The development and evaluation of a partial talent management competency model

This study was driven by a need that was identified within a large telecommunications organisation to establish the Talent Management competencies required of line managers, and to provide HR managers with a measure to constructively, rationally and purposefully manage the Talent Management performance of line managers. In an attempt to address the above research needs, the study set about to 1) identify the Talent Management competencies required by line managers in order to successfully implement the organisation’s Talent Management strategy; 2) formulate these competencies within a model, and 3) determine what the desired Talent Management outcomes are and how these relate to line managers’ Talent Management competencies. The initial part of this study describes the development of a Talent Management competency 360° evaluation questionnaire. This objective was achieved by means of a literature search, followed by the Critical Incidents Technique (CIT) of interviewing. The questionnaire consists of 8 dimensions and 43 items. The sample consisted of 123 leadership development candidates within this organisation. A total of 357 questionnaires were obtained. A comprehensive Talent Management competency model was developed that defines and describes the line manager behaviours required in order to successfully carry out the Talent Management strategies within an organisation. These competencies were evaluated against the outcomes of Job Satisfaction, Affective Commitment and Intention to Quit that the Talent Management competencies are meant to affect. Item analysis and dimensionality analysis were performed on each of the subscales, using SPSS. Thereafter, confirmatory factor analysis was performed on the relevant measurement model data sets, using LISREL. The results indicated in all cases satisfactory measurement model fit. Subsequently, the comprehensive Talent Management competency structural model was tested using LISREL. Reasonable to good model fit was indicated for the structural model. Ten of the 24 stated hypotheses in this study were corroborated. A notable unique result of this research presented itself in the significant positive relationships uncovered between the exogenous latent variable, Talent Management Mindset, and the endogenous latent variables of Attracts and Recruits Talent, Builds and Maintains
Resistance of soil to a horizontally vibrating pile

The resistance of a soil layer to steady horizontal vibration of an elastic pile is theoretically investigated. The pile is assumed to be vertical and of circular cross-section. The soil is modelled as a linear viscoelastic layer with hysteretic material damping. A closed form solution is obtained for the resistance of the soil layer to the motion. This resistance depends on shear modulus of soil, frequency, pile slenderness, material damping and Poisson's ratio. A parametric study of the effect of these parameters is included. The soil layer resistance is expressed in a form which can be used directly in the solution of the soil-pile interaction problem which is treated in a subsequent paper. The approach also applies for rigid deeply embedded footings.
TME Volume 13, Numbers 1 and 2

Although the field lacks a theoretically grounded, well-defined, and shared conception of mathematical knowledge required for teaching, there appears to be broad agreement that a specialized body of knowledge is vital to improvement. Further, such a construct serves as the foundation for different kinds of studies with different agendas. This article reviews what is known and needs to be known to advance research on mathematical knowledge for teaching. It argues for three priorities: (i) finding common ground for engaging in complementary studies that together advance the field; (ii) innovating and reflecting on method; and (iii) addressing the relationship of such knowledge to mathematical fluency in teaching and to issues of equity and diversity in teaching. It concludes by situating the articles in this special issue within this emerging picture.
Evaluation of enhanced design and build system a case study of a hospital project

This study involves an investigation of a hospital project which adopted an ‘enhanced design and build’ form of building procurement. The paper assesses the procurement system from the perspectives of the client, client's consultants, contractor, contractor's consultants, and contractor's subcontractors. A detailed case study of North District Hospital is described to illustrate the process of this procurement system. All the interviewees generally agreed that the hospital project was successful in meeting the time, cost, quality, functional and safety requirements set by the client. As the first project adopting the ‘enhanced design-build’ procurement system in Hong Kong, the benefits of applying this innovative procurement system were demonstrated.
Determining the Causes of Delay by Using Factor Analysis in Tehran’s Construction Projects

