This paper describes the development and test of a novel LiDAR based combine harvester steering system using a harvest scenario and sensor point cloud simulation together with an established simulation toolchain for embedded software development. For a realistic sensor behavior simulation, considering the harvesting environment and the sensor mounting position, a phenomenological approach was chosen to build a multilayer LiDAR model at system level in Gazebo and ROS. A software-in-the-loop simulation of the mechatronic steering system was assembled by interfacing the commercial AppBase framework for point cloud processing and feature detection algorithms together with a machine model and control functions implemented in MATLAB/ Simulink. A test of ECUs in a hardware-in-the-loop simulation and as well as HMI elements in a driver-in-the-loop simulation was achieved by using CAN hardware interfaces and a CANoe based restbus simulation.
Work–life balance is one of the challenges of a globalized world. The study described in this chapter aimed to identify the factors influencing the work–life balance of working mothers. Additionally, we will describe differences and similarities between the well-being and working styles of German and US-American working mothers. It is particularly difficult for mothers to be successful, because to do so, they must master the double burden of work and family. In this study, 320 working mothers were surveyed, 142 in Germany and 178 in the USA. It was found that the cultural concepts of work–life balance of these working mothers are comparable. Furthermore, differences in working styles were identified: US-Americans valued both well-being and work–life balance more strongly than Germans. In both cultures, younger mothers felt more burdened by work than older mothers. This may indicate that competences are learned with an increasing age, enabling a more successful mastery of challenges, even though an increasing age usually has a negative effect on health. The number of children, family status and education did not influence work–life balance. These findings are further discussed in this chapter.
Talent scarcity in many parts of the world leads to the necessity to enlarge talent pools in order to provide enough future holders of key positions. Taking the scholarly discussion at the overlap of talent management and current careers literature as a starting point our qualitative empirical research provides insights in talent’s career decisions in an eastern emerging market, India, and a western developed country, Germany. 49 interviews with internationally experienced knowledge-workers were held to find out how to they come to career decisions throughout their career. Special focus was the balancing act of professional and private life sphere. An inductive-deductive approach was used to develop categories in MaxQda. Results show the impact of institutional frame, cultural context, and gender differences. Consequently, a stronger focus on talent’s different life phases with context specific deviations when configuring Talent Management in Multinational Enterprises can be advised.
Background
To offer vaginal birth after cesarean (VBAC) in a hospital setting is recommended in international guidelines, but offering VBAC in out‐of‐hospital settings is considered controversial. This study describes neonatal and maternal outcomes in mothers who started labor in German out‐of‐hospital settings.
Method
In a retrospective analysis of German out‐of‐hospital data from 2005 to 2011, included were 24,545 parae II with a singleton pregnancy in a cephalic presentation at term (1,927 with a prior cesarean and 22,618 with a prior vaginal birth).
Result
The overall VBAC rate was 77.8 percent. The intrapartum transfer rate to hospital was 38.3 percent (prior cesarean) versus 4.6 percent (prior vaginal) (p < 0.05), and the 10‐minute Apgar < 7 rate was 0.6 versus 0.2 percent (p < 0.05), and the nonemergency intrapartum transfer rate was 91.5 versus 85.0 percent (p < 0.05). Prolonged first stage of labor was the most common reason for intrapartum transfer in both groups. The leading reason for postpartum transfer was retained placenta.
Discussion
There was a high rate of successful VBAC in this study. The high nonemergency transfer rate for women with VBAC might mean that midwives are more cautious when attending women with a prior cesarean in out‐of‐hospital settings. Further studies are necessary to evaluate which women are suitable for VBAC in out‐of‐hospital settings.
This paper introduces and empirically illustrates a pedagogical approach to teaching Public Relations (PR) in higher education. The approach is based on the Communities of Practice theory (Wenger, 1998). Based on this theory and for the purposes of this paper, learning is perceived as (1) a participation in a practice of (2) a social community and (3) the understanding of this practice. The pedagogical approach to teaching PR entails the facilitation of these three elements. The approach is illustrated through a case study. The authors conducted an international undergraduate course to teach students how to conduct a social media campaign to raise engagement for social issues. Twenty students from Netherlands and Germany enrolled. The paper offers an integrated understanding of theory and practice (see Wenger, 1998, p. 48). It contrasts many current approaches in PR education, which tend to differentiate between PR theory and practice. PR educators are encouraged to facilitate an equal negotiation between theory and practice and to enable students to match whatever is theorised with practice and whatever is practiced with theory.
