the arbitrary and prepotent anthropocentrism, but it has to consolidate itself as an ethics of the human resposibility towards nature. This responsibility implies to be in charge of the already provoked damages as well as to prevent future alterations caused by the huge capacity of our technological power. My argument in this article is that it is necessary to find a mediation between an anthropocentric and a biocentric ethic that allows us to establish a new ethical paradigm feasible morally as well as politically.
Tranquilidad del alma y poesía en De rerum natura
Authors: Martiarena Óscar
Published: October 2019

A lo largo de su prodigioso poema, Lucrecio nos conduce a través de una naturaleza que en sí misma es poética, a la vez que nos invita a habitarla poéticamente y a tener presente que su contemplación es un ejercicio de la filosofía que busca alcanzar la tranquilidad del alma. Un ejercicio poético de la filosofía que, al tiempo de mostrarnos la visión admirable del todo y de sus partes, busca hacernos capaces de enfrentar con jovialidad el azar de la naturaleza, aunque también el temor, las tinieblas y las supersticiones, las amenazas de la religión, la muerte misma. Así, con “De rerum natura”, Lucrecio abre una posibilidad para nuestra existencia en la que pensamiento y forma, tranquilidad del alma y expresión poética, filosofía y poesía se funden en una unidad indisoluble. Después de mostrar cómo los rasgos esenciales del pensamiento de Epicuro se despliegan a lo largo de “De rerum natura”, el autor sostiene que en el poema, además de mantenerse fiel a su maestro, Lucrecio nos invita a habitar la naturaleza poéticamente, siempre como un ejercicio filosófico encaminado a alcanzar la tranquilidad del alma.
La conciencia de la nihilidad en la poesía de Contemporáneos. Para una hermenéutica de la muerte en la poesía mexicana
Authors: Maldonado Rebeca
Published: October 2019

Este ensayo trata de encontrar las resonancias ontológicas en ‘Muerte sin fin’ de José Gorostiza, en ‘Muerte de cielo azul’ de Fernando Ortíz de Montellano, y en ‘Nostalgia de la muerte’ de Xavier Villaurrutia. En la poesía mexicana está sucediendo una desubstanciación del ser a causa de la muerte, y el ser se funda a sí mismo en el mismo momento que la nada. En este proceso sucede la extinción del “ego”. Estos poetas tratan con los problemas del ser en relación con la nada, de las relaciones entre la vida y la muerte, desde una perspectiva no dualista, pero sí enfocada en las interrelaciones.
Interpretación y traducción de las culturas: las categorías del pensamiento y discurso antropológicos
Authors: Calame Claude
Published: October 2019

The epistemological foundations of cultural and social anthropology -a relation established between a set of native cultural phenomena and our own academic culture- can be seen in terms of translation. Owing to the critical inquiry that anthropology now makes into its own procedures, questions can be raised about the role played by semi-empirical categories, rhetorical phrases and enunciative stances in the formulation of discourses depending on the semiotic triangle.

Telling stories in science communication: case studies of scholar-practitioner collaboration
Authors: Riedlinger Michelle , Massarani Luisa , Joubert Marina , Baram-Tsabari Ayelet , Entradas Marta , Metcalfe Jennifer
Published: October 2019

Reflecting on the practice of storytelling, this practice insight explores how collaborations between scholars and practitioners can improve storytelling for science communication outcomes with publics. The case studies presented demonstrate the benefits of collaborative storytelling for inspiring publics, promoting understanding of science, and engaging publics more deliberatively in science. The projects show how collaboration between scholars and practitioners [in storytelling] can happen across a continuum of scholarship from evaluation and action research to more critical thinking perspectives. They also show how stories of possible futures and community efficacy can support greater engagement of publics in evidence-informed policymaking. Storytelling in collaborations between scholars and practitioners involves many activities: combining cultural and scientific understandings; making publics central to storytelling; equipping scientists to tell their own stories directly to publics; co-creating stories; and retelling collaborative success stories. Collaborative storytelling, as demonstrated in these case studies, may improve the efficacy of science communication practice as well as its scholarship.
The Role of Web Assurance Seals in Nonprofit Giving
Authors: Canada Joseph , Harris Erica E.
Published: October 2019

Using a sample of the 2,000 largest nonprofit organizations in the U.S., we document that the use of web assurance seals is not as commonplace as for-profit e-commerce websites. In particular, we find that only about 14 percent of sample organizations invest in web assurance seals. Those that do provide web seals are larger, less efficient, and spend more on fundraising and information technology. Interestingly, however, our size result weakens for the very largest organizations in our sample. In addition to our contribution to the web assurance literature, we also contribute to donations research in identifying another feature important to donors in the decision to give. Specifically, we find a positive relationship between web seals and donations, indicating that providing this type of assurance attracts more donor support. We believe this is particularly interesting given the relatively few organizations adopting this type of signal in the marketplace for charitable contributions.

