Published: March 2019

In this article, we explore executive education with a consumer’s hat. What must be the key criteria to shortlist a provider for developing our leaders? Why are these criteria important? We will also explore how the provider as well as the consumer can interact in a far more structured manner to create better outcomes for leaders whom they are serving. We do this by posing twelve questions which must be aced to unlock high value from executive education.
Dyes and biological sources in nineteenth to twentieth century ethnographic textiles from Transylvania, Romania
Authors: Petroviciu Irina , Teodorescu Iulia , Albu Florin , Virgolici Marian , Nagoda Eugenia , Medvedovici Andrei
Published: March 2019

Liquid chromatography with UV–Vis and mass spectrometric detection (LC–DAD–MS) was applied to the identification of dyes and biological sources in samples from nineteenth to twentieth century ethnographic textiles from ASTRA National Museum Complex, Sibiu, Transylvania. The objects are part of the Romanian traditional costume and are among the first to be acquired for the museum collections, around 1905. Oral and written information mention such objects as homemade, with nearby materials, while literature mentions a significant number of local vegetal sources as being used for textile dyeing. The analytical protocol developed, based on the combined use of the UV–Vis and mass spectrometric detectors to associate the information and distinguish between major and minor dyes, facilitates a clear attribution of the dyes and biological source/sources used. Other techniques, such as X-ray spectroscopy and FTIR-ATR were successfully used to identify inorganic dyes, which may not be detected by LC–DAD–MS, as was the case of Prussian blue. A large number of biological sources was identified in the studied objects, both local and imported. The local sources identified include dyer’s broom (Genista tinctoria L.), sawwort (Serratula tinctoria L.), young fustic (Cotinus coggygria Scop.), Rhamnus berries, emodin based dyes (Rhamnus, Rheum, Rumex sp.) and woad (Isatis tinctoria L.), in perfect correlation with literature which states that local dyes were still in use in the period under discussion. Carminic acid containing insects (Dactylopius coccus Costa and Porphyrophora sp.) and redwood type Caesalpinia species should be considered a result of trade. Almost all the natural and synthetic dyes detected are frequently mentioned in a collection of recipes published by the Romanian Academy, in 1914. The richness in colours in belts, the use of insect dyes in shirts decoration and the large amount of cotton in shirts are illustrative for the owners’ status. The study provides a better valorisation of the Romanian traditional costume as witness of the rural society at the end of the nineteenth to beginning of the twentieth century and emphasizes the usefulness of chemistry in cultural heritage dedicated applications.
A comparative study of inline and broadside time-domain controlled-source electromagnetic methods for mapping resistive targets on land
Authors: Li Hai , Di Qing-Yun , Xue Guo-Qiang
Published: March 2019

The land-based controlled-source electromagnetic (CSEM) method is an important tool in mapping subsurface resistivity contrast, especially for conductive target embedded in a resistive environment. For resistive targets on land, choosing an appropriate configuration to a specific field observation is quite confusing, due to the lack of systematic comparisons of different methods. We have conducted a comparison between the broadside and inline time-domain CSEM methods, using the short-offset transient electromagnetic (SOTEM) method and multitransient electromagnetic (MTEM) method as representatives respectively. We first compared the resolution of these methods by analyzing the relative target response and the misfit space of the designed models. We found that the inline MTEM method had advantages over the SOTEM method in resolving the thin resistive layer. We have developed a weighted joint inversion scheme to enhance the vertical resolution of the MTEM method. We then applied the methods to the investigation of a giant molybdenum deposit. The orebody, which is the real target of the exploration, does not have a conductivity contrast with its host. However, it sits on top of the granite porphyry, which is resistive compared with its surroundings, and so the granite porphyry becomes the resistive target for EM exploration. The results indicated that both methods are effective in locating large resistive target, yet the MTEM method outperforms the SOTEM method when a thick conductive overburden is presented.
Joint PP and PS plane-wave wave-equation migration-velocity analysis
Authors: Feng Zongcai , Guo Bowen , Huang Lianjie
Published: March 2019

