The H1P1 family of cytoskeletal-associated proteins
Creators: name: Chopra, Vikramjit
Publisher: name: University of British Columbia
Year: 2009

description: Huntingtin-interacting protein 1 (HJPT) is a membrane associated protein which interacts with huntingtin, the protein altered in Huntington Disease (HD). It was determined that the H1P1 gene consists of 32 exons spanning approximately 215 kb of genomic DNA and gives rise to two alternate splice forms termed HIPl-1 and HIP1- 2. Additionally, a novel homolog of HIP1, termed HIP12, was identified. HIP1 and HIP12 share significant amino acid identity and both proteins contain an epsin N-terminal homology (ENTH), coiled coil and talin-like domains. While overexpression of HTP1 is toxic in cell culture, HIP12 did not confer toxicity in the same assay systems. Interestingly, HIP12 did not interact with huntingtin but was able to interact with HJPT suggesting a potential interaction in vivo which may influence the function of each respective protein. Tissue distribution studies indicated that HIP1 was expressed predominantly within the brain whereas HIP12 expression was more ubiquitous. Within cells, HIP1 and HJPT2 displayed a similar punctate distribution at the plasma membrane and underlying cortical actin cytoskeleton. HIP1 was shown to interact with the endocytic proteins clathrin heavy chain and AP2. However, HIP12 displayed weak binding to clathrin heavy chain and no interaction with AP2. HIP1 and HIP12 were also shown to interact with the clathrin light chain. In addition, it was also revealed that HJPT and HIP12 were capable of inducing the assembly of the clathrin coat in vitro. Finally, it was determined that HIP12 interacts with F-actin suggesting that HIP12 may interact with the cortical actin cytoskeleton underlying clathrin-coated pits and vesicles. HIP1 may be indirectly associated with the actin cytoskeleton by forming heterodimers with HIP12. Thus, HTP1 and HTP12 may act as a molecular "link" between the endocytic machinery and the cortical actin cytoskeleton. Taken together, these results demonstrate that HIP1 and HIP12 are components of the endocytic machinery that participate in the recruitment, assembly and stabilization of the clathrin lattice structure. The observation that huntingtin associates with HIP1 suggests that it may function in endocytosis and transport. Since mutant huntingtin displays an altered interaction with HIP1, it raises the possibility that HD may be the result of defects in endocytosis and transport. The determination of the cellular functions of the HJP1 family and huntingtin in endocytosis and transport may provide valuable insights into the pathogenic mechanism(s) underlying HD.

description: The Einstein-Gauss-Bonnet equations projected from the bulk to brane lead to a complicated Friedmann equation which simplifies to $H^2 \sim ρ^q$ in the asymptotic regimes. The Randall-Sundrum (RS) scenario corresponds to $q=2$ whereas $q=2/3$ $&$ $q=1$ give rise to high energy Gauss-Bonnet (GB) regime and the standard GR respectively. Amazingly, while evolving from RS regime to high energy GB limit, one passes through a GR like region which has important implications for brane world inflation. For tachyon GB inflation with potentials $V(ϕ) \sim ϕ^p$ investigated in this paper, the scalar to tensor ratio of perturbations $R$ is maximum around the RS region and is generally suppressed in the high energy regime for the positive values of $p$. The ratio is very low for $p>0$ at all energy scales relative to GB inflation with ordinary scalar field. The models based upon tachyon inflation with polynomial type of potentials with generic positive values of $p$ turn out to be in the $1 σ$ observational contour bound at all energy scales varying from GR to high energy GB limit. The spectral index $n_S$ improves for the lower values of $p$ and approaches its scale invariant limit for $p=-2$ in the high energy GB regime. The ratio $R$ also remains small for large negative values of $p$, however, difference arises for models close to scale invariance limit. In this case, the tensor to scale ratio is large in the GB regime whereas it is suppressed in the intermediate region between RS and GB. Within the frame work of patch cosmologies governed by $H^2 \sim ρ^q$, the behavior of ordinary scalar field near cosmological singularity and the nature of scaling solutions are distinguished for the values of $q < 1$ and $q > 1$.

