This study investigated the use of flexitime as a Work-life balance (WLB) policy and understanding employee perceptions regarding the use of flexitime among South African employees. A qualitative design with an exploratory approach was used. A non-probability purposive sample (n = 15) was taken in the financial sector. Data collection was done by was means of semi-structured interviews. Content analysis was used to analyse the data. Four main themes were extracted. The first two themes related to the various ways in which participants use flexitime and the influencing factors. Participants use flexitime according to their own preference (e.g., Spillover of working hours, dividing one's working day into smaller work hours, working from different locations) and were influenced by factors such as client's needs and expectations, own workload/pressure and personal commitments/responsibilities. The third theme related to various perceptions regarding the level of position of management, visibility and also personal life and situation. The last theme indicated that the use of flexitime have consequences, which include amongst others delay in work/deadlines, reduced productivity or performance, increased workload and health consequences.  相似文献

A hallmark of the human language faculty is the use of syntactic rules. The natural vocalizations of animals are syntactically simple, but several studies indicate that animals can detect and discriminate more complex structures in acoustic stimuli. However, how they discriminate such structures is often not clear. Using an artificial grammar learning paradigm, zebra finches were tested in a Go/No-go experiment for their ability to distinguish structurally different three-element sound sequences. In Experiment 1, zebra finches learned to discriminate ABA and BAB from ABB, AAB, BBA, and ABB sequences. Tests with probe sounds consisting of four elements suggested that the discrimination was based on attending to the presence or absence of repeated A- and B-elements. One bird generalized the discrimination to a new element type. In Experiment 2, we continued the training by adding four-element songs following a ‘first and last identical versus different’ rule that could not be solved by attending to repetitions. Only two out of five birds learned the overall discrimination. Testing with novel probes demonstrated that discrimination was not based on using the ‘first and last identical’ rule, but on attending to the presence or absence of the individual training stimuli. The two birds differed in the strategies used. Our results thus demonstrate only a limited degree of abstract rule learning but highlight the need for extensive and critical probe testing to examine the rules that animals (and humans) use to solve artificial grammar learning tasks. They also underline that rule learning strategies may differ between individuals.  相似文献

A substantial amount of empirical and theoretical debate remains concerning the extent to which an ability to orient with respect to the environment is determined by global (i.e., principal axis of space), local (i.e., wall lengths, angles), and/or view-based (i.e., stored representation) accounts. We developed an orientation task that allowed the manipulation of the reliability of the principal axis of space (i.e., searching at the egocentric left- and/or right-hand side of the principal axis) between groups while maintaining goal distance from the principal axis, local cues specifying the goal location (i.e., short wall left, short wall right, and obtuse angle), and visual aspects of the goal location consistent across groups. Control and test trials revealed that participants trained with a reliable principal axis of space utilized both global and local geometric cues, whereas those trained with an unreliable principal axis of space utilized only local geometric cues. Results suggest that both global and local geometric cues are utilized for reorientation and that the reliability of the principal axis of an enclosure differentially influences the use of geometric cues. Such results have implications for purely global-based, purely local-based, and purely view-based matching theoretical accounts of geometry learning and provide evidence for a unified orientation process.  相似文献

This study proposes to apply the paradigm of Churchill in the case of the adaptation in french and validation of the Maignan and Ferrell scale (1999) based on the model developed by Carroll (1979). This model proposes to distinguish four principles of social responsibility: economic, legal, ethical and philanthropic responsibility. Four factors were highlighted in a first exploratory study conducted among 320 workers. This structure was confirmed during a second confirmatory investigation among 287others workers. If the four identified factors do not match exactly to the theoretical chosen model, they bring value to support the differences in social responsibility between the internal actors and external actors.  相似文献