Conventional joint PP and PS velocity analysis is based on ray tomography. We develop a joint PP and PS wave-equation migration-velocity-analysis method using plane-wave common-image gathers (CIGs) to produce accurate P- and S-wave velocity models. The objective function of our new method consists of three terms: The first and second terms penalize the moveout residuals computed from PP and PS plane-wave CIGs, respectively, and the third term constrains the nonzero relative depth shifts between the PP and PS migration images. The moveout of plane-wave CIGs is automatically picked using a semblance analysis method, and the relative depth shifts between the PP and PS images are automatically computed using dynamic warping or manually picking the depths of certain primary reflectors. The moveout residuals and the relative depth shifts are transformed into weighted image perturbations, and they are then projected into the velocity models to update the P- and S-wave velocity models using the scalar-wave equations and their linearized forms. Numerical tests with synthetic and multicomponent field data demonstrate that our method can simultaneously invert for accurate P- and S-wave velocity models for elastic migration.
Lithogeomorphological facies analysis of Upper Miocene coal-prone fluviodeltaic reservoirs, Northern Malay Basin
Authors: Babikir Ismailalwali A. M. , Salim Ahmed M. A. , Ghosh Deva P.
Published: March 2019

The Group E stratigraphic unit is a significant gas producer in the Northern Malay Basin. However, due to the thinly bedded nature of the sandstone reservoirs, thick shale, and abundant coal beds, accurate seismic attributes interpretation of lithology and fluid prediction has been a daunting task. To address this problem, we have conducted an integrated seismic sedimentology workflow using spectral decomposition, color blending, waveform classification, prestack seismic inversion, and stratal slicing to characterize the lithogeomorphological facies of the coal-bearing reservoirs. On spectral decomposition and waveform classification maps, we clearly identified depositional elements such as the distributary channel, distributary mouth bar, subaqueous levee, and interdistributary fill. We computed the elastic properties through prestack seismic inversion to obtain good lithology discrimination between coal and gas-charged sandstone. Both lithologies are characterized by low acoustic impedance, but the compressional to shear velocity ratio ([Formula: see text]) of coal is high compared to gas-charged sandstone. The current interpretation indicated that the Group E interval was deposited in a delta plain setting. The varying flow directions of the distributary channels in the area support the hypothesis that describes the Malay Basin during Miocene time as a narrow gulf, connected to an open sea to the south and flanked by deltas and fan deltas.
Family-inclusive practice in a psychiatric intensive care unit

Published: March 2019

Aims and Method

The National Institute for Health and Care Excellence recommends involving the families of patients admitted to psychiatric hospital care, without specific guidance on how to do it. To improve family involvement in a National Health Service psychiatric intensive care unit, a relatives' and carers' clinic was set up. Fifty family members attended and completed questionnaires. Nine went on to take part in interviews, the results of which were analysed using thematic analysis.

Results

Families felt more informed and found the increased access to information useful. They felt that the process showed respect for them and their family member, and that their contribution was valued. Running throughout the interviews was the contrast with previous experiences; families reported feeling heard and understood and attributed this in part to timing and environment.

Clinical implications

The clinic was viewed positively by families and met the trust's commitment to including carers, as well as national guidance which suggests it should be part of routine practice.
Comparison of the oxidative potential of primary (POA) and secondary (SOA) organic aerosols derived from α-pinene and gasoline engine exhaust precursors
Authors: Lovett Christopher , Baasiri Mohamad , Atwi Khairallah , Sowlat Mohammad H. , Shirmohammadi Farimah , Shihadeh Alan L. , Sioutas Constantinos
Published: March 2019

Background: Primary (POA) and secondary (SOA) organic aerosols, deriving from both anthropogenic and biogenic sources, represent a major fraction of ambient particulate matter (PM) and play an important role in the etiology of respiratory and cardiovascular diseases, largely through systemic inflammation and cellular oxidative stress. The relative contributions of these species to the inhalation burden, however, are rather poorly characterized. In this study, we measured the in vitro oxidative stress response of alveolar macrophages exposed to primary and secondary PM derived from both anthropogenic and biogenic sources.

