Published: January 2019

Universal 2 implants may be an alternative to total wrist arthrodesis for the salvage of failed Biaxial total wrist prostheses. We assessed 40 Universal 2 revision implants retrospectively. Fourteen of these wrists were converted to total wrist arthrodeses, and two wrists received a third total wrist arthroplasty after a mean period of 5.5 years. Twenty-four of the Universal 2 implants that remained in situ after a mean follow-up of 9 years (range 4 to 13 years) were re-examined. Sixteen functioned satisfactorily. Patient-Rated Wrist and Hand Evaluation scores and Quick Disabilities of the Arm, Shoulder and Hand scores were 53 and 47, respectively. Twenty-nine patients would choose the Universal 2 again and would also recommend it to other patients. The survival of the revision implants was 60% at a mean follow-up of 9 years.

The correlation between the teardrop angle and anterior lunate facet displacement in plating distal radial fractures
Authors: Teunis Teun , Meijer Sjoerd , Jupiter Jesse ,   DRF-VALCP study group, Rikli Daniel
Published: January 2019

This study aimed to determine the association of teardrop angle and anteroposterior distance with anterior lunate facet displacement and articular congruity before and after anterior plating of distal radial fractures. We included 36 patients with complete intra-articular distal radial fractures with separate anterior lunate facet fragments. On radiographs we determined the teardrop angle and anteroposterior distance. On digital three-dimensional models we measured proximal-distal, anteroposterior and ulnoradial anterior lunate facet displacement, and we outlined the gap surface area. Preoperatively, teardrop angle was highly associated with the extent of anterior lunate facet displacement. Increased anteroposterior distance was mainly associated with articular incongruity after anterior plate fixation. This information may reduce the need of preoperative computed tomography scans in fractures with a normal tear drop angle. This is particularly useful in low-resource settings.
Peripheral arterial disease
Authors: Jain Aman , Clamp Katie
Published: January 2019

Peripheral arterial disease is a chronic condition that is increasingly encountered in primary care. Its symptoms not only affect the patient’s physical wellbeing, but also can have profound effects on mental health. With an ageing population, the prevalence of peripheral arterial disease is likely to increase. Early recognition and optimum medical management can minimise the progression of peripheral arterial disease, allowing patients to lead a pain-free life. This article aims to briefly summarise the common symptoms, suggest tools that can be used to aid diagnosis, and review the current literature on the management of peripheral arterial disease, including surgical options.

Published: January 2019

Background:

The prognostic impact of hyperuricemia and the factors that induce hyperuricemia in cardiovascular intensive care patients remain unclear.

Methods and results:

A total of 3257 emergency department patients were screened, and data for 2435 patients who were admitted to an intensive care unit were analyzed. The serum uric acid level was measured within 15 min of admission. The patients were assigned to a low-uric acid group (uric acid ⩽7.0 mg/dl, n=1595) or a high-uric acid group (uric acid >7.0 mg/dl, n=840) according to their uric acid level on admission. Thereafter, the patients were divided into four groups according to the quartiles of their serum uric acid level (Q1, Q2, Q3 and Q4), and uric acid levels and Acute Physiology and Chronic Health Evaluation II (APACHE II) score. A Kaplan–Meier curve showed a significantly lower 365-day survival rate in a high-uric acid group than in a low-uric acid group, and in Q3 than in Q1 or Q2 and in Q4 than in the other groups. The multivariate logistic regression model for 30-day mortality identified Q4 (odds ratio: 1.856, 95% confidence interval (CI) 1.140–3.022; p=0.013) as an independent predictor of 30-day mortality. The area under the receiver-operating characteristic curve values of the serum uric acid level and APACHE II score for the prediction of 30-day mortality were 0.648 and 0.800, respectively. The category-free net reclassification improvement and integrated discrimination improvement showed that the calculated risk shifted to the correct direction by adding the serum uric acid level to the APACHE II score (0.204, 95% CI 0.065–0.344; p=0.004, and 0.015, 95% CI 0.005–0.025; p=0.004, respectively). The prognosis, including the 365-day mortality, among patients with a high uric acid level and a high APACHE II score was significantly poorer in comparison with other patients.

