Integrating skills profiling and purchasing portfolio management:an opportunity for building purchasing capability

Kralijc’s (1983) purchasing portfolio approach holds that different types of purchases need different sourcing strategies, underpinned by distinct sets of resources and practices. The approach is widely deployed in business and extensively researched, and yet little research has been conducted on how knowledge and skills vary across a portfolio of purchases. This study extends the body of knowledge on purchasing portfolio management, and its application in the strategic development of purchasing in an organization, and on human resource management in the purchasing function. A novel approach to profiling purchasing skills is proposed, which is well suited to dynamic environments which require flexibility. In a survey, experienced purchasing personnel described a specific purchase and profiled the skills required for effective performance in purchasing that item. Purchases were categorized according to their importance to the organization (internally-oriented evaluation of cost and production factors) and to the supply market (externally-oriented evaluation of commercial risk and uncertainty). Through cluster analysis three key types of purchase situations were identified. The skills required for effective purchasing vary significantly across the three clusters (for 22 skills, p<0.01). Prior research shows that global organizations use the purchasing portfolio approach to develop sourcing strategies, but also aggregate analyses to inform the design of purchasing arrangements (local vs global) and to develop their improvement plans. Such organizations would also benefit from profiling skills by purchase type. We demonstrate how the survey can be adapted to provide a management tool for global firms seeking to improve procurement capability, flexibility and performance

Exploring modifiable risk factors for premature birth in the context of COVID-19 mitigation measures: A discussion paper

The negative short-term impact on neonatal care in relation to the prevention of close proximity, contact and bonding between parents and babies is potentially significant. However, an interesting finding has been reported of a reduction in premature birth admissions to the neonatal intensive care unit during the pandemic, raising important questions. Why was this? Was it related to the effect of the modifiable risk-factors for premature birth? This discussion paper focuses on an exploration of these factors in the light of the potential impact of COVID-19 restrictions on neonatal care. After contextualising both the effect of premature birth and the pandemic on neonatal and parental short-term outcomes, the discussion turns to the modifiable risk-factors for premature birth and makes recommendations relevant to the education, advice and care given to expectant mothers.Peer reviewe

Long-Term Effects of the Periconception Period on Embryo Epigenetic Profile and Phenotype: The Role of Stress and How This Effect Is Mediated

Stress represents an unavoidable aspect of human life, and pathologies associated with dysregulation of stress mechanisms - particularly psychiatric disorders - represent a significant global health problem. While it has long been observed that levels of stress experienced in the periconception period may greatly affect the offspring's risk of psychiatric disorders, the mechanisms underlying these associations are not yet comprehensively understood. In order to address this question, this chapter will take a 'top-down' approach, by first defining stress and associated concepts, before exploring the mechanistic basis of the stress response in the form of the hypothalamic-pituitary-adrenal (HPA) axis, and how dysregulation of the HPA axis can impede our mental and physical health, primarily via imbalances in glucocorticoids (GCs) and their corresponding receptors (GRs) in the brain. The current extent of knowledge pertaining to the impact of stress on developmental programming and epigenetic inheritance is then extensively discussed, including the role of chromatin remodelling associated with specific HPA axis-related genes and the possible role of regulatory RNAs as messengers of environmental stress both in the intrauterine environment and across the germ line. Furthering our understanding of the role of stress on embryonic development is crucial if we are to increase our predictive power of disease risk and devise-effective treatments and intervention strategies

How age, sex and genotype shape the stress response

Exposure to chronic stress is a leading pre-disposing factor for several neuropsychiatric disorders as it often leads to maladaptive responses. The response to stressful events is heterogeneous, underpinning a wide spectrum of distinct changes amongst stress-exposed individuals'. Several factors can underlie a different perception to stressors and the setting of distinct coping strategies that will lead to individual differences on the susceptibility/resistance to stress. Beyond the factors related to the stressor itself, such as intensity, duration or predictability, there are factors intrinsic to the individuals that are relevant to shape the stress response, such as age, sex and genetics. In this review, we examine the contribution of such intrinsic factors to the modulation of the stress response based on experimental rodent models of response to stress and discuss to what extent that knowledge can be potentially translated to humans.FEDER through the Operational Programme Competitiveness Factors - COMPETE and National Funds through FCT - Foundation for Science and Technology under the project POCI-01-0145-FEDER-007038; and by the project NORTE-01-0145-FEDER-000013, supported by Norte Portugal Regional Operational Programme (NORTE, 2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF).

