This narrative review considers the positive side of the work-family interface. It surveyed a range of relevant literature (1960–2012) using search terms on the positive work-family interface. From the literature it is evident that various concepts (e.g., work-family enhancement, work-family positive spillover, work-family facilitation and work-family enrichment) are used to conceptualise the positive side of the work-family interface. Further research is needed to explore the positive side of the work-family interface. Findings showed that only a few studies on the positive work-family interface phenomenon have been reported from the South African population, but there is still a huge gap in the South African literature regarding the positive work-family interface.  相似文献

Tempering of martensite in the absence of carbide precipitation leads to carbon partitioning into retained austenite. If the martensite/austenite interface is assumed to remain stationary during this process, the phase compositions reach a condition that has recently been called constrained carbon equilibrium. If iron atoms are sufficiently mobile at the interface, longer partitioning times may lead to migration of the ferrite/austenite interface. The interface may be expected to move in either direction, depending on the specific details of the phase fractions and compositions controlling the chemical potential of iron at the interface. If interface migration occurs during carbon partitioning, the situation is more complicated and conditions could exist where the interface moves first in one direction and then the other.  相似文献

An interface, controlled by a Z-80 central processor, that plugs into the PET microcomputer’s IEEE-488 port is described. This interface is capable of controlling 48 separate 28-V dc output signals, six of which are high current. Sixteen inputs (switch closures) can be accepted by the interface. Data tagged with real-time information are output automatically to cassette tape in PET format. This PET interface system is designed to accommodate a single experimental station.  相似文献

A system of FORTRAN-callable subroutines designed to facilitate running laboratories with the RSX operating system on a PDP-11 computer is presented. The subroutines include ones to give the FORTRAN programmer timing capability, better control of CRT input and output, control of a parallel-bit input and output interface, control of an analog-to-digital interface, and control of a digital-to-analog interface.  相似文献

Thirty-one first-year psychology graduate students in a computer applications course completed a set of structured problems, unstructured problems, and data-screening problems in each of two statistical computing environments: a menu-based interface (SPSS for Windows) and a traditional command-based interface (SPSSx). Performance on the menu-based interface was generally superior to performance on the command-based interface. More of the structured problems were completed successfully within the menu-based interface. The menu-based interface also facilitated error identification, was rated as easier to use, and was preferred nearly 4 to 1 over the command-based interface. For the unstructured problems, students identified more relationships in the data set and issued more statistical commands when working with the menu-based interface. These findings are consistent with the interpretation that because the menu-based interface requires fewer mental resources to be dedicated to the mechanics of analysis, more resources are available to devote to higher level problem solving.  相似文献

A general purpose input-output interface is an essential tool in many common research situations. This article describes a simple way to set up the IBM-compatible microcomputer’s RS-232 serial port as an interface with up to four inputs and two outputs. First, aspects of the serial port relevant to its use as an input-output interface are discussed. Next, port access commands needed to control output lines and monitor input lines in the appropriate way are described, and examples in the Turbo Pascal 5.0 language are provided. Finally, a schematic diagram and a discussion of a simple circuit to implement the interface are provided.  相似文献

Abstract

Chaki (1988) has recently proposed a model for diffusion-induced grain boundary migration (DIGM). In his Letter he concluded that the interface energy of a grain boundary and the free energy of mixing are responsible for DIGM and, from the equations he derived, it was claimed that they can explain many DIGM experimental results. However, on examining his model closely there appear to be some fundamental difficulties. The following are comments on his Letter:

(1) In Chaki's calculation of ΔGs he assumed that, after interface 1 had moved a distance δx, the radius of curvature of this interface increased from R to R + δx, which gives a surface energy drop of 2γVm δx/R2. However from many DIGM observations (for example Balluffi and Cahn (1981)) the curvature of a migrating boundary is increased rather then decreased, that is, the surface free- energy term actually prevents a grain boundary from migrating rather than helping it!

