A Comparison of Audio Recordings and Therapist's Process Notes in Child and Adolescent Psychoanalytic Psychotherapy

Therapistsʼ process notes - written descriptions of a session produced shortly afterwards from memory - hold a significant role in child and adolescent psychoanalytic psychotherapy. They are central in training, in supervision, and in developing oneʼs understanding through selfsupervision and forms of psychotherapy research. This thesis examines such process notes through a comparison with audio recordings of the same sessions. In so doing, it aims to generate theory that might illuminate the causes of significantly patterned discrepancies between the notes and recordings, in order to understand more about the processes at work in psychoanalytic psychotherapy and to explore the nature of process notes, their values and limitations. The literature searches conducted revealed limited relevant studies. All identified studies that compare process notes with recordings of sessions seek to quantify the differences between the two forms of recording. Unlike these, this thesis explores the meaning of the differences between process notes and recordings through qualitative data analysis. Using psychoanalytically informed grounded theory, in total nine sets of process notes and recordings from three different psychoanalytic psychotherapists are analysed. The analysis identifies eight core categories of findings. Initial theories are developed from these categories, most significantly concerning the role and influence of a ʻcore transference dynamicʼ between therapist and patient. Further theory is developed on the nature and function of process notes as a means for the therapistʼs conscious and unconscious processing of the session, as well as on the nature of the influence of the relationships – both internal and external – within which they are written. In the light of the findings, a proposal is made for a new approach for learning about the patient and clinical work, ʻthe comparison methodʼ (supervision involving a comparison of process notes and recordings), and, in particular, for its inclusion within the training of psychoanalytic psychotherapists. Further recommendations for research are also made.

Investigation on reproduction process in two species of crab Eriphia sebana and Ocypode saratan in the intertidal zone of Chabahar area

The present study with headline investigation on reproduction in two species of Crab Eriphia sebana and Ocypode saratan was carried out in the intertidal zone of Chabahar in thirteen month from December 2004 to December 2005. Checked samplings have been taken, 45 number Crab monthly from any four stations by manual or use trap. During this study the following subjects were measured: Temperature range and salinity, Measurable coast granule, Determination of sex ratio, Relations carapace width with carapace length, Carapace width with total body weight, Gonad weight, gonadosomatic index, condition factor, gastrosomatic index, investigation content in stomach, LM50, Growth parameters, plenty distribution length and width and gonad weight and total body weight. Studied on measurable coast granule were expressed that Ocypode saratan in Desalination station, were nest in soils equable sand and this quantity were confirmed in Pozm station. Sex ratio were assign in desalination area and Pozm M: F 0/44:0/56 and in Tiss and Chabahar M: F 0/45:0/55.

Marketing in SMEs: the sales process of SMEs on the food and drink industry.

There would appear to be varied approaches to the sales process practiced by SMEs in how they go about locating target customers, interfacing with prospects and new customers, presenting the benefits and features of their products and services, closing sales deals and building relationships, and an understanding of what the buyers needs are in the seller-buyer process. Recent research has revealed that while entrepreneurs and small business owners rely upon networking as an important source of sales, they lack marketing competencies, including personal selling skills and knowledge of what is involved in the sales process to close sales deals and build relationships. Small companies and start-ups with innovative products and services often find it difficult to persuade potential buyers of the merits of their offerings because, while the products and services may be excellent, they have not sufficiently well-developed selling skills necessary to persuade their target customers.

