Electron-counting in intermetallics made easy: the 18-n rule and isolobal bonds across the Os–Al system
Authors: Miyazaki Ken , Yannello Vincent J. , Fredrickson Daniel C.
Published: May 2017

Electron count is one of the key factors controlling the formation of complex intermetallic structures. The delocalized nature of bonding in metals, however, has made it difficult to connect these electron counts to the various structural features that make up complex intermetallics. In this article, we illustrate how structural progressions in transition metal-main group intermetallics can in fact be simply understood with the 18-n bonding scheme, using as an example series the four binary phases of the Os–Al system. Our analysis begins with the CsCl-type OsAl phase, whose 11 electrons/Os count is one electron short of that predicted by the 18-n rule. This electron deficiency provides a driving force for Al incorporation to make more Al-rich intermetallic phases. In the structures of Os2Al3 (own type) and OsAl2 (MoSi2 type), each additional Al atom contributes three electrons, two of which go towards cleaving Os–Os isolobal bonds, with the third alleviating the original electron deficiency of OsAl. Across the series, the framework of isolobal Os–Os bonds is reduced from a primitive cubic network (n=6, OsAl) to layers of cubes (n=5, Os2Al3) to individual square nets (n=4, OsAl2). Upon adding more Al to form Os4Al13, the Os–Os contacts are further reduced to dumbbells at the interfaces between fluorite-type columns. At this point, the added Al raises the electron count beyond that needed for filled octadecets on the Os atoms; the excess electrons are accommodated by Al–Al bonds. Throughout this work, we emphasize how the 18-n scheme can be applied from structural inspection alone, with theoretical calculations confirming or refining these conclusions.

TiS2 and Lithium Ion Migration in 1T-Li0.94TiS2
Authors: Werth Vanessa , Volgmann Kai , Islam Mazharul M. , Heitjans Paul , Bredow Thomas
Published: May 2017

In many applications it has been found that the standard generalized gradient approximation (GGA) does not accurately describe weak chemical bond and electronic properties of solids containing transition metals. In this work, we have considered the intercalation material 1T-Li
x
TiS2 (0≤x≤1) as a model system for the evaluation of the accuracy of GGA and corrected GGA with reference to the availabile experimental data. The influence of two different dispersion corrections (D3 and D-TS) and an on-site Coulomb repulsion term (GGA+U) on the calculated structural and electronic properties is tested. All calculations are based on the Perdew-Burke-Ernzerhof (PBE) functional. An effective U value of 3.5 eV is used for titanium. The deviation of the calculated lattice parameter c for TiS2 from experiment is reduced from 14 % with standard PBE to −2 % with PBE+U and Grimme’s D3 dispersion correction. 1T-TiS2 has a metallic ground state at PBE level whereas PBE+U predicts an indirect gap of 0.19 eV in agreement with experiment. The 7Li chemical shift and quadrupole coupling constants are in reasonable agreement with the experimental data only for PBE+U-D3. An activation energy of 0.4 eV is calculated with PBE+U-D3 for lithium migration via a tetrahedral interstitial site. This result is closer to experimental values than the migration barriers previously obtained at LDA level. The proposed method PBE+U-D3 gives a reasonable description of structural and electronic properties of 1T-Li

La ética en el sector del alojamiento turístico como fuente de ventaja competitiva / Ethics in the tourist accommodation sector as a source of competitive advantage
Authors: Barquero Cabrero Mario
Published: May 2017

En las últimas décadas, la mayoría de las empresas han desarrollado estrategias de responsabilidad social, como parte integrante de la ética empresarial. El sector del alojamiento turístico, especialmente los hoteles, no es ajeno a esta tendencia. El sector hotelero tiene una especial incidencia –positiva o negativa- sobre los recursos naturales, culturales y sociales de las áreas en las que opera. Las Naciones Unidas y otros organismos son conscientes del potencial que esta actividad tiene para contribuir a minimizar los efectos adversos y participar en la construcción de un planeta más sostenible, por lo que han instado al sector privado a intervenir mediante un comportamiento más responsable y comprometido. En este artículo, tratamos de analizar como las inversiones en RSE y los cambios en las actividades o procesos en los hoteles repercuten sobre los beneficios en el negocio, tanto desde el punto de vista de la consideración y valoración de los inversores, como desde el punto de vista de un turista actual, cada vez más responsable e informado sobre los modelos de gestión de las empresas.
Dramatización y habilidades sociales en educación primaria. Estudio de caso: un alumno, objeto de bullying, con dificultades en asertividad / Dramatization and social abilities in primary education. Case study
Authors: Cruz Cruz Purificación
Published: May 2017