The Internet of Things (IoT) relies on sensor devices to measure real-world phenomena in order to provide IoT services. The sensor readings are shared with multiple entities, such as IoT services, other IoT devices or other third parties. The collected data may be sensitive and include personal information. To protect the privacy of the users, the data needs to be protected through an encryption algorithm. For sharing cryptographic cipher-texts with a group of users Attribute-Based Encryption (ABE) is well suited, as it does not require to create group keys. However, the creation of ABE cipher-texts is slow when executed on resource constraint devices, such as IoT sensors. In this paper, we present a modification of an ABE scheme, which not only allows to encrypt data efficiently using ABE, but also reduces the size of the cipher-text, that must be transmitted by the sensor. We also show how our modification can be used to realise an instantaneous key revocation mechanism.
Semi-solid metal alloys, as used in thixoforming, have a special microstructure of globular grains suspended in a liquid metal matrix. The complex rheological properties are strongly influenced by the local solid fraction, particle shape, particle size and state of agglomeration. There is a high demand for models and software tools allowing the simulation of semi-solid casting processes. The material under investigation is a tin-lead alloy (Sn-15%Pb) which exhibits a similar microstructure to aluminium alloys. The experiments were performed with a concentric cylinder rheometer of the Searle type. Initially, the liquid alloy is cooled down to the semi-solid range under constant shearing and then kept under isothermal conditions for further experimentation. Based on the experimental data, a single-phase model has been derived where the semi-solid alloy is regarded as a homogeneous material with thixotropic properties and the microstructure is characterised by a structural parameter. The model consists of two parts: the equation of state, including a finite yield stress, and a rate equation for the structural parameter. The model equations are employed in numerical software and used for the simulation of characteristic filling cases and the comparison with the conventional filling.
Teachers in health informatics have a broad variety of international and national educational recommendations to rely on when designing programmes, curricula, courses and educational material. However, in addition they often need very specific information for their setting, blue-prints, hands-on experience and encouragement to try something new. This workshop presents three case studies from European universities who have implemented inter-professional, technology enabled health informatics courses in undergraduate, postgraduate and open university settings. These approaches will be put into the context of the TIGER recommendation framework that includes priority ratings of health informatics competencies and case studies to illustrate them. The workshop attendees will have ample opportunity to exchange ideas with the presenters and start a mutual learning process for health informatics teachers.
Background: Muscle fatigue has been reported as a risk factor for the
development of performance-related musculoskeletal disorders (PRMD) in
musicians. However, little research exists to support this claim. The aim of
this study was to investigate whether changes occur in muscle activity
patterns during high string performance over a prolonged playing period, and
whether this is influenced by PRMD.
Methods: High string musicians were divided into a PRMD and a non-PRMD
group. They played a chromatic scale pre and post and a self-chosen “hard”
(Borg scale 16-17) piece of music for one hour. Electromyography data
recorded from arm, shoulder and trunk muscles was analyzed: the amplitude
to measure muscle activity characteristics and the lower frequency to
measure muscle fatigue. Differences between and within groups and the
frequency spectrum were analyzed using linear mixed models.
Results: Fifteen musicians participated (7 PRMD: 22.8 years, 2 male/5 female
and 8 non-PRMD: 34.3 years, 2 male/6 female). Changes in muscle activation
patterns were observed between and within both groups, however changes
varied significantly depending on group affiliation. Significant low frequency
spectrum changes between groups were observed in overall muscles of the
right arm (p=0.04) and left forearm flexors (p=0.05) following one hour of
playing.
Conclusions: Muscle activity and frequency spectrum shifts differ in high
string musicians with and without PRMD, suggesting possible differential
muscle fatigue effects between the groups.
This review gives an overview about the existing research concerning siblings' perspective within the familial experiences of childhood chronic illness. Besides attaining a conception of their world, it was intended to identify the unacknowledged issues concerning siblings' experience. Four databases were systematically searched. The analysis was concentrated on nine literature reviews. As a result, we identified a map of dimensions of experiences—well-elaborated as well as fragmentary. Many of the studies were conducted by a proxy and not from the sole siblings' perspective. Further research should concentrate on the sole siblings' perspective, in order to make siblings' voices audible.
Objective: to understand the meaning of the Adult Intensive Care Unit environment of care,
experienced by professionals working in this unit, managers, patients, families and professional
support services, as well as build a theoretical model about the Adult Intensive Care Unit
environment of care. Method: Grounded Theory, both for the collection and for data analysis.
