Monitoring mechanisms in new product development with risk averse project manager
Venue: J. Intell. Manuf.
Year: 2017

It is necessary for one senior executive (she) to monitor her project manager (he) who conducts early research stage followed by a later development stage in new product development. In this paper, we analyze two monitoring mechanisms: (1) the idea information based monitoring (IM) mechanism wherein the senior executive engages one supervisor to monitor the project manager's idea information; (2) the effort based monitoring (EM) mechanism wherein the senior executive engages another supervisor to monitor the project manager's effort. Within the framework of uncertainty theory, we first present two classes of bilevel uncertain principal agent monitoring models, and then derive their respective optimal incentive contracts. We find that the senior executive should set the incentive term as high as possible to motivate each supervisor to monitor the project manager's idea information and effort no matter how much the design idea value is. We also find that EM mechanism can always dominate IM mechanism when the monitoring costs are equal. Moreover, comparing with a no monitoring scenario, we identify two values of monitoring: the value of monitoring idea information and the value of monitoring effort. Our results show that adopting IM and EM mechanisms can improve the senior executive's profits obtained in the no monitoring scenario when the revenue uncertainty is sufficiently low. The results also indicate that the value of monitoring idea information decreases as the risk aversion level of the project manager improves, while the value of monitoring effort shows the opposite feature.

Scalable Algorithms for CQA Post Voting Prediction
Venue: IEEE Transactions on Knowledge and Data Engineering
Year: 2017

Community Question Answering (CQA) sites, such as Stack Overflow and Yahoo! Answers, have become very popular in recent years. These sites contain rich crowdsourcing knowledge contributed by the site users in the form of questions and answers, and these questions and answers can satisfy the information needs of more users. In this article, we aim at predicting the voting scores of questions/answers shortly after they are posted in the CQA sites. To accomplish this task, we identify three key aspects that matter with the voting of a post, i.e. the non linear relationships between features and output, the question and answer coupling, and the dynamic fashion of data arrivals. A family of algorithms are proposed to model the above three key aspects. Some approximations and extensions are also proposed to scale up the computation. We analyze the proposed algorithms in terms of optimality, correctness, and complexity. Extensive experimental evaluations conducted on two real data sets demonstrate the effectiveness and efficiency of our algorithms.

Decision Support Tool for Water Reclamation Beyond Technical Considerations Egyptian, Moroccan and Tunisian Case Studies.
Venue: Integrated environmental assessment and management
Year: 2020

While the Middle East and North African region is facing challenges to sustain water security, water reclamation has received increasing consideration as a favourable mitigating solution. Despite the availability of adequate technologies; economic, political, legal, social, and environmental constraints often hamper stakeholders and especially decision makers to exploit the existing potential into implementation of solutions. In this paper, a comprehensive assessment for water reclamation and reuse was developed. This assessment consists of four objectives, namely A) applying a decision support tool (DST) for water reclamation potential for municipal wastewater, B) applying a DST for simulating and estimating lifecycle costs of project related technologies for water reclamation (municipal and industrial wastewater, drainage canal water) C) assessing the national level conditions for water reuse with a multi criteria decision analysis, and D) establishing exemplary strategies, barriers and measures for water reuse. This analysis considers six thematic subjects: policy and institution, economy, society, water management, legislation, and environment. The assessment was applied to food and non food crop irrigation in Egyptian, Moroccan, and Tunisian case studies. For all defined case studies, adapted treatment trains that could treat wastewater to the desired quality at reasonable costs were identified and are presented in this paper. The results show that technological options are available for water reuse, but the concept is not widely implemented in Egypt, Morocco, and Tunisia. This paper identifies key barriers and drivers for the implementation of water reclamation for irrigation. In particular, the considered countries show different characteristics regarding efficient water management, water pricing, subsidies and wastewater tariffs, implementation of monitoring and reporting systems or legal aspects related to the use of reclaimed water for food crop irrigation. Further exploration of case studies on high potential water reuse and financially affordable wastewater reclamation, particularly case studies that explore the impacts of policies and practices across countries, would be useful to help the Middle East and North African region improve its water security situation.