Los programas, tan llenos a veces de objetivos y contenidos de carácter repetitivo,  apartan muy a menudo a la infancia y a la juventud del gozo de la experimentación, del placer de la creación, de la comunicación con los demás, del conocimiento de los valores de los compañeros que les rodean. Es necesario reconocer que nuestra sociedad actual necesita humanizarse, recibir emociones personales positivas. En cambio, cada vez tenemos más chicos y chicas  introvertidos, con problemas de relación y comunicación. Los profesores y profesoras debemos aunar, rectificar, y modificar para que nuestros alumnos sepan incluir en su vida un poquito de creatividad y conocimiento personal. El juego teatral puede ser un maravilloso recurso para trabajar las relaciones personales  y sociales y ayudar especialmente a los alumnos/as que necesitan desarrollar ese tipo de habilidades. Aquí mostramos un estudio de caso donde un alumno con dificultades en habilidades sociales, y que le había llevado a una terrible relación con sus iguales, recibe terapia a través de un grupo de teatro escolar de forma normalizada e inclusiva. Consiguiendo grandes  logros en su desarrollo personal, afectivo y social.  José Cañas nos invita a llevar a cabo la misión de animar al profesorado para que den el paso de pintar de color y calor cada uno de los centros, cada una de las aulas, cada una de las almas de nuestros chicos y chicas.

La revolución artística en Rusia ante la Revolución Soviética / The artistic revolution in Russia in view of the Soviet Revolution
Authors: Ziegler Delgado María Magdalena
Published: May 2017

La Revolución Rusa de 1917 ha sido considerada la causa esencial del despertar de la vanguardia artística de ese país por mucho tiempo. A cien años de los eventos revolucionarios en la escena política y social, se examina el desarrollo de la vanguardia artística rusa previa a 1917, durante los eventos de la Revolución de Octubre de ese año y con posterioridad a ellos hasta 1932. Se demuestra cómo las ideas de vanguardia ya estaban presentes y activas en la Rusia zarista y que la Revolución de 1917 tan sólo otorgaría un marco más reluciente para las propuestas de los artistas de vanguardia. De la misma manera, se demostrará cómo el nuevo status quo soviético terminó ahogando el torbellino vanguardista y estableciendo una metodología de acción y producción en el arte que distaría mucho de la originalidad de la vanguardia anterior a 1917.

Heart of the Matter
Authors: Bochner Arthur P.
Published: May 2017

This mini-manifesto synthesizes premises and foundational principles of an autoethnographic consciousness. Depicting autoethnography as a genre of doubt, I focus on autoethnography's ethical design, its gifts and afflictions, and the ways in which autoethnography troubles and transgresses the boundaries separating scientific and literary modes of truth telling. By encouraging modes of intimate, personal, caring, and self-reflexive expression, autoethnography raises important questions about the meanings and uses of memory, storytelling, truth, and reality. Autoethnography is not a discourse of order, stability, control, and destiny but one of ambiguity, contradiction, contingency, and chance that allows scholars to maintain an emotional and personal connection to their research.
Autoethnography as a Way of Being (Radiophonic)
Authors: Werner Karen
Published: May 2017

Autoethnography is ready to tap into the full creative possibilities of radiophonic space, to reach broader audiences, and to enter more public and popular spaces. And “true story” podcasts need more critical and diverse forms of storytelling; huge audiences are eager for experimentation. Can we ask a methodology, a form of knowledge-making such as autoethnography to be a way of living, of being in relationship to self and other? Yes. And radio adds so much pleasure and expansiveness to the mix.
USP4 inhibits SMAD4 monoubiquitination and promotes activin and BMP signaling