Impact and biological control of Lythrum salicaria in southwestern British Columbia
Creators: name: Denoth, Madlen
Publisher: name: University of British Columbia
Year: 2009

description: Purple loosestrife, Lythrum salicaria, is a Eurasian plant that has invaded North American wetlands over the last 200 years. As a precautionary measure, but without detailed knowledge of the ecological impact of Lythrum on native species, a biological control project was started in the 1990s with the introduction of Galerucella calmariensis, a leaf-feeding beetle of European origin. To measure the ecological impact of Lythrum, I assessed the effect of Lythrum on a rare, native plant species, Sidalcea hendersonii. To evaluate the biological success of the biological control project, I investigated the effectiveness of the biological control agent and identified factors associated with among-site variability in defoliation levels. Lythrum's impact on Sidalcea was not stronger than the impact of native species, possibly owing to the early emergence in the spring and the tall growth of Sidalcea. The abundance of Lythrum in a marsh where it co-occurs with Sidalcea did not increase significantly from 1979 to 1999, which suggests that the invasion process was largely completed by 1979. The effectiveness of the control agent was dependent on site condition. In tidal areas, the beetles could not establish due to the tidal disturbances. At sites where the control agent established, the reproductive performance and dry biomass of Lythrum were strongly reduced by beetle feeding damage in the same year, but stem density only declined at one site, Chilliwack, after severe herbivory over a four-year period. At most other non-tidal sites, plant stem density increased, and stem density changes were inversely related to the average beetle feeding damage during the previous four years. Beetle feeding damage was associated with predation on G. calmariensis eggs, but not predation on any other life-history stage, or plant quality. The densities of crawling, invertebrate predators were not generally related to predation levels, suggesting that predation did not vary in response to predator abundance, but to predator attack levels. I discuss the level of success of this biological control project and the need for control methods in tidal areas.

description: The observation of a compact object with a mass of $2.50-2.67M_{\odot}$ on August 14, 2019, by the LIGO Scientific and Virgo collaborations (LVC) has the potential to improve our understanding of the supranuclear equation of state. While the gravitational-wave analysis of the LVC suggests that GW190814 likely was a binary black hole system, the secondary component could also have been the heaviest neutron star observed to date. We use our previously derived nuclear-physics-multimessenger astrophysics framework to address the nature of this object. Based on our findings, we determine GW190814 to be a binary black hole merger with a probability of $>99.9\%$. Even if we weaken previously employed constraints on the maximum mass of neutron stars, the probability of a binary black hole origin is still $\sim 81\%$. Furthermore, we study the impact that this observation has on our understanding of the nuclear equation of state by analyzing the allowed region in the mass-radius diagram of neutron stars for both a binary black hole or neutron star--black hole scenario. We find that the unlikely scenario in which the secondary object was a neutron star requires rather stiff equations of state with a maximum speed of sound $c_s\geq \sqrt{0.6}$ times the speed of light, while the binary black hole scenario does not offer any new insight.

title: Interaction Forests: Identifying and exploiting interpretable quantitative and qualitative interaction effects

Year: 2021

description: Although interaction effects can be exploited to improve predictions and allow for valuable insights into covariate interplay, they are given little attention in analysis. We introduce interaction forests, which are a variant of random forests for categorical, continuous, and survival outcomes, explicitly considering quantitative and qualitative interaction effects in bivariable splits performed by the trees constituting the forests. The new effect importance measure (EIM) associated with interaction forests allows ranking of the covariate pairs with respect to their interaction effects' importance for prediction. Using EIM, separate importance value lists for univariable effects, quantitative interaction effects, and qualitative interaction effects are obtained. In the spirit of interpretable machine learning, the bivariable split types of interaction forests target well interpretable interaction effects that are easy to communicate. To learn about the nature of the interplay between identified interacting covariate pairs it is convenient to visualise their estimated bivariable influence. We provide functions that perform this task in the R package diversityForest that implements interaction forests. In a large-scale empirical study using 220 data sets, interaction forests tended to deliver better predictions than conventional random forests and competing random forest variants that use multivariable splitting. In a simulation study, EIM delivered considerably better rankings for the relevant quantitative and qualitative interaction effects than competing approaches. These results indicate that interaction forests are suitable tools for the challenging task of identifying and making use of well interpretable interaction effects in predictive modelling.

