On the Relationship Between Organizational Complexity and Organizational Structuration

This article represents a contribution to the conceptualization of organizational complexity. The first part of the article relates the concept of complexity to the production tasks of the organization by deriving measures of the complexity of production and planning tasks within the organization. This move allows us to analyze organizational activities in terms of the computational complexity of the tasks that the organization carries out. Drawing on concepts from theoretical computer science, the article introduces a taxonomy of production tasks based on their computational complexity and shows how to use the notion of computational complexity to analyze organizational phenomena such as vertical integration disintegration, the choice between markets and organizations as performers of particular production tasks, and the internal partitioning of organizational tasks and activities. The article then relates the complexity of the production function of the organization to the ways in which organizations structure themselves. It attempts to bring theorizing about organizational behavior based on complexity theory closer to the conceptual realm of "mainstream" organization theory and to make the concepts of complexity theory more useful to empirical examinations of firm dynamics and organizational behavior.
The neurobiology of non-suicidal self-injury (NSSI): a review

Non-suicidal self-injury (NSSI) is a relevant clinical problem with high prevalence rates in adolescence. Despite the high numbers of individuals with NSSI, the neurobiological background is still poorly understood. This review aims to present an overview from different fields of neurobiological research. Results from neuroimaging studies, as well as from studies on neurotransmitters, point to an insufficient stress response. Analgesia and hypalgesia are often reported from individuals with repetitive NSSI, supporting neurobiological alterations. Therefore NSSI can be understood as a coping strategy that serves to down-regulate high experienced emotions.

The value of student engagement for higher education quality assurance

As the principles and practices of quality assurance are further implanted in higher education, methodological questions about how to understand and manage quality become increasingly important. This paper argues that quality assurance determinations need to take account of how and to what extent students engage with activities that are likely to lead to productive learning. The idea of student engagement is introduced. A critical review of current possibilities for determining the quality of university education in Australia exposes limitations of quality assurance systems that fail to take account of student engagement. The review provides a basis for suggesting the broad relevance of student engagement to quality assurance. A sketch is provided of an approach for factoring student engagement data into quality assurance determinations.
Anomalous Southward Advection During 2002 in the Northern California Current: Evidence from Lagrangian Surface Drifters

Equatorward velocities in the upwelling jet of the northern California Current were 0.05–0.06 m s−1 faster in spring and summer 2002 than on average over 1998–2002. This result is based on a five‐year data set of surface drifters released across the continental margin off central Oregon (44.65°N) during April and July of each year. At this speed, anomalous water displacements of over a degree of latitude can occur in 20–25 days. Given a source of cold, Subarctic water to the north, this anomalous southward displacement is a plausible explanation for the cold, nutrient‐rich halocline water observed off Oregon during the summer of 2002. This interannual variability in the northern California Current and its implications for the ecosystem response, i.e., increased primary productivity, may be contrasted with interannual variability of the opposite sign ‐ increased poleward velocity, warmer temperatures and decreased productivity ‐ observed in this same region during El Niño years.
Effects of selective pressure block of Y-type optic nerve fibers on the receptive-field properties of neurons in the striate cortex of the cat

Abstract In an aseptic operation under surgical anesthesia, one optic nerve of a cat was exposed and subjected to pressure by means of a special cuff. The conduction of impulses through the pressurized region was monitored by means of electrodes which remained in the animal after the operation. The pressure was adjusted to selectively eliminate conduction in the largest fibers (Y-type) but not in the medium-size fibers (X-type). The conduction block is probably due to a demyelination and remains complete for about 3 weeks. Within 2 weeks after the pressure-block operation, recordings were made from single neurons in the striate cortex (area 17, area VI) of the cat anesthetized with N2O/O2 mixture supplemented by continuous intravenous infusion of barbiturate. Neurons were activated visually via the normal eye and via the eye with the pressure-blocked optic nerve (“Y-blocked eye”). Several properties of the receptive fields of single neurons in area 17 such as S (simple) or C (complex) type of receptive-field organization, size of discharge fields, orientation tuning, direction-selectivity indices, and end-zone inhibition appear to be unaffected by removal of the Y-type input. On the other hand, the peak discharge rates to stimuli presented via the Y-blocked eye were significantly lower than those to stimuli presented via the normal eye. As a result, the eye-dominance histogram was shifted markedly towards the normal eye implying that there is a significant excitatory Y-type input to area 17. In a substantial proportion of area 17 neurons, this input converges onto the cells which receive also non-Y-type inputs. In one respect, velocity sensitivity, removal of the Y input had a weak but significant effect. In particular, C (but not S) cells when activated via the normal eye responded optimally at slightly higher stimulus velocities than when activated via the Y-blocked eye. These results suggest that the Y input makes a distinct contribution to velocity sensitivity in area 17 but only in C-type neurons. Overall, our results lead us to the conclusion that the Y-type input to the striate cortex of the cat makes a significant contribution to the strength of the excitatory response of many neurons in this area. However, the contributions of Y-type input to the mechanism(s) underlying many of the receptive-field properties of neurons in this area are not distinguishable from those of the non-Y-type visual inputs.
Managerial (In)Attention to Competitive Threats