The interpersonal and mental health implications of the coherence of coming out narratives for a sample of gay men in committed romantic relationships

The coming out process has been conceptualized as a developmental imperative for those who will eventually accept their same-sex attractions. It is widely accepted that homophobia, heterosexism, and homonegativity are cultural realities that may complicate this developmental process for gay men. The current study views coming out as an extra-developmental life task that is at best a stressful event, and at worst traumatic when coming out results in the rupture of salient relationships with parents, siblings, and/or close friends. To date, the minority stress model (Meyer, 1995; 2003) has been utilized as an organizing framework for how to empirically examine external stressors and mental health disparities for lesbians, gay men, and bisexual individuals in the United States. The current study builds on this literature by focusing on the influence of how gay men make sense of and represent the coming out process in a semi-structured interview, more specifically, by examining the legacy of the coming out process on indicators of wellness. In a two-part process, this study first employs the framework well articulated in the adult attachment literature of coherence of narratives to explore both variation and implications of the coming out experience for a sample of gay men (n = 60) in romantic relationships (n = 30). In particular, this study employed constructs identified in the adult attachment literature, namely Preoccupied and Dismissing current state of mind, to code a Coming Out Interview (COI). In the present study current state of mind refers to the degree of coherent discourse produced about coming out experiences as relayed during the COI. Multilevel analyses tested the extent to which these COI dimensions, as revealed through an analysis of coming out narratives in the COI, were associated with relationship quality, including self-reported satisfaction and observed emotional tone in a standard laboratory interaction task and self-reported symptoms of psychopathology. In addition, multilevel analyses also assessed the Acceptance by primary relationship figures at the time of disclosure, as well as the degree of Outness at the time of the study. Results revealed that participant’s narratives on the COI varied with regard to Preoccupied and Dismissing current state of mind, suggesting that the AAI coding system provides a viable organizing framework for extracting meaning from coming out narratives as related to attachment relevant constructs. Multilevel modeling revealed construct validity of the attachment dimensions assessed via the COI; attachment (i.e., Preoccupied and Dismissing current state of mind) as assessed via the Adult Attachment Interview (AAI) was significantly correlated with the corresponding COI variables. These finding suggest both methodological and conceptual convergence between these two measures. However, with one exception, COI Preoccupied and Dismissing current state of mind did not predict relationship outcomes or self-reported internalizing and externalizing symptoms. However, further analyses revealed that the degree to which one is out to others moderated the relationship between COI Preoccupied and internalizing. Specifically, for those who were less out to others, there was a significant and positive relationship between Preoccupied current state of mind towards coming out and internalizing symptoms. In addition, the degree of perceived acceptance of sexual orientation by salient relationship figures at the time of disclosure emerged as a predictor of mental health. In particular, Acceptance was significantly negatively related to internalizing symptoms. Overall, the results offer preliminary support that gay men’s narratives do reflect variation as assessed by attachment dimensions and highlights the role of Acceptance by salient relationship figures at the time of disclosure. Still, for the most part, current state of mind towards coming out in this study was not associated with relationship quality and self-reported indicators of mental health. This finding may be a function of low statistical power given the modest sample size. However, the relationship between Preoccupied current state of mind and mental health (i.e., internalizing) appears to depend on degree of Outness. In addition, the response of primary relationships figures to coming out may be a relevant factor in shaping mental health outcomes for gay men. Limitations and suggestions for future research and clinical intervention are offered.

