A Frobenius–Nirenberg theorem with parameter
Authors: Gong Xianghong
Published: January 2018

The Newlander–Nirenberg theorem says that a formally integrable complex structure
is locally equivalent to the complex structure in the complex Euclidean space.
We will show two results about the Newlander–Nirenberg theorem
with parameter. The first extends the Newlander–Nirenberg theorem to a parametric version,
and its proof yields a sharp regularity result as Webster’s proof for the Newlander–Nirenberg theorem.
The second concerns a version of
Nirenberg’s complex Frobenius theorem and its proof yields a result with a mild loss of regularity.

In this paper we prove the existence and uniqueness of coincident (fixed) points for nonlinear mappings of any number of arguments under a (ψ, θ, φ)-weak contraction condition without O-compatibility. The obtained results extend, improve and generalize some well-known results in the literature to be discussed below. Moreover, we present an example to show the efficiency of our results.
The Impact of the Applied Exchange Rate Regimes on the Internal Balance of Transition Countries
Authors: Vujanić Vlado , Gligorić Dragan
Published: January 2018

One of the key goals of the economic policy makers of every country is to achieve internal and external balance. An unavoidable segment of the analysis concerning the achievement of internal and external balance is certainly the influence of the exchange rate regime applied in a country. European transition countries, despite their similar initial problems and final objectives, applied different exchange rate regimes adapted to the economic circumstances and needs of the country. The paper aims to examine and demonstrate the impact of the applied exchange rate regime on the internal balance of the transition countries. The research encompasses 10 representative transition countries, in the period from 2000-2014. The results of the research, from the aspect of internal balance, confirmed the justification of the application of the floating exchange rate regime in more developed, but not in less-developed, European transition countries. The application of floating exchange rate regimes in less-developed transition countries is associated with a considerably higher average inflation rate, which may be explained by the higher import dependence of lessdeveloped countries and by the consequent transfer of depreciation to price growth.

Published: January 2018

The effects of the mixture of pig skin (PS) and coconut powder (CP) on the gelling and rheological properties of composite gel prepared with squid myofibrillar protein (MP) and lard were studied. The addition of PS and CP gel had significantly improved the water-holding capacity (WHC) and gelling properties of MP-Lard composite gel. Besides, composite gels with an adequate amount of PS and CP gel had a better texture and higher whiteness. The SDS-PAGE results showed that the presence of PS and CP gel did not affect the coagulated proteins in composite gels. The three-dimensional network structures of composite gels containing PS and CP gel were more compact and homogeneous. In general, the mixture of PS and CP could enhance the gel quality of MP-Lard composite gel and it could be used as a fat substitute in surimi products.

Exploring patterns of article use by advanced Korean learners of English and Spanish
Authors: Lee Juyeon , Park Soyoung , Heinz Michael
Published: January 2018

It has been widely recognized in the field of second language acquisition that language learners tend to struggle with the acquisition of articles when their first languages (L1) do not have a similar linguistic system. Thus, various L1 effects on the usage of articles have been studied. In this context, the present study examined how the same L1 (i. e., Korean) would influence article usage in two different languages (i. e., English and Spanish). Specifically, advanced learners of English and advanced learners of Spanish performed a task of consecutive interpreting from Korean to English and Spanish, respectively, and their article usage patterns in English and Spanish were analyzed for comparison. The results show that both groups exhibited high levels of accuracy in the use of English and Spanish articles while major error types were article omission and article misuse, which can be partly attributed to L1 effects. As for differences, the participants in the English group tended to employ other determiners instead of articles, such as possessives, quantifiers, and demonstratives. In Spanish, the tendency to over-use definite articles was stronger than the English group. These differences may be related to certain consecutive interpreting strategies as well as differences in pedagogical approaches of teaching English and Spanish in Korea. Detailed patterns in the use of articles in English and Spanish are compared, and their implications are discussed.

