A Polynomial Approach to the MIMO LQ Servo and Disturbance Rejection Problems *

A l~ t r~e t -A novel matrix fraction solution to the discretetime LQ stochastic tracking and servo problems is extended to the disturbance rejection problem. Unlike recent contributions, here the resulting control law at time t is given in terms of an expectation conditioned to the accessible disturbance given up to time t + k. If k is positive and large enough, the optimal feedforward input can be tightly approximated without requiring any stochastic model for the disturbance. If the latter is known (also for recurrent or predictable disturbance), the optimal feedforward input is obtained by solving a single bilateral Diophatine equation.
Do Managers Listen to the Market?

There are competing theories as to whether managers learn from stock prices. Dye and Sridhar (2002), for example, argue that capital markets can be better informed than the firm itself, while Roll (1986) argues managers may ignore market signals due to hubris. In this paper, we examine whether managers listen to the market in making major corporate investments, and whether agency costs and corporate governance mechanisms help explain managers' propensity to listen. We find that, on average, managers listen to the market: they are more likely to cancel investments when the market reacts unfavorably to the related announcement. Further, we find mixed evidence consistent with the notion that managers' propensity to listen is related to agency costs. We find that firms tend to listen to the market more when more of their shares are held by large blockholders, and when their CEOs have higher pay-performance sensitivities.
Effect of Service Quality on Customers Satisfaction: An Application of HEdPERF Model

The aim of this study was to measures the effect of service quality on customer satisfaction. There are 384 respondents were selected from 19 universities of Khyber Pakhtunkwa (Pakistan). The proportionate stratified sampling method was used for the collection of data. The collected data was analysed using SPSS and AMOS packages. Exploratory Factor, Confirmatory Analysis and Parallel Analysis were also performed. Structural Equation Modelling technique was used to investigate the relationship among variables under investigation. Findings of the research reveals that majority of the respondents were satisfied with the dimensions of HEdPERF model in universities of Khyber Pakhunkhwa (Pakistan). The dimension academic was ranked the most important dimension of service quality. Thus, this unique finding implies that universities should nurture the academic quality rigorously in order to enhance students’ satisfaction without ignoring the remaining dimension of service quality.
Paediatric life-limiting conditions: Coping and adjustment in siblings

A total of 31 siblings, aged between 5 and 16 years, of children with a life-limiting condition, participated in a longitudinal, mixed method study. Data collection included standardised psychometric measures and visual and participatory qualitative methods. Emotional functioning and perceptions of self-worth were normative on standardised measures. Qualitative data indicated distinct psychosocial strategies that appeared to underpin functioning, positioning themselves as adults within the family, adopting a role of ‘social glue’ in key relationships and thereby diminishing their own needs, and compartmentalising home and school life. Some strategies appeared adaptive in the short term but may be limiting in the longer term. The implications for professionals working to support families are discussed.
Off‐The‐Job Training and the Shifting Role of Part‐Time and Temporary Employment Across Institutional Models. Comparing Italian and British Firms

This article investigates intensity and composition of off-the-job training investments of Italian and British firms in relation to their workforce heterogeneity with respect to the presence of non-standard workers. The main purpose is to assess the relationship between off-the-job training volumes and composition and the recourse to the main types of non-standard employment, i.e. temporary and part-time contracts, at firm level. Empirical evidence drawn from national surveys of the two countries shows more similarities than expected in terms of the correlation between non-standard employment and training volumes whilst substantial differences arise when disaggregating training interventions according to the types of skills to be developed. Both institutional settings and the different role of part-time and temporary employment in the labour markets of the two countries contribute to interpretation of results.
FIXED-POINT CONTINUATION APPLIED TO COMPRESSED SENSING: IMPLEMENTATION AND NUMERICAL EXPERIMENTS *