Para uma pedagogia do reconhecimento: da concriação à pratica vocativa

Esta dissertação assume, na sua maior abrangência, a feitura de uma articulação entre a sustentação originária e constitutiva do ser humano, a manifestação concreta do sentido existencial do ato pedagógico e os seus modos de realização: dialógico, comunitário, personalista e humanista. Neste sentido, a nossa proposta passa inicialmente por uma procura do sujeito através do alcance da pessoa, do homem ao indivíduo (nas suas diversas vicissitudes), até à sua concretização numa consciência pedagógica precursora do agir, do conhecer, do sentir e, fundamentalmente, do ato de “Reconhecer”, este tido, por nós, como o processo fundamentador e fomentador de uma Pedagogia do Reconhecimento. É um percurso inovador na medida em que parte de uma Antropologia Filosófica e de uma Antroposofia, passando pelos meandros processuais da consciência lonerganiana e da fenomenologia buberiana da relação, pretendendo promover, no seu culminar, uma ambiência cultural de pedagogia dialógica inserida num topos comunitário, pressuposta e implicitamente proposta numa Teoria do Reconhecimento, que se situa na geografia disciplinar da Filosofia da Educação, e nas “Dinâmicas das Relações Interpessoais”. Temos, pois, que o seu epílogo é o reconhecimento: como resultado radical e subtil manifestado na intersubjetividade. A Pedagogia do Reconhecimento como concriação e ação vocativa está fundamentada num itinerário de estruturas idiossincráticas de sustentação do modo como “ser-aí” se faz (constrói e realiza). Partiremos da desaxialização do “Eu” tópico (anthropos) para uma estrutura transversal dialógica. Entendemos que toda a vida verdadeira é relação, afirmação buberiana que, só por si, derruba a clássica fronteira tópica e abre espaço à condição dialógica e essencial do fazer do ser humano. O papel do reconhecimento do “outro”, no homem, é um fenómeno de dialogicidade que abole as fronteiras dialéticas da pura argumentação e permite o brotar da reciprocidade; Abstract: This dissertation intends, in its greater scope, to make a link between the original and constitutive support of the human being, the concrete manifestation of pedagogical act's existential sense and its embodiments: dialogical, personalistic, communitarian and humanist. Our proposal initially goes through a search of the Self through the achievement of the person, from Man to the individual (in its various vicissitudes), till its development in a pedagogical conscience that is a precursor of action, knowing, feeling and, fundamentally, of the act of “Recognize”, as a justifying and instigating process of a Pedagogy of Recognition. It is an innovative path in the sense that it initiates itself from a Philosophical Anthropology and from an Anthroposophy and it continues through the procedural intricacies of lonerganian consciousness and buberian phenomenology of relation, intending to promote, in its culmination, a cultural ambience of dialogic pedagogy, inserted in a communitarian topos, presupposed and implicitly proposed in a Recognition Theory, that places itself in the disciplinary geography of Philosophy of Education and in the “Dynamics of Interpersonal Relationships”. Therefore, the epilogue is the recognition: as a radical and subtle outcome, expressed in the intersubjectivity. The Pedagogy of Recognition as co-creation and vocative practice is based on a route of idiosyncratic structures of support of the way in how to be there is done (built and accomplished). We start from the de-axialization of the topic “Self” (anthropos) to a transversal dialogical structure. We defend that all true life is relationship, a buberian statement that all alone drops the topical classical border and makes room for the dialogical and essential condition of doing of the human being. The role of recognition of the “other”, in Man, is a dialogical phenomenon that abolishes the dialectic borders of pure argument and allows the sprouting of reciprocity.

Development Of Interpersonal Relationships in Global Virtual Teams

This study investigates the development of relationships in same global virtual team working on different projects. The purpose is to explore how do interpersonal relationships develop in terms of characteristics of virtuality and if there is any influence of project lifespan on the development of these relationships. Since relationships are dynamic in nature and are influenced by multiple levels of variables including individual, group and organizational level, therefore characteristics of virtuality have been considered from all these aspects so as to study their influence on development of relationships. In this study, relationships have been studied at two different levels. At first, dyadic relationships between two members of a GVT have been analyzed and thereafter, focus has been on the development of relationships among the team, based on these dyads. Characteristics having influence on development of relationships include trust, physical distance, time zone difference, cultural and language differences, level of formalization in the organization and means of communication used by team members. Level of formalization and means of communication are two characteristics which emerged after empirical study and are found to have direct influence on development of relationships. Remaining characteristics have been identified through literature review. In order to conduct the study, qualitative methodology has been applied. Empirical data has been collected based on a single case study while using semi-structured interviews as data gathering technique. Data analysis has been performed by applying thematic analysis along with the utilization of company documents such as work sheets, minutes of meetings and recordings of conferences. Findings of the study indicate that development of relationships, both at dyadic level and team level, is influenced by different events taking place among different members of GVT. These events have either positive or negative influence on the characteristics of virtuality, which leads to development of the relationships. It has been found that, trust, among all factors plays a greater role in development of these relations. Contrary to the belief that most conflicts arise among members of different cultures, they are equally likely to happen among the members from same culture in GVT environment. Study suggests that relationship development is not a smooth process but it fluctuates based on different events in teams. For further research, teams within large firms shall be studied along these lines. This study is an early attempt towards bringing different characteristics of virtuality together which previously, have been studied individually. It is therefore plausible to conduct similar studies so as to generalize the findings of this study which has provided a starting point.

