Informetrics on M. N. Srinivas
No full textM. N. Srinivas, the well known sociologist is widely recognised as architect of modern Indian sociology and social anthropology. His publications have been analysed by year, domain, authorship pattern, channels of communication used. Keywords, etc. The results indicate that the papers published by him are of a nature that qualify him to be a 'role model' for the younger generations to emulate.
By the end of 1995, Srinivas had to his credit 144 papers which, included 33 broad papers in sociology and anthropology; 18 papers in social change; 28 papers in village studies; 12 papers on religion; 17 papers on caste and 36 papers of general popular interest. The periods 1958-61 and 1974-77, when Srinivas was 38-41 and 58-61 years old. were his most productive periods with highest publication activity
Ordenamiento del Desarrollo Tur?stico del cant?n Zamora Provincia de Zamora Chinchipe
No full textLa adecuada planificaci?n del uso del espacio f?sico en los destinos es un factor clave para prevenir conflictos de uso entre los actores involucrados en el desarrollo de las actividades tur?sticas y recreativas; m?s a?n, cuando de por medio existen recursos naturales y culturales que merecen especial atenci?n, cuidado y potencializaci?n. Este trabajo investigativo examina las potencialidades tur?sticas del cant?n Zamora. Con la participaci?n de actores locales se identifican tres zonas tur?sticas, se proponen cinco programas y quince proyectos que aportar?n al desarrollo tur?stico sostenible del cant?n Zamora. Esta propuesta se basa en la acci?n participativa y articula a todos los actores con una visi?n de desarrollo integral. Por otra parte, los resultados muestran la factibilidad de implementar dos nuevas rutas tur?sticas basadas en las caracter?sticas y potencialidades existentes en dos de las tres zonas identificadas, de tal modo que se dinamice la oferta tur?stica del cant?n. En tal virtud, la propuesta ?Ordenamiento del desarrollo tur?stico del cant?n Zamora?, es una herramienta de apoyo para el desarrollo tur?stico sostenible del sector y contribuye al desarrollo integral de la poblaci?n.Mag?ster en Planificaci?n Tur?stic

Variants of spectral Tur\'an theorems and eigenvectors of graphs
No full textIn 2002, Nikiforov proved that for an -vertex graph with clique number
and edge number , the spectral radius satisfies
, which confirmed a conjecture
implicitly suggested by Edwards and Elphick. In this paper, we prove a local
version of spectral Tur\'an inequality, which states that , where is the order of the largest
clique containing the edge in . We also characterize the extremal
graphs. We prove that our theorem implies Nikiforov's theorem and give an
example to show that the difference of Nikiforov's bound and ours is for some cases. Additionally, we establish a spectral counterpart
to Ore's problem (1962) which asks for the maximum size of an -vertex graph
such that its complement is connected and does not contain as a subgraph.
Our result leads to a new spectral Tur\'an inequality applicable to graphs with
connected complements. Finally, we disprove a conjecture of Gregory, asserting
that for a connected -vertex graph with chromatic number and
an independent set , we have where is the component of
the Perron vector of with respect to the vertex . A modified version of
Gregory's conjecture is proposed.Comment: 20 pages. This is a new version of the previous paper titled "A local
version of spectral Tur\'an theorem". In this version, we add more results,
including a variant of spectral Tur\'an theorem and a disproof of a
conjecture of Gregor
THE IMPACT OF RE-TUR ON CLINICAL OUTCOMES IN A LARGE COHORT OF T1G3 PATIENTS TREATED WITH BCG.
No full textScopo del lavoro
Re-TUR is strongly advocated for T1G3, because of the high incidence residual disease and mainly the risk
of substaging. Its real clinical value remains to be determined and the clinical factors that may influence
the decision. Some authors suggest that when muscle is present in the specimen, re-TUR may be avoided.
To evaluate if the presence of muscle or not at the first TUR in T1G3 bladder cancer makes a difference in
recurrence, progression and cancer specific survival after re-TUR.
Materiali e metodi
In a large retrospective cohort of 2530 primary T1G3 initially treated with BCG, 953 (37.7%) had a re-TUR.
According to the presence or not of muscle in the specimen of primary TUR, patients were divided in 4
groups: group 1 (no muscle, no re-TUR), group 2 (no muscle, re-TUR), group 3 (muscle, no re-TUR) and
group 4 (muscle, re-TUR). Clinical outcomes were compared across the 4 groups.
Risultati
Table 1 shows the distribution of prognostic factors and clinical outcomes across the 4 groups. Large
tumours and multifocal tumours were more likely to have received a re-TUR independent of whether or not
the primary specimen contained muscle. Re-TUR had a significant impact on progression, cancer specific
(CSS) and overall survival (OS) only when muscle was not present in the primary specimen. When adjusting
for the most important prognostic factors including age, tumour size and the presence of CIS, re-TUR in the
absence of muscle maintained a positive impact on time to progression (HR 0.44, p=0.048), CSS (HR 0.31;
p=0.067), and OS (HR 0.50; p=0.060) and showed a borderline effect on time to first recurrence (HR 0.69;
p=0.100). Re-TUR in presence of muscle in the primary specimen did not improve the outcome for any of
the endpoints after adjusting for prognostic factors.
Discussione
Even if re TUR is recommended in high risk tumors, it can delay the intravescial therapy. When muscle is
present in TUR specimen the risk of substaging or residual tumor should be balanced with the need of keep
on with adequate treatments.
Conclusioni
Our retrospective analysis shows that re-TUR may not be mandatory in T1G3 patients when muscle is
present in the specimen of the primary TUR

Combinatorial batch codes
No full textIn this paper, we study batch codes, which were introduced by Ishai, Kushilevitz, Ostrovsky and Sahai in [4]. A batch code specifies a method to distribute a database of [n] items among [m] devices (servers) in such a way that any [k] items can be retrieved by reading at most [t] items from each of the servers. It is of interest to devise batch codes that minimize the total storage, denoted by [N] , over all [m] servers.
We restrict out attention to batch codes in which every server stores a subset of the items. This is purely a combinatorial problem, so we call this kind of batch code a ''combinatorial batch code''. We only study the special case [t=1] , where, for various parameter situations, we are able to present batch codes that are optimal with respect to the storage requirement, [N] . We also study uniform codes, where every item is stored in precisely [c] of the [m] servers (such a code is said to have rate [1/c] ). Interesting new results are presented in the cases [c = 2, k-2] and [k-1] . In addition, we obtain improved existence results for arbitrary fixed [c] using the probabilistic method