Socio demographic determinants of anaemia and nutritional status in the Democratic Republic of Congo, Uganda and Malawi
Year: 2013

Anaemia is a worldwide public health concern. Anaemia is multifactorial and its related factors are classified according to their position in the pathophysiological process. Socioeconomic and demographic factors such as poor education, cultural norms such as food taboos can predispose children and women to anaemia through immediate causes such as physiological, biological, diet and infections. However, socioeconomic and demographic factors associated with anaemia are not widely reported and it is difficult to find published literature on this subject, which could be due to the lack of data. The objective of this research is to provide an understanding of socioeconomic and demographic factors related with anaemia among children and women and the links between anaemia during childhood and child nutritional status which can be used as a basis for policy formulation, planning and implementation. Almost three quarters of children and half of women in DRC (2007) Uganda (2006) and Malawi (2004) are anaemic. Multilevel ordinal regression models were fitted for anaemia among children and multilevel logistic regression models for anaemia among women. The models showed variations in anaemia prevalence within the countries at the community level. However, country level interactions indicate that there are no significant differences in the risk of anaemia in children and women between these countries. Endogenous switching regression models were fitted to the data to explore the link between anaemia and child's health outcomes. Anaemia is endogenous to children's nutritional status (weight for age z scores) which should be accounted for. The prevalence of anaemia is high in DRC (71% Uganda (74% and Malawi (73% and anaemia is a severe public health problem in the three countries. Although it will take considerable time for the three countries to control anaemia, it is not an impossible task. By improving nutrition and iron status, and treating helminth and malaria infections, the prevalence of anaemia can decrease as observed in Malawi in 2010. More effort is needed to identify the pathways through which anaemia within each country may be addressed.
Optomechanical sensing with on chip microcavities
Year: 2013

The coupling between optical and mechanical degrees of freedom has been of broad interest for a long time. However, it is only until recently, with the rapid development of optical microcavity research, that we are able to manipulate and utilize this coupling process. When a high Q microcavity couples to a mechanical resonator, they can consolidate into an optomechanical system. Benefitting from the unique characteristics offered by optomechanical coupling, this hybrid system has become a promising platform for ultrasensitive sensors to detect displacement, mass, force and acceleration. In this review, we introduce the basic physical concepts of cavity optomechanics, and describe some of the most typical experimental cavity optomechanical systems for sensing applications. Finally, we discuss the noise arising from various sources and show the potentiality of optomechanical sensing towards quantum noise limited detection.
Covid 19 and fatigue a game of snakes and ladders
Year: 2020

It's over, I thought! It was the beginning of May, after the weirdest seven weeks of illness I had ever had, a roller coaster of exhaustion, pain everywhere, tinnitus, headaches, and fog: I felt remarkably well, almost high. The aches had gone, my mind was alive, the sun was out. I wrote in an earlier opinion piece: "And today the disease has lifted."
Varus Gonarthrosis Predisposes to Varus Malalignment in TKA
Venue: HSS Journal
Year: 2009