Published: May 2017

SMAD4 is a common intracellular effector for TGF‐β family cytokines, but the mechanism by which its activity is dynamically regulated is unclear. We demonstrated that ubiquitin‐specific protease (USP) 4 strongly induces activin/BMP signaling by removing the inhibitory monoubiquitination from SMAD4. This modification was triggered by the recruitment of the E3 ligase, SMURF2, to SMAD4 following ligand‐induced regulatory (R)‐SMAD–SMAD4 complex formation. Whereas the interaction of the negative regulator c‐SKI inhibits SMAD4 monoubiquitination, the ligand stimulates the recruitment of SMURF2 to the c‐SKI‐SMAD2 complex and triggers c‐SKI ubiquitination and degradation. Thus, SMURF2 has a role in termination and initiation of TGF‐β family signaling. An increase in monoubiquitinated SMAD4 in USP4‐depleted mouse embryonic stem cells (mESCs) decreased both the BMP‐ and activin‐induced changes in the embryonic stem cell fate. USP4 sustained SMAD4 activity during activin‐ and BMP‐mediated morphogenic events in early zebrafish embryos. Moreover, zebrafish depleted of USP4 exhibited defective cell migration and slower coordinated cell movement known as epiboly, both of which could be rescued by SMAD4. Therefore, USP4 is a critical determinant of SMAD4 activity.
Bacilli glutamate dehydrogenases diverged via coevolution of transcription and enzyme regulation
Authors: Noda‐Garcia Lianet , Romero Romero Maria Luisa , Longo Liam M , Kolodkin‐Gal Ilana , Tawfik Dan S
Published: May 2017

The linkage between regulatory elements of transcription, such as promoters, and their protein products is central to gene function. Promoter–protein coevolution is therefore expected, but rarely observed, and the manner by which these two regulatory levels are linked remains largely unknown. We study glutamate dehydrogenase—a hub of carbon and nitrogen metabolism. In Bacillus subtilis, two paralogues exist: GudB is constitutively transcribed whereas RocG is tightly regulated. In their active, oligomeric states, both enzymes show similar enzymatic rates. However, swaps of enzymes and promoters cause severe fitness losses, thus indicating promoter–enzyme coevolution. Characterization of the proteins shows that, compared to RocG, GudB's enzymatic activity is highly dependent on glutamate and pH. Promoter–enzyme swaps therefore result in excessive glutamate degradation when expressing a constitutive enzyme under a constitutive promoter, or insufficient activity when both the enzyme and its promoter are tightly regulated. Coevolution of transcriptional and enzymatic regulation therefore underlies paralogue‐specific spatio‐temporal control, especially under diverse growth conditions.
Regorafenib-induced hypothyroidism and cancer-related fatigue: is there a potential link?
Authors: Pani Fabiana , Massidda Matteo , Pusceddu Valeria , Puzzoni Marco , Massa Elena , Madeddu Clelia , Scartozzi Mario , Mariotti Stefano
Published: May 2017

Objective

Thyroid dysfunction has been reported during Regorafenib (Reg) administration, but no detailed study is presently available.

Design

Prospective, observational cohort study. Patients with documented metastatic colorectal cancer and progression of disease during or within 3 months after the last standard therapy, with no evidence and history of previous thyroid disease were enrolled.

Methods

Twenty-five consecutive patients were evaluated before and 8–50 weeks after initiating Reg therapy by monthly clinical, ultrasound and laboratory (thyrotropin (TSH), free thyroxine (fT4), antithyroglobulin (TgAb) and antithyroid peroxidase (TPOAb)) evaluation.

Results

Thirteen/25 patients (52%) became hypothyroid (TSH: 12.5 ± 4.01 IU/L, range: 4.6–22.0) within 5 months of therapy. TPOAb became detectable (99–155 IU/mL) in 2/25 (8%) patients. Thyroid volume progressively decreased (from 8.6 ± 2.2 mL to 4.9 ± 2.4 mL after 5 months of Reg therapy, P < 0.0001). The progression-free survival (PFS) was longer in patients developing hypothyroidism (43 weeks) than in those remaining euthyroid (17 weeks, P < 0.01). Fatigue (the most common general serious Reg adverse event) was associated with hypothyroidism severity and reversed after levothyroxine therapy (L-T4).

Conclusions

Reg rapidly causes hypothyroidism in about 50% of patients and in a minority of them also triggers thyroid autoimmunity. Reg-induced hypothyroidism was strictly related to fatigue, easily reversed by L-T4 administration and associated to longer survival. These results suggest that prompt recognition of hypothyroidism in patients with severe fatigue may prevent unnecessary Reg dose reduction or withdrawal.
Sprouting strategies and dead ends in anti-angiogenic targeting of NETs
Authors: Carrasco Patricia , Zuazo-Gaztelu Iratxe , Casanovas Oriol
Published: May 2017

Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms that arise from cells of the neuroendocrine system. NETs are characterized by being highly vascularized tumors that produce large amounts of proangiogenic factors. Due to their complexity and heterogeneity, progress in the development of successful therapeutic approaches has been limited. For instance, standard chemotherapy-based therapies have proven to be poorly selective for tumor cells and toxic for normal tissues. Considering the urge to develop an efficient therapy to treat NET patients, vascular targeting has been proposed as a new approach to block tumor growth. This review provides an update of the mechanisms regulating different components of vessels and their contribution to tumor progression in order to develop new therapeutic drugs. Following the description of classical anti-angiogenic therapies that target VEGF pathway, new angiogenic targets such as PDGFs, EGFs, FGFs and semaphorins are further explored. Based on recent research in the field, the combination of therapies that target multiple and different components of vessel formation would be the best approach to specifically target NETs and inhibit tumor growth.
Educación sexual y género en primarias mexicanas ¿qué dicen los libros de texto y el profesorado?
Authors: Rosales-Mendoza Adriana Leona , Salinas-Quiroz Fernando
Published: May 2017

The aim of this research was to review and analyze, from a gender perspective, the sexuality and gender contents included in the textbooks of Natural Sciences, Civics, and Ethics for the fourth, fifth and sixth grade of elementary school; this was done to point out the strengths and weaknesses on how to address these issues. We, likewise, inquired about teacher training in sexuality and gender topics, for which we relied on the testimony of four interviews with primary school teachers from Quintana Roo and Yucatán (two states of the Mexican southeast): two of them were from fifth grade, and two others were from sixth grade. The results showed that the contents of the textbooks reduce the sexuality topic to reproduction, and they do not include eroticism, which is considered relevant in the approach to comprehensive sexuality education. Similarly, these contents transmit heteronormative ideas regarding emotional bonds, and do not fully incorporate the gender perspective, since they fail to denounce the inequality between men and women. Teacher training is deficient and it emphasizes the effect of the hidden curriculum, as stereotypes and prejudices of gender and sexuality are being transmitted.
La ética en la investigación de posgrado

Published: May 2017

This article presents the results of an exploratory-descriptive research with empirical referents. The objective was to document, systematize and evaluate some features of 15 postgraduate theses in education, with the intention to make visible some recurring dishonest practices of students and teachers. The postgraduate programs from which the theses were obtained are located in the metropolitan area of Mexico City. The selection of documents was carried out between July and November 2015. Two Likert scales were used to assess two dimensions separately: 1) content, in which originality, congruence, dominance and relevance of authors, findings and relevant conclusions were considered; and 2) presentation, which examined style, logical structure, spelling and punctuation, citations, references and sources of information. Each indicator was assigned a numerical value and this one was given an evaluative characteristic: 5: excellent, 3: regular and 1: deficient. Subsequently, percentages were obtained. The results indicated that only a third of the theses could be classified as excellent for the quality of the content and the impeccable presentation; a similar percentage were works that fulfilled the necessary but didn’t count with the rigor and originality of the first ones. The remaining papers had serious deficiencies, both in content and in the formal presentation of the document, without achieving the minimum quality demanded by a postgraduate thesis. The analysis of these investigations made it possible to visualize some of the dishonest practices of people graduating from various educational programs and the lack of commitment to their research. The results about the quality of the research in various doctoral programs indicate that there is little responsibility in students, personal tutor and the reviewer. The results allow the authorities of each program to observe the problem and seek practical solutions to solve it.

Published: May 2017

Being able to properly regulate one’s own learning positively impacts student’s academic performance. Hence the relevance of understanding what they are, how they articulate, and how they change learning strategies and motivation patterns across academic training. Our aims are: (a) to describe cognitive / metacognitive learning strategies and motivation patterns used by students (mean and standard deviation); (b) to analyze the correlations between both groups of variables (Pearson’s index correlation); (c) to compare above results according to the basic level (1st year) and the higher level (5th year) of academic training (Student’s t test). The quantitative ex post facto study was based on the Argentine version of the MSLQ (Motivated Strategies Learning Questionnaire), also called MSLQe; it was applied to 114 students of Psychopedagogy. The results showed the following: (a) a varied repertoire of learning strategies and motivation patterns; (b) a greater use of metacognitive strategies for self-regulation, as well as of strategies for time and study environment management, was associated with higher levels of motivational patterns of goal orientation, task assessment, control beliefs, and self-efficacy of students; (c) statistical differences according to the academic cycle: in favor of the students who were beginners in cognitive strategies of review, metacognitive self-regulation, and organization; while the scores were higher for the advanced students in relation to critical thinking. Likewise, regarding the motivation patterns, the advanced students showed more tendencies towards intrinsic orientation goals, whereas the beginners did it in extrinsic motivation goals, beliefs of control and of self-efficacy, and anxiety. It is possible to conclude that the academic formation made possible a hierarchical integration of both superficial and deep strategies, as well as internal and external motivation patterns of the students. Thus, this article contributes to an analysis of cognitive dimensions (cold and warm), as contextually situated (initial and final levels of academic formation), of the learning strategies and motivation patterns of university students.