Methods: POA and SOA were generated within an oxidation flow reactor (OFR) fed by pure, aerosolized α-pinene or gasoline engine exhaust, as representative emissions of biogenic and anthropogenic sources, respectively. The OFR utilized an ultraviolet (UV) lamp to achieve an equivalent atmospheric aging process of several days.

Results: Anthropogenic SOA produced the greatest oxidative response (1900 ± 255 µg-Zymosan/mg-PM), followed by biogenic (α-pinene) SOA (1321 ± 542 µg-Zymosan/mg-PM), while anthropogenic POA produced the smallest response (51.4 ± 64.3 µg-Zymosan/mg-PM).

Conclusions: These findings emphasize the importance of monitoring and controlling anthropogenic emissions in the urban atmosphere, while also taking into consideration spatial and seasonal differences in SOA composition. Local concentrations of biogenic and anthropogenic species contributing to the oxidative potential of ambient PM may vary widely, depending on the given region and time of year, due to factors such as surrounding vegetation, proximity to urban areas, and hours of daylight.
Novel multiplex assay for profiling influenza antibodies in breast milk and serum of mother-infant pairs
Authors: Järvinen Kirsi M. , Wang Jiong , Seppo Antti E. , Zand Martin
Published: March 2019

Background: During early life, systemic protection to influenza is passively provided by transplacental transfer of IgG antibodies and oral and gastrointestinal mucosal protection via breast milk (BM) containing predominantly IgA. Immune imprinting, influenced by initial exposure of the infant immune system to influenza, has recently been recognized as an important determinant of future influenza immune responses.

Methods: We utilized stored frozen BM from a prospective birth cohort to assess immune factors in human milk. The earliest available BM and a paired, timed serum sample was assessed from each of  7 mothers. Paired infant serum samples were assayed at up to three time points during the first 12 months of life, one prior to assumed disappearance of transplacentally transferred IgG, and one after. We utilized a novel multiplex assay to assess mothers’ and infants’ IgG and IgA antibodies in serum to a panel of  30 individual recombinant hemagglutinin (rHA) proteins of influenza virus strains and chimeric rHAs. We also characterized IgA and IgG antibody levels in breast milk which provide mucosal protection.

Results: Our pilot results, analyzing a small number of samples demonstrate the feasibility of this method for studying paired maternal-infant IgG and IgA anti-influenza immunity patterns. Unlike IgG antibodies, breast milk influenza virus HA-specific IgA antibody levels and patterns were mostly discordant compared to serum.  As expected, there was a steady decay of infant influenza specific IgG levels by 6 to 8 months of age, which was not, however, comparable in all infants. In contrast, most of the infants showed an increase in IgA responses throughout the first year of life

Conclusions:  This new analytical method can be applied in a larger study to understand the impact of maternal imprinting on influenza immunity.

Patent ductus arteriosus and congestive heart failure in a cat
Authors: Sarcinella Fabio , Bode Elizabeth
Published: March 2019

This case report describes the clinical presentation, diagnosis and treatment of patent ductus arteriosus (PDA) in a 6-month-old cat, causing left-sided congestive heart failure. This congenital heart defect, rarely reported in the cat, was diagnosed during investigation of a loud, continuous heart murmur, exercise intolerance, tachypnoea and dyspnoea. The cat was started on medical treatment for congestive heart failure and underwent surgical closure of the PDA once optimal control of the heart failure had been achieved. The cat recovered well from the surgery, with no major complications and gradual resolution of the clinical signs. The cat was reported to be fully recovered following discontinuation of heart failure treatment 1 month after the surgery, and to be stable 4 months after surgery. This case report alerts the clinician to consider PDA within the list of differential diagnosis in a kitten with a continuous heart murmur, and demonstrates that surgical correction of this defect can be associated with an excellent prognosis.