What Happens When Formal and Informal Norms Conflict for IT Usage?
Authors: Shoemaker Nikki , Curtis Mary B. , Fayard Louis (Dutch) , Kelly Marie T.
Published: October 2019

Employee ethical perceptions and behavior are shaped by any number of factors that may be complementary or in conflict, such as formal organizational norms that may clash with an individual's personal norms. When formal norms are established to protect the organization, the way employees respond to such conflict can put the organization at risk. We examine how the judgments and intentions of individuals change when formal and informal norms agree or disagree regarding the use of company technology for personal tasks while at work. We varied a company policy (formal norm) and examined participant responses to the policy relative to participants' expected personal norm (informal norm). Participants provided judgments of the ethicality of the behavior and their intention to engage in the same behavior. Both formal and informal norms influence ethicality judgments and intentions. When the norms were in conflict, both norms influence judgments and intentions, but in different ways.
How Significant are the Differences in Financial Data Provided by Key Data Sources? A Comparison of XBRL, Compustat, Yahoo! Finance, and Google Finance
Authors: Boritz J. Efrim , No Won Gyun
Published: October 2019

We compare the financial statement data (excluding footnotes) reported by 105 randomly selected firms in their 10-K filings with data contained in XBRL filings and data reported by three data aggregators/distributors: Compustat, Google Finance, and Yahoo! Finance. We find that 48 percent to 63.2 percent of the 10-K financial statement items available in XBRL filings are not available from the aggregators/distributors. However, aggregator/distributor-provided data contain many financial items that are not in the official 10-K or XBRL filings but could be useful to users. For items included both in XBRL and by aggregators/distributors, all but 0.01 percent of the XBRL data amounts agree with the 10-K filings, whereas 6.5 percent to 7.7 percent of the amounts provided by aggregators/distributors do not, depending on the aggregator/distributor. Most differences are material, and the differences in items used in bankruptcy prediction and earnings quality models result in significant differences in the model results.

Profitability, Product Market Competition, and Stock Returns
Authors: Li Scott
Published: October 2019

This paper finds that product market competition level (measured by Herfindahl Hirschman Index using Fama French 48 industries) affects the performance of zero-cost investment strategies based on gross probability. From 1973 to 2017, the positive returns from such strategy mainly comes from the most competitive industry quintile while a strong reversal exists the second most competitive quintile. The same strategy does not generate any statistically significant returns in concentrated industry quintiles. Out of 25 dependently sorted portfolios on product market competition level and gross profitability, the top performing portfolio comes from the least profitable firms in the second most competitive industry quintile, where 65% of firms are from pharmaceutical and oil industries.
The urgent need for the use of pre-exposure
prophylaxis (PrEP) in the prevention of HIV/AIDS in Sub-Saharan Africa
Authors: Oluwasegun Ayenigbara Israel
Published: October 2019

Human immunodeficiency virus (HIV) is an
infection that came into existence decades back; it spread across the African
countries in the late 1970s, and is currently endemic across the world. HIV is
a major public health problem all over the world, as it has claimed more than
35million lives. There were around 36.9 million individuals living with HIV at
the end of 2017, and Sub-Saharan Africa remains the most affected by HIV
infection with 1 in 25 adults (4.1%) living with the virus, accounting for 70%
of the people living with HIV worldwide. Unfortunately, Sub-Saharan Africa
continues to be the continent with the highest cases of infections and deaths
from HIV/AIDS even after the implementation of various HIV/AIDS prevention
methods. Fortunately, pre-exposure prophylaxis (PrEP) offers the world a novel
way of curtailing the HIV/AIDS epidemic, as PrEP is highly effective for
preventing HIV if it is used as prescribed. This paper discusses the urgent
need for the use of PrEP in the prevention of HIV/AIDS in Sub-Saharan Africa.
It is a review paper in which the meaning of PrEP was discussed, people who
need PrEP were identified, the rationale for the use of PrEP for the prevention
of HIV/AIDS in Sub-Saharan Africa were highlighted, and probable obstacles to
the successful implementation of PrEP for the prevention of HIV/AIDS in
Sub-Saharan Africa were also identified. It was concluded that to achieve the
90-90-90 goals set by UNAIDS to help end the AIDS epidemic in the world, PrEP
offers a new and novel way for HIV prevention, and its implementation across
all African countries is urgently needed for the prevention of HIV/AIDS in
Sub-Saharan Africa.