Conclusion:

The serum uric acid level, which might be elevated by the various critical stimuli on admission, was an independent predictor in patients who were emergently hospitalized in the intensive care unit. The serum uric acid level is therefore useful as a surrogate biomarker for critical patients in the intensive care unit.
Anatomic Study and Reanalysis of the Nomenclature of the Anterolateral Complex of the Knee Focusing on the Distal Iliotibial Band: Identification and Description of the Condylar Strap
Authors: Landreau Philippe , Catteeuw Antoine , Hamie Fawaz , Saithna Adnan , Sonnery-Cottet Bertrand , Smigielski Robert
Published: January 2019

Background:

The capsulo-osseous layer (COL), short lateral ligament, mid–third lateral capsular ligament, lateral capsular ligament, and anterolateral ligament (ALL) are terms that have been used interchangeably to describe what is probably the same structure. This has resulted in confusion regarding the anatomy and function of the anterolateral complex of the knee and its relation to the distal iliotibial band (ITB).

Purpose:

To characterize the macroscopic anatomy of the anterolateral complex of the knee, in particular the femoral condylar attachment of the distal ITB. We identified a specific and consistent anatomic structure that has not been accurately described previously; it connects the deep surface of the ITB to the condylar area and is distinct from the ALL, COL, and Kaplan fibers.

Study Design:

Descriptive laboratory study.

Methods:

Sixteen fresh-frozen human cadaveric knees were used to study the anterolateral complex of the knee. Standardized dissections were performed that included qualitative and quantitative assessments of the anatomy through both anterior (n = 5) and posterior (n = 11) approaches.

Results:

The femoral condylar attachment of the distal ITB was not reliably identified by anterior dissection but was in all posterior dissections. A distinct anatomic structure, hereafter termed the “condylar strap” (CS), was identified between the femur and the lateral gastrocnemius on one side and the deep surface of the ITB on the other, in all posteriorly dissected specimens. The structure had a mean thickness of 0.88 mm, and its femoral insertion was located between the distal Kaplan fibers and the epicondyle. The proximal femoral attachment of the structure had a mean width of 15.82 mm, and the width of the distal insertion of the structure on the ITB was 13.27 mm. The mean length of the structure was 26.33 mm on its distal border and 21.88 mm on its proximal border. The qualitative evaluation of behavior in internal rotation revealed that this anatomic structure became tensioned and created a tenodesis effect on the ITB.

Conclusion:

There is a consistent structure that attaches to the deep ITB and the femoral epicondylar area. The orientation of fibers suggests that it may have a role in anterolateral knee stability.

Clinical Relevance:

This new anatomic description may help surgeons to optimize technical aspects of lateral extra-articular procedures in cases of anterolateral knee laxity.
Sonographic Evaluation of Thyroid Size: A Review of Important Measurement Parameters
Authors: Viduetsky Alexander , Herrejon Christi Lauve
Published: January 2019

An accurate evaluation of thyroid volume, in patients of all ages, is important for the correct diagnosis of a goiter and for sonographic monitoring of thyroid diseases. It is especially important in pediatrics because the linear measurements of a developing thyroid gland do not correlate well with age, sex, or body composition variables. Diverse methods are used to estimate thyroid size and volume. Sonographic volumetry and visual inspection and palpation are used to evaluate the thyroid. Although thyroid size can be easily assessed on physical examination, due to the superficial location of the gland, palpation has low sensitivity and specificity for the management and diagnosis of thyroid disorders. Therefore, thyroid volume measured sonographically is more accurate than thyroid size assessed with a physical examination. Imprecise calculation of thyroid size and volume may lead to false-positive or false-negative diagnoses of thyromegaly, which may result in unnecessary or delayed care.
Combined Embryonal Cell Carcinoma and Granulomatous Orchitis of the Testis
Authors: Martin Abbey , Anderson Sharlette
Published: January 2019

Testicular embryonal cell carcinoma is a germ cell tumor that can be poorly differentiated and quite aggressive. It is a fairly common carcinoma of the testis but is uncommonly found coexisting with the rare inflammatory process of granulomatous orchitis. This case study describes a male in his early 30s diagnosed with embryonal carcinoma of the right testis combined with granulomatous orchitis that was initially found with sonography. The main treatment options are an orchiectomy or chemotherapy. The patient in this case was treated with orchiectomy before the cancer could metastasize to distant organs.
Disc and nerve root findings on lumbar MRI with straightened v
s flexed hips and knees—pilot study
Authors: Espeland Ansgar , Dalen Nina
Published: January 2019

Objective:

To compare disc and nerve root findings, image quality, and pain between supine lumbar MRI positions with straightened v  s flexed hips and knees.

