Abstract:
This study examines how the form of management's earnings guidance (point, narrow range, wide range) affects analysts' earnings forecasts. Results from two experiments demonstrate that: (1) guidance form has no effect on analysts' forecasts made immediately after the guidance; and (2) after the actual earnings announcement, guidance form and the relationship of the earnings guidance to actual earnings (guidance error) interact in their effect on analysts' forecasts. After the actual earnings announcement, guidance error leads to higher (lower) analysts' forecasts for firms with downwardly (upwardly) biased guidance; this effect of guidance error is magnified by a narrow range and reduced by a wide range, compared to a point estimate. These results suggest that treating the mean of the range endpoints as equivalent to a point estimate and failing to consider effects after the release of actual earnings may paint an incomplete picture of how management guidance affects analysts and investors. It also offers useful information to managers who issue earnings guidance, and presents a challenge to the psychology literature regarding the effects of information precision on judgment and decision making.

Abstract:
The Australian construction industry is highly reliant on the local labour force and those employed within it undertake a wide variety of roles ranging from labouring to management. In the past 20 years construction has seen record levels of employment; however lack of skilled labour is becoming problematic. Australia, like most industrialised countries, has an ageing population due to falling birth rates, increased life expectancy and the ageing of the large post-World War II ‘baby boom’ generation. Deciding on a career is one of the most fundamental activities in a young person’s life and the role of the school career counsellor is crucial in this process. This research examined secondary school career counsellor’s knowledge of construction, their perceptions of it as a good career choice and how often they directed male and female students to investigate construction as a career. Comparisons using paired t-tests found career counsellors perceived construction to be a better career option for young men, and directed them more frequently than women, to explore construction careers. The findings also indicate that an educative model, where students and counsellors gain firsthand knowledge from people working in the industry, may counter negative gender stereotypes associated with this area of work and encourage more young people, both male and female, to consider a career in the construction industry.

Abstract:
Purpose – The purpose of this paper is to call for an integrative approach to career research aiming to avoid both fragmentation and closure of the field through the discussion of a wide range of perspectives on career or career situations. The paper discusses the specificity of this integrative approach vs others, like the traditional approach or the multi or transdisciplinary approaches. Design/methodology/approach – The work is based on a review of the career literature, and an analytic comparison of existing research approaches across this body of literature. Findings – The paper shows the tendency of career theory to stick to narrow views of a career. The paper highlights the importance of taking into account the wide variety of career situations, which results from the fact that careers are necessarily located in time and space. The paper provides examples that invite to better explore career differences and seek for alternative explanations to career experiences. Because career dynamics are marked both by individual agency and different levels of structures, a more integrative kind of career research should thus trigger richer conversations among researchers regarding the complexity of the inhabited world. Originality/value – The specific added value of the integrative approach suggested in this paper is to open new routes for a career theory that could become stronger and enhance its power to illuminate a wide range of issues.

Abstract:
This article addresses the problem of providing career guidance to professionals who are expected to be made redundant. The aim of this thesis is to develop and to do expert-evaluation of the Outplacement Model for Employees Career Promotion (hereinafter referred to as “Model”). The study was developed in the Latvia University of Agriculture, the Institute of Education and Home Economics within the Master study programme Career Counsellor. An expert evaluation of the Model was carried out with the participation of 5 experts in the field of career counselling and personnel management. In general, expert assessments of the overall Model rating (7-9 points) are close to the maximum possible rating (10 points). The provision of Outplacement services in Latvia has a wide range of benefits to the employee, employer and society as a whole. The developed Model will help employees to become more aware of their abilities and return to the labour market soon, after leaving their previous job. The Model can be used by career guidance providers for organizations and employers, career counsellors, and companies providing outplacement services.

