A knowledge-intensity-based collaborative community governing mechanism for inter-organisational HR collaborations

PurposeStudies of inter-organisational relationships have mainly investigated collaborations in the technical domain. There is considerably less research conducted in the field of inter-organisational collaborations in the domain of human resource management (HRM). At the same time, it is acknowledged that inter-organisational collaboration in this domain is relevant for organisations. By focusing on inter-organisational HR collaborations, this study provides insights into how these collaborations are governed, as well as how the mode of governance is explained.Design/methodology/approachThe paper relies on a quantitative study among 161 Dutch companies that collaborate with each other on HR-related issues. A measure of governance of inter-organisational HR collaboration is developed and applied.FindingsOrganisations tend to apply a mixture of governance mechanisms to govern their inter-organisational HR collaborations. Hence, they apply a collaborative community type of governance to these HR collaborations. The analyses show that the level of knowledge intensity, in particular the extent to which the organisation applies organisational learning practices, explains the use of collaborative community.Originality/valueFirst, this study focuses on an under-researched field: inter-organisational HR collaborations. Secondly, the study extends existing insights into the governance of inter-organisational relationships by analysing a novel data set.
Respirable Aerosol Generation by Broiler Chickens

ABSTRACT RESPIRABLE aerosol particles in broiler chicken housing have been linked to increases in transfer of bird respiratory disease, reduced bird growth, and increased condemnation of meat at processing plants. Before respirable aerosols can be controlled, sources of aerosol generation must be identified and quantified. Two-, four-, and six-week old broiler chickens were placed in a clean room chamber on a wire floor and respirable and viable aerosol concentrations generated by the birds were monitored for 3-day periods. Air temperature and relative humidity were continuously monitored in the clean room in addition to aerosol concentrations. A logarithmic increase in respirable aerosol concentration (RAC) occurred as total weight of the birds increased. Mean concentrations of RAC for individual groups of birds ranged from 0.07 particles/mL for 2-week old birds to 2.48 particles/mL for 6-week old birds. Mean viable aerosol concentrations ranged from 0.04 to 23.0 particles/L. The largest concentration of respirable aerosol particles for all bird groups had diameters between 1.0 and 2.0 yim. Reduced bird activity during dark periods resulted in significantly lower RACs.
Use of nonlinear subgrade modulus in AASHTO design procedure

Resilient modulus ( M r ) of subgrade is a very important factor in the pavement design and evaluation process. Typically, this factor is evaluated using simple empirical (non–stress-dependent) relationships with CBR (California-bearing-ratio) values as defined by several agencies. However, with the current state of knowledge, it is evident that the response of typical unbound subgrade materials may be nonlinear and hence, a function of the state of stress. Because of this material's stress dependency, different pavement cross sections (due to change in layer thickness) and/or layer moduli will cause a change in the M r response of the subgrade material under given moisture-density conditions. Three approaches are presented in this paper to estimate the nonlinear resilient modulus response of fine grained soils to be used in the flexible design procedure from the American Association of State Highway and Transportation Officials (AASHTO). These approaches are based on stress-dependent Lotfi and Moossazade.
Infrastructure Impacts of Iowa's Renewable Energy

This paper investigates the physical and fiscal impacts of Iowa's existing biofuel plants and wind power industries. A four-county cluster in northern Iowa and a two-county cluster in southern Iowa were identified through a local agency survey as having a large number of diverse facilities and were selected for analysis of traffic and physical impact. The large-truck traffic patterns on Iowa's secondary and local roads from 2002 to 2008 were analyzed and associated with the pavement condition and county maintenance expenditures. A trend of increased maintenance costs in the year after a biofuel plant became operational as well as during the construction period was observed. Large-truck traffic also increased dramatically during the construction period and then dropped after the plant became operational, but not to the levels before the plant's construction. The major road damage associated with wind farms occurred during construction activities and predominantly on gravel roads. Face-to-face interviews with county engineers were conducted to validate the observed trends and discuss the limitations of the data. Finally, with an expanded sample of 24 counties, one-way panel data regression models were developed to estimate pavement condition and maintenance costs as a function of vehicle miles traveled, plant capacity and years of operation, corn and soybean production, and soil and environmental conditions.
The art of battery charging

The demand for portable products is showing exponential growth with no end in immediate sight. Along with the overall growth in volume has come increased demand for greater features and functions. This combination has brought the issue of power management to the forefront of engineering design considerations. The overall success of a portable product will not only be dictated by its features and functions, it will also be influenced by how long it can perform before running out of power, the time it takes to return the batteries to full capacity and the life expectancy of the battery. Sound engineering design begins with a good working knowledge of batteries and battery charging techniques.
Considerations for how to rate CPV