Methods:

In this prospective pilot study, 14 adults with sciatica or suspected lumbar radiculopathy underwent MRI supine with their hips and knees flexed and then straightened. For each position, two experienced radiologists assessed disc contour, location/size of disc herniation, nerve root affection, image quality, image evaluation difficulty, and sagittal angles between the vertebral bodies at each disc level L3-S1. Patients scored pain (0–10) after MRI in each position. We compared MRI assessments and mean pain scores (t-test, log-transformation) between the two positions.

Results:

We found no clear difference in disc bulges, disc herniation, nerve root affection, image quality, or image evaluation difficulty between MRI with straightened v  s flexed knees/hips. Herniation size differed ≤ 0.6 mm between the two positions. Sagittal angles between neighboring vertebral bodies differed ≤3.8°. Mean pain score after MRI with straightened v  s flexed knees/hips was 4.64 v  s 3.29 (p = 0.005).

Conclusion:

In this pilot study, supine lumbar MRI with straightened vs flexed hips/knees showed similar disc and nerve root findings. The straightened position appeared more painful.

Advances in knowledge:

In previous studies, spondylolisthesis increased on supine MRI with straightened v  s flexed lower limbs, but corresponding data on disc findings were lacking. In this pilot study, supine lumbar MRI with straightened rather than flexed hips and knees was more painful and did not improve the diagnosis of disc or nerve root findings.
(Non-)Precautionary Cash Hoarding and the Evolution of Growth Firms
Authors: Boot Arnoud , Vladimirov Vladimir
Published: January 2019

We analyze whether growth firms should delay current investment to hoard cash in order to reduce dilution from external financing. This hoarding motive is the natural counterpart to saving cash as a precaution to help secure funding for future investment opportunities. However, the two motives lead to fundamentally different implications for hoarding and for how cash interacts with key financial and investment decisions. In particular, our paper contributes to understanding why firms choosing private over public financing hoard less, and why product market competition has an ambivalent impact on the public–private choice.

Rendas e Gravatas: moda, identidade e gênero na Imprensa Ilustrada carioca, 1900-1914
Authors: De Oliveira Cláudia Maria de Silva
Published: January 2019

Este texto analisa o modo pelo qual certo estilo feminino de comportamento, associado a formas de vestir adotadas no Rio de Janeiro entre 1900-1914, numa subcultura feminina de grupos de mulheres que entravam no mercado de trabalho ou estavam em vias de profissionalização, era representado em imagens de imprensa cujos autores eram, na maioria, homens. Partimos da hipótese de que o jogo de exposição e representação das mulheres desses grupos, vistas como divergentes da cultura hegemônica burguesa por seu comportamento e vestuário, revelou um dispositivo criativo que subvertia os marcadores de gênero, por meio da manipulação de alguns sinais diacríticos – como roupas, ornamentos e performances públicas – que, aos olhos dos homens da imprensa, expressavam uma identidade feminina nova e híbrida, na qual feminino e masculino pareciam estar justapostos. Nesse jogo, o comportamento e as roupas daqueles grupos de mulheres são metáforas de uma individualidade feminina divergente, bem como dispositivos disruptivos da imagem da mulher frívola e domesticada, própria à época.