(2) Chaki considered ΔGcryst during the migration of interface 2. It is also necessary to consider AGcrys, during the migration of interface 1, since within the migration distance δx the structure is changed from a crystalline structure to a grain boundary core structure. ΔGm should also be considered during the migration of interface 2 since the concentration of the area swept by interface 2 will not be the same as that of a grain boundary core.  相似文献

We present an interface connecting the ACL2 theorem prover with external deduction tools. The ACL2 logic contains several mechanisms for proof structuring, which are important to the construction of industrial-scale proofs. The complexity induced by these mechanisms makes the design of the interface challenging. We discuss some of the challenges, and develop a precise specification of the requirements on the external tools for a sound connection with ACL2. We also develop constructs within ACL2 to enable the developers of external tools to satisfy our specifications. The interface is available with the ACL2 theorem prover starting from Version 3.2, and we describe several applications of the interface.  相似文献

Professional and scientific work will increasingly be conducted at computer workstations. An expert-system adaptive interface is one method for supporting learning and raising productivity of workstation activities. A prototype application for an adaptive interface is described in terms of machine intelligence, needs, design philosophy, and cognitive research. The intelligent interface prototype includes the operator’s psychometric profile, prior performance history, and a current keystroke performance stack within a conventional expert system. Productions in the form of conditionals between the operator’s keystrokes and three types of commands to the underlying software are described and illustrated. Commands entered, syntax errors, excessive repetition of keystrokes, and skill level are used to detect the user’s intentions and accordingly modify the display and command structure of the underlying software. Determining human intentions to produce machine adaptation to individual users is not a trivial task. Efforts to develop a powerful and general adaptive interface pose significant problems, and success cannot be assured without intensive cognitive research.  相似文献

While most small microcomputers are powerful enough to control intricate experiments, a major limitation of many is their limited I/O capability. An interface for the KIM-1 or similar small microcomputer is described that provides for up to 128 or more inputs. The basic components of the interface are a series of shift registers through which the incoming data are manipulated and read by the microcomputer. Provisions are also made to latch the incoming data, allowing detection of very high rates of or even simultaneous data input. The interface is modular in design and can be expanded by increments of eight inputs. Use of the system to monitor a large number of running wheels is discussed.  相似文献

The solid–liquid interface of metallic systems of small entropy of fusion is characterized by a rough interface and dendritic morphology. In contrast, systems of high entropy of fusion like semimetals and semiconductors show smooth interfaces and facetted interfaces. The present work demonstrates that, in an undercooled melt of a metal–metalloid alloy Ni2B of intermediate entropy of fusion, a transition from a rough to a smooth interface is induced by forced convection of the melt. Electrostatic levitation is used to container-less undercool droplets in a quiescent state with no convection while electromagnetic levitation (EML) is used to undercool droplets with forced convection. The growth velocity of the solid phase is monitored as a function of undercooling by a high-speed video camera. The data are analysed within dendrite growth theory. In the case of EML, a transition from a rough to a smooth interface is indicated during dendrite growth in the undercooled melt. This is confirmed by facetted microstructures of samples solidified upon undercooling by EML. Hopper-like crystals are formed like in non-metals as bismuth, halite and ice.  相似文献

Research investigating the relationship between family and work domains, according to a reductionist approach, has traditionally focused on the negative aspects of the work-family relationship. However, over the past 15 years a number of studies have also focused on the positive aspects of family and work relationships and on the interactions between the work-family interface and outcomes such as job and life satisfaction. These research studies have made it possible to capture different facets of the relationship between family and working life, and to clarify the specific nature of these interactions. In the present study, we tested a model that included positive and negative interactions between work and family as predictors of job and life satisfaction. We also examined the role of some of the potential moderators (work engagement, organizational and family support) of these relationships, using a sample of 427 Italian employees working in public administration. In our analysis, we first tested the factorial structure of the work-family interface measure (Kinnunen et al. Scandinavian Journal of Psychology, 47, 149–162 2006). Factor analysis confirmed a four-factor model: negative work-to-family interface, negative family-to-work interface, positive work-to-family interface, and positive family-to-work interface. Secondly, we analyzed the relationship between the work-family interface, job satisfaction and life satisfaction. Path analysis showed that the factors involved in the work-family interface influenced directly and indirectly life satisfaction, job satisfaction and work engagement. This analysis also showed that work engagement had a direct strong effect on job satisfaction and a direct weaker effect on life satisfaction. This pattern of findings is consistent with a causal sequence in which the work-family interface (WIF) and family-work interface (FIW) can increase or reduce a satisfaction-specific domain. Our results highlight the importance of using a theoretical and empirical model that integrates and focuses on both the positive and negative aspects of the work-family relationship. Moreover, this pattern demonstrates the potential consequences of this influence on employees’ working life and general well-being.  相似文献