The concentrator photovoltaic (CPV) industry is introducing multiple products into the marketplace, but, as yet, the; community has not embraced a unified method for assessing a nameplate rating. The choices of whether to use 850,; 900, or 1000 W/m2 for the direct-normal irradiance and whether to link the rating to ambient or cell temperature will; affect how CPV modules are rated and compared with other technologies. This paper explores the qualitative and; quantitative ramifications of these choices using data from two multi-junction CPV modules and two flat-plate; modules.
Analysis of contract management processes at Fleet and Industrial Supply Centers (FISC) worldwide

Abstract : The purpose of this project is to assess the contracting process capabilities at Commander, Fleet, and Industrial Supply Centers (COMFISCS), which includes all seven Fleet and Industrial Supply Center (FISC) locations. These locations are Jacksonville, Florida; Norfolk, Virginia; Pearl Harbor, Hawaii; Puget Sound, Washington; San Diego, California; Sigonella, Italy; and Yokosuka, Japan. This analysis was conducted using the Contract Management Maturity Model (CMMM). The primary purpose of the study is to analyze FISC's contracting processes to identify key process-area strengths and weaknesses and to provide a road map for possible improvement, if needed. The study also focuses on the specific metrics currently used by COMFISCS to measure the performance of its contracting management processes. The results will provide COMFISCS and the individual FISC Commanders a snapshot of the maturity level of their contracting processes, both individually and as a whole. This will allow COMFISCS to identify the unique challenges that each individual FISC is facing and provide an assessment tool on how to effectively engage and overcome these challenges and potentially improve the organization's contracting processes.
Long non-coding RNA MAGI2-AS3 inactivates STAT3 pathway to inhibit prostate cancer cell proliferation via acting as a microRNA-424-5p sponge

Aberrant expression of long non-coding RNAs (lncRNAs) that results in sustained activation of cell growth promoting pathways is an important mechanism in driving prostate cancer progression. In the present study, we explored differentially expressed lncRNAs in two microarray datasets of prostate benign and malignant tissues. We found that MAGI2-AS3 was one of the most downregulated lncRNAs in prostate tumors, which was further confirmed in our collected clinical samples. The function assays showed that MAGI2-AS3 overexpression decreased cell viability and led to obvious cell apoptosis in PC-3 and DU145 prostate cancer cells. Elevation of MAGI2-AS3 decreased the activity of STAT3 in PC-3 and DU145. In addition, microRNA-424-5p (miR-424-5p), a positive regulator of STAT3 pathway, was predicted as a target of MAGI2-AS3, furthermore, the interaction between MAGI2-AS3 and miR-424-5p was confirmed via reverse-transcript polymerase chain reaction (RT-qPCR), dual luciferase reporter assay and RNA immunoprecipitation (RIP). MAGI2-AS3 upregulated miR-424-5p and downregulated COP1 in PC-3 and DU145. More importantly, IL6-induced activation of STAT3 pathway could attenuate the biological effect of MAGI2-AS3 in PC-3 and DU145. In clinical samples, MAGI2-AS3 levels were negatively correlated with miR-424-5p expression, while positively correlated with COP1 mRNA expression. Altogether, the current study revealed MAGI2-AS3 as a novel negative regulator of prostate cancer development.
Effect of Age on Strength of Unfired Soil Lime Bricks Containing Non Uniform Coconut Fibers

In some provinces in Indonesia, like West Java, fired clay and unfired soil lime bricks co-exist as non standard bricks. Low rise buildings and rural houses in Indonesia are often constructed with non-standard bricks. The paper discusses strength-time relation of unfired bricks reinforced with and without natural fibers. Untreated and treated coconut fibers with three different lengths (1 cm, 2.5 cm and 4 cm) were prepared for bricks reinforcements. The effects of 4% non-uniform fiber addition, which constitutes 1/3 part each of 1 cm, 2.5 cm and 4 cm average fiber length, was investigated. Absorption of the bricks was evaluated. For all type of bricks, up to 90 days compressive strengths are almost stable but bending strengths rapidly decrease with time. The results show that unfired bricks added with treated fiber resulted in better performances compared to those added with untreated fibers and without fibers.
Finite-Time Trajectory Tracking Control of Under-Actuated Autonomous Surface Vessels Based on Non-Singular Terminal Sliding Mode