Based on theoretical sampling, we carried out 39 in-depth interviews semi-structured from
three different Adult Intensive Care Units. Results: built up the so-called substantive theory
“Sustaining life in the complex environment of care in the Intensive Care Unit”. It was bounded
by eight categories: “caring and continuously monitoring the patient” and “using appropriate
and differentiated technology” (causal conditions); “Providing a suitable environment” and
“having relatives with concern” (context); “Mediating facilities and difficulties” (intervenienting
conditions); “Organizing the environment and managing the dynamics of the unit” (strategy)
and “finding it difficult to accept and deal with death” (consequences). Conclusion: confirmed
the thesis that “the care environment in the Intensive Care Unit is a living environment, dynamic
and complex that sustains the life of her hospitalized patients”.
In idea creation and assessment processes the accruement and the description of an idea are mostly allocated to a fixed point in time, defined as the end of the generating process and the start of the idea assessment. This static approach does not fit the reality in industrial idea processes. A dynamic approach for idea assessment is therefore introduced. An idea is not seen as a static but as a dynamic state, characterized by different degrees of maturity. Maturity is understood as a measure of the assessability of the individual evaluation characteristics.
Based on Crosby’s maturity model and on classical Capability Maturity Models, a new Idea Maturity Model (IMM) has been developed and is introduced for the first time. The five Idea Maturity Levels (IML) are named Initial, Awareness, Appraisability, Valuation, and Realisability and harmonize well with other maturity models. The levels are described by general characteristics, although the development of the maturity model focussed on new product or service development. The compatibility of the IMM with idea assessment processes and conditions in organisations and companies has been checked.
Background
The continuous rise in caesarean rates across most European countries raises multiple concerns. One factor in this development might be the type of care women receive during childbirth. ‘Supportive care during labour’ by midwives could be an important factor for reducing fear, tension and pain and decreasing caesarean rates. The presence and availability of midwives to support a woman in line with her needs are central aspects for ‘supportive care during labour’.
To date, there is no existing research on the influence of effective ‘supportive care’ by German midwives on the mode of birth. This study examines the association between the attendance and workload of midwives with the mode of birth outcomes in a population of low-risk women in a German multicentre sample.
Methods
The data are based on a prospective controlled multicentre trial (n = 1,238) in which the intervention ‘midwife-led care’ was introduced. Four German hospitals participated between 2007 and 2009.
Secondary analyses included a convenience sample of 999 low-risk women from the primary analyses who met the selection criterion ‘low-risk status’. Participation was voluntary. The association between the mode of birth and the key variables ‘attendance of midwives’ and ‘workload of midwives’ was assessed using backward logistic regression models.
Results
The overall rate of spontaneous delivery was 80.7% (n = 763). The ‘attendance of midwives’ and the ‘workload of midwives’ did not exhibit a significant association with the mode of birth. However, women who were not satisfied with the presence of midwives (OR: 2.45, 95% CI 1.54-3.95) or who did not receive supportive procedures by midwives (OR: 3.01, 95% CI 1.50-6.05) were significantly more likely to experience operative delivery or a caesarean. Further explanatory variables include the type of hospital, participation in childbirth preparation class, length of stay from admission to birth, oxytocin usage and parity.
Conclusion
Satisfaction with the presence of and supportive procedures by midwives are associated with the mode of birth. The presence and behaviour of midwives should suit the woman’s expectations and fulfil her needs. For reasons of causality, we would recommend experimental or quasi-experimental research that would exceed the explorative character of this study.
The increasing complexity of caseloads in SLT practice, e.g. due to higher comorbidity, lacking information or experience in the
treatment of complicated cases, calls for support from experienced as well as specialist practitioners from within the field - especially
for novice therapists. One way to tackle these challenges may be peer coaching and how it can be employed within the educational
and professional SLT setting.
Peer coaching was implemented across five semesters of a successive SLT study programme at a University of Applied Sciences in
Germany. The approach was embedded in a clinical reasoning seminar with 25 SLT students who each presented a challenging case
study from their current workload. All participants completed a short online survey to evaluate the feasibility of the team approach
within this setting as well as their personal benefit and development re. the discussed case studies.
Students felt encouraged by being able to share their experience and tackle actual challenges. They particularly valued receiving
answers from a broad range of other SLTs but also contributing to other students’ queries and providing practical solutions for
them. All participants felt that peer coaching was an appropriate approach for clinical reasoning to support their professional as well
as personal development. Other outcomes were a perceived increased ability to employ metacognitive reflection to be used with
their whole caseload but also a prospective need for further training. Some students suggested the employment of peer coaching
within their work setting.
In the educational as well as professional SLT setting, peer coaching can be successfully employed, triggering metacognitive
reflection re. practitioner’s thinking and acting, resulting in an increased awareness of needs and skills as part of the clinical
reasoning process.