Safe investigation of isolated change in bowel habit with a flexible sigmoidoscopy? A systematic review and meta-analysis
Authors: Herrod PJJ , Boyd-Carson H , Doleman B , Blackwell JEM , Hardy EJO , Harper F , Lund JN
Published: March 2019

Introduction

Public awareness campaigns have led to increasing referrals of patients to colorectal surgery for possible cancer. Change in bowel habit, is traditionally described as a symptom of a left sided bowel cancer. If this is the case in practice, it raises the potentially attractive option of investigating such patients with flexible sigmoidoscopy only. This study sought to systematically review the literature describing tumour location of patients with bowel cancer presenting with left-sided symptoms to establish the safety of potential investigation of these patients with flexible sigmoidoscopy alone.

Methods

A systematic review of studies reporting both the presenting symptoms of patients with bowel cancer and the location of their cancer in the bowel was prospectively registered (CRD42017072492). MEDLINE, EMBASE and CENTRAL were searched with no date or language restriction.

Results

Seven studies were included. Isolated change in bowel habit (with or without rectal bleeding) was a presenting symptom of 73% (95% CI 41–96%, I2 = 99%) of left-sided cancers but also in 13% (95% CI 2–30%, I2 = 96%) of right-sided cancers. In all patients with cancer who presented with isolated change in bowel habit (with or without rectal bleeding), the cancer was right sided in 8% (95% CI 4–12%, I2 = 69%).

Conclusions

There is a higher than expected risk that if a cancer is diagnosed in a patient presenting with either an isolated change in bowel habit or a combination of change in bowel habit with rectal bleeding, the cancer may be right sided.
Chronic osteomyelitis with proliferative periostitis of the mandibular body: report of a case and review of the literature
Authors: Liu D , Zhang J , Li T , Li C , Liu X , Zheng J , Su Z , Wang X
Published: March 2019

Chronic osteomyelitis with proliferative periostitis is a rare form of osteomyelitis that is characterised by new bone formation with periosteal reaction. It is also traditionally known as Garre’s osteomyelitis. The common sources of infection of the jaw include dental caries associated with periapical periodontitis, periodontitis, fractures and nonodontogenic infections. Chronic osteomyelitis with proliferative periostitis mainly presents in younger patients. Here, we present a case of a 12-year-old patient with chronic osteomyelitis with proliferative periostitis with no definitive infection source such as pericoronitis, caries and periodontitis. Therapeutic measures involved surgical debridement and antibiotics. Disease remission and a normal facial symmetrical morphology were observed at the six-month follow-up.

Acute ischaemic stroke is a devastating postoperative complication that significantly impacts upon a patient’s quality of life. Endovascular retrieval of thromboembolic material from proximal cerebral arteries by mechanical thrombectomy is the new standard of care for patients presenting with a proximal artery occlusion. We report the case of a patient developing an acute ischaemic stroke following pulmonary lobectomy, who was transferred to the regional neurosciences unit, despite the absence of an established referral pathway, to undergo mechanical thrombectomy, with significant prognostic neurological benefit. We would advocate all cardiothoracic centres identify their regional neurosciences unit and initiate discussion to establish a referral pathway.
Commutability of a Whole-Blood External Quality Assessment Material for Point-of-Care C-Reactive Protein, Glucose, and Hemoglobin Testing
Authors: Bukve Tone , Sandberg Sverre , Vie Wenche S , Sølvik Una , Christensen Nina G , Stavelin Anne
Published: March 2019

BACKGROUND

The optimal situation in external quality assessment (EQA) is to use commutable materials. No previous study has examined the commutability of a whole-blood material for point-of-care (POC) testing. The aim of this study was to determine the commutability of the Norwegian Quality Improvement of Laboratory Examinations (Noklus) organization's “in-house” whole-blood EQA material for C-reactive protein (CRP), glucose, and hemoglobin for frequently used POC instruments in Norway and to determine the possibility of using a common target value for each analyte.

METHODS

The study was performed according to the Clinical and Laboratory Standards Institute guidelines. The EQA material was pooled stabilized EDTA venous whole-blood containing different concentrations of the analytes. The EQA material and native routine patient samples were analyzed using 17 POC and 3 hospital instruments. The commutability was assessed using Deming regression analysis with 95% prediction intervals for each instrument comparison.

RESULTS

The EQA material was commutable for all CRP and hemoglobin POC instruments, whereas for glucose the material was commutable for all POC instruments at the lowest concentration analyzed [126.0 mg/dL (7.0 mmol/L)] and for 3 POC instruments at all of the concentrations analyzed.