We integrate the Attention Based View of the firm and Regulatory Focus Theory to propose a model of managerial (in)attention that explains why appeals by middle managers for top managers to attend to specific threats of emerging rivals go unheeded. By acknowledging that different regulatory foci are elicited by different structural positions within the firm, we suggest that these differences in regulatory foci influence the allocation of attention to competitive intelligence warning of an emerging threat. We conclude by discussing how top managers might better evaluate whether threats of emerging rivals are worthy of deeper consideration.
Predictors of sources of self-confidence in collegiate athletes

The present study examined the antecedents of athletes' reliance on Vealey's nine sources of confidence. Achievement goal-orientation, perfectionism, coach-induced motivational climates were examined as predictors. Sources of confidence were categorized into controllable (e.g. mastery) and uncontrollable (e.g. situational favorableness) sources of confidence. Past research indicated that controllable sources of confidence are critical for enduring levels of confidence. Participants in the present study included 206 intercollegiate athletes. Path analysis showed that adaptive perfectionism positively predicted both controllable and uncontrollable sources of confidence, whereas maladaptive perfectionism positively only predicted uncontrollable sources of confidence. Ego-goal orientation and ego-involving motivational climate were not significant predictors; however, task-goal orientation and task-involving motivational climate were positive predictors of both categories of sources. Results implicate that nurturing adaptive perfectionistic characteristics, task-goal orientation, and task-involving motivational climate would be critical to athletes' selection of controllable sources of confidence.
Lay perspectives on hypertension and drug adherence: systematic review of qualitative research

Objective To synthesise the findings from individual qualitative studies on patients’ understanding and experiences of hypertension and drug taking; to investigate whether views differ internationally by culture or ethnic group and whether the research could inform interventions to improve adherence. Design Systematic review and narrative synthesis of qualitative research using the 2006 UK Economic and Social Research Council research methods programme guidance. Data sources Medline, Embase, the British Nursing Index, Social Policy and Practice, and PsycInfo from inception to October 2011. Study selection Qualitative interviews or focus groups among people with uncomplicated hypertension (studies principally in people with diabetes, established cardiovascular disease, or pregnancy related hypertension were excluded). Results 59 papers reporting on 53 qualitative studies were included in the synthesis. These studies came from 16 countries (United States, United Kingdom, Brazil, Sweden, Canada, New Zealand, Denmark, Finland, Ghana, Iran, Israel, Netherlands, South Korea, Spain, Tanzania, and Thailand). A large proportion of participants thought hypertension was principally caused by stress and produced symptoms, particularly headache, dizziness, and sweating. Participants widely intentionally reduced or stopped treatment without consulting their doctor. Participants commonly perceived that their blood pressure improved when symptoms abated or when they were not stressed, and that treatment was not needed at these times. Participants disliked treatment and its side effects and feared addiction. These findings were consistent across countries and ethnic groups. Participants also reported various external factors that prevented adherence, including being unable to find time to take the drugs or to see the doctor; having insufficient money to pay for treatment; the cost of appointments and healthy food; a lack of health insurance; and forgetfulness. Conclusions Non-adherence to hypertension treatment often resulted from patients’ understanding of the causes and effects of hypertension; particularly relying on the presence of stress or symptoms to determine if blood pressure was raised. These beliefs were remarkably similar across ethnic and geographical groups; calls for culturally specific education for individual ethnic groups may therefore not be justified. To improve adherence, clinicians and educational interventions must better understand and engage with patients’ ideas about causality, experiences of symptoms, and concerns about drug side effects.
Soft-Tissue Damage and Segmental Instability in Adult Patients With Cervical Spinal Cord Injury Without Major Bone Injury