Abstract In this paper, the trajectory tracking control problem of under-actuated autonomous surface vessels is investigated. Both the parameter uncertainties and environmental disturbances are considered in system dynamics. By combining a trajectory planning method and the non-singular terminal sliding mode control technique, two global finite-time stabilising controllers for position tracking, ie. the surge controller and the lateral motion controller, are proposed. In order to reduce the chattering, the boundary layer method with a novel saturation function is employed to derive two modified continuous controllers. Simulations demonstrate the effectiveness of the proposed control scheme.
Moisture Adsorption in Cereal Grain Technology – A Review With Emphasis on Rice

Effects of moisture adsorption on low-moisture rice were recognized as early as 1930. However, as rice production became mechanized, research emphasis changed to drying. Effects of moisture adsorption by low-moisture wheat grains were also observed. For the last 25 years, the moisture adsorption phenomenon has been gaining recognition and is rapidly becoming an area of primary research in post harvest rice technology.
Accurate statistical process variation analysis for 0.25-/spl mu/m CMOS with advanced TCAD methodology

Effects of statistical process variation on the 0.25-/spl mu/m CMOS performance have been accurately characterized by using a new calibrated TCAD methodology. To conduct the variation analysis, a series of TCAD simulations was conducted on the basis of DoE (design of experiments) with optimum variable transformations, which resulted in RSF's (response surface functions) for threshold voltage (V/sub th/) and saturation drain current (I/sub ds/). A new global calibration of the RSF model based on experimental data gives excellent accuracy within 0.02 V error in V/sub th/ and 3% error in I/sub ds/. Using calibrated RSF, statistical process variation effects on the device characteristics have been quantitatively evaluated for each process recipe. It is found that variation of the gate-oxide formation process shows the most significant effect on the NMOS /spl Delta/I/sub ds/ in the production process. Furthermore we have designed an optimized 0.25-/spl mu/m CMOS process and device on the basis of the RSF and also predicted the process variation effects on the device performance. It is shown that the V/sub th/ and I/sub ds/ variations of the 0.25-/spl mu/m CMOS exhibit less than 10% I/sub ds/ variation in the production level process, which is similar to the value of 0.35-/spl mu/m CMOS experimental data. Additional TCAD simulations for MOS model parameter generation of the 0.25-/spl mu/m device was also conducted to allow circuit-designers to use predictive worst case circuit design parameters before experimental chip fabrication.
The effect of structure, actuator, and sensor on the zeroes of controlled structures

Effects on the zero frequencies of single input single output systems of design and modelling decisions are explored. The pole-zero patterns of transfer functions from input to output are studied as a function of sensor and actuator choice, namely type and impedance, and location. A variety of zero definitions are used for the studies. Where possible infinite order models are adopted to explore the design decisions so that the effects of finite order modelling are removed. The design studies are parametric in nature, so that the effects of impedance and location may be better understood. Examples focus on point or localized actuators and sensors and simple uniform structures. The sensitivity of the zero frequencies to changes in the sensor and actuator location for both collocated and non-collocated cases are presented. Non-minimum phase behavior is visible in only certain non-collocated situations. In addition to the design decisions, the zeroes are shown to be a function of the modelling technique used to model the structural response for collocated and dual systems. Methods for improving the zero predictions in the control bandwidth are
Revisiting the Power to Forgive: A Dyadic Approach for Determining the Relations Between Power, Self-Esteem, and Forgiveness in Romantic Relationships

Power pervades interpersonal relationships and can impact relationship-related outcomes (e.g., forgiveness). Here, we expected a positive association between power and forgiveness in two studies involving German and Israeli couples (N = 149/174 couples). Actor–partner interdependence mediator models showed the expected positive associations of actor’s power with both actor’s forgiveness and partner’s forgiveness. Independent self-esteem partially mediated and interdependent self-esteem completely mediated the power–forgiveness link for actors. Also, high experienced power was associated with high self-esteem, which in turn was positively related to benevolence motivation and negatively related to revenge and avoidance motivation. The implications of these findings are relevant for couple’s therapy and advance our understanding of associations between power and relationship variables. Future research may distinguish between authentic and instrumental forgiveness and use experimental settings.
A rare case of drug‐induced bradycardia associated with the just low dose use of methylprednisolone in a child with COVID‐19

