Principals’ experiences of being disempowered by union members

This study explored school principals’ experience of managing unionised schools in South Africa. Qualitative in-depth phenomenological interviews were conducted with a purposeful selected sample of 13 school principals of unionised schools (age range 36-60 years). The school principals responded to open-ended interviews on their managing of school business with staff labour union activity. Thematic coding was utilised to analyse the collected data. Findings indicate the school principals to experience managerial paralysis from adversarial and confrontational engagement by union leaders and members towards them. They reported union activity a significant task diversion through mob-mentality co-option of the membership preventing rational discourse and compromising work health and safety of all school community members. Avenues need to be explored for school staff unionisation to be a resource for the core business of child education.     

Authentic leadership influences on organisational commitment in a South African state hospital

This study investigated the influence of authentic leadership (AL) on employee organisational commitment (OC) in a South African state hospital. A convenience sample of 222 employees (female = 81%; black = 82%) completed the Authentic Leadership Questionnaire on their perceptions of AL behaviours among their leaders; namely self-awareness, relational transparency, internalised moral perspective, and balanced processing. The employees also completed the Organisational Commitment Questionnaire to self-report on their own OC; namely affective, continuance, and normative commitment. Data were analysed utilising regression analysis to predict employees’ self-reported OC from perceived AL behaviours. Findings suggest AL scores to predict OC scores as well as the OC dimensions of continuance and normative commitment. AL scores did not predict affective commitment. Employees whose leaders apply AL may be able to retain employees through increased OC.     

Can low-cost motion-tracking systems substitute a Polhemus system when researching social motor coordination in children?

Functionally stable and robust interpersonal motor coordination has been found to play an integral role in the effectiveness of social interactions. However, the motion-tracking equipment required to record and objectively measure the dynamic limb and body movements during social interaction has been very costly, cumbersome, and impractical within a non-clinical or non-laboratory setting. Here we examined whether three low-cost motion-tracking options (Microsoft Kinect skeletal tracking of either one limb or whole body and a video-based pixel change method) can be employed to investigate social motor coordination. Of particular interest was the degree to which these low-cost methods of motion tracking could be used to capture and index the coordination dynamics that occurred between a child and an experimenter for three simple social motor coordination tasks in comparison to a more expensive, laboratory-grade motion-tracking system (i.e., a Polhemus Latus system). Overall, the results demonstrated that these low-cost systems cannot substitute the Polhemus system in some tasks. However, the lower-cost Microsoft Kinect skeletal tracking and video pixel change methods were successfully able to index differences in social motor coordination in tasks that involved larger-scale, naturalistic whole body movements, which can be cumbersome and expensive to record with a Polhemus. However, we found the Kinect to be particularly vulnerable to occlusion and the pixel change method to movements that cross the video frame midline. Therefore, particular care needs to be taken in choosing the motion-tracking system that is best suited for the particular research.     

Children's reading of words, pseudohomophones, and other nonwords

In Experiment 1 children aged 8-9 and 9-10 years were tested for neighbourhood and pseudohomophone effects in nonword reading. Neighbourhood effects ( N effects) were robust irrespective of group or type of nonword. Pseudohomophones were read more accurately than other nonwords but this finding was robust only for the younger 8-9-year-olds. High-frequency words were read more accurately than low-frequency words, but the reverse applied to pseudohomophones based on high- and low-frequency words, although this was not robust. Error rates for the 9-10-year-olds in Experiment 1 were low, and so it was difficult to interpret the lack of a pseudohomophone advantage for reading nonwords in this age group. Experiment 2 was therefore carried out, which consisted of a replication of the first study with a further group of 9- 10-year-olds, but pronunciation latencies were measured, as well as accuracy. All the effects obtained in Experiment 1 were replicated but, in addition, an advantage for pseudohomophones in terms of pronunciation latencies was observed. The implications for accounts of reading development are discussed.     

Do Abrupt-onset Peripheral Cues Attract Attention Automatically?

The proportion of peripheral cues that predicted at which of two locations a discrimination target would occur was manipulated in three experiments. Near cues occurred adjacent to the target and far cues occurred adjacent to the other location. In Experiment 1, near and far cues were presented in separate blocks so each predicted target location. Both types of cue produced benefit relative to a neutral baseline. In Experiment 2 expectancy for near versus far cues was manipulated. In one group, 80% of the peripheral cues were near; in another, only 20% were near; in a third, near and far cues occurred randomly. Near cues always produced benefit. Far cues produced benefit when they were expected, had no effect in the random group, and sometimes produced cost when they were unexpected. Experiment 3 repeated the near-expected and far-expected conditions, but target duration was shortened to 50 msec. A similar pattern emerged, except that near cues produced less benefit at longer SOAs when they were unexpected. The data suggest that peripheral, abrupt-onset cues may produce benefit via an automatic process, but that such a process is more like location priming than the capture of attention. Expectancy determines whether and where attentional resources will be allocated in response to the cue.     

FROM PRIMARY MATERNAL PREOCCUPATION TO DEAD MOTHER*

Ferenczi (1929) writes about the unwelcome child who is not ushered into this world with care and grows up in the grip of the death instinct, with a depressive streak and a weakness in the capacity for life. Andre Green’s (1986) concept of the dead mother describes a similar phenomenon, by which the image of a loving mother is transformed into an inanimate, dead parent. The absent mother becomes the negative, which will then take up a central position in the child’s psyche. Winnicott (1956) describes a different maternal participation, and proposes that towards the end of her pregnancy the ordinary devoted mother develops a psychological condition which he calls primary maternal preoccupation, the main feature of which is the mother’s heightened attunement to her baby at the expense of all else. I suggest that there is a potent and clinically relevant connection among these concepts: a depressed or damaged mother can still provide temporary devotion before reverting back to a state of depressive absence and that, conversely, even the devoted mother will eventually recover from the state of primary maternal preoccupation and begin to tend to other matters, and the mother’s reclaiming herself can be traumatic for the child even under the best of circumstances. The connection among these concepts is illustrated with clinical material, including transference and countertransference implications, from the treatment of a young woman who grew up as an unwelcome child.

Reproductive Health CHOICES for Young Adults with Sickle Cell Disease or Trait: Randomized Controlled Trial Outcomes over Two Years

Interventions to assist reproductive health decision-making in populations affected by sickle cell disease (SCD) or trait (SCT) lack proven efficacy over time. Our aim was to compare effects of CHOICES, a Web-based multimedia education program on implementing informed reproductive plans, and usual care education (e-Book) on reproductive knowledge, intention, and behavior over 24 months. We randomized 234 participants with SCD (n?=?138) or SCT (n?=?96) (age 18–35 years, 35 % male, 94 % African American) to CHOICES and e-Book groups. Participants completed a sickle cell-specific reproductive measure before and four times after the intervention (6, 12, 18 and 24 months). Compared to the e-Book group the CHOICES group had significantly more improvement in knowledge over time (p?=?.004) but not intention (p?=?.18) or behavior (p?=?.69). At baseline, 114 (48.7 %) participants reported having partners who would not put the couple at risk for their children inheriting SCD. Of the 116 (49.6 %) at-risk participants, a higher poroportion of those who were in the CHOICES group chose partners that reduced their risk by the last visit than the e-Book group (p?=?.04). Study findings provide important insights for designing a national trial of the CHOICES intervention focusing on subjects whose partner status puts them at risk for having a child with SCD.