Charge conservation in a gravitational field in the scalar ether theory
Authors: Arminjon Mayeul
Published: January 2018

A modification of the Maxwell equations due to the presence of a gravitational field was formerly proposed for a scalar theory with a preferred reference frame. With this modification, the electric charge is not conserved. The aim of the present work was to numerically assess the amount of charge production or destruction. We propose an asymptotic scheme for the electromagnetic field in a weak and slowly varying gravitational field. This scheme is valid independently of the theory and the “gravitationally-modified” Maxwell equations. Then we apply this scheme to plane waves and to a group of Hertzian dipoles in the scalar ether theory. The predicted amounts of charge production/destruction discard the formerly proposed gravitationally-modified Maxwell equations. The theoretical reason for that is the assumption that the total energy tensor is the sum of the energy tensor of the medium producing the electromagnetic (e.m.) field and the e.m. energy tensor. This means that an additional, “interaction” tensor has to be present. With this assumption, the standard Maxwell equations in a curved spacetime, which predict charge conservation, are compatible with the investigated theory. We find that the interaction energy might contribute to the dark matter.
Error Free Quantum Reading by Quasi Bell State of Entangled Coherent States
Authors: Hirota Osamu
Published: January 2018

Nonclassical states of light field have been exploited to provide marvellous results in quantum information science. Usefulness of nonclassical states in quantum information science depends on whether a physical parameter as a signal is continuous or discrete. Here we present an investigation of the potential of quasi Bell states of entangled coherent states in quantum reading of the classical digital memory which was pioneered by Pirandola (Phys.Rev.Lett.,106,090504,2011). This is a typical example of discrimination for discrete quantum parameters. We show that the quasi Bell state gives the error free performance in the quantum reading that cannot be obtained by any classical state.

Beckham, GK, Olmeda, JJ, Flores, AJ, Echeverry, JA, Campos, AF, and Kim, SB. Relationship between maximum pull-up repetitions and first repetition mean concentric velocity.J Strength Cond Res32(7): 1831–1837, 2018—Mean concentric velocity (MCV) of exercise execution has been used by strength and conditioning professionals to improve exercise technique, provide accurate feedback, and predict exercise 1 repetition maximum. There is still limited research on velocity-based training and currently only one research study on the pull-up exercise. The primary purpose of this research was to determine whether the maximum number of pull-ups an individual can perform can be predicted by the MCV of a single pull-up repetition. Forty-nine healthy men and women were recruited who reported they could do at least 2 pull-ups. Each subject performed a standardized warm-up, then a single pull-up repetition, followed by one set of pull-up repetitions to failure. The GymAware PowerTool, a linear position transducer, was used to measure the MCV of each pull-up repetition. Both the MCV of the single repetition and first repetition of the set to failure were recorded, and the greater of the 2 was used in later analysis. Weighted least squares linear regression was used to estimate the relationship between the single-repetition MCV and maximum amount of pull-up repetitions. We observed a statistically significant linear relationship between the maximum number of pull-ups and the MCV of a single pull-up repetition (y = −6.661 + 25.556x,R2= 0.841). Prediction of the maximum pull-up number by a single repetition rather than testing the maximal pull-up number may improve efficiency and effectiveness of exercise testing batteries for military, police, and other populations.

Hernández-Preciado, JA, Baz, E, Balsalobre-Fernández, C, Marchante, D, and Santos-Concejero, J. Potentiation effects of the French contrast method on the vertical jumping ability. J Strength Cond Res 32(7): 1909–1914, 2018—This study examined the acute effects of the potentiation protocol known as French Contrast Method on the vertical jumping ability measured using a countermovement jump (CMJ). Thirty-one athletes participated in this study (intervention group n = 17 and control group n = 14). The CMJ height was measured using the iOS application My Jump 2.0 before and after the French Contrast protocol, which consisted of 3 sets of isometric partial squats, drop jumps, dynamic half-squats, and hurdle jumps. The CMJ height improved from its baseline values by 5.1 ± 1.1% (p < 0.001, effect size [ES] = 0.27) after the first set, by 6.8 ± 1.8% (p < 0.001, ES = 0.41) after the second set, and by 8.5 ± 2.9% (p < 0.001, ES = 0.44) after the third set. The maximal potentiation value was an increase of 11 ± 6.3% (p < 0.001). The control group decreased its CMJ height from the baseline levels, reaching a significant decrement of −2.1 ± 1.6% (p = 0.047). These findings suggest that the French Contrast Method is a valid strategy to improve the vertical jumping ability. This method can be used after the warm-up as a conditioning activity to acutely enhance the lower body's force and power production.