Спочатку розраховуються атомні маси у відносних одиницях мас, а потім, при необхідності, можна знайти усереднені маси гіпотетичних атомів. Для структур, які складаються із атомів малої різниці мас пропонується використовувати середні маси гіпотетичних атомів. Для структур із великою різницею мас атомів пропонується використовувати зведені маси при дослідженні акустичної вітки коливного спектру особливо в області температур, що нижчі за характеристичну. При визначенні амплітуд коливань кожного сорту атомів у речовині слід використовувати метод розділення цих коливань.

Кваліметрична оцінка органолептичних показників варених ковбас
Authors: Fursik O. , Strashynskiy I.
Published: May 2017

Якість продукції в даний час є ключовою проблемою усіх галузей харчової промисловості. Органолептичний аналіз в сукупності з кваліметричною оцінкою дозволяє швидко і просто оцінити якість сировини, напівфабрикатів і кулінарної продукції, виявити відхилення від рецептури, технології виробництва, що, у свою чергу, дає можливість оперативно вжити заходів стосовно усунення недоліків. Об’єктом дослідження є зразки варених ковбас, в яких провели заміну м’ясної сировини відповідною кількістю гідратованої білоквмісної композиції (20, 30 та 40%). До її складу входять білкові препарати рослинного та тваринного походження, ксантанова та гуарова камідь, а також карбоксиметилцелюлоза. Провівши органолептичний аналіз варених ковбас за рядом показників можна констатувати переваги дослідних зразків № 1 та № 2 над контрольним. Внесення гідратованої композиції завдяки високому вмісту вологи поліпшує консистенцію та підвищує соковитість, що забезпечує приємний смак продукту. У рецептурі № 3 загальна оцінка нижча порівняно із контрольним та дослідними зразками, адже заміна м’ясної сировини значною кількістю гідратованої харчової композиції призводить до утворення рихлої консистенції, що погіршує якісні показники. Використання 30% гідратованої білоквмісної композиції у рецептурі № 2 свідчить про ефективну заміну м’ясної сировини з одночасним здешевленням готового продукту, що у наш час є не менш актуальним.
Особливості використання білково-жирової емульсії в технології реструктурованих шинок
Authors: Kyshenko I.I. , Kryzhova Y.P. , Zhuk V.O.
Published: May 2017

Білково-жирові емульсії, що забезпечують стабільну якість і високий вихід м'ясних продуктів завдяки підвищеним функціонально-технологічним властивостям, знайшли широке застосування у виробництві практично всіх груп м’ясних продуктів, при цьому рівень заміни м’ясної сировини може досягати 48%. Білково-жирові емульсії дозволяють не тільки економити м’ясну сировину, а й раціонально використовувати додаткові джерела білка, жировмісної сировини в складі фаршевих систем у стабілізованому вигляді. Вивчення вітчизняної та зарубіжної літератури показало, що нині існують різні рецептури і способи приготування білково-жирових емульсій (БЖЕ), проте їх застосування обмежене через складну технологію приготування і введення в сировину. I. Zayas та ін. провели порівняльні дослідження властивостей фаршу і готових продуктів при використанні жиру у формі попередньо приготовлених емульсій або у вільному вигляді. Всі характеристики м’ясних фаршевих систем, що містили попередньо приготовлені емульсії, були вищими як за використання остиглого, так і охолодженого м'яса. Частина наукових робіт присвячена застосуванням у складі емульсій поряд з традиційними нетрадиційних жирових і рослинних компонентів та їх використанню в продуктах харчування. Метою роботи було удосконалення технології реструктурованих шинкових виробів в оболонці з індичого м’яса та м’яса свинини шляхом використання БЖЕ з метою збагачення їх амінокислотного та жирнокислотного складу. Використання стандартних методів дослідження та математичних розрахунків дало можливість збалансувати та обґрунтувати амінокислотний склад білкової складової шинки, оптимізувати співвідношення жирних кислот у складі жирової складової. Критерії оптимальності, поставлені в задачі, повністю виконані, оскільки співвідношення індичого та свинячого жирів здатне задовольнити добову потребу в кислотах за кількістю ω-6 та частково за кількістю ω-3, а співвідношення білок:жир:волога в розробленій рецептурі БЖЕ відповідає рекомендованому діапазону 1:(3-5,7: (3:5,7).