Authors: Gruia Andreea Karina , Pintilii Radu-Daniel , Marin Marian
Published: October 2019

Creative economies are today one of the fastest-growing economic sectors and an impressive transforming force, than can contribute to increasing territorial, regional or national competitiveness and, therefore, to economic growth and long-term development. The study aims to analyze the contribution of creative economies to the local and regional economy. Quantification of the role of creative economies in the economic profile was made by creating a database, at the level of administrative-territorial unit, with the main economic indicators (number of companies, number of employees, turnover and profit) for the creative economies, according to the NACE classification (Classification of National Economy Activities), for the period 2000-2016. The database was also used for the evolution of the ranks held by each economic sector for the analyzed period and for the development of trend matrices on the evolution of the above indicators, at the four-digit NACE code. The result highlight the importance of creative sector in the dynamics of local and regional economies of the territorial systems.
Performance of Sesame (Sesamum indicum L.) as Influenced by 2,4 – Dichlorophenoxyacetic Acid and NPK Fertilizer
Authors: Eifediyi E.K. , Ogedegbe F.O. , Izuogu N.B. , Adedokun C.A. , Katibi A. , Remison S.U.
Published: October 2019

The Guinea savannah zone of Nigeria is beset by increasing population and infrastructural development, thereby putting pressure on available land with rapidly declining fertility due to low organic matter content, soil erosion, high temperature and seasonal bush burning. Sesame is cultivated in this zone and the yield has remained very low, compared to yield in other parts of the world. This could be attributed to poor nutrient status and poor cultural practices used by peasant farmers. A field experiment was conducted at the Teaching and Research Farm, University of Ilorin, Nigeria, in a southern Guinea savannah zone in 2015 and repeated in 2016 cropping season to determine the effects of 2,4-Dichlorophenoxyacetic acid (2,4-D), a plant growth regulator and NPK fertilizer on the growth and yield of sesame. The experiment was laid out as a factorial arrangement, fitted into a randomized complete block design replicated thrice. The factors imposed were 2,4-D (0, 5 and 10 ppm ha−1) and NPK 15:15:15 (0, 100, 200 and 300 kg ha−1). Data were collected on vegetative traits (plant height, number of leaves, leaf area) and yield components (number of capsules per plant; yield per plant and per hectare). The data were subjected to analysis of variance (ANOVA) using the Genstat statistical package 17th edition and significant means were separated by using the least significant difference at 5% level of probability. The result revealed that using plant growth regulator and NPK fertilizer had significant effects (p<0.05) on plant height (151 cm) and yield per hectare (530 kg/ha). The qualitative and quantitative analysis of the seeds further reaffirmed the presence of bioactive compounds, such as saponins, tannins, flavonoids and phenolic compounds, which are important health promoting food in the seeds.
Physicochemical Traits of Seedless Barberry (Berberis vulgaris L.) Fruits Stored Under Refrigeration as Affected by Heat and Calcium Chloride Treatments
Authors: Moradinezhad F. , Mehregan M. , Jahani M.
Published: October 2019

The loss of chemical characteristics and quality of the fresh seedless barberry fruit during storage and qualitative losses of its dried fruit are the most important postharvest challenges in barberry industry and its exports. The fresh harvested fruit samples were dried using an electrical drier at 50°C to 50% moisture content. Thereafter, the effects of hot water alone (65°C for 45 sec), and hot water + 2% calcium chloride were carried out on the quality maintenance and chemicals during the cold storage of seedless barberry. The results showed that the samples treated with calcium chloride stored at 2°C had the highest TSS over time, whereas the titratable acidity of barberry fruits was not significantly affected by postharvest treatments. Hot water alone or in combination with calcium chloride treatment increased redness and chroma values result in better appearance quality than control. In addition, the treatments reduced the variable L* and thereby enhanced fruit lightness. The highest antioxidant content (% 77.92) was observed in hot water treated samples and the lowest (% 54.28) was obtained on control. Also, the highest amount of anthocyanins and antioxidants were obtained from samples treated with hot water. Only calcium chloride treatment had a significant effect on Ca content of the samples. The results revealed that postharvest application of hot water and calcium chloride treatments improved the appearance quality and nutritional values of fresh seedless barberry fruit, as well as extend the cold storage life, likely due to reduced pathogen contamination.