Construction industry is one of the most profitable sectors in Iran’s economic. Delay is common problem in the construction projects in Iran. By considering all viewpoints of the parties, this research identified the most effective and severe causes of delay in construction projects in the Capital of Iran, Tehran. Questionnaires were distributed among respondents who are involved in the construction project in Tehran. The process of data analysis and discussions were conducted based on the two statistical techniques namely descriptive analysis (RII) and factor analysis. Using factor analysis, most critical factors of Tehran’s construction delay were recognized as: (1) lack of commitment; (2) inefficient site management; (3) poor site coordination; (4) Complexity in heritage and legislation; (5) Lack of estimation skills and skilled workers; (6) Lack of communication between parties; (7) Improper planning; and (8) Lack of clarity in contract. These results are anticipated to be important contributions to construction projects in Tehran in controlling the time overruns in construction contracts.
ACCEPTANCE CRITERIA FOR BOND QUALITY OF STRAND FOR PRETENSIONED PRESTRESSED CONCRETE APPLICATIONS

In this test program, 6 samples of 0.5 in. (13 mm) diameter strand were obtained from precast, prestressed concrete producers from widely separated regions of North America to evaluate strand bond performance. A total of 216 tests were carried out on the specimens, including pull-out tests, end slip at prestress release and at 21 days, as well as development length tests. The pull-out test proved to be an accurate predictor of the general transfer and development characteristics of the strand in pretensioned, prestressed concrete applications. Based on the test results, the following major findings can be drawn: 1) the transfer and development lengths of strands with average pull-out capacity exceeding 36 kips (160 kN) were considerably shorter than predicted by the ACI transfer and development length equations; 2) strands with average pull-out capacity less than 12 kips (53.3 kN) were unable to meet the ACI transfer length criteria, and failed prematurely in bond at the ACI development length, without noticeable warning deflection.
Design of Multiple Cause-Selecting Charts for Multistage Processes with Model Uncertainty

Abstract The cause-selecting chart (CSC) is an effective statistical process control tool for monitoring multistage processes. The multiple cause-selecting chart (MCSC) is the further development of the CSC, which deals with the case when the output measure is a function of multiple input measures. In practice, the model relating the input and output measures often needs to be estimated before the MCSC is implemented. However, the traditional design of MCSCs does not take parameter uncertainties into account when estimating the control limits. The actual false-alarm rate can substantially differ from what is expected. This article presents the design and implementation of MCSCs using prediction limits to account for parameter uncertainties. These limits are developed using two types of procedures: the least-squares estimation and principal component regression. The simulation results show that the prediction limits are quite effective in terms of maintaining a desired false-alarm rate.
Multisectional modeling of high-speed electrooptic modulators integrated in a microwave circuit CAD environment

We present a new multisectional model for high-speed electrooptic modulators, fully integrated within the framework of a microwave circuit computer-aided design (CAD) suite (MWOFFICE). Starting from geometrical and layout parameters, the model allows both simple (traveling-wave) and complex (phase reversal, periodically loaded) structures to be assembled, analyzed, and optimized from the standpoint of the electrical and electrooptic response (including chirp effects) both in small-signal (analog) and in large-signal (digital) operation, exploiting standard simulator tools. At no additional effort, parasitic and passive elements (such as optical or electrical delay paths) can be directly included in the modulator schematic, and the effect of transitions and package parasitics can be readily accounted for at a circuit level. Moreover, model integration within a circuit CAD suite enables one to seamlessly perform driver and modulator design and optimization within the same monolithic or hybrid circuit environment. Comparisons with experimental and literature data and design examples are presented to validate the approach and stress its potential in the design of high-speed electrooptic modulators.
Networks and Roles of Pro-Vice Chancellors: A study of the connectedness of PVCs in the 1994 Group of Universities.