In piezoelectric nanocomposites, surface/interface plays an important role in determining the size-dependent behavior of media. Within the framework of couple stress, the effect of surface/interface around a nano-hole on the anti-plane electro-mechanical behavior is examined. By introducing a surface/interface model, the stress and electric displacement effects on the size-dependent behavior are both considered. The governing equations in piezoelectric materials are decoupled into the classical ones. The displacement and electric potential are expressed by Bessel functions. By satisfying the boundary conditions around the hole with the interface/surface effect, the expanded coefficients are obtained. Through analysis, it is shown that the mechanical and electrical fields drastically depend on the relative size of the hole with respect to the characteristic length of the material. The effects of couple stresses on the stress and electric field are also addressed. Comparison with the existing results is also given.  相似文献

Blending phenomenological and evolutionary approaches, three studies explored the relationship between the body, the self, and disgust. Study 1 demonstrated that body parts that interface with the environment are sensed more than internal body parts, and are more intimately associated with the self. Studies 2 and 3, exploring the bodily distribution of disgust via organ transplantation scenarios, revealed that (a) transplantation of interface body parts is more disgusting than transplantation of internal parts; (b) others' interface parts elicit greater disgust than others' internal parts; and (c) individual differences in disgust sensitivity manifest primarily in reasoning about interface parts. The outer/inner dichotomy is a fundamental feature of the relationship between body and self, reflecting the adaptive utility of concentrating attention on the interface with the environment. Correspondingly, disgust, the emotion that protects the organism from contamination, is focused on the intersection between the body and the environment.  相似文献

Localised shear deformation of a material is usually identified as a particular feature of deformation inhomogeneity. Here, we show two different types of shear deformation-behaviour that occurred in Au–Cu multilayers subjected to microindentation load, namely, a cooperative-layer-buckling-induced shear banding in a nanoscale multilayer and a direct localised shearing across a layer interface along a shear plane in a submicron-scale multilayer. Theoretical analysis indicates that the formation of the two different types of shear deformation in the multilayers depends on a competition between the dislocation-pile-up-induced stress concentration at the layer interface and the barrier strength of the layer interface for glissile dislocation transmission.  相似文献

The NeXT computer system is a relatively new, inexpensive, 68040-based computer with high computational power, storage, graphics, audio, and other capabilities. The present article examines the effectiveness of the NeXT for studies of auditory sequential memory. In these studies, subjects track the time of occurrence of a sequence of tones, using a mouse that controls the position of sliders represented on the computer screen interface. This interface allows the subject to represent the different sounds on the y-axis and the time of their occurrence on the x-axis. The computer produces random orders of stimulus sequences, provides feedback, and stores and transforms accuracy and response time data from the slider positions for subsequent analysis. A tutorial for the development of this interface and its variations is provided. As well, procedures for programming the experiment and the operation of the interface are described, accompanied by a frank account of issues surrounding development and management. It is concluded that high-quality sound and ease of both graphics interface design and program modification make NeXT an attractive option for research on auditory sequential order, promising much for further applications as well. Successful use of the NeXT, however, demands much from technical personnel for both programming and system management.  相似文献

As computers become more prevalent as laboratory equipment, psychologists and graduate assistants will be more likely to be involved with interfacing the experiment to the computer. This paper presents some general ideas about the design and construction of digital computer interfaces and ways to facilitate their check-out and integration into the computer system. The suggestions center around the identification of functional modules within the interface or device from the beginning of the design process. These modules are preserved in the design and construction and are tested separately where possible. Specification of the interface signals between these functional units speeds debugging of a new device and facilitates maintenance of the device at a later date if adequately documented. It is important to ensure that these signals are readily available through test points and/or indicators. The paper suggests minimal equipment necessary to construct and debug an interface. It is suggested that an interactive construction procedure may be the most successful. The device is constructed in stages, with each part being verified as it is built, A simple interface is suggested for the beginner which gives him practice and a useful debugging aid as well.  相似文献