Published: January 2018

Myotonic dystrophy type 1 (DM1) is an autosomal dominant multisystem disease affecting muscles, the eyes and the endocrine organs. Diabetes mellitus and primary hypogonadism are endocrine manifestations typically seen in patients with DM1. Abnormalities of hypothalamic–pituitary–adrenal (HPA) axis have also been reported in some DM1 patients. We present a case of DM1 with a rare combination of multiple endocrinopathies; diabetes mellitus, a combined form of primary and secondary hypogonadism, and dysfunction of the HPA axis. In the present case, diabetes mellitus was characterized by severe insulin resistance with hyperinsulinemia. Glycemic control improved after modification of insulin sensitizers, such as metformin and pioglitazone. Hypogonadism was treated with testosterone replacement therapy. Notably, body composition analysis revealed increase in muscle mass and decrease in fat mass in our patient. This implies that manifestations of hypogonadism could be hidden by symptoms of myotonic dystrophy. Our patient had no symptoms associated with adrenal deficiency, so adrenal dysfunction was carefully followed up without hydrocortisone replacement therapy. In this report, we highlight the necessity for evaluation and treatment of multiple endocrinopathies in patients with DM1.

Learning points:

DM1 patients could be affected by a variety of multiple endocrinopathies.

Our patients with DM1 presented rare combinations of multiple endocrinopathies; diabetes mellitus, combined form of primary and secondary hypogonadism and dysfunction of HPA axis.

Testosterone treatment of hypogonadism in patients with DM1 could improve body composition.

The patients with DM1 should be assessed endocrine functions and treated depending on the degree of each endocrine dysfunction.

Vector-borne diseases are responsible for > 1 million deaths every year but genomic resources for most species responsible for their transmission are limited. This is true for neglected diseases such as sleeping sickness (Human African Trypanosomiasis), a disease caused by Trypanosoma parasites vectored by several species of tseste flies within the genus Glossina. We describe an integrative approach that identifies statistical associations between trypanosome infection status of Glossina fuscipes fuscipes (Gff) flies from Uganda, for which functional studies are complicated because the species cannot be easily maintained in laboratory colonies, and ∼73,000 polymorphic sites distributed across the genome. Then, we identify candidate genes involved in Gff trypanosome susceptibility by taking advantage of genomic resources from a closely related species, G. morsitans morsitans (Gmm). We compiled a comprehensive transcript library from 72 published and unpublished RNAseq experiments of trypanosome-infected and uninfected Gmm flies, and improved the current Gmm transcriptome assembly. This new assembly was then used to enhance the functional annotations on the Gff genome. As a consequence, we identified 56 candidate genes in the vicinity of the 18 regions associated with Trypanosoma infection status in Gff. Twenty-nine of these genes were differentially expressed (DE) among parasite-infected and uninfected Gmm, suggesting that their orthologs in Gff may correlate with disease transmission. These genes were involved in DNA regulation, neurophysiological functions, and immune responses. We highlight the power of integrating population and functional genomics from related species to enhance our understanding of the genetic basis of physiological traits, particularly in nonmodel organisms.

Published: January 2018

Background: The most common type of neuropathy in adults is carpal tunnel syndrome (CTS) which is caused by compression of the median nerve at the wrist.