Abstract:
To boost the existence of career-learning environments in Dutch vocational education, the innovation project ‘Career Orientation and Guidance (COG) in Secondary Vocational Education’ started in 2012. In this article, we describe the effects of this project on the level of policy formulation and implementation by means of three case studies. Data were collected at three schools through interviews, observations of meetings and teacher training, and analysis of policy documents. We conclude that a dialogue between managers and teachers, as well as among teachers is essential for changes in the learning environment of the students, since formulating a school-wide strategic policy requires communication between the different levels of the organisation, and clear tactical policy or operational plans require teacher teams and their team leaders to engage in substantive dialogues about the Career Orientation and Guidance innovation process. Instructional as well as transformational leadership stimulates a dialogical work environment for teachers and their managers, which is necessary for a dialogical career-learning environment for students.

Abstract:
Research background: The paper uses labor economics and career theory to design an integrative approach to career research focusing on new occupations and career development. Purpose of the article: The purpose of this paper is to call for an integrative approach to career research aiming to characterize labor market trends and discuss perspectives on careers using highly skilled migrants from Central and Eastern Europe as a case. The paper discusses the specificity of career development in the context of the Industry 4.0. and an integrative approach vs. other approaches. Methods: The methodology insists on several ways that enable a triangular analysis. The research combines in-depth-analysis of bibliographic data in the Web of Science database, unstructured interviews with top managers/co-owners of multinational companies in August and September 2020 as a base for writing two narrative cases. Findings & Value added: Findings show the tendency of career theory to provide a narrow view of a career. They highlight the trends in considering the wide variety of career situations, which results from the fact that careers locate in time and space. The paper provides examples to explore career differences better and seek for alternative explanations to career experiences. Because career dynamics are influenced by individual characteristics and career development practices, a more integrative approach to career research must address the complexity of labor markets. The added value is to encourage discussions about career theory focusing on a wide range of issues.

Abstract:
AbstractThe U.S. labor market continues to grapple with a “skills gap” (Marshall & Craig, 2019): a disconnect between the skills employers need and the number of job-seekers with those skills. Compounded by historically low unemployment rates, this gap is leaving employers with unfilled jobs and narrow talent pipelines. Concurrently, there are lingering concerns regarding underrepresentation of women and minorities in certain sectors of the labor market—particularly occupations in science, technology, engineering, and mathematics (STEM). This article examines how the traditional interest-only career guidance tools used in education significantly influence the gender-based skills gaps that persist in high-demand careers and introduces YouScience, a company that is helping ameliorate the skills gap by combining measures of aptitudes and interests in a new career discovery platform. We close by presenting action steps for students, parents, educators, and counselors, as well as positing possible effects of COVID-19 on career exploration and counseling.

Abstract:
We used an in vitro system that eliminates competing guidance cues found in embryos to determine whether substratum topography alone provides important neurite guidance information. Dissociated embryonic Xenopus spinal cord neurons and rat hippocampal neurons were grown on quartz etched with a series of parallel grooves. Xenopus neurites grew parallel to grooves as shallow as 14 nm and as narrow as 1 microm. Hippocampal neurites grew parallel to deep, wide grooves but perpendicular to shallow, narrow ones. Grooved substrata determined the sites at which neurites emerged from somas: Xenopus neurites sprouted from regions parallel to grooves but presumptive axons on rat hippocampal neurons emerged perpendicular to grooves and presumptive dendrites emerged parallel to them. Neurites grew faster in the favored direction of orientation and turned through large angles to align on grooves. The frequency of perpendicular alignment of hippocampal neurites depended on the age of the embryos from which neurons were isolated, suggesting that contact guidance is regulated in development. Collectively, the data indicate that substratum topography is a potent morphogenetic factor for developing CNS neurons and suggest that in addition to a role in pathfinding the geometry of the embryo assists in establishing neuronal polarity. In the companion paper (A. M. Rajnicek and C. D. McCaig (1997) J. Cell Sci. 110, 2915–2924) we explore the cellular mechanism for contact guidance of growth cones.