To Paint and Die in Arabic: Code-Switching in Rabih Alameddine's Koolaids: The Art of War
Authors: Hout Syrine
Published: January 2019

I focus on multilingual usages, specifically code-switching between English and Arabic, in Lebanese American Rabih Alameddine's 1998 novelKoolaids: The Art of War.While the novel portrays English as the emancipatory language of coming out and self-acceptance for gay Lebanese men living in the United States between the late 1970s and mid-1990s, Mohammad, a painter, only comes to terms with his impending demise by reverting to Arabic during the final stages of his losing battle with AIDS. Drawing on findings from psycholinguistic, sociolinguistic, translation, and medical/neurological studies, I compare and contrast verbal encounters between Mohammad and various Lebanese and American characters to foreground strategies intended to exclude and/or include certain parties, be they characters or readers. While Arabic words actually employed are few, I argue that implied code-switching and the dynamics of speaker(s), interlocutor(s), setting(s), and context(s) establish links among AIDS, Arabic, art, and acceptance of death; Arabic resurfaces, when Mohammad is on his deathbed, as the language of his childhood and even serves as the bridge toward his “afterlife.” The primary theoretical impacts of my reading are twofold: minimal code-switching does not, as some claim, showcase shallow multilingualism, and a language-minded approach adds a new dimension to the definition of Lebanese (Arab) American literature by focusing on the emotional rather than the national/ethnic facets of the embedded native language.
Social and Solidarity Economy and the Transformation of the Cuban Economic Model
Authors: Betancourt Rafael
Published: January 2019

As a consequence of the recent economic reforms, many believe that Cuban society is in reality evolving towards the deconstruction of its social and solidarity
economy and that the economic players are less and less responsible towards the society and the environment. Is it true that we run the risk that greed and
narrow-minded personal pursuit will supplant social values such as righteousness, generosity, compassion, cooperation, empathy and community? This article examines the concept of
the social and solidarity economy (SSE) applied to the Cuban reality, beginning with a characterisation of its economic system based on the mixed or plural economy model. It
concludes that a Cuban SSE is the potential union of those three spheres – public, enterprise and private – comprised of a variety of economic actors – State, associative and
autonomous – that adopts the principles of responsibility towards society and the environment.
Towards a Critique of Marxist Political Economy: Views from the Imperialist Centre
Authors: Schmidt Ingo
Published: January 2019

This article suggests that a critique of Marxist political economy is the key to understanding the development of 20th-century socialisms and the state of global capitalism today. Although such a project requires engagement with Marxist political economy in all parts of the world, this article focuses on Marxist political economy in the imperialist centres. More specifically, it focuses on the theories of imperialism by Hilferding, Luxemburg and Lenin in the years leading up to World War I and the Russian revolution, and the neo-Marxisms and new readings of Marx's Capital during the long post-World War II boom. Critical readings of these different theoretical approaches will allow a re-reading of Marx's Capital focusing on capitalist development from Marx's days to the present.

Published: January 2019

Para que la integración de las Tecnologías de la Información y la Comunicación (TIC) en las aulas universitarias contribuya al desarrollo de procesos pedagógicos de calidad, es necesario que los estudiantes posean un adecuado nivel de competencia digital. Para investigar esta competencia, necesitamos de instrumentos válidos y fiables que permitan recoger información sobre la misma. El principal objetivo que se pretende conseguir es el de identificar las propiedades psicométricas de un cuestionario para medir el nivel de formación en competencia digital de alumnos universitarios, a partir de la autoevaluación que realizan los mismos, de acuerdo a tres dimensiones: conocimientos sobre TIC; manejo de dispositivos, herramientas y servicios TIC; y actitudes hacia las mismas. Todo ello con una muestra compuesta por 656 estudiantes de la Facultad de Educación de la Universidad de Salamanca y de la Universidad de Oporto. Los resultados obtenidos en el análisis de fiabilidad permiten afirmar que este cuestionario es un instrumento con una consistencia interna apropiada, válido para medir los constructos propuestos. De la misma manera, el análisis factorial explora los factores previstos por lo que podemos concluir que el cuestionario diseñado se ajusta al modelo propuesto en sus tres dimensiones.

