Gaugino Anomaly Mediated SUSY Breaking: phenomenology and prospects for the LHC

We examine the supersymmetry phenomenology of a novel scenario of supersymmetry (SUSY) breaking which we call Gaugino Anomaly Mediation, or inoAMSB. This is suggested by recent work on the phenomenology of flux compactified type IIB string theory. The essential features of this scenario are that the gaugino masses are of the anomaly-mediated SUSY breaking (AMSB) form, while scalar and trilinear soft SUSY breaking terms are highly suppressed. Renormalization group effects yield an allowable sparticle mass spectrum, while at the same time avoiding charged LSPs; the latter are common in models with negligible soft scalar masses, such as no-scale or gaugino mediation models. Since scalar and trilinear soft terms are highly suppressed, the SUSY induced flavor and CP-violating processes are also suppressed. The lightest SUSY particle is the neutral wino, while the heaviest is the gluino. In this model, there should be a strong multi-jet +etmiss signal from squark pair production at the LHC. We find a 100 fb^{-1} reach of LHC out to m_{3/2}\sim 118 TeV, corresponding to a gluino mass of \sim 2.6 TeV. A double mass edge from the opposite-sign/same flavor dilepton invariant mass distribution should be visible at LHC; this, along with the presence of short-- but visible-- highly ionizing tracks from quasi-stable charginos, should provide a smoking gun signature for inoAMSB.Comment: 30 pages including 14 .eps figure

Designing Privacy for You : A User Centric Approach For Privacy

Privacy directly concerns the user as the data owner (data- subject) and hence privacy in systems should be implemented in a manner which concerns the user (user-centered). There are many concepts and guidelines that support development of privacy and embedding privacy into systems. However, none of them approaches privacy in a user- centered manner. Through this research we propose a framework that would enable developers and designers to grasp privacy in a user-centered manner and implement it along with the software development life cycle.Comment: 14 pages, HCI International 2017 Vancouver, Canad

Testing the gaugino AMSB model at the Tevatron via slepton pair production

Gaugino AMSB models-- wherein scalar and trilinear soft SUSY breaking terms are suppressed at the GUT scale while gaugino masses adopt the AMSB form-- yield a characteristic SUSY particle mass spectrum with light sleptons along with a nearly degenerate wino-like lightest neutralino and quasi-stable chargino. The left- sleptons and sneutrinos can be pair produced at sufficiently high rates to yield observable signals at the Fermilab Tevatron. We calculate the rate for isolated single and dilepton plus missing energy signals, along with the presence of one or two highly ionizing chargino tracks. We find that Tevatron experiments should be able to probe gravitino masses into the ~55 TeV range for inoAMSB models, which corresponds to a reach in gluino mass of over 1100 GeV.Comment: 14 pages including 6 .eps figure

Measures of satisfaction with care during labour and birth: a comparative review

Background Satisfaction is the one of the most frequently reported outcome measures for quality of care. Assessment of satisfaction with maternity services is crucial, and psychometrically sound measures are needed if this is to inform health practices. This paper comparatively reviews current measures of satisfaction with care during labour and birth. Methods A review of the literature was conducted. Studies were located through computerised databases and hand searching references of identified articles and reviews. Inclusion criteria were that the questionnaire was a multi-item scale of satisfaction with care during labour and birth, and some form of psychometric information (either information about questionnaire construction, or reliability, or validity) had to be reported. Results Nine questionnaires of satisfaction with care during labour and birth were identified. Instruments varied in psychometric properties and dimensions. Most described questionnaire construction and tested some form of reliability and validity. Measures were generally not based on the main theoretical models of satisfaction and varied in scope and application to different types of samples (e.g. satisfaction following caesarean section). For an in-depth measure of satisfaction with intrapartum care, the Intrapartal-Specific Quality from the Patient’s Perspective questionnaire (QPP-I) is recommended. Brief measures with good reliability and validity are provided by the Six Simple Questions (SSQ) or Perceptions of Care Adjective Checklist (PCACL-R). Conclusions Despite the interest in measures of satisfaction there are only a small number of validated measures of satisfaction with care during labour and birth. It is important that brief, reliable and valid measures are available for use in general and specific populations in order to assist research and inform practice

Impact of internal governance on creating entrepreneurial universities: a study based on Sri Lankan universities

Becoming an entrepreneurial university is the key strategy that needs to be adopted by public universities at present. When becoming an entrepreneurial university they need to adopt innovative and entrepreneurial approaches in the provision of their products and services and develop partnerships, networks and other relationships with public and private organizations. To adopt for all these internal governance structure (university structure and leadership) of the public universities plays a key role. This research intends to identify how far Sri Lankan public universities organizational structure and entrepreneurial leadership behavior has supported on becoming entrepreneurial universities. The study has developed two hypothesis and primary data collected from four public universities has been analyzed through regression analysis. Finally, outcomes of this research identified that university structure has a significant negative impact in the process of becoming an entrepreneurial university as well as entrepreneurial leadership behavior is still lacking from Sri Lankan context