Types of embedded ties in buyer-supplier relationships and their combined effects on innovation performance

[EN] Purpose of the paper - This research analyzes the impact of three types of embedded ties, namely, specialized complementary resources, idiosyncratic investments, and knowledge sharing, on the innovation capacity of the firms. We also study the particularities of the Machine-Tool industry. Theoretical background – Our evaluation of the embedded buyer-supplier ties is based on the potential sources of relational rents proposed by Dyer and Sing (1998). We also draw on Uzzi and Lancaster (2003), Noordhoff et al. (2011), among others, to discuss the positive and negative aspects of embedded ties. Design/Methodology/Approach ‐ Using data from a survey of 202 European machine-tool firms acting as buyers and sellers, we propose and evaluate a Structural Equation model. Findings ‐ Only knowledge-sharing routines exert a significant positive effect on product innovation performance. Neither an increase in the idiosyncratic investments nor in complementary resources and capabilities enhance innovation performance. Also, knowledge-sharing routines mediate in the effect from idiosyncratic investments on innovation performance. Research Limitations. ‐ The machine tool industry has unique characteristics that make this generalization difficult. Also, there is considerable difficulty associated with testing more deeply the interrelations among these embedded ties in the long run. It is plausible to understand that these interrelations operate within a gradual process. Originality/Value/Contribution of Paper ‐ This research contributes to a better understanding of the role of embedded ties on innovativeness. To the best of our knowledge, there is no previous international empirical research analyzing the mediation effects among specialized complementary resources, idiosyncratic investments and knowledge sharing, and their effects on the innovation capacity of firms.

The commodification of culture in the Thai tourism context: a study of culinary experiences in touristic traditional markets

The purpose of the thesis is to examine the relationship between tourism and the local culture expressed in culinary experiences offered in the traditional, nostalgic-themed markets that have arisen as popular attractions in the 21 st century. Central to the thesis is an examination of how the traditional cultural values are articulated in the production, promotion and consumption of culinary experiences in order to understand the value of culture when embedded in the process of commodification, as well as to understand influential socio-cultural factors. The thesis investigates the potential of traditional markets to promote food as the main attraction in the market. Field studies were conducted from December 2012–March 2014 in eight traditional markets in the central region of Thailand. Based on the ethnographic approach in studying the narratives in the markets, a variety of methods were implemented in the process of data collection. Besides observational analysis of the venue, semi-structured interviews and the self-administered questionnaires were used to collect data from actors who engage in food experiences, including management team members, food traders and visitors. Data was also collected from interviews with officers working for Tourism Authority of Thailand (TAT).  Keys findings of the thesis reveal that the cultural expressions of food experience in each market is an outcome of both the interactions of worldviews expressed by actors involved in the traditional market and the socio-cultural condition of Thailand. The relationships between stakeholders’ attitudes towards food experiences and the commercial potentials and limitations of food were analysed. The analysis of the cultural value of culinary experiences demonstrates that the existing academic discussions of the authenticity of tourism are insightful in explaining the character of food experiences offered in this tourism scenario. Most importantly, authenticity in tourism experiences, being a desirable element in culinary experiences, is a reflection of the how the pre-modern aspect of Thai society is embraced in a contemporary context. In addition, the commodification of culinary culture generates multidimensional consequences on the value of traditional culture and local lives. Moreover, the performance of culinary experiences can be viewed from the perspective of how Thai society interacts with globalization. The thesis also points out that it is possible to compare the situation of the traditional markets with the marketing positioning of food in Thai tourism marketing policy.