Розроблено модельні рецептури м’ясних січених напівфабрикатів функціонального призначення із застосуванням м’яса курчат бройлерів, білкової емульсії на основі білків свинячої шкурки та сухої молочної сироватки, клітковини пшеничної гідратованої, концентрату зеленої маси подорожника та двох видів модифікованих жирів рослинного походження. Досліджено вплив внесення у рецептуру січених напівфабрикатів з м’яса птиці модифікованих жирів різного складу, рослинної сировини та клітковини гідратованої на здатність до протеолізу залежно від рецептурних співвідношень наведених компонентів. Здатність до протеолізу досліджена за допомогою ферментативного гідролізу під дію ферментів пепсину і трипсину в системі in vitro. При проведенні ферментативного гідролізу проаналізовано зразки, що містили в рецептурах білково-жирову емульсію на основі білків свинячої шкурки та сухої молочної сироватки із застосуванням двох видів модифікованих жирів, що містять відповідно ріпакову та пальмову олії як основний складовий компонент. Як контрольну групу прийнято зразки, що відрізнялись відсутністю рослинної сировини (концентрату зеленої маси подорожника) у рецептурі, а також зразки із внесенням білкової емульсії без застосування жиру. Як дослідні зразки представлено зразки модельних січених м’ясних напівфабрикатів із вмістом білково-жирової емульсії на основі білків свинячої шкурки та модифікованих жирів 22,5% з однаковим рівнем внесення гідратованої пшеничної клітковини та концентрату зеленої маси подорожника (18 і 2% відповідно). В ході проведених досліджень вимірювали рівень накопичення продуктів протеолізу у відібраних пробах гідролізату паралельно за двома методиками. Для фіксування гідролізу незамінних амінокислот використовували визначення вмісту тирозину за методом Лоурі. Для визначення загальної частки речовин пептидної та білкової природи у гідролізаті використовували біуретовий метод. За результатами досліджень встановлено, що у контрольних зразках на першій (пепсиновій) стадії протеолізу накопичується більше пептидних сполук, проте мало тирозину. У модельній групі зразків зафіксовано стабільну швидкість накопичення тирозину та перевищення кінцевого вмісту усіх пептидних сполук по завершенню повного циклу протеолізу.

Objective: To evaluate the effect of sitagliptin on somatosensory-evoked potentials (SEPs) and metabolic control in patients with type 2 diabetes mellitus without clinical diabetic neuropathy. Materials and methods: Interventional, prospective, and open study. Patients with less than six months from the diagnosis were included. Examinations of SEPs and laboratory tests at fasting and after food stimulation were performed before and after three months of treatment with sitagliptin (100 mg/day). Results: There was a reduction in the mean levels of HbA1c (P < 0.0001), fasting glucose (P = 0.001), total cholesterol (P = 0.019), and ALT (P = 0.022). An increase in active GLP-1 was found at the end of the study (P = 0.0025). Several SEPs showed statistically significant differences when analyzed before and after treatment with sitagliptin. Conclusion: The results give a glimpse of the possible use of sitagliptin in the treatment of some neurodegenerative conditions of the peripheral nervous system, in addition to its already established role in glycemic control.

O objetivo do estudo foi identificar os fatores associados ao excesso de peso em crianças brasileiras menores de cinco anos. Foram utilizados dados da Pesquisa Nacional de Demografia e Saúde (PNDS) de 2006, um estudo transversal de base domiciliar. O diagnóstico do excesso de peso baseou-se no índice peso-para-altura superior a 2 escores z acima da mediana do padrão antropométrico da Organização Mundial de Saúde - 2006. A população estudada constituiu-se de 4.388 crianças. A prevalência de excesso de peso nas crianças foi descrita segundo variáveis socioeconômicas, demográficas, antropométricas e comportamentais. Foram realizadas análises bruta e ajustada através da Regressão de Poisson e todas foram estratificadas pelo sexo da criança. A prevalência de excesso de peso foi de 6,6%. Após análise ajustada, o índice de massa corporal materno e o peso ao nascer foram associados ao excesso de peso. Além disso, o excesso de peso mostrou-se associado ao tempo de amamentação exclusiva, nos meninos e ao nível socioeconômico e situação conjugal, nas meninas. Enfatiza-se a necessidade da implementação de políticas públicas que atuem, o mais precocemente possível, nos principais determinantes do excesso de peso.

