title: Exploring the Impact of Mentoring Relationships on the Development of Self-Initiated Expatriate Employees Working in China
Creators: name: Johnson-Tyas, Isaac
Publisher: name: University of Liverpool Repository

description: Purpose - The purpose of this thesis is to develop a greater understanding of how mentoring relationships exist between self-initiated expatriate (SIE) employees (employees who decided themselves to work and live abroad without a pre-determined timeline for returning to their home country) and how these relationships facilitate development. Mentoring relationships have been shown to have many positive benefits for employees, but the characteristics of mentoring relationships and the development benefits of these relationships between SIEs has not received much attention. This thesis contributes to this gap in the literature by elaborating on the characteristics of mentoring relationships and discussing their implications for development for Western SIEs working at a Chinese company in China. Methodology - A participatory action research (PAR) method is used in which participants and the researcher work together in the design, data collection, and data analysis. This was achieved through grouping six participants into three mentoring pairs and then exploring the mentoring experiences of the individuals, pairs, and group of participants during three PAR cycles. Data triangulation is achieved through collecting data from multiple sources including one-on-one interactions, observed pair interactions, and focus groups. Social exchange theory was used as a guiding theoretical model to understand mentoring relationships. Findings - The data has evidenced that three major themes characterize the mentoring relationships of self-initiated expatriate employees: communication, trust, and value. These themes were then discussed in terms of the benefits of mentoring which have previously been identified by researchers. These themes are also discussed in terms of social exchange theory which contributes to a more refined understanding of how mentoring relationships can be viewed as socially constructed cost-benefit exchanges involving varying perceptions of value. Implications for Practice - This thesis contributes to practice by highlighting the importance of communication, trust, and value in both the development of mentoring relationships between self-initiated expatriates and in facilitating professional development for SIEs. By emphasizing the identified themes and the creation of a mentoring program for SIEs, this thesis offers firms employing SIEs an important tool that can facilitate professional development. Future research is suggested to explore the professional development benefits of mentoring relationships between SIEs in different countries.

description: This is a scanned copy of a document of the enumeration of the Widdringtonia plot at Kleinplaas in Jonkershoek. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: Cocaine addiction is a chronic relapsing disorder that is difficult to treat in part because addicts relapse even after extended periods of abstinence. Given the importance of the mesolimbic dopamine (DA) system in drug addiction, we sought to characterize cocaine abstinence induced changes in rapid DA signaling in the nucleus accumbens (NAc). Here, rats were trained to self-administer cocaine for 14 consecutive days, then divided into two groups. Day 1 rats (D1; n = 7) underwent 24 hours of abstinence; Day 30 rats (D30; n = 7) underwent one month of abstinence. After abstinence, all rats underwent a single extinction session. Immediately after, rats were deeply anesthetized and fast scan cyclic voltammetry (FSCV) was used to measure DA release and uptake dynamics in the NAc core before and following a single cocaine injection. We show that one month of cocaine abstinence potentiates the peak concentration of electrically evoked DA in the NAc core following an acute injection of cocaine. This potentiation is not related to alterations in DA uptake parameters, which are unchanged following abstinence, but may reflect alterations in release. These results further support the abundance of literature showing that cocaine abstinence induces neuroplasticity in brain areas implicated in drug reward and relapse. The present findings also demonstrate critical differences between abstinence-induced neuroadaptations in DA signaling and those caused by drug exposure itself.

description: We study the polyharmonic problem $Δ^m u = \pm e^u$ in ${\mathbb R}^{2m}$, with $m \geq 2$. In particular, we prove that {\sl for any} $V > 0$, there exist radial solutions of $Δ^m u = -e^u$ such that $$\int_{{\mathbb R}^{2m}} e^u dx = V.$$ It implies that for $m$ odd, given arbitrary volume $V > 0$, there exist conformal metrics $g$ on ${\mathbb R}^{2m}$ with positive constant $Q$-curvature and vol$(g) =V$. This answers some open questions in Martinazzi's work.

description: Social deficits are a hallmark feature of autism spectrum disorder (ASD) and related developmental syndromes. Although there is no standard treatment for social dysfunction, clinical studies have identified oxytocin as a potential therapeutic with prosocial efficacy. We have previously reported that peripheral oxytocin treatment can increase sociability and ameliorate repetitive stereotypy in adolescent mice from the C58/J model of ASD-like behavior. In the present study, we determined that prosocial oxytocin effects were not limited to the adolescent period, since C58/J mice, tested in adulthood, demonstrated significant social preference up to 2 weeks following subchronic oxytocin treatment. Oxytocin was also evaluated in adult mice with underexpression of the N-methyl-D-aspartate receptor NR1 subunit (encoded by Grin1), a genetic model of autism- and schizophrenia- like behavior. Subchronic oxytocin had striking prosocial efficacy in male Grin1 knockdown mice; in contrast, chronic regimens with clozapine (66 mg/kg/day) or risperidone (2 mg/kg/day) failed to reverse deficits in sociability. Neither the subchronic oxytocin regimen, nor chronic treatment with clozapine or risperidone, reversed impaired prepulse inhibition in the Grin1 knockdown mice. Overall, these studies demonstrate oxytocin can enhance sociability in mouse models with divergent genotypes and behavioral profiles, adding to the evidence that this neurohormone could have therapeutic prosocial efficacy across a spectrum of developmental disorders.