Contribution of plant phytochemicals to organic homeostasis: focus on the aging process and opportunistic infections

Aging process is conceived as a normal stage during human life cycle, but it is also considered a hot topic among scientists and medical community. Alarming rates of premature aging and oxidative stress-related diseases have increasingly affect human individuals. Stress, pollution and exposition to chemical substances are considered the main triggering factors for those conditions; in addition, they also suppress the immune system and, therefore, improve organic vulnerability and occurrence of opportunistic infections [I]. Apart from the associated morbidity and mortality, the increasing rates of antimicrobial resistance improve the severity of the clinical conditions [2]. Botanical preparations possess a multitude of bioactive properties, namely acting as antimicrobials, antioxidants, and homeostasis modulators. Thus, upcoming alternatives, mainly based in plant phytochemicals, are necessary to improve the wellbeing as also life expectancy of individuals. The present study aims to evaluate and to compare both antioxidant and antimicrobial properties of plant extracts rich in phenolic compounds. Among the tested plants, Glycyrrhiza glabra L. (licorice) evidenced the most pronounced free radicals scavenging and antimicrobial effects, followed by Salvia officina/is L. (sage), Thymus vulgaris L. (thyme) and Origanum vulgare L. (oregano). Eucalyptus globulus Labill. (blue gum) and Juglans regia L. (walnut) also showed a high effect, while Pterospartum tridentatum (L.) Willk. (carqueja) and Rubus ulmifolius Schott (elm leaf blackberry) displayed moderate effects, and lastly, Tabebuia impetigirwsa (Mart. ex DC) Standley (pau d'arco), Foeniculum vulgare Miller (fennel), Rosa canina L. (rose hips) and Matricaria recutita L. (chamomile) gave only slight effects. In general, the most pronounced bioactivities were observed in the plant preparations (infusion>decoction>hydromethanolic extract) with higher levels of phenolic compounds (both flavonoids and phenolic acids). The observed synergisms between the phenolic compounds present in the extracts highlight the use of phytochemicals as future health promoters. However, further studies are necessary to understand the effective mode of action of individual phenolic constituents as also the existence of polyvalence relationships between them.

Effect of remote ischaemic preconditioning in cardiac dysfunction and end-organ injury following cardiac surgery with cardiopulmonary bypass in children: A translational approach investigating clinical outcome and myocardial molecular biology