CONCLUSIONS

Noklus EQA participants using CRP and hemoglobin POC instruments now receive results that are compared with a reference target value, whereas the results for participants using glucose POC instruments are still compared with method-specific target values. Systematic deviations from a reference target value for the commutable glucose POC instruments can be calculated, and this additional information can now be offered to these participants and to the manufacturers.

Authors: Kalangi Cherry G , Hariyanto Agus , Oley Mendy Hatibie
Published: March 2019

Background: Deep burn wound with exposed underlying structures such as muscle or moreover in this case, bone, may increase morbidity in the terms of infection. Therefore careful planning of reconstruction is needed.

Patient and Method: We report one case of neglected burn wound with exposed tibia and muscle contracture on bilateral knee joint that was reconstructed in our Plastic Surgery Division of Prof RD Kandou Hospital. Data was taken from medical and surgery record.

Result: We managed the muscle contracture of the left knee joint by sedated gradual stretching and splinting. We also utilized hyperbaric treatment in order to maximize granulation process. A medial gastrocnemius muscle flap followed by split thickness skin graft is used to reconstruct the missing tissue at upper tibia, and another split thickness skin graft to cover another wound at opposite upper leg. The result was satisfying without any complication.

Conclusion: In managing a neglected burn wound with bone exposed and muscle contracture, it is compulsory to have a careful reconstruction planning. Our objectives are to release the muscle contracture and to provide an adequate coverage to the bone-exposed wound by using many modalities we have.

Hand in Hand approach by culture and PCR a plausible solution for effective management of risks associated with Legionella in water samples
Authors: Bin Salem Samara , Jagadeesan Premanandh
Published: March 2019

Legionella in water distribution systems appear to be an unescapable threat to public health. The intensity of Legionellosis may vary from mild respiratory illness to potentially deadly pneumonia. Global incidences of Legionnaires disease outbreak has been raising over the years. Thus reliable analytical procedures play a crucial role in the evaluation of risk assessment and control of
Legionella. Analytical methods involving traditional culture method and PCR based rapid methods are currently being used in water quality monitoring. While each method has its own advantages and limitations of underestimating and overestimating the occurrence of
Legionella, we propose simultaneous application of culture and real time PCR for effective monitoring of
Legionella in water distribution systems.

Published: March 2019

Objective: Evaluate methylene blue (MB) formulations containing oxygen carrier at different pHs in antimicrobial photodynamic therapy (aPDT). Material and Methods: Biofilms of Pseudomonas aeruginosa PA01 formed over acrylics specimens during five days were treated with aPDT using different formulations: MB/pH 7.4; MB/pH 5.6; MB/carrier pH 7.4; MB/carrier pH 5.6. Biofilms not exposed to treatment were used as a control. Blind examiner for the experimental groups performed the counting of colonies per ml suspension (CFU/ml). Two-way ANOVA was used to determine the effect of factors solvent (carrier vs water) and pH (7.4 vs 5.6). One-way ANOVA and post-hoc Tukey’s test was used to evaluate differences among the five groups (control; MB/carrier pH 7.4; MB pH 7.4; MB/carrier pH 5.6; MB pH 5.6). The Statistics 8.0 software was used (P<0.05). Results: All of photodynamic therapy groups showed significant reduction in P. aeruginosa compared to the control group. The solvent factor was not significant (P=0.18), while the pH factor presented statistical significance (P=0.01). When the carrier was used, MB formulation at pH 7.4 presented a statistically greater reduction of P. aeruginosa than the formulation with pH 5.6. Conclusion: The PDT using methylene blue formulations with oxygen carrier demonstrated potential for the treatment of localized infections by P. aeruginosa. MB formulations with oxygen carrier and pH 7.4 resulted in higher antimicrobial effect and should be considered for future studies with multispecies biofilms.  KeywordsAntimicrobial photodynamic therapy; biofilm; laser; Pseudomonas aeruginosa.