description: Nanomagnets form the building blocks for a gamut of miniaturized energy-efficient devices including data storage, memory, wave-based computing, sensors and biomedical devices. They also offer a span of exotic phenomena and stern challenges. The progress in the magnetization dynamics of single nanomagnets and one- and two-dimensional arrays of nanostructures in the form of dots, antidots, nanoparticles, binary and bicomponent structures and patterned multilayers have been presented. Progress in unconventional and new structures like artificial spin ice and three-dimensional nanomagnets and spin textures like domain walls, vortex and skyrmions have been presented. Furthermore, a huge variety of new topics in the magnetization dynamics of magnetic nanostructures are rapidly emerging. An overview of the steadily evolving topics like spatio-temporal imaging of fast dynamics of nanostructures, dynamics of spin textures, artificial spin ice have been discussed. In addition, dynamics of contemporary and newly transpired magnetic architectures such as nanomagnet arrays with complex basis and symmetry, magnonic quasicrystals, fractals, defect structures, novel three-dimensional structures have been introduced. Effects of various spin-orbit coupling and ensuing spin textures as well as quantum hybrid systems comprising of magnon-photon, magnon-phonon and magnon-magnon coupling, antiferromagnetic nanostructures are rapidly growing and are expected to dominate this research field in the coming years. Finally, associated topics like nutation dynamics and nanomagnet antenna are briefly discussed. Despite showing a great progress, only a small fraction of nanomagnetism and its ancillary topics have been explored so far and huge efforts are envisaged in this evergrowing research area in the generations to come.

A total of 327 spectra were obtained using FORS1 at the VLT, out of which 266 are galaxies with secure redshifts. In this paper, we use these data for confirming the existence of overdensities in redshift space at the approximate same location as the matched-filter detections in the projected distribution of galaxies from the EIS I-band imaging survey. The spectroscopic redshifts, associated to these overdensities, are consistent but, in general, somewhat lower than those predicted by the matched-filter technique. Combining the systems presented here with those analyzed earlier, we have spectroscopically confirmed a total of nine overdensities in the redshift range 0.6

We have considered three parameters of the model, the Landau mass $m_L$, the nuclear compressibility $K_0$, and the value of the symmetry energy $S_0$, all at saturation density $n_0$. As a result, we are able to estimate the values of the Landau mass of f $m_L = 739\pm17$ MeV, whereas the values of $K_0$ and $S_0$ fall within already known empirical values. Furthermore, for neutron stars we find the most probable value of 13 km $

description: Publication: SATS Blog (6/11/2020)This article presents my view on church attendance and safety precautions during the COVID-19 pandemic. It offers a few lessons that we can learn from the believers in the Book of Acts. It was published as a blog post on June 11, 2020 by the South African Theological Seminary (SATS). In the article, I invite the reader to see the believers’ response to persecution in Acts as a model for today’s response to the pandemic. While noting that the passages in Acts refer specifically to persecution, I call for a broader application that includes any life-threatening crisis, including Covid19. I suggest that if getting out of the path of danger was good enough for Paul and the early church, then it’s good enough for us. #Covid19 #Pandemic #Coronavirus

description: New questions inexorably follow in the wake of new discoveries, which then lead to new practical and intellectual challenges to overcome. The field of biotechnology is a veritable gold-mine in this regard, crossing the line drawn by moralists more than any other form of science with each leap forward. Prioritising pragmatism over moral axiology, biotechnology has garnered much debate over its use of living organisms in experimentation and production. On one hand, development at a cost can be necessary despite treading upon moral constraints as compared to the alternative, evolutionary entrenchment. On the other, the empathy and intellect to exercise morality can be considered the defining feature of humanity as compared to other species’. Maintaining a balance between the two is ideal but as was observed by Min Yan, there is much ambiguity within this area.1

description: Prof Lucy Reed once aptly described due process as a person’s right “not to be deprived of their property or their rights without the fair opportunity to defend themselves before neutral judges”.1 Indeed, this statement succinctly encapsulates one of the most salient cornerstones upon which law and society has rested for centuries, since the inception of the Magna Carta of England. Fair and equal treatment of people through impartial judicial systems has thence become an integral element of human civilisation, due process being the constitutional assurance that an individual’s rights against the State shall be safeguarded. However, as with all matters of such weight, due process has engendered controversy in both substantive and procedural aspects. This article will focus on exploring and assessing the oscillation of the balance of due process between justice and misuse, as well as potential resolutions to the concomitant problems.

description: Family farm is a new type of agricultural operation, and the research on ecological compensation for its production behavior is conducive to consolidating the basic position of agriculture and protecting agricultural resources and environment. By summarizing and drawing lessons from the domestic research results in related fields, the family farm is selected as the object, and the opportunity cost method is used to analyze the setting of the ecological compensation standard of the family farm. The basic framework of ecological compensation mechanism of family farm is constructed from three aspects: ecological compensation responsibility determination mechanism; compensation object establishment mechanism; compensation standard determination and mode selection mechanism. The operation mechanism of ecological compensation of family farm is analyzed from three aspects: farmer; farm production; resources and environment. The results show that the family farms' pursuit of agricultural products and ecological services is the response mechanism of ecological compensation for their production behavior. On the basis of this, this paper puts forward some measures and suggestions to ensure the ecological compensation mechanism of family farms from three aspects: perfecting the land use system; widening the compensation channels; constructing the green GDP accounting.