Still Searching or Have You Found It Already? – Usability and Web Design of an Educational Website
(2018)
Background: Apart from a straight-forward and intuitive operability an appealing design determines the success of a website equally well. For this reason, the selection of images and navigation bars plays a determining role. The eye tracking method proved to be appropriate in order to verify the usability of websites. Objectives: The aim of the study was to improve the usability of the website of an educational institute for trainees as target group. Methods/Approach: For this purpose, the use of an eye-tracking technology was combined with a survey. The eye-tracking study was implemented task-oriented. Test persons were asked to search for particular courses within this institute. Results: This approach in combination with a subsequent questionnaire resulted in tangible indications of search patterns of the test group. Furthermore, their perception and their appraisal of the usability as well as the web design was analysed. Even though most tasks were accomplished effectively and efficiently with a positive user feedback, a potential for improvement was detected, in particular with regard to the images and the location of the search field. Conclusions: The selected choice of methods enables researchers and web designers to derive recommendations for the orientation, structure, optimisation and comprehensibility of a website.
Despite normal neurological bedside and electrodiagnostic, some patients with non-specific neck arm pain (NSNAP) have heightened nerve mechanosensitivity upon neurodynamic testing [1, 2]. It remains however unclear whether this is associated with a minor nerve injury. The aim of this study was to evaluate potential differences in somatosensory function among patients with unilateral NSNAP with and without positive neurodynamic tests and healthy controls.
Quantitative sensory testing was performed in 40 patients with unilateral NSNAP; 23 with positive upper limb neurodynamic tests (ULNTPOS) and 17 with negative neurodynamic tests (ULNTNEG). The protocol comprised thermal and mechanical detection and pain thresholds as well as mechanical pain sensitivity, wind-up ratio and dynamic mechanical allodynia. All parameters were measured in the maximal pain area on the affected side as well as over the corresponding area on the unaffected side. Symptom severity, functional deficits, psychological parameters, quality of life and sleep disturbance were also recorded.
Fifty-seven percent of patients with NSNAP had positive neurodynamic tests despite normal bedside neurological integrity tests and nerve conduction parameters. Clinical profiles did not differ between patient groups. Somatosensory profiling revealed a more pronounced loss of function phenotype in ULNTPOS patients compared to healthy controls. Hyperalgesia (cold, heat and pressure pain) was present bilaterally in both NSNAP group. The ULNTNEG subgroup represented an intermediate phenotype between ULNTPOS patients and healthy controls in both thermal and pressure pain thresholds as well as mechanical detection thresholds.
In conclusion, heightened nerve mechanosensitivity was present in over half of patients with NSNAP. Our data suggest that NSNAP presents as a spectrum with some patients showing signs suggestive of a minor nerve dysfunction.

Social determinants of health that influence the healthy living process in a vulnerable community
(2016)
Background
Forced migration significantly endangers health. Women face numerous health risks, including sexual violence, lack of contraception, sexually transmitted disease, and adverse perinatal outcomes. Therefore, sexual and reproductive healthcare is a significant aspect of women asylum seekers’ health.
Even when healthcare costs of asylum seekers are covered by the government, there may be strong barriers to healthcare access and specific needs may be addressed inadequately. The study’s objectives were a) to assess the accommodation and healthcare services provided to women asylum seekers in standard and specialised health care, b) to assess the organisation of healthcare provision and how it addresses the sexual and reproductive healthcare needs of women asylum seekers.
Methods
The study utilised a multi-method approach, comprising a less-dominant quantitative component and dominant qualitative component. The quantitative component assessed accommodation conditions for women in eight asylum centres using a survey. The qualitative component assessed healthcare provision on-site, using semi-structured interviews with health and social care professionals (n = 9). Asylum centres were selected to cover a wide range of characteristics. Interview analysis was guided by thematic analysis.
Results
The accommodation in the asylum centres provided gender-separate rooms and sanitary infrastructure. Two models of healthcare were identified, which differed in the services they provided and in their organisation: 1) a standard healthcare model characterised by a lack of coordination between healthcare providers, unavailability of essential services such as interpreters, and fragmented healthcare, and 2) a specialised healthcare model specifically tailored to the needs of asylum-seekers. Its organisation is characterised by a network of closely collaborating health professionals. It provided essential services not present in the standard model. We recommend the specialised healthcare model as a guideline for best practise.
Conclusions
The standard, non-specialised healthcare model used in some regions in Switzerland does not fully meet the healthcare needs of women asylum seekers. Specialised healthcare services used in other regions, which include translation services as well as gender and culturally sensitive care, are better suited to address these needs. More widespread use of this model would contribute significantly toward protecting the sexual and reproductive integrity and health of women asylum seekers.