Fixed-point continuation (FPC) is an approach, based on operator-splitting and continuation, for solving minimization problems with ‘1-regularization: minkxk1 + f (x): We investigate the application of this algorithm to compressed sensing signal recovery, in which f(x) = 1 kAx bk 2 , A2 R m n and m n. In particular, we extend the original algorithm to obtain better practical results, derive appropriate choices forM and under a given measurement model, and present numerical results for a variety of compressed sensing problems. The numerical results show that the performance of our algorithm compares favorably with that of several recently proposed algorithms.
What Drives Virality (Sharing) of Online Digital Content? The Critical Role of Information, Emotion, and Brand Prominence

The authors test five theoretically derived hypotheses about what drives video ad sharing across multiple social media platforms. Two independent field studies test these hypotheses using 11 emotions and over 60 ad characteristics. The results are consistent with theory and robust across studies. Information-focused content has a significantly negative effect on sharing, except in risky contexts. Positive emotions of amusement, excitement, inspiration, and warmth positively affect sharing. Various drama elements such as surprise, plot, and characters, including babies, animals, and celebrities arouse emotions. Prominent (early vs. late, long vs. short duration, persistent vs. pulsing) placement of brand names hurts sharing. Emotional ads are shared more on general platforms (Facebook, Google+, Twitter) than on LinkedIn, and the reverse holds for informational ads. Sharing is also greatest when ad length is moderate (1.2 to 1.7 minutes). Contrary to these findings, ads use information more than emotions, celebrities more than babies or animals, prominent brand placement, little surprise, and very short or very long ads. A third study shows that the identified drivers predict sharing accurately in an entirely independent sample.
Association of pretransplant serum phosphorus with posttransplant outcomes.

BACKGROUND AND OBJECTIVES Serum phosphorus levels are associated with mortality, cardiovascular disease, and renal function loss in individuals with and without chronic kidney disease. The association of pretransplant serum phosphorus levels with transplant outcomes is not clear. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Data of the Scientific Registry of Transplant Recipients (SRTR) up to June 2007 were linked to the database (2001 through 2006) of one of the U.S.-based large dialysis organizations (DaVita). The selected 9384 primary kidney recipients were divided into five groups according to pretransplant serum phosphorus levels (mg/dl): <3.5, 3.5 to <5.5 (reference group), 5.5 to <7.5, 7.5 to <9.5, and ≥9.5. Unadjusted and multivariate adjusted risks for transplant outcomes were compared. RESULTS Patients were 48 ± 14 years old and included 37% women and 27% African Americans. After multivariate adjustment, all-cause and cardiovascular death hazard ratios were 2.44 (95% confidence interval: 1.28 to 4.65) and 3.63 (1.13 to 11.64), respectively, in recipients in the ≥9.5 group; allograft loss hazard ratios were 1.42 (1.04 to 1.95) and 2.36 (1.33 to 4.17) in recipients with 7.5 to >9.5 and ≥9.5, respectively. No significant association with delayed graft function was found. CONCLUSIONS Pretransplant phosphorus levels 7.5 to <9.5 mg/dl and ≥9.5 mg/dl were associated with increased risk of functional graft failure and increased risk of all-cause and cardiovascular deaths, respectively, when compared with 3.5 to <5.5 mg/dl. Additional studies are needed to examine whether more aggressive control of pretransplant serum phosphorus may improve posttransplant outcomes.
New drugs for systemic fungal infections.

This underlines the importance of correct interpretation of the article. The white paper says that "it is difficult to see, for example, how recommendations as to the medical professions which are designed to ensure patient health, safety and wellbeing could not be said to be in the interest of the consumers of the services, according to these criteria. " One can only observe that this is stretching the law of construction and interpretation of documents to its limits. Unlike the green paper, the white paper is anxious to establish that restrictions that "enforce objectively justified standards" should not be caught by the prohibition "because, in the majority of cases, rules designed to maintain standards of competence or professional practice do not restrict competition between those who are competent to offer the service. " Characteristically the example is given of the restriction on the provision of unnecessary treatment-which has an obvious economic justification. Non-statutory rules of professional bodies "which are designed to do no more than to avoid conflict of interest or other practices which would undermine the integrity ofthe profession, or affect the public's confidence in it" are also stated to be exempt, although how they can possibly qualify within the article is not explained. The government has rejected the BMA's strong objection to the draconian powers of entry into the premises of both practices and professional associations "to obtain information" as set out in the green paper. Assurances are given that access "would extend only to management files of the practice in order to confirm the existence of an illegal agreement between members of the profession concerned. " These powers would be ruled unconstitutional in any civil law country in Europe. Outside the public sector it seems unlikely that the BMA's activities in recommending standard fees for medical services will escape, unless a block exemption is obtained for medical services. The government has ignored the argument that a doctor's time would be better spent looking after patients than in negotiating each and every fee for each and every service by each and every agency that requests it. Meanwhile we must be thankful that there will be transitional provisions to allow for the production of guidance and block exemptions before the heavy penalties and civil actions (to which the BMA objected strongly) come into force.
rf surface resistance of Y-Ba-Cu-O thin films.

