Abstract
Purpose
This paper aims to investigate if a Cartesian robot system for kiwifruit harvesting works more effectively and efficiently than an articulated robot system. The robot is a key component in agricultural automation. For instance, multiple robot arm system has been developed for kiwifruit harvesting recently because of the significant labor shortage issue. The industrial robots for factory automation usually have articulated configuration which is suitable for the tasks in the manufacturing and production environment. However, this articulated configuration may not fit for agricultural application due to the large outdoor environment.
Design/methodology/approach
The kiwifruit harvesting tasks are completed step by step so that the robot workspace covers the canopy completely. A two-arm, Cartesian kiwifruit harvesting robot system and several field experiments are developed for the investigation. The harvest cycle time of the Cartesian robot system is compared to that of an articulated robot system. The difference is analyzed based on the workspace geometries of these two robot configurations.
Findings
It is found that the kiwifruit harvesting productivity is increased by using a multiple robot system with Cartesian configuration owing to its regular workspace geometry.
Originality/value
An articulated robot is a common configuration for manufacturing because of its simple structure and the relatively static factory environment. Most of the agricultural robotics research studies use single articulated robot for their implementation. This paper pinpoints how the workspace of a multiple robot system affects the harvest cycle time for kiwifruit harvesting in a pergola style kiwifruit orchard.

Abstract
The Department of Oriental Printed Books and Manuscripts incorporates collections which were previously included in the Departments of Printed Books and of Manuscripts. A Department of Oriental Manuscripts was formed out of the latter in 1867, the Oriental printed books being added from the former department in 1892. Prior to these dates, any catalogues which were issued were technically publications of the parent departments. All, however, are included in this list for convenience.

Abstract
Many jurisdictions fine illegal cartels using penalty guidelines that presume an arbitrary 10% overcharge. This article surveys more than 700 published economic studies and judicial decisions that contain 2,041 quantitative estimates of overcharges of hard-core cartels. The primary findings are: (1) the median average long-run overcharge for all types of cartels over all time periods is 23.0%; (2) the mean average is at least 49%; (3) overcharges reached their zenith in 1891–1945 and have trended downward ever since; (4) 6% of the cartel episodes are zero; (5) median overcharges of international-membership cartels are 38% higher than those of domestic cartels; (6) convicted cartels are on average 19% more effective at raising prices as unpunished cartels; (7) bid-rigging conduct displays 25% lower markups than price-fixing cartels; (8) contemporary cartels targeted by class actions have higher overcharges; and (9) when cartels operate at peak effectiveness, price changes are 60–80% higher than the whole episode. Historical penalty guidelines aimed at optimally deterring cartels are likely to be too low.

Abstract
This chapter engages Heidegger’s notion of caring-for-others to consider what it means to care authentically for young students who are struggling to engage in their professional education. While care is commonly understood as an emotive or cognitive state, from Heidegger’s perspective, caring for students is expressed in human action. In “Being and Time”, Heidegger examines how humans care for one another in variable ways in the course of everyday life and distinguishes between “inauthentic” and “authentic” modes of caring. The author critically builds upon Heidegger’s underdeveloped analysis, which articulates a binary between “leaping in” for others (inauthentic modes), and “leaping ahead” of others (authentic modes). From within this conceptual binary, the author argues that authentic care could be mistaken for the educator’s capacity to somehow always care for students in leaping ahead modes, and that such a view leaves little room for the possibility of pedagogic situations that sometimes call educators to leap in for students. Drawing on an Australian youth work lecturer’s story about her experience caring for a student, the author shows how any authentic caring on the educators’ part is predicated on students leaping ahead of themselves, toward their own futural selves as caring professionals in the world.

Abstract
Purpose
The purpose of this paper is to examine The Chronicle of Higher Education, a leading site for higher education news and politics, and its representation of historically black colleges and universities (HBCUs).
Design/methodology/approach
Frames are strong discursive tools that can help social actors achieve the following: define and solve problems, shape public opinion, increase the productivity of interpersonal negotiations and “serve as a foundation of public discourse, such as negotiation, on a mass-communication level”. As such, this research is guided by both higher education literature of HBCUs and media framing theories and methods in an attempt to identify potential problems and opportunities for improvement of the presentation of HBCUs nationally in the USA.
Findings
This study reveals that when the frames are viewed in concert-funding challenges at HBCUs, status differential between predominantly white institutions vs HBCUs, questionable leadership practices at HBCUs and achievement success, what one sees is an unflattering picture depicted in the Chronicle of Higher Education of HBCUs, as second-hand universities that are poorly managed, outdated and are a drain on the economy. Any one of these themes, alone, is not problematic, but when taken as a whole, their entirety represents a troubling picture – one that is inaccurate because HBCUs have and continue to serve an important role in society: educating African Americans.
Originality/value
This paper concludes with pragmatic implications of the negative findings about HBCUs as well as discusses tactics proponents HBCUs should use to combat the negative depictions.

Abstract
Findings regarding the relationship between biological sex and job stress remain inconsistent. In the present chapter, we suggest that this is due to the overly simplistic and synonymous treatment of biological sex and gender. Specifically, researchers have operationalized gender as sex, neglecting the inherent complexity of the gender construct. To address this, we take a more nuanced approach and develop a theory around the effects of biological sex and gender on job stress, considering how sex, gender, sex-based prescribed gender roles and work roles interact to create role conflict. We predict that a lack of congruence between any of the aforementioned variables results in various types of role conflict, leading to stress, and requiring coping. Drawing on the literature on role conflict, emotional labor, and facades of conformity, we introduce the concept of gender façades as a coping mechanism. Theoretical and practical implications are discussed.

Abstract
In a multicase qualitative study, inclusive school leaders attempted to move their schools from the excessive use of suspension; they employed positive behavioral intervention and support (PBIS) as an alternative they thought would be therapeutic rather than punitive. However, the PBIS system traded a disciplinary system of control for a medicalized system of restoring order. Unwanted behavior came to be defined as evidence of possible behavioral disability. Hence, the PBIS system exchanged one deficit identity of “disorderly” student for another of “disordered” student, subsuming other considerations of race, class, and gender identity. Following the study’s findings, this chapter proposes more liberatory practices for PBIS that interrupt dominant culture discourses of normal behavior and power, and hold promise for establishing justice, rather than simply reinstating order.