Published: January 2019

El uso de la gamificación en el sector educativo y específicamente en ambientes e-learning ha tenido un incremento exponencial a partir de 2014. En la actualidad coexisten más de 10.000 aplicaciones móviles (apps) que entremezclan el diseño instruccional, los contenidos educativos y elementos lúdicos de interacción. Sin embargo, no existe un consenso en la comunidad científica acerca de la forma de evaluar y valorar los Aprendizajes Basados en Juegos (GBL) de estas plataformas. La presente investigación tiene por objeto aplicar el Modelo Teórico Integrado de Gamificación en Ambientes E-Learning (E-MIGA) a las 10 apps con mayor número de descargas de la AppStore (iOS) y de la PlayStore (Android), a través de un juicio de 30 expertos en materia de e-learning y gamificación, para transformar dicho modelo teórico en un instrumento de dimensiones e indicadores cuantificable. Posteriormente se aplica una prueba piloto con las puntuaciones extraídas del juicio de expertos a dichas apps. Se colige del test que ninguna de las aplicaciones móviles de educación analizadas ha recibido un puntaje óptimo de 62 puntos, aunque varias de ellas como Memrise, Kahoot y Duolingo cumplen cabalmente con el 72% de los valores expuestos por los indicadores.

Published: January 2019

A pheochromocytoma is a rare tumor that develops from adrenomedullary chromaffin cells and produce ones or more catecholamines, including adrenaline, norepinephrine, and dopamine. On rare occasions a pheochromocytoma is hormonally inactive. Cyanotic heart disease is also a relatively rare pathology. One of its least frequently occurring variants is the single ventricle of the heart. Presumably, in patients with cyanotic heart defects, the occurrence of pheochromocytes and paragangliomas will be higher due to the presence of certain germinative and somatic mutations. In cyanotic heart defects, the development of malignant arrythmias is one of the frequent causes of death. A combination of a pheochromocytoma with a single ventricle of the heart is extremely rare: only eight such cases have been described in the literature. This article describes a young patient with a unique case of a single ventricle of the heart, pheochromocytoma and sustained ventricular tachycardia. The cause of the ventricular tachycardia, in all likelihood, was inappropriate medical care in this case, a prescription for verapamil. The surgical excision of the pheochromocytoma and the referral of the patient for cardiac surgery became possible only after correcting the antihypertensive and antiarrhythmic therapy. Verapamil was replaced with a combination of doxazosin and amiodarone, resulting in relatively satisfactory blood pressure readings and sinus rhythm.

Published: January 2019

Objective. To assess the acupuncture efficiency for conservative treatment and postoperative rehabilitation of patients with spondylolisthesis. Material and Methods. The study group included 42 patients with spondylolisthesis complicated by root syndrome. After surgical intervention the patients underwent treatment consisting of corporal acupuncture and drug therapy (NSAID, diuretics, vitamins, muscle relaxants). The McGill Pain Questionnaire (MPQ), visual analog scale (VAS) and EMG-examinations were used for pain assessment. Results. Drug therapy contributed to pain decreasing in 10 % of patients on the first day of treatment and in 35 % – on the third. Complete relief of pain syndrome occurred in 55 % of patients on the fifth day. The combination of drug therapy and acupuncture provided complete reduction of pain syndrome in 95.4 % of cases during 5 days. Conclusion. It is advisable to apply corporal acupuncture to complex postoperative rehabilitation of patients with spondylolisthesis complicated by root syndrome.

Objective. To study the accuracy of 3D surface reconstruction of human body model by computer optical topography as compared to a multislice computed tomography. Material and Methods. A model of a trunk dorsal surface of a patient with III Grade right side scoliosis in the thoracic spine was used for study. Computer optical topography was performed with a serial installation TODP, METOS Ltd., and multislice computed tomography – with a helical tomograph Siemens Somatom Sensation 4. Results. Comparison of obtained magnitudes of clinical parameters, which are the most significant for diagnostics of spine deformity, revealed that difference in their meanings did not exceed ±0.5 mm for metrical and ±0.5° for angular parameters. Conclusion. Computer optical topography ensures the accuracy of 3D surface reconstruction of human body model, which is comparable to that of a multislice computed tomography, and provides noninvasive and reliable assessment of important clinical parameters of a human body dorsal surface.

MECHANISM OF VERTICAL POSTURE FORMATION AND PARAMETERS OF SAGITTAL SPINOPELVIC BALANCE IN PATIENTS WITH CHRONIC LOW BACK PAIN AND SCIATICA
Authors: Prodan Aleksandr Ivanovich , Radchenko Vladimir Aleksandrovich , Khvisyuk Aleksey Nikolayevich , Kutsenko Vladimir Aleksandrovich
Published: January 2019

Objective.To study parameters of sagittal spinopelvic balance in patients with chronic low back pain and sciatica, and mechanism of vertical posture formation in a sagittal plane.