Study Design. A retrospective imaging and clinical study. Objective. To evaluate the extraneural soft-tissue damage and its clinical relevance in patients with traumatic cervical spinal cord injury (SCI) without major bone injury. Summary of Background Data. To date, various kinds of cervical discoligamentous injuries have been demonstrated on magnetic resonance images in patients with SCI without bony injury. However, it has not been clear whether these magnetic resonance imaging abnormalities are actually related to spinal segmental instability and the patients' neurological status. Methods. Eighty-eight adult patients with acute traumatic cervical SCI without major bone injury were examined by flexion-extension lateral radiographs and magnetic resonance images within 2 days after trauma. We excluded patients with flexion recoil injury; therefore, most of the patients included were considered to have sustained a hyperextension injury. Instability of the injured cervical segment was defined when there was more than 3.5-mm posterior translation and/or more than a 11° difference in the intervertebral angle between the site of interest and adjacent segments. The neurological status was evaluated according to the American Spinal Injury Association motor score. Results. On magnetic resonance images, the damage to the anterior longitudinal ligament and intervertebral disc were apparent in 44 and 37 patients, respectively. Various degrees of prevertebral fluid collection (prevertebral hyperintensity) were demonstrated in 76 patients. These magnetic resonance imaging abnormalities were significantly associated with initial cervical segmental instability as judged by flexion-extension radiographs. Interestingly, the American Spinal Injury Association motor score had a significant association with either magnetic resonance imaging abnormalities or segmental instability but not with the cervical canal diameter. Conclusion. A considerable proportion of the patients with traumatic cervical SCI without major bone injury were shown to have various types of soft-tissue damage associated with cervical segmental instability at the early stages of the injury. The severity of paralysis greatly depended on these discoligamentous injuries.
Emergent Change and its Implications for Professional Autonomy and Managerial Control: A Case Study from Midwifery

Change can be seen as inevitable and constant, unpredictable and sometimes alarming and yet to stand still risks decay and stagnation. All organizations therefore need to be able to change and adapt to internal and external forces. The ability of the individual to embrace such change is in part due to the way change is managed, with this management approach often a reflection of the institution's culture whether it is in the private or public sector. Using a case study from midwifery, this article explores the tensions found between professional autonomy and managerial control during the application of a Scottish practice change initiative by NHS QIS Scotland in the repair of perineal trauma following childbirth. The study found a number of inter-related factors that drive the effectiveness of clinical change implementation namely; the emphasis placed on evidence-based practice, the role played by communities of practice within the hospital culture, the level of management commitment, and the personal and positional characteristics of the ‘change agents’. Two different stories of the change process emerged: one planned, staged and linear; the other continuous, dynamic and unpredictable.
Preliminary evidence for the proposed relationship between frequent nightmares and schizotypal symptomatology

The relationship between several measures of schizotypic signs and the reported frequency of nightmares was evaluated in a college student population. A significant positive relationship to nightmare frequency was found for three of the four schizotypy measures (perceptual aberration, intense ambivalence, and somatic symptoms). The observed relationships appeared to be stronger for women than for men. There was a negative relationship between physical anhedonia and nightmare frequency. The results are discussed within the context of object relations theory utilizing an ego boundary model and are consistent with previous research independently implicating boundary impairment in the etiology of both phenomena.
The Translation of Transnational Voluntary Standards into Practices: Civil Society and the Forest Stewardship Council in Russia

The article analyses closely the role of civil society in the local translation and adaptation of transnational standards of responsible use of natural resources in global certification regimes. The study builds on original evidence from Russia on civil society and forest certification, based on extensive fieldwork. It argues that the local translation of global sustainability standards into on-the-ground practices is not a straightforward execution of rules imposed by powerful transnational actors—e.g. international nongovernmental organizations, multinationals, governments, or consumers. Rather, local civil society actors elaborate the ways in which transnational standards are implemented locally and thereby construct new knowledge related to standard implementation and responsible natural resource management. The paper contributes to the literature on transnational governance by examining the involvement of civil society organizations in the translation, adaptation, and learning dynamics in global certification regimes.
Conceptualizing the EU’s Social Constituency

The EU is often considered to be a unique entity. This assertion rests on assessments of its institutional character more than on assessments of its social constituency, i.e., the structure of demands and expectations that citizens and groups place on the EU. Establishing the character of the latter is important both to understand the EU as polity and to understand its democratic deficit. It is also of theoretical interest given the increased focus on recognition politics, not only within nation-states but also within the transnational realm. This article develops a conceptual-methodological framework with a set of structured tests so as to permit us to establish the character of the EU’s social constituency. This framework combines a philosophical approach to recognition with a sociological approach to contentious politics. A central element is the notion of ‘recognition order’, and the article briefly examines whether the EU might be said to make up a unique recognition order.
Embryonic and Early Fetal Development of the Human Neocortex