The rf surface resistance of superconducting Y-Ba-Cu-O thin films has been measured using a stripline resonator technique. The electron-beam-evaporated films have been measured from 0.6 to 17.4 GHz and from 4.2 to 8 K. The surface resistance reaches as low as 3.9 x 10/sup -4/ . cap omega. at the lowest frequency, and is expected to improve significantly as the film quality is optimized.
Giant Axonal Neuropathy: Combined Central and Peripheral Nervous System Disease

A 6-year-old Japanese boy with curly hair since birth appeared to be normal until age 3, when his gait became clumsy. At age 5, pes equinus appeared bilaterally. At age 6, clumsiness in buttoning and writing was detected. Although he could stand up with¬ out assistance of the upper extremities, he could only climb stairs step by step. Examination on admission at age 6Vs> years disclosed weakness and atrophy of the legs. Gait was waddling and unsteady, and he could not walk on heel or toe or in tandem fashion. Vibratory sense was reduced in the legs. Muscle stretch reflexes
Health care sought and received by men with urinary symptoms, and their views on prostatectomy.

BACKGROUND Urinary symptoms are common among middle aged and elderly men. AIM A study was undertaken to describe the health care sought by men aged 55 years and over with urinary symptoms, the action taken by general practitioners and urologists, and the men's views on prostatectomy. METHOD A postal questionnaire was sent to 516 men aged 55 years and over in the North West Thames Regional Health Authority, with previously identified mild, moderate or severe urinary symptoms. RESULTS The response rate among eligible subjects was 83%. Of 420 respondents 45% had seen their general practitioner for their symptoms. General practitioners had referred 62% of these men to a urologist, reassured 21% and prescribed medication to 17%. The probability of a man seeking medical advice increased with increasing symptom severity. In contrast, the decision to refer was independent of symptom severity. Of the men referred to a urologist, the majority (71%) were offered and accepted surgery. The remainder were reassured (17%), or received a prescription (4%). Eight per cent were offered surgery but declined. When presented with details and information on the risks and benefits of prostatectomy, 22% of men with symptoms would probably or definitely refuse treatment, while a further 47% of men were unsure. CONCLUSION There are many men who do not seek treatment for urinary symptoms and, of those who do, subsequent referral is not associated with symptom severity. There is scope for improving the referral process through the shared development of guidelines between general practitioners, hospitals and commissioning agencies.
The relationship between intravenous infusate colonisation and fluid container hang time