Material and Methods.Total of 100 patients (32 female and 68 male, mean age 38.7 years) with chronic low back pain and sciatica underwent clinical and radiological examinations. Pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), and global lumbar lordosis (GLL) were measured on lateral standing radiograms. Statistical analysis of the obtained data was performed.

Results.The mean value of PI (50.7°) in patients with back pain and sciatica and in healthy volunteers was almost equal, while SS and GLL were significantly lower in patients, and PT – higher, than those in volunteers. Number of patients with PI ≤ 35 was significantly higher than that of volunteers. Pearson’s correlation coefficient between GLL and PI was 0.916, between GLL and SS – 0.902, and between GLL and PT – 0.326. Vertical posture in patients with chronic low back pain and lumbar sciatica is characterised by backward pelvic rotation relative to hip and by hypolordotic shape of the lumbar spine.

Conclusion.Vertical posture in patients with low back pain and sciatica is determined by a backward rotation of the pelvis, therefore SS and GLL decrease, and PT increases. A prevalence of extremely low values of PI (≤35°) may be considered as a risk factor for lumbar spine degenerative diease. Alteration of vertical posture is a kind of protective mechanism.

Published: January 2019

Total Quality Management (TQM) is a new approach to administration of an institution aimed to achieve long-lasting success due to maximum efficiency of its activity with minimal production costs and steady quality of output products. Practically it took 80 years to realize the necessity to combine two systems of management: of activity and of quality, to meet customers’ requirements. Today quality of medical help is identified as a main goal of state policy in the field of health care. Health institutions need a system of quality management, providing conditions when the quality demanded by a customer is ensured at each step of medical care delivering. Novosibirsk Research Institute of Traumatology and Orthopaedics is among narrow minority of medical institutions which have a quality management system of medical care certified according to International Standard ISO 9001:2000. Implementation of this system based on TQM requirements permitted the administration and the staff of the Institute to proceed from direct control and maintenance of quality of medical care to assured permanent improving of quality thereby promoting a competitiveness of the institution.
Reaganomics: A Watershed Moment on the Road to Trumpism
Authors: Komlos John
Published: January 2019

The socio-economic impact of Reaganomics and its long-run deleterious legacy is documented. The empirical evidence indicates that the tax cuts of 1981 and 1986 failed to have an effect on economic growth. GDP did snap back to its potential but did not accelerate beyond the rates achieved in prior or subsequent decades. The supposed incentives of supply-side economics failed to materialize. People did not work more, they did not save or invest more than they did before, and the benefits trickled down like molasses and got stuck at the very top of the income distribution. Reagan’s presidency was a watershed in US economic development in the sense that it reversed many of the accomplishments of the New Deal and inaugurated an era in which low-skilled men’s wages began a long period of decline. His true legacy is a dual economy that accompanied the hollowing out of the middle class, a more business-friendly regulatory framework for Wall Street that ultimately led to the financial crisis, a stupendous increase in the national debt from 30% to 50% of GDP that put it on a path such that by 2012 it exceeded 100%, anti-statism that contributed to the rise of Trumpism, a remarkable rise in inequality that gave rise to an oligarchy, and the neglect of blue-collar workers who eventually became Hillary Clinton’s “deplorables.” Reagan put the economy on a trajectory that ultimately, even if not inevitably, led to the triumph of Trumpism and an economy of malaise [Johnston, David Cay, 2018.

Changing orientations to heritage language: The practice-based ideology of Sri Lankan Tamil diaspora families
Authors: Canagarajah Suresh
Published: January 2019