Methods: This quasi-experimental study was conducted to determine the efficacy of gabapentin on nerve conduction studies in patients with mild CTS. The patients with mild CTS were randomly allocated into two groups. Group A received naproxen alone (500 mg/day, orally) while group B received both gabapentin (100-300 mg) and naproxen (500 mg/day, orally) for two months. Sensory nerve conduction velocity (SNCV) and distal motor latency (DML) were performed at baseline and two months after treatment.

Results: There were no significant differences between the two groups with regards to the outcome parameters before initiation of intervention. The SNCV and DML showed no significant improvements in group A (p>0.05), whereas for group B the SNCV and DML of the median nerve were significantly improved at two months after treatment (p<0.001).

Conclusion: Gabapentin was found to be effective for SNCV and DML in patients with mild CTS over a two-month period.

Ikan bandeng, Chanos chanos merupakan salah satu ikan ekonomis penting di Asia. Sejak tahun 1995, di Indonesia sebagian besar benih bandeng diproduksi dari hatchery sekitar Dusun Gondol, Bali Utara baik untuk pasar domestik maupun perdagangan internasional. Dalam rangka meningkatkan kualitas benih, perlu dilakukan perbaikan induk secara genetik menggunakan populasi yang unggul. Tujuan penelitian ini adalah mendapatkan data laju pertumbuhan dan variasi genetik induk ikan bandeng yang berasal dari lokasi perairan Aceh, Bali, dan Gorontalo. Pertumbuhan ikan bandeng diamati melalui pengukuran panjang dan bobot benih hingga ukuran 500 g (calon induk), serta variasi genetik diamati menggunakan metode RFLP DNA. Benih dan calon induk masing-masing dianalisis sebanyak 15 ekor. Hasil pengamatan pertumbuhan ikan bandeng mulai dari benih hingga menjadi calon induk, menunjukkan bahwa ikan bandeng dari Aceh dan Bali mempunyai pertumbuhan panjang dan bobot yang relatif lebih tinggi dibandingkan dengan ikan bandeng dari Gorontalo, walaupun secara statistik tidak berbeda nyata (P<0,05). Hasil analisis variasi genetik terdapat lima komposit haplotipe dari empat enzim restriksi yaitu Mbo I, Hae III, Hha I, dan Nla IV pada sekuens cytochrome-b. Jumlah rata-rata restriction site adalah 1-3 haplotipe. Populasi Aceh dan Bali memiliki nilai keragaman genetik yang lebih rendah (0,080 dan 0,000) dibandingkan dengan calon induk dari benih Gorontalo (0,115).Milkfish, Chanos chanos is one of the economically important fish in Asia. Since 1995, milkfish seed mostly produced in Gondol area, Northern part of Bali, and suppleted both domestic and international markets. In order to improve its seed quality the improvement of milkfish broodstock genetic is required through selection of superior population. The aims of this research were to evaluate the growth performance and genetic variation of milkfish populations from Aceh, Bali, and Gorontalo Province. The length and weight of fry up to 500 g was measured as well as the genetic variation was detected using RFLP DNA method. Fry and young broodstock in the DNA analyses were 15 individuals. The results showed that the growth in length and weight milkfish seed from fry to young broodstock (size up to 500 g) from Aceh and Bali was slightly higher than that of Gorontalo, but no significant differences (P>0.05) were observed among the populations. The genetic analysis showed five haplotypes composite from four restriction enzymes i.e., Mbo I, Hae III, Hha I, and Nla IV at on cytochrome-b sequen. The average number of restriction site was 1-3 haplotypes. Aceh and Bali populations have lower genetic variations (0.080 and 0.000) compared to Gorontalo (0.115).
A new thermo-mechanical model for structured soil
Authors: Zhou C. , Ng C. W. W.
Published: January 2018