Aims. To examine the level of microbial colonisation in intravenous fluids after 24 hours of use in an acute care setting to determine the necessity of changing infusate bags on a timerelated basis. Background. Catheter-related bloodstream infections are a serious and life-threatening complication of intravascular devices. Colonised intravenous fluids are one potential source of infection; however, there is little published literature on incidence rates and few recent studies. Routine intravenous fluid replacement has been advocated as an infection control method, but the effectiveness of this is unknown and the optimal duration for infusate use remains uncertain. Design. Cross-sectional study over 18 months in a 257-bed teaching hospital. Methods. Infusate specimens (n=264) were obtained from crystalloid fluids that had been used for 24 hours or more. Microbiological culture and sensitivity testing was performed and infusate-related bloodstream infection rates were recorded. Sample testing of previously unopened intravenous solutions acted as a control. Results. The infusate colonisation rate was 0.4%, or 0.09 per 1,000 infusion hours. The only isolated organism was coagulase-negative Staphylococcus. Infusions had been in use for 24185 hours (1-8 days). There was no difference in median duration of use for colonised (35.0 hours) and sterile (34.0 hours) specimens (Mann-Whitney test, p=0.99). There were no cases of infusate-related bloodstream infection. Conclusion. The incidence of intravenous fluid colonisation and the risk of related bloodstream infection are low even after several days of infusate use. Current practice appears to successfully maintain the sterility of intravenous fluids. Relevance to clinical practice. Routine replacement of intravenous fluids continues in many settings, often 24 hourly, in the belief that this prevents infection. We found no Infusate colonisation 3 relationship between duration of use and colonisation and routine replacement may be unnecessary. Further research is needed to investigate the effectiveness of routinely replacing intravenous fluids at set time points to prevent colonisation and infection.
Prediction of post‐extubation work of breathing

Objective: To evaluate which mode of preextubation ventilatory support most closely approximates the work of breathing performed by spontaneously breathing patients after extubation. Design: Prospective observational design. Setting: Medical, surgical, and coronary intensive care units in a university hospital. Patients: A total of 22 intubated subjects were recruited when weaned and ready for extubation. Interventions: Subjects were ventilated with continuous positive airway pressure at 5 cm H2O, spontaneous ventilation through an endotracheal tube (T piece), and pressure support ventilation at 5 cm H2O in randomized order for 15 mins each. At the end of each interval, we measured pulmonary mechanics including work of breathing reported as work per liter of ventilation, respiratory rate, tidal volume, negative change in esophageal pressure, pressure time product, and the airway occlusion pressure 100 msec after the onset of inspiratory flow, by using a microprocessor‐based monitor. Subsequently, subjects were extubated, and measurements of pulmonary mechanics were repeated 15 and 60 mins after extubation. Measurements and Main Results: There were no statistical differences between work per liter of ventilation measured during continuous positive airway pressure, T piece, or pressure support ventilation (1.17 ± 0.67 joule/L, 1.11 ± 0.57 joule/L, and 0.97 ± 0.57 joule/L, respectively). However, work per liter of ventilation during all three preextubation modes was significantly lower than work measured 15 and 60 mins after extubation (p < .05). Tidal volume during pressure support ventilation and continuous positive airway pressure (0.46 ± 0.11 L and 0.44 ± 0.11 L, respectively) were significantly greater than tidal volume during both T‐piece breathing and spontaneous breathing 15 mins after extubation (p < .05). Negative change in esophageal pressure, the airway occlusion pressure 100 msec after the onset of inspiratory flow, and pressure time product were significantly higher after extubation than during any of the three preextubation modes (p < .05). Conclusions: Work per liter of ventilation, negative change in esophageal pressure, the airway occlusion pressure 100 msec after the onset of inspiratory flow, and pressure time product all significantly increase postextubation. Tidal volume during continuous positive airway pressure or pressure support ventilation overestimates postextubation tidal volume.
PERSPEKTIF SUMBER DAYA MANUSIA PARIWISATA DI ERA REVOLUSI INDUSTRI 4.0