Congenital heart disease (CHD) is the most common birth defect, causing an important rate of morbidity and mortality. Treatment of CHD requires surgical correction in a significant percentage of cases which exposes patients to cardiac and end organ injury. Cardiac surgical procedures often require the utilisation of cardiopulmonary bypass (CPB), a system that replaces heart and lungs function by diverting circulation into an external circuit. The use of CPB can initiate potent inflammatory responses, in addition a proportion of procedures require a period of aortic cross clamp during which the heart is rendered ischaemic and is exposed to injury. High O2 concentrations are used during cardiac procedures and when circulation is re-established to the heart which had adjusted metabolically to ischaemia, further injury is caused in a process known as ischaemic reperfusion injury (IRI). Several strategies are in place in order to protect the heart during surgery, however injury is still caused, having detrimental effects in patients at short and long term. Remote ischaemic preconditioning (RIPC) is a technique proposed as a potential cardioprotective measure. It consists of exposing a remote tissue bed to brief episodes of ischaemia prior to surgery in order to activate protective pathways that would act during CPB, ischaemia and reperfusion. This study aimed to assess RIPC in paediatric patients requiring CHD surgical correction with a translational approach, integrating clinical outcome, marker analysis, cardiac function parameters and molecular mechanisms within the cardiac tissue. A prospective, single blinded, randomized, controlled trial was conducted applying a RIPC protocol to randomised patients through episodes of limb ischaemia on the day before surgery which was repeated right before the surgery started, after anaesthesia induction. Blood samples were obtained before surgery and at three post-operative time points from venous lines, additional pre and post-bypass blood samples were obtained from the right atrium. Myocardial tissue was resected during the ischaemic period of surgery. Echocardiographic images were obtained before the surgery started after anaesthetic induction and the day after surgery, images were stored for later off line analysis. PICU surveillance data was collected including ventilation parameters, inotrope use, standard laboratory analysis and six hourly blood gas analysis. Pre and post-operative quantitation of markers in blood specimens included cardiac troponin I (cTnI) and B-type natriuretic peptide (BNP), inflammatory mediators including interleukins IL-6, IL-8, IL-10, tumour necrosis factor (TNF-α), and the adhesion molecules ICAM-1 and VCAM-1; the renal marker Cystatin C and the cardiovascular markers asymmetric dymethylarginine (ADMA) and symmetric dymethylarginine (SDMA). Nitric oxide (NO) metabolites and cyclic guanosine monophosphate (cGMP) were measured before and after bypass. Myocardial tissue was processed at baseline and after incubation at hyperoxic concentration during four hours in order to mimic surgical conditions. Expression of genes involved in IRI and RIPC pathways was analysed including heat shock proteins (HSPs), toll like receptors (TLRs), transcription factors nuclear factor κ-B (NF- κ-B) and hypoxia inducible factor 1 (HIF-1). The participation of hydrogen sulfide enzymatic genes, apelin and its receptor were explored. There was no significant difference according to group allocation in any of the echocardiographic parameters. There was a tendency for higher cTnI values and inotropic score in control patients post-operatively, however this was not statistically significant. BNP presented no significant difference according to group allocation. Inflammatory parameters tended to be higher in the control group, however only TNF- α was significantly higher. There was no difference in levels of Cystatin C, NO metabolites, cGMP, ADMA or SDMA. RIPC patients required shorter PICU stay, all other clinical and laboratory analysis presented no difference related to the intervention. Gene expression analysis revealed interesting patterns before and after incubation. HSP-60 presented a lower expression at baseline in tissue corresponding to RIPC patients, no other differences were found. This study provided with valuable descriptive information on previously known and newly explored parameters in the study population. Demographic characteristics and the presence of cyanosis before surgery influenced patterns of activity in several parameters, numerous indicators were linked to the degree of injury suffered by the myocardium. RIPC did not reduce markers of cardiac injury or improved echocardiographic parameters and it did not have an effect on end organ function; some effects were seen in inflammatory responses and gene expression analysis. Nevertheless, an important clinical outcome indicator, PICU length of stay was reduced suggesting benefit from the intervention. Larger studies with more statistical power could determine if the tendency of lower injury and inflammatory markers linked to RIPC is real. The present results mostly support findings of larger multicentre trials which have reported no cardiac benefit from RIPC in paediatric cardiac surgery.

Applying the Analytic Hierarchy Process in healthcare research: A systematic literature review and evaluation of reporting

Background: The Analytic Hierarchy Process (AHP), developed by Saaty in the late 1970s, is one of the methods for multi-criteria decision making. The AHP disaggregates a complex decision problem into different hierarchical levels. The weight for each criterion and alternative are judged in pairwise comparisons and priorities are calculated by the Eigenvector method. The slowly increasing application of the AHP was the motivation for this study to explore the current state of its methodology in the healthcare context. Methods: A systematic literature review was conducted by searching the Pubmed and Web of Science databases for articles with the following keywords in their titles or abstracts: "Analytic Hierarchy Process," "Analytical Hierarchy Process," "multi-criteria decision analysis," "multiple criteria decision," "stated preference," and "pairwise comparison." In addition, we developed reporting criteria to indicate whether the authors reported important aspects and evaluated the resulting studies' reporting. Results: The systematic review resulted in 121 articles. The number of studies applying AHP has increased since 2005. Most studies were from Asia (almost 30 %), followed by the US (25.6 %). On average, the studies used 19.64 criteria throughout their hierarchical levels. Furthermore, we restricted a detailed analysis to those articles published within the last 5 years (n = 69). The mean of participants in these studies were 109, whereas we identified major differences in how the surveys were conducted. The evaluation of reporting showed that the mean of reported elements was about 6.75 out of 10. Thus, 12 out of 69 studies reported less than half of the criteria. Conclusion: The AHP has been applied inconsistently in healthcare research. A minority of studies described all the relevant aspects. Thus, the statements in this review may be biased, as they are restricted to the information available in the papers. Hence, further research is required to discover who should be interviewed and how, how inconsistent answers should be dealt with, and how the outcome and stability of the results should be presented. In addition, we need new insights to determine which target group can best handle the challenges of the AHP. © 2015 Schmidt et al.