The notion of heritage language (HL) has recently been challenged by emerging orientations to language. That languages are always in contact, they are constructed by ideologies, and they don’t have an ontological status challenge traditional notions of HL as primordial, pure, and territorialized. In this article, I draw from data from a qualitative inquiry adopting observations, surveys, and interviews on how families of the Sri Lankan Tamil diaspora community in UK, USA, and Canada define heritage language and competence. I focus specifically on interview data to unveil the language ideologies of community members relating to heritage language and identity. For them, competence means having the ability to align Tamil verbal resources strategically with multimodal semiotic resources and spatial repertoires to accomplish social and cultural communicative activities. For this objective, being proficient in fragmentary verbal resources, receptive and/or conversational skills, low diglossic Tamil, and informal register are deemed satisfactory. Therefore the corpus that is considered as HL is also changing in diaspora contexts to accommodate appropriations from other languages, and metonymic uses, which develop shared indexicality for the community. I label these assumptions as constituting a practice-based ideology of HL. Such an orientation will help us understand HL as a socially constructed and changing construct, while affirming its importance for migrant communities.
The dynamics of Hawaiian speakerhood in the family
Authors: Higgins Christina
Published: January 2019

While the majority of studies onnew speakersfocuses on language use in educational and community contexts, the family is becoming an increasingly relevant site since new speakers are now incorporating their languages into their home life. This article reports on how people of Native Hawaiian ancestry express their speakerhood with regard to their use of ʻŌlelo Hawaiʻi, or the Hawaiian language, in the context of the family. It explores Hawaiians’ stances towards different ways of speaking Hawaiian with regard to authenticity, an issue which has been found to be central among new speakers of minority languages in other contexts. Drawing on interview data with six Hawaiians, this article investigates Hawaiian speakerhood by focusing on how the participants view linguistic authority andtranslanguagingin family settings. The article offers insights into the range of linguistic practices and sociolinguistic authenticities in families that may enhance continued language revitalization efforts.
When X doesn’t mark the spot: the intersection of language shift, identity and family language policy
Authors: Smith-Christmas Cassie
Published: January 2019

This article discusses the reflexive relationship between language shift and identity in the case of Scottish Gaelic on the Isle of Skye, Scotland, demonstrating how (Fishman, Joshua A. 1991.Reversing language shift. Clevedon: Multilingual Matters.) concept of X versus Y as related tolanguageis problematic in this particular context. The article posits that in many ways, the processes by which Gaelic has been alienated from a sense of Scottish identity at the macrolevel are reproduced at the microlevel and discusses the implications of this in terms of Family Language Policy (FLP). Using a nexus analysis approach, this article focuses on a second-generation member – referred to as “Seumas” (the children’s uncle) – of three generations of a Gaelic-speaking family and discusses how, although Seumas appears to see Gaelic as part of his identity in terms of “family” and “heritage”, other identity orientations often take precedence, ostensibly contributing to his high use of English. The article discusses the possible impact that Seumas’ linguistic practices have on the third generation, as well as the double-edged sword nature of using “identity” as a tool in language revitalisation.
Performance Investigate and Analysis of 96 × 10 Gbps DWDM System Using Suitable Rating from Optical Amplifiers
Authors: Kumar Chakresh , Kumar Ghanendra
Published: January 2019

The objective of current work is to design and analyzed 96×10 Gbps DWDM system taking EDFA, SOA, and RAMAN amplifier as an inline amplifiers up to a fiber length of 300 km. The performance of EDFA, SOA, and RAMAN amplifier is measured on the basis of power received, Q-factor, probability of error and BER for various values of fiber distance. In this paper it has been proved that for 96 channels DWDM system at 10 Gbps bit rate, EDFA reveals superior performance as far as the amount of power received is concerned. The value of quality factor (Q-factor) for RAMAN amplifier is almost identical to that of the Q-factor for EDFA and is higher than the Q-factor for SOA till a fiber length of roughly 80 km thereafter SOA reveals somewhat better Q-factor than EDFA and RAMAN amplifier. As far as BER is concerned EDFA and RAMAN amplifier show roughly identical and somewhat lower BER than SOA till a fiber length of roughly 80 km, afterwards SOA reveal somewhat lesser BER till the fiber length of 210 km. In relation to the probability of error P(E), It is analyzed that P(E) remains more or less same for the entire set of optical amplifiers(OAs) but beyond the fiber length of 240 km EDFA shows somewhat lower P(E) than the other two OAs. At the end the Eye diagrams for the three OAs are also figure out.
Radiochemical evidence for the contribution of iron (using 59Fe) remobilization efficiency towards nitrogen (N) and Fe deficiency tolerance in wheat
Authors: Parveen Shamima , Yadav Poonam , Singh Bhupinder
Published: January 2019