Despite their widespread use, many self‐report mood scales have very limited normative data. To rectify this, Crawford et al. have recently provided percentile norms for a series of self‐report scales. The present study aimed to extend the work of Crawford et al. by providing percentile norms for additional mood scales based on samples drawn from the general Australian adult population. Participants completed a series of self‐report mood scales. The resultant normative data were incorporated into a computer programme that provides point and interval estimates of the percentile ranks corresponding to raw scores for each of the scales. The programme can be used to obtain point and interval estimates of the percentile ranks of an individual's raw scores on the Beck Anxiety Inventory, the Beck Depression Inventory, the Carroll Rating Scale for Depression, the Centre for Epidemiological Studies Rating Scale for Depression, the Depression, Anxiety, and Stress Scales (DASS), the short‐form version of the DASS (DASS‐21), the Self‐rating Scale for Anxiety, the Self‐rating Scale for Depression, the State–Trait Anxiety Inventory (STAI), form X, and the STAI, form Y, based on normative sample sizes ranging from 497 to 769. The interval estimates can be obtained using either classical or Bayesian methods as preferred. The programme (which can be downloaded at http://www.abdn.ac.uk/~psy086/dept/MoodScore_Aus.htm ) provides a convenient and reliable means of obtaining the percentile ranks of individuals' raw scores on self‐report mood scales.  相似文献

The development of speech language therapy students into clinicians is an area of increasing interest as educators focus on how knowledge, skills and attitudes are taught and learnt within the profession. The personal journeys of students through experiences of service learning have potential to further our understanding of the impact of civic engagement on the student experience and their learning. This paper explores the journeys of first year speech and language therapy students through a Thematic Analysis of reflective letters written by students to themselves at the beginning and completion of a service learning module. Analysis demonstrates development of interpersonal and preclinical skills as well as an understanding of attitudes and values inherent in the social model of disability. The skills and attitudes developed by the students through participation in the Conversation Partner Scheme are consistent with social model principles that support therapists to fully address the long-term, real life needs of clients with aphasia (the acquired communication disorder that frequently follows stroke). The interface between the social model of disability and the role of service learning in nurturing the attitudes and values which underpin this model are explored.  相似文献

The author attempts to understand the underpinnings of a ruminative depression that occurred in a patient after a troubled first analysis. Negative therapeutic reaction is often assumed to be the result of a patient's unconscious guilt or masochism and thus an intrapsychic phenomenon, but the author asserts that iatrogenic phenomena in the form of persistent misunderstandings and enactments that remain unanalyzed contribute to a destructive treatment experience. The analysand may relive the failed treatment again and again in his or her mind in an attempt to resolve it. The author asserts that a traumatic treatment experience can foster depressive rumination.  相似文献

When listening to speech in everyday-life situations, our cognitive system must often cope with signal instabilities such as sudden breaks, mispronunciations, interfering noises or reverberations potentially causing disruptions at the acoustic/phonetic interface and preventing efficient lexical access and semantic integration. The physiological mechanisms allowing listeners to react instantaneously to such fast and unexpected perturbations in order to maintain intelligibility of the delivered message are still partly unknown. The present electroencephalography (EEG) study aimed at investigating the cortical responses to real-time detection of a sudden acoustic/phonetic change occurring in connected speech and how these mechanisms interfere with semantic integration. Participants listened to sentences in which final words could contain signal reversals along the temporal dimension (time-reversed speech) of varying durations and could have either a low- or high-cloze probability within sentence context. Results revealed that early detection of the acoustic/phonetic change elicited a fronto-central negativity shortly after the onset of the manipulation that matched the spatio-temporal features of the Mismatch Negativity (MMN) recorded in the same participants during an oddball paradigm. Time reversal also affected late event-related potentials (ERPs) reflecting semantic expectancies (N400) differently when words were predictable or not from the sentence context. These findings are discussed in the context of brain signatures to transient acoustic/phonetic variations in speech. They contribute to a better understanding of natural speech comprehension as they show that acoustic/phonetic information and semantic knowledge strongly interact under adverse conditions.  相似文献
