Transcript: CONTAINER PORT QUALITY THROUGH INDUSTRIAL SERVICES MARKETING: A STUDY OF TANGER MED PORT Research Focus Research Problematic Methodology Contributions Obstacles Research perspectives Outline Introduction Research Problematic Research problematic ISO certifications and container ports Marketing mix and container ports Emergence of service marketing discipline Research question How could a container port achieve the quality of its services through marketing? Research question Research sub-questions • What is a port service? • What are its characteristics? • What are the process modes of the port services? • How can the behaviour of the different actors present during the inter-organizational exchanges of the service be apprehended? • What approach can be taken to the marketing of port services? • What are the qualitative dimensions of a port service? • How to measure the perception of the quality of the port service by the actors? • And finally, How to improve the quality of port service through service marketing? Research sub-questions Defintions: Industrial services The definition of industrial service faces the same obstacles as those encountered in the definition of service The classification according to the interactive approach seems to us the most adequate to the particularity of the industrial service, since the latter is identified by the nature and the content of the interactions generated during the contact with the client company. Defintions: Industrial services “The port is a land area with maritime and hinterland access that has developed into a logistics and industrial centre, playing an important role in global industrial and logistics networks” Notteboom (2007). Definitions: Port Importance of problematic Why it is important?

Not only objective indicators can measure well-being, qualitative indicators and subjective experiences are also important Overweight and obesity are on an upward trend in almost all Europe Worldwide, 31.1% of adults are physically inactive Mental disorders affected 12% of the entire population and are a major public health challenge. One person in five will develop depression. Suicide from depressive disorders is the third leading cause of death among young people Chronic diseases are the biggest contributor to mortality and disability in Europe Average expenditure ranging of 10.8% GDP in Nordic countries Why prevention? Economic and social development Quality of life of every single person Health and Prevention Real health benefits can be attained at an affordable cost (if effective strategies are adopted) Avoid diseases onset Prevention interventions are far from developed, more effort and resources must be invested in this area. WHO defines a "multi-sectoral approach” as a strategic priority to bring better health and well-being to people. NATURE ENGAGEMENT Man and Nature Theoretical underpinning: Provide physiological and psychological benefits across socioeconomic strata. Green spaces has beneficial effects such as improved mental health, reduced cardiovascular morbidity and mortality, obesity and risk of type 2 diabete (WHO, 2017) Umbrella-term: Health-related behaviours regarding human nature interactcion Passive Exposure to nature PASSIVE EXPOSURE TO NATURE Viewing nature in different ways Promote positive changes in attention, memory and mood (NORDWOOD ET AL., 2019) Provide benefits for hospitalized patients (WILSON, 1984) GREEN EXERCISE GE is physical Activity that take place in the presence of natural environment. Active exposure to nature GREEN EXERCISE Outdoor VS Indoor: lower rating of perceived exertion (GLADWELL ET AL., 2013) long therm adherence and extrinsic motivation to exercise (GLADWELL ET AL., 2013) positive influence on physical activity behaviours by providing powerful emotional experiences (CALOGIURI ET AL., 2015) Intention for future exercise (BOWLER ET AL., 2010) GE offers superior benefits on mental health and well-being factors: stress anxiety mood disturbance improve self-esteem Attention (ART) Life satisfaction Mental Health and well-being (BRATMAN ET AL., 2019) CONNECTEDNESS WITH NATURE Individual levels of feeling emotionally connected to the natural world CONNECTEDNESS WITH NATURE Including nature in the self is not a new concept. Biophilia is defined in the '80s as an innate affinity of human beings with the natural world (WILSON., 1984) Numerous studies highlight how CN is linked with well-being measures. In particular, CN seems to meet basic psychological needs (self-efficacy, relatedness) and leads to long term benefits, such as pro-social behaviour and functioning well psychologically (RYAN & DECI, 2009; SHEFFIELD & LUMBER, 2019) NATURE DISCONNECTION Urban environment (68% of the population will live in cities by 2050) (UNITED NATION) Green opportunities (BRATMAN ET AL., 2019) De-naturalisation of cities (MACINTYRE ET AL., 2019) Green World? Nature deficit disorder: Impact across generation, especially younger