Clinical review: Can we predict which patients are at risk of complications following surgery?

There are a vast number of operations carried out every year, with a small proportion of patients being at highest risk of mortality and morbidity. There has been considerable work to try and identify these high-risk patients. In this paper, we look in detail at the commonly used perioperative risk prediction models. Finally, we will be looking at the evolution and evidence for functional assessment and the National Surgical Quality Improvement Program (in the USA), both topical and exciting areas of perioperative prediction

Energy Efficient Sleep Awake Aware (EESAA) Intelligent Sensor Network Routing Protocol

Wireless Sensor Networks (WSNs), with growing applications in the environment which are not within human reach have been addressed tremendously in the recent past. For optimized working of network many routing algorithms have been proposed, mainly focusing energy efficiency, network lifetime, clustering processes. Considering homogeneity of network, we proposed Energy Efficient Sleep Awake Aware (EESAA) intelligent routing protocol for WSNs. In our proposed technique we evaluate and enhance certain issues like network stability, network lifetime and cluster head selection process. Utilizing the concept of characteristical pairing among sensor nodes energy utilization is optimized. Simulation results show that our proposed protocolnificantly improved theComment: 15th IEEE International Multi Topic Conference (INMIC12), 201

Stop Co-Annihilation in the Minimal Supersymmetric Standard Model Revisited

We re-examine the stop co-annihilation scenario of the Minimal Supersymmetric Standard Model, wherein a bino-like lightest supersymmetric particle has a thermal relic density set by co-annihilations with a scalar partner of the top quark in the early universe. We concentrate on the case where only the top partner sector is relevant for the cosmology, and other particles are heavy. We discuss the cosmology with focus on low energy parameters and an emphasis on the implications of the measured Higgs boson mass and its properties. We find that the irreducible direct detection signal correlated with this cosmology is generically well below projected experimental sensitivity, and in most cases lies below the neutrino background. A larger, detectable, direct detection rate is possible, but is unrelated to the co-annihilation cosmology. LHC searches for compressed spectra are crucial for probing this scenario

Qualitative Properties of alpha-Weighted Scheduling Policies

We consider a switched network, a fairly general constrained queueing network model that has been used successfully to model the detailed packet-level dynamics in communication networks, such as input-queued switches and wireless networks. The main operational issue in this model is that of deciding which queues to serve, subject to certain constraints. In this paper, we study qualitative performance properties of the well known $\alpha$-weighted scheduling policies. The stability, in the sense of positive recurrence, of these policies has been well understood. We establish exponential upper bounds on the tail of the steady-state distribution of the backlog. Along the way, we prove finiteness of the expected steady-state backlog when $\alpha<1$, a property that was known only for $\alpha\geq 1$. Finally, we analyze the excursions of the maximum backlog over a finite time horizon for $\alpha \geq 1$. As a consequence, for $\alpha \geq 1$, we establish the full state space collapse property.Comment: 13 page

Examining employee attitudes and behaviours towards organisational change using supervisor and peer relations

This study focuses on employee workplace and demographic predictors to know the employee attitudes and behaviours regarding organisational change. Five hundered fifty six surveys out of one thousand were returned from full time academics working in public sector universities of Pakistan. The findings indicate significant relationships between readiness for change and workplace and demographic factors. First time supervisor and peer relations predictor has been examined to readiness for change. Results indicate positive and significant relationships between readiness for change and supervisor and peer relations. However, from demographic characteristics only two i.e. number of dependents and younger employees have positive and significant relationships to readiness for change. This study contribute in the literature on change management particularly for developing countries i.e. Pakistan and assist the management and practitioners of human resources management (HRM), organisational development (OD) and change agents in assessing, designing and evaluating new or existing programs for organisational change

Impact of employees psychological and financial predictors for readiness to organizational change

This study focuses on employees’ psychological and financial predictors to know the employees reaction regarding change. One hundred forty one surveys were returned from full time teaching staff working in public sector universities of Pakistan. The findings indicate significant relationships between readiness to change and psychological and financial predictors. First time job involvement, training and skills development, pays/wages/fringe benefits and promotions predictors have been examined for readiness to change. Results indicate no relationship between readiness to change and employees’ organizational commitment. However, employees’ job involvement, training and skills development pays/wages/fringe benefits, and promotions have positive impact on readiness to change. This study may contribute in the literature on change management particularly for developing countries and may assist the management and practitioners of Human Resources Management (HRM), Human Resources Development (HRD), and Organizational Behaviour (OB) in assessing, designing and evaluating new or existing programs for organisational change