Although thermo-mechanical behaviour of soil is strongly affected by structure, as far as the authors are aware, none of the existing constitutive models has incorporated structure effects. Consequently, the thermo-mechanical behaviour of a soil with various structures (e.g. reconstituted, intact and recompacted specimens) cannot be captured by using a single set of parameters. In the present study, a new thermo-mechanical elastoplastic model is proposed for structured soil. The model is appropriate for predicting soil behaviour under one-dimensional and triaxial stress conditions. It is assumed that soil structure affects thermo-plasticity through three different mechanisms: (a) structured soil (e.g. intact and recompacted specimens) has a larger preconsolidation pressure than the corresponding reconstituted soil at a given temperature, stress and density condition; (b) thermal softening (i.e. the reduction of preconsolidation pressure with increasing temperature) of structured soil is smaller than that of reconstituted soil; (c) degradation of soil structure contributes to plastic thermal strain. To verify the new model, it is applied to simulate the behaviour of reconstituted, intact and recompacted loess (low-plasticity clay) under cyclic heating and cooling. Experimental results and model predictions are well matched. It is evident that, with a single set of parameters, the proposed model is able to capture cyclic thermal behaviour of a soil with various structures.
Field tests of laterally loaded flexible piles in soil with top cement-treated layers
Authors: Faro Vítor Pereira , Schnaid Fernando , Consoli Nilo Cesar
Published: January 2018

A series of laterally loaded tests on flexible piles inserted in bonded residual soil was conducted. To evaluate the main aspects of shaft mobilisation under lateral loading, a series of tests was performed under two different pile configurations: in naturally bonded residual soil and in artificially top cemented sand layers reinforcing the naturally bonded residual soil. The length to diameter ratio (L/D) of the piles was selected as 20, representing the behaviour of a free-headed, flexible pile. The size of the cylindrical cement-treated sand layers around the pile ranged from 2 D to 4 D and 0·1 L to 0·3 L. The treated layer was a mixture of Osório sand and early-strength Portland cement. Experimental results showed a significant increase in the lateral load performance of flexible piles when the top soil layer was treated with cement. The ultimate lateral load capacity (Hult) increased six fold – from about 50 kN in naturally bonded residual soil to around 300 kN in artificially cemented sand layers embedded in naturally bonded residual soil, and a considerable reduction of the displacements measured at the pile head was observed.
Maintaining and widening the M25 motorway, UK: a private finance case study
Authors: Rubio Francisco J
Published: January 2018

The M25 motorway around London, UK, is one of the busiest in Europe. The current contract for maintaining the route, including widening some sections, was awarded in 2009 under a private finance initiative project amid the global financial crisis. This paper reports on the initial funding challenges for the design, build, finance and operate contract under a traditional private financing arrangement within a constrained financial market. The concerns of the UK’s National Audit Office are discussed together with the approach taken by financial advisors, Highways England and the preferred bidder, Connect Plus. After studying recent developments, it is argued that private financing is an attractive procurement route for infrastructure. The lessons learned and benefits of this financial structure are outlined at a time of decline in projects procured under private finance, particularly after the UK government’s latest infrastructure programme ends in 2021.

We use the Bayesian method introduced by Gallant and McCulloch (2009) to estimate consumption-based asset pricing models featuring smooth ambiguity preferences. We rely on semi-nonparametric estimation of a flexible auxiliary model in our structural estimation. Based on the market and aggregate consumption data, our estimation provides statistical support for asset pricing models with smooth ambiguity. Statistical model comparison shows that models with ambiguity, learning and time-varying volatility are preferred to the long-run risk model. We analyze asset pricing implications of the estimated models.
(Co)educación afectivo-emocional y sexual, para despatriarcalizar la escuela y caminar hacia la igualdad
Authors: Ferreiro Diaz Lola
Published: January 2018

Las raíces de la desigualdad incluyen claves estructurales y simbólicas que se reflejan en la construcción de una subjetividad individual -femenina y masculina-, presidida por dos díadas situadas fuera de nuestro alcance consciente: la abnegación/egocentrismo, y la dirección en la que se emite el impulso agresivo, auto/hetero. Si éstas no se corrigen, difícilmente podremos llegar a conseguir relaciones igualitarias.