Cultivating Collaborative Relationships: A Case Study of Teacher Collaboration and Professional Development

Students often receive instruction from specialists, professionals other than their general educators, such as special educators, reading specialists, and ESOL (English Speakers of Other Languages) teachers. The purpose of this study was to examine how general educators and specialists develop collaborative relationships over time within the context of receiving professional development. While collaboration is considered essential to increasing student achievement, improving teachers’ practice, and creating comprehensive school reform, collaborative partnerships take time to develop and require multiple sources of support. Additionally, both practitioners and researchers often conflate collaboration with structural reforms such as co-teaching. This study used a retrospective single case study with a grounded theory approach to analysis. Data were collected through semi-structured interviews with thirteen teachers and an administrator after three workshops were conducted throughout the school year. The theory, Cultivating Interprofessional Collaboration, describes how interprofessional relationships grow as teachers engage in a cycle of learning, constructing partnership, and reflecting. As relationships deepen some partners experience a seamless dimension to their work. A variety of intrapersonal, interpersonal, and external factors work in concert to promote this growth, which is strengthened through professional development. In this theory, professional development provides a common ground for strengthening relationships, knowledge about the collaborative process, and a reflective space to create new collaborative practices. Effective collaborative practice can lead to aligned instruction and teachers’ own professional growth. This study has implications for school interventions, professional development, and future research on collaboration in schools.

Effects of nitrogen limitation on Dunaliella sp.–Alteromonas sp. interactions: from mutualistic to competitive relationships.

Interactions between photosynthetic and non-photosynthetic microorganisms play an essential role in natural aquatic environments and the contribution of bacteria and microalgae to the nitrogen cycle can lead to both competitive and mutualistic relationships. Nitrogen is considered to be, with phosphorus and iron, one of the main limiting nutrients for primary production in the oceans and its availability experiences large temporal and geographical variations. For these reasons, it is important to understand how competitive and mutualistic interactions between photosynthetic and heterotrophic microorganisms are impacted by nitrogen limitation. In a previous study performed in batch cultures, the addition of a selected bacterial strain of Alteromonas sp. resulted in a final biomass increase in the green alga Dunaliella sp. as a result of higher nitrogen incorporation into the algal cells. The present work focuses on testing the potential of the same microalgae–bacteria association and nitrogen interactions in chemostats limited by nitrogen. Axenic and mixed cultures were compared at two dilution rates to evaluate the impact of nitrogen limitation on interactions. The addition of bacteria resulted in increased cell size in the microalgae, as well as decreased carbon incorporation, which was exacerbated by high nitrogen limitation. Biochemical analyses for the different components including microalgae, bacteria, non-living particulate matter, and dissolved organic matter, suggested that bacteria uptake carbon from carbon-rich particulate matter released by microalgae. Dissolved organic nitrogen released by microalgae was apparently not taken up by bacteria, which casts doubt on the remineralization of dissolved organic nitrogen by Alteromonas sp. in chemostats. Dunaliella sp. obtained ammonium-nitrogen more efficiently under lower nitrogen limitation. Overall, we revealed competition between microalgae and bacteria for ammonium when this was in continuous but limited supply. Competition for mineral nitrogen increased with nitrogen limitation. From our study we suggest that competitive or mutualistic relationships between microalgae and bacteria largely depend on the ecophysiological status of the two microorganisms. The outcome of microalgae–bacteria interactions in natural and artificial ecosystems largely depends on environmental factors. Our results indicate the need to improve understanding of the interaction/s between these microbial players