Methylprednisolone (MP) is usually used to reduce inflammation reaction and tissue damage, which may have a beneficial treatment effect on coronavirus disease 2019 (COVID‐19). However, we present the case of a child who manifests significant bradycardia with the use of just low dose MP on the premise of the long‐term use of arbidol. Arbidol can affect the activity of CYP3A4, which is also a key metabolic enzyme of MP by competitive inhibition, and which is easy to aggravate the side effects of MP. Therefore, more attention should be paid to bradycardia occurrence in the patient with COVID‐19 when MP is considered in COVID‐19.
The Application of Health and Safety Plan in Nigerian Construction Firms

Construction works all over the world pose serious threat to workers and even non-workers. Health and safety in Nigerian construction firms have long been an issue to reckon with due to the several reports of the occurrence of accidents during construction works. This study investigates the extent of application of Health and Safety Plan in construction firms in Nigeria. A purposive sampling technique was used purposely for convenience sake and data was fetched from three cities with equal representation by the aid of a structured questionnaire. Results reveal that even though most firms studied have been in business for over a decade, one quarter of them hardly comply with any Health and Safety Plan during construction. Furthermore, employees are assets but this study reveals that some firms fully in business neither have Health and Safety insurance for their employees nor do some facilitate payment of Health and Safety insurance for their staff. It was concluded that effective Health and Safety practices for employees in Nigeria are yet to be fully appreciated and implemented among construction firms. As such, it is recommended that relevant authorities should checkmate Health and Safety practices in the Nigerian construction industry.
Bifurcation Behavior of a Supercavitating Vehicle

In this effort, a numerical study of the bifurcation behavior of a supercavitating vehicle is conducted. The nonsmoothness of this system is due to the planing force acting on the vehicle. With a focus on dive-plane dynamics, bifurcations with respect to a quasi-static variation of the cavitation number are studied. The system is found to exhibit rich and complex dynamics including nonsmooth bifurcations such as the grazing bifurcation and smooth bifurcations such as Hopf bifurcations, cyclic-fold bifurcations, and period-doubling bifurcations, chaotic attractors, transient chaotic motions, and crises. The tailslap phenomenon of the supercavitating vehicle is identified as a consequence of the Hopf bifurcation followed by a grazing event. It is shown that the occurrence of these bifurcations can be delayed or triggered earlier by using dynamic linear feedback control aided by washout filters.Copyright © 2006 by ASME
A FURTHER ELABORATION AND EMPIRICAL EVALUATION OF THE OEHLEY PARTIAL TALENT MANAGEMENT COMPETENCY MODEL

South African organisations within both the private and public sectors of the economy are investing heavily into their talented employees, in an attempt to derive a sustainable competitive advantage. This competitive advantage is threatened when employees engage in turnover behaviours. This study is directed at understanding those factors that contribute to employees’ intention to quit following employees’ perceptions of training and development initiatives. Empirical support has been found that certain line management talent management competencies would result in the retention of talented employees. This study investigated an existing talent management competency structural model, with a specific focus on two talent management competencies related to employee development, namely: Talent Management Mindset and Develops Others. Furthermore, this study investigated the inclusion of additional latent variables (Organisational Trust, Perceived Organisational Support, and Felt Obligation) that may potentially explain additional variance in various organisational outcome variables (i.e. Job Satisfaction, Affective Commitment, Normative Commitment, and Intention to Quit). Through understanding how line managers’ competence on talent management competencies influence employees’ perceptions of organisational development initiatives and how these employee perceptions are causally related to Intention to Quit, organisations will be in the prime position to effectively address the issue of employee turnover, through structured talent management retention programmes. The results of the current study showed that the original structural model displayed good fit. Based on the modification index values calculated for the Γ and Β matrices, a number of modifications were made to the structural model. Following the modifications to the original model, the fit of the model improved, and support was derived for numerous causal relationships proposed in the model, whist others were not supported.

Generalized spectral-domain analysis for multilayered complex media and high-T/sub c/ superconductor applications

An efficient algorithm for rigorously deriving the spectral-domain impedance dyadic Green's function for MMICs on general complex anisotropic or bi-anisotropic substrates is developed. Its main advantage is that it provides closed-form expressions for transverse propagation constants and related immittances in the spectral domain and, therefore, allows the following parameters to be taken into account: dielectric and magnetic losses of anisotropic or bi-anisotropic media without restrictions to the magnitude of tensor elements, alternative directions for magnetic bias, and the finite metallization thickness of conventional conductors and/or superconductors including their losses. Microstrip and coplanar waveguide structures in open, shielded, and conductor-backed technology can be treated. The theory is verified by comparison with previously published data, and its flexibility is demonstrated for both superconductor and conventional conductor (M)MIC structures. >