El papel de la Escuela, junto con el de las familias, es fundamental, pero se enfrenta con dos dificultades: la falta de medidas estructurales -legislativas y organizativas, en este caso- que promuevan una intervención coeducativa, y la falta de recursos del profesorado, acrecentada por sus propias contradicciones de género. Ambas dimensiones deben ser abordadas de un modo efectivo para permitir la referida intervención en materia de educación para la igualdad.

En este artículo se analizan todas estas dificultades y se intenta aportar algunas ideas para su resolución.

La coeducación introduce el principio de igualdad y la no discriminación a las niñas y a los niños en el modelo educativo; favorece el trato de las niñas como sujetos libres en dicho sistema  pensado para los chicos y los hombres y plantea que los valores de la feminidad formen parte de los valores universales. Este artículo propone el uso de algunas estrategias de intervención coeducativa a través del  Proyecto Educativo de Centro
Coeducación: Feminismo en acción
Authors: Sánchez Bello Ana , Iglesias Galdo Ana
Published: January 2018

La coeducación nace como proyecto político de transformación de una sociedad sexista y, por tanto, desigual, injusta y excluyente; comprometida con un modelo social que rompe definitivamente las relaciones de género jerarquizadas y busca garantizar la posibilidad de una individualidad libremente elegida. Así lo evidenciaban las reformas legislativas que caracterizaron el comienzo del presente siglo pues, al reconocer la existencia de discriminaciones en función del género, insistían en la  necesidad de potenciar la igualdad entre mujeres y hombres en los ámbitos educativos, e introducían diferentes medidas encaminadas a eliminar las desigualdades en función de esta variable.  El proyecto coeducativo bebe de los estudios feministas que, valiéndose del concepto de género para resaltar el origen cultural y de construcción social de estas desigualdades, coloca en un lugar relevante la lucha en contra los estereotipos por su gran poder para definir capacidades, cualidades, intereses y perspectivas de futuro de manera sexuada.

Authors: Pérez Pichardo María Fernanda , Ruz Sahrur Adriana , Barrera Morales Karina , Moo Estrella Jesús
Published: January 2018

INTRODUCCIÓN: los niños con trastorno del espectro autista (TEA) tienen dificultades en las funciones ejecutivas (FE) pero se han sugerido discrepancias entre las medidas directas e indirectas. OBJETIVO: conocer si existen diferencias en las funciones ejecutivas mediante medidas directas e indirectas entre niños con y sin TEA. MÉTODO: se incluyeron 14 varones entre primero y tercero de primaria, 50% con diagnóstico de TEA y 50% con desarrollo neurotípico, seleccionados por emparejamiento en edad y grado escolar. El promedio de edad de la muestra fue de 7.43 (DE 0.98) años. Se aplicaron las pruebas de Evaluación neuropsicológica de funciones ejecutivas en niños (ENFEN) y el Inventario de clasificación comportamental de las funciones ejecutivas (BRIEF). RESULTADOS: se encontraron diferencias significativas en las medidas de las FE indirectas, pero no en las directas, entre los grupos (p < 0.05). Así mismo, las correlaciones entre las medidas directas e indirectas fueron mayores en el grupo con TEA. CONCLUSIONES: los niños con TEA son evaluados con más dificultades en las medidas indirectas de las funciones ejecutivas, pero obtienen puntuaciones similares a los niños con desarrollo neurotípico cuando son evaluados en condiciones estructuradas empleando medidas directas.
Síndrome de Meckel-Gruber en un lactante menor con sobrevida prolongada. Reporte de Caso
Authors: Ramírez Izcoa Alejandro Enrique , Sánchez Sierra Luis Enrique , Alvarenga Calidonio Ramón Humberto , Varela González Douglas
Published: January 2018