Published: October 2019

Astragalus armatus Willd. subsp. armatus is an endemic shrub of the Northern Africa. Its cultivation and domestication are very limited because of difficulty with seed germination and establishment. In this study, we investigated some plant morphological characteristics in real time and in situ (leaves, fruit and seeds) of different ecotypes of A. armatus, collected from two sites in Algeria (Arid Steppe of Aïn Naga and Condorcet Mountain), which elevation and climate data are very different. Moreover, the role played by the seed coat in seed dormancy of these two different populations was tested by the effects of the pretreatment and its duration on the performance of seed germination, by considering the final germination percentage (FGP) and the mean germination time (MGT). These parameters are estimated for 10 days in Petri dishes and stored in darkness at (25°C). Pre-sowing treatments included immersion in concentrated sulphuric acid for 30, 60 and 90 min, and immersion in hot water (100°C) for 10 min. Statistical analysis showed that the treatment and the ecotypes effects on both FGP and MGT were highly significant (p< 0.0001). Untreated seeds of both ecotypes of A. armatus failed to germinate (except for a few of Condorcet Mountain ecotypes). For both populations, the most effective treatment was immersion in sulphuric acid for 60 min for the ecotype of Arid Steppe of Aïn Naga, and only 30 min for Condorcet Mountain. An excellent germinative strength is characterized by a higher FGP and a reduced MGT. The morphological characteristic and seed germination could be attributed to intraspecific variations resulting from the natural selection of the same species.

Background

Vitamin D deficiency is repeatedly reported in colorectal cancer (CRC). Since cholesterol and vitamin D share common precursor 7-dehydrocholesterol (7-DHC), it would be important to explore the associations of key vitamin D metabolites and serum lipid parameters in patients with high and low grade CRC. The aim of this study was to analyze relationships between serum 25(OH)D3, 24,25(OH)2D3 and 7-DHC levels and serum lipids in patients with CRC, and to evaluate their potential for prediction of risk for development of high grade CRC.

Methods

We recruited 82 patients CRC and 77 controls. 7-DHC, 25(OH)D3 and 24,25(OH)2D3 were quantified by LC-MS/MS methods.

Results

7-DHC, 25(OH)D3 and vitamin D metabolic ratio (VDMR) were significantly lower in CRC patients than in control group (P<0.001, P<0.010, P<0.050 and P<0.050, respectively). 25(OH)D3 levels were higher in patients with grade I CRC when compared to grade II (P<0.050). All vitamin D metabolites positively correlated with total cholesterol (TC) concentration in CRC patients. 25(OH)D3 was significant predictor of increased CRC risk (P<0.010). After adjustment for TC concentration, 25(OH)D3 lost its predictive abilities. However, 25(OH)D3 remained significant predictor of poorly differentiated type of cancer (P<0.050).

Conclusions

We found significant positive association between vitamin D status and serum total cholesterol. Although low 25(OH)D3 was found to be a significant risk factor for CRC development, the obtained results primarily suggest profound impact of cholesterol level on vitamin D status in CRC. However, our results suggest that low 25(OH)D3 might independently contribute to development of poorly differentiated tumor.

Banyak penelitian terdahulu yang menyatakan bahwa kinerja keuangan seperti struktur modal, pertumbuhan perusahaan dan profitabilitas perusahaan mampu mempengaruhi nilai perusahaan. Hasil tersebut mengkonfirmasi  teori sinyal dalam aktivitas investor di pasar modal Indonesia. Berdasarkan hal tersebut, penelitian ini mencoba untuk membuktikan kembali konfirmasi atas teori sinyal tersebut. Penelitian ini dilakukan pada emiten lembaga keuangan dan perbankan yang telah tercatat di Bursa Efek Indonesia pada akhir tahun 2016, dimulai dengan periode penelitian dari 2014 sampai dengan 2016. Dengan menggunakan teknik purposive sampling, didapatkan 17 emiten sebagai sampel. Kemudian, data dianalisis dengan regresi linier berganda. Hasil penelitian ini menunjukkan secara persial bahwa struktur modal, dan profitabilitas berpengaruh terhadap nilai perusahaan, tetapi tidak untuk pertumbuhan perusahaan. Berdasarkan temuan tersebut dapat dinyatakan pula bahwa untuk kasus penelitian ini teori sinyal dinyatakan cukup efektif terkonfirmasi bekerja pada perusahaan sampel dalam penelitian ini khususnya pada periode pengamatan. Hal ini dicerminkan oleh dua dari tiga varaibel signifikan berpengaruh terhadap nilai perusahaan sebagai cerminan dari tanggapan investor atas sinyal yang diinformasikan oleh perusahaan sampel.