Shrimp waste management Use of dried papaya milk in chitosan manufacture

Chitin is the second most abundant carbon biopolymer on earth, next to cellulose. It is the majorconstituent in the exo-skeleton of crustacean water animals such as shrimps, crabs etc. Shrimp wasteis a major cause for environmental pollution in shrimp cultivating areas such as Puttalam. Currentannual shrimp production in Sri Lanka is about 4000 MT and the shrimp waste produced is about1200 MT. This shrimp waste at present is discharged into environment or buried without any treatment,thereby causing serious environmental pollution problems.Chitosan, which can be obtained from chitin by chemical treatment, is a polysaccharide of very higheconorn ic importance with a wide range of industrial applications. If Sri Lanka can convert its shrimpwaste in to chitosan, it can be a major foreign exchange earner, in addition to solving the problem ofenvironmental pollution caused by shrimp waste.A method for the production of chitosan from shrimp waste using dried papaya milk (OPM) has beendeveloped (Sri Lanka Patent No 13544,2005). It involves the treatment of demineralised (with 4%HCI) shrimp waste with OPM followed by deproteinization with 3% NaOH and deacetylation with50% NaOH. The use ofOPM brings about a 25% reduction in the amount ofNaOH, which is knownto cause environmental pollution problems. Typically, the degree of deacetylation (~O) of resultingchitosan was 66% comparable to DO of conventional methods. Moisture content (11.2%) and ashcontent (0.69%) of resulting chitosan were also comparable to those obtained by 100% chemicalmethods.

Barriers and facilitators to the uptake of electronic collection and use of patient-reported measures in routine care of older adults:a systematic review with qualitative evidence synthesis

Objective: The aims of this systematic review were to (1) synthesize the available qualitative evidence on the barriers and facilitators influencing implementation of the electronic collection and use of patient-reported measures (PRMs) in older adults' care from various stakeholder perspectives and (2) map these factors to the digital technology implementation framework Non-adoption, Abandonment, challenges to the Scale-up, Spread, Sustainability (NASSS) and behavior change framework Capability, Opportunity, Motivation, Behaviour (COM-B). Materials and Methods: A search of MEDLINE, CINAHL Plus, and Web of Science databases from 1 January 2001 to 27 October 2021 was conducted and included English language qualitative studies exploring stakeholder perspectives on the electronic collection and use of PRMs in older adults' care. Two authors independently screened studies, conducted data extraction, quality appraisal using the Critical Appraisal Skills Programme (CASP), data coding, assessed confidence in review findings using Grading of Recommendations Assessment, Development, and Evaluation Confidence in the Evidence from Reviews of Qualitative Research (GRADE CERQual), and mapped the findings to NASSS and COMB. An inductive approach was used to synthesize findings describing the stakeholder perspectives of barriers and facilitators. Results: Twenty-two studies were included from the 3368 records identified. Studies explored older adult, caregiver, healthcare professional, and administrative staff perspectives. Twenty nine of 34 review findings (85%) were graded as having high or moderate confidence. Key factors salient to older adults related to clinical conditions and socio-cultural factors, digital literacy, access to digital technology, and user interface. Factors salient to healthcare professionals related to resource availability to collect and use PRMs, and value of PRMs collection and use. Conclusion: Future efforts to implement electronic collection and use of PRMs in older adults' care should consider addressing the barriers, facilitators, and key theoretical domains identified in this review. Older adults are more likely to adopt electronic completion of PRMs when barriers associated with digital technology access, digital literacy, and user interface are addressed. Future research should explore the perspectives of other stakeholders, including those of organizational leaders, digital technology developers and implementation specialists, in various healthcare settings and explore factors influencing implementation of PREMs.</p

EFFECT OF THE PERIOD OF THE YEAR WHICH EXPLANTS WERE COLLECTED ON SHOOT GROWTH AND THE CALLUS FORMATION OF THE TISSUE CULTURED JACK FRUIT

A method for rapid propagation of mature Jack fruit from apical meristem culture wasdeveloped. Apical meristems were estahlished in Modified Campbell and Durzan mediumsupplemented with NAA and ISA. Cultures were suh cultured in every 4 weeks interval inorder to reduce the accumulation of phenolic compounds. Reducing the accumulatedphenolics at the base of the explant enhanced the growth rate. There was a significantdifference in the growth performance of shoots and callus produced according to the periodof the year in which explants were collected.60% of the apical meristems cultured in modified CD medium supplemented with IBA andNAA produced shoots in November to December period. It was only 30% when the apiceswere cultured in April to May months and decreased to 20% in June - July months. Theshoots produced in November - December period showed a higher vigour (in number ofleaves per shoot. mean leaf width and mean shoot length) than those produced in othermonths. Since jackfruit show seasonal changes in fruit bearing and shedding of leaves. itcan be suggested that the difference in growth performances of tissues cultured in artificialculture media would have been effected by endogenous rhythms. It has been observed thatthe callus production depends on the incubation temperature. Callus was induced at thebase of the shoot hy increasing the incubation temperature from 2S± IIIC to 30± Ifie.Growth of the callus was also retarded hy accumulated phenolic compounds in themedium.