Postoperative alignment is a predictor for long term survival of total knee arthroplasty (TKA) The purpose of this study was to evaluate whether or not preoperative deformities predispose to intraoperative malposition of TKA components. A retrospective radiographic analysis of 53 primary TKA cases was performed. Preoperative AP hip to ankle and lateral knee radiographs were compared with postoperative views to evaluate component positioning. The following angles were measured: the hip knee ankle (HKA) angle expressing the mechanical axis of the leg, the mechanical lateral distal femur angle (mLDFA) the medial proximal tibia angle (MPTA) the posterior distal femur angle (PDFA) and the posterior proximal tibia angle (PPTA) Postoperative measurement of the HKA revealed 34.0% of the cases had a deviation of 3deg from neutral alignment. Sixteen knees (30.2% were in varus and, with one exception, all presented with severe varus gonarthrosis prior to surgery with a mean tibiofemoral angle of 12.4deg compared with 1.0deg of valgus in the optimally aligned group. Patients (93.3% with preoperative valgus malalignment showed optimal postoperative HKA. Odds ratios for malalignment of TKA for varus knees in comparison with valgus knees were 7.1 for HKA, 2.4 for MPTA, 4.9 for PDFA, and 1.7 for PPTA. The overall number of outliers in the presented data corresponds well with reports from other authors using different implants and guide systems. The presented data indicate that patients with preoperative varus alignment have a higher risk of postoperative implant malposition than patients with valgus alignment. The data supports that preoperative varus deformity predisposes to varus malposition of TKA. The risk for intraoperative malposition is significantly lower in valgus knees.
Are a "can do" Attitude and a can of Red Bull Enough? Workload and Fatigue in High stakes, High demand Carrier Sortie Operations
Year: 2015

The purpose of this investigation was to examine the role of fatigue and crew endurance in human performance of Carrier Sortie requirements; this mission capability involves high stakes, high demand, high tempo operations in a challenging maritime environment. The researchers engaged with a panel of Nimitz crewmembers for a discussion of workload, notional schedules, and endurance risk factors. Workload was examined with models that consider the human capacity for sustaining. The investigation found that more attention is paid to physical fatigue, compared to cognitive or mental fatigue. Crewmembers emphasized that crew has a "can do" attitude to combat fatigue; the crew stated that "pride and adrenaline overpower fatigue..plus coffee and Red Bull." They indicated that this results in good initiative, but at times bad judgment while trying to accomplish the work. The current research posits that fatigue is likely to reduce the ability of crewmembers to tolerate sustained performance and associated increased physiological and cognitive costs. However, the authors also recognize the limits of fatigue science with regard to predicting human capacity in intense operational and combat conditions. There is much anecdotal information to suggest that sailors are managing fatigue despite the predictions of various fatigue models. As a result, we cannot yet predict with certainty when the accumulated workload and fatigue of the individual sailor will be untenable, or identify critical thresholds of degraded cognitive capacity and decision making. Rather than rely solely on fatigue prediction software, it is recommended that potential mitigations are considered that might provide the crew more tools to manage endurance as a fatigue abatement strategy. The development of a crew endurance program to mitigate the risks posed by fatigue and reduced alertness during carrier sortie operations would identify risks relating to fatigue and alertness, and generate solutions to mitigate these risks by controlling exposure to endurance risk factors during normal operations so that the crew will be better prepared to respond to any operational demand.
Men's Depression and Suicide
Venue: Current Psychiatry Reports
Year: 2019

To explore recent research evidence addressing men's depression and suicide. Included are discussions of recent literature investigating male depression symptoms, and men's depression and suicidality help seeking and engagement with professional mental health care services. Specific externalizing symptoms of substance misuse, risk taking, and poor impulse control among men indicate the need for gender sensitized depression screening and risk assessments. The reticence of some men for seeking professional health care has drawn public awareness raising and de stigmatizing efforts, while clinical guidelines for working with boys and men have been offered to better serve men seeking help for depression and/or suicidality. There is a strengthening case for male depression comprising specific externalizing symptomology, and these findings, along with high male suicide rates (including men who are seemingly in care) indicate the need for tailored approaches to men's depression and suicide prevention.