Faced with a turbulent higher education environment senior management teams in universities seek to secure the future of their university by accessing as much information about the environment as possible, often through networks. Pro-Vice Chancellors (PVCs) are members of these teams, normally with significant responsibility for activities that are integral to the university, but very little is known about their role and the importance that connections to others might play in it. Taking a social network perspective, this thesis investigates this gap using a two stage research design. First an electronically distributed questionnaire was used to determine the connectivity between PVCs either with responsibility for research or with responsibility for teaching from the original 16 UK universities of the 1994 Group. Secondly, semistructured interviews were conducted with eight PVCs from four of these universities, to examine similarities and differences in the roles of different PVCs and the importance of connectivity for them. Network maps showed that research PVCs were cohesively linked; most were connected to at least two others, and often to many more. Conversely, PVCs with responsibility for teaching were almost wholly unconnected. Connections to other PVCs served three purposes. Occasionally they were important for personal development, otherwise they either enabled PVCs to perform her/his duties by providing information, or enhanced the performance of the university by allowing access to additional resources. It is concluded that PVCs play a boundary spanning role both internally and externally to the University. Moreover, enduring connections to other PVCs formed where opportunities existed to pursue additional resources collaboratively or when it was necessary to lobby government to protect the existing resource base from others. It was argued that these circumstances commonly occurred in the research environment but not in the teaching environment and so the observed pattern of connectivity amongst PVCs was explained.
Fully differential universal current-mode frequency filters based on signal-flow graphs method

Two new circuits of 2nd order universal frequency filter designed using signal-flow graphs method are presented. Both filters were proposed in single-ended and fully-differential forms. Multiple-output current follower (MO-CF) and digitally adjustable current amplifier (DACA) used in proposal are described in the paper. The pole frequency and the quality factor of filters can be controlled by the current gain of digitally adjustable current amplifiers suitably placed in the circuit structure. The actual function of the proposed filters is verified using PSpice simulation. Simulation results of proposed filters are also included in this paper.
Natural contamination test of insulators with DC voltage energization at inland areas

Results of tests for natural contamination of insulator strings in inland areas are discussed. Natural exposure tests with -280 kV DC voltage energization were carried out for 5 years. The following results were obtained: (1) The amount of contaminant on the bottom surface increased with the length of the exposure period, for the first year, at inland areas. Therefore, estimates of contamination severity should use data obtained for exposure periods of at least one year. (2) Insulators near the line and ground sides of a string collect more contaminant than the middle when DC voltage is applied. However, the effect of nonuniform contamination on DC withstand voltage is not as great as expected when ratios of the number of heavily contaminated insulators to that of insulator string are from 15% to 30%. (3) No significant effect of DC voltage energization on the ESDD of the middle part of insulator strings has been observed when the applied voltage is no higher than 280 kV DC. (4) A pollution severity map established for AC transmission lines can be used for the determination of design ESDD for HVDC transmission lines for inland areas without industrial contamination. (5) The maximum value of leakage current under natural conditions is less than 3 mA, and no flashover has been experienced during these 5 years for electrical stress from 90 to 120 kV/m. The application of these results to insulation design for HVDC transmission lines is discussed. >
Numerical simulation of avalanche breakdown within InP-InGaAs SAGCM standoff avalanche photodiodes

The breakdown location within a planar InP/In/sub 0.53/Ga/sub 0.47/As (InGaAs) separate absorption, grading, charge sheet, and multiplication (SAGCM) avalanche photodiode (APD), using the standoff breakdown suppression design to replace guard rings, depends on the two-dimensional (2-D) geometry of the Zn diffused well. Since the geometry of this p/sup +/ diffusion is dependent upon the surface etch, the effects of varying the etch depth (t/sub standoff/) and length of the sloped etch edge (w/sub slope/) are studied using a two-dimensional drift-diffusion simulator. It is determined that the etch depth brackets a region where center breakdown dominance is possible. To ensure center breakdown within this region it is concluded that there is a maximum value that the slope of the etch walls must not exceed.
Vereinfachte Ermittlung von Primärenergiekennwerten