Abstract:
Many school employers struggle with teacher turnover challenges despite their use of wide-ranging teacher retention initiatives. Emphasizing a new Talent Centered Education Leadership approach, this article relies on a theory-building methodology that leverages the theories of career choice and Herzberg’s motivation-hygiene, empirical literature that examines the differentiated needs of teachers throughout the stages of their career, and modern strategic human resource management practices, to argue that school leaders should intentionally design a supportive employee experience for teacher support. Guidance is provided for the addressing of staffing issues in hard-to-staff secondary schools, accounting for the total employee experience journey from entry to retirement.

Abstract:
Purpose – The purpose of this paper is to empirically compare managers with employees in other occupations on Big Five and narrow personality traits to identify a distinctive personality profile for managers. Design/methodology/approach – An archival data set representing employees in a wide range of business sectors and organizations was utilized to compare trait scores of 9,138 managers with 76,577 non-managerial employees. Profile analysis (PA) with MANOVA and analysis of covariance was used to compare managers and non-managers on Big Five traits Openness, Conscientiousness, Extraversion, Agreeableness, and Emotional Stability; and narrow traits Assertiveness, Optimism, Work Drive, and Customer Service Orientation. Findings – As hypothesized, compared to non-managers, managers had significantly higher scores across nine traits, all of which correlated significantly with managerial career satisfaction. Research limitations/implications – Although job tenure and managerial level are not examined, the findings align with managerial competence models, the Attraction-Selection-Attrition model, and vocational theory and raise questions for research on the adaptive value of these traits for managers’ satisfaction and effectiveness. Practical implications – The results carry practical implications for selection, placement, training, career planning for managers, and particularly for their professional development. Social implications – A distinctive personality profile for managers clarifies the occupational identity of managers, which contributes to public and professional understanding of managers and their roles. Originality/value – This study is original in reporting an empirical, theoretically grounded personality profile of managers that includes both Big Five and narrow traits.

Abstract:
Under våren 2020 konstaterades att coronaviruset Covid-19 är en pandemi. Detta medförde restriktioner inom skolvärlden som innebar en påtvingad förändring att bland annat studie- och yrkesvägledningen nu skulle ske digitalt. Med frågeställningarna ”Hur ser utvecklingen av den snäva och vida digitala vägledningen ut för studie- och yrkesvägledare inom gymnasieskolan”, ”Vilka för- och/eller nackdelar ser studie- och yrkesvägledare inom gymnasieskolan med digital vägledning?” samt ”Vilka önskemål finns hos studie- och yrkesvägledare inom gymnasieskolan kring eventuell kompetensutveckling när det gäller digital vägledning?” är vår förhoppning att vi ska uppnå studiens syfte. Syftet är att undersöka huruvida verksamma studie- och yrkesvägledare på kommunala gymnasieskolor i sju kommuner i norra Sverige anser sig besitta de kompetenser som behövs för att anpassa sig till ett eventuellt nytt arbetssätt med digital vägledning, samt om och i så fall hur detta har utvecklats i samband med Covid-19. En kvalitativ forskningsmetod med semistrukturerade intervjuer användes för insamling av data. Vi har analyserat resultatet med hjälp av karriärteorin Social Cognitive Career Theory (SCCT), och dess begrepp upplevd självförmåga, förväntat utfall och personliga mål. Av denna studie framgår att den snäva vägledningen fungerar relativt väl digitalt, medan den vida vägledningen upplevs som en utmaning. I resultaten lyfts fördelar med digital vägledning som effektivitet och tillgänglighet samt nackdelar som brist på personlig kontakt. Det framgår även att videosamtal föredras framför telefonsamtal bland de studie- och yrkesvägledare vi intervjuat, samt att efterfrågan på kompetensutveckling uppfattas som minimal. Framledes kan informanterna se att en kombination av traditionell och digital vägledning är att föredra, även när det blir möjligt att genomföra mer vägledning på plats.
In the spring of 2020, it was declared that the coronavirus Covid-19 is a pandemic. This led to restrictions in the school generally that meant a forced change that, among other things, career guidance would now take place digitally. With the questions ”What is the development of the narrow and wide digital guidance for career counsellors in upper secondary school?”, ”What advantages and/or disadvantages do career counsellors in upper secondary school see with digital guidance?” and ”What are the wishes of career counsellors in upper secondary school regarding possible competence development in digital guidance?” our hope is that we will achieve the purpose of the study. The aim is to investigate whether active career counsellors at municipal upper secondary schools in seven municipalities in northern Sweden consider themselves to possess the skills needed to adapt to a possible new way of working with digital guidance, and if so how this has developed in connection with Covid-19. A qualitative research method with semi- structured interviews was used for data collection. We have analyzed the results using Social Cognitive Career Theory (SCCT), and its concept of self efficacy, outcome expectations and personal goals. This study shows that the narrow guidance works relatively well digitally, while the wide guidance is perceived as a challenge. Our results highlights benefits of digital guidance such as efficiency and accessibility as well as disadvantages such as lack of personal contact. Other results indicates, among other things, that video calls are preferred to telephone calls by the career counsellors when it comes to career guidance, and that the demand for competence development is perceived as minimal. In the future, the informants can see that a combination of traditional and digital guidance is preferable, even when it becomes possible to implement more face-to- face guidance.