4D BIM Based Workspace Planning for Temporary Safety Facilities in Construction SMEs
Venue: International journal of environmental research and public health
Year: 2020

Temporary safety facilities (TSFs) are an essential support system providing necessary protection to workers during construction activities, which are targeted towards preventing the occurrence of incidents and accidents at the construction site; however, the schedule and location of installation and demolition of TSFs continue to rely on labor experience, and are often omitted from formal drawings or documents. This results in thousands of accidents in the construction industry, especially in construction small and medium sized enterprises (SMEs) because of their several limiting factors; therefore, this study proposes automatic workspace planning for TSFs based on construction activities, which is a systematized approach for construction SMEs to practice occupational health and safety (OHS) By using building information modeling (BIM) and add in algorithm, safety facilities can be simulated and visualized to integrate into the designated workspace. The developed system was implemented utilizing 4D BIM for TSFs installation and validated with a case study on a residential building project. The result revealed that the visualized TSF produces a better understanding of safety measures with regard to project schedule. Additionally, TSFs workspace planning provides an affordable approach that motivates safety practices among the SMEs; consequently, the effectiveness of construction safety measures and their management is enhanced appreciably.
The Runes of Evolution: How the Universe became Self Aware
Year: 2015

How did human beings acquire imaginations that can conjure up untrue possibilities? How did the Universe become self aware? In The Runes of Evolution, Simon Conway Morris revitalizes the study of evolution from the perspective of convergence, providing us with compelling new evidence to support the mounting scientific view that the history of life is far more predictable than once thought. A leading evolutionary biologist at the University of Cambridge, Conway Morris came into international prominence for his work on the Cambrian explosion (especially fossils of the Burgess Shale) and evolutionary convergence, which is the process whereby organisms not closely related (not monophyletic) independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. In The Runes of Evolution, he illustrates how the ubiquity of convergence hints at an underlying framework whereby many outcomes, not least brains and intelligence, are virtually guaranteed on any Earth like planet. Conway Morris also emphasizes how much of the complexity of advanced biological systems is inherent in microbial forms. By casting a wider net, The Runes of Evolution explores many neglected evolutionary questions. Some are remarkably general. Why, for example, are convergences such as parasitism, carnivory, and nitrogen fixation in plants concentrated in particular taxonomic hot spots? Why do certain groups have a particular propensity to evolve toward particular states? Some questions lead to unexpected evolutionary insights: If bees sleep (as they do) do they dream? Why is that insect copulating with an orchid? Why have sponges evolved a system of fiber optics? What do mantis shrimps and submarines have in common? If dinosaurs had not gone extinct what would have happened next? Will a saber toothed cat ever re evolve? Conway Morris observes: "Even amongst the mammals, let alone the entire tree of life, humans represent one minute twig of a vast (and largely fossilized) arborescence. Every living species is a linear descendant of an immense string of now vanished ancestors, but evolution itself is the very reverse of linear. Rather it is endlessly exploratory, probing the vast spaces of biological hyperspace. Indeed this book is a celebration of how our world is (and was) populated by a riot of forms, a coruscating tapestry of life." The Runes of Evolution is the most definitive synthesis of evolutionary convergence to be published to date.
Interaction Effects of Disruptive Behaviour and Motivation Profiles with Teacher Competence and School Satisfaction in Secondary School Physical Education
Venue: International journal of environmental research and public health
Year: 2019

The objectives of this work were two fold: Firstly, to identify the profiles of disruptive behaviours and motivation in secondary school physical education students using cluster analysis; and secondly, to analyse the interaction of the profiles with school satisfaction and perceived teaching competence. A group of 758 secondary school students (54.2% female) between the ages of 13 and 18 (M 15.22, DT 1.27) participated in the study by responding to the following scales: The Disruptive Behaviours in Physical Education Questionnaire, The School Satisfaction Scale, The Sport Motivation Scale adapted to Physical Education, and the Evaluation of Teaching Competencies Scale in Physical Education. The cluster analysis established two distinct profiles: High levels of disruptive behaviours and low levels of disruptive behaviours. The results showed that the students with the high disruptive behaviours profile were mostly boys, having low levels of intrinsic motivation and high levels of amotivation and misbehaviour in the classroom. In contrast, those students with the low disruptive behaviours profile were mostly girls, having the highest levels of intrinsic motivation and the lowest levels in all the disruptive behaviours. It was shown that students exhibiting the worse classroom behaviours were more bored in school, while those students with better behaviour perceived greater teaching competence.