ABSTRAK Perkembangan teknologi membawa atmosfir perubahan pada semua aspek kehidupan manusia terutama perubahan pola hubungan manusia, tadinya saling berjabat tangan saat bertransaksi, berhadap-hadapan wajah (face to face) berubah drastis transaksi hanya cukup dengan sentuhan melalui layar hand phone, berkomunikasi tidak cukup mendengarkan suara tetapi bisa juga saling bertatapan wajah melalui screen to screen, dengan dalih mudah dan efesien. Ini merupakan pertanda telah hadir era revolusi industri keempat atau industry 4.0. Kemajuan ilmu pengetahuan di bidang teknologi turut memberi warna tersendiri bagi perkembangan dunia usaha, sebab beberapa jenis industri telah menggunakan teknologi internet dalam proses produksinya tidak terkecuali industri dibidang pariwisata, cukup dengan mesin pencari google bertipe voice search atau aplikasi tertentu sudah bisa mem-bantu untuk menemukan yang dibutuhkan, seperti hotel, travel, restoran, bahkan jarak tempuh suatu destinasi wisata, harga makan dan minuman dan lain sebagainya dapat ditemukan dengan cepat. Timbul kecemasan jika penerapan teknologi ini akan mereduksi manusia sebagai tenaga kerja, terlebih lagi tenaga kerja dalam bidang pariwisata. Kata kunci: Perspektif, Sumber Daya Manusia Pariwisata, Industry 4.0 ABSTRACT The development of technology brings an atmosphere of change in all aspects of human life, especially changes in human relations patterns, formerly shaking hands when transacting, face to face changing dramatically enough transactions by touch through cellphone screens, communicating not enough listening voice but can also face each other face to face through screen to screen, with the pretext of easy and efficient. This is a sign that there has been a fourth industrial revolution era or industry 4.0. The progress of science in the field of technology also gives its own color for the development of the business world, because some types of industries have used internet technology in the production process, including the industry in tourism, with the google search engine type voice search or certain applications can help find what is needed, such as hotels, travel, restaurants, even the distance of a tourist destination, the price of food and drinks and so on can be found quickly. Anxiety arises if the application of this technology will reduce humans as labor, moreover the workforce in the field of tourism. Keywords: Perspective, Human Resources Tourism, Industry 4.0
Mineralogy and partial melting of fenitized crustal xenoliths in the Oldoinyo Lengai carbonatitic volcano , Tanzania

Progressive stages of fenitization are recorded in nine xenoliths of metagranitic and metagabbroic basement that were caught up in alkali carbonatitic magma in the Oldoinyo Lengai volcano, Gregory Rift, Tanzania. The ultimate product of fenitization of the two rock types contains sanidine, nepheline and aegirine-augite. Temperatures of approximately 800'C were attained during metasomatism. Disequilibrium melting of the highest-grade assemblages occurred along grain margins, followed by a rapid quench, which prevented homogenization of melt compositions and devitrification. Such anatectic reactions involving a strongly metasomatized lower crust may be responsible for the juxtaposition of phonolitic and alkali carbonatitic melts with mantle-derived nephelinitic magmas at Oldoinyo Lengai.
The Effects of LAIV on Nasopharyngeal Bacteria in Healthy 2-4 Year Olds: a Randomized Controlled Trial.

Rationale Viral infections of the upper respiratory tract may influence the commensal nasopharyngeal bacteria. Changes in the bacterial niche could affect transmission dynamics. Attenuated vaccine viruses can be used to investigate this empirically in humans. Methods We used trivalent Live Attenuated Influenza Vaccine (LAIV) to evaluate the effects of viral infection on bacterial carriage and density of S.pneumoniae, M.catarrhalis, H.influenzae and S.aureus . 151 healthy children were randomized 1:1 to receive the vaccine starting either at recruitment (n=74) or 28 days later (n=77) in a stepped wedge fashion, allowing comparisons between recipients and non-recipients as well as whole-group comparisons pre-and post-vaccination. Bacterial carriage and density were determined using qPCR assays. Measurement & Main Results 151 children were recruited, 77 in the LAIV group and 74 controls. LAIV recipients (n=63 analysed) showed an apparent transient increase in H.influenzae carriage but no further significant differences in carriage prevalence of the four bacterial species compared to controls (n=72 analyzed). S.pneumoniae density was substantially higher in vaccine recipients (16687 vs 1935 GC/ml) 28 days after the first dose (p<0.001). Whole-group multivariable analysis (pre-vaccine, after one dose and after two doses) also showed increases in density of other species and H. influenzae carriage prevalence. Conclusion In the absence of any safety signals despite widespread use of the vaccine, these findings suggest that bacterial density and thus, transmission rates amongst children and to other age groups may rise following attenuated influenza infections without associated clinical disease. LAIV could therefore be used as an experimental tool to elucidate the dynamics of transmission of nasopharyngeal bacteria.