Published: March 2019

Objective: Erosive challenges are capable of demineralizing dentin and promote physical and mechanical changes in restorative materials. The present study investigates the water sorption and solubility of one nanofilled resin composite submitted to erosive challenges. It also studies procedures that can protect these surfaces. Materials and methods: 120 specimens were used. It was divided into four experimental groups according to the type of surface protection used (negative control, topical application of fluoride, resin-modified glass ionomer varnish and resin-based sealant). Subsequently, they were randomly assigned to three subgroups (n = 10), (negative control, 9 and 18 cycles of DES-RE). According to the exposure to the simulated solution of gastric acid (DES) (5% HCl, pH = 2.2) and subsequent remineralization (RE). The specimens were dehydrated until a constant mass was obtained and immersed in distilled water for 7 days, when they were weighed and submitted to a new dehydration. The values of water sorption and solubility were calculated according to the ISO 4049: 2000 specifications and analyzed statistically (2-way ANOVA / Tukey, alpha = 5%). Results: The water sorption and solubility averages after 18 cycles of DES-RE were statistically higher than negative control. Independently of the erosive challenge received, the specimens protected with the resin-modified glass ionomer varnish presented a significant increase in the values of loss and mass gain in relation to the other groups. Conclusion: No control method presented promising surface protection capacity of composite resin against to erosive challenges.KeywordTooth erosion; Dental restoration permanent; Solubility.
Use of Cone Beam Computed Tomography to Identify the Morphology of Maxillary and Mandibular Premolars in Chennai Population
Authors: Rajakeerthi Rajamohan , Nivedhitha Malli Suresh Babu
Published: March 2019

Objective: The complex root canal anatomy is inherently colonised by microbial flora. Endodontic treatment success is always related to adequate disinfection of the root canal space, which ultimately affects the treatment outcome. A thorough understanding of the external and internal root canal anatomy by using adequately imaging modalities is essential before planning any treatment. The aim of this study was to investigate the number and morphology of the root canals of maxillary and mandibular premolars in Chennai population. Material and Methods: Full-size cone-beam computed tomographic images were randomly collected from 100 patients, resulting in a total of 200 first and 200 second maxillary premolars as well as 200 first and 200 second mandibular premolars. All the eight premolars were analysed in single patients, who underwent cone-beam computed tomography scanning during pre-operative assessment (before implant surgery, orthodontic treatment, diagnosis of dental-alveolar trauma or difficult root canal treatment). Total number of roots and root canals, frequency and correlations between men and women were recorded and statistically analysed by using chi-square tests. The root canal configurations were rated according to the Vertucci’s classification. Results: In the maxillary first premolar group (n = 200), 36.3% had 1 root, 56.7% had 2 roots and 7.0% had 3 roots, with most exhibiting a type IV canal configuration. In the maxillary second premolar group (n = 200), 60% had 1 root, 29.8% had 2 roots and 10.2% had 3 roots, with the majority of single-rooted second premolars exhibiting a type I canal configuration. In the mandibular first premolar group (n = 200), 80.5% had 1 root, 9.8% had 2 roots and 5% had 3 roots. In the mandibular second premolar group (n=200), 90.1% had 1 root, 6.4% had 2 roots and 3.5 % had 3 roots, with most exhibiting a type I canal configuration. No statistical correlation was found between number of roots, gender and tooth position. Conclusion: This cone-beam computed tomographic study confirmed previous anatomical and morphological investigations. Therefore, the possibility of additional root canals should be considered when treating premolars. Keywords: Cone-beam computed tomography; Mandibular; Maxillary; Premolar; Root canal; Morphology.

La presencia de elementos naturales y su valoración en la literatura y las representaciones plásticas (relieves, pintura vascular) no es abundante en un ámbito, el de la Grecia de la antigüedad, en el que la figura humana y la antropomorfización se configuraron como regla fundamental. Sin embargo, a pesar de la relativa escasez de motivos naturales, su significación en el marco de la imaginación mítica helena es relevante, y no solamente como motivo subyacente o complementario. En este trabajo intentaremos revelar, a través del comentario de fuentes textuales y el análisis de algunas representaciones, sobre todo vasculares, la especial interdependencia entre el ser humano y el medioambiente, así como el valor mítico-simbólico de paisajes naturales, agrestes o cultivados, además de los elementos propios del mismo, como el agua, la vegetación, sobre todo árboles, o accidentes del relieve, como las montañas.