Abstract:
Many students change their choice of secondary school programme or fail to complete their studies which results in a great cost to society or personal costs for the student. The purpose is to examine the experiences of two groups of upper secondary school students regarding their choice of upper secondary school programme. The questions we wanted answers to were: what influenced the student’s choice of study, what support did the students receive from comprehensive school and what might have caused them to choose another programme. The study was carried out in two focus groups where one of the groups was made up of students who had chosen the “right” programme and the other made up of students who had chosen the “wrong” programme. One thing that influenced the student’s choice of upper secondary school programme was whether or not the programme provided eligibility to higher studies which they had heard from primary school and parents was a choice that would give them many possibilities in the future. It appeared that there had not been much of a guidance process for developing career management skills which could have given the students support in reflecting over their transition to upper secondary school. The students’ interests and the parents and people near the students influenced the students’ choices. The study shows that students needed a longer guidance process and a clearer understanding of its purpose. Narrow and wide guidance varied depending on a student’s comprehensive school. They would have needed a better description of the consequences such as what study demands were required for the programme and what moving or commuting would mean in practice.

Abstract:
I läroplanen för grundskola, förskoleklass och fritidshem 2011 står det att skolan ansvarar för att varje elev efter genomgången grundskola kan göra väl underbyggda val av fortsatt utbildning och yrkesinriktning. Forskning inom studie- och yrkesvägledning visar på stora brister hur området integreras i skolan. Syftet med vårt examensarbete är att undersöka lärarnas perspektiv på studie- och yrkesvägledning i årskurs 1–6. För att få svar på våra frågeställningar har vi valt att använda oss av enkäter. Resultatet visar att lärarna saknar tillräckliga kunskaper för att integrera studie- och yrkesvägledning i undervisningen, men de anser att studie- och yrkesvägledning är viktigt. En lärare menar att “Det är ju det hela skolgången syftar till: att förbereda för ett kommande yrkesliv”.
The swedish curriculum for compulsory school, pre-school class and after-school center 2011 states that the school is responsible for each pupil after completing compulsory school can make well-founded choices of further education and vocational orientation. Research in study- and career guidance shows major shortcomings in how the area is integrated into the school. The purpose of our study is to investigate the teachers perspectives on study- and career guidance in grades 1–6. To get answers to our questions, we have chosen to use surveys. The results show that teachers lack sufficient knowledge to integrate study- and career guidance in teaching, but that they believe that study- and career guidance is important. One teacher says that “This is what the whole schooling is about: to prepare for a future professional life".