Angestoßen durch die EU-Richtlinie „Gesamtenergieeffizienz von Gebäuden“ und deren Umsetzung in der Energieeinsparverordnung wird derzeit in Deutschland eine Diskussion über die richtigen Werkzeuge zur Bewertung der energetischen Effizienz von Gebäuden geführt. Weitgehend unstrittig ist dabei die Bewertung von Neubauten und größeren Sanierungen. Diskutiert werden die Methoden zur Bewertung der energetischen Qualität von bestehenden Gebäuden. Dabei müssen Zeitaufwand und Genauigkeit der Bewertung in ein möglichst günstiges Verhältnis gebracht werden. Die Frage der energetischen Bewertung bestehender Gebäude stellt sich in gleicherWeise bei der Erstellung von „ökologischen“ Mietspiegeln. Als ökologischer Mietspiegel wird plakativ ein Mietspiegel bezeichnet, der bei der Beschreibung der ortsüblichen Vergleichsmiete zusätzlich zu den üblichen Kriterien die „wärmetechnische Beschaffenheit“ als ein Maß für die energetische Effizienz von Gebäuden enthält. Ein Zuschlag für eine gute wärmetechnische Beschaffenheit verbessert die Wirtschaftlichkeit von energetischen Modernisierungen und erhöht die Mietpreisgerechtigkeit. So können marktwirtschaftliche und sozial verträgliche Anreize zur Umsetzung von energetischen Modernisierungen in Mietwohngebäuden geschaffen werden. In Darmstadt wurde der erste ökologische Mietspiegel in Deutschland auf der Basis einer empirischen Untersuchung realisiert [1]. Die statistische Analyse zeigt, daß für Wohnungen in Gebäuden mit guter Wärmedämmung und moderner Heizungsanlage signifikant eine um 0,37 €/m2 pro Monat höhere Nettomiete gezahlt wird. Ein entsprechender Zuschlag für eine „gute wärmetechnische Beschaffenheit“ wurde in den Darmstädter Mietspiegel 2003 aufgenommen. Die Zuoder Abschläge für das Merkmal „wärmetechnische Beschaffenheit“ müssen auf der Basis einer empirischen Stichprobe statistisch ermittelt werden. Bei der Mietspiegelerstellung besteht somit die Aufgabe, in kurzer Zeit die Primärenergiekennwerte für alle Gebäude der Mietspiegelstichprobe (1.000 bis 2.000 Stück) zu ermitteln. Um den zusätzlichen Zeitund Kostenbedarf für die Mietspiegelerstellung gering zu halten, sollte die energetische Bewertung der Gebäude möglichst rationell erfolgen. In dem Zusammenhang wurden vom Institut Wohnen und Umwelt (IWU) in einem von der Deutschen Bundesstiftung Umwelt DBU und der Stadt Darmstadt geförderten Forschungsvorhaben Möglichkeiten zur vereinfachten energetischen Bewertung untersucht. Näher betrachtet wurde die Ermittlung des Primärenergiekennwertes – aus dem gemessenen Heizenergieverbrauch (Verbrauchskennwert) und – über eine Berechnung (Bedarfskennwert) unter Verwendung einer vereinfachten Datenaufnahme (Kurzverfahren Energieprofil (KVEP)).
Evaluation of formulations for predicting the shear strength of concrete filled circular holes in steel plates

Abstract Since the development of perforated plate shear connectors, different formulations have been proposed to predict their shear strength. Most of these formulations were derived from standard push-tests on multiple concrete filled holes (CFH) specimens simulating specific steel-concrete composite beam applications. Aiming at a more general application of these connectors in composite structures and the understanding of the physical and geometric parameters that influence their shear strength, the present work evaluated the use of 12 different formulations to predict 92 test results of single-hole specimens extracted from the literature. Such tests were chosen because the single-hole configuration allows better isolation of the connection behavior which facilitates comparative analysis. The predictions were statistically evaluated, and it was considered that the best formulations were those that showed lower scatter of data and a correction factor closer to one. Also, it was investigated if the individual terms that constitute the formulations adequately describe or show relation to the mechanics that govern the connection. It was verified that the best statistically rated formulations were also the ones showing clearer relation to the connector mechanical behavior. Among the evaluated formulations, three were significantly better than the others for strength prediction, however, it was noted that they can be further improved by considering the influence of concrete confinement and plate thickness on the hole’s strength.
Droplet-Laden Homogeneous Turbulent Flow Over Unheated and Heated Cylinders