Blood-and Injection Phobia in Pregnancy : Epidemiological, Biological and Treatment aspects

Introduction: Blood- and injection phobia is an anxiety disorder with a prevalence of approximately 3-5% in the general population. The etiology is often a combination of genetic factors and a conditioning experience. The symptoms of blood- and injection phobia are dizziness, confusion, nausea, epigastria discomfort, anxiety and sometimes panic attacks when receiving injections, seeing blood or having a blood sample taken. Unique for this specific phobia is the high probability of fainting when the phobic situation is encountered if there is no possibility to escape or to avoid the stimuli. During pregnancy and labor, women with blood- and injection phobia are exposed to most of their fears and they therefore find themselves in anxiety-ridden situations. Stress and anxiety during pregnancy is known to be risk factors for adverse obstetric and neonatal outcomes. Studies have shown an altered hypothalamic-adrenal-pituitary axis in women with stress or/and anxiety during pregnancy and increased cortisol concentrations can imply negative consequences for the unborn child. Cognitive behavioral therapy (CBT) is known to be effective in treating specific phobias such as blood- and injection phobia. Aim: The prevalence, obstetric and neonatal consequences, impact on the hypothalamic adrenal-pituitary axis and treatment aspects of blood- and injection phobia in a pregnant population have not been investigated before. The aims of this thesis were to study each of these phenomena. Material and methods: During 2005 a total of 1606 pregnant women were approached at their first visit in an antenatal care clinic in the southeast region in Sweden. They were asked to complete the “Injection Phobia Scale-Anxiety” questionnaire. All women who scored ≥ 20 on the “Injection Phobia Scale-Anxiety” questionnaire (N=347), were interviewed and either diagnosed for blood- and injection phobia or dismissed. In total, 110 women were diagnosed as having blood- and injection phobia. Among the women who scored &lt;20 on the “Injection Phobia Scale-Anxiety” questionnaire, 220 women were randomly stratified for age and parity as a control group. The women in the study population answered questionnaires in gestational week 25, 36 and postpartum concerning symptoms of blood- and injection phobia, depression and anxiety. Samples of cortisol in the saliva were collected in the morning and evening in gestational week 25 and 36 in both groups of pregnant women. The medical records from the antenatal care visits, the delivery and postpartum check-up was used to collect data of importance. A treatment study was conducted using a two session cognitive behavioral therapy in a group of pregnant woman with blood- and injection phobia. Results: The prevalence of blood- and injection phobia is 7 % in a pregnant population. Pregnant women with blood- and injection phobia stated more often a fear of childbirth (p&lt;0.001) and were more frequently delivered by elective cesarean section (p=0.032). The incidence of having a baby diagnosed with a complication (p=0.001) was also higher among these women. The women with blood- and injection phobia had increased cortisol concentrations in the saliva compared to the healthy controls (p=0.014). A two-session CBT in group for pregnant women with blood- and injection phobia reduced phobic (p&lt;0.001) anxiety (p&lt;0.001) and depressive (p&lt;0.001) symptoms during pregnancy. Conclusions: Blood- and injection phobia during pregnancy is rather common. Pregnant women with blood- and injection phobia are more likely to be delivered by elective cesarean section and having a baby born with a complication compared to women not suffering from this specific phobia. Untreated blood- and injection phobia during pregnancy increases salivary cortisol concentrations indicating an altered hypothalamic-adrenal-pituitary axis during these weeks of pregnancy. To enhance psychological well being in pregnant women with blood- and injection phobia a two-session program providing CBT for groups of pregnant women is valuable and produces stable results for at least 3 months after delivery