Abstract:
Globally, choosing the right tertiary programme for university (higher) education is quite a difficult task for students. A wide range of programmes are offered by the individual universities which differ in terms of delivery modes and entry requirements. Technology inclusion in the 21st century has paved the way for the proliferation of electronic/computing systems such as electronic counseling (e-counseling) and electronic learning (e-learning). By employing a quantitative research instrument (questionnaire) to ascertain technology acceptance of Senior High School (SHS) in Ghana, this chapter proposes a web-based (e-counseling) expert system which will match students' backgrounds with the right tertiary programme towards career development. Evaluation of our proposed approach suggests that majority of the selected students (80%) out of 100 who used the system accepted and embraced it. Such a system will therefore solve and improve career guidance, counseling, and development problems of SHS students in Ghana.

Abstract:
This article describes the development of MAHLE piston technology with the goal of meeting increasing requirements of advanced, highly efficient gasoline engines. The new EVOLITE® lightweight piston from MAHLE is a continuation of the development of its predecessor, the EVOTEC® 2, and is based on the EVOTEC® design concept. This concept differs from the design approach of previous decades in that the piston geometry has inverted asymmetry on the thrust and antithrust side. A narrow thrust side is combined with a wide, elastic antithrust side for skirt guidance. The light, robust EVOTEC® 2 piston is available with ring carrier or cooling gallery - Figure 1. The EVOLITE® concept represents further refinement of the EVOTEC® design concept by increasing asymmetry further. By geometrically optimizing the box wall connection between the skirt and crown, the lifetime has been increased by up to 8 times in comparison with the EVOTEC® 2, depending on stress location, while the weight has been reduced by up to 5%. Friction, which is critical for low CO2 emissions, is also reduced with this new piston type.

Full text
Abstract:
The concept of leak-before-break (LBB) is often used in safety cases for pressure systems, particularly in the nuclear industry. An important factor in making a LBB case is in the prediction of the leak rate of fluid through a crack. This paper presents a summary of a programme of work, which had the aim of improving guidance on leak rate evaluation for the LBB procedures in the R6 defect assessment methodology. Methods of calculating leak rates have been reviewed, and this has led to a crack morphology model being proposed, which represents single-phase isothermal compressible flow through a crack. In the crack morphology model, the flow is assumed by default to be fully rough turbulent, and the effective roughness to vary between a local roughness value for narrow cracks, to a global value (i.e. the overall crack contours) for wide cracks. The effect of pressure drops due to changes in the flow direction at crack turns has also been included. Calculations using the model show that the friction factor relation due to Spence et al. gives better agreement with measured flow rates than that due to Button et al., which tends to overestimate the flow rate for the examples studied. The inclusion of an inertial pressure term arising from changes in overall flow direction appears to be justified.

Full text
Abstract:
Image-guided, minimally-invasive cochlear implant surgery is a novel “keyhole” surgical approach for placing a cochlear implant electrode array eliminating the need for a wide-field mastoidectomy approach. Image guidance is used for path planning which is followed by the construction of a customized micro-stereotactic frame to drill a narrow channel from the skull surface to the cochlea. Herein, we present an insertion tool that uses roller wheels to advance the electrode array through the narrow tunnel and into the cochlea. Testing in a phantom revealed that when compared to insertions with surgical forceps, the new insertion tool was on average 26s faster, produced complete insertions more often (i.e. in 6/6 trials, vs. 1/6), and reduced array buckling (0/6 trials vs. 5/6). The tool provides a viable solution to complete the last step of this novel, minimally-invasive procedure. It also provides the advantage over previously developed manual insertion tools of enabling the surgeon to blindly actuate the roller wheel tool to advance the electrode into the tunnel. This allows the surgeon to visualize and guide insertion into the cochlea from a more advantageous visual perspective.