Demographic patterns and processes in Mazzaella splendens (Gigartinales, Rhodophyta) at Second Beach, Barkley Sound
Creators: name: Dyck, Leonard James
Publisher: name: University of British Columbia
Year: 2009

description: In this research I examined the demography of Mazzaella splendens (Setchell et Gardener) Fredericq at Second Beach, Barkley Sound. A set of demographic patterns consistent with all previous studies of M. splendens was hypothesized and tested in a new location to determine the generality of these patterns. To that end seasonal changes in density of genets and modules of gametophytes vs. tetrasporophytes were measured approximately monthly over three years. Survival, new blade production, blade size and reproduction were also measured to determine the demographic mechanisms underlying changes in population density. Patterns consistent with all previous studies of Mazzaella splendens are: 1) change from high summer to low winter population density in wave-sheltered areas with 2) a decreasing magnitude in this fluctuation as wave exposure increases and 3) a change from summer haploid to diploid dominance as wave exposure increases. These patterns may be common throughout the species range. Seasonal alternation in phase dominance in wave-sheltered areas, consistent with all previous studies, did not occur at Second Beach. Differential survival was not present between life history phases, but there was evidence of differential production of new blades. These results do not support a previous hypothesis that the alternate isomorphic life history phases of M. splendens are diverging ecologically along r and K lines. In a wave-sheltered area, 85 - 90% of modules were smaller than the size for which previous studies had predicted differential survival between phases, but even within the appropriate size class differential survival was absent. In a wave-exposed area, haploid modules lost more tissue than diploid modules, apparently reconfiguring surface area in response to wave force. Seasonally restricted reproduction, previously observed in other populations, was not present at Second Beach. Reproduction did not negatively affect survival. Evidence for slowing of growth after the onset of reproduction, and a time requirement before onset of reproduction, were mixed.

description: Non-Hermitian descriptions of quantum matter have seen impressive progress recently, with major advances in understanding central aspects such as their topological properties or the physics of exceptional points, the non-Hermitian counterpart of critical points. Here, we use single-photon interferometry to reconstruct the non-Hermitian Kibble-Zurek mechanism and its distinct scaling behavior for exceptional points, by simulating the defect production upon performing slow parameter ramps. Importantly, we are able to realise also higher-order exceptional points, providing experimental access to their theoretically predicted characteristic Kibble-Zurek scaling behaviour. Our work represents a crucial step in increasing the experimental complexity of non-Hermitian quantum time-evolution. It thus also furthers the quest to move the frontier from purely single-particle physics towards increasingly complex settings in the many-body realm.

description: The features of social support for patients with depressive disorders were studied taking into account age and gender factor. Clinical and psychological examination of 107 men and 138 women with depressive disorders revealed a low level of social support from family, friends and significant others. The highest level of social support for patients was found from friends, slightly lower – from family, and the lowest – from significant others. The indicators of social support in all spheres decrease with age; they are maximum at the age under 30 years, and the minimum at the age 45 years and older. Women enjoy greater social support from family, friends, and significant others than men, but these differences were statistically significant only in the younger age group (under 30 years). An inverse correlation was found between psychopathological symptoms and the level of social support of family, friends and significant others. The correlation is weak or moderate (correlation coefficients up to 0.551), which indicates complex patterns of social support for patients with depressive disorders.

description: More effective sharing of the knowledge generated by agricultural research and development (R&D) will enhance global efforts to reduce poverty, hunger and environmental degradation. Major meetings provide a useful opportunity for introducing knowledge sharing (KS) attitudes, methods and tools to R&D organizations. Such events can promote awareness of new types of collegial relationships and foster more creative scientific collaboration. If they are to successfully perform these functions, however, the meeting organizers must plan carefully, identifying the KS techniques that are most appropriate to the defined objectives. Feedback mechanisms (before, during and after the event) are also required. While major meetings can be an entry point for KS into an organization, they will not necessarily lead to mainstreaming of the concept. It is important to incorporate KS into the whole information continuum; a process that includes internal and external communication channels and involves all the organization’s stakeholders. For KS to lead to organizational change and sustainable improvements in performance, top-level management must be committed and meeting results must be followed through.