description: As the societal implications of Artificial Intelligence (AI) continue to grow, the pursuit of responsible AI necessitates public engagement in its development and governance processes. This involvement is crucial for capturing diverse perspectives and promoting equitable practices and outcomes. We applied Cultural Consensus Theory (CCT) to a nationally representative survey dataset on various aspects of AI to discern beliefs and attitudes about responsible AI in the United States. Our results offer valuable insights by identifying shared and contrasting views on responsible AI. Furthermore, these findings serve as critical reference points for developers and policymakers, enabling them to more effectively consider individual variances and group-level cultural perspectives when making significant decisions and addressing the public's concerns.

description: We present an effective criterion to determine if a normal analytic compactification of C^2 with one irreducible curve at infinity is algebraic or not. As a by product we establish a correspondence between normal algebraic compactifications of C^2 with one irreducible curve at infinity and algebraic curves contained in C^2 with one place at infinity. Using our criterion we construct pairs of homeomorphic normal analytic surfaces with minimally elliptic singularities such that one of the surfaces is algebraic and the other is not. Our main technical tool is the sequence of "key forms" - a 'global' variant of the sequence of "key polynomials" introduced by MacLane to study valuations in the 'local' setting - which also extends the notion of "approximate roots" of polynomials considered by Abhyankar and Moh.

L’ambiente sonoro nella Firenze medicea tra spazio urbano e contesto cerimoniale. Il caso dei tornei alla sbarra (1579, 1589)

description: I due tornei alla sbarra qui trattati rientrano nelle manifestazioni festive allestite in occasione delle nozze medicee di Francesco I con Bianca Cappello (1579) e di Ferdinando I con Cristina di Lorena (1589). A partire da un eterogeneo corpus documentale di fonti, il presente contributo rilegge i due momenti festivi nel tentativo di ricostruire la presenza e il ruolo degli eventi sonori nella consuetudine della fonosfera storica urbana nella Firenze del XVI secolo. Secondo una impostazione motivata dalla relazione fra l’intero progetto sonoro e la comunità di spettatori-ascoltatori – non dunque prediligendo l’aspetto visuale che è senza dubbio quello preminente nell’allestimento di tali occasioni –, è stato possibile indagare nello spazio sonoro due dimensioni espressivo-formali della musica, quella di evento sonoro legato all’apparato effimero – dunque musica senza finalità artistiche – e quella della musica intesa quale atto esecutivo-performativo.

description: Mounting evidence indicates that ethanol (EtOH) exposure activates neuroimmune signaling. Alterations in pro-inflammatory cytokines after acute and chronic EtOH exposure have been heavily investigated. In contrast, little is known about the regulation of neurotransmission and/or modulation by anti-inflammatory cytokines in the brain after an acute EtOH exposure. Recent evidence suggests that interleukin-10 (IL-10), an anti-inflammatory cytokine, is upregulated during withdrawal from chronic EtOH exposure. In the present study, we show that IL-10 is increased early (1 h) after a single intoxicating dose of EtOH (5 g/kg, intragastric) in Sprague Dawley rats. We also show that IL-10 rapidly regulates GABAergic transmission in dentate gyrus neurons. In brain slice recordings, IL-10 application dose-dependently decreases miniature inhibitory postsynaptic current (mIPSC) area and frequency, and decreases the magnitude of the picrotoxin sensitive tonic current (Itonic), indicating both pre- and postsynaptic mechanisms. A PI3K inhibitor LY294002 (but not the negative control LY303511) ablated the inhibitory effects of IL-10 on mIPSC area and Itonic, but not on mIPSC frequency, indicating the involvement of PI3K in postsynaptic effects of IL-10 on GABAergic transmission. Lastly, we also identify a novel neurobehavioral regulation of EtOH sensitivity by IL-10, whereby IL-10 attenuates acute EtOH-induced hypnosis. These results suggest that EtOH causes an early release of IL-10 in the brain, which may contribute to neuronal hyperexcitability as well as disturbed sleep seen after binge exposure to EtOH. These results also identify IL-10 signaling as a potential therapeutic target in alcohol-use disorders and other CNS disorders where GABAergic transmission is altered.