Early corticogenesis was studied in human embryos and early fetuses from Carnegie stages 16 to 22 (5–8 gestational weeks) by using immunohistochemistry for Reelin (Reln), calretinin (CR), and glutamic acid decarboxylase (GAD). A first population of Reln-positive cells appears in the neocortical anlage at stage 16 and increases in number at stages 17–18. At stages 19–20, a monolayer of horizontal CR- and GAD-positive, Reln-negative neurons forms in the preplate, whereas Reln-positive cells shift into a subpial position. Another cell class, the pioneer projection neuron, is CR-positive but GAD- and Reln-negative; pioneer cells contribute early corticofugal axons. Pioneer cells first appear below the monolayer at stage 20 and form a pioneer plate at stage 21. The cortical plate (CP) proper emerges at stage 21 and inserts itself within the pioneer plate, which is thus split into a minor superficial component and a larger deep component that presumably corresponds to the subplate. Initial CP neurons are radially organized and mostly CR-negative. Reln-positive cells remain consistently segregated from the pioneer cells and are thus not directly involved in preplate partition. Our data indicate that the neuronal composition of the human neocortical preplate is more complex than generally described and that various neurons participate in a sequence of events that precede the emergence of the CP.
Late-L2 increased reliance on L1 neurocognitive substrates: A comment on Babcock, Stowe, Maloof, Brovetto & Ullman (2012)

Babcok et al. (2012) claim that Paradis (1994, 2004, 2009) argues that the reliance of late L2 learners on L1 neurocognitive mechanisms increases over time across both lexical and grammatical functions, namely for lexical items as well as rule-governed grammatical procedures, when in fact one can find repeated statements to the contrary in the very publications cited by the authors. Actually, Paradis’ main contention over the past 20 years has been that, contrary to grammatical functions, lexical items (as meaning–form relationships) are always of the same nature in L1 and L2 (hence stored declaratively). Thus in L2, only the neurocognitive mechanisms on which aspects of the grammar depend change over time. Consequently, the finding that length of residence (like age of arrival) influences the mechanisms underlying regular (composed), but not irregular (stored) verb forms, is compatible with Paradis’ views, in contradiction to what Babcock et al. are also suggesting.
The psychosocial spiritual experience of elderly individuals recovering from stroke: a systematic review

Objectives The objective of this review was to appraise and synthesise best available evidence on the psychosocial spiritual experience of elderly individuals recovering from stroke. Inclusion criteria This review considered qualitative studies whose participants were adults, mean age of 65 years and older, and who had experienced a minimum of one stroke. Studies were included that described the participant's own experience of recovering from stroke. Search strategy The search strategy sought to find both published and unpublished studies and papers, not limited to the English language. An initial limited search of MEDLINE and CINAHL was undertaken followed by an analysis of text words contained in the title and abstract, and of index terms used to describe the article. A second extensive search was then undertaken using all identified key words and index terms. Methodological quality Each paper was assessed by two independent reviewers for methodological quality prior to inclusion in the review using the Qualitative Assessment and Review Instrument (QARI) developed by the Joanna Briggs Institute. Disagreements were resolved through consultation with a third reviewer. Data collection Information was extracted from each paper independently by two reviewers using the data extraction tool from QARI developed by the Joanna Briggs Institute. Disagreements were resolved through consultation with a third reviewer. Data synthesis Data synthesis aimed to portray an accurate interpretation and synthesis of concepts arising from the selected population's experience during their recovery from stroke. Results A total of 35 studies were identified and of those 27 studies were included in the review. These qualitative studies examined the perceptions of elderly individuals who had experienced a stroke. Findings were analysed using JBI‐QARI. The process of meta‐synthesis using this program involved categorising findings and developing synthesised topics from the categories. Four syntheses were developed related to the perceptions and experiences of stroke survivors: sudden unexpected event, connectedness, reconstruction of life and life‐altering event. Conclusion The onset and early period following a stroke is a confusing and terrifying experience. The period of recovery involves considerable psychological and physical work for elderly individuals to reconstruct their lives. For those with a spiritual tradition, connectedness to others and spiritual connection is important during recovery. The experience of stroke is a life‐altering one for most elderly individuals, involving profound changes in functioning and sense of self.