Scientific Entrepreneurship: Raising A wareness of Entrepreneurship - Strategies ans Experiences
(2011)
Niche-based species distribution models (SDMs) play a central role in studying species response to environmental change. Effective management and conservation plans for freshwater ecosystems require SDMs that accommodate hierarchical catchment ordering and provide clarity on the performance of such models across multiple scales. The scale-dependence components considered here are: (a) environment spatial structure, represented by hierarchical catchment ordering following the Strahler system; (b) analysis grain, that included 1st to 5th order catchments; and (c) response grain, the grain at which species respond most, represented by local and upstream catchment area effects. We used fish occurrence data from the Danube River Basin and various factors representing climate, land cover and anthropogenic pressures. Our results indicate that the choice of response grain – local vs. upstream area effects – and the choice of analysis grain, only marginally influence the performance of SDMs. Upstream effects tend to better predict fish distributions than corresponding local effects for anthropogenic and land cover factors, in particular for species sensitive to pollution. Key predictors and their relative importance are scale and species dependent. Consequently, choosing proper species dependent spatial scales and factors is imperative for effective river rehabilitation measures.
Management of agricultural processes is often troubled by disconnections and data transfer failures. Limited cellular network coverage may prevent information exchange between mobile process participants.
The research projects KOMOBAR and ISOCom designed, implemented und field-tested a delay tolerant platform for robust communication in rural areas and challenging environments. An adaptable combination of infrastructure-based cellular networks and infrastructure-free multihop ad hoc communication (WLAN) leads to a variety of new communication opportunities. Temporal storage and forwarding of data on mobile farm machinery as well as dynamic platform configurations during process runtime strongly enhance reliability and robustness of data transfers.
We describe an automated approach, to easily track patients regaining their walking ability while recovering from neurological diseases like e.g. stroke. Based on captured gait data and objective measures derived out of it the rehabilitation process can be optimized and thus steered. In order to apply such system in clinical practice two key requirements have to be fulfilled: (i) the system needs to be applicable in terms of ease of use and performance; (ii) the derived measures need to be accurate.
Rationale:
Dance as an intense kind of performance is associated with high loads on the musculoskeletal system. In particular, the lower limb is exposed to these high loads, which is reported by a high prevalence. Most dancers are affected by injuries during their careers, most in the lower limb. Typical risk factors for dancers include the compensatory turnout, hypermobility, and core stability. The correlation between these factors and lower limb injuries is not fully understood.
Purpose:
The aim of this study was to evaluate the correlation between lower limb injuries and the risk factors compensated turnout, hypermobility and core stability. Based on these results, hypotheses can be generated for further studies.
Methods:
This explorative pilot study was conducted at Osnabrück University of Applied Sciences. All eligible participants were scheduled for a single research appointment if they fulfilled the inclusion criteria of dance experience (ballet, modern, contemporary or jazz) at least one year with dance lessons of at least 5 hours per week. Parameters for the correlation analysis were (1) core stability, measured by the motor control tests battery proposed by Luomajoki, (2) hypermobility, measured by the Beighton Score (3) compensated turnout, measured by the difference between functional turnout and external rotation of both hips, (4) dance hours per week, (5) dance experience in years, (6) professional dance experience in years and (7) dance style (ballet, modern, contemporary, jazz). These parameters were correlated with the numbers of lower limb injuries. Significance level was set at 90% because of the explorative character of the study with the purpose to generate hypotheses.
Results:
Sixteen female dancers with different levels of dance experience (mean 11.3 years) and dance lessons per week (mean 17.6 hours) fulfilled the inclusion criteria and participated in this study. Significant correlations with the numbers of lower limb injuries were found at core stability (rs=0.489, p=0.034, medium effect), dance hours per week (rs=0.459, p=0.048, medium effect) and professional dance experience in years (rs=0.396, p=0.093, medium effect). Two dance styles (modern dance: rs=0.388, p=0.101 and contemporary dance: rs=0.385, p=0.104) were close to the significance level.
Conclusions:
These results show correlations between core stability, dance hours per week, professional dance experience in years and lower limb injuries in dancers.
Due to the limitations of a small and heterogeneous sample size as well as the medium effects, these results should be interpreted with caution, but may provide a basis for further research to this topic in the field of dance research and can be helpful in generating research hypotheses.