Barley (Hordeum vulgaris L.) is the second most important winter crop in Southern Brazil. The excessive rainfall in this region during the crop-growing season increases the frequency and intensity of foliar fungal diseases. The research aimed to determine the damage function equations (DFE) for the multiple pathosystem of barley brown spot and powdery mildew based on the relationship between grain yield and diseases intensity at different 'BRS Cauê' cultivar growth stages (GS) during 2009 and 2010 growing seasons in Southern Brazil. The experiments were arranged in a randomized complete block design with nine treatments and four replicates. The disease gradients were generated by strobilurins and triazols fungicides rates and number of applications on barley cv. Cauê. The fungicide applications and disease incidence and severity assessments were performed at the 22, 31, 39, 45 and 56 plant GS. The DFE were obtained by variance analysis and linear regression between grain yield and diseases intensity. Significant and negative DFE were obtained and the damage coefficients (DC) varied from 29.48 to 100.08 (2009) and from 36.08 to 113.57kg ha-1 (2010) for incidence, and from 219.5 to 6,276.6 (2009) and 102.3 to 5,292.5kg ha-1 (2010) for severity. The largest damage coefficients were obtained when diseases assessments were made on GS 22 and 31 on both growing seasons evaluated. DFE were used to calculate the economic damage threshold (EDT) as a criterion to indicate the fungicide application moment to control the diseases in cultivars similar to 'BRS Cauê' in Southern Brazil.
MATHEMATICAL ANALYSIS OF THE ALGORITHMS USED IN MODERNIZED METHODS OF BUILDING MEASUREMENTS WITH RTN GNSS TECHNOLOGY
Authors: Krzyżek Robert
Published: May 2017

The use of RTN GNSS surveying technology (Real Time Kinematic Global Navigation Satellite System) for direct measurements of building structures is extremely difficult, and often impossible. Therefore, the real-time technology is supported by indirect methods of measurements. One such solution is the method of line-line intersection. Having determined the position (the coordinates) of the so-called base points on the extension of the wall faces of a building, and having calculated the coordinates of intersection of the lines of relationships between the base points, the coordinates of corners of a building structure are obtained, which are relatively unreliable. In order to increase the reliability of these coordinates, the author proposes to add an innovative solution called vector translation to the classical method of line-line intersection. This paper proves the thesis on the increased reliability of determining the coordinates of corners of buildings by conducting an appropriate mathematical analysis of these formulas, using the algorithm developed by the author. The performed analysis shows that this innovative solution results in a smaller difference between the adjusted coordinates relative to the theoretical ones, than the difference captured from the "raw" measurement results with respect to the theoretical values.
Protecting Ecosystems by way of Biological Control: Cursory Reflections on the Main Regulatory Instruments for Biological Control Agents, Present and Future
Authors: Albert Reece , Moolman Jurie
Published: May 2017

Although there are numerous threats to ecosystems and the resultant ecosystem services, alien and invasive plants (AIP) have been identified as being one of the major causes of ecosystem destruction. In addressing the threat of alien and invasive plants through the use of various mechanisms, the regulatory framework imposed by legislation is key in ensuring that that controlling AIPs does in fact not do more harm than good. One such control mechanism, which has the potential to do wonders or wreak havoc if not adroitly implemented, is that of using biological control agents. This contribution provides a brief overview on the three main regulatory instruments used to control biological control agents in South Africa, namely the Conservation of Agricultural Resources Act 43 of 1983, the Agricultural Pests Act 36 of 1983 and the National Environmental Management: Biodiversity Act 10 of 2004.  It also considers possible future developments on the regulation of biological control agents.
Prisoner Transfer to South Africa: Some of the likely Challenges ahead
Authors: Mujuzi Jamil D
Published: May 2017

Official and unofficial reports indicate that the South African government is in the process of entering into prisoner transfer agreements or making prisoner transfer arrangements. This comes after many years of reluctance on the part of the government to sign a prisoner transfer agreement or enter into any prisoner transfer arrangement. The reason for this change of position is not clear. In this article the author demonstrates what he considers to be the factors behind this change and discusses the issues that South Africa is likely to grapple with when the process of transferring offenders to South Africa commences.
All Roads lead to Property: Pashukanis, Christie and the Theory of Restorative Justice
Authors: Koen Raymond
Published: May 2017