Clube da Esquina versus Tropicalismo: conflitos simbólicos na MPB
Authors: Diniz Sheyla Castro
Published: March 2019

Em 2018, o antológico álbum Clube da Esquina completou 46 anos. Seus autores, Milton Nascimento e Lô Borges, não imaginavam que o disco duplo lançado pela EMI-Odeon em 1972 se tornaria nome de um movimento musical, tal como a crítica jornalística e parte da crítica acadêmica trataram de assim legitimar a ampla turma de compositores, músicos e amigos reunida em torno de Milton. Uma das mais criativas e versáteis “formações culturais” atuantes na década de 1970, o Clube da Esquina ocupa hoje um lugar de destaque na MPB – para não falar do já conquistado prestígio internacional. Em meio aos processos que conduziram ao seu reconhecimento, um assunto geralmente ignorado pela bibliografia consistiu no fato de que o Tropicalismo foi vetor de alguns conflitos simbólicos que, neste artigo, busco trazer à tona e problematizar.

Versão portuguesa do Cyber Dating Abuse Questionaire (CDAQ) – Questionário sobre Ciberabuso no Namoro (CibAN): Adaptação e propriedades psicométricas
Authors: Caridade Sónia Maria , Braga Teresa
Published: March 2019

Algumas manifestações de violência no namoro ocorrem através do uso das novas tecnologias, pelo que importa investigar esta tipologia de abuso apelidada internacionalmente de cyber dating abuse. O presente estudo procurou traduzir e adaptar, para a população portuguesa, o Cyber Dating Abuse Questionaire (CDAQ; Borrajo, Gámez-Guadix, Pereda, & Calvete, 2015), estudando as suas propriedades psicométricas. A versão portuguesa foi administrada a uma amostra de 272 estudantes, a grande maioria (87%) de sexo feminino e com uma média de idades de 28.41 (DP=7.02). A análise fatorial confirmatória revelou bons índices de ajustamento, permitindo confirmar o modelo fatorial do instrumento original constituído por quatro fatores correlacionados, dois relativos à vitimação por agressão direta e controlo e dois à perpetração dessas mesmas tipologias de violência. Adicionalmente, todos os fatores revelaram boa consistência interna. Ainda que os indicadores de prevalência de vitimação e perpetração por controlo (58.8% vs. 63.2%, respetivamente) se tenham revelado mais preponderantes comparativamente aos de vitimação e perpetração por agressão direta (18% vs. 14.7%), foi possível confirmar que estes dois tipos de ciberabuso íntimo constituem comportamentos entre os jovens portugueses estudantes universitários envolvidos/as em relações íntimas. As implicações práticas e empíricas futuras deste estudo são objeto de discussão neste trabalho.

Tendo em conta o interesse recente nas intervenções baseadas na aceitação para a psicose, tem sido recomendado que os mecanismos de coping com as vozes, nomeadamente a aceitação experiencial, sejam avaliados no contexto clínico e de investigação. A Escala de Aceitação e Ação em relação às Vozes (VAAS-12) é um instrumento de autorresposta especificamente desenvolvido para avaliar as crenças baseadas na aceitação ou na ação em relação às alucinações auditivo-verbais. O presente estudo tem como objetivo a tradução, adaptação e estudo das propriedades psicométricas da versão portuguesa da VAAS-12 numa amostra clínica dentro do espectro das perturbações psicóticas. A VAAS-12 foi traduzida e adaptada para Português. As suas propriedades psicométricas foram posteriormente estudadas numa amostra de cinquenta e quatro participantes do sexo masculino, maioritariamente solteiros, desempregados e com uma experiência de ouvir vozes na última semana. Foram realizadas análises fatoriais confirmatórias para as estruturas de um e dois fatores sugeridas em estudos prévios, sendo que ambas apresentaram índices de ajustamento inaceitáveis. A análise fatorial exploratória realizada posteriormente revelou uma estrutura alternativa de dois fatores (“Não interferência e ação” e “Aceitação e Funcionamento”) que obteve ajustamento adequado. Foi encontrada adequada consistência interna e validade de constructo, tendo sido encontradas associações negativas com a perceção das vozes como hostis-dominantes e resistência em relação às vozes. A VAAS-12 parece ser adequada para uso em contexto clínico e de investigação, embora mais estudos sejam necessários particularmente no que diz respeito à subescala “Aceitação e Funcionamento”.
Associações entre o uso do script de base segura e o conhecimento das emoções em crianças de idade pré-escolar