El síndrome de Meckel-Gruber es una ciliopatía debida a la disfunción del cilio celular; un trastorno autosómico recesivo letal que se caracteriza por una triada clásica de manifestaciones: displasia renal quística bilateral, meningoencefalocele occipital y polidactilia postaxial. Se presenta el caso de una lactante que al nacer presentó la triada del síndrome de Meckel-Gruber y otras alteraciones, entre las que destacó la aplasia bilateral del nervio óptico. A las 72 horas de vida fue sometida a exéresis de meningoencefalocele occipital con evolución satisfactoria, continuó con tratamiento por infecciones urinarias a repetición debido a displasia quística renal, también padeció infecciones respiratorias y falleció a los 11 meses de vida. Pese a la alta mortalidad del síndrome de Meckel-Gruber en algunos casos, poco frecuentes como éste, la sobrevida de extiende, por lo que es necesario un tratamiento multidisciplinario para tratar las complicaciones.
Sepsis temprana en un recién nacido pretérmino por Pantoea agglomerans: informe de caso y revisión de la literatura
Authors: Gálvez Cuitiva Eduardo Augusto , Peralta Palmezano Juan Javier , Lonngi-Rojas Gabriel
Published: January 2018

INTRODUCCIÓN: Pantoea Agglomerans es un bacilo gramnegativo miembro de la familia Enterobacteriaceae, de distribución ubicua que, bajo ciertas circunstancias, puede tener un comportamiento patógeno en el ser humano. Son pocos los casos de infección neonatal no asociados al cuidado de la salud descritos en la literatura; ninguno de ellos reportado en Colombia.PRESENTACIÓN DEL CASO: niña recién nacida, pretérmino, que desde su primer día presentó una inadecuada adaptación neonatal, con dificultad respiratoria, sepsis y un rápido deterioro clínico, lo cual requirió manejo y soporte en la unidad de cuidados intensivos neonatales. Se aisló por hemocultivos P. agglomerans, susceptible al manejo antibiótico instaurado, con una respuesta adecuada, así como una evolución clínica favorable.CONCLUSIÓN: la sepsis neonatal por P. agglomerans es poco frecuente, por lo que su desenlace dependerá de muchos factores: la detección temprana, la asistencia oportuna y el manejo adecuado que se brinde.

ANTECEDENTES: los estudios de casos y controles son de utilidad cuando se buscan factores de riesgo para enfermedades poco comunes o que tienen un periodo de latencia prologado.OBJETIVO: identificar las principales características del estudio de casos y controles (Ca-Co) para favorecer la disminución de sesgos durante su evaluación o conducción.DESCRIPCIÓN: este diseño se caracteriza por la selección de sujetos con o sin el evento de interés. Éstos se comparan para identificar los factores de riesgo que favorecieron la presencia de este evento. La finalidad de este tipo de estudios es la de inferir una relación causal expresada mediante razón de momios y los intervalos de confianza al 95%.CONCLUSIONES: el diseño de Ca-CO es relativamente fácil y rápido de realizar. Sin embargo, es susceptible a múltiples fuentes de sesgo, las cuales deben de ser minimizadas para obtener mayor confiabilidad de las inferencias obtenidas.

Published: January 2018

First ever record of family Xenasteiidae (Diptera: Brachycera: Cyclorrhapha) from mainland India is provided. Most of the previous records of this family are from coastal sites, as they have usually been found on islands in the Indian and Pacific Oceans. For the first time biology and life stages of Xenasteia are illustrated. Xenasteia members were found associated with an exotic rugose spiraling whitefly (RSW) colony of Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) in the coastal areas of Karnataka in southern India, however no direct obligate association could be diagnosed. Also for the first time Anagyrus sp. (Hymenoptera: Encyrtidae) was recorded from the genus Xenasteia as its solitary parasitoid. Worldwide, this is the first ever report of parasitism associated with any member of this little-known family Xenasteiidae.