description: The general Lagrangian for maximal supergravity in five spacetime dimensions is presented with vector potentials in the \bar{27} and tensor fields in the 27 representation of E_6. This novel tensor-vector system is subject to an intricate set of gauge transformations, describing 3(27-t) massless helicity degrees of freedom for the vector fields and 3t massive spin degrees of freedom for the tensor fields, where the (even) value of t depends on the gauging. The kinetic term of the tensor fields is accompanied by a unique Chern-Simons coupling which involves both vector and tensor fields. The Lagrangians are completely encoded in terms of the embedding tensor which defines the E_6 subgroup that is gauged by the vectors. The embedding tensor is subject to two constraints which ensure the consistency of the combined vector-tensor gauge transformations and the supersymmetry of the full Lagrangian. This new formulation encompasses all possible gaugings.

description: A major challenge in operating multi-qubit quantum processors is to mitigate multi-qubit coherent errors. For superconducting circuits, besides crosstalk originating from imperfect isolation of control lines, dispersive coupling between qubits is a major source of multi-qubit coherent errors. We benchmark phase errors in a controlled-phase gate due to dispersive coupling of either of the qubits involved in the gate to one or more spectator qubits. We measure the associated gate infidelity using quantum process tomography. In addition, we point out that, due to coupling of the gate qubits to a non-computational state during the gate, two-qubit conditional phase errors are enhanced. Our work is important for understanding limits to the fidelity of two-qubit gates with finite on/off ratio in multi-qubit settings.

description: The achievement in cooling alkali atomic gases, such as $^{87}$Rb, $^{23}$Na and $^{7}$Li, to quantum degeneracy opens up a way to study magnetism in spinor bosons, because these constituent atoms usually have a hyperfine spin degree of freedom. This article reviews several basic problems related to the ferromagnetic phase transition in spinor atomic Bose gases from a theoretical perspective. After a brief discussion on various possible origins of the ferromagnetic interaction, the phase diagram of the ferromagnetically coupled spinor bosons is investigated. It is found that the ferromagnetic transition occurs always above Bose-Einstein condensation and the Bose condensate is fully polarized. The low-lying collective excitations of the spinor condensate, including spin and density modes, are discussed. The spectrum of the density mode is of the Bogliubov form and the spin wave spectrum has a $k^2$-formed dispersion relation at long wavelengths. The spin-wave stiffness coefficient contains contribut

description: This working paper explores the intricate relationship between data protection regulations and press freedom in Europe, with a particular emphasis on the misuse of data protection laws to initiate Strategic Lawsuits Against Public Participation (SLAPPs). The paper begins by analyzing case law, where legal actions based on the General Data Protection Regulation (GDPR) have been used to suppress journalistic efforts investigating high-level corruption and the misuse of public funds. The Hungarian Forbes case is highlighted to demonstrate the onerous legal obligations placed on the press and the potential for Data Protection Authorities (DPAs) to function as de facto instruments of SLAPPs. The working paper then examines the risks of the absence of a coherent exemption regime under Article 85 of the GDPR across EU Member States, which intensifies the conflict between different fundamental rights. It argues that the GDPR, with its extensive procedural requirements and enforceable rights, can be exploited to undermine press freedom, particularly when DPAs prioritize data protection over freedom of expression. The paper concludes by stressing the need for a more balanced approach within the GDPR framework, proposing legal interpretations and procedural safeguards to prevent the misuse of data protection laws against the press. It suggests EU institutions to proactively provide guidance to assist DPAs in aligning GDPR enforcement with press freedoms and urges judicial bodies to offer clearer jurisprudence to resolve conflicts between data protection and freedom of expression.

description: We provide a general framework on the coefficients of the graph polynomials of graphs which are Cartesian products. As a corollary, we prove that if $G=(V,E)$ is a graph with degrees of vertices $2d(v), v\in V$, and the graph polynomial $\prod_{(i,j)\in E} (x_j-x_i)$ contains an "almost central" monomial (that means a monomial $\prod_v x_v^{c_v}$, where $|c_v-d(v)|\leqslant 1$ for all $v\in V$), then the Cartesian product $G\square C_{2n}$ is $(d(\cdot)+2)$-choosable.