Semi-solid metal alloys, as used in thixoforming, have a special microstructure of globular grains suspended in a liquid metal matrix. The material under investigation is a tin–lead alloy (Sn–15% Pb) which exhibits a similar microstructure as aluminum alloys. The experiments were performed with concentric cylinder rheometers. Initially, the liquid alloy is cooled down to the semi-solid range under constant shearing and then kept under isothermal conditions for further experimentation. The microstructure is characterized in dependence of the shearing time. The rheological techniques consisted of step change of shear rate and shear stress ramp experiments for different solid fractions (40–50%). Based on the experimental data a single phase model has been derived, where the semi-solid alloy is regarded as a homogeneous material with thixotropic properties and the microstructure is characterized by a structural parameter. The model consists of two parts: the equation of state, including a finite yield stress, and a rate equation for the structural parameter. The model equations are employed into numerical software and used for the simulation of a characteristic thixocasting process. The results are compared to real experiments.
Relationship of QST measures between low back and leg sites in people with radicular leg pain
(2019)
Background and Aims
Clinicians and researchers often rely on altered neurological integrity tests in the leg to identify radicular pain, however neurological integrity is often not tested in the low back region even in the presence of pain in this region. There have been suggestions that the low back pain itself could be neuropathic in nature in some patients (Baron et al., 2016). This study aims to explore the relationship between quantitative sensory testing (QST) measures in the leg and low back in participants with radicular leg pain to consider if sensory testing should be performed in both areas in clinical practice.
Methods
13 participants (mean age 48.2 SD 13.8, gender (female) 8) with radicular leg pain were recruited from National Health Service spinal clinics in the UK. After assessment with the clinician, a full QST profile was taken from each participant’s affected leg and low back. Z scores were calculated using data from age matched healthy controls. Correlations using Pearson’s if the data was normally distributed or Kendall’s Tau-b if not, were undertaken between QST scores of the low back and leg. Paired t tests or Mann Whitney tests were performed to assess differences in QST scores between the leg and low back regions.
Results
There were no significant correlations (P>0.05) in any of the QST measures between the leg and the low back regions. However, only vibration detection threshold measures showed statistically significant differences between the leg and low back (p<0.001), with the low back region showing greater loss of function (mean -2.84) than the leg (mean -0.61).
Conclusions
Significantly lower vibration thresholds were found in the back compared to the leg. This may suggest some alteration in posterior primary ramus large diameter afferent nerve function, and indicate that the low back pain itself may indeed have a neuropathic component. Our findings suggest that sensory testing of the lumbar spine may be advisable in this group of individuals. The small sample size means that these results must be taken with some caution, however these results warrant further investigation in people with radicular leg pain.
Talent scarcity in emerging economies such as India poses challenges for companies. Limited labour market participation among well-educated women has been observed. The reasons that professionals decide not to pursue a further corporate career remain unclear. By investigating their career decision making, this handout summerizes research results from a study that aims to highlight the contextual factors that impact those decisions.
Following a qualitative research design interviews with internationally experienced Indian business professionals show that rebellion against Indian societal and family expectations is essential to following a career path, especially for women. The current institutional framework of society and organizations serves as a legitimizing façade veiling traditional practices that hinder females’ careers.
Protection and privacy of data in cooperative agricultural processes : the challenges of the future
(2016)
In agriculture, the growing usage of sensors, smart mobile machinery and information systems results in high volumes of data. The data differs in accuracy, frequency, volume, type and, most importantly, owner of the information. However, cooperative processes and big data analyses require access to comprehensive amounts of data for successful agricultural operation and reasoning. In some processes instructed contractors even gather data belonging to other owners and use it for machinery operation optimisation and accounting (e.g. yield in maize harvest). Today’s approach of data handling has a high potential to conflict with European and national regulations for data protection and privacy. This article presents a concept for continuous data protection and privacy in cooperative agricultural processes. The concept aims at ensuring data sovereignty for the owner while making as much data usable for process operation and big data research at the same time. Briefly explained, owners pick a collection of data and create usage licenses for other players. The licenses specify time-limited and / or position-bound access to the data collection. Privacy environments in soft- and / or hardware protect access rights on end user devices, data share hubs and machinery devices such as agricultural terminals. In addition to access right configurations, digital signatures prevent data manipulation when cooperative players capture data during processes. Socalled signature boxes represent certificated soft- or hardware components, which are located close at data sources (e.g. as hardware attached to sensors on mobile machinery) and bind the data captured with digital signatures.
The global climate system is currently warming due to the increase in CO2 emissions caused by humans. Technically oriented efficiency strategies are seen more frequently as solutions to reach the European Union’s maximum two degrees Celsius target. Companies play an important role in limiting climate change and must either prepare for such consequences or adopt new strategies such as the sufficiency strategy.