Factores asociados a la toma de decisiones sobre el presupuesto colombiano
Authors: Huertas Jaime Abel , Salinas Adriana Francisca
Published: October 2019

El presente artículo propone un análisis de los debates hechos por los miembros de las Comisiones Económicas del Congreso de Colombia, sobre el Presupuesto General de la Nación de 2002 a 2009, para determinar si las decisiones sobre este han sido tomadas con racionalidad acotada. La base teórica son los planteamientos sobre la toma de decisiones realizados por Lindblom (1959), quien asume el concepto de racionalidad acotada de los agentes propuesto por Simon (1957). La información de las sesiones se analiza con un modelo donde el debate, como variable dependiente, es explicado con covariables relacionadas a las características de los parlamentarios. Con base en un modelo estadístico longitudinal con retiros informativos y covariables dependientes en el tiempo, encontramos factores asociados al debate que nos permiten concluir que las decisiones no fueron tomadas con absoluta racionalidad técnica.
Compression of Spin-Adapted Multi-Configurational Wave Functions in Exchange-Coupled Polynuclear Spin Systems
Authors: Li Manni Giovanni , Dobrautz Werner , Alavi Ali
Published: October 2019

We present a protocol based on unitary transformations of molecular orbitals to reduce the number of non-vanishing coefficients of spin-adapted configuration interaction expansions. Methods that exploit the sparsity of the Hamiltonian matrix and compactness of its eigensolutions, such as the FCIQMC algorithm in its spin-adapted implementation, are well suited to this protocol. The wave function compression resulting from this approach is particularly attractive for anti-ferromagnetically coupled polynuclear spin systems, such as transition metal cubanes in bio-catalysis and, Mott and charge-transfer insulators in solid state physics. Active space configuration interaction calculations on the stretched N2 and square N4 compounds, the chromium dimer, and a [Fe2S2] model system are presented as a proof-of-concept. For the Cr2 case large and intermediate bond distances are discussed, showing that the approach is effective in cases where static and dynamic correlation are equally important. The [Fe2S2] case shows the general applicability of the method.

Published: October 2019

A comparative study of the impact of small, medium-sized, and bulky Δ,Δ-dehydroamino acids (ΔAAs) on the structure and stability of Balaram’s incipient 3₁₀ -helical peptide (1) is reported. Replacement of the N-terminal Aib residue of 1 with a ΔAA afforded peptides 2a–c that maintained the 310-helical shape of 1 in solution. In contrast, installation of a ΔAA in place of Aib-3 yielded peptides 3a–c that preferred a Δ-sheet-like conformation. The impact of the ΔAA on peptide structure was independent of size, with small (ΔAla), medium-sized (Z-ΔAbu), and bulky (ΔVal) ΔAAs exerting similar effects. The proteolytic stabilities of 1 and its analogs were determined by incubation with Pronase. Z-ΔAbu and ΔVal increased the resistance of peptides to proteolysis when incorporated at the 3-position and had negligible impact on stability when placed at the 1-position, whereas ΔAla-containing peptides degraded rapidly regardless of position. Exposure of peptides 2a–c and 3a–c to the reactive thiol cysteamine revealed that ΔAla-containing peptides underwent conjugate addition at room temperature, while Z-ΔAbu- and ΔVal-containing peptides were inert even at elevated temperatures. These results suggest that both bulky and the more synthetically accessible medium-sized ΔAAs should be valuable tools for bestowing rigidity and proteolytic stability on bioactive peptides.

Published: October 2019

Selenium-containing polymers with fascinating functionalities are highly desired but are rarely developed due to their underexplored synthetic methods. Herein, through careful design of monomer structures and polymerization conditions, a series of catalyst-free multicomponent polymerizations (MCPs) of elemental selenium with aliphatic/aromatic diamines and diisocyanides were reported to directly convert elemental selenium to polyselenoureas with long-term stability, good solubility, well-characterized structures, and unique functionalities. The MCPs enjoy wide monomer scope and fast conversion in 1 min, delivering 18 polyselenoureas with high molecular weights (Mws up to 94 600 g/mol) in high yields (up to 99%). Furthermore, the polyselenoureas can be used for the extraction of Au3+ from mixed metal ion solutions in practical conditions with high selectivity, sensitivity (< 1 μg/L), efficiency (> 99.99%), and capacity (up to 665.60 mg·Au3+/g) within 1 min, and elemental gold can be further recovered after pyrolysis of the polymer complexes.