description: This Brief reports the results of a study that explored the role of human resources policies and practices in fostering knowledge sharing and organizational learning. The study examined six centres of the Consultative Group on International Agricultural Research (CGIAR) and six organizations that are considered to be leaders in the field of knowledge sharing and organizational learning. Five of these were public or non-governmental and the sixth was a private corporation. All the organizations studied (including the CGIAR centres) are promoting knowledge sharing and organizational learning to some extent, generally in the context of broader organizational change. Some have comprehensive, integrated approaches to organizational change, but most efforts tend to be small-scale, even ad hoc. It is sometimes assumed that CGIAR centres are behind other research and development organizations in knowledge sharing and organizational learning, but our findings indicate that, while most of the centres in the study lack comprehensive strategies, some are actively pursuing promising initiatives from which others can learn.

The volume flux group is an invariant of the underlying manifold, whose non-vanishing implies that the manifold resembles one with a circle action with homologically essential orbits.

description: The adrenal gland is a small endocrine organ with inherent regenerative capacity. Numerous studies proposed a stem cell niche located in the capsule of adrenal cortex. This project investigated mRNA and protein spatial expression of potential stem cell markers in the adrenal cortex. One of these markers (Thy-1) was used to isolate potential stem cells from dispersed primary adrenal cortex cells using magnetic-activated cell sorting (MACS). Thy-1 positive cells were monitored while they survived in vitro for over one year. Thy-1 cells were demonstrated to be undifferentiated fibroblastic-like cells with characteristics similar to those of mesenchymal stem cells in vitro such as plastic adherent, can form colonies, the confluent cells have a whirlpool-like formation and the significant (P< 0.05) increase of Thy-1 expression during cultivation in vitro. Thy-1 positive cells showed the expression of other stem cell markers such as Wt1, Etv5 and ID4. The monitoring of Thy-1 positive cells behavioural changes in vitro showed slow division rate, slow cell migration and the coexistence of senescent cells in their early months of cultivation. In comparison, in the late months of cultivation, the cells showed a significant (P< 0.05) increase in cell division rate and cell migration similar to cancer cell behaviour in vitro. As these cells were generally undifferentiated and they have characteristics of mesenchymal stem cells, differentiation attempts were first conducted using external differentiation factors (forskolin, ACTH and AT20 cell line media). However, the results showed non-significant responses to these treatments. The second differentiation experiments were conducted by forcing expression of Sf1 protein in Thy-1 positive cells using a cloning vector. Transfection with Sf1caused a significant (P< 0.05) reduction in ID4 mRNA expression and significantly (P< 0.05) elevated the expression of the progenitor marker Gli1 and the expression of steroidogenic enzyme genes (Cyp11A1 and 3βHSD) consistent with previous reports for several mesenchymal stem cell types.
The Influence of the Insurance Act 2015 on the Pre-Contractual Duty of Fair Presentation in UK Insurance Law

description: The Insurance Act 2015 (IA) represents the formulation of long overdue reform to British insurance law. The legislation preceding it, the Marine Insurance Act 1906 (MIA), had been the authority on the subject since the reign of King Edward VII. However, with the tides of time, so changed insurable risks and public perceptions of the concept of insurance. Therefore, after meticulous joint reviews conducted alongside it’s Scottish counterpart since 2006, the Law Commission came to the conclusion that the MIA had been rendered obsolete. The field of insurance had evolved into a complex and sophisticated area, and the rigidity of the antiquated MIA was not ideally suited for the realities of commercial practices of the 21st century.

description: This Brief describes a ‘culture study’ carried out to explore how different staff groups perceive the culture of an international research centre and how the management of staff diversity issues affects the work environment and organizational performance. The perceptions of various staff groups were analysed in relation to five aspects of organizational culture: institutional climate; global competitiveness; empowerment and group motivation; work–life balance; and equity in gender and diversity. The study identified what staff believed to be the key strengths and weaknesses in the organization’s culture and detected four strategic areas for improvement: internal organizational communications; re-design of job positions and responsibilities; multi-cultural competencies; and gender awareness in the workplace. The diagnostic process is described, as well as the follow-up actions taken to improve the management of gender and diversity in the centre.