As associações entre a segurança da vinculação e múltiplos aspetos do desenvolvimento emocional têm sido estudadas durante várias décadas. Embora estes estudos sejam válidos, algumas respostas relacionadas com as representações de vinculação e o conhecimento emocional continuam em aberto. Participaram neste estudo crianças de idade pré-escolar (N=40). Utilizámos o Attachment Story Completion Task como medida de vinculação das crianças, com as representações a serem avaliadas enquanto acesso e uso do script de base segura (SBS) para organizar as narrativas de vinculação das crianças. O conhecimento emocional foi avaliado com recurso ao Teste do Conhecimento das Emoções. O nosso principal objetivo era demonstrar que o SBS se comporta como uma típica medida das representações de vinculação, no que diz respeito à sua associação com a compreensão das emoções por parte das crianças. Os resultados sugerem que as crianças com histórias de vinculação segura tendem a ter uma maior base de conhecimento emocional. A medida de SBS comportou-se de forma semelhante a outras medidas de segurança de vinculação, sugerindo a sua validade enquanto medida de representações de vinculação durante a infância.
A contemporary vision of project success criteria
Authors: Castro Marcela Souto , Bahli Bouchaib , Farias Filho José Rodrigues , Barcaui Andre
Published: March 2019

Goal: The objective of this research is to provide researchers and project management professionals with a contemporary view of the measurement of project success.

Design/Methodology/Approach: After a dense literature review, a research-based study analyzes the project success criteria perspectives of 264 Brazilian project managers and provides a ranking of the most widely used measures in practice in Brazilian organizations.

Results: The study analyzes contemporary literature on project success criteria and discusses overlaps and trends. One of the important findings of this research is the identification of mismatches between academic perspectives and those of project managers in regard to project success as well as real success criteria used in organizations.

Limitations of the investigation: As the sample covered was comprised exclusively of Brazilian project managers, cross-cultural success criteria research is, therefore, encouraged.

Practical implications: The proposed performance criteria can be used in future research and for professional proposes in success criteria assessment.

Originality/Value: Given the diversity of success criteria measures, authors can have difficulty in finding the one that better fits their needs; alternatively, they can create their own scale. The reliability of several studies can be questioned due to their subjectivity and, in some cases, weakly defined measures. The present study can therefore provide project professionals with guidelines for success assessment that make measuring and comparing different projects possible.

Insurance-markets Equilibrium with Sequential Non-convex Straight-time and Over-time Labor Supply
Authors: VASILEV Aleksander
Published: March 2019

This note describes the lottery - and insurance-market equilibrium in an economy with non-convex straight-time and overtime employment. In contrast to Hansen and Sargent (1988), the overtime-decision is a sequential one. This requires two separate insurance market to operate, one for straight-time work, and one for overtime. In addition, given that the labor choice for regular and overtime hours is made in succession, the insurance market for overtime needs to open once the insurance market has closed. This segmentation and sequentiality of insurance markets operation is a new result in the literature and a direct consequence of the sequential nature of the overtime labor decision.
Critical notes about Noether's theorem (Part I)
Authors: CARFI’ David
Published: March 2019

In this brief critical notes, we state and prove the classic Noether's theorem, in a language and in the mood of modern Differential Geometry. This modern approach, on one hand, wants to stimulate a dialogue between the classic Noether's theorem version users and the modern differential geometry developers, on the other hand, it opens the way for some extensions of the theorem, with possible physical insights about the matter.