Complexité et interprétation de la musique de Brian Ferneyhough: le travail de Caroline Delume sur le sixième mouvement de Kurze Schatten II

description: Sin dalla sua scoperta negli anni ’70, l’opera di Brian Ferneyhough è stata indissolubilmente legata alla nozione di complessità in musica, facendo del compositore inglese il leader di un nuovo movimento chiamato New Complexity. Mentre la ‘complessità’ della sua musica ha dato origine a una vasta letteratura, il rapporto tra l’esecutore e questa ‘complessità’, nonostante la sua ovvia importanza, non è mai stato affrontato in modo approfondito. Questo articolo analizza la scrittura ritmica di un movimento di Kurze Schatten II (1983-1989) per chitarra sola, anche attraverso gli schizzi d’autore, per poi descrivere i mezzi utilizzati dalla chitarrista Caroline Delume per comprendere questa scrittura. In questo modo, l’interazione dei due approcci riesce a far luce sulle questioni estetiche di tale ‘complessità’.

description: Atomic-scale magnetic nanostructures are promising candidates for future information processing devices. Utilizing external electric field to manipulate their magnetic properties is an especially thrilling project. Here, by careful identifying different contributions of each atomic orbital to the magnetic anisotropy energy (MAE) of the ferromagnetic metal films, we argue that it is possible to engineer both the MAE and the magnetic response to the electric field of atomic-scale magnetic nanostructures. Taking the iron monolayer as a matrix, we propose several interesting iron nanostructures with dramatically different magnetic properties. Such nanostructures could exhibit strong magnetoelectric effect. Our work may open a new avenue to the artificial design of electrically controlled magnetic devices.

description: This is a scanned copy of the population dynamics of Protea cynaroides and grandiceps in Hottentots Holland, Grabouw, site 3418BB/14. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: Social cognitive impairment is a key feature of schizophrenia and social cognition training (SCT) is a promising tool to address these deficits. Neurobiological dysfunction in schizophrenia has been widely researched, but neuronal changes induced by SCT have been scarcely explored. This review aims to assess the neuroplastic effects of SCT in patients with schizophrenia spectrum disorders. PubMed and Web of Science databases were searched for clinical trials testing the effects of SCT in functional and structural brain measurements of adult patients with schizophrenia or schizoaffective disorders. A total of 11 studies were included: five used fMRI, two used EEG and ERP, one used ERP only, two used MEG and one study used MRI. Data extracting and processing regarding sociodemographic and clinical variables, intervention characteristics, neuroimaging procedures, neuroplastic findings, effect sizes and study quality criteria was completed by two raters. Results indicate a wide range of structural and functional changes in numerous regions and circuits of the social brain, including early perceptual areas, the limbic system and prefrontal regions. Despite the small number of trials currently available, evidence suggests that SCT is associated with neuroplastic changes in the social brain and concomitant improvements in social cognitive performance. There is a lack of extensive knowledge about the neural mechanisms that underlie social cognitive enhancement after treatment, but the reported findings may shed light on the neural substrates of social cognitive impairment in schizophrenia and how improved treatment procedures can be developed and applied.
Performance e melodie nell’epica curda cantata: il caso di Beyta Dimdim nel Bahdinan (Iraq)

description: Questo lavoro è dedicato all’analisi degli aspetti sonori e performativi del beyt di Dimdim, epica della tradizione orale curda, effettuata a partire dai materiali raccolti durante una ricerca sul campo nel Bahdinan, Kurdistan iracheno. Il beyt è un importante genere narrativo affine al prosimetro e ha una valenza sociale importante come collettore della memoria storica popolare. L’azione performativa dei cantori, genericamente denominati dengbêj o beytbêj, comporta l’esecuzione a voce sola, l’uso di gestualità contenuta e poco teatralizzata e l’adozione di soluzioni testuali e melodiche diverse, pur attenendosi a un medesimo oicotipo. Offre poi particolare interesse la relazione tra la prosodia e la ritmica della dizione. La prima guidata da una versificazione formulare e da regole formali come l’uso costante della rima, la prevalenza di versi brevi (ottosillabi) e di sequenze rimiche, ovvero di una stroficità non regolare; l’altra controllata prevalentemente dagli schemi

description: Posttraumatic stress disorder (PTSD) is considered a disorder of recovery where individuals fail to learn and retain extinction of the traumatic fear response. In maltreated youth, PTSD is common, chronic, and associated with comorbidity. Studies of extinction-related structural volumes (amygdala, hippocampus, anterior cingulate cortex (ACC), and ventral medial prefrontal cortex (vmPFC)) and this stress diathesis, in maltreated youth were not previously investigated. In this cross-sectional study, neuroanatomical volumes associated with extinction in maltreated youth with PTSD (N=31), without PTSD (N=32), and in non-maltreated healthy volunteers (n=57) were examined using magnetic resonance imaging. Groups were sociodemographically similar. Participants underwent extensive assessments for strict inclusion/exclusion criteria and DSM-IV disorders. Maltreated youth with PTSD demonstrated decreased right vmPFC volumes compared with both maltreated youth without PTSD and non-maltreated controls. Maltreated youth without PTSD demonstrated larger left amygdala and right hippocampal volumes compared with maltreated youth with PTSD and non-maltreated control youth. PTSD symptoms inversely correlated with right and left hippocampal and left amygdala volumes. Confirmatory masked voxel base morphometry analyses demonstrated greater medial orbitofrontal cortex gray matter intensity in controls than maltreated youth with PTSD. Volumetric results were not influenced by psychopathology or maltreatment variables. We identified volumetric differences in extinction-related structures between maltreated youth with PTSD from those without PTSD. Alterations of the vmPFC may be one mechanism that mediates the pathway from PTSD to comorbidity. Further longitudinal work is needed to determine neurobiological factors related to chronic and persistent PTSD, and to PTSD resilience despite maltreatment.