adults (SMITH ET AL., 2019) Happiness and life satisfaction (CAPALDI ET AL., 2014) Long-term impact on children (BUNGLEY & MILLIGAN, 2004) VIRTUAL REALITY "a computer simulation that replaces or auguments the feedback to one or more senses, giving the feeling of being mentally immersed or present in the simulation" (SHERMAN & CRAIG, 2003) Virtual Reality PRESENCE: the subjective feeling of “being in the virtual environment” IMMERSION: the extent to which a computer-generated environment is “capability of delivering an inclusive, extensive, surrounding, and vivid illusion of reality to the senses of a human participant” (SLATER AND WILBUR, 1997) Different types of VR (Screen, HMD, mixed) and video successfully used in several fields: tourism, rehabilitation, medicine and psychological Immersive Virtual Environment Immersive Virtual Environment Head Mounted Display 360 video Headset A synthetic sensory information that provide a surrounding and continuous stream of stimuli, creating the illusory perception of being enclosed within and interacting with a real environment (Loomis et al., 1999; Smith, 2015) Technological Nature "Technologies that in a various way mediate, augment and simulate our experience of the

As a result, operating a plant is still expensive. Using a lot of power has a negative environmental impact. 1- Expensive equipment and chemicals. 2-Turbidity of water should be < 10 ppm. to avoid high organic matter concentration. 3-Needs skilled labour. 4-Consume a lot of chemicals in regeneration process. 5-Non-charged particles can not be catches by resin ex: silicate Have a lot of other benefits Continuous process resulting in automatic and uninterrupted operation Low energy utilization involving neither phase nor temperature changes Modular design – no significant size limitations Minimal moving parts with low maintenance requirements No effect on form or chemistry of the contaminant Discrete membrane barrier to ensure physical separation No chemical addition requirements Membrane Processes are considered “Green” technology - no chemicals are used in the process. Methodology 1- Preparation of some filtration media by using deferment cross-linked polymers such as polyvinyl alcohol membrane. 2- Characterization and performance of the produced media 3- Evaluation of the produced media in the filtration and clarification of different kind of water. Raw water 4- A series of examinations will carry out for treated water according to the standard method of testing:- 97.5% of the water on earth is in the ocean. Only 2.5% freshwater 70% is permanently frozen in glaciers 30% is groundwater 0.3% is in rivers and lakes permeate flux , reject mechanical properties Cellulose Membrane Processes The Human Body is about 60% water in Adult Males and 55% in Adult Females. polymer Based on acrylamide are toxic Poly(DADMAC) The way to solve Problems devices Removes large solids branches rags fish Simple process may incorporate a mechanized trash removal system Protects pumps and pipes in WTP Most of suspended matter in water are negatively charged particles The stability and consequently the instability of suspended particles is a factor of different attraction and repulsion forces : Van der Waals forces Electrostatic forces Universal attraction Brownian notion Example: Reverse Osmosis Saltwater is forced through a membrane at 600 to 1000 psi Multiple layers of membranes remove as many of the salt ions as possible Increase sulfate ions cause health problems Most common coagulants: Distribution The difference – dimmensions of the tubes, but module concepts are the same. The hollow-fiber module – highest packing density 30000m2/m3. A perforated central pipe is located in the center of the module through which the feed solution enters. Synthesis and Characterization of Some Filtration media for raw and industrial water Coagulation is both a physical and a chemical process. The reactions between particles and coagulant will allow the formation of aggregates and their subsequent sedimentation. Cationic coagulants neutralize the negative charge of colloids and form a spongy mass called microflocs HOLLOW-FIBER MODULE Water Desalination Disinfection Desalination technology Chemical De-Mineralization Processes In an ion exchange reaction the exchange of ions of like sign between water and insoluble solid with which it is in contact occurs. The zeolite process and the demineralization process of water softening are based on ion exchange reactions Membrane Processes Four common types of membranes: Microfiltration Ultrafiltration Nanofiltration Reverse Osmosis Chloride ion increase corrosivity to metal Spiral-Wound membrane Natural Desalination: Water Cycle! Example: Multi-Stage Flash Desalination Process uses multiple boiling chambers kept at different atmospheric pressures Saltwater enters the system and is boiled and evaporated in each chamber Process produces clean water and brine Clean water means clear disease.

