Management of Early Glottic Cancer Treated by CO2 Laser According to Surgical-Margin Status: A Systematic Review of the Literature
2021
Abstract Introduction Transoral laser microsurgery (TLM) is the treatment of choice for Tis-T2 squamous cell glottic carcinomas due to its advantages compared with open surgery and radiotherapy. However, the CO2 laser beam causes changes and damage on the specimens, making the histological assessment of resection margins, the gold standard for confirming radical tumor resection, sometimes difficult. Objective To assess the different ways to manage patients depending on the status of the histopathological margin according to recent studies to detect the most commonly shared therapeutic strategy. Data Synthesis We analyzed the literature available on the PubMed and Web of Science databases, i…
Spin Crossover and Long-Lived Excited States in a Reduced Molecular Ruby.
2020
Abstract The chromium(III) complex [CrIII(ddpd)2]3+ (molecular ruby; ddpd=N,N′‐dimethyl‐N,N′‐dipyridine‐2‐yl‐pyridine‐2,6‐diamine) is reduced to the genuine chromium(II) complex [CrII(ddpd)2]2+ with d4 electron configuration. This reduced molecular ruby represents one of the very few chromium(II) complexes showing spin crossover (SCO). The reversible SCO is gradual with T 1/2 around room temperature. The low‐spin and high‐spin chromium(II) isomers exhibit distinct spectroscopic and structural properties (UV/Vis/NIR, IR, EPR spectroscopies, single‐crystal XRD). Excitation of [CrII(ddpd)2]2+ with UV light at 20 and 290 K generates electronically excited states with microsecond lifetimes. This…
¿Cómo motivar al alumnado de la eso a través del área de música? La formación corporal como recurso didáctico
2018
espanolSe presenta una propuesta didactica que pretende ofrecer, al alumnado de ensenanza secundaria obligatoria, una educacion y una formacion corporal basicas, a traves del area de musica. La finalidad es realizar una investigacion que nos permita conocer si, a partir del area de musica, se puede favorecer la actitud, el interes y la motivacion de los alumnos de este nivel educativo por esta asignatura, contribuyendo al mismo tiempo a su desarrollo integral. Esta propuesta, tambien permite ofrecer a los alumnos de la ESO la oportunidad de aprender y experimentar con tecnicas especificas. catalaEs presenta una proposta didactica que preten oferir, a l’alumnat d’ensenyament secundari obliga…
”Mitä pitäisi kehittää ja miten?” : lukiolaisten kokemuksia arvioinnista ja sen menetelmistä englannin opinnoissa
2020
Opiskelija-arvioinnilla on merkittävä asema kaikkialla koulumaailmassa, niin myös suomalaisessa lukiossa. Vaikutusvaltaisesta roolistaan huolimatta arviointia ja sen käytännön toteutusta lukiossa tai lukion kieltenopetuksessa on tutkittu niukasti. Tämän tutkimuksen tavoitteena oli tutkia kyselylomakkeen avulla, kuinka lukiolaiset (146 lukiolaista yhdestä koulusta) itse kokivat arvioinnin osana englannin opintojaan, millaisia arviointimenetelmiä he olivat kohdanneet ja mitä niistä he pitivät hyödyllisinä. Tämän tutkimuksen perusteella opiskelijat arvostivat arviointia, jonka he kokivat osuvan varsin oikeaan ja olleen melko monipuolista. Arviointi ei kuitenkaan ohjannut heitä eteenpäin kovink…
The power of assessment: What (dis)empowers students in their EFL assessment in a Finnish upper secondary school?
2017
Assessment wields a great deal of power over students. Yet, there is little research on how students, either in general or as individuals, experience assessment. Therefore, this study aimed to explore what disempowers or empowers students in EFL assessment. A total of 146 students from one Finnish upper secondary school answered a questionnaire on assessment and feedback in their EFL studies. The study utilises mixed methods: primarily, the questionnaire data was analysed quantitatively (principal component analysis, step-wise regression analysis), secondarily, qualitative data and analysis were also used. The analyses showed that students reacted to assessment in highly individual ways. Wh…
Enabling and constraining family: young women building their educational paths in Tanzania
2015
For an increasing number of African girls and women, upgrading the level of education has become a strategy for life improvement. This paper analyses the role that family plays in enabling women's education and contributes to understanding on the interconnectivity of education, work and family in women's lives in collective societies. The analysis focuses on how young Tanzanian women perceive the role of family and education in their ‘youth task’, of becoming adult. The analysis is based on interviews with seven young Tanzanian women enrolled in non-formal secondary education and nine professional women enrolled in higher education. The results show that the women were determined to pursue …
The Radó–Kneser–Choquet theorem for $p$-harmonic mappings between Riemannian surfaces
2020
In the planar setting the Rad\'o-Kneser-Choquet theorem states that a harmonic map from the unit disk onto a Jordan domain bounded by a convex curve is a diffeomorphism provided that the boundary mapping is a homeomorphism. We prove the injectivity criterion of Rad\'o-Kneser-Choquet for $p$-harmonic mappings between Riemannian surfaces. In our proof of the injecticity criterion we approximate the $p$-harmonic map with auxiliary mappings that solve uniformly elliptic systems. We prove that each auxiliary mapping has a positive Jacobian by a homotopy argument. We keep the maps injective all the way through the homotopy with the help of the minimum principle for a certain subharmonic expressio…
On arithmetic sums of Ahlfors-regular sets
2021
Let $A,B \subset \mathbb{R}$ be closed Ahlfors-regular sets with dimensions $\dim_{\mathrm{H}} A =: \alpha$ and $\dim_{\mathrm{H}} B =: \beta$. I prove that $$\dim_{\mathrm{H}} [A + \theta B] \geq \alpha + \beta \cdot \tfrac{1 - \alpha}{2 - \alpha}$$ for all $\theta \in \mathbb{R} \, \setminus \, E$, where $\dim_{\mathrm{H}} E = 0$.

Governing at the frontier of the European Commission : the case of seconded national officials
2005
Studies of executive institutions have largely dealt separately with national and international executive institutions (IEIs). This study unpacks and repacks four conflicting decision-making dynamics that unfolds at the frontier of IEIs – that is, at the institutional rim where national and international executive institutions meet, interact and collide. The empirical laboratory utilised is seconded national experts in the European Commission. The survey and interview data presented demonstrates that the decision-making behaviour of seconded national experts includes a mix of departmental (portfolio), epistemic (expert) and supranational behaviour. The suspicion early voiced by Coombes (197…