This article will discuss how the sufficiency strategy and the promotion of sufficient living in the context of the tourism industry can contribute to reducing CO2 emissions. Most common approaches toward sufficient living found in literature will be identified, analysed and discussed. Based on chosen keywords, the most common approaches were identified through a literature review of relevant journals from 1989 to 2014. Four main research fields that can promote sufficient living and reduce CO2 emissions were identified. Based on the prospects of the companies, it is apparent that sufficient strategies are not only able to support a market-orientated corporate management but also promote sufficient living and thus reduce CO2 emissions.
The purpose of this study was to evaluate which mode of birth first-time mothers in Germany and in the USA prefer and how this desire is related to maternal well-being and sense of coherence. The paper describes emotional well-being postpartum in relationship to mode of birth. For data collection a prospective cohort study was conducted in both countries. A self-administered questionnaire including validated instruments (WHO-5 Well-Being Index, Sense of Coherence Scale and Edinburgh Postnatal Depression Scale) was used. Results showed that only a few of the pregnant women in Germany and the USA preferred to deliver by caesarean section. There was a relationship between women's well-being, women's sense of coherence and the preferred mode of birth. The majority of women who wanted a caesarean section delivered in this way. No relationship was found between women's well-being and the type of birth experienced. Well-being in both samples generally decreased after giving birth, but there was a difference between German and American first-time mothers on the postpartum well-being and depression scores. German mothers had a higher postnatal quality of life and lower postnatal depression scores. To give families the opportunity for a healthy start, midwives and obstetricians should try to enhance women's well-being and they should give some thought to health professionals' decision-making processes. Expanded postpartum care might have an impact on women's depression scores..
Introduction:
Due to demographic change and lack of health care personnel new solutions like preventive home visits (PHV) are necessary. PHV reduces the risk of long-term care and therefore, enables older people to live in their home as long as possible.
Aim of the study:
The aim of this study is to analyse the acceptance of PHV and the effect of PHV on health status of the older people.
Methods:
In this mixed method study PHV as a nursing intervention will be offered to people older than 65 years, not yet eligible for benefits from the long-term care insurance and living in Emlichheim, a region in the northwestern part of Lower Saxony. A sample of 75 people is determined. The health status will be recorded with the Short Form 12 questionnaire. Fifteen semi-structured interviews will be performed to investigate acceptance of the PHV intervention. Quantitative data will be analysed using inferential statistics, qualitative data will be analysed using content analysis. Ethical approval has been obtained.
Results:
It is expected that the findings of this study complete current knowledge about the concept of PHV.
Practical relevance:
This study is of high practical relevance, because additional insights of acceptance might enable the adaption of the PHV concept. Furthermore, increased knowledge and motivation for preventive behaviour of the older people is anticipated in order to extend their autonomy. The results of this study could contribute to the implementation of PHV in Germany, especially in rural areas. It tends to allow a self-determined life in their familiar environment for the older people, as the biggest need of this group.
This study investigates how microenterprises in Ethical Fashion (EF) retail adopt and make use of social media. Drawing on an explorative case study, supplemented by an action research approach, we first examine the antecedents of a successful Adoption based on the Technology-Organization-Environment (TOE) framework. Subsequently, we shed light on the benefits and drawbacks of social media adoption for the three microenterprises of our case study on the operational and the strategical level. More particularly, we present how they improve value creation through the employment of social media in their value networks and how they overcome the lack of a sophisticated IT infrastructure. Finally, we investigate the reluctance of the three microenterprises to adopt inter-organizational information systems. The findings of our study also reveal a halo effect in the adoption process that may mislead the adopting organization.
Optimised Nutrient Recovery from Biogas Digestate by Solid/Liquid Separation and Membrane Treatment
(2019)
Anaerobic digestion products of agricultural biogas plants are characterised by high nitrogen, phosphorus, and potassium content. In three scale-up steps, a membrane based digestate treatment process of solid-liquid-separation, ultrafiltration, and reverse osmosis for nutrient recovery was investigated. Lab-scale trials delivered a very good understanding of fluid properties and subsequent ultrafiltration performance, which is the limiting process step in terms of energy demand and operation costs. In semi-technical experiments, optimisation, and design parameters were developed, which were subsequently applied to pilot-scale tests at two full-scale biogas plants. The process optimisation resulted in 50 % energy reduction of the ultrafiltration step. About 36 % of the sludge volume was recovered as dischargeable water, 20 % as solid N/P-fertiliser, and 44 % as liquid N/K-fertiliser.