Mattia Fois Centre for Quantitative Genetics and Genomics Aarhus University Introduction Introduction Family: Poaceae Genus: Lolium Lolium Humphreys M. et al. 2010 Lolium spp. seed production takes place in many countries around the world and are commercialized for pasture, turf, and as a cover crop and sold to many different markets (red dashed arrows). L. perenne perennial ryegrass L. perene & L.multiflorum perennial shorter, to 90 cm. 20cm. 7-9 florets by Joe DiTomaso by Arieh Tal L. multiflorum Italian ryegrass biennial; taller and more robust to 127 cm; 30cm.; 10-20 florets; Duration Plant height Inflorescence Spikelets Perennial ryegrass is used as a forage grass high yielding high quality and digestibility persistent under a grazing Turf grass fastest establishing species Uses By DLF By DLF By DLF Italian ryegrass is mainly used to produce hay and silage or as cover crops during winter to avoid soil erosion By DLF By DLF -Genome size: 2.6 Gbp (1C) 2.3 Gbp in 7 chromosomes; 243.81 Mbp in 9135 no-chr scaffolds; 50.000 genes Genome - Reproduces by seed or asexually with new tillers - Conserved synteny to barley, brachypodium, rice, and sorghum -Diploid species (2n=2x=14) -chromosome doubling using colchicine treatment -tetraploid varieties are more winter hardy, rust-resistant, and more palatable when compared to diploid varieties Kingdom: Fungi Division: Basidiomycota Family: Pucciniaceae Obligate and biotrophic parasites Puccinia Sexual and asexual reproduction Autoecious or heteroecious Crown rust Puccinia coronata Crown rust Elongated yellowish pustules; Breaks on the leaf surface; Increased transpiration water loss; Reduce plant vigor; Reduce quality and yield of ryegrass; is the causal agent of crown rust on a wide range of grass species in the genera of Avena, Festuca, Hordeum, Lolium, and Poa. teliospores Brown rust P. loliina Stem rust P. graminis The disease occurs in spring and early summer; Oval-shaped orange spores; Affect perennial ryegrass seed production; Occurs in stems and leaves; Brick-red uredinospores and develops in black teliospores; Brown & stem rust Disease management Disease management Types of resistance PATHOGEN conditions favoring virulence Mechanism of resistance HOST conditions favoring susceptibility Disease severity ENVIRONMENT conditions favoring disease Apparent Resistance True Resistance Non-Host Resistance Disease Escape Tolerance to disease True resistance when the pathogen and its host are more or less incompatible, either because of lack of chemical recognition or because the host plant can defend itself against the pathogen. Plants developed two layers of immunity to protect themselves from pathogen attack: PAMP-triggered immunity (PTI) Effector-triggered immunity (ETI) Quantitative resistance Involve several genes associated with quantitative trait loci (QTL) Confer partial level of resistance to the plant non-race specific The response is controlled by multiple minor resistance genes (polygenic resistance): peroxidase, oxidase, chitinase, wrkt etc. Quantitative resistance Race- specific resistance Gene-for-gene resistance The response is controlled by one or few R genes, resulting in hypersensitive response. To suppress the plant defense mechanisms, pathogens need to produce new and different effectors to avoid the receptor activation. TRADITIONAL BREEDING Recurrent phenotypic selection; Pedigree and progeny information; Limited number of parental lines selected for their general combining ability; Breeding strategies AIM: to obtain a homozygous population for major resistance genes; PROBLEM: long process, loss of rare alleles, reduction of chances for selection; Molecular Markers Singular Nucleotide Polymorphism Molecular breeding Marker-Assisted Selection Select superior genotypes: agronomic traits: yield, height, protein quality, flowering time; abiotic stress resistance; biotic stress resistance; Next-Generation Sequencing GWAS to detect DNA regions associated with a complex trait GWAS Linkage Disequilibrium (LD): tendency of alleles to be transmitted together more or less often than expected by chance alone gene 1 SNP 1 Associated SNPs can be used in breeding programs to ensure that the obtained plant variety is resistant to the pathogen = resistance to the pathogen Genomic prediction an approach to predict the best individuals based on genetic values Genomic prediction TRAINING POPULATION y = Xb + Zu + e --> ----> TESTING POPULATION ----> STATISTICAL MODEL Make prediction on the TST for selection Genotype by Environmental Interaction (GxE) GxE is when different genotypes respond to environmental variation in different ways.