An investigation of the targeted customers of a peer-to-peer car sharing company and how the company’s value proposition should be developed accordingly

Background and Purpose: Most countries in the world are becoming increasingly urbanized, which implies challenges related to transportation within cities. More individuals in cities, and hence more cars, has consequences such as increased congestion, limited parking space, as well as increased pollution. This means that there is a need for smarter and more sustainable ways of car usage. One potential solution to the problem is the practice of car sharing, or more specifically peer-to-peer (P2P) car sharing. A start-up company that has recognized the business opportunity related to P2P car sharing is Ciao Ciao Carsharing, which the researchers have collaborated with in this research. The company has realized that a deep understanding of its targeted customer segments is currently missing and believes that this understanding would enable them to better reach their targeted customers. The purpose of this research was therefore to obtain a deeper understanding of Ciao Ciao Carsharing’s targeted customers, as well as to investigate suggestions on how the company’s value proposition should be developed in order to create value for the targeted customers. Methodology: A combination of a qualitative and a quantitative research, referred to as a mixed research method, was used in this research. The research started with semi-structured interviews in order to gain a deeper understanding of the underlying motivations of each interviewee and thereby generate insights regarding the company’s targeted customer segments. A quantitative questionnaire was thereafter used in order to test whether the findings from the qualitative interviews were possible to generalize over a larger group of people. The findings that were generalizable were considered to be useful for the company as well as for the purpose of this research. Findings and Conclusions: The findings and conclusions include an overview of the most important factors that were found regarding the targeted customer segments, as well as suggestions on how the company should meet these. These suggestions include; the company should focus on (as well as invest in) what is most important for the targeted customers, they should create value together with the customers, as well as emphasize efficiency and utilitarian benefits rather than community building or sustainability concerns. It was further concluded that it is essential that the company meets the motives of both car owners and car renters, but also creates a match between the car owners and the car renters

Processutveckling för BAUHAUS WEB:s lager hanterat av PostNord TPL vid ökad kundorderhantering

PostNord TPL manages the warehouse for BAUHAUS WEB, which has expanded since the start in 2011. PostNord TPL face the challenge of handling articles with different characteristics from BAUHAUS WEB's wide product range. In consultation with BAUHAUS WEB, PostNord TPL believes that the number of customer orders will continue to increase. PostNord TPL now wants to prepare for the spring of 2021 by identifying process improvements and efficiency proposals for inventory management.  To understand the processes and identify the challenges within, a process mapping was done for the departments Delivery and Dispatch. Based on a workshop held during the thesis work, a need to relocate the items in the warehouse based on picking frequency was identified for Dispatch and a need for a correction for division of labor within Delivery. Division of labor concerns the activity logging of deliveries performed by a group leader.  The items picked at the warehouse are picked according to different picking lists based on customer orders that vary from day to day. By examining the design of a picking list, it was possible to investigate if an ABC-classification would make the picking process more efficient. For storage areas with one customer order per picking list, the analysis showed that an ABC-classification favored the inventory management.  The number of warehouse employees required to handle the increase in customer order during spring of 2021 was calculated with resource plans for Delivery and Dispatch. For the departments Delivery and Dispatch two resource plans each were made. The resource plan for Delivery considering logging of deliveries showed a marginal difference in number of employees. For Dispatch the resource plan considering the picking time reduction from the ABC-classification gave the least number of employees. PostNord TPL should carry out an ABC-classification to make the inventory management more efficient which contributes to fewer employees and affects the storage and refill of goods. A future study that this work can be followed up with, is to investigate whether and how the ABC-classification changes during the entire low season and the transition between high and low season.