Nils Christie is acknowledged generally as the theoretical founding father of restorative justice. Evgeny Pashukanis may be taken as the premier Marxist theoretician of law. This essay represents an endeavour to read Christie through the lens of Pashukanism, that is, to comprehend the theory of restorative justice developed by Christie in relation to the general theory of law formulated by Pashukanis. The early part of the essay is expository: firstly, it sets out in abbreviated form the fundamental tenets of Pashukanis's so-called commodity form theory of law, with some attention being given to the Pashukanist approach to criminal justice; and secondly, it explains the core elements of Christie's theory of restorative justice, including his critique of western criminal justice and his advocacy of a system of "conflicts as property" as the answer to the crisis of criminality which plagues the western world. The latter part of the essay is critical: it compares and contrasts Christie's proprietary theory of restorative justice with Pashukanis's commodity form theory of law. On the one hand, it is argued that there exists a remarkable theoretical concordance between Christie and Pashukanis in the sense that Christie's idea of criminal conflict as property constitutes a non-Marxist vindication of Pashukanis's analysis of the legal form. On the other hand, it is posited that because Pashukanis proceeds from a Marxist perspective and Christie does not, there remain crucial areas of difference between them, especially as regards the historicity of the legal form, the concept of legal subjectivity, and the role of the state. In the light of these differences the essay concludes with a Pashukanist critique of the Christie thesis, seeking to assess the prospects of restorative justice replacing criminal justice as the generalised mode of disposition of criminal conflicts.
The “Adaptive Management” of a New Nature along the Southern English Coastline
Authors: Empson Rebecca
Published: May 2017

This article explores the tensions between different understandings about how best to manage a stretch of coastline that is threatened by a new piece of land that emerged out of the sea. It looks at the kinds of political worlds this environmental change has engendered and the dynamic shaping of people and places through such change. It argues that in managing the edges of the sea and land in this area, people also forge themselves as new kinds of subjects in a political landscape that is shifting and changing. Contrasting views about how best to manage these changes illuminate the politics of how best to adapt and manage different environments and the people who shape and are shaped by them.
Amphibious Encounters: Coral and People in Conservation Outreach in Indonesia
Authors: Pauwelussen Annet , Verschoor G.M.
Published: May 2017

Drawing on long-term ethnographic research in Indonesia, this article describes a conservation outreach project that attempts to educate and convert local people into coral protectors. Both coral and the sea-dwelling Bajau people appear to be amphibious beings, moving between a changeable land-water interface, and between different, fluidly interwoven ontological constellations. We show that the failure of conservation organizations to recognize the ontologically ambiguous nature of “coral” and “people” translates to a breakdown of outreach goals. Mobilizing the concept of amphibiousness to engage this ambiguity and fluidity, we describe the moving land-water interface as the actual living environment for both coral and people. The notion of amphibiousness, we suggest, has practical and political value, in particular for reconsidering outreach and how it may be reframed as a process involving ontological dialogue. For conservation outreach to become seaworthy, it needs to cultivate an amphibious capacity, capable of moving in-between and relating partly overflowing ways of knowing and being. Providing room for ambiguity, thinking with amphibiousness furthermore encourages suspension of the (Western) tendency to explain the Other, to fix what does not add up. As such, it is of heuristic relevance for the on-going discussions of ontological multiplicity that have proliferated at the intersection between STS and anthropology.

Se realizó un estudio cualitativo con el objetivo de describir las percepciones de profesionales en enfermería sobre la violencia de la pareja íntima contra adolescentes gestantes atendidas en el Hospital de Usaquén (Bogotá, Colombia). Este parte del papel que desempeña enfermería en la detección, prevención y atención de las gestantes víctimas de violencia de sus parejas y surge de una investigación anterior en ese centro de atención, que determinó que las gestantes más jóvenes son las más vulnerables.
El estudio se desarrolló mediante dos grupos focales, con participación de 14 enfermeras que laboran en el hospital. El análisis, de tipo fenomenológico, se realizó con apoyo del software Atlas ti 7. Entre los principales resultados se establece que, según la percepción de las enfermeras, la forma más frecuente de violencia de la pareja íntima contra la adolescente gestante es la psicológica, seguida del abandono y la violencia económica. En cuanto a las necesidades de detección resulta importante ampliar los tiempos de consulta, generar un ambiente de confianza, implementar protocolos de detección inicial y realizar tamizajes. En lo relativo a la prevención, se recomienda iniciar desde la infancia la formación en género y derechos, además de trabajar conjuntamente con la escuela. Para la atención, se considera imperioso el trabajo interdisciplinario. Como barreras se mencionan la negación de las gestantes a denunciar y la amenaza de sus parejas al equipo de enfermería ante la notificación, así como la falta de capacitación del personal de salud.