The dispersal of high boiling point liquid fire suppression agents around solid obstacles is investigated to obtain a better understanding of the physical processes of droplet transport in cluttered spaces. To this end, the present experimental investigation examines the flow field dynamics of grid-generated homogeneous turbulent flow over obstacles, and spray transport in such flow fields. Transport of both water droplets and aerosol particles was characterized upstream and downstream of a cylinder using particle image velocimetry (PIV). Data were obtained for the cylinder at ambient temperature and after being heated to 423 K to estimate the effects of the hot cylinder surface on droplet transport. The results indicate that smaller droplets are entrained into the recirculation region behind the cylinder while the larger droplets impact the cylinder surface, accumulate and drip off, or are transported around the surface. The flow over the heated cylinder indicates the formation of a vapor layer on the downstream side of the cylinder in the shear region between the recirculation zone and free stream. Thus, vaporization of smaller droplets near the heated cylinder surface suggests an increased probability of vapor, and reduced probability of droplet entrainment into cylinder wake region. © 2003 ASME
Modelling of corona at a high-voltage conductor under double exponential and oscillatory impulses

An alternating-current corona model is adapted to allow its application to fast transient overvoltages in coaxial geometries. An initial study of data for positive and negative lightning and switching impulses shows good agreement between the model and experiment. Application is then made to a negative corona under oscillatory impulses with frequencies of 33 and 125 kHz. The model is used to aid interpretation of the complex experimental results, and gain an insight into the underlying physical phenomena. A semiquantitative quantitative adaptation is then made to successfully simulate experimental data. The model is shown to be applicable to all voltage types including direct, alternating and impulse voltages.
OPTIMIZING RECEIVERS FOR GROUND BASED MM-WAVE RADIO TELESCOPES

We present a study of requirements on the sensitivity of mm and sub millimeter wave receivers for application in radio astronomy. The study is based on the experience of the operation of the SIS receivers at the radio telescopes of IRAM and considers also the conditions of operation at the future radioastronomical instruments such as LSA. MMA and LMSA. Using a radio telescope and atmospheric model we consider the effect of the receiver sensitivity on the radio telescope operation in terms of observing time. The observing time at a radio telescope depends on the system noise temperature as strongly as on collecting area. which defines nearly all the cost of modern mm and sub mm instruments. As a compromise between the receiver development effort and the system performance we introduce a criterion of an "optimum" receiver noise. A strict requirement on the receiver operation is obtained. For an efficient use of the existing and the future radio telescopes. a 10 20 K SSB receiver noise in the mm band and 20-40 K SSB at sub millimeter wavelength are necessary. Finally the status of development of SIS receiver for mm and sum mm radio astronomy is presented.
Socio-demographic Factors Associated with Utilization of Breast and Cervical Cancer Screening Methods in Turkey

METHODS The data were used from the Turkey Health Survey conducted by Turkish Statistical Institute in 2014. We included 8606 women aged 25 and over in the study. The utilization of early screening methods (breast self-examination [BSE], mammography, or Pap smear [PS] test) was the dependent variable. Chi-square test was used to assess the association between sociodemographic factors and utilization of early screening methods.
Comparison of the convergence of two algorithms for adaptive FIR digital filters

The convergence properties of two different algorithms for the updating of the coefficients of an adaptive FIR digital filter are investigated and compared with one another. These algorithms are the stochastic iteration algorithm and the sign algorithm. In this latter algorithm a one-bit gradient estimation is used which makes its implementation very simple. The convergence is characterized by the residual echo variance after convergence, and a parameter that indicates the speed of the convergence. It is shown that the convergence of the sign algorithm can always be assured but is much slower than that of the stochastic iteration algorithm if the same variance of the residual echo is to be obtained.