Biogas plants produce nutrient rich digestates as side products, which are usually used as local fertilisers. Yet the large amount and regional gradients of biogas plants in Germany necessitate management, conditioning, and transportation of digestates, in order to follow good fertilising procedure and prohibit local over-fertilisation. With a membrane-based treatment chain, i.e. centrifugation, ultrafiltration, and reverse osmosis, digestates can be separated into a solid N,P-fertiliser, a liquid N,K-fertiliser, and dischargeable water. Up to now, the high energy demand of the process chain, in particular the ultrafiltration step, limits the economical market launch of the treatment chain. A reduction of the energy demand is challenging, as digestates exhibit a high fouling potential and ultrafiltration fluxes differ considerably for digestates from different biogas plants. In a systematic screening of 28 digestate samples from agricultural biogas plants and 6 samples from bio-waste biogas plants, ultrafiltration performance could be successfully linked to the rheological properties of the digestate’s liquid phase and to its macromolecular biopolymer concentration. By modification of the fluid characteristics through enzymatic treatment, ultrafiltration performance was considerably increased by factor 2.8 on average, which equals energy savings in the ultrafiltration step of approximately 45%. Consequently, the energy demand of the total treatment chain decreases, which offers potential for further rollout of the membrane-based digestate treatment.
Pregnancy loss is the most common complication in pregnancy. Yet those who experience it can find it challenging to disclose this loss and feelings associated
with it, and to seek support for psychological and physical recovery. We describe our process for
interleaving interviews, theoretical development, speculative design, and prototyping Not Alone to
explore the design space for online disclosures and
support seeking in the pregnancy loss context.
Interviews with 27 women who had experienced pregnancy loss resulted in theoretical concepts such as
“network-level reciprocal disclosure” (NLRD). We discuss how interview findings informed the design of
the Not Alone prototype, a mobile application aimed at enabling disclosure and social support exchange among those with pregnancy loss experience. The Not Alone prototype embodies concepts that facilitate NLRD: perceptions of homophily, anonymity levels, and selfdisclosure by talking about one’s experience and engaging with others’ disclosures. In future work, we will use Not Alone as a technology probe for exploring
NLRD as a design principle.
As of the reporting year 2017, extended non-financial reporting requirements will apply to certain large companies within the EU on the basis of the EU-Directive 2014/95/EU. The aim is to provide an overview of selected regulations for the new non-financial statements. This includes the analysis of the German Sustainability Code as well as the German Accounting Standard No. 20. The analysis shows a tightening of disclosure on non-financial reporting and an increased focus of disclosures on non-financial concepts, objectives and measures. Hence, the risk management of a preparer gains in importance with regard to non-financial aspects of the business activity.
Climate change is the biggest social challenge facing the globalised world. The aim of this paper is to investigate the requirements for governance structures in regional sustainability programmes against climate change.
The study is an explorative case study. It is based on a literature review and expert interviews. It also involves the participatory observation of working groups meetings, and a design thinking workshop.
In spite of their enormous importance, little is known about the institutional conditions of the regional governance of climate change projects in Germany.
For this reason, the research project focuses on the important aspect of networking and governance structures. Consequently, the investigation will contribute to answering the question of which institutional framework conditions can raise the likelihood of climate change projects having a sustainable effect.
The outcomes of the application
This research has not only practical implications for the single case. The exploration of the critical factors of success also offers other regions important food for thought in shaping their governance structures. In particular, the design thinking process and the business network in the District of Steinfurt offer valuable points of reference.

Reliable information processing is an indispensable task in Smart City environments. Heterogeneous sensor infrastructures of individual information providers and data portal vendors tend to offer a hardly revisable information quality. This paper proposes a correlation model-based monitoring approach to evaluate the plausibility of smart city data sources. The model is based on spatial, temporal, and domain dependent correlations between individual data sources. A set of freely available datasets is used to evaluate the monitoring component and show the challenges of different spatial and temporal resolutions.

Mobile Eye Tracking in Landscape Architecture: Discovering a New Application for Research on Site
(2018)
This chapter presents the process of establishing a laboratory for mobile eye tracking focussing
on real-world, open-space environments within the field of landscape architecture at
the Osnabrück University of Applied Sciences (D) as well as the latest results from the feasibility
study ‘Point de Vue’, which defines the basis for qualitative interaction analyses in
landscape architecture. Eye tracking is a tool that has been used extensively in the domains
of psychology, marketing, usability and user experience in remote and mobile applications,
but has rarely been used in real-world open spaces because of technical limitations. To
check the possibilities of mobile eye tracking as a new application in open spaces, several
exploratory tests and a feasibility study with long-term experiments have been carried out
in urban settings as well as in world famous parks such as ‘Grosser Garten’ in Hannover (D)
and ‘Stourhead’ in Wiltshire (GB). These experiments have shown extraordinary results that
enable us to use mobile eye tracking as a new tool in open space research to gain knowledge
about how people act, react and interact in open-space environments. Being able to see and
understand what catches one’s eye and the response to it will be a guide to better design.