Widespread deficiency of soil macro (N) and micro nutrient (Fe) limit crop productivity and nutritional quality of the produce worldwide. Iron is relatively immobile in plants however, its retranslocation can be facilitated by naturally produced chelator in the leaves. Synthesis of these metal-chelators depends on N nutrition of crops. The present study uses 59Fe tracer to measure the contribution of in-plant remobilization (from fully developed 2nd older leaf (OL) to a younger developing 3rd leaf (YL)) of relatively immobile iron towards N and Fe deficiency stress tolerance in Fe efficient bread and Fe inefficient durum wheat. Dual nutrient deficiency of nitrogen and iron induced senescence and hastened the process of chlorophyll degradation and induced a higher 59Fe remobilization from OL to YL. Further, 59Fe retranslocation was also highest under dual nutrient deficiency (N−Fe−). Percent 59Fe retranslocated into the YL of bread and durum wheat, respectively was higher in Fe deficient (N+Fe− and N−Fe−) than Fe sufficient (N+Fe+ and N+Fe−) treatments. Results clearly reveal that Fe deficiency tolerance response under N and Fe deficiency is chiefly determined an efficient Fe uptake and Fe retranslocation, respectively in the bread and the durum wheat.
Special Section: Wittgenstein and Applied Epistemology
Authors: Venturinha Nuno
Published: January 2019

In this introductory piece I summarize the aims and contents of the special section on Wittgenstein and Applied Epistemology, which consists of a selection of papers presented at the 6th Symposium of the International Ludwig Wittgenstein Society that took place at the Nova University of Lisbon in 2017. After explaining the sense in which “applied epistemology” is here employed in connection with Wittgenstein’s thought, brief comments are made on papers by Natalie Alana Ashton, Anna Boncompagni, Marco Brusotti, Michel Le Du, Andrew Lugg, Sofia Miguens, Constantine Sandis, Genia Schönbaumsfeld, and Vicente Sanfélix Vidarte and Chon Tejedor.
The Case for a Feminist Hinge Epistemology
Authors: Ashton Natalie Alana
Published: January 2019

In this paper I make the case for a feminist hinge epistemology in three steps. My first step is to explain hinge epistemologies as contemporary epistemologies that take Wittgenstein’s work in On Certainty as their starting point. My second step is to make three criticisms of this literature as it currently stands. My third step is to introduce feminist epistemologies, which argue that social factors like race and gender affect what different people and groups justifiably believe, and argue that developing a feminist hinge epistemology is both plausible (because of important similarities between the two kinds of views) and desirable (because feminist epistemologies have resources which can help hinge epistemologies to avoid the three problems that I have raised).
Experience and Religious Belief
Authors: Vidarte Vicente Sanfélix , Tejedor Chon
Published: January 2019

In this paper, we defend the view that, although Wittgenstein does not present an epistemology of religion in the sense of the term most commonly found in traditional philosophical texts, he does explore a different understanding of religious epistemology – one that aligns the religious attitude with a particular form of know-how.
Assessing the Medical Staff’s Overall Satisfaction of Patient Safety Culture from a Regional Teaching Hospital in Taiwan

Published: January 2019

This study adds an additional question to the existing Chinese version of the safety attitudes questionnaire (SAQ) to discuss the relationships between the dimensions of the Chinese version of SAQ and the overall perception of the patient safety culture in a regional teaching hospital in Taiwan from the viewpoint of the medical staff. This study uses linear regression with forward selection to assess the perceptions from all of the medical staff by using the data sets in 2015 and 2016. The input variables are eight dimensions, whereas the dependent variable is the overall satisfaction of the patient safety culture in this hospital. The results show that four dimensions are found to significantly affect the overall satisfaction of the patient safety culture. Moreover, it is found that working conditions is the most important dimension in these two years and has the most positive impact on the overall satisfaction. Hospital management needs to pay more attention to working conditions first. In addition to working conditions, safety climate is the other essential dimension identified in both 2015 and 2016; that is, hospital management needs to have a strong and proactive organizational commitment to safety for all of the medical staff to improve the overall satisfaction of the patient safety culture.
